Description

Technical Field

[0001] This application relates to the field of sand and gravel processing technology, and more specifically, to a sand and gravel crushing device. Background Technology

[0002] Sand and gravel processing has a wide range of applications in construction, mining and other fields. In the sand and gravel processing process, freshly mined sand and gravel generally need to be crushed by sand and gravel crushing equipment to reach a certain size before subsequent processing steps can be carried out.

[0003] Most crushing equipment on the market is currently open-type. For example, Chinese patent (authorization announcement number CN220835770U) discloses a sand and gravel crushing device, which includes a main body with a feed inlet at the top and an adaptation adjustment mechanism installed below the feed inlet. A vibrating screen mechanism is installed below the adaptation adjustment mechanism, and a dust suppression mechanism is installed on the upper side of the main body. The adaptation adjustment mechanism includes a fixed crushing roller. The operator can start the drive motor in advance according to the volume of the sand and gravel to be processed. In this state, the transmission rod will drive the bevel gear set on both sides of the middle to rotate synchronously. The bevel gear set will drive the transmission screw to rotate. At this time, the screw sleeve driven by the transmission screw will move the upper baffle set on its inner side and the moving crushing roller horizontally, thereby adjusting the processing distance between the moving crushing roller and the fixed crushing roller on one side. After the adjustment is completed, the sand and gravel can be fed into the feed inlet at the top of the main body of the sand and gravel crushing device for adaptive processing.

[0004] Regarding the aforementioned technologies, the inventors believe that when crushing equipment encounters large sand or gravel during processing, or when sand or gravel is injected too quickly, it may accumulate at the feed inlet, affecting processing efficiency. Furthermore, the open design may cause sand or gravel to splash outwards during processing, posing certain safety hazards. Utility Model Content

[0005] To address the aforementioned problems, this application provides a sand and gravel crushing device.

[0006] The sand and gravel crushing device provided in this application adopts the following technical solution:

[0007] A sand and gravel crushing device includes a crushing chamber and an integrally formed feeding chamber on top of the crushing chamber. The feeding chamber is characterized by: spring hinges fixedly installed on both sides of the opening of the feeding chamber; two chamber covers are movably connected to the opening of the feeding chamber via the spring hinges; the two chamber covers are in the reset state of the spring hinges when closed; a drive motor is fixedly installed on one side of the feeding chamber at the top of the crushing chamber; the drive motor rotatably passes through one side wall of the feeding chamber and is connected to a first crushing roller; the other end of the first crushing roller is rotatably connected to the inner wall of the other side of the feeding chamber.

[0008] Furthermore, a drawer-type discharge hopper is fixedly installed at the bottom of the crushing chamber, and the discharge hopper is connected to the crushing chamber.

[0009] Furthermore, the discharge hopper is equipped with a sliding material trough that can be pulled outwards, and a viewing window is also provided in the middle of the discharge hopper.

[0010] Furthermore, two second crushing rollers are symmetrically arranged in the middle of the inner wall of the crushing chamber.

[0011] Furthermore, two pulleys are symmetrically arranged in the middle of the outer wall of the crushing chamber, and the two pulleys are respectively connected to the two second crushing rollers.

[0012] Furthermore, the first crushing roller is arranged laterally in the feed bin and is in the shape of a spiral blade. Two second crushing rollers are arranged longitudinally in the crushing bin on the same horizontal plane and are in the shape of a drum with protruding teeth on their outer walls.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. This application has a first crushing roller installed in the feed hopper. During processing, the drive motor drives the first crushing roller to rotate at high speed. When larger sand and gravel enters or sand and gravel are injected too quickly, the first crushing roller can break up the larger sand and gravel or disperse the accumulated sand and gravel, so as to avoid the accumulation of sand and gravel at the feed inlet and ensure processing efficiency. In addition, the hopper cover connected by the spring hinge is in the reset state of the spring hinge when closed. When the material is injected, it can automatically reset to a certain extent in real time. After the injection is completed, it can be completely reset and closed, blocking most of the sand and gravel that splashes outward during the processing, effectively reducing safety hazards.

