Description

(54) WORKING BODY OF THE FEED LOADER

These 12 are fixed on supports 13, the length of which is greater than the height of the processed feed mass. In the lower part of the frame 14, fastened with a crane-beam, a transporting spike 15 is installed and a stitch 16, for example, made of synthetic material, is installed. Perpendicular to the crane-beam next to the installation, the conveyor 17 of the finished product is mounted. To automate the IB process, the extreme positions of the trolley travels on the crane-girder are set to two quick-detachable contactless sensors 18, at distances equal to the length of the working body of the feed loader; Similar sensors 19 are mounted on the crane rail 12, and adjustable intake depth sensors 20 are also mounted on the forklift frame 4.

Working body . loader of feed / attached to the frame, nmeuyu1, it can rotate using, for example, two hydraulic cylinders 22 and adjustable angles about axis 2. The working body consists of an open working bottom: measures, including a casing 25 with a guide vane and two vortex chambers (sinuses) 24, adjustable spring-loaded decks 25 with windows 55 for passage: material, two horizontal parallel hollow rotating towards each other rotor 27. The drive of the shredder is received from two electric motors 28 by means of a wedge nnyh -Sending. The guide plate contains three figured plates 29 located in the exit zone of the crushed product and installed under different for fuller use of the air flow. In order to displace the center of the torsional-twist lol and increase the radial components of the air flow velocity, which ultimately determine the air flow of the working body, two vortex chambers 24 are made on the casing near the rotors. The rotor includes two disks 30 with cantilever shafts. and 31, interconnected by block blades and hammers 32. TaiKoe breaking allows to reduce the metal content of the rotor and free up space in the crusher to create a potential-vortex field and free flow. In order to eliminate obstacles, a disk 33 with a two-speed hammer MI is mounted on the working body at the end of each shaft 31. The blade unit consists of two blades 3.4 each next to the rotor circumference, interconnected by segments to create the necessary strength.

The device works as follows.

After adjusting the quick-detachable sensors 18, 19, 20 to the volume of the processed feed mass 5, the electric motor of the 1J crane beam 9 is activated,

four

when moving, the sensor / riodraiovoy guide 12, which is configured as the first run, closes, includes a relay for starting the electric motor of the drive 8 of the carriage 6, which is in one of the extreme positions 18, the working body of the feed loader 1 by the hydraulic cylinders 22, respectively, turning in the direction of the working movement and lowered to the first tuned sensor 20 on the forklift 4. When the parallel rotors 27 (Fig. 2) rotate, a vacuum is created against each other at the entrance to the grinder. The leafing mass or other material is captured by the hammers 32 and the blades 34, put into the working chamber opened from the bottom and directed inside the hollow rotors under the action of centripetal forces. The flicker of the vortex chambers 24 organizes the air flow through the circuit of the diametric fan, i.e., it facilitates the through-flow through the cross section of the grinding chamber. It magnifies the radial components of the total air flow. Hammers mounted on two discs 33 cut off the mass to be captured from the main monolith. The material to be ground, with a part of the air flow, falling under the blows of hammers 32, is thrown onto decks 25 with oxides 26, which contribute to a better passage of the material to be captured through the working body strip. Under,: .1m hammers and bumps on adjustable decks, the material is ground. The image of the kinom air-annular layer will mix the material to the guiding structure. Under the action of centrifugal forces, the air is pushed out of the rotors, again receiving energy from the blades and hammers. The plates 29 of the driver unit prevent it from twisting and increase the radial component of the flow, which carries the crushed product through the outlet of the casing 23 to the guide wall 16 (Fig. 1), from where it enters the screw 15, sending the finished product to perpendicularly located conveyor 17 for feeding mass to the feed shop, for storage, for transporting carts, etc. When sensors 18 are closed on crane 9, the following occurs: relay for reversing the electric motor of the hydraulic drive -S of the truck 6 relays for switching the electroma nit respective distributor spool for rotation to -srabatyvanie gidrotsilindr01N adjustable stops on shtogkah; the switch-on relay of the distributor for lowering the working body / hydrocyl syndrome 5 of the forklift 4 to the regulated depth. After reaching the last lower sensor 20 on the frame of the forklift 4, making a working stroke and closing the section two two -HiKOB / 5, a command is given to lift the working device Y to the first upper sensor 20 and the electric motor 1 of the drive 8 of the cart 6. After closing the upper sensor 20 the actuator // crane I is activated, which moves and then is braked by the sensors 19 installed on the crane guide 12. When the sensor 19 is triggered, the trolley drive is activated and the process is repeated. When the last beam 19 is closed by the crane beam 9 and the working pick is completed with the chopper, the beam returns to its initial position with the working tool raised. The performance of the feed loader is regulated by the hydraulic drive of the WTO of the electric drive 8 of the trolley 6, the hydraulic cylinders turning the working member, the distance of installation of the sensors 20 on the frame of the forklift 4. Provides control from overloads of the drive motor of the working member by reducing the feed of the drive gear 8 of the trolley 6 and by lifting the chopper hydraulic cylinder 5 lifts 4.

The invention is not limited to the example of its implementation described above, on the basis of it — it can be provided with other uses and other embodiments beyond the scope of the claims.

The use of the proposed working body of the Kormov loader provides, in comparison with the existing devices, a significant increase in productivity - as a result of reducing idle motions of the working body and loader in

whole; energy intensity of the process; reliability and durability of the working body (its maintenance is reduced to a minimum); full automation of work management.
