[0003] In the prior art, a spiral feeding device is commonly used on the production line to conduct directional transportation operations on rice. However, in the actual use process, it is easy for the feeding speed to be too fast, exceeding the conveying capacity of the auger rod. The material cannot be conveyed out in time, and it will accumulate near the feeding port and then gradually spread in the conveying direction. Moreover, the material is also prone to blockage at the feeding pipe and the discharging pipe due to uneven rice particle sizes, thereby reducing the transportation efficiency of rice. The device needs to run for a longer time to convey the rice, or it is found that the rice conveying operation fails during the long-term operation of the device, resulting in an increase in energy consumption, which is not conducive to use.

Detailed implementation manners

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0031] Example 1:

[0032] As Figures 1 to 9 shown, a screw feeding device for rice processing according to an embodiment of the present invention includes a support base 1, a conveying cylinder 2 fixed to the top of the support base 1, a feeding pipe 31 communicatively fixed to one side of the top outer peripheral surface of the conveying cylinder 2, a discharging pipe 32 communicatively fixed to one side of the bottom outer peripheral surface of the conveying cylinder 2, a first auger rod conveying rod 7 rotatably connected to the middle position inside the conveying cylinder 2, and a feeding anti-blocking mechanism for assisting in conveying rice;

[0033] The feeding anti-blocking mechanism includes a feeding box 3 communicatively fixed to the top of the feeding pipe 31, a base 4 fixed to the other side of the bottom outer peripheral surface of the conveying cylinder 2, a motor 5 fixed to the bottom of the base 4, a connecting shaft 6 fixed to the output end of the motor 5, a guide frame 11 in the shape of a triangular prism fixed to the middle position inside the feeding box 3, a rotating shaft 8 rotatably connected to one side of the guide frame 11, a second auger rod conveying rod 12 rotatably connected to the bottom of the guide frame 11, two first bevel gears 9 fixedly sleeved on the upper and lower ends of the outer peripheral surface of the connecting shaft 6, second bevel gears 10 fixedly sleeved on the outer peripheral surfaces of the first auger rod conveying rod 7 and the rotating shaft 8 extending outside the conveying cylinder 2, and third bevel gears 13 fixedly sleeved on the second auger rod conveying rod 12 and the rotating shaft 8 extending into the inner cavity of the guide frame 11. The first bevel gear 9 is meshed with the adjacent second bevel gear 10. The bottom of the second auger rod conveying rod 12 extends into the inner cavity of the feeding pipe 31, and the two third bevel gears 13 are meshed with each other;

[0034] When the rice enters from the top of the feeding box 3, the motor 5 is started, so that the connecting shaft 6 rotates, driving the two first bevel gears 9 to rotate. Under the meshing action between the first bevel gear 9 and the second bevel gear 10 at the adjacent position, the first auger rod conveyor 7 rotates in the same direction as the rotating shaft 8. The first bevel gear 9, the second bevel gear 10 and the third bevel gear 13 have the same size and the same number of teeth. When the rotating shaft 8 rotates, under the meshing action between the two third bevel gears 13, the second auger rod conveyor 12 can rotate, and the rotation speed and direction of the second auger rod conveyor 12 are the same as those of the first auger rod conveyor 7. The spiral blades on the surfaces of the second auger rod conveyor 12 and the first auger rod conveyor 7 are both right-handed blades. By controlling the motor 5, the first auger rod conveyor 7 and the second auger rod conveyor 12 rotate counterclockwise, so that the rice entering the inner cavity of the feeding box 3 can be stably conveyed to the inner cavity of the conveying cylinder 2 under the action of the second auger rod conveyor 12, and under the action of the first auger rod conveyor 7, the rice is conveyed towards the discharge pipe 32 until it is discharged from the discharge pipe 32. During this process, since the rotation speeds of the second auger rod conveyor 12 and the first auger rod conveyor 7 are the same, it is ensured that the feeding speed of the rice entering the inner cavity of the conveying cylinder 2 from the feeding box 3 does not exceed the conveying capacity of the first auger rod conveyor 7, and the situation of rice accumulation and blockage at the conveying cylinder 2 will not occur.

[0035] As Figures 1 to 9 shown, the feeding anti-blocking mechanism further includes two rotating rods 16 rotatably connected to the inner cavity of the feeding box 3 at the position above the guide frame 11, a plurality of partition plates 17 fixedly arranged around the outer peripheral surface of the rotating rod 16 at equal intervals, a rotating shaft 14 rotatably connected to the inner cavity of the guide frame 11 at one end of the second auger rod conveyor 12, a fourth bevel gear 15 fixedly sleeved on the outer peripheral surface of the rotating shaft 14 at the position inside the guide frame 11, pulley wheels 18 fixedly sleeved on the outer peripheral surfaces of the two ends of the rotating shaft 14 extending outside the feeding box 3 and the outer peripheral surfaces of the rotating rods 16 extending outside the feeding box 3, and a connecting belt 19 sleeved between two adjacent pulley wheels 18. The fourth bevel gear 15 meshes with one of the third bevel gears 13;

