Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figure 1-5 As shown, a roller pulverizer includes an inner roller 1 and an outer roller 2, the outer roller 2 is arranged outside the inner roller 1, the diameter of the inner roller 1 is equal to the inner diameter of the outer roller 2, and the inner roller 1 and the two ends of the outer roller shaft 2 are plugged together through the inner column pins 3 respectively, the two ends of the inner column pins 3 are respectively provided with outer column pins 7, and the outer roller shaft 2 is axially provided with at least three rows of openings 4, There are at least three openings 4 in each row, and each opening 4 is evenly distributed on the outer roller shaft 2. The cross section of the opening 4 along the radial direction of the outer roller shaft 2 is trapezoidal. Each opening 4 is provided with a cutter head 5, ...

Abstract

The invention discloses a roller shaft crusher and a mated tool bit thereof, belongs to the technical field of crushing devices, and solves the problem of influence on production by easy falling of the tool bit in the crushing process. The roller shaft crusher comprises an inner roller shaft and an outer roller shaft; the outer roller shaft is arranged at the external of the inner roller shaft; the two ends of the inner roller shaft and the outer roller shaft are inserted through inner cylinder pins; at least three rows of holes are formed in the axial direction of the outer roller shaft; toolbits are arranged in all the holes; and the upper ends of the tool bits penetrate out of the outer surfaces of the holes. The roller shaft crusher is divided into the inner roller shaft and the outerroller shaft; the tool bits penetrate out of the holes of the outer roller shaft; the tool bits are fixed through insertion of the inner roller shaft in the outer roller shaft; inner and outer rollers are fixed by outer cylinder pins; even if acute vibration occurs in the working process, the whole tool bits are fixed safely and reliably; and the roller shaft crusher is novel in structure and convenient to operate and maintain, prevents the phenomenon of collision of the tool bits during crushing, and greatly improves the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of pulverizing devices, and in particular relates to a roller pulverizer and a matching cutter head thereof. Background technique [0002] In the prior art, the cutter head of the roller shredder is mostly connected in a movable manner, and can be disassembled when a failure occurs, but the connection method is mostly bolt fastening. The roller shredder moves violently during the working process, and the bolts are easily shaken off. The cutter head will collide with other cutter heads. Even if the operator stays close to each other and stops in time when he hears abnormal noise, the cutter head will be "knocked off" or damaged during maintenance. Due to the high hardness of the matching cutter head, the cost is high. , the production cost is also very high, and the frequency of regular maintenance is high. When the construction period is tight and continuous production is encountered, the machine must be shu...
