Abstract
Description
Technical Field
[0001] This invention relates to the field of crop seedling fertilization equipment, and more particularly to a fertilizer applicator. Background Technology
[0002] In crop cultivation, fertilization involves applying fertilizer to the soil or spraying it onto the crops to provide them with the necessary nutrients. See application number CN201720593641.1, which discloses a "disc-type rubber trenching fertilizer applicator." This technical solution uses a turntable inside the fertilizer tank. The rotation of the turntable causes the fertilizer to rotate, allowing the fertilizer moving along the edge of the turntable to contact a discharge baffle, thus scraping the fertilizer into the discharge hopper. However, fertilizers are categorized into chemical fertilizers, organic fertilizers, farmyard manure, granular fertilizers, and powdered fertilizers, each with different moisture content, viscosity, and particle size. Especially with higher viscosity fertilizers, relative sliding between the fertilizer and the turntable is likely to occur after contact with the inner wall of the fertilizer tank, leading to unstable fertilizer application and affecting crop growth. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a fertilizer applicator that can prevent relative sliding between the fertilizer and the turntable.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a fertilizer applicator, including a fertilizer storage tank and a fertilizer cutting knife; the fertilizer storage tank includes a tank body, a turntable and a dividing ring; a discharge port is provided at the bottom of the side end of the tank body, the turntable is rotatably disposed at the bottom of the inner cavity of the tank body, the dividing ring is disposed in the inner cavity of the tank body, and the outer ring of the dividing ring is connected to the inner wall of the tank body.
[0005] The fertilizer cutter is located at the discharge port and is used to guide the fertilizer on the turntable to the discharge port for discharge.
[0006] The beneficial effects of this invention are as follows: By adding a dividing ring to the inner cavity of the fertilizer storage tank, the fertilizer can only pass through the inner ring of the dividing ring and fall onto the turntable. Due to surface tension, the fertilizer will move a certain distance along the dividing ring towards one end of the turntable before falling onto the edge of the turntable and accumulating. Thus, the fertilizer inside the tank is divided into two layers by the dividing ring, while the fertilizer on the turntable will not come into contact with the inner wall of the tank. This reduces the resistance to rotating the fertilizer on the turntable, allowing the fertilizer to move to the discharge port of the tank under the drive of the turntable. Then, the fertilizer on the edge of the turntable is discharged from the discharge port under the guidance of the fertilizer cutter, achieving the purpose of stabilizing the amount of fertilizer applied.

[0014] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0015] Please refer to Figure 1 As shown, the present invention provides a fertilizer applicator, including a fertilizer storage tank 1 and a fertilizer cutting blade 2; the fertilizer storage tank 1 includes a tank body 11, a turntable 12 and a dividing ring 13; a discharge port 111 is provided at the bottom of the side end of the tank body 11, the turntable 12 is rotatably disposed at the bottom of the inner cavity of the tank body 11, and the dividing ring 13 is disposed in the inner cavity of the tank body 11, with the outer ring of the dividing ring 13 connected to the inner wall of the tank body 11;
[0016] The fertilizer cutter 2 is located at the discharge port 111, and the fertilizer cutter 2 is used to guide the fertilizer on the turntable 12 to the discharge port 111 for discharge.
[0017] As can be seen from the above description, the beneficial effects of the present invention are as follows: A partition ring 13 is added to the inner cavity of the barrel 11 of the fertilizer storage tank 1, so that the fertilizer can only pass through the inner ring of the partition ring 13 and fall onto the turntable 12. Due to the surface tension, the fertilizer will move a certain distance along the partition ring 13 toward one end face of the turntable and then fall onto the turntable 12 and accumulate. Thus, the fertilizer in the barrel 11 is divided into two layers by the partition ring 13, and the fertilizer on the turntable 12 will not contact the inner wall of the barrel 11, thereby reducing the resistance to rotating the fertilizer located on the edge of the turntable 12. This allows the fertilizer to move to the discharge port 111 of the barrel 11 under the drive of the turntable 12. Then, the fertilizer located on the edge of the turntable 12 is discharged from the discharge port 111 under the guidance of the fertilizer cutter 2, thus achieving the purpose of stabilizing the amount of fertilizer applied.