[0036] When the rice enters the feed box 3 and the motor 5 is started, the meshing action between the fourth bevel gear 15 and one of the third bevel gears 13 orders the rotating shaft 14 to rotate, thereby driving two of the pulleys 18 to rotate, so that the two rotating rods 16 can rotate under the connection between the pulley 18 and the adjacent connecting belt 19, thereby driving the two sets of partitions 17 to make circular motion, so that the rice can be intermittently transported to the deep part of the inner cavity of the feed box 3, thereby avoiding the occurrence of blockage caused by excessive rice entering the inner cavity of the feed box 3 in a short time, and because the guide frame 11 is arranged in a triangular prism shape, the rice moved to the bottom plate of the partition 17 is conducted to both sides of the deep inner cavity of the feed box 3 under the action of the inclined surfaces on both sides of the guide frame 11, so that the rice can be evenly distributed in the deep inner cavity of the feed box 3, further preventing the occurrence of unstable rice delivery per unit time through the second auger rod conveying rod 12 due to uneven rice distribution.

[0037] Embodiment 2:

[0038] Although the above method solves the problem that the material cannot be transported out in time due to the excessively fast feeding exceeding the transporting capacity of the first auger conveying rod 7, and the material will accumulate near the feed box 3 and the conveying pipe 31 and then gradually spread in the transporting direction, in reality, during the process of the second auger conveying rod 12 transporting the rice from the bottom of the inner cavity of the feed box 3 through the conveying pipe 31 to the inside of the conveying cylinder 2, if the transported rice has uneven particle size or a certain viscosity, the fluidity of the rice will be poor. The batch of rice in the inner cavity of the feed box 3 will be directly transported by the second auger conveying rod 12 into the conveying pipe 31 with a smaller inner diameter, which will cause the second auger conveying rod 12 to be subjected to excessive resistance, resulting in the rice being blocked in the inner cavity of the conveying pipe 31.

[0039] So Figures 1 to 9 As shown, the feed anti-blocking mechanism also includes an air delivery component acting on the feed pipe 31, and the air delivery component includes a movable shaft 20 rotatably connected to one side of the conveying cylinder 2 and located at the top of the first auger rod conveying rod 7, a turntable 22 fixed to the top of the movable shaft 20, a first circular gear 21 fixedly sleeved on the outer circumference of the movable shaft 20 and at the middle position of the outer circumference of the connecting shaft 6, a movable frame 23 fitted on the top of the turntable 22, and a resistance rod 24 inserted in the inner cavity of the movable frame 23, the two first circular gears 21 are meshedly connected, and the bottom of the resistance rod 24 is fixed to the surface of the turntable 22.

[0040] When the motor 5 starts to rotate the connecting shaft 6, it can drive one of the first circular gears 21 to rotate. Thus, under the meshing action between the two first circular gears 21, the movable shaft 20 rotates, causing the turntable 22 to rotate, and the contact rod 24 to perform a circular motion. Then, under the contact action of the contact rod 24 on the inner cavity of the movable frame 23, a reciprocating motion force in a certain direction is applied to the movable frame 23.

[0041] As Figures 1 to 9 shown, the air delivery assembly further includes a plurality of annular pipes 25 sleeved on the outer peripheral surface of the feeding pipe 31, an air cylinder 26 fixedly connected to one side of the annular pipe 25, a movable plate 27 arranged on one side of the air cylinder 26, two connecting rods 28 fixed to one side of the movable frame 23, a piston rod 29 slidably inserted into the inner cavity of the air cylinder 26, an air inlet pipe 44 fixedly connected to one end of the air cylinder 26, and a plurality of guide pipes 30 fixedly connected to the inner peripheral surface of the annular pipe 25 and arranged in an equidistant and circumferentially distributed manner. The guide pipes 30 are connected to the inner cavity of the feeding pipe 31. A filter screen is fixed in the inner cavity of the guide pipes 30. One side of the piston rod 29 passes through the adjacent air cylinder 26 and is fixed to the surface of the movable plate 27. One side of the connecting rod 28 is fixed to the surface of the movable plate 27.

