DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0020] The utility model provides a technical solution: as Figures 1 to 4As shown in the figure, in this embodiment, a protective structure for a rotary tillage boat includes a rotary tillage boat body 1. An engine 2 is installed inside the rotary tillage boat body 1. A rotating shaft 3 is rotatably installed at the front end of the rotary tillage boat body 1 through mechanical seals. A crushing knife 4 for crushing weeds is fixedly installed at the end of the rotating shaft 3. Transmission rods 5 are symmetrically and rotatably installed on both sides of the front end of the rotary tillage boat body 1. A pushing plate 6 for pushing weeds is fixedly installed at the end of the transmission rod 5.

[0021] As Figures 1 to 4 shown, mounting brackets 7 are symmetrically and fixedly installed inside the front end of the rotary tillage boat body 1. A rotating rod 8 is rotatably installed between the two mounting brackets 7 through bearings. A driving bevel gear 9 is fixedly installed in the middle of the rotating rod 8. A driven bevel gear 10 is fixedly installed at the end of the rotating shaft 3 away from the crushing knife 4. The driven bevel gear 10 is meshed and connected with the driving bevel gear 9.

[0022] When the engine 2 operates, it will drive the rotating rod 8 to rotate, drive the driving bevel gear 9 to rotate. Through the meshing of the driven bevel gear 10 and the driving bevel gear 9, it will drive the rotating shaft 3 to rotate, and then drive the crushing knife 4 to rotate, so as to crush weeds and prevent the weeds from entangling on the impeller of the rotary tillage boat body 1 for protecting the impeller.

[0023] As Figures 1 to 4 shown, discs 11 are symmetrically and fixedly installed at both ends of the rotating rod 8. A guide groove 12 is formed in the middle of the disc 11. The guide groove 12 is arranged in an arc-shaped and communicating manner. A fixing rod 13 is fixedly installed at the end of the transmission rod 5. A spherical ball block 14 is fixedly installed at the end of the fixing rod 13 away from the transmission rod 5. The spherical ball block 14 is located inside the guide groove 12 and is arranged to slide by extrusion with the guide groove 12.

[0024] Through the operation of the engine 2, it will drive the rotating rod 8 to rotate, and then drive the disc 11 to rotate. Since the spherical ball block 14 is located inside the guide groove 12 and slides by extrusion with the guide groove 12, it will drive the transmission rod 5 to rotate reciprocally left and right, drive the pushing plate 6 to swing reciprocally, and can push the weeds at both sides of the rotary tillage boat body 1 in the field to the middle of the rotary tillage boat body 1, improving the cleaning effect of the weeds in the field.

[0025] As Figures 1 to 4 shown, a circular block 15 is fixedly installed in the middle of the transmission rod 5. A circular groove 16 is formed in the rotary tillage boat body 1 corresponding to the circular block 15. The circular groove 16 and the circular block 15 are arranged to rotate in a sealed manner.

[0026] During the rotation of the transmission rod 5, the transmission rod 5 will rotate in a sealed manner inside the circular groove 16, which can prevent water or mud from entering the inside of the rotary tillage boat body 1.

[0027] As Figures 1 to 4As shown, a pulley 17 is fixedly installed at the output shaft position of the engine 2, and a transmission disc 18 is fixedly installed at one end of the rotating rod 8. A transmission belt 19 is installed between the pulley 17 and the transmission disc 18 for transmission.

[0028] When the engine 2 operates to drive the movement of the tiller boat body 1, the rotation of the rotating rod 8 will be driven through the transmission between the pulley 17 and the transmission disc 18 by the transmission belt 19, which can drive the push plate 6 to swing reciprocally and the crushing knife 4 to rotate simultaneously, without the need to use multiple output power control devices for operation.

[0029] As Figures 1 to 4 shown, the push plate 6 is arranged at an obtuse angle.

[0030] The weeds in a large area on both sides of the tiller boat body 1 in the field can be pushed to the middle of the tiller boat body 1.

[0031] The present utility model provides a protective structure for a tiller boat, and the specific working principle is as follows:

[0032] When the device is in use, the operation of the engine 2 will drive the movement of the tiller boat body 1, and at the same time, the rotation of the rotating rod 8 will be driven through the transmission between the pulley 17 and the transmission disc 18 by the transmission belt 19, and then the rotation of the disc 11 will be driven. Since the spherical block 14 is inside the guide groove 12 and slides by extrusion with the guide groove 12, the transmission rod 5 will be driven to rotate reciprocally left and right, and the push plate 6 will be driven to swing reciprocally. The weeds at the positions on both sides of the tiller boat body 1 in the field can be pushed to the middle of the tiller boat body 1. At the same time, the rotation of the rotating rod 8 will drive the rotation of the driving bevel gear 9, and the rotation of the rotating shaft 3 will be driven through the meshing of the driven bevel gear 10 and the driving bevel gear 9, and then the crushing knife 4 will be driven to rotate to crush the weeds.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
