Description

Technical Field

[0001] The invention relates to the technical field of crushing, and in particular to a crushing device for scrap metal parts. Background Art

[0002] Scrap metal can also be reused, such as being put into a smelting furnace for re-smelting processing. In order to reduce the space occupied by scrap metal during transportation and storage, and also to speed up the smelting speed during smelting, the scrap metal is generally crushed. After crushing, the space occupied can be reduced, and the small fragments are also convenient for being put into the smelting furnace for rapid smelting. At present, crushing devices are usually used to crush scrap metal, but the traditional crushing device has a feed port directly connected to the outside world, so the dust generated during crushing flies into the air through the feed port, affecting the working environment.

[0003] To solve the above problems, a Chinese patent with publication number CN208018484U discloses a scrap metal crushing, recycling, diversion and stirring device, which relates to the field of medical technology.

[0004] The following problems exist during the actual use of the above patent: scrap metal is crushed by alloy crushing blades to obtain crushed metal materials; but the sizes of the crushed metal materials vary, that is, the scrap metal is crushed unevenly; when the size of the crushed metal materials is larger than the inlet of the pipeline, the crushed metal materials will be retained at the bottom of the scrap metal crushing chamber, and then the inlet of the pipeline will be blocked, so that the crushed metal materials cannot be discharged, resulting in the inability to reuse the scrap metal. Summary of the invention

[0005] The present invention aims to provide a crushing device for scrap metal parts to solve the problem of uneven crushing of scrap metal by existing recycling devices.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a crushing device for scrap metal parts, comprising a processing box, a rotating shaft and a driving mechanism for driving the rotating shaft to rotate, a plurality of crushing blades are equidistantly arranged on both sides of the rotating shaft along the axial direction of the rotating shaft, and a feed port and a discharge port are arranged on the processing box; vertical grooves are arranged on the inner walls of both sides of the processing box, vertical blocks are arranged in the vertical grooves, and a flip shaft is connected to the vertical block, and the vertical block and the flip shaft can move vertically in the vertical grooves; a plurality of flipping plates are equidistantly arranged on both sides of the flip shaft along the axial direction of the flip shaft; a partition is arranged in the processing box, and a plurality of screening holes are arranged on the partition along the length direction of the partition, and the flipping plate is located between the crushing blade and the partition; a mesh box with an open top is arranged on both sides of the processing box, and the top of the mesh box is against the partition; a circular shaft is rotatably connected to the mesh box, and a crushing roller is coaxially connected to the circular shaft; it also includes a power mechanism that drives two vertical blocks to reciprocate vertically at the same time as the rotating shaft rotates, and a linkage mechanism that drives two circular shafts to rotate at the same time as the rotating shaft rotates.

[0007] The principles and advantages of this solution are:

[0008] 1. In this scheme, during the rotation of the shaft, the shaft drives the crushing blade to rotate synchronously, and the crushing blade is used to perform preliminary crushing treatment on the scrap metal to obtain metal waste, thereby reducing the volume of the scrap metal and preparing for easier crushing treatment later.

[0009] 2. In this scheme, the metal waste falls onto the surface of the partition. If the size of the metal waste is smaller than the size of the screening hole, the metal waste will fall into the mesh box through the screening hole; if the size of the metal waste is larger than the size of the screening hole, the metal waste will remain on the surface of the partition; during the rotation of the shaft, the power mechanism can simultaneously drive the two vertical blocks to reciprocate vertically, and the vertical blocks drive the flipping plates to reciprocate vertically through the flipping shaft, and then the metal waste on the surface of the partition can be driven to move vertically upward through the flipping plates, that is, the metal waste is driven to move in the direction of the crushing blade, and the crushing blade is used to crush it again, so that the size of the metal waste is smaller than the size of the screening hole, and then all the metal waste can enter the mesh box through the screening hole for re-crushing, which improves the utilization rate of the scrap metal and ensures the uniform crushing of the scrap metal.

[0010] 3. During the rotation of the shaft of this scheme, the linkage mechanism can simultaneously drive the two circular shafts to rotate, and the circular shaft drives the crushing roller to rotate, and the crushing roller is used to crush the metal waste in the mesh box to obtain metal particles; the metal particles of qualified size fall to the bottom of the processing box through the mesh box, and the metal particles of unqualified size are retained in the mesh box and are crushed again by the crushing roller, so that all the metal waste can be converted into metal particles of qualified size, which ensures the uniform crushing of the scrap metal.

[0011] Furthermore, the flip shaft is rotatably connected to the vertical block; a rack is provided in the vertical groove, and a gear meshing with the rack is coaxially connected to the flip shaft.

[0012] Through the above arrangement, while the vertical block drives the flip shaft to move vertically back and forth, the flip shaft drives the gear to move synchronously, the gear and the rack mesh to drive the gear to rotate, the gear drives the flip shaft to rotate, and the flip shaft drives the flip plate to rotate, and then the position of the metal waste can be continuously changed through the rotating flip plate, so as to drive the metal waste at different positions to move in the direction of the crushing blade, and use the crushing blade to crush it again, so that the size of all metal wastes can be smaller than the size of the screening hole.

[0013] Furthermore, the power mechanism includes a cylindrical cam coaxially connected to the rotating shaft, a slide groove vertically opened on the inner walls of both sides of the processing box, and a chamber vertically opened inside both sides of the processing box, and a curved groove is provided on the side wall of the cylindrical cam; the slide groove is located above the vertical groove, and a slider is slidably connected in the slide groove, and the end of the slider away from the slide groove is slidably connected to the curved groove; the chamber is communicated with the slide groove and the vertical groove, the vertical block passes through the chamber and is fixedly connected to the slider, and the vertical block can move vertically in the chamber.

