Description

Technical Field

[0001] This invention relates to the field of organic fertilizer production technology, specifically to a compost turning and mixing device for organic fertilizer production. Background Technology

[0002] The organic fertilizer production process mainly includes core steps such as raw material pretreatment, fermentation and maturation, crushing and screening, granulation, drying and cooling, and packaging. Among these, fermentation and maturation is a crucial step in the organic fertilizer production process, requiring strict control of parameters such as moisture, temperature, and carbon-nitrogen ratio throughout the entire process. Organic fertilizer composting fermentation mainly employs methods such as windrow composting, trough composting, reactor composting, and anaerobic composting. Windrow composting, due to its advantages of low initial investment, simple operation, and low energy consumption, is an ideal choice for many small and medium-sized producers.

[0003] During composting, the organic fertilizer needs to be turned regularly according to the ambient temperature and humidity to optimize the fermentation conditions and compost quality. Currently, the equipment used in the windrow composting method for turning the fertilizer is mostly a tracked or wheeled turning roller that spans the compost pile, or a side-throwing turning device. Of these two types of equipment, the cross-type turning device uses a horizontally rotating high-speed turning roller to turn the piled organic fertilizer material backward. During the entire turning process, the organic fertilizer material is stirred and mixed in a limited space under the high-speed movement of the turning roller. The middle and bottom layers of fertilizer have short contact time with air and cannot be fully aerated, resulting in insufficient supply of nutrients for aerobic microorganisms in the organic fertilizer, leading to uneven fertilizer fermentation and making it difficult to achieve the expected fermentation efficiency. The side-throwing turning device, when turning the windrows, turns the windrow fertilizer to the side open space, which occupies a larger area of ​​land. In addition, the two types of turning and composting equipment mentioned above have relatively simple functions. When it is necessary to adjust the carbon-nitrogen ratio and humidity inside the compost, manual assistance is required to sprinkle and add materials or agents, which is labor-intensive.

[0004] Based on the above problems, we propose a composting and mixing equipment for organic fertilizer production. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a composting and mixing device for organic fertilizer production.

[0006] This invention provides a composting and mixing device for organic fertilizer production, comprising a chassis. A lifting conveyor is mounted on the front end of the chassis via a lifting mechanism. A shovel hopper is installed at the front end of the lifting conveyor to facilitate the smooth transfer of the accumulated organic fertilizer. Two sets of screw conveyors, a storage assembly, and a mixing bin are mounted on the rear end of the chassis via supports. Receiving hoppers are installed at the inlet ends of the two sets of screw conveyors. The lifting conveyor is a chain-plate Z-type conveyor, with conveying hoppers evenly spaced on the conveyor chain. During operation, the conveying hoppers lift the organic compost falling onto the lifting conveyor to above the chassis, allowing it to fall into the receiving hoppers and be further conveyed to a higher position by the two sets of screw conveyors. This provides a certain height foundation for subsequent natural descent and also facilitates sufficient contact between the aerobic microorganisms in the original compost and the air, achieving adequate aeration.

[0007] When the equipment is idle, to avoid damage to the front shovel of the lifting conveyor, the entire lifting conveyor needs to be adjusted in height using a lifting mechanism. Therefore, there are two sets of lifting mechanisms used to install the lifting conveyor, which are symmetrically installed on both sides of the lifting conveyor. The lifting mechanism specifically includes a column and a guide rail slider. The column is erected on the chassis, and the column and the chassis are preferably fixed by a detachable bolt assembly. In addition, the column has a straight groove and a guide rail groove on the side close to the lifting conveyor. The guide rail slider is installed on the frame of the lifting conveyor, and the guide rail slider slides in cooperation with the guide rail groove on the column. A mounting block is fixed at the position of the guide rail slider corresponding to the straight groove. A telescopic cylinder is installed in the straight groove at the bottom of the mounting block. The two ends of the telescopic cylinder are hinged to the mounting block and the chassis, respectively. Through the telescopic movement of the telescopic cylinder, in conjunction with the cooperation between the guide rail slider and the column, the horizontal height of the lifting conveyor is adjusted. The telescopic cylinder is preferably a hydraulic telescopic cylinder.

