Description

Technical Field

[0001] The invention relates to an aeration device for composting, and in particular to a static composting aeration and loosening device and a use method thereof. Background Art

[0002] Static composting is a simple composting method that involves piling prepared materials into long strips approximately two meters high, or other shapes depending on site conditions. Similar to open composting, this method often involves composting under pressure, preventing outside air from reaching the interior. This results in an anaerobic state, a strong odor, incomplete fermentation, and a long fermentation cycle. To improve the efficiency and quality of static composting, aeration can be used to add air to the compost, loosening the compost and improving oxygen distribution and uniformity.

[0003] Existing manual aeration devices primarily utilize a cylindrical structure, inserted into the location to be aerated, and injecting high-pressure air for loosening. For example, Chinese invention patent publication number CN104704949B discloses a soil loosening device based on airflow. The device comprises an airflow injection device that can be inserted into the soil for injecting a burst of airflow into the soil, and an airflow accelerator for accelerating the input high-pressure airflow. The airflow accelerator is connected to the input port of the airflow injection device, and the airflow accelerator is a venturi tube. The airflow injection device includes a cylindrical loosening head. This cylindrical soil loosening device has the disadvantage of a small loosening range per time.

[0004] The existing automatic aeration device pre-buries an aeration passage at the bottom of the composting tank, which easily leads to the aeration passage being blocked. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a static composting aeration and loosening device and a use method, which adopts a claw-shaped aeration head that can open and close, so that the aeration range can be wider at one time and the aeration uniformity is better.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A static composting aeration and loosening device comprises a main movement component and an airflow component;

[0008] The main motion assembly includes a sleeve rod, a support rod, an aeration head and a connecting rod. The support rod is slidably arranged in the inner hole of the sleeve rod. The aeration head includes at least three aeration claws. The upper ends of the aeration claws are rotatably connected to the lower ends of the support rods. The number of the connecting rods is the same as the number of the aeration claws. The upper end of one of the connecting rods is rotatably connected to the lower end of the sleeve rod, and the lower end is rotatably connected to the outer side of the middle section of one of the aeration claws. The at least three aeration claws are truncated cone-shaped when the lower ends are closed, and are claw-shaped when the lower ends are opened.

[0009] The airflow assembly includes a vent hole located in the middle of the support rod, connecting the upper and lower ends; a primary venturi tube installed in the vent hole; a main aeration hole located on the aeration claw; a hose connecting the lower end of the vent hole to the upper end of the main aeration hole; and side aeration holes on the aeration claw that connect to the main aeration hole. The claw-shaped aeration head provides aeration, providing a wide aeration range and good aeration uniformity.

[0010] The method for using the static composting aeration and loosening pile device in the above paragraph is as follows:

[0011] Initially, at least three aeration claws of the aeration head are closed to form a truncated cone-shaped aeration head, and the aeration head extends into the static compost;

[0012] The support rod slides downward relative to the sleeve rod, and under the action of the connecting rod, at least three aeration claws of the aeration head slowly open until the aeration claws are in an open claw shape;

[0013] Ventilating air into the airflow assembly for aeration;

[0014] After aeration is completed, the support rod slides upward relative to the sleeve, and at least three aeration claws of the aeration head slowly close until the aeration head closes into a truncated cone shape, and the aeration head is pulled out of the static compost.

[0015] The beneficial effect is that the aeration operation range and uniformity are improved by opening the claw-shaped aeration head.

[0016] Furthermore, the aeration head further includes an aeration core rod vertically disposed at its center, the aeration core rod also being provided with the main aeration hole and side aeration holes connected to the main aeration hole, the upper end of the main aeration hole of the aeration core rod being connected to the lower end of the vent hole, thereby further improving the aeration range and uniformity.

[0017] Furthermore, the airflow assembly further includes a secondary venturi tube, which is arranged between the vent hole and the main aeration hole to further increase the aeration pressure.

