Corn harvesting machine

Abstract

The invention discloses a corn harvesting machine. A spike picking mechanism is mounted at the front part of a stander, a straw crushing mechanism is arranged below the rear part of the spike pickingmechanism, a lifting mechanism is arranged on the left side of the rear part of the spike picking mechanism and is obliquely arranged in a front-low and rear-high manner, and a peeling mechanism is arranged below the rear part of a high end of the lifting mechanism; and a guiding plate is arranged between the spike picking mechanism and the lifting mechanism and is obliquely distributed in a left-low and right-high manner, a lower end of the guiding plate is supported by a top rod, and the top rod can alternately move up and down under the action of a driving mechanism. According to the corn harvesting machine, baby corns are guided into the lifting mechanism through an eccentric vibration device, so that a blocking phenomenon is effectively avoided; the corns are conveyed from a horizontal manner to a stereoscopic manner, so that the conveying is convenient and rapid; and meanwhile, the injury of the corns caused due to the contact with a spike picking roll can be prevented, and straws can be adequately and integrally crushed at a relatively low rotation speed. The corn harvesting machine is simple and compact in complete machine structure, occupies a small space and is beneficialto the development of a complete machine to the direction of miniaturization.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a corn harvester. Background technique [0002] The corn harvester is an operating machine that uses machinery to complete corn stalk cutting, ear picking, peeling, threshing, straw treatment, and even rotary plowing of the land after harvesting when the corn is mature, according to its planting method and agronomic requirements. The deficiency that existing corn harvester exists is: [0003] 1) After the baby corn is taken off, the method adopted is to dial the baby corn into the lifting channel through a circular chain mechanism. This method can only be translated, which takes up a lot of space and the mechanism is bloated, which will increase the volume of the whole machine and lift The entrance of the channel is relatively narrow, and the baby corn is easy to block at the entrance. On the one hand, it will affect the efficiency of the corn harveste...

Problems solved by technology

[0003] 1) After the baby corn is taken off, the method adopted is to dial the baby corn into the lifting channel through a circular chain mechanism. This method can only be translated, which takes up a lot of space and the mechanism is bloated, which will increase the volume of the whole machine and lift The entrance of the channel is relatively narrow, and the baby corn is easy to block at the entrance. On the one hand, it will affect the efficiency of the corn harvester. On the other hand, the baby corn, especially the tender corn, is easy to cause scratches at the entrance of the lifting channel.

[0004] 2) When the existing corn harvester picks the baby corn, the corn stalk is directly pulled down by the ear-picking roller and then the baby corn is pulled off, which will cause the baby corn to directly contact the high-speed rotating ear-picking roller, thereby damaging the baby corn. Especially tender corn, the damage is particularly serious

[0005] 3) Stem pulling knife is a plurality of diameter cutting blades evenly distributed on the circumference of the stem pulling roller. The position of the diameter cutting blade relative to the stem pulling roller is fixed, that is, the two closest diameter cutting blades on the two stem pulling rollers The gap cannot be adjusted, and its axis is horizontal and parallel to the right, so it cannot adapt to the diameter change of corn stalks of different varieties and under the condition of not passing through the soil. The adaptability of thick corn stalks and slender corn stalks is poor, and there is no ear picking knife Cooperate, which will easily cause damage to the baby corn that has been removed from the stalk

[0006] 4) The stubble removal (that is, breaking the corn stalks back to the field) assembly on the existing corn harvester directly interrupts the corn stalks by the high-speed rotating straight knife for stubble removal, but because of its high speed and straight knife, the straw after stubble removal It is long, consumes a lot of power and takes up a lot of space, and is only suitable for large-scale plain corn harvesting

No matter what kind of steering structure is used, the existing technology has the disadvantages of large volume, complex structure and high cost.

[0008] 6) The corn harvester adopts the "pressure feeding" method when peeling, that is, a set of pressure feeding device is installed above the peeling roller, so that the corn is conveyed forward while pressing the peeling roller, so that the whole peeling mechanism occupies The space is large, which is not conducive to the development of the whole machine in the direction of miniaturization, and the angle of the peeling roller at the front and rear ends of the axial direction cannot be adjusted, which is difficult to meet the actual needs
