Abstract
Description
Technical Field
[0001] The invention belongs to the field of planting equipment, and in particular relates to a handheld seeder. Background Art
[0002] When planting seeds in the field, a seeder is usually needed. However, most of the prior art seeders are complex in structure, heavy in weight, and need to be driven by tractors and other agricultural machinery, which have poor flexibility. For some small fields to be sown, or in some mountainous areas or sloping fields with uneven ground, or in fields where some seeds have not sprouted due to various reasons after sowing, a seeder cannot be used for sowing. In addition, the price of large seeders is usually high, and the purchase cost is high for small-scale farmers or farmers with limited economic conditions. For small-scale farmers, manual sowing is time-consuming and labor-intensive, and the sowing efficiency is low, which is not convenient for production. Summary of the invention
[0003] The present invention is intended to provide a handheld seeder to solve the problem that the seeder cannot be flexibly used in small-scale or irregular fields, resulting in low sowing efficiency.
[0004] A handheld seeder in the present scheme includes a planting tube and a seed groove, wherein the planting tube is a cylinder penetrating from top to bottom, and is fixedly connected to a base plate near the bottom of the planting tube, a circular hole is provided in the center of the base plate, and the seed groove is located in the lower middle part of the planting tube, a through hole is provided at the bottom of the seed groove, a plug is provided inside the through hole, the plug can completely block the through hole, and the plug can only extend to one side of the base plate, an end of the plug away from the base plate is fixedly connected to a connecting rod, and the other end of the connecting rod extends out of the planting tube, and a reset mechanism is provided, and the reset mechanism is fixedly connected to the planting tube.
[0005] The working principle of this scheme is as follows: when in use, seeds are put into the seed slot, and then the planting tube is inserted into the soil to be planted. The planting tube piles the soil into a cylindrical soil block, and then the reset mechanism is pressed to drive the connecting rod to descend, thereby causing the plug to descend. The plug pokes a small hole above the cylindrical soil block, and the seeds in the seed slot, during the process of the plug descending, open the through hole at the bottom of the seed slot, and the seeds can fall from the through hole into the soil block below to complete the planting. At this time, the reset mechanism is released, and the reset mechanism can drive the connecting rod and the plug at the bottom of the connecting rod to rise, blocking the through hole of the seed slot to prevent the seeds from continuing to leak;
[0006] Beneficial effects: 1. The handheld seeder is small in size and low in cost, which is more suitable for small-scale farmers or farmers with limited economic conditions, and can effectively improve the planting efficiency of farmers;
[0007] 2. The soil blocks formed by the handheld seeder after planting are cylindrical. The cylindrical soil blocks are convenient for later transplanting and centralized management, making the planting area clearer;
[0008] 3. The handheld seeder can adapt to various terrains and can be used in various areas to be sown. It has high flexibility and is simple to operate and easy to use.
[0009] Furthermore, the reset mechanism includes a button box and a button, the button box is fixedly connected to the planting tube, the button is slidably connected to the button box, and one end of the button extends out of the button box, the end of the connecting rod away from the plug extends into the interior of the button box and is fixedly connected to the button, and the end of the connecting rod located inside the button box is wrapped with a reset spring, one end of the reset spring is fixedly connected to the inner bottom of the button box, and the other end is fixedly connected to the inner bottom of the button. When in use, pressing the button can drive the connecting rod and the plug fixedly connected at the end to descend together, poke a hole in the soil block, and make the seeds fall down. After the planting is completed, the button is released, and the reset spring can drive the connecting rod and the plug to rise together to block the through hole at the bottom of the seed groove.
[0010] Furthermore, a plurality of support rods are provided between the button box and the planting tube, one end of the support rod is fixedly connected to the planting tube, and the other end is fixedly connected to the button box. The support rods support the button box without affecting the addition of seeds.
[0011] Furthermore, a spring is fixedly connected to one end of the bottom plate away from the seed slot, a through hole is located in the spring, a push plate is fixedly connected to one end of the spring away from the bottom plate, the push plate is slidably connected to the planting tube, and a through hole of the same size as the bottom plate is opened in the center of the push plate. When in use, the planting tube is pressed downward to press the soil below into the planting tube. During the descent process, the soil can push the push plate upward. After the planting is completed, the planting tube is lifted, and the spring can push the push plate downward to prevent the soil from remaining in the planting tube, and the through hole in the center does not affect the descent of the plug and the planting of seeds.
