Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
as shown in fig. 6, 7 and 8, the utility model provides a discharging mechanism for a feed hopper, which comprises an inner tube 1, wherein the inner tube 1 is rotatably arranged in the feed hopper; the feeding hopper comprises a trough 5 and an outer pipe 2 fixed at the bottom of the trough 5, the inner pipe 1 is rotatably arranged in the outer pipe 2, the outer diameter of the inner pipe 1 is the same as the inner diameter of the outer pipe 2, a feeding chute 6 is arranged at the joint of the outer pipe 2 and the trough 5, and the feeding chute 6 is arc-shaped, namely the feeding chute 6 is formed by cutting along the outer peripheral wall of the outer pipe 2; a part of the outer wall of the inner pipe 1 protrudes out of the feeding groove 6; furthermore, in the process of rotating the inner pipe 1, the spiral discharge groove 11 formed on the inner pipe 1 is utilized, so that the radial length (shown as a in fig. 7) of the part is smaller than the outer diameter of the inner pipe 1, namely, the vertical distance a from the axis of the inner pipe 1 to the notch of the discharge groove 11 is smaller than the outer diameter of the inner pipe 1, and in the process of rotating the discharge groove 11, periodic size change can be formed in the circumferential direction, so that a 'scraping' effect on materials in the circumferential direction is formed, and discharge is promoted;
further, in order to realize the rotation of the inner tube 1, bearing grooves 21 are formed at two ends of the outer tube 2, a bearing 3 is arranged in the bearing grooves, the bearing 3 can be a tapered roller bearing, and is matched with an end cover 4, so that the bearing 3 is well installed, namely, an inner ring of the bearing 3 is embedded on the inner tube 1 (a shaft shoulder needs to be arranged on the inner tube 1), an outer ring of the bearing 3 is installed in the bearing grooves 21, and the end cover 4 is abutted against the outer ring of the bearing 3;
for the rotation of the inner tube 1, the inner tube 1 can be driven by external power, that is, the inner tube 1 is a hollow circular tube, one end of the inner tube is an opening, the other end of the inner tube is a closed end, the open end is used as a discharge port for discharging materials, a driving shaft 13 coaxial with the closed end is fixed on the closed end, a driving wheel 12 coaxial with the driving shaft 13 is fixed on the driving shaft 13, and then the driving wheel 12 is driven to rotate by a driving mechanism such as a motor.
With reference to fig. 1 and 2, the outer circumferential wall of the inner tube 1 is provided with 4 discharge grooves 11 uniformly distributed along the circumferential direction; wherein, the discharge groove 11 is of a spiral structure, the discharge groove 11 is formed by cutting a rectangle which is perpendicular to the axis of the inner tube 1 along a spiral line, namely, the plane of the rectangle is perpendicular to the axis of the inner tube 1, therefore, the discharge groove 11 is provided with a pair of spiral surfaces 111 which extend spirally, the discharge groove 11 is also provided with a pair of end surfaces which are perpendicular to the axis of the inner tube 1, and the included angle of the straight line formed by the two spiral surfaces 111 of the discharge groove 11 on the cross section of the inner tube 1 is 90 degrees (as shown in fig. 4);
referring to fig. 4 and 5, the discharging groove in fig. 4 and 5 is formed by cutting a rectangle which is not perpendicular to the axis of the inner tube 1 along a spiral line, and it can be seen that two end surfaces formed at two ends of the discharging groove are not perpendicular to the axis of the inner tube 1, and the included angle of the straight line formed by the two spiral surfaces on the cross section of the inner tube 1 is accurate to an integer of 120 degrees, i.e. the included angle of the notch formed in fig. 5 is larger than that of the notch in fig. 3, because the rotating of the inner tube 1 generates the 'scraping' effect on the material, the larger the included angle of the formed notch is, the more the inclination is, and the more the notch tends to be 'gentle', and the scraping effect of the vertical surface is better when compared with an inclined surface and a vertical surface, so the scraping effect of the discharging groove in fig. 3 is better than that of the discharging groove in fig.
Further, the number of turns of the spiral line corresponding to the discharge groove 11 is not more than 1 turn, and the pitch of the spiral line corresponding to the discharge groove 11 is larger than the diameter of a base circle (the spiral line is formed by spirally forming the base circle) corresponding to the spiral line, and the diameter of the base circle is the same as the outer diameter of the inner pipe 1; this arrangement of the helix of the discharge chute 11 makes the helical chute axially longer, as follows:
referring to fig. 2, the ratio of the pitch of the spiral line to the diameter of the base circle of the discharge chute 11 is 9: 2, the corresponding number of turns is 0.5, a group of reference values are given specifically, the thread pitch of the spiral line is 180, and the diameter of the base circle is 40;
referring to fig. 8 and 9, the pitch of the spiral line of the discharge chute 11 in fig. 8 is 180, the diameter of the base circle is 40, and the number of turns is 0.5; the pitch of the helix of the discharge chute 11 in fig. 9 is 90, the diameter of the base circle is 40 and the number of turns is 1;
it can be seen that the length of a discharge chute 11 in the feed chute 6 differs, L1> L2, which corresponds to the fact that the length of the discharge chute 11 in the axial direction in fig. 9 becomes shorter, and its displacement in the axial direction is reduced, in a manner of extreme thinking, when L2 becomes smaller and smaller, the discharge chute 11 corresponds to a circular ring, which loses the effect of the axial pushing, so that the length of the discharge chute 11 in the feed chute 6 needs to be set reasonably, and should not be too small, as can be seen in fig. 8, so that the length of L1 is about the length 2/3 of the feed chute 6.
Finally, it should be noted that, since the material is discharged through the inner tube 1, in actual use, the inner tube 1 needs to be disposed obliquely, i.e., as shown in fig. 10, in which the dotted line is a horizontal plane.
In use, the dimensions of the discharge chute 11 are as shown in fig. 8, and it is noted that it is formed by cutting a rectangle perpendicular to the axis of the inner tube 1 along a spiral line, and then, as shown in fig. 6, the inner tube 1 is installed into the outer tube 2, and the rotation direction is as shown by the arrow in fig. 7, and during the actual operation, the inner tube 1 needs to be tilted for discharging;
in the using process, it should be noted that the rotating speed of the inner pipe 1 is not too fast, if the rotating speed of the inner pipe 1 is too high, the material may not fall in time, and the material discharge groove 11 of the inner pipe 1 already passes through the material inlet groove 6, so that in the actual using process, the rotating speed is relatively low, and the material discharge groove can be specifically arranged in the actual using process, and the application is not limited in detail.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
