The invention discloses a fibre cutting device for an asphalt-macadam synchronous sealing vehicle or equipment. The fibre cutting device comprises a fibre raw material installed on the sealing vehicle or equipment, wherein a steel tube channel for leading in the fibre raw material is arranged above the fibre raw material, a hose channel stretching downwards and leading the fibre raw material into a fibre cutting assembly arranged below the sealing vehicle or equipment is connected to one end of the steel tube channel, and at least one rotary cutting tool for cutting the fibre raw material to a certain length is arranged in the fibre cutting assembly; the fibre cutting assembly comprises a drive wheel driven by a hydraulic motor, wherein the drive wheel is adjacent and next to a rotary cutting tool driven through a manual friction force; a high-pressure air blowing-away nozzle capable of blowing away the cut fibres to a construction road surface is installed below the rotary cutting tool; the rotary cutting tool is connected with a cutting tool opening-closing cylinder for realizing the opening-closing of the cutting tool and the scattering width adjustment of the fibres.

The invention discloses an adjustable temperature control valve which comprises a valve body. The middle of one end of the valve body is connected with a cylindrical heating element, an expansion control sleeve is sleeved on the radial circumferential surface of the heating element, an inner hole of the expansion control sleeve is adaptive to the outer diameter of the heating element, more than three radial bolt through holes are uniformly distributed along the circumferential direction of the expansion control sleeve, and an adjusting bolt is arranged in each bolt through hole. The adjustable temperature control valve is simple in structure and convenient to manufacture and use, normal working life of the temperature control valve can be prolonged greatly as compared with that in the past, failure rate of shutdown caused by rising of oil temperature is decreased, maintenance frequency is reduced, and maintenance and replacement workload and corresponding labor and component cost are reduced.

The invention discloses a stirring device for a bidirectional stirring pile machine and a using method, the stirring device comprises a suspension mechanism, a stirring mechanism and a driving mechanism, the driving mechanism comprises an upper power head, a lower power head and a lifting assembly for driving the lower power head to be close to or away from the upper power head; the stirring mechanism comprises a drill rod assembly and a bidirectional stirring drill bit which are axially connected, the upper power head is connected with an upper output shaft used for being connected with the upper end of an inner drill rod unit of the drill rod assembly, and the lower power head is connected with a lower output shaft used for being connected with the upper end of an outer drill rod unit of the drill rod assembly. The lower end of the upper output shaft is slidably arranged in an inner hole of the lower output shaft in a penetrating mode. According to the stirring device for the bidirectional stirring pile machine and the installation method, accurate and stable installation of the inner drill rod and the outer drill rod of the drill rod assembly can be achieved, installation is convenient, and the labor intensity of workers is reduced.

The invention provides a passive variable-rigidity longitudinal thrust rod and an air suspension for installing the longitudinal thrust rod. The longitudinal thrust rod comprises a front lifting ring, a rear lifting ring, a front spring, a rear spring, a working cavity, a supporting rod, a front piston, a rear piston, a piston rod, rubber sleeves, a connecting rod and oil liquid. The air suspension comprises a four-connecting-rod guiding mechanism, a shock absorber, an air spring, a connecting plate and a balance beam. The four-connecting-rod guiding mechanism comprises the two longitudinal thrust rods and a V-shaped rod. Under the emergent acceleration and emergent deceleration working conditions, the rigidity value of the longitudinal thrust rod increases and is equivalent to that of a rigid rod, so that the air spring is protected against longitudinal force, and the stability of an automobile is improved. Under other driving working conditions, the overall rigidity of the longitudinal thrust rod is decreased, and large damping force can be generated when the oil liquid flows through a middle long and thin pipeline, so that the driving smoothness of the automobile is improved. Both the stability and smoothness of the automobile are taken into account under different working conditions. In addition, through the adjustable rigidity and the damping function of the longitudinal thrust rod, the characteristics of the four-connecting-rod guiding mechanisms are further improved.

The invention particularly relates to a bamboo broad-spectrum composite artificial fish nest. The problems that an existing artificial fish nest cannot meet soft media and hard media needed by fish spawning at the same time, the flood, storm and water flow resisting capacity is poor, and bait organisms cannot be provided are solved. The bamboo broad-spectrum composite artificial fish nest is composed of a fixed pile, a connecting pile, a hard medium artificial fish nest, a soft medium artificial fish nest, a connecting steel wire rope and a strapping tape. The hard medium artificial fish nest is formed by connecting a plurality of bamboo spawning base artificial fish nests on the connecting steel wire rope in series, and the soft medium artificial fish nest is formed by connecting a plurality of palm sheet bundle artificial fish nests on the connecting steel wire rope in series. The palm sheet bundle artificial fish nest is composed of palm sheet bundles and palm sheet bundle fixing rods. The bamboo broad-spectrum composite artificial fish nest is used for providing a spawning site for fishes laying viscous eggs.
