This utility model discloses a wooden door for use with a floor spring, including a front panel (1) and a back panel (2). Two vertical beams (3) are provided between the front panel (1) and the back panel (2). An upper horizontal beam (4) and a lower horizontal beam (5) are provided between the front panel (1) and the back panel (2). Multiple reinforcing beams (6) are provided between the front panel (1) and the back panel (2). A limiting beam (7) is provided on the inner side of one of the vertical beams (3). The upper and lower ends of the limiting beam (7) are fixed to the upper horizontal beam (4) and the lower horizontal beam (5) respectively. The front panel (1) and the back panel (2) are both fixed to the limiting beam (7). A tightly fitted iron square tube (8) is provided between the limiting beam (7) and the vertical beam (3). The bottom of the iron square tube (8) is provided with a connecting shaft (9) that passes through the lower horizontal beam (5). The bottom of the connecting shaft (9) is provided with a socket (10) that mates with the floor spring. This utility model has the advantage of a long service life.

The present invention discloses a screening device for asphalt concrete recycled materials, relates to the technical field of material screening, and solves the problem that asphalt concrete stones stuck on the screening net are pressed through the screening net, causing the mesh holes of the screening net to deform, or causing the asphalt concrete stones to be further stuck on the screening net, resulting in increased difficulty in cleaning the screening net at a later time. The present invention comprises a screening box, a vibrating base is installed at the lower end of the screening box, a plurality of equidistantly distributed screens are installed inside the screening box, and a dredging component is also included for dredging the screen, the dredging component is installed on the lower side of the screen; a driving mechanism is used to drive the dredging component to move; the present invention can push out the asphalt concrete stones blocked in the screen holes of the screen by installing the dredging component and the driving mechanism, so as to achieve the purpose of dredging the screen, and will neither cause the stones to be further stuck in the screen holes of the screen nor cause the screen holes of the screen to deform.

The invention discloses an automatic screw machining treatment device, relates to the technical field of screw machining, and aims to solve the problems that after a screw is machined, the surface needs to be pretreated, so that a covering layer is formed on the surface of the screw, and the effects of smooth surface, rust prevention, corrosion prevention and the like of the screw are achieved. In the market, the steps of acid pickling, coating, polishing and the like are generally needed for screw surface treatment, different devices need to be used for machining treatment in the steps, workers need to treat the screws step by step, the operation efficiency of manual treatment is low, the needed production requirements cannot be met, and the production cost is low. And meanwhile, the acid pickling and coating processes can cause certain harm to the human body. The device comprises a base; and the pickling bin is arranged on the left side of the upper end of the base, a first cleaning bin is arranged on the right side of the pickling bin, and a polishing bin is arranged on the right side of the hot galvanizing bin.

This door / window is provided with vertical frames (13, 14) and a lower frame (12), the vertical frames (13, 14) have wood frame-forming sections (13A, 14A) formed from wood, the lower frame (12) has a metal frame-forming section (12B) formed from a metal such as an aluminum alloy, and the lower frame (12) is connected to a depth surface, which is the inner peripheral side, of the vertical frames (13, 14) at positions where the wood frame-forming sections (13A, 14A) and the metal frame-forming section (12B) correspond to each other. A reinforcement plate (70) having a hardness greater than that of the wood frame-forming sections (13A, 14A) is interposed between the wood frame-forming sections (13A, 14A) and the metal frame-forming section (12B). When the longitudinal profile and the transverse profile are connected, deformation of the longitudinal profile cannot be caused.
