畢業(yè)設(shè)計(jì)說明書（論文）中文摘要

多功能播種機(jī)是基于2BJXSZPY-2型節(jié)水穴灌施肥植保鋪膜填土壓膜播種機(jī)之上的農(nóng)用播種機(jī)器。
整機(jī)由拖拉機(jī)牽引，適用于各種土壤條件，可以播種棉花、花生、玉米、大豆、谷物等?？梢淮瓮瓿砷_溝、施肥、灑水、播種、覆土鎮(zhèn)壓、噴灑農(nóng)藥、覆膜及填土壓膜等多項(xiàng)作業(yè)。通過調(diào)整主軸高度調(diào)節(jié)器可以調(diào)節(jié)開溝深度，以實(shí)現(xiàn)不同的播種深度。調(diào)整主軸上地輪位置可以調(diào)整播種行距，其排種器與地輪相連，可以通過調(diào)整地輪行走盤直徑實(shí)現(xiàn)株距的調(diào)節(jié)，操作方便，播種精度高，且種子破碎率小。
本次設(shè)計(jì)重點(diǎn)設(shè)計(jì)播種機(jī)播種、覆膜系統(tǒng)。排種器由尼龍制成，質(zhì)量輕，減輕了整機(jī)的重量，且尼龍舀勺在舀種過程中不易傷種，降低了種子的破損率，提高的播種質(zhì)量。

Title   Multi-function sowing machine and seed 、cover the membrane designed                                
Abstract
Multi-function sowing machine who sow water-saving cave is it apply fertilizer plant protection spread membrane fill out whom soil pigeonhole membrane on the seeder agricultural to sow machine to irritate because of 2BJXSZPY-2 type. The complete machine is drawn by the tractor, is suitable for various kinds of soil conditions , can sow cotton , peanut , maize , soybean , grain ,etc. . But one is it ditch , apply fertilizer , sprinkle water , seed , cover soil not to suppress , spray insecticide , cover membrane and fill out soil pigeonhole such large items of homework as membrane ,etc. to finish. Can regulate the depth of ditching through adjusting the height adjuster of the main shaft , in order to realize different depth of sowing. It adjust main shaft Shangdi can adjust row spacing of sowing of the rounds of positions,last device of planting it and linked to wheel, can wheel walk records of diameter realize regulation of spacing in the rows , easy to operate through adjust, it is high to sow the precision, and the broken rate of seed is little. This design designs the seeder and seeds, covers the membrane system especially. Arranging the planting device and is made of nylon, quality is light, lighten the weight of the complete machine, and nylon ladle out spoon difficult wounded kind of ladling out a kind of course, reduce the damaged rate of the seed, quality of sowing improved.

Key words  Seeder  complete machine designed  seed  cover the membrane
