detailed description

Example 1

The cylinder type tooth plate breaking coal discharging machine comprises a box body 1. The left end of the box body 1 is provided with an inclined feeding chute 2, the bottom of the box body 1 is fixed with a sieve plate 5, and the bottom side of the screen plate 5 and the feeding chute 2 Docked. The upper portion of the sieve plate 5 is provided with a cylinder tooth plate 4 and a driving device 3 for allowing the cylinder tooth plate 4 to move in a circular motion. As shown in FIG. 2, a motor 301 is disposed on each side of the cylinder tooth plate 4 through the fluid coupling 302 and the speed reducer 303 to drive the active eccentric 304. The two active eccentric wheels 304 drive the four passive eccentric wheels 305 such that the cylinder tooth plates 4 remain parallel and integrally circular, with a radius of circumferential motion of 400 mm. The cylinder tooth plate 4 is evenly distributed with piston cylinders 401 which are arranged in six rows and four rows in a row, the row spacing is 200 mm, the stroke of the piston rod 403 is 400 mm, and the head of the piston rod 403 of the piston cylinder 401 The taper is provided with a wear-resistant material at the tapered tip to increase the wear resistance and splitting action of the head, and the wear-resistant material is separated from the piston rod to facilitate replacement after wear. The sieve plates 5 are uniformly arranged horizontally to form a uniform sieve slit having a size of 150 mm. The sieve plate 5 is at an intermediate position below the two horizontal piston cylinders 401, and each horizontal piston rod 403 is facing a screen slit, and the head of the piston rod 403 is crushed. The length of the sieve plate 5 is 200 mm longer than the radial running path of the cylinder tooth plate 4.

In use, the air pressure of the piston cylinder 401 on the cylinder plate 4 is adjusted first. Due to The hardness of lump coal and vermiculite differs greatly. When the air pressure is adjusted to the conical top of the piston rod 403 to the carbon block, it can be broken. When the rock is pushed up to the vermiculite, the piston rod 403 is retracted, so that the crushing has selectivity. The bulk material of the coal mine enters the sieve plate 5 at the bottom of the tank body 1 from the feed chute 2, and the two active eccentric wheels 304 drive the four passive eccentric wheels 305, thereby driving the cylinder tooth plate 4 to be parallel to the periodic circumference of the sieve plate 5. During the movement and movement, the cylinder tooth plate 4 is horizontally displaced, and is kept parallel with the sieve plate 5, and the cylinder tooth plate 4 is periodically approached and away from the sieve plate 5 to achieve the functions of crushing coal, transporting materials and sieving. . When the cylinder tooth plate 4 makes a circular motion to reach the lowest position; the head of the piston rod 403 protrudes from the lowest position that the cylinder 402 can reach and the distance from the sieve plate 5 is 50 mm to increase the upper limit of the crushing granularity. After the lump coal is broken, it enters the sieve through the sieve joint, and the large vermiculite remains on the sieve plate 5, and is separated from the right side of the sieve plate 5 by the operation of the piston rod 403. The invention has the advantages of less investment, saving power, adjustable crushing hardness, eliminating coal with less coal, no need for human beings, small size, easy arrangement, sturdiness and durability, and low maintenance, and is a new effective alternative to manual selection.
