Abstract

The present invention discloses a self-propelled bucket conveyor, which comprises a frame, a rotating bucket and a belt conveyor. It is characterized in that the belt conveyor is installed on the frame, and the rotating bucket is installed at the front end of the frame through a pair of support arms; the front end of the belt conveyor is located below and behind the rotating bucket, and the rear end is lifted. The rotating bucket comprises a drum and a plurality of buckets arranged on the drum; a material chute is arranged between the rotating bucket and the front end of the belt conveyor. The material chute can move back and forth synchronously with the rotation of the rotating bucket. When the bucket is discharging materials, the material chute moves forward to receive the materials.

This greatly improves the working continuity and working efficiency of the system.

Description

Technical Field

[0001] The present invention relates to the technical field of material grabbing and conveying, and particularly to a self-propelled bucket conveyor. Background Art

[0002] When taking materials in a stockyard, the manual shoveling efficiency is low. Therefore, construction machinery such as loaders can be used for efficient shoveling and loading; however, in a space-limited occasion such as a mine roadway, small and efficient shoveling machinery is required. For example, a rotating bucket can lift materials, and a belt conveyor can lift and convey the materials to a suitable position and directly into a material truck. The two must be reasonably combined to achieve efficient operation. However, there is no good way to complete the seamless connection of materials without spillage between the rotating bucket and the belt conveyor. Therefore, there is always a lot of material spillage between the rotating bucket and the belt conveyor, which in turn hinders the normal operation of the system. Continuous shutdown for cleaning greatly reduces the efficiency. The problem is that if enough rotating space is left for the rotating bucket, it will inevitably result in a spillage space between it and the belt conveyor. If they are too close, it will affect the rotation of the bucket. If a large height difference is formed between the two, theoretically, interference can be avoided, but in addition to causing a lot of dust and a huge impact on the belt when the materials fall from a large height difference, the more fundamental problem is that the space does not allow in many occasions; in addition, as the materials are shoveled, it is necessary to continuously push the materials in front of the bucket. In addition to increasing labor, the operation space and safety issues also need to be considered. Therefore, another important problem in improving the working efficiency of this type of shovel conveyor is to solve the overall independent front-back and left-right movement of the conveyor. Summary of the Invention

[0003] Aiming at the above deficiencies of the prior art, the present invention provides a self-propelled bucket conveyor with a compact structure, which can ensure the continuous operation of the bucket and effectively avoid spillage.

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

[0005] A self-propelled bucket conveyor includes a frame, a rotating bucket and a belt conveyor. The belt conveyor is installed on the frame, and the rotating bucket is installed at the front end of the frame through a pair of support arms; the front end of the belt conveyor is located below the rear of the rotating bucket, and the rear end is lifted. The rotating bucket includes a drum and a plurality of buckets arranged on the drum; it also includes a traveling mechanism, and the traveling mechanism is a crawler structure, and the frame is fixed on the traveling mechanism.

[0006] It also includes a left-right movement mechanism. The left-right movement mechanism includes four electric motor wheels arranged on the frame, and also includes a lifting hydraulic cylinder capable of lifting the traveling mechanism.

[0007] A material chute is provided at the front end of the rotary bucket and the belt conveyor. The material chute can move back and forth synchronously with the rotation of the rotary bucket. When the bucket is discharging materials, the material chute moves forward to receive the materials. When the bucket continues to rotate downward after discharging materials, the material chute moves backward to avoid interference.

[0008] The beneficial effects of the present invention are as follows: By using a material chute that can swing back and forth, it is ensured that the materials discharged from the rotary bucket do not spill, and it can swing synchronously with the rotation of the rotary bucket, leaving a rotating space for the rotary bucket. This greatly improves the continuity and working efficiency of the system;

[0009] It can move forward and backward, left and right autonomously, especially suitable for continuous advancement in the mine tunnel, with a high degree of automation and high operation effect.

[0010] On the basis of the above technical solutions, the present invention can be further improved as follows.

[0011] Furthermore, it further includes a bent boom. Side plates are provided on both sides of the drum. Pin shafts are provided on the side plates. One end of the bent boom is hinged to the side plate through the pin shaft, and the other end is hinged to the front part of the material chute; A pressure wheel is also provided outside the bucket, and the pressure wheel is used to drive the bent boom and drive the material chute to swing.

[0012] The beneficial effect of adopting the above further solution is that through the cooperation of the pressure wheel and the bent boom, it can be ensured that the material chute automatically avoids interference when the bucket drops, ensuring the stable operation of the equipment and preventing the bucket from being stuck by the material chute.

[0013] Furthermore, an upper arc-shaped groove and a lower arc-shaped groove are also formed on the side plate. A turning point shaft and a lower hinge shaft are respectively provided on the bent boom. The turning point shaft and the lower hinge shaft slide in the upper arc-shaped groove and the lower arc-shaped groove respectively, and a return spring is also provided on the bent boom.

