The lubricating grease box 10 is used for storing spindle lubricating grease special for the cotton picker.
In the process of using the lubricating device of the cotton picker, provided by the embodiment, the second hydraulic pump 3 pumps the hydraulic oil in the oil tank 1, the hydraulic oil pumped by the second hydraulic pump 3 sequentially flows through the electromagnetic valve 6 and the motor 82, and the on-off of the hydraulic oil path can be controlled by controlling the on-off of the electromagnetic valve 6, so as to control whether the hydraulic oil is supplied to the motor 82 or not, and control the on-off of the motor 82; in the rotating process, the motor 82 drives the first hydraulic pump 81 to rotate synchronously, and the first hydraulic pump 81 pumps the lubricating grease in the lubricating grease box 10 out to the cotton picking mechanism to lubricate the cotton picking mechanism.

Spindle lubricating grease on the market at present is uneven in quality, is likely to carry foreign matters and impurities, the working environment of a cotton picker is quite severe, foreign matters and impurities easily fall into the lubricating grease box 10 when spindle lubricating grease is injected, and therefore the lubricating grease filter 11 is of great importance to a cotton picking head lubricating system.
The pressure sensor is characterized by further comprising an alarm mechanism used for sending out alarm information when the pressure measured by the pressure sensor 13 is abnormal, wherein the alarm mechanism can be display equipment and used for displaying the alarm information when the pressure is abnormal, and can also be a buzzer or a warning lamp and is specifically determined according to actual conditions.

An oil inlet of the second hydraulic pump 3 is connected with an oil absorption filter 2; and/or an oil outlet of the motor 82 is connected with an oil return filter 9.
The oil absorption filter 2 can clean the hydraulic oil entering the second hydraulic pump 3 to protect the second hydraulic pump 3 and prolong the service life of the second hydraulic pump 3, and a filter with lower filtering precision is generally selected to prevent the oil absorption from being unsmooth.
A one-way valve 5 is connected between an oil outlet of the second hydraulic pump 3 and the electromagnetic valve 6; and/or an oil outlet of the second hydraulic pump 3 is connected with a safety valve 4, and an oil outlet of the safety valve 4 is connected with the oil tank 1.
The one-way valve 5 is arranged, so that hydraulic oil can be effectively prevented from flowing back to the second hydraulic pump 3, and impact on the second hydraulic pump 3 is avoided; the safety valve 4 may be an overflow valve to prevent damage to components due to excessive system pressure in abnormal situations.
In addition to the cotton picker lubricating device, the invention also provides a control method applied to the cotton picker lubricating device disclosed in the above embodiment, the control method comprising:
step S1, acquiring the oil pressure of a lubricating oil path measured by a pressure sensor 13;
step S2, judging whether the oil pressure of the lubricating oil way is in a preset range, and if so, controlling the motor 82 to normally operate; if not, the step S3 is executed;
s3, judging whether the oil pressure of the lubricating oil way is larger than or equal to the maximum value of a preset range, if so, controlling the electromagnetic valve 6 to lose power, stopping the motor 82 from rotating, and controlling the alarm mechanism to send out high-pressure warning information; if not, the step S4 is executed;
and S4, controlling the electromagnetic valve 6 to lose power, stopping the motor 82 from rotating, and controlling the alarm mechanism to send out low-voltage warning information.
In the specific control process, when the oil pressure of the lubricating oil way is detected to be greater than or equal to the maximum value of the preset range and lasts for the time T, the control solenoid valve 6 can be controlled to lose power, the motor 82 stops rotating, and the alarm mechanism is controlled to send out high-pressure warning information; when the oil pressure of the lubricating oil way is detected to be less than or equal to the minimum value of the preset range and the duration is 2T, the electromagnetic valve 6 is controlled to be powered off, the motor 82 stops rotating, and the alarm mechanism is controlled to send out low-pressure warning information. The reaction time for making the high-pressure warning is shorter than that for making the low-pressure warning, because the high-pressure warning is caused by the blocking of a lubrication point, the bending of a pipeline and other pressure-holding-up in general conditions, and if the duration is longer, parts and pipelines can be damaged; the low-pressure warning is mainly caused by lack of grease, little grease or filter blockage, and can not damage the system.
