Description

Technical Field

[0001] This utility model relates to the field of stone crushing technology, and in particular to a stone crushing device. Background Technology

[0002] With globalization, large-scale infrastructure construction is underway in various regions, such as highways, railways, and bridges, which have led to a surge in demand for stone. As an important building material, the processing efficiency and quality of stone affect project progress and costs, prompting the research and development and application of high-efficiency stone crushing equipment.

[0003] Traditional crushing equipment can only produce finished products of the same size during the crushing process, and cannot obtain finished products of different sizes according to actual needs. This single-specification output mode of traditional equipment not only increases the cost of stone processing, but also causes material waste. Often, finished products of the same specification need to be processed again. If there are large metal blocks embedded or mixed in the stone, such as building stone, it is very easy for large metal blocks to be accidentally mixed in. During the crushing process, since the hardness of the metal blocks is much greater than that of the stone, this will cause the crushing rollers in the crushing equipment to bear excessive pressure, thereby causing damage to the crushing rollers.

[0004] In view of this, the present invention is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a stone crushing device in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stone crushing device includes a housing with a crushing mechanism inside. The housing includes an outer shell protecting the crushing mechanism, and two grooves are respectively opened on both sides of the outer shell. The crushing mechanism includes rollers installed on the inner walls of the two grooves on the corresponding side. Crushing rollers are fitted on the outer walls of the rollers. A driving mechanism is provided at one end of the rollers. The driving mechanism includes a sliding plate that slides on the surface of the outer shell. A shaft is installed on the surface of the sliding plate. A limit rod is movably installed between the shaft and the rollers. Displacement mechanisms are provided at both ends of the rollers to facilitate the movement of the crushing rollers. The displacement mechanisms include two axially driven threaded rods. Two sliders are threaded on the threaded rods. A buffer assembly for self-protection during crushing is installed on the other side of the threaded rods. The buffer assembly includes a buckle for limiting the movement. A spring for buffering is installed at one end of the threaded rods. A dust removal mechanism is provided on the outer wall of the housing.

[0008] Preferably, the housing includes a funnel-shaped inlet at the top of the outer shell and an outlet at the bottom of the outer shell.

[0009] Preferably, the roller is slidably disposed on the inner wall of the chute, and the inner wall of the outer shell is fixedly connected with corrugated blocks, which are alternately disposed with the crushing roller.

[0010] Preferably, a slide is fixedly connected to the outer wall of the housing, the slider slides inside the slide, and the roller is rotatably mounted on the slider. Each of the two threaded rods has a transmission clamp fixed at one end for mutual meshing and transmission, and a handle for rotating the threaded rod is installed at one end of the threaded rod.

[0011] Preferably, a motor is fixedly connected to the bottom of the slider, and a drive gear is fixedly installed at the output end of the motor via a coupling. A first gear is installed at one end of the shaft, and a second gear is installed at one end of the roller. The drive gear meshes with the second gear, and the first gear meshes with the second gear.

[0012] Preferably, a mounting base is fixedly connected to one side of the outer shell, a ring is installed on one side of the threaded rod, a spring is installed between the ring and the mounting base, a straight rod is provided through the inner wall of the spring and slides through the mounting base, and a limit block is installed on the outer wall of the straight rod.

[0013] Preferably, a pipe is connected to one side of the outer casing, an air pump is fixedly connected to one end of the pipe, and a filter box is fixedly connected to the other end of the air pump.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] During the stone crushing operation, the stone to be crushed is placed at the feed inlet of the equipment, and then the motor is started. The motor's operation will drive the drive wheel to start rotating. The rotation of the drive wheel is further transmitted to the gears that mesh with it, and finally acts on the crushing rollers, causing them to start rotating as well. When the stone passes through these rotating crushing rollers, it will be crushed due to the squeezing action on both sides of the crushing rollers. The entire crushing process is not only highly efficient, but also ensures the safety and reliability of the operation.

