Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a scraper conveyor. Background Art

[0002] A scraper conveyor, also known as a scraper conveyor, is a continuous transport equipment that transports bulk materials in a closed rectangular cross-section shell with the help of a moving scraper chain. It is widely used in coal mining, metallurgy, building materials, electric power, chemical industry, cement, ports, docks, grain and oil, food, feed and other industries.

[0003] In existing technologies, when conveying thin coal seams, scraper conveyors often encounter a problem: when coal at the shearer's output falls onto the roadway floor, the overall height of the conveyor becomes relatively high due to the scraper conveyor's two-tier drive chain design. This creates inconvenience for workers, making it difficult to push the fallen coal back onto the scraper conveyor. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a scraper conveyor which can facilitate workers to push coal dropped on the tunnel floor back onto the bottom plate.

[0005] The utility model is realized through the following technical solution, which provides a scraper conveyor, including a base plate, an annular rope arranged above the base plate and a driving mechanism for driving the annular rope to rotate, the plane where the annular rope is located extends laterally, a plurality of scrapers are fixed to the annular rope, and the plurality of scrapers are distributed along the circumference of the annular rope, and one side edge of the annular rope is located between the left support part and the right support part of the coal mining machine.

[0006] The utility model is in use, by setting a bottom plate, an annular rope and a driving mechanism for driving the annular rope to rotate are set above the bottom plate, and the plane where the annular rope is located extends horizontally, and a plurality of scrapers are set on the annular rope, and the plurality of scrapers are distributed along the circumference of the annular rope, and one side edge of the annular rope is located between the left support part and the right support part of the coal mining machine. When the device is in use, after the coal mining machine collects the coal, the collected coal will fall onto the movement trajectory of the scraper on the bottom plate between the left support part and the right support part of the coal mining machine through the output end of the coal mining machine, and then the annular rope is driven to rotate by the driving mechanism, so that the scraper rotates under the drive mechanism, thereby pushing the coal fallen on the bottom plate to move, and pushing the coal to the next working station. In this process, part of the coal falling from the output end of the coal mining machine will fall onto the roadway ground. At this time, because the annular rope is rotated from vertical to horizontal, it is distributed from the previous upper and lower layers to the left and right layers, which will reduce the height of the device, so that it is convenient for the staff to push the coal fallen on the roadway ground back to the device.

[0007] Preferably, the drive mechanism includes a transmission wheel engaged with the endless rope, one end of the scraper is fixedly connected to the outer circumference of the endless rope, and the other end of the scraper extends away from the endless rope. The drive mechanism includes a transmission wheel engaged with the endless rope, one end of the scraper is fixedly connected to the outer circumference of the endless rope, and the other end of the scraper extends away from the endless rope. The transmission wheel can facilitate the operator to drive the endless rope to rotate, thereby driving the scraper to rotate and moving the coal that has fallen on the bottom plate.

[0008] Preferably, the endless rope is configured as an endless chain, and the transmission wheel is configured as a sprocket adapted to the endless chain. By configuring the endless rope as an endless chain and the transmission wheel as a sprocket adapted to the endless chain, the endless chain and sprocket can improve the durability of the device during use and the convenience of maintenance.

[0009] Preferably, a vertical rotating motor is provided on the bottom plate, and the sprocket is fixedly connected to the rotating shaft of the vertical rotating motor. By providing the vertical rotating motor on the bottom plate and fixing the sprocket to the rotating shaft of the vertical rotating motor, the vertical rotating motor can be used to facilitate the staff to drive the sprocket to rotate.

[0010] Preferably, the shaft of the vertical rotating motor faces downwards. By making the shaft of the vertical rotating motor face downwards, the vertical distance between the chain and the roadway ground can be further reduced, thereby making it easier for workers to push fallen coal back onto the scraper conveyor.

[0011] Preferably, a connecting plate is provided above the vertical rotating motor, the lower end surface of the connecting plate being fixedly connected to the upper end surface of the base plate via a support rod, and the vertical rotating motor being mounted on the lower end surface of the connecting plate. By providing the connecting plate above the vertical rotating motor, the lower end surface of the connecting plate being fixedly connected to the upper end surface of the base plate via a support rod, and the vertical rotating motor being mounted on the lower end surface of the connecting plate, the use of the connecting plate and the support rod can improve the stability of the vertical rotating motor during use of the device.

[0012] Preferably, a push seat is installed on the bottom plate, and the push seat is located on the side wall of the bottom plate away from the coal shearer. By installing the push seat on the bottom plate, the push seat is located on the side wall of the bottom plate away from the coal shearer, and connecting the push seat with the hydraulic support, it is convenient for workers to move the device.

[0013] Preferably, the lower end surface of the scraper is flush with the upper end surface of the bottom plate. By making the lower end surface of the scraper flush with the upper end surface of the bottom plate, the coal transportation efficiency can be improved and the coal residue on the bottom plate can be reduced.

