DETAILED DESCRIPTION

[0029] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0030] According to the attached Figure 1 As shown, a stirring and mixing device for producing microbial fertilizers includes a device body 100, and the device body 100 includes a tank body 101, and a tank cover 102 is provided on the tank body 101. When the tank body 101 and the tank cover 102 are closed, a mixing chamber is formed between the tank body 101 and the tank cover 102 for accommodating the microbial fertilizer to be processed. In the prior art, a lifting device is installed on the tank cover 102, so that the tank cover 102 can move up and down freely, so that the tank body 101 and the tank cover 102 can be opened or closed.

[0031] Among them, at least two feed ports 103 are also installed on the tank cover 102, one of which is used to connect to an external fertilizer supply pipeline to transport the fertilizer raw materials, and the other is used to connect to an external microbial supply pipeline to transport the microbial additive raw materials, so as to facilitate continuous feeding into the mixing chamber and processing of microbial fertilizers. In addition, a discharge port 104 is also installed on the tank body 101, and a material control valve is installed on the discharge port 104 to control the material discharge speed. On this basis, a motor 105 is installed on the tank cover 102, and a controller 106 is installed on the tank body 101.

[0032] Specifically, according to the attached Figure 2 and attached Figure 3 As shown, a stirring shaft 107 is provided in the tank 101, and a plurality of stirring blades 108 are installed on the stirring shaft 107, which are used to stir and mix the microbial fertilizer to be processed in the mixing chamber. A de-agglomeration mechanism 300 is also provided on the stirring shaft 107, and the de-agglomeration mechanism 300 is used to break up and crush the raw materials in the mixing chamber, further increasing the mixing effect of the microbial fertilizer, thereby avoiding the occurrence of agglomeration.

[0033] In addition, the output shaft of the motor 105 is connected to the stirring shaft 107 via a switching mechanism 400. In the present embodiment, the switching mechanism 400 is used to control the rotation speed of the stirring shaft 107 to prevent the stirring shaft 107 from being subjected to uneven force and vibration due to uneven distribution of external raw materials and increased resistance when the material in the mixing chamber forms agglomerations or lumps over a large area, thereby affecting the stability and load bearing capacity of the equipment, as well as its service life.

[0034] It should be noted that in order to avoid vibration damage to the stirring shaft 107 caused by uneven force due to agglomeration, please refer to the attached Figure 1 In this embodiment, a vibration sensor 200 is installed on the tank body 101 to detect the vibration emitted from the inside of the tank body 101. When in use, the vibration sensor 200 is calibrated to ensure the accuracy of the measurement. In specific implementation, a threshold value of the vibration value is set according to the normal operating range and standard of the equipment. When the vibration value exceeds the set threshold value, the vibration sensor 200 uploads a signal to the controller 106 for subsequent operations.

[0035] According to the attached Figure 3 To Attachment Figure 5As shown, the deagglomeration mechanism 300 includes a connecting shaft 301 movably connected to the inside of the stirring shaft 107, a movable groove and a limiting square groove are provided in the stirring shaft 107, the movable groove and the limiting square groove are connected to each other, the movable groove allows the connecting shaft 301 to slide up and down, a rack column 302 is provided in the limiting square groove, and the rack column 302 is fixedly connected to the connecting shaft 301. That is, when the connecting shaft 301 moves up and down, the connecting shaft 301 can drive the rack column 302 to move synchronously.

[0036] Specifically, first gears 303 are staggered around the rack column 302, and the first gears 303 are meshed with the rack column 302. When the connecting shaft 301 drives the rack column 302 to move up and down, the rack column 302 meshes with the first gears 303 to control the first gears 303 to rotate.

[0037] Among them, a first rotating shaft 304 is installed in the first gear 303, and both ends of the first rotating shaft 304 pass through the stirring shaft 107 and are installed with a first swing arm 305. In this embodiment, the first rotating shaft 304 is connected to the stirring shaft 107 by a bearing. A first cutter 306 is installed on the first swing arm 305, and the first cutter 306 is used to cut the agglomerated or lumped materials in the mixing chamber and break up the agglomerated materials, thereby facilitating the production and processing of the microbial fertilizer and further improving the mixing effect.

[0038] It should be understood that when the rack column 302 is meshed and connected with the first gear 303 to control the first gear 303 to rotate, the first swing arm 305 rotates synchronously, thereby driving the first cutter 306 to rotate, so that the first cutter 306 is extended outward, so that when the stirring shaft 107 rotates, the first cutter 306 can crush the material in the mixing chamber and break up the agglomerated fertilizer, thereby further improving the mixing effect.

[0039] Furthermore, according to the attached Figure 2 and attached Figure 3 As shown, a first connecting frame 307 is further provided in the tank body 101, and a convex column is provided in the middle of the first connecting frame 307, and the convex column is connected to the first connecting frame 307 by a bearing, and the convex column is made of a magnetic material, preferably a magnet. The material of the rack column 302 is metal. When the convex column contacts the rack column 302, the convex column and the rack column 302 are magnetically connected.

