This invention belongs to the field of air conditioning technology and relates to an energy-saving air conditioner for grain storage. The invention includes an outdoor unit, two filter assemblies, and a cleaning assembly. Each filter assembly includes multiple sequentially hinged filter plates, with a torsion spring at the hinge axis to give the filter plates a folding tendency. A connecting plate is connected to the upper end of the filter assembly, and a baffle is connected to the lower end. A first locking assembly is provided between the connecting plate and the outdoor unit, and a second locking assembly is provided between the baffle and the outdoor unit. By setting two filter assemblies that can work alternately, the first locking assembly unlocks the first filter assembly after the second filter assembly blocks the air inlet, allowing the upper end of the first filter assembly to move downwards, preventing dust from entering the air conditioner during the alternation of the two filter assemblies. The entire switching process does not require stopping the machine or manually disassembling the filter plates, significantly reducing maintenance frequency and labor costs, and ensuring continuous and stable control of the grain storage environment.

The utility model discloses a kind of water supply regulating valve stem anti-deflection devices, comprising: with the support fixed connection of external support supporting member;Length direction and the axial parallel arrangement of valve stem guiding member, with the fixed connection of supporting member, and is equipped with first guide part;With the fixed connection of the valve stem tight component, is equipped with second guide part, the second guide part cooperates with the first guide part, and the movement path of the tight component is limited. The cooperation of the second guide part of the tight component setting and the first guide part of guiding member setting, the movement path of the tight component is limited, so as to limit the movement path of valve stem, ensure the direction stability in the operation process of valve stem, prevent damage key measuring component.

The invention relates to the technical field of wormwood planting equipment, in particular to harvesting equipment for large-area wormwood planting, and solves the problem that wormwood quality is reduced due to the fact that wormwood is rubbed and folded by a conveying system.The harvesting equipment comprises a second supporting frame, a slope aligning plate and a slope seat, and supporting rotating rods are movably mounted at the two ends of the second supporting frame; a center rod rotationally penetrates through the position between the ends, close to each other, of the two supporting rotating rods, the center rod is fixedly installed in a fixing frame, the fixing frame is movably installed in the second supporting frame in the direction perpendicular to the second supporting frame, and first power assemblies are installed at the lower ends of the two supporting rotating rods correspondingly; according to the device, wormwood can be actively pulled, cut, subjected to weed removal, conveyed, divided into locks, divided and thrown, the wormwood is only lodged and cut front and back, steering and transverse conveying are not needed, the wormwood cannot be rubbed and folded, and the quality of the wormwood is guaranteed.

The utility model discloses a fluorine-lined centrifugal pump, and relates to the technical field of centrifugal pumps. The device comprises a pump body, a liquid discharging unit used for discharging high-temperature corrosive substances is arranged on one side of the pump body, and an expansion tank in the liquid discharging unit is arranged below the pump body and communicated with the pump body; the cooling piece is arranged on the inner wall of the expansion tank; and the discharging piece is arranged in the expansion tank. According to the device, the liquid discharging unit is arranged, the volume expansion tank can contain high-temperature corrosive liquid remaining on the pump body, the cooling piece can cool the liquid, and the atomization phenomenon generated when the liquid is discharged is reduced. The two electromagnetic valves are arranged, so that accurate control over liquid inlet and outlet is achieved, the problem of atomization sputtering when an existing fluorine-lined centrifugal pump discharges residual liquid is effectively solved, the safety of operators is guaranteed, and the use safety and reliability of equipment are improved.

The present application belongs to the technical field of medical devices. In view of the deficiencies of the prior art, the present application provides a femur positioning device for knee replacement, which comprises a base, a thigh support part, a popliteal fossa support part, a lower leg support part, an extension guide rod and a multi-stage drilling guide mechanism arranged on the base; wherein the multi-stage drilling guide mechanism is arranged at the end of the extension guide rod away from the thigh support part. The femur positioning device for knee replacement provided by the present application can perform multi-stage guiding on the surgical instruments used for drilling. The extension guide rod, the thigh support part and the popliteal fossa support part cooperate with each other to automatically make the drilling direction always parallel to the patient's femoral axis, prevent the drilling direction from deviating, realize one-stage guiding, and the multi-stage drilling guide mechanism can also perform two-stage guiding on the surgical instruments used for drilling, further stabilize the surgical instruments used for drilling, improve the stability of the surgical instruments used for drilling in the drilling operation, and improve the surgical effect.
