Description

Technical Field

[0001] The invention belongs to the technical field of composting devices, and in particular relates to a biofertilizer composting device based on the addition of bacterial agents. Background Art

[0002] The biofertilizer composting device is a special equipment that efficiently converts organic waste into high-quality fertilizer. Through the natural fermentation process of microorganisms, organic matter such as animal and plant residues, agricultural waste, and urban organic waste are converted into biofertilizer rich in nutrients required by plants under specific environmental conditions.

[0003] The main purpose of adding bacterial agents during the biofertilizer composting process is to utilize the activity of microorganisms to accelerate the decomposition of organic waste and improve the efficiency and quality of composting. Bacterial agents can optimize the composting microecological environment, promote the reproduction of beneficial microorganisms, inhibit the growth of harmful microorganisms and pathogens, and reduce the generation of odorous substances.

[0004] Patent CN110937935A discloses a fertilizer preparation device for greening trees, which is convenient for delivering oxygen to a fermentation box so that the raw materials can be composted and fermented, and is also convenient for temperature regulation. The fertilizer preparation efficiency is high. However, when the microbial agent particles are added to the fertilizer preparation tank, the microbial agent particles cannot be evenly sprinkled on the biomass raw materials. The microbial agent particles will agglomerate, and when the biomass raw materials are stirred and the biomass raw materials and the microbial agent particles are mixed, some of the biomass raw materials will have too many microbial agent particles, and the other part of the biomass raw materials will have fewer microbial agent particles. In this case, the compost quality cannot be guaranteed, and the compost efficiency cannot be guaranteed.

[0005] During composting, there is also the problem of being unable to spread the bacterial agent, dry matter or water to different layers of the biomass raw materials, making it impossible for the bacterial agent, dry matter or water to be fully and evenly mixed with the biomass raw materials. Some biomass raw materials may even have too much water, causing the biomass raw materials to clump, thereby failing to guarantee the compost quality and composting efficiency.

[0019] Beneficial effects of the present invention:

[0020] In the present invention, the inoculant particles or dry matter are added into the first feeding pipe during the rotation of the outer gear ring. After the inoculant particles or dry matter contact the deceleration plate, the descending speed is slowed down to avoid the accumulation of the inoculant particles or dry matter. After the inoculant particles or dry matter contact the table-shaped groove block, the inoculant particles or dry matter fall in the center and then fall onto the distribution column. The distribution column evenly distributes the inoculant particles or dry matter to each area of ​​the spreading box. A part of the inoculant particles or dry matter falls into the middle of the compost material through the discharge hole. Another part of the inoculum particles or dry matter will fall from the discharge port in cooperation with the guide block under the action of the angle between the bottom of the spreading box and the horizontal plane, and another part of the inoculum particles or dry matter will first fall into the first receiving plate. After the inoculum particles or dry matter in the first receiving plate reaches a certain weight, the first receiving plate will rotate. After the first receiving plate rotates 33°, an angle of 3° will be formed between the first receiving plate and the horizontal plane. Under the action of the angle and the gravity of the inoculum particles or dry matter themselves, the inoculum particles or dry matter will The second receiving plate will rotate 33° synchronously with the first receiving plate, and will contact the spreading box after rotating 33°. At this time, another part of the inoculum particles or dry matter will fall onto the second receiving plate, and through the cooperation of the baffle, the inoculum particles or dry matter will fall to the position of the periphery of the compost material. After the inoculum particles or dry matter in the first receiving plate fall, the first receiving plate will cooperate under the action of the torsion spring, so that another part of the inoculum particles or dry matter will fall into the first receiving plate again, and the above-mentioned action will be repeated. During the rotation of the outer gear ring, the spreading box will be driven to rotate, so that centrifugal force will be generated when the inoculum particles or dry matter fall. Under the action of the centrifugal force, the inoculum particles or dry matter will be evenly spread on the upper surface of the compost material, so that the inoculum particles or dry matter can be evenly spread, so that the inoculum particles or dry matter can be evenly mixed with the compost material, which can speed up the composting efficiency and improve the composting quality of the fertilizer.

[0021] The present invention drives the second rotating rod and the auger blades to rotate during the rotation of the material spreading box. The auger blades transfer the compost material at the bottom of the compost tank to the top of the compost tank during the rotation, thereby achieving the purpose of spreading the bacterial agent particles, dry matter or water to different layers of the compost material, so that the bacterial agent particles, dry matter or water can be evenly mixed with the compost material, the compost material will not be agglomerated, and the compost quality and compost efficiency can be guaranteed.

[0022] The present invention starts a motor to drive the second gear to rotate, and the rotation of the second gear drives the outer gear ring to rotate.

