DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0027] See also Figure 1-Figure 5 As shown, the utility model is a rice grain screening device for rice processing, comprising an inclined base 1, a shell 2 is fixedly installed on the top of the inclined base 1, a screening mechanism 3 is slidably installed in the inner cavity of the shell 2, a power mechanism 4 is rotatably installed at one end of the screening mechanism 3, the power mechanism 4 is fixedly installed on the inclined base 1, a blast assembly 5 is rotatably installed at one end of the shell 2, a shelling mechanism 6 is fixedly installed on the top of the shell 2, and the screening mechanism 3 is set to be inclined at a set angle relative to the shell 2, and the inclination direction of the screening mechanism 3 is opposite to the inclination direction of the inclined base 1.
[0028] First, unhulled rice grains are put into the inner cavity of the hulling mechanism 6, and the hulling mechanism 6 is driven to rotate repeatedly, and then the unhulled rice grains are repeatedly beaten in the inner cavity of the hulling mechanism 6 to realize hulling of the rice grains. After the rice grains are husked, rice grains and rice grain shells will be produced, and the rice grains and rice grain shells will fall together onto the screening mechanism 3 below under the action of gravity. In the process of the rice grains and rice grain shells falling, the blowing component 5 is driven to generate wind force above the screening mechanism 3 to blow the lighter rice grain shells along the direction of the screening mechanism 3. The rice grains are separated from the rice grain shells by the hulling mechanism 6, and the rice grains are heated by the friction between the hulling mechanism 6. Therefore, the air blowing component 5 can cool the rice grains while separating the rice grains from the rice grain shells, thereby avoiding the risk of spontaneous combustion of the high-temperature rice grains directly entering the warehouse. The wind force generated by the air blowing component 5 can also blow the light and unqualified rice grains out of the device, thereby ensuring that the qualified rice grains are retained in the device.
[0029] At the same time, the heavier rice shells will not be affected by the wind force of the blowing assembly 5, and will fall onto the screening mechanism 3. At this time, the driving power mechanism 4 drives the rotatably installed screening mechanism 3 to perform repeated back and forth movements on the outer shell 2, so that the screening mechanism 3 can achieve an effect of screening the rice grains and the rice shells. Since the screening mechanism 3 is inclined at a certain angle relative to the outer shell 2, and the inclination direction of the screening mechanism 3 is opposite to the inclination direction of the inclined base 1, the screened rice grains will fall into the inclined inclined base 1 through the gaps in the screening mechanism 3 and go out of the device, while the rice shells will move along the screening mechanism 3 inclined in another direction and be discharged out of the device. By setting the inclination direction of the screening mechanism 3 to be opposite to the inclination direction of the inclined base 1, the rice grains and the rice shells can be completely separated.
[0030] Thus, by driving the air blowing assembly 5 to generate wind above the screening mechanism 3, the lighter rice grain husks are blown out of the device along the direction of the screening mechanism 3, and by driving the power mechanism 4 to drive the rotatably mounted screening mechanism 3 to perform repeated back and forth movements on the outer shell 2, the screening mechanism 3 can achieve an effect of screening the rice grains and the heavier rice grain husks, and by setting the inclination direction of the screening mechanism 3 to be opposite to the inclination direction of the inclined base 1, the rice grains and the rice grain husks are completely separated, thereby solving the problem of the need for secondary labor of the staff due to the lack of screening capability of the existing device, and increasing the practicality.
[0031] In one embodiment, for the above-mentioned screening mechanism 3, the screening mechanism 3 includes a screening mesh 301, the screening mesh 301 is slidably installed in the inner cavity of the outer shell 2, and the inclination direction of the screening mesh 301 is opposite to the inclination direction of the inclined base 1, and a rotating rod 302 is rotatably installed at one end of the screening mesh 301, and a rocking rod 303 is rotatably installed at the other end of the rotating rod 302.
[0032] The power mechanism 4 includes a driving motor 401, which is fixedly mounted on the tilting base 1, and a first pulley 402 is fixedly mounted on the output end of the driving motor 401;
[0033] A belt 403 is rotatably mounted on the circumferential surface of the first pulley 402 , and a second pulley 404 is rotatably mounted on one end of the belt 403 away from the first pulley 402 . The second pulley 404 is rotatably mounted on the tilting base 1 , and the second pulley 404 is rotatably mounted on the rocking arm 303 .
[0034] When the rice grains and the rice shells fall onto the screening mechanism 3 below under the action of gravity, the driving motor 401 will drive the first pulley 402 fixedly installed at the output end to rotate, and then the first pulley 402 will drive the belt 403 rotatably installed therewith to rotate, and then the belt 403 will drive the second pulley 404 rotatably installed therewith to rotate, and at the same time, the second pulley 404 will drive the rocking arm 303 fixedly installed therewith to rotate, and then the rocking arm 303 will drive the rotating rod 302 rotatably installed on the screening net 301 to rotate, and the screening net 301 is continuously rotated with the cooperation of the rocking arm 303 and the rotating rod 302, so as to realize The repeated back and forth movement of the screening net 301 enables the screening net 301 to achieve an effect of screening the rice grains and the rice grain shells. Since the inclination direction of the screening net 301 is opposite to the inclination direction of the inclined base 1, the screened rice grains will fall into the inclined inclined base 1 through the gaps in the screening net 301 and go out of the device, while the rice grain shells will move along the screening net 301 inclined in another direction and be discharged out of the device. By setting the inclination direction of the screening net 301 opposite to the inclination direction of the inclined base 1, the rice grains and the rice grain shells can be completely separated, thereby solving the problem that the existing device does not have the screening ability and requires the staff to do secondary labor, thereby increasing the practicality.
