Abstract
Description
Technical Field
[0001] This utility model belongs to the field of Sorghum bicolor planting technology, and specifically relates to a seeding tray for planting Sorghum bicolor. Background Technology
[0002] Sorghum sorghum (Sorghum tannin) is an annual herbaceous plant belonging to the genus Sorghum of the Poaceae family. It possesses exceptional vitality, with a well-developed root system and thick adventitious roots at the base of its stems that can penetrate up to 2 meters underground. It thrives even in arid environments, making it crucial for the management of loess plateaus and grasslands. In areas where sorghum sorghum is planted, soil structure is significantly improved, as its root system helps stabilize sand dunes, prevent wind erosion, and reduce soil moisture. Furthermore, as a high-quality forage, sorghum sorghum is highly nutritious, containing abundant crude protein and minerals, and is palatable, promoting rapid growth in livestock. The seeds of sorghum sorghum are mostly oval, small, and brownish-brown.
[0003] With the rapid development of agricultural machinery in my country, especially in the field of sowing, different types of sowing devices are becoming increasingly sophisticated. For example, invention patent CN201911155172.5 discloses a pneumatic suction seeder for small and medium-sized seeds, including a seed box, a seed metering disc, a negative pressure air chamber shell, and a seed metering pipe. The negative pressure air chamber shell is fixedly installed on the seeder frame. An air chamber is located inside the negative pressure air chamber shell, and a negative pressure air passage is located at the top of the shell. A rotatable seed metering disc is installed at the bottom of the shell, driven by a motor. The seed metering disc has evenly spaced, circularly arrayed seed suction passages, with seed suction nozzles installed at the bottom of each passage. The seed box and seed metering pipe are fixedly installed on both sides of the seed metering disc. A seed filling slide is located at the bottom outlet of the seed box, and airflow blocking components are installed on the side walls of the air chamber. This invention utilizes negative pressure suction for seed transport, ensuring stable and efficient delivery, effectively reducing seed damage and missed or repeated sowing, and guaranteeing the seed metering efficiency of the seeder.
[0004] However, this pneumatic seeding device is expensive and highly mechanized, making it suitable for large-scale planting (over 50 mu), and the land types planted are mostly flat or gently sloping. For small and medium-sized farmers, the land is mostly scattered and the land types planted are mostly hilly, making it unsuitable for large-scale pneumatic seeding devices. Utility Model Content

Detailed Implementation
[0031] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The technical solutions of the present invention will be further described below with reference to the accompanying drawings of the embodiments. The present invention is not limited to the specific embodiments described below.

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0033] Please refer to Figures 1 to 8 A seeding tray for planting Sorghum sulphureus includes a set of seeding main boards 100 arranged opposite each other. The seeding main boards 100 are detachably connected, for example, by studs and nuts. A seeding cavity is reserved between the seeding main boards 100, and an inclined slide 110 is provided between the seeding main boards 100. The inclination angle of the inclined slide 110 can be freely set. A seeding tube 120 is provided below the inclined slide 110. The seeding tube 120 is flared, with one side of the flared opening facing upward. An arc-shaped limiting plate 130 is also provided between the seeding main boards 100.
[0034] See seed metering cylinder 200, see Figure 6 and Figure 7One end of the seed metering cylinder 200 passes through the seed metering main board 100 into the seed lowering cavity, and the seed metering cylinder 200 is located inside the arc-shaped limiting plate 130. A gap is reserved between the arc-shaped limiting plate 130 and the outer wall of the seed metering cylinder 200 to limit the movement of the sorghum seeds 710. Furthermore, the seed metering cylinder 200 and the inclined slide 110 are arranged close to each other, so that the sorghum seeds 710 cannot fall between the inclined slide 110 and the seed metering cylinder 200. The seed metering main board 100, the inclined slide 110, the seed metering cylinder 200 and the arc-shaped limiting plate 130 together form a triangular seed storage area, so that the sorghum seeds 710 are temporarily stored in the triangular seed storage area to prevent the seeds from falling to the ground.
[0035] The outer wall of the seed metering cylinder 200 is provided with a rolling bearing or annular bearing, and the inner wall of the seed metering cylinder 200 is provided with a rolling bearing or annular bearing. An annular through hole is opened on the side of the seed metering main plate 100. One end of the seed metering cylinder 200 is passed through the annular through hole into the seeding cavity. The rolling bearing is fixed on the seed metering main plate 100. At the same time, the inner cavity of the seed metering cylinder 200 is in a closed state.
[0036] Along the radial direction of the seed metering cylinder 200, at least one ring of seed storage holes 210 is provided through its surface (the seed storage holes are stepped holes, that is, the diameter of the seed storage holes 210 near the outer wall of the seed metering cylinder 200 is larger, and the diameter of this end is larger than the average diameter of Sorghum sulphureus, so that the seeds of Sorghum sulphureus will enter the seed storage holes 210, and only one Sorghum sulphureus seed 710 can be stored, while the diameter of the seed storage holes 210 near the inner wall of the seed metering cylinder 200 is smaller, and the diameter of this end is smaller than the average diameter of Sorghum sulphureus, so as to prevent the seeds of Sorghum sulphureus from directly entering the inner cavity of the seed metering cylinder 200). Therefore, the seeds of Sorghum sulphureus will be stored in the seed storage holes 210, thereby achieving the function of transporting a single Sorghum sulphureus seed 710.
[0037] See Figure 1 and Figure 5 The transmission component 300 is disposed on one side of the seed metering main board 100. The transmission component 300 is connected to the seed metering cylinder 200 and drives the seed metering cylinder 200 to rotate. The transmission component 300 can be connected to an existing device to realize transmission, such as the transmission component 300 being connected to the front furrowing plow blade, or the transmission component 300 being directly connected to the tractor, etc.
[0038] Because some Sorghum sulphureus seeds 710 have a diameter larger than the average diameter of Sorghum sulphureus, or some Sorghum sulphureus seeds have a diameter smaller than the average diameter of Sorghum sulphureus, when the Sorghum sulphureus seeds 710 enter the seed storage hole 210, they will get stuck in the seed storage hole 210, preventing them from falling out. This will occupy the space of the seed storage hole 210, preventing it from storing the remaining Sorghum sulphureus seeds 710, resulting in seed leakage. Therefore, a seed pushing component 400 is also included. The seed pushing component 400 is located between a group of seed dispensing main boards 100 and is disposed within the seed dispensing cylinder 200. The component 400 is connected to the transmission assembly 300. The seed pushing component 400 rotates synchronously with the seed metering cylinder 200 to push the seeds remaining in the seed storage hole 210 into the seed metering cylinder 200. When the seed metering cylinder 200 rotates, the seed pushing component 400 rotates synchronously. When the seed storage hole 210 of the seed metering cylinder 200 is located directly below, since the seed storage hole 210 is through-hole, one end of the seed pushing component 400 will extend into the seed storage hole 210 to push the sorghum seeds 710 stuck in the seed storage hole 210 into the seed metering cylinder 200 below, ensuring that the seed storage hole 210 can continue to store seeds in the next time. The pushing method of the seed pushing component 400 can include a rotary rolling pushing method, a multi-link rotary pushing method, or a pushing cylinder pushing up and down method. It is only necessary to push the sorghum seeds 710 stuck in the seed storage hole 210 into the seed discharging cylinder 200 below.
