Description

Technical Field

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

[0002] Initially collected ore needs to be crushed before useful minerals can be extracted. During the ore crushing process, jaw crushers can efficiently crush large pieces of ore into the required size. A jaw crusher consists of two jaw plates (moving jaw plate and stationary jaw plate) and guard plates on both sides, forming a crushing chamber. It simulates the movement of an animal's jaws to complete the material crushing operation. The maximum compressive strength of the crushed material is 320 MPa.

[0003] During the operation of a jaw crusher, impurities often adhere to the jaw plates or guard plates, forming mud-like substances. Impurities, especially those adhering to the jaw teeth, can significantly hinder effective contact between the jaw plates and the ore, leading to a reduction in crushing speed. Removing and cleaning the jaw plates requires strict safety measures, including power outages (ensuring the equipment is completely stopped, disconnecting the power supply, and displaying warning signs), cooling equipment (if the equipment has just finished running, wait for it to cool to room temperature to avoid burns from hot components), and requiring personnel to wear protective gear. This cumbersome operation is detrimental to the continuous operation of the jaw crusher.

[0004] In the prior art, utility model patent CN222197048U discloses a crushing machine for ore. Through the cooperation of toothed plate one, toothed plate two, a fixed plate, an elastic mechanism, and a lifting mechanism, it cleans impurities adhering to the tooth surfaces of the stationary and movable jaw plates installed inside, without requiring disassembly for cleaning. However, the movable jaw plate, stationary jaw plate, and the left and right side guard plates are all wear parts. Over long-term use, their wear will inevitably reduce the overall crushing efficiency and may even prevent the crushing process from proceeding smoothly. Both the stationary and movable jaw plates need to be disassembled after a certain period of use, and relying solely on experience to judge the wear degree of the jaw teeth cannot guarantee that the crushing speed and effect will meet requirements. Therefore, there is an urgent need for a device that can clean impurities inside the jaw teeth while simultaneously monitoring the wear degree of the jaw teeth to solve the above problems. Utility Model Content

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0024] Example 1

[0025] As shown in the figure, a crushing machine for ore includes a crusher body 1 and a stationary jaw plate 2 and a movable jaw plate 3 disposed on the inner wall of the crusher body 1. Both the stationary jaw plate 2 and the movable jaw plate 3 are fixedly connected to the inner wall of the crusher body 1 by a pressure block 4. A control box 5 is disposed on the outer wall of the crusher body 1. The control box 5 contains a drive gear 6 and a driven rack 7 meshing with the drive gear 6. The drive gear 6 is connected to a drive device 8 and a power supply 9. A switch 10 and a warning light 11 are disposed on the outer wall of the control box 5. The switch 10 is electrically connected to the power supply 9.

[0026] A cleaning mechanism is provided between the stationary jaw plate 2 and the movable jaw plate 3. The cleaning mechanism includes a first toothed plate 12 and a second toothed plate 13. The top end of the driven rack 7 passes through the control box 5. The end of the driven rack 7 is fixedly connected to one end of the first toothed plate 12 via an L-shaped rod 14. The other end of the first toothed plate 12 is slidably connected to the inner wall of the crusher body 1 via a slider 15. A second spring assembly is provided at the end of the L-shaped rod 14 near the first toothed plate 12. The second spring assembly includes a U-shaped plate 16 disposed on the L-shaped rod 14, a connecting post 17 disposed on the first toothed plate 12, and a spring element 18 sleeved on the connecting post 17.

[0027] A monitoring mechanism is provided between the first toothed plate 12 and the second toothed plate 13. The monitoring mechanism includes an electric telescopic column 19 and a pressure sensor 20 disposed at one end of the electric telescopic column 19. Both the first toothed plate 12 and the second toothed plate 13 are fixedly connected to the pressure sensor 20 through a first spring assembly. The first spring assembly includes a top post 21 disposed on the pressure sensor 20 and a spring member 18 sleeved on the top post 21. The first toothed plate 12 is provided with a through hole 22 corresponding to the top post 21, and the top post 21 passes through the through hole 22, with the through end of the top post 21 flush with the tooth surface of the first toothed plate 12. The warning light 11 is electrically connected to the pressure sensor 20. Specifically, the control box 5 has a built-in processor that stores a range of manually preset electrical signals. When the pressure sensor 20 converts the pressure signal into an electrical signal and transmits the electrical signal to the processor, the processor determines whether the current electrical signal is within the range. If yes, the warning light 11 is in a green state; otherwise, the warning light 11 is in a red state.

[0028] Its working principle is as follows:

[0029] Based on the dimensions of the crusher body 1, the extension speed and distance of the electric telescopic column 19 and the rotational speed of the drive gear 6 are set to fixed values. During the operation of the crusher body 1, the cleaning mechanism is activated, and the electric telescopic column 19 retracts at a preset speed and distance. At the same time, the drive gear 6 drives the driven rack 7 to move downward at a preset speed, that is, drives the first toothed plate 12 and the second toothed plate 13 to move downward, scraping away impurities from the surfaces of the stationary jaw plate 2 and the moving jaw plate 3.

[0030] When the wear of the stationary jaw plate 2 and the moving jaw plate 3 is zero, the spring element 18 on the top column 21 is in a slightly compressed state. At this time, the through end of the top column 21 is flush with the tooth surface of the first tooth plate 12. During the operation of the crusher body 1, the spring element 18 on the top column 21 is in a slightly compressed state or frequently switches between compressed state with vibration. The work of scraping the impurities on the surface of the stationary jaw plate 2 and the moving jaw plate 3 is carried out according to the preset route. At this time, the electrical signal received and converted by the pressure sensor 20 is within the range and maintains dynamic balance, and the warning light 11 is in a green state.

[0031] When the wear of the stationary jaw plate 2 and the moving jaw plate 3 increases, the spring element 18 on the top column 21 is in a non-compression state. At this time, the through end of the top column 21 is higher than the tooth surface of the first tooth plate 12. During the operation of the crusher body 1, the spring element 18 on the top column 21 frequently switches between a non-compression state and a slightly compression state due to vibration. The work of scraping off impurities from the surface of the stationary jaw plate 2 and the moving jaw plate 3 is carried out according to the preset route. At this time, the electrical signal received and converted by the pressure sensor 20 will exceed the range value, and the warning light 11 will be in a red state. It is recommended to check or replace the stationary jaw plate 2 or the moving jaw plate 3.

[0032] Therefore, this utility model adopts the above-mentioned ore crushing machinery and equipment, which cleans the impurities in the jaw teeth and monitors the wear degree of the jaw teeth, making it convenient to replace the jaw plates regularly, ensuring the normal use of the stationary jaw plate and the moving jaw plate, and maintaining a high crushing efficiency of the crusher for a long time.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
