Embodiment Construction

[0033] Such as Figure 1 to Figure 11 As shown, in view of existing defects, the subject of protection of this patent is as follows:

[0034] What was developed was a corn plant leaf picker, a machine that removes 3-4 leaves from the ground above the corn plant.

[0035] The basic principle is that it has the function of walking between rows of corn, and removes corn below a certain height during the walking process. The removal operation is carried out in a continuous and flexible tearing manner.

[0036] Based on the above description, it is first necessary to remove the three corn leaves at the lower part of the corn plant without affecting the upper corn leaves, and recycle the removed corn leaves. In terms of power, diesel engines are given priority for driving. It also has the function of assisting power for walking. According to the difference in plant row spacing and the difference in leaf height between different varieties, it must also have the function of adjustin...

Abstract

A leaf picking machine for corn plants comprises a traveling part, a leaf picking part and a power part, wherein a rotary disc is mounted above a chassis of the traveling part, a large slewing bearing is arranged between the rotary disc and the chassis, two slide blocks are arranged on the rotary disc, a first bearing pedestal is arranged in the upper part of each slide block, and a rolling bearing is mounted in the first bearing pedestal; a pair of second bearing pedestals is mounted, a main shaft is mounted in the second bearing pedestals, a belt wheel is mounted in the middle of the main shaft, splines are arranged at two ends of the main shaft, and a diesel engine drives the main shaft to rotate through belt drive; one end of a rotary shaft is a spline sleeve while the other end of the rotary shaft is a cutter mounting part, wherein the spline sleeve is slidably matched with the splines in the end part of the main shaft, the middle part of the rotary shaft is fixedly arranged in the first bearing pedestal through a shaft shoulder and a bearing cover, a pair of cutters is mounted at the cutter mounting parts, and rubber strips are arranged in the cutters. The leaf picking machine for corn plants provided by the invention is used for picking three low leaves at the bottom of the corn plants and the picking efficiency is improved.

Description

technical field [0001] The invention relates to tools used in corn planting, in particular to a corn plant leaf picker. Background technique [0002] Corn is the largest food crop in my country. At present, in order to create high yields, the planting density in production has been increasing, from about 2,500 plants per mu in the 1980s to the current 5,000-6,000 plants per mu, and the row spacing is also 75cm in the past. , shrink to 60cm. The increase in density has caused closed canopy in the field and poor ventilation. As a result, the incidence of diseases and insect pests has greatly increased. In particular, the lower three leaves age early and develop early. At the stage of corn powder loosening, these three leaves basically lose their energy production function and consume nutrients. Lesions spread all over the leaves. burden", and is a new "source of disease", becoming the base of secondary infection of germs. Therefore, timely removal of the lower three leaves i...
