Description

Technical Field

[0001] The invention relates to a harvester device, more specifically, to an automatic dust removal control system for a radiator of a rice and wheat combine harvester. Background Art

[0002] The working environment of rice and wheat combine harvesters is harsh and dusty. In particular, dust accumulated on the radiator fins will affect the heat dissipation of the engine and thus the engine performance. What's worse, dust can cause engine failure and damage.

[0003] There are currently two dust removal solutions for rice and wheat combine harvesters on the market. First, adding a rotating brush to the radiator shell to clean the external dust can only treat the symptoms but not the root cause. Second, the engine cooling fan is reversed regularly to blow away the dust accumulated on the heat sink. Due to uneven airflow, the edges are not cleaned cleanly, and the dust cannot be automatically removed according to the operating conditions. Summary of the invention

[0004] Based on this, it is necessary to provide an automatic dust removal control system for a radiator of a rice-wheat combine harvester in response to the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A radiator automatic dust removal control system for a rice-wheat combine harvester, characterized in that the radiator automatic dust removal control system for a rice-wheat combine harvester comprises a radiator, a U-shaped guide rail bracket is provided on one side of the radiator, an annular guide rail is provided on the inner wall of the guide rail bracket, a pair of movable guide rail seats are provided on the guide rail, and a detachable fan assembly is provided on the guide rail seat. The fan assembly moves around in a 360° manner on the guide rail bracket. The automatic dust removal control system for the radiator of the rice and wheat combine harvester also includes a control handle, a controller and a display screen. The controller controls the guide rail seat and the fan assembly.

[0006] As a preferred embodiment of the present invention, a plurality of dust sensors are provided on the side wall of the radiator.

[0007] As a preferred embodiment of the present invention, the dust sensor is an ultra-thin laser dust sensor.

[0008] As a preferred embodiment of the present invention, a plurality of cameras are provided on the guide rail bracket.

[0009] As a preferred embodiment of the present invention, the fan assembly includes a fan side panel, on which a fan, an air guide hood and a soft brush roller are arranged, and on which an adjusting motor is arranged, which drives the air guide hood and controls the air outlet direction of the air guide hood.

[0010] As a preferred embodiment of the present invention, the fan is an axial flow fan.

[0011] A method for automatically controlling dust removal of a radiator for a rice-wheat combine harvester, using the automatic dust removal control system for a radiator for a rice-wheat combine harvester as described above, comprises the following steps: Step S1, the dust sensor detects the dust density on the surface of the radiator in real time. When the dust density reaches a higher preset PM value, the controller recognizes the signal and starts the dust removal operation; Step S2, the controller controls the guide rail seat to move the fan assembly to a suitable position, starts the fan assembly, and the fan of the fan assembly starts to work, and the motor is adjusted to control the air outlet direction of the guide air cover, and the soft brush roller brushes the dust on the surface of the radiator at the same time; Step S3: When the dust sensor detects that the dust density on the surface of the radiator is lower than a preset PM value, the fan assembly is stopped and returned to its original position.

[0012] As a preferred embodiment of the present invention, the fan assembly includes three working modes: a horizontal working mode, a longitudinal working mode and a 360° surround motion mode.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an automatic dust removal control system for a radiator of a rice-wheat combine harvester. The automatic dust removal control system for a radiator of a rice-wheat combine harvester can automatically identify the working environment, effectively remove dust from the radiator, always keep the heat sink of the radiator at a relatively clean level, effectively improve the performance of the engine, and achieve a certain energy-saving and emission reduction effect under working conditions with less dust.
