Description

Technical Field

[0001] This utility model relates to the field of tree transportation technology, and in particular to a tree transportation device for forestry engineering. Background Technology

[0002] Forestry projects include forest area planning, forest cultivation, forest protection, and tree transplantation, and tree transplantation requires the use of transport devices to move the trees.

[0003] For example, Chinese patent application CN202420520945.5 discloses a tree transport device for forestry engineering. Specifically, it describes a system where a storage cylinder and a movable cylinder work together to store trees to be transported. An electric cylinder pushes a clamping rod to slide into the movable cylinder, causing a clamping plate to adhere to the surface of the tree, thus securing the tree inside the storage assembly. This prevents the tree from shaking during transport, which could damage branches or even cause it to tip over. An electric push rod drives an extension lug to move vertically, which, through a fixing ring, moves the movable cylinder vertically along the inner wall of the storage cylinder. This allows for adjustment of the height of the clamping assembly, making the device suitable for transporting trees of different heights. However, it has the following technical problems:

[0004] Before transporting trees, the above structure requires manual handling or crane lifting to place the trees in the middle of the movable cylinder. Manual handling is time-consuming and labor-intensive, and crane lifting requires manual support to stabilize the trees before they can be placed inside the movable cylinder. If the lifting rope breaks, the lifted trees could easily injure people. It is evident that the above structure is inconvenient for securing trees. Utility Model Content

[0005] To address the inconvenience of tree fixing methods mentioned in the background section, this utility model provides the following technical solution:

[0006] A tree transfer device for forestry engineering includes two mobile platforms;

[0007] The middle part of the mobile platform is equipped with a clamping structure for stabilizing the tree, and the upper end of the mobile platform is equipped with an adjustment structure for controlling the movement of the clamping structure.

[0008] The moving platform includes an arc-shaped limiting block. The outer wall of the arc-shaped limiting block is equipped with a lead screw for controlling the adjustment structure to move up and down. The outer wall of the arc-shaped limiting block has multiple positioning screw holes for positioning the clamping structure in conjunction with the adjustment structure.

[0009] Furthermore, the lower end of the movable platform is equipped with bolts for locking the two movable platforms, the lower end of the arc-shaped limiting block is equipped with a movable seat, and the outer wall of the arc-shaped limiting block is equipped with reinforcing ribs.

[0010] Furthermore, a connecting rod one is installed on one side of the arc-shaped limiting block, and two slots are opened on the side wall of the connecting rod one. A connecting rod two is installed on the other side of the arc-shaped limiting block, and a locking block for engaging with the slots is installed on one side of the connecting rod two. A limiting groove is opened at the upper end of the arc-shaped limiting block.

[0011] Furthermore, a connecting frame is installed on the outer wall of the arc-shaped limiting block, and the middle cavity of the connecting frame is connected to the limiting groove. A sliding groove is opened in the middle of the connecting frame, and a limiting rod for limiting the lead screw is installed at the lower end of the lead screw.

[0012] Furthermore, the clamping structure includes a clamping plate, and a sliding plate that slides within a limiting groove is installed on the outer wall of the clamping plate. Slider blocks are installed on both sides of one end of the sliding plate, and multiple ball bearings are installed at the upper and lower ends of the sliding plate.

[0013] Furthermore, the adjustment structure includes an arc-shaped frame, with a lead screw nut installed in the middle of the arc-shaped frame for cooperating with the lead screw to control the arc-shaped frame to move up and down, and a screw installed in the middle of the arc-shaped frame for cooperating with the positioning screw hole to position the arc-shaped frame.

[0014] Furthermore, pressure sleeves are installed at the lower ends of both sides of the arc-shaped frame, and a guide groove for sliding of the slider is opened in the middle of the pressure sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When two moving platforms are installed on both sides of the tree and fixed with bolts, rotating the lead screw causes the lead screw nut to move the arc frame downwards, and the pressure sleeve moves downwards simultaneously. The slider slides from one side of the guide groove towards the outer wall of the moving platform, causing the clamping plates to move closer to the tree in the middle of the moving platform and clamp the tree simultaneously. When the four clamping plates clamp the tree, they also lift the tree upwards, causing the bottom of the tree to leave the ground. Finally, the screw is screwed into the positioning screw hole, thereby fixing the position of the arc frame and fixing the height of the tree to facilitate the transfer of the tree. When the screw is screwed into the positioning screw hole, it can also reduce the wear of the lead screw and improve the service life of the lead screw. Attached Figure Description

[0025] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0026] Please see Figures 1-4 This utility model provides a tree transfer device for forestry engineering, including two moving platforms 100, four clamping structures 200, and two adjusting structures 300. Each moving platform 100 has two clamping structures 200 installed at its upper end. Bolts 10 for locking the two moving platforms 100 are installed at their lower ends. Before transferring the tree, the two moving platforms 100 are assembled and fixed together with the bolts 10, with the tree trunk positioned between the two moving platforms 100.

