Description

Technical Field

[0001] The invention relates to the technical field of seedling transplanting, and in particular to a protective device used for forestry seedling transplanting. Background Art

[0002] Sapling transplanting is a common seedling planting method in the field of agriculture and forestry. During the process of sapling transplanting, the saplings to be transplanted need to be transported to the location where they need to be transplanted together with the soil at their roots. The soil at the roots of the saplings is easily squeezed or shaken and falls off during transportation, thus affecting the survival rate of the saplings. Therefore, some protective measures need to be taken for the saplings and the soil at their roots.

[0003] At present, plastic film is usually used to wrap the soil at the roots of seedlings during transplanting and protection. This can prevent the soil from dispersing during transplanting and transportation, and play a certain protective role. However, since plastic film is used, it is relatively fragile and easy to break during transportation bumps, causing the soil at the roots of the seedlings to disperse. During the transportation of seedlings, the seedlings are usually dumped in the transport vehicle. When the vehicle stops suddenly, the seedlings at the back may collide with the soil of the seedlings in front, which may easily cause the trunks of the seedlings to break. Summary of the invention

[0004] In order to overcome the disadvantage that plastic film is used to wrap the transplanted saplings for protection, but the plastic film is relatively fragile and easily broken during transportation bumps, causing the soil at the roots of the saplings to be scattered, the present invention provides a protective device for forestry sapling transplanting that has good sapling protection effect and can be stacked.

DETAILED DESCRIPTION

[0038] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Embodiment: A protective device for transplanting forestry seedlings, such as Figure 1-Figure 5As shown, it includes a placement box 1, a placement frame 2, a box cover 3, an extrusion block 31, a limiting mechanism 4 and a pushing mechanism 5. A plurality of placement frames 2 are fixedly connected in the placement box 1. The lower end of the placement frame 2 passes through the bottom of the placement box 1. There are three rows of placement frames 2, six in each row. The placement frame 2 is barrel-shaped. The upper side of the placement box 1 is provided with a box cover 3, as shown in FIG. Figure 7 As shown, extrusion blocks 31 are fixedly connected to the left and right sides of the top of the box cover 3, and a limiting mechanism 4 for limiting the saplings in the placing frame 2 is provided on the placing frame 2. A pushing mechanism 5 for starting the limiting mechanism 4 when the placing boxes 1 are stacked is provided between the limiting mechanism 4 and the placing box 1. It should be supplemented that multiple rows of air holes are evenly opened on the left and right sides of the placing box 1, the bottom of the supporting feet of the placing box 1 is consistent with the groove on the extrusion block 31, and the front and back sides of the placing box 1 are opened with strip holes for lifting.

[0040] like Figure 6-Figure 9 As shown, the limiting mechanism 4 includes a moving ring 41, a first moving plate 42, a connecting rod 43, a clamping plate 44 and a limiting plate 45. The outer side of the placement frame 2 is slidably connected to the moving ring 41, and eight first moving plates 42 are fixedly connected to the moving ring 41. The first moving plates 42 are combined in pairs, and a connecting rod 43 is fixedly connected between two adjacent first moving plates 42. The upward movement of the first moving plate 42 can drive the connecting rod 43 to move upward. The upper end of the placement frame 2 is rotatably connected to the limiting plate 45, and the outer sides of the limiting plates 45 are fixedly connected to the clamping plates 44. The connecting rod 43 and the clamping plate The plate 44 is slidably connected, and a sliding hole is provided on the snap-in plate 44. The connecting rod 43 is located in the sliding hole. The snap-in plate 44 is located between the two first movable plates 42. The connecting rod 43 moves upward to drive the snap-in plate 44 and the limit plate 45 to rotate into the placement frame 2; the pushing mechanism 5 includes a first sliding rod 51 and a push plate 52. The push plate 52 is fixedly connected to the bottom of the movable ring 41, and the first sliding rod 51 is fixedly connected to the bottom of the push plate 52. The lower end of the first sliding rod 51 passes through the bottom of the placement box 1 and is slidably connected to the placement box 1. The same push plate 52 can be fixedly connected to multiple movable rings 41.

