[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0033] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0034] like Figures 1-5 As shown, a seed mixing device in this embodiment includes a frame 100 and a mixing tank 110 disposed on the frame 100. The mixing tank 110 is provided with a mixing component, which includes a rotatable shaft 200 and an auger blade 201 disposed outside the shaft 200. The auger blade 201 is spirally and concentrically fixed to the outer side wall of the shaft 200. The frame 100 is provided with a liquid supply component for supplying liquid to the mixing tank 110. In actual use, the liquid supply component is used to input emulsion agent into the mixing tank 110.

[0035] The rotating shaft 200 has a cavity 301 with an open top. The outer wall of the rotating shaft 200 is provided with a liquid outlet 202 that communicates with the cavity 301. The liquid supply assembly includes a medicine storage tank 120. The bottom of the medicine storage tank 120 is provided with a liquid supply pipe 130 through a water pump 210. One end of the liquid supply pipe 130 extends into the cavity 301. The rotating shaft 200 is provided with a fixing assembly for fixing the liquid supply pipe 130.

[0036] In actual use, the seeds are poured into the mixing tank 110, and the rotating shaft 200 drives the auger blades 201 to rotate, continuously turning the seeds at the bottom of the mixing tank 110 to the upper part of the mixing tank 110, thereby mixing them with the medicine added to the mixing tank 110.

[0037] Specifically, in order to achieve the rotation of the rotating shaft 200, in this embodiment, the lower end of the rotating shaft 200 extends through the bottom of the mixing tank 110. The extended end of the rotating shaft 200 is provided with a first rotating wheel, and a motor 150 is provided on the frame 100. The output end of the motor 150 is provided with a second rotating wheel, and a belt 151 is sleeved between the first rotating wheel and the second rotating wheel. Through the above structure, the motor 150 drives the rotating shaft 200 to rotate, thereby realizing the mixing component to stir and mix the seeds and agents in the mixing tank 110.

[0038] In this embodiment, a discharge hopper 111 is provided at the bottom of the mixing tank 110. A plug plate for sealing is inserted into the discharge hopper 111. By inserting and removing the plug plate, the seeds after mixing in the mixing tank 110 can be discharged more effectively.

[0039] In actual use, the storage tank 120 is used to store emulsion medicine. The water pump 210 is used to pump the emulsion medicine in the storage tank 120 into the cavity 301 through the liquid supply pipe 130. The liquid outlet 202 is distributed along the axis of the rotating shaft 200. The liquid outlet 202 allows the medicine in the cavity 301 to be discharged into the mixing tank 110 in a more dispersed manner. As the rotating shaft 200 rotates, the seeds and medicine can be mixed more evenly.

[0040] Specifically, the liquid supply pipe 130 is made of soft water pipe. In order to prevent the liquid supply pipe 130 from being too heavy and causing it to detach from the cavity 301, thus affecting the addition of the liquid to the mixing tank 110 through the cavity 301 and the outlet hole 202, the liquid supply pipe 130 can be fixed by setting a fixing component.

[0041] In this embodiment, a support 140 is provided inside the mixing tank 110. The two ends of the support 140 are bent to form mounting parts. The mounting parts are fixedly installed inside the mixing tank 110 by screws. The upper end of the rotating shaft 200 is installed on the lower side wall of the support 140 through a bearing seat. Thus, the rotating shaft 200 is installed in a relatively stable rotational manner inside the mixing tank 110.

[0042] The fixing assembly includes a clamping member fixedly mounted on the bracket 140 and a rotating member rotatably mounted on the clamping member. The liquid supply pipe 130 extends through the clamping member, the rotating member, and the bracket 140 into the cavity 301. The rotating member is rotatably connected to the clamping member so that the clamping member clamps the liquid supply pipe 130.

[0043] In this embodiment, the above-described structure can better achieve the fixed installation of the liquid supply pipe 130 on the bracket 140, and can always keep the liquid supply pipe 130 inside the cavity 301.

