Description

Technical Field

[0001] The invention relates to the technical field of bean grinding devices, and in particular to a composite double-layer bean grinding device for processing bean products. Background Art

[0002] In the process of soy product processing, the bean raw materials (such as soybeans, black beans, red beans, etc.) often need to be physically treated for screening and cleaning, and then the screened and cleaned bean raw materials are crushed and ground to form fine particles or powder for subsequent further processing and other operations.

[0003] According to patent announcement number CN106820978B, announcement date: 2019-03-01, a bean grinder is disclosed, including a hollow shell, a bottom shell connected to the hollow shell by a threaded structure, and a hollow structure arranged inside the hollow shell and the bottom shell, a support rod is fixed inside the hollow shell, a wire placement through-hole structure is arranged inside the support rod, a first motor is fixed on the top of the support rod, a conical plate is fixed on the top of the first motor spindle of the first motor, a plurality of cutting blades are fixed on the upper surface of the conical plate, a controller and a second motor are fixed on the side of the hollow shell, and a first Grinding wheel, the center of the interior of the first grinding wheel is sleeved with the second motor spindle in the second motor, the edge of the hollow shell located at the first grinding wheel is a curved structure, and the curvature is the same as the curvature of the first grinding wheel, the hollow shell is provided with two parallel second grinding wheels and third grinding wheels below the first grinding wheel, and both ends of the second grinding wheel and the third grinding wheel are connected to the interior of the hollow shell through a rotating shaft, a filter net is fixed inside the bottom shell, a liquid collecting structure is provided at the bottom of the bottom shell, a through hole structure connected to the liquid collecting structure is provided at the center of the bottom of the bottom shell, and a supporting leg is fixed to the bottom of the bottom shell.

[0004] In the prior art including the above-mentioned patent, when grinding bean raw materials, the bean raw materials are often directly placed between the grinding wheels, and the bean raw materials are crushed and ground by the rotation between the grinding wheels. This common grinding wheel has the characteristics of simple structure, easy production and operation. However, this method of grinding only by the rotation between the grinding wheels requires that the bean products be first crushed to form small particles, and then crushed to form finer particles during the grinding process. Therefore, in the early stage of grinding, the grinding wheel needs to spend more time on crushing the bean raw materials, which leads to an increase in the grinding time. If a crushing knife group is applied in the grinding container, the time for the grinding wheel to crush the bean raw materials can be reduced when the bean raw materials are ground, so that the grinding wheel spends more time on fine grinding, thereby improving the fineness of grinding and the grinding time. However, in the large-scale grinding process, the use of a crushing knife group requires regular grinding of the knife head of the crushing knife group or direct replacement of a new crushing knife group. Common crushing tools are often spiral blades fixedly mounted on the main shaft. To replace them, the entire machine must be disassembled and the knife group must be removed along the main shaft. This process is not only cumbersome, but if one of the multiple cutter heads on the spiral blade is seriously damaged, the entire spiral blade needs to be replaced, which increases production costs.

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-12 As shown, a composite double-layer bean grinding device for bean product processing comprises a grinding container 1 and composite double-layer grinding components arranged adjacent to each other in the vertical direction. The top opening of the grinding container 1 is covered with a cover 7 for closing the grinding container 1. The composite double-layer grinding component comprises a lower grinding table 8 which is rotatably arranged and an upper crushing knife group arranged on the top of the lower grinding table 8. The upper crushing knife group comprises:

[0037] The blade frame 3 is rotatably mounted on the cover 7 and moves synchronously with the cover 7;

[0038] The knife boxes 52 are arranged in a circular array and are respectively hingedly disposed on the sides of the knife plate holder 3;

[0039] The blade 5 is inserted into the blade box 52, and a locking groove 51 is opened on the blade 5. When the cover 7 closes the grinding container 1, the blade frame 3 is close to the top of the lower grinding table 8, and the blade box 52 and the retaining ring 83 provided on the top of the lower grinding table 8 cooperate to make the blade box 52 flip over. The blade box 52 flips over so that the locking rod 33 provided on the blade frame 3 is inserted and locked in the locking groove 51.

[0040] Specifically, a lower hopper 71 is fixedly mounted on the top of the cover 7, and the lower hopper 71 is connected to the cover 7. When the cover 7 is covered on the grinding container 1, the bean raw material can be put into the grinding container 1 along the lower hopper 71. The side of the knife plate frame 3 is provided with hinge grooves 32 arranged in a circular array, and the knife boxes 52 are hingedly arranged in the hinge grooves 32 respectively.

