Description
Technical Field
[0001] This utility model relates to the field of stone crushing technology, and in particular to a stone crusher for stone crushing technology. Background Technology
[0002] Crusher, a type of mechanical equipment used in stone crushing technology, is used to crush various ores, rocks, and other materials into crushed stones of different particle sizes. It is widely used in mining, construction, highways, railways, water conservancy, and other fields. Common types of crushers include jaw crushers, cone crushers, impact crushers, and cone crushers.
[0003] In document CN219702201U, a stone crusher for stone processing technology is described, comprising a base and a crusher body. The crusher body has an installation groove, within which a conveying device is installed. A washing mechanism is provided between the top of the base and the installation groove. However, in practice, the following drawbacks exist: when the stone material enters the crusher body from the feed hopper, the feed inlet remains connected to the crusher, allowing dust to escape to the outside; during power outages or when the electric push rod malfunctions, the feed hopper may remain connected to the crusher body and cannot be disconnected; the nozzles can only spray the crushed stone after crushing, not the stone being crushed, resulting in continued dust accumulation within the crusher body, affecting its normal operation.
[0004] Therefore, this application provides a stone crusher for stone crushing technology to meet the requirements. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a stone crusher for stone crushing technology to solve the problems of existing stone crushers where the outside world is connected to the crusher, or where the outside world may be connected to the inside of the crusher when there is a power outage or the electric push rod fails, and the nozzle cannot effectively reduce the dust inside the crusher.
[0006] To solve the problems mentioned above, this utility model is implemented through the following technical solution.
[0007] A stone crusher for stone crushing technology, comprising:
[0008] The main body and the enclosing mechanism disposed inside the main body;
[0009] The subject includes:
[0010] The feed inlet is located on the top side wall of the main body, allowing the stone to enter the interior of the main body;
[0011] The feeding channel is vertically opened on the inner side of the top of the main body, with its upper and lower ends located on the upper and lower sides of the feeding port and connected to the feeding port;
[0012] A crushing chamber is located at the bottom of the feed channel and is connected to the crushing chamber.
[0013] The enclosure mechanism includes:
[0014] A cylinder is fixedly connected to the top of the feed channel, with its output end pointing vertically downwards, and is used to drive the output end to move up and down.
[0015] The connecting bracket is fixedly connected to the output end of the cylinder;
[0016] A flap is rotatably connected to the bottom of the connecting frame;
[0017] A sealing element is provided at the bottom of the flap to seal the bottom of the feed channel.
[0018] Preferably, the main body further includes:
[0019] The crushing roller is rotatably connected to the crushing chamber and connected to the motor, and performs stone crushing work under the drive of the motor;
[0020] A screen is set at the bottom of the crushing chamber and fixedly connected to the inner wall of the main body for screening larger stone particles;
[0021] A storage bin, placed at the bottom of the screen, is used to store the stone material after it has been screened by the screen;
[0022] A conveyor belt is located at the bottom of one end of the screen near the outer side of the main body, and is used to transport large-volume stone materials after being screened by the screen.
[0023] The spraying device is fixedly connected to the outer sidewall of the main body and is used to provide water for dust suppression and cooling.
[0024] The nozzle is installed on the inner wall of the crushing chamber and is connected to the spraying device through a water pipe.
[0025] Preferably, the screen is inclined, tilting downwards towards the side closer to the conveyor belt.
[0026] Preferably, the nozzle is located above the crushing roller, with the water spray end pointing towards the crushing roller.
[0027] Preferably, the connecting frame includes:
[0028] A baffle is fixedly connected to the side of the connecting frame near the feed inlet, and is used to close the connection between the feed inlet and the feed channel;
[0029] A rotating shaft is fixed to the bottom of the connecting frame and is set as the rotating shaft of the flap.
[0030] A torsion spring, installed on the outside of the rotating shaft, is used to provide elastic force to the rotating shaft, so that it returns to its initial horizontal state when no external force is applied.
