However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present utility model to those skilled in the art.

[0020] Embodiment 1: A lawn laying device, as Figures 1 - 4 shown, includes a chassis 1. Two placement grooves are formed at the top of the chassis 1. The two placement grooves on the chassis 1 are symmetrically arranged. Four universal wheels 2 are fixedly connected to the bottom of the chassis 1. The four universal wheels 2 are evenly spaced. A handrail frame 3 is fixedly connected to the chassis 1. A turf roll 4 is placed between the two placement grooves on the chassis 1. The two placement grooves on the chassis 1 are used to place the turf roll 4. A laying mechanism is provided on the chassis 1. A cutting mechanism is provided on the chassis 1. The staff can evenly lay the turf roll 4 on the soil through the laying mechanism, and can conveniently perform continuous turf laying. The laying mechanism drives the cutting mechanism to cut the turf roll 4 into uniformly sized turf during the turf laying process, improving the turf laying efficiency.

[0021] The laying mechanism includes a motor 5. The motor 5 is fixedly connected to the outer side wall of the chassis 1. A driving roller 6 is rotatably connected to the inner wall of the chassis 1. One end of the driving roller 6 is fixedly connected to the output shaft of the motor 5. The motor 5 is used to drive the driving roller 6. A driven roller 7 is rotatably connected to the inner wall of the chassis 1.

[0022] The laying mechanism further includes a gear one 8. One end of the driving roller 6 is fixedly connected to the gear one 8. The driving roller 6 is used to drive the gear one 8 to rotate. One end of the driven roller 7 is fixedly connected to the gear two 81. Both the gear one 8 and the gear two 81 are located outside the chassis 1. The gear one 8 and the gear two 81 are meshed. The driving roller 6 drives the gear two 81 to rotate through the gear one 8, and then drives the driven roller 7 to rotate.

[0023] The cutting mechanism includes a rotating shaft 9, and the rotating shaft 9 is rotatably connected to the inner wall of the chassis 1. The rotating shaft 9 is located above the driven roller 7. A cam 10 is fixedly connected to the rotating shaft 9, and the rotating shaft 9 is used to drive the cam 10 to rotate. A third gear 11 is fixedly connected to one end of the driven roller 7 close to the motor 5, and a fourth gear 12 is fixedly connected to one end of the rotating shaft 9 close to the motor 5. The fourth gear 12 is used to drive the rotating shaft 9 to rotate. The third gear 11 meshes with the fourth gear 12, and the driven roller 7 drives the fourth gear 12 to rotate through the third gear 11, thereby driving the rotating shaft 9 to rotate.

[0024] The cutting mechanism further includes a sliding frame 13. The sliding frame 13 is slidably connected to the chassis 1. The sliding frame 13 is located between the driven roller 7 and the rotating shaft 9. The top of the sliding frame 13 contacts the cam 10, and the cam 10 is used to push the sliding frame 13 downward. Two vertical springs 14 are connected between the sliding frame 13 and the chassis 1. The two vertical springs 14 are symmetrically arranged. A blade 15 is fixedly connected to the bottom of the sliding frame 13. The sliding frame 13 is used to drive the blade 15 to move up and down, and the blade 15 is used to cut the grass roll.

[0025] Initially, the staff first places the grass roll 4 into the placement groove at the top of the chassis 1, then passes one end of the grass roll 4 around the driving roller 6 and the driven roller 7 so that one end of the grass roll 4 contacts the soil. Then the staff starts the motor 5 and pulls the handrail frame 3 to move horizontally. The horizontal movement of the handrail frame 3 drives the chassis 1 to move horizontally. The output shaft of the motor 5 rotates to drive the driving roller 6 to rotate. The rotation of the driving roller 6 drives the first gear 8 to rotate. The rotation of the first gear 8 drives the second gear 81 to rotate. The rotation of the second gear 81 drives the driven roller 7 to rotate. The driving roller 6 and the driven roller 7 rotate to drive the turf to be evenly laid on the soil. Through the above operations, it is convenient for the staff to continuously lay the turf. When the driven roller 7 rotates, it will drive the third gear 11 to rotate. The rotation of the third gear 11 drives the fourth gear 12 to rotate. The rotation of the fourth gear 12 drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the cam 10 to rotate. The rotation of the cam 10 will squeeze the sliding frame 13 downward, and the vertical spring 14 is compressed. The downward movement of the sliding frame 13 drives the blade 15 to move downward. The blade 15 moves downward to cut the grass roll 4. When the cam 10 continues to rotate and no longer squeezes the sliding frame 13 downward, the vertical spring 14 will rebound and drive the sliding frame 13 to move upward to reset. The upward movement of the sliding frame 13 to reset drives the blade 15 to move upward to reset. The driven roller 7 continues to rotate, and the blade 15 will continuously cut the grass roll 4. Through the above operations, the grass roll 4 is cut into grass pieces of uniform size during the laying process, improving the laying efficiency. After the laying is completed, the staff turns off the motor 5 and stops pulling the handrail frame 3, which is convenient for the next operation.

[0026] Embodiment 2: On the basis of Embodiment 1, as Figures 1 - 4 shown, it further includes a pressing roller 16. The pressing roller 16 is slidably connected to the chassis 1. The pressing roller 16 contacts the grass roll 4. The pressing roller 16 is used to apply pressure to the grass roll. A horizontal spring 17 is provided between the pressing roller 16 and the chassis 1.

[0027] A number of protrusions are provided on both the driving roller 6 and the driven roller 7. The number of protrusions on the driving roller 6 and the driven roller 7 is used to increase the friction between the driving roller 6 and the driven roller 7 and the grass roll.

[0028] When the staff places the grass roll 4 into the placement groove on the chassis 1, first horizontally push the pressing roller 16, and the horizontal spring 17 is compressed. After the grass roll 4 is placed, the staff releases the pressing roller 16, and the horizontal spring 17 will rebound and drive the pressing roller 16 to move backward and reset. The pressing roller 16 will contact and apply pressure to the surface of the grass roll 4 to prevent the grass roll 4 from loosening and facilitate better laying of the turf.

[0029] The number of protrusions on the driving roller 6 and the driven roller 7 can increase the friction between the driving roller 6 and the driven roller 7 and the grass roll 4, making the laying of the grass roll 4 more smooth.
