An energy-saving soil crushing device suitable for crop planting research

Abstract

The invention discloses an energy-saving soil crushing device suitable for crop planting research, which comprises a machine body, a crushing chamber, a rolling chamber, a heating chamber and a screening chamber. The motor is installed, the motor is a biaxial motor, and the left end of the motor is fixedly connected to the rotating shaft; A screen, the first slide is set on the outside of the first screen; a screening chamber is provided at the lower part of the rolling chamber, a second screen is installed in the screening chamber, and a compression spring is fixedly connected to the right end of the second screen; The invention has reasonable design, high energy saving and high efficiency, can fully crush and screen frozen soil, and simultaneously uses one motor to complete multiple programs, thus saving a large amount of energy.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an energy-saving soil crushing device suitable for crop planting research. Background technique [0002] Agriculture in the broad sense refers to the five industrial forms including planting, forestry, animal husbandry, fishery, and sideline industry; agriculture in the narrow sense refers to [0003] crop farming. Including the production activities of crops such as food crops, commercial crops, feed crops and green manure. Different crops will be planted according to different seasons. When the crops are replanted, it is necessary to crush and loosen the soil in the planting area of ​​the farmland to facilitate the growth of the crops, especially for the planting of saplings and vegetable seedlings. The loosening of the soil is conducive to rooting. In the prior art, when the farmland is crushed: it is necessary to plow the soil first, and then rotate it severa...

AI Technical Summary

Problems solved by technology

In the prior art, when the farmland is crushed: it is necessary to plow the soil first, and then rotate it several times to meet the requirements of the crushed soil. It will pulverize all the surface soil of the entire field, consume a lot of energy, and waste a lot of time; In the process of planting crops, not every area will be planted. At present, in my country's Qinghai-Tibet Plateau, Northeast China, Xiaoxing'an Mountains and other areas, because they are located in severe cold areas, special permafrost has formed; when constructing in these areas, It will be affected by the low temperature in winter; under normal circumstances, surface covering measures are used to protect soil materials in winter construction, such as covering the surface of building surfaces or excavation surfaces with thermal insulation materials; surface covering measures can only alleviate the degree of freezing, but cannot fundamentally solve the problem. Soil materials are frozen. Therefore, the entire farmland is completely crushed. The efficiency of crushing soil is low, the soil utilization rate is low, and a large amount of economic losses are caused.

[0004] At present, when agricultural planting laboratories study and cultivate crops, large pieces of soil need to be broken into fine soil. In the existing agricultural planting laboratories, there is no dedicated device for crushing soil. Many crushing devices are relatively large and do not It is suitable for laboratory research work, and the crushing capacity of small soil crushers is relatively small, and the effect of crushing soil is poor. Therefore, it is necessary to develop a high-efficiency and good crushing effect of soil crushers for agricultural planting laboratories.
