Description

A shovel conveyor

technical field

The invention relates to the technical field of material grabbing and conveying, in particular to a shovel conveyor.

Background technique

In the material yard, manual shovel loading is inefficient. Therefore, the use of construction machinery similar to loaders can efficiently shovel or load vehicles; however, in situations where space is limited like mine roadways, small and efficient scrapers are required. For example, rotating the bucket can shovel the material, and the belt conveyor can lift and transport the material to a suitable position directly into the material truck. The two must be properly combined to achieve efficient work. However, there is no good way to complete the connection between the rotating bucket and the belt conveyor without leakage of materials. Therefore, there is always a lot of material leakage between the rotating bucket and the belt conveyor, which hinders the normal operation of the system. Constant downtime for cleaning greatly reduces efficiency. The problem is that if enough rotation space is left for the rotating bucket, it will inevitably lead to a space for spreading material between it and the belt conveyor. If the two are too close, the rotation of the bucket will be affected. If the two form a large position and height difference. , In theory, interference can be avoided, but the large height difference of the material will cause a lot of dust and cause a huge impact on the belt. In many occasions, the space is not allowed, which is a more fundamental problem.

The working process of the present invention is as follows: move the conveyor of the bucket 2-2 to the front of the material pile as a whole, drop the bucket 2-2 through the bucket lifting and lowering hydraulic cylinder 12 without mopping the ground, start the transmission belt and then start the rotary shovel Bucket 2, the material will be scooped up by the bucket 2-2. When the material is brought above the front end of the conveyor belt by the bucket 2-2, the material will start to drop. At this time, the material chute 7 is located below the bucket 2-2. At this time, the material will quickly fall into the material chute 7 and be guided to the transmission belt, and as the rotating bucket 2 continues to rotate, the pressure roller 8 on it acts on the curved boom 5, and synchronously makes the material chute 7 backward. Move, before the rotating bucket 2 reaches this position, the material chute 7 has moved out of the rotation radius of the bucket 2-2, successfully evaded, and then the material chute 7 resumes before the next bucket 2-2 is dropped. To the material receiving position, when there is a return spring 9, it can ensure a better return of the material chute 7. In this way, when each bucket 2-2 passes through, the material chute 7 moves back and forth once, which successfully ensures the continuous conveyance of the shovel.

For the self-propelled shovel conveyor, the whole machine can move forward in time as the material is dug in, and the work is more coherent;

When it is found that there are large pieces in the material pile, the crushing head can also be used to smash it;

In the field work, only the front and rear movement can not meet the requirements, so the machine adopts a left and right moving mechanism. When it needs to move left and right, the whole machine is lifted by the lifting cylinder installed above the vertical arm, and only supported by the left and right wheels. The wheels have independent drive motors that can move left and right synchronously.

The above functions are especially effective for material transfer operations in mine tunnels. It is easy to move forward and left and right, and the material is taken continuously without considering the leakage between the bucket and the conveyor belt. to work efficiently.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within the range.
