Specific embodiment
Referring to attached drawing, the present invention will be further described.
Present embodiment discloses a kind of feed devices, as shown in Fig. 2, including reduction gearbox 1, being rotationally connected with reduction gearbox 1
Screw rod 2 and the barrel 3 that is fixed on reduction gearbox 1.And screw rod 2 is located in barrel 3, the one end of barrel 3 upward, which is provided with, to be used for
The feed inlet 4 of charging.In normal work, after 1 external motor of reduction gearbox, motor work makes screw rod by reduction gearbox 1
2 rotations, raw material in feed inlet 4 after entering, to movement at the position far from reduction gearbox 1 under the rotation of screw rod 2.
As shown in Figure 2 and Figure 3, it is provided with oil sealing 5 on reduction gearbox 1, the placement ring positioned at 5 outside of oil sealing is provided on reduction gearbox 1
Slot 6, and oil sealing 5 is located within the inner sidewall for placing annular groove 6.Part is additionally provided in reduction gearbox 1 to be located in placement annular groove 6 and cover
Firmly the protection cap 7 of oil sealing 5, screw rod 2 are passed through from the centre of protection cap 7.
As shown in figure 3, be rotatably connected to rotation axis 8 in reduction gearbox 1, open that there are two outer limiting slot 9, screw rods 2 in rotation axis 8
It is inserted into rotation axis 8 and is provided with the interior limiting slot 10 corresponding to outer limiting slot 9, is set in outer limiting slot 9 and interior limiting slot 10
The same flat key 11 is equipped with to realize the key connection of rotation axis 8 Yu screw rod 2.It is provided in protection cap 7 corresponding to interior limiting slot 10
Recessed groove 12, a part of flat key 11 are inserted into recessed groove 12.When screw rod 2 rotates, protection cap 7 is rotated with it.
As shown in figs. 3 and 5, protection cap 7 is equipped with sidewall end 13, and the inner wall of the sidewall end 13 is interior with placement annular groove 6
The contact of annular groove wall, plays the role of stable protection cap 7, convenient for the stable rotation of protection cap 7.The bore diameter of outer ring for placing annular groove 6 is big
In the maximum gauge of protection cap 7, after protection cap 7 is mounted at placement annular groove 6, the outside of protection cap 7 and the outer ring for placing annular groove 6
There is gap between slot.Fixed on the outer wall of sidewall end 13 there are two the extension blocks 14 being equally spaced along 7 circumference array of protection cap, i.e.,
Two extension blocks 14 are symmetrical arranged in 180 degree.Two extension blocks 14 are respectively positioned in placing groove.When protection cap 7 rotates, two are prolonged
Block 14 is stretched to rotate with it.
As shown in figure 3, being provided with connection on reduction gearbox 1 places annular groove 6 and the extraneous road Chu Fen 15, and the road Chu Fen 15 is located at
The lower half of reduction gearbox 1.
Specific operating condition is as follows:
After reduction gearbox 1 connects motor, motor work, the rotation axis 8 in reduction gearbox 1 is rotated, and the flat key 11 in rotation axis 8 is with turning
Moving axis 8 rotates, since a part of flat key 11 is inserted into the interior limiting slot 10 of screw rod 2, to realize the rotation of screw rod 2, together
A part of Shi Pingjian 11 is inserted into recessed groove 12, and while screw rod 2 rotates, protection cap 7 and extension block 14 rotate together.
Since screw rod 2 is during feeding, have some granule dusts always to there is the place in gap mobile, these granule dusts by
To protection cap 7 in the gap being moved to after blocking between 13 outer end wall of external groove sidevall and sidewall end for placing annular groove 6, and because spiral shell
While rotation, extension block 14 is also rotating bar 2, and the granule dust placed in annular groove 6 is pushed to the road Chu Fen by extension block 14
15 go out, these granule dusts finally go out to be discharged from the road Chu Fen 15, play the role of protecting oil sealing 5.It should be noted that by
It is rotated synchronously in protection cap 7 and screw rod 2, protection cap 7 is close compared with the part that screw rod 2 contacts all over the body can be done, and avoids powder
Dirt passes through between protection cap 7 and screw rod 2.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to restrict the invention, all in design structure of the invention
Within think of, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
