DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0048] After the wheat particles are ground, the moisture content of the flour is kept stable to avoid moisture content fluctuations caused by environmental changes during production and storage, thereby ensuring the quality of the flour. At the same time, the humidity of the powder is increased, effectively reducing the accumulation of static electricity.

[0049] Reference Figure 1-4 A wheat crushing device includes a crushing box 1 with an upper opening, a mesh plate 18 and a discharge port 5.

[0050] A crushing assembly is arranged on the upper part of the crushing box 1 for grinding and crushing the hulled wheat particles; the crushing assembly comprises a motor frame 19 , a first motor 21 , two symmetrically arranged crushing rollers 3 and a gear 20 .

[0051] The first motor 21 is connected to the back side of the crushing box 1 through the motor frame 19 .

[0052] Two gears 20 are arranged on the back of the crushing box 1 in a meshing state, and the output shaft of the first motor 21 is connected to one of the gears 20 .

[0053] Two symmetrically arranged crushing rollers 3 are respectively connected to different gears 20 via rotating shafts, and the grains enter from the gap between the two crushing rollers 3 and are ground and crushed.

[0054] Two blanking plates 2 are symmetrically arranged in the crushing box 1 above the crushing roller 3 , and the position of the gap between the lower ends of the two blanking plates 2 matches the position of the gap between the two crushing rollers 3 .

[0055] The mesh plate 18 is located in the middle of the crushing box 1, and one end of the mesh plate 18 is movably connected to the inner wall of the crushing box 1 through a hinge.

[0056] Reference Figure 8-9 A confluence cavity 14 is formed at one end of the mesh plate 18 , and a plurality of groups of humidity control components 12 are arranged in an array along the long side direction of the confluence cavity 14 .

[0057] The humidity control assembly 12 includes a water overflow hole 121 , a guide rod 122 , a ball 123 , a first connecting cavity 124 , a bracket 125 and a second connecting cavity 126 .

[0058] The ball 123 is slidably disposed in the first communication cavity 124 , cooperates with the overflow hole 121 and regulates the overflow of water.

[0059] The overflow hole 121 is formed at one end of the mesh plate 18 , and the overflow hole 121 is connected to the inside of the second connecting cavity 126 through the first connecting cavity 124 .

[0060] The bracket 125 is installed in the first communicating cavity 124 , and the guide rod 122 is installed on the bracket 125 along the direction of the first communicating cavity 124 .

[0061] The ball 123 is sleeved on the guide rod 122 . When the ball 123 moves outside the guide rod 122 , a gap is provided between the ball 123 and the inner wall of the first connecting cavity 124 , and the ball 123 and the overflow hole 121 cooperate with each other.

[0062] The second connecting cavity 126 is connected to the confluence cavity 14 . A water injection hole 24 is provided on one side of the confluence cavity 14 , and the confluence cavity 14 is connected to an external water supply device through the water injection hole 24 .

[0063] To this end, after the wheat grains are uniformly injected into the crushing box 1, they contact the two feeding plates 2 at the upper ends, and fall between the two crushing rollers 3 along the feeding plates 2. The first motor 21 is started to drive the two crushing rollers 3 to rotate in opposite directions, and then the wheat grains are squeezed, ground and crushed by the extrusion force generated between the two crushing rollers 3. The ground wheat powder falls on the mesh plate 18. The mesh plate 18 is actually a filtering sieve plate. Part of the flour will pass through the mesh plate 18 and fall directly on the inclined plate 6. The initial state of the mesh plate 18 is a setting that is inclined downward toward the direction close to the turning class 10. At this time, the ball 123 is affected by its own gravity and moves along the guide rod 122 to a position close to the overflow hole 121. The ball 123 in the first connecting cavity 124 moves to the side away from the overflow hole 121, so that the water in the first connecting cavity 124, the second connecting cavity 126 and the confluence cavity 14 will pass through the overflow hole 121 to flow to the outside and drip onto the upper surface of the next connecting cavity 10.

[0064] Since the flipping plate 10 is mainly used to catch the flour sliding down from the mesh plate 18, when the upper end surface of the flipping plate 10 is wetted, it will come into contact with the flour, so that the flour can be effectively brought into contact with water. By controlling the pitch angle of the mesh plate 18, water is intermittently discharged according to the position of the flipping plate 10. Compared with the traditional humidity control structure, such a design can, firstly, control the water flow rate and the position of water droplets, and secondly, effectively prevent the problem of a large amount of flour adhering to the inner wall of the box due to the unstable water falling point.

