A block validity verification method for a blockchain sharding system, the blockchain sharding system comprising a plurality of shards, each shard generating a new block based on transaction requirements and reaching a consensus within the shard to generate verification evidence of the block, the method comprising the following steps: randomly selecting 2 times a preset number of shards other than the shard where the block is located in the blockchain sharding system to form a verification shard set; using each shard in the verification shard set to verify the block, and broadcasting the verification result to other shards; and determining that the block and the shard where it is located are successfully verified when at least half of the shards in the verification shard set verify that the block is valid.

The invention relates to an auxiliary fragmentation device for endoscopic examination of the digestive department. The auxiliary fragmentation device comprises an endoscope tube, the endoscope tube is provided with a forceps channel, a titanium clamp is arranged in the forceps channel, a camera module is arranged at the end, close to a port of the forceps channel, of the endoscope tube, and a fragmentation channel is arranged in the endoscope tube and close to the forceps channel; the fragmentation assembly is arranged in the fragmentation channel, the fragmentation assembly comprises a bearing rod, a connecting seat, a mounting frame and fragmentation blades, the bearing rod is arranged in the fragmentation channel, the connecting seat is telescopically arranged at the end of the bearing rod, the mounting frame is rotationally arranged on the end face of the connecting seat, and the fragmentation blades are arranged on the mounting frame. The mounting frame is provided with a plurality of driving blocks, and the tail ends of the crushing blades are mounted on the driving blocks. According to the invention, large blood clots can be effectively fragmented into small fragments, which are convenient for a titanium clamp to clamp and remove, so that the efficiency and accuracy of endoscopic examination are improved.

The geological sample fragmentation device comprises a fragmentation box supported on the ground through supporting legs, a fragmentation assembly is arranged in the fragmentation box and comprises a hollow cylinder, a beating roller and an impact plate, the hollow cylinder is rotationally connected to the lower surface of the top of the fragmentation box, a plurality of receding grooves are formed in the inner wall of the hollow cylinder, and the beating roller is arranged in the receding grooves. The beating roller is rotationally connected to the inner walls of the crushing box and the hollow cylinder through a first transmission shaft, the outer wall of the beating roller is fixedly connected with a plurality of beating plates arranged in the radial direction, the impact plate is fixedly connected to the inner wall of the crushing box, and the inner wall, located at the bottoms of the hollow cylinder and the beating roller, of the crushing box is fixedly connected with a fixing frame; a driving assembly used for driving the hollow cylinder and the beating roller to rotate is arranged in the fixing frame. Through the arrangement of the hollow cylinder and the beating roller, when a geological sample enters the space between the hollow cylinder and the beating roller, the beating roller drives the beating plate to rotate to beat the geological sample to realize crushing treatment, and the defect that the large geological sample cannot be treated is avoided.

The utility model relates to dry sludge fragmentation technical field especially is a kind of new fragmentation device for the pretreatment of metal dry sludge, including horizontal fragmentation cylinder, and one motor set is equipped in horizontal fragmentation cylinder outer end side portion, and motor set driving shaft extends to inside by penetrating horizontal fragmentation cylinder, and one transverse placement rotating rod is equipped in horizontal fragmentation cylinder axis, and rotating rod one end is connected with horizontal fragmentation cylinder inner wall by sleeve setting mode, and rotating rod one end is connected with motor set driving shaft, and motor set driving shaft drives rotating rod axial rotation;Rotating rod surface layer includes push plate and cutter group, and cutter group includes multiple arrayed main cutters, and multiple vice cutters are equipped in array on main cutter;While push plate end portion is equipped with the scraper that is contacted with horizontal fragmentation cylinder inner wall;The technical scheme is that the vice cutter that is equipped is additionally added on the basis of existing main cutter, so as to increase cutter and metal dry sludge cutting surface and cutting angle in cylinder body, can optimize its fragmentation effect.
