Referring to fig. 1 and 2, the embodiment of the invention provides a portable grader, which mainly comprises a transversely arranged spiral land walking mechanism, a land turning mechanism arranged in front of the land turning mechanism and a rolling mechanism arranged behind the land turning mechanism, wherein the land turning mechanism and the rolling mechanism are integrated, and the front end of the land turning mechanism is provided with a traction engagement part 9.

The spiral land leveling walking mechanism comprises a rotating central shaft 3 which is transversely arranged, walking wheels 4 which are arranged at two ends of the rotating central shaft 3 and a spiral land leveling mechanism 5 which is arranged between the walking wheels 4 on the rotating central shaft 3, and a rolling mechanism and a land turning mechanism are both arranged on the rotating central shaft 3.

Wherein, the traction connecting part 9 at the front end of the plowing mechanism is used for transmitting driving traction force, and in areas where large-scale mechanized operation can not be carried out, the traction connecting part 9 can be connected with people, livestock or portable diesel engines, gasoline engines and the like according to circumstances; of course, if the tractor can be connected with large-scale traction equipment such as a tractor in a wide place such as a plain.

When the soil turning mechanism is used, the whole machine moves forwards under the action of traction force, and in the process, the foremost soil turning mechanism completes soil turning action; the walking wheels 4 are in contact with the ground, and when the whole machine moves forwards, the walking wheels 4 transmit the movement to the spiral land leveling mechanism through the rotating central shaft 3, so that the middle spiral land leveling mechanism rotates to convey the raised part in the land after the land turning mechanism turns the land to a low-lying position, and further the ridge leveling of the land is realized; and the final rolling mechanism rolls and crushes the large and small soil blocks after the spiral land leveling mechanism levels the land, and finally realizes the integral task of leveling the land.

Further, the turning mechanism specifically comprises a U-shaped front hanging frame 6 and a plurality of turning plows 8 arranged on a cross bar of the front hanging frame 6, wherein the opening of the front hanging frame 6 faces backwards, and two ends of the front hanging frame 6 are respectively movably connected to the rotating central shaft 3. The arrangement of the integrated hanging rack simplifies the structure and ensures the overall stability of the structure.

Based on the structure of the soil turning mechanism, the traction connecting part 9 is arranged in the middle of the cross bar of the front hanging frame 6 and is provided with a part extending forwards, and the part extending forwards is provided with a transverse connecting rod 7 for mounting the soil turning plough 8, so that the structure is simple and compact. The top of the plough 8 is provided with a mounting suite for the transverse connecting rod 7 to pass through and be clamped, and the plough is convenient to disassemble.

For example, the towing engagement part 9 is an L-shaped square body, one end of which is arranged on the cross bar of the front hanging rack 6 and the other end of which faces upwards; the transverse link 7 is also a square bar which is arranged at the bottom of the crossbar of the L-shaped towing engagement member 9 and correspondingly the mounting kit at the top of the plough 8 is a square sleeve with an inner diameter adapted to the square bar of the transverse link 7.
