Description

Visual comb-tooth type continuous picking head and picking machine

Technical Field

The utility model relates to the technical field of mechanical picking, in particular to a visual comb-tooth type continuous picking head and a picking machine.

Background

The pepper can be eaten, can be used as spice or can be used as medicine, is a good economic tree species and is widely planted in China. Because the peppers are relatively delicate, the quality is affected by color change due to slight extrusion, and the picking of the peppers is still mainly performed manually at present in order to ensure the quality of the picking of the peppers. However, the pepper fruits are smaller, the branches are larger, and the stems and the small branches are provided with short thorns, so that the manual picking is difficult and the strength is high. In recent years, the workers who pick peppers are difficult to find, the labor cost is increased year by year, and the efficiency of manual picking is not high, so that the actual economic benefit of pepper planting is seriously affected, and the development of the pepper industry is seriously restricted.

In order to solve the problem of difficult picking in the industrialized development of pepper and similar small fruits, related personnel at home and abroad make many efforts and have achieved some results in the research and design of picking machines. The literature of the research on the Chinese prickly ash picking method and the picking tool indicates that the foreign Chinese prickly ash picking method is a mechanical vibration method and a negative pressure siphon method. The mechanical vibration method adopts a large manipulator to clamp the base part of the tree branch, shakes, and shakes and collects the pepper spike from the pepper tree through resonance. The negative pressure siphon method aims at mature fruit branches by using a suction pipe, and the fruits are sucked into a fruit storage box by using a large-scale power machine to generate strong negative pressure air flow. Both methods are relatively violent, and violent picking can cause certain damage to the zanthoxylum bungeanum tree, and the oil pocket and the pepper embryo of the zanthoxylum bungeanum can be possibly damaged, so that the yield in the coming year is affected. The Chinese is used as a Chinese for planting the peppers, the design of a plurality of peppers picking heads is mainly developed from the direction of solving violent picking, and the literature of the current situation and development trend of the handheld peppers picking machine considers that the picking heads can be basically divided into three categories of saw teeth, scissors and rotation according to the working principle. The saw tooth picking head adopts a mode that a fixed blade is combined with a single or a plurality of movable blades, the blade is provided with saw teeth, the fixed blade is fixed, and the movable blade is driven by a motor to do reciprocating linear motion to cut a prickly ash handle. The scissor type picking head simulates the action of scissors to shear the pepper handle. The rotary picking head is driven by a motor to rotate by a circular saw or a salix leaf type blade, and stretches into the root of the prickly ash to cut the prickly ash. The picking heads solve the problem of violent picking well, but have the problem of picking accuracy, when the picking speed is too high, leaves are easy to bring in, so that the quantity of leaves in picked fruits is relatively large, the picking quality is influenced, in the actual operation process, in order to ensure the picking quality of the peppers, only the speed can be sacrificed, and the picking efficiency is still not ideal.

The number of the synchronizing bars 3 is equal to the number of the comb-shaped picking members 6.

Referring to fig. 3 and fig. 4, as a preferred solution, further: the outer sides of the transmission gears 9 are respectively provided with a fixed ring 4; the fixed ring 4 is fixedly connected with the shell 12, and an annular groove is formed in the inner side of the fixed ring to accommodate a limiting rotating shaft 91 on the outer side face of the transmission gear 9, and the transmission gear 9 is limited.
