Description

Technical Field

[0001] This utility model relates to the field of forestry marking technology, and in particular to a portable tree marker for forestry. Background Technology

[0002] Tree marking is crucial for rational forest harvesting planning. Forestry workers can use marking to distinguish trees of different ages, species, and growth stages. For example, marking trees that have reached maturity for harvesting ensures that only suitable trees are felled during timber harvesting, avoiding over-harvesting of immature trees and thus achieving the sustainable use of forest resources.

[0003] Tree marking is typically done using a paint spraying machine, which is carried by a person on their shoulder strap and then sprayed through a nozzle.

[0004] The existing pigment spraying machine reduces sedimentation by stirring, but it is only a simple single-axis unidirectional stirring method, which cannot fully address the problems of pigment sedimentation and clumping. Especially for pigments that have been stored for a long time and have complex compositions, it is difficult to mix them evenly, resulting in unstable pigment concentration during spraying, mottled color and uneven thickness of the markings, which affects the quality and recognizability of the markings. Therefore, a portable tree marker for forestry is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable tree marker for forestry, which aims to improve the problem that the single stirring method in the prior art will cause sedimentation and affect the marking quality.

[0011] The bottom end of the support base is fixedly connected to the center of the top of the box, and the output end of the motor is rotatably connected to the inner wall of the top of the support base.

[0012] As a further description of the above technical solution:

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a portable tree marker for forestry, comprising a housing 1. The housing 1 can store corresponding pigments for marking trees. A button cover 4 is threaded to the top of the housing 1, facilitating manual rotation to open the housing 1 for refilling. A stirring mechanism 6 is located at the center of the top of the housing 1 to prevent pigment clumping. The stirring mechanism 6 includes a support base 601, with a motor 602 fixedly connected to the top of the support base 601, providing support for the motor 602. A fixing plate 604 is fixedly connected to the output end of the motor 602, and a fixing column 605 is fixedly connected to the bottom end of the fixing plate 604. Rotation of the output end of the motor 602 causes the fixing plate 604 and its fixing column 605 to rotate. A support column is fixedly connected to the inner side wall of the support base 601. 607, a rack 608 is slidably connected to the outer arc surface of the support column 607. The support column 607 can provide a certain support and guidance for the rack 608. The distance between the outer teeth of the two sets of racks 608 near the center is greater than that of the outer teeth far from the center, thereby changing the transmission ratio. A rotating gear 610 is rotatably connected to the top of the box 1. Two sets of racks 608 are provided, located on the front and rear sides of the rotating gear 610 respectively. A movable plate 606 is fixedly connected to the top of the rear rack 608. The movement of the movable plate 606 drives the rear rack 608 to move. A stirring shaft 603 is rotatably connected to the inner wall of the box 1. A rotating gear 609 is fixedly connected to the top of the stirring shaft 603. The two move along the same trajectory. A rotating component is provided on the inner wall of the stirring shaft 603. The rotating component can enhance the stirring effect. A fixing mechanism 7 is provided on the upper left side of the box 1.

[0035] Reference Figures 3-5The rotating assembly includes a stirring blade 614, the outer arc surface of which is rotatably connected to the inner wall of the stirring shaft 603. The rotation of the stirring blade 614 enhances the stirring effect. A support rod 611 is fixedly connected to the bottom of the inner wall of the housing 1. The support rod 611 is located inside the stirring shaft 603. A bevel gear 612 is fixedly connected to the outer wall of the support rod 611. Multiple sets of bevel gears 612 are provided. A bevel gear 612 is fixedly connected to the side of the stirring blade 614 near the support rod 611. 613, one set of bevel gear 612 corresponds to three sets of bevel gear 613. The bottom end of bevel gear 613 meshes with the top end of bevel gear 612. The meshing of the two allows bevel gear 613 to rotate. The bottom end of support base 601 is fixedly connected to the center of the top end of housing 1. The output end of motor 602 is rotatably connected to the inner wall of the top end of support base 601. Housing 1 provides support for support base 601. The rotation of the output end of motor 602 is set to avoid motion interference.

