[0002] The information disclosed in the background of the invention is only intended to enhance the understanding of the overall background of the invention and should not be necessarily regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0003] As an important crop, sweet sorghum has been widely used in food, feed, bioenergy and other fields. In order to meet the needs of different application scenarios, it is particularly important to effectively grind sweet sorghum. However, the existing sweet sorghum processing and grinding devices still have many shortcomings in practical applications.

[0004] First, existing equipment generally has difficulty in achieving continuous large-scale production. Due to design limitations, these devices can only process smaller batches of raw materials, resulting in low overall production capacity and unable to meet the needs of large-scale industrial production.

[0005] Secondly, the complex structure of the equipment is another significant problem. The complex internal structure makes it very difficult to disassemble and clean, especially after long-term operation, the problem of material residue is particularly prominent. The long-term accumulation of residues may not only lead to bacterial growth, but also affect the hygiene and safety of the final product.

[0006] Furthermore, the functions of traditional sweet sorghum processing and grinding equipment are relatively simple, usually only completing basic crushing or grinding tasks, and lacking other functions such as shelling of raw materials. This functional limitation limits the application scope of the equipment and also increases the equipment investment cost in the entire production process. Summary of the invention

[0007] In view of the problems existing in the prior art, the object of the present invention is to provide a sweet sorghum processing and grinding device which can realize continuous large-scale production, is easy to maintain and clean, and has multifunctional integrated characteristics.

[0008] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A multifunctional sweet sorghum processing and grinding device comprises a frame, on which a processing bin is fixed;

[0011] The processing unit comprises a rotating drum, and a spiral substrate is fixedly mounted on the side wall of the rotating drum;

[0012] The spiral base comprises a plurality of groups of convex spiral segments, each group of convex spiral segments comprises a coarse gradual change segment and a fine gradual change segment, and the coarse gradual change segment is fixed with a spiral protrusion, so that the material is intermittently squeezed or ground during the transmission of the processing unit, so as to be shelled or ground;

[0013] The processing chamber is provided with a feed inlet near the inlet end and a discharge outlet near the bottom of the outlet end;

[0014] A separation chamber is provided below the processing chamber, a collecting port is provided below the separation chamber, and a pressure reduction chamber is connected to the top of the separation chamber;

[0015] A vertical downward discharge channel is arranged below the discharge port, a vent communicating with the separation bin is opened on the side wall of the discharge channel, and an air duct is arranged on the side wall opposite to the vent for post-processing of material shelling.

[0016] Preferably, a lining plate is fixedly installed on the bottom of the processing chamber, and the lining plate is provided with a plurality of lining channels adapted to the processing unit.

[0017] Preferably, a corresponding high-pressure air nozzle is installed at the bottom of each liner channel near the feed port to clean up residual materials.

[0023] The present invention integrates multiple functions such as shelling and grinding. By adjusting the selection of processing units and lining plates, it can flexibly adapt to different processing requirements, such as grinding of different coarseness or shelling treatment. This design simplifies the entire production process, reduces the need for multiple special equipment, and thus reduces equipment investment costs.

[0024] The present invention utilizes a spiral conveying structure formed by combining a spiral base with a rotating drum and a specially designed convex part to produce intermittent squeezing or grinding during material transmission. This mechanism not only helps to improve processing efficiency, but also ensures that the material is fully and evenly processed, thereby improving product quality.

[0025] The present invention can realize continuous operation by adopting multiple rotatable processing units arranged in horizontal rows, and these units are connected by sprocket transmission. This solves the problem that the existing equipment is difficult to achieve continuous production, improves the overall production capacity, meets the needs of large-scale industrial production, and has a strong throughput capacity for large-scale production.

