Definitions

  • This model is part of the agricultural technique sector and presents a solution for weed control in pastures.
  • spray peaks are used, which drop water droplets with pressurized herbicide that reach the entire surface on which they are applied, as if all the plants present were weeds.
  • the selectivity is given by the herbicide used, which determines if all plants die or not.
  • Common sprayers have restrictions on use when wind speed is greater than 15 kilometers per hour, to avoid problems of drift of the herbicide, which can damage other sensitive crops and achieve a good application.
  • the sprayers apply medium to high volumes, greater than 65 liters per hectare.
  • UBV equipment that can apply less than 15 liters of broth per hectare, known as ultra low volume (UBV) equipment.
  • UBV ultra low volume
  • These teams produce and release very small drops, which when dragged by the wind can go great distances, even with little wind, or even evaporate the drops on a hot day. This has the problem that the application can be disastrous, because the herbicide will stop somewhere unwanted, for example to another crop, causing damage and loss of profits. In the case and the drops evaporate, the treatment effect is null and the desired objective is not achieved. It is for this reason that UBV equipment is not recommended for herbicide applications.
  • the machine is formed by the following components: - a tool holder chassis (A - figure 1) that carries a 200 liter tank (B - figures 1 and 2) for water and herbicide (broth), which gives it great autonomy working without having to recharge water;
  • a parallel bobbin regulator system (C - figure 2), which allows to safely and reliably regulate the flow of liquid that it reaches the droppers;
  • a dropper dosing system (D - figure 2) which, according to the calibration of each dropper, allows to regulate the amount of water and herbicide that reaches the carpet and how they are distributed on it.
  • the dispenser is formed by a series of parallel bobbins and set of calibrated drippers that allow an accurate and lasting calibration.
  • the machine can be calibrated to spend between four and ten liters per hectare
  • an applicator system (E - figure 3) that we call carpet, that rubs weeds, scraping the surface of the leaves, turning them in many cases and applying the water with the herbicide. It has two jacks or legs on each side (F - figure 1), in order to prevent the carpet from touching the ground when the machine is detached from the tractor.
  • the measurements of the carpet are such that the width of the carpet is one and a half times the width of the machine chassis (1.5 ratio). This ratio of 1, 5 does that the carpet does not drip and in many weeds, turn the leaves back to apply the herbicide on the face under the leaves where there is less wax, greatly improving the penetration of the herbicide.
  • the dosing system is attached to the chassis by bolt clips.
  • a bobbin H - figure 2
  • the equipment works without pressure, only with the force of gravity.
  • the herbicide used with this machine is glyphosate at a concentration of 10% (nine parts of water and one of glyphosate). As a lot of foam is produced in the tank, with the movement of the machine during work, an antifoam should be added to the broth.
  • ADVANTAGES Unlike the rope machine, in the carpet machine the dispenser and the applicator are separated, so there is no variation in the cost of broth while the equipment is working. Once calibrated, the equipment always spends the same amount of broth.
  • the applicator system which is the carpet, gently rubs the weeds and scrapes, to apply a broth film on them.
  • the machine is calibrated so as not to drip the herbicide and the continuous contact with the weeds does not affect it, so the operator only takes care of operating the tractor after having regulated it. This makes the machine have a good performance, without wasting time, since there are no breaks or damage during operation.
  • the machine also has a herbicide tank high enough for the operator to easily see the amount of remaining stock.
  • the carpet applicator does not have the drawback of wind drift in conventional sprayers and wind or non-wind operation can be operated without any problem. This allows control of weeds when desired and not only when it is possible because of the wind, which gives it an important advantage to be able to choose the best moment of control.
  • the carpet machine allows a lower cost in weed control.
  • the carpet weed killer machine solves the problem of weed control in cultivated grasslands, improvements in cover, seedlings of forage plants and natural fields.
  • selective herbicides that are expensive and now you can use glyphosate which is a total herbicide, but much cheaper. It allows to control the weeding, without affecting the pastures that you want to clean, killing only the weeds and leaving intact the productive forage plants.
  • this machine By being mounted on the three-point hitch of an agricultural tractor, this machine can perform herbicide applications on large areas and have commercial use in fields and pastures.
