Abstract
Description
Technical Field
[0001] This utility model relates to the field of microbial fertilizer production technology, specifically to a fermentation device for microbial fertilizer. Background Technology
[0002] Microbial fertilizers are biological agents with active microorganisms as their core component. They improve plant nutrient supply or promote crop growth through the life activities of microorganisms, and are considered green agricultural inputs. Their essential characteristic lies in containing reproducing live microorganisms, distinguishing them from the mineral element properties of traditional chemical fertilizers.
[0003] For example, the authorization announcement number "CN213202866U" describes a fermentation device for microbial fertilizer, consisting of a fermentation tank and an oxygen tank. A motor-driven rotating shaft drives a stirring rod and scraper to achieve uniform stirring. Combined with a connecting pipe and an oxygen supply pipe with oxygen supply holes, it forms a controllable oxygen supply system. It features a compact structure, precise oxygen supply, and high fermentation efficiency. However, existing fermentation devices for microbial fertilizer require fermentation to be completed inside the fermentation tank. The raw materials for microbial fertilizer are mainly decomposed organic fertilizer mixed with straw, sawdust, and other materials. The resulting microbial fertilizer is a semi-solid, viscous substance. Therefore, fermentation in a mixing tank is cumbersome for both material removal and discharge, easily clogging the inlet and outlet. Furthermore, frequent ventilation is required during the fermentation process to prevent foul odors. The anaerobic, sealed environment inside the fermentation tank hinders air circulation, affecting the final fermentation effect of the microbial fertilizer.
[0004] Furthermore, conventional microbial fertilizer fermentation devices require the medium mixed with microbial liquid to be laid in the fermentation container, and a waterproof plastic sheet needs to be laid on top of the fermentation container. This can reduce the impact of external rainwater mixed with bacteria on the microbial fermentation environment. However, for large-volume fermentation containers, laying and removing the plastic sheet on top is more troublesome and requires multiple workers. At the same time, if the plastic sheet is not laid flat enough, it is easy to accumulate rainwater and cause it to collapse, affecting the rainproof effect of the microbial fertilizer fermentation device. Utility Model Content
[0005] The purpose of this invention is to solve the problems of poor fermentation effect and weak rain protection of existing microbial fertilizer fermentation devices, and to propose a microbial fertilizer fermentation device.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] Design a fermentation device for microbial fertilizer, including a fermentation tank, columns and closing doors. Multiple closing doors are movably connected to the front end of the fermentation tank, and multiple columns are fixedly installed at the bottom end of the fermentation tank. The inner side of the fermentation tank is provided with a semi-open microbial fertilizer stacking structure, one side of the outer wall of the fermentation tank is provided with a rainproof plastic sheet quick-covering structure, and the top of the fermentation tank is provided with a fermentation solution spraying structure.
[0008] Preferably, the semi-open microbial fertilizer stacking structure includes fixed plates and connecting shafts. Multiple connecting shafts are rotatably installed on both sides of the inner wall of the fermentation tank. The outer sides of the multiple connecting shafts are fixedly connected to the side wall of the closed door. Multiple fixed plates are fixedly installed on the front end of the outer wall of the fermentation tank. Threaded rods are threadedly connected to the inner sides of the multiple fixed plates. Ventilation holes are fixedly opened on the outer walls of the multiple closed doors. Heating pipes are fixedly installed on the inner walls of the multiple closed doors.
[0009] Preferably, the ends of the plurality of threaded rods abut against the outer wall of the closed door, and the plurality of vent holes are distributed parallel to each other at equal intervals.
[0010] Preferably, the quick-laying structure for the rainproof plastic sheet includes a fixed side plate and a pressure rod. The fixed side plate is fixedly installed on one side of the outer wall of the fermentation tank. An extension block is fixedly connected to the outer wall of the fixed side plate. A winding drum is rotatably installed on the inner side of the extension block via a bearing. A motor is fixedly installed on the outer wall of the extension block. The rainproof plastic sheet is movably wound around the outer side of the winding drum. The other end of the rainproof plastic sheet is fixedly connected to the pressure rod.
[0011] Preferably, the output shaft of the motor is fixedly connected to one end of the winding drum, and the inner wall of the plastic rainproof cloth is close to the top of the fermentation box.
[0012] Preferably, the fermentation solution spraying structure includes vertical plates and a spray frame. Multiple vertical plates are fixedly installed on the top of the outer wall of the fermentation tank. A horizontal plate is fixedly connected above the multiple vertical plates. A spray frame is fixedly installed at the lower end of the horizontal plate. A connecting pipe is fixedly connected to the bottom end of the spray frame. Multiple nozzles are fixedly connected below the connecting pipe. The rear side of the connecting pipe is connected to an external pump.
