The application relates to the technical field of four-wheel positioning, and discloses a four-wheel positioning adjustment auxiliary assembly, a structure and a use method. The four-wheel positioning adjustment auxiliary assembly comprises a supporting cover plate, a through hole is arranged on the supporting cover plate, a push column slides along the through hole, a push block is fixed on the push column, a variable-diameter sleeve is sleeved on the push column, and a locking structure is used for locking the position of the push column in the through hole. The variable-diameter sleeve of the auxiliary assembly adjusts the position of the eccentric bolt, changes the posture of a multi-link suspension upper plate swing arm assembly, adjusts the wheel inclination, the position of the eccentric bolt is determined by the top holding and limiting of the variable-diameter sleeve, the eccentric bolt cannot swing towards the recovery position, and the adjustment precision is high.

The invention relates to the technical field of forestry robots and intelligent nondestructive testing, in particular to a tree body disease and pest detection robot based on knocking-echo analysis. The robot comprises a movable climbing mechanism, a variable-diameter mechanical claw driving mechanism and a knocking detection and intelligent marking mechanism. The movable climbing mechanism is matched with a tensioning wheel and a guide frame through a multi-connecting-rod suspension type main body frame, and self-adaptive climbing and stable attachment of the robot on the surfaces of different trunks can be achieved. The variable-diameter mechanical claw driving mechanism drives a transmission sliding block through a transmission motor and drives a clamping frame to achieve self-adaptive clamping of a tree. The knocking detection and intelligent marking mechanism drives a knocking mechanism to generate high-frequency mechanical knocking through a knocking motor, echo signals are collected through a sonic sensor, the positions of plant diseases and insect pests are positioned after the echo signals are analyzed and processed through a main controller, and accurate spraying marking is conducted through the intelligent marking mechanism capable of moving along a track. According to the invention, automatic and nondestructive detection and intelligent marking of plant diseases and insect pests in the tree body are realized, and the problems that the traditional manual detection efficiency is low, the chemical control pollution is serious and the existing robot lacks a tree interior detection function are effectively solved.

Various suspension systems for vehicles are described that preferably comprise a multi-link suspension where one or more of the links can move independently of the other links. The multiple independent links are connected to an upright, vertical load reaction that is decoupled from horizontal load reaction, thus delivering a more comfortable ride and reduced feedback to the driver or operator of the vehicle. By eliminating that external feedback using the inventive subject matter discussed herein, vehicles can be safer and easier to control in all circumstances.

This invention relates to the field of intelligent machine technology, specifically to a suspension-adaptive magnetic adsorption pipe-climbing robot, comprising a vehicle body, front and rear drive mechanisms, a control module, sensing devices, and permanent magnet adsorption wheels. The front vehicle body is connected to the upper vehicle body via a yaw-rotation joint and is equipped with a multi-link suspension adaptive mechanism, which can passively adapt to changes in pipe curvature to ensure full contact adsorption of the magnetic wheels. The drive mechanism uses a gear transmission set to drive four permanent magnet adsorption wheels respectively. The control module detects the attitude of the front vehicle body in real time and adjusts the speed of each wheel in a closed loop to achieve motion synchronization and path tracking. This invention effectively solves the problems of adsorption instability, motion stagnation, and trajectory deviation caused by "single wheel suspension" in traditional robots in variable curvature pipes by combining mechanical adaptation and active control. It significantly improves the robot's passability, motion stability, and reliability of inspection operations in complex pipe environments such as bends and sharp corners.
