AI Technical Summary
The existing simple leveling device has poor flattening effect when passing through gravel, and is easily blocked by gravel and is pushed up, making it impossible to effectively flatten the planting layer.
At the right end of the channel steel, there are left and right horizontal positioning steel bars, which extend to the right to the top of the drainage ditch, and then turn downward into the drainage ditch to form a positioning part. The left side wall of the positioning part is equipped with puncture steel bars, and the puncture steel bars extend to the left and puncture into the left inner wall of the drainage ditch, thus being limited to the upper and lower directions and providing vertical support force.
Even if the channel steel tends to be blocked and pushed up when passing through gravel, the vertical support provided by the punctured steel bars prevent the channel steel from being pushed up by gravel, which can push the gravel forward and smoothly flatten the planting layer.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of natural turf football field construction, in particular to a simple leveling device suitable for a planting layer of a natural turf football field. Background Art
[0002] The natural grass football field has multiple layers, and the surface layer is the planting layer. After the construction workers have built the planting layer, they use a simple leveling device to flatten the planting layer, and then plant natural grass on the planting layer to complete the construction of the natural grass football field. Figure 1 As shown, left and right transverse channel steels 3 are placed on the planting layer 1 behind the tractor 2, and two ropes 4 are tied to the two ends of the channel steels 3, and the two ropes 4 are tied to the hooks at the rear end of the tractor 2. The tractor 2 moves forward, and the channel steels 3 are pulled forward by the tractor 2 to flatten the part of the planting layer 1 that is passed; the tractor 2 drives the channel steels 3 to complete the unpassed area of the planting layer 1, and then the entire area of the planting layer 1 is flattened, and then natural grass is planted on the planting layer 1, and a natural grass football field is built. The defect of the prior art is that the channel steels 3 only rely on their own weight to flatten the planting layer 1, and sometimes a small amount of gravel is accidentally mixed into the planting layer 1. If the channel steels 3 pass through the gravel during the process, they will be blocked by the gravel and lifted up. They will move along the top surface of the gravel until they pass over the gravel and fall to the ground before they can contact the planting layer 1 again to continue the flattening. Therefore, the flattening effect of the simple leveling device is not good when passing through the gravel. Utility Model Content
[0003] The inventor thought that the natural grass football field was originally surrounded by drainage ditches, and the drainage ditches were similar in shape to the outline of the football field, that is, both were rectangular and each side was parallel to each side of the football field. Therefore, the original drainage ditches could be used to assist in positioning the channel steel to prevent the channel steel from being blocked by the gravel and lifted up.
[0004] The utility model aims to provide a simple leveling device suitable for the planting layer of a natural grass football field. The device is made of only common building materials on construction sites, and even if the channel steel encounters gravel during its movement, it is not easy to turn to an oblique upper direction and bounce forward, thereby improving the flattening effect of the simple leveling device when passing through gravel.
[0005] A simple leveling device suitable for the planting layer of a natural grass football field comprises left and right transverse channel steels arranged behind a tractor, two ropes are tied at both ends of the channel steels, and the tractor is connected by the two ropes; the tractor and the channel steels are both located on the planting layer of the natural grass football field, and the channel steels are driven forward by the tractor to flatten a part of the planting layer in the path, and the device is characterized in that: left and right transverse positioning steel bars are arranged at the right end of the channel steels, the positioning steel bars extend to the right to the top of the drainage ditch on the right side of the planting layer of the football field, and then turn downward to extend into the drainage ditch to form a positioning part, and a piercing steel bar is arranged on the left side wall of the positioning part, and the piercing steel bar extends to the left until it pierces into the left inner wall of the drainage ditch, thereby being limited in the up and down directions.
[0006] Furthermore, the positioning steel bar is specifically installed at the right end of the top wall of the channel steel.
[0007] Furthermore, the channel steel is 6 meters long, the left and right lateral parts of the positioning steel bars are 3.5 meters long, and the positioning length is 1.5 meters long.
[0008] Further, two ropes are specifically connected to a hook at the rear end of the tractor.
[0009] Furthermore, the piercing steel bar is 0.3 meters long.
