Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a seedling tray perforator. Background Technology

[0002] The plug seedling technology was introduced from the United States in the last century and has become mature and perfected after more than 30 years of development. This technology uses lightweight soilless substrate materials such as peat moss and vermiculite as seedling substrates and plug trays as seedling containers. It has the advantages of saving labor, reducing costs, and increasing efficiency. It is convenient for the promotion of superior varieties and standardized seedling management. The seedlings are also easy to transport over long distances and transplant by mechanization. After transplanting, the root system is vigorous and the seedlings recover quickly. Therefore, it is favored by vegetable and flower producers and has become the main method of professional commercial seedling production in many countries.

[0003] Existing seedling tray punching methods rely on handheld punching rods to operate one hole at a time, which is inefficient (average 0.5 seconds / hole), labor-intensive, and has a depth error of ±3cm. Most punching machines on the market adopt a fixed depth design, which cannot adapt to the needs of different crop seeds (such as tomatoes requiring 3cm and peppers requiring 2.5cm). Therefore, a seedling tray punching device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a seedling tray puncher to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A seedling tray puncher includes a fixed frame and support legs. The support legs are fixedly connected to the bottom of the fixed frame. Symmetrically arranged support rods are fixedly connected to the inner side of the fixed frame. Symmetrically arranged limiting holes are opened at the top of the fixed frame and support rods. Limiting rods are provided inside the limiting holes. Seedling trays are fixedly connected to the top of the limiting rods. A connecting plate is fixedly connected to the rear side of the fixed frame. Symmetrically arranged support blocks are fixedly connected to the top of the connecting plate. A rotating shaft is rotatably connected between two support blocks. Symmetrically arranged support arms are fixedly connected to the outer side of the rotating shaft. A fixed rod is fixedly connected to the end of the support arm away from the rotating shaft. A fixed frame is fixedly connected to both ends of the two fixed rods. A limiting groove is opened on the inner side of the fixed frame. A support plate located inside the fixed frame is slidably connected to the inner side of the limiting groove. A plurality of adjusting holes are opened at the top of the supporting plate. Bolt adjusting rods are threaded into the adjusting holes.

[0007] Preferably, there are eight limiting holes, and the limiting holes are arranged in groups of four, with a total of two groups. One group of limiting holes is symmetrically arranged on the surfaces of the two support rods, and the other group of limiting holes is symmetrically arranged at the four corners of the fixing frame.

[0008] Preferably, the size of the acupuncture tray is in two sets, one set of the acupuncture tray is set at the top of the two support rods, and the other set of the acupuncture tray is set at the top of the fixing frame.

[0009] Preferably, the inner dimensions of the fixing frame match the outer dimensions of the support plate, and the inner shape of the fixing frame matches the outer shape of the support plate, both being cuboids.

[0010] Preferably, there are three support legs, which are arranged in a triangular shape at the bottom of the fixed frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, through the setting of seedling trays, fixed frames, limiting grooves, support plates, adjusting holes, and bolt adjusting rods, the support plate, guided by the fixed frame and limiting grooves, simultaneously drills holes in the soil in the seedling trays through the bolt adjusting rods. By rotating the bolt adjusting rods, each bolt adjusting rod can be adjusted independently to adapt to the depth required by different seeds. This solves the problems of existing seedling drilling, which relies on hand-held drilling sticks to operate one hole at a time, resulting in low efficiency (average 0.5 seconds / hole), high labor intensity, and depth error of ±3cm. Most drilling machines on the market adopt a fixed depth design, which cannot adapt to the needs of different crop seeds (such as tomatoes requiring 3cm and peppers requiring 2.5cm).

[0013] 2. In this utility model, by using components such as a fixing frame, support rod, limiting hole, limiting rod, and acupuncture plate, and by using two types of acupuncture plates, the limiting holes on the fixing frame and support rod can respectively limit and fix acupuncture plates with 128 acupuncture points and 200 acupuncture points, greatly improving compatibility.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A seedling tray puncher includes a fixed frame 1 and support legs 2. The support legs 2 are fixedly connected to the bottom end of the fixed frame 1. Symmetrically arranged support rods 3 are fixedly connected to the inner side of the fixed frame 1. The top ends of the fixed frame 1 and the support rods 3 are provided with symmetrically arranged limiting holes 4. Limiting rods 5 are provided inside the limiting holes 4. A seedling tray 6 is fixedly connected to the top end of the limiting rods 5. A connecting plate 7 is fixedly connected to the rear side of the fixed frame 1. Symmetrically arranged support blocks 8 are fixedly connected to the top end of the connecting plate 7. The two support blocks 8 are rotatably connected. There is a rotating shaft 9, and a symmetrically arranged support arm 10 is fixedly connected to the outer side of the rotating shaft 9. A fixed rod 11 is fixedly connected to the end of the support arm 10 away from the rotating shaft 9. A fixed frame 12 is fixedly connected to both ends of the two fixed rods 11. A limiting groove 13 is symmetrically arranged on the inner side of the fixed frame 12. A support plate 14 located inside the fixed frame 12 is slidably connected to the inner side of the limiting groove 13. A number of adjustment holes 15 are opened at the top of the support plate 14. Bolt adjustment rods 16 are threadedly connected inside the adjustment holes 15.

[0024] There are eight limiting holes 4, arranged in two groups of four. One group of limiting holes 4 is symmetrically arranged on the surfaces of the two support rods 3, and the other group is symmetrically arranged at the four corners of the fixing frame 1. Different types of seedling trays 6 can be fixed by using the multiple limiting holes 4. There are two sets of seedling trays 6, one set at the top of the two support rods 3 and the other set at the top of the fixing frame 1, which can meet the needs of seedling cultivation of different numbers of plants. The inner dimensions of the fixing frame 12 match the outer dimensions of the support plate 14, and the inner shape of the fixing frame 12 matches the outer shape of the support plate 14, both being cuboids, which can more stably drive the bolt adjusting rod 16 to press down vertically. There are three support legs 2, which are triangularly arranged at the bottom of the fixing frame 1.

[0025] Workflow: When a seedling tray puncher is needed, first insert the seedling tray 6 with the required number of holes into the corresponding limiting hole 4 under the action of the limiting rod 5. Then, according to the depth required for planting, rotate the bolt adjusting rod 16 in the adjusting hole 15 to adjust the length of the bolt adjusting rod 16 below the support plate 14 to a suitable length. Then, with the support of the connecting plate 7, support block 8, rotating shaft 9 and support arm 10, flip the fixing frame 12 so that the fixing frame 12 covers the top of the seedling tray 6. Then, guided by the limiting groove 13, press down on the support plate 14. The support plate 14 drives the bolt adjusting rod 16 to be inserted into the hole of the seedling tray 6, punching holes in all the holes at the same time.
