[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0032] Those skilled in the art can understand that although some of the embodiments herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of the present utility model and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0033] The following refers to the attached Figure 1 to the attached Figure 13 to describe a seeding device of the present utility model.

[0034] A robot includes a moving component 1 for the movement of the robot. A support component 3 is provided on the moving component 1, and the support component 3 can rotate relative to the moving component 1. A first sliding component 7 is provided on the support component 3, and the first sliding component 7 can slide relative to the support component 3. A second sliding component 6 is provided on the first sliding component 7, and the second sliding component 6 can slide relative to the first sliding component 7. The sliding direction of the second sliding component 6 is perpendicular to the sliding direction of the first sliding component 7. A seeding device 8 is connected to the second sliding component 6.

[0035] By providing the moving component 1, the robot can move straight and turn; by providing the support component 3, the first sliding component 7, the second sliding component 6, and the seeding device 8 of the robot can rotate relative to the moving component 1 to change the orientation of the seeding device 8 of the robot; by providing the first sliding component 7, the second sliding component 6 and the seeding device 8 of the robot can slide relative to the support component 3 to change the height of the seeding device 8 of the robot; by providing the second sliding component 6, the seeding device 8 of the robot can slide horizontally relative to the first sliding component 7 to change the extending length of the seeding device 8 of the robot.

[0036] A supporting component 2 is provided on the moving component, and the supporting component 2 can be used to place various frames.

[0037] The moving component 1 includes a first moving base 11 and a second moving base 12. The first moving base 11 and the second moving base are hinged by a connecting shaft. The first moving base 11 is provided with a first moving wheel 13 and a second moving wheel 14, and the second moving base 12 is provided with a third moving wheel 15. In this embodiment, by providing the first moving base 11 and the second moving base 12 and hinging the first moving base 11 and the second moving base 12, it is possible to adapt to road surfaces with different slopes and achieve the smooth movement of the moving component 1.

[0038] The bracket component 3 includes a support rod 31 and a turntable 32. The support rod 31 and the turntable 32 are fixedly connected. The turntable 32 is rotatably connected to the moving component 1. A third motor 33 is fixedly connected to the support rod 31. The output end of the third motor 33 is fixedly connected with a first gear 34. The turntable 32 is fixedly connected with a second gear 35 through a gear shaft. The first gear 34 meshes with the second gear 35. A toothed ring 36 is provided inside the turntable 32. The toothed ring 36 meshes with the second gear 35. The third motor 33 drives the bracket to rotate relative to the moving component 1 through the first gear 34, the second gear 35 and the toothed ring 36.

[0039] When the third motor 33 is started, the first gear 34 thereon rotates. Since the first gear 34 meshes with the second bevel gear and the toothed ring 36 meshes with the second gear 35, the toothed ring 36 drives the turntable 32 to rotate, so that the bracket component 3 can rotate relative to the moving component 1, and the rotation direction of the bracket component 3 is controlled by the rotation direction of the third motor 33.

[0040] The first sliding component 7 includes a first sliding member 4 and a second sliding member 5. The first sliding member 4 is connected to the bracket component 3, and the second sliding member 5 is connected to the second sliding component 6. The sliding directions of the first sliding member 4 and the second sliding member 5 are the same. When the first sliding member 4 slides relative to the bracket component 3, the second sliding member 5 slides relative to the first sliding member 4, so as to increase the sliding speed of the seeding device 8. The distance that the second sliding member 5 slides is twice the distance that the first sliding member 4 slides.

[0041] The first sliding member 4 includes a first sliding frame 41 and a first rack 46. The first sliding frame 41 is slidably connected to the support rod 31. A first motor 42 is fixedly connected to the first sliding frame 41. The output end of the first motor 42 is fixedly connected with a third gear 43. A first rotating rod is rotatably connected to the first sliding frame 41. A fourth gear 44 and a fifth gear 45 are fixedly connected to the first rotating rod. The third gear 43 meshes with the fourth gear 44. The fifth gear 45 meshes with the first rack 46. The first rack 46 is fixedly connected to the support rod 31. The first motor 42 can drive the first sliding frame 41 to slide vertically relative to the bracket component 3 through the third gear 43, the fourth gear 44, the fifth gear 45 and the first rack 46. The first sliding frame 41 is connected to the second sliding member 5.

