A constant-temperature fermentation reaction device special for bio-herbicide

Abstract

The application discloses a constant-temperature fermentation reaction device special for biological herbicides, which comprises a shell, a fermentation cavity, a hollow cavity, a supporting plate, a supporting rod, a transverse plate, a feeding pipe, a raw material box, a baffle, a rotating shaft, a stirring rod, an oxygen bin, a conveying bin, a pressing plate, a gas conveying assembly and a closing assembly. When working, the raw material enters the fermentation cavity through the feeding pipe after opening the valve of the feeding pipe. After the double-shaft motor is started, the second driving shaft drives the conveying rod and the feeding blade to continuously push the raw material through the connecting mechanism. The first driving shaft drives the rotating shaft and the stirring rod to stir and mix the raw material through the cross strip and the cross cavity. Meanwhile, the gas conveying assembly is driven by the connecting unit to pass the oxygen in the oxygen bin into the fermentation cavity. The raw material continuously enters the fermentation cavity, so that the supporting plate moves downward. When the supporting plate moves to the set position, the limiting column presses the emergency stop button to cut off the power supply of the motor. The stirring and oxygen supply are synchronously stopped. Meanwhile, the transverse plate moves downward to drive the closing assembly to tighten the pull rope through the winding drum, drive the baffle to close the outlet of the feeding pipe, and seal the fermentation cavity to enter the constant-temperature standing stage.

Description

Technical Field

[0001] This invention relates to a fermentation reaction device, specifically a constant temperature fermentation reaction device for biological herbicides. Background Technology

[0002] Biological herbicides are a new type of environmentally friendly pesticide that uses microorganisms or their metabolites to inhibit or kill weeds. The production process requires a constant-temperature fermentation stage, and the quality of fermentation directly affects the final product's weed-controlling effect. Existing fermentation reactors typically use independent motors to control stirring and oxygen supply, resulting in complex structures, high energy consumption, and reliance on manual valve control during feeding. This makes it difficult to precisely control the amount of raw materials used in each fermentation, easily leading to overfeeding or underfeeding, and inconsistent fermentation results.

[0003] Meanwhile, existing devices lack an automatic sealing mechanism at the bottom of the feed pipe during the fermentation settling stage, which easily leads to raw material leakage or external impurities entering the fermentation chamber, disrupting the fermentation environment. Furthermore, traditional devices require manual intervention to stop stirring and oxygen supply after feeding, resulting in low automation, cumbersome operation, and low production efficiency. Therefore, there is an urgent need for a constant-temperature fermentation reactor that can automatically control the feed rate, synchronously drive stirring and oxygen supply, and automatically seal the fermentation chamber after feeding to improve the fermentation quality and production efficiency of biological herbicides.

[0008] As a further aspect of the present invention: the driving assembly includes a dual-axis motor, which is mounted on the bottom wall of the raw material box. A first drive shaft and a second drive shaft are mounted on the output end of the dual-axis motor. The end of the first drive shaft away from the dual-axis motor extends into the fermentation chamber. A limit post is installed on the bottom wall of the fermentation chamber, and an emergency stop button is installed on the limit post.

The first drive shaft and the rotating shaft are movably connected through the cooperation of the cross bar and the cross cavity.

[0010] As a further embodiment of the present invention: the gas delivery assembly includes a driven shaft, which is rotatably mounted on the housing. A disc is mounted on the end of the driven shaft away from the housing. A guide plate is mounted on one side of the disc. Limiting grooves are symmetrically installed on the top wall of the housing.

[0012] As a further aspect of the present invention, the elastic component is a spring.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention utilizes a pallet that slides downwards along the inner wall of the fermentation chamber under the weight of the raw materials. When the pallet reaches a set position, the limit post on the support rod presses the emergency stop button, which cuts off the power to the dual-axis motor, thus achieving synchronous and automatic stopping of feeding and oxygen supply. This eliminates the need for manual judgment of whether the fermentation chamber is full, ensuring consistent raw material quantity and oxygen supply for each fermentation, thereby improving the stability of fermentation quality.

