The utility model discloses a kind of for ploughing and scraping field ploughing and scraping field ploughing device, it is related to ploughing and scraping field ploughing device technical field, including fixed frame, the upper end surface of fixed frame is fixedly provided with connecting rod assembly, connecting rod assembly is used to connect tractor rear tow bar;The both sides of fixed frame are bolted with fixed frame, and the bottom end of fixed frame is limit slidingly provided with arc-shaped scraper.The axial displacement of screw rod is generated by thread cooperation, to drive arc-shaped scraper lifting;The sliding fit of slide bar and fixed frame ensures that scraper vertical motion, spring provides elastic support and buffers impact, and limiting plate then restricts maximum stroke.When manual fine adjustment, operator rotates rotating ring can be accurate control scraper height, whole process transmission is stable, positioning is accurate.This manual fine adjustment mode has the advantages of simple structure, reliable, high adjustment accuracy, without external power, adapt to complex environment in field etc., set position is kept stable by mechanical self-locking, especially suitable for frequently fine adjustment of tillage working condition.

The invention relates to the technical field of dune buggies, in particular to a damping connecting structure of a dune buggy, which comprises a frame, a suspension and a damping device, the suspension is hinged to the frame, the damping device is arranged between the suspension and the frame, one end of the damping device is hinged to the suspension, and the other end of the damping device is hinged to the frame; the damping device comprises an inner rod, an outer rod and a piston; the piston is fixed with the inner rod, so that a first floating oil cavity is formed between the piston and the first end of the first channel; the protection piece is fixed with the inner rod and is in sliding sealing fit with the outer rod along the axial direction; a closed second floating oil cavity is formed in the protection piece and communicates with the first floating oil cavity through the gap. The elastic piece is used for providing elastic force so that the inner rod and the outer rod tend to be far away from each other in the axial direction; the flowing of the lubricating oil does not need extra power, and the acting force generated by the damping device in the damping process is partially converted into energy for pushing the lubricating oil to flow.

The utility model relates to the technical field of waste gas collecting covers, and provides a rare earth electrolysis waste gas collecting cover which comprises a first gas inlet pipe, a first fixing frame is fixedly connected to the first gas inlet pipe, a first rotating shaft is rotatably connected to the first fixing frame, and a wind wheel is fixedly connected to the first rotating shaft. The end, away from the first fixing frame, of the first rotating shaft is fixedly connected with a connecting plate, the connecting plate is rotationally connected with a second rotating shaft, one end of the second rotating shaft is fixedly connected with a first gear, the first gear is in meshed connection with a second gear, and the second gear is fixedly connected with a second fixing frame. According to the utility model, gas moving at a high speed drives the wind wheel to rotate, the gear I rotates to be meshed with the gear II to rotate, the gear I rotates to drive the roller to rotate, and the roller rotates to drive the brush to rotate, so that the roller rotates around the rotating shaft I, and the brush rotates to sweep waste gas impurities attached to the gas inlet pipe I into the dust collection box, thereby saving manpower; and external power is not needed, environmental protection is achieved, and working efficiency is improved.

This invention discloses a quick-release CNC machine tool fixture, comprising a fixed base, a quick-change worktable, and a mobile fixture trolley. The fixed base is mounted on the machine tool worktable and includes a lower positioning part and a passive locking component. The quick-change worktable includes an upper positioning part and an automatic locking assembly. The mobile fixture trolley includes a storage unit and a worktable transfer mechanism. The automatic locking assembly includes a housing, a drive column, a spring, and a locking ball; the passive locking component is a locking column with a locking recess. When the quick-change worktable is pressed against the fixed base, the locking column inserts into the locking groove, and the spring pushes the drive column to engage the locking ball in the locking recess, achieving self-locking. When the worktable transfer mechanism lifts the quick-change worktable, the drive column moves upward, and the locking ball disengages from the locking recess, achieving unlocking. The storage unit is a rotating multi-layer storage rack, and the worktable transfer mechanism uses a hook to grasp a lifting ring and cooperates with an electric cylinder and a lateral drive component to complete the transfer. This invention achieves quick and automatic fixture replacement.

This application relates to a cable distribution box with a moisture-proof and heat-dissipating structure, belonging to the field of electrical equipment technology. It includes a condensate collection structure located inside the box, which guides and collects condensate generated within the box through a V-shaped groove, a top water guide groove, a vertical water guide groove, and an annular water collection groove, with each part's inner wall coated with a hydrophilic coating; a heat dissipation module located outside the box; and a flow guiding component for transporting condensate from the condensate collection structure to the heat dissipation module, the flow guiding component including a hollow flow guiding column, a filter ring, and an air bladder ring. The heat dissipation module transports the condensate to the evaporation tank of the heat dissipation fins through a capillary core, flexible rubber tube, etc., and discharges the condensate to the outside through evaporation. This application achieves effective guidance and collection of condensate within the cable distribution box, and discharges it through evaporation, thus achieving the technical effect of moisture-proof and heat dissipation.

This invention relates to an automatic belt conveyor with a deviation correction mechanism, comprising a main body, a drive mechanism, an idler roller mechanism, and an automatic deviation correction mechanism. The automatic deviation correction mechanism is located on the front and rear sides of two main crossbeams and includes a deviation correction fixing frame, an upper frame assembly, two braking assemblies, two deviation correction flat idlers, and two side idlers. The deviation correction fixing frame is mounted on the two main crossbeams, and the deviation correction frame body is mounted on the fixing frame via a central vertical pin. The two deviation correction flat idlers are mounted on the deviation correction frame body and can rotate freely. The brake seats of the braking assemblies are connected to the deviation correction frame body via horizontal pins, and the inner side of the brake seats extends to the corresponding deviation correction flat idlers. Damping blocks are mounted on the brake seats and used to brake the rotating deviation correction flat idlers. The side idlers are vertically mounted on their respective support seats and can rotate freely. This invention has a reasonable structure and can automatically correct belt deviations during the conveying process, greatly reducing the maintenance frequency of the belt conveyor and improving operational reliability and conveying efficiency.
