Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a large-scale turnover plow with a rear-mounted turnover mechanism. Background Art

[0002] Large reversible plows are currently widely used in agricultural production, such as in Heilongjiang agricultural reclamation area, Xinjiang, Inner Mongolia, Gansu, etc. These areas have flat and open land and large farmland, and the high-efficiency operation advantages of large reversible plows can be fully utilized.

[0003] However, large reversible plows also have the following disadvantages: 1. Reduced steering flexibility: When the reversible plow is too long, it becomes very difficult to turn in the field. For example, when working on a small piece of farmland, a tractor pulling a reversible plow that is too long may not be able to successfully complete a small angle turn. As the length of the reversible plow increases, its turning radius will also increase accordingly. This will result in more open space being required to complete the turning operation when working in the boundary area of ​​the farmland, reducing the effective utilization rate of the land.

[0004] 2. Inconvenient transportation: Overlong flip plows are subject to many restrictions during road transportation. First, the part that exceeds the standard length of vehicle transportation may violate traffic regulations and require special transportation permits. Second, it will affect the stability of transportation. Due to its long length, it is easy to shake during transportation, especially when passing through bumpy roads or turning, which may cause safety accidents such as rollovers. Moreover, during the transfer between fields and roads, overlong flip plows have higher requirements for the passability of roads and field entrances, and may not be able to pass through some narrow passages or bridges smoothly.

[0005] 3. Increased power transmission loss: A too long reversible plow will increase the distance of power transmission. When the tractor pulls the reversible plow, the power is transmitted from the tractor to the plowshare to turn the soil. As the length of the reversible plow increases, the power loss during the transmission process will increase. For example, due to factors such as friction and torsional force between the transmission parts, the plowshare's ability to penetrate the soil and the efficiency of turning the soil will decrease.

[0006] 4. Uneven soil turning: When a reversible plow that is too long is in operation, the relative positions of the plow body and the tractor are quite different, which makes it difficult for the plow body in different positions to maintain consistent penetration angles and depths. The plow body part close to the tractor and the plow body part far from the tractor will experience different resistance when the soil texture is uneven or the terrain is undulating. This will make the soil turning effect uneven, with some places turning the soil too deep and some places turning the soil too shallow, affecting subsequent planting operations.
