Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a miniature corn combine harvester for hilly and mountainous areas. Background Art

[0002] The southwestern corn region is one of the three major corn producing areas in my country. However, due to the special terrain of the hilly and mountainous areas, machine field operations are ineffective or even impossible. Many small plots, steep slopes, and terraces can only be harvested manually, which is labor-intensive and has high labor costs.

[0003] The existing corn harvester integrates the functions of picking ears, peeling, threshing, cleaning, and returning straw to the field, and is widely used in large-scale planting on flat land. However, the machine is bulky and has poor operating performance, making it difficult to apply to corn harvesting in hilly and mountainous areas with more complex terrain. Therefore, a hilly and mountainous micro corn combine harvester is designed to effectively improve the level of mechanization in the southwest region. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a miniature corn combine harvester in hilly and mountainous areas. By driving the setting of the chassis, the two inner gear rods at the front end are made to deviate from each other, so that the two track feet are differentially driven to move forward. Since the spacing adjustment component 1 releases the restriction on the front end of the track foot, the front ends of the two track feet are opened to each other until the other end of the slide groove on the push rod contacts the inner gear rod again, and the motor 1 is started to make the outer gear rod move outward and contact with one end of the corresponding slide groove, and the two track feet move forward at the same speed, and the two inner gear rods in the spacing adjustment component 2 are controlled to move outward. As the track feet move forward, the rear ends of the two track feet deviate from each other until the two track feet are parallel again, and the two outer gear rods in the spacing adjustment component 2 are controlled to move outward, thereby re-limiting the corresponding push rod, thereby increasing the spacing between the two track feet, improving the passing performance in areas with large slopes, and adjusting the spacing between the two track feet as needed, and adjusting the overall center of gravity height accordingly, thereby improving the passing ability of the device in complex terrain, and facilitating use in mountainous and hilly areas.

[0034] When the distance between the two track feet 210 needs to be reduced, the front ends of the two track feet 210 are separated from each other, the transmission motor 234 is started, the two extension rods 236 are moved to the front side of the spacing adjustment component 1 260, the two outer gear rods 263 in the spacing adjustment component 270 are brought close to each other, the two track feet 210 are controlled to reverse, the device moves backward, so that the rear ends of the two track feet 210 are brought close to each other, and the inner gear rods 264 at the two rear ends are brought close to the middle, so as to fix the rear push rod 261, the two extension rods 236 are moved to the rear side of the two rear push rods 261, the height of the harvester body 100 is increased, and the two extension rods 236 are controlled to rotate. The outer gear rod 263 at the front end moves toward the middle, and as the device retreats, the front ends of the two track feet 210 move toward the middle under the dual effects of friction and the gravity of the harvester body 100 until the two track feet 210 are parallel again. The outer gear rod 263 at the front end contacts the corresponding push rod 261 again, and the two inner gear rods 264 at the front end are moved inward, thereby re-limiting the push rod 261 at the front end, reducing the distance between the two track feet 210, thereby improving the passability in narrow areas, and adjusting the distance between the two track feet 210 as needed, and adjusting the overall center of gravity height accordingly, thereby improving the passability of the device in complex terrain and facilitating use in mountainous and hilly areas.
