Description

Technical Field

[0001] The utility model belongs to the technical field of tree planting, and in particular relates to a tree planting depth control device. Background Art

[0002] Forestry is the practice of using trees, shrubs, and vines for production, providing timber, fuel, food, furniture, handicrafts, and other products. Forestry not only provides a wealth of ecological products, such as timber, medicinal herbs, and edible fungi, but also serves important ecological functions, such as soil and water conservation, windbreak and sand fixation, and farmland protection.

[0003] Currently, when planting trees, especially large container seedlings, soil ball seedlings, and rare seedlings, a pit must be dug, the roots of the trees buried in the pit, the trees manually straightened, and then backfilled with soil. However, this planting method does not control the planting depth of the trees. Planting too shallow or too deep can lead to slow growth, injury, or even death of the trees. Therefore, we have proposed a tree planting depth control device to address this problem. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing planting method does not control the planting depth of trees, and too shallow or too deep planting depth may cause slow growth, injury or death of trees.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] A tree planting depth control device includes a support frame with an opening on one side for trees to pass through, a lifting mechanism for lifting trees, and a limiting mechanism for preventing trees from tilting when lifted. The lifting mechanism and the limiting mechanism are both arranged on the support frame. The lifting mechanism includes a mounting seat, a rotating rod, a pull rope and a binding strap. The mounting seat is arranged at the upper end of the support frame, the rotating rod is rotatably installed at the lower end of the support frame, the pull rope is fixedly installed at the end of the rotating rod, and the binding strap is fixedly installed at one end of the pull rope.

[0007] The mounting base is further defined as being provided with an adapter post, on which a rotating support bar is rotatably mounted, and the rotating rod is provided with a plurality of slots that mate with the ends of the rotating support bar. With this structural design, the rotating support bar mates with the slots on the rotating rod, allowing the rotating rod to be locked at different angles to lock the lifting height, providing greater convenience during use.

[0008] The lockhole that is formed on the first rotatable plate is formed on the second rotatable plate, and the lockhole that is formed on the second rotatable plate is formed on the second rotatable plate. With this structural design, when the tree trunk is stuck between the first fixed plate and the second fixed plate, the rotating plate is pushed to rotate until one side of the rotating plate is close to the trunk. The limit block is pulled tightly against the side of the second fixed plate by the cutting and the tension spring. At this time, the locking bolt is tightened, and the limit block, cutting and rotating plate are locked in the rotation angle as a whole. The first fixed plate, the second fixed plate and the rotating plate have a limiting effect on the tree trunk, preventing the tree from tilting when lifted and affecting planting.

[0009] It is further defined that the locking bolt is provided with a through hole, and a force-bearing rod is movably inserted into the through hole. Such a structural design saves effort when rotating the locking bolt through the force-bearing rod, and is more convenient to use.

[0010] Furthermore, the first fixed plate, the second fixed plate, and the rotating plate are each rotatably mounted with a rotating roller on one side thereof adjacent to each other. With this structural design, the rotating roller can reduce friction between the tree trunk and the first fixed plate, the second fixed plate, and the rotating plate, thereby preventing the tree trunk from becoming stuck during the lifting process.

[0011] It is further defined that a roller is rotatably mounted on the lower end of the support frame, and a handle is provided on the upper portion of the support frame. Such a structural design, with the handle and the roller, makes it easier to move the support frame.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] According to the utility model, after the roots of the trees are placed in the earth pit, the support frame is moved to the outside of the tree, the trunk is tied tightly with a strap, and then force is applied to press down the end of the rotating rod. According to the lever principle, the other end of the rotating rod will lift the tree upwards through the pull rope and the strap. With the cooperation of the limiting mechanism, the tree will be lifted vertically upwards until the roots of the tree are at a depth suitable for planting. At this time, the soil can be backfilled to complete the planting of the tree. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The limiting mechanism includes a first fixed plate 6, a second fixed plate 61, a rotating plate 62, two insertion strips 63, a fixing column and a locking bolt 65. The first fixed plate 6 and the second fixed plate 61 are fixedly mounted on the support frame 1. The first fixed plate 6 and the second fixed plate 61 are connected to one end of the support frame 1, and the whole is V-shaped. The other ends of the first fixed plate 6 and the second fixed plate 61 face the opening of the support frame 1. The rotating plate 62 is rotatably mounted on the first fixed plate 6. The rotating plate 62 is provided with two slots away from the adapter end. The two insertion strips 63 are movably inserted into the two slots. A tension spring is provided between the two insertion strips 63 and the two slot walls. The insertion strips 63 are pulled by the tension spring to make the insertion strips The limit block 64 on the fixing column at the end of the strip 63 maintains a fitting relationship with the second fixing plate 61, which is more convenient to use. The fixing column is fixedly installed between the two insertion strips 63, and the fixing column is located at the ends of the two insertion strips 63. The limit block 64 is rotatably installed on the fixing column. The limit block 64 is provided with at least one flat surface. When the rotating plate 62 rotates to the side of the second fixing plate 61, the flat surface of the limit block 64 is in close contact with the side surface of the second fixing plate 61. A clearance groove 621 is provided at the end of the rotating plate 62 close to the fixing column. A threaded groove connected to the slot is provided on the rotating plate 62.

[0032] The method of using the utility model is as follows:

[0033] The tree is placed in the dug pit, and the support frame 1 is pulled to the outside of the forest so that the tree is located between the first fixing plate 6 and the second fixing plate 61, and the trunk is close to the rotating roller. Then the rotating plate 62 is rotated so that the rotating roller on the side of the rotating plate 62 is close to the trunk. During this process, the limit block 64 moves along the second fixing plate 61, and the plane of the limit block 64 is in close contact with the side of the second fixing plate 61. The cutting strip 63 moves in the slot according to the rotation angle of the rotating plate 62. At this time, the locking bolt 65 is rotated by the force rod 651 so that the end of the locking bolt 65 contacts the cutting strip 63 and presses it tightly. The rotating plate 62, the cutting strip 63 and the limit block 64 as a whole enclose the trunk with the first fixing plate 6 and the second fixing plate 61, thereby limiting the trunk and preventing the trunk from tilting.

[0034] Tie the lower part of the trunk tightly with the strap 5, and apply force to press the end of the rotating rod 3 downward, so that the end of the strap 5 moves upward under the action of the force, lifting the tree upward so that its roots are at a suitable height;

[0035] When the end of the rotating rod 3 rotates under downward pressure, the rotating support bar 21 rotates under the action of gravity, and the ends of the rotating support bar 21 are successively inserted into the card slot 31. When the rotating rod 3 stops rotating, the rotating support bar 21 can limit the rotating rod 3, so that the rotating rod 3 maintains the rotation angle, and the tree can be locked at the lifting height, which is convenient for backfilling the root soil and more convenient for planting.

[0036] The above describes in detail the tree planting depth control device provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concept of the present invention.
