Description

Technical Field

[0001] This invention belongs to the technical field of branch transfer devices, specifically, it relates to an integrated device for the sand storage and transfer of yellow willow branches to prevent damage. Background Technology

[0002] In desert areas, afforestation and ecological restoration projects such as sand fixation are carried out. Due to its well-developed root system, drought resistance and wind and sand resistance, the yellow willow has become one of the core vegetation for improving sandy soil and curbing desertification. The quality of sand storage and translocation of its branches directly determines the survival rate of subsequent planting and the effectiveness of afforestation, which is a key link in the entire sand fixation project.

[0003] Currently, the demand for willow branches is increasing due to large-scale sand fixation and afforestation. However, the traditional sand storage and transportation of willow branches relies heavily on manual operation and lacks specialized integrated equipment, resulting in a crude operation process and many technical bottlenecks.

[0004] The core problems of traditional methods are concentrated in three aspects: First, the branch damage rate is high. There are no targeted fixation measures during manual filling and transportation, and the branches are easily squeezed and rubbed, resulting in epidermal damage, bud drop, and a high rate of mechanical damage. Second, the humidity control is unbalanced. The use of a single covering mode of all wet sand or all dry sand can easily lead to mold and rot of branches when covered with wet sand, while covering with dry sand can easily cause branches to dehydrate and shrivel, both of which seriously affect the vitality of branches. Third, the operation efficiency is low. The entire process from sand preparation and branch filling to transportation and loading depends on manual labor, which is difficult to match the demand for efficient operation in large-scale sand fixation and afforestation projects, thus restricting the progress of ecological restoration work. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a branch transfer device that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: an integrated device for the sand storage and transportation of *Salix matsudana* branches to prevent damage, comprising: A storage device, comprising multiple sets of storage boxes, the storage boxes being hollow and used to store willow branches; A fixing component is installed inside the storage box, and the fixing component is used to temporarily fix and limit the position of the willow branches inside the storage box; A wet sand container, used to fill a storage box with moist sand; A dry sand container, used to fill a storage box with dry sand; After placing the willow branches vertically in the storage box using the fixing components, moist sand is poured into the storage box through a wet sand container to cover the cut ends of the willow branches. Then, dry sand is poured on top of the moist sand through a dry sand container to cover the branches and trunks of the willow branches, thus completing the sand storage.

[0007] Furthermore, the fixing component includes two sets of semi-cylindrical shells, which can be spliced ​​together to form a complete cylindrical shell for placing willow branches.

[0008] Furthermore, a flip-top cover is rotatably connected to the bottom of the semi-cylindrical shell, and a magnet is installed on the flip-top cover, which is used to hold the bottom of the willow branch against the ground.

[0009] Furthermore, both the semi-cylindrical shell and the flip-top cover are provided with openings for sand flow.

[0010] Furthermore, a servo motor is fixedly connected to both the wet sand tank and the dry sand tank, and a stirring rod is fixedly connected to the output end of the servo motor. The stirring rod is used to stir the sand.

[0011] Furthermore, a slot is provided at the top opening of the storage box, and a rod (not shown in the figure) is inserted into the slot. The rod is used to connect two adjacent sets of storage boxes.

[0012] Furthermore, a support rod is fixedly connected to the top of the semi-cylindrical shell, and the support rod is used to temporarily install the semi-cylindrical shell inside the storage box.

[0013] Furthermore, there are two sets of base plates, located below the wet sand tank and the dry sand tank respectively. Each base plate is equipped with a conveyor belt, which is used to transport the mobile storage device and inject sand into the storage device.

[0014] Furthermore, a telescopic rod is installed at the bottom of the base plate. The telescopic end of the telescopic rod is fixedly connected to the base plate, and the other end of the telescopic rod is fixedly connected to the ground. The telescopic rod is used to move the base plate to facilitate the injection of sand into the storage device.

