Embodiment 1

[0025] refer to Figure 1~3 , in an embodiment of the present invention, a gangue crushing and screening device for mine production includes a processing chamber 1, the upper middle of the processing chamber 1 is connected with a first motor 4 through a connecting piece, and the left and right sides of the first motor 4 are installed There is a feeding port 5, which can facilitate the equipment to adjust gangue. The upper side of the feeding port 5 is connected with a sealing plate through a hinge, which can effectively ensure the sealing of the equipment. The lower side of the first motor 4 is connected with a crushing shaft through a coupling. 6. The left and right ends of the lower side of the crushing shaft 6 are equipped with crushing blades 7 through the installation sleeve, and the crushing shaft 6 and the crushing blade 7 are driven by the first motor 4 to rotate and crush, so that gangue can be effectively crushed, which can To facilitate the crushing process of the e...

Embodiment 2

[0029] The difference from Embodiment 1 is: the lower ends of the left and right sides of the storage chamber 1 are fixedly installed with a support plate 2, and the lower side of the support plate 2 is fixedly installed with a bottom plate 3, which is fixedly connected with the processing chamber 1 through the support plate 2, This can effectively support the equipment, and the base plate 3 fixedly installed at the bottom can ensure the overall stability of the equipment.

Abstract

The invention relates to the field of mineral products, in particular to a gangue crushing and screening device for mine production. The gangue crushing and screening device comprises a machining cavity, the middle of the upper side of the machining cavity is connected with a first motor through a connecting piece, and the lower side of the first motor is connected with a crushing shaft through acoupler, the left end and the right end of the lower side of the crushing shaft are provided with crushing blades through installation sleeves, the outer side of the crushing blades is provided with ascreening cylinder, and the lower side of the screening cylinder is provided with a rotating plate, the lower side of the rotating plate is provided with a second flow guide groove, and the lower side of the second flow guide groove is provided with a screening hopper, discharging pipes are welded to the middle of the lower side of the screening hopper, outer gears are welded on the outer side ofthe discharging pipes, and connecting gears are meshed on the left side and the right side of the outer gears, connecting shafts are arranged in the connecting gears, and a discharging port is formedin the machining cavity located on the lower side of the discharging pipes, a discharging cavity is formed in the lower side of the discharging port, and a second motor is arranged on the lower sideof the discharging cavity through a mounting piece. According to the device, the crushed gangue can be effectively screened and separated, so that the waste of coal resources can be effectively reduced.

Description

technical field [0001] The invention relates to the field of mineral products, in particular to a gangue crushing and screening device for mine production. Background technique [0002] Coal is a combustible black or brown-black sedimentary rock that usually occurs in rock formations or veins called coal beds or seams. Because of later exposure to elevated temperatures and pressures, harder forms of coal can be considered metamorphic rocks, such as anthracite. Coal is mainly composed of carbon, together with varying amounts of other elements, mainly hydrogen, sulfur, oxygen and nitrogen. [0003] Gangue is the stone contained in the coal seam, which contains a small amount of combustibles and is not easy to burn. Commonly known as "gangster". Crushed stone extracted from underground or mixed into ore during the mining process. The thin rock layer in the middle of the coal seam is called "Jia Shi". The gangue pile on the ground of the mine is called "the gangue hill". S...