[0042] By starting the first motor 42, the third gear 43 thereon rotates. Since the third gear 43 meshes with the fourth gear 44, the fifth gear 45 meshes with the first rack 46, and the first rack 46 is fixedly connected to the support rod 31, when the third gear 43 rotates, it slides relative to the first rack 46, enabling the first sliding frame 41 to slide up and down relative to the support rod 31, and the sliding direction of the first sliding frame 41 is controlled by the rotation direction of the first motor 42.

[0043] The second sliding member 5 includes a first sprocket 51, a second sprocket 52 and a second sliding frame 55. The first sprocket 51 is fixedly connected to the output end of the first motor 42. A second rotating rod is rotatably connected to the first sliding frame 41, and the second rotating rod is fixedly connected to the second sprocket 52. The first sprocket 51 and the second sprocket 52 are connected by a chain. A first synchronous pulley 53 is fixedly connected to the second rotating rod. A third rotating rod is rotatably connected to the first sliding frame 41, and a second synchronous pulley 54 is fixedly connected to the third rotating rod. The first synchronous pulley 53 and the second synchronous pulley 54 are connected by a timing belt. The second sliding frame 55 is slidably connected to the first sliding frame 41, and a timing belt clip 56 is fixedly connected to the second sliding frame 55. The timing belt clip 56 is fixedly connected to the timing belt, so as to drive the second sliding frame 55 to slide vertically relative to the first sliding frame 41 through the timing belt. The second sliding frame 55 is connected to the second sliding assembly 6.

[0044] When the third gear 43 rotates, at the same time, the first sprocket 51 rotates synchronously. Since the first sprocket 51 and the second sprocket 52 are connected by a chain, the second sprocket 52 rotates, thereby the first synchronous pulley 53 rotates. Since the first synchronous pulley 53 and the second synchronous pulley 54 are connected by a timing belt, the second synchronous pulley 54 rotates, and the timing belt moves. Since the timing belt clip 56 is fixedly connected to the timing belt, the second sliding frame 55 slides synchronously, and the sliding direction is the same as that of the first sliding frame 41. Thus, the sliding distance of the second sliding frame 55 is twice the sliding distance of the first sliding frame 41, thereby improving the sliding efficiency of the first sliding assembly 7.

[0045] The second sliding assembly 6 includes a slide rail 61. The slide rail 61 is fixedly connected to the second sliding frame 55. A third sliding frame 62 is slidably connected to the slide rail 61. The third sliding frame 62 is connected to the seeding device 8. A second rack 63 is fixedly connected to the third sliding frame 62. A second motor 64 is fixedly connected to the slide rail 61. The output end of the second motor 64 is fixedly connected to a sixth gear 65. The sixth gear 65 meshes with the second rack 63.

[0046] By starting the second motor 64, the sixth gear 65 thereon rotates. Since the sixth gear 65 meshes with the second rack 63, and the second rack 63 is fixedly connected to the third sliding frame 62, the third sliding frame 62 can slide laterally relative to the sixth gear 65, and the sliding direction of the third sliding frame 62 is controlled by the rotation direction of the third motor 33.

[0047] A material taking component 9 is provided on the second sliding component 6. The material taking component 9 is located above the sowing device 8. The material taking component 9 puts the seeds in the seed box into the sowing device 8, and the material taking component 9 dredges the outlet of the seed box.

[0048] The material taking component 9 includes a support 91. A seventh gear 92 is fixedly connected to the support 91. A material taking block 93 is fixedly connected to the seventh gear 92. A clamping cavity 94 is provided between the material taking blocks 93. The switch on the seed box is clamped through the clamping cavity 94, and then the switch on the seed box is rotated while being clamped, so as to put the seeds in the seed box into the sowing device 8. A third rack 95 is slidably connected to the support 91. The third rack 95 meshes with the seventh gear 92. One end of the third rack 95 dredges the outlet of the seed box, avoiding the outlet of the seed box being blocked by seeds.

[0049] The seed box is placed at a fixed position. When material taking is required, the sowing device 8 is moved to the position of the seed box through the moving component 1. Through the first sliding component 7, the height of the sowing device 8 is adjusted, so that the sowing device 8 is placed below the seed box. Through the second sliding component 6, the lateral direction of the sowing device 8 is adjusted, so that the sowing device 8 is moved to the same arc as the seed box. Through the support component 3, the angle of the sowing device 8 in the horizontal plane is adjusted, so that the sowing device 8 is placed directly below the seed box. After the position of the sowing device 8 is adjusted, at this time, the clamping cavity 94 clamps the switch on the seed box, and then the seventh gear 92 rotates relative to the support 91, and further the material taking block 93 rotates, rotating the switch on the seed box, opening the outlet of the seed box, and the seeds fall from the seed box into the sowing device 8. The third rack 95 dredges the outlet of the seed box, completing the automatic material taking of the seeds.

