摘要：礦山生產(chǎn)的全過程離不開礦山運輸和提升工作。因此，運輸和提升工作的好壞直接關系到礦山生產(chǎn)能否正常高效進行。如果說運輸線路是礦山生產(chǎn)的動脈，那提升設備則是其咽喉，可見其重要性和必要性。肥料對于農(nóng)作物的作用非常重要，隨著耕地面積的不斷減少，糧食的產(chǎn)量顯得尤其重要。因此，肥料的生產(chǎn)非常重要。
BB肥料（Blending bulk fertilizer）根據(jù)作物需肥規(guī)律和土壤供肥特性進行配制，含氮、磷、鉀三種元素，也可根據(jù)作物需要添加中、微量元素。 肥料具有如下優(yōu)點，一是養(yǎng)分配比靈活科學合理，可以根據(jù)不同作物進行調(diào)配；二是價格便宜，同等養(yǎng)分的BB肥料比進口復合肥料便宜；三是配送方便。
提升機為通過改變勢能進行運輸?shù)臋C械設備。提升機是一種被普遍采用的垂直輸送設備，廣泛地應用于建材、電力、冶金、機械、化工、輕工、有色金屬、糧食等各工業(yè)部門。可以滿足用戶對提升機的不同性能要求。
本課題是為了制造BB肥生產(chǎn)提升設備。 主要由提升斗、提升系統(tǒng)、機架等組成。工作原理：將大顆粒尿素、鉀肥、磷肥、填充料等按配方要求比例計算后，分別投入斗式提升機料斗，料斗經(jīng)由鋼絲繩牽引沿著軌道上升，提升到一定高度碰到行程開關，斗門打開，肥料卸下，料斗空載回起點。

Abstract: The role of fertilizer for the crops is very important, as the shrinking arable land, grain production is especially important. Therefore, fertilizer production is very important.
fertilizer (Blending bulk fertilizer) under the laws of crop fertilizer and soil characteristics for the preparation of fertilizer, nitrogen, phosphorus and potassium are three elements can be added according to crop needs, the trace elements. BB fertilizer has the following advantages, first, nutrients and flexible scientific and rational allocation according to different crops; second is cheap, the same nutrients fertilizer compound fertilizer cheaper than imports; third, to facilitate distribution.
Hoist by changing the potential energy for the transport of machinery and equipment. Hoist is a widely used vertical transportation equipment, widely used in building materials, electric power, metallurgy, machinery, chemicals, light industry, metals, food and other industries. Meet the different users on elevator performance requirements.
The issue is to create BB Fertilizer Production Hoisting Equipment. Mainly by enhancing the Big Dipper, hoisting system, a framework. Works: The large granular urea, potash, phosphate, fillers and other requirements according to the ratio calculation formulas were put bucket elevator hopper, the hopper through the wire rope traction along the track up to a certain height to enhance hit limit switch, open The door , fertilizer unloading, hopper back to the starting point empty.
