The seedling pushing device of hand-held transplanter
Technical field
The present invention relates to a kind of hand-held transplanter, particularly to a kind of seedling pushing device of hand-held transplanter.
Background technology
During existing hand-held transplanter carries out rice transplanting, first pass through the appropriate band seedling soil block of seedling pin crawl and move to
Low spot, then pass through seedling pushing device action, band seedling soil block high speed is pushed into field, completes rice transplanting.Because existing seedling pushing device is by pushing away
Seedling head and the all-in-one-piece L-type structure that is fixedly connected of pawling, after high speed pushes away and in the motion of seedling, band seedling soil block is inserted in ground, push away
In seedling device back off procedure, pawling and water between, pawling under the active force being formed and the top of rice shoot between, can be by band seedling soil block
Extract upwards from soil, rice shoot adhesive force over the ground low it may appear that floating seedling phenomenon, when serious, it is also possible to make under wind action
The displacement that whole strain is upside down in muddy water or plants strain, causes rice transplanting uneven.
Content of the invention
The technical problem to be solved is for the deficiencies in the prior art, provides a kind of reasonable in design, user
The seedling pushing device of hand-held transplanter just.
The technical problem to be solved is to be realized by following technical scheme, and the present invention is a kind of hand steered
The seedling pushing device of formula rice transplanter, is characterized in, including pushing sprout pole and pawling, symmetrical being provided with the lower end of pushing sprout pole is arranged down
Two pieces of otic placodes, are provided between otic placode and place the space pawled, the described rear portion pawled is vertically arranged by the axis with pushing sprout pole
Rotary shaft connect with two pieces of otic placodes, be provided with retainer in the rear end pawled, the rear end of the top of pushing sprout pole and retainer it
Between be provided with and drive the extension spring of reset of pawling.
The technical problem to be solved can also be realized further by following technical scheme, pushes away described
The lower surface of pawl is provided with flexible material layer.
The technical problem to be solved can also be realized further by following technical scheme, described pawls
Push away finger portion by left and right two to form.
The technical problem to be solved can also be realized further by following technical scheme, described pushes away finger
The top in portion is in be horizontally disposed with, and push away finger portion is the lower oblique line setting towards the downward-sloping setting of pull bar below.
Compared with prior art, the present invention, during high speed rice transplanting, by pawling and progressively contacting with seedling soil block, is led to
Cross the buffering in structure, in conjunction with the effect of soft material layer, seedling pushing action becomes very soft, it is to avoid hard contact is to rice shoot
Damage, and after the completion of rice transplanting, pawl in the presence of water, for being downwardly inclined setting, reduce water to the absorption affinity pawled, keep away
Exempt to be carried over the rice shoot being plugged in the back off procedure pawled, improved rice transplanting quality, it is reasonable in design, structure is simple, behaviour
Facilitate.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Referring to the drawings, further describe the concrete technical scheme of the present invention, enter in order to those skilled in the art
One step ground understands the present invention, and does not constitute the restriction to its right.
With reference to Fig. 1, a kind of seedling pushing device of hand-held transplanter, include pushing sprout pole 1 and pawl 4, in the lower end pair of pushing sprout pole 1
Claim is provided with the two pieces of otic placodes 2 arranging down, be provided between otic placode 2 place pawl 4 space, described 4 rear portion of pawling is passed through
Rotary shaft 6 vertically disposed with the axis of pushing sprout pole 1 is connected with two pieces of otic placodes 2, and pawling, 4 rear end is provided with retainer 7, is pushing away
It is provided with the extension spring 8 driving reset of pawling between the rear end of the top of seedling bar 1 and retainer 7.
It is provided with flexible material layer in described 4 lower surface of pawling, when pushing away seedling, under the elastic reaction of flexible material layer,
Action becomes soft, significantly reduces the degree of injury to rice shoot of pawling, and improves rice transplanting quality.
Described pawling 4 pushes away finger portion by left and right two and forms, and the described top 3 pushing away finger portion is in be horizontally disposed with, and pushes away under finger portion
Side 5 is the lower oblique line setting towards the downward-sloping setting of pull bar 1, when pushing away seedling, pawl 4 be downwardly inclined setting below, then pawl
The following of rear portion first contacts rice shoot, and contact area is big, just rice shoot will not be damaged, during progressively pushing, pawl point is
Contact soil block afterwards, it is to avoid pawl point damages rice shoot with contacting first of seedling soil block, rice shoot is provided and preferably protects.
Seedling pin captures fritter band seedling soil block, moves to minimum point, then seedling pushing device action, pushing sprout pole 1 moves downward, because pushing away
Following the 5 of pawl 4 be lower inclined plane, the root pawled first contact band seedling soil block, continue to push, pawl 4 bottom from root to head
Come into contact with band seedling soil block, meanwhile, pawl 4 under the effect of the support force with seedling soil block, 4 heads of pawling gradually move upwards, pass
Dynamic seat 7 moves down, and whole process is a relatively soft process, has obtained good protection to rice shoot, after rice transplanting terminates, has pushed away
Pawl 4 is separated with band seedling soil block, pawls 4 under the pulling force effect of extension spring 8,4 rear ends of pawling are lifted, 4 front ends of pawling push, and are in
Towards outer incline, water diminishes to 4 resistance of pawling, and meanwhile, will pawl 4 when extracting out below rice shoot, rice shoot will not be taken out of it is ensured that
Rice transplanting quality.
