Description

Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to an organic composting device. Background Art

[0002] Composting is a biochemical process that utilizes naturally occurring microorganisms to controllably transform biodegradable organic matter in solid waste into stable humus. During composting, the compost bin is a closed or semi-closed environment where controlled conditions such as humidity, oxygen, and temperature promote the growth and reproduction of microorganisms, thereby accelerating the decomposition of organic waste.

[0003] During the composting process, aerobic fermentation microorganisms need sufficient oxygen to carry out their growth activities. The operation of the ventilation fan can continuously provide fresh air to the inside of the compost bin, ensuring that the microorganisms obtain sufficient oxygen, thereby promoting their growth and reproduction. However, when the ventilation fan on the compost bin is used, the size of its air outlet is fixed, so the ventilation volume of the ventilation fan is certain. At different stages of composting, the microorganisms' demand for oxygen and the temperature, humidity and other conditions inside the pile are changing. A fixed ventilation volume cannot ensure that the composting process is always in the best condition. Utility Model Content

[0004] The utility model aims to provide an organic composting device in order to solve the problem that the ventilation volume of the existing composting box is fixed during use and accurate control of the ventilation volume cannot be achieved.

[0008] As a further description of the above technical solution: a sliding groove that matches the second orifice plate is opened on the inner wall of the installation cylinder.

[0009] As a further description of the above technical solution: the interior of the ventilation pipe is provided with a porous plate through an annular positioning plate, and the porous plate is made of activated carbon.

[0010] As a further description of the above technical solution: a locking nut is provided on the positioning plate through a threaded end, and a socket matching the threaded end is provided near the edge of the porous plate.

[0011] As a further description of the above technical solution: a flip cover is hingedly connected to the top of the ventilating pipe, and a handle is fixedly installed on the top of the flip cover.

[0012] As a further description of the above technical solution: the turning assembly includes a motor group arranged outside the compost box through a fixed frame, a connecting shaft is fixedly connected to the output end of the motor group, and a stirring blade located inside the compost box is provided on the connecting shaft.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] By adjusting the size of the ventilation fan's air outlet, the ventilation volume can be precisely controlled.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-Figure 7 The present embodiment provides an organic composting device, comprising a composting bin 1, a turning assembly 2 provided near the bottom of the composting bin 1, a ventilation mechanism 3 capable of adjusting the size of ventilation holes provided on one side of the top of the composting bin 1, a cover plate 4 provided on the top of the composting bin 1, and a ventilation pipe 5 connected to the composting bin 1 and capable of absorbing odors provided on the cover plate 4.

[0027] In the present invention, when composting, the composting materials are placed in the composting bin 1 and covered with a cover plate 4. The turning assembly 2 on the composting bin 1 stirs the materials so that the microorganisms can be more evenly distributed in the composting materials, thereby avoiding the situation of excessive reproduction or deficiency of local microorganisms and ensuring the smooth progress of the entire composting process. At different stages of composting, the demand for oxygen by the microorganisms and the temperature, humidity and other conditions inside the compost body are changing. The ventilation amount can be adjusted by the ventilation mechanism 3. The flexible ventilation amount adjustment can ensure that the composting process is always in the best state. The ventilator 5 on the composting bin 1 is used for ventilation to ensure the air circulation of the composting bin 1.

[0028] It should be noted that the ventilation mechanism 3 can adjust the size of the ventilation holes, and the ventilation pipe 5 can also be closed. Therefore, the compost bin 1 can be adjusted to a closed state or a semi-closed state according to usage needs.

[0029] Specifically, such as Figure 1-Figure 3 As shown, the ventilation mechanism 3 includes a mounting cylinder 31 connected to the interior of the compost bin 1, a ventilation fan 32 is provided at the rear end of the mounting cylinder 31, a first orifice plate 33 is provided at the front end of the mounting cylinder 31, and a second orifice plate 34 is provided on the mounting cylinder 31 to be in contact with the first orifice plate 33 and slidable. A sliding groove is provided on the inner wall of the mounting cylinder 31 to cooperate with the second orifice plate 34.

