Description

Technical Field

[0001] This invention relates to the field of tools for cleaning attachments to shovel buckets, specifically a loader bucket cleaning device. Background Technology

[0002] Loaders are earthmoving machines widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. They are mainly used to shovel, load, unload, and transport bulk materials such as soil and stone. When loaders use their buckets to transfer materials, sticky substances often accumulate on the inner walls of the bucket, which reduces work efficiency for subsequent material transfers.

[0003] According to Chinese Patent No. CN222842750U, a cleaning structure for a small tracked bulldozer bucket is disclosed. This utility model uses a flushing module to flush the inner wall of the bucket in all directions, thereby improving the cleaning effect of the bucket and making the cleaning effect of the bucket better.

[0004] The above-mentioned technical solution uses water spraying to wash the inside of the bucket and a rotating scraper roller to scrape off the inner wall of the bucket. However, this method cannot efficiently remove clay that covers a large area and is too tightly stuck. Therefore, we propose a loader bucket cleaning device. Summary of the Invention

[0018] The fixed arms at both ends of the crossbar are movably connected to the short rotating shaft, and the fixed arms on both sides of the middle of the crossbar are movably connected to the long rotating shaft. The ends of the short and long rotating shafts that extend out of the fixed arms are connected to the sprockets at one end of the chain drive device.

[0019] Preferably, a short crossbeam is also vertically fixed on the fixed arms distributed at both ends of the crossbar, and a short corrugated plate is fixed on one side of the short crossbeam;

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-4 The present invention provides a technical solution: a loader bucket cleaning device, including a tilting arm 1 movably installed on the outer top surface of the bucket and a lifting ring 102 rotating on the tilting arm 1. A power motor 101 for driving the tilting arm 1 to rotate is also installed on the outer top surface of the bucket. A telescopically adjustable hydraulic rod 103 is connected between the tilting arm 1 and the lifting ring 102, and a rotating debris removal component for cleaning the inner wall of the bucket is provided at the end of the lifting ring 102 away from the tilting arm 1.

[0045] In this embodiment, by starting the power motor 101 to rotate forward, the tilting arm 1 drives the rotating cleaning component to extend into the inside of the bucket, and the rotating cleaning component cleans the inner wall of the bucket. Conversely, by starting the power motor 101 to rotate backward, the tilting arm 1 drives the rotating cleaning component to exit the bucket and move to the outer top position of the bucket, so that the cleaning device will not obstruct the loader's bucket from scooping up the material to be transferred. Furthermore, by pushing and pulling the lifting ring 102 through the hydraulic rod 103 on one side of the tilting arm 1, the lifting ring 102 can drive the rotating cleaning component to rotate, making it convenient for the rotating cleaning component to be aligned with the position inside the bucket that needs to be cleaned.

[0046] Please see Figures 1-4 The rotating debris removal assembly for cleaning the inner wall of the bucket includes a crossbar 2 connected to the middle of the lifting ring 102 via a bearing. The lifting ring 102 is provided with an assist mechanism that drives the crossbar 2 to rotate. A scraper 201 is fixed on the circumferential side of the crossbar 2, and drive assemblies 3 are distributed on both ends and the middle sides of the crossbar 2.

[0047] The assist mechanism that drives the crossbar 2 to rotate includes a motor 102a mounted on the surface of the lifting ring 102 away from the hydraulic rod 103. The output end of the motor 102a drives the crossbar 2 to rotate through a chain drive device 102b.

[0048] In this embodiment, the motor 102a of the assist mechanism drives the chain drive device 102b to rotate, so that the chain drive device 102b can drive the crossbar 2 to rotate. At this time, the crossbar 2 will drive the scraper 201 and the drive components 3 distributed on both ends and the middle of the crossbar 2 to rotate, so that the scraper 201 can scrape off the attached material on the inner wall of the bucket, and the drive components 3 will rotate together with the crossbar 2.

[0049] It should be noted that, in order to improve the efficiency of cleaning the sticky deposits on the inner wall of the bucket, a spray washing assembly can be installed on the bucket of the loader. The water supply can be pressurized by the loader to make the spray washing assembly aim at the inner side of the bucket. The rotating debris removal assembly can be used in conjunction with the spray washing assembly to improve the cleaning effect on the bucket.

