小型玉米脫粒機入料和脫粒裝置的設(shè)計
摘要 為了減少農(nóng)民在脫去玉米粒的時候時的勞動強度、提高其農(nóng)業(yè)生產(chǎn)效率,所以設(shè)計玉米脫粒機。該機主要有入料口、柵格式凹板和釘齒脫粒滾筒及傳動部件等組成。以電動機為動力源,動力由電動機輸出軸輸出,再通過傳動帶傳遞到釘齒脫粒滾筒上,釘齒脫粒滾筒配合柵格式凹板將玉米脫粒,玉米粒從柵格式凹板分離并排出機體外,而玉米芯從入料的另一端排出機體之外。其工藝流程:玉米穗通過入料斗進料口進入釘齒滾筒,在高速回轉(zhuǎn)釘齒滾筒的沖擊和玉米穗、釘齒滾筒,柵格式凹版的相互作用下被脫粒。脫下的籽粒通過柵格式凹版由出粒板滑出機體,而玉米芯則隨著螺旋排列的釘齒由出芯口排出機體。為了保證有玉米穗順利的喂入而不堵塞滾筒,進料口下底板應該有一定的斜度,玉米芯排出口應與籽粒排出口保持一定的距離,以免玉米芯與籽粒相混雜。玉米脫粒機的生產(chǎn)效率決定于配套動力的大小。其功率消耗可按1kw.h的功可脫600~1000kg已撥皮的玉米穗計算。未剝皮的玉米穗直接進行脫粒時,其生產(chǎn)率約為30%~50%。

外文摘要
Enters and threshers devices design of small scale corn threshing machine
Abstract
In oder to reducing a peasant during the period of the maize threshes, the intensity of labour, raises working efficiency , designs Corn threshing machine. Be machine's turn to have mainly enter expect that the mouth , bars form notch board and nail tooth the cylinder threshing and drive component etc. are composed of. Take electric motor as driving force source, driving force exports axis output from the electric motor , the nail tooth seed-husking cylinder threshes on the cylinder threshing again by the fact that belt delivery arrives at the nail tooth, coordinating bars form notch board with the corns, besides seeds complies with bars form notch board separation and the outside discharging airframe, but the maize core discharges airframe from another one end entering material.Its process flow :The corn ears though hopper entering the threshing device, under the high speed rolling cylinder which installed the nails crash and the corn ears squeeze with the notch board, the seed will be drained. Than drained seeds will through the board slipped outside. Cob drained outside under the spiral nails help.In oder to make corn ears fluently entering the body ,and can not clog th the body ,the steel board of the bottom of hopper, should be designed set a angle .The corncob escapement should maintain certain distance with the grain escapement, in order to avoid the corncob and the grain are mixed.Corn threshing's production efficiency decides in the necessary power size. Its power dissipation may be possible to escape 600~1000kg according to the 1kw.h merit to dial the corn skin computation. That has not skinned when directly the corn carries on the seed extraction, its productivity approximately is 30%~50%.
