[0002] After the grains are removed from the husk and impurities, they are generally crushed using a crusher. Grain crushing is the process of grinding the grains into coarse particles larger than flour or finer. Grain crushing can increase the fiber content of food, which is very important for improving the nutritional value of food.

[0003] Existing grain crushers have the following deficiencies: The distance between the two crushing rollers in the crusher cannot be adaptively adjusted according to the size of the grains. When the grains are small, if the distance between the crushing rollers is larger than the grains, the grains will fall directly from between the crushing rollers and cannot be crushed. It is not convenient to crush the same grain into particles of different sizes, and it is impossible to meet the crushing requirements of the same grain with different particle sizes.

DETAILED DESCRIPTION

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] The present invention provides the following preferred embodiments: Embodiment 1, as Figure 1-Figure 10 As shown, a grain adaptive crusher includes a bracket 14, a crushing box 11 is installed in the middle of the bracket 14, the bracket 14 is used to support the crushing box 11, a feed port 12 is installed at the top of the crushing box 11, and a discharge port 13 is installed at the bottom of the crushing box 11. The feed port 12 is used to feed grains to be crushed, and the discharge port 13 is used to discharge crushed grains. It also includes a crushing mechanism, a discharge mechanism and an anti-blocking mechanism; The material unloading mechanism includes a rotating assembly, two guide plates 15 and two rotating shafts 16. The two rotating shafts 16 are symmetrically arranged on both sides of the crushing box 11. One end of each guide plate 15 is fixedly mounted on the surface of a rotating shaft 16. The rotating assembly is installed between the crushing box 11 and the two rotating shafts 16. The rotating assembly can drive the two rotating shafts 16 to rotate, thereby driving the two guide plates 15 to rotate, so that the opening size between the two guide plates 15 can be adjusted. At the same time, the inclined guide plates 15 can also guide the grains, so that the grains can fall accurately between the two crushing rollers 36. The crushing mechanism includes a first transmission assembly, a telescopic assembly, a driving assembly, two crushing rollers 36, two first slides 38 and four first sliders 37. The two first slides 38 are symmetrically arranged at both ends of the crushing box 11. Each two first sliders 37 are slidably arranged inside a first slide 38. Specifically, two fixed rods 66 are fixedly installed inside each first slide 38. Each first slider 37 is sleeved on the two fixed rods 66 and is slidably connected to the fixed rods 66 through a sliding bearing. The two crushing rollers 36 are symmetrically arranged inside the crushing box 11 and are located below the two guide plates 15. Specifically, each crushing roller 36 is provided with crushing teeth, and the crushing teeth on the two crushing rollers 36 are meshed with each other. The shafts on both sides of each crushing roller 36 are rotatably arranged on the two first sliders 37 at both ends. The driving assembly is installed between the two first sliders 37 on the same side. The driving assembly can drive the two crushing rollers 36 to rotate, thereby achieving the crushing of grains. The telescopic assembly is installed on the two first sliders 37 on the other side. The first transmission assembly is installed between the telescopic assembly and the rotating assembly. When the rotating assembly is working to adjust the angles of the two guide plates 15, the telescopic assembly can be driven to work through the first transmission assembly, thereby adjusting the distance between the two crushing rollers 36; When the opening between the two guide plates 15 increases, the spacing between the two crushing rollers 36 increases synchronously, which meets the crushing requirements of larger grains. At the same time, the opening between the two guide plates 15 is large, which is more conducive to the discharge of large grains, avoiding the influence of small opening on efficiency and speed, thereby improving the crushing efficiency of large grains. When the opening between the two guide plates 15 becomes smaller, the distance between the two crushing rollers 36 becomes smaller synchronously, so as to adapt to the crushing of grains with smaller particles, effectively crush small grains, and avoid the situation where grains fall directly from between the two crushing rollers 36; For the same kind of grain, by adjusting the distance between the two crushing rollers 36, the crushing force of the crushing roller 36 on the grain can be adjusted, so that the same kind of grain can be crushed into particles of different sizes, which can meet the crushing requirements of the same kind of grain with different particle sizes; The anti-blocking mechanism includes two driving rods 56, two swinging assemblies, two second transmission assemblies, four second sliders 52, four second slides 51, a plurality of knocking rods 54 and a plurality of rubber heads 55. Each of the two second slides 51 is symmetrically arranged on one side of the crushing box 11. Each of the second sliders 52 is slidably arranged inside a second slide 51. Both ends of each driving rod 56 are rotatably arranged on the two second sliders 52. One end of the plurality of knocking rods 54 is fixedly arranged on the two knocking rods 54. Each rubber head 55 is fixedly arranged on one end of a knocking rod 54 away from the driving rod 56. Each swinging assembly is installed at one end of a driving rod 56. Each second transmission assembly is installed between a swinging assembly and a crushing roller 36. When the crushing roller 36 rotates to crush the grains, the second transmission assembly can drive the swing assembly to work, thereby driving the driving rod 56 to swing, so that the multiple rubber heads 55 on the driving rod 56 can continuously knock the crushing roller 36, knocking off the grains accumulated on the crushing roller 36, thereby cleaning the grains adhered to the crushing roller 36, which is beneficial to improving the crushing accuracy and crushing effect.

