Air negative pressure differential tool bit leaf harvester

Abstract

The invention discloses an air negative pressure differential tool bit leaf harvester. The harvester comprises a tubular nose, a collecting tank, a negative pressure machine, corrugated pipelines, a support pipe and a trolley. The leaf harvester adopts air negative pressure transmission driving and the differential rotation of multi-group cutting blades of the tubular nose is realized, thereby repeatedly cutting leaves to obtain small leaf fragments. The cut leaf fragments are collected and processed. The harvester can be used for harvesting leaves and tender branches and buds of broussonetia papyrifera in a large space range, also can be widely applied to pruning of jungles and shrubs in the field of landscaping, and integrates harvesting, pruning and collecting and processing, so that the labor intensity is greatly reduced, and the working efficiency is improved.

Description

[0001] technical field [0002] The invention relates to an air negative pressure leaf harvester, in particular to a differential-speed leaf harvesting cutter head, which is widely used in the harvesting and collection of forage leaves of trees such as eucalyptus glabra, as well as the pruning of horticultural jungles and shrubs, and belongs to the field of agricultural and forestry machinery . [0003] Background technique [0004] Guangyechu is a variety of the genus Moraceae that has been selected and bred from wild paper mulberry in Japan in recent years. Its bark and trunk are high-quality paper-making raw materials; its leaves are fodder and rich in nutrition. According to the measurement, the crude protein content of the leaves of Mulan glabra is 23.48% (twice that of bran), and contains trace elements such as copper, iron, zinc, manganese, etc. It is a high-quality feed for animals and fish. [0005] Planting glabra is a short, flat and fast project for rural pros...

Problems solved by technology

[0008] In the field of landscaping, most of the pruning of horticultural jungles and shrubs also use simple hand-held tools; the pruning of taller trees also requires the operator to use auxiliary devices such as ladders; the pruned leaves or twigs are scattered on the ground, It is not easy to collect and handle, and the pruning efficiency is low

For example, the Chinese invention patent "Horticultural Pruning Machine" (ZL200410002699.1) discloses a gardening pruning machine for trimming shrub branches. Driven by the impeller, the invention throws the broken branches and leaves out of the outlet of the cutter head cover and enters the collection box. , although the work efficiency is improved compared with manual work, the two transmission wheels of the invention are connected by a transmission belt. The transmission load capacity of the belt is poor, and it is easy to slip and idle when trimming wet leaves. Higher plant pruning, and a single blade cannot determine complete cutting; the pruning machine disclosed in the Chinese invention patent "Water Spraying, Flower Pruning Electric Vehicle" (ZL200910161625.5) is driven by a DC motor, and integrates pruning, blowing, water spraying, etc. Planting functions in one, but the pruned branches and leaves scattered on the ground need to be cleaned again manually, which is inefficient
