Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and in particular to a handheld seeder. Background Technology

[0002] Rapeseed is an important oilseed crop in my country. Improving the planting efficiency of rapeseed is crucial to ensuring national oilseed security. At present, most seeding machinery is designed to adapt to grains and beans with larger particle sizes, which is difficult to meet the small particle characteristics of rapeseed (the particle size is usually 1-2 mm).

[0003] In actual sowing, traditional mechanical equipment has the following problems: rapeseed has a smooth surface and high fluidity, making it easy to scatter during the sowing process; due to the light weight of the seeds, they are affected by wind and are difficult to fall accurately into the predetermined position; the holes of the seed metering device are too large, which may cause multiple seeds to be discharged at the same time; small seeds are easy to get stuck in the gaps of the machinery, causing equipment blockage.

[0004] To address these issues, farmers often resort to manual planting to dig holes and sow seeds. While this traditional method ensures relatively uniform seed distribution, it is labor-intensive and inefficient. Therefore, there is an urgent need to design a handheld planter to assist manual planting. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where mechanical equipment is difficult to meet the small particle characteristics of rapeseed and where manual digging and sowing are intensive, and to propose a handheld seeder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A handheld seeder includes a detachably connected upper cylinder and a lower cylinder, which form a cavity. The bottom of the lower cylinder is provided with a feeding port. A movable rod is slidably arranged in the cavity. A seeding groove is opened on the movable rod and communicates with the cavity to hold a preset number of seeds. When the seeding groove extends out of the feeding port, the seeds in the seeding groove are sown.

[0008] To facilitate the guidance of rapeseed seeds, preferably, a first inclined surface is provided on the outer wall of the movable rod, the first inclined surface is coupled to the top of the sowing trough, and the first inclined surface extends into the sowing trough.

[0009] To facilitate the guidance and feeding of rapeseed seeds, a second inclined surface is further provided on the outer wall of the movable rod, which is coupled to the bottom of the sowing trough.

[0010] To improve the guiding effect of rapeseed seeds, preferably, the inclination angles of the first and second inclined surfaces are both in the range of 30°-60°.

[0011] Furthermore, the tilt angle of the first inclined surface is 45°.

[0012] To improve the sowing efficiency of rapeseed seeds, preferably, the first inclined surface and the second inclined surface are arc-shaped transition surfaces or inclined planes.

[0013] To facilitate the containment of rapeseed seeds, the cross-section of the sowing trough is preferably a V-shaped trough or a U-shaped trough.

[0014] To facilitate soil breaking, preferably, the bottom of the movable rod is fixedly connected to a soil breaking structure, which is a conical rotating body.

[0015] To facilitate the detachable connection of the upper and lower cylinders, preferably, a first contact surface is provided on the inner wall of the upper cylinder, and a second contact surface is provided on the inner wall of the lower cylinder. Both the first and second contact surfaces are cylindrical surfaces. When the upper and lower cylinders are connected, the first contact surface is fitted onto the second contact surface.

[0016] To facilitate the connection of the movable rod, preferably, a disc is fixedly connected to the top of the upper cylinder, and a through hole is opened on the disc, with the axis of the through hole coinciding with the axis of the feed port, and the movable rod passes through the through hole.

[0017] To facilitate the reset of the movable rod, preferably, a button is fixedly connected to the top of the movable rod, and a limiting spring is sleeved on the movable rod, with the two ends of the limiting spring connected to the button and the disc respectively.

[0018] Compared with the prior art, the present invention provides a handheld seeder with the following advantages:

[0019] 1. This handheld seeder allows rapeseed seeds inside the cylinder to be quickly sown through the seeding trough by pressing the position of the movable rod, thereby assisting workers in sowing, reducing their labor intensity and improving work efficiency.

[0020] 2. This handheld planter, with its V-shaped or U-shaped planting trough, can hold 1-6 rapeseed seeds, ensuring a relatively stable number of rapeseed seeds in the trough each time it is planted.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technology. This utility model can press the position of the movable rod to make the rapeseed seeds in the cavity of the cylinder quickly sown through the sowing trough, thereby assisting workers in sowing, reducing their labor intensity and improving work efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Example:

[0032] Reference Figures 1-6A handheld planter includes a detachably connected upper cylinder 1 and a lower cylinder 5, which form a cavity for storing rapeseed seeds. Both cylinders are made of transparent plastic, allowing for more direct observation of the stored seeds. Rapeseed seeds can be loaded into the cavity formed by the upper cylinder 1 and the lower cylinder 5. To facilitate convenient seed storage, a first contact surface 3 is provided on the inner wall of the upper cylinder 1, and a second contact surface 6 is provided on the inner wall of the lower cylinder 5. The first contact surface 3 and the second contact surface 6 are in contact with each other.

