This invention relates to the field of agricultural drone technology and discloses a vibration-damping medicine storage box for agricultural drones, comprising a fixed plate, a buffer pad, a shock-absorbing plate, a shock-absorbing spring, a connecting frame, and a medicine box. The fixed plate is bolted to the bottom of the drone, and a buffer pad made of elastic material is installed between the fixed plate and the drone. The shock-absorbing plate is slidably connected to the fixed plate, and the shock-absorbing plate is connected to the fixed plate by a shock-absorbing spring, with both ends of the shock-absorbing spring fixed to the shock-absorbing plate and the fixed plate respectively. The buffer pad absorbs high-frequency vibrations, while the shock-absorbing spring provides low-frequency buffering. The two work together to reduce the impact of vibrations of different frequency bands on the medicine box. Compared with a single shock-absorbing structure, this design can more effectively suppress complex vibrations, reduce the amplitude of liquid sloshing, improve the uniformity of application, and at the same time reduce the increase in energy consumption and structural fatigue of the drone caused by vibration.

The embodiment of the invention discloses a method for achieving high-density compression and a mixture target, the method is applied to the mixture target, the mixture target comprises a container and a mixture contained in the container, and the mixture comprises a low-impedance base material and high-impedance particles; the method comprises the following steps: carrying out single impact loading on a mixture target by using impact waves; wherein in the single impact loading process, the impedance mismatch between the high-impedance particles and the low-impedance matrix material is utilized, so that the low-impedance matrix material is compressed to be higher than the density of the main Rayleigong state in the single impact process, and the density of the low-impedance matrix material is higher than the density of the main Rayleigong state; the effect that the density of the low-impedance material is directly higher than that of the main Rayleigh gong state through a single impact process under the conventional impact loading condition can be achieved.

This invention belongs to the field of shock absorber technology and relates to a large-size wellbore axial shock absorber, including an upper connector, a housing, and a lower connector. The housing is fitted onto the outer wall of the upper connector, and a receiving cavity is formed between the inner wall of the housing and the outer wall of the upper connector. A disc spring shock absorber assembly is installed in the receiving cavity. A hydraulic shock absorber assembly is connected to the bottom of the housing, and the lower connector is connected to the bottom of the hydraulic shock absorber assembly. The hydraulic shock absorber assembly includes a hydraulic shell, a piston, and a hydraulic sealing seat. The hydraulic shell is fitted onto the bottom of the housing, and the hydraulic sealing seat communicates with the bottom of the hydraulic shell and forms a hydraulic cavity inside. The piston slides through the hydraulic sealing seat and is slidably disposed in the hydraulic cavity. The piston has a hydraulic through hole, and an electromagnetic proportional valve is connected to the hydraulic through hole. This invention improves the problem of existing technology's single shock absorber element and fixed parameters, which are difficult to adapt to the vibration characteristics of large-size wellbores, by combining disc spring and hydraulic shock absorption, adaptive stiffness of shape memory alloy adjustment plate, and active adjustment by electromagnetic proportional valve.
