Description

Technical Field

[0001] The invention relates to the technical field of microbial agent preparation equipment, and in particular to a microbial agent preparation device for improving soil. Background Art

[0002] With the rapid development of modern agriculture, soil quality plays a decisive role in the growth and yield of crops. Microbial agents, as an important product that can effectively improve soil structure, enhance soil fertility, and enhance soil microbial activity, are increasingly widely used in agricultural production.

[0003] At present, there are many types of microbial agent preparation devices for improving soil, but in practical applications, these devices generally have some problems. In the preparation process of microbial agents, the growth and reproduction of microorganisms are extremely sensitive to environmental conditions, among which temperature is a key factor. The appropriate temperature range can promote the metabolism of microorganisms, increase their activity and reproduction rate, thereby ensuring the quality and effect of the agent. However, the existing microbial agent preparation devices have obvious deficiencies in temperature control and stirring speed regulation.

[0004] Most existing preparation devices are unable to automatically adjust the stirring speed in real time according to temperature changes. On the one hand, when the temperature inside the device is too high, due to the lack of an effective adjustment mechanism, the stirring speed remains unchanged, which will cause more friction heat to be generated during the stirring process, further increasing the temperature inside the device. Excessive temperature will denature the proteins in the microorganisms and reduce the enzyme activity, seriously affecting the growth and metabolism of the microorganisms, and may even cause the death of the microorganisms, thereby reducing the activity and quality of the microbial inoculant. At the same time, excessively high temperatures may also cause the decomposition and deterioration of certain nutrients in the culture solution, affecting the nutrient supply of the microorganisms, and further affecting the preparation effect of the inoculant. Summary of the invention

[0014] Furthermore, the driving member comprises:

[0015] The heat-conducting tube is connected to the mounting base and has a cavity therein;

[0016] The first piston plate is arranged in the cavity and can slide vertically along the axis direction of the heat-conducting cylinder to divide the cavity into a storage space and a telescopic space. The top of the first piston plate is connected to the bottom of the telescopic column, wherein:

[0017] The storage space is used for storing the thermal expansion medium, and the expansion space is used for providing an expansion area.

[0018] Furthermore, it also includes a stirring auxiliary component, which includes:

[0019] The jet pipe is connected to the inner bottom wall of the mixing drum and is arranged in a vortex shape and has a plurality of vent holes;

[0020] The inflator is arranged on the top of the mounting base and on one side of the mixing drum, and one side of the inflator is connected with the air injection pipe through a connecting pipe;

[0021] The second piston plate is vertically slidably connected in the inflatable cylinder and is used to transport the gas in the inflatable cylinder to the jet pipe to blow up the suspended particles settled at the bottom of the mounting base. The top of the second piston plate is provided with a second driving assembly for driving it to reciprocate;

[0022] At least two vent holes are provided at the top of the inflator;

[0023] There are at least two one-way valves, one end of which is connected to the second piston plate and the other end is connected to the top of the inflation cylinder.

[0024] Further, the second driving assembly includes,

[0025] A connecting shaft is rotatably connected to the top of the mixing drum and rotates synchronously with the first synchronous wheel. A first bevel gear is connected to the connecting shaft, and a second bevel gear is meshedly connected to one side of the first bevel gear.

The other end of the transmission rod is rotatably connected with the first connecting plate, and the other end of the first connecting plate is rotatably connected with the second connecting plate.

[0027] Furthermore, it also includes:

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. During the preparation process, the stirring speed can be automatically adjusted according to the temperature in the cylinder to maintain a constant temperature environment. When the temperature rises, the thermal expansion medium expands due to heat, pushing the piston plate and the telescopic column downward, driving the resistance block close to the center of the circle, reducing the speed of the first synchronous wheel and reducing heat generation; when the temperature is too low, the speed is increased on the contrary. This can avoid protein denaturation and enzyme inactivation in microorganisms due to temperature discomfort, effectively inhibit the growth or even death of microorganisms, ensure the normal metabolic activities of microorganisms, provide them with a suitable growth environment, and help improve the quality and preparation efficiency of microbial agents, and ensure the activity and efficacy of the agents.

