Background

Sorghum is the main raw material for producing white spirit. The sorghum grain mainly contains a certain amount of tannins besides a large amount of starch, a proper amount of protein and minerals required for brewing wine. Proper amount of tannin has certain inhibition effect on harmful microorganisms in the fermentation process, and can improve the wine yield. Aromatic substances such as syringic acid and syringaldehyde generated by tannin can also increase the aromatic flavor of the white spirit.

In the prior art, the agricultural seeding machine realizes high-speed precision seeding, and adopts an air suction type seeding disc to sow mature seeds of large and medium crops, such as corn, soybean and the like. However, aiming at the problem that the precision seeding effect is poor when small seeds are sown, the problem comprises the sowing of the brewing sorghum, and mainly because on one hand, the small brewing sorghum seeds are easy to cause one hole to suck more, thereby causing one hole to suck more plants and affecting the actual growth of the brewing sorghum; on the other hand, if the small-sized brewing sorghum seeds only pursue one pit and one grain, the top soil capability of the seeds is different due to different soil topography, so that the phenomena of seedling shortage and ridge breakage are caused. Therefore, in production, for small-sized brewing sorghum seeds, a large-scale direct seeding device for the brewing sorghum is needed, and a seeding tray which accords with the emergence characteristics of the brewing sorghum seeds is provided, so that efficient seeding of the brewing sorghum is ensured.

The specific use is as follows: sorghum seeds enter the feed channel 423, as can be seen from fig. 6, 7, 10, 11 and 12, the bottom end of the feed channel 423 is communicated with the inside of the circular notch 422, the outer wall of the sowing disc 425 is tightly attached to the circular notch 422, and along with the rotation of the sowing disc 425, the conical feed holes 4252 on the sowing disc 425 are communicated with the feed channel 423 one by one, so that the seeds inside the feed channel 423 enter the conical feed holes 4252 on the sowing disc 425 from the bottom end of the feed channel 423; with the continued rotation of the seeding tray 425, the conical feed hole 4252 previously filled with seeds is communicated with the lower discharge channel 424, so that the seeds in the conical feed hole 4252 fall into the discharge channel 424 and fall onto the soil through the lower discharge channel in the lower housing 43, thereby completing the seeding of the brewing sorghum;

Meanwhile, the suction hole 4271 on the connecting disc 427 is located at the upper half part of the connecting disc 427, which corresponds to the upper half part between the feeding channel 423 and the discharging channel 424, so that when one of the conical feeding holes 4252 is communicated with the feeding channel 423 and receives seeds along with the rotation of the seeding disc 425, the inside of the conical feeding hole 4252 is communicated with the suction hole 4271 at the upper half part through the branch hole 4254, the air cavity 4251, the connecting hole 4255 and the hole 4256 along with the rotation of the conical feeding hole 4252, and negative pressure is generated, so that the materials in the conical feeding hole 4252 are adsorbed (in the embodiment, the rotation of the seeding disc 425 is set to rotate clockwise, namely, the suction hole 4271 on the connecting disc 427 is set to rotate clockwise, and if the rotation directions are opposite, the positions of the feeding channel 423, the discharging channel 424 and the suction hole 4271 are changed adaptively), and as the conical feeding hole 4252 continues to rotate, when the conical feeding hole 4252 is communicated with the discharging channel 424, the negative pressure effect is lost, and the seeds fall under the action of gravity.

Further, the position of the conical block 4253 in the conical feed hole 4252 can be changed through the driving member 5, so that the size of the capacity of receiving seeds in the conical feed hole 4252 is changed, in an initial state, as shown in fig. 11, the conical block 4253 in the conical feed hole 4252 is positioned closest to the outside of the sowing tray 425, at the moment, the capacity of receiving seeds in the conical feed hole 4252 is only a bit at the upper half part, the capacity of the conical feed hole is enough to accommodate one sorghum seed, and the two sorghum seeds cannot be accommodated, and at the moment, the sowing tray 425 can sow single sorghum seeds by utilizing the arrangement of the conical block 4253 at the position, so that various phenomena of one hole are avoided; when the position of the conical block 4253 is changed by using the driving piece 5, the conical block 4253 moves towards the center of the sowing disc 425, so that the capacity of the conical feeding hole 4252 at the upper half part is changed, the space is larger, and the accommodation of multiple seeds is further satisfied, so that the quantity of seeds in sowing can be adaptively changed according to different environments in different areas, and precision sowing is realized;

Meanwhile, due to the particularity of the shapes of the conical block 4253 and the conical feed hole 4252, the conical block 4253 can be moved for a small distance to realize receiving and containing of multiple seeds, so that the device is more suitable for different scenes, not only can seed sorghum seeds, but also can realize precise seeding for seeds with larger particle size, has wider use scenes, improves the use portability of the whole device, and realizes the effect of one machine for multiple purposes;

In addition, it should be noted that, the movement of the conical block 4253 can limit and influence the size of the conical feed hole 4252, and the slit on the conical block 4253 can solve the problem, and the material of the conical block 4253 is set to be an elastic material, so as to further satisfy the movement of the conical block 4253; and when the slit on the conical block 4253 is at the maximum limit, the size of the slit is still smaller than that of the single sorghum seed, so that the seed is prevented from being blocked into the slit, and the efficient use of the sowing tray 425 is ensured.

Further, a central cavity 4257 is provided at the center of the interior of the seeding tray 425;

The driving piece 5 comprises a driving disc 51, a guide rod 52 and a limit spring 54; wherein:
