Description

Technical Field

[0002] The research and development of key technologies for compound plant growth regulators in increasing crop yields is crucial. The production of compound plant growth regulators will utilize a modulation kettle for mixing production.

[0003] For example, in the prior art: CN221156278U, which discloses a modulation kettle for plant growth regulator production. In this prior art, while the rotating shaft rotates, the base provided at the upper end of the rotating shaft can cooperate with the cleaning brush to clean the upper end surface of the modulation kettle body, avoiding the problem that raw materials adhere to the upper end of the modulation kettle body and are not easily poured out.

[0004] However, the inventor found that the following problems exist when using this prior art: In the prior art, the cleaning brush is exposed above the base. This causes that during the mixing process of the plant growth regulator by the mixing device, in addition to splashing and adhering to the upper end surface of the modulation kettle body, it will inevitably adhere to the cleaning brush, affecting the cleanliness of the bristles of the cleaning brush. If the cleaning brush is not cleaned, these raw materials will agglomerate on the surface of the cleaning brush, thereby affecting the cleaning effect of the upper end surface of the modulation kettle body, resulting in unclean cleaning inside the modulation kettle and affecting the quality of the subsequent mixing of the compound nutrient plant growth regulator.

[0020] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the sake of description, only the parts related to the invention are shown in the drawings.

[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0022] Please refer to Figures 1 - 3 , the present invention provides a technical solution of the first embodiment: Specifically, it refers to a mixing device for preparing a compound nutrient plant growth regulator, including a mixing kettle body 1. A stirring shaft 2 is rotatably connected to the top wall of the mixing kettle body 1. A plurality of stirring rods 3 for stirring the regulator raw materials are arranged on the outer surface of the stirring shaft 2. A driving component 6 for controlling the rotation of the stirring shaft 2 is arranged at the top of the mixing kettle body 1; On the outer surface of the top of the stirring shaft 2, a plurality of bases 4 arranged in a circumferential array are provided. A shrinkage groove 7 is formed on the upper surface of the base 4. A bottom plate 8 is slidably installed in the shrinkage groove 7. The outer surface of the bottom plate 8 fits with the inner wall of the shrinkage groove 7. On the upper surface of the bottom plate 8, a cleaning brush 9 capable of cleaning the top wall of the mixing kettle body 1 is provided. There is a certain distance between the top of the cleaning brush 9 and the upper surface of the base 4. On the upper surface of the base 4, a foldable top cover 5 for covering the top of the shrinkage groove 7 is provided. When in use, when it is necessary to clean the top wall of the mixing kettle body 1, the foldable top cover 5 is opened. At this time, the bottom plate 8 is controlled to move upward, and the cleaning brush 9 extends out of the upper surface of the base 4 through the shrinkage groove 7. When the upper surface of the bottom plate 8 is flush with the upper surface of the base 4, the top of the cleaning brush 9 contacts the top wall of the mixing kettle body 1. At this time, only by rotating the stirring shaft 2 again, the base 4 will rotate synchronously with the stirring shaft 2, so that the cleaning brush 9 can clean the top wall of the mixing kettle body 1. When cleaning is not required, since the foldable top cover 5 covers the shrinkage groove 7, during the mixing process of the plant growth regulator, the regulator raw materials will not splash onto the cleaning brush 9. In this way, the cleanliness of the cleaning brush 9 during long-term use of the mixing device is ensured, the cleaning effect of the cleaning brush 9 on the top of the mixing kettle body 1 is ensured, and the problem that part of the regulator raw materials adhere to the top wall of the mixing kettle body 1 and cause unclean cleaning is avoided as much as possible, and the quality of the mixing of the compound nutrient plant growth regulator in the later stage is guaranteed.

[0023] The driving assembly 6 includes a motor 61. The motor 61 is installed on the upper surface of the mixing kettle body 1. A first bevel gear 62 is sleeved on the output shaft of the motor 61. The upper end of the stirring shaft 2 rotates through the upper surface of the mixing kettle body 1. A second bevel gear 63 meshed with the first bevel gear 62 is sleeved on the outer surface of the upper end of the stirring shaft 2. When in use, the motor 61 is started, and the output shaft of the motor 61 drives the first bevel gear 62 to rotate synchronously. The second bevel gear 63 rotates synchronously under the meshing drive of the first bevel gear 62, and the stirring shaft 2 rotates synchronously with the second bevel gear 63. Thus, when different raw materials of the plant growth regulator are poured into the mixing kettle body 1, the stirring shaft 2 drives the stirring rod 3 to stir and mix the raw materials in the mixing kettle body 1.

