Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] see figure 1 with figure 2 , shows the structure of the middle trough of the scraper conveyor provided by the present invention. As shown in the figure, the middle trough of the scraper conveyor (hereinafter also referred to as the middle trough) at least includes: a blade groove side 1, a baffle groove Help 5, middle plate 3, bottom plate 4 and pin track 2.

[0022] Wherein the scraping plate groove side 1 comprises a blade plate 11 and a groove side body 13 connected together. The baffle groove side 5 is connected with the connecting ear seat 7 . The middle plate 3 is connected between the groove side 1 of the blade and the groove side 5 of the baffle plate. The bottom plate 4 is...

Abstract

The invention provides a middle groove of a scraper conveyer, the scraper conveyer and fully-mechanized coal mining equipment. The middle groove of the scraper conveyer comprises an insertion board ledge, a baffle ledge connected with a connecting support lug, a middle board, a base board, and a pin rail matched with traveling gear teeth of a coal mining machine, wherein a guiding cambered surface in sliding fit with guiding piston shoes of the coal mining machine is arranged on the baffle ledge. Due to the fact that the guiding cambered surface in sliding fit with the sliding piston shoes of the coal mining machine is arranged on the baffle ledge, the horizontal sliding range of the coal mining machine is limited, impact of substantial horizontal sliding of the coal mining machine on the pin rail of the middle groove is reduced, and the service life of the pin rail is prolonged.

Description

technical field [0001] The invention relates to mining conveying equipment, and more specifically, to a middle groove of a scraper conveyor, a scraper conveyor and fully mechanized mining equipment. Background technique [0002] Currently, coal mining operations are typically performed with fully mechanized mining equipment including face conveyors and shearers. Among them, the scraper conveyor includes a multi-section middle trough, and the middle trough generally includes a baffle groove side, a blade groove side, a middle plate, and a bottom plate, and the middle plate and the bottom plate are respectively connected between the baffle groove side and the blade groove side , forming a central trough structure. The baffle sill is equipped with a pin rail that matches the traction gear teeth (also known as the walking gear) of the coal shearer; Shovel plate, the upper surface of the shovel plate forms the shovel plate surface, and the coal shearer is provided with a suppor...