[0014] The beneficial effects of the present invention are as follows: by arranging a bottom plate, an annular rope and a driving mechanism for driving the annular rope to rotate are arranged above the bottom plate, and the plane where the annular rope is located extends horizontally, and a plurality of scrapers are arranged on the annular rope, and the plurality of scrapers are distributed along the circumference of the annular rope, and one side edge of the annular rope is located between the left support part and the right support part of the coal mining machine. When the device is in use, after the coal mining machine collects the coal, the collected coal will fall onto the movement trajectory of the scraper on the bottom plate between the left support part and the right support part of the coal mining machine through the output end of the coal mining machine, and then the annular rope is driven to rotate by the driving mechanism, so that the scraper rotates under the drive mechanism, thereby pushing the coal fallen on the bottom plate to move and push the coal to the next working station. In this process, part of the coal falling from the output end of the coal mining machine will fall onto the roadway ground. At this time, because the annular rope is turned from vertical to horizontal, it is changed from the previous upper and lower layers to the left and right distribution, which will reduce the height of the device, thereby making it convenient for the staff to push the coal fallen on the roadway ground back to the device.

[0021] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0022] like Figures 1-4 The scraper conveyor of the utility model shown in the figure includes a base plate 3, an annular rope arranged above the base plate 3 and a driving mechanism for driving the annular rope to rotate. The plane where the annular rope is located extends laterally. A plurality of scrapers 5 are fixed to the annular rope. The plurality of scrapers 5 are distributed along the circumference of the annular rope. One side edge of the annular rope is located between the left support part of the coal mining machine 2 and the right support part of the coal mining machine 2.

[0023] The drive mechanism includes a transmission wheel that engages with an endless rope. One end of a scraper 5 is fixedly attached to the outer circumference of the endless rope, while the other end of the scraper 5 extends away from the endless rope. The transmission wheel facilitates the rotation of the endless rope, driving the scraper 5 to rotate and displacing coal that has fallen onto the base plate 3. By configuring the endless rope as an endless chain 4 and the transmission wheel as a sprocket 7 compatible with the endless chain 4, the endless chain 4 and sprocket 7 enhance the durability of the device during use and ease of maintenance. A vertical rotary motor 9 is provided on the base plate 3, with the sprocket 7 fixedly attached to the rotating shaft of the vertical rotary motor 9. This facilitates the rotation of the sprocket 7 by the vertical rotary motor 9. By angling the rotating shaft of the vertical rotary motor 9 downward, the vertical distance between the chain and the roadway floor is further reduced, making it easier for workers to push fallen coal back onto the scraper conveyor. A connecting plate 1 is provided above the vertical rotary motor 9. The lower end of the connecting plate 1 is fixedly connected to the upper end of the base plate 3 via a support rod 8. The vertical rotary motor 9 is mounted on the lower end of the connecting plate 1. The connecting plate 1 and the support rod 8 improve the stability of the vertical rotary motor 9 during use. A sliding seat 6 is installed on the base plate 3. The sliding seat 6 is located on the side wall of the base plate 3 away from the coal mining machine 2. The sliding seat 6 is connected to the hydraulic support, making it easier for workers to move the device. By aligning the lower end of the scraper 5 with the upper end of the base plate 3, the efficiency of coal transportation can be improved and the amount of coal left on the base plate 3 can be reduced. The right support of the coal mining machine 2 is engaged with a rack fixedly connected to the top of the base plate 3. The left support of the coal mining machine 2 is slidably connected to the top of the base plate 3, making it easier for the coal mining machine 2 to move on the base plate 3. After the shearer 2 collects the coal, the collected coal falls from the output end of the shearer 2 onto the movement trajectory of the scraper 5 on the bottom plate 3 between the left and right support parts of the shearer 2. This ensures that the scraper 5 pushes the coal that has fallen on the bottom plate 3 between the left and right support parts of the shearer 2 to move it and push it to the next workstation. The movement direction of the endless chain 4 between the left and right support parts of the shearer 2 is consistent with the movement direction of the shearer 2 on the bottom plate 3, which facilitates the scraper 5 to push the coal that has fallen on the bottom plate 3 between the left and right support parts of the shearer 2 to move it.

[0024] Combined with attachment Figure 1-4It can be seen that the method of using the present invention is as follows: First, when the device is in use, after the coal mining machine 2 collects the coal, the collected coal will fall through the output end of the coal mining machine 2 onto the movement trajectory of the scraper 5 on the bottom plate 3 between the left support part and the right support part of the coal mining machine 2, and then the rotating motor 9 on the connecting plate 1 is started to make the rotating motor 9 drive the sprocket 7 to rotate, thereby driving the ring chain 4 to rotate, and driving several slides on the ring chain 4 to rotate, so that the scraper 5 pushes the coal fallen on the bottom plate 3 to move, and pushes the coal to the next work station. In this process, part of the coal falling from the output end of the coal mining machine 2 will fall on the roadway ground. At this time, because the ring chain 4 is turned from vertical to horizontal, it changes from the previous upper and lower layers to left and right distribution, which will reduce the height of the device, so that it can be convenient for the staff to push the coal fallen on the roadway ground back to the device.
