Description

Technical Field

[0001] This utility model belongs to the field of barley cleaning technology, specifically the adjustable screen of a barley cleaning and sorting integrated machine. Background Technology

[0002] Barley is an important cereal crop belonging to the genus *Hordeum* of the Poaceae family. It has multiple uses, including as a food source, feed, industrial raw material, and forage. Barley rice can be cooked into rice or porridge and is rich in dietary fiber, B vitamins, and minerals. Barley flour can be used to make bread, biscuits, noodles, and other products. Barley malt is a core ingredient in beer brewing, providing sugars and flavor compounds, and plays an important role in agricultural production and the food industry.

[0003] Cleaning and sorting barley before processing is a key step to ensure product quality, safety, and subsequent processing efficiency. Its purpose is not only to improve product purity and meet quality standards, but also to optimize processing efficiency and reduce production costs.

[0004] Through long-term use and observation, it was found that when using the barley washing and sorting integrated machine, due to the different sizes of barley grains, a single-size screen is difficult to meet the sorting needs of large, medium and small grains.

[0005] Therefore, this utility model provides an adjustable screen for a barley washing and sorting integrated machine. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, an adjustable screen for a barley washing and sorting integrated machine is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The adjustable screen of the barley washing and sorting integrated machine of this utility model includes a washing cylinder, characterized in that: a cylinder cover is slidably fitted on the top of the washing cylinder, multiple feed pipes are fixedly connected to the middle of the side wall of the cylinder cover, the feed pipes are connected to the washing cylinder, a water storage box is installed in the middle of the side wall of the cylinder cover, a water inlet pipe is connected to the top of the water storage box, a washing component is provided in the middle of the side wall of the water storage box, a screening component is provided in the middle of the inner side wall of the washing cylinder, the screening component is located below the feed pipe, a drain pipe is connected to the middle of the side wall of the washing cylinder, a vibration component is provided at the bottom of the washing cylinder, the screening component includes a first channel, the first channel is opened on the inner wall of the washing cylinder, multiple second channels are opened in the middle of the inner side wall of the washing cylinder, the second channels are connected to the first channels, a fixed screen plate is rotatably connected to the middle of the inner side wall of the second channel, and a movable screen plate is rotatably connected to the bottom of the fixed screen plate. The movable sieve plate and the fixed sieve plate are set up accordingly. Multiple fixed plates are fixed in the middle of the side wall of the washing cylinder. The fixed plates and the fixed sieve plates are set up accordingly. A first motor is assembled at the bottom of the fixed plate. A gear is fixedly connected to the output end of the first motor. The gear rotates on the top of the fixed plate. The gear meshes with a rack. The rack is inserted into the fixed sieve plate. This step can adjust the sieve hole size by setting the fixed sieve plate, the movable sieve plate, the first motor, the gear and the rack, so as to accurately match the "target particle size range" of different barley. This reduces the problem of the fixed sieve screen missing qualified grains due to the hole size being too large or trapping too many impurities due to the hole size being too small. Moreover, by using a multi-section adjustable sieve screen, the barley can be graded into "extra coarse grains, qualified grains and fine grains", reducing the number of unqualified grains entering subsequent processes, improving the sorting accuracy and ensuring the quality of subsequent processing. At the same time, by adjusting the sieve hole size according to the physical characteristics of impurities in the barley, small particle impurities can be separated in a targeted manner, and the separation efficiency of large particle impurities can be optimized, reducing the washing burden.

[0008] Preferably, the cleaning assembly includes a second motor mounted on the top of the water storage box. A movable box is fixedly connected to the output end of the second motor. The movable box and the water storage box are rotatably connected. Multiple water outlet pipes are connected to the bottom of the movable box. The water outlet pipes are inclined. This step, by setting the second motor, the movable box, and the water outlet pipes, allows the cleaning water to spread in a fan-shaped or spiral trajectory, covering every area inside the cleaning cylinder. This reduces the incomplete cleaning of barley in certain areas caused by the fixed spray range of the fixed nozzle, improving the uniformity and thoroughness of the cleaning. In addition, the rotating water flow not only cleans impurities but also forms a slight buffer layer, reducing the mutual friction of barley grains during the flow process, reducing husk wear and grain surface damage, thereby improving the pass rate of the finished barley.

[0009] Preferably, the vibration assembly includes a fixed base located below the washing cylinder. Multiple support springs are fixed to the top of the fixed base, and a connecting seat is fixed to the other end of each support spring. A positioning block is fixed to the top of the connecting seat. A positioning groove is provided at the bottom of the washing cylinder, and the positioning groove and positioning block are correspondingly arranged. This step, by setting up the fixed base, support springs, connecting seat, positioning block, and positioning groove, allows for continuous vibration of the fixed screen plate, enabling the barley grains to acquire "small upward kinetic energy." This reduces the adhesion between the grains and the inner wall of the equipment, and between the grains themselves, reducing their accumulation at the corners of the trough and the edges of the screen. This accelerates the flow of barley material, reduces accumulation and blockage, and improves processing efficiency.

