Technical Field

[0001] This utility model relates to the field of bucket technology, specifically a leveling device for excavator buckets. Background Technology

[0002] Excavator buckets are important components installed on excavators for digging, loading, unloading, filling, and other tasks. The manufacturing process of buckets includes processes such as material cutting, turning, milling, drilling, forming, welding, grinding, sandblasting, and painting. Buckets are specialized industry equipment accessories and require specialized equipment to operate efficiently and with high quality, such as CNC plasma cutting machines, beveling machines, plate rolling machines, welding positioners, and boring machines.

[0003] In daily use, excavator buckets need to be used to level the soil. When adjusting the bucket angle for leveling, the operator must precisely control the bottom of the bucket to keep it level before pushing it to level the ground. However, the bottom structure of the buckets currently in use has certain limitations in its design, making it difficult to complete the operation efficiently and smoothly when pushing the soil to level. Utility Model Content

[0004] The purpose of this utility model is to provide a leveling device for excavator buckets, which solves the technical problem that the bottom structure of the buckets currently used in the prior art has certain limitations in design, making it difficult to complete the operation efficiently and smoothly when pushing the soil to level. The device achieves the purpose of controlling the scraper to slide vertically down, thereby making it easier for the scraper to level the target soil.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leveling device for an excavator bucket, comprising: a bucket body; a horizontal portion disposed at the bottom of the bucket body; and a leveling portion disposed inside the horizontal portion; wherein the horizontal portion includes: a fixing block fixedly connected to the bottom of the bucket body, the bottom of the fixing block having an installation groove, the interior of the fixing block having a first sliding groove, the bottom of the fixing block having a second sliding groove, the second sliding groove being symmetrically arranged, the second sliding groove being connected to the first sliding groove, and the inner wall of the second sliding groove having a limiting groove, the limiting groove being symmetrically arranged.

[0006] Preferably, a level is slidably connected inside the mounting groove, and a sensor is fixedly connected to the top of the level. A baffle is rotatably connected to the inner wall of the mounting groove, and a slot is provided on the inner wall of the mounting groove. Rotating the baffle covers the mounting groove to prevent dust, debris, or liquid from entering.

[0007] Preferably, a rotating opening is provided on one side of the baffle, and a circular groove is provided at the bottom of the baffle. The circular groove is connected to the rotating opening. A cam is rotatably connected to the inner wall of the rotating opening. The cam is engaged with a slot. A pentagonal rotating block is fixedly connected to the bottom of the cam. The pentagonal rotating block is adapted to the circular groove. The pentagonal rotating block drives the cam to rotate, forming a rigid engagement with the slot. Moreover, the friction coefficient between the cam and the inner wall of the rotating opening is large, providing double protection to prevent loosening.

[0008] Preferably, the leveling part includes: a double-headed telescopic column, fixedly connected to the inner wall of the slide groove; and a sliding block, slidably connected to the inside of the limiting groove.

[0009] Preferably, the telescopic end of the double-headed telescopic column is fixedly connected to a sliding plate, the sliding plate is slidably connected inside the first slide groove, a trapezoidal transmission block is fixedly connected to one side of the sliding plate, a placement groove is opened on one side of the trapezoidal transmission block, a pressure sensor is fixedly connected to the inner wall of the placement groove, and the pressure sensor is adapted to the inner wall of the first slide groove.

The scraper is automatically reset by means of the elastic restoring force of the spring, which reduces the tedious steps of manual operation.

[0012] This utility model provides a leveling device for excavator buckets. It has the following beneficial effects:

[0013] (1) This utility model slides the level and the sensor inside the mounting slot, then rotates the baffle to block the mounting slot, then holds and rotates the pentagonal block to drive the cam to rotate, so that the cam engages with the slot. Because the friction coefficient between the cam and the inner wall of the slot is large, the cam is difficult to rotate, thus achieving the purpose of engaging and fixing the baffle, thereby facilitating the replacement of the level and the sensor.

[0014] (2) This utility model controls the rotation of the bucket body, thereby ensuring that the bottom of the bucket body is accurately and quickly kept level under the action of the horizontal part. Then, it drives the double-headed telescopic column, causing the sliding plate and the trapezoidal transmission block to slide horizontally, thereby causing the trapezoidal transmission block to squeeze the rotating column. Under the limit of the sliding block and the connecting plate, the scraper is controlled to slide vertically down, thereby facilitating the scraper to level the target soil.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example 1:

[0027] Based on the limitations of the bottom structure design of currently used excavator buckets, which makes it difficult to efficiently and smoothly complete the leveling operation, this utility model provides a preferred embodiment of a leveling device for excavator buckets, for example... Figure 1-5 As shown: A leveling device for an excavator bucket includes: a bucket body 1; a horizontal part 2 disposed at the bottom of the bucket body 1; and a leveling part 3 disposed inside the horizontal part 2; wherein, the horizontal part 2 includes: a fixing block 211, which is fixedly connected to the bottom of the bucket body 1, the bottom of the fixing block 211 is provided with an installation groove, the inside of the fixing block 211 is provided with a sliding groove 1, the bottom of the fixing block 211 is provided with a sliding groove 2, the sliding groove 2 is symmetrically arranged, the sliding groove 2 is connected to the sliding groove 1, and the inner wall of the sliding groove 2 is provided with a limiting groove, the limiting grooves being symmetrically arranged.