  • the dosing system and the applicator do not carry pressure and operate by gravity. To this is added that the machine applies herbicide selectively on weeds and it does not touch the productive plants. - The selectivity instead of being given by the herbicide, is given due to the difference in height between the weeds and the pasture that you want to protect. The regulation of the application height is obtained by varying the height of the three-point hitch of the tractor.
  • the rope machine has the disadvantage when working with weeds such as Sida rombifolia (Sida) and similar ones that have hard twigs; the twigs hook the ropes, detaching them from the pipes, which produces a blasting of herbicide on the pasture, causing the death of a significant amount of pasture plants. Besides the cost that this represents and the damage to the pasture, a lot of operative time is lost, trying to solve this damage.
  • the action of the herbicide is reinforced because scrape turns the leaves, applying the herbicide also below the leaves.
  • the carpet machine touching the weeds, as it has a ratio of 1.5 between the width of the carpet and the width of the chassis, has a curvature in the carpet that causes it to caress the weeds, turning the leaves in many cases and also applies the herbicide to the abaxial face (below) of the leaf.
  • This in some weeds like Cynara cardunculus (Thistle of Castile) is excellent since the adaxial face (above) has an important waxy cover that hinders the penetration of the herbicide.
  • the carpet is also a rough and slightly abrasive element that, unlike the ropes, scrapes The surface of the weed leaf, helping the action of the herbicide.
  • the carpet machine is an ultra low volume (UBV) machine especially suitable for applying total herbicides, without causing damage to other sensitive crops. If we compare the carpet applicator, with ultra low volume (UBV) machines, common UBV machines apply less than 15 liters per hectare and the carpet machine applies stock volumes of 4 to 10 liters per hectare. For this reason it can be considered as an ultra low volume (UBV) machine.
  • UBV ultra low volume
  • the advantage of the carpet over that of conventional UBV is that the carpet is not affected by the wind and does not suffer any type of drift the application of the herbicide. There is also no risk of the herbicide evaporating, because the drops produced by the drippers are large and do not evaporate like those of UBV equipment that are very small.
  • the carpet machine represents an advantage from the economic point of view, since a very low cost herbicide can be used, at very low doses to control weeds in grasslands. If selective herbicides were used in these pastures, the cost would be very high or technically very difficult due to the botanical composition of the grasslands. In a meadow of grasses (type Festuca) and legumes (type white clover and lotus), to control thistles or senecio in the second year of the pasture, control is expensive for the cost of herbicides to be used and good control is hardly achieved, without affecting any of the botanical components of the pasture. With the use of the carpet machine weed control is simple, cheap and with very good results.
  • a - Water and herbicide (broth) can be regulated per hectare to apply volumes of 4 to 10 liters per hectare, which ensures that we wet weeds but do not drip on the pasture. This is achieved with the faucets in parallel and with the use of calibrated drippers.
  • b - Being able to know the herbicide expenditure per hectare, the working width of the machine and the working speed of the tractor, a cost calculation can be made, to know how much it costs to use this machine per hectare, in a given property.
  • c The shape of the fall of the carpet that hangs from the chassis, determines a relationship between the width of the carpet and the width of the chassis, whose default value is 1.5. This causes the broth that comes out of the drippers to spread perfectly through the carpet and wet it completely and evenly, avoiding blasting.
  • d Selectively control large weeds, something that selective herbicides cannot do because they need the weed to be too small or a seedling to kill it.
  • e - It is not affected by the wind during application.
  • f It can be used in pastures and improvements in coverage of already established forage legumes, without affecting them.
  • g It allows to lower the treatments because it uses low amounts of herbicide per hectare and the herbicides it uses are cheap.
  • this machine is a tool that helps the care of the environment, which represents an ecological advantage.
  • the carpet weed killer machine can be used in natural fields to clean weeds and enhance the most productive species.
  • the low maintenance cost of this machine is another of the qualities that should be highlighted.
  • the carpet machine also does not require agricultural tractors with great engine power to be used, so it represents an economy in tractor fuel consumption and can be used with any small agricultural tractor.
