Description

Harrow installation device with many uses}

TECHNICAL FIELD The present invention relates to a multipurpose harrow fitting, and more particularly, to a multipurpose harrow fitting capable of quickly and easily mounting and removing a harrow and a plow blade, as well as a harrow as well as a plow blade, regardless of the size and type of a rotary. .

The harrow device is a device for spreading large and flat soils smashed by a rotovator when arranging rice fields, and is an essential device for arranging rice fields, especially for seeding.

However, since the harrow device (hereinafter referred to as a harrow) is used to be mounted on a rotary only during flat work, it is usually stored separately from other work or when not used.

Therefore, the worker has to repeat attaching and detaching the harrow of a considerable weight every time the harrowing operation, which requires a considerable time and aerodynamics.

In addition, almost all harrows produced to date are combined with the harrow fittings supporting the harrow fixed to the rotary, so the harrows are incompatible and have a fatal structural weakness that cannot be used when the rotary type or size is changed. will be.

In addition, the conventional harrow mounting tool is to have a structure that can not be used by mounting any other tools other than the harrow has a closed end that greatly falls in terms of utilization.

The present invention can be equipped with a harrow and a plow blade regardless of the size or type of the rotary, but also provides a multi-purpose harrow mounting to enable the mounting and detachment of the harrow and the plow blade quickly and easily without a professional worker. It is to.

The configuration for achieving the object of the present invention as described above in detail by the accompanying drawings as follows.

The present invention is a rotary coupler (100, 100a), the platform (200, 200a) coupled to the rotary coupler rotatably, the hydraulic cylinder 300 is installed in the middle of the platform and the hydraulic cylinder of Harrow coupling sphere 400 is coupled to the end of the rod, and the connecting rod 500 for connecting the tip end of the mounting stage (200, 200a) and the harrow coupling sphere 400.

The rotary coupler (100, 100a) is a U-shaped bolt 130 for coupling to the cylindrical drive shaft case (B) formed on the top of the rotary (A), and the bracket 120 is inserted into the U-shaped bolt is interposed And, to prevent the bracket is rotated is composed of a rotation preventing rod 110 is mounted on the rotary upper surface fixed by the fixing bolt 112.

The anti-rotation member 110 includes the mount 200 by the hydraulic cylinder 300 in a state in which the bracket 120 is coupled to the drive shaft case B by the U-shaped bolt 130 and the nut 140. When raised, the bracket 120 is prevented from rotating together with the mounting table 200, and the bolt coupling hole 111 is screwed to the fixing bolt 112 in the rear of the rotation preventing member 110 When the fixing bolt 112 is tightened, the end of the fixing bolt is fixed while pressing the upper surface of the rotary, so that the fixing position of the bracket 120 can be adjusted at will of the operator.

A shaft hole 122 is formed in the bracket 120 such that the hinge portion 210 of the platform 200 and 200a is rotatably coupled by the shaft 220 and the pin 230.

The pedestals 200 and 200a have a hinge portion 210 formed at one end thereof, and a pipe 250 having a connecting rod coupler 240 formed at the other end thereof. Fixing bolt 241 is screwed to the upper end of the connecting rod coupling port 240, and is fixed to the connecting rod 500 is inserted into the connecting rod coupling port 240 by the fixing bolt 241 is coupled. .

The hydraulic cylinder 300 installed in the middle of the platform 200, 200a has hinges 302, 303 are formed at both ends, one end of the hinge portion 303 has a shaft (C) formed on the upper end of the rotary shaft (C) 330 and the pin 340 is rotatably coupled.

The hinge portion 302 formed at the front end portion, that is, the end of the cylinder rod 301 is rotatably coupled by the shaft 310 and the pin 320 to the bracket 410 formed on the upper portion of the harrow coupling hole 400. Lose.

The harrow coupling sphere 400 connected to the hydraulic cylinder 300 is to be able to mount the harrow (D), the coupling rod 500 is inserted into the coupling rod coupling sphere 420 and formed in the coupling rod coupling A bracket 410 having a shaft hole 411 and a rotation shaft coupling hole 412, a rotation shaft 430 having a shaft hole 431 rotatably coupled to the rotation shaft coupling hole 412, and A bracket 440 having a long hole 441 formed at a lower end of the connecting rod coupler, a shaft 450 passing through the long hole 441 and the shaft hole 431, and a pin 460 for preventing the shaft from being separated. It consists of.

The long hole 441 is to protect the harrow (D) from the impact applied from the front, the shaft 450 is rotated when the harrow coupled to the harrow coupler 400 is flipped back by the shaft 450 The coaxial 430 is lifted up, and the long hole 441 is a long perforated up and down to protect the shaft 450 in consideration of this.

As such, when the hydraulic cylinder 300 is driven by the hydraulic device not shown, the hydraulic cylinder pulls the cylinder rod 301 to lift the harrow coupling sphere 400 upward.

Therefore, when the harrow coupler 400 is lifted up, the connecting rod 500 is inserted into the connecting rod coupler 420 is also lifted, and the connecting rod 500 is connected to the connecting rod coupler 240 of the giant 200 (200a) Since the combined state is interpolated into), eventually the platform 200 (200a) is heard around the drive shaft case (B).

As described above, the distance between the mounting stages 200 and 200a lifted by the hydraulic cylinder 300 can be arbitrarily adjusted by the drive shaft case B and the connecting rod 500, regardless of the structure and size of the rotary. Invented harrow mounting device (1) can be mounted, the present invention, the harrow mounting device (1) can be used for multipurpose because it can selectively install the harrow and the plow blade, all parts are welded without shaft and bolt Since the assembly and disassembly by the pin is possible, it is possible to mount the harrow mounting device 1 of the present invention on a rotary very quickly and easily, even if it is not an expert.

Since the present invention can freely adjust the spacing of the platform, regardless of the structure and size of the rotary, the present invention can be used to mount the harrow mounting, and the present invention, the harrow mounting can be selectively installed to the harrow and the plow blade, so versatile, versatile It can be used to improve efficiency. Especially, it can be assembled and dismantled by shafts, bolts and pins without welding any part, so that anyone can quickly and easily install or detach the harrow and plow blade. To have.
