Description

Rice seedling raising soil screening device Technical Field The utility model relates to a rice seedling raising soil screening device, and belongs to the technical field of agricultural machinery. Background The dry rice seedling raising technology is an agricultural technology for raising rice seedlings, and has the main advantages of short seedling age, strong seedlings, convenient management, and vital selection of seedling raising soil in the rice seedling raising process, and in order to improve the quality of the rice seedling raising soil, the rice seedling raising soil generally needs to be screened and filtered before being used, and hard soil blocks, broken stone blocks, rotten She Lanshe and other impurities in the seedling raising soil are removed through screening and filtering, so that the seedling raising effect is improved. In the prior art, the variety of the equipment for screening the seedling raising soil is more, for example, the authorized bulletin number is CN 221908189U, the patent name is China authorized utility model patent of the soil screening equipment for rice and wheat seedling raising, in the patent, the semi-mechanization of the seedling raising soil screening is realized by arranging the screening piece, the soil screening efficiency and the soil screening quality are improved, the screening piece is detachably arranged on the base through the mounting mechanism, and the mounting mechanism achieves the effect of convenient maintenance and replacement of the screening piece. The above patent, although realizing the screening of seedling raising soil, has the following problems in use: In the above-mentioned patent, the rice seedling raising soil that waits to screen need follow the side feeding of device, when in-service use, owing to be provided with a plurality of support columns in feed inlet and discharge gate department, lead to seedling raising soil hardly to follow the side feeding, simultaneously when the impurity that produces through the filtration can be blocked by the support column and can be detained in the screen cloth, often need dismantle the screen cloth when needs the clearance, lead to the efficiency of screening lower. In the above patent, the screen needs to be rolled into a cylindrical structure, which causes trouble in screen replacement and cannot be replaced quickly. 3.
