Description

[Detailed description of the invention] This invention relates to a fertilization device for a riding rice transplanter.

Generally, in riding rice transplanters that connect the seedling planting section to the rear of the machine via a coupling mechanism, the weight of the seedling planting section acts on the rear of the machine, which tends to deteriorate the longitudinal balance of the machine. In the case of a device in which a fertilizing device is installed behind the seedling table in the seedling planting section, the weight of the fertilizing device also acts, further deteriorating the longitudinal balance and causing problems such as when the machine heads up. It is something.

In addition, when applying fertilizer to the location where trenches have been created using a trencher, it is necessary to fully consider the effect of muddy water flow on the trenches. In other words, impurities floating in the muddy water flow get caught in the trencher, making it impossible to properly cut the trenches, or the trenches formed by the trencher are broken down by the muddy flow before being covered with soil, causing fertilizer to flow out. This tends to cause problems such as

This idea was made to solve the above-mentioned problems, and it not only improves the front-back balance of the aircraft, but also makes the groove-making action by the groove-making machine appropriate.
It is an object of the present invention to provide a fertilization device for a riding rice transplanter that prevents interference of a movable member of a fertilizer conveying tool to a furrower.

An example of this invention will be explained in detail based on the drawings.
A shows the entire fertilizing rice transplanter, which is composed of a combination of a fertilizer B and a riding rice transplanter C, and the riding rice transplanter C has a seedling planting section at the rear.
Fertilizer B is attached to the top of the planting area.

The riding rice transplanter C is equipped with a prime mover section 2 on the front part of the machine body 1, front and rear wheels 3 and 4 are provided at the front and rear, and a driving section 5 in the center. A seedling planting section D is connected via a mechanism 6.

In the seedling planting section D, a planting claw 9 is rotatably connected to the planting mechanism case 7 via a planting arm 8. A low seedling tray 10 is disposed, and a seedling take-out plate 10-1 with a roughly shaped cross section is provided at the lower end of the seedling tray 10, extending in the lateral direction of the machine. In order to perform the work of planting seedlings in 5 rows, a partition 11 for placing 5 seedlings is provided, and a planting claw 9 is installed.
There are also 5 pieces provided corresponding to the 5-piece planting.

At the lower part of the seedling planting section D, a drive shaft 12 that transmits interlocked power to three planting transmission cases 7 each having five planting claws 9 is horizontally mounted. Below that, 3
The floats 14 are arranged in series.

The float 14 has a wide part 14'' at its front part,
A narrow part 14' is provided behind the wide part 14'', and a notch space 29 is formed on the lateral side of the narrow part 14', and the notch space 29 is located below the lower end of the seedling stand 10. There is.

The groove creator 10 is located in the notch space 29 and inward from the planting claws 9, and is located in the narrow part 1 of the float 14.
It is connected to the side edge of 4'.

A fertilizer application device B is installed in the upper part of the seedling planting section D having such a configuration.
A support rod 15 whose lower end is connected to the planting mechanism case 7 has a fertilization hopper 16 wrapped in the front and back direction at the bottom of the seedling stand 10, and a fertilization hopper 16 at the bottom of the fertilization hopper 16. A chute 18, which serves as a fertilizer conveying device, is placed in a forward-slanting shape at the lower part of the seedling platform 10, and a planting claw is connected to the rear of the seedling take-out plate 10-1. The lower end opening of the float 14 is communicated with the groove maker 19, and the fertilizer is applied into the groove formed by the groove maker 19. A soil covering plate 20 is provided immediately behind the furrower 19, and is configured to cover the soil after fertilization.

A shaft case 21 is installed between each feeding section 17, and a shaft for driving the feeding section is horizontally suspended in the case 21, and a flexible wire 22 is connected to the end of the coaxial shaft. The base end of 22 is interlocked with the output shaft 24 of the central planting mission case 7 via a crank mechanism 23.

In addition, on the side edge of the wide part 14'' of the float 14,
The waterproof plate 25 is extended to the side of the furrower 19 in the narrow part 14' to prevent water from flowing into the furrower 19 side during planting and reducing the fertilization effect. is prevented.