The first gear rotates around the outer gear ring and rotates on its own, and at the same time, the first gear drives the first rotating rod to rotate around the outer gear ring and rotate on its own, so that the horizontal rod and the vertical rod rotate around the outer gear ring and rotate on their own, thereby achieving the purpose of fully and evenly stirring the compost material, so that the compost material can be fully and evenly mixed with water, bacterial agent particles or dry matter.

[0049] A second feed pipe 13 arranged obliquely is connected to the top of the compost tank 1 , and materials required for composting can be added into the compost tank 1 through the second feed pipe 13 . In order to speed up the composting efficiency, the materials need to be broken up before being added into the compost tank 1 .

[0050] One end of the second feed pipe 13 away from the compost tank 1 is threadedly connected with a second cover 14 for closing the second feed pipe 13 so that the temperature in the compost tank 1 is not affected by the outside world.

[0051] An annular water pipe 15 is connected to the upper part of the compost tank 1 corresponding to the second feed pipe 13, and a plurality of inclined atomizing nozzles 16 are connected to the lower part of the annular water pipe 15. Through the cooperation of the annular water pipe 15 and the atomizing nozzles 16, water can be evenly sprinkled on the compost material to prevent the situation where some positions have insufficient water and some positions have excessive water. The positions with insufficient water cannot meet the composting conditions, and the positions with excessive water will form lumps. In order to ensure the progress of composting, water needs to be fully and evenly sprinkled on the compost material.

[0055] An outer gear ring 2 is arranged on the upper part of the composting tank 1 , and a plurality of L-shaped positioning blocks 201 are connected to the upper part of the outer gear ring 2 for fixing the position of the outer gear ring 2 .

[0056] A positioning ring 202 is connected to the position of the positioning block 201 at the top of the compost tank 1. A circular positioning groove 203 is opened above the positioning ring 202 corresponding to the positioning block 201. The top of the positioning block 201 is rotatably connected in the positioning groove 203.

The first gear 21 is meshed with the inner gear ring 24. Through the cooperation between the inner gear ring 24 and the outer gear ring 2, when the outer gear ring 2 rotates, the first gear 21 can rotate around the outer gear ring 2 and the inner gear ring 24 while also being able to rotate on its own.

[0058] A second gear 22 is meshed on the outer side of the outer gear ring 2 , and the second gear 22 is used to drive the outer gear ring 2 to rotate.

[0059] A motor 23 is connected to a position on the upper surface of the compost tank 1 corresponding to the second gear 22 . The rotating shaft of the motor 23 passes through the top of the compost tank 1 and is connected to the second gear 22 . The motor 23 is used to drive the second gear 22 to rotate.

[0060] The first gear 21 and the second gear 22 are alternately arranged on the outside of the outer gear ring 2, and the second gear 22 is located above the first gear 21. This arrangement can prevent the first rotating rod 3 from affecting the second gear 22.

[0061] A first rotating rod 3 is connected to the middle of the lower surface of the first gear 21 , and a plurality of evenly arranged cross bars 31 are connected to the outer side of the first rotating rod 3 . The cross bars 31 are used to stir the compost material.

[0062] One end of the cross bar 31 away from the first rotating rod 3 is connected to a vertical rod 32 , and the vertical rod 32 is used to enhance the stability of the cross bar 31 and stir the compost material at the same time.

[0063] The horizontal bar 31 and the vertical bar 32 are both in a rhombus shape. This arrangement makes it easy for the horizontal bar 31 and the vertical bar 32 to cut into the compost material, thereby facilitating the stirring of the compost material.

[0064] During specific use, the motor 23 is started to drive the second gear 22 to rotate, and the second gear 22 rotates to drive the outer gear ring 2 to rotate. The outer gear ring 2 cooperates with the inner gear ring 24. During the rotation of the outer gear ring 2, the first gear 21 is driven to rotate around the outer gear ring 2, and the first gear 21 is caused to rotate on its own. When the first gear 21 rotates around the outer gear ring 2 and rotates on its own, the first rotating rod 3 is driven to rotate around the outer gear ring 2 and rotate on its own, so that the horizontal rod 31 and the vertical rod 32 rotate around the outer gear ring 2 and rotate on their own, thereby achieving the purpose of fully and evenly stirring the compost material, so that the compost material can be fully and evenly mixed with water, bacterial agent particles or dry matter.

The first rotating rod 3 is connected to the support plates 243 via bearings. The support ring 242 cooperates with the support plates 243 to support the first gear 21 and the first rotating rod 3.

[0067] A spreading box 4 is connected to the lower surface of the outer tooth ring 2 for evenly spreading bacterial agent particles or dry substances on the compost material.

