Embodiment Construction
[0012] In order to further clarify the present scheme, the preferred embodiments of the present invention are described below in conjunction with specific examples. These descriptions are only for further illustrating the advantages of the present invention, rather than limiting the claims of the present invention.
[0013] Such as Figure 1-3 As shown, a suction head of a grain suction machine includes a feed pipe 1, a connector 2, a rotating shaft 3, a bearing seat 4, and a handle 5. The bearing seat 4 is provided with a rotating shaft 3, and the bearing seat 4 and the feed pipe 1 is fixed as a whole through the connecting piece 2, and a handle 5 is provided on the outer surface of the feed pipe 1, which is convenient for moving the suction nozzle of the grain suction machine. An annular groove 6 is provided at the front of the feed pipe 1 for easy connection with a hose. The rear part of the bearing seat 4 is a cylindrical hollow tube 41, and a rotating shaft 3 is arranged...

The invention discloses a suction-injection head of a grain elevator. The suction-injection head comprises a feed pipe, a connector, a rotating shaft, a bearing block and a hand shank, wherein the rotating shaft is arranged on the bearing block; the bearing block and a sleeve connector of the feed pipe are fixed into a whole; the suction-injection head is characterized in that the hand shank is arranged on the outer surface of the feed pipe; an annular groove which is conveniently connected with a hose is arranged at the front part of the feed pipe; a cylindrical hollow tube is arranged at the rear part of the bearing block and the rotating shaft is arranged in the bearing block; balls, a seal ring and an end cover are sequentially arranged between the rotating shaft and the bearing block from front to back; an isolating ring is arranged between adjacent balls; a hollow cone-shaped body is arranged at the front part of the bearing block; and lubricating oil is contained in an internal hollow cavity. The suction-injection head has the beneficial effects of being reasonable in design, compact in structure, firm, practical and good in performance, and has the characteristics of being small in volume, light in weight, convenient to move, high in grain elevating efficiency, low in breakage rate, wide in usage occasion, safe, reliable and long in service life.
Description
Technical field: [0001] The invention specifically relates to a jet suction head of a grain suction machine, which belongs to the technical field of agricultural machinery. Background technique: [0002] The grain suction machine is composed of a motor, a frame, a hose, a shaftless spiral piece and a suction head. Its working principle is that the motor is fixed on the frame, the shaftless spiral piece is installed in the hose, and the front end is connected with the suction head. . When the motor is started, the motor drives the shaftless helical piece to rotate, and the grain at the injection head will rise along the direction of the helix angle of the shaftless helical piece under the action of the shaftless helical piece, and when it reaches the discharge port , due to gravity, automatic grain unloading. The suction head of the existing grain suction machine is inconvenient to insert into the grain pile, and the operation is inconvenient. The bearing lubrication effect...
