Description

A trailed trimming system for a garden tractor

technical field

Background technique

At present, the pruning of landscaping belts is generally carried out by hand-held pruning machines. Due to the weight of the pruning machines, it is difficult for workers to prune green plants in high places, which may lead to physical fatigue and certain safety hazards.

For square hedges with a large amount of pruning tasks, automated machines are also used to prune them. However, when one-way pruning of square hedges is performed by automated machines, on the path cut by the blade, the hedge branches have a certain toughness. Part of the branches located at the lower part of the branches and leaves are pressed by another part of the branches. After pruning the branches that protrude outward from the hedge, the suppressed part is released from the restriction, so as to protrude to the outside, so that the upper part of the hedge cannot be completely cut, and there is cutting. The problem of omission is that the height of the hedge that is not trimmed by the machine is higher than the height of the hedge after trimming, which affects the overall appearance; and when the machine collects the branches and leaves of the trimmed hedge, the branches and leaves are still missing to the ground, and the collection effect is Poor, requires workers to clean it up, increasing the workload of workers.

As the tractor controls the robotic arm to advance along the hedge path, the first motor 5 controls the first blade 6 to prune the upper part of the green plant. At this time, there is still an inability to completely prune the upper branches and leaves of the hedge, resulting in a hedge that has not been cut by the first blade 6. The branches and leaves form a contrast with the pruned hedgerows and leaves, which affects the overall aesthetics of the hedge, and requires subsequent staff or operating machines to prune it again, which is not conducive to improving work efficiency; the first motor 5 drives the first blade 6 to rotate. At the same time, the first gear 7 rotates synchronously in the groove 3, the first gear 7 drives the second gear 8 to rotate, and the second gear 8 is located in the groove 3 on the side close to the collecting pipe 14, so that the second gear 8 rotates 8 After the rotation, the second blade 10 is controlled to rotate rapidly by the connecting rod 9, so that the hedge branches and leaves that are not cut by the first blade 6 are trimmed, so as to avoid secondary work, improve the work efficiency of the application, and have certain practical performance;

The hedge branches and leaves cut by the first blade 6 and the second blade 10 have a certain kinetic energy after they are separated from the hedge, so that the green plants move towards the inner wall of the shutter 2. When the hedge branches and leaves move to the space above the collecting plate 12, in the cylinder 11 Under the action, the gas generated by the cylinder 11 is ejected through the nozzle 13, so that the green plants that move to the space above the collecting plate 12 are blown upward, and as the shutter 2 moves forward, the blown green plants gradually fall to the shutter 2. Above the collecting plate 12 in the width direction, the collecting pipe 14 is communicated through an external negative pressure device, and the negative pressure device is a negative pressure suction device, so that a negative pressure is generated in the collecting pipe 14 to realize the collection falling to the width direction of the shutter 2 The hedge branches and leaves above the board 12 are attracted, and the hedge branches and leaves enter the collection box (not shown in the drawings) provided on the tractor through the collection pipe 14, so as to realize the collection of the hedge branches and leaves trimmed by the first blade 6 and the second blade 10 , reducing the pruned hedge branches and leaves from falling to the ground, so as to avoid the secondary collection by the staff, which has certain practicality.

As an embodiment of the present invention, the collecting plate 12 disposed along the width direction of the cover plate 1 is arc-shaped to form a collecting bin 15 , and the collecting bin 15 is located in the collecting bin 15 disposed along the length direction of the cover plate 1 . the lower part of the collecting plate 12;

During operation, the lower part of the collecting plate 12 arranged along the width direction of the cover plate 1 presents an arc shape, and the arc-shaped part forms a collecting bin 15 on the side facing the cover plate 1, and the collecting bin 15 is located at the lower part of the collecting plate 12 arranged along the length direction of the cover plate 1;

The first blade 6 and the second blade 10 are located on the upper part of the collection bin 15, so that after the first blade 6 and the second blade 10 cut the hedge branches and leaves, some of the cut hedge branches and leaves fall to the upper part of the cut hedge, and follow the tractor along the hedge. When the hedge path moves forward, the upper end of the collection bin 15 squeezes the upper part of the cut completed hedge, so that the branches and leaves falling on the upper part of the hedge enter the collection bin 15, so as to avoid the branches and leaves falling on the upper part of the hedge from affecting the overall aesthetics of the hedge after pruning is completed, and After the collection bin 15 squeezes the upper part of the branches and leaves of the hedge, the gap between the branches and leaves of the hedge changes, and the hedge branches and leaves that have been trimmed and have not entered the collection bin 15 enter and fall to the lower part through the above-mentioned gap, so as to avoid the pruned branches and leaves. The hedge branches and leaves are dried and withered on the pruned hedge branches and leaves, which affects the overall aesthetics. At the same time, the hedge branches and leaves on the upper part of the collection plate 12 in the width direction of the cover plate 1 continuously enter the collection bin 15. At this time, the bottom of the collection bin 15 can be set in an arc shape to Increase the storage capacity of the collection bin 15 to avoid the problem that the first blade 6 and the second blade 10 cut faster and the hedge branches and leaves drawn away by the collection tube 14 are slower, so that the collection bin 15 is fully loaded and the branches and leaves leak out of the outside. In addition, the bottom of the collection bin 15 is arc-shaped, which can effectively ensure that the bottom of the collection bin 15 will not fold or deform the hedge branches during the advancing process of the cover plate 1, thereby effectively improving the practical performance of the present application.
