Abstract

PURPOSE:To facilitate loading and unloading a cart by a method in which a rotary bracket is pivotally supported on a top master in a vertically turnable manner, a top link is provided to the upper end of the bracket, and an expandible mechanism is also provided between the lower end of the bracket and the body. CONSTITUTION:In a rotary trench 5, a lower link hitch pin 7 is provided for the front of the body frame 6 and connected with a lower link 3. The intermediate portion of a rotary bracket 9 is pivotally supported in a vertically turnable manner through a pin 10 to the upper end of a top mast 8 upwardly provided projectionally from the frame 6. A top link is also pivotally supported through a pin 11 to the upper end of the bracket 9, and the basal portion of an oil- pressure cylinder 1 is pivotally supported through a pin 13 on the lower end of the top link 2. A large-diameter rotary frame 17 is pivotally supported through a transmission case 16 on the rotary trench 5, and many tilling claws 18 are attached to the peripheral side of the frame 17. The loading capacity can thus be improved, and the attitude in the forward and backward operation can be easily corrected.

The conventionally well-known row trencher has a large number of plowing claws attached to the outer periphery of a large-diameter rotating frame that rotates in the vertical direction, and is attached to the rear of a tractor via a three-point link hitch mechanism for work. There was. [Problems to be Solved by the Invention] By the way, in the above-mentioned conventional 〇-Tari I-wrencher, the rotary frame has a large diameter, so when it is mounted on a tractor,
Even if the rotary trencher was lifted by raising the point linkage mechanism to the maximum extent, its ground clearance would not be very high, and therefore it would not be possible to load it onto the platform of a transport vehicle. Therefore, in order to transport the rotary trencher, a separate device for lifting it is required.

In order to solve the above-mentioned problems, the present invention is a rotary trencher that is attached to the rear of a tractor via a three-point link hitch mechanism, and the top mast of the rotary trencher has a rotating shaft having a predetermined vertical length. The bracket is supported so as to be movable up and down, a 1-tube link is connected to the upper end of this rotating bracket, and a telescoping mechanism is provided between the lower end of the rotating bracket and the main body frame side of the rotary 1 to the wrench. This is a characteristic feature. [Embodiment 1] Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 denotes a riding type tractor. At the rear of this tractor 1, a three-point link hitch mechanism 4 consisting of a first link 2 and a lower link 3 is provided. The wrench 5 is mounted so that it can be moved up and down. The rotary trencher 5 has a lower link hitch pin 7 provided in the front part of the main body frame 6 to be connected to the lower link 3, and is attached to the upper end of a top mass 1-8 that projects upward from the main body frame 6, and is set vertically in a predetermined manner. The middle part of a rotary bracket 9 having a length of 1 is pivotally supported via a pin 10 so as to be vertically movable. The top link 2 is pivotally supported on the upper end of the rotating bracket 9 via a pin 11, and the rotating bracket 9
A base portion of a hydraulic cylinder 12 is pivotally supported via a pin 13 at the lower end portion of the hydraulic cylinder 12 . The tip of the piston rod 12a of the hydraulic cylinder 12 is connected to a pin 15 in a bracket 1-14 provided on the base side (main body frame 6 side) of the piston rods 1-8.
It is pivotally supported through. Further, a large-diameter rotating frame 17 is pivotally supported on the rotary trencher 5 via a transmission case 1G, and a large number of @I claws 18 are attached to the outer periphery of the rotating frame 17. Reference numeral 19 is a cover that covers the outer periphery of the rotary frame 17 and the tilling claws 1B, 20 is a stand, and 21 is a gouge wheel J. Although not shown, power is transmitted to the rotary trencher 5 from the tractor's 1) IO shaft via a transmission shaft. In the rotary trencher 5 having such a configuration, 1
It is attached to the tractor 1 via a three-point hitch 4, is introduced into the ViA field where work is to be done, and is lowered with the stand 20 tilted backwards to rotationally drive the rotary frame 17 and drive the tractor 1. Deep plowing work is performed with the tilling claws 1B while being towed by running <-5. When removing the wrench 5 from the tractor 1 and transporting it to the rotary 1, leave it attached to the 3-point hitch structure 4.
When the point link hitch mechanism 4 is raised to the highest position and the screws 1 to 12a of the hydraulic cylinder 12 are extended,
The rotary trencher 5 rotates upward using the lower link hit pins 7 and 10 as fulcrums to increase its ground clearance, and the loading platform of the transport vehicle is positioned below it, and the piston rod 12a is contracted to rotate the rotary trencher 5. The trencher 5 is lowered onto the loading platform of the transport vehicle, the stand 20 is erected to support it, and the rotary trencher 5 is loaded onto the transport vehicle by disconnecting and disconnecting from the three-point link hitch mechanism 4. and can be easily ylillied. When unloading the rotary trencher 5 from the transport vehicle, either attach it to the tractor 1 via the three-point link hitch mechanism 4, lift the rotary trencher 5, and then move the transport vehicle, or
- All you have to do is move Fukta 1 or drop it on the ground. In addition, the plowing depth during operation of the rotary trencher 5 is as follows:
1iJf of the ground contact height due to the vertical movement of the gauge wheel 21
This plowing depth section VIJ changes the front and rear working posture of the rotary trencher 5, and this changed posture is caused by the screws 1-1 of the hydraulic cylinder 12.
This can be easily corrected by expanding or contracting the connecting rod 12a. Furthermore, 1 liter of rotary trencher 5 is added to 1-rakta 1.
When moving in a state where the tractor is tilted, the piston rod 12a of the hydraulic cylinder 12 is contracted, which causes the lower cleaner 1 to the wrench gear 5 to approach the tractor 1 side. (j is stable and fi
λru. Effects of the Invention As described above, according to the rotary trencher support height adjustment device of the present invention, the rotary bracket is pivotally supported on the top mass 1 so as to be movable up and down, and the upper end of the rotary bracket is A top link is installed at the top of the tank, and a telescoping mechanism such as a hydraulic cylinder is installed between the bottom end and the main body of the rotary trencher. By extending the hydraulic cylinder, the ground clearance of the rotary 1 to the wrench wheel is increased, and loading and unloading onto the transport vehicle is facilitated. In addition, the forward posture of the rotary trencher during work can be easily corrected, and when moving with the rotary trencher attached to the 1-hook, the center of gravity of the machine can be moved forward by contracting the hydraulic cylinder. Tetonfuta running
It is possible to improve the j property.
