Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a riding type rice transplanter in which a multi-row seedling transplanter is attached to the rear of a riding type tractor.

(Prior art) Conventionally, as disclosed in Japanese Utility Model Application No. 53-107511, a multi-row seedling planting machine is attached to the rear of a single-passenger type tractor, and the seedling mounting table of the seedling planting machine is It is well known that a large riding type rice transplanter whose left and right width extends outwards considerably more than the left and right width of the towing vehicle has a cover that covers the upper part of the rear wheels.

However, the conventional rear wheel cover is only slightly wider than the outer end of the wheel, and there is no wide rear wheel cover that extends close to the seedling table of the seedling transplanter attached to the rear.

(Problems to be Solved by the Invention) In conventional riding-type rice transplanters, when replenishing seedlings from the towing vehicle side to the seedling mounting platform on the left and right outer ends of the seedling transplanter, the lateral width of the towing vehicle is narrow. Therefore, it was extremely difficult.

Also, to facilitate the supply of seedlings to the seedling table.

It was considered to install a step for replenishing seedlings on the outside of the rear wheel, but this was extremely inconvenient as the step would have to be removed each time the wheel was replaced or the mud that adhered to the wheel was removed. Met.

(Means for Solving the Problems) In order to solve the problems of the above-mentioned prior art, the present invention provides a rear part of a passenger towing vehicle 1 having a front wheel 10.10 and a pair of left and right rear wheels 11.11. The seedling mounting table 22 is tilted so that the front side is located upward, and is divided into a plurality of parts in the left-right direction and moves back and forth horizontally, and the rear lower end side of each of these divided seedling mounting tables 22a. A seedling planting machine 20 having a seedling planting device 23 that divides the seedlings one by one and plants them on the soil surface facing the seedling table 20 is installed, and when the seedling table 22 is stopped at the center of the left and right sides, the seedling table 22 is The total left and right width of is the towing vehicle 1.
In a riding type rice transplanter in which the distance between the outer ends of the rear wheels is wider than that of the rear wheels, the cover 15 covering the upper part of the rear wheels of the towing vehicle 1 is extended outward to near the outer end of the seedling mounting table 22. It was made into a model rice transplanter.

(Operations and Effects of the Invention) According to the present invention, the cover covering the upper part of the rear wheel is extended in the left-right direction to near the outer end when the seedling table stops at the center of the left and right positions. When riding, you can easily reach the seedling trays on the left and right outer ends, allowing you to replenish seedlings from the towing vehicle.Furthermore, the cover does not get in the way when attaching or detaching the rear wheels. It has the effect of making mud removal work easier.

(Embodiment) The engine frame 5 is connected to the front part of the mid transmission case 2 by a plug 4 and fixed to the front part.

6 indicates the engine, and 7 indicates the bonnet. Reference numeral 8 denotes a front transmission case, which is integrally fixed to the lower side of the engine frame 5. Reference numeral 9 denotes a front differential case, which is rotatably supported by front and rear brackets attached to the engine frame 5. Reference numeral 10 denotes a front axle, which is attached to both left and right sides of the front differential case 9 via a front axle case. 11 is a rear wheel, and the rear transmission case 3
It is installed on both the left and right sides of the rear axle through the rear axle case.

12 is a control handle, and 13 is a control seat.

Reference numeral 14 denotes a step platform, which is stretched over the upper side of the vehicle body 1a and is widely provided over the entire periphery of the bonnet 7 and the entire periphery of the support frame 13a of the seat 13.

A wheel cover 15 is formed on both left and right sides of the rear end side of the step stand 14 by a surface 15a facing rearward and upward and a horizontal surface 15b so as to cover the front side and upper part of the rear wheel 11.

Reference numeral 16 denotes a support frame that supports a pole 18 to which a spare seedling placement stand 17 is attached, and its base is fixed to the side of the vehicle body 1a, and this support frame 16 supports the step stand 14. .

Reference numeral 19 denotes a cover reinforcing frame, the base of which is fixed to the support frame 16, and whose tip end extends along the outer back surface of the wheel cover 15 to support the cover 15.

Reference numeral 20 denotes a seedling planting machine, in which a seedling mounting table 22 divided into a plurality of left and right sections is supported on the upper front side of a planting transmission case 21, which also serves as a machine frame, so as to be able to move horizontally in a reciprocating manner. A seedling planting device 23 is provided for dividing and planting seedlings in batches from each of the seedling mounting tables 22a, 22a, . . The seedling planting machine 20 is mounted so as to be movable up and down from the towing vehicle 1a side using an elevating link mechanism 25.

It is attached to the machine frame side of the seedling planting machine 20, and is configured in a loop shape so as to surround the left and right outer sides and the upper part of the seedling mounting table 22, which reciprocates left and right. When replenishing seedlings to the seedling tray, use one hand to prevent the worker from accidentally falling backwards, or use the handrail to hold the seedling table 2.
When the user extends his/her body toward the second side, the user can reach the lower end of the seedling table 22 and adjust the levitation of the seedlings.

According to the configuration on the upper side, during seedling planting, the seedling mounting table 22
When the number of seedlings on the top is running low and it is time to replenish the seedlings, a worker riding on the tractor 1 takes out the seedlings that have been placed on the preliminary seedling placement table 17 and moves them to the rear of the step table 14. , supplies the carried seedlings to the seedling mounting table 22. At this time, the supply to the one helmet device stand 22a at the left and right lateral ends is carried out by the rear wheel 11.
Cover 15
It's best to move up and replenish.

That is, since the cover 15 is extended long toward the left and right sides, when the user rides on the cover 15, the seedling table 22 at the outer end can be reached sufficiently, and the seedlings can be easily replenished.
