[0003] In recent years, steel roller type round balers have been widely used in domestic round baling machinery. When this type of round baler performs net winding operation, it needs to stop and wait, and the time consumed accounts for about 30% of the single bale operation time. At the same time, frequent stops will increase the labor intensity of the driver and accelerate the wear of the tractor clutch. Therefore, it is necessary to develop a round baler that can operate continuously to improve operation efficiency and reduce the labor intensity of the driver, so as to meet the requirements of modern agriculture and animal husbandry for efficient treatment of straw and forage.
[0004] With the development of the times, round balers that can operate continuously have indeed emerged on the market. When operating on soft straw such as wheat and rice in an unchopped state and with a high moisture content, the straw and forage in the front bin are likely to be entangled and torn with those in the rear bin, which may damage the forage channel or cause problems with the winding film, and also reduce the service life of the channel components.

[0037] As Figure 1 , Figure 2 shown, the present utility model discloses a weed entanglement prevention mechanism, which includes a lower bin frame 2, a movable forming roller 3, and a cutting assembly 4. The lower bin frame 2 is arranged on the main frame 11 of the round baler, and one end of the lower bin frame 2 is rotatably connected to the main frame 11 of the round baler. The lower bin frame 2 is connected to the main frame 11 of the round baler through a hydraulic cylinder 13. A pin shaft is arranged on the main frame 11 of the round baler, and a pin shaft is also arranged on the lower bin frame 2. The main body of the hydraulic cylinder 13 is hinged to the pin shaft of the main frame 11, and the telescopic end of the hydraulic cylinder 13 is hinged to the pin shaft of the lower bin frame 2. By driving the hydraulic cylinder 13 to expand and contract, the other end of the lower bin frame 2 can be lifted up and down. The double sprocket feeding roller 14 is rotatably connected to the lower bin frame 2, and the double sprocket feeding roller 14 is located at the rotational connection of the main frame 11 and the lower bin frame 2 and is coaxially arranged with the rotational connection. The movable forming roller 3 is rotatably connected to the lower bin frame 2, and the movable forming roller 3 is located near the rear bin frame 12 of the round baler. The cutting assembly 4 is detachably installed on the lower bin frame 2, and the cutting assembly 4 is located on one side of the movable forming roller 3 close to the rear bin frame 12 of the round baler.
[0038] As Figure 1 , Figure 3 shown, the cutting assembly 4 includes a mounting base 41 and a cutter group 44. The mounting base 41 includes a mounting main board 42 and mounting side plates 43. A mounting side plate 43 is welded to each end of the mounting main board 42, and the two mounting side plates 43 are symmetrically arranged. The mounting side plate 43 has holes, and the side plate of the lower bin frame 2 also has holes. Align the holes of the mounting side plate 43 with the holes of the side plate of the lower bin frame 2, and sequentially pass bolts through them for fixation, realizing that the mounting base 41 is detachably mounted on the lower bin frame 2. Such a setting facilitates the replacement and maintenance of the mounting base 41 in the later stage. At this time, the mounting main board 42 is located between the two side plates of the lower bin frame 2. The mounting base 41 is located at a position of the lower bin frame 2 close to the rear bin frame 12.
[0039] Optionally, as Figure 4 , Figure 5 shown, the cutter group 44 includes a plurality of sub-cutters 45, and the plurality of sub-cutters 45 are sequentially arranged along the longitudinal direction of the mounting main board 42. The sub-cutters 45 are made of manganese steel material, enhancing the strength and toughness of the sub-cutters 45. The angle a of the cutting edge of the sub-cutter 45 ranges from 18° to 28°, and such a cutting edge is more conducive to cutting the forage between the front bin and the rear bin. And a wear-resistant coating is provided at the cutting edge by laser cladding, which can avoid the erosion of the grass juice generated when the forage is cut.
