[0003] In the prior art, the feeding device is generally provided with a solenoid valve and a metering component to help complete the metering and packaging tasks, and the feeding process mainly relies on the gravity of the feed itself to complete the infusion. Sometimes, in order to avoid the blockage of the feed, an anti-blocking mechanism is arranged in the feeding pipe. The anti-blocking mechanism in the prior art mostly uses the stirring blade of the stirring mechanism as the dredging component. Although the stirring blade can complete the feed dredging work, the stirring blade is large in size and will inevitably affect the flow effect of the feed during the normal falling process of the feed. Utility Model Content

DETAILED DESCRIPTION

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0025] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The present invention provides a feed discharging device with an anti-blocking structure. Figures 1-6 As shown, the feed discharging device with an anti-blocking structure is applied to the discharge port of the silo 100, comprising: a discharge pipe 200 and an anti-blocking mechanism 300 provided inside the discharge pipe 200; the discharge pipe 200 is arranged at the discharge port of the silo 100. Under normal circumstances, when the control valve provided on the discharge pipe 200 away from the silo 100 is opened, the feed in the silo 100 will leave the silo 100 along the discharge pipe 200;

[0027] The anti-blocking mechanism 300 includes a central shaft seat 330, a transmission shaft 350, and a stirring shaft 320. The outer wall of the stirring shaft 320 is provided with a plurality of flexible chains 323. The stirring shaft 320 and the transmission shaft 350 are meshed and connected via a bevel gear structure. The side wall of the discharge pipe 200 is also provided with a motor 400. The transmission shaft 350 passes through the side wall of the discharge pipe 200 and is connected to the power output shaft of the motor 400.

[0028] When feed is blocked in the feed discharge pipe 200, the motor 400 drives the stirring shaft 320 to rotate via the transmission shaft 350. The flexible chain 323 located on the side of the stirring shaft 320 will spread to the surrounding area under the centrifugal force during the rotation of the stirring shaft 320, and finally break up the feed blocked in the feed discharge pipe 200, thereby completing the feed delivery operation.

[0029] In the present application, the flexible chain 323 generally adopts an ordinary chain structure. When it is not rotating, the chain will be attached to the outer wall of the stirring shaft 320 due to the scouring of the feed flow and the effect of its own weight. When blockage occurs, the feed stops flowing. After the stirring shaft 320 rotates, the flexible chain 323 will first produce a friction pushing effect on the feed near the stirring shaft 320 and increase the space near the stirring shaft 320. With the expansion of the space and the action of centrifugal force, the flexible chain 323 continues to erode the feed around the stirring shaft 320 and continues to expand the rotation range. At this time, the feed in the discharge pipe 200 will flow again due to the space below, until the flexible chain 323 is completely diffused under the action of centrifugal force. The rotation of the flexible chain 323 is used to break up all the blocked feed, allowing the feed in the discharge pipe 200 to resume flowing, and the anti-blocking mechanism 300 stops moving at this time.

[0030] In the present application, during the normal feed discharge process, the feed is discharged by its own weight. When the feed discharge is blocked, the flexible chain 323 is used as a stirring blade to stir the feed to clear the discharge pipe 200. During the normal feed discharge process, the flexible chain 323 will be attached to the outer wall of the stirring shaft 320 due to the flow of feed and the effect of its own weight. This can reduce the interference of the flexible chain 323 on the discharge pipe 200 during the normal feed discharge process and improve the flow efficiency of the feed during the normal feed discharge process.

[0031] As a preferred implementation in this embodiment, the anti-blocking mechanism 300 further includes an outer ring frame 310; the outer ring frame 310 is connected to the inner wall of the discharge pipe 200, the central shaft seat 330 is located at the center of the outer ring frame 310, and the outer ring frame 310 and the central shaft seat 330 are connected by at least two groups of connecting rods;

[0032] The central shaft seat 330 includes an upper shaft seat 331 and a lower shaft seat 332. The upper shaft seat 331 is formed into a conical or truncated cone structure at one end away from the lower shaft seat 332 to prevent the upper shaft seat 331 from affecting the feed flow rate. The side wall of the lower shaft seat 332 is provided with a connecting hole, and one end of the transmission shaft 350 extends from the connecting hole to the interior of the lower shaft seat 332.

[0033] An outer protective tube 340 is further provided between the lower shaft seat 332 and the discharge pipe 200. The outer protective tube 340 is nested outside the transmission shaft 350 located between the lower shaft seat 332 and the discharge pipe 200. The transmission shaft 350 extends out of the discharge pipe 200 at one end away from the central shaft seat 330 and is connected to the motor 400.

[0034] The stirring shaft 320 includes an upper shaft 321, a lower shaft 322 and a driven wheel 324. The driven wheel 324 is arranged at the connection between the upper shaft 321 and the lower shaft 322. It can also be seen that the driven wheel 324 divides the stirring shaft 320 into the upper shaft 321 and the lower shaft 322. The upper shaft 321 extends from the center of the upper shaft seat 331 to form a central shaft seat 330, and the lower shaft 322 extends from the lower shaft seat 332 to form a central shaft seat 330.

[0035] The portion of the upper shaft 321 extending from the central shaft seat 330 and the portion of the lower shaft 322 extending from the central shaft seat 330 are both provided with a plurality of sets of flexible chains 323, and each set of flexible chains 323 is provided at a different height position of the upper shaft 321 and the lower shaft 322;

[0036] As a preferred implementation in this embodiment, the driven wheel 324 is a bevel gear structure, and the transmission shaft 350 extends to the end inside the lower shaft seat 332 and is provided with a driving wheel adapted to the driven wheel 324. The driving wheel is also a bevel gear. The driven wheel 324 and the driving wheel are meshed and connected, and the power of the motor 400 is transmitted to the stirring shaft 320 through the cooperation of the driven wheel 324 and the driving wheel.
