It should be noted that, the oil tank 1 in the hydraulic oil path can store 46# antiwear hydraulic oil, and of course, according to different actual conditions, other types of hydraulic oil can be used; the lubricating oil way is mainly used for providing special spindle grease for each cotton picking head of the cotton picking mechanism, and the medium in the lubricating oil way is the special spindle grease.
The oil tank 1 is mainly used for storing and providing working medium for a hydraulic oil way, dissipates heat for a system during operation, and is positioned as close to the second hydraulic pump 3 as possible and is preferably higher than the second hydraulic pump 3; the second hydraulic pump 3 is a power element for providing pressure oil for the motor 82, and the second hydraulic pump 3 is a variable pump for simultaneously providing power sources for a plurality of executing elements of the cotton picker. The solenoid valve 6 controls the start of the lubricating oil circuit of the cotton picking head when power is supplied, and the solenoid valve 6 controls the stop of the lubricating oil circuit of the cotton picking head when power is lost.
The motor 82 is combined with the first hydraulic pump 81 as the grease motor pump 8, the motor 82 is an actuator of a hydraulic oil passage, the first hydraulic pump 81 is a power element of a lubrication oil passage, and the motor 82 is coaxially connected with the first hydraulic pump 81. The grease box 10 is used for storing spindle grease specially used for cotton picker.
In the process of using the lubricating device of the cotton picker provided by the embodiment, the second hydraulic pump 3 pumps out the hydraulic oil in the oil tank 1, the hydraulic oil pumped out by the second hydraulic pump 3 sequentially flows through the electromagnetic valve 6 and the motor 82, and the on-off of a hydraulic oil way can be controlled by controlling the on-off of the electromagnetic valve 6 so as to control whether to provide the hydraulic oil for the motor 82 or not, thereby controlling the start and stop of the motor 82; the motor 82 drives the first hydraulic pump 81 to synchronously rotate in the rotating process, and the first hydraulic pump 81 pumps out the lubricating grease in the lubricating grease box 10 to the cotton picker mechanism to lubricate the cotton picker mechanism.
Compared with the prior art, the hydraulic driving control mode has high reliability and less influence by severe environment compared with the electric control mode in the prior art by controlling the action of the first hydraulic pump 81 in the lubricating oil path through the motor 82 in the hydraulic oil path, and the stability of the lubricating device of the cotton picker under severe working conditions can be effectively improved; the working condition that the cotton picker is used as a walking compact type machine for multiple actions is met.
In a specific embodiment, the outlet of the first hydraulic pump 81 is connected with a main multi-way block 12 and a pressure sensor 13, the main multi-way block 12 is provided with a plurality of oil outlets, one of the oil outlets is connected with the pressure sensor 13, and the rest of the oil outlets are arranged in one-to-one correspondence with a plurality of cotton picking heads of the cotton picking mechanism; the main multi-way block 12 is used for conveying lubricating grease to the cotton picking head, and the pressure sensor 13 is used for measuring the pressure at the oil outlet of the main multi-way block 12.
As shown in fig. 1, a grease filter 11 is disposed between the outlet of the first hydraulic pump 81 and the main multi-way block 12, and the grease filter is configured to filter foreign matter impurities in grease to prevent blocking the lubrication channel and protect the cotton picking head rotating member from damage. The quality of spindle lubricating grease on the current market is uneven, foreign matter impurities are likely to be carried by the spindle lubricating grease, meanwhile, the working environment of a cotton picker is very bad, and the foreign matter impurities are easy to fall into the lubricating grease box 10 when the spindle lubricating grease is filled, so that the lubricating grease filter 11 is very important for a cotton picking head lubricating system.
The pressure sensor 13 is used for measuring pressure of the air, and the pressure sensor 13 is used for detecting pressure of the air, and also comprises an alarm mechanism used for sending out alarm information when the pressure measured by the pressure sensor is abnormal, wherein the alarm mechanism can be display equipment and can also be a buzzer or a warning lamp when the pressure is abnormal, and the alarm mechanism is determined according to actual conditions.
As shown in fig. 1, the main multi-pass block 12 is used for distributing clean grease passing through the grease filter 11 to six cotton picker heads, here, taking six rows of horizontal spindle cotton picker as an example, and simultaneously, one oil port is reserved for the pressure sensor 13 as a detection port; the pressure sensor 13 is used for monitoring the pressure of a main oil way in the cotton picking head lubrication system, transmitting a pressure signal to the controller, and setting a reasonable preset range by a control program, so that once the preset range is exceeded, alarm information can be displayed on the airborne display equipment, and the quick detection and the quick fault solving can be realized.
