Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically to an anti-clogging device for the discharge port of a feeding machine. Background Technology

[0002] Feeding machines are widely used in many fields such as aquaculture and industrial production to deliver materials to designated locations. However, in actual use, the discharge port of the feeding machine often becomes blocked due to material adhesion and accumulation. Once the discharge port is blocked, it not only affects the efficiency and normal operation of feeding, but may also require manual cleaning, increasing the complexity of operation and labor costs, and may even damage the components of the feeding machine, affecting the service life of the equipment.

[0003] Currently, while there are some solutions to the problem of clogging at the discharge port of a feeding machine, such as regularly inspecting and cleaning the discharge port, these methods are reactive and cannot prevent or address clogging during its occurrence, resulting in less than ideal effectiveness. Some devices attempt to reduce clogging by modifying the discharge port's structure, but these are often complex, costly, and their anti-clogging effectiveness needs improvement. Therefore, it is necessary to design an anti-clogging device for the discharge port of a feeding machine. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging device for the discharge port of a feeding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding machine outlet anti-blocking device, comprising a feeding machine body, wherein the feeding machine body has an outlet at its discharge end;

[0006] The feeding machine body is provided with a bearing seat, in which a rolling bearing is fixedly installed. The rotating shaft passes through the inner ring of the rolling bearing and is interference-fitted with the inner ring. The two ends of the rotating shaft extend to the outside of the bearing seat to form an impeller mounting section and an agitator connecting section, respectively.

[0007] Preferably, the impeller includes a circular end plate and a plurality of arc-shaped blades evenly distributed on one side of the end plate. A stepped hole is provided in the center of the end plate, and a shoulder adapted to the stepped hole is provided at the end of the rotating shaft. The end plate is fixedly connected to the shoulder by bolts, and the bending direction of the blades is adapted to the injection direction of the high-pressure air.

[0008] Preferably, the agitator includes a connecting plate and at least three steel wires fixed to one side of the connecting plate. The connecting plate is detachably connected to the end of the rotating shaft by countersunk screws. The steel wires are radially distributed along the circumference of the connecting plate, and the ends of the steel wires away from the connecting plate are twisted in the same direction to form a spiral structure.

[0009] Preferably, an annular protective cover is provided on the outside of the discharge port, and the annular protective cover is fixedly connected to the outer wall of the discharge port by multiple supporting ribs. The impeller is located inside the annular protective cover, and the annular protective cover is provided with an interface for connecting to a high-pressure air pipe.

[0011] Beneficial effects:

[0012] (1) The present invention has a novel structural design.

[0024] Please see Figures 1-3 This utility model discloses a device for preventing blockage at the discharge port of a feeding machine, including a feeding machine body 1, and a discharge port 2 is provided at the discharge end of the feeding machine body 1.

[0025] The feeding machine body 1 is provided with a bearing seat, and a rolling bearing is fixedly installed in the bearing seat. The rotating shaft passes through the inner ring of the rolling bearing and is interference-fitted with the inner ring. The two ends of the rotating shaft 3 extend to the outside of the bearing seat to form an impeller 4 mounting section and an agitator 5 connecting section.

[0026] In this invention, the impeller 4 includes a circular end plate 6 and a plurality of arc-shaped blades 7 evenly distributed on one side of the end plate 6. A stepped hole is formed in the center of the end plate 6, and a shoulder adapted to the stepped hole is provided at the end of the rotating shaft 3. The end plate 6 is fixedly connected to the shoulder by bolts. The bending direction of the blades 7 is adapted to the injection direction of the high-pressure air. When high-pressure air is blown out from the pipe inside the feeder body, it drives the impeller to rotate, which in turn causes the agitator to stir within the discharge port via the rotating shaft, preventing blockage of the discharge port.

[0027] In this invention, the agitator 5 includes a connecting disc 8 and at least three steel wires 9 fixed to one side of the connecting disc 8. The connecting disc 8 is detachably connected to the end of the rotating shaft 3 via countersunk screws. The steel wires 9 are radially distributed along the circumference of the connecting disc 8, and the ends of the steel wires 9 away from the connecting disc 8 are twisted in the same direction to form a spiral structure. The diameter of the steel wires 9 in the agitator 5 is 3-8 mm. The cylindrical space formed by the rotation trajectory of the steel wires 9 in the discharge port 2 forms an annular gap with the inner wall of the discharge port. The rotation of the rotating shaft drives the agitator to rotate, and the agitator agitates within the discharge port. During the process of material discharge from the discharge port, the agitator continuously stirs and agitates the material within the discharge port, allowing the material to be discharged smoothly from the discharge port.

[0028] In this invention, an annular protective cover 10 is provided on the outer side of the discharge port 2. The annular protective cover 10 is fixedly connected to the outer wall of the discharge port 2 by multiple supporting ribs 11. The impeller 4 is located inside the annular protective cover 10. The annular protective cover 10 is provided with an interface for connecting to a high-pressure air pipe. This structure can protect the impeller.

[0029] Working Principle: First, the annular shroud of the device has a pre-installed high-pressure air pipe interface. High-pressure air enters the shroud through this interface and impacts the arc-shaped blades of the impeller. Because the bending direction of the blades matches the direction of the airflow, the thrust of the airflow drives the impeller to rotate around the shaft. The shaft is connected to a rolling bearing in the bearing housing via an interference fit. The rotation of the impeller synchronously drives the shaft, transmitting power to the agitator at the other end of the shaft. The agitator's steel wires are radially distributed with helical ends. As it rotates with the shaft inside the discharge port, it agitates and stirs the material about to be discharged. Simultaneously, the rotation trajectory of the steel wires forms an annular gap with the inner wall of the discharge port, preventing scraping against the inner wall and breaking up any adhered or accumulated material, ensuring smooth discharge and preventing blockages at the source.

[0030] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