[0041] The blade holder 3 also includes a right-angle rod 34 slidably arranged in the blade holder 3, and a push spring 35 is fixedly installed on the right-angle rod 34. The first end of the push spring 35 is fixedly installed on the blade holder 3. The outer wall of the blade box 52 on one side of the locking rod 33 is provided with a through groove 53 matching the locking groove 51. In the default state, the push spring 35 pulls the right-angle rod 34 downward to make the right-angle rod 34 push the first end of the blade box 52 downward. At this time, the second end of the blade box 52 moves upward. The locking groove 51 is provided on the outer wall of the blade 5 near the first end. By inserting the first end of the blade 5 into The second end of the knife box 52 aligns and connects the locking groove 51 and the through groove 53 on the blade 5, and then drives the cover 7 to move down to close the top opening of the grinding container 1. At this time, the knife plate frame 3 and the cover 7 move down synchronously to approach the lower grinding table 8, and then under the cover of the retaining ring 83 fixedly installed on the lower grinding table 8, the first ends of the multiple knife boxes 52 are pushed respectively, so that the first end of the knife box 52 moves up and approaches the locking rod 33, and at the same time, the first end of the knife box 52 pushes the right-angle rod 34 to move the right-angle rod 34 up, and at this time, the push spring 35 deforms and accumulates force. Then the locking rod 33 passes through the through slot 53 and is inserted and locked in the locking slot 51, so that the blade 5 is locked in the blade box 52, and then when the blade frame 3 rotates, the multiple blades 5 on the blade frame 3 are used to preliminarily crush the bean raw materials entering the grinding container 1, and then the crushed bean raw materials are further ground and crushed when passing through the lower grinding table 8 and the inner wall of the grinding container 1, so as to achieve the effect of double-layer bean grinding through the blade 5 and the lower grinding table 8.

[0042] Furthermore, when it is necessary to replace or maintain a single blade 5, the top opening of the grinding container 1 is opened by driving the cover 7 upward, and then the blade frame 3 and the cover 7 are synchronously moved upward to move away from the lower grinding table 8. At this time, the push spring 35 releases the stored force to pull the right-angle rod 34 downward and make the right-angle rod 34 push the first end of the knife box 52 downward. When the first end of the knife box 52 moves downward, the locking rod 33 disengages from the through groove 53 and the locking groove 51 respectively, thereby releasing the lock on the blade 5, and the top opening of the grinding container 1 is opened due to the upward movement of the cover 7, which is convenient for quickly replacing or maintaining a single blade 5. At the same time, when the first end of the knife box 52 moves downward, the second end of the knife box 52 moves upward, so that the blade 5 can move up with the knife box 52 to maintain an upturned state, thereby avoiding the problem of the blade 5 slipping out of the knife box 52 due to the slight shaking caused by touching the cover 7 when replacing the blade 5, which affects the replacement of the blade 5.

[0043] Furthermore, by moving the cover 7 upward, not only can the grinding container 1 be opened, but also the blade 5 can be exposed and quickly unlocked for replacement. At the same time, the blade 5 is plugged into the blade box 52 as an independent individual, so that when a single blade 5 is damaged, it does not need to be replaced as a whole, thereby saving the cost of using the tool. By moving the cover 7 downward and quickly locking the blade 5, it is more convenient to disassemble and assemble compared with the traditional crushing knife set.

[0044] Furthermore, the method for the blade frame 3 to rotate and move synchronously with the cover 7 can be that a main shaft is rotatably set on the cover 7, the blade frame 3 is fixedly installed at the bottom end of the main shaft, and the output end of the motor fixedly installed on the cover 7 is fixedly installed at the top end of the main shaft, so that the motor is used to drive the blade frame 3 to rotate, and the blade frame 3 moves synchronously when the cover 7 is moved; it can also be that the output end of the motor fixedly installed on the cover 7 is directly fixedly installed on the blade frame 3, so that the cover 7 is moved to drive the blade frame 3 on the motor to move synchronously, and the motor is used to directly drive the blade frame 3 to rotate; or it can be any method known to those skilled in the art to drive the blade frame 3 to rotate and move synchronously with the cover 7.

[0045] Furthermore, the lower grinding table 8 can be rotated in the grinding container 1 by a motor arranged in the grinding container 1 and fixedly installed on the lower grinding table 8 to drive the lower grinding table 8 to rotate; or the main shaft rotatably arranged on the cover 7 is fixedly installed on the blade frame 3 and penetrates the blade frame 3, and the bottom end of the main shaft is inserted and limited to the top of the lower grinding table 8, and then when the motor on the cover 7 drives the main shaft to rotate, the main shaft drives the blade frame 3 and the lower grinding table 8 to rotate at the same time; or any method known to those skilled in the art to drive the lower grinding table 8 to rotate is possible.