[0018] Furthermore, it also includes a bayonet pin assembly, which includes a latch seat, a first spring, a latch, a latch nut and a second spring. The latch seat is sleeved on the outside of the sleeve rod. The side wall of the sleeve rod is provided with a sliding groove arranged up and down. A slider extends from the inner side surface of the latch seat. The slider extends into the sliding groove and slides up and down. The inner end of the slider is fixedly connected to the support rod. The first spring is sleeved on the support rod and is located between the latch seat and the sleeve rod.

[0019] A latch hole is formed on a side of the latch seat, the latch pin slides horizontally into the latch hole, the latch nut is locked on the outer side of the latch hole, the second spring is sleeved on the latch pin and is located in the latch hole, and under the action of the second spring, the inner end of the latch pin extends out of the latch hole;

[0020] The inner end of the latch is provided with a tenon, and the lower side wall of the sleeve rod is provided with a slot. When the tenon of the latch is engaged with the slot of the sleeve rod, the aeration claw of the aeration head is in an open state. When the tenon of the latch is disengaged from the slot of the sleeve rod, the aeration claw of the aeration head is in a closed state under the action of the first spring. The engagement of the tenon and the slot ensures that the claw-type aeration head has good structural stability during aeration.

[0021] The method for using the static composting aeration and loosening pile device in the above paragraph is as follows:

[0022] Initially, at least three aeration claws of the aeration head are closed to form a truncated cone-shaped aeration head, and the aeration head extends into the static compost;

[0023] The support rod slides downward relative to the sleeve rod, driving the latch assembly to slide downward together. Under the action of the connecting rod, at least three aeration claws of the aeration head slowly open until the tenon of the latch is stuck in the slot of the sleeve rod, and the aeration claws are in an open claw shape;

[0024] Ventilating air into the airflow assembly for aeration;

[0025] After aeration is completed, the tenon of the latch is disengaged from the slot of the sleeve rod. Under the action of the first spring, the support rod slides upward relative to the sleeve, and at least three aeration claws of the aeration head slowly close until the aeration head closes in a truncated cone shape, and the aeration head is pulled out of the static compost.

[0026] The beneficial effect is that during aeration, the bayonet assembly is added to improve the structural stability of the device during aeration.

[0027] Furthermore, the latch assembly also includes an annular triangular ring that slides up and down within the slot. The slot is wider than the width of the triangular ring. The cross-section of the tenon is a right triangle with a horizontal upper surface and an acute angle facing the slot. The upper surface of the triangular ring is tilted downward and the lower surface is tilted upward. The tilt direction of the upper surface of the triangular ring is consistent with the tilt direction of the lower surface of the latch, and the upper surface of the slot is consistent with the tilt direction of the upper surface of the triangular ring. The use of the triangular ring allows the tenon to be disengaged from the slot by mechanically pressing down on the latch seat, that is, mechanically releasing the latch connection with the slot, facilitating subsequent manual or automatic operation.

[0028] The method for using the static composting aeration and loosening pile device in the above paragraph is as follows:

[0029] Initially, the triangular ring is in contact with the lower surface of the slot under the action of its own gravity, and at least three aeration claws of the aeration head are closed to form a truncated cone-shaped aeration head, and the aeration head extends into the static compost;

[0030] The support rod slides downward relative to the sleeve rod, driving the bayonet assembly to slide downward together. Under the action of the connecting rod, at least three aeration claws of the aeration head slowly open until the tenon of the latch is stuck below the upper surface of the slot of the sleeve rod, and the aeration claws are in an open claw shape;

[0031] Ventilating air into the airflow assembly for aeration;

[0032] After aeration is completed, continue to apply downward force to make the support rod and sleeve rod slide downward. When the tenon touches the upper surface of the triangular ring, the tenon moves into the pin hole and immediately extends to the lower surface of the triangular ring. At this time, stop applying downward force to the support rod and sleeve rod. Under the action of the first spring, the support rod and sleeve rod slide upward, and the tenon drives the triangular ring to move upward until it fits with the upper surface of the slot. Under the action of the inclined lower surface of the triangular ring, the tenon moves into the pin hole again. At this time, the tenon of the pin is disengaged from the slot of the sleeve rod and continues to slide upward. At least three aeration claws of the aeration head slowly close until the aeration head closes in a truncated cone shape, and the aeration head is pulled out of the static compost.