[0035] In one embodiment, for the above-mentioned blowing assembly 5, the blowing assembly 5 includes a servo motor 501, the servo motor 501 is fixedly installed on the outer shell 2, and the output end of the servo motor is fixedly installed with an output shaft 502, the output shaft 502 passes through and extends into the inner cavity of the outer shell 2, and a blower fan 503 is fixedly installed at one end of the output shaft 502 and located above the screening net 301.
[0036] During the falling process of rice grains and rice grain shells, the output end of the driving servo motor 501 drives the fixed output shaft 502, and at the same time, the output shaft 502 will drive the blower fan 503 fixedly installed therewith to rotate. Subsequently, due to the rotation of the blower fan 503, wind will be generated above the screening net 301 to blow the lighter rice grain shells out of the device along the direction of the screening net 301, thereby realizing the separation of rice grains and rice grain shells. In addition, after the rice grains are shelled by the shelling mechanism 6, the friction with the shelling mechanism 6 will generate high temperature. Therefore, the blower fan 503 can separate the rice grains from the rice grain shells while cooling the rice grains, thereby avoiding the risk of spontaneous combustion of high-temperature rice grains directly entering the warehouse, and the wind force generated by the blower fan 503 can also blow the lighter and unqualified rice grains out of the device, thereby ensuring that the qualified rice grains are retained in the device.
[0037] In one embodiment, for the above-mentioned shelling mechanism 6, the shelling mechanism 6 includes a feed port 601, a power motor 602 is fixedly installed at one end of the feed port 601, and a shelling roller 603 is fixedly installed at the output end of the power motor 602 and located in the inner cavity of the feed port 601.
[0038] First, unhulled rice grains are put into the inner cavity of the feed port 601. At the same time, the driving power motor 602 drives the fixedly installed hulling roller 603 to rotate. The rotation of the hulling roller 603 can collide and strike the unhulled rice grains in the inner cavity of the feed port 601, so that the hulling roller 603 can hull the rice grains, avoiding secondary labor of the staff, thereby saving the staff's time and energy.
[0039] In one embodiment, for the above-mentioned tilting base 1, support legs 101 are fixedly installed at the four corners of the bottom of the tilting base 1, and the lengths of the support legs 101 are different, so as to support the tilted tilting base 1.
[0040] The supporting legs 101 support the tilting base 1 to ensure that the device does not tilt when working.
[0041] In summary, with the aid of the above technical scheme of the utility model, the unhulled rice grains are first put into the inner cavity of the feed port 601, and at the same time, the driving power motor 602 drives the fixedly installed hulling roller 603 to rotate, and the rotation of the hulling roller 603 can collide and knock the unhulled rice grains in the inner cavity of the feed port 601, so that the hulling roller 603 hulls the rice grains. After the rice grains are hulled, rice grains and rice grain shells will be produced, and then the rice grains and rice grain shells will fall together onto the screening net 301 below under the action of gravity. In the process of the rice grains and rice grain shells falling, the output end of the driving servo motor 501 drives the output shaft 502 to, At the same time, the output shaft 502 will drive the blower fan 503 to rotate, and then due to the rotation of the blower fan 503, wind will be generated above the screening net 301 to blow the lighter rice grain shells out of the device along the direction of the screening net 301, so as to separate the rice grains from the rice grain shells. In addition, after the rice grains are husked by the hulling roller 603, the friction with the hulling roller 603 will generate high temperature, so the blower fan 503 can separate the rice grains from the rice grain shells and cool the rice grains at the same time, avoiding the risk of spontaneous combustion of high-temperature rice grains directly entering the warehouse, and the wind force generated by the blower fan 503 can also separate the lighter and unqualified rice grains. The rice grains are blown out of the device together, ensuring that qualified rice grains are retained in the device for screening. When the rice grains and rice shells fall onto the screening net 301 below under the action of gravity, the driving motor 401 at this time drives the first pulley 402 at the output end to rotate, and then the first pulley 402 drives the belt 403 to rotate, and then the belt 403 drives the second pulley 404 to rotate. At the same time, the second pulley 404 drives the rocking arm 303 to rotate, and then the rotating rod 302 on the screening net 301 is driven to rotate through the rocking arm 303. The screening net 301 is not rotated between the rocking arm 303 and the rotating rod 302. With the continuous rotation cooperation, the screening net 301 can achieve the effect of repeatedly moving back and forth, so that the screening net 301 can achieve the effect of screening the rice grains and the rice grain shells. Since the screening net 301 is inclined at a certain angle relative to the shell 2, and the inclination direction of the screening net 301 is opposite to the inclination direction of the inclined base 1, the screened rice grains will fall into the inclined inclined base 1 through the gaps in the screening net 301 and go out of the device, while the rice grain shells will move along the screening net 301 inclined in another direction and be discharged out of the device. By setting the inclination direction of the screening net 301 to be opposite to the inclination direction of the inclined base 1, the rice grains and the rice grain shells can be completely separated.
[0042] Through the above technical scheme, by driving the servo motor 501 to drive the rotation of the blower fan 503, wind will be generated above the screening net 301 to blow the lighter rice grain shells out of the device along the direction of the screening net 301, and the screening net 301 is continuously rotated and coordinated with the rocking arm 303 and the rotating rod 302, so that the screening net 301 can achieve an effect of screening rice grains and rice grain shells, and by setting the inclination direction of the screening net 301 opposite to the inclination direction of the inclined base 1, the rice grains and rice grain shells can be completely separated, thereby solving the problem that the existing device does not have the screening ability and requires secondary labor of the staff, thereby increasing the practicality.
