Description

Technical Field

[0001] The utility model relates to the technical field of leaf cleaning equipment, in particular to a leaf suction and crushing device for a sweeper. Background Art

[0002] A sweeper is an efficient and environmentally friendly cleaning device used to clean leaves and other debris on the ground. It can quickly collect leaves and other garbage into the trash can to restore the ground to a clean state. The sweeper not only improves cleaning efficiency, but also reduces the labor intensity of manual cleaning. Compared with traditional manual cleaning, the sweeper can complete the cleaning task more quickly;

[0003] When cleaning and collecting leaves, the existing sweeper can only realize a suction and collection function of leaves, and cannot realize a function of collecting and crushing leaves, thereby failing to improve the amount of leaves collected by the sweeper. Therefore, the existing Chinese utility model patent disclosed by the publication number CN210965389U: a leaf suction and crushing device for a sweeper, the application can be equipped with different numbers of blades according to the leaf crushing effect, and the distance between the blades can be flexibly adjusted, which is suitable for cutting different kinds of leaves, so as to improve the leaf crushing effect. Although the adjustable blades are set in the application to crush different kinds of leaves, The leaves are crushed by the blades, but the blades are generally made of metal, and the sweeper will suck in other debris when sucking in the leaves, and the crushing blades inside the sweeper are usually designed for these lightweight objects. When the sweeper sucks in hard objects such as stones or metal blocks, these objects will collide violently with the blades. Since the hardness of stones and metal blocks is much higher than the designed bearing range of the blades, this collision will cause the blades to be subjected to great impact and wear. Over time, the blades may break, deform or wear excessively, thereby losing the function of crushing the leaves, and may even cause damage to other parts of the sweeper. Utility Model Content

A plurality of dispersion rods 17 are fixedly installed at the lower end of the collecting cover 9, and the dispersion rods 17 are inclined thirty degrees to the top center position of the collecting cover 9. When the collecting cover 9 is in When the buffer cylinder 5 rotates, the leaves accumulated at the bottom of the buffer cylinder 5 can be scattered, which is convenient for being sucked into the crushing box 3 for crushing. A fixed shaft 18 is rotatably installed at the center position of the impeller 12, and a plurality of mounting rods 19 are fixedly installed on the upper end of the fixed shaft 18. The end of the mounting rod 19 away from the fixed shaft 18 is fixedly installed on the inner side of the collecting cover 9 by screws.
