The invention provides an airtight type livestock ultra-clean breeding cabin, and belongs to the breeding field. The airtight type livestock ultra-clean cultivating cabin comprises a cabin body, a dwelling bed, a water drinking device, a feeding device, a feces removal device and an air interchanger, the cabin body is airtight, a cavity is formed inside the cabin body, the dwelling bed, the water drinking device, the feeding device and the feces removal device are all arranged in the cavity, the dwelling bed is in a net shape or grid shape, the feces removal device is arranged below the dwelling bed, the water drinking device and the feeding device are arranged above the dwelling bed, and the air interchanger is communicated with the cavity. Livestock bred in the airtight type livestock ultra-clean breeding cabin is isolated from the external environment, disease causes can not easily enter the interior of the cabin body, the sickening probability of the livestock is greatly lowered, the use medicine amount is relatively reduced, and produced meta, produced eggs and produced milk are safe.

The invention provides a waterproof new energy vehicle motor based on stable output. The waterproof new energy vehicle motor comprises a motor body, a motor front end shell, a motor rear end shell, amotor shell, a seam waterproof mechanism for preventing water from entering the motor front end shell and the motor rear end shell and a shell water guide and heat dissipation mechanism for large-areacooling and waterproofing. The motor front end shell and the motor rear end shell are fixedly connected at the front and rear ends of the motor shell respectively. The motor body is fixedly installedinside the motor shell. The invention relates to the field of new energy. According to the waterproof new energy vehicle motor based on stable output, cooling is performed by the wind force is generated by utilizing the bump in the driving process of the vehicle with the help of rain and wind; meanwhile, the gap is additionally arranged to improve the heat dissipation effect while being waterproof so that the problems of damage to the motor and influence on the stable output of the motor caused by lead winding at the motor end cover used by the general new energy vehicle, the expansion of theend cover caused by heat accumulation and rainwater infiltration into the motor in rainy days can be effectively solved.

The invention provides a novel high-pressure two-position two-way straight-through type mechanical pneumatic control valve. The novel high-pressure two-position two-way straight-through type mechanical pneumatic control valve comprises a pneumatic control valve body, a pneumatic control valve shaft mounted in the pneumatic control valve body, a top shaft rolling bearing for driving the pneumatic control valve shaft, a piston and a connecting shaft connecting the pneumatic control valve shaft with the piston, wherein a valve shaft air hole is formed in the connecting shaft; a flat valve shaft air-closing end surface is arranged on the connecting shaft; the valve shaft air hole and the valve shaft air-closing end surface are arranged on the same plane; when the pneumatic control valve shaft slides left and right, the ventilating and the closing of the air are controlled; the valve shaft air hole is sealed by an air inlet sealing ring at the upper part and an air outlet sealing ring at the lower part, wherein a sealing clearance between the valve shaft air hole and the air inlet sealing ring can be changed by adjusting a first adjusting screw, and a sealing clearance between the valve shaft air hole and the air outlet sealing ring can be changed by adjusting a second adjusting screw; an air inlet valve opening and an air outlet valve opening are respectively formed above and below the valve shaft air hole. The novel high-pressure two-position two-way straight-through type mechanical pneumatic control valve solves the problems that a zigzag air path is formed by misalignment of an air inlet and an air outlet of a conventional pneumatic control valve, and the space of an air chamber is small, so that the pneumatic control valve can bear high air pressure under high pressure and at high speed, is smooth in ventilating and has the advantages of small resistance force, high efficiency, good sealing property, and stable work.

The invention discloses a handheld four-travel engine lubrication system. The handheld four-travel engine lubrication system comprises an oil storage chamber (1) formed by a bottom case (32) and a lower tank (31), a crank shaft chamber (2) formed by the lower tank (31) and an upper tank (33), a valve chamber (3) which is formed by the upper tank (33) and a cylinder head cover (36), a cam chamber (37), and a tappet rod chamber (30); first and second oil inlet passages (12,13) which are communicated with the oil storage chamber (1) and the crank shaft chamber (2) are correspondingly formed on two sides of the upper and lower tanks (33,31); the first and second oil inlet passages (12,13) are correspondingly provided with first and second check valves (44,45); the first oil inlet passage (12) is connected with a hose (40) which is adhered to the bottom case (32); the head of the hose (40) is provided with a first oil suction port (9); the first oil inlet passage (12) is provided with a second oil suction port (10); and the second oil inlet passage (13) is provided with a third oil suction port (11). Therefore, the handheld four-travel engine lubrication system has the advantages of simple and reasonable structure, high circulation speed, high lubrication efficiency, and the like, and can separate oil and gas well and stably work in any posture.
