Technical Field

[0001] This utility model belongs to the field of rice huller design technology, and specifically relates to a rice huller that is easy to clean. Background Technology

[0002] A rice huller is a grain processing machine that removes the husk from paddy rice to produce brown rice. It removes the outer husk of the paddy rice, reducing grain breakage and surface damage, and preserving the brown rice as intact as possible.

[0003] Currently, Chinese patent CN221287953U, published on July 9, 2024, discloses a rice huller with easy-to-disassemble rubber rollers. It includes a machine housing, a fixed roller shaft mounted on the machine housing, a fixed rubber roller mounted on the fixed roller shaft, a movable roller shaft mounted on the machine housing, a moving rubber roller mounted on the movable roller shaft, and an adjusting cylinder. One end of the fixed roller shaft has a first fixed bearing seat mounted on the machine housing, and the other end has a second fixed bearing seat. One end of the movable roller shaft has a first movable bearing seat hinged to the machine housing, and the other end has a second movable bearing seat hinged to the machine housing. A maintenance door is hinged to one side of the machine housing. The maintenance door has a locking knob bolt for threaded connection to the machine housing to secure it. The maintenance door has an arc-shaped hole through which one end of the movable roller shaft passes and moves. The adjusting cylinder is hinged to the machine housing... Between the maintenance door and the end of the second movable bearing seat furthest from the hinge end; the second fixed bearing seat is installed on the maintenance door from the outside and cooperates with the fixed roller shaft during installation. A support roller for mounting one end of the second movable bearing seat is rotatably connected to the housing. The support roller is provided with an elastic element that drives the second movable bearing seat to move away from the movable roller shaft to separate it from the movable roller shaft. The support roller is provided with a locking mechanism that overcomes the elastic force of the elastic element and drives the second movable bearing seat to move closer to the movable roller shaft to cooperate with the movable roller shaft. The other end of the second movable bearing seat is detachably rotatably connected to the piston rod of the cylinder through a fork pin. After the second movable bearing seat is disconnected from the adjusting cylinder and the locking mechanism is released from overcoming the elastic force of the elastic element, the second movable bearing seat separates from the movable roller shaft and does not interfere with the opening and closing of the maintenance door after rotating outward.

[0004] Meanwhile, Chinese patent publication number CN115487891, published on December 20, 2022, discloses a double-body rice huller, including two machine bodies, a feeding hopper, a discharge plate, two rubber rollers, a discharge pipe, and an extraction pipe. The upper end of the feeding hopper is provided with a first guide plate that is inclined downwards. A drive roller is rotatably connected to one side of the feeding hopper and located at the lower end of the first guide plate. A drive motor with an output shaft connected to the drive roller is provided on the outer wall of the feeding hopper. A driven roller is rotatably connected to the feeding hopper and located on the side away from the drive roller. A rubber magnetic mesh belt is provided between the drive roller and the driven roller. A long slot is opened on the side wall of the feeding hopper and located on the side of the driven roller. An electromagnet with a suction force greater than that of the rubber magnetic mesh belt is provided on the outer wall of the feeding hopper and located at the position of the long slot. A collection box is provided below the driven roller and the electromagnet on the lower side of the long slot.

[0005] The rice enters the rice huller through the feed hopper and passes through two rubber rollers to remove the husks. The husks are then drawn away by the extraction pipe, leaving the brown rice to be discharged through the discharge pipe. However, when the rice huller stops, a small amount of brown rice may remain on the inner wall of the discharge pipe due to friction and gaps in the connection, which hinders the efficient discharge of brown rice from the discharge pipe. Utility Model Content

[0006] The purpose of this invention is to provide a rice huller that is easy to clean, and can use the air source of the drive cylinder to help empty the brown rice stuck in the discharge pipe.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. The drive cylinder needs to be supplied with air through the air source pipe when it is running. At this time, the first air pipe is split from the air source pipe to supply air to the drive cylinder, and the second air pipe is split to supply air to the connecting hose. The control is achieved by using a solenoid valve and a control ball valve. When the rice huller stops, the control ball valve can be opened and the cover plate can be removed from the long hole. At this time, the jet nozzle is inserted into the long hole. Then the high-pressure airflow ejected from the jet nozzle can act on the inner wall of the discharge hopper, thereby spraying off the brown rice attached to the inner wall of the discharge hopper. Finally, the air source of the drive cylinder can be used to help empty the brown rice stuck in the discharge pipe.

[0015] At the same time, when a lot of dust falls on the surface of the machine, the jet nozzle can be used to blow the surface of the machine to keep the surface of the machine clean.

[0016] 2. The spiral-shaped elastic storage part on the connecting hose facilitates the extension and retraction of the connecting hose, allowing the jet head to stably spray different positions on the machine body surface.

