Often a good crop of vegetable crops does not mean a big profit, since the final stage of cultivation of these crops is cleaning, which involves a lot of difficulties. Cleaning should be carried out as quickly as possible, under optimal weather conditions and with minimal losses and damage to products.
Traditionally, harvesting of vegetable crops such as tomatoes, cucumbers, zucchini, eggplants, peppers and melons: watermelon and melon intended for sale in fresh form, is carried out manually with the involvement of a large number of labor.
Manual labor during this operation is quite heavy and unproductive, in addition, the harvested product is often damaged by overloading into a trailer or container. The cost of using labor is also important, because of its increase from year to year. Sometimes the very possibility of attracting workers is a limiting factor in solving these problems.
In this situation, the only possible solution is to mechanize the harvesting of vegetables. There are two solutions here: the use of harvesters or harvesting machines and harvesting conveyors.
The first method of cleaning has the following drawbacks: the high cost of such equipment and often unsuitable for harvesting vegetables for sale in fresh form due to damage, as well as the inability to selectively harvest the ripened fruit, as these machines take away the entire and at the same time all the products from the field.
The second method - the use of harvesting conveyors - ideally solves these problems: minimal product damage, high productivity and the possibility of selective harvesting, as workers themselves determine what fruits should be cleaned.
The construction of conveyors for cleaning is a lateral conveyor belt with a rubber cloth, a frame that is hung on the tractor and the central belt for transporting the product to the trailer. As additional options are provided sorting platforms, tapes or tables.
The principle of operation is as follows: a tractor with a harvesting conveyor and a trailer for the harvested vegetables moves slowly along the field, followed by workers, whose task is to select mature fruits, cut them and shift them to the side belt of the conveyor. After that, the products are automatically moved to the central tape or sorting table and then to the trailer, boxes, containers or boxes.
With this method of harvesting, damage to vegetables is minimal, as they move along special rubber belts of the conveyor and at the end are manually taken by the operator in the trailer. In addition, the speed of the belt can be adjusted.
Harvesting conveyors greatly facilitate the labor of workers, increasing their productivity, engaged in cutting products. They now do not need to load vegetables into buckets or sacks and manually transfer them to a trailer or containers.
Harvesting conveyors have a folding frame, which allows you to translate their transport position, significantly reducing the size. This is important when transporting this equipment on roads, if the fields are at a considerable distance from each other.
The modularity of the design allows the user to order a conveyor that meets almost any requirements when cleaning a certain type of vegetables. In addition, additional options make it possible for the primary processing of products, sorting and packaging.
To equip this equipment requires a wheeled tractor with a rear three-point hitch, hydraulic and electrical systems.
