Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] See Figure 1 Figure 2 and Figure 3 This utility model provides a grinding equipment for the production and processing of highland barley flour, comprising: a support frame 4, a feeding bin 5 disposed on the top of the support frame 4, a support plate 6 disposed on the side wall of the support frame 4, the feeding bin 5 having a lower opening 8 and an upper opening 7, the lower opening 8 being used for material discharge, the upper opening 7 being connected to the side wall of a crushing bin 9, the crushing bin 9 being at least partially located within the feeding bin 5, the crushing bin 9 being provided with a crushing component 1 and a filter screen 10, with the filter screen 10 located below the crushing component 1, a feeding bin 11 disposed at the top of the crushing bin 9, and a support plate 6. A motor 12 is installed on the 6, and a first pulley 13 is installed on the rotating shaft of the motor 12. One end of the crushing component 1 that extends out of the crushing chamber 9 is connected to a second pulley 14. The second pulley 14 is connected to the first pulley 13 by a belt. The other end of the crushing component 1 that extends out of the crushing chamber 9 is connected to a transmission component 2. The transmission component 2 is installed in the feeding chamber 5. The scraping component 3 is installed in the feeding chamber 5. The scraping component 3 is connected to the transmission component 2 and the crushing chamber 9 respectively. The scraping component 3 is used to scrape off the material accumulated at the bottom of the filter holes of the filter screen 10.

[0032] The crushing chamber 9 is a frame structure with openings at both the top and bottom. After being crushed, the bare barley grains enter the feeding chamber 5 through the filter screen 10 and the opening at the bottom of the crushing chamber 9, and are then discharged through the lower opening 8. The motor 12 rotates, driving the crushing component 1 to rotate. The crushing component 1 then transmits the power generated by its rotation to the scraping component 3 via the transmission component 2. Driven by the power, the scraping component 3 cleans the bottom of the filter screen 10's mesh, preventing the filter screen 10 from becoming clogged.

[0033] Specifically, bare barley grains are fed into the feed hopper 11 and, due to gravity, enter the crushing hopper 9. The motor 12 is started, driving the first pulley 13 on its rotating shaft, which is connected to the second pulley 14 via a belt, thereby rotating the crushing assembly 1 within the crushing hopper 9 to crush the bare barley grains. The crushed barley powder is filtered through a filter screen 10 located below the crushing assembly 1. Barley powder meeting the particle size requirements falls through the filter holes of the filter screen 10 into the discharge hopper 5 and is discharged from the lower opening 8 of the discharge hopper 5. Barley powder not meeting the particle size requirements continues to be crushed by the crushing assembly 1 within the crushing hopper 9. A transmission assembly 2, located at the other end of the crushing assembly 1, operates synchronously, driving a scraping assembly 3 located within the discharge hopper 5. The scraping assembly 3 is connected to the crushing hopper 9 and moves relative to the bottom of the filter screen 10, continuously scraping away material accumulated at the bottom of the filter holes to prevent clogging and ensure screening efficiency.

[0034] In some embodiments, the end of the crushing component 1 away from the motor 12 extends out of the crushing chamber 9 and is connected to the third pulley 15, the transmission component 2 is connected to the fourth pulley 16, and the fourth pulley 16 is belt-connected to the third pulley 15.

[0035] Driven by motor 12, the first pulley 13 drives the second pulley 14 to rotate via a belt, thereby driving the crushing component 1 to crush the bare barley grains. Simultaneously, the end of the crushing component 1 furthest from motor 12 extends out of the crushing chamber 9 and connects to the third pulley 15. The third pulley 15 is connected to the fourth pulley 16 via a belt, further transmitting power to the transmission component 2, and then to the scraping component 3. This ensures that the scraping component 3 operates synchronously with the crushing component 1, achieving coordinated crushing of the bare barley grains and cleaning of the filter screen 10. Furthermore, all operations share a single motor 12, saving costs.

