Description

Quantitatively, seeder

Affiliated technical field

The present invention relates to a kind of agricultural seeding machine, specifically a kind of draw runner formula is quantitative, seeder.

Background technology

Development along with agriculture production technology, various agricultural machinery continue to bring out, but Seeder for crops, so far do not resolve mechanization sowing problem, especially the little seed crops of greengrocery are not also realized mechanical planting, and at present, sower roughly has two types, one class is the disc type sower, and another kind of is that machinery is cared for formula circular shaft formula planter, combined seed and fertilizer drill.Above-mentioned machinery is the agricultural production development, alleviate people's labour intensity, brought into play positive effect, but all there is complex structure in they, makes difficulty, traction power is big, cost is high, sowing is single, generally is used for the sowing of suitable drilling crop varieties such as wheat, is subjected to the influence of hauling speed speed, it is rare close inhomogeneous directly to have influence on sowing again, causes the waste of seed.

Before the present invention, application number is 962423734 patent application, discloses a kind of " slide type multifunctional seed drill ", and this utility model is made up of organic frame, metering system, transmission system, trench digging earthing system and five ones of handles.With manpower or animal power is power, adopts land wheel guide rod or transmission device, and the sowing system is by adjustable seed distributing groove, and the brush seeder of cellular type seeding board and skin is formed.By changing seeding board and seed distributing groove by different densities requirement bunch planting seed.Though this utility model reaches the seeding accuracy height, it is wide to broadcast the crop seeds variety range, only adapts to the program request single file and makes the species grain, have still that speed of drilling is slow, efficient is low, promote problems such as difficulty is big.

Summary of the invention

In order to solve existing sower complex structure, sow single, sow rare close unmanageable problem, the invention provides a kind of draw runner parallel-moving type quantitatively, the location multiplerow seeder, this machine can not only adapt to the sowing of multiple kinds of crops kind grain, can also be used for the sowing of greengrocery kind grain, this machine is simple in structure, easy to make, cheap, easy to operate, does not need the large-sized power traction.

The technical solution adopted for the present invention to solve the technical problems is: a kind of quantitatively positioning planting machine, by frame, transmission system, metering system, trench digging earth backing system forms, it is characterized in that: frame is established support bar (8 in (1), 12), it above the frame flat guide, guide rail is provided with seed dropping hole and slotted hole, discharging tube (2) is installed in the seed dropping hole, draw runner (4) is installed on the flat guide, be provided with auricle (9 below the draw runner, 10), auricle (9,10) be installed in the slotted hole respectively, auricle (9) is connected with an arm of rocking arm (7); another arm of rocking arm (7) is connected with adjusting yoke (20); the bearing pin (15) of rocking arm (7) is contained on the support bar (8); the other end of adjusting yoke (20) is connected with an end of poke rod (19); another termination of driving lever (19) and moving tooth (17) join; auricle (10) links to each other with rocking bar (11), and the rotating shaft of rocking bar (11) is contained on the support bar (12); Wheel shaft supported cart beam (24,21) welds with the lower frame of frame (1), and wheel shaft (22) is contained in the axis hole of car beam (24,21) front end, and the two ends of wheel shaft (22) is separately installed with wheel (18,13).

Described frame (1) is a quadrilateral frame, and frame mid portion is provided with cramp bar (8,12), and upper and lower is long limit, and upward long limit is a guide rail, and guide rail is provided with circular hole, and pipe (2) and slotted hole are planted by the row of being equipped with in the circular hole (falling), and auricle (9,10) is housed in the slotted hole.

Described transmission system is: moving tooth (17) is installed on the scroll wheel (18), driving lever (19) is installed on the driving lever bearing (16), one termination of driving lever (19) is that hinge is connected with an end of adjusting yoke (20), the other end of adjusting yoke (20) is that hinge is connected with an arm of "  " shape rocking arm (7), and another arm of "  " shape rocking arm (7) is connected for hinge with auricle (9).

Described metering system is: plant bag (6) and hang on Pig frame (5), the seeding mouth (28) of planting on sack and the machine joins, seeding mouth (28) is fixed on the supporting slice (26) on the Pig frame (5), discharging tube (2) is housed in the feed outlet on the frame (1), and the lower end of discharging tube (2) is the inclined-plane mouth of pipe.

Described trench digging earth backing system is: spacing compound soil plate (29) is installed below the frame (1), and the lower end that has hole, discharging tube (2) on the plate is passed in the hole from the spacing compound soil plate.

Under the effect of sower rocking arm drag link mechanism, the transverse horizontal that rotatablely moving of wheel is become the seeding draw runner moves, just in time the seed in the seeding mouth move to the seeding conduit above, and fall into automatically in the seeding conduit, automatically fall in the soil then, thus quantitative, the positioning planting of realization seed.Under the drive of transmission mechanism, the reciprocating motion of seeding draw runner has just formed the continuous action of sowing.The spacing in the rows of crop is to design definitely according to the wheel arc length degree that the moving tooth on the wheel is cut apart, and the size of sow a number and the seed of crop is determined by the feed outlet diameter that changes on the draw runner.If increase or reduce sowing line number (fabric width), the line-spacing width lengthening that determine according to prior design or shorten frame, and the feed outlet and the seeding unrounded number that correspondingly increase or reduce on discharging tube, the draw runner are realized.

The invention has the beneficial effects as follows, this sower is not only simple in structure, processing and fabricating is convenient, required drive is little, and except that power traction, people, livestock all can be drawn, foldable for storage also, can be widely used in crops such as soybean, peanut, corn, wheat, cotton, Peas, vegetables, flowers, rape, sesame and sieve fore-telling, Chinese cabbage, Hu Luobu seed quantitatively, location, multi-row seeding, neither can squeeze and hinder seed, can not cause the waste of seed again.