[0033] The beneficial effect is that the triangular ring that can slide up and down can release the clamping connection between the tenon and the slot by simply pressing down, which is convenient to operate.

[0034] Furthermore, a first handle extending to the left and right is provided at the upper end of the sleeve rod, and a second handle extending to the left and right is provided at the upper end of the support rod. The first handle and the second handle are provided at the top of the longer sleeve rod and the support rod, respectively, so that a person can stand and use the loosening device, which is convenient for operation.

[0035] Furthermore, it also includes a power assembly, which includes a first telescopic power member, a second telescopic power member, a gantry, a first cross bar and a second cross bar, wherein the first telescopic power member is vertically fixed to the gantry, the second telescopic power member is vertically fixed to the output end of the first telescopic power member, the first cross bar is horizontally fixed to the telescopic end of the first telescopic power member, and the second cross bar is horizontally fixed to the telescopic end of the second telescopic power member;

[0036] The paired sleeve rods, support rods, and aeration heads are provided in a plurality and arranged side by side. The upper end of each sleeve rod is fixed to the first crossbar, and the upper end of each support rod is fixed to the second crossbar. Static compost is aerated and loosened using an automatic operation method, thereby improving operation efficiency.

[0037] The beneficial effects of the present invention are:

[0038] 1. By opening the claw-shaped aeration head, the aeration range and aeration uniformity of a single acupuncture point are increased, and the aeration claws can be closed into a truncated cone shape, so as not to affect the aeration head from extending into or withdrawing from static compost;

[0039] 2. Improve the structural stability of the aeration process through the bayonet assembly;

[0040] 3. The connection between the tenon and the sleeve rod slot in the bayonet assembly can be released by simply pressing down the latch seat. It can be operated purely mechanically or electrically. It has an ingenious structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0065] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , the embodiment 1 provided by the present invention is:

[0066] A static composting aeration and loosening device comprises a main movement component 1 and an airflow component 2;

[0067] The main motion assembly 1 includes a sleeve rod 11, a support rod 12, an aeration head 13 and a connecting rod 14. The support rod 12 is slidably arranged in the inner hole of the sleeve rod 11. The aeration head 13 includes at least three aeration claws 131. The upper ends of the aeration claws 131 are rotatably connected to the lower ends of the support rod 12. The number of the connecting rods 14 is consistent with the number of the aeration claws 131. The upper end of one connecting rod 14 is rotatably connected to the lower end of the sleeve rod 11, and the lower end is rotatably connected to the outer side of the middle section of one aeration claw 131. At least three of the aeration claws 131 are in a frustum shape when the lower ends are closed, and in a claw shape when the lower ends are opened. The connecting rod 14 and slider 311 mechanism, comprised of the sleeve rod 11, support rod 12, connecting rod 14, and aeration claws 131, enables the aeration claws 131 to open and close outward. When at least three aeration claws 131 are closed into a truncated cone shape, they can be placed vertically for easy insertion into static compost. When at least three aeration claws 131 are opened into a claw-like shape, aeration can be performed over a wide area.