[0035] 2. The rotation of the first synchronous wheel drives the connecting shaft and the bevel gear transmission, so that the second piston plate moves back and forth up and down in the inflatable cylinder. Pressing the second piston plate downward can discharge the gas in the inflatable cylinder through the jet pipe, effectively blowing up the suspended particles settled at the bottom of the mixing cylinder, and avoiding the accumulation of particles affecting the mixing effect. In addition, the jet pipe is distributed in a vortex shape on the bottom wall of the mixing cylinder. Compared with simple-shaped pipes, it can cover a larger area. The gas ejected from the vent can act on a wider area, allowing more bottom particles to be blown up, increasing the contact and mixing opportunities between the particles and the culture solution, significantly enhancing the overall stirring effect, and improving the quality and efficiency of microbial inoculant preparation.

[0036] 3. The magnetic plate rotates with the stirring element, and the Hall sensor senses the change in its magnetic field and converts it into an electrical signal. After analysis, the speed information of the stirring element is obtained, thereby accurately controlling the extension and retraction frequency of the electric telescopic rod. The electric telescopic rod drives the driving rack to move linearly, and then the mounting plate moves in a circular motion through the driven gear, so that the spoiler changes its position in the mixing drum. The spoiler can affect a wider range of culture fluids and carriers, enhance the spoiler effect, effectively improve the mixing uniformity, ensure that the various components are fully mixed during the preparation of microbial inoculants, which is conducive to the growth of microorganisms and improves the quality of the inoculants. At the same time, it realizes the function of automatically adjusting the spoiler according to the stirring speed, thereby improving the preparation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-9 The present invention provides a technical solution: a microbial agent preparation device for improving soil, comprising a mounting base 1, a mixing drum 2 connected to the mounting base 1, and a mixing member 3 rotatably arranged in the mixing drum 2, including:

[0049] A first synchronous wheel 401 is rotatably connected to the top of the mixing drum 2 and is coaxially arranged with the stirring member 3. A second synchronous wheel 402 is also rotatably connected to the top of the mounting base 1 to drive the first synchronous wheel 401 to rotate;

[0050] The telescopic column 403 is disposed in the second synchronous wheel 402 and is located at the center thereof, and can slide vertically along the axis direction of the second synchronous wheel 402. A first driving member for driving the telescopic column 403 to slide vertically is disposed at the bottom thereof;

[0051] The transmission block 404 is horizontally slidably disposed in the second synchronous wheel 402, one end of which is rotatably connected to a short-circuit plate, and the other end of the short-circuit plate is rotatably connected to the telescopic column 403, wherein:

[0052] The short-circuit board is set at an angle;

[0053] The abutment block 405 is disposed outside the second synchronous wheel 402, one side of which is connected to the transmission block 404, and can move toward or away from the center of the second synchronous wheel 402, so as to adjust the transmission ratio between the second synchronous wheel 402 and the first synchronous wheel 401;

[0054] A servo motor 407 is connected to the top of the mounting base 1 and is used to drive the second synchronous wheel 402 to rotate;

[0055] A first synchronous belt 406 is transmission-connected between the first synchronous wheel 401 and the abutment block 405 .

[0056] It should be noted that a temperature control component may also be provided on the outside of the mixing drum 2 to further finely adjust the temperature inside the mixing drum 2, such as winding a spiral temperature control pipeline around the mixing drum 2 or providing a temperature control device. A fixed frame is connected to the top of the mounting base 1 for installing the servo motor 407. The first synchronous belt 406 is made of elastic material and has a certain deformation effect, which can generate corresponding deformation amount as the position of the resistance block 405 changes.

[0057] In specific implementation, when preparing the microbial inoculant, firstly, raw materials such as carrier and culture solution are added into the stirring drum 2, and then the servo motor 407 is started to drive the first synchronous wheel 401 and the stirring member 3 to rotate, so as to stir the carrier and the culture solution. In the stirring process, as the stirring speed increases, the friction between the stirrer and the culture solution and the shear force inside the culture solution will become greater and greater, and more heat will be generated. At this time, for some microorganisms in the drum, their metabolic activities are very sensitive to temperature during the process of growth and reproduction. If the temperature is too high, it may cause protein denaturation and enzyme inactivation in the microorganism, thereby inhibiting the growth of the microorganism or even causing its death.

[0058] To this end, the telescopic column 403 can be moved vertically downward so that the transmission block 404 is affected by the short-circuit plate and drives the resistance block 405 to move toward the center of the second synchronous wheel 402. At this time, the rotation speed of the first synchronous wheel 401 gradually decreases, thereby reducing the heat generated by stirring and maintaining a constant temperature environment in the mixing drum 2. Correspondingly, when the temperature is too low, the telescopic column 403 is moved vertically upward to move the resistance block 405 away from the center of the second synchronous wheel 402 to increase the rotation speed.

[0059] See also Figure 2 and Figure 5 , driving parts include,

[0060] The heat-conducting tube 501 is connected to the mounting base 1 and has a cavity 502 therein;

[0061] The first piston plate 503 is disposed in the cavity 502 and can slide vertically along the axis of the heat-conducting cylinder 501 to divide the cavity 502 into a storage space 5021 and a telescopic space 5022. The top of the first piston plate 503 is connected to the bottom of the telescopic column 403.

[0062] The storage space 5021 is used to store the thermal expansion medium, and the telescopic space 5022 is used to provide a telescopic area.

[0063] It should be noted that the thermal expansion medium can be selected from materials with good thermal expansion effects such as mercury or nitrogen.

[0064] In specific implementation, when the temperature in the mixing drum 2 increases:

[0065] The heat will be transferred to the heat-conducting tube 501 through the mixing tube 2 and the mounting base 1. Since the heat-conducting tube 501 has good thermal conductivity, the heat expansion medium in the storage space 5021 absorbs the heat.

[0066] The heat expansion medium expands in volume after being heated, generating downward pressure on the first piston plate 503 .

[0067] Because the first piston plate 503 can slide vertically along the axis of the heat-conducting cylinder 501 and its top is connected to the bottom of the telescopic column 403, the first piston plate 503 can slide downward under the pressure generated by the expansion of the thermal expansion medium, thereby driving the telescopic column 403 to move downward.

[0068] The downward movement of the telescopic column 403 will drive the transmission block 404 to slide horizontally in the second synchronous wheel 402 through the inclined short-circuit plate, so that the resistance block 405 is close to the center of the second synchronous wheel 402, thereby changing the transmission ratio between the second synchronous wheel 402 and the first synchronous wheel 401, reducing the rotation speed of the first synchronous wheel 401, and finally slowing down the stirring speed of the stirring element 3, reducing the heat generated by stirring.

[0069] See also Figure 3 , also includes a stirring auxiliary component, which includes,

[0070] The air injection pipe 601 is connected to the inner bottom wall of the mixing drum 2 and is arranged in a vortex shape and has a plurality of air holes thereon;

[0071] The inflating cylinder 602 is arranged on the top of the mounting base 1 and on one side of the mixing cylinder 2, and one side of the inflating cylinder 602 is connected to the air injection pipe 601 through a connecting pipe;

[0072] The second piston plate 603 is vertically slidably connected in the inflatable cylinder 602, and is used to transport the gas in the inflatable cylinder 602 to the jet pipe 601 to blow up the suspended particles settled at the bottom of the mounting base 1. The top of the second piston plate 603 is provided with a second driving component for driving it to reciprocate;

[0073] At least two air holes 604 are provided on the top of the inflator 602;

[0074] There are at least two one-way valves 605 , one end of which is connected to the second piston plate 603 , and the other end is connected to the top of the inflation cylinder 602 .

