[0019] A composting method of a vegetable waste composting device comprises the following steps:

[0020] S1: First, add the vegetable waste and active organic fertilizer into the compost barrel through the feeding pipe, and drive the rotating shaft to rotate through the servo motor, so that it drives the fixed part to rotate, and the fixed part drives the first block to rotate, so that the first block and the second block are against each other, so that the bottom plate rotates, thereby ensuring that the vegetable waste and active organic fertilizer can be evenly spread in the compost barrel. After the feeding is completed, the feeding pipe can be sealed;

[0021] S2: When stirring the waste vegetable materials in the compost barrel, the servo motor will drive the shaft to reverse, so that the shaft drives the stirring rod to rotate to achieve the stirring effect. At the same time, the shaft will use the transmission component to drive the disc to rotate when rotating, and the disc will drive the ventilation mechanism to work when rotating. On the one hand, the ventilation mechanism will introduce fresh air from the outside into the compost barrel to provide the necessary oxygen environment for the microbial activities during the composting process. On the other hand, the ventilation mechanism is also responsible for collecting the gas generated in the compost barrel and transporting these gases to the tail gas treatment device for purification to ensure the safety and hygiene of the environment;

[0022] S3: When the shaft rotates in the opposite direction, the first block under the fixing part will slide against the surface of the second block, thereby squeezing the second block, and the second block will push the bottom plate to move upward, so that the bottom plate drives the waste vegetable materials in the compost barrel to move upward. When the first block and the second block are offset, the bottom plate is reset, causing the waste vegetable materials on the bottom plate to vibrate, which is helpful to further mix and loosen the waste vegetable materials, thereby improving the uniformity and efficiency of the composting process. Through the setting of the filter holes, the accumulated liquid generated during composting can penetrate to the bottom of the bottom plate and be discharged from the drain port.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the vegetable waste composting device and composting method can vibrate the waste vegetable materials in the composting barrel while stirring, thereby promoting the loosening and mixing uniformity of the waste vegetable materials, and at the same time, fresh air can be introduced into the composting barrel to provide a sufficient oxygen environment for the microbial activities in the composting process, promote the rapid decomposition of organic matter, and introduce the gas generated during the decomposition into the tail gas treatment device for purification treatment. The specific contents are as follows:

[0024] 1. A first resistance block and a second resistance block are provided. When adding vegetable waste and active organic fertilizer, the first resistance block will rotate synchronously driven by the rotating shaft, so that the first resistance block and the second resistance block are resisted, thereby driving the bottom plate to rotate, so that the fallen vegetable waste and active organic fertilizer can be evenly spread on the bottom plate, thereby improving the composting efficiency. During stirring, the first resistance block will rotate along the direction of the rotating shaft, thereby moving along the surface of the second resistance block. Since the first resistance block is a right-angled triangle structure, it will squeeze the second resistance block when rotating, so that the second resistance block drives the bottom plate to move up and down, thereby generating vibration, which is helpful to break the agglomeration and agglomeration between the waste vegetable raw materials, so that the vegetable waste and the active organic fertilizer can be more fully mixed during the stirring process, thereby improving the mixing uniformity.

[0025] 2. A tooth block and a tooth groove are provided. When the rotating shaft rotates in the opposite direction, the rotating shaft will drive the tooth block to rotate synchronously. At this time, the tooth block will resist the inner wall of the tooth groove under the action of the elastic force of the auxiliary spring, thereby driving the disc to rotate. When the disc rotates, it will drive the belt to rotate, so that the belt drives the reciprocating screw to rotate, and the reciprocating screw will engage and drive the first support plate to move downward, thereby driving the connecting rod, the second support plate, the bracket and the nozzle to move downward synchronously through the first support plate, so that the nozzle is inserted into the tail vegetable raw material. At this time, the rotation of the disc drives the fixed column to rotate, so that the fixed column slides in the slide groove, thereby pushing the moving part to move, and the moving part will push the connecting rod to move, so that the connecting rod pushes the piston rod to move, and the piston rod will push the piston piece to move, thereby delivering the fresh air stored in the first piston cylinder to the nozzle, and then sprayed into the tail vegetable raw material by the nozzle. As the nozzle gradually moves downward, the fresh air is fully injected into the deeper tail vegetable raw material, providing the necessary oxygen environment for the aerobic microorganisms in the compost, thereby accelerating the metabolic activity of the microorganisms and improving the decomposition efficiency of organic matter.

In the existing process of adding materials, the raw materials will fall below the drop opening, and it is necessary to manually spread the raw materials in the composting box, which increases the workload of the workers.

