CN203661559U - Low-density foxtail millet seeding machine - Google Patents

Abstract

The utility model discloses a low-density foxtail millet seeding machine which comprises a rack, a traction wheel, press wheels, a traction ring, a seed hopper, a support frame, furrowing ploughshares, seed shifting wheels, a seed shifting wheel axle, seed shifting chain wheels, a press wheel axle, a seed shifting driving wheel, a chain, hard seed pipes, soft seed pipes, seed shifting wheel grooves and seed outlets. According to a method that the seed shifting wheel grooves in the seed shifting wheels anticlockwise shift a small quantity of seeds to the seeds outlets continuously, the seed flow has no correlation with the quantity of seeds in the seed hopper, and small, continuous and uniform sowing density of foxtail millets is achieved, so that the thinning-out workload of the foxtail millets and the use quantity of seeds are reduced; and the low-density foxtail millet seeding machine is simple in structure, lower in manufacturing cost and easy to popularize and has a wide market prospect.

Description

Millet low-density sower

Technical field

The utility model relates to a kind of farm machinery, is particularly applicable to the device of millet low-density sowing.

Background technology

Millet is one of main coarse cereals of China, and millet contains abundant nutrient component, is therefore subject to extensively liking of people.Adopt for a long time the mode of high-density sowing for saving seedling from damage, however the necessary thinning of millet, millet thinning need to be bent knee and be squatted down, and squat and walk reach in thinning limit, limit, and its labour intensity is very large.And the mode sowing quantity of high-density sowing is also very large, causes unnecessary waste.For addressing the above problem, prior art has the report of millet single seed drill.But the particle of millet is very little, thousand kernel weight only has 2-3 gram, and therefore, seedling is very thin, a little less than pushing up native power, runs into after arid or soil compaction the surface of not being unearthed, paddy seedling top when unearthed.Also having a kind of seeding method is that part seed-grain is killed to its life, with traditional seeding machinary after planting, the millet evening ratio of emerging is lower, to reduce the workload of thinning.The method has reduced the labour intensity of millet thinning, but still has wasted many millet.

Summary of the invention

The purpose of this utility model is the deficiency existing for prior art, provides a kind of millet low sower, and its structure and simple to operate is easy to use, has reduced the thinning workload of millet, has reduced the consumption of seed-grain.

The technical solution adopted in the utility model is as follows: a kind of millet low-density sower, it comprises frame 1, traction wheel 2, press wheel 3, bail 4, seed bucket 5, bracing frame 6, ditching plow 7, pulls out kind of a wheel 8, pulls out kind of wheel shaft 9, pulls out kind of sprocket wheel 10, suppresses wheel shaft 11, pulls out kind of driving wheel 12, chain 13, soft seed pipe 14, pulls out kind of race 15, seed export 16, hard seed pipe 17.The below of the front end central authorities of described frame 1 connects traction wheel 2, the upper front of the front end central authorities of frame 1 connects bail 4, the both sides of frame 1 rear end connect suppression wheel shaft 11, two ends and the central authorities of suppression wheel shaft 11 are provided with press wheel 3, seed bucket 5 is being supported through bracing frame 6 in the top at the middle part of frame 1, on the crosspiece of the postmedian of frame 1 to having hard seed pipe 17.Described hard seed pipe 17 longitudinally aligns with press wheel 3, and the bottom of hard seed pipe 17 is provided with ditching plow 7, and ditching plow 7 is the low 2.5-3cm of plane with press wheel 3 compared with traction wheel 2.Described seed bucket 5 is interior is laterally provided with three by pulling out kind of sprocket wheel 10 through pulling out kind of the wheel 8 that pulls out that kind of wheel shaft 9 drives, and pulls out kind of sprocket wheel 10 and is driven by kind of the driving wheel 12 that pulls out being fixed on suppression wheel shaft 11 through chain 13.The back lower place at seed bucket 5 is provided with seed export 16 with pulling out kind of wheel 8 corresponding positions, through soft seed pipe 14, seed export 16 is communicated with hard seed pipe 17.Described kind of the centre for the neighboring of wheel 8 of pulling out, at interval of 0.5-1 cm be provided with length and width be 1 cm, the degree of depth be 0.5 cm pull out kind of race 15.

When operation, connect bail with tractor, drive operation plot into, seed is poured in seed bucket.When sower moves ahead, the ditching plow 2.5-3cm that buries, press wheel moves ahead to drive and pulls out kind of a driving wheel and rotate counterclockwise, pull out kind of a sprocket wheel through chain-driving, pull out kind of wheel shaft and pull out kind of a wheel and rotate counterclockwise, pull out in kind of race and be full of seed-grain, in the time pulling out kind wheel and rotate, pull out to by seed export pulling out seed in kind of race, seed flow is through soft seed pipe, hard seed pipe, be sown into soil from the rear portion of ditching plow, ditching plow soil natural below covers seed, press wheel subsequently passes from kind of a cunette, by the soil compaction of kind of cunette, seed-grain and soil are combined closely, be convenient to seed-grain and absorb soil moisture, germinate, emerge.

The beneficial effects of the utility model: (1) millet low-density of the present utility model sower relies on to pull out and pulls out kind of race method a small amount of, that pull out kind to seed export continuously counterclockwise on kind of wheel, make seed in the flow of seed and seed bucket number irrelevant, reach continuous, a small amount of, the uniform object of density of millet sowing, therefore, realized the effect that has reduced the thinning workload of millet and reduced the consumption of seed-grain; (2) millet low-density sower of the present utility model is simple in structure, and manufacturing cost is lower, is easy to promote, and has wide market prospects.
