Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to an automatic seeder for grain seedling trays. Background Technology

[0002] The automatic grain seedling tray seeder is a highly integrated and intelligent agricultural machinery device. By precisely controlling the sowing depth, spacing and seed quantity, it significantly improves the efficiency and uniformity of grain sowing, reduces labor costs and labor intensity, and provides efficient and stable technical support for large-scale and standardized grain seedling production.

[0003] In the process of transplanting grain seedlings, the seedlings cultivated in the seedling trays need to be transplanted. However, the traditional transplanting process has its own problems. Due to the lack of refined operating techniques and equipment, physical damage to the seedling roots and stems is easily caused, including but not limited to root breakage, epidermal damage and tissue tearing, which reduces the survival rate of seedlings after transplanting. Utility Model Content

[0004] The purpose of this invention is to solve the problem that transplanting operations in the prior art can easily damage the roots and stems of seedlings, thereby affecting the survival rate of transplanted seedlings, and to propose an automatic seeder for grain seedling trays.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic seeding machine for grain seedling trays, comprising a seedling tray, wherein a seedling isolation frame is provided inside the seedling tray, a sliding groove is provided on the bottom surface of the seedling tray, two base plates are slidably connected inside the sliding groove, electric push rods are fixedly installed on both sides of the seedling tray, the drive end of the electric push rod is fixedly connected to the corner of the base plate, and a transport frame is fixedly installed at both ends of the seedling tray.

[0006] Preferably, an adapter plate is fixedly connected to the corner of the base plate, and the drive end of the electric push rod is fixedly connected to one side of the adapter plate.

[0007] Preferably, positioning rods are symmetrically fixedly connected to both sides of the seedling tray.

[0008] Preferably, positioning plates are symmetrically fixedly installed on both sides of the seedling isolation frame, and one end of the positioning rod extends through the interior of the positioning plate.

[0009] Preferably, the seedling isolation frame includes several isolation panels and side panels, with the isolation panels connected perpendicularly to each other, and a positioning plate fixedly connected to one side of the side panel.

[0010] Preferably, the seedling isolation frame includes several isolation panels and side panels, with the isolation panels connected perpendicularly to each other, and a positioning plate fixedly connected to one side of the side panel.

[0011] Preferably, a support leg is fixedly connected to one side of the other end of the adapter frame, and a support plate is fixedly connected to the other end of the support leg.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the bottom plates at both ends are driven to slide smoothly out from the bottom of the seedling tray. After the bottom plates slide off, the soil wrapped in the film and the seedling fall vertically into the transplanting pit due to gravity. This effectively avoids the risk of mechanical damage to the seedling roots and stems during transplanting, ensures the integrity of the seedling root system from the root, and significantly improves the survival rate of transplanted seedlings.

[0014] 2. In this utility model, seedling isolation racks of corresponding specifications are selected; then the positioning plate on the seedling isolation rack is precisely aligned with the positioning rod in the seedling tray to ensure that the two are precisely matched in space. Seedling isolation racks of suitable size are selected for precise cultivation to meet the differentiated growth needs of different types of seedlings. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-3 As shown, this utility model provides an automatic seeder for grain seedling trays, including a seedling tray 1. A seedling isolation frame 2 is provided inside the seedling tray 1. A sliding groove 11 is provided on the bottom surface of the seedling tray 1. Two base plates 3 are slidably connected inside the sliding groove 11. Electric push rods 4 are fixedly installed on both sides of the seedling tray 1. The drive end of the electric push rod 4 is fixedly connected to the corner of the base plate 3. A transport frame 5 is fixedly installed at both ends of the seedling tray 1. A transition plate 31 is fixedly connected to the corner of the base plate 3. The drive end of the electric push rod 4 is fixedly connected to one side of the transition plate 31. The transport frame 5 includes two transition frames 51 and a transport rod 52. One side of the two transition frames 51 is fixedly connected to one side of the seedling tray 1. The transport rod 52 is fixedly connected between the two transition frames 51. A support leg 53 is fixedly connected to one side of the other end of the transition frame 51. A support plate 531 is fixedly connected to the other end of the support leg 53.