[0046] In the above technical solution, double-layer grinding is achieved by the lower grinding table 8 and the upper crushing knife group in the composite double-layer grinding assembly. Secondly, by inserting multiple blades 5 into the knife box 52 respectively, and then when the cover 7 is covered on the top opening of the grinding container 1, the knife box 52 is flipped by the retaining ring 83 to insert and lock the locking rod 33 on the knife plate frame 3 into the locking groove 51, so as to quickly lock the blade 5. Therefore, when the cover 7 is moved up and the locking rod 33 is unlocked from the locking groove 51, it is convenient to quickly replace a single blade 5. Compared with the traditional crushing tool, the blade 5 is quickly locked and unlocked as an independent individual, which can cooperate with the grinding of the lower grinding table 8 to achieve the effects of crushing, grinding, and quickly replacing independent blade heads of the bean raw materials.

[0047] As an embodiment further provided by the present invention, it also includes a piston sleeve 77 which moves synchronously with the blade holder 3 and slides in a piston cavity 81 opened at the top of the lower grinding table 8. A sealing gasket 79 is fixedly installed at the bottom of the piston sleeve 77 to compress the piston cavity 81 when the blade holder 3 moves downward. When the cover 7 is detached from the grinding container 1, the sealing gasket 79 is reset to make the blade holder 3 away from the top of the lower grinding table 8.

[0048] Specifically, the piston sleeve 77 is fixedly mounted on the blade frame 3, and the piston sleeve 77 is rotated and arranged in the piston cavity 81, and then the corresponding motor is fixedly mounted on the cover 7, and the blade frame 3 is fixedly mounted on the output end of the motor, and then the cover 7 is moved down to close the top opening of the grinding container 1, at this time, the blade frame 3 and the motor on the cover 7 are synchronously moved down to approach the lower grinding table 8, and at the same time, the piston sleeve 77 on the blade frame 3 slides down in the piston cavity 81, so that the sealing gasket 79 is used to compress the piston cavity 81. Then, under the cover of the retaining ring 83 fixedly mounted on the lower grinding table 8, the first ends of the plurality of knife boxes 52 are pushed respectively, so that the first ends of the knife boxes 52 move up and approach the locking rod 33, and at the same time, the first end of the knife box 52 pushes the right-angle rod 34 to move the right-angle rod 34 upward, and at this time, the push spring 35 is deformed and stored. Then the locking rod 33 passes through the through slot 53 and is inserted and locked in the locking slot 51, so that the blade 5 is locked in the blade box 52. At this time, the cover 7 can be fixed to the grinding container 1 by bolts, buckles, etc.

[0049] Furthermore, when a single blade 5 needs to be replaced or maintained, the bolts or buckles fixing the cover 7 are removed. At this time, the sealing gasket 79 of the compressed piston chamber 81 is subjected to the rebound force of the compressed gas in the piston chamber 81, thereby quickly pushing the piston sleeve 77 and driving the blade holder 3 and the cover 7 to move upward, thereby opening the top opening of the grinding container 1, and then the blade holder 3 moves upward away from the lower grinding table 8. At this time, the push spring 35 releases the stored force to pull the right-angle rod 34 downward and cause the right-angle rod 34 to push the first end of the knife box 52 downward When the first end of the knife box 52 moves downward, the locking rod 33 disengages from the through groove 53 and the locking groove 51 respectively, thereby releasing the lock of the blade 5. Since the piston sleeve 77 moves upward to push the knife plate frame 3, the knife plate frame 3 located in the grinding container 1 can be pushed higher than the top opening of the grinding container 1. At this time, the blade 5 in the knife box 52 can be removed through the gap between the cover 7 and the grinding container 1, so that the blade 5 can be quickly replaced without completely separating the cover 7 from the grinding container 1.

[0050] As another embodiment provided by the present invention, it also includes a locking ring 2 rotatably arranged on the outer wall of the cover 7, and a plurality of foot rods 22 are arranged at the bottom of the locking ring 2, and a plurality of plug blocks 15 matching the foot rods 22 are arranged at the top of the grinding container 1. When the cover 7 is covered on the top opening of the grinding container 1, the locking ring 2 is rotated to allow the plug blocks 15 to be inserted and locked on the foot rods 22.

