1-2, the traction device comprises a traction beam 4 vertically hinged to the front end of the main beam 1, a cylinder a1 for driving the traction beam 4 to lift is specifically arranged on the main beam 1, a connecting beam 7 assembled with an agricultural machine is horizontally hinged to the end part of the traction beam 4, the connecting beam 7 is also provided with an ear plate 71 with a hinge hole, the ear plate 71 of the connecting beam 7 is connected with the agricultural machine (the agricultural machine is preferably a tractor or other connectable agricultural machine equipment), vertical hinged adjustment of the agricultural machine and the traction beam 4 is realized, and the connecting beam 7 is horizontally hinged to the traction beam 4, so that relative adjustment of the shovel and the agricultural machine in uneven soil after the connection can be realized.

The shovel body 3 is vertically connected to the bottom of the traction beam 4 and is close to one side of the main beam 1, as shown in fig. 1-2, 4 and 6, the height of the traction beam 4 is adjusted by taking the main beam 1 as a base through an oil cylinder a1, and the contact depth of the shovel body 3 and the ground surface is adjusted, so that the leveling effect on the soil can be realized.

In order to realize the leveling operation on the land with different widths, as shown in fig. 2 and 4, two ends of the shovel body 3 are symmetrically provided with adjustable widening shovels 31 which are parallel to the inner surface of the shovel body 3, and preferably, the width of the widening shovels 31 at two sides extending out of the shovel body 3 is adjusted through two oil cylinders a2 arranged at the back side of the shovel body, so as to adjust the operation width of the whole land leveler. And the two sides of the widening shovel 31 are also provided with baffle plates 311 towards the front, so that the soil with the soil higher than the reference position is gathered through the shovel body 3 and the widening shovel 31 and is flattened forwards to a position with lower surface height, and the flattening operation of the whole surface is realized.

In order to adapt to the extending width of the widening shovel 31 at two sides of the shovel body 3, as shown in fig. 2-3, a T-shaped beam 5 is connected between the front wheel 21 and the rear wheel 22 at one side, and the T-shaped beam 5 is transversely and adjustably arranged in the main beam 1 in a penetrating manner. The adjusting mode is preferably that an oil cylinder three a3 connected with the T-shaped beam 5 is arranged at the tail part of the main beam 1, the oil cylinder a3 drives the T-shaped beam 5 at two sides to outwards under the action of adjusting the extending width of the widening shovel 31 at two sides through an oil cylinder two a2, and then the adjustment of the wheel tread at two sides is realized, so that the adjusting mode is suitable for the widening of the shovel body 3, and the more stable support of the shovel body 3 is realized.

Before the ground surface is leveled, the overall flatness has a height drop, and meanwhile, because the overall width formed by the shovel body 3 and the widening shovel 31 at two sides is larger, in order to flexibly adjust the shovel body 3 and the widening shovel 31 according to the ground surface state, as shown in fig. 5, the front end of the T-shaped beam 5 is vertically hinged with a height adjusting beam 51 connected with the front wheel 21.

Since the wheel set assembly 2 supports the whole levelling machine in the ground and travels with the traction of the agricultural machine, the front wheel 21 and the rear wheel 22 can push out ruts in the ground as shown in fig. 7-8, but rather cause unevenness of the ground after levelling, so in order to solve the problem, a rut levelling device is also provided which levels ruts formed by the wheel set assembly 2 synchronously with the travel thereof, as shown in fig. 9-10, the structure comprises a levelling bracket 6 arranged behind the rear wheel 22 and transversely provided with shovel teeth 61, one side of the levelling bracket 6 is preferably connected with the main beam 1 through a hinged connection locked by nuts to adjust the extension of the shovel teeth 61 into the ruts, and the ruts pushed out by the wheels increase the hardness of soil, so that the ruts are projected into the inside of the ruts through the shovel teeth 61 and then plane the soil to the original loose soil shape, thereby improving the surface height of the ruts.

To further flatten the rut, diagonal screeds 62 are provided on both sides of the flattening frame 6, as shown in fig. 9 and 11. As shown in fig. 7 to 8, after the wheels are pressed out of the rut, the soil adjacent to both sides of the rut is gathered and accumulated, so that the soil accumulated on both sides can be leveled into the rut through the inclined leveling plates 62 on both sides during the traveling of the wheel set, thereby solving the problem of uneven ground surface caused by the rut.

The shovel machine may further include an automatic control device, including, for example, a satellite navigation device and a PLC controller (not shown in the figure), where the satellite navigation device is used to measure the elevation coordinates of the earth's surface, and feed back to the PLC controller to adjust each cylinder, so that the shovel body 3 and the widening shovel 31 level the earth with standard earth elevation coordinates, and specifically fill the earth above the earth coordinates to a position below the earth elevation coordinates after gathering the earth above the earth coordinates through the shovel body 3 and the widening shovel 31, so as to achieve a higher leveling effect, achieve an balanced irrigation effect in a later stage, and improve the survival rate of seeds of the plant.

The principle of the application is as follows: the shovel is integrally connected to the agricultural machine through the lug plate 71 of the connecting beam 7, the corresponding actions of all the oil cylinders on the shovel are controlled according to satellite navigation and a PLC, the overall height and the inclination of the shovel body 3 and the widened shovel 31 are adjusted, the extending width of the widened shovel 31 and the wheel tread of the wheel bodies on two sides are adjusted, the land leveling is carried out according to the land elevation coordinates, the soil which is higher than the land coordinates is filled to the position which is lower than the land elevation coordinates after being gathered through the shovel body 3 and the widened shovel 31, and the higher leveling effect is achieved.
