[0048] Embodiment 1

[0049] Refer to Figures 1 to 4 , which is the first embodiment of the present utility model, and a uniform feeding device is proposed.

[0050] In this embodiment, the uniform feeding device includes a base frame 1, a feed bin 2, a feeding main body 31, a feeding shaft 33, feeding fan blades 34, a first driver 35, a discharging unit 4 and a vibration unit 5. The discharging unit 4 includes a discharging cylinder 41, a discharging shaft 43, a second driver 44 and a pushing plate 45. The vibration unit 5 includes a vibration rod 51, a driving wheel 52, a third driver 53 and a spring 54. Further, a cushion block 55 is added. During operation, the materials are first stacked in the feed bin 2, and then the first driver 35 is started by an external controller. The first driver 35 selects a motor driven by electricity in the prior art. The power output by the first driver 35 drives the feeding shaft 33 and the feeding fan blades 34 in sequence. A material feeding space is formed between any two adjacent feeding fan blades 34. By means of the feeding shaft 33 and a plurality of feeding fan blades 34, a plurality of feeding spaces are formed. With the power output by the first driver 35, the stable and uniform rotation of the feeding shaft 33 and the feeding fan blades 34 is realized, and thus the uniform feeding of the materials is realized, which can effectively prevent the materials from accumulating at the bottom of the feed bin 2 and causing blockage. With the transfer of the materials by the feeding main body 31, the materials move from the feeding chamber 32 to the discharging chamber 42 of the discharging cylinder 41. At this time, with the help of the external controller, the second driver 44 is started. The second driver 44 selects a motor driven by electricity in the prior art. The power output after the second driver 44 is started is used to drive the discharging shaft 43 to rotate, and the discharging shaft 43 drives the pushing plate 45 to rotate synchronously. By means of the helically arranged pushing plate 45, the materials are conveyed from one end of the discharging chamber 42 to the other end and enter the next processing step.When the second driver 44 starts to work, the third driver 53 is started synchronously. The third driver 53 selects an electric motor in the prior art. The power output by the third driver 53 is used to drive the driving wheel 52 to rotate. The driving wheel 52 is preferably a cam, and the driving wheel 52 can also be an eccentric wheel. When the driving wheel 52 rotates, it will push and squeeze the vibrating rod 51 to slide on the base frame 1. The vibrating rod 51 gradually approaches the cushion block 55 and collides with the cushion block 55. By means of the collision between the vibrating rod 51 and the cushion block 55, a certain impact is formed on the materials in the discharge chamber, avoiding the materials from gradually adhering to the inner wall of the discharge chamber 42, causing material jamming, condensing into blocks after too long time, hindering the operation of the discharge shaft 43 and the pushing plate 45, and at the same time increasing the cleaning difficulty of the discharge cylinder 41. By means of the cushion block 55, it can buffer the direct collision between the vibrating rod 51 and the discharge cylinder 41, damage the discharge cylinder 41, and reduce the service life of the discharge cylinder 41. When the vibrating rod 51 slides towards the cushion block 55, the vibrating rod 51 will synchronously squeeze the spring 54, and the spring 54 will contract under force and accumulate elastic force. The rotation center of the driving wheel 52 is center A. As the driving wheel 52 rotates, when the vibrating rod 51 slides to the farthest distance from the center A, the driving wheel 52 continues to rotate. At this time, the spring 54 releases the accumulated elastic force. Under the pushing action of the spring 54, the vibrating rod 51 slides in the direction away from the cushion block 55, and at the same time ensures that the driving wheel 52 and the vibrating rod 51 are always in an extrusion contact state, making preparations for the next impact. By means of the spring 54 and the driving wheel 52, the vibrating rod 51 forms continuous reciprocating sliding, effectively avoiding the materials on the inner wall of the discharge cylinder 41 from condensing into blocks and increasing the workload of subsequent cleaning.

[0051] Embodiment 2

[0052] Refer to Figures 1 to 3 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is:

[0053] Compared with Embodiment 1, on the basis that the uniform feeding device includes a base frame 1, a feed bin 2, a feeding main body 31, a feeding shaft 33, a feeding fan blade 34, a first driver 35, a discharging unit 4 and a vibrating unit 5, a coupling member 61 and a coupling member 62 are further added. When the vibrating rod 51 forms an impact on the discharge cylinder 41, the discharge cylinder 41 will inevitably vibrate. Through the coupling member 61 and the coupling member 62, an active power transmission structure is formed between the second driver 44 and the discharge shaft 43, ensuring the stability of the power transmission of the second driver 44 and avoiding the instability of the power output of the second driver 44 when the discharge cylinder 41 and the discharge shaft 43 vibrate synchronously, and reducing the service life of the second driver 44.

[0054] Embodiment 3

[0055] Refer to Figures 1 to 3, which is the third embodiment of the present utility model. The difference between this embodiment and the first embodiment is as follows:

[0056] Compared with the first embodiment, on the basis that the uniform feeding device includes a base frame 1, a feed bin 2, a feeding main body 31, a feeding shaft 33, feeding fan blades 34 and a first driver 35, a material leveling unit 7 is further added. The material leveling unit 7 includes a dispersing member 71, dispersing bars 72, a wall scraping member 73 and a fourth driver 74. Before the material enters the feed bin 2, the fourth driver 74 is started through an external controller. The fourth driver 74 selects a motor driven by electricity in the prior art; after the fourth driver 74 is started, the power output drives the dispersing member 71 and the wall scraping member 73 to rotate simultaneously through a component capable of power transmission such as a chain or a belt. By means of the rotating dispersing member 71, the falling material is buffered and guided, so that the material diffuses to the periphery of the feed bin 2, avoiding the material from concentrating and falling to a certain place in the feed bin 2, which is not conducive to the uniform feeding of the feeding main body 31; at the same time, when the dispersing member 71 rotates, it will synchronously drive the arc-shaped dispersing bars 72, and the rotating dispersing bars 72 can guide the material; the rotating wall scraping member 73 can push the material at the inner walls around the feed bin 2, avoiding the formation of dead corners at the side walls around the feed bin 2, which is beneficial to ensuring the first-in, first-out of the material. At the same time, with the help of the wall scraping member 73, the material around the feed bin 2 can be collected towards the middle, facilitating the material to enter the feeding chamber 32 and ensuring the continuous and uniform feeding of the material.

Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