[0050] The seeding device 8 includes a housing 81. A plurality of spiral channels are provided inside the housing 81. One type of seed is placed in each spiral channel. The outlets of the plurality of spiral channels are all connected to a switching member 82. One end of the switching member 82 away from the spiral channels is connected to a discharge tube 83. The discharge tube 83 is provided with a plurality of discharge ports 831. When the switching member 82 rotates, one of the plurality of spiral channels is opened, so that one type of seed slides through the switching member 82 to the corresponding discharge port 831. A control assembly is provided at the discharge port 831. The control assembly rotates to open the plurality of discharge ports 831 together, so that the seeds in the plurality of discharge ports 831 are sown to the position to be sown simultaneously through the control assembly. It can automatically realize the simultaneous switching of sowing different seeds, without the need for manual shutdown to replace the seeds and then sow. Moreover, during the sowing process, multiple types of seeds can be sown simultaneously, reducing the labor intensity of workers, having a high degree of automation, and multiple types of seeds landing simultaneously, greatly improving the sowing efficiency.

[0051] The spiral channels include a first spiral channel 811 and a second spiral channel 812. The first spiral channel 811 and the second spiral channel 812 are arranged in an intersecting manner. The axis of the first spiral channel 811 is coaxial with the axis of the second spiral channel 812. In other embodiments, the number of spiral channels can also be three, four or other numbers. According to the number of types of seeds to be sown, the number of spiral channels is set accordingly. In this embodiment, two spiral channels are provided, namely the first spiral channel 811 and the second spiral channel 812, and they are set as spiral-shaped channels. On the one hand, it is convenient to store a relatively large number of seeds in the spiral channels. On the other hand, it is convenient for the seeds to move in the spiral channels and be sown to the position to be sown.

[0052] Furthermore, a feed tube 85 is provided on the housing 81. A first through hole 851 is opened on the feed tube 85. The feed tube 85 can rotate relative to the bracket so that the first through hole 851 communicates with the inlet of the first spiral channel 811 or the inlet of the second spiral channel 812, so as to place one type of seed in the first spiral channel 811 or the second spiral channel 812.

[0053] Specifically, a conical inlet structure is provided inside the feeding cylinder 85, and the first through hole 851 is provided on the conical structure, facilitating the seeds to enter the first spiral channel 811 or the second spiral channel 812 through the first through hole 851 of the conical structure. The feeding cylinder 85 rotates relative to the bracket, enabling the first through hole 851 to communicate with the first spiral channel 811, and transporting one type of seeds into the first spiral channel 811. The feeding cylinder 85 rotates relative to the bracket, enabling the first through hole 851 to communicate with the second spiral channel 812, and transporting another type of seeds into the second spiral channel 812. By the rotation of the feeding cylinder 85 relative to the bracket, different types of seeds are placed into different spiral channels, allowing different types of seeds to be loaded at one time, realizing the sowing of different seeds, reducing the labor intensity of workers for replacing seeds, and improving the sowing efficiency.

[0054] Furthermore, a linear channel 821 is formed on the switching member 82. The switching member 82 can rotate relative to the housing 81 to enable the linear channel 821 to communicate with the outlet of the first spiral channel 811 and / or the outlet of the second spiral channel 812, so as to move the seeds in the first spiral channel 811 and / or the second spiral channel 812 to the corresponding discharge ports 831 through the linear channel 821. By providing the linear channel 821, it is convenient to pre-store the seeds from the first spiral channel 811 or the second spiral channel 812 in the linear channel 821, and when seeds need to be sown to the position to be sown, the seeds in the linear channel 821 are then sown into the discharge ports 831.

[0055] Preferably, the specific number of the linear channels 821 is two. In other embodiments of the present invention, one of the linear channels 821 can also be blocked by a baffle 822, so that the linear channel 821 is equivalent to one.

[0056] Furthermore, two discharge ports 831 are symmetrically provided on the discharge cylinder 83. When one of the linear channels 821 is blocked by the baffle 822, the switching member 82 rotates relative to the housing 81 and communicates with any one of the two discharge ports 831 to sow the seeds on different linear trajectories. Among them, when the first spiral channel 811 or the second spiral channel 812 is in communication with the linear channel 821, the linear channel 821 is not in communication with the second through hole 84. When the linear channel 821 is in communication with the second through hole 84, the first spiral channel 811 or the second spiral channel 812 is not in communication with the linear channel 821.

