Description

Technical Field

[0001] This utility model relates to the field of scallion breeding technology, and in particular to a roller-type scallion breeding device. Background Technology

[0002] Currently, scallion seedling cultivation mainly relies on manual labor, including sowing. This manual process is susceptible to the influence of climatic factors such as temperature and light, resulting in uneven seedling quality and growth, and making seedlings prone to pests and diseases. Therefore, manual seedling cultivation is unstable, labor-intensive, time-consuming, and inefficient. Compared to traditional methods, factory-based seedling cultivation is not only time-saving and labor-saving but also boasts a high seedling survival rate and facilitates mechanized transplanting. The standardized seedling trays used in mechanized scallion seedling cultivation create conditions for fully automated transplanting, promoting mechanized transplanting operations and representing an inevitable trend in mechanized scallion cultivation.

[0003] For example, utility model patent application number 202222785624.1 discloses a precision sowing device for scallion seedling tray cultivation. It achieves scallion seed sowing through the sequential operation of a front soil covering mechanism, a pressing roller mechanism, a sowing mechanism, and a rear soil covering mechanism. The sowing mechanism is driven by a sowing drive mechanism, which sequentially drives the seed metering roller and the seed filter brush via a first chain. Scallion seeds in the seed box fall into the seed guide groove on the inner wall of the seed box after passing through two seed limiting plates, then fall through the guide groove onto the surface of the seed metering roller and enter the holes on the surface of the seed metering roller. The sowing drive sprocket and the sprocket led out by the seed filter brush are connected by a chain, causing the seed metering roller and the seed filter brush to rotate relative to each other. The bristles on the surface of the seed filter brush sweep away the scallion seeds from the surface of the seed metering roller. The scallion seeds entering the holes rotate with the seed metering roller and sequentially fall into the holes on the surface of the seed tray. However, in the above-mentioned technical solutions, when obtaining scallion seeds, they rely on the seeds falling naturally onto the surface of the seed metering roller. When seeds accumulate at the seed box outlet, it is difficult to ensure that the seeds fall smoothly onto the seed metering roller. During seed cleaning, it can only be achieved by using a seed filter brush, which easily causes scallion seeds to splash, resulting in gaps on the surface of the seed metering roller. Both of these situations increase the seed accuracy on the surface of the seed metering roller, thereby increasing the voids during breeding, which is not conducive to precision breeding. Summary of the Invention

[0004] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a drum-type scallion breeding device.

[0005] A roller-type scallion breeding device includes a frame, a conveyor belt for conveying seed trays is installed on the top of the frame; a support is fixedly installed above the conveyor belt, and a soil-laying mechanism, a seed-pressing mechanism, a breeding mechanism, and a soil-covering mechanism are sequentially installed on the support.

[0006] The breeding mechanism includes a seed-collecting roller, a seed-cleaning component, a seed box, and an exhaust fan. The seed-collecting roller is rotatably mounted on a support along the short axis of the conveyor belt. The seed box is fixed above the support, with the outlet end at the bottom of the seed box fitting against the side wall of the seed-collecting roller. One end of the seed-cleaning component is fixedly connected to the support, and the other end is axially inserted into the seed-collecting roller along its end, so that the side of the seed-cleaning component seals the end of the seed-collecting roller. The seed-cleaning component does not rotate when the seed-collecting roller rotates, and its lower part fits against the inner wall of the seed-collecting roller. The exhaust fan is connected to the inside of the seed-collecting roller through a flexible hose along the side of the seed-cleaning component, so that the exhaust fan adsorbs the seeds discharged from the seed box onto the surface of the seed-collecting roller. When the seed-collecting roller rotates to its lowest point, the seed-cleaning component blocks the suction force of the exhaust fan, causing the seeds to fall into the seed tray due to their own gravity.

[0007] Preferably, the seed-taking roller has seed-taking holes on its side wall.

[0008] Preferably, the seed-taking hole has a hemispherical structure and is connected to the inside of the seed-taking roller.

