The seedling pushing device of hand-held transplanter
Technical field
The present invention relates to a kind of hand-held transplanter, more particularly to a kind of seedling pushing device of hand-held transplanter.
Background technology
During existing hand-held transplanter carries out rice transplanting, first passes through seedling needle and capture suitable band seedling soil block and move to most
Low spot, then acted by seedling pushing device, it will be pushed into field with seedling soil block high speed, and complete rice transplanting.Since existing seedling pushing device is by pushing away
Seedling head and the integral L-type structure that is fixedly connected of pawling will push away after being inserted in ground with seedling soil block in the movement for pushing away seedling at a high speed
It, can will be with seedling soil block in the case where pawling between water, pawling the active force that is formed between the top of rice shoot in seedling device back off procedure
It is extracted upwards from soil, the adhesive force of rice shoot over the ground is low, it may appear that floating seedling phenomenon, when serious, under wind action, it is also possible to make
Whole strain is upside down in muddy water or the displacement of kind strain, causes rice transplanting uneven.
Invention content
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of reasonable design, user
Just the seedling pushing device of hand-held transplanter.
The technical problem to be solved by the present invention is to what is realized by technical solution below, the present invention is a kind of hand steered
The seedling pushing device of formula rice transplanter, its main feature is that, including pushing sprout pole and pawl, is symmetrically equipped in the lower end of pushing sprout pole and is arranged downward
Two pieces of otic placodes are equipped with the gap placed and pawled between otic placode, and the rear portion pawled is vertically arranged by the axis with pushing sprout pole
Rotation axis connect with two pieces of otic placodes, be equipped with retainer in the rear end pawled, the top of pushing sprout pole and the rear end of retainer it
Between be equipped with driving and pawl the extension spring of reset.
The technical problems to be solved by the invention can also be further realized by technical solution below, be pushed away described
The lower surface of pawl is equipped with flexible material layer.
The technical problems to be solved by the invention can also be further realized by technical solution below, described to pawl
By left and right, two push away finger portion and form.
The technical problems to be solved by the invention can also be further realized by technical solution below, described to push away finger
In being horizontally disposed with, the following lower oblique line to tilt down setting towards push-pull rod for pushing away finger portion is arranged for the top in portion.
Compared with prior art, the present invention, by pawling and gradually contacting with seedling soil block, is led to during high speed rice transplanting
The buffering in structure is crossed, in conjunction with the effect of soft material layer, seedling pushing action becomes very soft, avoids hard contact to rice shoot
Damage, and after the completion of rice transplanting, pawl under the action of water, to be downwardly inclined setting, reduce water to the adsorption capacity pawled, keep away
The rice shoot that will be plugged is exempted to be carried in the back off procedure pawled, has improved rice transplanting quality, reasonable design is simple in structure, behaviour
Facilitate.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
Referring to the drawings, further describe the specific technical solution of the present invention, in order to those skilled in the art into
One step the present invention is understood, without constituting the limitation to its right.
Referring to Fig.1, a kind of seedling pushing device of hand-held transplanter, including pushing sprout pole 1 and pawl 4, in the lower end pair of pushing sprout pole 1
What is claimed is equipped with two pieces of otic placodes 2 being arranged downward, be equipped between otic placode 2 placement pawl 4 gap, 4 rear portion of pawling passes through
Connect with two pieces of otic placodes 2 with the vertically disposed rotation axis of the axis of pushing sprout pole 16, pawling, 4 rear end is equipped with retainer 7, is pushing away
The extension spring 8 for driving reset of pawling is equipped between the top and the rear end of retainer 7 of seedling bar 1.
It is described pawl 4 lower surface be equipped with flexible material layer, when pushing away seedling, under the elastic reaction of flexible material layer,
Action becomes soft, significantly reduces the degree of injury pawled to rice shoot, improves rice transplanting quality.
It is described pawl 4 by left and right two push away finger portion and form, the top 3 for pushing away finger portion pushes away under finger portion in horizontally disposed
Side 5 is the lower oblique line setting that setting is tilted down towards push-pull rod 1, and when pushing away seedling, 4 following of pawling is downwardly inclined setting, then pawls
The following of rear portion first contacts rice shoot, and contact area is big, will not just be damaged to rice shoot, and during gradually pushing, pawl point is most
After contact soil block, avoid pawl point and with the contact first of seedling soil block damage rice shoot, preferable protection is provided to rice shoot.
Seedling needle captures fritter band seedling soil block, moves to minimum point, then seedling pushing device acts, and pushing sprout pole 1 moves downward, because pushing away
Following the 5 of pawl 4 are lower inclined plane, and the root pawled first contact with seedling soil block, continues to push, pawl 4 lower part from root to head
Band seedling soil block is come into contact with, meanwhile, 4 are pawled under the support force effect with seedling soil block, and 4 heads of pawling gradually move upwards, and pass
Dynamic seat 7 moves downward, and whole process is a relatively soft process, has obtained good protection to rice shoot, after rice transplanting, has pushed away
Pawl 4 is detached with seedling soil block, pawls 4 under the pulling force effect of extension spring 8, and 4 rear ends of pawling are lifted, and 4 front ends pushing of pawling is in
Towards outer incline, water becomes smaller to 4 resistance of pawling, meanwhile, 4 will be pawled when being extracted out below rice shoot, rice shoot will not be taken out of, ensure
Rice transplanting quality.
