[0026] Example 1

[0027] See also Figure 1, an embodiment of the present utility model provides a wet mud feeding hopper for a wet mud drying device, which includes a feeding component and a supporting component. The feeding component is supported by the supporting component, and forms a feeding inclination according to the set position and height relationship of the supporting component. The supporting component includes a first supporting part 21 and a second supporting part 22. The first supporting part 21 and the second supporting part 22 are arranged at intervals, and the heights of the first supporting part 21 and the second supporting part 22 are one high and one low, forming an inclined positional relationship therebetween, so that the material is transported from a lower place to a higher place. Generally, the drying device dries inside a drying chamber, and it is necessary to connect the end of the feeding hopper to the drying device so that the feeding is directly completed after the feeding. First limiting side plates 23 and second limiting side plates 24 are respectively arranged on both sides of the first supporting part 21 and the second supporting part 22. Through the arrangement of the first limiting side plates 23 and the second limiting side plates 24, the initial prototype of the feeding trough is formed. By restricting both sides through the first limiting side plates 23 and the second limiting side plates 24, the wet mud will not flow out everywhere, enabling the wet mud to complete normal feeding.

[0028] Please refer to Figure 3 , the set height of the first supporting part 21 is lower than the set height of the second supporting part 22. The position of the first supporting part 21 is one end of the feeding, and the second supporting part 22 is the discharging end. Bearing seats 25 are respectively arranged on both sides of the tops of the first supporting part 21 and the second supporting part 22. A first driving roller 26 and a second driving roller 27 are respectively arranged in the bearing seats 25 on both sides of the first supporting part 21 and the second supporting part 22. The feeding belt 11 feeds through the first driving roller 26 and the second driving roller 27. The feeding belt 11 wraps the first driving roller 26 and the second driving roller 27. When the first driving roller 26 and the second driving roller 27 rotate, the feeding belt 11 simultaneously performs the feeding work. The feeding component includes the feeding belt 11 and a plurality of feeding bins 12 arranged at intervals on the feeding belt 11. An accommodating cavity is arranged inside the feeding bin 12. The accommodating cavity of the feeding bin 12 is arranged in a closed manner. The feeding bin 12 is the part for accommodating wet mud, and there are relatively dry and moisture-heavy wet muds. When encountering moisture-heavy wet mud, the closed feeding bin 12 will store the wet mud inside to prevent it from overflowing. If conventional belt conveying is used, only relatively dry wet mud can be output, and for moisture-heavy wet mud, it will flow down along the feeding belt 11 and return to the storage bin 31, resulting in difficult feeding. By setting a closed feeding bin 12, wet mud in any state can be conveyed without difference.

[0029] Please refer to Figure 1, both ends of the feeding belt 11 are respectively sleeved on the first driving roller 26 and the second driving roller 27. A plurality of auxiliary driving rollers 28 are arranged at intervals between the first limiting side plate 23 and the second limiting side plate 24; the plurality of auxiliary driving rollers 28 are all in contact with the inner wall of the feeding belt 11. If only the first driving roller 26 and the second driving roller 27 are provided, the feeding action can be completed, but when it is transported to the middle, it will sag downward due to its own gravity factor, resulting in slow feeding. Therefore, a plurality of auxiliary driving rollers 28 are adopted, so that the feeding belt 11 is always in contact with the auxiliary driving rollers 28 during feeding, so that it obtains an auxiliary support. The feeding belt 11 will not sag due to gravity, so that the feeding process can proceed smoothly.

[0030] Embodiment 2

[0031] Please refer to Figure 1 , the embodiment of the present utility model provides a wet mud hopper for a wet mud drying device, and the feeding belt 11 is inclined by the inconsistent heights of the first support portion 21 and the second support portion 22; this inclination angle can be adjusted according to the actual position. It is adaptively set according to the feeding position, the position of the drying device, and the height of the feeding port 33 of the drying device. It makes the feeding simple and fast, and can complete the feeding at one time.

[0032] Please refer to Figure 3 , a storage bin 31 is provided at the lower end of the support assembly where the feeding belt 11 is located. When the wet mud is transported to the hopper, it is stored in the storage bin 31. The feeding belt 11 circulates to obtain the materials in the storage bin 31 and circulates for feeding, without the need to repeat the feeding work. An auxiliary discharge bin 41 is provided at the higher end of the support assembly where the feeding belt 11 is located. When the wet mud is input and output, it needs to be restricted, otherwise the wet mud will splash everywhere. By providing the auxiliary storage bin 31, the wet mud can only splash in the auxiliary storage bin 31, and through the auxiliary storage bin 31, the wet mud directly enters the inside of the drying device for drying, and there will be no problem of failed wet mud feeding.

[0033] Preferably, the storage bin 31 is hollow inside and is provided with a storage cavity 32; an inlet 33 is provided at the top of the storage cavity 32 inside the storage bin 31, and the inlet 33 is completely open. The open setting of the inlet 33 makes the area for receiving materials larger, making it easier for the materials to enter the storage bin 31, and will not fall outside the inlet 33 due to the problem of the inlet 33, resulting in a poor working environment.

