The Chinese yam harvesting and sowing machine comprises a vehicle body, a power system, a ditching device, a sowing device and a soil shoveling and backfilling device, the ditching device comprises a mounting frame arranged at the front end of the vehicle body and two furrow openers symmetrically arranged on the mounting frame, and the furrow openers can be driven to swing on the mounting frame; the sowing device comprises a seed storage box used for storing seeds and a conveying assembly used for conveying the seeds into furrowed soil, a sowing opening is formed in a bottom plate of the vehicle body, and the conveying assembly conveys the seeds into the furrowed soil through the sowing opening; the soil shoveling and backfilling device comprises soil shoveling plates arranged on the two sides of the vehicle body, the soil shoveling plates are located behind the seeding openings in the vehicle body, and the soil shoveling plates can be driven to deflect longitudinally and transversely to shovel soil; by integrating a plurality of functions of ditching, seeding, shoveling and backfilling and the like, the operation efficiency is remarkably improved, the time and labor cost are saved due to the one-time operation function, and the production is more convenient and efficient.

The invention discloses a swab detection self-service system, which comprises an identity recognition module, a sample collection management module, a swab detection module and a swab detection module, and is characterized in that the identity recognition module is used for recognizing a user identity in a manner of combining a biological characteristic recognition technology and intelligent card recognition, and the module recognizes user identity information and transmits the user identity information to the sample collection management module; the sample collection and management module comprises an intelligent swab grabbing device and a swab positioning and guiding mechanism, the intelligent swab grabbing device adopts a high-precision mechanical arm, the positioning precision error of the intelligent swab grabbing device does not exceed 0.1 mm, and the detection and analysis module adopts a molecular detection technology to analyze a collected sample and transmits a detection result to the result feedback and storage module; according to the invention, by adopting an identity recognition mode of combining a biological feature recognition technology and smart card recognition, the accuracy and efficiency of identity recognition are improved, the complexity and errors of traditional identity recognition are reduced, a user can enter a detection process more quickly and accurately, and the convenience and overall efficiency of detection are improved.

This invention discloses an integrated precast shear wall, belonging to the field of shear wall technology. It aims to solve the technical problem that workers may need to repeatedly adjust the position of the shear wall to ensure that each steel bar on the ground is inserted into the sleeve of the shear wall, leading to a cumbersome adjustment process and reduced construction efficiency. The invention includes a shear wall body, inside which are arranged multiple main structural transverse steel bars, multiple secondary structural transverse steel bars, multiple main structural longitudinal steel bars, multiple secondary structural longitudinal steel bars, and multiple sleeve grouting components. The secondary structural transverse steel bars are connected to the main structural longitudinal steel bars via connecting bars. The bars of the main structural transverse steel bars are tied together with the bars of the main structural longitudinal steel bars and the secondary structural longitudinal steel bars. The sleeve grouting components include a longitudinal cylinder and multiple transverse cylinders, with a grouting inlet pipe and a grouting vent pipe connected to the outer wall of the longitudinal cylinder. This invention reduces the difficulty for workers in adjusting the position of the shear wall body, making the adjustment process easier and improving work efficiency.

This invention discloses a bearing manufacturing and pressing device with a fixed structure and its usage method, comprising a base structure, a collecting structure, a buffer structure, a driving structure, an oil storage structure, and a pressing structure. The inner wall of the base structure is fixedly connected to the outer wall of the collecting structure, the inner bottom wall of the collecting structure is fixedly connected to the bottom end of the buffer structure, the bottom of the base structure is fixedly connected to the top end of the driving structure, the outer wall of the driving structure is movably sleeved with the inner wall of the oil storage structure, and the inner wall of the top of the oil storage structure is slidably connected to the outer wall of the pressing structure. This bearing manufacturing and pressing device with a fixed structure and its usage method, through the coordinated use of the buffer structure, driving structure, and pressing structure, avoids the easy displacement of the bearing during pressing, allows the inner ring of the bearing to quickly and accurately enter the interior of the outer ring, and prevents the rolling balls from splashing, bringing convenience to the operator.
