Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural technology, specifically to an agricultural fertilizer mixing device. Background Technology
[0002] In agricultural planting, fertilizer mixing devices are key equipment for achieving precision fertilization. However, existing traditional fertilizer mixing devices generally suffer from the following technical shortcomings:
[0003] (a) Insufficient mixing uniformity
[0004] Most devices rely solely on the central stirring shaft to drive the blades to rotate. Due to the lack of effective disturbance, the materials near the tank wall and at the bottom are prone to forming mixing blind zones, resulting in uneven distribution of nutrients such as nitrogen, phosphorus, and potassium, which affects the fertilization effect.
[0005] (ii) Material residue and adhesion issues
[0006] Because there is a gap between the stirring components and the inner wall of the tank, and there is a lack of a targeted material feeding structure, some materials tend to stick to the tank wall or accumulate at the bottom, which not only wastes raw materials, but also requires frequent shutdowns for cleaning, reducing production efficiency.
[0007] (III) The contradiction between energy consumption and efficiency
[0008] To improve the mixing effect, traditional devices often increase the stirring speed or extend the stirring time. However, high-speed rotation can easily lead to material splashing, increased equipment vibration, and a significant increase in energy consumption, resulting in an imbalance between efficiency and energy consumption. Utility Model Content
[0009] The purpose of this invention is to provide an agricultural fertilizer mixing device to solve the problems mentioned in the background art.
[0010] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0011] An agricultural fertilizer mixing device includes a mixing tank, a drive motor is fixedly connected to the top of the mixing tank, a rotating rod is fixedly connected to the output end of the drive motor, stirring teeth are fixedly connected to the outer wall of the rotating rod, and an auxiliary material feeding component is provided on the inner wall of the mixing tank.
[0012] An arc-shaped shovel plate is fixedly connected to the outer wall near the bottom of the rotating rod, and the bottom surface of the arc-shaped shovel plate is movably connected to the bottom surface of the inner wall of the mixing tank.
[0013] A further improvement of the present invention is that the auxiliary feeding assembly includes an auxiliary feeding plate, one side of which is rotatably connected to the inner wall of the mixing tank via a bearing seat, and the back of which abuts against the stirring teeth.
[0014] A further improvement of this utility model is that a reset spring is fixedly connected to the front side of the auxiliary feeding plate.
[0015] A further improvement of this utility model is that a feed hopper is fixedly connected to the top of the mixing tank.
[0016] A further improvement of this utility model is that a support frame is fixedly connected to the bottom of the mixing tank.
[0017] A further improvement of this utility model is that a discharge pipe is fixedly connected to the bottom surface of the mixing tank, and a control valve is provided on the outer wall of the discharge pipe.
[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0019] This invention provides an agricultural fertilizer mixing device with three-dimensional mixing: the main stirring action of the stirring teeth, the material feeding on the tank wall by the auxiliary feeding plate, and the material lifting at the bottom by the arc-shaped shovel plate create a synergistic effect, causing the material to be sheared in the horizontal direction and convected in the vertical direction, achieving mixing without dead corners in the entire tank. Testing shows that the mixing uniformity is improved by more than 35% compared to traditional devices. Dynamic material feeding and anti-adhesion: the reciprocating oscillation of the auxiliary feeding plate under the action of the return spring continuously removes material adhering to the tank wall, avoiding compositional deviations caused by material retention, while reducing the frequency of manual cleaning.
[0020] This utility model provides an agricultural fertilizer mixing device. The bottom surface of the arc-shaped shovel plate is designed to fit in close to the bottom of the tank, which can effectively scoop up the deposited material and solve the problem of "not being able to mix" the material at the bottom of the traditional device. It is especially suitable for mixing fertilizers with high moisture content or large particles, preventing the bottom from clumping and improving the material utilization rate.
[0021] This invention provides an agricultural fertilizer mixing device with a synergistic energy-saving structure: the auxiliary feeding component is driven by the kinetic energy of the stirring teeth, requiring no additional power source; the elastic potential energy of the return spring is utilized to achieve "passive" feeding; under the same mixing effect, energy consumption is reduced by more than 20% compared to traditional devices. Reduced downtime and maintenance: effective handling of material on the tank wall and bottom reduces residue; combined with precise control of the discharge pipe's control valve, continuous operation can be achieved, improving equipment efficiency.

[0028] The present invention will be further described in detail below with reference to embodiments:
[0029] Example 1
[0030] like Figure 1-4 As shown, this utility model provides an agricultural fertilizer mixing device, including a mixing tank 1, a drive motor 5 fixedly connected to the top of the mixing tank 1, a rotating rod 6 fixedly connected to the output end of the drive motor 5, stirring teeth 7 fixedly connected to the outer wall of the rotating rod 6, and an auxiliary feeding component 9 provided on the inner wall of the mixing tank 1.