[0037] like Figure 1-Figure 10 As shown, the rotating assembly includes a first motor 17, two first sprockets 18, two second sprockets 19, two gears 20 and two chains 21, one end of each rotating shaft 16 extends out of the crushing box 11 and is fixedly connected to a first sprocket 18, the two second sprockets 19 are rotatably arranged on the surface of the crushing box 11, each chain 21 is sleeved on a first sprocket 18 and a second sprocket 19, one side of each second sprocket 19 is coaxially fixed with a gear 20, the two gears 20 are meshed with each other, the first motor 17 is fixedly installed on the crushing box 11, and the output end of the first motor 17 is fixedly connected to one end of one of the rotating shafts 16 away from the first sprocket 18; When the opening size of the two guide plates 15 needs to be adjusted, the first motor 17 is controlled to work, and the first motor 17 can drive the rotating shaft 16 to rotate. At this time, the rotating shaft 16 can drive the first sprocket 18 to rotate. Under the action of the chain 21, when the first sprocket 18 rotates, it can drive the second sprocket 19 to rotate synchronously. At the same time, the second sprocket 19 and the gear 20 are coaxial and fixedly connected. Therefore, when the second sprocket 19 rotates, it can drive the gear 20 to rotate. Since the two gears 20 are meshed with each other, when one gear 20 rotates, it can drive the other gear 20 to rotate in the opposite direction. Therefore, the two guide plates 15 on both sides can be rotated, so that the opening between the two guide plates 15 can be increased or decreased.

[0038] like Figure 1-Figure 10As shown, the driving assembly includes a rotating rod 44, a second motor 49, two first bevel gears 40, two second bevel gears 41, two rotating sleeves 42, two fixed sleeves 43, two first connecting plates 48, two mounting plates 47, a plurality of limit blocks 46 and a plurality of limit slots 45; Two mounting plates 47 are symmetrically fixed on both sides of one end of the crushing box 11, the rotating rod 44 is rotatably arranged between the two mounting plates 47, the second motor 49 is fixedly installed on one side of a mounting plate 47, the output end of the second motor 49 is fixedly connected to one end of the rotating rod 44, the two rotating sleeves 42 are sleeved on the rotating rod 44, each fixed sleeve 43 is rotatably arranged on the outside of a rotating sleeve 42 through a bearing, the bottom end of each fixed sleeve 43 is fixedly connected to a first connecting plate 48, and each first connecting plate 48 is fixed to a first slider 37, that is, the fixed connection between the first slider 37 and the fixed sleeve 43 can be realized through the first connecting plate 48, and the rotating sleeve 42 is rotatably arranged inside the fixed sleeve 43; Each second bevel gear 41 is fixedly mounted on one end of a rotating sleeve 42, each first bevel gear 40 is located on one side of a first slider 37 and is fixedly connected to the shaft of a crushing roller 36, that is, when the first bevel gear 40 rotates, it can drive the crushing roller 36 to rotate, the first bevel gear 40 and the second bevel gear 41 are meshed with each other, a plurality of limit grooves 45 are provided on the surface of the rotating rod 44, each limit block 46 is slidably arranged inside a limit groove 45, and a plurality of limit blocks 46 are respectively fixedly mounted on the inner walls of the two rotating sleeves 42; When the two crushing rollers 36 need to be rotated, the second motor 49 is controlled to work, and the second motor 49 can drive the rotating rod 44 to rotate. Under the limiting action of the limiting block 46 and the limiting groove 45, the rotating rod 44 can drive the rotating sleeve 42 to rotate inside the fixed sleeve 43 when rotating, thereby driving the second bevel gear 41 to rotate. Since the second bevel gear 41 and the first bevel gear 40 are meshed with each other, when the second bevel gear 41 rotates, it can drive the first bevel gear 40 to rotate, thereby driving the crushing rollers 36 to rotate, so that the two crushing rollers 36 can rotate, and the rotation directions of the two crushing rollers 36 are opposite, which can achieve the crushing of grains; At the same time, when the first sliders 37 on both sides move to drive the two crushing rollers 36 to move, the first sliders 37 can drive the fixed sleeve 43 to move through the first connecting plate 48, thereby driving the rotating sleeve 42 to move, so that the limit block 46 can move inside the limit groove 45 without affecting the rotation of the rotating sleeve 42, that is, there is no need to stop the machine to adjust the position of the crushing roller 36.

