[0052] like Figures 1 to 10As shown, further, a vertical rod 2051 is installed on the detection cover 101, and a positioning plate 205 is installed on the vertical rod 2051. A concave groove 2052 is opened on the positioning plate 205, and the concave groove 2052 is slidably connected to the connecting rod 204. The vertical rod 2051 serves to support the positioning plate 205.

[0053] Embodiment 3:

[0054] The difference between the above embodiment and this embodiment is that: Figures 1 to 10 As shown, a synchronous shaft 3022 is provided at the rotation center of the driven gear 3021, and the synchronous shaft 3022 movably penetrates the side wall of the detection cover 101, and the rotation centers of the synchronous shaft 3022 and the temporary storage cover 102 are connected to each other, and a torsion spring 3031 is sleeved on the rotating shaft 303, one end of the torsion spring 3031 is clamped on the side wall of the detection cover 101, and the other end of the torsion spring 3031 is clamped on the cover plate 1023. When the push plate 203 moves to the flipping groove 2022, the position containing the teeth of the driving gear 302 meshes with the driven gear 3021. At this time, the transmission shaft 2011 can drive the driving pulley 301 to rotate, and the driving pulley 301 drives the driven pulley 3011 to rotate through the belt 3012, and the driven pulley 3011 drives the coaxially connected driving gear 302 to rotate, and the driving gear 302 drives the meshing driven gear 3021 to rotate, and drives the entire temporary storage cover 102 to rotate and flip over through the synchronous shaft 3022, thereby achieving the purpose of changing the detection position.

[0055] like Figures 1 to 10 As shown, in a specific embodiment, a baffle 3053 is slidably disposed inside the reset cover 305, one end of the baffle 3053 is connected to the clamping rod 3051, and a reset spring 3052 is clamped between the other end of the baffle 3053 and the side wall of the reset cover 305, and the compression direction of the reset spring 3052 and the moving direction of the clamping rod 3051 are located on the same straight line. During the process of the top plate 3041 and the guide plate 304 moving upward synchronously, the clamping rod 3051 and the baffle 3053 are pushed to move inside the reset cover 305, and the reset spring 3052 is compressed at this time. When the top plate 3041 moves above the clamping rod 3051, the reset operation is performed by the reset spring 3052.

[0056] The present invention also discloses a detection method of a rice seed coat integrity detection device, the steps of which are as follows:

[0057] Step 1: Filling: adding an appropriate amount of test rice into the test cavity 1021 inside the temporary storage cover 102;

[0058] Step 2: Leveling the material, start the driving motor 2012, and drive the leveling roller 201 to rotate through the driving motor 2012, so that the position of the leveling groove 2021 on the leveling roller 201 changes, and the push plate 203 and the connecting rod 204 move horizontally. When the leveling plate 2042 on the connecting rod 204 moves to the top of the detection chamber 1021, the connecting rod 204 slides down along the concave groove 2052, and pushes the leveling plate 2042 to contact with the rice stacked at the bottom, and the rice becomes flat as the leveling plate 2042 moves;

[0059] Step 3: Bottom detection: the rice at the bottom of the temporary storage cover 102 is detected by the detector 1031;

[0060] Step 4: Cover closing and flipping detection, when the push plate 203 moves to the flipping groove 2022, the driving gear 302 drives the driven gear 3021 to rotate, and the driven gear 3021 drives the entire temporary storage cover 102 to rotate and flip, and in the flipping process, the guide plate 304 contacts the arc guide rail 3042, and the guide plate 304 rotates, thereby driving the rotating shaft 303 and the cover plate 1023 to flip, and at this time, the detector 1031 detects the rice inside the flipped temporary storage cover 102, completing the cover closing and flipping detection operation;

[0061] Step 5: Reset and unload. When the temporary storage cover 102 rotates and resets, the clamping rod 3051 and the arc guide rail 3042 are separated, and the cover 1023 opens automatically to complete the flipping operation. When the top plate 3041 moves to the top of the clamping rod 3051, at this time in the reset stage, the clamping rod 3051 pushes the top plate 3041 to rotate in the opposite direction, pushing the guide plate 304 to return to its initial state.

