[0025] In order to facilitate the understanding of the present invention, the present invention is further described below in conjunction with the accompanying drawings.
[0026] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "front", "rear", "left", "right", "up", "down", and "inside" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0027] like Figures 1 to 4 As shown, the rice husking and rice milling machine disclosed in the utility model is composed of a machine body 100, a rice husking mechanism 200, a rice milling mechanism 300, a weighing mechanism 400 and a switching mechanism 500; wherein the machine body 100 is used as the basic structure of the utility model, and the rice husking mechanism 200, the rice milling mechanism 300, the weighing mechanism 400 and the switching mechanism 500 are all installed on the machine body 100; the rice husking mechanism 200 is used to husking the grains to peel off the husks of the grains and make the husks of the grains The husk and brown rice are separated and transported to different processing mechanisms respectively; the rice milling mechanism 300 is used to mill the brown rice obtained after the husking process, so that the cortex and endosperm of the brown rice are separated to obtain polished rice; the weighing mechanism 400 is used to detect and weigh the polished rice obtained; the transfer mechanism 500 serves as a conveying component between the husking mechanism 200 and the rice milling mechanism 300, and transports the brown rice after the husking process of the husking mechanism 200 to the rice milling mechanism 300 for rice milling.
[0028] Specifically, Figure 2As shown, the rice husking mechanism 200 in the utility model includes a rice husking outlet 210, a feed collecting hopper 240, a rice husking assembly 250, a rice husking separation channel 260, a material gathering channel 270, a wind selection assembly 280 and a rice husk receiving box 290. The feed collecting hopper 240, the rice husking assembly 250, the rice husking separation channel 260 and the material gathering channel 270 are sequentially connected. The feeding collection hopper 240 is arranged at the top of the rice husking mechanism 200. The feeding collection hopper 240 is used to discharge and evenly distribute the grains, and the grains are transported to the rice husking assembly 250 inside the rice husking mechanism 200. The rice husking assembly 250 husks the received grains, and the rice husking assembly 250 peels the husks from the brown rice by the linear speed difference when the two rubber rollers rotate. The rice-brown separation channel 260 separates the husks and the brown rice by using the difference in the suspension speed of the materials. The top of the gathering channel 270 is the inlet end, and the bottom is the outlet end. The discharge port 210 is located at the outlet end at the bottom of the gathering channel 270. The gathering channel 270 is used to receive the separated brown rice and gather the brown rice to the huller discharge port 210, and enter the transfer mechanism 500 through the huller discharge port 210; the air separation component 280 uses the suction force generated when the fan rotates to suck away and separate the husks. The air separation component 280 has an air inlet end and an air outlet end. The husks are sucked into the air separation component 280 from the air inlet end of the air separation component 280, and then transported to the husk receiving box 290 through the air outlet end of the air separation component 280.
[0029] Specifically, Figure 2 and Figure 8 As shown, the rice milling mechanism 300 of the present invention comprises a rice milling feed port 310, a rice milling cover plate 330, a grinding sand disk 340, a driving assembly 350 and a grinding base 360. The rice milling feed port 310 is arranged on the rice milling cover plate 330, and is used to receive the brown rice delivered by the transfer mechanism 500. The brown rice obtained by the rice husking process of the rice husking mechanism 200 enters the interior of the rice milling mechanism 300 through the rice milling feed port 310 after being delivered by the transfer mechanism 500. The rice milling cover plate 330 is connected with the rice milling base 360 to form a grinding cavity structure for accommodating the grinding sand disk 340. The grinding cavity has a material input port and a material output port. The input port is connected with the rice milling feed port 310, and the material output port is connected with the weighing mechanism 400; the grinding sand plate 340 grinds the brown rice entering the grinding cavity by its own rotation to remove the surface layer of the brown rice; the driving component 350 is used to drive the grinding sand plate 340 to rotate, and the driving component 350 drives the grinding sand plate 340 to rotate at a high speed, so that the brown rice continuously flows and rotates in the grinding cavity, thereby generating friction with the sand grains of the grinding sand plate 340 to remove the surface material.
[0030] The weighing mechanism 400 in the present invention is used to measure the polished rice obtained after being processed by the rice milling mechanism 300. In addition, the present invention is also equipped with a corresponding control system to receive measurement information and output control instructions and detection information. The weighing mechanism 400 and the control system both adopt mature existing technologies, so they are not described here in detail.
