[0039] Reference Figures 1-13 A sowing device for agricultural planting includes a vehicle body 1. Two groups of support seats 2 that cooperate with each other in front and back are fixedly installed on the bottom of the vehicle body 1, and rotating shafts 3 are rotatably installed on the two groups of support seats 2. Anti-skid wheels 4 are fixedly installed on the front and rear ends of the two rotating shafts 3. The design of multiple anti-skid wheels 4 allows the vehicle body 1 to move smoothly in the farmland.

[0040] The machine also includes a coating part, which is used to coat the crop seeds. The coating part includes a mixing drum 8 fixedly mounted on the vehicle body 1 through two vertical plates 7. A rotating rod 10 is rotatably mounted in the mixing drum 8, and a plurality of mixing rods 11 are fixedly mounted on the rotating rod 10. A feeding hopper 9 is fixedly mounted on the top of the mixing drum 8. In some areas with poor soil or serious pests and diseases, in order to improve the survival rate of crop seeds, they are usually coated before sowing, that is, corresponding fertilizers and pesticides are mixed on the surface of the crop seeds. Generally, the coating treatment is completed in advance using a coating machine and cannot be performed during the sowing process. By cooperating with the mixing drum 8 and the feeding hopper 9, before sowing the crop seeds, an appropriate amount of crop seeds, fertilizers, pesticides, etc. can be put into the mixing drum 8 together for mixing to complete the coating. Therefore, there is no need for advance treatment, which can greatly improve the sowing efficiency.

[0041] When using the device specifically, the coating materials are put into the mixing drum 8 according to the selection of different coating materials and their ratios, and according to the setting of the gears on the existing agricultural machinery traveling in the farmland, an idle gear is also set on the driving shaft of the anti-skid wheel 4, so that the dual-axis motor 15 does not drive the anti-skid wheel 4 to rotate when working in the idle gear. At this time, the dual-axis motor 15 only drives the mixing rod 11 to rotate when working, so that the crop seeds have sufficient coating treatment time, and thus it can be ensured that the fallen crop seeds are all coated seeds.

[0042] The separation and sowing part is used to separate and sow crop seeds. The separation and sowing part includes a collecting box 12 fixedly connected to the bottom of the mixing barrel 8. A drop-out port is provided at the bottom of the mixing barrel 8. The drop-out port is not shown in the figure. The purpose of its design is to allow the crop seeds to fall smoothly into the collecting box 12, so as to facilitate the subsequent direct sowing process.

[0043] A shielding assembly that cooperates with the rotating rod 10 is installed in the mixing drum 8. The shielding assembly is used to prolong the residence time of the crop seeds in the mixing drum 8. The shielding assembly consists of a baffle 42, two mounting rings 40, two connecting rods 41 and two rotating mechanisms. The two mounting rings 40 are rotatably installed in the mixing drum 8. The baffle 42 is fixedly connected to the corresponding mounting ring 40 through the two connecting rods 41. The initial position of the baffle 42 is above the drop port. The existence of the baffle 42 can block the drop port to prevent the crop seeds from falling directly into the collection box 12 for sowing before being coated.