[0008] Furthermore, to facilitate the transfer of organic compost to the two sets of screw conveyors, the receiving hopper is located at the bottom of the material drop end of the lifting conveyor; this facilitates the receipt of organic fertilizer falling from the end of the lifting conveyor and the introduction of the fertilizer into the two sets of screw conveyors. Moreover, to facilitate the guidance of the organic fertilizer falling into the receiving hopper into the two sets of screw conveyors, the middle of the receiving hopper is provided with an inverted V-shaped guide plate. Furthermore, thanks to the design of the guide plate in the middle of the receiving hopper, space can be left between the bottom of the receiving hopper and the chassis for installing the engine.

[0009] Furthermore, both the storage assembly and the mixing silo are located between the two sets of screw conveyors, with the storage assembly situated at the top of the mixing silo. The storage assembly includes a funnel-shaped storage silo and a liquid storage tank. The storage assembly primarily stores materials used to adjust the carbon-nitrogen ratio within the compost and microbial agents used to adjust the microbial community. A discharge assembly is installed at the bottom of the storage assembly, with its bottom outlet facing the inner side of the mixing silo near the center. The mixing silo is located at the discharge point of the two sets of screw conveyors. At the bottom, a mixing mechanism is installed inside the mixing hopper. The discharge assembly includes a discharge port installed at the bottom outlet of the storage hopper. A baffle for adjusting the opening degree of the discharge port is slidably inserted in the middle of the discharge port. By pulling the baffle, the overlap between the perforation in the middle of the baffle and the discharge port is adjusted, thereby adjusting the opening degree of the discharge port and thus adjusting the material falling speed. In order to prevent the baffle from being displaced by vibration during equipment operation, a locking bolt for positioning the baffle can be set between the baffle and the discharge port.

[0010] Furthermore, to facilitate the addition of microbial agents, the discharge assembly also includes a conveying pump installed on the side of the storage tank. The pump inlet of the conveying pump is connected to the bottom of the storage tank, while the pump outlet is connected to a distribution pipe via a pipeline. An electromagnetic flow valve is installed on the pipeline connecting the conveying pump and the distribution pipe to control and adjust the amount of microbial agent added. The distribution pipe is located inside the mixing silo, and spray nozzles are installed at equal intervals on the distribution pipe to evenly spray the microbial agent into the organic fertilizer. The design of the mixing silo, in conjunction with the mixing mechanism, is mainly to stir and mix the organic fertilizer conveyed by the two sets of screw conveyors, breaking up any clumps, so that the organic compost can be fully aerated. Moreover, during the stirring and mixing process, if auxiliary materials or microbial agents need to be added, the stirring and mixing process allows the auxiliary materials or microbial agents to be added evenly into the organic fertilizer, which is more effective than manual addition by following the equipment.

[0011] Furthermore, to facilitate the smooth transfer of the stacked organic fertilizer into the lifting conveyor, the shovel bucket includes two side plates fixed to the front sides of the lifting conveyor frame. A shovel plate is welded between the two side plates. The front ends of both side plates are inclined outward to form an flared shape, so as to gather the fertilizer scattered on the outside back to the center for shovel plate to pick up. In addition, to ensure that the shovel bucket can effectively cooperate with the front end of the lifting conveyor and minimize the gap between the shovel bucket and the lifting conveyor, an arc groove is integrally formed at the end of the shovel plate near the lifting conveyor to facilitate the passage of the front chain plate and the shovel bucket of the lifting conveyor.

[0012] Furthermore, in order to save installation space for each component and shorten the front-to-back span of the equipment, and also to transport the turned organic fertilizer to a certain height to provide a height foundation for subsequent fertilizer mixing, addition of auxiliary materials, and natural dumping and piling, both sets of screw conveyors are installed at an upward angle of 45-60 degrees on both sides of the chassis. Moreover, the discharge ports of the two sets of screw conveyors are set at an inclination towards each other inside the top inlet of the mixing silo. When the fertilizer output from the two sets of screw conveyors falls, it falls towards the center of the mixing silo. On the one hand, this can prevent the fertilizer from scattering, and on the other hand, it can concentrate the fertilizer landing point to facilitate the addition of auxiliary materials and microbial agents.

