beneficial effects

The invention provides a soil crushing device for construction sites. It has the following beneficial effects:

(1) This kind of soil crushing device for construction sites first moves the sealing block upward, and the sealing block drives the clamping column to move upward inside the clamping hole. The sealing block is separated from the fixed block, and the soil blocks are poured into the upper end of the feed chute. , the soil block falls into the inside of the rotating block from the feeding trough and groove, and then the clamping column is inserted into the inside of the clamping hole, so that the sealing block blocks the feeding trough, and then the rotating motor is started, and the rotating motor drives the rotating shaft smoothly. When the rotating plate rotates clockwise, the rotating shaft drives the rotating plate to rotate clockwise. When the rotating plate rotates clockwise, the rotating plate drives the moving plate to rotate clockwise, and the moving plate drives the rolling roller to rotate clockwise. Then the rotating motor is started, and the rotating motor drives the rotating shaft counterclockwise. When rotating clockwise, the rotating shaft drives the rotating block to rotate counterclockwise, and the rotating block drives the extrusion device to rotate counterclockwise. The counterclockwise rotation of the rotating block drives the soil inside the rotating block to move irregularly. When the soil moves with the rotating plate, During the collision, the impact force of the rotating plate on the soil block will cause the soil block to shatter. The rotation plate and the rotating block rotating in opposite directions will make the movement of the soil block more violent. The high-speed moving soil block and the high-speed moving rotating plate will cause a collision. Violent collisions are generated to quickly crush large pieces of soil, avoiding the traditional crushing of using a mechanical sledgehammer to knock the soil blocks. After the knocking, the remaining soil blocks will be knocked with the continuous hammering of the sledgehammer. It becomes compressed and flat and difficult to be used again, resulting in waste of soil.

(2) This kind of soil block crushing device for construction sites. When the soil block collides with the conical block on the rotating plate, the sharp tip of the cone block hits the soil block, thereby increasing the size of the soil block by reducing the contact area. The pressure when the cone-shaped block collides with the cone-shaped block enables the cone-shaped block to carry out high-intensity crushing of some soil blocks that are difficult to crush, achieving the effect of enhancing the crushing efficiency.

(3) In this kind of soil crushing device for construction sites, the rotating shaft drives the rotating plate to rotate, and the rotating plate drives the rolling roller to rotate. The rolling roller presses the soil against the internal wall of the rotating block to more accurately crush some soil. The blocks are crushed more delicately. When the rolling roller comes into contact with some larger soil blocks, the soil blocks will squeeze the rolling roller, causing the rolling roller to drive the moving plate to move inside the moving groove, thus preventing the rolling roller from pushing the soil blocks to move. As a result, the rolling roller cannot roll through the soil clods, which reduces the crushing effect.

(4) In this kind of soil crushing device for construction sites, when the rolling rod squeezes the soil and the soil squeezes the baffle, the baffle rotates inside the rotating hole through the torsion spring, and the baffle squeezes the moving block to cause The moving block moves inside the movable groove. When the moving block moves, the squeezing spring is compressed. When the rolling rod passes through the baffle, the squeezing spring squeezes the moving block and the torsion spring drives the baffle to move, so that the soil on the upper side of the baffle is moved. The blocks are stirred up to make the soil blocks collide with the rotating plate, which enhances the practicality of the device.

(5) This kind of soil crushing device for construction sites first moves the sealing block upward, and the sealing block drives the clamping column to move upward inside the clamping hole. The sealing block is separated from the fixed block, and the soil blocks are poured into the upper end of the feed chute. , the soil blocks fall into the inside of the rotating block from the feed trough and groove, and then the clamping column is inserted into the inside of the hole, so that the sealing block blocks the feed trough to quickly seal the soil blocks, which enhances the device of practicality.

(6) This kind of soil block crushing device for construction sites, after the crushing is completed, separate the sealing block, rotate the fixed block, so that the feed chute opens downward, and the soil blocks slide out along with the feed chute, so that the unloading becomes quickly, enhancing the utility of the device.

(7) This soil crushing device for construction sites uses a rotating motor and a rotating motor to drive the device to move, thereby realizing automatic operation of the device, liberating manual labor intensity and enhancing the practicality of the device.

Working principle of the invention:

When in use, first move the sealing block 61 upward, and the sealing block 61 drives the clamping column 62 to move upward inside the clamping hole 24. The sealing block 61 is separated from the fixed block 21, and soil blocks are poured into the upper end of the feed chute 23. The soil blocks Fall into the inside of the rotating block 31 from the feeding chute 23 and the groove 33, and then snap the clamping column 62 into the inside of the clamping hole 24, so that the sealing block 61 blocks the feeding chute 23, and then start the rotating motor 8 to rotate The motor 8 drives the rotating shaft 51 to rotate clockwise, and the rotating shaft 51 drives the rotating plate 52 to rotate clockwise. When the rotating plate 52 rotates clockwise, the rotating plate 52 drives the moving plate 56 to rotate clockwise, and the moving plate 56 drives the rolling roller 59 to rotate clockwise. Turn clockwise, and then start the rotating motor 7. The rotating motor 7 drives the rotating shaft 32 to rotate counterclockwise. The rotating shaft 32 drives the rotating block 31 to rotate counterclockwise. The rotating block 31 drives the extrusion device to rotate counterclockwise. Through the counterclockwise rotation of the rotating block 31 To drive the soil clods inside the rotating block 31 to move irregularly. When the soil clods collide with the rotating plate 52, the impact force of the rotating plate 52 on the soil clods causes the soil clods to be crushed.
