Description

Technical Field

[0001] This utility model relates to the technical field of chute devices, specifically to an adjustable chute device. Background Technology

[0002] In bulk ore loading and unloading operations, ore is often transferred by chute and belt conveyor. The ore is on the chute and is subject to its own gravity. The ore slides along the chute and is transferred to the belt. The belt is usually set on the lower side of the chute. The ore is then transported to the designated location by the belt conveyor. In the existing process of using sluices to transport ore, sticky materials such as Newman powder are prone to forming arches in the sluice, resulting in poor material flow. At the same time, because there is no dynamic adjustment function in the initial design, the flow of ore in the sluice is difficult to control. After the ore is transferred from the sluice to the belt conveyor, the ore on the belt may be irregularly dispersed, which may cause the belt to run off-track and affect the efficiency of operation. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide an adjustable chute device, which solves the technical problem that the flow of ore in the chute is difficult to control and is prone to clogging in the prior art.

[0004] According to one aspect, at least one embodiment of the present invention provides an adjustable sluice box device, including a sluice box body, an air jet mechanism, an adjustment plate, and an adjustment mechanism. The air jet mechanism is disposed above one end of the sluice box body and is used to jet air toward the sluice box body to push the transfer of ore. Two adjustment plates are symmetrically and rotatably disposed within the sluice box body. The adjustment mechanism is disposed within the sluice box body and is used to adjust the included angle between the two adjustment plates.

[0005] Preferably, the jetting mechanism includes a mounting plate, a negative pressure fan, a jetting pipe, and a connecting pipe. The mounting plate is fixedly disposed on the top of one end of the chute body. The negative pressure fan is mounted on the mounting plate. The jetting pipe is fixedly connected to one end of the mounting plate. Multiple jetting ports are connected to the jetting pipe. One end of the connecting pipe is connected to the output end of the negative pressure fan, and the other end is connected to the jetting pipe.

[0006] Furthermore, the adjustment mechanism includes a first rotating shaft, a second rotating shaft, and a drive assembly. Two first rotating shafts are rotatably disposed within the chute body. The first rotating shaft is fixedly connected to one end of the adjustment plate. The second rotating shaft is rotatably disposed within the chute body. The first rotating shaft is fitted onto the second rotating shaft and is coaxially fixedly connected to the second rotating shaft. The drive assembly is disposed within the chute body and is used to drive the two adjustment plates to rotate.

[0007] Furthermore, the drive assembly includes a worm gear, a connecting shaft, a worm, and a drive motor. One end of each of the two second rotating shafts is coaxially and fixedly connected to the worm gear. The connecting shaft is rotatably disposed at the bottom end of the chute body. Both ends of the connecting shaft are coaxially and fixedly connected to the worm. The two worms mesh with the two worm gears respectively. The drive motor is mounted on the chute body, and the output end of the drive motor is coaxially and fixedly connected to one end of one of the worms.

[0008] As a further aspect of this application, in order to prevent ore from sticking to the inner wall of the chute body and to allow for rapid flow, a wear-resistant and smooth lining plate is provided on the inner side wall of the chute body.

[0009] As a further aspect of this application, in order to move and completely cover the ore inside the sluice body by blowing, a plurality of the jet nozzles are evenly initially arranged on the jet pipe and tilted toward the sluice body.

[0010] Based on the aforementioned scheme, in order to enable the two worm gears to drive the two worm wheels to rotate in opposite directions during the rotation of the two worms, the helical directions of the two worms are opposite.

[0011] Furthermore, in order to enable the ore to be transferred quickly under the guidance of the two adjusting plates, the first rotating shaft is located inside the chute body, one end of the adjusting plate is tangent to the first rotating shaft, and the surface of the adjusting plate is smooth.

