DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] In order to solve the technical problem that the height of a stirring piece cannot be changed, resulting in a poor stirring effect, the utility model provides a stirring device, which can achieve the height change of the stirring piece and improve the stirring effect.

[0028] It should be noted that the stirring device described in the present invention is used for but not limited to compound fertilizers, etc. For the convenience of explanation, in the present invention, only an example of a stirring device applied to compound fertilizers is used for explanation. The principle of a stirring device applied to other types of equipment is substantially the same as that applied to compound fertilizers, and will not be described in detail here.

[0029] See also Figure 1-Figure 4 A stirring device includes a mixing kettle 1, a rotating mechanism 2 and a stirring mechanism 3. The rotating mechanism 2 is transmission-connected to the bottom of the mixing kettle 1. The stirring mechanism 3 includes a stirring rod 31, a driving wheel 32 and a first driving member 33. The driving wheel 32 is located at one side of the mixing kettle 1. One end of the stirring rod 31 is fixedly connected to one side of the driving wheel 32, and the other end of the stirring rod 31 extends into the mixing kettle 1. The first driving member 33 is used to drive the driving wheel 32 to rotate and make the other end of the stirring rod 31 perform a circular motion in the vertical direction.

[0030] In this embodiment, one end of the stirring rod 31 is fixedly connected to one side of the driving wheel 32, so that when the first driving member 33 drives the driving wheel 32 to rotate, it will drive the other end of the stirring rod 31 to make a circular motion in the mixing kettle 1, and then cooperate with the rotating mechanism 2 to drive the mixing kettle 1 to rotate, so that all fertilizers in the mixing kettle 1 can be stirred by the end of the stirring rod 31 when passing through the stirring rod 31. Therefore, compared with the traditional stirring paddle with a fixed height, in this solution, the stirring rod 31 makes a vertical circular motion, so that fertilizers at different heights can be stirred, the stirring is more uniform, and the stirring effect is effectively improved.

[0031] First, various fertilizers required for compound fertilizer are poured into the mixing kettle 1; then, the rotating mechanism 2 is started to drive the mixing kettle 1 to rotate, so that the fertilizers in every place in the mixing kettle 1 can pass through the stirring rod 31; finally, the first driving member 33 is started, and the driving wheel 32 is rotated, so that the stirring rod 31 extends into the end of the mixing kettle 1 to make a longitudinal circular motion, thereby continuously stirring the fertilizers in the mixing kettle 1.

[0032] Furthermore, the first driving member 33 adopts a servo motor, which can effectively control the stirring speed of the stirring rod 31 .

[0033] In one embodiment, see Figure 1 The bottom of the mixing kettle 1 is rotatably connected to a base 211 .

[0034] In this embodiment, a through hole is opened on the base 211, and bolts are passed through the through hole to be fixedly connected to the ground. A rotating shaft is provided between the mixing kettle 1 and the base 211. The rotating shaft leaves a certain gap between the mixing kettle 1 and the base 211, so that the mixing kettle 1 rotates more smoothly and avoids friction between the mixing kettle 1 and the base 211.

[0035] In one embodiment, see Figure 1 The rotating mechanism 2 includes a worm wheel 21, a worm 22 and a second driving member 23. The worm wheel 21 is fixedly sleeved on the outer wall of the mixing kettle 1, the worm 22 is meshed with the worm wheel 21, and the second driving member 23 is used to drive the worm 22 to rotate.

[0036] In this embodiment, the second driving member 23 is a servo motor, which can effectively control the rotation speed of the worm gear 21 .

[0037] Furthermore, the bottom plate of the worm gear 21 may be provided with a flipping mechanism, so that the rotating mechanism 2 and the mixing kettle 1 can be flipped together, so as to facilitate the mixing kettle 1 to discharge the mixed compound fertilizer.

[0038] In one embodiment, see Figure 2 The stirring rod 31 has a U-shaped structure, one end of the stirring rod 31 is fixedly connected to the driving wheel 32, and the other end of the stirring rod 31 extends into the mixing kettle 1.

[0039] In this embodiment, the U-shaped stirring rod 31 can effectively match the shape of the side wall of the mixing kettle 1, thereby making greater use of the space.

[0040] In one embodiment, see Figure 2 A gripper 311 is provided at one end of the stirring rod 31 extending into the mixing kettle 1 .

[0041] In this embodiment, the gripper 311 is used to stir more fertilizer when the end of the stirring rod 31 makes a longitudinal circular motion.