[0010] The beneficial effect is that the piercing steel bar extends to the left and pierces the left inner wall of the drainage ditch, thereby being limited in the up and down directions, and the piercing steel bar is connected to the channel steel through the positioning steel bar; even if the channel steel has a tendency to be blocked and lifted up when passing through the gravel, the channel steel will not be lifted up by the gravel because of the vertical downward supporting force provided by the piercing steel bar, so that the gravel can be pushed to continue moving forward and the planting layer in the path can be flattened smoothly.

[0018] The invention of the utility model is further described in detail below in conjunction with specific implementation methods.
[0019] like Figure 3 and Figure 4 As shown, the planting layer 1 of the natural grass football field is rectangular and surrounded by a drainage ditch 5 which is also rectangular. A left and right horizontal channel steel 3 is provided behind the tractor 2. Two ropes 4 are tied to the left and right ends of the channel steel 3, respectively. The two ropes 4 are tied to the hooks at the rear end of the tractor 2. The tractor 2 and the channel steel 3 are both located on the planting layer 1 of the football field, and the right end wall of the channel steel 3 fits the right edge of the planting layer 1 of the football field. A 5-meter-long positioning steel bar 6 is installed at the right end of the top wall of the channel steel 3, as shown in FIG. Figure 2 As shown, 3.5 meters of it is horizontal, and this part extends to the right to the drainage ditch 5 on the right side of the planting layer 1 of the football field. The remaining 1.5 meters turns downward and extends into the drainage ditch 5 to form a positioning part 7. The left wall of the positioning part 7 is equipped with a piercing steel bar 8, which penetrates into the left inner wall of this section of the drainage ditch 5 and is limited in the vertical direction. The tractor 2 moves forward, and the channel steel 3 is driven forward by the tractor 2 to flatten the planting layer 1 on the path. The piercing steel bar 8 moves forward with the channel steel 3, and in this process, the channel steel 3 is limited in the vertical direction. Even if the channel steel 3 is blocked by gravel, it will not be lifted up by the gravel, but pushes the gravel forward to smoothly flatten the planting layer 1 on the path.
[0020] The channel steel 3 moves forward as described above, flattening the portion of the planting layer 1 of the football field near the right edge, such as Figure 5 and Figure 6 As shown, then return to the rear end of the soccer field planting layer 1 and start moving forward from the left side of the previous forward movement path for the next flattening. At this time, the left and right lateral parts of the positioning steel bar 6 are not enough to extend above the drainage ditch 5 on the right side of the soccer field planting layer 1, so it is necessary to use connecting steel bars 9 to connect the right end of the top wall of the channel steel 3 and the left end of the positioning steel bar 6. Repeat the flattening according to the above method until the channel steel 3 has flattened the entire area of the soccer field planting layer 1; or, Figure 2 The left end of the channel steel 3 in the middle is spliced with multiple channel steels 3 in sequence, and the spliced channel steel is as wide as the right half of the planting layer 1 of the football field. It is installed on a tractor 2 and driven forward by it to flatten the right half of the planting layer 1 of the football field at one time, and then the left half of the planting layer 1 of the football field is flattened in the same process. Then natural grass is planted on the planting layer 1, and the natural grass football field is built.
[0021] It should be noted that when the channel steel 3 flattens the left half of the planting layer 1 of the football field, for example, when the portion of the planting layer 1 of the football field near the left edge is flattened, Figure 2 The positioning steel bar 6 is rotated 180 degrees left and right, the left end wall of the channel steel 3 fits the left edge of the planting layer 1 of the football field, the left end of the positioning steel bar 6 extends to the top of the drainage ditch 5 on the left side of the planting layer 1 of the football field, and the positioning part 7 extends into this section of the drainage ditch 5. The piercing steel bar 8 on the positioning part 7 extends to the right after rotation and penetrates into the right inner wall of this section of the drainage ditch 5, thereby being limited in the up and down directions.
[0022] One of the advantages of the simple leveling device of the utility model is that it is made of common building materials on construction sites, the materials are easy to obtain, and the manufacture is simple.
[0023] The above is only an implementation method of the utility model, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the utility model, which still fall within the scope of patent protection.
