Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a combined rice hulling and milling machine. Background Art

[0002] Rice is a finished product made from rice grains through various processes including cleaning, husking, milling, and finishing. The cleaning process involves using appropriate equipment, processes, and proper operation methods to remove impurities from the rice grains, thereby improving the quality of the finished rice.

[0003] Existing equipment for processing rice, for example, Chinese patent literature discloses a diversion structure of a rice husking and rice milling combination machine [application number: 201920115605.3; authorization announcement number: CN209530954U], which includes a frame, a rice husking and rice milling structure is provided on the top of the frame, a fan is provided in the frame, and an inclined air duct is also provided on the frame. The top of the air duct is connected to the fan, and the middle part of the air duct has a feed hole, and the feed hole is located below the discharge port of the rice husking and rice milling structure. The diversion structure includes a first diversion channel and a second diversion channel located at the bottom of the air duct, and a rotatable diversion plate is provided at the connection between the air duct, the first diversion channel and the second diversion channel. Rotating the diversion plate can connect the air duct with the first diversion channel or connect the air duct with the second diversion channel.

[0004] This type of rice husking and rice milling machine can complete rice husking and rice milling. However, this type of rice husking and rice milling machine has two flow channels. When processing brown rice and polished rice, it is necessary to switch between the first and second flow channels through a diversion structure, which is cumbersome to operate. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and propose a rice husking and rice milling combination machine, which solves the technical problem of how to make the combination machine easy to operate when switching between the rice husking and rice milling functions.

[0006] The objectives of the utility model can be achieved through the following technical solutions: a rice husking and rice milling combination machine comprises a chassis, a rice husking structure is provided on the upper part of the chassis, and a rice milling structure is provided on the lower part of the chassis, characterized in that the rice husking structure comprises a discharge pipe, the rice milling structure comprises a feeding funnel, a rotatable grinding disc, a material receiving box and a bran receiving box, the discharge pipe is connected with the feeding funnel, the discharge end of the feeding funnel is connected with the grinding disc, the feeding end of the feeding funnel is exposed outside the chassis, an opening and closing door is provided on the side of the grinding disc, the material receiving box is located below the grinding disc, the grinding disc can be connected with the material receiving box through the opening and closing door, the top of the bran receiving box is connected with the grinding disc, and the bottom of the bran receiving box is connected with a negative pressure fan.

[0007] During single hulling, the hulling mechanism hulls the rice to form brown rice, which then falls through a discharge pipe and a feed hopper onto the milling plate. The door opens, and the milling plate rotates at a low speed, generating centrifugal force that ejects the brown rice through the door into a receiving box. During single rice milling, since the feed end of the feed hopper is exposed outside the machine chassis, the brown rice can be directly transferred from the hopper to the milling plate. The door closes, and the milling plate rotates at a high speed to remove the hulls. The negative pressure fan activates, drawing the bran from the milling plate into the receiving box. Once processing is complete, the door opens again, and the milling plate rotates at a low speed, ejecting the polished rice through the door into the receiving box. During simultaneous hulling and rice milling, the brown rice from the hulling mechanism is transferred through the discharge pipe and feed hopper to the milling plate, where it is then processed according to the single rice milling process described above. The combined machine has only one channel, and the rotation speed of the grinding disc is controlled by a controller to realize rice husking and / or rice milling, and the operation is convenient.

[0008] In the aforementioned rice husking and milling machine, a channel housing is detachably attached to the chassis, into which the discharge pipe and the loading hopper are integrated. The discharge pipe, loading hopper, and channel housing form a one-piece structure. The provision of the channel housing enhances the secure installation of the discharge pipe and loading hopper, providing a high degree of rigidity.

[0009] In the aforementioned rice hulling and rice milling machine, the lower portion of the chassis protrudes forward relative to the upper portion of the chassis. A touch screen is provided above the protruding portion of the lower chassis. The channel housing is also located above the protruding portion of the lower chassis, and the touch screen is positioned adjacent to the channel housing. This structure allows the operator to better operate the touch screen and optimizes the layout of the rice hulling and rice milling machine.

[0010] In the aforementioned rice husking and milling machine, a drive motor is provided in the housing, and an output shaft of the drive motor is fixedly connected to one end of the door. The drive motor is capable of driving the door to rotate. The door can be opened and closed by controlling the start and stop of the drive motor via a controller, thereby facilitating operation.

[0011] In the above-mentioned rice hulling and rice milling combined machine, the top of the bran receiving box is connected to the grinding disc through a connecting channel.

[0012] In the aforementioned rice husking and milling machine, a discharge hopper is embedded in the machine housing. The upper edge of the opening and closing door is no higher than the upper edge of the discharge hopper. When the opening and closing door is open, the opening and closing door is located directly above the discharge hopper. The grinding disc is connected to the receiving box through the opening and closing door and the discharge hopper. With this structure, the rough rice or polished rice ejected by the grinding disc falls directly into the discharge hopper, or after hitting the opening and closing door, falls into the discharge hopper. This ensures that the grinding disc can completely fall into the receiving box when discharging rice.

[0013] In the aforementioned rice hulling and rice milling machine, the material receiving box and the bran receiving box are both embedded in the machine housing, the negative pressure fan is located directly below the grinding disc, the material receiving box is located below and in front of the grinding disc, the top of the bran receiving box is adjacent to the grinding disc, and the front of the bran receiving box is adjacent to the material receiving box. This structure provides a rational layout for the rice hulling and rice milling machine.

[0014] In the aforementioned rice huller and rice milling machine, the huller structure further includes a husk receiving box embedded in the machine housing, with the front portion of the husk receiving box positioned adjacent to the bran receiving box and positioned between the bran receiving box and the husk receiving box. This structure optimizes the layout of the rice huller and rice milling machine, with the husk receiving box used to receive rice husks.

[0015] Compared with the prior art, the rice husking and milling combined machine provided by the present invention has the following advantages:

[0016] 1. This rice husking and rice milling machine has only one channel. The controller controls the rotation speed of the grinding disc to realize rice husking and / or rice milling. The controller controls the opening and closing of the opening and closing door to realize material unloading, which is easy to operate.

[0017] 2. This rice hulling and rice milling combination machine can realize single rice hulling operation, single rice milling operation, and simultaneous operation of rice hulling and rice milling. It has three functions in one machine and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
