Description

Conveying trough of corn harvester

Technical Field

The utility model relates to a maize picker conveyer trough.

Background

The corn harvester is an agricultural machine which uses machinery to complete multiple operations of ear picking, stacking, returning stalks to the field once and the like for the corn once when the corn is ripe. The process flow comprises the following steps: ear picking is carried out by a corn harvester in a corn growth state (called stalk picking), and under the action of an ear picking roller and an ear picking plate, the ear stem is pulled apart. Due to the height difference of the inner and outer picking rollers, the ears fall into the ear box, and the ear box is opened and piled after being filled. The cutter rotating at high speed cuts the straws from the root, then the straws enter the crushing mechanism to be crushed into 3-5CM long fragments, and the crushed straws naturally fall to the ground. Then the ears are transported to the field, peeled by a peeling machine, and threshed after being aired.

According to the planting mode and the agricultural requirements, the machine is used for completing the production links of cutting, picking, peeling, threshing, processing straws, rotary tillage on land after harvesting and the like of the stalks of the corn. In most areas of China, the moisture content of the corn seeds is generally 25% -35% or even higher when the corn is harvested, and the corn cannot be directly threshed when the corn is harvested, so a segmented harvesting method is generally adopted. The first stage of harvesting refers to directly collecting corn ears with bracts or barks and straws after picking the corn ears for processing; the second stage is to air-dry the corn ears in the ground or on the field and then thresh.

The corn harvester is a complete corn harvesting machine which is formed by combining a header, an elevator, a peeler, an ear box, four main mechanism components, a walking chassis serving as a power output system, a control system matched with the four main components and other mechanisms. The elevator is used as a fruit cluster conveying mechanism, and the working efficiency of the elevator also directly influences the harvesting performance of the whole machine. The lift conveyer of the mainstream type in the current market is mostly 300-350 mm in overall thickness, and the height of a lift chain scraper is 60-70 mm, so that the lift conveyer is suitable for areas with high fruit cluster maturity and low straw harvest. The harvested fruit cluster has low maturity, and the moisture content of the straws is generally between 70 and 80 percent in areas with higher maize straws, particularly Xiangyang and other areas in Hubei. In addition, plants are densely planted, the stalks are high, the plants are easily pushed down or broken in the harvesting process of the corn harvesting machinery, the phenomenon of blockage of an elevator is easily caused, and the harvesting efficiency is influenced.

The utility model has the following contents:

the utility model aims at solving the defects of the prior art and providing a conveying trough of a corn harvester.

In order to ensure that the scraper can be stably fixed on the lifting chain, the lifting chain scraper comprises a scraper and two supporting legs, the two supporting legs are respectively arranged at two ends of the bottom of the scraper, and the scraper is fixed on the first lifting chain and the second lifting chain through the two supporting legs at the bottom of the scraper.

In order to clean sundries, prevent the channel from being blocked and increase the workload of the machine, the machine also comprises a sundry cleaning fan which is positioned at the front end of the lifting conveyor.

Has the beneficial effects that:

the existing main stream type elevator has the overall thickness of 300-350 mm mostly, and the height of an elevating chain scraper is 60-70 mm, so that the elevator is suitable for areas where the harvest fruit cluster maturity is high and the straw is low. The harvested fruit cluster has low maturity, and the moisture content of the straws is generally between 70 and 80 percent in areas with higher maize straws, particularly Xiangyang and other areas in Hubei. In addition, plants are densely planted, the stems are high, and the corn harvesting machinery is easy to push or break the plants in the harvesting process, so that the phenomenon of blockage of an elevator is easy to occur, and the harvesting efficiency is influenced;

and the utility model discloses improved this size, whole thickness with the elevator has increased 420mm to 450mm, the height of lift chain scraper blade has increased to between 100mm to 150mm, the degree of depth with the lift groove has increased to between 180mm to 220mm, can guarantee like this that can not push away the rupture with corn plant at the in-process of reaping, also guarantee that the crop can not fall out the elevator, lead to the elevator jam, the conveying capacity of ear elevator has been strengthened simultaneously, harvester elevator's adaptability when having guaranteed the different regional crops of results.
