Description

Technical Field

[0001] The invention belongs to the technical field of hoppers, and in particular relates to an automatic hopper drying device. Background Art

[0002] The hopper is a funnel-shaped container installed on the machine for feeding materials.

[0044] Embodiment 3

[0045] Improved on the basis of embodiment 1: Refer to attached Figure 2The second rotating shaft 16 rotates and passes through the base 1 and is fixedly sleeved with a second gear 15.

[0046] The use process and working principle of the technical solution of the present invention are as follows:

[0047] When in use, the hopper body 4 to be dried is placed on the supporting hopper 2, and the air outlet pipe 18 is inserted into the inside of the circular hole 31, and the forward and reverse motor 26 is started, and the output shaft of the forward and reverse motor 26 drives the driving shaft 30 to rotate, and the driving shaft 30 drives the second synchronous wheel 29 to rotate, and the second synchronous wheel 29 drives the synchronous belt 25 to rotate.

[0049] After being discharged from the bottom of the air outlet pipe 18, the hot air enters the interior of the connecting groove 21 through the first circular groove 33, and then is discharged to the bottom of the next supporting hopper 2 to be dried through the second circular groove 34, thereby making full use of the heat to pre-dry the next hopper body 4 to be dried, thereby further improving the work efficiency;

[0050] After drying is completed, the output shaft of the forward and reverse motor 26 reverses. At this time, the output shaft of the forward and reverse motor 26 drives the driving shaft 30 to rotate, and finally drives the hopper cover 5 to move upward and no longer covers the hopper body 4. The driving shaft 30 drives the second rotating shaft 16 to rotate through the third mounting groove 28, and the second rotating shaft 16 drives the second gear 15 to rotate, and the second gear 15 drives the first gear 13 to rotate, and the first gear 13 drives the gear ring 12 to rotate, and the gear ring 12 drives the rotating ring 3 to rotate, and the rotating ring 3 drives the preheated hopper body 4 to move to the bottom of the hopper cover 5, and so on and so forth, completing the function of automatically drying the hopper body 4.
