Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to an energy-saving crusher with multi-stage crushing chambers. Background Technology

[0002] Crushers are devices that crush solid materials through compression, impact, shearing, and other methods. They are widely used in mining, construction, metallurgy, and other fields. They can process large materials into crushed materials that meet particle size requirements. Multi-stage crushing chamber crushers are advanced models. Their core feature is the integration of multiple crushing chambers of different sizes. The material passes through the coarse crushing, medium crushing, and fine crushing chambers in sequence. This design reduces material transfer links, lowers energy consumption, and improves crushing efficiency. It is especially suitable for complex crushing scenarios that require multiple particle sizes to be produced.

[0003] Existing multi-stage crushing chambers suffer from a lack of screening mechanisms during the stone input stage, making it impossible to effectively classify the stone at the initial stage of material entry. When mixed-size stone is fed into the inlet, small stones that should enter the next small-gap crushing chamber are instead fed into the first-stage crushing chamber equipped with large-gap crushing rollers, along with larger stones, due to the lack of pre-screening. These large-gap crushing rollers are designed to handle large stones, but the small stones create meaningless squeezing and friction between the rollers. On the one hand, the small stones repeatedly slide on the roller surface, accelerating the wear of the roller's wear-resistant layer and shortening the replacement cycle of the crushing rollers. On the other hand, the ineffective crushing action not only consumes extra power but also encroaches on the crushing space for large stones, resulting in a decrease in the equipment's throughput per unit time. At the same time, the repeated crushing of small stones in the large-gap rollers easily forms irregular fragments that mix with qualified stone, reducing the overall quality of the finished product and severely restricting the application of the equipment in high-efficiency, low-consumption crushing scenarios.

[0004] Therefore, it is necessary to invent an energy-saving crusher with multi-stage crushing chambers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving crusher with multi-stage crushing chambers to solve the problem mentioned in the background art of existing multi-stage crushing chambers lacking a screening mechanism during the stone feeding stage. This results in the inability to effectively classify the stone material at the initial stage of material entry. When mixed-size stone is fed into the inlet, small stones that should enter the lower-stage small-gap crushing chamber, due to the lack of pre-screening, enter the upper-stage crushing chamber equipped with large-gap crushing rollers along with larger stones. These large-gap crushing rollers are designed to handle large stones; however, the small stones create meaningless squeezing and friction between the rollers. On one hand, the small stones repeatedly slide on the roller surface, accelerating the wear of the roller's wear-resistant layer and shortening the replacement cycle of the crushing rollers. On the other hand, the ineffective crushing action not only consumes extra power but also occupies the crushing space for large stones, leading to a decrease in the equipment's throughput per unit time. Simultaneously, the repeated crushing of small stones in the large-gap rollers easily forms irregular fragments that mix with qualified stone, reducing the overall quality of the finished product and severely restricting the equipment's application in high-efficiency, low-consumption crushing scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving crusher with a multi-stage crushing chamber, including a crushing box, screening boxes symmetrically arranged on both sides of the crushing box, a vibrating motor fixedly connected to the outer side of the screening box, an inclined screen plate arranged above the inner side of the screening box, a horizontal screen plate fixedly connected to one side of the inclined screen plate, and a baffle plate arranged below the inclined screen plate. An installation plate is fixedly connected to one side of the inclined screen plate, and the installation plate is fixedly connected to the inside of the screening box. A bearing block is symmetrically fixedly connected to the side of the screening box, and the horizontal screen plate is fixedly connected to the top of the bearing block.

[0007] As a preferred embodiment, the crushing box is symmetrically provided with a first feed chute on both sides, and a second feed chute is provided at the bottom of the first feed chute. The horizontal screen plate and the inclined screen plate are provided corresponding to the first feed chute, and the baffle is provided corresponding to the second feed chute.

[0008] As a preferred embodiment, the inner side of the crushing box is symmetrically and fixedly connected with inclined guide grooves, and a crushing roller is arranged below the inclined guide grooves. The inner side of the crushing box is provided with two sets of inclined guide grooves and crushing rollers, and a discharge chute is opened at the bottom of the crushing box.

[0009] As a preferred embodiment, the bottom of the screening box is provided with a support plate, and two support plates are symmetrically arranged, with one end of the support plate fixedly connected to the side of the crushing box.

