Description

Technical Field

[0001] The present invention relates to the technical field of highland barley processing, and more specifically, to an integrated machine for removing impurities and grinding highland barley into powder. Background Art

[0002] As a plateau crop rich in nutritional value, highland barley can be directly consumed as the main food or ground into flour to make various pasta, providing diverse tastes and nutrition for consumers.

[0003] In order to obtain higher-quality highland barley raw materials, impurity removal treatment is required. First, after the highland barley raw materials are harvested, they are initially screened by a vibrating screen to remove large impurities such as stones and soil clods. Then, the highland barley that has undergone preliminary screening enters the cleaning process, where the surface is cleaned using high-pressure water to remove impurities such as dust and pesticide residues. The cleaned highland barley is soaked in water for a period of time to fully absorb water and expand, softening the highland barley grains, which not only facilitates the removal of attached impurities but also facilitates the subsequent hulling and grinding processes of highland barley.

[0004] During the above-mentioned impurity removal process of highland barley, after the highland barley absorbs water and expands, centrifugal force is usually used to drain the water on its surface. Although softened highland barley grains are obtained, which are convenient for subsequent hulling operations, it also results in some water-containing highland barley husks remaining in the hulled highland barley grains. Due to the presence of water, the water-containing highland barley husks are tightly combined with the highland barley kernels, making it difficult to effectively separate them in the subsequent screening process, thus affecting the purity and final processing quality of highland barley.

[0005] Therefore, the present application proposes an integrated machine for removing impurities and grinding highland barley into powder to solve the above problems. Summary of the Invention

[0017] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows: 1.

At the same time, the elastic rebound assembly rebounds the highland barley, so that the attached highland barley husks are dried and separated. After the heavy highland barley grains are dried by the hot air, they fall to the lower air extraction area of the semi-circular air duct, and are screened for crushed grains by the arc-shaped sieve plate. The high-quality highland barley is discharged from the discharge port, effectively treating the water-containing highland barley husks and improving the highland barley purity and processing quality.

[0018] 2. By driving the motor to drive the central shaft and the striking arc plate to rotate, intermittent impact on the extrusion cross plate in the inner frame groove is realized, so that the transverse blocking cross plate slides to block or open the bifurcated discharge port, thereby intermittently controlling the input of highland barley and reducing the load of subsequent air separation and impurity removal in the semi-circular air duct.

[0019] 3. By setting the air source generator, semi-circular air bag and air pipe, the air source generator inflates the semi-circular air bag through the air pipe, making it bounce the highland barley grains, improving the impurity removal efficiency, promoting hot air drying, and improving the highland barley purity. The wear-resistant layer enhances the durability of the air bag and extends the service life of the elastic rebound assembly.

[0020] 4. By setting the discharge port, air extraction pump, air pipe and air flow valve, effective air extraction from the upper and lower air extraction areas of the semi-circular air duct is achieved. The upper discharge port and the right-angle air pipe 1 are responsible for sucking the hulls in the upper air extraction area, and the lower discharge port and the right-angle air pipe 2 reduce the influence of rice dust in the lower air extraction area.

Detailed implementation manners

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] By providing a hulling and milling integrated machine for removing impurities from highland barley in the embodiments of the present application, the problem that after the highland barley that has undergone water absorption expansion and centrifugal dehydration is hulled during the impurity removal process, the remaining water-containing highland barley husks are difficult to screen and separate from the highland barley kernels, affecting the purity and processing quality of highland barley is solved. When in use, by using the semi-circular air duct 5, the elastic rebound assembly 6 and the air extraction assembly 12, the removal of highland barley husks and impurities attached to the highland barley husks contained in the highland barley is realized, and the purity and processing quality of highland barley are improved.

[0039] The technical solutions in the embodiments of the present application are generally as follows to solve the above technical problems.

