[0028] See also Figure 1-Figure 3 The present embodiment discloses an iron chip crusher, comprising a support frame 1 and an operating bin 2 connected to the support frame 1, wherein a feed hopper 3 is connected to the top of the operating bin 2, a crushing knife group 4 is arranged in the operating bin 2, and a discharge port 5 is arranged at the bottom of the crushing knife group 4. The iron chip mass to be crushed enters the operating bin 2 through the feed hopper 3, and is discharged through the discharge port 5 after being crushed by the crushing knife group 4.

[0029] It should be noted that the iron filings ball is formed by winding iron filings wires. Due to the mutual connection between the iron filings wires, it is often difficult for them to fall down by their own gravity. Therefore, the iron filings crusher provided in this embodiment also includes a material guiding mechanism 6 arranged in the working bin 2, which is used for auxiliary pushing of the iron filings ball, and pushes the iron filings ball at the feed port position to the crushing knife group 4.

[0030] Specifically, the working bin 2 is fixedly connected to the support frame 1, and includes a bin plate assembly for enclosing the working bin 2. The bin plate assembly includes two oppositely arranged vertical plates 21, and a first bin plate 22 and a second bin plate 23 respectively connected to both ends of the two vertical plates 21. The two vertical plates 21 cooperate with the first bin plate 22 and the second bin plate 23 to enclose the working bin 2 together.

[0031] The crushing blade group 4 includes a rotatable moving blade roller group and a non-rotatable fixed blade group, and the moving blade roller group and the fixed blade group cooperate to implement the crushing operation.

[0032] The fixed knife group is arranged on one side of the movable knife roller shaft 41, including a fixed knife seat 45 and a fixed knife serration 46 arranged at one end of the fixed knife seat 45. The two are preferably connected as one piece to ensure the stable setting of the fixed knife serration 46. The fixed knife serration 46 and the blade of the movable knife block 43 are engaged to play a crushing role. It can be understood that the fixed knife seat 45 should have a length matching the movable knife roller shaft 41 so that the arranged fixed knife serrations 46 can be engaged with the fixed knife blocks respectively.

[0033] The fixed blade seat 45 is fixedly connected to the first storage plate 22 or the second storage plate 23 on both sides, and is fastened by screws, so that the fixed blade serrations 46 can be replaced when they are worn. Preferably, in order to improve the crushing efficiency, in this embodiment, the fixed blade seat 45 is provided in two groups, which are respectively connected to the first storage plate 22 and the second storage plate 23. It can be understood that the first storage plate 22 and the second storage plate 23 are not vertically arranged, and their lower end portions extend in the direction close to the movable blade roller shaft 41, and the fixed blade seat 45 is respectively connected to the lower ends of the first storage plate 22 and the second storage plate 23.

[0034] Combination Figure 5 In this embodiment, the material guiding mechanism 6 includes a material guiding push plate 61, a material guiding driving member 62 and a transmission assembly 63. The output end of the material guiding driving member 62 is connected to the transmission assembly 63, and the material guiding push plate 61 is driven by the transmission assembly 63 to perform material guiding movement. The material guiding push plate 61 is attached to the inner wall of the first bin plate 22 or the second bin plate 23, and the movement trajectory of the material guiding push plate 61 is attached to the inner wall curve of the corresponding first bin plate 22 or the second bin plate 23. The following takes the first bin plate 22 as an example to specifically introduce the matching structure:

[0035] Combination Figure 1 and Figure 5The material guide drive member 62 includes two first drive cylinders respectively connected to the outer walls of the two vertical plates 21, one end of the first drive cylinder is hinged to the cylinder seat fixed to the outer wall of the vertical plate 21, and the transmission assembly 63 includes a first connecting rod 631 attached to the outer wall of the vertical plate 21 and a second connecting rod 632 attached to the inner wall of the vertical plate 21. The first connecting rod 631 and the second connecting rod 632 are connected by a rotating shaft 633, and the rotating shaft 633 passes through the vertical plate 21 and is rotatably connected to the vertical plate 21 through a bearing. Specifically, the other end of the first drive cylinder is hinged to one end of the first connecting rod 631 through a Y-shaped joint, and the other end of the first connecting rod 631 is fixed with a driving ring 634, which is sleeved on one end of the rotating shaft 633 and transmits the rotating torque through a key connection. The other end of the transmission shaft is fixedly connected to a follower shaft, and one end of the second connecting rod 632 is fixedly provided with a polygonal ring, which is sleeved on the follower shaft. The rotation of the rotating shaft 633 and the follower shaft drives one end of the second connecting rod 632 to rotate, and the other end of the second connecting rod 632 is fixedly connected to the above-mentioned material guiding push plate 61, and then the material guiding push plate 61 is driven by the first driving cylinder to make an arc-shaped material guiding movement in the direction of approaching or moving away from the crushing knife group 4.

[0036] In this embodiment, the cross section of the material guide push plate 61 is a triangular structure, and the end facing the feed hopper 3 is an acute angle. This structural setting can increase stability on the one hand, and can minimize the material carrying of the material guide push plate 61 during the return process on the other hand. Preferably, the bottom end of the material guide plate is provided with multiple sets of saw teeth, thereby increasing its friction, improving the material pushing effect, and preventing the material from slipping.

