Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a material compaction device for a loader. Background Technology

[0002] The material compaction device of a loader is an auxiliary device installed on the working device of the loader to squeeze and compact loose materials to increase the bulk density of the materials or reduce the spillage during transportation. Its core function is to enhance the compactness of the materials through mechanical force. It is suitable for scenarios such as warehousing, transportation, and site leveling. However, in the existing technology, some compaction devices have a small single-operation coverage area and need to perform impact operations point by point. In large-area operations with high fills, the operating efficiency is lower than that of traditional vibratory rollers or large impact rollers, which may lead to slower construction progress. Furthermore, the time spent replacing the compaction plates is relatively long, which will increase the time cost to a certain extent.

[0003] A material compaction device for a loader is proposed to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a material compaction device for a loader, in order to solve the problems mentioned in the background art. In the current technology, some compaction devices have a small single-operation coverage area and need to perform impact operations point by point. In large-area operations in high fills, the operating efficiency is lower than that of traditional vibratory rollers or large impact rollers, which may lead to slower construction progress. Furthermore, the time spent replacing the compaction plates is relatively long, which will increase the time cost to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material compaction device for a loader, comprising a compaction device, wherein a connecting disc is fixedly connected to the bottom surface of the compaction device;

[0006] An installation plate is fixedly installed on the bottom surface of the connecting plate, and a threaded sleeve is fixedly connected to the middle of the bottom surface of the installation plate. A compaction plate is threadedly connected to the inside of the connecting sleeve.

[0007] Also includes:

[0008] The threaded sleeve has through-fixing components symmetrically arranged on both sides of its surface;

[0009] The through-fixing component includes a connecting sleeve that is fixedly connected to the threaded sleeve;

[0010] The connecting sleeve has a threaded through rod inside.

[0011] Preferably, rubber washers are fitted on both sides of the threaded through rod, one side of the rubber washer is fixedly connected to the connecting sleeve, and nuts are threaded onto both sides of the threaded through rod.

[0012] Preferably, the connecting sleeve has symmetrically installed arc-shaped buffer pads inside, and the bottom surface of the arc-shaped buffer pads is in contact with the threaded through rod.

[0013] Preferably, the threaded through rod is made of a high-strength alloy material.

[0014] Preferably, a mounting block is fixedly connected to the back of the compaction device, and a loader connecting shaft is provided on the side surface of the mounting block away from the compaction device.

[0015] Preferably, the compaction plate has a through hole on one side surface near the top, and the through hole is connected to a threaded through rod.

[0016] Preferably, the threaded sleeve has symmetrical holes on both sides, and a polyurethane bushing is fixedly installed inside the holes. The holes are connected to the threaded through rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the material compaction device for a loader, by setting a through-fixing component, makes it easier to replace the compaction plate, thereby increasing the replacement speed of the compaction plate to a certain extent, thus reducing downtime and time costs. The specific details are as follows:

[0018] 1. By setting up a through-fixing assembly, when the compaction plate needs to be replaced according to the actual site conditions, the nut and rubber washer are removed from the threaded rod using tools. The threaded rod is then pulled to completely separate it from the threaded sleeve and the compaction plate. The compaction plate is then rotated to separate it from the threaded sleeve, allowing for replacement. When installing the compaction plate, it is connected threadedly to the threaded sleeve, aligning the through hole on the compaction plate with the hole on the threaded sleeve. The threaded rod is then passed through the compaction plate and the threaded sleeve, and finally installed on the threaded rod using a rubber washer and nut. The rubber washer also helps to buffer the vibration generated during operation. Meanwhile, the connecting sleeve is made of rubber, and the inside of the connecting sleeve is symmetrically equipped with arc-shaped buffer pads. The arc-shaped buffer pads are closely connected to the threaded through rod. This allows the local pressure of the threaded through rod to be dispersed to a larger area through the cooperation between the connecting sleeve and the arc-shaped buffer pads, reducing the stress peak by 40% to 60% and reducing the risk of fatigue cracks caused by stress concentration on the surface of the threaded through rod. At the same time, the threaded through rod is made of high-strength alloy material, which makes the threaded through rod strong, thus reducing the risk of breakage. In addition, an anti-loosening hydraulic nut is added on the basis of the threaded connection. By injecting high-pressure oil, the nut and the bolt are made to have an interference fit, which not only ensures the stability of the preload, but also reduces the impact of vibration on the threaded through rod through the buffering effect of the hydraulic oil.

