Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rice transplanter with a fertilizer application, which has three or more planting mechanisms and has a fertilizer application device for each.

[Conventional technology]

In this type of fertilizer applicator rice transplanter, for example, in the case of arranging the hopper for the fertilizer applicator, in the one disclosed in Japanese Utility Model Publication No. 59-77318, two hoppers are provided on the lateral outer side of the machine and the machine. They were arranged side by side in the front-back direction.

[Problems to be solved by the invention]

Therefore, in such a case, it is necessary to apply fertilizer from the hopper located on the rear side to the inner planting strip and apply fertilizer from the hopper located on the front side to the outer planting strip from the hopper. It is better to make both the downflow paths up to the shortest, but it is still better, but nevertheless, the middle position of the hopper in the machine front-rear direction is set to the fertilization position (groover) so that both downflow paths are approximately equal. Even if it is taken, the feeding mechanism is displaced forward and backward from the fertilizer application position.Therefore, the flow-down path must be longer than when the hopper (feeding mechanism) is located immediately above the fertilizer application position. It was in a situation where it was easy for clogging to occur.

An object of the present invention is to provide an arrangement of a hopper with less clogging in a downflow path, and to provide an auxiliary seedling stand provided above the hopper at a position as low as possible.

[Means for solving problems]

The characteristic configuration according to the present invention is that a center hopper is provided at the center of the machine body and left and right side hoppers are provided on both lateral sides of the center hopper to provide a fertilizer hopper group, and an upward opening portion of the side hopper is provided with a tip portion. At the center of the machine width direction and at the pivotal end on the outside of the machine width direction at the swing opening / closing lid, and at the same time as installing a seedling stand above the side hopper, The point is that the seedling mounting frame of the stand is installed in an inclined posture that is positioned downward as it is located closer to the center of the machine width. Its effects are as follows.

[Action]

(A) Due to the characteristic configuration, the fertilizer application hoppers are arranged side by side in a row so as to correspond to the plurality of planting ridges provided along the lateral direction of the machine. It is possible to arrange a hopper that is almost directly above, and set the fertilizer drop path from the hopper to the groover to the shortest length.

(B) According to the characteristic configuration, the point at which the seedling placing frame is attached in an inclined posture and the lid of the side hopper are made swinging open / close type, and the inclination direction of the seedling placing frame and the opening / closing direction of the lid are set rationally. , The center of the body width of the seedling placing frame can be placed close to the tip of the lid of the side hopper, and the seedling placing frame can be placed in a lower position even above the side hopper, and the seedling placing frame can be placed in the lid. Since the tilted posture is in a higher position as the opening degree increases, the lid can be erected almost straight up as shown in the drawing, and the opening degree can be increased.

[Effect of device]

As a result, it is possible to easily replenish fertilizer,
The preliminary seedling stand can also be placed in a low position, and it is easy to scoop mat seedlings with a scooping plate to transfer from this preliminary seedling stand to the seedling stand.

On the other hand, with respect to the center hopper (14), a cross-shaped plate-like frame (24) is erected from the transmission case (3) that power-connects the mission case (2) and the center planting case (4). ,
Install the center hopper (14) by supporting one side of the feeding cases (16A), (16A) of the feeding mechanisms (16), (16) located on both sides of the horizontal part of the plate frame (24). Forming a structure. As described above, since the supporting frames (23) and (24) support the feeding cases (16A) and (16A) only from one side, they are provided in the feeding cases (16A) and (16A). The brush (39) for sliding contact with the feeding rotor (not shown) can be provided on a side surface different from the side where the support frame (23) is present, so that the brush (39) can be easily attached and detached.

The fertilizer application device (11) fixed and supported by the machine body as described above has the following feeding drive system. Although not shown, the feeding mechanism (16) is provided with a feeding rotor for feeding the fertilizer in the case (16A), and a rotor shaft (25) for rotationally driving the feeding rotor is provided from the case (16A) to the rear of the fuselage. It has been extended toward. Then, as shown in FIG. 3, a triangular drive member (26) is fixed to the side hopper (15) side rotor shaft (25) and a swing arm of the side side seedling planting mechanism (7). A connecting rod (27) is erected from the drive member (26). Also, the two rotor shafts (25) on the side of the center hopper (14),
Similarly, triangular drive members (26), (26) are fixed to (25), and both drive members (26), (26) are integrally connected by one lateral rod (28), And the one driving member
The connecting rod (27) is erected from the swing arm of the center side seedling planting mechanism (7) corresponding to (26). With the above structure, the rotor shaft (25) follows the reciprocating swing motion of the swing arm.
It is driven forward and backward at a fixed angle and is configured to feed fertilizer.

Next, the rolling structure will be described. As shown in FIG. 4, the center float (12A) is configured to be capable of rolling around the longitudinal axis (X) of the machine body, and has auxiliary floats (29), (29) integrally operable on both sides.
