An impeller shaft is installed inside the material conveying channel of the impeller body, and several impeller frames are evenly installed around the impeller shaft. Impeller blades are disposed within the impeller frames, sliding inside and outside the frames. This device avoids replacing the entire impeller, reducing maintenance difficulty and repair costs. However, this type of device does not have a sealed design for the feeding structure of the impeller feeder. Therefore, the feeding structure is prone to leakage from the top of the feeder due to poor sealing performance, causing material loss and environmental pollution. Furthermore, it allows outside air to enter, affecting the stability of the process and product quality. Utility Model Content

[0004] The purpose of this invention is to provide an elastic sealing structure for an impeller feeder, in order to solve the problem that such devices do not have a sealing design for the feeding structure of the impeller feeder, which makes the feeding structure of the impeller feeder prone to leakage from the top of the feeder due to poor sealing performance, resulting in material loss and environmental pollution, and allowing outside air to enter, affecting the stability of the process and product quality.

[0005] To achieve the above objectives, an elastic sealing structure for an impeller feeder is provided, including a wheel, a sliding frame fixed to the top of the wheel, a feeding frame on the top of the sliding frame, a top fixed to the top of the feeding frame, a sealing cover between the sliding frame and the feeding frame, side frames fixed to the left and right ends of the sliding frame, a snap-fit ​​groove penetrating the upper end of the side frames, inner patches fixed to the left and right ends of the sealing cover, snap-fit ​​blocks fixed to the outside of the inner patches, and outer patches fixed to the upper and lower ends of the snap-fit ​​groove, with the inner sides of the two outer patches abutting against the outer sides of the snap-fit ​​blocks.

[0006] According to the elastic sealing structure of the impeller feeder, a sealing layer is fixed on the inner side of the sealing outer cover, and the inner side of the sealing layer is fixedly connected to the outer side of the feeding frame.

[0007] According to the elastic sealing structure of the impeller feeder, vibration motors are fixed at both the left and right ends of the feed frame, and the output ends of the two vibration motors extend into the inside of the feed frame.

[0008] According to the elastic sealing structure of the impeller feeder, threaded holes are passed through the center of the outer side of both side frames, and the threaded holes extend to the inner side of the snap-fit ​​block.

[0009] According to the elastic sealing structure of the impeller feeder, the feed frame is generally trapezoidal.

[0010] According to the elastic sealing structure of the impeller feeder, protective grooves are arrayed around the top surface of the sealing layer, and multiple protective grooves are obliquely opened.

[0011] According to the elastic sealing structure of the impeller feeder, the inner patch and the two outer patches are all elastically arranged.

[0012] According to the elastic sealing structure of the impeller feeder, two supporting arc frames are fixed at the bottom outer side of the impeller, and a supporting cross plate is fixed between the two supporting arc frames.