[0018] Please refer to Figure 1As shown, the separating ring 13 is further inclined toward the turntable 12.
[0019] As described above, the fertilizer falls onto the turntable 12 along the separating ring 13.
[0020] Please refer to Figure 1 As shown, the turntable 12 is further provided with a fertilizer guide platform 121, and the diameter of the fertilizer guide platform 121 gradually decreases away from the turntable 12.
[0021] As can be seen from the above description, the fertilizer guide platform 121 can be used to easily guide the fertilizer located in the middle of the barrel 11 to the edge of the turntable 12.
[0022] Please refer to Figure 1 As shown, a sealing ring 14 is further provided in the inner cavity of the fertilizer storage tank 1, and the sealing ring 14 is located between the turntable 12 and the partition ring 13.
[0023] As can be seen from the above description, the fertilizer sealing ring 14 can intercept fertilizer from flowing from the edge of the turntable 12 into the space between the turntable 12 and the bottom plate of the barrel 11, thus avoiding affecting the normal rotation of the turntable 12.
[0024] Please refer to Figures 1 to 3 As shown, the above-mentioned fertilizer applicator further includes an adjustment component 3 disposed at the discharge port 111. The adjustment component 3 includes a reciprocating device 31 and a fixing member 32. The fertilizer cutter 2 includes a cutter 21 and a connecting plate 22. The cutter 21 is located in the inner cavity of the barrel 11. The connecting plate 22 is connected to one end of the cutter 21. One end of the connecting plate 22 is hinged to the fixing member 32. The end of the connecting plate 22 away from the fixing member 32 is hinged to the movable end of the reciprocating device 31.
[0025] As can be seen from the above description, by using the reciprocating device 31 to drive the movable end to move, the cutter 21 can rotate around the fixed part 32 as the rotation center, thereby adjusting the amount of fertilizer discharged from the discharge port 111.
[0026] Please refer to Figure 2 and Figure 3 As shown, the reciprocating device 31 further includes an adjusting bolt 311, a first nut 312, a second nut 313, and a threaded rod 314; the first nut 312 is threadedly connected to the adjusting bolt 311 and is connected to the barrel 11; the second nut 313 is threadedly connected to the adjusting bolt 311; the threaded rod 314 is disposed on the second nut 313 and is threadedly connected to the connecting plate 22.
[0027] As described above, by rotating the adjusting bolt 311, the second nut 313 moves on the adjusting bolt 311, thereby adjusting the angle of the cutter 21. Furthermore, the connecting plate 22 is threadedly connected to the threaded rod 314, which can constrain the movement of the connecting plate 22 in the vertical direction, thereby preventing friction between the cutter 21 and the turntable 12 and thus avoiding abnormal noise.
[0028] Please refer to Figure 2 and Figure 3 As shown, the reciprocating device 31 further includes a spring 315, which is sleeved on the threaded end of the adjusting bolt 311 and is located between the first nut 312 and the second nut 313.
[0029] As can be seen from the above description, the elastic force of spring 315 can prevent the adjusting bolt 311 from shifting when it is rotated.
[0030] Furthermore, the fastener 32 is a bolt, which is threadedly connected to the connecting plate 22.
[0031] As can be seen from the above description, the movement of the connecting plate 22 in the vertical direction is further constrained.
[0032] An application scenario of the fertilizer applicator of the present invention: During the fertilization process, a dividing ring 13 is added to the inner cavity of the fertilizer storage tank 11, so that the fertilizer can only pass through the inner ring of the dividing ring 13 and fall onto the turntable 12. Due to the surface tension, the fertilizer will move a distance along the dividing ring 13 toward one end of the turntable and then fall onto the turntable 12 and accumulate. Thus, the fertilizer in the tank 11 is divided into two layers by the dividing ring 13, while the fertilizer on the turntable 12 will not contact the inner wall of the tank 11, thereby reducing the resistance to rotating the fertilizer on the turntable 12. This allows the fertilizer to move to the discharge port 111 of the tank 11 under the drive of the turntable 12. Then, the fertilizer on the edge of the turntable 12 is discharged from the discharge port 111 under the guidance of the fertilizer cutter 2, thus achieving the purpose of stabilizing the amount of fertilizer applied.