[0013] Furthermore, the bottom of the mixing hopper is provided with a constricted discharge port. The discharge port can, to some extent, concentrate the landing point of the organic fertilizer after turning and composing. In addition, since the equipment operates slowly during the entire turning and composing process, in order to prevent the organic fertilizer that has been turned and composing from piling up again at the rear end of the equipment and covering the steering wheels below, thus affecting the turning of the equipment, an arc-shaped tail plate is also installed at the rear end of the chassis using a bracket, and a protective panel is used to form a protective structure at the rear of the chassis.

[0014] Furthermore, in order to achieve the turning and scattering of organic fertilizer and the mixing of auxiliary materials or microbial agents, the mixing mechanism includes a mixing motor installed on the side of the mixing hopper, and a rotating shaft rotatably installed inside the mixing hopper and connected to the output end of the mixing motor. Several turning frames are installed at equal intervals on the rotating shaft, and a first turning plate and a second turning plate are installed at the end and middle of each turning frame. The first turning plate and the second turning plate are set at a relatively designed inclined angle.

[0015] Furthermore, to facilitate equipment movement and steering, a drive axle and a steering axle are respectively installed at the front and rear ends of the chassis. Drive wheels are installed at both ends of the drive axle, and steering wheels are installed at both ends of the steering axle. In addition, a steering gear assembly is installed at the rear end of the chassis, which is integrated with the steering axle. A steering servo motor is installed at the drive port of the steering gear assembly. The steering servo motor drives the actuator of the steering gear assembly to move, thereby driving the steering wheels at both ends of the steering axle to turn.

[0016] Furthermore, in order to enable the equipment to move forward, a power compartment is provided in the middle of the chassis and at the bottom of the receiving hopper. The drive axle is connected to the engine assembly inside the power compartment via a universal joint drive shaft. The engine assembly consists of an internal combustion engine and an electric gearbox. The output shaft of the internal combustion engine is connected to the electric gearbox, and the drive axle is connected to the output shaft of the electric gearbox via the universal joint drive shaft to realize power transmission. In order to facilitate the control of the equipment, a central control computer for controlling the speed and the organic fertilizer conveying speed is also installed in the power compartment. The central control computer adopts a programmable PLC intelligent terminal module.

[0017] The power compartment is also equipped with a hydraulic system linked to the internal combustion engine, which provides hydraulic power to the telescopic cylinder in the lifting mechanism. It should be noted that the lifting conveyor and screw conveyor are both electrically driven. In order for the lifting conveyor, screw conveyor and mixing motor to operate normally, the entire equipment can be powered by an external tow cable or by a high-power diesel generator installed on the chassis.

[0018] Furthermore, the chassis is equipped with ladders on both sides to facilitate operators in adding auxiliary materials or microbial agents, as well as performing maintenance on higher parts of the equipment.

[0019] Furthermore, to facilitate automated operation of the equipment, a set of visual detection components is installed on the outside of the columns in both sets of lifting mechanisms to monitor the direction of the equipment's travel path in real time.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention integrates fertilizer turning and mixing with auxiliary materials. During the entire turning process, the fertilizer can fully contact the air, allowing aerobic microorganisms to receive sufficient oxygen, ensuring adequate aeration and uniform fermentation of the organic fertilizer, thereby improving compost quality. Furthermore, during the turning process, materials to adjust the carbon-nitrogen ratio and moisture content, as well as microbial agents to adjust the microbial fermentation flora, can be added according to actual needs. This eliminates the need for manual addition while following the equipment, greatly reducing labor intensity. Moreover, this equipment does not require side-throwing of fertilizer during the turning of windrow compost, thus requiring relatively less space. Attached Figure Description

[0034] The following illustrations disclose several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details are not intended to limit the invention. That is, in some embodiments of the invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the illustrations in a simple schematic manner.

