A device for preparing microbial agent for tomato cultivation

Abstract

The invention discloses a device for preparing a microbial inoculant for tomato cultivation, and relates to the technical field of fermentation equipment. The sealed fermentation and reproduction of microorganisms will generate a large amount of gas, so that the air pressure in a fermentation tank increases continuously with the increase of fermentation time. For the safety of fermentation, the excess gas needs to be discharged within a safe range. At the same time, during the exhaust process, the gas will drive debris to fly out together. After the gas is generated by fermentation in the fermentation tank and the internal air pressure increases, the air pressure pushes the sealing disk compression spring to deform. When the air pressure reaches a certain level and the sealing disk moves to the top of the air hole, the gas generated by the internal fermentation passes through the air hole, the air guide groove and the exhaust groove in sequence, and the gas generated by the fermentation is discharged. The air hole and the air guide groove are wrapped by a pipe cover, so that the gas passes through the air hole and enters a larger space, the flow speed is reduced, and the debris driven by the gas flow is blocked.

The top of the top cover is a downwardly inclined surface from the outside to the inside.

[0013] The present invention provides a device for preparing a microbial agent for tomato cultivation. It has the following beneficial effects:

[0014] 1. The device for preparing microbial inoculants for tomato cultivation cooperates with an exhaust pipe and a sealing plate. When the gas is produced by fermentation in the fermentation tank and the internal air pressure increases, the air pressure pushes the sealing plate compression spring to deform. When the air pressure reaches a certain level and the sealing plate moves above the air hole, the gas produced by the internal fermentation passes through the air hole, the air guide groove and the exhaust groove in sequence to discharge the gas produced by the fermentation. In the process of discharging the gas, the air hole and the air guide groove are wrapped by the pipe cover, so that the gas enters a larger space after passing through the air hole, reducing the flow speed. In the process of exhausting the gas, the pipe cover blocks the debris driven by the gas flow, and prevents the debris from flying out directly while stabilizing the air pressure within a safe range.

[0015] 2. The device for preparing microbial inoculants for tomato cultivation changes the positions of the spiral ring and the threaded tube so that the sealing disk is at the lowest position, adjusts the initial compression degree of the spring, and adjusts the sealing disk to reach the maximum air pressure above the air hole. During fermentation, the maximum air pressure of the exhaust can be adjusted according to the situation, thereby better ensuring the air pressure range in the fermentation tank.

[0016] 3. The device for preparing microbial inoculants for tomato cultivation can adjust the position of the stirring plate through the buoyancy of the hollow float when the liquid level in the fermentation tank is different. When there is more material in the fermentation tank, the stirring plate can reach a deeper position of the liquid in the fermentation tank, thereby better driving the material and improving the stirring effect.

[0017] Fourth, the device for preparing microbial inoculants for tomato cultivation uses a weighted ball to make the gas pressure greater than the sum of the liquid pressure in the tank and the gravity of the weighted ball before ventilation and stirring are carried out in the fermentation tank, so as to avoid low gas pressure, which causes the liquid to flow downward along the gas passage after the gas passage is opened. At the same time, the stirring wheel is driven to rotate in the process of the gas driving the material to surge upward, so that the stirring wheel cooperates with the stirring plate to stir and mix the material, thereby improving the uniformity of the material mixing.

[0018] 5. The device for preparing microbial agents for tomato cultivation, through the cooperation of the bottom cover and the top cover, in the process of gas driving the bottom material to surge upward, utilizes the upward inclined surface of the bottom of the bottom cover from the outside to the inside to make the bottom material surge upward from the center position, and cooperates with the floating stirring mechanism to make the material evenly diffused to the surroundings, so that the mixing between the materials is more uniform during the stirring process.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0030] The first embodiment, as Figure 1 to Figure 2 and Figures 5 to 7 As shown, the present invention provides a technical solution: a device for preparing a microbial agent for tomato cultivation, comprising:

[0031] A frame 1 having a frame supporting a structural component, and a heightened platform is provided on one side of the top of the frame 1, and a motor 7 is fixedly installed at the center of the top of the heightened platform, and an air compressor 6 is fixedly installed on the other side of the top of the frame 1;

