Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a fermentation device for organic materials of plant and animal origins in different proportions. Background Art

[0002] With the increasing awareness of sustainable development and environmental protection, the fermentation technology of organic materials has become increasingly important in the fields of agriculture, environmental protection and energy. Plant-based and animal-based organic materials, such as crop straw and animal manure, are the main raw materials in the fermentation process. After mixing, these materials are converted into fertilizers, biofuels or other useful products through the action of microorganisms, which not only reduces environmental pollution but also promotes the recycling of resources.

[0003] At present, when fermentation equipment processes plant-based and animal-based materials, due to the differences in physical and chemical properties between plant-based and animal-based materials, the added mixing ratio of the two will directly affect the quality of organic fertilizer.

[0004] However, the existing fermentation devices are often unable to effectively control the ratio of plant-based and animal-based materials when loading, and usually adopt manual control methods. This method not only requires a large amount of labor, but also has poor ratio control accuracy, resulting in unstable fermentation effects and affecting the quality and stability of the final organic fertilizer.

[0005] Therefore, in order to improve the convenience of controlling the ratio of plant and animal sources during mixed fermentation, we proposed a fermentation device for organic materials with different ratios of plant and animal sources. Summary of the invention

[0016] Furthermore, both sides of the material distribution hopper are formed with an outward expansion portion, and a spiral guide bar is fixedly installed in the outward expansion portion, and the head and tail opposite parts of the spiral guide bar face the bottom of the material distribution hopper;

[0017] The guide shaft fits and slides on the inner side of the spiral guide bar.

[0018] Furthermore, the leveling mechanism includes two brackets slidably connected to both sides of the hopper, an electric roller is rotatably connected between the two brackets, and a material guide plate is also fixedly connected to the inner side of the hopper, forming a material discharge channel between the material guide plate and the electric roller.

[0019] Furthermore, two displacement mechanisms are provided on both sides of the hopper, and the two displacement mechanisms on each side are connected to two adjacent brackets, so as to change the width of the material discharge channel by controlling the lateral movement of the electric roller.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1-10 An embodiment of the present invention discloses a fermentation device for organic materials of plant and animal origin in different proportions. Specifically, the fermentation device comprises a fermentation tank 1 and a feeding device 2. Preferably, the fermentation tank 1 described in this embodiment is provided with a stirring device, such as a stirring rod driven by a motor, so as to fully stir the plant and animal sources and improve the fermentation efficiency.

[0040] Reference Figure 1 The feeding device 2 includes a frame 21, a hopper 22 and a conveying mechanism 23 connected to the bottom of the hopper 22 are fixedly installed on the top of the frame 21. Specifically, the conveying mechanism 23 described in this embodiment is an auger conveying mechanism, and its specific structure is the prior art, which will not be described in detail again;

[0041] Two sub-hoppers 24 are fixedly installed above the hopper 22 through a bracket 20, a feeding mechanism 25 is arranged inside the sub-hopper 24, and two leveling mechanisms 26 are also arranged on the inner side of the hopper 22. The two leveling mechanisms 26 are relatively distributed at the discharge ports of the two sub-hoppers 24.

[0042] That is, in the present invention, two sub-hoppers 24 are designed to realize the separate addition of plant sources and animal sources. When the two materials are fed into the hopper 22, the feeding amount of the plant source and the animal source can be controlled by changing the rotation speed of the feeding mechanism 25, thereby achieving the purpose of adding different proportions. Thereafter, the conveying mechanism 23 conveys the two materials to the fermentation tank 1 to realize the mixing and fermentation of the two materials.

[0043] Reference Figure 3 , Figure 4 In some embodiments, the feeding mechanism 25 of the present invention includes a turntable 251 rotatably connected to the inner side of the bottom of the sub-hopper 24, and the inner side of the sub-hopper 24 has a guide portion 241 that fits the turntable 251. The guide portions 241 have two and are respectively located on both sides of the turntable 251. The distance between the two opposite guide portions 241 is adapted to the width of a material trough 252, so that the material in the sub-hopper 24 can be ensured to enter the material trough 252 in the turntable 251 along the guide portion 241;

[0044] The outer circumference of the rotating disk 251 is provided with a plurality of material troughs 252 , and the outer side of the material distribution hopper 24 is fixedly mounted with a motor 253 for driving the rotating disk 251 to rotate.

