Description

Technical Field

[0001] The utility model relates to the technical field of snow sweepers, in particular to a snow sweeper capable of switching between crawler travel and wheel travel. Background Art

[0002] Snowplows are an important gardening equipment for snow removal in winter. They mainly include control systems, snow collection devices, snow throwing devices, travel mechanisms, engines and other structures. They are mainly used for ice removal and snow removal on icy roads in winter. Therefore, if a snowplow adopts an ordinary wheel structure, there are certain limitations (such as slipping). The crawler travel mechanism has good obstacle crossing performance, so there are crawler snowplows on the market that travel by transmission crawlers. For example, the Chinese utility model patent with application number "202223083097.6" applied by the applicant in 2022 discloses a track mechanism of a self-propelled device, including a track and a triangular support frame and a track drive wheel placed in the track, and the track drive wheel is connected to the output shaft of the self-propelled device; the track drive wheel includes a wheel body, and the end faces of both sides of the wheel body are respectively provided with a circle of transmission flanges at equal intervals, and the transmission flanges extend along the axial direction of the wheel body; a plurality of pairs of transmission teeth are evenly spaced on the inner side wall of the track, and each pair of transmission teeth is formed with a guide groove corresponding to the wheel body, and a transmission tooth groove corresponding to the transmission flange is formed between two adjacent pairs of transmission teeth. In actual use, it is found that due to the small overall outer diameter of the track drive wheel, in order to maintain the moving speed, the output speed of the output shaft of the self-propelled device is relatively high. After the track mechanism is removed, it cannot be directly installed on the travel wheel for use, and the use function is subject to certain limitations. Utility Model Content

[0038] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0039] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0040] See also Figures 1 to 14 The utility model provides a snow sweeper which can switch between crawler travel and wheel travel, wherein Figure 1-Figure 13 In crawler travel mode, Fig.14 It is a wheeled travel mode.

[0041] The present embodiment provides a snowplow that can switch between tracked and wheeled travel, including a main body 1 on which an engine 2 and a control console 3 are mounted; power output shafts 4 are provided on both sides of the main body 1 for corresponding rotation output, and the power of the power output shaft 4 comes from the engine 2.

[0042] Furthermore, the snowplow has a track travel mode and a wheel travel mode; when in the track travel mode, the power output shaft 4 can be optionally installed with a track mechanism 5, and the track mechanism 5 includes a track drive wheel 501 and a drive track 502; when in the wheel travel mode, the power output shaft 4 can be optionally installed with a travel tire 6; the outer diameter size of the track drive wheel 501 is close to the outer diameter size of the travel tire 6 of the snowplow.

[0043] It should be emphasized that compared with the traditional crawler snowplow, the rotation speed of its power output shaft is very high. After the crawler structure is disassembled, it cannot be used with the travel tire, so the use function is limited to a certain extent. Therefore, in the embodiment of this specification, the size of the crawler drive wheel 501 is designed to be close to the size of the travel tire 6, and the entire crawler mechanism 5 is detachably mounted on the power output shaft 4. In addition, the outer diameter of the crawler drive wheel 501 is close to the outer diameter of the travel tire 6 of the snowplow. During the transportation and movement process (stop state), the crawler drive wheel 501 is larger in size and is also convenient for transportation.

[0044] In one example, if Figure 2 and Figure 3 As shown, after the track drive wheel 501 is inserted into the power output shaft 4, the positioning connection is achieved through the quick-release elastic baffle 9. The track mechanism 5 is symmetrically arranged on both sides of the body 1, and the two track mechanisms 5 are connected through the tensioning wheel shaft 510 and the connecting shaft 514.

[0045] In some embodiments, the track mechanism 5 further includes a support frame 503 for carrying the track drive wheel 501 , and a tensioning wheel 504 is mounted on the support frame 503 ; the lower edge of the outer circle of the track drive wheel 501 is flush with the lower edge of the outer circle of the tensioning wheel 504 .

[0046] It should be pointed out that the tensioning wheel 504 can not only tension the drive track 502, but also bear the load of the entire snowplow.

[0047] Among them, Figure 5 As shown, in this embodiment, the tensioning wheel 504 is close to the track driving wheel 501.

