[0054] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0055] like Figures 1 to 9 As shown, an embodiment of the utility model provides an automatic sowing and feeding device, comprising: a mobile base 1; a third U-shaped support plate 4, both ends of which are fixedly connected to the mobile base 1; a feeding assembly, arranged on the top of the third U-shaped support plate 4; a first U-shaped support plate 2, both ends of which are fixedly connected to the mobile base 1; a feeding assembly, arranged on the top of the first U-shaped support plate 2; and an intermittent transmission assembly connected to the feeding assembly.

[0056] In the embodiment of the utility model, the seeds can be evenly delivered to the dropping assembly through the feeding assembly, and then precise intermittent dropping can be achieved through the intermittent transmission assembly, thereby achieving uniform sowing of the seeds.

[0057] like Figure 3 As shown, the feeding assembly includes: a support seat 9, connected to the top of the third U-shaped support plate 4; a first motor 8, fixedly connected to the support seat 9; a support shaft 24, one end of which is fixedly connected to the top of the third U-shaped support plate 4; a transport tube 7, fixedly connected to the other end of the support shaft 24, and a blanking port is provided at the top of the transport tube 7; a spiral rod 15, one end of which is fixedly connected to the output end of the first motor 8, and the other end is sleeved on the transport tube 7; a connecting ring 25, one end of which is fixedly connected to the blanking port on the transport tube 7; and a speed regulating assembly is arranged on the connecting ring 25.

[0058] In the embodiment of the utility model, the seeds enter the transport tube 7 through the drop port at the top of the transport tube 7, and then the first motor 8 is turned on to drive the screw rod 15 to rotate, so that the seeds move to the other end of the transport tube 7 as the screw rod 15 rotates. After reaching the other end, the seeds will break away from the transport tube 7 and fall onto the drop assembly due to the action of gravity. Among them, the setting of the screw rod 15 allows the seeds to fall evenly onto the drop assembly to avoid blockage.

[0059] like Figure 5 As shown, the speed regulating assembly includes: an aperture 6, which is clamped on the inner wall of the connecting ring 25; a sliding groove, which is arranged on the connecting ring 25; and a paddle 14, which is slidably connected to the sliding groove.

[0060] In the embodiment of the utility model, the size of the aperture 6 can be adjusted by manually turning the paddle 14, and the appropriate aperture 6 can be selected by sowing seeds of different sizes, thereby avoiding the aperture 6 opening being too large, causing a large number of seeds to be blocked at the drop port of the transport tube 7, and coordinating with the rotation speed of the screw rod 15 to achieve uniform and unobstructed seed transportation.

[0061] like Figure 7 As shown, the blanking assembly includes: a mounting block 13, which is bolted to the first U-shaped support plate 2; a blanking tube 16, which is fixedly connected to the mounting block 13 and one end of which is passed through the movable base 1; a placing disc 10, which is fixedly connected to the other end of the blanking tube 16; and an anti-blocking assembly, which is arranged on the placing disc 10.

[0062] In the embodiment of the utility model, seeds can enter the drop tube 16 and then flow along the drop tube 16 to the lower end, pass through the mobile base 1, and fall on the designated land; wherein, at the connection between the drop tube 16 and the mobile base 1, a slide groove is provided on the mobile base 1, which allows the drop tube 16 to slide left and right, so as to facilitate the adjustment of the position of the drop tube 16.

[0063] like Figure 3 As shown, the anti-blocking component includes: a first rotating rod 17, one end of which is passed through the bottom end of the placing disc 10, and the other end is connected to the intermittent transmission component and is rotatably connected to the placing disc 10; a sieve plate 12 is fixedly connected to one end of the first rotating rod 17; a brush 11, one end of which is fixedly connected to the inner wall of the placing disc 10, and the other end is slidably connected to the sieve plate 12.

