The working principle is as follows:
(1) shoveling stage
The second connecting rod 17 is initially positioned in a vertical direction, and is an initial position of the mechanism, the shovel does not have the acting force of shoveled objects (such as silt, broken stones and the like) to keep horizontal, the rotation limiting rope 25 also keeps loose, the first connecting rod 6 also rotates along with the rotation of the motor-driven input sleeve rod 4 and the output sleeve rod, and the shovel cannot be lifted due to the action of the shovel spring 16, but walks for a distance along a straight line in a track to shovel the shoveled objects on the ground.
(2) Stage of lifting
When the shovel moves along a straight line for a certain distance, the pulling force of the shovel spring can be increased along with the increase of the distance, when the pulling force is larger than the weight of the shovel and the object, the shovel can be separated from the ground and lifted by the shovel spring, and the object rotates along with the second connecting rod 17 at the moment.
(3) Parabolic phase
When the second connecting rod 17 moves to a specified position, the second connecting rod 17 stops moving immediately, objects in the shovel are thrown out due to inertia, meanwhile, along with the increase of the moving distance of the second connecting rod 17, the rotation limiting rope 25 is also tensioned, the shovel is driven to rotate relative to the shovel connecting rod 26, the objects are thrown out towards the lateral front, at the moment, the input loop bar 4 and the output loop bar 5 continue to rotate, the connecting rod spring 3 is compressed, and the length between the input loop bar 4 and the output loop bar 5 is shortened.
(4) Return phase
When the parabolic phase is over, the distance between the input and output rods 4 and 5 is restored to the original length, and since the first link 6 has passed the limit position for a while, the speed of the first link 6 will gradually increase from zero; meanwhile, due to the arrangement of the shovel limiting ring assemblies, the second connecting rod 17 gradually returns to the initial position along the track groove 16, and the moving track of the shovel is ensured due to the arrangement of the two limiting ring assemblies in the whole process.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