[0028] A level 212 is slidably connected inside the mounting slot. A sensor 213 is fixedly connected to the top of the level 212. A baffle 214 is rotatably connected to the inner wall of the mounting slot. A slot is provided on the inner wall of the mounting slot.

[0029] A rotating opening is provided on one side of the baffle 214, and a circular groove is provided at the bottom of the baffle 214. The circular groove is connected to the rotating opening. A cam 215 is rotatably connected to the inner wall of the rotating opening. The cam 215 is engaged with the slot. A pentagonal rotating block 216 is fixedly connected to the bottom of the cam 215. The pentagonal rotating block 216 is adapted to the circular groove.

[0030] Furthermore, in this embodiment, the level 212 and the sensing sensor 213 are slidably installed inside the mounting slot. Then, the baffle 214 is rotated to block the mounting slot. The pentagonal rotating block 216 is then held and rotated, causing the pentagonal rotating block 216 to drive the cam 215 to rotate. This causes the cam 215 to engage with the slot. Since the friction coefficient between the cam 215 and the inner wall of the rotating slot is relatively large, the rotation of the cam 215 is difficult, thereby achieving the purpose of engaging and fixing the baffle 214, which facilitates the replacement of the level 212 and the sensing sensor 213.

[0031] Example 2:

[0032] Based on Embodiment 1, a preferred embodiment of the leveling device for an excavator bucket provided by this utility model is, for example... Figure 1-5 As shown: The leveling part 3 includes: a double-headed telescopic column 311, which is fixedly connected to the inner wall of the slide groove 1; and a sliding block 315, which is slidably connected to the inside of the limiting groove.

[0033] The telescopic end of the double-headed telescopic column 311 is fixedly connected to a sliding plate 312. The sliding plate 312 is slidably connected inside the first slide groove. A trapezoidal transmission block 313 is fixedly connected to one side of the sliding plate 312. A placement groove is opened on one side of the trapezoidal transmission block 313. A pressure sensor 314 is fixedly connected to the inner wall of the placement groove. The pressure sensor 314 is adapted to the inner wall of the first slide groove.

[0034] A rotating column 316 is rotatably connected between the inner sides of the sliding block 315. The rotating column 316 is adapted to the trapezoidal transmission block 313. A connecting plate 317 is fixedly connected to the bottom of the sliding block 315. A scraper 318 is fixedly connected to the bottom of the connecting plate 317. The scraper 318 is slidably connected to the slide groove.

[0035] A spring 319 is provided between the connecting plate 317 and the limiting groove. One end of the spring 319 is fixedly connected to the bottom of the connecting plate 317, and the other end of the spring 319 is fixedly connected to the bottom of the inner wall of the limiting groove.

[0036] Furthermore, in this embodiment, by controlling the rotation of the bucket body 1, the bucket body 1 is accurately and quickly kept horizontal at the bottom under the action of the horizontal part 2. Then, the double-headed telescopic column 311 is driven, so that the sliding plate 312 and the trapezoidal transmission block 313 slide horizontally. This causes the trapezoidal transmission block 313 to squeeze the rotating column 316. Under the limitation of the sliding block 315 and the connecting plate 317, the scraper 318 is controlled to slide vertically down, so as to facilitate the scraper 318 to level the target soil. Conversely, when the trapezoidal transmission block 313 stops squeezing the rotating column 316, the scraper 318 is controlled to slide back to its original position under the action of the spring 319.

[0037] In use, firstly, the level 212 and the sensor 213 are slidably installed inside the mounting slot. Then, the baffle 214 is rotated to cover the mounting slot. Next, the pentagonal rotating block 216 is held and rotated, causing the pentagonal rotating block 216 to drive the cam 215 to rotate, thereby engaging the cam 215 with the slot. Due to the high coefficient of friction between the cam 215 and the inner wall of the rotating opening, the rotation of the cam 215 is difficult, thus achieving the purpose of engaging and fixing the baffle 214, which facilitates the replacement of the level 212 and the sensor 213. Secondly, the bucket is controlled. The main body 1 rotates, thereby ensuring that the bottom of the bucket body 1 remains level accurately and quickly under the action of the horizontal part 2. Then, the double-headed telescopic column 311 is driven, causing the sliding plate 312 and the trapezoidal transmission block 313 to slide horizontally. This causes the trapezoidal transmission block 313 to press against the rotating column 316. Under the limitation of the sliding block 315 and the connecting plate 317, the scraper 318 is controlled to slide down vertically, thus facilitating the scraper 318 to level the target soil. Conversely, when the trapezoidal transmission block 313 stops pressing against the rotating column 316, the scraper 318 is controlled to slide back to its original position under the action of the spring 319.
