The invention discloses a 9Cr2Mo straightening roll heat treatment method based on an exhausting and quenching process and belongs to the field of straightening roll processing. The 9Cr2Mo straightening roll heat treatment method comprises the following steps: sealing the central hole and the end surfaces of a roll body with a quenching tool, and arranging an expansion ring between an upper pressing plate and a clamp nut to form effective sealing; during quenching treatment, first preheating the roll body, then exhausting high-temperature gas from the central hole, and next, heating the roll body; and during quenching, first performing repeated lifting water quenching, then immersing the roll body in oil to cool the roll body, and finally performing tempering repeatedly. According to the 9Cr2Mo straightening roll heat treatment method, negative pressure is generated in the central holes of the roll body, so that a quenching medium cannot enter the end surfaces and the central hole; and after being quenched, the roll body has high external hardness and good internal toughness, so that cracks are effectively avoided.

The invention relates to the technical field of electric power transmission and discloses a cooling wire for a motor.

The hollow block is divided by the sliding plate into an upper cavityand a lower cavity, the upper cavity and the lower cavity communicate through a slit arranged on the vertical shaft, and the lower cavity communicates with the through hole. The inner cavity is provided with a driving plate which is vertically and slidingly connected to the hollow column. The driving plate is provided with an air outlet check valve communicating with the upper cavity, an air inlet check valve which is fixed to the hollow column and communicates with the outside is arranged under the driving plate. The driving plate and the sliding plate are fixedly connected by a connection rod which is internally provided with an airway which communicates with the upper cavity and the outside. The cooling wire for a motor has a simple structure and can continuously cool the conductor inthe wire to avoid the burning of the wire.

The invention relates to the field of door and window processing, in particular to installation equipment for aluminum alloy door and window sealant strips, including a placing platform, above which a moving frame and a drive mechanism for driving the moving frame to reciprocate laterally are arranged, and the moving frame is provided with two The compression wheel is fixedly connected with a correction block, and the correction block is provided with a through groove for the rubber strip to pass through. The cross-sectional shape of the through groove is "concave". The frame is provided with a first air cylinder for driving the pressing wheel to approach or move away from the placing table. This scheme realizes that the rubber strip is automatically installed in the slot hole on the aluminum alloy door and window.

The invention discloses an automatic wound irrigation device. The automatic wound irrigation device comprises an irrigation pipe and a guide pipe, and the inlet end of the irrigation pipe is communicated with the outlet of a water supply container; the inside of the water supply container is provided with a pressurizing device; the outlet end of the irrigation pipe is arranged inside a wound, normal saline can flow out of the outlet end of the irrigation pipe into the wound to form a liquid flow environment as well as maintain a preset liquid pressure inside the wound, and accordingly a high-pressure area can be formed; the inlet end of the guide pipe is arranged inside the wound, and the outlet end of the guide pipe is communicated with a recovery container, inside which a negative-pressure device is arranged for forming a vacuum environment inside the recovery container; the vacuum environment inside the recovery container can form a low-pressure area inside the wound via the inlet end of the guide pipe; the normal saline flowing out of the outlet end of the irrigation pipe flows from the high-pressure area to the low-pressure area and meanwhile irrigates the wound; drainage liquid formed after wound irrigation can enter into the inlet end of the guide pipe and flow into the recovery container via the outlet end of the guide pipe.

The invention discloses a seeding robot. The seeding robot comprises a rack, a lifting seeding conical rod, a limiting sleeve, a crankshaft, a motor and a storage battery, wherein the limiting sleeveis fixedly arranged in the rack; the lifting seeding conical rod is inserted in the limiting sleeve; the upper end of the lifting seeding conical rod is connected with a connecting-rod curved neck ofthe crankshaft; a rotary gear is arranged on the crankshaft; a motor gear is arranged on a rotary shaft of the motor, and is meshed with the rotary gear; the motor is connected with the storage battery. A seeding channel is arranged in the lower part of the lifting seeding conical rod, an upper-end seeding inlet of the seeding channel is formed in a middle rod wall of the lifting seeding conical rod, a lower-end seeding outlet of the seeding channel is formed in a conical head of the lifting seeding conical rod, the limiting sleeve is provided with a through hole corresponding to the upper-endseeding inlet, and the outer side of the through hole is connected with a hopper by a guide pipe.