[0039] like Figure 1-Figure 10As shown, the first transmission assembly includes a first driving wheel 22, a first driven wheel 23, a first transmission belt 24, a turntable 25, a hinged rod 26 and a lifting plate 27. The first driving wheel 22 is fixedly mounted on one end of one of the rotating shafts 16 away from the first sprocket 18. The first driven wheel 23 is rotatably arranged on the surface of the crushing box 11. The first transmission belt 24 is sleeved on the first driving wheel 22 and the first driven wheel 23. The turntable 25 is located at one side of the first driven wheel 23 and is coaxially fixedly connected to the first driven wheel 23. The lifting plate 27 is slidably arranged on one side of the crushing box 11. One end of the hinged rod 26 is hinged to the top end of the lifting plate 27, and the other end of the hinged rod 26 is hinged to the surface edge of the turntable 25. When the rotating shaft 16 rotates, it can drive the first driving wheel 22 to rotate. Under the action of the first transmission belt 24, it can drive the first driven wheel 23 to rotate. Since the first driven wheel 23 and the turntable 25 are coaxial and fixedly connected, the rotation of the first driven wheel 23 can drive the turntable 25 to rotate. Under the action of the hinged rod 26, when the turntable 25 rotates, it can drive the lifting plate 27 to move in the vertical direction.

[0040] like Figure 1-Figure 10 As shown, the telescopic assembly includes two first wedge blocks 29, two second wedge blocks 30, two connecting rods 31, four first fixing plates 32, four second fixing plates 33, four guide rods 34 and four springs 35. The two first wedge blocks 29 are symmetrically fixedly installed at the bottom end of the lifting plate 27, and each second wedge block 30 is located on one side of the first wedge block 29 and fits with the first wedge block 29. Specifically, the inclined surface of the first wedge block 29 fits with the inclined surface of the second wedge block 30. Each connecting rod 31 is fixed to the bottom end of a second wedge block 30, and the other end of each connecting rod 31 is fixedly connected to a first slider 37. Each first fixing plate 32 is fixedly mounted on the surface of a first sliding block 37, each second fixing plate 33 is located on one side of a first fixing plate 32 and fixed on the crushing box 11, each guide rod 34 is slidably disposed on a second fixing plate 33, and one end of each guide rod 34 is fixedly connected to the first fixing plate 32, each spring 35 is sleeved on a guide rod 34, and both ends of each spring 35 are respectively connected to the second fixing plate 33 and the first fixing plate 32; In the initial state, if Figure 2As shown, the spring 35 is in a compressed but not completely compressed state. When the lifting plate 27 moves downward, the lifting plate 27 can drive the first wedge block 29 to move. Since the inclined surfaces of the first wedge block 29 and the second wedge block 30 fit together, when the first wedge block 29 moves downward, it can drive the second wedge block 30 to move away from the first wedge block 29, so that the first slider 37 can be driven to move inside the first slide groove 38 through the connecting rod 31, so that the distance between the crushing rollers 36 can be adjusted. At this time, the spring 35 continues to be compressed. If the first wedge block 29 moves upward along with the lifting plate 27 , the first sliding block 37 can be driven to reset under the action of the spring 35 , thereby reducing the distance between the two crushing rollers 36 .

