Abstract

The invention relates to a technique for mechanically separating a bulk material and makes it possible to increase the reliability of the operation of a separator key. For this, on the base 1, the keys are inclined at an acute angle in the direction of movement of the screened material guide grooves (NP) 6 with parallel walls. Under each NP 6, protrusions 7 with a threaded hole 8 are located. In NP 6, the bodies of cutting elements (RE) 9 are arranged to move along them, the shape of which corresponds to the shape of NP 6. In each threaded hole 8, a shaped plug (AF) 12 is installed, which is connected at one end to the elastic element 11. Its second end is connected to the ER 9. In this case, the ER 9 are located with the same spacing on the base 1, having protrusions 2 in the form of bearing housings 3, and are held in the NP 6 with a strong thread. One end of the thread is connected to the ER 9, and the other - with the FP 12. Changing the position of the FP 12 in the hole 8 of the protrusions 7 controls the rigidity of the elastic element 11. The inclination of the NP 6 at an acute angle provides the least resistance when lowering the RE 9 in them. Non-continuous placement of the ER 9 along the length of the base 1 hinders the movement of the unextended material along the keys and increases its interaction with the base 1. At the same time, the large lumps of the material are loosened by the teeth of the ER 9. 2 hp f-ly, 7 ill.

Description

1

The invention relates to a technique for mechanically separating bulk material, in particular, to keyboard type separators, and can be used in the treatment of highland and lowland peat.

The purpose of the invention is to increase the reliability of the operation of the separator key.

FIG. 1 shows a key assembly, side view; in fig. 2 - the same, top view; in fig. 3 - base, side view; in fig. 4 - insert installation, side view; in fig. 5 - insert, longitudinal section; in fig. 6 shows section A-A in FIG. five; in fig. 7 - insert in the lowered position, side view (longitudinal section).

The bulk material separator key includes a base 1, at both ends of which protrusions 2 are made, made in the form of bearing housings 3, to which covers 5 are attached by means of screws 4 On the base 1, vertical guideways 6 with parallel walls and internal guide grooves 6 arranged obliquely at an acute angle, for example 45 °, in the direction of movement of the material. In the lower part of the base 1, protrusions 7 are made with a threaded hole 8 located under each groove. Cutting elements 9, made in the form of a housing with teeth and with a cylindrical socket 10 on the bottom end, are placed in the grooves 6. The body of the cutting elements is made in the form of a groove 6 (parallelogram in cross section). To keep the cutting elements 9 in the working position, the base is provided with elastic elements in the form of compression springs 11, one end of which is placed in the slot 10 of the cutting elements 9, and the other end abuts the shaped plug 12 with a hole 13 screwed into the hole 8 of the protrusion 7. Cutting element 9 is held in the groove 6 of the base 1 by a strong thread 14, one end of which is connected to element 9 and the other end to plug 12.

Key separator bulk materials works as follows.

Using crankshafts or eccentric bushings (not shown) mounted on the bearing housings of the projections 2 of the base 1, a circular motion is communicated to the key. Material is supplied to the keys, for example peat, which falls through the slots formed by the adjacent keys. Larger pieces of material falling on the base 1 are crushed, and the teeth of the cutting elements 9 are steamed and cut the peat pieces and cut through the long fibers. Unprocessing material (peat, stones, etc.) located on the keys moves in the direction of their movement to the place of discharge. At the same time, non-continuous placement of re

The moving elements 9 along the base 1 restrain the movement of the unsolicited material along the keys. The speed of movement of the material becomes smaller, and the duration of its interaction with the base 1 increases. The result is a more thorough loosening of large pieces of material, such as peat, and the separation of adhered material on stumps and other foreign objects, since it creates the possibility of rolling and sliding the unsolved material along the base 1 from one element 9 to another. and the subsequent transfer of this material by the teeth of two other adjacent lifting bases 1 into the next span of the base 1 between the cutting elements 9.

The stiffness of the springs 11 is chosen so as to withstand the forces of a large piece or other solid object, for example, weighing 10-20 kg or more. When interacting with a heavier object, the movement of which is difficult, for example, with a log element 9) is buried in the groove 6 flush with the base 1. This ensures the movement of the specified object due to the dynamic contact of the base 1 of the key with this object. Moreover, both one cutting element 9 and all key elements 9 that form the screening surface can be deepened. In this case, the element 9 slides in the guide groove 6, presses against the spring 11, which is compressed and goes into the groove 6 (see Fig. 7). When the element 9 is released from the action of the object, the spring 11 is unclamped, the element 9 rises and takes the initial working position. A durable thread 14 connected to the element 9 and the opening 13 of the plug 12 keeps the element 9 from falling out of the groove 6.

The cylindrical seat 10 of the element 9 and the shaped plug 12 fix the position of the spring 11. By changing the position of the plug 12 in the opening 8 of the projections 7, adjust the stiffness of the springs 11. The inclination of the guide grooves 6 at a 45 ° angle provides the least resistance when lowering the element 9 in the slots 6.