[0034] An air stirring mechanism 4, which stirs the internal materials by introducing gas, and the air stirring mechanism 4 is installed at the bottom of the fermentation tank 5 and is connected to the air compressor 6 through a pipeline;

[0035] A flotation and stirring mechanism 3, which stirs the material by rotating, and the flotation and stirring mechanism 3 is installed inside the fermentation tank 5;

[0036] The exhaust mechanism 2 includes an exhaust pipe 22, the bottom end of the exhaust pipe 22 is fixedly connected to the fermentation tank 5, and a screw head 24 is fixedly installed on the top of the exhaust pipe 22, the exhaust pipe 22 is threadedly connected to a screw cover 23 through the screw head 24, a threaded pipe 25 is fixedly installed at the center of the inner wall of the screw cover 23, and air holes, air guide grooves and exhaust grooves are evenly opened on the outside of the exhaust pipe 22; and the air holes, air guide grooves and exhaust grooves are arranged in sequence from bottom to top, and a pipe cover 21 is fixedly installed on the outside of the exhaust pipe 22. When the pressure reaches a certain level, the sealing plate 26 moves to the exhaust Above the air hole of the tube 22, the gas inside the fermentation tank 5 enters between the pipe cover 21 and the exhaust pipe 22 through the air hole, and the gas enters the exhaust pipe 22 again through the air guide groove and is discharged through the exhaust groove, so that the air pressure inside the fermentation tank 5 is stabilized within a safe range, preventing the debris in the fermentation raw materials from flying out with the air flow during the fermentation process of the microbial agent required for the tomato crop, and at the same time preventing the high air pressure in the fermentation place from affecting the fermentation and reproduction speed of the microbial agent required for the tomato crop, and the air hole and the air guide groove are located on the inner side of the pipe cover 21.

[0037] A sealing disk 26 is slidably installed on the inner wall of the threaded tube 25 through a rod. The sealing disk 26 is located below the air hole. A thread is set on the top of the outer side of the threaded tube 25, and a spiral ring 27 is threadedly connected to the top of the outer side of the threaded tube 25. A fixing ring 28 is rotatably installed on the bottom of the spiral ring 27. After the material in the fermentation tank 5 is fermented, a large amount of gas is generated, which increases the air pressure inside the fermentation tank 5. After the air pressure increases, the exhaust pipe 22 is connected with the fermentation tank 5 to increase the air pressure in the air. The gas contacts the sealing disk 26, and in the process of increasing internal air pressure, the pressure on the sealing disk 26 is gradually increased, and the spring 29 is pressed by the sealing disk 26 to deform under pressure. In the process of deformation of the spring 29, the sealing disk 26 slides up along the inner wall of the threaded tube 25 under the connection of the rod. A spring 29 is fixedly installed between the fixing ring 28 and the sealing disk 26. The spring 29 is located on the outer side of the threaded tube 25, and there is a gap between the spiral ring 27 and the exhaust pipe 22.

