Description

Technical Field

[0001] The utility model belongs to the technical field of garden auxiliary tools, and in particular relates to a tool for pruning trees in a forest seed garden. Background Art

[0002] Seed gardens are artificial forests composed of selected excellent clones or families. Isolation measures and intensive management measures are taken to eliminate or reduce pollution from external pollen, ensure high and stable yields, and facilitate seed collection. Pruning is the removal of dead, damaged by pests and diseases, or overly dense branches and leaves. Since trees are generally tall, workers often use tools such as straight ladders or stepladders to climb up when pruning. Since straight ladders need to be placed against tree trunks, the bottom of stepladders occupy a large area, which is inconvenient to use when pruning trees. The pedals of the ladders are straight boards with a small stepping area, which is not conducive to keeping people stable when working. Utility Model Content

[0025] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0026] like Figure 1As shown, a tree seed garden pruning tool comprises a triangular ladder and a support tube 1. The triangular ladder comprises two ladder rods 2, a plurality of pedals 3 and a first side plate 4. The ladder rods 2 are straight rods (curved rods may also be selected). The two ladder rods 2 are symmetrically arranged. The plurality of pedals 3 are connected between the two ladder rods 2. The plurality of pedals 3 are arranged at equal distances along the direction of the ladder rods 2. The length of the plurality of pedals 3 gradually shortens from bottom to top, and the triangular ladder as a whole is wide at the bottom and narrow at the top. The two first side plates 4 are respectively connected to the outside of the two ladder rods 2. A rotating shaft 5 runs through the two first side plates 4. The upper end of the support tube 1 is welded to the rotating shaft 5. The support tube 1 is hinged to the two first side plates 4 through the rotating shaft 5, so that the support tube 1 is hinged to the triangular ladder. The support tube 1 can be unfolded or folded relative to the triangular ladder. When in use, the support tube 1 is unfolded to a certain angle. The support tube 1 and the two ladder rods 2 of the triangular ladder form three support feet. The connection line between the lower ends of the three support feet is a triangle, which has high stability. When stored, the support tube 1 is folded. In this embodiment, the two ladder bars 2 and the plurality of pedals 3 are made of aluminum alloy for easy transportation. The first side plate 4 is made of steel plate, and the rotating shaft 5 is made of steel column, which is wear-resistant and has a strong load-bearing capacity.

[0027] The pedal 3 includes an arc-shaped plate 31 and two second side plates 32. The arc-shaped plate 31 has an arc-shaped cross-section. The two second side plates 32 are respectively connected to the two ends of the arc-shaped plate 31. The second side plates 32 are connected to the side surfaces of the ladder rod 2 on the corresponding side. In this embodiment, three rivets are used to rivet the second side plates 32 and the ladder rod 2 on the side, so that the arc-shaped plate 31 is connected between the two ladder rods 2. The radius of the circle where the arc-shaped plate 31 is located is R, and the width of the ladder rod 2 is D, R≥D, so that the arc-shaped plate 31 can maintain a small curvature, which is convenient for people to stand on the arc-shaped plate 31. The line between the midpoint of the arc segment where the arc-shaped plate 31 is located and the center of the circle where the arc-shaped plate 31 is located is the first connecting line. The angle between the first connecting line and the horizontal line is A, 60°≤A≤90°, and the arc-shaped plate 31 will not tilt inward or outward excessively, ensuring that the inclination angle of the arc-shaped plate 31 is within a suitable range, which is convenient for staff to stand on the arc-shaped plate 31. The curved plate 31 of the pedal 3 for people to stand on is curved, which better fits the sole of the person's shoe and increases the standing area. At the same time, when the triangular ladder is used at different inclination angles, the curved plate 31 can ensure that there is always a positive upward surface, which improves the stability of the person when standing. In order to improve the anti-skid performance of the curved plate 31, a plurality of anti-skid convex strips 311 are provided on the surface of the curved plate 31. The anti-skid convex strips 311 extend along the length direction of the curved plate 31, and the cross-section of the anti-skid convex strips 311 is a curved surface.

[0028] like Figure 1As shown, the triangular ladder is connected with a limit chain 61, which is formed by connecting multiple metal rings. One end of the limit chain 61 is connected to the arc plate 31 of the middle section of the triangular ladder. The support tube 1 is provided with a limit hook 62 corresponding to the limit chain 61. When the support tube 1 is unfolded to a certain angle, the metal ring at the corresponding length on the limit chain 6 is buckled on the limit hook 62. Under the pulling force of the limit chain 61, the support tube 1 is limited so that it no longer moves outward, thereby improving the overall stability of the triangular ladder and the support tube 1 when in use. The triangular ladder is provided with a storage bayonet 81 corresponding to the support tube 1. The storage bayonet 81 is connected to the arc plate 31 of the lower section of the triangular ladder. The storage bayonet 81 is provided with a storage groove 811. After the support tube 1 is folded, it is snapped with the storage bayonet 81.

[0029] like Figure 1 As shown, the lower end of the support tube 1 is connected to a foot 11, and the lower end of the foot 11 is provided with four downward support blocks 101. The foot 11 can expand the support area of ​​the lower end of the support tube 1, prevent the support tube 1 from sinking into the soil, and improve the anti-skid effect of the lower end of the support tube 1. The lower end of the support tube 1 is detachably connected to a pad 7, the support tube 1 is a hollow tube, and the inner part of the support tube 1 near the lower end is connected to a connecting block 12, and the connecting block 12 is provided with a threaded hole. The pad 7 includes a threaded column 71 and a support plate 72. The support plate 72 is a circular plate, and the threaded column 71 is connected to the center of the support plate 72. The threaded column 71 is connected to the threaded hole on the connecting block 12 correspondingly, so that the pad 7 is connected to the support tube 1. The lower surface of the pad 7 is also provided with an anti-skid pad. The pad 7 is used to expand the support area of ​​the support tube 1 and better prevent sinking. At the same time, when used on a flat ground or indoors, the pad 7 can prevent slipping and protect the ground.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
