Description

Agricultural land leveling device

Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to an agricultural land leveling device.

Background Art

A grader is a tool that uses a scraper to level the ground in fields such as earthwork, agriculture, and municipal construction. It is usually set behind a large agricultural vehicle, driven by the agricultural vehicle and completes the work of leveling the soil during the movement.

As shown in FIG1 , an existing agricultural land leveling device is usually connected to a tractor or other agricultural machinery through a mounting frame and other structures when in use, and is driven by the tractor to move on the land surface. Since there is only a very small gap between it and the land surface, it can limit the excess soil residue and take away the excess soil to complete the soil leveling work. However, in actual operation, it is usually necessary to compact the leveled land to obtain a better leveling effect. However, the leveling work and the compaction work usually require two sets of agricultural machinery to be installed one after the other to work on the required land, which increases the construction cost and slows down the construction progress.

Utility Model Content

The purpose of the utility model is to solve the following problems existing in the prior art:

However, in actual operation, it is usually necessary to compact the leveled land to obtain a better leveling effect. However, the leveling work and the compaction work usually require two sets of agricultural machinery to be installed one after the other to work on the required land, which increases construction costs and slows down construction progress.

In order to solve the problems existing in the prior art, the utility model provides an agricultural land leveling device, including a scraper, an L-shaped bracket is installed on the surface of the scraper, a support rod is installed on the top of the L-shaped bracket, a connecting rod is pinned on the top of the support rod, a spring is installed at the bottom of one end of the connecting rod close to the scraper, a connecting shaft is installed at the bottom of the other end of the connecting rod through a support rod, and pressure rollers are installed at both ends of the connecting shaft.

The utility model provides an agricultural land leveling device.

Furthermore, the scraper is overall arc-shaped, and an L-shaped bracket is arranged on a convex side surface of the scraper.

Furthermore, the vertical portion of the L-shaped bracket is connected to the scraper, and the horizontal portion extends in a direction away from the scraper.

Furthermore, a through groove is provided at the top of the support rod, the connecting rod is located inside the through groove and the through groove is larger than the connecting rod.

Furthermore, mounting platforms are provided at both ends of the connecting rod, and rotating shafts are provided at the bottom of the two mounting platforms and are respectively connected to the spring and the connecting rotating shaft.

Furthermore, one end of the spring is connected to the bottom of the connecting rod and the other end is connected to the top of the vertical part of the L-shaped bracket, and the spring always remains in a relaxed state.

Furthermore, the connecting shaft is composed of a mounting column and shafts arranged at both ends of the mounting column, wherein a support rod at the bottom of the connecting rod is connected to the mounting column.

Compared with the prior art, the present invention has the following beneficial effects:

The utility model installs a scraper at the rear of the agricultural machinery, and the agricultural machinery drives the scraper to move when moving forward to complete the leveling work. The scraper drives the pressure roller to move through the L-shaped bracket during the movement. When the pressure roller moves, the connecting shaft is pushed by the spring at the other end of the connecting rod to generate downward pressure. The connecting shaft drives the pressure roller to always fit with the soil and press the soil downward, so that the leveled soil is pressed tightly. The operator only needs to perform the leveling work once to make the soil compact in a flat state, and there is no need to perform compaction work again, which saves construction costs and improves construction speed.
