Detailed Description
Referring to fig. 1 to 6, a protection device for a worm gear reducer is shown, the protection device adopts a protection box 1, a vent 101 is arranged on the side wall of the protection box 1, a filter screen 2 is arranged at the vent 101, a fixed rack 11 is horizontally arranged at the position below the vent 101 of the protection box 1, and a driving gear 5 which is meshed with the fixed rack 11 and can horizontally move is arranged above the fixed rack 11; the driving gear 5 is coaxially provided with a driven gear 7; the pitch circle diameter of the driven gear 7 is larger than that of the driving gear 5; a movable rack 12 capable of horizontally moving is arranged above the driven gear 7; a cleaning component 14 for cleaning the filter screen 2 is arranged above the movable rack 12.
The protection device also comprises a second chute 9; the second chute 9 is arranged below the ventilation opening 101 of the protective box 1, and a sliding block 10 capable of horizontally moving along the second chute 9 is arranged in the second chute 9; the slide 10 is connected with the movable rack 12 through a connecting rod 13.
The protection device also comprises a first chute 8 and a rotating shaft 6; the opening of the first chute 8 is opposite to the opening of the second chute 9, and the first chute 8 is arranged on the second chute 9; a moving block 3 capable of moving along the first chute 8 is arranged in the first chute 8, and a fixed rack 11 is arranged below the first chute 8; one end of a rotating shaft 6 is connected with the centers of a driving gear 5 and a driven gear 7 in a penetrating way, and the other end of the rotating shaft is connected with the moving block 3 in a rotating way; the driven gear 7 is abutted against the end face of the second chute 9.
