Description

Technical Field

[0001] This utility model relates to the field of diesel loaders, specifically to a side-discharge diesel loader for coal mines. Background Technology

[0002] The side-dump diesel loader for coal mines is a type of engineering machinery used in underground coal mines, mainly for loading, transporting, and unloading materials such as coal. In existing technology, side-dump diesel loaders move via tracked drive. The lifting arm rotates around its hinge point with the front frame by extending and retracting the lifting cylinder, thereby raising or lowering the mounting frame and bucket to lift and lower materials. When it is necessary to dump materials to one side of the vehicle, the rotating shaft on one side is first pulled out, and then the side-dump cylinder is extended, causing the bucket to rotate around the rotating shaft on the other side, achieving side-dump discharge. However, the buckets of existing side-dump diesel loaders are U-shaped, and the side of the bucket furthest from the side-dump cylinder is open to the outside to facilitate dumping coal from the bucket. However, when the bucket is loaded with coal and needs to be moved to a designated location before dumping, there is no guard structure on one side of the bucket. Coal in the bucket may fall out during the loader's movement, increasing the subsequent collection and processing work for the fallen coal. Utility Model Content

[0003] To overcome the above-mentioned defects, the present invention provides a side-discharge diesel loader for coal mines, which solves the technical problem that in the prior art, the bucket does not have a guard structure on one side, and the coal in the bucket may fall out of the bucket during the movement of the loader, which increases the subsequent collection and processing work of the fallen coal.

[0004] According to one aspect, at least one embodiment of the present invention provides a side-discharge diesel loader for coal mines, including a loader body, the loader body including a bucket, the bucket being capable of tilting to the side, a discharge port being provided at one end of the bucket, and also including a baffle plate and a fixing mechanism. The baffle plate is rotatably disposed at the discharge port via a rotating mechanism, for discharging material by rotating the baffle plate after the bucket tilts to the side. The fixing mechanism is disposed on the bucket and the baffle plate, for fixing the bucket and the baffle plate, and for loading coal into the bucket.

[0005] Preferably, the rotating mechanism includes a rotating shaft, a mounting base, and a driving assembly. The rotating shaft is rotatably disposed at the discharge port, passes through the baffle plate, and is fixedly connected to the baffle plate. The mounting base is fixedly disposed on the bucket, one end of the rotating shaft is rotatably disposed within the mounting base, and the driving assembly is disposed on the mounting base for driving the rotating shaft to rotate the baffle plate.

[0006] Furthermore, the drive assembly includes a drive gear, a drive rack, and a hydraulic cylinder. The drive gear is rotatably disposed within the mounting base and is fitted onto one end of the rotating shaft and coaxially and fixedly connected to the rotating shaft. The drive rack is slidably disposed within the mounting base via a limiting component and meshes with the drive gear. The hydraulic cylinder is mounted on the mounting base, and the output end of the hydraulic cylinder is fixedly connected to one end of the drive rack.

[0007] Furthermore, the limiting component includes a limiting plate and a limiting groove. The limiting plate is fixedly connected to both ends of the driving rack. The mounting base has a limiting groove that cooperates with the limiting plate, and the inner wall of the limiting groove slides with the limiting plate.

[0008] As a further embodiment of this application, the fixing mechanism includes an arc-shaped protruding plate, an L-shaped connecting plate, and a locking bolt. The arc-shaped protruding plate is fixedly connected to the bucket, and the L-shaped connecting plate is fixedly connected to the baffle plate.

[0009] As a further aspect of this application, in order to enable the baffle plate to block the coal mine in conjunction with the bucket, the cross-section of the baffle plate and the discharge port are the same.

[0010] Based on the aforementioned solution, in order to provide the drive rack with a moving space, the mounting base is provided with a through groove that cooperates with the drive rack, and both limiting grooves are connected to the through groove.

[0011] Furthermore, in order to facilitate the disassembly of the locking bolt, the arc-shaped protruding plate is located at the bottom end of the bucket.

[0012] The beneficial effects of this utility model are as follows: In this invention, through the cooperation of the bucket, baffle plate, rotating mechanism, and fixing mechanism, the baffle plate is pre-sealed and fixed at the discharge port. The loader body is started to drive the bucket to collect the coal ore in the bucket and move it to the coal placement area. The locking bolts are removed, and the baffle plate is rotated 90 degrees by starting the hydraulic cylinder. At this time, the bucket is connected to the outside through the discharge port. During this process, the bucket can be tilted by the side discharge cylinder.

