Description

Technical Field

[0001] The utility model belongs to the technical field of tree maintenance, and in particular relates to a tree whitewashing positioning device. Background Art

[0002] Whitewashing of trees can effectively prevent frost damage to garden trees in winter, because white is reflective and absorbs less heat. Trees will not be significantly affected by the drastic temperature changes between day and night. It can prevent and reduce sunburn and frost damage, prevent the invasion of pathogens, and also eliminate overwintering pests living on garden trees.

[0003] Before whitewashing trees, in order to ensure the uniformity and aesthetics of the whitewashing positions, the whitewashing positions will be marked. However, the traditional tree whitewashing positioning method is rather cumbersome. It is necessary to first use a ruler to locate the upper and lower heights one by one, and then stick tape or spray red paint on the designated positions for positioning. This repetitive work is large, time-consuming and labor-intensive, and greatly reduces the efficiency of tree maintenance.

[0004] Therefore, a tree whitewashing positioning device was proposed to improve the traditional whitewashing positioning method in order to reduce workload, optimize work procedures and improve work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1-Figure 5 The tree whitewash positioning device shown comprises a positioning rod 1, an outer wall of the positioning rod 1 is slidably connected to an adjustment frame 2, a side wall of the adjustment frame 2 is fixedly connected to a first arc plate 3, an end of one side of the first arc plate 3 is hingedly connected to a second arc plate 4, and the first arc plate 3 and the second arc plate 4 are connected to form a complete circle, an end of the other side of the first arc plate 3 is fixedly connected to an iron frame 5, an end of the second arc plate 4 close to the iron frame 5 is fixedly connected to a magnet 6, and the magnet 6 is adsorbed on the inner side of the iron frame 5, and the position of the first arc plate 3 and the second arc plate 4 is fixed by the attraction between the magnet 6 and the iron frame 5;

[0023] The first arc plate 3 and the second arc plate 4 are both provided with T-shaped grooves 7 inside and through the top ends thereof, a T-shaped block 8 is slidably connected in the T-shaped groove 7, a limiting cylinder 9 is fixedly connected to the side wall of the T-shaped block 8, a sliding frame 10 is slidably connected to the inner side of the limiting cylinder 9, a brush 11 is fixedly connected to the side wall of the sliding frame 10, a paint spraying mechanism for spraying paint onto the brush 11 is provided on the positioning rod 1, a plurality of first springs 12 are fixedly connected between the inner side of the limiting cylinder 9 and the sliding frame 10, and the sliding frame 10 and the brush 11 are pushed outward by the elastic force of the first springs 12, so that the brush 11 is close to the outer wall of the trunk to ensure the painting quality;

[0024] When brushing the positioning paint on the tree trunk, first open the second curved plate 4, then insert the positioning rod 1 next to the trunk through the pointed end 25, and at the same time place the first curved plate 3 next to the trunk, then close the second curved plate 4 to surround the trunk, and at the same time clamp the magnet 6 in the iron frame 5 to fix the positions of the first curved plate 3 and the second curved plate 4, and then start the paint spraying mechanism to spray the paint on the brush 11, and then push the T-block 8 to drive the limiting cylinder 9, the sliding frame 10 and the brush 11 to slide inside the T-slot 7, so as to achieve the comprehensive brushing of the trunk positioning paint to determine the whitening area, which is conducive to the subsequent large-scale whitening work. At the same time, when the trunk size is large, the brush 11 and the sliding frame 10 will be squeezed outward, so that the sliding frame 10 slides in the limiting cylinder 9 and compresses the first spring 12, so that it can be convenient for trees with various tree diameters to be used. Finally, after the painting is completed, the brush 11 is reset and the positioning device can be taken out by reverse operation.

[0025] In order to adjust the brushing position of the brush 11, a bolt 13 is threadedly connected through the front side of the adjustment frame 2, and the side wall of the bolt 13 is squeezed against the outer wall of the positioning rod 1. The squeezing of the outer wall of the positioning rod 1 is released by unscrewing the bolt 13, and the adjustment frame 2 can be slid to adjust the position of the brush 11. After the adjustment is completed, the bolt 13 is tightened in the reverse direction to squeeze and fix the outer wall of the positioning rod 1.

[0026] In order to further improve the accuracy of device positioning, a height scale groove 14 is provided on the front side of the positioning rod 1. The height scale groove 14 enables the height adjustment of the adjustment frame 2 to be more accurate.

[0027] In order to avoid the need to repeatedly use the brush 11 to pick up the paint in the paint bucket, the paint spraying mechanism includes a pump body 15 and a paint spraying head 16. A pair of paint spraying heads 16 are provided. The top of the positioning rod 1 is fixedly connected to a paint storage box 17. The pump body 15 is fixedly connected to the side wall of the paint storage box 17 and the liquid inlet end is connected to the inside thereof. The bottoms of the first curved plate 3 and the second curved plate 4 are both fixedly connected to a C-shaped curved tube 18. The arrangement of the curved tube 18 can guide the movement of the lower corrugated tube 19 and avoid winding around the tree trunk.

[0028] A lower bellows 19 is fixedly connected to the inner side of the arc tube 18 below the first arc plate 3, and an upper bellows 20 is fixedly connected between the side wall of the lower bellows 19 and the liquid outlet end of the pump body 15. Through the setting of the upper bellows 20, it can be stretched when the adjustment frame 2 is adjusted in height to avoid hindering the adjustment of the positioning paint brushing position. The paint spray head 16 is fixedly connected to the side wall of the brush 11, and a connecting tube 21 is provided below the brush 11, and the top of the connecting tube 21 passes through the inside of the brush 11 and is fixedly connected to the paint spray head 16. A connecting frame 24 is fixedly connected between the limiting cylinder 9 and the lower bellows 19, and a hose 22 is fixedly connected between the connecting tube 21 and the lower bellows 19. Through the setting of the hose 22, it is avoided to hinder the extension and retraction of the sliding frame 10 on the limiting cylinder 9. A second spring 23 is fixedly connected between the inner side of the arc tube 18 and the lower bellows 19;

[0029] When painting the tree trunk with positioning paint, first pour the red paint into the paint storage box 17. When the T-block 8 is pulled to drive the brush 11 to move and paint the tree trunk, the pump body 15 is started to extract the paint, which is then sprayed out from the paint spray head 16 through the upper bellows 20, the lower bellows 19, the hose 22 and the connecting pipe 21, and then the paint is sprayed onto the brush 11. With the rotation of the brush 11 around the tree trunk, the tree trunk is fully painted with positioning paint. At the same time, the lower bellows 19 will be stretched in the arc tube 18, and the second spring 23 will be stretched at the same time. After the painting is completed, the tension of the second spring 23 will pull the brush 11 to return to its original position, which is more labor-saving.

[0030] In order to improve the stability of the positioning device during use, a plurality of spikes 25 are fixedly connected to the bottom of the positioning rod 1. Through the arrangement of the spikes 25, when in use, the spikes 25 can be first inserted into the ground next to the tree, thereby effectively fixing the bottom of the positioning rod 1.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
