Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 The present embodiment provides a land leveler, including a tiller cavity 1 and a connecting plate 5. A crossbeam 2 is fixedly installed on one side of the tiller cavity 1. A spiral drum 3 is movably connected between the tiller cavity 1 and the crossbeam 2. The spiral drum 3 is used to drop fine soil in the movable gap between the rotating parts. The spiral structure rolls and transmits larger stones or grass roots floating on the surface. A rivet 6 is fixedly arranged inside the connecting plate 5. A rake hook 4 is fixedly connected to the side of the rivet 6. The standard arrangement of the rake hook 4 is used to rake the ground and turn the soil on the ground. An upper arc plate 7 is fixedly connected to the inner surface of the tiller cavity 1. Large lumps of soil or stones are accumulated in the inner cavity of the tiller cavity 1. Because there is a sudden overflow during the movement, they are discharged along the guiding direction of the upper arc plate 7. A discharge chute 8 is fixedly connected to the side of the crossbeam 2. The soil is turned over by the rake hook 4 so that larger objects such as larger clods of soil or stones are collected in the position of the tiller chamber 1, and after overflowing, they fall to the position of the spiral drum 3, crush the larger clods of soil, and then fall back to the ground through the gaps. Other larger shapes such as stones or branches are transferred to the next position under the spiral transmission of the spiral drum 3, thereby screening out larger impurities except soil; a bracket 18 is fixedly connected to one side of the tiller chamber 1, and a main shaft 19 is fixedly connected to the end face of the bracket 18, and a wheel 20 is rotatably connected to the end face of the main shaft 19; by setting the rotation of the wheel 20, the tiller chamber 1 is moved at a certain height, which is conducive to the rake hook 4 to rake the soil to the ground at a horizontal height, and the turning process of the rake hook 4 does not have severe position shaking.

[0021] The inner surface of the cross beam 2 is fixedly connected with a fixing plate 9, the inner surface of the fixing plate 9 is rotatably connected with the spiral drum 3, the two sides of the cross beam 2 are fixedly connected with an axle seat 12, the inner surface of the axle seat 12 is rotatably connected with a bearing 11, the end surface of the tiller cavity 1 is fixedly connected to the input end of the spiral drum 3, and each spiral drum 3 is fixedly connected by setting a rotatable connection between the bearing 11 and the axle seat 12, and the fixing plate 9 is set to fix the gap position between the spiral drums 3 of the array, so as to achieve the structural stability of the spiral transmission of the spiral drum 3, and the stones overflow from the upper surface position of the fixing plate 9;

[0022] The side of the crossbeam 2 is rotatably connected to a driven gear 10, the outer surface of the driven gear 10 is meshedly connected to a crawler 16, the inner surface of the crawler 16 is meshedly connected to a driving gear 15, the side of the driving gear 15 is rotatably connected to the side of the crossbeam 2, and the side of the crawler 16 is fixedly connected to a conveyor belt 17. By setting the conveyor belt 17 to move synchronously with the position of the crawler belt 16, larger impurities such as stones accumulated on the conveyor belt 17 are discharged, and because the driven gear 10 and the driving gear 15 are set to drive the crawler 16 to do periodic movement, continuous transmission of fallen stones is achieved.

[0023] See also Figure 1 and Figure 2 The present embodiment provides a land leveler, a triangular hinge 21 is fixedly installed on one side of the cross beam 2, a hinge interface is provided on the end face of the triangular hinge 21, and the triangular hinge 21 is located in front of the rake hook 4; the triangular hinge 21 is provided to connect to the drive of agricultural machinery such as a tractor, and the pulling force is fixedly connected to one end of the two cross beams 2 respectively, so that the pulling force is transmitted more evenly, and the rake hook 4 is in the process of turning over the soil and arranging the overflowed fine soil until the wheel 20 rolls.

[0024] See also Figure 3 and Figure 4 The present embodiment provides a land leveler, the upper end of the fixed plate 9 is fixedly connected with a lower arc plate 14, the output end of the motor 13 is fixedly connected with the side of the spiral drum 3, and the lower arc plate 14 is provided to protect the stones or soil transmitted by the spiral from falling to other positions. The spiral drum 3 is tilted downward in the tiller cavity 1 to achieve a stable transmission movement direction.

[0025] Working principle:

[0026] Step 1: Before using the equipment, first check whether the rake hook 4 provided at the lower part of the tiller cavity 1 is broken or damaged, and then drive the motor 13 to see whether the spiral drum 3 can rotate normally. The internal position of the tiller cavity 1 should not have a lot of accumulated silt stuck inside. You can use a crowbar or other objects to knock or remove large pieces of soil to see if it is conducive to the upper arc plate 7 to guide and throw out the turned soil;

[0027] Step 2: After the hinge interface at the position of the triangular hinge frame 21 is connected to the tractor or other agricultural machinery, the equipment can be pulled to move, the wheel 20 rotates on the ground to drive the displacement, the rake hook 4 deeply scrapes the ground to loosen the soil, and the turned soil falls into the inner cavity of the tiller cavity 1. The soil is turned and overflowed and discharged to the upper surface of the spiral drum 3 along the direction of the upper arc plate 7;

[0028] Step 3: With the rotation of the spiral drum 3 and the spiral transmission of the spiral drum 3 itself, the soil as small particles leaks through the gaps between the spiral blades, and large and small stones or lighter grass roots continue to move forward on the spiral drum 3 until the stones, grass roots and other debris are transmitted to the position of the conveyor belt 17;

[0029] Step 4: The stones or grass roots screened out from the soil are left on the conveyor belt 17, and the driving gear 15 rotates to drive the driven gear 10 to move, so that the crawler belt 16 moves periodically during the meshing process between the driven gear 10 and the driving gear 15, replacing the transmission function of the spiral drum 3 until the last stones or grass roots fall into the inner cavity of the discharge trough 8 at the end, which is used to store the separated impurities other than the fine soil;

[0030] Step five, a large amount of soil falling from the gap between the spiral drum 3 is relatively loose, and overflows from the spacing set between the rake hooks 4. The raised soil pile overflows from the gap between the rake hooks 4 or rolls to a relatively concave position, so that the loose soil at the position of the rake hooks 4 is flattened during movement and then flows out, and the loose soil is spilled in a relatively flat state, and the tiller cavity 1 drives with the wheels 20 to leave the area that has been initially flattened after plowing.