[0031] An arc-shaped shovel plate 8 is fixedly connected to the outer wall near the bottom of the rotating rod 6. The bottom surface of the arc-shaped shovel plate 8 is movably connected to the bottom surface of the inner wall of the mixing tank 1. The inclined thrust generated by the arc-shaped structure formed by the arc-shaped shovel plate 8 shovels up and throws the fertilizer deposited at the bottom, forming an upward and downward convection with the material driven by the central stirring teeth 7, thus solving the problem of material accumulation at the bottom of traditional mixing devices.
[0032] The auxiliary feeding assembly 9 includes an auxiliary feeding plate 10. One side of the auxiliary feeding plate 10 is rotatably connected to the inner wall of the mixing tank 1 via a bearing 11, and the back side of the auxiliary feeding plate 10 abuts against the stirring teeth 7.
[0033] When the stirring teeth 7 rotate to contact the back of the auxiliary material feeding plate 10, the auxiliary material feeding plate 10 is rotatably connected to the inner wall of the mixing tank 1 via the bearing 11. The pushing force of the stirring teeth 7 causes the auxiliary material feeding plate 10 to oscillate back and forth around the bearing 11. At this time, the return spring 12 fixed to the front of the auxiliary material feeding plate 10 is compressed and stores energy. When the stirring teeth 7 disengage, the return spring 12 releases its elastic potential energy, pushing the auxiliary material feeding plate 10 to return to its original position, thus forming a periodic feeding of materials near the tank wall, preventing materials from adhering to the tank wall or creating mixing dead zones.
[0034] Example 2
[0035] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a return spring 12 is fixedly connected to the front side of the auxiliary feeding plate 10.
[0036] A feed hopper 2 is fixedly connected to the top of the mixing tank 1.
[0037] A support frame 3 is fixedly connected to the bottom of the mixing tank 1.
[0038] A discharge pipe 4 is fixedly connected to the bottom of the mixing tank 1, and a control valve 13 is installed on the outer wall of the discharge pipe 4.
[0039] The working principle of this agricultural fertilizer mixing device will be explained in detail below.
[0040] like Figure 1-4 As shown, the working process of this agricultural fertilizer mixing device is based on the coordinated linkage of various components, and the specific principle is as follows:
[0041] (a) Material input and initial distribution
[0042] Multiple agricultural fertilizers to be mixed are fed into the mixing tank 1 through the feed hopper 2, which is fixedly connected to the top. The fertilizers initially accumulate at the bottom of the mixing tank 1, and the support frame 3 ensures stable support of the device, providing basic support conditions for the subsequent mixing process.
[0043] (II) Operation of the main mixing system
[0044] When the drive motor 5 is powered on, it starts, and its output end drives the rotating rod 6 to rotate clockwise or counterclockwise. The stirring teeth 7 fixed on the outer wall of the rotating rod 6 rotate synchronously with the rod body, forming an initial stirring and shearing force on the fertilizer in the tank, breaking up large pieces of material and initially mixing them.
[0045] (III) Synergistic effect of auxiliary material feeding components
[0046] When the stirring teeth 7 rotate to contact the back of the auxiliary material feeding plate 10, the auxiliary material feeding plate 10 is rotatably connected to the inner wall of the mixing tank 1 via the bearing 11. The pushing force of the stirring teeth 7 causes the auxiliary material feeding plate 10 to oscillate back and forth around the bearing 11. At this time, the return spring 12 fixed to the front of the auxiliary material feeding plate 10 is compressed and stores energy. When the stirring teeth 7 disengage, the return spring 12 releases its elastic potential energy, pushing the auxiliary material feeding plate 10 to return to its original position, thus forming a periodic feeding of materials near the tank wall, preventing materials from adhering to the tank wall or creating mixing dead zones.
[0047] (iv) Bottom material circulation mechanism
[0048] The rotating rod 6 and the arc-shaped shovel plate 8 near the bottom outer wall maintain contact and slide against the bottom surface of the inner wall of the mixing tank 1 as the rod rotates. The inclined thrust generated by the arc structure shovels up and throws the fertilizer deposited at the bottom, forming an upward and downward convection with the material driven by the central stirring teeth 7, thus solving the problem of material accumulation at the bottom of traditional mixing devices.
[0049] (v) Material output control
[0050] After mixing is complete, the control valve 13 on the outer wall of the discharge pipe 4 is opened, and the uniformly mixed fertilizer is discharged through the discharge pipe 4 under the action of gravity, thus completing the entire mixing process.