[0039] For details, see Figure 8Above the seed metering main board 100 is a seed storage box 700, which stores a number of Sorghum sulphureus seeds 710 (hereinafter referred to as seeds). Below the seed storage box 700 is a seed drop port, and the seed storage box 700 is equipped with a switch valve (the switch valve is existing technology and will not be described in detail here). The seed drop port is opened and closed at regular intervals by the switch valve for timed seeding. For example, the switch valve opens every 1 minute, and the seed drop port drops seeds. After 15 seconds of seeding, the switch valve closes, pre-storing only a certain amount of seeds in the triangular seed storage area to prevent excessive seeds in the triangular seed storage area from overflowing from the seed metering main board 100. Seeds falling from the seed outlet will enter the seed-feeding cavity reserved between a group of seed-feeding main boards 100, and will be temporarily stored in the triangular seed storage area formed by the seed-feeding main board 100, the inclined slide 110, the seed-feeding cylinder 200 and the arc-shaped limiting plate 130. The sorghum seeds 710 are temporarily stored in this triangular seed storage area. The inclined slide 110 is set in an inclined direction. Seeds falling on the inclined slide 110 will roll onto the surface of the seed-feeding cylinder 200 and fill the seed storage sink hole 210. As the transmission assembly 300 rotates, the seed dispensing cylinder 200 rotates clockwise, causing the seeds in the seed storage hole 210 to rotate. The seeds will enter the gap between the arc-shaped limiting plate 130 and the outer wall of the seed dispensing cylinder 200 (this gap is adjusted according to the diameter of the seeds; if the seeds are large, the gap is widened to limit the seeds, and vice versa). This will limit the seeds and prevent them from falling out prematurely. After the seeds rotate and flow out from this gap (i.e., rotate to the 6 o'clock position), the opening of the seed storage hole 210 faces downwards. A single seed will fall into the seeding tube 120 below for single-seed planting, and the planting will be carried out in a cyclical manner. If a seed gets stuck in the seed storage hole 210, since the seed pushing component 400 is connected to the transmission component 300, the seed pushing component 400 and the seed discharging cylinder 200 rotate synchronously. When each seed storage hole 210 rotates to the 6 o'clock position, the end of the seed pushing component 400 can just extend into the seed storage hole 210, pushing the seed stuck in the seed storage hole 210 into the seeding tube 120 below for single-seed planting.
[0040] This sorghum-sudangrass planting tray has a simple structure, is easy to inspect and repair, and has low maintenance costs, making it suitable for small and medium-sized farmers with scattered land. Simultaneously, the seed metering cylinder 200 enables uniform single-seed metering, ensuring even distribution of the sorghum-sudangrass seeds 710 in the soil, avoiding seed re-sowing and achieving reasonable crop density. Furthermore, the seed pushing component 400 can push out seeds stuck in the seed storage holes 210, preventing seeds from clogging the holes and avoiding missed sowing during the sowing process.
[0041] Further, see Figure 5 The transmission assembly 300 includes a bearing housing 310, a transmission main shaft 320, a star-shaped connecting rod 330, and a transmission gear 340. The bearing housing 310 is mounted on one side of the seed metering main plate 100, and a bearing is provided on the bearing housing 310. The transmission main shaft 320 is coaxially arranged with the seed metering cylinder 200, ensuring that the transmission main shaft 320 and the seed metering cylinder 200 rotate coaxially. One end of the transmission main shaft 320 is mounted on the bearing housing 310. Specifically, the transmission main shaft 320... One end is installed in the bearing of the bearing housing 310, the transmission main shaft 320 rotates synchronously with the bearing housing 310, the star-shaped connecting rod 330 is installed at the other end of the transmission main shaft 320, and the end of the star-shaped connecting rod 330 is connected to the seed metering cylinder 200. Specifically, there are several star-shaped connecting rods 330, and each star-shaped connecting rod 330 connects the transmission main shaft 320 and the seed metering cylinder 200 at the same time to ensure that the transmission main shaft 320 and the seed metering cylinder 200 are relatively fixed.
[0042] Specifically, the transmission gear 340 is connected to an existing device via a chain to achieve transmission, such as the transmission gear 340 being connected to the front furrowing plow blade via a chain, or the transmission assembly 300 being directly connected to the tractor, etc.
[0043] Further, see Figure 5 To ensure that the transmission main shaft 320 and the seed metering cylinder 200 rotate coaxially, the transmission assembly 300 also includes a positioning pin 350. The positioning pin 350 passes through the seed metering cylinder 200 and is detachably connected to the star-shaped connecting rod 330. By adjusting the positioning pin 350, the transmission main shaft 320 and the seed metering cylinder 200 can rotate on the same axis without rotational deviation, thus extending their service life.