[0015] Furthermore, both the wet sand tank and the dry sand tank are equipped with solenoid valves at their bottom outlets, and cameras (not shown in the figure) are installed at the bottom outlets of both the wet sand tank and the dry sand tank. The cameras are used to detect the position of the storage device and then inject sand into different storage boxes.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention, through vertical fixing, layered sand injection, and automated positioning and control, can effectively reduce the mechanical damage rate of branches, accurately control the moisture of sand in different parts to take into account both rooting needs and anti-mildew effects, realize integrated operation of sand storage and transportation, improve work efficiency, and at the same time ensure the survival rate of subsequent planting of branches, providing efficient and reliable technical support for large-scale sand fixation and afforestation projects.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Example: Refer to Figure 1-8 An integrated device for preventing damage during sand storage and transporting of willow branches includes: The storage device includes multiple sets of storage boxes 1, each hollow, for storing willow branches. Healthy 1-2 year old willow branches are selected and cut into 80-100cm lengths (0.8-1.5cm in diameter; this size of branch has the strongest rooting ability). The cuts are made at a 45° angle and smoothed (to reduce the area susceptible to pathogen infection). The branches are then immersed in an 800-fold dilution of carbendazim for 5 minutes to disinfect (to kill saprophytic bacteria on the cut surface and reduce the risk of mold). After removal, they are air-dried in a cool, ventilated place (avoiding direct sunlight to prevent dehydration of the epidermis) for later use. A fixing component is installed inside the storage box 1. The fixing component is used to temporarily fix and limit the yellow willow branches inside the storage box 1. Wet sand container 5 is used to fill storage box 1 with moist sand. The wet sand is prepared as follows: based on the humidity requirements (70-75%) for rooting of willow branch cuts, fill wet sand container 5 with a mixed substrate (70% river sand + 20% humus + 10% perlite), with a total mass of 500 kg; add 125 kg of clean water through the metered water inlet on the top of the container (water accounts for 25% of the total substrate mass; this ratio has been verified by experiments to consistently achieve the standard of "forming a clump when squeezed in the hand, but not crumbling when released"); use a hygrometer inserted deep into the substrate to check the humidity to ensure uniformity (error ≤3%). Dry sand container 6 is used to inject dry sand into storage box 1. To meet the slightly moist requirement (60-65%) for preventing mold growth on the trunk of the willow branches, 500 kg of clean river sand with a particle size of 0.1-0.5 mm is injected into dry sand container 6, along with 30 kg of clean water (water accounts for 6% of the total mass of the river sand). Ensure that the sand meets the standard of "scattering easily when released and without obvious dust" to avoid the sand being too dry, which would cause dehydration of the branches, or too wet, which would induce mold growth. After placing the willow branches vertically in storage box 1 using the fixing components, moist sand is poured into storage box 1 through wet sand container 5 to cover the cut of the willow branches. Then, dry sand is poured on top of the moist sand through dry sand container 6 to cover the trunk of the willow branches, thus completing the sand storage.

[0021] The fixing component includes two sets of semi-cylindrical shells 2, which can be spliced ​​together to form a complete cylindrical shell for placing willow branches.

[0022] The bottom of the semi-cylindrical shell 2 is rotatably connected to a flip-top cover 3, and a magnet 4 is installed on the flip-top cover 3. The flip-top cover 3 is used to hold the bottom of the willow branch.

[0023] Both the semi-cylindrical shell 2 and the flip-top cover 3 are provided with openings for sand flow.

[0024] Both the wet sand tank 5 and the dry sand tank 6 are fixedly connected to a servo motor 701. A stirring rod 702 is fixedly connected to the output end of the servo motor 701. The stirring rod 702 is used to stir the sand.

[0025] A slot 101 is provided at the top opening of the storage box 1, and a plug rod is inserted into the slot 101. The plug rod is used to connect two adjacent sets of storage boxes 1.

[0026] A support rod is fixedly connected to the top of the semi-cylindrical shell 2. The support rod is used to temporarily install the semi-cylindrical shell 2 inside the storage box 1.

[0027] It also includes: two sets of base plates 801, which are located below the wet sand tank 5 and the dry sand tank 6 respectively. Each base plate 801 is equipped with a conveyor belt 9, which is used to transport the mobile storage device and inject sand into the storage device.

[0028] A telescopic rod 802 is installed at the bottom of the base plate 801. The telescopic end of the telescopic rod 802 is fixedly connected to the base plate 801, and the other end of the telescopic rod 802 is fixedly connected to the ground. The telescopic rod 802 is used to move the base plate 801 to facilitate the injection of sand into the storage device.

[0029] Both wet sand tank 5 and dry sand tank 6 are equipped with solenoid valves at their bottom outlets, and cameras are installed at the bottom outlets of both tanks. When the camera detects that storage box 1 is in place, it automatically triggers the opening of the solenoid valve at the bottom of the wet sand tank, injecting wet sand into the storage box. The sand injection speed is controlled at 5 kg / min (to avoid the flow rate being too fast and impacting the branches), until the wet sand completely covers the 5-10 cm cut area at the bottom of the branch (the sand injection amount is about 20 kg / set of storage boxes, controlled by the flow count of the solenoid valve). After the sand injection is completed, the solenoid valve automatically closes. At the same time, after the camera is positioned, it triggers the opening of the solenoid valve of dry sand tank 6, injecting dry sand at a speed of 8 kg / min, until the dry sand completely covers the branch trunk.

[0030] Of particular note is: 1. When mixing sand, the humidity should be monitored in real time to avoid humidity deviation caused by changes in ambient temperature (such as high temperature evaporation). If the humidity is insufficient, a small amount of water can be added and the mixture can be stirred again; if the humidity is too high, dry matrix should be added to adjust it.

