Description

Technical Field

[0001] The invention relates to the field of forestry sapling transportation, and in particular to a forestry engineering sapling transportation device and method. Background Art

[0002] When managing forest land, forest rangers and other relevant management personnel usually conduct regular inspections of the forest land, and adjust the management and maintenance methods of the forest land in real time according to the actual conditions of the forest land. When trees in some areas of the forest land are cut down, seedlings die, or fires occur in the local area, resulting in dilution of trees, it is usually necessary to replant the seedlings bred in the nursery into the forest land to maintain the density of trees in the forest land. During the tree replanting process, due to the production and breeding of trees and plants in the forest land, large transport vehicles cannot go deep into the forest land. Usually, after the transport vehicles transport the seedlings to the edge of the forest land, the staff manually transports the seedlings to the replanting area and then carries out the replanting operation. When the seedlings are transported in batches manually, the seedlings are usually piled in transport boxes and bags. During transportation, the seedlings are piled up against each other, which not only makes the air permeability between the seedlings poor, but also squeezes each other, which can easily cause the seedlings to be damaged or destroyed.

[0003] In view of this, 1) Announcement No. CN216332236U discloses a forestry sapling transport vehicle, which includes a frame, a plurality of fixed cylinders are fixedly connected to the upper end of the frame, the fixed cylinders include support cylinders, the upper end of the support cylinders are fixedly connected to a top plate, the upper end of the top plate is rotatably connected to a rotating shaft, the rotating shaft is rotatably connected to a connecting rod, a ferrule is rotatably connected to the top plate, the ferrule is rotatably connected to the connecting rod, the connecting rod is slidably connected to a sliding sleeve, the upper end of the sliding sleeve is rotatably connected to the ferrule through a second rotating shaft, a side of the connecting rod close to the ferrule is rotatably connected to a roller, an opening is provided on the ferrule, and the connecting rod is located in the opening. The utility model can realize the fixation of saplings during transportation, and can better protect the roots of saplings at the same time.

[0004] 2) CN221843282U discloses a sapling transport rack for afforestation, which includes a fixed plate, three groups of slide grooves are opened through the upper and lower parts of the fixed plate, four groups of sliders are arranged through the slide grooves, three groups of threaded rods are arranged above each group of sliders, a fixing sleeve 2 is arranged at the lower position of the outer part of the threaded rod, and the fixing sleeve 2 is fixedly connected to the threaded rod, a collar is sleeved at the upper position of the outer part of the threaded rod, and a fixing sleeve 1 is fixedly connected to one side of the outer part of the collar, two groups of fixing sleeves 2 are fixedly installed at the lower position of the outer part of the threaded rod above the two groups of sliders located in the middle position, and two groups of symmetrical fixing sleeves 1 are arranged outside the collars of the six groups of threaded rods, the threaded rods are located above the fixed plate, and the size of the fixing sleeve 1 is smaller than that of the fixing sleeve 2. The sapling transport rack for afforestation described in the utility model can place saplings by category, and at the same time, it is convenient to place saplings of different heights, which is convenient to use.

[0005] 3) CN118255046A discloses a forestry planting, seedling transplanting and transport box, including a box body and a partition assembly. The present invention arranges a partition assembly. On the one hand, when storing and taking out the seedlings, the deformation and expansion of the box body and the partition assembly are utilized, so that the storage cavities opened on the multiple storage grids are arranged horizontally, which is convenient for storing the seedlings in the storage cavities. In the process of transportation, the relative movement of the two groups of storage grids in the partition assembly in the vertical direction causes the two groups of storage grids to be displaced in the vertical direction and partially overlap in the horizontal direction, which not only reduces the lateral width of the box body for easy transportation in the woodland, but also can flexibly adjust the size of the overlapping area of ​​the storage grids in the horizontal direction, thereby facilitating the adjustment of the density of the seedlings. Without affecting the ventilation and air permeability of the seedlings, the mutual restriction between the seedlings is utilized to increase the stability of the seedlings during transportation, thereby further enhancing the convenience of seedling transportation.

