Abstract
Description
Technical Field
[0001] This utility model relates to a wheel track, and more particularly to an excavator wheel track. Background Technology
[0002] Tracks are flexible chains driven by a drive sprocket, surrounding the drive sprocket, road rollers, idler sprocket, and track carrier sprocket. They play a vital role in both military and industrial applications; for example, large machinery such as excavators and tanks frequently use tracks as moving parts. Excavators, as construction machinery, have gradually replaced a significant amount of manual labor in excavating buildings, factories, canals, and digging earth, while also improving work efficiency. Therefore, excavators have become an indispensable tool in excavation work.
[0003] Currently, excavator tracks accumulate a large amount of mud during use. This mud gets embedded in the track gaps, increasing the excavator's weight, slowing down its movement during digging, reducing work efficiency, increasing fuel consumption during movement, and causing the mud to dry and harden over time, leading to deformation in the track gaps.
[0004] However, when mud gets stuck on the existing tracks, the mud can be cleaned by a movable brush plate. But for harder mud, the brush on the brush plate cannot remove it, making cleaning difficult, affecting the normal use of the tracks, making it inconvenient to move, and reducing the movement speed.
[0005] Therefore, it is necessary to develop a new type of excavator track to solve the above-mentioned technical problems. Utility Model Content
[0006] To address the shortcomings of the aforementioned technologies, this utility model provides an excavator wheel track.

[0016] This utility model proposes an excavator track system. By setting a translation mechanism on the load-bearing plate, the translation mechanism drives a cleaning mechanism to clean the tracks.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] Example 1
[0022] like Figure 1The excavator track shown includes a load-bearing plate 1, tracks 2 on both sides of the load-bearing plate 1, and a translation mechanism 3 on the load-bearing plate 1. Figure 2 As shown, the translation mechanism 3 includes a horizontally arranged positive and negative threaded rod 31, a gear 32 is sleeved in the middle of the positive and negative threaded rod 31, and sliders 33 are respectively arranged on both sides of the gear 32. The other end of the sliders 33 is respectively connected to a sliding cylinder 34. A guide seat 5 is arranged on the side of the bearing plate 1 near the track. The sliding cylinder 34 passes through the guide seat 5 and is connected to the cleaning mechanism 6. The cleaning mechanism 6 is provided with a mud scraper 61 that cooperates with the track 2.
[0023] By setting up a translation mechanism, when it is necessary to clean the mud on the tracks, the translation mechanism drives the cleaning mechanism to clean the tracks, which improves the convenience of use.
[0024] Specifically, the translation mechanism includes positive and negative threaded rods, with limit blocks at both ends of the positive and negative threaded rods. The positive and negative threaded rods are rotated by gears. During the rotation of the positive and negative threaded rods, the sliders on them move to the sides respectively. During the movement of the sliders, the sliding cylinders connected to them move. The sliding cylinders pass through the guide seats and drive the cleaning mechanism to move horizontally. During the movement of the cleaning mechanism, the mud scraper rotates to clean the mud on the track.
[0025] The lifting mechanism drives the cleaning mechanism to move up and down, so that the scraper wheel and the track gap are matched. The translation mechanism drives the cleaning mechanism to move horizontally, thereby cleaning the mud off the track gap. Compared with using a brush to clean the track, this design can clean harder mud and ensure the normal use of the track.
[0026] A lifting mechanism 4 is detachably installed on the bearing plate 1. The lifting mechanism 4 includes a vertically arranged guide column 41. A protective shell 43 is provided outside the guide column 41, and a lifting block 42 is sleeved on it. The bottom surface of the lifting block 42 is connected to a cylinder 45. The cylinder 45 drives the lifting block to move up and down along the guide column. A lifting cylinder 44 is provided at the other end of the lifting block 42. The lifting cylinder 44 is sleeved on the slider.
[0027] By setting up a lifting mechanism, the cleaning mechanism is moved downwards to the track gap. Specifically, the cylinder is activated, which moves the lifting block downwards along the guide column. This moves the lifting cylinder downwards along the guide column, causing the translation mechanism to move downwards during the downward movement of the lifting cylinder. This allows the scraper wheel to be placed on the track gap, facilitating subsequent cleaning.
[0028] In practical use, the lifting mechanism drives the lifting cylinder to descend, which in turn causes the sliding cylinder to descend under the guidance of the guide seat, causing the connecting frame to descend. Since the translation mechanism can drive the connecting frame to move, several mud scrapers are engaged with the track clearance. Activating the translation mechanism causes the sliding cylinder to move horizontally, which in turn causes the connecting frame to drive the mud scrapers to move horizontally, thereby cleaning the mud off the track. After this section of the track is cleaned, the lifting mechanism is activated to raise the sliding cylinder, which separates the mud scrapers from the track clearance, causing the track to rotate and align the uncleaned section with the mud scrapers. The above operation is repeated to clean the track.
