Description

Technical Field

[0001] This invention relates to the field of compounding technology, and in particular to a compounding device for plant growth regulators. Background Technology

[0002] In agricultural planting and production, it is necessary to mix and process various growth agents with different functions according to the growth requirements of plants, so that the mixed agents can exert good efficacy, regulate the soil, and at the same time, plant growth hormones also play a role in cell division and differentiation, fruit development, root formation during cuttings and leaf fall, so as to achieve the purpose of increasing crop yield and improving quality.

[0003] Traditional growth agent mixing is done manually, which has obvious drawbacks and problems such as low efficiency, poor product quality, high labor intensity and high operating costs.

[0004] Currently, a similar large container is used with a stirring device to carry out and complete the mixing of growth agents. The prominent problems are that the structure is bulky and cleaning is extremely inconvenient.

[0005] Meanwhile, when mixing various raw materials, multiple solenoid valves are installed in the middle of the feeding pipe to control the feeding. Since some raw materials of growth hormone are corrosive to metals, they are prone to corroding the internal springs or electronic components of the solenoid valves, leading to leakage. At the same time, when the feeding pipe is connected to various control valves, not only is subsequent inspection difficult, but maintenance is also very demanding.

[0006] Furthermore, existing mixing devices have low mixing efficiency and are prone to creating swirling dead zones, resulting in uneven mixing of some raw materials. Summary of the Invention

[0007] Technical problems to be solved:

[0008] To address the shortcomings of existing technologies, this invention provides a plant growth regulator mixing device, thereby solving the technical problems mentioned in the background section.

[0009] Technical solution:

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A plant growth regulator mixing device includes a mixing tank with raw material hoppers arranged around its top and a mixing device inside. A dispensing plate is fixedly connected to the middle of the mixing tank. The mixing device includes a drive motor with a main shaft at its output end. A stirring rod is located at the lower end of the dispensing plate through the main shaft. The drive motor drives the main shaft to rotate, thereby stirring and mixing various raw materials inside the mixing tank. Multiple raw material hoppers are included. The bottom of each raw material hopper is connected to a lower cavity of the mixing tank separated by the dispensing plate via a flexible hose. Raw materials are delivered to the interior of the mixing tank through the hoses and then stirred by the mixing device to prepare the growth regulator.

[0012] In one possible implementation, the mixing tank is provided with a support leg at the bottom and a bottom cover at the bottom, with the bottom of the bottom cover fixedly connected to the support leg; a top cover is movably provided at the top of the mixing tank, and a drive motor is fixedly connected to the top cover.

[0013] In one possible implementation, a pressure roller is provided on the side of the main shaft near the top of the batching plate. The pressure roller can roll and rotate on the top of the batching plate under the drive of the main shaft. Limiting posts are provided on both sides of the rolling rotation trajectory of the pressure roller on the top of the batching plate. Each hose connected to the raw material hopper crosses the rolling rotation trajectory of the pressure roller and has a section located between the limiting posts. A nozzle is provided at one end of the hose that passes through the batching plate.

[0014] In one possible implementation, the more raw material is inside the raw material hopper, the longer the corresponding hose should be adjusted along the rolling rotation trajectory of the pressure roller.

[0015] In one possible implementation, a discharge pipe is provided at the center of the bottom of the cover, and a valve is provided on the discharge pipe.

[0016] In one possible implementation, a stirring tank is provided on the outside of the stirring rod. The stirring tank includes a second gear. A first gear is fixedly provided at the lower end of the main shaft, and the outer side of the first gear is meshed with the second gear. A gear ring is meshed with the outer side of the second gear, and the outer ring of the gear ring is fixedly connected to the inside of the tank. A spiral plate is fixedly provided on the surface of the tank. Crushing rollers are provided between the tank blades, and the crushing rollers are equally spaced and fixedly connected to the tank. Centrifugal blades are provided between the top of the tank and the bottom cover.