[0024] An active rod 10 is arranged on the upper surface of the stirring shaft 2. An extrusion cavity 12 is formed in the stirring shaft 2. The lower end of the active rod 10 movably penetrates into the extrusion cavity 12. When the stirring shaft 2 rotates, the stirring shaft 2 can rotate on the outer surface of the active rod 10, and the active rod 10 remains stationary. When the active rod 10 moves, it can slide up and down on the stirring shaft 2. A screw rod 17 is arranged at the upper end of the active rod 10. An n-shaped frame 18 is arranged on the upper surface of the mixing kettle body 1. The second bevel gear 63 is arranged between the two vertical plates of the n-shaped frame 18. The upper end of the screw rod 17 threadedly penetrates through the upper surface of the cross plate of the n-shaped frame 18. When in use, by rotating the screw rod 17, the screw rod 17 can drive the active rod 10 to move up and down under the transmission of the thread.

[0025] At the lower end of the movable rod 10, there is an extrusion block 16 in the shape of a combination of a cylinder and an inverted cone. At the bottom of the contraction groove 7, there is a first push rod 11. One end of the first push rod 11 penetrates into the extrusion cavity 12. Slide holes communicating with the contraction groove 7 and the extrusion cavity 12 are respectively formed in the base 4 and the stirring shaft 2. The first push rod 11 slides in the slide hole. One end of the first push rod 11 located in the extrusion cavity 12 contacts the outer surface of the extrusion block 16. A first rotating plate 13 is hinged between one end of the first push rod 11 located in the contraction groove 7 and the lower surface of the bottom plate 8. A sleeve plate 14 is sleeved on the outer surface of the first push rod 11 located in the contraction groove 7. A first tension spring 15 that is movably sleeved on the outer surface of the first push rod 11 is arranged between the sleeve plate 14 and the inner wall of the contraction groove 7. When the first tension spring 15 is not affected by the pulling force, the first tension spring 15 will form a pulling force on the sleeve plate 14, making the sleeve plate 14 on the side close to the stirring shaft 2. At the same time, most of the end of the first push rod 11 close to the stirring shaft 2 extends into the extrusion cavity 12, and the first rotating plate 13 pulls the bottom plate 8 to displace to the bottom of the contraction groove 7. At this time, the cleaning brush 9 retracts into the contraction groove 7.

[0026] During use, by rotating the screw rod 17 and pushing the movable rod 10 to displace downward, at this time, the extrusion block 16 synchronously displaces downward with the movable rod 10. Since the shape of the extrusion block 16 is a combination of a cylinder and an inverted cone, the conical outer surface at the bottom of the extrusion block 16 will act on the first push rod 11, making the first push rod 11 displace to the side in the contraction groove 7. At the same time, the sleeve plate 14 pulls the first tension spring 15, making the first tension spring 15 stretch. At this time, the first rotating plate 13 will form an upward thrust on the bottom plate 8, making the bottom plate 8 push the cleaning brush 9 to displace upward. When the cylindrical outer surface of the extrusion block 16 contacts the first push rod 11, the bottom plate 8 is pushed to displace to the longest distance. At this time, the upper surface of the bottom plate 8 is flush with the upper surface of the base 4, and the cleaning brush 9 contacts the top wall of the mixing kettle body 1. When the screw rod 17 is rotated in the reverse direction, the movable rod 10 displaces upward. At this time, the extrusion block 16 no longer extrudes the first push rod 11, and the first tension spring 15 loses its restriction and gradually pulls the first push rod 11 to displace to the initial position. At this time, the first rotating plate 13 pulls the bottom plate 8 to displace downward until the cleaning brush 9 retracts into the contraction groove 7 again. With the above structure, the extension or contraction of the cleaning brush 9 can be controlled outside the mixing kettle body 1, reducing the difficulty of controlling the cleaning brush 9.

[0027] In addition, since the existing cleaning brush 9 is generally made of a material that will bend when being extruded, if the cleaning brush 9 displaces upward and the foldable top cover 5 covers the contraction groove 7, it is difficult for the cleaning brush 9 to push open the foldable top cover 5.

[0028] Figures 4 - 5 The second embodiment is shown, which is a variant of the first embodiment and mainly solves the problem that it is difficult for the cleaning brush 9 to push open the foldable top cover 5.

