Simple soil crusher

Abstract

The invention discloses a simple soil crusher. The simple soil crusher comprises a frame, an enclosure, a motor, a belt pulley, a feeding hole, a crushing device, a screen drum, a discharge hole and an impurity outlet; and the screen drum full of meshes is arranged on the frame, the screen drum is positioned in the enclosure and encircles a central shaft arranged obliquely, the clearance between a blade and the screen drum is variable, and the meshes on the screen drum are distributed with big, small and medium sizes. The motor transmits power to the belt pulley to drive the central shaft to rotate; and the central shaft drives a cutter head to rotate, soil blocks are crushed under the actions of striking, collision and friction of cutters uniformly distributed on the cutter head, and thecrushed soil reaches the discharge hole through a screen. Because the whole crushing chamber is arranged with a certain inclination angle, un-crushed big impurities such as soil blocks, stones and the like can roll to the impurity outlet at the tail end of the crushing chamber and fall. The simple soil crusher has simple structure, reduces idle consumption, has low power consumption and high production efficiency, and is convenient for detachment and maintenance and convenient to use.

Description

technical field [0001] The patent of the present invention relates to a soil crusher, in particular to a soil crusher with simple structure with the functions of crushing and sieving soil. Background technique [0002] Rice seedlings, flower beds, greenhouses and greenhouses require a lot of fine soil. The fine soil must be crushed and screened. [0003] One of the currently used soil crushers on the market is that the soil crusher and the screening machine are separate equipment. The soil crusher is used to crush soil clods; the screening machine is used to screen fine soil, which increases the workload of soil transportation. The labor intensity of the workers is high; and the efficiency is low and the cost is high. There is also a soil crusher and a soil sifter as one, and the equipment is relatively complicated and the price is high. Contents of the invention [0004] The object of the present invention is to provide a simple soil crusher, which organically combines...
