Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rice transplanter that is capable of simultaneously planting seedlings, applying fertilizer, and spraying herbicides.

[Conventional technology]

In recent rice transplanters, for example, JP-A-62-
As shown in Publication No. 111605, fertilizers are applied at the same time as seedling planting, or as shown in Japanese Utility Model Publication No. 1988-3788, chemicals such as herbicides are sprayed at the same time as seedling planting to improve work efficiency. The elevated one is used.

[Problem that the invention seeks to solve]

In the conventional example described above, seedling planting and either fertilization or chemical spraying are performed at the same time, but it is expected that further labor savings can be achieved if all of these are performed at the same time.

When configured in this way, both the fertilization device and the chemical dispersion device are equipped with hoppers for accommodating fertilizers or chemicals, so it is practical to easily supply fertilizers and chemicals to these hoppers. is important.

The present invention has been made with attention to these points, and in making it possible to apply fertilizer and spray herbicides at the same time as planting seedlings, it is possible to easily replenish fertilizers and herbicides and improve handling. The purpose is to compose something.

[Means for solving problems]

The characteristic configuration of the present invention is that a fertilization device that supplies fertilizer to the side of the planted seedlings and a herbicide spraying device that sprays herbicide on the field after planting are arranged in a row in the rear of the seedling planting device. In addition, the hoppers of the fertilizer applicator and herbicide sprayer are arranged so that the hopper at the front is higher than the hopper at the rear, and the functions and effects thereof are as follows.

[Effect]

According to the above configuration, fertilizer and herbicide are supplied to each hopper from the rear of the aircraft, and since the rear hopper is lower than the front hopper, the rear hopper gets in the way when the front hopper is supplied. It won't happen.

〔Effect of the invention〕

When constructing a rice transplanter that can save labor by planting seedlings, applying fertilizer, and spraying herbicides at the same time, the hopper of the fertilizer application device and herbicide spraying device are arranged rationally to reduce the amount of fertilizer and herbicide application. It was possible to easily supply the product to the hopper and to have excellent handling properties.

〔Example〕

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

FIG. 1 shows a riding rice transplanter in which a seedling planting device A and a herbicide spraying device 30 are attached to the rear of a riding vehicle body via a link mechanism 13 so as to be movable up and down.

The seedling planting device A includes a seedling planting mechanism 1 in a planting transmission case 9 extending rearward from a planting case 8.
0, and a seedling platform 1 that reciprocates in the lateral direction of the machine in conjunction with the swinging drive of the seedling planting mechanism 10, and a soil leveling float 2 and a field A fertilizer application device 3 is provided to intermittently drop and supply fertilizer.

The seedling planting mechanism 10, as shown in FIG.
A swinging arm 12 is connected to the planting transmission case 9 so as to be swingable, a planting arm 11 is provided at the tip of the swinging arm 12, and a planting claw 19 is provided at the tip of the planting arm 11. The tip of this planting claw 19 rotates cyclically between the take-out port formed at the lower end of the seedling platform 1 and the field, and is placed on the seedling platform 1 as the vehicle body advances. The lower ends of the pine-shaped seedlings are cut off and the seedlings are planted in the field.

As shown in FIGS. 1 and 2, the fertilizer application device 3 includes a laterally long hopper 14 for storing fertilizer, and a plurality of funnel portions 6 spaced apart laterally below the hopper 14. , a feed roll 18 disposed in the case 16 at the lower end of each funnel part 6, a hose 20 provided at the lower end of each case 16 to guide the fertilizer, and a groove cutter 4 attached to the lower end of the hose 20. A chevron-shaped space 7 is formed between the adjacent left and right funnel portions 6, 6 and penetrating in the front-rear direction.

The feed roll 18 is fixed to a drive rotation shaft 15 rotatably supported by the case 16, and as the seedling planting mechanism 10 is driven, the drive rotation shaft 15 is rotated.
The fertilizer is caused to flow down into the case 16 by being rotationally driven. In addition, the hopper 14
As shown in FIG. 1, a sheet with a mesh pattern is attached to the lid 5 of the hopper 14, and the remaining amount of fertilizer in the hopper 14 can be seen from the outside. This prevents sunlight from strongly irradiating the inside of the hopper 14, and prevents the remaining amount detection sensor 21 using a photointerrupter disposed inside the hopper 14 from malfunctioning.

As shown in FIG. 1, a hopper 27 of a herbicide spraying device 30 is arranged between the seedling stand 1 and a hopper 14 for storing fertilizer in the fertilizer application device 3 so as to be located higher than the hopper 14. There is.
This herbicide spraying device 30 includes a hopper 27 for storing the herbicide, a blower 23 connected to the lower part of the hopper 27, and a spraying hose 31 extending rearward from the blower 23. It is composed of A transmission motor (not shown) is provided with a switch that is turned on and off in conjunction with engagement and disengagement of the clutch of the seedling planting device A, and the blower 23 is operated by this transmission motor. , and the blower 23 operates only when the clutch is engaged.

The spraying hose 31 extends rearward through the mountain-shaped space 7, and a spraying port 32 is formed at the rear end of the hose 31. In this embodiment, a powder herbicide is put into the hopper 27, and even if the hose 31 has a gentle slope, the force of the blower 23 allows the herbicide to be sprayed onto the field with good diffusion. Also, like this, the hose 31
By arranging the slope at a gentle angle,
The spraying port 32 can be placed at a relatively high position, and the herbicide can be spread well.

[Another example]

As shown in FIG. 3, only one hopper 27 of the herbicide spraying device 30 is arranged between the seedling stand 1 and the hopper 14 of the fertilizer application device 3, and the hose 31
The chevron-shaped space 7 between the funnel parts 6 and 6 in the central part
The distal end of the hose 31 may be made to be able to swing freely in the horizontal direction, and may be driven back and forth in the lateral direction by an actuator such as a transmission motor. With this configuration, the herbicide can be sprayed over a wide range, and the weight can also be reduced.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
