[0001] The utility model relates to the technical field of fertilization, in particular to a device for adjusting the fertilizer output of a solid fertilizer applicator. Background Art

[0002] During the fertilization process of a solid fertilizer applicator, a storage barrel inside the fertilizer applicator is used to store fertilizers. Generally, a flap valve is arranged at the bottom of the storage barrel to control the fertilizer output. However, when the flap valve is in use, fertilizer residues are likely to stay inside the valve and cause scaling, resulting in an uneven surface of the flap, inconsistent frictional resistance between the flap and the tank body, and jitter and jamming during the movement of the flap, which affects the smooth operation of the flap valve. Content of the Utility Model

[0003] The purpose of the utility model is to solve the defect that scaling on the surface of the flap in the prior art causes jamming and affects the smooth operation of the flap valve, and to provide a device for adjusting the fertilizer output of a solid fertilizer applicator.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] Design a device for adjusting the fertilizer output of a solid fertilizer applicator, including a valve seat. One end of the valve seat is fixedly installed with a feeding pipe. A chute is opened in the middle of the side wall of the feeding pipe, and the chute extends through to the inside of the valve seat. An insertion plate is slidably arranged inside the chute. The end of the insertion plate away from the feeding pipe is fixedly installed with a connecting seat. A lead screw is rotatably arranged at the other end of the valve seat, and the end of the lead screw is threadedly connected to the inside of the connecting seat. A cleaning mechanism is fixedly installed on the upper side of the valve seat.

[0006] Preferably, the cleaning mechanism includes a mounting plate. A plurality of connecting shafts are rotatably arranged inside the mounting plate. The lower ends of the connecting shafts extending below the mounting plate are fixedly installed with cleaning brushes, and the upper ends extending above the mounting plate are fixedly installed with gears. Adjacent gears are meshed with each other, and one side gear is connected to an external motor.

[0007] Preferably, the bottom bristles of the cleaning brush are in contact with the upper surface of the insertion plate.

[0008] Preferably, a fixing frame is fixedly installed on the lower surface of the valve seat, and a containing box is placed inside the fixing frame. The containing box is located below the cleaning brush.

[0009] Preferably, a flexible pad is fixedly installed on the inner wall of the feeding pipe close to the connecting seat, and the lower end of the flexible pad is in contact with the upper surface of the insertion plate.

[0010] An adjusting device for the fertilizer output of a solid fertilizer applicator proposed by the present utility model has the beneficial effects that: during the working process of the adjusting device for the fertilizer output of the solid fertilizer applicator, the fertilizer inside the storage barrel will fall into the feeding pipe through the discharge port. The lead screw can drive the connecting seat to move, and the movement of the connecting seat can drive the insertion plate to move. Adjusting the specific position of the insertion plate can adjust the size of the flow hole inside the feeding pipe, thereby controlling the fertilizer output inside the feeding pipe.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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 of the embodiments.

[0016] Example 1: Refer to Figures 1-3, A device for adjusting the fertilizer output of a solid fertilizer applicator, comprising a valve seat 1. One end of the valve seat 1 is fixedly installed with a feeding pipe 2. The upper end of the feeding pipe 2 corresponds to the fertilizer outlet of the storage barrel inside the fertilizer applicator. Fertilizer is stored in the storage barrel, and the fertilizer can enter the feeding pipe 2 through the fertilizer outlet. A chute 3 is provided in the middle of the side wall of the feeding pipe 2, and the chute 3 extends through to the inside of the valve seat 1. A plug board 4 is slidably arranged inside the chute 3. The plug board 4 is located inside the feeding pipe 2. The inside of the feeding pipe 2 can be blocked by the plug board 4. At this time, the fertilizer can be prevented from passing through the feeding pipe 2. A connecting seat 5 is fixedly installed at the end of the plug board 4 away from the feeding pipe 2. A lead screw 6 is rotatably arranged at the other end of the valve seat 1. The lead screw 6 is connected to an external motor. The external motor can drive the lead screw 6 to rotate. The end of the lead screw 6 is threadedly connected to the inner side of the connecting seat 5. The rotation of the lead screw 6 can drive the connecting seat 5 to move, and the movement of the connecting seat 5 can drive the plug board 4 to move.

[0017] The plug board 4 has two extreme position states. One is that the end of the plug board 4 is fully fitted with the inside of the feeding pipe 2. At this time, the plug board 4 is far from the lead screw 6, and the inside of the feeding pipe 2 is in a completely closed state, and the fertilizer cannot pass through the feeding pipe 2. The other is that the end of the plug board 4 is not fitted with the inside of the feeding pipe 2 at all. At this time, the plug board 4 is close to the lead screw 6, and the inside of the feeding pipe 2 is not blocked at all, and the fertilizer can pass through the feeding pipe 2.

