[0020] In addition, the described features, structures or characteristics can be combined in any suitable manner in one or more example embodiments.

In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.
[0021] Example 1
[0022] like Figures 1-4 A broken rice separation device for rice processing includes a machine base 1, a filter cartridge 2, an anti-jamming mechanism 3 and a power mechanism 4.
[0023] The machine base 1 is placed on the ground and is used to support components such as the filter cartridge 2, the anti-jamming mechanism 3 and the power mechanism 4.
[0024] A plurality of filter holes are provided on the arc-shaped side wall of the filter cylinder 2. The diameters of the filter holes are screened and determined to be suitable for separating whole grain rice and broken rice.
[0025] The anti-jamming mechanism 3 is arranged on one side of the filter cylinder 2, generally at the top of the anti-jamming mechanism 3, and is used to use a brush needle to push out the rice grains stuck in the filter holes during movement, allowing the rice grains to return to the interior of the filter cylinder 2. The rice grains include whole rice grains and broken rice.
[0026] Specifically, the anti-stuck mechanism 3 includes a movable plate 31 and bristles. The side of the movable plate 31 is elastically slidably connected to the base 1 and can slide along the radial direction of the filter cartridge 2. The brush needle is fixed on the movable plate 31. When the movable plate 31 moves, the brush needle will be controlled to poke into the filter hole to poke the rice grains stuck in the filter hole back into the filter cartridge 2.
[0027] Preferably, the brush needles are arranged in an array on the movable plate 31 in piles, and the spacing between the brush needle piles is equal to the spacing between the filter holes, so that they can be accurately inserted into the filter holes of the filter cartridge 2, reducing the probability of the brush needles being bent.
[0028] Furthermore, the brush needles are made of a material that is not easy to bend and has a certain flexible deformation ability to reduce the probability of breakage, and the top of the brush needle is arc-shaped to reduce the probability of damaging rice grains. In this embodiment, the material of the brush needles is preferably carbon fiber reinforced plastic or glass fiber reinforced plastic, which is cheap, has good mechanical properties, and has both high tensile strength and high elastic modulus.
[0029] Furthermore, a clearance groove 32 is opened on the movable plate 31, and a supporting plate 33 is elastically slid in each clearance groove 32, and a brush pile is laid on the supporting plate 33. When the filter hole position and the bristle position on the filter cartridge 2 are not aligned, the spacing of the supporting plate 33 in the clearance groove 32 can be used as a distance compensation value to allow the supporting plate 33 to drive the brush pile to move along the clearance groove 32 and poke into the filter hole. At the same time, if the brush needle and the filter cartridge 2 rotate relative to each other, the movable ability of the supporting plate 33 in the clearance groove 32 can also provide a movement basis for the relative movement of the brush needle and the filter cartridge 2.
[0030] Preferably, the movable plate 31 is in an arc shape, and the center of curvature of the arc coincides with the center of curvature of the filter cartridge 2 .
[0031] Preferably, the movable plate 31 includes a center plate 311 and shoulder plates 312. The center plate 311 is elastically and slidably connected to the base 1. The shoulder plates 312 are connected to both sides of the center plate 311 for damped rotation. Brush needles are movably arranged on both the center plate 311 and the shoulder plates 312. If the size of the filter cartridge 2 varies, the angle between the center plate 311 and the shoulder plates 312 can be adjusted by bending the shoulder plates 312 on both sides of the center plate 311, so that the brush needles on the center plate 311 and the shoulder plates 312 fit more closely with the filter holes in the filter cartridge 2.
[0032] Example 2
[0033] like Figure 1 、 Figure 2 Furthermore, due to the movement mode of the anti-jamming mechanism 3, the designed power mechanism 4 needs to drive the anti-jamming mechanism 3 to perform linear motion.
[0034] Preferably, the power mechanism 4 includes a motor 41, a transmission wheel 42, a cam 43 and a tensioning wheel 44. The motor 41 is installed on the machine base 1, the end face of the filter cartridge 2 is fixed to the transmission wheel 42, and the cam 43 is rotatably connected to the machine base 1. The output shaft of the motor 41, the transmission wheel 42 and the cam 43 are connected by a belt drive, so that the output shaft of the motor 41 can drive the transmission wheel 42 and the cam 43 to rotate at the same time when rotating. In this case, the rotation speed of the cam 43 and the transmission wheel 42 is the same, and the cam 43 squeezes the movable plate 31 to make the movable plate 31 move up and down and allow the brush needle to poke into the filter hole.
[0035] Furthermore, a tensioning wheel 44 is elastically rotatably connected to the machine base 1, and the output shaft of the motor 41, the transmission wheel 42, the cam 43 and the tensioning wheel 44 are connected through a belt drive. The elastic rotation motion characteristics of the tensioning wheel 44 can keep the transmission belt in a tensioned state in real time.
[0036] Preferably, the power mechanism 4 includes a motor 41, a cam 43 and a gear set. The motor 41 is installed on the machine base 1. The motor 41 drives the filter cartridge 2 and the cam 43 to rotate in sequence through the gear set. The rotation rates of the filter cartridge 2 and the cam 43 can achieve the same or different control purposes according to the tooth ratio of the meshing gears.
[0037] In the above two driving modes, the cam 43 and the filter cartridge 2 are both driven to rotate by one power member, and the power flow process is relatively simple.
[0038] The following is a split drive solution, specifically:
[0039] Preferably, the power mechanism 4 includes a motor 41 and a cylinder, both of which are mounted on the base 1. The output shaft of the motor 41 drives the filter cartridge 2 to rotate via a belt drive or a gear drive. The telescopic rod of the cylinder is fixedly connected to the movable plate 31 to control the sliding of the anti-jamming mechanism 3 on the base 1. This split drive method requires additional design of the matching rhythm of the two power devices, or the cylinder can also be moved up and down according to human will when necessary. In this method, the movement of the anti-jamming mechanism 3 is more flexible.
[0040] The above two types of driving modes have their own similarities and differences. Users can make specific choices based on specific usage conditions. This embodiment does not limit them here.
[0041] Working principle of this utility model:
[0042] The present application designs a reciprocating anti-stuck mechanism 3, which drives the brush needle thereon to penetrate the filter holes of the filter cartridge 2 when necessary, and pushes the rice grains stuck in the filter holes back into the filter cartridge 2, thereby reducing the impact of filter hole blockage on the broken rice separation process. In addition, the movable ability of the brush needle can further improve the accuracy of the brush needle penetrating the filter hole and reduce the probability of the brush needle being accidentally bent.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