[0040] Among them, according to the attached Figure 2 , Attachment Figure 6 and attached Figure 7As shown, a sealing plate 1011 is installed around the inside of the tank body 101, and a first rack plate 308 is provided inside the sealing plate 1011. The first rack plate 308 is located around the first connecting frame 307, and the first connecting frame 307 and the first rack plate 308 are fixedly connected. In this embodiment, when the boss is magnetically connected to the rack column 302, when the rack column 302 moves up and down, the driving boss moves synchronously, thereby controlling the first connecting frame 307 to drive the first rack plate 308 to move up and down. A plurality of second gears 309 are meshedly connected to the first rack plate 308. When the first rack plate 308 moves up and down, the first rack plate 308 controls the second gears 309 to rotate.

[0041] It should be noted that a second rotating shaft 310 is installed inside the second gear 309, and both ends of the second rotating shaft 310 are installed with second swing arms 311 through the sealing plate 1011, and a second cutter 312 is installed on the second swing arm 311. When the first rack plate 308 drives the second gear 309 to rotate, the second gear 309 drives the second swing arm 311 to rotate synchronously through the action of the second rotating shaft 310, so that the second cutter 312 is deployed to the outside to crush the materials in the mixing chamber to eliminate the agglomeration phenomenon. Among them, the second cutter 312 is used to cooperate with the first cutter 306 to crush the agglomerated or lumped materials in the mixing chamber, thereby further improving the mixing efficiency.

[0042] According to the attached Figure 4 As shown, the first recess 10111 is provided at the position corresponding to the first swing arm 305 on the stirring shaft 107, so as to provide a space for the first swing arm 305 to facilitate the storage and folding of the first cutter 306 when the first cutter 306 is folded. Figure 7 As shown, a second recess 1071 is provided at a position on the sealing plate 1011 corresponding to the second swing arm 311, so as to provide a space for the second swing arm 311 when the second cutter 312 is folded, so as to facilitate the storage and folding of the second cutter 312.

[0043] According to the attached Figure 8 and attached Fig. 9 As shown, the switching mechanism 400 includes a loading frame 401 mounted on the tank cover 102, and the loading frame 401 is detachably connected to the motor 105 through fasteners such as bolts and latches. Specifically, a driving shaft 402 and a driven shaft 403 are rotatably connected to the loading frame 401 through a bearing, and the driving shaft 402 and the driven shaft 403 are connected through a speed control mechanism, and the speed control mechanism is used to control the rotation speed of the driven shaft 403.

[0044] Furthermore, one end of the driven shaft 403 passes through the tank cover 102 and is fixedly connected to the stirring shaft 107. A through hole 4031 is also provided inside the driven shaft 403, and the through hole 4031 is slidably connected to the connecting shaft 301. The through hole 4031 is also connected to the inside of the movable groove, so that the connecting shaft 301 can move up and down. In addition, a second shaft sleeve 409 is installed on the loading frame 401, and a second spline shaft 410 is slidably connected inside the second shaft sleeve 409. The spline groove matching the spline shaft is provided inside the second shaft sleeve 409, so that the spline shaft can be circumferentially limited, so that the spline shaft can only move up and down, and cannot rotate.

[0045] It should be noted that the second spline shaft 410 is rotatably connected to the connecting shaft 301 via a bearing, second connecting frames 411 are installed on both sides of the second spline shaft 410, and sliders 412 are installed on the second connecting frames 411, and the sliders 412 are connected to the speed control mechanism.

[0046] According to the attached Fig. 9 and attached Fig.10 As shown, the speed control mechanism includes two sets of first speed change wheels 404 arranged on the driving shaft 402 and two sets of second speed change wheels 405 arranged on the driven shaft 403, and the adjacent sides of the two sets of first speed change wheels 404 and the two sets of second speed change wheels 405 are all inclined.

[0047] Specifically, a driving wheel mechanism is formed between the two first speed-changing wheels 404 , a driven wheel mechanism is formed between the two second speed-changing wheels 405 , and the driving wheel mechanism and the driven wheel mechanism are connected through a belt 406 .

[0048] Furthermore, according to the attached Fig.10 As shown, the driving shaft 402 and the driven shaft 403 are both mounted with a first spline shaft 407, and each first spline shaft 407 is slidably connected with two sets of first bushings 408, and the first bushings 408 are respectively fixedly connected to the first speed change wheel 404 and the second speed change wheel 405, so that the first speed change wheel 404 and the second speed change wheel 405 can move closer to or away from each other on the driving shaft 402 and the driven shaft 403, respectively.

[0049] It should be understood that when the two groups of first speed change wheels 404 are close to each other, the diameters between the first speed change wheels 404 can be synchronously expanded by setting the inclined surfaces, and when the two groups of first speed change wheels 404 are away from each other, the diameters between the first speed change wheels 404 can be synchronously reduced by setting the inclined surfaces, thereby changing the transmission diameter of the driving wheel mechanism.

