[0002] At present, in the existing rice appearance detection, a certain weight of rice needs to be evenly sprinkled on the measuring sieve, and then the rice is evenly brushed into the sieve holes with a brush, and the middle of the sieve is pressed with a finger to prevent the sieve from moving. Then, the sieve is gently picked up, and the brushed rice should be distributed in rows on the measuring board. Then, the measuring board is gently picked up, and the measuring board with the rice arranged is stably placed on the rice appearance detector, and the rice appearance detector is used to perform identification scanning to achieve accurate measurement of the rice appearance; However, in the process of the brush pushing the rice, on the one hand, the rice is easy to stick to the brush, and at the same time, a certain amount of rice and broken rice will still remain on the measuring sieve, affecting the accuracy and reliability of rice detection. At the same time, after the brush brushes the rice into the sieve hole, there is still a phenomenon that the rice is not flat but tilted and upright in the sieve hole.

One end of the two connecting shafts 52 is rotatably connected to the inner wall of the connecting shell 51, and the other ends of the two connecting shafts 52 pass through the connecting shell 51 and are connected to the driving member 7. There are multiple spreading members 6, and the multiple spreading members 6 are correspondingly distributed on the two connecting shafts 52. When the two connecting shafts 52 move to the sieve holes, the spreading members 6 assist in spreading the rice at the sieve holes.

[0019] The flattening member 6 includes a rotating block 61 and a matching pushing member 62. The rotating block 61 is fixedly sleeved on the outside of the connecting shaft 52, and moving openings 611 are respectively provided at both ends of the rotating block 61. In this embodiment, protrusions are provided on both sides of the rotating block 61, and the moving openings 611 are located at the protrusions. Two matching pushing members 62 are provided, and the two matching pushing members 62 are respectively connected to the two moving openings 611. A limiting opening 511 is provided at the bottom of the connecting shell 51 and corresponds to the position of the matching pushing member 62, and an opening 42 is provided at the bottom of the flattening shell 4 and corresponds to the position of the matching pushing member 62.

[0020] See also Figure 12 to Figure 13 and Fig.17 , the matching pusher 62 includes a synchronous shaft 621, a synchronous plate 622 and a flexible soft plate 623. In this embodiment, the flexible soft plate 623 is made of rubber material, so as not to cause wear to the rice. At the same time, the flexible soft plate 623 can be inserted into the sieve hole during the downward movement, so as to push the inclined or upright rice in the sieve hole, so that the rice can be spread flat in the sieve hole. The synchronous shaft 621 slides through the moving port 611, and a groove is provided on the top of the synchronous plate 622. The top of the synchronous plate 622 is rotatably sleeved on the outer side of the two ends of the synchronous shaft 621. The synchronous plate 622 slides through the limit port 511. The flexible soft plate 623 is fixedly installed on one side of the bottom of the synchronous plate 622, and the flexible plate is slidably connected to the opening 42; And when the flat shell 4 moves along the measuring sieve 3 , the multiple flexible soft boards 623 inside the flat shell 4 are all located inside the flat shell 4 , thereby not affecting the movement of the flat shell 4 .

[0021] The driving member 7 includes a driving gear 71, a synchronous rack 72 and an electric push rod 73. There are two driving gears 71, which are respectively fixedly sleeved on the outside of one end of the two connecting shafts 52.