[0017] In one possible implementation, the gear is hollowed out internally.

[0018] In one possible implementation, a rubber plate is provided around the inside of the nozzle, a cross slit is provided in the middle of the rubber plate, and multiple spray holes are provided at the bottom of the nozzle.

[0019] In one possible implementation, the bottom of the barrel has a through hole, and a gear is disposed in the middle of the through hole. The gear, gear, and gear ring are all sealed around the bottom of the barrel.

[0020] In one possible implementation, a second pressure roller is provided on the side of the main shaft corresponding to the first pressure roller.

[0021] Beneficial effects:

[0022] 1. In this scheme, the centrifugal force generated by the rotation of the centrifugal blades drives the raw material mixture in the middle of the bottom of the mixing tank to the bottom and all sides. Then, the rotation of the spiral plate causes the mixture at the bottom to rise along the inner wall of the mixing tank. At the same time, because there are crushing rollers between the spiral plate blades, the mixture is further broken up and stirred a second time as it rises along the wall. Finally, the rising mixture flows back into the mixing tank and is stirred a third time by the stirring rod. Through multiple mixing and stirring, dead zones inside the mixing tank are eliminated, and the various raw materials are fully mixed, further improving the mixing efficiency of the growth agent.

[0023] 2. In this invention, the raw liquid inside the raw material hopper is directly fed into the mixing tank through a hose for mixing, and then the raw liquid is sprayed out by the pressure rollers through a pair of hoses. Compared with the prior art, it does not require valve control, has a simple structure, and is easier to maintain.

[0024] 3. The hose and nozzle of this invention are both made of rubber. Since the main raw material of the growth agent is ethephon, which has a certain corrosive effect on metals, the direct delivery and spraying of the mixture through the hose and nozzle greatly reduces the number of pipelines and valves compared with the existing technology. At the same time, it further prevents leakage at pipe joints and reduces the risk of corrosion.

[0025] 4. The present invention has a pressure roller two on the side of the main shaft corresponding to the pressure roller one; so that when the main shaft rotates, the pressure roller one and the pressure roller two will also rotate synchronously to squeeze the hose below the motion trajectory; on the one hand, it improves the feeding rate of the growth agent mixture, and on the other hand, it provides operational support when some raw materials need to be added at the same time to react and generate derivatives in the preparation of some growth factors.

[0038] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can also be implemented in various different forms, and therefore the present invention is not limited to the embodiments described below. In addition, for the purpose of more clearly describing the present invention, parts not connected to the invention will be omitted from the drawings.

[0039] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0040] Example 1:

[0041] like Figure 1 , 2As shown in the figure, this embodiment introduces the specific structure of a plant growth regulator mixing device, including a support leg 1, a mixing tank 2 on the top of the support leg 1, a raw material hopper 4 around the top of the mixing tank 2, and a mixing device 3 inside the mixing tank 2; a bottom cover 21 is provided at the bottom of the mixing tank 2, and the bottom of the bottom cover 21 is fixedly connected to the support leg 1; a top cover 22 is movably provided at the top of the mixing tank 2, and a batching plate 24 is fixedly connected to the middle of the mixing tank 2;

[0042] The mixing device 3 includes a drive motor 31, which is fixedly connected to the top cover 22. A main shaft 32 is provided at the output end of the drive motor 31. The main shaft 32 passes through the lower end of the mixing plate 24 and a stirring rod 33 is provided thereon. The drive motor 31 drives the main shaft 32 to rotate, thereby driving the main shaft 32 to stir and mix various raw materials inside the mixing tank 2. There are multiple raw material hoppers 4, which are used to store the raw materials required for the production of the growth agent. The bottom of the raw material hopper 4 is connected to the mixing tank 2 and the mixing plate 24 through a hose 41, and communicates with the lower cavity of the mixing tank 2 separated by the mixing plate 24. The raw materials are transported into the mixing tank 2 through the hose 41 and then stirred by the mixing device 3 to realize the preparation of the growth agent.

