Description

[0002] Wheat is a widely grown crop. Its seeds are a kind of cereal and a staple food worldwide. Wheat kernels are mainly used to make flour, while wheat husks can be used as feed. The shape of wheat kernels is an important criterion for measuring the quality of the wheat variety and finished product. Therefore, it is often necessary to measure the shape of the produced wheat kernels.

[0003] In the prior art, optical detection equipment is used to conduct targeted detection of each grain of wheat for high-precision measurement needs. However, the equipment cost of this solution is high, and it is difficult to popularize and use. In addition, it takes a long time to detect a large number of samples. Alternatively, a mechanical measurement solution is used. Mechanical measurement generally directly measures the length and diameter of the wheat grain shape with a ruler. However, due to the small size of wheat grains, whether it is independent measurement or multi-grain arrangement measurement, it will produce high operational difficulty due to the small volume, resulting in cumbersome measurement steps and long measurement time. Especially for the measurement of length, it is very easy to be unable to accurately measure the central axis due to the tilt of the wheat grains, and the measurement results are prone to large errors.

The wheat grain shape measuring device is used to measure the length of each of the multiple wheat grains 7 to be tested, and the process of measuring the sum of the diameters. When measuring, the measuring component 5 is first fixed on the bottom plate 1 and installed on the bottom of the pressing belt 2, and the measuring component 5 is locked by the long screw 3, and the pushing mechanism 4 is pulled out toward the front end. At this time, each wheat 7 to be tested can be placed in the measuring groove 18 inside the measuring component 5, and the pushing mechanism 4 can be used to translate to each wheat 7 to be tested, so as to realize the subsequent length measurement process. The present invention is used to perform size detection on a large number of wheat grain samples and meet the needs of rough detection.

[0027] In this embodiment, the pushing mechanism 4 includes a pushing plate 8 and a front end top plate 11, guide rods 9 are installed at both ends of the pushing plate 8, a plurality of insertion rods 10 are installed on one side of the pushing plate 8, and a front end top plate 11 is installed at the end of each insertion rod 10, and a handle 12 is installed on the other side of the pushing plate 8, each of the front end top plates 11 is aligned with the middle position of the measuring slot 18, the spacing between each of the front end top plates 11 is the same, and the front end top plate 11 is against the end of the wheat 7 to be measured, and multiple wheat grains are placed inside each measuring slot 18. With the help of the measuring slot 18, the automatic correction and positioning process of each wheat grain can be automatically realized, and then by controlling the external pushing mechanism 4, it can be directly Each wheat grain is pushed toward the rear end until it is pressed against the measuring component 5. The wheat grain pushes the measuring component 5 to realize the reading and measurement process of the length of each wheat grain, which simplifies the measurement steps and improves the efficiency of length and grain shape measurement of multiple wheat grains. Specifically, after the wheat 7 to be measured is placed inside the measuring groove 18, the entire pushing mechanism 4 can be pressed against the front end position of the wheat 7 to be measured by pushing the handle 12. This process will cause the insertion rod 10 at the rear end of the push plate 8 to be embedded into the interior of each measuring groove 18, and the front end top plate 11 at the rear end of the insertion rod 10 to press against the end of the wheat 7 to be measured, so that the wheat 7 to be measured can be moved toward the rear, realizing the linkage triggering process with the measuring component 5.

[0028] In this embodiment, the measuring assembly 5 includes a rear end top plate 21 and a frame 13, end plates 14 are provided at both ends of the frame 13, locking screw holes 15 are provided on the surface of the end plates 14, a plurality of measuring slots 18 are provided on the front side of the frame 13, and clamps 16 are installed on both sides of each measuring slot 18, a rubber clip 17 is attached to the inner side of the clamp 16, and a guide inclined plate 19 is provided at the front end of each rubber clip 17, and both sides of the wheat 7 to be measured are squeezed and clamped by the rubber clip 17, and in the process of measuring the length and the diameter, a limiting effect is provided for multiple positions of each wheat grain, thereby reducing the occurrence of each wheat grain in the measurement process. The probability of offset and misalignment reduces the difficulty of the entire grain shape measurement process and makes the measurement data finally obtained have higher accuracy. Specifically, a plurality of measuring slots 18 are provided in the measuring component 5. In the present embodiment, a total of ten measuring slots 18 are provided. When the wheat 7 to be measured is placed inside the measuring slot 18, it is inserted from the front end and guided by the guide inclined plates 19 on both sides of the wheat 7 to be measured, and the rubber clip strips 17 on both sides contact the two sides of the wheat 7 to be measured. The extrusion and limiting process of the wheat 7 to be measured can be completed, and the top of the wheat 7 to be measured is subjected to downward pressure through the extrusion belt, so that the wheat 7 to be measured can be prevented from sliding or offsetting during the subsequent measurement process.

[0029] In this embodiment, a plurality of supporting collars 20 are provided on the top of the frame 13, and a telescopic rod 23 is inserted inside the supporting collar 20. A rear end top plate 21 is installed at the front end of the telescopic rod 23, and a spring 22 is sleeved on the surface of the telescopic rod 23. A lower convex plate 24 is connected to the rear end bottom of the telescopic rod 23, one end of the spring 22 is fixedly connected to the surface of the supporting collar 20, and the other end of the spring 22 is fixedly connected to the end of the telescopic rod 23. The central axis of the front end top plate 11 and the rear end top plate 21 coincide with each other, and the rear end of the wheat 7 to be tested rests on the surface of the rear end top plate 21, the identification rod 25 is fixed to the bottom of the lower convex plate 24, and the bottom end of the identification rod 25 fits with the surface of the bottom plate 1, and each wheat 7 to be tested has a different size, so the position of each rear end top plate 21 will also be different, but the length of each wheat 7 to be tested is equal to the distance between the front end top plate 11 and the rear end top plate 21. Therefore, it is only necessary to read the data of the identification rod 25 at the end connected to the rear end top plate 21 pointing to the length scale line 26 to represent the length of the wheat 7 to be measured corresponding to the data. Specifically, by the above-mentioned holding handle 12, the pushing mechanism 4 is moved toward the rear end, and the end of the wheat 7 to be tested can be pushed backward through the front end top plate 11, so as to realize the process of moving the wheat 7 to be tested backward inside the measuring groove 18, until the rear end of the wheat 7 to be tested is pressed against the surface of the rear end top plate 21 and continues to move backward, and the rear end top plate 21, the telescopic rod 23, the lower convex plate 24 and the identification rod 25 can be driven to move with the help of the movement of the wheat 7 to be tested, so that the alignment position between the identification rod 25 and the length scale line 26 can change, and the pushing mechanism 4 can stop moving and pushing until the push plate 8 is pushed to fit the end of the guide sleeve 31. At this time, the contact position of the front end of each wheat 7 to be tested and the front end top plate 11 is on the same straight line, so the length data corresponding to each identification rod 25 and the length scale line 26 can represent the specific length of the corresponding wheat 7 to be tested, thereby realizing the length and grain shape data measurement process of each wheat 7 to be tested.
