[0077] like Figure 1 and Figure 12 As shown, in order to better protect the needle device 6 and prevent the needle device 6 from being broken by the compression and cutting device 4, the present invention further provides a needle protection device 20 on the picking baler. The needle protection device 20 includes a first pull rod 201, a threaded rod 202, and a second pull rod 203 connected in sequence. The two ends of the threaded rod 202 are respectively connected to the first pull rod 201 and the second pull rod 20. The free end of the first pull rod 201 is provided with a joint bearing 204, and the free end of the second pull rod 203 is formed with a long slot hole 203a. The joint bearing 204 is fixed to a cam 30 through a rotating shaft. The cam 30 is installed at one end of the output shaft of the driving device 80. One end of the needle device 6 is set in the long slot hole 203a through the needle bearing 40, so that it slides along the long slot hole 203a, and the other end can swing within a fixed angle around the hinge point of the frame 1, forming a crank slide mechanism with the end of the needle bearing 40.

[0078] The utility model is a machine tool used in conjunction with a tractor. When working, the tractor traction plate is connected to the front end of the traction frame 130, and the tractor power output shaft is connected to the transmission shaft 60.

[0079] During operation, the tractor pulls the implement forward, and the power of the tractor power output shaft is transmitted to the flywheel 70 through the transmission shaft 60, and then transmitted to various moving parts through the gear box 3. The height of the picker 160 is adjusted by the picker lifting device 150. When the tractor moves forward, the picker 160 picks up the grass strips laid on the ground, and the right spiral conveyor 200 and the left spiral conveyor 210 convey the grass or crop straw to the feeding inlet of the frame 1. The feeding device 2 conveys the grass or crop straw at the feeding inlet of the frame 1 into the baling chamber 5. The grass in the baling chamber 5 is compressed and cut. The horizontal movable blade 42 of the cutting device 4 and the vertical fixed blade 81 on the frame cut the grass or crop straw and compress it into a single grass piece 220. The vertical movable blade 43 on the compression and cutting device 4 slides on the vertical movable blade track device 9 and cuts the single grass piece 220 into two single grass pieces, i.e., double grass pieces 230, together with the vertical fixed blade device 8. The double grass pieces 230 are separated by the bundling plate 50. Under the reciprocating action of the compression and cutting device 4, the double grass pieces 230 of grass or crop straw are compressed into square bundles. The upper cutting device track 71 and the lower cutting device track 72 ensure the compression by the lower roller 48 and the upper roller 47. The cutting device 4 is positioned vertically, and the side rollers 49 on the side of the upper cutting device track 71 ensure the left and right position of the compression cutting device 4, so that the compression cutting device 4 performs a crank slider motion. The needle protection device 20, the driving device 80, the compression cutting device 4, the rope knotting device 100 and the needle device 6 have a certain motion relationship. If the motion relationship changes, the needle protection device 20 pulls the needle device 6 out of the baling chamber 5 to prevent the needle device 6 from being broken by the compression cutting device 4. When the bale length reaches the length set by the bale length adjustment device 110, the rope is tied. The knotting device 100 and the needle device 6 start working and tie the baling ropes on the two bales. The bale density adjustment device 10 has the function of adaptively adjusting the bale density. As the straw strips are continuously fed, the two tied bales continue to move backward. Finally, the bale placing device 120 first drops one bale smoothly to the ground, and the other bale drops to the ground smoothly a little later, so that two bales are discharged at a time. According to user requirements, the vertical movable knife 43, the vertical movable knife track device 9, the vertical fixed knife device 8 and the bale separating plate 50 on the compression and cutting device 4 can be removed to discharge one large bale at a time.

[0080] Any matters not described in this utility model are applicable to the prior art.

[0081] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
