AI Technical Summary
The existing air-suction seeder has a complex mechanical transmission structure, which leads to unstable wind force, making it easy for seeds to fall off and be missed. In addition, it requires readjustment when turning, which affects the efficiency of operation.
The electric suction seeder adopts an integrated power output harness, including a main harness and branch harnesses. Each seed meter is driven by a separate electric fan. It is equipped with an overcurrent fuse and a power switch audible and visual alarm control box to achieve stable power control.
This ensures consistent airflow for each seed metering unit, preventing seed drop and missed sowing, improving sowing stability and efficiency, and reducing the failure rate.

Abstract
Description
Technical Field
[0001] This utility model relates to the power system of a pneumatic seeder, and in particular to an integrated wiring harness for the power output of an electric suction seeder. Background Technology
[0002] Existing pneumatic seeders rely on an axial fan driven by a universal joint shaft connected to the tractor's power take-off shaft, resulting in a complex structure. This structure is affected by the tractor's power; for example, the airflow fluctuates depending on the engine throttle; airflow is interrupted by tractor gear shifting; and the carrying structure (requiring the tractor's hydraulic suspension system to lift the seeder more than 40 cm off the ground when turning at the end of the field) can cause power output to be interrupted if the angle is too large, leading to the fan stopping, interrupting airflow, and causing seeds to fall from the seed tray. Even in towed operations, the engine can only idle during turns, causing the fan to stop or the airflow from the seed tray to decrease, resulting in all seeds falling to the ground. Furthermore, the turning radius cannot be too small, otherwise the universal joint shaft will exceed its transmission angle, damaging transmission components or the fan. After turning, the seeder needs to travel a certain distance again for the seed tray to re-absorb seeds before normal sowing can resume, leading to missed sowing and seed waste. Furthermore, due to the length of the suction pipe, each of the 2nd to 12th rows of the seeder needs to be connected to a suction port through a pipe, resulting in inconsistent airflow for each seed metering device. The further away the seed metering device is from the fan, the longer the pipe and the weaker the airflow.
[0003] In view of the above, this utility model is hereby proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an integrated wiring harness for the power output of an electric suction seeder.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is: an integrated wiring harness for the power output of an electric seeder, including a main wiring harness and branch wiring harnesses. The input end of the main wiring harness is connected to the generator of the tractor that drives the seeder, and the output end of the main wiring harness is connected to the input end of the branch wiring harness. The number of branch lines at the output end of the branch wiring harness is determined by the number of seeding rows of the seeder.
[0006] Preferably, each branch line at the output end of the branch harness is connected to an electric fan.
[0007] Preferably, the main harness is provided with a main harness overcurrent protection device, and each branch line of the branch harness is provided with a branch harness overcurrent protection device.
[0008] Preferably, the main wiring harness is also equipped with a power switch audible and visual alarm control box.
[0009] Preferably, it also includes a fan control device that can individually control the start and stop of each fan.
[0010] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: it solves the problems of complex structure and defects in the use of existing mechanical transmission fans, realizes that each seed metering device is picked up by a separate electric fan, this utility model makes the power more stable, the wind force is consistent, and there will be no seed drop or missed sowing, which can save seeds. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the integrated wiring harness for the power output of an electric seeder with six branch lines.
[0012] In the diagram: 1-Main harness overcurrent protection device, 2-Power switch audible and visual alarm control box, 3-Main harness, 4-Branch harness, 5-Branch harness overcurrent protection device. Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to help to understand the content of the present invention.
[0014] like Figure 1 As shown, this utility model is a tractor power output integrated wiring harness specifically for electric fan air suction seeders, including a main wiring harness 3, a main wiring harness overcurrent fuse device 1, branch wiring harnesses 4, branch wiring harness overcurrent fuse devices 5, and a power switch audible and visual alarm control box 2. This utility model uses the tractor generator's power output to enable the electric fan to pick up seeds. The wiring harness is designed based on the power consumption of each generator per row (200-240 watts) and the voltage drop generated during power transmission, with a single electric fan wire carrying capacity of 12-20A per row. Each branch wire uses 4 square millimeter anti-freeze and anti-aging multi-core copper wire, and an overcurrent fuse device is installed on the positive terminal of each branch wire. The main wiring harness 3 is designed according to the number of electric fans multiplied by the cross-sectional area of the branch wires (a 6-row seeder uses 6 electric fans, each row of electric fans has a 4 square millimeter branch wire, i.e., the main wiring harness 3 is 6*4=24 square millimeters). The main wiring harness 3 is also connected to an overcurrent fuse and is equipped with a power switch audible and visual alarm control box 2, which has a built-in main power switch and a voltage monitoring audible and visual alarm device. It displays the voltage value of the main wiring harness 3 in real time. When the voltage value is higher or lower than the set voltage range, the audible and visual alarm system is activated, emitting a beeping sound and flashing a warning light. This invention also includes a fan control device, which can individually control the start and stop of each fan to adapt to different sowing row spacings and increase adaptability.
[0015] This utility model is connected to a tractor generator, providing stable and controllable power output to the seeder and driving each electric fan, ensuring continuous and stable wind power. It eliminates the problem of wear on mechanical transmission parts, has a simple structure, is easy to operate, and has a low failure rate. All power output parts are equipped with voltage monitoring, overcurrent protection, and overload protection devices, ensuring extremely high safety.
[0016] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
