However, the later trimming of the hedgerow has the gradual disadvantages and inconveniences:

firstly, the hedgerow is in an arch shape, no special auxiliary positioning equipment is needed during trimming, the hedgerow trimmer is held by a worker to trim, the mode is completely controlled by the experience of the worker, the standard degree of trimming is difficult to guarantee, the height and the arch degree after the hedgerow is trimmed are often not uniform, the visual effect is poor, and the original intention of improving the urban aesthetic feeling is difficult to realize.

Moreover, the trimming effect is completely dependent on the operational skill of workers, and the construction cost is difficult to control under the condition of high labor cost.

Secondly, in order to carry out effective auxiliary positioning to facilitate manual trimming of workers, at present, an arch shape is rolled on a hedge by utilizing wood bars and ropes, namely a plurality of wood bars are inserted into two ends of the hedge to be trimmed, the height between the wood bars is determined according to the shape of the hedge, the wood bars with the corresponding heights at the two ends of the hedge are connected by a plurality of ropes, so that the ropes can form a plurality of straight lines on the surface of the hedge, and the workers can trim by holding the hedge trimmer by hands according to the ropes. However, this method cannot avoid natural sagging and deformation of the cord, and although accuracy is improved, it is difficult to control.

Moreover, the hedgerow length of both sides of the road can reach hundreds of meters or even longer, the mode of adopting the manual rolling stick and cotton rope to assist is very slow, and the continuous repeated disassembly and assembly are needed, thus seriously influencing the working efficiency.

Therefore, it is necessary to design an auxiliary positioning device with high speed, simplicity and efficiency to improve the trimming effect and efficiency and reduce the construction cost.

Traditional arch location relies on the cotton rope, and as the distance that the cotton rope was dragged increases, its natural flagging amplitude just is big more, has directly influenced the degree of accuracy of pruning. After the laser spot lamp is adopted, the laser ray is straight and has no deviation, and a worker can easily observe the relative position by naked eyes, so that the quick and accurate trimming operation is realized. Moreover, the whole shape is stable and not easy to deform, and the whole shape can not deform after being repeatedly used, so that the inconvenience of repeated disassembly and assembly is avoided.

Taking the pruning of the hedgerow on the two sides of the road for 200 meters as an example, the manual flat shearing mode and the manual mechanical pruning mode are adopted to compare, and the effect is as follows:

the four times of manual flat shearing have a Dada scale: 79%, 76%, 72%;

the four times of the manual mechanical trimming are on the scale of: 81%, 77%, 79%, 84%.

After the utility model is used, the time required for pruning the nursery stock of 1.5m multiplied by 30m is between 10min and 15min, and the efficiency is improved by about 25 percent. At 150m²Four points are randomly selected from the nursery stocks in the area, the uniform height error after pruning is +/-2 cm, and the regular and ordered pruning qualification rate reaches more than 90%. And the utility model discloses a mechanical cost is about 400 yuan, and life cycle is about 3 years, and the cost of manufacture is very cheap, and self-processing can.

Taking the improvement of a certain foundation facility in the city as an example, the whole length of the project is two kilometers, the side branch is greened to about 7000 square meters, manual pruning is carried out by manpower by experience, and compared with pruning after auxiliary positioning by using the product, the differences are as follows:

manually pruning according to experience: the labor cost per square is 0.65 yuan, the cost for trimming once is 4550 yuan, and the cost for trimming twice per month is 9100 yuan;

pruning after utilizing this product assistance-localization real-time: the labor cost per square is 0.4 yuan, the one-time trimming cost is 2800 yuan, the two-time trimming cost per month is 5600 yuan, and the product cost amortizes the monthly cost to be 125 yuan;

after comparing with the two, utilize this product assistance-localization real-time back to prune and can save cost 3375 yuan, the degree of difficulty of manual operation reduces by a wide margin importantly, and ordinary workman can all prune the operation, and the effect is levelly and smoothly unified pleasing to the eye degree height.

The utility model discloses still have following advantage:

1. the manufactured arc aluminum sheet has light weight and is smooth and has no bending.

2. The laser spot lamp can be used in all weather, and is easy to be observed by naked eyes.

3. The bolt is connected and fixed, is stable and deformation-free, and is suitable for hard paved ground, road edge stones and lands.

4. After shaping, the continuous operation can be realized without repeated disassembly and assembly; the deformation operation of different shapes is also simple, convenient and quick.

The utility model provides a laser spot lamp and universal regulation support are all from the purchase of the fast electronic factory of Wenzhou Hua, and the irradiation distance of laser spot lamp can reach 50 meters, and the one end and the mutual fastening connection of unit structure spare of universal regulation support, the other end are connected with the laser spot lamp, and the laser spot lamp can carry out the transform of arbitrary angle under the effect of universal regulation support, until keep laser ray's levelness can.

In the construction process, different green plants are planted at intervals of several meters in the hedgerow belt for decoration, the actual length of each arch hedgerow is within about 10 meters, and the auxiliary positioning device is only required to be placed at the end head for leveling. Meanwhile, in order to improve safety, a baffle plate is required to shield the laser ray in the irradiation direction of the laser spot lamp so as to prevent the laser ray from irradiating the eyes of the people on the road.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
