Problems solved by technology

[0002] At present, large and medium-sized spraying equipment in my country can carry a large amount of spraying liquid to spray a large area of ​​farmland, but the working width of large-scale paddy field spraying machinery is generally more than 12 meters, the capacity of the medicine box is more than 1500L, and the grounding specific pressure of the unit is large. , serious damage to the mud bottom layer, easy to trap vehicles, light weight of rice field operation machinery is an urgent problem to be solved, and most of the existing online drug mixing devices use hydraulic mixing liquid, and the mixing uniformity of the chemical liquid cannot be guaranteed
[0003] Patent application number 201210585002.2 discloses a vehicle-mounted drug mixing device, which realizes separate storage of liquid medicine and water and uses high-speed water flow to realize online mixing of liquid medicine; patent application number 201020140068.7 discloses an online drug mixing device , the device realizes the independent storage of pesticide stock solution and water, and uses the principle of negative pressure and turbulent flow to achieve automatic, rapid and uniform mixing of pesticide and water. None of the above inventions can effectively reduce the volume of the medicine box and reduce the ground pressure of the pesticide application machine
The patent with application number 201310194432.6 discloses a variable spray device for automatic drug mixing. This device realizes separate storage of liquid medicine and water, and is suitable for vehicle-mounted and large and medium-sized sprayers. The uniformity is poor, and the mixing precision of the liquid medicine is low
The patent with the application number 201310607287.x discloses a pesticide mixing device, including a sprayer, a medicine storage pool, and a medicine dispensing pool. This invention solves the problems of separation of the sprayer from the spraying system, uneven mixing of pesticides, and low mixing efficiency. , but it is not suitable for vehicle use, and cannot meet the requirements of real-time online dispensing of paddy field sprayers
[0004] To sum up, in the existing technology, the weight reduction of paddy field pesticide application machinery has not been effectively solved, and the liquid medicine is mixed by relying on hydraulic force, the mixing uniformity is poor, and the mixing precision of the medicine liquid cannot be guaranteed.

Embodiment Construction

[0028] The scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 Shown is a schematic diagram of the structure of the water suction and filtration device of the drug mixing device of the paddy field pesticide applicator. The device includes a water pump 4, a secondary filter 6 and a plurality of parallel water intake branches. The water pump 4 is connected to the secondary filter 6. The first-stage filter 6 is connected to a plurality of parallel water intake branches in sequence, and the water intake branches are sequentially connected by a switch valve 7, a primary filter 8, a water inlet pipe 9, and a water collection tank 10 through pipelines. The sump 10 is used to collect the water in the shallow water layer of the paddy field and perform coarse filtration to facilitate the water intake of the water inlet pipe 9. The primary filter 8 further filters the water collected by the wat...

Abstract

The invention discloses a pesticide mixing device and a pesticide mixing method for a paddy field pesticide applying machine. The device comprises a forced water-absorbing and filter device and a pesticide mixing device, wherein the forced water-absorbing and filter device consists of a water suction pump, a secondary filter and a plurality of parallel water getting branches which are connected in sequence; the pesticide mixing device comprises a small water tank, a pesticide mixing tank, a liquor tank and a pesticide stock solution tank. Liquid level sensors are arranged on the pesticide mixing tank, the small water tank and the liquor tank; a rotary propeller type stirrer is further arranged on the pesticide mixing tank. The pesticide mixing device adopts a mode of getting water on line in real time and mechanically stirring and mixing to prepare liquor and sufficiently mix the liquor, so that the liquor mixing uniformity is improved, the volume of the liquor tank is greatly reduced, the weight of the pesticide applying machine is reduced and the grounding specific pressure is reduced. The pesticide mixing device is mainly used for realizing the light weight of the pesticide applying machine and improving the online pesticide mixing uniformity. The pesticide mixing device can be applied to a large-medium-sized boom spraying mechanical device of paddy field operation.