[0010] Preferably, an elastic rope is fixed in the middle of the side wall of the water outlet pipe. The elastic rope is made of elastic material, and a ball is fixed to the other end of the elastic rope. This step of setting the elastic rope and the ball can break the adhesion structure of dirt such as mud, dust, and microorganisms on the surface of the barley through the vibration and impact force generated by rotation and knocking, making it easier to fall off. Combined with water flow rinsing, it can be more thorough, and combined with the screening component, it can remove impurities more efficiently.

[0011] Preferably, a dustproof cloth is provided in the middle of the inner sidewall of both the first and second channels. Multiple dustproof cloths are respectively covered outside the first and second channels. The dustproof cloths are made of elastic material. This step, by setting the dustproof cloths, can completely cover the gaps of the first or second channel, forming a flexible protective layer. This prevents barley grains, soil debris, weed fibers, etc. from getting stuck directly in the first or second channel during cleaning and sorting, thus blocking the accumulation of materials or impurities and ensuring the purity of barley processing.

[0012] Preferably, an observation window is provided in the middle of the side wall of the washing cylinder. The observation window is made of transparent material. This step allows direct observation of the washing and sorting status of the barley in the washing cylinder without waiting for sampling and testing after discharge, thus improving the real-time controllability of the washing and sorting quality.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The adjustable screen of the barley washing and sorting integrated machine of this utility model can adjust the screen hole size by setting a fixed screen plate, a movable screen plate, a first motor, gears and racks, so as to accurately match the "target particle size range" of different barley. This reduces the problem of the fixed screen missing qualified grains due to the hole size being too large or trapping too many impurities due to the hole size being too small. Moreover, through the multi-section adjustable screen, barley can be graded into "extra coarse grains, qualified grains, and fine grains", reducing the number of unqualified grains entering subsequent processes, improving sorting accuracy, and ensuring the quality of subsequent processing. At the same time, by adjusting the screen hole size according to the physical characteristics of impurities in barley, small particle impurities can be separated in a targeted manner, and the separation efficiency of large particle impurities can be optimized, reducing the washing burden.

[0015] 2. The adjustable screen of the barley washing and sorting integrated machine described in this utility model, through the setting of a second motor, a movable box and a water outlet pipe, can make the cleaning water spread in a fan-shaped or spiral trajectory, which can cover every area inside the washing cylinder, reduce the local incomplete cleaning of barley caused by the "fixed direct spray range" of the fixed nozzle, improve the uniformity and thoroughness of cleaning, and the rotating water flow can not only clean impurities, but also form a "slight buffer layer" to reduce the mutual friction of barley grains during the flow process, reduce the wear of barley husks and damage to the grain skin, thereby improving the qualification rate of finished barley.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 5 As shown in the figure, the adjustable screen of the barley washing and sorting integrated machine of this utility model includes a washing cylinder 1. The washing cylinder 1 is characterized by: a cylinder cover 11 slidingly fitted to the top; multiple feed pipes 12 fixedly connected to the middle of the side wall of the cylinder cover 11, communicating with the washing cylinder 1; a water storage box 13 installed in the middle of the side wall of the cylinder cover 11; a water inlet pipe 14 connected to the top of the water storage box 13; a washing component located in the middle of the side wall of the water storage box 13; a screening component located in the middle of the inner side wall of the washing cylinder 1, below the feed pipes 12; a drain pipe 15 connected to the middle of the side wall of the washing cylinder 1; and a vibration component located at the bottom of the washing cylinder 1, allowing the operator to adjust the position of the screening component. Adjust the size of the barley to be sorted, and then inject cleaning water into the water storage box 13 through the water inlet pipe 14. At this time, the cleaning water will be sprayed into the cleaning cylinder 1 through the cleaning component. Then, the staff will pour the barley to be cleaned and sorted into the cleaning cylinder 1 through multiple feed pipes 12. The cleaning water flowing out from the rotating cleaning component will clean the barley. At the same time, the screening component will sort the barley by size. During the screening process, the vibration component will continuously bounce the cleaning cylinder 1, causing the cleaning cylinder 1 to drive the screening component and the barley on the top of the screening component to vibrate simultaneously. After the cleaning and sorting is completed, the staff will discharge the wastewater from the cleaning cylinder 1 through the drain pipe 15.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the screening assembly includes a first channel 2, which is formed on the inner wall of the washing cylinder 1. Multiple second channels 21 are formed in the middle of the inner wall of the washing cylinder 1, and the second channels 21 communicate with the first channels 2. A fixed screen plate 22 is rotatably connected to the middle of the inner wall of the second channel 21. A movable screen plate 23 is rotatably connected to the bottom of the fixed screen plate 22. The movable screen plate 23 and the fixed screen plate 22 are correspondingly arranged. Multiple fixed plates 24 are fixed in the middle of the side wall of the washing cylinder 1, and the fixed plates 24 are correspondingly arranged with the fixed screen plates 22. A first motor 25 is mounted at the bottom of plate 24. A gear 26 is fixedly connected to the output end of the first motor 25. The gear 26 rotates on the top of the fixed plate 24. The gear 26 meshes with a rack 27, which is inserted into the fixed screen plate 22. When the operator inserts multiple fixed screen plates 22 and movable screen plates 23 along the inner wall of the washing cylinder 1, the fixed screen plates 22 will slide along the first channel 2 until they slide into the corresponding second channel 21. At this point, the fixed screen plates 22 will be inserted into the rack 27. Then, the first motor 25 is started, which drives the gear 26 to rotate. Because the gear 26 and rack 27 are meshed, the rotation of the gear 26 drives the rack 27 to rotate, and the rotation of the rack 27 drives the fixed screen plate 22 to rotate synchronously. At this time, the fixed screen plate 22 will rotate on top of the movable screen plate 23, thereby adjusting the screen hole size to achieve multi-stage sorting of barley. This step can adjust the screen hole size by setting the fixed screen plate 22, movable screen plate 23, first motor 25, gear 26 and rack 27 to accurately match the "target particle size range" of different barley, reducing the problem of the fixed screen missing qualified grains due to the hole size being too large or trapping too many impurities due to the hole size being too small. Moreover, through the multi-stage adjustable screen, barley can be graded into "extra coarse grains, qualified grains, and fine grains", reducing the number of unqualified grains entering subsequent processes, improving sorting accuracy, and ensuring the quality of subsequent processing. At the same time, adjusting the screen hole size according to the physical characteristics of impurities in barley can specifically separate small particles of impurities and optimize the separation efficiency of large particles of impurities, reducing the cleaning burden.

