[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0024] This utility model provides a convenient and flexible steering mechanism for a wood chipper through improvements. The technical solution of this utility model is as follows:
[0025] Example 1:
[0026] like Figure 1 As shown, a convenient and flexible turning mechanism for a wood chipper includes a hand handle 1, a fixed plate 2 and a fixed seat 3 are fixedly connected to the hand handle 1 respectively, the fixed plate 2 and the fixed seat 3 are both fixed to the hand handle 1 by welding, a turning cable 4 is provided on the fixed plate 2, and a limit pin 5 is provided on the hand handle 1. The length of the limit pin 5 is sufficient to block the turning handle 6 and not affect the position adjustment of the adjusting block 7, and also includes;
[0027] Steering handle 6 is rotatably connected to one side of fixed base 3. Steering handle 6 is connected to fixed base 3 through connecting shaft. Adjusting block 7 is slidably connected to steering handle 6. One side of adjusting block 7 is rotatably connected to one end of steering cable 4. One side of adjusting block 7 is provided with a protrusion to facilitate cable connection. Cable and adjusting block 7 are also connected through rotating shaft.
[0028] Adjusting component 8 is mounted on steering handle 6. Adjusting block 7 is connected to adjusting component 8. Adjusting component 8 can be used to adjust the cable travel and reduce cable idle travel.
[0029] The anti-accidental contact component 9 is mounted on the fixed base 3. Part of the anti-accidental contact component 9 is in contact with the steering handle 6. The anti-accidental contact component 9 is used to prevent the shredded branches from touching the steering handle 6 and causing the steering handle 6 to shift position when the shredder is working.
[0030] The specific steering process is as follows: After welding and fixing the hand handle 1 of this device to the frame of the shredder, the steering handle 6 is connected to the steering shaft (steering knuckle) of the front wheel of the shredder through a cable. When steering, the user pulls the steering handle 6, the cable is stressed, and the steering shaft (steering knuckle) of the front wheel is driven, which pushes the wheel bracket to deflect, causing the front wheel to deflect, thereby changing the direction of travel and completing the steering.
[0031] Example 2:
[0032] like Figure 2 As shown, in this embodiment, the adjusting component 8 includes a fixing frame 801 fixedly connected to one side of the steering handle 6. The fixing frame 801 is composed of two square plates distributed vertically along the steering handle 6. An adjusting screw 802 is rotatably connected to the inner wall of the fixing frame 801. The bottom end of the adjusting screw 802 is rotatably connected to the inner bottom wall of the fixing frame 801. A threaded hole adapted to the adjusting screw 802 is opened on the adjusting block 7. The adjusting screw 802 is screwed to the adjusting block 7. An adjusting knob 803 is rotatably connected to the upper surface of the fixing frame 801. The adjusting knob 803 is coaxially fixed with the adjusting screw 802.
[0033] Example 3:
[0034] like Figure 3 As shown, in this embodiment, the anti-accidental touch component 9 includes a fixing block 901 fixedly connected to one side of the fixing base 3. The fixing base 3 has a sliding groove, and a limiting block 902 is slidably connected to one side of the fixing base 3. One side of the limiting block 902 is inclined and fits against the steering handle 6.
[0035] In this embodiment, a limiting spring 903 is fixedly connected to one side of the limiting block 902, and the end of the limiting spring 903 away from the limiting block 902 is fixedly connected to one side of the fixing block 901. After the steering handle 6 is pushed manually, the limiting spring 903 will be compressed. After the steering is completed, the limiting spring 903 can return to its original position more quickly with the steering handle 6.
[0036] In this embodiment, a limiting hole is provided through the front side of the limiting block 902, through which the limiting block 902 and the fixing seat 3 pass together. A safety pin 10 is provided in the limiting hole, which can prevent the steering handle 6 from deviating due to the collision between the debris and the steering handle 6.
[0037] The specific working method is as follows: When using the convenient and flexible shredder steering mechanism, connect one end of the steering cable 4 to the steering shaft lug on the steering shaft. When steering, simply release the clutch brake and slowly turn the corresponding steering handle 6 until the steering is complete. Then slowly release the steering handle 6, which will automatically return to the position of the limit pin 5. During use, to prevent accidental activation, the user can use the safety pin 10 to fix the limit block 902 to the fixed seat 3, so that the limit block 902 abuts against the steering handle 6. When steering is needed, pull out the safety pin 10 to further ensure the safety of the operation. In addition, during use, the user can rotate the adjustment knob 803 to drive the adjustment screw 802 to adjust the travel of the cable, preventing excessive cable travel that would cause slow steering operation and ensuring that steering can be performed quickly.
[0038] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