[0033] Example 1
[0034] A fertilizer applicator, please refer to Figure 1As shown, the system includes a fertilizer storage tank 1 and a fertilizer cutting knife 2. The fertilizer storage tank 1 includes a tank body 11, a turntable 12, and a separating ring 13. A discharge port 111 is provided at the bottom of the side end of the tank body 11. The turntable 12 is rotatably mounted at the bottom of the inner cavity of the tank body 11. The separating ring 13 is located within the inner cavity of the tank body 11, and its outer ring is connected to the inner wall of the tank body 11. The fertilizer cutting knife 2 is located at the discharge port 111 and is used to guide the fertilizer on the turntable 12 to the discharge port 111 for discharge. The separating ring 13 is inclined towards the turntable 12. A fertilizer guiding platform 121 is provided on the turntable 12, and the diameter of the fertilizer guiding platform 121 gradually decreases away from the turntable 12. A fertilizer sealing ring 14 is provided in the inner cavity of the fertilizer storage tank 1, located between the turntable 12 and the separating ring 13.
[0035] The top of the fertilizer guide platform 121 passes through the inner ring of the partition ring 13.
[0036] Working principle: During fertilization, the addition of a partition ring 13 inside the barrel 11 ensures that the fertilizer can only pass through the inner ring of the partition ring 13 and fall onto the turntable 12. Due to surface tension, the fertilizer moves a certain distance along the partition ring 13 towards one end of the turntable before accumulating on the edge of the turntable 12. The fertilizer in the middle of the barrel 11 is guided by the fertilizer guide platform 121 and accumulates towards the edge of the turntable 12. Because the partition ring 13 divides the fertilizer inside the barrel 11 into two layers, the fertilizer on the turntable 12 does not contact the inner wall of the barrel 11, thus reducing the resistance to rotating the fertilizer on the edge of the turntable 12. This allows the fertilizer to move to the discharge port 111 of the barrel 11 under the drive of the turntable 12.
[0037] Example 2
[0038] This embodiment further defines the fertilizer applicator as including an adjustment component located at the discharge port, based on embodiment one.
[0039] Please refer to Figures 1 to 3 As shown, the adjustment assembly 3 includes a reciprocating device 31 and a fixing member 32; the fertilizer cutter 2 includes a cutter 21 and a connecting plate 22. The cutter 21 is located in the inner cavity of the barrel 11. The connecting plate 22 is connected to one end of the cutter 21. One end of the connecting plate 22 is hinged to the fixing member 32. The end of the connecting plate 22 away from the fixing member 32 is hinged to the movable end of the reciprocating device 31.
[0040] Please refer to Figure 2 and Figure 3As shown, the reciprocating device 31 includes an adjusting bolt 311, a first nut 312, a second nut 313, and a threaded rod 314. The first nut 312 is threadedly connected to the adjusting bolt 311 and is connected to the barrel 11. The second nut 313 is threadedly connected to the adjusting bolt 311. The threaded rod 314 is disposed on the second nut 313 and is threadedly connected to the connecting plate 22. The reciprocating device 31 also includes a spring 315, which is sleeved on the threaded end of the adjusting bolt 311 and is located between the first nut 312 and the second nut 313. The fixing member 32 is a bolt, which is threadedly connected to the connecting plate 22.
[0041] Working principle: When it is necessary to adjust the fertilizer output, rotate the adjusting bolt 311 to move the second nut 313 on the adjusting bolt 311, thereby driving the connecting plate 22 to rotate around the fixed part 32 as the rotation center. Consequently, the corresponding cutter 21 will show a corresponding angle change at the discharge port 111, thereby adjusting the amount of fertilizer discharged from the discharge port 111.
[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
