Description

A kind of agricultural seeding machine dust catcher

Technical field

The utility model is related to a kind of agricultural equipment, specifically a kind of agricultural seeding machine dust catcher.

Background technology

The suction musical instruments used in a Buddhist or Taoist mass of seeder includes shell, upper end cover, bottom end cover at present, is arranged motor in shell, motor include stator, Rotor and shaft, rotor are fixed on the middle part of shaft, and shaft top and the bottom are fixed on the bearing of upper end cover and bottom end cover by bearing Intracavitary, shaft lower end extend downwardly through the bearing bore and axis hole of bottom end cover, and shaft lower end is fixed with impeller, have air port cover solid The bottom for fixing end cap covers impeller, and air port covers bottom centre and is equipped with air inlet, and air port cover side, which opens up, sets several air outlets, Motor drives fan blade high speed rotation when work, and dust covers adopted air inlet from air port and enters in cover body, then the air outlet quilt from side Discharge, dust can enter the gap between shaft and bottom end cover axis hole above impeller during dust suction, so slowly into Enter to inside bearing bore and motor, to seriously affect the service life of motor.

Utility model content

The purpose of this utility model is to provide a kind of agricultural seeding machine dust catchers, in dust catcher bottom end cover bottom axis hole Periphery is provided with the annular recess coaxial with axis hole, and be equipped at the top of the also fixed dust cap in the lower end of shaft, dust cap with The bulge loop of annular recess cooperation, when motor works, dust cap is rotated synchronously with impeller, due to being equipped between dust cap and bottom end cover Bulge loop and annular recess cooperation so that dust enters inside motor change because of difficulty, while while coordinating dust cap to rotate generate from Mental and physical efforts, the dust that fraction enters are thrown out of in the effect of centrifugal force, greatly reduce dust and enter inside motor, to extend The service life of motor.

For the use following technical scheme for realizing on above-mentioned mesh：

A kind of agricultural seeding machine dust catcher, including shell, upper end cover, bottom end cover, shell is interior to be arranged motor, and motor includes Stator, rotor and shaft, rotor are fixed on the middle part of shaft, and shaft top and the bottom are fixed on upper end cover and bottom end cover by bearing In bearing bore, shaft lower end extends downwardly through the bearing bore and axis hole of bottom end cover, and shaft lower end is fixed with impeller, and feature exists In：The bottom end cover bottom axis hole periphery is provided with the annular recess coaxial with axis hole, is located at impeller in the lower end of shaft Top is also arranged with dust cap, and the bulge loop coordinated with annular recess is equipped at the top of dust cap.

The shaft hole diameter is more than the outer diameter of shaft, and ring-type is additionally provided on the inside of bulge loop at the top of the dust cap Connector sleeve, loop connecting set internal diameter match with spindle outer diameter, and loop connecting set, which is placed in, when dust cap is set in shaft turns In gap between axis and axis hole.

The annular recess has multiple, each annular recess coaxial arrangement, the bulge loop quantity and size at the top of dust cap with Annular recess is corresponding.

It is provided with radiating fin on the outside of the shell.

The outer diameter of the rotor is 12mm-14mm.

The rotor is combined by several magnetic shoes and upper and lower steel bushing, and several magnetic shoes are centered on shaft directly about arrangement Shaft periphery, the upper and lower ends of above-mentioned magnetic shoe are positioned by upper and lower steel bushing.

Annular recess is arranged in bottom end cover stomidium periphery in the utility model, and is arranged in shaft upper end and matches with annular recess The dust cap of conjunction, bulge loop and annular recess cooperation on dust cap play prevent dust directly between shaft and axis hole gap into Enter inside motor, while the rotation of dust cap and shaft synchronous high-speed generates centrifugal force so that enter dustproof cover and bottom end cover it Between dust be excluded, greatly reduce dust and enter possibility inside motor, to extend the working life of motor；In addition originally The rotor of utility model is that magnetic shoe directly wraps up shaft, and centre does not have silicon sheet core, and the purpose designed in this way reduces rotor Outer diameter, the centrifugal force that rotor generates when rotating at high speed is smaller, to reduce the concentricity of rotor and shaft, reduces into product The requirement of machining accuracy reduces difficulty of processing, promotes the cost performance of product to save cost.
