Description

Technical Field

[0001] The utility model relates to the technical field of lawn laying, in particular to an auxiliary device for lawn laying. Background Art

[0002] Lawn refers to grass that is artificially planted or maintained and managed for greening and beautification. It is one of the symbols of the degree of civilization of a country or a city. It is suitable for beautifying the environment, gardening, purifying the air, conserving water and soil, and providing outdoor activities and sports venues; Chinese patent application number CN202022109012.1 discloses a lawn laying auxiliary device, including: a feed port arranged at the top of the main body; a feed track arranged below the feed port; a rotating wheel arranged below the feed track; a discharging track arranged below the rotating wheel; a discharging port arranged below the front of the discharging track; a pressure wheel arranged in front of the discharging port; and a pressure wheel arranged on the main body. A material storage box is provided at the rear of the body; a handrail is provided next to the material storage box, and a plurality of casters are provided under the body; the lawn laying auxiliary device is provided with a material storage box, in which a plurality of rolled natural lawns can be placed, thereby avoiding futile return transportation, and can realize single long-distance lawn laying, but during the laying process, it is still necessary to manually take out the lawn from the material storage box and place it in the feed port, and because the material storage box has a certain depth, it is very difficult to take the lawn at the bottom, which increases the labor burden of the workers. In addition, although the lawn is connected to the soil layer by rhizomes and has a certain pulling resistance, it is difficult to ensure that the lawn is not broken up when the rotating wheel is used to move it;

[0003] For this purpose, application number: 202221754450.6 discloses a lawn laying auxiliary device, including a box body, wherein universal wheels are rotatably installed on all four sides of the lower surface of the box body, a cover plate is movably connected to the upper surface of the box body, and handles are fixedly installed on both sides of the upper surface of the cover plate, and the interior of the box body is divided into a material storage chamber and a water storage chamber by a waterproof partition. The device is provided with a material storage mechanism, and the winding rod connected to the fixed frame can be rotated by manually rotating the rotating disk, so that the winding rod can be rotated, and the rotation of the winding rod can loosen the lawn body wound thereon, and the lawn body hanging on the conveying device will be conveyed to the guide plate and finally laid flat on the ground, avoiding manual picking during the laying process, reducing the burden of manual labor, and using the conveying device to transport the lawn instead of using the rotating wheel to move it, reducing the possibility of the lawn being scattered;

[0004] The lawn laying auxiliary device disclosed in the above patent wraps the lawn around a winding rod, releases the lawn by rotating the winding rod, and spreads the lawn on the ground in cooperation with a conveying device and a guide plate. This method has the following shortcomings when used: 1. Existing lawn rolls are usually not equipped with a winding rod when they are produced and sold. Therefore, each time the lawn is laid, the lawn needs to be wrapped around the winding rod before laying. During laying, a single person needs to rotate the winding rod to release the lawn, which is relatively labor-intensive. The lawn roll cannot be used directly for automatic release and laying operations. The degree of automation is low and cannot meet the use requirements. Based on the above situation, we have redesigned it and proposed an auxiliary device for lawn laying. Utility Model Content

[0028] Working principle: When in use, the entire device can be moved by the U-shaped handle and the four walking wheels. Before laying, first rotate the T-shaped fixing bolt 3 in the opposite direction. While the T-shaped fixing bolt 3 is rotating, it moves out of the threaded groove to release the fixation of the shielding plate 2. At this time, the shielding plate 2 can be rotated upward to release the obstruction of the mounting hole 1 and the water storage tank 101, and water can be added to the water storage tank 101. The lawn roll 103 to be laid can be placed in the arc-shaped lawn placement groove 5, and one end of the lawn roll 103 is pulled out and extends around the left side of the guide wheel 6 to the bottom of the mounting seat 100. At this time, one end of the lawn roll 103 is located on the left side of the driving friction wheel 7. Then, the wireless remote control switch above is controlled by the external remote control to control the first multi-stage electric telescopic rod 10 to open in the forward direction. The output shaft of the first multi-stage electric telescopic rod 10 drives the first U-shaped rod 8 and the driving friction wheel 7 to move to the left through the pressure sensor 11. When the driving friction wheel 7 moves to the left until it is in close contact with the lawn, the driving friction wheel 7 is restricted from continuing to move. At the same time, the first multi-stage electric telescopic rod 1 0 squeezes the pressure sensor 11, and the pressure sensor 11 detects the squeezing force and transmits the detected squeezing force to the controller 12. When the pressure reaches the preset value, it proves that the driving friction wheel 7 is in close contact with the lawn. At this time, the controller 12 controls the first multi-stage electric telescopic rod 10 to close, and the first U-shaped rod 8 moves to the left while driving the second multi-stage electric telescopic rod 13, the second U-shaped rod 15 and the compaction roller 14 to move to the left in sequence, and the lawn is located below the compaction roller 14. When laying, one end of the lawn roll 103 is fixed to one side of the ground, and then the wireless remote control switch below is controlled by the external remote control to control the second multi-stage electric telescopic rod 13 to open forward, and the output shaft of the second multi-stage electric telescopic rod 13 drives the compaction roller 14 to move downward through the second U-shaped rod 15 and squeeze the lawn downward, so that the lawn contacts the ground, and then the shielding plate 2 is rotated again to contact with the top of the mounting seat 100, and fixed by the T-shaped fixing bolt 3, and the shielding plate 2 can shield the lawn roll 103;

[0029] Then, the entire device can be pushed to move horizontally in the direction of laying through the U-shaped handle. During the movement of the entire device, the drive motor 9 is turned on in the positive direction, and the output shaft of the drive motor 9 drives the drive friction wheel 7 to rotate. While the drive friction wheel 7 rotates, it rubs the lawn downward, and there is a downward pulling force on the lawn. Under the pulling force, the lawn roll 103 rotates and releases the lawn. During the process of releasing the lawn, the lawn is gradually laid on the ground. The entire moving device also drives the compaction roller 14 to move leftward. While the compaction roller 14 moves leftward, it compacts the lawn released and laid on the ground, thereby achieving the effect of automatic laying and compacting of the lawn. By releasing the lawn through electric drive, there is no need for personnel to manually rotate and release the lawn, and there is no need to wind the lawn roll 103 around the winding shaft during laying, thereby reducing labor intensity and improving work efficiency.

[0030] During the laying and compacting process, the water pump 102 is turned on to extract water from the water storage tank 101. The extracted water is sprayed out through the horizontal pipe 16 and the sprinkler head 17 to spray the lawn and fix the roots. The entire process of laying, compacting and spraying and fixing the roots can be completed by moving the entire device in a single time. There is no need for step-by-step operation, which further improves work efficiency.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
