Description

Technical Field

[0001] This utility model belongs to the field of planting technology, specifically relating to a seeder for microparticle seeds. Background Technology

[0002] In nature, some plants have small seeds; for example, the seeds of *Gnaphalium affine* are about 600 μm in length. Achieving uniform planting with these micro-seeds is challenging. Traditional sowing methods typically involve mixing the micro-seeds with soil or sand and then broadcasting them. However, this method has several drawbacks: seeds and carrier material are difficult to distinguish, leading to uneven sowing; sowing density is difficult to control; seed resources are wasted; and subsequent field management is affected.

[0003] Currently, there is a lack of specialized seeding tools for this type of micro-seed on the market. Therefore, it is necessary to design a micro-seed seed planter. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this solution provides a micro-seed planter.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A micro-seed planter includes a rod, a planting trough, and a seed box. The planting trough is an elongated trough structure and is fixed to the upper part of the rod. Multiple planting holes are provided at the bottom of the planting trough, and a first screen covers the inner bottom surface of the planting trough. The seed box is slidably disposed in the planting trough, and a second screen is provided at the opening at the bottom of the seed box. Micro-seeds are loaded into the seed box. When the mesh openings of the first and second screens are aligned, the micro-seeds pass through the first and second screens and fall to the ground. When the mesh openings of the first and second screens are misaligned, the micro-seeds are blocked by the first and second screens.

[0007] As an alternative or supplement to the above structure, a ring is provided on the outer facade of the seed box, and the ring is fitted onto the insertion rod; the seed box can be fixed to different positions on the insertion rod by the ring.

[0008] As an alternative or supplement to the above structure: a joint is provided on one side of the ring clamp, and a fastening screw is provided at the joint. The fastening screw is used to adjust the size of the gap of the joint so that the ring clamp tightens or loosens the insert rod.

[0009] As an alternative or supplement to the above structure: the upper end of the insertion rod is vertically connected to a transverse fulcrum, and the transverse fulcrum is connected to a handle by a screw; when the screw is loosened, the handle can rotate with the screw as the fulcrum.

[0010] As an alternative or supplement to the above structure: the seeding trough includes a base plate and a frame; the seeding hole is disposed on the base plate; the frame is fixedly connected to the base plate and cooperates to clamp the edge of the first screen.

[0011] As an alternative or supplement to the above structure: the number of seeding holes is 3 to 6, and they are arranged in a row.

[0012] As an alternative or supplement to the above structure: the seed box includes a box shell and a frame; the second screen covers the bottom of the box shell, the frame is fitted over the box shell, and the edge of the second screen is clamped between the frame and the box shell.

[0013] The beneficial effects of this utility model are as follows: This solution uses the mutual movement of two first screens to make the mesh openings alternately staggered and aligned, thereby enabling the micro-seeds to be evenly spread, achieving uniform sowing, facilitating the control of sowing density, saving seed resources, and facilitating subsequent field management.

[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0022] like Figures 1 to 4As shown, this embodiment designs a micro-seed planter, including components such as a rod 1, a seeding trough 2, and a seed box 3.

[0023] The upper end of the insertion rod 1 has an anti-slip sleeve, and the lower end has a pointed tip, so as to facilitate insertion into the ground and achieve positioning.

[0024] The seeding trough 2 is a long trough structure and is fixed to the upper part of the insertion rod 1. A ring 5 is provided on the outer side of the seed box 3, and the ring 5 is fitted onto the insertion rod 1. The seed box 3 can be fixed to different positions on the insertion rod 1 by the ring 5. A seam is provided on one side of the ring 5, and a fastening screw is provided at this seam. The fastening screw is used to adjust the size of the seam gap, so that the ring 5 tightens or loosens the insertion rod 1. When the fastening screw is loosened, the ring 5 loosens the insertion rod 1, allowing the position of the seeding trough 2 to be adjusted along the height of the insertion rod 1. After the height and position are adjusted, the fastening screw can be tightened again to fix the position of the seed box 3.

[0025] The sowing trough 2 includes components such as a base plate 21, a first screen 22, and a frame 23; multiple sowing holes are provided at the bottom of the sowing trough 2, the sowing holes being round or square holes provided on the base plate 21, the number of sowing holes being 3 to 6, and arranged in a row; the first screen 22 is covered on the inner bottom surface of the sowing trough 2; the frame 23 is fixedly connected to the base plate 21 and cooperates to clamp the edge of the first screen 22.

[0026] The seed box 3 is set inside the sowing trough 2 and can slide along the length of the sowing trough 2. The seed box 3 includes components such as a box shell 31, a second screen 32, and a frame 33; the second screen 32 is provided at the opening at the bottom of the seed box 3. Specifically, the second screen 32 covers the bottom of the box shell 31, the frame 33 is fitted over the box shell 31, and the edge of the second screen 32 is clamped between the frame 33 and the box shell 31.

[0027] The upper end of the insertion rod 1 is vertically connected to a transverse fulcrum 11, and the transverse fulcrum 11 is connected to a handle 4 by a screw; when the screw is loosened, the handle 4 can rotate with the screw as the fulcrum, and when the screw is tightened, the handle 4 can be perpendicular to the insertion rod 1, thus facilitating operation.

[0028] When using the micro-seed planter in this embodiment:

[0029] The micro-seeds are placed in the seed box 3. The worker holds the handle 4 in one hand and the upper end of the insertion rod 1 in the other, inserting the lower end of the insertion rod 1 into the soil. Then, the seed box 3 is controlled to slide back and forth in the sowing trough 2. When the mesh openings of the first screen 22 and the second screen 32 are aligned, the micro-seeds can pass through the first screen 22 and the second screen 32 and fall to the ground, achieving planting. When the mesh openings of the first screen 22 and the second screen 32 are misaligned, the micro-seeds are blocked by the first screen 22 and the second screen 32, thus preventing excessive seed falling. After changing the sowing position, the above operation is repeated to achieve uniform sowing.

[0030] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