[0065] Secondly, the wetted flour sliding down from the turning plate 10 falls on the inclined plate 6. At this time, the powder that originally directly passed through the mesh plate 18 and fell on the inclined plate 6 will come into contact with the wetted powder, thereby wetting all the powder. Example

[0066] The mesh plate 18 mentioned above is actually a sieve plate 18. The expected effect of the sieve plate is to screen the powder and let it pass through, while preventing the powder from falling and causing blockage. However, in the actual production process, when the powder falls on the mesh plate 18, the van der Waals force, electrostatic force and surface energy between the powders cause the powders to gather together and not fall. In real life, when a colander is used to hold flour, the flour will not fall. The principle is that there are multiple forces between the powders. If a vibrating screen is used, not only the noise will be increased, but the vibration will also affect the overall operation of the equipment. When too much flour gathers on the mesh plate 18, the internal temperature is too high, which will cause starch damage. At the same time, the accumulation is too high, affecting the normal operation of the crushing roller 3 above.

[0067] refer to Figure 5-6 The difference between this embodiment and embodiment 1 is that a mounting frame 4 is provided on one side of the crushing box 1, and a material cleaning component is provided in the mounting frame 4.

[0068] The material clearing assembly includes a lower channel 7 , an upper flow channel 15 , a vertical slot 23 , a second motor 22 , a transmission gear 16 , a chain 17 and a material turning plate 10 .

[0069] The upper flow channel 15 is arranged in an arc shape between the crushing box 1 and the inside of the mounting frame 4, the vertical groove 23 is opened in the middle of the crushing box 1, and the upper flow channel 15, the vertical groove 23 and the lower channel 7 are interconnected.

[0070] The two transmission teeth 16 and the chain 17 meshing on their outer sides are both located in the vertical groove 23 . The upper transmission teeth 16 are connected to the output shaft of the second motor 22 . A turning plate 10 is horizontally mounted on the chain plate of the chain 17 .

[0071] A baffle 11 is hingedly connected to one end of the mesh plate 18 close to the turning plate 10 .

[0072] When the turning plate 10 moves upward, it will contact the mesh plate 18 and the baffle plate 11 above respectively, and drive the baffle plate 11 and the mesh plate 18 to deflect respectively.

[0073] To this end, the second motor 22 is used to provide power to the transmission gear 16, which drives the chain 17 to rotate. At the same time, the flipping plate 10 is horizontally fixed on the outside of the chain 17. Driven by the chain 17, the position of the flipping plate 10 is continuously moved. During the upward movement of the flipping plate 10 close to the mesh plate 18, the powder sliding down from the inclined mesh plate 18 is caught. As the flipping plate 10 moves, the powder will pass through the upper flow channel 15 together, and slide out from the lower channel 7 at the lower end and fall onto the inclined plate 6. At the same time, the size of the flipping plate 10 matches the size of the inner side of the upper flow channel 15.

[0074] The advantages of this component design are:

[0075] It can effectively solve the problem of powder accumulation on the mesh plate 18. At the same time, intermittent material dropping can prevent the discharge port 5 from being blocked. Secondly, the flipping plate 10 can assist in adjusting the angle of the mesh plate 18. Finally, when the flipping plate 10 and the baffle 11 contact each other, the baffle 11 hinged on the mesh plate 18 will be flipped upward. The flipped baffle 11 has the effect of blocking the powder, which can avoid the problem of excessive powder falling from the flipping plate 10. Example

[0076] When the turning plate 10 completes receiving the materials, some powder will adhere to the surface, so it needs to be cleaned in time.

[0077] refer to Figure 7-9 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that a cleaning component for cleaning the turning plate 10 is also provided on the inner side of the lower channel 7 .

[0078] The cleaning assembly includes a first elastic rope 8 and a cleaning roller 9. The cleaning roller 9 is rotatably connected to the inner upper end of the lower channel 7 through the first elastic ropes 8 on both sides, and the position of the cleaning roller 9 cooperates with the position of the turning plate 10.

