[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0037] This application discloses a portable agricultural seeding device. (See also...) Figure 1 The portable agricultural seeding device includes a base 1, a seed storage box 2, a enclosure assembly 3, a seeding drive assembly 6, and a handle 5. The base 1 is a rounded rectangular hollow box, which can reduce the overall weight of the seeding device. The seed storage box 2 is a rectangular box with its opening facing upwards. The bottom of the seed storage box 2 is provided with a conical feeding hopper 21, and the bottom of the feeding hopper 21 is provided with a feeding pipe 22. The outlet of the feeding pipe 22 is the feeding port. The enclosure assembly 3 is located between the base 1 and the seed storage box 2, forming a seeding cavity that communicates with the feeding port. A seeding opening is provided on one side for seeds to pass through. The seeding drive assembly 6 is used to push the seeds out of the seeding cavity through the seeding opening. The handle 5 is cylindrical and is fixedly connected to the seed storage box 2 by a connecting rod. It is located on the side of the seed storage box 2 away from the enclosure assembly 3.

[0038] Before the staff uses the seeding device to seed, the seeds are poured into the seed storage box 2, and during seeding, the seeding device is held in the hand by the handle 5, the seeding opening is directed outward, the seeds are pushed out of the seeding opening by controlling the seeding drive assembly 6, and the seeds are walked along the seeding path, so that the seeds are seeded along the seeding path. The containment assembly 3 can limit the seeds from the seed storage box 2, so that the seeds can only be scattered along the seeding opening. The seeding drive assembly 6 pushes the seeds out of the seeding opening from the seeding cavity, thereby realizing directional seeding of the seeds, effectively reducing labor intensity, improving seeding efficiency, and the device is convenient to carry, and can adapt to small farmland, mountainous areas or orchards and other special environments, thereby improving the flexibility of the seeding efficiency.

[0039] Specifically, referring to Figure 1 and Figure 2 , the containment assembly 3 includes a layer plate 31, a fixed plate 32, and movable plates 33 arranged on both sides of the fixed plate 32. The layer plate 31 is a round rectangular plate with the same size and shape as the cross section of the base 1. The layer plate 31 is arranged between the base 1 and the seed storage box 2 in the transverse direction. A through hole is formed in the bottom plate, and the blanking pipe 22 is in communication with the through hole in the bottom plate. The top and bottom of the fixed plate 32 are fixedly connected to the layer plate 31 and the base 1 by bolts, respectively. Both movable plates 33 are round rectangular plates. One end of the movable plate 33 is close to the end of the fixed plate 32 without abutting against the fixed plate 32. This end is arc-shaped and is rotatably connected to the base 1. The other end is a movable end. The movable ends of the two movable plates 33 are the seeding opening. That is, the fixed plate 32 and the two movable plates 33 form a U-shaped containment, and together with the layer plate 31 and the base 1, a seeding cavity is formed. The opening side of the seeding cavity is the seeding opening. The layer plate 31 is provided with an adjusting assembly 4 for rotating the movable plate 33.

[0040] Referring to Figure 3 , the adjusting assembly 4 includes a first rotating shaft 41, an adjusting worm gear 42, an adjusting worm 43, and a hand wheel 44. The first rotating shaft 41 is the rotating shaft of the movable plate 33. One end of the first rotating shaft 41 is rotatably connected to the top of the base 1, and the other end protrudes through the layer plate 31. The adjusting worm gear 42 is coaxially fixedly connected to the end of the first rotating shaft 41 protruding through the layer plate 31 by a pin key connection. The adjusting worm 43 is arranged in the transverse direction. One end of the adjusting worm 43 is rotatably connected to the layer plate 31 by a rotating seat, and the other end is coaxially fixed with the hand wheel 44. The adjusting worm 43 is meshingly arranged with the adjusting worm gear. The hand wheel 44 protrudes from the layer plate 31 through the side of the layer plate 31, so as to facilitate the staff to rotate the hand wheel 44.

[0041] The hand wheel 44 is used to control the rotation of the worm gear to drive the first rotating shaft 41 to rotate, so that the angle of the two movable plates 33 changes to change the size of the sowing opening, thereby adjusting the sowing range. The transmission mode of the worm gear not only has the effect of output rotation, but also has the purpose of self-locking, so that the movable plate 33 with the adjusted angle can be maintained stable.

[0042] The sowing driving assembly 6 can be manually controlled or electrically controlled. In this embodiment, in order to save labor and improve the sowing efficiency, the sowing driving assembly 6 is electrically controlled.