[0068] A feed inlet 41 is provided above the material spreading box 4 , and the lower end of the first feed pipe 11 is located in the feed inlet 41 . The first feed pipe 11 can add bacterial agent particles or dry substances into the material spreading box 4 through the feed inlet 41 .

[0069] A plurality of evenly arranged partition plates 43 are connected to the material spreading box 4 for distributing the material spreading box 4 into a plurality of areas. After entering the material spreading box 4, the inoculant particles or dry matter will be divided into different areas, so that the inoculant particles or dry matter can be evenly spread on the compost material.

[0070] A conical material distribution column 44 is connected to the middle of the material spreading box 4, and a table-shaped groove block 112 is connected to the position corresponding to the material distribution column 44 below the first feeding pipe 11, which is used to concentrate the bacterial agent particles or dry matter so that the bacterial agent particles or dry matter can fall onto the material distribution column 44. Through the material distribution column 44, the bacterial agent particles or dry matter can be evenly distributed in each area of ​​the material spreading box 4.

[0071] Discharge ports 46 are respectively provided between the adjacent partition plates 43 of the spreading box 4 , and the bacterial agent particles or dry substances can fall onto the composting material through the discharge ports 46 .

[0072] A symmetrically arranged guide block 45 is connected to the position of the partition plate 43 corresponding to the discharge port 46 , and is used to guide the bacterial agent particles or dry matter to the discharge port 46 to prevent the bacterial agent particles or dry matter from accumulating in the spreading box 4 .

[0073] A discharge hole 42 is provided at the bottom of the material spreading box 4, through which some bacterial agent particles or dry substances can fall.

[0074] The bottom cross section of the spreading box 4 forms an angle of 3° with the horizontal plane. With this arrangement, the inoculant particles or dry matter can roll to the position of the discharge port 46 under the action of their own gravity and fall through the discharge port 46, and the inoculant particles or dry matter can be prevented from rolling too fast.

[0075] A symmetrically arranged connecting arm 5 is connected to the position of the discharge port 46 on the outside of the spreading box 4, a connecting rod 51 is connected between the connecting arms 5, and an L-shaped first receiving plate 52 is rotatably connected to the outside of the connecting rod 51 for receiving the inoculant particles or dry matter and spreading the inoculant particles or dry matter to a position between the periphery and the middle of the composting material.

[0076] Symmetrically arranged torsion springs 53 are connected between the two sides of the first receiving plate 52 and the connecting arm 5 for resetting the first receiving plate 52 .

[0077] A second receiving plate 54 is connected above the first receiving plate 52 and is used to receive the bacterial agent particles or dry matter and spread the bacterial agent particles or dry matter to the periphery of the composting material.

[0078] The second receiving plate 54 is connected to a symmetrically arranged baffle plate 55 on its upper surface for blocking the inoculant particles or dry matter to prevent the inoculant particles or dry matter from scattering from the second receiving plate 54 so that the inoculant particles or dry matter can accurately fall to the periphery of the composting material.

[0079] The first receiving plate 52 has an angle of 30° with the horizontal plane below, and the second receiving plate 54 has an angle of 33° with the horizontal plane. This arrangement ensures that the bacterial agent particles or dry matter fall into the first receiving plate 52. After a certain weight of bacterial agent particles or dry matter are stored in the first receiving plate 52, the first receiving plate 52 can be rotated. After the first receiving plate 52 rotates, the second receiving plate 54 is driven to rotate so that the second receiving plate 54 contacts the material spreading box 4, so that the first receiving plate 52 can have an angle of 3° with the horizontal plane, so that the bacterial agent particles or dry matter can fall.

[0080] In specific use, the inoculant particles or dry matter are added into the first feeding pipe 11 during the rotation of the outer gear ring 2. After the inoculant particles or dry matter contact the deceleration plate 111, the descending speed will be slowed down to avoid the accumulation of the inoculant particles or dry matter. After the inoculant particles or dry matter contact the table-shaped groove block 112, the inoculant particles or dry matter will fall in the center and fall onto the distribution column 44. The distribution column 44 evenly distributes the inoculant particles or dry matter to each area of ​​the spreading box 4. A part of the inoculant particles or dry matter will fall into the compost through the discharge hole 42.

