Description

Technical Field

[0001] This utility model relates to the technical field of cleaning devices for mining truck parts, and in particular to a cleaning device for a plate filter of a wide-body mining truck. Background Technology

[0002] Wide-body mining car transportation is a common mining technology used in open-pit mines. The complex environment of high dust and high fly ash in open-pit mines poses a huge challenge to cleaning the ventilation panel filters in the cab of wide-body mining cars. The ventilation panel filters in the vehicle cab are prone to clogging, which not only poses a huge challenge to the maintenance and use costs of the vehicle, but also harms the health of the vehicle driver.

[0003] In existing technologies, plate filters can be cleaned by high-pressure airflow impact. However, the large impact can easily cause deformation or damage to the plate filter. Another method is to clean plate filters using a V-groove deep dust suction cleaner, as described in application number 202011382960.0, which is less prone to deformation. This cleaner uses a suction nozzle that fits the V-groove shape of the filter screen to ensure even suction across the filter screen, allowing for better cleaning of the bottom of the V-groove. However, for plate filters with different structures, the V-shaped structure of the filter element is not the same, meaning the bending angle is not the same. The required V-shaped suction nozzle must match the V-groove shape of the filter screen to limit its application range. Utility Model Content

[0004] The purpose of this utility model is to provide a cleaning device for a wide-body mining truck plate filter. By continuously adjusting the vibration amplitude and frequency of the clamping mechanism through the cooperation of the vibration motor and vibration transmission components, different pollutants in the plate filter can be resonated and discharged within one working process from the start to the stop of the vibration motor, thereby improving the cleaning efficiency of the plate filter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a wide-body mining truck plate filter cleaning device, comprising:

[0006] The bracket has a working cavity.

[0007] The clamping mechanism has a clamping cavity for clamping a plate filter, and at least its lower end face has a through hole communicating with the clamping cavity and the outside.

[0008] A vibration drive mechanism includes a vibration motor and multiple vibration transmission components. The vibration motor is mounted on the clamping mechanism via a mounting plate. The vibration transmission components include a support column, a limiting pressure plate, a connecting plate, and an elastic element. The support column is fixed to the clamping mechanism. The limiting pressure plate is located at the upper end of the support column. One side of the connecting plate is fixed to the bracket, and the other side has a vertical hole. The vertical hole allows the plate to slide up and down onto the support column. The elastic element is fitted onto the support column, and its upper and lower ends abut against the limiting pressure plate and the connecting plate, respectively.

[0009] As a further optimization, the clamping mechanism includes a lower plate, an upper plate, and multiple connecting rods. The lower plate and the upper plate are connected by the connecting rods, and the clamping cavity is formed between them. The upper plate and the lower plate are respectively formed with through holes. The arrangement of the lower plate and the upper plate can facilitate the installation and positioning of the plate filter.

[0010] As a further optimization, the connecting rod includes a base rod and a bolt. The base rod is disposed on the lower plate, and the lower end face of the upper plate abuts against the upper end face of the base rod. The bolt passes through the upper plate and is locked inside the base rod, which can facilitate the fixed connection between the upper plate and the lower plate.

[0011] As a further optimization, the support column includes a base column and a top column disposed at the upper end of the base column. The limiting pressure plate is disposed on the top column, and the connecting plate and the elastic element are both sleeved on the top column. The vertical projection of the top column is located within the vertical projection of the base column, and the vertical projection of at least part of the outline of the vertical hole is located within the vertical projection of the base column, which can realize the support and limiting of the connecting plate.

[0012] As a further optimization, the limiting pressure plate includes a top plate and a nut. The upper part of the top post is provided with external threads. The top plate is sleeved on the top post and abuts against the upper end of the elastic element. The nut is screwed onto the top post and abuts against the upper end of the top plate.

[0013] As a further optimization, a limiting ring is provided at the lower end of the top plate. The limiting ring is sleeved on the outside of the top column and located on the inside of the elastic member.

[0014] As a further optimization, a bushing is provided on the connecting plate at the vertical hole, and the lower end of the elastic element abuts against the bushing.

[0015] As a further optimization, the elastic element is a spring.

[0016] As a further optimization, the clamping mechanism has a quadrilateral structure, and there are four vibration transmission components, which are respectively arranged at the corners of the clamping mechanism to ensure the balance of vibration of the clamping mechanism.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By cooperating with the vibration motor and vibration transmission components, the vibration amplitude and frequency of the plate filter located in the clamping mechanism are changed.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 4As shown, a cleaning device for a wide-body mining truck plate filter includes a bracket 10, a clamping mechanism 20, and a vibration drive mechanism 30. The bracket 10 has a working chamber 100. The clamping mechanism 20 has a clamping cavity 200 for clamping the plate filter, and at least its lower end face has a through hole connecting the clamping cavity 200 to the outside, such as a lower through hole 210 connecting the clamping cavity 200. The vibration drive mechanism 30 includes a vibration motor 31 and multiple vibration transmission components 32. The vibration motor 31 is mounted on the clamping mechanism 20 via a mounting plate 311, preferably mounted on the clamping mechanism. The upper end of 20 does not interfere with the lower through hole 210. The vibration transmission component 32 includes a support column 321, a limiting pressure plate 322, a connecting plate 323 and an elastic element 324. The support column 321 is fixed on the clamping mechanism 20. The limiting pressure plate 322 is set on the upper end of the support column 321. One side of the connecting plate 323 is fixed on the bracket 10, and the other side is provided with a vertical hole (not shown). The vertical hole can slide up and down and is sleeved on the support column 321. The elastic element 323 is sleeved on the support column 321, and its upper and lower ends abut against the limiting pressure plate 322 and the connecting plate 323 respectively.

