This invention discloses a highly efficient plant protection machine for controlling major pests of cowpeas, belonging to the field of plant protection equipment technology. It includes a housing; the top of the housing is equipped with a blower assembly for blowing off diseased, withered leaves and insect-infested flowers from cowpeas; one end of the housing is equipped with a sweeping assembly for cleaning diseased and withered leaves from furrows and ridges; and the interior of the housing is equipped with a suction and crushing assembly for collecting the diseased and withered leaves after sweeping. In this invention, the blower can blow diseased and withered leaves attached to cowpea plants into furrows and ridges. Because the blower is fixedly connected to a vertical plate by a second spring, it generates a certain vibration amplitude during startup, causing it to swing. When the swinging blower touches the first springs on both sides, a reaction force is generated, causing it to return to its original position. This cyclical change in the blower's angle allows the airflow to cover a wider area of ​​the cowpea plant.

The airflow output direction adjustment device includes: a fixed base with a base inlet and a base outlet; an adjustment component with a component inlet and a component outlet, the component inlet communicating with the base outlet; and the spatial orientation of the component outlet relative to the component inlet is adjustable, allowing the flow path between the component inlet and the component outlet to be switched or adjusted by adjusting the spatial orientation of the component outlet relative to the component inlet, thereby adjusting the airflow output direction.

The water soaking mechanism for the steam boiler comprises a boiler body water tank and an air chamber, and the air chamber is fixedly installed on the top face of the boiler body water tank. The steam boiler has the advantages that the reducer pipe and the turbine are adopted, when the steam boiler works, the high-temperature smoke pipe is arranged in the boiler body water tank, water in the boiler body water tank is heated at high temperature, steam is formed by the water and then enters the bent pipe along the air inlet hopper, at the moment, the diameter of the section of the bent pipe is large, and when the steam passes through the reducer pipe, the pipe diameter of the other end of the reducer pipe is reduced; the steam flow speed is increased, so that the steam outlet flow speed of the steam inlet pipe is increased, the blowing efficiency of the turbine is improved, the rotating efficiency of the turbine is improved, the turbine drives the shaft rod and the stirring rod to rotate, water in the furnace body water tank is stirred, and the heat distribution uniformity is improved; the problem that friction loss is increased due to middle force transmission is solved, power output is direct and stable, the stirring efficiency is improved, and then the working efficiency is improved.

This application belongs to the field of fans and relates to an air inlet grille and a fan. The air inlet grille includes multiple air guide ribs arranged radially around a preset axis. Adjacent air guide ribs are spaced apart, and the ends of the multiple air guide ribs near the preset axis are connected to form an air inlet area. The air guide ribs have a windward side and a leeward side arranged opposite each other. The leeward side is provided with a flow guiding structure, and the extension direction of the flow guiding structure intersects with the extension direction of the air inlet area. In this application, by connecting the ends of the multiple air guide ribs near the preset axis to form an air inlet area, providing a flow guiding structure on the leeward side of the air guide ribs, and having the extension direction of the flow guiding structure intersect with the extension direction of the air inlet area, an air inlet area is formed in the middle of the air inlet grille. After the airflow passes through the air inlet area, it can be dispersed by the flow guiding structure to effectively reduce the vortex in the middle of the leeward side of the air inlet grille, thereby reducing noise and improving blowing efficiency.

The utility model relates to the technical field of blowing devices, in particular to an axle housing sand core blowing device. The air blowing device mainly solves the problems that when a common axle housing sand core is subjected to air blowing treatment, a layer of cloth needs to be manually laid on a mold base by a worker, meanwhile, an air pipe is held by a hand to conduct air blowing on the cloth, sand core hardening is assisted, and due to the fact that air blowing time is long, the hand of the worker is aching and pain, and hardening operation is affected. According to the technical scheme, the sand core mold comprises a sand core mold base and breathable cloth, a support and a protective cover are arranged at the top of the sand core mold base, a first driving assembly, an N-shaped frame and an air blowing assembly are arranged on the protective cover, the air blowing assembly comprises an air pump, and the air outlet end of the air pump is connected with a bent pipe. According to the automatic cloth covering device, the purpose of automatically and uniformly blowing is achieved while automatic cloth covering is achieved, manual intervention is reduced, and the blowing efficiency is improved.

This application relates to a nickel plating tank, comprising a main body and a gantry frame. The main body has alternating processing tanks and drain tanks. Mounting seats are provided on both sides of the drain tanks, and multiple air nozzles are vertically arranged on the mounting seats, positioned above the drain tanks. The gantry frame is located above the main body and is driven to connect to a plating rack. The plating rack is moved above the drain tank by the gantry frame and aligned with the air nozzles.
