fishtail propeller

ActiveCN117104475Bgo fasteasy to operateWater flowStructural engineering
This invention relates to a fishtail-type propeller propeller, comprising a base for fixing to a hull, a rotating shaft vertically supported on the base and rotatable relative to the base, and a vertically mounted propeller plate. A laterally extending connecting rod is fixed to the rotating shaft. The invention is characterized by: a limiting seat fixed to the connecting rod, the limiting seat having a vertically extending shaft hole in which a pin is installed; the propeller plate being fixed to the pin and located below the limiting seat; a limiting member also being provided on the pin; and an arc-shaped movable space centered on the pin and a limiting part inserted into the arc-shaped movable space between the limiting member and the limiting seat. The propeller plate rotates relative to the limiting seat within the range defined by the arc-shaped movable space via the pin. This invention allows the propulsion of the hull to come from the combined force of the flexible connection between the water flow and the propeller plate and the rigid connection between the rotating shaft and the propeller plate, which, under the same conditions, helps to increase the forward speed of the hull and is easy to operate.

Winnowing machine for matcha processing

ActiveCN121972404AHigh precisionImprove efficiencyGas current separationPre-extraction tea treatmentReciprocating motionDrive shaft
The invention relates to the technical field of tea processing equipment, and discloses a winnowing machine for matcha processing, which comprises a motor, a transmission shaft, a belt pulley group, a driving shaft and a support, the motor drives the transmission shaft and the driving shaft to rotate, the driving shaft is connected with a cam, and a grading groove is arranged in the cam to drive a cross rod to reciprocate. The cross rod drives a material homogenizing plate with carding teeth to swing and scatter raw materials, an airflow guide structure comprising a contraction section, a throat section and an expansion section is arranged below the material homogenizing plate, and a vortex groove is formed in the inner wall of the expansion section to assist airflow separation. An intercepting mechanism composed of a connecting rod, a spring and elastic hook teeth is arranged in the winnowing cavity. The problem of caking of raw materials is solved through mechanical vibration homogenization, the sorting precision is improved through Venturi vortex airflow, flat yellow pieces are effectively removed in cooperation with a self-weight type mechanical intercepting mechanism, and the matcha winnowing efficiency and the finished product purity are remarkably improved.