[0036] See Figure 6 In some embodiments, the transmission assembly 2 includes a first rotating rod 201, a second rotating rod 202, a first transmission wheel 203, and a second transmission wheel 204. The first rotating rod 201 and the second rotating rod 202 are rotatably disposed in the feeding bin 5. The first rotating rod is provided with the first transmission wheel 203, and the second rotating rod 202 is provided with the second transmission wheel 204. The first transmission wheel 203 and the second transmission wheel 204 are connected by a belt. One end of the first rotating rod 201 that extends out of the feeding bin 5 is connected to the fourth belt pulley 16. The second rotating rod 202 is connected to the scraping assembly 3 through the rotating disk 17.

[0037] When the fourth pulley 16 receives power from the third pulley 15, it drives the first rotating rod 201 to rotate within the feeding hopper 5. The first transmission wheel 203 on the first rotating rod 201 is connected to the second transmission wheel 204 via a belt, thereby driving the second rotating rod 202 to rotate synchronously. The second rotating rod 202 is connected to the scraping assembly 3 via the rotating disk 17, thereby cleaning the barley flour accumulated below the filter holes, ensuring the filter screen 10 is unobstructed, and improving the screening continuity and crushing efficiency of the bare barley grains.

[0038] See Figure 5 In some embodiments, the scraping assembly 3 includes a slide rail 301, a slider 302, a connecting rod 303, and a scraping rod 304. The slide rail 301 is disposed on both sides of the bottom end of the crushing chamber 9. The sliders 302 are slidably disposed on the slide rail 301. The sidewalls of the two sliders 302 are hinged to one end of the connecting rod 303, and the other end of the connecting rod 303 is hinged to the outer sidewall of the rotating disk 17. The scraping rod 304 is disposed between the two sliders 302.

[0039] When the rotating disk 17 rotates, the connecting rod 303 pushes the two sliders 302 to reciprocate on the slide rail 301, which in turn drives the scraping rod 304 connected between the two sliders 302 to move, so that it reciprocates along the bottom of the filter hole of the filter screen 10 to remove the blocked barley powder in time, prevent the screen hole from being blocked, and ensure that the crushed barley powder falls smoothly into the feed hopper 5 and is discharged from the lower opening 8.

[0040] See Figure 3 In some embodiments, the crushing assembly 1 includes a drive rod 101, a connecting plate 102, and a crushing head 103. The drive rod 101 is rotatably disposed in the crushing chamber 9, and both ends of the drive rod 101 extend out of the crushing chamber 9 and are respectively connected to the second pulley 14 and the third pulley 15. The connecting plates 102 are spaced apart on the drive rod 101, and a plurality of crushing heads 103 are circumferentially disposed between any two adjacent connecting plates 102.

[0041] The drive rod 101 is rotatably mounted inside the crushing chamber 9, with its two ends extending out of the crushing chamber 9 and connected to the second pulley 14 and the third pulley 15, respectively, to receive transmission power from the motor 12. When the drive rod 101 rotates, it drives the crushing head 103 to rotate at high speed, performing efficient shearing and impact crushing on the bare barley grains entering the crushing chamber 9 from the feed hopper 11. The crushed barley powder passes downward through the filter screen 10 under the action of gravity, while the bare barley grains that do not meet the standards continue to remain in the crushing chamber 9 for cyclic crushing until they meet the particle size requirements.

[0042] See Figure 7 In some embodiments, a reinforcing block 18 is provided at the top of the scraper bar 304.

[0043] The reinforcing block 18 enhances the structural strength and durability of the scraper bar 304. It can resist the mechanical stress during long-term reciprocating motion of the scraper bar 304, preventing deformation or breakage.

[0044] In some embodiments, a plurality of spherical protrusions 19 are uniformly provided on the reinforcing block 18.

[0045] As the scraper bar 304 moves along the bottom of the filter screen 10, these spherical protrusions 19 can apply local pressure and slight vibration to the area around the filter holes, which helps to loosen the fine powder material adhering to the bottom of the filter screen 10 and improve the scraping efficiency.

[0046] See Figure 4 In some embodiments, limit baffles 20 are symmetrically arranged inside the crushing chamber 9.

