Description

[Detailed description of the invention] The present invention connects a seedling planting device to the rear of the traveling machine, and connects the seedling planting device to the rear of the seedling stand of the seedling planting device, and
A fertilizer tank with a fertilizer feeding mechanism is disposed above the seedling planting claw, and the powdery fertilizer in the fertilizer tank is configured to be supplied to the groove section of the float of the seedling planting device through a hose. This article concerns a rice transplanter with a fertilization device.

In the above-mentioned rice transplanter equipped with a fertilization device, in order to collect the granular fertilizer in the fertilization tank at the end of work, conventionally the granular fertilizer had to be scraped out from the lid opening provided at the top of the fertilization tank, but this was time-consuming. Not only that, but it is not possible to clean and remove the residual powder and granular fertilizer in the feeding roller of the feeding mechanism located at the bottom of the tank and in the hose, and the residual powder and granular fertilizer becomes moist and hardens, making it difficult to clean the powder during the next operation. There was a problem that hindered the transfer of granular fertilizer.

In view of the above-mentioned conventional situation, the purpose of this invention is to make a rational improvement to the fertilization tank mounting structure, to facilitate the recovery of powdery fertilizer in the fertilization tank, and to also facilitate the cleaning of the feeding mechanism and the inside of the hose. The point is to make it possible to do this.

The characteristic configuration of the present invention is that a seedling planting device is connected to the rear of the traveling machine, and a fertilization tank with a fertilizer delivery mechanism is installed at the rear of the seedling stand of the seedling planting device and above the seedling planting claw. A rice transplanter with a fertilization device configured to supply the fertilizer from the fertilization tank to the groove section of the float of the seedling planting device through a hose, a funnel-shaped fitting member is provided at the upper end of the hose. , the lower part of the fertilization tank with the fertilizer delivery mechanism is configured to be able to be fitted and connected to and separated from the fitting member, and further, the fertilization tank is
The structure is such that it can be folded backward together with the fertilizer delivery mechanism by rotating around the transverse axis of the machine body located away from the fitting portion with the fitting member.

In other words, a fertilizer tank with a fertilizer delivery mechanism,
By configuring the fertilizer dispensing mechanism so that it can be connected to and separated from the fitting member at the upper end of the hose, the dispensing roll of the fertilizer dispensing mechanism can be used as the bottom part for preventing leakage of powdery fertilizer. This prevents granular fertilizer from leaking downward when the fertilization tank is tilted backwards, and allows the granular fertilizer to be taken out at once from the opening at the top of the tank, making it easier to collect the granular fertilizer. And we were able to do it quickly.

Moreover, at this time, the interior part of the fertilizer feeding mechanism into the fertilizer application tank and the inside of the fitting member at the upper end of the hose are exposed, so any residual powdery fertilizer in these parts can be easily cleaned and removed. . Therefore, it has been possible to avoid the trouble of transferring powdery fertilizer due to the solidification of residual powdery granular fertilizer, etc., and to always perform good powdery and granular fertilizer transfer.Overall, the fertilization device has excellent powdery and granular fertilizer recovery operability and has fewer transfer troubles. We have now been able to offer a rice transplanter with a built-in rice transplanter.

Furthermore, since the fertilization tank is configured to be rotatable around the horizontal axis of the machine at a position away from the fitting connection point with the fitting member at the upper end of the hose, fertilization can be applied as the fertilization tank rotates. There is an advantage that the lower end of the tank and the fitting member at the upper end of the hose are relatively far apart from each other, making it easier to clean the feeding mechanism and the hose.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

As shown in Fig. 1, a pair of left and right propulsion rear wheels 1
and a pair of left and right propulsion front wheels 2 for steering operation.
A front driving section 4 and a boarding operation section 5 are installed on the body frame 3, which is equipped with a front driving section 4 and a boarding operation section 5, as well as an inclined seedling loading table 6 that moves back and forth horizontally with a constant stroke, and a vertical circulation operation from which the inclined seedling loading table 6 sequentially feeds one seedling. A seedling planting device 9 equipped with various devices such as a plurality of seedling planting claws 7 for taking out the seedlings and planting them on the mud surface, and a plurality of soil leveling floats 8 arranged side by side in the left and right direction of the machine is installed at the rear of the machine frame 3. The system is further equipped with a fertilization device 11 which is connected to the device via a link mechanism 10 so as to be freely operable to raise and lower the drive, and which embeds powdered and granular fertilizer into the seedling planting area by each seedling planting claw 7 as the seedlings are planted. This constitutes a riding-type rice transplanter that sequentially plants multiple rows of seedlings while applying fertilizer as the machine travels.