[0057] During the actual sowing process, to improve the sowing efficiency, the sowing of two rows of seeds can be carried out simultaneously. When there are two linear channels 821, the two seeds are simultaneously transferred to the discharge ports 831 through the two linear channels 821. When there is one linear channel 821, that is, the seeds are first sown into one discharge port 831, and then the seeds are sown into the other discharge port 831.

[0058] Furthermore, the control assembly includes two control cylinders 84. Each discharge port 831 is controlled by a corresponding control cylinder 84, and the two control cylinders 84 rotate simultaneously, so that the seeds at the two discharge ports 831 are simultaneously sown from the discharge ports 831 to the positions to be sown. A second through hole 84 is provided in the control cylinder 84. The control cylinder 84 rotates relative to the discharge port 831 to connect the discharge port 831 with the second through hole 84. The seeds are sown to the positions to be sown through the discharge port 831 and the second through hole 84 simultaneously. After seeds are contained in both discharge ports 831, the control cylinder 84 is started, so that the second through hole 84 of the control cylinder 84 is connected with the discharge port 831, and thus the seeds at the two discharge ports 831 are simultaneously sown from the discharge ports 831 to the positions to be sown. When there are no seeds at the two discharge ports 831, the control cylinder 84 is closed, so that the control cylinder 84 blocks the discharge port 831 and the discharge port 831 is not connected to the outside.

[0059] Preferably, the control cylinder 84 is circular, so that when the control cylinder 84 is switched from the closed state to the open state, the seeds will not interfere with the control cylinder 84.

[0060] The sowing device 8 further includes a first driving assembly. The first driving assembly is arranged on the discharge cylinder 83. The first driving assembly is respectively connected to the feeding cylinder 85 and the switching member 82 to drive the feeding cylinder 85 and the switching member 82 to rotate relative to the housing 81. Specifically, the first driving assembly includes a first driving motor, a first driving shaft 823, a first connecting member 824 and a second connecting member 825. The first driving motor is arranged on the discharge cylinder 83. The driving end of the first driving motor is connected to the first driving shaft 823. The first connecting member 824 and the second connecting member 825 are sleeved on the first driving shaft 823 at intervals. The first connecting member 824 is fixedly connected to the feeding cylinder 85, and the second connecting member 825 is fixedly connected to the switching member 82. The first driving motor rotates, and then drives the first driving shaft 823 to rotate. Then, the rotation of the feeding cylinder 85 relative to the bracket is realized through the first connecting member 824, and the rotation of the switching member 82 relative to the bracket is realized through the second connecting member 825. In this embodiment, the rotation of the feeding cylinder 85 and the switching member 82 relative to the bracket is realized by one driving motor. In other embodiments, the feeding cylinder 85 and the switching member 82 can be respectively connected to a driving motor to respectively control the rotation of the feeding cylinder 85 and the switching member 82 relative to the bracket.

[0061] The seeding device 8 further includes a second driving assembly. The second driving assembly is disposed on the discharge cylinder 83 and is connected to the control cylinder 84 to drive the control cylinder 84 to rotate relative to the discharge cylinder. Specifically, the second driving assembly includes a second driving motor. The second driving motor is disposed on the discharge cylinder 83. The driving end of the second driving motor is connected to a second driving shaft, and the second driving shaft is fixedly connected to the control cylinder 84. When the second driving motor rotates, it drives the second driving shaft to rotate, thereby realizing the rotation of the control cylinder 84 relative to the discharge port 831.

[0062] Furthermore, the seeding robot further includes a detection assembly. The detection assembly is disposed on one side of the discharge cylinder 83 close to the seeding position to detect the seeding position. Before seeding, during the movement of the moving assembly 1, the detection assembly detects the situation of the seeding position in real time. When the seeding position is detected, the moving assembly 1 stops moving and seeds the seeds to the seeding position. Specifically, the detection assembly includes a limit switch and a sensing member. Since the seeding position is lower than the normal ground, when the sensing member is not at the seeding position, the limit switch is in one signal state, and when the sensing member is placed at the seeding position, the limit switch is in another signal state, realizing the detection of the seeding position, which is convenient for subsequent seeding of the seeds to the seeding position.

[0063] Furthermore, the seeding device 8 further includes a limiting member. The limiting member is disposed on the discharge cylinder 83. There are two limiting members, and the two limiting members are respectively disposed on both sides of the discharge cylinder 83. The two limiting members are used to limit the left-right direction of the first spiral channel 811 and the second spiral channel 812.

[0064] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