[0044] The rotating mechanism is composed of an incomplete gear ring 43, a connecting gear 44 and an incomplete gear ring 45. The incomplete gear ring 43 is fixedly mounted on the rotating rod 10. A circular shaft is rotatably mounted in the mixing drum 8. The connecting gear 44 is fixedly mounted on the circular shaft, and the connecting gear 44 cooperates with the incomplete gear ring 43. The incomplete gear ring 45 is fixedly mounted on the inner wall of the mounting ring 40, and the incomplete gear ring 45 is meshed with the connecting gear 44. Through the cooperation of the incomplete gear ring 43, the connecting gear 44 and the incomplete gear ring 45, the incomplete gear ring 43 can be meshed with the connecting gear 44 after the rotating rod 10 rotates a certain angle, and then the rotation of the connecting gear 44 can drive the incomplete gear ring 45 to rotate, so that the mounting ring 40 rotates in the mixing drum 8 to move the baffle 42 away from the upper end of the blanking port. At this time, part of it has been coated. The crop seeds fall into the collecting box 12 and participate in the subsequent sowing process, which ensures the coating treatment effect of the crop seeds. By designing the respective sizes of the incomplete gear ring 43, the connecting gear 44 and the incomplete gear ring 45, the time for the baffle 42 to move away from the upper end of the drop port can be controlled each time, so that it is moved when the incomplete gear 25 is about to separate from the fixed gear 27, so that a certain amount of crop seeds can be automatically sent into the collecting box 12 before sowing. In addition, a coaxial torsion spring is installed between the connecting gear 44 and the mixing drum 8. By utilizing the effect of the torsion spring, when the incomplete gear ring 43 is separated from the connecting gear 44, the torsion spring can allow the baffle 42 to block the drop port, so that the crop seeds in the mixing drum 8 can continue to be more fully mixed with the coating material.

[0045] The bottom of the collection box 12 is fixedly connected to a separation bucket 13, and the bottom of the separation bucket 13 is fixedly connected to multiple conveying pipes 14. A blanking assembly is installed on the separation bucket 13, and the blanking assembly cooperates with the rotating rod 10 and multiple conveying pipes 14. The blanking assembly consists of a rotating shaft 30, a blanking plate 31, a blanking rod 32 and multiple blanking holes 33. The rotating shaft 30 is rotatably connected to the separation bucket 13, and the blanking plate 31 is fixedly installed in the separation bucket 13. A plurality of circular holes are evenly arranged on the blanking plate 31, and each circular hole is fixedly installed in the separation bucket 13. The holes correspond to the positions of the corresponding drop holes 33 respectively. The drop rod 32 is fixedly mounted on one end of the rotating shaft 30 located in the separation bucket 13, and the drop rod 32 is located between the drop plate 31 and multiple conveying pipes 14. Multiple drop holes 33 are all opened on the drop rod 32, and each drop hole 33 is located above the corresponding conveying pipe 14. The crop seeds that fall into the collecting box 12 will pass through the circular holes and the drop holes 33 into the conveying pipe 14, and fall from the conveying pipe 14 to realize sowing processing.

[0046] Since the drop rod 32 rotates in the separation bucket 13, and the space at the bottom of the drop plate 31 in the separation bucket 13 is sealed and rotated with the drop rod 32, the crop seeds located above the drop plate 31 will fall down to complete the sowing when the drop hole 33 is rotated to align with the circular hole and the conveying pipe 14. When the drop hole 33 on the drop rod 32 is intertwined with the circular hole, the crop seeds will not fall down for sowing. A belt drive structure 39 is installed between the end of the rotating rod 10 away from the belt drive structure 16 and the rotating shaft 30. Under the design of the belt drive structure 39, when the rotating rod 10 rotates, it can simultaneously drive the rotating shaft 30 to rotate, so that the drop rod 32 rotates in the separation bucket 13, realizing intermittent crop seed sowing processing without the need for an additional power device.

[0047] The power unit is used to drive the operation of the vehicle body 1 and the rotating rod 10. The power unit includes a dual-axis motor 15 fixedly mounted on the vehicle body 1, a power box 5 that matches the dual-axis motor 15 is fixedly mounted on the vehicle body 1, and an armrest 6 is fixedly mounted on the side wall of the power box 5 away from the mixing barrel 8. The function of the armrest 6 is to facilitate the user to control the planting equipment. An incomplete gear 25 is fixedly mounted on the output end of the dual-axis motor 15, a transmission rod 26 is rotatably mounted in the power box 5, and a fixed gear 27 that matches the incomplete gear 25 is fixedly mounted on the transmission rod 26. A belt transmission structure 28 is installed between the transmission rod 26 and one of the rotating shafts 3, and the incomplete gear The wheel 25 cooperates with the fixed gear 27, and when the dual-axis motor 15 is working, it can drive the transmission rod 26 to rotate at the same time, and the rotation mode of the transmission rod 26 is to stop after rotating a certain angle, and then continue to rotate for a certain angle and then stop. When the transmission rod 26 rotates, due to the design of the belt transmission structure 28, it will drive the rotating shaft 3 to rotate, and at this time it can provide drive for the operation of the anti-skid wheel 4, so that the planting equipment stops for a period of time after traveling a certain distance in the farmland, and then travels again, that is, the driving mode of the planting equipment is to stop after traveling a certain distance each time, so sowing during the stopping time can ensure that the sowing position and depth are not affected by the operation of the equipment, and the sowing effect can be ensured.

