Abstract

PURPOSE:To improve the workability of the title ditching machine by rotating the scraping member of a pre-processing mechanism along with the running of a running machine so as to remove admixtures to the side when the machine frame of the ditching machine is made to run by means of the running machine, with the ditching bodies and plow member of the machine being maintained at depths from the ground surface. CONSTITUTION:The machine frame 5 of this ditching machine is made to run in a farm (a) by means of a running machine 1, with the ditching bodies 14 and plow member 20 being maintained at depths from the ground surface. Then the ditching bodies 14 are rotated and two ditches are dug into the ground of the farm (a). The plow member 20 scrapes off the excavated soil to the side. When the running machine 1 is run, the scraping member 34 of the pre-processing mechanism 30 is brought into contact with the ground surface so that the member 34 can rotate as the machine 1 runs. The member 34 discharges admixtures G to the side opposite to the excavated soil T, because the member 34 is bent when it comes into contact with the ground surface and jumps when it is separated from the ground surface. Therefore, the ditching work of the ditching bodies 14 can be improved and mixture of the admixtures G with the excavated soil T can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a field trench excavator for forming drainage ditches in fields such as paddy fields.

[Prior art] Conventionally, this type of field trench excavator was developed using the
Publication No. 23, Utility Model Publication No. 42-16323, Utility Model Publication No. 4
As in Publication No. 3-6982, the traveling machine body is provided with a machine frame, and the machine frame is provided with rotating tilling claws, and the tilling claws are configured to plow and crush the field soil and at the same time to blow it away and dig a trench. things are known.

In addition, as another conventional structure, a plow member is provided on the machine frame,
Some are configured to dig trenches with plow members as the traveling machine moves.

In the case of the structure using the above-mentioned tilling claws, the plowing and crushing action is good, but the tilled soil remains due to the splashing action due to the centrifugal force, and the ditch digging marks are not necessarily satisfactory. In this case, the traction force of the traveling machine becomes excessive, and it is necessary to use a large traveling machine that is difficult for ordinary farmers to purchase. Therefore, as shown in Publication of Utility Model Publication No. 59-10214, a groove is installed at the front position of the plow member in the direction of movement. A structure has been proposed in which the cutting bodies are arranged opposite each other to alleviate the trenching resistance caused by the plow member.

[Problems to be Solved by the Invention] However, in the case of the above-mentioned conventional structure, when the grooving body is advanced by the traveling machine, the grooving body cuts a groove in the field, and the plow member is digging the groove, straw waste is left in the field. Scattered foreign matter such as these may impede the furrowing action of the trench cutter, or the excavated material dug laterally by the plow member may ride on the foreign matter and re-enter with the foreign matter. This has the disadvantage that it may fall into the groove.

[Means for Solving the Problems] The present invention aims to solve these inconveniences, and the gist thereof is to provide a traveling machine body, a grooving body capable of cutting grooves in a field, and the grooving body. A plow member is disposed at the rear in the traveling direction of the machine and is capable of scooping up field soil and discharging it to the side; A field trench excavator is characterized in that it is configured to include a pretreatment mechanism provided with a scraping member that causes foreign matter such as straw waste scattered in the field to escape laterally.

[Function] When the traveling machine moves through the machine frame while penetrating the lower part of the groove cutter and the lower part of the plow member into the field, the field surface is cut by the groove cutter, and the soil between the grooves is plowed. It is stiffened by the member and discharged to the side.

At this time, the scraping member of the pre-treatment mechanism rotates as the traveling machine travels, and causes foreign matter such as straw waste scattered at the forward position of the groove cutting body in the traveling direction to escape to the side of the groove cutting body.

1 or an upper through hole is attached to the connecting piece 9, and the main body frame 7 is configured to be retractable upward when not in operation.

The rod 5 is a pair of grooved bodies with several blades 1 on the outer periphery.
4a - 15a are cut out, and a square pipe-shaped support frame part 16 is attached to the main frame part 7 of the machine frame 5 in a substantially forward downward direction,
A mounting member 17 is installed inside the support frame 16 so as to be movable up and down,
The mounting member 17 is provided so as to be movable up and down by the rotation of the handle part by means of a screw mechanism (not shown), and an axle 4 is fixedly protruded from the lower front part of the support frame part 16 so that the right and left ends thereof are downwardly disposed. Grooved bodies 14.B are rotatably mounted on both left and right sides of the 4, with a predetermined spacing therebetween, with the grooves 14 and 14 being opposite to each other.

The powder is a plow member, and in any case, the width of the tip of the plow member is the same as or slightly narrower than the width between the grooved bodies 14 and 6, and the tip of the plow member powder is formed into a tapered scraped portion 2Da. At the same time, the rear part is formed into a discharge part 2Db which is twisted so as to discharge the scraped part to the side.

