Abstract

The invention relates to the design of crushers and can be used for processing industrial waste from the timber, woodworking, rubber and chemical industries. The goal is to increase reliability. The crusher includes a housing 1 in which shafts 2 are mounted for rotation by an individual drive. On the shafts 2 mounted disks 7 with cutting knives. The disks are made with double-sided radial slots 8, which allows you to set any form of the cutting line forming knife depending on the processed material and keep this form constant during the operation of the crusher. The disks 7 are connected to the shaft 2 through the clutch of the limiting moment. 8 il.

Description

The invention relates to the field of mechanical engineering and can be used in forestry, woodworking and other industries in the field of crushing industrial waste.

The purpose of the invention is to increase reliability.

FIG. 1 shows a roll crusher, top view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a cross-section of the FIG. four; in fig. 6 is a view of D in FIG. four; in fig. 7 - setting the forming line of the two rolls along a triangle with an angle towards each other (a wedge); in fig. 8 - the same, along a broken line with angles towards each Friend.

The crusher consists of a housing 1 in which shafts 2 are rotatably mounted on support bearings for rotation from an individual drive consisting of an electric motor 3, a clutch 4, a gearbox 5, a clutch 6 on each shaft 2 are mounted disks 7 with cutting elements, made with double-sided radial splines 8, interacting with a number of splines of other discs 7, 3 located. 3, suits can also be connected with the help of pins, embedded keys, balls.

At the opposite end of the drive shaft 2, there is a distance bushing 9 with a bearing 10, made with radial end splines 11, interacting with the splines of the bushing 12, which is mounted on the spline end of the shaft 2 and spring-loaded with a disc spring 13 using a pressure washer 14, end washer 15 and bolt 16. The whole mechanism is closed by a casing 17, inside which a limit switch 18 is installed, the roller of which interacts with the collar of the sleeve 12. A hopper 19 is installed above the crusher body 1.

The radial slots 8 of the discs 7 are made with the angles of inclination of the side faces 80-90 °.

The radial slots of 11 sleeves 9 and 12 are made with the angles of inclination of the side faces 45-50 °.

Crusher works as follows.

Before starting work, it is necessary to install the cutting elements on the shafts 2 so that the forming cutting line of the knives corresponds to the material being crushed in order to achieve greater productivity and the required quality of grinding.

The setting of the cutting line forming line is made as follows. The bolt 16 is loosened, the spring 13 is released, the sleeve 12, together with the spacer sleeve 9 and the bearing 10, is displaced by the size of the tongue 8 of the discs 7, ensuring free rotation of the latter.

By turning the discs 7 on the shaft 2, the required forming line of the knives is established, the two forms of which with a wedge and broken line are shown in FIG. 7 and 8. Other forms are possible forming a cutting line of knives.

Then, the disks 7 are shifted so that the end splines 8 are engaged, the bolt 16 is tightened, clamping the spring 13 by a certain working force.

The hopper 19 is loaded with waste and the rotation of the shafts 2 is turned on. The crushing of the waste is carried out by cutting elements that capture objects, such as branches, knots and they are crushed with a counter-movement.

In the case of falling into the cutting elements of solid, indestructible objects (stones,

pieces of metal, etc.), the latter are stopped (jammed), and since the drive power is calculated for this critical case, the shafts 2 continue to rotate together with the sleeves 9 and 12. As the discs 7 are 100 t, and the shafts 2 rotate, An axial force arises on the slots 11, which compresses the spring 13, acts by the collar of the sleeve 12 on the roller of the limit switch 18, which turns off the drive of rotation by the shaft 2, the electric motor 3.

The non-crushable item is removed and the crusher is put into operation. Moreover, the shape of the predetermined cutting line has not changed, since the bevel angle of the splines 8 of the discs 7 is much larger than that of the slits of the 11 sleeves 9 and 12, therefore the discs 7 do not turn.

Such a crusher design has a wide range of applications in the crushing of various industrial wastes, due to the possibility of installing any form of the forming cutting line of knives, and during operation the form forming retains
