Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a land leveling and smoothing device for land preparation operations. Background Technology

[0002] With the continuous improvement of productivity and the rapid development of the rural economy, more and more agricultural machinery has been promoted and applied. The emergence of agricultural tillage machines, threshers, harvesters, etc., has greatly liberated rural labor and improved agricultural production efficiency. Tillage refers to a series of soil cultivation measures carried out before crop sowing or transplanting. Tillage operations include leveling the land and loosening the soil, but the existing tillage machinery has a relatively complex structure.

[0003] Chinese patent CN217742162U discloses a land leveling device that uses leveling components and rolling rollers to level and compact the soil in the repair area. Compared with traditional structures, this device uses a leveling scraper that moves with the vehicle to level the soil in the repair area, while the output end of the hydraulic cylinder applies downward pressure to the frame plate, so that the rolling rollers compact the soil while rolling with the vehicle, thereby improving the flatness and compactness of the repair area.

[0004] However, the following defects and shortcomings exist in the application process: the flat scraper is a single vertical plate structure with a curved lower end. Therefore, it can flatten the protrusions on the ground surface during the forward movement. However, this will also cause it to be subjected to the reaction force generated by the soil during the forward movement, which can easily cause it to deform over time. The angle and pressure cannot be adjusted as needed. Therefore, we propose a new type of ground leveling device to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a simple, economical and practical land leveling device that allows for adjustment of the angle and pressure of the trowel as needed for land leveling operations.

[0006] This utility model discloses a floor leveling device, which is mounted on a frame and includes a trowel. Supports are connected to both sides of the trowel. One end of each support is hinged to the trowel and connected to an adjustment device I. The other end of each support is connected to an adjustment device II. The adjustment device I includes a support plate, an adjustment screw I, a pressure spring I, and an adjustment nut I. The pressure spring I is sleeved on the adjustment screw I. The lower end of the adjustment screw I is hinged to the trowel, and the upper end of the adjustment screw I passes through the support plate and is threadedly connected to the adjustment nut I.

[0007] The structure of the adjustment device II includes a bracket connecting plate, an adjusting screw II, a pressure spring II, and an adjusting nut II. The pressure spring II is sleeved on the adjusting screw II. The lower end of the adjusting screw II is hinged to the bracket connecting plate, and the upper end of the adjusting screw II passes through the end of the bracket and is threadedly connected to the adjusting nut II. The upward extension of the bracket connecting plate is hinged to the bracket.

[0008] Preferably, the squeegee is an arc-shaped plate with a higher front and lower back, and is bent.

[0009] Preferably, the support plate has a through hole, one end of which is fixedly connected to the bracket, and the other end is sleeved with the adjusting screw I through the through hole.

[0010] Working principle of this utility model:

[0011] This utility model relates to a land leveling and sizing device applied to agricultural machinery, capable of completing land leveling operations. It includes a sizing plate, with two sets of supports connected to both sides of the sizing plate. One end of each set of supports is hinged to the sizing plate and connected to an adjustment device I; the other end of each set of supports is connected to an adjustment device II. Adjustment device I allows for adjustment of the height and pressure of the sizing plate, while adjustment device II allows for adjustment of the angle and pressure of the sizing plate. During land leveling operations, adjustment device I applies pressure to the supports and the sizing plate, while adjustment device II applies pressure to the sizing plate while simultaneously adjusting its angle. Suitable for land leveling operations in various soil conditions, the device allows for adjustment of the sizing plate's angle and pressure according to different soil conditions, and its structure is simple and practical.

[0012] Compared with the prior art, the advantages of this utility model are: it is suitable for land preparation operations, can be adjusted at any time according to different land conditions, and the angle and pressure of the trowel can be adjusted as needed, making it more adaptable, simple in structure, and economical and practical.
