It becomes possible to cultivate.
And at the left and right ends of the tillage rotor, while having the role of improving the straightness of tillage work, it cuts weeds while digging into the tillage and demonstrating the propulsive force at the time of tillage work, and as a guideline for the work boundary A disc-shaped side plate is attached. (For example, see Patent Document 1)

JP 2001-320902 A

The disk-shaped side plate of Patent Document 1 is formed so that the outer circumferential side of the disk is curved toward the body side, and by biting into the soil while pushing the uncultivated soil downward on the outer side surface in the lateral direction of the machine body. This contributes to stable tillage depth and straight running stability.
However, depending on the field condition, the aircraft floats and feels like a reaction caused by the reaction from the uncultivated soil pressed on the outer end surface, so that the biting depth of the tillage nail becomes shallow, and the tillage depth becomes shallow, In some cases, the propulsion of the aircraft was insufficient.

  Then, this invention aims at providing the walk type | mold management machine which can perform tilling work smoothly in all the fields by making it easy to change the form of the said disk-shaped side board according to field conditions. .

  The present invention was created for the purpose of solving these problems in view of the situation as described above, and includes a plurality of tilling claws attached to a tilling shaft and disc-shaped side plates provided at both left and right ends of the tilling shaft. In the walking-type management machine that cultivates the farm field, the disk-shaped side plate is disk-shaped in a side view, and one surface is a dish-shaped disk portion curved in a dish-like shape in the front view of the body, and the center of the plate-shaped disk portion and A hollow cylindrical portion provided at the outer end of the tilling shaft, and the dish-shaped disc portion is inwardly curved with respect to the hollow cylindrical portion, with the circumferential outer end side of the dish-shaped disc portion being curved toward the inside of the machine body. It is characterized in that it can be mounted selectively between a state and an outward state curved toward the outside of the body.

As described above, the present invention provides a walking-type management machine that cultivates a field with a plurality of tilling claws attached to a tilling shaft and disc-like side plates provided on both left and right ends of the tilling shaft. The disk is disc-shaped, and when viewed from the front of the machine body, one surface is composed of a dish-shaped disk part curved in a dish shape and a hollow cylinder part provided at the center of the dish-shaped disk part and at the outer end of the tillage shaft. The disc-shaped disc portion is selected from an inward state in which the outer peripheral side of the disc-shaped disc portion is curved toward the inside of the machine body and an outward state in which the dish-like disk part is curved toward the outside of the machine body. Since the posture state of the disk-shaped disk portion of the disk-shaped side plate can be easily changed according to the field conditions, in the case of field conditions where the tilling depth tends to be shallow, the dish-shaped disk The plate is in a dish-like shape with its outer circumferential end curved outwardly toward the fuselage. The disk unit by easily bite in the field plane, securing a sufficient amount of biting into the field surface of the tilling claws, it is possible to eliminate Asa耘 and propulsion insufficient.
In addition, in the case of deep plowing, the disc-shaped disk portion is in an inward state in which the circumferential outer end side curves toward the inside of the machine body, and importance is attached to the stability of tillage depth and the straightness. You can easily switch to the state.

It is a perspective view of a walk type management machine. It is a side view same as the above. It is a partial rear view same as the above. It is a partial back view same as the above in the state which mounted | wore with the disk shaped side board inward. It is a partial back view same as the above in the state which mounted | wore with the disk shaped side plate facing outward. (A) is a front view of a disk-shaped side plate, (b) is the sectional side view.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 and FIG. 3 show the external appearance of a walking type management machine 1 according to the present invention. A mission case 3 is arranged in a vertical direction on a body frame 2 and a power source is provided above the mission case 3. A certain engine 4 is installed.

A belt transmission (not shown) for transmitting the power of the engine 4 to an input shaft (not shown) of the mission case 3 and a belt transmission on the left side of the mission case 3 and the left side of the engine 4 are covered. A belt cover 5 for wrapping is provided.
A fuel tank 6 is disposed on the engine 4, and a plastic engine cover (bonnet) 7 covering the periphery of the fuel tank 6 is attached.
Although not shown, the fuel outlet hose at the lower part of the fuel tank moves up and down to expand and contract so that it is possible to avoid the inability to start the engine and the inability to move the machine due to running out of fuel. .
This prevents the operator from noticing that the remaining amount of fuel is decreasing, and does not cause fuel replenishment due to out of fuel during work in the field.

Further, at the lower part of the transmission case 3, a tilling shaft 68 driven by the output of the engine 4 extends in the left-right direction of the machine body, and an extending shaft 69 that extends outward in the axial direction of the tilling shaft 68. A tilling claw (rotary claw) 26 is attached one by one.
As a result, two tilling claws 26 are attached to the left and right sides of the transmission case 3 respectively.
Disc-shaped side plates 27 and 27, which will be described later, are attached to the left and right ends of the extension shaft 69, respectively.
In this embodiment, the disk-shaped side plate 27 is attached to the extension shaft 69, but there is no problem even if it is directly attached to the tilling shaft 68.

