Description

Technical Field

[0001] The present invention relates to the technical field of seedling planting, and in particular to a seedling planting auxiliary protection device. Background Art

[0002] Planting seedlings is an important agricultural and horticultural activity, involving the process of nurturing plants from seeds or cuttings until they can grow independently. Post-plant maintenance is a very demanding task, directly affecting their survival rate and healthy growth. During the dry season, spraying moisturizer on the trunks of seedlings is an effective water conservation measure, reducing water evaporation and maintaining humidity in the trunks. However, existing seedling spraying devices are only capable of spraying moisturizer on seedlings. After spraying, staff or other equipment are required to wrap the trunks with insulation material, which reduces the efficiency of seedling maintenance and is costly.

[0003] Therefore, a seedling planting auxiliary protection device has been developed, which can automatically wrap the insulation material around the tree trunk after spraying the moisturizer, thereby improving the efficiency of seedling maintenance and saving costs. Summary of the Invention

A connecting belt 37 is wound around the inner screw sleeve 38 and the output shaft of the motor 36 through a transmission wheel.

[0036] like Figure 1 、 Figure 5 、 Figure 6 and Figure 7As shown, the spraying mechanism 4 includes a water tank 41, a rotating plate 42, a sprayer 43, a nozzle 44, a staggered valve 45, a compression spring 46, a belt rod 47, a toothed belt 48 and a spur gear 49. The upper side of the lifting frame 31 is connected to the water tank 41, the inner side of the front seat 34 is rotatably connected to the rotating plate 42, the inner side of the rotating plate 42 is connected to the sprayer 43, the right side of the sprayer 43 is connected to five nozzles 44, and the lower right side of the water tank 41 is slidably connected to the staggered Valve 45, a compression spring 46 is connected between the offset valve 45 and the water tank 41, the offset valve 45 is in contact with the sprayer 43, the front seat 34 and the front and rear parts are rotatably connected with a belt rod 47, a toothed belt 48 is wound around the belt rod 47 through a transmission gear, a transmission gear is provided at the lower part of the output shaft of the motor 36, the toothed belt 48 is engaged with the transmission gear, the middle part of the belt rod 47 is connected with a spur gear 49, and the spur gears 49 are all engaged with the rotating plate 42.

[0037] like Figure 1 、 Figure 8 and Figure 9 As shown, the wrapping mechanism 5 includes a storage bin 51, an arc-shaped rack 52, a convex gear 53, a strap 54 and a cutter 55. The lower side of the arc-shaped seat 35 is rotatably connected to the storage bin 51, the upper part of the storage bin 51 is connected to the arc-shaped rack 52, the lower side of the belt rod 47 is connected to the convex gear 53, and the convex gears 53 are engaged with the arc-shaped rack 52. A strap 54 is wrapped around the inside of the storage bin 51, and the strap 54 is a heat-insulating material. The cutter 55 is slidably connected to the right side of the front of the storage bin 51.

[0038] When using the present invention, first grasp the handle 2 to push the cart 1 to the seedling planting position, so that the front seat 34 surrounds the outside of the seedling trunk, and then start the motor 36, and drive the inner screw sleeve 38 to rotate through the connecting belt 37, so that the inner screw sleeve 38 drives the lifting seat 31 to move upward on the screw rod 33, and the guide plate 32 guides the lifting seat 31. At the same time as the motor 36 is started, the transmission gear and the toothed belt 48 are engaged and moved, so that the toothed belt 48 rotates and drives the belt rod 47 to rotate, so that the spur gear 49 is engaged and moved with the rotating plate 42, so that the rotating plate 42 rotates around the front seat 34. As the trunk of the seedling rotates and the rotating plate 42 rotates, the sprayer 43 is driven to rotate. When the sprayer 43 rotates to the water tank 41, the offset valve 45 is pushed to move, and the compression spring 46 is stretched to open the water tank 41, so that the moisturizing agent in the water tank 41 flows into the sprayer 43, and the sprayer 43 is started, so that the nozzle 44 sprays the moisturizing agent evenly onto the trunk of the seedling. When the sprayer 43 continues to move and disengages from the offset valve 45, the compression spring 46 rebounds, so that the offset valve 45 is reset to close the water tank 41, thereby automatically spraying the moisturizing agent on the trunk of the seedling and improving the efficiency of seedling maintenance. When spraying moisturizing agent on the trunk of the seedling, one end of the strap 54 is fixed to the bottom of the trunk of the seedling. When the belt rod 47 rotates, the convex gear 53 is driven to rotate, so that the convex gear 53 engages with the arc rack 52, and the storage bin 51 rotates on the arc seat 35 and rotates around the trunk, so that the strap 54 moves upward with the arc seat 35 and gradually wraps around the position after the moisturizing agent is sprayed on the trunk. When the wrapping is completed, the cutter 55 is pushed to move and cut the strap 54, thereby automatically wrapping the insulation material on the trunk after the moisturizing agent is sprayed, improving the efficiency of seedling maintenance and saving costs.

[0039] like Figure 1 、 Figure 10 and Figure 11 As shown, a vibration mechanism 6 is also included, which includes a knocking plate 61, a limiting column 62, a torsion spring 63 and a toggle tooth 64. Seven knocking plates 61 are rotatably connected to the lower part of the front seat 34, and seven limiting columns 62 are connected to the lower part of the front seat 34. The knocking plates 61 are all in contact with and cooperate with adjacent limiting columns 62. A torsion spring 63 is connected between the knocking plates 61 and the front seat 34. A plurality of toggle teeth 64 are connected to the lower part of the rotating plate 42, and the toggle teeth 64 are squeezed and fitted with the knocking plates 61.

[0040] The vibration mechanism 6 of the present device can be used to knock on the trunks of seedlings. When the rotating plate 42 rotates, the toggle tooth 64 is driven to rotate, so that the toggle tooth 64 drives the knocking plate 61 to rotate, and the torsion spring 63 is deformed. At this time, the knocking plate 61 is away from the trunk. When the toggle tooth 64 is separated from the knocking plate 61, the torsion spring 63 recovers, so that the knocking plate 61 is reset to hit the trunk, thereby being able to knock on the trunks of seedlings to facilitate checking the health of the trunks. The limiting column 62 is used to limit the rotation angle of the knocking plate 61.

[0041] like Figure 1 and Figure 12 As shown, a heating mechanism 7 is also included, which includes a heater 71 and a heating pipe 72. Two left and right heaters 71 are connected to the front and back sides of the water tank 41, and three heating pipes 72 are connected between the heaters 71 on the same side.

[0042] The heating mechanism 7 of the device can be used to heat the moisturizer. When the weather is cold, the heater 71 is started to make the heating tube 72 heat the water tank 41, thereby heating the moisturizer and preventing the moisturizer from solidifying or thickening.

[0043] like Figure 1 and Figure 12 As shown, it also includes an expansion mechanism 8, which includes an alignment plate 81 and a guide plate 82. The right sides of the front and rear parts of the front seat 34 are connected to the alignment plate 81 through four flexible rods, and the right sides of the alignment plate 81 are connected to the guide plate 82. The guide plates 82 are all folded to facilitate the introduction of seedling trunks.