[0041] When people use the device to transport saplings, they first open the box cover 3, put the saplings and the soil at their roots in the placement frame 2, and then cover the box cover 3. After multiple devices are filled with saplings, the box cover 3 of the uppermost device is removed and placed on the bottom of the lowermost device, and multiple devices are stacked and placed in the transport vehicle; when multiple devices are stacked, the first sliding rod 51 of the upper device will be squeezed by the squeezing block 31 on the box cover 3 of the lower device, so that the first sliding rod 51 of the upper device moves upward, thereby driving the push plate 52, the moving ring 41 and the first moving plate 42 to move upward, and the first moving plate 42 moves upward so that the clamping plate 44 and the limiting plate 45 rotate inward, and the limiting plate 45 buckles on the soil at the root of the sapling to fix the sapling in the placement frame 2; when the upper device is removed from the lower device, the first sliding rod 51 of the upper device is no longer squeezed by the squeezing block 31 on the box cover 3 of the lower device. Due to the effect of gravity, the first sliding rod 51 of the upper device moves downward, thereby driving the push plate 52, the moving ring 41 and the first moving plate 42 to move downward, so that the clamping plate 44 and the limiting plate 45 rotate outward, no longer fixing the sapling, and the sapling can be taken out of the placement frame 2 for transplanting.

[0042] like Figure 1 , Fig.10 , Fig.11 and Fig.12 As shown, it also includes an adaptation mechanism 6. The placement frame 2 is provided with an adaptation mechanism 6, which is used to adjust the position of the sapling in the placement frame 2 according to the weight of the sapling. The adaptation mechanism 6 includes a second movable plate 61, an elastic member 62 and a second sliding rod 63. The placement frame 2 is slidably connected with the second movable plate 61, and a small hole is opened on the second movable plate 61. When the staff accidentally sprays too much water on the sapling, the excess water can flow out from the small holes on the second movable plate 61. The second movable plate 61 contacts the bottom of the sapling placed in the placement frame 2, and the second sliding rod 63 is fixedly connected to the bottom of the second movable plate 61. The second sliding rod 63 is used to guide the second movable plate 61. The lower end of the second sliding rod 63 passes through the bottom of the placement frame 2 and is slidably connected to the placement frame 2. The second sliding rod 63 is wound with an elastic member 62, and the elastic member 62 is located between the bottom of the placement frame 2 and the bottom of the second movable plate 61. It should be supplemented that the elastic member 62 is a spring.

[0043] When the sapling is placed in the placement frame 2, the second movable plate 61 slides downward under the pressure of the sapling, and the elastic member 62 is compressed. When the elastic force of the elastic member 62 on the second movable plate 61 is balanced with the pressure of the sapling, the second movable plate 61 will stop sliding downward. Since the amount of soil wrapped around the roots of each sapling is different, the larger the amount of soil wrapped around the roots of the sapling, the greater the pressure of the sapling on the second movable plate 61. The second movable plate 61 will slide downward for a longer distance. The larger the amount of soil wrapped around the roots of the sapling, the higher the height of the soil wrapped around the roots of the sapling. The distance between the second movable plate 61 and the limiting plate 45 can be increased according to the increase in the amount of soil wrapped around the roots of the sapling. Therefore, the adaptability mechanism 6 can adjust the position of the sapling according to the different amounts of soil wrapped around the roots of each sapling. Since the position height of the limiting plate 45 is fixed, adjusting the position of the sapling is equivalent to adjusting the position of the limiting plate 45 relative to the sapling, thereby achieving a better effect of fixing each sapling. When the sapling is taken out of the placement frame 2, the second movable plate 61 is driven to move upward back to the initial position due to the reset effect of the elastic member 62.

[0044] like Figure 1 , Fig.13 , Fig.14 , Fig.15 and Fig.16 As shown, it also includes a spraying mechanism 7, a spraying mechanism 7 is provided on the box cover 3, and the spraying mechanism 7 is used to spray water on the seedlings. The spraying mechanism 7 includes a water inlet box 71, a water outlet box 72, a water inlet pipe 73, a third movable plate 74, a reset spring 741, a first connecting pipe 75, a second connecting pipe 76, a spraying pipe 77 and a water outlet pipe 78. The front side of the box cover 3 is fixedly connected to the water inlet box 71, the rear side of the box cover 3 is fixedly connected to the water outlet box 72, the front side of the water inlet box 71 is connected to the water inlet pipe 73, the water inlet box 71 is slidably connected to the third movable plate 74, the third movable plate 74 and the front wall of the water inlet box 71 are connected to the reset spring 741, the right part of the third movable plate 74 is provided with a small hole, and the third movable plate 74 is connected to the third movable plate 74. Two connecting pipes 76, a first connecting pipe 75 is connected to the front side of the water inlet box 71, the front end of the first connecting pipe 75 is slidably connected to the second connecting pipe 76, the first connecting pipe 75 is located on the left side of the water inlet pipe 73, and the second connecting pipe 76 is located in the first connecting pipe 75 in the initial state, and the rear end of the first connecting pipe 75 is connected to the water outlet box 72, and the rear side of the water outlet box 72 is connected to the water outlet pipe 78, three holes are opened on the front side of the box cover 3, and the positions of the holes on the front side of the box cover 3 are different from the small holes on the third movable plate 74, three spray pipes 77 are fixedly connected in the box cover 3, and the spray pipes 77 are connected to the water inlet box 71 through the holes on the front side of the box cover 3 respectively, and six spray holes are opened on the lower side of each spray pipe 77, and the spray holes correspond to the placement frame 2.

