Design and fabrication of a tractor powered leaves collector machine equipped with suction-blower system

摘要

Leaves scattered on the parks, passages, and other places have a detrimental effect on the beauty of the environment, and decrease photosynthesis, hence, the efficiency of plants. Leaves are also used in the production of peat. This makes using leaves collectors in parks, and organizations with a green space useful. Due to the fact that leaves take up a high volume, their transportation is difficult. Using the machine introduced in this paper which was equipped with a suction-blower system, increases efficiency, and at the same time decreases the costs of green space, and their workforce cost. Focusing on overcoming the mentioned difficulties, this study was carried out in order to design and produce a tractor powered leaves collector equipped with suction-blower system. Various designs were studied and based on their advantages and disadvantages, the best design was selected. The initial modeling was carried out using the engineering software of SolidWorks. After designing different parts of the machine, such as the chassis, transmission system, the tank, handling system, suction-blower system, they were analyzed. Furthermore, the effects of pump suction duration, the length of suction pipe, and different intervals of PTO on the system's performance were studied. The required power for various parts of the system was calculated. The overall power consumption of the system was calculated to be 18,392 W which amounts to 25 hp.
