Description

Technical Field

[0001] This utility model relates to a rice seedling soil screening device, belonging to the field of agricultural machinery technology. Background Technology

[0002] Dry rice seedling raising technology is an agricultural technique for raising rice seedlings. Its main advantages are short seedling age, strong seedlings, and convenient management. The selection of seedling soil is crucial in the rice seedling raising process. In order to improve the quality of rice seedling soil, it is generally necessary to screen and filter it before use. Through screening and filtering, impurities such as hard soil clods, gravel, rotten leaves and other impurities in the seedling soil are removed to improve the seedling raising effect.

[0003] There are many types of equipment used for screening seedling soil in the existing technology. For example, there is a Chinese authorized utility model patent with authorization announcement number CN 221908189U and patent name: a soil screening device for rice and wheat seedling raising. In the above patent, the setting of screening components realizes the semi-mechanization of seedling soil screening, which improves the efficiency and quality of soil screening. The screening components can be detachably installed on the base through the installation mechanism, which achieves the effect of convenient maintenance and replacement of the screening components.

[0004] Although the above-mentioned patent has achieved the screening of seedling soil, there are some problems in its use:

[0005] In the aforementioned patent, the rice seedling soil to be screened needs to be fed from the side of the device. In actual use, because there are multiple support columns at the inlet and outlet, it is difficult for the seedling soil to be fed from the side. At the same time, when impurities are generated after filtration, they will be blocked by the support columns and remain in the screen. When cleaning is required, the screen often needs to be removed, resulting in low screening efficiency.

[0006] In the aforementioned patent, the screen needs to be rolled into a cylindrical structure, which makes screen replacement more troublesome and not quick.

[0007] 3. In the existing technology, after the screening device screens the seedling soil, the screened seedling soil is generally collected by a receiving box. The existing receiving box usually needs to be placed at the bottom of the device. During the above placement process, the size of the receiving box must match the screening device, otherwise it is not easy to place it at the bottom of the screening device. At the same time, during the placement process, the operator may touch the screening device, which may cause injury to the operator. Summary of the Invention
