Description

Technical Field

[0001] This utility model relates to the technical field of metal waste treatment equipment, specifically to a waste iron drum crushing device. Background Technology

[0002] With the widespread use of scrap iron drums in industries such as petrochemicals, coatings, and lubricants, the number of scrap iron drums is increasing year by year. As recyclable metal, scrap iron drums usually need to be crushed before briquetting or smelting to reduce transportation volume and improve metal recycling efficiency. Currently, most common scrap iron drum crushing equipment adopts a dual-shaft crushing roller structure, which uses interlocking crushing blades to shear, squeeze, and tear the drum body.

[0003] However, the cylindrical structure of the scrap iron drum makes it prone to rolling. After falling into the crushing chamber, it is easy for the drum to roll and deviate. In particular, when the drum enters the area above the crushing roller, it tends to roll along the gap between the crushing roller and the side wall of the shell, and rolls back and forth in the side area. It is difficult for the drum to move to the engagement position of the crushing roller in time, which results in the drum not being engaged in time. This not only causes the crushing roller to run idle, but may also cause jamming, jumping, and tumbling, thereby reducing the crushing efficiency and affecting the stable and continuous operation of the equipment. Therefore, it needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a waste iron drum crushing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A scrap iron drum crushing device includes a support frame and a housing mounted on the support frame. Rotatable crushing rollers are arranged opposite each other inside the housing frame. A discharge hopper is provided at the lower end of the housing frame. Pushing plates parallel to the axis of the crushing rollers are respectively provided on opposite sides of the housing frame. The pushing plates are used to push the scrap iron drums toward the meshing area of ​​the crushing rollers. Displacement grooves extending along the sliding direction of the pushing plates are respectively provided on opposite side walls of the housing frame. Push-pull rods extending from the displacement grooves are provided on the sides of the pushing plates. A push-pull mechanism connected to the corresponding push-pull rods is provided on the housing frame. Fixed rods are arranged opposite each other on the support frame. A striking mechanism for striking the discharge hopper is provided between the fixed rods.

[0006] Furthermore, the push-pull mechanism includes a sliding plate disposed on the outer wall of the housing, a sliding groove disposed inside the sliding plate, a movable groove disposed on the sliding plate communicating with the sliding groove, a slider disposed inside the sliding groove, and a vertical plate extending from the movable groove disposed on the slider.

[0007] Furthermore, a cover is provided on the side of the shell, and a rotating rod extending from both sides of the cover is provided inside the cover. A rotating disk is provided at one end of the rotating rod near the vertical plate, and an eccentric column is provided on the rotating disk. A connecting column is provided on the vertical plate, and a connecting rod is provided between the eccentric column and the connecting column.

[0008] Furthermore, a dual-axis motor for driving the rotating rod is provided between the oppositely positioned covers.

[0009] Furthermore, a drive motor is provided outside the housing, and one of the crushing rollers has its shaft end extending outside the housing and connected to the output end of the drive motor.

[0010] Furthermore, the striking mechanism includes a rotating shaft disposed between the fixed rods, one end of which extends out from the side of the fixed rod, and a driven sprocket is provided at the extended end. A driving sprocket is provided on the shaft end that connects the crushing roller to the drive motor, and a chain is provided between the driving sprocket and the driven sprocket.

[0011] Furthermore, the rotating shaft is equipped with striking bars for striking the hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by providing reciprocating pusher plates on opposite side walls within the housing, and in conjunction with displacement grooves and a push-pull mechanism on the side walls of the housing, allows the pusher plates to periodically push the scrap iron drum towards the meshing area of ​​the crushing roller. This effectively prevents the scrap iron drum from rolling, shifting, or stagnating on the side of the crushing roller due to its cylindrical structure. This structure enables the scrap iron drum to quickly enter the meshing position of the crushing roller, improving crushing efficiency, reducing idling and jamming, and enhancing overall crushing stability and processing capacity.

[0013] This invention uses a striking mechanism to drive a striking bar to periodically strike the discharge hopper, preventing material from accumulating or adhering inside the hopper, thus preventing residual material and blockage. This allows the crushed scrap iron drum fragments to be discharged smoothly, improving discharge efficiency and the continuous working performance of the equipment. Attached Figure Description

Detailed Implementation

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0020] The following is in conjunction with the appendix Figures 1-4 This embodiment will be described in further detail.

[0021] Please see Figures 1-4 The waste iron drum crushing device in this embodiment includes a support 100 and a housing 101 disposed on the support 100. The housing 101 is fixedly disposed on the support 100. Two rotatable crushing rollers 102 are disposed opposite each other inside the housing 101. The crushing rollers 102 are rotatably mounted on the side wall of the housing 101 through bearings. A discharge hopper 103 is fixedly disposed at the lower end of the housing 101. The discharge hopper 103 communicates with the housing 101 below the crushing rollers 102 and is used to receive the crushed waste material.

