Drum type mechanical shell breaking machine for hard seeds

Abstract

The invention discloses a drum type mechanical shell breaking machine for hard seeds. The drum type mechanical shell breaking machine for hard seeds comprises a frame (1), an outer shell (2), a motor(3), a vibrating screen (4) and a grinding mechanism (5); the outer shell (2) is fixedly mounted on the frame (1), the motor (3) is mounted at one side of the outer shell (2), the vibrating screen (4)is mounted at the upper side of the internal of the outer shell (2), and the grinding mechanism (5) is located below the vibrating screen (4); and the top of the outer shell (2) is provided with a feeding opening (7), and the lower part of the outer shell (2) is provided with a discharging opening (8). The drum type mechanical shell breaking machine for hard seeds has the advantages of reasonablestructural design, convenience in operation, high shell breaking efficiency for alfalfa and other hard seeds, improvement of the germination rate of the hard seeds, increase of the yield of alfalfa,and strong practicability.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a drum type hard seed mechanical shell breaker. Background technique [0002] Alfalfa is a perennial leguminous forage, which can obtain considerable grass yield in the second year after planting, and can be harvested 3 to 7 times a year. It is a high-quality forage used by various livestock. It has a long history of planting in my country and has been It's called the "King of Grass". Along with the continuous development of the commodity economy and the adjustment of the planting structure, the planting area of ​​alfalfa has been continuously expanding, and its characteristics such as strong environmental adaptability have gradually emerged. However, alfalfa seeds have hard problems, which make them difficult to absorb water and have difficulty in aerobic respiration. If they are directly sown without treatment or improper treatment methods, there will be low germination rate or no ger...

AI Technical Summary

Problems solved by technology

However, alfalfa seeds have hard problems, which make them difficult to absorb water and have difficulty in aerobic respiration. If they are directly sown without treatment or improper treatment methods, there will be low germination rate or no germination after sowing, resulting in lack of seedlings and broken ridges, reducing forage Yield, which seriously affects the utilization of alfalfa seeds in the same year, and has a serious impact on the planting and production of alfalfa

[0003] Therefore, before planting, it is necessary to perform shell breaking treatment. Among the existing methods, there are two common methods: warm soaking seeds and acid-base solution treatment. These two treatment methods use thermal and chemical principles to contact and harden alfalfa seeds respectively. , but they all cause damage to the germ of the seeds, and the particles are small, so they cannot be conveniently and effectively used in practical production, especially when large-scale planting requires batch processing of seeds, which is more difficult to operate