[0033] Reference Figure 3 and Figure 4 A first contact surface 3 is provided on the inner wall of the upper cylinder 1, and a second contact surface 6 is provided on the inner wall of the lower cylinder 5. Both the first contact surface 3 and the second contact surface 6 are cylindrical surfaces. When the upper cylinder 1 and the lower cylinder 5 are connected, the first contact surface 3 is fitted onto the second contact surface 6. The wall thickness of the upper cylinder 1 and the lower cylinder 5 ranges from 1mm to 5mm. The wall thickness used in this device is 3mm. The thickness of the first contact surface 3 on the upper cylinder 1 is 1.5mm, and the thickness of the second contact surface 6 on the lower cylinder 5 is 1.5mm. When the upper cylinder 1 and the lower cylinder 5 are engaged with each other, the second contact surface 6 can fit against the first contact surface 3, thereby forming a locking and engaging effect.

[0034] A discharge port 7 is provided at the bottom of the lower cylinder 5, and a disc 2 is fixedly connected to the top of the upper cylinder 1. A through hole 4 is provided on the disc 2, and the axis of the through hole 4 coincides with the axis of the discharge port 7. The diameters of the through hole 4 and the discharge port 7 are the same. A movable rod 8 is slidably connected to the through hole 4, and a soil-breaking structure 12 is provided at the bottom of the movable rod 8. The diameter of the movable rod 8 is smaller than the diameters of the through hole 4 and the discharge port 7. In this device, the diameters of the through hole 4 and the discharge port 7 are 8mm, while the diameter of the movable rod 8 can be 7.8mm. This allows the movable rod 8 to be slidably connected to the through hole 4 and also prevents the rapeseed from leaking out of the discharge port 7.

[0035] Additionally, a sowing trough 10 is provided on the movable rod 8. The sowing trough 10 is connected to the cavity and is used to hold a preset number of seeds, usually 1-6 seeds. When the sowing trough 10 extends to the discharge port 7, the seeds in the sowing trough 10 are sown. A first inclined surface 9 is provided on the outer wall of the movable rod 8, and the inclined surface of the first inclined surface 9 extends towards the groove of the sowing trough 10. The first inclined surface 9 and the sowing trough 10 are rounded. The cross-section of the sowing trough 10 is a V-shaped groove or a U-shaped groove. The volume of the groove can hold 1-6 rapeseed seeds. A second inclined surface 11 is provided on the outer wall of the movable rod 8, and the second inclined surface 11 is coupled to the bottom of the sowing trough 10. The second inclined surface 11 is an arc-shaped transition surface or an inclined plane, which allows the rapeseed seeds to be discharged quickly.

[0036] The bottom of the movable rod 8 is fixedly connected to the soil breaking structure 12, which is used to insert into the soil or guide the discharge. The lower edge of the second inclined surface 11 and the upper edge of the soil breaking structure 12 form a gap. When it is not necessary to sow rapeseed seeds, the gap formed between the lower edge of the second inclined surface 11 and the upper edge of the soil breaking structure 12 will block the discharge port 7, thereby preventing rapeseed seeds from leaking. The rapeseed seeds can be guided into the sowing trough 10 through the first inclined surface 9.

[0037] To improve the guiding effect of the first inclined surface 9, the inclination angle of the first inclined surface 9 is in the range of 30°-60°. In this device, the inclination angle of the first inclined surface 9 is 45°, which can maximize the guiding effect of rapeseed.

[0038] To facilitate pressing and moving the movable rod 8, a button 13 is fixedly connected to the top of the movable rod 8. A limiting spring 14 is sleeved on the movable rod 8, and the two ends of the limiting spring 14 are respectively connected to the button 13 and the disc 2. When it is necessary to sow rapeseed seeds, the outer wall of the upper cylinder 1 and the lower cylinder 5 can be held by hand, and then the button 13 can be pressed with the fingers. The distance between the disc 2 and the button 13 is 30mm, the length of the sowing trough 10 is 30mm, and the axial gap between the lower edge of the second inclined surface 11 and the upper edge of the soil breaking structure 12 is 2mm. When the movable rod 8 descends, the rapeseed seeds contained in the sowing trough 10 can be discharged along the second inclined surface 11. During this process, the limiting spring 14 is compressed. When sowing is completed, the button 13 is stopped from being pressed. At this time, the limiting spring 14 expands, the movable rod 8 resets and seals the discharge port 7, which can assist workers in sowing, reduce their labor intensity and improve work efficiency.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
