Abstract
The utility model discloses a travelling gearbox for a rice transplanter, which comprises a box, a first shaft, a second shaft, an added shaft, a third shaft and an output shaft supplying power to seedling transplantation, wherein an intermediate gear and a short intermediate gear shaft which are assembled through a bearing are arranged on the box, and the short intermediate gear shaft is positioned at the center of the intermediate gear. The travelling gearbox has the advantages that: since the reverse intermediate gear is mounted, the travelling gearbox is added with a backward rotation direction, so that a rice transplanter with the improved gearbox can back up, does not transplant seedlings during turning and can return to the original place to transplant seedlings again after turning, consequently, large replanting areas cannot exist, and the problem of seedling-transplanting dead angles is prevented.
Description
Technical field
The utility model relates to a kind of gearbox, and specifically a kind of rice transplanter speed change walking case belongs to the rice transplanter apparatus field.
Background technology
Rice transplanter is with the planting machinery of rice seedling field planting in the paddy field, and function is to improve the work efficiency of rice transplanting and plant quality, realizes rational close planting, helps the mechanization of subsequent job.At present, rice transplanter can only travel forward, and can not drive in the wrong direction, and is when the angle, field, as shown in Figure 6 in rice transplanting, and rice transplanter can only orthodrome turning rice transplanting, and making that corner's circular arc forms the dead angle outward can't rice transplanting.
The utility model content
In order to address the above problem; The utility model has designed a kind of rice transplanter speed change walking case; This speed change walking case can make rice transplanter drive in the wrong direction, and can only travel forward, can not drive in the wrong direction, make corner's circular arc to form the problem that the dead angle can't rice transplanting outward thereby solved present rice transplanter.
The technical scheme of the utility model is:
A kind of rice transplanter speed change walking case comprises: casing, final drive shaft be I axle, counter drive shaft be the II axle, increase axle, the running gear axle of carrier pulley is the III axle, and for rice transplanting the output shaft of power is provided;
On the I axle through bearing assembling can be free around the rotation of mounting teeth wheel shaft and can not axially movable I axle three bevel gears and I axle duplicate gear;
Through spline assembling on the I axle can the free I axle speed retaining gear that moves and rotate with the axis along the mounting teeth wheel shaft;
On the II axle by spline and shoulder fixing with the rotation of mounting teeth wheel shaft but the II axle duplicate gear that can not move along axle;
Increase on the axle through the spline assembling can the free increase axle duplicate gear that moves and rotate with the axis along the mounting teeth wheel shaft;
Increasing on the axle by fixing the rotating but the increase shaft gear that can not move along axle of spline and shoulder with the mounting teeth wheel shaft;
On the III axle through bearing assembling can be free around the rotation of mounting teeth wheel shaft but can not axially movable III axle walking mesomerism gear;
Can be free moving and the tooth embedding that rotates with the axis separates wheel on output shaft through spline assembling along the mounting teeth wheel shaft;
On output shaft through bearing assembling can axial restraint move and can rotate freely band tooth embedding and with I axle three bevel gear meshed bevel gears;
On casing, be provided with mesomerism gear and idle wheel minor axis through the bearing assembling, described idle wheel minor axis is positioned at the center of mesomerism gear.
The directed rotation of engine drives I axle successively through I axle speed retaining gear, I axle duplicate gear, III axle walking mesomerism gear, drives rice transplanter walking fast forward, and the rice transplanting part is not worked.
The directed rotation of engine drives I axle, successively through I axle speed retaining gear, II axle duplicate gear, I axle three bevel gears, then through dividing two-way: leading up to output shaft bevel gear, the embedding of output shaft tooth separates wheel, output shaft, drives rice transplanter and carries out transplanting work; Another road through the output shaft bevel gear, increase shaft gear, increase axle, increase an axle duplicate gear, I axle duplicate gear, III axle walking mesomerism gear, drive rice transplanter and walk forward by spacing in the rows, cooperate transplanting work partly by the spacing in the rows rice transplanting.
The directed rotation of engine drives I axle; Successively through I axle speed retaining gear, II axle duplicate gear, I axle three bevel gears, increase shaft gear, increase axle, increase an axle duplicate gear, reverse mesomerism gear, I axle duplicate gear, III axle walking mesomerism gear, drive rice transplanter walking backward at a slow speed.Because separating wheel, the embedding of output shaft tooth is in released state, the idle running of output shaft bevel gear, and the rice transplanting part is not worked.
The advantage of the utility model is: thus through being installed, reverse mesomerism gear increased its direction of rotation backward; The rice transplanter that improves behind the gearbox can be retreated; Not rice transplanting when turning; Return original place rice transplanting again after the turning, so just not having very big benefit plants the district, has avoided rice transplanting dead angle problem.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
