Description
Technical field
The utility model relates to a kind of agricultural machinery, specifically relates to a kind of vegetable-seed planter guide wheel push-down dispenser.
Background technology
Sowing of vegetable is the same with the sowing of other crops, has also experienced drilling, has broadcasted sowing the process of precision drilling.Just there are various types of vegetable-seed planters in Japan, Taiwan in the seventies and eighties in last century, but it is not suitable for the agronomy and the seed variety requirement of China's growing vegetables because of costing an arm and a leg, and fails to apply on a large scale in China.The domestic in recent years report that the development vegetable-seed planter is also arranged because of sowing factors such as kind is single, its performance is unreliable, is only being promoted among a small circle, up to the present, sowing of vegetable is still manual operations in the most of area of China, has both wasted seed, effort, time-consuming, and the growing vegetables family is very arduous.By artificial seeding's mode has three kinds, both broadcasted sowing, drilling and bunch planting, the bunch planting science, and nutrition is even, and illumination and ventilating economizes and kind also alleviates thinning labour intensity, but it is low to sow efficient.Existing seeding variety of components is various, as grooved pulley type, hole roller formula, disc type, pneumatic type and nail formula, duck-beak type etc., although performance is different, is used on the small size sowing vegetables facility, owing to many effects limit are difficult to realize.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, and a kind of guide wheel push-down dispenser that is used for vegetable-seed planter is provided.
The utility model vegetable-seed planter guide wheel push-down dispenser is achieved by following technical proposals: the described seed-box of the utility model vegetable-seed planter guide wheel push-down dispenser is fixed on the mid-stent top, preceding pack roller is fixed in the support front portion by roll shaft, the axle head of roll shaft is main drive gear fixedly, it is inboard and mesh with main drive gear that driven gear and sprocket coaxiality are fixed on the support roll shaft, guide wheel shaft is fixed in seed-box rear side on the support, be connected and fixed guide wheel and tower sprocket wheel by key respectively on the guide wheel shaft, back pack roller is fixed in the support rear portion by roll shaft, plough is fixed in mid-stent seed-box below, the fixedly connected sower handle of back-end support portion by the plough frame.Described seed-box bottom has circular sowing port, and described stifled kind of valve is fixed in seed-box exterior bottom feed outlet place by return spring, and the seeding adjustable plate is arranged between stifled kind of valve and the seed-box; Have diameter less than stifled kind mouthful of the oval slotted hole of seed-box sowing port with seed-box sowing port corresponding section on the described seeding adjustable plate.
The utility model vegetable-seed planter guide wheel push-down dispenser has following beneficial effect compared with prior art: the dispenser of the utility model setting is when facility advance, the rotation of preceding pack roller is done gyration with transmission of power to the guide wheel on the guide wheel shaft by gear drive, chain drive, contact with seeding guide rod afterbody by the convex-concave arc during guide wheel revolution, stifled kind of valve of seeding guide rod drive and seeding pull bar are moved reciprocatingly, and stifled kind of valve on the seeding guide rod constantly opens and closes sowing port and reaches bunch planting.When guide wheel turns to its convex arc when contacting with seeding guide rod afterbody, stifled kind of a valve cuts out sowing port and stops sowing, when guide wheel turns to its concave arc, the seeding guide rod is opened sowing port under the effect of two groups of spring forces, seed falls into grain tube and falls in the cave from sowing port under the drive of seeding pull bar, so just finishes a working cycles.The utility model vegetable-seed planter guide wheel push-down dispenser can be regulated amount of seed metering by adjusting mutual alignment between stifled kind of mouth of seed-box sowing port and adjustable plate; Stifled kind of a valve can accurately be controlled seeds fall grain number, can not cause the waste of seed; Dispenser also can be according to the spacing in the rows requirement of Different Crop kind, except changing the spacing in the rows of sowing by changing guide wheel, also transmission mechanism is designed to multipole speed change.The gear that the sprocket wheel that the Pulley mechanism that the spur gear that speed change gear is not waited by 2 numbers of teeth is formed and 4 diameters do not wait is formed, by the mutual installation site of change gear, and the combination of different sprocket wheels, can obtain six kinds of different gearratios.Therefore under same speed of drilling, guide wheel can obtain six kinds of different rotating speeds, has satisfied the agriculture requirement of different vegetable kind to spacing in the rows.The utility model reaches its bunch planting purpose according to the difference of the sub-shape of sow by the opening shape of changing the seeding adjustable plate.
The utility model vegetable-seed planter guide wheel push-down dispenser is simple in structure, and volume is little, and cost is low, and is easy to operate easy.The utility model vegetable-seed planter guide wheel push-down dispenser small size sowing of vegetable is specially adapted to the bunch planting of vegetable seeds such as wild cabbage, rape.
