[0011] Beneficial effects This invention provides a liquid fertilizer mixing device for water-saving irrigation and fertilization in farmland.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides two technical solutions: Figures 1-6 The first embodiment is shown: a liquid fertilizer mixing device for water-saving irrigation and fertilization of farmland water conservancy, including a mixing cylinder 1, a cylinder cover 2 fixedly installed at the top of the mixing cylinder 1, and a stirring component 3 and a mixing component 4 respectively provided at the top of the cylinder cover 2. The stirring assembly 3 includes a rotating sleeve 31, a sliding column 32 slidably disposed on the inner wall of the rotating sleeve 31, a stirring rod 36 fixedly installed at the bottom end of the sliding column 32, a set of stirring plates 37 fixedly installed on the outer wall of the stirring rod 36, a pressing plate 33 rotatably installed at the top end of the sliding column 32, and a cam 39 disposed at the top end of the pressing plate 33. When the cam 39 rotates, it can press the pressing plate 33, thereby causing the sliding column 32 and the stirring rod 36 to move vertically. The mixing assembly 4 includes an arc-shaped cylinder 41, and a set of rotating cylinders 42 are rotatably connected to the bottom end of the arc-shaped cylinder 41. A set of leakage channels is opened through the bottom end of the rotating cylinders 42, through which liquid fertilizer can flow out.

[0017] Two slide rods 34 slide through the top of the extrusion plate 33. The bottom ends of the two slide rods 34 are fixedly installed on the top of the cylinder cover 2. Springs 35 are sleeved on the outer wall of the slide rods 34. One end of the two springs 35 is fixedly connected to the cylinder cover 2, and the other end of the two springs 35 is fixedly connected to the extrusion plate 33. The springs 35 can reset the extrusion plate 33 after it loses its extrusion.

[0018] A vertical plate 38 is fixedly installed on the top of the cylinder cover 2. A rotating shaft is rotatably installed on the outer wall of the vertical plate 38. One end of the outer wall of the rotating shaft is fixedly connected to the cam 39, and a worm gear 310 is fixedly installed on the other end of the outer wall of the rotating shaft.

[0019] Figures 1-6 The second embodiment is shown. The main difference from the first embodiment is that a mounting bracket 311 is fixedly installed on one side of the outer wall of the vertical plate 38. A worm gear 312 is rotatably installed on the inner wall of the mounting bracket 311. The worm gear 312 is meshed with a worm wheel 310. The worm wheel 310 and the worm gear 312 have self-locking properties. One end of the outer wall of the worm gear 312 passes through the outer wall of the mounting bracket 311 and is fixedly installed with a rocker arm 313. The rocker arm 313 can drive the worm gear 312 to rotate, thereby controlling the rotation of the worm wheel 310. The worm wheel 310 can then drive the cam 39 to rotate.

[0020] Two splines are fixedly installed on the outer wall of the sliding column 32. When the rotating sleeve 31 rotates, it can drive the sliding column 32 to rotate. At the same time, the sliding column 32 can slide up and down inside the rotating sleeve 31. The outer wall of a set of rotating cylinders 42 is fixedly fitted with an external gear ring 43. The outer wall of the rotating sleeve 31 is fixedly installed with a gear disk 44. The gear disk 44 is meshed with a set of external gear rings 43. When the external gear ring 43 rotates, it can drive a set of gear disks 44 and rotating cylinders 42 to rotate simultaneously. When the rotating cylinder 42 rotates, it can evenly distribute the liquid fertilizer inside the mixing cylinder 1 under the action of centrifugal force.

[0021] A motor 45 is fixedly installed at the top of the cylinder cover 2. The output end of the motor 45 passes through the bottom end of the cylinder cover 2 and a rotating gear 46 is fixedly installed thereon. The rotating gear 46 meshes with the gear disk 44. The outer wall of the mixing cylinder 1 is provided with an inlet pipe and an outlet pipe. Irrigation water can enter the mixing cylinder 1 through the inlet pipe, and the mixed liquid can be discharged through the outlet pipe.

[0022] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0023] During operation, liquid fertilizer and irrigation water are added to the mixing drum 1 through the arc-shaped cylinder 41 at the top of the cover 2 and the inlet pipe, respectively. The motor 45 is started, and its output drives the rotating gear 46 to rotate. Because the rotating gear 46 meshes with the gear disk 44, the gear disk 44 rotates synchronously with the rotating gear 46, thereby driving the rotating sleeve 31, which is fixedly connected to the gear disk 44, to rotate. The rotating sleeve 31, through a spline engagement between its inner wall and the outer wall of the sliding column 32, drives the sliding column 32 to rotate synchronously as it rotates. The stirring rod 36 at the bottom of column 32 and a set of stirring plates 37 on the outer wall of the stirring rod 36 rotate accordingly. At the same time, since the gear disk 44 on the rotating sleeve 31 meshes with the outer gear ring 43 on the outer wall of the rotating cylinder 42, the rotating cylinder 42 rotates synchronously with the gear disk 44. The liquid introduced into the arc-shaped cylinder 41 is guided through the arc-shaped cylinder 41 to a set of rotating cylinders 42 at the bottom. During the rotation, the liquid leakage groove at the bottom of the rotating cylinder 42 evenly sprays the liquid into the mixing cylinder 1. In addition, rotating the rocker arm 313 drives the worm gear 312. Rotating within the mounting bracket 311, the worm gear 312 meshes with the worm wheel 310, driving the worm wheel 310 and the rotating shaft fixed thereto to rotate. The cam 39 at the other end of the rotating shaft rotates along with it. When the cam 39 rotates, it periodically squeezes the squeezing plate 33. The squeezing plate 33 slides down along the slide rod 34 and compresses the spring 35. When the protruding part of the cam 39 leaves the squeezing plate 33, the spring 35 resets and pushes the squeezing plate 33 to slide upward. Through the reciprocating motion of the squeezing plate 33, the sliding column 32 slides up and down along the inner wall of the rotating sleeve 31, so that the stirring rod 36 and the stirring plate 37 complete the lifting and lowering motion while rotating, and perform three-dimensional stirring of the liquid dispersed by the mixing component 4. Finally, the uniform mixture is discharged through the liquid outlet pipe on the outer wall of the mixing cylinder 1 and enters the irrigation system to complete the fertilization operation. The uniform water and fertilizer mixture can accurately meet the crop's nutrient requirements, without the need to dilute the local high-concentration fertilizer by increasing the irrigation water volume, and without the need for additional water and fertilizer due to insufficient nutrients in some areas caused by uneven mixing, thus reducing the water consumption of ineffective irrigation.