[0045] When it is necessary to spray water on the seedlings, the water inlet pipe 73 of the device on the same layer and the same row is connected to the water outlet pipe 78 of the front device. The water inlet pipe 73 of the frontmost device is connected to the water source, and water enters the water inlet tank 71 through the water inlet pipe 73. Initially, the first connecting pipe 75 is located outside the second connecting pipe 76 and is not connected to the water inlet tank 71. Water flows into the spray pipe 77 through the small holes on the third movable plate 74. The water enters the spray pipe 77 and is sprayed onto the seedlings along the spray holes on the lower side of the spray pipe 77. Since the water inflow on the front side of the third movable plate 74 in the water inlet tank 71 is greater than the water outflow on the rear side of the third movable plate 74 in the water inlet tank 71, the third movable plate 74 moves backward, driving the second connecting pipe 76 to move backward, and the reset spring 741 is stretched. When the third movable plate 74 moves to contact the rear wall of the water inlet tank 71, the small holes on the spray pipe 77 and the third movable plate 74 are blocked, and the first connecting pipe 75 is separated from the second connecting pipe 76. A connecting pipe 75 is connected to the water inlet box 71, and all the water will flow from the first connecting pipe 75 into the water outlet box 72, and then flow out from the water outlet pipe 78. When the water outlet pipe 78 is connected to the water inlet pipe 73 of another device, water flows from the water inlet pipe 73 of the other device into the water inlet box 71 of the device, and the above steps are repeated. Finally, water flows out from the water outlet pipe 78 of another device. When water flows out from the water outlet pipe 78 of the last device in the same layer and row, the saplings in the devices in the same layer and row are all sprayed with water, and the water source can be connected to the devices in another layer and another row; when the water source is removed from the water inlet pipe 73 of the frontmost device, the third movable plate 74 is no longer impacted by the water flow, and the reset action of the reset spring 741 drives the third movable plate 74 to move forward back to the initial position; when supplementation is needed, since the box cover 3 of the uppermost device is placed at the bottom of the lowermost device, the saplings in the uppermost device can be manually sprayed with water.

[0046] When the device is transported to the transplanting site, there may be soil bulges on the transplanting ground, so that the limiting mechanism 4 cannot be reset due to gravity. At this time, it is inconvenient to take out the seedlings from the placement frame 2. In order to solve this problem, Fig. 9 , Fig.17 and Fig.18 As shown, a positioning mechanism 8 is also included. A positioning mechanism 8 is provided at the bottom of the placement box 1. The positioning mechanism 8 is used to clamp the pushing mechanism 5. The positioning mechanism 8 includes a clamping plate 81 and a fixing rod 82. Four fixing rods 82 are fixedly connected to the bottom of the placement box 1. The four fixing rods 82 are symmetrically distributed front and back in pairs. A clamping plate 81 is slidably connected between two fixing rods 82. A clamping hole is opened on the clamping plate 81. A clamping groove 83 is opened on the first sliding rod 51. The first sliding rod 51 is located in the clamping hole on the clamping plate 81. The clamping plate 81 moves outward and is embedded in the clamping groove 83 on the first sliding rod 51. The clamping plate 81 is opened with a hole for pulling the clamping plate 81 outward.

[0047] First, lift the device or place it on a flat ground. At this time, the limiting mechanism 4 loses the squeezing of the squeezing block 31 and is in the initial state. Then, pull the card plates 81 on both sides outward so that the card plates 81 are stuck in the card slots 83 on the first sliding rod 51 to position the first sliding rod 51. At this time, when the device is placed on the ground and transplanted again, the raised soil pile on the transplanting ground will not squeeze the first sliding rod 51 and will not cause the first sliding rod 51 to move upward. The limiting mechanism 4 will not limit the saplings. At this time, take out the saplings from the placement frame 2, and the soil at the roots of the saplings will not be stuck. After all the saplings are taken out, push the card plates 81 on both sides inward. At this time, the limiting mechanism 4 can be used normally again.

[0048] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
