Description

Technical Field

[0001] This utility model relates to the field of agricultural crop processing, specifically a device for secondary dehulling of barley kernels. Background Technology

[0002] In the barley processing industry, with the increasing market demand for high-quality barley kernels, secondary dehulling is required to further improve dehulling efficiency and product quality. This is mainly achieved by using grinding wheel friction and sieve filtration to accurately separate the outer shell and kernel of the barley kernel, thus completing the secondary dehulling of the barley kernel.

[0003] In the existing technology, traditional barley kernel hulling equipment mainly consists of a grinding wheel, a filter screen, an installation component, a power module, and a conveying module. The grinding wheel is responsible for frictional hulling, the filter screen is used for screening and separation, the installation component ensures structural stability, the power module provides the driving force for operation, and the conveying module realizes material input and output. All parts work together to complete the hulling of barley kernels.

[0004] However, in the use of traditional barley hulling equipment, the filter screen removes the outer shells from the secondary hulling process of the barley kernels. Due to the lack of external force to clear the blockage, the removed outer shells may accumulate near the filter screen, causing the filter screen to become clogged and affecting the overall hulling progress. To address this issue, this utility model proposes a secondary hulling device for barley kernels to solve the aforementioned technical problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1-7 This utility model provides a technical solution: a secondary peeling device for barley kernels, comprising: a processing box 1, a powder vacuum pump 2 installed below the processing box 1, an outer frame 4 installed on the outer wall of the processing box 1, a screen 3 installed on the inner wall of the processing box 1, a transfer frame 5 fixedly installed at the bottom of the outer frame 4, and the powder vacuum pump 2 connected below the transfer frame 5.

[0026] A grinding wheel 6 is provided, a drive assembly 7 is provided below the grinding wheel 6, and a feed frame 8 is provided directly above the grinding wheel 6;

[0027] In use, barley kernels are fed into the processing box 1 through the feeding frame 8. Then, the grinding wheel 6 is driven to rotate through the drive component 7. The rotation of the grinding wheel 6 generates friction on the barley kernels, which gradually peels off the outer shell of the barley kernels. The peeled outer shell falls into the transfer frame 5 through the filtering action of the screen 3, and is then quickly sucked away by the powder vacuum pump 2 to prevent the outer shell from accumulating between the outer frame 4 and the processing box 1. This avoids the problem of the filter screen clogging affecting the barley kernel peeling progress.

[0028] Example 2: Based on Example 1, a sanding disc 16 is provided to facilitate secondary hulling of barley kernels. Several limiting blocks are formed on the surface of the sanding disc 16. A grinding wheel 6 is positioned above the sanding disc 16, and several limiting grooves 17 are formed at the bottom of the grinding wheel 6. The limiting grooves 17 fit with the limiting blocks on the surface of the sanding disc 16. A top cover 18 is provided on the upper surface of the grinding wheel 6, and the top cover 18 is fitted onto the drive shaft 12. A rotating rod 19 is fitted above the top cover 18, and a reverse nut 20 is provided above the rotating rod 19. The inner thread of the reverse nut 20 is threadedly connected to the outer thread at the upper end of the drive shaft 12. A drive assembly 7 is fixedly installed at the lower end of the drive shaft 12. A turntable 14 is fixedly installed on the outer wall of the drive shaft 12. Several Bomi knives are fixedly installed on the side wall of the turntable 14. A clamping rod 15 is fixedly installed on the surface of the turntable 14. The sanding disc 16 is fitted onto the turntable 14, and a clamping groove is formed at the bottom of the sanding disc 16. The inner side wall of the clamping groove fits with the outer side wall of the clamping rod 15.

