[0002] Saline-alkali land improvement refers to the transformation and utilization of saline soil, alkaline soil and saline-alkali land to improve the productivity and ecological functions of the land. The purpose of improvement is to solve the problem of soil salinization and improve the physical and chemical properties of the soil. Field seedling transport vehicles play an important role in saline-alkali land improvement. They are usually used to transport seedlings and fertilizers. To sum up, the problems existing in the prior art are as follows: A field seedling transport vehicle is a mechanical device used for transporting seedlings or young plants in agricultural production. It can greatly reduce the labor intensity of manual work, improve the transport efficiency, and at the same time reduce the damage to the farmland structure. Since the young plants are relatively fragile, they need to be placed on a seedling rack, and then the seedling rack is placed in the truck bed for transportation. After the seedling rack is placed, its position is not fixed. However, the terrain in the field is relatively potholed, and the seedling rack is easily toppled due to bumps, resulting in the phenomenon that the young plants fall off or even are hit by the seedling rack. However, the existing field seedling transport vehicles used for saline-alkali land improvement do not have components for more stable transportation. Therefore, a field seedling transport vehicle for saline-alkali land improvement is specifically proposed to solve the above problems. Content of the Utility Model

Since the young plants are relatively fragile, they need to be placed on a seedling rack, and then the seedling rack is placed in the truck bed for transportation. After the seedling rack is placed, its position is not fixed. However, the terrain in the field is relatively potholed, and the seedling rack is easily toppled due to bumps, resulting in the phenomenon that the young plants fall off or even are hit by the seedling rack.

[0006] Preferably, an extrusion column is fixedly connected to the rear side of the limiting block, and an extrusion plate for cooperating with the extrusion column is fixedly connected to the front side of the control rod. The surface of the extrusion plate is in contact with the surface of the extrusion column. By providing the extrusion column and the extrusion plate, when the extrusion plate moves, it can generate an extrusion force on the extrusion column, and the two extrusion columns subjected to the extrusion force will move towards each other.

It can greatly reduce the manual labor intensity, improve the transport efficiency, and at the same time reduce the damage to the farmland structure. Since the young seedlings are relatively fragile, they need to be placed on a seedling rack and then the seedling rack is placed in the truck bed for transportation. After the seedling rack is placed, its position is not fixed. However, the terrain in the field is relatively potholed, and the seedling rack is prone to tipping due to jolting, resulting in the phenomenon that the young seedlings fall or are even hit by the seedling rack. However, the existing field seedling transport vehicle for saline-alkali land improvement does not have components for more stable transportation.

[0012] 2. By setting a limiting device in the present utility model, when two extrusion columns are subjected to extrusion force, they will move towards the side close to each other. When the extrusion columns move, they will drive two limiting blocks to move towards the side close to each other along the inner cavity of the stabilizing shell. When the limiting blocks move, the force generated causes the spring to undergo elastic deformation. The restoring force generated when the spring resumes its shape will drive the limiting blocks to snap into the inner cavity of the limiting groove. The limiting device has a limiting effect on the position of the guardrail. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To further understand the content, features, and effects of the present utility model, the following embodiments are cited and described in detail in conjunction with the accompanying drawings.

[0020] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 5 shown, a seedling transport vehicle for saline-alkali land improvement provided by an embodiment of the present utility model includes a vehicle body 1 of the seedling transport vehicle and a carriage 2. The top of the vehicle body 1 of the seedling transport vehicle is fixedly connected to the bottom of the carriage 2. A plurality of seedling racks 3 are movably connected to the inner cavity of the carriage 2. A device housing 4 is fixedly connected to the rear side of the vehicle body 1 of the seedling transport vehicle. A guardrail 5 is movably connected to the top of the device housing 4. A control rod 6 is movably connected to the inner cavity of the device housing 4. The rear side of the control rod 6 penetrates through the device housing 4 and extends to the outside of the inner cavity of the device housing 4. A limiting device 7 is provided inside the device housing 4.

[0022] Referring Figure 5 to

[0023] the above scheme, by providing the limiting device 7, when the guardrail 5 rotates to a suitable position, the limiting device 7 has a limiting effect on the position of the guardrail 5.

[0024] Referring Figure 5 to

[0025] the above scheme, by providing the extrusion column 8 and the extrusion plate 9, when the extrusion plate 9 moves, it can generate an extrusion force on the extrusion column 8. The two extrusion columns 8 subjected to the extrusion force will move towards the side close to each other. When the extrusion column 8 moves, it can drive the limiting block 701 to move.

