Technical Field
[0001] The invention relates to the technical field of returning straw to fields, and in particular to a microbial fermentation pretreatment device for returning straw to fields. Background Art
[0002] Returning straw to the field is a measure to return straw to the field. It is a measure to improve soil fertility and increase production that is widely valued in the world. It not only eliminates the air pollution caused by straw burning, but also has the effect of increasing fertilizer and production. In returning straw to the field, it is necessary to ferment the straw with microorganisms to remove impurities in the straw, and add appropriate elements to the straw, which will form a beating effect on the straw and improve the effect of returning straw to the field. Before the straw is fermented with microorganisms, it is necessary to pre-treat the straw; Pretreatment is an important step in the microbial fermentation process. Its main purpose is to prepare for the subsequent separation and purification operations. When pretreating the straw, the straw needs to be soaked in the culture solution to soften the straw while removing impurities such as protein, heavy metal ions, pigments, pyrogens, toxins, etc. inside the straw. The appropriate temperature and pH can be adjusted to reduce the damage and loss of the target product. At present, the main method is to place the straw directly in the culture solution and wait quietly. The operation is simple. However, in the actual processing process, since the straw is light, the straw will float on the water surface, slowing down the mixing efficiency. Sometimes it is necessary to press the straw manually, which is time-consuming and labor-intensive. Sometimes the straw surface is hard, which will seriously hinder the mixing efficiency and greatly increase the mixing time. Therefore, a microbial fermentation pretreatment equipment for returning straw to the field is provided. Summary of the invention

Since the moving plate is heavy, it will form a squeezing effect on the straw, which not only prevents the straw from floating on the water surface, but also keeps the straw in motion because the moving plate is constantly moving up and down and is in a shaking state, thereby accelerating the mixing rate. 2. During pretreatment, the straw that is not completely mixed with the culture solution is lighter and will accumulate on the lower side of the moving plate. During the up and down movement of the moving plate, the beating rod will be driven to move continuously. Since the beating rod and the straw are against each other, a beating effect will be formed on the straw, damaging the surface of the straw, thereby further accelerating the mixing efficiency of the straw and the culture solution. 3. Finally, in the process of the beating rod moving up and down, under the action of the two rotating plates, the two rotating plates drive the square rod to rotate, and the square rod drives the beating rod to rotate, shortening the straight-line distance between the two beating rods. The two groups of beating rods and the straw are offset against each other, forming a straw squeezing effect, destroying the straw, and further improving the mixing effect with the culture solution.

DETAILED DESCRIPTION
[0014] See also Figure 1-Figure 8 A microbial fermentation pretreatment device for returning straw to the field comprises a cylinder 1, a drain pipe is fixedly connected to the lower side of the cylinder 1, a control valve is installed on the outer side of the drain pipe, a bracket 2 is fixedly connected to the outer side of the cylinder 1, and a first hydraulic rod 3 is fixedly connected to the upper side of the bracket 2. Figure 2 The lower side of the first hydraulic rod 3 is fixedly connected with a cylinder cover 4, the lower side of the cylinder cover 4 is fixedly connected with a motor 5, the output end of the motor 5 is fixedly connected with a rotating shaft 6, the outer side of the rotating shaft 6 is provided with a threaded groove 11, the outer side of the rotating shaft 6 is evenly fixedly connected with multiple groups of stirring rods 10, the lower side of the rotating shaft 6 is rotatably connected with a bottom plate 8, the outer side of the rotating shaft 6 is also sleeved with a moving plate 7, the upper side of the moving plate 7 is evenly provided with multiple groups of through holes 901, the upper side of the moving plate 7 is also provided with multiple groups of through grooves 12, and the multiple groups of through grooves 12 and the stirring rods 10 are arranged relatively; First, when it is necessary to pre-treat the straw by microbial fermentation, pour an appropriate amount of culture solution into the barrel 1, start the first hydraulic rod 3, and the first hydraulic rod 3 drives the barrel cover 4 to move downward. During this process, put the straw into the barrel 1 until the barrel cover 4 covers the upper side of the barrel 1. At this time, the straw is located between the movable plate 7 and the bottom plate 8, heat the barrel 1, and start the motor 5. The motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the stirring rod 10 to rotate, and the pre-treatment operation begins until the inside of the straw is completely mixed with the culture solution, then the motor 5 is turned off, and the first hydraulic rod 3 is started again. The first hydraulic rod 3 drives the barrel cover 4 and the motor 5 to move upward as a whole, and the motor 5 drives the rotating shaft 6 and the bottom plate 8 to move upward. The straw is on the upper side of the bottom plate 8 and moves upward with the bottom plate 8 until the straw is removed from the barrel 1. The straw is removed from the bottom plate 8, and then the control valve is opened to discharge the liquid retained in the barrel 1, thereby completing the pre-treatment operation of the straw. The above are all prior arts and no unnecessary elaboration is made. like Figure 3 , Figure 4 , Figure 5 A shaking assembly 9 for controlling the shaking of the moving plate 7 is installed on the lower side of the moving plate 7. The shaking assembly 9 includes a sensor 902 fixedly installed on the lower side of the moving plate 7. A reciprocating rod 905 is fixedly connected between the sensor 902 and the moving plate 7. A foam plate 906 is slidably sleeved on the outer side of the reciprocating rod 905. The foam plate 906 is located on the lower side of the sensor 902. A plurality of fixed boxes 903 are evenly fixedly connected to the lower side of the moving plate 7. The fixed boxes 903 and the through holes 901 are staggered. The movable plate 7 has multiple groups of cavities 907, and the multiple groups of cavities 907 and the fixed box 903 are arranged in a one-to-one matching manner. The inner side walls of the multiple groups of cavities 907 are fixedly connected to the second hydraulic rod 908, and the output end of the second hydraulic rod 908 is fixedly connected to the regulating plate 909. A first spring 910 is fixedly connected between the regulating plate 909 and the cavity 907. A plug rod 914 is fixedly connected to the side wall of the regulating plate 909 in one of the cavities 907, and the plug rod 914 and the threaded groove 11 are arranged in a relative manner; First, the foam board 906 can float on the water surface. Second, there is only one side wall of the regulating plate 909 in the cavity 907 fixedly connected with the plug rod 914. In addition, the sensor 902 is an ordinary pressure sensor 902 in real life, which is mainly composed of a pressure sensitive element and a signal processing unit, and the sensor 902 is electrically connected to the controller that controls the switch of the first hydraulic rod 3 through a wire. When the straw is put into the cylinder 1, the straw will float on the water surface. When the moving plate 7 moves downward, the moving plate 7 and the straw will be offset, which will drive the straw to move downward, so that the straw is completely immersed in the water surface, which can In order to better mix with the culture solution, and when the moving plate 7 goes deep into the water surface, the foam plate 906 has a smaller density and will move upward relative to the sensor 902 and counter the sensor 902. The deeper the moving plate 7 goes into the water surface, the greater the buoyancy of the foam plate 906, which will cause the electrical signal emitted by the sensor 902 to be greater, until the electrical signal emitted by the sensor 902 can activate the controller that controls the switch circuit of the second hydraulic rod 908. At this time, the second hydraulic rod 908 is activated, and the second hydraulic rod 908 drives the regulating plate 909 to move, and the regulating plate 909 compresses the first spring 910 to Figure 5Based on the direction, the regulating plate 909 drives the plug rod 914 to move to the left, and the plug rod 914 enters the threaded groove 11. Since the motor 5 drives the rotating shaft 6 to rotate, and the cylinder 1 and the movable plate 7 are both regular polygons, the cylinder 1 will limit the movement of the movable plate 7, so that the movable plate 7 can only move up and down relative to the cylinder 1, but cannot rotate. Therefore, when the plug rod 914 enters the slot, it will cause the movable plate 7 to move upward. At this time, the buoyancy of the foam plate 906 becomes smaller, and the electrical signal generated by the sensor 902 becomes weaker until the controller controlling the switch of the second hydraulic rod 908 cannot be started. At this time, under the action of the first spring 910, the regulating plate 909 drives the plug rod 914 to move to the right, and the connection between the plug rod 914 and the threaded groove 11 is disconnected. At this time, under the action of the movable plate 7's own gravity, the movable plate 7 moves downward until the second hydraulic rod 908 is opened again, thereby causing the movable plate 7 to move up and down all the time during the pretreatment process and be in a shaking state, which can not only prevent the straw from floating on the water surface, but also form a certain extrusion on the straw, thereby accelerating the mixing rate.
