Description

Technical Field

[0001] This utility model belongs to the field of barley processing technology, specifically a dustproof and noise-reducing feed hopper for a barley crusher. Background Technology

[0002] Barley is a type of cereal grain belonging to the Poaceae family. It is an important food crop and a primary raw material for brewing beer and feeding livestock.

[0003] Barley crushers are important equipment in beer brewing and feed processing. After crushing, the starch and other substances inside the barley grains can come into contact with hot water over a larger area, thus being saccharified more efficiently. The crusher usually consists of two metal rollers rotating in opposite directions. The barley grains pass through the gap between the two rollers, and the two rollers generate a certain shearing force to flatten the barley husks.

[0004] When barley enters the hopper, the barley will generate dust due to friction and high-speed collision between the grains. At the same time, due to airflow disturbance in the crushing chamber, the dust will diffuse back into the hopper through the connection gap between the feed hopper and the crusher. The dust is easy to overflow from the top opening of the feed hopper, resulting in dust accumulation on the surface of the equipment, requiring frequent cleaning and causing pollution to the production environment.

[0005] Therefore, this utility model provides a dustproof and noise-reducing feed hopper for a barley crusher. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5 As shown in the embodiment of this utility model, the dustproof and noise-reducing feeding hopper of the barley crusher includes a hopper body 1; a discharge seat 11 is fixedly connected to the bottom of the hopper body 1; a connecting box 16 is fixedly connected to the side wall of the hopper body 1; a feeding port 12 is opened at the top of the hopper body 1; the connecting box 16 is located on the side near the feeding port 12; a vacuum cleaner 13 is installed on the outer side wall of the hopper body 1; a vacuum cleaner pipe 14 is fixedly connected to the top of the vacuum cleaner 13; an annular pipe 15 is connected to the end of the vacuum cleaner pipe 14; a plurality of connecting pipes 19 are fixedly connected to the middle of the annular pipe 15; the ends of the plurality of connecting pipes 19 are connected to the outer side wall of the connecting box 16; The inner wall of the receiving box 16 has several dust suction holes 17; a filter plate 18 is fixedly connected to the inner wall of the receiving box 16; an interception component 2 is installed on the inner wall of the hopper 1; during operation, the hopper 1 is connected to the top of the crusher through the discharge seat 11, and the dust collector 13 is turned on. The negative pressure airflow generated inside the dust collector 13 draws in external air through multiple sets of dust suction holes 17, and transports the barley into the hopper 1 through the feed inlet 12. The dust generated when the barley is fed is drawn into the receiving box 16 through the negative pressure airflow and several dust suction holes 17, and the dust generated during feeding is adsorbed in real time. Large particles are intercepted by the filter plate 18, and airflow from various angles is evenly introduced into the annular pipe 15 through several connecting pipes 19. Dust is collected in the dust collector 13 through the dust suction pipe 14. The barley enters the crusher through the discharge seat 11. The uniform negative pressure airflow of the above structure can absorb and collect dust in time when the barley is fed down, reducing the spread of dust to the top of the hopper 1 or the surrounding environment with the flow of materials, reducing the dust from adhering to the inner wall of the hopper 1 and causing it to be raised again with the flow of materials, reducing the recurrence of dust pollution, thereby reducing dust accumulation and environmental pollution.