In this case, the mounting arm 2 is pivotally attached to the rear part of the support frame part 6 provided on the machine frame 5 by means of a mounting pin n, and the weight of the nut is pivoted to the rear end of the main body frame part 7 by means of a pin. A screw rod is screwed onto the body U, and the screw rod 5 is provided so that it can be moved up and down by rotating the handle part.The lower end of the screw rod 6 is pivotally attached to the rear part of the mounting arm 2 with a pin, and the screw rod 5 is attached to the mounting arm 21 with a clearance. It is constructed by attaching component powder.

The part is a stabilizing member, and the front part of the stabilizing member is formed in a sled-shaped front upper part 28a, the central part is formed in a flat part row, and the rear part is formed in a rear upper part 28c, It is fixed to the lower end, disposed between the grooved bodies 14b, and configured to be movable up and down by rotation of the handle 18.

Reference numeral 4 denotes a weight, and a mounting portion 6 is placed near the rear of the main frame portion 7 and is capable of placing the weight 4 on the connection frame portion 6.
It is configured by forming a.

The ring is a pre-processing mechanism. In this case, a rotary shaft is installed horizontally in the connecting frame 6 diagonally to the direction of travel by means of a bearing, a rotary plate is attached to the rotary shaft, and It is constructed by attaching 18 radially self-elastic torsion coil spring-shaped scratching member bowls using bolts Ma/94b.

The part has an elastic tension mechanism, and in this case, a spring catch is attached to the connecting frame part 6 and the support frame part 16, and this spring catch hangs a spring field for pulling up between the gun part and y. It is constructed by hanging.

Since this embodiment has the above-mentioned configuration, when the traveling machine body 1 travels on the machine frame 5 while penetrating the lower part of the groove cutting body 14.j and the lower part of the plow member nod into the field a, the groove cutting body U.15 rotates in the direction of the arrow and cuts two grooves on the field surface a. In this case, the cutting resistance is reduced by the blades 14a and 15a, and the soil between these two grooves cuts into the plow behind them. The material is removed and discharged to the side by the nodding of the part, and as a result, trenching work in the field can be carried out. First, the trench is cut with the trench cutting body 14. Since the pick-up T is discharged to the side, the trenching work resistance can be reduced, the increase in traction force of the traveling machine 1 can be suppressed, and the trenching work can be performed smoothly and efficiently. Since the member winnower is in contact with the field a, it rotates in the direction of the arrow as the traveling machine body I travels, and due to this behavior during this contact, the rotation of the scraping member bowl causes the forward position of the groove cutter U-15 in the direction of travel. Contaminants G such as straw waste scattered in the groove are escaped to the side of the groove cutter 14, 5, in this case, to the opposite side to the discharge position of the excavation upper T, so that the groove cutting action by the groove cutter U, 15 is It is possible to obtain a groove W that can satisfactorily perform the function of a field groove, suppress the excavation of contaminants G onto the surface thereof, and function well as a field groove.

Furthermore, in this case, the stable member row is located between the groove cutting bodies 14 and 15 and comes into contact with the field a, so that the posture of the groove cutting body 5 can be maintained and the depth of groove cutting can be maintained constant, and the digging work can be carried out. The front upper part 28a of the stabilizing member part allows the stabilizing member part to run smoothly, and the stabilizing member part prevents soil from being caught between the groove cutting bodies 14-15 and taken up, and the flat part 28b is It makes sure to contact the field soil surface, and since four weights are placed on the main frame 7, an appropriate load can be applied to the grooving body 14, the rice cake, and the plow member powder, resulting in better grooving. I can work.

When not working, etc., remove the weight 4 from the main frame part 7 and place it on the mounting part 6a, pull out the locking pin 13 from the regular hole 11, and place the main body frame part 7 around the connection axle load of 0. By rotating upward and inserting the locking pin D into the main through hole I2, the main frame portion 7 can be retracted upward, and this is facilitated by the pulling force of the lifting spring of the elastic mechanism. It can be easily pulled up.

In the above embodiment, the grooving body U.15 is a pair of grooving bodies 14.2, but the grooving body 5 may be a machete-shaped grooving blade. In the example, one set is arranged for the pair of groove cutting bodies 14, b and the plow member, but two or more sets may be arranged.

Further, the number of the torsion coil spring-shaped scraping member winches of the pretreatment mechanism section may be selected as appropriate, and the scraping members may have other shapes and structures.

[Effects of the Invention] As described above, when the traveling machine moves the machine frame while penetrating the lower part of the grooving body and the lower part of the plowing member into the field, the grooving body rotates and creates a groove in the field. A cut is made, and the soil between these cut edges is collected and discharged to the side by a plow member behind the cut, and as a result, trenching work can be done in the field. The plow member then discharges this to the side, which reduces the resistance to excavation work, suppresses the increase in the traction force of the traveling machine, and allows for smooth and highly efficient digging work. The scraping member of the mechanism rotates as the traveling machine travels, and foreign objects such as straw that are scattered in the forward position of the groove cutting body in the direction of movement are swept away to the sides of the groove cutting body. Good cutting action is achieved,
A groove that can satisfactorily function as a field groove can be obtained.

As described above, the intended purpose can be fully achieved.
