The invention relates to the technical field of curtain wall installation, and discloses a curtain wall installation bracket device for construction engineering, including a mounting frame, the upper and lower ends of the mounting frame are fixedly connected to the limit frame, and the ends of the two limit frames are close to each other Both are provided with clamping parts, and the front of the installation frame is fixedly connected with two protrusions, and the front of the installation frame is provided with a spreading mechanism and a cleaning mechanism. The present invention can take out the collection belt after pulling out the inserting plate, so that Process the dust on the collection belt to avoid too much dust on the collection belt affecting the normal collection effect. At the same time, after the treatment, the collection belt and the insert plate will be retracted to their original positions, and the collection belt will be reset by the counterweight to avoid the collection belt from being incorrect. It will affect the normal dust collection when it is placed on the pad. By using the gas inside the airbag to expand with heat and contract with cold, the airbag will drive the turntable to deflect through the cross bar, and the airflow generated by the deflection and deflection through the turnplate will blow the dust down. , can effectively avoid dust adhesion.

The present application provides an endometrial collection device, which includes: an outer tube, a tube head, a central tube and a collection assembly, the tube head is connected to one end of the outer tube, and the central tube is movably arranged on the In the outer tube, the collection assembly is movably arranged in the pipe head, and the collection assembly includes a slide, a negative pressure hemispherical cover arranged at the front end of the slide, and drives the slide to slide along the inner wall of the pipe head a motor, a pair of linkages pivotally connected to the slide, and a driving block that drives the collection blade at the front end of the linkage to collect endometrial tissue, wherein the drive block is connected to the central tube front end. The endometrial collection device provided by the present application solves the technical problems of poor sampling effect and low practicability of the existing endometrial collection device.

The invention relates to a take-up device, in particular to an oxygen-free copper rod material forming and take-up device, and aims to provides the oxygen-free copper rod material forming and take-updevice which is capable of saving labor, high in efficiency and orderly in take-up. The oxygen-free copper rod material forming and collecting device comprises a support, a rotating shaft, a first gear, a second gear, a rotary table and the like, wherein the rotating shaft is rotationally arranged on the left side of the upper part of the support, the first gear is arranged at the rear end of therotating shaft, and the motor is arranged on the rear side of the upper part of the support. According to the device, the motor is started to rotate so as to drive the first gear to rotate through thesecond gear, and therefore a hollow roller is driven by the rotary table to rotate, so that the hollow roller is used for the take-up of a oxygen-free copper rod material, and the oxygen-free copperrod material on the hollow roller is extruded through a extrusion roller, so that the phenomenon that the unwound oxygen-free copper rod material influences the take-up effect in the take-up process is avoided, and the take-up efficiency can be improved.

The invention provides an environment-friendly rainwater collection device for agricultural planting, which includes a water pump and a water outlet pipe. Four adjusting bolts are installed on the bottom support frame, and the support frame is installed on the top of the bottom support frame. There is a sump, and the sump is a "U"-shaped structure, and a baffle is installed on the left end of the sump, the roller bracket is installed on the top of the sump, and two rollers are installed on the top of the roller bracket, and the traction rope The top is slidingly connected to the outer end surface of the roller, which is conducive to increasing the rainwater collection area on the top of the device, and can collect more rainwater during rainfall, ensuring the water demand of crops in drought periods, and with the collapsible setting of the rainwater collection frame, it is beneficial When the weather is fine, the device is folded and stored to reduce the area occupied by the top of the device, so as to prevent the crops from being blocked and affect the photosynthesis of the crops.