[0029] When installing the grinding wheel 6, the drive shaft 12 is fixedly installed in the fixed bearing 13, and the turntable 14 is fixedly installed on its outer wall surface. The grinding disc 16 is fixed in position by the locking rod 15 on the surface of the turntable 14. At the same time, a limiting block is fixedly installed on the surface of the grinding disc 16. This limiting block can match the limiting groove 17 at the lower end of the grinding wheel 6, thereby ensuring that the grinding wheel 6 is fixed in position on the grinding disc 16. Therefore, if the grinding wheel 6 needs to be replaced or adjusted, it is only necessary to remove the reverse nut 20 at the upper end of the drive shaft 12, and then remove its components one by one. This process is simple and convenient, thus facilitating the overall processing.

[0030] The processing box 1 is in the shape of a frustum. Several circumferentially spaced slots are opened on the outer wall surface of the processing box 1. A screen 3 is fixedly installed at the front of one end of the slot near the inner wall of the processing box 1. A discharge hole 9 is opened on the inner wall surface of the processing box 1. A discharge pipe 10 is fixedly installed directly below the discharge hole 9. A hole is opened at the bottom of the processing box 1. Fixed bearings 13 are fixedly installed at the upper and lower ends of the inner wall of the hole. A drive shaft 12 is fixedly installed on the inner ring surface of the fixed bearing 13.

[0031] During processing, the Bomi knife located on the side wall of the turntable 14 can continuously clear the grain at the bottom, preventing the grain from accumulating at the discharge port and causing blockage, which would affect the overall hulling. In addition, the top cover 18 has an arched structure from the edge to the center, which can prevent barley kernels from accumulating on the top cover 18. At the same time, the rotating rod 19 on the top cover 18 can evenly distribute the barley kernels entering from the feed frame 8 in the gap between the grinding wheel 6 and the screen 3, avoiding uneven distribution of barley kernels during processing, which would make processing inconvenient.

[0032] Example 3: Based on Example 2, in order to improve the quality of secondary hulling of barley kernels, an outer frame 4 is provided. The outer frame 4 is fixedly installed on the outer wall surface of the processing box 1. Several holes 11 are opened on the bottom surface of the outer frame 4. The holes 11 are located in front of the screen 3. A transfer frame 5 is fixedly installed directly below the holes 11. The side wall of the transfer frame 5 has a hole. A connecting pipe is fixedly installed in the hole. A powder vacuum pump 2 is fixedly installed at one end of the connecting pipe. A groove is opened on the side wall of the discharge pipe 10 near the discharge hole 9. A second clamping plate 22 is inserted into the groove. The second clamping plate 22 can move within the groove. Several grooves are opened on the lower middle surface of the discharge pipe 10 in a linear and equidistant arrangement. Several retention plates 23 are set between the grooves. The feeding frame 8 is installed on the outer frame 4 and the upper surface of the processing box 1. A groove is opened on one side wall of the feeding frame 8. A first clamping plate 21 is inserted into the groove. The first clamping plate 21 can move within the groove.

[0033] During processing, the first pallet 21 and the second pallet 22 can effectively control the flow rate of barley kernels in and out. During processing, the powder vacuum pump 2 can effectively adsorb the barley kernel shells in the transfer frame 5 and the shells in the processing box 1, thereby significantly reducing shell residue, improving dehulling efficiency and purity, and ensuring the cleanliness of the equipment. During the discharge process, a trough that only shells can pass through is opened on the lower surface of the middle part of the discharge pipe 10, and a retention plate 23 is installed between the troughs. The retention plate 23 can effectively slow down the discharge speed of barley kernels in the trough section, so that the barley kernel shells mixed in during the discharge process can be screened out from the trough, thereby improving the overall dehulling quality.

[0034] In actual use, barley kernels are conveyed to the processing box 1 through the feeding frame 8. Then, the grinding wheel 6 is driven to rotate through the drive component 7. The rotation of the grinding wheel 6 will generate friction on the barley kernels, thereby gradually peeling off the outer shell of the barley kernels. The peeled outer shell will fall into the transfer frame 5 through the filtering effect of the screen 3, and then be quickly sucked away by the powder vacuum pump 2 to prevent the outer shell from accumulating between the outer frame 4 and the processing box 1. This avoids the problem of the filter screen clogging affecting the barley kernel peeling progress.