[0031] Preferably, the closure mechanism further includes:
[0032] The connector is in a vertical position, with its upper end fixedly connected to the connecting frame and its lower end fixedly connected to the sealing element, and is used to define the position of the connecting frame and the sealing element.
[0033] This utility model provides a stone crusher for stone crushing technology. Compared with the prior art, it has the following advantages:
[0034] 1. By setting up a sealing mechanism, the connecting frame, flap, and sealing components are moved up and down by a cylinder. Together with the baffle, the connection between the feed inlet and the feed channel is sealed. When the stone is fed, the opening or closing of the connection between the crushing chamber and the feed channel is controlled, thereby controlling the rhythm of the stone falling. The flap rotates at different angles according to the weight of the stone on top of it, preventing the feed inlet from being completely connected to the inside of the crushing chamber during the feeding process. This controls the degree of connection between the feed inlet and the crushing chamber during feeding and reduces the amount of dust emitted from the feed inlet during feeding.
[0035] 2. By installing a torsion spring on the outside of the rotating shaft at the bottom of the connecting frame, the torsion spring provides elasticity to the rotating shaft, so that the flap can return to its initial horizontal state when no external force is applied. Thus, in the event of a power outage or cylinder failure, the flap can remain horizontal by relying on the elasticity of the torsion spring without the need for electricity or other power. This, together with the sealing element, seals the bottom of the feed channel, preventing the outside from communicating with the inside of the crusher.
[0036] 3. By installing the nozzle on the inner wall of the crushing chamber and above the crushing roller, with the water spray end pointing towards the crushing roller, the dust-suppressing and cooling water provided by the spraying device is directly sprayed onto the crushing roller and the stone being crushed. Dust is suppressed at the source of dust generated during the stone crushing process. The adsorption property of water causes dust particles to agglomerate and settle, and the settled dust is carried away by the water, preventing dust from accumulating in the stone crusher.

[0046] Reference Figures 1-5 A stone crusher for stone crushing technology, comprising:
[0047] The main body 10 and the enclosed mechanism disposed inside the main body 10;
[0048] Main body 10 includes:
[0049] The feed inlet 11 is located on the top side wall of the main body 10, allowing the stone to enter the interior of the main body 10;
[0050] The feeding channel 12 is vertically opened on the inner side of the top of the main body 10, with its upper and lower ends located on the upper and lower sides of the feeding port 11 and connected to the feeding port 11;
[0051] Crushing chamber 13 is located at the bottom of feed channel 12 and is connected to crushing chamber 13;
[0052] The closed mechanism includes:
[0053] Cylinder 20 is fixedly connected to the top of feed channel 12, with its output end pointing vertically downward, and is used to drive the output end to move up and down.
[0054] The connecting bracket 21 is fixedly connected to the output end of the cylinder 20;
[0055] Flip plate 22 is rotatably connected to the bottom of connecting frame 21;
[0056] The sealing element 23 is located at the bottom of the flap 22 and is used to seal the bottom of the feed channel 12.
[0057] Furthermore, such as Figures 1 to 4 As shown, by moving the baffle 211, the flap 22 and the seal 23 up and down, the opening or closing of the connection between the crushing chamber 13 and the feed channel 12 is controlled, thereby controlling the falling rhythm of the stone. At the same time, when the crushing roller 14 is working, the connection between the feed channel 12 and the crushing chamber 13 can be closed to prevent dust and other particles in the crushing chamber 13 from moving to the outside through the feed inlet 11.
[0058] The main body 10 also includes:
[0059] The crushing roller 14 is rotatably connected to the crushing chamber 13 and connected to the motor, and performs stone crushing work under the drive of the motor;
[0060] Screen 15 is set at the bottom of crushing chamber 13 and fixedly connected to the inner wall of main body 10, and is used to screen larger stone particles;
[0061] The storage bin 16 is placed at the bottom of the screen 15 and is used to store the stone material after it has been screened by the screen 15.
[0062] Conveyor belt 17 is located at the bottom of one end of screen 15 near the outer side of the main body 10, and is used to transport large-volume stone materials after being screened by screen 15.
