Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, and in particular to a mobile scraper conveyor. Background Technology

[0002] A scraper conveyor is a conveyor that uses a scraper chain to pull and transport bulk materials in a trough. It can be used for horizontal or inclined transport.

[0003] In modern industrial production, the material conveying system between silos and production lines is a key link in ensuring continuous production. In existing technologies, there is a general problem of insufficient flexibility in the layout of conveying equipment for material supply to production lines with multiple silos. Taking typical fields such as feed processing and grain storage as examples, when the production line needs to obtain materials from silos in multiple different locations, traditional conveying equipment is mostly fixed and lacks reliable mobile support mechanisms. When it is necessary to switch the feeding silos, it is necessary to move the entire silo using auxiliary equipment such as forklifts, which is time-consuming and labor-intensive. Utility Model Content

The axis of the hinge shaft is perpendicular to the sliding direction of the sliding plate, and the end of the diagonal brace away from the displacement plate is hinged to the sliding plate by a pin.

[0010] The effect achieved by the above components is as follows: by driving the rotating shaft to rotate by the motor, the scraper conveyor is tilted, thereby realizing continuous adjustment of the discharge pipe height. This eliminates the need to disassemble the equipment or use auxiliary tools such as forklifts, making it easy to quickly adapt to silo discharge ports of different heights.

[0011] Preferably, the surface of the scraper conveyor is provided with an angle adjustment device, which includes two vertical plates fixedly installed on the surface of the scraper conveyor. The surfaces of the two vertical plates are rotatably connected to rotating rods via tapered roller bearings. A feed pipe is fixedly installed between the two rotating rods via a coupling.

[0014] The effect achieved by the above components is that the electric telescopic rod drives the gear and rack transmission to rotate the feed pipe, which can flexibly adjust the feed angle to adapt to the horizontal offset requirements of the silo outlet, without the need for additional auxiliary components such as the steering funnel.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting up a height adjustment device, the rotating shaft driven by the motor is rotated, which in turn drives the scraper conveyor to tilt, thereby realizing continuous adjustment of the discharge pipe height.

In order to achieve accurate conversion from the rotational motion of the motor 206 to the linear motion of the displacement plate 209 and avoid adjustment errors caused by slippage, the motor 206 can be connected to the displacement plate 209 through a synchronous belt transmission mechanism. The synchronous belt model is HTD-5M-600.

[0025] Reference Figure 2-5As shown in this embodiment: the surface of the scraper conveyor 204 is provided with an angle adjustment device 3. The angle adjustment device 3 includes two vertical plates 301 fixedly installed on the surface of the scraper conveyor 204. The surfaces of the two vertical plates 301 are rotatably connected to rotating rods 302 through tapered roller bearings. A feed pipe 303 is fixedly installed between the two rotating rods 302 through a coupling. The surface of the scraper conveyor 204 is provided with a long groove 304. An L-shaped plate 305 is slidably connected inside the long groove 304. A rack 306 is fixedly installed at the end of the L-shaped plate 305 away from the long groove 304. A gear 307 is fixedly installed on the outer wall surface of one of the rotating rods 302 through a key connection. The gear 307 and the rack 306 are connected together. The components mesh with each other. A transverse groove 308 is provided on one side surface of the scraper conveyor 204. A slide plate 309 is slidably connected inside the transverse groove 308. A connecting rod 310 is fixedly installed between the slide plate 309 and the rack 306. A rectangular plate 311 is fixedly installed on one side surface of the scraper conveyor 204. An electric telescopic rod 312 is fixedly installed on the surface of the rectangular plate 311. The output end of the electric telescopic rod 312 is fixedly connected to the slide plate 309. The electric telescopic rod 312 is electrically connected to the PLC controller 207. The gear 307 has a module of 2 and a meshing clearance with the rack 306 of ≤0.1mm. The electric telescopic rod 312 is model JEA-100 and has a stroke of 150mm.

[0026] Working principle: When the device is needed, the installation position and moving path of the scraper conveyor 204 are first determined according to the position of the outlet equipment of each silo (silo 1, 2, 3, 6) and the position of the feed equipment of the second phase production. Release the brake on pulley 4 and flexibly adjust the direction of the equipment by rotating pulley 4 in all directions. Move the scraper conveyor 204 to a position close to the target silo outlet, so that the feed pipe 303 is roughly aligned with the silo outlet. Then lock the brake on pulley 4 to complete the initial positioning. Then, according to the outlet height of the silo outlet, input the target height parameter through the PLC controller 207. The PLC controller 207 sends a start command to the motor 206. The output shaft of the motor 206 drives the rotating shaft 202 to rotate through the coupling. At this time, the rotating shaft 202 rotates smoothly in the U-shaped long frame 201 through the deep groove ball bearing, which in turn drives the rotating plate 203 fixed on the rotating shaft 202 to rotate synchronously. When the rotating plate 203 rotates, it pushes the scraper conveyor 204 to tilt around the axis of the rotating shaft 202, so that the height of the discharge pipe 205 changes. During the tilting process of the scraper conveyor 204, the sliding plate 212 at its bottom slides synchronously in the chute 211. The sliding plate 212 is hinged to the displacement plate 209 in the groove 208 of the base 1 via the inclined support plate 210. At this time, the servo motor 206 drives the displacement plate 209 to move linearly in the groove 208 through the synchronous belt transmission mechanism. The precise transmission ratio of the synchronous belt ensures that the moving distance of the displacement plate 209 is precisely matched with the tilt angle of the scraper conveyor 204. At the same time, the angle sensor embedded on the surface of the base 1 monitors the tilt angle of the rotating plate 203 in real time and feeds the data back to the PLC controller 207. When the tilt angle deviation exceeds ±1°, the PLC controller 207 automatically adjusts the direction of the motor 206 until the height of the discharge pipe 205 reaches the preset value and then the motor 206 is turned off. Then, according to the horizontal offset angle of the discharge port of the silo discharge equipment, the docking angle of the feed pipe 303 needs to be adjusted. The target angle parameter is input into the interface of the PLC controller 207, the electric telescopic rod 312 is started and extended, pushing the slide plate 309 to slide in the transverse groove 308.The slide plate 309 drives the rack 306 to move along the long groove 304 via the connecting rod 310. The rack 306 meshes with the gear 307, driving the rotating rod 302 to rotate around the tapered roller bearing, which in turn drives the feed pipe 303 to rotate. During this process, the meshing backlash between the gear 307 and the rack 306 is controlled to ≤0.1mm to ensure rotational accuracy. When the feed pipe 303 rotates to the target angle, the electric telescopic rod 312 stops moving and locks its position through the sliding engagement of the L-shaped plate 305 and the long groove 304. The PLC controller 20... 7. Based on the feedback from the displacement encoder built into the electric telescopic rod 312, confirm that the angle adjustment of the feed pipe 303 is complete. After completing the height and angle adjustment, check whether the feed pipe 303 is aligned with the silo outlet and the flange interface of the discharge pipe 205 is aligned with the feed equipment of the second phase production line. Ensure the connection is sealed by the sealing ring. Then start the scraper chain inside the scraper conveyor 204. The material enters the scraper conveyor trough from the silo through the feed pipe 303 and is driven by the scraper chain to be conveyed along the trough to the discharge pipe 205, and finally enters the second phase production line.
