Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a device for rapid ground leveling before sowing. Background Technology

[0002] Leveling the ground before sowing is a crucial basic step in agricultural cultivation, which has a profound impact on the entire process of crop growth. A level ground makes the soil fine and uniform, allowing seeds to make close contact with the soil, which is conducive to the absorption of water and nutrients and successful germination. In addition, a level ground can ensure that irrigation water or rainwater penetrates evenly, avoiding water accumulation in low-lying areas (causing seed rot, root rot, and lack of oxygen) and water shortage in high-lying areas (leading to drought and seedling loss).

[0003] Current leveling devices use leveling shovels with a fixed width, which cannot be flexibly widened to accommodate different ground conditions, thus affecting the leveling speed. Therefore, we propose a rapid ground leveling device before sowing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid ground leveling device before sowing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid ground leveling device before sowing includes a support plate welded to a leveling trolley, a mounting frame welded to the side wall of the support plate, and a widening leveling mechanism connected to the mounting frame via a height adjustment mechanism.

[0007] The widening leveling mechanism includes a main leveling shovel, a protective cover fixedly connected to the top outer wall of the main leveling shovel, two widening auxiliary shovels slidably connected to the main leveling shovel, a first servo motor fixedly installed on the middle outer wall of one side of the protective cover, a gear fixedly mounted on the output shaft of the first servo motor, and two racks meshing with the gear.

[0008] The height adjustment mechanism includes a vertical lead screw rotatably mounted in the mounting frame, a lifting seat, a lead screw nut fixedly embedded in the lifting seat and threadedly connected to the vertical lead screw, and a second servo motor fixedly mounted on the top outer wall of the mounting frame.

[0009] Preferably, the two racks are arranged symmetrically and staggered, and the gear and the two racks are all located inside the protective cover.

[0010] Preferably, two symmetrical sliding tracks are provided on one side of the main leveling shovel, and two sliders are welded to the widened side wall of the secondary shovel, with the outer walls of the two sliders slidably connected to the inner walls of the two sliding tracks respectively.

[0011] Preferably, both racks are fixedly connected to two widened auxiliary shovels respectively via connectors, and two sliding openings are provided on one side of the protective cover, and the outer walls of the two connectors are slidably connected to the inner walls of the two sliding openings respectively.

[0012] Preferably, the output shaft of the second servo motor passes through the top of the mounting bracket and is coaxially and fixedly connected to the top of the vertical lead screw via a coupling. The lifting seat is fixedly connected to the protective cover via a connecting plate, and a storage battery is fixedly installed on the upper part of the support plate.

[0013] Preferably, two columns are symmetrically welded inside the mounting frame, and two linear bearings are fixedly embedded inside the lifting seat, with the two linear bearings being movably connected to the two columns respectively.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. It is equipped with a widening leveling mechanism. The gear is controlled to rotate forward by the first servo motor. Then, under the connection effect of the two connecting parts, the two racks meshing with the gear will drive the two widening auxiliary shovels to move away from each other. This allows the usable width of the leveling shovel to be flexibly widened according to the leveling width of different ground surfaces, which is conducive to improving the leveling speed.

[0016] 2. It is equipped with a height adjustment mechanism. The vertical screw is rotated forward and backward by the second servo motor. Then, the screw nut connected to the vertical screw will drive the lifting seat to move up and down. This allows for flexible adjustment of the leveling height of the entire widening leveling mechanism to meet the leveling needs of different ground surfaces. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1-4 A rapid ground leveling device before sowing includes a support plate 2 welded to a leveling trolley 1. A storage battery 18 is fixedly installed on the upper part of the support plate 2, which can power the electrical components of the entire device. A mounting frame 3 is welded to the side wall of the support plate 2, and a widening leveling mechanism is connected to the mounting frame 3 through a height adjustment mechanism.

[0025] Specifically, the widening leveling mechanism includes a leveling main shovel 5, a protective cover 4 fixedly connected to the top outer wall of the leveling main shovel 5, two widening auxiliary shovels 6 slidably connected to the leveling main shovel 5, a first servo motor 7 fixedly installed on the middle outer wall of one side of the protective cover 4, a gear 8 fixedly mounted on the output shaft of the first servo motor 7, and two racks 9 meshing with the gear 8.

[0026] Furthermore, the two racks 9 are arranged symmetrically and staggered. The gear 8 and the two racks 9 are all located inside the protective cover 4. Two slides 11 are symmetrically opened on one side of the leveling main shovel 5. Two sliders are welded to the side wall of the widened secondary shovel 6. The outer walls of the two sliders are slidably connected to the inner walls of the two slides 11 respectively. The two racks 9 are fixedly connected to the two widened secondary shovels 6 respectively through connectors 10. Two sliding openings are opened on one side of the protective cover 4. The outer walls of the two connectors 10 are slidably connected to the inner walls of the two sliding openings respectively.

[0027] The working principle of this embodiment is as follows: First, when widening is required, the first servo motor 7 controls the gear 8 to rotate forward. Then, under the connection effect of the two connecting parts 10, the two racks 9 meshing with the gear 8 will drive the two widening auxiliary shovels 6 to move away from each other, thereby flexibly widening the usable width of the leveling shovel according to the leveling width of different ground surfaces, which is beneficial to improving the leveling speed. Second, when not in use, the first servo motor 7 simply controls the gear 8 to rotate in the reverse direction. Then, under the connection effect of the two connecting parts 10, the two racks 9 meshing with the gear 8 will drive the two widening auxiliary shovels 6 to move closer together to achieve the storage effect.

[0028] Example 2, refer to Figure 1-2 and Figure 5 This embodiment is an optimization based on embodiment 1. Specifically, the height adjustment mechanism includes a vertical lead screw 12 rotatably installed in the mounting frame 3, a lifting seat 13, a lead screw nut 14 fixedly embedded in the lifting seat 13 and threadedly connected to the vertical lead screw 12, and a second servo motor 15 fixedly installed on the top of the mounting frame 3.

[0029] Furthermore, two columns 16 are symmetrically welded inside the mounting frame 3, and two linear bearings 17 are fixedly embedded inside the lifting seat 13. The two linear bearings 17 are movably connected to the two columns 16 respectively. Through the cooperation between the two columns 16 and the two linear bearings 17, the stability of the linear movement of the lifting seat 13 can be guaranteed.

[0030] Furthermore, the output shaft of the second servo motor 15 passes through the top of the mounting bracket 3 and is coaxially and fixedly connected to the top of the vertical lead screw 12 via a coupling; the lifting seat 13 is fixedly connected to the protective cover 4 via the connecting plate 19.

[0031] The working principle of this embodiment is as follows: the vertical lead screw 12 is rotated forward and backward by the second servo motor 15, and then the lead screw nut 14, which is threadedly connected to the vertical lead screw 12, drives the lifting seat 13 to move up and down, so that the leveling height of the entire widening leveling mechanism can be flexibly adjusted to meet the leveling requirements of different ground surfaces.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
