A circulating screening device for flaxseed dehulling

Abstract

This application discloses a circulating sieving device for flaxseed dehulling. A buffer support is fixed to the bottom of an inclined screen plate. The hopper is supported on both sides by support rods. A cylinder is installed on one side of the hopper, and a mounting plate spanning the inclined screen plate is located at one end of the cylinder. A brush is mounted on the lower side of the mounting plate via an adjustment component. A vibrating motor is installed on the outer side of the inclined screen plate. In use, dehulled flaxseeds fall onto the inclined screen plate through the hopper. When the vibrating motor drives the inclined screen plate to vibrate, the kernels fall below the inclined screen plate, while unhulled flaxseeds are discharged from the lower end of the inclined screen plate, thus achieving the sieving process of the dehulled flaxseeds. Simultaneously, operating the adjustment component brings the bottom of the brush into contact with the inclined screen plate. Then, by controlling the extension and retraction of the cylinder, the brush reciprocates, removing kernels stuck on the inclined screen plate. This improves cleaning effect and efficiency while ensuring high operational safety. After cleaning, the adjustment component can be operated to position the brush above the inclined screen plate.

Description

Technical Field

[0001] This utility model relates to the field of flaxseed oil processing technology, and in particular to a circulating screening device for flaxseed dehulling. Background Technology

[0002] In the production and processing of flaxseed oil, in order to improve the quality of the oil, flaxseeds need to be dehulled to obtain the kernel (also known as seed kernel or endosperm). After dehulling, in order to facilitate the separation of dehulled kernels from unhulled flaxseeds, a screening device is needed to perform a cyclic dehulling process on the unhulled flaxseeds. However, in the existing screening devices, the dehulled kernels are prone to sticking to the screen plate during use, causing blockage and affecting the screening effect. Currently, after blockage, the screen plate is mainly cleaned manually with a brush to remove the kernels stuck to the screen plate. This cleaning method is ineffective, inefficient, and poses safety risks. Utility Model Content

[0003] The purpose of this application is to provide a circulating sieving device for flaxseed dehulling, so as to solve the problems of poor cleaning effect, low efficiency and safety risks of the current cleaning method of manually brushing off the kernels stuck on the sieve plate.

[0004] To solve the above-mentioned technical problems, this application provides a circulating screening device for flaxseed dehulling, comprising: An inclined screen plate and a hopper located above the high end of the inclined screen plate are provided. Side plates are installed on both sides of the inclined screen plate. A buffer support is fixed at the bottom of the inclined screen plate. The two sides of the hopper are supported by support rods. A cylinder is installed on one side of the hopper. A mounting plate spanning the inclined screen plate is provided at one end of the cylinder. A brush is provided on the lower side of the mounting plate through an adjustment component. A vibration motor is installed on the outer side of the inclined screen plate.

[0005] In a preferred embodiment, a circulating sieving device for flaxseed dehulling includes four buffer supports, each of which includes a support leg and a buffer spring fixed to the support leg. The upper end of the buffer spring is fixedly connected to the bottom of the inclined sieve plate.

[0006] The solution requires detailed description of a circulating sieving device for flaxseed dehulling. The adjusting component includes an L-shaped scraper and a connecting plate fixed to the lower side of the mounting plate. The L-shaped scraper is positioned close to the hopper. The connecting plate has multiple vertical adjusting holes. Multiple threaded rods corresponding to the vertical adjusting holes are fixed to one side of the L-shaped scraper. The threaded rods extend through the vertical adjusting holes to one side of the connecting plate. A limit nut is screwed onto one end of each threaded rod. The brush is positioned on the lower side of the L-shaped scraper.

[0007] The solution requires further detailed explanation of a circulating screening device for flaxseed dehulling, which also includes a limiting rod fixed to one side of the hopper; Correspondingly, the mounting plate is provided with a limiting hole, and the limiting rod passes through the limiting hole through the mounting plate.

[0008] In a preferred embodiment, a circulating sieving device for flaxseed dehulling is provided, wherein the mounting plate and the connecting plate are integrally formed.

