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.

Example Embodiment

[0014] Such as Figure 1-5 As shown, an squeezing soil crusher includes a frame, left and right wall panels arranged on the frame, auger shafts that pass through the left and right wall panels and are supported by bearing seats, and fixedly connected to the left and right wall panels. A casing with inlet and outlet ports and a belt wheel on the auger shaft driven by a motor. In the casing 11, the auger blades 2 on the auger shaft 3 are evenly distributed with crushing claws, and a screen tube 10 connected to the left and right wall panels 8 is arranged between the auger blades and the radial direction of the casing. The sieve cylinder is composed of two semicircular thick steel plates, and the sieve cylinder composed of the thick steel plates is provided with sieve holes with the same diameter. The gap between the auger blades and the screen cylinder is the same. The screw shaft in the screen cylinder is fitted with a pressure plate 9 with pressure claws 18 evenly distributed in the circumferential direction. The pressure plate and the anti-rotation holes 19 and 20 respectively opened on the adjacent left wall plate are correspondingly connected through the anti-rotation pin 21, so that the pressure plate is only It can move along the axis of the auger without rotating with the auger shaft.
[0015] The pressure plate 9 and the adjusting nut 6 installed on the outer auger shaft 3 of the left wall plate are connected by a spring 7 sleeved on the auger shaft. The proper pressure of the spring on the pressure plate can be maintained by adjusting the adjusting nut 6, It can be used to adjust the crushing pressure according to the hardness of the soil block, and it can also be used to prevent overload protection. The spring 7 is a strong spring.
[0016] The pressure plate 9 and the screen tube 10 on the side of the left wall panel adjacent to the pressure plate 9 are provided with a defective product discharge port 13 so as to push the hard materials and sundries that have not been broken during the extrusion process of the auger Go to the defective product outlet and discharge from the defective product outlet.
[0017] Its working process: start the motor 15, the motor drives the pulley 14 fixed on the auger shaft to drive the auger shaft to rotate, the soil block directly enters the sieve barrel through the feed port 12, and is pushed by the auger and the claws, the sieve cylinder, Under the combined extrusion and shearing action of the strong spring, it moves in a spiral curve in the direction of the discharge port and is gradually broken, and flows from the perforations of the screen cylinder to the finished product discharge port 1. The hard materials and debris that are not broken are It is pushed to the end of the sieve cylinder and discharged from the defective product discharge port 13, so as to achieve the dual functions of effectively separating impurities in the soil, bricks and soil, and crushing and screening the soil.
