[0024] like Figure 1-5As shown, a concrete crushing device for steel recycling includes an electric pick body 1; a transparent plate 11 is fixedly connected to the middle of the electric pick body 1, and the transparent plate 11 is arranged in a trumpet shape; a motor 12 is installed on the top of the electric pick body 1; a first bevel gear 13 is fixedly connected to the output end of the motor 12; a second bevel gear 14 is rotatably connected to the middle of the electric pick body 1; the second bevel gear 14 and the first bevel gear 13 are arranged to mesh with each other; a connecting piece 15 is fixedly connected to the middle of the second bevel gear 14; the connecting piece 15 The middle part is fixed with bristles 16, and the middle part of the bristles 16 is in contact with the inner wall of the transparent plate 11; when working, the staff needs to connect the electric pick body 1 to the power supply, and after the output end of the electric pick body 1 is in contact with the concrete to be crushed, turn on the switch of the electric pick body 1 and crush the concrete. By setting a transparent plate 11 in the middle of the electric pick body 1, the transparent plate 11 will block the flying gravel and part of the dust when the electric pick body 1 is working. At the same time, the output end of the electric pick body 1 needs to be in contact with the concrete to be crushed. When the position is changed, the staff can adjust the output end position of the electric pick main body 1 through the transparent plate 11. When a lot of dust is accumulated in the middle of the transparent plate 11, the staff can turn on the motor 12 switch, so that when the motor 12 is working, its output end will drive the first bevel gear 13 to rotate, and the second bevel gear 14 meshing with the first bevel gear 13 will also rotate, so that when the connecting member 15 is in motion, the bristles 16 in the middle will scrape and clean part of the dust attached to the inner wall of the transparent plate 11. This step is combined with the transparent plate 11, so that when the staff uses the electric pick main body 1 to crush concrete, the transparent plate 11 will block the gravel and protect the staff's face or body parts, reducing the problem of some of the broken gravel causing damage to the human body. At the same time, the bristles 16 in contact with the inner wall of the transparent plate 11 can improve the cleanliness of the inner wall of the transparent plate 11, reducing the problem that it is difficult for the staff to observe the working condition of the output end of the electric pick main body 1 through the transparent plate 11.

[0025] like Figure 1-5As shown, two groups of fixed blocks 2 are fixedly connected to the ends of the connecting member 15; a connecting plate 21 is fixedly connected to the ends of the fixed blocks 2; a sliding rod 22 is fixedly connected to the middle of the fixed block 2; a sliding block 23 is slidably connected to the middle of the sliding rod 22; two groups of baffle rods 24 are fixedly connected to the middle of the sliding block 23, and the two groups of baffle rods 24 are staggered; the ends of the baffle rods 24 are in contact with the middle of the bristles 16; when working, a slidable sliding block 23 is provided at the end of the connecting member 15, so that when the connecting member 15 moves to the bottom end of the electric pick body 1 under the action of the second bevel gear 14, the sliding block 23 can slide in the middle of the sliding rod 22 under the action of the overall gravity of the sliding block 23, and The two sets of baffles 24 arranged in the middle of the slider 23 will contact the bristles 16 of soft material, and at the same time remove the impurities attached and agglomerated in the middle of the bristles 16. At the same time, when the connecting piece 15 moves to the highest end, it can use gravity to slide downward again, and repeat this process. This step, combined with the two sets of baffles 24, can reduce the problem of more impurities adhering to and agglomerating in the middle of the bristles 16, making it difficult for the bristles 16 to clean the inner wall of the transparent plate 11 after long-term use, and reduce the problem of frequent manual cleaning by staff. In conjunction with the fixed block 2, the movement trajectory of the slider 23 can be guided to reduce the phenomenon of angle deviation when the slider 23 slides down.

[0026] like Figure 1-5 As shown, two groups of support plates 3 are fixedly connected to the middle of the connecting plate 21; two groups of springs 31 are fixedly connected to the middle of the support plate 3; a gasket 32 ​​is fixedly connected to the top of the spring 31; the gasket 32 ​​is cylindrical; when working, by arranging two groups of support plates 3 in the middle of the connecting plate 21, the slider 23 will contact the two groups of gaskets 32 in turn when sliding down, and after contacting the middle of the gasket 32, it will squeeze the middle of the two groups of springs 31 to deform, and make the spring 31 have elastic force, this step cooperates with the spring 31 with elastic force, so that the slider 23 can slide up and down multiple times in the middle of the slide rod 22 after contacting the gasket 32, thereby reducing the problem of jamming of the slider 23 position and reducing the dust agglomeration in the middle of the slider 23.