[0035] Example

[0036] To address the shortcomings of current equipment used in the turning and mixing of windrow compost in bio-organic fertilizer production—namely, insufficient aeration, large space requirements, and inability to add auxiliary materials—we propose a compost turning and mixing device for organic fertilizer production. This device integrates fertilizer turning and mixing with the addition of auxiliary materials. Throughout the turning process, the fertilizer can fully contact the air, ensuring adequate aeration and promoting uniform fermentation, thus improving compost quality. Furthermore, during the turning process, materials can be added to adjust the carbon-nitrogen ratio and moisture content (e.g., dry materials such as wood ash, dry soil, straw, sawdust, or wet materials such as chopped vegetable leaves and fruit peels), as well as microbial agents to adjust the microbial fermentation flora (e.g., EM bacteria). Manual addition is unnecessary, significantly reducing labor intensity. Moreover, this device eliminates the need for side-throwing of fertilizer during the turning and mixing of windrow compost, resulting in relatively lower site requirements. The specific design is as follows:

[0037] Please see Figure 1-2This embodiment provides a composting and mixing device for organic fertilizer production, including a chassis 1. A lifting conveyor 3 is installed at the front end of the chassis 1 via a lifting mechanism 2. To facilitate the smooth introduction of the accumulated organic fertilizer into the lifting conveyor 3, a shovel hopper 16 is installed at the front end of the lifting conveyor 3. Two sets of screw conveyors 5, a storage assembly, and a mixing bin 6 are respectively installed at the rear end of the chassis 1 via a bracket 4. A receiving hopper 12 is installed at the inlet end of the two sets of screw conveyors 5. The lifting conveyor 3 is a chain-plate Z-type conveyor. The conveyor chain plate of the lifting conveyor 3 has hoppers 301 installed at equal intervals. During operation, the hoppers 301 lift the organic compost falling onto the lifting conveyor 3 to above the chassis 1, so that it can fall into the receiving hopper 12 and be further conveyed to a higher position by the two sets of screw conveyors 5. This provides a certain height foundation for subsequent natural descent and also facilitates sufficient contact between the aerobic microorganisms in the original compost and the air, achieving adequate aeration.

[0038] Please see Figure 3-4 When the equipment is idle, to avoid damage to the front shovel 16 of the lifting conveyor 3, the entire lifting conveyor 3 needs to be adjusted in height using the lifting mechanism 2. Therefore, there are two sets of lifting mechanisms 2 used to install the lifting conveyor 3, which are symmetrically installed on both sides of the lifting conveyor 3. The lifting mechanism 2 specifically includes a column 201 and a guide rail slider 204. The column 201 is installed upright on the chassis 1, and the column 201 and the chassis 1 are preferably fixed by detachable bolt assembly. In addition, the column 201 has a straight groove 202 and a guide rail groove 203 on the side close to the lifting conveyor 3. The guide rail slider 204 is installed on the frame of the lifting conveyor 3, and the guide rail slider 204 slides in cooperation with the guide rail groove 203 on the column 201. The guide rail slider 204 is fixed with a mounting block 205 at the position corresponding to the straight groove 202. A telescopic cylinder 206 is installed in the straight groove 202 at the bottom of the mounting block 205. The two ends of the telescopic cylinder 206 are hinged to the mounting block 205 and the chassis 1, respectively. Through the telescopic movement of the telescopic cylinder 206, in conjunction with the cooperation between the guide rail slider 204 and the column 201, the horizontal height of the lifting conveyor can be adjusted. The telescopic cylinder 206 is preferably a hydraulic telescopic cylinder.

[0039] Please see Figure 5-6To facilitate the transfer of organic compost to the two sets of screw conveyors 5, the receiving hopper 12 is located at the bottom of the material drop end of the lifting conveyor 3; so as to receive the organic fertilizer falling from the end of the lifting conveyor 3 and guide the fertilizer into the two sets of screw conveyors 5. In addition, to facilitate the guidance of the organic fertilizer falling into the receiving hopper 12 into the two sets of screw conveyors 5, the middle of the receiving hopper 12 is provided with an inverted V-shaped guide plate 121. Moreover, with the help of the design of the guide plate 121 in the middle of the receiving hopper 12, space can be left between the bottom of the receiving hopper 12 and the chassis 1 for installing the engine.

