Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery, and mainly relates to a liquid pesticide application assembly for plant protection machinery with precise quantitative adjustment. Background Technology

[0002] Liquid pesticides are increasingly used in agricultural plant protection operations due to their easy dilution and ability to effectively cover and absorb plant surfaces during spraying. Currently used liquid pesticide spraying equipment often employs a liquid pump to pressurize the liquid pesticide and deliver it directly to the nozzle through a delivery pipe. This type of equipment lacks the function of precisely adjusting the sprayed liquid volume. This can lead to problems such as waste due to excessive application, increased application costs, and environmental pollution, or insufficient application affecting efficacy and reducing crop yield and quality. Therefore, achieving precise adjustment and control of liquid pesticide application is a crucial technical problem that must be solved. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art and, in light of the actual needs of precise liquid pesticide application, to research and design a liquid pesticide precise quantitative adjustable application monomer, so as to achieve precise liquid pesticide dosage application, scientific and rational pesticide use, and simple and convenient adjustment operation.

[0004] The objective of this invention is achieved as follows: A piston rod is axially reciprocatingly inserted into the cavity of a fixedly configured liquid storage cylinder; a one-way inlet valve is installed above the liquid storage cavity of the cylinder, communicating with the piston rod; a drive plate is axially reciprocatingly inserted into a strip-shaped through hole on the lower wall of the liquid storage cylinder, with its upper end fixed to the piston rod; a hanging active rod is axially reciprocatingly inserted into the outer bottom side of the liquid storage cylinder, with one end of the active rod connected to the drive plate; grooved connecting rods A, B, and C are respectively hinged to the outer bottom side of the liquid storage cylinder via pins A, E, and D; pin B hinges connecting grooved connecting rods A and B; pin C hinges connecting the active rod to grooved connecting rod A; pin E hinges connecting grooved connecting rods B and C; and pin F hinges connecting grooved connecting rod C to a push-pull rod; a drain cylinder is coaxially fixed at the drain end of the liquid storage cylinder. A hanging base is fixedly mounted on the lower side of the drainage cylinder. A cross groove plate is movably installed on the lower end of the hanging base. A rotating shaft is rotatably inserted into the shaft holes of the drainage cylinder, the hanging base, and the cross groove plate from top to bottom. A sleeve is rotatably fitted on the outside of the rotating shaft. A semi-circular right-side opening and closing leaf plate and a semi-circular left-side opening and closing leaf plate are symmetrically fixed on the sleeve and the rotating shaft, located inside the cavity of the drainage cylinder. The semi-circular right-side opening and closing leaf plate cooperates with the semi-circular left-side opening and closing leaf plate to close or open the drainage cylinder. The bottom ends of the rotating shaft and the sleeve are respectively inserted into the left and right groove holes of the cross groove plate. The cross groove plate is connected to a push-pull rod. A motor is fixedly mounted on the outer side of the piston rod. A crank is fixedly mounted on the motor shaft. An adjusting block is fixedly mounted on the crank and can be adjusted radially. The two ends of the drive connecting rod are respectively hinged to the adjusting block and the piston rod. This constitutes a liquid agent precise quantitative adjustable dispensing unit.

[0005] This invention utilizes the reciprocating motion of a piston rod within a storage cylinder to achieve quantitative intake and discharge of liquid pesticides. By adjusting the length of the piston rod's reciprocating stroke within the cylinder, the amount of pesticide supplied is precisely controlled. This achieves the goals of improving the utilization efficiency of liquid pesticides, maximizing their effectiveness, ensuring rational pesticide use, guaranteeing control results, reducing application costs, minimizing pesticide pollution to soil, air, groundwater, and the environment, and avoiding harm to human health. It features a novel, unique, rational, and compact structure; simple and convenient control; high precision; wide applicability; and strong adaptability. Attached Figure Description

