Description

Technical Field

[0001] This utility model relates to the field of rotary chain feeders, and in particular to an anti-clogging structure for rotary chain feeders. Background Technology

[0002] The existing chain plate feeder is a subclass of the rotary chain feeder. It realizes material conveying through the chain-chain plate rotation system. The main components of the chain plate feeder are usually composed of a base, drive chain, chain plate and drive motor. It is widely used in mining, cement, metallurgy and other industries, and can quickly feed and transport materials such as ore.

[0003] During use, since the size of the ore after mining is usually different, during the transportation process by the feeder, the ore of different sizes is guided to the surface of the feeder's chain plate through the feeding frame. At this time, the ore of different sizes intersects, and the smaller ore will fill the gaps, resulting in the ore accumulating together, which can easily cause outlet blockage and prevent subsequent processing from being carried out. Utility Model Content

[0004] In view of the problem that blockage may occur at the outlet when ores of different sizes are simultaneously conveyed by a feeder in the above-mentioned or existing technologies, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: It includes an anti-blocking component comprising two screening plates, both of which are slidably connected to the inner wall of a feeding frame for feeding ore. A feeder body for feeding and transporting the ore is located on the lower side of the feeding frame. The feeding frame is fixedly connected to the feeder body. Drive components for adjusting the position of the screening plates are located on both sides of the feeding frame and the feeder body. A buffer component is located on the inner wall of the feeding frame for further protection of the screening plates. A crushing component includes a crushing component fixedly connected to the side of the feeding frame near the feeder body. The crushing component is used to crush ore larger than the opening of the screening plates.

[0006] As a preferred embodiment of the anti-clogging structure of the chain feeder of this utility model, the drive assembly includes two rotating wheels, which are respectively fixedly connected to both ends of the drive shaft inside the feeder body. Drive frames are slidably connected to the surfaces of both rotating wheels. Multiple rods are fixedly connected to the upper sides of both drive frames. Two connecting frames are fixedly connected to the arc surfaces of the multiple rods. The connecting frames are slidably connected to the side walls of the feeding frame. Springs are sleeved on the surfaces of the multiple rods, and both ends of the springs are fixedly connected to the multiple rods. Limit frames are fixedly connected to both sides of the feeding frame, and the multiple rods are slidably connected to the inner walls of the limit frames.

[0007] As a preferred embodiment of the anti-blocking structure of the conveyor feeder of this utility model, the buffer assembly includes two square frames fixedly connected to the inner wall of the feeding frame, and rubber balls are fixedly connected to the four corners of the two square frames.

[0008] As a preferred embodiment of the anti-clogging structure of the conveyor belt feeder of this utility model, both screening plates are slidably connected to the inner wall of the feeding frame, and the two screening plates are placed mirror images of each other on the inner wall of the feeding frame and the screening plates are placed at an angle.

[0009] As a preferred embodiment of the anti-clogging structure of the rotating chain feeder of this utility model, the crushing component includes a connecting frame fixedly connected to the side of the feeding frame near the main body of the feeder. Two crushing rollers are rotatably connected to the inner wall of the connecting frame. Two gears are fixedly connected to both sides of the connecting frame. Each of the two gears is fixedly connected to one end of the crushing roller. A drive wheel is fixedly connected to the surface of the gear. A transmission belt is provided on the surface of both the rotating wheel and the drive wheel. Two openings are opened on the side of the feeding frame near the connecting frame.

[0010] As a preferred embodiment of the anti-clogging structure of the chain feeder of this utility model, the two crushing rollers are connected to the inner wall of the connecting frame in an up-down distributed rotational manner, and the two crushing rollers are tilted to the right.

[0011] As a preferred embodiment of the anti-clogging structure of the conveyor belt feeder of this utility model, the sides of the two screening plates near the opening are parallel to the bottom edge of the opening.