[0029] Specifically, the foldable top cover 5 includes a first cover plate 51 and a second cover plate 52. The first cover plate 51 and the second cover plate 52 are horizontally arranged and cover the upper side of the base 4. Two parallel mounting seats 53 are provided on the upper surface of the base 4. The two mounting seats 53 are respectively arranged on opposite sides of the end of the first cover plate 51 far from the second cover plate 52. A first rotating shaft 54 rotatably connected to the mounting seat 53 is provided on the surface of the first cover plate 51 close to the mounting seat 53. The interior of the mounting seat 53 close to the stirring shaft 2 is hollow. One end of the first rotating shaft 54 close to the stirring shaft 2 rotatably penetrates into the mounting seat 53. A worm gear 55 is sleeved on the outer surface of the end of the first rotating shaft 54 located inside the mounting seat 53. A worm 56 meshed with the worm gear 55 is rotatably connected to the top wall of the mounting seat 53. During use, by controlling the rotation of the worm 56, at this time the worm gear 55 rotates synchronously under the meshing drive of the worm 56, and the first rotating shaft 54 rotates synchronously with the worm gear 55. At this time, the first cover plate 51 and the second cover plate 52 can be driven to rotate upward and no longer cover the contraction groove 7.

[0030] A first inner cavity 58 is opened in the inner side of the base 4 close to the stirring shaft 2. A transmission shaft 57 is provided at the lower end of the worm 56. The lower end of the transmission shaft 57 rotatably penetrates into the first inner cavity 58. A first gear 59 is sleeved on the outer surface of the lower end of the transmission shaft 57. A first rack 510 is meshed with the outer surface of the first gear 59. A sliding groove 514 is opened on one side of the sliding hole close to the first inner cavity 58. An extrusion plate 513 sliding in the sliding groove 514 is provided on the outer surface of the first push rod 11. The shape of the extrusion plate 513 is a right trapezoid. A second push rod 511 is provided on the surface of the first rack 510 facing the sliding groove 514. The other end of the second push rod 511 slidably penetrates into the sliding groove 514 and contacts the extrusion plate 513. A second tension spring 512 sleeved on the outer surface of the second push rod 511 is provided between the first rack 510 and the inner wall of the first inner cavity 58.

[0031] During use, when the first push rod 11 displaces towards one side of the contraction groove 7, the extrusion plate 513 will displace synchronously with the first push rod 11. At this time, the inclined surface of the extrusion plate 513 will exert extrusion on the second push rod 511, causing the second push rod 511 to displace towards one side of the first inner cavity 58. The first rack 510 displaces synchronously with the second push rod 511. At the same time, the second tension spring 512 is stressed and stretched. The first rack 510 drives the first gear 59 to rotate synchronously. The worm 56 rotates with the transmission shaft 57. Therefore, the rotation of the first rotating shaft 54 is controlled. At this time, the first cover plate 51 and the second cover plate 52 rotate synchronously with the first rotating shaft 54. When the second push rod 511 slides from the inclined surface of the extrusion plate 513 to the vertical surface, the first rack 510 displaces to the longest distance, and the first cover plate 51 and the second cover plate 52 rotate to 90 degrees and no longer block the contraction groove 7. When the first push rod 11 continuously pushes the cleaning brush 9 to displace upwards, since the extrusion plate 513 is a right trapezoid, the second push rod 511 always slides on the vertical surface of the extrusion plate 513, so that the second push rod 511 can be continuously restricted, preventing the situation that the second tension spring 512 pulls the second push rod 511 to displace, ensuring the stability of the rotation of the first cover plate 51 and the second cover plate 52. Through the above structure, the foldable top cover 5 can be automatically controlled to open during the process of pushing the cleaning brush 9 upwards, avoiding as much as possible the situation that it is difficult for the cleaning brush 9 to push open the foldable top cover 5, and ensuring the cleaning effect on the top wall of the mixing kettle body 1.

[0032] In addition, since the diameter of the existing stirring shaft 2 is generally small, it can be known that the diameter of the extrusion block 16 is also small, which results in a short upward displacement distance of the cleaning brush 9. To ensure that the cleaning brush 9 can contact the top wall of the mixing kettle body 1, the base 4 needs to be set closer to the top wall of the mixing kettle body 1. If the length of the first cover plate 51 and the second cover plate 52 is long when they are turned upwards, it will cause the second cover plate 52 to hit the top wall of the mixing kettle body 1, resulting in a problem of mechanical jamming.

[0033] Figure 5 And Figure 7 The third embodiment is shown, which is a variant of the second embodiment, mainly solving the situation that the first cover plate 51 and the second cover plate 52 may hit the top wall of the mixing kettle body 1 during the upward bending process.