[0043] Specifically, referring to Figure 4 , the sowing driving assembly 6 comprises a driving disc 61, a second rotating shaft 62, driving blades 63 and a driving motor 64. The driving disc 61 is arranged inside the sowing cavity. The second rotating shaft 62 is arranged vertically and is rotationally connected with the base 1. The driving disc 61 is coaxially welded with the second rotating shaft 62. The driving disc 61 is close to the base 1 without abutting against the base 1, so that the driving disc 61 can rotate freely. The driving blades 63 are arranged in plurality and are located on the side of the driving disc 61 close to the layer plate 31. One end of the driving blade 63 is welded with the second rotating shaft 62. In this embodiment, the driving blades 63 are arranged in eight. The plurality of driving blades 63 are arranged at equal intervals on the circumferential side of the second rotating shaft 62. The driving motor 64 is a servo motor. The driving motor 64 is arranged inside the base 1 and is used to drive the second rotating shaft 62 to rotate. As an alternative embodiment, the driving motor 64 can be replaced by a manual rocker. By extending the manual rocker out of the base 1, the worker can realize the rotation of the second rotating shaft 62 by rotating the manual rocker.

[0044] When the sowing driving assembly 6 pushes the sowing cavity, the driving motor 64 is started to drive the second rotating shaft 62 to rotate. The driving disc 61 and the driving blades 63 rotate with the second rotating shaft 62. The seeds in the seed storage box 2 are separated from the seed storage box 2 through the discharge opening by gravity and fall onto the driving disc 61 and are located between adjacent driving blades 63. When the seeds on the driving disc 61 are pushed to the sowing opening by the rotation of the driving blades 63, the seeds are thrown out of the sowing cavity from the sowing opening under the action of centrifugal force and inertia, realizing directional sowing.

[0045] In order to improve the space utilization efficiency and reduce the size of the sowing device, the fixed plate 32 is arranged as an arc plate with the same diameter as the driving disc 61. In this embodiment, the fixed plate 32 is a standard semicircular arc plate, as shown in Figure 4As shown, the driving disc 61 is coaxially arranged with the fixed plate 32, the driving blade 63 is tangent to the side surface of the driving disc 61 away from the second rotating shaft 62, the bottom surface of the driving blade 63 is welded and fixed with the driving disc 61, and the top surface of the driving blade 63 is close to the bottom surface of the layer plate 31, so that the seeds falling into the driving disc 61 are all located in the pushing range of the driving blade 63, the possibility of the seeds failing to be pushed out of the seeding cavity is reduced, and thus the seeds in the seed storage box 2 can be effectively sown.

[0046] Please refer to Figure 5 The driving motor 64 is arranged in the base 1, space can be effectively saved, and the occupied area of the seeding device is reduced. In addition, the hollow base 1 can also reduce the weight of the seeding device.

[0047] The first bevel gear 65 and the second bevel gear 66 are arranged to be engaged with each other between the driving motor 64 and the second rotating shaft 62, the axes of the first bevel gear 65 and the second bevel gear 66 are arranged to be perpendicular to each other, the first bevel gear 65 is coaxially fixedly connected with the second rotating shaft 62 through a pin key connection mode, and the second bevel gear 66 is coaxially fixedly connected with the output shaft of the driving motor 64 through a pin key connection mode. The first bevel gear 65 and the second bevel gear 66 can make the output shaft of the driving motor 64 perpendicular to the second rotating shaft 62. Since the length of the driving motor 64 is usually greater than the diameter of the driving motor 64, the transversely arranged driving motor 64 can reduce the thickness of the base 1. In addition, by changing the transmission ratio of the first bevel gear 65 and the second bevel gear 66, the second rotating shaft 62 can be accelerated or decelerated. In the embodiment, the first bevel gear 65 and the second bevel gear 66 are consistent in size.

[0048] In order to further improve the convenience of the seeding device, the driving button 8 is arranged at the top of the handle 5, and the driving button 8 is electrically connected with the driving motor 64. When the staff holds the handle 5, the thumb can press or release the driving button 8 at any time, so that the seeding driving assembly 6 can be stopped or started, and the seeding can be stopped or started at any time.

[0049] In order to facilitate power supply for the driving motor 64, the battery box 7 is further arranged between the layer plate 31 and the bottom plate. The battery box 7 is a round rectangular box body, and the battery is located away from the movable plate 33 on one side of the fixed plate 32. The battery box 7 is internally provided with a storage battery. As an alternative embodiment, the storage battery can also be a nickel-hydrogen battery or a nickel-cadmium battery, etc. The storage battery is electrically connected with the driving motor 64 to provide power for the driving motor 64.

[0050] One side of the battery box 7 is provided with a charging port 71, the storage battery can be charged at any time through the charging port 71, so that the storage battery can maintain functionality. Compared with replacing the battery, the use cost and convenience can be effectively reduced.

[0051] Please refer toFigure 2 In order to improve the structural stability of the seeding device, the top and bottom of the battery box 7 are fixedly connected with the layer plate 31 and the bottom plate respectively through bolts; the bottom of the side of the seed storage box 2 away from the seeding opening is chamfered, and a vertical column 23 is arranged between the inclined edge of the chamfer and the layer plate 31, the top and bottom of the vertical column 23 are welded and fixed with the seed storage box 2 and the layer plate 31 respectively, a connecting rod is welded and fixed on one side of the top of the handle 5 in the vertical direction, and one end of the connecting rod away from the handle 5 is welded and fixed with the vertical column 23. By arranging the vertical column 23 and the battery box 7, the seed storage box 2 and the base 1 are connected as a whole, so as to improve the structural stability of the seeding device.
