Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tilling machine capable of smoothing tilling work by making a cultivated field even.

[0002]

[Prior art]

 Conventionally, as one form of the tiller, a tiller case is attached to the front part of a tiller frame extending in the front-rear direction in an inclined state, and a tiller claw is rotatably attached to the lower part of the case via a rotary shaft. . Then, the traveling machine pulls the tilling implement, and at the same time, the tilling claw of the implement is rotated to perform the tillage in the field.

In addition, the drive mechanism is switched by a switching lever provided on the tilling case to allow forward and reverse rotation of the tilling claw, and when the ridge of the field is high, the soil can be rotated by rotating the claw reversely. I was hoisting it up and doing smooth plowing work.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned plowing work machine has the following problems. That is, when the tilling claw is rotated in the reverse direction and the soil is flipped up, the tilling machine attaches the soil to the upper part of the tilling case, and the attached soil causes the airframe to float up, causing the tiller to cultivate. The depth could not be kept constant, and the cultivated field became uneven, and smooth cultivating work could not be performed. In addition, the soil may make the machine heavier and reduce the tilling force of the tiller.

An object of the present invention is to provide a tilling work machine that solves the above problems.

[0006]

[Means for Solving Problems]

 According to the present invention, a cultivating implement is linked to the rear part of the traveling machine body, and a cultivating shaft is provided at the bottom of the cultivating case provided in the cultivating implement, and the normal cultivating claw or the reverse cultivating claw is attached to the cultivating shaft. (EN) A tilling machine equipped with a rotatably mounted tiller case, characterized in that a soil adhesion preventing body for preventing adhesion of soil splashed by a tilling claw is provided on a lower surface of a base end of a tilling case. Is.

In addition, the present invention provides, as the soil adhesion preventing body, a plowing case provided with a blade body that breaks up the soil splashed by the plowing claw, and the blade body is arranged on the rotation path of the plowing claw. It is characterized by what you have done.

[0008]

[Effect of device]

 According to the present invention, when the tiller claw of the tiller is rotated in the reverse direction to perform the tilling work while raising the soil, when the tiller claws up the soil, the soil is provided on the lower surface of the base end of the tiller case. The soil adhesion preventive body can prevent its adherence. Therefore, by preventing the adhesion of soil, the floating of the airframe can be avoided and the tilling depth can be maintained in a constant state. The flattened state enables smooth cultivating work. Further, by preventing the soil from adhering to the tiller, it is possible to avoid the weight of the machine body and to maintain the tilling force of the tiller.

Further, the blade body of the soil adhesion preventing body can break up the lump of soil that has been flipped up to perform smooth plowing.

【Example】

Hereinafter _, referring to the embodiments of _the present invention, in FIG. 1, reference numeral 1 denotes a walking type traveling machine body. The traveling machine body 1 has a prime mover 3 mounted on a front part of the machine body 2 and A transmission case 4 extending in the vertical direction is interlockingly connected to 3 through an interlocking case, and traveling wheels 5 are rotatably attached to the lower part of the case 4.

A handle 6 extending rearward is attached to the upper part of the mission case 4, and the traveling body 1 is steered by the handle 6. Incidentally, 7 is a travel switching lever, and 8 is a brake lever.

Further, a connecting hitch 9 is provided on the rear side of the mission case 4, and a tilling work machine 10 is connected through the hitch 9 so that the working machine 10 can plow the field. I am sorry.

As shown in FIG. 1, the cultivator 10 is equipped with a cultivating case 12 accommodating a drive mechanism section a at the front part of a cultivating frame 11 extending rearward, and at the bottom of the case 12 left-right The extended tilling shaft 13 is connected, and a plurality of forward rotation or reverse rotation tilling claws 14 are rotatably attached to the same tilling shaft 13. Further, a cultivating cover 11a is attached to the cultivating frame 11, and the cultivating claw 14 is covered with the cover 11a to prevent scattering of soil by the claw 14.

Further, a hitch portion 15 joined to the connecting hitch 9 of the traveling vehicle body 1 is provided on the front side of the cultivating case 12, and the output of the mission case 4 is provided on the input shaft 12a provided on the upper part of the case 12. The power transmission case 16 from the shaft 4a is connected, and the plowing claw 14 is rotated via the drive mechanism part a in the case 12. Reference numeral 11b indicates a tail wheel provided at the rear of the tilling frame 11.

According to the present invention, in the tiller 10 having the above structure, when the tilling claw 14 is rotated in the reverse direction, adhesion of soil scattered to the lower end of the base end of the tiller case 12 is prevented. Will be explained in detail. That is, as shown in FIGS. 2 and 3, a soil adhesion preventing member 18 is attached to the lower surface of the base end of the tilling case 12 to prevent the soil repelled by the tilling claws 14 from being attached via the left and right stays 17. In this embodiment, as the soil adhesion preventing body 18, the blade body 19 is attached to the left and right stays 17 via the bolts 17a with the cutting edge 19a facing downward.

As shown in FIG. 3, the blade body 19 is formed by attaching the left and right side plates 20, 20 to the left and right stays 17 and joining the lower portions thereof, and the cutting edge 19a thereof in the front-back direction. Further, the blade body 19 is extended, and the blade body 19 is disposed on the rotation locus A of the tilling claw 14.

Then, the soil that is lifted up by the tilling claw 14 hits the soil adhesion preventing body 18, prevents the soil from adhering to the tilling case 12, and the prevention body 18 removes the lump of soil from the blade body 19 thereof. It can be broken into small pieces.

Further, FIG. 4 shows a drive mechanism portion a in the cultivating case 12 of the cultivating work machine 10, and the tip end portion of the power transmission case 16 is fitted to the input shaft 12a projecting from the side surface of the cultivating case 12. Then, the power is transmitted to the case 16, the input shaft 12a is rotatably supported in the cultivating case 12, the sprocket 21 is attached to the input shaft 12a, and the sprocket 21 and the lower part of the case 12 are attached. A chain 22 is suspended from the cultivating shaft 13.

Further, as shown in FIG. 1, a reversing input shaft 23 is pivotally supported on the side surface of the tilling case 12 on the locus B when the power transmission case 16 is rotated around its base end. Moreover, the reversing input shaft 23 and the sprockets 24 and 25 provided on the input shaft 12a are meshed with each other.

With this configuration, when the tillage case 12 is driven via the reverse rotation input shaft 23, the input shaft 12a and the tillage shaft 13 rotate in reverse, and the reverse rotation tillage claws attached to the same tillage shaft 13 are rotated. Rotate 14 in reverse.

A spline fitting portion 26 is provided at the tip of each input shaft 12a, 23 so that the tip of the power transmission case 16 can be detachably fitted. When the tip portion of the transmission case 16 is fitted, the input shaft 12a is reversely rotated from the input shaft 23 via the sprockets 24 and 25. Then, in this embodiment, the power transmission case 16 is replaced to switch the forward and reverse rotation of the tilling claw 14.

Reference numeral 27 is a fitting portion at the tip of the power transmission case 16, 28 is a rocket of the power transmission case 16, and 29 is a chain.
