Description

Transplanter

Technical field

The utility model belongs to agricultural machinery technological field, specifically, and particularly a kind of rice seedling transplanter.

Background technology

At present, country greatly develops agricultural machinery, and transplanter miscellaneous emerges in an endless stream.Generally speaking, popular transplanter is broadly divided into full-automatic, semi-automatic and manual three kinds of forms on the present market.But all in all, the difference between them is mainly on getting seedling, falling the seedling mode.In detail, the process of taking out seedling from seedling-cultivating tray can be referred to as to get the seedling process, and the process that seedling is placed in the earthenware can be referred to as the seedling process.And all transplanters plant seedling in the process of burying going into earthenware, are to be finished by machinery without exception.We get seedling, the seedling process that falls all is transplanters of finishing automatically, can be referred to as Automatic Transplanter as can be seen thus, and get seedling, the seedling process that falls has a process to be finished by machinery, then semi-automatic transplanter can be referred to as, and, then manual transplanter can be referred to as all by manually finishing.Existing transplanter all has its shortcoming of can not ignore, and its concrete manifestation is as follows:

1, the Automatic Transplanter cost is too high.Because it is complicated to get the seedling action, use the action of mechanical system simulation staff to need complicated circuit to be controlled, or need special seedling-cultivating tray to cooperate with it, and seedling is got in realization and the mechanism of the seedling that falls is complicated, has increased production cost and maintenance cost greatly.

2, to get the seedling seedling efficient that falls low for manual or semi-automatic transplanter.With above-mentioned viewpoint, the sizable in fact part of product of calling oneself at present semi-automatic transplanter on the market can only be called as manual transplanter, and the seedling seedling mode that falls of getting of these manual transplanters is: operating personnel take out seedling with hand and directly lose in the earthenware from seedling-cultivating tray.Operating personnel need be wholeheartedly dual-purpose like this, needs the position of seedling in seedling-cultivating tray, location on the one hand, so that take out seedling smoothly, needs the location to go into the earthenware position on the other hand, so that seedling falls into earthenware smoothly.Operation dependency to operating personnel is big like this, and labor intensity of operating staff is bigger, is prone to fatigue, has increased the probability of makeing mistakes.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of transplanter of the seedling that can fall automatically.

The technical solution of the utility model is as follows: a kind of transplanter, comprise frame and the seedling box that falls, be supported with major axis and minor axis by bearing on its mid frame, suit major axis sprocket wheel on major axis, this major axis sprocket wheel is connected with minor axis sprocket wheel on the minor axis by sending the seedling chain, its key is: be fixed with substrate described sending on the seedling chain, the upper end of this substrate is rotatably mounted with ratchet, and the column that is equipped with the restriction ratchet to rotate; The spacers that matches with described ratchet all is equipped with cross slide way in the front end of the seedling rail bracket that falls in the front and back end of the seedling rail bracket that falls, and each cross slide way matches with the guide roller of the seedling box bottom that falls; At the front end of the described seedling box that falls and fall and be connected with extension spring between the seedling rail bracket, the bottom of the described seedling rail bracket that falls is provided with the longitudinally guiding wheel, and this longitudinally guiding wheel matches with longitudinal rail on the frame; Also be provided with the return bearing on the described frame, this return bearing stops spacing to the lower end of ratchet.

Adopt above technical scheme, the seedling box that falls is accepted the rice shoot that falls from transplanter seedling clipping machine structure, along with transplanter is advanced forward, sprocket wheel on the transplanter live axle is given major axis by chain-drive mechanism and gear with transmission of power, make the rotation of major axis and major axis sprocket wheel, the major axis sprocket wheel drives minor axis and the rotation of minor axis sprocket wheel by sending the seedling chain, send substrate on the seedling chain and turnover box with sending the seedling chain to move, when ratchet with sending the seedling chain movement when the pads placement, because ratchet is subjected to the restriction of column, can not freely rotate, the upper end of ratchet promotes pad, make the seedling rail bracket to move backward, move to the position of return bearing, be subjected to stopping of return bearing until ratchet together with the seedling box integral body that falls, ratchet turns an angle around its mounting points, make the upper end of ratchet avoid pad, this moment, the seedling rail bracket that falls was together with the seedling box integral body return forward that falls under the effect of extension spring.

For simplified structure, the convenient installation, and the flexibility and the reliability of the motion of raising ratchet, upper end at described substrate is vertically installed with turning cylinder, kink ratchet on this turning cylinder, and torsion spring also is installed on the turning cylinder, and an end of this torsion spring is connected with ratchet, and the other end of torsion spring is connected with substrate, described column is positioned at the below of turning cylinder, and matches with the bayonet socket at ratchet edge.

Be set with first gear in the upper end of described major axis, this first gear is meshed with second gear on first locating shaft, and be fixed with first sprocket wheel on second gear, described first sprocket wheel is connected with second sprocket wheel by chain, second sprocket wheel is installed on second locating shaft, and be fixed with the 3rd sprocket wheel on second sprocket wheel, described the 3rd sprocket wheel is connected with the 4th sprocket wheel by chain, the 4th sprocket wheel is installed on the 3rd locating shaft, and the promotion bearing all is installed on the 4th sprocket wheel and the 3rd sprocket wheel prejudicially, and this promotion bearing is arranged in the stopper slot of seedling box bottom one side.In the above structure, in the time of the major axis rotation, drive first gear movement, the rotation of first gear driven, second gear, make with coaxial mounted first sprocket wheel of second gear and drive the rotation of second sprocket wheel by chain, the 3rd sprocket wheel of installing with second sprocket coaxiality drives the 4th sprocket rotation by chain again, because the promotion bearing on the 4th and the 3rd sprocket wheel is eccentric the installation, promote bearing and drive the seedling box by stopper slot, move back and forth about making the seedling box with respect to the seedling rail bracket that falls and doing, accepting the rice shoot that the seedling clipping machine structure falls, and rice shoot is transported to the top of turnover box, after waiting that the seedling box is opened, rice shoot falls in the corresponding turnover box automatically.

Beneficial effect: the utility model will be got seedling, the seedling process that falls is separated, and the seedling process that falls realizes automatically, has realized many young plants that once fall, and has improved operating efficiency.Seedling-cultivating tray with 128 caves, 8 * 16 specifications is given an example, but once gripping 8 strains fall simultaneously, can comprehend after seedling falls, and directly begins the next one and gets the seedling action, and the seedling process that falls is carried out automatically synchronously, has reduced manipulation strength, has improved the seedling precision that falls.Get the seedling process leeway of selecting then is provided, the user can select suitable seedling picking mechanism according to self-condition, and transplanter is transformed into semi-automatic or full-automatic mode.Have simple in structure, assembling easily, cost is low, be easy to characteristics such as maintenance, transplanting efficiency height.