[0051] Specifically, a force ring 76 is fixedly installed on the outer wall of the cover 7, and the locking ring 2 is rotatably arranged on the force ring 76. A pressure handle 21 is symmetrically fixedly installed on the locking ring 2. A chamfered edge 11 is arranged on the top of the grinding container 1. A plurality of inserts 15 are arranged in a circular array and fixedly installed on the chamfered edge 11. The guide rods 75 symmetrically fixedly installed at the bottom of the cover 7 are respectively slidably arranged in the guide grooves 12 opened at the top of the chamfered edge 11, so that the guide rods 75 are used to make the cover 7 more stable when moving up and down. Figure 2As shown, the foot bar 22 is provided with a mounting groove 23. When it is needed, the user presses the pressing handle 21 separately and simultaneously, so that the pressing force acts on the cover 7 along the force ring 76, and then drives the cover 7 to move down to close the top opening of the grinding container 1. At this time, the blade frame 3 and the cover 7 move down synchronously to approach the lower grinding table 8. At the same time, the piston sleeve 77 fixedly installed on the blade frame 3 slides down in the piston cavity 81, so that the piston cavity 81 is compressed by the sealing gasket 79. Then, under the cover of the retaining ring 83 fixedly installed on the lower grinding table 8, the first ends of the plurality of knife boxes 52 are pushed respectively, so that the first ends of the knife boxes 52 move up and approach the locking rod 33. At the same time, the first end of the knife box 52 pushes the right-angle rod 34 to move the right-angle rod 34 upward, and the push spring 35 is deformed and stored. Then the locking rod 33 passes through the through slot 53 and is inserted and locked in the locking slot 51, so that the blade 5 is locked in the knife box 52. By continuing to press the locking ring 2 and making the bottom end of the cover 7 fit the chamfered edge 11 on the grinding container 1, and then rotating the locking ring 2 to drive the foot rod 22 to move and inserting the multiple plugs 15 into the mounting grooves 23 on the foot rod 22, the sealing gasket 79 compresses the piston chamber 81, so that the cover 7 is subjected to an upward reaction force, and the reaction force on the cover 7 is used to make the plug 15 stably located in the mounting groove 23, so that the cover 7 is quickly fixed on the grinding container 1. Similarly, by rotating the locking ring 2 again to make the plug 15 disengage from the mounting groove 23, the compressed gas in the piston chamber 81 expands and resets to push the piston sleeve 77, thereby driving the blade holder 3 and the cover 7 to move upward, and the cover 7 is away from the grinding container 1, so that the worker can quickly replace the blade 5 along the gap between the cover 7 and the grinding container 1.

[0052] Therefore, the sealing and unlocking of the grinding container 1 by the sealing cover 7 can be quickly achieved by utilizing the cooperation between the locking ring 2 and the insert block 15 .

[0053] As another embodiment provided by the present invention, it also includes a support sleeve 6 fixedly installed in the cover 7, and the blade holder 3 is rotatably set on the outer wall of the support sleeve 6, and the drive shaft 74 rotatably set in the support sleeve 6 and the blade holder 3 maintain transmission through the speed change gear assembly set in the support sleeve 6.

[0054] Specifically, a protective cover 61 is provided on the support sleeve 6, and the blade frame 3 is rotatably provided on the outer wall of the protective cover 61 on the support sleeve 6. The speed change gear assembly includes a fixed plate 62, a cylindrical gear 63, a small gear 64 and a large gear 66. Figure 5 As shown, the blade holder 3 is provided with an inner tooth opening 31, and the large gear 66 is rotatably arranged on the protective cover 61, and the tooth opening on the large gear 66 protrudes from the outer wall of the protective cover 61 and meshes with the inner tooth opening 31, as shown in FIG. Fig. 9As shown, a force-bearing shaft 65 is rotatably arranged inside the protective cover 61, and a small gear 64 and a large gear 66 are respectively fixedly mounted on the two ends of the force-bearing shaft 65, the small gear 64 and the inner teeth of the column gear 63 are meshed, the column gear 63 is fixedly mounted on the fixed plate 62, and the fixed plate 62 is fixedly mounted on the outer wall of the driving shaft 74.

[0055] Furthermore, a sealing cover 72 is fixedly installed on the top of the sealing cover 7, and a main motor 73 is fixedly installed in the sealing cover 72, and the top end of the driving shaft 74 is fixedly installed on the output end of the main motor 73. The driving shaft 74 is driven to rotate by the main motor 73, and then the driving shaft 74 rotates to mesh the cylindrical gear 63 and the pinion 64. Since the number of teeth of the cylindrical gear 63 and the pinion 64 is proportional, the force shaft 65 rotates multiple times when the driving shaft 74 rotates a single circle, and the large gear 66 is meshed with the inner tooth 31, thereby driving the blade frame 3 to rotate. The tooth ratio of the cylindrical gear 63 and the small gear 64 is greater than the tooth ratio of the inner tooth 31 and the large gear 66, and then when the driving shaft 74 rotates a single circle, the blade frame 3 is driven to rotate faster, thereby crushing the bean raw material.