[0030] Among them, the ventilation fan 32 is set at the ventilation position of the compost bin 1 through the mounting tube 31. The wind of the ventilation fan 32 passes through the openings of the first orifice plate 33 and the second orifice plate 34 and is blown into the compost bin 1 for ventilation. At different stages of composting, when the demand for oxygen by microorganisms and the temperature, humidity and other conditions inside the compost body change, the second orifice plate 34 can be pulled to move. When the second orifice plate 34 moves, the opening of the second orifice plate 34 is misaligned with the opening of the first orifice plate 33, thereby realizing the adjustment of the size of the ventilation opening, so that the ventilation volume of the ventilation fan 32 can be flexibly adjusted, thereby ensuring that the composting process is always in the best state.

[0031] Specifically, such as Figure 2-Figure 4 As shown, a positioning assembly 36 for limiting and fixing the second orifice plate 34 is provided on the mounting cylinder 31, and the positioning assembly 36 includes a sleeve 361, a locking bolt 363 is provided on the sleeve 361 through a bolt seat 362, and a pressure plate 364 is provided at one end of the locking bolt 363, and a handle 35 is provided on the second orifice plate 34.

[0032] Among them, when it is necessary to move the position of the second orifice plate 34 to adjust the size of the vent, the locking bolt 363 on the jacket 361 is loosened to reduce the pressure of the pressure plate 364 on the second orifice plate 34, and then the second orifice plate 34 is pulled by the handle 35 to move the second orifice plate 34, and then the vent is adjusted by misaligning the orifice of the second orifice plate 34 and the first orifice plate 33. After adjustment, the locking bolt 363 is tightened again to make the pressure plate 364 press and fix the second orifice plate 34 to fix the position of the second orifice plate 34.

[0033] Specifically, such as Figure 1 and Figure 5 As shown, the interior of the vent pipe 5 is provided with a porous plate 52 through an annular positioning plate 51, and the porous plate 52 is made of activated carbon. A locking nut 54 is provided on the positioning plate 51 through a threaded end 53, and a socket is provided near the edge of the porous plate 52 to match the threaded end 53.

[0034] Among them, the porous plate 52 made of activated carbon has an adsorption effect. During the ventilation process of the ventilation pipe 5, the odor generated by the compost can be adsorbed by the porous plate 52, thereby effectively reducing the odor generated by the compost. When the porous plate 52 needs to be disassembled for replacement and cleaning, the locking nut 54 on the threaded end 53 is removed, and then the porous plate 52 is pulled out and removed from the positioning plate 51, which facilitates the installation and disassembly of the porous plate 52.

[0035] Specifically, such as Figure 1 and Figure 6 As shown, a flap 55 is hingedly connected to the top of the vent tube 5, and a handle 56 is fixedly mounted on the top of the flap 55. When the compost bin 1 needs to be sealed, the second orifice plate 34 is moved so that the openings of the second orifice plate 34 and the first orifice plate 33 are staggered and sealed. The flap 55 on the vent tube 5 is operated by the handle 56 to close the vent tube 5. At this time, the compost bin 1 can be switched between closed states, allowing the compost bin 1 to meet different needs.

[0036] Specifically, such as Figure 1 and Figure 7 As shown, the turning assembly 2 includes a motor group 22 arranged outside the compost bin 1 through a fixing frame 21, a connecting shaft 23 is fixedly connected to the output end of the motor group 22, and a stirring blade 24 located inside the compost bin 1 is provided on the connecting shaft 23.

[0037] When the compost raw materials in the compost bin 1 need to be turned over, the motor group 22 on the fixed frame 21 starts to drive the stirring blades 24 on the connecting shaft 23 to rotate, thereby achieving the stirring and turning of the compost raw materials in the compost bin 1. Through stirring, the microorganisms can be more evenly distributed in the compost material, thereby avoiding the over-reproduction or lack of local microorganisms and ensuring the smooth progress of the entire composting process.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
