DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to further explain the technical solution of the utility model, the following is elaborated in detail through specific embodiments.

[0023] Please refer to Figure 1-2 , the utility model provides an efficient seed discharging device for intelligent agriculture, including a feed bin 1, a bin cover 2, a roller sleeve 3, a drive motor 4, a seed discharging port 5 and a pushing and discharging device 6. The top edge of the feed bin 1 is hingedly installed with a bin cover 2, and the bin cover 2 covers the top opening of the feed bin 1. A roller sleeve 3 is rotatably installed in the inner bottom circular cavity of the feed bin 1. The front roller shaft of the roller sleeve 3 is rotationally connected to the feed bin 1, and the front roller shaft of the roller sleeve 3 is belt-driven by the drive motor 4. The drive motor 4 controls the roller sleeve 3 to rotate, and a pushing and discharging device 6 is arranged inside the roller sleeve 3.

[0024] Please refer to Figure 3-4, the present utility model provides an efficient seed metering device for smart agriculture. The pushing seed metering device 6 includes a cell 61, a seed storage bladder 62, a pushing roller 63 and a closing hole adjusting device 64. The outer surface of the roller sleeve 3 is provided with cells 61 which are through structures. The inner side wall of the roller sleeve 3 is adhesively provided with seed storage bladders 62. The number of seed storage bladders 62 is the same as that of the cells 61, and the seed storage bladders 62 cover the inner opening surfaces of the cells 61. The cells 61 and the inside of the seed storage bladders 62 are in mutual communication. A pushing roller 63 is arranged inside the roller sleeve 3. The roller sleeve 3 and the pushing roller 63 are in a non-contact state. The pushing roller 63 can make extrusion contact with the seed storage bladder 62. The rear end of the pushing roller 63 is rotatably connected to the feeding bin 1. When the cell 61 passes through the position where the pushing roller 63 is located, the seed storage bladder 62 will be squeezed and contracted by the pushing roller 63, so as to push the seeds in the seed storage bladder 62 outwards through the cell 61, avoiding the seeds from staying inside the cell 61. A closing hole adjusting device 64 is arranged inside the cell 61.

[0025] Further explanation, the position and direction of the pushing roller 63 correspond to the seed discharging port 5. When the cell 61 passes through the seed discharging port 5, the pushing roller 63 can simultaneously push and squeeze the seed storage bladder 62, enabling the cell 61 to smoothly release seeds through the seed discharging port 5, and the seed metering timing is more accurate.

[0026] Further explanation, the whole seed storage bladder 62 is made of natural rubber material. The natural rubber material has excellent resilience, enabling the seed storage bladder 62 to quickly return to its original shape after being squeezed by the pushing roller 63, and not easily affecting the subsequent loading of seeds.

[0027] Please refer to Figure 5-6 , the present utility model provides an efficient seed metering device for smart agriculture. The closing hole adjusting device 64, rubber plug 641, screw hole 642, pulling rod 643 and threaded head 644. The rubber plug 641 can be inserted and fixed inside the cell 61 to close the cell 61. A screw hole 642 is opened on the surface of the head end of the rubber plug 641. The bottom end of the pulling rod 643 is integrally provided with a threaded head 644. The threaded head 644 can be screwed into the screw hole 642, and then the rubber plug 641 can be pulled out from inside the cell 61 by means of the pulling rod 643, so that the cell 61 is dredged and restored to the working state.

[0028] Further explanation, the surface of the roller sleeve 3 is provided with no less than 2 circles of cells 61. The cells 61 are arranged equidistantly along the surface of the roller sleeve 3, enabling users to close the number of redundant cells 61 according to the sowing amount requirement, so as to realize the adjustment of the sowing amount.

[0029] Further explanation, the outer shape structure of the pulling rod 643 is in an L shape, making it more convenient to apply force for the pulling out action.

[0030] The working principle is as follows:

[0031] First, before use, first add seeds into the feeding bin 1 to ensure sufficient seed supply. Then close the bin cover 2 to prevent dust from entering. Next, connect the drive motor 4 to the power supply and the external control system, and then the sowing work can be carried out.

[0032] Second, during use, the drive motor 4 drives the roller sleeve 3 to rotate at a constant speed. During this process, the seeds in the feeding bin 1 will fall from the nest holes 61 into the seed storage sac 62. As the roller sleeve 3 rotates, the nest holes 61 will pass through the position of the pushing roller 63. At this time, the seed storage sac 62 is squeezed by the pushing roller 63 and contracts, so that the seeds in the seed storage sac 62 are pushed outwards through the nest holes 61, and the nest holes 61 release the seeds through the seed discharging port 5, thus realizing sowing, which can avoid seeds staying inside the nest holes 61, thereby improving the sowing accuracy.

[0033] Third, when it is necessary to adjust the sowing amount, first open the bin cover 2 and empty the seeds inside the feeding bin 1. Then take out the rubber plug 641, and then fix the rubber plug 641 into the nest hole 61 from the inside of the feeding bin 1 to seal the nest hole 61. Users can seal the number of redundant nest holes 61 according to the sowing amount requirement, so as to realize the adjustment of the sowing amount. There is no need to disassemble and replace parts, and the adjustment operation is convenient, further improving the sowing efficiency.

[0034] Fourth, when it is necessary to remove the rubber plug 641 from the nest hole 61, first open the bin cover 2 and empty the seeds inside the feeding bin 1. Then take out the pulling rod 643, and then screw the threaded head 644 into the screw hole 642 from the inside of the feeding bin 1 to assemble and fix the pulling rod 643 with the rubber plug 641. Then the rubber plug 641 can be pulled out from the inside of the nest hole 61 by means of the pulling rod 643, so that the nest hole 61 is dredged and restored to the usable state.

[0035] The above are only the preferred examples of the present invention and are not used to limit the present invention.
