Detailed Implementation

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0046] Please see Figures 1-5 The present invention provides the following technical solution: a modular and expandable compost bin structure, including a base 1, a discharge port 11 on the base 1, and further including: multiple cylinders 2, a top cover 3 and a fixing mechanism 4.

[0047] Furthermore, by Figure 1 As shown in this embodiment, multiple cylinders 2 are stacked and arranged on the top of the base 1, and the top cover 3 is hinged to the top of the cylinder 2. Two adjacent cylinders 2 are fixedly connected by a fixing mechanism 4, and the cylinder 2 is fixedly connected to the base 1 by the fixing mechanism 4. After adopting the above scheme, when using it, the number of cylinders 2 to be installed is determined according to the composting requirements. The cylinders 2 are fixed to the top of the base 1 by the fixing mechanism 4, and different cylinders 2 are stacked and fixedly connected by the fixing mechanism 4 to form a silo. The top cover 3 is hinged to the top of the cylinder 2.

[0048] When adding solid fertilizer, open the top cover 3 and put the solid fertilizer into the silo from the top of the silo in sequence, and then close the top cover 3.

[0049] When the compost reaches the maturity standard, open the box door of the discharge port 11 and take out the solid fertilizer from the discharge port 11.

[0050] This invention adjusts the volume of the silo by increasing or decreasing the number of cylinders 2, adapting to different sizes of large-scale composting scenarios and avoiding space waste.

[0051] Optionally, by Figure 1 and Figure 2As shown, in this embodiment, the fixing mechanism 4 includes: a flip screw 41, a fixing block 42, and a wing nut 43. The flip screw 41 is hinged to the top of the outer side of both the base 1 and the cylinder 2. The fixing block 42 is fixed to the bottom of the outer side of the cylinder 2, and a notch 421 for the flip screw 41 to pass through is provided on the fixing block 42. The wing nut 43 is installed on the protruding end of the flip screw 41 by thread engagement. With the above solution, when in use, the installer can quickly flip the flip screw 41 to the position of the notch 421 of the fixing block 42 through the hinge structure, so that the axis of the flip screw 41 is aligned with the vertical direction of the cylinder 2.

[0052] Then, tighten the wing nut 43 at the extended end of the flip screw 41 to press the upper and lower cylinders 2 or the contact surface of the cylinder 2 and the base 1 tightly together to form a stable rigid connection.

[0053] During disassembly, simply rotate the wing nut 43 in the opposite direction. After the wing nut 43 disengages from the threaded section of the flip screw 41, flip the flip screw 41 towards the hinge axis to release the locking state of the two-layer structure. The entire process requires no tools and can be completed by a single person.

[0054] Preferably, by Figure 1 As shown, in this embodiment, it further includes: a drain outlet 6, which is fixed to the bottom of the outer side of the base 1, and a manual valve 7 is installed on the drain outlet 6. After adopting the above scheme, when in use, the operator opens the manual valve 7 periodically to discharge the liquid. In the initial composting stage, due to the high moisture content of the raw materials and the active metabolism of microorganisms, the amount of leachate discharged is large, and the manual valve 7 can be opened daily to discharge the leachate.

[0055] When the compost enters the maturation stage, manual valve 7 needs to be closed to maintain a suitable moisture content in the silo and promote the later humification process of microorganisms.

[0056] Preferably, by Figure 1 and Figure 4 As shown, this embodiment further includes: a positioning cylinder 23, which is fixed to the bottom of the cylinder 2, and the inner wall of the positioning cylinder 23 is flush with the inner wall of the cylinder 2. A positioning groove 24 for the positioning cylinder 23 to be inserted is provided on the top of the inner side of the cylinder 2. With the above solution, the cooperation structure of the positioning cylinder 23 and the positioning groove 24 can realize the rapid and accurate alignment of the upper and lower cylinders 2 during use (it should be noted that a positioning groove 24 for the positioning cylinder 23 to be inserted is also provided on the top of the inner side of the base 1).

[0057] During installation, simply align the positioning cylinder 23 of the upper cylinder 2 with the positioning groove 24 of the lower cylinder 2 and drop it vertically. It will automatically embed into the positioning groove 24 under the action of gravity, which significantly improves the installation efficiency of multi-layer stacking.

