The invention provides a bottom-holding protection balancing device of a bridge fabrication machine, which belongs to the technical field of continuous beam construction and is mounted on a truss of the bridge fabrication machine, and the bridge fabrication machine is positioned on a non-overline construction side and comprises a truss connecting part, a clamping part and a counterweight connecting part. Wherein the truss connecting part is arranged on the truss in a sleeving manner. The clamping part is vertically arranged on the truss connecting part in a sliding mode and located below the truss, and a space used for containing the truss is defined by the truss connecting part and the clamping part. And the counterweight connecting part is connected with the clamping part through a counter-force assembly and is used for hanging a counterweight. When the counter-weight object generates downward acting force on the counter-weight connecting part, the counter-force assembly generates upward acting force on the clamping part, so that the clamping part ascends and abuts against the truss. According to the bottom-holding protection balancing device of the bridge fabrication machine, the balance force generated by the counter weight is utilized, the requirement for balanced and symmetrical construction of cantilever sections can be met, and meanwhile a complete bottom-holding protection device does not need to be additionally installed.

The invention relates to the technical field of conveying and cooling, in particular to a cooling bed roller bed with a lifting type split quenching bed, which comprises a horizontal main frame and a roller mounted at the upper end in the horizontal main frame, and an electric control lifting type water collecting cover is assembled in the horizontal main frame in a sliding manner. According to the cooling bed roller way with the lifting type split quenching bed, a boss is formed on the periphery of a metallurgical product by adopting the electric control lifting type water collecting cover designed in a lifting type structure, and then the overhead water collecting cover is used for rapidly discharging liquid to form a high-position quenching pool for quenching the product; the whole operation process does not need to operate and control the product, so that the stability of the quenching process is improved; the lateral longitudinal transition groove is closed by turning over the electric control type lateral closing cover plate, and the waterproof performance of the outer side can be guaranteed while lifting of the electric control lifting type water collecting cover in the horizontal main frame is not affected. The electric control lifting type water collecting cover is in an idle state during lifting and is in a full-load state during descending, so that the lifting energy consumption can be greatly reduced.

The scheme discloses a mildewy dregs treatment method in the technical field of brewing, which comprises the following steps: step one, using hot water above 95 DEG C to disinfect and kill the mildewy dregs with 95 DEG C; step two, putting the disinfected and killed mildewy dregs into a retort to steam for 20-40 min, taking out the steamed mildewy dregs to spread and air, to thresh, and to fold after the mildewy dregs are cooled; step three, putting the folded mildewy dregs into the retort to steam for 20-40 min after 5-8 h, taking out the steamed mildewy dregs to spread and air, to thresh, and to fold after the mildewy dregs are cooled; step four, repeating the operation of step three for 1-3 times to obtain the treated mildewy dregs. Through the mildewy dregs treatment method, the mildewy dregs can be effectively removed, and the mildew can be completely killed.

The invention relates to a machining device and method for rapidly machining a double-angle hole, a base (1) is provided with a base angle (alpha), the base is provided with a positioning bush used for positioning a part (100) on an inclined plane (302), a support (15) is vertically arranged on the base (1), a drill plate (19) is arranged on the support (15), the drill plate (19) is provided with a drill bushing (16), a through hole of the drill bushing (16) is vertically arranged, and the through hole of the drill bushing (16) is provided with a through hole of the drill bushing (16). A distance (L1) is formed between the center line A of the drill bushing (16) and the center line B of the positioning bushing, a distance (L2) is formed between the center C of the drill bushing (16) and the horizontal center line D of the part, and the base angle (alpha), the distance (L1) and the distance (L2) are obtained by the angle of the double-angle hole. The production efficiency of parts and the reasonable utilization rate of equipment can be improved, and the occupancy rate of unnecessary public efficient equipment and the part machining cost are reduced.

The invention discloses a fertilization device based on different elements for tea planting, and relates to the technical field of tea planting, comprising a storage bin, wherein two handle rods are fixedly connected to the outer surface of the storage bin, a guide pipe is fixedly connected to the bottom end of the storage bin, and a quantitative unloading mechanism is arranged inside the storage bin, wherein the quantitative unloading mechanism comprises an anti-blocking pre-unloading unit, and the anti-blocking pre-unloading unit is arranged inside the storage bin. According to the fertilization device based on different elements for tea planting, the anti-blocking pre-unloading unit is arranged, so that the solid granular fertilizer in the storage bin can be properly stirred, and the solid granular fertilizer can be prevented from dampening and agglomerating to a certain extent, and the rotating spiral blades can prevent the accumulation and jamming of solid granular fertilizer at the connection point between the storage bin and the guide pipe, and at the same time gradually guide the solid granular fertilizer to the inside of the guide pipe, so as to ensure that a sufficient amount of temporary solid granular fertilizer can be continuously stored in the guide pipe.
