Description

[Detailed description of the invention] The present invention is a seedling feeding device for a rice transplanter configured to replenish mat seedlings from a spare seedling holder to a main seedling holder that supplies mat seedlings to the planting claws. A main seedling resting stand tilted forward is provided in front of the handle, a spare seedling resting stand that is rotatable around a horizontal axis is provided above the main seedling holding stand, and the spare seedling holding stand is placed in a substantially horizontal position. The structure is such that it can be freely switched between a preliminary seedling holding position and an inclined seedling supplying position in which one end of the preliminary seedling rest is overlapped with the upper end of the main seedling rest, and the preliminary seedling rest has a handle that protrudes toward the control section. The present invention relates to a seedling supply device for a rice transplanter, which is provided so that the attitude of the preliminary seedling stand can be changed from a control position.

In the seedling supply device of the rice transplanter as described above, when supplying the preliminary seedlings from the preliminary seedling tray whose position has been changed so as to be aligned with the main seedling tray, the preliminary seedlings are brought into close contact with the preliminary seedling tray, Since it was difficult for the operator to hold the part above the bed, he had no choice but to pull out the seedlings and supply the seedlings by holding the seedlings. There was a problem in that mat seedlings were easily damaged accidentally.

In view of these circumstances, the present invention aims to solve the above-mentioned problems by making it possible to have a mat seedbed section.

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

A wheel transmission case 4 has propulsion wheels 3, 3 rotatably mounted on both left and right sides of a traveling gear transmission case 2, which is configured to transmit the output of an engine mounted at the front of the aircraft.
, 4 are pivotally connected to each other so as to be able to swing up and down about the horizontal axis, and a main seedling stand 5 for loading mat seedlings is attached to the rear of the machine so as to move back and forth from side to side, and the planting claws 6 are moved along an elliptical trajectory. A float 7, which is long in the longitudinal direction of the fuselage, is connected to the fuselage so that its front end can swing up and down with the rear end as the center. 7.
Due to the buoyancy of ... and the ground reaction force of the wheels 3, 3,
The seedling planting section 8 is configured to maintain a constant height of the mud surface, and while the machine is advanced by the propulsion wheels 3, 3, the seedling planting claw 6 is used to remove one seedling block from the mat seedlings. A walking type rice transplanter is installed to take out the rice and plant it at a certain depth below the mud surface.

The main seedling rest 5 is arranged in a forward-leaning position, and the preliminary seedling rest 9 is placed in a position above the front of the main seedling rest 5.
is configured to be able to freely swing back and forth around the horizontal axis X, and can be switched between a substantially horizontal preliminary seedling holding position and an inclined seedling supplying position in which one end thereof is connected to the upper end of the main seedling resting table 5. It is organized.

A projection 10 having a seedling lifting surface a is formed on the upper end of the main seedling rest 5 at an appropriate interval in the lateral direction, and the relay tongue portion 9a of the preliminary seedling rest 9 is provided with the projections 10 having a seedling lifting surface a. Hole 11 into which the protrusion 10 can enter
In the above-mentioned supplying posture of the preliminary seedling stand 9,
The feeding end side of the preliminary mat seedling A can be lifted from its tongue portion 9a.

Reference numeral 13 denotes a handle for changing the posture attached to the preliminary seedling stand 9, and extends toward the control section side.

Therefore, the operator extends his arm from between the control handles 12 and holds the raised front edge of the floor of the mat seedling A for replenishment and pulls it down to the main seedling resting stand 5 side. Seedlings can be easily and quickly replenished without damaging A.

In addition, as a structure for floating the feeding end side of the mat seedlings A loaded on the preliminary seedling resting stand 9, the projections 10 are made of elastic projections, so that the resistance to seedling supply due to these projections is reduced. You may do so.

In addition, the lifting members are arranged to rise to their operating positions in conjunction with the swinging of the preliminary seedling resting table 9 to the seedling supplying position, and furthermore, these lifting members are locally provided and operated. The shape and form of the mat can be modified in various ways, such as by arranging to lift the spare mat seedlings only within the range that a person's hands can fit into, and these are collectively referred to as a lifting mechanism.

In summary, the present invention provides the seedling feeding device of the rice transplanter described at the beginning, in which the lower end of the preliminary seedling tray in the inclined seedling supplying position is connected to the upper end of the main seedling tray. The present invention is characterized by being provided with a lifting mechanism for lifting the feeding side end of the mat seedlings on the placing stand from the seedling placement surface.

In other words, since the front edge of the supplied seedlings can be raised above the seedling placement surface, it is possible to hold the floor part, and the seedlings can be replenished easily and quickly.
