The utility model relates to the technical field of valve bevel grinding machine spindles, in particular to an automatic balance spindle device for a valve bevel grinding machine, which comprises a main body, and the top of the main body is fixedly connected with an adjusting component and a positioning component; according to the utility model, the horizontal position of the main shaft of the valve bevel grinding machine is positioned under the action of the laser transmitter and the laser receiver, so that the main shaft can be balanced more quickly and accurately when being automatically balanced, and the positioning device is a non-contact positioning method, does not need to be in direct contact with a measured object, and is convenient to operate. According to the characteristic, damage or interference to a measured object is avoided, the electric control actuator is used for receiving an inclination signal and controlling the telescopic rod to stretch out and draw back, then inclination balance of the shaft rod can be adjusted, the purpose of automatically balancing the shaft rod is achieved, the length of the telescopic rod can be rapidly adjusted according to actual requirements, and the practicability is high. And the device is fixed at a required position through the locking device, and rapid stretching and locking are realized in an electric mode, so that the operation complexity is reduced.

This utility model belongs to the field of air pollution control and environmental protection, and discloses an intelligent environmental monitoring instrument for air pollution control. It includes a telescopic rod device for easy extension and retraction, and a housing for storing electrical energy and accommodating movement. The telescopic rod device is fixedly installed at the rear of the housing. The housing contains an extension device for lifting, suspending, deployment, and environmental monitoring. The housing includes a chassis body with two symmetrically mounted support legs on one end of the chassis bottom and two symmetrically mounted walking components on the end of the chassis away from the support legs. This intelligent environmental monitoring instrument for air pollution control, through structural innovation, organically combines mobility, deployment stability, and operational efficiency, solving the pain points of traditional environmental monitoring equipment such as laborious handling, time-consuming installation, and poor terrain adaptability. It is particularly suitable for scenarios requiring frequent changes of monitoring points in air pollution control, and has high practical value and promotion potential.

The utility model provides a portable asphalt crack sealing machine, which belongs to the technical field of road maintenance, and comprises a material storage component, a frame, a material storage tank fixedly connected in the middle of the frame, a support seat fixedly connected on the side wall of the upper end of the frame, and a cover plate packaged on the top of the material storage tank, and the support seat is clamped on the side wall of the material storage tank; the crack pouring assembly comprises a material pump fixedly connected to the end of a discharging port of the material storage tank, a supporting plate fixedly connected to the end of the vehicle frame, a cover body slidably connected to the lower end of the supporting plate and a main spray head fixedly connected to the middle of the cover body. The utility model has the beneficial effects that the material storage component and the crack pouring component are matched for use, and the frame is combined with the liftable cover body, so that the operation height requirements under different working conditions are met; the expansion cover is rapidly stretched out and drawn back through the sliding rail and the propelling air cylinder, a single-slit or wide-width area can be covered, and the machine is multipurpose and adapts to different crack widths.

This application discloses a high-frequency isothermal actuator and flapping wing device based on magnetic shape memory alloy, including a drive box, a fixed hinge, a movable hinge, and a bionic wing. In this application, two pairs of electromagnets are installed in four directions on the magnetic shape memory alloy rod. Compared to using springs in a magnetic shape memory alloy actuator, this achieves rapid extension and retraction of the magnetic shape memory alloy rod, resulting in higher drive precision and speed. The design is simple, avoiding the impact of excessive heat generation on the drive effect in traditional actuators or flapping wing devices, and also avoiding the complex structural design of traditional flapping wing aircraft.

The utility model discloses a mobile seedling transplanting device for mobile traditional chinese medicinal material planting, and the utility model relates to medicinal plant technology field, and the utility model discloses, including: displacement cylinder, the inner wall sliding connection of displacement cylinder has reset device, reset device resets with elastic structure, the upper portion of displacement cylinder is provided with folding device, through setting reset device and the cooperation of folding device, the sliding fit structure of displacement cylinder and push board, can accurate control the depth of seedling implanting soil, avoid the problem of traditional artificial seedling transplanting when the depth is not same. The stable push of push board can ensure that seedling root system stretches in the soil, and the combination of the neat seedling hole formed by the earth breaking piece in advance reduces the root system bending or extrusion injury, and the cooperation of folding device through the clamping block and second compression spring can realize the quick telescopic and fixed of telescopic link, and the volume is small after folding, and it is convenient for transportation and storage, especially suitable for the purpose of traditional chinese medicinal material planting area of complex topography such as mountain, terrace and the like.
