[0005] The technical problem to be solved by the utility model is to provide a scraper conveyor transmission device frame, which prevents damage to important mechanical structures caused by falling materials by reasonably arranging the head frame and its internal structure and setting a protective mechanism, facilitates replacement and maintenance, simplifies the maintenance process, and prolongs the service life of the equipment.

[0006] The utility model provides a scraper transmission device frame, comprising a head frame, a head wheel shaft group and a protection mechanism, wherein:

[0007] The head frame includes a base, with side baffles provided on both sides of the base, and a front baffle provided at one end of the base;

[0008] The head wheel shaft assembly includes a group of bearing seats arranged on the outside of the side baffle, the head spindle passes through the side baffle and is arranged on the bearing seats, and a group of sprockets are arranged on the head spindle, and the sprockets are arranged on the inside of the side baffle;

[0009] The protection mechanism includes a group of support beams arranged between the side baffles, the two ends of the support beams are respectively installed on the inner side of the side baffles, a group of transition plates are arranged vertically on the upper side of the support beams, the other end of the transition plate is arranged above the main shaft of the machine head and a gap is left, and a sprocket protective cover is provided on the inner side of the upper part of the side baffle.

[0010] Preferably, the transition plate comprises a horizontal section and an inclined section, the horizontal section is mounted on the support beam, and the inclined section is located above the main shaft.

[0011] Preferably, an upper cover plate is connected between the tops of the two side baffles, the upper cover plate is in an inverted "V" shape, and a material drop opening is provided in the middle thereof.

[0012] Preferably, a plurality of ribs are provided on the lower side of the sprocket guard.

[0013] Preferably, an anti-coal plate is obliquely arranged on the inner side of the front baffle, and a buffer spring is provided between the anti-coal plate and the front baffle.

[0014] Working principle of the utility model: The transmission device frame of the scraper conveyor of the utility model is mainly used for the special working condition of vertical material falling above the head of the scraper conveyor. Two support beams with bevels are used in the frame of the head of the scraper conveyor, and the left and right transition plates are assembled on the upper part of the support beams. The front ends of the left and right transition plates are obliquely placed on the upper end of the main shaft and leave appropriate gaps, which simplifies the complex structure and facilitates later replacement and maintenance. In addition, in order to prevent the material from getting stuck in the sprocket socket during the operation of the equipment, sprocket protection devices are designed on the side baffles on the left and right sides, and supported by ribs. An anti-coal plate is designed on the front baffle to prevent the material from being piled up in the transmission device frame. A spring is set between the anti-coal plate and the front baffle as a buffer to reduce hard mechanical impact. In addition, an upper cover plate with a 15° inclination is added above the transmission device frame as a dust cover to prevent dust from flying.

[0015] Beneficial effects of the utility model: the scraper conveyor transmission device frame of the utility model reasonably arranges the head frame and its internal structure and sets a protective mechanism to prevent damage to important mechanical structures caused by falling materials, facilitates replacement and maintenance, simplifies the maintenance process, and prolongs the service life of the equipment.