[0037] In order to fit the arc-shaped movement of the material guiding push plate 61 , in this embodiment, the first storage plate 22 on the same side as the material guiding push plate 61 is also constructed as an arc-shaped plate.

[0038] In this embodiment, by setting a guide mechanism 6 in the working bin 2, the iron filings can be pushed to move quickly toward the crushing knife group 4, thereby accelerating the crushing process, and the position setting of the guide mechanism 6 in the working bin 2 can effectively utilize the space and greatly save space occupation. Furthermore, the iron filings only move in the working bin 2 which is closed on all sides, and the crushed iron filings, oil stains, and waste liquid are discharged from the discharge port 5 for easy collection.

[0039] like Figure 3 As shown, in this embodiment, the discharge port 5 is constructed as a sloped slide, which is fixedly connected to the support frame 1 and corresponds to the bottom of the crushing knife group 4. The crushed material naturally falls onto the slide and is guided out of the equipment through the slide.

[0040] In another embodiment, the iron chip crusher further comprises a screen for screening the crushed material, the screen is coated on the middle and lower part of the moving knife roller shaft 41, and the crushed material falls on the screen and falls into the discharge port 5 through the screen. Preferably, see Figure 4 The screen further includes a first screen 71 and a second screen 72 that are connected to each other. The first screen 71 is fixedly connected to the bottom end of the first bin plate 22 through a mounting plate, and the connection method is preferably bolted, so that it can be disassembled and assembled according to actual needs. The second screen 72 is fixed by a support rib plate 73 that is roughly L-shaped. The top of the support rib plate 73 can be rotated so that the second screen 72 can be opened and closed as a whole, which is convenient for the staff to inspect or replace the moving knife block 43. Specifically, a rotating shaft 74 is fixed at the top of the support rib plate 73, and the rotating shaft 74 is rotatably connected between the two vertical plates 21. Correspondingly, the corresponding ends of the two vertical plates 21 are respectively fixedly connected with mounting blocks 75 by bolts. The rotating shaft 74 passes through the vertical plate 21 and is rotatably set in the through hole of the mounting block 75, and is respectively matched with the vertical plate 21 and the mounting block 75.

[0041] The top end of the supporting rib plate 73 roughly corresponds to the middle turning position of the second bin plate 23. The second screen 72 and the supporting rib plate 73 can also block the crushing operation area to prevent iron chips from splashing.

[0042] In this embodiment, in order to ensure the stable setting of the second screen 72 in the open state, the side end of the mounting block 75 is also connected with a fastening screw 76, and the fastening screw 76 passes through the side end of the mounting block 75. Correspondingly, a limiting hole adapted to the fastening screw 76 is provided on the rotating shaft 74. When the second screen 72 is opened to a predetermined position, the limiting hole and the fastening screw 76 are combined, and the fastening screw 76 is screwed into the limiting hole to limit the rotation position. Further, the two side ends of the support rib 73 are also hinged with a first limiting link 77, and the top end of the support frame 1 is hinged with a second limiting link 78 that cooperates with the first limiting link 77. The other ends of the first limiting link 77 and the second limiting link 78 are hinged to each other, and the hinged ends of the second limiting link 78 and the first limiting link 77 are fixed with a limiting bend 79. When the second screen 72 is opened, the first limiting link 77 will be driven to rotate accordingly, and the limiting bend 79 limits its rotation angle.

[0043] Based on the above embodiment, it is more preferred that, in order to prevent a large iron block from falling to the shearing position and causing the movable blade roller 41 to get stuck, the iron chip crusher further includes an opening and closing control mechanism 8, which is used to control the opening and closing of the fixed blade and the screen on the same side as the material guide push plate 61 to allow large pieces of material to pass through. In this embodiment, the first bin plate 22 further includes an upper plate body 221 and a lower plate body 222, and the lower plate body 222 is connected to the bottom end of the upper plate body 221.

[0044] For details, see Figure 3 , Figure 4 The opening and closing control mechanism 8 includes a rotating shaft 81 fixedly connected to the top of the lower plate body 222, and the rotating shaft 81 is rotatably connected between the two vertical plates 21. The connecting end of the lower plate body 222 is constructed as an arc structure that is compatible with the rotating shaft 81. The rotating shaft 81 provides support and rotation support for the lower plate body 222.

[0045] In this embodiment, the fixed knife seat 45 is fixedly connected to the side of the lower plate body 222 by screws, and the first screen 71 is fixedly connected to the bottom end of the lower plate body 222 by a mounting plate, so that the fixed knife seat 45 and the first screen 71 on this side can be driven to move synchronously by the rotation of the lower plate body 222. Correspondingly, the opening and closing control mechanism 8 further includes a second driving cylinder 82 for controlling the rotation of the lower plate body 222, and the second driving cylinder 82 is arranged on the other side of the lower plate body 222. In order to facilitate the fixing of the second driving cylinder 82, a square bracket 83 is also fixed between the two vertical plates 21 on the corresponding side, such as square steel, and the square bracket 83 and the corresponding side of the lower plate body 222 are respectively fixed with a support, and the output end and the fixed end of the second driving cylinder 82 are respectively hinged to the two supports. Then, the lower plate body 222 can be pulled to rotate by the extension and contraction of the second driving cylinder 82, and the fixed knife seat 45 and the first screen 71 on this side are driven to open and close at the same time.