[0029] The cleaning mechanism 6 includes a U-shaped connecting frame 62, within which a rotating shaft 63 is inserted. Several scraper wheels 61 are spaced apart on the rotating shaft 63. One end of the rotating shaft 63 is connected to the output of a motor. The motor drives the rotating shaft to rotate, thereby rotating the scraper wheels. The scraper blades on the scraper wheels remove the mud adhering to the tracks, improving the mud removal effect.
[0030] By setting up a cleaning mechanism, the mud on the track is cleaned under the drive of the translation mechanism. Specifically, the connecting frame is connected to the sliding cylinder, so that the sliding cylinder can drive the connecting frame to move up and down along the guide seat. At the same time, when the translation mechanism is started, the connecting frame can move horizontally under the drive of the sliding cylinder. During the movement of the connecting frame, because it is equipped with scraper wheels at intervals and the scraper wheels are in clearance fit with the track, the motor is started during the movement of the connecting frame. The motor drives the rotating shaft to rotate, the rotating shaft drives the scraper wheels to rotate, and the scraper blades on them rotate, thereby cleaning the mud on the track.
[0031] Preferably, there are three mud scrapers 61, and the spacing between any two mud scrapers 61 is the same as the spacing between the tracks.
[0032] By setting up three scraper wheels, the three gaps in the track can be cleaned at once, improving cleaning efficiency; by setting up the scraper wheels in conjunction with the track, the cleaning effect on harder mud is enhanced, ensuring the track's performance.
[0033] Specifically, the sliding cylinder 34 is fitted onto the outside of the positive and negative threaded rods. Since the sliding block is fitted onto the positive and negative threaded rods, the rotation of the positive and negative threaded rods can drive the two sliding blocks to move in opposite directions, thereby driving the sliding cylinder to move horizontally through the sliding blocks.
[0034] Specifically, a guide hole is provided on the guide seat 5 along the vertical direction, and the sliding cylinder 34 passes through the guide hole and moves up and down along it. By providing a guide hole on the guide seat, the sliding cylinder is restricted to moving only in the horizontal or vertical direction, ensuring stability during movement.
[0035] Specifically, a downward-opening groove is formed in the middle of the lifting cylinder 44, and the groove is fitted above the gear 32.
[0036] To enable the rotation of the positive and negative threaded rods, gears are fitted around them. The rotation of the gears drives the rotation of the positive and negative threaded rods connected to them, thereby enabling the translation mechanism to move horizontally.
[0037] Specifically, a drive wheel 8 is provided below the gear 32 and meshes with it. The drive wheel 8 is connected to the second motor 9 via a rotating shaft. The second motor 9 is located on the base.
[0038] By setting a drive wheel that meshes with a gear, the rotation of the drive wheel drives the gear to rotate. When the translation mechanism is working, the second motor is started, which drives the drive wheel to rotate. The rotation of the drive wheel drives the gear meshing with it to rotate, and the rotation of the gear drives the positive and negative threaded rods to rotate, thereby realizing the movement of the translation mechanism. During the movement of the translation mechanism, the cleaning mechanism is also moved to clean the mud on the tracks.
[0039] Specifically, the bottom surface of the protective shell 43 is provided with a base 7, and both ends of the base 7 are connected to the guide seat 5. The base serves a supporting function.
[0040] Example 2
[0041] An excavator track includes a load-bearing plate 1, tracks 2 on both sides of the load-bearing plate 1, and a translation mechanism 3 on the load-bearing plate 1. Figure 2 As shown, the translation mechanism 3 includes a horizontally arranged positive and negative threaded rod 31, a gear 32 is sleeved in the middle of the positive and negative threaded rod 31, and sliders 33 are respectively arranged on both sides of the gear 32. The other end of the sliders 33 is respectively connected to a sliding cylinder 34. A guide seat 5 is arranged on the side of the bearing plate 1 near the track. The sliding cylinder 34 passes through the guide seat 5 and is connected to the cleaning mechanism 6. The cleaning mechanism 6 is provided with a mud scraper 61 that cooperates with the track 2.
[0042] Side plates are installed on both sides of the load-bearing plate, and guide wheels are installed on both sides of the side plates. Tracks are provided on the outside of the guide wheels, and the two guide wheels are located at the two ends of the track inside. Several damping shock absorbers are installed at equal intervals on the top and bottom ends of the load-bearing plate, and a fixing frame is welded to the end of the damping shock absorber away from the load-bearing plate. Gears are connected inside the fixing frame through a rotating shaft, and the teeth of the gears are engaged in the guide grooves on the inner wall of the track.
[0043] The purpose of this utility model is to provide an excavator track system. By setting up a lifting mechanism, the cylinder is activated to drive the lifting block to move downward along the guide column. During the downward movement of the lifting cylinder, the translation mechanism moves downward, thereby placing the scraper wheel on the track clearance for easy subsequent cleaning. By setting up the translation mechanism, with the cooperation of the drive wheel and the gear, the gear drives the positive and negative threaded rod to rotate. The translation mechanism can drive the connecting frame to move, so that several scraper wheels are engaged with the track clearance. By setting up a cleaning mechanism, the motor drives the rotating shaft to rotate, which in turn drives the scraper wheel to rotate, thereby achieving the cleaning of mud from the track.
[0044] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
