Description

Technical Field

[0001] The utility model belongs to the field of potato harvesting machinery and equipment, and particularly relates to a bar potato leakage prevention and damage reduction device suitable for a double-ridge potato harvester. Background Art

[0002] Potato is one of the largest grain crops in my country. It is also an important dual-purpose crop for grain and vegetables, and an important industrial raw material. The planting area of ​​potatoes in my country is extremely large, and now ranks first in the world. Potatoes are highly adaptable, can grow in various climatic conditions, and have high yields and are resistant to storage. These characteristics make them occupy an important position in agricultural production. At the same time, potatoes have high economic value, and their derivative products such as potato starch and French fries have a wide market demand, which further promotes their widespread planting in my country.

[0003] In the potato production process, harvesting is a very important link, but also a difficult part. The labor force accounts for more than one-third of the entire production process, and the operating cost accounts for more than 50% of the total production cost. At present, domestic potato harvesting machinery is still dominated by laying potato harvesters. However, due to the high price of large-scale combined harvesters, it is not price-friendly for ordinary farmers, and it is easy to cause mechanical damage to potatoes, so it is generally only used for starch potatoes.

[0004] At present, my country's laying potato harvesters generally install grass cutting discs in front of the harvesters to prevent potato seedlings and straw on the side ridges from causing congestion during harvesting. Therefore, multi-ridge potato harvesters need multiple sets of cutting discs when harvesting, which leads to a certain gap between the two sets of cutting discs. During the operation of the potato harvester, some potatoes will fall to the ground from the gaps in the cutting discs. The bars screen out the soil and leak it to the ground, burying the fallen potatoes. The soil is compacted by mechanical rollers, causing the potatoes to be pressed under the soil layer. It is difficult for subsequent workers to find the potatoes compacted by the soil when picking them up, resulting in a waste of potatoes. In order to increase the stability of the bar pitch, potato harvesters with a width exceeding a certain width generally need to install a belt. The plane formed between the belt and the bars cannot provide a large enough driving force for the potatoes, causing the potatoes to roll continuously on the middle belt and continuously collide with the middle belt clip, resulting in skin damage, which affects the skin breaking rate.

[0005] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it is revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model is created. A fence bar leakage prevention and damage reduction device suitable for a double-row potato harvester is provided to solve the above-mentioned problems. Utility Model Content

[0038] Working principle: When in use, the tractor output shaft cooperates with the transmission parts to realize the rotation of the chain row. As the tractor three-point suspension drives the potato harvester forward, the depth-limiting wheel flattens the uneven soil surface. As the main frame crossbeam moves forward synchronously, the rotation of the grass cutting disc cuts the straw and soil on both sides of the ridge to form a relatively regular ridge. The digging shovel goes deep into the soil to dig out the potato-soil mixture and transport it to the chain row. Due to the presence of the middle baffle assembly, the potato-soil mixture is difficult to flow through the gap between the two cutting discs. The rotation of the chain row can provide support for the potato-soil mixture, and continuously push the potato-soil mixture near the middle of the belt backward for transportation. At this time, the potatoes will not roll forward along the middle belt due to the lack of a force point, and fall under the harvester to cause potato leakage.
