[0023] The following is combined with Figure 1-3 The utility model is described in further detail.

[0024] The embodiment of the utility model discloses a clutch operating device for a snow sweeper.

[0025] Reference Figure 1-Figure 3A snowplow clutch operating device includes a first handrail frame 1 and a second handrail frame 2, a first clutch handle 3 is rotatably provided on the first handrail frame 1, a second clutch handle 4 is rotatably provided on the second handrail frame 2, a connecting piece 5 is provided on the second clutch handle 4, a limit block 6 is rotatably provided on the first handrail frame 1, a rotating block 7 is provided on the first clutch handle 3, the second clutch handle 4 is used to manipulate the limit block 6 to rotate through the connecting piece 5, the first clutch handle 3 is used to manipulate the rotating block 7 to rotate, pressing the first clutch handle 3 and the second clutch handle 4 to drive the rotating block 7 and the limit block 6 to rotate forward so that the rotating block 7 and the limit block 6 contact, and the limit block 6 restricts the rotating block 7 from reversing. When sweeping snow, press the first clutch handle 3 and the second clutch handle 4 at the same time to make the rotating block 7 and the limit block 6 rotate forward so that the rotating block 7 and the limit block 6 contact. Since the limit block 6 restricts the reverse rotation of the rotating block 7, the first clutch handle 3 can be released at this time, and only the second clutch handle 4 needs to be pressed. This effectively solves the problem that the staff needs to press the left clutch handle and the right clutch handle at the same time to complete the snow sweeping work, thereby improving work efficiency and safety.

[0026] In this embodiment, a first handle support base 8 is provided on the first handrail frame 1, and the first clutch handle 3 is rotatably provided on the first handle support base 8. A second handle support base 9 is provided on the second handrail frame 2. A first rotation axis 10 is provided on the first handle support base 8, and the second clutch handle 4 is rotatably provided on the second handle support base 9. The first clutch handle 3 and the rotating block 7 are rotatably provided on the first handle support base 8 via the first rotation axis 10. The first clutch handle 3 can be manipulated to drive the first rotation axis 10 to rotate and drive the rotating block 7 to rotate. The first handle support base 8 is fixed to the first handrail frame 1 by a fixing member. Similarly, the second handle support base 9 is fixed to the second handrail frame 2 by a fixing member. The fixing member can be a bolt, a latch, etc., and existing fixing parts are used.

[0027] The limit block 6, the rotating block 7 and the first clutch handle 3 are rotatably arranged on the first handle support seat 8, wherein the rotating block 7 and the first clutch handle 3 are rotatably arranged on the first handle support seat 8 through the first rotating shaft 10. The rotation of the first clutch handle 3 will drive the first rotating shaft 10

[0028] In this embodiment, the first clutch handle 3 is arranged on the left side of the snowplow, and the second clutch handle 4 is arranged on the right side of the snowplow. Specifically, the first clutch handle 3 is used to control the rotation of the stirring cage, and the second clutch handle 4 is used to control the movement of the entire machine. When the first clutch handle 3 and the second clutch handle 4 are pressed at the same time, the entire machine can both move forward and work.

[0029] In other embodiments, the positions and functions of the first clutch handle 3 and the second clutch handle 4 can be set according to actual conditions.

[0030] In this embodiment, the rotating block 7 is a cam sleeve, and the protruding end of the cam sleeve has a fitting surface 11, which is a plane. The limit block 6 has a fitting surface 2 12 that can fit with the fitting surface 11. After the fitting surface 11 and the fitting surface 2 12 fit together, the cam sleeve is restricted from reversing. When the second clutch handle 4 is released, the cable is connected.

[0031] In this embodiment, the limiting block 6 is provided with a through-hole, and the bonding surface 11 can be bonded to the bonding surface 11 through the through-hole.

[0032] A return spring 13 is provided on the limit block 6 , and the return spring 13 is used to apply a pre-tightening force to the limit block 6 to rotate upward, thereby realizing the return of the second clutch handle 4 and the first clutch handle 3 .

[0033] A second rotating shaft 14 is provided on the first handle support seat 8 , and the limiting block 6 and the return torsion spring are rotatably fitted on the first handle support seat 8 via the second rotating shaft 14 .

[0034] When the second clutch handle 4 is pressed, the end of the connecting cable located at the second clutch handle 4 moves upward, thereby causing the connecting cable located at one end of the limit block 6 to move downward, thereby driving the limit block 6 to rotate downward. When the first clutch handle 3 is pressed, the cam sleeve is driven to rotate through the first rotating shaft 10, and the cam sleeve rotates in the through hole. At this time, the first clutch handle 3 is released, the cam sleeve reverses and makes the contact surface 2 12 of the limit block 6 contact with the contact surface 1 11 of the cam sleeve, thereby limiting the cam sleeve from further reversal, completing the locking of the first clutch handle 3. When the work is completed, the second clutch handle 4 is released, the limit block 6 rotates upward, driving the cam sleeve to rotate forward first, and then when the cam sleeve is aligned with the through hole, the cam sleeve separates from the limit block 6, and the cam sleeve reverses, realizing the release between the first clutch handle 3 and the first handrail frame 1.

[0035] In other embodiments, in order to further improve the rotation return of the first clutch handle 3 , a torsion spring may be provided on the first clutch handle 3 .

[0036] A sleeve 15 is provided between the first handrail frame 1 and the second handrail frame 2. The connecting cable is connected to the second clutch handle 4 and the limit plate through the sleeve 15. The connecting cable completes the connection with the limit block 6 and the second clutch handle 4 through the sleeve 15, thereby protecting the connecting cable and effectively preventing the connecting cable from being directly exposed to the external environment, thereby reducing the risk of damage such as friction, pulling, and corrosion. This helps to extend the service life of the connecting cable and maintain its good operating performance.

[0037] An elastic member 16 is provided between the connecting cable and the second clutch handle 4. The elastic member 16 adopts a spring. The spring is used to apply an upward pre-tightening force to the second clutch handle 4 to loosen the second clutch handle 4 and the second handrail frame 2, thereby realizing automatic separation and convenient operation.

[0038] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the scope of protection of the present utility model.
