Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a ridge trimming machine used for creating and repairing ridges.

[Prior Art] Conventionally, this type of ridge trimmer has a structure in which mud is made on the ridges and the mud is applied to the ridges. It is known that the structure is repeatedly struck from above and compacted.

[Problems to be Solved by the Invention] However, in the case of the above-described conventional structure, when grass grows on the ridge, the grass intervenes between the old ridge and the embankment,
Due to the presence of this grass, the degree of adhesion between the old ridge and the embankment is reduced, mutual integrity is reduced, and the embankment is prone to collapse due to the rising of the grass, etc. Therefore, it may be impossible to obtain a robust ridge. Have inconvenience.

[Means for Solving the Problem] The present invention is intended to solve such inconvenience, and referring to the accompanying drawings, the gist of the present invention is to connect a machine frame 2 to a traveling machine body 1 and The frame 2 is provided with a rotary rotor 3 having a plurality of scraping blades 3b for bouncing up and raising soil, and a ridge body 4 capable of clamping the embankment is provided at a rear position of the rotary rotor 3 in the traveling direction. At the front position in the traveling direction of the rotary rotor 3 where the rake is raised, the scratches of the ridge of the scraping blade 3b and the scraping trace of the vertically movable scraping section 25 are overlapped with each other to scrape grass or ridges. In the ridge trimmer, a removable pretreatment mechanism 5 is arranged.

[Operation] While the side surface of the ridge is scraped off by the scraping blade of the rotary rotor for bouncing up and raising the soil, the excavated soil is swung up to the old ridge soil by the rotation of the rotary rotor, and the pretreatment mechanism serves as the pretreatment mechanism. The grass and ridge soil on the ridge surface will be removed in a state where the ridge scraping trace of the scraping blade and the shaving trace of the vertically movable shaving part of the pretreatment mechanism overlap each other.

[Embodiment] FIGS. 1 and 2 show an embodiment of the present invention, in which 3a is a rotor barrel,
3b is a scraping blade, 7 is a three-point type connecting mechanism, 8 and 8'is upper and lower links, 9 is a swing arm, 10 is a lifting link, 11 is a power take-off shaft, 12 is a universal joint, 13 is a main shaft, 14, 14 'is a sprocket, 15 is a chain, 16 is a pivot link, 17, 17' is a sprocket, 18 is an intermediate shaft, 19 is a hydraulic pump, 20 is a hydraulic hose, 21 is a hydraulic cylinder (for the piston action by the hydraulic cylinder. The same applies to the case of reciprocating the crank rod by the crank mechanism.), 22 is a piston rod, 23 is a gear train, 24 is a transmission shaft, and 26 is a rotor cover.

At the front position in the traveling direction of the rotary rotor 3 for bouncing up and raising this soil, the ridge soil scraping mark of the scraping blade 3b and the shaving part 25 which can be moved up and down, in this case, the ridge surface with the scraping trace by the leveling blade overlapping. A pretreatment mechanism 5 capable of removing grass and ridges is provided.

In addition, it is advisable to use a small rotor to remove grass and soil on the upper surface of the ridge.

Further, the pretreatment mechanism 5 may be housed in the front portion of the soil scattering prevention cover 6 of the embankment rotor 3.

Since this embodiment has the above-mentioned structure, when the traveling machine body 1 is run, the scraping blade 3b of the rotary rotor 3 scrapes up the side surface of the ridge a and bounces up to embank it, and the embankment 4 tightens the embankment. The grass and ridges on the ridges located in the forward direction of the embankment position by the rotary rotor 3 that bounces up and raises this soil are scraped by the shaving section 25 of the pretreatment mechanism 5 which can be moved up and down. In other words, the grass that is growing on the ridge surface just before embankment can be removed together with the soil on the upper surface of the ridge, so that the adhesion between the old ridge and the embankment can be improved, which is the old ridge. The integration of the soil and the embankment is enhanced, and the shaving trace by the shaving part 25 of the pretreatment mechanism 5 and the ridge scraping trace by the scraping blade of the rotating rotor are overlapped with each other to form grass and ridges on the ridge surface. Since the soil will be scraped off and the scraping part 25 of the pretreatment mechanism 5 can be moved up and down, the height of the upper surface of the ridge will be increased. It can be moved up and down according to the condition of overgrowth of grass and grass and the condition of ridges, and thus the shaving part 25 can reveal good scavenging marks. Therefore, the adhesion between the old sill and the embankment is further improved. It is possible to obtain robust and durable ridges.

[Advantages of the Invention] As described above, according to the present invention, when the traveling machine body is traveled, the scraping blade of the rotary rotor scrapes up the ridge side surface and flips up by the rotation to embank it, and the embankment compacts and rectifies the embankment. It will be ridged, and the grass and ridges on the ridges located in the forward direction of the embankment position will be scraped off by the shaving part of the pretreatment mechanism by the rotating rotor that bounces and raises this soil, that is, The grass growing on the ridge surface just before embankment can be removed together with the soil on the upper surface of the ridge, so that the adhesion between the old ridge and the embankment can be improved, and the integration between the old ridge and the embankment can be improved. The shaving part of the pretreatment mechanism is raised and the grass and ridges on the ridge surface are removed in a state where the scraped trace of the scraping blade of the rotary rotor and the scraped trace of the pretreatment mechanism overlap. Moreover, since the shaving part of the pretreatment mechanism can be moved up and down, the height of the ridges, the state of grass overgrowth and ridges It can be moved up and down according to the state of, and the excavation part can show a good excavation mark accordingly, so that the adhesion between the old ridge and the embankment can be further improved and it is robust. It is possible to obtain highly durable ridges.

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