The invention belongs to the technical field of cement production, particularly relates to a fluctuating roller type feeding machine, and aims to solve the problem that an existing fluctuating roller type feeding machine cannot simultaneously guarantee the screening requirement of a feeding end and the conveying requirement of a discharging end. The device comprises a conveying mechanism, and the conveying mechanism comprises a plurality of fluctuation rollers arranged in the conveying direction; the maximum excircle diameter of the fluctuation roller is gradually reduced from the feeding end to the discharging end; the rotating speeds of the fluctuation rollers are the same. The fluctuating roller at the feeding end of the fluctuating roller type feeder is large in diameter, high in linear speed and strong in fluctuating effect, materials can be quickly pushed to roll and screen, layering of the materials with different particle sizes is efficiently achieved, and the feeding and screening requirements are met; the fluctuation roller at the discharging end is small in diameter, low in linear speed and weak in fluctuation effect, disordered disturbance caused by too high movement speed and violent fluctuation of materials can be avoided, and then the stable conveying flow direction of the materials is prevented from being damaged, so that smooth discharging can be guaranteed, meanwhile, secondary mixing of fine materials is reduced, and the screening precision is improved.

The utility model discloses an energy-saving fluid motor resistant to high pressure and pressure pulsation, and relates to the technical field of hydraulic motors, the energy-saving fluid motor comprises a motor body, cup-shaped blades, an output wheel shaft and a shock wave recoverer; the periphery of the output wheel shaft is connected with a plurality of cup-shaped blades; the motor body is further provided with an oil inlet channel, an oil outlet channel and a shock wave channel. The large pulse flows through a shock wave recoverer at the bottom of the shock wave channel, is boosted and stabilized and then enters a flow-aiding channel and a braking channel on the two sides; a flow-aiding control valve is connected in the flow-aiding channel, and a brake control valve is connected in the brake channel; when the flow-aiding control valve is opened, the cup-shaped blade drives the output wheel shaft to rotate under the impact of incoming flow in the oil inlet channel and the flow-aiding channel; when the brake control valve is opened, the brake channel conveys the pulsating flow subjected to pressure boosting and pressure stabilizing into the cup-shaped blades, rotation of the cup-shaped blades is hindered, and the output wheel shaft can achieve flexible semi-brake under the action of opposite torque.

The utility model relates to a kind of seeding device components, especially a secondary seed guiding mechanism of high-speed seeding point seeding device suitable for cotton, corn or sunflower large-grain seeds, containing annular clamping plate (11) of both sides and the guide plate (12) between annular clamping plate (11), guide plate (12) is the plate that is radially erected between guide plate (12) cross section presents "scoop", and, the guide plate (12) will annular clamping plate (11) between be separated into several curved and be equipped with import and export radial passage.For the utility model can greatly increase the diameter of seeding point seeding cylinder, set more point seeding nozzle on point seeding cylinder, in the same case of seeding speed, can substantially reduce the linear velocity of seed taking tray, prolong seed taking time, ensure the reliability of seed taking, to further improve seeding speed and operation quality.

The utility model relates to a medical cutter and a medical grinding device. The medical cutter comprises a supporting handle body, an outer cutter tube, an inner cutter bar and a sealing sleeve. The near end of the outer knife tube is connected with the supporting handle body. The inner cutter bar is rotatably arranged in the outer cutter tube in a penetrating mode and further rotatably arranged in the supporting handle body in a penetrating mode. The sealing sleeve is arranged in the outer cutter tube, the inner cutter bar penetrates through the sealing sleeve, and the outer wall of the inner cutter bar and the inner wall of the sealing sleeve are arranged at intervals. By means of the arrangement, the sealing sleeve plays a role in blocking liquid, has good sealing performance and can prevent the liquid from flowing into the supporting handle body along the interval space between the inner cutter bar and the outer cutter tube. Besides, under the condition that the sealing sleeve is arranged, the outer diameter of the inner cutter bar can be reduced as much as possible, the linear speed of the inner cutter bar during high-speed rotation is relatively reduced, and therefore heating during dynamic sealing can be reduced, abrasion is reduced, and the service life can be prolonged.
