Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a walking-type rice transplanter for planting seedlings in a field.

(b) Prior art In a conventional walk-behind rice transplanter, a slide piece supports the middle part of a seedling platform that reciprocates in the horizontal direction so that it can slide freely, and the supports of this slide piece protrude inward from the left and right handles. A member was provided separately from the support plate, which stood upright on the plate and supported the marker operating lever in an up-and-down manner.

(c) Problems to be solved by the invention The known walk-behind rice transplanter requires separate support members for the slide piece and the marker operation lever, which increases the weight of the rear part of the machine and makes it difficult to operate. In addition, since the support point of the slide piece is inside the handle, if the seedling table is wide in a multi-row rice transplanter, the seedling table will move laterally and cause the cost to increase. There were problems such as increased vibrations in the parts that protruded greatly, deteriorating the stability of the aircraft, and increasing the amount of compression of the pine seedlings.

(d) Means for solving the problem The present invention has mounting seats protruding from the pair of left and right handles toward the outside on both right sides, and attaching the mounting seats to the middle part of the seedling stand. By supporting the slide piece strut that supports the upper part and the marker operation lever, the slide piece and marker are supported by a single mounting seat, reducing the weight and cost of the rear part of the fuselage. The above-mentioned problem was solved by supporting the seedling on the outside of the handle to suppress the vibration of the seedling stand.

(E) Function When performing planting work while moving the machine forward, the lower part of the seedling stand is guided by an apron as in the conventional one, and the middle part is guided by a guide rail on the lower surface by a slide rail.

During this time, even if the seedling stand reaches the end of lateral movement, the slide piece is supported via the support by the mounting seat protruding outside of the handle, so vibrations can be suppressed, and the slide By using a single mounting seat as the support member for the piece and the marker, the weight of the rear part of the fuselage can be reduced and the configuration can be simplified.

(f) Example An example of the present invention will be explained with reference to the drawings.
1 is similar to a conventional walk-behind rice transplanter, with an engine attached to the front and wheels supported via swing chain cases on both sides of the middle part. Float 2...
A planting rod 4 is attached to the front part of the planter transmission case 3 connected to the rear part of the planter, and a planting rod 4 is driven, and a seedling stand 5 which is tilted rearward and reciprocates in the lateral direction is driven at the upper part of the rear part.

Further, the seedling table 5 is supported at its lower part by an apron 6 so as to be able to move laterally, and the left and right sides of the guide rail 7a on the lower surface near the upper part are slidably supported by slide pieces 7, 7. A connecting rod 8 is fixed to the rear part of the planter transmission case 3.
Attachment seats 9, 9 are welded to the outer intermediate portions of the pair of left and right handles 8, 8 connected at a, respectively, and the upper parts of columns 10, 10 whose lower portions are screwed to the attachment seats 9, 9. The slide piece 7 is attached to the slide piece 7.

The bases of the markers 11, 11 are pivotally mounted to plates 13, 13 integral with the apron support frame 12, as shown in FIGS. 1 and 2, and the bases of the markers 11, 11 are The marker operating levers 15, 15 are pivotally supported on the mounting seats 9, 9 by fulcrum pins 14, 14, and are interlocked by rods 16, 16.

In FIG. 2, reference numeral 19 is an L-shaped lever whose bent portion is pivotally attached to the apron support frame 12.The base end is connected to the apron 6 with a bolt 20, and the tip is connected to the apron 6 with a rod 21. An adjustment lever 22 connected to and protruding from one lever 19 is inserted into a guide groove of a lever guide 22a, 23 is a clutch lever, and 24 is a planting depth adjustment lever.

In the above-mentioned walk-behind rice transplanter, when the machine is moved forward while driving the planting rods 4... and the seedling platform 5, the planting rods 4... scrape off the pine seedlings in the seedling platform 5 one by one. Plant it on the rice field.

At that time, the slide piece 7 is connected to the handle 8,
Supports 10, 1 are attached to mounting seats 9, 9 protruding from the outside of 8.
0, the seedling stand 5 is supported on its outer side, and vertical vibration can be suppressed to a minimum even if the seedling stand 5 protrudes largely to the side at the end of the lateral movement.

Further, since the slide pieces 7, 7 and the marker operating levers 15, 15 are supported by the same mounting seats 9, 9, the support structure is simplified, and the weight and cost of the rear part of the machine body can be reduced.

(g) Effects of the invention Since the invention is configured as described above, the slide pieces 7, 7 supporting the upper part of the seedling platform 5 that reciprocates laterally, and the marker operating levers 15, 15.
and can be attached to the same mounting seats 9, 9, simplifying the structure of the support member, thereby reducing the weight and cost of the rear part of the fuselage 1, and moreover, the seedling stand 5
is supported on the outside of the handles 8, 8, so when the seedling stand 5 moves laterally, its vibrations are suppressed even though it protrudes outward to a large extent, thereby improving maneuverability. It is possible to suppress compaction of the seedling soil due to vibration.
