[0027] Furthermore, in this embodiment, telescopic rods 108 are connected between both sides of the cover plate 101 and the crushing box 100. Both ends of the telescopic rods 108 are screwed to the cover plate 101 and the crushing box 100 respectively. A motor is arranged inside the motor box 102. The cover plate 101 is convenient to open and close through the telescopic rods 108.

[0028] In this embodiment, the crushing assembly 300 includes a rotating rod 301, a connecting rod 303 and a crushing block 304. One end of the rotating rod 301 is in transmission connection with the output end of the motor. The connecting rod 303 is arranged on the outer surface of the rotating rod 301. The crushing block 304 is screwed to the end of the connecting rod 303. The rotation of the rotating rod 301 is controlled by the motor in the motor box 102. The crushing block 304 is installed on the rotating rod 301 through the connecting rod 303.

[0029] In this embodiment, a plurality of mounting holes 302 are equidistantly opened on the outer surface of the rotating rod 301. The connecting rod 303 is in threaded fit with the mounting holes 302 and is fixed with a preset nut. A fixing plate 201 is welded on the outside of the crushing box 100. The other end of the rotating rod 301 penetrates through the crushing box 100 and the fixing plate 201 and is rotatably connected to the fixing plate 201 and the crushing box 100. The installation position and quantity of the crushing block 304 can be selected according to the crushing requirements through the design of the mounting holes 302. The rotation of the other end of the rotating rod 301 is limited by the fixing plate 201 to be stable.

[0030] In this embodiment, a cross bar 107 is welded to the inner side of the crushing box 100. The rear end of the push rod 105 is screwed to the cross bar 107. A connecting plate 106 is arranged between the front end of the push rod 105 and the baffle 104. The connecting plate 106 is fixedly connected to the baffle 104 and screwed to the push rod 105. The push rod 105 is fixed by the cross bar 107, and the push rod 105 is connected to the baffle 104 through the connecting plate 106, so as to realize the opening and closing control of the baffle 104 by the push rod 105.

[0031] In this embodiment, the upper end of the threaded column is inserted into the bottom of the crushing box 100. A pin shaft penetrates between the upper end of the threaded column and the crushing box 100. The threaded column is fixedly connected to the fixing plate 201. A connecting hole 205 that is in threaded fit with the threaded column is formed on the surface of the bottom plate 203. The connection between the threaded column and the crushing box 100 is fixed by the pin shaft, and the disassembly and assembly of the threaded column and the crushing box 100 are facilitated.

[0032] In this embodiment, springs are located on both sides of the threaded column. Reinforcing ribs 208 are wound on the outer surface of the springs. The ends of the reinforcing ribs 208 and the springs are fixedly connected to the damping plates 207. The damping plates 207 are respectively screwed to the bottom plate 203 and the fixing plate 201. The springs are reinforced by the reinforcing ribs 208. The mechanical strength of the springs is increased by the reinforcing ribs 208, so that they are more solid when bearing large loads or vibrations, reducing deformation and damage, and dispersing stress, thereby prolonging the service life of the springs. The bottom plate 203 is connected to the fixing plate 201 through the damping plates 207, and an overhead structure is formed by the springs, which is convenient for elastic vibration damping, reducing the rapid failure of the elastic performance of the springs in the long-term vibration damping state. The bottom plate 203 is connected to the fixing plate 201 through the damping plates 207, and an overhead structure is formed by the springs, which is convenient for elastic vibration damping.

[0033] In this embodiment, the ground plug post 204 is designed in a conical shape, and the effect of inserting the support structure into the ground is realized through the ground plug post 204.

[0034] Specifically, when crushing the raw material of the steel slag subgrade soil, first install the position of the crushing box 100 by using the support assembly 200. The support assembly 200 inserts the ground plug post 204 and the threaded rod 202 into the ground, inserts the bottom end of the crushing box 100 on the upper end of the threaded rod 202, and sets a pin shaft for fixation. The support is carried out through the threaded rod 202 and the ground plug post 204. The surface of the bottom plate 203 is horizontal with the ground, and the crushing box 100 is installed. When the crushing box 100 is performing crushing work, vibrations will occur. The springs are reinforced by the reinforcing ribs 208. When the fixing plate 201 is subjected to a force, the fixing plate 201 is vibration-damped through the springs, ensuring the stability of the crushing box 100;

[0035] When the crushing box 100 performs the crushing work, manually open the cover plate 101. The telescopic rod 108 between the cover plate 101 and the crushing box 100 stretches, and the raw materials are imported. Then cover the cover plate 101 and fix the cover plate 101 with bolts. Control the motor in the motor box 102 to start and control the rotation of the rotating rod 301 through the configured switch. Select the installation position and quantity of the crushing blocks 304 according to the crushing requirements. Install the crushing blocks 304 in the installation holes 302 of the rotating rod 301 by using the connecting rod 303. The rotating rod 301 drives the crushing blocks 304 to rotate to perform the crushing work on the raw materials in the crushing box 100. After the crushing is completed, control the push rod 105 on the cross bar 107 to retract through the switch. Based on the connecting plate 106 connected by screws, drive the baffle 104 to move together. After the baffle 104 is opened, the crushed raw materials flow out from the discharge port 103.

[0036] In addition, it should be noted that the selection of the size of the support assembly 200 and the damping force of the spring requires sufficient strength and stability to prevent bending or breaking during the crushing process and ensure that the ground can withstand the insertion force of the support assembly 200 and the additional load during the operation of the crushing box 100.

[0037] The components such as the crushing box 100, the cover plate 101, the motor box 102, the discharge port 103, the baffle 104, the push rod 105, the connecting plate 106, the cross bar 107, the telescopic rod 108, the fixing plate 201, the fixing plate 201, the threaded rod 202, the bottom plate 203, the ground plug post 204, the damping spring 206, the damping plate 207, the reinforcing rib 208, the rotating rod 301, the connecting rod 303, and the crushing block 304 of the present utility model are all common standard parts or parts known to those skilled in the art.
