Description

[Detailed Description of the Invention] The present invention relates to a spare seedling stand mounting structure for a rice transplanter.

If the space above the bonnet that covers the driving part is to be used effectively to provide a stand for spare seedlings, it must be placed at a high position using a stay, etc. in order to install it so that opening and closing of the bonnet will not be hindered. First, this has the disadvantage that the front view is obstructed, so conventionally, it has generally been provided integrally with the bonnet. However, there was a drawback that the bonnet was bent and deformed due to the full weight of the spare seedlings placed thereon.

In view of the above points, the present invention makes effective use of the space above the bonnet to provide a stand for placing spare seedlings, while also making it possible to lower the position of the stand and to prevent deformation and damage of the bonnet due to the weight of the spare seedlings. The purpose is to suppress the

In order to achieve the above-mentioned purpose, the preliminary seedling stand mounting structure of the rice transplanter according to the present invention is configured such that the bonnet for the driving unit located at the front of the machine body can swing open and close using the rear end as a fulcrum. ,
A support frame is provided at a position rearward from the vicinity of the driving unit, with both front and rear ends fixed to the aircraft body,
A horizontal pivot shaft that serves as a fulcrum for the bonnet is provided near the rear end of this support frame, and the rear end of the preliminary seedling stand is pivoted to the support frame while being located above the bonnet. By connecting and applying force to the front side of the pivot connection part of this preliminary seedling rest against the upper surface of the bonnet, the preliminary seedling rest can be moved as the bonnet is lifted and swung open. It is characterized in that it is configured to be able to move upward and oscillate.

In other words, the swinging fulcrum of the bonnet is located as far back as possible, and even if the swinging angle is small, the bonnet can be opened wide to the driving part, and the preliminary seedling stand can be pivoted to the support frame on which the swinging fulcrum is formed. Support me,
When the bonnet is opened, the auxiliary seedling rest is also raised and swung by contact with the bonnet, and the bonnet can be opened without being obstructed by the auxiliary seedling rest.

Therefore, although the space above the bonnet is utilized to provide a spare seedling stand, the spare seedling stand can be provided at a low position close to the top of the bonnet to improve visibility. When the bonnet is closed, the weight of the stand with spare seedlings placed on it is also borne by the support frame.
The weight on the bonnet can be reduced compared to the conventional method, and by setting the pivot shaft close to the axis of the spare seedling stand, almost the entire weight can be borne by the support frame itself, making it easier to place the seedlings. It is possible to prevent the bonnet from being deformed or damaged due to the weight of the spare seedlings placed there.

Furthermore, since bonnets are usually made of thin plate material, they tend to resonate with driving and engine vibrations, causing unpleasant chattering noises. There is also the advantage that the vibration damping effect produced by this can suppress the chattering noise.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

A driving unit 2 is mounted on the front part of the fuselage frame 1, and a seedling planting device 3 and a handle 4 are provided at the rear.
In addition, a pair of left and right running transmission cases 6, 6 each carrying wheels 5 are pivotally connected to the machine frame 1 so as to be able to swing up and down about the left and right axis of the machine, thereby configuring a walking rice transplanter. be.

The driving unit 2 includes an engine 7, a transmission case 8, and a belt type transmission device 9 that spans both 7 and 8.
It consists of a bonnet 1 above it.
Covered with 0.

A hydraulic cylinder 11 is connected to a transmission case 8 which is also used as a part of the fuselage frame 1, and left and right support frames 12a, 12a are extended from the transmission case 8 in the left and right direction of the fuselage. From both ends of 12a, 12a to the rear, there is a support frame 12 shaped like a letter in side view.
b, 12b are extended, and a pivot shaft 13 is provided at the rear end side of each of the front-rear support frames 12b, 12b to protrude inward of the body, and both pivot shafts 13,
A bonnet 10 is pivotally connected to each of the bonnets 13 so as to be able to swing open and close.

The left and right support frames 12a, 12a and the front and rear support frames 12b, 12b are collectively referred to as a support frame 12.

A preliminary seedling rest 14 is swingably provided at the top of each of the front and rear support frames 12b, 12b, and a tension spring 15 is stretched across the preliminary seedling rest 14 and the front and rear support frames 12b, 12b. The front side of the preliminary seedling stand 14 is urged to swing downward, and the bonnet 1 is
A protrusion 16 for receiving and supporting the lower surface of the front end side of the preliminary seedling stand 14 is provided in series at a predetermined location of 0.

As clearly shown in FIG. 3, a wire clamp member 18 with bendable clamp pieces 17 protruding from a flat plate is attached to the upper and lower middle of the handle 4, as shown in FIG. The clutch, the valve for the cylinder 11, and the swinging arm 19 that raises and lowers the left and right wheels 5, 6 in opposite directions are held by the lock pins that fix the cylinder rod 11a. The configuration is simple and can be performed at low cost.

FIG. 4 shows another embodiment, in which the support frame 12 is configured by integrally connecting the rear ends of the front and rear support frames 12b and 12b with a horizontal frame 12c, and the front and rear support frames 12b and 12b
A bracket 21 to which the pivot shaft 13 of the bonnet 10 is connected is bored at the rear end of each. Further, a support member 22 is provided projecting from the upper part of the transmission case 8 to receive and support the bonnet 10 in the closed state.

Even in this case, when opening the bonnet 10,
Place the bonnet 10 in contact with the stand 14 for seedlings and place the bonnet 1 while swinging the stand 14 for seedlings.
