The present invention relates to an electro-discharge machining device, which comprises at least a carrier and an electro-discharge machining unit. The carrier is used to carry at least one workpiece to be machined. The electro-discharge machining unit comprises an electrode, a jig and a power supply unit. When the electro-discharge machining unit performs an electro-discharge machining process on a machining target area of the workpiece to be machined along a machining travel direction, a discharge section of the electrode moves relative to the machining target area of the workpiece to be machined. The present invention can improve the machining process, save the overall machining time and save the time required for replacing the electrode.

This utility model discloses a high-precision airtightness testing machine, relating to the field of airtightness testing technology. The utility model includes a testing box with upper and lower cylinders on the top and a testing instrument on the side. A sealing cover is fixedly connected to the bottom of the upper and lower cylinders. A moving mechanism is installed inside the testing box. During airtightness testing, the operator places the product to be tested on a placement platform and clamps it using springs and a clamping arc plate. After starting the motor, the motor drives the threaded rod to rotate, causing the moving sleeve to slide within a stabilizing groove via a stabilizing rod. This, in turn, causes the placement platform to precisely position the product. Subsequently, the upper and lower cylinders move the sealing cover, cooperating with the testing mold to complete the airtightness test. The test results are displayed on the testing instrument. This design achieves automated adjustment and precise positioning of the product, improving testing efficiency and accuracy.

The utility model relates to the technical field of agricultural planting, and disclose an irrigation sprinkler device for agricultural planting, including mobile base, the top of mobile base is installed with rotating mechanism, and the top of rotating mechanism is provided with support column. This irrigation sprinkler device for agricultural planting is provided with motor, screw rod, lifting piece, connecting plate, sprinkler head, receiving plate, pivot and electric push plate, can drive screw rod to rotate and drive lifting piece to lift through starting motor, make the height of sprinkler head adjust, can adjust the spraying range of crops in turn, and starting electric push plate can push receiving plate to rotate on the pivot, make the inclination angle of sprinkler head adjust, make the spraying direction of sprinkler head adjust in turn, make sprinkler head can carry out accurate spraying irrigation to somewhere, reached the effect that the height and angle of sprinkler head were adjusted, improved the practicality of spraying device.

The invention relates to the field of constructional engineering equipment, and discloses a constructional engineering early-dismantling supporting device which comprises a stand column, a lifting mechanism is arranged at the upper end of the stand column, and a support and a top block are installed at the upper end of the stand column through the lifting mechanism. By rotating the threaded sleeve, stabilizing the position of the threaded sleeve through the positioning assembly and stabilizing the position of the stud through the first limiting assembly, the stud can be driven by the stud to move longitudinally, so that the supporting height of the support is adjusted through the lifting mechanism, and the support can adapt to the supporting positions of early-dismantling formworks with different heights; the distance between the top block and the support can be conveniently adjusted through the adjusting assembly so as to adapt to early-dismantling formworks of different thicknesses, the sliding rod is pulled to slide in the sliding groove, the position of the sliding rod is stabilized through the second limiting assembly, and then the distance between the supporting block and the supporting rod can be adjusted through the extending assembly so as to adapt to early-dismantling formworks of different thicknesses. Therefore, the supporting area of the top block can be increased through the supporting block, and the supporting position of the early-dismantling supporting device is more stable.

This invention discloses a liquid manure spraying system suitable for various land conditions, comprising a flexible traction mechanism and a self-balancing application device. The flexible traction mechanism includes a traction motor, a control coil driven by the traction motor, and a flexible traction rope mounted on the control coil. The self-balancing application device includes a chassis, a spraying rod, and a rubber-plug nozzle. The chassis has a rubber tire structure and is connected to the flexible traction rope. During spraying, the flexible traction rope pulls the chassis upwards at an angle. A shock-absorbing structure is installed inside the chassis. The spraying rod includes a fixed rod and a telescopic rod. The fixed rod is fixedly mounted on the chassis and connected to a storage tank via a liquid inlet pipe. The lower end of the telescopic rod cooperates with the fixed rod, and the upper end is equipped with a rubber-plug nozzle. This invention can solve the problems of pipe blockage, uneven spraying, poor spraying effect, and intelligent farmland fertilization in existing equipment, promoting the development of agricultural fertilization towards a more intelligent, convenient, and precise direction.

This invention relates to the field of fire resistance performance testing technology for building samples. The invention discloses a portable coating combustion tester, comprising a water tank, a fan fixed to the top of the inner part of the extraction cylinder, an exhaust pipe fixed to the bottom of the extraction cylinder, a smoke extraction channel fixed to the first end of the first extraction pipe, a first clamping mechanism fixed to the top of the support platform, a bracket fixed to the top of the first extraction pipe, and a second clamping mechanism fixed to the top of the bracket.
