Abstract
The invention discloses a work method of a small corn sowing machine, capable of automatically screening high quality corn seeds. The work method of the small corn sowing machine capable of automatically screening high quality corn seeds comprises three steps: conveying the corn seeds in a storage box into a first screening section of a reversed teeth vibration sieve in a corn grain cleaning mechanism, screening wizened corn seeds in the screening section, which fall into the storage box, then forwards conveying larger and more saturated corn seeds to a second screening section under push of reversed teeth, wherein the corn seeds enter a grain conveying pipeline after falling from the second screening section and enter an intermittent quantitative grain feeding mechanism from the grain conveying pipeline; conveying the corn seeds to a seed falling slide way at intervals, wherein the corn seeds fall into a ditched furrow, and the interval between corn seeds which fall at two adjacent times is same as that of the fertilizer.
Description
Technical field
The present invention relates to corn seeding machine technology, be specifically related to a kind of method of work of small corn planter.
Background technology
Along with the development of agricultural mechanization, the use of corn drill is more and more extensive.Corn drill refers to crop plants corn seed for sowing the planting machinery of object, corn drill have sowing evenly, the depth is consistent, line-spacing is stable, earthing is good, saving seed, operating efficiency high.Corn drill is divided into large-scale corn drill, medium-sized corn drill and small corn planter, and small corn planter is flexible because transporting, and is therefore widely used in mountain area, hilly country.
Existing small corn planter generally includes chassis, is arranged on the driving mechanism of chassis upper, Song Zhong mechanism and fertilizer can, be arranged on the road wheel that both sides, chassis are driven by driving mechanism, be arranged on the handrail at walking rear portion, chassis, be arranged on the cultivated plough of front portion, chassis.Wherein Song Zhong mechanism comprises seed storage case and structure of intermittently sowing, interval structure of sowing comprises and is positioned at seed storage box bottom and the carrier pipe communicated with seed storage box, the lower part outlet place of carrier pipe arranges the valve of timing interval opening and closing, is opened and closed realize sowing by the timing of valve.
The weak point that above-mentioned corn drill exists is: 1. because seed storage box directly communicates with structure of sowing, seed cleaning structure is not set, like this, have to prior to seeding manually clean shrivelled seed and high-quality full seed, the amount of labour is large, if seed screens before sowing, the shrivelled seed of some particles is together sowed in company with the high quality seed of full grains, due to shrivelled seed usually can not germinate or germinate after seedling also can undergrowth, then can affect emergence rate.2. sowed by the mode of timing keying carrier pipe valve, cannot guarantee that the granule number of each sowing is consistent, the situation generation even causing some sowing position not sowed, makes the output of seedling of later stage each sowing position uneven.3. existing small corn planter, especially the machine of frame-type chassis structure, usually only two road wheels are set in the position that the both sides on chassis are to the rear, when not sowing, cultivated plough is promoted to concordant with ground, anterior dependence is completely ploughed plough and is supported whole fuselage with the contact on ground, driven by the traction drive at rear portion or manpower and walk, sliding friction when Problems existing one is the friction due to cultivated plough and ground, frictional resistance is large, therefore walking resistance is large, speed is slow, two is because cultivated plough is not packed up, cultivated plough takes up room larger, therefore inconvenience is carried.
Summary of the invention
The invention is intended to provide a kind of can the method for work of small corn planter of automatic screening high-grade maize seed.
The method of work of the small corn planter in this programme, comprises the following steps:
The first step, sower starts, and walks forward, to be plowed trench digging by the cultivated plough in cultivated plow mechanism;
Second step, is positioned at the fertilizer can discharging at cultivated plow mechanism rear, and from fertilizer can, fertilizer out to fall fertilizer every a segment distance via fertilizer producing tube;
3rd step, corn seed in seed storage box is transported to the first sieve section of the pawl vibratory sieve in corn kernel dressing mechanism, in this sieve section, shrivelled corn seed sieve is fallen in container, then the comparatively large fuller corn seed of particle is fed forward to the second sieve section under the propelling movement of pawl, under the second sieve paragraph, enter into defeated grain pipeline, interval be entered into quantitatively to grain mechanism from defeated grain pipeline, quantitatively in slideway of sowing, corn seed is carried every a segment distance, corn seed drops in the ditch outputed, the interval of the corn seed of adjacent twice whereabouts is identical with the interval of fertilizer,
4th step, finally by the earthen backfill that the first trailing bar will plow, covers on corn seed, and sower continues to walk forward, repeats above-mentioned action, completes continuous sowing.
The beneficial effect of this method is as follows: because this programme is before corn seed sowing, include the step be separated with full corn seed by shrivelled corn seed, therefore shrivelled corn seed can be cleaned away, and sow high-grade maize seed, ensure emergence rate, and the puzzlement of artificial screening seed in early stage can be saved, save labor cost.
Further, in the third step, the method of work of interval dosing mechanism is: rotating shaft drives turntable rotation, when certain the profile of tooth grain groove on rotating disk turns to the import department of defeated grain pipeline and cover cap time, the ducted corn seed of defeated grain drops in this profile of tooth grain groove, rotating disk continues to rotate, in this process, cover on rotating disk periphery due to cover cap, therefore corn seed can not drop, until this profile of tooth grain groove on rotating disk rotates to the exit of cover cap, corn seed is transported to and sows in slideway, fall in the ditch outputed via slideway of sowing and sow.
In this programme, when the notch of profile of tooth hopper is not positioned at the import of cover cap, the cylindrical due to rotating disk has blocked import, and therefore the ducted corn seed of defeated grain can not go out grain.Owing to being by the profile of tooth grain groove feeding on rotating disk, as long as the size of each profile of tooth grain groove is made unanimously, just can realize interval quantitatively to grain.
Further, also comprise the steps: to have executed fertilizer in the ditch outputed between second step and the 3rd step after, on fertilizer, covered the soil of layer by the second trailing bar, and then sow on this layer of soil.Because seed sprouting back root part grows downwards, and fertilizer is just in time positioned at below seed, can supply more nutrition to root, fertilizer and corn seed is isolated simultaneously, prevent the seed sprouting initial stage from contacting with more fertilizer and occur burning bud phenomenon by one deck soil.
Further, after the 4th step, also comprise after sowing completes, the cultivated plough in cultivated plow mechanism is packed up be placed on walking chassis upper resettlement groove in, the front walking wheel that front portion, walking chassis is installed is put down, the step that whole machine is walked jointly by two rear walking wheels and front walking wheel.When not sowing, conveniently walking, cultivated plough can be packed up, and front walking wheel is put down, jointly being walked by rear walking wheel and front walking wheel, if during sowing, just front walking wheel can be packed up, in order to avoid impact is sowed, and cultivated plough is put down plow.