[0015] This invention utilizes a closing assembly at the bottom of a horizontal plate. As the horizontal plate moves downward with the support plate, the connecting rod pushes the connecting block to slide. The connecting block, through a fixed rod, drives the toothed plate to slide. The toothed plate meshes with the driven gear to drive the drum to rotate. The drum tightens the pull rope, pulling the baffle to slide, gradually blocking the material drop hole on the baffle until the bottom outlet of the feed pipe is completely sealed. This achieves automatic sealing of the bottom of the feed pipe, preventing raw material leakage or the entry of external impurities during fermentation, and ensuring the airtightness of the fermentation chamber.

[0016] This invention employs a dual-shaft motor to simultaneously drive the transmission assembly and the gas delivery assembly. The first drive shaft drives the rotating shaft and stirring rod to rotate through the cooperation of the cross bar and the cross cavity. At the same time, it drives the driven shaft and the gas delivery assembly to introduce oxygen into the fermentation chamber through the connecting unit. The second drive shaft drives the conveying rod and the feeding blade to transport raw materials through the connecting mechanism. A single motor realizes the synchronous drive of stirring, oxygen supply and feeding. The structure is compact and reduces energy consumption and equipment costs.

[0017] The present invention has one-way valves installed on both the delivery pipe and the connecting pipe to ensure that oxygen can only flow from the oxygen chamber to the fermentation chamber in one direction, preventing backflow and avoiding oxygen waste and pollution of the fermentation environment.

[0018] In the closure assembly of this invention, the elastic component is compressed and stores energy when the horizontal plate descends. After fermentation, the elastic component releases its elastic potential energy to assist the connecting block in resetting, thereby realizing the automatic switching between feeding closure and discharging opening, which facilitates discharging operation.

[0019] This invention integrates feed rate control, stirring and oxygen supply, and feed pipe sealing into a single system through mechanical linkage. A single action of the pallet descending can simultaneously trigger the stop motor and seal the feed inlet, reducing control links, lowering the failure rate, and improving the automation level and operational reliability of the device.

The connecting pipe 29 is located away from the conveying chamber. One end of the 4 extends into the fermentation chamber 5 and is connected to the gas outlet 30. One-way valves are installed on both the conveying pipe 37 and the connecting pipe 29. A drive assembly is installed on the housing 1, and a transmission assembly and a gas delivery assembly are connected to the drive assembly. The end of the transmission assembly away from the drive assembly is connected to the rotating shaft 46, and the end of the gas delivery assembly away from the drive assembly is connected to the extrusion plate 36. A closing assembly is installed at the bottom of the horizontal plate 10, and the end of the closing assembly away from the horizontal plate 10 is connected to the baffle 24.

A connecting block 14 is slidably installed in the hollow cavity 6, and a connecting rod 11 is hinged to the connecting block 14. The end of the connecting rod 11 away from the connecting block 14 is connected to the bottom of the horizontal plate 10. The wall is hinged, and an elastic component 15 is installed on the side wall of the connecting block 14. The end of the elastic component 15 away from the connecting block 14 is connected to the side wall of the sliding groove. A transverse groove is opened on one side of the sliding groove, and a toothed plate 16 is slidably installed in the transverse groove. A fixing rod is installed on the connecting block 14, and the end of the fixing rod away from the connecting block 14 is fixedly connected to the side wall of the toothed plate 16.

The end of the pull rope 13 away from the drum 18 passes through the side wall of the central cavity and is connected to the baffle 24. The pull rope 13 is also wrapped around the guide roller 12.

