(54) THE CRUSHER KSLMS

Claims (2)

The invention retracts to a device for (shredding materials and can be applied in the agricultural and fossil industry sectors. A feed chopper is known, including supplying the loading and loading necks or the horizontal xpus, with a drum with knives and a deck with counter holes, which are located in it, and equipped with a chopper, and with a non-woofer shell. at the same time, the knives and cutting elements are made in truncated pyramid, the front and rear edges of which are in the form of equipotent trapeziums, and the deck is installed in the housing with the possibility of moving in p Adial direction Shi Z. The disadvantage of such a device is averaged in the absence of equal size of the material grinding and low device productivity. The closest technical solution to the proposed is a chopper feed, including a feed hopper, at the bottom of which a feed window is made, fixed to a comb, crushing chamber with a hammer rotor, discharge pipe 23. The disadvantage of this device. & a lot of energy and lack of efficiency of the grinding process. The purpose of the invention is to reduce energy consumption, increase the efficiency of the grinding process. This goal is achieved by the fact that, in the feed chopper, which includes the splint hopper, there is a power supply window in the bottom, a stationary guard against the comb, a crushing chamber with a hammer rotor, a discharge nozzle, the rotor is equipped with cutting plates installed alternately with the monitors located along the helix , and in the crushing chamber, under the cutting comb, an additional counterblowing comb is mounted with the possibility of rotation, ("the working elements of which are made of trapezoidal shape, and the unloading The nozzle is made with an evolvent-shaped vortex chamber. H & Fig. 1 shows a feed chopper, vdh at the side; Fig. 2 - the same, Vits at the top; Fig. 3 - a hopper with guide plates, a section; Fig. 4 shows a section A-A in Fig. 1; Fig. 5, a grinder, a common Vitz, as well as a section B-B in Fig. 2; Fig. 6 - a sweep of the grinding rotor with the image of hammers and cutting plates on it. chassis 1 and includes a frame 2 on which the lead 3 is mounted, a hopper 4 with guide plates 5 and 6, in the bottom 7 of which but the feeding window 8, the guide coil 9 and the fixed shear comb 1O of deck 11, the crushing chamber 12 with a hammer rotor 13, on both sides of which fans 14 are installed, the discharge pipe 15c with adjacent ventilation channels 16 and a jointly swirl connecting them , evolvent-shaped chambers 17, an additional deck 18 rotatably mounted, and an air guide 19. The rotor 13 is provided with cutting plates 2O, which are alternately mounted with the winding bars 2i, arranged along a helical line. The chopper works in the following way. With the help of shassi 1 he transports with a tractor to the place of work. Then the hydraulic system of the tractor set the frame of the shredder in the horizontal plane. The loading of the bunker 4, which is operated by the scribe 3 chrome-plated wheels, is carried out by a stacker or a grab loader. The mass in the bunker 4 by means of guide plates 5 and 6, located on its walls, in the direction of helix 9 paaaefc to the crushing chamber 1.2, with a hammer rotor 13. When the rotor 13 rotates, an emptying is created at the entrance of the crushing pus chamber. The air, together with the leafy mass or other material, is sucked inside the chamber 12, where it is ground by the action of the cutting 20 and the hammers 21 of the rotor. The feed grinding process is carried out by cutting, splitting and abrading. When you rechash. the pointed edge of the plate 2O is divided into fractions of predetermined sizes. When the hammers 21 of the rotor 13 interact with the immobilized anti-cutting elements 1O de and 11, the stalks of the form stem into pieces in places of concentrated loads determined by the size of the lateral gap between the hammers 21 and the conflicting elements of the 11O deck 11. When the working bodies of the rotor 13 are interacting, an additional loop 18, mounted with the possibility of rotation in the opposite direction of the rotor rotation, feed is abraded; due to the compressive, tensile and shearing forces transmitted by the face of the hammers 21 and the pointed edge of the cutting plates 20. The resulting crushed homogeneous mass is blown out by the rotor hammers from the crushing chamber 12 and directed to the discharge pipe 15 and the swirl chamber 17, where a potential for a discharge in the crushing chamber and an intense removing the feed to the pneumatic drive 19. Next, the product is transported by an additional stream created by the fans 14. This technical solution allows to reduce energy consumption, increase the efficiency of the process from grinding, as well as to expand the use of the grinder on both coarse and succulent feeds, as well as their mixtures, which will reduce the range of existing machines for feed processing. Claims of a feed chopper, including a feed hopper, at the bottom of which a feed window is filled, a fixed counter press, a crushing chamber with a hammer rotor, a discharge nozzle, characterized in that, in order to reduce the energy intensity, increase the efficiency of the grinding process, the rotor is equipped with burners plates installed alternately with hammers located along the helix, and in the crushing chamber under the shear comb an additional way is rotated vorezhuscha comb working elements which are made of trapezoidal shape, the unloading pipe with a swirl chamber formed in the shape of an involute.
