[0046] like Figure 1-17 As shown, in one embodiment of the present invention, a snow outlet component steering assembly and a snowplow equipped with the snow outlet component steering assembly are provided. The snow outlet component steering assembly includes a frame 10, a handrail frame 20, a stirring cover 30, a snow outlet trough 40 and a first steering adjustment mechanism 50. The handrail frame 20 and the stirring cover 30 are both mounted on the frame 10.

[0047] The first steering adjustment mechanism 50 is used to adjust the orientation of the snow outlet 40. The first steering adjustment mechanism 50 includes a support base 51, a first gear 52, a second gear 53, a limiting component, and an operating lever 56. The support base 51 is mounted on the frame 10. Both the first gear 52 and the second gear 53 are rotatably mounted on the support base 51. The first gear 52 meshes with the second gear 53, and the second gear 53 is connected to the snow outlet 40. Both the first gear 52 and the second gear 53 are bevel gears, wherein the first gear 52 is a partially bevel gear. The limiting component restricts the rotation of the first gear 52. The operating lever 56 is movably fitted onto the support base 51. The operating lever 56 is used to drive the first gear 52 to rotate after the limiting component releases its restriction on the first gear 52.

[0048] This embodiment discloses a snow outlet assembly steering assembly and a snowplow. It uses a limiting component to restrict the rotation of the first gear 52. The user can release the limiting component's restriction on the first gear 52 using an operating lever 56, and also drive the first gear 52 to rotate. This causes the second gear 53, meshing with the first gear 52, to rotate the snow outlet chute 40, thereby adjusting the orientation of the snow outlet chute 40. After adjusting the orientation of the snow outlet chute 40, the limiting component can again restrict the position of the first gear 52, thus locking the position of the snow outlet chute 40 and fixing the snow discharge direction. This snow outlet assembly steering assembly facilitates user adjustment and position locking of the snow outlet chute 40, is easy to operate, and has a compact overall structure.

[0049] In one embodiment, the first gear 52 is provided with a connecting cylinder 521, which is rotatably mounted on the support base 51. The limiting assembly includes a limiting block 54 and a first elastic element 55. The limiting block 54 is movably sleeved outside the connecting cylinder 521 and is movably mounted on the support base 51. The moving direction of the limiting block 54 is parallel to the length direction of the operating rod 56. The limiting block 54 is provided with a first limiting protrusion 541. The first gear 52 is provided with a plurality of first limiting grooves 522 on the side facing the first limiting protrusion 541. The first limiting protrusion 541 can be engaged in any of the first limiting grooves 522. The operating rod 56 can rotate around the axis of the connecting cylinder 521 and move along the axis of the connecting cylinder 521. The operating rod 56 can pull the limiting block 54 to disengage the first limiting protrusion 541 from the first limiting groove 522. The first elastic element 55 is used to apply elastic force to the limiting block 54 to prevent the first limiting protrusion 541 from exiting the first limiting groove 522.

[0050] Specifically, the support base 51 is provided with a first bracket 511, the first bracket 511 is provided with an installation notch 512, the connecting cylinder 521 is rotatably mounted on the first bracket 511, and the limiting block 54 and the first elastic element 55 are both provided in the installation notch 512. The side wall of the connecting cylinder 521 has a first through hole 523 extending along the axial direction of the connecting cylinder 521. The operating rod 56 is movably inserted into the connecting cylinder 521, and the operating rod 56 is provided with a first pin 561, which can move within the first through hole 523. The first pin 561 is located between the limiting block 54 and the first gear 52, and the first elastic element 55 is located on the side of the limiting block 54 opposite to the first pin 561.

[0051] The first bracket 511 is provided with a second through hole 513 and a second limiting groove 514. The first limiting protrusion 541 passes through the second through hole 513 and engages with the first limiting groove 522. The second limiting groove 514 extends in a direction parallel to the length of the operating rod 56. The limiting block 54 is provided with a second limiting protrusion 542, which slides within the second limiting groove 514.