Detailed Implementation

[0016] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A liquid agent with precise quantitative adjustable dispensing monomer comprises a piston rod 13 axially reciprocatingly inserted into the cavity of a fixedly configured storage cylinder 2; an inlet check valve 1 interconnected with the upper part of the storage cavity of the storage cylinder 2; a drive plate 14 axially reciprocatingly inserted into a strip-shaped through hole on the lower wall of the storage cylinder 2, the upper end of the drive plate 14 being fixedly attached to the piston rod 13; and an active rod 12 axially reciprocatingly inserted and suspended on the outer bottom side of the storage cylinder 2, one end of the active rod 12 being connected to the drive plate 14. Connecting the grooved connecting rods A10, B7, and C21, respectively, are hinged to the outer bottom side of the liquid storage cylinder 2 via pins A9, E20, and D6. Pin B8 hinges the grooved connecting rods A10 and B7, pin C11 hinges the drive rod 12 to the grooved connecting rod A10, and pin E20 hinges the grooved connecting rods B7 and C21. The grooved connecting rod C21 is hinged to the push-pull rod 5 via pin F22. A coaxial fixed... A drainage cylinder 3 is installed, and a hanging seat 4 is fixedly mounted on the lower side of the drainage cylinder 3. A cross groove plate 18 is movably installed on the lower end of the hanging seat 4. A rotating shaft 19 is rotatably inserted into the shaft holes of the drainage cylinder 3, the hanging seat 4, and the cross groove plate 18 from top to bottom. A sleeve 17 is rotatably fitted on the outside of the rotating shaft 19. A semi-circular opening and closing right leaf plate 16 and a semi-circular opening and closing left leaf plate 15 are respectively fixedly and symmetrically on the sleeve 17 and the rotating shaft 19, located inside the cavity of the drainage cylinder 3. The semi-circular opening and closing right leaf plate... Plate 16 cooperates with semi-circular opening and closing left leaf plate 15 to close or open the drainage cylinder 3. The bottom ends of the rotating shaft 19 and sleeve 17 are respectively inserted into the left and right slots of the cross groove plate 18. The cross groove plate 18 is connected to the push-pull rod 5. A motor 23 is fixedly arranged on the outer side of the piston rod 13. A crank 25 is fixedly mounted on the motor shaft 24 of the motor 23. An adjusting block 26 is fixedly mounted on the crank 25 and can be adjusted radially. The two ends of the drive connecting rod 27 are respectively hinged to the adjusting block 26 and the piston rod 13.

[0017] During operation, the motor 23 is started. The rotational power of the motor 23 is transmitted sequentially through the motor shaft 24, crank 25, adjusting block 26, and drive connecting rod 27 to drive the piston rod 13 to move axially and reciprocally within the liquid storage cylinder 2. When the piston rod 13 is pulled outward, the negative pressure suction within the liquid storage cylinder 2 opens the inlet check valve 1, allowing the liquid agent to fill the cylinder cavity of the liquid storage cylinder 2. When the piston rod 13 moves inward and squeezes the liquid agent, the inlet check valve 1 closes, stopping the filling. Simultaneously, as the piston rod 13 moves inward, the power is transmitted sequentially through the drive plate 14, the drive rod 12, the grooved connecting rod A10, and the grooved connecting rod A17. Connecting rod B7, grooved connecting rod C21, and push-pull rod 5 push the cross-grooved plate 18 to move on the hanging seat 4. The cross-grooved plate 18 simultaneously drives the semi-circular opening and closing left leaf plate 15 and the semi-circular opening and closing right leaf plate 16 to rotate in opposite directions inside the drainage cylinder 3, opening the drainage cylinder 3. The liquid medicine in the storage cylinder 3 is quantitatively discharged through the squeezing motion of the piston rod 13. When the motor 23 drives the piston rod 13 to move in the opposite direction, the semi-circular opening and closing left and right leaf plates 15 and 16 close the drainage cylinder 3, and at the same time, the liquid inlet check valve 1 opens, completing the operation of refilling the liquid medicine. This cycle is repeated. Adjusting the position of the adjusting block 26 on the crank 25, that is, changing the eccentric distance between the adjusting block 26 and the axis of the motor shaft 24, completes the adjustment of the reciprocating stroke distance of the piston rod 13 in the storage cylinder 2, realizing the precise quantitative discharge of the liquid medicine.
