Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
nullAs depicted in figs. 1 and 2,Described circular baler net chute installation,It is arranged on inside the bundling house of circular baler,It is provided with in bundling house by organizing the bundled room of circle 11 that rotating pressure roller forms more,Described circular baler net chute installation includes storing up net roller 20、Tension-adjusting gear、Master draws net roller 40、Drive motor 50、Belt wheel 51、Support roller 60、Cut net device,It is wound with silk screen 70 on described storage net roller 20,Described tension-adjusting gear includes hold-down roller 31、Connecting rod 32、Fixed arm 33、Spring 34、Hand arm 35,Fixed arm 33 is mutually perpendicular to the central shaft of hold-down roller 31 and the central shaft of the tail end of fixed arm 33 and hold-down roller 31 is fixing is connected,One end of connecting rod 32 is hinged with the central shaft of hold-down roller 31,The other end of connecting rod 32 is hinged with the tail end of hand arm 35,The tail end of hand arm 35 is hinged with the inwall of bundling house,One end of spring 34 is fixing with the top of fixed arm 33 to be connected,The other end of spring 34 is fixing with the middle part of hand arm 35 to be connected;The top of described bundled room 11 is provided with carry-over pinch rolls 12, supports roller 60 and is arranged on the top of carry-over pinch rolls 12, and the silk screen 70 on storage net roller 20 sequentially passes through hold-down roller 31, leads the inside being admitted to bundled room 11 after drawing net roller 40, support roller 60, carry-over pinch rolls 12;Described driving motor 50 passes through transmission band band movable belt pulley 51 and rotates, and belt wheel 51 drives master to draw net roller 40 by power transmission shaft and rotates, and belt wheel 51 supports roller 60 by the drive of transmission band and rotates;The outside of described support roller 60 is provided with draws web plate 61, draws web plate 61 and to support roller 60 tangent and draw the bottom of web plate 61 and support that roller 60 is fixing to be connected;Described net device of cutting includes telescoping hydraulic cylinder 81 and cuts net cutter 82, cuts net cutter 82 and is arranged on support roller 60 opposite, and the telescopic end of telescoping hydraulic cylinder 81 is fixing with the tail end cutting net cutter 82 to be connected.
Can automatically work for ease of described circular baler net chute installation, the side of described bundled room 11 is provided with pressure switch 52, the normally opened contact on pressure switch 52 and driving motor 50 place circuit connected in series.
After straw in bundled room 11 is become bale by bundling, after bale reaches the setting value of pressure switch 52 to the extruding force of pressure switch 52, normally opened contact Guan Bi on pressure switch 52, motor 50 is driven to work, under the drive driving motor 50, the main net roller 40 that draws rotates with support roller 60, tension force by tension-adjusting gear regulation silk screen 70, the overtension avoiding silk screen 70 causes silk screen 70 to be torn, avoid the tension force of silk screen 70 too small cause silk screen 70 there is no enough frictional force drives it advances, silk screen 70 is sent in bundled room 11, under the silk screen 70 frictional force drives between bale and rotating pressure roller, bale is wound around, parcel;Telescoping hydraulic cylinder 81 controls to cut net cutter 82 to cut off silk screen 70, completes to put net operation.Wherein, telescoping hydraulic cylinder 81 is controlled by the hydraulic control system on baler, controls to release the length of silk screen 70 according to the time interval of stretching out of the telescopic end of telescoping hydraulic cylinder 81.
Tension-adjusting gear ensures that silk screen 70 has enough tension force, it is simple to cuts net cutter 82 and is cut off by silk screen 70.When silk screen 70 falls off from support roller 60 when putting net, drawing net, utilizing tension-adjusting gear that the tension force of silk screen 70 is down to zero, the most under gravity, silk screen 70 hangs to supporting on roller 60, is supported roller 60 and captures, reduces and draw net operation fault rate.
The control method of tension-adjusting gear: utilizing hand arm 35 to drive hold-down roller 31 to advance or retreat the tension force of coarse adjustment silk screen 70, spring 34 has buffering, regulation effect, the tension force of automatic fine tuning silk screen 70, it is ensured that the tension force of silk screen 70 is in the range of setting value.
The effect drawing web plate 61 is, on the one hand makes to draw to carry-over pinch rolls 12 silk screen 70 of cut-out, it is to avoid silk screen 70 occurs off-grid;On the other hand, drawing web plate 61 and have the effect of support, support is cut net cutter 82 and is cut off by silk screen 70, it is to avoid cuts net cutter 82 and damages support roller 60.
For ease of controlling the length being wrapped on bale of silk screen 70, the integral multiple that the length that silk screen 70 is wrapped on bale is bundled room 11 girth need to be controlled;The internal diameter of described bundled room 11 is R, and the external diameter of carry-over pinch rolls 12 is equal to the external diameter of rotating pressure roller, and the external diameter of carry-over pinch rolls 12 is r, and R=nr, n are the integer more than 4;The external diameter of described support roller 60 is equal to the external diameter of carry-over pinch rolls 12.The external diameter of carry-over pinch rolls 12 is equal to the external diameter of rotating pressure roller, it is easy to silk screen 70 advance in bundled room 11 under the effect of frictional force, R=nr, n is the integer more than 4, not only ensure that there are enough spaces bundled room 11, but also the length that beneficially control silk screen 70 is wrapped on bale is the integral multiple of bundled room 11 girth, it is simple to the counting device on baler.The external diameter of described support roller 60 ensures to support roller 60 equal to the external diameter of carry-over pinch rolls 12 and carry-over pinch rolls 12 can realize synchronizing, i.e. when cutting net cutter 82 and silk screen 70 being cut off, what net cutter 82 was cut in support is to draw web plate 61, when circulation is put net again, is cut net, make to cut net cutter 82 second time when being cut off by silk screen 70, support that cut net cutter 82 is to remain to draw web plate 61.
For preventing silk screen 70 from falling off during advancing, described master draws the lower section of net roller 40 and is provided with from drawing net roller 41, from drawing net roller 41 and main drawing is provided with the gap passed for silk screen 70 between net roller 40.
For ensureing that the silk screen 70 cut off can be drawn capture by carry-over pinch rolls 12 from supporting roller 60 smoothly, described in draw the back side of web plate 61 and be provided with the first hairbrush layer 62, the first hairbrush layer 62 is fixing with the back side drawing web plate 61 to be connected;Being provided with the second hairbrush layer 121 on the curved surface of described carry-over pinch rolls 12, the second hairbrush layer 121 is fixing with carry-over pinch rolls 12 to be connected.First hairbrush layer 62 improves the frictional force drawn between web plate 61 and silk screen 70, and the silk screen 70 being beneficial to will be switched off is delivered on carry-over pinch rolls 12;Second hairbrush layer 121 improves the frictional force between carry-over pinch rolls 12 and silk screen 70, is not only beneficial to capture silk screen 70, is additionally favorable for that silk screen 70 traction is delivered to bundled room 11 internal simultaneously.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
