The utility model discloses a Hall current sensor, which comprises a sensor main body, a connecting shaft is vertically fixed at the bottom of the sensor main body, a sensor supporting seat is arranged at the bottom of the connecting shaft, a spring is sleeved on the connecting shaft, and the spring is arranged between the sensor main body and the sensor supporting seat. A bevel gear is fixed to the lower portion of the connecting shaft, and a meshing groove matched with the bevel gear is formed in the middle of the bottom of the sensor supporting base. According to the utility model, when the sensor main body needs to be rotated, the sensor main body needs to be pressed down firstly, so that the bevel gear on the connecting shaft is separated from the bottom of the meshing groove, and when the rotation is completed and the sensor main body is loosened, the spring pushes the connecting shaft to slide upwards, so that the bevel gear enters the meshing groove again, and then the locking is completed. According to the utility model, the angle adjustment of the sensor main body is simpler and more effective.

The present invention discloses an indoor test device and test method for measuring dynamic spray deposition of a plant protection UAV, which solves the problem of low accuracy of droplet deposition test data in the prior art. The indoor test device for measuring dynamic spray deposition of a plant protection UAV of the present invention has a lifting frame on the test bench, a sliding mechanism on the lifting frame, an adjustable nozzle assembly on the sliding mechanism, a flow sensor on the adjustable nozzle assembly, and the adjustable nozzle assembly is connected to a liquid storage tank arranged on the test bench through a hose; a sliding table for holding crops is arranged in the test bench, and a laser radar is arranged on the sliding table. The indoor test method for measuring dynamic spray deposition of the present invention can not only obtain the spray width and fog field distribution data of the plant protection UAV at different speeds, but also obtain the data on the influence of the environment (wind force, temperature) on the spray deposition amount. The test is simpler and more intuitive, and provides accurate data support for the spraying of the plant protection UAV.

The utility model passes through using double ball cage constant velocity universal joint, can make tractor group more safe when turning angle is larger;By increasing shift mechanism, tractor group can have greater driving force.

The utility model discloses a liquid spraying mechanism of a liquid inoculation machine, which relates to the technical field of liquid inoculation machines and comprises a bottom plate, the top end of the bottom plate is fixedly connected with a water tank, the top end of the water tank is fixedly provided with a liquid spraying device, and the liquid spraying device comprises two supports. The upper portions of one ends of the opposite faces of the two supports are jointly and rotationally connected with a shell, one end of the shell is provided with a first motor, the top end of the water tank is fixedly connected with a pump body, the output end of the pump body is connected with a water inlet pipe in a penetrating mode, and the input end of the pump body is connected with a water outlet pipe in a penetrating mode. The top end of the water outlet pipe penetrates through the outer surface of the shell and is fixedly connected with a connecting pipe, and the outer surface of the connecting pipe is fixedly connected with a plurality of spray heads distributed in an annular array in a penetrating mode. And the liquid spraying angle of the liquid spraying mechanism can be effectively adjusted.

This invention relates to the field of welding torch wire feeding mechanism technology, specifically a welding torch wire feeding mechanism with freely adjustable angle. It includes a wire stabilization mechanism, a lifting assembly mounted outside the wire stabilization mechanism and mounted on the welding torch nozzle, a wire delivery mechanism mounted on the wire stabilization mechanism, a lateral angle adjustment mechanism mounted on the wire stabilization mechanism, and four sets of alignment components disposed on the wire stabilization mechanism and the wire delivery mechanism. The wire stabilization mechanism includes a sleeve. By fixing the lifting assembly to the welding torch nozzle and installing the wire stabilization mechanism parallel to the nozzle within the lifting assembly, and using the lateral angle adjustment mechanism to control the lateral angle change of the wire delivery mechanism, the welding wire extending from the wire delivery mechanism can be effectively angled. This provides an unobstructed path for wire delivery at different angles according to the tilt state of the welding torch and the workpiece.