[0009] Preferably, the seed cleaning assembly includes an end cap and a sleeve; the sleeve is built into the seed-collecting roller along the axis of the seed-collecting roller, one end of the sleeve extends out of the seed-collecting roller and is fixedly connected to a bracket, an air baffle plate is fixedly provided below the sleeve and slides against the inner wall of the roller, the end cap is fixed on the sleeve so that the end cap seals the open end of the seed-collecting roller, and the end cap is rotatably connected to the open end of the seed-collecting roller.

[0010] Preferably, the cavitation mechanism includes a cavitation roller, and cavitation protrusions for cavitation are evenly distributed on the outer wall of the cavitation roller.

[0011] Preferably, the pressure cavities are conical in shape.

[0012] Preferably, the frame is further equipped with a power mechanism, which includes a drive motor, a first driven wheel, and a second driven wheel; the first driven wheel is installed at the input end of the conveyor belt, the second driven wheel is installed at the input end of the pressing roller, and the output end of the drive motor is connected to the first driven wheel and the second driven wheel.

[0014] Preferably, a soil collection bin fixed to the frame is provided below the tail end of the conveyor belt.

[0015] Compared with the prior art, the roller-type scallion breeding device provided by this utility model can realize the continuous conveying of the seed trays through the conveyor belt installed on the top of the frame. The soil spreading mechanism, the hole pressing mechanism, the breeding mechanism and the soil covering mechanism are installed in sequence on the support, which can realize the continuous operation of soil spreading, hole pressing, breeding and soil covering. Multiple seed trays can be bred at the same time, with high breeding efficiency and convenient operation.

[0016] During breeding, the suction force generated by the exhaust fan adsorbs the seeds discharged from the seed box onto the surface of the seed-collecting roller, ensuring precise seed acquisition. During seed discharge, the seed-collecting roller rotates to its lowest point, and the seed-cleaning component blocks the suction force of the exhaust fan, causing the seeds to fall into the seed trays due to their own gravity, thus achieving precision breeding. Throughout the entire breeding process, air-suction precision breeding is achieved, effectively reducing the empty seed rate. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements 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.

[0029] Please refer to Figures 1 to 8 This utility model provides a roller-type seedling tray scallion breeding device, including a frame 01, a conveyor belt 02 installed on the top of the frame 01, which can be used to transport seedling trays; and a support 03 fixedly installed above the conveyor belt, on which a soil-laying mechanism 04, a hole-pressing mechanism 05, a breeding mechanism 06, and a soil-covering mechanism 07 are installed in sequence; it can realize continuous operation of soil-laying, hole-pressing, breeding, and soil-covering, and can breed multiple seedling trays at the same time, with high breeding efficiency and convenient operation.

[0030] The breeding mechanism 06 includes a seed-collecting roller 61, a seed-cleaning component 62, a seed box 63, and a blower 64. The seed-collecting roller 61 is rotatably mounted on a bracket 03 along the short axis of the conveyor belt. The seed box 63 is fixed above the bracket 03, and the outlet end of the bottom of the seed box 63 is in contact with the side wall of the seed-collecting roller 61. One end of the seed-cleaning component 62 is fixedly connected to the bracket 03, while the other end of the seed-cleaning component 62 is axially inserted into the seed-collecting roller 61 along its end, so that the side of the seed-cleaning component 62 seals the end of the seed-collecting roller 61. At the same time, the seed-cleaning component 62 does not rotate when the seed-collecting roller 61 rotates, and the lower part of the seed-cleaning component 62 is in contact with the inner wall of the seed-collecting roller 61. The exhaust fan 64 connects to the inside of the seed-collecting roller 61 via a flexible hose along the side of the seed cleaning assembly 62. The suction force generated by the exhaust fan 64 draws the seeds discharged from the seed box 63 onto the surface of the seed-collecting roller 61. When the seed-collecting roller 61 rotates to its lowest point, the seed cleaning assembly 62 blocks the suction force of the exhaust fan 64, causing the seeds to fall into the seed tray due to their own gravity, thus achieving precision breeding. Throughout the breeding process, air-suction precision breeding is achieved, effectively reducing the empty seed rate during breeding.