Further, a hitch 11 is extended from the middle part of the transmission case 3 toward the rear, and a resistance bar 12 protrudes downward from the hitch 11.
A disk-shaped fender 13 is provided below the engine 4 to prevent the mud from jumping up by the tilling claws (rotary claws) 26.

On the other hand, a handle frame 14 protrudes obliquely rearward from the rear portion of the transmission case 3, and left and right handles 15L, 15R extend from the handle frame 14 toward the rear of the machine body.
The left handle 15L is provided with a main clutch lever 16, and the right handle 15R is provided with a reverse clutch lever (not shown).

  Further, the left and right handles 15L and 15R are connected to the handle frame 14 through a vertical adjustment grip 18 so as to be adjustable up and down, and depending on the physique and work contents of the operator who operates the walking type management machine 1, You can adjust it.

By the way, since the walking type management machine 1 described above does not include a traveling wheel, when the main clutch lever 16 is turned on at the same time as the engine 4 is started, the tilling claw (rotary claw) 26 rotates and the machine body becomes the ground surface of the field. Thus, the plowing work by the tilling claw (rotary claw) 26 cannot be performed.
Accordingly, the operator inserts the resistance bar 12 attached to the hitch 11 into the soil by strongly pressing the left and right handles 15L and 15R downward, and gives a certain amount of resistance to the resistance bar 12 to make a plowing work. It aims to stabilize the aircraft posture at the time.
The depth of insertion of the resistance rod 12 into the soil is adjusted by selecting a desired adjustment hole from a plurality of depth adjustment holes (not shown) drilled in the base of the resistance rod 12 and adjusting the depth. This can be done easily by inserting the clevis pin 19 through a hole and a mounting hole (not shown) provided in the boss 11a of the hitch 11.

The disk-like side plates 27 and 27 will be described in detail. As shown in FIG. 6, as shown in FIG. 6, on the left and right ends in the axial direction of the output shaft with the mission case 3 as the center, Disc-shaped side plates 27 and 27 are attached to each other, which serve as a straight line at the time and as a mark for the boundary line at the time of work. In the present embodiment, the disk-shaped side plate 27 has a disk shape made of an iron plate, and has a dish-shaped disk 27a and a hollow cylindrical portion 27b as shown in FIGS. 6 (a) and 6 (b). . After the hollow cylinder portion 27b is fitted into the extension shaft 69, a snap pin (not shown) is inserted into and attached to a pin hole 70 formed at the end of the hollow cylinder portion 27b. Is attached to both ends of the extension shaft 69, and is attached by bolts 27d, which are fasteners, with a reinforcing plate 27c interposed.
With this configuration, the dish-shaped disk part 27a is in a posture with respect to the hollow cylinder part 27b, and is in an inward state in which the outer circumferential side of the dish-shaped disk part 27a curves toward the inside of the machine body, and the outside of the machine body. It is attached so that the posture state can be alternatively changed to the outward state curved toward the direction. Specifically, the bolt 27d which is a fastener is loosened, and the reinforcing plate 27c is first removed, and the disc The direction of the plate-like side plate 27 is selected, and the work is performed by attaching the reinforcing plate 27c and the bolt 27d as a fastener.

Then, when attaching the disc-shaped side plates 27 to both ends of the tilling shaft 68, as shown in FIG. 4, the disc-shaped disk portion 27a of the disc-shaped side plate 27 is replaced with the hollow cylinder portion 27b with respect to the hollow cylinder portion 27b. On the other hand, when the disc-shaped disc portion 27a is mounted in an inward state in which the outer circumferential side of the disc-shaped disc portion 27a is curved toward the inside of the machine body, the dish-shaped disc portion 27a pushes uncultivated soil, thereby stabilizing the tillage depth and the machine body. It is possible to stabilize the straight running. However, depending on the field conditions, the reaction received from the soil pressed by the dish-shaped disk portion 27a makes it difficult for the tilling claw 26 to bite, and the soil remains hard, and no matter how much tillage work is continued, the disk-shaped side plate 27 May not reach deep in the soil of the field and cannot be deeply cultivated, resulting in shallow tillage.
In such a case, as shown in FIG. 5, the disc-shaped disk part 27a of the disk-shaped side plate 27 is attached to the hollow cylinder part 27b in an outward state that curves outwardly of the machine body to perform the tilling work. Therefore, it is possible to plow deeply by acting easily on the dish-shaped disk portion 27a soil, and the disc-shaped side plate bites into the uncultivated soil, and the uncultivated soil is pushed to the center of the fuselage. The nail 26 makes it easier for the uncultivated soil to collapse, and the disk-shaped side plate 27 facing outward from the machine body can bite down and be cultivated.
And this invention can attach the attitude | position state alternatively to the said inward state and outward state with respect to the hollow cylinder part 27b attached to the tilling axis | shaft 68 for the disk shaped disk part 27a of a disk shaped side plate. By doing so, it is possible to respond to different field conditions by changing the direction of mounting the disc-shaped disc part without adjusting the load applied by the operator to the machine body, reducing the operator's work load with a simple configuration Can be made.