[0027] like Figure 1-5As shown, the middle part of the connecting member 15 is rotatably connected with a cleaning barrel 4; the interior of the cleaning barrel 4 is hollow; the middle part of the cleaning barrel 4 is in contact with the outer wall of the transparent plate 11; a plurality of groups of pull ropes 41 are fixedly connected to the inner wall of the cleaning barrel 4 in a circular array; a counterweight 42 is fixedly connected to the end of the pull rope 41; during operation, a rotatable cleaning barrel 4 is provided in the middle part of the connecting member 15, so that when the connecting member 15 moves, the pull rope 41 can be rotated in the middle part of the connecting member 15 by means of the friction between the middle part of the cleaning barrel 4 and the surface of the transparent plate 11, and at the same time, the plurality of groups of pull ropes 41 and the counterweight 42 approach the inner wall of the cleaning barrel 4 until the two collide with each other. This step cooperates with the cleaning barrel 4 to further improve the cleanliness of the surface of the transparent plate 11, reduce the problem of a small amount of dust adhering to the outer wall of the transparent plate 11 and blocking the sight of the staff, and cooperates with the force generated after the collision of the counterweight 42 to reduce the attachment time of impurities in the middle part of the cleaning barrel 4.

[0028] like Figure 1-5 As shown, the end of the connecting plate 21 is fixedly connected to a top plate 5; the middle part of the top plate 5 is arc-shaped; during operation, by arranging the top plate 5 in the middle part of the connecting plate 21, the external dust will contact the arc-shaped top plate 5 before approaching the middle part of the connecting plate 21. This step cooperates with the top plate 5 to reduce the adhesion of some dust to the middle part of the connecting plate 21, resulting in more impurities or gravel in the middle part of the slider 23 and the sliding groove, resulting in the problem of difficulty in the movement of the slider 23.

[0029] like Figure 1-5 As shown, a friction ball 6 is fixedly connected to the end of the baffle rod 24; the friction ball 6 is arranged to be in contact with the middle of the bristles 16; when working, by arranging the friction ball 6 at the end of the baffle rod 24, two groups of friction balls 6 will contact the surface of the bristles 16. This step cooperates with the friction ball 6 to increase the contact area between the bristles 16 and the bristles 16, and further improves the accuracy of cleaning the middle of the bristles 16.

[0030] like Figure 1-5 As shown, a rubber pad 7 is fixedly connected to the middle part of the counterweight block 42; during operation, by arranging the rubber pad 7 in the middle part of the counterweight block 42, when the counterweight block 42 hits the inner wall of the cleaning tube 4, the rubber pad 7 will contact the inner wall of the cleaning tube 4 before. This step cooperates with the rubber pad 7 to reduce the wear on the inner wall of the cleaning tube 4 during the impact process, thereby increasing the service life of the two.

[0031] The working principle is that after the electric pick body 1 is connected to the power supply and the output end of the electric pick body 1 is brought into contact with the concrete to be crushed, the electric pick body 1 is turned on and the concrete is crushed. A transparent plate 11 is provided in the middle of the electric pick body 1 so that when the electric pick body 1 is working, the transparent plate 11 will block the flying gravel and some dust. At the same time, when the position of the output end of the electric pick body 1 needs to be changed, the staff can adjust the position of the output end of the electric pick body 1 through the transparent plate 11. When a lot of dust is accumulated in the middle of the transparent plate 11, the staff can turn on the motor 12 to make the concrete crushed. When the motor 12 is working, its output end will drive the first bevel gear 13 to rotate, and at the same time, the second bevel gear 14 meshing with the first bevel gear 13 will also rotate, so that when the connecting member 15 is moving, the bristles 16 in the middle will scrape and clean part of the dust attached to the inner wall of the transparent plate 11. By providing a slidable slider 23 at the end of the connecting member 15, when the connecting member 15 moves to the bottom end of the electric pick body 1 under the action of the second bevel gear 14, the slider 23 can slide in the middle of the slide rod 22 under the action of the overall gravity of the slider 23, and the two sets of blocking rods 24 provided in the middle of the slider 23 will The connecting member 15 is in contact with the bristles 16 of the soft material, and the impurities attached to and agglomerated in the middle of the bristles 16 are removed. At the same time, when the connecting member 15 moves to the highest end, it can slide downward again by gravity, and this is repeated. By arranging two groups of support plates 3 in the middle of the connecting plate 21, the slider 23 will contact the two groups of gaskets 32 in turn when sliding down, and after contacting the middle of the gasket 32, it will squeeze the middle of the two groups of springs 31 to deform, and make the springs 31 have elastic force. By arranging a rotatable cleaning cylinder 4 in the middle of the connecting member 15, the connecting member 15 can be moved by the middle of the cleaning cylinder 4 and the transparent plate 11. The friction between the surfaces can make the pull rope 41 rotate in the middle of the connecting piece 15, and at the same time, multiple groups of pull ropes 41 and counterweight blocks 42 approach the inner wall of the cleaning tube 4 until the two collide with each other. By providing a top plate 5 in the middle of the connecting plate 21, the external dust will contact the arc-shaped top plate 5 before approaching the middle of the connecting plate 21. By providing a friction ball 6 at the end of the baffle rod 24, the two groups of friction balls 6 will contact the surface of the bristles 16. By providing a rubber pad 7 in the middle of the counterweight block 42, when the counterweight block 42 hits the inner wall of the cleaning tube 4, the rubber pad 7 will contact the inner wall of the cleaning tube 4 before.
