Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mounting structure for mounting a fertilizer application to a tiller connected to a tractor.

[Conventional technology]

BACKGROUND ART When performing cultivating work with a rotary of a cultivator connected to a tractor, fertilizer is sprayed in front of the rotary to mix the cultivated soil with the fertilizer.

Conventionally, a fertilizer application device for spraying fertilizer is attached to the rear part of a tractor, and the fertilizer discharged from the fertilizer application device is guided by a fertilizer application tube to be sprayed on the ground.

[Problems to be solved by the device]

By the way, when attaching a fertilizer application to a tractor, the structure of the tractor varies depending on the manufacturer, so it is necessary to manufacture a dedicated mounting structure according to the model of the tractor. ) There is a problem that improvement is required.

Therefore, this invention focuses on the fact that the frame pipe is always located on the upper part of the tiller even if the manufacturer is different, and by using this frame pipe, the fertilizer applying device is attached. An object of the present invention is to provide a mounting structure that allows a fertilizer application device to be arranged behind a tractor with a single structure.

[Means for Solving the Problems]

In order to solve the above problems, the present invention is to mount a square tube parallel to the frame pipe on a base plate fixed with U bolts on both sides of the frame pipe in the tiller, and insert the square tubes into the square tubes to position them. A structure in which a pillar is erected on the upper surface of the end of the two-sided supporting rod that is fixed so that it can be freely adjusted, and the fertilizer hopper mounting rod is fixed to the horizontal arm that is attached to the upper part of both pillars so that the vertical position can be adjusted freely. Is adopted.

[Action]

Base plates are attached to both sides of the frame pipe in the cultivator, the supporting rods are inserted into the square tubes provided on the plates, and the fertilizer hopper mounting rods are attached to the upper portions of the columns standing on both the supporting rods via horizontal arms. The fertilizer applicator can be mounted on the cultivator, and the base plate can be fixed to the frame pipe with U bolts, and the support rod to the square tube can be freely adjusted. The mounting state corresponding to can be selected.

The columns 16 and 16 are fixed so as to be erected on the upper surfaces of the ends of the support rods 15 and 15 that are close to each other, and the columns 16 and 16 are attached to the upper pipe 22 at the upper end of a vertically standing lower pipe 21. The upper and lower pipes 21 and 22 are fixed by bolts 23 screwed on the upper portion of the lower pipe 21, and the upper pipes 22 and 22 on both sides are bent in the middle, The upper half portions are formed so as to approach each other and stand upright.

The horizontal arm 17 is, as shown in FIG. 3, a pair of vertical pipes 24, 24 externally fitted onto the upper pipes 22, 22 of the columns 16, 16 so as to be vertically movable, and both vertical pipes 24, 24. Tractor 1 with horizontal pipe 25 connecting both and vertical pipes 24, 24
Formed with horizontal pipes 26, 26 fixed to the side facing the side,
By tightening bolts 27, 27 screwed on both vertical pipes 24, 24, the upper pipes 22, 22 can be fixed at arbitrary positions above and below.

The mounting rod 8 in the fertilizer applicator 7 has pipes 28, 28 fixed to both sides of the central portion of the upper surface, fitted onto the horizontal pipes 26, 26,
It is fixed with bolts 29 so that the position of the tractor 1 can be adjusted in the front-rear direction.

In addition, as shown in FIG. 1, the pillar 16 standing upright on the frame pipe 3 has a proper position on the tractor 1 and a turnbuckle 30.
The upright posture of the support column 16 is always substantially vertical regardless of the rising or falling positions of the rotary.
