Abstract

PURPOSE:To save the tractor rotation operation by reversing only a travel operation device and a working machine to continue the work without turning the tractor main body when the tractor shuttles in a field. CONSTITUTION:A turn table 9 is provided on the upper end section of a tractor main body 1, and a rotary frame 11 is rotatably provided on this turn table 9 centering a rotary shaft section 12. A rotary shaft is coaxially protruded on the rotary frame 11 from a rotary shaft section 12 and a PTO gear box 7 to constitute a transmission mechanism 14, and the power is transmitted to a PTO15 provided at the lower section of the rotary frame 11. A work fitting device 16 is provided below the PTO15, and a travel operation device 17 is fitted to the rotary frame 11. When the rotary frame 11 is rotated, the travel direction of the tractor is automatically transferred.

In Japan's agricultural fields, where the field plots are small and there are many slopes, the turning operation of the tractor on the headland significantly reduces the work efficiency, and the irregular rotation of the traveling wheels due to turning on the headland. disturb the topsoil by
Leave it in an irregular state with wheel marks left. Furthermore, in sloping fields, the rotation of the machine body causes a shift in the center of gravity, which poses a risk of overturning and the like, which greatly impairs the mechanization of agricultural work on sloping fields. Conventionally, tractors (!I work equipment) used on slopes, etc. include those with only the travel control device (steering device M) reversed, and those that are used for civil engineering work, such as those found in backboards.
There is one that fixes the undercarriage and rotates the entire part other than the undercarriage, including the working parts, around the center of the undercarriage.
In the former case, only the handle is reversed, and the work equipment must be replaced, making it difficult to perform the same type of work in both directions.In the latter case, the weight of the rotating part increases, it does not save energy, and it is difficult to operate on slopes. There was a problem in terms of safety.

To achieve this objective, the present invention provides a tractor body with:
A rotating body equipped with at least a traveling operation device fi#J5 and a work equipment mounting device is provided so as to be rotatable in the horizontal direction, and when the tractor is driven in one direction and turned back at the edge of a field, etc.
The present invention is characterized in that only the rotating body is rotated without turning the tractor main body, and the working machine attached to the travel operating device and the working machine mounting device is reversed to perform work. [Example 1] Hereinafter, the present invention will be described in detail with reference to the drawings. In Fig. 1, reference numeral 1 is a walking type tractor body;
An engine 2 is mounted on the negative side of the main body 1 in the front-rear direction, and a pair of running wheels 3.3 are pivotally supported on both left and right sides of the center portion. The traveling wheels 3, 3 are connected to a chain case 4.one end of which is pivotally connected to the tractor body 1 so as to be rotatable in the vertical direction.
4, and the chain case 4.4 is vertically adjusted by a vertical Ill device alb. As a result, both axles 3.3 have a step so that they can touch the ground. In addition, a transmission 8i1 is provided at the upper center of the tractor body 1.
6 is provided so as to receive power from the engine 2, transmit power from the transmission 6 to the chain case 4.4, and also transmit power to the gear box 7 for P'1'O. It has become. A caster-shaped auxiliary wheel 8 is provided on one side of the lower part of the tractor body 1 in the front direction, and supports the tractor body 1 together with the traveling wheels 3.3. On the other hand, a turntable 9 is provided at the upper end of the tractor body 1, and a plurality of ball bearings 10 are provided on the turntable 9. It is rotatably provided via a rotary plate 13. In the rotating frame 11, a rotating shaft protrudes from the PIO gear box 7 in a regular axis at a rotating shaft portion 12, and a transmission mechanism 14 is configured.
Power take-off device v provided at the bottom of one side of the rotating frame 11!
1 (P'IO>15). Below this power take-off device 15, there is a
116 are provided. A handle 17, which is a traveling operation device, is attached to the rotating frame on the side where the work Ia mounting device 16 is provided. A speed change lever and the like are provided (both not shown), and operating wires 18 extending from the rotating shaft portion 12 are switched and operated by an operating lever 19. The operating wires 18 switch between a position where the rotation of the rotating frame 11 is fixed and a position where the rotation is allowed, and also switch the transmission of the speed change Ia6 to the chain cases 4, 4 between forward and reverse directions, separately from the speed change gear, and control the rotation. When the frame 11 is rotated, the running direction of the tractor body 1 is automatically switched to the opposite direction. A balance weight attachment device 2 is installed on the opposite side of the rotating frame 11 from the handle 17.
0 is provided to maintain balance with the work machine mounted on the work machine mounting device 16. In a tractor with such a configuration, when performing work in the contour line direction in a field with a slope of θ as shown in FIG. A balance weight B is attached, a step is provided on the running wheels 3.3, the machine is run from one side of the field to the other, and a predetermined work is performed using the working machine A. When the machine reaches one end of the vI field, the tractor body 1 travels and works l! Stop driving A, operate the operating lever 19, hold the handle 17, and rotate the rotating frame 1.
Rotate 1 180° and lock. Then, as shown in Fig. 3, the handle 17, the work cell A, and the balance weight B are reversed with respect to the tractor body 1, and the machine is moved from the ridge that has been worked to the next ridge in a switch pack shape to begin the work. Continue. In this case, the level difference between the wheels 3°3 can be left as is, and the rotation (traveling) direction of the running wheels 3°3 is automatically switched, and the machine does not turn on the headland, which improves work efficiency. In addition, since the aircraft does not turn, the headland is not disturbed by the wheels 3.3. Furthermore, even on a slope, there is no risk of the aircraft overturning due to turning, making it safe. Note that there are two types of work equipment A: one that performs work simply by being towed, and one that receives power from the power take-off device 15. In either case, the working direction can be changed simply by rotating the rotating frame 11. The opposite is true, and there is no practical problem. Furthermore, when the running direction of the tractor main body 10 is reversed, the auxiliary wheels 8 automatically turn in the opposite direction to ensure smooth running. Furthermore, the same work can be performed not only on a slope but also on a flat 1iGl field. [Effects of the Invention 1] As explained above, according to the swing-saving tractor of the present invention,
Because it is possible to work on headlands by reversing only the travel control device and the work equipment without having to turn the tractor body, it is energy-saving because the travel wheels do not have to forcefully steer or turn. There is no disturbance of the headland or roughness of the field, and there is no risk of the machine falling over even on a slope, making it safe, allowing stable work to be carried out and improving work efficiency.