[0050] Similarly, when the two sets of second speed-changing wheels 405 are close to each other, the inclined surfaces can be set so that the diameters between the second speed-changing wheels 405 can be synchronously expanded, and when the two sets of second speed-changing wheels 405 are away from each other, the inclined surfaces can be set so that the diameters between the second speed-changing wheels 405 can be synchronously reduced, thereby changing the transmission diameter of the driven wheel mechanism. Thus, the transmission ratio of the driving wheel mechanism and the driven wheel mechanism can be adjusted by the diameter ratio between the driving wheel mechanism and the driven wheel mechanism.

[0051] According to the attached Fig.11 As shown, shafts 413 are provided on both upper and lower sides of the belt 406, and the shafts 413 are connected to the loading frame 401 with bearings, and connecting rods 414 are installed on both sides of the shafts 413, and adjusting rods 415 are installed on both ends of the connecting rods 414. Among them, a first adjusting groove 4041 is provided on the first speed-changing wheel 404, and a second adjusting groove 4051 is provided on the second speed-changing wheel 405. The first adjusting groove 4041 and the second adjusting groove 4051 are both annularly arranged. The adjusting rods 415 are slidably connected to the first adjusting groove 4041 and the second adjusting groove 4051, respectively.

[0052] It should be noted that, through the setting of the connecting rod 414, the first speed-changing wheel 404 and the second speed-changing wheel 405 can be adjusted in a coordinated manner. That is, when the connecting rod 414 controls the two first speed-changing wheels 404 to move closer to each other, the two second speed-changing wheels 405 move away from each other. When the connecting rod 414 controls the two second speed-changing wheels 405 to move away from each other, the two second speed-changing wheels 405 move closer to each other.

[0053] Specifically, a hanging plate is installed at one end of the connecting rod 414, and a spring 416 is installed between every two adjacent hanging plates. The setting of the spring 416 can assist the connecting rod 414 in resetting and provide traction force for the connecting rod 414.

[0054] Furthermore, according to the attached Figure 8 To Attachment Fig.11 As shown, a transmission gear 417 is also installed on the shaft 413, and the transmission gears 417 are meshingly connected to each other. A second rack plate 418 is meshingly connected to one group of the transmission gears 417. An electric push rod 419 is also installed on the loading frame 401, and the telescopic end of the electric push rod 419 is fixedly connected to the second rack plate 418.

[0055] It should be noted that when the electric push rod 419 performs telescopic movement, the electric push rod 419 drives the second rack plate 418 to move synchronously, and through the second rack plate 418 meshing with the transmission gear 417, one set of transmission gears 417 is driven to rotate, so that under the action of the meshing connection between the two sets of transmission gears 417, the two sets of transmission gears 417 are driven to rotate, thereby driving the connecting rod 414 to rotate synchronously.

[0056] Furthermore, while the connecting rod 414 rotates, the adjusting rod 415 swings synchronously, so that the adjusting rod 415 controls the first speed change wheel 404 and the second speed change wheel 405 to move closer to or away from each other under the limiting action of the first adjusting groove 4041 and the second adjusting groove 4051, thereby changing the diameter ratio between the driving wheel mechanism and the driven wheel mechanism, and adjusting the transmission ratio of the driving wheel mechanism and the driven wheel mechanism.

[0057] At the same time, through the setting of the connecting rod 414, when the diameter of the driving wheel mechanism is controlled to be smaller, the diameter of the driven wheel mechanism becomes larger, and when the diameter of the driving wheel mechanism is controlled to be larger, the diameter of the driven wheel mechanism becomes smaller. When the diameter of the driving wheel mechanism is larger than the diameter of the driven wheel mechanism, the stirring shaft 107 has a high rotation speed, and when the diameter of the driving wheel mechanism is smaller than the diameter of the driven wheel mechanism, the stirring shaft 107 has a low rotation speed.

[0058] According to the attached Figure 1 , and attached Figure 8 To Attachment Fig.11 As shown, in this embodiment, through the setting of the above-mentioned vibration sensor 200, when the vibration value exceeds the set threshold value, the vibration sensor 200 uploads the signal to the controller 106, and sends a signal to the electric push rod 419 through the controller 106, so as to control the electric push rod 419 so that the electric push rod 419 performs telescopic movement, and controls and adjusts the diameter ratio between the driving wheel mechanism and the driven wheel mechanism so that the diameter of the driving wheel mechanism is smaller than the diameter of the driven wheel mechanism, so that the stirring shaft 107 obtains a low speed, so as to avoid the problem that when the material in the mixing chamber clumps or clumps over a large area, the stirring shaft 107 is affected by the uneven distribution of external raw materials and the increased resistance, resulting in uneven force on the stirring shaft 107 and thus vibration.

[0059] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
