Abstract

A mower system comprising a powered mower, a connecting device connected to the powered mower and an attachment connected to the powered mower through the connecting device for conducting specified function during the operation of the mower system. The connecting device includes a mounting assembly mounted to the powered mower and a base rotatably mounted to the mounting assembly for driving the attachment being rotated together with the base in a horizontal plane relative to the powered mower. The utilization rate of the powered mower is effectively improved because other working functions can be conducted by the attachment which is connected to the powered mower through the connecting device.

First claim

What is claimed is:

1. A connecting device, comprising:
a mounting assembly, one end of the mounting assembly being coupled to a vehicle equipment;
a base, the base connected to the other end of the mounting assembly, the base being configured to be connected to an operating device;
an adjustment assembly coupled to the mounting assembly and the base;
wherein the base is lifted upwardly with the mounting assembly as a fulcrum when the adjustment assembly is actuated by an external force,
wherein the adjustment assembly comprises:
an adjusting rod, the adjusting rod being mounted on the mounting assembly and capable of rotating with the mounting assembly as a pivot point;
a connecting rod, one end of the connecting rod being connected to the adjusting rod and the other end of the connecting rod being connected to the base;
when the adjusting rod is actuated by the external force, the adjusting rod drives the connecting rod so as to lift the base upwardly.

2. The connecting device according to claim 1 , wherein an input end of the adjusting rod is configured with a pressing portion, the pressing portion being manually actuated.

3. The connecting device according to claim 1 , wherein an input end of the adjusting rod is driven by a power unit.

4. The connecting device according to claim 1 , wherein the base is pivotally mounted to the mounting assembly by means of a pivot axis so as to allow the base to be rotatable about the pivot axis in a plane of operation.

5. The connecting device according to claim 4 , wherein the base rotates about the pivot axis at an equally spaced angle.

6. The connecting device according to claim 4 , wherein an angle of rotation of the base about the pivot axis is a non-equally spaced angle.

7. The connecting device according to claim 4 , wherein further comprises a control assembly connected to the base by controlling the control assembly to rotate the base to a desired position.

8. The connecting device according to claim 4 , wherein further comprises a connecting frame, one end of the connecting frame being pivotally connected to the mounting assembly and the other end of the connecting frame being connected to the base.

9. The connecting device according to claim 1 , wherein the mounting assembly is configured with a mount for attachment to the vehicle equipment.

10. The connecting device according to claim 9 , wherein the mount is removably connected to the vehicle equipment.

11. The connecting device according to claim 1 , wherein the vehicle equipment is one of a lawn mower, a bulldozer, a scraper, a tractor, a truck, a car.

12. The connecting device according to claim 1 , wherein the operating device is one of a snow shovel, a snow sweeping device, a dozer blade, a transport blade, a cultivating device, a plowing device.

13. A vehicle system, comprising:
a vehicle equipment;
a connecting device, mounted to the vehicle equipment, the connecting device comprises:
a mounting assembly, one end of the mounting assembly being connected to the vehicle equipment;
a base, the base connected to the other end of the mounting assembly, the base being configured to be connected to an operating device;
an adjustment assembly coupled to the mounting assembly and the base;
wherein the base is lifted upwardly with the mounting assembly as a fulcrum when the adjustment assembly is actuated by an external force,
wherein the adjustment assembly comprises:
an adjusting rod, the adjusting rod being mounted on the mounting assembly and capable of rotating with the mounting assembly as a pivot point;
a connecting rod, one end of the connecting rod being connected to the adjusting rod and the other end of the connecting rod being connected to the base;
when the adjusting rod is actuated by the external force, the adjusting rod drives the connecting rod so as to lift the base upwardly.

14. The vehicle system according to claim 13 , wherein an input end of the adjusting rod is actuated by an external force.

15. The vehicle system according to claim 13 , wherein the base is pivotally mounted to the mounting assembly by a pivot axis so as to allow the base to be rotatable about the pivot axis in a plane of operation.

16. The vehicle system according to claim 15 , wherein further comprises a control assembly connected to the base by controlling the control assembly to rotate the base to a desired position.

17. The vehicle system according to claim 13 , wherein the vehicle equipment is one of a lawn mower, a bulldozer, a scraper, a tractor, a truck, a car.

18. The vehicle system according to claim 13 ,
wherein the connecting device is configured to cause the operating device to rotate in a work plane and/or to be lifted in a vertical direction.
