Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of loading machine, specifically relates to a loading machine left and right side dumping bucket structure. BACKGROUND

[0002] The loading machine side dumping device is a working tool of the loading machine for operation in narrow spaces such as tunnels and mountainous roads. The loading machine side dumping device mainly comprises a side dumping bucket, a side dumping bracket, a side dumping oil cylinder, a side dumping limiting mechanism and the like. The side dumping bucket is connected with the side dumping bracket through a hinged pin shaft, is lifted through the side dumping oil cylinder, and performs a tilting action around the hinged pin shaft.

[0003] Moreover, the conventional design generally adopts a single-side tilting structure, i.e., can only complete the dumping action in a fixed direction (such as the left side or the right side). This structure exposes significant defects when dealing with complex operation scenarios: in narrow passages or irregular mine fields, if the material accumulation direction does not match the preset tilting direction of the bucket, the vehicle needs to be turned or adjusted twice to complete the unloading, resulting in an extended cycle time for a single operation. For example, when the bucket is full of ore and needs to be unloaded to the other side, the conventional structure needs to be repositioned through complex turning or reversing, directly reducing the equipment utilization rate; the single-side tilting structure causes the bucket, the vehicle frame and the hydraulic system to bear a long-term unidirectional load, causing problems such as metal fatigue and loose connections; to adapt to the multi-directional unloading requirement, the operator often adjusts the vehicle posture repeatedly to cooperate with the bucket action, significantly increasing fuel consumption.

[0004] A Chinese patent with the application number CN202221210100.3 relates to a loading machine side dumping device, which comprises a side dumping bucket and a side dumping bracket. The side dumping bucket is connected with the side dumping bracket through a hinged pin shaft. A limiting mechanism is arranged between the side dumping bucket and the side dumping bracket. A side dumping oil cylinder capable of tilting the side dumping bucket relative to the side dumping bracket is also arranged between the side dumping bucket and the side dumping bracket. The limiting mechanism comprises limiting plates I and II. The left and right sides of the bottom of the side dumping bucket are each provided with a limiting plate I. The left and right sides of the side dumping bracket are each provided with a limiting plate II. When the side dumping bucket is closed, the limiting plates I and II are in arc surface contact to limit the side dumping bucket. The limiting mechanism of the utility model adopts arc limiting plates to effectively increase the limiting contact area, more evenly distribute and transmit the working load, and thus improve the service life of the side dumping device.

[0005] Although the bucket can be left and right side dumped in the application, the oil cylinder is arranged in the middle, resulting in an excessively long force arm during side dumping, a large force on the oil cylinder, affecting the service life, and the oil cylinder in the middle easily causing incomplete side dumping of the material on the bottom surface of the bucket. In addition, although the limiting plates are arranged, they are damaged after long-term use, affecting the service life of the equipment and increasing the maintenance cost. UTILITY MODEL CONTENTS

[0030] like Figures 1-8 As shown: A bucket structure for left and right side unloading on a loader includes a bracket 1 and a bucket 3. The bracket 1 and the bucket 3 are rotatably connected by a bucket rotating part 2. A second hydraulic cylinder rotating part 7 is provided at the upper end of the bracket 1, and a first hydraulic cylinder rotating part 4 is provided near the lower end of the bucket 3. A hydraulic cylinder 6 is detachably and rotatably installed between the second hydraulic cylinder rotating part 7 and the adjacent first hydraulic cylinder rotating part 4.

[0031] The bucket rotating part 2 is equipped with a Hall sensor 5 for detecting the rotation angle of the bucket 3.

[0032] The bracket 1 includes a hydraulic cylinder rotating end 11 and a bucket rotating end 12, with the hydraulic cylinder rotating end 11 located at the upper end of the bucket rotating end 12.

[0033] A second rotating frame 111 is fixedly installed on the rotating end 11 of the hydraulic cylinder shown.

[0034] Two first rotating cylinders 120 are fixedly installed on both sides of the rotating end 12 of the bucket, and the two first rotating cylinders 120 are arranged symmetrically at intervals.

[0035] A pin cylinder 121 is vertically arranged on the outer surface of the first rotating cylinder 120 away from the bracket 1. The pin cylinder 121 penetrates the outer wall of the first rotating cylinder 120, and the through hole in the middle of the pin cylinder 121 communicates with the interior of the first rotating cylinder 120.

[0036] In this embodiment, the bucket 3 is a container for loading materials in the loader, and is configured in the shape of a bucket body. The bucket 3 is hinged with anti-overflow plates on both sides. When it is necessary to unload materials, the weight of the materials can push the anti-overflow plates open, making it convenient for the materials to fall. This function can be achieved simply by adding damping at the hinge between the anti-overflow plates and the bucket 3. The specific connection method is common knowledge and will not be described in detail here.

[0037] The bucket 3 is fixedly installed with a second rotating cylinder 31 on both sides near the lower end. The length of the second rotating cylinder 31 is adapted to the distance between two adjacent first rotating cylinders 120.

[0038] When the bucket 3 is not tilting, the second rotating cylinder 31 is coaxially arranged with the two corresponding first rotating cylinders 120.

[0039] The first rotating frame 110 is fixedly installed on both sides of the side of the bucket 3 near the rotating end 11 of the oil cylinder.

[0040] The two first rotating frames 110 are simultaneously located at the middle position in the height direction of the bucket 3.

[0041] like Figure 5 As shown, the bucket rotating part 2 includes a bucket rotating shaft 21 and a fixed pin 22.

[0042] The outer diameter of the bucket shaft 21 matches the middle hole of the first rotating cylinder 120 and the second rotating cylinder 31.

