Description

Technical Field

[0001] This utility model relates to the field of fertilizer application technology, and in particular to a lightweight fertilizer application device. Background Technology

[0002] Chemical fertilizers are fertilizers manufactured through chemical methods or processed from ore. They contain one or more nutrients required for crop growth, provide nutrients for plant growth, promote their development, and improve yield and quality. They are widely used in agricultural production scenarios such as farmland and orchards. There are many types, including single-element fertilizers, compound fertilizers, and slow-release fertilizers. They are characterized by high nutrient content and rapid fertilizer effect, but they must be applied in a reasonable manner to avoid problems such as soil compaction.

[0003] In existing technologies, when spreading fertilizer, there are various types of agricultural implements. Among them, backpack implements integrate fertilizer box and drive device into backpack structure. Operators can carry the equipment on their shoulders and move flexibly in the field. The opening and speed of the spreading nozzle can be adjusted by manual or automatic control mechanism to make the fertilizer evenly spread near the crop roots, thus meeting the needs of spreading fertilizer in complex terrain.

[0004] However, when spreading fertilizer using backpack agricultural implements, a handheld spreader is usually used. During the spreading process, the spreader may become tilted because the hand is in one position for a long time, which will cause the spreading direction to deviate, resulting in uneven distribution of fertilizer, over-fertilization in some areas or missed areas, and affecting the uniformity of crop growth. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a lightweight fertilizer spreading device.

[0026] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a lightweight fertilizer spreading device, including an anti-tilting mechanism 1, a positioning mechanism 2 provided on the inner wall of the anti-tilting mechanism 1, a fertilizer inlet chamber 11, an empty tube 13 provided on the top side of the fertilizer inlet chamber 11, the top side of the fertilizer inlet chamber 11 being fixedly connected to the bottom side of the empty tube 13, a sphere 14 provided on the inner surface of the empty tube 13, the inner surface of the empty tube 13 being slidably connected to the outer side of the sphere 14, a rope 16 provided on one side of the sphere 14, and the rope 16 being connected to the outer side of the sphere 14. One end is fixedly connected, and an inner rod 15 is provided on the outer side of the rope 16. The outer side of the rope 16 and the inner wall of the inner rod 15 are slidably connected through it. One end of the inner rod 15 contacts one side of the sphere 14. A counterweight 110 is provided at one end of the rope 16. The top of the counterweight 110 is fixedly connected to one end of the rope 16. A guide rod 111 is provided on the inner wall of the counterweight 110. The inner wall of the counterweight 110 and the outer side of the guide rod 111 are slidably contacted. One end of the guide rod 111 is fixedly connected to one side of the inlet cavity 11. The bottom end of the inlet cavity 11 is connected to... The top end of the second inlet cavity 12 is correspondingly fitted. A drive roller 112 is provided on the top side of the first inlet cavity. The top side of the first inlet cavity 11 is rotatably connected to the bottom end of the drive roller 112. A feedback cavity 113 is provided on the top end of the drive roller 112. The top end of the drive roller 112 is fixedly connected to the bottom end of the feedback cavity 113. A fixing block 19 is provided on one side of the empty tube 13. One side of the empty tube 13 is fixedly connected to one end of the fixing block 19. An L-plate 17 is provided on the outer side of one end of the fixing block 19. The outer side of one end of the fixing block 19 is slidably connected to the inner wall of the L-plate 17. Next, a spring 18 is provided on the inner wall of L plate 17. The inner wall of L plate 17 is fixedly connected to one end of spring 18, and the other end of spring 18 is fixedly connected to one side of fixed block 19. A fertilizer spreading disc 115 is provided on the inner side of fertilizer inlet cavity 2 12. The inner side of fertilizer inlet cavity 2 12 is rotatably connected to the bottom side of fertilizer spreading disc 115. A motor 114 is provided at the center of the bottom side of fertilizer spreading disc 115. The center of the bottom side of fertilizer spreading disc 115 is fixedly connected to the output end of motor 114. The top end of motor 114 is fixedly connected to the bottom side of fertilizer inlet cavity 2 12.

[0027] In this embodiment, when the lightweight fertilizer spreading device is in use, the two fertilizer inlet chambers 12 and 11 are connected in the above corresponding manner. A fertilizer spreading disc 115 is installed inside the fertilizer inlet chamber 12, and a fertilizer inlet is installed on the fertilizer inlet chamber 11. Then, by connecting the fertilizer inlet to the backpack fertilizer pipeline, the fertilizer inside enters the fertilizer inlet chamber 12. At this time, by starting the motor 114, the fertilizer spreading disc 115 is rotated. During the rotation, the fertilizer is thrown out by centrifugal force, thereby completing the spreading work.