[0056] As another embodiment provided by the present invention, the bottom end of the driving shaft 74 is fixedly mounted on the piston sleeve 77, and the side portions 78 symmetrically arranged on the piston sleeve 77 are slidably arranged in the limiting grooves 82 symmetrically opened at the mouth of the piston cavity 81, and the lower grinding table 8 and the driving shaft 74 rotate synchronously.

[0057] Specifically, Figure 4 and Fig. 9 As shown, the limiting groove 82 is provided at the cavity opening of the piston cavity 81, and the side edge portion 78 on the piston sleeve 77 slides in the limiting groove 82. Since the bottom end of the driving shaft 74 is fixedly mounted on the piston sleeve 77, when the main motor 73 drives the driving shaft 74 to rotate, the piston sleeve 77 on the driving shaft 74 is limited in the limiting groove 82 through the side edge portion 78, thereby driving the lower grinding table 8 to rotate. At the same time, due to the rotation of the driving shaft 74, the cylindrical gear 63 and the pinion gear 64 are meshed. Since the number of teeth of the cylindrical gear 63 and the pinion gear 64 are proportional, when the driving shaft 74 rotates a single circle, the force shaft 65 rotates multiple circles and makes the large gear 66 mesh with the inner tooth opening 31, thereby driving the blade holder 3 to rotate. The tooth ratio of the cylindrical gear 63 and the small gear 64 is greater than the tooth ratio of the inner tooth 31 and the large gear 66, so that when the driving shaft 74 rotates a single circle, the knife plate frame 3 is driven to rotate faster to crush the bean raw material.

[0058] Therefore, the lower grinding table 8 and the driving shaft 74 rotate at the same speed, while the blade holder 3 rotates faster through the transmission of the gears, and then while the lower grinding table 8 is used for stable grinding, the blade holder 3 can also rotate at a high speed, thereby driving the blade 5 to rotate at a high speed to achieve the effect of cutting. If the rotation speed of the lower grinding table 8 and the blade 5 is made the same, it will cause instability when the rotation speed is fast, and the cutting effect of the blade 5 will be poor when the rotation speed is slow. Therefore, the rotation speeds of the lower grinding table 8 and the blade 5 are inconsistent, so that the blade 5 can cut quickly, while the lower grinding table 8 rotates slowly and stably to achieve the effect of grinding.

[0059] As the best embodiment provided by the present invention, a sloped portion 87 is provided on the side of the lower grinding table 8 close to the bottom of the grinding container 1, and the lower grinding table 8 reciprocates in the vertical direction so that the distance between the sloped portion 87 and the bottom of the grinding container 1 is adjustable.

[0060] Specifically, the retaining ring 83 is slidably set on the top of the lower grinding table 8, and a plurality of extrusion springs 84 are fixedly installed on the bottom end of the retaining ring 83. The first end of the extrusion spring 84 is fixedly installed on the lower grinding table 8. The retaining ring 83 is pushed by the extrusion spring 84 so that when the knife plate holder 3 approaches the lower grinding table 8, the extrusion spring 84 overcomes the elastic force of the pushing spring 35, so that the retaining ring 83 pushes the first end of the knife box 52 to move up and approach the locking rod 33, and the pushing spring 35 is squeezed and stored.

[0061] Furthermore, a grinding plate 43 matching with the inclined surface 87 is fixedly installed at the bottom of the grinding container 1, and the grinding plate 43 is conical so that there is a grinding gap between the grinding plate 43 and the inclined surface 87. At the same time, the lower position of the grinding plate 43 is conical and connected to the discharge port 13 opened at the bottom of the grinding container 1. The grinding container 1 is closed by the cover 7. At this time, the driving shaft 74 on the cover 7 drives the piston sleeve 77 to slide down into the piston cavity 81, so that the piston cavity 81 is compressed by the sealing gasket 79. Then, when the main motor 73 drives the driving shaft 74 to rotate, the piston sleeve 77 on the driving shaft 74 is limited in the limiting groove 82 through the side portion 78, thereby driving the lower grinding table 8 to rotate. At the same time, due to the rotation of the driving shaft 74, the cylindrical gear 63 and the small gear 64 are meshed, and the large gear 66 and the inner tooth mouth 31 are meshed, thereby driving the blade frame 3 to rotate. Therefore, the blade 5 on the blade frame 3 is rotated to crush the bean raw material. The crushed bean raw materials slide along the side wall of the lower grinding table 8 and the inner wall of the grinding container 1 to the grinding gap between the grinding plate 43 and the inclined portion 87, and then the lower grinding table 8 rotates to grind the crushed bean raw materials between the side wall of the lower grinding table 8 and the inner wall of the grinding container 1 and the crushed bean raw materials between the grinding gap. At the same time, because the lower grinding table 8 reciprocates in the vertical direction, the grinding gap spacing between the grinding plate 43 and the inclined portion 87 is adjustable. When the inclined portion 87 moves away from the grinding plate 43 to increase the grinding gap spacing, the crushed bean raw materials are easier to enter the grinding gap. Then, when the inclined portion 87 approaches the grinding plate 43 to reduce the grinding gap spacing, the rotation and extrusion of the inclined portion 87 are used to grind the crushed beans more finely. Secondly, because the blade frame 3 rotates on the protective cover 61, its position relative to the cover 7 is fixed, so when the lower grinding table 8 moves up to get closer to the blade frame 3, the squeezing spring 84 is squeezed, and the retaining ring 83 still maintains the state of pushing the first end of the blade box 52. Therefore, the blade 5 can be stabilized in the blade box 52, and the lower grinding table 8 can achieve reciprocating movement in the vertical direction.

