[0032] See also Figure 1-7 , a seeder groove wheel control device, comprising:

[0033] The installation box 1 has an installation cavity 10 formed therein;

[0034] A seed box 2 is attached to the installation box 1 and is provided in plurality. Each seed box 2 is provided with a seed inlet 20 and a seed discharge port 21 in sequence from top to bottom in the vertical direction.

[0035] The sheave 3 includes a wheel axle 30 disposed in the installation cavity 10 and fixedly connected to the installation box 1, and a plurality of slot bodies 31 connected to the wheel axle 30 in a uniform and coaxially rotatable manner along the length of the wheel axle 30. Each slot body 31 includes a first bearing 310 and a slot body 311. The inner ring of the first bearing 310 is coaxially fixed to the wheel axle 30, and the seed slot body 311 is coaxially fixed to the outer ring of the corresponding first bearing 310. Each slot body 31 is correspondingly wrapped in a box 2 and close to the seed discharge port 21.

[0036] The driving assembly 4 includes a motor 40, a driving gear 42, and a driving shaft 41 drivingly connected to the output shaft of the motor 40. The driving shaft 41 has one end located in the installation cavity 10 and the other end extending outside the installation cavity 10 and drivingly connected to the motor 40 arranged outside the installation cavity 10. The driving shaft 41 is rotationally connected to the installation box 1. The driving gear 42 is coaxially fixed to the end of the driving shaft 41 located in the installation cavity 10. A plurality of driving gears 42 are provided.

[0037] The transmission assembly 5 includes a transmission shaft 50 disposed in the installation cavity 10 and rotatably connected to the installation box 1, and a plurality of transmission members 51 slidably connected to the transmission shaft 50;

[0038] The slot body 31 , the driving gear 42 and the transmission member 51 correspond to each other one by one, and each transmission member 51 is used for transmission connection between the corresponding driving gear 42 and the slot body 31 .

[0039] The seeder slot wheel control device provided by the present invention can simultaneously sow in the same row of cultivated land furrows by arranging multiple slot bodies on the same wheel axle; at the same time, by arranging the slot bodies, driving gears and transmission members in a one-to-one correspondence, each transmission member is used to drive and connect the corresponding driving gear and the slot body, and can respectively control the rotation of the corresponding slot body by a transmission member, thereby controlling the corresponding seed box to sow; when sowing is not needed, the corresponding slot body can be controlled to disconnect the transmission connection with the corresponding driving gear by sliding a separate transmission member, thereby realizing separate control of different slot bodies on the same wheel axle, and then when sowing in multiple rows of cultivated land furrows, it is convenient to control sowing in each row, not sowing, sowing different seeds, intermittent sowing, etc., thereby expanding the application scope of its actual production operation.

[0040] Specifically, each trough body 31 also includes a first gear 312 coaxially fixed to the outer ring of the corresponding first bearing 310, and each transmission member 51 is used to transmit and connect the corresponding driving gear 42 and the first gear 312. When the sliding transmission member 51 is connected to the driving gear 42 and the first gear 312, the corresponding trough body 31 can rotate, thereby realizing independent control of seeding.

[0041] Specifically, the transmission member 51 includes a transmission gear 510, a second bearing 511, and a pull rod 512 that coaxially slide on the transmission shaft 50. The sliding connection between the transmission shaft 50 and the transmission gear 510 can be a keyway-matched sliding. The center of one end face of the transmission gear 510 protrudes to form a connecting portion 5100. The inner ring of the second bearing 511 is coaxially fixed to the connecting portion 5100. The outer ring of the second bearing 511 is fixed to one end of the pull rod 512. The other end of the pull rod 512 extends to the outside of the installation cavity 10 after passing through the pull hole 11 opened on the side wall of the installation box 1. In this way, by pushing the pull rod 512, the transmission gear 510 slides along the transmission shaft 50; the second bearing 511 is designed to enable the pull rod 512 to be pulled along the length direction of the transmission shaft 510 and to rotate the transmission gear 510; the lever 512 is connected to one end of the second bearing 511 to form an annular cover plate covering the end surface of the second bearing 511 facing away from the transmission gear 510, so that the force is more even when the lever 512 is pushed.

[0042] like Figure 1 In an optional embodiment of the transmission connection of the transmission member 51, each transmission gear 510 can slide along the transmission shaft 50 to simultaneously mesh with the corresponding driving gear 42 and the first gear 312.

[0043] like Figure 4In another optional embodiment of the transmission member 51 transmission connection, the transmission assembly 5 further includes a second gear 52 disposed in the installation cavity 10 and rotatably connected to the installation box 1, and a plurality of second gears 52 are provided and meshed with the first gear 312 one by one. A gap is left between each second gear 52 and the corresponding driving gear 42, and each transmission gear 510 can slide along the transmission shaft 50 to mesh with the corresponding driving gear 42 and the second gear 52 at the same time. In this embodiment, the sliding direction of the transmission gear 510 along the transmission shaft 50 is opposite to that in the above embodiment.

[0044] Specifically, one end of the first bearing 310 fixed with the seed trough 311 is located in the seed box 2, and the other end of the first bearing 310 is fixed with the first gear 312 and extends to the outside of the seed box 2, so that the seed trough 311 in the seed box is not hindered from discharging seeds.

[0045] Specifically, a mounting opening is provided on one side wall of the mounting box 1, and the seed box 2 is sealed at the mounting opening and fixedly connected to the mounting box 1. In actual application, the mounting box 1 can be fixed on the main beam at the front end of the seed drill, and the lever 512 and the upper end surface of the mounting box 1 are extended into the cab, and a rotatable baffle 12 corresponding to the lever 512 is fixed on the upper end surface of the mounting box 1, and the baffle 12 is arranged on the pushing path of the lever 512. When the lever 512 completes the transmission connection between the trough body 31 and the motor 40, the baffle 12 is rotated to lock the position of the lever 512 to prevent the trough body 31 from being disconnected from the transmission connection with the motor 40 due to vibration during the seeding operation.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
