[0024] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] See Figures 1-5 As shown, a scraper conveyor for a drilling rig includes a loading device 1, a scraper chain 2, a conveying trough 3, a tensioning device 4, and a drive device 5. The loading device 1 is connected to the first end of the conveying trough 3. The scraper chain 2 is installed inside the conveying trough 3. The tensioning device 4 includes a tensioning slider 503 and an elastic element. The tensioning slider 503 is slidably installed on the side wall of the second end of the conveying trough 3. The elastic element is connected between the side wall of the conveying trough 3 and the tensioning slider 503. The drive device 5 is installed on the tensioning slider 503 and is driven by the scraper chain 2.

[0026] Specifically, this utility model achieves chain locking of the scraper chain 2 through the tensioning device 4, the chain pressure plate 301 and the sleeve-shaped driven sprocket 101, and improves the transport capacity on steep slopes through the arc-shaped and heightened scraper 201, thus making it suitable for drilling and exploration rigs to operate on slopes.

[0027] Preferred, such as Figure 4As shown, the elastic element includes a telescopic rod and a spring cylinder 402. The first end of the telescopic rod is connected to the side wall of the transport trough 3, and the second end of the telescopic rod is connected to the first end of the spring cylinder 402. The second end of the spring cylinder 402 is connected to the tensioning slider 503. Specifically, the telescopic rod can be a hydraulic cylinder 403, a pneumatic cylinder, or an electric telescopic rod. In this embodiment, the telescopic rod is a hydraulic cylinder 403. The extension and retraction of the hydraulic cylinder 403 can further increase the stroke of the spring cylinder 402, thereby ensuring the tension force on the scraper chain 2. When the entire scraper 201 conveyor travels, the loading trough 104 is raised by the loading hydraulic cylinder 403, and the distance between the driving sprocket 501 and the driven sprocket 101 becomes shorter. The spring force inside the spring cylinder 402 causes the tensioning slider 503 to move backward, realizing automatic chain tensioning and avoiding chain jamming.

[0028] Preferably, the tensioning slider 503 is provided with a tensioning front seat 401 for connecting the spring cylinder 402, and the side wall of the transport trough 3 is provided with a tensioning rear seat 404 for connecting the telescopic rod. Specifically, a groove is provided on the side of the second end of the transport trough 3, and the tensioning slider 503 is installed in the groove. There are two tensioning devices 4, which are located on opposite sides of the transport trough 3.

[0029] Preferred, such as Figure 2 As shown, the loading device 1 includes a loading trough 104, a star wheel 103, and a loading lifting cylinder 102. The loading trough 104 is rotatably connected to the first end of the transport trough 3. The star wheel 103 is rotatably installed inside the loading trough 104. The loading lifting cylinder 102 is used to adjust the angle of the loading trough 104 and is installed at the bottom of the loading trough 104. Specifically, the lifting cylinder 102 is connected between the body of the drilling and loading rig and the loading trough 104, thereby realizing the angle adjustment of the loading trough 104, facilitating the contact of the loading trough 104 with the ground during travel and the loading of ore during coal mining on steep slopes.

[0030] Preferably, there are two star wheels 103, which are installed at intervals within the loading trough 104 and rotate in opposite directions to load coal ore from the loading trough 104 into the transport trough 3. Both star wheels 103 must rotate in opposite directions to move the ore in the loading trough 104 towards one side of the transport trough 3.

[0031] Preferred, such as Figures 2-4As shown, the scraper chain 2 includes a scraper 201, a roller chain 202, a drive sprocket 501, and a driven sprocket 101. The drive sprocket 501 is rotatably mounted on the tension slider 503 and connected to the drive device 5. The driven sprocket 101 is rotatably mounted in the loading trough 104. The roller chain 202 is wound around the drive sprocket 501 and the driven sprocket 101. The scraper 201 is mounted on the roller chain 202. The driven sprocket 101 is in the shape of a sleeve. The drive device 5 can be a drive motor 502. The output shaft of the drive motor 502 is fixed to the drive sprocket 501, thereby driving the drive sprocket 501 to rotate, which in turn drives the roller chain 202 to move, thus achieving the effect of moving the coal ore fed by the star wheel 103 from the loading trough 104 to the rear. The driven sprocket 101 is in the form of a sleeve, which can reduce the risk of chain jamming.

[0032] Preferably, the scraper 201 has an arc-shaped cross-section, and the height of the scraper 201 is increased, thereby improving the transportation capacity for ore mining on steep slopes. There are two roller chains 202, installed alternately. There are multiple scraper chains 201, installed alternately and parallel to each other along the length of the roller chains 202 between the two roller chains 202.

[0033] Preferred, such as Figure 5 As shown, the transport trough 3 includes a trough body 302, which has a curved section to provide more installation space for other components of the drilling rig.

[0034] Preferably, the transport trough 3 further includes a plurality of chain rollers 303 spaced apart at the bottom of the curved section. The plurality of chain rollers 303 support the roller chain 202 to ensure that the scraper 201 and the bottom plate of the trough 302 maintain a certain gap, thereby reducing the wear of the scraper 201.

[0035] Preferably, the two ends of the side plate of the trough 302 are provided with chain pressure plates 301 above the roller chain 202 to prevent the roller chain 202 from jumping. In this embodiment, the number of chain pressure plates 301 is at least two, and the at least two chain pressure plates 301 are respectively located at at least two ends of the curved section.

[0036] This utility model relates to a scraper conveyor for drilling and exploration rigs. Through elastic elements and a tensioning slider 503, the scraper chain 2 is automatically tensioned during slope mining to prevent chain jamming. This solves the technical problem of chain jamming in existing scraper conveyors (201) during shovel movement. This utility model designs the scraper 201 as an arc shape and increases its height, improving transport capacity on steep slopes. A chain support wheel 303 is installed on the curved section of the transport trough 3 to reduce wear on the scraper 201. A sleeve-shaped driven sprocket 101, a tensioning device 4, and a chain pressure device are used to prevent chain jamming.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