[0023] The specific setup and function of this embodiment are described below. An innovative mechanized transplanting scheme is adopted during the cultivation and transplanting of grain seedlings. Seedlings are cultivated at precisely set intervals within the seedling isolation frame 2. A biodegradable film is pre-wrapped around the soil to which the seedling roots are attached, forming a regular geometric cube structure. Once the seedlings reach a predetermined stage, a professional transport device is used to transfer the automatic seeder from the grain seedling tray to the outdoor planting area. The seeder is precisely positioned above the transplanting pit by accurately positioning and clamping the transport rod 52. The support legs 53 and support plate 531 in the transport frame 5 provide stable support for the seedling tray 1. Then, the electric push rod 4 is activated, driving the bottom plates 3 at both ends to slide smoothly out from the bottom of the seedling tray 1. After the bottom plates 3 slide off, the soil wrapped in the film and the seedlings fall vertically into the transplanting pit under gravity, thus completing the automated transplanting operation. This solution abandons the traditional method of transplanting with a shovel, effectively avoiding the risk of mechanical damage to the seedling roots and stems during transplanting. It ensures the integrity of the seedling root system from the root, significantly improves the survival rate of transplanted seedlings, and provides a reliable technical guarantee for the efficient planting of grains.

[0024] Example 2: Figures 1-4As shown, the automatic seeding machine for grain seedling trays of this utility model includes a seedling tray 1, a seedling isolation frame 2 is provided inside the seedling tray 1, a sliding groove 11 is provided on the bottom surface of the seedling tray 1, two base plates 3 are slidably connected inside the sliding groove 11, electric push rods 4 are fixedly installed on both sides of the seedling tray 1, the driving end of the electric push rod 4 is fixedly connected to the corner of the base plate 3, a transport frame 5 is fixedly installed at both ends of the seedling tray 1, positioning rods 12 are symmetrically fixedly connected on both sides of the seedling tray 1, positioning plates 21 are symmetrically fixedly installed on both sides of the seedling isolation frame 2, one end of the positioning rod 12 moves through the inside of the positioning plate 21, the seedling isolation frame 2 includes several isolation plates 22 and side plates 23, the several isolation plates 22 are perpendicularly and cross each other, and the positioning plate 21 is fixedly connected to one side of the side plate 23.

[0025] The overall effect of this embodiment is that, in diverse production scenarios of grain seedling cultivation, to meet the differentiated growth needs of different types of seedlings, precise cultivation can be implemented by selecting seedling isolation frames 2 of appropriate size. The specific operation process is as follows: First, based on factors such as seedling variety characteristics, growth cycle, and root development patterns, a seedling isolation frame 2 of the appropriate specification is selected; then, the positioning plate 21 on the seedling isolation frame 2 is precisely aligned with the positioning rod 12 in the seedling tray 1 to ensure that the two are precisely matched in spatial position; finally, the seedling isolation frame 2 is placed inside the seedling tray 1 in a stable and vertical manner to form a stable cultivation structure that meets the growth needs of seedlings, laying a standardized and regulated foundation for subsequent seedling cultivation operations.

[0026] The device's operation and working principle are as follows: An innovative mechanized transplanting scheme is employed during the cultivation and transplanting of grain seedlings. Seedlings are cultivated at precisely set intervals within the seedling isolation frame 2. A biodegradable film is pre-wrapped around the soil to which the seedling roots attach, forming a regular geometric cube structure. Once the seedlings reach the predetermined stage, a specialized transport device transfers the automatic seeder from the grain seedling tray to the outdoor planting area. The seeder is precisely positioned above the transplanting pit by the precise positioning and clamping of the transport rod 52. The support legs 53 and support plate 531 in the transport frame 5 provide stable support for the seedling tray 1. Then, the electric push rod 4 is activated, driving the bottom plates 3 at both ends to slide smoothly out from the bottom of the seedling tray 1. After the bottom plates 3 slide off, gravity causes the soil wrapped in the film and the seedlings to fall vertically into the transplanting pit, thus completing the automated transplanting operation.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
