The invention relates to agriculture, in particular for spraying agricultural crops.
Known technical solution, in which when the setting of the sprayer consider second flow of working fluid, its concentration and the speed of the unit (patent RF №2152717, CL AM 7/00, 2000).
The closest technical solution is the way to configure spraying, including the measurement of minute fluid flow in one spray, normalized hectare of fluid flow and the speed of the unit (Spray Nozzles and Accessories, Product Catalogue 105E agrotop, page 42).
However, the known technical solution does not take into account the distance between adjacent nozzles, which does not ensure the accuracy of the adjustment of the sprayer.
Technical solution to the problem is to improve the accuracy configuration of the sprayer, the expansion of technological capabilities and reduced labor costs.
This object is achieved in that in the method of calibration of the measuring vessel to adjust the sprayer, including the measurement of minute fluid flow in one spray, normalized hectare of fluid flow and speed of movement of the unit according to the invention take into account the distance between adjacent nozzles on the boom field sprayer minute and the flow rate of liquids and one spray is determined by the formula: q=QVa/600, where q - minute flow rate of working fluid from one nozzle (l/min); Q - normalized hectare fluid flow (l/ha); V - working speed unit (km/h); and - the distance between adjacent nozzles (m), then in accordance with the normalized hectare consumption, minute flow one spray fluid, the speed of movement of the unit to determine the brand of the unit and its operating gear, and the color, the type of sprayer and pressure according to the international standard - in accordance with the normalized hectare consumption, minute flow one spray fluid, and tazrout dimensional container in the form of separate sectors, each of which corresponds to a specific normalized hectare flow of the working fluid color and type sprayer with a corresponding pressure and has horizontal lines at different levels indicating the types of units with their working gear.
The novelty of the claimed proposal due to the fact that by defining minute of fluid flow through one nozzle, according to the distance between adjacent nozzles increases the accuracy of calibration of the measuring capacitance, results in reduced labor costs and improving the setting accuracy of the sprayer.
According to the patent and technical literature is not obnarujennogo technical solution allowing to solve the problem, which allows to judge about the level of invention proposals.
The proposed solution is workable and as a result of experimental studies have provided data to support the efficacy of industrial application proposals.
The invention is illustrated in the drawing, which presents a General view of the measuring vessel to adjust the sprayer.
The method of calibration of the measuring vessel to adjust the sprayer is as follows.
Pre-measuring minute of fluid flow through one nozzle carried out according to the formula: q=QVa/600, where q - minute consumption by one spray (l/min); Q - normalized hectare flow rate (l/ha); V - working speed unit (km/h); and - the distance between adjacent nozzles on the boom field sprayer (m). Normalized hectare consumption of the liquid and the speed of movement of the unit picked on the basis of generally accepted hectare norms and velocities are used in the processing of field crops with pesticides. The distance between adjacent nozzles on the boom field sprayer, as a rule, is 0.5 m, Then in accordance with the normalized hectare and minute expenses of the working fluid, the speed of movement of the unit definition is Aut brand unit and its operating gear color, type of sprayer and pressure according to the international standard (Spray Nozzles and Accessories, Product Catalogue 105E agrotop, page 31,32) and tazrout measuring container 1 (see drawing) as separate sectors 2, each of which specify a particular normalized hectare consumption of the working fluid, the type of dispenser with corresponding pressure and has horizontal lines 3 different levels indicating the types of units with their work gear, such as a tractor MTZ (V) or tractor T-70 C (VI) in parentheses are working transmission of the tractor.
For example, one of the sectors is intended for a hectare of fluid flow 100 l/ha, the other at 200 l/ha and so on for a given hectare flow of the working fluid and the calculated momentary flow rate of the working fluid is specified types of sprayers 110-04 and 80-04 (TyrboDrop TDXL) pressure of 2-5 bar (bar). On the horizontal lines of this sector specified brand units with their work programs, for example for liquid accumulated for 30 s corresponds to the third horizontal line, it is necessary to use a tractor MTZ-82 (V) or tractor T-70 C (VI), in parentheses indicate the working transmission of the tractor. Tractors must move to the fifth and sixth gear at rated engine speed.
