Summary of the invention

The purpose of this utility model is: provide a kind of and can improve soil upturned soil flowability, reduce the power traction ridge upper seeding wheel machine that the pears post sticks foreign material.

Above-mentioned purpose is realized by following technical scheme: develop a kind of curved post power traction ridge upper seeding wheel machine, this sower also is to be made of parts such as frame, hanging device, seed manure case, plow standard, ploughs.Different is: the epimere of said plow standard is upright, and hypomere is the hook solid of protruding backward, and the latter end of crotch is equipped with plough.

The hanging device of said frame front is two direct rod shape draft arms that protract, the draft arm leading portion be provided with can with the chassis of tractor or hind axle by the rotating shaft mount hole of hinge mutually, the rear end of draft arm and the front-axle beam of frame be hinge mutually.

Between said two draft arms, a crossbeam is housed, there is a fore-stock that stretches out to the front upper place at crossbeam middle part, the frame front beam middle part is provided with an after-poppet that makes progress, fore-stock is relative with after-poppet, between a length-adjustable pull bar is housed.

Adopt the curved post power traction ridge upper seeding wheel machine of such scheme, because original upright plow standard has been become the crotch plow standard, improved the through performance of foreign material, solved the drawback that foreign material stick obstruction preferably, thereby improved the operation quality of sower, for plantation on the big field provides a kind of suitable facility.

Fig. 3 is the front view of parts pears post, and Fig. 4 is its left view;

Fig. 5 is the front view of parts plough, and Fig. 6 is its vertical view;

Fig. 7 is to use view.

Among the figure as seen: draft arm 1, shallow plough 2, seeding (fertilizer) pipe 3, frame 4, plough 5, bent plow standar 6, press wheel 7, mount hole 8, crossbeam 9, fore-stock 10, pull bar 11, after-poppet 12, front-axle beam 13, the back rest 14, crotch 15, carriage 16, ploughshare 17, earth separation plate 18, rotating shaft 19, angle modulation sheet 20.

Embodiment

As shown in the figure, this sower also has a rectangle frame 4 that is made of front-axle beam 13, the back rest 14 and side frame, clamp two shallow ploughs 2 on its front-axle beam 13, articulate seeding (fertilizer) pipe 3 above, above the back rest 14, on the position of staggering with shallow plough, 3 plow standards 6 are housed, one secondary plough 5 respectively is housed below each plow standard 6, on frame 4 back rest 14 two groups of press wheels 7 is housed also.Its main improvement as shown in Figure 3, Figure 4, plow standard 6 epimeres here are straight, hypomere is the crotch 15 of approximate half-circular.Compare with original vertical plow standard, this crotch plow standard has widened plow standard and ploughshare forward's distance, the Tu Fa that has ploughed is bumped against with plow standard after being quickened fully again, the be more convenient for throwing of Tu Fa is sent and is flowed, foreign material such as grass roots during soil is turned up soil rupture through strong impact, thereby make the scope that choking phenomenon reduces to permission that sticks.Should illustrate, this hooked plow standard adopted on original animal-drawn plough for a long time, different is that animal-drawn plough is to adopt the crotch structure long plow beam back, on the sower of tractor-drawn, if indiscriminately imitate the structure of animal power pears, not only can increase the length of sower, swing and imitate problems such as type difficulty increase but also plough body can occur, therefore existing sower has all adopted upright plow standard, the utility model combines upright plow standard and ancient crotch plough, respectively getting one section butt joint forms, both kept upright plow standard simple in structure, the characteristics of monolithic stability have possessed crotch again and have ploughed native upturned soil good fluidity, resistance is little, nonclogging advantage.

In addition, on mode of traction, similar type all is to set up the up and down hanger bracket implementation trifilar suspension of suspension plate and tractor back on the front-axle beam 13 of frame 4 separately, because the hanger bracket less stable of tractor, relatively with the such high load capacity work tool of multiplerow seeder, its integral rigidity is deficiency obviously.In order to address this problem, these facility are two direct rod shape draft arms 1 of hinge on the front-axle beam 13 of rectangle frame 4, the draft arm leading portion is provided with mount hole 8, two following hitch points of hanger bracket have been abandoned, and the direct hinge of tractor bottom girder or wheel shaft, frame 4 tops still with the draw bar of tractor hydraulic device control hinge mutually, the mode of this trifilar suspension had both kept original performance that articulates, and had increased stability again.

Owing to adopted the crotch plow standard, also brought the variation of plough 5 structures.Shown in Fig. 5,6, earth separation plate 18 above the ploughshare 17 of this plough extends significantly, and the front portion is divided into two sections, between link to each other with rotating shaft 19, adjustable angle separately is provided with a plurality of through holes above the angle modulation sheet 20 at the back side of earth separation plate, can with the carriage 16 that is fixed on the crotch back by bolt, thereby improved the service behaviour of earth separation plate 18, can in the scope of broad, arbitrarily adjust ridging height and thickness of earth covering.

Owing to installed the better front haulage arm 1 of rigidity additional, closely between two draft arms 1, installed firm crossbeam 9 additional, and the fore-stock 10 that on crossbeam 9, has been connected and has stretched to the front upper place, relative with the after-poppet 12 on frame 4 front-axle beams, there is screw pull bar 11 to draw mutually between two supports, adjust the length of pull bar 11, just can adjust the horizontal level of frame 4 and the embedded depth of plough 6, this compares more reliable and more stablely with original the adjustment by the tractor hydraulic device, and has alleviated the load of hydraulic means.
