Abstract

PURPOSE:To obtain the subject apparatus capable of performing various operations of seeding, fertilizer application and controlling with one apparatus by spraying a granule or dust branched with a branching plate in a hopper through flow jetting heads with a blower. CONSTITUTION:A sprayer 11 mounted on a mobile machine body is introduced into a field (F) and a granule or dust charged to a hopper is branched with a branching plate at a discharging port of the hopper and sprayed from variable jetting holes of respective flow jetting heads with wind force of a blower. The flow jetting heads can be provided with an oscillating or rotating state to afford various spraying states. Thereby, even coated seeds can be scattered without peeling the coats.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a centrally divided multi-head sowing machine for large plots that enables sowing, fertilization, and pest control work in large plots to be performed with a single device. This relates to fertilization and pest control equipment.

[Conventional technology]

For example, in order to reduce the cost of rice cultivation, it is essential to drastically improve direct seeding systems, seeding, and fertilizer management techniques in large plots.

As shown in Figure 4, when mechanizing seeding, fertilization, and pest control work in a large field F with a short side width of 30 to 50 m, a backpack-type power spreader with a spray head A), a tractor-mounted spray head Various types of spreaders are known, such as an attached power spreader B, a tractor-mounted long-tube multi-head spreader C, a tractor-attached work machine, and a helicopter spreader E.

[Problem to be solved by the invention]

In the above-mentioned A-H spreader 1 work equipment 1 work method, work accuracy is not sufficient, work efficiency 1 work time, fatigue level, etc. need improvement, and most of the
There is also the problem that the machines are dedicated to either fertilization or pest control, and it is a heavy economic burden to have these dedicated machines.

Furthermore, when coated seeds are sown using conventional methods, there are problems such as peeling of the coating and unstable germination and seedling establishment.

It is an object of the present invention to provide a device that solves these problems and allows a variety of tasks to be performed with one device.

[Means to solve the problem]

To achieve the above object, the present invention provides a mobile aircraft with a power source, a hopper, a blower, and a sink multi-mouth jet.

Equipped with a rotating frame, etc., the blower's discharge port is divided into two in the center, and multi-nozzle jets that can be tilted up and down are installed symmetrically, and the granules are distributed from the center of the field to both the left and right sides.

It is possible to spray powders, etc., and the multi-nosed jet can be swung back and forth from side to side or rotated on the rotating frame, allowing two or more types of materials to be sprayed to be sprayed at the same time without mixing, and the amount of spray from both jets automatically adjusted. This feature is characterized in that it is configured to be possible.

[For production] With the above configuration, seeds can be sown in large plots.

To establish a labor-saving work method by extending the flight distance of granule/powder spraying, dividing the field left and right from the center of the field, or by swinging or rotating the field from side to side to expand the spray area of the sprayed agent using the air as a medium. I can do it.

In addition, one unit of equipment can be used for seeding, fertilization, and pest control work.
It is versatile and economical. Furthermore, coated seeds have a low peeling rate and stable germination and seedling establishment.

〔Example〕

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

In FIGS. 1 and 2, reference numeral 1 denotes an entire frame attached to a three-point hitch of a riding tractor or an autonomous traveling unit. This frame 1 supports a rotating frame 3 via an idler wheel 2, 3 has a sinking jet 4. Hopper 7, blower 8. A prime mover 9 and the like that drive the blower 8 are mounted. The sink jet head 4 has a variable discharge jet nozzle 5. It has a wind IJk adjustment 16, etc., and is configured to be tiltable up and down.

Further, a variable branching plate IO is provided in the hopper 7 so that the material to be spread, which has been put into the hopper 7, is equally distributed to the left and right and is supplied to the nozzle head 4. In addition, the rotating frame 8 can be fixed at a predetermined position or rotated back and forth to the left and right at a predetermined angle (
(oscillation), continuous rotation, etc. are possible.

In the dispersion device 11 having such a configuration, as shown in FIG. It is equally divided into two parts by the plate IO and sprayed from the variable nozzle 5 of each sink jet head 4. Incidentally, the amount of spraying and the amount of air blown are adjusted by the air amount adjusting section 6, and the work shown in the lower part of FIG. 3 is performed by fixing the flow jet head 4 and other parts at predetermined positions. The working state when the flow jet head 4 is oscillated is shown in the center of FIG. 3, and the state in which it is rotated 360 degrees is shown in the upper part of FIG.

In this way, the granules or powders branched by the branch plate 10 in the hopper 7 are dispersed through the flow jets 4, 4 by the wind force from the blower 8, so any work such as sowing, fertilization, and pest control can be carried out by a single machine. This can be done using equipment, and even coated seeds can be sprayed without peeling off the coat. Furthermore, the device of the present invention can extend the flight distance by about twice as much as conventional devices, and when used in combination with large-sized seeds (multiple coated seeds), the dispersion becomes more uniform, and germination and seedling establishment are more stable. At the same time, labor saving is achieved.

〔Effect of the invention〕

As explained above, according to the centrally divided multi-head seeding, fertilization, and pest control apparatus for large field fields of the present invention, the following effects can be obtained.

(2) Sewing, fertilizing, and pest control operations can be carried out using only one device, making it versatile and economical.

(2) Moreover, work accuracy 7. Work efficiency is high, and labor savings can be achieved in large plots of fields.

(2) Even with co-coated seeds, there is little peeling of the coat, and uniform dispersion is possible, resulting in stable germination and seedling establishment.