[0031] In this embodiment, during operation, the valve on the feed pipe 22 is first opened, and the raw materials in the raw material box 3 enter the fermentation chamber 5 through the feed pipe 22 under the action of gravity. Meanwhile, the drive assembly installed on the bottom wall of the raw material box 3 operates, driving the gas delivery assembly and the transmission assembly to operate. The raw material enters the fermentation chamber 5 through the material drop hole 25 on the bottom baffle 24 of the feed pipe 22. The transmission assembly drives the rotating shaft 46 to rotate, and several stirring rods 19 on the rotating shaft 46 rotate accordingly, continuously stirring and mixing the raw material in the fermentation chamber 5. The gas delivery assembly pushes the extrusion plate 36 in the conveying chamber 4 to slide towards the conveying pipe 37 through the pull rod 35, pressing the oxygen in the oxygen chamber 2 into the conveying chamber 4 through the conveying pipe 37, and then into the fermentation chamber 5 through the connecting pipe 29 and the gas outlet 30. The one-way valves on the conveying pipe 37 and the connecting pipe 29 ensure that the oxygen can only flow from the oxygen chamber 2 to the fermentation chamber 5 in one direction. As the raw material continuously enters the fermentation chamber 5, the support plate 7 slides down along the inner wall of the fermentation chamber 5 under the action of the weight of the raw material. The support rod 8 at the bottom of the support plate 7 drives the horizontal plate 10 to move down synchronously. When the pallet 7 descends to the set position, the drive assembly stops operating, and the oxygen supply stops. At the same time, as the horizontal plate 10 moves downward, the connecting rod 11 pushes the connecting block 14 to slide in the sliding groove of the hollow cavity 6. The elastic component 15 on the side wall of the connecting block 14 is compressed and stores energy. The connecting block 14 drives the toothed plate 16 to slide in the horizontal groove through the fixed rod. The toothed plate 16 meshes with the driven gear 17, driving the driven gear 17 and the rotating shaft to rotate. The rotating shaft drives the drum 18 to rotate, and the drum 18 tightens the pull rope 13. The pull rope 13 passes around the guide roller 12 on the side wall of the hollow cavity 6 and then pulls the baffle 24 to slide towards the bottom of the feed pipe 22. The material drop hole 25 on the baffle 24 is gradually blocked until the bottom outlet of the feed pipe 22 is completely sealed, realizing the automatic sealing of the feed pipe 22. At this time, the amount of raw material in the fermentation chamber 5 reaches the maximum value, and feeding and oxygen supply stop at the same time. The bottom of the feed pipe 22 is completely sealed by the baffle 24, the fermentation chamber 5 is sealed, and the fermentation process enters the constant temperature static stage.

[0032] Furthermore, the elastic component 15 can be a spring or an elastic sheet, etc., which will not be described in detail here.

[0033] Please see Figures 1 to 8As an embodiment of the present invention, the drive assembly includes a dual-axis motor 20, which is mounted on the bottom wall of the raw material box 3. A first drive shaft 21 and a second drive shaft 41 are mounted on the output end of the dual-axis motor 20. The end of the first drive shaft 21 away from the dual-axis motor 20 extends into the fermentation chamber 5. A limit post is mounted on the bottom wall of the fermentation chamber 5, and an emergency stop button 9 is mounted on the limit post. The emergency stop button 9 is electrically connected to the dual-axis motor 20. The transmission assembly includes a cross cavity 47. A cross cavity 47 is formed on the rotating shaft 46. The end of the first drive shaft 21 away from the dual-axis motor 20 extends into the cross cavity 47, and a cross bar 23 is mounted on the first drive shaft 21. The first drive shaft 21 and the rotating shaft 46 are movably connected through the cooperation of the cross bar 23 and the cross cavity 47. The gas conveying assembly includes a driven shaft 38, which is rotatably mounted on the housing 1. A disc 39 is mounted on the end of the driven shaft 38 away from the housing 1, and a guide is mounted on one side of the disc. Plate 31, the top wall of the housing 1 is symmetrically equipped with limit grooves, limit blocks 34 are slidably installed in the limit grooves, limit rods 33 are installed on the limit blocks 34, the end of the limit rods 33 away from the limit blocks 34 is connected to the guide plate 31, the guide plate 31 is provided with a guide groove, the disc 39 is eccentrically mounted with a guide rod 32, the end of the guide rod 32 away from the disc 39 extends into the guide groove, a pull rod 35 is installed on one side of the guide plate 31, the end of the pull rod 35 away from the guide plate 31 is connected to the extrusion plate 36, the first drive A connecting unit 40 is installed on the driving shaft 21. The end of the connecting unit 40 away from the first driving shaft 21 is connected to the driven shaft 38. A conveying rod 42 is symmetrically and rotatably installed on the raw material box 3. One end of the conveying rod 42 extends through the top wall of the raw material box 3 into the feed pipe 22. The feed pipe 22 is provided with a feeding blade 45, which is installed on the conveying rod 42. A connecting mechanism 43 is installed on the second driving shaft 41. The end of the connecting mechanism 43 away from the second driving shaft 41 is connected to the conveying rod 42.