[0006] The above three types of transport devices all adopt a vertical method to transport the seedlings in a fixed manner, but the vertical method occupies a large space for seedlings, and only a small number of seedlings can be transported at one time. Moreover, when covering the sunshade, the crown of the evergreen broad-leaved seedlings is large, which makes it more troublesome to cover the sunshade; in addition, some seedlings have a large transpiration rate, and more root systems are damaged when the seedlings are lifted, so it is necessary to pay attention to moisturizing, but the above three types of transport devices are all innovative in the direction of how to fix the seedlings, resulting in ignoring the key point of moisturizing the seedlings to improve the survival rate. Based on this, the present invention proposes a forestry engineering seedling transport device and method, which relies on the improvement of the mountain transport vehicle, and can use the seedling placement module to switch the seedlings from longitudinal to horizontal placement, reducing the crown's occupation of the height space, and the seedling placement module can be loaded on the transport vehicle in a stacked manner, which can transport seedlings in large quantities and batches. Summary of the invention

[0007] The purpose of the present invention is to provide a forestry engineering sapling transportation device and method. The transportation device and method are improved based on a mountain transport vehicle. The sapling placement module can be used to switch the saplings from vertical to horizontal placement, thereby reducing the height space occupied by the crown.

[0008] To achieve the above object, the present invention provides the following technical solution: a forestry engineering sapling transportation device, comprising:

[0009] The transport vehicle comprises a frame, mountain wheels, a traction-type drag rod and a fence, wherein the mountain wheels are arranged on the bottom side of the frame, a traction-type drag rod is arranged on the front end of the frame, the traction-type drag rod can be connected to the trailer hook at the rear end of the agricultural machinery or tractor, and the upper side of the frame is surrounded by a fence; the fence is used to prevent the seedling placement module from collapsing during transportation, and the fence adopts a detachable structure, which can be conveniently taken out when the seedling placement module is transferred out of the frame;

[0010] The seedling placement module is provided with multiple modules and can be stacked and placed inside the fence of the transfer vehicle. The seedling placement module includes a frame, a sunshade unit, a switching unit and a seedling placement bin, wherein the top side and the front and rear sides of the frame are all opened, and the sunshade unit is installed on the top side of the frame; the seedling placement bin is provided with multiple modules, and the multiple seedling placement bins can be rotated with the switching unit to switch between horizontal and vertical states;

[0011] The humidification module is used to humidify the seedlings in the seedling placing bin when the seedling placing bin is switched from a vertical position to a horizontal position.

[0012] Preferably, the sun visor unit comprises an insert strip and a sun visor module, wherein the insert strip is distributed along both sides of the opening on the top side of the frame, and a plurality of sun visor modules can be slidably inserted into the inner side of the insert strip.

[0013] Preferably, there are multiple seedling placing bins, each of which is a rectangular bin with an open top, and the bin is used to place seedlings. At least two notches are provided on the top side of the seedling placing bin. Multiple seedling placing bins are rotatably installed side by side on the inner side of the frame, and an axle rod is provided on one side of each seedling placing bin.

[0014] Preferably, the switching unit is used to drive multiple seedling placement bins to rotate to achieve horizontal or vertical state switching of each seedling placement bin, and the switching unit includes a motor A, a rocker and a swing frame, wherein the shaft end of the motor A is connected to the rocker, the front end of the rocker is provided with a straight hole, the rear end of the swing frame is connected to the straight hole through a sliding shaft, and the front end of the swing frame is integrally formed with multiple sleeves, the number and position of the sleeves correspond to the shaft rod on one side of the seedling placement bin, the sleeves can be sleeved on the shaft rod, the sleeves rotate with the motor A and drive multiple seedling placement bins to rotate to switch the horizontal or vertical state. The main purpose of the switching unit is to switch the seedlings in the seedling placement bin from vertical to horizontal, mainly because: the crown of the seedlings is generally high, which will lift up the sunshade net / sunshade board, resulting in the inability to install the sunshade net. In addition, due to the problem of the crown, the placement bins cannot be stacked, resulting in only a small amount of seedlings being transported. Therefore, the switching unit is set to switch the seedlings to horizontal to ensure the installation of the sunshade net and the stacking of the seedling placement bins.

[0015] Preferably, the humidification module comprises a water tank, a humidification tube and a humidification unit, wherein a pump body is arranged inside the water tank, and an output end of the water tank is connected to the humidification unit through the humidification tube.

[0016] Preferably, the humidifying unit includes a support plate, a motor B, a gear and a humidifying head, wherein the support plate is fixed to the bottom side of the frame, a slide groove is arranged on the front side of the support plate, and the humidifying head can be slidably mounted on the slide groove; the motor B is mounted on the support plate, and the shaft end of the motor B is connected to a gear, which can mesh with a rack on one side of the humidifying head, and the gear can push the humidifying head to move upward and extend into the chamber of the seedling placement bin through the notch of the seedling placement bin. The humidifying unit can moisturize the seedlings and their root mud by atomizing or spraying water, and can improve the survival rate of seedling transportation in relatively dry weather (evergreen broad-leaved tree species have a large number of branches and leaves, and the transpiration volume is large, and more roots are damaged when the seedlings are lifted. After lifting and in the early stage of planting, the seedlings are prone to lose the water balance in the body, leading to death, so humidification operation is more necessary during transportation).