[0028] An empty tube 13 is installed on the top side of the first fertilizer inlet 11. The empty tube 13 is made of transparent material and has a sphere 14 inside. The sphere 14 can slide inside the empty tube 13. Ropes 16 are installed on both sides of the sphere 14, and a counterweight 110 is fixed to the bottom end of the rope 16. The counterweight 110 is located on one side of the first fertilizer inlet 11, and an inner rod 15 is designed on the inner side of one end of the empty tube 13. The inner rod 15 can also slide a short distance in the empty tube 13. Therefore, when the seeding operation is carried out, if the first fertilizer inlet 11 and the second fertilizer inlet 12 tilt simultaneously, the counterweight... Block 110 will cause the ball 14 to move in an inclined direction, while simultaneously applying external force to the inner rod 15, causing the inner rod 15 to slide out of the empty tube 13 a short distance. During the movement of the rope 16, a drive roller 112 is designed on one side of the rope 16. The rope 16 rotates the drive roller 112, and a feedback chamber 113 is installed at the top of the drive roller 112. The feedback chamber 113 has fan blades inside, and the rotation of the fan blades alerts the sowing personnel that the sowing is currently tilted, allowing them to quickly correct the tilt and ensure even sowing.

[0029] An L-plate 17 is installed at one end of the inner rod 15. A spring 18 is designed on the inner wall of the L-plate 17. The other end of the spring 18 is fixedly connected to the fixing block 19. At the same time, one end of the fixing block 19 is fixed to the empty tube 13. When the whole is balanced, the spring 18 uses its own retraction property to synchronously reset the inner rod 15 and the ball 14, thus visually ensuring that the sowing state is in the correct manner. Example

[0030] like Figure 1 - Figure 2 As shown, the positioning mechanism 2 includes a positioning plate 21. A fixing member 22 is provided on the inner wall of the top end of the positioning plate 21. The inner wall of the top end of the positioning plate 21 is threadedly connected to the outer side of the fixing member 22. The outer side of the fixing member 22 is threadedly connected to the inner wall of the first fertilizer inlet 11. A second fertilizer inlet 12 is provided on the outer side of the bottom end of the positioning plate 21. The outer side of the bottom end of the positioning plate 21 is fixedly connected to one side of the inner wall of the second fertilizer inlet 12.

[0031] In this embodiment, a positioning plate 21 is installed on one inner wall of the fertilizer inlet cavity 2 12. When the fertilizer inlet cavity 2 12 is combined with the fertilizer inlet cavity 1 11, the positioning plate 21 is engaged with the groove on the fertilizer inlet cavity 1 11 to achieve initial positioning of the fertilizer inlet cavity 1 11 and the fertilizer inlet cavity 2 12. Subsequently, a fixing member 22 is threaded through the positioning plate 21 and connected to the fertilizer inlet cavity 1 11 by using a tool. In this way, the positioning plate 21 and the groove can be engaged to ensure the accuracy of the installation position of the two, and the threaded connection of the fixing member 22 can enhance the stability of the joint. Furthermore, when the fertilizer inlet cavity 1 11 and the fertilizer inlet cavity 2 12 are separated, they can be quickly disassembled to process the residual fertilizer inside.

[0032] Working principle:

[0033] like Figure 1 - Figure 5 As shown, the sphere 14 slides within the empty tube 13. Ropes 16 are installed on both sides of the sphere 14, and a counterweight 110 is fixed to the bottom end of each rope 16. The counterweight 110 is located on one side of the fertilizer inlet chamber 11, and an inner rod 15 is designed inside one end of the empty tube 13. The inner rod 15 can also slide short distances within the empty tube 13. Therefore, during the seeding operation, if the fertilizer inlet chamber 11 and fertilizer inlet chamber 2 tilt simultaneously, the counterweight 110 will cause the sphere 14 to move in the tilting direction, simultaneously exerting an external force on the inner rod 15, thus... The inner rod 15 slides out of the empty tube 13 with a short distance. During the movement of the rope 16, a drive roller 112 is designed on one side of the rope 16. The rope 16 rotates the drive roller 112. A feedback chamber 113 is installed at the top of the drive roller 112. The feedback chamber 113 is designed with fan blades inside. The rotation of the fan blades reminds the spreading personnel. When the whole is balanced, the spring 18 uses its own retraction property to synchronously reset the inner rod 15 and the ball 14, ensuring that the spreading state is correct in a visual way.

[0034] By engaging the slot on the first fertilizer inlet 11 with the positioning plate 21, the first fertilizer inlet 11 and the second fertilizer inlet 12 are initially positioned. Then, by using a tool, the fixing piece 22 is threaded through the positioning plate 21 and connected to the first fertilizer inlet 11. In this way, the engagement structure between the positioning plate 21 and the slot can be used to ensure the accuracy of the installation position of both.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
