DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Refer to Figures 1-3, a vegetable planting soil improvement device, including a support frame 1, on which a movable frame 2 is movably installed, and a screen 3 is arranged on the movable frame 2. The movable frame 2 can move back and forth on the support frame 1 to cooperate with the screen 3 to complete the soil screening operation.

[0022] A driving motor 4 is provided on the support frame 1. The driving motor 4 is connected to the movable frame 2 through a connecting mechanism. A liquid pump tank 12 is provided on the support frame 1 through a hoisting frame 10. Inside the liquid pump tank 12, there are a liquid pump chamber 13 and a rotating chamber 14. A reciprocating lead screw 15 extending outside the liquid pump tank 12 is rotatably provided in the rotating chamber 14. The reciprocating lead screw 15 is connected to the movable frame 2 through a rotating mechanism. A piston plate 16 is arranged in the liquid pump chamber 13. The piston plate 16 is hermetically and slidably installed in the liquid pump chamber 13. The piston plate 16 is connected to the reciprocating lead screw 15 through a connecting mechanism. An inlet pipe 18 and an outlet pipe 19 are installed on the liquid pump tank 12, and a spray plate 11 is installed on the outlet pipe 19.

[0023] The connecting mechanism includes a fixed frame 7 fixedly installed on the movable frame 2. A rotating frame 6 is rotatably installed on the fixed frame 7. A turntable 5 is installed on the output shaft of the driving motor 4. The rotating frame 6 is eccentrically installed on the turntable 5. Because it is eccentrically installed, once the driving motor 4 rotates, in cooperation with the rotating frame 6 and the fixed frame 7, the movable frame 2 can be driven to move back and forth on the support frame 1.

[0024] The rotating mechanism includes a rack 8 installed on the movable frame 2. A gear 9 is installed on the reciprocating lead screw 15. The rack 8 meshes with the gear 9. Because the rack 8 meshes with the gear 9, when the movable frame 2 moves back and forth on the support frame 1, the rack 8 will drive the gear 9 to rotate.

[0025] The connecting mechanism includes a connecting frame 17 threadedly sleeved on the reciprocating lead screw 15. The connecting frame 17 extends into the liquid pump chamber 13 and is fixedly connected to the piston plate 16. The connecting frame 17 is designed in a U shape, and its two branches both slidably penetrate the inner wall of the rotating chamber 14 and extend into the liquid pump chamber 13, so it has its own limit and will not rotate together with the reciprocating lead screw 15.

[0026] A first valve is provided in the inlet pipe 18, and a second valve is provided in the outlet pipe 19. Both the first valve and the second valve are one-way valves. The above two one-way valves control the one-way flow of liquid. In this solution, the inlet pipe 18 can be connected to a medicine storage tank to realize the inhalation operation of the medicine.

[0027] When the present utility model is in use, when the driving motor 4 is started, its output shaft drives the turntable 5 to rotate. Since the rotating frame 6 is eccentrically installed on the turntable 5 and the rotating frame 6 is connected to the movable frame 2 through the fixed frame 7, the rotation of the turntable 5 will drive the movable frame 2 to move back and forth on the support frame 1. The screening operation of the filled soil is realized, and large particle stones are screened out.

[0028] The back-and-forth movement of the movable frame 2 drives the movement of the rack 8. Since the rack 8 meshes with the gear 9 on the reciprocating lead screw 15, the gear 9 is rotated, and then the reciprocating lead screw 15 is rotated within the rotating cavity 14. The rotation of the reciprocating lead screw 15 causes the connecting frame 17 sleeved with a thread to perform a reciprocating motion. Since the connecting frame 17 is fixedly connected to the piston plate 16 and the special design of the connecting frame 17 prevents it from rotating with the reciprocating lead screw 15, the connecting frame 17 drives the piston plate 16 to perform a reciprocating motion within the liquid pumping cavity 13. When the piston plate 16 moves away from the liquid outlet pipe 19, a negative pressure is generated within the liquid pumping cavity 13, the first valve within the liquid inlet pipe 18 opens, and the second valve within the liquid outlet pipe 19 closes. The liquid medicine is sucked from the external storage tank into the liquid pumping cavity 13. When the piston plate 16 moves towards the liquid outlet pipe 19, the pressure within the liquid pumping cavity 13 increases, the first valve within the liquid inlet pipe 18 closes, and the second valve within the liquid outlet pipe 19 opens. The liquid medicine is squeezed out from the liquid pumping cavity 13 and sprayed out from the spraying plate 11 through the liquid outlet pipe 19, realizing the spraying and improvement of the soil. In practical applications, if it is necessary to improve the soil of a large vegetable planting area, the device can operate continuously and continuously perform the operations of screening the soil and spraying the liquid medicine. Different liquid medicines can be replaced according to different soil improvement requirements.

[0029] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
