中文摘要:针对现有花生摘果装置普遍存在的摘果损伤率高且易缠绕、堵塞和排秧困难等问题,以及满足我国两段式花生收获的捡拾联合收获机摘果装置研究需要,在研究两段式花生收获方式下花生植株性状与特点基础上,设计了一种螺杆弯齿式轴流全喂入花生摘果装置,摘果作业时,花生植株受螺杆、弯齿和凹板筛共同作用使花生荚果从花生茎秆上脱离,因螺杆有螺旋角、弯齿有倾角,花生植株沿摘果滚筒圆周运动的同时,受轴向分力作用排出机外,在保证高摘净率和低损伤率的同时避免植株在滚筒中缠绕和堵塞;对关键部件(螺杆、弯齿和凹板筛等)进行了设计与计算。以晾晒3~5d的辽宁主栽花生品种“花育30”为试验材料,以弯齿与滚筒母线夹角、弯齿弯角和螺杆与滚筒母线夹角为试验因素,以摘净率和破碎率为试验指标,运用回归正交旋转试验方法,对样机进行了两段收获条件下的摘果性能试验;建立试验因素与试验指标之间的数学模型并进行响应面优化试验分析,结果表明:在弯齿与滚筒母线夹角为33°、弯齿弯角为60°和螺杆与滚筒母线夹角为23°时,花生摘果综合指标最优,花生摘净率为98.96%,花生破碎率为0.88%,均优于行业标准,满足实际生产要求。

Abstract:In view of the existing peanut picking device widespreadly used, which breaking rate is high, easy winding, and blocking, based on two-stage peanut harvest, this research studied the mechanisms of picking peanut pods during picking up and threshing, and determined the optimal parameters of picking device. An axial flow peanut picking device with screw bending tooth was designed. The screw, bending tooth and concave sieve worked together to separate peanut pods from plant, because screw possessed pitch angle and bending tooth possessed elevation angle, plant in a circular and axial motion along the roller and then it was eliminated from the machine, which can keep high picking rate, low breaking rate, and avoid winding and blocking. The key components were designed and calculated. Introducing the structure and principle of operation of the machine, the key components’ parameters were confirmed by deeply theoretical analysis which made up the picking mechanism that had a great influence on picking effect. The peanut variety “Huayu 30” was selected as test material, and picking gap, feed quantity and rotating speed of cylinder were selected as experimental factors. Meanwhile, the peanut picking and breaking rate were selected as experimental indexes. Through orthogonal test, the mathematical model was established between the experimental factors and indexes and studied on the response surface optimization. The working parameters of picking performance were optimized. After verification test, the conclusion was obtained that the peanut picking rate was 98.96%, the peanut breaking rate was 0.88%. When the angle between bending tooth and roller generatrix was 33°, the angle of bending tooth was 60°, the angle between screw and roller generatrix was 23°, which met national standard and the need of production.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
