Self-propelled corn harvesting machine

Abstract

The invention discloses a self-propelled corn harvesting machine. A cornstalk collector, a soil remover and a bundling machine are arranged behind a header of the harvesting machine in sequence, and the cornstalk collector and the bundling machine are in power connection with a power device of the harvesting machine; the soil remover is provided with a screen drum which is fixedly connected with a machine frame through a support, a feed inlet in one end of the screen drum is communicated with a discharge outlet of the cornstalk collector through a feeding pipeline, and a discharge outlet in the other end of the screen drum corresponds to a feed inlet of the bundling machine; a shaft lever is installed in the screen drum, screw blades are fixedly connected to the shaft lever, the two ends of the shaft lever are connected to the screen drum in a rotary mode, and the shaft lever is in power connection with the power output end of the power device through a power transmission mechanism; the power input end of the cornstalk collector and the power input end of the bundling machine are in power connection with the power device through power transmission mechanisms respectively. By the adoption of the self-propelled corn harvesting machine, corn ears and cornstalks can be collected at the same time, soil in cornstalk fragments can be screened out through the soil remover, and economic benefits of farmers can be increased after baled cornstalks are sold.

Description

Technical field [0001] The invention relates to a self-propelled agricultural machine tool, in particular to a self-propelled corn harvester. Background technique [0002] In the past, after the ears of corn were harvested mechanically, the stalks of corn would remain in the field, and the stalks needed to be removed to prevent it from affecting re-seeding. Since the stalks have a certain utility value, returning them to the field after being crushed can be used as organic fertilizer. Too much crushed straw will affect the growth of crops, so the demand for crushing and returning straw to the field is not enough to treat all the straw in the field. With the development and utilization of straw, the straw can be sold to power plants for power generation or to factories to process ethanol and fertilizer. However, it is required to bundle the straw into bundles, which is convenient for transportation and calculation, and limits the soil content in the straw. For baling the straw, yo...

Problems solved by technology

[0002] In the past, after mechanical harvesting of corn ears, the corn stalks would remain in the field, and the stalks had to be removed to prevent their impact on re-sowing. Because the straws have a certain use value, they can be used as organic fertilizers after being crushed and returned to the field. Too much straw crushed material will affect the growth of crops, so the demand for straw crushing and returning to the field is not enough to process all the straw in the field. With the development and utilization of straw, straw can be sold to power plants for power generation or sold to factories for processing ethanol and fertilizer. However, it is required to bundle the straw into bundles, which is convenient for transportation and price calculation, and the soil content in the straw is limited. To bundle the straw, you need to purchase another baler, and it takes manpower to remove the straw. In the harvest season, there is no The extra time and manpower are used to process the straw separately. After weighing the sale price of the straw and the cost of bundling, farmers often choose to burn the straw in the field and turn the straw into plant ash and return it to the field. Although the processing cost is saved, burning the straw will pollute the atmosphere. environment, it is also easy to cause forest fires