[0064] In the embodiment of the utility model, the drop port of the transport tube 7 is arranged at the upper end of the placement disc 10. After the seeds fall, they will fall on the sieve plate 12 and rotate with the sieve plate 12. Since the lower end of the sieve plate 12 is in contact with the placement disc 10, when it rotates to the brush 11, the brush 11 will sweep the seeds evenly, so that the seeds all fall into the through holes on the sieve plate 12, and the lower end is in contact with the placement disc 10; since the placement disc 10 is connected to the drop pipe 16, when the seeds rotate to the top of the drop pipe 16 as the sieve plate 12 rotates, they will fall down under the action of gravity, thereby completing the drop of the seeds; wherein, the sieve plates 12 with through holes of different sizes can be replaced according to the sizes of different seeds, and at the same time, the sieve plates 12 with through holes of different densities can be replaced according to the number of seeds to be dropped at one place.

[0065] like Figure 8 As shown, the intermittent transmission assembly includes: an intermittent wheel 18, fixedly connected to the other end of the first rotating rod 17; a second motor 20, fixedly connected to the movable base 1; a rotating disc 19, fixedly connected to the output end of the second motor 20; a first limiting rod 22, one end of which is fixedly connected to the rotating disc 19 and the other end is slidably connected to the intermittent wheel 18; an arc-shaped turntable 21, fixedly connected to the rotating disc 19 and meshingly connected to the intermittent wheel 18.

[0066] In the embodiment of the utility model, the intermittent wheel 18 is provided with a plurality of sliding grooves distributed in a circumference; the second motor 20 is turned on to drive the rotating disc 19 to rotate, and the rotating disc 19 drives the first limiting rod 22 to rotate. When the first limiting rod 22 rotates with the rotating disc 19, it will enter the sliding groove on the intermittent wheel 18, thereby driving the intermittent wheel 18 to rotate at a certain angle. After the intermittent wheel 18 rotates at a certain angle, the first limiting rod 22 will be separated from the sliding groove on the intermittent wheel 18, so that the intermittent wheel 18 stops rotating. When the first limiting rod 22 rotates one circle and turns to the sliding groove on the intermittent wheel 18 again, it can drive the intermittent wheel 18 to rotate at a certain angle again, so that the intermittent wheel 18 rotates intermittently; and the rotation of the intermittent wheel 18 will drive the sieve plate 12 to rotate intermittently, so that the time for the seeds to fall into the drop tube 16 has a certain interval, and then with the uniform movement of the mobile base 1, the drop sowing at the same distance can be realized; wherein the interval drop can be adjusted by adjusting the speed of the second motor 20.

[0067] like Figure 2 As shown, a second U-shaped support plate 3 is fixedly connected to the top of the mobile base 1, the second U-shaped support plate 3 is located between the first U-shaped support plate 2 and the third U-shaped support plate 4, and the second U-shaped support plate 3 is in contact with the bottom end of the placement disc 10; a plurality of mounting holes 23 are opened on the top of the first U-shaped support plate 2.

[0068] In the embodiment of the utility model, since a plurality of mounting holes 23 are provided at the top of the first U-shaped support plate 2, the mounting block 13 can be installed at different positions on the first U-shaped support plate 2 by installing and disassembling bolts, and the distance between the two drop tubes 16 can be adjusted by cooperating with the two sets of drop assembly and feeding assembly provided on the mobile base 1, so as to better adapt to different sowing environments.

[0069] Working principle: first, turn the paddle 14 to adjust the size of the aperture 6, then turn on the first motor 8 to drive the screw rod 15 to rotate, then put the seeds in the funnel 5, the seeds rotate with the screw rod 15, and then fall onto the sieve plate 12, turn on the second motor 20, drive the rotating disc 19 to rotate, the rotating disc 19 drives the first limit rod 22 to rotate, the first limit rod 22 drives the intermittent wheel 18 to rotate intermittently, thereby driving the sieve plate 12 to rotate intermittently, so that the seeds on the sieve plate 12 intermittently fall into the drop pipe 16, and then fall on the designated land to complete the drop.

[0070] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
