The invention discloses an intelligent control system for separating and screening barium ore, and belongs to the technical field of industrial process control. The system specifically comprises an ore data acquisition module, a multi-dimensional feature extraction and fusion module, a classifier engine module and a sorting control module, the ore data acquisition module acquires original ore data through a multi-dimensional sensor; the multi-dimensional feature extraction and fusion module performs feature extraction and fusion based on original data; the classifier engine module identifies, classifies and screens the barium ore to form a control instruction based on the fusion features by using a machine learning algorithm; the sorting control module executes a screening action based on the control instruction. According to the method, a solution of combining multi-sensor information fusion and a lightweight machine learning classifier is utilized, and technical guarantee is provided for precise separation of barium ore and self-adaptive control.

The utility model discloses a driving mechanism which is arranged in a second space formed by a shell and a lower sleeve body and comprises a rotary body, a pipe frame, a push rod, a spring and an actuating piece. The rotary body is rotationally arranged on the inner side of the shell, and the rotary body partially extends into the lower sleeve body and is connected with the lower sleeve body; the pipe frame is arranged on the inner side of the rotary body, rotates along with the rotary body all the time and can only move up and down in the axial direction of the rotary body. The push rod extends to the position above the shell from the pipe frame and is used for applying thrust to a target object; the spring is arranged below the pipe frame; the actuating piece is arranged above the rotary body and can reciprocate in the shell in the radial direction; the driving mechanism is convenient to operate, more stable pushing force can be provided by using a spring instead of a lifting handle, the atomization effect of the device is remarkably improved, the consistency of each spraying of the device is good by using a disposable medicine bottle to be matched with stable pushing force output, and daily precise medicine taking of a patient is facilitated.

This utility model discloses a masking tool for painting the side roof of a rail vehicle, comprising four masking plates that abut against each other to form a rectangular painting area. With this utility model, the user can slide and adjust the positions of the four masking plates according to the size of the area to be painted, making the rectangular painting area slightly larger than the painting area. This allows the operator to simply apply a small amount of tape around the painting area, then place the adjusted masking plate on the repair part. After fixing the masking plate to the repair part using a suction cup assembly, the cover is connected to both the masking plate and an air purification device. This allows the operator to extend their arm holding the spray gun from inside the sleeve into the cover to spray the area requiring painting. Due to the cooperation of the masking plates and the cover, excess paint mist is prevented from accidentally spraying onto other intact painted surfaces. Furthermore, after painting, the masking tool can be removed simply by removing a small amount of tape, thereby improving the efficiency of the painting process.

The utility model relates to a kind of surface treatment devices for fuel filter shell, including providing the base of lifting assembly plane, the box shell capable of defining surface treatment chamber is suspended and supported by support column on the base, and the parallel conveyer belt capable of driving column shell workpiece to pass in surface treatment chamber is laterally provided in the box shell, and spraying mechanism is arranged on the alignment side wall surface of the box shell at the both sides of the parallel conveyer belt;Rotary clamping seat capable of self-adaptively supporting and limiting column shell workpiece is also spaced on the parallel conveyer belt, wherein, the rotary clamping seat is engaged with the rack on the inner side wall of the box shell according to the synchronous rotation around axis of its can occur in the process of directional translation following the parallel conveyer belt.The utility model can realize uniform and sufficient high-quality spraying while carrying out continuous batch spraying processing.

The utility model relates to medical instrument technical field discloses portable anesthesia spray dosing device, including medicine bottle, the top of medicine bottle is provided with medicine spraying subassembly, the inside slide coupling of medicine spraying subassembly has slide rod, the outside fixed connection of slide rod has fixed disc, the outside of slide rod is equipped with spring, the inside of medicine spraying subassembly is provided with the sliding slot, the outside rotation of slide rod is connected with the locating ring, the front side fixed connection of slide rod has the pull plate, the outside fixed connection of slide rod has the cam, the rear side fixed connection of cam has the clamping post, the inside of medicine spraying subassembly is provided with the clamping slot, medicine spraying subassembly includes sealed shell, the bottom screw thread connection of sealed shell in the top of medicine bottle, in the utility model, when not operating, the pressing block always locks, effectively avoids medicine mispours, effectively prevents the medicine spraying due to accidental touch, ensures the security and accuracy of medicine use.
