Description

Technical Field

[0001] The invention relates to the technical field of rice milling machine rolling wheel speed control devices, and in particular to a rice milling machine rolling wheel speed control device specially used for processing selenium-enriched rice. Background Art

[0002] The existing process of selenium-rich rice milling is similar to that of ordinary rice milling. It mainly uses a grinding wheel to grind the rice grains to achieve the purposes of decomposing the rice grain structure, removing the rice grain skin and other impurities, and increasing the rice grain powder degree. During the grinding wheel adjustment process, the grinding wheel speed, grinding grain size, grinding wheel spacing and other parameters can be adjusted to achieve control of rice grain powder degree and fiber decomposition. At the same time, attention should also be paid to the maintenance and cleaning of the equipment to ensure the normal operation of the equipment and the stability of the rice milling quality.

[0003] However, the existing selenium-rich rice is not evenly fed during processing, resulting in too fast feeding. Excessive material will cause blockage in the material port due to the limited crushing speed of the machine. The blockage in the material port will not only cause the processing to be interrupted, but workers will need to spend time clearing the blockage. At the same time, if the material port is blocked, some selenium-rich rice may stay at high temperature for too long, resulting in burning or deterioration, thereby reducing the quality and taste of the product.

[0004] In addition, when in use, the selenium-rich rice milling machine usually relies on controlling the speed ratio of the motor to regulate the speed and direction of the grinding wheel. The motor usually has a specific speed range under a fixed design, which limits the speed regulation range that the grinding wheel can achieve and cannot meet certain processing requirements. Relying solely on motor drive may require complex control systems or mechanical devices to achieve direction changes and adjustments, which will make the equipment complicated, inconvenient to operate, and increase the risk of maintenance and failure.

[0005] Therefore, a rice milling wheel speed control device specially used for processing selenium-rich rice is proposed to solve the above problems. Summary of the invention

Through periodic flipping actions, the material can pass through the feeding port smoothly, reducing the possibility of blockage, thereby making the feeding more stable, and the stable feeding speed and uniform distribution can make the rice milling process more uniform, which is beneficial to improve the integrity and texture of rice grains and reduce the production of defective products.

[0051] In the prior art, the existing selenium-rich rice is not evenly fed during processing, resulting in too fast feeding. Excessive material will cause the material port to be blocked due to the limited machine rolling speed. The blockage of the material port will not only cause the processing process to be interrupted, but also require workers to spend time cleaning the blockage. At the same time, if the material port is blocked, some selenium-rich rice may stay at high temperature for too long, resulting in burning or deterioration, thereby reducing the quality and taste of the product.

By adjusting the conversion mechanism, the burden on the motor can be reduced and the service life of the motor can be extended.

[0052] For further examples, please refer to Figures 1 to 8 As shown:

[0053] The material unloading control mechanism 4 includes a cam 401, which is fixedly connected to the outer surface of the support plate 204, and a seesaw 402 is slidably connected to the outer surface of the cam 401. A tension spring 403 is fixedly connected to the side of the seesaw 402 close to the cam 401, and a fixed block 404 is fixedly connected to the end of the tension spring 403 away from the seesaw 402;

[0054] The bottom of the fixed block 404 is fixedly connected to the operating table 1, the end of the rocker 402 away from the cam 401 is fixedly connected to the transmission shaft 405, both ends of the transmission shaft 405 are rotatably connected to the material bucket 102, and the transmission shaft 405 is fixedly connected to the inner wall of the material bucket 102 with a material blocking plate 406;

[0055] in:

[0056] Switching the upper end rotating gear 305 to rotate, and through the rotation of the second gear 308, the toothed cylinder 103 starts to rotate in the opposite direction;

[0057] Switching the middle rotating gear 305 to rotate and rotating the first gear 307 will cause the toothed cylinder 103 to rotate slowly in the same direction;

[0058] Switching the lower end rotating gear 305 to rotate and rotating the first tripod 306 will cause the toothed cylinder 103 to rotate faster in the same direction;

