Description

Technical Field

[0001] The utility model relates to the technical field of soybean planting, in particular to a punching device for soybean planting. Background Art

[0002] Soybean is one of China's important food crops with a 5,000-year cultivation history. It was called "shu" in ancient times. Northeast China is the main producing area. It is a crop whose seeds are rich in plant protein. Soybean is most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. Because the soybean seed coat is thick, it needs to be germinated in advance when planted to ensure that the seedlings emerge in blocks and in an orderly manner.

[0003] When sowing soybeans, holes need to be drilled. Existing drilling equipment is usually a hollow iron cylinder, which is pressed hard into the soil to perform the drilling operation. Since only a single hole can be drilled each time, the drilling efficiency is low, and after the hole is drilled, some soil will be blocked inside the iron cylinder. The soil needs to be pushed out before it can be used again, which greatly increases the labor intensity of personnel. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problem that only a single hole can be punched each time, resulting in low drilling efficiency, and part of the soil will be blocked inside the iron cylinder after the hole is punched, and the soil needs to be pushed out before it can continue to be used, which greatly increases the labor intensity of the personnel, and a punching device for soybean planting is proposed to solve the problem.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a punching device for soybean planting, comprising a base and a fixed bin, a pulley is fixedly installed on the bottom of the base, two fixed plates are fixedly connected to the top of the base, the inner ends of the two fixed plates are fixedly connected to a carrier frame, a push rod is fixedly connected to the surface of the fixed plate, a cavity is opened inside the fixed bin, a baffle is fixedly connected to the top of the fixed bin, a movable rod is movably installed on the inner wall of the cavity, a cam and a driven bevel gear are respectively fixedly connected to the surface of the movable rod, a spring is fixedly installed on the bottom of the cavity, a mounting plate is provided inside the cavity, a fixing cylinder is fixedly connected to the bottom of the mounting plate, and a drill cylinder is movably installed on the bottom of the fixed cylinder.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a punching device for soybean planting, comprising a base 1 and a fixed bin 2, a pulley 11 is fixedly installed at the bottom of the base 1, two fixed plates 12 are fixedly connected to the top of the base 1, the inner ends of the two fixed plates 12 are fixedly connected to a carrier frame 13, a push rod 14 is fixedly connected to the surface of the fixed plate 12, a cavity 201 is opened inside the fixed bin 2, a baffle 21 is fixedly connected to the top of the fixed bin 2, a movable rod 22 is movably installed on the inner wall of the cavity 201, and a cam 23 and a driven bevel gear 2 are fixedly connected to the surface of the movable rod 22 respectively. 4. A spring 25 is fixedly installed at the bottom of the cavity 201. A mounting plate 4 is provided inside the cavity 201. A fixing cylinder 41 is fixedly connected to the bottom of the mounting plate 4. A drill cylinder 5 is movably installed at the bottom of the fixing cylinder 41. A driving motor 3 is fixedly installed inside the blocking cover 21. A connecting rod 31 is fixedly connected to the output end of the driving motor 3. A transmission bevel gear 32 is fixedly installed on the surface of the connecting rod 31. The side surface of the transmission bevel gear 32 is engaged with the side surface of the driven bevel gear 24. Therefore, the bottom of the mounting plate 4 is fixedly connected to the top of the spring 25, and the fixing cylinder 41 movably runs through the bottom end of the cavity 201.

[0024] In this embodiment, the drill tube 5 is installed at the bottom of the fixed tube 41, and then the push rod 14 is pushed to push the fixed bin 2 to the specified position, and the driving motor 3 is started to drive the connecting rod 31 and the transmission bevel gear 32 to rotate, and the transmission bevel gear 32 is meshed with the driven bevel gear 24, so that the movable rod 22 and the cam 23 rotate accordingly, and the cam 23 is squeezed when rotating. The mounting plate 4 is squeezed and moves vertically downward, and the spring 25 is compressed. At this time, the fixed tube 41 drives the drill tube 5 to move vertically downward into the soil to perform a drilling operation on the land, and when the movable rod 22 drives the cam 23 to rotate continuously, the spring 25 rebounds to reset the mounting plate 4, and the soil is stored in the drill tube 5 and brought upward to complete the drilling operation. A plurality of fixed tubes 41 are installed at the bottom of the mounting plate 4, and drill tubes 5 are installed at the bottom of the plurality of fixed tubes 41. Multiple holes can be drilled at one time, thereby improving the drilling efficiency. Example

[0025] like Figure 1-Figure 5 As shown, the bottom of the fixed cylinder 41 is fixedly connected with a threaded sleeve 42, the interior of the threaded sleeve 42 is a hollow structure, the interior of the drill cylinder 5 is a hollow structure, a threaded groove 501 is provided at the top of the inner wall of the drill cylinder 5, the inner wall of the drill cylinder 5 is threadedly connected to the surface of the threaded sleeve 42, and the top of the inner part of the fixed cylinder 41 is fixedly installed with a cylinder 6, the output shaft of the cylinder 6 is fixedly connected with a push plate 61, and the side of the push plate 61 is in contact with the inner wall of the fixed cylinder 41.

[0026] In this embodiment, when the drill barrel 5 needs to be replaced, the drill barrel 5 is rotated to be removed from the surface of the threaded sleeve 42, and the drill barrel 5 can be separated from the fixed barrel 41, which is convenient for disassembly and installation of the drill barrel 5. When the number of holes drilled in a single time needs to be adjusted, the drill barrels 5 of the corresponding number are installed to control the number of holes drilled in a single time, thereby improving the applicability of the device. When the drill barrel 5 brings out the soil, the soil accumulates inside the drill barrel 5. The cylinder 6 is started to extend the push plate 61 downward, and the soil inside the drill barrel 5 can be pushed out.

[0027] The working principle of this embodiment is as follows: pushing the push rod 14 pushes the fixed bin 2 to the specified position, starting the drive motor 3 to drive the transmission bevel gear 32 to rotate, and the transmission bevel gear 32 and the driven bevel gear 24 are meshed with each other, so that the cam 23 follows the rotation to squeeze the mounting plate 4 downward, and compresses the spring 25. At this time, the fixed tube 41 drives the drill tube 5 to descend for drilling, and when the movable rod 22 drives the cam 23 to rotate continuously, the spring 25 rebounds to reset the mounting plate 4, and the soil is stored inside the drill tube 5 and brought upward. When the drill tube 5 rises to the ground, the cylinder 6 is started to extend the push plate 61 downward and push out the soil inside the drill tube 5, which is convenient for cleaning the drill tube 5, thereby reducing the labor intensity of personnel.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