[0079] An inclined plate 6 inclined toward the discharge port 5 is provided at the bottom of the crushing box 1 , and the upper portion of the inclined plate 6 matches the height of the lower edge of the lower channel 7 .

[0080] To this end, when the flipping plate 10 rotates downward, the side that originally received the material faces downward. At this time, when the flipping plate 10 contacts the cleaning roller 9 that is rotated and arranged between the two first elastic ropes 8, the cleaning roller 9 will move along the surface of the flipping plate 10. In this way, through contact, the cleaning roller 9 with a rough surface will clean the powder adhered to the surface of the flipping plate 10. At the same time, the flipping plate 10 contacts the cleaning roller 9 during the return journey, changing the position of the cleaning roller 9. However, the first elastic ropes 8 connected on both sides of the flipping plate 10 are elastic, which will assist the cleaning roller 9 to return to its initial position and continue to clean the next flipping plate 10. Example

[0081] If the powder slides down the inclined screen plate 18 only by its own gravity, the amount of powder that slides down will be very small.

[0082] refer to Figure 5 The difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is that a shaking assembly 13 is installed at the bottom of the mesh plate 18 away from the flipping plate 10.

[0083] The shaking assembly 13 includes a second elastic rope 131 , a fixing head 132 and a third elastic rope 133 .

[0084] The third elastic rope 133 is connected between the mesh plate 18 and the inner wall of the crushing box 1, the fixing head 132 is installed on the third elastic rope 133, the second elastic rope 131 is connected between the fixing head 132 and the inner wall of the crushing box 1, and the second elastic rope 131 and the third elastic rope 133 are arranged in a cross shape.

[0085] To this end, an elastic member consisting of a second elastic rope 131, a fixed head 132 and a third elastic rope 133 is provided on the side of the mesh plate 18 away from the flipping plate 10. When the flipping plate 10 contacts the mesh plate 18, the third elastic rope 133 is in a stretched state to store elastic potential energy. After the flipping plate 10 is separated from the mesh plate 18 and the external force is removed, the third elastic rope 133 will try to return to its original shape, that is, a straight line state when not subjected to force. In this process, the third elastic rope 133 will exceed its equilibrium position because it has a tendency to return to its original state. This movement exceeding the equilibrium position will cause the third elastic rope 133 and the second elastic rope 131 to vibrate until all the elastic potential energy is dissipated through internal friction damping. The jitter generated by this process can help the mesh plate 18 to smoothly transfer the powder to the flipping plate 10.

[0086] The working principle of the device is:

[0087] After the wheat particles are ground, the moisture content of the flour is kept stable to avoid moisture content fluctuations caused by environmental changes during production and storage, thereby ensuring the quality of the flour. At the same time, the humidity of the powder is increased, effectively reducing the accumulation of static electricity.

[0088] To this end, after the wheat particles are uniformly injected into the crushing box 1, they contact the two feeding plates 2 at the upper end, and fall into between the two crushing rollers 3 along the feeding plates 2. The first motor 21 is started to drive the two crushing rollers 3 to rotate in opposite directions, and then the wheat particles are squeezed, ground and crushed by the extrusion force generated between the two crushing rollers 3. The ground wheat powder falls on the mesh plate 18. The mesh plate 18 is actually a filtering sieve plate. Part of the flour will pass through the mesh plate 18 and fall directly on the inclined plate 6. The initial state of the mesh plate 18 is a setting that is inclined downward toward the direction close to the turning class 10. At this time, the ball 123 is affected by its own gravity and moves along the guide rod 122 toward the overflow hole 1 21 moves to the position until the ball 123 blocks the overflow hole 121. At this time, the water will not flow outward. When the flipping plate 10, which has been in motion, moves upward, the uppermost flipping plate 10 will first contact with the mesh plate 18, giving the mesh plate 18 an upward thrust, driving the mesh plate 18 to deflect upward. In the process of the mesh plate 18 deflecting upward, the mesh plate 18 will tilt to the other side. At this time, the ball 123 in the first connecting cavity 124 will move to the side away from the overflow hole 121, so that the water in the first connecting cavity 124, the second connecting cavity 126 and the confluence cavity 14 will pass through the overflow hole 121 to flow to the outside and drip onto the upper surface of the flipping plate 10 below.