[0062] Therefore, the method of reciprocating the lower grinding table 8 in the vertical direction to adjust the grinding gap distance can improve the discharge of the crushed bean raw material while performing a more precise grinding operation.

[0063] Furthermore, the lower grinding table 8 can be reciprocated in the vertical direction by a motor cooperating with a cam to push and drive the lower grinding table 8 to reciprocate in the vertical direction; or the lower grinding table 8 can be reciprocated by an electric push rod; or any other method known to those skilled in the art to drive the lower grinding table 8 to reciprocate in the vertical direction.

[0064] As another embodiment provided by the present invention, a discharge port 13 connected to the inner side of the grinding container 1 is provided at the bottom, a corrugated ring 4 is fixedly installed on the inner wall of the discharge port 13, and a moving rod 88 fixedly installed on the lower grinding table 8 moves along a plurality of staggered high portions 41 and low portions 42 arranged on the top of the corrugated ring 4.

[0065] Specifically, Figure 6 , Figure 7 and Fig.11 As shown, the high portion 41 and the low portion 42 are continuously staggered and distributed to present a corrugated state, and the moving rod 88 fixedly installed on the lower grinding table 8 rotates with the lower grinding table 8 to move along the multiple high portions 41 and the low portions 42. When the moving rod 88 moves to the high portion 41, the moving rod 88 drives the lower grinding table 8 to move upward, and when the moving rod 88 moves to the low portion 42, the lower grinding table 8 moves downward under the action of gravity and the expansion of the compressed gas in the piston chamber 81. Therefore, when the moving rod 88 moves between the multiple high portions 41 and the low portions 42, the effect of reciprocating movement of the lower grinding table 8 in the vertical direction is achieved.

[0066] As another embodiment provided by the present invention, the inner wall of the grinding container 1 is provided with a plurality of offset plates 9 arranged in a circular array for sliding along the vertical direction, and the offset plates 9 and the lower grinding table 8 keep synchronously moving in opposite directions.

[0067] Specifically, the inner wall of the grinding container 1 is provided with sliding cavities 14 arranged in a circular array, and the offset plates 9 are slidably disposed in the sliding cavities 14. A grinding ring plate 85 is fixedly mounted on the side wall of the lower grinding table 8, and a plurality of offset plates 9 slide on the inner wall of the grinding container 1 and are respectively located on one side of the grinding ring plate 85. When the moving rod 88 moves between the high-position portion 41 and the low-position portion 42 on the corrugated ring 4 to reciprocate the lower grinding table 8 in the vertical direction, the offset plates 9 and the lower grinding table 8 maintain synchronous reverse movement, that is, when the lower grinding table 8 moves upward relative to the grinding container 1, the offset plates 9 move downward relative to the grinding container 1, and when the lower grinding table 8 moves downward relative to the grinding container 1, the offset plates 9 move upward relative to the grinding container 1. Therefore, the offset plates 9 and the lower grinding table 8 maintain synchronous reverse movement, so that when the offset plates 9 and the lower grinding table 8 move relative to each other, On this basis, by the offset plate 9 and the lower grinding table 8 moving in opposite directions at the same time, the relative movement distance between the offset plate 9 and the lower grinding table 8 is greatly increased when the offset plate 9 and the lower grinding table 8 move in opposite directions at the same time, compared with the lower grinding table 8 being stationary while the offset plate 9 moves or the offset plate 9 being stationary while the lower grinding table 8 moves. Therefore, the bean raw material located between the offset plate 9 and the lower grinding table 8 and crushed by the blade 5 can be better ground under the relative movement between the offset plate 9 and the lower grinding table 8, thereby improving the grinding effect of the crushed bean raw material.

