Problems solved by technology

In actual operation, the walking speed of paddy field boat machinery is generally slow, which leads to very serious resistance problems when walking in paddy fields
Biomimetic surface drag reduction technology is a research hotspot in recent years, and its application is mainly concentrated in media such as air, water, and general soil. Since paddy fields are mud or mud-water mixtures, their physical properties are complex, and there is currently no relevant application of bionic surface drag reduction in paddy fields. Research

Embodiment 1

[0037] The paddy field boat mechanical bionic surface drag reduction structure is a bionic amphibian reptile abdominal epidermis pattern, and there are interconnected groove networks distributed on the outer surface of the hull in contact with the paddy field mud surface. In the groove network, the notch width of groove 1 is 1-40mm, and the depth is 5-50mm; the cross-sectional shape of groove 1 can be rectangular (such as Figure 9 shown), trapezoidal (as Figure 10 shown), inverted trapezoidal (as Figure 11 shown), triangles (such as Figure 12 shown), arcs (such as Figure 13 shown), unilateral trapezoid (such as Figure 14 shown), unilateral triangles (such as Figure 15 shown), but the shape is not limited to this, such as other polygons and multi-end arcs, etc. In the groove network, the shape of a single grid is preferably a staggered rectangle (such as Figure 4 shown), parallelogram (such as Figure 5 shown) or imitation moire hexagon (such as Figure 6 shown)...

Abstract

The invention discloses a paddy field boat form machine bionic surface anti-drag structure and applications thereof. The structure simulates the belly epidermis lines of amphibian reptile, and groove networks communicated with one another are distributed on the outer surface of a boat contacted with the mud of paddy field; when the boat travels at low speed, a water membrane can be formed on the outer surface of the boat, so as to reduce the resistance of the paddy field boat form machine while travelling in the paddy field at low speed. Due to the adhesive force and the friction force between the boat surface and the mud, water on the outer side of the boat constantly supplement energy consumed in water membrane formation along the grooves communicated with one another, so that the water membrane is formed continuously, thus reducing the resistance of the boat during travelling. The paddy field boat form machine bionic surface anti-drag structure is low in cost and is applicable to boat form machines in environments including intertidal zones and marshes.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a bionic surface drag-reducing structure of paddy field boat-type machinery and its application. Background technique [0002] At present, paddy field boat machinery is widely used in paddy field operation machinery for carrying and walking, mainly including single hull and multihull: single hull such as figure 1 A kind of rice transplanter shown, the rice transplanting mechanism is carried by a hull; figure 2 In the shown stepping rice transplanter, the rice transplanting mechanism is weight-shared by two hulls. The hull of paddy field boat machinery mainly plays the role of carrying weight, and the outer surface of the hull is generally smooth to reduce resistance during walking. However, when the paddy field boat machinery walks in the paddy field at a low speed, the resistance will be much greater than that at a high speed. This is due to the weight of the hull, and t...
