Description

Technical Field

[0001] This utility model relates to the field of crop planting technology, specifically to an anti-static contour seed metering device. Background Technology

[0002] In modern agricultural production, the seed metering device, as a core component of sowing machinery, directly affects sowing quality and agricultural production efficiency. Precise and efficient seed metering is a key prerequisite for achieving uniform crop growth and improving yield and quality. With the continuous improvement of agricultural mechanization, the design and manufacturing technology of seed metering devices are also constantly advancing, and various new types of seed metering devices are emerging to meet the needs of different crops and planting conditions.

[0003] However, in actual use, static electricity has gradually become a significant factor affecting the normal operation of seed metering devices. During seed metering, frequent friction and contact separation occur between the seeds and the components of the metering device, and this mechanical action easily leads to the generation of static electricity. This is especially true when the seeds have different materials, shapes, and surface characteristics, which exacerbates the accumulation of static electricity. The presence of static electricity causes numerous malfunctions in seed metering devices. On the one hand, statically charged seeds adhere to the inner wall of the metering device, resulting in uneven seeding. In precision seeding, this uneven seeding can cause the planting density of crops to fall short of expectations, affecting the crop's growth space and nutrient absorption, thereby reducing crop yield and quality. On the other hand, static electricity can cause seeds to attract each other and clump together. This clumping phenomenon is particularly severe for some small seeds, such as vegetable and flower seeds, resulting in too many or too few seeds in the seed hole, making precise seeding impossible. Utility Model Content

[0004] The purpose of this invention is to solve the problem that seed metering devices in the prior art are easily affected by electrostatic interference, which leads to poor seed metering accuracy, poor uniformity, and ultimately a significant decline in seed metering quality. This invention provides an anti-static contour seed metering device.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: an anti-static contour seed metering device, which has a vertically arranged introductory component, a support cylinder, and a guide cylinder. The support cylinder contains a flipping component, which is driven by a first motor to select the seeds introduced by the introductory component to achieve uniform sowing. At the same time, it can transmit external humid air through the seeds and the flipping component.

[0006] The flipping component includes a flipping cylinder supported and driven by a first motor. The outer circumference of the flipping cylinder is uniformly provided with a plurality of contour grooves that can hold the seed, and the contour grooves are connected to through holes that penetrate the inner wall of the flipping cylinder.

[0007] As a further optimization of the antistatic contour seed metering device of this utility model: the inlet component includes a funnel cylinder fixedly disposed on the top of the support cylinder, and both sides of the funnel cylinder along the length direction of the flipping cylinder are inclined surfaces, with the lower side of the inclined surface corresponding to the flipping cylinder.

[0008] As a further optimization of the anti-static contour seed metering device of this utility model: two locking slots are provided on the inclined surface of the funnel cylinder on one side. The locking slots can be locked with the closing plate. The closing plate can protect the rotating cylinder and limit the flow of seeds to the rotating cylinder.

[0009] As a further optimization of the anti-static contour seed metering device of this utility model: an auxiliary component is fixedly provided on the inclined surface, which can assist the seeds in entering the contour groove.

[0010] As a further optimization of the anti-static contour seed metering device of this utility model: the auxiliary component includes a fixing plate bolted to the inclined surface, and a pressing brush is fixed on the fixing plate. The pressing brush can press the seeds into the contour groove by corresponding to the flipping cylinder.

[0011] As a further optimization of the anti-static contour seed metering device of this utility model: the support cylinder is provided with an adjustment component that can cover the rotating cylinder, and the adjustment component can adjust the coverage of the rotating cylinder.

[0012] As a further optimization of the anti-static contour seed metering device of this utility model: the adjusting component includes a movable cylinder that is slidably disposed on the support cylinder, and the movable cylinder is sleeved with the outer periphery of the rotating cylinder at the edge away from the second motor.

[0013] As a further optimization of the anti-static contour seed metering device of this utility model: the end of the movable cylinder away from the flipping cylinder is threadedly connected to an adjusting screw, which is driven by a first motor.

[0014] As a further optimization of the antistatic contour seed metering device of this utility model: the gap between the flipping cylinder and the support cylinder is larger than the seed particle size, so as to reduce the compression of the seeds.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes contour grooves on the outer circumference of a rotating cylinder to select and quantitatively discharge an appropriate amount of seeds. Simultaneously, through a through-hole penetrating the inner wall of the rotating cylinder and connecting to the contour grooves, the rotating cylinder, driven by a second motor, utilizes the difference in airflow between the inner and outer walls and the rotational speed difference to create negative pressure at the contour grooves, thus assisting in seed positioning and maintaining stable, uniform sowing. Furthermore, as the rotating cylinder rotates, it also introduces humid air from the outside into the contour grooves, and some of this humid air also enters the accumulated seeds. This significantly reduces static electricity between seeds and between seeds and the rotating cylinder, thereby greatly minimizing static interference during seed sowing that could lead to poor seeding accuracy, decreased uniformity, and ultimately a significant decline in seeding quality.