[0048] In some preferred embodiments, Figure 1-Figure 7 As shown, the power transmission of the crawler mechanism 5 is achieved through the following structure: Figure 6, transmission teeth 505 are evenly spaced in the transmission track 502, each pair of transmission teeth 505 is formed with a guide groove 506, and transmission tooth grooves 507 are formed between two adjacent pairs of transmission teeth 505; Figure 7 The wheel body 508 of the crawler drive wheel 501 is placed in the guide groove 506, and transmission protrusions 509 that mesh with the transmission tooth grooves 507 for transmission are distributed in annular and equidistant manner at both ends of the wheel body 508.

[0049] In some embodiments, Fig.12 and Fig.13 As shown, the tensioning wheel 504 is connected to the tensioning wheel shaft 510, and the support frame 503 is triangular; an adjustment seat 511 is installed on the support frame 503, and a hook bolt 512 and an adjustment nut 513 are installed on the adjustment seat 511, and the hook bolt 512 is hooked on the tensioning wheel shaft 510.

[0050] In some embodiments, the ratio of the outer diameters of the track drive wheel 501 and the traveling tire 6 is 0.9 to 1.1. Preferably, the outer diameters of the track drive wheel 501 and the traveling tire 6 are completely equal, that is, the ratio is 1:1.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, a manual adjustment mechanism 7 for adjusting the height position of the crawler mechanism 5 is installed on the control console 3 , so the operator can directly adjust the height position of the crawler mechanism 5 on one side of the control console 3 .

[0052] In some preferred embodiments, the manual adjustment mechanism 7 includes a control handle 701 disposed on the control console 3, a control box 702 mounted on the body 1, and a height adjustment rod 703 mounted on the crawler mechanism 5, see Figure 8 and Fig.11 , a control swing rod 704 is installed in the control box 702 for horizontal swinging, a lock 705 is arranged at one end of the control swing rod 704, and the other end of the control swing rod 704 relative to the lock 705 is connected to the control handle 701 through a pull rope 706; a plurality of lock holes 707 corresponding to the lock 705 are arranged on the height adjustment rod 703 in the vertical direction, and the lock 705 is engaged with the lock holes 707 at different height positions, and the height position of the crawler mechanism 5 relative to the body 1 is adjusted with the power output shaft 4 as the center of the circle. When adjusting, by pressing the control handle 701 on the control console 3, the control swing rod 704 is driven to swing horizontally through the pull rope 706, so that the lock 705 is separated from the current lock hole 707, and then the height adjustment rod 703 is adjusted upward or downward relative to the control box 702 as a whole; finally, the control handle 701 is released, so that the control swing rod 704 is reset and re-locked to the lock hole 707 at the current position, and the relative height position adjustment is completed.

[0053] In one example, if Fig.11 As shown, the locking member 705 is cylindrical.

[0054] In normal state, the lock 705 is placed in a lock hole 707 of the height adjustment rod 703, the control box 702 is fixed on the main body 1, the control rocker arm 704 is horizontally hinged and swingingly installed on the control box 702, and the height adjustment rod 703 is fixed on the track mechanism 5, one end of the track mechanism 5 is rotatably hinged and installed on the power output shaft 4, and the other end is movably connected to the control box 702 through the height adjustment rod 703. Therefore, by adjusting the relative position of the height adjustment rod 703 and the control rocker arm 704 in the control box 702, the relative height position of the entire track mechanism 5 relative to the main body 1 can be adjusted.

[0055] In some embodiments, see Figure 8 A return spring 711 is hooked between the end of the control rocker 704 away from the lock 705 and the control box 702 ; the return spring 711 always provides a thrust for the lock 705 to fall into the lock hole 707 .

[0056] In one example, if Figure 8 and Fig. 9 As shown, the height adjustment rod 703 is arranged at an end away from the power output shaft 4, and is specifically fixed on the tensioning wheel shaft 510 of the crawler mechanism 5.

[0057] In some embodiments, Figure 8 and Fig. 9 As shown, a sliding groove 708 is provided on the height adjustment rod 703, and a guide pin 709 that slides with the sliding groove 708 is correspondingly provided on the control box 702; a matching groove 710 corresponding to the locking element 705 is provided at one end of the control box 702 close to the locking element 705, and the locking element 705 is locked with the matching groove 710 and the corresponding locking hole 707, so that in the locked state, the height adjustment rod 703 and the control box 702 are locked and positioned firmly.

[0058] In some preferred embodiments, Figure 1-Figure 3 As shown, square columns 8 are arranged on both sides of the control console 3 , and the square columns 8 are inserted into the body 1 and fastened by bolts, so as to facilitate the rapid installation and disassembly of the control console 3 .

[0060] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
