Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter with a fertilizer application device.

[0002]

2. Description of the Prior Art As a prior art of this type, as a prior application, Japanese Patent Application No. 57-117654 (Japanese Utility Model Application Laid-Open No. 59-21831).
There is a fertilizer housing part of the fertilizer application on the drive car body, and fertilizer pipes are installed radially from the lower part of the fertilizer housing part toward the fertilization position set in front of the machine of each planting device of the rice transplanter. A rice transplanter with a fertilizer application is disclosed.

[0003]

In the prior application, however, since the fertilizer pipes are provided radially from the lower part of the fertilizer container, the fertilizer pipes are twisted by strain when the rice transplanter is moved up and down. There was a problem that the fertilizer could not flow down in the fertilizer pipe due to interference with the elevating link and damage or bending so that proper fertilization work could not be performed. In order to solve the problem, the prior application has a complicated structure in which the fertilizer pipe is provided with a spiral ridge on the inner surface and the pipe is rotated by a driving device, and the fertilizer pipe moves up and down together with the rice planting device. Rotating and driving the pipe is structurally very complicated and inevitably causes many failures. However, as described in claim 2 of the prior application, the pipe moves up and down, so that it is flexible. However, if the flexible pipe is driven and rotated, it will be consumed and damaged quickly and cannot be put to practical use, and it cannot be put to practical use.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a plurality of moving front and rear wheels 5 and 6 at a rear portion of a driving vehicle body 1 through lifting links 11 and 11 '. Rice transplanting device 7 in which the planting devices 9 are arranged in the left-right direction of the machine body.
In the rice transplanter in which the fertilizers are mounted so as to be able to move up and down, the rice transplanting device 7 is provided with fertilization portions a ... Near the respective planting devices 9 ... The fertilizer storage sections 13 ... Are arranged in the left-right direction of the vehicle body so as to correspond to the substantially front position, and each fertilizer storage section 13 ... From the bottom toward the corresponding fertilization section a. The rice transplanter with a fertilizer application is characterized by having pipes 14 ...

According to the present invention, the rice planting device 7 is provided with the fertilizer portions a ... Near the respective planting devices 9 ... And the rear portion of the drive body 1 has the fertilizer portions a. The fertilizer storage sections 13 ... Are arranged in the left-right direction of the vehicle body so as to correspond to the substantially front position, and each fertilizer storage section 13 ... From the bottom toward the corresponding fertilization section a. Since the pipes 14 are arranged, it is possible to prevent the fertilizer pipes 14 from being twisted due to strain or being unduly interfered with the elevating links 11 and 11 'and being bent even when the rice transplanting device 7 is moved up and down. Also, the fertilizer can be fed from each fertilizer storage unit 13 to each fertilizer pipe 14 without using a complicated structure such as providing a spiral protrusion on the inner surface of the fertilizer pipe and rotating the pipe by a drive device as in the conventional example. … Properly pass through the inside and properly apply each fertilizer a Since fertilizer is guided and fertilized, there are few failures and damages, and good fertilization and rice planting can be performed for many years.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A riding type rice transplanter equipped with a fertilizer application, which is an embodiment of the present invention, will be described in detail with reference to the drawings. Drive car 1
Has a configuration in which a prime mover 3 is mounted on the front part of the machine body 2, a seat 4 is provided on the rear part, and traveling can be performed by traveling wheels 5 and rear wheels 6.

The rice planting device 7 includes a seedling tank 8 and a planting device 9.
…, Float 10… and up / down link 11 ・ 11 '
It is attached to the rear part of the drive vehicle body 1 via the. The front part of the seedling tank 8 is located above the rear wheel 6 in a side view and is arranged so as to be vertically overlapped. Reference numeral 12 denotes a hydraulic device for lifting.

The fertilizer applicator will now be described. The fertilizer container 13 has a seat 4 above the axle of the rear wheel 6 in a side view.
Of the rice planting device 7 and is arranged at a position avoiding the front end elevating trajectory a of the seedling tank 8 of the rice transplanting device 7. One end of the fertilizer pipe 14 ...
, And the other end is communicated with the fertilizer application nozzle 15 to apply fertilizer in the field from the fertilizer part a provided on the float 10 near the front of the planting position of the planting device 9.

When the fertilizer accommodating portion 13 is relatively high in the upward direction, the upper portion may be cut obliquely as shown in FIG. Reference numeral 16 denotes a preliminary seedling mounting table, which is convenient for supplementing the preliminary seedling if it is set slightly higher than the fertilizer housing section 13. Next, the operation will be described.

First, seedlings are supplied to the seedling tank 8 and the spare seedling mounting table 16, and fertilizer is supplied to the fertilizer housing portion 13 to start fertilized rice planting work. Then, with the forward movement of the drive vehicle body 1, the fertilizer in the fertilizer container 13 is applied to the field through the fertilizer pipe 14, the fertilizer nozzle 15, and the fertilizer a ...
The seedlings in the seedling tank 8 are planted in the field after fertilization by the planting device 9.

When the fertilized rice planting work is continued as described above and the drive vehicle body 1 comes to the end of the field and turns, the rice planting device 7 is operated.
Is operated by the hydraulic device 12 to move up and down the links 11.
Is operated via the. In that case, in the rice transplanting device 7, the tip portion of the seedling tank 8 moves up along the trajectory of arrow a in FIG. Not at all.

Further, when the seedling tank 8 is supplemented with the spare seedlings, since the fertilizer accommodating portion 13 is relatively low, the seedlings can be easily supplied from the spare seedling mounting table 16 to the seedling tank 8. And, in particular, the rice planting device 7 has each planting device 9
Is provided near each of the fertilizer receiving portions a ... In the rear part of the drive vehicle body 1, the fertilizer housing portions 13 are arranged in the left-right direction of the vehicle body so as to correspond to the substantially front position of each fertilizing portion a. Since the fertilizer pipes 14 are arranged substantially straight rearward from the bottoms of the fertilizer storage portions 13 to the corresponding fertilizer application portions a ... The pipes 14 ... can be twisted due to strain,
1'is prevented from being unduly interfered with and bent. Still, as in the conventional example, the fertilizer pipe is provided with a spiral ridge on its inner surface to rotate the pipe by a driving device. Even if there is no fertilizer, the fertilizer is properly passed from each fertilizer container 13 through each fertilizer pipe 14 and is properly guided to each fertilizer a. Good fertilization work and rice planting work can be carried out.