The fixed member 7 is fixedly connected, and a plurality of first resist blocks 8 at the upper end of the fixed member 7 are arranged in a circular array about the center point of the fixed member 7, and the first resist blocks 8 are arranged in a right triangle structure. A drain port 202 is opened on the side wall of the compost bucket 2, and the drain port 202 is located below the bottom plate 9. The bottom plate 9 is slidably arranged at the bottom end of the compost bucket 2, and the bottom plate 9 is slidably connected to the rotating shaft 6.

[0042] In this technical solution, Figure 2 As shown, the present technical solution utilizes the setting of the first block 8 and the second block 11, so that the rotating shaft 6 will drive the first block 8 to rotate when it rotates, thereby pushing the second block 11 through the first block 8, and utilizing the second block 11 to drive the bottom plate 9 to rotate, so that the added tail vegetable materials can be evenly spread on the bottom plate 9, which helps to accelerate the decomposition of microorganisms and improve the composting efficiency.

[0043] Its use is as Figure 5 The technical solution shown in the figure, first turn on the servo motor 5, the servo motor 5 will drive the rotating shaft 6 to rotate forward, the rotating shaft 6 will drive the fixing member 7 to rotate when rotating, the fixing member 7 will drive the first resisting block 8 to rotate, then the first resisting block 8 will resist the second resisting block 11, thereby pushing the second resisting block 11, and the second resisting block 11 drives the bottom plate 9 to rotate along the inner wall of the compost bucket 2, at this time, the tail vegetable raw materials are added from the first feeding pipe 201, the tail vegetable raw materials will fall onto the bottom plate 9 under the action of gravity, and then as the bottom plate 9 continues to rotate, the first resisting block 8 will resist the second resisting block 11, thereby pushing the second resisting block 11, and the second resisting block 11 will drive the bottom plate 9 to rotate along the inner wall of the compost bucket 2. The bottom plate 9 aligned with the first feeding tube 201 will be aligned with the second feeding tube 201. At this time, active organic fertilizer is added, causing the active organic fertilizer to fall to the upper end of the waste vegetable raw materials. Then the bottom plate 9 will continue to rotate, causing the bottom plate 9 aligned with the second feeding tube 201 to be re-aligned with the first feeding tube 201. At this time, new waste vegetable raw materials will fall to the upper end of the active organic fertilizer, and so on and so forth, thereby realizing the alternating addition of waste vegetable raw materials and active organic fertilizer, forming a clear hierarchical structure in the composting process, thereby improving the quality of the compost.

[0046] Its use is as Figure 1 and Figure 3-Figure 6 The technical solution shown in the figure, first, when the waste vegetable raw materials in the compost bucket 2 are stirred, the servo motor 5 will drive the rotating shaft 6 to reverse, and the rotating shaft 6 will drive the stirring rod 12 to rotate when rotating, so that the waste vegetable raw materials are stirred by the stirring rod 12, and the fixing member 7 will be synchronously reversed with the rotating shaft 6, and drive the first stop block 8 to rotate. Since the first stop block 8 is set as a right-angled triangle, the inclined surface at the bottom end of the first stop block 8 slides against the surface of the second stop block 11, so that the first stop block 8 pushes the second stop block 11, so that the second stop block 11 drives the bottom plate 9 to move upward, and after the first stop block 8 is separated from the second stop block 11, the bottom plate 9 is reset under the action of the waste vegetable raw materials, and so on and so forth, so that the waste vegetable raw materials vibrate up and down when stirring, thereby improving the stirring efficiency;

[0047] Since the shaft 6 and the disk 14 are connected via the transmission assembly 15, when the shaft 6 rotates forward, the shaft 6 drives the tooth block 1501 to rotate, and one side of the tooth block 1501 slides in contact with the tooth groove 1502, thereby causing the tooth block 1501 to rotate and squeeze the auxiliary spring 1503 to contract. At this time, the disk 14 does not rotate. When the shaft 6 rotates reversely, the tooth block 1501 fits with the other side of the tooth groove 1502 under the action of the elastic force of the auxiliary spring 1503, thereby driving the disk 14 to rotate synchronously. The disk 14 drives the fixed column 1301 to rotate, so that the fixed column 1301 slides along the slide groove 1303 while pushing the moving member 1302 to reciprocate. When the moving member 1302 moves, it pushes the connecting rod 1304 to move, and the connecting rod 1304 drives the piston rod 1305 to move, so that the piston rod 1305 pulls the piston plate 1308 to move.

