[0002] Lawn refers to grass that is artificially planted or maintained for greening and beautification. As one of the elements of the ecosystem, lawn has many important functions and plays a very important role in improving the ecological and living environment of the city.
[0003] The lawn is rolled up by the winding roller to form a grass roll. The grass roll is usually laid on the ground by a laying machine. The existing laying machine includes a trailer, a pressing roller and two clamping parts. The trailer is equipped with a bracket; the two clamping parts are movably installed on the opposite sides of the bracket, and the pressing roller is rotatably installed on the bracket. When working, the grass roll is placed inside the bracket, and then the two clamping parts are close to each other to clamp the two ends of the grass roll, that is, the grass roll and the bracket are fixed; the staff pulls out one end of the lawn and puts it on the ground through the gap between the pressing roller and the ground. Start the trailer, the winding roller rotates to make the lawn detach from the winding roller, so that the lawn can be laid on the ground; and the pressing roller contacts the upper surface of the lawn and presses the lawn to the ground, improving work efficiency.
[0004] However, since some rolls are heavy, even weighing more than 600kg, the lifting bracket makes it difficult to pull the lawn out from between the compaction roller and the ground, which needs to be improved. Utility Model Content
[0005] In order to facilitate the extraction of lawn from between the compacting roller and the ground, the present application provides a grass roll laying machine.
[0006] The straw roll laying machine provided in this application adopts the following technical solution:
[0007] A grass roll laying machine includes a trailer, a bracket, a clamping assembly and a pressure roller, wherein the bracket is installed on the trailer through a lifting assembly, the clamping assembly is installed on the bracket, and the clamping assembly is used to clamp the opposite ends of the grass roll; the bracket is equipped with two sliding blocks, and the sides of the two sliding blocks close to each other are vertically provided with sliding grooves; the two ends of the pressure roller are respectively slidably installed in the sliding grooves, and the bracket is equipped with a lifting assembly for changing the position of the pressure roller in the sliding groove.
[0008] By adopting the above-mentioned technical solution, when the grass roll and the laying machine are connected, the trailer is started to move toward one side of the grass roll and the lifting assembly is started to lift the bracket, so that the grass roll can enter the bracket. At this time, the clamping assembly is started to fix the grass roll and the bracket; at this time, the lifting assembly is started to change the position of the pressure roller in the slide groove, so that there is a gap between the pressure roller and the ground when it is lifted, so that the lawn passes through the pressure roller and the ground, and the lifting assembly is used again to make the pressure roller contact with the surface of the lawn, so as to compact the lawn during the laying process on the ground.
[0009] The use of the lifting assembly facilitates the lifting of the compacting roller in the height direction, so as to facilitate the passage of the lawn between the compacting roller and the ground, thereby reducing the need to lift the entire support, reducing work difficulty, and improving work efficiency.

[0011] By adopting the above technical solution, the eccentric wheel can be rotated on the upper surface of the fixed platform by pressing the driving roller. Since the distances from the center of the eccentric wheel to each position of the outer peripheral wall of the eccentric wheel are different, the distance between the center of the eccentric wheel and the fixed platform changes; thereby, the sliding block connected to the eccentric wheel can slide in the sliding groove, thereby increasing the gap between the clamping roller and the ground, so that the lawn in the initial stage can pass through the gap between the clamping roller and the ground.
[0012] Optionally, the eccentric wheel is provided with a cut angle, and the cut angle surface is configured as a limiting portion for abutting against an upper surface of a fixed platform.
[0013] By adopting the above technical solution, when the pressing roller is lifted, the limiting part abuts against the upper surface of the fixed platform, thereby reducing the rotation of the eccentric wheel during the process of the lawn passing between the pressing roller and the ground.
[0014] Optionally, a spring is provided between the inner wall of the slide groove and the pressing roller, and the elastic force of the spring is used to drive the pressing roller to move toward one side of the ground.
[0015] By adopting the above technical solution and setting a spring, the elastic force of the spring can make the clamping roller press against the upper surface of the lawn, reduce the situation where the clamping roller jumps in the slide groove during the lawn laying process, and maintain the clamping effect of the clamping roller.
