[0034] See also Figure 1 The present embodiment provides a weighing and shredding device based on scrap steel recycling, including a shredding table 10, a shredding assembly 20, a first driving assembly 30, a second driving assembly 40 and a gathering assembly 50. The upper edge of the shredding table 10 is fixedly provided with a top plate 103 through a plurality of columns 102. The shredding assembly 20 is arranged above the shredding table 10. The first driving assembly 30 and the second driving assembly 40 are installed at the bottom of the top plate 103. The first driving assembly 30 is used to drive the shredding assembly 20 to reciprocate up and down. The second driving assembly 40 is used to drive the shredding assembly 20 to rotate. The gathering assembly 50 is arranged inside the shredding assembly 20. When the shredding assembly 20 moves upward, the gathering assembly 50 is used to gather the scrap steel on the upper part of the shredding table 10.

[0035] When scrap steel needs to be crushed, the scrap steel to be crushed can be placed on the upper part of the crushing table 10, and then the first driving component 30 is used to drive the crushing component 20 to move back and forth up and down, and the second driving component 40 is used to drive the crushing component 20 to rotate. When the crushing component 20 moves downward, it can act on the scrap steel on the upper part of the crushing table 10, and then exert pressure on the scrap steel to crush the scrap steel. Moreover, since the crushing component 20 is in a rotating state during the downward movement, the crushing component 20 can also cooperate with the crushing table 10 to exert horizontal shear force on the scrap steel when exerting pressure on the scrap steel, thereby improving the crushing effect of the scrap steel; when the crushing component 20 moves upward, the scrap steel on the upper part of the crushing table 10 is gathered by the gathering component 50, so that the scrap steel is gathered directly below the crushing component 20, so that the crushing component 20 can better crush the scrap steel again during the subsequent downward movement.

[0036] See also Figure 1 and Figure 2 In one embodiment, the first driving assembly 30 includes a second elastic member 301, a mounting plate 304, a first motor 305 and an eccentric wheel 306. The first motor 305 is fixedly arranged at the bottom of the top plate 103. The eccentric wheel 306 is installed at the output end of the first motor 305. The mounting plate 304 is arranged below the eccentric wheel 306 and is attached to the circumferential side wall of the eccentric wheel 306. An ear plate 303 is fixedly arranged on the side wall of the mounting plate 304. A guide rod 302 is fixedly arranged on the upper part of the crushing table 10. The guide rod 302 vertically penetrates the ear plate 303 and movably cooperates with the ear plate 303. One end of the second elastic member 301 is connected to the crushing table 10. The upper end is connected to the upper part, and the other end is connected to the ear plate 303, which is used to provide elastic support for the ear plate 303. The crushing assembly 20 includes a crushing box 201, a rotating rod 202 and a rotating drum 203. The bottom of the crushing box 201 is provided with a plurality of evenly distributed second crushing teeth 204, the rotating rod 202 is fixedly arranged on the upper part of the crushing box 201, and the rotating drum 203 is rotatably arranged at the bottom of the mounting plate 304. The upper end of the rotating rod 202 extends to the inside of the rotating drum 203 and is fixedly provided with a sliding column 205. The upper end of the sliding column 205 is connected to the inner top wall of the rotating drum 203 through a first elastic member 206. The first elastic member 206 is used to provide elastic support for the sliding column 205.

[0037] After the scrap steel is placed on the upper part of the shredding table 10, the eccentric wheel 306 is driven to rotate by the first motor 305. During the rotation of the eccentric wheel 306, the second elastic member 301 cooperates with the supporting effect of the ear plate 303 to drive the mounting plate 304 to move back and forth up and down. When the mounting plate 304 moves up and down, the shredding box 201 can be driven to move up and down by the rotating drum 203, the first elastic member 206, the sliding column 205 and the rotating rod 202. Through the repeated downward movement of the shredding box 201, the plurality of second shredding teeth 204 at the bottom thereof can repeatedly act on the scrap steel on the upper part of the shredding table 10, thereby crushing the scrap steel for multiple times.

[0038] See also Figure 1 and Figure 3 In one embodiment, the second driving assembly 40 includes a second motor 401, a driving gear 402 and a transmission gear 403. The second motor 401 is fixedly arranged at the bottom of the mounting plate 304. The driving gear 402 is fixedly installed at the output end of the second motor 401. The transmission gear 403 is fixedly arranged outside the rotating drum 203 and meshes with the driving gear 402. A vertically distributed key strip 207 is fixedly arranged on the inner wall of the rotating drum 203. A key groove (not shown in the figure) is provided on the side wall of the sliding column 205 for the key strip 207 to be embedded.