[0012] Furthermore, a guide plate is disposed around one end of the seed groove near the base plate, one end of the guide plate is fixed to the seed groove, and the other end is inclined toward the through hole of the base plate and extends into the through hole. The guide plate is hollow inside, and the end extending into the through hole is connected to the outside, and the size of the connection is similar to that of a plug.
[0013] When the plug descends, the plug first enters the guide plate, and then enters the connection between the guide plate and the outside to block the connection. At this time, the plug descends to the bottom to poke a small hole in the top of the soil block, and when the plug descends, the seeds in the seed groove fall into the guide plate along the through hole. After the plug is restored, the through hole at the bottom of the seed groove is blocked, and the connection between the guide plate and the outside is released. At this time, the seeds in the guide plate will fall into the small holes poked below. The guide plate can fix the number of seeds falling out of the seed groove each time, and can guide the seeds into the small holes above the soil block.
[0014] Furthermore, handles are fixedly connected to the two opposite sides of the button box, so that the operator can operate the button by hand. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A through hole is provided at the bottom of the seed groove 11, and a plug 10 is provided in the through hole. The maximum diameter of the plug 10 is consistent with that of the through hole. A connecting rod 12 is fixedly connected to the upper end of the plug 10. One end of the connecting rod 12 extends out of the planting tube 1. Four connecting columns 3 are fixedly connected to the top of the planting tube 1. The top of the connecting column 3 is fixedly connected to a button box 5. A button 4 is slidably connected in the button box 5. One end of the connecting rod 12 extending out of the planting tube 1 extends into the button box 5 and is slidably connected to the button box 5. The top of the connecting rod 12 is fixedly connected to the button 4. A return spring 14 is wrapped around the outer side of the connecting rod 12. One end of the return spring 14 is fixedly connected to the inner bottom of the button 4, and the other end is fixedly connected to the inner bottom of the button box 5. Handles 6 are fixedly connected to the opposite sides of the button box 5.
[0023] A bottom plate 9 is provided below the seed groove 11, and the bottom plate 9 is fixedly connected to the planting tube 1. A through hole is opened in the center of the bottom plate 9, and the lower end of the guide plate 13 extends into the through hole. A spring 8 is fixedly connected to the bottom of the bottom plate 9, and the inner diameter of the spring 8 is larger than the diameter of the through hole. A push plate 7 is fixedly connected to the other end of the spring 8, and a through hole consistent with the through hole of the bottom plate 9 is opened in the center of the push plate 7.
[0024] The specific implementation process is as follows: when in use, the operator holds the handle 6, places the planting tube 1 vertically on the ground, and presses down to make the bottom of the planting tube 1 enter the soil. During the pressing process, the soil pushes the push plate 7 to extend the compression spring 8 upward. After the push is in place, the soil below becomes a cylindrical soil block, and then the button 4 can be pressed. The button 4 compresses the connecting rod 12 to descend, and the connecting rod 12 will bring the plug 10 down, so that the plug 10 enters the guide plate 13 and descends to the bottom of the guide plate 13, so that the plug 10 enters the through hole of the bottom plate 9 and the push plate 7, and the push plate 7 is lowered. The plug 10 pokes a small hole in the center of the soil block. At the same time, when the plug 10 descends, the through hole at the bottom of the seed slot 11 is opened, so that the seeds in the seed slot 11 fall into the guide plate 13. After the plug 10 pokes a hole in the soil, the button 4 is released, and the reset spring 14 drives the button 4 to reset, thereby driving the connecting rod 12 and the plug 10 to rise, so that the plug 10 re-enters the through hole at the bottom of the seed slot 11, and the bottom of the seed slot 11 is sealed. The seeds stored in the guide plate 13 will enter the small hole below under the guidance of the guide plate 13 after the plug 10 leaves.
[0025] After the planting is completed, the handle 6 is held to drive the planting tube 1 to rise. During the rising process, the spring 8 is reset to push the push plate 7 downward to prevent the soil from adhering to the planting tube 1 and causing the planting failure.