[0050] Please see Figures 1-8 The two sides of the lifting ring 102 away from the flipping arm 1 are fixed with toothed rings 102c that pass through the crossbar 2. The two ends and the two sides of the middle of the crossbar 2 are provided with protrusions.

[0051] The drive assembly 3 includes a gear shaft 301 inserted in the protrusion, one end of the gear shaft 301 meshing with the gear ring 102c, and a bracket 302 fixed on the side of the protrusion away from the gear ring 102c. The bracket 302 is composed of a fixing frame perpendicular to the gear shaft 301 and a sector plate, and the surface of the sector plate is provided with an arc groove.

[0052] The drive assembly 3 includes a short rotating shaft 308 and a long rotating shaft 308c distributed at both ends and the middle sides of the crossbar 2, and the arc groove of the fan-shaped plate is slidably connected to one end of the fixed arm 304. A long tension spring 307 is connected between one end of the fixed arm 304 and the fixed frame of the bracket 302.

[0053] One end of the gear shaft 301 away from the gear ring 102c is connected to the fixed frame side of the bracket 302 and is connected to a chain drive device 2 303. The two ends of the fixed arm 304 away from the long tension spring 307 are connected to chain drive devices 305. The two adjacent sprockets of chain drive devices 2 303 and chain drive devices 305 are connected to a toothed disc assembly 306. Chain drive device 2 303 drives chain drive device 305 to reverse through the toothed disc assembly 306. The sprocket of chain drive device 2 303 near the fan-shaped plate is coaxial with the arc groove.

[0054] The fixed arms 304 located at both ends of the crossbar 2 are movably connected to the short rotating shaft 308, and the fixed arms 304 located on both sides of the middle of the crossbar 2 are movably connected to the long rotating shaft 308c. The ends of the short rotating shaft 308 and the long rotating shaft 308c extending out of the fixed arms 304 are connected to the sprocket at one end of the chain drive device 305.

[0055] In this embodiment, when the crossbar 2 drives the gear shaft 301 to rotate, one end of the gear shaft 301 will mesh with the gear ring 102c on the side of the lifting ring 102. Thus, when the crossbar 2 rotates, the gear shaft 301 can drive the chain drive device 2 303 to rotate faster. Since the chain drive device 2 303 and the chain drive device 305 are driven by the gear disk group 306, the chain drive device 2 303 can drive the chain drive device 305 to rotate in reverse. At this time, the drive components 3 distributed at both ends and the middle sides of the crossbar 2 will drive the short shaft 308 and the long shaft 308c to rotate through the chain drive device 305.

[0056] When the crossbar 2 stops rotating, the long tension spring 307 will pull the bracket 302 and the fixed arm 304 to retract and fold. When the crossbar 2 drives the scraper 201 and the drive assembly 3 to rotate, the drive assembly 3 generates centrifugal force through rotation, which will cause one end of the fixed arm 304 to rotate along the fan-shaped plate of the bracket 302. At this time, the long tension spring 307 between the fixed arm 304 and the bracket 302 will be stretched.

[0057] Specifically, the rotation angle of the fixed arm 304 is limited by the arc groove angle of the sector plate. At the same time, when the fixed arm 304 drives the chain drive device 305 to rotate, the toothed disc assembly 306 will continuously cause the chain drive device 2 303 to drive the chain drive device 305 to rotate.

[0058] It should be noted that by changing the tooth ratio of the gear set 306, the operating speed between the chain drive device 2 303 and the chain drive device 305 can be adjusted, and thus the rotation speed of the short shaft 308 and the long shaft 308c can be adjusted as needed.

[0059] Please see Figure 1 and Figures 5-8 A short crossbeam 304a is also vertically fixed on the fixed arms 304 distributed at both ends of the crossbar 2, and a short corrugated plate 304b is fixed on one side of the short crossbeam 304a.

[0060] A long crossbeam 304c is vertically fixed on the fixed arms 304 distributed on both sides of the middle of the crossbar 2, and a long corrugated plate 304d is symmetrically fixed on one side of the long crossbeam 304c.