[0040] Embodiment 1: Please refer to Figures 1 - 15, a hulless barley impurity removal and flour milling integrated machine, including a box body 1, and further including: a feed hopper 2 installed at the top of the box body 1; a bifurcated discharge port 3 installed at the bottom of the feed hopper 2; a grain inlet component 4 installed inside the bifurcated discharge port 3 for shunting and discharging the accumulated hulless barley grains in batches; two semi-circular air ducts 5 respectively installed on the left and right sides inside the box body 1, and the upper middle parts of the outer ring walls of the two semi-circular air ducts 5 are respectively communicated with the left and right sides of the bifurcated discharge port 3; a bounce component 6 installed in the middle of the inner ring wall of the semi-circular air duct 5 for elastically bouncing the hulless barley grains first discharged into the semi-circular air duct 5; a debris port 7 installed at the top of the inner ring wall of the semi-circular air duct 5, and the inclination angle of the debris port 7 is set at 30-45 degrees; an inclined filter plate 8 installed in the middle of the debris port 7, and the top end of the inclined filter plate 8 is connected to the inner wall of the top of the outer ring wall of the semi-circular air duct 5; heating arc plates 9 are buried in the inner walls of the upper inner and outer ring walls of the semi-circular air duct 5, a radian sieve plate 10 is installed at the middle and lower part of the outer ring wall of the semi-circular air duct 5, a discharge port 11 is installed at the bottom end of the outer ring wall of the semi-circular air duct 5, and the discharge port 11 penetrates through the inner walls of the left and right sides at the bottom end of the box body 1; an air extraction component 12 is arranged on one side of the semi-circular air duct 5 facing outward, and the air extraction component 12 is communicated with both ends of the semi-circular air duct 5.

[0041] By setting the semi-circular air duct 5, the debris port 7, the inclined filter plate 8, the heating arc plate 9, the radian sieve plate 10 and the discharge port 11, the hulless barley grains are injected into the box body 1 through the feed hopper 2 (ramp plates are also installed on both sides inside the feed hopper 2, refer to Figure 5As shown, it can be matched with the round-headed horizontal box 401 in the particle-entering component 4 to form a highland barley input diversion path), and the forked discharge port 3 and the particle-entering component 4 are diverted and discharged in batches into the upper exhaust zone in the semi-annular air duct 5 on both sides. On the one hand, when the highland barley first enters the semi-annular air duct 5, the relatively light highland barley skin will be attracted by the hot air drying in the upper exhaust zone of the semi-annular air duct 5 (the hot air is heated by the heating arc plate 9, and the exhaust component 12 is used to extract hot air to form hot air attraction, and the attracted highland barley skin can be dried during the transportation process), and transported upward to the position of the inclined filter plate 8 for interception and collection. On the other hand, since the discharge port of the forked discharge port 3 faces the corresponding rebound component 6, the discharged highland barley will contact the rebound component 6, and the highland barley will rebound upward for a distance under the influence of the rebound component 6. During the rebound and rising process, the highland barley skin attached to the highland barley itself is subjected to a secondary hot air dehumidification. Separation and drying (wherein, the middle part of the semi-annular air duct 5 is the dividing line, the upper area of ​​the semi-annular air duct 5 is the upper air pumping area, and the lower area of ​​the semi-annular air duct 5 is the lower air pumping area, and the specific action length of the air pumping is also the dividing line with the middle part of the semi-annular air duct 5), and the highland barley grains with larger mass, on the one hand, are affected by the rebound component 6, and will be attracted by the hot air in the upper air pumping area. This process can improve the drying effect of the highland barley grains. On the other hand, due to their own large mass, they will fall into the lower air pumping area of ​​the semi-annular air duct 5, and be rolled and screened through the arc sieve plate 10 at the lower part of the semi-annular air duct 5, thereby screening out the broken highland barley grains, and better and higher quality highland barley grains will roll to the discharge port 11 for discharge. In summary, the problem of processing the residual water-containing highland barley skin after the highland barley that has been swelled by water absorption and centrifugal dehydration is shelled in the process of highland barley impurity removal is solved, thereby improving the purity and processing quality of highland barley.

[0042] For further information, see Figure 15 A number of air permeable filter holes 13 are arranged equidistantly in the upper middle part of the inclined filter plate 8, and the inner side of the inclined filter plate 8 is arranged in an arc surface. The air permeable filter holes 13 can make the ventilation effect of the inclined filter plate 8 more significant and smooth, and it is also convenient for the exhaust component 12 to perform exhaust operation on the upper exhaust area of ​​the semi-annular air duct 5. The arc surface setting of the inclined filter plate 8, on the one hand, increases the contact area between the attracted barley husk and the inclined filter plate 8, so that more impurities are trapped thereon. On the other hand, it helps to disperse the stress concentration of the inclined filter plate 8 when it is subjected to force, and reduce the risk of damage caused by excessive stress. Compared with the plane structure, the arc surface design can better absorb and disperse energy when impacted, thereby improving the impact resistance of the inclined filter plate 8.

[0043] For further information, see Figure 9, impurity collection boxes 14 are installed on the upper inner walls of the left and right sides of the box body 1. The top end of the impurity collection box 14 is communicated with the bottom end of the debris opening 7. By setting the impurity collection box 14, when the inclined filter plate 8 needs to be cleaned, only the air extraction component 12 needs to be stopped, and the dried hulled barley skins on it will gradually fall into the impurity collection box 14 for collection. It should be noted that when the air extraction component 12 stops working, the feeding into the semi-circular air duct 5 also needs to be stopped to avoid corresponding problems.

