Problems solved by technology

Due to the relatively small shape and various shapes of crop seeds, the grain length observation of crop seeds is not only time-consuming, laborious, and difficult to measure, but also because the seeds with small grain size often have relatively large errors through manual measurement, and there is still a lack of methods for measuring the grain length of seeds. Uniform standards and effective equipment
Therefore, the determination of the grain size of crop seeds is facing difficulties and challenges

Embodiment 1

[0041] Such as Figure 1-4 , as shown in 6

[0042] A seed particle length measuring device, comprising a fixed shaft 1, a seed reel 2, a bottom support 3 fixedly arranged at both ends of the fixed shaft 1, a top support 4 and a sample pushing rod 5;

[0043] The seed reel 2 includes a first inner reel 6 arranged on the inner edge, and a shaft sleeve 7 is arranged on the first inner reel 6, and the seed reel 2 is axially sleeved on the On the fixed shaft 1, a first fixed clip 8 is provided on the shaft sleeve 7, and a second fixed clip 9 is provided on the bottom support 3; the reel 2 wraps the seeds to be measured along the first inner reel 6 Coiling system, and fix the upper end of the reel 2 through the first fixing clip 8 on the shaft sleeve 7, and fix the lower end of the reel 2 through the second fixing clip 9 of the bottom bracket 3;

[0044] Scales are respectively arranged on the shaft sleeve 7 side of the reel 2 and the upper and lower edges of the reel 2, and the ...

Embodiment 2

[0050] A kind of seed particle length measuring device as described in embodiment 1, its difference is that, described jacking 4 is provided with grid 4-2 through, and described push rod 5 pushes seed through grid 4-2 into the reel 2; the top bracket 4 and the bottom bracket 3 have the same shape.

[0051] One end of the pusher rod 5 is provided with a sponge ball 5-1, and the other end is provided with a hook 5-2. The sponge ball is used to push the seeds to the measurement position of the reel, and the hook is used to adjust the position of the seeds to facilitate accurate measurement.

Embodiment 3

[0053]A kind of seed grain length measuring device as described in embodiment 1, 2, its difference is that, described reel 2 also comprises the second inner reel 12 opposite to first inner reel 6, in the second inner reel The upper end of 12 is provided with a third fixing clip 11-1, and the fourth fixing clip 11-2 is arranged at the lower end of the second inner reel, and the outer edge of the reel is rolled by the second inner reel 12, and It is fixed by the third fixing clip 11 - 1 and the fourth fixing clip 11 - 2 provided on the second inner scroll 12 .

[0054] The rolling direction of the first inner scroll 6 is consistent with the rolling direction of the second inner scroll 12 .

Abstract

The invention relates to a seed grain length measuring device. The device comprises a fixing shaft, a seed winding cylinder, a bottom support, a top support and a sample pushing stick, the seed winding cylinder comprises a first inner side winding shaft arranged on the inner edge, a shaft sleeve is arranged on the first inner side winding shaft, the seed winding cylinder is axially arranged on the fixing shaft in a sleeved mode through the shaft sleeve, a first fixing clamp is arranged on the shaft sleeve, a second fixing clamp is arranged on the bottom support, the winding cylinder performs coating and winding on to-be-tested seeds along the first inner side winding shaft, the upper end of the winding cylinder is fixed through the first fixing clamp on the shaft sleeve, and the lower end of the winding cylinder is fixed through the second fixing clamp on the bottom support. The internal diameter of the seed winding cylinder is adjusted according to the size of the grain diameter of the seeds, the role in axially fixing the seeds is achieved, and the device is suitable for measuring the grain length of the seeds of different forms and sizes, operation is convenient and rapid, the structure is simple, and the work efficiency and the precision of seed grain length measuring are effectively improved.

Description

technical field [0001] The invention relates to a seed grain length measuring device and its application, belonging to the technical field of seed shape observation. Background technique [0002] The shape and size of crop seeds is an important indicator to characterize the quality of crop seeds. It not only affects the seed weight, germination ability and stress resistance characteristics, but also directly relates to the survival ability of seedlings and crop yield. Screening for large grain size and quality Good seeds are an important measure to improve the use efficiency of crop seeds and ensure the neat emergence of seedlings. Since the seeds of most crops are oblong, elliptical, and irregular shuttle-shaped, the grain length of crop seeds is considered to be one of the important indicators for measuring the size and quality of seeds. Due to the relatively small shape and various shapes of crop seeds, the grain length observation of crop seeds is not only time-consumin...
