By utilizing the ditching machine provided by the invention, ditching at one step and synchronous seeding at different depths of seed fertilizer are realized, and the working performance is excellent.

Description

Sower is used plough
Technical field
The present invention relates to a kind of sower and use plough, belong to agricultural machinery technological field.
Background technology
Plough is as the vitals of sower; Plough commonly used is the trench digging mode of fixed position; This mode is because penetrating angle is constant, and the sowing requirement that can only adapt under the single tillage condition as plough is for the no-tillage seeding of present popularization; Because penetrating angle fixedly is difficult to guarantee the trench digging degree of depth, limited the versatility that sower is used.Secondly; Because sowing at present mostly is seed manure with executing, and employing is in the ranks to apply fertilizer, and has not only increased the complexity of sower structure; And because plant, fertile plough spacing is less; The problem of blocking up of stalk, weeds before the no-tillage seeding process often plough occurs has had a strong impact on the operation quality of sower, sometimes even can not sow.In addition, far away owing in the ranks sowing apart from plant, also influenced fertilizer utilization ratio.
Break shovel type plough is the most frequently used plough of present domestic no-till maize machine, and it is stable that it has work quality, but easy blocking; And bad adaptability to the different surface situation; Though there is not the problem of blocking up in the disc type plough,, be difficult to guarantee for its trench digging degree of depth of different ground condition because that it goes into soil nature is poor.
Summary of the invention
The purpose of this invention is to provide a kind of adaptability that can overcome above-mentioned defective, improve sower, the sower of excellent working performance is used plough.Its technical scheme is:
Comprise sower crossbeam, plough and be connected the handle post between sower crossbeam and the plough; It is characterized in that: the upper end of handle post is to be hinged on the sower crossbeam by straight pin; The lower end is fixedly connected with plough; The sower crossbeam is provided with front limit piece and back limited block in the both sides that are positioned at the handle post, make when the handle post is put the front limit piece, under the tip of plough just in time is in straight pin, when the handle post is put back limited block by the front limit piece, the pendulum angle of handle post is 8~10 °; Set up regulating spring; The upper end of regulating spring is fixed on the sower crossbeam and is positioned at the front end of front limit piece, and the other end is hinged on the Lower Half of handle post, and the back lower place of plough is provided with wet soil backflow otch; The lower end of fertilizer guiding tube, grain conductor probes in the plough, and the fertilizer guiding tube defertilizing opening that is positioned at grain conductor front end, fertilizer guiding tube is lower than the sowing port of grain conductor.
Its operation principle is: the upper end of handle post is to be hinged on the sower crossbeam by straight pin; The lower end is fixedly connected with plough; Strain forward by reconciling spring at ordinary times; Make the handle post near the front limit piece, the tip of plough just in time be in straight pin under, guarantee that plough ploughing or the sowing in soft arable land with less penetrating angle; When sower when hard stub land carries out operation because face of land trench digging resistance increases, regulating spring is elongated, the moving plough of handle cornice is around 8~10 ° of straight pin backswing, the plough penetrating angle increases, and guarantees normally burying of plough, has guaranteed the uniformity of the trench digging degree of depth.
The present invention compared with prior art has following advantage:
1, the handle post can guarantee the soil nature of going into of soft, hard stub land table plough around the revolution of the straight pin on the sower crossbeam, has improved the adaptability of sower to the different work environment.
2, the adjusting of plough penetrating angle adopts regulating spring to spur the mode of hinged handle post, realizes the automatic adjusting of plough at different ground condition penetrating angle.
3, the plough that has wet soil backflow otch can be realized primary ditching, and the kind bed for fertilizer, two different depths of seed preparation helps improving fertilizer utilization ratio.
4, between the plough that has a wet soil backflow otch helps realizing kind, the fertilising control of bottom, satisfy the ferti-seeding requirement of different agriculture requirement crops.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Among the figure: 1, sower crossbeam 2, regulating spring 3, handle post 4, plough 5, front limit piece 6, back limited block 7, fertilizer guiding tube 8, grain conductor 9, straight pin 10, wet soil backflow otch
Embodiment
The upper end of handle post 3 is to be hinged on the sower crossbeam 1 by straight pin 9; The lower end is fixedly connected with plough 4; Sower crossbeam 1 is provided with front limit piece 5 and back limited block 6 in the both sides that are positioned at handle post 3; Make when handle post 3 is put front limit piece 5, under the tip of plough 4 just in time is in straight pin 9, when handle post 3 is put back limited block 6 by front limit piece 5, the pendulum angle of handle post 3 is 8~10 °, the upper end of regulating spring 2 is fixed on the sower crossbeam 1 and is positioned at the front end of front limit piece 5; The other end is hinged on the Lower Half of handle post 3; The back lower place of plough 4 is provided with wet soil backflow otch 10, and the lower end of fertilizer guiding tube 7, grain conductor 8 probes in the plough 4, and fertilizer guiding tube 7 defertilizing opening that is positioned at grain conductor 8 front ends, fertilizer guiding tube 7 is lower than the sowing port of grain conductor 8.
During work, the plough 4 that has wet soil backflow otch 10 is after kind of ditch is left on the face of land, and fertilizer guiding tube 7 at first imports bottom of trench with fertilizer, realizes than the fertilising at the bottom of the zanjon; Wet soil gets in the plough 4 through wet soil backflow otch 10, accomplishes the depthkeeping of fertilizer and buries, and form V-arrangement kind ditch, and seed falls into through grain conductor 8 on the kind bed of formation, carries out the sowing of the more shallow degree of depth of seed.