[0012] The beneficial effects of this utility model are as follows: 1. In this utility model, by setting up an air jet mechanism, by starting a negative pressure fan, multiple air jet nozzles are tilted towards the bottom wall of the chute body to jet air. The jetted gas will blow the movement of the ore inside the chute body, thereby assisting in the transfer of the ore. 2. In this utility model, through the cooperation of the chute body, the adjusting plate and the adjusting mechanism, the drive motor is started to drive the two adjusting plates to rotate with the axes of the two first rotating shafts as the center (one counterclockwise and one clockwise). This adjusts the "angle" between the two adjusting plates in the chute body, thereby adjusting the flow range of the ore in the chute body, preventing the ore from being transferred to the belt and causing the belt to run off-center, and also preventing the ore from clogging in the chute body, thus speeding up the ore transportation.

[0022] like Figures 1-4 As shown, it illustrates an adjustable sluice device according to an embodiment of the present invention. The adjustable sluice device includes a sluice body 1. In order to prevent ore from sticking to the inner wall of the sluice body 1 and to allow for rapid flow, a wear-resistant and smooth liner 14 is provided on the inner side wall of the sluice body 1. The liner 14 is U-shaped. It also includes an air jet mechanism, an adjustment plate 2 and an adjustment mechanism. like Figure 1 As shown, the jetting mechanism is located above one end of the sluice body 1 and is used to jet gas toward the sluice body 1 to push the transfer of ore. The jetting mechanism includes a mounting plate 3, a negative pressure fan 4, a jetting pipe 5, and a connecting pipe 7. The mounting plate 3 is fixedly located on the top of one end of the sluice body 1. The negative pressure fan 4 is mounted on the mounting plate 3. The jetting pipe 5 is fixedly connected to one end of the mounting plate 3. Multiple jetting ports 6 are connected to the jetting pipe 5. One end of the connecting pipe 7 is connected to the output end of the negative pressure fan 4, and the other end is connected to the jetting pipe 5. In order to blow the ore inside the sluice body 1 and completely cover it, multiple jetting ports 6 are evenly arranged on the jetting pipe 5 and tilted toward the sluice body 1. By starting the negative pressure fan 4, the negative pressure fan 4 collects the outside air and transfers it to the jetting pipe 5 through the connecting pipe 7. Then, it is transferred to multiple jetting ports 6 and sprayed at an angle toward the bottom wall of the sluice body 1. The sprayed gas blows the ore inside the sluice body 1 to move, thus assisting in the transfer of ore. It should be added that a conveyor belt is provided below the other end of the sluice body 1 to receive the ore transferred from the sluice body 1 and to carry out subsequent smooth transportation. In addition, the sluice body 1 is usually set at an angle, and the jetting mechanism is located at the higher end of the inclined sluice body 1. It should also be added that the ore transported in the sluice body 1 is adhesive and generates less dust. Two adjusting plates 2 are symmetrically and rotatably arranged inside the chute body 1. An adjusting mechanism is set inside the chute body 1 to adjust the included angle between the two adjusting plates 2. The adjusting mechanism includes a first rotating shaft 8, a second rotating shaft 9 and a driving assembly. Two first rotating shafts 8 are rotatably arranged inside the chute body 1. In order to enable the ore to be transferred quickly under the guidance of the two adjusting plates 2, the first rotating shaft 8 is partially located inside the chute body 1. One end of the adjusting plate 2 is tangent to the first rotating shaft 8. The surface of the adjusting plate 2 is smooth. The first rotating shaft 8 is fixedly connected to one end of the adjusting plate 2. The second rotating shaft 9 is rotatably arranged inside the chute body 1. The first rotating shaft 8 is fitted on the second rotating shaft 9 and is coaxially and fixedly connected to the second rotating shaft 9. like Figure 2 and Figure 4 As shown, the drive assembly is installed inside the chute body 1 to drive the two adjusting plates 2 to rotate. The drive assembly includes a worm gear 10, a connecting shaft 11, a worm 12, and a drive motor 13. One end of each of the two second rotating shafts 9 is coaxially fixedly connected to a worm gear 10. The connecting shaft 11 is rotatably installed at the bottom end of the chute body 1. Both ends of the connecting shaft 11 are coaxially fixedly connected to worms 12. The two worms 12 mesh with the two worm gears 10 respectively. In order to enable the two worms 12 to drive the two worm gears 10 to rotate in opposite directions during rotation, the spiral directions of the two worms 12 are opposite. The drive motor 13 is installed on the chute body 1. The output end of the drive motor 13 is coaxially fixedly connected to one end of a worm 12. A cavity 15 is opened inside the chute body 1 to cooperate with the drive mechanism. The worm gear 10, worm 12, and connecting shaft 11 are all rotatably installed inside the cavity 15. Specifically, by starting the drive motor 13, the output end of the drive motor 13 rotates, driving one worm gear 12 to rotate. The rotation of the worm gear 12 drives the connecting shaft 11 to rotate, and the rotation of the connecting shaft 11 drives the other worm gear 12 to rotate. This allows the drive motor 13 to simultaneously drive both worm gears 12 to rotate. Since the two worm gears 12 mesh with the two worm wheels 10 respectively and the helix directions of the two worm gears 12 are opposite, the rotation of the two worm gears 12 drives the two worm wheels 10 to rotate in opposite directions (one counterclockwise and one clockwise). The two worm wheels 10 respectively drive the two second rotating shafts 9 to rotate, and the two second rotating shafts 9 respectively drive the two worm wheels 10 to rotate. The two first rotating shafts 8 rotate, and the two first rotating shafts 8 drive the two adjusting plates 2 to rotate. The two adjusting plates 2 rotate with the axes of the two first rotating shafts 8 as the center (one counterclockwise and one clockwise). Since the worm gear 10 and worm 12 have self-locking properties and the drive motor 13 is a forward and reverse motor, the adjusting plates 2 can be kept stable. This adjusts the "angle" between the two adjusting plates 2 in the chute body 1, thereby adjusting the flow range of ore in the chute body 1, preventing ore from being transferred to the belt and causing belt deviation, and also preventing ore from clogging in the chute body 1, thus speeding up the ore conveying. It should be added that the drive motor 13 is equipped with a controller, which allows the operator to remotely start the drive motor 13 to adjust the angle between the two adjustment plates 2. Working principle: When the adjustable chute device is conveying ore, it transfers the ore to the higher end of the inclined chute body 1. Due to the adhesiveness of the ore, it slides along the chute body 1 under its own gravity, but the transfer speed is slow. By starting the negative pressure fan 4, the negative pressure fan 4 collects the outside air and transfers it to the jet pipe 5 through the connecting pipe 7. Then, it transfers the air to multiple jet nozzles 6 and sprays it at an angle towards the bottom wall of the chute body 1. The sprayed gas blows the ore inside the chute body 1 and assists in the transfer of the ore. By starting the drive motor 13, the output end of the drive motor 13 rotates, driving one worm gear 12 to rotate. The rotation of the worm gear 12 drives the connecting shaft 11 to rotate, and the rotation of the connecting shaft 11 drives the other worm gear 12 to rotate. This causes the drive motor 13 to simultaneously drive both worm gears 12 to rotate. Since the two worm gears 12 mesh with two worm wheels 10 respectively, and the helical directions of the two worm gears 12 are opposite, the rotation of the two worm gears 12 drives the two worm wheels 10 to rotate in opposite directions (one counterclockwise, one clockwise). The two worm wheels 10 respectively drive the two second rotating shafts 9 to rotate, and the two second rotating shafts 9 in turn drive the two... The first rotating shaft 8 rotates, and the two first rotating shafts 8 drive the two adjusting plates 2 to rotate respectively. The two adjusting plates 2 rotate with the axes of the two first rotating shafts 8 as the center (one counterclockwise and one clockwise). Since the worm gear 10 and worm 12 have self-locking properties and the drive motor 13 is a forward and reverse motor, the stability of the adjusting plates 2 can be maintained. This adjusts the "angle" between the two adjusting plates 2 in the chute body 1, thereby adjusting the flow range of ore in the chute body 1, preventing ore from being transferred to the belt and causing belt deviation, and also preventing ore from clogging in the chute body 1, thus speeding up the ore conveying. The ore is then transferred from the chute body 1 to the belt conveyor located below the chute body 1 for further transport.