[0034] Specifically, one side of the first cover plate 51 close to the second cover plate 52 is concave, while one side of the second cover plate 52 close to the first cover plate 51 is convex. The protruding part of the second cover plate 52 extends into the concave part of the first cover plate 51. Second rotating shafts 5102 rotatably connected to the inner side surface of the first cover plate 51 are arranged on both opposite side surfaces of the protruding part of the second cover plate 52. A second inner cavity 5101 is formed in the first cover plate 51. One end of the second rotating shaft 5102 close to the second inner cavity 5101 rotatably penetrates into the second inner cavity 5101. A second gear 5103 is sleeved on the outer surface of one end of the second rotating shaft 5102 located in the second inner cavity 5101. A second rack 5104 is meshed and connected to the top of the second gear 5103. A third push rod 5105 is arranged on the surface of the second rack 5104 facing away from the second cover plate 52. The other end of the third push rod 5105 slidably penetrates out of the surface of the first cover plate 51 away from the second cover plate 52. A third tension spring 5106 movably sleeved on the outer surface of the third push rod 5105 is arranged between the second rack 5104 and the inner wall of the second inner cavity 5101. An arc-shaped plate 5107 is arranged on the surface of the base 4 close to the extended end of the third push rod 5105. The extended end of the third push rod 5105 is in contact with the arc-shaped surface of the arc-shaped plate 5107.

[0035] During use, when the first cover plate 51 rotates upward, the third push rod 5105 rotates synchronously with the first cover plate 51. At this time, the third push rod 5105 is squeezed by the arc-shaped surface of the arc-shaped plate 5107, so that the third push rod 5105 displaces towards the inner side of the second inner cavity 5101, the second rack 5104 displaces synchronously, and the third tension spring 5106 is stretched. At this time, the second rack 5104 can drive the second gear 5103 to rotate clockwise through meshing transmission, and the second rotating shaft 5102 drives the second cover plate 52 to rotate downward and fold up synchronously. When the first cover plate 51 rotates 90 degrees, the bending angle of the second cover plate 52 is the largest, and the second cover plate 52 and the first cover plate 51 form an acute angle. With the above structure, the second cover plate 52 can be automatically controlled to bend when the first cover plate 51 rotates upward, effectively avoiding the problem that the second cover plate 52 impacts the top wall of the mixing kettle body 1 and ensuring the effect of opening the first cover plate 51.

[0036] At the same time, since there is a certain distance between the top of the cleaning brush 9 and the upper surface of the base 4, when the brush extends upward, the first cover plate 51 and the second cover plate 52 can quickly rotate to 90 degrees and can be bent, preventing the problem of clamping the brush during the bending process.

[0037] In addition, when the cleaning brush 9 cleans the top wall of the mixing kettle body 1, raw materials will inevitably adhere to its bristles. If the cleaning brush 9 is directly retracted into the base 4, after long-term use, these raw materials will caking on the cleaning brush 9, affecting the cleaning effect of the cleaning brush 9 on the top wall of the mixing kettle body 1. At the same time, if the caked raw materials on the cleaning brush 9 fall onto the plant growth regulator being mixed, it will affect the mixing quality of the plant growth regulator.

[0038] Figure 2 And Figure 8 The fourth embodiment is shown, which is a variant of the third embodiment, mainly solving the problem of raw materials adhering to the cleaning brush 9.

[0039] Specifically, a pushing component 515 for controlling the back-and-forth displacement of the second push rod 511 is arranged on the vertical surface of the pressing plate 513 facing the second push rod 511. The pushing component 515 includes a retracting plate 5151. A reset groove 5152 is formed on the vertical surface of the pressing plate 513. The retracting plate 5151 slides in the reset groove 5152. A third inner cavity 5153 is formed in the first push rod 11. A fourth push rod 5154 is arranged on the surface of the retracting plate 5151 facing the third inner cavity 5153. The other end of the fourth push rod 5154 slides through and extends into the third inner cavity 5153. A fourth tension spring 5155 is movably sleeved on the outer surface of the fourth push rod 5154 between the retracting plate 5151 and the inner wall of the reset groove 5152. When the fourth tension spring 5155 is not affected by the pulling force, the fourth tension spring 5155 will form a pulling force on the retracting plate 5151, so that the initial position of the retracting plate 5151 is to retract a short distance into the reset groove 5152.