[0010] As a preferred embodiment, the inner side of the support plate is slidably connected to an installation block, and both ends of the installation block are fixedly connected to sliders. The two ends of the inner side of the support plate are provided with sliding grooves, and the sliders are slidably connected to the inner side of the sliding grooves.

[0011] As a preferred embodiment, the mounting block has a mounting hole on its inner side, the screening box has a hole at its bottom corresponding to the mounting hole, the screening box is fixedly connected to the top of the mounting block by bolts, and a spring is provided on one side of the mounting hole.

[0012] The technical effects and advantages of this utility model are as follows: This utility model features symmetrically arranged screening boxes on both sides of a crushing box. A vibrating motor is installed on the outside of the screening box, which can effectively drive the screening box to vibrate left and right. A horizontal screen plate and an inclined screen plate are installed on the inside of the screening box, which can effectively screen the stones put into the screening box. Smaller stones can pass directly through the inclined screen plate and the horizontal screen plate, while larger stones enter the inside of the crushing box for subsequent crushing. This effectively screens the stones and improves the subsequent crushing effect. This utility model features a support plate at the bottom of the screening box, with a mounting block slidably connected to the inner side of the support plate. The mounting block has mounting holes on its inner side, which effectively fixes the screening box to the top of the mounting block. A spring is provided on one side of the mounting block, which allows the screening box to swing left and right on the top of the support plate. At the same time, the spring effectively prevents the screening box from colliding with the crushing box and increases the swinging effect of the screening box. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see the appendix Figure 1 - Appendix Figure 4 An energy-saving crusher with a multi-stage crushing chamber includes a crushing box 1, screening boxes 2 are symmetrically arranged on both sides of the crushing box 1, a vibrating motor 21 is fixedly connected to the outside of the screening box 2, an inclined screen plate 26 is arranged above the inside of the screening box 2, a horizontal screen plate 22 is fixedly connected to one side of the inclined screen plate 26, and a baffle 25 is arranged below the inclined screen plate 26. The baffle 25 has a similar structure to the horizontal screen plate 22 and the inclined screen plate 26. An installation plate 23 is fixedly connected to one side of the inclined screen plate 26. The installation plate 23 is fixedly connected to the inside of the screening box 2. A bearing block 24 is symmetrically fixedly connected to the side of the screening box 2. The horizontal screen plate 22 is fixedly connected to the top of the bearing block 24.

[0017] Specifically, screening boxes 2 are symmetrically arranged on both sides of the crushing box 1. A vibrating motor 21 is installed on the outside of the screening box 2, which can effectively drive the screening box 2 to vibrate left and right. A horizontal screen plate 22 and an inclined screen plate 26 are installed on the inside of the screening box 2, which can effectively screen the stone material put into the screening box 2. Smaller stones can pass directly through the inclined screen plate 26 and the horizontal screen plate 22, while larger stones enter the inside of the crushing box 1 for subsequent crushing. This can effectively screen the stone material and improve the subsequent crushing effect.

[0018] Please see the appendix Figure 2 The crushing box 1 has a first feed chute 11 symmetrically opened on both sides, and a second feed chute 12 is opened at the bottom of the first feed chute 11. The horizontal screen plate 22 and the inclined screen plate 26 are correspondingly set with the first feed chute 11, and the baffle 25 is correspondingly set with the second feed chute 12.

[0019] Specifically, by setting a first feeding trough 11, a horizontal screen plate 22 is set at the top of the first feeding trough 11, so that the stones that do not fall from the inclined screen plate 26 and the horizontal screen plate 22 will enter the inner side of the first feeding trough 11 for subsequent crushing. The stones that fall from the horizontal screen plate 22 and the inclined screen plate 26 fall onto the baffle plate 25. The baffle plate 25 is set above the second feeding trough 12, and the screened small stones enter the second feeding trough 12 along the baffle plate 25, which facilitates the subsequent crushing work.

[0020] Please see the appendix Figure 2The inner side of the crushing box 1 is symmetrically and fixedly connected with inclined guide grooves 14. A crushing roller 13 is provided below the inclined guide grooves 14. Two sets of inclined guide grooves 14 and crushing rollers 13 are provided on the inner side of the crushing box 1. A discharge chute 15 is opened at the bottom of the crushing box 1.

