18、整車吸塵的效果。傳統(tǒng)吸嘴的結(jié)構(gòu)已越來(lái)越不適應(yīng)現(xiàn)在的道路條件，使用時(shí)間一長(zhǎng)，就暴露出許多缺陷。為提高掃路車清掃能力，改進(jìn)吸嘴結(jié)構(gòu)已迫在眉睫。</p><p>　　首先，分析一下掃路車吸嘴的結(jié)構(gòu)原理。它是由四面金屬板圍成，呈扁平狀，與地面圍成具有一定容積的腔體。頂部開(kāi)口通過(guò)橡膠吸管與箱體相通，同箱體形成一個(gè)密閉倉(cāng)體，前面為垃圾吸人口。整個(gè)吸嘴體由左右側(cè)及后部的橡膠滾輪支撐，調(diào)節(jié)滾輪機(jī)構(gòu)使吸嘴底邊離地面間隙約為5—10

19、mm。工作時(shí)，風(fēng)機(jī)不斷的抽吸，使密閉箱體處于真空狀態(tài)，這樣吸嘴的周邊就形成一定的負(fù)壓。前方由掃刷攏于車輛中部的垃圾受到真空吸力的吸引，沿著箱體通道而被收集在箱體內(nèi)。專用裝置停止工作時(shí)，吸嘴體通過(guò)提升機(jī)構(gòu)收到一定的高度，保證車輛運(yùn)輸行駛的安全性。因此針對(duì)吸嘴用途及使用環(huán)境，借鑒國(guó)內(nèi)外先進(jìn)掃路車吸嘴結(jié)構(gòu)，對(duì)傳統(tǒng)型吸嘴。</p><p>　　1地面不平坦時(shí)，保證吸嘴接地間除均勻傳統(tǒng)吸嘴的提升機(jī)構(gòu)采用平行四邊形機(jī)構(gòu)。該機(jī)

20、構(gòu)通過(guò)銷軸一端與吸嘴支耳相連，另一端與車架相連，通過(guò)鋼絲繩收放使吸嘴升降。吸嘴體通過(guò)銷軸可繞該機(jī)構(gòu)上下跳動(dòng)，前后左右方向無(wú)法擺動(dòng)。當(dāng)遇到地面高低不平時(shí)(如圖3)，由于吸嘴無(wú)法擺動(dòng)，隨著地面的升高，吸嘴體整體提升，而地勢(shì)低的一邊間隙就加大了，從而造成底部漏風(fēng)，吸力下降，地面無(wú)法清掃干凈。新型吸嘴就能克服這種道路條件帶來(lái)的問(wèn)題。吸嘴升降直接由油缸的伸縮來(lái)控制。油缸一端通過(guò)U形卸扣與吸嘴支耳相連，油缸為單作用缸，吸嘴放下時(shí)，活塞桿伸長(zhǎng)，腔內(nèi)無(wú)

21、壓力，吸嘴隨路面高低而升降，油缸也會(huì)跟隨伸縮，使吸嘴不受約束。前方導(dǎo)向桿通過(guò)鉸接機(jī)構(gòu)與吸嘴相連。鉸接機(jī)構(gòu)由鉸接座和銷軸I、銷軸H組成。鉸接座的兩個(gè)銷孔成十字交叉布置，銷軸I連接導(dǎo)向桿和鉸接座，銷軸n連接鉸座和吸嘴體。吸嘴體可繞銷軸I前后擺動(dòng)，繞銷軸n左右擺動(dòng)。當(dāng)路面高低不平時(shí)，吸嘴始終與地面保持平行，這樣離地間隙也均勻不變，風(fēng)機(jī)吸力也不受影響，同時(shí)降低對(duì)地面撞擊的噪音，提高吸嘴的耐用性。</p><p>　　2提

22、商對(duì)密度大、多而厘、有粘性的垃圾的吸力沙土型垃圾比較濕，壓實(shí)后對(duì)地面具有一定的附著力，傳統(tǒng)型吸嘴需靠提高風(fēng)機(jī)轉(zhuǎn)速才能吸干凈。新型吸嘴尾部加裝臥式掃刷(如圖Zb)就能提高清掃效率。臥式掃刷裝在吸嘴后部，由5把圓形掃刷固定在心軸上，液壓馬達(dá)帶動(dòng)心軸使掃刷高速旋轉(zhuǎn)。如果垃圾具有一定的粘性，真空吸力不足以克服垃圾對(duì)地面附著力，需通過(guò)掃刷的滾動(dòng)，使垃圾揚(yáng)起，真空吸力作用面積增大。根據(jù)壓強(qiáng)、壓力公式F-尸XS壓強(qiáng)不變，作用面積加大，壓力就變大，這樣