[0031] In one embodiment, a seed-collecting hole 611 is provided on the side wall of the seed-collecting roller 61. The seed-collecting hole 611 can be hemispherical and communicate with the interior of the seed-collecting roller 61. Two seed-collecting holes 611 can be used as a group, with each hole 611 capable of holding just one seed. When the seed is placed into the groove on the seed tray 10, the seed is completely contained within the groove.

[0032] In one embodiment, the seed cleaning assembly 62 includes an end cap 621 and a sleeve 622. The sleeve 622 is built into the seed-collecting roller 61 along its axis, with one end extending out of the roller and fixedly connected to the bracket 03. An air baffle 623 is fixedly disposed below the sleeve 622, slidingly conforming to the inner wall of the seed-collecting roller 61. The air baffle 623 isolates the seed-collecting holes 611 on the seed-collecting roller 61 from the interior of the roller 61, allowing the seeds in the holes 611 to escape the suction force generated by the exhaust fan 64. The end cap 621 is fixed to the sleeve 622, sealing the open end of the seed-collecting roller 61. A sealing structure can be provided between the end cap 621 and the end of the seed-collecting roller 61 to prevent air leakage. To ensure that the baffle plate 623 does not rotate with the seed-collecting roller 61, the end cap 621 is rotatably connected to the open end of the seed-collecting roller 61. When the seed-collecting roller 61 rotates, the baffle plate 623 can block the suction force of the exhaust fan 64 at the lowest point of the seed-collecting roller 61. The area blocked by the baffle plate 623 can be determined according to the requirements. Under normal circumstances, the maximum blocking area of ​​the baffle plate 623 is half of the inner wall of the seed-collecting roller 61, that is, the position of the baffle plate 623 is the left or right half of the inner wall of the seed-collecting roller 61.

[0033] In one embodiment, the pressing mechanism 05 includes a pressing roller 51, on the outer wall of which are evenly distributed pressing protrusions 52 for pressing pits. The pressing protrusions 52 correspond to the seed holes 611, so that the seeds can be completely placed in the pits pressed out by the pressing protrusions 52. Of course, in order to facilitate pressing out pits into the substrate layer on the seed tray 10 and to ensure the formation rate of the pressed pits, the pressing protrusions 52 adopt a conical structure, which can facilitate the insertion of the pressing protrusions 52 into the substrate layer, while ensuring that the opening diameter of the pit is large and the bottom diameter is small.

[0034] In one embodiment, a power mechanism 08 is also mounted on the frame 01. The power mechanism 08 includes a drive motor 81, a first driven wheel 82, and a second driven wheel 83; wherein the drive motor 81 can be a variable frequency motor. The first driven wheel 82 is mounted on the input end of the conveyor belt 02, and the second driven wheel 83 is mounted on the input end of the pressing roller 51. The output end of the drive motor 81 is connected to the first driven wheel 82 and the second driven wheel 83. In this embodiment, the first driven wheel 82 and the second driven wheel 83 are driven by a chain; of course, a drive belt can also be used.

[0035] In one embodiment, a third driven wheel 20 is installed at the output end of the pressing roller 51, and a fourth driven wheel 30 is installed at the input end of the seed taking roller 61. The third driven wheel 20 and the fourth driven wheel 30 are connected. In this embodiment, the third driven wheel 20 and the fourth driven wheel 30 are driven by a chain; of course, a drive belt can also be used.

[0036] In one embodiment, to prevent the substrate on the seed tray 10 from falling onto the conveyor belt 02 and causing waste, a soil collection bin 09 fixed to the frame 01 is provided below the tail end of the conveyor belt 02. The soil collection bin 09 can collect the substrate on the conveyor belt 02 for subsequent reuse.

[0037] Of course, for the soil spreading mechanism 04 and the soil covering mechanism 07, a holding chamber is usually used to hold the substrate. A gate valve is usually installed at the bottom outlet of the holding chamber, and the amount of substrate flowing out is controlled by controlling the opening of the gate valve. To ensure that the substrate on the seed tray 10 is flat, a scraper or soil brush is usually installed at the bottom of the holding chamber.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
