[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 5 The utility model describes the above technical solution in detail through the following embodiments:

[0026] An onion drying feeder comprises a drying box 1, wherein the drying box 1 is provided with a feed port 11 and a discharge port 12, a feed bin 2 is slidably provided on the top of the drying box 1, a feed pipe 21 is provided at the bottom of the feed bin 2, the bottom end of the feed pipe 21 passes through the feed port 11 and slides to extend into the drying box 1, a detection unit is provided between the feed bin 2 and the drying box 1, and the detection unit is used to detect the weight of onions in the feed bin 2, a dryer 3 is provided inside the drying box 1, and a feeding unit is provided on the dryer 3, and the feeding unit is used to make the onions spirally roll from the feed port 11 to the discharge port 12, so that in the process of drying and feeding the onions, the onions are detected by the detection unit. The unit detects the weight of onions in the feed bin 2. When it is detected that all the onions in the feed bin 2 enter the drying box 1 through the feed pipe 21, the weight detected by the detection unit reaches the minimum, and then the feeding device is automatically controlled to add the onions into the feed bin 2. When it is detected that the onions in the feed bin 2 are stuck at the feed pipe 21, the weight detected by the detection unit will remain unchanged for a long time, and then the staff will be automatically notified to clean up the onions stuck at the feed pipe 21. At the same time, the onions are spirally rolled from the feed port 11 to the discharge port 12 through the feeding unit, so that the onions will not be damaged due to collision during the rolling process.

[0027] like Figures 1 to 3 As shown, the detection unit includes a support cylinder 4, a support rod 41 and a pressure detector 42. The support cylinder 4 is arranged in a circular array on the top surface of the drying box 1, and the support rod 41 is arranged in a circular array on the bottom surface of the feed bin 2. The bottom end of the support rod 41 slides and extends to the inside of the support cylinder 4. The pressure detector 42 is arranged in the inside of the support cylinder 4. A conduction component is provided between the pressure detector 42 and the support rod 41, so that the pressure detector 42 detects the weight of onions inside the feed bin 2 through the cooperation of the support cylinder 4, the support rod 41 and the conduction component.

[0028] like Figures 1 to 3 As shown, the conduction component includes a conduction block 43 and a conduction spring 44. The conduction block 43 is arranged at the bottom end of the support rod 41, and the conduction spring 44 is arranged between the conduction block 43 and the detection end of the pressure detector 42, so that the weight of the onions inside the feed bin 2 is transmitted to the detection end of the pressure detector 42 through the cooperation of the conduction block 43 and the conduction spring 44.

[0029] like Figure 2 As shown, a guide block 22 is provided inside the feed bin 2 , and a feed slope 23 is provided on the guide block 22 , so that the onions inside the feed bin 2 can roll down to the inside of the feed pipe 21 through the feed slope 23 on the guide block 22 .

[0030] like Figure 2 and Figure 4As shown, the feeding unit includes a feeding rod 5 and a feeding net 51. The feeding rod 5 is arranged at the center of the top surface of the dryer 3, and the feeding net 51 is spirally arranged between the feeding rod 5 and the inner wall of the drying box 1, so that through the cooperation of the feeding rod 5 and the feeding net 51, the onions are spirally rolled from the feed port 11 to the discharge port 12.

[0031] like Figure 2 , Figure 4 and Figure 5 As shown, a guide plate 52 is provided on the top surface of the dryer 3, the top surface of the guide plate 52 is connected to the feeding net 51, and the two side surfaces of the guide plate 52 are respectively connected to the feeding rod 5 and the inner wall of the drying box 1, so that the onions transported by the feeding net 51 roll down to the discharge port 12 through the guide plate 52.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, a discharge pipe 53 is provided on the side of the drying box 1, and the discharge pipe 53 is connected to the discharge port 12. A discharge slope 54 is provided on the discharge pipe 53, so that the onions at the discharge port 12 roll down to the inside of the collecting device through the discharge slope 54 on the discharge pipe 53.

[0033] Working principle: When the feeding device adds onions into the feed bin 2, the feed bin 2 will drive the support rod 41 to slide into the support tube 4 under the weight of the onions. When the support rod 41 slides into the support tube 4, it will drive the conduction block 43 to squeeze the conduction spring 44. When the conduction spring 44 is squeezed, it will transmit the force to the detection end of the pressure detector 42. When the weight detected by the pressure detector 42 reaches the maximum predetermined value, the feeding device can be automatically controlled to stop adding onions into the feed bin 2. The onions in the feed bin 2 will pass through the feed slope 23 on the guide block 22. The onions roll down to the inside of the feed pipe 21 and enter the inside of the drying box 1 through the feed port 11. During this process, the weight detected by the pressure detector 42 gradually decreases. When the weight detected by the pressure detector 42 reaches the minimum predetermined value, the feeding device can be automatically controlled to start adding onions to the inside of the feed bin 2, thereby achieving the effect of automatic control of feeding. When the weight detected by the pressure detector 42 does not change for a long time, it means that the onions are stuck at the feed pipe 21, thereby automatically notifying the staff to clean up the onions stuck at the feed pipe 21.

[0034] The onions entering the drying box 1 will fall on the feeding net 51, and the onions falling on the feeding net 51 will roll in a spiral shape along the feeding net 51 from the feeding port 11 to the discharging port 12. At this time, the dryer 3 will dry the onions rolling on the feeding net 51, and the dried onions will roll down to the discharging port 12 through the guide plate 52, and finally roll down to the inside of the collecting device through the discharging slope 54 on the discharging pipe 53.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
