[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] Please refer to Figures 1 to 4 A rice seed mixing device for agricultural planting, comprising a base 1, the two ends of the base 1 are respectively connected with a support assembly and a lifting assembly, the side away from the base 1 of the support assembly and the lifting assembly is connected with a fixed collar 2, a stirring barrel 3 is connected in the two fixed collars 2, the outer wall of the two ends of the stirring barrel 3 is fixedly connected with a limiting ring 4, the inner wall of the two fixed collars 2 is provided with a limiting groove 201, the two limiting rings 4 are respectively and slidingly connected with the two limiting grooves 201, a driving assembly is connected between the two fixed collars 2, the driving assembly is connected with the stirring barrel 3, and a material port 301 is provided at the end of the stirring barrel 3 away from the lifting assembly.

[0024] As Figures 1 to 4As shown, the rice seed dressing device for agricultural planting in this utility model is structurally similar to existing rice seed dressing devices for agricultural planting. The main improvement of this utility model lies in reducing the damage to seeds caused by the seed dressing operation and improving the seed dressing effect. Figures 1 to 4 As shown, in the rice seed mixing device for agricultural planting of this utility model, the rice seeds to be mixed, along with pesticides, fertilizers, etc., are added into the mixing tank 3 through the feed inlet 301. Then, the driving component drives the mixing tank 3 to rotate laterally inside the two fixed sleeve rings 2 through the limiting rings 4 at both ends. The friction of the inner wall of the mixing tank 3 drives the internal materials to continuously tumble and mix. The mixing is carried out by the natural falling of the materials, avoiding the squeezing and damage to the rice seeds caused by the traditional mixing rod, and improving the stability of the rice seeds after mixing. After the mixing operation is completed, one end of the mixing tank 3 can be lifted upward by the lifting component, thereby tilting the mixing tank 3 so that the rice seeds that have been mixed are poured out from the feed inlet 301, completing the entire mixing operation.

[0025] like Figures 1 to 3 As shown, the support assembly includes two symmetrically arranged support rods 6, both of which are fixedly connected to the base 1. The outer walls of the fixing collar 2 near the feed inlet 301 are rotatably connected to the ends of the two support rods 6 away from the base 1 via rotating shafts. One end of the mixing tank 3 can be fixed to the base 1 by the two support rods 6, and during the lifting operation, it can be rotated on the two support rods 6 via the rotating shafts.

[0026] like Figures 1 to 3 As shown, the lifting assembly includes two symmetrically arranged lifting devices 7. Each lifting device 7 has a fixedly connected tilting block 8 at its telescopic end. U-shaped support blocks 9 are fixedly connected to the outer walls of the fixed collar 2 on both sides of the end furthest from the feed inlet 301. The two tilting blocks 8 are rotatably connected to the inner walls of the two U-shaped support blocks 9 via rotating shafts. Support plates 10 are rotatably connected to both sides of the end of each lifting device 7 furthest from its telescopic end via rotating shafts. All four support plates 10 are fixedly connected to the base 1. The two lifting devices 7 lift synchronously, raising the end of the mixing tank 3 to a certain height, tilting the mixing tank 3, and pouring out the rice seeds inside. During the lifting process, the upper and lower ends of the lifting devices 7 rotate at a certain angle along with the tilted mixing tank 3 via the tilting blocks 8 and the support plates 10, ensuring stable lifting operation. The lifting devices 7 can be hydraulic cylinders or pneumatic cylinders, etc., capable of stable upward and downward movement. The lifting devices 7 on both sides need to maintain synchronous movement.

[0027] like Figures 1 to 3As shown, the drive assembly includes a drive motor 11, a drive gear 12, an outer tooth ring 13 and two symmetrically arranged support frames 14, both ends of the two support frames 14 are fixedly connected with the two fixed collar 2 respectively, the shell of the drive motor 11 is fixedly connected with the two support frames 14 through the mounting seat, the drive gear 12 is fixedly connected with the output shaft of the drive motor 11, the outer tooth ring 13 is sleeved with the outer wall of the stirring barrel 3 and is fixedly connected with the stirring barrel 3, and the drive gear 12 is engaged with the outer tooth ring 13. The drive motor 11 is fixed between the two fixed collars 2 through the two support frames 14, the drive motor 11 is started, the drive gear 12 is driven to rotate, and then the outer tooth ring 13 engaged with the drive gear 12 is driven to rotate, so that the stirring barrel 3 can be driven to tumble in the two fixed collars 2.

[0028] As shown in Figures 1 to 4 , the outer tooth ring 13 is located at the middle position of the stirring barrel 3. The outer tooth ring 13 is arranged at the middle position of the stirring barrel 3, so that when the stirring barrel 3 tumbles, the force on both ends is more uniform, and the tumbling and mixing movement is more stable.

[0029] As shown in Figures 1 to 3 , the material port 301 is located at the edge of one end of the stirring barrel 3, and the material port 301 is connected with the door 5 away from the stirring barrel 3. During the mixing operation, the door 5 can be used to close the material port 301 to prevent the internal material from falling during the mixing operation. After the mixing operation is completed, the other end of the stirring barrel 3 is lifted by the lifting assembly, then the stirring barrel 3 is manually rotated, the position of the material port 301 is adjusted to the bottom, and then the door 5 is opened. At this time, the internal material of the stirring barrel 3 can fall by gravity and fall from the material port 301 at the bottom edge of the end, so that the mixed rice seeds can be taken out smoothly, and the material port 301 at the bottom edge can make the internal material of the stirring barrel 3 completely discharged, avoiding the accumulation of the internal material in the stirring barrel 3. Among them, the drive motor 11 needs to be a non-locking motor, so that the stirring barrel 3 can be manually rotated smoothly.

[0030] As shown in Figures 1 to 3 , one side of the door 5 is hinged with the stirring barrel 3 through a plurality of hinges, and the other side is connected with the stirring barrel 3 through a fastener. The hinges facilitate the door 5 to be turned and opened from the side of the material port 301, and the fastener facilitates the door 5 to be fixed and closed with the stirring barrel 3 to prevent the internal material from falling during the mixing operation.

[0031] As shown in Figures 1 to 3As shown, the fastener comprises a fixing ring 15 and a fastening bolt 16, the fixing ring 15 is fixedly connected with the end of the door 5 away from the hinge, and the threaded rod of the fastening bolt 16 penetrates through the fixing ring 15 and is threadedly connected with the preset threaded hole of the stirring barrel 3. When closing the door 5, the fastening bolt 16 is screwed through the fixing ring 15 and the threaded hole preset at the end of the stirring barrel 3, so as to fix the door 5 outside the material port 301 of the stirring barrel 3, complete the operation of closing the material port 301 of the door 5, and the threaded fastening mode is not easy to loosen during the rolling of the stirring barrel 3, and the stability is good.

[0032] As shown in the drawings, Figure 4 As shown, the inner wall of the stirring barrel 3 is fixedly connected with a plurality of circumferentially distributed stirring ribs 17. When the stirring barrel 3 is rolling, the stirring ribs 17 can roll the seed material to a higher position and then drop down, so as to improve the mixing of the seed material and improve the seed mixing effect.

[0033] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model.
