DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter having, for example, a seedling mounting table and planting claws for continuously performing seedling planting operations.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 5-268815, there has been a technique for mounting a mid-mount type fertilizer on a traveling vehicle.

[0003]

In the prior art, a transfer hose is provided for connecting a fertilizer feeding case outlet on a traveling vehicle to a lateral fertilizer chute on a planting part side. If the length of the transfer hose is too long, the middle part of the hose will bend downward by its own weight, causing the hose to come into contact with the lower rear wheel and the hose to come off from the chute outlet. When the hose is inserted into the middle of the hose to prevent the hose from being bent, the upward bending of the hose is also restricted. Therefore, there is a problem that the hose is easily forcibly bent upward when the planting portion is raised. Also, in a multiple-row planting part such as a six-row planting, the same number of transfer hoses as the number of planting strips are provided on the rear side of the seedling table, and the hose cannot be easily fixed on the rear side of the seedling table. And so on. In addition, as the planting section is moved up and down, the intermediate portion of the transfer hose is folded in the left-right direction to be in a side-down state, and there is a problem that the hose is easily hooked on an adjacent planting depth adjusting lever or the like.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a fertilizer application hopper for storing fertilizer, a multi-row fertilizer feeding case for feeding the fertilizer of the hopper, and an air tank for supplying air to the fertilizer delivery section of the case. And a rice transplanter having a blower provided on one side of the air tank, wherein a fertilizer feeding case is provided with a hose guide body that regulates a bending in a lower surface direction of a transfer hose that connects an outlet of the fertilizer feeding case to a lateral fertilizer chute. A hose guide frame that locks the middle of each multi-transfer hose that connects the outlet of the fertilizer to the side fertilizer chute is provided, and the hose guide frame is arranged on the back side of the seedling table of the planting part. By using the hose guide body and the hose guide frame on the rear side of the seedling mounting table, the transfer hoses for multiple strips can be separated from the rear wheel, etc. and aligned and supported. The hose guide frame can be easily simplified and the maintenance workability can be easily improved, and the hose guide frame is fixed by using the right and left seedling support columns that support the upper end side of the seedling mounting table. It is possible to easily secure the supporting strength and simplify the mounting structure, etc., and to support the upper end portion, the intermediate portion and the lower end portion of the transfer hose at an appropriate position in an appropriate posture by the hose guide body, the hose guide frame and the support member. Further, it is possible to easily prevent the transfer hose to which mud tends to adhere from falling off or coming into contact with other members.

The sensor mounting portion (1) formed integrally with the boot (143)
44), a plug sensor (145) is inserted, and the chute (48) is grounded.
8) When the fertilizer is clogged inside, the sensor (145) is electrically connected to the conductive chute (48) via the fertilizer, and the clogging of the fertilizer is detected. The sensor (14) is attached to the boot (143).
5) to prevent the rust due to the attachment of the fertilizer to the attachment parts, prevent the sensor (145) from deteriorating in performance over time, and easily remove the fertilizer dust from the sensor (145). I have.

As is apparent from the above examples, the present invention provides a fertilizer application hopper (46) for adding fertilizer, and the hopper (4).
Multi-row fertilizer feeding case (4) for sending fertilizer of 6)
7), a rice transplanter having an air tank (51) for supplying air to the fertilizer sending section of the case (47) and a blower (50) provided on one side of the air tank (51). Exit the side line fertilizer chute (4
8) A hose guide body (133) for restricting bending of the transfer hoses (49) and (49) connected to the lower surface in the lower direction is provided, and an outlet of the fertilizer feeding case (47) is connected to the side fertilizer chute (48). A hose guide frame (13) for locking the middle of each multi-transfer hose (49) to be connected.
7) is provided, and the right and left seedling stand supports (13)
6) is provided with a support member (140) for fixing the hose guide frame (137) and mounting a transfer hose (49) near the side-strip fertilization chute (48). By disposing the hose guide frame (137) on the back side of the mounting table (16),
The transfer hoses (49) for multiple strips can be aligned and supported by separating them from the rear wheel (8) by the hose guide body (133) and the hose guide frame (137) on the back side of the seedling mounting table (16). Simplification of the rear side structure of the seedling mounting table (16) and improvement of maintenance workability can be easily achieved, and the right and left seedling supporting columns (136) supporting the upper end side of the seedling mounting table (16) are used. Since the hose guide frame (137) is fixed, it is possible to easily secure the supporting strength of the hose guide frame (137) and to simplify the mounting structure, and to easily perform the hose guide body (133) and the hose guide frame. (137) and the supporting member (140) can support the transfer hose (49) at an appropriate position at an upper end portion, an intermediate portion, and a lower end portion in an appropriate posture,
It is possible to easily prevent the transfer hose (49) to which mud tends to adhere from dropping off or coming into contact with other members.
