An undisturbed box type sampler for sediment on water surface layers comprises a mud acquiring bucket, a mud acquiring bucket carrying handle, an expansion bracket, a counterweight and a traction rope. The mud acquiring bucket carrying handle consists of a carrying handle upright column and a carrying handle crossbeam, the carrying handle upright column is fixedly connected with the mud acquiring bucket, small holes are arranged on the carrying handle crossbeam, the expansion bracket comprises an expansion bracket upper plate and an expansion bracket lower plate, expansion bracket upright columns are fixedly connected with the expansion bracket upper plate and the expansion bracket lower plate and fixed onto the expansion bracket lower plate, an expansion bracket strut and the expansion bracket upright columns penetrate through the small holes on the carrying handle crossbeam, a compression spring is sleeved on the expansion bracket strut, the mud acquiring bucket is provided with a square box and two symmetric mud acquiring claws, shaft heads are disposed on two sides of the box, the mud acquiring claws are rotationally connected with the shaft heads, a tension spring is connected between the mud acquiring claws, the mud acquiring claws are connected with suspension plates, the traction rope penetrates through the expansion bracket upper plate to be connected with the carrying handle crossbeam, and the other end of the traction rope penetrates out from a hole on the counterweight. The sampler has the advantages that a sediment-water interface of acquired sediment on a surface layer is clear, layers of the sediment keep well, a sampling process is undisturbed, and the volume of the acquired sediment can be accurately computed.

The invention relates to the field of agricultural machineries, and especially discloses an automatic pomegranate peel cutting platform. The automatic pomegranate peel cutting platform comprises a machine frame, left and right clamping devices, a cutting device, and an upper clamping device; the left and right clamping devices comprise clamping screw rods, a pair of clamping units, and left and right clamping motors; the cutting device comprises a cutting support plate, a rotary cutting motor, a placing plate, a pomegranate base cutting device, and a pomegranate side cutting device; the upper clamping device comprises an upper clamping motor, a first clamping gear, a second clamping gear, an upper clamping base, an upper clamping cylinder, and a clamping claw. The automatic pomegranate peel cutting platform is capable of automatically cutting open the pomegranate fruits from a place cm lower than the flower-fallen sites, as well as automatically cutting the pomegranate peels into six pieces, so that the traditional pomegranate fruit cutting method based on manual cutting is changed. Compared with full artificial pulp obtaining, the work efficiency of the automatic pomegranate peel cutting platform is relatively greatly improved, so that the market demand for large quantities of pomegranate pulp can be satisfied. The automatic pomegranate peel cutting platform is strong in practicability.

The invention relates to a preparation method of a thin film single thermal battery with a central hole. The thin film single thermal battery comprises a die body. The preparation method comprises the steps of firstly, sequentially placing a collector plate with a central hole and an inertia current blocking ring in the die body from bottom to top; secondly, sequentially placing a negative electrode thin film sheet and an electrolyte separator sheet in the current blocking ring; and finally, placing a positive electrode thin film sheet at an upper end of the inertia current blocking ring, and moving the inertia current blocking ring to a hydraulic machine for pressing and formation. The preparation process of the single thermal battery is simplified, the prepared single battery has the advantages of small size, fast activation, high-overload impact resistance, stable electrical property and the like, the production efficiency can be effectively improved, the battery manufacturing cost is reduced, and the single battery has relatively good application prospect.
