Description

Technical Field

[0001] This utility model relates to the field of wheat seed dressing technology, and in particular to a seed dressing device for wheat planting. Background Technology

[0002] To ensure wheat yield and quality, farmers need to take measures to control pests and diseases and improve wheat's resistance to adverse conditions during wheat planting. Among these measures, seed treatment and pesticide spraying are common agricultural management practices. Seed treatment can improve the germination rate and resistance to pests and diseases by adding seed treatment agents, biological agents, etc. to wheat seeds, thereby increasing wheat yield and quality. Seed treatment requires the use of a seed treatment device.

[0003] However, existing seed coating devices have the following drawbacks: Firstly, the drive motor is typically located at the bottom of the coating tank, with internal spiral stirring blades. However, the solution needs to be added manually and slowly during the mixing process, increasing labor intensity and resulting in uneven mixing. Secondly, after the solution and seeds are mixed, the solution on the seed surface is not completely dry, requiring additional drying, which affects overall processing efficiency. Therefore, further improvements are needed. To address this, we propose a seed coating device for wheat cultivation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seed-mixing device for wheat planting.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a seed mixing device for wheat planting is disclosed, comprising a base plate 1, multiple support rods 2 fixed to the side of the upper surface of the base plate 1, a top plate 3 fixedly connected to the top of the multiple support rods 2, a cylinder 4 through and fixed in the middle of the top plate 3, a mixing assembly 5 inside the cylinder 4, a horizontal plate 6 fixed to the top of the cylinder 4, a vertical pipe 7 through and rotatably connected to the middle of the horizontal plate 6 via a bearing, a medicine hopper 9 connected to the top of the vertical pipe 7, a bent medicine discharge pipe 8 fixedly connected to the side wall of the bottom end of the vertical pipe 7, a motor 10 for driving the vertical pipe 7 to rotate installed on the upper surface of the horizontal plate 6, a hot air assembly installed on the upper surface of the top plate 3, a conical bottom design for the cylinder 4, and a bottom cover 13 rotatably connected to the bottom of the cylinder 4 via a hinge, and a controller installed on the upper surface of the base plate 1.

[0022] In this embodiment, the controller adopts a PLC programmable controller, specifically the Siemens SIMATIC KP1200 series controller with screen (HMI+PLC integrated machine). The controller controls the operation of motor 10 and hot air assembly. The specific electrical connection methods all adopt existing technologies, which will not be described in detail here.

[0023] The medicine hopper 9 is fixed to the upper surface of the horizontal plate 6 by a vertical rod. A medicine discharge pipe 91 is fixed to the bottom of the medicine hopper 9. A control valve 92 is fixed in the middle of the medicine discharge pipe 91. The bottom of the medicine discharge pipe 91 is rotatably connected to the vertical pipe 7 through a sealed bearing.

[0024] In this embodiment, the control valve 92 is a manual valve. After adding medicine into the medicine hopper 9, the medicine is discharged along the medicine discharge pipe 91, enters the medicine discharge pipe 8 through the vertical pipe 7, and is sprinkled on the seed surface through the medicine discharge pipe 8. The dispensing speed can be controlled by controlling the opening and closing degree of the control valve 92.

[0025] A drive bevel gear 101 is fixed at the output end of the motor 10, and a driven bevel gear 71 is fixed on the top surface of the vertical tube 7. The drive bevel gear 101 and the driven bevel gear 71 mesh.

[0026] By starting the motor 10, the active bevel gear 101 is driven to rotate, which in turn drives the driven bevel gear 71 to rotate, thereby driving the vertical tube 7 to rotate. The discharge pipe 8 on the surface of the vertical tube 7 will also rotate, so that the discharged liquid can be evenly sprinkled on the surface of the seeds inside the cylinder 4, improving the mixing efficiency.

[0027] The stirring assembly 5 includes a vertical shaft 51 fixed to the bottom end of the vertical tube 7, and a spiral stirring blade 52 is fixedly connected to the surface of the vertical shaft 51.

[0028] When the vertical tube 7 is driven to rotate by the motor 10, the vertical tube 7 will also drive the vertical shaft 51 to rotate synchronously, thereby driving the spiral stirring blade 52 to rotate, and using the spiral stirring blade 52 to stir the seeds.

[0029] The hot air assembly includes a fan 11 fixedly installed on the lower surface of the top plate 3. The air outlet of the fan 11 is fixedly connected to an air duct 12, which is connected to the side wall of the cylinder 4. An electric heating wire is installed inside the air duct 12.

[0030] In this embodiment, both the blower 11 and the electric heating wire are electrically connected to the controller. After the blower 11 is started, air is blown upwards onto the cylinder 4 through the air duct 12. When the air passes through the air duct 12, it is heated by the electric heating wire inside. The hot air dries the seeds above the cylinder 4, thus drying the medicine.

[0031] An electric telescopic rod 14 is hinged to the upper surface of the base plate 1, and the top telescopic end of the electric telescopic rod 14 is hinged to the lower surface of the bottom cover 13.

[0032] When the mixing is complete and the seeds inside the cylinder 4 need to be discharged, the electric telescopic rod 14 is activated to shorten. The electric telescopic rod 14 pulls the bottom cover 13 to rotate around the hinge, thereby opening the bottom of the cylinder 4 and allowing the seeds to be discharged from the bottom of the cylinder 4.

[0033] Working principle: After adding seeds into the cylinder 4, add medicine into the medicine hopper 9. The controller starts the motor 10 and the fan 11 and electric heating wire of the hot air assembly. The motor 10 drives the active bevel gear 101 to rotate. The active bevel gear 101 drives the driven bevel gear 71 to rotate the vertical tube 7. The vertical tube 7 drives the bottom vertical shaft 51 and the spiral stirring blade 52 to stir the seeds. At the same time, the vertical tube 7 drives the discharge pipe 8 to rotate. At this time, the control valve 92 at the bottom of the medicine hopper 9 is opened. The medicine enters the vertical tube 7 through the discharge pipe 91 and is evenly sprinkled onto the seeds through the rotating discharge pipe 8. The fan 11 of the hot air assembly blows air into the air pipe 12. After being heated by the electric heating wire, the hot air enters the cylinder 4 through the air pipe 12 to dry the mixed seeds. After stirring is completed, the controller starts the electric telescopic rod 14 to shorten the electric telescopic rod 14 and pull the bottom cover 13 to rotate around the hinge to open the bottom of the cylinder 4 and discharge the seeds.
