Description

Pull and push type man power rice transplanter

A kind of small farm manual rice transplanter tool.

The available man-power rice transplanter, the operating path of manipulator and corresponding operational motion have repetition " it " word broken line type, or the loop formula, move all too complicated, inefficiency, structure is complexity also, does not move case apparatus again mostly, the effect of separating seedlings or planting is not good enough.So difficulty is applied, Shang Weijian has a kind of manual rice transplanter easy and simple to handle, simple in structure, high efficiency to use for wide farmers.

The utility model purpose provides a kind ofly operates with push-pull fashion, the rice transplanting manipulator is done vertically to rise and fall up and down substantially, move easy, the rice transplanter that efficient is high, ingenious design seedling box mover when realizing this main goal of the invention, finish the seedling case and move in same operating process, complete machine structure is simple.

It is as follows to sketch its scheme:

Rice transplanter contains organic frame, end planker 2, seedling case 9, manipulator 1, action bars 10 and transmission mechanism, it is characterized in that the rocking bar swinging around horizontal dead axle be an action bars, each fixed connection one rocking arm 7 of operation rocking bar rotating shaft 8 two ends; rocking arm external part and manipulator crossbeam swing shaft 27 do to promote this along the connection of slippage up and down of vertical guide groove on the frame; crossbeam and its swing shaft do to allow the connection of the spacing beat of crossbeam; the rice transplanting manipulator is installed; dispose crossbeam beat and manipulator opening and closing controlling organization; control manipulator by the numbers thereon synchronously on the crossbeam; pendulum carry in lower dead center is finished respectively nearby; clamp together the folder seedling and dehisce to take off seedling, the action that outer pendulum is given up the throne.

For preventing rice shoot vacancy or seedling strain inequality to occur after seedling taking place of seedling case is because of a preceding seedling taking, except that seedling case at the bottom of adopting arc and be provided with and press seedling spring 11 to promote also to be provided with seedling box mover rice shoots fill a vacancy, make the seedling case can do back and forth progressive moving.The leading edge place has vacant position at the bottom of the seedling case, and a seedling holding plate 12 is undertaken in the vacancy below, and the breach that passes through for the manipulator jaw is arranged on the seedling holding plate, hold to minimizing moves the case resistance, seedling case bottom is bearing on the frame with rolling member 13, and seedling case and frame are done vertically, vertical location, the laterally connection of slip.Adopt two-way ratchet rackwork to move case, tooth bar 14 is fixed on the seedling case rear surface, it can be energy beidirectional rectangle tooth bar, or two unidirectional zigzag tooth bars are oppositely also adorned, the tooth bar two ends are provided with two-way ratchet commutation collision block or high tooth 19, two-way ratchet 15 is with the hinged pawl base 16 that is linked in of symmetrical centre, and do switchable two-way location with elastic force steel ball 21 in the ratchet back, pawl base is linked in fixing horizontal concrete chute 17 neutralization with slide block (or pulley) 20 and is bearing on the chute, and pawl base also connects with the cam 18 that is fixed in the rocking bar rotating shaft of its slippage of control.The push-and-pull rocking bar, under the cam effect, the pawl base band is done laterally toward polyslip with ratchet, thereby promote ratchet bar together with tooth pitch of seedling case slippage, operate rocking bar again, the removable again tooth pitch of seedling case, when seedling case (or to the right) progressive traversing case position left, collision block on the tooth bar or high tooth 19 make the ratchet commutation, and next operation, seedling case begin oppositely progressive traversing.

The utility model is with simple push-pull fashion operation rocking bar, promote that the rice transplanting manipulator is finished carry, folder seedling, inserted down, loose seedling, give up the throne, transplanting work circulation overall process such as rise and corresponding seedling case move, move terse, efficient height and simple in structure.

Accompanying drawing has provided an example concrete structure of the present utility model.Fig. 1 complete machine structure front perspective view, Fig. 2 complete machine structure rear view, Fig. 3, Fig. 4, two-way ratchet tooth bar (zigzag is oppositely also adorned) moves case apparatus, Fig. 5, manipulator, crossbeam and connecting structure thereof, Fig. 6, manipulator crossbeam beat controlling organization.

Be described further below in conjunction with accompanying drawing.

The machine underframe has left and right curb girder 3, the curb girder guide groove column 4 of having gone forward, after rocking bar rotating shaft mounting 6 is arranged, the rocking bar 10 nearly shapes of erectting connect firmly at rotating shaft 8 middle parts, two rocking arms 7 become nearly 90 ° of angles of cut to connect firmly in rotating shaft two ends and rotating shaft with rocking bar; the rocking arm external part is with the swing shaft 27 of notch clamping manipulator crossbeam 5, and swing shaft 27 can slippage in the column guide groove.The manipulator that one row n individual (diagram n=6) is made up of two intermediate plates is spacing with the seedling planting row pitch, being that hinged point is parallel with the upper end is installed on the crossbeam, manipulator lower end jaw bends inwards, the middle part hinge is associated with the opening and closing control strip 22 that connects with central pressure-raising bar 23, the pressure-raising bar is positioned at the manipulator symmetrical centre, pass crossbeam, with spring-loaded on crossbeam, the top abuts in pulley 24 on the inclined-plane of collision block 25 of push rod 26, the pressure-raising pole length is adjustable, in order to adjust the manipulator opening width, push rod 26 runs through crossbeam balance staff 27, outer end head installing rolling member 30, and when keeping the push rod resting state with spring 31 the head rolling member stretch in outward on the guide groove column diapire face on give up the throne in the notch, this diapire face is corresponding to last, the lower dead center place is on having, following two notches 29 of giving up the throne, and corresponding slope is arranged; Folder is lined with location-plate 28 between crossbeam and its balance staff, and location-plate connects with the balance staff relative fixed, and crossbeam is realized relative connection of locating beat with location-plate with elastic force steel ball socket arrangement 32; The notch place of giving up the throne under the guide groove column is provided with crossbeam rotation collision block 34 tops the crossbeam fork part 33 that resets is housed, and this fork spare is pushed on the yoke when rocking arm gos up and puts, and drives another yoke bottom and forces the crossbeam beat to reset.

Frame rear end and end planker are with axle hinge connection, and front end is made the connection of adjustable lifting, in order to the suitable adjusting rice transplanting depth.The guide groove column is also made connecting of front and back adjusting with frame, in order to regulate the degree of depth that the manipulator carry is eaten seedling, adds the adjusting of manipulator opening and closing degree, can regulate seedling strain thickness.
