Description
Technical field
The invention belongs to agricultural material transportation art, the device for transporting objects of harvest machinery is related specifically to.
Background technology
The device for transporting objects of current full feed type combined harvester is generally adopted by the structure of chain harrow form.In order to
The requirement of big feed quantity combining is adapted to, this chain harrow form conveying device is often designed to empty with larger floating
Between so that the device for transporting objects of harvest machinery has larger tolerance to material feed quantity, so when feed quantity is larger
When, material is not easy blockage problem in delivery chute.But the larger harvest machinery material conveying dress of this floating space
Put and also bring along new problem, i.e.,：Although delivery chute is not blocked when material feed quantity is larger, in subsequent threshing point
Serious blocking is there occurs from link.Now solve the problems, such as threshing separate link feed blocking will expend more times and
Energy.Therefore, production practices experience have shown that, the floating space of harvest machinery device for transporting objects is excessive to delay more on the contrary
Quality time and energy, be unfavorable for the raising of overall efficiency of crop.
The content of the invention
The present invention proposes a kind of self-adapting float formula harvest machinery device for transporting objects, purpose precisely in order to solving to receive at present
Obtain excessive the brought negative issue of mechanical device for transporting objects floating space so that conveying device has one to material feed quantity
While fixed width content, it is also possible to when feed quantity is excessive, separate link prior to follow-up threshing and block, now solve
The blockage problem that delivery chute feed blocking problem will separate link than solving threshing consumes less time and efforts, so that
Efficiency of crop is improved on the whole.
The technical solution adopted by the present invention is：In the combined harvester course of work, drive sprocket control execution unit is real-time
Receive the detection signal that photoelectric sensor and torque-measuring apparatus send, and judge sagging displacement and the drive sprocket of carrier chain
Torque value, drive sprocket control execution unit is judged according to built-in control program.If drive sprocket control execution unit inspection
Measure carrier chain sagging displacement exceed setting, but drive sprocket torque value in the reasonable scope, then drive sprocket control
Execution unit alarm driver carries out the work such as carrier chain tensioning, maintenance.If the torque value for detecting drive sprocket exceeds
Zone of reasonableness value, then drive sprocket control execution unit cut off drive sprocket input power immediately, with so that material delivery chute
Prior to the follow-up slight blocking of threshing and cleaning link generation or of short duration shut-down, reaching prompting driver reduces machine feed quantity or most
Early find and solve the problems, such as that material conveying is blocked.
Concrete scheme of the invention is：A kind of self-adapting float formula harvest machinery device for transporting objects, including driven sprocket,
Rake teeth, carrier chain, photoelectric sensor, drive sprocket, upper-lower casing and drive sprocket control execution unit.Driven sprocket and driving
Sprocket wheel is located in the cavity that upper-lower casing is formed, and driven sprocket is connected with drive sprocket by carrier chain, and rake teeth is uniformly arranged
On carrier chain.Torque-measuring apparatus, photoelectric sensor and torque-measuring apparatus are installed on the power input shaft of drive sprocket
It is connected with drive sprocket control execution unit.Photoelectric sensor is located at the lower section of upside carrier chain, and positioned at upside carrier chain
Sink deformation maximum, for detecting whether upside carrier chain sinks to maximum spacing place（That is photoelectric sensor position）.
In the combined harvester course of work, drive sprocket control execution unit real-time reception photoelectric sensor and torque-measuring apparatus send
Detection signal, and judge sagging displacement and the torque value of drive sprocket of carrier chain, drive sprocket control execution unit according to
Built-in control program is judged.If the sagging displacement that drive sprocket control execution unit detects carrier chain exceedes setting,
But the torque value of drive sprocket is in the reasonable scope, then drive sprocket control execution unit alarm driver carries out carrier chain
The work such as tensioning, maintenance.If detecting the torque value of drive sprocket beyond zone of reasonableness value, drive sprocket control execution unit
Cut off drive sprocket input power immediately so that material delivery chute prior to follow-up threshing and cleaning link occur it is slight block or
Of short duration shut-down, reaching prompting driver reduces machine feed quantity or finds as early as possible and solve the problems, such as that material conveying is blocked.
The benefit that the upside sprocket wheel spacing detection of sinking is carried out using photoelectric sensor is that mechanical contact can be avoided to trigger
The abrasion of device, has the advantages that low fault rate, simple structure and with low cost.
Brief description of the drawings
Shown in Fig. 1 is moderate fluctuation formula harvest machinery device for transporting objects front view of the present invention.
Shown in Fig. 2 is moderate fluctuation formula harvest machinery device for transporting objects photoelectric position limit detection part of the present invention
Partial enlarged drawing.
In figure：Driven sprocket 1, rake teeth 2, carrier chain 3, photoelectric sensor 4, drive sprocket 5, upper-lower casing 6, drive sprocket
Control execution unit 7.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, to specific embodiment of the invention（Such as dependency structure and
Its building form and action principle etc.）It is described in further detail.
As shown in Figure 1, moderate fluctuation formula harvest machinery device for transporting objects of the present invention includes driven sprocket 1, rake
The parts such as tooth 2, carrier chain 3, photoelectric sensor 4, drive sprocket 5, upper-lower casing 6 and drive sprocket control execution unit 7.Fig. 1
The dotted line of the lower section of middle carrier chain 3 represents the maximum sinking state of upside carrier chain in material conveying process.Wherein, it is desirable to photoelectric transfer
Sensor 4 is located at the maximum displacement that carrier chain 3 sinks, and maximum limit place value δ is no more than 15mm（Perpendicular to material conveying direction,
As shown in Figure 2）.
A kind of specific implementation process of moderate fluctuation formula harvest machinery device for transporting objects of the model is, main combined harvester
In the course of work, the detection letter that the drive sprocket control real-time reception photoelectric sensor 4 of execution unit 7 and torque-measuring apparatus send
Number, and judging the sagging displacement of carrier chain 3 and the torque value of drive sprocket 5, drive sprocket controls execution unit 7 according to built-in control
Processing procedure sequence is judged.If the sagging displacement that drive sprocket control execution unit 7 detects carrier chain 3 exceedes setting, but drives
In the reasonable scope, then the drive sprocket control alarm driver of execution unit 7 carries out carrier chain 3 to the torque value of movable sprocket 5
The work such as tensioning, maintenance.If detecting the torque value of drive sprocket 5 beyond zone of reasonableness value, drive sprocket control performs list
Unit 7 cuts off the input power of drive sprocket 5 immediately, so that material delivery chute occurs slight blocking up prior to follow-up threshing and cleaning link
Plug or of short duration shut-down, reaching prompting driver reduces machine feed quantity or finds as early as possible and solve the problems, such as that material conveying is blocked.
