The invention discloses a civil engineering concrete mixer feeding device convenient to clean, and particularly relates to the technical field related to concrete.The civil engineering concrete mixer feeding device comprises a base, a steel structure frame is fixedly installed in the middle of the upper end of the base, a pouring funnel is fixedly installed on the upper portion of the steel structure frame, and a conveying mechanism is arranged on the lower portion of the steel structure frame; a screening mechanism is arranged between the conveying mechanism and the pouring funnel, and a cleaning mechanism is further arranged on the upper side of the conveying mechanism on the front portion of the steel structure frame. According to the convenient-to-clean concrete mixer feeding device for civil engineering, concrete raw materials fall on the surface of a screening grid, stone blocks which do not conform to specifications can be screened out, and due to the synchronous rotation of a pushing roller and a spiral stirring roller, caked sand or concrete can be scattered while the caked sand or concrete is scattered; and the screened stones are pushed backwards into the receiving box and are treated in a centralized manner, so that the quality of concrete produced by the concrete mixer is improved, and the practicability of the device is also improved.

This invention belongs to the field of geological exploration technology and discloses a geophysical instrument for geological exploration, including a base plate and a movable and fixed assembly. The base plate is connected to a gear ring and a sun gear, the sun gear is connected to an adjustment handle and a planetary gear, and the planetary gear is coaxially connected to a detection device and a limiting handle. The base plate has an adjustment hole. The movable and fixed assembly includes a connecting plate, which connects to a level and a telescopic assembly. The telescopic assembly includes an upper sleeve, a lower sleeve, a rotating handle, a ball screw assembly, and a bevel gear set. The lower sleeve is connected to a connecting shaft, the connecting shaft has a traveling wheel and a stabilizing shaft, and the stabilizing shaft is connected to a support plate. This invention solves the problems of existing mobile geophysical instruments, such as the inability to adjust the moving device, poor mobility in the field, poor stability of the entire device during geophysical exploration, and the lack of intervention on branches or grass around the detection area, which can easily affect the normal use and accuracy of the detection equipment. It is suitable for geological exploration.

The utility model relates to the technical field of hammering element structures for crushers or crushers, and discloses a material moving hammer for a crusher or crusher, a crusher and a crusher. The material moving hammer for the pulverizer or the crusher comprises a hammer body, a shaft hole is formed in the hammer body, the hammer body is provided with a material moving face and a crushing face, the material moving face is located in the lateral direction of the hammer body, the crushing face is located at the end of the hammer body, and the material moving face and the crushing face are arranged in a grounded mode. And a hard alloy block is embedded in the base body of the hammer body and is arranged close to the material moving surface. By embedding the hard alloy block in the hammer body, the structure of the hammer body and the design of the crushing surface are optimized, so that the wear resistance is improved, the fracture risk is reduced, the crushing effect is optimized, the service life is prolonged, and meanwhile, the operation safety is also improved.

This utility model relates to the field of sampling cone cleaning technology, and discloses a cleaning device suitable for sampling cones, including a housing. A servo motor is fixedly installed on the inner front wall of the housing by a pad. A gear is fixedly sleeved on the output shaft of the servo motor. A gear ring is meshed on the outer surface of the gear. A hollow rotating shaft is fixedly sleeved inside the gear ring. The hollow rotating shaft is rotatably connected to the front end of the housing. A rotating rod is provided at one end of the hollow rotating shaft. This utility model uses nylon bristles to penetrate deep into the cone hole for physical friction. Cleaning liquid is atomized from a liquid nozzle to cover and dissolve stains. Compressed air is blown away by an air nozzle to remove residues. This multi-dimensional and rapid removal of deposits can minimize the risk of physical damage to the sampling cone, significantly improve cleaning efficiency and speed, reduce the difficulty of operation and the skill requirements of the operator, reduce human error, reduce instrument performance fluctuations caused by cleaning differences, reduce accidental damage and replacement frequency of the sampling cone, and save consumable costs.

This utility model relates to the field of steel metallurgical equipment technology, specifically disclosing a precise control device for the stroke of a hydraulic shear in a billet continuous casting machine. It includes a limiting component located on the upper shear blade seat and a triggering component located on the lower shear blade seat. The limiting component includes a first fixed plate, a limiting body, and a contact head. The first fixed plate is fixedly connected to the upper shear blade seat, the limiting body is mounted on the fixed plate and has an internal mounting cavity, and the contact head is slidably located within the mounting cavity and connected to the hydraulic shear control circuit via an electrical wire. This 45° suspended hydraulic shear limiting device has a simple structure, low cost, and is easy to manufacture. It can operate stably in harsh environments. The contact head relies on self-realignment to ensure reliable signal transmission and effectively avoids fatigue fracture of the piston rod fixing bolts caused by excessive shear stroke of the hydraulic cylinder, extending the service life of the hydraulic cylinder, reducing the frequency of spare parts replacement, saving costs, and reducing the labor intensity of employees.