[0017] Preferably, water baffles are provided on the bottom edges of both sides of the frame, which can prevent water generated by the humidification module from overflowing from the frame. A small pump head can be arranged on the bottom side of the frame, and a filter can be arranged at the front end of the small pump head. The small pump head can be connected to the water tank through a hose, that is, it can cooperate with the barrier effect of the water baffle to filter and circulate the water to the water tank, thereby achieving a water-saving effect.

[0018] Preferably, there are also protrusions at intervals on both sides of the seedling placing bin, and the protrusions are provided with through holes. The two adjacent seedling placing modules are locked by a connecting piece, and the connecting piece is a U-shaped locking rod. The U-shaped locking rod can pass through the protrusions of the upper and lower seedling placing bins and be locked by a nut.

[0019] The present invention also provides a method for transporting saplings for forestry projects. The method is implemented based on the above-mentioned transport device. The specific method includes:

[0020] S1: Use a switching unit to switch the seedling placement bin from a horizontal position to a vertical position, and bundle multiple seedlings or pack single seedlings according to their sizes. Tightly tie the roots of the seedlings with straw ropes to ensure that the root system is intact, and place the multiple seedlings or packs of seedlings in the seedling placement bin;

[0021] S2: Use the switching unit to switch the seedling placement bin from a vertical position to a horizontal position, so that the crown of the seedling will not hit the sunshade net in the horizontal position;

[0022] S3: stacking multiple seedling placement modules along the inner side of the fence and locking them with connectors;

[0023] S4: Install a sunshade module on the topmost seedling placement bin, and slide the sunshade module onto the inner side of the cuttings;

[0024] S5: During transportation, the humidification module continuously uses gears to mesh the humidification head, so that the humidification head extends into the chamber through the notch of the seedling placement chamber to perform humidification operations. The water baffle on the lower side of the frame can prevent water from overflowing outside the frame;

[0025] S6: After the seedlings arrive at the destination, the downward movement of the humidifying head does not affect the switching of the seedling placement bins. First, the sunshade module on the top layer is removed, and then multiple seedling placement bins are lifted out of the transfer vehicle in order. Finally, the switching unit is used to switch the seedling placement bins from horizontal to vertical. At this time, the crowns of the seedlings are facing upwards and arranged neatly, which is convenient for picking up and planting.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

The two upper and lower adjacent seedling placement modules are locked by a connecting piece (14), and the connecting piece (14) is a U-shaped locking rod. The U-shaped locking rod can pass through the protrusions (13) of the upper and lower seedling placement bins (8) and be locked by a nut.

9. A method for transporting saplings for forestry projects, characterized by: The method is implemented based on a forestry engineering sapling transport device according to any one of claims 1 to 8, and the method comprises the steps of: S1: using a switching unit (7) to switch the seedling placement bin (8) from a horizontal position to a vertical position, bundling multiple seedlings or packaging single seedlings according to their sizes, tightly tying the roots of the seedlings with straw ropes to ensure that the root system is intact, and placing the multiple seedlings in bundles or packaging single seedlings in the seedling placement bin (8); S2: using a switching unit (7) to switch the seedling placement bin (8) from a vertical position to a horizontal position, so that the crown of the seedling will not hit the sunshade net in the horizontal position; S3: stacking a plurality of seedling placement modules along the inner side of the fence (4) and locking them with a connecting piece (14); S4: Install a sunshade module (602) on the topmost seedling placement bin (8), and slide the sunshade module (602) onto the inner side of the cutting strip (601); S5: During transportation, the humidification module continuously uses the gear (902) to mesh with the humidification head (903), so that the humidification head (903) extends into the chamber through the notch (801) of the seedling placement chamber (8) to perform a humidification operation, and the water baffle (12) on the lower side of the frame (5) can prevent water from overflowing outside the frame (5); S6: After the seedlings arrive at the destination, the downward movement of the humidifying head (903) does not affect the switching of the seedling storage bin (8). First, the sunshade module (602) on the top layer is removed, and then the multiple seedling storage bins (8) are lifted out of the transfer vehicle in order. Finally, the switching unit (7) is used to switch the seedling storage bin (8) from a horizontal position to a vertical position. At this time, the crowns of the seedlings are facing upwards and arranged neatly, which is convenient for picking up and planting.