[0012] The beneficial effects of the anti-clogging structure for a rotary chain feeder of this utility model are as follows: 1. By using the anti-blocking component, the drive assembly drives the screening plate to move up and down repeatedly on the inner wall of the feeding frame. This helps the workers guide smaller ore to the surface of the feeder body, thus preventing the feeding frame opening from getting blocked. This ensures that the feeder body can transport ore for a long time without blockage, which would affect the conveying efficiency. 2. The crushing component and drive component help larger ore enter the inner wall of the connecting frame, and the crushing effect is achieved by two relatively rotating crushing rollers. This achieves the effect of crushing the ore, so that larger ore does not need to be discharged separately. It can be crushed during the operation of the anti-blocking component, and the crushed ore can be re-entered into the interior of the feeding frame for conveying. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example 1, referring to Figures 1-4This is the first embodiment of the present invention. This embodiment provides an anti-clogging structure for a rotary feeder, which can achieve the effect of preventing clogging when screening ores of different sizes placed on the inner wall of the feeding frame. It includes an anti-clogging component, including two screening plates 10, both of which are slidably connected to the inner wall of the feeding frame 11 for feeding ores. The lower side of the feeding frame 11 is provided with a feeder body 12 for feeding and transporting ores. The feeding frame 11 and the feeder body 12 are fixedly connected. Both sides of the feeding frame 11 and the feeder body 12 are provided with drive components 13 for adjusting the position of the screening plates 10. The inner wall of the feeding frame 11 is provided with a buffer component 14 for further protecting the screening plates 10. The crushing component includes a crushing component 20 fixedly connected to the side of the feeding frame 11 near the feeder body 12. The crushing component 20 is used to crush ores larger than the opening 206 of the screening plate 10.

[0021] Specifically, through the cooperation of the drive assembly 13 on the upper side of the feeder body 12 and the screening plate 10, the ore on the inner wall of the feeding frame 11 can be screened by size. The ore that can be directly put into use falls directly into the chain plate position of the feeder body 12 through the screening plate 10, thereby realizing transportation. At the same time, the buffer assembly 14 on the inner wall of the feeding frame 11 can play a buffering and protective role when the ore falls onto the surface of the screening plate 10, thus extending the service life of the screening plate 10. Meanwhile, the larger ore that is blocked by the screening will enter the interior of the crushing assembly 20, be crushed by the crushing assembly 20, and then flow into the inner wall of the feeding frame 11 for re-feeding.

[0022] Furthermore, the drive assembly 13 includes two rotating wheels 131, which are fixedly connected to both ends of the drive shaft inside the feeder body 12. Drive frames 132 are slidably connected to the surfaces of both rotating wheels 131. Multi-section rods 133 are fixedly connected to the upper sides of both drive frames 132. Two connecting frames 134 are fixedly connected to the arc surfaces of the multi-section rods 133. The connecting frames 134 are slidably connected to the side walls of the feeding frame 11. Springs 135 are sleeved on the surfaces of the multi-section rods 133, and both ends of the springs 135 are fixedly connected to the multi-section rods 133. Limiting frames 136 are fixedly connected to both sides of the feeding frame 11, and the multi-section rods 133 are slidably connected to the inner walls of the limiting frames 136. The buffer assembly 14 includes two square frames 141 fixedly connected to the inner wall of the feeding frame 11. Rubber balls 142 are fixedly connected to the four corners of the two square frames 141.

[0023] When the feeder body 12 is working, the drive motor and drive chain on its surface drive the chain plate on the surface to achieve transmission. At this time, the internal drive shaft will be driven by the drive chain to rotate. When the drive shaft rotates, it can help the drive frame 132 drive the multi-section rod 133 to rotate, and then cooperate with the connecting frame 134 to drive the two screening plates 10 to achieve the effect of sliding up and down. This allows the ore of the appropriate size to fall directly onto the surface of the feeder body 12. When the screening plate 10 slides down under the pressure of the ore, it will impact the surface of the rubber ball 142. At the same time, the rubber ball 142 plays a buffering role, reducing the impact damage, thereby improving the service life of the screening plate 10 to a certain extent.

[0024] Preferably, both screening plates 10 are slidably connected to the inner wall of the feeding frame 11, and the two screening plates 10 are placed mirror images of each other on the inner wall of the feeding frame 11 and the screening plates 10 are placed at an angle.

