DETAILED DESCRIPTION

[0028] The application will be further described in detail below with reference to the drawings.

[0029] Please refer to Figures 1-7 In the embodiment of the application, an emulsion explosive conveying anti-adhesion equipment comprises:

[0030] A frame body 1 is internally fixedly provided with an oil storage tank 3, and the oil outlet end of the oil storage tank 3 is connected with an oiling mechanism 4; and

[0031] A special-shaped conveying belt 2 is connected to one side of the frame body 1, and the special-shaped conveying belt 2 is composed of a horizontal part and an inclined part (this is prior art), and the upper part of the inclined part of the special-shaped conveying belt 2 is provided with the oiling mechanism 4;

[0032] In actual use, the special-shaped conveying belt 2 is started first, and the flow of lubricating oil in the oil storage tank 3 and the interlocking property of the lubricating oil and the conveying belt are controlled in the transmission process, and then the position of the oiling mechanism 4 is adjusted according to actual requirements, so that the lubricating oil is sprayed on the surface of the conveying belt, and along with the transmission of the special-shaped conveying belt 2, the lubricating oil flows downward along the inclined surface and covers the surface of the conveying belt, forming an oil film.

[0033] Please refer to Figure 2The oil storage tank 3 comprises a flow regulating valve 31 and a pneumatic stop valve 32, the flow regulating valve 31 is used for regulating the flow of lubricating oil in the oil storage tank 3, and the pneumatic stop valve 32 controls the interlocking of the lubricating oil and the profiled conveyor belt 2, that is, the lubricating oil flows out in cooperation with the movement of the conveyor belt.

[0034] Please refer to Figure 3 and Figure 7 As a preferred embodiment, a guide roller 21 is rotatably arranged above the connection between the horizontal part and the inclined part of the profiled conveyor belt 2, and a felt 22 is wound on the guide roller 21, and the guide roller 21 and the felt 22 can brush the lubricating oil on the surface of the conveyor belt again during rotation.

[0035] Please refer to Figure 4 The oiling mechanism 4 comprises:

[0036] A guide column 41 is fixedly arranged in the rack body 1, and an oiling pneumatic cylinder 42 is hingedly arranged at the upper end of the guide column 41, and a connecting plate is hingedly arranged at the output end of the oiling pneumatic cylinder 42;

[0037] An oscillating arm 43 is rotatably arranged at one end on the guide column 41, and a spraying assembly 45 is rotatably arranged at the other end of the oscillating arm 43, and the oscillating arm 43 is slidably arranged with a connecting plate;

[0038] A supporting arm 44 is rotatably arranged at the lower end on the guide column 41, and the spraying assembly 45 is rotatably arranged at the upper end of the supporting arm 44;

[0039] That is, when the oiling pneumatic cylinder 42 is retracted, the oscillating arm 43 and the supporting arm 44 rotate clockwise, and the spraying assembly 45 rises; when the oiling pneumatic cylinder 42 is extended, the oscillating arm 43 and the supporting arm 44 rotate counterclockwise, and the spraying assembly 45 descends, that is, the thickness of the oil film is indirectly controlled by controlling the height of the spraying assembly 45 at a certain rotating speed of the conveyor belt.

[0040] Please refer to Figure 5 As a preferred embodiment, the spraying assembly 45 comprises a preset frame rotatably arranged on the oscillating arm 43 and the supporting arm 44, two oil outlet pipes 451 are symmetrically arranged on the preset frame, and a first nozzle 452 and a second nozzle 453 are respectively arranged on the two oil outlet pipes 451.

[0041] As a preferred embodiment, as shown in Figure 6 The inclined part of the profiled conveyor belt 2 at the lower end of the oil outlet pipe 451 is arranged in a "V" shape, and the maximum opening angle of the "V" shape is 170°, and the opening angle of the "V" shape gradually decreases from top to bottom to the horizontal direction to be "one" type, which prevents the emulsion explosive from accumulating in the "V" type groove and is not conducive to cleaning.

[0042] It should be noted that the second nozzle 453 can spray lubricating oil to drop on the edge of the conveyor belt 3-5 CM, on the one hand to prevent the lubricating oil from flowing out of the conveyor belt, that is, the "V" type conveyor belt will shrink between the two side baffles when it is in the horizontal plane, so it is not necessary to lubricate the whole conveyor belt, on the other hand, the lubricating oil dropped by the first nozzle 452 and the second nozzle 453 moves in an arc due to the centrifugal effect of the conveyor belt during transmission, so that the first nozzle 452 can fill the area that the lubricating oil sprayed by the second nozzle 453 fails to cover.

[0043] That is, the lubricating oil is sprayed on the surface of the conveyor belt by the first nozzle 452 and the second nozzle 453, and the lubricating oil flows downward due to its own flow characteristics and cooperates with the transmission of the conveyor belt, so that the lubricating oil moves irregularly on the surface of the conveyor belt, which can better adhere to the surface layer of the conveyor belt.

[0044] Please refer to Figure 7 As a preferred embodiment, the felt 22 is convex at both ends and the middle, and the convex shape of the felt 22 is arranged corresponding to the shape of the lower end opening angle of the "V" shaped special-shaped conveyor belt 2.

[0045] It should be noted that the tail end of the special-shaped conveyor belt 2 is matched with a scraper, which can cooperate with the horizontal part of the special-shaped conveyor belt 2 to scrape off the emulsion explosive.

[0046] That is, the convex felt 22 can first contact the conveyor belt, so that the oil film thickness of the middle part of the conveyor belt is smaller than that of the two sides, that is, the smoothness of the middle part of the conveyor belt is less than that of the two sides, and the emulsion explosive will automatically gather to the middle when it is conveyed on the conveyor belt, and the surface of the conveyor belt is relatively smoother due to the action of the oil film, which is more conducive to the complete scraping of the emulsion explosive by the scraper.

[0047] In specific implementation, first start the special-shaped conveyor belt 2, open the flow regulating valve 31 to control the flow of lubricating oil during transmission, then start the pneumatic stop valve 32 to control the interlocking of the lubricating oil and the conveyor belt (the lubricating oil flows out when the belt moves), adjust the position height of the oil outlet pipe 451 through the oil laying cylinder 42, and spray the lubricating oil on the surface of the conveyor belt through the first nozzle 452 and the second nozzle 453. During the transmission of the conveyor belt, the lubricating oil flows downward along the "V" shaped slope of the special-shaped conveyor belt 2 and covers on the surface of the conveyor belt, forming an oil film, and cooperating with the rotation of the guide roller 21 and the felt 22 to brush the lubricating oil again, when the conveyor belt idles for 1-2 turns, the emulsion explosive is released to the horizontal part of the special-shaped conveyor belt 2, and the emulsion explosive automatically converges to the middle during the conveying process, and then the scraper completely scrapes off the emulsion explosive.

[0048] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
