Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a coal gangue conveying device and belongs to the technical field of coal mine sorting equipment. BACKGROUND
[0002] The raw coal mined underground contains coal gangue, which needs to be sorted out from the raw coal to improve the quality of the raw coal.
[0003] A mine currently uses a mechanical coal sorting device driven by a motor and a connecting rod mechanism to reciprocate to sort raw coal and coal gangue, which has the following technical problems in the prior art: inconvenient operation and poor reliability. INVENTION CONTENTS
[0004] The utility model solves the technical problems in the prior art by providing a coal gangue conveying device.
[0005] The utility model takes the technical scheme as follows: a coal gangue conveying device includes a main conveying belt arranged in the horizontal direction, an inclined transfer conveying belt arranged below the main conveying belt, a coal sorting device arranged above the main conveying belt, and a connecting rod arranged on the front side of the coal sorting device above the main conveying belt.
[0006] Preferably, the driving mechanism is a pneumatic cylinder.
[0007] Preferably, the lower end of the connecting rod is arranged as a plate-shaped structure arranged in the vertical direction and perpendicular to the main conveying belt.
[0008] Preferably, the pneumatic cylinder is electrically connected to the controller of the coal sorting device. When the coal sorting device detects that the material on the main conveying belt is coal gangue, the controller of the coal sorting device controls the pneumatic cylinder to extend and drive the connecting rod to move downward to contact the main conveying belt, and the coal gangue falls from the side of the main conveying belt to the transfer conveying belt. When the coal sorting device detects that the material on the main conveying belt is raw coal, the controller of the coal sorting device controls the pneumatic cylinder to retract and drive the connecting rod to move upward above the main conveying belt, and the raw coal remains on the main conveying belt.
[0009] The utility model has the advantages that compared with the prior art, the utility model drives the connecting rod to move up and down by the extension and retraction of the pneumatic cylinder, thereby achieving the conveying function of raw coal and gangue, improving the quality of raw coal, reducing the ash content of raw coal, and being easier to operate and more reliable than the existing mechanical coal sorting device. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 is the overall structure of the utility model.
[0011] The reference numerals in the accompanying drawings include: 1. Main conveyor belt; 2. Transfer conveyor belt; 3. Coal separating device; 4. Connecting rod; 5. Cylinder. Detailed Implementation
[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0013] Example 1:
[0014] A coal gangue separation and transportation device, such as Figure 1 As shown, the system includes a main conveyor belt 1 arranged horizontally, with the transmission direction of the main conveyor belt 1 being clockwise. Below the main conveyor belt 1, a transfer conveyor belt 2 is arranged inclined to the lower left. Above the main conveyor belt 1, a coal separating device 3 is arranged, which is a coal gangue sorting device. The coal separating device 3 is an existing device. Above the main conveyor belt 1, in front of the coal separating device 3, a connecting rod 4 is arranged. The lower end of the connecting rod 4 is a plate-shaped structure arranged vertically and perpendicular to the main conveyor belt 1. The width of the lower end of the connecting rod 4 in the front-back direction is greater than the width of the main conveyor belt 1. A cylinder 5 with its axis arranged vertically is installed on the frame. The telescopic arm of the cylinder 5 is arranged vertically downward. The connecting rod 4 is fixed to the lower end of the telescopic arm of the cylinder 5. The telescopic movement of the cylinder 5 can drive the connecting rod 4 to move up and down.
[0015] In this embodiment, cylinder 5 is electrically connected to the controller of coal separating device 3. When coal separating device 3 detects that the material on the main conveyor belt 1 is coal gangue, the controller of coal separating device 3 controls cylinder 5 to extend and drive connecting rod 4 to move downwards until it contacts the main conveyor belt 1, and the coal gangue falls from the side of the main conveyor belt 1 onto the transfer conveyor belt 2. When coal separating device 3 detects that the material on the main conveyor belt 1 is raw coal, the controller of coal separating device 3 controls cylinder 5 to retract and drive connecting rod 4 to move upwards above the main conveyor belt 1, and the raw coal remains on the main conveyor belt 1, thereby realizing the separation and transportation of raw coal and coal gangue.
[0016] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
