Extrusion soil breaker

Abstract

The invention discloses an extrusion soil breaker, which comprises a frame, a left wallboard, a right wallboard, a screw shaft, a casing and a pulley. The left wallboard and the right wallboard are disposed on the frame, the screw shaft supported via bearing blocks penetrates through the left wallboard and the right wallboard, the casing with a feeding port and a discharging port is fixedly connected to the left wallboard and the right wallboard, the pulley disposed on the screw shaft is driven by a motor, breaking claws are evenly distributed on a screw vane (2) on the screw shaft (3) inside the casing (11), a cylindrical screen (10) connected to the left and right wallboards (8) is radially arranged between the screw vane and the casing, a pressure disc (9) with evenly and peripherally distributed pressure claws (18) is sleeved on the screw shaft inside the cylindrical screen, and the pressure disc and the left wallboard adjacent to the same are provided with anti-rotating holes (19 and 20) respectively and correspondingly connected through anti-rotating pins (21). Impurities and bricks in soil can be effectively separated from the soil while soil breaking and screening functions are achieved by using the extrusion soil breaker, and the extrusion soil breaker is simple and compact in structure, convenient in disassembly and maintenance, low in cost, low in vibration, low in noise, low in power consumption and widely applicable.

Description

technical field [0001] The patent of the invention relates to an extruding soil clod crusher, which belongs to the technical field of mechanical equipment. Background technique [0002] At present, rice seedling raising, flower gardens, greenhouse and greenhouse seedling raising, and agricultural scientific research experiments require a large amount of crushed soil of different specifications. Generally, soil clods are first crushed by a soil clod crusher, and then screened by a screening machine. It is not only labor-intensive and time-consuming, but also has high cost and high labor intensity. Though the equipment that a kind of clod breaker and soil sieving machine are integrated is arranged now, its not only equipment is comparatively complicated, and price is higher, and vibration, noise are serious, dust is bigger, affects worker's health. Contents of the invention [0003] The object of the present invention is to provide an extrusion type soil block crusher which...