[0048] The disc 14 will drive the belt 16 to rotate while rotating, thereby driving the two reciprocating screws 17 to rotate through the belt 16, and the reciprocating screw 17 will mesh and drive the first support plate 1310 to move. When the first support plate 1310 moves downward, the first support plate 1310 will drive the connecting rod 1311 to move, and the connecting rod 1311 will drive the second support plate 1312 to move, thereby driving the rotating ring 1316 and the moving tube 1317 to move synchronously through the second support plate 1312, and the moving tube 1317 will drive the bracket 1318 to move, thereby pushing the nozzle 1319 to be inserted into the tail vegetable raw material through the bracket 1318, and at this time, the piston rod 1305 will push the piston piece 1308 to move in the first piston cylinder 1306 and the second piston cylinder 1307. The piston cylinder 1306 is connected to the connecting sleeve 1322 through a one-way flow pipe, so that air is transported into the connecting sleeve 1322, and then transported into the nozzle 1319 through the ventilation channel 18, and finally ejected from the nozzle 1319. As the nozzle 1319 gradually extends, the air will be injected into the tail vegetable raw materials in a deeper layer. When the first stop block 8 is reset and moved, the nozzle 1319 will move away from the tail vegetable raw materials, and the piston piece 1308 in the first piston cylinder 1306 will move in the opposite direction, thereby sucking the external air, and the second piston cylinder 1307 will suck the gas generated by decomposition in the compost barrel 2 when the nozzle 1319 moves upward, and transport the gas generated by decomposition to the tail gas treatment device 3 for treatment when the nozzle 1319 moves downward;

[0049] When the first support plate 1310 is reset and moved, the connecting sleeve 1322 will fit with the inner wall of the top of the compost bucket 2, thereby squeezing the top rod 1321, so that the top rod 1321 squeezes the moving tube 1317, and the moving tube 1317 slides downward along the inner wall of the sleeve 1314 while squeezing the compression spring 1320, thereby driving the cross bar 1323 to move through the moving tube 1317, and the cross bar 1323 at this time will fit with the arc groove 1315 of the lower sleeve 1314 and slide along the arc groove 1315, thereby driving the moving tube 1317 to rotate, and the moving tube 1317 will drive the rotating ring 1316 to rotate. When the plate 1310 moves downward, the compression spring 1320 will gradually reset, thereby pushing the moving tube 1317 to reset. The moving tube 1317 will drive the cross bar 1323 to move upward, so that the cross bar 1323 fits with the arc groove 1315 of the upper sleeve 1314 and slides along the arc groove 1315, thereby causing the moving tube 1317 to rotate once. When the moving tube 1317 rotates, it will drive the top rod 1321 to rotate along the inner wall of the connecting sleeve 1322. At the same time, the bracket 1318 and the nozzle 1319 will rotate synchronously to adjust the position of the nozzle 1319, thereby ensuring that air can fully penetrate into the tail vegetable raw materials.

[0050] A composting method of a vegetable waste composting device comprises the following steps:

[0051] S1: First, add the vegetable waste and active organic fertilizer into the compost barrel 2 through the feeding pipe 201, and drive the rotating shaft 6 to rotate through the servo motor 5, so that it drives the fixing member 7 to rotate, and the fixing member 7 drives the first stop block 8 to rotate, so that the first stop block 8 and the second stop block 11 are abutted, so that the bottom plate 9 rotates, thereby ensuring that the vegetable waste and active organic fertilizer can be evenly spread in the compost barrel 2. After the feeding is completed, the feeding pipe 201 is capped;

[0052] S2: When stirring the waste vegetable materials in the compost barrel 2, the servo motor 5 drives the rotating shaft 6 to reverse, so that the rotating shaft 6 drives the stirring rod 12 to rotate, so as to achieve the stirring effect. At the same time, the rotating shaft 6 drives the disc 14 to rotate by means of the transmission assembly 15 when rotating, and the disc 14 drives the ventilation mechanism 13 to work when rotating. On the one hand, the ventilation mechanism 13 introduces fresh air from the outside into the compost barrel 2 to provide the necessary oxygen environment for the microbial activities during the composting process. On the other hand, the ventilation mechanism 13 is also responsible for collecting the gas generated in the compost barrel 2 and transporting the gas to the tail gas treatment device 3 for purification treatment to ensure the safety and sanitation of the environment.

[0053] S3: When the rotating shaft 6 rotates in the opposite direction, the first stop block 8 under the fixing member 7 will slide against the surface of the second stop block 11, thereby squeezing the second stop block 11, and the second stop block 11 will push the bottom plate 9 to move upward, so that the bottom plate 9 drives the waste vegetable materials in the composting bucket 2 to move upward. When the first stop block 8 and the second stop block 11 are staggered, the bottom plate 9 is reset, so that the waste vegetable materials on the bottom plate 9 vibrate, which is helpful to further mix and loosen the waste vegetable materials, and improve the uniformity and efficiency of the composting process. Through the setting of the filter hole 10, the accumulated liquid generated during composting can penetrate to the bottom of the bottom plate 9 and be discharged from the drain port 202.
