Description

Technical Field

[0001] This utility model relates to the field of safety technology for coal mine transportation equipment, and in particular to an adjustable and detachable rock-blocking device for the unloading chute of a transfer machine in a roadway. Background Technology

[0002] The lifting and retaining device of the tail unloading chute of the scraper conveyor in the longwall mining roadway is directly related to the safety of underground coal mining. In fully mechanized mining faces, especially steeply inclined faces, as the coal mining machine cuts coal, the scraper conveyor transports the cut coal downwards to the tail unloading chute of the longwall mining roadway. Due to the downward force, some of the coal gangue from the working face falls rapidly to the unloading chute. If the retaining device is not properly installed, it can cause injury to personnel, posing a significant safety hazard.

[0003] Existing unloading chutes typically have fixed-height baffles that cannot be adjusted, have poor adaptability, and are prone to deformation. Alternatively, they may be directly welded onto the unloading chutes, making it impossible to accommodate interchangeable installations on the left and right working faces. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where the unloading chute is usually equipped with a fixed height baffle plate, which cannot be adjusted, has poor adaptability, and is prone to deformation; or it is directly welded to the unloading chute, which cannot adapt to the interchangeable installation of the left and right working faces. Therefore, an adjustable and detachable baffle plate device for the unloading chute of a transfer machine in a roadway is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable and detachable rock-blocking device for the unloading chute of a transfer machine in a roadway, comprising an unloading chute, a fixed base and a telescopic jack, wherein the telescopic jack is mounted on the fixed base, the output end of the telescopic jack is connected to a lifting rock-blocking plate, mounting plates are provided on both sides of the unloading chute, and the fixed base is mounted on the mounting plates.

[0006] Preferably, the fixed base is welded with an ear seat, and the telescopic jack is mounted on the ear seat.

[0007] Preferably, the fixed base is provided with a slide rail, and the lifting baffle plate slides inside the slide rail.

[0008] Preferably, the mounting plate has multiple screw holes.

[0009] Preferably, the telescopic jack is movably connected with a pin.

[0010] Preferably, the telescopic jack is connected to the fixed base and the lifting baffle plate via a pin.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, the front of the fixed base is welded with lugs for the telescopic jack, which facilitates the installation of the telescopic jack and ensures the stability of the installation. A slide rail is welded on the back, allowing the lifting baffle plate to slide within the slide rail. Two rows of holes are provided at the bottom of the fixed base, which is secured with high-strength bolts and a discharge chute, facilitating the installation and removal of the fixed base. The telescopic jack connects the fixed base and the lifting baffle plate via a pin, allowing the lifting baffle plate to be adjusted freely within the jack's stroke range as the telescopic jack extends and retracts. This device enables height adjustment, adapting to different height variations. The use of high-strength materials increases overall strength and enhances resistance to the impact of coal gangue, while also allowing for interchangeable installation on the left and right working faces.
