Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention is such that a single rail is laid between each row of tea tree ridges planted in a row, and the laying rails between the left and right ridges that sandwich the tea tree ridge run as a pair of tracks. The present invention relates to an orbital carriage of an orbital type tea leaf plucking machine capable of performing various operations such as plucking, pruning and controlling tea leaves over the entire surface of a tea tree ridge.

[0002]

2. Description of the Related Art An orbital type tea leaf plucking machine as described above is conventionally known, and is disclosed in, for example, JP-A-1-174430.
The prior art described in Japanese Patent Laid-Open No. 4-91716 and the like is known, and the applicant has also proposed the prior art described in Japanese Patent Laid-Open No. 4-320613.

This type of device uses a rail laid between the left and right ridges that sandwich the tea tree ridge as a pair of tracks, and has a gate-shaped structure that straddles the tea tree ridge between left and right track carriages that move along the rails. A frame is erected, and a plucking device equipped with a mowing part and a bag receiving part over the entire surface of the tea tree ridge is vertically movably attached to the portal frame. When plucking the tea leaves, the track carriage is advanced with the cutting blade lowered to the plucking depth of the tea tree ridges, and the tea leaves are plucked by this forward movement while the plucked tea leaves are stored in the bag. Proceed,
When the plucking operation on the predetermined route is completed, the cutting blade is raised to a predetermined height and returned to the plucking start end at a high speed, the stored tea leaf bags are exchanged, and the next plucking operation is started.

[0004]

By the way, in the case of performing various operations (tea leaf picking, pruning, pest control, etc.) in a tea field using the above orbital type tea leaf plucking machine, in a tea field on a slope, There was such a problem.

In a tea field on a sloping land, as shown in FIG. 10, there may be a difference in height between the laying rails b and c between the left and right ridges that sandwich the tea tree ridge a. When traveling on rails b and c as a pair of tracks, the gate-shaped frame d installed between the left and right track carriages and the plucking device e supported between the left and right columns of the gate-shaped frame are When the hem heights h on both sides are made substantially the same, the picking device e traveling on the rails b and c is tilted greatly as shown by the two-dot chain line, and component force acts in the tilting direction due to gravity. The specific gravity applied to the valley side of the slope increases. In this case, in the track carriage of the conventional track type tea leaf plucking machine, the support portions of the wheels f and g traveling on the rails b and c are
Since the wheels f and g are fixedly attached to the respective bogie frames, the wheels f and g are in a slanted state as indicated by imaginary lines with respect to the rails b and c, and the rolling wheels f and g
However, there is a problem that the phenomenon of slipping off the rails b and c and derailing is likely to occur.

Further, in the conventional case, the left and right track carriages running on the rails and the pillar portions of the gate-shaped frame installed between the left and right carriages are integrally formed, so that the plucking device described above is used. With respect to the inclination, as a means for correcting the inclination angle, it is unavoidable to adopt a means for extending the support pillar of the gate-shaped frame on the valley side, and in this method, the strength of the portal frame occurs due to the extension of the support pillar, and the stability is improved. However, there is a problem in that the traveling performance is adversely affected by the loss of the weight, and in addition, a special telescopic cylinder or the like is required to extend the strut portion of the frame, resulting in a large and complicated structure.

The present invention has been proposed in view of the above problems, and in a tea garden on a sloping ground, even if there is a difference in height between a pair of rails, the phenomenon that the rolling wheels of the track truck derail from the rails is generated. It is an object of the present invention to provide a track carriage for a track type tea leaf plucking machine, which can easily correct the inclination angle of the plucking device and improve traveling performance.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides, in a conventionally proposed orbit type tea leaf plucking machine, support for each wheel of an idle front wheel and a drive rear wheel traveling on a rail. The frame is configured to be attached to the bogie frame so that it can be tilted and deviated to the left and right of the rail axis with respect to the rail, and on a sloping ground where there is a height difference between the left and right track bogies, the wheel support frame is tilted and deviated to the higher side in the inclination direction. It is characterized in that the floating front wheel and the driving rear wheel can be changed in position on the vertical line of the rail axis by being fixed by being positioned.

Further, according to the present invention, a connecting pillar for connecting the lower parts of the pillars of the gate-shaped frame to the respective carriage frames of the left and right track carriages in an extendable manner is erected, and the gates are installed between the left and right track carriages between the carriages. Another feature is that each of the left and right columns of the shaped frame is independently adjustable in height.

[0010]

According to the above-mentioned structure, when the orbital type tea leaf plucking machine is used in a tea plant on a sloping ground, there is a difference in height between a pair of rails laid between the ridges and the gate frame and plucking that are installed between the bogies. Even if the device is tilted, the idle front wheels and the driven rear wheels of the track carriage traveling on the rails can be positioned on the vertical line of the rail axis, so that the phenomenon that the rolling wheels fall off the rails during traveling does not occur.

Since the heights of the left and right columns of the gate-shaped frame, which are installed between the carts, can be independently adjusted for the left and right track carriages, the heights of the pillars can be independently adjusted. The plucking device equipped with the receiving part moves up and down integrally, and the height of the plucking device can be easily adjusted with one touch, and the tilt angle of the plucking device can also be easily corrected by extending the prop on only the low side. It is also possible to improve the deterioration of the driving performance caused by the inclination.
