Description

Technical Field

[0001] The invention relates to a forest tree breeding device, and in particular to a mobile sapling transplanting protection device and method for forestry afforestation. Background Art

[0002] In forest breeding, seedlings cultivated by sowing or vegetative propagation have a high density and each seedling occupies a small nutritional space. To cultivate large seedlings, they must be transplanted. According to the requirements of landscape greening for seedlings of various specifications and the need for cultivation methods, they can be transplanted once or multiple times. Transplantation can expand the nutritional space for seedling growth, such as light space, ventilation space, and branch growth space, as well as the space for root growth, water and nutrition absorption. Pruning the roots during transplanting can also stimulate the development of the seedling root system, grow more fibrous roots, and improve the greening survival rate. When transplanting seedlings, it is usually necessary to use corresponding protective devices to temporarily fix the transplanted seedlings to prevent them from falling over.

[0003] At present, there are still some defects and deficiencies in the use of the seedling transplanting protection device for forestry afforestation. The specific areas that need to be improved are as follows:

[0004] 1. Most of the existing sapling transplant protection devices for forestry only have the function of supporting transplanted saplings. When in use, they cannot assist users in moving and transporting saplings. In addition, the existing devices are large in size and inconvenient to move themselves when in use.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention is provided with a groove, a support shaft, a support rod and a universal wheel on the bottom surface of the base, and a placing mechanism is provided above the base. When using the device for auxiliary work of transplanting saplings, the user can place the saplings to be transplanted on the two clamping plates. At this time, multiple universal wheel moving devices can be used to move the saplings and transport them to the transplanting location, so that the user can move the saplings with large volume and heavy weight. The multiple universal wheels also make it convenient for the user to move and transport the device body, which further improves the convenience of using the device.

[0027] 2. The present invention is connected with the base and the placement mechanism by setting a moisturizing mechanism. When using the device to transport saplings, the user can use screws, threaded hole 1 and threaded hole 3 to install and fix the mounting plate and the support plate on the right side of the placement plate. When transporting the saplings, the soil at the root of the saplings can be placed on the support plate, and then the user can control the water pump to work through the controller. When the water pump is working, the clean water or nutrient solution in the liquid storage tank is sucked out through the internal threaded pipe, the external threaded pipe 1 and the connecting hose 1 and input into the nozzle. Then the atomizing nozzle on the nozzle atomizes the clean water and the nutrient solution and sprays them on the roots of the saplings to moisturize the roots of the saplings, thereby avoiding the drying of the soil at the roots of the saplings during the transportation of the saplings, resulting in water shortage at the roots of the saplings, which affects the survival rate of subsequent transplanting.

[0028] 3. The present invention is connected with the base by setting a placement mechanism and a clamping mechanism. When transporting the saplings, the placement mechanism can be used to lift and support the saplings. When the saplings need to be supported by the device after transplanting, the user can rotate the worm gear 2 to drive the rotating shaft, the slider and the placement plate to rotate 180 degrees so that the clamping plate 2 rotates to the lower side of the placement plate. Then, the user can rotate the screw rod 2 to drive the slider and the sliding plate to move backwards through the threaded hole 4 so that the sliding plate moves to the rear end of the placement plate. At this time, the user can push the device to flip counterclockwise to make the device stand upright. At this time, the base and the placement plate are turned back. The left side of the board is in contact with the ground, and the sapling is located between the first and second splints, and the sapling is in contact with the second splint. At this time, the user can rotate one of the lead screws to use the sprocket one to drive the other side lead screw to rotate forward. When the lead screw rotates forward, it drives the nuts on the left and right sides to approach each other, so that the telescopic connecting rod unfolds and pushes the first splint toward the sapling. When the first splint is in contact with the sapling, the lead screw is stopped from rotating, so that the sapling is supported and fixed by the first and second splints, thereby preventing the sapling from tipping over when it is just transplanted and affecting the survival rate of transplantation, further increasing the functionality of the device and enriching the usage of the device.

[0029] 4. The present invention is connected with the base and the placement mechanism by setting a fixing mechanism. When the device is erected to support the sapling, the user can control the motor to drive the screw rod 1 to rotate forward through the controller. When the screw rod 1 rotates forward, it drives the fixing plate 3 and the cutting rod to descend through the threaded hole 2 so that the cutting rod is inserted into the ground to fix the device body, thereby improving the supporting effect of the device on the sapling. After the cutting rod is inserted into the soil, the user can rotate the worm gear 1 to drive the connecting shaft and the cam to rotate. When the raised end of the cam rotates upward and gradually separates from the fixing plate 5, the spring elastic force pushes the fixing plate 5 Move upward to make the blocking rod disengage from the seepage hole and open the seepage hole. Then the user can rotate the external threaded tube one to make it disengage from the internal threaded tube, and connect one of the external threaded tubes two with the internal threaded tube. At this time, control the water pump to make the water or nutrient solution in the liquid storage tank be input into multiple installation cavities through the internal threaded tube, the external threaded tube two, the connecting hose two, the diversion pipe, and the connecting pipe. Then the clean water or nutrient solution flows out through the seepage hole and seeps into the soil around the roots of the seedlings, thereby directly irrigating the roots of the seedlings, improving the irrigation effect, reducing the amount of irrigation water, saving water resources, and further increasing the functionality of the device.

[0060] The operating steps of the present invention are:

[0061] When using the device to transport the seedlings to be transplanted, the user can use the screws 412, the threaded hole 1 413 and the threaded hole 3 94 to install and fix the mounting plate 411 and the support plate 47 on the right side of the placement plate 91. When transporting the seedlings, the seedlings to be transplanted can be placed on the two clamping plates 2 93, and the soil at the roots of the seedlings can be placed in the support plate 47. Then the user can control the water pump 44 to work through the controller 5. When the water pump 44 works, the clean water or nutrient solution in the liquid storage tank 41 is sucked out through the internal threaded pipe 414, the external threaded pipe 1 45 and the connecting hose 1 46 and input into the nozzle 49.

