Description

Technical Field

[0001] This invention relates to construction equipment, specifically to an auxiliary tool for a backhoe excavator and its construction method. Background Technology

[0002] In narrow pits, the bucket of a backhoe excavator can only be raised, lowered, and swung left and right after it extends into the pit. It cannot perform normal operations such as leveling, soil removal, and soil disposal. Therefore, it is necessary to manually enter the pit to operate small handheld equipment for construction, which is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary tool for a backhoe excavator and its construction method. This tool can assist the backhoe excavator in leveling, soil removal, and soil disposal operations in narrow pit areas, avoiding manual labor and can be reused.

[0004] The technical solution adopted in this invention is: An auxiliary tool for backhoe excavators, used to be installed on the underside of the bucket floor plate of a backhoe excavator to assist in its operation, includes two housings. The housings are back-to-back on one side below the center of the bucket, and open on the other side below the edge of the bucket, with a hinged linkage door on the top. The front and rear housings are also open, with gravity doors hinged on the top. Suspension rods are fixedly distributed on the top surface, passing through the bucket floor plate and fitted with nuts at the upper part of the bucket floor plate. The linkage doors are hinged to linkage rods, which pass through the bucket floor plate and are fitted with nuts at both the upper and lower sides of the bucket floor plate. When the bucket floor plate is raised, the housings are suspended under the bucket floor plate by the suspension rods and nuts; the linkage rods drive the linkage doors to open the sides of the housings. When the bucket floor plate is lowered to the top of the housings, the linkage rods drive the linkage doors to close the sides of the housings. When the bucket floor plate is laid flat, the gravity doors close the front and rear of the housings under gravity. When the bucket floor plate swings back and forth, the gravity doors swing open.

[0005] Preferably, both housings have ramps on the bottom side edges below the bucket edge.

[0006] Preferably, the housing, linkage door, gravity door, suspension rod, linkage rod, nut, and related hinges are all made of stainless steel.

[0007] The construction method of the above-mentioned backhoe excavator auxiliary tool is as follows: First, install the backhoe excavator auxiliary tool on the underside of the bottom plate of the backhoe excavator bucket; then operate the backhoe excavator, first extend the bucket into the narrow pit, then press down the bucket so that the bottom plate of the bucket descends to the top surface of the box, the linkage rod drives the linkage door to close the side of the box, then swing the bucket left and right to level the pit using the box and pile the excess soil on both sides, then raise the bucket so that the linkage rod drives the linkage door to open the side of the box without the box leaving the ground in the pit, then swing the bucket left and right to shovel the soil on both sides into the box, then raise the bucket and transfer it outside the pit, then swing the bucket back and forth to dump the soil inside the box through the gravity door.

[0008] Furthermore, the installation method of the auxiliary tools for the backhoe excavator is as follows: First, hinge the linkage door, gravity door, and linkage rod on the housing. Then, fix the suspension rod on the housing. Hinge the linkage rod on the linkage door and fit a nut on the linkage rod. Make through holes on the bucket bottom plate corresponding to the suspension rod and linkage rod. Then, pass the suspension rod and linkage rod upward through the corresponding through holes. Next, adjust the position of the nut on the lower side of the bucket bottom plate on the linkage rod so that when the bucket bottom plate is lowered to the top surface of the housing, the linkage rod can drive the linkage door to close the side of the housing. Then, keep the position of the nut and fit the remaining nuts on the suspension rod and linkage rod, and let the remaining nuts stick to the upper side of the bucket bottom plate.

[0009] The beneficial effects of this invention are: This tool assists backhoe excavators in leveling, soil removal, and soil disposal operations in narrow pits, avoiding manual labor and allowing for reuse. Attached Figure Description

[0018] Example 1 For some confined pit sites (such as narrow ditches, between piles, etc.), the bucket of a backhoe excavator can only be raised, lowered, and swung left and right after extending into the pit, making it impossible to perform normal leveling, soil removal, and disposal operations. The current solution involves manual entry into the pit to operate small handheld equipment, which is time-consuming and labor-intensive. To solve these problems, this embodiment discloses an auxiliary tool for a backhoe excavator, such as... Figure 1 As shown, it is used to be installed on the underside of the bottom plate 1 of the bucket of a backhoe excavator and to assist the backhoe excavator in operation.

[0019] The auxiliary tools for a backhoe excavator include a housing 2, a linkage door 3, a gravity door 4, a suspension rod 5, a nut 6, and a linkage rod 7; among which: (e.g.) Figures 1 to 3 As shown, the two boxes 2 are back to back on one side below the center of the bucket, and open on the other side below the edge of the bucket with a hinged linkage door 3 on the top. The front and rear are open and gravity doors 4 are hinged on the top. The top surface is distributed with fixed suspension rods 5. The suspension rods 5 pass through the bucket bottom plate 1 and are fitted with nuts 6 on the upper side of the bucket bottom plate 1. The linkage door 3 is hinged with a linkage rod 7. The linkage rod 7 passes through the bucket bottom plate 1 and is fitted with nuts 6 on both the upper and lower sides of the bucket bottom plate 1.

[0020] Furthermore, in order to achieve the desired leveling, soil extraction, and soil disposal effects during operation, it is essential to ensure that when the housing 2, linkage door 3, gravity door 4, suspension rod 5, nut 6, and linkage rod 7 are installed on the bucket bottom plate 1: after the bucket bottom plate 1 rises, the housing 2 is suspended under the bucket bottom plate 1 via the suspension rod 5 and nut 6, and the linkage rod 7 drives the linkage door 3 to open the side of the housing 2; when the bucket bottom plate 1 descends to the top surface of the housing 2, the linkage rod 7 drives the linkage door 3 to close the side of the housing 2; when the bucket bottom plate 1 is laid flat, the gravity door 4 closes the front and rear of the housing 2 under the action of gravity; when the bucket bottom plate 1 swings back and forth, the gravity door 4 swings open.

[0021] To facilitate soil extraction, in this embodiment, preferably: Figure 2 As shown, the two boxes 2 have ramps on the bottom side of the sides below the edge of the bucket.

[0022] To improve service life, in this embodiment, preferably, the housing 2, linkage door 3, gravity door 4, suspension rod 5, linkage rod 7, nut 6, and related hinges are all made of stainless steel.