[0075] It should be noted that a return spring 708 is connected to the second piston plate 603 to assist the second piston plate 603 in rebounding.

[0076] In specific implementation, the second piston plate 603 is pressed downward to discharge the gas in the inflatable cylinder 602 through the air jet 601, and blow the suspended particles settled at the bottom of the mixing drum 2, thereby preventing the suspended particles from accumulating at the bottom and affecting the stirring and mixing effect. At the same time, the air jet 601 is arranged to be vortex-shaped and is distributed on the inner bottom wall of the mixing drum 2 in a spiral manner. Compared with a straight or other simple-shaped pipe, it can cover a larger area. When the gas is ejected from the vent hole on the air jet 601, it can act on a wider area at the bottom of the mixing drum 2, so that more suspended particles settled at the bottom are blown up, increasing the contact and mixing opportunities between the particles and the culture solution, thereby enhancing the overall stirring effect.

[0077] refer to Figure 7 , the second driving assembly includes,

[0078] The connecting shaft 701 is rotatably connected to the top of the mixing drum 2 and rotates synchronously with the first synchronous wheel 401. The connecting shaft 701 is connected to a first bevel gear 702, and one side of the first bevel gear 702 is meshedly connected to a second bevel gear 703;

[0079] The turntable 704 is coaxially arranged with the second bevel gear 703. The second bevel gear 703 is connected with a protrusion, and the protrusion is rotatably connected with a transmission rod 705. The other end of the transmission rod 705 is rotatably connected with a first connecting plate 706. The other end of the first connecting plate 706 is rotatably connected with a second connecting plate 707. The other end of the second connecting plate 707 is connected to the second piston plate 603.

[0080] In specific implementation, when the first synchronous wheel 401 rotates, it can drive the connecting shaft 701 to rotate synchronously. With the rotation of the connecting shaft 701, the first bevel gear 702 also starts to rotate. Since one side of the first bevel gear 702 is meshedly connected with the second bevel gear 703, according to the transmission principle of the bevel gear, the rotation of the first bevel gear 702 will drive the second bevel gear 703 to rotate. When the second bevel gear 703 rotates, the rotating disk 704 will also rotate synchronously, and the protrusion will perform circular motion with the rotating disk 704. Since one end of the transmission rod 705 is rotatably connected to the protrusion, and the other end is rotatably connected to the first connecting plate 706, the circular motion of the protrusion is converted into the swing of the first connecting plate 706 through the transmission rod 705.

[0081] The other end of the first connecting plate 706 is rotatably connected to the second connecting plate 707, and the other end of the second connecting plate 707 is connected to the second piston plate 603. The swing of the first connecting plate 706 is further transmitted through the second connecting plate 707, so that the second piston plate 603 moves up and down reciprocatingly in the inflator 602.

[0082] refer to Figure 2 and Fig. 9 , also includes,

[0083] The magnetic plate 801 is coaxially arranged with the stirring member 3, and a Hall sensor 802 is arranged on one side of the magnetic plate 801;

[0084] The electric telescopic rod 803 is arranged in the stirring element 3 and is electrically connected to the Hall sensor 802. The telescopic end of the electric telescopic rod 803 is connected to a driving rack 804. Both sides of the driving rack 804 are meshed and connected to a driven gear 805. The driven gear 805 is connected to a mounting plate 806. The other end of the mounting plate 806 extends to the outside of the stirring element 3 and is connected to a spoiler 807.

[0085] It should be noted that the Hall sensor 802 is a magnetoelectric conversion sensor based on the Hall effect, which can convert magnetic field signals into electrical signals. This is a prior art, so no further explanation is given here.