[0068] The airflow assembly 2 includes an air vent 21 disposed in the middle of the support rod 12, connecting the upper and lower portions thereof; a primary venturi tube 22 mounted within the air vent 21; a main aeration hole 23 disposed on the aeration claw 131; a hose 25 connecting the lower end of the air vent 21 with the upper end of the main aeration hole 23; and side aeration holes 24 on the aeration claw 131 that communicate with the main aeration hole 23. The primary venturi tube 22 is used to increase aeration pressure, and a hose 25 is provided between the air vent 21 of the support rod 12 and the main aeration hole 23 of the aeration claw 131 to facilitate the opening and closing of the aeration claw 131. The main aeration hole 23 is disposed along the length of the aeration claw 131, while the side aeration holes 24 communicate with the main aeration hole 23 and extend to the side of the aeration claw 131. When at least three aeration claws 131 are opened into claw shapes, the aeration claws 131 are evenly distributed with side aeration holes 24 on the sides thereof, so that the aeration claws 131 can aerate a wider range and the aeration uniformity in the operating range is also better.

[0069] Specifically, the number of the aeration claws 131 on the aeration head 13 is three, four, five or six.

[0070] Specifically, when the aeration claws 131 are opened, multiple side aeration holes 24 are arranged side by side and equidistantly above the main aeration holes 23, and multiple side aeration holes 24 are arranged side by side and equidistantly below the main aeration holes 23, so that aeration can be carried out above and below the aeration claws 131.

[0071] Specifically, with regard to the rotational connection method at both ends of the connecting rod 14, a first ear plate 111 is provided at the lower end of the sleeve rod 11, and the upper end of the connecting rod 14 is rotationally connected to the first ear plate 111 through a first pin shaft, and a second ear plate 132 is provided on the outer side of the middle section of the aeration claw 131, and the lower end of the connecting rod 14 is rotationally connected to the second ear plate 132 through a second pin shaft.

[0072] like Figure 10 As shown, the method of using the static composting aeration and loosening device is as follows:

[0073] Initially, at least three aeration claws 131 of the aeration head 13 are closed to form a truncated cone-shaped aeration head 13, and the aeration head 13 extends into the static compost;

[0074] The support rod 12 slides downward relative to the sleeve rod 11, and under the action of the connecting rod 14, at least three aeration claws 131 of the aeration head 13 slowly open until the aeration claws 131 are in an open claw shape;

[0075] Ventilate the airflow assembly 2 for aeration; during aeration, the gas entering the primary venturi tube 22 flows into the vent hole 21 of the support rod 12, then flows through the hose 25 to the main aeration hole 23 of the aeration claw 131, and flows out through the side aeration holes 24 of the aeration claw 131, thereby aerating and loosening the static compost;

[0076] After aeration is completed, the support rod 12 slides upward relative to the sleeve, and at least three aeration claws 131 of the aeration head 13 slowly close until the aeration head 13 closes into a truncated cone shape, and the aeration head 13 is pulled out of the static compost.

[0077] Since static compost has a certain degree of looseness, the truncated cone aeration head 13 can also be easily inserted into the static compost. Figure 5 and Figure 6 Of course, in order to reduce the resistance of the aeration head 13 entering the static compost, a conical tip can be added to the bottom of the aeration head 13, as shown. Figure 1 and Figure 2 shown.

[0078] When the aeration head 13 is opened into a claw shape, aeration is performed and gas bursts out from the side aeration holes 24 of at least three aeration claws 131 , which can greatly increase the aeration range and aeration uniformity of the aeration head 13 .

[0079] Please refer to Figures 5 and 6 , the second embodiment provided by the present invention is:

[0080] A static composting aeration and loosening device, based on the first embodiment, wherein the aeration head 13 further includes an aeration core rod 133 vertically disposed at its center. The aeration core rod 133 is also provided with the main aeration hole 23 and side aeration holes 24 connected to the main aeration hole 23. The upper end of the main aeration hole 23 of the aeration core rod 133 is connected to the lower end of the vent hole 21. Specifically, the main aeration holes 23 on the aeration core rod 133 are arranged along the length of the aeration core rod 133, and the side aeration holes 24 on the aeration core rod 133 are arranged in a row at equal distances on the left and right sides. Furthermore, the side aeration holes 24 on the aeration core rod 133 are also arranged in a row at equal distances on the front and rear sides.

