[0002] Turf laying refers to the greening engineering technology of transplanting pre-cultivated live turf rolls to a target site through artificial means. It is a key step in landscaping, sports field or courtyard beautification, involving soil treatment, grass species selection, laying technology and post-maintenance. It is suitable for places that need immediate greening, such as sports fields and parks. By directly laying pre-cultivated turf rolls, the desired landscape effect can be achieved quickly.

[0003] Currently, most lawn laying is done manually, which involves transporting individual pieces of turf to the desired location, compacting the turf with tools after laying, and then watering the compacted turf. This process involves many steps, is inconvenient, and results in low laying efficiency.

[0004] Therefore, in view of the fact that the above-mentioned manual laying steps are cumbersome, not only inefficient but also wasteful of labor costs, the laying, compaction and watering steps are combined. During the movement of the device, the turf is guided and laid, and then the device's own weight is used to compact the turf. After compaction, the turf is watered to ensure the normal growth of the lawn. Utility Model Content

The moving wheels 4 are symmetrically distributed on the support base plate 1. The guide roller 5 is rotatably connected to the support base plate 1. The rolling roller 7 is rotatably connected to the rolling frame 6. The traction head 2 facilitates the connection and fixation of the device and the power device. During the laying process, the guide roller 5 provides guidance for the unrolling and laying of the lawn. During the movement, the rolling roller 7 can flatten the laid lawn, so that the lawn can fully contact the ground.

[0025] A water storage tank 101 is fixedly connected to the top surface of the supporting base plate 1. The water storage tank 101 is closely attached to the side of the fixed bracket 3. A water inlet pipe 102 is provided on the top surface of one end of the water storage tank 101, and the water inlet pipe 102 is connected to the water storage tank 101. A water pump 103 is fixedly connected to the top surface of the other end of the water storage tank 101. Water is added to the water storage tank 101 through the water inlet pipe 102, and the water stored in the water storage tank 101 is pumped out by the water pump 103 to facilitate the transportation of water.

[0026] A transport pipe 104 is fixedly connected to the outlet end of the water pump 103, and a diversion pipe 105 is fixedly connected to the bottom surface of the supporting base plate 1. The end of the transport pipe 104 is connected to the side of the diversion pipe 105. A nozzle 106 is provided on the bottom surface of the diversion pipe 105. The nozzles 106 are evenly distributed on the diversion pipe 105. Water is transported to the diversion pipe 105 through the transport pipe 104. After being diverted by the diversion pipe 105, the water is sprayed onto the compacted lawn through the nozzles 106 to help the lawn and soil come into close contact and promote the growth of new roots.

[0027] The inner side of the fixed bracket 3 is symmetrically provided with guide grooves 301 and a rotating groove 302. The guide grooves 301 and the rotating groove 302 are connected. The inner wall of the rotating groove 302 is rotatably connected with a support shaft 303. The outer side of the support shaft 303 is fixedly connected with limiting teeth 304. The limiting teeth 304 are evenly distributed on the support shaft 303. When the support shaft 303 is inserted into the lawn roll, it is engaged and fixed with it by the limiting teeth 304. When the support shaft 303 is placed into the guide groove 301, it is pushed to slide in the guide groove 301 into the rotating groove 302, thus limiting the support shaft 303.

[0028] The fixed bracket 3 is internally connected to a limit screw 305 via a threaded connection. A knob 306 is fixedly connected to the top surface of the limit screw 305, and an arc-shaped limit seat 307 is fixedly connected to the bottom surface of the limit screw 305. The arc-shaped limit seat 307 is located directly above the support shaft 303. By rotating the knob 306, the limit screw 305 is driven to rotate, pushing the arc-shaped limit seat 307 downward to fit tightly against the surface of the support shaft 303, thus limiting the support shaft 303 without hindering its rotation.

[0029] A limiting slide rod 401 is slidably connected to the inner wall of the fixed bracket 3. The limiting slide rods 401 are symmetrically distributed on the fixed bracket 3. One end of the limiting slide rod 401 is fixedly connected to a limiting plate 402. A limiting spring 403 is slidably sleeved on the outer side of the limiting slide rod 401. The other end of the limiting slide rod 401 is fixedly connected to a limiting frame 404. A limiting roller 405 is rotatably connected to the inner side of the limiting frame 404. When the supporting shaft 303 is pushed to move in the guide groove 301, the lawn roll comes into contact with the limiting roller 405. The limiting frame 404 pushes the limiting slide rod 401 to slide outward, compressing the limiting spring 403. During the laying process, the elastic force of the limiting spring 403 pushes the limiting roller 405 to always keep it in contact with the lawn roll, assisting in the release of the lawn roll while preventing the lawn roll from becoming loose.

[0030] Working principle: According to Figure 1 , Figure 4 and Figure 5 As shown, during operation, the support shaft 303 is inserted into the inside of the lawn roll shaft and fixed by the limiting tooth 304. The support shaft 303 is then placed into the guide groove 301 and pushed to slide within the guide groove 301, so that the lawn roll contacts the limiting roller 405. The limiting frame 404 pushes the limiting slide rod 401 outward to compress the limiting spring 403. During the laying process, the elastic force of the limiting spring 403 pushes the limiting roller 405 to always keep it in contact with the lawn roll, assisting in the release of the lawn roll while preventing the lawn roll from becoming loose.

[0031] according to Figure 1 and Figure 4 As shown, the support shaft 303 is then pushed into the rotating groove 302. When the support shaft 303 is limited, the limit screw 305 is driven to rotate by rotating the knob 306, which pushes the arc-shaped limit seat 307 to move downward so that it is in close contact with the surface of the support shaft 303. This limits the support shaft 303 without hindering its rotation.

[0032] according to Figures 1-3 As shown, the device is connected and fixed to the power unit through the traction head 2, thereby driving the device to move and lay the lawn. During the movement, the lawn is flattened by the roller 7 so that the lawn is in full contact with the ground.

[0033] according to Figure 1 and Figure 3As shown, water is added to the water storage tank 101 through the water inlet pipe 102, and the water stored in the water storage tank 101 is extracted by the water pump 103. The water is then transported to the diversion pipe 105 through the transport pipe 104. During the movement, the water diverted through the diversion pipe 105 is sprayed onto the compacted lawn through the nozzle 106, which helps the lawn to make close contact with the soil, thereby promoting the growth of new roots.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