[0086] In specific implementation, the magnetic plate 801 will rotate synchronously with the rotation of the stirring member 3, and the Hall sensor 802 on one side of the magnetic plate 801 can sense the change in the magnetic field generated when the magnetic plate 801 rotates. When the stirring member 3 rotates, the magnetic field of the magnetic plate 801 periodically passes through the Hall sensor 802, and the Hall sensor 802 converts this magnetic field change into an electrical signal output. By analyzing and processing the electrical signal, the rotation speed information of the stirring member 3 can be obtained, and then the telescopic frequency of the electric telescopic rod 803 can be controlled;

[0087] The telescopic end of the electric telescopic rod 803 is connected to the driving rack 804. When the electric telescopic rod 803 is extended or retracted, the driving rack 804 will perform linear motion accordingly. Since both sides of the driving rack 804 are meshed with the driven gear 805, the linear motion of the driving rack 804 will be converted into the rotation of the driven gear 805. The driven gear 805 is connected to the mounting plate 806. The rotation of the driven gear 805 will drive the mounting plate 806 to perform circular motion around the axis of the driven gear 805. The other end of the mounting plate 806 extends to the outside of the stirring member 3 and is connected to the spoiler 807. The circular motion of the mounting plate 806 will move the spoiler 807 to different positions in the stirring drum 2. The spoiler 807 can affect a wider range of culture fluid and carriers during the stirring process, thereby enhancing the turbulence effect and improving the uniformity of mixing.

[0088] refer to Fig. 9 The spoiler plate 807 is provided with a plurality of spoiler holes, and a plurality of serrated spoiler grooves are provided along its circumference.

[0089] In specific implementation, the presence of multiple spoiler holes can form multiple small streams of fluid in the mixing drum 2 when passing through the spoiler 807. These streams interweave and collide with each other, breaking the original flow state of the fluid and increasing the turbulence of the fluid. The serrated spoiler grooves are distributed along the circumference of the spoiler 807, and their irregular shapes will further disrupt the flow path of the fluid. When the fluid flows through these serrations, complex eddies and vortices will be generated, increasing the shear force of the fluid, thereby further improving the stirring effect.

[0090] See also Figure 1 A mounting frame 12 is connected to the top of the mounting base 1 , and the Hall sensor 802 is connected to the mounting frame 12 .

[0091] During specific implementation, the provided mounting frame 12 facilitates the installation of the Hall sensor 802 .

[0092] refer to Figure 1 and Figure 7 A third synchronous wheel 9 is connected to the top of the stirring member 3 , a fourth synchronous wheel 10 is connected to the connecting shaft 701 , and a second synchronous belt 11 is connected between the fourth synchronous wheel 10 and the third synchronous wheel 9 .

[0093] In specific implementation, the third synchronous wheel 9 is provided to facilitate the transmission of the driving force of the stirring member 3 to the fourth synchronous wheel 10 through the second synchronous belt 11 to drive the connecting shaft 701 to rotate.

[0094] Working principle: When preparing microbial inoculants, firstly, raw materials such as carriers and culture solutions are added into the mixing drum 2, and then the servo motor 407 is started to drive the first synchronous wheel 401 and the stirring element 3 to rotate, so as to stir the carrier and the culture solution. During the stirring process, as the stirring speed increases, the friction between the stirrer and the culture solution and the shear force inside the culture solution will become greater and greater, and more heat will be generated. At this time, for some microorganisms in the drum, their metabolic activities are very sensitive to temperature during the process of growth and reproduction. If the temperature is too high, it may cause protein denaturation and enzyme inactivation in the microorganism, thereby inhibiting the growth of the microorganism or even causing its death.

[0095] When the temperature in the mixing drum 2 increases:

[0096] The heat will be transferred to the heat-conducting tube 501 through the mixing tube 2 and the mounting base 1. Since the heat-conducting tube 501 has good thermal conductivity, the heat expansion medium in the storage space 5021 absorbs the heat.

[0097] The heat expansion medium expands in volume after being heated, generating downward pressure on the first piston plate 503 .

[0098] Because the first piston plate 503 can slide vertically along the axis of the heat-conducting cylinder 501 and its top is connected to the bottom of the telescopic column 403, the first piston plate 503 can slide downward under the pressure generated by the expansion of the thermal expansion medium, thereby driving the telescopic column 403 to move downward.