[0031] like Figures 1 to 7 As described above, the structure of the transfer mechanism 500 is improved in the utility model, and the transfer mechanism 500 is composed of a shell 510 and a transfer channel 520. The transfer channel 520 adopts a channel structure with an external feed port 521, an internal feed port 522 and a transfer outlet 523; the external feed port 521 is used to receive external brown rice feed, the internal feed port 522 is used to receive the internal brown rice feed of the machine, and the transfer outlet 523 is used to transport the brown rice received by the transfer channel 520 to the rice milling mechanism 300; the internal feed port 522 is aligned and connected with the rice husking outlet 210, and the transfer outlet 523 is aligned and connected with the rice milling feed port 310, and the internal feed port 522 and the rice husking outlet 210 and the transfer outlet 523 and the rice milling feed port 310 are directly in contact and aligned, and can be set not to be fixedly connected to facilitate separation. By adopting the adapter mechanism 500 with two feed ports, the external feed port 521 and the internal feed port 522, the utility model can not only transport and mill the brown rice processed by the machine, but also transport and mill the brown rice samples sampled and tested by the machine and the brown rice processed by other machines. Figure 4 and Figure 7 As shown, the upper part of the transfer channel 520 is provided with two branch channels connected with the external feed port 521 and the internal feed port 522 respectively. The branch channel connected with the external feed port 521 is a tapered expansion channel, and the branch channel connected with the internal feed port 522 is an inclined straight pipe channel. Since the straight pipe channel connected with the internal feed port 522 is connected with the rice husking outlet 510, there will be no leakage problem, and its diameter does not need to be set too large, as long as it can be compatible with the rice husking outlet 510; and since the external feed port 521 is used to receive external feed, its feeding area can be increased, and a flaring structure is adopted to make the diameter of the external feed port 521 larger than that of the internal feed port 522.
[0032] Since the rice husker needs to be frequently inspected and repaired, in order to facilitate the inspection and repair of each component, the utility model improves the installation method of the adapter mechanism 500, and adopts a detachable method to install the adapter mechanism 500, such as a detachable connection method of threaded connection, snap connection or plug connection. The utility model adopts the snap connection as the preferred solution, such as Figure 6As shown, two opposite sides of the bottom of the shell 510 are provided with limit retaining edges 511, and the limit retaining edges 511 can be formed by bending the bottom edge of the shell 510, or a plurality of spaced limit blocks can be separately provided to form the limit retaining edges 511; Figure 8 As shown, a limiting convex edge 320 is provided on the rice milling cover plate 330 at the top of the rice milling mechanism 300, and the limiting convex edge 320 can be formed by horizontally extending the edge of the rice milling cover plate 330 outward. A limiting gap is formed between the limiting rib 511 and the bottom of the shell 510, and the width of the limiting gap is matched with the thickness of the limiting rib 420. When installing the adapter mechanism 500, align the limiting gap between the bottom of the shell 510 and the limiting rib 511 with the limiting rib 320 on the edge of the rice milling cover plate 330, push the shell 510 so that the limiting rib 320 is inserted into the limiting gap to complete the installation of the adapter mechanism 500; similarly, when disassembling the adapter mechanism 500, push the shell 510 in the opposite direction. With the above-mentioned installation structure, the transfer mechanism 500 is convenient to assemble and disassemble and easy to operate. When performing maintenance work, the transfer mechanism 500 can be quickly disassembled, so as to perform maintenance on the transfer mechanism 500 and the rice milling mechanism 300.
[0033] Furthermore, in order to improve the stability of the adapter mechanism 500 after installation, as Figure 2 and Figure 3 As shown, the utility model also installs magnetic blocks 110 with opposite magnetic poles on the body 100 and the shell 510 respectively; when the shell 510 of the switching mechanism 500 is snap-connected with the rice milling cover 330 of the rice milling mechanism 300, the shell 510 and the magnetic blocks 11 on the body 100 can attract each other, and the side of the shell 510 close to the body 100 is adsorbed on the body 100, thereby improving the stability of the entire switching mechanism 500 on the body 100. In order to make the shell 510 fit tightly with the body 100, as shown in FIG. Figure 6 As shown, the utility model provides a limiting groove 512 on the side of the shell 510 close to the body 100, and the limiting groove 512 corresponds to the position of the magnetic block 110; after the shell 510 is adsorbed by the magnetic block 110, the magnetic block 110 is embedded in the limiting groove 512, so that the installation gap between the contact surfaces of the shell 510 and the body 100 is reduced, and the fit is tighter; in addition, the limiting groove 512 can also form a limiting fit with the magnetic block 110 in the left and right directions, ensuring that the shell 510 will not shake, further improving the stability of the adapter mechanism 500 after overall installation.
[0034] like Figures 1 to 4As described above, in order to facilitate the maintenance of the rice husking mechanism 200 in the utility model, an opening is provided on the rice husking mechanism 200 to form an inspection window 220, through which the rice husking assembly 250 and other components inside the rice husking mechanism 200 can be inspected and maintained; and in order to prevent the brown rice or husk produced by the rice husking process inside the rice husking mechanism 200 from leaking out, the utility model is provided with an inspection baffle 230 to cover the inspection window 220, which can prevent external impurities from entering the rice husking mechanism 200 while blocking the leakage of internal materials and causing adverse effects on the rice husking work. Furthermore, a small transparent window can be provided on the inspection baffle 230 to observe the internal structure of the rice husking mechanism 200 in real time; the inspection baffle 230 can be fixed by bolt connection, snap connection, magnetic connection and other schemes to facilitate the disassembly and assembly of the inspection baffle 230, and in order to improve the convenience of disassembly and assembly in the utility model, the magnetic connection method is used as the preferred scheme.
