A system and implementation method for orderly harvesting of leafy vegetables on the same machine

Abstract

The invention discloses an on-machine binding strip bundling system and a realization method for orderly harvesting of leafy vegetables, and relates to the field of agricultural equipment. Vegetables are pushed to the elastic binding strips under the action of the power of the branch clamping orderly conveying system and the deflector. When the thrust of the leafy vegetables on the elastic binding strips reaches the force required for its elastic deformation, the elastic binding strips pop out from the groove And instantaneous bending deformation bundles the part of the leafy vegetables, and the leafy vegetable bundles lie down on the transverse conveying mechanism along the inclined plane and under the action of gravity and are sent out laterally. The invention realizes rapid bundling of quantitative leaf vegetables through the orderly release and instantaneous bending deformation of the elastic binding strips only relying on the conveying power, the structure and method are simple and reliable, and easy to realize.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to an on-machine tying and bundling system for orderly harvesting of leafy vegetables and an implementation method. Background technique [0002] At present, the planting area of ​​various vegetables is increasing, but the harvest and packaging of leafy vegetables, especially non-heading and bulbous leafy vegetables, has become a major problem faced by vegetable growers. The existing leafy vegetable disorder harvester scheme, the leafy vegetables are disorderly and loose after harvesting; the current research on the leafy vegetable orderly harvester focuses on orderly harvesting and upward transportation, and the discrete throwing after transportation, causing mess Laying, loose loading capacity is limited. The disordered collection after mechanized harvesting creates difficulties for subsequent collection, transportation and processing. Chinese patent (CN204392866U) disclose...

AI Technical Summary

Problems solved by technology

The existing leafy vegetable disorder harvester scheme, the leafy vegetables are disorderly and loose after harvesting; the current research on the leafy vegetable orderly harvester focuses on orderly harvesting and upward transportation, and the discrete throwing after transportation, causing mess Laying, loose load limited

Disorderly collection after mechanized harvesting creates difficulties for subsequent collection, transportation and handling

Chinese patent (CN204392866U) discloses an orderly harvesting and collecting device for leafy vegetables. At the exit after the leafy vegetables are clamped and transported, the leafy vegetables are changed from vertical to flat on the conveyor belt; Chinese patent (CN206585968) proposes a Leafy and vegetable orderly and disorderly universal harvester scheme, through the clamping and conveying method of twisting the conveyor belt, the orderly stacking of leafy vegetables from upright to sideways is realized; the above methods are difficult to change the limited collection load due to looseness At the same time, it is difficult to ensure an orderly effect under the complex ground in the field and the unstable and vibrating conditions of the fuselage

Chinese patent (CN106961919A) proposes a harvester scheme for leafy vegetables, which adopts a four-sided conveyor chain with splints to transport the cut leafy vegetables horizontally, and then transports them to the temporary storage area along the side and falls into the storage bag. The structure of the scheme is complicated, and the horizontal transportation after cutting is difficult and the transportation volume is small

However, the large-scale orderly leafy vegetable harvesters in developed countries add some labor to the body to complete manual binding and collection at the leafy vegetable harvesting and transportation outlets. The labor cost is huge, and it is even more difficult to adapt to small-scale planting and greenhouses. Operational requirements in facilities such as

[0003] At present, the packaging of leafy vegetables is completed in the processing area after harvesting. It needs to go through harvesting, disorderly collection, disorderly transportation, and then orderly and complete processing such as bundling, bagging, and film sealing. The links are complicated and difficult.

The existing automatic binding machines for various types of leafy vegetables are also difficult to meet the needs of the same machine for orderly harvesting of common leafy vegetables such as chicken feathers, celery, leeks, and three-leaf vegetables. The main problems are as follows:

[0004] (1) After orderly harvesting, the leaf vegetables are in a state of continuous clamping and conveying, while the existing automatic bundling machines need to be manually fed into bundles, and the automatic bundling machine only realizes a single action of automatic bundling;

[0005] (2) The existing automatic baler has a complex structure and large size, and it is difficult to realize multi-row synchronous baling of leafy vegetables within the limited body width of the harvester
