Abstract
Description
Technical Field
[0001] The invention relates to a middle trough of a scraper conveyor for a mine, in particular to a composite double-insertion-plate skylight middle trough for a scraper conveyor, which is applied to the middle section of the scraper conveyor. Background Art
[0002] As a key component of the scraper conveyor, the chain is prone to wear or breakage during use, thus affecting production safety and efficiency. Its working condition directly affects the reliability and service life of the equipment. Wear and breakage can lead to mechanical failures and even safety accidents, causing economic losses and personal injuries. Therefore, regular inspection and maintenance of the chain status of the scraper conveyor is an important measure to ensure production safety and economic operation. In the middle section of the scraper conveyor, the skylight middle slot is an indispensable component for detecting the status of the lower chain. Due to the limited working space in the mine, the original single-plate skylight middle slot has a relatively small inspection surface. Therefore, it is necessary to provide a skylight middle slot with a larger inspection area and more convenient inspection and maintenance of the lower chain status. Summary of the invention
[0003] In view of the above situation, the present invention provides a composite double-plate skylight middle groove for a scraper conveyor. The composite double-plate skylight middle groove is arranged in the middle section of the scraper conveyor and is arranged at intervals with the middle groove according to a certain number. The composite double-plate skylight middle groove has a main and auxiliary plates. The front middle plate, the main plate, the auxiliary plate and the rear middle plate are limited to each other. The main plate and the baffle groove are limited by a pin assembly, which realizes the safe and stable operation of the chain and the scraper assembly on the middle plate of the skylight middle groove, increases the opening area of the middle plate, and facilitates the inspection and maintenance of the scraper chain assembly.
[0004] The technical solution adopted by the present invention is: The composite double-board skylight middle slot is composed of a chute body 1, a main board 2, a sub-board 3, and a pin assembly 4. The chute body 1 is welded by a front middle plate 11, a shovel plate slot 12, a rear middle plate 13, a connecting plate 14, a rail seat 15, a baffle slot 16, and a bottom plate 17. The front middle plate 11 and the rear middle plate 13 are designed with bosses and bosses designed on the main board 2 and the sub-board 3 to limit the position. First, the sub-board 3 is inserted into the rear middle plate 13, and then the main board 2 is inserted between the front middle plate 11 and the sub-board 3. Finally, the limit pin assembly positions the main board to complete the position fixation of all parts.
[0005] Beneficial effects of the present invention The present invention relates to a scraper conveyor composite double-insertion plate skylight middle slot, which is arranged in a certain number and at a certain interval of the middle slot and is applied to the middle section of the scraper conveyor, so as to realize the detection and maintenance functions of the state of the scraper chain assembly of the chain path under the middle section, increase the opening area of the skylight middle slot insert plate, and facilitate the operation of underground workers.

DETAILED DESCRIPTION
[0007] like Figure 1 As shown, the middle slot of the composite double-board skylight opening is composed of a chute body 1, a main board 2, an auxiliary board 3, and a limit pin assembly 4.
[0008] like Figure 2 As shown, the front middle plate 11 and the rear middle plate 13 in the chute body 1 are both provided with limiting bosses. The front middle plate limiting boss is used to support the main plug-in board 2, and the rear middle plate limiting boss is used to support the auxiliary plug-in board 3 and limit the upward displacement of the auxiliary plug-in board 3.
[0009] like Figure 3 As shown, the main plug-in board 2 is provided with two limiting bosses, which are used to position the auxiliary plug-in board 3 and overlap the front middle board respectively, and the limiting pin oblong hole is used for the final positioning of the main plug-in board 2.
[0010] like Figure 4 The auxiliary plug-in board is shown in the figure. The auxiliary plug-in board is provided with four limiting bosses and a semicircular separation recess to facilitate the separation of the auxiliary plug-in board and the rear middle plate.
[0011] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here.