[0041] like Figure 1-Figure 10 As shown, each second transmission assembly includes a second connecting plate 50, a second driving wheel 61, a second driven wheel 62, a second transmission belt 63, an L-shaped plate 64 and two limiting rollers 65. The second connecting plate 50 is fixedly mounted on the top of a first slider 37, and the other end of the second connecting plate 50 is fixedly connected to a second slider 52 located above the first slider 37. The L-shaped plate 64 is fixedly mounted on one side of the second connecting plate 50. The second driven wheel 62 is rotatably arranged on the L-shaped plate 64. The second driving wheel 61 is located between the first bevel gear 40 and the first slider 37 and is fixed on the shaft of the crushing roller 36. The two limiting rollers 65 are rotatably arranged on the second connecting plate 50. The second transmission belt 63 is sleeved on the second driven wheel 62 and the second driving wheel 61, and the outer walls of the two limiting rollers 65 are both in contact with the second transmission belt 63. When the first bevel gear 40 rotates, it can drive the second driving wheel 61 to rotate. Under the action of the second transmission belt 63, when the second driving wheel 61 rotates, it can drive the second driven wheel 62 to rotate. The limiting roller 65 can guide and avoid the second transmission belt 63; By providing the second connecting plate 50, a fixed connection can be achieved between the first slider 37 and the second slider 52. Therefore, when the first slider 37 moves, it can drive the second slider 52 to move synchronously without affecting the normal operation of the second transmission assembly. At the same time, the rubber head 55 can also move with the movement of the crushing roller 36, so that the rubber head 55 can always knock on the crushing roller 36.

[0042] like Figure 1-Figure 10As shown, each swing assembly includes a swing rod 57, a strip groove 58, an insertion rod 59 and a rotating rod 60. One end of the driving rod 56 extends out of the second slider 52 and is fixedly connected to one end of the swing rod 57. The strip groove 58 is provided on the surface of the swing rod 57. The rotating rod 60 is located on a side of the L-shaped plate 64 away from the second driven wheel 62 and one end is coaxially fixedly connected to the second driven wheel 62. The insertion rod 59 is fixedly installed on one end of the rotating rod 60 away from the second driven wheel 62, and the insertion rod 59 is inserted into the inside of the strip groove 58. When the second driven wheel 62 rotates, it can drive the rotating rod 60 to rotate, and the rotating rod 60 can drive the insertion rod 59 to rotate. Since the insertion rod 59 is inserted into the strip groove 58, when the rotating rod 60 rotates, it can drive the swing rod 57 and the driving rod 56 to swing, thereby driving the knocking rod 54 and the rubber head 55 on the driving rod 56 to swing, so that the rubber head 55 can continuously knock on the crushing roller 36, knocking off the grains accumulated on the crushing roller 36, thereby cleaning the grains adhered to the crushing roller 36, which is beneficial to improving the crushing accuracy and crushing effect.

[0043] like Figure 1-Figure 10 As shown, three first accordion protective covers 39 are provided inside each first slide groove 38, and the two ends of the first accordion protective covers 39 located on both sides are respectively connected to the first slider 37 and the inner wall of the first slide groove 38, and the two ends of the first accordion protective cover 39 located in the middle position are respectively connected to the two first sliders 37. By setting the first accordion protective cover 39, the gap between the first slider 37 and the first slide groove 38 can be blocked to improve the sealing effect, and at the same time, the sliding of the first slider 37 will not be blocked.

[0044] like Figure 1-Figure 10 As shown, two second accordion protective covers 53 are provided inside each second slide groove 51, and both ends of each second accordion protective cover 53 are respectively connected to the second slider 52 and the inner wall of the second slide groove 51. The second accordion protective cover 53 can block the gap between the second slider 52 and the second slide groove 51 to improve the sealing effect, and at the same time will not hinder the sliding of the second slider 52.

[0045] like Figure 1-Figure 10 As shown, two first guide rails 28 are symmetrically fixed on the surface of the crushing box 11 and located on both sides of the lifting plate 27. The lifting plate 27 is slidably set on the two first guide rails 28. The lifting plate 27 can be guided by setting the first guide rails 28. A second guide rail 67 is provided below the two first guide rails 28. The second guide rail 67 is fixed on the surface of the crushing box 11. Each second wedge block 30 is slidably set on the second guide rail 67. The second wedge block 30 can be guided by the second guide rail 67, which is beneficial to improve the stability of the lifting plate 27 and the second wedge block 30 when moving.

