A stirring mechanism of a water and fertilizer integrated device

Abstract

This application relates to the field of water and fertilizer mixing technology, and in particular to a mixing mechanism for an integrated water and fertilizer system. The mechanism includes a mixer body, a drive motor, a drive shaft, a positioning shaft, mixing blades, a liquid inlet pipe, and an electric pump. The drive motor is threaded to the top of the mixer body, and the positioning shaft is movably connected inside the mixer body. The mixing blades are fixedly connected to the outer surfaces of the drive shaft and the positioning shaft, respectively. In this integrated water and fertilizer system, the drive shaft and positioning shaft rotate synchronously via a top meshing gear, causing the multi-layered mixing blades to form a three-dimensional vortex. This forces the bottom material to tumble upwards, preventing sedimentation. Compared to single-shaft mixing, the mixing time is shortened, making it particularly suitable for high-concentration fertilizers. An electric telescopic rod drives the connecting rod downwards, causing a cleaning brush to slide close to the surface of the mixing blades, scraping away adhering substances in real time. A limit spring pushes the inclined slope cleaning brush to adaptively conform to the blade curvature, ensuring thorough cleaning without dead angles.

Description

Technical Field

[0001] This application relates to the field of water and fertilizer mixing technology, and in particular to a mixing mechanism for an integrated water and fertilizer equipment. Background Technology

[0002] The mixing mechanism of fertigation equipment is one of the core components of modern agricultural irrigation systems. Its background technology development mainly revolves around the needs of efficient mixing, anti-clogging, energy saving and environmental protection. In early agriculture, water and fertilizer mixing relied on manual mixing or simple mechanical mixing, which had problems such as uneven mixing, high labor intensity and insufficient fertilizer dissolution.

[0003] A search revealed that CN213434182U discloses a mixing mechanism for an integrated water and fertilizer system. By opening the cover, the water and fertilizer materials can be poured into the bottom of the mixing tank. Then, the control panel turns on the first motor, which drives the rotating rod to rotate, causing the mixing blades to rotate and thus mixing the water and fertilizer materials inside. Next, the control panel turns on the second motor, which drives the threaded rod to rotate stably within the connecting frame. Because the moving block has a threaded hole that matches the threaded rod, and the sliding block and fixed rod are used to restrict the rotation of the moving block, it is pushed up and down by the rotation of the threaded rod, which in turn pushes the inclined rod to rotate horizontally, and then pushes the mixing tank to move left and right. The sliding rail and sliding bar make the movement more stable.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and need to be improved: the aforementioned device uses a stirring shaft to drive several blades to stir the material. The material at the bottom of the device is difficult to dissolve, resulting in poor stirring effect and a long time required for uniform stirring. Furthermore, the stirred material has a certain viscosity and will adhere to the surface of the stirring mechanism of the mixer body, causing insufficient collection when collecting the material. Utility Model Content

[0005] This application provides a mixing mechanism for an integrated water and fertilizer equipment to improve the following technical problems: the above-mentioned device uses a mixing shaft to drive several blades to mix materials. The materials at the bottom of the equipment are difficult to dissolve, resulting in poor mixing effect and long time required for uniform mixing. Moreover, the mixed materials have a certain stickiness and will adhere to the surface of the mixing mechanism of the mixer body, resulting in insufficient collection when collecting materials.

[0006] This application provides a mixing mechanism for an integrated water and fertilizer system, which adopts the following technical solution:

[0007] A mixing mechanism for an integrated water and fertilizer system includes a mixer body, a drive motor, a drive shaft, a positioning shaft, mixing blades, an inlet pipe, and an electric pump. The drive motor is threaded to the top of the mixer body. The top of the drive shaft is fixedly connected to the motor shaft of the drive motor via a coupling. The positioning shaft is movably connected inside the mixer body. The mixing blades are fixedly connected to the outer surfaces of the drive shaft and the positioning shaft, respectively. The inlet pipe penetrates the inner wall of the mixer body and is welded to the surface of the mixer body. The inlet end of the electric pump is fixedly connected to the top of the inlet pipe. A cleaning section is also provided on the top of the mixer body.

[0008] In one feasible technical solution of this application, the cleaning unit includes a support frame, an electric telescopic rod, a connecting rod, and a limiting assembly. The bottom of the support frame is fixedly connected to the top surface of the mixer body. The electric telescopic rod is threadedly connected to one side surface of the support frame. The top of the connecting rod is fixedly connected to the output end of the electric telescopic rod. The top of the limiting assembly is fixedly connected to the bottom of the connecting rod.

[0009] In one feasible technical solution of this application, the limiting component includes a positioning seat, a limiting plate, and a cleaning brush. The positioning seat is slidably sleeved on the outside of the limiting plate. The outer side of the limiting plate is inserted and fixed to the surface of the cleaning brush. The outer side of the cleaning brush is slidably connected to the surface of the stirring blade.

[0010] In one feasible technical solution of this application, the top of the drive shaft and the positioning shaft are provided with mutually meshing limiting gears.

[0011] In one feasible technical solution of this application, the outer side of the limiting plate is configured as a slope surface with an inclined structure.