[0048] A belt transmission structure 16 is installed between the output end of the other end of the dual-axis motor 15 and the rotating rod 10. Under the action of the belt transmission structure 16, the dual-axis motor 15 can simultaneously provide drive for the rotation of the rotating rod 10 when working. Therefore, the equipment can continuously coat the crop seeds while driving. At the same time, since a belt transmission structure 39 is installed between the other end of the rotating rod 10 and the rotating shaft 30, the sowing process will also be carried out at the same time. By designing the initial angle of the rotating shaft 30, when the incomplete gear 25 is separated from the fixed gear 27 and has not yet engaged for the second time, the blanking hole 33 on the blanking rod 32 is just aligned with the conveying pipe 14, so that the sowing process can be completed when the driving stops.

[0049] The depth adjustment part is used to adjust the sowing depth. The depth adjustment part includes a movable plate 18 that is slidably arranged on the vehicle body 1, and a connecting plate 29 is slidably arranged at the bottom of the movable plate 18. A plurality of sowing tubes 24 that are sealed and slidably matched with the corresponding conveying pipes 14 are fixedly installed on the side wall of the connecting plate 29 through a plurality of support rods 23. The sowing tubes 24 can be inserted into the soil to achieve adjustment and control of the sowing depth. A mounting groove 17 that runs through the vehicle body 1 is provided, and the mounting groove 17 is slidably matched with the movable plate 18. A slide groove 20 is provided on the front and rear side walls of the mounting groove 17, and a slider 19 fixedly connected to the movable plate 18 is slidably installed in the two slide grooves 20. The rotating mounting groove on the vehicle body 1 A screw rod 21 is installed, and one end of the screw rod 21 is located in one of the slide grooves 20 and is threadedly connected to the corresponding slider 19. An adjusting knob 22 is fixedly installed on the top of the screw rod 21. Since the sowing tube 24 is installed at the bottom of the connecting plate 29 through the support rod 23, and the connecting plate 29 is installed at the bottom of the movable plate 18, before using the device, the initial position of the movable plate 18 on the vehicle body 1 can be adjusted by rotating the adjusting knob 22 and utilizing the cooperation between the screw rod 21 and the slider 19. The initial height of the multiple sowing tubes 24 relative to the ground can be adjusted. After that, the distance of the multiple sowing tubes 24 moving up and down each time remains unchanged, and the depth of their insertion into the soil can be controlled to achieve sowing treatment at different depths.

