The utility model relates to a self-propelled peanut combine harvester, relating to peanut harvesting machinery. The utility model comprises a walking vehicle, a power device, a fruit collecting box, a twisting dragon, a fulcrum frame, a main transmission shaft, and a peanut harvesting device. Peanut harvesting device comprises a machine frame, coulter, harvest, soil shaking lifter rod, a depth limiting wheel, clamping device and the threshing conveyor chain, vibration sieve. The utility model is characterized in that a fruit removing device is arranged at the front of the eight inlet of a chain conveying chain at the front end of the conveying chain, and the peanut seedling is fed by the feeding inlet of the eight shape, and the fruit seedling is clamped and conveyed, and the fruit is started to be taken off even as the fruit enters the fruit removing device. The invention has the beneficial effects that the peanut combine harvester omits the existing distance harvesting and gripping and shaking conveying section of the harvesting captain. After the clamping is carried out, the fruit removing device and the vibrating sieve are simultaneously carried out to screen the soil and the net fruit. The utility model does not have the problems of long distance clamping and conveying, and simultaneously shaking soil and causing more falling fruits, thereby thoroughly overcoming the defects of the existing harvester. The vibrating screen is provided with a grid bar air leakage vibrating screen formed by welding steel rollers, and the side view is sawtooth shaped, and the sieve soil effect is better. The invention has the advantages of high harvesting efficiency, little fruit loss and good effect.
【技术实现步骤摘要】
自走式花生联合收获机
:本专利技术涉及农业机械,主要涉及花生收获机械,特别涉及自走式花生联合收获机。
技术介绍
:目前国内自走式花生联合收获机,不管是轮式还是履带式联合收获机,一般由犁刀、链夹持输送、抖土器、脱果器、振动筛等部分构成,有的公司厂家已构成规模生产,生产销售形势曾一度很是红火,但好景不长,不到二年时间,很快陷入萧条,很快失去了市场,失去了用户,且到了无人问津的地步。经调查,群众的反应是,机器好看不好用,看着挺好的联合收获机,就是光掉花生,好不容易种出来的花生收获时又大量掉到地里,要再从土里复收回来就很困难。遗憾的是,到目前这些厂家还至今未找到掉果多的原因、也未找到解决的办法。
技术实现思路
:本专利技术的目的是分析找出现有联合收获机掉果多的原因,提供一种全新的自走式花生联合收获机,以克服现有联合收获机掉果多的严重缺陷。少掉果、颗粒归仓,增加农民收益,必将受到农民欢迎。本专利技术的内容是:一种自走式花生联合收获机,包括行走车1、驾驶室2、装于行走车底盘上的动力装置3、集果箱4、提升绞龙5、支点架6、主传动轴16、花生收获装置7。所述花生收获装置包括收获机架71、犁刀72、抖土器73、扶禾杆74、限深轮75、夹持输送链8、脱果器9和震动筛10。特征在于,紧接夹持输送链前端“八”字形喂入口其后之下方设置脱果器9,经“八”字形喂入口20喂入的花生被夹持输送随即便进入脱果器被开始脱果,脱果器下方设有震动筛10。本专利技术所产生的有益效果:现有花生联合收获机掉果多的根本原因是,花生被夹持输送的路径较长、夹持过程进行抖土、其后才进入脱果机构,在较长距离的夹持输送 ...
