Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a forced seeding device for a flooded soil direct sowing machine that sows seeds directly into flooded paddy fields without rice planting.

(b) Prior art In conventional direct sowing machines into flooded soil, the paddy is dropped into pre-made grooves by natural fall, and the sowing depth was not stable. In addition, the guide provided on the way down is likely to get clogged, and because the method of making grooves uses its own weight, it is difficult to form grooves in hard fields, and if grooves cannot be formed, the seed rice will be exposed and susceptible to bird damage. Or,
There was a problem with the seedlings causing negative effects such as falling seedlings.

(c) Problems that the invention aims to solve The purpose of this invention is to eliminate such problems with the conventional method. It is a forced embedment type using rotating seeding claws.

(d) Means for solving the problem The purpose of the present invention is as described above, and next we will explain the specific configuration for achieving the purpose.

A paddy receiver 7 is provided at the outlet of the paddy hopper feeding device 3, and the sowing claw 1 has an elliptical trajectory passing through the paddy receiver 7.
A claw guide 5 leading from the paddy receiver 7 to the field area
is constructed along the locus of the seeding claw 1.

(e) Embodiments and operations The purpose and structure of the present invention are as described above. Next, the structure and operations of the embodiments shown in the attached drawings will be explained.

Figure 1 is a side view of the riding-type forced sowing device. Figure 2 is a plan view as well. Figure 3 is a partially sectional side view of the sowing claw and the vicinity of the paddy hopper. Figures 4, 6, and 8 are the paddy receiver and A rear view of the sowing claw gradually acting on the claw guide. Figures 5, 7, and 9 are side sectional views as well. Figure 10 is a side view showing the relationship between the paddy catcher 7, the claw guide 5, and the sowing claw 1. FIG. 11 is a side view of a driven arm that adjusts the trajectory of the sowing claw. FIG. 12 is a diagram showing the rotational trajectory of the seeding claw. FIG. 13 is a diagram showing an embodiment of the forced extrusion claw 9.

The overall configuration of the riding-type forced seeding device will be explained based on FIGS. 1 and 2.

C is a paddy field traveling work vehicle that is also used in the case of a riding rice transplanter. A forced sowing device is attached to a three-point link type work equipment mounting device D provided at the rear of the paddy field working vehicle C. The driving force is transmitted from the paddy field working vehicle C through a universal joint or the like.
Further, the three-point link type work machine mounting device D is moved up and down by a hydraulic system, and the forced seeding device is also moved up and down thereby. 14 is a float, and 10 is a paddy hopper.

Referring to FIG. 3, the paddy hopper 10 stores, as seed paddy, flour-coated paddy whose outer periphery is coated with a film containing an oxygen supply agent, a protective material, fertilizer, medicine, etc.

Therefore, powder-covered paddy is stronger than one with exposed seed paddy, and will not be damaged even by impact with the sowing claw 1. A partition plate 24 is provided in the paddy hopper 10, and the feeding device 3 in this embodiment is of a type that scoops up the paddy accumulated in the feeding portion with a bucket.

The feeding device 3 rotates in the direction of the arrow and drops a fixed amount of paddy onto the receiver 7. Conventionally, the objects fed out from the feeding device 3 would fall as they were, but in the present invention, the objects fed out from the feeding device 3
The flour coated paddy fed out from the paddy is once received on the paddy receiver 7. Then, after receiving it, the sowing claw 1 with a storage recess at the tip is rotated, and the grain-coated paddy is held in the recess and passed through the claw guide at once.
It is carried underground.

The claw guide 5 may be made of an iron plate, but if it is made of a material such as rubber or resin, it will be resilient even if deformed, and there will be no problem even if it interferes with the claw guide.

The role of the claw guide 5 is to cover the left, right, and front sides so that the flour-coated paddy descending while being held by the recess at the tip of the sowing claw does not escape in other directions.

The claw guide 5 has grooves or cracks formed along the rotation locus of the seeding claw 1. If this groove is configured to be closed except when the sowing claw 1 passes through, it will not be clogged with mud or soil and will be even better.

Reference numeral 2 denotes a drive case for the seeding claw 1, which moves in the same way as the planting claw of a rice transplanter, but in the case of the present invention, the rotation of the seeding claw 1 and the rotation of the feeding device 3 are configured to be synchronized. There is. The sowing claws 1 are configured to pass through the paddy receiver 7 immediately after being fed out by the feeding device 3. 13 is a crankshaft, 23 is a crank arm, 12 is a pivot pin, and 4 is a driven arm. By adjusting the position of the pivot shaft 11 of the driven arm 4 with the adjustment screw 25, the rotation locus A of the tip of the seeding claw is slightly changed as shown in A' as shown in FIG. 12. Even if the rotation locus changes from A to A', the structure is such that the point of passing through the pawl guide 5 does not change. This makes it possible to change the seeding depth, etc.

In the embodiment shown in FIG. 13, the push-out claws 9 are configured to forcefully separate the sown paddy from the claws by pushing them out in the soil.

(f) Effects of the invention By forcibly sowing flour coated paddy as described above, this invention can maintain a constant sowing depth, which is the original purpose of a direct sowing machine in flooded soil.

In addition, in terms of workability, the guide pipe is not clogged with flour-coated paddy, and seeds can be reliably sown to the target sowing depth even in hard fields.
