With the above technical solutions and referring to the drawings, it can be known that the driving portion 12 in the scraper conveying mechanism 1 controls the opening and closing of the discharge channel 14 by driving the opening and closing mechanism 3 through the transmission mechanism 2, and the specific working process and the movement trajectory are as follows:
firstly, when the opening and closing member 31 and the telescopic member 32 on the opening and closing mechanism 3 are closed, the cross section of the opening and closing member is in a V shape, so that the design aims to ensure that when materials are fed from an inlet on the discharging channel 14 to the opening and closing mechanism 3, the materials are concentrated at the bottom of the V shape under the action of gravity, when the opening and closing member 31 is rotated and opened, the bottom of the V shape is changed from a closed state to an open state, the materials can be discharged from an outlet of the discharging channel 14 along the opening of the bottom of the V shape, when the opening and closing member 31 is rotated and closed, the bottom of the V shape is closed again, and the circulation is repeated, so that the function of controlling the materials to be discharged from the discharging channel 14 is realized;
compared with the traditional mode of controlling the opening and closing of the discharging channel 14 by adopting a sliding cover type structure, when the sliding cover slides at the inlet or the opening of the discharging channel 14, although the function of opening and sealing the inlet or the opening can be realized, because the sliding cover is generally a relatively straight plate-shaped or block-shaped mechanism, materials can be directly accumulated on the surface of the sliding cover during sealing, when the sliding cover moves, the materials can inevitably be driven to move together, if the materials enter a gap between the sliding cover and the discharging channel 14, the resistance generated when the sliding cover moves is inevitably increased, and when the situation that the sliding cover is blocked directly occurs in serious cases;
compared with the traditional mode of controlling the opening and closing of the discharging channel 14 by adopting the turnover cover, the opening and closing mechanism 3 is generally arranged at the outlet of the discharging channel 14 by adopting the turnover cover, and the turnover cover is generally only one or two, so that when the turnover cover is opened, materials can be scattered in advance or towards an area far away from receiving equipment such as a transfer trolley and the like from a gap between the turnover cover and the turnover cover or a gap between the turnover cover and the discharging channel 14, and the waste of the materials and the working difficulty of later-period cleaning are caused;
the opening and closing mechanism 3 in the scheme is positioned in the discharging channel 14, when the opening and closing mechanism 3 is in opening and closing movement, the problem that materials fall in the area away from receiving equipment such as a transfer trolley and the like can not occur, meanwhile, the opening and closing mechanism 3 with the V-shaped cross section is designed, the materials can be concentrated at the bottom of the V shape under the action of gravity, when the opening and closing mechanism is opened, the materials can be discharged from the outlet of the discharging channel 14 along the opening at the bottom of the V shape, the situation that the opening and closing mechanism 3 is clamped by the materials can not occur, the mechanism has the characteristic of good stability, meanwhile, the expansion piece 32 and the opening and closing piece 31 are tightly matched, the sealing performance of the opening and closing mechanism 3 can be better, when a plurality of opening and closing pieces 31 in the opening and closing mechanism 3 rotate, the falling track of the materials from the opening and closing mechanism 3 is concentrated at the central part of the opening and closing mechanism 3, the situation that the falling track is not fluctuated when the materials are discharged can not occur, has the characteristic of good stability.
Referring to fig. 1 and 7, as an embodiment of the present application, the present application further includes a slag removing mechanism 4 located in the discharging channel 14, where the slag removing mechanism 4 includes:

When the traction force of the traction assembly 232 drives the opening and closing member 31 in the opening and closing mechanism 3 to rotate so as to open the opening and closing mechanism 3, the linkage member 412 can drive the cleaning part 41 to tightly attach to the inner wall of the discharging channel 14 at the moment, so that the materials adhered to the inner wall of the discharging channel 14 can be scraped, the materials fall along the discharging channel 14, the situation that the discharging channel 14 is blocked due to the adhesion of the materials to the discharging channel 14 is avoided, and the second return spring is in a tense state at the moment;
when the opening and closing member 31 loses the traction force of the traction assembly 232, the elastic deformation of the second return spring can drive the cleaning part 41 to move towards the direction away from the second guide member 42, and then the opening and closing member 31 is driven to rotate reversely through the linkage part 412 to close the opening and closing mechanism 3, when the driving part 12 in the scraper conveying mechanism 1 opens the opening and closing mechanism 3 through the transmission mechanism 2, the material is discharged from the discharging channel 14, the deslagging mechanism 4 is driven to move to clean the material adhered to the inner wall of the discharging channel 14, and meanwhile, the second return member 43 in the deslagging mechanism 4 can drive the opening and closing member 31 to move reversely to close the opening and closing mechanism 3, so that the device has the characteristics of tight structure matching and material blockage prevention.

when the opening and closing member 31 loses the traction force of the traction assembly 232, the elastic deformation of the second return spring drives the cleaning part 41 to move in the direction away from the second guide member 42, and then the linkage 412 drives the opening and closing member 31 to rotate reversely to close the opening and closing mechanism 3, and when the crank link assembly 22 drives the opening and closing member 31 to move again through the traction assembly 232, the opening and closing mechanism 3 is opened again, and the process is repeated in a circulating manner.
In conclusion, when the scraper conveying mechanism 1 works, the rack 2312 on the sliding component 23 can be driven by the crank connecting rod component 22 to do reciprocating linear motion, and then the gear 2322 drives the first winding member 2321 to rotate, when the first winding member 2321 winds the pulling member 2323, the opening and closing member 31 in the opening and closing mechanism 3 can be driven to rotate to open the opening and closing mechanism 3, meanwhile, the expansion piece 32 can lead the two adjacent opening and closing pieces 31 to be in a sealing state by being wound on the second winding piece 313 in the opening and closing piece 31, the opening and closing piece 31 on the opening and closing mechanism 3 and the expansion piece 32 are designed to be V-shaped in section when being closed, materials can be intensively distributed at the bottom of the opening and closing mechanism 3, the situation that the opening and closing mechanism 3 is blocked is prevented, the scraper conveyor has the advantages of good stability, prolongs the service life of the discharging device, and solves the problem that the discharging device of the existing scraper conveyor for mines is easy to block by materials and causes short service life.