[0047] The limiting baffle 20 is used to limit the filter screen 10 when it is installed in the crushing chamber 9, thereby improving the stability of the filter screen 10 in the crushing chamber 9.

[0048] In some embodiments, inclined plates 21 are provided on the two opposite side walls at the bottom end of the crushing chamber 9.

[0049] Inclined plates 21 are installed on the two opposite side walls at the bottom of the grinding chamber 9. Under the action of gravity, the ground barley flour slides down the inclined plates 21 towards the central area, preventing the barley flour from accumulating and remaining in the corners of the grinding chamber 9. The inclined plates 21 can guide the ground barley flour to flow to the central area of ​​the filter screen 10, improving the sieving efficiency.

[0050] See Figure 3 In some embodiments, one end of the feed bin 11 is hinged to one side of the top of the crushing bin 9, and the other end of the feed bin 11 is connected to the other side of the top of the crushing bin 9 by a quick-release bolt 22.

[0051] One end of the feed hopper 11 is hinged to one side of the top of the crushing chamber 9, and the other end is fixed to the other side of the top of the crushing chamber 9 by a quick-release bolt 22, allowing the feed hopper 11 to be opened and closed quickly. During equipment maintenance, replacement of the crushing head 103, or cleaning of internal accumulated material, the feed hopper 11 can be flipped open simply by removing the quick-release bolt 22, facilitating a thorough cleaning and inspection of the crushing assembly 1, filter screen 10, and the interior of the crushing chamber 9, significantly improving the maintainability and ease of operation of the equipment. When the feed hopper 11 is connected to the crushing chamber 9, sealing gaskets, such as rubber gaskets, can be installed on the side walls where they contact each other to reduce the splashing of barley flour from the connection point between the feed hopper 11 and the crushing chamber 9.

[0052] It should be noted that the first rotating rod 201, the second rotating rod 202, and the drive rod 101 mentioned above are all equipped with rotating seats to ensure stability during rotation. The motor 12 and the quick-release bolt 22 are parts known to those skilled in the art, and this application has not made any improvements to them, so they will not be described in detail.

[0053] Work process

[0054] Barley grains are fed into the feed hopper 11 and then into the crushing hopper 9. The motor 12 is started, and its rotation drives the first pulley 13 to rotate. Through belt transmission, the second pulley 14 is driven to rotate, which in turn drives the drive rod 101 to rotate. The connecting disc 102 on the drive rod 101 and the circumferentially arranged crushing head 103 crush the barley grains. The crushed barley flour moves downward under gravity and is sieved through the filter screen 10. The qualified barley flour falls through the filter screen 10, is guided by the inclined plate, enters the discharge hopper 5, and is discharged from the lower opening 8 of the discharge hopper 5.

[0055] Simultaneously, the end of the drive rod 101 away from the motor 12 drives the third pulley 15 to rotate, which in turn drives the fourth pulley 16 to rotate via the belt. The fourth pulley 16 drives the first rotating rod 201 to rotate. The first rotating rod 201 drives the second transmission wheel 204 and the second rotating rod 202 to rotate synchronously via the first transmission wheel 203 and the belt. The second rotating rod 202 drives the connecting rod 303 to move via the rotating disk 17. The two ends of the connecting rod 303 are respectively hinged to the outer wall of the rotating disk 17 and the slider 302, so that the slider 302 slides back and forth on the slide rails 301 on both sides of the bottom of the crushing chamber 9. The scraping rod 304 between the two sliders 302 moves back and forth accordingly to scrape off the material accumulated at the bottom of the filter holes of the filter screen 10.

[0056] This application uses a motor 12 to drive a crushing assembly 1 to crush barley, and a filter screen 10 for sieving. A scraping assembly 3, extended from the crushing assembly 1 and driven by a pulley and transmission assembly 2, drives a scraper rod 304 to reciprocate on a slide rail 301, continuously removing material accumulated at the bottom of the filter screen 10's filter holes. This effectively prevents clogging of the screen holes and ensures smooth discharge. This improves the barley flour processing efficiency, flour quality, and equipment operational stability.
