Turning specifically to the helical advancing roller structure of the present application.

In the preferred scheme in this application, the ratio of the height r2 of spiral propulsion plate 21 to the radius r1 of drum 2 is 0.3~0.35, can provide great thrust output. The ratio of the pitch p of each spiral propelling plate 21 to the height r2 of each spiral propelling plate 21 is 6-6.5, the ratio is an optimized ratio obtained after continuous tests, the spiral propelling plate is not easy to slip, and the output power is large. In addition, the helix angle alpha of the helical propulsion plate 21 is 13-17 degrees, preferably 15 degrees, and the helical propulsion plate is suitable for being used in mudflats and marshes.

Specifically, the effective length of the roller 2 is 1.1 m-1.3 m, and preferably 1.2 m. The roller 2 is provided with two spiral pushing plates 21, and each spiral pushing plate 21 has 2-3 spiral lines; the height of the spiral propulsion plate 21 is 7 cm-10 cm, and 8cm is preferable. The propelling device in the structure provides large thrust, has high advancing speed and cannot slip.

In the single-side double-drum screw propulsion device, two drums 2 are arranged on one side of the single-side double-drum screw propulsion device, and the four drums 2 on two sides are driven to rotate by a driving assembly 16 and are independently controlled. When rotating, the spiral propulsion board 21 takes place the extrusion with the muddy ground, produces thrust, makes the integrated device advance or retreat, convenient operation, and four cylinders 2 can also realize operations such as translation, turn through the regulation and control and the cooperation of rotation direction, slew velocity simultaneously, make the flexibility that the integrated device removed better. The body typically has a submerged cavity for pressing against mud to create buoyancy, while other functional components may be disposed in the body.

Specifically, the propulsion device with the single spiral propulsion plate roller is suitable for water bodies, relatively thin mud flats or swamps, the fluid resistance is relatively low in the use environment, the single spiral propeller can complete propulsion operation, and the advancing speed can be increased by accelerating the rotating speed, widening the screw pitch and the like.

In a preferred embodiment, 2-3 spiral pushing plates 21 are arranged on the outer wall of each roller 2, and the spiral pushing plates 21 are uniformly distributed and have the same pitch. The structure of many spiral propulsion boards can increase the density of spiral propulsion board under the condition of not changing the helix angle, under the same rotational speed, compares in single helical structure, can provide bigger thrust, the phenomenon of skidding can not appear simultaneously, uses in being applicable to mud flat, marsh.

In one embodiment of the invention, the propulsion device is composed of four helical drums, and each hollow helical drum has two helical propulsion plates 21 on the outer circle. The spiral directions of the front and back symmetrical positions and the left and right symmetrical positions are opposite, each roller is driven by a single hydraulic motor or an electric motor, and the rotation direction and the rotation speed of the rollers can be independently controlled, so that the running speed and the running direction of the vehicle can be changed.

Specifically, the method comprises the following steps: when the vehicle runs in a straight line, the rotating directions of the front and the rear rollers at the same side are required to be opposite, and the rotating directions of the left and the right rollers are also required to be opposite, so that two running modes of advancing and retreating can be realized. When the vehicle body transversely moves, the rotating directions of the front roller and the rear roller on the same side are required to be the same, and the rotating directions of the left roller and the right roller are also required to be the same, so that the vehicle body transversely moves to the left side and the right side. When the vehicle runs on a curve, the rotating speed of the rollers on the two sides can be controlled to realize steering leftwards and rightwards until the vehicle turns in place.

When the diameter and the rotation speed of the drum are constant, the pitch is increased to increase the running speed of the entire vehicle, but the adhesion condition to the ground is deteriorated (the number of spiral blades in contact with the ground is decreased), and the slip is likely to occur. This problem is reasonably solved by using a plurality of screw propulsion plates. The height of the blade of the spiral propelling plate is also a main factor for determining the adhesion performance of the roller, and the adhesion performance can be improved by increasing the height of the blade. However, if the amount exceeds a certain value, the resistance of the blade to cut into the soil is increased, and the driving resistance is increased, which is disadvantageous to the rotation of the roller.
