Description

Technical Field

[0001] This utility model relates to the field of fermentation technology, and in particular to a tracked compost turner for fermenting and maturing bio-organic fertilizer. Background Technology

[0002] A compost turner is a machine used to turn over piled materials, commonly used in fertilizer production or other fields requiring composting. Bio-organic fertilizer composting fermentation utilizes animal and plant remains containing fertilizer components, household waste, crop straw, excrement, etc., mixed with soil and minerals, piled up, and fermented and decomposed by microorganisms under high temperature and humidity conditions to produce a bio-organic fertilizer. During the composting fermentation process, the pile generally needs to be turned over every few days.

[0003] The existing turning equipment has a fixed height for the turning components, which cannot adjust the depth according to the thickness of the pile or the temperature distribution. Turning too deeply in the shallow, high-temperature area will cause excessive disturbance to the deep, low-temperature material, wasting energy. Turning too shallowly in the deep, high-temperature area will not effectively dissipate heat, forming an ineffective turning zone. Therefore, a tracked turning machine for the fermentation and maturation of bio-organic fertilizer is proposed to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A tracked compost turner for the fermentation and maturation of bio-organic fertilizer includes:

[0006] A frame-type fixed frame, wherein a partition is provided inside the fixed frame, the partition dividing the cavity of the fixed frame into cavity one and cavity two from top to bottom, and track drive components for driving the fixed frame forward are installed on the bottom of both sides of the fixed frame;

[0007] The turning assembly includes a connecting frame that is movably connected to the partition and a turning device that is rotatably disposed on the connecting frame and located in the cavity two.

[0008] The adjustment assembly includes a cylinder fixedly disposed on the top of the inner wall of the fixed frame, a piston rod movably inserted into the bottom of the cylinder, and an air intake pipe connected to the side wall of the cylinder and located near the top.

[0009] In this process, compressed gas is supplied to the cylinder through the air intake pipe, which pushes the piston rod to move downward. The piston rod drives the connecting frame to move the turner downward, so as to turn the organic fertilizer at different depths.

[0010] As an improvement to the above technical solution, the turner includes a rotating shaft rotatably disposed within the connecting frame, and a plurality of turning rods are fixedly connected to the circumferential surface of the rotating shaft.

[0011] As an improvement to the above technical solution, the connecting frame includes two sets of symmetrically distributed vertical rods and a horizontal rod connecting the two sets of vertical rods. The horizontal rod is located inside the cavity, and a motor is installed on the top of the horizontal rod. A cavity is opened in one of the sets of vertical rods, and the end of the rotating shaft located in the cavity is connected to the motor through a transmission belt.

[0012] As an improvement to the above technical solution, the adjustment assembly further includes an exhaust pipe connected to one side of the cylinder, a spring wound around the surface of the piston rod, and solenoid valves installed on both the exhaust pipe and the intake pipe.

[0013] As an improvement to the above technical solution, a distribution plate is fixedly connected to the bottom of the partition, and multiple sets of air outlets are connected to the bottom of the distribution plate. The distribution plate is connected to the air outlet end of the air outlet pipe.

[0014] The beneficial effects of this utility model are:

[0015] Driven by external force, the turner rotates continuously. Simultaneously, compressed gas controls the extension and retraction of the cylinder piston rod, which drives the connecting frame and the turner to move up and down, achieving dynamic adjustment of the turning depth. This structure can flexibly adjust the turning depth according to the changes in the thickness of the pile, adapting to the needs of different fermentation stages, ensuring that materials at all levels can be fully turned, and improving the overall fermentation efficiency.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] A tracked compost turner for the fermentation and maturation of bio-organic fertilizer includes:

[0021] A frame-type fixed frame 10 is provided inside the fixed frame 10. The partition 11 divides the cavity of the fixed frame 10 from top to bottom into cavity one and cavity two. Track drive components for driving the fixed frame forward are installed on the bottom of both sides of the fixed frame 10.

[0022] The turning assembly includes a connecting frame 20 that is movably connected to the partition 11 and a turning device that is rotatably disposed on the connecting frame 20 and located in the cavity 2.

[0023] The adjustment assembly includes a cylinder 30 fixedly disposed on the top of the inner wall of the fixed frame 10, a piston rod 32 movably inserted into the bottom of the cylinder 30, and an air inlet pipe 31 connected to the side wall of the cylinder 30 and located near the top.

[0024] In this process, compressed gas is supplied to the cylinder 30 through the air inlet pipe 31, which pushes the piston rod 32 to move downward. The piston rod 32 drives the connecting frame 20 to move the turner downward, so as to turn the organic fertilizer at different depths.