[0043] like Figure 5 , 6 As shown, a pressure roller 34 is provided on the side of the main shaft 32 near the top of the feeding plate 24. The pressure roller 34 can roll and rotate on the top of the feeding plate 24 under the drive of the main shaft 32. Limiting posts 242 are provided on both sides of the rolling rotation trajectory of the pressure roller 34 on the top of the feeding plate 24. Each hose 41 connected to the raw material hopper 4 crosses the rolling rotation trajectory of the pressure roller 34, and a section is located between the limiting posts 242. A nozzle 42 is provided at one end of the hose 41 that passes through the feeding plate 24. When the raw material enters the hose 41 under the action of gravity, a nozzle 42 is provided on the end of the hose 41. At the lower end of 1, the main shaft 32 drives the pressure roller 34 to rotate. At this time, the pressure roller 34 squeezes the hose 41. The raw material inside the hose 41 will flow towards the nozzle 42 under the squeezing action of the pressure roller 34. When a certain pressure is reached, the raw material inside the hose 41 will be sprayed out from the corresponding nozzle 42. The raw material is transported to the inside of the mixing tank 2 by spraying, so that the various raw materials are more uniform in the mixing process. At the same time, after being squeezed by the pressure roller 34, the raw material inside the hose 41 will continue to be replenished under the action of gravity.

[0044] The more raw materials are inside the raw material hopper 4, the longer the corresponding hose 41 should be on the rolling rotation trajectory of the pressure roller 34. When the hose 41 is longer on the movement trajectory of the pressure roller 34, the amount of raw material extruded each time also increases accordingly. Therefore, by changing the length of the hose 41 on the movement trajectory of the pressure roller 34, the mixing ratio of different raw materials can be adjusted.

[0045] The feed plate 24 has a clearance hole 241 in the middle, through which the main shaft 32 passes;

[0046] like Figure 3 As shown, in one possible implementation, the support leg 1 has multiple legs, and each support leg 1 is fixedly connected to each other by a rib plate 11, thereby reinforcing the bottom of the entire device;

[0047] like Figure 2 As shown, in one possible implementation, a feeding pipe 23 is provided at the center of the bottom of the bottom cover 21, and a valve is provided on the feeding pipe 23. The feeding is carried out by opening or closing the valve.

[0048] like Figure 1 As shown, in one possible implementation, the top cover 22 is connected to the mixing tank 2 by screws;

[0049] like Figure 2 , 4 As shown in Figure 7, a stirring tank 5 is provided on the outside of the stirring rod 33. The stirring tank 5 includes a second gear 51. A first gear 35 is fixedly provided at the lower end of the main shaft 32. The outer side of the first gear 35 is meshed with the second gear 51. A gear ring 52 is meshed with the outer side of the second gear 51. The outer ring of the gear ring 52 is fixedly connected to the inside of the tank body 53. A spiral plate 54 is fixedly provided on the surface of the tank body 53. Crushing rollers 55 are provided between the blades of the tank body 53. The crushing rollers 55 are evenly spaced and fixedly connected to the tank body 53. Centrifugal blades 56 are provided between the top of the tank body 53 and the bottom cover 21.

[0050] When the raw materials flow into the mixing tank 2, they are first stirred and mixed by the stirring rod 33. However, since the stirring method of the stirring rod 33 is relatively traditional and the direction is fixed, it is easy to create dead zones in the stirring. In this invention, while the stirring rod 33 is stirring, the main shaft 32 drives the gear 2 51 to rotate through the gear 1 35, and then drives the gear ring 52 to rotate through the gear 2 51, thereby realizing the rotation of the tank body 53. Since the bottom of the tank body 53 is provided with centrifugal blades 56, the centrifugal force generated by the rotation of the centrifugal blades 56 drives the raw material mixture in the middle of the bottom of the mixing tank 2 to the bottom and all sides. Then, the rotation of the spiral plate 54 pushes the mixture at the bottom to rise along the inner wall of the mixing tank 2. At the same time, since the blades of the spiral plate 54 are provided with crushing rollers 55, as the mixture rises along the wall, it is broken and stirred a second time by the crushing rollers 55. Finally, the rising mixture flows back into the mixing tank 5 and is stirred a third time by the stirring rod 33. In this way, through multiple mixing and stirring, the dead zones in the mixing tank 2 are eliminated, and the various raw materials are fully mixed, further improving the mixing efficiency of the growth agent.