[0044] For further description, see Figure 6 and Figure 8The seed-pushing assembly includes a transmission secondary shaft 410 and at least one set of transmission sleeves 420. The transmission secondary shaft 410 is connected to the transmission main shaft 320. The transmission secondary shaft 410 is located directly above the seed tube 120, i.e., the transmission secondary shaft 410 is positioned near the seed tube 120. The transmission sleeve 420 is coaxially sleeved with the transmission secondary shaft 410. A plurality of ejector rods 430 are evenly arranged on the outer surface of the transmission sleeve 420. In the vertical direction, the ejector rods 430 are correspondingly arranged with the seed storage hole 210. The ejector rods 430 push up to the seed storage hole 210 directly below the transmission sleeve 420. Specifically, when one of the seed storage holes 210 is located at the 6 o'clock position, the end of one of the ejector rods 430 extends into the seed storage hole 210. The seed storage hole 210 behind this one will cooperate with the next ejector rod 430 at the 6 o'clock position, thereby pushing out the seeds stuck in the seed storage hole 210. The length of the ejector rod 430 and the distance between the ends of two adjacent ejector rods 430 can be reasonably set by the distance between two adjacent seed storage holes 210 to make them match. This method can be implemented by existing methods, which will not be elaborated here.
[0045] Further, see Figure 5 The transmission assembly 300 further includes a first pulley 360, a second pulley 370, and a transmission belt 380. The first pulley 360 is sleeved on the transmission main shaft and located on the side away from the star-shaped connecting rod 330, while being located on the side close to the seeding main board 100, to avoid motion interference between the transmission belt 380 and the star-shaped connecting rod 330. The second pulley 370 is sleeved on one end of the transmission secondary shaft 410, and the first pulley 360 and the second pulley 370 are connected by the transmission belt 380.
[0046] Specifically, when the main drive shaft 320 rotates, it drives the first pulley 360 to rotate, which in turn drives the second pulley 370 to rotate via the drive belt 380. The second pulley 370 then drives the secondary drive shaft 410 to rotate, thus achieving synchronous rotation between the secondary drive shaft 410 and the main drive shaft 320. The rotation of the secondary drive shaft 410 drives the ejector rod 430 on the drive sleeve 420 to rotate. That is, when the seed metering cylinder 200 sows seeds, the ejector rod 430 will rotate synchronously to prevent seed jamming in the seed storage hole 210 and to prevent missed sowing.
[0047] As a preferred option, see Figure 6To prevent excess seeds from remaining on the surface of the seed metering cylinder 200 besides the seed storage hole 210, as the seed metering cylinder 200 rotates, some small seeds rolling on its surface may get stuck between the seed metering cylinder 200 and the arc-shaped limiting plate 130. If a large number of small seeds are stuck between the seed metering cylinder 200 and the arc-shaped limiting plate 130, it will brake the seed metering cylinder 200. Therefore, the seeding tray for planting Sorghum stenoptera also includes a seed cleaning brush 500. The seed cleaning brush 500 is arranged between a set of seed metering main plates 100 and is located directly above the seed metering cylinder 200. The seed cleaning brush 500 is stationary. When the seed metering cylinder 200 rotates, it will block and clean the small seeds on the surface of the seed metering cylinder 200, preventing small seeds from entering the gap between the seed metering cylinder 200 and the arc-shaped limiting plate 130.
[0048] Furthermore, the seed cleaning brush 500 includes a brush plate and a brush head. The brush plate is fixedly mounted on the seed metering main plate 100 and located directly above the seed metering cylinder 200. The brush head is detachably mounted on the brush plate. The brush head is provided with a plurality of hard dense filaments facing the inclined slide plate 110. A gap is left between the hard dense filaments and the seed metering cylinder 200 to prevent the hard dense filaments from directly contacting the seed metering cylinder 200 and damaging the brush head. The brush head is used to block and clean the seeds.
[0049] Further, see Figure 6 For furrows with wide row spacing, where two rows of Sorghum sulphureus seeds 710 need to be planted, the seed storage holes 210 are provided in two rings to accommodate the wide furrows and allow for the planting of two rows of Sorghum sulphureus seeds 710. The holes are staggered to ensure that the seeds are planted evenly in the furrows, which meets the purpose of reasonable dense planting.
