Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rice processing, and in particular to a material feeding hopper balancing discharging device for a rice processing production line. BACKGROUND

[0002] In the automatic production line of rice processing, the material feeding hopper, as the key equipment connecting the storage link and the processing equipment (such as a rice mill, a color sorter, and a polishing machine), bears the dual functions of material temporary storage and uniform feeding. Its performance directly affects the stability of the subsequent process: on the one hand, it is necessary to convert the rice from a static storage state to a continuous flow state to ensure the stability of the feeding amount of the processing equipment; on the other hand, it is necessary to avoid the increase of broken rice rate caused by extrusion and friction during the conveying process.

[0003] The vertical section of the traditional material feeding hopper is mostly designed as a straight cylinder. The rice forms a non-uniform flow state with "fast central flow speed and slow edge flow speed" under the action of gravity, and there is a certain flow speed difference. This flow speed difference will cause the recognition accuracy of the subsequent color sorter to decrease and the rolling pressure of the rice mill to be uneven. When the moisture content of the rice exceeds a certain amount, the adhesion and friction between the particles significantly increase, and a stable "arch structure" is easily formed on the inner wall of the vertical section of the material feeding hopper, resulting in interruption of discharging. The stirring mechanism of the existing material feeding hopper is mostly designed with a single rotating shaft, and the stirring range is limited, which easily causes material accumulation in the corners and leads to uneven mixing of new and old materials. The fixed baffle is mostly used in the material distribution link, and the material distribution angle cannot be dynamically adjusted according to the feeding amount. When the feeding amount suddenly changes, the "material rushing" phenomenon easily occurs. SUMMARY

[0035] The implementation principle of the equalizing and discharging device of the feeding hopper for a rice processing production line is as follows: the electrical components appearing in the application are externally connected to a power supply and a control switch during use; when rice material enters the feeding hopper 1, the motor 3 drives the connecting shaft 21 to rotate, the connecting disc 22 drives the plurality of rotating blades 23 to synchronously rotate, the falling material is scattered to avoid local accumulation at the bottom of the feeding hopper 1. At the same time, the driving motor 5 drives the stirring mechanism to work through the driving assembly: the driving motor 5 drives one of the stirring rods 19 to rotate, the gear 8 on the stirring rod 19 meshes with the gear ring 7 outside the supporting ring 6, since the gear ring 7 is rotationally connected to the T-shaped connecting groove of the supporting ring 6 through the T-shaped connecting ring 24, the gear 8 drives the gear ring 7 to rotate as a whole when the gear 8 rotates, thereby driving the remaining stirring rods 19 to synchronously rotate. The annular array distributed stirring rods 19 drive the stirring blades 20 to rotate in all directions in the feeding hopper 1, the material accumulated in the corners is stirred and dispersed to prevent the material from caking due to static placement, and ensure that the material in the feeding hopper 1 is uniformly mixed. Moreover, the stirring blades 20 close to the vertical plate 18 on the stirring rod 19 will not collide with each other during rotation due to the length limitation. After the stirred material enters the discharging groove of the discharging box 9, the material distribution mechanism starts to work. The controller 13 controls the synchronous electric cylinder 17 to extend and retract according to preset parameters or sensor feedback signals (such as the feeding requirement of subsequent equipment). The output end of the synchronous electric cylinder 17 drives the mounting plate 15 to ascend and descend, and the mounting plate 15 drives the sliding block 25 to slide in the sliding groove 14 of the fixed plate 12 through the hinged transmission of the first connecting seat 26, the connecting strip 28 and the second connecting seat 27. The sliding block 25 drives the material distribution plates 10 to synchronously move in the horizontal direction through the connecting rod 11, so as to adjust the distance between the two material distribution plates 10. Then the rice continues to fall downward through the inclined surface 29 of the material distribution plate 10, so as to realize the discharging work. When it is necessary to adjust the discharging amount, the synchronous electric cylinder 17 changes the opening degree of the material distribution plate 10 to accurately control the cross-sectional area of the material passing through, so as to realize the dynamic adjustment of the flow. During the whole process, the controller 13 coordinates the working rhythm of the motor 3, the driving motor 5 and the synchronous electric cylinder 17, so as to match the stirring intensity, the material distribution speed and the requirement of the subsequent processing equipment, and ensure that the discharging is uniform and continuous.