[0009] The solution requires further detailed explanation of a circulating sieving device for flaxseed dehulling, wherein a baffle is fixed at the high end of the inclined sieve plate.

[0010] Compared with the prior art, the circulating screening device for flaxseed dehulling provided by this utility model includes an inclined screen plate and a hopper located above the high end of the inclined screen plate. Side plates are installed on opposite sides of the inclined screen plate, and a buffer support is fixed at the bottom of the inclined screen plate.

One end of the cylinder is provided with a mounting plate that spans the inclined screen plate. A brush is installed on the lower side of the mounting plate through an adjustment component, and a vibrating motor is installed on the outer side of the inclined screen plate. In use, the dehulled flaxseeds fall onto the inclined screen plate through the hopper. Then, as the vibrating motor drives the inclined screen plate to vibrate, the kernels are screened out and fall below the inclined screen plate. Unhulled flaxseeds move along the inclined screen plate and are finally discharged from the lower end of the inclined screen plate, thereby realizing the screening process of dehulled flaxseeds. When it is necessary to clean the kernels stuck on the inclined screen plate, the adjustment component can be operated to bring the bottom side of the brush into contact with the inclined screen plate. Then, by controlling the extension and retraction of the cylinder, the brush is moved back and forth to brush away the kernels stuck on the inclined screen plate, which can improve the cleaning effect and efficiency and has a high degree of operational safety. After cleaning, the adjustment component can be operated to detach the brush from the inclined screen plate and position it above the inclined screen plate. Attached Figure Description

[0013] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0014] The core of this application is to provide a circulating sieving device for flaxseed dehulling, which solves the problems of poor cleaning effect, low efficiency and safety risks associated with the current method of manually brushing off the kernels stuck on the sieve plate.

[0015] Figure 1 This is a schematic diagram of a circulating screening device for flaxseed dehulling provided in an embodiment of this application. Figure 2 This is a schematic diagram of an adjustment component structure provided in an embodiment of this application. Figure 3 For a schematic diagram of another angle adjustment component provided in an embodiment of this application, see [link to schematic diagram]. Figures 1 to 3 As shown.

[0016] Example 1 A circulating screening device for flaxseed dehulling includes an inclined screen plate 1 and a hopper 2 located above the high end of the inclined screen plate 1. The structure of the hopper 2 is shown in the figure. The hopper 2 with this structure can prevent dust from being generated during the material falling. Side plates 3 are installed on both opposite sides of the inclined screen plate 1. A vibrating motor 8 is installed on the outer side of the inclined screen plate 1. The side plates 3 can prevent the material on the inclined screen plate 1 from overflowing from its sides during the process of the vibrating motor 8 driving the inclined screen plate 1 to vibrate and screen the material. A buffer support is fixed at the bottom of the inclined screen plate 1, providing running space when the inclined screen plate 1 vibrates. The two sides of the hopper 2 are supported by support rods 4. A cylinder 5 is installed on one side of the hopper 2, and a mounting plate 6 spanning the inclined screen plate 1 is provided at one end of the cylinder 5. A brush 7 is installed on the lower side of the mounting plate 6 via an adjustment component. During the vibration of the inclined screen plate 1 driven by the vibrating motor 8, the kernels are screened and fall below the inclined screen plate 1, while unhulled flax seeds move along the inclined screen plate 1 and are finally discharged from the lower end of the inclined screen plate 1. They can then be lifted again by an elevator to the hulling device for hulling. In use, the height of the brush 7 can be adjusted by operating the adjustment component. When cleaning the material on the inclined screen plate 1, the brush 7 is brought into contact with the top of the inclined screen plate 1. Then, the cylinder 5 is extended or retracted to move the mounting plate 6, thereby moving the brush 7 to clean the material stuck on the inclined screen plate 1. After cleaning, the operable adjustment component can move the brush 7 upward away from the inclined screen plate 1 to avoid the brush 7 affecting the screening of materials.

