Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a walk-behind rice transplanter with a fertilizer application device.

(B) Conventional Technology Conventionally, as a form of a walk type rice transplanter, there is a so-called four-row-type walk type rice transplanter in which two pieces are installed symmetrically in the body, four pieces in total. is there.

In addition, such a walk-behind rice transplanter usually has a plurality of fertilizer application devices on the machine body at a position corresponding to each seedling planting mechanism, and each fertilizer applicator applies fertilizer before planting a corresponding row of seedlings. Can be given.

(C) Problems to be solved by the invention However, conventionally, in order to attach such four fertilizer applicators to the machine body, two fertilizer applicators are connected to each other in consideration of the positional relationship with the spare seedling stand. Two sets of combined fertilizer application devices are provided to form the combined fertilizer application devices, and the combined fertilizer application devices are respectively arranged on the left and right wheels attached to the left and right sides of the machine body while straddling the same wheels.

Therefore, the fertilizer applicator will be disposed at a considerably high position in the front part of the machine body, which will significantly impair the forward sight of the operator, and the center of gravity of the fertilizer applicator will be located above. , As well as making the aircraft less stable,
There was also a problem in terms of handleability of fertilizer application equipment such as fertilizer replacement work.

An object of the present invention is to provide a walk-behind rice transplanter with a fertilizer application device that can solve the above problems.

(D) Means for Solving the Problems In the present invention, a pair of wheels are attached to both sides of the machine body, two fertilizer applicators are provided between the inner sides of both wheels, and the outer sides of each wheel are respectively provided. In a walk-behind rice transplanter with a fertilizer applicator equipped with one fertilizer applicator, a prime mover is installed in the front of the machine, and a mission is provided behind it, and the left and right sides of the mission are symmetrical. The left and right transmission shaft cases of approximately L shape are connected in series, and the left and right transmission shaft cases are horizontally projected from the mission part to the left and right sides, respectively, and are connected rearward from the tips of the horizontal projection cases. The left and right longitudinal cases are connected to each other, and the left and right planting gear cases are connected to the rear ends of the left and right longitudinal cases. In a U-shape toward the front The bending support frame is erected and fixed, and a horizontal frame extending in the width direction is erected between the upper ends of the support frame to form a gate structure. The invention relates to a walk-behind rice transplanter with a fertilizer application, in which fertilizer applicators for a row are connected and supported.

(E) Action In the rice planting work by the walk type rice transplanter with fertilizer application,
Since the fertilizer application device is disposed between the left and right wheels and on the outside thereof, the position can be remarkably lowered. Therefore, the front field of view of the operator is remarkably improved, and the operator can accurately perform rice planting work while checking the front side. Further, since the center of gravity of the fertilizer application apparatus can be lowered, the traveling stability of the machine body is improved, and the fertilizer application apparatus can be easily filled with fertilizer.

(F) Effect In the present invention, a pair of wheels are attached to both sides of the machine body, two fertilizer applicators are arranged inside the wheels, and one fertilizer applicator is provided outside each fertilizer applicator. Since the device is provided, it is possible to secure a space for the wheels to enter between the fertilizer application devices and lower the mounting position of the fertilizer application device. Therefore, the front view of the worker is improved, and the worker can easily and accurately perform the rice planting work.

Further, since the center of gravity of the fertilizer application device can be lowered, the traveling stability of the machine body is improved, and the fertilizer application work such as exchanging fertilizer can be easily performed.

Further, in the present invention, a rigid-structured gantry frame composed of a support frame that bends in a substantially U-shape and a lateral frame is constructed in the left and right planted gear cases, and the gantry frame is used to
Since the fertilizer applicators for the rows can be connected and supported, a large number of fertilizer applicators can be easily and firmly attached.
