The invention discloses a leaf collecting device. The leaf collecting device comprises a shell body, an air inlet and an air outlet which are formed in the shell body, a collecting box detachably connected to the lower part of the shell body, an air guide channel communicating with the air inlet and the air outlet, and an air inlet power part along in the air guide channel; and further comprises apre-screening device arranged on the lower part of the air guide channel, and a secondary screening device arranged on the side part of the pre-screening device. According to the leaf collecting device, leaves and sand soil are preliminarily separated by the pre-screening device, then the leaves and the sand soil are further separated by the secondary screening device, the collected leaves are effectively subjected to sand-leaf separation, cleaner leaves are obtained, the quality of a fertilizer made from the leaves in the later stage is improved, and meanwhile the cost of manual screening isalso reduced.
本发明公开了一种树叶收集设备，包括壳体、设于壳体上的进风口和出风口、可拆卸的连接于壳体下部的收集箱、连通所述进风口和出风口的导风通道、沿于所述导风通道内的进风动力部件；还包括设于所述导风通道下方的预筛选装置、设于预筛选装置侧部的二级筛选装置；本发明利用预筛选装置将树叶和沙土进行初步分离，再利用二级筛选装置将树叶和沙土进行进一步的分离，有效的将收集进来的树叶进行沙叶分离，得到更干净的树叶，提高了后期用树叶制作出化肥的质量同时也减小了人工筛选的成本。