[0034] In this embodiment, during operation, the valve on the feed pipe 22 is first opened, and the raw materials in the raw material box 3 enter the fermentation chamber 5 through the feed pipe 22 under the action of gravity. At the same time, the dual-shaft motor 20 installed on the bottom wall of the raw material box 3 is started, and the first drive shaft 21 and the second drive shaft 41 start to rotate simultaneously. The second drive shaft 41 drives the conveying rod 42 in the raw material box 3 to rotate through the connecting mechanism 43. One end of the conveying rod 42 extends into the feed pipe 22, and the feeding blade 45 on the conveying rod 42 rotates accordingly, continuously pushing the raw material in the raw material box 3 into the feed pipe 22. The raw material enters the fermentation chamber 5 through the drop hole 25 opened on the bottom baffle 24 of the feed pipe 22. The first drive shaft 21 extends into the fermentation chamber 5, and the cross bar 23 at its end is inserted into the cross cavity 47 on the rotating shaft 46. When the first drive shaft 21 rotates, the cross bar 23 and the cross cavity 47 cooperate to drive the rotating shaft 46 to rotate. Several stirring rods 19 on the rotating shaft 46 rotate accordingly, continuously stirring and mixing the raw material in the fermentation chamber 5, so that the raw material is in uniform contact. The connecting unit 40 on the first drive shaft 21 drives the driven shaft 38 to rotate, and the disc 39 at the end of the driven shaft 38 rotates accordingly. The guide rod 32, eccentrically mounted on the disc 39, reciprocates in the guide groove of the guide plate 31, pushing the guide plate 31 to slide in the limiting groove. The guide plate 31 pushes the extrusion plate 36 in the conveying chamber 4 to slide towards the conveying pipe 37 via the pull rod 35, forcing oxygen from the oxygen chamber 2 into the conveying chamber 4 via the conveying pipe 37, and then into the fermentation chamber 5 through the connecting pipe 29 and the gas outlet 30 to provide oxygen for fermentation. The one-way valves on the conveying pipe 37 and the connecting pipe 29 ensure that oxygen can only flow from the oxygen chamber 2 to the fermentation chamber 5 and will not flow back. As raw materials continuously enter the fermentation chamber 5, the support plate 7 slides downward along the inner wall of the fermentation chamber 5 under the action of the weight of the raw materials, and the support rod 8 at the bottom of the support plate 7 drives the horizontal plate 10 to move downward synchronously. When the horizontal plate 10 moves downward, it pushes the connecting block 14 to slide in the sliding groove of the hollow cavity 6 through the hinged connecting rod 11, and the elastic component 15 on the side wall of the connecting block 14 is compressed and stores energy. The connecting block 14 drives the toothed plate 16 to slide in the transverse groove via the fixed rod. The toothed plate 16 meshes with the driven gear 17, driving the driven gear 17 and the rotating shaft to rotate. The rotating shaft drives the drum 18 to rotate, and the drum 18 tightens the pull rope 13. The pull rope 13 passes around the guide roller 12 on the side wall of the hollow cavity 6 and then pulls the baffle 24 to slide towards the bottom of the feed pipe 22. The material drop hole 25 on the baffle 24 is gradually blocked until the bottom outlet of the feed pipe 22 is completely closed. At the same time, the support plate 7 continues to move downward, and the limiting post on the support rod 8 presses the emergency stop button 9 on the bottom wall of the fermentation chamber 5. The emergency stop button 9 cuts off the power to the dual-axis motor 20, and the motor immediately stops running. After the motor stops, the second drive shaft 41 stops rotating, the connecting mechanism 43 stops working, the conveying rod 42 and the feeding blade 45 stop rotating, and the raw material stops entering the feed pipe 22.The first drive shaft 21 stops rotating, the stirring rod 19 stops stirring, the driven shaft 38 stops rotating, the extrusion plate 36 resets, and the oxygen supply stops. At this time, the amount of raw material in the fermentation chamber 5 reaches its maximum value, feeding and oxygen supply stop simultaneously, the bottom of the feed pipe 22 is completely sealed by the baffle 24, the fermentation chamber 5 is sealed, and the fermentation process enters the constant temperature static stage.

