Operation principle
(1) overall work principle
Tractor traction apparatus is connected with the hanging device of shallow raw groove cultivating and growing machine, drives shallow raw groove cultivating and growing machine to advance forward；The hydraulic output device of tractor is connected with the hydraulic means of shallow raw groove cultivating and growing machine, in tractor traveling process, tractor hydraulic drives hydraulic motor work, hydraulic motor drives screw turns by shaft coupling, under leading screw with lead screw guide rails combined effect, rotation limit, spiral plough limit moves downward, thus completing ditching operation；In trench digging process, motor power output shaft is connected with deceleration device, and motor speed is slowed down by deceleration device, then passes to separation brush through crank and rocker mechanism, separate brush to move reciprocatingly on track under the drive of crank and rocker mechanism, thus the gap increased between shallow raw groove；While separating dataller's work, accumulator provides power for fan, and shallow raw groove is carried out air blast by fan, thus being separated by each shallow raw groove；When ditcher mechanism holds planting furrow successfully, after the shallow raw groove of its disengagement, mechanical hand captures a shallow raw groove and moves to deep bead place, puts it into planting furrow；Compaction apparatus is under tractor hydraulic drives, by shallow raw groove compacting in planting furrow.
Requiring during the work of this special-purpose machinery to place shallow raw groove with shallow raw groove storage bin, shallow raw groove upwards lies on lifter plate.Often pile up shallow raw groove when being finished, need to manually increase.
(2) ditcher mechanism operation principle
When tractor-drawn planting machine is advanced forward, tractor hydraulic output device provides power for hydraulic motor, and hydraulic motor drives leading screw and spiral plough to rotate by shaft coupling, owing to lead screw guide rails is fixing, leading screw can move downward on rotation limit, limit, along with the traveling of tractor, completes trench digging.After having ditched, hydraulic motor reverses, and leading screw returns to elemental height.
(3) shallow raw groove mechanism operation principle is stored
Shallow raw groove storage bin is slightly larger in dimension than shallow raw groove size, and storage bin biside plate is open, and when shallow raw groove is arranged in storage bin, shallow raw groove longitudinal edge directly contacts along with separating to brush；Be arranged on pressure transducer on lifter plate sense shallow raw groove number, and signal is fed back to hydraulic lift, so as to raise along with the minimizing of shallow raw groove, to ensure highly there is shallow raw groove separating brush, often piles up shallow raw groove when being finished, need to manually increase.
(4) shallow raw groove separating mechanism operation principle
When shallow raw groove is arranged in storage bin, the longitudinal edge of shallow raw groove contacts along with separating to brush, separate brush to move reciprocatingly on track under the drive of crank and rocker mechanism, thus the gap increased between shallow raw groove, meanwhile, the shallow raw groove that gap is increased by fan carries out air blast, thus ensureing that shallow raw groove is separately separated out.
(5) grabbing device and system for compacting operation principle
When ditcher mechanism holds planting furrow successfully, after the shallow raw groove of its disengagement, mechanical hand captures a shallow raw groove and moves to deep bead place, and shallow raw groove falls in planting furrow under gravity naturally；Compaction apparatus is under tractor hydraulic drives, by shallow raw groove compacting in planting furrow.
Next just repeating the work process described in above 1～5, circulate with this, along with the advance of tractor, planting machine just continues to lay shallow raw groove.
Prior art is had following gain by the shallow raw groove cultivating and growing special-purpose machinery of Rhizoma Dioscoreae of the present invention:
The shallow raw groove cultivating and growing special-purpose machinery of this Rhizoma Dioscoreae is the special purpose machinery designed for the shallow raw problem of Rhizoma Dioscoreae, has that plantation efficiency is high, quality is good, working stability, does not hinder the features such as shallow raw groove.It addition, this machine is driven by tractor, make full use of tractor resource, reduce purchasing of farm implements, reduce the cost of mechanization production.This machine disposable can complete the operations such as trench digging, plantation, compacting, and function is comparatively complete, decreases manual labor.
The above technology of the shallow raw groove cultivating and growing special-purpose machinery of this Rhizoma Dioscoreae and advantage, solve the shallow raw groove cultivating and growing labor intensity problem taken a lot of work big, time-consuming of Rhizoma Dioscoreae, improve the Mechanization Level of the shallow agricultural climate condition for corn of Rhizoma Dioscoreae, the research and development for the shallow raw groove cultivating and growing special-purpose machinery of Rhizoma Dioscoreae provides solution.
