Description

Leaf branch cutting mechanism and mulberry leaf picking equipment with same

Technical Field

The invention relates to the field of agricultural machinery, in particular to a leaf and branch cutting mechanism and mulberry leaf picking equipment with the same.

Background

At present, when farmers pick mulberry leaves and feed silkworms in mulberry silkworm areas in south China, most of the mulberry leaves are picked from mulberry branches of mulberry trees manually in a mulberry field, so that the method is labor-consuming, time-consuming, slow in speed and low in benefit.

Chinese utility model patent with publication number CN209462951U discloses a device is picked to folium mori, its tooth cover can be for interior tooth cover do shearing movement realize that the folium mori stem stalk is cuted, convenient operation, it is efficient, however, it in the use, still has following defect: (1) according to the mulberry leaf picking device, the spring connected between the outer gear sleeve and the picking device base is adopted for resetting, the outer gear sleeve can only do intermittent forward and backward rotation movement relative to the inner gear sleeve under the limitation of the spring structure, the effective cutting movement is less, and the cutting efficiency in unit time is not high; (2) the outer gear sleeve makes intermittent forward and backward rotation movement relative to the inner gear sleeve, and the outer gear sleeve cannot continuously rotate and cannot perform circumferential cutting, so that the leaf stalks corresponding to the notch of the inner gear sleeve cannot be cut and the cutting is incomplete; (3) the mulberry leaf picking device is influenced by the reciprocating motion of the transmission system, and the outer gear sleeve reciprocates relative to the inner gear sleeve, so that the device per se generates larger vibration, impact, noise and local abrasion, and the service life of the machine and the health of an operator are influenced. (4) Leaf collecting plates are symmetrically and fixedly arranged on the inner sides of the door frames, however, when the leaf collecting plates are adopted to collect the mulberry leaves, the mulberry leaves are easy to fall off from the leaf collecting plates in the moving process of the device, and after the leaf collecting plates are fully piled with the mulberry leaves, the mulberry leaves on the leaf collecting plates are placed in collecting bags for storage, so that the use is troublesome; (5) the picking device is arranged on the first linear motion mechanism, and can only move up and down under the driving of the first linear motion mechanism when in use, the extension directions of the mulberry branches growing on the mulberry trees are different, the picking device is arranged on the first linear motion mechanism, so that the notches of the inner gear sleeves of the picking device can not be adjusted according to the growth direction of the mulberry branches, the mulberry branches need to be manually bent at a large angle to be placed into the picking device from the notches of the inner gear sleeves, the mulberry branches are easily damaged, and adverse effects are brought to the subsequent growth of the mulberry branches.

The Chinese patent application with publication number CN111527878A discloses a novel mulberry leaf picking mechanism and a hand-held mulberry leaf picking device, wherein a driving wheel is driven to rotate by a driving shaft, so that a movable cutter component is driven to rotate around the axis of a fixed cutter component. It realizes the automatic counterpoint of cutting unit through the effect of magnetic force, need not to set up reset structure such as spring, consequently, has realized moving the continuous rotation of sword subassembly around the stationary knife subassembly axis, makes the cutting more comprehensive, and the cutting is efficient in the unit interval, and can reduce vibrations, impact, noise and the local wear that device itself produced. However, it also has the following problems in use: (1) its stationary knife subassembly includes articulated left stationary knife piece and right stationary knife piece, adopt the handle to rotate left stationary knife piece and right stationary knife piece and open the opening that makes the ramulus mori business turn over, it is when using, need move the position that the junction of the adjacent cutting unit of sword subassembly aligns left stationary knife piece and right stationary knife piece strictly and forms the opening part, just can open the opening that makes the ramulus mori business turn over on the stationary knife subassembly, however, adopt the effect of magnetic force to enable the automatic counterpoint of cutting unit, but the counterpoint precision is lower, in using, often need the manual rotation reset handle in order to adjust the position of adjacent cutting unit junction, make the junction of two adjacent cutting units corresponding with the position of opening part, just can open stationary knife subassembly and movable subassembly, it is more troublesome to use. (2) The reset of the movable cutter component needs to be carried out after the driving wheel stops rotating every time, so that the driving devices such as the motor for driving the driving wheel need to be closed before resetting every time, then the driving devices such as the motor for driving the driving wheel need to be opened again when picking next time, and the driving devices such as the motor are frequently started and have larger power consumption compared with the stable operation in the same time. (3) When the reset handle is manually rotated to adjust the position of the joint of adjacent cutting units, an operator needs to observe the rotating position of the movable blade while rotating the reset handle, so that the operator needs to keep high concentration of spirit to observe the position of the movable blade assembly, and fatigue is easily caused.
