Description

Crusher and crushing device without middle cover

Technical Field

The utility model relates to the technical field of crushing devices, in particular to a crusher without an intermediate cover and a crushing device.

Background

In order to reduce the transportation cost by reducing the transportation volume when the waste wood of the waste building is transported by a truck, or to crush the straw baled for use, a crusher for crushing the waste wood or straw is required. The crusher generally comprises a feeding system, a crushing system and a discharging system, wherein the crushing system comprises a feeding part and a crushing part, and the feeding part relatively fixes and extrudes materials and then crushes the materials by using crushing rollers.

The existing crusher is generally characterized in that a movable jaw body is hinged on a box body at the rear part of a crushing cutter roller, the hinged point is positioned at the upper part of the box body, see fig. 5 and 6, or a crusher disclosed in CN201210115513.8, the arrangement mode is that a gap at the side part is generated between the movable jaw body and the box body, and a cover is arranged in the box body for sealing, so that the crushing cutter roller is covered. However, due to the existence of the cover, the crushing space in the box body is reduced, the crushing of materials is limited, and the cover is opened after the jaw body is opened and the jaw body is opened during maintenance, so that the maintenance is inconvenient.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides a crusher without an intermediate cover and a crushing device, and aims to solve the problems that the crushing space is small and the maintenance is inconvenient because an intermediate cover needs to be arranged at the upper part of the rear part of a box body hinged by a movable jaw at present.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a breaker of cover in middle of no, the power distribution box comprises a box body, move the jaw body and telescoping cylinder, it is located the front portion of box to move the jaw body, it is first pin joint with the box articulated and should articulated department to move the jaw body, it installs the feed roller on the jaw body to move, be provided with the crushing roller in the box, it is located the place ahead of crushing roller to go up the feed roller, be provided with flip on the box, flip is articulated and should articulated department is the second pin joint with the box, the one end of telescoping cylinder with move jaw body coupling and the flexible of telescoping cylinder can drive the jaw body and rotate around first pin joint, the other end of telescoping cylinder is connected with flip and the flexible of telescoping cylinder can drive flip and rotate around the second pin joint. In the scheme, the movable jaw body can rotate around the first hinge point through the stretching of the telescopic cylinder so as to drive the upper feeding roller to rotate, the telescopic cylinder drives the flip cover to turn over during later maintenance so as to operate the structure in the box body, the crushing roller can be covered from the upper part without arranging an intermediate cover, and in addition, the crushing space can be larger without changing the overall structure of the crusher, so that the maintenance is convenient; one telescopic cylinder realizes two actions, has a linkage structure, and is convenient and quick. The telescopic cylinder in the scheme is preferably an oil cylinder, provides power and plays a buffering role in rotation.

Further, the upper feeding roller has only one. On the basis of the arrangement, the two upper feeding rollers are replaced by one upper feeding roller, so that the diameter of the upper feeding roller becomes larger, the weight of the upper feeding roller is heavier, and the upper feeding roller can achieve a more stable feeding effect due to the fact that the upper feeding roller needs to be dependent on the weight of the upper feeding roller during feeding.

Furthermore, a connecting piece is arranged between the turnover cover and the box body. Specifically, the connecting piece is the bolt, passes through bolted connection between flip and the box, because flip is lighter, so normally during operation at ordinary times through the bolt with flip and box be connected, make telescopic cylinder's flexible can not drive flip and rotate, but only make movable jaw body rotate. When parts such as the crushing roller and the like in the box body are maintained, the telescopic cylinder can drive the turnover cover to rotate by unscrewing the bolt, and the movable jaw body and the upper feeding roller cannot rotate due to the fact that the movable jaw body and the upper feeding roller are heavier. In other schemes, the connecting piece can also be a buckle structure and the like.

Furthermore, a piston rod of the telescopic cylinder is hinged with the movable jaw body, and the hinged position is located in front of or above the first hinged point. So that the telescopic cylinder can drive the movable jaw body to rotate more smoothly.

Furthermore, the cylinder body of the telescopic cylinder is hinged with the turnover cover, so that the telescopic cylinder can drive the turnover cover to rotate more smoothly. The turnover cover is positioned at the rear part of the box body and is also positioned at the rear part of the crushing roller.

Further, the first hinge point and the second hinge point are both located above the rotation center of the crushing roller.

Furthermore, the upper part of the box body is of an openable cover body structure, and the movable jaw body and the turnover cover are both arranged on the upper part of the box body. The upper part of the box body is provided with a cover body structure which can be opened, the opening mode is preferably turned, the cover body structure is turned upwards through force application to enable the cover body structure to rotate around the rear rotating shaft, a large upper space is formed after the cover body structure is opened, and the crushing roller is installed and replaced.

In addition, the utility model also provides a crushing device which comprises a feeding device and the crusher, wherein the crusher is arranged behind the feeding device. Realize the integration of feeding and crushing.

Furthermore, the feeding device comprises a chain plate conveyor, the upper feeding roller is pressed on the upper part of the chain plate conveyor, and the upper feeding roller is positioned in front of a discharge opening of the chain plate conveyor.

According to the technical scheme, the utility model has the following advantages:

the scheme provides a crusher without an intermediate cover and a crushing device, the movable jaw body can rotate around a first hinge point through the stretching of a telescopic cylinder so as to drive an upper feeding roller to rotate, the telescopic cylinder drives a flip to turn over during later maintenance so as to operate a structure in a box body, the crushing roller can be covered from the upper part without arranging the intermediate cover, and in addition, the crushing space can be larger without changing the overall structure of the crusher, and the maintenance is convenient; one telescopic cylinder realizes two actions, has a linkage structure, and is convenient and quick. Through setting up one and going up the feed roller and replacing two once and go up the feed roller for go up the diameter that feed roller becomes bigger, weight is heavier, because need rely on the weight of feed roller during the feed, should go up the feed roller and can reach more stable feed effect.
