The utility model has the beneficial effects that the charging barrel can be erected on the supporting seat, and the supporting seat is formed by enclosing the hollow pipes, so that the cooling liquid channel surrounds the periphery of the charging barrel, the cooling liquid outlet is just aligned with the outer wall surface of the charging barrel, and cooling liquid flowing out of the cooling liquid outlet can be just poured on the outer wall of the charging barrel; therefore, the charging barrel is cooled during ultrasonic crushing and dispersing operation.

The utility model belongs to the field of pesticide spraying device, concretely is a kind of lotus root planting organic fertilizer pesticide spraying device, the bottom of spraying device is provided with locating plate, the upper portion of locating plate is inserted with antiskid rod, the bottom fixedly connected with locating plate has connecting column, the bottom fixedly connected with connecting column has bearing plate, when the spraying device of connecting column upper portion is moved by bearing plate, the pesticide spraying pipe of spraying device side portion can carry out pesticide application to lotus root pond, and the bottom of bearing plate is in contact with lotus root pond silt ground area, avoid spraying device in the process of moving to sink into silt ground, to reduce work intensity, while the end of bearing plate is provided with pry plate, so that in the process of bearing plate movement, when the protruding soil layer is encountered in moving path, it can also pass smoothly, the stop block can prevent steering rod from continuing to rotate when steering rod is in vertical state, so that the steering rod can be kept in place, and multiple antiskid rods can form a fence to avoid the spraying device from falling during movement.

The utility model discloses a novel concentrated liquid back-spraying pressure stabilizing system, which relates to the technical field of concentrated liquid back-spraying and comprises a landfill leachate tank, and the liquid outlet end of the landfill leachate tank is connected with the liquid inlet ends of a first concentrated liquid back-spraying pump and a second concentrated liquid back-spraying pump through pipelines. The liquid outlet end of the first concentrated liquid back-spraying pump and the liquid outlet end of the second concentrated liquid back-spraying pump are connected with a back-spraying middle pool through a main pipeline; when the device is used, leachate in the landfill leachate pool is pumped out through the first concentrated liquid back-spraying pump or the second concentrated liquid back-spraying pump and conveyed into the back-spraying middle pool through the main pipeline, the back-spraying middle pool can be used as a transfer station, and the fall between the first back-spraying stabilized pressure pump and the first spray gun assembly and the fall between the second back-spraying stabilized pressure pump and the second spray gun assembly are small. The conditions that the pipeline is too long and the resistance is large are avoided, the loss of outlet pressure heads of the first back-spraying pressure-stabilizing pump and the second back-spraying pressure-stabilizing pump is reduced, the back-spraying pressure of concentrated liquid is stable, the gas-liquid pressure ratio of the spray gun is guaranteed, and therefore the atomization effect of the spray gun is improved.

The utility model discloses a leaf lycium barbarum disease and pest prevention spraying device, which belongs to the technical field of agricultural appliances and comprises a main body, a pesticide spraying mechanism is fixed at the top end of the main body, one side of the pesticide spraying mechanism is connected with a pesticide liquid tank, and the pesticide spraying mechanism comprises a lower spraying pipe. The two sides of the bottom end of the lower spraying pipe communicate with lower spraying heads, a booster pump is fixed to the bottom end of the lower spraying pipe, the top end of the lower spraying pipe is sleeved with a telescopic pipe, and the bottom end of the telescopic pipe is sleeved with a sealing plug. According to the spraying device, a spraying structure formed by combining the lower spraying pipe and the upper spraying pipe is arranged at the top end of the frame, lower spraying heads communicated with the two sides of the lower spraying pipe can be used for spraying lower stem positions of passing planting fields on the two sides, and upper spraying heads can be used for spraying upper positions; in cooperation with an electric telescopic rod, telescopic adjustment can be achieved so as to adapt to the heights of leaf-use wolfberries with different growth vigor, and therefore the coverage degree of sprayed pesticide is ensured while manpower is saved, and spraying dead angles are avoided.

The utility model provides a spraying device for a waterproof test of textiles, and belongs to the technical field of machinery. The problem of poor stability in the prior art is solved. The spraying device for the waterproof test of the textiles comprises a rack and further comprises a driving part, a guide rail, a sliding block and a spraying assembly, the guide rail is vertically arranged on the rack, the spraying assembly is connected to the guide rail, the driving part is fixedly connected to the rack and connected with the spraying assembly, a height identification assembly is arranged between the spraying assembly and the rack, and the height identification assembly is connected with the sliding block. The driving piece can drive the spraying assembly to horizontally move up and down along the guide rail, and the height position of the spraying assembly can be visually checked through the height identification assembly after the spraying assembly moves. The spraying device for the waterproof test of the textiles is high in stability.

The invention relates to the technical field of mechanical property testing, and provides a preparation method of flexible speckles for biological soft tissues, a composite test body and application of the composite test body. The flexible speckle is obtained by spraying a bi-component polyurethane coating on the surface of a biological soft tissue and then curing the bi-component polyurethane coating. The prepared flexible speckle has excellent elasticity and adhesive force, can cooperatively deform along with tissues under the condition of relatively large tensile strain without generating obvious cracking, peeling or relative slippage, and can meet the requirements of a biological soft tissue large deformation mechanical test; meanwhile, the preparation method provided by the invention is simple to operate, does not need complex pretreatment such as primer precoating and polishing, and is good in repeatability and wide in application range.
