The invention belongs to the field of household kitchen appliance manufacturing, in particular to a flow resisting hood for a food processor, which comprises a flow resisting hood body, and the connecting end of the flow resisting hood body and a lower cover of a handpiece of the food processor is an open end. The flow resisting hood is characterized in that the horizontal cross-section on the lower end of the side wall of the flow resisting hood body has a non-circular structure; the horizontal cross-section on the lower end of the flow resisting hood body is oval; the horizontal cross-section on the lower end of the flow resisting hood body is polygonal; the connection between sides of the polygonal side wall on the lower end of the flow resisting hood body is arc transitional connection; the upper end of the side wall of the flow resisting hood body, connected with the lower cover of the handpiece of the food processor, is circular; and the upper end of the side wall of the flow resisting hood body, connected with the lower cover of the handpiece of the food processor, is polygonal, and the number of sides of the upper end corresponds to the number of sides of the lower end of the flow resisting hood. The flow resisting hood adopting the structure has good pulping effect.

The invention discloses a water cooling multi-connection type unit water flow control structure. The water cooling multi-connection type unit water flow control structure comprises an outer connectionrotation shaft, a shell, a water inlet, a bolt, an observation window, a water outlet, a stop block, a buffer chamber, a rotation shaft, a mounting fixing ring, an inner shell, a seal strip, a waterflow buffer mechanism, a filter net, a steel ring, a triangular spiral fan, a thread, a second water outlet and a fixing block; the water flow buffer mechanism, the triangular spiral fan, a flow limiting damping structure and a height limiting structure are arranged, the water flow can be reduced secondarily, the passing water flow is reduced, the water flow acceleration is carried out through external connection of a small motor, the water circulation flow can be directly improved, the flow limiting damping structure and an intercepting plate are arranged, the water flow inertia and the spring elastic characteristics are used for automatic flow limiting, electric control is not needed, the energy cost is increased, the height limiting structure is arranged, a movable plate is supported, the pressure borne by the spring is reduced, and the service life of the spring is directly prolonged.

The invention discloses a farmland non-point pollution stepped undercurrent dam ecological purification ditch system. The system has a trapezoidal ditch section; the ditch wall and ditch bottom on two sides of the ditch are provided with seepage-proofing building blocks; hexagonal hole structures are formed in the middle of the building blocks, and plants are planted on the hexagonal hole structures; the periphery of the building blocks are laid with pebbles and fibers; undercurrent dams are arranged in the ditch body in a distance of 10-20m at an interval; an intercepting plate is arranged at a part which is 1m away from the upstream of the undercurrent dam; small holes are formed on the lower part of the intercepting plate; the upstream face of the dam body of the undercurrent dam is provided with a fine grid filtering net; the lower part of the dam body is provided with a filling layer which takes gravel and ceramsite as fillings; the filler particles are gradually thinned along the water flow direction; the upper part of the dam body is provided with a clay layer; and plants are planted on the clay layer. The problem that large land is occupied in ecological engineering is solved, the system has the characteristics of high treatment efficiency, wide application range, good visual effect and the like, the water body is subjected to full-face purification at the normal water level, and the normal drainage and flood discharge functions during large-rainfall period are not influenced.

The invention relates to a high-stability pumping device capable of enhancing a water flow. The pumping device comprises a bottom plate and a connecting pipe mouth. Rotating shafts are inlaid in the two ends of the lower end of the bottom plate; and support rods are connected to the lower ends of the rotating shafts. An air cushion is arranged at the lower end inside the bottom plate. Fixed clamping plates are installed at the two sides of the upper end of the bottom plate; and support columns are installed at the upper ends inside the fixed clamping plates. First springs are fixed at the upper end of the bottom plate; and a top plate is embedded in the upper ends of the first springs. The high-stability pumping device has the following beneficial effects: the bottom plate is supported bythe support columns to prevent the direct contact between the bottom of the bottom plate and a river bed, so that a phenomenon that the inside of the pumping device is blocked because the sediments onthe river bed are pumped by a first water pump and a second water pump that are arranged inside the pumping device and thus the water flow of the device is reduced is avoided. Meanwhile, the bottom plate and the river bed are arranged at a certain distance and thus the first water pump and the second water pump are in contact with the water source fully, so that the water flow of the device is increased.