[0052] After the first limiting protrusion 541 passes through the second through hole 513, it will extend out of the first bracket 511. When the first limiting protrusion 541 is inserted into one of the first limiting grooves 522, the limiting block 54 will lock the first gear 52, thereby preventing the first gear 52 from rotating. At this time, the position of the snow outlet groove 40 will be locked.

[0053] When the user pulls the operating lever 56 backward, the first pin 561 on the operating lever 56 moves within the first through hole 523 and pushes against the limiting block 54, causing the limiting block 54 to move away from the first gear 52 on the first bracket 511. Since the second limiting protrusion 542 is confined within the second limiting groove 514, the limiting block 54 can only move in a direction parallel to the axial direction of the connecting cylinder 521 and will not rotate. Simultaneously, during this process, the limiting block 54 also compresses the first elastic element 55.

[0054] The first gear 52 will not move, and the first limiting protrusion 541 on the limiting block 54 will gradually disengage from the first limiting groove 522. The user then rotates the operating lever 56, causing the first pin 561 to simultaneously drive the connecting cylinder 521 and the first gear 52 to rotate. This, in turn, drives the first gear 52 to rotate, which in turn drives the second gear 53 and the snow outlet 40 to rotate, thus adjusting the orientation of the snow outlet 40. During the rotation of the operating lever 56, the limiting block 54 will not rotate because the second limiting protrusion 542 is restricted by the second limiting groove 514.

[0055] After adjusting the position of the snow outlet 40, the user pushes the operating lever 56 toward the first gear 52 to reset the operating lever 56. Under the elastic force of the first elastic element 55, the limiting block 54 will be quickly pushed to reset, so that the limiting block 54 abuts against the first pin 561 again. The first limiting protrusion 541 will also re-lock into the corresponding first limiting groove 522, thereby relocking the first gear 52.

[0056] In one embodiment, see Figure 11 and Figure 12 The snow discharge trough 40 is provided with a second bracket 41, which is connected to the second gear 53. The second gear 53 and the second bracket 41 do not rotate relative to each other. Therefore, when the first gear 52 drives the second gear 53 to rotate, it can drive the second bracket 41 and the snow discharge trough 40 to rotate.

[0057] Of course, in order to protect the first gear 52, the second gear 53, the limiting block 54, the first elastic element 55 and the first bracket 511, a protective cover 57 covering the above-mentioned components is provided on the support base 51.

[0058] In one embodiment, a snow cap 42 is rotatably mounted on the top of the snow outlet 40, and a second steering adjustment mechanism 60 is also included. The second steering adjustment mechanism 60 is used to adjust the orientation of the snow cap 42. The second steering adjustment mechanism 60 includes a gear shift bracket 61, a shift lever 62, a second elastic element 63, and a steering cable 64. The gear shift bracket 61 is mounted on the handrail frame 20 and has multiple gear shift notches. The shift lever 62 is movably mounted on the handrail frame 20 and can be engaged into any gear shift notch. The second elastic element 63 applies a spring force to the shift lever 62 to prevent it from disengaging from the gear shift notch. The steering cable 64 connects the shift lever 62 and the snow cap 42.

[0059] When it is necessary to adjust the orientation of the snow cap 42, the user rotates the shift lever 62 so that the shift lever 62 engages in the corresponding gear notch. During this process, the rotating shift lever 62 will also drive the snow cap 42 to rotate through the steering cable 64, thereby achieving the purpose of adjusting the orientation of the snow cap 42.

[0060] In one embodiment, to facilitate adjustment of the shift lever 62 and thus adjust the orientation of the snow cap 42, the shift bracket 61 is provided with clearance holes, which communicate with the shift notch. The shift lever 62 can move within the clearance holes, and the shift lever 62 is provided with a locking block 621 that engages with the shift notch.

[0061] In one embodiment, the handrail 20 is provided with a lug 21, and a second pin 22 is provided on the lug 21. The shift lever 62 is movably disposed on the second pin 22, and the second pin 22 is provided with a limiting head. A second elastic member 63 is disposed on the second pin 22, and the two ends of the second elastic member 63 abut against the shift lever 62 and the limiting head, respectively. In order to support the operating lever 56, a third bracket 23 is provided on the lug 21, and the operating lever 56 is movably disposed on the third bracket 23.

[0062] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