[0042] In one embodiment, see Figure 2 The stirring mechanism 3 also includes a pair of transmission wheels 34, which are respectively located at the upper and lower ends of the driving wheel 32 and are both meshed with the driving wheel 32. The end of the stirring rod 31 away from the mixing kettle 1 is fixedly connected to one side of the two transmission wheels 34.

[0043] In this embodiment, the driving wheel 32 is located between the two transmission wheels 34, which can enable the transmission wheels 34 to rotate in the same direction. The stirring rod 31 is fixedly connected to the edges of the two transmission wheels 34. Compared with being connected to only one driving wheel 32, the two transmission wheels 34 have a better stabilizing effect, making the stirring rod 31 more stable during operation.

[0044] It should be noted that the two transmission wheels 34 have the same structure and are respectively located at the upper and lower ends of the driving wheel 32. When the driving wheel 32 rotates, the two transmission wheels 34 can run synchronously, thereby facilitating a more stable operation of the stirring rod 31.

[0045] In one embodiment, see Figure 3 Isolation brackets 35 are provided on both sides of the driving wheel 32 .

[0046] In this embodiment, the function of the isolation bracket 35 is to enhance the protection effect for the driving wheel 32, the transmission wheel 34 and the stirring rod 31 to prevent external factors from affecting their normal operation.

[0047] In one embodiment, see Figure 2 A protrusion 312 is provided at one end of the stirring rod 31 away from the driving wheel 34 , and an annular slideway 351 is provided on one side of the isolation bracket 35 facing the stirring rod 31 . The protrusion 312 is arranged in the annular slideway 351 and is slidably connected to the annular slideway 351 .

[0048] In this embodiment, the protrusion 312 is slidably embedded in the annular slideway 351, so that both sides of the stirring rod 31 can be supported, which effectively improves the stability of the stirring rod 31 during operation.

[0049] In one embodiment, see Figure 3-Figure 4 A rotating rod 352 is provided at the bottom of the isolation bracket 35 , and a cylinder 36 is provided below the isolation bracket 35 . The rotating rod 352 is rotatably sleeved in the cylinder 36 .

[0050] In this embodiment, the rotating rod 352 and the cylinder 36 are provided to enable the isolation bracket 35 to realize the rotation function. When the staff needs to pick up the compound fertilizer after stirring, in order to avoid the interference of the stirring rod 31, the staff needs to rotate the isolation bracket 35 so that the stirring rod 31 extends out of the mixing kettle 1 and moves away.

[0051] Furthermore, the bottom of the cylinder 36 is fixedly connected to a bottom plate, and a plurality of through holes are formed on the bottom plate. The cylinder 36 is fixedly connected to the ground by bolts passing through the through holes.

[0052] In one embodiment, see Figure 1 and Figure 4 A threaded hole 361 is formed on the side wall of the cylinder 36 , and a screw rod 37 is threadedly sleeved in the threaded hole 361 . The screw rod 37 is threadedly connected to the threaded hole 361 and is used to abut against the rotating rod 352 .

[0053] In this embodiment, the threaded hole 361 is threadedly connected to the screw rod 37, and a handle is provided at the end of the screw rod 37 away from the threaded hole 361, so that the staff can manually twist the screw rod 37 and control the force of the screw rod 37 abutting against the rotating rod 352 by rotating the screw 37. When the force of the screw 37 abutting against the rotating rod 352 is large, the rotating rod 352 cannot rotate autonomously, thereby effectively preventing the isolation bracket 35 from rotating autonomously and affecting the work.

[0054] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

[0055] First, various fertilizers required for the compound fertilizer are poured into the mixing kettle 1; then, the second driving member 23 is started, so that the worm 22 drives the worm wheel 21 to rotate, thereby realizing the self-rotation of the mixing kettle 1, so that the fertilizers in each place in the mixing kettle 1 can pass through the stirring rod 31; then, the first driving member 33 is started, the driving wheel 32 rotates, and drives the two transmission wheels 34 to run synchronously, so that the stirring rod 31 is extended into the gripper 311 of the mixing kettle 1 to make a vertical circular motion, thereby continuously stirring the fertilizers in the mixing kettle 1, and finally, after the fertilizers are evenly stirred, the contact of the screw 37 with the rotating rod 352 is loosened, and the isolation bracket 35 is rotated, so that the isolation bracket 35 drives the stirring rod 31 to move out and away from the mixing kettle 1, so as to facilitate the unloading of the mixing kettle 1. Compared with the traditional stirring paddle with a fixed height, the utility model uses the stirring rod 31 to make a vertical circular motion in this scheme, so that fertilizers at different heights can be stirred, the stirring is more uniform, and the stirring effect is effectively improved.

[0056] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
