Description

Rice transplanter

Technical field:

The utility model relates to a kind of rice transplanter.

Background technology:

Disclose " rice transplanter automatically " patent by inventor's invention on the Chinese patent communique on January 23rd, 2002, this patent remains in some shortcomings, mainly shows as follows:

One, only being connected by two crossbeams of support and seeding loading box is transverse in the seeding loading box height regulating tank location then, seeding loading box easily moves forward and backward and swings on described crossbeam like this, seeding loading box can not get the power of directly bestowing of support, support is too crooked again, the tractive force difficulty that acts on the support is in alignment, causes the whole rice transplanter difficulty of travelling.

Two, constraint mechanism design improper cause getting insert the track operation that mechanism can not be in accordance with regulations, getting plug in device can not be in the optimal site seedling taking of seedling, rice shoot can not stand on earth after entering earth, get and insert that device also might pull up rice shoot or contact, have a strong impact on the quality of institute's rice transplanting with seedling that the front has been inserted earth.

Three, getting the external splint of plugging in device designs improper, the external splint head flushes with external splint, stay cord is connected when causing seedling taking with inside and outside clamping plate, get and plug in device stand under load seedling box plate and get the restriction of inserting the outer seedling of device outer panel, the seedling groove door difficulty that two external splint capitiforms become is opened, and seedling can't enter the seedling groove, the stay cord difficulty is successively opened inside and outside clamping plate during rice transplanting, the seedling groove door that two external splint capitiforms become can not be opened fully, is obstructed when causing seedling to be extruded by earth, makes rice transplanting be difficult to carry out smoothly.

Four, minor axis and rocking arm can not be corresponding with dilatory head drive shift position for fixedlying connected in the transmission mechanism, cause rice transplanting inhomogeneous.

The utility model content:

The purpose of this utility model is above-mentioned deficiency is improved, and provides a kind of rice transplanting effective rice transplanter.

The technical solution of the utility model: the utility model comprises dilatory head, support, seeding loading box, seedling separating device, get and insert mechanism, transmission mechanism, lifter, wherein gets to insert mechanism and have shaking the control plate, being installed in the rotating shaft and direction is controlled opposite a plurality of of plate and got plug in device with shaking of a rotating shaft, rotating shaft two ends; The crossbeam of described support crosses seeding loading box, and the front end frame of support is connected with dilatory head, and the rear end frame lands by two trailing wheels; Transmission mechanism one end power taking is held in addition by the connecting rod drive in dilatory head and is got slotting mechanism, and it is characterized in that: the front end frame and the rear end frame of described support all have the slip joint that can slide up and down, and this slip joint is fixedlyed connected with the seeding loading box bottom; The bottom, two sides of described seeding loading box is provided with and is used for described connecting rod and the described spacing position-limited rack of control plate that shakes; Described getting plugged in device and comprised a pair of inner splint, a pair of external splint, a pair of external splint head, a pair of trying to stop people from fighting each other, two inner splints are at regular intervals, this spacing forms the seedling groove, two external splint heads are fixed in the external splint top respectively symmetrically, its underpart is as the switch door of seedling groove, its top exceeds the top margin of external splint and forms horn mouth, described external splint becomes the shape basically identical of " L " shape and inner splint, and being close to the inner splint outside installs, try to stop people from fighting each other and be installed in the inner splint outside and overlapping external splint, respectively get between plug in device external splint and be connected with stay cord, this stay cord is connected with seedling separating device; Described transmission mechanism comprises a minor axis, a rocking arm, a connecting rod, and wherein minor axis one end has regulating tooth, and rocking arm has a corresponding tooth cover, and an end and the connecting rod of rocking arm are rotatably connected, and the other end is connected with the regulating tooth of described minor axis by its tooth cover.

Good effect of the present utility model:

1, because support of the present utility model has increased the slip section header at front end frame and rear end frame, this section header is affixed with the seeding loading box bottom again, not only can prevent to move and swing before and after seeding loading box is on the support crossbeam, seeding loading box and support are combined together, and make the tractive force that acts on the support in alignment as far as possible, be convenient to rice transplanter and travel.

2, because seeding loading box two side bottoms have increased position-limited rack, connecting rod and remote control rod are all moved in limited range, reached to regulate to get the speed of service of plugging in device and prevent to get and inserted the seedling contacted purpose that device and front have been inserted earth, guaranteed to get and inserted the regulation position seedling taking of device, made seedling can stand on earth reposefully at seedling.

3, because external splint head top exceeds the top margin of external splint, the shape of external splint and the shape of inner splint be basically identical also, and stay cord only is connected on the external splint, make and get when plugging in the device seedling taking, it is that seedling groove Men Yi opens that the external splint head is easily opened, seedling can enter the seedling groove that forms between two inner splints unimpededly, when rice transplanting, stay cord can draw external splint earlier, the seedling groove door that the external splint capitiform is become is opened fully, by trying to stop people from fighting each other inner splint is opened then, the control that seedling is no longer got plug in device is plugged in device and is inserted in the earth reliably and extruded to get by earth.

4, owing to the setting angle of rocking arm in the transmission mechanism and minor axis can be regulated, it can have optimum Match with the gear that advances of dilatory head, thereby can make seedling evenly insert earth.

The problem that comprehensive above-mentioned advantage, the utility model have solved that former rice transplanter exists is difficult to walk and sails and can't normal operation.
