Description

Technical Field

[0001] The invention relates to the technical field of agricultural processing, in particular to a rice hulling device for a factory. Background Art

[0002] After the rice matures, it needs to be husked and then becomes the common rice on the table. Due to the current high rice yield, rice husking needs to be processed uninterruptedly through an assembly line, which mainly includes the steps of drying, husking, and rice husk separation.

[0003] In order to avoid too much broken rice during the hulling process, the surface of the hulling roller is usually made of rubber, but it is easy to cause wear during long-term work, and the rubber sleeve will have potholes, resulting in poor subsequent rice hulling effect, which requires rework and re-hulling, so the hulling roller needs to be replaced. In the prior art, when replacing the hulling roller, the hulling roller is usually manually removed and replaced with a new one, which is time-consuming and labor-intensive, and inefficient, and the replaced hulling roller can only be discarded, but in fact, the hulling roller is only damaged on the surface, and its internal structure is intact. If the entire hulling roller is discarded, it will cause waste.

[0018] After the group of support rods moving to the outside no longer supports the old rubber sleeve, the outer diameter of the support rods forming the circular array becomes smaller. The staff can easily remove the old rubber sleeve and easily put the new rubber sleeve on the support rod, which is convenient for the next replacement of the rubber sleeve.

The partition plate 33 divides the lower part of the discharge bin 3 into two left and right spaces. The suction fan 32 is located above the space on the left side of the discharge bin 3. The drop-out port formed between the dividing plate 31 and the bin wall of the discharge bin 3 is located above the space on the right side of the discharge bin 3. Two symmetrical shelling rollers 4 are rotatably connected inside the shelling bin 1. The shelling rollers 4 are driven to rotate by an external driving device, and the driving device is preferably a motor. The outer surfaces of the two shelling rollers 4 are sleeved with rubber sleeves 9. The outer surfaces of the two shelling rollers 4 are evenly provided with multiple replacement grooves 41 along the circumferential direction. The length direction of the replacement grooves 41 is parallel to the axial direction of the shelling rollers 4. Two symmetrical guide plates 42 are fixedly connected to the top of the inner cavity of the shelling bin 1. The guide plates 42 are located at the connection point between the delivery bin 2 and the shelling bin 1, and the guide plates 42 are located in the middle of the two shelling rollers 4. The top and bottom of the outer surface of the shelling bin 1 on the side with the opening are fixedly connected to a fixed frame 6. The top fixed frame 6 is provided with a guide groove 61, and the guide groove 61 is M-shaped. The two fixed frames 6 are provided with a stabilization groove 62, and a switching component is provided between the two fixed frames 6.

[0039] like Figures 4 to 9 As shown, the switching assembly includes two switching plates 71 slidably arranged between the two fixed frames 6. The shape of the switching plate 71 is adapted to the shape of the opening of the shelling bin 1, so the switching plate 71 can fit with the opening of the shelling bin 1 to seal the shelling bin 1. Four stabilizing rods 72 are fixedly connected to each switching plate 71. Two of the four stabilizing rods 72 form a group and are divided into two groups symmetrically up and down. A stabilizing block 73 is sleeved on each stabilizing rod 72. The stabilizing block 73 is slidably arranged in the stabilizing groove 62. The upper group of stabilizing rods 72 is slidably arranged in the stabilizing groove 62. In the fixed groove 62, a group of stabilizing rods 72 located below are slidably arranged in the stabilizing groove 62 of the fixed frame 6 below, a guide rod 74 is fixedly connected to the outer surface of the switching plate 71 near the upper part, and the middle part of the guide rod 74 is slidably arranged in the guide groove 61, and two servo motors 75 are fixedly connected to the upper surface of the top fixed frame 6, and a swing rod 76 is fixedly connected to the output shaft of the servo motor 75, and a slot 77 is opened at the end of the swing rod 76 away from the servo motor 75, and the top end of the guide rod 74 is slidably arranged in the slot 77, and each switching plate 71 is symmetrically opened with round openings, such as Figure 5 As shown, a rotating plate 78 is rotatably connected in the circular opening on the switching plate 71. The rotating plate 78 is circular and the middle part thereof is made of a transparent material. There are four rotating plates 78 in total. Figure 7As shown, a rolling groove 79 is provided on the inner surface of the circular opening of the switching plate 71, and a flange 710 is fixedly connected to the outer surface of the rotating plate 78. The flange 710 is annularly sleeved on the outer periphery of the rotating plate 78, and a circle of grooves is provided on the flange 710. A plurality of balls 711 are rollingly connected between the grooves of the flange 710 and the rolling grooves 79. The design of the balls 711 can make the rotating plate 78 rotate more smoothly.

