[0022] Embodiment 1

[0023] like Figures 1 to 3 As shown, a specific embodiment of the utility model provides a new type of seed divider, which improves the minute accuracy and avoids blockage; specifically includes a casing 100 and a seed dividing mechanism; the seed dividing mechanism includes a pair of parallel arranged seed dividing wheels 200, the outer periphery of the seed dividing wheel 200 is provided with a seed dividing groove 210 which is circumferentially arranged and extends along the axial direction of the seed dividing wheel 200, each seed dividing groove 210 is provided with a spaced partition 220, and a receiving groove for receiving seeds is formed between adjacent partitions 220, and the seed dividing wheel 200 is transmission-connected with a driving module; a seed dividing chamber 110 for receiving the seed dividing wheel 200 is provided in the casing 100, and a plurality of discharge holes 120 penetrating the seed dividing chamber 110 are provided on both sides of the outer periphery of the casing 100, and a feed port 130 connected to the seed dividing chamber 110 is also provided at the position between the two seed dividing wheels 200 at the upper end of the casing 100.

[0024] like Figures 1 to 3As shown, through the above arrangement, a seeding chamber 110 is provided in the casing 100 in this embodiment, and two seeding wheels 200 can be arranged relatively in the seeding chamber 110, and the seeding wheels 200 can be relatively rotated by being driven by a driving module. After seeds are input into the seeding chamber 110 located at the upper end of the casing 100, the seeds fall into the area between the two seeding wheels 200 corresponding to the seeding chamber 110, and during the relative rotation of the seeding wheels 200, the seeds are evenly dropped into each receiving groove of each seeding groove 210, and when each receiving groove is rotated to be relative to the discharge hole 120, the seeds can be output to realize seeding. When in use, the specifications of the receiving groove and the discharge hole 120 can be adjusted as needed to meet the cultivation needs of different types, and the high adjustment flexibility facilitates application to different motion systems. The use of a wheeled structure for seeding can also avoid blockage, thereby improving seeding accuracy and efficiency. In actual applications, the number of sowing routes of the 120-minute discharge hole is between 2 and 10, realizing full-range sowing operation; it can also be equipped with an intelligent walking system to realize automated farming operations to save manpower time for farming, achieve small-scale mechanized automated agricultural operations, and help transform the original small-scale agriculture of individual labor into a small-scale mechanized individual operation mode.

[0025] like Figures 1 to 3 As shown, in order to facilitate technicians to maintain and clean the seeding wheel 200, this embodiment is provided with a front cover 160 for closing the seeding chamber 110 on the front face of the housing 100. After the front cover 160 is opened, the seeding chamber 110 can be opened to avoid cleaning the internal residues. The front cover 160 can be assembled by screw connection.

[0026] like Figures 1 to 3 As shown, the minute wheels in the seeding chamber 110 need to rotate relative to each other to realize the seeding operation. In order to ensure that the two minute wheels remain relatively stable, a bearing groove is provided on the side wall of the seeding chamber 110 of the housing 100 in this embodiment, and a thrust bearing 700 is installed in the bearing groove to abut against the end face of the seeding wheel 200. The thrust bearing 700 can withstand axial loads, limit axial displacement of the minute wheel, ensure seeding accuracy, and operate more stably.

[0027] like Figures 1 to 3 As shown, in this embodiment, the discharge holes 120 located on both sides of the housing 100 are arranged at intervals along the length of the seeding slot 210, and when the seeding gear rotates, the receiving slot can be directly opposite to the discharge holes 120, and adjacent discharge holes 120 are arranged in a staggered manner. In this way, the seeds after seeding can be evenly sprinkled from both sides of the housing 100, and the staggered arrangement allows the seeds to be staggeredly output, ensuring uniform sowing.

[0028] Embodiment 2

Specifically, the driving module includes a transmission shaft 300 connected to the seeding wheel 200, and the two transmission shafts 300 are provided with multiple pairs of transmission gear sets 400 meshing with each other, and one of the transmission shafts 300 is also connected to the motor module 500. In this way, when the motor module 500 is running, the two seeding wheels 200 are driven to rotate stably through multiple pairs of transmission gear sets 400, and the multiple sets of transmission gears adjust the gear structure to adjust the transmission ratio according to the needs, so as to control the discharging speed. In practical applications, the motor module 500 preferably selects a stepper motor. There are many methods for stepper motors to control gear structures. The control of different gear sets is preferably achieved by changing the frequency of the motor drive signal. At the same time, various types of gears such as different numbers of teeth and different modules are selected to meet different matching conditions to achieve full-range sowing operation. In order to reduce the transmission friction, a corresponding bearing structure should be provided on the transmission shaft 300.

[0030] like Figures 1 to 3 As shown, in this embodiment, a transmission chamber 140 for accommodating a transmission gear set 400 is provided in the housing 100, and the transmission chamber 140 is isolated from the seeding chamber 110. The transmission chamber 140 is provided for installing a transmission structure to ensure the operation stability of the transmission structure. In addition, in this embodiment, a motor frame 600 for installing a motor module 500 is provided outside the housing 100. In order to facilitate inspection and maintenance, in this embodiment, a rear cover 150 for closing the transmission chamber 140 is provided on the rear end face of the housing 100; after the rear cover 150 is opened, the internal transmission structure can be inspected and maintained, which is convenient for technicians to operate.

[0031] The inventor found in actual measurements that the device weighs less than 2 kg, is 170 mm at its longest point, 136 mm at its widest point, and 122 mm at its highest point. It can even be installed on a drone, with a maximum discharging speed of 320,000 grains per minute, and a slowest discharging speed of 32 grains per minute. During the sowing process, the motor can rotate forward or reverse to sow. When it gets stuck, the motor will automatically switch direction to avoid getting stuck. Actual measurements have not encountered any failure to work due to jamming, and the device has high practical value.
