Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal washing and beneficiation technology, specifically to a chute flap structure. Background Technology
[0002] The chute is one of the important transportation equipment in a coal preparation plant. It is mainly used between production equipment, between production equipment and transportation equipment, and between transportation equipment to facilitate the transfer and transportation of materials. Its main functions include: transition, transportation, sealing, centralized distribution, equal distribution, and adjustment of process flow. In a coal preparation plant, since there are multiple coal bunkers, the chute needs to branch out into multiple branches to achieve the purpose of sending materials to different coal bunkers.
[0003] In the renovation of coal preparation plants, the old-style tilting plate hydraulic push rod base and chute are separate structures, which require a large space and have few welds, making them prone to damage. In addition, some tilting plates require manual flipping, which is labor-intensive and has low production efficiency.
[0004] The new flap structure requires only half the space of the original flap structure, and the hydraulic push rod base is directly welded to the chute, greatly improving its sturdiness. Summary of the Invention
[0005] The present invention aims to solve the technical problems mentioned in the background section above by providing a chute flap structure that saves floor space, reduces workload, and improves production efficiency.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a flip-plate structure for a chute, the chute including a first channel, one side of the first channel being connected to a second channel, the first channel being provided with a through and rotatable flipping shaft, a flip plate being fixedly connected to the flipping shaft and disposed inside the chute, one end of the flipping shaft extending out of the chute and connected to a telescopic push rod via a cam assembly, the telescopic push rod being fixedly connected to the side wall of the chute, when the telescopic push rod extends, it can cause the flipping shaft to rotate and drive the flip plate to rotate counterclockwise, when the telescopic push rod retracts, it can cause the flipping shaft to rotate and drive the flip plate to rotate clockwise.
[0007] In some embodiments, the cam assembly includes a first cam and a second cam. The upper end of the first cam is hinged to the lower end of the telescopic rod of the telescopic push rod, and the lower end of the first cam is hinged to the upper end of the second cam. The lower end of the second cam is fixedly connected to one end of the flip shaft. When the telescopic push rod is in the retracted state, the axes of the first cam and the second cam form an obtuse angle, and when the telescopic push rod is in the extended state, the axes of the first cam and the second cam form an acute angle.
[0008] In some embodiments, a flap is located at the intersection of the first and second channels. When the telescopic push rod is in the retracted state, the flap blocks the first channel and opens the second channel; when the telescopic push rod is in the extended state, the flap blocks the second channel and opens the first channel.
[0009] In some embodiments, the two ends of the tilting shaft are mounted in bearing housings, which are fixedly connected to the sidewalls of the chute.
[0010] In some embodiments, the telescopic push rod is arranged along the extension direction of the first channel and is fixedly connected to the outer wall of the chute via a push rod base.
[0011] In some embodiments, the flipping shaft is a hollow round steel bar, the length of which is longer than the width of the chute. The upper part of the hollow round steel bar is slotted, and the flip plate is embedded into the slot and then welded for reinforcement.
[0012] In some embodiments, the hinge joints of the first cam and the second cam are both hinged using cylindrical pins.
[0013] In some embodiments, the telescopic push rod is a hydraulically driven hydraulic telescopic rod.

[0023] The present invention will now be described in further detail.
[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0025] A chute flap structure, such as Figure 1 , Figure 2 As shown, the chute includes a first channel 1 and a second channel 2. The first channel 1 is a vertical channel, and the second channel 2 is located on the side and connected to the first channel 1. A flap 3 is located at the intersection of the first channel 1 and the second channel 2. When the telescopic push rod 4 is in the retracted state, the flap 3 blocks the first channel 1 and opens the second channel 2; when the telescopic push rod 4 is in the extended state, the flap 3 blocks the second channel 2 and opens the first channel 1.
[0026] The flipping shaft 5 passes through the first channel 1. The flipping shaft 5 is a hollow round steel. The flip plate 3 is embedded in the hollow round steel along the axis of the hollow round steel and is welded and fixed. When the hollow round steel rotates, it can drive the flip plate 3 to flip. It is important to ensure that the flipping angle is around 60° to avoid the "dead point" caused by the flipping angle being too large. (The "dead point" is explained as the jamming phenomenon in the cam-linkage structure, when the angle of movement between the cam and the link is close to 0° or 180°, the front telescopic push rod 4 cannot extend or retract normally due to the friction and other resistance factors at the hinge. The terminal flipping shaft 5 cannot flip normally.)
[0027] Combination Figure 3 , Figure 4 , Figure 5 As shown, one end of the flip shaft 5 extends out of the chute and is connected to the telescopic push rod 4 via the cam assembly 6. The flip shaft 5 is a hollow round steel. The length of the hollow round steel is 30cm longer than the width of the chute. The upper part of the hollow round steel is slotted, and the flip plate 3 is embedded in the slot and then welded for reinforcement. The two ends of the hollow round steel extend out of the chute and are installed in the bearing seat 7. The bearing seat 7 is welded to the side wall of the chute.
[0028] The cam assembly 6 includes a first cam 61 and a second cam 62. The upper end of the first cam 61 is hinged to the lower end of the telescopic rod of the telescopic push rod 4, and the lower end of the first cam 61 is hinged to the upper end of the second cam 62. The lower end of the second cam 62 is fixedly connected to one end of the flipping shaft 5. When the telescopic push rod 4 is in the retracted state, the axes of the first cam 61 and the second cam 62 form an obtuse angle. When the telescopic push rod 4 is in the extended state, the axes of the first cam 61 and the second cam 62 form an acute angle. The hinge joints of the first cam 61 and the second cam 62 are both hinged using cylindrical pins 9.
[0029] The telescopic push rod 4 is a hydraulically driven hydraulic telescopic rod. The telescopic push rod 4 is arranged along the extension direction of the first channel 1 and is fixedly connected to the outer wall of the chute through the push rod base 8. The push rod base 8 is welded to the outer wall of the chute.
[0030] When the telescopic push rod 4 extends, it can cause the flip shaft 5 to rotate, which in turn causes the flip plate 3 to rotate counterclockwise. When the telescopic push rod 4 retracts, it can cause the flip shaft 5 to rotate, which in turn causes the flip plate 3 to rotate clockwise.
[0031] Combination Figures 1-5 As shown, during use, when it is necessary to open the first barrier 1 and block the second barrier 2 using the flap 3, in combination with... Figure 3 , Figure 4 As shown, the telescopic rod of the control telescopic push rod 4 extends, the upper end of the first cam 61 is pressured by the telescopic push rod 4, and the lower end of the second cam 62 is fixedly connected to the flipping shaft 5. The first cam 61 and the second cam 62 form an obtuse angle. The lower end of the first cam 61 and the upper end of the second cam 62 escape to one side, and the lower end of the second cam 62 rotates counterclockwise, thereby driving the flip plate 3 to rotate counterclockwise. At this time, the flip plate 3 is like... Figure 2 , Figure 5 As shown.
[0032] When it is necessary to open the second barrier 2 and block the first barrier 1 using flap 3, combined with Figure 3 , Figure 5 As shown, when the telescopic push rod 4 retracts, the upper end of the first cam 61 is pulled by the telescopic push rod 4, and the lower end of the second cam 62 is fixedly connected to the flipping shaft 5. The first cam 61 and the second cam 62 form an acute angle. When the first cam 61 and the second cam 62 are pulled up, the lower end of the second cam 62 rotates clockwise, thereby driving the flip plate 3 to rotate clockwise. At this time, the flip plate 3 is as follows: Figure 1 , Figure 4 As shown.
[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
