Description

Technical Field

[0001] The utility model belongs to the technical field of excavator buckets, and in particular relates to a controllable excavator bucket. Background Art

[0002] In the prior art, the site leveling during the civil construction process requires the excavator to continuously dig and level the soil. Digging requires the excavator to carry a toothed bucket, and leveling requires the excavator to carry a paving bucket. During the site leveling construction process, the excavator needs to switch back and forth between a toothed bucket and a flat bucket to achieve the site leveling and backfilling requirements of the construction site. The bucket is changed from a toothed bucket to a flat bucket mostly by welding or replacing the bucket. Both conversion forms require the excavator to stop working. The replacement process needs to be manually replaced, which has high requirements for operators and high risks during the replacement process. In addition, the bucket cannot be switched at any time according to the working conditions, resulting in a time-consuming and labor-intensive replacement process, low construction efficiency and high construction costs.

[0003] The Chinese utility model patent with announcement number CN220486582U discloses an excavator bucket with a scraper. The telescopic rod is turned on by a switch, and the telescopic rod will drive the mounting plate and the scraper to move forward, so that the front end of the scraper extends out of the bucket teeth, and the scraper can be used for scraping. When the scraper moves, the insertion rod will move along the slide groove, so that the scraper only moves radially. When it is used or not in use, the scraper can be collected by the telescopic rod. Although this bucket solves the technical problem that the bucket teeth and the scraper cannot be switched at any time, a large amount of soil will accumulate on the insertion rod when the scraper is used for scraping. As a result, the telescopic rod cannot completely collect the scraper when the scraper is used or not in use. At this time, manual intervention is required, resulting in reduced construction efficiency.

[0004] An excavator bucket is needed to solve the above technical problems. Summary of the invention

[0005] The utility model aims to provide a controllable excavator bucket, which is used to solve the technical problem that the tooth bucket and the flat bucket in the prior art cannot be switched at any time, resulting in low construction efficiency.

[0006] The technical solution of the utility model to solve the technical problem is:

[0007] A controllable excavator bucket comprises a bucket body, wherein the front end of the bucket body is provided with fixed teeth; the front end of the bucket body is also provided with a main shaft which can move left and right; the main shaft is provided with movable teeth, and the length of the main shaft is greater than the length of the front end of the bucket body; driving devices for driving the main shaft to move are symmetrically arranged on both sides of the bucket body, and when the driving device drives the main shaft to move left and right, the movable teeth on the main shaft are moved to the bottom of the adjacent fixed teeth to be hidden to form a tooth bucket, or the movable teeth on the main shaft are moved to the gap beside the upper fixed teeth to form a flat bucket.

[0008] Preferably, the driving device includes a hydraulic cylinder, an actuating rod, and an actuating ring; one end of the hydraulic cylinder is fixed to the bucket body, and the other end is connected to the actuating rod on the same side; an actuating ring is provided at one end of the actuating rod close to the fixed tooth, and the actuating ring is passed through both ends of the main shaft.

[0009] Preferably, it also includes an intelligent force measuring device, which is arranged on the actuating rod.

[0010] Preferably, it also includes a limiting ring, and the limiting rings are respectively arranged on both sides of the actuating ring on the main shaft.

[0011] Preferably, the actuating rod and the actuating ring are connected by welding.

[0012] Preferably, the actuating rod and the actuating ring are integrally formed.

[0013] The beneficial effects of the utility model are as follows: by setting the movable teeth, the driving device, and the main shaft, when it is necessary to switch between the tooth bucket and the flat bucket, the driving device drives the main shaft to move left and right, so that the movable teeth on the main shaft move to the bottom of the adjacent fixed teeth to hide and form a tooth bucket, or the movable teeth on the main shaft move to the gap beside the upper fixed teeth to form a flat bucket. This device eliminates the need for manual participation in the switching process between the tooth bucket and the flat bucket, and does not require manual welding of the flat bucket. In addition, the movable teeth are welded to the main shaft, so the movement of the movable teeth only depends on the left and right movement of the main shaft, and the accumulated soil during the construction process does not affect the movement of the movable teeth, thereby making the construction efficiency of the excavator high and the construction cost low.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, a controllable excavator bucket disclosed in the utility model comprises a bucket body, wherein the front end of the bucket body is provided with fixed teeth 1 and a main shaft 5 which can be moved left and right; the main shaft 5 is provided with movable teeth 6, and preferably, the movable teeth 6 are welded on the main shaft 5; the length of the main shaft 5 is greater than the length of the front end of the bucket body; driving devices for driving the movement of the main shaft are symmetrically arranged on both sides of the bucket body, and the driving devices include a hydraulic cylinder 2, an actuating rod 3, and an actuating ring 4; one end of the hydraulic cylinder 2 is fixed to the bucket body, and the other end is connected to the actuating rod 3 on the same side, and an intelligent force measuring device 8 is provided on the actuating rod 3, and the intelligent force measuring device 8 monitors the force conditions of the movable teeth and fixed teeth of the excavator in real time, and when the force on the fixed teeth 1 and the movable teeth 6 of the excavator is too large or When subjected to abnormal force, the intelligent force measuring device 8 issues an alarm to remind relevant staff to check. The intelligent force measuring device 8 belongs to the prior art and is therefore not described in detail here. An actuating ring 4 is arranged at one end of the actuating rod 3 close to the fixed teeth, and the actuating ring 4 is passed through the two ends of the main shaft 5. The actuating rod 3 and the actuating ring 4 are connected by welding or formed as one piece. The limit rings 7 are respectively passed through the two sides of the actuating ring on the main shaft 5. The limit rings 7 can ensure the movement angle of the main shaft 5 to prevent the movement angle from being too large and failing to achieve the effect of a flat bucket. When the driving device drives the main shaft to move left and right, the movable teeth on the main shaft are moved to the bottom of the adjacent fixed teeth to hide and form a tooth bucket, or the movable teeth on the main shaft are moved to the gap next to the upper fixed teeth to form a flat bucket.

[0019] The specific switching process between tooth bucket and flat bucket is as follows:

[0020] When the excavator is working, if it is necessary to change the tooth bucket into a flat bucket for leveling operations, press the conversion button. At this time, the hydraulic cylinder acts to push the actuating rod and the actuating ring to move. The actuating rod and the actuating ring move so that the main shaft can move to the left, and the movable teeth welded on the main shaft move to the gap next to the upper fixed teeth, so that the fixed teeth and movable teeth of the excavator form a new flat bucket; when it is necessary to change the flat bucket into a tooth bucket for digging operations, press the conversion button again. At this time, the hydraulic cylinder acts to push the actuating rod and the actuating ring to move. The actuating rod and the actuating ring move so that the main shaft can move to the right, and the movable teeth welded on the main shaft move to the bottom of the adjacent fixed teeth and hide, so that the fixed teeth and movable teeth of the excavator form a new tooth bucket.

[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