[0016] When faced with the demand for finished products of different particle sizes, turn the handle and drive the threaded rod to rotate. The transmission clamps at the opposite ends of the two threaded rods keep them rotating synchronously, causing the sliders on the two threaded rods to move in opposite directions. The movement of the sliders will drive the roller shaft to move, thereby causing the crushing rollers to move in tandem. This process changes the gap between the two crushing rollers, thereby realizing the adjustment of the particle size of the finished stone. Compared with the fixed spacing of the crushing rollers in traditional crushing equipment, the advantage of this equipment is that it can flexibly adjust the particle size of the finished product.

[0017] During the stone crushing process, if the stone contains hard metal blocks that prevent it from being crushed, the crushing roller will be displaced when squeezed by the metal blocks. This causes the buckle to deform and collapse. At this time, the transmission clamps in the middle of the threaded rod move away from each other and disconnect the transmission, causing the spring at one end of the corresponding threaded rod to contract. The metal block will then fall out of the gap, and the spring will rebound, pushing the buckle to reset, thus protecting the device from damage. This device can effectively protect itself from materials that cannot be crushed. Afterwards, a new buckle can be installed for reuse. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 - Figure 7 As shown, the present invention provides a stone crushing device, comprising a housing 10, and a crushing mechanism 20 disposed within the housing 10. The housing 10 includes a shell 12 protecting the operation of the crushing mechanism 20, and two grooves 24 are respectively opened on both sides of the shell 12. The crushing mechanism 20 includes rollers 23 installed on the inner walls of the two grooves 24 on the corresponding side. Crushing rollers 21 are sleeved on the outer wall of the rollers 23. A driving mechanism is provided at one end of the rollers 23. The driving mechanism includes a sliding plate 41 that slides on the surface of the shell 12, and a shaft is mounted on the surface of the sliding plate 41. 45. A limiting rod 42 is movably installed between the shaft 45 and the roller shaft 23. Both ends of the roller shaft 23 are provided with a displacement mechanism 30 to facilitate the movement of the crushing roller 21. The displacement mechanism 30 includes two axially driven threaded rods 32. Two sliders 33 are threaded on the threaded rods 32. A buffer assembly 35 for self-protection during crushing is installed on the other side of the threaded rods 32. The buffer assembly 35 includes a buckle 352 for limiting. A spring 353 for buffering is installed at one end of the threaded rods 32. A dust removal mechanism 50 is provided on the outer wall of the housing 10.

[0033] This solution uses a displacement mechanism 30. When faced with the demand for finished products with different particle sizes, the handle 31 is rotated, which drives the threaded rod 32 to rotate. The transmission clamps 34 at the opposite ends of the two threaded rods 32 keep them rotating synchronously, causing the sliders 33 on the two threaded rods 32 to move in opposite directions. The movement of the sliders 33 will drive the roller shaft 23 to move, thereby causing the crushing rollers 21 to move in tandem. This controls the spacing between the crushing rollers 21, enabling rapid adjustment of the spacing and effectively obtaining finished stone products with different particle sizes.

[0034] Specifically, such as Figure 1 As shown, the housing 10 includes a funnel-shaped inlet 11 at the top of the outer shell 12 and an outlet 13 at the bottom of the outer shell 12.

[0035] By setting the discharge port 13, the stone to be processed can be handled conveniently, saving labor costs and reducing frequent stone input. The discharge port 13 is designed to collect finished stone in a centralized manner, effectively preventing it from scattering.

[0036] Specifically, such as Figure 2As shown, the roller 23 is slidably disposed on the inner wall of the chute 24, and the inner wall of the outer shell 12 is fixedly connected with a corrugated block 22, which is staggered with the crushing roller 21.

[0037] By setting corrugated blocks 22, stone splashing during the crushing process can be effectively prevented, and stone fragments can be prevented from falling from the gap between the crushing roller 21 and the outer shell 12, ensuring a smooth crushing process.

[0038] Specifically, such as Figure 3 As shown, a slide 36 is fixedly connected to the outer wall of the outer casing 12, the slider 33 slides in the slide 36, and the roller shaft 23 is rotatably mounted on the slider 33. The two threaded rods 32 are fixed with transmission clamps 34 that mesh with each other at opposite ends, and a handle 31 for rotating the threaded rod 32 is installed at one end of the threaded rod 32.