[0019] 2. By setting up an installation block and a loader connecting shaft, the compaction device is connected to the loader connecting shaft through the installation block and the bucket pin. At the same time, a buffer ring is set between the installation block and the loader connecting shaft. The buffer ring absorbs part of the vibration energy through its own elastic deformation, avoiding rigid impact between the pin and the connecting ear plate, reducing the vibration and noise of the whole machine, and reducing fatigue damage to the loader structure. At the same time, the buffer ring can isolate the direct metal contact between the pin and the ear plate, reducing the intrusion of dust and mud in the working environment and reducing the risk of pin corrosion; it also prevents the pin from being scratched by the edge of the ear plate when shaking, maintaining the strength of the pin.

[0020] 3. By setting holes and polyurethane bushings, the polyurethane bushings are installed inside the holes, so that the inner hole and the threaded through rod are interference fit, while the outer circle and the hole are clearance fit. The damping characteristics of polyurethane are used to consume vibration energy and reduce the vibration intensity transmitted to the compaction device. Attached Figure Description

Figure 1-6 As shown, by setting the through-fixing component 8, it is easier to replace the compaction plate 7, thereby increasing the replacement speed of the compaction plate 7 to a certain extent, thus reducing downtime and time costs. Meanwhile, the compaction device 1 is the same as the prior art in terms of working principle and power connection.

[0030] Rubber washers 803 are fitted on both sides of the threaded through rod 802. One side of the rubber washer 803 is fixedly connected to the connecting sleeve 801. Nuts 804 are threadedly connected to both sides of the threaded through rod 802. Arc-shaped buffer pads 805 are symmetrically installed inside the connecting sleeve 801. The bottom surface of the arc-shaped buffer pads 805 is in close contact with the threaded through rod 802. The threaded through rod 802 is made of high-strength alloy material. Figure 3 , 4 As shown, when installing the compaction plate 7, after threading the compaction plate 7 into the threaded sleeve 6, aligning the through hole 9 on the compaction plate 7 with the hole 10 on the threaded sleeve 6, the threaded through rod 802 is passed through the compaction plate 7 and the threaded sleeve 6, and then installed on the threaded through rod 802 using rubber washer 803 and nut 804, thus completing the installation of the compaction plate 7. Simultaneously, the rubber washer 803 serves to buffer the vibration force generated when the compaction plate 7 is in operation. The connecting sleeve 801 is made of rubber, and symmetrically installed arc-shaped buffer pads 805 are installed inside the connecting sleeve 801. The arc-shaped buffer pads 805 are fitted and connected to the threaded through rod 802, which makes... The cooperation between the connecting sleeve 801 and the arc-shaped buffer pad 805 can disperse the local pressure of the threaded through rod 802 to a larger area, reducing the stress peak by 40% to 60% and reducing the risk of fatigue cracks caused by stress concentration on the surface of the threaded through rod 802. At the same time, the threaded through rod 802 is made of high-strength alloy material, which makes the threaded through rod 802 strong, thus reducing the risk of breakage. In addition, based on the threaded connection, an anti-loosening hydraulic nut 804 is added. By injecting high-pressure oil, the nut 804 and the bolt are made to have an interference fit, which not only ensures the stability of the preload, but also reduces the impact of vibration on the threaded through rod 802 through the buffering effect of the hydraulic oil.

[0031] A mounting block 4 is fixedly connected to the back of the compaction device 1. A loader connecting shaft 5 is provided on the side of the mounting block 4 away from the compaction device 1. Figure 2 As shown, by setting the mounting block 4 and the loader connecting shaft 5, the compaction device 1 is connected to the loader connecting shaft 5 through the mounting block 4 and the bucket pin. At the same time, a buffer ring is set between the mounting block 4 and the loader connecting shaft 5. The buffer ring absorbs part of the vibration energy through its own elastic deformation, avoiding rigid impact between the pin and the connecting ear plate, reducing the vibration noise of the whole machine, and reducing fatigue damage to the loader structure. At the same time, the buffer ring can isolate the direct metal contact between the pin and the ear plate, reducing the intrusion of dust and mud in the working environment and reducing the risk of pin corrosion; it also prevents the pin from being scratched by the edge of the ear plate when shaking, maintaining the strength of the pin.

