DETAILED DESCRIPTION
[0017] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model will be described more clearly and more completely in combination with the drawings in the embodiment, and of course the described embodiment is only a part of the utility model but not all, based on this embodiment, the technical personnel in the art obtain other embodiments without paying the creative labor intensity, and all are within the protection scope of the utility model.
[0018] As Figure 1As shown in the figure, a nut production swing drying furnace, including unloading frame 1, drying work box 2 and combustion furnace 3; the drying work box 2 is respectively provided with feeding bin 2a and discharge slope 2b; drying work box 2 and combustion furnace 3 are provided with heat supply pipeline 4 connected with both. Combustion furnace 3 supplies heat to drying work box 2 through heat supply pipeline 4. Feeding bin 2a and discharge slope 2b are used for nut feeding and release respectively. Unloading frame 1 is located in the front side of discharge slope 2b.
[0019] As shown in the figure, Figures 2 to 4 The drying work box 2 is provided with a slidable base plate 5, and the base plate 5 is provided with a loading box 6. The loading box 6 is provided with a swing plate 7, and the swing plate 7 is connected with a transfer shaft 8. The transfer shaft 8 is connected with a swing control assembly. The front and rear ends of the swing plate 7 are in contact with the inner side wall of the loading box 6. The swing control assembly can control the front and rear parts of the swing plate 7 to swing continuously.
[0020] As shown in the figure, Figure 2 The transfer shaft 8 is installed on the loading box 6 through a bearing. The above is a conventional design of shaft rotation structure.
[0021] As shown in the figure, Figure 4 The swing plate 7 is provided with a penetrating slot 7a, and two extension plates 9 are slidably installed in the penetrating slot 7a. The two extension plates 9 are connected with a spring 10. The two extension plates 9 are provided with arc surfaces on the side away from the spring 10. The spring 10 is always in a compressed state, and under the action of the elastic force, the arc surfaces of the two extension plates 9 are in contact with the inner side of the loading box 6. The elastic expansion and contraction of the two extension plates 9 can ensure that the nuts carried on the swing plate 7 and the two extension plates 9 will not fall off when the swing plate 7 swings. The gap between each extension plate 9 and the left and right side walls of the loading box 6 is relatively small, so that the nuts will not fall from the gap.
[0022] As shown in the figure, Figure 2 And Figure 4 The front end of the loading box 6 is provided with a blocking plate 11 which is installed in a horizontal sliding manner, and the blocking plate 11 is connected with a cylinder 12 which is fixedly installed on the outside of the loading box 6. Specifically, the front side of the loading box 6 is provided with a notch, and the blocking plate 11 is slidably installed in the notch. In order to facilitate the unloading of nuts, the lower end of the notch can be provided as an inclined surface.
[0023] As shown in the figure, Figure 2 And Figure 5 The drying work box 2 is respectively provided with a hydraulic cylinder 13 and a three-guide rod 14; the hydraulic cylinder 13 is connected with the base plate 5; the three-guide rod 14 is in sliding cooperation with the base plate 5. The above is a conventional design of sliding structure, that is, the whole base plate 5 and the loading box 6 can be controlled to move horizontally.
[0024] As shown in the figure, Figure 5As shown, the swing control assembly is composed of a straight gear 15 connected with the intermediate shaft 8, a rack 16 engaging the straight gear 15, and a slider-crank structure connecting the rack 16. That is, through the slider-crank structure, the rack 16 can be controlled to reciprocate and swing the swing board 7 under the action of the gear and rack.
[0025] As shown, Figure 5 As shown, the base plate 5 is provided with a linear slot 5a in which the rack 16 is slidingly installed. The above-mentioned sliding structure is a conventional design.
[0026] As shown, Figure 5 The swing control assembly includes a motor 17 installed on the base plate 5 and a rocker 18 connected with the motor 17. A transmission rod 19 is hingedly connected between the rack 16 and the rocker 18. The motor 17 drives the rocker 18 to rotate, and under the transmission of the transmission rod 19, the rack 16 can reciprocate.
[0027] In the initial state, the loading box 6 is located directly below the feeding bin 2a.
[0028] In specific use, the user only needs to put the nuts from the feeding bin 2a so that the nuts fall onto the swing board 7 and the two extension plates 9.
[0029] Further, the left push of the hydraulic cylinder 13 drives the loading box 6 to move to the position below the pipe orifice at the rear of the heating pipeline 4, and at this time, the loading box 6 is located at the rear side of the discharge slope 2b.
[0030] Further, while the nuts in the loading box 6 are dried by the hot gas from the combustion furnace 3, the motor 17 drives the rocker 18 to rotate, which promotes the rack 16 to reciprocate, and under the transmission of the gear and rack, the swing board 7 and the two extension plates 9 can reciprocate, so that the nuts are dried in the process of continuous tumbling.
[0031] When the drying is completed, the cylinder 12 pulls open the sealing plate 11, so that the dried nuts fall onto the discharge frame 1 through the gap at the front side of the loading box 6 and the discharge slope 2b in sequence, and the discharging is completed.
[0032] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only the principles of the present application.
