[0002] Seedlings are tree seedlings with root systems and trunks. All seedlings cultivated in a nursery, regardless of their age, are called seedlings before they are planted. There are three types of seedlings: seedlings, vegetative propagation seedlings, transplanted seedlings, and bed seedlings.

[0003] When afforestation is carried out for forestry projects, it is necessary to protect the cultivated seedlings to prevent them from being damaged by insects or weather. The measures for protecting seedlings in the prior art usually require building a protective shed on site. The construction process is labor-intensive and the construction materials are not easy to carry, thus affecting the progress of the afforestation project. Some integrated protective covers, such as the "a mobile seedling protection cover for afforestation in forestry projects" proposed in patent application number "CN202322442929.7", have a low range of protection for seedlings. A single protective cover cannot protect multiple seedlings and needs to be set on the seedlings one by one. A large number of seedlings need to be planted when afforestation is carried out for forestry projects. The cost of the above patent when used for a large number of seedlings is high and the installation efficiency is low. Utility Model Content

[0004] The utility model aims to make up for the deficiencies of the prior art and provides a mobile seedling protection cover for afforestation in forestry engineering.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a mobile seedling protection cover for forestry engineering afforestation, including a plurality of groups of mobile brackets, and also including:

[0006] A retractable protective cover, which is arranged on a mobile support and is used to protect a large number of seedlings;

[0007] A moving component, which is arranged on one side of the moving bracket and is used to control the protection range of the protective cover;

[0008] The retractable protective cover comprises a retractable bracket, which is arranged between two adjacent groups of movable brackets, a layer of transparent plastic cloth is arranged between the two adjacent groups of movable brackets, and the inner walls of the two outermost groups of movable brackets are provided with door curtains;

[0009] Among them, the moving component includes a fixing part, which is installed on one side of the moving bracket, a fixed shaft is installed inside the fixing part, a gear is installed on the end of the fixed shaft, a rotating part is rotatably connected to the outer surface of the fixed shaft, a roller is arranged at the bottom of the rotating part, a second slot is opened inside the rotating part, a fixing rod is installed inside the second slot, and a return spring and a limit part are sleeved on the outer surface of the fixing rod.

[0010] As mentioned above, the telescopic bracket includes two sets of fixed brackets, the fixed bracket is installed on one side of the movable bracket, the fixed bracket is hinged with a rotating bracket inside, the rotating bracket is provided with a first notch inside, and the first notch is slidably matched with a slide rod inside.

[0011] As mentioned above, the return spring is elastically supported between the second notch and the limiting member.

[0012] As mentioned above, the top of the limiting member is tooth-shaped, and the limiting member is meshedly connected with the gear.

[0013] As mentioned above, a row of long spikes is installed on one side of the rotating member, and the long spikes can be inserted into the ground when the rotating member rotates upward along the outer surface of the fixed shaft.

[0014] As mentioned above, the sliding rod passes through the first notch and is arranged between the two sets of rotating frames.

[0015] Compared with the prior art, the mobile forestry engineering afforestation seedling protection cover has the following beneficial effects:

[0016] 1. The utility model drives the mobile bracket on one side to move by the roller, so that the adjacent mobile bracket can be driven to move and the transparent plastic sheet can be unfolded through the transparent plastic sheet.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-5 As shown, the utility model provides a mobile seedling protection cover for forestry engineering afforestation, including a plurality of groups of mobile brackets 1, and also includes:

[0027] A retractable protective cover, which is arranged on the mobile support 1 and is used to protect a large number of seedlings;

[0028] A moving component, which is arranged on one side of the moving bracket 1 and is used to control the protection range of the protective cover;

[0029] The retractable protective cover includes a retractable bracket 2, which is arranged between two adjacent groups of mobile brackets 1. A layer of transparent plastic cloth 3 is arranged between the two adjacent groups of mobile brackets 1, and a door curtain 14 is arranged on the inner wall of the two outermost groups of mobile brackets 1.

[0030] Among them, the moving component includes a fixing part 4, which is installed on one side of the moving bracket 1. A fixed shaft 5 is installed inside the fixing part 4, a gear 6 is installed at the end of the fixed shaft 5, the outer surface of the fixed shaft 5 is rotatably connected to a rotating part 7, a roller 8 is arranged at the bottom of the rotating part 7, a second slot 9 is opened inside the rotating part 7, a fixing rod 10 is installed inside the second slot 9, and a reset spring 11 and a limit part 12 are sleeved on the outer surface of the fixing rod 10.