[0038] The second embodiment is based on the first embodiment. Figure 3 to Figure 4As shown, the floating stirring mechanism 3 includes a connecting shaft 31, the top end of the connecting shaft 31 is connected to the output end of the motor 7 through a coupling, and the bottom of the outer side of the connecting shaft 31 is rotatably connected to the inner wall of the fermentation tank 5. The output end of the motor 7 drives the connecting shaft 31 to rotate. Through the restriction of the rotational connection between the connecting shaft 31 and the inner wall of the fermentation tank 5, the bottom end of the connecting shaft 31 drives the chute shaft 32 to rotate through the flange connection. During the rotation of the chute shaft 32, the rotating rod 33 rotatably connected in the chute drives the hollow floating ball 34 and the stirring plate 35 to rotate along the axial position of the chute shaft 32. The bottom end flange of the connecting shaft 31 is connected to the chute shaft 32, and the chute shaft 32 is symmetrically provided with chute grooves, and the chute of the chute shaft 32 is rotatably installed with a rotating rod 33, and one end of the rotating rod 33 is fixedly installed with a hollow floating ball 34, and the hollow floating ball 34 can be in the liquid. Floating, when the liquid level of the material inside the fermentation tank 5 is different, the buoyancy of the hollow float 34 in the liquid drives the rotating rod 33 to rotate at different angles. When the liquid is not in contact with the hollow float 34, the rotating rod 33 is perpendicular to the chute shaft 32. When there is a lot of material inside the fermentation tank 5, or water is produced during the fermentation process, the liquid level is raised, and the buoyancy drives the hollow float 34 to move upward, so that the rotating rod 33 rotates in the chute of the chute shaft 32, and the stirring plate 35 tilts downward. When there is a lot of material inside the fermentation tank 5, the stirring plate 35 can drive the material to rotate at a deeper position in the fermentation tank 5, so that the fermentation raw materials of the microbial inoculant required for the tomato crop are more fully driven and stirred, so that the raw materials are fully contacted and reacted, and the fermentation effect is improved. The stirring plate 35 is fixedly installed at one end of the rotating rod 33 away from the hollow float 34, and the stirring plate 35 does not contact the inner wall of the fermentation tank 5.

[0039] The third embodiment is based on the first and second embodiments. Figures 8 to 9As shown, the air stirring mechanism 4 includes an air guide cover 401, which is fixedly installed at the bottom of the fermentation tank 5, and a hole cover 408 is fixedly installed at the center of the bottom of the air guide cover 401, and the outer side of the hole cover 408 is evenly provided with air outlet holes, and a connecting plate 409 is fixedly installed at the bottom of the air guide cover 401. The bottom of the connecting plate 409 is connected with the air outlet end of the air compressor 6 through a pipeline, and a hole plate 407 is fixedly installed on the top of the hole cover 408. The top of the hole plate 407 is provided with an annular groove, and circular grooves are evenly provided in the annular groove. The air is compressed by the air compressor 6 to make the air become high-pressure gas, which is introduced into the interior of the hole cover 408 through the pipeline and passes through the hole cover 40 8, the gas is discharged, and the gas is accumulated between the air guide cover 401 and the hole plate 407. During the accumulation process, the air pressure is continuously increased. After the air pressure is greater than the sum of the hydraulic pressure inside the fermentation tank 5 and the gravity of the counterweight ball 406, the gas passes through the circular groove of the hole plate 407 and the through hole of the hole ring 410, and pushes the pressure ring 405, so that the pressure ring 405 drives the connecting rod 403, the counterweight ball 406 and the stirring wheel 404 to move upward, and the gas flow pipeline is opened, so that the gas enters from the bottom of the fermentation tank 5, and drives the material to surge upward. The hole ring 410 is fixedly installed in the annular groove of the hole plate 407, and the top of the hole ring 410 is evenly opened with through holes, and the positions of the through holes and the circular grooves correspond one to one.

[0040] A connecting rod 403 is slidably installed on the inner wall of the hole ring 410, and a counterweight ball 406 is fixedly installed on the bottom end of the connecting rod 403, and a pressure ring 405 is fixedly installed at the central position of the outer side of the connecting rod 403, and the pressure ring 405 is located above the hole ring 410, and the pressure ring 405 corresponds to the through hole one by one, and a stirring wheel 404 is rotatably installed on the top of the outer side of the pressure ring 405, and a bottom cover 411 is fixedly installed on the top of the inner wall of the air guide cover 401, and a top cover 402 is fixedly installed on the top of the bottom cover 411, and the bottom of the bottom cover 411 is an upward inclined surface from the outside to the inside. While surging, the airflow drives the material to flow, so that the stirring wheel 404 rotates, and in the process of upward surging, the inclined surface at the bottom of the bottom cover 411 cooperates with the airflow, so that the bottom material moves to the center position during the upward surging process, so that the material in the fermentation tank 5 is driven to surge upward and then diffuses to the surroundings, and the top of the top cover 402 is a downward inclined surface from the outside to the inside.