[0012] In one feasible technical solution of this application, a limiting spring is further provided inside the positioning seat, and the two sides of the limiting spring are fixedly connected to the surfaces of the positioning seat and the limiting abutment, respectively.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] The drive shaft and positioning shaft of this device rotate synchronously via a top meshing gear, driving the multi-layered stirring blades to form a three-dimensional vortex. This forces the material at the bottom to tumble upwards, preventing sedimentation. Compared to single-shaft stirring, the mixing time is shortened, making it especially suitable for high-concentration fertilizers. The electric telescopic rod drives the connecting rod downwards, causing the cleaning brush to slide against the surface of the stirring blades, scraping away adhering substances in real time. The limit spring pushes the inclined slope cleaning brush to adaptively conform to the curvature of the blades, ensuring thorough cleaning without dead angles. Undissolved fertilizer liquid is drawn from the bottom of the mixer and returned to the top through the inlet pipe to form a forced circulation, which, in conjunction with the stirring blades, breaks up the particles.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a mixing mechanism for an integrated water and fertilizer system. (Refer to...) Figures 1 to 5 The mixing mechanism of the integrated water and fertilizer equipment includes a mixer body 1, a drive motor 21, a drive shaft 22, a positioning shaft 23, mixing blades 24, an inlet pipe 25, and an electric pump 26. The drive motor 21 is threaded to the top of the mixer body 1. The top of the drive shaft 22 is fixedly connected to the motor shaft of the drive motor 21 via a coupling. The positioning shaft 23 is movably connected inside the mixer body 1. The mixing blades 24 are fixedly connected to the outer surfaces of the drive shaft 22 and the positioning shaft 23, respectively. The inlet pipe 25 penetrates the inner wall of the mixer body 1 and is welded and fixed to the surface of the mixer body 1. The inlet end of the electric pump 26 is fixedly connected to the top of the inlet pipe 25. A cleaning section 3 is also provided on the top of the mixer body 1.

[0029] The cleaning unit 3 includes a support frame 31, an electric telescopic rod 32, a connecting rod 33, and a limiting component 34. The bottom of the support frame 31 is fixedly connected to the top surface of the mixer body 1. The electric telescopic rod 32 is threadedly connected to one side surface of the support frame 31. The top of the connecting rod 33 is fixedly connected to the output end of the electric telescopic rod 32. The top of the limiting component 34 is fixedly connected to the bottom of the connecting rod 33.

[0030] The limiting component 34 includes a positioning seat 341, a limiting plate 342, and a cleaning brush 343. The positioning seat 341 is slidably sleeved on the outside of the limiting plate 342. The outer side of the limiting plate 342 is inserted and fixed to the surface of the cleaning brush 343. The outer side of the cleaning brush 343 is slidably connected to the surface of the stirring blade 24.

[0031] The top of the drive shaft 22 and the positioning shaft 23 are provided with mutually meshing limit gears 4.

[0032] The outer side of the limiting plate 342 is set as a landslide surface 5 with an inclined structure.

[0033] The positioning seat 341 is also equipped with a limit spring 6 inside, and the two sides of the limit spring 6 are fixedly connected to the surfaces of the positioning seat 341 and the limit plate 342, respectively.

[0034] The general process of using the mixing mechanism of the integrated water and fertilizer equipment in this embodiment is as follows:

[0035] Material is discharged into the mixer body 1 through the feed inlet. At the same time, the drive motor 21 at the top can be started. The drive motor 21 drives the drive shaft 22 to rotate. Through the meshing transmission of the limit gear 4 fixed on the surface of the drive shaft 22 and the positioning shaft 23, the positioning shaft 23 can rotate in the opposite direction of the rotation of the drive shaft 22, thereby disrupting the directional flow of the liquid inside. The stirring blades 24 increase the contact area with the material, thereby enhancing the mixing effect. Since the bottom of the stirring blades 24 does not contact the bottom of the mixer body 1, the material at the bottom of the mixer body 1 is difficult to disperse. This device can use the operating electric liquid pump 26 to suck the deposited material from the feed pipe and circulate it to the top of the mixer body 1, thereby enhancing the dispersion effect of the material. After mixing is complete, the mixing blade 24 is returned to its flat state. Then, the electric telescopic rod 32 at the top of the support frame 31 is activated. The output end of the electric telescopic rod 32 pushes the connecting rod 33, which in turn pushes the positioning seat 341 downward. The outer side of the limiting plate 342 contacts the mixing blade 24 and presses the limiting spring 6 inward. Through the elastic properties of the spring, the limiting plate 342 presses against the cleaning brush 343. With the support of the electric telescopic rod 32, the cleaning of the material adhering to the surface of the mixing blade 24 is completed, making the material collection effect of this device more complete.

[0036] The beneficial technical effects of the mixing mechanism of the integrated water and fertilizer equipment in this application embodiment are roughly as follows:

[0037] The drive shaft 22 and positioning shaft 23 of this device rotate synchronously through a top meshing gear, driving the multi-layer stirring blades 24 to form a three-dimensional vortex, forcing the bottom material to roll upwards and preventing sedimentation. Compared with single-shaft stirring, the mixing time is shortened, making it especially suitable for high-concentration fertilizers. The electric telescopic rod 32 drives the connecting rod 33 to press down, causing the cleaning brush 343 to slide close to the surface of the stirring blades 24, scraping off adhering substances in real time. The limit spring 6 pushes the inclined sliding surface 5 to push the cleaning brush 343 to adapt to the curvature of the blades, ensuring thorough cleaning. Undissolved fertilizer liquid is drawn from the bottom of the mixer and returned to the top through the liquid inlet pipe 25 to form a forced circulation, which works in conjunction with the stirring blades 24 to break up particles.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
