The sliding support wheel portion 706 comprises a limiting plate 706a arranged on the inner top surface of the second heat-preservation square barrel 3, an upper limiting port 706b and a lower limiting port 706c arranged on the limiting plate 706a, a combined cylinder 706d arranged on the upper limiting port 706b and provided with a square exposed end, a threaded cylinder 706e arranged on the lower limiting port 706c and provided with an exposed threaded section, a connecting plate 706f arranged on the inner side end surface of the combined cylinder 706d and the threaded cylinder 706e, and a supporting roller 706g arranged at the lower end of the side surface of the connecting plate 706f and used for rolling on the lower surface of the object carrying plate 701. The sliding support wheel portion 706 further comprises a square cover 706h arranged at the square exposed end, an insertion column 706k arranged on the inner side surface of the square cover 706h, insertion grooves 706m arranged on the upper side and the lower side of the upper limit opening 706b in a linear arrangement mode, a fastening nut 706p arranged on the exposed thread section, elastic clamping strips 706r arranged on the upper side and the lower side of the lower limit opening 706c, and an elastic rope 706t arranged between the square cover 706h and the square exposed end.
In this embodiment, the sliding support wheel portion 706 is used for adjusting the tilt angle of the object plate 701, and the adjustment method is only required to slide toward or away from the mounting shaft 704, and the adjustment method and the use advantage of the sliding support wheel portion 706 are as follows.
First, in an initial state, the fastening nut 706p is tightened against the elastic clamping strip 706r, the insertion post 706k is inserted into the insertion groove 706m, and the insertion state is maintained by the elastic retraction force of the elastic cord 706t, so that the assembly cylinder 706d, the threaded cylinder 706e, the connection plate 706f, and the support roller 706g cannot move as a whole, and the carrier plate 701 is fixed at a certain inclination angle.
Then, it is found that the scraped fodder on the carrying plate 701 falls back to the conveyer belt 11 without being sufficiently heated and dried, and at this time, the inclination angle of the carrying plate 701 is decreased to make the scraped fodder slowly fall off, so as to increase the heating time of the electric heating wire heater 6, and of course, all the scraped fodder on the carrying plate 701 can be properly turned over in the process, so that the scraped fodder has a basic heating effect on the carrying plate 701 and a final supplementary heating effect when the scraped fodder falls off the carrying plate 701.
In this process, the tightening nut 706p is loosened and held, the square cap 706h and the insertion post 706k are pulled out, the carrier plate 701 is lifted upward by pulling the tightening nut 706p outward away from the mounting shaft 704 until the insertion post 706k is aligned with the next insertion slot 706m, the insertion post 706k is pulled into the insertion slot 706m by the elastic string 706t, and the tightening nut 706p is tightened again, which is very easy and requires no quick adjustment.
Finally, the sliding adjustment function of the sliding support wheel portion 706 includes stepped adjustment at the square cover 706h and stepless adjustment at the fastening nut 706p, which are matched with each other, so that the dual advantages of small adjustment minimum angle unit amount and high fixing strength after adjustment are achieved, that is, the square cover 706h is idle during stepless adjustment, which is still effective.
Due to the introduction of the sliding support wheel portion 706, the scraped feed on the loading plate 701 can slide off relatively quickly or slowly, so that the scraped feed can be heated sufficiently and appropriately, all the feed can be dried, and the scraped feed cannot be left and discarded.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