[0081] Based on the first embodiment, Figure 6 As shown, the airflow assembly 2 further includes a secondary Venturi tube 26, which is disposed between the vent 21 and the main aeration hole 23. Specifically, for the aeration claw 131, the secondary Venturi tube 26 is disposed between the main aeration hole 23 of the aeration claw 131 and the hose 25, or between the hose 25 and the vent 21. For the aeration core rod 133, the secondary Venturi tube 26 is disposed between the vent 21 and the main aeration hole 23 of the aeration core rod 133. The secondary Venturi tube 26 further increases the aeration pressure.

[0082] In this embodiment, during the aeration process, the gas entering the primary venturi tube 22 flows into the vent hole 21 of the support rod 12, then flows through the secondary venturi tube 26 and the hose 25 to the main aeration holes 23 of the aeration claw 131 and the main aeration holes 23 of the aeration core rod 133, and flows out through the side aeration holes 24 of the aeration claw 131 and the side aeration holes 24 of the aeration core rod 133, thereby aerating and loosening the static compost.

[0083] Please refer to Figures 1 to 7 , the third embodiment provided by the present invention is:

[0084] A static composting aeration and loosening device, based on the first or second embodiment, further includes a latch assembly 3, comprising a latch seat 31, a first spring 32, a latch 33, a latch nut 34, and a second spring 35. The latch seat 31 is a tubular structure that slides over the exterior of a sleeve rod 11. The sleeve rod 11 has a sidewall formed with vertically arranged sliding grooves 112. A slider 311 extends from the inner side of the latch seat 31, which extends into the sliding groove 112 and slides up and down. The inner end of the slider 311 is fixedly connected to the support rod 12. The first spring 32 is sleeved on the support rod 12 and is located between the latch seat 31 and the sleeve rod 11. The latch seat 31 is located above the connecting rod 14. During use, the aeration head 13 is inserted into the static compost, and the latch seat 31 is located outside the static compost. During movement, the latch seat 31 and the support rod 12 slide up and down relative to the sleeve rod 11. Under the action of the first spring 32, the latch seat 31 and the support rod 12 slide upward relative to the sleeve rod 11, and this action slowly closes the opened aeration claw 131. The latch seat 31 can be used to conveniently control the up and down sliding of the support rod 12.

[0085] A latch hole 312 is formed on the side of the latch seat 31, and the latch pin 33 slides horizontally into the latch hole 312. The latch nut 34 is locked on the outer side of the latch hole 312. The second spring 35 is sleeved on the latch pin 33 and is located in the latch hole 312. Under the action of the second spring 35, the inner end of the latch pin 33 extends out of the latch hole 312. When the inner end of the latch pin 33 is subjected to a force sliding toward the latch hole 312, the latch pin 33 slides toward the latch hole 312.

[0086] Specifically, a tenon 331 is provided at the inner end of the latch 33, and a slot 113 is provided on the side wall of the lower section of the sleeve rod 11. The tenon 331 of the latch 33 is engaged in the slot 113 of the lower section of the sleeve rod 11, so that the support rod 12 stops sliding relative to the sleeve rod 11. During operation, the latch seat 31 and the support rod 12 slide downward relative to the sleeve rod 11. When the tenon 331 of the latch 33 is engaged with the slot 113 of the sleeve rod 11, the support rod 12 stops sliding downward. At this time, the aeration claws 131 of the aeration head 13 are in an open state, and aeration can be carried out. The engagement between the tenon 331 and the slot 113 ensures good structural stability during the aeration process. When the tenon 331 of the latch 33 is disengaged from the slot 113 of the sleeve rod 11, under the action of the first spring 32, the support rod 12 and the latch seat 31 slide upward relative to the sleeve rod 11, and the aeration claws 131 of the aeration head 13 slowly close.

