An extension block is provided on one side of the installation block. A fixing plate is provided on the bottom of the installation block. An installation table is provided on one side of the connecting block. A motor is provided inside the installation table. For this excavator guide wheel, by setting a scraper, larger soil can be separated, reducing the amount of it entering the connection of the guide wheel. When the motor starts, the crushing knife can rotate, and the crushing knife can further finely crush the soil entering the connection of the guide wheel, thereby reducing the impact of the soil on the connection of the guide wheel.

[0004] However, the inventor found that this device has the following problems: When the scraper separates the soil, it only blocks the soil and cannot push aside the blocked soil. The soil will accumulate on the surface of the scraper. After accumulating to a certain amount, the soil will still enter the connection of the guide wheel from around the scraper, affecting the subsequent use of the guide wheel.

[0030] Embodiment 1:

[0031] As Figures 1 to 6As shown in the figure, a guide wheel for an excavator guiding device includes a guide wheel 1, a mounting frame 2, a cleaning component 3 and a driving component 4; a guide groove 11 is provided on the guide wheel 1; the mounting frame 2 is installed outside the guide wheel 1, and the mounting frame 2 includes a cross bar 21, and mounting plates 211 are symmetrically arranged on the side wall of the cross bar 21 close to the guide groove 11; the cleaning component 3 is located on the rotation path of the guide groove 11, and the cleaning component 3 includes a dust-raising shaft 31, a scraping plate 32 and a cleaning shaft 33. The dust-raising shaft 31 and the cleaning shaft 33 are rotatably arranged on the mounting plate 211, and the scraping plate 32 is arranged between the dust-raising shaft 31 and the cleaning shaft 33; the driving component 4 is arranged on the mounting frame 2, and the driving component 4 drives the dust-raising shaft 31 and the cleaning shaft 33 to rotate.

[0032] As Figure 1 , 2 shown in the figure, the mounting frame 2 further includes mounting arms 22 and connecting arms 23; the mounting arms 22 are symmetrically arranged on both sides of the guide wheel 1; the connecting arms 23 connect the cross bar 21 and the mounting arms 22.

[0033] It should be noted here that mounting holes are provided on the mounting arms 22, bearings are arranged in the mounting holes, the guide wheel 1 is sleeved in the bearings, and the mounting arms 22 are in a vertically upward state when installed in the excavator.

[0034] As Figure 1 , 2 , as shown in Figure 4, mounting holes 321 are provided on the scraping plate 32, mounting grooves 212 are provided on the cross bar 21, and the scraping plate 32 is installed in the mounting grooves 212 through bolts 322.

[0035] It is worth mentioning here that by providing the mounting grooves 212 on the cross bar 21, it is convenient to install and position the scraping plate 32 in the mounting grooves 212, and the scraping plate 32 is fixed in the mounting grooves 212 through bolts 322.

[0036] As Figure 1 , 2 shown in the figure, a dust-raising groove 213 is provided on the cross bar 21 above the dust-raising shaft 31.

[0037] It is worth mentioning here that by providing the dust-raising groove 213 at the cross bar 21 above the dust-raising shaft 31, it is convenient for the dust-raising shaft 31 to raise and throw the dust in the guide groove 11 and on the surface of the scraping plate 32, reducing the amount of dust.

[0038] As Figure 3 , 4 shown in the figure, a number of spirally wound spiral blades 311 are provided on the dust-raising shaft 31, a blade 323 is provided at the bottom of the scraping plate 32, and a number of straight plate blades 331 are provided on the cleaning shaft 33.

[0039] It is worth mentioning here that a spiral blade 311 is provided on the dust-raising shaft 31. When the dust-raising shaft 31 stirs the dust, some of the dust will be propelled by the spiral blade 311 and fly towards the side of the guide wheel 1, preventing the flying soil from returning to the rotation path of the guide wheel again. The blade 323 helps to cut and separate the dust particles, and the straight plate blade 331 is conducive to scraping off the residual dust on the guide groove 11 without contacting the guide groove 11.

[0040] Such as Figure 2 、 3 As shown, the drive assembly 4 includes a drive member 41, a transmission shaft 42, and a gear set 43; the drive member 41 is fixedly installed on the connecting arm 23 on one side; one end of the transmission shaft 42 is connected to the output end of the drive member 41, and the transmission shaft 42 is rotatably arranged on the cross bar 21; the gear set 43 is arranged on one side of the mounting plate 211, and the gear set 43 includes a driving gear 431 and a pair of driven gears 432. The driving gear 431 is sleeved on the other end of the transmission shaft 42, and the driven gears 432 are respectively sleeved on the dust-raising shaft 31 and the cleaning shaft 33.

[0041] It should be noted here that the driving gear 431 in the gear set 43 is driven by the driving member 41 and rotates in the opposite direction to the guide wheel 1, and the pair of driven gears 432 driven by the driving gear 431 rotate in the same direction as the guide wheel 1.

[0042] Such as Figure 1 、 6 As shown, a protective cover 214 is further installed on the mounting plate 211, and the protective cover 214 wraps around the gear set 43.

[0043] It is worth mentioning here that setting the protective cover 214 outside the gear set 43 can better protect the gear set 43, prevent dust from entering the gear set 43 and affecting the meshing transmission between gears. At the same time, it can also reduce the noise generated by the meshing transmission of gears, improve the service life of the gear set 43, and reduce the failure rate.

[0044] Such as Figure 2 、 5 As shown, the guide wheel 1 rotates in the same direction as the dust-raising shaft 31 and the cleaning shaft 33. When the guide wheel 1 rotates, it sequentially passes through the dust-raising shaft 31, the scraper 32, and the cleaning shaft 33 in sequence.

[0045] It is worth mentioning here that, driven by a pair of driven gears 432, the dust collecting shaft 31 and the cleaning shaft 33 rotate in the same direction as the guide wheel 1, so that the dust collecting shaft 31 and the cleaning shaft 33 move in opposite directions when they come into contact with the dust in the guide wheel 1, which is more conducive to the dust collecting shaft 31 to push away the dust, and also conducive to the cleaning shaft 33 to scrape off the dust remaining in the guide groove 11, thereby improving the cleaning effect.

[0046] The working process is as follows:

[0047] The guide wheel 1 is installed in the excavator through the mounting arm 22. When the excavator is moving, dust falls into the guide groove 11 of the guide wheel 1. The dust rotates under the drive of the guide wheel 1 and first contacts the dust raising shaft 31. Driven by the drive assembly 4, the dust raising shaft 31 lifts up part of the dust and throws it away from the guide wheel 1. The remaining dust continues to rotate with the guide wheel and contacts the scraper 32. The scraper 32 blocks part of the dust again. When the dust particles pass through the blade 323 on the scraper 32, they are cut into smaller particles. At the same time, the dust raising shaft 31 takes away the dust accumulated on the scraper 32. The remaining dust in the guide groove 11 finally contacts the cleaning shaft 33 and is scraped off by the cleaning shaft 33 and leaves the guide groove 11.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
