[0018] In this embodiment, the support frame 1 serves as the basic support structure for the entire seed mixing machine, ensuring the stability of the equipment during operation.

[0019] like Figure 1 As shown, a roller frame 2 is rotatably mounted on the support frame 1. A support component 3 is provided between one end of the roller frame 2 and the support frame 1. The support component 3 is used to support and limit the roller frame 2. A seed mixing roller 4 is rotatably mounted on the roller frame 2.

[0020] In this embodiment, the seed mixing roller 4 is used to load seeds and pesticides, and to mix the seeds and pesticides therein.

[0021] In this embodiment, the seed mixing roller 4 is made of corrosion-resistant 304 stainless steel, which facilitates the long-term use of the seed mixing machine.

[0022] Preferably, the seed mixing roller 4 has an opening 5 at one end near the support component 3 and is hinged to a roller cover plate 6. A limiting component 7 is provided on the seed mixing roller 4 to limit the roller cover plate 6.

[0023] Preferably, the two ends of the seed mixing roller 4 are fixedly installed with roller shafts 8, and the roller shafts 8 are rotatably installed on the roller frame 2.

[0024] In this embodiment, the roller shaft 8 extends along the axial direction of the seed mixing roller 4 and penetrates the interior of the seed mixing roller 4, so that both ends of the roller shaft 8 extend out of the two ends of the seed mixing roller 4 respectively, and the ends of the roller shaft 8 extending out of the seed mixing roller 4 are rotatably mounted on the roller frame 2.

[0025] In this embodiment, the setting of the roller shaft 8 ensures the stable operation of the seed mixing roller 4 during rotation.

[0026] Preferably, a crank handle 9 is fixed to one end of the roller shaft 8 that extends out of the roller frame 2.

[0027] In this embodiment, the crank handle 9 is provided so that the operator can manually rotate it to drive the seed mixing roller 4 to rotate in order to complete the seed mixing work.

[0028] Preferably, the middle part of the roller frame 2 is rotatably mounted on the support frame 1 via a flip shaft 10, and the axis of the flip shaft 10 is perpendicular to the axis of the roller shaft 8.

[0029] In this embodiment, the roller frame 2 adopts a square frame, and the seed mixing roller 4 is set inside the roller frame 2.

[0030] In this embodiment, the function of the roller frame 2 is to fix the seed mixing roller 4 and to realize the flipping function of the seed mixing roller 4 through the flipping shaft 10.

[0031] In this embodiment, the roller frame 2 is made of metal.

[0032] Furthermore, the tilting shaft 10 is rotatably mounted on the support frame 1 via a high-strength bearing, ensuring the smooth rotation of the roller frame 2.

[0033] Preferably, the support assembly 3 includes a support rod 301, the lower end of which is hinged to the support frame 1, and a fixing cylinder 302 is fixed to the upper end of the support rod 301. The roller frame 2 is provided with a through hole 201 coaxially arranged with the fixing cylinder 302, and a pin 303 passes through both the through hole 201 and the interior of the fixing cylinder 302.

[0034] In this embodiment, the support component 3 is provided to support the roller frame 2 during the seed mixing process, so as to ensure that the seed mixing roller 4 rolls parallel, thereby achieving the effect of fully mixing the seeds and the agent.

[0035] Preferably, the limiting component 7 includes a fixing seat 701 fixed to the outer wall of the seed mixing drum 4. A slide rod 702 is slidably installed on the fixing seat 701 along the axial direction of the seed mixing drum 4. One end of the slide rod 702 is provided with a locking part 703 for locking the drum cover plate 6. The other end of the slide rod 702 and the fixing seat 701 are connected together by a locking spring 704.

[0036] In this embodiment, during the mixing of seeds and agents, the drum cover plate 6 can be opened to observe the mixing state of the materials inside the seed mixing drum 4.

[0037] Furthermore, operators can adjust the rotation speed and force according to the mixing state of the seeds and the agent to achieve the best mixing effect.

[0038] In addition, operators can adjust the mixing time according to the amount of materials to be mixed and the mixing requirements, which is generally 5-10 minutes.

[0039] The process for mixing seeds and pesticides using this invention is as follows: First, pull out the pin 303 of the support component 3, and after laying down the support rod 301, rotate the seed mixing roller 4 to a vertical position and set the roller cover plate 6 facing upward. The second step is to pull the locking part 703 away from the roller cover 6 to unlock the roller cover 6, and then the roller cover 6 can be flipped open. The third step is for the operator to add the prepared seeds and pesticides into the seed mixing drum 4 in a predetermined ratio through the opening at the top of the seed mixing drum 4 (the total amount of seeds and pesticides should not exceed the maximum capacity of the seed mixing drum 4 to prevent material leakage during the mixing process and avoid affecting the mixing effect). Fourth step, close the roller cover plate 6 and rotate the slide rod 702 so that the locking part 703 is aligned with the outer wall of the roller cover plate 6. Under the elastic force of the locking spring 704, the locking part 703 is pressed against the outer wall of the roller cover plate 6. Fifth step, rotate the seed mixing roller 4 to a horizontal position, and use the pin 303 again to fix the roller frame 2 in a horizontal state; Step 6: Hold the crank handle 9 and manually rotate the crank handle 9 to drive the seed mixing drum 4 to rotate (rotate slowly at first and gradually increase the speed to adapt to the operating state of the equipment). Step 7: After completing the seed mixing work, the operator stops cranking the handle 9, stops the seed mixing roller 4 from rotating, and lowers the support rod 301 again. Step 8: The entire roller frame 2 and the seed mixing roller 4 are flipped together by the flipping shaft 10, so that the seed mixing roller 4 is in an inclined or inverted state. Step 9: Open the roller cover 6 again to allow the mixed seed mixture to flow out naturally; The tenth step is to collect the mixed materials for subsequent sowing or other treatments.

[0040] In summary, the seed mixer has a very simple structure and a much lower manufacturing cost compared to traditional electric seed mixers. Moreover, it is easy for operators to disassemble and assemble, making it more convenient to carry.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