[0044] Further, please refer to Figure 9 and Figure 10 , crushing boxes 15 are installed on the left and right sides of the middle part of the bottom end of the box body 1, and a plurality of partition plates 16 are installed in the crushing boxes 15. By setting the crushing boxes 15 and the partition plates 16, the system can effectively collect the crushed hulled barley grains screened by the arc-shaped sieve plate 10 by using the crushing boxes 15. The partitioning effect of the partition plates 16 in the internal space of the crushing boxes 15 forms a plurality of independent storage spaces. These spaces are not only used to temporarily store the fallen crushed hulled barley grains, but also can effectively prevent the crushed hulled barley grains from accumulating widely during the falling process, thereby reducing the generation and flying of rice dust and avoiding polluting the internal space of the semi-circular air duct 5.

[0045] Further, please refer to Figure 3 , a base 20 and a collecting hopper 21 are respectively installed on the outer and middle parts of the bottom end of the box body 1. A flour mill 22 is installed on the bottom wall of the base 20, and the feeding port of the flour mill 22 is connected to the bottom end of the collecting hopper 21. A powder discharge port 23 is installed at the rear end of the flour mill 22 and penetrates through the rear wall of the base 20 and extends to the outside. By setting the base 20, the collecting hopper 21, the flour mill 22 and the powder discharge port 23, the collecting hopper 21 can be used to centrally discharge the hulled barley grains in the two discharge ports 11 and convey them into the flour mill 22 for flour milling treatment. The hulled barley flour after flour milling is discharged through the powder discharge port 23 for collection and utilization.

[0046] Embodiment 2: Please refer to Figures 4 - 8 , the incoming grain component 4 includes: a round-headed horizontal box 401, which is of a hollow structure and is installed in the middle of the bifurcated discharge port 3; inner frame grooves 402, which are respectively installed on the left and right sides of the round-headed horizontal box 401; an extrusion horizontal plate 403, which is slidably installed in the middle of the inner frame groove 402, and a horizontal blocking horizontal plate 404 is installed at the outer end of the extrusion horizontal plate 403, and the horizontal blocking horizontal plate 404 also slides in the inner frame groove 402; a return spring 405, one end of which is connected to the front and rear parts of the outer end of the extrusion horizontal plate 403, and the other end is connected to the inner wall of the inner frame groove 402 at the inner end; a central shaft 406, which is arranged between the two inner frame grooves 402, and the central shaft 406 is rotatably installed in the middle of the round-headed horizontal box 401, and striking arc plates 407 are installed on the upper and lower parts of the central shaft 406; a driving motor 408, which is installed in the front middle part of the bifurcated discharge port 3, and the output end of the driving motor 408 penetrates through the front wall of the bifurcated discharge port 3 and is fixedly connected to one end of the central shaft 406.

[0047] By setting the round-headed horizontal box 401, inner frame groove 402, extrusion horizontal plate 403, horizontal resistance horizontal plate 404, return spring 405, central shaft 406, striking arc plate 407 and drive motor 408, the drive motor 408 is used to drive the connected central shaft 406 to rotate. The rotating central shaft 406 will drive the striking arc plate 407 installed on itself to rotate (the striking arc plate 407 rotates to the left and right positions), and synchronously impact and extrude the extrusion horizontal plates 403 in the inner frame grooves 402 on both sides, so that the extrusion horizontal plates 403 and the horizontal resistance horizontal plates 404 connected thereto slide stably in the inner frame grooves 402, and the horizontal resistance horizontal plates 404 will also move outward to block the falling gaps on the left and right sides between the bifurcated discharge ports 3 and the round-headed horizontal box 401, blocking the input of highland barley above. When the central shaft 406 drives the striking arc plate 407 to continue rotating (the striking arc plate 407 rotates to the upper and lower positions), the extrusion horizontal plate 403 is not under pressure and will reset through the return spring 405, causing the horizontal resistance horizontal plate 404 to retract into the inner frame groove 402, and the highland barley above can continue to be input. Through the above operations, the batch input of highland barley can be intermittently controlled, reducing the operating load for the subsequent air separation and impurity removal operation of the semi-circular air duct 5.

[0048] Further, please refer to Figure 9 、 Figure 11 and Figure 12 As shown in FIGS. and, the elastic rebound assembly 6 includes: air source generators 601, two of which are respectively installed at the lower parts of the left and right inner walls of the box body 1; semi-circular air bags 602, installed in the middle of the inner ring wall of the semi-circular air duct 5; air pipes 603, one end of which is communicated with the exhaust port of the air source generator 601, and the other end of which is communicated with the outer side of the semi-circular air bag 602; wear-resistant layers 604, provided on the outer wall of the semi-circular air bag 602.

[0049] By setting the air source generator 601, semi-circular air bag 602, air pipe 603 and wear-resistant layer 604, the air source generator 601 is used to inflate the semi-circular air bag 602 through the air pipe 603. After the semi-circular air bag 602 contacts the discharged highland barley grains, an elastic effect is triggered, ensuring that the semi-circular air bag 602 can stably generate elastic force, realizing continuous elastic treatment of the highland barley grains, effectively improving the processing efficiency of highland barley impurity removal, and also helping the attachments and fine impurities on the surface of the highland barley grains to receive hot air drying and suction, thereby improving the purity of the highland barley. In addition, the setting of the wear-resistant layer 604 significantly enhances the durability of the semi-circular air bag 602, reduces the wear during the contact with the highland barley grains, and extends the service life of the elastic rebound assembly 6.

[0050] Further, please refer to Figure 5 and Figure 9, the lower sides of both openings of the bifurcated discharge port 3 are obliquely arranged, and the opening directions face the positions of the corresponding semi-circular air bags 602. The opening directions of the bifurcated discharge port 3 are aligned with the corresponding semi-circular air bags 602, enhancing the contact efficiency between the falling hulled barley grains and the semi-circular air bags 602, enabling the hulled barley grains to impact the surface of the semi-circular air bags 602 more directly and evenly, enabling it to perform the bounce-back operation more effectively, not only improving the processing efficiency of the hulled barley grains but also ensuring the uniform force on the semi-circular air bags 602 and extending their service life.

[0051] Embodiment 3: Please refer to Figure 9 , Figure 11 and Figure 14 , the air extraction assembly 12 includes: a horizontal discharge port 1201, respectively installed at both ends of the semi-circular air duct 5, and a filter screen is installed inside it; an air extraction pump 1202, arranged on the outer side of the horizontal discharge port 1201, and a double-headed air pipe 1203 is installed at the air extraction port of the air extraction pump 1202; a right-angle air pipe one 1204, one end of which is connected to one of the connection ends of the double-headed air pipe 1203, and the other end is connected to the outer end of the upper horizontal discharge port 1201; a right-angle air pipe two 1205, one end of which is connected to the other connection end of the double-headed air pipe 1203, and the other end is connected to the outer end of the lower horizontal discharge port 1201; air flow valves 1206, respectively installed in the middle of the right-angle air pipe one 1204 and the right-angle air pipe two 1205.

[0052] By setting the horizontal discharge port 1201, the air extraction pump 1202, the double-headed air pipe 1203, the right-angle air pipe one 1204, the right-angle air pipe two 1205 and the air flow valves 1206, effective air extraction of the upper and lower air extraction areas of the semi-circular air duct 5 in Embodiment 1 is achieved. Specifically, the upper horizontal discharge port 1201 cooperates with the right-angle air pipe one 1204 to be responsible for the air extraction operation of the upper air extraction area of the semi-circular air duct 5, while the lower horizontal discharge port 1201 cooperates with the right-angle air pipe two 1205 to be responsible for the air extraction operation of the lower air extraction area. These two groups of air pipes are both connected to the air extraction pump 1202 through the double-headed air pipe 1203 to achieve the air extraction function. At the same time, the air flow valves 1206 are used to respectively control the air extraction intensity of the right-angle air pipe one 1204 and the right-angle air pipe two 1205. Among them, the right-angle air pipe one 1204 is mainly responsible for sucking the hulls in the upper air extraction area of the semi-circular air duct 5, while the right-angle air pipe two 1205 is mainly responsible for reducing the impact of the rice dust formed by the fall in the lower air extraction area, meeting the different air extraction requirements of the upper and lower areas of the semi-circular air duct 5. The filter screen of the horizontal discharge port 1201 needs to be replaced and cleaned regularly.

[0053] Furthermore, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 9, partition chambers 17 are provided on both the left and right sides of the box body 1, and air extraction pumps 1202 are installed on the inner middle walls of the partition chambers 17 facing inwards. Assembly plates 18 are installed on the left and right parts of the front and rear sides of the box body 1, and air permeable plates 19 are installed on the left and right parts of the assembly plates 18.
