The purpose of this utility model addresses the above problem, and provide in a kind of stuck situation and make belt pulley idle running by the fracture of rapid wear pin, and power shaft stops operating, thus protection reductor and the reductor of mixing arm and the protective device of mixing arm.
The protective device of reductor of the present utility model and mixing arm, comprise motor, V belt, driving protection device, reductor and rabbling mechanism, motor is connected with V belt one end, the other end of V belt is connected with driving protection device, one side of driving protection device is connected with reductor, and reductor is also connected with rabbling mechanism; Rabbling mechanism comprises travelling gear, mixing drum and mixing arm, and the shaft submerging in mixing drum is installed on travelling gear, and at least one mixing arm is arranged on shaft, and travelling gear is connected with reductor; Driving protection device comprises belt wheel chuck, reductor discrepancy axle, belt pulley and pressing plate, belt wheel chuck is connected with reductor power shaft, and reductor power shaft is connected with reductor, and belt pulley is connected with belt wheel chuck, pressing plate is pressed on belt wheel chuck, and belt pulley is connected with V belt; Between belt pulley and belt wheel chuck, be connected with at least one connecting pin, connecting pin intermediate radial is provided with groove.
Described belt pulley links together by the chuck on two bearings and belt wheel chuck.
Between described two bearings, adopt hole circlip to separate.
Described pressing plate is pressed on belt wheel chuck by bolt.
Described pressing plate is pressed on belt wheel chuck by hex bolts.
Described belt wheel chuck is connected with reductor power shaft by key.
On described belt pulley, be also provided with write off hole.
In sum, the protective device of reductor provided by the utility model and mixing arm has when stuck, and the fracture of rapid wear pin makes belt pulley idle running, and reductor power shaft stops the rotation, thus the advantage of protection reductor and mixing arm.
Brief description of the drawings
Fig. 1 is the protective device structure chart of reductor and mixing arm.
Wherein, 1, mixing arm; 2, mixing drum; 3, travelling gear; 4, reductor; 5, motor; 6, V belt; 7, reductor power shaft; 8, key; 9, belt wheel chuck; 10, bearing; 11, connecting pin; 12, belt pulley; 13, pressing plate; 14, circlip for hole; 15, write off hole; 16, hex bolts.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
-as shown in Figure 1, the protective device of reductor of the present utility model and mixing arm, comprise motor 5, V belt 6, driving protection device, reductor 4 and rabbling mechanism, motor 5 is connected with V belt 6 one end, the other end of V belt 6 is connected with driving protection device, one side of driving protection device is connected with reductor 4, and reductor is also connected with rabbling mechanism; Rabbling mechanism comprises travelling gear 3, mixing drum 2 and mixing arm 1, and the shaft submerging in mixing drum 2 is installed on travelling gear 3, and at least one mixing arm 1 is arranged on shaft, and travelling gear 3 is connected with reductor 4; Driving protection device comprises belt wheel chuck 9, reductor discrepancy axle 7, belt pulley 12 and pressing plate 13, belt wheel chuck 9 is connected with reductor power shaft 7 by key 8, reductor power shaft 7 is connected with reductor 4, belt pulley 12 is connected with belt wheel chuck 9, pressing plate 13 is pressed on belt wheel chuck 9 by hex bolts 16, and belt pulley 12 is connected with V belt 6; Belt pulley 12 links together by two bearings 10 and the chuck on belt wheel chuck 9, between two bearings 10, adopt hole circlip 14 to separate, between belt pulley 12 and belt wheel chuck 9, be connected with at least one connecting pin 11, connecting pin 11 intermediate radial are provided with groove, on belt pulley 12, be also provided with write off hole 15, facilitate the plug of connecting pin 11.
When mixing arm 1 occurs when stuck, motor 5 and the huge increasing of belt pulley 12 moment moment of torsion, the power that acts on connecting pin 11 exceedes the holding capacity of its section and is cut off, the i.e. idle running on belt wheel chuck 9 of belt pulley 12, reductor power shaft 7 stops operating, reductor 4 and mixing arm 1 also stop operating, thereby reach protection reductor 4 and mixing arm 1 and avoid alleviating its damage, then close motor 5, system is quit work, remove after the stuck problem of mixing arm 1 in solution, reappose a new connecting pin 11, then open motor 5, motor 5 drive systems are normally worked.
