Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter equipped with, for example, a seedling mount and a planting claw for continuously performing seedling work.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Laid-Open No. 3-18714, there has been a technique for mounting a mid-mount type fertilizer applicator on a traveling vehicle.

[0003]

In the above-mentioned prior art, the transport hose for connecting the fertilizer feeding case outlet on the traveling vehicle side to the side-row fertilizer chute on the planting section side is provided, but it is necessary for raising and lowering the planting section. If the transport hose is lengthened to a certain length, the middle part of the hose bends downward due to its own weight, the hose may contact the lower rear wheel, and the hose may come off from the chute outlet. If the hose is prevented from being bent by inserting the middle of the hose into the hose, bending of the hose in the upward direction is also limited, so that there is a problem that the hose is easily bent upward when the planting part is raised. Also, in a multi-row planting section such as 6-row planting, the same number of transfer hoses as the number of row to be planted are extended to the rear surface side of the seedling stand, and the hose cannot be easily fixed on the rear surface side of the seedling stand. There was a problem such as. Further, there is a problem that the middle of the transfer hose is bent in the left-right direction due to the raising and lowering of the planting portion and is in a sideways state, so that the hose is easily caught by an adjacent planting depth adjusting lever or the like.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a fertilizer application hopper for storing fertilizer, a multi-row fertilizer feeding case for feeding fertilizer in the hopper, and an air tank for supplying air to the fertilizer feeding portion of the case. In a rice transplanter equipped with a blower provided on one side of the air tank, a hose guide body that restricts bending of at least two lines of the transfer hose that connects the outlet of the fertilizer feeding case to the side-row fertilizer chute is provided. Since the hose guide body prevents downward bending of the transfer hose on the outlet side of the fertilizer feeding case, it is possible to easily prevent the transfer hose from interfering with the lower rear wheel and the like, and the transfer hose for two lines. By also using the hose guide body for the hose guide body, it is possible to arrange the hose guide body with respect to the fertilizer feeding case that configures two sections into one unit. Resulting performed such simplified mounting structure easily, also by free bending direction on the conveying hose, it may prevent the transport hose is forcibly bent at planting section rises.

Further, it is provided with a fertilizer hopper for containing fertilizer, a multi-row fertilizer feeding case for feeding the fertilizer of the hopper, an air tank for supplying air to the fertilizer feeding portion of the case, and a blower provided on one side of the air tank. At rice transplanter,
A single hose guide frame that locks the middle of each transport hose for multiple threads that connects the outlet of the fertilizer feeding case to the side-row fertilizer chute is provided. By arranging the guide frame, it is possible to align and support the multi-conveyance transport hoses on the rear surface side of the seedling mounting table, and also use the hose guide frame for electrical wiring or operation wire tension. As a result, the rear side structure of the seedling mounting table can be simplified and maintenance workability can be easily improved.

Further, it is provided with a fertilizer hopper for putting fertilizer, a multi-fertilizer feeding case for feeding the fertilizer of the hopper, an air tank for feeding air to the fertilizer feeding portion of the case, and a blower provided on one side of the air tank. At rice transplanter,
A hose bundling body is provided for bundling at least two intermediate portions of the transport hose connecting the outlet of the fertilizer feeding case to the side-row fertilizer chute to regulate the bending of each other. The transport hose is connected by the hose binding body. The horizontal bending of the hose can be regulated to prevent it from falling sideways, and it is possible to easily eliminate the problem of the transfer hose being caught by a nearby lever, etc. due to the horizontal fall, and the vertical hose bending of the transfer hose Since it is not limited by the bundle, the transport hose can be smoothly deformed when the planting part is moved up and down, and the transport hose can be abruptly bent and the joint part can be removed.

9) A hose guide body (133) for restricting the downward bending of (49) is provided, and the downward bend of the transfer hose (49) at the outlet side of the fertilizer feeding case (47) is adjusted by the hose guide body (133). 133), it is possible to easily prevent the transfer hose (49) from interfering with the lower rear wheel (8) and the like, and also the transfer hose (49) for two lines.
By also using the hose guide body (133) as the (49), the hose guide body (133) can be arranged with respect to the fertilizer feeding cases (47) and (47) that configure two sections into one unit. The mounting structure of the body (133) can be easily simplified, and the transfer hose (49)
The planting part (1
5) It is possible to prevent the transfer hose (49) from being forcibly bent when rising.

A fertilizer hopper (46) for containing fertilizer
A fertilizer feeding case (47) for multi-rows for feeding fertilizer of the hopper (46), an air tank (51) for supplying air to the fertilizer feeding part of the case (47), and one side of the air tank (51) In the rice transplanter equipped with the blower (50) provided in the above, each conveying hose (49) for multiple rows for connecting the outlet of the fertilizer feeding case (47) to the side row fertilization chute (48) ... The hose guide frame (137) is provided, and the hose guide frame (137) is provided on the rear surface side of the seedling table (16) of the planting part (15).
By arranging the
9) ... can be aligned and supported by the hose guide frame (137) on the rear surface side of the seedling mounting table (16), and the hose guide frame (137) can also be used for electrical wiring or operation wire tension, etc. (16) The back side structure can be simplified and maintenance workability can be easily improved.

A fertilizer hopper (46) for containing fertilizer
A fertilizer feeding case (47) for multi-rows for feeding fertilizer of the hopper (46), an air tank (51) for supplying air to the fertilizer feeding part of the case (47), and one side of the air tank (51) In a rice transplanter equipped with a blower (50) provided in the above, the middle of at least two conveying hoses (49) (49) for connecting the outlet of the fertilizer feeding case (47) to the side-row fertilizing chute (48) is bound. A hose bundle (141) that regulates the bending of each other is provided. By connecting the hose bundle (141), the lateral bending of the transfer hose (49) can be regulated to prevent lateral collapse easily.
Since it is possible to easily eliminate the problem that the transfer hose (49) is caught by a nearby lever or the like due to the sideways falling, and the vertical bending of the transfer hose (49) is not limited by the hose bundle, the planting part When the (15) is moved up and down, the transport hose (49) can be smoothly deformed, and the transport hose (49) can be prevented from being sharply bent or the joint portion coming off.
