Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for tractor work in which various work machines for land preparation, harvesting, growth management, transportation, etc. can be connected to the rear of the tractor in a reliable and stable manner while enduring the reaction of the work. The construction of the machine mounting device will be described in detail as follows with reference to the accompanying drawings showing one embodiment.

The rear of the tractor (1) is used for land preparation, harvesting, and cultivation management.

It connects various working machines (2) for transportation etc.,
Behind the running wheels (3) on both the left and right sides of the tractor (1) in a state that does not interfere with the running rotation of the running wheels (3a) and in a state that the running wheels (3a) remain stationary even when running and rotating? = A reinforcing rod (4) is provided protruding toward the rear of the tractor (1), and all links 151 +61 +71 or some links of the three-point link type coupling mechanism shaft attached to the rear of the tractor (1) are connected to this reinforcing rod (4). 151161 is characterized in that the above-mentioned various working machines (2) are configured to be connected directly or indirectly via the working machine mounting frame (8).

In this embodiment, a cage-shaped connecting frame (9) is attached and fixed to the outer surface of the wheel (3b) of the traveling wheel (3a) of the traveling wheel portion (3) by means of a fixed pole (flO), and this connecting frame (9) A pivot shaft aυ is horizontally protruded in a position concentric with the axle of the running wheel (3a), a bearing (pill unit) is inserted into this pivot shaft 0υ, and this bearing U″lJ is connected to the front end of the reinforcement if (41). The connection is identified by increasing the connection bolt θ at the part, and the running wheel (3a
) Reinforcement H: (4') is provided to protrude rearward in a state that does not interfere with the traveling rotation of the vehicle and in a state where it remains stationary even when traveling and rotating.

In addition, this embodiment illustrates an indirect connection in which the work machine (2) is connected via the work machine mounting frame (8), and this embodiment also shows a three-point link type connection mechanism (left and right of the field). It is also possible to use a single upper link (7) at the bottom and in the middle.

If we talk about the three-point link type connection mechanism (a) here,
This three-point link type connection mechanism (a) is attached to most tractors (IJ), and consists of left and right lower links (5), a hydraulic arm a4 that swings up and down using hydraulic pressure, and an upper link (7).
), h11 pressure arm θ41, lower link (5) and ml
It consists of a connecting link (6) and is attached to attach various working machines (2).

In this way, the rear part of the reinforcing rod (4) is attached to both sides of the work equipment mounting frame (8) connected to the left and right lower links (5) and the ω lower link (6) of the three-point link type connection mechanism (a). fixed connection,
The work equipment mounting frame (8) is fixedly fixed by a support shaft (a5), and the work equipment mounting frame (8) is stably connected to the work equipment mounting frame (8) to attach the work m(2).

Conventional installation of various work machines is done using the three-point link type connection @
They are attached and connected only by a mechanism, but in this case there is no problem at all if the work equipment is not stacked one on top of the other, or if it is a small type that does not protrude more than the width of the tractor, but in recent years, the work equipment If the work involved is highly sophisticated, such as 111, the amount of work is extremely heavy, and the work reaction is also large, and if the work is larger and protrudes beyond the width of the tractor, the above three points will be avoided. It has become difficult to provide stable support with only link-type coupling mechanisms.
This trend will continue to grow in the future, and there is a strong demand for something that can be stably attached to tractors, even large-sized and heavy-duty working machines.

The present invention focuses on such a square, and as described above, from both the left and right sides of the tractor (1), the traveling vehicle M (3a) is rotated while not interfering with the traveling rotation of the traveling vehicle @ (3a). A reinforcing rod (4) is installed to protrude toward the rear while the vehicle remains stationary.
This reinforcing rod (4) and all links (5) (6) of the three-point link type coupling mechanism (a) attached to the rear of the tractor (1)
) (Since the blade or some links (51 (61) are configured to connect the various types of work machines (2) above directly or indirectly through the work machine mounting frame (8), the work machine (2) will also be supported by the left and right reinforcing rods (4),
Since this reinforcing rod (4) protrudes from the traveling wheel portion (3), the load and reaction force at the center of the work implement (2) are absorbed by the three-point linkage mechanism (supported by At the same time, the load and reaction force on both sides are borne by the reinforcing rods (4), which means that each side will share the total load and reaction force, so the M machine (2) is supported stably. 1) Furthermore, it is possible to prevent early damage to the three-point link type coupling machine (a), and furthermore, it is possible to prevent damage to the three-point link type coupling machine (a).
It is extremely effective because it can reliably support even if it protrudes and deviates to either side, and also prevents vibrations during work pA+21.

Moreover, since the structure is simple, just attaching the reinforcing rod (4), it can be implemented easily and at low cost, making it even more effective.

As described above, according to the present invention, it is possible to reliably and stably connect various mulberry working machines for land leveling, harvesting, growth management, and interlocking to the rear of a tractor while withstanding the reaction of the work. +rsr
This provides a tractor work equipment mounting device that has unprecedented effects.
