Technical Field

[0001] The invention relates to a compost fermentation device with linked turning and aeration and a use method, belonging to the field of composting equipment. Background Art

[0002] When using a fermentation tank for composting, the raw materials inside the tank need to be stirred to ensure uniform oxygen distribution, promote microbial activity, regulate temperature and humidity, and accelerate material homogenization and fermentation process. Currently, the common composting tanks on the market are mostly stirred by horizontally set stirring rods. Since they can only stir in the horizontal direction, it is usually necessary to set up multiple sets of stirring rods. However, since the material cannot be stirred in the vertical direction inside the tank, the homogenization and fermentation efficiency of the material are affected. Therefore, it is necessary to improve them. Summary of the Invention

[0006] A method for using a compost fermentation device with linked turning and aeration, the method comprising the following steps:

[0007] Step 1: Put the raw materials into the tank from the feed port and start the motor;

[0008] Step 2: The motor drives gear I and the drum to rotate, and the drum drives the stirring rod to rotate to stir the raw materials;

[0009] Step 3: When the stirring rod drives the telescopic rod and the fixed block to move to the position where the annular groove is farthest from the center of the limit plate, the stirring rod opens at the maximum angle and the slide moves to the highest point;

[0010] Step 4: When the stirring rod drives the telescopic rod and the fixed block to move to the position where the annular groove is closest to the center of the limit plate, the angle of the stirring rod is the smallest and the slide moves to the lowest point;

[0011] Step 5: Air is pumped into the airway via an air pump to actively aerate the raw materials within the tank. Compared to existing technologies, the present invention offers the following advantages: The device utilizes two interactively positioned stirring rods, which, when opened at different angles, achieve different stirring positions, effectively ensuring a stirring effect and accelerating material homogenization and fermentation.

[0029] The annular groove 212 is not concentric with the hole 211 .

[0031] An air passage 112 is provided at the center of the round rod 111 , and an air pipe 114 communicating with the air passage 112 is fixedly connected to the bottom of the side of the round rod 111 ; an air hole 115 is provided at the upper end of the air pipe 114 .

[0032] A method for using a compost fermentation device with linked turning and aeration, the method comprising the following steps:

[0033] Step 1: Put the raw materials into the tank 11 from the feed port 13 and start the motor 17;

[0034] Step 2: The motor 17 drives the gear I 14 and the drum 15 to rotate, and the drum 15 drives the stirring rod 24 to rotate to stir the raw materials;

[0035] Step 3: When the stirring rod 24 drives the telescopic rod 23 and the fixed block 22 to move to the position where the annular groove 212 is farthest from the center of the limit plate 21, the stirring rod 24 opens at the maximum angle and the slide plate 25 moves to the highest point;

[0036] Step 4: When the stirring rod 24 drives the telescopic rod 23 and the fixed block 22 to move to the position where the annular groove 212 is closest to the center of the limit plate 21, the angle of the stirring rod 24 is the smallest, and the slide plate 25 moves to the lowest point;

[0037] Step 5: Air is pumped into the air passage 112 through an air pump to actively aerate the raw materials inside the tank body 11 .

[0038] The working principle of the present invention is as follows: when using the device, raw materials are put into the tank body 11 from the feed port 13 and the motor 17 is started;

[0039] The motor 17 drives the gear II 18 to rotate, which in turn drives the gear I 14 and the drum 15 to rotate, and the drum 15 drives the stirring rod 24 to rotate to stir the raw materials; during the rotation of the stirring rod 24, the stirring rod 24 drives the telescopic cylinder 23 to rotate, and the telescopic cylinder 23 drives the fixed block 22 to rotate in the annular groove 212. When the fixed block 22 moves to the position where the annular groove 212 is farthest from the center of the limit plate 21, the telescopic cylinder 23 contracts and the stirring rod 24 opens at the maximum angle. When the fixed block 22 moves to the position where the annular groove 212 is closest to the center of the limit plate 21, the telescopic cylinder 23 stretches and the stirring rod 24 opens at the minimum angle, so that the stirring rod 24 will also rotate around the hinge at the connection with the drum 15 during the rotation of the stirring rod 24, so that the stirring range of the free end of the stirring rod 24 is increased, so that the material at the bottom of the tank body 11 can be fully stirred;