[0014] Through the above arrangement, during the rotation of the shaft, the shaft will also drive the cylindrical cam to rotate, and the slider is restricted by the curved groove to reciprocate vertically along the path of the slide groove; during the vertical reciprocating motion of the slider, the slider drives the vertical block to reciprocate vertically.

[0015] Furthermore, a baffle for shielding the vertical groove is provided on the vertical block, and the baffle is in frictional contact with the side of the chamber close to the inside of the processing box; a through hole is provided on the baffle, and the flip shaft passes through the through hole, and the flip shaft can rotate in the through hole.

[0016] Through the above arrangement, during the vertical reciprocating motion of the vertical plate, the vertical plate drives the baffle to move synchronously, so that the baffle can always cover the vertical slot, preventing metal waste from entering the chamber through the vertical slot, allowing all metal waste to enter the mesh box through the screening holes, thereby improving the utilization rate of metal waste.

[0017] Furthermore, the rotating shaft is rotationally connected to the partition; the linkage mechanism includes a driving bevel gear coaxially connected to the rotating shaft and a driven bevel gear coaxially connected to the circular shaft, and the driving bevel gear is meshed with the driven bevel gear.

[0018] Through the above arrangement, during the rotation of the shaft, the shaft drives the active bevel gear to rotate, and the active bevel gear meshes with the driven bevel gear to drive the circular shaft to rotate.

[0019] Furthermore, guide grooves are vertically arranged on both sides of the net box, a screening net is slidably connected in the guide grooves, and a spring is arranged between the screening net and the guide grooves; a bottom groove is arranged at the bottom of the net box; and an extrusion mechanism is also included which intermittently squeezes the two screening nets as the rotating shaft rotates.

[0020] Through the above arrangement, metal particles of qualified size fall to the bottom of the processing box through the screening net, and metal particles of unqualified size are retained on the screening net.

[0021] During the rotation of the shaft, the two screening nets can be intermittently squeezed by the squeezing mechanism, so that the top block squeezes the screening net to move upward, and the spring is compressed. During the upward movement of the screening net, the metal particles with unqualified sizes can be driven to approach the crushing roller, and the crushing roller is used to crush them again, so that all the metal waste can be converted into metal particles with qualified sizes, which ensures the uniform crushing of the scrap metal;

[0022] When the squeezing effect of the squeezing mechanism on the two screening nets disappears, the screening nets move downward under the action of the springs; therefore, the screening nets can achieve vertical reciprocating motion; and, during the downward movement of the screening nets, the screening nets will also collide with the guide grooves, causing the screening nets to vibrate, thereby preventing metal particles from clogging the screening nets.

[0023] Furthermore, the extrusion mechanism includes wall grooves opened on both sides of the inner wall of the processing box and inclined grooves opened on both sides of the inner wall of the processing box. A wall block is slidably connected in the wall groove. A top groove is vertically provided on the top of the wall block. A top block extending into the bottom groove is slidably connected in the top groove. The spacing between the two inclined grooves gradually decreases from top to bottom. An auxiliary block is slidably connected in the inclined groove. The auxiliary block is fixedly connected to the top block, and the screening net is on the movement trajectory of the top block. It also includes an extrusion part that drives the two wall blocks to move horizontally at the same time as the rotating shaft rotates.

[0024] Through the above arrangement, during the rotation of the rotating shaft, the extrusion part can simultaneously drive the two wall blocks to move horizontally; when the wall block moves toward the side wall of the processing box, the wall block drives the top block to move synchronously, and at the same time, the top block will move upward under the guidance of the inclined groove, so that the top block squeezes the screening net to move upward, and the spring is compressed; when the wall block moves toward the middle direction of the processing box, the wall block drives the top block to move synchronously, and at the same time, the top block will move downward under the guidance of the inclined groove, so that the squeezing effect of the top block on the screening net disappears, and then the screening net moves downward under the action of the spring; therefore, the screening net can realize vertical reciprocating motion.

[0025] Furthermore, a plurality of bristles extending into the screening net are arranged on the wall block along the length direction of the wall block.

[0026] Through the above arrangement, during the horizontal reciprocating motion of the wall block, the wall block will also drive the bristles to synchronously reciprocate horizontally, that is, the bristles are used to clean the screening holes from the horizontal direction to avoid clogging of the screening net; and, during the horizontal reciprocating motion of the wall block, the screening net will reciprocate vertically, so that the bristles can continuously enter and exit the screening net, that is, the bristles are used to clean the screening holes from the vertical direction to avoid clogging of the screening net; in addition, the bristles continuously enter and exit the screening net, which can prevent metal particles from adhering to the bristles and improve the recovery rate of metal particles.

[0027] Furthermore, the extrusion part includes a C-shaped frame and an extrusion cam coaxially connected to the rotating shaft. The two sides of the C-shaped frame are respectively fixed to the two wall blocks. The extrusion cam abuts against the two sides of the C-shaped frame at the same time, and the extrusion cam can rotate in the C-shaped frame.

[0028] Through the above arrangement, during the rotation of the shaft, the shaft will also drive the extrusion cam to rotate, the extrusion cam drives the C-shaped frame to reciprocate laterally, and then the C-shaped frame drives the two wall blocks to reciprocate laterally at the same time.
