Description

Technical Field

[0001] This utility model relates to the field of scraper buckets, and in particular to an adjustable scraper bucket for a scraper bucket rock loading machine. Background Technology

[0002] A scraper bucket is a tool shaped like a rake, typically quite wide. It is mainly used in mining and water conservancy projects for clearing and loading materials. In mining, scraper bucket loaders are used in mining areas, employing a winch to pull the scraper bucket to scrape rocks and load them into mine cars. They are suitable for loading in coal mine horizontal shafts, inclined shafts, and inclined shafts in metal mines. When the scraper bucket is moving up or down slopes, the scraper angle needs to be changed and the scraper teeth replaced to ensure loading capacity and stability during operation.

[0003] The patent titled "An Adjustable Scraper Bucket for a Scraper Loader" (patent application number: 201220148874.8) discloses a scraper bucket that can adjust its working rear angle to suit different working environments. However, when adjusting the angle of this scraper bucket, it is fixed laterally by bolts and nuts. In order to ensure that the scraper bucket can stably scrape rocks, the bolts must be very tight to ensure that the side plates do not move. Therefore, adjusting the scraper bucket angle by loosening and tightening the bolts is quite laborious. Moreover, when scraping rocks, there will be a lot of dust. After long-term use, the bolts are prone to corrosion, causing bolt damage, which makes it impossible to fix the scraper bucket or to properly disassemble the bolts. Therefore, it is necessary to propose an adjustable scraper bucket for scraper loaders to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable scraper for a scraper loading machine to solve the problems of bolts being easily corroded and damaged, and the difficulty in adjusting the scraper angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable scraper bucket for a scraper bucket rock loading machine, comprising a fixed plate, two mounting inclined plates fixedly installed at one end of the fixed plate, a shaft fixedly installed at one end of the two mounting inclined plates, a scraper bucket claw rotatably installed on the shaft, two adjusting plates fixedly installed on the top of the scraper bucket claw, a sliding groove provided on the side of the two adjusting plates that are close to each other, and the sliding groove passing through the side of the two adjusting plates that are far from each other, a slider slidably installed on the inner wall of the sliding groove, a transverse groove provided on the fixed plate, a push-pull plate slidably installed in the transverse groove, two round shafts fixedly installed at the end of the push-pull plate near the adjusting plate, and the two round shafts are respectively located on both sides of the push-pull plate, the two round shafts are rotatably connected to the two sliders respectively, a sealing block fixedly installed at the end of the transverse groove away from the adjusting plate, a screw rotatably installed on the sealing block, and the screw is threadedly connected to the push-pull plate.

[0006] Preferably, a round handle is fixedly installed at the end of the screw away from the push-pull plate.

[0007] Preferably, the rake claw includes a supporting horizontal plate and rake teeth, and multiple rake teeth are provided. The top ends of the multiple rake teeth are fixedly installed on the lower surface of the supporting horizontal plate, and the supporting horizontal plate is provided with an elongated hole. The shaft passes through the interior of the elongated hole, and the two ends of the shaft are respectively fixedly installed on one end of two mounting inclined plates.

[0008] Preferably, each of the two sliders has a through hole on the side that is close to each other, and the through hole extends through the side that is far from each other. The two round shafts are respectively rotatably installed inside the two through holes.

[0009] Preferably, the upper surface of the fixing plate is provided with fixing holes, and the fixing holes penetrate the lower surface of the fixing plate, and the two fixing holes are symmetrically arranged about the central axis of the fixing plate.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. During operation, the scraper bucket is fixedly connected to the rock loading machine through the fixing plate, allowing for normal operation. Since the screw is located inside the fixing plate, external dust and moisture will not stick to the screw, causing corrosion and damage, resulting in a long service life.

[0012] 2. During operation, the angle of the rake claws can be easily adjusted by rotating the screw forward and backward. The adjustment is convenient, time-saving and labor-saving. When the rake claws are rakeing rocks, the pulling force of the rake claws acts on the screw thread. At this time, the screw is subjected to longitudinal shear force. The shear force mainly acts on the screw itself. As long as the screw has sufficient strength, the angle of the rake claws can be adjusted without using a large force, saving time and labor.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Generally, the rocks that the scraper buckets pick up are large and heavy. Scraper loaders with adjustable bucket angles require a large force on the scraper bucket. The friction between the two plates that are fixed together by bolts and nuts must be large enough to prevent the two plates from rotating relative to each other. When the scraper bucket is working, the lateral shear force between the two plates is large. The bolts and nuts must be tight enough to withstand the relative shear force. This requires a lot of force to tighten or loosen the bolts and nuts, requiring the use of tools and making the operation very laborious.

