The utility model provides a slope runoff buffering water and soil conservation device, and aims to solve the problem of slope water and soil loss. The device is mainly composed of a slope buffering water and soil retaining plate and a flexible intercepting belt plate component. Flexible band plate radian adjusting pneumatic cylinders are arranged on the linkage plates on the two sides of the flexible interception band plate top plate, and the radian of the flexible band plate radian adjusting pneumatic cylinders can be adjusted through flexible band plate radian adjusting pneumatic rods and radian adjusting pneumatic rod tripods. The outer plate of the slope surface buffering water and soil conservation plate is provided with a buffering intercepting grating frame, the outer edge of the flexible intercepting belt plate is connected with a slope bottom arc-shaped grating frame, and buffering adjusting gratings with buffering strips are arranged on both the buffering intercepting grating frame and the slope bottom arc-shaped grating frame. In addition, a grid frame adjusting pneumatic cylinder and an arc-shaped grid frame adjusting pneumatic cylinder are arranged on the buffering and intercepting grid frame and the flexible intercepting belt plate correspondingly, and the position of the buffering and adjusting grid can be adjusted. The device can flexibly adapt to different slope runoff conditions, effectively buffer and intercept runoff and reduce water and soil loss, and has a good water and soil conservation effect and wide applicability.

The utility model discloses an air damping spring type large vehicle traction device, and belongs to the technical field of vehicle traction. An air damping spring type large vehicle traction device comprises a front traction beam and a rear traction beam hinged to the front traction beam, and the rear traction beam comprises a rear beam body and a cylinder fixedly connected to the rear beam body; one end of the traction rod is hinged to the front traction beam, a piston is fixedly connected to the traction rod and divides an inner cavity of the cylinder body into two damping cavities, damping parts are arranged in the two damping cavities, a through flow guide channel is formed in the piston, and the flow guide channel communicates with the two damping cavities; first-stage buffering is formed through the elastic force of the elastic damping piece, in the buffering process, along with the movement of the piston, gas in the two cavities is exchanged through the flow guide channel, and therefore the second-stage buffering and two-stage buffering mode is formed, and the buffering effect can be improved while the special strength of the traction rod is not increased. And a high buffering effect is still achieved for high impact force of braking of large vehicles.

This invention relates to the field of yarn tension control technology for winding machines, providing a pre-tensioning device and control method for winding machines, aiming to solve the quality problems caused by tension fluctuations in high-twist yarns during the winding process. The pre-tensioning device includes a fixed frame, a movable frame, a torque spring, an adjusting nut, and a plastic bearing. Rotating the adjusting nut changes the preload of the torque spring on the movable frame, thereby adjusting the output tension. The device utilizes the resilience of the torque spring to buffer and compensate for yarn tension fluctuations, reducing yarn vibration and lowering the probability of yarn kinking, webbing, and bobbin defects. The control method includes steps such as yarn preparation, yarn insertion, tension application, winding, yarn detection, and cutting, ensuring stable yarn tension and improving bobbin quality. This invention has a simple structure, low cost, is easy to install and maintain, and is suitable for various yarn types and process requirements.

The utility model provides an integrally-formed environment-friendly cushion package which comprises a package body, the package body is formed by cutting and folding a corrugated board to form a clamping seat and a first storage box body, the clamping seat is formed on one side of the storage box body, a second storage box body is formed at the bottom of the clamping seat, and the first storage box body and the second storage box body are arranged on the packaging body. An L-shaped storage cavity is formed in the upper surface of the second storage box body; a first buffer part is formed on one vertical side in the first storage box body, and a second buffer part is formed on one side of the inner side face of the top of the first storage box body; and on the basis that the good space utilization rate and the buffering effect are ensured, the forming efficiency is improved.
