Stem and spike harvesting fresh maize harvester

Abstract

The invention provides a stem and spike harvesting fresh maize harvester which comprises a chassis assembly, a harvesting assembly, a transfer assembly, an aggregate assembly, a driving assembly and adriving assembly, wherein the harvesting assembly, the driving assembly and the aggregate assembly are successively arranged on the chassis assembly; the transfer assembly bestrides the chassis assembly, the driving assembly provides power drive to mechanical movement of the whole harvester, the harvesting assembly is used for harvesting spikes and stems of maize, and the transfer assembly is used for transferring whole maize, harvested maize spikes and maize stems to the aggregate assembly independently. Compared with the prior art, the harvester is specially applicable to a Chinese fresh maize planting environment, not only has the stem and spike harvesting function, but also can carry out non-row-controlled harvesting without manual assistance, and has the function of harvesting and collecting maize full-automatically, so that the cost is lowered. In addition, the stem and spike harvesting fresh maize harvester reduces the damage rate of stems and spikes, improves the recovery total amount of stems and increases the income.

Description

[0001] This case is a divisional application of 2015109563745. 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