[0068] Furthermore, the method for driving the offset plate 9 and the lower grinding table 8 to maintain synchronous reverse movement can be to use a motor in conjunction with a cam to keep the offset plate 9 and the lower grinding table 8 moving in opposite directions; or to use an electric push rod to push and pull the offset plate 9 to keep the offset plate 9 and the lower grinding table 8 moving in opposite directions; or any method known to those skilled in the art to drive the lower grinding table 8 to move back and forth in the vertical direction.

[0069] As another embodiment further provided by the present invention, it also includes a hinged rod 93 hingedly arranged on the grinding container 1 and corresponding to the offset plate 9, a lever 95 arranged on the offset plate 9 slides in a waist groove 94 opened near the first end of the hinged rod 93, and the second end of the hinged rod 93 is located on the moving path of the extrusion ring 86 arranged on the side wall of the lower grinding table 8, and a main spring 92 arranged on the offset plate 9 is deformed and stores force when the offset plate 9 moves upward.

[0070] Specifically, the hinged rod 93 is hingedly arranged in the sliding cavity 14 opened on the inner wall of the grinding container 1, the extrusion ring 86 is fixedly installed on the side wall of the lower grinding table 8 and is located below the grinding ring plate 85, and the two ends of the main spring 92 are respectively fixedly installed on the bottom end of the offset plate 9 and the grinding container 1.

[0071] Further, such as Fig.10 As shown, the second end of the hinged rod 93 is located below the extrusion ring 86, and the moving rod 88 fixedly installed on the lower grinding table 8 rotates with the lower grinding table 8 to move along the plurality of high-position parts 41 and the low-position parts 42. When the moving rod 88 moves to the high-position part 41, the moving rod 88 drives the lower grinding table 8 to move upward, and the main spring 92 pulls the offset plate 9 to move downward. Then, when the moving rod 88 moves to the low-position part 42, the lower grinding table 8 moves downward under the action of gravity and the expansion of the compressed gas in the piston chamber 81. The extrusion ring 86 on the grinding table 8 begins to press down on the second end of the hinge rod 93. At this time, the first end of the hinge rod 93 moves up to allow the lever 95 to slide in the waist groove 94, and the offset plate 9 moves up to pull the main spring 92 to deform and store force. Therefore, under the action of the hinge rod 93 and the main spring 92, when the lower grinding table 8 moves up, the offset plate 9 moves down synchronously, and when the lower grinding table 8 moves down, the offset plate 9 moves up synchronously, so that the offset plate 9 and the lower grinding table 8 always keep synchronous reverse movement, thereby improving the grinding effect of the crushed bean raw materials between the offset plate 9 and the lower grinding table 8.

[0072] As a further optimal embodiment of the present invention, a grinding plate 43 is provided on one side of the inclined surface 87 at the bottom of the grinding container 1 , and a knocking rod 91 fixedly mounted on the offset plate 9 moves upward with the offset plate 9 to knock the grinding plate 43 .

[0073] Specifically, a plurality of grinding convex points 44 for enhancing the grinding effect are arranged on the inner wall of the grinding plate 43. And the knocking rod 91 fixedly mounted on the dislocation plate 9 knocks the grinding plate 43 when the dislocation plate 9 moves to the highest position.

[0074] Furthermore, when the grinding container 1 needs to be installed and used, the first end of the blade 5 is inserted into the second end of the blade box 52 so that the locking groove 51 and the through groove 53 on the blade 5 are aligned and connected, and then the user presses the pressing handle 21 separately and simultaneously, so that the pressing force acts on the cover 7 along the force ring 76, and then drives the cover 7 to move down to close the top opening of the grinding container 1. At this time, the blade frame 3 moves down synchronously with the cover 7 through the support sleeve 6 and the protective cover 61 and approaches the lower grinding table 8. At the same time, the piston sleeve 77 fixedly installed on the blade frame 3 slides down into the piston cavity 81 so that the sealing gasket 79 is used to compress the piston cavity 81. Then, under the cover of the retaining ring 83 fixedly installed on the lower grinding table 8, the first ends of the plurality of blade boxes 52 are pushed respectively, so that the first ends of the blade boxes 52 move up and approach the locking rod 33, and at the same time, the first end of the blade box 52 pushes the right-angle rod 34 to move the right-angle rod 34 upward, and at this time, the push spring 35 deforms and accumulates force. Then the locking rod 33 passes through the through slot 53 and is inserted and locked in the locking slot 51 , so that the blade 5 is locked in the blade box 52 .

