Description

Technical Field

[0001] The present invention belongs to the technical field of ridging devices, and in particular relates to a counter-rotating propulsion rotary tillage ridging machine. Background Art

[0002] Ridge cultivation is a commonly used planting method for crops such as strawberries, potatoes, and cassava. Its core advantage is that it improves crop growth efficiency and yield by improving soil environment and management conditions. It also has the advantages of drainage and waterlogging prevention, avoiding root diseases, promoting early maturity, optimizing light and ventilation, reducing diseases, and adapting to crop growth characteristics. It ensures rapid germination and optimal growth conditions for strawberries, potatoes, cassava and all other crops that require this effective cultivation method.

[0003] In order to achieve the standard ridge shape, reduce power consumption, and facilitate the operation of some crops in greenhouses, the ridging machine is required to be small and compact to achieve the operation goals of high efficiency, energy saving and emission reduction. At present, the main operation form of the common ridging machine on the market is the rotary tillage and ridging sequence combination operation machine, that is, a ridging device is organically combined behind the ordinary rotary tiller, which has the characteristics of wide operation width, high energy consumption, and low ridging height. It needs to be equipped with a high-horsepower tractor as power input, which is not conducive to operation in the cramped space of facility agriculture operation scenes such as greenhouses; the rotary tiller blade is generally a horizontal axis, the layout direction is perpendicular to the forward direction of the tractor, and the blade shaft is full of rotary tillers. For ridging operations, the rotary tillage area is too large, resulting in power waste and increased energy costs; in addition, the rotary tiller blade of an ordinary forward rotary tiller cuts the soil from top to bottom, and the soil cutting force becomes larger and larger during this process, which is also the main reason for the high energy consumption of the rotary tiller.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies.

[0005] The present invention provides a counter-rotating propulsion rotary tiller and ridger, which aims to reduce the amount of soil tillage, reduce the cutting force required for soil crushing, and reduce the volume of the machine, thereby achieving drag reduction and consumption reduction, efficient and flexible operation, improving the diversity and adaptability of machine application scenarios, and helping farmers reduce costs and increase efficiency.

Figure 9-10 As shown in the figure, while the rotary tiller rotates, the positive cutting edge in the soil cutting area first cuts into the soil, and the cut soil is separated from the soil layer by the shear force. Then the sliding cutting edge continues to cut deeply, so that the cut soil is completely separated from the soil layer and piled up in the soil throwing area of ​​the rotary tiller. At this time, the cut soil is simultaneously subjected to the tangential force Ft of the soil throwing baffle and the radial force Fn of the soil cutting area. As the rotary tiller rotates at a high speed, it is finally thrown to the middle area of ​​the machine along the direction of the resultant force F, forming a soil pile, as shown in the figure. Fig.11 As shown, when the rotary tiller moves forward, the soil pile is squeezed by the two sides and the upper side of the soil pressing plate on the rotary tiller body cover 17, and the soil pile is squeezed from loose to compact, and finally forms the expected ridge shape.
