Description

Technical Field

[0001] The present application relates to the technical field of coal mining machinery, and in particular to a scraper conveyor with a coal quantity monitoring function. Background Art

[0002] Scraper conveyor is a continuous action transport machine with a flexible body as the traction mechanism. It is mainly used to traction the scraper chain to transport bulk materials in the trough. In the current coal mining face, the role of the scraper conveyor is to transport coal and coal materials.

[0003] At present, a general scraper conveyor is mainly composed of a transmission device, a trough body, a tail, etc. For example, a patent application with publication number CN107215621A discloses a scraper conveyor, in which the drive part is arranged in the middle. After the scraper chain passes around the transmission device sprocket, the transmission chain pressure roller, the loader tail chain pressure roller, and the unloader tail chain pressure roller, the chain presents an "S-shaped" winding layout at the sprocket, forming an infinitely circulating scraper chain traction mechanism.

[0004] However, during transportation, since the height of the coal pile is too large, the top part of the coal pile easily falls to the outside of the conveyor belt during transportation, thereby reducing transportation efficiency. Summary of the invention

[0005] In order to improve transportation efficiency, the present application provides a scraper conveyor with a coal quantity monitoring function.

[0006] The present application provides a scraper conveyor with a coal quantity monitoring function, which adopts the following technical solution: A scraper conveyor with a coal quantity monitoring function, comprising: A frame is rotatably connected to a plurality of rollers, the plurality of rollers are evenly arranged along the transport direction of the frame, and a conveyor belt is commonly sleeved on the plurality of rollers; A driving assembly, disposed on the frame and used to drive the conveyor belt to rotate; Monitoring components, including a gantry, a height detection unit, and a slope detection unit; A flattening assembly is arranged on the frame, the flattening assembly is located on a side of the monitoring assembly away from the input end of the frame, and is used to reduce the height of the coal pile; Wherein, the gantry is fixed on the frame, and the conveyor belt is located in the inner frame of the gantry; the height detection unit is arranged on the gantry and is used to detect the height of the coal pile; the slope detection unit is arranged on the height detection unit and is used to detect the slope of the coal pile.

[0007] By adopting the above technical solution, the driving component drives the conveyor belt to rotate, and the conveyor belt drives the coal pile to move. The height detection unit and the slope detection unit can monitor the height and slope of the coal pile in real time. When an abnormal situation is found, such as the coal pile is too high or the slope is too large, the flattening component lowers the height of the coal pile to prevent the coal pile from collapsing or sliding, thereby improving the overall transportation efficiency; Through the data provided by the height detection unit, the real-time height of the coal pile can be accurately grasped, thereby achieving precise control of the coal quantity; at the same time, the slope detection unit can help adjust the slope of the coal pile to ensure that the coal flow remains stable during transportation, reduce the scattering and loss of coal particles, and thus improve transportation efficiency.

[0008] Optionally, the height detection unit includes: Two detection telescopic rods are respectively fixed at two ends of the gantry, the arrangement direction of the two detection telescopic rods is perpendicular to the transportation direction of the frame, and the movable ends of the detection telescopic rods are arranged in a direction close to the conveyor belt; The two ends of the rotating shaft are respectively fixedly connected to the movable ends of the two detection telescopic rods.

[0009] By adopting the above technical scheme, during the transportation of the coal pile, the coal pile squeezes the rotating shaft, the rotating shaft moves upward, the rotating shaft drives the movable end of the detection telescopic rod to move, and the volume of the rodless cavity of the detection telescopic rod changes. By detecting the change in the volume of the rodless cavity of the telescopic rod, the height of the coal pile above the conveyor belt can be measured in real time and accurately, thereby easily improving the response speed and accuracy of the system.

[0010] Optionally, the slope detection unit is provided with a plurality of groups, and the plurality of groups of slope detection units are arranged along the axis direction of the rotating shaft, and the slope detection unit includes: An impeller, the impeller is coaxially sleeved on the rotating shaft and is rotatably connected to the rotating shaft; An induction telescopic rod, wherein the fixed end of the induction telescopic rod is fixedly mounted on the gantry, and the movable end is arranged in a direction close to the impeller; Wherein, during the rotation of the impeller, the impeller can squeeze the movable end of the sensing telescopic rod to move.

[0011] By adopting the above technical solution, when the slope of the coal pile changes, the impeller will rotate accordingly, and the impeller will squeeze the movable end of the sensing telescopic rod to cause it to displace. By real-time monitoring of the displacement of the sensing telescopic rod, the change information of the slope of the coal pile can be obtained in real time and dynamically, thereby improving the measurement accuracy and sensitivity, and being able to accurately reflect the slight changes in the slope of the coal pile.

[0012] Optionally, the flattening component comprises: Two groups of horizontal limit parts are provided, and the two groups of horizontal limit parts are respectively provided on both sides of the frame transportation direction, and the horizontal limit parts are used to gather the coal pile to the middle of the conveyor belt; Two groups of height limiting parts are provided, and the two groups of height limiting parts are respectively provided on the two horizontal limiting parts, and the height limiting parts are used to limit the height of the coal pile; The flattening part is arranged on the frame and is used for lowering the height of the coal pile.

