Description

Technical Field

[0001] The utility model relates to the field of ore mining, in particular to a cleaning device for a bucket of a loader. Background Art

[0002] A loader is a self-propelled earth-moving machine that can perform shoveling, loading, transporting and unloading operations. A loader is mainly composed of three parts: an engine, a chassis including a traveling mechanism, and a working device. It has the advantages of fast operating speed, high efficiency, good maneuverability, and easy operation. It is widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. By replacing different auxiliary working devices, it can also perform bulldozing, lifting, and loading and unloading of other materials such as wood. The working device includes a bucket, which is used to excavate and move earth and rocks.

[0003] During long-term operation, a lot of mud will accumulate in the bucket. The mud will condense into lumps, which will aggravate the mud adhesion, increase the weight of the bucket and affect the production operation. After drying, the condensed mud will firmly adhere to the inner wall of the bucket, which is not convenient to clean and remove. At the same time, due to the unique arc structure inside the bucket, it is difficult for personnel to carry out a more comprehensive cleaning in a short time with a handheld shovel when cleaning. In view of the existing problems, a cleaning device for a loader bucket is proposed. Utility Model Content

[0004] The utility model aims to solve the disadvantage in the prior art that it is inconvenient for personnel to clean the bucket due to the special arc structure inside the bucket, and proposes a cleaning device for the bucket of a loader.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1

[0022] Reference Figure 1-4 A cleaning device for a bucket of a loader includes two support frames 1 and a cleaning mechanism 3. The two support frames 1 are symmetrically spaced, and movable slides 2 are fixedly mounted on the two support frames 1. By fixing the two support frames 1 at both ends and corresponding to the shape of the inner side of the bucket, the bucket can be stably placed inside the bucket when cleaning it without external force limit fixation, and the movable slide 2 is responsible for guiding the screw rod 31 and the rotating rod 33 to move up and down along the inner wall of the bucket. The cleaning mechanism 3 includes a screw rod 31 and a rotating rod 33. Both ends of the screw rod 31 and the rotating rod 33 are on the movable slide 2. The screw 31 is threadedly connected with a removal component 32, which includes a threaded sleeve and two rotating parts 321. The two rotating parts 321 expand the cleaning range and make the cleaning more efficient. The threaded sleeve is threadedly connected to the screw 31. The two rotating parts 321 are arranged at intervals and the rotating sleeve is arranged on the threaded sleeve. The threaded sleeve is threadedly connected to the screw 31, and the lateral movement of the rotating part 321 can be achieved by rotating the screw 31. A scraper 322 is fixedly installed in a circular array on the outer circular wall of the rotating part 321. The scraper 322 can remove the mud accumulated on the inner wall of the bucket.

[0023] A limited slide bar is fixedly installed on the outer circumferential array of the rotating rod 33, and a transmission gear 34 is provided on the sliding sleeve of the outer side of the rotating rod 33. The transmission gear 34 is provided with a slide groove corresponding to the limited slide bar. The cooperation of the slide groove and the limited slide bar can, on the one hand, drive the transmission gear 34 to rotate through the rotation of the rotating rod 33, thereby driving the two rotating parts 321 to rotate. On the other hand, it can also cooperate to realize the left and right movement of the transmission gear 34 and the two rotating parts 321. A transmission gear ring 35 is fixedly installed between the two rotating parts 321. The transmission gear ring 35 is sleeved on the outer side of the screw rod 31 at intervals. The transmission gear 34 is meshed and connected with the transmission gear ring 35 for transmission, so that the two rotating parts 321 can be driven to rotate.

[0024] Brush plates 323 are fixedly mounted in a circumferential array on the outer circular wall of the rotating member 321. The brush plates 323 and the scrapers 322 are arranged alternately to remove the sand and dust on the inner wall of the bucket.

[0025] By sliding both ends of the screw rod 31 and the rotating rod 33 in the movable slide 2, the two rotating parts 321 can move up and down along the inner wall of the bucket, and the two rotating parts 321 rely on the scraper 322 and the brush plate 323 to remove mud and rocks on the inner wall of the bucket, so that the cleaning of the inner wall of the bucket is more comprehensive and the cleaning effect is optimized.

[0026] A first motor 36 is fixedly installed on the limit plate 38 corresponding to the screw 31, and the output shaft of the first motor 36 is fixedly connected to the screw 31. A second motor 37 is fixedly installed on the limit plate 38 corresponding to the rotating rod 33, and the output shaft of the second motor 37 is fixedly connected to the rotating rod 33. Both the first motor 36 and the second motor 37 are servo motors. When the removal component 32 needs to move left and right, the second motor 37 suppresses the rotation of the rotating rod 33, thereby ensuring the left and right movement of the removal component 32 when the screw 31 rotates.

[0027] Example 2

[0028] According to Example 1, the up and down movement of the screw rod 31, the rotating rod 33 and the removal assembly 32 in Example 1 is not easy to control. Figure 1-4 , as another preferred embodiment of the utility model, based on embodiment 1;

[0029] The adjusting mechanism 4 also includes a telescopic rod 42 and a fixed frame 43. The fixed frame 43 is fixedly mounted on the supporting frame 1. The telescopic rod 42 is rotatably mounted on the upper end of the fixed frame 43. A connecting plate 41 is fixedly mounted on the telescopic end of the telescopic rod 42. The telescopic rod 42 is a hydraulic telescopic rod. The connecting plate 41 is rotatably sleeved on both ends of the rotating rod 33. The screw rod 31 and both ends of the rotating rod 33 are rotatably sleeved with limit plates 38. Through the extension and retraction of the telescopic rod 42 in the adjusting mechanism 4 and the support and limitation of the limit plate 38, the screw rod 31 and both ends of the rotating rod 33 can be synchronously driven to slide up and down in the movable slide 2, so that there is no need for personnel to push up and down, which saves time and effort. At the same time, it is convenient to gradually control the removal of components up and down, so that the cleaning effect is better and the cleaning dead angle is reduced.

[0030] Working principle: by fixing the two support frames 1 at both ends and setting them corresponding to the shape of the inner side of the bucket, the bucket can be stably placed inside the bucket when cleaning, without the need for external force to limit and fix it, turning on the second motor 37 to drive the rotating rod 33 to rotate, and the transmission gear 34 is meshed with the transmission gear ring 35 to drive the two rotating parts 321 to rotate, and the mud and rocks on the inner wall of the bucket are removed by the scraper 322 and the brush plate 323. When it is necessary to move left and right, turn on the first motor 36 to drive the screw 31 to rotate. At this time, the second motor 37 is turned off, and the threaded sleeve is threadedly connected on the screw 31. The lateral movement of the rotating part 321 can be achieved by rotating the screw 31. When it is necessary to move up and down, it is only necessary to control the extension and retraction of the telescopic rod 42 to control the up and down movement.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