[0031] The roller 8 drives the mobile bracket 1 on one side to move, so that the adjacent mobile bracket 1 can be pulled to move through the transparent plastic sheet 3. At the same time, through the cooperation between the fixed frame 21 and the rotating frame 22, when the mobile bracket 1 moves, the rotating frame 22 will be driven to rotate along the inside of the fixed frame 21. As the mobile bracket 1 moves, the distance between the two adjacent groups of fixed frames 21 will increase. At this time, the sliding bar 24 will slide along the inner wall of the first notch 23. When it moves to a certain distance, it will be limited to limit the distance between the two groups of mobile brackets 1. This can avoid excessive pulling force on the mobile bracket 1 causing the transparent plastic sheet 3 to tear, and at the same time, it can prevent position deviation from occurring when the mobile bracket 1 moves, so that it keeps moving in a straight line.

[0032] like Figure 2 , 5 As shown, the telescopic bracket 2 includes two sets of fixed brackets 21, the fixed bracket 21 is installed on one side of the mobile bracket 1, the fixed bracket 21 is hinged with a rotating bracket 22 inside, the rotating bracket 22 is provided with a first notch 23 inside, and the first notch 23 is slidably matched with a slide rod 24 inside.

[0033] Through the design of the two sets of fixed frames 21, when the distance between the mobile brackets 1 is expanded, the two sets of rotating frames 22 will rotate simultaneously and extend the distance between the two sets of rotating frames 22 through the cooperation between the sliding rod 24 and the first notch 23, so that the mobile bracket 1 is more stable when contracted or extended.

[0034] like Figure 3 As shown, the return spring 11 is elastically supported between the second notch 9 and the limiting member 12 .

[0035] Through the design of the return spring 11, the limiter 12 has good elastic return performance. At this time, since the return spring 11 is in a compressed state, an elastic force is applied to the limiter 12, so that the fit between the limiter 12 and the gear 6 is tighter.

[0036] like Figure 3 As shown, the top of the limiting member 12 is tooth-shaped, and the limiting member 12 is meshedly connected with the gear 6 .

[0037] Through the cooperation between the limiting member 12 and the fixing rod 10 , the limiting member 12 can move along the outer surface of the fixing rod 10 , and through the cooperation between the limiting member 12 and the gear 6 , the rotating member 7 can be limited.

[0038] like Figure 3 As shown, a row of long spikes 13 are installed on one side of the rotating member 7 , and the long spikes 13 can be inserted into the ground when the rotating member 7 rotates upward along the outer surface of the fixed shaft 5 .

[0039] Through the design of the spike 13, when the limit of the rotating member 7 is released, the rotation of the rotating member 7 can drive the spike 13 to rotate, so that the spike 13 remains vertical to the ground, thereby facilitating the control of the spike 13 being inserted into the ground and making the mobile bracket 1 more stable.

[0040] like Figure 5 As shown, the slide bar 24 passes through the first slot 23 and is disposed between the two sets of rotating frames 22 .

[0041] The design of the slide bar 24 allows the two groups of rotating frames 22 to be retractable. When one group of rotating frames 22 rotates, the other group of rotating frames 22 can rotate synchronously, which is convenient for extending or storing the mobile bracket 1.

[0042] Working principle:

[0043] First, one of the staff members is required to hold the mobile bracket 1 on one side, and the other staff member pulls the mobile bracket 1 on the other side and lifts the door curtain 14. At this time, the roller 8 makes the movement of the mobile bracket 1 easier. At the same time, the transparent plastic sheet 3 will pull the adjacent mobile bracket 1 to move and unfold the transparent plastic sheet 3, so that it can protect a large range of seedlings. Then the staff can pull the limit piece 12 to separate from the gear 6. At this time, the long spike 13 is driven to rotate through the cooperation between the rotating part 7 and the fixed shaft 5. When the long spike 13 is kept vertical to the ground, the limit piece 12 is released. Due to the elastic force of the reset spring 11, the limit piece 12 will be driven to mesh with the gear 6 and limit the rotating part 7. The staff can step on the mobile bracket 1 to insert the long spike 13 into the ground, making the mobile bracket 1 more stable.