[0025] Specifically, the compost temperature is monitored in real time by temperature and position sensors. When the temperature exceeds 65°C, the track drive components on both sides of the fixed frame 10 are controlled to move the equipment towards the overheated area, ensuring that the turning operation covers the high-temperature area. When the equipment moves, the turner rotates under external force. External compressed gas enters the cylinder 30 through the air inlet pipe 31. The gas pressure pushes the piston rod 32 in the cylinder 30 downward. When the piston rod 32 moves down, it drives the connecting frame 20 to descend synchronously, thereby causing the turner on the connecting frame 20 to penetrate deeper into the organic fertilizer pile, increasing the turning depth. If it is necessary to reduce the turning depth, the compressed gas in the cylinder 30 can be released, and the piston rod drives the turner to move upward. By adjusting the height of the turner, it can adapt to organic fertilizer piles of different thicknesses, ensuring that materials at different depths can be fully turned. The turner inserts into the organic fertilizer pile and turns it, exposing the deep materials to the air, increasing the permeability of the organic fertilizer pile, supplementing oxygen, promoting the reproduction of aerobic microorganisms, and accelerating the maturation of materials. At the same time, it can make the pile temperature uniform and avoid local high temperature or anaerobic decay.

[0026] In one embodiment, the compost turner includes a rotating shaft 23 rotatably disposed within the connecting frame 20. Multiple sets of turning rods 24 are fixedly connected to the circumferential surface of the rotating shaft 23. External force drives the rotating shaft 23 to rotate, and the turning rods 24 throw the organic fertilizer at the bottom upwards and outwards, while simultaneously bringing the surface material into the deeper layers, thereby achieving mixing and exchange of materials between the upper and lower layers of the compost pile. During the turning process, the turning rods 24 will form gaps in the compost pile, increasing air circulation channels, providing sufficient oxygen for aerobic microorganisms, and avoiding local anaerobic conditions in the compost pile.

[0027] In one embodiment, the connecting frame 20 includes two sets of symmetrically distributed vertical rods and a horizontal rod connecting the two sets of vertical rods. The horizontal rod is located inside the cavity, and a motor 22 is installed on the top of the horizontal rod. One set of vertical rods has a cavity. One end of the rotating shaft 23 located in the cavity is connected to the motor 22 via a transmission belt. The motor 22 is fixed to the top of the horizontal rod and serves as the power source for the compost turner. Its output shaft is connected to the rotating shaft 23 via a transmission belt 21. The output shaft of the motor 22 drives the transmission belt 21 to rotate, and the friction of the transmission belt drives the rotating shaft to rotate synchronously, ultimately driving the compost turner to rotate. The cavity of the vertical rod can protect the transmission belt from organic fertilizer debris contamination, while avoiding interference between the transmission components and the vertical rod structure, ensuring the stability of power transmission.

[0028] In one embodiment, the adjustment assembly further includes an outlet pipe 34 connected to one side of the cylinder 30. A spring 33 is wound around the surface of the piston rod 32. Solenoid valves are installed on both the outlet pipe 34 and the inlet pipe 31. When it is necessary to increase the turning depth, the solenoid valve on the inlet pipe 31 is opened, and the solenoid valve on the outlet pipe 34 is closed at the same time. External compressed gas enters the cylinder 30 through the inlet pipe 31. The air pressure inside the cylinder 30 gradually increases. The increased air pressure generates a downward thrust, which overcomes the preload of the spring 33 wound around the surface of the piston rod 32 and pushes the piston rod 32 to extend downward. The downward movement of the piston rod 32 drives the connecting frame 20, the rotating shaft 23 and the turning rod 24 to move downward synchronously, so that the depth of the turning rod inserted into the organic fertilizer pile increases, and the turning of deeper materials is achieved.

[0029] When it is necessary to reduce the turning depth, the solenoid valve of the air inlet pipe 31 is closed, and the solenoid valve on the air outlet pipe 34 is opened at the same time. The compressed gas in the cylinder 30 is discharged through the air outlet pipe 34, and the air pressure in the cylinder 30 decreases. As the air pressure in the cylinder 30 decreases, the originally compressed spring 33 recovers its deformation, releases elastic potential energy, and generates an upward restoring force, which pushes the piston rod 32 to retract upward. The piston rod 32 moves upward, causing the connecting frame 20 and the turning assembly to rise as a whole. The turning rod 24 is pulled upward from the organic fertilizer pile, and the insertion depth is reduced to meet the turning needs of shallow materials.

[0030] In one embodiment, a distribution plate 12 is fixedly connected to the bottom of the partition 11. Multiple sets of air outlets are connected to the bottom of the distribution plate 12. The distribution plate 12 is connected to the air outlet end of the air outlet pipe 34. When gas is discharged from the air outlet pipe 34, the gas enters the distribution plate 12. At this time, the turning rod 24 pulls the material upwards, loosening it. The gas ejected from the air outlets can penetrate the gaps between the materials more efficiently, achieving simultaneous "turning-ventilation." The turning rod 24 breaks up material clumps, creating ventilation channels, while the air outlets use the excess air from the cylinder 30 to fill the channels, specifically addressing the issue of deep organic fertilizer piles.

[0031] The problem of insufficient oxygen supply to the fermentation layer accelerates the fermentation and maturation process.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