[0015] like Figure 6 , Figure 7 , Figure 8 , multiple groups of fixed boxes 903 are all equipped with extrusion components for straw, the extrusion components include two groups of knocking grooves 927 opened on the lower side of the fixed box 903, the knocking rods 904 are arranged through the knocking grooves 927, the two groups of knocking grooves 927 are rotatably connected with square rods 924, the side walls of multiple groups of knocking rods 904 are all opened with square grooves, the square rods 924 are inserted into the square grooves and are slidably connected with the square grooves, the side walls of the square rods 924 are fixedly connected with rotating plates 926, and the two groups of rotating plates 926 are staggered; First, when the second hydraulic lever 908 is activated, Figure 6 Based on the direction, the sawtooth plate 911 will move to the left. Under the limiting effect of the second spring 920, the sawtooth plate 911 always contacts the raised plate 912, and the contact surface of the sawtooth plate 911 and the raised plate 912 is smooth. Due to the special shapes of the sawtooth plate 911 and the raised plate 912, such as Figure 6As shown, and under the limiting action of the moving rod 915, the raised plate 912 can only move up and down relative to the cavity 907. When the raised portion on the upper side of the raised plate 912 and the tip portion of the serrated plate 911 are against each other, the raised plate 912 is in the lowest position. When the raised portion on the upper side of the raised plate 912 and the gap of the serrated plate 911 are against each other, the raised plate 912 is in the highest position, which ultimately results in the raised plate 912 moving up and down relative to the cavity 907 during the movement of the serrated plate 911. The raised plate 912 drives the control plate 916 to move up and down through the moving rod 915. The control plate 916 drives the control rod 922 to move up and down. The control rod 922 drives the knocking rod 904 to move up and down. Since the straw that is not completely mixed with the culture solution is lighter, it will accumulate on the lower side of the moving plate 7. The knocking rod 904 and the straw are against each other, which will form a knocking effect on the straw, destroying the surface of the straw, thereby further accelerating the mixing efficiency of the straw and the culture solution.
[0016] The output end side wall of the second hydraulic rod 908 is also fixedly connected to a connecting rod 919, and the side of the connecting rod 919 away from the second hydraulic rod 908 is fixedly connected to a second trapezoidal plate 918. A right-angle rod 923 is also slidably sleeved up and down on the upper side of the fixed box 903. One end of the right-angle rod 923 located in the cavity 907 is fixedly connected to the first trapezoidal plate 917. The first trapezoidal plate 917 is located on the upper side of the second trapezoidal plate 918 and abuts against the second trapezoidal plate 918. The right-angle rod 923 is located on one side of the fixed box 903 at the lower side of the intersection of the two rotating plates 926 and abuts against the two rotating plates 926. First, when the second hydraulic rod 908 is not activated, the knocking rod 904 moves vertically downward under the action of its own gravity, and all the knocking rods 904 are in a parallel state. Since the straw that is not completely mixed with the culture solution is lighter, it will accumulate on the lower side of the movable plate 7. Some straw is located between two adjacent groups of knocking rods 904. When the second hydraulic rod 908 is activated, it will drive the connecting rod 919 to move left, and the connecting rod 919 will drive the second trapezoidal plate 918 to move left. The second trapezoidal plate 918 and the first trapezoidal plate 917 will offset each other and drive the first trapezoidal plate 917 to move upward. The second trapezoidal plate 918 drives the right-angle rod 923 to move upward. The right-angle rod 923 and the two rotating plates 926 will abut against each other, which will drive the two rotating plates 926 to move upward. Since the two rotating plates 926 cannot move upward under the action of the square rod 924, under the action of the right-angle rod 923, the two rotating plates 926 can only rotate around the square rod 924. The two rotating plates 926 drive the square rod 924 to rotate, and the square rod 924 drives the knocking rod 904 to rotate, shortening the straight-line distance between the two knocking rods 904. The two groups of knocking rods 904 and the straw are abutted against each other, forming a straw squeezing effect, destroying the straw, and further improving the mixing effect with the culture solution.
[0017] The outer sides of the first trapezoidal plate 917 and the second trapezoidal plate 918 are both smooth, so as to reduce the friction between the first trapezoidal plate 917 and the second trapezoidal plate 918 .
[0018] The multiple groups of beating rods 904 are arranged in an arc shape on one side away from the fixed box 903, which can better achieve the effect of destroying the straw and further improve the mixing rate.
[0019] The outer side walls of multiple groups of knocking rods 904 are fixedly sleeved with rubber sleeves to increase the friction between adjacent knocking rods 904 and the straw, thereby better forming an extrusion and destruction effect on the straw.
