This utility model discloses a packaging box for storing fruit and vegetable preservatives, relating to the field of fruit and vegetable preservative storage technology. It includes a fruit and vegetable packaging box body, a fruit and vegetable packaging box cover, and a ventilation control component. This utility model facilitates the control of the evaporation rate and dosage of the fruit and vegetable preservatives inside the packaging box through the ventilation control component. It has a high reusability rate, a simple structure, and the fruit and vegetable packaging box body facilitates the classification and storage of the fruit and vegetable preservatives, improving space utilization and preventing damage to fruits and vegetables due to external shaking.

The utility model discloses a hydraulic floating scraping type suction head for water floating scum drag scraping collection, including the floating room casing, the both sides of floating room casing one end all are established with the propulsion groove, two propulsion grooves's inside all are fixedly installed with hydraulic propulsion subassembly, the inside rotation of floating room casing is connected with two symmetrical settings of rubbing crusher, the surface fixed mounting of floating room casing has fixed component, the utility model discloses a hydraulic floating scraping type suction head for water floating scum drag scraping collection, through setting up hydraulic propulsion subassembly and preventing resistance guide wheel, hydraulic side pusher clockwise rotation pushes the water flow and produces the right thrust, counterclockwise rotation produces the left thrust, in this way, the floating room casing is convenient for adjusting direction, and preventing resistance guide wheel plays the role of guiding transmission, adjusting torque, through the change liquid flow direction and enhances the power transmission efficiency, guarantees the suction head multi -angle stable suction water floating scum, avoids appearing floating scraping type suction head and cannot normally suck even and sinks into the bottom of the water phenomenon.

The utility model relates to a kind of purification gas ash conveying system, belong to calcium carbide furnace field.It includes: multiple ash unloading mechanisms, multiple purification cloth bag storehouse, purification total ash storehouse, purification pneumatic ash conveying storehouse pump and purification pneumatic ash conveying pipeline;Multiple for the flue agglomerate mincing ash unloading mechanism one-to-one correspondence is set in the discharge port of multiple purification cloth bag storehouse, multiple ash unloading mechanism is communicated with the purification total ash storehouse by pipeline, the discharge port of the purification total ash storehouse is communicated with the feed inlet of the purification pneumatic ash conveying storehouse pump by pipeline, the discharge port of the purification pneumatic ash conveying storehouse pump is communicated with one end of the purification pneumatic ash conveying pipeline.The utility model is favorable to avoid the plugging phenomenon in the process of ash conveying, also eliminates the risk that staff climbs on elevated to dredge pipeline, improves the safety factor of staff, reduces the labor intensity of staff.

The utility model relates to the technical field of machining, and particularly discloses a deburring device for anchor machining, which comprises a bottom plate and a four-hole anchor, the upper end of the bottom plate is slidably connected with a vertical plate through a slider and a chute, and the right end of the vertical plate is rotatably connected with a first turntable; a first worm and gear motor with the output end fixedly connected with the first rotating disc is installed at the left end of the vertical plate, the right end of the first rotating disc is fixedly connected with a rotating frame with the right side of an opening structure, and the four-hole anchorage device is located in the rotating frame. The purposes that the direction of the four-hole anchorage device and the positions of the four inner holes are convenient to adjust, a clamp does not need to be loosened and tightened repeatedly, time and labor are saved, and the working effect is improved are achieved, after rough grinding of the four inner holes is completed, the positions of a rough sand grinding head and a fine sand grinding head are exchanged, then the four inner holes of the four-hole anchorage device can be finely ground through the fine sand grinding head, and the working efficiency is improved. Therefore, the purposes that the coarse sand grinding head and the fine sand grinding head can be exchanged and used conveniently, and operation is easy and fast are achieved.
