Description
Technical field
The present invention relates to a kind of agricultural machinery, more particularly, to a kind of improvement of the pontoon hull structure to rice transplanter.
Background technology
In agricultural production, the depth of paddy field reclaimed water directly affects growth and the yield of rice, and the depth of water is excessively shallow, soil exposure
Easily raw weeds, the depth of water can cause very much rotten of rice shoot deeply in atmosphere, produce pest and disease damage.In order to suppress weed growth, rice is prevented
Base portion is improved yield, the mud bed in paddy field should be made smooth by insect pest.A kind of rice transplanter such as the A of Publication No. CN 106332582 floats
Ship, including kickboard, the kickboard middle part are vertically arranged with central sill, and kickboard front end two corners are curved to both sides transition, described
Kickboard front end upwarps, and the kickboard front underside is arc shiny surface, and the central sill lower surface protrudes from kickboard lower surface 30-
80mm.Although the technical scheme can cross control water depth, its is complicated, and drainability is weak, gathers around mud and pushes away that water is serious, the water of formation
Wave can wash upside down the rice shoot being plugged, and causing can not normal rice transplanting.A kind of and for example U of Publication No. CN 205378527 rice transplanter
The deck of boat, including：The bottom of the ship board for rice transplanter is provided with multiple tie ridgers；Characterized in that, opened up on the ship board for rice transplanter
There is fertilizer applying hole, the fertilizer applying hole is fixed in the fertilizer applying hole of the ship board for rice transplanter between two adjacent tie ridgers
Provided with conduit.The technical scheme is provided with tie ridger, can not pave mud bed, kind be implanted with the ridge of rice seedling due to being higher by the water surface and
Easy growth of weeds, the growth of rice shoot is influenceed, yield can not be improved.
The content of the invention
Present invention mainly solves complicated present in prior art, mud bed can not be paved, drainability is weak, it is impossible to holds
The technical problems such as seedling carrying base, there is provided it is a kind of simple in construction, mud bed can be paved, drain function is strong, can hold the rice transplanter of seedling carrying base
Pontoon.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：A kind of load-bearing of rice transplanter
Formula pontoon, including hull, it is characterised in that：Depression forms some rhones, each described draining to described underside of ship hull upwards
Groove is longitudinally disposed along described hull, and the depth of each described rhone is 4~6cm, and the width of each described rhone is
16~22cm, between adjacent described rhone between groove, the rear between each described groove is corresponding with two rice transplantings and grabbed, respectively
The overall width of rhone between described groove described in adjacent thereto one is 46~56cm, and described hull is provided with seedling platform
Installing mechanism., can be smooth by the mud bed in paddy field using this scheme, while rhone arranges the muddy water assembled in front of pontoon in time
Go out, avoid gathering around mud and push away water and form water wave and wash upside down the rice shoot planted, and seedling carrying base can be held.
Preferably, described hull is provided with shallow-layer fertilizer applying hole, the shallow-layer fertilizer applying hole is each described between described groove
Groove between be corresponding with shallow-layer fertilizer applying hole described in two, rear is described between each described shallow-layer fertilizer applying hole and groove where it

Subsoil application hole lower section, and the projection in the bottom of hull is covered in described subsoil application hole corresponding to its, each described
Bottom of the rear end of deep layer plough away from described hull distance it is identical with the length of hard long duct.Using this scheme,
Deep layer plough outputs dressing furrow in mud bed deep layer, and guiding fertilizer enters dressing furrow, fertilizer is smoothly reached subsoil application position,
Fertilizer loss is prevented, while avoids mud from blocking subsoil application hole and hard long duct.
Preferably, each described rhone is provided with some harrow nails, each described harrow nail is connected to described rhone
Upper bottom portion.A part of mud can be somewhat swelled in the mud bed that the rhone of pontoon passes through, the part mud may be exposed to
Weeds are produced in air, using this scheme, set harrow nail to split the mud of the protuberance in rhone, due to muddy
It is soft, can not be molded after segmentation and it is scattered collapse, spread the mud of the protuberance out and pave submerged in water, prevent weeds propagation and widespread.
Preferably, each described harrow nail is distributed in the afterbody comb shape of described rhone, each described harrow nail is in downward
The arcuate structure of bending, the bottom of itself and described hull is in 15 °~45° angle, and the nail tip of each described harrow nail is pointed to described
The rear of hull and alignd with the bottom of described hull.Using this scheme, the mud of protuberance can be made to cut more tiny, made
Mud, which easily collapses, to be shakeout, and avoids harrow nail from collapsing the weeds in mud, influences harrow nail segmentation mud.
The beneficial effect that the present invention is brought is to simplify the structure of pontoon, smooth mud bed, improves the draining energy of pontoon
Power, fertilization effect is good, holds the functions such as seedling carrying base.
Therefore, the present invention have it is simple in construction, can smooth paddy field mud bed, drain function is strong, and fertilization effect is good, can carry