[0045] That is to say, in the feeding process, the plant source and the animal source are first added into the two sub-hoppers 24 respectively, and the motor 253 drives the turntable 251 to rotate, and the materials fall into the trough 252 of the turntable 251. Through the continuous rotation of the turntable 251, the materials in the trough 252 are rotated downward until they fall into the hopper 22.

[0046] During the feeding process, the rotation speed of the two motors 253 can be controlled to adjust the rotation and unloading speed of the turntable 251, so as to achieve different proportions of control of the added amounts of plant sources and animal sources. Preferably, the motor 253 described in the present invention is configured as a servo motor, and the feeding ratio of the plant source and the animal source is determined by the rotation speed ratio of the two motors 253. The structural design is simple, which greatly improves the convenience of operation.

[0047] Reference Figure 5 , Figure 6 On the basis of the above-mentioned embodiment, a plurality of through grooves 254 are further provided on the end surface of the turntable 251 in the present invention, and the through grooves 254 are opposite to the material groove 252 and form a sheet-shaped portion at the material groove 252;

[0048] A knocking assembly for knocking the sheet portion is provided on the inner side of the through groove 254, that is, the knocking assembly provided in the present invention is used to knock the sheet portion. The purpose of this design is that when the turntable 251 is feeding materials and when the material trough 252 is pouring materials downward, the material trough 252 is knocked by the knocking assembly, thereby preventing the material from sticking to the inner wall of the material trough 252 and causing the problem of incomplete material discharge.

[0049] In a preferred embodiment, the knocking assembly in the present invention includes a telescopic rod 255 fixed in the through slot 254, the telescopic end of the telescopic rod 255 is fixedly connected with a knocking head 256, and the knocking head 256 can be set as a metal part, wherein a guide shaft 257 is also fixedly connected to the telescopic end of the telescopic rod 255, and a spring 258 is fixedly connected between the guide shaft 257 and the bottom of the through slot 254. Of course, the spring 258 described in this embodiment is sleeved on the outside of the telescopic rod 255. In this embodiment, the telescopic rod 255 can be driven to retract by moving the guide shaft 257. When the guide shaft 257 loses its restriction, it rebounds quickly under the control of the spring 258, which can drive the knocking head 256 to knock on the sheet part, thereby improving the unloading stability of the material trough 252 during rotation.

[0050] Furthermore, the material troughs 252 described in this embodiment are distributed evenly along the outer circumference of the turntable 251. Of course, the through grooves 254 should also be adapted to be provided with four. In this way, four material unloading movements can be achieved every time the turntable 251 rotates one circle. Of course, technical personnel in the relevant field can also adjust the number of the material troughs 252 according to actual needs to change the feeding amount of the turntable 251 per rotation. This method is only a conventional means for technical personnel in the relevant field and will not be elaborated here.

[0051] Reference Figure 4 , Figure 6 Further, in order to realize the guiding drive of the guide shaft 257, an outward expansion portion 242 is formed on both sides of the distribution hopper 24 in the present invention, and a spiral guide bar 243 is fixedly installed in the outward expansion portion 242, that is, the outward expansion portion 242 described in the present invention is used to accommodate the spiral guide bar 243 and the guide shaft 257. In addition, the spiral guide bar 243 is at least one circle, and the head and tail ends are a certain distance apart to facilitate the movement of the guide shaft 257. In addition, the spiral guide bar 243 described in this embodiment has a radius that gradually increases from the inside to the outside, and the head and tail opposite parts of the spiral guide bar 243 face the bottom of the distribution hopper 24;

[0052] The guide shaft 257 fits and slides on the inner side of the spiral guide bar 243 .