[0050] The movable plate 18 is provided with an insert assembly which cooperates with the connecting plate 29 and the blanking assembly. The insert assembly is composed of a fixed block 35, a reciprocating screw 36, an L-shaped rod 37, an active bevel gear 34 and a driven bevel gear 38. The fixed block 35 is fixedly mounted on the side wall of the movable plate 18, the reciprocating screw 36 is rotatably mounted on the fixed block 35, the L-shaped rod 37 is threadedly connected to the reciprocating screw 36, and the L-shaped rod 37 is fixedly connected to the connecting plate 29, the active bevel gear 34 is fixedly mounted on the end of the rotating shaft 30 away from the belt transmission structure 39, and the driven bevel gear 38 is fixedly mounted on the rotating shaft 30 away from the belt transmission structure 39. The driven bevel gear 38 is meshed with the driving bevel gear 34. When the rotating shaft 30 rotates, the reciprocating screw 36 is driven to rotate at the same time under the cooperation of the driving bevel gear 34 and the driven bevel gear 38. Then, the reciprocating screw 36 and the L-shaped rod 37 are cooperated to make the connecting plate 29 move up and down at the bottom of the moving plate 18. During the movement of the connecting plate 29, the sowing tube 24 can be driven to move up and down relative to the ground. When it moves down again, it can be inserted into the soil. By adjusting the transmission ratio of the driving bevel gear 34 and the driven bevel gear 38, the sowing tube 24 can be inserted into the soil. The reciprocating stroke of the reciprocating screw 36 and the L-shaped rod 37 is initially set, so that the incomplete gear 25 is separated from the fixed gear 27, so that the connecting plate 29 starts to move down, and when the incomplete gear 25 rotates half the angle of the missing tooth part relative to the fixed gear 27, the connecting plate 29 moves down to the maximum stroke, so that the blanking hole 33 on the blanking rod 32 is aligned with the position of the conveying pipe 14, thereby completing the sowing process at this time. In the subsequent process of the incomplete gear 25 rotating and meshing with the fixed gear 27 for the second time, the connecting plate 29 moves up and resets to prevent soil from adhering to the sowing pipe. The bottom of 24 causes subsequent crop seeds to be unable to fall smoothly. An air jet device can be set on the vehicle body 1, and a hose is used to connect the air jet device and the top of multiple sowing tubes 24. In addition, a touch switch for touching the air jet device is set on the top of the connecting plate 29. When the connecting plate 29 is moved up and reset, the touch switch is touched, so that the multiple hoses can use air to clean the sowing tubes 24 and spray off the soil attached to the bottom. The air jet device is an existing product, and the design of the hose and the electrical control of the touch switch box and the air jet device can all adopt existing technologies, so they are not elaborated here.

[0051] The guide block is fixedly installed on the side wall of the connecting plate 29 away from the L-shaped rod 37, and the bottom of the movable plate 18 is fixedly installed with a guide rod that slides with the guide block. Through the cooperation of the guide rod and the guide block, the moving direction of the connecting plate 29 can be effectively limited, so that it can move up and down stably relative to the movable plate 18. In order to prevent the sowing pipe 24 from moving down and contacting the ground during the travel of the equipment, the active bevel gear 34 can also be set as an incomplete bevel gear, and its diameter can be set to several times that of the driven bevel gear 38. At the same time, the angle of the toothed portion on the active bevel gear 34 is the same as the angle of the toothed portion on the incomplete gear 25. Through this design, after the incomplete gear 25 is separated from the fixed gear 27, the active bevel gear 34 and the driven bevel gear 38 are meshed and driven to rotate, thereby achieving the corresponding depth of planting processing when the equipment stops, and avoiding the problem of the sowing pipe 24 moving up and down during the travel of the equipment causing damage to itself or increasing the travel resistance of the equipment.

[0052] The compensation mechanism consists of a fixed rod, a T-rod, a T-slot and a spring. The fixed rod is fixedly mounted on the bottom of the driven bevel gear 38, and the T-rod is fixedly mounted on the bottom of the fixed rod. The T-slot is opened on the top side wall of the reciprocating screw 36, and the T-slot and the T-rod slide up and down together. The spring is installed between the T-rod and the T-slot. Since the initial height of the movable plate 18 on the vehicle body 1 needs to be adjusted at the beginning, and the height of the separation bucket 13 on the vehicle body 1 is fixed, when the height of the movable plate 18 is adjusted, there will be a height difference between the active bevel gear 34 and the driven bevel gear 38. At this time, the elastic force of the spring can be used to compensate for this height difference, thereby ensuring the meshing effect of the active bevel gear 34 and the driven bevel gear 38. At the same time, the cooperation of the T-rod and the T-slot can ensure the transmission effect between the fixed rod and the reciprocating screw 36.