[0013] By adopting the above technical solution, the height detection unit accurately grasps the real-time height of the coal pile. Based on the height data output by the height detection unit, the horizontal limit unit gathers the coal pile to the middle of the conveyor belt to avoid unstable transportation and increased wear caused by the coal pile leaning to one side. At the same time, the slope detection unit detects the slope of the coal pile. Through the slope data output by the slope detection unit, the height limit unit limits the height of the coal pile to prevent overflow caused by the coal pile being too high. When the height of the coal pile exceeds the set value, the flattening unit will automatically start to scrape the coal on the surface of the coal pile and disperse it onto the conveyor belt, thereby easily reducing the overall height of the coal pile, and then easily improving the utilization rate and transportation efficiency of the coal.

[0014] Optionally, the horizontal limiting portion includes: An extrusion telescopic rod is fixed on the frame, the rodless cavity of the extrusion telescopic rod and the rodless cavity of the detection telescopic rod are connected with a guide pipe, and water flows through the guide pipe; A baffle, hinged to the movable end of the extruded telescopic rod; Wherein, the movable ends of the two extrusion telescopic rods are arranged in a direction approaching each other.

[0015] By adopting the above technical scheme, during the transportation of the coal pile, the coal pile squeezes the rotating shaft, the rotating shaft moves upward, the rotating shaft drives the movable end of the detection telescopic rod to move, and the volume of the rodless cavity of the detection telescopic rod is reduced. Since the rodless cavity of the extruding telescopic rod is connected with the rodless cavity of the detection telescopic rod, the volume of the rodless cavity of the extruding telescopic rod increases, the movable end of the extruding telescopic rod moves, and the movable end of the extruding telescopic rod drives the baffle to move. The baffles on both sides push the coal pile to the middle of the conveyor belt, which not only helps to reduce the risk of shaking and landslide of the coal pile during transportation, but also improves transportation efficiency.

[0016] Optionally, the height limiting portion includes: The two ends of the bellows are respectively fixedly connected to the baffle and the movable end of the extrusion telescopic rod, the bellows is connected to the rodless cavity of the induction telescopic rod through a drainage pipe, and water flows through the drainage pipe; The pressure-bearing spring is fixedly arranged in the bellows.

[0017] By adopting the above technical solution, when the slope of the coal pile changes, the impeller will rotate accordingly, and the impeller will squeeze the movable end of the induction telescopic rod to move, and the volume of the rodless cavity of the induction telescopic rod will decrease. Since the bellows is connected to the rodless cavity of the induction telescopic rod, the internal volume of the bellows increases, and the baffle rotates to block the coal pile, effectively preventing overflow caused by the excessively high coal pile or safety hazards during transportation, thereby allowing the conveyor belt to maintain smooth operation during transportation.

[0018] Optionally, the flattening portion includes: A flattening telescopic rod, wherein the fixed end of the flattening telescopic rod is fixedly connected to the frame through a bracket, and the movable end is arranged in a direction close to the conveyor belt, and the rodless cavity of the flattening telescopic rod is connected to the rod cavity of the extruding telescopic rod; The spreading plate is fixedly arranged on the movable end of the spreading telescopic rod, and the spreading plate is arranged tilted.

[0019] By adopting the above technical solution, the volume of the rodless cavity of the extruded telescopic rod increases, and the volume of the rod-containing cavity of the extruded telescopic rod decreases. Since the rodless cavity of the flattened telescopic rod is connected with the rod-containing cavity of the extruded telescopic rod, the volume of the rodless cavity of the flattened telescopic rod increases, and the movable end of the flattened telescopic rod drives the flattening plate to move downward. When the coal pile is high or irregular in shape, the flattening telescopic rod will extend, allowing the flattening plate to contact the coal pile more deeply and perform more effective flattening operations. On the contrary, when the coal pile is low or has a more regular shape, the flattening telescopic rod will shorten, reducing the contact force of the flattening plate on the coal pile, avoiding excessive flattening that causes the coal pile to become loose, which not only improves the transportation efficiency of the equipment, but also enhances the stability and reliability of the equipment.

[0020] Optionally, the driving component includes: Gears, a plurality of which are provided, the plurality of gears correspond to the plurality of rollers one by one, and the gears are coaxially fixedly connected to the rollers; A synchronous belt, wherein the synchronous belt is sleeved on the plurality of gears, and the gears are meshed with the synchronous belt; The motor is fixed on the frame, and the output shaft is coaxially fixedly connected with one of the gears.

[0021] By adopting the above technical solution, the motor drives one of the gears to rotate, the gear drives the synchronous belt to rotate, the synchronous belt drives other gears to rotate, the gear drives the roller to rotate, and the roller drives the conveyor belt to rotate, so that the driving force of the motor can be directly and efficiently transmitted to each roller, thereby improving the transmission efficiency.

[0022] Optionally, the two baffles are bent in a direction away from one end of the conveyor belt toward each other.

[0023] By adopting the above technical solution, the main function of the baffle is to prevent coal from scattering from both sides of the conveyor belt during transportation. By designing the two baffles away from the end of the conveyor belt to bend towards each other, the coal can be blocked more effectively and the possibility of coal scattering due to inertia or vibration can be reduced.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: By setting up gears, synchronous belts and motors, the driving force of the motor can be directly and efficiently transmitted to each roller, thereby improving the transmission efficiency; By setting up a gantry, height detection unit and slope detection unit, the coal flow is ensured to remain stable during transportation, reducing the scattering and loss of coal particles, thereby improving transportation efficiency; By arranging the horizontal limiting part, the height limiting part and the flattening part, it is easy to reduce the overall height of the coal pile, thereby making it easy to improve the utilization rate and transportation efficiency of the coal.