[0042] Since the piston rod 29 can only slide along the axial direction of the air cylinder 26, it can limit the movement trajectory of the movable plate 27. Thus, under the connection action of the connecting rod 28, it limits the movable frame 23, enabling the movable frame 23 to perform a reciprocating motion along the inclined direction of the conveying cylinder 2 under the contact action of the contact rod 24. As a result, the piston rod 29 can perform a reciprocating motion in the inner cavity of the air cylinder 26. One-way valves are added at the inner cavity of the air inlet pipe 44 and at the connection between the air cylinder 26 and the annular pipe 25, so that only air can enter the inner cavity of the air cylinder 26 at the air inlet pipe 44 and only air can enter the inner cavity of the annular pipe 25 at the connection between the air cylinder 26 and the annular pipe 25. Thus, when the piston rod 29 performs a reciprocating motion in the inner cavity of the air cylinder 26, the air pressure in the inner cavity of the air cylinder 26 changes, enabling air to enter the inner cavity of the annular pipe 25. Then, under the action of the guide pipes 30, air is conveyed into the inner cavity of the feeding pipe 31. After the air flows into the inner cavity of the feeding pipe 31, an air film can be formed between the rice and the inner wall of the second auger rod conveying rod 12, reducing mechanical contact friction, lowering equipment wear and energy consumption. Moreover, when the air flows through the gaps between the rice grains, a disturbing effect is generated, breaking up the lumps formed due to viscosity or electrostatic force, avoiding the risk of blockage caused by local accumulation, improving the fluidity of the loose rice. At the same time, under the blocking action of the filter screen in the inner cavity of the guide pipes 30, rice is prevented from entering the inner cavity of the guide pipes 30, avoiding the waste caused by rice remaining in the inner cavity of the guide pipes 30.

[0043] Embodiment Three:

[0044] The above method solves the problem that the material cannot be transported out in time due to the excessively fast feeding exceeding the transport capacity of the first auger conveying rod 7, and will accumulate near the feed box 3 and the conveying pipe 31 and then gradually spread in the transport direction, and the problem that the conveying pipe 31 is blocked due to uneven rice particle size or a certain viscosity. However, from a practical point of view, rice or impurities are likely to remain on the inner wall of the discharge pipe 32 when the material is discharged through the discharge pipe 32 for a long time, and the long-term accumulation and hardening will aggravate the subsequent discharge resistance.

[0045] So Figures 1 to 9 As shown, the feeding anti-blocking mechanism also includes a stripping assembly acting on the discharge pipe 32, the stripping assembly includes a rotating rod 33 rotatably connected to the other side of the conveying cylinder 2, a fifth bevel gear 34 fixedly sleeved on the first auger rod conveying rod 7 and extending to a position close to the outer circumference of the rotating rod 33 and the top of the outer circumference of the rotating rod 33, a second circular gear 35 fixedly sleeved on the bottom of the outer circumference of the rotating rod 33, a clamping seat 36 fixed to the bottom of the conveying cylinder 2 and located outside the discharge pipe 32, and a gear ring 37 rotatably connected to the middle position of the clamping seat 36, the second circular gear 35 and the gear ring 37 are meshingly connected, and the two fifth bevel gears 34 are meshingly connected;

[0046] When the first auger rod conveying rod 7 rotates, it can drive one of the fifth bevel gears 34 to rotate, so that the rotating rod 33 rotates under the meshing action between the two fifth bevel gears 34, thereby driving the second circular gear 35 to rotate and the meshing action between the second circular gear 35 and the ring gear 37 makes the ring gear 37 rotate at the middle position of the clamp seat 36.

[0047] like Figures 1 to 9 As shown, the stripping assembly also includes a plurality of sliding rods 40 slidably inserted on the inner circumference of the clamp seat 36 and arranged in an equidistant and surrounding manner, a resistance block 38 fixed to the inner circumference of the gear ring 37, a connecting block 39 fixed to the sliding rod 40 at a position in the inner cavity of the clamp seat 36, an impact head 43 fixed to one end of the sliding rod 40 near the discharge pipe 32, a fixed ring 41 fixedly sleeved on the outer circumference of the sliding rod 40, and a spring 42 sleeved on the outer circumference of the sliding rod 40 at a position on one side of the fixed ring 41, one end of the spring 42 is fixed to the surface of the fixed ring 41 at an adjacent position, and the other end of the spring 42 is fixed to the inner circumference of the clamp seat 36, and a rubber pad is glued to one end of the impact head 43 near the discharge pipe 32;

[0048] When the gear ring 37 rotates, it can drive the contact block 38 to do circular motion, so that the contact block 38 contacts the connecting block 39 in turn. Under the contact action of the contact block 38 and the connecting block 39, the sliding rod 40 can move towards the discharge pipe 32, so that the fixed ring 41 stretches the adjacent spring 42 to cause deformation, and the impact head 43 moves towards the discharge pipe 32 until it strikes the outer wall of the discharge pipe 32. When the contact block 38 moves away from the adjacent connecting block 39, the sliding rod 40 and the impact head 43 can be reset under the action of the resilience of the spring 42. When the contact block 38 rotates one circle, a plurality of impact heads 43 evenly distributed around the outer periphery of the discharge pipe 32 can strike the outer periphery of the discharge pipe 32 in turn, so as to assist the discharge pipe 32 to discharge rice to the outside of the conveying cylinder 2. Under the vibration generated by the impact head 43 striking the outside of the discharge pipe 32, the situation that rice or impurities remain on the inner wall of the discharge pipe 32 and aggravate the subsequent discharge resistance after long-term accumulation and hardening can be avoided.

Taking the perspective of the observer as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