[0013] The present invention proposes a fermentation device for microbial fertilizer, which has the following advantages: the fermentation chamber space inside the closed door can hold straw compost and other materials containing microorganisms; the microbial fertilizer is fermented using natural compost; the ventilation holes ensure ventilation during the fermentation process, reducing odor generation and accelerating microbial activity; the method of fermentation using natural compost does not require stirring or turning, ensuring ventilation while quickly achieving microbial fertilizer fermentation, thus improving the fermentation effect of the fermentation device for microbial fertilizer.
[0014] When the microbial solution needs to be sprayed, the rainproof plastic sheet is retracted. After spraying, the operator can use the pressure bar to pull out the rainproof plastic sheet and lay it flat on top of the fermentation tank. The pressure bar is made of a solid metal bar with a certain weight. The pressure bar sinks down to stretch the rainproof plastic sheet flat. When rolling it up, simply start the motor. The motor drives the winding drum on the extension block to rotate. The winding drum can quickly roll up the rainproof plastic sheet using mechanical force. This can reduce rainwater damage to the microbial fertilizer fermentation environment, save operators time in rolling up the plastic sheet, and improve the rainproof effect of the fermentation device for microbial fertilizer.

[0022] The present invention will be further described below with reference to the accompanying drawings:
[0023] Example 1:

The top of the fermentation box 1 is provided with a fermentation solution spraying structure 6.
[0025] The semi-open microbial fertilizer stacking structure 5 includes a fixing plate 51 and connecting shafts 54. Multiple connecting shafts 54 are rotatably installed on both sides of the inner wall of the fermentation tank 1. The connecting shafts 54 facilitate the opening and closing of the closing door 3 at the front end of the fermentation tank 1. When the closing door 3 is vertically closed, the threaded rod 52 can be horizontally screwed into the inside of the fixing plate 51, thus preventing the closing door 3 from opening. The outer sides of the multiple connecting shafts 54 are fixedly connected to the side wall of the closing door 3. The multiple fixing plates 51 are fixedly installed on the front end of the outer wall of the fermentation tank 1, thus preventing the closing door 3 from opening. The fermentation chamber 1 can hold straw compost and other materials containing microorganisms. Microbial fertilizer is produced by composting natural compost. Threaded rods 52 are threaded to the inner sides of multiple fixed plates 51. Ventilation holes 55 are fixedly opened on the outer walls of multiple closed doors 3. Ventilation holes 55 can ensure ventilation during the composting process, reduce odor generation, and accelerate microbial activity. Heating tubes 53 are fixedly installed on the inner walls of multiple closed doors 3. The heating tubes 53 are connected to the power supply via guides. When the heating tubes 53 are connected to the circuit, they will generate a certain amount of heat, which helps to create a temperature conducive to microbial activity.
[0026] The connecting shaft 54 facilitates the opening and closing of the door 3 at the front end of the fermentation chamber 1 by flipping it open or closing it vertically. When the door 3 is closed vertically, the threaded rod 52 can be screwed horizontally into the inside of the fixing plate 51. This way, the threaded rod 52 can hold the door 3 in place. The space inside the fermentation chamber 1 with the door 3 can hold straw compost and other materials containing microorganisms. Microbial fertilizer is made by composting natural compost. The inner threads of multiple fixing plates 51 are connected to threaded rods 52. The ventilation holes 55 can ensure ventilation during the composting process, reduce odor generation, and accelerate microbial activity. The heating tube 53 generates heat after the circuit is turned on, which creates a temperature conducive to microbial activity. The method of composting natural compost does not require stirring or turning, which can ensure ventilation and quickly achieve microbial fertilizer fermentation, thus improving the fermentation effect of the microbial fertilizer fermentation device.
[0027] The ends of multiple threaded rods 52 abut against the outer wall of the closing door 3, and multiple vent holes 55 are distributed parallel to each other at equal intervals.

A winding drum 44 is rotatably installed on the inner side of the extension block 42 via bearings. A motor 43 is fixedly installed on the outer wall of the extension block 42. The motor 43 is a servo motor. When selecting a servo motor, a motor model that meets the usage requirements can be selected. A plastic rainproof cloth 45 is movably wound around the outer side of the winding drum 44. The plastic rainproof cloth 45 is made of relatively thick polyvinyl chloride material. The rainproof plastic cloth 45 is normally rolled up on the outside of the winding drum 44. When it is necessary to spray microbial solution, the rainproof plastic cloth 45 is used. After the spraying is finished, the staff can use the pressure bar 46 to pull out the plastic rainproof cloth 45 and then lay it flat on the top of the fermentation box 1. The pressure bar 46 is made of a solid metal bar with a certain weight. The pressure bar 46 sinks down to stretch the rainproof plastic cloth 45 flat. When rolling it up, only the motor 43 needs to be started. The motor 43 drives the winding drum 44 to rotate on the extension block 42. The winding drum 44 can quickly roll up the plastic rainproof cloth 45 using mechanical force. The other end of the plastic rainproof cloth 45 is fixedly connected to the pressure bar 46. The output shaft of the motor 43 is fixedly connected to one end of the winding drum 44. The inner wall of the plastic rainproof cloth 45 is close to the top of the fermentation box 1.
