Abstract
The utility model discloses a combine harvester, which comprises a header and a control system for controlling the lifting of the header, wherein the control system comprises an oil cylinder for driving the header to lift, an operating mechanism for controlling a piston rod of the oil cylinder to stretch, and a sensor and a monitor which are collecting the stretching amount of the piston rod; the operating mechanism comprises a manual valve connected with the oil cylinder in a control mode; the monitor comprises a controller; the input sampling end of the controller is connected with the signal output end of the sensor; and the output control end of the controller is connected with a display for displaying the acquisition information of the sensor. According to the combine harvester, drivers can know the lifting height of the header by the display, and when the piston rod of the oil cylinder is contracted due to the internal leakage of a gear pump and a reversing valve, the drivers operate the manual valve according to the change of numerical values on the display to control the lifting of the header, so the height of the header is ensured.
Description
Technical field
The utility model relates to the combine technical field, is specifically related to the control system of combine harvester cutting table.
Background technology
The effect of combine harvester cutting table is to be transported to the shelling part with the crop cutting and with the crop of cutting off; The existing ceding of Taiwan is supported through oil cylinder; Thereby and by the up-down of the control stick in the control room, to adapt to cutting height and ground crack requirement through the flexible control ceding of Taiwan of HYDRAULIC CONTROL SYSTEM oil cylinder.The cutting height of combine is to influence harvesting work quality and efficient key factor, generally at 100～150mm.Because reasons such as the plot are uneven, and alley is more, ceding of Taiwan deadweight is bigger in addition; When letting out in gear pump, the reversal valve; The piston rod of oil cylinder stretches out and causes ceding of Taiwan meeting slowly to descend, and these have all directly influenced cutting height, and sight line is poor when gathering in especially at night; The driver does not see ceding of Taiwan terrain clearance and the ceding of Taiwan fallen in the tram influence the harvesting effect, and influences operating efficiency.
The utility model content
The purpose of the utility model provides a kind of combine that can effectively control the taiwan cut off and landing height, causes the ceding of Taiwan to descend because of the piston rod of oil cylinder stretches out influence the problem of gathering in effect in order to solve the driver.
The combine of the utility model adopts following technical scheme: a kind of combine; Comprise the ceding of Taiwan and be used to control the control system of taiwan cut off and landing; Said control system comprises the oil cylinder and the flexible operating mechanism of piston rod that is used to control oil cylinder that is used to drive taiwan cut off and landing; Said operating mechanism comprises the hand-operated valve with the oil cylinder control connection, and said control system also comprises sensor and the monitor that is used to gather the piston rod stroke, and said monitor comprises a controller; Controller input sample end links to each other with the signal output part of said sensor, and the controller output control terminal is used to show that with one the display of sensor acquisition information links to each other.
Said sensor is a magnetic induction sensor, and the end of said oil cylinder piston bar is fixed with the magnet that cooperates with said magnetic induction sensor induction.
Said operating mechanism also comprises and the magnetic valve of said oil cylinder control connection and change-over switch, said magnetic valve and the said controller control connection that realizes the on off operating mode conversion of magnetic valve or hand-operated valve and oil cylinder.
Adopt the combine of said structure, the control system of this grain header comprises and is used to gather the sensor of oil cylinder piston bar stroke and be located at the monitor in the control room that this monitor comprises controller; The controller input sample connects sensor signal output, output control connection display; Through the signal of controller record sensor acquisition oil cylinder stroke, and be presented on the display, because the adjustable height of the ceding of Taiwan is consistent with the stroke of oil cylinder with numerical value; Therefore; Just can understand the adjustable height of the ceding of Taiwan through display, in gear pump, reversal valve occur, let out when causing the oil cylinder piston bar to shrink, the driver is according to the operation of the numerical value change on display hand-operated valve; The control ceding of Taiwan is risen, and guarantees the height of the ceding of Taiwan.

Embodiment
The embodiment of the combine of the utility model: as shown in Figure 1; Comprise the control system that the ceding of Taiwan 1 and the control ceding of Taiwan 1 are gone up and down; This control system comprises the flexible operating mechanism of oil cylinder 4 that drives taiwan cut off and landing and the piston rod of controlling oil cylinder 4; Said operating mechanism comprises the hand-operated valve 5 that is connected with oil cylinder 4 through oil circuit, thereby the piston rod of the break-make control oil cylinder 4 through the action bars in operating room control hand-operated valve 4 is flexible, and this partial content is a technology as well known to those skilled in the art.Said control system also comprises magnetic induction sensor 2 and monitor of the piston rod stroke that is used to gather oil cylinder 4; During concrete operations; Said magnetic induction sensing 2 devices are fixed on the outer wall of oil cylinder 4; The fixing magnet that cooperates with said magnetic induction sensor 2 inductions of the piston-rod end of oil cylinder 4, said monitor comprises the controller (not shown), controller input sample end links to each other with the signal output part of magnetic induction sensor 2; The output control terminal of controller links to each other with a display 3; Piston rod drives magnet and moves in telescopic process, magnetic induction sensor 2 is recorded in the change in location of the magnet of induction in the controller with electrical signal form, and controller is presented on the display 3 with the form of numerical value again.
In the foregoing description; Said operating mechanism also comprises the magnetic valve (not shown) that is connected with oil cylinder 4 through oil circuit; Said magnetic valve is connected with controller, and controller can be controlled the break-make of magnetic valve through the change in location of magnet, thereby control oil cylinder 4 is flexible.For the control that makes magnetic valve and hand-operated valve 5 is independent of each other; Said operating mechanism also comprises an oil circuit change-over switch (not shown); This oil circuit change-over switch is used to control magnetic valve or hand-operated valve 5 is changed with the oil circuit break-make of oil cylinder 4, i.e. magnetic valve unloading during hand-operated valve 5 work, hand-operated valve 5 unloadings during magnetic valve work; This partial content is a technology as well known to those skilled in the art, gives unnecessary details no longer in detail.In other embodiments, also magnetic valve can be set.
The foregoing description is when operation, and the driver makes the magnetic valve unloading at the operation in-house operation change-over switch of combine, promotes control stick forward; The piston rod of oil cylinder 4 stretches out; The ceding of Taiwan 1 is risen, otherwise descends, and the height that the ceding of Taiwan 1 is gone up and down is consistent with the stroke of the piston rod of oil cylinder 4 all the time; Magnetic induction sensor 2 is presented at the piston rod stroke of oil cylinder 4 on the display 3 with the numerical value form through controller, and the driver just can adjust the height of the ceding of Taiwan 1 through the numerical value on the display 3.Automatically shrink when causing the ceding of Taiwan 1 to descend when piston rod appears in oil cylinder 4, the driver can rise the ceding of Taiwan according to the numerical value change operating operation bar of display 3; Also can be behind the good ceding of Taiwan 1 height of manual adjustment, the operation change-over switch makes hand-operated valve 5 unloadings, and controller is according to the overhang control magnetic valve of piston rod, and magnetic valve is controlled the ceding of Taiwan 1 automatically and is risen.