[0059] In the prior art, the selenium-rich rice milling machine usually relies on controlling the speed ratio of the motor to regulate the speed and direction of the milling wheel when in use. The motor, under a fixed design, usually has a specific speed range, which limits the speed regulation range that the milling wheel can achieve and cannot meet certain processing requirements. Relying solely on motor drive may require a complex control system or mechanical device to achieve direction changes and adjustments, which will lead to complex equipment, inconvenient operation, and increased maintenance and failure risks. Compared with the prior art, through the implementation of this embodiment, the material blocking plate 406 is flipped regularly, which can not only ensure that the selenium-rich rice is fed uniformly at a stable rate, but also the flipping of the material blocking plate 406 can ensure the continuity and stability of the rice milling process, avoid poor rice milling effect caused by uneven incoming materials, and prevent material accumulation and blockage at the feeding port. Through periodic flipping action, the material can pass through the feeding port smoothly, reducing the possibility of blockage, thereby making the feeding more stable, and the stable feeding speed and uniform distribution can make the rice milling process more uniform, which is beneficial to improving the integrity and texture of rice grains and reducing the production of defective products.

[0060] Everything in the above example works like this:

[0061] In the initial state: the motor is not started, the tension spring 403 is not stretched, and the limit rod 210 is not stretched.

[0062] The following is a working process of the adjustable speed control mechanism 3 for adjusting and controlling the speed of the rice milling wheel 101 and the auxiliary steering mechanism 2 for the transmission conversion of the rice milling wheel 101.

[0063] First, Figure 8 As shown in the decomposition, refer to Figure 7 During operation, when the lower rotating gear 305 drives the first tripod 306 to start rotating in the clockwise direction, because the first meshing tooth 310 and the second meshing tooth 311 are both rotated and connected to the eccentric part of the first tripod 306, and at this time, because the first meshing tooth 310 is meshed with the first gear 307, when the first tripod 306 drives the first meshing tooth 310 to start rotating in the clockwise direction, because the meshing action of the first gear 307 causes the first meshing tooth 310 to start rotating in the clockwise direction on the first tripod 306, and because the second meshing tooth 311 is meshed with the tooth groove cylinder 103 and the second gear 308, when the first tripod 306 drives the first meshing tooth 310 to start rotating in the clockwise direction, 06 drives the second meshing tooth 311 to start rotating clockwise around the first tripod 306. At this time, due to the action of the tooth surface of the second gear 308 and the tooth surface of the second meshing tooth 311, the second meshing tooth 311 also starts to rotate clockwise. Since the first meshing tooth 310 and the second meshing tooth 311 are meshed with each other, when the first meshing tooth 310 and the second meshing tooth 311 both rotate clockwise, the first meshing tooth 310 and the second meshing tooth 311 are locked with each other, so that the first tripod 306 rotates to make the first gear 307, the second gear 308 and the tooth groove cylinder 103 rotate clockwise.

[0064] When the rotating tooth 305 in the middle drives the sleeve fixed on the first gear 307 to start rotating in the clockwise direction, because the middle part of the first gear 307 is sleeved on the second gear 308, the clockwise rotation of the first gear 307 will cause the first meshing tooth 310 to start rotating in the counterclockwise direction, and the counterclockwise rotation of the first meshing tooth 310 will cause the second meshing tooth 311 to start rotating in the clockwise direction, thereby driving the toothed cylinder 103 to start rotating in the clockwise direction;

[0065] When the upper rotating gear 305 drives the second gear 308 to start rotating clockwise, the second gear 308 rotates clockwise, causing the meshing second meshing teeth 311 to start rotating counterclockwise. The counterclockwise rotation of the second meshing teeth 311 on the first tripod 306 causes the meshing toothed cylinder 103 to also start rotating counterclockwise.

[0066] From the above, it can be seen that when switching different rotating teeth 305, the rotation direction and speed of the toothed cylinder 103 will be different;

[0067] Switching the upper end rotating gear 305 to rotate, and through the rotation of the second gear 308, the toothed cylinder 103 starts to rotate in the opposite direction;

[0068] Switching the middle rotating gear 305 to rotate and rotating the first gear 307 will cause the toothed cylinder 103 to rotate slowly in the same direction;

[0069] Switching the lower end rotating gear 305 to rotate and rotating the first tripod 306 will cause the toothed cylinder 103 to rotate faster in the same direction;

