摘 要
本文介紹了一種大棚蔬菜種植耕整地機(jī)械—小型溫室松土機(jī)的設(shè)計(jì)方案。對(duì)松土機(jī)的國(guó)內(nèi)外情況進(jìn)行了分析和對(duì)比，重點(diǎn)進(jìn)行了發(fā)動(dòng)機(jī)的選擇，變速器的設(shè)計(jì)，部分零件的設(shè)計(jì)，傳動(dòng)路線的設(shè)計(jì)以及對(duì)滾齒軸的設(shè)計(jì)等。
該機(jī)動(dòng)力由發(fā)動(dòng)機(jī)輸出經(jīng)皮帶傳動(dòng)，傳給變速箱進(jìn)行減速，二級(jí)傳動(dòng)采用鏈傳動(dòng)。滾齒刀軸的設(shè)計(jì)采用三段式，中間為空心的圓管鋼，兩邊采用實(shí)心軸，可制出軸肩來(lái)安裝軸承和端蓋。裝有行走機(jī)構(gòu)和限深鏟，耕后地表平整，能夠解決以往小型旋耕機(jī)功率小、結(jié)構(gòu)復(fù)雜、操作麻煩、耕深淺等問(wèn)題，適合大棚耕整地工藝的要求。

Abstract
In this paper, the cultivator,，one of the important small agricultural machines, is designed based on comparing and researching the developing situation of cultivator at home and abroad. The design includes the choice of motor, the choice of transmission, the design of some parts and the design of the cultivator knife-axis etc.
The plowing outgoing power is from engineering to the gearbox using belts，after that be transferred to the arbor of rotate knife. Between gearbox and the arbor of rotate knife adopt chains to transmit; The design of arbor of rotate knife adopt three parts, the middle part is hollow rolled steel ，two side parts is solid rolled steel, may process Shoulder-axis to lay on roller bearing and Cover. The surface is neat after till, the cultivator designed in the paper can overcome the problems of small-power , complex structure, trouble operation, low plowing depth etc. It can meet the request of greenhouse.
