Detailed implementation mode

[0023] In order to enable those skilled in the art of this technology to better understand the technical solutions in this utility model, the following will clearly and completely describe the technical solutions in the embodiments of this utility model with reference to the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0024] As Figure 1 and 2 shown, the feeding device 100 in an embodiment of this utility model includes a silo mechanism 10 and at least one discharging mechanism 20. The silo mechanism 10 includes a stirring bin 11. A paddle 111 is arranged in the stirring bin 11, and a stirring motor 112 for driving the paddle 111 to rotate is installed outside the stirring bin 11. An enclosure 113 is fixed at the opening of the stirring bin 11, which extends downward into the stirring bin 11 and forms a gap for the material to pass through between it and the paddle 111. The discharging mechanism 20 is connected to the stirring bin 11 and is arranged outside the paddle 111.

[0025] Since the enclosure 113 is arranged on the stirring bin 11, a gap is formed between the enclosure 113 and the paddle 111. Therefore, most of the materials are accumulated within the range surrounded by the enclosure 113. And the discharging mechanism 20 is arranged outside the paddle 111. Therefore, only part of the materials move towards the discharging mechanism 20 through the gap between the enclosure 113 and the paddle 111 during operation. Therefore, this setting method can prevent the situation of unsmooth discharging caused by the accumulation of materials at the inlet of the discharging mechanism 20.

[0026] It is easy to think that the gap between the enclosure 113 and the paddle 111 can be set to be adjustable, that is, the length of the enclosure 113 extending into the stirring bin 11 is adjustable. When dealing with materials of different properties and particle sizes, the discharging rate can be assisted to be controlled by adjusting the extension length of the enclosure 113.

[0027] Preferably, a storage bin 12 is fixed above the stirring bin 11. The storage bin 12 is fixed to the enclosure 113 or the stirring bin 11 to increase the amount of materials that can be stored and avoid frequent replenishment of materials during operation.

[0028] Further, the storage bin 12 can be provided with a door mechanism (not shown in the figure) that can be opened and closed at the bottom. Through this door structure, the amount of material falling into the mixing bin 11 at one time can be controlled, rather than simply increasing or expanding the storage space above the mixing bin 11, which has higher flexibility.

[0029] A cover plate 121 is provided at the top of the storage bin 12 to prevent foreign objects from falling into the storage bin 12 and to avoid possible dust flying outwards or the material being shaken out. The cover plate 121 is detachably fixed to the storage bin 12. The operator can pour the material into the storage bin 12 by opening the cover plate 121, or a feed inlet 122 that can be opened and closed can be provided on the cover plate 121, and the material can be poured into the storage bin 12 through the feed inlet 122. This embodiment is not limited.

[0030] In one embodiment, the storage bin 12 is detachably fixed to the enclosure 113 so that when an error occurs in the mixing bin 11, such as the material getting stuck or the paddle 111 malfunctioning and unable to rotate, the storage bin 12 can be detached for maintenance. Specifically, bolts or other detachable fixing methods can be used. This embodiment is not limited.

[0031] Preferably, the rotation range of the paddle 111 is circular. Therefore, the mixing bin 11 and the storage bin 12 can also be set as cylindrical bodies, or can also be set as rectangular bodies. This embodiment is not limited.

[0032] It is easy to think that to improve production efficiency, a plurality of feeding mechanisms 20 can be connected to the mixing bin 11 to perform multiple feeding operations simultaneously, that is, to fill materials into multiple bags at the same time. The plurality of feeding mechanisms 20 can be connected to the mixing bin 11 in an equidistant or non-equidistant manner. This embodiment is not limited.

[0033] As Figure 1 and 2 shown, the feeding mechanism 20 includes a feeding pipe 21, a feeding motor 22, and a screw conveyor (not shown in the figure). The feeding pipe 21 is fixed to the bottom of the mixing bin 11 and is connected to the mixing bin 11. The screw conveyor is arranged in the feeding pipe 21. The feeding motor 22 is fixed to the mixing bin 11, and it connects and drives the screw conveyor to rotate to drive the material to be conveyed downward in a spiral direction.

[0034] For convenient fixing, the outer diameter of the mixing bin 11 is larger than the outer diameter of the storage bin 12. Therefore, a blank area is formed at the top of the mixing bin 11 for installing and fixing the feeding motor 22.

[0035] Preferably, the unloading mechanism 20 also includes a cylinder 24, a guide rod 25 and a plug 26. The cylinder 24 is fixed on the outer wall of the conveying pipe 21, and the plug 26 is arranged at the unloading port at the end of the conveying pipe 21. The cylinder 24 is connected through the guide rod 25 and drives the plug 26 to move up and down. When moving upward, the plug 26 can cover the unloading port at the end of the conveying pipe 21 to prevent the material from falling. When moving downward, the unloading port of the conveying pipe 21 is opened to allow the material to fall.

[0036] Furthermore, the hole plug 26 can be set to a cone, which can be partially inserted into the end of the feed pipe 21 when it moves upward to form a ring-shaped discharge port at the end of the feed pipe 21, and the area of the discharge port can be adjusted with the fine-tuning of the hole plug 26, thereby controlling the discharge rate and keeping the discharge rate at a reasonable level to prevent it from being too fast or too slow.

[0037] Furthermore, to remove dust from the material, a filter (not shown) can be installed inside the conveying pipe. This filter is placed around the outer periphery of the screw conveyor. A hole is opened in the outer wall of the conveying pipe 21. An external negative pressure device is connected to create a pressure differential between the inside and outside of the conveying pipe 21, thereby adsorbing dust on the filter. When excessive dust accumulates on the filter, the negative pressure device reverses and back-blows the filter, removing the dust and restoring its adsorption function.

[0038] Secondly, a bag expansion tube can be provided on the feeding tube 21, which can blow or suck air into the bag to expand it before loading, or suck out excess air in the bag and then wrap it after loading, thereby improving the flexibility of the equipment.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0040] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
