DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] See also Figures 1 to 5 , the present invention provides a technical solution:

[0034] A conveyor belt cleaning device includes a scraper assembly 1, a splitting assembly 2 and a material guide assembly 3, and the specific structural details are as follows:

[0035] The scraper assembly 1 is mounted on a base 6, wherein the base 6 is mounted on a transverse bracket in the conveyor, and the base 6 plays a role in supporting the entire cleaning device. The scraper member 10 in the scraper assembly 1 can always abut against the surface of the conveyor belt under the action of the return spring 12 to achieve the cleaning of the conveyor belt surface. The scraper assembly 1 includes the scraper member 10, a support seat 11, a return spring 12 and a mounting seat 13.

[0036] The scraper member 10 is installed on the support seat 11 by means of a support, and the lower end of the support seat 11 is slidably connected to the mounting seat 13 by means of a guide rod 14. The mounting seat 13 adopts a rectangular tube structure, and the reset spring 12 is sleeved on the guide rod 14 between the support seat 11 and the mounting seat 13. The lower end of the guide rod 14 is connected with a locking nut; under the action of the reset spring 12, the scraper member 10 can always abut against the surface of the conveyor belt.

[0037] In this embodiment, there are two groups of guide rods 14 symmetrically disposed at two ends of the support base 11 , and each group of guide rods 14 includes two guide rods 14 .

[0038] The splitting assembly 2 is installed on both sides of the scraper assembly 1. The splitting assembly 2 can split the adhesion layer on the surface of the conveyor belt by means of the splitting blades 21 therein. The splitting assembly 2 has two groups and is symmetrically arranged on both sides of the scraper assembly 1. The splitting assembly 2 includes a splitting frame 20, a splitting blade 21 and a transmission shaft 22.

[0039] The two dividing frames 20 are respectively installed on the two end sides of the support seat 11, and the transmission shaft 22 is installed between the two dividing frames 20 with the help of bearings. There are several dividing blades 21 and they are installed on the transmission shaft 22 at equal intervals. Considering the demand for lightweight, the dividing component 2 can be made of high-strength plastic, which can reduce some weight compared with traditional metal parts.

[0040] In this embodiment, the guide plate 30 includes a straight surface segment and a curved surface segment. The straight surface segment is connected to the cushion block 31 , and the curved surface segment is fixedly connected to the lower end of the straight surface segment.

[0041] The material guide assembly 3 is installed on both sides of the scraper assembly 1 and is used to guide the adhesive layer scraped off the conveyor belt surface to the waste collection box, and a vibration mechanism 4 that can assist the material guide assembly 3 in discharging is also arranged below the segmentation assembly 2. The material guide assembly 3 includes a material guide plate 30 and a hollow structure cushion block 31. The waste collection box is arranged below the material guide plate 30 (not shown in the figure);

[0042] The guide plate 30 is installed on the side of the support seat 11 by means of a cushion block 31 .

[0043] The vibration mechanism 4 includes a vibration member 40 and a transmission shaft 2 41;

[0044] There are several vibrating members 40 which are equidistantly arranged on the second transmission shaft 41. Both ends of the second transmission shaft 41 are mounted on the partition frame 20 by means of bearings. The vibrating member 40 includes a vibrating sleeve 400 and a swing rod 402. The vibrating sleeve 400 is fixed on the second transmission shaft 41 and an articulated seat 401 is arranged on the outer periphery of the vibrating sleeve 400. One end of the swing rod 402 is rotatably connected to the articulated seat 401.

[0045] The transmission shaft 1 22 is connected to the transmission shaft 2 41 by means of a transmission mechanism 5 .

[0046] In this embodiment, the transmission mechanism 5 includes a pulley 1 50, a pulley 2 51 and a transmission belt 52. One side of the transmission shaft 1 22 and the transmission shaft 2 41 extends to the outside of the dividing frame 20. The transmission shaft 1 22 is connected to the pulley 1 50 by means of a one-way bearing 53. The transmission shaft 2 41 is directly connected to the pulley 2 51. The pulley 1 50 and the pulley 2 51 are connected by means of a transmission belt 52.

[0047] In this embodiment, the two one-way bearings 53 work in opposite ways. When one of the transmission shafts 22 rotates in the forward direction, the transmission shaft 22 can drive the pulley 50 to rotate in the forward direction with the help of the one-way bearing 53, while the other transmission shaft 22 cannot drive the pulley 50 connected thereto to rotate. The following is a specific illustration. Figure 6 As shown, when the conveyor belt is transporting from left to right, the dividing blade 21 located on the left side of the scraper member 10 rotates in the positive direction (clockwise), and the transmission shaft 22 located on the left side can drive the pulley 50 to rotate synchronously with the help of the one-way bearing 53. At this time, the transmission shaft 22 located on the right side of the scraper member 10 cannot drive the pulley 50 to rotate because the one-way bearing 53 located on this side is in an unlocked state. Therefore, the vibration mechanism 4 located on the right side of the scraper member 10 cannot operate, and there is no adhesion layer on the guide plate 30 at this time, which can reduce the wear on the guide plate 30 and extend its service life. Conversely, when the conveyor belt is transporting from right to left, the vibration mechanism 4 located on the right side of the scraper member 10 operates, and the vibration mechanism 4 located on the left side cannot operate. Among them, Figure 7 Schematic diagram of the installation position of the cleaning device 100 and the conveyor 200 of the present invention.

[0048] The working principle of the present invention is as follows:

[0049] The conveyor belt will first contact the split blade 21 during the movement, and the adhesive layer attached to the surface of the conveyor belt will be cut into multiple pieces or segments by the split blade 21 to reduce the resistance during scraping, so that the adhesive layer can be easily scraped and cleaned when passing through the scraper member 10;

[0050] At the same time, the cleaned adhesion layer will be discharged into the waste collection box through the guide plate 30, and the transmission shaft 22 can drive the pulley 50 to rotate with the help of the one-way bearing 53, and then drive the vibration member 40 to rotate. The rocker arm 402 in the vibration member 40 is made of elastic plastic, which is bendable and can continuously hit the guide plate 30, thereby assisting in discharging.

[0051] Based on the above, the present invention sets a splitting component 2 on both sides of the scraper component 1, and can use the splitting component 2 to cut the block-shaped adhesion layer into multiple pieces before the scraper component 10 performs cleaning, so as to reduce the resistance during scraping and improve the cleaning effect; the present invention also optimizes the discharge structure of the traditional N-type sweeper, and sets a guide plate 30, which can guide the scraped adhesion layer into the waste collection box, and can also knock the guide plate 30 with the help of the vibration mechanism 4 to assist the guide plate 30 in discharging, so as to avoid the adhesion layer adhering to the guide plate 30 again and causing poor discharge.

[0052] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
