Description

Technical Field

[0001] This utility model belongs to the field of planting equipment technology, specifically relating to a seed tray for small-grain vegetable seeds. Background Technology

[0002] Seedling trays involve filling plastic seedling trays with nutrient soil, then applying pressure through a conical protrusion to create holes, and finally inserting seeds into the holes. Currently, to experiment with the optimal hole depth for each batch of seedling trays, it is usually necessary to create multiple rows of holes in a stepped arrangement. Therefore, traditional seedling trays have the following problems: they cannot create multiple rows of stepped holes in the tray, and when conducting multi-depth seeding experiments on the same tray, holes must be created row by row, making operation less convenient. Utility Model Content

[0003] This invention provides a seed tray for small-grain vegetable seeds to solve the problems mentioned in the background art.

[0004] This utility model provides the following technical solution: a seed tray for small-grained vegetables, comprising a tray base, a pressing plate, and seed heads. The number of seed heads is several, arranged in three rows horizontally. Adjacent seed heads are fixedly connected by connecting segments. A one-way seed guide seat is slidably connected to the top of the pressing plate. A seed column selection component is provided at one end of the seed head near the one-way seed guide seat. The seed column selection component is slidably connected to the one-way seed guide seat. A longitudinal extension adjustment component is fixedly connected at one end of the seed head away from the seed column selection component. The longitudinal extension adjustment component is fixedly connected to the bottom end of the seed column selection component.

[0005] The point-seed selection component includes a shrink sleeve and a single-end extension seat. The shrink sleeve and the single-end extension seat are slidably connected. One end of the single-end extension seat extends to the inner side of the unidirectional point-seed guide seat, and the single-end extension seat is engaged with the unidirectional point-seed guide seat. The longitudinal extension adjustment component includes a hollow C-shaped buckle and a positioning protrusion. The positioning protrusion is fixedly connected to the inner side of the pressure plate platform. The hollow C-shaped buckle passes through the positioning protrusion and is engaged with the pressure plate platform.

[0006] The unidirectional point guide seat has several positioning connection holes, and one end of the shrink sleeve is fixedly connected to a connection protrusion that matches the shape of the positioning connection hole. The connection protrusion engages with the positioning connection hole.

[0007] The unidirectional seeding guide seat has a bidirectional transmission screw inside, which passes through the unidirectional seeding guide seat and is threadedly connected to it. An operating handle is fixedly connected to the top of the bidirectional transmission screw.

[0008] The hollow shaped buckle is fixedly connected to the bottom of the shrink sleeve, and the hollow shaped buckle is used to adjust the opening depth of the seeding head.

[0009] The base of the disc has several seed holes, and the seed-applying head is engaged with the seed holes.

[0010] The hollow shaped buckle has several slotted buckle seats that are evenly spaced, and the slotted buckle seats are engaged with the positioning buckle protrusions.

[0011] The beneficial effects of this utility model are as follows: When opening the holes in a stepped manner, pressing releases the locking and limiting between the hollow convex buckle and the positioning protrusion. Then, sliding the hollow convex buckle causes the seeding head to change its longitudinal distance according to the depth of the hole opening, thereby changing the extension length of the seeding head. This results in a stepped distribution of the tapered ends of the three rows of seeding heads. Next, the single-end extension seat at the head of the seeding head slides inward towards the unidirectional seeding guide seat, aligning the connecting protrusion at the head of the single-end extension seat with the positioning connection hole. The threaded action of the bidirectional transmission screw, achieved by rotating the handle, causes the unidirectional seeding guide seat to slide downward, allowing the single-end extension seat to... During the sliding process, the seeding guide seat applies pressure to the seeding head. At this time, the seeding head is pressed against the inside of the seeding hole opened on the base of the disc. Then, the remaining two rows of holes are opened to different depths in sequence, thus forming a stepped distribution of seeding holes. After the positioning connection hole and the connecting protrusion are engaged, the unidirectional seeding guide seat applies pressure to the seeding head and limits the sliding distance, so that the maximum opening depth of the seeding head is stable. Compared with the manual pressing method, this method can ensure that the opening depth meets the expected maximum value, avoid the uneven opening depth caused by uneven manual pressure, and thus ensure the accuracy of subsequent experiments.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] Please see Figures 1-4 This utility model provides the following technical solution: a seed tray for small-grained vegetables, including a tray base 1, a pressing plate 2, and seed heads 3. The number of seed heads 3 is several, and they are arranged in three rows horizontally. Adjacent seed heads 3 are fixedly connected by connecting segments 31. A one-way seed guide seat 5 is slidably connected to the top of the pressing plate 2. A seed column selection component 4 is provided at one end of the seed head 3 near the one-way seed guide seat 5. The seed column selection component 4 is slidably connected to the one-way seed guide seat 5. A longitudinal extension adjustment component 7 is fixedly connected to the one end of the seed head 3 away from the seed column selection component 4. A longitudinal extension adjustment component 7 is fixedly connected to the bottom end of the seed column selection component 4.

[0019] In this embodiment, the traditional seed tray applicator cannot open multiple rows of seed holes in a stepped distribution. This utility model solves this technical problem by setting up a seed selection component 4, a unidirectional seed guide seat 5, a bidirectional transmission screw 6, and a longitudinal extension adjustment component 7.