[0075] Furthermore, by continuing to press the locking ring 2 and making the bottom end of the cover 7 fit against the chamfered edge 11 on the grinding container 1, and then rotating the locking ring 2 to drive the foot rod 22 to move and inserting a plurality of plug blocks 15 into the mounting grooves 23 on the foot rod 22, the sealing gasket 79 compresses the piston chamber 81, so that the cover 7 is subjected to an upward reaction force, and the reaction force exerted on the cover 7 is utilized to make the plug blocks 15 stably located in the mounting grooves 23, so that the cover 7 is quickly fixed on the grinding container 1.

[0076] Then, the bean raw material is put into the grinding container 1 through the lower hopper 71, and the main motor 73 is started. Then, the main motor 73 drives the driving shaft 74 to rotate. At this time, the piston sleeve 77 on the driving shaft 74 is limited in the limiting groove 82 through the side portion 78, thereby driving the lower grinding table 8 to rotate. At the same time, due to the rotation of the driving shaft 74, the cylindrical gear 63 and the pinion gear 64 are meshed to rotate the pinion gear 64. The pinion gear 64 rotates the large gear 66 through the force shaft 65 and meshes with the inner tooth opening 31, thereby driving the blade frame 3 to rotate. Since the tooth opening ratio of the cylindrical gear 63 and the small gear 64 is greater than the tooth opening ratio of the inner tooth opening 31 and the large gear 66, when the driving shaft 74 rotates a single circle, the blade frame 3 is driven to rotate faster to crush the bean raw material.

[0077] When the lower grinding table 8 rotates, the lower grinding table 8 is used to grind the crushed bean raw materials between the side wall of the lower grinding table 8 and the inner wall of the grinding container 1 and the crushed bean raw materials in the grinding gap between the grinding plate 43 and the inclined surface 87 at the same time. As the lower grinding table 8 rotates, the moving rod 88 rotates with the lower grinding table 8 to move along the multiple high-position parts 41 and the low-position parts 42. When the moving rod 88 moves to the high-position part 41, the moving rod 88 drives the lower grinding table 8 to move upward, and the main spring 92 pulls the offset plate 9 to move downward. Then, when the moving rod 88 moves to the low-position part 42, the lower grinding table 8 is under the action of gravity. The lower grinding table 8 moves downward under the action of the expansion of the compressed gas in the piston chamber 81. At this time, the extrusion ring 86 on the lower grinding table 8 begins to press down on the second end of the hinge rod 93. At this time, the first end of the hinge rod 93 moves upward to allow the lever 95 to slide in the waist groove 94, and the offset plate 9 moves upward to pull the main spring 92 to deform and store force. When the offset plate 9 moves up to the highest position, the knocking rod 91 on the offset plate 9 knocks the grinding plate 43 to make the grinding plate 43 vibrate. At this time, the ground bean raw materials in the grinding gap between the grinding plate 43 and the inclined portion 87 move to the discharge port 13 faster due to the vibration of the grinding plate 43, and then are discharged from the grinding container 1 along the discharge port 13.

[0078] When the worn blade 5 needs to be replaced, the locking ring 2 is rotated to disengage the insert 15 from the mounting groove 23. At this time, the compressed gas in the piston chamber 81 expands and resets to push the piston sleeve 77, thereby driving the drive shaft 74 to move upward. At the same time, the drive shaft 74 drives the cover 7 to move upward and drives the blade holder 3 to move upward synchronously through the support sleeve 6 and the protective cover 61. At this time, the cover 7 and the blade holder 3 move upward at the same time relative to the top of the lower grinding table 8. When the blade holder 3 and the cover 7 move upward synchronously to move away from the lower grinding table 8, the push spring 35 releases the stored force to pull the right-angle rod 34 downward and make the right-angle rod 34 push the first end of the knife box 52 downward. When the first end of the knife box 52 moves downward, the locking rod 33 disengages from the through groove 53 and the locking groove 51 respectively, thereby releasing the lock on the blade 5, and the top opening of the grinding container 1 is opened due to the upward movement of the cover 7. At this time, the blade 5 can be quickly replaced from the gap between the bottom end of the cover 7 and the top end of the grinding container 1, so that the blade 5 can be quickly replaced without removing the cover 7.

[0079] The cover 7, the driving shaft 74 and the lower grinding table 8 are mutually embedded or limited, so that when the cover 7 is removed from the grinding container 1, the lower grinding table 8 can also be removed from the grinding container 1 along with the driving shaft 74, thereby facilitating the cleaning of the grinding container 1.

[0080] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