[0058] Preferably, by Figure 1 and Figure 4 As shown, this embodiment further includes: multiple first connecting blocks 25 and multiple second connecting blocks 26. The multiple first connecting blocks 25 are fixed at equal intervals along the circumferential direction to the bottom of the outer wall of the cylinder 2, and a positioning rod 251 is fixed on the bottom surface of the first connecting block 25. The multiple second connecting blocks 26 are fixed at equal intervals along the circumferential direction to the top of the outer wall of the cylinder 2, and a positioning hole 261 for the positioning rod 251 to pass through is opened on the second connecting block 26. With the above solution, when multiple cylinders 2 need to be stacked, the cooperation of the first connecting blocks 25 and the second connecting blocks 26 can further improve the stability and accuracy of the connection between the cylinders 2.

[0059] When the installer is stacking the cylinders 2, he only needs to place the No. 1 connecting block 25 of the upper cylinder 2 corresponding to the No. 2 connecting block 26 of the lower cylinder 2, so that the positioning rod 251 is aligned with the positioning hole 261, and then slowly lower the upper cylinder 2. The positioning rod 251 will then be smoothly inserted into the positioning hole 261. (It should be noted that multiple No. 2 connecting blocks 26 are also fixed on the top of the outer wall of the base 1.)

[0060] Since the No. 1 connecting block 25 and the No. 2 connecting block 26 are evenly distributed along the circumference, this uniform force design ensures the stability of the cylinder 2 in all directions after stacking.

[0061] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, it further includes: a third connecting block 31, a perforated block 32, a perforated mounting ear 22, a locking bolt 8, and a locking nut 9. The third connecting block 31 is fixed to the outer wall of the top cover 3 and corresponds to the second connecting block 26. A threaded hole 311 is machined on the third connecting block 31. The perforated block 32 is fixed to the outer wall of the top cover 3. The perforated mounting ear 22 is fixed to the outer wall of the cylinder 2. The locking bolt 8 passes through the perforated mounting ear 22 and the perforated block 32. The locking nut 9 is installed on the protruding end of the locking bolt 8 by threaded engagement. With the above scheme, when in use, the top cover 3 is hinged by the cooperation of the third connecting block 31, the perforated block 32, the perforated mounting ear 22, the locking bolt 8, and the locking nut 9. The top cover 3 can rotate about the locking bolt 8 as the axis.

[0062] When multiple cylinders 2 need to be stacked, the top cover 3 can be removed simply by unscrewing the locking nut 9, and then the top cover 3 can be installed on the topmost cylinder 2.

[0063] Preferably, by Figure 1 and Figure 5As shown, in this embodiment, a stirring mechanism 5 is further included, which includes a conical disk 51, a drive motor 52, and a stirring block 53. The conical disk 51 is rotatably installed in the base 1, the drive motor 52 is fixed to the bottom of the base 1 and is used to drive the conical disk 51 to rotate, and the stirring block 53 is fixed to the top surface of the conical disk 51. With the above solution, the stirring mechanism 5 can realize the dynamic mixing and oxygen supply of compost materials during use, which significantly improves the fermentation efficiency.

[0064] The drive motor 52 is connected to the central shaft of the conical disk 51 via a coupling. After initial feeding, the drive motor 52 is started, and the conical disk 51 drives the stirring block 53 to rotate, stirring the fertilizer and making the fertilizer fully contact the air in the silo to meet the metabolic needs of aerobic microorganisms.

[0065] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, it further includes: a viewing window 21, which is fixed to the outer wall of the cylinder 2. The viewing window 21 can realize the visual monitoring of the composting process, significantly improving the convenience of operation and the controllability of the process.

[0067] The working principle and usage process of this utility model: When using the compost bin structure of this utility model, the number of cylinders 2 to be installed is determined according to the composting needs. The cylinders 2 are fixed to the top of the base 1 using the fixing mechanism 4. Different cylinders 2 are stacked and fixedly connected using the fixing mechanism 4 to form a bin. The top cover 3 is hinged to the top of the cylinder 2.

[0068] When adding solid fertilizer, open the top cover 3, put the solid fertilizer into the silo from the top of the silo in sequence, and then close the top cover 3.
