Description

Technical Field

[0001] The utility model relates to the technical field of soil covering equipment, in particular to a soil covering equipment for soybean breeding experiments. Background Art

[0002] Soybeans, commonly known as yellow soybeans, are native to China and are cultivated throughout China and also widely cultivated around the world. Soybeans are one of the important food crops in China with a cultivation history of five thousand years. They were anciently called shu. The main producing area in China is Northeast China. It is a crop whose seeds are rich in plant protein. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. Soybean dregs or coarsely ground soybeans are also commonly used in livestock feed. In order to improve the quality of soybeans, breeding experiments on soybeans are required.

[0003] After soybean planting is completed, it is necessary to cover the planting rows with soil. Currently, generally, personnel use a handheld double-disc soil covering device for soil covering. During operation, the personnel hold the long rod of the double-disc soil covering device, place the two double discs on both sides of the planting row respectively, and then the personnel pull the long rod along the planting row to make the two discs roll along the planting row, and at the same time push the soil piles on both sides of the planting row into the planting row for soil covering. However, since the distance between the two discs of the existing double-disc soil covering device is not adjustable, its applicability is poor when facing planting rows of different widths.

[0004] Therefore, how to design a soil covering equipment for soybean breeding experiments has become a problem that we need to solve currently. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides the following technical solution: a soil covering equipment for soybean breeding experiments, including a long rod, a connecting seat, a support seat and discs. The connecting seat is hinged at the tail end of the long rod. The support seat is slidably sleeved at both ends of the connecting seat. The discs are rotatably installed on one side of the support seat.

[0006] A threaded pipe is rotatably installed inside the connecting seat. A driving component is connected to the middle of the threaded pipe. Threaded rods are threadedly connected to both ends of the threaded pipe. The threaded rods are fixedly connected to the support seat.

[0007] As an improvement of the above technical solution, the long rod includes a first rod body and a second rod body. The first rod body is slidably connected inside the second rod body. A number of connecting grooves are arranged at fixed intervals on the surface of the first rod body. A connecting bolt adapted to the connecting groove is threadedly connected to one side of the second rod body.

[0008] As an improvement of the above technical solution, an anti-slip sleeve is fixedly sleeved at the end of the first rod body. Anti-slip lines are arranged on the surface of the anti-slip sleeve.

[0009] As an improvement of the above technical solution, an articulated seat is fixedly connected to the end of the second rod body. The articulated seat is articulated with the connecting seat. A plurality of positioning holes distributed around the hinge axis are formed on the surface of the articulated seat. A positioning bolt is inserted into one side of the positioning hole, and a threaded groove adapted to the positioning bolt is formed on one side of the connecting seat.

[0010] As an improvement of the above technical solution, the driving assembly includes a handle, a worm and a worm gear. The handle is fixedly installed at the upper end of the worm. The worm is rotatably installed in the connecting seat. The worm gear is fixedly sleeved on the threaded tube and meshes with the worm.

[0011] As an improvement of the above technical solution, a groove is formed at the top of the connecting seat, and the handle is embedded in the groove.

[0012] As an improvement of the above technical solution, a cover plate for covering the groove is hinged to the top of the connecting seat.

[0013] The beneficial effects of the present utility model:

[0014] By setting the threaded tube, the driving assembly and the threaded rod, the present utility model can rotate the worm by using the handle, so that the worm drives the worm gear to rotate, the worm gear drives the threaded tube to rotate, the threaded tube drives the threaded rod to slide along the threaded tube, and the threaded rod drives the support seat to slide along the connecting seat, thereby adjusting the distance between the two discs to adapt to planting rows of different widths;

[0015] By setting the first rod body, the second rod body, the connecting groove and the connecting bolt, the present utility model can unscrew the connecting bolt to make the first rod body and the second rod body slide relative to each other, and then screw the connecting bolt into different connecting grooves to adjust the length of the long rod, which is convenient for people of different heights to use;

[0016] By setting the articulated seat, the positioning hole, the positioning bolt and the threaded groove, during use, the long rod can rotate relative to the connecting seat through the articulated seat. Inserting the positioning bolt into different positioning holes can adjust the angle of the long rod, thereby adjusting the angle when the person pulls the long rod, which is convenient to meet different use requirements.
