[0013] The following is a description of the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.

[0014] Example 1 A steel recycling and crushing device includes: a main housing 1, a crushing roller 2, a secondary housing 3, a first dust collection assembly 4, and a second dust collection assembly 5. The main housing 1 has a feed inlet 11 at its top. Inside the main housing 1 are multiple sets of staggered inclined conveyor plates 12. The uppermost inclined conveyor plate 12 is connected to the feed inlet 11 at its high end, and the bottom end of the lowermost inclined conveyor plate 12 is located above the crushing roller 2. Inside the main housing 1 is an inclined filter screen 13 located below the crushing roller 2. The main housing 1 has a collection box 6 located at the bottom of the inclined filter 13. The auxiliary housing 3 is connected to the side of the main housing 1 and the feed inlet 31 is connected to the bottom of the inclined filter 13. The dust suction hood 41 of the first dust suction assembly 4 is located below the uppermost inclined conveyor plate 12. The dust suction hood 51 of the second dust suction assembly 5 is located inside the auxiliary housing 3. The auxiliary housing 3 has a discharge port 32 at the bottom and a movable baffle 33 at the upper end of the discharge port 32.

[0015] like Figures 1-2 As shown, the working principle of this utility model is as follows: Scrap steel is fed in through the inlet at the top of the main box and falls onto the uppermost inclined conveyor plate. Multiple sets of staggered inclined conveyor plates form a tortuous conveying path, and the scrap steel slides down the inclined plates step by step under the action of gravity, realizing buffered conveying from the inlet to the crushing roller. After being conveyed, the scrap steel enters the crushing rollers for crushing. The crushed steel falls into the inclined filter screen below. Qualified steel pieces smaller than the filter screen aperture slide down the inclined surface into the collection box; larger steel pieces that are not completely crushed cannot pass through the filter screen and slide down the inclined surface towards the feed inlet of the auxiliary box to enter the secondary processing process. The first dust collection hood of the first dust collection component is located below the uppermost inclined conveyor plate and can capture the dust generated during the fall of scrap steel; the second dust collection hood of the second dust collection component is located inside the upper part of the auxiliary box and collects the dust generated during secondary processing, thus achieving dust control throughout the entire process. Uncrushed steel in the secondary chamber can be crushed again (after being removed and reprocessed). After processing, it is discharged through the bottom discharge port. The movable baffle at the discharge port is used to control the timing of unloading. At the same time, the discharge port can be closed to ensure that the secondary processing dust of the steel in the secondary chamber is not spilled out. It can be opened after processing.

[0016] As a further preferred embodiment, the main housing 1 has a support 14 at its bottom, and a limiting rod 141 is threadedly connected to the support 14. The collection box 6 is inserted into the main housing 1 from bottom to top and fixed in position by the limiting rod 141. The support at the bottom of the main housing supports the overall structure, and the limiting rod on the support is threaded to achieve telescopic connection. The collection box adopts a drawer-type design, is inserted from the bottom of the main housing from bottom to top, and its position is fixed by rotating the limiting rod so that its end abuts against the outer wall of the collection box; when disassembling, the collection box can be pulled out by rotating the limiting rod in the opposite direction, realizing quick assembly and disassembly of the collection box.

[0017] As a further preferred embodiment, the sub-box 3 is provided with a guide plate 34 inside. The lower end of the guide plate 34 is located on the right side of the discharge port 32 and the upper end of the baffle 33. The upper end of the guide plate 34 is fixed to the right side of the interior of the sub-box 3. A cylinder 35 is provided at the bottom of the sub-box 3. A guide rod 331 is provided on the right side of the baffle 33. The piston rod 351 of the cylinder 35 is provided with a connecting rod 352. The connecting rod 352 passes through the sliding groove of the sub-box 3 and connects to the guide rod 331. The guide plate inside the sub-box is inclined, with its upper end fixed to the right side wall and its lower end extending to the right side of the discharge port and the upper end of the baffle, which can guide the steel material to concentrate at the discharge port. The guide rod on the right side of the baffle is connected to the piston rod of the cylinder through a connecting rod. When the cylinder drives the piston rod to extend and retract, the connecting rod slides along the sliding groove of the sub-box, driving the baffle to move left and right, thereby realizing the opening and closing of the discharge port.

[0018] As a further preferred embodiment, the first dust collection assembly 4 further includes a first dust collection pipe 42 and a first vacuum cleaner 43. The first dust collection pipe 42 connects the first dust collection hood 41 and the first vacuum cleaner 43, and the first vacuum cleaner 43 is disposed on the top of the main housing 1. The second dust collection assembly 5 further includes a second dust collection pipe 52 and a second vacuum cleaner 53. The second dust collection pipe 52 connects the second dust collection hood 51 and the second vacuum cleaner 53, and the second vacuum cleaner 53 is disposed on the top of the auxiliary housing 3. The first dust collection assembly consists of a first dust collection hood, a first dust collection pipe, and a first vacuum cleaner. The first dust collection hood faces the dust-generating area and guides the dust to the first vacuum cleaner fixed on the top of the main housing through the first dust collection pipe. The second dust collection assembly adopts the same structural logic. The second vacuum cleaner is fixed on the top of the auxiliary housing and is connected to the second dust collection hood through the second dust collection pipe.

[0019] As a further preferred embodiment, the feed inlet 11 at the top of the main box 1 is flared. The wide opening facilitates the batch feeding of scrap steel and avoids spillage during feeding.
