[0031] In an embodiment of the present utility model, please refer to Figures 1 to 3, the adjusting structure 4 includes two support plates 401. The two support plates 401 are fixedly connected to the bracket 1. On the sides of the two support plates 401 close to each other, a rotating shaft 402 is rotatably connected. On one side of one of the support plates 401, a motor 403 is fixedly connected. The output end of the motor 403 is fixedly connected to the rotating shaft 402. A moving tube 404 is slidably connected to the surface of the rotating shaft 402. On the arc surface of the moving tube 404, a first seeding wheel 405, a second seeding wheel 406 and a third seeding wheel 407 are fixedly connected. A number of material grooves 408 are formed on the arc surfaces of the first seeding wheel 405, the second seeding wheel 406 and the third seeding wheel 407. The number of material grooves 408 on the first seeding wheel 405, the second seeding wheel 406 and the third seeding wheel 407 increases in sequence. A feeding tube 409 is fixedly connected to the lower surface of the seeding box 3. The inner wall of the feeding tube 409 is movably connected to the third seeding wheel 407. A limiting rod 410 is threadedly inserted into the arc surface of the moving tube 404. A number of limiting holes 412 are formed in the surface of the rotating shaft 402 at positions corresponding to the limiting rod 410. The inner wall of one of the limiting holes 412 is slidably connected to the limiting rod 410. Operate the first seeding wheel 405, the second seeding wheel 406 and the third seeding wheel 407 with the number of material grooves 408 increasing in sequence, and select the corresponding seeding wheel according to the needs and install it into the feeding tube 409 to change the seeding amount of the rice seeding machine. The operation is simple and convenient. One end of the limiting rod 410 away from the moving tube 404 is fixedly connected with a number of anti-slip protrusions 411. The number of anti-slip protrusions 411 is evenly distributed on the arc surface of the limiting rod 410. The friction of the operating end of the limiting rod 410 is increased through the anti-slip protrusions 411, which is convenient for the user to rotate the limiting rod 410. A number of marking grooves 413 are formed on one side of the rotating shaft 402 close to the limiting holes 412. The number of marking grooves 413 is evenly distributed on the rotating shaft 402. Align one end of the moving tube 404 with the marking groove, so that the limiting rod 410 is aligned with the limiting hole 412, which is convenient for the user to operate the limiting rod 410 to slide into the limiting hole 412. On one side of one of the support plates 401 close to the motor 403, a protective cover 414 is fixedly connected. The motor 403 is shielded and protected through the protective cover 414 to prevent a large amount of smoke and dust from eroding the motor 403;

[0032] In an embodiment of the present invention, please refer to Figure 4 and Figure 5, the auxiliary structure 5 includes an auxiliary frame 51. The auxiliary frame 51 is fixedly connected to the bracket 1. A tilling frame 52 is slidably connected to the inner wall of the auxiliary frame 51. A positioning frame 53 is slidably connected to one side of the auxiliary frame 51. A plurality of positioning holes 54 are formed in one side of the tilling frame 52 at the position corresponding to the positioning frame 53. The inner wall of one of the positioning holes 54 is slidably connected to the positioning frame 53. A fixing rod 55 is fixedly connected to the side of the auxiliary frame 51 close to the positioning frame 53. The arc surface of the fixing rod 55 is slidably connected to the positioning frame 53. A spring 56 is sleeved on the arc surface of the fixing rod 55. The two ends of the spring 56 are respectively fixedly connected to the fixing rod 55 and the positioning frame 53. According to the looseness of the soil, the tilling frame 52 is operated to extend downward out of the auxiliary frame 51, changing the tilling depth of the tilling frame 52. The adjustment operation is simple and convenient, and the practicability is high. The end of the positioning frame 53 close to the auxiliary frame 51 is arc-shaped. The end of the positioning frame 53 close to the auxiliary frame 51 is arc-shaped, which is convenient for the positioning frame 53 to slide into the positioning hole 54. A pulley 57 is rotatably connected to the lower surface of the auxiliary frame 51. The arc surface of the pulley 57 is slidably connected to the tilling frame 52. The friction between the tilling frame 52 and the inner wall of the auxiliary frame 51 is reduced through the pulley 57, making the tilling frame 52 move more smoothly along the auxiliary frame 51;

[0033] The working principle of a rice seeder with adjustable seeding amount provided by the present utility model is as follows: By setting the adjustment structure 4, first rotate the limit rod 410. The limit rod 410 moves along the moving pipe 404 in the direction away from the rotating shaft 402 by means of the thread until the limit rod 410 completely slides out of the limit hole 412, releasing the limit on the moving pipe 404. Move the moving pipe 404 in the direction away from the motor 403. During this process, the moving pipe 404 drives the first seeding wheel 405, the second seeding wheel 406, and the third seeding wheel 407 away from the motor 403. Among them, the third seeding wheel 407 gradually slides out of the inner wall of the feeding pipe 409, and the second seeding wheel 406 gradually slides into the inner wall of the feeding pipe 409. When the second seeding wheel 406 is located at the center of the feeding pipe 409, rotate the limit rod 410 in the reverse direction. The limit rod 410 moves along the moving pipe 404 in the direction close to the rotating shaft 402 by means of the thread, and the limit rod 410 slides into the corresponding limit hole 412. Start the motor 403. The motor 403 drives the moving pipe 404 and the second seeding pipe to rotate through the rotating shaft 402. At this time, the seeding amount is reduced. Similarly, operate the first seeding wheel 405 to be loaded into the feeding pipe 409 to further reduce the seeding amount. Among them, the friction of the operating end of the limit rod 410 is increased through the anti-slip protrusion 411, which is convenient for the user to rotate the limit rod 410. One end of the operating moving pipe 404 is aligned with the marking groove, and then the limit rod 410 is aligned with the limit hole 412, which is convenient for the user to operate the limit rod 410 to slide into the limit hole 412. The motor 403 is shielded and protected by the protective cover 414 to prevent a large amount of soot from eroding the motor 403.

[0034] By setting the auxiliary structure 5, first move the positioning frame 53 in a direction away from the auxiliary frame 51. During this process, the arc surface of the positioning frame 53 gradually moves away from the positioning hole 54 along the auxiliary frame 51. The positioning frame 53 always slides along the arc surface of the fixed rod 55, and the spring 56 is in a compressed state. When the positioning frame 53 completely slides out of the positioning hole 54, the limit on the soil tilling frame 52 is released. Move the soil tilling frame 52 downward to an appropriate distance, then release the positioning frame 53. The positioning frame 53 moves in a direction close to the auxiliary frame 51 under the action of the elastic force of the spring 56, and the positioning frame 53 slides into the corresponding positioning hole 54 to fix the position of the soil tilling frame 52. Among them, one end of the positioning frame 53 close to the auxiliary frame 51 is arc-shaped, which is convenient for the positioning frame 53 to slide into the positioning hole 54. The friction between the soil tilling frame 52 and the inner wall of the auxiliary frame 51 is reduced by the pulley 57, making the soil tilling frame 52 move more smoothly along the auxiliary frame 51.

[0035] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated herein.

[0036] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