[0035] Furthermore, both the connecting unit 40 and the connecting mechanism 43 can be gear sets or pulley sets, etc., which will not be described in detail here.

[0036] The working principle of this invention is as follows: During operation, the valve on the feed pipe 22 is first opened, and the raw materials in the raw material tank 3 are conveyed into the fermentation chamber 5 under gravity through the feed pipe 22. Simultaneously, the dual-shaft motor 20 installed on the bottom wall of the raw material tank 3 is started, and the first drive shaft 21 and the second drive shaft 41 begin to rotate simultaneously. The second drive shaft 41 drives the conveying rod 42 in the raw material tank 3 to rotate through the connecting mechanism 43. One end of the conveying rod 42 extends into the feed pipe 22, and the feeding blades 45 on the conveying rod 42 rotate accordingly, continuously pushing the raw materials in the raw material tank 3 into the feed pipe 22. The raw materials enter the fermentation chamber 5 through the discharge hole 25 on the bottom baffle 24 of the feed pipe 22. The first drive shaft 21 simultaneously performs both stirring and oxygen supply tasks. The first drive shaft 21 extends into the fermentation chamber 5, and the cross bar 23 at its end is inserted into the cross cavity 47 on the rotating shaft 46. When the first drive shaft 21 rotates, the cross bar 23 and the cross cavity 47 work together to drive the rotating shaft 46 to rotate. Several stirring rods 19 on the rotating shaft 46 rotate accordingly, continuously stirring and mixing the raw materials in the fermentation chamber 5. At the same time, the connecting unit 40 on the first drive shaft 21 drives the driven shaft 38 to rotate. The disc 39 at the end of the driven shaft 38 rotates accordingly. The guide rod 32 eccentrically mounted on the disc 39 reciprocates in the guide groove of the guide plate 31, pushing the guide plate 31 to slide in the limiting groove. The guide plate 31 pushes the extrusion plate 36 in the conveying chamber 4 to slide towards the conveying pipe 37 through the pull rod 35, forcing the oxygen in the oxygen chamber 2 into the conveying chamber 4 through the conveying pipe 37, and then into the fermentation chamber 5 through the connecting pipe 29 and the gas outlet 30. The one-way valves on the conveying pipe 37 and the connecting pipe 29 ensure that the oxygen can only flow from the oxygen chamber 2 to the fermentation chamber 5 in one direction. As raw materials continuously enter the fermentation chamber 5, the tray 7 slides downward along the inner wall of the fermentation chamber 5 under the action of gravity. The support rod 8 at the bottom of the tray 7 drives the horizontal plate 10 to move downward synchronously. When the horizontal plate 10 moves downward, it pushes the connecting block 14 to slide in the sliding groove of the hollow cavity 6 through the hinged connecting rod 11. The elastic component 15 on the side wall of the connecting block 14 is compressed and stores energy. The connecting block 14 drives the toothed plate 16 to slide in the horizontal groove through the fixed rod. The toothed plate 16 meshes with the driven gear 17, driving the driven gear 17 and the rotating shaft to rotate. The rotating shaft drives the drum 18 to rotate. The drum 18 tightens the pull rope 13. After the pull rope 13 passes around the guide roller 12, it pulls the baffle 24 to slide towards the bottom of the feed pipe 22. The discharge hole 25 on the baffle 24 is gradually blocked until the bottom outlet of the feed pipe 22 is completely closed. Meanwhile, the tray 7 continues to move downwards, and the limiting post on the support rod 8 presses the emergency stop button 9 on the bottom wall of the fermentation chamber 5. The emergency stop button 9 cuts off the power to the dual-shaft motor 20, and the motor immediately stops running. After the motor stops, stirring stops, oxygen supply stops, and feeding stops. At this time, the amount of raw material in the fermentation chamber 5 reaches its maximum value, the bottom of the feed pipe 22 is completely sealed, the fermentation chamber 5 is sealed, and the fermentation process enters the constant temperature static stage.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