[0013] The above solution has the following beneficial effects: In order to enhance the sealing effect between the sliding frame and the feeding frame, a sealing outer cover is set between the sliding frame and the feeding frame, and side frames are fixed at both ends of the sliding frame. By attaching the inner patches with snap-fit ​​blocks at both ends of the outer sealing outer cover to the snap-fit ​​grooves that pass through the upper end of the side frames, and by screwing in reinforcing bolts into the threaded holes, the side frames and snap-fit ​​blocks are stably connected.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 The present invention discloses an elastic sealing structure for an impeller feeder, comprising a wheel 1, a sliding frame 2 fixed to the top of the wheel 1, a feeding frame 3 on the top of the sliding frame 2, a top 4 fixed to the top of the feeding frame 3, a sealing cover 5 between the sliding frame 2 and the feeding frame 3, side frames 6 fixed to the left and right ends of the sliding frame 2, a snap-fit ​​groove 7 penetrating the upper end of the side frames 6, inner patches 8 fixed to the left and right ends of the sealing cover 5, snap-fit ​​blocks 9 fixed to the outside of the inner patches 8, and outer patches 10 fixed to the upper and lower ends of the inner side of the snap-fit ​​groove 7, with the inner sides of the two outer patches 10 abutting against the outer side of the snap-fit ​​block 9. In the prior art, such devices do not have a sealing design for the feeding structure of the impeller feeder, thus the feeding structure of the impeller feeder is prone to sealing failure due to lack of sealing. Poor sealing performance can lead to material leakage from the top of the feeder, causing material loss and environmental pollution. It can also allow outside air to enter, affecting the stability of the process and product quality. To address this issue, a sealing cover 5 can be installed between the sliding frame 2 and the feeding frame 3. Side frames 6 are fixed to both ends of the sliding frame 2. The inner patches 8 with snap-fit ​​blocks 9 on the left and right ends of the sealing cover 5 are snapped into the snap-fit ​​groove 7 that runs through the upper part of the side frame 6. Reinforcing bolts are screwed into the threaded holes 13 to ensure a stable connection between the side frame 6 and the snap-fit ​​blocks 9. At this time, the inner patches 8 and the two outer patches 10 enhance the sealing effect of the snap-fit ​​blocks 9, thereby achieving a stable sealing effect for the sealing cover 5.

[0024] A sealing layer 11 is fixed inside the sealing outer cover 5. The inner side of the sealing layer 11 is fixedly connected to the outer side of the feeding frame 3. By setting the sealing layer 11, the connection performance between the inner side of the sealing outer cover 5 and the outer side of the feeding frame 3 is enhanced, thereby maintaining the sealing effect of the outer side of the feeding frame 3 and avoiding material loss and environmental pollution.

[0025] Vibration motors 12 are fixed at both the left and right ends of the feed frame 3. The output ends of the two vibration motors 12 extend through the inside of the feed frame 3. By setting the vibration motors 12, the material at both ends of the inner wall of the feed frame 3 can be shaken off, improving the material sliding effect. Threaded holes 13 are passed through the center of the outer side of the two side frames 6. The threaded holes 13 extend through the inside of the snap-fit ​​blocks 9, achieving the effect of fixing the two snap-fit ​​blocks 9.

[0026] The feeding frame 3 is trapezoidal in shape, which facilitates the material to slide down. The top surface of the sealing layer 11 is provided with protective grooves 14 arranged in an array around the perimeter. The multiple protective grooves 14 are all obliquely opened, which can improve the strength of the connection structure and improve the sealing performance.

[0027] The inner patch 8 and the two outer patches 10 are all elastically set to enhance the elastic effect of the inner patch 8 and the two outer patches 10. Two support arc frames 15 are fixed to the bottom outer side of the wheel 1, and a support cross plate 16 is fixed between the two support arc frames 15 to achieve the effect of supporting and reinforcing the bottom outer side of the wheel 1.

[0028] Working principle: First, the material is poured from the top 4 into the feeding frame 3, and then slides from the sliding frame 2 into the inner side of the wheel 1. The control system conveys the material. During the material's descent, the vibrating motor 12 shakes the material from both ends of the inner wall of the feeding frame 3, improving the descent effect. To enhance the sealing effect between the sliding frame 2 and the feeding frame 3, a sealing cover 5 is installed between them. Side frames 6 are fixed to both the left and right ends of the sliding frame 2. The inner patches 8 on both sides of the outer sealing cover 5, along with the snap-fit ​​blocks 9, are snapped into the inner side of the snap-fit ​​groove 7 that runs through the upper part of the outer side frame 6. Reinforcing bolts are screwed into the threaded holes 13 to ensure a stable connection between the side frame 6 and the snap-fit ​​blocks 9. At this time, the inner patches 8 and the two outer patches 10 enhance the sealing effect of the snap-fit ​​blocks 9, and a sealing layer 11 is set to enhance the connection performance between the inner side of the sealing cover 5 and the outer side of the feed frame 3, thereby maintaining the sealing effect of the outer side of the feed frame 3 and avoiding material loss and environmental pollution.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
