Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, in particular to a vertical harvesting platform and a corn harvester having the same. Background Art

[0002] Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and livestock products. Agricultural machinery is a relative concept, referring to the general term for all machinery used in agriculture, animal husbandry, forestry and fishery. Agricultural machinery belongs to the category of agricultural machinery and implements. The promotion of the use of agricultural machinery is called agricultural mechanization. Corn harvesters are needed in the process of corn planting.

[0003] Currently, there are two main types of corn harvesting machinery that can separate corn grains from straw during harvesting. One type is a vertical cutting table with a vertical hay chopper. The disadvantage of this type of corn harvester is that the structural characteristics of the vertical hay chopper limit the maximum working capacity, resulting in the inability to further increase the harvesting speed. The other type is a horizontal cutting table with a horizontal hay chopper. The disadvantage of this type of corn harvester is that the horizontal cutting table has a complex structure, high manufacturing cost, and is inconvenient to maintain. Summary of the Invention

[0004] The object of the present invention is to provide a vertical harvesting platform and a corn harvester having the same, so as to solve the problems of limited harvesting speed of vertical models and complex structure, high manufacturing cost and difficulty in maintenance of horizontal models.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a vertical harvesting platform, comprising a harvesting chain bracket, and further comprising:

[0006] A protective cover arranged on the outside of the reed chain bracket;

[0007] A header assembly is arranged inside the reed chain bracket, the header assembly includes a lower cutter arranged inside the reed chain bracket, a transverse conveyor belt is arranged inside the reed chain bracket, and a clamping chain is arranged inside the reed chain bracket;

[0008] The grass-chopping assembly is arranged on the rear surface of the straw-chopping chain bracket, and the grass-chopping assembly includes a grass-chopping assembly shell, a fixed knife is arranged inside the grass-chopping assembly shell, a movable knife is arranged inside the grass-chopping assembly shell, and a movable knife shaft is arranged on one side of the movable knife.

[0009] Preferably, the header assembly further comprises a first stem pulling roller arranged inside the shield, and a second stem pulling roller is arranged inside the shield.

[0010] Preferably, the grass-chopping assembly shell member includes a grass-chopping assembly shell body arranged on the rear surface of the straw-chopping chain bracket, and a mounting frame is arranged on the outer side of the grass-chopping assembly shell body.

[0011] The present invention further provides a corn harvester, comprising a second elevator, a first elevator disposed on one side of a shield, and:

[0012] A peeling machine is arranged at the bottom of the second elevator, a grain box is arranged at one side of the peeling machine, and a straw box is arranged on the rear surface of the grain box.

[0013] Preferably, an engine is provided at the bottom of the grain tank, and a bridge is provided on the rear surface of the header assembly.

[0014] Preferably, a ladder is provided on one side of the shield, and a cockpit is provided on the top of the ladder.

[0015] Preferably, a fan is provided at the bottom of the cockpit, a frame is provided at the bottom of the cockpit, and moving wheels are provided at the bottom of the frame.

[0016] Preferably, a grass box bracket is provided on one side of the grass box, and a grain box bracket is provided on one side of the grain box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention sets a cutting table assembly and a grass-chopping assembly, and the whole corn plant is cut off from the root by the lower cutter. The cut corn plant enters between two stem-pulling rollers under the clamping of the clamping chain. The first stem-pulling roller and the second stem-pulling roller rotate relative to each other, and transport the straw backward and enter the bridge. Since the gap between the stem-pulling rollers is relatively small, the corn cobs are removed from the whole corn plant by the stem-pulling rollers here, fall into the horizontal conveyor belt below, and then enter the first elevator. At the same time, the straw enters the shell of the grass-chopping assembly from the bridge, and then the straw can be cut by the rotating moving knife. The cut straw is transported backward and enters the fan. The equipment can realize the separation and harvesting of corn cobs and straw when harvesting corn. While harvesting the corn cobs, the straw is collected for use in the farm, and the efficiency is high and the maintenance is convenient.

[0019] 2. By setting the header assembly and the grass chopper assembly, the vertical header and the horizontal grass chopper are combined, and the corn stalks are harvested from the ground by the cutting knife. After the harvest, the whole corn plant passes through the vertical stem pulling roller to remove the corn cobs, so that the corn cobs and the straw are separated and enter different channels. The corn cobs enter the first elevator through the horizontal conveyor belt and then enter the peeling machine. The corn cobs peeled by the peeling machine enter the grain box, and the straw passes through the stem pulling roller and enters the horizontal grass chopper. The straw is cut by the grass chopper. After being chopped by the machine, the corn is sent to the grass box or the grass receiving cart through the second elevator, thus completing the corn harvesting process. Compared with the corn harvesting machinery with a vertical cutting table and a vertical hay chopper, the harvesting speed can be increased from 6-8 km / h to 10-13 km / h, and the efficiency is improved by more than 40%. Compared with the corn harvesting machinery with a horizontal cutting table and a horizontal hay chopper, it has a simple structure and is easy to maintain. When blockage occurs, you only need to flip the grass divider upwards to clear the weeds and other blockages, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