[0027] In this utility model, combined with Figure 5As shown, after the plate filter 40 is removed from the wide-body mining truck (such as the YTK89A wide-body mining truck), it needs to be cleaned, that is, the impurities and contaminants that have entered the plate filter 40 from the working surface 400 side are removed from the plate filter 40. The plate filter 40 is fixed by the clamping mechanism 20, and the plate filter 40 is placed in the clamping cavity 200 with its working surface 400 facing downward. The working surface 400 is exposed to the outside due to the presence of the lower through hole 210. The vibration motor 31 may have a double eccentric block mechanism, its working voltage is DC24V, and its rated power is 150W. When powered, the vibration motor 31 starts to work, and the vibration force is transmitted to the clamping mechanism 20 through the mounting plate 311. Since the clamping mechanism 20 is connected to the bracket 10 through the vibration transmission assembly 32, and the vibration transmission assembly 32 has an elastic element 324, the elastic element 324 is preferably a spring. The elastic element 324 has the function of elastic compression and deformation recovery, which can form The up-and-down floating effect causes the plate filter 40 in the clamping mechanism 20 to vibrate as well. The vibration transmission component 32 generates relative displacement with the support 10 through the floating action. In the initial stage of the large inertia vibration motor 31, the elastic element 324 amplifies the amplitude generated by the vibration motor 31 and at the same time reduces the vibration frequency of the vibration motor 31. As the speed of the vibration motor 31 increases, the amplitude amplified by the elastic element 324 is gradually reduced, and the vibration frequency gradually increases. When the vibration motor 31 stops working, the effect is reversed. Based on the above vibration process, and since there are different pollutants on the plate filter 40, each pollutant has its own inherent frequency. During one cycle of the vibration motor 31 starting and stopping, its amplitude and frequency are infinitely adjustable, which can adapt to the frequency of different pollutants, thereby forming a resonance effect with different pollutants. This can maximize the vibration of different pollutants and discharge them from the working surface 400 of the plate filter 40 and fall through the lower through hole 210.

[0028] Preferably, to match the structure of the plate filter 40, the clamping mechanism 20 of this utility model has a quadrilateral structure, and there are four vibration transmission components 32. The four vibration transmission components 32 are respectively arranged at the corners of the clamping mechanism 20 to ensure the balance of vibration.

[0029] This invention achieves changes in the vibration amplitude and frequency of the plate filter 40 located in the clamping mechanism 20 through the cooperation of the vibration motor 31 and the vibration transmission component 32. It can achieve resonance of different pollutants and discharge them from the plate filter 40 within one working process from the start to the stop of the vibration motor 31, thereby improving the cleaning efficiency of the plate filter 40 and extending its service life.

[0030] To facilitate the positioning of the plate filter 40 within the clamping mechanism 20, the clamping mechanism 20 includes a lower plate 21, an upper plate 22, and multiple connecting rods 23. The lower plate 21 and the upper plate 22 are connected by the connecting rods 23, forming a clamping cavity 200 between them. A lower through hole 210 is formed on the lower plate 21, and an upper through hole 220 is formed on the upper plate. When cleaning the plate filter 40, it is placed on the lower plate 21, with its lower circumference abutting against the lower plate 21, and its working surface 400 facing the lower through hole 210. The upper plate 22 is placed against the upper end of the plate filter 40 and connected to the lower plate 21 by the connecting rods 23, thus fixing the plate filter 40 within the clamping cavity 200 formed between the upper plate 22 and the lower plate 21. The vibration motor 31 is fixed to the upper plate 22 by the mounting plate 311. The upper through hole 220 on the upper plate 22 enables its lightweight design. Both the lower plate 21 and the upper plate 22 can be made of Q235B low carbon steel and are formed by sheet metal bending and welding.

[0031] Furthermore, the connecting rod 23 includes a base rod 231 and a bolt 232. The base rod 231 is mounted on the lower plate 21, and the lower end face of the upper plate 22 abuts against the upper end face of the base rod 231. The bolt 232 passes through the upper plate 22 and is locked inside the base rod 231. The base rod 231 can provide auxiliary support for the upper plate 22 to facilitate the locking of the bolt 232, and can also limit the position of the upper plate 22 to prevent it from pressing too hard on the plate filter 40 and causing damage to the plate filter 40.

[0032] Preferably, the support column 321 includes a base column 3211 and a top column 3212 disposed at the upper end of the base column 3211. A limiting pressure plate 322 is disposed on the top column 3212. The connecting plate 323 and the elastic element 324 are both sleeved on the top column 3212. The vertical projection of the top column 3212 is located within the vertical projection of the base column 3211, and the vertical projection of at least part of the outline of the vertical hole is located within the vertical projection of the base column 3211. By sleeved on the thinner top column 3212, the connecting plate 323 can be supported and limited by the thicker base column 3211, thereby ensuring the overall vibration amplitude of the entire vibration transmission assembly 32.

[0033] Furthermore, the limiting pressure plate 322 includes a top plate 3221 and a nut 3222. The upper part of the top post 3212 is provided with external threads. The top plate 3221 is sleeved on the top post 3212 and abuts against the upper end of the elastic member 324. The nut 3222 is screwed onto the top post 312 and abuts against the upper end of the top plate 3221 to limit the top plate 3221.

[0034] In addition, a limiting ring 3220 is provided at the lower end of the top plate 3221. The limiting ring 3220 is sleeved on the outside of the top column 3212 and located on the inside of the elastic member 324. The limiting ring 3220 can fill the internal space of the elastic member 324 to a certain extent, ensuring that the deformation of the elastic member 324, like a spring, is only generated in the vertical direction when it is compressed.

[0035] A bushing 3231 is provided on the connecting plate 323 at the vertical hole. The bushing 3231 is made of polypropylene, and the lower end of the elastic element 324 abuts against the bushing 3231.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
