The invention discloses a unidirectional clutch type stepless speed change device for off-road motor vehicles, comprising a driving wheel component (1), a driven wheel component (4), a belt (3); the driving wheel component (1) comprises a pulley (6), an axle (13), a sliding sleeve (7), a spring seat (8), a pressure roller (9), a driving wheel spring (11), a supporting wheel (10); wherein, the sliding sleeve (7), the spring seat (8) and the pressure roller (9) are sheathed on the axle (13) and are positioned by the supporting wheel (10), the driving wheel spring (11) is arranged between the spring seat (8) and the pressure roller (9); the inner surface of the sliding sleeve (7) is provided with spiral grooves (22), spiral guide surfaces (21) facilitate the transition between two spiral grooves, the axle (13) is provided with pin springs (14) and pins (15), the pins (15) are contacted with the spiral grooves (22) of the sliding sleeve (7). With the structure adopted, the unidirectional clutch type stepless speed change device has the characteristics of simple and reasonable structure, reliable performance and small volume, high integrity and convenient operation and maintenance.

The invention discloses a universal soft cable. The universal soft cable comprises a first rotation shaft, multiple joints, a second rotation shaft, a first connector and a second connector; the firstrotation shaft, the multiple joints and the second rotation shaft are sequentially connected through pin shafts in series in a hinged mode, and the axes of the two pin shafts on the same joint are not located in a same plane; the first connector is arranged outside the first rotation shaft in a sleeving mode, and the first rotation shaft can rotate; the second connector is arranged outside the second rotation shaft in a sleeving mode, and the second rotation shaft can rotate; and when the first rotation shaft rotates, the second rotation shaft can be driven to rotate through linkage of the multiple joints. The universal soft cable further comprises a soft casing pipe, the two ends of the soft casing pipe are fixed to the first connector and the second connector separately, the multiple joints penetrate into the soft casing pipe, therefore, the soft casing pipe can provide safety protection for the multiple joints, and meanwhile the multiple joints can orderly and evenly distribute therotation angles. The universal soft cable further comprises hoops which can enable the soft casing pipe to be compressed outside the first connector or the second connector in a sleeving mode. A 90-degree included angle is formed between the axes of the two pin shaft on the same joint. The universal soft cable has the beneficial effects that the structure is simple, the cost is low, universal torque transmission is achieved, and the torque transmission efficiency is high.

The invention discloses a soil remediation device capable of simultaneously stirring and conveying soil. The soil remediation device comprises a material inlet part, and the material inlet part comprises a first conveyor belt and a material inlet hopper; an outlet in the lower part of the material inlet hopper is arranged above the first conveyor belt, a screener covers an inlet in the upper part of the material inlet hopper, the upper surface of the screener has a predetermined slope, and the lower side of the upper surface of the screener extends to the outer side of the soil remediation device to intercept impurities exceeding a designed remediation maximum size or agglomerated soil to the outside of the soil remediation device; and the front and rear parts of the first conveyor belt are respectively provided with one power roller. The device provided by the invention has the following beneficial effects: one side, close to the middle of a stirring cabin, of each rotating shaft rotates from the bottom to the top, so that the soil accumulated in the middle of the conveyor belt is evacuated to two sides, a stirring tooth plate with an inclined angle is also used, so that the soil is pushed forwards, and the soil is conveyed by a second conveyor belt while the soil is stirred.