As shown in FIGS. 1 and 2, the fertilizer application device 11 includes a support frame 12 connected to the front part of the fuselage frame 3, and a granular fertilizer storage located above the driver's seat 5a. A main tank 13 for fertilization is attached to the support frame 12, and an auxiliary tank 14 as a fertilization tank is attached to the seedling planting device 9. The main tank 13 and the auxiliary tank 14 are connected to each other by a flexible hose 15, so that the powdered fertilizer in the main tank 13 is transferred to the auxiliary tank 14 through the flexible hose. In addition to being able to supply water to both tanks 1 by raising the seedling planting device 9,
The flexible hose 15
The structure is such that powdery fertilizer can be supplied without any problem while allowing for elastic deformation.

In addition, the auxiliary tank 14 of this fertilizer application device 11
The machine is integrally equipped with a fertilizer dispensing mechanism 17 at its lower part that can dispense a predetermined amount of powdered fertilizer inside the machine. A plurality of trenching sections 16 for forming grooves in the mud surface near the planting site and embedding fertilizer in the grooves are integrally formed at the bottom of each soil leveling float 8. The discharge ports of a plurality of fertilizer delivery mechanisms 17 provided at the lower part of the auxiliary tank 14 are connected to each other via hoses 18 separately.

In this way, the fertilizer application device 11 transfers the powdery fertilizer in the main tank 13 to the auxiliary tank 10 equipped with the fertilizer delivery mechanism 17 by dropping the powdered fertilizer in the hose 15 by its own weight.
At the same time, a predetermined amount of fertilizer is supplied from the fertilizer delivery mechanism 17 at the bottom of the auxiliary tank 14 to each groove section 16, and a predetermined amount of fertilizer is applied to each row as the machine travels. There is.

The feeding mechanism 17 has a fertilizer feeding roll 20 installed in the lower part of the auxiliary tank 14, which has fertilizer receiving grooves 19 arranged in parallel on the outer periphery so as to be rotatable around the transverse axis of the machine. An arm 23 integrally connected to the support shaft 22 of the swing arm 21 so as to swing together with the circulation swing arm 21.
and a rotating shaft 24 protruding from the lower side wall of the auxiliary tank 14, so that the rotating shaft 24 is intermittently rotated at a fixed angle in a fixed direction by one reciprocating swing of the arm 23 accompanying one cycle of the planting claw 7. Link mechanism 2
5 and a ratchet-type one-way clutch 26, and by the intermittent rotational action of the feeding roll 20, which is rotationally driven in accordance with the rotation of the rotating shaft 24 accompanying the planting operation of the seedling planting claw 7. , so as to sequentially supply a predetermined amount of granular fertilizer to each groove section 16.

Next, the attachment structure of the auxiliary tank 14 to the seedling planting device 9 will be described in detail.

A support frame 29 that supports each auxiliary tank 14 is attached to a support frame 28 connected to a planting mission case 27 as a support for the planting device 9 so as to be swingable around the horizontal axis Q of the machine, and a hose The connecting funnel (fitting member) 30 connected to the upper end side of the auxiliary tank 14 is pivotally connected to the support frame 28 in a state where it is fitted and connected to the outlet of each feeding mechanism 17 at the bottom of the auxiliary tank 14. , feeding mechanism 17
The attached auxiliary tanks 14 are configured to be able to be freely tilted and swung toward the rear of the machine body around the horizontal axis Q, integrally with the feeding mechanism 17.

In other words, at the end of work, etc., the auxiliary tank 1
To collect the fertilizer in step 4, the upper lid 14 of the auxiliary tank 14 is attached with the hose 15 for connecting to the main tank 13.