23、在相同的風(fēng)機(jī)轉(zhuǎn)速下，箱內(nèi)的氣體壓強(qiáng)一致，垃圾受到的真空吸力(即壓力)就大，就容易被抽吸進(jìn)垃圾箱體。此種機(jī)構(gòu)清掃潮濕地面上枯枝爛葉特別有效。根據(jù)試驗(yàn)結(jié)果，兩種吸嘴在相同路面作業(yè)時(shí)，新3提高滾輪的使用壽命，降低使用成本新型吸嘴尾部和車架之間裝有懸掛拉簧、調(diào)節(jié)筒和鏈條。安裝時(shí)，先調(diào)節(jié)好鏈條長(zhǎng)度，保持拉直狀態(tài)，使前后滾輪著地。調(diào)節(jié)筒由兩端左右旋螺桿和中部套筒組成，旋轉(zhuǎn)套筒使拉伸彈簧拉長(zhǎng)，直到彈簧拉力接近而略小于吸嘴的重力。吸掃式路面清掃車具有路

24、面清掃范圍寬、連續(xù)工作里程長(zhǎng)、清掃保潔效率高、適應(yīng)性好等特點(diǎn)。由于其吸掃裝置對(duì)微細(xì)垃圾及塵埃具有良好的吸拾、除塵和輸</p><p>　　大型吸掃式清掃車采用定型汽車底盤和雙發(fā)動(dòng)機(jī)驅(qū)動(dòng)形式,其行走系統(tǒng)具有汽車行駛的獨(dú)立性和工作可靠性,同時(shí)副發(fā)動(dòng)機(jī)又可滿足吸掃系統(tǒng)對(duì)動(dòng)力的要求。掌握清掃車的關(guān)鍵應(yīng)用技術(shù),正確使用,合理維護(hù),對(duì)保持清掃機(jī)械正常運(yùn)轉(zhuǎn)、提高出勤率和延長(zhǎng)機(jī)械使用壽命有著十分重要的作用。</p>

25、<p>　　合理選用吸掃裝置的結(jié)構(gòu)形式國(guó)產(chǎn)吸掃式清掃車的吸掃裝置有4種布置形式:中置四掃盤后置吸嘴式、中置四掃盤加后置臥刷吸嘴式、前置二掃盤加中置二掃盤吸嘴式和中置二掃盤加中置臥刷雙吸嘴式。中置四掃盤后置吸嘴式清掃車是在吸收國(guó)外先進(jìn)技術(shù)的基礎(chǔ)上,結(jié)合國(guó)內(nèi)實(shí)際情況開(kāi)發(fā)出的新一代路面清掃車,具有清掃視線好、易操作、清掃效果好等特點(diǎn),其清掃寬度可達(dá)3.5 m,清掃速度可高達(dá)30 km/h,垃圾吸入粒度大(最大可達(dá)125 mm),掃

26、凈度可高達(dá)97.2%,且對(duì)周圍環(huán)境污染小,最適合清掃剛性水泥或其它硬性路面。采用前置式掃盤的清掃車具有清掃直觀等優(yōu)點(diǎn),適合清掃城市道路和高等級(jí)瀝青路面,但在路面灰塵較多、壓塵不夠理想的情況下不宜使用,以免由于揚(yáng)塵影響駕駛員視線。由于揚(yáng)塵的影響,此種前置式掃盤清掃車的清掃速度受到一定限制,通常應(yīng)控制在3~20 km/h。</p><p>　　采用中置二掃盤加中置臥刷滾掃裝置的清掃車,由于掃盤間距偏窄(清掃寬度約為2

27、.2m)清掃能力相對(duì)較低。通常其吸入粒度較小,二次污染較大,故清掃速度不宜過(guò)高,只適宜清掃城市</p><p>　　道路或灰塵較少的瀝青路面兩側(cè)。根據(jù)高等級(jí)公路路面性質(zhì)、路面狀況、地理環(huán)境和氣候等因素,合理選用清掃車吸掃裝置的結(jié)構(gòu)及布置形式,是提高路面清掃效率的首要問(wèn)題。最佳作業(yè)速度的選擇與控制如何選擇和控制清掃車主車的行駛速度和驅(qū)動(dòng)清掃工作裝置的轉(zhuǎn)速,對(duì)清掃使用效能有著直接的影響。實(shí)踐證明,灰塵覆蓋量和塵埃粒度