[0044] Combination Figure 4 As shown, in this embodiment, the clamping member includes a clamping cylinder portion 410 and a deformation portion 420 provided on the clamping cylinder portion 410. The outer side wall of the deformation portion 420 is provided with an outer truncated circular surface along its circumference.

[0045] The rotating component includes a rotating cylinder portion 430 and an extrusion portion 440. The rotating cylinder portion 430 is threadedly connected to the clamping cylinder portion 410. The extrusion portion 440 has an inner cylindrical platform that mates with the outer cylindrical platform.

[0046] The liquid supply pipe 130 is externally fixed with a fixing cylinder 450 that cooperates with the clamping component.

[0047] In practical use, the deformable part 420 is provided with a gap groove along its circumference to maintain the deformability of the deformable part 420. The outer side wall of the clamping cylinder part 410 is provided with an external thread, and the inner side wall of the rotating cylinder part 430 is provided with an internal thread, thereby realizing the threaded connection between the two. When the rotating cylinder part 430 is threadedly connected to the clamping cylinder part 410, the squeezing part 440 squeezes the deformable part 420, making it clamp the liquid supply pipe 130, thereby fixing the liquid supply pipe 130. When the thread of the rotating cylinder part 430 moves away from the clamping cylinder part 410, the squeezing part 440 can move away from the deformable part 420, thereby releasing the fixation of the liquid supply pipe 130, so as to facilitate the disassembly and cleaning of the liquid supply assembly.

[0048] The liquid supply pipe 130 passes through the fixed cylinder 450 and is fixed inside the fixed cylinder 450 so that the deformable part 420 can hug the fixed cylinder 450 and thus fix the liquid supply pipe 130.

[0049] The outer wall of the fixed cylinder 450 is provided with a retaining ring 451 that overlaps the rotating part, which preferably limits the distance of the fixed cylinder 450 inserted into the clamping part, so as to ensure that the deformable part 420 clamps the fixed cylinder 450 and fixes the liquid supply pipe 130.

[0050] Specifically, in order to facilitate the operator to pick up and put down the fixed cylinder 450 at the clamping part and the rotating part, the fixed cylinder 450 located above the retaining ring 451 forms a gripping part.

[0051] In this embodiment, a mounting column 160 is provided on one side of the frame 100, and a detachable mounting plate 170 is provided at the upper end of the mounting column 160. The medicine storage tank 120 is provided on the mounting plate 170, and a stirring assembly is provided inside the medicine storage tank 120.

[0052] Specifically, in combination Figure 6 As shown, the mounting column 160 is made of channel steel, and the mounting plate 170 has fixing plates 220 at both ends. The fixing plates 220 extend into the corresponding channel steel so that the mounting plate 170 overlaps to the top of the mounting column 160. The fixing plates 220 have threaded holes, and the mounting column 160 has bolts with threads that extend into the corresponding threaded holes. This allows for better assembly and disassembly of the mounting plate 170, which facilitates the disassembly of the liquid supply assembly.

[0053] In this embodiment, the medicine storage tank 120 has an opening at the upper end, and a plug 121 is threaded onto the opening end of the medicine storage tank 120; the stirring assembly includes a stirring shaft 510 disposed on the plug 121, the stirring shaft 510 is rotatably disposed, and a stirring rod 511 is disposed on the stirring shaft 510.

[0054] In this embodiment, a servo motor 122 for driving the stirring shaft 510 to rotate is provided on the plug 121. The servo motor 122 can better drive the stirring shaft 510 to drive the stirring rod 511 to rotate.

[0055] In actual use, by unscrewing the plug 121 by thread, the stirring component is driven to extend out of the storage tank 120. At this time, the medicine is added into the storage tank 120. Then, the plug 121 is screwed on to install it on the storage tank 120. The water pump 210 can be used to add the medicine into the cavity 301.

[0056] The servo motor 122 can effectively drive the stirring shaft 510 to rotate the stirring rod 511, which can stir the medicine in the medicine storage tank 120, making the medicine more uniform so that it can be added into the stirring bucket 110.

[0057] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