A specific example of the use of dimensional capacity to adjust sprayer
You must first determine what number is the number of normalized hectare of fluid flow will be handled by this field. Usually normalized hectare consumption of the working fluid is determined according to the recommendations of scientists or prospectuses for the drug.
At a certain flow rate is determined by the desired sector on the measured capacitance, for example, to 100 l/ha On this sector specialist reads, which sprays it is advisable to install. Sets them on the sprayer boom. Then proceed to the setting of the sprayer. Before leaving for the field on a stationary platform deploy boom sprayer, include tractor PTO, clean water to achieve the same spray fluid all nozzles. After that, proceed to the main point - the definition of the speed of the unit and the fluid pressure. In stationary conditions at the same venue at the rated speed of the engine is created in the discharge line of the sprayer fluid pressure at which it is assumed the work of the unit in the field. After a steady spray, a specialist with the recording time of substitutes dimensional capacity under any spray on the bar and collects the dripping water from the dispenser for the time specified on the sector dimensional capacity (60 sec). After this time removes a measuring Cup from under the spray. Next, looking at what horizontal line has been filling the volumetric capacity of the water. If the filling, coincided with what is on the mark, specialist immediately reads on this line mark and the transmission of the tractor on which the unit must operate in the field, while the fluid pressure should be the same as it was during the filling of the container.
For example, at rated engine speed filling of the measuring vessel was performed at 2, 3 ATM, and coincided with the fourth horizontal mark sector.
After these measurements the specialist clearly sets the task to the machine operator. The unit should work in field VI, the transmission of the tractor MTZ-82 at rated engine speed and the pressure of the liquid 2, 3 ATM (0.23 MPa, 33 psi, 2, 3 bar).
Unacceptable during the entire processing period of the field even a slight change these modes. If on the first passages of the unit on the field it was found that due to nevybavenost field it is impossible to work on VI transmission of the tractor at the rated engine speed, it is necessary again to make the setting of the sprayer. To create such a fluid pressure at which the filling of the measuring vessel will happen until the third or even the second horizontal line on the measuring container.
For example, at rated engine speed and the fluid pressure of 1.7 ATM. Filling mugs occurred for 60 seconds to the third horizontal line. On this line specialist reads - the unit must work in the field on V transmission tractor MTZ-82. Fluid pressure should be and the military to 1.7 ATM. On the first passages of the unit on the field agronomist and entomologist controls the flow rate of the working fluid and, if necessary, adjusts it.
Thus, for 3 to 5 minutes, using a special measuring Cup, agronomist and entomologist correctly set up the sprayer. Using the same capacity he defined the brand of tractor and working transmission, color and marking sprays. When the accepted rate of the working solution these nozzles will produce the desired droplet size that will provide the greatest efficiency of the drug.
The method of setting sprayer, including the measurement of minute fluid flow in one spray, normalized hectare of fluid flow and the speed of the unit, characterized in that take into account the distance between adjacent nozzles on the boom field sprayer minute and the flow rate of the working fluid in one sprayer;
determined by the formula
where q - minute flow rate of the working fluid in one spray, l/min;
Q - normalized hectare consumption of the working fluid l/ha;
V - working speed unit km/h;
a - the distance between adjacent nozzles, m,
then, in accordance with the normalized hectare consumption, minute flow one spray of the working fluid from near the capacity of movement of the unit to determine the brand of the unit and its operating gear and the color, the type of sprayer and pressure according to the international standard in accordance with the normalized hectare consumption, minute flow one spray fluid and tazrout dimensional container in the form of separate sectors, each of which corresponds to a specific normalized hectare flow of the working fluid color and type sprayer with a corresponding pressure and has horizontal lines at different levels indicating the types of units with their working gear.