[0040] Optionally, as Figure 3 , Figure 6 shown, the mounting main board 42 of the mounting base 41 has a plurality of mounting holes 421, and the plurality of mounting holes 421 are sequentially arranged at intervals along the length direction of the mounting main board 42. The middle part of the sub-cutter 45 has a fixing hole 451. Fit the sub-cutter 45 with the mounting main board 42, align the fixing hole 451 on the sub-cutter 45 with one of the mounting holes 421 on the mounting main board 42, and sequentially pass bolts through them. In this way, the cutter group 44 is detachably mounted on the mounting main board 42 of the mounting base 41. After the installation is completed, the cutting edge of the sub-cutter 45 is arranged upward, which is more conducive to cutting the forage.
[0041] Optionally, as Figure 6 shown, one side of the sub-cutter 45 has a slide rail 46, and the other side of the sub-cutter 45 has a slide groove 47. In the cutter group 44, the plurality of sub-cutters 45 are sequentially arranged along the longitudinal direction of the mounting main board 42. Among two adjacent sub-cutters 45, the slide rail 46 of one sub-cutter 45 is adapted to the slide groove 47 of the other sub-cutter 45. By arranging the slide rail 46 of one sub-cutter 45 in the slide groove 47 of the other sub-cutter 45, the two sub-cutters 45 are clamped, and the plurality of sub-cutters 45 are installed in the whole cutter group 44 in a detachable manner.
[0042] Optionally, as Figure 6 shown, a limiting edge 48 is provided on the mounting base 41. The limiting edge 48 is located on the mounting main board 42, and the limiting edge 48 is located on one side of the mounting main board 42 along its length direction. The cross-section of the limiting edge 48 is L-shaped, and one side of the limiting edge 48 is fixed on the mounting main board 42. The other side of the limiting edge 48 is arranged upward, and a limiting groove 49 is formed between the limiting edge 48 and the mounting main board 42. When the cutter group 44 is installed on the mounting main board 42, the cutting edge of the sub-cutter 45 is arranged upward, and the end of the sub-cutter 45 away from its cutting edge is located in the limiting groove 49 and abuts against the bottom of the limiting groove
[0043] 49 plays a role in limiting the cutter group 44.
[0044] Optionally, as Figure 1 、 Figure 7 、 Figure 8 shown, the anti-grass entanglement mechanism further includes an anti-leakage baffle 5. The anti-leakage baffle 5 is arc-shaped, and both ends of the anti-leakage baffle 5 have bent edges 51. There are holes on the lower end surface of the mounting main board 42, and there are also holes on one bent edge 51 close to the mounting main board 42. The bent edge 51 is attached to the lower end surface of the mounting main board 42, and the holes on the two are aligned. Then, screws are sequentially passed through to realize the detachable connection between the anti-leakage baffle 5 and the mounting main board 42. The installation position of the anti-leakage baffle 5 is located close to the rear bin frame 12 of the round baler. In addition to being able to cut the forage and prevent the forage from being entangled, the anti-grass entanglement mechanism of the present utility model can also block the feed inlet of the rear bin through the anti-leakage baffle 5 to prevent the forage in the rear bin from leaking out.
[0045] The present utility model also discloses a round baler, including the anti-grass entanglement mechanism described in any one of the above.
[0046] Application scenario of an exemplary embodiment:
[0047] As Figures 1 to 8 shown, when the telescopic end of the hydraulic cylinder 13 retracts, the lower bin frame 2 rotates clockwise to open the channel between the front bin and the rear bin, and the forage enters the front bin and flows through the channel into the rear bin. When the rear bin is filled with forage, the telescopic end of the hydraulic cylinder 13 extends, and the lower bin frame 2 rotates counterclockwise to close the channel between the front bin and the rear bin. As the lower bin frame 2 rotates, the cutter group 44 of the cutting assembly 4 cuts the forage. At this time, the anti-leakage baffle 5 on the lower bin frame 2 blocks the feed inlet of the rear bin to prevent the forage in the rear bin from leaking out.
