Abstract
The utility model provides a thrust adjusting device of a roller crusher. The thrust adjusting device comprises a rack, two crushing rollers, a sliding bearing seat, a hydraulic cylinder and a cylinder body support. The two crushing rollers are horizontally arranged on the rack. One crushing roller is an action roller which is arranged on the rack in a supporting mode through the sliding bearing seat. A pressure relay is arranged on the hydraulic cylinder which is fixedly arranged on the rack through the cylinder body support. A piston rod of the hydraulic cylinder is fixedly connected with the sliding bearing seat. The axis of the piston rod is perpendicular to the axis of the crushing rollers. The thrust adjusting device of the roller crusher is simple in structure and can protect the roller crusher from being damaged.
Description
Technical field
The utility model relates to a kind of double-roll crusher thrust-adjusting gear.
Background technology
Existing double-roll crusher, when needs were regulated thrust, the manual rotation handwheel drove screw rod rotation propelling or retreats, and moved forward and backward so that plain bearing housing drives breaker roll.This adjustment mode, after adjustment was finished, breaker roll can not move again, if there is hard thing to enter, will destroy the roll surface of breaker roll, even break the travelling gear of disintegrating machine, so that whole equipment downtime.
Summary of the invention
In order to solve the problems of the technologies described above, it is a kind of simple in structure that the utility model provides, the double-roll crusher thrust-adjusting gear that can protect double-roll crusher not to be damaged.
The technical solution adopted in the utility model is: comprise frame, two breaker rolls, plain bearing housing, hydraulic cylinder and cylinder racks, described two breaker roll levels are installed on the frame, one of them breaker roll is action roller, action roller is supported on the frame by plain bearing housing, described hydraulic cylinder is provided with pressure switch, hydraulic cylinder is packed on the frame by cylinder rack, and piston rod and the plain bearing housing of hydraulic cylinder are affixed, and the axis of piston rod is perpendicular to the axis of breaker roll.
In the above-mentioned double-roll crusher thrust-adjusting gear, be fixed with spring base on the described plain bearing housing, and be connected with the thrust adjusting seat by spring, the piston rod of described hydraulic cylinder and thrust adjusting seat are affixed, the axis of spring and piston rod line parallel.
The beneficial effects of the utility model are: the utility model is simple in structure, and it comprises hydraulic cylinder, when having foreign matter to enter breaker roll, the cylinder pressure relay works, the rapid rollback of the piston rod of hydraulic cylinder, foreign matter is got rid of smoothly, has protected the pressure roller roll surface injury-free, has protected the unlikely damage of whole double-roll crusher; And spring of the present utility model can make the ore particles interior tissue produce internal injury so that the breaker roll breaking ores has vibrating function, can significantly shorten the grinding cycle.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises frame 1, two breaker rolls 2, plain bearing housing 3, thrust adjusting seat 6, hydraulic cylinder 7 and cylinder racks 8, described two breaker roll 2 levels are installed on the frame 1, one of them breaker roll 2 is action roller 21, action roller 21 is supported on the frame 1 by plain bearing housing 3, action roller 21 and plain bearing housing 3 together, frame 1 moves horizontally relatively.Be fixed with spring base 4 on the described plain bearing housing 3, spring base 4 is connected with thrust adjusting seat 6 by spring 5, and the axis of spring 5 is perpendicular to the axis of breaker roll 2; Described hydraulic cylinder 7 is provided with pressure switch, hydraulic cylinder 7 is packed on the frame 1 by cylinder rack 8, and the piston rod 71 of hydraulic cylinder 7 is affixed with thrust adjusting seat 6, and the axis of piston rod 71 is parallel with the axis of spring 5, described thrust adjusting seat is supported on the frame 1, and frame 1 moves horizontally relatively.
