Plant seed selection device for agricultural experiments

Abstract

The invention belongs to the technical field of agriculture and particularly relates to a plant seed selection device for agricultural experiments. For the problem of insufficient screening caused byaccumulation of a large number of seeds during seed selection with water, the plant seed selection device comprises a seed selection box; and a first vibrating screen and a second vibrating screen which are obliquely arranged are arranged between the inner walls of two sides of the seed selection box through torsion springs, the first vibrating screen is positioned at the top of the second vibrating screen, a liquid inlet pipe is arranged on the outer wall of one side of the seed selection box through bolts, and a first liquid outlet pipe, a second liquid outlet pipe and a third liquid outletpipe are sequentially arranged on the outer wall of the side, away from the liquid inlet pipe, of the seed selection box from top to bottom through bolts. According to the plant seed selection device,the seeds are continuously added to a fixed cylinder from a feeding hopper, a blower is utilized to blow the air into the fixed cylinder, the dust is absorbed by a dust removal bag with the wind, theseeds enter the seed selection box from a discharging pipe, the saline water in the seed selection box is utilized to carry out selection with water, and the seed adding and screening are continuously carried out, so that insufficient selection with water caused by accumulation of a large number of seeds is avoided.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a plant seed selection device for agricultural experiments. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. The science of agriculture is agronomy. At this stage, agriculture is divided into two categories: plant cultivation and animal breeding. Usually, plants are planted by sowing seeds. to plant. [0003] Whether the grain is full or not is an important parameter for the quality of crop seeds. The empty seeds not only affect the vigor index of the seeds, but also affect the germination characteristics and survival ability of the seeds. Therefore, before agricultural planting or experimental seed planting, it is often necessary to check the seeds For screening operations, water selection is usually used. The seeds are placed in a suitable concentrat...