[0032] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0033] Figures 1 to 4 A multifunctional sweet sorghum processing and grinding device is shown, comprising a frame 100, on which a processing chamber 2 is fixed;

[0034] A plurality of rotatable processing units 3 arranged in horizontal rows are installed in the processing chamber 2, and an inspection door 21 is provided on the top of the processing chamber 2;

[0035] The processing unit 3 comprises a rotating drum, a spiral base 32 is fixedly mounted on the side wall of the rotating drum, a rotating shaft 31 is arranged at the center of the end of the rotating drum, and the rotating shafts 31 of the processing units 3 are connected by a sprocket 311 and driven by a driving device such as a reducer to rotate together;

[0036] The spiral base 32 includes a plurality of groups of convex spiral segments, each group of convex spiral segments includes a coarse gradual change segment 321 and a narrow gradual change segment 322. The so-called coarse gradual change segment 321 means that the width of the spiral base 32 gradually becomes wider. Similarly, the so-called narrow gradual change segment 322 means that the width of the spiral base 32 gradually becomes thinner, and the joints are streamlined. The coarse gradual change segment 321 is fixed with a spiral protrusion 33, so that the material is intermittently squeezed or ground during the transmission of the processing unit 3, so as to perform shelling or grinding;

[0037] The processing chamber 2 is provided with a feed port 1 near the inlet end, and a discharge port is provided near the bottom of the outlet end;

[0038] A separation chamber 6 is provided below the processing chamber 2, a collecting port 63 is provided below the separation chamber 6, and the top of the separation chamber 6 is connected to the decompression chamber 7 through a decompression port 62;

[0039] A vertical downward discharge channel 4 is provided below the discharge port, and a vent 61 communicating with the separation bin 6 is provided on the side wall of the discharge channel 4. An air duct 5 is provided on the side wall opposite to the vent 61 for post-processing of the material after shelling.

[0040] The top of the decompression chamber 7 is provided with an air outlet 71 , and the air outlet 71 and the decompression port 62 are both installed with corresponding filters.

[0041] A lining plate 22 is fixedly installed at the bottom of the processing chamber 2, and the lining plate 22 is provided with a plurality of lining channels 221 adapted to the processing units 3. The function of the lining plate 22 and its lining channels 221 is to be assembled with suitable processing units 3 to produce corresponding processing effects.

[0042] A corresponding high-pressure air nozzle 8 is installed at the bottom of each lining channel 221 near the feed port 1, which can also be a pulse air nozzle for cleaning residual materials, and can be cleaned before each shutdown.

[0043] The functions and working process of the present invention are:

[0044] When grinding sweet sorghum, a suitable processing unit 3 is selected according to actual needs (small gap), and a liner 22 with a suitable liner 221 is selected according to the processing unit 3. After installation, the processing unit 3 starts to rotate together and the grinding state is started.

[0045] In this process, the ground material goes vertically downward from the discharge port and out through the discharge channel 4, completing the grinding operation. At this time, there is no blowing in the air duct 5.

[0046] When shelling sweet sorghum, a suitable processing unit 3 is selected according to actual needs (larger gap), and a liner 22 with a suitable liner 221 is selected according to the processing unit 3. After installation, the processing unit 3 starts to rotate together to start the shelling state of squeezing and kneading.

[0047] During this process, the mixture of sweet sorghum rice grains and rice husks is discharged through the discharge channel 4. At this time, the positive pressure wind is turned on in the air duct 5, and the husked rice husks are blown into the separation bin 6 through the air port 61. Under the action of the separation bin 6 and the pressure reduction bin 7, the rice husks fall through the collection port 63, and the husking operation is completed.

[0048] Working principle of the present invention: the rotating drum and the spiral base 32 can form a spiral conveying structure, so the processing unit 3 in the present invention has the function of conveying materials. On this basis, the spiral protrusion 33 plays the role of a cam, so that intermittent extrusion or grinding can be generated during the material conveying process.

[0049] Moreover, the spiral base 32 in the present invention includes multiple groups of convex spiral segments, and each group of convex spiral segments includes a coarse gradual change segment 321 and a fine gradual change segment 322. Therefore, the material undergoes multiple indirect intersection extrusions or grindings, thereby ensuring the processing effect.

[0050] The present invention can realize various functions including grinding and shelling by selecting spiral bases 32 of different specifications and their matching spiral protrusions 33, and then cooperating with corresponding lining plates 22.
