The utility model belongs to the field of freshwater pond culture, and particularly relates to a freshwater pond culture aerator which comprises an L-shaped supporting plate. A mounting plate is fixedly connected to the top of the L-shaped supporting plate, a driving motor is arranged on the front face of the mounting plate, a transmission rod is fixedly connected to the output end of the driving motor, and a driving assembly is connected to one end of the transmission rod; the driving assembly comprises a toothed shaft A fixed to one end of the transmission rod, the toothed shaft A is in transmission connection with a toothed shaft B through a toothed belt, and a directional hole is formed in the toothed shaft B; through the toothed belt transmission design of a toothed shaft A and a toothed shaft B in the driving assembly, the synchronous rotation function of a stirring ring and a long oxygen conveying pipe is achieved, the problem that the oxygen dissolving efficiency is low due to the fact that stirring and oxygen conveying positions of a traditional aerator are separated is solved, the stirring ring stirs water flow to enable oxygen to be evenly diffused, and the oxygen dissolving efficiency is improved in combination with micropore release of an oxygenation head.

This utility model discloses a vegetable drying conveyor belt cleaning device, which relates to the field of vegetable conveying technology. The device includes a support frame, with a conveyor belt for transporting vegetables mounted inside the support frame. A mounting frame is fixedly installed on one side of the bottom of the support frame. It also includes a high-temperature sterilization mechanism, which includes a cleaning roller mounted inside the mounting frame. By using a water pump, spray plate seat, cleaning roller, conveying pipe, motor, and heating pipe in conjunction, the device achieves contact cleaning of the conveyor belt surface. This solves the problem of the conveyor belt in the drying room generating sugary sap and adhesive force that causes vegetable debris to stick, easily leading to conveyor belt contamination. Simultaneously, the heating pipe, in conjunction with the spray plate seat, enables the use of high-temperature water to disinfect and sterilize the cleaning roller.

The utility model discloses a boar semen incubator, and relates to the technical field of semen storage. The boar semen incubator comprises a box body, a cover is movably installed on one side of the top of the box body through a hinge, an auxiliary fixing mechanism used for conducting auxiliary fixing on boar semen storage test tubes is fixedly installed on the top of the cover, and an extending protection mechanism is fixedly installed on one side of the bottom in the box body. The horizontal state of the device is monitored in real time through power-on operation of an inclination sensor, and when the inclination sensor monitors that the horizontal state of the device exceeds a preset value of the inclination sensor, the inclination sensor controls a first electromagnetic valve pipe to be powered on to be opened, so that high-pressure air in an air tank is conveyed into an air bag, and the air bag expands in volume; the outer side of the device can be protected through the air bag with the expanded volume, the effect of buffering the impact force generated by falling and toppling of the device is achieved, and the function of safety protection of the boar semen test tube is achieved.

The utility model belongs to the field of electric tools, and particularly relates to a lithium battery high-power chain saw with good safety performance, which comprises a main body, a movable protective device is arranged on one side of the main body, and the movable protective device comprises a protective part for protective operation and an adjusting part for protective adjustment; the protective part comprises two movable rods, a plurality of protective steel rings are fixedly mounted at the tops of the movable rods, limiting frames are fixedly mounted on the two sides of each protective steel ring, the bottoms of the two limiting frames are fixedly mounted at the tops of the movable rods correspondingly, and protective plates are fixedly mounted at the tops of the movable rods correspondingly; the protective steel ring at the top of the movable rod can effectively block splashed wood chips and sundries in the cutting process, the limiting frame and the supporting plate guarantee stable installation of the protective steel ring, the limiting head prevents the movable rod from moving excessively, the safety protection function on operators is achieved, the problem that the splashed wood chips and sundries are prone to hurting the operators is solved, and the safety of the operators is improved. And the safety of chain saw operation is improved.

The utility model discloses a forging press with a protective effect, which relates to the technical field of forging presses and comprises a base, guide posts equidistantly arranged at four corners of the top surface of the base, a top plate arranged on the top surfaces of the guide posts, a hydraulic press arranged in the middle of the top surface of the top plate, a slider sleeved on the guide posts, and a protective cover arranged on the slider. The top surface of the slider is fixedly connected with an output shaft of the hydraulic machine; through the cooperation of the enclosure arranged between the base and the top plate, the hinged opening and closing door and the explosion-proof glass, splashing chippings and cracking forgings can be conveniently stopped, a protective barrier is provided for operators, the operation safety is improved, and the safety protection function is further achieved; and by means of the handle, quick opening and closing are facilitated, use convenience is improved, the function of flexibly entering and exiting an operation area is achieved, the problem that a traditional forging press is open and lacks protection is finally solved, and safety and production efficiency are improved.
