[0028] Example 1: As Figure 1-5 As shown, this utility model provides a handheld agricultural seeder, including a handle 1, a storage mechanism 2 is provided on the bottom surface of the handle 1, a seeding mechanism 3 is provided inside the storage mechanism 2, and a switch mechanism 4 is provided at the output end of the seeding mechanism 3;

[0029] The seeding mechanism 3 includes a sleeve 31, which is slidably connected to the bottom surface of the handle 1. A feed window 32 is provided inside the top side of the sleeve 31. A baffle 37 is fixedly connected to the inner side of the sleeve 31. A collar 39 is fixedly connected to the bottom side of the baffle 37. An adjusting device 38 is rotatably connected inside the collar 39. The adjusting device 38 includes a connecting plate 381, which is rotatably connected inside the collar 39. The top surface of the connecting plate 381 penetrates the top surface of the collar 39 and is fixedly connected to a fixing rod 382. An adjusting plate 383 is fixedly connected to the side of the fixing rod 382. The adjusting plate 383 is movably connected to the side of the baffle 37.

[0030] A rotating rod 384 is fixedly connected to the top surface of the fixed rod 382. The rotating rod 384 is rotatably connected to the inside of the top surface of the sleeve 31. A fixing bolt 385 is movably connected to the inside of the top surface of the rotating rod 384. One end of the fixing bolt 385 passes through the bottom surface of the rotating rod 384 and is threaded to the top surface of the sleeve 31.

[0031] A limiting rod 33 is fixedly connected to the side of the sleeve 31. A fixing plate 36 is fixedly connected to the bottom surface of the limiting rod 33. The fixing plate 36 is fixedly connected to the bottom side of the sleeve 31. An adjusting nut 35 is threadedly connected to the middle of the outer surface of the sleeve 31. A spring 34 is fixedly connected to the top surface of the adjusting nut 35. One end of the spring 34 is fixedly connected to the bottom surface of the handle 1.

[0032] In this embodiment, the sleeve 31 is provided with a frustum at the top, which prevents the sleeve 31 from detaching from the inside of the storage mechanism 2. The inside of the sleeve 31 is a hollow cylinder. The baffle 37 is fixed inside the sleeve 31 and the sleeve 31 is close to the side of the feed window 32. The rotating rod 384 is provided inside the top surface of the sleeve 31 and, in cooperation with the connecting plate 381, fixes the fixing rod 382.

[0033] The sleeve 31 is subjected to a vertical upward compressive force. The sleeve 31 can be retracted into the storage mechanism 2 by the contraction of the spring 34. The seeds inside the storage mechanism 2 are scattered by the limit rod 33. The scattered seeds will enter the sleeve 31 from the opening end of the feed window 32. The stroke of the spring 34 can be controlled by adjusting the adjusting nut 35 to change the rebound force of the sleeve 31.

[0034] The fixing bolt 385 can be removed and the rotating rod 384 can be rotated. At this time, the fixing rod 382 will drive the connecting plate 381 to rotate inside the collar 39, so that the distance between the adjusting plate 383 and the baffle 37 can be adjusted. The approximate number of seeds that can enter the feed window 32 at one time can be controlled by controlling the distance between the adjusting plate 383 and the baffle 37.

[0035] Example 2: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the storage mechanism 2 includes a storage box 21, the storage box 21 is fixedly connected to the bottom surface of the handle 1, the sleeve 31 is slidably connected to the inside of the bottom surface of the storage box 21, and the limiting rod 33 is slidably connected to one end of the bottom surface of the storage box 21.

[0036] A hinge 22 is fixedly connected to the side of the storage box 21. A feeding door 23 is fixedly connected to the other end of the hinge 22. An observation window 24 is fixedly connected to the inside of the side of the feeding door 23. A threaded sleeve 25 is fixedly connected to the side of the feeding door 23. There are multiple threaded sleeves 25. Another threaded sleeve 25 is fixedly connected to the other side of the storage box 21. A threaded rod 26 is threadedly connected inside the threaded sleeve 25.

[0037] In this embodiment, by laying the storage box 21 horizontally flat and removing the threaded rod 26, the feeding door 23 can be opened with the hinge 22 as the axis to fill the storage box 21 with seeds. Since the storage box 21 is arc-shaped, even if the storage box 21 is filled, the internal space of the device can still allow the sleeve 31 and the limiting rod 33 to move inside. When the seeds are filled, the storage box 21 and the feeding door 23 can be locked by screwing the threaded rod 26 into the closed threaded sleeve 25.

[0038] Example 3: As Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the switching mechanism 4 includes a triangular plate 41, the triangular plate 41 is fixedly connected to the output end of the sleeve 31, the side of the triangular plate 41 is provided with a movable groove 42, the movable groove 42 is fixedly connected to a slide rod 43, and a return spring 44 is sleeved on the outer surface of the slide rod 43.

[0039] A slider 45 is slidably connected to the bottom of the outer surface of the slider 43. The slider 45 is slidably connected inside the movable groove 42. A side plate 46 is fixedly connected to the side of the slider 45. A contact rod 47 is fixedly connected to the side of the side plate 46.

[0040] In this embodiment, a feeding channel is provided on the top surface of the triangular plate 41 and extends through the entire triangular plate 41. When the user holds the device and pushes it towards the ground, the contact rod 47 will first contact the ground and drive the slider 45 and the slider 45 to slide along the sliding rod 43. At this time, the side plate 46 will leave the bottom opening of the triangular plate 41, so that the seeds inside the triangular plate 41 can fall to the desired position. Then, when the device is lifted, under the action of the return spring 44, the side plate 46 will cover the opening end of the triangular plate 41 again.

[0041] The working principle of this handheld agricultural seeder will be explained in detail below.

[0042] like Figure 1-5 As shown, by laying the storage box 21 horizontally flat and removing the threaded rod 26, the feeding door 23 can be opened with the hinge 22 as the axis to fill the storage box 21 with seeds. Since the storage box 21 is arc-shaped, even if the storage box 21 is filled, the internal space of the device can still allow the sleeve 31 and the limiting rod 33 to move inside. When the seeds are filled, the storage box 21 and the feeding door 23 can be locked by screwing the threaded rod 26 into the closed threaded sleeve 25.

[0043] When the user is standing, holding the handle 1, the switch mechanism 4 is aligned with the desired planting position and pushed out. The contact rod 47 will first touch the ground and drive the slider 45 and the slider 45 to slide along the slider 43. At this time, the side plate 46 will leave the bottom opening of the triangle plate 41.

[0044] At the same time, the sleeve 31 is subjected to a vertical upward squeezing force. The spring 34 can retract the sleeve 31 into the storage box 21. The limiting rod 33 disperses the seeds inside the storage mechanism 2. The scattered seeds will enter the sleeve 31 from the opening end of the feed window 32 and fall to the desired position through the bottom opening of the triangular plate 41. Then, the device is lifted. Under the action of the reset spring 44, the side plate 46 covers the opening end of the triangular plate 41 again. The spring 34 pushes the sleeve 31 out, so that the feed window 32 leaves the inside of the storage box 21, which is convenient for subsequent sowing.

[0045] The fixing bolt 385 can be removed and the rotating rod 384 can be rotated. At this time, the fixing rod 382 will drive the connecting plate 381 to rotate inside the collar 39, so that the distance between the adjusting plate 383 and the baffle 37 can be adjusted. The approximate number of seeds that can enter the feed window 32 at one time can be controlled by controlling the distance between the adjusting plate 383 and the baffle 37.

[0046] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