[0053] When the turntable 251 is rotating to discharge materials, when a trough 252 rotates to the bottom of the hopper 24, the materials will fall downward into the hopper 22 due to gravity. During this process, the guide shaft 257 on the telescopic end of the telescopic rod 255 will move in contact with the spiral guide bar 243. Since the radius of the spiral guide bar 243 is gradually increasing, the guide shaft 257 will shrink along the inner circle of the spiral guide bar 243, driving the telescopic rod 255 to shrink. When the trough 252 rotates to the bottom, the corresponding guide shaft 257 will move along the spiral guide bar 243. The inner side of the guide bar 243 is separated. At this time, under the control of the spring 258, the telescopic rod 255 rebounds quickly, so that the knocking head 256 knocks on the sheet part, completing the knocking of the material trough 252 to ensure that the material in the material trough 252 can be discharged smoothly. Thereafter, when the telescopic rod 255 is extended, the guide shaft 257 on its outside will contact the outer circle of the spiral guide bar 243. When the turntable 251 rotates, the guide shaft 257 will continue to shrink along the spiral guide bar 243, so as to realize the reciprocating knocking motion of the material trough 252 to ensure the stability of material discharge.

[0054] Reference Figure 7 , Figure 8 Of course, considering that the turntable 251 is used for unloading in the present invention, the dropped materials will form a pile-like structure. In order to ensure that the materials can be continuously conveyed and the plant source and the animal source can be fully mixed when entering the conveying mechanism 23, the leveling mechanism 26 in the present invention includes two brackets 261 slidably connected to the two sides of the hopper 22, and a motorized roller 262 is rotatably connected between the two brackets 261. A guide plate 263 is also fixedly connected to the inner side of the hopper 22, and a material unloading channel is formed between the guide plate 263 and the motorized roller 262, that is, when the material falls from the turntable 251, the material will fall between the guide plate 263 and the motorized roller 262, and the motorized roller 262 is squeezed and rotated to squeeze the material into a continuous sheet, and the material falls into the inside of the hopper 22 along the above-mentioned unloading channel, and the continuous sheets of plant source and animal source are mixed after entering the conveying mechanism 23 to realize the pre-mixing operation of the material, thereby reducing the mixing time of the subsequent fermentation tank 1.

[0055] Reference Fig. 9 , Fig.10On the basis of the above embodiments, considering that in the present invention, the feeding speeds of the turntable 251 of the two sub-hoppers 24 are different during the feeding process of different proportions, in order to adjust the position of the electric roller 262 according to the current rotation speed to ensure that the material can be extruded into a continuous sheet, two displacement mechanisms 27 are provided on both sides of the hopper 22 in the present invention, and the two displacement mechanisms 27 on each side are connected to the two adjacent brackets 261. The electric roller 262 is controlled to move horizontally to change the width of the unloading channel, that is, in the present invention, when the feeding speed of the turntable 251 is too fast, the width of the unloading channel becomes larger to ensure the continuous passage of the material. Conversely, when the unloading speed of the turntable 251 is relatively low, the width of the unloading channel is reduced to ensure continuous extrusion of less material to form a thinner sheet structure to ensure continuous feeding of the material.

[0056] Specifically, the displacement mechanism 27 of the present invention includes a rotating shaft 271 rotatably connected to the hopper 22, two swing arms 272 are rotatably connected to the rotating shaft 271, and the ends of the swing arms 272 are fixedly connected to gravity balls 273;

[0057] A swivel ring 274 is slidably connected to the outer side of the rotating shaft 271, and connecting rods 275 are pinned between the two sides of the swivel ring 274 and the two swing arms 272. A swivel sleeve 276 is rotatably connected to the outer side of the swivel ring 274, and a compression spring 277 is fixedly connected between the swivel sleeve 276 and the rotating shaft 271, and the swivel sleeve 276 is connected to the bracket 261 through a connecting rod 278.

