Description

Technical Field

[0001] The utility model relates to the field of natural lawn football field construction, in particular to a bulldozer laser guiding device used for building a drainage slope of a football field. Background Art

[0002] Patent document CN101230584A discloses a laser-controlled land-leveling bulldozer, which is equipped with a laser receiver on the shovel head of the bulldozer, and a laser transmitter is arranged outside the construction position. The laser transmitter emits a laser beam toward the laser receiver, and the laser receiver controls the bulldozer to advance in a straight line at the construction position under the guidance of the laser beam. The second paragraph of the specific implementation method discloses that "when the laser signal transmitter is set to emit a certain slope signal, the slope surface leveling operation can be performed". The football field has two drainage slopes at the front and rear, so the center line is high and the front and rear ends are low. However, the bulldozer in the above patent document can only move towards a fixed slope. If it is used to build a drainage slope, it is necessary to set two laser transmitters at the front and rear ends of the football field respectively. The two bulldozers are respectively arranged at the two ends of the football field, and each moves towards the center line with a fixed slope until it converges. The defect of the prior art is that two laser transmitters need to be set at the front and rear ends of the football field respectively, and the number of laser transmitters is large, and the equipment cost is high. Utility Model Content

[0003] The utility model aims to provide a bulldozer laser guiding device for constructing a drainage slope of a football field. It only needs to arrange a laser transmitter at one end of the football field, thereby reducing the number of laser transmitters and thus reducing costs.

[0004] A bulldozer laser guidance device for constructing a drainage slope for a football field comprises a laser transmitter, which is arranged in front of the football field and emits a laser beam toward a laser receiver on the shovel head of the bulldozer on the football field to guide the bulldozer to move forward. A first vertical cylinder is arranged in front of the football field, and the middle part of the bottom wall of the laser receiver is hinged on the top of the first vertical cylinder. The laser receiver is flipped up and down around the hinge to adjust the slope of the laser beam emission, and the first vertical cylinder drives the laser receiver to rise and fall to adjust the height position of the laser beam.

[0005] Furthermore, a second vertical cylinder is arranged in front of the first vertical cylinder and arranged side by side therewith, the front end of the bottom wall of the laser emitter is hinged to the top wall of the second vertical cylinder, and the second vertical cylinder drives the laser emitter to perform the up and down flipping around the hinge.

[0006] Furthermore, it comprises left and right lateral tracks, and the first vertical cylinder and the second vertical cylinder are mounted on the tracks and can move along the tracks.

[0007] Furthermore, the track length is 72 to 74 meters.

[0008] Furthermore, the slope range of the laser receiver turning up and down around the hinge is -0.5% to 0.5%.

[0009] The beneficial effect is that the laser transmitter only needs to be set on the front side of the football field. By adjusting its own height position and the slope of the laser emission, the bulldozer can be guided to move on the rearward drainage slope and the forward drainage slope respectively, without the need to set up two rows of laser transmitters in front and behind the football field respectively as in the background technology, thereby reducing the number of laser transmitters and saving equipment costs.

[0014] The invention of the utility model is further described in detail below in conjunction with specific implementation methods.

[0015] like Figure 1 As shown, the football field is horizontal in front and back, the part behind the center line 16 is the rearward drainage slope 12, and the part in front of the center line 16 is the forward drainage slope 14. When building a football field, it is necessary to first build the forward and backward drainage slopes 14 and 12, and the construction process is detailed below.

[0016] There are horizontal tracks 4 in front of the football field. The length of the track 4 is 72 to 74 meters, which is equal to the standard width of the football field. Figure 2As shown, the first and second vertical cylinders 3 and 2 are movably mounted on the track 4. A laser transmitter 1 is arranged above the first and second vertical cylinders 3 and 2. The middle of the bottom wall of the laser transmitter 1 is hinged to the top of the first vertical cylinder 3 to form a first hinge, and the front end of the bottom wall is hinged to the top of the second vertical cylinder 2. The bulldozer 10 is located at the rear end of the part near the right edge of the football field, with the shovel head 9 facing forward, and the top wall of the shovel head 9 is equipped with a laser receiver 13 and a controller (not shown in the figure). The second vertical cylinder 2 extends upward to drive the laser emitter 1 to turn upside down around the first hinge to become a state with the front higher and the back lower. Then the laser emitter 1 emits a laser beam 11 at an angle of 0.3° to 0.5° downward and backward (the slope of the laser beam 11 is -0.3% to -0.5%). The laser beam 11 reaches the laser receiver 13 and is received. The laser receiver 13 transmits a signal to the controller. The controller controls the shovel head 9 to adjust to an angle of 0.3% to 0.5% upward and forward (the horizontal line is 0°, and the slope of the laser beam 11 is 0.3% to 0.5%) according to the signal. The bulldozer 10 is guided by the laser beam 11 to move forward to the center line 16, thereby constructing the portion of the backward slope 12 close to the right edge. Figure 3 As shown, the second vertical cylinder 2 retracts downward to drive the laser emitter 1 to turn upside down around the first hinge to become a state with the front lower and the back higher, then the laser emitter 1 turns obliquely upward and backward to a slope of 0.3% to 0.5%, and emits a laser beam 11; the first and second vertical cylinders 3 and 2 retract downward together to drive the laser emitter 1 to move downward so that the height position of the laser beam 11 matches the laser receiver 13, and the laser beam 11 arrives at the laser receiver 13 and is received. The laser receiver 13 transmits a signal to the controller, and the controller controls the shovel head 9 to adjust to a slope of 0.3% to 0.5% obliquely downward and forward according to the signal. The bulldozer 10 is guided by the laser beam 11 to move forward to the front end of the football field to build the part close to the right edge of the forward drainage slope 14. Then the bulldozer 10 leaves the football field from the front end of the football field, detours to the rear end of the football field, and bulldozes the remaining unconstructed parts of the football field from the front to the back according to the above steps, and the forward and backward drainage slopes 14 and 12 are built. Finally, natural turf is planted on the two drainage slopes 14 and 12, which are inclined forward and backward, to build a natural turf football field.

[0017] 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.