[0040] Please see Figure 5-7 The storage assembly and mixing silo 6 are both located between the two sets of screw conveyors 5, with the storage assembly situated on top of the mixing silo 6. The storage assembly includes a funnel-shaped storage silo 8 and a liquid storage tank 9. The storage assembly is primarily used to store materials for adjusting the carbon-nitrogen ratio within the compost and microbial agents for adjusting the microbial community. A discharge assembly is installed at the bottom of the storage assembly, with its bottom outlet facing the inner side of the mixing silo 6 near the center. The mixing silo 6 is located at the bottom of the discharge end of the two sets of screw conveyors 5. A mixing mechanism 7 is installed inside the mixing silo 6. The component includes a discharge port 801 installed at the bottom outlet of the storage silo 8. A baffle 802 for adjusting the opening degree of the discharge port 801 is slidably inserted into the middle of the discharge port 801. By pulling the baffle 802, the overlap between the through hole in the middle of the baffle 802 and the discharge port 801 can be adjusted, thereby adjusting the opening degree of the discharge port 801 and thus adjusting the material falling speed. In order to prevent the baffle 802 from being displaced by vibration during equipment operation, a locking bolt for positioning the baffle 802 can be provided between the baffle 802 and the discharge port 801.

[0041] To facilitate the addition of microbial agents, the discharge assembly also includes a conveying pump 10 installed on the side of the storage tank 9. The pump inlet of the conveying pump 10 is connected to the bottom of the storage tank 9, while the pump outlet of the conveying pump 10 is connected to a distribution pipe 23 via a pipeline. An electromagnetic flow valve 22 is installed on the pipeline connecting the conveying pump 10 and the distribution pipe 23 to control and adjust the amount of microbial agents added. The distribution pipe 23 is located inside the mixing silo 6, and spray nozzles are installed at equal intervals on the distribution pipe 23 to evenly spray the microbial agents into the organic fertilizer. The design of the mixing silo 6 in conjunction with the mixing mechanism 7 is mainly to stir and mix the organic fertilizer conveyed by the two sets of screw conveyors 5, break up clumps, and ensure that the organic compost can be fully aerated. Moreover, during the stirring and mixing process, if auxiliary materials or microbial agents need to be added, the stirring and mixing process can ensure that the auxiliary materials or microbial agents are evenly added into the organic fertilizer, which is more effective than manual addition by following the equipment.

[0042] Please see Figure 10To facilitate the smooth transfer of stacked organic fertilizer into the lifting conveyor 3, the shovel hopper 16 includes two side plates 161 fixed to the front side frames of the lifting conveyor 3. A shovel plate 162 is welded between the two side plates 161. The front ends of the two side plates 161 are inclined outward to form an flared shape, so as to gather the fertilizer scattered on the outside back to the middle so that it can be scooped up by the shovel plate 162. In addition, in order to enable the shovel hopper 16 to effectively cooperate with the front end of the lifting conveyor 3 and minimize the gap between the shovel hopper 16 and the lifting conveyor 3, an arc groove 163 is integrally formed at the end of the shovel plate 162 near the lifting conveyor 3 to facilitate the passage of the front chain plate of the lifting conveyor 3 and the conveying hopper 301.

[0043] Please see Figure 1-4 To save installation space for each component and shorten the front-to-back span of the equipment, and also to transport the turned organic fertilizer to a certain height to provide a height foundation for subsequent fertilizer mixing, addition of auxiliary materials, and natural dumping and piling, the two sets of screw conveyors 5 are installed at an upward angle of 45-60 degrees on both sides of the chassis 1. Moreover, the discharge ports of the two sets of screw conveyors 5 are set at an inclination towards each other inside the top inlet of the mixing bin 6. When the fertilizer output from the two sets of screw conveyors 5 falls, it falls towards the center of the mixing bin 6. This can prevent the fertilizer from scattering and concentrate the fertilizer drop point, which is convenient for the addition of auxiliary materials and microbial agents.

[0044] Please see Figure 5 As shown, the bottom of the mixing hopper 6 is equipped with a constricted discharge port 601. The discharge port 601 helps to concentrate the organic fertilizer's fall point after turning. Additionally, since the entire turning process is slow, to prevent the turned organic fertilizer from piling up again at the rear of the equipment and covering the steering wheel 14, thus affecting the equipment's steering, please refer to [reference needed]. Figure 1-2 As shown, an arc-shaped tailplate 11 is also installed at the rear end of the chassis 1 using a bracket 4, and the tailplate forms protection at the rear of the chassis 1.