The extension plate 74 is fixedly connected to the synchronous rack 72. Specific implementation process: When the flat shell 4 moves along the inside of the measuring sieve 3, the flat shell 4 pushes the rice through the flexible side plate 41, and the rice passing through the sieve holes will fall into the sieve holes in sequence, and the rice that has not fallen into the sieve holes continues to move along the bottom mesh plate 32 until all the rice falls into the sieve holes. At the same time, in the present invention, during the distance implementation process, generally 8 grams of rice are measured each time, and the number corresponding to 8 grams of rice is much smaller than the number of sieve holes, thereby preventing the phenomenon of rice stacking; At the same time, when the flat shell 4 moves to the corresponding snap-in hole 311 through the matching connection mechanism 8, the flat shell 4 pauses relative to the snap-in hole 311. At this time, the electric push rod 73 runs, further making the synchronous rack 72 move synchronously relative to the two driving gears 71. When the two driving gears 71 rotate synchronously, they respectively drive the multiple rotating blocks 61 thereon to rotate. When the rotating block 61 rotates, the rotating block 61 pulls the two synchronous shafts 621 on the rotating block 61 through the two moving openings 611 at both ends. At this time, the synchronous plate 622 is further limited by the limiting opening 511 to make the synchronous plate 622 It moves along the limit opening 511, and through the reciprocating operation of the electric push rod 73, the rotating block 61 is further made to reciprocate at a certain angle. In this embodiment, the swinging angle is preferably 45°, so that the two synchronous plates 622 on both sides of the rotating block 61 are alternately moved up and down along the limit opening 511, and when the synchronous plates 622 move up and down, the two flexible soft plates 623 at the bottom are further alternately moved up and down along the corresponding sieve holes, so as to achieve the effect of pushing and laying the rice at the sieve holes. When tilted rice is located at the sieve holes, the two flexible soft plates 623 push the tilted rice alternately, and the rice is subjected to external force, so that the rice is stably laid at the sieve holes.

[0025] See also Figures 6 to 10 The synchronous disengagement member 9 includes a synchronous member 91, an extrusion member 92 and a disengagement plate 93. One end of the synchronous member 91 is located inside the hand-held shell 82, and the linkage rod 83 is provided with a pushing inclined surface 831 at one end corresponding to the synchronous member 91.

[0026] The synchronous member 91 includes a first inclined block 911, a synchronous rod 912, a second inclined block 913, a limit plate 914 and a limit spring 915.

Specific implementation process: when the rice is evenly distributed at multiple sieve holes, the staff holds the hand-holding shell 82 with one hand and presses down the side of the measuring sieve 3 with the other hand to fix the measuring sieve 3 relatively to the measuring plate 2. Then, by pushing the hand-holding shell 82, the flat shell 4 is moved along the inside of the measuring sieve 3, so that the rice passing through the sieve holes falls into the sieve holes accordingly. When the clamping rods 812 on both sides of the flat shell 4 move to the clamping holes 311 respectively, under the reverse elastic force of the connecting spring 813, two further clamping rods 812 are clamped into the clamping holes 311 respectively, so that the flat shell 4 and the measuring sieve 3 are relatively fixed. When the two clamping rods 812 move along the clamping hole 311, the clamping rod 812 drives the reset rod 841 to move along the reset hole through the linkage rod 83 until the elastic pad 842 contacts the pressure sensor 843. Then, the pressure sensor 843 detects a signal, thereby sending the signal to the controller. Then, the controller controls the electric push rod 73 to operate, so that the flexible soft plate 623 at the sieve hole pushes and spreads the inclined rice. When the linkage rod 83 moves, the first inclined block 911, the synchronization rod 912 and the second inclined block 913 push the extrusion member 92, so that the extrusion member 92 drives the separation plate 93 to push and separate the rice adhered to the flexible side plate 41; Subsequently, the staff uses the thumb and index finger to squeeze the two reset rods 841 respectively, so that the reset rods 841 enter the interior of the hand-held shell 82 and the corresponding clamping rods 812 are respectively disengaged from the clamping holes 311. At this time, the electric push rod 73 stops running, and the staff continues to push the hand-held shell 82 to move along the inside of the measuring sieve 3 until it moves to the next set of clamping holes 311.

When the third inclined block 921 moves downward, the support rod 922 and the pulling plate 925 drive the separation plate 93 to move downward. When the separation plate 93 moves downward, the separation plate 93 moves along the outer side of the flexible side plate 41, thereby separating the rice stuck to the outer side of the flexible side plate 41, and preventing the rice from sticking to the flexible side plate 41. When the second inclined block 913 moves along the inside of the hand-held shell 82, the third inclined block 921 moves upward in the vertical direction, and then under the reverse elastic force of the positioning spring 924, the separation plate 93 further moves upward along the outer side of the flexible side plate 41, thereby facilitating the flexible side plate 41 to push the rice and make the rice fall into the sieve hole.
