Self-propelled corn combine harvester in mountain lands

Abstract

The invention relates to a self-propelled corn combine harvester in mountain lands. The self-propelled corn combine harvester in the mountain lands is characterized by comprising a main rack, a cab, a cutting table, a four-wheel drive system, an ear elevator, a peeler and an ear box, wherein the cutting table is positioned at the front of the main rack; the cab is positioned at the rear of the cutting table; the ear box is a self-discharging backward-turned grain box and is positioned at the rear end of the main rack; the cab is connected with the cutting table through a rotating shaft connecting plate of the cutting table; an electromagnetic clutch is respectively connected with the ear elevator and the cutting table; an air cylinder is positioned on the main rack at the front end of theear box; and the peeler is positioned at the bottom of the cutting table. Compared with the prior art, the self-propelled corn combine harvester in the mountain lands has the following beneficial effects: 1) the cutting table can perform non-opposite-ridge harvesting so as to greatly increase the work efficiency; 2) the four-wheel drive system can control the direction through a front axle so that the driving capability is stronger and the response is more flexible; 3) a cutting knife is arranged without affecting the next operation of the land; and 4) machines and tools enter the land once so as to finish complete corn harvesting operation links such as picking ears, peeling, transporting ears, discharging shelled corns and leaves, collecting ears in a box and the like.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a self-propelled mountain corn combine harvester. Background technique [0002] As a big country of corn production in China, corn harvesting machinery is widely used and has a variety of structure types. The chassis structure includes traction type, semi-suspended type, full-suspended type, etc.; Combination rollers, horizontal claw rollers, horizontal stem pulling rollers plus ear picking boards, etc.; the process of operation is generally ear picking—peeling (or direct loading)—stalk crushing (returning to the field or recovery) or Lay out - fruit ear container or trailer. Its power types include traction type, suspension type (backpack type), self-propelled type and corn header, etc. [0003] The 4TW-2 trailed corn harvester is widely used in production. This model can complete the procedures of ear picking, peeling, and stalk crushing and returning to the field in one...

AI Technical Summary

Problems solved by technology

Because the planting structure of corn in my country varies from region to region, the row spacing varies greatly, which cannot adapt to the complex corn planting situation in China.

[0006] 2. The problem of the balance between road clearing and the unit, most of the fields are responsible, the plots are small, the ground is close to the ground, and the space around the ground is small, so the relative operation is relatively difficult, because the ear picking mechanism and ear collecting devices are placed in the front. The unit is difficult to balance and the body is too long, resulting in inflexible rotation of the whole machine, wasted working time and low work efficiency

[0007] 3. The problem of returning straw to the field

Generally, the self-propelled corn harvester is equipped with a straw returning machine. The disadvantages of this combination are: the power consumption of the main machine increases, the working speed becomes slower, and the efficiency is low, which affects the next sowing.

[0008] 4. Adaptability to hilly and slope farming

In the past, the corn planting land in my country was mainly concentrated on the relatively flat ground, and the hilly land and sloping land made harvesting very difficult

[0009] The existing self-propelled corn harvester walking drive system and working part drive system have complex structures, many transmission links, and poor reliability; the machine tools have poor operating quality, serious blockage, difficult cleaning, low efficiency, and cannot adapt to hills and slopes.

As the core component of corn harvesting machinery, corn ear picking mechanism has low harvest rate, high grain breakage rate and poor working reliability. These problems need to be solved urgently
