Description

Technical Field

[0001] This utility model relates to the technical field of coal conveying systems, specifically to an adjustable crushing and removal device. Background Technology

[0002] Crusher toothed rollers are a crucial component in the mining, processing, and use of various materials. Crushing is an essential step for coal to meet the needs of stakeholders, and only materials with the required particle size can be crushed for daily use. A four-toothed roller crusher utilizes four high-strength, wear-resistant toothed rollers rotating inwards to hard-crush materials, achieving the crushing purpose through bending and splitting. Traditional crushers consist of a main frame, power unit, working unit, retraction device, and conveyor belt. Material falls from above the distributor via the conveyor belt and enters the toothed rollers at both ends, where it is crushed by the pressure of the rollers to meet user requirements.

[0003] As a key component in crushing, the toothed roller of a crusher is subjected to tremendous impact and wear during use. Traditional methods of removing the toothed roller often require multiple steps and coordinated operations, which are cumbersome and time-consuming. Due to the large weight and size of the toothed roller, it is easy to cause accidental injury to maintenance personnel during removal. Long-term downtime for maintenance also increases production costs. In view of the above problems, a toothed roller removal device is designed to simplify the various impacts generated during the removal of the toothed roller, reduce safety risks and production costs.

[0022] Example 1

[0023] Please see Figures 1-3 This utility model provides a technical solution: an adjustable crushing and removal device, including a material hopper 1, an electrically adjustable distributor 3, a guide pipe 2, a toothed roller, a crusher body, a removal device 4, and a movable track 5. The electrically adjustable distributor 3 is installed at the bottom of the material hopper 1. The guide pipe 2 is connected to the bottom of the material hopper 1 and positioned below the electrically adjustable distributor 3, with both sides of the guide pipe 2 being fully enclosed. The toothed roller is mounted on the crusher body. One side of the movable track 5 is provided for the removal device 4 to be moved to a maintenance position. When material falls from the material hopper 1, it falls onto the electrically adjustable distributor 3. The electrically adjustable distributor 3 can be adjusted by rotating and tilting components to evenly distribute the material in a designated area. The electrically adjustable distributor 3 greatly reduces the impact of material falling from a height and the dust generated when the material rebounds. When the material falls into the guide pipe 2, the fully enclosed structure on both sides effectively prevents leakage and scattering of material during transportation. The guide pipe 2 helps and effectively solves the problems of on-site environmental cleanliness and safety. When a certain toothed roller needs maintenance, the bases of the toothed rollers on both sides are removed, and the bearings of the toothed rollers at both ends are locked. This removal device 4 uses an electric drive shaft wheel to move up and down. The power source is provided by the motor and transmitted to the drive shaft wheel through gear transmission to realize the lifting and lowering movement of the toothed roller.

[0024] 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.

[0025] As an embodiment of this utility model, the material hopper 1 is further equipped with an adjustable grate plate with an opening. The electric adjustable feeder 3 includes a rotating component and a tilting component, both of which are located on the inner wall of the material hopper 1. The two ends of the toothed roller are engaged with toothed roller bearings. The removal device 4 includes an electric drive shaft wheel, a motor, and a gear transmission structure. The output end of the motor is connected to the electric drive shaft wheel through the gear transmission structure. Both ends of the removal device 4 are equipped with first limit devices 6, with the detection end of the first limit device 6 facing the side of the electric drive shaft wheel. The bottom of the removal device 4 is equipped with casters 7. Both ends of the movable track 5 are equipped with second limit switches 8, with the detection end of the second limit switches 8 facing the removal device 4. The first limit devices 6 are installed at the top and bottom of the mechanism. These switches are used to detect the trajectory of the drive shaft wheel. When the shaft wheel reaches the specified upper or lower limit, the first limit switch 6 signal is triggered, which facilitates the automatic stop of the motor and prevents the gear from running beyond the limit. The bottom of the removal device 4 is equipped with casters 7, which can move in various directions. By controlling the forward and reverse rotation of the motor, the direction of the resultant force can be changed, thereby realizing the translation and direction change of the platform.

[0026] Specifically, the working principle of this adjustable crushing and removing device is as follows: The adjustable grate installed in the material hopper 1 controls the flow rate and particle size of the material. By adjusting the opening size of the grate, the speed and quantity of material passing through can be changed, thus achieving precise material control. After falling from the material hopper 1, the material falls onto the electrically adjustable distributor 3. The electrically adjustable distributor 3 can be adjusted by rotating and tilting components to evenly distribute the material in a designated area. The electrically adjustable distributor 3 greatly reduces the impact of material falling from a height and the dust generated when the material rebounds. When the material falls into the guide pipe 2, the two sides adopt a fully enclosed structure, effectively preventing leakage and scattering of material during transportation. The guide pipe 2 helps and effectively solves the problem of on-site environmental cleanliness and safety. When a certain stage of toothed roller needs maintenance, the bases of the two toothed rollers are removed, and the bearings of the two toothed rollers at both ends are locked. This removing device 4 uses an electrically driven shaft wheel to move up and down. The power source is provided by a motor, and the power is transmitted to the drive shaft wheel through gear transmission, realizing the lifting and lowering movement of the toothed roller. First limit devices 6 are installed at the top and bottom of the mechanism. These switches are used to detect the trajectory of the drive shaft wheel. When the shaft wheel reaches the specified upper or lower limit, the first limit switch 6 is triggered, which allows the motor to stop automatically and prevents the gear from running beyond its limit. The bottom of the removal device 4 is equipped with casters 7, enabling movement in various directions. By controlling the forward and reverse rotation of the motor, the direction of the resultant force is changed, thereby achieving platform translation and directional changes. After the toothed roller is removed from the crusher body, the removal device 4 moves to the maintenance position on the movable track 5. Second limit switches 8 are installed at both ends of the track to monitor the movement range of the removal device and ensure that it moves within the set area.