[0039] By setting the transmission clamp 34, when the handle 31 is turned, the two threaded rods 32 can be precisely engaged and rotated together through the intermeshing transmission clamp 34, while ensuring that the two threaded rods 32 can be accurately reset to their original positions after separation.

[0040] Specifically, such as Figure 6 As shown, a motor 44 is fixedly connected to the bottom of the slider 33. A drive gear 46 is fixedly installed at the output end of the motor 44 through a coupling. A first gear 43 is installed at one end of the shaft 45, and a second gear 47 is installed at one end of the roller shaft 23. The drive gear 46 meshes with the second gear 47, and the first gear 43 meshes with the second gear 47.

[0041] Through the cooperation of the first gear 43 and the second gear 47, the motor 44 can drive the two crushing rollers 21 to rotate.

[0042] Specifically, such as Figure 5 As shown, a mounting base 355 is fixedly connected to one side of the outer casing 12, and a ring 351 is installed on one side of the threaded rod 32. A spring 353 is installed between the ring 351 and the mounting base 355. A straight rod 354 is provided through the inner wall of the spring 353, and the straight rod 354 slides through the mounting base 355. A limit block is installed on the outer wall of the straight rod 354.

[0043] By setting spring 353, when encountering hard metal blocks mixed in with the stone that cannot be broken, the crushing roller 21 will drive the roller shaft 23 to move when squeezed by the metal block. At this time, the transmission clamp 34 in the middle of the threaded rod 32 moves away from each other and disconnects the transmission, so that one end of the corresponding threaded rod 32 compresses the spring 353 to contract. The metal block will then fall out from the gap, and the spring 353 will rebound. The device can effectively achieve self-protection.

[0044] Specifically, such as Figure 3 As shown, a pipe 51 is connected to one side of the outer casing 12, an air pump 52 is fixedly connected to one end of the pipe 51, and a filter box 53 is fixedly connected to the other end of the air pump 52.

[0045] By installing filter box 53, various hazards caused by excessive dust can be avoided, thereby protecting people's health and the safety of the environment.

[0046] When using this solution, the air pump 52 is started to collect the dust in the housing 10 into the filter box 53. Then, the stone to be crushed is placed at the feed inlet 11. Subsequently, the motor 44 is started. The output end of the motor 44 will drive the drive wheel to rotate together through the coupling. The rotation of the drive wheel is further transmitted to the second gear 47 that meshes with it. Through the cooperation of the first gear 43 and the second gear 47, the two first gears 43 will drive the roller shaft 23 and thus drive the crushing roller 21 to rotate together. The stone is crushed by the pressure from the crushing rollers 21 on both sides. The final product flows out from the discharge port 13.

[0047] When faced with finished product requirements of different particle sizes, manually turn the two handles 31. The rotation of the handles 31 will drive the threaded rod 32 to rotate together. Since the threads on the threaded rod 32 are reversed, it can ensure that the two sliders 33 move in opposite directions. During the movement of the sliders 33, the internal roller shaft 23 will be displaced, and the crushing roller 21 will be displaced at the same time. The gap between the two crushing rollers 21 will increase (decrease). While the sliders 33 are moving, they will drive the first gear 43 to move together. Due to the presence of the limiting rod 42, the roller shaft 23 and the shaft body 45 will drive the slide plate 41 to move up and down, so that the gears always maintain a meshed state when the gap between them changes. At the same time, the motor 44 fixed below the slider 33 will also move to maintain the drive of the crushing roller 21.

[0048] When crushing stone, if hard metal blocks are mixed in the stone and cannot be crushed, the metal blocks will squeeze the crushing roller 21, and one side of the crushing roller 21 will move outward. The movement of the crushing roller 21 will drive the slider 33 on the threaded rod 32 to move, thereby causing the transmission clamp 34 at the opposite ends of the two threaded rods 32 to disengage. At the same time, the spring 353 will be compressed, causing the metal block to fall out of the gap. Then the spring 353 will rebound, driving the slider 33 and the threaded rod 32 to reset. The threaded rods 32 on both sides will fit together. Then the buckle 352 will be reinstalled to fix the two threaded rods 32 together.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
