For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] Referring to the attached Figures 1-3 , a disassembly-free roller protective cover applicable to a belt conveyor, comprising:

[0029] The inner protective cover 1, both ends of which are located on the inner guide rail 3;

[0030] The outer protective cover 2, both ends of which are located on the outer guide rail 3, having the same structure as the inner protective cover 1, including 2 sliding bases 4 and an arc-shaped cover plate 5 connecting the 2 sliding bases 4; at both ends of the sliding base 4, 1 pulley 6 is provided respectively, and a bolt hole 7 is opened in the middle thereof;

[0031] The bolt 8 is inserted into the bolt hole 7 at the corresponding position and is threadedly engaged and locked with the positioning hole opened on the guide rail 3.

[0032] In this embodiment, the inner and outer guide rails 3 are arranged in parallel on both sides of the belt conveyor. The sliding base 4 is made of L-shaped angle steel. Both ends of the cover plate 5 are welded to the side plates of the sliding base 4 at the corresponding positions. Two symmetrical movable grooves 9 are provided on the side plates of the sliding base 4; one end of the rotating shaft of the pulley 6 is located in the movable groove 9, and a certain movable space is reserved in the movable groove 9 to allow the rotating shaft of the pulley 6 to move up and down a short distance, which is convenient for adjustment and disassembly. Two symmetrical avoidance grooves 10 are provided on the bottom plate of the sliding base 4; the pulley 6 passes through the avoidance groove 10 and contacts the guide rail 3 at the corresponding position, avoiding direct contact between the sliding base 4 and the guide rail 3, which is beneficial to reducing the frictional resistance when moving the protective cover.

[0033] It should be noted that the bolt pin 8 is a semi-threaded bolt, and its bottom is threaded to cooperate with the positioning hole on the guide rail 3 for locking. The middle area is threaded, which can avoid serious wear on the bolt pin hole 7. A pull ring 11 is provided at the top of the bolt pin 8 to facilitate tightening or pulling out the bolt pin 8.

[0034] In addition, a anti-disengagement plate 12 is provided on the guide rail 3. The anti-disengagement plate 12 can limit the pulley 6 and can, to a certain extent, prevent the pulley 6 from disengaging from the guide rail 3 during movement. The cover plate 5 has a certain elasticity. When it is necessary to remove the protective cover, the cover plate 5 can also be squeezed inward, and by using the elastic deformation of the cover plate 5, the limiting effect of the anti-disengagement plate 12 on the pulley 6 can be released, which is convenient and efficient.

[0035] During actual use, the inner protective covers 1 and the outer protective covers 2 are arranged at intervals and are respectively locked with the positioning holes on the corresponding guide rails 3 through the bolt pins 8, which can play a role in dust and rain prevention during the material transportation process. When it is necessary to overhaul the belt conveyor, only need to loosen and pull out each bolt pin 8, move each protective cover to expose the belt; after the overhaul is completed, move each protective cover along the guide rail 3 to slide back to the original position and lock it again.

[0036] The detachable roller protective cover for the belt conveyor of the present utility model can effectively suppress dust and rain and improve safety by arranging the inner protective cover 1 and the outer protective cover 2 above the belt conveyor; at the same time, it is not necessary to remove the protective cover during the inspection and maintenance operations of the belt conveyor, which is beneficial to improving work efficiency, is very practical, and has good market application prospects.
