Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 5, the present invention provides a technical solution: the utility model provides a novel thrust wheel for excavator, including thrust wheel body 1, two rubber sleeves 2 of fixed surface of thrust wheel body 1, through setting up rubber sleeve 2, and the cladding of rubber sleeve 2 is outside thrust wheel body 1, thereby can play the guard action to it, avoid the problem of wearing and tearing, a plurality of recess 3 has been seted up to the surface of rubber sleeve 2, the front of recess 3 inner wall is through the back fixed connection of first spring 4 with rubber lug 5, through setting up first spring 4 and rubber lug 5, and rubber lug 5 can become thrust wheel body 1 through the elastic deformation of first spring 4 and provide the cushioning effect, reduce the extrusion that external force caused thrust wheel body 1, rubber lug 5's shape sets up to semi-circular.

The fixed plates 8 are respectively lapped on the left side surface and the right side surface of the thrust wheel body 1, four mounting blocks 7 are fixedly connected to the outer surface of the fixed plate 8, the four mounting blocks 7 are fixedly connected with the thrust wheel body 1 through bolts 6, the mounting and dismounting effects of the fixed plate 8 can be achieved through the bolts 6, so that the mounting and dismounting operations of the hairbrush 10 are facilitated, the replacement operation of the hairbrush 10 which is seriously worn in long-time use is facilitated, the practicability of the device is improved, the upper surface and the lower surface of the inner wall of the fixed plate 8 are respectively fixedly connected with the opposite surfaces of the two hairbrushes 10 through a plurality of telescopic devices 9, the hairbrush 10 is composed of a plurality of brush wires which are flexible brush wires, the shape of the hairbrush 10 is arc-shaped, and the hairbrush 10 is arranged to be arc-shaped so as to be conveniently matched with the shape of the thrust wheel body 1, thereby be favorable to the work of cleaning of brush 10, telescoping device 9 includes telescopic link 91, through setting up telescopic link 91, and telescopic link 91 can guarantee the flexible stability of second spring 92, second spring 92 has been cup jointed to telescopic link 91's surface, through setting up second spring 92, and when brush silk wearing and tearing of brush 10 shorten, second spring 92 utilizes the elasticity of self to promote brush 10 and contact with thrust wheel body 1 once more this moment, thereby the assurance that can be better carries out the purpose of clearance to thrust wheel body 1 interior axial surface, the both ends of second spring 92 and telescopic link 91 respectively with the back of fixed plate 8 inner wall and the back fixed connection of fixed plate 8, two upper and lower surfaces at thrust wheel body 1 are lapped respectively to two brushes 10.
