Description

[Detailed description of the invention] A rice transplanter is used to plant seedlings by driving through rice fields, and for its running performance, it is required to have a lightweight body, a low center of gravity, and a good view of the road ahead. However, in recent years, with the improvement of work efficiency, a spare seedling stand has been installed above the machine, and spare seedlings are placed on this.
Efforts have been made to allow timely transfer to the planting department.

However, conventional spare seedling mounting stands have either a wide bonnet with a flat mounting section formed on the top, or a separate frame assembled on top of the bonnet and placed on it. There are some that can be used as a stand, but because the machine is unstable when traveling, the bonnet is deformed and the spare seedling box becomes loose, and it is inconvenient to replenish the spare seedling box.

In the present invention, the bonnet is formed to be narrower than the seedling box, and the upper surface of the bonnet is recessed in the middle part in the longitudinal direction over the entire width to form a recess between the front high part and the rear high part. A spare seedling box mounting part is provided between the rear high part and the concave part, and a space is provided below the bottom of the seedling box, and a spare seedling box is placed in a low front and rear high manner. Relatively narrow guide pieces are provided on both left and right sides of the spare seedling box to restrict the sides of the seedling box, so that the left and right sides of the spare seedling box can be held between the guide pieces. Although it has a simple configuration, it eliminates the defects in running performance, and
This was invented to improve work efficiency when replenishing spare seedlings.

To explain an embodiment of the structure of the present invention shown in the drawings, 1 is a body frame of a rice transplanter;
An engine 2 is mounted in the front of the body frame 1, and a driving operation handle 3 is provided at the rear of the body frame 1 extending rearward and diagonally upward. Reference numeral 4 denotes a seedling mounting table, which is installed along the inclination of the operation handle 3 in a manner that is low in the front and high in the rear, and is configured to reciprocate from side to side by a drive mechanism 5. 6 is a planting device, which is provided in front of the seedling mounting table 4. Reference numeral 7 denotes wheels, which are supported on the ends of a transmission case 8 which protrudes left and right from the transmission case, so that they can swing. 9 is the plane sliding body, and the fuselage frame 1
It is attached freely up and down. Reference numeral 10 denotes a bonnet that extends from the engine 2 mounted at the front of the fuselage 1 to the vicinity of the planting device 6 at the rear of the fuselage 1 and covers the upper part thereof, and is made of synthetic resin.

Incidentally, the bonnet 10 is formed to be narrower than the seedling box 12, and is recessed halfway in the longitudinal direction of the upper surface over the entire width. A concave portion 10b is integrally formed by the high portion 10a and the rear high portion 10c. Then, on the top surface of the bonnet, there is a spare seedling box mounting part A for placing the spare seedling box 12 on the front bottom, extending between the rear high part 10c and the recessed part 10b, with a space B below the bottom of the seedling box. It is formed. In the illustrated example, the recess 10b is connected to the bonnet 1.
As shown in FIG. 5, the recessed portion 10b is provided with stepped portions 10d on both left and right edges over the entire length thereof. In addition, when the spare seedling box 12 is placed between the recessed part 10b and the rear high part 10c, the spare seedling box 12 is placed on the wheels 7.
It is located almost directly above the center of gravity, and care has been taken to prevent the center of gravity from changing back and forth. Also,
The upper surface of the front height part 10a of the bonnet 10 is a rounded surface that gradually becomes higher from the tip to the rear end when viewed from the side, and the upper surface of the rear higher part 10c is a rounded surface that gradually becomes lower from the tip to the rear end. The upper surface of the bonnet as a whole has a gently curved shape with a radiused surface omitted only in the recessed portion 10b, resulting in a bonnet shape with enhanced design effect.

Reference numeral 11 denotes a narrow guide piece whose base is attached to the stepped portion 10d, and is provided protruding outward from the left and right sides of the bonnet 10, and a vertical piece 11b is integrally formed with the upwardly inclined portion 11a at its outer tip. ing. Furthermore, a square hole 11c is bored in the inclined portion 11a, and a stopper 11d is provided at the front edge of the square hole 11c.
is projected upward. Also, the above guide piece 11
The inner widths of the upright pieces 11b, 11b are set to match the outer widths of the left and right sides 12b, 12b of the spare seedling box 12, and are designed to clamp the spare seedling box 12 and prevent lateral displacement due to machine body vibration, etc. It's getting old.