[0041] During use, a worker puts the microbial agent material into the fermentation tank 5 from the material inlet, and starts the air compressor 6 and the motor 7, so that the air compressor 6 and the motor 7 respectively drive the air stirring mechanism 4 and the floating stirring mechanism 3, so that the floating stirring mechanism 3 cooperates with the air stirring mechanism 4 to stir and mix the materials in the fermentation tank 5, so that the materials in the fermentation tank 5 are evenly distributed, and then the stirring is stopped to ferment the materials in the fermentation tank 5. A large amount of gas is generated during the fermentation process, and the internal air pressure of the fermentation tank 5 increases. The gas generated by the internal fermentation is discharged through the exhaust mechanism 2, so that the internal air pressure of the fermentation tank 5 is maintained within a safe range.

[0042] In the process of stirring by the floating stirring mechanism 3 cooperating with the air stirring mechanism 4, the output end of the motor 7 drives the connecting shaft 31 to rotate, and through the restriction of the rotational connection between the connecting shaft 31 and the inner wall of the fermentation tank 5, the bottom end of the connecting shaft 31 drives the chute shaft 32 to rotate through the flange connection. In the process of the rotation of the chute shaft 32, the rotating rod 33 connected to the chute is driven by the rotating rod 33 to rotate along the axial position of the chute shaft 32, and when the liquid level of the material inside the fermentation tank 5 is different The buoyancy of the hollow float 34 in the liquid drives the rotating rod 33 to rotate at different angles. When the liquid is not in contact with the hollow float 34, the rotating rod 33 is perpendicular to the chute shaft 32. When there is a lot of material inside the fermentation tank 5, or water is produced during the fermentation process, the liquid level rises, and the buoyancy drives the hollow float 34 to move upward, causing the rotating rod 33 to rotate in the chute of the chute shaft 32, causing the stirring plate 35 to tilt downward. When there is a lot of material inside the fermentation tank 5, the stirring plate 35 can drive the material to rotate at a deeper position inside the fermentation tank 5.

[0043] In the process of stirring the material by the air stirring mechanism 4, the air is compressed by the air compressor 6 to become high-pressure gas, which is introduced into the interior of the hole cover 408 through the pipeline, and the gas is discharged through the air outlet of the hole cover 408, so that the gas accumulates between the wind guide cover 401 and the hole plate 407. In the process of accumulation, the air pressure is continuously increased. After the air pressure is greater than the sum of the hydraulic pressure inside the fermentation tank 5 and the gravity of the counterweight ball 406, the gas passes through the circular groove of the hole plate 407 and the through hole of the hole ring 410, pushing the pressure ring 405, so that the pressure ring 405 drives the connecting rod 403, the counterweight ball 406 and the stirring wheel 404 to move upward, opening the gas circulation pipeline, allowing the gas to enter from the bottom of the fermentation tank 5, driving the material to surge upward, and at the same time as the surge, the air flow drives the material to flow, so that the stirring wheel 404 rotates, and in the process of upward surge, the inclined surface at the bottom of the bottom cover 411 cooperates with the air flow to make the bottom material move to the center position during the upward surge, so that the material in the fermentation tank 5 is driven to surge upward and then diffuse to the surroundings.

[0044] After the material in the fermentation tank 5 is fermented, a large amount of gas is generated, which increases the air pressure inside the fermentation tank 5. After the air pressure increases, the exhaust pipe 22 is connected to the fermentation tank 5 to increase the air pressure in the air. The gas contacts the sealing disk 26, and in the process of increasing internal air pressure, the pressure on the sealing disk 26 is gradually increased, and the spring 29 is pressed by the sealing disk 26, so that the spring 29 is deformed under pressure. In the process of deformation of the spring 29, the sealing disk 26 slides upward along the inner wall of the threaded tube 25 under the connection of the rod. When the pressure reaches a certain level, the sealing disk 26 moves to the top of the air hole of the exhaust pipe 22, so that the gas inside the fermentation tank 5 enters between the pipe cover 21 and the exhaust pipe 22 through the air hole, so that the gas enters the exhaust pipe 22 again through the air guide groove, and is discharged through the exhaust groove, so that the air pressure inside the fermentation tank 5 is stabilized within a safe range.

[0045] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
