Description

Technical Field

[0001] The invention relates to a power system of an air suction seeder, in particular to a power output integrated wiring harness of an electric suction seeder. Background Art

[0002] The air force of the existing air suction seeder comes from the axial flow fan driven by the universal transmission shaft connected to the tractor power output shaft, and the structure is complex. This structure will be affected by the tractor power, such as the wind force fluctuating due to the size of the engine throttle; the wind force will be interrupted due to the tractor shifting operation; affected by the carrying structure (when turning at the end of the field during sowing operations, the tractor hydraulic suspension system needs to be used to lift the seeder more than 40 cm off the ground), when the angle is too large when the seeder is lifted, the power output is forced to be interrupted, the fan stops working, the wind force is interrupted, and the seeds on the seeding plate fall off. Even for traction operations, the engine can only work at idle speed during the turning process, which will cause the fan to stop or the wind force of the seeding plate to drop, and all the seeds will fall to the ground; at the same time, the turning radius cannot be too small, otherwise the universal transmission shaft will exceed the transmission angle, damage the transmission components or the fan, and after turning, it is necessary to drive a distance again to allow the seeding plate to re-absorb the seeds before normal sowing operations can be performed, so there will be problems of missed sowing and wasted seeds. And affected by the length of the suction pipe, the 2nd to 12th rows of the seeder need to be connected to an air suction port through a pipe, so that the wind force of each seeding device is inconsistent. The farther the seeding device is from the fan, the longer the pipe is and the smaller the wind force is.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an integrated wiring harness for power output of an electric suction seeder.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: an integrated wiring harness for power output of an electric suction seeder, comprising a main wiring harness and a branch wiring harness, the input end of the main wiring harness is connected to the tractor generator that drives the seeder, the output end of the main wiring harness is connected to the input end of the branch wiring harness, and the number of branch lines at the output end of the branch wiring harness is determined by the number of sowing rows of the seeder.

[0006] Preferably, each branch line at the output end of the branch line bundle is connected to an electric blower.

[0007] Preferably, the main wiring harness is provided with a main wiring harness overcurrent protection device, and each branch wire of the branch wiring harness is provided with a branch wiring harness overcurrent protection device.

[0008] Preferably, a power switch sound and light alarm control box is also provided on the main wiring harness.

[0009] Preferably, it also includes an electric fan control device, which can individually control the start and stop of each electric fan.

[0010] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: it solves the problems of complex structure of the existing mechanical transmission fan and defects generated during use, and realizes that each seed meter is taken out by a separate electric fan. The present invention makes the power more stable, the wind force remains consistent, and there will be no seed loss or omission, which can save seeds. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In the figure: 1-main wiring harness overcurrent protection device, 2-power switch sound and light alarm control box, 3-main wiring harness, 4-branch wiring harness, 5-branch wiring harness overcurrent protection device. DETAILED DESCRIPTION

[0013] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention.

[0014] like Figure 1 As shown, the present invention is a tractor power output integrated wiring harness dedicated to an electric fan air suction seeding machine, including a main wiring harness 3, a main wiring harness overcurrent protection device 1, a branch wiring harness 4, a branch wiring harness overcurrent protection device 5 and a power switch sound and light alarm control box 2 and other components. The present invention uses the power output of the tractor generator to realize the electric fan seeding. The wiring harness is designed based on the power consumed by each generator power (200-240 watts) in each row, and the voltage drop generated during the power transmission process. The current carrying capacity of a single electric fan wire in a single row is 12-20A. Each branch line uses a 4-square antifreeze and anti-aging multi-core copper wire, and an overcurrent protection device is installed on the positive line of each branch line. The main wiring harness 3 is designed according to the number of electric fans multiplied by the square of the branch line (a 6-row seeding machine uses 6 electric fans, and each row of electric fans has a 4-square branch line, that is, the main wiring harness 3 is 6*4=24 square). The main wiring harness 3 is also connected to an overcurrent protection device, and is provided with a power switch sound and light alarm control box 2, which has a built-in main power switch and a voltage monitoring sound and light alarm device, and 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 sound and light alarm system starts, emits a beeping sound and flashes a warning light. The present invention also includes an electric fan control device, which can control the start and shut down of each electric fan separately to adapt to different sowing row spacings and increase adaptability.

[0015] The present invention is connected to a tractor generator, has stable power, and can be output to a seed drill in a controllable manner to drive each electric fan, thereby ensuring continuous and stable wind power without the problem of wear of mechanical transmission parts. The invention has a simple structure, is easy to operate, and has a low failure rate. All power output parts are provided with voltage monitoring, overcurrent protection, overload protection and other devices, and have extremely high safety.

[0016] The above is only 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 principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