[0016] Optionally, the clamping assembly includes a driving member and two clamping frames, and the two clamping frames are movably mounted on the bracket; the driving member is used to drive the two clamping frames to approach each other, and a clamping rod is rotatably mounted on one side of the two clamping frames approaching each other, and the clamping frame is installed with a motor for driving the clamping rod to rotate.
[0017] By adopting the above technical solution, when the grass roll is placed inside the bracket, the driving member is driven to make the two clamping frames approach each other, so that the two clamping rods are respectively inserted into the two ends of the tightening roller; and in the process of moving the trailer, the motor is driven at the same time to make the grass roll rotate in the bracket, so as to loosen the lawn from the winding roller and lay it on the ground.
[0018] Optionally, the clamping frame is installed with a positioning plate.
[0019] By adopting the above-mentioned technical solution and setting a positioning plate, it is possible to ensure that the lawn is positioned before laying and released at an appropriate position, thereby improving work efficiency; and the positioning plate can change with the movement of the clamping frame, that is, the distance between the two positioning plates changes with the length of the lawn, thereby improving the practicability of the paving machine.
[0020] Optionally, the maximum distance between the two clamping frames is smaller than the length of the pressure roller.
[0021] By adopting the above technical solution, during the lawn laying process, the compaction roller can be pressed against the upper surface of lawns of different sizes to compact lawns of different lengths, thereby further improving the practicality of the paving machine.
[0022] Optionally, the lifting assembly includes a first cylinder, which is mounted on the trailer, and a movable plug of the first cylinder is fixed to the bracket.
[0023] By adopting the above technical solution, the first cylinder is started to lift the bracket so that the grass roll enters the inside of the bracket.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 2. By setting a spring, the elastic force of the spring can make the pressing roller press against the upper surface of the lawn, reduce the situation where the pressing roller jumps in the slide groove during the lawn laying process, and maintain the pressing effect of the pressing roller.

DETAILED DESCRIPTION
[0033] The following is combined with Figure 1-5 This application is described in further detail.
[0034] The embodiment of the present application discloses a straw roll laying machine.
[0035] Reference Figure 1 and Figure 2 A grass roll laying machine includes a trailer 1, a bracket 2, a clamping assembly 3 and a pressing roller 4. The trailer 1 is equipped with a sliding frame 11, the bracket 2 is slidably connected to the sliding frame 11, and the side of the bracket 2 away from the sliding frame 11 is provided with an opening; the trailer 1 is equipped with a lifting assembly 12.

Starting the first cylinder can drive the bracket 2 to slide in the sliding frame 11, and can make a distance between the bracket 2 and the ground, so that the bracket 2 is located above the grass roll; and restarting the first cylinder can make the grass roll enter the inside of the bracket 2.
[0036] Reference Figure 2 The clamping assembly 3 includes a driving member 31 and two clamping frames 32, and the two clamping frames 32 are both slidably installed on the bracket 2; the driving member 31 is configured as a double-headed cylinder, and the double-headed cylinders are both fixed on the bracket 2, and the movable plugs of the double-headed cylinders are respectively fixed to the two clamping frames 32.
[0037] Reference Figure 3A clamping rod 33 is rotatably installed on the side where the two clamping frames 32 are close to each other. The cross-section of the clamping rod 33 is polygonal. The clamping frame 32 is installed with a motor 34 for driving the clamping rod 33 to rotate; both ends of the winding roller are provided with plug-in slots for the clamping rod 33 to be plugged in. Starting the driving member 31 can make the two clamping rods 33 be respectively plugged into the two ends of the winding roller, and starting the motor 34 can make the clamping rod 33 rotate, thereby making the grass roll rotate in the bracket 2.
