Problems solved by technology
Due to the complex spatial positions of the five installation shaft holes on the frame of the D-type knotter, during the whole knotting process, the relative movement positions of the clamping wheel assembly, the knotting mouth assembly, and the rope release lever assembly are strictly required. Changes in the working environment will reduce the reliability and stability of knot formation, and the "α" knot is easy to loose during transportation, causing the bales to scatter

Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] Such as figure 1 , figure 2 Shown, the present invention comprises a frame 1, connects a knotting mouth 2, a clamping wheel 3, a slider crank linkage mechanism 4, a knot winding mechanism 5, a cutter crank connection on the frame 1. Rod mechanism 6, a set of rope device mechanisms 7, knots 8 connected in series and binding ropes 9 arranged outside the frame 1.
[0027] The knotting nozzle 2 of the present invention is L-shaped as a whole, the vertical section of the knotting nozzle 2 is fixedly connected with a rotating shaft 21, and the rotating shaft 21 is rotatably connected on the frame 1, and the knotting nozzle 2 can be driven by an external force to rotate. The horizontal section of the knotting mouth 2 is tapered conical, and the entrance 22 at the end of the knotting mouth 2 is in a gradually expanding conical shape, and a bundle o...

The invention relates to a theta knot tying device and method of straw. The theta knot tying device is characterized by comprising a rack, a knot tying nozzle, a line clamping wheel, a slider crank-link mechanism, a knot clamp winding mechanism, a cutter crank-link mechanism, a cable apparatus mechanism, knot clamps connected in a string and a bundling rope arranged outside the rack. The knot tying nozzle is connected to the rack in a rotating mode, and the inlet of the knot tying nozzle is provided with a bundling rope groove and a knot clamp groove. The line clamping wheel is connected to the rack in a rotating mode, and a rope pressing apparatus corresponding to the line clamping wheel is arranged. The slider crank-link mechanism comprises a crank connected to the rack in a rotating mode, and the crank is connected with a slider through a link. The knot clamp winding mechanism comprises a rotating winding shaft, and the string of knot clamps are wound around the winding shaft. A support is connected to the front end of the slider, and a conveying wheel is connected to the support. The cutter crank-link mechanism comprises a cutter crank connected to the support, and the cutter crank is connected with a cutter bar in a rotating mode through a cutter link. Because the planar link mechanisms are adopted for controlling the components to move, the theta knot tying device is simple in structure and stable in working, and guarantees that knots are easier to tie and not prone to loosening.
Description
technical field [0001] The invention relates to a straw knotting device and method, in particular to a straw "θ" knotting device and method. Background technique [0002] In straw collection and baling operations, knotters are widely used to tie the ropes wrapped in straw bales. The most used in existing knotters is the D-type knotter (such as Figure 8 As shown), it includes components such as a frame 100, a drive toothed plate 101, a wire clamping wheel assembly 102, a knotting nozzle assembly 103 and a rope removal lever assembly 104. When the D-type knotter is knotting the rope, the rope is sent to the groove of the clamping wheel through the knotting nozzle after wrapping the bale, and then drives the toothed plate to rotate for one circle. At this time, the driving During the rotation of the chainring, the inner teeth of the driving chainring drive the clamping wheel assembly to rotate and clamp the rope end through the secondary transmission of the worm gear, and the...
