Abstract
The invention provides a double-roll crusher thrust adjustment device which comprises a rack, two crushing rolls, a sliding bearing pedestal, a hydraulic cylinder and a cylinder body bracket, wherein the two crushing rolls are horizontally arranged on the rack; one of the crushing rolls is a movable roll which is supported on the rack through the sliding bearing pedestal; a pressure relay is arranged on the hydraulic cylinder; the hydraulic cylinder is fixedly arranged on the rack through the cylinder body bracket; a piston rod of the hydraulic cylinder is fixedly connected with the sliding bearing pedestal; and the axial line of the piston rod is vertical to the axial lines of the crushing rolls. The double-roll crusher thrust adjustment device is simple in structure and capable of protecting double-roll crushers from damage.
Description
Technical field
The present invention relates to a kind of double-roll crusher thrust-adjusting gear.
Background technology
Existing double-roll crusher, when needs were regulated thrust, manually rotation hand wheel drove screw rod rotation propelling or retreats, and made plain bearing housing drive breaker roll and moved forward and backward.This adjustment mode, after adjustment was accomplished, breaker roll can not move again, if there is hard thing to get into, will destroys the roll surface of breaker roll, even break the travelling gear of disintegrating machine, made entire equipment shut down.
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 present invention provides, the double-roll crusher thrust-adjusting gear that can protect double-roll crusher not to be damaged.
The technical scheme that the present invention adopts is: comprise frame, two breaker rolls, plain bearing housing, hydraulic cylinder and cylinder racks; Said two breaker roll levels are installed on the frame, and one of them breaker roll is an action roller, and action roller is supported on the frame through plain bearing housing; Said hydraulic cylinder is provided with pressure switch; Hydraulic cylinder is packed on the frame through cylinder rack, and the piston rod and the plain bearing housing of hydraulic cylinder are affixed, and the axis normal of piston rod is in the axis of breaker roll.
In the above-mentioned double-roll crusher thrust-adjusting gear, be fixed with spring base on the said plain bearing housing, and be connected with thrust adjustment seat through spring, the piston rod of said hydraulic cylinder and thrust adjustment seat are affixed, the axis of spring and piston rod line parallel.
The invention has the beneficial effects as follows: the present invention is simple in structure; And it comprises hydraulic cylinder, and when foreign matter got into breaker roll, the cylinder pressure relay worked; 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 invention makes the breaker roll breaking ores have vibrating function, can make the ore particles interior tissue produce internal injury, can shorten the grinding cycle significantly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1; The present invention includes frame 1, two breaker rolls 2, plain bearing housing 3, thrust adjustment seat 6, hydraulic cylinder 7 and cylinder racks 8; Said two breaker roll 2 levels are installed on the frame 1, and one of them breaker roll 2 is an action roller 21, and action roller 21 is supported on the frame 1 through 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 said plain bearing housing 3, spring base 4 is connected with thrust adjustment seat 6 through spring 5, and the axis normal of spring 5 is in the axis of breaker roll 2; Said hydraulic cylinder 7 is provided with pressure switch; Hydraulic cylinder 7 is packed on the frame 1 through cylinder rack 8, and the piston rod 71 of hydraulic cylinder 7 is affixed with thrust adjustment seat 6, the parallel axes of the axis of piston rod 71 and spring 5; Said thrust adjustment seat supports is on frame 1, and frame 1 moves horizontally relatively.