[0050] For details, see Figure 6 When the seed storage sink hole 210 is provided with two rings, the transmission secondary shaft 410 is provided with two sets of transmission sleeves 420, and the lifting rods on the two sets of transmission sleeves 420 can push out the seeds in the seed storage sink hole 210.
[0051] Further, see Figure 7The seed storage hole 210 has a regular hexagonal cross-section. Based on seed drop experiments, when the seed pushing component 400 is not installed, both the circular and hexagonal seed storage holes 210 are used in the seed drop experiment. The volumes of the circular and hexagonal seed storage holes 210 are the same. 1 kg of seeds are used in the experiment. The seed metering cylinder 200 has 100 circular seed storage holes 210 on its surface. After 1000 seed drop experiments using the circular seed storage holes 210, and after all 1 kg of seeds have fallen, the results are consistent. In the seed dropping experiment, the seed jamming rate of the circular seed dropping hole 210 was 14.3%, meaning that seed jamming occurred in 143 out of 1000 seed dropping experiments. When the regular hexagonal seed dropping hole 210 was used for 1000 seed dropping experiments, the seed jamming rate of the circular seed dropping hole 210 was 0.5%, meaning that seed jamming occurred in 5 out of 100 seed dropping experiments. The seed jamming rate of the regular hexagonal seed dropping hole 210 was about 13.8% lower than that of the circular seed dropping hole 210. Therefore, the regular hexagonal seed dropping hole 210 can significantly reduce seed jamming and prevent seed leakage in the furrow.
[0052] Further, see Figure 2 and Figure 4 The sowing tray for planting Sorghum oleracea also includes a baffle assembly 600, which includes a sliding baffle 610, an adjusting pin 620, and a locking buckle 630. The sliding baffle 610 has a through hole and passes through the through hole of the seed metering main board 100 to fit against the outer surface of the seed metering cylinder 200. The sliding baffle 610 can move relative to the seed metering cylinder 200. The cross-section of the sliding baffle 610 is the same as the cross-section of the through hole, that is, the sliding baffle 610 can just pass through the through hole. The sliding baffle 610 can close a ring of the seed storage hole 210. The sliding baffle 610 has an adjusting hole 611. The adjusting pin 620 passes through the adjusting hole 611 and fits against the seed metering main board 100. The locking buckle 630 passes through the adjusting pin 620 and is fixed to the seed metering main board 100. Specifically, the sliding baffle 610 has two rows of adjustment holes 611, which are used to close the seed storage hole 210 to accommodate single-row planting mode (planting one row of seeds) and double-row planting mode (planting two rows of seeds).
[0053] Specifically, after the plow makes furrows, if the furrow width is only suitable for planting a single row of seeds, the sliding baffle 610 is adjusted to slide inwards, blocking one ring of the seed storage holes 210. This leaves only one ring of the seed storage holes 210 exposed on the seed metering cylinder 200, allowing for seed storage. The adjusting pin 620 passes through the corresponding adjusting hole 611 and is fixed to one side of the seed metering main board 100 by the locking buckle 630, thus fixing the sliding baffle 610 and preventing it from shifting. When the seed metering cylinder 200 rotates, the seed storage holes 210 of the seed metering cylinder 200 store seeds. After the seed is stored, only a single row of seeds can be planted through the seed storage holes 210 to adapt to the single-row planting mode. Similarly, after the plow makes furrows, if the furrow width is suitable for planting double rows of seeds, the locking buckle 630 is removed, the adjusting pin plate 620 is pulled out from the adjusting hole 611, and the sliding baffle 610 is pulled outwards, so that both rings of seed storage holes 210 on the seed metering cylinder 200 are fully exposed. The adjusting pin plate 620 is then passed through the corresponding adjusting hole 611 and locked by the locking buckle 630. When the seed metering cylinder 200 rotates, after the seeds are stored in the seed storage holes 210 of the seed metering cylinder 200, double rows of seeds can be planted through the seed storage holes 210 to adapt to the double-row planting mode.
[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
