The invention discloses a peanut picking Jiqing selection device, which comprises a vibration rack installed on the screen frame in the screen frame in front of the crank, the swinging rod installed back with peanut plate from high to low with frame one before, in the plate surface is arranged on the front of a receiving area. The suction area is provided in the material receiving region behind, there is a cross flow fan is installed on the frame above the suction area, in the cross flow fan shell to suction from the screen surface 10 20 cm is equipped with a suction hood, in the screen of suction in a uniform mesh. The shape of the sieve is round, square or circular arc shaped at both ends. A length adjusting mechanism is arranged on the swinging connecting rod. The invention has the following advantages: 1, one-time cleaning separation, eliminating the two recycling devices, the cost is reduced; 2, peanut loss, improve the cleaning and separation effect; 3, with a cross flow fan instead of two centrifugal fan, reduce energy consumption, reduce air pollution.
【技术实现步骤摘要】
一种花生摘果机清选装置
本专利技术涉及农业机械,特别是一种安装在花生摘果机上实现一次性将花生果与茎秆、杂物进行清选分离的花生摘果机清选装置。
技术介绍
现有的花生摘果机清选装置,一种为离心风机配合具有一定倾斜度的输送带,以及二次回收装置和振动筛来实现清选,主要是根据花生果与茎秆、杂物的不同比重,通过前端的离心风机出风口正压气流将轻质杂物(包括轻质花生果)吹出机外,再通过后端离心风机将吹出机外的杂物吹上垛,花生果和少部分比重大的茎秆掉落到倾斜向下的输送带上,由于花生果和茎秆的物理特性不同,花生果沿着输送带滚落到振动筛上被送出机外装袋,少部分比重大的茎秆和少量没滚落下来的花生果沿着输送带送到二次回收装置进行重复清选分离;另一种为离心风机配合振动筛以及二次回收装置来实现清选,主要通过振动筛的往复运动,依靠离心风机出风口的气流,将不同比重的花生果与杂质清选分离。它们的共同缺点是:在清选分离过程中,少部分比重轻的花生果被风机吹出机外,造成损失,还有少部分花生果在输送带上没能及时滚落下料,和茎秆一起被送到二次回收装置上并被送到摘果滚筒内重复循环进行清选分离,导致花生果的清洁度 ...