[0045] Please see Figure 8 As shown, in order to realize the turning and mixing of organic fertilizer and auxiliary materials or microbial agents, the mixing mechanism 7 includes a mixing motor 701 installed on the side of the mixing bin 6, and a rotating shaft 702 rotatably installed inside the mixing bin 6 and connected to the output end of the mixing motor 701. Several turning frames 703 are installed at equal intervals on the rotating shaft 702. Each turning frame 703 has a first turning plate 704 and a second turning plate 705 installed at its end and middle. The first turning plate 704 and the second turning plate 705 are both set at a relatively designed inclined angle.

[0046] Please see Figure 6 , Figure 9As shown, to facilitate equipment movement and steering, a drive axle 24 and a steering axle 20 are respectively installed at the front and rear ends of the chassis 1. Drive wheels 13 are installed at both ends of the drive axle 24, and steering wheels 14 are installed at both ends of the steering axle 20. In addition, a steering gear assembly 21, which is installed together with the steering axle 20, is also installed at the rear end of the chassis 1. A steering servo motor 15 is installed at the drive port of the steering gear assembly 21. The steering servo motor 15 drives the actuator of the steering gear assembly 21 to move, thereby driving the steering wheels 14 at both ends of the steering axle 20 to turn. It should be noted that the steering gear assembly 21 and the steering axle 20 are conventional technologies in the automotive field. Therefore, the design and matching method of the steering gear assembly 21 and the steering axle 20 will not be described again.

[0047] Additionally, please see Figure 1-6 As shown, in order to enable the equipment to move forward, a power compartment 19 is set in the middle of the chassis 1 and at the bottom of the receiving hopper 12. The drive axle 24 is connected to the engine assembly inside the power compartment 19 through a universal joint drive shaft. To be further explained, the engine assembly consists of an internal combustion engine and an electric gearbox. The output shaft of the internal combustion engine is connected to the electric gearbox, and the drive axle 24 is connected to the output shaft of the electric gearbox through a universal joint drive shaft to realize power transmission. In order to facilitate the control of the equipment, a central control computer for controlling the speed and the organic fertilizer conveying speed is also installed in the power compartment 19. The central control computer adopts a programmable PLC intelligent terminal module.

[0048] The power compartment 19 is also equipped with a hydraulic system linked to the internal combustion engine. This hydraulic system adopts the conventional vehicle-mounted hydraulic system and is used to provide hydraulic power to the telescopic cylinder 206 in the lifting mechanism 2. It should be noted that the lifting conveyor 3 and the screw conveyor 5 are both electrically driven. In order for the lifting conveyor 3, the screw conveyor 5 and the mixing motor 701 to operate normally, the entire equipment can be powered by an external tow cable or by a high-power diesel generator installed on the chassis 1.

[0049] The chassis 1 is also equipped with ladders 18 on both sides to facilitate operators to add auxiliary materials or microbial agents, as well as to carry out maintenance on the equipment at higher positions.

[0050] To facilitate automated operation of the equipment, a set of visual detection components 17 is installed on the outside of the columns 201 in both sets of lifting mechanisms 2. These components are used to monitor the direction of the equipment's movement path in real time. The visual detection component 17 includes a high-definition camera module, a detection radar, and a data analysis processor. It is used to acquire and monitor the image data in front of the equipment in real time and analyze the equipment's forward path by monitoring and capturing the image data. The data analysis processor in the visual detection component 17 is also connected to the central control computer inside the power compartment 19 to achieve information sharing, so that the central control computer can adjust the equipment's movement posture in real time based on the data.

[0051] It should be further explained that the high-definition camera module, detection radar, and data analysis processor in the vision inspection component 17, as well as the central control computer in the power compartment 19, are all conventional components in the fields of intelligent vehicles and intelligent robots. Their working principles and analysis logic programs are publicly available and conventional technologies in the fields of intelligent vehicles and intelligent robots, so they will not be repeated in this article.

[0052] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