[0034] Preferably, a feeding port 34 is provided at the connection between the storage bin 31 and the feeding bin 12 of the feeding belt 11; first and second material limiting plates 35 and 36 are provided on both sides of the feeding port 34; the first and second material limiting plates 35 and 36 limit the feeding port 34 within the range of the feeding belt 11. A number of feeding bins 12 are provided on the feeding belt 11 to perform a cyclic feeding and discharging operation. Through the open feeding port 34, the feeding bin 12 can more easily obtain the wet mud inside the storage cavity 32. The feeding bin 12 is arranged in a blade shape, which can more easily cut into the material. When the material agglomerates, it is not easy to feed it. Through the blade-shaped arrangement, the agglomerated material is cut, making it easier to complete the feeding. The first and second material limiting plates 35 and 36 can also limit the material that falls out due to vibration. During feeding, the material in the feeding bin 12 may be shaken out due to vibration. After being shaken out, it will be limited by the first and second material limiting plates 35 and 36 and fall into the next feeding bin 12 or into the recovery tank 30 on the following recovery plate 29 for recovery.

[0035] Please refer to Figure 1 and Figure 2 , preferably, the inner cavity of the feeding bin 12 is arranged in a "V" shape or a "U" shape. After the inner cavity of the feeding bin 12 is arranged in a "V" shape or a "U" shape, it can more easily accommodate the material. Especially when using a "V" - shaped inner cavity, both inner walls of the "V" - shaped inner cavity are inclined planes, which are more convenient for feeding and discharging. Through the inclined planes, it is easier to cut into the material, and it is not easy to accumulate inside during discharging.

[0036] Preferably, baffles 13 are provided on both sides of the feeding bin 12 with the inner cavity being in the "V" shape or the "U" shape; the baffles 13 and the "V" - shaped or "U" - shaped inner cavity form the accommodating cavity of the feeding bin 12. The baffles 13 are used to completely enclose the positions of the feeding bin 12 except the opening, so that the wet mud can be transported and it is not difficult to transport due to the relatively high moisture content of the wet mud.

[0037] Please refer to Figure 2, on one side of the storage bin 31, there is a driving motor 42, and the driving motor 42 is arranged through a receiving box body 43; the output shaft 44 of the driving motor 42 is connected to the first driving roller 26. The conveying driving motor 42 drives the overall equipment, drives the first driving roller 26 to rotate, and through the contact relationship between the feeding belt 11 and the first driving roller 26 and the second driving roller 27, it completes a transportation work. The auxiliary driving roller 28 is movably arranged based on the first side plate and the second side plate, and the auxiliary driving roller 28 can rotate between the first side plate and the second side plate. The contact between the feeding belt 11 and the auxiliary driving roller 28 also drives the auxiliary feeding roller through friction of the feeding belt 11, thereby completing the feeding.

[0038] Please refer to Figure 3 , preferably, a recovery plate 29 is further provided at the bottom of the feeding belt 11; the recovery plate 29 is installed through the first support portion 21 and the second support portion 22. The recovery plate 29 recovers the wet mud that adheres in the feeding bin 12 and does not enter the drying device. When the wet mud does not enter the drying device during feeding and circulates in the feeding bin 12, it may fall off because the opening of the feeding bin 12 faces downward, and at this time, it will fall onto the recovery plate 29. The two ends of the recovery plate 29 are respectively connected to the higher end of the feeding belt 11 and the storage bin 31. The recovery plate 29 is provided with a recovery groove 30; the inner cavity of the recovery groove 30 is in a "V" shape or a "U" shape. The wet mud is recovered again through the "V" - shaped or "U" - shaped recovery groove 30 provided on the recovery plate 29, which not only protects the working environment but also enables the wet mud to be repeatedly conveyed.

[0039] Please refer to Figure 1 , the wet mud enters the storage cavity 32 of the conveying storage bin 31 through the conveying feed port 33 for stacking and storage. At this time, the driving motor 42 is started, and the driving motor 42 drives the first driving roller 26. Through the connection between the feeding belt 11 and the first driving roller 26 and the second driving roller 27, the feeding belt 11 starts to feed. The feeding bin 12 on the feeding belt 11 feeds the wet mud inside the storage cavity 32 through the feeding port 34. The wet mud is arranged in a closed - type except for the opening, so that the wet mud can be fed without difference. When it is fed to a preset position, the auxiliary discharge bin 41 assists the wet mud to be discharged, so that the wet mud can be conveyed into the drying device. Some wet mud adheres to the feeding bin 12 and does not discharge normally at the discharge port, but during the circulation process, the material will fall again because the feeding bin 12 faces downward at the opening. To avoid the dropped material from polluting the working environment, the recovery plate 29 is set, and by restricting the dropping position of the possible dropped wet mud inside the recovery plate 29, it makes the wet mud enter the storage cavity 32 again and wait for the next feeding.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
