Soil crushing device for agricultural research

Abstract

The invention discloses a soil crushing device for agricultural research, belongs to the technical field of agricultural experiments, and solves the problem of small contact area between a crushing rod and soil in an existing device. The device is technically characterized in that the device is characterized by comprising a base and a stirring cavity. A plurality of supporting legs used for supporting the base are fixedly installed at the bottom of the base; the stirring cavity is formed in the upper portion of the base; a driving assembly is arranged at the left side of the stirring cavity;a stirring assembly is arranged in the stirring cavity; the stirring assembly and the driving assembly are fixedly connected through a shaft coupler; and the driving assembly comprises a stirring motor and a storage battery, wherein the storage battery is arranged at the bottom of the stirring motor and electrically connected with the stirring motor through a wire. According to the embodiment of the invention, a hammer crushing assembly and a second crushing knife are arranged, so that sufficient refining of soil in the middle of the stirring cavity is guaranteed; meanwhile, a striking block is arranged, so that blocky soil in the stirring cavity can be crushed, and the fineness of the soil is guaranteed; and the soil crushing device further has a soil remediation function.

Description

technical field [0001] The invention relates to the technical field of agricultural experiments, in particular to a soil crushing device for agricultural research. Background technique [0002] The crushing of soil is one of the important links in the industrial seedling raising process. The use of soil crushers greatly reduces the input of manpower, saves time, labor and improves the efficiency of crushing soil. At present, when cultivating crops in agricultural laboratories, large pieces of soil need to be crushed The soil is broken into fine soil, and in the existing agricultural laboratory, there is no dedicated device for crushing soil. [0003] Chinese patent CN205105537U discloses an agricultural soil crusher for laboratory use, including a frame, rollers, a controller, a guide cylinder, a hydraulic cylinder, a discharge port, a crushing cylinder, a crushing rod, a felt plate, a feed port, and a crushing plate , the feed inlet, the crushing cylinder, and the discharg...

Problems solved by technology

[0003] Chinese patent CN205105537U discloses an agricultural soil crusher for laboratory use, including a frame, rollers, a controller, a guide cylinder, a hydraulic cylinder, a discharge port, a crushing cylinder, a crushing rod, a felt plate, a feed port, and a crushing plate , the feed inlet, the crushing cylinder, and the discharge outlet are connected in sequence, and they are all set on the frame. There are also felt plates and guide cylinders on the frame. The upper right of the crushing cylinder is the guide cylinder, and the lower left of the crushing cylinder is set. There is a felt plate, and a hydraulic cylinder is set in the guide cylinder; but the contact area between the crushing rod and the soil in this device is small, resulting in low soil crushing efficiency, so we propose a soil crushing device for agricultural research
