Description

Technical Field

[0001] This utility model relates to a root protection device, and more particularly to a seedling root protection device. Background Technology

[0002] Protective devices for seedling roots are used during seedling transplantation to reduce damage to the root system. Generally, the soil around the roots of the seedling from its original planting site is transplanted along with the seedling. This results in a root ball of a certain diameter around the seedling roots during transplantation. These roots are usually bound with straw ropes and biodegradable cloth strips. However, the root ball is still easily damaged during long-distance transportation, resulting in a low survival rate for transplanted seedlings.

[0003] Existing root protection devices for seedlings take into account the need to prevent the root ball from being damaged by vibration and bumps during transportation. However, the root cause of vibration and bumps is that there are gaps between the irregular shape of the root ball and the protection device, which cannot effectively fix the root ball elastically. Utility Model Content

[0004] The purpose of this utility model is to provide a seedling root protection device to solve the problem that existing seedling root protection devices cannot effectively and elastically fix the root ball due to the gap between the irregular shape of the root ball and the protection device.

[0005] To address the aforementioned problems, this utility model provides a seedling root protection device, comprising a hemispherical shell, a separate upper cover connected to the hemispherical shell, an array of screw hole plates fixedly connected to the top of the hemispherical shell along its periphery, a lifting eye screw threadedly connected to the screw hole plates, an array of pads fixedly connected to the bottom of the upper cover along its periphery for the lifting eye screw to pass through, a limiting ring provided on the pad for the lifting eye screw, and multiple annular airbags fixedly connected to the inner wall of the hemispherical shell.

[0006] The seedling root protection device provided by this utility model also has the following technical features:

[0007] Furthermore, the hemispherical shell between the annular airbags is provided with an array of permeable holes.

[0008] Furthermore, the annular airbags are fixedly connected by connecting air passages, and the connecting air passages and water-permeable holes are arranged alternately.

[0009] Furthermore, an air valve is fixedly connected to the hemispherical shell, and the air valve is connected to the annular airbag.

[0010] Furthermore, the valve includes a valve tube, an inner fixed plate and an outer fixed plate are fixedly connected inside the valve tube, and an air inlet is provided on both the inner fixed plate and the outer fixed plate. A valve plate that can move elastically is provided between the inner fixed plate and the outer fixed plate. The valve plate abuts against the outer fixed plate, and a valve rod is fixedly connected to the valve plate. The valve rod extends out from the air inlet on the outer fixed plate.

[0011] Furthermore, a spring is fixedly connected between the valve plate and the inner fixed plate.

[0012] Furthermore, the annular airbag is made of a flexible, puncture-resistant material.

[0013] The present invention has the following beneficial effects: The seedling root protection device described in this application uses an annular airbag to fill the gap between the hemispherical shell and the soil ball according to the shape of the soil ball. It plays a role in fixing and shock absorption during the transplanting and transportation of seedlings, effectively fixing the soil ball elastically, ensuring that the seedling roots are not damaged and improving the survival rate of transplanted seedlings.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0019] like Figures 1 to 3 In the embodiment of the seedling root protection device of this utility model shown, the seedling root protection device includes a hemispherical shell 1, a split upper cover 2 connected to the hemispherical shell 1, an array of screw hole plates 3 fixedly connected to the top of the hemispherical shell 1 along the periphery, a lifting eye screw 4 threadedly connected to the screw hole plate 3, an array of pads 5 fixedly connected to the bottom of the upper cover 2 along the periphery for the lifting eye screw 4 to pass through, a limiting ring 6 provided on the pad 5 for the lifting eye screw 4, and a plurality of annular airbags 7 fixedly connected to the inner wall of the hemispherical shell 1.

[0020] Specifically, the bundled soil ball is covered with non-woven fabric, and the hemispherical shell 1 is placed on the bottom of the soil ball. The separate upper cover 2 is then fastened onto the hemispherical shell 1, and the pad 5 and screw hole plate 3 are aligned. The upper cover 2 and the hemispherical shell 1 are connected using eye bolts 4. When the connection is tightened, the annular air bladder 7 is squeezed and deformed to adapt to the irregular shape of the soil ball, gradually filling the gap between the soil ball and the hemispherical shell 1. This provides an elastic fixation effect during transportation, preventing damage to the roots of the seedlings.

[0021] In one embodiment of this application, preferably, the hemispherical shell 1 between the annular airbags 7 is provided with an array of permeable holes 8. The seedlings need to be watered before transplanting. During transportation, excessive moisture should be avoided to prevent poor ventilation of the seedling roots. Water flows out through the permeable holes 8 and air enters through the permeable holes 8 to avoid damage to the root system caused by long-term transportation.

[0022] In one embodiment of this application, preferably, a connecting air passage 9 is fixedly connected between the annular airbags 7, and the connecting air passage 9 and the water-permeable hole 8 are arranged alternately to allow gas to circulate between the annular airbags 7 so as to better adapt to the irregular shape of the soil ball and make the fit with the soil ball tighter.

[0023] In one embodiment of this application, preferably, a gas valve 10 is fixedly connected to the hemispherical shell 1, and the gas valve 10 is in communication with the annular airbag 7 for introducing gas into the annular airbag 7 or releasing gas from the annular airbag 7.

[0024] In one embodiment of this application, preferably, the air valve 10 includes a valve tube 11, an inner fixing plate 12 and an outer fixing plate 13 are fixedly connected inside the valve tube 11, and air inlets (not shown in the figure) are opened on both the inner fixing plate 12 and the outer fixing plate 13. A valve plate 14 is provided between the inner fixing plate 12 and the outer fixing plate 13, and the valve plate 14 abuts against the outer fixing plate 13. A valve stem 15 is fixedly connected to the valve plate 14, and the valve stem 15 extends out from the air inlet on the outer fixing plate 13 to control the gas entering or releasing the annular airbag 7.

[0025] In one embodiment of this application, preferably, a spring 16 is fixedly connected between the valve plate 14 and the inner fixing plate 12 to make the valve plate 14 fit with the outer fixing plate 13 to prevent gas from escaping from the annular airbag 7.

[0026] In one embodiment of this application, preferably, the annular airbag 7 is made of a flexible, puncture-resistant material, so that the annular airbag 7 can better adapt to the shape of the soil ball while avoiding sharp objects from puncturing the annular airbag 7.

[0027] In summary, the seedling root protection device in the above embodiments of this utility model specifically involves placing a hemispherical shell 1 over the soil ball of the seedling to be transported, and fixing the top cover 2 to the hemispherical shell 1 via a lifting eye bolt 4. Air is introduced into the annular air bladder 7 through the air valve 10, and all the annular air bladders 7 are inflated through the connecting air passage 9 to adapt to the irregular shape of the soil ball, so that the soil ball fits snugly against the annular air bladder 7. The water and air required in the soil ball enter and exit through the water permeable hole 8. During transplanting, the gas in the annular air bladder 7 is released through the air valve 10, and the lifting eye bolt 4 is removed to remove the top cover 2 and the hemispherical shell 1. This device utilizes the deformation of the annular air bladder 7 under pressure to adapt to the irregular shape of the soil ball, filling the gap between the soil ball and the hemispherical shell 1. It plays a role in fixing and shock absorption during the transplanting and transportation of seedlings, effectively elastically fixing the soil ball, ensuring that the seedling roots are not damaged, and improving the survival rate of transplanted seedlings.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