[0014] The beneficial effect of adopting the above further solution is that it restricts the running track of the bent boom, ensuring the stable operation of the bent boom and preventing it from deforming inward due to excessive force and affecting the operation of the bucket.

[0015] Furthermore, it further includes a bottom plate provided below the material chute.

[0016] The beneficial effect of adopting the above further solution is that the bottom plate can bear the materials falling from the bucket, reduce the impact of the materials on the conveyor belt, and improve the service life of the equipment.

[0017] Furthermore, the drum includes a fixed drum and a rotating drum. A drum hydraulic motor is provided inside the fixed drum. A gear ring is provided on the rotating drum. The output gear of the drum hydraulic motor meshes with the gear ring through an intermediate gear, and the rotating drum is rotatably or slidably connected to the fixed drum.

[0018] The beneficial effect of adopting the above further solution is that the hydraulic motor is used to provide power, avoiding the situation that the motor is frequently burned out due to locked rotor when the traditional motor drive is adopted.

[0019] Furthermore, it further 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, and the hydraulic cylinder is used to drive the crushing head to act. A camera is also provided above the rotating bucket.

[0020] The beneficial effect of adopting the above further solution is that if there are large pieces of materials in the front, they can be crushed and cleaned in time, and with the cooperation of the camera, remote observation can be carried out to improve work efficiency.

[0021] The beneficial effect of adopting the above further solution is that it is convenient to adjust the position in a narrow mine tunnel.

[0022] Furthermore, it further includes a material retaining mechanism, which includes a material retaining arm bracket, a material retaining arm, a material retaining claw and a material retaining claw oil cylinder. The material retaining claw oil cylinder drives the material retaining claw to move left and right.

[0023] The beneficial effect of adopting the above further solution is that the scattered materials in the front can be collected, with higher work efficiency and a wider operation range. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The material chute 5 can move back and forth synchronously with the rotation of the rotary bucket 2. When the bucket is discharging materials, the material chute 5 moves forward to receive the materials.

The material blocking claw oil cylinder 16-4 drives the material blocking claw 16-3 to move left and right.

[0051] Figure 11 This is a schematic diagram of the principle of the hydraulic system of the present invention. The hydraulic station 20 provides hydraulic power for all hydraulic cylinders and hydraulic motors in the whole system. Note that this figure is a schematic diagram. There may be multiple hydraulic cylinders marked with the same symbol in actual application. Only one is drawn in this figure as a representative.

[0052] Figure 12 This is a schematic diagram of the control system structure of the present invention. The controller 30 is electrically connected to a storage battery 30-1, a first left-right traveling motor 30-z1, a second left-right traveling motor 30-z2, a third left-right traveling motor 30-z3, a fourth left-right traveling motor 30-z4, a hydraulic station motor 20-1, a bucket lifting and lowering oil cylinder controller 30-2, a material blocking claw oil cylinder controller 30-3, a crushing head oil cylinder controller 30-4, a lifting oil cylinder controller 30-5, a traveling motor controller 30-6, a conveying motor controller 30-7, a drum motor controller 30-8, a camera 17, a bucket lifting switch 30-9 and a bucket lowering switch 30-10.

[0053] The working process of the present invention is as follows: Move the bucket 2-2 conveyor as a whole to the front of the material pile. Lower the bucket 2-2 through the bucket lifting hydraulic cylinder 12, but without touching the ground. After starting the conveyor belt, start the rotating bucket 2, then the material will be shoveled up by the bucket 2-2. When the material is carried by the bucket 2-2 above the front end of the conveyor belt, it starts to fall. 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 conveyor belt. As the rotating bucket 2 continues to rotate, the pressure wheel 8 on it acts on the crank-shaped lifting arm 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 and successfully avoided it. Then the material chute 7 returns to the receiving position before the next bucket 2-2 falls. When there is a return spring 9, it can ensure better return of the material chute 7. In this way, every time the bucket 2-2 passes by, the material chute 7 reciprocates once, successfully ensuring continuous shoveling and conveying.

[0054] For the self-propelled bucket conveyor, as the material is dug in, the whole machine can move forward in time, making the work more coherent.

[0055] When large pieces are found in the material pile, a breaker head can also be used to break them up.

[0056] When working on site, simply moving forward and backward cannot meet the requirements. Therefore, this machine is equipped with a left-right moving mechanism. When left-right movement is required, the whole machine is lifted by the lifting cylinders installed above the vertical arms and supported only by the left and right wheels. Each wheel is equipped with an independent drive motor and can move left and right synchronously.

[0057] The above functions are particularly effective for the material transfer operation in mine tunnels. It is convenient to move forward and left and right, the material taking is continuous, and there is no need to consider the leakage of materials between the bucket and the conveyor belt. Thus, the operation is efficient.

[0058] The above are only the 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 principle of the present invention shall be included in the protection scope of the present invention.
