Fresh corn harvester

Abstract

The invention provides a fresh corn harvester, which includes a frame assembly, a header assembly, a transmission assembly, a granary assembly, a driving assembly and a driving assembly. Among them, the header assembly, transmission assembly, driving assembly, granary assembly and drive assembly are connected to the frame assembly; the header assembly and the granary assembly are located at both ends of the transmission assembly, and the driving assembly and The drive assembly provides power to drive the entire machine. Compared with the existing technology, the fresh corn harvester of the present invention realizes the excellent functions of harvesting corn ears without damage, less damage to farmland, efficient harvesting without rows, and harvesting both stems and ears, and realizes the full mechanization of fresh corn. Damage-free harvesting fills a major gap in the field of fresh corn harvesting.

Description

technical field [0001] The invention relates to automatic agricultural machinery equipment, in particular to a fresh corn harvester, in particular to a fully automatic stem and ear harvester. Background technique [0002] Corn is divided into three categories: grain corn, silage corn, and fresh corn. Grain corn is our most common common corn. It mainly harvests the ear grains after waxing (when the moisture content is the lowest). It can be used as grain in lean years and as feed or wine making raw materials in good years. Straw is used as fuel, returned to the field or yellow storage After that, it is used to feed livestock; silage corn is mainly harvested from the whole crop in the late stage of milk ripening, and the ears and stalks are crushed together and then stored and fermented, and used as animal husbandry feed; while fresh corn is similar to fruit, and its ears are in the early stage of milk ripening Harvested (when the moisture content is the highest), it is main...

AI Technical Summary

Problems solved by technology

[0006] The main principle of grain corn harvesting is that after the corn is cooked with wax, the ear stalks are pulled down by the action of the picking roller and the ear picking board, and the ears and stalks need to be separated by the strong pulling pair of rollers. , the water content is very high, and the pull-down pair of rollers for grain corn harvesting is very easy to damage the grains at the bottom of the ears that are in contact with the stalks, and the ear damage rate is too high, so farmers have low acceptance of the above-mentioned corn harvesters. Grain corn harvesters are totally unsuitable for fresh corn harvesting

[0007] 2. Foreign machinery is not suitable for the planting environment of China's fresh corn production areas

[0008] U.S. Patent US2014 / 0059994 A1 discloses a fresh corn harvester. The fresh corn harvester is specially designed for the concentrated contiguous large-area dryland in the United States. With a weight of one ton and a fuselage nearly ten meters long, this type of fresh corn harvester is mainly manufactured by the American company Oxbo. The cost is high, and the price is more than two million yuan. For ordinary farmers in our country, the cost is extremely high and unaffordable. At present, it is only used in China Green Group's super large fresh corn planting base

[0009] At present, there is no formed fresh corn harvester for sale in the domestic market, because the fresh corn production areas in my country mainly have the following planting environments: small flat land or slope land without furrows, and wet, soft and easy-to-sink land with furrows. Paddy field

These fields have high requirements for corn harvesting machines, which usually need to climb over ditches, climb slopes, and perform wrong-row harvesting. There are many defects such as easy to trap cars, large turning radius, low harvesting efficiency, high grounding specific pressure, easy to sink the land, cause deep pits to accumulate water, destroy the moisture content of the farmland, and lead to crop production reduction, etc.

[0010] 3. It does not have the function of harvesting both stems and ears

However, the only fresh corn harvester on the market does not have the function of harvesting both stems and ears. The machine can only cut off the corn stalks. The rolling of the machine not only requires manual picking, but also is difficult to recycle. After recycling, manual field handling, bundling, loading, and subsequent crushing processing are required, which is extremely inconvenient and time-consuming. During this complicated process, the straw evaporates and loses water, resulting in yield and economic losses. The superiority of machinery replacing manual labor to complete the whole harvesting process with high efficiency cannot be realized, and the market promotion prospect is poor.

[0012] 4. Low degree of mechanization

[0016] Based on the above technical problems, it can be seen that the mechanized harvesting technology of fresh corn in my country has not yet started, and it has become a bottleneck that seriously restricts the development of the fresh corn industry; The development of technologies such as simultaneous harvesting, non-aligned harvesting, harvesting without damage to ears, and removal of impurities on ears has special practical significance. Therefore, it has become a top priority to break through the mechanization of fresh corn harvesting