[0017] 3. When it is necessary to sample the brown rice in the discharge hopper, the round cover can be removed from the sampling port by moving the cover plate upwards, making it convenient to reach into the sampling port to perform the sampling operation;

[0018] 4. When sampling is required, move the cover plate up until the limiting buckle at the lower end of the elastic plate is embedded in the first buckle groove. At this time, the sampling port can be exposed to the outside. The height of the cover plate can be limited by the limiting buckle and the first buckle groove. Then, it is convenient to put your hand into the sampling port to perform the sampling operation.

[0019] 5. When it is necessary to blow the brown rice adhering to the inner wall of the discharge hopper, move the cover plate upward until the limiting buckle at the lower end of the elastic plate is embedded in the second buckle groove. At this time, the sampling port and the elongated hole can be exposed to the outside. The height of the cover plate can be limited by the limiting buckle and the second buckle groove. After the jet nozzle passes through the elongated hole and the sampling port, it can blow the inner wall of the discharge hopper. 6. The round cover is made of transparent material, so it is convenient to observe the working status inside the discharge hopper through the round cover. Attached Figure Description

The movable rubber roller 12 can swing by a swing arm. The drive cylinder 13 is installed on the side wall of the machine body 1. The drive cylinder 13 can connect to the swing arm of the movable rubber roller 12, thereby driving the movable rubber roller 12 to swing and change the gap between the movable rubber roller 12 and the fixed rubber roller 11. The air source pipe 2 is located on the lower side of the machine body 1 and is connected to an external air compressor (not shown in the figure) to connect to the drive cylinder 13. The feed hopper 14 is located at the upper end of the machine body 1, and the suction pipe 15 is located on one side of the machine body 1 to suck up the rice husks. The discharge bin 16 is located on the lower side of the machine body 1 to discharge the brown rice.

[0028] Reference Figure 1 , Figure 2 The end of the air source pipe 2 is connected to a first air pipe 21. The end of the first air pipe 21 away from the air source pipe 2 is connected to the drive cylinder 13. A solenoid valve 211 is installed on the first air pipe 21 and is fixed on the inner wall of the machine body 1. The end of the air source pipe 2 is also connected to a second air pipe 22 that extends out of the machine body 1. A control ball valve 221 is installed on the second air pipe 22. A connecting hose 222 is fixed at the end of the second air pipe 22 away from the air source pipe 2. A jet nozzle 223 is connected at the end of the connecting hose 222 away from the second air pipe 22. A spiral elastic storage part 2221 is integrally provided on the connecting hose 222.

[0029] Reference Figure 1 , Figure 3 , Figure 4The side wall of the discharge chamber 16 has a vertically extending elongated hole 161 for inserting the jet nozzle 223. An elongated cover plate 3 is installed on the elongated hole 161. A guide hole 162 is provided on the upper side of the discharge chamber 16 for the upper end of the cover plate 3 to pass through. A positioning plate 31 perpendicular to the cover plate 3 is integrally provided at the upper end of the cover plate 3. Simultaneously, a circular sampling port 163 for hand insertion is provided at the lower end of the elongated hole 161. A round cover 32, made of transparent plastic material, is integrally provided at the lower end of the cover plate 3 for sealing the sampling port 163. An elastic plate 164 is welded to the hopper 16 near the guide hole 162. The lower end of the elastic plate 164 is integrally provided with a limit buckle 1641. At the same time, a first buckle groove 33 is opened on the outer wall of the cover plate 3 for the limit buckle 1641 to be inserted. When the cover plate 3 moves upward and the limit buckle 1641 is inserted into the first buckle groove 33, the sampling port 163 is exposed to the outside.

When the cover plate 3 moves upward and the limit buckle 1641 is inserted into the second buckle groove 321, the sampling port 163 and the elongated hole 161 are exposed to the outside.

[0030] Principle: When the drive cylinder 13 is running, it needs to be supplied with air through the air source pipe 2. At this time, the first air pipe 21 is branched off from the air source pipe 2 to supply air to the drive cylinder 13, and the second air pipe 22 is branched off to supply air to the connecting hose 222. The solenoid valve 211 and the control ball valve 221 are used for control. When the rice huller stops, the control ball valve 221 can be opened and the cover plate 3 can be moved away from the elongated hole 161 until the limit buckle 1641 is embedded in the second buckle groove 321. At this time, the jet nozzle 223 is embedded in the elongated hole 161. Then the high-pressure airflow ejected from the jet nozzle 223 can act on the inner wall of the discharge bin 16, thereby spraying off the brown rice attached to the inner wall of the discharge bin 16. Finally, the air source of the drive cylinder 13 can be used to help empty the brown rice stuck in the discharge pipe.

[0031] At the same time, when a lot of dust falls on the surface of the machine body 1, the jet nozzle 223 can also be used to blow away the dust from the surface of the machine body 1, thereby keeping the surface of the machine body 1 clean.
