Abstract
The invention provides a high-speed precision seeder, belonging to the technical field of seeders. According to the high-speed precision seeder provided by the invention, a seeding single frame is connected with a frame assembly, a seed box is arranged at the upper part of the frame assembly; a disk ditching device, a sliding knife ditching device, a soil covering device and a compacting and depth-limiting wheel are sequentially arranged on the seeding single frame from front to back; a seeding depth regulating rod is connected between connecting rods of the seeding single frame and the compacting and depth-limiting wheel, a seeding device and a seed guide pipe are fixed at the middle part of the seeding single frame, and a ditching device front pressure spring and a ditching device back pressure spring are respectively mounted at the front part and the back part of the sliding knife ditching device. The high-speed precision seeder provided by the invention has the beneficial effects of strong adaptability of the seeder to soil during high-speed seeding, smooth seed ditches, stable ditching depth and close contact between seeds and soil at the bottom of each ditch, and can significantly improve the transverse distribution and the seeding depth of the seeds in the ditches and greatly improve the seeding operation quality.
Description
Technical field
The present invention relates to a kind of high speed and precision sower, belong to technical field of seeders.
Background technology
Seeding machinery is one of tool of production the most basic in agricultural production, and most of high speed and precision seeding machineries adopt disk coulter or sliding cutter plough.Disk coulter can cut off undesirable root in soil, strong to soil suitability, but exist while sowing at a high speed, outputs kind of a ditch out-of-flatness, affects the problems such as the cross direction profiles of seed in ditch and sowing depth; Sliding cutter plough can be outputed smooth kind of ditch, make seed can with ditch ground soil close contact, absorb more germination moisture, but the problem such as ditching depth is unstable while having the high speed seeding operation.
Summary of the invention
The objective of the invention is the problem existed in order to solve above-mentioned prior art, disk coulter exists while sowing at a high speed and outputs kind of a ditch out-of-flatness, affects the cross direction profiles of seed in ditch and the problem of sowing depth; The unsettled problem of ditching depth when there is the high speed seeding operation in sliding cutter plough.And then provide a kind of high speed and precision sower.
The objective of the invention is to be achieved through the following technical solutions:
A kind of high speed and precision sower, comprise: support assembly, plant case, the planter frame, seeding unit and grain conductor, pressing spring after plough, the setting sowing depth bar, disk coulter, pressing spring before plough, sliding cutter plough, covering device and suppression gauge wheel, described planter frame is connected with support assembly, the kind case is arranged on the top of support assembly, disk coulter, sliding cutter plough, covering device and suppression gauge wheel are successively set on the planter frame from front to back, be connected with the setting sowing depth bar between the connecting rod of planter frame and suppression gauge wheel, seeding unit and grain conductor are fixed on the middle part of planter frame, the front and rear of sliding cutter plough is separately installed with before plough pressing spring after pressing spring and plough.
The invention has the beneficial effects as follows: when sowing at a high speed sower strong to soil suitability, plant that ditch is smooth, ditching depth stable, seed can with bottom of trench soil close contact, cross direction profiles and the sowing depth of seed in ditch is significantly improved, and the seeding operation quality is greatly improved.
The accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of high speed and precision sower of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail: the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed embodiment, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, a kind of high speed and precision sower that the present embodiment is related, comprise: support assembly 1, plant case 2, planter frame 3, seeding unit and grain conductor 4, after plough, pressing spring 5, setting sowing depth bar 6, disk coulter 7, pressing spring 8 before plough, sliding cutter plough 9, covering device 10 and suppression gauge wheel 11, described planter frame 3 is connected with support assembly 1, kind case 2 is arranged on the top of support assembly 1, disk coulter 7, sliding cutter plough 9, covering device 10 and suppression gauge wheel 11 are successively set on planter frame 3 from front to back, be connected with setting sowing depth bar 6 between the connecting rod of planter frame 3 and suppression gauge wheel 11, seeding unit and grain conductor 4 are fixed on the middle part of planter frame 3, the front and rear of sliding cutter plough 9 is separately installed with before plough pressing spring 5 after pressing spring 8 and plough.
The diameter of described suppression gauge wheel 11 is less than the diameter of disk coulter 7.
The outlet of described seeding unit and grain conductor 4 is arranged on the rear portion of sliding cutter plough 9.
During operation, tractor is drawn sower by the hanger bracket on support assembly 1.During sowing, at first disk coulter 7 outputs the kind ditch of sowing depth 3/4, then outputed the kind ditch of residue sowing depth 1/4 by sliding cutter plough 9, simultaneously the ditching depth of sliding cutter plough 9 by plough before after pressing spring 8 and plough pressing spring 5 carry out depth stop control, reduced the impact that the rear profiling of suppression gauge wheel 11 lags behind.Adopt disk coulter 7 and sliding cutter plough 9 combination and cooperation trench diggings, make sower reach strong to soil suitability, plant that ditch is smooth, ditching depth stable, seed can with bottom of trench soil close contact, operation quality is good, the purpose that efficiency is high.
The above; it is only preferably embodiment of the present invention; these embodiments all are based on the different implementations under general idea of the present invention; and protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
