The invention relates to asphalt tank automatic adjustment equipment for an asphalt concrete stirring system. The asphalt tank automatic adjustment equipment for asphalt concrete stirring system comprises a bottom plate, wherein an adjustment rotary device is mounted on the bottom plate; a fixed supporting frame is mounted at the front end of the bottom plate; a vertical plate is mounted at the rear end of the bottom plate; a fixed placement frame is mounted on the vertical plate through a pin shaft; the fixed placement frame and the adjustment rotary device are connected through a rotary manner; fixed protection devices are arranged at the front and rear ends of the fixed placement frame. According to the asphalt tank automatic adjustment equipment provided by the invention, the problemsof an existing asphalt tank that the volume of the asphalt tank is great and is relatively difficult to convey and fixed in an application process, and is difficult to clean and maintain are solved; the problems that slurry in the asphalt tank needs to be conveyed through a pipeline in the application process, the asphalt slurry is relatively thick so that the slurry at the bottom of the asphalt tank cannot be completely pumped when the slurry is pumped through the pipeline and the slurry is wasted, and the capacity of the asphalt tank is influenced through the slurry stacked at the bottom ofthe asphalt tank so that the service life of the asphalt tank is reduced are solved.

The invention discloses a multi-level buffer structure for a fitness running machine plate. The multi-level buffer structure comprises a body of a running machine, a running belt and a running plate are arranged on the body, a base is arranged at the bottom end of the body, rotating shafts and sliding rods are arranged at two ends of the base, the sliding rods are positioned on the outer sides of the rotating shafts, rotating rods arranged at two ends of each rotating shaft, rotating rod buffer devices are arranged on the rotating rods, rollers are arranged at the lower ends of the rotating rods, two sleeves are arranged on each sliding rod, a horizontal buffer spring is connected between two sleeves, two connecting seats are arranged on the body, the connecting rods are hinged to the lower ends of the two connecting seats and hinged to the sleeves, telescopic rods are arranged at two ends of the base, two telescopic holes are formed in the lower portion of each end of the body, and vertical buffer springs are arranged on the outer sides of the telescopic rods. According to the structure, multi-level buffer is achieved, multi-directional buffer damping is achieved, vibration sense is buffered layer by layer, the reverse impact force of the running machine on human bodies is decreased, and the pressure of knee joints and lumbar vertebras is relieved.

The invention discloses a pre-installation process of a small single-door refrigerator tank, which includes the following steps: S1, self-inspection: inspecting the appearance quality of the inner connecting wire and the return air coil in the single-door refrigerator to ensure that the inner connecting wire and the return air coil are The gas coil is flat, free of shape, damage and incomplete; S2, covered wire: take the qualified internal connecting wire in S1, and use the side with a length of 320-380 mm at a distance of 160-200 mm from the terminal of the internal connecting wire The adhesive foam tape wraps the connecting wires and fixes them, which is convenient for the internal connecting wires to seal the perforation of the refrigerated temperature control box, and the tape is pasted in the correct, firm, and in place, tightly sealed to prevent leakage, and the connecting wires are wrapped correctly; S3, pre-installed : Insert the qualified internal connection wire in S1 into the perforation of the temperature control box to the middle of the foam with glue, and seal and fix the perforation with two 100mm long pieces of foam with glue on one side. The refrigerator liner pre-installation process of the present invention can pre-install the refrigerator well, and the process is simple, the structure is compact, and it is very practical.

The invention discloses a large-span multifunctional plastic greenhouse which comprises vertical columns. A truss is fixedly mounted at the top end of the vertical columns, steel wires are horizontally arranged on the upper surface of the truss in a drawing manner, a greenhouse film is fixedly laid on the upper portion of the steel wires, heat preservation quilts are symmetrically arranged in themiddle of the top of the truss, rectangular ventilation openings are fixedly mounted on two sides of the top of the truss, a speed reducing motor is fixedly mounted on the inner wall of one side of each rectangular ventilation opening, the bottom ends of the rectangular ventilation openings penetrate the truss, an insect-proof net is fixedly mounted between the inner walls of the bottom ends of the rectangular ventilation openings, sunshine plate sealing covers are arranged at the tops of the rectangular ventilation openings, output shafts of the speed reducing motors are fixedly connected with threaded rotating shafts, first sliders symmetrically sleeve the surface of each threaded rotating shaft in a threaded manner, and a riveting frame is fixedly mounted on one side, close to the corresponding rectangular ventilation opening, of each sunshine plate sealing cover. The greenhouse is reasonable in structure, the ventilation automation degree of the greenhouse is improved, internal environment adjustment and control of the greenhouse is enhanced, the available time of the greenhouse is prolonged, and the utilization effect of the greenhouse is improved.