[0017] This invention uses a contour groove to position and rotate the seeds, eliminating the need for a small gap between the support cylinder and the outer periphery of the rotating cylinder. This significantly reduces the probability of seed breakage due to compression. Simultaneously, an auxiliary component on the inner wall of the funnel at the top of the support cylinder assists in pressing the seeds into the contour groove for positioning, thereby improving the stability of the seeds entering the groove while minimizing the probability of seed breakage due to compression.

[0023] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0024] like Figure 1As shown, an anti-static contour seed metering device comprises a vertically arranged inductive component 4, a support cylinder 2, and a guide cylinder 1. The inductive component 4 is fixed to a carrier via the support cylinder 2 and the guide cylinder 1. The inductive component 4 facilitates the pouring of seeds by workers and can store a certain amount of seeds, which are then fed into a rotating component 7 located within the support cylinder 2. The rotating component 7 rotates under the drive of a second motor 8 to select out some of the seeds delivered by the inductive component 4 and prevent most seeds from being stored within the inductive component 4. The seeds are then discharged onto the ground through the guide cylinder 1, achieving uniform seed sowing and thus increasing crop yield while saving seed quantity. The rotating component 7 includes a rotating cylinder 703 located within the support cylinder 2 and supported and driven by the second motor 8. The outer circumference of the rotating cylinder 703 is evenly provided with multiple contour grooves 701 similar in shape to the seeds. The contour groove 701 can hold the seed. During the seed's descent, the seed is positioned within the contour groove 701. As the corresponding contour groove 701 rotates downwards with the tilting cylinder 703, the seed separates from the contour groove 701 under gravity. Then, with the assistance of the carrier, the seed can be evenly distributed onto the ground. Figure 2 and Figure 3 As shown, the rotating cylinder 703 has a through hole 702 on its wall, corresponding to the contour groove 701 and penetrating the wall. During the rotation of the rotating cylinder 703, due to its thickness, a certain speed difference occurs between the rotational speed inside and outside the cylinder. Simultaneously, airflow between the inside and outside of the rotating cylinder 703 is not smooth. Based on Bernoulli's principle, the pressure is relatively low inside the rotating cylinder 703 where the flow velocity is higher, and relatively high on the outside where the flow velocity is lower. Under this pressure difference, combined with the structural characteristics of the through hole 702, a certain pressure is generated at the contour groove 701, thus exerting a pressure effect on the seeds and effectively reducing the probability of seeds falling out of the contour groove 701. Furthermore, during the rotation process, the through hole 702 allows the relatively humid air inside the support cylinder 2 to pass through the contour groove 701 and the through hole 702 and be discharged. This process can not only reduce the static electricity generated by friction between the seeds and the contour groove 701 to a certain extent, but also reduce the amount of static electricity between the seeds in the guide 4, thereby effectively weakening the adverse effects of static electricity on the sowing process.

[0025] The gap between the support cylinder 2 and the flipping cylinder 703 is larger than the seed particle size, so the probability of the seed being squeezed during the flipping process is greatly reduced, which in turn greatly reduces the probability of the seed being squeezed and broken.

[0026] The inlet component 4 includes a funnel cylinder 401 fixedly mounted on the top of the support cylinder 2. Two locking slots 402 are provided on the side wall of the funnel cylinder 401. These slots allow the closing plate 5 to pass through and close or open the funnel cylinder 401, enabling it to be opened during use and closed for protection after use. They also help control the flow rate of seeds entering the rotating cylinder 703, thus reducing the probability of seed damage caused by mutual compression between seeds. Both sides of the funnel cylinder 401 corresponding to the length of the rotating cylinder 703 have inclined surfaces 403. The lower side of the inclined surface 403 is positioned corresponding to the rotating cylinder 703. An auxiliary component 6 is provided on the inclined surface 403 near the locking slots 402. The auxiliary component 6 can push the seeds into the contour groove 701 for positioning. Simultaneously, the auxiliary component 6 can assist the humidified air introduced through the through hole 702 to further reduce the amount of static electricity generated between seeds or between seeds and the structure, thus further reducing the impact of seeds on sowing. The auxiliary component 6 includes a fixing plate 601 fixed to the inclined surface 403 by bolts. A pressing brush 602 is fixed on the fixing plate 601 and overlaps the outer periphery of the rotating cylinder 703. The pressing brush 602 is made of rubber. During the rotation of the rotating cylinder 703, the pressing brush 602 can squeeze the seeds to help them get into the contour groove 701 for positioning.

[0027] like Figure 4 As shown, an adjusting component 3 is slidably fitted onto the support cylinder 2. The adjusting component 3 can be mounted on the carrier and allows the user to easily adjust the coverage of the contoured grooves 701, thus enabling the user to control the amount of seeds discharged in a single rotation of the tilting cylinder 703 according to their needs. The adjusting component 3 includes a first motor 302 fixedly mounted on the carrier. The first motor 302 drives an adjusting screw 303 that rotates concentrically with the tilting cylinder 703. The adjusting screw 303 is threadedly connected to a movable cylinder 301 slidably mounted on the support cylinder 2, allowing the user to control the stable forward and reverse rotation of the adjusting screw 303 according to their needs. The forward and reverse rotation of the adjusting screw 303 drives the movable cylinder 301, under the constraint of the support cylinder 2, to cover different amounts of contoured grooves 701 to control the amount of seeds discharged.