[0099] To this end, the telescopic column 403 can be moved vertically downward so that the transmission block 404 is affected by the short-circuit plate and drives the resistance block 405 to move toward the center of the second synchronous wheel 402. At this time, the rotation speed of the first synchronous wheel 401 is gradually reduced, thereby reducing the heat generated by stirring and maintaining a constant temperature environment in the mixing drum 2. Correspondingly, when the temperature is too low, the telescopic column 403 is moved vertically upward to move the resistance block 405 away from the center of the second synchronous wheel 402 to increase the rotation speed.

[0100] When the first synchronous wheel 401 rotates, it can drive the connecting shaft 701 to rotate synchronously. As the connecting shaft 701 rotates, the first bevel gear 702 also starts to rotate. Since one side of the first bevel gear 702 is meshedly connected with the second bevel gear 703, according to the transmission principle of the bevel gear, the rotation of the first bevel gear 702 will drive the second bevel gear 703 to rotate. When the second bevel gear 703 rotates, the rotating disk 704 will also rotate synchronously, and the protrusion will perform circular motion with the rotating disk 704. Since one end of the transmission rod 705 is rotatably connected to the protrusion and the other end is rotatably connected to the first connecting plate 706, the circular motion of the protrusion is converted into the swing of the first connecting plate 706 through the transmission rod 705.

[0101] The other end of the first connecting plate 706 is rotatably connected to the second connecting plate 707, and the other end of the second connecting plate 707 is connected to the second piston plate 603. The swing of the first connecting plate 706 is further transmitted through the second connecting plate 707, so that the second piston plate 603 moves up and down reciprocatingly in the inflatable cylinder 602;

[0102] The second piston plate 603 is pressed downward to discharge the gas in the inflation cylinder 602 through the air jet 601, and blow the suspended particles settled at the bottom of the mixing drum 2, thereby preventing the suspended particles from accumulating at the bottom and affecting the mixing effect. At the same time, the air jet 601 is set to be vortex-shaped and is distributed on the inner bottom wall of the mixing drum 2 in a spiral manner. Compared with a straight or other simple-shaped pipe, it can cover a larger area. When the gas is ejected from the vent hole on the air jet 601, it can act on a wider area at the bottom of the mixing drum 2, so that more suspended particles settled at the bottom are blown up, increasing the contact and mixing opportunities between the particles and the culture solution, thereby enhancing the overall mixing effect;

[0103] The magnetic plate 801 will rotate synchronously with the rotation of the stirring member 3, and the Hall sensor 802 on one side of the magnetic plate 801 can sense the change in the magnetic field generated when the magnetic plate 801 rotates. When the stirring member 3 rotates, the magnetic field of the magnetic plate 801 periodically passes through the Hall sensor 802, and the Hall sensor 802 converts this magnetic field change into an electrical signal output. By analyzing and processing the electrical signal, the rotation speed information of the stirring member 3 can be obtained, and then the telescopic frequency of the electric telescopic rod 803 can be controlled;

[0104] The telescopic end of the electric telescopic rod 803 is connected to the driving rack 804. When the electric telescopic rod 803 is extended or retracted, the driving rack 804 will perform linear motion accordingly. Since both sides of the driving rack 804 are meshed with the driven gear 805, the linear motion of the driving rack 804 will be converted into the rotation of the driven gear 805. The driven gear 805 is connected to the mounting plate 806. The rotation of the driven gear 805 will drive the mounting plate 806 to perform circular motion around the axis of the driven gear 805. The other end of the mounting plate 806 extends to the outside of the stirring member 3 and is connected to the spoiler 807. The circular motion of the mounting plate 806 will move the spoiler 807 to different positions in the stirring drum 2. The spoiler 807 can affect a wider range of culture fluid and carriers during the stirring process, thereby enhancing the turbulence effect and improving the uniformity of mixing.
