Description

TECHNICAL FIELD The present invention relates to a structure of a walk-behind rice transplanter.

2. Description of the Related Art Conventionally, there was a walk-type rice transplanter as disclosed in Japanese Utility Model Laid-Open No. Sho 58-24115. In this conventional technique, a preliminary seedling placing base is integrally formed on the bonnet.

Problems to be Solved by the Invention In the conventional type, the load of the preliminary seedling is applied to the bonnet itself, and since the bonnet is generally made of synthetic resin, there is a problem in strength, and particularly when the bonnet itself is largely projected. Not only the problem of strength remains, but also the cost of manufacturing the mold increases, which leads to an increase in cost. On the other hand, unless the rear side of the bonnet is largely projected upward, the preliminary seedling cannot be raised backward and tilted, which makes it inconvenient for the operator to mount or take out seedlings. Occurs.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention extends a frame 5 from the traveling power transmission case 1 at the front part toward the rear in the lower left and right center, and the rear of the frame is arranged at the upper rear. The operation handle 12 is divided into left and right at the upper end thereof, the wheel transmission cases 3, 3 are extended rearward from the left and right sides of the traveling transmission case 1, and the paddy wheel 4, 4, is provided outside the case. 4 is mounted so that the wheels swing while being transmitted and rotated on both sides of the frame 5, and the seedling table 9 which is inclined in a form along this frame is provided on the front side of the rising portion on the rear side of the frame 5 Is attached to the frame side so as to be freely movable, and a planting transmission case 6 whose side view rises upward and rearward is attached slightly forward of the rear bent portion of the frame. 6
The seedling planting tools 8, 8 are attached to the left and right sides of the lower part of the plant, and the projecting frame 16 is attached to the upper part of the planting transmission case 6 so that the side view is directed forward and upward.
The upper surface of the protruding frame is formed with a recess 16a so that the seedling raising box 4 can be fitted in the rear view, and the machine body cover 14 is provided on the upper part of the frame 5 so that the front side rises upward from the front-rear intermediate part. A seedling-raising-box-mounting portion is formed by abutting the leading end of the seedling-raising box to the rising base end portion 14a of the cover 14 and fitting the rear bottom surface into the recess 16a, and the projecting frame.
A walk-type rice transplanter was constructed by forming a hole 17 penetrating in the front-rear direction in 16 so that an operation lever, a cord of a recoil starter or the like can be inserted and supported.

EFFECTS AND EFFECTS OF THE INVENTION According to the present invention, although the spare seedling can be placed above the machine frame between the left and right wheels, the weight of the spare seedling is a machine body cover.
Both the 14 and the planting transmission case 6 can separately support each other, and the rear side of the spare seedling to be placed can be raised to facilitate the operator to take out the spare seedling from the seedling stand 9. Also,
Since the projecting frame 16 that supports the rear of the spare seedling has holes through which the change lever shaft and the starter rope of the engine can be inserted, no special member for supporting and guiding these is required, and the configuration is simplified. Can be converted.

Embodiment One embodiment of the present invention will be described in detail with reference to the drawings.

Reference numeral 1 is a traveling transmission case. An engine 2 is mounted on the front side of the traveling transmission case 1. Reference numeral 3 denotes a chain case, which is rotatably mounted on the left and right sides of the traveling transmission case 1 on the inner side at the front end side, and has a paddy wheel 4 axially attached to the outer side on the rear end side for transmission rotation.

The left and right chain cases 3, 3 are provided so as to be vertically rotated by a hydraulic device (not shown).

Reference numeral 5 denotes a frame, the base end side of which is fixedly attached to the lower end side of the rear surface of the traveling transmission case 1 and extends rearward in a substantially horizontal shape, and is bent downward from the intermediate portion extending rearward toward the rear upper side.

Reference numeral 6 denotes a planted transmission case, which is attached to the front portion of the bent portion of the frame 5 by a bolt 7 so that the lower end portion is held from above. Then, the planted transmission case 6 is separately manufactured into a lower case 6a for mounting the transplant tool 8 and an upper case 6b for internally mounting a mechanism section for operating the seedling mounting table 9, and the both cases are connected to each other.

The seedling placing table 9 is arranged along the front side of the frame 5 which is directed rearward and upward, and is supported so as to be movable in the left-right direction from the frame side. Then, a connecting member is attached to the moving shaft 10 protruding in the left-right direction from the inside of the planted transmission case 6.
The seedling table 9 is connected by 11 so that the seedling table 9 can be reciprocated left and right.

 Reference numeral 12 indicates a steering wheel, and 13 indicates a leveling float.

Reference numeral 14 denotes an airframe cover, which is made of synthetic resin and has a front portion that bulges upward to cover the engine 2 and the fuel tank. It is provided in a shape. The width of the left and right is about 35 cm, which is slightly wider than the width of the mat seedlings that are normally grown in boxes, and the width that the seedling boxes can be placed on. The body cover 14 has a front portion fixed to a ban bar 15 fixed to the engine 2 and a rear portion attached to the planted transmission case 6.

Reference numeral 16 denotes a projecting frame, which is fixed to the upper part of the planted transmission case 6 and faces forward and upward in a side view, and the upper surface of the projecting frame 16 is recessed so that the nursery box can be fitted in the rear view.
forming a. The projecting frame 16 has holes 17a and 17b penetrating therethrough in which the operation lever shaft 18 and the cord 19 of the recoil starter can be inserted and supported in the front-rear direction. Then, the leading end of the seedling raising box A is brought into contact with the rising base end of the machine body cover 14 and the rear bottom surface is fitted into the recess 16a of the projecting frame 16 so that the seedling raising box A can be placed.

In the rice transplanter thus configured, the nursery box A as a spare seedling can be reliably placed by the machine cover 14 and the projecting frame 16, and the rear end side of the placed nursery box A is It is located at a high position on the front side of the seedling placing table 9 so that it can be easily taken out from the operator side to facilitate seedling replenishment, and moreover, an operating tool is appropriately arranged between the placed seedling raising box A and the seedling placing table 9. Since it can be installed and the supporting frame can also serve as the projecting frame, the structure is simplified.
