【摘要】：根據(jù)《國家中長期科學(xué)和技術(shù)發(fā)展規(guī)劃綱要》總體部署要求------將我國農(nóng)業(yè)科技整體實力提升到世界前列與保障國家糧食安全倡導(dǎo)的節(jié)糧原則,針對當(dāng)前將“節(jié)糧、節(jié)能、智能化”作為國內(nèi)外散糧物流裝備的發(fā)展主題,結(jié)合國內(nèi)進出倉設(shè)備現(xiàn)已存在的技術(shù)基礎(chǔ),借鑒國內(nèi)外先進混凝土泵送系統(tǒng)的原理,并根據(jù)糧食物料特有的物理性能,特提出了一種新型散糧輸送設(shè)備——散糧輸送泵車。其工作原理為:泵送系統(tǒng)采用雙排糧食輸送缸交替工作。泵送機構(gòu)會在油缸的作用下,其中一個泵送活塞桿向前推送糧食,而另外一個活塞桿向后將糧食吸入糧食輸送缸中,為下一次向前輸送糧食做準(zhǔn)備。在活塞桿推送和吸入糧食,靠活塞桿的作用將糧食往前推進,實現(xiàn)糧食輸送�；剞D(zhuǎn)機構(gòu)主要通過小齒輪帶動大齒輪轉(zhuǎn)動,實現(xiàn)固定在回轉(zhuǎn)機構(gòu)上的臂架結(jié)構(gòu)輸糧管道一起隨大齒輪實現(xiàn)360°轉(zhuǎn)動。臂架在液壓推桿的作用下實現(xiàn)臂架伸縮自如,確保泵送系統(tǒng)在泵送高度和距離上的自由改變。本文針對散糧輸送泵車的工作原理,主要采用理論分析與數(shù)值計算相結(jié)合,對散糧輸送泵車的臂架結(jié)構(gòu)、回轉(zhuǎn)機構(gòu)、泵送系統(tǒng)等泵車關(guān)鍵部件的結(jié)構(gòu)進行了分析計算,提出了關(guān)鍵結(jié)構(gòu)的選型和結(jié)構(gòu)參數(shù)大小設(shè)計,并對整個散糧輸送泵車系統(tǒng)進行了三維建模和二維圖紙的生成。為后續(xù)散糧輸送泵車樣機試制、設(shè)備推廣提供了理論研究基礎(chǔ)。
[Abstract]:According to the requirements of the overall deployment of the National Medium- and Long-Term Science and Technology Development Program-- to promote the overall strength of China's agricultural science and technology to the forefront of the world and to safeguard the principle of grain saving advocated by the State food security, in view of the current "grain saving, energy saving" principle,Intelligent "as the development theme of bulk grain logistics equipment at home and abroad, combined with the existing technical basis of domestic equipment for entering and leaving warehouse, drawing lessons from the principle of advanced concrete pumping system at home and abroad, and according to the unique physical properties of grain materials,"A new type of bulk grain conveying equipment, bulk grain conveying pump, is put forward in this paper.Its working principle is: pump system adopts double row grain conveyer to work alternately.The pumping mechanism will push the grain forward with one pump piston rod under the action of the oil tank, while the other piston rod will breathe the grain back into the grain delivery tank in preparation for the next forward delivery of grain.When the piston rod pushes and inhale grain, the grain is pushed forward by the piston rod to realize grain transportation.The rotary mechanism mainly drives the big gear rotation through the pinion gear, realizes the grain transportation pipeline fixed on the rotary mechanism to realize 360 擄rotation together with the big gear.Under the action of hydraulic push rod, the boom can be telescoped freely to ensure the free change of pumping system in pumping height and distance.In view of the working principle of bulk grain conveying pump car, the paper mainly uses the combination of theoretical analysis and numerical calculation to analyze and calculate the structure of the key parts of the bulk grain conveying pump car, such as the arm structure, the rotary mechanism, the pumping system, and so on.The selection of key structures and the design of structural parameters are presented. The 3D modeling and two-dimensional drawing generation of the whole bulk grain conveying pump system are carried out.It provides a theoretical research basis for the subsequent trial production of bulk grain conveying pump vehicle and the popularization of equipment.