[0020] In the present invention, when it is necessary to pre-treat the straw by microbial fermentation, pour an appropriate amount of culture solution into the barrel 1, start the first hydraulic rod 3, and the first hydraulic rod 3 drives the barrel cover 4 to move downward. During this process, the straw is put into the barrel 1 until the barrel cover 4 covers the upper side of the barrel 1. At this time, the straw is located between the movable plate 7 and the bottom plate 8, the barrel 1 is heated, and the motor 5 is started. The motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the stirring rod 10 to rotate, and the pre-treatment operation begins until the inside of the straw is completely mixed with the culture solution, then the motor 5 is turned off, and the first hydraulic rod 3 is started again. The first hydraulic rod 3 drives the barrel cover 4 and the motor 5 to move upward as a whole, and the motor 5 drives the rotating shaft 6 and the bottom plate 8 to move upward. The straw is on the upper side of the bottom plate 8 and moves upward with the bottom plate 8 until the straw is removed from the barrel 1. The straw is removed from the bottom plate 8, and then the control valve is opened to release the liquid retained in the barrel 1. The body is discharged, thereby completing the pretreatment operation of the straw. The above are all existing technologies and no unnecessary details are given. When the straw is put into the barrel 1, the straw will float on the water surface. When the movable plate 7 moves downward, the movable plate 7 and the straw will be against each other, which will drive the straw to move downward, so that the straw can completely penetrate into the water surface and can be better mixed with the culture solution. When the movable plate 7 penetrates into the water surface, the foam plate 906 has a smaller density and will move upward relative to the sensor 902 and against the sensor 902. The deeper the movable plate 7 penetrates into the water surface, the greater the buoyancy of the foam plate 906 is, and the greater the electrical signal emitted by the sensor 902 is, until the electrical signal emitted by the sensor 902 can start the controller that controls the switch circuit of the second hydraulic rod 908. At this time, the second hydraulic rod 908 is started, and the second hydraulic rod 908 drives the regulating plate 909 to move, and the regulating plate 909 compresses the first spring 910 to Figure 5Based on the direction, the regulating plate 909 drives the plug rod 914 to move to the left, and the plug rod 914 enters the threaded groove 11. Since the motor 5 drives the rotating shaft 6 to rotate, and the cylinder 1 and the movable plate 7 are both regular polygons, the cylinder 1 will limit the movement of the movable plate 7, so that the movable plate 7 can only move up and down relative to the cylinder 1, but cannot rotate. Therefore, when the plug rod 914 enters the slot, it will cause the movable plate 7 to move upward. At this time, the buoyancy of the foam plate 906 becomes smaller, and the electrical signal generated by the sensor 902 becomes weaker until the controller controlling the switch of the second hydraulic rod 908 cannot be started. At this time, under the action of the first spring 910, the regulating plate 909 drives the plug rod 914 to move to the right, and the connection between the plug rod 914 and the threaded groove 11 is disconnected. At this time, under the action of the movable plate 7's own gravity, the movable plate 7 moves downward until the second hydraulic rod 908 is opened again, thereby causing the movable plate 7 to move up and down all the time during the pretreatment process, and be in a shaking state, which can not only prevent the straw from floating on the water surface, but also form a certain amount of extrusion on the straw, thereby accelerating the mixing rate; When the second hydraulic lever 908 is activated, Figure 6 Based on the direction, the sawtooth plate 911 will be driven to move leftward. Under the limiting effect of the second spring 920, the sawtooth plate 911 is always against the raised plate 912, so the raised plate 912 will be driven to move up and down. The raised plate 912 drives the control plate 916 to move up and down through the moving rod 915. The control plate 916 drives the control rod 922 to move up and down. The control rod 922 drives the knocking rod 904 to move up and down. Since the straw that is not completely mixed with the culture solution is lighter, it will accumulate on the lower side of the moving plate 7. The knocking rod 904 and the straw are against each other, which will form a knocking effect on the straw, destroying the surface of the straw, thereby further accelerating the mixing efficiency of the straw and the culture solution. When the second hydraulic rod 908 is not activated, the knocking rod 904 moves vertically downward under the action of its own gravity, and all the knocking rods 904 are in a parallel state. Since the straw that is not completely mixed with the culture solution is lighter, it will accumulate on the lower side of the movable plate 7. Some straw is located between two adjacent groups of knocking rods 904. When the second hydraulic rod 908 is activated, it will drive the connecting rod 919 to move leftward, and the connecting rod 919 will drive the second trapezoidal plate 918 to move leftward. The second trapezoidal plate 918 and the first trapezoidal plate 917 will offset each other and drive the first trapezoidal plate 917 to move upward. The second trapezoidal plate 918 will drive the right-angle rod 923 to move upward. The right-angle rod 923 and the two rotating plates 926 will abut against each other, which will drive the two rotating plates 926 to move upward. Since the two rotating plates 926 cannot move upward under the action of the square rod 924, under the action of the right-angle rod 923, the two rotating plates 926 can only rotate around the square rod 924. The two rotating plates 926 drive the square rod 924 to rotate, and the square rod 924 drives the knocking rod 904 to rotate, shortening the straight-line distance between the two knocking rods 904. The two groups of knocking rods 904 and the straw are abutted against each other, forming a straw squeezing effect, destroying the straw, and further improving the mixing effect with the culture solution.