[0018] One end of the plug board 4 close to the feeding pipe 2 is semi-circular. The movement of the plug board 4 driven by the lead screw can control the degree of fit between the plug board 4 and the inside of the feeding pipe 2. The deeper the plug board 4 penetrates into the feeding pipe 2, the smaller the opening inside the feeding pipe 2, and the less the fertilizer output per unit time. The fertilizer output inside the feeding pipe 2 can be controlled by driving the lead screw 6 to rotate.

[0019] A flexible pad 13 is fixedly installed on the inner wall of the feeding pipe 2 on the side close to the connecting seat 5. The lower end of the flexible pad 13 contacts the upper surface of the plug board 4. The inside of the flexible pad 13 is made of a rubber structure. The fertilizer and debris on the surface of the plug board 4 can be scraped off through the flexible pad 13, and it can prevent the fertilizer debris from being carried out together when the plug board 4 is moved out of the feeding pipe 2.

[0020] A cleaning mechanism is fixedly installed on the upper side of the valve seat 1. Through the cleaning mechanism, the surface of the plug plate 4 can be cleaned. Although the flexible gasket 13 can play a role in blocking fertilizer debris, there may still be finer fertilizer powder residues on the surface of the plug plate 4. The cleaning structure can further clean the surface of the plug plate 4. The cleaning mechanism includes a mounting plate 7. A plurality of connecting shafts 8 are rotatably arranged inside the mounting plate 7. The lower end of the connecting shaft 8 extending below the mounting plate 7 is fixedly installed with a cleaning brush 9, and the upper end of the connecting shaft 8 extending above the mounting plate 7 is fixedly installed with a gear 10. The bottom bristles of the cleaning brush 9 are in contact with the upper surface of the plug plate 4. Adjacent gears 10 are meshed with each other. One side gear 10 is connected to an external motor. Through the external motor, one side gear 10 can be driven to rotate. The rotation of one side gear 10 will drive all gears 10 to rotate. The rotation of the gears 10 will drive the cleaning brush 9 to rotate through the connecting shaft 8. The rotation of the cleaning brush 9 can clean the powder residues remaining on the upper surface of the plug plate 4.

[0021] A fixing frame 11 is fixedly installed on the lower surface of the valve seat 1. A containing box 12 is placed inside the fixing frame 11. The containing box 12 is located below the cleaning brush 9. The powder residues falling when the cleaning brush 9 cleans the plug plate 4 will enter the containing box 12 and be collected. The containing box 12 is convenient to take and can clean the powder residues collected inside the containing box 12.

[0022] The valve seat of this device has no outer shell covering, which is convenient for repairing and cleaning the inside of the device. If the plug plate 4 is not thoroughly cleaned by the cleaning brush 9, the staff can also clean the unclean positions of the plug plate 4 specifically, or clean the inside of the chute 3 regularly, which can prevent the inside of the chute 3 from being blocked and affecting the normal sliding of the plug plate 4.

[0023] Working principle: During the operation of the fertilizer output regulating device of this solid fertilizer applicator, the fertilizer inside the storage hopper will fall into the feeding pipe 2 through the discharge port. By starting the external motor to drive the rotation of the lead screw 6, the rotation of the lead screw 6 will drive the movement of the connecting seat 5. The movement of the connecting seat 5 can drive the movement of the plug board 4, adjust the specific position of the plug board 4, so as to adjust the size of the flow hole inside the feeding pipe 2, and thus control the fertilizer output inside the feeding pipe 2. During or after fertilization, when starting the motor to drive the rotation of the lead screw 6 and the lead screw 6 rotates to drive the plug board 4 away from the feeding pipe 2, the fertilizer and debris on the surface of the plug board 4 can be scraped off through the flexible pad 13. At the same time, start the external motor to drive the rotation of the gear 10, and the rotation of the gear 10 will drive the cleaning brush 9 to rotate through the connecting shaft 8. When the cleaning brush 9 rotates, it can clean the upper surface of the moving plug board 4, and effectively clean the powder residue on the surface of the plug board 4, avoiding the long-term accumulation of powder impurities on the surface of the plug board 4 to form scale. The surface of the scale-formed plug board 4 is uneven, which will cause jamming during movement and affect the smoothness of the operation of this regulating device. The powder debris during the cleaning of the cleaning brush 9 will fall into the storage box 12 and be collected, which is convenient for cleaning the inside of the storage box 12.

[0024] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