[0020] In this embodiment, the seed selection component 4 includes a shrink sleeve 41 and a single-end extension seat 42. The shrink sleeve 41 and the single-end extension seat 42 are slidably connected. One end of the single-end extension seat 42 extends to the inner side of the unidirectional seed guide seat 5, and the single-end extension seat 42 is engaged with the unidirectional seed guide seat 5. The longitudinal extension adjustment component 7 includes a hollow C-shaped buckle 71 and a positioning protrusion 72. The positioning protrusion 72 is fixedly connected to the inner side of the pressure plate 2. The hollow C-shaped buckle 71 passes through the positioning protrusion 72 and is engaged with the pressure plate 2.

[0021] In this embodiment, the one-way point seed guide seat 5 is provided with a plurality of positioning connection holes 51, and one end of the shrink sleeve 41 is fixedly connected with a connection protrusion 43 that matches the shape of the positioning connection hole 51, and the connection protrusion 43 engages with the positioning connection hole 51.

[0022] In this embodiment, when creating a stepped hole, the single-end extension seat 42 at the head of the seeder head 3 is slid inward toward the unidirectional seeding guide seat 5, so that the connecting protrusion 43 at the head of the single-end extension seat 42 corresponds to the position of the positioning connection hole 51. The unidirectional seeding guide seat 5 slides downward by rotating the bidirectional transmission screw 6 through the handle 61, so that the unidirectional seeding guide seat 5 applies pressure to the seeder head 3 during the sliding process, thereby completing the hole opening. At the same time, compared with the manual pressing method, it is easier to complete the hole pressing in hard soil.

[0023] In this embodiment, a bidirectional transmission screw 6 is provided inside the unidirectional seeding guide seat 5. The bidirectional transmission screw 6 passes through the unidirectional seeding guide seat 5 and is threadedly connected to the unidirectional seeding guide seat 5. An operating handle 61 is fixedly connected to the top of the bidirectional transmission screw 6.

[0024] In this embodiment, the unidirectional seeding guide seat 5 has a threaded groove adapted to the bidirectional transmission screw 6. A sliding rod is fixedly connected to the bottom of the unidirectional seeding guide seat 5. The sliding rod passes through the pressure plate platform 2 and is slidably connected to the pressure plate platform 2. The sliding rod realizes the sliding guidance of the unidirectional seeding guide seat 5, so that when the bidirectional transmission screw 6 is turned by the operating handle 61, the thread action of the bidirectional transmission screw 6 drives the unidirectional seeding guide seat 5 to achieve longitudinal adjustment.

[0025] In this embodiment, the hollow shaped buckle 71 has several slotted buckle seats 73 that are evenly spaced, and the slotted buckle seats 73 are engaged with the positioning buckle protrusions 72.

[0026] In this embodiment, the hollow fang-shaped buckle 71 is fixedly connected to the bottom of the shrink sleeve 41, and the hollow fang-shaped buckle 71 is used to adjust the opening depth of the seeding head 3.

[0027] In this embodiment, when the hollow fang-shaped buckle 71 is pinched inward along the bottom, the bottom spacing of the hollow fang-shaped buckle 71 decreases. At this time, the hollow fang-shaped buckle 71 can be slid along the inner side of the positioning protrusion 72 until the required adjustment depth of the seeding head 3 is reached. Then, the pressure on the hollow fang-shaped buckle 71 is released, and the hollow fang-shaped buckle 71 is reset. After that, it is repositioned by engaging with the positioning protrusion 72 through the multi-groove buckle seat 73. This ensures the convenience of adjusting the pressing depth of the seeding head 3. At the same time, the engagement and limiting of the positioning protrusion 72 and the multi-groove buckle seat 73 can prevent the seeding head 3 from sliding displacement when pressing the acupoint.

[0028] In this embodiment, the base 1 of the disc body is provided with a plurality of seed holes 11, and the seed applicator head 3 is engaged with the seed holes 11; wherein, the seed holes 11 are used to reserve opening positions so that when the seed applicator head 3 is inserted into the inside of the base 1 of the disc body, the holes can be quickly formed.

[0029] The working principle and usage process of this utility model are as follows: When opening the holes in a stepped manner, first press to release the locking and limiting between the hollow convex buckle 71 and the positioning protrusion 72. Then, slide the hollow convex buckle 71 to change the longitudinal distance of the seeding head 3 according to the depth of the hole opening, thereby changing the extension length of the seeding head 3, so that the bottom conical ends of the three rows of seeding heads 3 are distributed in a stepped manner. Then, slide the single-end extension seat 42 at the head end of the seeding head 3 inward to the unidirectional seeding guide seat 5, so that the connecting protrusion 43 at the head end of the single-end extension seat 42 is connected to the positioning connection. After completing the above operations, the pressure plate 2 is placed on the upper end of the base 1 of the disc body, and the unidirectional seeding guide seat 5 slides downward by rotating the two-way transmission screw 6 through the handle 61. During the sliding process, the unidirectional seeding guide seat 5 applies pressure to the seeding head 3. At this time, the seeding head 3 presses against the inside of the seeding hole 11 opened on the base 1 of the disc body. Then, the remaining two rows of holes are opened in sequence with adjusted depths to form a stepped distribution of seeding holes. After that, the pressure plate 2 is removed from the top of the base 1 of the disc body.