[0061] A short reciprocating screw portion 308b is formed on the side of the short rotating shaft 308 near the short corrugated plate 304b, and a long reciprocating screw portion 308d is formed on the side of the long rotating shaft 308c near the long corrugated plate 304d. A dividing mechanism 7 is provided on the short rotating shaft 308 and the long rotating shaft 308c to prevent the attachment from sticking to the inner wall of the bucket by cross-dividing the attachment.

[0062] The dividing mechanism 7 includes a slider 701 threadedly connected to a short reciprocating screw section 308b and a long reciprocating screw section 308d; a longitudinal cutting bar 702 is slidably connected to the upper part of the slider 701, and a transverse cutting bar 703 is slidably connected to the horizontal side of the slider 701; a roller is connected to one side of both the longitudinal cutting bar 702 and the transverse cutting bar 703, and the longitudinal cutting bar 702 and the transverse cutting bar 703 are staggered and parallel; one side of the slider 701 is connected to the short crossbeam 304a and the long crossbeam 308d respectively. The planes of 04c are in contact. Since the dividing mechanisms 7 distributed at both ends and the middle sides of the crossbar 2 will drive the longitudinal cutting strips 702 and transverse cutting strips 703 on the slider 701 to slide along the short wave plate 304b and the long wave plate 304d respectively, the longitudinal cutting strips 702 and transverse cutting strips 703 cooperate with the slider 701 to prevent the slider 701 from rotating due to reciprocating transverse movement on the short reciprocating lead screw part 308b and the long reciprocating lead screw part 308d.

[0063] The longitudinal cutting strip 702 and the transverse cutting strip 703 located on the short crossbeam 304a roll against the two sides of the short corrugated plate 304b via rollers at one end, and the longitudinal cutting strip 702 and the transverse cutting strip 703 located on the long crossbeam 304c roll against the two sides of the long corrugated plate 304d via rollers at one end.

[0064] Please see Figure 6 and Figure 8 Both the longitudinal cutting bar 702 and the transverse cutting bar 703 have strip-shaped openings on their surfaces. A guide pin is installed on the slider 701, which passes through the strip-shaped opening. The guide pin is used to prevent the longitudinal cutting bar 702 and the transverse cutting bar 703 from sliding off-center. A compression spring is connected between one end of the strip-shaped opening of the longitudinal cutting bar 702 and the guide pin, and a tightening spring is connected between one end of the strip-shaped opening of the transverse cutting bar 703 and the guide pin.

[0065] In this embodiment, when the short rotating shaft 308 rotates, the short reciprocating screw 308b on the short rotating shaft 308 will drive the slider 701 to move laterally for a short distance. At this time, the slider 701 can drive the longitudinal cutting bar 702 and the transverse cutting bar 703 to move laterally back and forth. The rollers at one end of the longitudinal cutting bar 702 and the transverse cutting bar 703 roll and abut against both sides of the short wave plate 304b. Under the action of the compression spring, the longitudinal cutting bar 702 can slide back and forth on the slider 701. The movement, under the action of the tightening spring, allows the transverse cutting bar 703 to slide back and forth on the horizontal side of the slider 701, so that the staggered longitudinal cutting bar 702 and transverse cutting bar 703 can alternately extend and retract when moving laterally in sync, ensuring that the longitudinal cutting bar 702 and transverse cutting bar 703 at both ends of the crossbar 2 can cross-segment the adhesive on both sides of the inner wall of the bucket, so that the adhesive on both sides of the inner wall of the bucket is separated from the adhesive in the middle of the inner wall of the bucket;

[0066] When the long rotating shaft 308c rotates, the long reciprocating screw part 308d on the long rotating shaft 308c will drive the slider 701 to make a short-distance lateral reciprocating movement, so that the longitudinal cutting bar 702 and the transverse cutting bar 703 on both sides of the middle of the cross bar 2 can cross-cut the adhesive attachments in the middle of the inner wall of the bucket.