[0029] When the microbial solution needs to be sprayed, the rainproof plastic sheet 45 is retracted. After spraying, the operator can use the pressure rod 46 to pull out the rainproof plastic sheet 45 and lay it flat on the top of the fermentation tank 1. The pressure rod 46 is made of a solid metal bar with a certain weight. The pressure rod 46 sinks down to stretch the rainproof plastic sheet 45 flat. When rolling it up, only the motor 43 needs to be started. The motor 43 drives the winding drum 44 to rotate on the extension block 42. The winding drum 44 can quickly roll up the rainproof plastic sheet 45 using mechanical force. This can reduce the damage of rainwater to the fermentation environment of microbial fertilizer, save the operator's time in rolling up the plastic sheet, and improve the rainproof effect of the fermentation device for microbial fertilizer.

When the plastic rainproof cloth 45 is retracted, the power supply is connected and the pump is started. The microbial solution can be sprayed along the multiple nozzles 65 at the lower end of the horizontal plate 62 onto the fertilizer accumulated inside the fermentation tank 1 to replenish the microorganisms and maintain their activity. Multiple nozzles 65 are fixedly connected to the lower part of the connecting pipe 64. The rear side of the connecting pipe 64 is connected to an external pump.
[0031] Working principle:
[0032] Microbial fertilizer fermentation equipment is used for the production and manufacturing of microbial fertilizers. It involves evenly spraying a microbial solution onto a pre-prepared structure or sawdust, and then fermenting the microbial fertilizer by adjusting the temperature, humidity and environment.
[0033] The stacked fermentation structure of a fermentation device for microbial fertilizers:
[0034] The connecting shaft 54 facilitates the opening and closing of the door 3 at the front of the fermentation chamber 1 by flipping it open or closing it vertically. When the door 3 is closed vertically, the threaded rod 52 can be screwed horizontally into the inside of the fixing plate 51. In this way, the threaded rod 52 can hold the door 3 in place. The space inside the fermentation chamber 1 with the door 3 can hold straw compost and other materials with added microorganisms. Microbial fertilizer is made by composting natural compost. The inner threads of multiple fixing plates 51 are connected to the threaded rod 52. The ventilation holes 55 can ensure ventilation during the composting of microbial fertilizer, reduce the generation of odors and accelerate the activity of microorganisms. The heating tube 53 generates a certain amount of heat after the circuit is turned on, which creates a temperature for the microorganisms to be active. The method of composting with natural compost does not require stirring or turning, and can ensure ventilation while quickly realizing the fermentation of microbial fertilizer.
[0035] Rainproof structure of fermentation device for microbial fertilizer:
[0036] An extension block 42 is fixedly connected to the outer wall of the fixed side plate 41. A winding drum 44 is rotatably installed on the inner side of the extension block 42 via a bearing. The plastic rainproof cloth 45 is made of relatively thick polyvinyl chloride material. The rainproof plastic cloth 45 is normally rolled up on the outside of the winding drum 44. When it is necessary to spray microbial solution, the rainproof plastic cloth 45 is rolled up. After spraying, the staff can use the pressure rod 46 to pull out the plastic rainproof cloth 45 and then lay it flat on the top of the fermentation tank 1. The pressure rod 46 is made of a solid metal bar with a certain weight. The pressure rod 46 sinks down to stretch the rainproof plastic cloth 45 flat. When winding, only the motor 43 needs to be started. The motor 43 drives the winding drum 44 to rotate on the extension block 42. The winding drum 44 can quickly wind up the plastic rainproof cloth 45 using mechanical force.
[0037] Microbial solution spraying structure for microbial fertilizer fermentation device:
[0038] Connecting pipe 64 connects the nozzles 65 at the lower end of the spray frame 63 to an external pump and microbial solution. Thus, when the plastic rainproof cloth 45 is retracted, connecting the power supply and starting the pump allows the microbial solution to be sprayed along the lower end of the horizontal plate 62 through multiple nozzles 65 onto the fertilizer accumulated inside the fermentation tank 1, replenishing the microorganisms and maintaining their activity. Although this utility model has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