After the bacterial agent particles or dry matter in the first receiving plate 52 reach a certain weight, the first receiving plate 52 will rotate. After the first receiving plate 52 rotates 33°, an angle of 3° will be formed between the first receiving plate 52 and the horizontal plane. Under the action of the angle and the gravity of the bacterial agent particles or dry matter themselves, the bacterial agent particles The particles or dry matter will fall and fall to a position between the periphery and the middle of the compost material. When the first receiving plate 52 rotates 33°, the second receiving plate 54 will synchronously rotate 33°. After the second receiving plate 54 rotates 33°, it will contact the spreading box 4. At this time, another part of the inoculum particles or dry matter will fall on the second receiving plate 54 and, through the cooperation of the baffle plate 55, the inoculum particles or dry matter will fall to a position outside the compost material. After the inoculum particles or dry matter in the first receiving plate 52 fall, the first receiving plate 52 will be equipped with a baffle plate 55 under the action of the torsion spring 53. The outer gear ring 2 rotates, thereby driving the spreading box 4 to rotate, so that the inoculant particles or dry matter will generate centrifugal force when they fall. Under the action of centrifugal force, the inoculant particles or dry matter will be evenly scattered on the upper surface of the compost material, so that the inoculant particles or dry matter can be evenly scattered, so that the inoculant particles or dry matter can be evenly mixed with the compost material, which can speed up the composting efficiency and improve the composting quality of the fertilizer.

[0082] A second rotating rod 62 is connected to the middle of the lower part of the spreading box 4. The lower part of the second rotating rod 62 is located in the upper barrel 6. An auger blade 63 is connected to the outer side of the second rotating rod 62 corresponding to the inner part of the upper barrel 6 for transporting the compost material at the lower part of the compost tank 1 to the upper part of the compost tank 1.

[0083] During specific use, the second rotating rod 62 and the auger blade 63 are driven to rotate during the rotation of the spreading box 4. The auger blade 63 transfers the compost material at the bottom of the compost tank 1 to the top of the compost tank 1 during the rotation, thereby achieving the purpose of spreading the bacterial agent particles, dry matter or water to different layers of the compost material, so that the bacterial agent particles, dry matter or water are fully and evenly mixed with the compost material, and the compost material will not be agglomerated, thereby ensuring the compost quality and compost efficiency.

[0084] The first rotating rod 3 is connected with symmetrically arranged fixing rings 7 between the second feeding pipe 13 and the upper end of the vertical rod 32, and a limiting ring 71 is arranged between the fixing rings 7. The first rotating rod 3 is rotatably connected in the limiting ring 71, and the fixing ring 7 is used to fix the position of the limiting ring 71.

[0085] A plurality of first scrapers 72 are connected to the position of the limiting ring 71 corresponding to the inner wall of the compost tank 1, and a plurality of second scrapers 73 are connected to the position of the limiting ring 71 corresponding to the outer side of the loading barrel 6. The first scrapers 72 are used to scrape off the compost material attached to the inner wall of the compost tank 1, and the second scrapers 73 are used to scrape off the compost material attached to the outer side of the loading barrel 6. The limiting ring 71 is used to limit the positions of the first scrapers 72 and the second scrapers 73, so that the first scrapers 72 always rotate around the inner wall of the compost tank 1, and the second scrapers 73 always rotate around the outer side of the loading barrel 6, thereby preventing the first scrapers 72 and the second scrapers 73 from shifting.

[0086] Working principle: start the motor 23 to rotate the first rotating rod 3, and the rotation of the first rotating rod 3 drives the horizontal rod 31, the vertical rod 32, the first scraper 72 and the second scraper 73 to rotate, and the chopped compost material is added into the compost tank 1 through the second feeding pipe 13. With the cooperation of the horizontal rod 31, the vertical rod 32, the first scraper 72 and the second scraper 73, the compost material can be broken up and evenly distributed in the compost tank 1. After the compost material is added, the bacterial agent particles are added into the first feeding pipe 11, and with the cooperation of the spreading box 4, the first receiving plate 52 and the second receiving plate 54, the bacterial agent particles are evenly spread on the upper surface of the compost material. With the cooperation of the horizontal rod 31, the vertical rod 32 and the auger blade 63, the bacterial agent particles can fall to different levels of the compost material and be fully and evenly mixed with the compost material. After the addition of the agent particles is completed, if the compost material has a lot of moisture, the dry matter is added into the first feed pipe 11 to make the dry matter and the compost material fully and evenly mixed, thereby reducing the moisture of the compost material. If the compost material is relatively dry, the water inlet pipe 17 is opened, and the compost material can be fully and evenly mixed with water under the cooperation of the annular water pipe 15, the atomizing nozzle 16, the cross bar 31, the vertical rod 32 and the auger blade 63. After the compost material is prepared, it can be left to ferment. After the fermentation is completed, fertilizer is formed. The discharge pipe 18 is opened through the valve 19, and the motor 23 is turned on. The fertilizer will be broken up by the cooperation of the cross bar 31 and the vertical rod 32, so that the fertilizer is easier to fall. After most of the fertilizer falls, the motor 23 is reversed to remove the fertilizer in the upper barrel 6, so that no fertilizer will remain in the compost tank 1.