Reference numeral 26 denotes a flexible wire connected to a shaft for driving the feeding section, and the tip of the wire is connected to an alarm device 27, which detects whether fertilizer is being carried out from the feeding section by the operation of the feeding section. Check that. Also, 28 is the planting mission case 7.
It is an interlocking shaft.

The embodiment of this invention is constructed as described above, and the seedling planting section D cuts seedlings from the seedling pine on the seedling platform 10 in the field while the riding rice transplanter C is running. It is something that is planted by
By rotating the planting arm 8, the planting claw 9 is placed on the seedling stand 10.
The planting operation is carried out by cutting the upper seedling pine into seedling blocks, and the groove is formed by the groove creator 19, and fertilizer is applied thereto from the feeding part 17 of the fertilization hopper 16 through the chute 18. However, since the fertilizing hopper 16 is arranged so as to wrap around the lower part of the seedling platform 10 in the longitudinal direction, the fertilizing hopper 10, which is quite heavy when fully loaded with fertilizer, is placed as close to the front of the machine as possible. In particular, the amount of overhang from the fuselage 1 can be reduced, and the longitudinal balance of the fuselage can be improved.

In addition, since the furrower 19 is provided in series with the float 14 in the cutout space 29 below the lower end of the seedling stand 10 and inward from the planting claws 9, it is possible to avoid muddy water. Floating foreign matter is pressed into the soil by the wide part 14'' of the float 14, thereby preventing the foreign matter from getting caught in the trencher 19.

Furthermore, since the muddy water flow flows backward along the outer edge of the wide portion 14'' of the float 14, a strong muddy water flow is less likely to flow into the groove-making position.
This prevents the ditch from being destroyed and washed away by muddy water flow until the ditch is fertilized and covered with soil.

In addition, movable members such as a seedling platform 10 that reciprocates laterally and a planting claw 9 that swings vertically are disposed between the feeding section 17 and the trencher 19. The fertilizer conveying tool 18 is arranged so that the fertilizer conveying tool 18 is downward-sloping from the part 17 to the lower part of the seedling stand 10, passes through the inner position of the planting claw 9 behind the seedling take-out plate 10-1, and reaches the furrower 19. Therefore, interference with movable members is avoided and damage to the fertilizer conveying tool 18 is prevented.

As described in detail above, the present invention connects the seedling planting section D having the seedling platform 10 with a high front height and a low rear height through the connection mechanism 6 to the rear of the machine body 1, and also connects the seedling platform D with the seedling platform
In the fertilizer application device of a riding rice transplanter in which a fertilizer application device B is arranged at the rear of the seedling platform 10, the float 14 is provided with a narrow width below the lower end of the seedling platform 10.
4, a notch space 29 formed on the lateral side is located, and a furrower 19 connected to the float 14 is provided in the notch space 29 at a position inside the planting claw 9. The fertilizing hopper 16 is disposed so as to wrap around the lower part of the seedling platform 10 in the front-rear direction, and furthermore, from the feeding part 17 at the lower part of the fertilizing hopper 16 to the lower position of the seedling platform 10, the fertilizing hopper 16 becomes forward-sloping and forms a lower end of the seedling platform 10. Seedling removal board 10-
Since the fertilizer conveying device 18 is provided at the rear of the hopper 1, which passes through the inner side of the planting claw 9 and reaches the groove maker 19, the fertilization hopper 16, which has a considerable weight when fully loaded with fertilizer, can be moved as much as possible. By placing it closer to the front of the aircraft, it can improve the front-rear balance of the aircraft.

In addition, since the furrower 19 is provided in the notch space 29 and inward from the planting claws 9 so as to be connected to the float 14, foreign objects are less likely to get caught and the furrower 19 is more suitable. This enables reliable fertilization work by preventing fertilizer from flowing out due to the ditch being destroyed by muddy water flow.

In addition, since the fertilizer conveying tool 18 is arranged avoiding movable members between the feeding section 17 and the groove cutting device 19, there is no interference with these movable members, and damage to the fertilizer conveying tool 18 is prevented. It has various effects, such as being able to prevent accidents from occurring.
