[0048] The embodiment of the application provides an automatic seed supply device and method for supplying seeds to a seed metering device, which can realize continuous and efficient seed supply and improve the efficiency of seeding work.

[0049] As Figures 1-8As shown, the automatic seed supply device comprises seed boxes 1, seed carrying tubes 2, seed dropping tubes 3, seed guiding rotary discs 4 and seed collecting tubes 5. The seed carrying tubes 2, the seed dropping tubes 3 and the seed collecting tubes 5 have the same diameter and are sequentially connected from top to bottom to form a closed seed supply channel, so that the seed dropping space is large and the seed accumulation or loss can be avoided. The outer sides of the walls of the seed carrying tubes 2, the seed dropping tubes 3 and the seed collecting tubes 5 are provided with a plurality of spaced connecting ears 8. The connecting ears 8 at corresponding positions are connected by connecting members (such as bolts) to form the overall appearance of the automatic seed supply device.

[0050] The seed boxes 1 are used for containing seeds. The seed boxes 1 have seed feeding openings 11 and seed outlet openings 12. The seed outlet openings 12 are located at the bottom ends of the side walls of the seed boxes 1. The seeds can be added into the seed boxes 1 through the seed feeding openings 11, and the seeds can be discharged through the side walls of the seed boxes 1 through the seed outlet openings 12 instead of being discharged from the bottom, so that the irregular scattering of the seeds in the large space below the seed boxes 1 can be avoided.

[0051] The seed carrying tubes 2 are provided with a plurality of mounting positions 21. Each mounting position 21 corresponds to a seed box 1. The seed carrying tubes 2 are provided with seed dropping openings 22 which are arranged in a circular ring shape along the bottom edges of the seed carrying tubes 2, so that the plurality of seed boxes 1 can be sequentially communicated with the seed dropping openings 22, and the operation is simple and convenient.

The bottom ends of the seed collecting tubes 5 are connected to the bottom ends of the seed dropping tubes 3 and are in communication with the seed dropping tubes 3. The bottom ends of the seed collecting tubes 5 are in communication with seed discharge devices.

[0052] In this embodiment, the cross section of the seed blocking ring plate 41 is an open ring shape, and the gap 411 can be in communication from top to bottom with the seed outlet 12 and the seed falling outlet 22, and has a guiding effect on the falling trajectory of the seeds. Among them, the central angle of the gap 411 is correspondingly set according to the central angle of the seed outlet 12 of the seed box 1, and is generally set to be fully overlapped with the seed outlet 12 when the gap 411 rotates to a certain angle, at this time the seed has the maximum first seed supply amount, the seed supply efficiency is high, the speed is fast, and it is continuous seed supply. When the central angle of the gap 411 is smaller than the central angle of the seed outlet 12, the seeds in the seed box 1 fall one after another with the rotation of the gap 411, so by reducing the size of the gap 411 or rotating the gap 411 to control the degree of coincidence with the seed outlet 12, the falling speed of the seeds can be controlled.

[0053] The automatic seed supply device provided by the embodiment of the application is connected in sequence by the seed carrying pipe 2, the seed falling pipe 3 and the seed collecting pipe 5, and forms a closed seed supply channel, and the seed falling pipe 3 is shared by multiple seed boxes 1, the seed falling space is large, the seeds can be prevented from piling up or being lost, the seed supply to the seed metering device can be continuous and fast, and the work efficiency is improved. The gap 411 is arranged on the seed blocking ring plate 41 of the seed guiding turntable 4 for seed falling, which is beneficial to the complete supply of the seeds in the seed box 1 and avoids the influence of the remaining seeds on the seed supply amount; the seed outlet 12 is arranged at the bottom end of the side wall of the seed box 1, the gap 411 is arranged on the seed blocking ring plate 41, and the annular seed falling outlet 22 is arranged at the bottom end of the seed carrying pipe 2, and the gap 411 is arranged through the seed falling outlet 22, so that the seeds can slide along the inner walls of the seed carrying pipe 2 and the seed falling pipe 3 and fall into the seed falling pipe 3 and the seed collecting pipe 5, the falling path of the seeds is controlled, the overall structure is more compact, the space utilization rate is high, the seed guiding turntable 4 can be conveniently driven to rotate in the seed falling pipe 3, the falling path of the seeds is interfered with the rotation and driving control of the seed guiding turntable 4, the layout is beneficial to the whole, the appearance is simple, and the safety is high.

[0054] Preferably, the bottom wall of the seed box 1 is inclined downward toward the seed outlet 12.

[0055] As shown in Figure 4 and Figure 5 , the cross section of the seed box 1 is a fan ring shape, the seed outlet 12 of the seed box 1 is arranged between the bottom wall and the side wall and is flush with the bottom wall at the bottom end of the side wall, the width of the seed outlet 12 is equal to the width of the arc-shaped outer side wall, by arranging the bottom wall to be inclined downward toward the seed outlet 12, the seeds in the seed box 1 can slide out of the seed outlet 12 under the action of gravity, without additional power, and the sliding mode of the seeds from the side is compared with the seeds falling directly from the bottom of the seed box 1, the sliding friction between the seed outlet 12 and the seed blocking ring plate 41 is small, which is beneficial to the rotation control of the seed guiding turntable 4.

[0056] As preferred, the seed box 1 is provided with a first partition plate 13, which divides the inner cavity of the seed box 1 into multiple sub-cavities, each of which is in communication with the seed outlet 12.

[0057] For example, the embodiment shown in Figure 4 and Figure 5 The seed box 1 is provided with two first partition plates 13, which are longitudinally spaced apart along the inner cavity of the seed box 1, and the edges of the first partition plates 13 abut against the inner wall of the seed box 1. The top end of the seed box 1 is open as the upper seed inlet 11, and the first partition plates 13 divide the upper seed inlet 11 into three parts, so that the three sub-cavities can be respectively seeded and seeded. The first partition plates 13 are detachably connected with the seed box 1, so as to adjust the capacity of the inner cavity of the seed box 1, such as Figure 4 The bottom wall of the seed box 1 is provided with multiple sets of limiting blocks 14, each set of limiting blocks 14 has a gap between the two limiting blocks 14, and the first partition plate 13 can be inserted into the gap to be fixed. Each first partition plate 13 is limited and installed between the bottom wall of the seed box 1 by at least two sets of limiting blocks 14, which has good stability and is convenient for adjusting the capacity of the inner cavity by pulling out.

[0058] As preferred, the first partition plate 13 is provided with a through hole, and the multiple sub-cavities are in communication through the through hole. When the first partition plate 13 is multiple, the setting height of the through holes on the multiple first partition plates 13 decreases or increases in turn to form a stepped structure.

[0059] It can be understood that by setting the through holes with varying heights on the first partition plate 13, the number of seeds contained in the multiple sub-cavities formed by the multiple first partition plates 13 can be changed in turn, and only by the upper seed inlet 11 of the sub-cavity with the highest through hole can the seeds be added in multiple sub-cavities in turn. The effect is good and the capacity is determined, and the precision of the amount of seeds added is high.

The multiple second partition plates 23 divide the hanging plate 24 into multiple mounting positions 21.

[0061] For example, the embodiment shown in Figure 6 and Figure 7The second partition plate 23 divides the seed carrying tube 2 into multiple fan-shaped areas, each of which is used to install a seed box 1. It can be understood that the shape of the fan-shaped area is the same as that of the seed box 1, and when the seed box 1 is installed in the fan-shaped area, the outer side wall of the seed box 1 can abut against the inner wall of the fan-shaped area.