[0063] The spraying device 18 is fixedly connected to the outer sidewall of the main body 10 and is used to provide water for dust suppression and cooling.
[0064] Nozzle 19 is installed on the inner wall of crushing chamber 13 and is connected to spray device 18 through a water pipe.
[0065] Furthermore, such as Figure 2 and Figure 3 As shown, water is sprayed during the crushing process of the stone to reduce dust at the source of dust generation, improve the dust reduction effect, and carry away the settled dust with water to prevent dust from accumulating inside the main body 10.
[0066] The screen 15 is set at an angle, tilting downwards towards the side closer to the conveyor belt 17.
[0067] Furthermore, such as Figure 2 As shown, the crushed large stones slide along the inclined plane on the screen 15 due to gravity, avoiding accumulation on the screen 15, and finally fall onto the conveyor belt 17 to be transported to the outside of the main body 10.
[0068] The nozzle 19 is located above the crushing roller 14, with the water spray end pointing towards the crushing roller 14.
[0069] Furthermore, such as Figure 2 and Figure 3 As shown, water is sprayed directly at the source of the dust, and the adsorption properties of water cause dust particles to agglomerate and settle, thus suppressing dust generation at the source.
[0070] Connector 21 includes:
[0071] Baffle 211 is fixedly connected to the side of the connecting frame 21 near the feed inlet 11 and is used to close the connection between the feed inlet 11 and the feed channel 12.
[0072] The rotating shaft 212 is fixed to the bottom of the connecting frame 21 and is set as the rotating shaft of the flap 22;
[0073] Torsion spring 213, installed on the outside of rotating shaft 212, is used to provide elastic force to rotating shaft 212 and return it to its initial horizontal state when no external force is applied.
[0074] Furthermore, such as Figure 4 and Figure 5 As shown, the spring force of the torsion spring 213 ensures that the flap 22 remains horizontal when there is no external force, thereby maintaining the sealing state at the feed channel 12.
[0075] The closed mechanism also includes:
[0076] The connector 24 is in a vertical position, with its upper end fixedly connected to the connector 21 and its lower end fixedly connected to the seal 23, and is used to limit the position of the connector 21 and the seal 23.
[0077] Furthermore, such as Figure 4 As shown, this allows the connecting frame 21 and the seal 23 to move synchronously.
[0078] When the crusher is working, the stone material enters the feed channel 12 from the top feed inlet 11. The cylinder 20 drives the connecting frame 21 of the sealing mechanism to descend, so that the baffle 211 no longer blocks the connection between the feed inlet 11 and the feed channel 12, and also moves the sealing element 23 into the crushing chamber 13, connecting the feed channel 12 and the crushing chamber 13. At this time, the stone material enters the feed channel 12 from the feed inlet 11 and first falls onto the flap 22. The flap 22 rotates at a certain angle under the action of the stone material's mass, so that the stone material of the corresponding mass falls down into the crushing chamber 13 through the channel opened by the downward rotation of the flap 22. Since the flap 22 rotates according to the weight of the stone material on top of it, the greater the mass, the larger the volume of the stone material, and the larger the rotation angle. Moreover, the rotation angle of the flap 22 changes in real time according to the weight of the stone material on top of it, thus avoiding direct and complete connection between the feed inlet 11 and the inside of the crushing chamber 13 during the feeding process, reducing the degree of connection between the feed inlet 11 and the crushing chamber 13 during feeding. The motor drives the crushing roller 14 to rotate and crush the stone. The crushed stones fall onto the inclined screen 15. Small particles fall through the screen 15 into the storage box 16, while large particles slide along the inclined surface of the screen 15 to the conveyor belt 17 and are sent out. At the same time, the spraying device 18 supplies water to the nozzle 19 installed above the crushing roller 14 through the water pipe. The water sprays water to moisten the dust inside the crushing chamber 13. The sealing mechanism rises after feeding and uses the flap 22, the seal 23 and the baffle 211, which are restored to a horizontal state, to block the passage and prevent dust from overflowing.
