The invention discloses a chute system. The chute system comprises a plurality of chutes and chute connecting devices connected with the chutes. The chutes comprise bottom plates, baffle groove sidesare arranged on one sides of the bottom plates, shovel plate groove sides are arranged on the other sides of the bottom plates, and middle plates are arranged in parallel above the bottom plates. Insert block grooves are symmetrically formed in the two ends of the baffle groove sides and the shovel plate groove sides, and the insert block grooves of the adjacent chutes are connected in a butting mode and then matched with connecting blocks. L-shaped grooves are formed in the two ends of the middle plates, so that gaps corresponding to tongue plates are formed in the adjacent middle plate positions after the adjacent chutes are connected in a butting mode and is used for the insertion of the tongue plates. According to the chute system, the chute connecting devices have consistent left-right structures, machining is convenient, and the production cost is low; and during the use process, the tongue plates are overlapped in a left and right symmetrical mode, and smooth transition is achieved, the left and right working faces are not required to be considered, clamping brought when a scraping plate passes through a joint in the reverse direction is avoided, the motor load is reduced, and the cost is saved.
Description
technical field [0001] The invention relates to the field of coal mine underground transportation devices, in particular to a chute system and a chute connection device thereof. Background technique [0002] The scraper conveyor is one of the important equipments for underground comprehensive mechanical coal mining. It undertakes the task of transferring the coal and gangue mined by the shearer to the scraper transfer machine. The chute of the scraper conveyor is an important part of material transportation. The chute is the main component of the middle section of the scraper conveyor. The service life of the chute is the key factor determining the service life of the scraper conveyor. [0003] The existing scraper conveyor chute adopts dumbbell pin or eight-character ring structure. The scraper conveyor must bear the action of pushing forward and pulling the support after the coal mining machine has finished mining coal. The male head and its dumbbell are the main component...
