Description

(54) DEVICE FOR CRUSHING THE DIMENSION

one

The invention relates to construction and mining machines, and more specifically to devices for the crushing of oversize.

A device for crushing oversize is known, which includes a base machine, a frame, a working bar with a percussion instrument and a cable-blocking system of a drive 1.

The disadvantage of the device is a small unit impact force, which limits the performance.

A device for crushing non-dimensions is known, comprising a base machine, an arrow with a carrying frame, a frame with lifting hydraulic cylinders with rods pivotally suspended from it with rods and rigidly attached to them-clamps, a hammer member in the form of a pneumatic cylinder with a rod fixed on the frame and a housing, on the front side which is mounted working tool 2.

A disadvantage of the device is that a expansion cylinder is used to release the pneumatic cylinder, which reduces productivity, since additional time is required to control the expansion cylinder.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that in a device for crushing oversize, including a supporting frame with upper and lower beams with hydraulic cylinders pivotally suspended from it, the rods of which have grippers, a percussion mechanism in the form of a pneumatic cylinder with a working tool, the rod of which is connected to the frame, is equipped with a pneumatic cylinder

10 from the side of the arms by inclined guides, and in the lower part - by a ring installed with the possibility of interaction with the arms, with the frame in the lower beam having a central window with grooves,

15 made with the possibility of moving the pneumatic cylinder and inclined guides into them, respectively, and the side windows in which are placed the rods of the hydraulic cylinders with the possibility of their displacement in the horizontal plane, while the hydro20 cylinders have roller bearings installed with the possibility of interaction with inclined guides, and the grippers are spring-loaded. FIG. 1 shows a device, side view; in fig. 2 is a section A-A in FIG. 1. The device consists of a frame 1c lifting hydraulic cylinders 2 with rods pivotally suspended thereto 3. At the free ends of the rods 3 hydraulic cylinders 2, the clamps 4 are fixed, connected by springs 5. The top of the frame 1 is rigidly fixed to the rod 6 of the pneumatic cylinder 7, made with a grip ring 8 and inclined guides 9 provided with a percussion tool 10. In the lower part, the lifting cylinders 2 are equipped with roller bearings AND for inclined guides 9. The lower beam 12 of the frame 1 has a central window 13 with grooves 14 for prevent rotation of the pneumatic cylinder 7 and side openings 15 for the passage of the rods 3 lifting hydraulic cylinders 2. When the device is operated by means of lifting hydraulic cylinders 2 suspended from the frame 1, driven by the working fluid, rods 3 and grippers 4, the pneumatic cylinder 7 with a ring 8, inclined guides 9 and the working tool 10 rises up and air is compressed inside the cylinder 7. During the movement of the pneumatic cylinder 7, the inclined guides 9 interact with the rolling mechanism 11 and when the maximum lift height is reached 7 nevmotsilindra diluted with lifting cylinders 2 schtokami 3, grippers 4 are emitted from engagement with the gripping ring 7 of the air cylinder 8 and the latter falls down without obstacle. To return the pneumatic cylinder 7 to the initial position, the pawl 3 with the grips 4 attached to it go down, the claws 4 slide along the inclined guides 9, move apart and pass the ring for the gripper 8 are compressed by means of the clamping mechanism 5, grab the ring for the gripper 8 of the pneumatic cylinder 7 and the process is repeated. The inclined guides 9 ensure reliable engagement and disengagement of the grippers 4 by the ring for gripping 8 of the pneumatic cylinder 7, and moving in the grooves 14 of the central hole 13 of the lower part 12 of the frame 1, exclude the possibility of rotation of the pneumatic cylinder 7. The hinged connection of the frame 1 to the base frame with The booms 16 and hydraulic cylinders 17 and 18 provide the ability to adjust the height and direction of the impact. The application of the invention increases production by automating the control of the percussion mechanism. The invention of the device for crushing oversize, including a supporting frame with upper and lower beams with hydraulic cylinders pivotally suspended to it, the rods of which have grips, a percussion mechanism in the form of a pneumatic cylinder with a working tool, the stem of which is connected to the frame, characterized in that performance, the pneumatic cylinder is provided on the gripper side with inclined guides, and in the lower part - with a ring installed with the ability to interact with the grippers, and the frame in the lower beam has a central a window with grooves made to move in them a pneumatic cylinder and inclined guides, respectively, and side windows in which hydraulic cylinder rods are placed with the possibility of their movement in a horizontal plane, the cylinders have roller bearings mounted with the possibility of interaction with inclined guides, and the grippers are spring loaded.
