Description

Technical Field

[0001] The utility model relates to the technical field of seed shelling equipment, in particular to a material pushing and cutting mechanism for a seed shelling machine. Background Art

[0002] Seed shelling is one of the necessary conditions for seed germination. When seeds germinate, the shell needs to be broken so that the embryo and even the roots can stretch out to absorb water, nutrients and other substances needed for growth. If the seed shell is too hard, it will seriously affect the germination rate and growth development, thereby reducing the yield and quality. Therefore, mechanical shelling is usually used to break the seeds. This method can overcome the problem of the seed shell being too hard and can increase the germination rate and growth rate.

[0003] The existing seed shelling machine can refer to a Chinese utility model patent with patent application number CN202320790674.0, which discloses a shelling machine for seed processing, including a box body, a motor is fixedly arranged on the right side of the box body, the rotating shaft of the motor is fixedly connected to one end of the rotating shaft, and a shelling roller is fixedly connected to the outside of the rotating shaft, and slots are arranged on the left and right ends of the box body, and fixed blocks are fixedly connected to the upper and lower sides of the middle part of the left and right ends of the box body, and the front and rear ends of the inner side of the fixed block are fixedly connected to one end of the spring, and the other end of the spring is respectively fixedly connected to the front and rear ends of the upper and lower sides of the sealing plate, and the two ends of the rotating shaft are respectively rotatably connected to the middle part of the inner side of the sealing plate. This technology pushes and compresses the spring through the sealing plate, thereby driving the motor, the rotating shaft and the shelling roller to move up and down, so that the distance between the crushing roller and the bottom end of the box body is increased or decreased, so that seeds of different sizes can be shelled.

[0004] However, in the above structure, the unloading process requires an additional blower to blow air into the box. The next loading can only be carried out after the debris in the box is blown out. There are many steps and the structural complexity is increased. Moreover, after the shells are crushed, the broken shells and seeds are mixed together and cannot be separated quickly and effectively. When the debris is blown out of the box by blowing, the seeds may be blown out together. The debris needs to be screened again, which not only increases labor costs but also affects efficiency.