[0058] Reference Fig. 9 Preferably, in order to realize the power transmission of the above-mentioned rotating shaft 271, the shaft end of the motor 253 in this embodiment passes through and extends to the outside of the distributing hopper 24, and pulleys are fixedly connected to the shaft end of the motor 253 and the outside of the rotating shaft 271. The three pulleys on the same side are transmitted through a synchronous belt 279. Of course, the transmission ratio between the pulleys can be adaptively modified according to the needs of technical personnel in the relevant field to ensure that the rotating shaft 271 can rotate quickly.

[0059] In summary, in the present invention, when the motor 253 controls the turntable 251 to rotate and load materials, the motor 253 drives the rotating shaft 271 to rotate synchronously through the pulley and the synchronous belt 279. When the rotating shaft 271 rotates, it drives the swing arm 272 to rotate. Since the end of the swing arm 272 is fixedly installed with a gravity ball 273, at a high speed, the gravity ball 273 will drive the swing arm 272 to rotate outward under the influence of centrifugal force. At this time, the swing arm 272 pulls the rotating sleeve 276 through the connecting rod 275 to move linearly. When the rotating sleeve 276 moves linearly, it drives the bracket 261 to move through the connecting rod 278, so as to adjust the linear position of the electric roller 262 to change the width of the unloading channel.

[0060] Specifically, when the rotation speed of the turntable 251 is low, the rotation speed of the rotating shaft 271 is also reduced. At this time, the centrifugal force of the gravity ball 273 is small, so the electric roller 262 will move toward the side of the guide plate 263 to achieve squeezing of less material into a thinner sheet structure, thereby ensuring the continuity of the material. On the contrary, when the feeding speed is too fast, the electric roller 262 moves away from the side of the guide plate 263. At this time, the width of the unloading channel becomes larger, and more material is squeezed into a thicker sheet structure, thereby avoiding the accumulation of materials and ensuring the continuity of materials. In the present invention, the moving position of the electric roller 262 is adaptively changed according to the feeding speed, thereby ensuring the continuous transportation of materials. At the same time, no manual adjustment is required, which increases the convenience of operation.

[0061] Reference Fig.10 It should be noted that, in order to ensure that the brackets 261 on both sides of the electric roller 262 can move synchronously, so as to avoid the problem that the brackets 261 on both sides move asynchronously, causing the electric roller 262 to tilt and affecting the stability of material extrusion, a synchronization rod 264 is rotatably connected between the two brackets 261 on the same side in the present invention, and the ends of the two synchronization rods 264 are fixedly connected with gears 265, wherein a rack 266 meshing with the gear 265 is fixedly connected above the hopper 22, that is, in the present invention, when the centrifugal force is applied, the connecting rod 278 drives the bracket 261 to move, because the synchronization rod 264 is rotatably connected between the two brackets 261, the gears 265 at both ends of the synchronization rod 264 are meshed with the rack 266, so when one side is tilted, the positions of the two brackets 261 can be corrected by the meshing position of the gear 265 and the rack 266, so as to ensure that the two brackets 261 can move synchronously, so as to ensure the uniformity of the thickness of the material extrusion.

[0062] In summary, in the present invention, a feeding device 2 is arranged on one side of the fermentation tank 1. Since the feeding device 2 adopts the design of two sub-hoppers 24, the plant source and the animal source can be added separately at the same time. The feeding amount of the plant source and the animal source can be controlled by changing the rotation speed of the feeding mechanism 25, so as to achieve the purpose of adding in different proportions. Thereafter, the two materials are transported to the fermentation tank 1 by the conveying mechanism 23 to achieve the mixing and fermentation of the two materials. In addition, a leveling mechanism 26 is also provided in the present invention, which is used to extrude and level the material to ensure that the material can be continuously fed, and ensure that the conveying mechanism 23 can be pre-mixed during the process of feeding into the fermentation tank 1 to reduce the mixing time of the fermentation tank 1. The overall structure is novel, which greatly improves the convenience and efficiency of the fermentation operation.

[0063] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