[0027] The movable platform 100 includes an arc-shaped limiting block 110, and a movable seat 111 is fixedly installed at the lower end of the arc-shaped limiting block 110. The movable seat 111 is an annular block. A reinforcing rib 112 is fixedly installed on the outer wall of the arc-shaped limiting block 110. The reinforcing rib 112 is used to increase the mechanical strength of the arc-shaped limiting block 110, making the arc-shaped limiting block 110 less prone to bending. A connecting rod 113 is fixedly installed on one side of the arc-shaped limiting block 110. Two slots 114 are opened on the side wall of the connecting rod 113. A connecting rod 2 115 is fixedly installed on the other side of the arc-shaped limiting block 110. A locking block 116 for engaging with the slot 114 is installed on one side of the connecting rod 2 115. Both the connecting rod 113 and the connecting rod 2 115 are fixedly installed on the upper end of the movable base 111. When the two movable platforms 100 are assembled together, one of the movable platforms 100 moves from top to bottom, so that the locking blocks 116 on one side of the two movable platforms 100 are respectively inserted into the slots 114. When the two movable bases 111 are aligned, the two movable bases 111 are fixed together with bolts, thus completing the fixation of the two movable platforms 100 and making the connection between the two movable platforms 100 more stable.

[0028] The upper end of the arc-shaped limiting block 110 has a limiting groove 118, which is an inclined groove. The horizontal height of the limiting groove 118 near the inner wall of the arc-shaped limiting block 110 is higher than the horizontal height of the limiting groove 118 near the outer wall of the arc-shaped limiting block 110. A connecting frame 120 is installed on the outer wall of the arc-shaped limiting block 110, and the middle cavity of the connecting frame 120 is connected to the limiting groove 118. The top wall and inner wall of the connecting frame 120 are inclined. A sliding groove 121 is provided in the middle of the connecting frame 120, and the inclination angle of the sliding groove 121 is the same as that of the limiting groove 118. The horizontal height of the side of the connecting frame 120 near the outer wall of the arc-shaped limiting block 110 is higher than the bottom wall of the side of the connecting frame 120 away from the arc-shaped limiting block 110. This allows the clamping structure 200 to move into the arc-shaped limiting block 110 and, while clamping the tree, also to give the tree an upward thrust, causing the bottom of the tree to gradually move away from the ground. This facilitates the movement of the universal wheels at the bottom of the moving seat 111, making it easier to transport the tree.

[0029] A clamping structure 200 for stabilizing trees is installed in the middle of the moving platform 100, and an adjustment structure 300 for controlling the movement of the clamping structure 200 is installed at the upper end of the moving platform 100. The clamping structure 200 includes a clamping plate 210, and a sliding plate 211 that slides within a limiting groove 118 is fixedly installed on the outer wall of the clamping plate 210. Slider blocks 212 are fixedly installed on both sides of one end of the sliding plate 211, and the sliding plate 211 slides within the connecting frame 120 and the limiting groove 118. The slider 212 slides within the sliding groove 121. Multiple ball bearings 213 are movably installed at the upper and lower ends of the sliding plate 211 to facilitate the sliding of the sliding plate 211 in the middle of the connecting frame 120 and prevent jamming.

[0030] The outer wall of the arc-shaped limiting block 110 is equipped with a lead screw 130 for controlling the up-and-down movement of the adjusting structure 300. A handwheel is installed at the upper end of the lead screw 130 to facilitate its rotation. A limiting rod 131 is fixedly installed at the lower end of the lead screw 130 to limit its movement. A limiting block is also installed on the outer wall of the arc-shaped limiting block 110 to limit the limiting rod 131, and the limiting rod 131 can rotate at the center of the limiting block. The outer wall of the arc-shaped limiting block 110 has multiple vertically oriented positioning screw holes 117 for positioning the clamping structure 200 in conjunction with the adjusting structure 300.

[0031] The adjustment structure 300 includes an arc-shaped frame 310. A screw nut 311 is fixedly installed in the middle of the arc-shaped frame 310 to cooperate with the screw 130 to control the arc-shaped frame 310 to move up and down. A screw 312 is installed in the middle of the arc-shaped frame 310 to cooperate with the positioning screw hole 117 to position the arc-shaped frame 310. Pressure sleeves 320 are fixedly installed at the lower ends of both sides of the arc-shaped frame 310. The pressure sleeves 320 are U-shaped blocks. A guide groove 321 for sliding of the slider 212 is opened in the middle of the pressure sleeve 320. The guide groove 321 is an inclined groove, and the horizontal height of the guide groove 321 near the outer wall of the moving table 100 is relatively high. When the pressure sleeve 320 moves downward, it presses down on the slider 212, causing the slider 212 to move towards the outer wall of the moving table 100, thereby driving the clamping structure 200 to move towards the middle of the moving table 100.

[0032] When the two moving platforms 100 are installed on both sides of the tree and fixed by bolts 10, the lead screw 130 is rotated, causing the lead screw nut 311 to drive the arc frame 310 to move downward. The pressure sleeve 320 moves downward simultaneously, and the slider 212 slides from one side of the guide groove 321 toward the outer wall of the moving platform 100, causing the clamping plate 210 to move closer to the tree in the middle of the moving platform 100 and clamp the tree simultaneously. When the four clamping plates 210 clamp the tree, they also lift the tree upward, so that the bottom of the tree is lifted off the ground. Finally, the screw 312 is screwed into the positioning screw hole 117, thereby fixing the position of the arc frame 310 and fixing the height of the tree to facilitate the transfer of the tree. When the screw 312 is screwed into the positioning screw hole 117, the wear of the lead screw 130 is also reduced, and the service life of the lead screw 130 is improved.

[0033] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