[0031] 2. When filling the branches, ensure that the buds are facing upwards to avoid the buds being covered or squeezed by the sand, which would reduce the germination rate; the insertion depth of the branches should be uniform (the bottom should be against the flipped bottom cover) to ensure that the wet sand evenly covers the cut.

[0032] 3. During the sand injection process, the camera must monitor the entire process. If the solenoid valve malfunctions (such as being unable to close), immediately cut off the power and manually close the mechanical valve to prevent excessive accumulation of sand.

[0033] 4. During long-distance transportation, it is necessary to avoid severe weather such as heavy rain, high temperature (>25℃), and strong wind (>6 level). In case of special weather, insulation and rainproof facilities should be installed in the carriage to protect the branches.

[0034] 5. During equipment maintenance, components such as sand tanks and conveyor belts need to be fully inspected regularly (every 10 uses), servo motors need to be lubricated, and solenoid valves need to have their valve cores cleaned of impurities to ensure long-term stable operation of the equipment.

[0035] When using it, please refer to the following operating steps: Step 1: Equipment Preparation and Debugging 1. Component Inspection and Assembly: Inspect the integrity of core components such as storage box 1, fixing components (semi-cylindrical shell 2, flip-top cover 3), wet sand tank 5, dry sand tank 6, conveyor belt 9, and telescopic rod 802 one by one, to ensure that the semi-cylindrical shell 2 and flip-top cover 3 rotate smoothly, the magnet 4 is firmly attached, and the solenoid valves of wet sand tank 5 and dry sand tank 6 operate flexibly.

[0036] 2. Position and height calibration: By controlling the extension and retraction of the telescopic rod 802, adjust the height of the two sets of bottom plates 801 under the wet sand tank 5 and the dry sand tank 6 to be flush with the top of the storage box 1 to be used (error ≤2cm), to ensure that the discharge port is precisely aligned with the opening of the storage box 1 when filling sand; start the camera and calibrate its positioning function to ensure that the position of the storage box 1 can be clearly identified to avoid sand filling deviation.

[0037] 3. Conveyor belt debugging: Start the conveyor belt 9, set the running speed to 0.5m / s, and test its conveying stability; adjust the relative position of the conveyor belt 9 and the sand tank outlet to ensure that the outlet of the storage box 1 can be continuously aligned with the opening area of ​​the storage box 1 when the storage box 1 moves on the conveyor belt.

[0038] 4. Circuit and power debugging: Connect the power supply to the servo motor 701, solenoid valve and camera, test the rotational stability of the stirring rod 702 driven by the servo motor 701 (speed set to 60r / min), check the on and off response speed of the solenoid valve, and ensure that the camera image is clear and the positioning signal transmission is normal.

[0039] Step 2: Sand Mixing and Pre-storage 1. Wet sand preparation: Pour the pre-mixed substrate (70% river sand + 20% humus + 10% perlite) into wet sand tank 5. Add water at a ratio of 25% based on the total mass of the substrate (e.g., 125kg water for 500kg substrate). Start the servo motor 701 and drive the stirring rod 702 to stir for 15 minutes to fully mix the water and substrate. After stirring, let it stand for 5 minutes. The final wet sand should reach the standard of "forming a clump when squeezed in the hand and not crumbling when released" (corresponding to a humidity of 70-75%).

[0040] 2. Dry sand preparation: Pour clean river sand with a particle size of 0.1-0.5mm into the dry sand tank 6, and add clean water at a ratio of 6% according to the total mass of the river sand (e.g., 30kg of clean water for 500kg of river sand); start the servo motor 701 to drive the stirring rod 702 to stir for 10 minutes to ensure uniform humidity. The final dry sand humidity should reach the standard of "sprinkles easily when released and has no obvious dust" (corresponding to a humidity of 60-65%).

[0041] 3. Sand pre-storage: After the mixing is completed, close the solenoid valves of wet sand tank 5 and dry sand tank 6, and pre-store the mixed wet sand and dry sand in the tanks for later use.

[0042] Step 3: Assembly of storage box connection and fixing components 1. Series connection of storage boxes: Based on the number of sand-stored branches, take the corresponding number of storage boxes 1, insert the insertion rod into the slot 101 at the top opening of the storage box 1 to achieve series connection and fixation of adjacent storage boxes 1; in this embodiment, 5 groups are connected in a column, and a total of 4 columns are connected (the number of columns can be adjusted according to actual transportation needs).

[0043] 2. Assembly of fixed components: The two sets of semi-cylindrical shells 2 are spliced ​​together to form a complete cylindrical shell. The flip-top cover 3 is attached to the bottom of the cylindrical shell by rotation and the magnetic force of the magnet 4 is used to achieve temporary fixation, forming a temporary fixing cavity with "open top and closed bottom". Check whether the sand flow openings on the semi-cylindrical shell 2 and the flip-top cover 3 are unobstructed to avoid blockage.