[0022] Inside the housing 101, on opposite sides, are pusher plates 104 parallel to the axis of the crushing roller 102. The pusher plates 104 are positioned above the crushing roller 102, allowing the scrap metal bucket to fall into the housing 101 and be positioned between the two pusher plates 104. The pusher plates 104 can laterally limit and push the bucket. On opposite sidewalls of the housing 101 are displacement grooves 105 extending along the sliding direction of the pusher plates 104. The displacement grooves 105 accommodate the sliding of the side components of the pusher plates 104. A push-pull rod 106 is fixedly connected to the side of the pusher plate 104, passing through the displacement groove 105 and extending to the outside of the housing 101.

[0023] A push-pull mechanism is provided on the outer side of the housing 101 corresponding to each push-pull rod 106, which is used to drive the pusher plate 104 to perform reciprocating linear motion, so that the pusher plate 104 periodically pushes the scrap iron bucket in the biting direction of the crushing roller 102, thereby preventing the scrap iron bucket from rolling and lingering between the side walls of the housing 101.

[0024] The support 100 is provided with fixed rods 107, which are fixedly connected to the support 100. A striking mechanism is provided between the fixed rods 107 for striking the discharge hopper 103. The striking mechanism can strike the discharge hopper 103 so that the crushed scrap iron drum fragments can be discharged smoothly, improving the discharge efficiency and the continuous working performance of the equipment.

[0025] Please see Figures 2-3 In this embodiment, the push-pull mechanism includes a sliding plate 200 fixedly installed on the outer wall of the housing 101. The sliding plate 200 has a groove 201 inside, and a movable groove 202 communicating with the groove 201 is opened on the sliding plate 200. A slidable slider 203 is provided inside the groove 201, and a vertical plate 204 is fixedly installed on the slider 203. The vertical plate 204 extends through the movable groove 202 and is fixedly connected to the push-pull rod 106. A cover 205 is provided opposite to the side of the housing 101, and the cover 205 is fixedly connected to the housing 101. A rotating rod 206 is installed inside the cover 205 via bearings, and both ends of the rotating rod 206 extend from both sides of the cover 205. A rotating disk 207 is fixedly installed at one end of the rotating rod 206 near the vertical plate 204. An eccentric column 208 is fixedly installed on the rotating disk 207. A connecting column 209 is fixedly installed on the vertical plate 204. The eccentric column 208 and the connecting column 209 are hingedly connected by a connecting rod 210.

[0026] In this embodiment, when the rotating rod 206 rotates and drives the rotating disk 207 to rotate, the eccentric column 208 drives the connecting rod 210 to push the vertical plate 204 to make reciprocating linear motion. The vertical plate 204 then drives the push-pull rod 106 and the pusher plate 104 to move back and forth, which can push the scrap iron bucket towards the biting direction of the crushing roller 102.

[0027] In this embodiment, a dual-axis motor 211 is fixedly installed between the oppositely arranged covers 205. The output shaft of the dual-axis motor 211 is fixedly connected to two rotating rods 206 respectively, which is used to drive the two rotating rods 206 on the same side to rotate, so that the pusher plate 104 makes a pushing motion, thereby realizing continuous pushing and limit control of the scrap iron drum.

[0028] Please see Figure 4 In this embodiment, a drive motor 300 is fixedly mounted on the outside of the housing 101. One of the crushing rollers 102 is the driving roller, whose shaft end extends axially through the side wall of the housing 101 and is connected to the output end of the drive motor 300 via a coupling. The drive motor 300 provides torque to the driving roller, causing it to rotate. A meshing gear structure is provided between the other end of the driving roller and the other crushing roller 102 (driven roller). The driven roller is driven by the driving roller, realizing the synchronous counter-rotation of the two rollers, that is, the two crushing rollers 102 move towards each other, clamping and shearing the scrap iron drum.

[0029] In this embodiment, the striking mechanism includes a rotating shaft 301 disposed between the fixed rods 107. The rotating shaft 301 is mounted between the fixed rods 107 via bearings. One end of the rotating shaft 301 extends from the side of the fixed rods 107, and a driven sprocket 302 is fixedly mounted on its extended end. A driving sprocket 303 is fixedly mounted on the extended shaft end of the driving roller. The driving sprocket 303 and the driven sprocket 302 are connected by a chain 304, so that the rotating shaft 301 rotates synchronously when the driving roller rotates.

[0030] A striking bar 305 (made of soft, wear-resistant material, such as a rubber strip or an elastic composite material strip) is fixedly provided on the rotating shaft 301. The striking bar 305 can periodically strike the outer wall of the discharge hopper 103 as the rotating shaft 301 rotates, causing the debris accumulated on the inner wall of the discharge hopper 103 to fall off, preventing residual material from adhering to the inner wall of the discharge hopper 103, and preventing the discharge hopper 103 from becoming clogged.

[0031] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