[0038] Reference Figure 1 and Figure 3 Both clamping frames 32 are fixed with positioning plates 35, and the two positioning plates 35 are extended toward one side of the ground; the setting of the positioning plates 35 can make one side of the lawn on the trailer 1 abut against one side of the lawn laid on the ground, thereby improving the rapid positioning of the lawn on the trailer 1; and the spacing between the two positioning plates 35 can keep the size of the lawn from changing, so that the length between the two positioning plates 35 remains the same as the length of the lawn, thereby improving the practicality of the paving machine.
[0039] Reference Figure 4 Two sliding blocks 5 are fixed on the side of the bracket 2 away from the sliding frame 11, and the two sliding blocks 5 are respectively located on both sides of the bracket 2; a sliding groove 51 is opened on the side where the two sliding blocks 5 are close to each other, and the extension direction of the sliding groove 51 is perpendicular to the ground; sliding blocks 52 are installed at both ends of the clamping roller 4, the sliding blocks 52 are rotatably connected to the clamping roller 4, and the sliding blocks 52 are slidably installed in the sliding groove 51.
[0040] The sliding block 5 is installed with a spring 53, one end of the spring 53 is fixed to the side of the sliding block 52 away from the ground, and the other end of the spring 53 is fixed to the end of the sliding groove 51 away from the ground; the elastic force of the spring 53 is used to drive the sliding block 52 to move toward one side of the ground, reducing the rotation of the eccentric wheel 22 during the process of the lawn passing through the pressure roller 4 and the ground, so that the pressure block is normally pressed against the upper surface of the lawn, thereby improving the compaction effect of the lawn laid on the ground.
[0041] Reference Figure 5 One of the sliding blocks 5 is fixed with a fixed platform 54, and the fixed platform 54 is located on the side of the sliding block 5 close to the sliding frame 11; the bracket 2 is installed with a lifting component 21, and the lifting component 21 includes an eccentric wheel 22 and a driving rod 23. A driving groove 55 is opened on the side of the sliding block 5 close to the fixed platform 54, and the driving groove 55 is connected with the sliding groove 51; a movable rod 56 is slidingly installed in the sliding groove 51, and the movable rod 56 is fixed to the sliding block 52; the eccentric wheel 22 is rotatably connected to the movable rod 56, and the outer peripheral surface of the eccentric wheel 22 abuts against the upper surface of the fixed platform 54, and one end of the driving rod 23 is fixed to the side of the eccentric wheel 22 away from the movable rod 56.
[0042] When the distance between the center of the eccentric wheel 22 and the fixed platform 54 is at the maximum value, a cut angle is formed between the outer peripheral surface of the eccentric wheel 22 and the contact surface of the fixed platform 54, and the cut angle surface is set as the limit portion 24. When the pressure roller 4 is lifted to make the limit portion 24 contact with the upper surface of the fixed platform 54, the position of the eccentric wheel 22 on the fixed platform 54 can be fixed, and the rotation of the eccentric wheel 22 is reduced when the lawn passes between the pressure roller 4 and the ground.
[0043] In this embodiment, the length of the pressure roller 4 is greater than the maximum distance between the two clamping frames 32. During the lawn laying process, the pressure roller 4 can be pressed against the upper surface of lawns of different sizes to compact lawns of different lengths, further improving the practicality of the paving machine.
[0044] The implementation principle of a grass roll laying machine in the embodiment of the present application is:
[0045] After the grass roll is fixed to the bracket 2, the pressing rod is pressed so that the limiting portion 24 of the eccentric wheel 22 abuts against the upper surface of the fixed platform 54, thereby increasing the distance between the pressing roller 4 and the ground and facilitating the lawn to pass between the pressing roller 4 and the ground; then the pressing rod is used again to rotate the eccentric wheel 22 on the upper surface of the fixed platform 54, so that the pressing roller 4 abuts against the surface of the lawn and facilitates compaction of the lawn during laying on the ground.
[0046] The use of the lifting assembly 21 facilitates lifting the pressing roller 4 in the height direction, so as to facilitate passing the lawn between the pressing roller 4 and the ground, thereby reducing the need to lift the entire bracket 2, reducing work difficulty, and improving work efficiency.
[0047] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