[0044] 3. Installation of fixing components: Using the support rod at the top of the semi-cylindrical shell 2, temporarily snap the assembled fixing components to the edge of the top opening of the storage box 1. The fixing components are evenly arranged in each group of storage boxes 1 (5cm apart), ensuring that the axis of the cylindrical shell of the fixing components is perpendicular to the bottom surface of the storage box 1.

[0045] Step 4: Filling and Vertical Positioning with Yellow Willow Branches 1. Branch pretreatment: Select healthy 1-2 year old yellow willow branches, cut them into 80-100cm lengths (0.8-1.5cm in diameter), make the cuts at a 45° angle and smooth them, disinfect them with 800 times diluted carbendazim solution for 5 minutes, and let them dry for later use.

[0046] 2. Vertical filling: Insert the pre-treated willow branches vertically into the cylindrical shell of the fixing component one by one, ensuring that the bottom of the branch is tightly against the flip-top cover 3, the vertical angle between the branch axis and the bottom surface of the storage box 1 is ≥85°, and the buds are facing upwards; avoid violent friction between the branches and the inner wall of the cylindrical shell during the filling process to prevent damage to the epidermis.

[0047] Step 5: Layered sand filling (wet sand covering the cut + dry sand covering the branches) 1. Wet sand injection: Place the series-connected storage box group on the conveyor belt 9, start the conveyor belt 9 to transport it to the bottom of the wet sand tank 5; after the camera detects that the storage box 1 is in place, it automatically triggers the solenoid valve at the bottom of the wet sand tank 5 to open, injecting wet sand into the storage box 1 until the wet sand completely covers the 5-10cm cut area at the bottom of the willow branch (the amount of sand injected is about 20kg / set of storage box); after the sand injection is completed, the solenoid valve automatically closes.

[0048] 2. Dry sand injection: Conveyor belt 9 continues to transport the storage box group to the bottom of dry sand tank 6. After the camera is positioned, the solenoid valve of dry sand tank 6 is triggered to open, and dry sand is injected into the storage box 1 until the dry sand completely covers the branches of the willow branches (with no branches exposed, and the amount of sand injected is about 30kg / group of storage boxes). During the sand injection process, the sand injection progress can be observed in real time through the camera to avoid insufficient or excessive sand injection.

[0049] Step Six: Separate the Fixing Components 1. Component Removal: After all storage boxes 1 have been filled with sand, the conveyor belt 9 transports the storage box assembly to the designated work station; the operator holds the support rod at the top of the fixed component and pulls it vertically upward to remove the semi-cylindrical shell 2 from the storage box 1 as a whole.

[0050] 2. Bottom cover separation: After the semi-cylindrical shell 2 is removed, the bottom cover 3, due to the loss of the support and constraint of the cylindrical shell, flips downward under its own weight and the pressure of the sand. The magnet 4 is released from the adsorption state, realizing the natural separation from the bottom of the willow branch. After separation, the sand remaining in the bottom cover 3 can fall into the storage box 1 through the opening, avoiding waste.

[0051] Step Seven: Transshipment Preparation and Transportation 1. Transfer station docking: Adjust the height of the base plate 801 by using the telescopic rod 802 to make the height of the conveyor belt 9 match the height of the truck bed, and transport the storage box group to the end of the conveyor belt 9.

[0052] 2. Loading and securing: Use a forklift to transfer the tandem storage box assembly along with the bottom pallet into the transport truck, ensuring that the storage box assembly is placed stably; if necessary, ropes can be used for additional securing to prevent shaking during transportation.

[0053] 3. Transportation Management: During transportation, the vehicle speed on paved roads should be controlled at ≤60km / h, and the vehicle speed on bumpy roads should be ≤30km / h. Sudden braking and sharp turns should be avoided. After arriving at the planting site, the cuttings should be removed and inserted within 24 hours.

[0054] Step 8: Device Cleaning and Reset 1. Component cleaning: Clean the removed semi-cylindrical shell 2, flip-top cover 3, plug rod and other components to remove residual sand from the surface, and check whether the magnet 4, rotating connection and other parts are intact.

[0055] 2. Device reset: Turn off all power, retract the telescopic rod 802 to the initial position, reset the conveyor belt 9, clean the wet sand tank 5 and dry sand tank 6 and set them aside, thus completing the entire operation process.

[0056] This invention, through its design of vertical fixation, layered sand injection, and automated positioning and control, can effectively reduce the mechanical damage rate of branches, precisely control the moisture content of sand in different parts to balance rooting needs and mold prevention, realize integrated sand storage and transportation operations, improve operational efficiency, and ensure the survival rate of branches after subsequent planting, providing efficient and reliable technical support for large-scale sand fixation and afforestation projects.