[0043] The bucket shaft 21 has two linearly arrayed pin holes 210, and the distance between the two pin holes 210 matches the distance between two adjacent pin cylinders 121.

[0044] The diameter of the pin hole 210 and the outer surface diameter of the fixed pin 22 are the same as the diameter of the through hole in the middle of the pin cylinder 121.

[0045] Each of the two first rotating cylinders 120 has an end cap 23 that is detachably installed on one end of each cylinder that is far apart from the other by bolts.

[0046] The Hall sensor 5 includes a sensor body 51 and a magnet 52. The sensor body 51 is fixedly installed on one end face of the two first rotating cylinders 120 that are close to each other, near the edge. The magnet 52 is fixedly installed on one end of the second rotating cylinder 31 that is close to the sensor body 51. In the initial state, that is, when the bucket 3 is not unloaded, the position of the magnet 52 corresponds to the position of the sensor body 51.

[0047] When in use, determine the tilt direction of the bucket 3, first insert the bucket shaft 21 into the two first rotating cylinders 120 and the second rotating cylinder 31 on one side of the tilt direction of the bucket 3, rotate the bucket shaft 21 to ensure that the two pin holes 210 are concentrically aligned with the two pin cylinders 121 respectively, then insert the two fixing pins 22 into the pin cylinders 121 and the pin holes 210 in sequence, and then install the end cap 23 on the two ends of the first rotating cylinders 120 that are far apart from each other. In this way, the bucket shaft 21 can be fixed on the bracket 1, and the bucket 3 can rotate around the bucket shaft 21.

[0048] When the bucket 3 rotates, the second rotating cylinder 31 drives the magnet 52 to rotate, so that the sensor body 51 senses the rotation angle of the magnet 52 and transmits a signal.

[0049] In this embodiment, the Hall sensor 5 measures angle by detecting changes in the magnetic field. When a magnet (such as a permanent magnet) rotates relative to the sensor, the intensity of the magnetic field detected by the sensor changes, thereby generating a corresponding electrical signal output, which is commercially available.

[0050] The hydraulic cylinder 6 adopts the double-ear connection method in the HSG series. The power output end of the hydraulic cylinder 6 is provided with a power end connecting ear plate 61, and the other end of the hydraulic cylinder 6 is provided with a mounting end connecting ear plate 62.

[0051] The second cylinder rotating part 7 includes a second rotating ear plate 71 fixedly installed on the second rotating frame 111. In this embodiment, the number of the second rotating ear plates 71 is set to four, of which two second rotating ear plates 71 form a group and are symmetrically arranged on both sides of the second rotating frame 111.

[0052] The first cylinder rotating part 4 includes two symmetrically spaced first rotating ear plates 41 fixedly installed on the first rotating frame 110.

[0053] In use, the power end connecting ear plate 61 is connected to the first rotating ear plate 41 by inserting into the first hydraulic cylinder shaft 42; the mounting end connecting ear plate 62 is connected to a set of two second rotating ear plates 71 by inserting into the second hydraulic cylinder shaft 72.

[0054] With this design, when the hydraulic cylinder 6 is started, the power output end of the hydraulic cylinder 6 extends, driving the bucket 3 to tilt to one side for unloading.

[0055] like Figures 3-4 As shown, when the bucket 3 needs to be tilted to the right, the second rotating cylinder 31 of the bucket 3 near the right side is connected to the bucket rotating end 12 near the right side on the bracket 1 through the bucket rotating part 2; then the power end connecting ear plate 61 of the hydraulic cylinder 6 is connected to the first hydraulic cylinder rotating part 4 near the right side of the bucket 3 through the first hydraulic cylinder rotating shaft 42, and the mounting end connecting ear plate 62 of the hydraulic cylinder 6 is connected to the second hydraulic cylinder rotating part 7 near the right side on the bracket 1 through the second hydraulic cylinder rotating shaft 72.

[0056] In this embodiment, the hydraulic control terminal of the cylinder 6 is connected to the hydraulic system of the loader, thereby realizing the control of the cylinder 6. The signal output terminal of the Hall sensor 5 is electrically connected to the control system of the loader through a wire.

[0057] The maximum rotation angle that ensures complete material unloading during bucket 3 is input into Hall sensor 5. When unloading material, hydraulic cylinder 6 is activated to drive bucket 3 to rotate and unload material. During this process, magnet 52 rotates simultaneously. When sensor body 51 detects that magnet 52 has rotated to a preset angle, it sends a signal back to the control system, which then stops hydraulic cylinder 6. This design avoids limit collisions during bucket 3 unloading and extends the service life of bucket 3.

[0058] like Figures 6-7 As shown, when the bucket 3 needs to be tilted to the left, the second rotating cylinder 31 of the bucket 3 near the left side is connected to the bucket rotating end 12 near the left side on the bracket 1 through the bucket rotating part 2; then the power end connecting ear plate 61 of the hydraulic cylinder 6 is connected to the first hydraulic cylinder rotating part 4 near the left side of the bucket 3 through the first hydraulic cylinder rotating shaft 42, and the mounting end connecting ear plate 62 of the hydraulic cylinder 6 is connected to the second hydraulic cylinder rotating part 7 near the left side on the bracket 1 through the second hydraulic cylinder rotating shaft 72, so that the left tilting can be achieved.

[0059] When switching between left and right, simply remove the end cover 23, pull out the fixing pin 22, and remove the bucket shaft 21. At the same time, remove the first cylinder shaft 42 and the second cylinder shaft 72 to replace the cylinder 6. The operation is convenient. By replacing the cylinder 6, the cylinder 6 is not installed in the middle position, which shortens the lever arm, reduces the force on the cylinder 6, extends its service life, and reduces production costs.

[0060] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
