Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Embodiment 1
As shown in Figure 1, the baler includes rack 1, the front end of rack 1 the embodiment of the invention provides a kind of baler
Equipped with pick-up unit 2, the downstream of pick-up unit 2 is equipped with extrusion chamber 16, is equipped between extrusion chamber 16 and pick-up unit 2 stalk is defeated
It send to the conveying device of extrusion chamber 16, pick-up unit 2 and conveying device are well known to those skilled in the art, no longer superfluous herein
It states, is equipped with net roll positioned at the top of conveying device in rack 1 and room 4 is installed, the top that net roll installs room 4 is equipped with several exhibition net rolls
8, the lower section of exhibition net roll 8, which is equipped with, cuts solarium 3, the tool apron 14 for being equipped in solarium 3 and being driven by power device is cut, if tool apron 14 is equipped with
Dry weft cutter 10, weft cutter 10 is equipped with several blades being laterally extended, and cuts and is rotatably equipped with plastic cutter roller in solarium 3
11, be equipped on plastic cutter roller 11 it is several hooking knife 12, it is every line cutter 10 be located at corresponding two adjacent hooking knives 12 it
Between, every includes being arranged in parallel and adjacent the first plastic cutter 1201 and the second plastic cutter 1202 hooking knife 12, the first plastic cutter 1201
Warp cutting gap, the warp of the corresponding silk screen of every warp cutting gap, tool apron 14 are formed between the second plastic cutter 1202
Be equipped with it is several warp cutter 13, it is every that warp cutter 13 is corresponded to corresponding warp cutting gap, the knife of warp cutter 13
Sword is located at below the blade of corresponding line cutter 10, and silk screen is equipped between plastic cutter roller 11 and tool apron 14 and is entered between the silk screen of extrusion chamber 16
Gap.
14 one end of tool apron is articulated in rack 1, and other end connecting power device, the power device includes first hydraulic cylinder
15。
The blade of hooking knife 12 around plastic cutter roller 11 the centre of gyration annular array setting there are four, be located at same axis direction
On the blade of hooking knife 12 stagger successively, the angle between the blade of two adjacent hooking knives 12 is 1 degree.So that silk screen quilt
It not instead of on same breadth while being cut off when cutting, is gradually cut off from one end toward the other end, avoids the entire width of silk screen
Active force unevenly causes silk screen cutting to be not thorough on face.
In use, silk screen is drawn by net roll, it is unfolded through exhibition net roll 8, then introduce extrusion chamber 16 through silk screen gap, when stalk is rolled up
At round bale reach setting value after, net roll starts to send net, and the silk screen of submitting enters extrusion chamber 16 with conveying device and starts in circle
Outer surface package is tied, when reaching after sending netting index value of setting, first hydraulic cylinder 15 drives tool apron 14 to shift to plastic cutter roller 11, while
So that silk screen shifts to plastic cutter roller 11, hooking knife 12 catches on silk screen, and the weft of silk screen is pressed in weft and cut by two adjacent hooking knives 12
On the blade of knife 10, weft is cut off, and warp is then between the first plastic cutter 1201 and the second plastic cutter 1202, by warp cutter 13
It cuts off.