[0036] Reference Figures 3-5 The outer wall of the rotating gear 610 meshes with the outer wall of the rack 608. The meshing of the two drives the two sets of racks 608 to move alternately. The side of the rack 608 away from the rotating gear 610 meshes with the outer tooth surface of the rotating gear 609. The meshing of the two drives the rotating gear 609 to rotate. A guide groove is opened on the inner wall of the movable plate 606. The bottom end of the fixed column 605 contacts the inner wall of the guide groove. The guide groove is designed to avoid motion interference.

[0037] Reference Figure 1 and Figure 6 The front end of the box 1 is fixedly connected to a shoulder strap 3, which facilitates manual carrying of the box 1. The top rear side of the box 1 is fixedly connected to a handle 5, which facilitates manual lifting of the box 1. The left end of the box 1 is fixedly connected to a spray pipe 2, which is used to spray and mark trees. The fixing mechanism 7 includes a support block 701, the right end of which is fixedly connected to the upper left end of the box 1. The box 1 can fix and support the support block 701. The inner wall of the support block 701 is elastically connected to a limiting seat 702 through a connecting spring 703. The top end of the limiting seat 702 has an inclined surface facing upward. The rear end of the spray pipe 2 is fixedly connected to a connecting post 704. The rear end of the connecting post 704 is provided with a cross-shaped partition to prevent the spray pipe 2 from shaking and falling.

[0038] Reference Figure 6One end of the connecting spring 703 is fixedly connected to the outer wall of the limiting seat 702, and the other end of the connecting spring 703 is fixedly connected to the inner wall of the support block 701. The outer wall of the limiting seat 702 is slidably connected to the inner wall of the support block 701. The elasticity of the connecting spring 703 enables the limiting seat 702 to have the functions of reset and limiting. The outer arc surface of the connecting post 704 contacts the inner side wall of the support block 701, and the top end of the connecting post 704 contacts the bottom end of the limiting seat 702. The contact setting prevents the connecting post 704 from moving out.

[0039] Working principle: When marking is required, motor 602 is started. The output end of motor 602 drives the fixed plate 604 and fixed column 605 to rotate synchronously. The bottom end of fixed column 605 slides in the guide groove of movable plate 606, simultaneously pushing movable plate 606 to perform linear reciprocating motion. Movable plate 606 drives the rear rack 608 to move synchronously. Since rotating gear 610 meshes with the front and rear racks 608 respectively, when the rear rack 608 moves, it drives the front rack 608 to perform reciprocating horizontal motion through the transmission of rotating gear 610. The side of the two racks 608 away from rotating gear 610 meshes with rotating gear 609. The alternating motion of racks 608 causes rotating gear 609 to rotate continuously and stably in both directions. The top end of the stirring shaft 603 is fixedly connected, thereby driving the stirring shaft 603 to rotate in both directions on the inner wall of the box 1, stirring the pigment in the box. At the same time, inside the stirring shaft 603, under the meshing action of multiple sets of bevel gears 612 and 613, when the stirring shaft 603 rotates, bevel gear 612 drives bevel gear 613 to rotate, which in turn drives the stirring blade 614 to rotate on the inner wall of the stirring shaft 603. When the stirring shaft 603 rotates in the opposite direction, the corresponding stirring blade 614 will also rotate in the opposite direction. The special design of the external tooth spacing of the two sets of racks 608 (the external tooth spacing near the center is greater than the external tooth spacing far from the center, changing the transmission ratio) allows the rotating gear 609 to rotate multiple times in both directions when the output end of the motor 602 rotates once, enhancing the stirring effect.

[0040] The outer arc surface of the connecting column 704 contacts the inner side wall of the support block 701, and its top end rests on the bottom end of the limiting seat 702. Under the elastic force of the connecting spring 703, the limiting seat 702 always maintains the downward pressure limiting posture of the connecting column 704. Even if it encounters bumpy walking in the mountains or shaking of the equipment, it can effectively prevent the connecting column 704 from moving out and firmly fix the spray pipe 2. The limiting seat 702 uses a sloping design (the top end has an upward sloping surface, which makes it easy for the connecting column 704 to slide in and be positioned).

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