[0040] An extrusion rod 5156 is arranged in the third inner cavity 5153. One end of the extrusion rod 5156 is hinged with a second rotating plate 5157 with the fourth push rod 5154. The other end of the extrusion rod 5156 slides through the first push rod 11 and extends into the extrusion cavity 12 to contact the extrusion block 16. A plurality of hemispherical grooves 5158 arranged in a circumferential array are formed on the cylindrical outer surface of the extrusion block 16. The diameter of the groove 5158 is smaller than the diameter of the first push rod 11. Therefore, the groove 5158 will not affect the sliding of the first push rod 11. When the stirring shaft 2 rotates, the extrusion rod 5156 can slide into the groove 5158.

[0041] During use, when the first push rod 11 pushes the cleaning brush 9 upward, since the first push rod 11 is pushed and displaced by the extrusion block 16, at this time, the inclined surface of the cone of the extrusion block 16 contacts the top surface of the end in contact with the first push rod 11, which will not affect the extended part of the extrusion rod 5156. At the same time, the second push rod 511 slides from the inclined surface of the extrusion plate 513 to the vertical surface. When the first push rod 11 slides onto the cylindrical surface of the extrusion block 16, the extrusion rod 5156 is extruded by the cylindrical surface of the extrusion block 16, causing the extrusion rod 5156 to displace into the third inner cavity 5153. The second rotating plate 5157 exerts a thrust on the fourth push rod 5154, causing the shrinkage plate 5151 to displace outward until the outer surface of the shrinkage plate 5151 is flush with the vertical surface of the extrusion plate 513. At the same time, the second push rod 511 slides into the reset groove 5152 and contacts the surface of the shrinkage plate 5151. Since the outer surface of the shrinkage plate 5151 is flush with the vertical surface of the extrusion plate 513, it can still block the second push rod 511. When the stirring shaft 2 rotates, since the movable rod 10 and the extrusion block 16 remain stationary, the first push rod 11 and the extrusion rod 5156 slide on the cylindrical surface of the extrusion block 16. When the extrusion rod 5156 slides into the groove 5158, the fourth tension spring 5155 loses its pulling force. At this time, the fourth tension spring 5155 can pull the shrinkage plate 5151 to displace a short distance into the reset groove 5152, and the second push rod 511 will displace a certain distance to one side of the sliding groove 514 under the pulling of the second tension spring 512. At this time, it can drive the first cover plate 51 to rotate inward. At the same time, the third push rod 5105 rotates synchronously during the rotation of the first cover plate 51. Therefore, the third tension spring 5106 can pull the second rack 5104 to displace, and at this time, it can drive the second cover plate 52 to rotate counterclockwise and contact the cleaning brush 9. Since the number of grooves 5158 is set to be multiple, during the rotation of the stirring shaft 2, the first cover plate 51 and the second cover plate 52 can rotate repeatedly in small amplitudes, so as to form a continuous knocking effect on the cleaning brush 9, so that the raw materials attached to the cleaning brush 9 can be shaken off into the mixing kettle body 1, ensuring the use effect of the cleaning brush 9 during long-term use and minimizing the impact on the mixing quality of the plant growth regulator when the caked raw materials on the cleaning brush 9 fall onto the plant growth regulator being mixed.

[0042] In the present invention, the side of the reset groove 5152 facing away from the first push rod 11 is arranged in a flared shape. In this way, when the extrusion rod 5156 is displaced into the groove 5158 and the shrinkage plate 5151 is in a state of being displaced into the reset groove 5152, and when the extrusion plate 513 is displaced towards the stirring shaft 2, the second push rod 511 can slide onto the vertical surface of the extrusion plate 513 through the inclined surface of the reset groove 5152, and there will be no problem of mechanical jamming. At the same time, when the shrinkage plate 5151 is squeezed to be flush with the vertical surface of the extrusion plate 513, the distance between the surface of the shrinkage plate 5151 and the edge position of the reset groove 5152 is less than the diameter of the second push rod 511. Therefore, the second push rod 511 will not be stuck between the shrinkage plate 5151 and the reset groove 5152.

[0043] The present invention provides a new technical solution: a compound nutrient plant growth regulator, which is prepared by selecting 1-5 parts (by weight) of gibberellin, 10-30 parts (by weight) of sodium naphthylacetate, 1-5 parts (by weight) of ethephon, 10-30 parts (by weight) of organic matter, 1-5 parts (by weight) of trace elements and a certain amount of water, pouring them into a mixing kettle body and stirring and mixing them. The prepared compound nutrient plant growth regulator can promote seed germination and plant growth, as well as promote rooting and crop growth.

Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