Reference numeral 13 denotes side markers provided on both left and right sides of the front portion of the bonnet 10, which serve as directional markers when driving.

The present invention is constructed as described above, and when planting seedlings, pine seedlings (not shown) are placed on the seedling mounting table 4. Next, the spare seedling box 12 containing the spare pine seedlings c is placed on the spare seedling box placement part A, but at this time, as shown in FIG. The seedling box 12 is supported at two points by the concave part 10b on the front end side and by the rear high part 10c on the rear side. Although the seedling box 12 is positioned with the front and back raised and a space B maintained below the bottom of the seedling box, forward sliding of the seedling box 12 is regulated by the rising part 10e, and the side part 1 of the seedling box
2b is attached and held between the left and right guide pieces 11, so that the seedling box 12 is positioned and held in an extremely stable forward tilted state on the preliminary seedling box mounting part A, and does not swing due to vibrations of the machine body or the like.

When the remaining seedlings on the seedling table 4 run out during the planting process, the preliminary seedling box 12 is pulled out as shown in FIGS. 4 and 5, and the tip of the preliminary seedling box 12 is inserted into the square hole 11c. and stopper 1.
1d and with the rear part of the seedling box placed on the rear high part 10c, remove the preliminary seedlings c from the rear with the scraper 14.
and the bottom of the box, transfer the seedlings onto the scraper 14, and transfer them to the seedling mounting table 4. When inserting the scraper 14, the tip of the preliminary seedling box 12 is locked by the square hole 11c and the stopper 11d, and the preliminary seedling box 12 is held in a stable state without slipping forward, so that seedlings can be removed. is something that can be done easily.

In addition, even if the spare seedling box 12 is placed on the spare seedling box placement part A, the center of gravity is also lower at the bottom due to the formation of the recessed part 12, compared to a case where a frame for placing the spare seedlings is provided above the bonnet. This makes the running performance even better, and since the forward view is not obstructed by the spare seedling box 12, proper planting work can be carried out.

In this way, the present invention provides a bonnet that covers the area from the engine mounted at the front of the aircraft to the vicinity of the seedling planting operation unit installed at the rear of the aircraft, and the bonnet is formed to be narrower than the seedling box. At the same time,
The middle part of the top surface of the bonnet in the longitudinal direction is recessed over the entire width to form a recess between the front high part and the rear high part, and the spare seedling box is placed between the rear high part and the recess with a space below the bottom of the seedling box. A spare seedling box placement part is provided to place the spare seedling box in a manner that the front is low and the back high. Since the guide piece is provided so as to protrude laterally, the spare seedling box is placed in a stable state with a low center of gravity and a low center of gravity during traveling operations.
Since the front view is not obstructed by the spare seedling box, good planting work can always be carried out. In addition, when replacing the spare seedling box, the rear side of the spare seedling box is in a high position, the bonnet width is narrower than the box width, and space is maintained below the seedling box, so it is easy to reach and place the spare seedling box. This greatly reduces the contact resistance of the seedling box to the front and back, making it easy and quick to take in and out the spare seedling box.The front and back of the spare seedling box are supported at two points: the concave part and the rear high part. Therefore, even if the bonnet is deformed, there will be no play, and the spare seedling box can always be placed in a stable state.In addition, the width of the spare seedling box is held between the guide pieces, so it will not shift sideways due to vibration or impact of the machine. In addition, since the tip of the recessed portion acts as a stopper, it is possible to prevent the preliminary seedling box from sliding forward due to vibration or the like.

Furthermore, since the spare seedling box is held in a low front and high back position, when transferring spare seedlings to the seedling stand, it is easy to insert the scraper from the rear and take out the seedlings, which further improves work efficiency. play.