In this embodiment, when the pressure measured by the pressure sensor 13 is within the preset range, the motor 82 is controlled to rotate normally, and when the pressure measured by the pressure sensor 13 is greater than or equal to the maximum value of the preset range, the electromagnetic valve 6 is controlled to be powered off, the motor 82 is controlled to stop rotating, and the alarm mechanism is controlled to send out high-voltage alarm information; when the pressure measured by the pressure sensor 13 is smaller than or equal to the minimum value of the preset range, the electromagnetic valve 6 is controlled to be powered off, the motor 82 is controlled to stop rotating, and the alarm mechanism is controlled to send out low-pressure alarm information.
Compared with the prior art, the pressure sensor 13 in this embodiment can measure the pressure of the main oil path in the lubricating oil path in real time, and combine with the related controller, and timely make related reaction when the measured pressure does not meet the requirement, so as to avoid insufficient lubrication and abrasion.
The main multi-way block 12 is connected with a branch multi-way block 14, the branch multi-way block 14 is provided with a plurality of oil outlets and throttle valves 15 which are arranged in one-to-one correspondence with the oil outlets, and the throttle valves 15 are used for controlling the oil outlet flow of the oil outlets of the corresponding branch multi-way block 14.
The effect of the combination of the shunt multi-pass block 14 and the throttle valve 15 is: the six lubrication points of the front and rear cam tracks of the cotton picking head, the front and rear cotton picking head transmission assembly and the front and rear dummy bar seat tube assembly are lubricated, and due to the fact that the lubrication demand of the six lubrication points is different, the throttle valve 15 integrated on the branching multi-pass block 14 can be adjusted to obtain proper grease output, so that the lubrication is really realized on demand, the defects caused by insufficient lubrication and excessive lubrication are avoided, the cost is saved, and the waste is prevented.
The branching multi-way block 14 is connected with an oil cup 16 which can be used for manual lubrication; under special conditions, when the lubricating device of the cotton picker cannot work normally but has a lubricating requirement, the normal operation of the cotton picker can be temporarily not delayed by manual lubrication.
In a specific embodiment, a hydraulic damper 7 is connected between the solenoid valve 6 and the motor 82, and the hydraulic damper 7 is used to adjust the flow rate of hydraulic oil entering the motor 82 to adjust the rotation speed of the motor 82.
In this embodiment, when the lubrication electromagnetic valve 6 is powered on, the flowing hydraulic oil will generate a pressure difference through the damping hole of the hydraulic damper 7, so as to control the flow entering the motor 82, and different rotational speeds of the motor 82 can be obtained by matching with the hydraulic damper 7 with different specifications, so that the flow of the lubrication device of the cotton picker is indirectly controlled from the source.
An oil inlet of the second hydraulic pump 3 is connected with an oil suction filter 2; and/or an oil outlet of the motor 82 is connected with an oil return filter 9.
The oil suction 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, wherein a filter with lower filtering precision is generally selected for preventing unsmooth oil suction.
A one-way valve 5 is connected between the oil outlet of the second hydraulic pump 3 and the electromagnetic valve 6; and/or the oil outlet of the second hydraulic pump 3 is connected with a safety valve 4, and the oil outlet of the safety valve 4 is connected with the oil tank 1.
The arrangement of the check valve 5 can effectively prevent the hydraulic oil from flowing back to the second hydraulic pump 3 and avoid the impact on the second hydraulic pump 3; the relief valve 4 may be an overflow valve to prevent damage to components due to excessive system pressure in the event of an abnormal situation.
In the process of using the cotton picker lubricating device, the control method comprises the following steps:
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 within a preset range, if so, controlling the motor 82 to normally operate; if not, entering step S3;
step S3, judging whether the oil pressure of the lubricating oil way is greater than or equal to the maximum value of a preset range, if so, controlling the electromagnetic valve 6 to lose electricity, controlling the motor 82 to stop rotating, and controlling the alarm mechanism to send out high-pressure alarm information; if not, entering step S4;
and S4, controlling the electromagnetic valve 6 to be powered off, stopping the motor 82 from rotating, and controlling the alarm mechanism to send out low-voltage alarm 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 the duration time T is detected, the electromagnetic valve 6 can be controlled to be powered off, the motor 82 is controlled to stop rotating, and the alarm mechanism is controlled to send out high-pressure alarm information; when the oil pressure of the lubricating oil path is detected to be smaller than or equal to the minimum value of the preset range and lasts for 2T, the electromagnetic valve 6 is controlled to be powered off, the motor 82 is controlled to stop rotating, and the alarm mechanism is controlled to send out low-pressure alarm 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 blocking a lubricating point position, bending a pipeline and the like under normal conditions, and if the duration is longer, the parts and the pipeline can be damaged; the low-pressure warning is mainly caused by fat deficiency, fat deficiency or filter blockage, and cannot damage the system.
The "first" and "second" in the first hydraulic pump 81 and the second hydraulic pump 3 are mentioned in this specification only for distinguishing the difference in position, and are not sequentially separated.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