[0040] like Figure 3 and Figures 6 to 9 As shown, the four rotating plates 78 are provided with replacement components for stretching open the rubber sleeve 9, and the replacement components include a plurality of support grooves 81 uniformly opened on the rotating plate 78 along the circumferential direction with the center of the rotating plate 78 as the center, and a support rod 82 is slidably connected in the support groove 81. The space of the replacement groove 41 can accommodate the support rod 82, and the end of the support rod 82 close to the support groove 81 is hinged with a push-pull rod 83, and the end of the push-pull rod 83 away from the support rod 82 is hinged with a link 84, and the side of the link 84 close to the rotating plate 78 and the position corresponding to each push-pull rod 83 are fixedly connected with an electric cylinder 85, and the telescopic axis of the electric cylinder 85 is fixedly connected to the rotating plate 78.

[0041] like Figure 3 and Figure 8 As shown, the delivery bin 2 is provided with a blocking component for blocking the communication port between the delivery bin 2 and the shelling bin 1, the blocking component includes two electric cylinders 51 symmetrically fixedly connected to the outer surface of the delivery bin 2, and two push-pull rods 52 are symmetrically rotatably connected to the output shaft of each electric cylinder 51, through grooves are provided on the shells of the delivery bin 2 and the shelling bin 1, and two blocking plates 54 are symmetrically slidably connected in the through grooves, and the two blocking plates 54 can block the communication port between the delivery bin 2 and the shelling bin 1 when the two blocking plates 54 are closed, and a connecting rod 53 is fixedly connected to one end of the two blocking plates 54 away from each other, and the two ends of each connecting rod 53 are respectively rotatably connected to the two push-pull rods 52 located on the same side thereof.

[0042] The following is the entire working process and working principle of the above embodiment:

[0043] The initial state is:

[0044] The electric cylinder 1 51 is in the energized state, the push-pull rod 1 52 pushes the connecting rod 53 to make the blocking plate 54 on both sides of the through groove, at this time the blocking plate 54 does not block the bottom of the delivery bin 2, the electric cylinder 2 85 is in the energized extended state, at this time the support rod 82 does not support the rubber sleeve 9, as shown in FIG. Figure 1 The switching plate 71 on the right side in the illustrated perspective is in contact with the shelling bin 1 .

[0045] The working status is:

[0046] The external drive device drives the shelling roller 4 to rotate inside the shelling bin 1, and the shelling roller 4 drives the rubber sleeve 9 to rotate in the opposite direction. At this time, the rice is put into the feeding bin 2, so that the rice falls downward into the shelling bin 1. Under the guidance of the guide plate 42, the rice falls into the gap between the two shelling rollers 4. During the rotation of the rubber sleeve 9, the rice can be shelled. The shelled rice husk and rice are discharged downward through the guidance of the dividing plate 31 in the discharge bin 3. Figure 3 As shown in the figure, after the suction fan 32 is started, the falling direction of the lighter rice husks will change, so that the rice husks will fall into the space on the left side of the partition plate 33 (as shown in FIG. Figure 3 The heavier rice will fall into the space on the right side of the partition plate 33, thereby separating the rice husk from the rice.

[0047] The blocking component blocks the connection between the delivery bin 2 and the shelling bin 1:

[0048] After husking the rice for a long time, pits and concave holes will appear on the surface of the rubber sleeve 9, resulting in incomplete husking of the rice, and most of the rice cannot be completely husked. At this time, when the rice is not husked, the staff can cut off the power of the rice husking equipment and the electric cylinder 51 at the same time. In the present embodiment, the electric cylinder 51 is a single-acting cylinder with a built-in spring. Therefore, after the electric cylinder 51 is powered off, its telescopic end will shrink under the action of the spring, and the contraction of the electric cylinder 51 drives the two symmetrically hinged push-pull rods 52 to move upward synchronously. The other ends of the two push-pull rods 52 respectively pull the two connecting rods 53 to slide, so that the two connecting rods 53 drive the two blocking plates 54 to gradually move toward the middle. At this time, the two blocking plates 54 enter the inside of the delivery bin 2, and the connection between the delivery bin 2 and the husking bin 1 is sealed, so that the rice entering the delivery bin 2 can be blocked in time, so as to avoid the delivery of rice in the subsequent replacement of the rubber sleeve 9, and avoid the direct discharge of rice without husking.

[0049] Replace the components to open the rubber sleeve 9:

[0050] When the electric cylinder 1 51 is powered off, the electric cylinder 2 85 will also be powered off synchronously. The electric cylinder 2 85 is a single-acting cylinder with a built-in spring. After all the electric cylinders 2 85 are powered off, their telescopic ends will shrink synchronously under the action of the spring. When the electric cylinder 2 85 shrinks, it drives the link 84 to move toward the side of the rotating plate 78. When the link 84 moves toward the side of the rotating plate 78, the end of the push-pull rod 2 83 connected to the link 84 also moves toward the rotating plate 78. At this time, the support rod 82 will slide along the support groove 81 away from the center with the midpoint of the rotating plate 78 as the center under the squeezing of the push-pull rod 2 83, so that the support rod 82 can be expanded outward, so as to support the rubber sleeve 9 sleeved on the outer surface of the shelling roller 4, so that the rubber sleeve 9 is stretched open.

