Description

[Detailed Description of the Invention] The present invention relates to a paddy field working machine with a fertilizing device, such as a fertilizing rice transplanter.

A fertilizer application device as a paddy field working machine with a fertilizer application device is equipped with a fertilizer supply section such as a fertilizer tank and a fertilizer pump on the main body side, and a fertilizer nozzle is provided on the planting section side that has a planting rod, etc., and this fertilizer supply section A flexible hose is connected between the fertilizing nozzle and the fertilizing nozzle, and the fertilizer from the fertilizer supply section is transferred to the fertilizing nozzle.

In addition, the planting section is connected to the main body of the rice transplanter via an arm so that it can move up and down between a lower planting position and an upper raised position. Therefore, when planting, the arm must be tilted downward. Set the part to the planting position,
When performing turning work, etc., the arm is tilted upward by hydraulic actuation or the like to switch the planting section to the raised position. Generally, when the planting section is placed in the raised position, the fertilization pump in the fertilizer supply section is linked and automatically stops; however, the fertilizer present between the fertilizer supply section and the fertilization nozzle is However, since the hose is flexible, when the planting section is switched to the raised position, there is a problem that the hose is unnecessarily dripped from the fertilization nozzle. At the same time, since the hose is flexible, it bends outward when the planting section moves up and down, causing accidents such as the hose being cut by wheels and the like.

The present invention solves the above-mentioned problems of conventional paddy field working machines with fertilization equipment, suppresses unnecessary dripping of fertilizer from the fertilizing nozzle when the working machine is moved to the raised position, and prevents the vertical movement of the working machine. The purpose of this invention is to provide a paddy field working machine with a fertilization device that does not cause accidents such as cutting of flexible hoses due to wheels or the like.

The present invention achieves the above object by connecting the main body of the traveling part and the work equipment by a lifting arm that tilts downward in the lowered position of the work equipment and upward in the raised position of the work equipment, and is provided on the main body of the traveling part. A substantially middle portion of a flexible hose that connects the fertilizer supply section and a fertilizer nozzle provided on the working machine is connected by a lifting arm that slopes downward at the working position of the working machine and upward at the raised position of the working machine, At the working position of the working machine, point approximately the middle part of the flexible hose that connects the fertilizer supply part provided on the traveling part body and the fertilizing nozzle provided on the working machine downward,
It is supported by the lifting arm so that it can be tilted upward in the raised position of the working machine.

Hereinafter, the present invention will be explained with reference to the embodiment shown in the figure. The figure shows a riding rice transplanter, in which 1 is the main body of the running part of the rice transplanter, wheels 2 and 3 are provided at the front and rear, and wheels 2 and 3 are arranged at the rear of the machine. Lifting arm 4 in the front and back direction
It is configured to tow the planting section 5 as a working machine through the work machine. This planting section 5 is constructed by raising and lowering the lifting arm 4 using hydraulic pressure or the like.
It moves up and down between a planting position where the lifting arm 4 is tilted downward as shown in the figure and a raised position where the lifting arm 4 is tilted upward as shown in FIG.

A driver's seat 6 is provided in the center of the traveling section main body 1, and fertilizer tanks 7, 7 are provided on both left and right sides of the driver's seat 6, respectively. By removing the cap 8, paste-like fertilizer can be poured into the fertilizer tanks 7, 7. Further, fertilizer tanks 7, 7 are provided on the left and right sides to keep the aircraft balanced. The fertilizer tank 7 has protrusions 7a, 7a on the front and rear sides of the upper surface, respectively, so that the fertilizer spilled when the fertilizer is introduced from the upper surface does not flow down from the front and rear sides of the tank. Further, both side surfaces of the fertilizer tank 7 are not located above the seedlings planted by the planting section 5, and at the same time, the inner surface is located above the wheels 3. Therefore, the fertilizer that flows down both sides of the fertilizer tank 7 will not fall directly onto the planted seedlings and cause fertilizer damage, and the fertilizer that falls on the wheels 3 will not be affected by the rotation of the wheels 3. Along with this, it will be buried in the field.

The left and right fertilizer tanks 7, 7 have their bottoms connected to pipes 9.
The pipes 9 are further connected by a plurality of flexible hoses 11 to a plurality of fertilization pumps 10 provided corresponding to the number of planting rows. Flexible hoses 12 are connected to the plurality of fertilization pumps 10.
The indicators 13 are connected to a plurality of indicators 13 provided at positions visible from the driver's seat 6. The above fertilizer tank 7, fertilizer pump 10, indicator 1
3 constitutes a fertilizer supply section.

