[0023] The utility model will be described in detail below in combination with the drawings and specific embodiments.

[0024] Figure 1 The figure is an automatic roller changing mechanism of a grass square paving vehicle, mainly comprising: a front frame 1, a long guide rail 2, a grass roller 3, an inner support rotating mechanism 4, a rear frame 5, a special roller collecting box 6, a short guide rail 7, a rotating blocking mechanism 8, a sliding table 9, a first pushing cylinder 10, and an extension blocking mechanism 11.

[0025] Figure 2 As shown, a set of long guide rails 2 is symmetrically installed above the front frame, used for storing the grass roller 3 and making the grass roller 3 automatically discharge. A set of extension blocking mechanisms 9 is symmetrically installed above the front frame, used for limiting the discharge of the grass roller 3.

[0026] Figures 3-4 As shown, a set of inner support rotating mechanisms 4, short guide rails 7, rotating blocking mechanisms 8, sliding tables 9, and first pushing cylinders 10 are symmetrically installed above the rear frame 5, and a special roller collecting box 6 is installed at the rear. The short guide rail 7 is used to receive the grass roller 3 dropped by the long guide rail 2. The grass roller 3 is blocked by the rotating blocking mechanism 8 and stays at the designated position. The inner support rotating mechanism 4 in the contracted state pushes the grass roller 3 into the special roller 301 through the first pushing cylinder 10, the supporting plate 413 is opened, the grass roller 3 is supported, at this time, the inner support rotating mechanism 4 starts to rotate, the grass screen 302 starts to discharge, and when the discharge is completed, the moving base 402 moves by the first pushing cylinder 10, the mechanism is withdrawn from the special roller 301, the rotating blocking mechanism 8 is released, and the special roller 301 slides along the short guide rail 7 and falls into the special roller collecting box 6. Figure 8 Figure 9

[0027] Figures 2-5 ​​As shown, when the grass roller 3 reaches the designated position, the first push cylinder 10 pushes the moving base 401 to move the inner support rotation mechanism 4, causing the support plate 413 to partially insert into the special roller 301. At this time, the second push cylinder 403 (to avoid the pipeline from getting tangled when the second push cylinder 403 rotates, the second push cylinder 403 is mounted on the rotor of the air slip ring 402 via a connecting plate) retracts, driving the movable rod 410, so that the connecting rod 409 drives the support plate 408 to support the inside of the special roller. At this time, the motor 412 drives the worm gear 411 to drive the worm wheel 404 to rotate. The worm wheel 404 is fixed to the capping shaft 405 by bolts. The capping shaft 405 rotates together with the worm wheel 404. The capping shaft 405 is connected to the transmission cover 406 by bolts. The transmission cover 406 and the capping shaft 405 rotate together. The transmission cover 406 is connected to the guide plate 407 by a connecting column and rotates together. The grass roller 3 rotates together to complete the feeding. After the material is fed, the second push cylinder 403 pushes the movable rod 410 to retract, causing the inner support rotation mechanism to enter the retracted state. Figure 8 The rotating blocking mechanism 8 lowers the blocking plate 801, the first push cylinder 10 retracts, driving the movable base 401 to move, causing the inner support rotating mechanism 4 to leave the special roller 301. The special roller 301 falls along the short guide rail 7 into the special roller collection box 6. At the same time, the electrically controlled rotary table 802 raises the blocking plate 801, and the telescopic cylinder 1102 drives the blocking rod 1101 to retract, causing the next grass roller 3 to reach the short guide rail 7 along the long guide rail 2. The grass roller 3 is blocked by the blocking plate 801 and reaches the designated position. The telescopic cylinder 1102 pushes the blocking rod 1101 to block the next grass roller 3. The above steps complete one operation.

[0028] Note: The cylinders, motors and other drive components mentioned in this embodiment can all be conventional models in the field. Their specific control circuits and programs are existing technologies and will not be described in detail here.