[0051] A group of support rods 82 located outside the shelling bin 1 also simultaneously supports the new rubber sleeve 9 so that the new rubber sleeve 9 is stretched open, making it easier to smoothly sleeve the new rubber sleeve 9 onto the outer surface of the shelling roller 4 later.

[0052] The switching assembly changes the position of the new and old rubber sleeves 9:

[0053] Initially, Figure 4 The support rod 82 on the right side is located in the replacement slot 41 of the shelling roller 4. The staff turns on the two servo motors 75, and the servo motors 75 drive the swing rod 76 to rotate counterclockwise. Figure 4 As shown, when the swing rod 76 rotates counterclockwise, the swing rod 76 drives the guide rod 74 to slide in the guide groove 61. Specifically, Figure 4 The guide rod 74 on the right side drives the switching plate 71 which is in contact with the shelling bin 1 to move in a direction away from the shelling bin 1 first, so that the switching plate 71 is no longer in contact with the shelling bin 1. In this process, the switching plate 71 drives the stabilizing rod 72 to slide in the stabilizing block 73 to the side away from the shelling bin 1. Then, the guide rod 74 drives the switching plate 71 to move horizontally through the guide groove 61. At the same time, the lateral movement of the switching plate 71 drives the stabilizing block 73 to slide horizontally in the stabilizing groove 62 through the stabilizing rod 72. At this time, the switching plate 71 is no longer in contact with the shelling bin 1. The output shaft of the servo motor 75 drives the guide rod 74 to continue to move in the guide groove 61 in a direction away from the shelling bin 1 until the old rubber sleeve 9 is removed from the shelling bin 1. In the above movement, the switching plate 71 drives the old rubber sleeve 9 to move out of the shelling bin 1 through the support rod 82 on the replacement assembly, so as to achieve the effect of automatically disassembling the damaged rubber sleeve 9 and improve the disassembly efficiency of the rubber sleeve 9.

[0054] when Figure 4When the guide rod 74 on the left side moves to the middle position of the M-shaped guide groove 61, the servo motor 75 stops rotating. At this time, the positions of the two rubber sleeves 9 on the left side are opposite to the two shelling rollers 4. Then the staff observes whether the support rod 82 in the rubber sleeve 9 is aligned with the position of the replacement groove 41 in the shelling roller 4. Because the middle part of the rotating plate 78 is made of transparent material, the staff can observe the position of the support rod 82 and the replacement groove 41 through the transparent rotating plate 78. If they are not aligned, the rotating plate 78 is manually rotated until the support rod 82 is aligned with the position of the replacement groove 41. Then the servo motor 75 is started. The servo motor 75 rotates to drive the switching plate 71, the support rod 82 and the new rubber sleeve to approach the shelling bin 1 until the switching plate 71 fits the shelling bin 1. At this time, the support rod 82 is embedded in the replacement groove 41, and the new rubber sleeve 9 is put on the shelling roller 4. During the above movement, the switching plate 71 drives the new rubber sleeve 9 to move into the shelling bin 1 through the support rod 82 on the replacement assembly, thereby achieving the effect of automatically installing the new rubber sleeve 9, improving the replacement efficiency of the rubber sleeve 9, and saving manpower through automated disassembly and installation;

[0055] The movement of the two switching plates 71 is synchronous movement. Figure 4 The rubber sleeve 9 located on the left side moves to a position facing the shelling bin 1, and the rubber sleeve 9 originally located in the shelling bin 1 moves to the right side of the shelling bin 1;

[0056] After the rubber sleeve 9 is replaced, the staff can start the rice hulling machine, and the electric cylinder 2 85 and the electric cylinder 1 51 are energized at the same time. After the electric cylinder 2 85 is energized, it stretches and pushes the link 84 to move to the side away from the rotating plate 78. The link 84 pulls the support rod 82 through the push-pull rod 2 83 to move in the direction close to the center of the rotating plate 78 inside the support groove 81, so that the support rod 82 no longer supports the new rubber sleeve 9. After the new rubber sleeve 9 loses the supporting force of the support rod 82, the new rubber sleeve 9 will be tightened due to its own elastic properties. At this time, the new rubber sleeve 9 will be tightly sleeved on the outer surface of the hulling roller 4. At this time, since the support rod 82 is embedded in the replacement groove 41, the support rod 82 will be driven to rotate synchronously when the hulling roller 4 rotates, so that the support rod 82 drives the rotating plate 78 to rotate in the round mouth, thereby not affecting the normal rotation of the hulling roller 4.

[0057] When the old rubber sleeve 9 is replaced to the outside of the shelling bin 1, the same as the above working principle, the group of support rods 82 moved to the outside no longer support the old rubber sleeve 9, and the support rods 82 forming the circular array shrink inward. At this time, the staff can easily remove the old rubber sleeve 9 and easily put the new rubber sleeve 9 on the support rods 82 again, which is convenient for replacing the rubber sleeve 9 next time.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
