The invention relates to the technical field of seed screening and quantitative subpackaging, in particular to a quantitative subpackaging machine for screening seeds for agricultural planting.

Background

Agriculture is an industry for obtaining products by artificial cultivation by utilizing growth and development rules of animals and plants, and belongs to the first industry, the science of research agriculture is agriculture, the working object of agriculture is living animals and plants, the obtained products are animals and plants, the agriculture is a basic industry for supporting national economic construction and development, the agriculture is an important industrial department in national economy, and is a department taking land resources as production objects, and the agriculture is an industry for producing food and industrial raw materials by cultivating animal and plant products.

Agriculture in the market at present is used for planting animals and plants, and comprises five industrial forms of planting industry, forestry industry, animal husbandry industry, fishery industry and subsidiary industry, wherein the agricultural planting is plant cultivation, comprises the cultivation of various crops, woods, fruit trees, flowers and plants, medicinal plants, ornamental plants and the like, and comprises grain crops, economic crops, vegetable crops, green manure crops, feed crops, pasture and the like.

Seeds are the reproductive system of seed plants and play an important role in continuing species. The seed is the structure grown by the ovule of the seed plant after fertilization, and generally comprises a seed coat, an embryo, an endosperm and the like.

Agricultural seeds require a large amount of high-quality seeds and have already formed a mature seed production and sale industry, and before the seeds are sold, the seeds mostly need to be sub-packaged into certain specifications, for example, according to quality, volume, weight and the like.

The seeds have different particle sizes and different corresponding volumes and qualities due to the influence of plant growth factors, so that a consumer purchasing the seeds has certain requirements on the purchased seeds, the specifications are uniform, and the specific reaction is that the sizes and the specifications of the seeds which are quantitatively subpackaged and subpackaged together are approximate in sales.

For example, chinese utility patent No. 201822247482.7 provides a partial shipment seed equipment, utilizes screw conveyer to carry the seed to the feed cylinder in, falls into the partial shipment bucket on the rotary platform by the second discharge gate of feed cylinder again, and after the partial shipment bucket was full, rotary platform rotated, sent next empty partial shipment bucket to the below of second discharge gate, and after all partial shipment buckets were filled with, the workman can utilize the travelling car to transport the partial shipment bucket of filling with appointed place.

However, the device is lack of screening treatment on seeds, and if seeds in different batches are mixed together, the sizes of the subsequently subpackaged seeds are still inconsistent; and the control to seed partial shipment volume is realized through solenoid valve cooperation partial shipment bucket, and this kind of mode through valve control partial shipment is also higher to the user requirement, easily causes great error.

Therefore, the inventor designs a quantitative racking machine for screening seeds for agricultural planting, and solves the problems.

the seeds thrown to the right are blocked by the right baffle 107, guided by the right seed guide plate 106 and fall to the inlet of the seed guide pipe 108;

when the crankshaft 203 rotates, the sleeve 204 drives the first rack 402 to move up and down through the push-pull rod 402, so as to drive the driven gear 406 to drive the second rotating shaft 405 to rotate forward and backward; the external thread shaft 501 at the right end of the second rotating shaft 405 synchronously rotates forward and reversely, and the threaded sleeve 502 drives the left partition 503 and the quantitative cavity to move left and right by utilizing the action of threads, and the baffle 506 moves along with the left partition 503 to intermittently block the outlet of the seed guide 108:
