Description

Technical Field

[0001] This utility model belongs to the field of quantitative feeding technology, and more specifically, relates to a feeding device for a germination tank. Background Technology

[0002] Seed soaking and germination is a process in agricultural planting, referring to the soaking of slow-germinating seeds before sowing. The purpose of soaking is to allow the seeds to absorb water more quickly, reaching a moisture content suitable for normal germination. Dry seeds typically have a moisture content below 15%, exhibiting very weak physiological activity and remaining dormant. After absorbing water, the seed coat swells and softens, and dissolved oxygen enters the cells along with the water. Enzymes in the seed also begin to activate. Due to the action of enzymes, embryo respiration is enhanced, and the insoluble substances stored in the endosperm gradually transform into soluble substances, which are transported to the embryo along with the water. The embryo obtains water, energy, and nutrients, and under suitable temperature and oxygen conditions, the cells begin to divide and elongate, thus enabling the seed to germinate.

[0003] After soaking and germination, the germinated seeds generally need to be transferred from the germination equipment to seedling trays for subsequent seedling cultivation. To ensure good growth of the seeds in the seedling trays, the weight and flatness of the seeds need to be controlled to prevent excessive seed accumulation, which increases competition among seeds, affects the plant's ability to absorb nutrients and water, and thus hinders plant growth and development. At the same time, densely packed seeds will restrict root growth space, leading to root entanglement, twisting, and even death.

[0004] A search revealed a plug-in feeding device in patent CN222683272U. This application describes a vertically integrated feeding channel within a frame, with two vertically aligned inserts slidably disposed inside the frame. The alternating movement of these two inserts controls the opening and closing of the entire feeding channel for convenient feeding. Furthermore, when both inserts are simultaneously located within the feeding channel, a certain amount of storage space is created between them, enabling quantitative feeding.

[0005] For example, patent CN222683271U discloses a drawer-type feeding mechanism. This application uses a sliding plate to move back and forth, causing the receiving trough to switch between the inlet and outlet positions. When the receiving trough moves below the inlet, a feeding channel is formed between them; at this time, material enters the receiving trough through this feeding channel. As the sliding plate continues to move, the receiving trough and the inlet are misaligned, forming a certain amount of storage space within the receiving trough. Finally, when the receiving trough moves above the outlet, an outlet channel is formed between them, and the material in the quantitative storage space falls into the receiving tray through this outlet channel, thus completing the quantitative feeding operation.

[0006] Although the above-mentioned application can achieve quantitative seed feeding, it has been found in actual use that the seeds are not flat in the seedling tray and are prone to local accumulation, which is also not conducive to seedling growth. Utility Model Content

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] As mentioned in the background section, while existing quantitative feeding mechanisms can control the weight of seeds, the feeding method is mainly an opening and closing type, meaning the feeding operation is concentrated at the moment the feed box opens. This easily leads to uneven distribution of seeds in the seedling tray, resulting in localized accumulation. To address this, a conventional approach is to add a leveling mechanism to vibrate the seeds in the seedling tray to improve their flatness. However, this is clearly not conducive to cost savings or improved efficiency. Therefore, this invention aims to provide a feeding device that can simultaneously achieve quantitative feeding and high flatness.

[0026] The present invention will be further described below with reference to specific embodiments.

[0027] like Figure 1 As shown, a feeding device for a germination tank according to this embodiment includes a first conveyor line 100 and a feeding mechanism 200. The first conveyor line 100 is used to convey seedling trays 300. The feeding mechanism 200 is located above the first conveyor line 100 and is used to quantitatively and evenly spread the seeds falling from the germination tank (not shown in the figure) into the moving seedling trays 300.

[0028] refer to Figure 2 , Figure 5 As shown, the unloading mechanism 200 includes a mounting frame 210, a hopper 220 mounted on the mounting frame 210, and a second conveyor line 230. The hopper 220 is located above the second conveyor line 230, and a slot 221 is formed at the discharge port of the hopper 220, which forms a discharge channel with the conveyor belt 232 of the second conveyor line 230.

[0029] Specifically, the hopper 220 has a cone-shaped structure that is wider at the top and narrower at the bottom. Its discharge port is an opening formed by the bottom of the hopper 220's peripheral wall, and the slot 221 is located on the rear peripheral wall. Here, "front" and "rear" refer to the conveying direction of the conveyor belt 232. The end closer to the beginning of the conveyor belt 232 is the front, and the end closer to the end of the conveyor belt 232 is the rear.

[0030] In some embodiments, to ensure that seeds can only be discharged from the discharge channel, the gap between the portion of the bottom of the hopper 220's perimeter wall without the slot 221 and the conveyor belt 232 is generally no more than 2.5 mm. Preferably, it is 1.5 mm to 2.0 mm, for example, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, etc. At the same time, to prevent interference between the bottom of the perimeter wall and the conveyor belt 232, a certain distance must be maintained between them.

[0031] In this specific embodiment, the discharge port of the hopper 220 is a rectangular structure formed by four side plates. The slot 221 is located at the bottom of the side plate near the end of the conveyor belt 232, serving as the sole outlet for the seeds within the hopper 220. While there are gaps between the bottoms of the other three side plates and the conveyor belt 232, these gaps are smaller than the diameter of the germinated seeds and are insufficient for the seeds to leak out.

[0032] During operation, the germinated seeds fall from the germination tank into the hopper 220. Initially, since the conveyor belt 232 is stationary, the seeds accumulate in the storage space formed by the hopper 220 and the conveyor belt 232. As the second conveyor line 230 is activated, the conveyor belt 232 will carry some seeds out of the storage space through the discharge channel and continue to transport them. These seeds will eventually fall from the end of the conveyor belt 232. At this time, the seedling tray 300 located below will receive the seeds falling from the conveyor belt 232 under the transport of the first conveyor line 100.

[0033] In some embodiments, after a seedling tray is leveled, the second conveyor line 230 rotates in the opposite direction to send the seeds stuck to the end of the arc segment of the second conveyor line 230 back to the horizontal conveying surface, preventing the seeds stuck to the end of the second conveyor line 230 from falling to the ground or onto the first conveyor line 100 after the seedling tray leaves below the second conveyor line 230.

[0034] This embodiment provides a feeding device for a germination tank. Germinated seeds are first quantitatively discharged through a discharge channel and simultaneously spread evenly on a conveyor belt 232; then, they continuously fall from the end of the conveyor belt 232. Compared to the traditional instantaneous feeding mode, the sequential feeding mode used in this embodiment effectively improves the flatness of the seeds within the seedling tray 300.

[0035] In some embodiments, the hopper 220 is provided with an adjusting plate 240, which covers the slot 221. At the same time, the adjusting plate 240 is provided with a plurality of oblong holes, and the hopper 220 is provided with fastening holes at corresponding positions; the connecting bolts pass through the corresponding oblong holes and fastening holes in sequence to realize the adjustable connection between the adjusting plate 240 and the hopper 220.

[0036] In this embodiment, by setting an adjustment plate 240 at the slot 221, the height of the discharge channel can be flexibly adjusted to meet the uniform laying requirements of seeds of different thicknesses.

[0037] In some embodiments, a scraper section 260 is provided at the end of the conveyor belt 232, and the scraper section 260 has an inclined scraping surface for timely cleaning of seeds adhering to the conveyor belt 232. The scraper section 260 may be a scraper plate or a wire rope, and there is no specific limitation here.

[0038] refer to Figure 4 As shown, in one specific embodiment of the second conveyor line 230, the second conveyor line 230 includes a pair of frames 231 arranged opposite to each other and two rollers (not shown in the figure) disposed between the frames 231, with a conveyor belt 232 covering the two rollers. The two ends of the rollers are rotatably mounted on the corresponding frames 231 via bearings, and at least one roller is connected to a motor to provide power for the rotation of the conveyor belt 232.

[0039] In some embodiments, a through hole is provided on the side of the frame 231, and an opening window 234 can be bolted into the through hole. The opening window 234 is provided to facilitate periodic cleaning of the interior. At the same time, a connecting block 233 is provided on the outer side of the frame 231 for connecting with the mounting bracket 210.

[0040] refer to Figure 3 As shown, in one specific embodiment of the mounting frame 210, the mounting frame 210 includes a main body portion 211 surrounded by several columns. The top of the main body portion 211 is provided with a frame portion 212, and a connecting beam 213 is provided on its inner side near the bottom. The frame portion 212 is generally a rectangular structure surrounded by horizontal and vertical beams. The top of the hopper 220 extends into the frame portion 212 and is connected to the inner wall of the horizontal beams by bolts. The connecting beam 213 is used to connect to the connecting block 233 on the second conveyor line 230.

[0041] like Figure 2 As shown, in some embodiments, the mounting frame 210 is also connected to a transition connector 270, which is used to connect to the discharge end of the germination tank to fix the mounting frame 210. Simultaneously, the transition connector 270 also connects the feeding hopper 220 and the germination tank, so that the seeds after germination can fall directly into the feeding hopper 220. Of course, a switching valve, such as a pneumatic ball valve, needs to be provided between the transition connector 270 and the germination tank to facilitate control of the seed feeding timing.

[0042] Specifically, refer to Figure 7 As shown, the transition connector 270 is a hollow structure, which includes a flange 271 and a connecting plate 272 connected vertically. The connecting plate 272 covers the feed inlet of the hopper 220 and is connected to the top of the frame part 212 by bolts; while the flange 271 is used to connect to the discharge port of the germination tank.

[0043] Preferably, the inlet of the hopper 220 is flush with the top of the frame portion 212. This design ensures that the connecting plate 272 covers the inlet of the hopper 220 without creating an excessive gap in the height direction, effectively preventing seeds from leaking out from the connection point.

[0044] like Figure 2 As shown, in some embodiments, guide plates 250 are provided on both sides of the conveyor belt 232 near the end, which are used to guide and limit the seeds during the conveying process.

[0045] Specifically, refer to Figure 4 , Figure 6 As shown, the guide plate 250 includes a straight section 251 and a curved section 252 connected to each other. The free end of the straight section 251 extends to the location of the adjusting plate 240; the free end of the curved section 252 extends along the end of the second conveyor line 230 to at least the lower surface of the second conveyor line 230. The curved section 252 is located outside the scraper section 260. Additionally, a lug 253 is provided on the side of the straight section 251, and the guide plate 250 is mounted on the frame 231 via the lug 253 on its side.

[0046] Preferably, both the lug 253 and the frame 231 are provided with oblong grooves for the connecting bolts to pass through, and the two oblong grooves are perpendicular to each other. This design allows the guide plate 250 to be adjusted in both length and width directions. The length direction is the conveying direction of the conveyor belt 232, and the width direction is the direction perpendicular to the conveying direction.

[0047] It is worth mentioning that in this embodiment, since the object of quantification is seeds, which have certain individual differences, and most crops allow a certain range of emergence error during seedling cultivation, there is no need for strict and precise quantification. Instead, more emphasis is placed on the uniformity of batch sowing.

[0048] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