[0025] like Figure 2 and Figure 3As shown, the interception component 2 includes a fixed shaft 21; the fixed shaft 21 is fixedly connected to the inner wall of the bucket body 1; multiple baffles 22 are rotatably connected to the middle of the fixed shaft 21; a first hinge seat 23 is fixedly connected to the middle of the baffle 22; multiple second hinge seats 27 are fixedly connected to the inner wall of the bucket body 1; a positioning rod 25 is rotatably connected to the middle of the second hinge seat 27; an adjusting rod 24 is slidably connected to the middle of the positioning rod 25; the end of the adjusting rod 24 is hinged to the middle of the baffle 22; a first spring 26 is fixedly connected to the end of the adjusting rod 24; the end of the first spring 26 is fixedly connected to one end inside the positioning rod 25; during operation, when barley enters the bucket body 1, it first falls onto the surface of multiple baffles 22, and the falling barley puts pressure on the baffles 22, causing them to rotate downwards at the middle of the fixed shaft 21. At this time, the adjusting rod 24 slides into the positioning rod 25 as the baffle 22 rotates. The adjusting rod 24 rotates in the middle of the first hinge seat 23, and the first spring 26 elastically contracts. After the multiple baffles 22 rotate downward, the barley falls from between the multiple baffles 22 into the bottom of the hopper 1. After the barley is conveyed, the baffles 22, which are no longer under pressure, rotate upward as the first spring 26 elastically resets, blocking the dust generated during the crushing of the barley from being discharged. Through the above structure, a large amount of dust generated by the violent impact of the material during the crushing of barley can be reduced, the dust generated inside the crusher can be isolated, the dust generated during crushing can be reduced from spreading to the outside, and a stable buffer platform can be provided for the barley, effectively slowing down the falling speed of the material, thereby helping to increase the noise reduction effect.

[0026] like Figure 2 and Figure 5 As shown, multiple fixing plates 3 are fixed to the inner wall of the hopper 1; the multiple fixing plates 3 are located at the top of the discharge seat 11; multiple hook and loop fasteners 31 are fixed to the inner wall of the hopper 1; the multiple hook and loop fasteners 31 are equidistantly arranged; a hook and loop fastener female surface 32 is installed in the middle of the hook and loop fasteners 31; a sound-absorbing plate 33 is fixed to the middle of the hook and loop fastener female surface 32; during operation, the sound-absorbing plate 33 is placed on the inner side of the bottom of the hopper 1, the hook and loop fastener female surface 32 and the hook and loop fasteners 31 are attached and fixed by hook and loop; when barley is fed through the baffle 22, the barley falls onto the surface of the sound-absorbing plate 33, and the sound-absorbing plate 33 buffers the barley, reducing the noise generated by the impact of the material during feeding. The above structure can absorb the impact and friction generated by the barley falling against the inner wall of the hopper 1, absorb the noise generated by the impact of the barley, and when the sound-absorbing plate 33 is damaged by friction after long-term use, the sound-absorbing plate 33 can be quickly disassembled and replaced for easy maintenance.

[0027] like Figure 1 and Figure 4As shown, a connecting seat 4 is fixedly connected to the top of the bucket body 1; the connecting seat 4 is positioned at the corresponding feed inlet 12; an installation groove 41 is provided in the middle of the connecting seat 4; an installation plate 42 is installed in the middle of the installation groove 41; a splash guard 44 is fixedly connected to the top of the installation plate 42; multiple fixing grooves 43 are provided in the middle of the installation plate 42; multiple fixing rods 45 are slidably connected to the middle of the connecting seat 4; an adjustment handle 47 is fixedly connected to the end of the fixing rod 45; a second spring 46 is fixedly connected between the adjustment handle 47 and the connecting seat 4; the end of the fixing rod 45 corresponds to the fixing groove 43; during operation, the bottom mounting plate 42 of the splash guard 44 is placed in the middle of the installation groove 41, the bottom of the mounting plate 42 applies pressure to the fixing rod 45, causing it to slide outward in the middle of the connecting seat 4, the second spring 46 is elastically stretched, and the rod rotates. When the fixing rod 45 and the fixing groove 43 are aligned, the fixing rod 45, which is not under pressure, is elastically contracted by the second spring 46 and reset. The end of the fixing rod 45 enters the corresponding fixing groove 43, and the fixing groove 43 is fixed to the middle of the connecting seat 4 by the fixing rod 45, thereby installing the splash guard 44 on the top of the hopper 1. The splash guard 44 blocks the splashing generated when barley is fed. Different sizes of splash guard 44 can be replaced according to actual needs. The above structure can expand the feeding receiving area, effectively reduce the splashing of barley to the outside when it enters the hopper 1, reduce the waste of raw materials, and allow the splash guard 44 to be quickly replaced. Different sizes of splash guard 44 can be replaced according to actual needs, improving the versatility of the splash guard 44.

