A field harvesting variable-amplitude conveying device

Abstract

The invention relates to the technical field of crop harvesting machinery, in particular to a field harvesting amplitude-changing conveying device. The harvesting of crops should be completed in a short time, and the existing harvesting equipment is inefficient, time-consuming and labor-intensive. The invention includes a power device, a frame, a retractable mechanism, a support frame, and a conveyor belt; a support frame is respectively arranged on both sides of the frame, and the support frame is connected with the frame through the retractable mechanism; the outer sides of the two support frames are respectively equipped with multiple stages Conveyor belts connected head to tail; inner conveyor belt drive roller shafts are connected to power devices; power transmission mechanisms and angle adjustment mechanisms are installed between conveyor belts at all levels. Beneficial effects of the present invention: the width of the conveying mechanism is increased, multi-row crops can be harvested at the same time, and the vegetables are continuously transported to the frame for sorting and boxing, which improves the harvesting efficiency and reduces labor intensity and operation. Low cost, the unfolded width of the conveyor belt can be adjusted according to needs, and it is easy to use.

Description

technical field [0001] The invention relates to the technical field of crop harvesting machinery, in particular to a field harvesting amplitude-changing conveying device. Background technique [0002] The growth process of crops is greatly affected by time and season, especially for vegetables with strong seasonality, the production and harvest of which are more obviously affected by climate change, time, customer requirements, etc., and need to be harvested in a short period of time Once the picking period is over, the quality and shelf life of vegetables will decline, affecting product prices. In addition, in case of sudden changes in weather such as rainfall and temperature drop, the picking operation must be completed within a limited time. At present, vegetables and other crops are harvested mostly by manual picking and trucked out of the vegetable field.

[0002] The growth process of crops is greatly affected by time and season, especially for vegetables with strong seasonality, the production and harvest of which are more obviously affected by climate change, time, customer requirements, etc., and need to be harvested in a short period of time Once the picking period is over, the quality and shelf life of vegetables will decline, affecting product prices

In addition, in case of sudden changes in weather such as rainfall and temperature drop, the picking operation must be completed within a limited time

At present, vegetables and other crops are harvested mostly by manual picking and trucked out of the vegetable field. Due to the limited width of the harvesting vehicle, every time the harvesting vehicle passes through the vegetable field, usually only 2 ~ The crops in 3 rows (ridges) are picked and transported, but the harvesters who are far away from the car still need to rely on manual handling to load the vegetables or directly move them out of the vegetable field; the labor intensity is high, and the harvesting efficiency is extremely low, which cannot meet the harvesting operation It not only wastes a lot of manpower and time, but also increases the cost of harvesting operations, and some vegetable crops also exceed the harvesting period due to low picking efficiency, resulting in a decline in the quality of agricultural products, which further affects their storage time and sales.
