The present invention discloses an impulse-type grouting apparatus with variable voltage variable frequency. The apparatus comprises a barrel. An upper cover is movably assembled on the barrel in a riveting manner, and an inlet pipe is disposed on the upper cover in a through connection manner. A lower end of one side of the barrel is further communicated with a grouting pipe. Two groups of pressure control valves that are used for limiting flow directions and adjusting pressures are further disposed and connected on the upper cover. Both the two groups of pressure control valves are communicated with inside and outside of the barrel. Further, upper ends of the two groups of pressure control valves are respectively communicated with a suction fan and an air blower. A homogeneous structureused for stirring is further disposed and connected inside the barrel. A valve structure that controls a flow speed through rotation is further disposed inside the grouting pipe, and the valve structure drives operation by using a second motor connected on the grouting pipe. According to the impulse-type grouting apparatus, a driving speed of the second motor can be adjusted to control a sizing agent discharging speed, and the sizing agent discharging speed can also be controlled by starting the suction fan or the air blower. Materials can be discharged under cooperation, and an impulse-type grouting effect can be formed as required.

The invention relates to the technical field of a corn seeding machine, specifically to a direct-insertion type duckbill forced seed discharging device for corn. The device is characterized by comprising an installation top plate fixedly connected with a frame of a seeding machine, wherein the installation top plate is provided with a camshaft which is provided with a cam assembly; and a pulling sheet assembly is arranged on the plate surface of the installation top plate at a position corresponding to the cam assembly and is connected with a duckbill assembly via pulling wires. According to the invention, the device can utilize instant dynamic load to shake off soil adhered on the duckbill assembly which is taken out from soil, so the precise corn seeding machine does better in controlling qualified corn plant spacing; a pulling sheet frame is used, so good strength and high precision are obtained; the pulling sheet is used to pull four pulling wires, so structure is simple, and installation is convenient; the direct-insertion type duckbill adaptable to an direct-insertion type rod is adopted, so the problems of soil entering when the duckbill assembly enters the soil and incapability of seed discharging when the duckbill assembly is taken out from the soil; and the device can be timely forced to start according to operation cycles. The device can improve production efficiency of precision corn seeding and mitigate labor intensity of farmers.

The invention relates to the technical field of starch processing equipment, and particularly discloses a lotus root processing slurry dewatering device. The lotus root processing slurry dewatering device comprises a water collecting barrel, wherein a dewatering barrel is rotationally connected into the water collecting barrel; filter holes are formed in the side wall of the dewatering barrel; only a liquid phase runs through the filter holes; a discharge pipe is arranged on the top of the water collecting barrel; a transmission shaft is connected to the bottom of the dewatering barrel; a cavity is formed in the transmission shaft; a vertical rod is arranged inside the cavity; a piston connected with the dewatering barrel in a sliding and sealed manner is arranged on the top of the vertical rod; a curved groove is formed in the side wall of the vertical rod; a guide pin connected with the curved groove in a sliding manner is arranged on the side wall of the cavity; a feeding barrel fixed to the machine frame is arranged above the water collecting barrel; a feeding check valve is arranged at the bottom of the feeding barrel; the feeding check valve is connected with a feed pipe communicated with the dewatering barrel; a push rod is arranged on the top of the piston; the push rod runs through the feed pipe and stretches into the feeding barrel; a plurality of blades are arrangedon the push rod positioned inside the feeding barrel. Through adoption of the technical scheme, the problem that in the prior art, a machine is required to be shut down for taking out starch manuallyin the lotus root slurry dewatering process is solved.

The invention relates to the technical field of steel processing, and discloses a waste steel four-shaft shredding machine which comprises a rack, the middle of the rack is fixedly sleeved with a sieve plate, leaking holes are evenly formed in the sieve plate, and two symmetrical motors I are fixedly connected to the middle of one end of the rack; a motor I is fixedly connected to the base, blade wheels I which are evenly distributed are fixedly connected to an output shaft of the motor I, a hydraulic cavity is formed in the center of each blade wheel I, three movable cavities which are evenly distributed are formed in each blade wheel I, and shredding blades are movably connected into the movable cavities in a sleeved mode. Through the designed blade wheels I, blade wheels II and a sieve plate, after the two blade wheels I conduct preliminary crushing on the waste steel, the crushed waste steel can enter the meshed crushing part of the blade wheels I and the blade wheels II again under the limitation of the sieve plate and the driving of the blade wheels I and the blade wheels II, so that the waste steel is shredded multiple times, and the crushing efficiency is improved. And the shredded waste steel is discharged after reaching the qualified volume.

The invention discloses a filtering device for hot washing liquid in oil production wells, and specifically relates to the field of well washing tools. A large-diameter filter cartridge and an inlet fixing seat are installed inside the inverted head at the inlet end, and a miscellaneous liquid separation cylinder is installed inside the inlet fixing seat and the outlet fixing seat. The side is equipped with a miscellaneous flange, a valve body, and a miscellaneous box. In the present invention, through the conical miscellaneous liquid separation cylinder and the conical helical blade, after the well washing fluid enters the washing liquid filter device, the conical miscellaneous liquid separation cylinder and the conical helical blade form an oblique direction along the tangential direction around the cylinder body. Centrifugal force, and the centrifugal force gradually increases along the outlet direction, so that the sand and gravel of various particle diameters in the well-washing fluid are thrown out of the miscellaneous liquid separation cylinder and separated from the well-washing fluid due to the huge centrifugal force, and the well-washing fluid mixed with small particles of formation sand can also be processed Better filtering effect.