On the other hand, a float 51 forming the rear planting section 5
A plurality of fertilizing nozzles 52 are provided at positions near the planted seedlings according to the number of rows to be planted. Each tip of the fertilizing nozzle 52 opens into the soil below near the support link of the float 51, and at the same time, a planting rod 53 that moves up and down is located near this.
The tip is facing towards you. This fertilizing nozzle 52 and the above-mentioned indicator 13 are connected by a flexible hose 14. In addition, the plurality of flexible hoses 14 connecting the indicator 13 and the fertilizing nozzle 52 are connected to the front and rear fixing devices along the side surface of the lifting arm 4 over a predetermined length at the positions where the approximately middle portions thereof are divided into left and right parts. 21, 21, the middle part of this flexible hose 14 is
The planting part 5 is in a downward position as the lifting arm 4 is lowered, and the planting part 5 is in a downward position as the lifting arm 4 is raised.
It is designed to face upward at the elevated position.

The fertilizer pump 10 in the fertilizer supply section receives power from a planting section drive shaft 15 extending to the rear of the traveling section main body 1, and is driven via a transmission 16. The rotation of the planting section drive shaft 15 is stopped by the intermittent operation of the planting section clutch, so that the fertilizing pump 10 rotates and stops in synchronization with the planting operation of the planting section 5. Further, the fertilization pump 10 is located below the driver's seat 6, and utilizes a space surrounded by a fender-like cover 17 on the upper side, a chain case 18 for the wheels 3 on the outside, and a frame 19 on the inside. That frame 19
It is designed to be mounted on the side wall of the Therefore, even though it is equipped with multiple fertilization pumps 10, the center of gravity of the machine does not fluctuate and is stable, and there is no need to add a special base member for mounting the pumps, so it can be used with existing rice transplanters. This allows for easy installation. Further, in the above embodiment, since the fertilization pump and the flexible hose piping are protected by the cover 17, chain case 18, etc., it is possible to prevent the flexible hose from breaking due to contact with wheels, etc. You can also do it. Furthermore, by providing the fertilizer pump 10 below the driver's seat 6, the fertilizer tank 7 provided on the side of the driver's seat 6 can be installed.
Not only can the piping between the fertilizer tank 7 and the fertilizer pump 10 be shortened, but also the level difference between the fertilizer tank 7 and the fertilizer pump 10 can be sufficiently removed, so that the fertilizer in the fertilizer tank can be expected to flow reliably to the fertilizer pump.

In addition, the indicator 13 is located at the upper switching point 1.
3a and a lower transparent container 13b. The switching pot 13a is set so that the fertilizer sent from the fertilizer pump 10 through the flexible hose 12 flows into the flexible hose 14 through the transparent container 13b when performing regular planting fertilizer application, but when performing regular planting fertilizer application, If only some of the seedlings are not to be planted, the fertilizer in the flexible hose 12 is switched to the flexible hose 20 by switching the switch 13a for only the rows that are not to be planted, and the fertilizer is transferred to the fertilizer tank 7. It is designed so that it can be circulated. By installing the indicator 13 on the side of the driver's seat 6, the driver can observe the status of the fertilizer passing through the transparent container 13b, and by this observation, it is possible to ensure that the fertilizer is properly delivered to the planting section. You can check whether the

Now, in the above-mentioned fertilizing rice transplanter, the first
When the lifting arm 4 is operated to move the planting part 5 to the raised position as shown in Fig. 6 in order to perform turning from the planting and fertilizing state shown in the figure, the operation of the fertilizing pump 10 is automatically stopped. do. Further, since the intermediate portion of the flexible hose 14 connecting between the indicator 13 of the fertilizer supply section and the fertilization nozzle 52 of the planting section 5 is supported by the lifting arm 4 over a predetermined length, it is directed upward together with the lifting arm 4. In this state, the end portion on the side of the fertilizing nozzle 52 is forcibly curved.
Since the middle part of the flexible hose 14 is in an upward position and the end part is curved in this way, the fertilizer remaining in the flexible hose 14 flows out from the bent part toward the fertilization nozzle 52. As a result, most of the water remains inside the flexible hose 14, and the dripping that occurs in the conventional case is prevented. Further, the intermediate portion of the flexible hose 14 is supported by the lifting arm 4.

As described above, the present invention connects the main body of the traveling part and the work equipment by a lifting arm that tilts downward in the lowered position of the work equipment and upward in the raised position of the work equipment, and is provided on the main body of the traveling part. A substantially middle portion of the flexible hose that connects the fertilizer supply section and the fertilization nozzle provided on the working machine is attached to the lifting arm so that it tilts downward in the working position of the working machine and upward in the raised position of the working machine. Because it is supported, the middle part of the flexible hose that connects the fertilizer supply section and the working machine is
When the lifting arm is raised, the working equipment can be tilted upward in the raised position to prevent the fertilizer in the flexible hose from dripping, and as the lifting arm is lowered, the working equipment can be tilted into a downward facing position. This can facilitate the discharge of fertilizer from the flexible hose.

Moreover, since the intermediate portion of the flexible hose moves integrally with the lifting arm and does not move laterally, it is possible to prevent breakage accidents caused by contact with the wheels or the lifting arm.