[0067] Therefore, the dividing mechanism 7 distributed at both ends and the middle sides of the crossbar 2 can separate the adhesive residue on the inner wall of the bucket into small, dispersed pieces, thus avoiding large areas of adhesive residue covering the inner wall of the bucket and causing difficulties in mud removal.

[0068] Please see Figure 2 , Figure 5 and Figure 6 The short rotating shaft 308 extends through the chain drive device 305 and is fixed to one end of a lever turntable 308a for scraping off the attached material at the corner of the inner wall of the bucket.

[0069] In this embodiment, when the chain drive device 305 drives the short rotating shaft 308 to rotate inside the bucket, the short rotating shaft 308 will drive the lever turntable 308a to intermittently scrape the corner of the inner side of the bucket and the inner arc surface, thereby loosening the attached material at the corner of the inner wall of the bucket and rotating and throwing out the attached material.

[0070] Please see Figure 1 , Figure 2 and Figures 5-11 The short shaft 308 and the long shaft 308c are also provided with a deflecting and rolling assembly 4 for rolling the attached material. The rolling assembly 4 for deflecting and rolling the attached material includes a ball seat 401 fixed on the short shaft 308 and the long shaft 308c. The outer side of the ball seat 401 is movably connected to the elliptical sleeve 402 through two coaxial cylindrical blocks. Rolling wheels 403 are fixed on both sides of the sleeve 402. The outer edge of the rolling wheel 403 is provided with rolling teeth to poke indentations into the attached material.

[0071] Between the two rolling rollers 403, there is a shovel plate 403b that scrapes away the sticky material by centrifugal swinging. A short tension spring 403a is connected between the sleeve 402 and the shovel plate 403b to tighten the position of the shovel plate 403b.

[0072] In this embodiment, when the short shaft 308 and the long shaft 308c rotate, they drive the sleeve 402 and the rolling wheel 403 through the ball seat 401 to roll the attached material on the inner wall of the bucket. The rolling wheel 403 also pokes the attached material with the hobbing teeth on its outer edge, thereby loosening the surface of the attached material. At the same time, when the rolling wheel 403 rotates, it drives the shovel plate 403b to swing centrifugally. Thus, after overcoming the tension of the short tension spring 403a, the shovel plate 403b can scoop up the attached material and remove it from the inner wall of the bucket.

[0073] Please see Figures 8-11The short crossbeam 304a and the long crossbeam 304c are also equipped with guide plates 5 and mounting seats 6 distributed on both sides of the rolling roller 403. One end of the guide plate 5 is connected to the guide wheel, and a limit seat 8 is provided on one side of the mounting seat 6. An anti-loosening spring 9 is fixed between the mounting seat 6 and the limit seat 8.

[0074] A compression ring 404 is fixed on the side of the rolling roller 403 near the guide plate 5, and the side of the compression ring 404 is provided with not less than two protrusions.

[0075] In this embodiment, when the rolling roller 403 rotates, the protrusion on the side of the extrusion ring 404 will intermittently extrude into the guide wheel at one end of the guide plate 5, so that the sleeve 402 between the rolling rollers 403 will deflect around the ball seat 401. When the rolling roller 403 deflects, it will extrude into the limiting seat 8, so that the limiting seat 8 will compress the anti-loosening spring 9.

[0076] When the protrusion on the side of the compression ring 404 disengages from the guide wheel at one end of the guide plate 5, the anti-loosening spring 9 resets and pushes the limit seat 8 to press against the side of the rolling roller 403, so that the rolling roller 403 can reset. The rolling roller 403, which can deflect and reset, can deflect and compress the dented attachment, so that the attachment on the inner wall of the bucket can be separated laterally, thereby accelerating the loosening between the attachment and the inner wall of the bucket.

[0077] The working principle is as follows: the tilting arm 1 drives the rotating debris removal component to extend into the inside of the bucket. The rotating crossbar 2 drives the drive component 3 to drive the dividing mechanism 7 to cross-cut the adhesive residue on the inner wall of the bucket. At the same time, the rolling component 4 is used to loosen and scoop up the adhesive residue on the inner wall of the bucket. Finally, the rotating scraper 201 can be used to scrape and clean the loose residue. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0078] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
