Description

Technical Field

[0001] The present application relates to the field of earthwork construction, and in particular to a one-time forming machine for excavating an earthwork trench. Background Art

[0002] At present, with the rapid development of urban construction, earthwork construction mostly uses mechanical equipment instead of manpower to dig trenches, uses machinery to quickly construct earthwork, improves construction efficiency, and speeds up construction progress.

[0003] Existing trench construction machinery mostly uses excavators to excavate earth. Since the construction requirements of some trenches are relatively high, the bottom of the trench needs to be flat. In order to facilitate the excavation of earth, the excavator's bucket is mostly equipped with hook teeth. When the hook teeth are leveling the bottom of the trench, the setting of the hook teeth will leave tooth marks on the bottom of the trench. Therefore, manual cooperation with the machine is required to level the tooth marks on the bottom of the trench at any time during the mechanical excavation process.

[0004] The above-mentioned prior art solutions have the following defects: manual leveling of tooth marks results in high labor intensity for workers during trench excavation. Utility Model Content

[0005] In order to reduce the labor intensity of workers, the present application provides a one-time forming machine for excavating earth trenches.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A one-step forming machine for excavating earth trenches comprises a hook bucket and a scraper. The hook bucket is provided with hook teeth, the hook teeth are fixedly connected to the hook bucket, the scraper abuts against the hook teeth, the scraper abuts against the bottom surface of the trench when used to clean the bottom of the trench, and a connecting device is provided between the scraper and the hook bucket, the connecting device is used to fix the scraper in the hook bucket.

[0008] By adopting the above scheme, when using the forming machine, first use the connecting device to fix the scraper in the hook bucket so that the scraper abuts against the hook teeth. Then, when the hook bucket is used to clean the bottom of the groove, the scraper abuts against the bottom wall of the groove. Since the scraper is a plane, the scraper directly scrapes the bottom of the groove into a plane, thereby eliminating the need to manually clean the tooth marks of the hook teeth, thereby achieving the purpose of reducing the labor intensity of workers.

[0009] Furthermore, the connecting device includes a connecting plate and a connecting block, the connecting plate is fixedly connected to the scraper, the connecting block is fixedly connected to the connecting plate, a connecting groove is provided at the side wall of the connecting block corresponding to the hook bucket, the side wall of the hook bucket is plugged into the connecting groove, and the connecting block is fixedly connected to the side wall of the hook bucket.

[0010] By adopting the above scheme, when using the connecting device, first move the connecting plate to drive the connecting block close to the side wall of the hook bucket, so that the connecting groove on the connecting block is plugged into the side wall of the hook bucket, and then fix the connecting block to the side wall of the hook bucket. Since the scraper is fixedly connected to the connecting plate, the connecting plate drives the scraper to be fixed to the hook bucket, thereby setting the scraper at the hook teeth.

[0011] Furthermore, a reinforcing rib is provided between the connecting plate and the connecting block, and two ends of the reinforcing rib are fixedly connected to the connecting plate and the connecting block respectively.

[0012] By adopting the above solution, the two ends of the reinforcing rib are respectively fixedly connected to the connecting plate and the connecting block, so that the reinforcing rib increases the stability of the connecting block after being connected to the connecting plate.

[0013] Furthermore, the connecting plate includes a first plate and a second plate, the first plate is fixedly connected to the scraper plate, the second plate is fixedly connected to the connecting block, and a telescopic device is provided between the first plate and the second plate, and the telescopic device is used to adjust the length of the connecting plate.

[0014] By adopting the above scheme, the connecting plate is divided into a first plate and a second plate, and a telescopic device is provided between the first plate and the second plate to adjust the positions of the first plate and the second plate, thereby adjusting the length of the connecting plate. After the length of the connecting plate is adjusted, the connecting block is connected and fixed to the side wall of the bucket, so that the connecting plate is suitable for buckets of different specifications and models, thereby improving the convenience of installing the connecting block.