[0028] like Figure 1 As shown, sound insulation cotton 5 is fixedly connected to the middle of the bucket body 1; the sound insulation cotton 5 is fixedly connected to the outer wall of the bucket body 1; when barley is fed during operation, the sound insulation cotton 5 absorbs the sound generated by the collision of materials inside the bucket body 1. Through the above structure, the sound insulation cotton 5 can absorb some noise and effectively reduce the transmission of noise to the outside.

[0029] like Figure 1 As shown, a viewing panel 6 is fixed to the side wall of the hopper 1; the viewing panel 6 is transparent; during operation, the barley feeding situation inside the hopper 1 can be directly observed through the viewing panel 6. Through the above structure, the operator can observe the barley inside the hopper 1 in a timely manner, and can promptly detect and maintain any damage to the equipment inside the hopper 1.

[0030] like Figure 3 As shown, the baffle 22 is made of flexible material. When the barley comes into contact with the baffle 22 during operation, the flexible material buffers the impact force generated when the barley grains fall. The above structure can reduce the noise generated by the hard contact between the barley and the baffle 22 and reduce the wear of the baffle 22 over a long period of time.

[0031] During operation, the hopper 1 is connected to the top of the crusher via the discharge seat 11. The vacuum cleaner 13 is activated, and the negative pressure airflow generated inside the vacuum cleaner 13 draws in external air through multiple suction holes 17. The barley is then transported into the hopper 1 through the feed inlet 12. Dust generated during barley feeding is drawn into the connecting box 16 through several suction holes 17 by the negative pressure airflow, where it is absorbed in real time. Large particles are intercepted by the filter plate 18, and airflow from various angles is evenly distributed into the annular pipe 15 via several connecting pipes 19. Dust is collected inside the vacuum cleaner 13 via the suction pipe 14. The barley enters the crusher through the discharge seat 11. When the barley enters the hopper 1, it first falls onto the surface of multiple baffles 22. The falling barley presses against the baffles 22, causing them to rotate downwards in the middle of the fixed shaft 21. At this time, the adjusting rod 24 slides into the positioning rod 25 as the baffles 22 rotate. The adjusting rod 24 then... The hinge seat 23 rotates in the middle, the first spring 26 elastically contracts, and after the multiple baffles 22 rotate downwards, the barley falls from between the multiple baffles 22 into the bottom of the hopper 1. After the barley is conveyed, the baffles 22, no longer under pressure, elastically return to their original position with the first spring 26 and rotate upwards to prevent the dust generated during the barley crushing from being discharged. The sound-absorbing plate 33 is placed on the inner side of the bottom of the hopper 1, and the Velcro female side 32 and the Velcro male side 31 are attached and fixed by hooks. When the barley is fed through the baffles 22, the barley falls... The sound-absorbing plate 33 buffers the barley, reducing noise generated by material impact during feeding. The bottom mounting plate 42 of the splash guard 44 is placed in the middle of the mounting groove 41. The bottom of the mounting plate 42 applies pressure to the fixing rod 45, causing it to slide outwards in the middle of the connecting seat 4. The second spring 46 elastically stretches. Rotating the mounting plate 42, when the fixing rod 45 coincides with the fixing groove 43, the unpressurized fixing rod 45 is elastically contracted by the second spring 46 and resets. The end of the fixing rod 45 enters the corresponding fixing groove. In the fixed groove 43, the fixed groove 43 is fixed to the middle of the connecting seat 4 by the fixed rod 45, so that the splash guard 44 is installed on the top of the bucket body 1. The splash guard 44 blocks the splash generated when barley is fed. Different sizes of splash guard 44 can be replaced according to actual needs. When barley is fed, the sound insulation cotton 5 absorbs the sound generated by the collision of materials inside the bucket body 1. The barley feeding situation inside the bucket body 1 can be directly observed through the visual panel 6. When the barley comes into contact with the baffle 22, the flexible material buffers the impact force generated when the barley particles fall.