[0089] Since the flipping plate 10 is mainly used to catch the flour sliding down from the mesh plate 18, when the upper end surface of the flipping plate 10 is wetted, it will come into contact with the flour, so that the flour can be effectively brought into contact with water. By controlling the pitch angle of the mesh plate 18, water is intermittently discharged according to the position of the flipping plate 10. Compared with the traditional humidity control structure, such a design can, firstly, control the water flow rate and the position of water droplets, and secondly, effectively prevent the problem of a large amount of flour adhering to the inner wall of the box due to the unstable water falling point.

[0090] The mesh plate 18 mentioned above is actually a sieve plate. The expected effect of the sieve plate is to screen the powder and let it pass through, while preventing the powder from falling and causing blockage. However, in the actual production process, when the powder falls on the mesh plate 18, the van der Waals force, electrostatic force and surface energy between the powders cause the powders to gather together and not fall. In real life, when a colander is used to hold flour, the flour will not fall. The principle is that there are multiple forces between the powders. If a vibrating screen is used, not only the noise will be increased, but the vibration will also affect the overall operation of the equipment. When too much flour gathers on the mesh plate 18, the internal temperature is too high, which will cause starch damage. At the same time, the accumulation is too high, affecting the normal operation of the crushing roller 3 above.

[0091] To this end, the second motor 22 is used to provide power to the transmission gear 16, and the transmission gear 16 drives the chain 17 to rotate. At the same time, the flipping plate 10 is horizontally fixed outside the chain 17. Driven by the chain 17, the position of the flipping plate 10 is constantly moved. During the upward movement of the flipping plate 10 close to the mesh plate 18, the powder sliding down from the inclined mesh plate 18 is caught. As the flipping plate 10 moves, the powder will pass through the upper flow channel 15 together, and slide out from the lower channel 7 at the lower end and fall on the inclined plate 6. At the same time, the size of the flipping plate 10 matches the size of the inner side of the upper flow channel 15. The advantages of this component design are:

[0092] It can effectively solve the problem of powder accumulation on the mesh plate 18. At the same time, intermittent material dropping can prevent the discharge port 5 from being blocked. Secondly, the flipping plate 10 can assist in adjusting the angle of the mesh plate 18. Finally, when the flipping plate 10 and the baffle 11 contact each other, the baffle 11 hinged on the mesh plate 18 will be flipped upward. The flipped baffle 11 has the effect of blocking the powder, which can avoid the problem of excessive powder falling from the flipping plate 10.

[0093] When the turning plate 10 completes receiving the materials, some powder will adhere to the surface, so it needs to be cleaned in time.

[0094] To this end, when the flipping plate 10 rotates downward, the side that originally received the material faces downward. At this time, when the flipping plate 10 contacts the cleaning roller 9 that is rotated and arranged between the two first elastic ropes 8, the cleaning roller 9 will move along the surface of the flipping plate 10. In this way, through contact, the cleaning roller 9 with a rough surface will clean the powder adhered to the surface of the flipping plate 10. At the same time, the flipping plate 10 contacts the cleaning roller 9 during the return journey, changing the position of the cleaning roller 9. However, the first elastic ropes 8 connected on both sides of the flipping plate 10 are elastic, which will assist the cleaning roller 9 to return to its initial position and continue to clean the next flipping plate 10.

[0095] If the powder slides down the inclined screen plate 18 only by its own gravity, the amount of powder that slides down will be very small.

[0096] To this end, an elastic member consisting of a second elastic rope 131, a fixed head 132 and a third elastic rope 133 is provided on the side of the mesh plate 18 away from the flipping plate 10. When the flipping plate 10 contacts the mesh plate 18, the third elastic rope 133 is in a stretched state to store elastic potential energy. After the flipping plate 10 is separated from the mesh plate 18 and the external force is removed, the third elastic rope 133 will try to return to its original shape, that is, a straight line state when not subjected to force. In this process, the third elastic rope 133 will exceed its equilibrium position because it has a tendency to return to its original state. This movement exceeding the equilibrium position will cause the third elastic rope 133 and the second elastic rope 131 to vibrate until all the elastic potential energy is dissipated through internal friction damping. The jitter generated by this process can help the mesh plate 18 to smoothly transfer the powder to the flipping plate 10.