[0087] like Figure 11 As shown, the method of using the static composting aeration and loosening device is as follows:

[0088] Initially, at least three aeration claws 131 of the aeration head 13 are closed to form a truncated cone-shaped aeration head 13, and the aeration head 13 extends into the static compost;

[0089] The support rod 12 slides downward relative to the sleeve rod 11. At this time, the latch assembly 3 slides downward together. Under the action of the connecting rod 14, at least three aeration claws 131 of the aeration head 13 slowly open until the tenon 331 of the latch 33 is stuck in the slot 113 of the sleeve rod 11, and the aeration claws 131 are in the shape of an open claw.

[0090] Ventilate the airflow component 2 for aeration;

[0091] After aeration is completed, the tenon 331 of the latch 33 is disengaged from the slot 113 of the sleeve rod 11. Under the action of the first spring 32, the support rod 12 slides upward relative to the sleeve, and at least three aeration claws 131 of the aeration head 13 slowly close until the aeration head 13 closes in a truncated cone shape, and the aeration head 13 is pulled out of the static compost.

[0092] This operation method, on the one hand, sets the tenon 331 of the latch 33 to be locked in the slot 113 before aeration, so that the structure of the aeration device is stable, and on the other hand, the support rod 12 is operated to slide up and down through the latch seat 31, which is convenient to operate.

[0093] Please refer to Figures 7 and 8 , the fourth embodiment provided by the present invention is:

[0094] A static composting aeration and loosening device, based on Example 3, the pin assembly 3 also includes an annular triangular ring 36, the triangular ring 36 slides up and down in the slot 113, the surface of the triangular ring 36 cooperating with the slot 113 is a vertical surface, the width of the slot 113 is greater than the width of the triangular ring 36, the cross-sectional shape of the tenon 331 is a right triangle with a horizontal upper surface and an acute angle facing the slot 113, the upper surface of the triangular ring 36 is inclined downward and the lower surface is inclined upward, the inclination direction of the upper surface of the triangular ring 36 is consistent with the inclination direction of the lower surface of the pin 33, and the upper surface 1131 of the slot is consistent with the inclination direction of the upper surface of the triangular ring 36.

[0095] Initially, under the action of gravity, the triangular ring 36 is located at the lower position of the slot 113. When the tenon 331 enters the slot 113, the tenon 331 is stuck below the upper surface 1131 of the slot. Figure 7As shown, at this time, the aeration head 13 is claw-shaped and performs aeration operation; after the aeration is completed, continue to press the latch seat 31 downward, and under the action of the inclined upper surface of the triangular ring 36, the tenon 331 of the latch 33 slides toward the latch hole 312, and under the action of the second spring 35, the tenon 331 of the latch 33 is stuck on the lower surface of the triangular ring 36. At this time, stop applying downward force to the latch seat 31, and under the action of the first spring 32, the tenon 331 of the latch 33 drives the triangular ring 36 to move upward. When the triangular ring 36 is located at the upper position of the slot 113, the upper surface of the triangular ring 36 contacts the upper surface 1131 of the slot, and the two surfaces fit together, as shown in FIG. Figure 8 As shown, immediately under the action of the inclined lower surface of the triangular ring 36, the tenon 331 of the latch 33 slides toward the latch hole 312, disengages from the slot 113 to above the slot 113, and then continues to slide upward along the sleeve rod 11 until the aeration claw 131 of the aeration head 13 is closed. This process is achieved by providing a triangular ring 36 that slides relative to the slot 113, so that the tenon 331 of the latch 33 can be disengaged from the slot 113 by applying a downward force to the latch seat 31. This process only requires the latch seat 31 to move downward a short distance, resulting in a flexible and convenient structure.