[0025] It should be noted that since the screening plate 10 is placed at an angle, when the ore is on the surface, it can help the ore roll to one side. At the same time, in conjunction with the up-and-down movement effect generated by the drive component 13, it can improve the screening effect and better help the ore pass through the screening plate 10.

[0026] During use, the operator starts the feeder body 12, enabling the internal chain plate to perform transmission operation. Simultaneously, the ore is transported to the upper surface of the feeding frame 11 via external equipment. The feeding frame 11 then conveys the ore to the higher side of the screening plate 10, thus initiating the screening of ore size. When the screening plate 10 is impacted, it presses against the square frame 141. The rubber balls 142 on the surface of the square frame 141 provide a buffering effect against the impact, thereby reducing the impact force of ore falling onto the surface of the screening plate 10. The springs 135 on the surface of the multi-section rod 133 further buffer the impact force on the screening plate 10, the drive frame 132, and the multi-section rod 133, thereby improving the service life of the components. When the roller 131 rotates, it drives the multi-section rod 133 to move up and down through the drive frame 132, causing the screening plate 10 to move up and down on the inner wall of the feeding frame 11, effectively screening the ore size without causing blockage.

[0027] Example 2, refer to Figures 1-3This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a crushing component for the anti-blocking structure of the conveyor feeder based on embodiment 1. This solves the problem that larger ores cannot be quickly put into use after being blocked by the screening plate 10. It includes a crushing component 20, which includes a connecting frame 201 fixedly connected to the side of the feeding frame 11 near the feeder body 12. Two crushing rollers 202 are rotatably connected to the inner wall of the connecting frame 201. Two gears 203 are fixedly connected to both sides of the connecting frame 201. Both gears 203 are fixedly connected to one end of the crushing rollers 202. A drive wheel 204 is fixedly connected to the surface of the gears 203. The surfaces of the rotating wheel 131 and the drive wheel 204 are provided with a transmission belt 205. Two openings 206 are opened on the side of the feeding frame 11 near the connecting frame 201.

[0028] Specifically, when larger ore is on the surface of the screening plate 10, since the screening plate 10 is placed at an incline, the ore can roll into the inner wall of the connecting frame 201. The two gears 203 driven by the transmission belt 205 will drive the two crushing rollers 202 to rotate relative to each other, thereby crushing the ore, and then it will enter the screening plate 10 on the inner wall of the feeding frame 11 again through the inclined surface below.

[0029] Furthermore, the two crushing rollers 202 are rotatably connected to the inner wall of the connecting frame 201 in an up-down distributed manner, and the two crushing rollers 202 are tilted to the right. The sides of the two screening plates 10 near the opening 206 are parallel to the bottom edge of the opening 206.

[0030] It should be noted that, due to the left-high-right-low placement of the crushing roller 202, the ore, after entering the inner wall of the connecting frame 201, will not impact the feeding frame 11 due to the pressure generated by the rotation crushing, thus facilitating the crushing operation. At the same time, when the side of the screening plate 10 is lower than the bottom edge of the opening 206, smaller ore will be blocked and will not enter the inner wall of the connecting frame 201, but will fall directly onto the surface of the feeder body 12 for transportation, thus facilitating the transportation and use of the ore.

[0031] During use, the ore falls onto the surface of the screening plate 10. At this time, the screening plate 10 is under pressure. The side of the screening plate 10 near the opening 206 is lower than the bottom of the opening 206. As a result, smaller ore will not enter the connecting frame 201, while larger ore rolls into the inner wall of the connecting frame 201. Because the two crushing rollers 202 are positioned with the left side higher than the right side, the ore can tilt to the right. As a result, when the ore splashes, it will not impact the inner wall of the feeding frame 11. The two crushing rollers 202 achieve relative rotation through the gears 203 on both sides. The left gear 203 achieves rotation through the drive belt 205 on the surface of the rotating wheel 131 and the drive wheel 204, thereby driving the right gear 203 to rotate in the direction of the left gear 203, thus achieving the crushing effect. The crushed ore then enters the lower side of the screening plate 10 on the inner wall of the feeding frame 11 for feeding.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
