Description

Technical Field

[0001] The utility model relates to a crushing and sorting device, in particular to a crushing and sorting device which is convenient for replacing a filter frame. Background Art

[0002] Stones are often needed in construction projects. Due to the large size of the stones, they usually need to be crushed, so a crushing and sorting device is needed.

[0003] For example, the Chinese patent publication number CN219984807U discloses a crushing and sorting device for construction engineering, which includes a crushing box, a sorting frame and a material receiving frame. The inner surface of the crushing box is rotatably connected with a driving drum and a driven drum. The outer surfaces of the driving drum and the driven drum are fixedly connected with a plurality of crushing teeth. The sorting trough is provided with a sorting frame inside, and a double-axis motor is fixedly installed on the top outer surface of the mounting frame. The crushing and sorting device for construction engineering crushes stones by setting a driving drum and a driven drum in conjunction with crushing teeth, and sorts the stones by the sorting frame, which solves the problem that the current traditional construction engineering operation crushes the stones by a crusher, and then screens them by a screening machine, and then transports the crushed stones to the screening machine for screening, which increases the work procedures and the labor intensity of the staff.

[0004] Some problems were found during the use of the above-mentioned existing crushing and sorting equipment for construction projects. First, after the stones are crushed, they fall into the horizontally arranged sorting frame, and some of the stones will accumulate inside the sorting frame, resulting in long-term accumulation of stones inside the sorting frame, which will affect normal screening and require manual cleaning at regular intervals. While consuming a lot of manpower, it will result in low screening efficiency. Secondly, when screening stones of different diameters, it is impossible to quickly replace sorting frames of different apertures. Utility Model Content

[0005] The purpose of the utility model is to provide a crushing and sorting device to solve the existing problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crushing and sorting device, comprising two brackets, a crusher is arranged above the brackets, limiting slide grooves are provided on the opposite surfaces of the two brackets, and a sorting frame is slidably installed in the limiting slide grooves, a motor is fixedly installed at the back of one of the brackets, a transmission disk is fixedly installed at the output end of the motor, a transmission shaft is fixedly installed at a position near the edge of one side of the transmission disk, two threaded connection holes are provided below the sorting frame, a threaded connector is threadedly installed in the threaded connection hole, and a limiting column is fixedly installed at the lower end of the threaded connector.

[0007] Preferably, a leg is fixedly mounted under the bracket.

[0008] Preferably, a diverter grid is fixedly installed between the two brackets and above the sorting frame.

[0009] Preferably, a support column is fixedly installed under the pulverizer, and the lower end of the support column is fixedly connected to the bracket.

[0010] Preferably, limiting sliders are fixedly installed on both sides of the sorting frame, the limiting sliders cooperate with the limiting sliding grooves, and a screen is embedded in the sorting frame.

[0011] Preferably, a hexagonal nut is fixedly mounted on the lower end of the limiting column.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting the sorting frame at an angle and opening a discharge port at the end, starting the motor to drive the transmission shaft to rotate, the transmission shaft and the limit column cooperate with each other to drive the sorting frame to reciprocate. The reciprocating motion of the sorting frame will screen the internal raw materials, and some of them will fall from the front end as the screening continues. Compared with the existing device, it can effectively avoid the problem of raw materials constantly accumulating directly inside the sorting frame and requiring manual cleaning.

[0014] 2. When it is necessary to screen raw materials of different diameters, you can use a wrench or other tools to rotate the hexagonal nut. The rotation of the hexagonal nut can drive the limit column to rotate, so that the threaded connector can be unscrewed from the inside of the threaded connection hole and the limit column can be removed. At this time, the connection between the sorting frame and the transmission shaft can be released. The sorting frame can be directly pulled out of the limit chute, which is convenient for replacing the sorting frame with different screens and inserting it into the limit chute to sort raw materials of different diameters.

