The backlight direct display module comprises a cover plate, one side of the back face of the cover plate is directly connected with the backlight module into a whole, and a liquid crystal display module is not arranged between the cover plate and the backlight module. The cover plate structurally comprises a cover plate body, a black shading ink layer and a semi-permeable ink layer which are stacked in sequence; the black shading ink layer covers partial area of the back surface of the cover plate body, and the area, not covered by the black shading ink layer, of the back surface of the cover plate body forms a plurality of hollow areas, so that the cover plate forms a display area and a non-display area; the semi-permeable ink layer covers the black shading ink layer and the plurality of hollow areas; the backlight module comprises a plurality of LED lamps which are independently controlled; a light-emitting side of the backlight module is provided with a light-shielding layer used for being attached to the cover plate, and hollowed-out parts are arranged on the light-shielding layer and correspond to the hollowed-out areas in position. According to the utility model, the performance of the display module is improved and the manufacturing cost is reduced while the simple display requirement is met.

The application relates to the technical field of edible fungus inoculation, and in particular to a chondrostereum bag inoculation device, which comprises a supporting frame and an inoculation device, the inoculation device comprises an inoculation box fixedly connected to the top of the supporting frame; two sealing plates are arranged in the scheme; after a fungus bag enters the inoculation box, the sealing plates are lowered to the bottom to form a completely closed space, the inoculation process is isolated from the open environment, bacteria spores (such as penicillium and aspergillus) in the air can be avoided from falling into the opening of the fungus bag or the inoculation position, the inoculation needle is made of soft silica gel material, can be slightly deformed with pressure when being inserted into the fungus bag, rigid extrusion and scratch of chondrostereum mycelium caused by traditional metal needles are avoided, the electromagnetic valve and the spiral blade are matched with the elastic sealing valve to send the seed cylinder, quantitative conveying is realized, growth differences caused by too much inoculation (intense nutrition competition) or too little inoculation (mycelium is difficult to quickly occupy space) can be avoided, strain waste caused by excessive inoculation is avoided, and the raw material cost can be significantly reduced in the long term.

This utility model discloses a molten iron sampling device for a blast furnace ladle station, belonging to the technical field of metallurgical automation equipment. It includes a base, a column, a horizontal beam frame, a traveling trolley, a vertical sampling frame, a sampling drive motor, a floating frame, a sampler, and a temperature sensor. The column is installed on the base, the horizontal beam frame is installed on the column and extends horizontally, the traveling trolley is installed on the horizontal beam frame and moves horizontally along the beam frame, the vertical sampling frame is installed on the traveling trolley, the sampling drive motor is installed on the traveling trolley and drives the vertical sampling frame to move vertically, the floating frame is installed on the vertical sampling frame, and the sampler and temperature sensor are installed on the floating frame. The vertical sampling frame is equipped with a position sensor. This molten iron sampling device for a blast furnace ladle station has multiple advantages, including high degree of automation, good sample representativeness, high success rate, time saving, reduced labor intensity, and improved operational safety, significantly improving the efficiency and quality of the molten iron sampling process.
