Description

[Detailed description of the invention] [Industrial application field] The present invention pivots a plurality of planting claws to a planting case that is driven to rotate around a horizontal axis, and rotates the planting case. A seedling planting device is provided in which each planting claw is configured to sequentially take out and plant seedlings from a seedling take-out port of a seedling stand, and an agricultural granular material feeding device is provided above the planting case. Regarding rice transplanters.

[Conventional technology]

There is a desire to improve work efficiency in rice planting work, and a structure that embodies this desire is not to plant one row with one planting claw, but to plant one row with multiple planting claws as described above. Research has begun on a structure that speeds up the planting process, and one example of this structure is disclosed in Japanese Utility Model Application No. 60-55317.

[Problem that the invention attempts to solve]

When the rice transplanter described above is equipped with an agricultural granular material feeding device used as a fertilization device, etc., a sprocket gear is installed on the drive shaft of the planting case, and the sprocket gear and the agricultural granular material feeding device are connected to each other. Some models employ a chain transmission mechanism in which a chain is wound around the input gear, and this structure is relatively large and tends to make the overall structure of the device complex.

Here, the present invention aims at linking the seedling planting device and the agricultural granular material feeding device while avoiding complication of the structure as much as possible.

[Means for solving problems]

The feature of the present invention is that in the above-mentioned rice transplanter, the pivot portion of one of the plurality of planting claws to the planting case and the feeding drive part of the agricultural powder feeding device are mechanically connected to the planting case. The functions and effects are as follows.

[Effect]

Since the planting case can be used as a crank that rotates around the horizontal axis, the mechanical linkage between the planting case and the agricultural granular material feeding device can be constructed relatively easily using a single rod or the like. In addition, the rods and the like can be easily connected to the planting case by simply making some modifications to the support shaft of the planting claw.

[Effect of idea]

As described above, it has become possible to relatively easily construct a linkage structure between an agricultural granule feeding device and a seedling planting device by just making some modifications to the support shaft of the planting claw. A linkage structure advantageous in terms of cost and maintainability was obtained.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Figure 1 shows the overall side view of the fertilization device as a seedling planting device A and an agricultural powder and granule feeding device B. As shown in the figure, a planting case is placed around the horizontal axis P ₁ at the rear end of the planting mechanism 1. 2 is rotatably supported, and two sets of planting claws 3 are provided at both ends of the planting case 2.
A, 3B are provided, and as the planting case 2 rotates, two sets of planting claws 3A, 3B are configured to alternately cut out seedlings from the seedling take-out port 4a of the seedling stand 4 and plant them in the field. has been done. A float 5 for leveling the ground and maintaining its posture is provided at the bottom of the planting mechanism 1, and the seedling planting device A is connected via a link mechanism 6 to a wheeled traveling machine (not shown) so as to be able to rise and fall. There is.

As shown in FIGS. 1 and 2, a ground leveling plate 19 is attached to the front part of the float 5, extending from the upper part of the front end of the float 5 to both left and right sides, and is used for leveling the mud surface on both sides of the float 5 and for leveling the traveling body. It has a mud guard function that prevents mud thrown up by the rear wheels 20 from landing on the upper surface of the float 5.

On the other hand, as shown in Fig. 1, fertilizer application device B
It is composed of a tank 7 for storing fertilizer or seed grains, and a feeding section 8 equipped with a feeding roll (not shown) for intermittently feeding out the powder and granules in the tank 7. It is installed in
The powder and granules coming out of the feeding section 8 are fed from a hose 9 into a groove made in the field by a groove-maker 10, and as shown in FIG. 5 and the planting nails 3A, 3B.

Next, to explain the structure of the planting case 2 in detail, as shown in FIGS. 1 and 3, a drive shaft 11 protrudes from the planting mechanism 1 to the left and right, and the planting case 2 is fixed to this drive shaft 11. At the same time, a cylindrical fixed shaft 13 fixed to the planting mechanism 1 is fitted onto the drive shaft 11, and the planting case 2
A first gear 14 is fixed to the fixed shaft 13 inside the planting case 2.

On the other hand, planting claws 3A and 3B are provided at both ends of the planting case 2.
The gear portion 15a of the cylindrical swing shaft 15 meshes with the first gear 14 via the second gear 16, and the drive shaft 11 is used to drive the planting. The case 2 is rotationally driven, and the two planting claws 3A and 3B pass through the seedling take-out port 4a in the posture shown in FIG. 1 due to the above-mentioned gear engagement action, take out the seedlings, and plant them in the field. be.

More specifically, a cam shaft 12 fixed to the planting case 2 is inserted into the swing shaft 15, and a cam shaft 12 fixed to the planting case 2 is inserted into the swing shaft 15.
A cam mechanism 17 is configured to move the push-out portions 3a and 3b of A and 3B in and out. This cam mechanism 17
When the planting claws 3A, 3B pass through the seedling take-out port 4a, the extruding parts 3a, 3b retract and clamp the seedlings, and when the planting claws 3A, 3B enter the field, the extruding parts 3a, 3b protrudes and pushes out the seedlings.

Next, to describe the linkage structure between the seedling planting device A and the fertilizing device B, as shown in FIG. Feeding drive unit 8a of the formula
As shown in FIGS. 1 and 3, an interlocking link 18 is constructed and connected between the protrusion 12a at the other end of the camshaft 12 of one planting claw 3A and the feeding drive section 8a. There is. With this structure, the rotational movement of the planting case 2 is controlled by the link 1.
8 converts it into a reciprocating motion, which is transmitted to the feeding drive unit 8a, and the powder and granular material is fed out intermittently.
