Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter in which a protector is provided at the front of the lateral end of a sliding frame that receives and supports the lower end of a seedling stand that is reciprocated laterally at a constant stroke.

According to the above-mentioned rice transplanter, by providing the protector, it is possible to prevent the lateral end of the sliding frame, which protrudes outward from the side of the machine, from being deformed and damaged due to contact with other objects. The present invention is a rice transplanter having such advantages, in which the side edges of the sliding frame and the protector are installed so that the width of the machine can be made compact when traveling on the road or when storing the machine in a warehouse. It is intended to be able to be stored to the inside of the aircraft with a simple operation.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

As shown in Figures 1 to 3, a pair of left and right front propulsion wheels 1, 1 that can be operated to change direction, a pair of left and right rear propulsion wheels 2, 2, a front engine 3, a transmission case 4, and a rear driver's seat. 5. At the rear of the vehicle body equipped with a steering handle 6, etc., there is a slanted seedling stand 7 which is moved back and forth horizontally at a constant stroke with five pine-shaped seedlings W... placed side by side in a horizontal direction; Seedling planting with five planting claws 8, which sequentially take out and plant seedlings one by one from the lower end of the seedling W..., a plurality of horizontally arranged soil leveling floats 9, etc. After installing the device 10, as the aircraft progresses, 5
It is configured to plant seedlings in rows.

As shown in FIGS. 1 and 5, a pair of left and right lower links 11, 11 are provided at the rear of the vehicle body, and
One upper link 12 is connected in a vertically swingable manner,
The seedling planting device 10 is pivotally connected to a frame 13 that pivotally connects the rear end portions of each link 11, 11, 12 so as to be relatively swingable around the longitudinal axis X, and the lower links 11, 11 A hydraulic cylinder 14 is provided for lifting and lowering the seedling planting device with respect to the vehicle body, and a seedling planting device swing regulating rod 15 is connected to the seedling planting device side frame 16 at its base end.
The engagement hole 17 provided in the frame 13 at the tip thereof is pivoted so as to be swingable back and forth and up and down.
A locking portion 15a that removably engages with the seedling planting device frame 1 is provided in a bent state.
6 is provided with a hook 18 that engages and supports the rod 15 in the disengaged state.
The seedling planting device is configured so that it can be raised and lowered relative to the vehicle body in order to maintain a constant planting depth and avoid contact with the ground when driving on the road. The seedling planting device 10 is configured to be able to swing left and right following the field, and is further configured to prevent the seedling planting device 10 from swinging left and right using a rod 15 when traveling on the road.

As shown in FIG. 3, a plurality of seedling receiving portions a are arranged intermittently in the longitudinal direction on a rod-shaped seedling stay 19 for preventing the pine-shaped seedlings W placed on the seedling platform 7 from floating. Form in the state, attach, and seedling stay 1
9, compared to forming a series of seedling receiving portions over the entire length thereof, it is possible to prevent the seedlings W from floating without providing a large resistance to the movement of the seedlings W. Note that the seedling stay 19 may be formed using a plate-shaped body in an upright position. 20 in the figure is a seedling amount detection sensor for activating an alarm device that is energized to protrude upward when the amount of seedlings falls below a certain level, and is connected to one of the plurality of seedling receiving parts a. It is placed facing the.

As shown in FIGS. 2 to 4, a rod-shaped protector 22 is installed at the front of the lateral end of the sliding frame 21 that receives and supports the lower end of the seedling stand 7 in the working position and inside the machine. The protector support frame 23 is provided with a groove 25 for engaging the protector fixing bolt 24, and the protector support frame 23 has a groove 25 for engaging the protector fixing bolt 24. The lateral end portion 21a of the moving frame 21 is provided in a state in which it is separably pin-fitted to the main body portion,
A plate-shaped body 26 is installed so that the sliding frame lateral end portion 21a can be switched between an operating posture connected to the main body and a retracted posture located further inside the body when changing its posture with respect to the protector 22. During installation and planting using the rear extending portion 22a of the protector 22, the sliding frame lateral end portion 21a protruding outward from the side of the machine body will be deformed and damaged due to contact with other objects. It is configured to avoid this, and when traveling on the road or storing the aircraft in a warehouse,
By switching the sliding frame lateral end 21a and the protector 22 to the retracted position, the width of the aircraft body can be made compact.
The posture switching operation for each of the protector 1a and the protector 22 can be easily performed all at once.

In addition, the present invention can be applied to a sliding frame for supporting a seedling stand installed in a traveling type rice transplanter as well as a riding type rice transplanter. The structure for attaching the moving frame lateral end portion 21a to the protector 22 can be modified in various ways.

In summary, the present invention, in the rice transplanter mentioned above,
The lateral end portion 21a of the sliding frame 21 is provided so as to be freely separable from the main body portion, and the protector 22
is provided so as to be switchable between an operating position and a retracted position located on the inside of the fuselage, and the sliding frame lateral end 21a is moved relative to the protector 22 when the main body part It is characterized in that it is installed so that it can be switched between an operating position that is connected to the main body, and a retracted position that is located further inside the fuselage.

That is, the protector 22 can be switched between the operating position and the retracted position located further inside the body, and the sliding frame lateral end 21a is separable from the sliding frame main body. , because it is designed to be able to switch between a working position that is connected to the main body and a retracted position that is located further inside the fuselage.
By switching each of the protector 22 and the sliding frame lateral end 21a to the retracted position and making the width of the aircraft compact, it is possible to avoid contact with other objects when driving on the road, for example, or to store the aircraft in a warehouse. This provides various advantages, such as being able to store it in a small space. In particular, according to the present invention, the sliding frame lateral end 21a is attached to the protector 22 so that it can be switched between the working position and the retracted position as the position of the protector 22 is changed. Compared to supporting the part 21a on the aircraft body so that the attitude can be changed separately from the protector 22, the attitude switching operation for each of the protector 22 and the sliding frame lateral end 21a can be easily performed in one operation. This is a great practical advantage.