[0062] The implementation principle of a rice seed coat integrity detection device and method of this embodiment is as follows:

[0063] Adding a proper amount of test rice into the test chamber 1021 inside the temporary storage cover 102;

[0064] Then start the driving motor 2012, and the driving motor 2012 drives the transmission shaft 2011 to rotate. The transmission shaft 2011 is connected with a leveling roller 201, and the leveling roller 201 starts to rotate. The position of the combination groove 202 of the leveling roller 201 changes, resulting in a change in the position of the leveling groove 2021 at this time. A positioning slider 2037 is slidingly provided on the leveling groove 2021. At this time, the positioning slider 2037 can slide on the limiting limit rod 2035 to achieve the purpose of limiting. At this time, the position of the leveling groove 2021 changes, pushing the positioning slider 2037 to slide, and then the positioning spring 2036 can be squeezed, and the positioning spring 2036 is convenient for the later reset operation.

[0065] When the positioning slider 2037 slides, the positioning slider 2037 pushes the push plate 203 and the connecting rod 204 to move horizontally. When the flattening plate 2042 on the connecting rod 204 moves to the top of the detection chamber 1021, the connecting rod 204 will slide along the concave groove 2052, so that the overall height of the connecting rod 204 becomes lower, pushing the flattening plate 2042 to contact with the rice stacked at the bottom, and the rice becomes flat as the flattening plate 2042 moves.

[0066] When the connecting rod 204 slides, the connecting rod 204 pushes the extrusion slider 2034 to slide on the positioning slot 2031, thereby achieving the purpose of limiting the position. The extrusion slider 2034 itself slides on the guide rod 2032, which can squeeze the extrusion spring 2033 as a whole, and the extrusion spring 2033 can facilitate the subsequent resetting operation.

[0067] Then the operator detects the rice at the bottom of the temporary storage cover 102 through the detector 1031 .

[0068] When the push plate 203 moves to the flipping groove 2022, the position containing the teeth of the driving gear 302 meshes with the driven gear 3021. At this time, the transmission shaft 2011 can drive the driving pulley 301 to rotate, and the driving pulley 301 drives the driven pulley 3011 to rotate through the belt 3012, and the driven pulley 3011 drives the coaxially connected driving gear 302 to rotate, and the driving gear 302 drives the meshing driven gear 3021 to rotate, and drives the entire temporary storage cover 102 to rotate and flip over through the synchronous shaft 3022, thereby achieving the purpose of changing the detection position.

[0069] And in the process of turning over, Fig. 9 , Fig.10 As shown, when the synchronous shaft 3022 drives the temporary storage cover 102 to start rotating, the outer edge of the guide plate 304 on the side wall of the rotating shaft 303 contacts the arc guide rail 3042, and the guide plate 304 is squeezed and rotated. The guide plate 304 can then drive the cover plate 1023 to turn over, thereby protecting the rice inside the detection chamber 1021.

[0070] When the temporary storage cover 102 rotates 180 degrees, the detection operation is completed by the detector 1031.

[0071] When the temporary storage cover 102 continues to rotate, the clamping rod 3051 and the right arc-shaped guide rail 3042 are separated, and the cover plate 1023 is automatically opened under the action of the torsion spring 3031, so that the detection chamber 1021 is opened, which is convenient for unloading operation. As the movement continues, the top plate 3041 and the guide plate 304 move upward synchronously. When the top plate 3041 contacts the clamping rod 3051 on the inclined surface, the top plate 3041 is squeezed, and the top plate 3041 has the force to continue to flip, but At this time, the cover plate 1023 is in a vertical state. At this time, the rotation of the cover plate 1023 will squeeze the inner wall of the storage chamber 1011, so the cover plate 1023 will not rotate at this time, and the top plate 3041 will not rotate synchronously at this time, thereby pushing the locking rod 3051 and the baffle 3053 to move toward the inside of the reset cover 305, and compressing the reset spring 3052 at this time. When the top plate 3041 moves above the locking rod 3051, the reset operation is performed by the reset spring 3052.

[0072] At this time, in the resetting stage, the top plate 3041 is rotating in the opposite direction. At this time, the top clamping rod 3051 is not chamfered, so the clamping rod 3051 cannot be compressed inward at this time, and then the clamping rod 3051 pushes the top plate 3041 to rotate in the opposite direction. When the clamping rod 3051 and the guide plate 304 rotate to a specified angle, the guide plate 304 is inserted into the arc guide rail 3042 to facilitate the subsequent resetting operation and to facilitate the guide plate 304 to return to its initial state.