[0046] The specific working process of the present invention is as follows: First, the opening between the two guide plates 15 is adjusted according to the size of the grains to be crushed, and the first motor 17 is controlled to work. The first motor 17 can drive the rotating shaft 16 to rotate. At this time, the rotating shaft 16 can drive the first sprocket 18 to rotate. Under the action of the chain 21, the first sprocket 18 can drive the second sprocket 19 to rotate synchronously when it rotates. At the same time, the second sprocket 19 and the gear 20 are coaxial and fixedly connected. Therefore, when the second sprocket 19 rotates, it can drive the gear 20 to rotate. Since the two gears 20 are meshed with each other, when one gear 20 rotates, it can drive the other gear 20 to rotate in the opposite direction. Therefore, the two guide plates 15 on both sides can be rotated, so that the opening between the two guide plates 15 can be increased or decreased. When the rotating shaft 16 rotates, it can drive the first driving wheel 22 to rotate. Under the action of the first transmission belt 24, it can drive the first driven wheel 23 to rotate. Since the first driven wheel 23 and the rotating disk 25 are coaxial and fixedly connected, the first driven wheel 23 can drive the rotating disk 25 to rotate when it rotates. Under the action of the hinge rod 26, when the rotating disk 25 rotates, it can drive the lifting plate 27 to move in the vertical direction. When the lifting plate 27 moves downward, the lifting plate 27 can drive the first wedge block 29 to move. Since the inclined surfaces of the first wedge block 29 and the second wedge block 30 are attached to each other, the lifting plate 27 can move in the vertical direction. Therefore, when the first wedge block 29 moves downward, it can drive the second wedge block 30 to the side away from the first wedge block 29, so that the first slider 37 can be driven to move inside the first slide groove 38 through the connecting rod 31, so that the distance between the crushing rollers 36 can be adjusted. At this time, the spring 35 continues to be compressed, and the distance between the two crushing rollers 36 becomes larger. If the first wedge block 29 moves upward with the lifting plate 27, the first slider 37 can be driven to reset under the action of the spring 35, so that the distance between the two crushing rollers 36 can be reduced. When the opening between the two guide plates 15 increases, the spacing between the two crushing rollers 36 increases synchronously to meet the crushing of larger grains. At the same time, the large opening between the two guide plates 15 is more conducive to the feeding of large grains, avoiding the influence of the small opening on the efficiency and speed, thereby improving the crushing efficiency of large grains. When the opening between the two guide plates 15 becomes smaller, the spacing between the two crushing rollers 36 becomes smaller synchronously, thereby being able to adapt to the crushing of grains with smaller particles, achieving effective crushing of small grains, and avoiding the situation where grains directly fall between the two crushing rollers 36. For the same kind of grain, by adjusting the distance between the two crushing rollers 36, the crushing force of the crushing rollers 36 on the grain can be adjusted, thereby being able to crush the same kind of grain into particles of different sizes, thereby meeting the crushing requirements of different particle sizes of the same kind of grain. At the same time, the second motor 49 is controlled to work, and the second motor 49 can drive the rotating rod 44 to rotate. Under the limiting action of the limiting block 46 and the limiting groove 45, the rotating rod 44 can drive the rotating sleeve 42 to rotate inside the fixed sleeve 43 when rotating, thereby driving the second bevel gear 41 to rotate. Since the second bevel gear 41 and the first bevel gear 40 are meshed with each other, when the second bevel gear 41 rotates, it can drive the first bevel gear 40 to rotate, thereby driving the crushing roller 36 to rotate, so that the two crushing rollers 36 can rotate, and the rotation directions of the two crushing rollers 36 are opposite, which can realize the crushing of grains; Then, the grains to be crushed are placed inside the feed port 12, and the grains are guided by the two guide plates 15 and fall between the two crushing rollers 36. The crushing of the grains is achieved by the rotating crushing rollers 36, and the crushed grains flow out through the discharge port 13; At the same time, when the first bevel gear 40 rotates, it can drive the second driving wheel 61 to rotate. Under the action of the second transmission belt 63, when the second driving wheel 61 rotates, it can drive the second driven wheel 62 to rotate. When the second driven wheel 62 rotates, it can drive the rotating rod 60 to rotate. The rotating rod 60 can drive the insertion rod 59 to rotate. Since the insertion rod 59 is inserted into the inside of the strip groove 58, when the rotating rod 60 rotates, it can drive the swing rod 57 and the driving rod 56 to swing, thereby driving the knocking rod 54 and the rubber head 55 on the driving rod 56 to swing, so that the rubber head 55 can continuously knock on the crushing roller 36, knock off the grains accumulated on the crushing roller 36, and realize the cleaning of the grains adhered to the crushing roller 36, which is beneficial to improve the crushing accuracy and crushing effect.