[0015] 3. The diverter grid can disperse the concentrated falling raw materials to avoid the accumulation of raw materials dropped from the crusher in one place, which can effectively improve the sorting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a crushing and sorting device, including two brackets 1, a crusher 2 is arranged above the bracket 1, and limiting slide grooves 102 are provided on the opposite surfaces of the two brackets 1. A sorting frame 4 is slidably installed in the limiting slide grooves 102, a motor 3 is fixedly installed behind one of the brackets 1, a transmission disk 301 is fixedly installed at the output end of the motor 3, a transmission shaft 302 is fixedly installed at a position near the edge of one side of the transmission disk 301, and two threaded connection holes 403 are provided below the sorting frame 4, a threaded connection head 501 is threadedly installed in the threaded connection hole 403, and a limiting column 5 is fixedly installed at the lower end of the threaded connection head 501.

[0023] In this embodiment, the stone can be initially crushed by starting the crusher 2, and the crushed stone will fall from the lower discharge port to the sorting frame 4. The sorting frame 4 is tilted and has a discharge port at the end. The starting motor 3 drives the transmission disk 301 to rotate. The rotation of the transmission disk 301 can drive the transmission shaft 302 to rotate. The two limit columns 5 clamp the transmission shaft 302 in the middle. The rotation of the transmission shaft 302 can drive the limit columns 5 to move. The movement of the limit columns 5 will drive the sorting frame 4 to reciprocate, thereby screening the raw materials that fall on the sorting frame 4. Since the sorting frame 4 is tilted, the raw materials retained above the sorting frame 4 will slide down from the front end of the sorting frame 4 as the sorting frame 4 vibrates and slides down, and no manual cleaning is required.

[0024] Among them, in order to achieve the purpose of increasing the sorting efficiency, the present device is implemented by adopting the following technical solutions: a support leg 101 is fixedly installed under the bracket 1, a diverter grille 103 is fixedly installed between the two brackets 1 and above the sorting frame 4, a support column 201 is fixedly installed under the crusher 2, and the lower end of the support column 201 is fixedly connected to the bracket 1.

[0025] The support legs 101 support the bracket 1 at a suitable height to facilitate the collection of raw materials screened from below the sorting frame 4. The diverter grille 103 can disperse the concentrated raw materials to avoid the accumulation of raw materials crushed and dropped from the grinder 2 in one place, which can effectively increase the sorting efficiency.

[0026] Among them, in order to achieve the purpose of removing the limit column 5, the present device is implemented by the following technical scheme: the limit sliders 401 are fixedly installed on both sides of the sorting frame 4, the limit sliders 401 cooperate with the limit slide grooves 102, the sorting frame 4 is embedded with a screen 402, and the lower end of the limit column 5 is fixedly installed with a hexagonal nut 502.

[0027] The limiting slider 401 cooperates with the limiting slot 102 to limit the selection frame 4 to slide only along the limiting slot 102. The hexagonal nut 502 facilitates the use of a wrench to manually rotate the limiting column 5. The rotation of the limiting column 5 can drive the threaded connector 501 to rotate, so that the limiting column 5 can be easily removed. At this time, the selection frame 4 is not restricted by the transmission shaft 302 and can be directly pulled out from the limiting slot 102.

[0028] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, the raw materials are placed into the grinder 2, the grinder 2 is started to perform preliminary crushing on the raw materials, the crushed raw materials will be discharged from the lower end discharge port, the crushed raw materials will be dispersed through the diverter grille 103 and then fall into the sorting frame 4, the motor 3 is started to drive the transmission shaft 302 to rotate, the transmission shaft 302 cooperates with the limit column 5, and can drive the sorting frame 4 to reciprocate, the reciprocating movement of the sorting frame 4 will screen the internal raw materials, and a part of them will slide continuously from the front end as the screening The remaining part will fall down, and the other part will directly pass through the screen 402. When it is necessary to screen raw materials of different diameters, the hexagonal nut 502 can be rotated with a wrench or other tools. The rotation of the hexagonal nut 502 can drive the limiting column 5 to rotate, so that the threaded connector 501 can be screwed out from the inside of the threaded connection hole 403, and the limiting column 5 can be removed. At this time, the connection between the sorting frame 4 and the transmission shaft 302 can be released, and the sorting frame 4 can be directly pulled out from the limiting slide groove 102, which is convenient for replacing the sorting frame 4 with different screens 402 and inserting it into the limiting slide groove 102, so as to sort raw materials of different diameters.
