Description

Technical Field

[0001] The utility model relates to the technical field of corn planting, in particular to a rotary tillage device for corn planting. Background Art

[0002] Corn is a common coarse grain. Eating it in moderation usually provides nutrition and energy, promotes defecation and other benefits. During the corn planting process, the soil needs to be loosened to facilitate corn planting. Therefore, in order to improve the efficiency of corn planting, rotary tillage is used to treat the soil. The rotary tiller has the functions of breaking the plow bottom layer, restoring the soil plow layer structure, improving the soil's water retention capacity, eliminating some weeds, reducing pests and diseases, leveling the surface and improving the standards of agricultural mechanization operations.

[0003] When using rotary tillage equipment to till the soil, a robotic arm is usually required to control the height of the rotary tillage device to control the rotary tillage device to adjust the soil tillage depth. However, the robotic arm moves on the land, causing the robotic arm to vibrate as the drive device moves, which will cause the depth of the rotary tillage device to change. After the rotary tillage depth changes, the rotary tillage depth will be different, and the rotary tillage depth will be too deep, which will affect the subsequent corn planting efficiency. So far, we have proposed a rotary tillage device for corn planting. Utility Model Content

[0004] In response to the shortcomings of existing rotary tillage equipment for corn planting, the utility model provides a rotary tillage equipment for corn planting, which has a roller that moves on the ground, and the height of the roller is adjusted with the rotation of the inclined rod. In this way, when the roller rolls on the ground, the rotary tillage depth of the rotating wheel is ensured to be fixed, and the rotary tillage depth can be adjusted conveniently, thereby solving the problems raised in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a rotary tillage device for corn planting, comprising a mounting frame, a mounting sleeve installed inside the lower end of the mounting frame through a bearing, a pulley 2 fixedly connected to the outside of the mounting sleeve and located on the inner side of the mounting frame, a rotating column movably sleeved inside the mounting sleeve, a rotating wheel disc movably sleeved outside the rotating column, a sealing sleeve fixedly connected to the side of the mounting frame, an inclined rod movably sleeved inside the sealing sleeve, and a roller installed at the lower part of the inclined rod.

[0006] Preferably, the external thread of the mounting sleeve is sleeved with a first nut, and the bearing is clamped between the second pulley and the first nut.

[0007] Preferably, a first fastening bolt is installed inside the mounting sleeve, and the first fastening bolt is threadedly installed inside the rotating column.

[0008] Preferably, the middle part of the rotating column is movably sleeved with a limit sleeve and spring steel, wherein a group of limit sleeves are installed on each side of the spring steel, the two ends of the rotating column are diamond-shaped, the rotating wheel is sleeved on the outside of the diamond column, and the external thread of the rotating column is in turn sleeved with a second nut, and the second nut is arranged on the side of the rotating wheel.

[0009] Preferably, a mounting seat is installed inside the rotating wheel through a second fastening bolt, and a rotary tillage blade is fixedly connected to the outside of the mounting seat.

[0010] Preferably, a circular chute is provided inside the inclined rod, and the screw is arranged inside the circular chute. At the same time, the outside of one side of the inclined rod is fixedly connected with a screw, and a nut is installed on the outside of the screw.

[0011] Preferably, a pulley 1 is installed on the inner side of the roller, a belt is sleeved on the outer side of the pulley 1, and the belt is sleeved on the outer sides of the pulley and the pulley 2.

[0012] Compared with the existing rotary tillage equipment for corn planting, the utility model has the following beneficial effects:

[0013] 1. The rotary tillage equipment for corn planting is arranged on the inner side of the rotating disc through a limit sleeve and spring steel. When the second nut is rotated at the same time, the second nut pushes the rotating disc to move inward, that is, the position of the rotating disc outside the rotating column can be adjusted. At the same time, when the rotating disc rotates, the rotating disc can drive the rotary tillage blades to rotary till the soil, thereby improving the convenience of adjusting the rotary tillage position.

[0014] 2. The rotary tillage equipment for corn planting controls the depth and inclination of the roller on the inner side of the mounting frame by rotating the inclined rod. By adjusting the height difference between the roller and the rotary tillage blade, the rotary tillage blade can control the soil tillage depth when the roller rolls on the ground. At the same time, when the roller rotates, the roller drives the belt to rotate synchronously, and the belt can drive the second pulley to rotate synchronously, that is, when the roller rolls on the ground, it can automatically drive the rotary tillage blade to provide power.