When the first clamping plate 74 fits the sapling, the lead screw 72 is stopped, so that the sapling is supported and fixed by the first clamping plate 74 and the second clamping plate 93.

[0063] When the device is erected to support the sapling, the user can control the motor 86 through the controller 5 to drive the screw 1 82 to rotate forward. When the screw 1 82 rotates forward, it drives the fixing plate 3 83 and the cutting rod 812 to descend through the threaded hole 2 84 so that the cutting rod 812 is inserted into the ground to fix the device body. After the cutting rod 812 is inserted into the soil, the user can rotate the worm 1 818 to use the worm gear 1 817 to drive the connecting shaft 815 and the cam 814 to rotate. When the raised end of the cam 814 rotates upward and gradually disengages from the fixing plate 5 816, the elastic force of the spring 819 pushes the fixing plate 5 816 to move upward The blocking rod 821 is separated from the seepage hole 822 to open the seepage hole 822, and then the user can rotate the external threaded tube 45 to separate the external threaded tube 45 from the internal threaded tube 414, and connect one of the external threaded tubes 87 to the internal threaded tube 414. At this time, the water pump 44 is controlled to work so that the water or nutrient solution in the liquid storage tank 41 is input into the multiple installation cavities 813 through the internal threaded tube 414, the external threaded tube 87, the connecting hose 88, the diversion pipe 810, and the connecting pipe 811, and then the clean water or nutrient solution flows out through the seepage hole 822 and seeps into the soil around the roots of the seedlings, thereby directly irrigating the roots of the seedlings.

When using the device to transport a sapling to be transplanted, the user can use the screw (412), the threaded hole 1 (413) and the threaded hole 3 (94) to install and fix the mounting plate (411) and the support plate (47) on the right side of the placement plate (91). When transporting the sapling, the sapling to be transplanted can be placed on the two clamping plates 2 (93), and the soil at the root of the sapling can be placed in the support plate (47). Then, the user can control the water pump (44) to work through the controller (5). When the water pump (44) is working, The clean water or nutrient solution in the liquid storage tank (41) is sucked out through the internal threaded tube (414), the external threaded tube (45) and the connecting hose (46) and input into the nozzle (49), and then the atomizing nozzle on the nozzle (49) atomizes the clean water and nutrient solution and sprays them on the roots of the seedlings to moisturize the roots of the seedlings. At this time, the seedlings can be moved by using a plurality of universal wheel (3) moving devices to move the seedlings to a transplanting location, and then the seedlings can be removed from the second clamping plate (93) and the supporting plate (47) for transplanting; S2. When the device is needed to support the saplings after transplanting, the user can rotate the worm gear 3 (13) and use the worm gear 3 (14) to drive the support shafts (11) on both sides to rotate relative to each other, so that the left and right support rods (2) and the universal wheel (3) are rotated into the groove (10) for storage. At this time, the user can rotate the screw (412) to remove the mounting plate (411) and the support plate (47) from the placement plate (91), and rotate the worm gear 2 (98) and use the worm gear 2 (912) to drive the rotating shaft (911), the slider (914) and the placement plate (91) to rotate 180 degrees so that the clamping plate 2 (93) rotates to the lower side of the placement plate (91). Then, the user can rotate the screw rod 2 (913) and use the threaded hole 4 (915) to drive the slider (914) and the sliding plate (96). The backward movement causes the sliding plate (96) to move to the rear end of the placement plate (91). At this time, the user can push the device to flip counterclockwise to make the device stand upright. At this time, the left side of the base (1) and the placement plate (91) are in contact with the ground, and the sapling is located between the first clamp (74) and the second clamp (93), and the sapling is in contact with the second clamp (93). At this time, the user can rotate one of the lead screws (72) and use the sprocket one (76) to drive the other side lead screw (72) to rotate forward. When the lead screw (72) rotates forward, it drives the nuts (75) on the left and right sides to approach each other, so that the telescopic connecting rod (73) is unfolded and pushes the first clamp (74) to approach the sapling. When the first clamp (74) is in contact with the sapling, the lead screw (72) is stopped from rotating, so that the first clamp (74) and the second clamp (93) are used to support and fix the sapling; S3. When the device is erected to support the sapling, the user can control the motor (86) through the controller (5) to drive the screw rod (82) to rotate forward. When the screw rod (82) rotates forward, it drives the fixing plate (83) and the cutting rod (812) to descend through the threaded hole (84), so that the cutting rod (812) is inserted into the ground to fix the device body. After the cutting rod (812) is inserted into the soil, the user can rotate the worm (818) and use the worm gear (817) to drive the connecting shaft (815) and the cam (814) to rotate.

The blocking rod (821) is moved so as to be separated from the seepage hole (822) to open the seepage hole (822). Then, the user can rotate the external threaded tube (45) so as to separate the external threaded tube (45) from the internal threaded tube (414), and connect one of the external threaded tubes (87) to the internal threaded tube (414). At this time, the water pump (44) is controlled to work so that the water or nutrient solution in the liquid storage tank (41) is input into the plurality of installation cavities (813) through the internal threaded tube (414), the external threaded tube (87), the connecting hose (88), the shunt tube (810), and the connecting tube (811). Then, the clean water or nutrient solution flows out through the seepage hole (822) and seeps into the soil around the roots of the saplings, thereby directly irrigating the roots of the saplings.