[0039] When the first motor 305 rotates to drive the crushing box 201 to move up and down, the second motor 401 drives the driving gear 402 to rotate, and the meshing action of the driving gear 402 and the transmission gear 403 drives the rotating drum 203 to rotate. When the rotating drum 203 rotates, the key bar 207 cooperates with the key slot to drive the sliding column 205, the rotating rod 202 and the crushing box 201 to rotate synchronously. When the crushing box 201 moves down and contacts the scrap steel, the crushing box 201 exerts downward pressure on the scrap steel to crush the scrap steel. At the same time, when the crushing box 201 rotates, several first The two crushing teeth 204 can generate horizontal shear force on the scrap steel, thereby tearing the scrap steel and realizing double crushing of the scrap steel; in the above process, when the crushing box 201 acts on the scrap steel, the mounting plate 304 drives the rotating drum 203 to continue to move downward, and at this time, the sliding column 205 moves upward along the inside of the rotating drum 203, and the first elastic member 206 is compressed. The first elastic member 206 transmits the downward pressure from the mounting plate 304 to the crushing box 201 in a slowly increasing manner through the sliding column 205 and the rotating rod 202, so that the second crushing teeth 204 can be smoothly inserted into the scrap steel to realize the crushing of the scrap steel.

[0040] See also Figure 3 and Figure 4In one embodiment, a conductive sheet 208 is embedded at the lower position of the inner wall of the rotating drum 203, a power supply (not shown in the figure) is arranged inside the crushing box 201, the sliding column 205 and the crushing box 201 are made of metal materials, and the folding component 50 includes an electromagnetic plate 501, which is fixedly arranged at the bottom center position of the inner side of the crushing box 201, and the electromagnetic plate 501 and the power supply, the electromagnetic plate 501 and the sliding column 205, and the conductive sheet 208 and the power supply are all connected by a wire 502.

[0041] When the mounting plate 304 drives the rotating drum 203 to move upward, the sliding column 205 slides down along the inside of the rotating drum 203 to the bottom. At this time, the sliding column 205 made of metal material contacts the conductive sheet 208, and the power supply realizes the electrical conduction of the electromagnetic plate 501 through the conductive sheet 208, the sliding column 205 and the corresponding wire 502. The electromagnetic plate 501 is energized to generate magnetism, and then a part of the crushed scrap steel chips are adsorbed at the bottom center position of the crushing box 201 through the crushing box 201. As the crushing box 201 moves upward, the crushing box 201 pulls up this part of the scrap steel chips, and the surrounding scrap steel chips are adsorbed around the pulled up scrap steel chips through magnetic conduction, and are pulled up synchronously with this part of the scrap steel chips. When the crushing box 201 moves up to a predetermined height position, the scrap steel chips gather themselves at the position below the crushing box 201 and pile up into a cone structure or a columnar structure, so that the scrap steel chips are automatically collected. When the crushing box 201 moves down again and acts on the scrap steel chips, the sliding column 205 The scrap steel chips move upward along the inside of the rotating drum 203 and are separated from the conductive sheet 208. The electromagnetic plate 501 is powered off and demagnetized, and the crushing box 201 applies pressure and shear force to the gathered scrap steel chips. The gathered scrap steel chips lose their magnetic attraction and can be better dispersed under the dual effects of pressure and shear force. After the crushing box 201 is repeatedly moved upward, the dispersed scrap steel chips can be repeatedly pulled up and gathered by the electromagnetic plate 501, and each time the electromagnetic plate 501 absorbs and pulls up the scrap steel chips, the scrap steel chips located at the center position will always be pulled to a position close to the crushing box 201. In the subsequent process of the scrap steel chips being compressed and sheared, the scrap steel chips originally located at the center position will be dispersed to the periphery. Therefore, the repeated upward movement of the crushing box 201 can not only realize the collection of the scrap steel chips, but also in the process of the scrap steel chips being collected, the scrap steel chips at the center position and the scrap steel chips at the edge position can be continuously exchanged, so that all the scrap steel chips can be effectively crushed.

[0042] See also Figure 1In one embodiment, a protective ring plate 101 is fixedly provided on the upper part of the pulverizing table 10, a material drop opening is opened on the pulverizing table 10 at the inner side of the protective ring plate 101, a support plate 105 is hingedly provided inside the material drop opening, a support leg 104 is fixedly provided on the bottom edge of the pulverizing table 10, one side of the support leg 104 is connected to the support plate 105 through a third driving assembly 60, and the third driving assembly 60 is used to drive the support plate 105 to rotate.

[0043] By placing the scrap steel to be crushed on the inner side of the retaining ring plate 101 and providing support for the scrap steel through the support plate 105, when the crushing box 201 moves downward, the crushing box 201 can enter the interior of the retaining ring plate 101, and then crush and shear the scrap steel on the inner side of the retaining ring plate 101. The setting of the retaining ring plate 101 can limit the position of the scrap steel to avoid the scrap steel being dispersed to the outer area of ​​the crushing box 201 during the crushing process; when the scrap steel is crushed, the third drive assembly 60 drives the support plate 105 to rotate downward to an inclined state. At this time, the crushed scrap steel located on the upper part of the support plate 105 can automatically slide away from the edge of the support plate 105, thereby realizing automatic discharge of the scrap steel.

In addition, since the crushing component 20 is in a rotating state during the downward movement, the crushing component 20 can also cooperate with the crushing table 10 when exerting pressure on the scrap steel. To apply a horizontal shear force to the scrap steel, thereby improving the crushing effect of the scrap steel; when the crushing component 20 moves upward, the scrap steel on the upper part of the crushing table 10 is gathered by the gathering component 50, so that the scrap steel is gathered directly below the crushing component 20, so that the crushing component 20 can better crush the scrap steel again during the subsequent downward movement.
