Description

Technical Field

[0001] This utility model relates to the field of flue-cured tobacco base fertilizer processing technology, specifically a device for premixing different fertilizers in flue-cured tobacco base fertilizer. Background Technology

[0002] Currently, the base fertilizer for flue-cured tobacco requires the application of various types of fertilizers, primarily in powder form, typically 3 to 6 different types, such as base fertilizer, oilseed cake, phosphate fertilizer, and potash fertilizer. The proportions of these fertilizers vary depending on soil fertility, the previous crop, and cultivation methods. Currently, the preparation of base fertilizer for flue-cured tobacco largely relies on the experience of tobacco farmers, involving manually mixing the various fertilizers after unpacking each bag (each bag has a fixed weight). This process is labor-intensive, inefficient, and generally results in uneven mixing.

[0003] To address the aforementioned issues, an improved device for premixing different fertilizers as base fertilizer for flue-cured tobacco is now designed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 In this embodiment of the present invention, a device for premixing different fertilizers for flue-cured tobacco base fertilizer includes a mixing box 1, a support box 2 installed at the lower end of the mixing box 1, a collection frame 4 installed at the upper end of the mixing box 1, a fixing frame 8 installed at the upper end of the collection frame 4, the inner cavity of the mixing box 1 being round at the top and bottom, a discharge pipe 15 installed at the lower end of the side wall of the mixing box 1, a controller installed on the side wall of the mixing box 1, a feeding and weighing mechanism for conveying and weighing different fertilizers on the fixing frame 8, and a mixing mechanism for mixing and stirring the fertilizers inside the mixing box 1.

[0024] The feeding and weighing mechanism includes a first rotating rod 11, which is horizontally arranged at the center of the fixed frame 8. One end of the first rotating rod 11 passes through the fixed frame 8 and is equipped with a first motor 7. The first motor 7 is installed on the side wall of the fixed frame 8. The end of the first rotating rod 11 away from the first motor 7 is rotatably connected to the inner wall of the fixed frame 8. Several support frames 10 are installed on the first rotating rod 11.

The lower end of the holding frame 9 is placed on the measuring end of the weight sensor 14. A sliding groove 12 is provided on the inner wall of the support frame 10. A slider 13 that cooperates with the sliding groove 12 is installed on the side wall of the holding frame 9. The slider 13 is slidably connected to the inner wall of the sliding groove 12. A feeding component for conveying fertilizer into the holding frame 9 is provided at the upper end of the fixed frame 8.

[0026] The feeding assembly includes several fertilizer boxes 3 corresponding one-to-one with the holding frames 9. The fertilizer boxes 3 are placed on the ground. A lifting auger 5 is vertically installed on the side wall of the fertilizer box 3 near the mixing box 1. The input end of the lifting auger 5 is connected to the lower end of the inner wall of the fertilizer box 3. An output pipe 6 is installed at the output end of the lifting auger 5. The end of the output pipe 6 away from the lifting auger 5 is installed on the top of the fixed frame 8. The output pipe 6 corresponds one-to-one with the holding frames 9. The output end of the output pipe 6 is located directly above the holding frames 9. A guide block 20 is installed at the bottom of the fertilizer box 3 to guide and transport the fertilizer at the bottom of the fertilizer box 3 to the input end of the lifting auger 5.

[0027] In use, the staff adds different fertilizers into different fertilizer bins 3, and then starts the lifting auger 5 to lift and transport the fertilizer inside the fertilizer bin 3 to the output pipe 6. The output pipe 6 transports the fertilizer to the corresponding holding frame 9. The weight sensor 14 weighs the fertilizer inside the holding frame 9. When the specified fertilizer weight is reached, the weight sensor 14 sends a signal to the controller, and the controller stops the corresponding lifting auger 5.

[0028] After all the holding frames 9 have been filled, the first motor 7 is started. The output end of the first motor 7 drives the first rotating rod 11 and the support frame 10 to rotate 180 degrees. The support frame 10 drives the holding frames 9 to rotate. The holding frames 9 pour the fertilizer inside into the collecting frame 4. The collecting frame 4 collects different fertilizers and transports them into the mixing box 1. Then the support frame 10 and the holding frames 9 are reset.

[0029] The mixing mechanism includes a second motor 16, which is installed at the center of the bottom of the support box 2. A second rotating rod 18 is vertically installed at the output end of the second motor 16. The upper end of the second rotating rod 18 passes through the bottom of the mixing box 1 and is located at the top of the mixing box 1. Several stirring rods 19 for stirring are installed on the side wall of the second rotating rod 18 inside the mixing box 1. A pusher plate 17 for pushing the mixed fertilizer toward the discharge pipe 15 is installed on the side wall of the second rotating rod 18 near the bottom of the mixing box 1. The lower end of the pusher plate 17 is in close contact with the bottom of the mixing box 1.

[0030] When in use, start the second motor 16. The output end of the second motor 16 drives the second rotating rod 18 to rotate. The second rotating rod 18 drives the stirring rod 19 to rotate. The stirring rod 19 mixes and stirs the fertilizer inside the mixing box 1. After the mixing is completed, open the discharge pipe 15. The pusher plate 17 pushes the mixed fertilizer to the discharge pipe 15 and outputs the mixed fertilizer through the discharge pipe 15.

[0031] The working principle of a device for premixing different fertilizers as base fertilizer for flue-cured tobacco:

[0032] In use, the staff adds different fertilizers into different fertilizer bins 3, and then starts the lifting auger 5 to lift and transport the fertilizer inside the fertilizer bin 3 to the output pipe 6. The output pipe 6 transports the fertilizer to the corresponding holding frame 9. The weight sensor 14 weighs the fertilizer inside the holding frame 9. When the specified fertilizer weight is reached, the weight sensor 14 sends a signal to the controller, and the controller stops the corresponding lifting auger 5.

[0033] After all the holding frames 9 have been filled, the first motor 7 is started. The output end of the first motor 7 drives the first rotating rod 11 and the support frame 10 to rotate 180 degrees. The support frame 10 drives the holding frames 9 to rotate. The holding frames 9 pour the fertilizer inside into the collecting frame 4. The collecting frame 4 collects different fertilizers and transports them into the mixing box 1. Then the support frame 10 and the holding frames 9 are reset.

[0034] Start the second motor 16. The output end of the second motor 16 drives the second rotating rod 18 to rotate. The second rotating rod 18 drives the stirring rod 19 to rotate. The stirring rod 19 mixes and stirs the fertilizer inside the mixing box 1. After the mixing is completed, open the discharge pipe 15. The pusher plate 17 pushes the mixed fertilizer to the discharge pipe 15 and outputs the mixed fertilizer through the discharge pipe 15.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
