Technical Field
[0001] The utility model relates to the field of impurity removal devices, in particular to a portable saline-alkali rice impurity removal device. Background Art
[0002] Traditional large-scale weed removal devices are usually used in specific places such as grain stations, and are not easy to move to different places for use. The portable saline-alkali rice weed removal device is different from the traditional large-scale weed removal device. It is smaller in size and easier to load and move. It is a modern agricultural machinery equipment that integrates multiple functions such as screening and winnowing. It is made of high-quality steel plates, rust-proofed, and has a sturdy and durable structure. It also has good mobility and is easy to transfer between different work sites.
[0003] The existing portable saline-alkali rice impurity removal device comprises a main frame and an impurity removal component, wherein the impurity removal component comprises a screening box, and the operation steps are as follows: firstly, unscreened saline-alkali rice is placed in the screening box, and impurities of different sizes and rice grains are separated by vibration, and finally, the dust and soil particles with the smallest volume fall to the bottom of the screening box. Due to their small volume and light weight, it is difficult to completely shake them off only by the vibration of the screening box during screening. Therefore, after long-term use of the saline-alkali rice impurity removal device, a lot of dust and soil particles will accumulate at the bottom of the screening box. In addition, due to the small space at the bottom of the screening box, it is not easy to clean.