[0028] like Figures 1 to 5As shown, the cleaning assembly includes a second motor 3, which is mounted on the top of the water storage box 13. A movable box 31 is fixedly connected to the output end of the second motor 3, and the movable box 31 and the water storage box 13 are rotatably connected. Multiple water outlet pipes 32 are connected to the bottom of the movable box 31, and the water outlet pipes 32 are inclined. When the operator starts the second motor 3, the second motor 3 drives the movable box 31 to rotate on the inner wall of the water storage box 13. When the movable box 31 rotates, it drives the multiple water outlet pipes 32 to rotate simultaneously. At this time, the operator injects cleaning water into the water storage box 13 through the water inlet pipe 14. The cleaning water flows through the water storage box 13 and the movable box 31 towards... Inside the multiple water outlet pipes 32, the water is then sprayed into the cleaning cylinder 1 by the rotating water outlet pipes 32. This step, through the setting of the second motor 3, the movable box 31 and the water outlet pipes 32, allows the cleaning water to spread in a fan-shaped or spiral trajectory, covering every area inside the cleaning cylinder 1. This reduces the incomplete cleaning of barley in certain areas caused by the fixed spray range of the fixed nozzle, improving the uniformity and thoroughness of the cleaning. In addition, the rotating water flow can not only clean impurities, but also form a "slight buffer layer" to reduce the mutual friction of barley grains during the flow process, reduce husk wear and grain surface damage, thereby improving the qualification rate of the finished barley.

[0029] like Figures 1 to 4 As shown, the vibration assembly includes a fixed base 4, which is located below the washing cylinder 1. Multiple support springs 41 are fixed to the top of the fixed base 4, and a connecting base 42 is fixed to the other end of each support spring 41. A positioning block 43 is fixed to the top of the connecting base 42. A positioning groove 44 is provided at the bottom of the washing cylinder 1, and the positioning groove 44 and positioning block 43 are correspondingly arranged. The operator inserts the positioning groove 44 at the bottom of the washing cylinder 1 into the corresponding positioning block 43 at the top of the connecting base 42. When barley falls through the feed pipe 12 onto the top of the fixed screen plate 22 inside the washing cylinder 1, it will impact the fixed screen plate 22. 2. This causes the fixed screen plate 22 to drive the washing cylinder 1 to vibrate. At this time, the washing cylinder 1, under the counter-pushing action of multiple support springs 41, continuously shakes multiple fixed screen plates 22. This step, through the setting of fixed seat 4, support spring 41, connecting seat 42, positioning block 43 and positioning groove 44, can continuously vibrate the fixed screen plate 22, so that the barley grains can obtain "small upward kinetic energy", reduce the adsorption force between the grains and the inner wall of the equipment, and between the grains, reduce their accumulation at the corner of the material trough and the edge of the screen, accelerate the flow of barley material, reduce accumulation and blockage, and improve processing efficiency.

