Description

Technical Field

[0001] The invention relates to the technical field of material grabbing and conveying, and in particular to a shoveling conveyor. Background Art

[0002] When taking materials from the material yard, manual shoveling is inefficient. Therefore, engineering machinery such as loaders can be used for efficient shoveling or loading; but in places with limited space such as mine tunnels, small and efficient shoveling machinery is needed. For example, the rotating bucket can shovel the material, and the belt conveyor can lift the material and transport it to the appropriate position directly into the material truck. The two must be reasonably combined to achieve efficient work. However, there is no good way to complete the connection between the rotating bucket and the belt conveyor without material leakage. 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. Continuous shutdown for cleaning greatly reduces efficiency. The problem is that if enough rotation space is left for the rotating bucket, it will inevitably leave material spilling space between it and the belt conveyor. If the two are too close, it will affect the rotation of the bucket. If a large height difference is formed between the two, interference can be avoided in theory, but the large height difference of the material falling will not only cause a lot of dust and a huge impact on the belt, but in many occasions, the space is not allowed, which is a more fundamental problem. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a shoveling material conveyor which has a compact structure, can ensure the continuous operation of the shovel bucket and can effectively avoid leakage.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] A shovel conveyor comprises a frame, a rotating bucket and a belt conveyor, wherein the belt conveyor is mounted on the frame, and the rotating bucket is mounted on the front end of the frame through a pair of support arms; the front end of the belt conveyor is located at the rear and lower part of the rotating bucket, and the rear end is raised; the rotating bucket comprises a roller and a plurality of buckets arranged on the roller;

[0006] A material chute is provided at the front end of the rotating bucket and the belt conveyor. The material chute can move forward and backward synchronously with the rotation of the rotating bucket. When the bucket is dropping materials, the material chute moves forward to receive the materials. When the bucket continues to rotate downward after dropping the materials, the material chute moves backward to avoid the materials.

[0007] The beneficial effects of the present invention are: the material chute that can swing back and forth ensures that the material dropped from the rotating bucket does not leak, and can swing synchronously with the rotation of the rotating bucket, leaving space for the rotating bucket to rotate, which greatly improves the system's working continuity and working efficiency.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, it also includes a curved boom, side plates are provided on both sides of the drum, pins are provided on the side plates, one end of the curved boom is hinged to the side plate through the pin, and the other end is hinged to the front of the material chute; a pressure wheel is also provided on the outer side of the bucket, and the pressure wheel is used to drive the curved boom and drive the material chute to swing.

[0010] The beneficial effect of adopting the above further scheme is that, through the cooperation of the pressure wheel and the bent boom, it can be ensured that the material chute automatically avoids when the bucket falls, ensuring stable operation of the equipment and the bucket will not be stuck in the material chute.

[0011] Furthermore, the side plate is provided with an upper arc groove and a lower arc groove, the inflection point axis and the lower hinge axis are respectively provided on the inflection point arm, the inflection point axis and the lower hinge axis slide in the upper arc groove and the lower arc groove respectively, and the inflection point arm is also provided with a return spring.

[0013] Furthermore, it also includes a bottom plate arranged below the material chute.

[0014] The beneficial effect of adopting the above further solution is that the bottom plate can bear the material dropped from the bucket, reduce the impact of the material on the transport belt, and increase the service life of the equipment.

[0015] Furthermore, the drum includes a fixed drum and a rotating drum, the fixed drum is provided with a drum hydraulic motor, the rotating drum is provided with a gear ring, the output gear of the drum hydraulic motor is meshed with the gear ring through an intermediate gear, and the rotating drum is rotatably or slidably connected to the fixed drum.

[0016] The beneficial effect of adopting the above further solution is that the hydraulic motor is used to provide power, thereby avoiding the situation in which the motor is frequently blocked and burned when the traditional motor drive is used.

[0017] Furthermore, it also includes a crushing mechanism, which includes a bracket, a crushing hydraulic cylinder and a crushing head. The bracket is fixed on the drum or the frame, the hydraulic cylinder is used to drive the crushing head to move, and a camera is also provided above the rotating bucket.

[0052] Fig.11 This is a schematic diagram of the hydraulic system principle of the present invention. The hydraulic station 20 provides hydraulic power for all hydraulic cylinders and hydraulic motors in the entire system. Note that this figure is a schematic diagram, and there may be multiple hydraulic cylinders marked with uniform symbols in actual applications. Only one is drawn in this figure as a representative;

[0053] Fig.12 This is a schematic diagram of the control system structure of the present invention, where the controller 30 is electrically connected to a battery 30-1, a first left and right travel motor 30-z1, a second left and right travel motor 30-z2, a third left and right travel motor 30-z3, a fourth left and right travel motor 30-z4, a hydraulic station motor 20-1, a bucket lifting cylinder controller 30-2, a material blocking claw cylinder controller 30-3, a crushing head cylinder controller 30-4, a lifting cylinder controller 30-5, a travel motor controller 30-6, a conveying motor controller 30-7, a roller motor controller 30-8, a camera 17, a bucket lifting switch 30-9 and a bucket dropping switch 30-10.

[0054] The working process of the present invention is: move the bucket 2-2 conveyor as a whole to the front of the material pile, and make the bucket 2-2 fall down through the bucket lifting hydraulic cylinder 12, but do not drag the ground, start the transmission belt and then start the rotating bucket 2, then the material will be shoveled by the bucket 2-2, and when the material is brought to the front end of the transmission belt by the bucket 2-2, it starts to fall, and 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 guide the transmission belt, and as the rotating bucket 2 continues to rotate, the pressure wheel 8 on it acts on the curved boom 5, and synchronously moves the material chute 7 backward. Before the rotating bucket 2 reaches this position, the material chute 7 has moved outside the rotation radius of the bucket 2-2, successfully avoiding it, and then the material chute 7 returns to the material receiving position before the next bucket 2-2 falls. When there is a return spring 9, the material chute 7 can be better returned. In this way, when each bucket 2-2 passes, the material chute 7 moves back and forth once, successfully ensuring the continuous shoveling and conveying.

[0055] For self-propelled shovel conveyors, the whole machine can move forward in time as the material is dug in, making the work more coherent;

[0056] When large pieces of material are found, the crushing head can be used to crush them;

[0057] When working on site, just moving forward and backward is not enough to meet the requirements, so this machine adopts a left and right moving mechanism. When it is necessary to move left and right, the whole machine is lifted by the lifting cylinder installed above the vertical arm, and is supported only by the left and right wheels. Each wheel has an independent drive motor and can move left and right synchronously.

[0058] The above functions are particularly effective for material transfer operations in mine tunnels. It is convenient to move forward and left and right, and the material is taken continuously without worrying about material leakage between the bucket and the conveyor belt. This allows for efficient operation.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