[0032] A through hole 9 is provided on one side surface of the compaction plate 7 near the top, and the through hole 9 is connected to the threaded through rod 802. Figure 5 As shown, the through hole 9 and the threaded through rod 802 are connected to each other, so that the compaction plate 7 can play an auxiliary stabilizing role.

[0033] The threaded sleeve 6 has symmetrical holes 10 on both sides. A polyurethane bushing 11 is fixedly installed inside the hole 10. The hole 10 is connected to the threaded through rod 802. Figure 5 , 6 As shown, by setting the hole 10 and the polyurethane bushing 11, the polyurethane bushing 11 is installed inside the hole 10, so that the inner hole is interference-fitted with the threaded through rod 802, while the outer circle is clearance-fitted with the hole 10. The damping characteristics of polyurethane are used to consume vibration energy and reduce the vibration intensity transmitted to the compaction device 1.

[0034] Working principle: Before using the material compaction device of this type of loader, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6As shown, firstly, by setting the through-fixing component 8, and then, depending on the actual site conditions, when it is necessary to replace the compaction plate 7, the nut 804 and rubber washer 803 are removed from the threaded rod using a tool. Then, by pulling the threaded through rod 802, the threaded through rod 802 is completely separated from the threaded sleeve 6 and the compaction plate 7. Then, by rotating the compaction plate 7, it is separated from the threaded sleeve 6, allowing the compaction plate 7 to be replaced. When installing the compaction plate 7, after threading the compaction plate 7 into the threaded sleeve 6, aligning the through hole 9 on the compaction plate 7 with the hole 10 on the threaded sleeve 6, the threaded through rod 802 is passed through the compaction plate 7 and the threaded sleeve 6. Then, the rubber washer 803 and nut 804 are installed on the threaded through rod 802, thus completing the installation of the compaction plate 7. Simultaneously, the rubber washer 803 helps to dampen the vibration generated when the compaction plate 7 is in operation. The connecting sleeve 801 is made of rubber, and an arc-shaped buffer pad 805 is symmetrically installed inside the connecting sleeve 801. The arc-shaped buffer pad 805 is in close contact with the threaded through rod 802. This allows the local pressure of the threaded through rod 802 to be dispersed to a larger area through the cooperation between the connecting sleeve 801 and the arc-shaped buffer pad 805, reducing the stress peak by 40% to 60% and reducing the risk of fatigue cracks caused by stress concentration on the surface of the threaded through rod 802. At the same time, the threaded through rod 802 is made of high-strength alloy material, which makes the threaded through rod 802 strong, thus reducing the risk of breakage of the threaded through rod 802. In addition, an anti-loosening hydraulic nut 804 is added on the basis of the threaded connection. By injecting high-pressure oil, the nut 804 and the bolt are interference-fitted, which not only ensures the stability of the preload, but also reduces the impact of vibration on the threaded through rod 802 through the buffering effect of the hydraulic oil.

[0035] Secondly, by setting the mounting block 4 and the loader connecting shaft 5, the compaction device 1 is connected to the loader connecting shaft 5 through the mounting block 4 and the bucket pin. At the same time, a buffer ring is set between the mounting block 4 and the loader connecting shaft 5. The buffer ring absorbs part of the vibration energy through its own elastic deformation, avoiding rigid impact between the pin and the connecting ear plate, reducing the vibration noise of the whole machine, and reducing fatigue damage to the loader structure. At the same time, the buffer ring can isolate the direct metal contact between the pin and the ear plate, reducing the intrusion of dust and mud in the working environment and reducing the risk of pin corrosion; it also prevents the pin from being scratched by the edge of the ear plate when shaking, maintaining the strength of the pin.

[0036] Finally, by setting the hole 10 and the polyurethane bushing 11, the polyurethane bushing 11 is installed inside the hole 10, so that the inner hole is interference-fitted with the threaded through rod 802, while the outer circle is clearance-fitted with the hole 10. The damping characteristics of polyurethane are used to consume vibration energy and reduce the vibration intensity transmitted to the compaction device 1.

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.