[0040] When the stirring rod 24 drives the telescopic rod 23 and the fixed block 22 to move to the position where the annular groove 212 is farthest from the center of the limit plate 21, the stirring rod 24 opens at the maximum angle and the slide 25 moves to the highest point; when the stirring rod 24 moves from the minimum opening angle to the maximum opening angle position (that is, the free end of the stirring rod 24 moves from the position closest to the round rod 111 to the position farthest from the round rod 111), the stirring rod 24 with the slide 28 moves in the direction away from the round rod 111, and the slider II 273 pulls the stirring rod 24 to the maximum opening angle position. The multi-stage telescopic rod 271 slides in the connecting hole II 253. Since the multiple slide cylinders of the multi-stage telescopic rod 271 have an interference fit, the length of the multi-stage telescopic rod 271 remains unchanged. After the slide cylinder with the largest diameter of the multi-stage telescopic rod 271 first leaves the slide groove II 113, the limit block II 272 moves to contact the inner wall of the limit groove II 254. At this time, the slide cylinder with the largest diameter no longer moves, and the other slide cylinders are stretched. At the same time, when the stirring rod 24 moves in the direction away from the round rod 111, it also pushes the slider I 264 to move, and the slider I 264 pushes The connecting rod 262 moves. Since the connecting rod 262 and the limiting rod 261 have an interference fit, the connecting rod 262 pushes the limiting rod 261 to be inserted into the chute Ⅰ 12. After the limiting rod 261 is inserted into the bottom of the chute Ⅰ 12, the limiting rod 261 can no longer move relative to the chute Ⅰ 12. At this time, the stirring rod 24 continues to move to push the connecting rod 262 to be inserted into the limiting rod 261. As the stirring rod 24 rotates, the stirring rod 24 drives the slide plate 25 to rotate with the stirring rod 24 through the chute III 252. Since the limiting rod 261 is inserted into the bottom of the chute Ⅰ 12, the limiting rod 261 can no longer move relative to the chute Ⅰ 12. As the slide 25 rotates, the limit rod 261 moves along the setting direction of the slide 112, thereby causing the slide 25 to move upward in the vertical direction, so that the material on the upper end of the slide 25 is also pushed upward, leaving a gap at the lower end of the slide 25 after the slide 25 moves. Under the push of the stirring rod 24, the material around the slide 25 will fill the gap below the slide 25 under the action of gravity, thereby causing the material in the middle and upper part of the tank body 11 to move to the center of the tank body 11, ensuring the stirring effect. Until the slide 25 moves to the highest point, it reaches the state as shown in the figure. Figure 1 、 4 Status shown.

[0041] When the stirring rod 24 drives the telescopic rod 23 and the fixed block 22 to move to the position where the annular groove 212 is closest to the center of the limit plate 21, the angle of the stirring rod 24 is minimized, and the slide plate 25 moves to the lowest point; when the stirring rod 24 moves from the maximum opening angle to the minimum opening angle position (that is, the free end of the stirring rod 24 moves from the position farthest from the round rod 111 to the position closest to the round rod 111), the free end of the stirring rod 24 with the slide 28 moves in the direction close to the round rod 111, and when the stirring rod 24 moves in the direction close to the round rod 111, the connecting rod 262 is driven to move by the slider I 264. The connecting rod 262 and the limit rod 261 have an interference fit, so that the limit rod 261 is directly driven to move, so that the limit rod 261 is disengaged from the slide groove I 12. At the same time, the stirring rod 24 pushes the multi-stage telescopic rod 271 to move through the slider II 273. The multiple slide cylinders on the multi-stage telescopic rod 271 have an interference fit. This drives the slide with the largest diameter of the multi-stage telescopic rod 271 into chute II 113 until it reaches the bottom of chute II 113. When the stirring rod 24 moves further, it pushes the multi-stage telescopic rod 271 to retract. As the stirring rod 24 rotates, the stirring rod 24 drives the slide plate 25 to rotate along with the stirring rod 24 through the chute III 252. Since the multi-stage telescopic rod 271 is inserted into chute II 113, as the slide plate 25 rotates, the limit rod 261 moves along the direction of the chute II 113, causing the slide plate 25 to move downward in the vertical direction. The material at the lower end of the slide plate 25 is squeezed to the sides of the slide plate 25, leaving a gap at the upper end after the slide plate 25 moves. Under the push of the stirring rod 24, the material around the slide plate 25 fills the gap above the slide plate 25 under the action of gravity, thereby moving the material in the upper middle portion of the tank body 11 to the center of the tank body 11, ensuring the stirring effect. The above process is repeated until the slide plate 25 reaches its lowest point.

[0042] Air is pumped into the air passage 112 through an air pump, enters the air pipe 114 , and enters the tank body 11 through the air holes 115 , actively aerating the raw materials inside the tank body 11 .