[0015] 2. By fixing and installing a connected drawer-type discharge hopper at the bottom of the crushing chamber, and sliding outward-pulling material trough in the discharge hopper, and the discharge hopper also having a viewing window, it is convenient to observe that the material trough can be pulled out directly after it is full of material, which greatly facilitates the discharge, collection and transportation of finished products.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses a sand and gravel crushing device. Please refer to [link / reference]. Figure 1The system includes a crushing chamber 1 and an integrally formed feed chamber 2 on top of the crushing chamber 1. Spring hinges 3 are fixedly installed on both side walls of the opening of the feed chamber 2. Two chamber covers 4 are movably connected to the opening of the feed chamber 2 via the spring hinges 3. When closed, the two chamber covers 4 are in the reset state of the spring hinges 3. When the sand and gravel material to be crushed is injected, the chamber covers 4 can automatically and in real-time reset to a certain extent, greatly reducing the open area. After complete injection, they can be completely closed, thus blocking most of the sand and gravel splashed outwards during processing, effectively reducing... To eliminate safety hazards, a drive motor 5 is fixedly installed on one side of the feed bin 2 at the upper part of the crushing bin 1. The drive motor 5 rotatably passes through one side wall of the feed bin 2 and is connected to a first crushing roller 6. The other end of the first crushing roller 6 is rotatably connected to the other inner wall of the feed bin 2. When material is injected, the drive motor 5 drives the first crushing roller 6 to rotate at high speed. When larger sand and gravel enter or when sand and gravel are injected too quickly, the first crushing roller 6 can break up the larger sand and gravel or disperse the accumulated sand and gravel, so as to avoid the accumulation of sand and gravel at the feed inlet and ensure processing efficiency.

[0026] The lower part of the crushing chamber 1 is also fixedly installed with a drawer-type discharge chamber 7, which is connected to the crushing chamber 1. After being crushed and processed in the crushing chamber 1, the sand and gravel will fall directly into the discharge chamber 7.

[0027] The discharge bin 7 is equipped with a pull-out material trough 701 that can be slidably installed. The discharge bin 7 also has a viewing window 702 in the middle. After the material falls into the discharge bin 7, it will directly enter the material trough 701. After observing through the viewing window 702 that the material trough 702 is full of material, the material trough 702 can be pulled out directly, which brings great convenience to the discharge, collection and transportation of finished products.

[0028] Two second crushing rollers 101 are symmetrically arranged in the middle of the inner wall of the crushing chamber 1. After the material falls into the crushing chamber 1, the two second crushing rollers 101 complete the main crushing work.

[0029] Two pulleys 102 are symmetrically arranged in the middle of the outer wall of the crushing chamber 1. The two pulleys 102 are respectively connected to two second crushing rollers 101. The two second crushing rollers 101 are driven by the external drive equipment connected through the pulleys 102 to crush the sand and gravel at high speed.

[0030] The first crushing roller 6 is horizontally arranged in the feed bin 2. The first crushing roller 6 is in the shape of a spiral blade. The spiral blade shape of the first crushing roller 6 makes it easy to break up larger sand and gravel or disperse accumulated sand and gravel. The two second crushing rollers 101 are longitudinally arranged in the crushing bin 1 on the same horizontal plane. The second crushing rollers 101 are in the shape of a drum with protruding teeth on the outer wall, which can perform more comprehensive and thorough crushing of sand and gravel.

[0031] The implementation principle of the sand and gravel crushing device in this application embodiment is as follows: During use, the sand and gravel material to be crushed is injected into the feed bin 2. When the sand and gravel material to be crushed is injected, the bin cover 4 can automatically return to its original position to a certain extent in real time, which greatly reduces the open area. After the material is fully injected, it can be completely closed, thereby blocking most of the sand and gravel that splashes outward during the processing, effectively reducing safety hazards. When the material is injected, the drive motor 5 will drive the first crushing roller 6 to rotate at high speed. When larger sand and gravel enters or the sand and gravel is injected too quickly, the first crushing roller 6 can break up the larger sand and gravel or disperse the accumulated sand and gravel, avoiding the accumulation of sand and gravel at the feed inlet and ensuring processing efficiency. Then the material falls into the crushing bin 1, where the two second crushing rollers 101 complete the further and more detailed crushing work. Finally, after the material falls into the discharge bin 7, it will directly enter the material trough 701. After observing through the viewing window 702 that the material trough 702 is full of material, it can be directly pulled out of the material trough 702, which brings great convenience to the discharge, collection and transportation of finished products.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
