Fresh corn harvester

Abstract

A fresh corn harvester comprises a chassis assembly, a harvesting assembly, a conveying assembly, an aggregate assembly, a steering assembly and a driving assembly, wherein the harvesting assembly, the steering assembly and the aggregate assembly are sequentially arranged on the chassis assembly, the conveying assembly is arranged on the chassis assembly in a crossing way, the driving assembly provides driving force for the mechanical movements of the whole harvester, the harvesting assembly is used for harvesting clusters and stems of the corn, and the conveying assembly is used for respectively and independently conveying the whole corn plants, the harvested corn clusters and the harvested corn stems to the aggregate assembly. Compared with the prior art, the harvester is specially suitable for Chinese fresh corn planting environment, not only are the functions of harvesting both the stems and the clusters are achieved, but also the harvester can be used for harvesting in opposite rows without manual assistance, and can be used for full-automatic harvesting and collecting, so that the cost is reduced; in addition, the fresh corn harvester reduces the cluster damage rate, increases the recovery total amount of stems and improves the income.

Description

[0001] This case is a divisional application of 2015109539765. technical field [0002] 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 [0003] Grain corn harvesting is to use machinery to complete multiple operations such as ear picking, stacking, and stalk return to the field at one time after the corn wax is cooked. The difference between fresh corn harvesting and grain corn harvesting is that fresh corn harvesting is done in corn milk. Harvested when ripe. [0004] According to reports, my country's grain corn harvesting technology has become mature, and its main process is: use a grain corn harvester to pick ears under the corn growth state (called standing stalk picking), and use the ear picking rollers and ear picking boards to pick ears. Under the action, the ear stalk is pulled off. The cutter cuts the straw from the root an...

AI Technical Summary

Problems solved by technology

These fields have high requirements for corn harvesting machines, which usually need to climb over ditches, climb slopes, and perform misaligned harvesting. However, the large and small fresh corn harvesting equipment sold on the market can not meet the needs of misaligned harvesting, and their harvesting The method has defects such as easy to trap the car, large turning radius, low harvesting efficiency, high grounding specific pressure, easy to collapse the land and cause deep pits and water accumulation, thereby destroying the farmland and resulting in crop production reduction and other defects

[0008] 2. It does not have the function of harvesting both stems and ears

However, although the fresh corn harvesters on the market can cut corn stalks, they do not have the function of harvesting both stems and ears. The machine can only cut off corn stalks and discard them in the field. Straw can also be used as fertilizer for returning to the field. However, when fresh corn is harvested, the water content of corn stalks is often too high to be used as fertilizer. It needs to be manually recycled and then processed. It is extremely difficult to use it for other purposes. Inconvenient and cost prohibitive

In addition, even if there is a machine with the function of harvesting both stems and ears, the corn stalks harvested by the machine need to be pulled to a special processing site for cutting, which is very troublesome

[0010] 3. The ear damage rate is high

[0011] The main principle of grain corn harvesting is to pull down the ear stalks under the action of ear picking rollers and ear picking boards. It is necessary to rely on strong pulling pair of rollers to separate ear and stem. The corn harvesting method 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. Therefore, the acceptance of the above-mentioned corn harvesters by farmers is low, and grain corn harvesters are completely unsuitable. Harvested in fresh corn

[0012] 4. Low degree of mechanization

[0014] 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
