Abstract
Description
Technical Field
[0001] This invention relates to the field of pesticide spraying equipment technology, and in particular to a self-propelled pesticide spraying device. Background Technology
[0002] Currently, in the process of planting seedlings in forestry, in order to prevent seedlings from being attacked by pests and diseases, it is necessary to spray pesticides on the seedlings regularly. When spraying pesticides onto seedlings or leaves, pesticide spraying devices are generally used. Pesticide spraying devices include shoulder strap type, hand push type, and self-propelled type. When dealing with a large number of seedlings or trees, self-propelled pesticide spraying devices are often required.
[0003] Traditional self-propelled pesticide spraying devices are inefficient because the spray nozzles remain stationary throughout the spraying process. Even if some nozzles are adjustable, they can only spray at a specific angle, resulting in poor spraying effectiveness. Furthermore, when the pesticide level in the storage tank is low, it's difficult to provide an effective warning to operators. Although traditional self-propelled pesticide spraying devices have filters at the water pump inlet, these filters easily become clogged with debris after a period of use, hindering pesticide passage. Cleaning the filters requires stopping the machine, further reducing spraying efficiency. Summary of the Invention
[0004] In view of this, the present invention provides a self-propelled pesticide spraying device to solve the problem that the pesticide spraying pipe of the traditional self-propelled pesticide spraying device is ineffective in spraying pesticides because it remains stationary during the spraying process.

[0011] Furthermore, the linkage assembly includes a fixed plate, a U-shaped sliding rod, a sliding sleeve, a linkage rack, a linkage gear, a reciprocating screw, a second pulley, and a screw nut.

[0015] This invention, through the cooperation of the linkage component and the pesticide spraying mechanism, enables the first pulley to rotate while the shaft of the stirring motor rotates. The first pulley then drives the second pulley to rotate via a belt, which in turn drives the reciprocating screw to rotate. The screw nut, under the action of the two helical grooves at the upper end of the reciprocating screw, moves the U-shaped sliding rod and the two linkage racks up and down, thereby driving the two linkage gears to rotate clockwise and counterclockwise. This causes the two pesticide spraying pipes to swing up and down, thus improving the spraying effect of this self-propelled pesticide spraying device.
[0016] This invention, through the setting of a liquid level monitoring component, enables the annular floating block, along with the vertical sliding rod, lifting ring, L-shaped lifting rod, and low liquid level warning sign, to move downwards when the distance between the bottom surface of the annular floating block and the bottom surface inside the pesticide storage tank reaches one-tenth of the total depth of the pesticide storage tank. At this time, the low liquid level warning sign is located behind the controller, thus providing an effective warning to the staff. Furthermore, the liquid level monitoring component can provide an effective warning without the need for a sensor, which not only reduces costs and energy consumption but also makes it more reliable and avoids liquid level sensor failures.
[0017] This invention, through the cooperation of a stirring shaft and an automatic unclogging mechanism, enables the driving disc to rotate during the rotation of the stirring shaft. The driving disc then drives the actuating column to rotate, and the actuating column moves the unclogging brush back and forth, thereby sweeping away the debris covering the upper surface of the filter box, preventing it from affecting the normal passage of pesticides. Moreover, cleaning the debris on the surface of the filter box does not require stopping the machine, thus improving the spraying efficiency of this self-propelled pesticide spraying device.
[0018] This invention, through the setting of the linkage component, can drive two pesticide spraying pipes to swing up and down without the need for a separate motor drive, thereby reducing costs, saving energy consumption, and having a simple structure and convenient maintenance.

With the cooperation of the stirring shaft 401 and the automatic unclogging mechanism 8, the unclogging brush 801 can move back and forth left and right during the rotation of the stirring shaft 401, thereby sweeping away the debris covering the upper surface of the filter box 303 and avoiding affecting the normal passage of pesticides.
[0037] The specific usage and function of this embodiment: In this invention, when it is necessary to spray pesticides on seedlings or trees, the pesticides are first added into the pesticide storage tank 3. Then, the staff sits on the seat 105 and starts the drive motor 109 through the controller 107, and controls the shaft of the drive motor 109 to rotate clockwise, so that the active pulley drives the driven pulley to rotate through the belt, and then drives the drive shaft 101 to rotate clockwise through the driven pulley, so that the two wheels roll clockwise, thereby driving the self-propelled pesticide spraying device to move forward. During the forward movement, the controller 107 controls the telescopic rod of the electric push rod 1010 to move back and forth, thereby driving the drive rack 1011 to move back and forth. Then, the drive rack 1011, which moves back and forth, drives the steering gear 1012 to rotate clockwise or counterclockwise, so that the steering shaft 102 drives the steering wheel 103 to turn left and right. When the self-propelled pesticide spraying device is moved to the seedling site, the water pump 505 is started by the controller 107, so that the pesticide in the pesticide storage tank 3 enters the two pesticide spraying pipes 501 through the delivery pipe 504, the three-way fitting 503, and the two delivery hoses 502. Then, the pesticide is sprayed on the seedlings on the left and right sides through the spray heads on the outside of the two pesticide spraying pipes 501. During the pesticide spraying process, the stirring motor 4 is started by the controller 107, so that the rotating shaft of the stirring motor 4 drives the stirring shaft 401 to rotate, thereby stirring the stirring paddle to avoid the precipitation of the pesticide inside the pesticide storage tank 3. As the shaft of the stirring motor 4 rotates, it drives the first pulley 402 to rotate. The first pulley 402 then drives the second pulley 607 to rotate via a belt, which in turn drives the reciprocating screw 606 to rotate. The screw nut 608, under the action of the two helical grooves at the upper end of the reciprocating screw 606, drives the U-shaped sliding rod 602 and the two linkage racks 604 to move up and down reciprocally, thereby driving the two linkage gears 605 to rotate clockwise and counterclockwise, thus causing the two pesticide spraying pipes 501 to swing up and down reciprocally. As the pesticide inside the pesticide storage tank 3 is slowly pumped out by the water pump 505, the pesticide liquid level inside the pesticide storage tank 3 will slowly drop. Then, the annular float block 705 will float on the pesticide liquid surface under the action of buoyancy. When the distance between the bottom surface of the annular float block 705 and the bottom surface inside the pesticide storage tank 3 is one-tenth of the total depth inside the pesticide storage tank 3, the annular float block 705, along with the vertical sliding rod 704, the lifting ring 701, the L-shaped lifting rod 702, and the low liquid level warning sign 703, moves downward. At this time, the low liquid level warning sign 703 is located behind the controller 107, which can provide an effective warning to the staff. Moreover, the liquid level monitoring component 7 can provide an effective warning without the need for a sensor, which not only reduces the cost and power consumption, but is also more reliable and avoids the phenomenon of liquid level sensor failure. During the rotation of the stirring shaft 401, the drive disc 803 will rotate, and then the drive disc 803 will drive the actuating column 804 to rotate. The actuating column 804 will then move the cleaning brush 801 back and forth, thereby sweeping away the debris covering the upper surface of the filter box 303, avoiding affecting the normal passage of pesticides. Moreover, when cleaning the debris on the surface of the filter box 303, there is no need to stop the machine for cleaning, thereby improving the spraying efficiency of this self-propelled pesticide spraying device.