[0051] like Figure 7 As shown, in one possible implementation, the gear 35 is hollow inside, allowing the mixed growth agent to flow out during material feeding;

[0052] like Figure 2 and 7 As shown, in one possible implementation, the bottom of the barrel 53 has a through hole 57, and a gear 35 is disposed in the middle of the through hole 57. The gear 35, the gear 51 and the gear ring 52 are all sealed around the bottom of the barrel 53.

[0053] like Figure 8 and 9 As shown, the nozzle 42 has rubber plates 421 arranged around its interior, with a cross slit 422 in the center of each rubber plate 421. Multiple spray holes 423 are located at the bottom of the nozzle 42. The rubber plates 421 have a certain elasticity. When the raw material liquid inside the hose 41 is not under external pressure, the rubber plates 421 are tightly fitted together, preventing the raw material from falling. When the raw material inside the hose 41 is squeezed by the pressure roller 34, it flows towards the nozzle 42. When a certain pressure is reached, it lifts the rubber plates 421, opening the cross slit 422, and the raw material inside the hose 41 is sprayed out from the corresponding nozzle 42. The raw material liquid inside the raw material hopper 4 is directly fed into the mixing tank 2 through the hose 41 for mixing, and then squeezed by the pressure roller 34, causing the raw material to be sprayed. Compared with existing technologies, this design eliminates the need for valve control, simplifies the structure, and makes maintenance more convenient.

[0054] Furthermore, both hose 41 and nozzle 42 are made of rubber. Since the main raw material of the growth agent is ethephon, which has a certain corrosive effect on metals, direct delivery and spraying through hose 41 and nozzle 42 greatly reduces the number of pipelines and valves compared with existing delivery technologies. At the same time, it further prevents leakage at pipe joints and reduces the risk of corrosion.

[0055] Example 2:

[0056] This embodiment is an improvement based on Embodiment 1;

[0057] like Figure 10 As shown, a pressure roller 36 is provided on the side of the main shaft 32 corresponding to the pressure roller 34; thus, when the main shaft 32 rotates, the pressure roller 34 and the pressure roller 36 will also rotate synchronously to squeeze the hose 41 below the motion trajectory; on the one hand, it improves the feeding rate of the growth agent mixture, and on the other hand, it provides operational support when some raw materials need to be added at the same time to react and generate derivatives in the preparation of some growth factors.

[0058] When the growth regulator is prepared, the raw materials do not react with each other; simply add the various raw materials to the raw material hopper 4, and squeeze the hose 41 below the motion trajectory by synchronously rotating the raw material hopper 4 and the pressure roller 36; thus improving the feeding rate of the growth regulator mixture.

[0059] When two raw materials are required to react and produce derivatives during the preparation of the growth regulator, the two raw materials are stored inside the raw material hopper 4. When the drive motor 31 is started, the drive motor 31 drives the main shaft 32 to rotate, and the pressure roller 1 34 and pressure roller 2 36 will rotate synchronously. Since the two raw liquids are symmetrically stored inside the raw material hopper 4, the pressure roller 1 34 and pressure roller 2 36 will squeeze the hoses 41 corresponding to the two raw liquids. In this way, the two raw liquids will be sprayed out from their respective nozzles 42 at the same time. The two atomized raw liquids will react fully and produce derivatives. Then, the stirring described in Example 1 is performed, and finally, the product is discharged from the discharge pipe 23.

[0060] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
