Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to an automatic hole fertilization combination tool. Background Technology

[0002] For large-scale planting areas, manual hole application is costly and requires a large amount of manpower. To save time, strip application or broadcast application is usually carried out, but this not only wastes fertilizer but also causes environmental pollution and the plants do not absorb it well. Therefore, a hole application fertilizer applicator is proposed to improve the above situation.

[0003] For example, Chinese utility model patent (CN207427792U) discloses a fertilizer applicator, which describes: "The fertilizer applicator uses a pedal to apply force to the push rod. Under the action of the force, the push rod pushes open the automatic reset switch. As the automatic reset switch is opened, the fertilizer in the second sleeve is applied to the soil by the push rod. When the push rod resets, the fertilizer falls into the soil. The fertilizer applicator is equipped with a balancing device, which can effectively control the balance on uneven land and achieve the stability of the entire fertilizer applicator. Using foot force can more effectively improve the working efficiency of the fertilizer applicator."

[0004] The aforementioned fertilizer applicator uses foot pedal force, which is more labor-saving than pressing with both hands, but it still relies on human force for fertilization, thus requiring a large investment of labor costs and affecting fertilization efficiency. Therefore, this application proposes an automatic hole fertilization combination tool. Utility Model Content

There is no need to rely on pressing with your hands or stepping on the pedal to fertilize, which effectively improves the fertilization efficiency.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1:

[0030] Please refer to Figure 1-4 An automatic hole fertilization combination tool includes a base plate 1. A storage bin 2 is fixed at the upper end of the base plate 1. The storage bin 2 facilitates the storage of fertilizer required for multiple hole applications. In order to facilitate the stable support of the base plate 1 on the soil surface, a balancing mechanism 3 is installed on the outer side of the base plate 1. In order to automatically put fertilizer into each hole during hole application, a bottom cylinder 8 is fixed at the bottom end of one end of the base plate 1. A hollow screw cylinder 10 is rotatably connected inside the base plate 1 and located inside the bottom cylinder 8. A guide frame 11 is fixed at the bottom end of the base plate 1 and located outside the hollow screw cylinder 10. The guide frame 11 is located inside the bottom cylinder 8.

[0031] Specifically, a screw 12 is threadedly connected to the inner side of the hollow screw cylinder 10. A T-shaped lifting seat 13 is fixed to the lower end of the screw 12. The T-shaped lifting seat 13 is located at the lower end of the hollow screw cylinder 10 and is slidably connected to the guide frame 11. In order to guide the lifting and lowering movement of the T-shaped lifting seat 13, limit guide rods 14 are fixed at both ends of the T-shaped lifting seat 13. The lower end of the limit guide rod 14 passes through the guide frame 11 and is slidably connected to the guide frame 11.

[0032] A top plate 16 is fixed inside the bottom cylinder 8 and at the lower end of the T-shaped lifting seat 13. A switch assembly is provided inside the bottom cylinder 8 and at the lower end of the top plate 16. Pressure rods 15 are symmetrically fixed at the lower end of the T-shaped lifting seat 13. The lower ends of the two pressure rods 15 pass through the top plate 16 and are slidably connected to the top plate 16. When the T-shaped lifting seat 13 moves down, it is convenient to drive the pressure rods 15 down, and then use the pressure rods 15 to push open the switch assembly.

[0033] An automatic feeder 6 is fixed inside the other end of the substrate 1. The discharge port of the automatic feeder 6 is fixedly connected to a conveying pipe 7. The extraction port of the automatic feeder 6 extends to the inside of the storage bin 2. The end of the conveying pipe 7 away from the automatic feeder 6 passes through the bottom cylinder 8 and extends to the lower end of the top plate 16, so that the required fertilizer can be quantitatively conveyed between the switch assembly and the top plate 16 each time the hole is applied.

[0034] Specifically, the switch assembly includes a support shaft 17. The support shaft 17 is symmetrically rotatably connected to the lower end of the bottom cylinder 8. A switch plate 18 is fixed on the outer side of each support shaft 17 and located on the inner side of the bottom cylinder 8. The outer side of the switch plate 18 is in contact with the inner side of the bottom cylinder 8. A torsion spring 22 is provided between the outer side of each support shaft 17 and the bottom cylinder 8.

[0035] To facilitate the automatic downward movement of the T-shaped lifting seat 13, a first flat gear 19 is fixed to the outer side of the upper end of the hollow screw cylinder 10, and a reduction motor 20 is fixed inside the base plate 1 and outside the first flat gear 19. A second flat gear 21 is fixed to the output end of the reduction motor 20, and the second flat gear 21 meshes with the first flat gear 19.

[0036] Example 2:

[0037] The automatic hole fertilization tool provided in Example 1 has been further optimized, specifically, as follows: Figure 2-4 As shown, in order to protect the two support shafts 17 and avoid affecting the normal rotation and reset of the support shafts 17, a protective sleeve 23 is fixed on the outside of the bottom cylinder 8 and on the outside of the two support shafts 17. In order to facilitate the accurate dropping of fertilizer into the pit, a hopper 9 is fixed at the lower end of the bottom cylinder 8. In order to facilitate operation control and power supply, a power supply module 5 is provided at the center inside the base plate 1, and a control module 4 is provided at the upper end of one side of the base plate 1. All the above electrical components are electrically connected to the control module 4 and the power supply module 5. The existing power connection technology is disclosed and will not be described in detail here.

[0038] The mechanical transmission components provided in this utility model are all closed designs that can be opened for maintenance. According to the mechanical manual, as long as they are properly maintained, these mechanical transmission components can normally realize the transmission motion claimed above.

[0039] The automatic hole fertilization combination tool provided by this utility model is used as follows: After the base plate 1 is stably supported above the hole to be fertilized by the balancing mechanism 3, the automatic feeder 6 is started to facilitate the quantitative delivery of fertilizer in the storage bin 2 to the inside of the bottom cylinder 8 through the conveying pipe 7 and located between the top plate 16 and the two switch plates 18. At this time, the weight of the fertilizer is not enough to open the two switch plates 18.

[0040] Then, the starting reduction motor 20 is controlled to drive the second flat gear 21 to rotate. The meshing of the second flat gear 21 with the first flat gear 19 drives the hollow screw barrel 10 to rotate. With the threaded connection between the screw 12 and the hollow screw barrel 10, and the sliding guidance of the T-shaped lifting seat 13, the limiting guide rod 14 and the guide frame 11, the T-shaped lifting seat 13 is easily driven to move down, so that the pressure rod 15 moves down through the capping plate 16. Then, the two pressure rods 15 push open the two switch plates 18, so that the switch plates 18 flip open with the support shaft 17 as the axis, so that the fertilizer falls accurately into the pit through the hopper 9 to complete the fertilization. After the T-shaped lifting seat 13 is reset, the elasticity of the torsion spring 22 is used to drive the two support shafts 17 to rotate and reset, so that the two switch plates 18 close again to prepare for the next hole application.