[0021] Specifically, by setting inclined guide troughs 14, two sets of which are respectively set on one side of the first feed trough 11 and the second feed trough 12, the stones sliding down from the first feed trough 11 and the second feed trough 12 can be effectively guided, so that the stones can fall just above the crushing roller 13, preventing the stones from sliding down the side of the crushing roller 13 and improving the subsequent crushing effect. By setting the crushing roller 13, the crushing roller 13 is rotatably set inside the crushing box 1. The rear end of the crushing box 1 is equipped with a motor to drive the crushing roller 13 to rotate and complete the subsequent crushing work. There are two sets of crushing rollers 13, which can crush large stones and small stones respectively. Large stones falling from the first feed trough 11 are crushed by the upper crushing roller 13, and small stones entering from the second feed trough 12 are crushed by the lower crushing roller 13. This effectively improves the crushing effect, reduces the wear on the upper crushing roller 13, and reduces energy loss.

[0022] Please see the appendix Figure 1 and Figure 4 The bottom of the screening box 2 is provided with a support plate 3. There are two support plates symmetrically arranged. One end of the support plate 3 is fixedly connected to the side of the crushing box 1. The inner side of the support plate 3 is slidably connected with an installation block 32. Both ends of the installation block 32 are fixedly connected with sliders 33. The inner ends of the support plate 3 are provided with grooves 31. The sliders 33 are slidably connected to the inner side of the grooves 31. The inner side of the installation block 32 is provided with an installation hole 35. The bottom of the screening box 2 is provided with a hole corresponding to the installation hole 35. The screening box 2 is fixedly connected to the top of the installation block 32 by bolts. A spring 34 is provided on one side of the installation hole 35.

[0023] Specifically, by setting a support plate 3, which is fixedly connected to the side of the crushing box 1, and a screening box 2 is set at the top of the support plate 3 and slidably connected to the top of the support plate 3, a mounting block 32 is slidably connected to the inner side of the support plate 3, and a mounting hole 35 is provided on the inner side of the mounting block 32. The bottom end of the screening box 2 is provided with a hole corresponding to the mounting hole 35. The screening box 2 is fixedly connected to the top of the mounting block 32 by bolts, so that the screening box 2 can move with the sliding of the mounting block 32. Two mounting blocks 32 are symmetrically arranged on the inner side of the support plate 3, which effectively improves the stability of the installation of the screening box 2. By setting a sliding groove 31, the slider 33 can be slidably connected to the inner side of the sliding groove 31, which effectively improves the stability of the installation of the screening box 2. The stability of the sliding of the slider 33 and the mounting block 32 within the bearing plate 3 is achieved by setting a spring 34. The spring 34 is located within the bearing plate 3 and is positioned close to the crushing box 1. When the mounting block 32 slides with the screening box 2 within the bearing plate 3, the screening box 2 will move closer to the crushing box 1. The setting of the spring 34 can effectively prevent the screening box 2 from colliding with the crushing box 1. During the process of the screening box 2 moving towards the crushing box 1, the mounting block 32 will compress the spring 34, causing the spring 34 to contract, thereby buffering the impact force of the screening box 2. At the same time, when the spring 34 releases its elastic force, it can also effectively increase the shaking force of the screening box 2, effectively shaking the stone material set in the screening box 2.

[0024] The working principle of this utility model is as follows: When in use, the stone is poured into the screening box 2, and the vibration motor 21 is started to drive the screening box 2 to shake left and right. The stone falling on the horizontal screen plate 22 and the inclined screen plate 26 is shaken left and right. Smaller stones will fall directly onto the lower baffle 25 along the horizontal screen plate 22 and the inclined screen plate 26, while larger stones will slide into the inner side of the first feed chute 11 along the horizontal screen plate 22 and the inclined screen plate 26, and enter the upper crushing roller 13 for crushing along the inclined guide chute 14. The small stones at the lower baffle 25 enter the inclined guide chute 14 along the second feed chute 12, and enter the lower crushing roller 13 for crushing along the inclined guide chute 14. This can effectively screen the stone and improve the subsequent crushing effect.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