[0019] Therefore, this utility model provides such Figures 1-3 The adjustable scraper shown for the scraper loading machine includes a fixed plate 1. The upper surface of the fixed plate 1 is provided with a fixing hole 14, and the fixing hole 14 passes through the lower surface of the fixed plate 1. The two fixing holes 14 are symmetrically arranged about the central axis of the fixed plate 1. The fixed plate 1 can be fixed on the loading machine through the fixing hole 14 to facilitate the normal operation of the loading machine. This kind of setting is a conventional setting, so it will not be described in detail.

[0020] To address the issues of bolts being easily corroded and damaged, and the difficulty in adjusting the angle of the rake bucket, this invention features two mounting inclined plates 2 fixedly installed at one end of a fixed plate 1. A shaft 3 is fixedly installed at one end of each mounting inclined plate 2, and a rake bucket claw 4 is rotatably mounted on the shaft 3. Two adjusting plates 5 are fixedly installed on the top of the rake bucket claw 4. Each adjusting plate 5 has a sliding groove 6 on its adjacent side, extending through the opposing sides of the two adjusting plates 5. A slider 7 is slidably mounted on the inner wall of the sliding groove 6. A transverse groove 8 is provided on the fixed plate 1, and a push-pull plate 11 is slidably mounted within the transverse groove 8. Two round shafts 12 are fixedly installed at one end near the adjusting plate 5, and the two round shafts 12 are located on both sides of the push-pull plate 11. The two round shafts 12 are rotatably connected to two sliders 7 respectively. A sealing block 9 is fixedly installed at the end of the transverse groove 8 away from the adjusting plate 5. A screw 10 is rotatably installed on the sealing block 9. The screw 10 is threadedly connected to the push-pull plate 11. During operation, the rake bucket is fixedly connected to the rock loading machine through the fixing plate 1, and normal operation can be carried out. Since the screw 10 is located inside the fixing plate 1, external dust and moisture will not stick to the screw 10, causing corrosion and damage to the screw 10, and the service life is long.

[0021] When the angle of the rake claw 4 needs to be adjusted, the screw 10 is rotated. Since the push-pull plate 11 is installed inside the transverse groove 8 on the fixed plate 1, the push-pull plate 11 will not rotate. Under the reaction force, the push-pull plate 11 can be moved. The round shaft 12 on the push-pull plate 11 will drive the slider 7 to slide in the slide groove 6, which in turn can drive the adjusting plate 5 to swing. At this time, the adjusting plate 5 can drive the rake claw 4 to rotate. The angle of the rake claw 4 can be easily adjusted by rotating the screw 10 in both directions. The adjustment is convenient, time-saving and labor-saving. When the rake claw 4 rakes the rock, the pulling force of the rake claw 4 acts on the thread of the screw 10. At this time, the force on the screw 10 is a longitudinal shear force. The shear force mainly acts on the screw 10 itself. The screw 10 only needs to have sufficient strength. Therefore, the angle of the rake claw 4 can be adjusted without using a large force, which saves time and labor.

[0022] Furthermore, this utility model has a round handle 13 fixedly installed on the end of the screw 10 away from the push-pull plate 11. The round handle 13 makes it easier to rotate the screw 10 and saves effort.

[0023] It should be noted that when installing the scraper, space needs to be left between the fixed plate 1 and the rock loading machine to rotate the round handle 13, so as to facilitate the adjustment of the angle of the scraper claw 4. Alternatively, a motor can be used to replace the round handle 13 for adjustment, or the direction of force can be changed by bevel gears. The round handle 13 can be set on the upper surface of the fixed plate 1. This kind of setting is a conventional setting and can be selected according to the actual situation, so there is no restriction.

[0024] The rake claw 4 includes a support plate and rake teeth, and multiple rake teeth are provided. The tops of the multiple rake teeth are fixedly installed on the lower surface of the support plate. The support plate is provided with an elongated hole, and the shaft 3 passes through the inside of the elongated hole. The two ends of the shaft 3 are respectively fixedly installed on one end of two mounting inclined plates 2. The matching arrangement of the elongated hole and the shaft 3 facilitates the rotation of the rake claw 4 and the adjustment of the angle of the rake claw 4.

[0025] Two sliders 7 are provided with through holes on their sides that are close to each other, and the through holes extend through the sides of the two sliders 7 that are far apart from each other. Two round shafts 12 are respectively rotatably installed inside the two through holes. The through holes allow the round shafts 12 and the sliders 7 to rotate relative to each other, which can ensure the adjustment of the rake claws 4.