[0022] like Figures 1-4 As shown, it illustrates a side-discharge diesel loader for coal mines in one embodiment of the present invention, including a loader body 1, a loader body 1 including a bucket 2, the bucket 2 being capable of tilting to the side, a discharge port 3 being provided at one end of the bucket 2, and also including a baffle plate 4 and a fixing mechanism. It should be added that the bucket 2 is driven by the side discharge cylinder, which makes the bucket 2 rotate around the shaft on the other side to realize the side discharge of materials, and the side discharge cylinder is located on the side of the discharge port 3. like Figure 2 and Figure 3As shown, the baffle plate 4 is rotatably mounted at the discharge port 3 via a rotating mechanism. It is used to discharge material after the bucket 2 tilts to the side. To ensure the baffle plate 4 can effectively block coal from the discharge port 3, the cross-section of the baffle plate 4 and the discharge port 3 are identical. The rotating mechanism includes a rotating shaft 5, a mounting base 6, and a drive assembly. The rotating shaft 5 is rotatably mounted at the discharge port 3, passes through the baffle plate 4, and is fixedly connected to it. The mounting base 6 is fixedly mounted on the bucket 2 to form an mounting surface for easy installation of the hydraulic cylinder 9. One end of the rotating shaft 5 is rotatably mounted within the mounting base 6. The drive assembly is located within the mounting base 6. The mounting base 6 is used to drive the rotating shaft 5 to rotate the baffle plate 4. The driving assembly includes a driving gear 7, a driving rack 8, and a hydraulic cylinder 9. The driving gear 7 is rotatably mounted inside the mounting base 6 and is fitted onto one end of the rotating shaft 5 and fixedly connected to the rotating shaft 5 coaxially. The driving rack 8 is slidably mounted inside the mounting base 6 through a limiting assembly. The driving rack 8 meshes with the driving gear 7. The limiting assembly includes a limiting plate 10 and a limiting groove 11. Both ends of the driving rack 8 are fixedly connected to the limiting plate 10. The limiting plate 10 is located near the center of the driving rack 8. The mounting base 6 has a limiting groove that cooperates with the limiting plate 10. The length of the limiting groove 11 is less than the length of the mounting base 6, and the length of the limiting groove 11 is the movable distance of the drive rack 8, which can provide sufficient moving distance for the drive rack 8 to drive the drive gear 7 to rotate 90 degrees. The inner wall of the limiting groove 11 is in sliding fit with the limiting plate 10. The hydraulic cylinder 9 is mounted on the mounting base 6, and the output end of the hydraulic cylinder 9 is fixedly connected to one end of the drive rack 8. In order to provide moving space for the drive rack 8, the mounting base 6 is provided with a through groove 16 that mates with the drive rack 8. Both limiting grooves 11 are connected to the through groove 16. The baffle plate 4 is movable. In the case of “”, by activating the hydraulic cylinder 9, the output end of the hydraulic cylinder 9 pushes the drive rack 8 to move along the inner wall of the through groove 16. The drive rack 8 moves under the guidance of the limit plate 10 being engaged in the limit groove 11, and prevents the drive rack 8 from moving out of the mounting seat 6. The drive rack 8 drives the limit plate 10 to move along the inner wall of the limit groove 11, and drives the drive gear 7 to rotate. The drive gear 7 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the baffle plate 4 to rotate. At this time, the bucket 2 is connected to the outside through the discharge port 3. By tilting the bucket 2, the coal in the bucket 2 can be tilted and dumped to the designated position. like Figure 2 and Figure 4As shown, a fixing mechanism is installed on the bucket 2 and the baffle plate 4 to fix the bucket 2 and the baffle plate 4, and to cooperate with the bucket 2 in loading coal. The fixing mechanism includes an arc-shaped protruding plate 12, an L-shaped connecting plate 13, and a locking bolt 15. The arc-shaped protruding plate 12 is fixedly connected to the bucket 2, and the L-shaped connecting plate 13 is fixedly connected to the baffle plate 4. The L-shaped connecting plate 13 has an arc-shaped abutment surface 14 that cooperates with the arc-shaped protruding plate 12. The arc-shaped abutment surface 14 and the arc-shaped protruding plate 12 are in close contact and sliding cooperation. Both the arc-shaped protruding plate 12 and the L-shaped connecting plate 13 are threadedly engaged with the locking bolt 15. In order to facilitate the removal of the locking bolt 15, the arc-shaped protruding plate 12 is located at the bottom of the bucket 2. When it is necessary to transfer the coal, the hydraulic cylinder 9 is activated and the baffle plate 4 is driven to rotate, so that the baffle plate 4 opens the bucket 2. The material inlet 3 is blocked, and the baffle plate 4 drives the L-shaped connecting plate 13 to rotate and engage with the arc-shaped protruding plate 12. Then, the locking bolt 15 is used to thread-lock the L-shaped connecting plate 13 and the arc-shaped protruding plate 12, thus fixing them and fixing the baffle plate 4 and the bucket 2. After the bucket 2 collects the coal with the baffle plate 4, the loader body 1 drives the opening of the bucket 2 to face upwards, and then moves the loader body 1 to the coal placement position. At this time, the locking bolt 15 is at the bottom of the bucket 2, and relevant personnel can remove the locking bolt 15. The L-shaped connecting plate 13 and the arc-shaped protruding plate 12 are not fixedly connected. The baffle plate 4 can be rotated 90 degrees by starting the hydraulic cylinder 9. During this process, the bucket 2 can be tilted to the side by the side discharge cylinder, thus dumping the coal in the bucket 2 to the designated position.

[0023] Working principle: When the side-discharge diesel loader is operating in the coal mine, the loader body 1 is moved to the coal accumulation area. At this time, the baffle plate 4 blocks the discharge port 3, and the locking bolt 15 fixes the L-shaped connecting plate 13 and the arc-shaped protruding plate 12. By starting the loader body 1, the bucket 2 is driven to collect the coal in the bucket 2. The loader body 1 is then moved to the coal placement area. By removing the locking bolt 15, the L-shaped connecting plate 13 and the arc-shaped protruding plate 12 are no longer fixedly connected. The hydraulic cylinder 9 can be started. The output end of the hydraulic cylinder 9 pushes the drive rack 8 to move along the inner wall of the through groove 16. The drive rack 8 is at the limit plate 10. The bucket 2 moves under the guidance of the limit groove 11 and prevents the drive rack 8 from moving out of the mounting base 6. The drive rack 8 drives the limit plate 10 to move along the inner wall of the limit groove 11 and drives the drive gear 7 to rotate. The drive gear 7 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the baffle plate 4 to rotate. The baffle plate 4 rotates 90 degrees. At this time, the bucket 2 is connected to the outside through the discharge port 3. During this process, the bucket 2 can be tilted to the side by the side discharge cylinder. The tilting of the bucket 2 can tilt the coal in the bucket 2 to the designated position, avoiding the coal falling and being missed during the coal transfer process because one end of the bucket 2 is not equipped with a guard structure.