[0030] like Figure 5As shown, an elastic rope 5 is fixed in the middle of the side wall of the water outlet pipe 32. The elastic rope 5 is made of elastic material. A ball block 51 is fixed to the other end of the elastic rope 5. When the water outlet pipe 32 rotates, it will drive the elastic rope 5 to rotate inside the washing cylinder 1. When the elastic rope 5 rotates, it will pull the ball block 51 to move at the same time. At this time, multiple balls 51 will continuously hit the inner wall of the washing cylinder 1, thereby vibrating the washing cylinder 1. This step of setting up the elastic rope 5 and the ball block 51 can destroy the adhesion structure of dirt, dust, microorganisms and other dirt on the surface of the barley through the vibration and impact force generated by the rotation and hitting, making it easier to fall off. Combined with water flow rinsing, it is more thorough. Combined with the screening component, it can remove impurities more efficiently.

[0031] like Figure 5 As shown, dustproof cloths 6 are provided in the middle of the inner sidewalls of the first channel 2 and the second channel 21. Multiple dustproof cloths 6 are respectively covered on the outside of the first channel 2 and the second channel 21. The dustproof cloths 6 are made of elastic material. This step can completely cover the gaps of the first channel 2 or the second channel 21 by setting the dustproof cloths 6, forming a flexible protective layer to prevent barley grains, soil debris, weed fibers, etc. from getting stuck directly in the first channel 2 or the second channel 21 during cleaning and sorting, blocking the accumulation of materials or impurities and ensuring the purity of barley processing.

[0032] like Figure 1 As shown, an observation window 7 is provided in the middle of the side wall of the washing cylinder 1. The observation window 7 is made of transparent material. By setting the observation window 7, the washing and sorting status of the barley in the washing cylinder 1 can be directly viewed without waiting for sampling and testing after discharge, thus improving the real-time controllability of the washing and sorting quality.

[0033] Working principle: The operator adjusts the position of the screening component to suit the size of the barley to be sorted. Cleaning water is then injected into the water storage box 13 through the water inlet pipe 14. This cleaning water is sprayed into the washing cylinder 1 through the washing component. The operator then pours the barley to be cleaned and sorted into the washing cylinder 1 through multiple feed pipes 12. The cleaning water flowing out from the rotating washing component washes the barley, while the screening component sorts the barley by size. During the screening process, the vibrating component continuously bounces the washing cylinder 1, causing the washing cylinder 1 to move the screening component and the barley on top of the screening component simultaneously. After vibration and cleaning / sorting, the wastewater is discharged from the cleaning cylinder 1 through the drain pipe 15. The worker inserts multiple fixed screen plates 22 and movable screen plates 23 along the inner wall of the cleaning cylinder 1. At this time, the fixed screen plates 22 slide along the first channel 2 until they slide into the corresponding second channel 21. The fixed screen plates 22 then engage with the rack 27. The first motor 25 is then started, driving the gear 26 to rotate. Because the gear 26 and rack 27 are meshed, the rotation of the gear 26 drives the rack 27 to rotate, and the rotation of the rack 27 drives... The fixed sieve plate 22 rotates synchronously, and at this time, the fixed sieve plate 22 will rotate on top of the movable sieve plate 23 to adjust the sieve holes of the appropriate size, so that the barley can be sorted in multiple stages. The staff starts the second motor 3, which drives the movable box 31 to rotate on the inner wall of the water storage box 13. When the movable box 31 rotates, it will drive multiple water outlet pipes 32 to rotate simultaneously. At this time, the staff injects cleaning water into the water storage box 13 through the water inlet pipe 14. The cleaning water will flow through the water storage box 13 and the movable box 31 into the multiple water outlet pipes 32, and then be sprayed into the cleaning cylinder 1 by the rotating water outlet pipes 32. The positioning groove 44 at the bottom of the washing cylinder 1 corresponds to the positioning block 43 at the top of the connecting seat 42. When the barley falls on the top of the fixed screen plate 22 inside the washing cylinder 1 through the feed pipe 12, it will impact the fixed screen plate 22, causing the fixed screen plate 22 to drive the washing cylinder 1 to vibrate. At this time, under the counter-pushing action of multiple support springs 41, the washing cylinder 1 will continuously shake multiple fixed screen plates 22. When the water outlet pipe 32 rotates, it will drive the elastic rope 5 to rotate inside the washing cylinder 1. When the elastic rope 5 rotates, it will pull the ball block 51 to move at the same time. At this time, multiple ball blocks 51 will continuously hit the inner wall of the washing cylinder 1, thereby vibrating the washing cylinder 1.
