The invention belongs to the field of agricultural equipment, and specifically relates to a screening machine, which comprises a support and a screen barrel rotated in a hollow position on the support. A screen mesh is arranged on the circumference of the screen barrel, and a drive shaft I through the screen barrel is arranged in the screen barrel. One end of the drive shaft I is rotated and connected with the support through a left bearing and a left bearing seat, and the other end of the drive shaft I is rotated and connected with the support through a right bearing and a right bearing seat. The invention is connected with the rotation of the bracket; the structure of the device is simple, the use is safe, convenient and the scope of application is wide. The bed soil enters the sieve barrel through the inlet and outlet of the sieve barrel. At the same time, it is crushed by the crushing blade and then rotated by the sieve screen to mix and screen. Because the sieve barrel is inclined, large stones and debris are pushed to the outlet of the sieve barrel to discharge, and the soil particles reaching the standard are The soil particles can meet the requirement of bed soil for mechanical seedling cultivation, which can protect the seedling needle of transplanter very well, and will not leak and stick seedlings.
【技术实现步骤摘要】
一种筛选机
本专利技术涉及农业设施领域,具体地涉及一种筛选机。
技术介绍
水稻播种插秧育苗的床土及蔬菜花卉秧盘育苗床土需要粉碎、搅拌和筛选,将大块的石子和杂物被推到废料口排出,达标的土粒从筛网下出料口排出,保证筛选过的土粒达到机械育苗的床土要求,这为后续机插时能很好的保护插秧机的秧针,且不会漏秧卡秧,因此,很有必要专利技术一种简单易携带的床土粉碎、搅拌和筛选功能为一体的多功能设备。