[0096] Further, such as Figure 8 As shown, the bayonet assembly 3 further includes an upper ring 37 and a lower ring 38, which are fixedly connected to the lower side wall of the sleeve rod 11, and the locking groove 113 is formed between the upper ring 37 and the lower ring 38. The lower surface of the upper ring 37 serves as the upper surface 1131 of the locking groove, and the upper surface of the lower ring 38 serves as the lower surface 1132 of the locking groove.

[0097] like Figure 12 As shown, the method of using the static composting aeration and loosening device is as follows:

[0098] Initially, the triangular ring 36 is in contact with the lower surface of the slot 113 under the action of its own gravity, and at least three aeration claws 131 of the aeration head 13 are closed to form a truncated cone-shaped aeration head 13, and the aeration head 13 extends into the static compost;

[0099] The support rod 12 slides downward relative to the sleeve rod 11, driving the latch assembly 3 to slide downward together. Under the action of the connecting rod 14, at least three aeration claws 131 of the aeration head 13 slowly open until the tenon 331 of the latch 33 is stuck below the upper surface of the slot 113 of the sleeve rod 11, and the aeration claws 131 are in an open claw shape.

[0100] Ventilate the airflow component 2 for aeration;

[0101] After aeration is completed, continue to apply downward force to make the support rod 12 and sleeve rod 11 slide downward. When the tenon 331 touches the upper surface of the triangular ring 36, the tenon 331 moves into the latch hole 312 and immediately extends to the lower surface of the triangular ring 36. At this time, stop applying downward force to the support rod 12 and sleeve rod 11. Under the action of the first spring 32, the support rod 12 and sleeve rod 11 slide upward, and the tenon 331 drives the triangular ring 36 to move upward until it is in contact with the upper surface of the slot 113. Under the action of the inclined lower surface of the triangular ring 36, the tenon 331 moves into the latch hole 312 again. At this time, the tenon 331 of the latch 33 is disengaged from the slot 113 of the sleeve rod 11 and continues to slide upward. At least three aeration claws 131 of the aeration head 13 slowly close until the aeration head 13 closes in a truncated cone shape, and the aeration head 13 is pulled out of the static compost.

[0102] With the help of the triangular ring 36, a slight downward force is applied to the support rod 12 and the sleeve rod 11 to achieve the disengagement of the tenon 331 of the pin 33 from the slot 113 of the sleeve rod 11, which is easy to operate.

[0103] Please refer to Figures 1 to 3 , the fifth embodiment provided by the present invention is:

[0104] A static composting aeration and loosening device, based on the first, second, third, or fourth embodiments, comprises first handles 114 extending leftward and rightward at the upper end of the sleeve rod 11, and second handles 121 extending leftward and rightward at the upper end of the support rod 12. The device is manually controlled, and since the support rod 12 and sleeve rod 11 are relatively long, manual operation of the device is facilitated by grasping the first handle 114 on the sleeve rod 11 and the second handle 121 on the support rod 12 with both hands.

[0105] The method of using the static composting aeration and loosening device is as follows:

[0106] Based on the first, second, third or fourth embodiment, the following steps are added:

[0107] Hold the first handle 114 at the upper end of the sleeve rod 11 with one hand, and hold the second handle 121 at the upper end of the support rod 12 with the other hand;

[0108] Apply downward force to the support rod 12, and the aeration claws 131 of the aeration head 13 slowly open into a claw shape;

[0109] After aeration is completed, when the downward force applied to the support rod 12 stops, the support rod 12 slides upward under the action of the first spring 32 until the aeration claws 131 of the aeration head 13 are closed.

[0110] This manual operation method is easy to operate.

[0111] Please refer to Figure 9 , the sixth embodiment provided by the present invention is:

[0112] A static composting aeration and loosening device, based on the first, second, third, or fourth embodiment, further includes a power assembly 4, wherein the power assembly 4 includes a first telescopic power member, a second telescopic power member, a gantry, a first cross bar 41, and a second cross bar 42, wherein the first telescopic power member is vertically fixed to the gantry, the second telescopic power member is vertically fixed to the output end of the first telescopic power member, the first cross bar 41 is horizontally fixed to the telescopic end of the first telescopic power member, and the second cross bar 42 is horizontally fixed to the telescopic end of the second telescopic power member;

[0113] There are multiple paired sleeve rods 11, support rods 12 and aeration heads 13, which are arranged side by side. The upper end of each sleeve rod 11 is fixed to the first cross bar 41, and the upper end of each support rod 12 is fixed to the second cross bar 42.

