Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A sealed and dustproof screw conveyor as shown in the attached figures 1-5: the device comprises a shell 1 and a rotating shaft 2, wherein a feed inlet 14 is formed in the top of the shell 1 close to the front end face 10 of the shell, a discharge outlet 15 is formed in the bottom of the shell 1 close to the rear end face 12 of the shell, and the discharge outlet 15 is arranged in a funnel shape; the rotating blade 21 is arranged on the part of the rotating shaft 2 positioned in the shell 1; the top of the shell 1 is provided with an access hole 16 communicated with the inside of the shell; this facilitates the maintenance of the screw conveyor by an operator through the access opening 16 in the housing 1. The upper cross section of the inside of the shell 1 is square, and the lower cross section of the inside of the shell is an inverted isosceles trapezoid. The rotating shaft 2 is driven to rotate by the rotating motor 3, and the rotating blades 21 convey the material entering the interior of the shell from the feeding hole 14 to the discharging hole 15.

The rotating shaft 2 is arranged in the housing 1 along the length direction; a through hole 11 is formed in the front end face 10 of the shell 1, the through hole 11 is obliquely gathered towards the interior of the shell 1, and the front end face 10 of the shell 1 at the through hole 11 is convexly thickened, so that when the rotating shaft 2 rotates in the through hole, the supporting force of the side wall of the front end face 10 at the through hole 11 on the conical bearing 4 is larger, and the conical bearing 4 and the rotating shaft 2 are favorably maintained to be stable; the front end of the rotating shaft 2 passes through the through hole 11 and is connected with a rotating motor 3 arranged outside the shell 1; the rotating motor 3 is arranged on the base 9, and the base 9 is fixedly arranged with the outer front end surface 10 of the shell 1 through a flange 91; the one end that conical bearing 4 is located the casing 1 outside is passed through the bolt fastening on ring flange 91, and the installation of the rotating electrical machines 3 that set up like this is firm, avoids shaking when rotating electrical machines 3 rotate and arouses that rotation axis 2 takes place to rotate in casing 1 inside and beats to avoid influencing the normal transportation of helical blade 21 to the material. A conical bearing 4 is arranged between the rotating shaft 2 and the through hole 11, the conical bearing 4 can bear the radial load force from the rotating shaft 2, and the conical bearing 4 arranged in the way can prevent dust from entering the conical bearing 4 to the maximum extent; a sealing cover 5 with a middle through hole is fixedly arranged on the front end face inside the shell 1, a rubber sleeve 6 is fixedly arranged at the middle through hole of the sealing cover 5 through a bolt, and the rubber sleeve 6 extends into the sealing cover 5, so that the rubber sleeve 6 is not easily infected with impurities in materials; rotation axis 2 passes the middle through-hole of sealed lid 5 to through the sealed setting of rubber sleeve 6, 6 hoops of rubber sleeve are on rotation axis 2, thereby can avoid 1 inside material of casing and flying dust card to go into and cause the bearing to block up in conical bearing 4, and then can keep rotation axis 2's normal rotation, extension screw conveyer's life.

A fixing cavity 13 protruding outwards is formed in the rear end face 12 of the shell 1, the fixing cavity 13 is coaxially arranged with the rotating shaft 2, and the tail end of the rotating shaft 2 is rotatably arranged in the fixing cavity 13; a rotary bearing 7 is arranged in the fixed cavity 13, and the tail end of the rotary shaft 2 is sleeved in the rotary bearing 7; by disposing the rear end of the rotary shaft 2 inside the housing 1, interference of the outside with the rotation of the rotary shaft 2 can be avoided. Still including toper rubber sleeve 8, 8 covers of toper rubber sleeve are established and are hugged closely the setting on rotation axis 2, and toper rubber sleeve 8 passes through the fixed setting of bolt cover on 1 inside rear end face 12 of casing, and toper rubber sleeve 8 can block in 1 inside shot of casing enters into swivel bearing 7, causes swivel bearing 7 to block up and influences the rotation of rotation axis 2.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