[0017] Example 2 Based on Example 1, a circulating sieving device for flaxseed hulling, in order to improve the support stability of the inclined sieve plate 1, preferably includes four buffer supports, each including a support leg 9 and a buffer spring 10 fixed to the support leg 9. The upper end of the buffer spring 10 is fixedly connected to the bottom of the inclined sieve plate 1. The buffer spring 10 can play a role in shock absorption and vibration isolation.

[0018] Based on Example 1, a circulating sieving device for flaxseed dehulling is provided. In order to adjust the height of the brush 7, the adjustment component preferably includes an L-shaped scraper 11 and a connecting plate 12 fixed to the lower side of the mounting plate 6. The L-shaped scraper 11 is located near the hopper 2. The connecting plate 12 is provided with a plurality of vertical adjustment holes 13. A plurality of threaded rods 14 corresponding to the vertical adjustment holes 13 are fixed on one side of the L-shaped scraper 11. The threaded rods 14 extend through the vertical adjustment holes 13 to one side of the connecting plate 12. A limit nut 140 is screwed onto one end of the threaded rod 14. After installation, the L-shaped scraper 11 is located on the side of the connecting plate 12 near the hopper 2, and the brush 7 is located on the lower side of the L-shaped scraper 11. In use, the installation height of the L-shaped scraper 11 in the vertical adjustment hole 13 can be adjusted by loosening the limiting nut 140. After adjustment, tighten the limiting nut 140 to secure the L-shaped scraper 11 to the connecting plate 12. With this setting, as the cylinder 5 drives the brush 7 to move, the L-shaped scraper 11 can penetrate below the hopper 2 to clean the material stuck on the inclined screen plate 1 directly below the hopper 2. As for the material falling on the L-shaped scraper 11 during the cleaning process, it can be cleaned manually after the screening device is stopped.

[0019] In this embodiment, a circulating sieving device for flaxseed dehulling is preferably designed to improve ease of use, with the mounting plate 6 and connecting plate 12 being an integrated molding structure.

[0020] Based on Example 1, a circulating screening device for flaxseed dehulling preferably includes a limiting rod 15 fixed to one side of the hopper 2 in order to limit the mounting plate 6; correspondingly, a limiting hole 16 is provided on the mounting plate 6, and the limiting rod 15 passes through the limiting hole 16 through the mounting plate 6.

[0021] Based on any of the above embodiments, in order to prevent the material falling through the hopper 2 from falling from the rear end of the inclined screen plate 1, a baffle 17 is preferably fixed at the high end of the inclined screen plate 1.

[0022] This utility model provides a circulating sieving device for flaxseed dehulling, comprising an inclined screen plate 1 and a hopper 2 located above the high end of the inclined screen plate 1. Side plates 3 are installed on opposite sides of the inclined screen plate 1, and a buffer support is fixed to the bottom of the inclined screen plate 1. The two sides of the hopper 2 are supported by support rods 4, and a cylinder 5 is installed on one side of the hopper 2. A mounting plate 6 spanning the inclined screen plate 1 is provided at one end of the cylinder 5. A brush 7 is provided on the lower side of the mounting plate 6 through an adjustment component, and a vibrating motor 8 is installed on the outer side of the inclined screen plate 1. In use, the dehulled flaxseeds fall onto the inclined screen plate 1 through the hopper 2. Then, as the vibrating motor 8 drives the inclined screen plate 1 to vibrate, the kernels are screened out and fall below the inclined screen plate 1. Unhulled flaxseeds move along the inclined screen plate 1 and are finally discharged from the lower end of the inclined screen plate 1, thereby achieving the sieving process of dehulled flaxseeds. When it is necessary to clean the kernels stuck on the inclined screen plate 1, the adjusting component can be operated to bring the bottom side of the brush 7 into contact with the inclined screen plate 1. Then, by controlling the extension and retraction of the cylinder 5, the brush 7 is moved back and forth to brush away the kernels stuck on the inclined screen plate 1. This can improve the cleaning effect and efficiency, and the operation is relatively safe. After cleaning, the adjusting component can be operated to detach the brush 7 from the inclined screen plate 1 and place it above the inclined screen plate 1.
