Description

Technical Field

[0001] This utility model relates to the field of cutting boards, and in particular to a cutting board for airport backhoe excavation. Background Technology

[0002] In airport construction, cutting boards are used to improve the flatness of the airport site. By installing them on a backhoe excavator, efficient and precise land leveling work can be carried out. They are particularly suitable for areas such as airport runways and aprons where the flatness of the ground is extremely important.

[0003] However, during the leveling process, the scrapers on the cutting slab are easily damaged by hard objects such as sand and stones in the site. After the scrapers are damaged, the flatness of the airport site can be affected. At this time, the cutting slab needs to be replaced. However, the existing cutting slabs are all integral pieces, and the scraper part cannot be replaced separately. Such replacement would waste a lot of resources and be detrimental to the environment.

[0004] Therefore, it is necessary to design an airport backhoe excavator with a scraper section that can be replaced individually to save resources. Utility Model Content

[0005] To overcome the shortcomings of existing cutting boards, which are all integral pieces and cannot have their scraper parts replaced individually, resulting in wasted resources and environmental problems, the technical problem to be solved is to provide an airport backhoe excavator cutting board that allows for the individual replacement of the scraper parts, thus saving resources.

[0006] The technical solution is: an airport backhoe excavator for cutting soil at airport sites, comprising a cutting plate, connectors, side plates, a scraper, a locking mechanism, and a locking mechanism. Connectors are connected to the left and right rear sides of the cutting plate to fix the cutting plate to the excavator. Side plates are connected to the left and right sides of the cutting plate. A scraper is detachably installed between the lower parts of the side plates. The scraper is located on the lower side of the cutting plate. A locking mechanism for locking the scraper is provided on the lower part of the cutting plate. A locking mechanism for locking the scraper is provided on the locking mechanism.

[0007] Furthermore, the scraper is angled.

[0008] Furthermore, the positioning mechanism includes a positioning block, a slider, and a first telescopic spring. Positioning blocks are connected to the lower left and right sides of the cutting plate, and sliders are slidably connected to the left and right sides of the positioning blocks. The sliders are engaged with the scraper, and the first telescopic spring connects the positioning block and the slider.

[0009] Furthermore, it also includes a first guide rod and a sleeve. The middle part of the positioning block is connected to two first guide rods, one above the other. Sleeves are slidably connected to both sides of the first guide rods, and the sleeves are slidably connected to the adjacent sliders.

[0010] Furthermore, the locking mechanism includes a second guide rod, a connecting rod, a second telescopic spring, a limiting plate, and a pusher. The second guide rod is connected to the upper middle part of the positioning block, and the connecting rod is slidably connected to the second guide rod. The second telescopic spring is connected between the connecting rod and the second guide rod. Pushers are connected to both the left and right sides of the connecting rod, and limiting plates are connected to the lower side of the pushers. The limiting plates are engaged with the slider.

[0011] Furthermore, the side of the limiting plates that are close to each other is an inclined plane, and the side that is far from each other is a flat plane.

[0012] The beneficial effects of this utility model are as follows: 1. By controlling the push frame to move upward, the limiting plate and the slider are disengaged. At this time, the first telescopic spring contracts and drives the slider to move inward. The slider will then disengage from the scraper. The scraper can then move downward and disengage from the positioning block, thus allowing the scraper to be disassembled and replaced. This eliminates the need to replace an entire flat cutting board, thereby reducing resource waste.

[0013] 2. This utility model no longer controls the push frame. When the second telescopic spring returns to its original state, it will drive the push frame, the limiting plate and the connecting rod to move downward. When the limiting plate moves downward, the side that is close to each other is inclined, which squeezes the slider to move outward. The first telescopic spring is compressed, which makes the slider get stuck in the scraper, thus automatically fixing the scraper. The operation is simple and convenient. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] An airport backhoe excavator for cutting the airport ground plane, such as... Figure 1-5 As shown, the device includes a cutting plate 1, a connector 2, a side plate 3, a scraper 4, a locking mechanism, and a locking mechanism. The connector 2 is connected to both the left and right rear sides of the cutting plate 1. The connector 2 is used to fix the cutting plate 1 to the excavator. The side plates 3 are connected to both the left and right sides of the cutting plate 1. The scraper 4 is detachably installed between the lower parts of the side plates 3. The scraper 4 is inclined and located on the lower side of the cutting plate 1. The lower part of the cutting plate 1 is provided with a locking mechanism for locking the scraper 4. The locking mechanism is provided with a locking mechanism for locking.

[0022] The positioning mechanism includes a positioning block 5, a slider 6, and a first telescopic spring 9. The positioning block 5 is connected to the lower left and right sides of the cutting plate 1. The slider 6 is slidably connected to the left and right sides of the positioning block 5. The slider 6 is engaged with the scraper 4. The first telescopic spring 9 is connected between the positioning block 5 and the slider 6.

[0023] It also includes a first guide rod 7 and a sleeve 8. The middle part of the positioning block 5 is connected to two first guide rods 7, one above the other. The sleeves 8 are slidably connected to the left and right sides of the first guide rods 7. The sleeves 8 are slidably connected to the adjacent sliders 6.

[0024] The locking mechanism includes a second guide rod 10, a connecting rod 11, a second telescopic spring 12, a limiting plate 13, and a pusher frame 14. The second guide rod 10 is connected to the upper middle part of the positioning block 5. The connecting rod 11 is slidably connected to the second guide rod 10. The second telescopic spring 12 is connected between the connecting rod 11 and the second guide rod 10. The pusher frame 14 is connected to both the left and right sides of the connecting rod 11. The limiting plate 13 is connected to the lower side of the pusher frame 14. The limiting plate 13 is engaged with the slider 6. The side of the limiting plate 13 that is close to each other is an inclined surface, and the side that is far away from each other is a flat surface.

[0025] When using this device, the cutting plate 1 and the scraper 4 are fixed to the excavator by connecting the connector 2, thus enabling the device to be used. After a certain period of use, the scraper 4 will wear down, affecting its performance. Initially, the first telescopic spring 9 is in a stretched state. At this time, the push frame 14 can be moved upward, which will drive the limiting plate 13 and the connecting rod 11 to move upward. The second telescopic spring 12 is stretched, and the limiting plate 13 will disengage from the slider 6. At this time, the first telescopic spring 9 retracts, which will drive the slider 6 to move inward. At this time, the slider 6 will disengage from the scraper 4, and the scraper 4 can then move inward. The scraper 4 can be disassembled and replaced by moving downwards, thus eliminating the need to replace the entire cutting plate 1 and reducing resource waste. After replacing the scraper 4, the scraper 4 is moved upwards so that the positioning block 5 can be inserted into the scraper 4. Then, the push frame 14 is no longer controlled. At this time, the second telescopic spring 12 returns to its original position, which will drive the push frame 14, the limiting plate 13 and the connecting rod 11 to move downwards. When the limiting plate 13 moves downwards, the side that is close to each other is inclined, which squeezes the slider 6 to move outwards. The first telescopic spring 9 is compressed, which makes the slider 6 lock into the scraper 4, thereby fixing the scraper 4. The operation is simple and convenient.

[0026] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