[0015] Furthermore, the telescopic device comprises a telescopic slot and a telescopic plate. The telescopic slot is arranged on a side of the second plate away from the scraper plate. The telescopic plate is fixedly connected to the first plate, and the telescopic plate is plugged into and matched with the telescopic slot.

[0016] By adopting the above scheme, when using the telescopic device, first pull the second plate to drive the connecting block close to the side wall of the bucket, and the second plate drives the telescopic plate to slide in the telescopic groove. The telescopic plate is used to ensure that the first plate and the second plate are always in a connected state, so that after the connecting block is fixed to the side wall of the bucket, the scraper is driven to be fixedly connected to the bucket teeth.

[0017] Furthermore, the telescopic plate is provided with an anti-slip device, which includes an anti-slip groove, an anti-slip block and a limiting block. The anti-slip groove is provided with a side wall of the telescopic groove, the anti-slip block is fixedly connected to the telescopic plate, the anti-slip block is located in the anti-slip groove, the anti-slip block is slidably connected to the anti-slip groove, the limiting block is arranged at the notch of the anti-slip groove, and the limiting block is fixedly connected to the anti-slip groove.

[0018] By adopting the above scheme, when the telescopic plate slides in the telescopic slot, the telescopic plate drives the anti-slip block to slide in the anti-slip slot. When the telescopic plate slides to the point of being separated from the telescopic slot, the telescopic plate drives the anti-slip block to abut against the limit block. The limit block prevents the anti-slip block from continuing to slide, thereby preventing the telescopic plate from slipping out of the telescopic slot.

[0019] Furthermore, the scraper is provided with a tooth guard bar, which is fixedly connected to the scraper, and a plug-in groove is provided on the tooth guard bar, and the plug-in groove is correspondingly arranged with the hook tooth, and the hook tooth is plugged and matched with the plug-in groove.

At the same time, the tooth guard bar also prevents the hook tooth from contacting with earth and stone, thereby further reducing the possibility of tooth marks on the bottom of the groove.

[0021] Furthermore, a locking bolt is provided on the side of the tooth guard bar away from the scraper, the locking bolt is threadedly connected to the tooth guard bar, and the locking bolt passes through the side wall of the plug-in slot and abuts against the hook tooth.

[0022] By adopting the above scheme, after the tooth guard bar is sleeved on the outside of the hook tooth, the locking bolt is rotated to make the locking bolt abut against the hook tooth, thereby fixing the hook tooth and the tooth guard bar, thereby improving the stability of the tooth guard bar and the hook tooth after being fixed.

[0023] Furthermore, a side of the scraper away from the hook teeth is configured as a blade-shaped structure.

[0024] By adopting the above solution, the scraper is set to a blade type, which makes it easier for the scraper to scrape the bottom of the trench, thereby improving the convenience during trench excavation.

[0025] In summary, this application has the following technical effects:

[0026] By setting a scraper, when using the forming machine, first use the connection device to fix the scraper in the hook bucket so that the scraper abuts against the hook teeth. Then, when the hook bucket is used to clean the bottom of the groove, the scraper abuts against the bottom wall of the groove. Since the scraper is a plane, the scraper directly scrapes the bottom of the groove into a plane, so there is no need to manually clean the tooth marks of the hook teeth, thereby achieving the purpose of reducing the labor intensity of workers.

[0027] By setting the first plate and the second plate, the connecting plate is divided into the first plate and the second plate, and a telescopic device is set between the first plate and the second plate to adjust the positions of the first plate and the second plate, so as to adjust the length of the connecting plate. After the length of the connecting plate is adjusted, the connecting block is connected and fixed to the side wall of the bucket, so that the connecting plate is suitable for buckets of different specifications and models, and the convenience of installing the connecting block is improved;

[0028] By providing a tooth guard bar, the insertion groove on the tooth guard bar is plugged into the hook tooth, so that the tooth guard bar protects the hook tooth. At the same time, the tooth guard bar also prevents the hook tooth from contacting with earth and stone, thereby further reducing the possibility of tooth marks on the bottom of the groove.
