Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a belt conveyor cleaning device. Background Art

[0002] A belt conveyor is a conveying device for transporting bulk materials such as coal, ore, grain and other materials, in which the conveyor belt is used to carry the material.

[0003] However, during the use of the belt, materials may adhere to the conveyor belt due to moisture, stickiness or other reasons during transportation, causing the materials to be thrown to the return side of the conveyor. The materials are scattered on one side of the conveyor in a large range, which is inconvenient to clean. For this reason, we propose a belt conveyor cleaning device to solve the existing problem.

[0006] Preferably, the scraper is in the shape of an angled plate, and one end of the scraper is provided with equidistantly spaced cutting teeth, the upper end of the cutting teeth being lower than the upper end of the scraper. The cutting teeth avoid direct contact with the conveyor belt and cut the bulk material adhering to the lower end of the conveyor belt into multiple small pieces.

[0007] Preferably, the scraper is provided with sliders at both the front and rear ends, and the upper end of the base plate is provided with symmetrically distributed slide seats, and the sliders are slidably mounted inside the slide seats. The scraper slides inside the slide seats through the sliders, so that the scraper can move laterally.

[0008] Preferably, a travel hole is provided inside the support plate, and one end of the scraper is provided with a guide rod which slides through the spring and the travel hole. When the spring is extended or retracted, the guide rod slides inside the travel hole and is guided by the spring.

[0009] Preferably, the upper end of the bottom plate is provided with symmetrically distributed support seats, and the front and rear ends of the roller are rotatably plugged into the support seats. The roller is rotatably supported by the support seats and rotates below the belt conveyor.

[0010] Preferably, the two ends of the torsion spring are connected to the rotating seat and the rotating shaft respectively. When the rotating shaft rotates, the torsion spring provides torsional elastic support.

[0011] Preferably, a brush plate is provided on the upper end of the bottom plate, and scraping strips arranged in a rectangular array are provided at one end of the brush plate, and one end of the scraping strips corresponds to the brush. The brush plate is installed on the scraping strips, and the scraping strips peel off the material adhered to the brush passing through.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model installs a non-powered automatic roller at the belt head and below the unloading port of the conveyor belt. The driving force of the belt movement applies continuous pressure in one direction to the roller to drive the roller to rotate, and then the brush on the roller is used to clean the accumulated material on the belt. In order to avoid the brush on the outer wall of the roller applying a small brushing force on the belt, the rotating end of the roller is intermittently elastically supported by an elastic member. The intermittent resistance applied by the elastic member increases the resistance of the roller. The brush applies a reverse force when brushing the belt, brushing off the material tightly adhered to the belt, thereby realizing non-powered automatic cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 5 As shown, the utility model proposes a belt conveyor cleaning device, including a conveyor belt 1, a base plate 2, a roller 4, a scraper 7, a rotating seat 12 and a rotating shaft 18. The scraper 7 and the roller 4 are respectively arranged above the base plate 2, and the conveyor belt 1 is arranged above the roller 4. The scraper 7 is in the shape of an angle plate, and one end of the scraper 7 is provided with cutting teeth 9 distributed at equal intervals. The upper end horizontal height of the cutting teeth 9 is lower than the upper end horizontal height of the scraper 7. Slide blocks 8 are provided at the front and rear ends of the scraper 7, and a symmetrically distributed slide 6 is provided at the upper end of the base plate 2. The slider 8 is slidably installed inside the slide 6. A spring 16 is provided at one end of the scraper 7, and a support plate 14 is provided at the upper end of the base plate 2. A travel hole 15 is opened inside the support plate 14. A guide rod 17 sliding through the spring 16 and the travel hole 15 is provided at one end of the scraper 7.

[0022] Based on the implementation steps of Example 1: During the transmission process of the conveyor belt 1, the return conveyor belt 1 cuts the block-shaped adhered materials into small pieces through the scraping teeth, reducing the adhesion tightness of the block-shaped adhered materials, and scrapes off the cut materials through the scraper 7, and the obvious block materials adhering to the return conveyor belt 1 are scraped off. When the conveyor belt 1 is brushed by the brush 5, it plays a role of pre-cleaning. At the same time, when the adhered solid material is tight, the spring 16 is forced to contract, reducing the resistance to the conveyor belt 1, avoiding the problem of obvious jamming of the conveyor belt 1 affecting the transportation.

[0023] like Figure 1-Figure 5 As shown, compared with the first embodiment, the belt conveyor cleaning device proposed by the present invention further includes: the outer wall of the drum 4 is provided with brushes 5 distributed in a circular array, the upper end of the bottom plate 2 is provided with a symmetrically distributed support seat 3, the front and rear ends of the drum 4 are rotatably inserted into the support seat 3, the upper end of the bottom plate 2 is provided with a symmetrically distributed mounting seat 10, one end of the mounting seat 10 is provided with a rotating seat 12, and a rotating shaft 18 is rotatably installed inside the rotating seat 12, the outer wall of the rotating shaft 18 is sleeved with a torsion spring 21, the two ends of the torsion spring 21 are respectively connected to the rotating seat 12 and the rotating shaft 18, a stopper 19 is provided at one end of the rotating shaft 18, the outer walls of the front and rear ends of the drum 4 are sleeved with rotating plates 20 distributed in a circular array, one end of the stopper 19 is located between the rotating plates 20, a brush plate 11 is provided at the upper end of the bottom plate 2, and one end of the brush plate 11 is provided with a scraper 13 distributed in a rectangular array, and one end of the scraper 13 corresponds to the brush 5.

[0024] In this embodiment, when the return conveyor belt 1 passes through the brush 5, the friction force drives the brush 5 and the roller 4 to rotate. When the roller 4 rotates, it drives the rotating plate 20 to squeeze the block 19. The block 19 obtains elastic torsional support through the torsion spring 21, and applies a short interception resistance to the rotating plate 20, causing the roller 4 to intermittently jam. The friction force of the brush 5 on the brush material of the return conveyor belt 1 is increased, and the residual material adhering to the lower end of the conveyor belt 1 is effectively brushed off, and the material is cleaned to the lower end, which is convenient for the staff to clean.