[0026] Referring Figure 5 to

[0027] the above scheme, by providing the rotating rod 10 and the rotating groove 11, when the guardrail 5 rotates, it can drive the rotating rod 10 to rotate along the inner cavity of the rotating groove 11. The cooperation of the rotating rod 10 and the rotating groove 11 has a limiting effect on the rotating position of the guardrail 5.

[0028] Referring Figure 4, a limiting groove 12 for cooperating with the limiting block 701 is formed on the surface of the rotating rod 10, and the surface of the limiting block 701 is in contact with the inner cavity of the limiting groove 12.

[0029] With the above scheme: by providing the limiting groove 12, when the rotating rod 10 rotates to a proper position and the control rod 6 is released, the restoring force generated by the spring 703 restoring its shape will drive the limiting block 701 to snap into the inner cavity of the limiting groove 12, and the cooperation between the limiting block 701 and the limiting groove 12 has a limiting effect on the position of the rotating rod 10.

[0030] Reference Figure 5 , a moving rod 13 for cooperating with the control rod 6 is fixedly connected to the inner cavity of the device housing 4, and the surface of the moving rod 13 is movably connected to the inner cavity of the control rod 6.

[0031] With the above scheme: by providing the moving rod 13, pulling the control rod 6 drives the control rod 6 to move along the surface of the moving rod 13, and the setting of the moving rod 13 has a limiting effect on the moving position of the control rod 6.

[0032] Reference Figure 2 , a sliding housing 14 is fixedly connected to the inner cavity of the carriage 2, and sliding blocks 15 for cooperating with the sliding housing 14 are fixedly connected to both the left and right sides of the seedling frame 3, and the surface of the sliding block 15 is movably connected to the inner cavity of the sliding housing 14.

[0033] With the above scheme: by providing the sliding block 15 and the sliding housing 14, when the seedling frame 3 moves, it will drive the sliding block 15 to move along the inner cavity of the sliding housing 14, and the cooperation between the sliding block 15 and the sliding housing 14 has a limiting effect on the moving position of the seedling frame 3.

[0034] During use, when the field seedling transport vehicle used for saline-alkali land improvement needs to be transported more stably, the operator first places the transported materials on the seedling rack 3, and then moves the slider 15 into the inner cavity of the sliding shell 14. When the slider 15 moves, it will drive the seedling rack 3 to move into the inner cavity of the truck bed 2. After several seedling racks 3 are placed in the inner cavity of the truck bed 2, the control rod 6 is moved toward the top, driving the control rod 6 to move upward along the surface of the moving rod 13. When the control rod 6 moves, it will drive the extrusion plate 9 to move along the surface of the extrusion column 8. The two extrusion columns 8 subjected to the extrusion force will move toward each other. When the extrusion column 8 moves, it will drive the two limit blocks 701 to move toward each other along the inner cavity of the stabilizing shell 702. When the limit block 701 moves, the force generated causes the spring 703 to undergo elastic deformation. When the limit block 701 disengages from the limit groove 12 and moves completely to the inner cavity of the device shell 4, the guardrail 5 is rotated toward the side close to the truck bed 2. When the guardrail 5 rotates, it will drive the rotating rod 10 to rotate along the inner cavity of the rotating groove 11. When the front side of the guardrail 5 contacts the rear side of the truck bed 2, the control rod 6 is released. The restoring force generated by the spring 703 restoring its shape will drive the limit block 701 to be stuck into the inner cavity of the limit groove 12. The coordinated use of the limit block 701 and the limit groove 12 has a limiting effect on the position of the guardrail 5. The setting of the guardrail 5 has a limiting effect on the position of the seedling rack 3. At this time, the field seedling transport vehicle used for saline-alkali land improvement can be transported more stably.

[0035] To sum up: the field seedling transport vehicle for improving saline-alkali land, by setting a limit device 7, a limit block 701, a stabilizing shell 702 and a limit groove 12 spring 703, solves the problem that the existing field seedling transport vehicle is a mechanical device for transporting seedlings or young seedlings in agricultural production. It can greatly reduce the intensity of manual labor, improve transportation efficiency, and reduce damage to the farmland structure. Since the seedlings are relatively fragile, they need to be placed on the seedling rack, and then the seedling rack is placed in the vehicle bucket for transportation. The seedling rack is not fixed in position after being placed. However, the terrain of the field is relatively bumpy, and the seedling rack is easy to tip over due to bumps, causing the seedlings to fall or even be hit by the seedling rack. However, the existing field seedling transport vehicle used for improving saline-alkali land does not have a component for more stable transportation.
