Description

Technical Field

[0001] The utility model relates to the technical field of guide wheels, in particular to a guide wheel with a cleaning function. Background Art

[0002] As the name implies, the guide wheel is a wheel used for guidance. In the actual operation of the excavator, in order to facilitate walking, it is necessary to use the guide wheel for guidance, so that the crawler can be guided by limited limit to ensure the accuracy of walking;

[0003] In actual use, the existing guide wheels of excavators are often prone to a lot of impurities and dirt because the excavator works outdoors in a relatively harsh environment. As a result, the dirt and impurities adhere to the outer wall of the guide wheel for a long time, which can easily affect the guide wheel's effect on the track guidance. It does not have a cleaning function, and there are weeds wrapped around the rotating end shaft of the wheel body, which can easily aggravate the damage of the wheel body and affect its service life. Therefore, we propose a guide wheel with a cleaning function. Utility Model Content

[0004] The purpose of the utility model is to provide a guide wheel with a cleaning function, which solves the problems raised in the background technology.

[0006] By adopting the above technical solution, in actual use, the notch at the rear end of the scraper is used to fit the outer wall of the wheel body, so that the mud and impurities adhered to the outer wall of the wheel body can be scraped off, thereby avoiding long-term adhesion of mud and impurities on the surface of the wheel body to affect the guiding effect of the crawler. At the same time, when the scraper is worn out due to long-term use, rotating the adjusting bolt can drive the lifting block to descend, thereby causing the scraper to descend, so that the scraper and the wheel body have a high degree of fit, thereby ensuring the scraping effect.

[0007] As a preferred embodiment of the utility model, a limiting groove is provided on the inner wall of the support plate, an adaptive magnet slider is inserted into the inner cavity of the limiting groove, a spring is fixed on the top of the magnet slider, the outer end of the spring is fixedly connected to the top of the inner cavity of the limiting groove, a fixed block is fixedly connected to the outer wall of the magnet slider, a cutter is fixedly connected to the tail end of the fixed block, and an electromagnet is fixed on the lower side of the inner cavity of the limiting groove.

[0008] By adopting the above technical solution, in actual use, when weeds are entangled on the end shaft of the wheel body, the electromagnet is energized, so that suction force is generated on the magnet slider, thereby driving the fixed block to descend, and then the cutter is quickly lowered, so as to cut off the weeds wrapped around the end shaft of the wheel body, so that the weeds can be quickly removed and the long-term entanglement can be avoided to affect the wheel body.

[0009] As a preferred embodiment of the utility model, the distance between the cutter and the top of the wheel end shaft is the same as the distance between the bottom of the magnet slider and the top of the electromagnet.

[0010] By adopting the above technical solution, it is ensured that the cutter can cut the weeds after it descends, and the cutter and the end shaft of the wheel body are prevented from being damaged by impact.

[0011] As a preferred embodiment of the utility model, the position of the cutter and the vertical center plane of the wheel end axis are in the same plane.

[0012] By adopting the above technical solution, it can be ensured that the cutter can accurately cut the weeds after descending.

[0013] As a preferred implementation of the present invention, the four side walls of the lifting block are in contact with the four side walls of the inner cavity of the fixing box.

[0014] By adopting the above technical solution, the lifting stability of the lifting block can be ensured to avoid shaking.

[0015] As a preferred embodiment of the present invention, a mounting plate is fixedly connected to the top of the support plate, and mounting holes are provided on both sides of the top of the mounting plate.

[0016] By adopting the above technical solution, the arrangement of the mounting plate and the mounting holes makes it convenient to install and fix the entire device.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The guide wheel with a cleaning function of the technical solution of the present application is fitted on the outer wall of the wheel body by a scraper, so that the scraper can be used to scrape off impurities and soil on the surface of the wheel body during the rolling process of the wheel body, thereby avoiding the situation that long-term adhesion affects the guidance. At the same time, rotating the adjusting bolt can drive the lifting block to rise and fall, so that when the scraper is worn, the fit between the scraper and the wheel body can be adjusted in time, thereby ensuring the scraping effect;

[0019] By installing a cutter at the end shaft of the corresponding wheel body, the electromagnet can be energized regularly to generate suction to the magnet slider, so that the cutter can be driven to descend quickly to cut off the weeds wrapped around the outer wall of the end shaft of the wheel body, thereby achieving the effect of quickly cleaning the weeds, avoiding the situation where the wheel body is further damaged due to excessive entanglement of the weeds, and effectively extending the service life.

[0029] In actual use, the notch at the rear end of the scraper 31 is used to fit the outer wall of the wheel body 1, so that the mud and impurities adhering to the outer wall of the wheel body 1 can be scraped off, thereby preventing the mud and impurities from adhering to the surface of the wheel body 1 for a long time and affecting the guiding effect of the crawler. At the same time, when the scraper 31 is worn out after long-term use, the rotating adjustment bolt 33 can drive the lifting block 32 to descend, so that the scraper 31 is lowered, so that the scraper 31 and the wheel body 1 are closely attached to each other, thereby ensuring the scraping effect.

[0030] Furthermore, a mounting plate 21 is fixedly connected to the top of the support plate 2, and mounting holes 22 are provided on both sides of the top of the mounting plate 21. The arrangement of the mounting plate 21 and the mounting holes 22 facilitates the installation and fixation of the entire device.

[0031] Furthermore, the four side walls of the lifting block 32 are attached to the four side walls of the inner cavity of the fixing box 3, so as to ensure the lifting stability of the lifting block 32 and avoid shaking.

[0032] like Figure 1 and 3 As shown; a limited slot 23 is provided on the inner wall of the support plate 2, an adapted magnet slider 24 is inserted into the inner cavity of the limited slot 23, a spring 25 is fixed to the top of the magnet slider 24, the outer end of the spring 25 is fixedly connected to the top of the inner cavity of the limited slot 23, a fixed block 27 is fixedly connected to the outer wall of the magnet slider 24, a cutter 28 is fixedly connected to the tail end of the fixed block 27, and an electromagnet 26 is fixed to the lower side of the inner cavity of the limited slot 23;

[0033] In actual use, when weeds are wound around the end shaft of the wheel body 1, the electromagnet 26 is energized, so that suction force is generated on the magnet slider 24, so that the fixing block 27 is driven to descend, and then the cutter 28 is rapidly lowered, so that the weeds wound around the end shaft of the wheel body 1 are cut off, so that the weeds can be quickly removed, and the influence of long-term winding on the wheel body 1 can be avoided;

[0034] Furthermore, the distance between the cutter 28 and the top of the end shaft of the wheel body 1 is the same as the distance between the bottom of the magnet slider 24 and the top of the electromagnet 26, thereby ensuring that the cutter 28 can cut the weeds after it descends and avoiding the cutter 28 and the end shaft of the wheel body 1 from being damaged by impact;

[0035] Furthermore, the position of the cutter 28 and the vertical center plane of the end axis of the wheel body 1 are in the same plane, thereby ensuring that the cutter 28 can accurately cut the weeds after it is lowered.
