The invention relates to the technical field of coal analysis and assay, and discloses a high-temperature sample rapid cooler which comprises a box body, at least one placing notch for placing a cylindrical cupel is formed in the surface of the box body, and a water inlet pipe is fixedly connected to one side of the box body. Through the non-contact cooling of the operation assembly and the placing notch, the rotation of the cupel ensures that the whole circumferential surface of the cupel can perform sufficient and uniform heat exchange with the low temperature conducted by the placing notch, so that the thermal stress generated by local shock cooling is effectively avoided, and further, due to the action of gravity, the heat transfer efficiency is improved. The high-density impurities such as unburnt gangue particles in the cupel can naturally settle and always gather at the bottom of the cupel, namely the position closest to the high-thermal-conductivity placing notch, so that the part which has the maximum thermal resistance and needs more cooling energy is just located in the optimal heat exchange area, and the cupel is suitable for underground laboratory places with extremely high anti-explosion requirements.

The application relates to the technical field of guide sticks, in particular to an intelligent guide stick based on an STM32 and a control system thereof, which comprises a guide stick rod, the guide stick rod is divided into three sections of upper, middle and lower, a power supply Bat, a loudspeaker SPK, an ultrasonic sensor HC-SR04, a fall judgment cancel button S2, a self-locking switch S1, an acceleration sensor ADXL345, a positioning module GSP and a short message communication module GSM are installed on the upper section of the guide stick rod; the application detects the existence of obstacles through an ultrasonic ranging circuit to give an obstacle avoidance reminder, detects the water level through a water level sensor to give a water accumulation reminder, combines the acceleration sensor to realize real-time monitoring of three-axis acceleration to achieve fall detection, and can also realize a GPS positioning function; if a user falls down and the button is not pressed within a certain time, an emergency help short message will be automatically sent to a preset number, and the current position information of the user is attached to the short message; meanwhile, the guide stick will play a help voice to ask for help from people around.

This utility model discloses a seed-mixing device for peanut cultivation, relating to the field of pesticide mixing technology. The device includes a casing with two pairs of fixed legs fixedly connected to its bottom. A feed inlet is located on one side of the upper surface of the casing, and a discharge outlet and a pesticide outlet are located on one side of the lower surface. A motor is fixedly connected to the center of the upper end of the casing. A pesticide tank is located near the motor at an eccentric position on the upper end of the casing. The pesticide tank is connected to the interior of the casing via a spray pipe. A rotating column is located on the upper part of the inner wall, with its upper end connected to the motor. A stirring blade is fixedly connected to the upper part of the rotating column, and a baffle is fixedly connected to the stirring blade. A brush rod is located at the bottom of the stirring blade. This seed-mixing device for peanut cultivation ensures that the peanuts fully contact the pesticide. The baffle on the stirring blade buffers the excessively fast rolling speed of the peanuts, preventing insufficient mixing due to excessive sliding, ensuring that each peanut is evenly coated with pesticide, and effectively improving the pest and disease protection effect of peanut seeds.

This disclosure relates to the technical field of concrete production equipment. One embodiment of this disclosure provides a stone feeding buffer device for concrete production, comprising: a shell, a feed inlet, and a separation outlet. The feed inlet is located at the top of the shell, the separation outlet is located on the inner surface of the shell, a drive motor is located on the side surface of the shell, a preliminary buffer assembly is located inside the shell, a discharge hood is located on one side of the bottom of the shell, and a secondary buffer assembly is located at the bottom of the shell. The preliminary buffer assembly includes a rotating roller rotatably connected inside the shell and connected to the output end of the drive motor. Several receiving racks are provided on the surface of the rotating roller. This technical solution solves the problem in the prior art where existing mixing plants add a buffer plate at the feed cylinder to reduce buffering force, but this arrangement easily leaves mixture residue on the buffer plate, affecting its use.
