A rotary rotor is provided, a rectifying body that can be tightened is provided at a rear position in the traveling direction of the rotary rotor, and a rectifying mechanism for performing a clawing operation of the rectifying body is provided. A ridge trimmer is characterized in that it is provided with a possible rotor transmission mechanism and is provided with a gear shift mechanism capable of varying the ridge tightening capability of the ridge trimming mechanism.

[Action]

The rotation speed of the rotary rotor can be changed by the rotor speed change mechanism, and the tightening ability of the ridge adjusting mechanism can be changed by the speed change mechanism.

The power shaft 9 is rotated through the chain, a chain mechanism 11 is interposed between the power shaft 9 and the input shaft 10 of the rotor speed change mechanism 6, and between the output shaft 12 of the speed change mechanism 6 and the rotary rotor 5. The chain mechanism 13 is interposed and the gear ratio can be varied by operating the operation lever 14.

Reference numeral 15 is a cover member, and the cover member 15 is provided on the machine frame 3 above the rotary rotor 5 and above the ridges.

Reference numeral 16 is a ridged body, and the ridged body 16 is formed in a vertical cross section that matches the upper surface of the ridge and one side surface of the ridge, and the ridge 4 facing surface can gradually approach the ridge 4 surface as it goes backward in the traveling direction. The ridge body 16 is formed in a different shape, in this case, a two-step gradual shape and has a front surface 16a and a rear surface 16b.

18 is a mud body, in this case formed by rubber,
Mounting bolt 16c in the middle of the two-step grading body 16
The sled body 18 is attached to the upper surface of the ridge 4 and one side surface of the ridge.

Reference numeral 19 denotes a ridge adjusting mechanism. In this case, a bearing cylinder 20 is attached to the machine frame 3, a rotary shaft 21 is provided on the bearing cylinder 20, and a square pipe-shaped holding cylinder 22 is fixed to the bearing cylinder 20. Square bar shaped reciprocating body
23 is provided so as to be capable of reciprocating, a crank 24 is provided on the rotary shaft 21, a connecting link 25 is provided between the crank 24 and the lower part of the reciprocating body 23, and a cushioning material 26 such as rubber is provided at the lower end of the reciprocating body 23. The mounting member 27 is connected, and the ridge 16 is mounted on the mounting member 27 so that the process can be adjusted.

Reference numeral 28 denotes a speed change mechanism, in which case a continuously variable transmission is used, a chain mechanism 30 is interposed between the power shaft 9 and an input shaft 29 of the speed change mechanism 28, and an output shaft 31 of the speed change mechanism 28 is provided. A chain mechanism 32 is interposed between the rotary shaft 21 and the rotary shaft 21, and the gear ratio can be varied by operating the operation lever 33.

34a is a ground sled that can move up and down, 34b is a wheel,
It is for supporting the machine casing 3.

Since the first embodiment has the above-mentioned configuration, when the traveling machine body 1 is run along the old ridges and the power take-off shaft 9 is rotated, the rotary rotor 5 crushes the field soil on the old ridges and continuously builds it up. The cover member 10 prevents the mud from scattering above the rotary rotor 5 and to the side of the ridge, and on the other hand, the rotation of the crank 24 of the ridge adjusting mechanism 19 causes the ridged body 16 to reciprocate, and the ridged body 16
When moving forward and backward, the front surface 16a taps the upper surface and one side surface of the ridge 4 through the cushioning member 17, and the rear surface 16b squeezes the cushioning member 17
Further, the upper surface of the ridge 4 and one side surface of the ridge 4 are tapped through the sludge body 18 to perform the ridge adjusting work.

The ridges are tightened well and the ridges can be solid.

Although the ridge adjusting mechanism 19 in the above embodiment is a lever crank mechanism, it can also be applied to one that employs a hydraulic mechanism or the like, and can also be applied to one in which a plurality of ridge adjusting bodies 16 are arranged.

Further, the sludge body 18 is not limited to rubber, but a sponge, a cloth with a blanket attached to the surface thereof, or the like may be used.

The second embodiment of FIG. 4 shows another different structure of the ridge adjusting mechanism 19, that is, in this case, the machine frame 3 is provided with a mounting body 36 by two links 35, and the mounting body 36 is supported by a spring 37 to a supporting frame. 38, the ridge body 16 is attached to the support frame 38, an eccentric disc (not shown) is rotatably mounted in the support frame 38, and the eccentric disc is flexible shaft 39 by the output shaft 31 of the transmission mechanism 28. It is configured so that the ridge fastening work is performed by the vibration caused by the rotation of the eccentric disc.

In the case of the second embodiment, similarly to the first embodiment, the rotation speed of the rotary rotor 5 can be varied by the rotor transmission mechanism 6, and the ridge tightening ability by the ridged body 16 by the transmission mechanism 28, in this case the frequency can be varied.