[0114] This structure is suitable for automated operation, has high efficiency and saves manpower. The first telescopic power member drives the sleeve rod 11, the support rod 12 and the aeration head 13 to move linearly upward or downward. The second telescopic power member drives the support rod 12 to move linearly upward or downward relative to the sleeve rod 11, and drives the aeration head 13 to close into a truncated cone shape or open into a claw shape.

[0115] The method of using the static composting aeration and loosening device is as follows:

[0116] Based on the first, second, third or fourth embodiment, the following steps are added:

[0117] Initially, the aeration head 13 is located outside the static compost;

[0118] The first telescopic power member drives the first crossbar 41, the second telescopic power member, the second crossbar 42, the plurality of sleeve rods 11 arranged side by side, the support rod 12 and the aeration head 13 to move downward together until the aeration head 13 extends to a suitable position in the static compost;

[0119] The second telescopic power member drives the second crossbar 42 and the support rod 12 to continue to move downward. At this time, the multiple aeration claws 131 of the aeration head 13 slowly open until the aeration head 13 is opened.

[0120] After aeration is completed, the second telescopic power member drives the second crossbar 42 and the support rod 12 to move upward. At this time, the multiple aeration claws 131 of the aeration head 13 slowly close until the aeration head 13 closes and takes on a truncated cone shape.

[0121] The first telescopic power member drives the first cross bar 41, the second telescopic power member, the second cross bar 42, the plurality of sleeve rods 11 arranged side by side, the support rod 12 and the aeration head 13 to continue to move upward until the aeration head 13 rises to the outside of the static compost.

[0122] The above method realizes an automatic aeration process.

[0123] Furthermore, to achieve aeration of different locations along the length of the static compost, the gantry is used to drive the first telescopic power member, the first crossbar 41, the second telescopic power member, the second crossbar 42, the multiple parallel sleeve rods 11, the support rods 12, and the aeration head 13 forward a distance along the length of the static compost, and then the above-described automatic aeration process is repeated. Next, the position of the first telescopic power member along the length of the static compost is continuously changed, and the above-described automatic aeration process is repeated with each change of position until the entire static compost is aerated. This automated operation process saves labor and improves work efficiency.

[0124] In summary, the static composting aeration and loosening device and method of use provided by the present invention have the following beneficial effects:

[0125] 1. By aerating the claw-shaped aeration head 13, the aeration range of a single acupoint is expanded, thereby improving the aeration range and aeration uniformity of a single acupoint;

[0126] 2. The aeration head 13 can be opened into a claw shape, with side aeration holes 24 provided on the upper and lower sides of the opened aeration claw 131. In addition, an aeration core rod 133 can be provided below the center of the aeration head 13 to further ensure the aeration range and aeration uniformity of a single acupuncture point.

[0127] 3. The opening and closing motion control of the aeration head 13 containing multiple aeration claws 131 is achieved through the main motion component 1, and the structure is flexible and ingenious;

[0128] 4. Through the cooperation of the first-stage Venturi tube 22 and the second-stage Venturi tube 26, the aeration pressure, the aeration range of a single acupoint and the aeration uniformity are improved.

[0129] 5. The first handle 114 and the second handle 121 are provided to facilitate manual operation of a single acupuncture point of the loosening device;

[0130] 6. By providing the power assembly 4, it is convenient to carry out the overall automatic aeration operation of the static compost piled into a rectangular parallelepiped, thereby improving the aeration operation efficiency.
