Problems solved by technology

[0002] The header of the corn combine harvester is a key component that affects harvesting. No equipment has been able to complete the inspection of the fatigue performance of the header of the corn combine harvester.
However, the current Chinese national standard does not include fatigue performance in the performance index, resulting in uneven quality of existing corn headers
The header of the corn combine harvester is a nylon rod that simulates corn stalks. During the fatigue test, it rubs against the header roller and chain products to cause excessive wear and tear.
At present, there is no way to test the header equipment in the laboratory. In the past, the test was carried out together with the harvester during the harvest test. Due to time and space constraints, it is impossible to measure the normal working time of the header.

specific Embodiment approach

[0017] combine figure 1 , figure 2 and image 3 , the corn header fatigue test bench includes computer control system 1, the header fatigue test bench frame, and the nylon rod system for simulating corn stalks. The whole machine of the computer control system 1 adopts computer data acquisition and control, which has the advantages of accurate data acquisition and reliable control, and immediately controls the shutdown of the header when it is found to be faulty.

[0018] The header fatigue test bench frame includes a fixed bracket 3, on which a harvesting platform 2 is fixed, on which a motor 5 is installed, and the motor 5 is connected to the harvesting platform 2 through a transmission belt 6, and a threaded top is installed on the fixed bracket 3 Thread A11 and threaded top wire B12. A fixed guide tube A7 is installed on the threaded top screw A11. A spring A13 and a nylon rod A9 are arranged inside the fixed guide tube A7. A counting sensor 4 is installed inside the fix...

Abstract

The invention, which relates to the field of agricultural test mechanical equipment, discloses a fatigue test bench of a maize header. According to the fatigue test bench, a nylon stick is used for simulating harvesting of maize straws by a header of a maize harvester, thereby realizing balancing of the fatigue performance of the maize harvester header. The maize header fatigue test can be testedin any environment at any time; and the test cost is lowered, the labor is saved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of agricultural test machinery and equipment, in particular, the invention relates to a fatigue test bed for corn harvesters. Background technique [0002] The header of a corn combine harvester is a key component that affects harvesting. No equipment has been able to complete the inspection of the header fatigue performance of a corn combine harvester. However, the current Chinese national standard does not include fatigue performance in the performance index, resulting in uneven quality of existing corn headers. The header of the corn combine harvester is a nylon rod that simulates corn stalks. During the fatigue test, it rubs against the header roller and chain products to cause excessive wear. At present, there is no way to test the header equipment in the laboratory. In the past, the test was carried out together with the harvester during the harvest test. Due to time and space constraints, it is impossible to m...
