Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment for starch production, in particular to a spiral feeding barrel. Background Art

[0002] Sweet potato starch is also known as sweet potato starch, sweet potato starch, sweet potato starch, yam starch, mountain powder, etc. It is a powder made from sweet potato starch, etc. Generally, sweet potato powder is granular, and there are two types of coarse and fine particles. Sweet potato starch has strong water absorption capacity and can be used to make snacks, vermicelli, rice paper, etc. Sweet potato starch is darker in color, the particles are relatively rough, and the viscosity is difficult to control after gelatinization, so it is mostly used to make Chinese snacks, such as mountain powder dumplings. Because of its smooth taste and toughness, it is also very suitable for making vermicelli and rice paper. The sweet potato powder often used in hot pot is made of it. In the production process of sweet potato starch, a spiral loading barrel is needed to transport the material. The spiral loading barrel is a machine that uses a motor to drive the spiral rotation to push the material to achieve the purpose of transportation. It can be horizontal, inclined or vertical. Conveying has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. The spiral loading barrel is suitable for non-sticky dry powder materials and small particle materials (such as cement, fly ash, lime, grain, etc.). When the existing spiral loading barrel is working, the sweet potato starch is first accumulated in the hopper, and the sweet potato starch falls into the loading barrel by its own gravity. The motor drives the spiral blades to rotate to push the material to achieve the purpose of spiral conveying. In the traditional spiral loading barrel conveying process, when there is too much sweet potato starch in the hopper, the sweet potato starch is easy to accumulate inside the hopper and will not fall, affecting the production progress. The angle of the spiral loading barrel is fixed and cannot be adjusted according to the actual situation. For this reason, we propose a spiral loading barrel. Utility Model Content

A material discharging mechanism is provided to effectively avoid the accumulation and blockage of sweet potato starch in the hopper of the spiral loading barrel. An angle adjustment mechanism is also provided to quickly and accurately adjust the deflection angle of the spiral loading barrel according to actual conditions.

[0028] The working principle of a spiral loading barrel provided by the utility model is as follows: when conveying sweet potato starch, the angle of the spiral loading barrel is adjusted first. When the spiral loading barrel needs to be deflected upward, the single chip microcomputer 10 controls the motor 2 77 to rotate forward, and the output shaft of the motor 2 77 drives the worm 76 to rotate forward. Because the worm 76 is meshed with the worm wheel 72, the worm wheel 72 will rotate accordingly, driving the bidirectional screw rod 71 to rotate forward. Because the inner middle of the slider 73 is threadedly connected to the outer surface of the bidirectional screw rod 71, the two sliders 73 will move inward with the rotation of the bidirectional screw rod 71. The connecting rod 75 is connected to the slider 73 and the connecting block 74 on the same side. Therefore, as the slider 73 moves inward, the connecting rod 75 will slowly move inward, continuously squeezing the connecting block 74, causing the pin to move along the strip-shaped opening 11, and the housing 3 deflects upward to achieve the upward deflection of the spiral loading barrel. When the spiral loading barrel needs to be deflected downward, the single-chip microcomputer 10 controls the motor 2 77 to rotate forward, and the output shaft of the motor 2 77 drives the worm 76 to reverse, and the bidirectional screw 71 also reverses synchronously, and the two sliders 73 move outward with the rotation of the bidirectional screw 71. The connecting rod 75 also moves slowly outward, so that the connecting block 74 deflects downward with the shell 3, realizing the downward deflection of the spiral feeding barrel. After the angle of the spiral feeding barrel is adjusted, the feeding starts, and the sweet potato starch is accumulated inside the hopper 4. The single-chip microcomputer 10 controls the motor 1 67 to operate, and the output shaft of the motor 1 67 drives the pulley 2 68 to rotate. Because the pulley 2 68 is connected to the double-groove pulley 61 through the belt 2, the double-groove pulley 61 will rotate synchronously, driving the rotating shaft 63 and the spiral feeding sheet 64 to rotate. At the same time, because the pulley 1 66 is connected to the double-groove pulley 61 through the belt 2 Belt one is connected to the double-groove pulley 61 for transmission, so pulley one 66 will also rotate therewith, driving the discharging shaft 65 to rotate. The discharging rod on the outer surface of the discharging shaft 65 will break up the accumulated sweet potato starch, so that the sweet potato starch can quickly and massively fall into the shell 3, be pushed by the rotating spiral feeding piece 64, and finally flow out from the discharge port, completing the conveying of the sweet potato starch. A discharging mechanism is provided, which can effectively avoid the accumulation and blockage of sweet potato starch in the hopper of the spiral feeding barrel, and an angle adjustment mechanism is also provided, which can quickly and accurately adjust the deflection angle of the spiral feeding barrel according to actual conditions.