[0070] The speed control mechanism 3 is manually adjusted according to the requirements of rice milling. At this time, the adjusting handle 301 is manually turned to start rotating in the clockwise direction. The adjusting handle 301 is turned clockwise to cause the threaded rod 302 to start driving the threaded rod 302 to start sliding on the multi-functional bracket 104. At this time, because the universal shaft 207 and the gear guide plate 304 are fixed to each other, the slide plate 303 can drive the gear guide plate 304 to switch arbitrarily and engage with the rotating teeth 305 at different positions. At the same time, when the slide plate 303 slides downward, the reset spring 209 is stretched. At this time, the limit rod 210 starts to slide downward in the limit cylinder 208. When the operator turns the adjusting handle 301, the gear guide plate 304 engages with the rotating teeth 305 at the required position, and then the motor is started to rotate. Because the motor drive shaft is connected to the rotating wheel 201, as shown in FIG. Figure 6 As shown, when the rotating wheel 201 rotates, the transmission belt 202 causes the rotating rod 203 to start rotating in the same direction. At this time, the bevel teeth 205 far away from one end of the transmission belt 202 are meshed with the bevel teeth 206. The bevel teeth 205 are driven by the rotation of the rotating rod 203 to cause the bevel teeth 206 to start rotating in the opposite direction. At this time, the universal joint 207 is driven by the bevel teeth 206 to start rotating. The rotation of the universal joint 207 and the limiting action of the limiting rod 210 cause the gear guide plate 304 to start rotating, thereby driving the meshing rotating teeth 305 to start rotating through the rotation of the gear guide plate 304. By setting the adjustable speed control mechanism 3, the rotation direction of the rolling wheel can be appropriately adjusted according to the rough or damaged surface of the milled selenium-rich rice to improve the processing. The invention has the advantages of high efficiency and high gloss, and can also adjust the rotation speed of the rolling wheel according to different processing requirements (such as the accuracy and glossiness of rice grains). When the moisture content, hardness and other properties of the processed rice change, the speed can be adjusted as needed to adapt to the new material properties. The adjustable speed control mechanism 3 is set to accurately adjust the speed and direction of the rolling wheel according to different varieties of selenium-rich rice and processing requirements. By accurately adjusting the speed and direction of the rolling wheel, the rice milling process can be better controlled, the breakage and crushing of rice grains can be reduced, the integrity and glossiness of rice grains can be improved, and the quality and taste of rice can be improved. The fixed rotation direction and speed of the motor will cause uneven wear of the motor. By adjusting the conversion mechanism, the burden on the motor can be reduced and the service life of the motor can be extended.

[0071] Please refer to the above working process Figures 1 to 8 .

[0072] The following is the working process of the material feeding control mechanism 4 for controlling the material feeding of selenium-enriched rice:

[0073] like Figure 6 As shown, because the motor drive shaft is in transmission connection with the middle part of the rotating wheel 201, when the rotating wheel 201 rotates to drive the rotating rod 203 to rotate, because the cam 401 is fixedly connected to the outer surface of the rotating rod 203, the rotation of the rotating rod 203 will drive the cam 401 to start rotating in the same direction. At this time, because the seesaw 402 slides on the outer surface of the cam 401, and because a protrusion is provided on the fixed block 404, when the cam 401 rotates, the protrusion starts to squeeze the seesaw 402, and the seesaw 402 starts to slide to the left, and at the same time, the tension spring 403 fixed on the seesaw 402 starts to be stretched, as shown in FIG. Figure 3 As shown, when the seesaw 402 swings to the left, it will drive the transmission shaft 405 to rotate clockwise. At this time, the material blocking plate 406 fixed in the middle of the transmission shaft 405 begins to flip and open in the material hopper 102. Because the motor drive shaft is connected to the rotating wheel 201 for transmission, as the rotating wheel 201 continues to rotate, the material hopper 102 will flip and open and close back and forth, thereby intermittently controlling the material to fall. By setting the material discharge control mechanism 4, the material blocking plate 406 is regularly flipped back and forth, which not only allows the material to be evenly crushed on the road, but also prevents the material from being blocked by the rapid fall of the material during rice milling through the regular reciprocating flipping of the material blocking plate 406, thereby avoiding the poor rice milling effect caused by the uneven fall of the material, and preventing the material from accumulating and blocking at the discharge port. Through the periodic flipping action, the material can pass through the discharge port smoothly, reducing the possibility of blockage, thereby making the discharge more stable, and the stable feeding speed and uniform distribution can make the rice milling process more uniform, which is conducive to improving the integrity and texture of the rice grains and reducing the production of defective products.
