The invention belongs to the technical field of precision seeding of agricultural machinery, and particularly relates to a plate-type hole tray seeding device for precision seeding of a whole hole tray and seeding method thereof. The plate-type hole tray seeding device comprises a hole tray conveying belt, a seeding support arranged above the hole tray conveying belt, a seeder hinged with the seeding support, and a vibrator arranged beneath the seeder, wherein the seeder comprises a seed adsorbing plate and a negative-pressure adsorbing device for adsorbing seeds onto the seed adsorbing plate; a fixing plate with seed conveying pipes is arranged above the seeding support; and adsorbing holes on the seed adsorbing plate, the seed conveying pipes on the fixing plate and holes of a hole tray on the hole tray conveying belt are mutually corresponding. Through arrangement of the vibrator, the plate-type hole tray seeding device can adsorb the seeds and sow the seeds under the vibrating action of the vibrator, so that the sowing precision and the sowing quality can be improved.

The invention provides an early-dismantling levelling jacking for a concrete structure formwork. The early-dismantling levelling jacking comprises a threaded rod, a bracket, a movable plate, a round sphere ring, two adjusting nuts and an early-dismantling support; the movable plate is arranged on the bracket; the bracket comprises a support plate and a short cylinder, the interior of the short cylinder is in the shape of a hemispherical bowl surface, one end of the short cylinder is fixedly connected with the bottom surface of the support plate, the spherical radius of the round sphere ring surface in the round sphere ring is the same as that of the hemispherical bowl surface in the short cylinder, the size of the round sphere ring is matched with that of the short cylinder, and the short cylinder and the round sphere ring are fixedly arranged up and down; the top of the threaded rod is fixedly connected with a round sphere, the sphere radius of the round sphere is matched with the spherical radius of the hemispherical bowl surface in the short cylinder, and the threaded rod is in spherical hinged connection with the bracket through the limit of the round sphere ring. According to the early-dismantling levelling jacking for the concrete structure formwork, jacking levelling of a formwork supporting system can be achieved, and the construction quality of the concrete structure surface at the jacking position can be guaranteed.

The invention discloses a motor with high stability. The motor comprises a case, and an end cover component connected and matched with the case; the end cover component comprises an end cover connected with the shell, at least three damping blocks arranged on the inner wall of the end cover, and a through hole through which a rotor penetrates from the end cover; a first flange is arranged on the end cover, a second flange is arranged on the case, and a socket recess for the insertion of the second flange is arranged on the first flange. A rotating shaft can be protected by arranging the end cover component, three damping blocks are arranged on the end cover to reinforce the weight of the whole end cover, the vibration frequency of the whole motor is improved in the work process of the motor, so that the vibration frequency of the whole motor is small, and the stability is high.

The invention discloses a disinfection device for oral treatment, which belongs to the technical field of medical devices. One side of a liquid storage tank is fixedly connected with a nozzle housing, and one end of the nozzle housing is provided with a rotating tube, and one end of the rotating tube is connected with a nozzle through a screw thread. , the other end of the nozzle is provided with a nozzle, the nozzle is provided with a liquid guide hole, the inner wall of the liquid guide hole is provided with an internal thread, the surface of the rotating tube is provided with an external thread that matches the internal thread of the liquid guide hole, and the surface of the liquid guide hole is provided with an external thread that matches the internal thread of the liquid guide hole The inner wall is threadedly connected with the surface of the rotating tube. The structure of the liquid storage tank and the spray tube provided by the oral treatment and disinfection equipment is convenient for the user to hold and disinfect the patient's oral cavity, which improves the convenience of use of the disinfection equipment, and the set spray tube is convenient. Disassembly, cleaning and disinfection, and the set filter plate can ensure the smooth discharge of internal air while filtering, avoiding the generation of water film, making the addition of disinfectant more smooth, and improving the comfort of use of the disinfection equipment.

The invention relates to an energy-saving type sowing device used for plug seedling, and belongs to the field of agricultural machine and greenhouse machinery. The device comprises a seed case component, a seed separating component, a fan component, a silicone pipe I, and a silicone pipe II. The one end of the silicone pipe I is connected with an air hole II on the upper end of a gas-guide component of the seed separating component, and the other end is connected with an air hole of an air inlet of the fan component. The one end of the silicone pipe II is connected with an air hole of an air outlet of the fan component, and the other end is connected with an air hole I of the seed case component. The device has simple structure and low cost, can perform sowing and seed separating by means of sucking seeds by negative pressure of suction of the exhaust fan, guide the air of the air outlet of the fan into the seed case with the silicone pipes, blow the seeds in suspended state directly which is benefit for completing seed suction, save the vibration generator needed by the routine seed case of the seed discharging mechanism, reduce the energy consumption greatly, and improve the work efficiency.

The invention relates to a floating ink cleaning device for an inkjet printing machine, which is mainly used in intermittent inkjet printing machines. At present, there is no floating ink cleaning device for inkjet printing machines that can effectively solve the problem of mist-like ink floating around the nozzle. The invention includes a frame, a conveyor belt, a transmission roller, a nozzle frame and a cross beam. The transmission roller is installed on the frame, the conveyor belt is connected to the transmission roller, the cross beam is fixed on the frame, and the nozzle frame is movably connected to the cross beam. It is characterized by: it also includes a left suction mechanism with an ink filter on the left and used to absorb floating ink around the nozzles of the nozzle rack when the nozzle holder moves to the right, and an ink filter on the right. , and a right air suction mechanism for absorbing floating ink around the nozzles of the nozzle frame when the nozzle frame moves to the left; the left air suction mechanism and the right air suction mechanism are respectively fixed on the left and right sides of the nozzle frame. The invention can effectively improve the printing quality and effectively prevent mist-like ink from suspending around the nozzle.
