Abstract

The utility model belongs to agricultural equipment and relates to a seeder used in raising rice seedlings, in particular to a duct lift type precision seeder. The duct lift type precision seeder comprises a seed box; a plurality of seed discharge ports are distributed at the bottom of the seed box; ducts equivalent to the seed discharge ports in number are distributed under the seed box; each seed discharge port is communicated with one duct through a lift pipe which is plugged and bushed in the seed discharge port and the duct; all lift pipes are fixed on a lift board together and can move up and down along with the lift board; an inlet at the upper end of the lift pipe is provided with a valve and a spring capable of leading the valve to be closed is arranged between the valve and the lift pipe; in the seed box, a shield case opened downwards is arranged above each seed discharge port; the inner side of the top of the shield case is provided with a downward vertical push rod; and when the lift pipe moves up, the push rod can push the valve open downwards. The duct lift type precision seeder can improve seeding speed and seeding uniformity.

Description

Conduit elevation (over-and-under) type precision quantitative seed drill

Technical field

The utility model belongs to farm equipment, relates to a kind of seeder that uses in raising rice seedlings, specifically is a kind of conduit elevation (over-and-under) type precision quantitative seed drill.

Background technology

The common a kind of alms bowl disc type seeder of employed seeder in raising rice seedlings at present, it is made up of small one and large one two plastic casings, capsule be placed on large in, two box bottom opening, horizontal relatively push-and-pull by two boxes, the perforate of two boxes bottom is overlapped or staggered, so make the seed that is placed in advance in the box according to the seedling cave of setting apart from sowing.The every at seeding time push-and-pull of this mode of operation is play and once all will manually be put into a certain amount of seed again in box, and the seed of putting into also needs manually to sweep equably with hairbrush the position in each hole, and the uniformity of its inefficiency, sowing also is difficult to guarantee.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of conduit elevation (over-and-under) type precision quantitative seed drill that can improve the speed of drilling and the sowing uniformity is provided.

Conduit elevation (over-and-under) type precision quantitative seed drill of the present utility model includes a kind case, the bottom of planting case is placed with a plurality of sowing ports, plant the case below and be placed with the conduit suitable with sowing port quantity, each sowing port is connected by the fall way of a sleeve in sowing port and conduit with a conduit, and the arrangement of conduit lower end outlet is corresponding with seedling cave distance; Fall way vertically is provided with, and each fall way together is fixed on the lifter plate and can moves with lifter plate is upper and lower; Porch, fall way upper end is provided with a valve, valve is hinged and can be around the upper and lower upset of jointed shaft by the tube wall of jointed shaft and fall way, the downward upset of valve can be opened the fall way inlet, valve upwards upset can also be provided with the spring that valve is closed with the sealing of fall way inlet between valve and the fall way; In kind of case, the top of each sowing port is provided with a downward opening cover box, and the inside top of cover box is provided with a push rod vertically downward, and push rod can back down above-mentioned valve downwards when fall way moves up.

Described conduit is made up of for three sections upper, middle and lower, and wherein epimere and hypomere are rigid pipe and are separately fixed on separately the installing plate, and the flexible pipe by the stage casing between upper and lower two sections is connected.

The utility model in use only needs all seeds kind of case of packing into, and with each seedling kind cave of conduit lower end aligned, lifter plate of lifting can be finished once sowing, has improved speed of drilling greatly; Simultaneously each acupuncture point seeding quantity can accurately determine by the space of valve top, conduit upper end, guaranteed the uniformity of sowing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

As shown in the figure, this seeder includes a kind case 1, the bottom of planting case is placed with a plurality of sowing ports 11, plant the case below and be placed with the conduit 2 suitable with sowing port quantity, each sowing port 11 is connected by the fall way 3 of a sleeve in sowing port and conduit with a conduit 2, and the arrangement of conduit lower end outlet is corresponding with seedling cave distance; Fall way 3 vertically is provided with, and each fall way together is fixed on the lifter plate 4 and can moves with lifter plate is upper and lower; Porch, fall way 3 upper end is provided with a valve 31, valve 31 is hinged and can be around the upper and lower upset of jointed shaft with the tube wall of fall way by jointed shaft 32, the downward upset of valve can be opened the fall way inlet, valve upwards upset can also be provided with the spring that valve is closed with the sealing of fall way inlet between valve and the fall way; In kind of case 1, the top of each sowing port is provided with a downward opening cover box 5, and the inside top of cover box is provided with a push rod 51 vertically downward, and push rod 51 can back down above-mentioned valve 31 downwards when fall way moves up.Each conduit 2 is made up of for three sections upper, middle and lower, and wherein epimere and hypomere are rigid pipe 21 and are separately fixed on separately the installing plate 22, and the flexible pipe 23 by the stage casing between upper and lower two sections is connected.

When the utility model uses, kind of the case 1 of earlier all seed A being packed into, with each seedling kind cave of conduit 2 lower end aligned, this moment, operate lifting plate 4 and each fall way 3 moved up, move up into cover box 5 on the fall way after, the push rod in the cover box backs down valve 31, making a part of seed that is deposited on the valve enter conduit by fall way also finally is drained in the seedling kind cave by conduit, then, move down lifter plate again and fall way is got back to initial position, finish and once sow and prepare to sow next time.
