DETAILED DESCRIPTION

[0036] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] like Figure 1 As shown, a straw pulling device of the present invention comprises:

[0038] One rack;

[0039] A chassis 1, which is rotatably arranged on a frame;

[0040] A clamping mechanism, the clamping mechanism is installed in the chassis 1;

[0041] A driving mechanism is arranged on the chassis 1 and cooperates with the clamping mechanism in transmission.

[0042] like Figure 2 As shown, in a straw pulling device of the present invention, the clamping mechanism comprises:

[0043] A guide rod 13, the guide rod 13 is arranged in the chassis 1;

[0044] Two V-shaped pressing plates 6, both of which are provided with guide grooves, and both ends of the guide rod 13 extend into the guide grooves of the corresponding V-shaped pressing plates 6;

[0045] Two clamps 5 are respectively arranged at one end of a corresponding V-shaped pressing plate 6 .

[0046] like Figure 3 and Figure 4 As shown, in a straw pulling device of the present invention, the driving mechanism comprises:

[0047] a pedal 12, the pedal 12 is hinged on the upper side of the chassis 1;

[0048] Two push plates 15, the two push plates 15 are hinged to the lower side of the pedal 12 and are respectively arranged on the outer sides of the two V-shaped pressure plates 6;

[0049] An elastic sheet 16 , one end of which is connected to the lower side of the pedal 12 , and the other end of which abuts against the bottom of the case 1 .

[0050] When in use, a person steps on the pedal 12, and the pedal 12 moves downward, so that the two push plates 15 press the two V-shaped pressure plates 6 together to clamp the straw. Thereafter, the person continues to step on the pedal 12, and the chassis 1 will rotate in the frame to pull up the straw by the roots. During this process, the spring piece 16 is subjected to the pressure of the pedal 12 and undergoes elastic deformation. When the person stops stepping on the pedal 12, the pedal 12 will be reset under the elastic force of the spring piece 16, so that the next straw pulling can be carried out.

[0051] Obviously, compared with the prior art, the straw pulling device of the present invention has a light structure, is easy to operate, and has a low price and cost. It can completely remove the straw from the roots by pedaling, solving the problems of the existing straw removers that are difficult to pull up the straw by the roots and manual straw removal that is time-consuming and labor-intensive.

[0052] like Figure 3 As shown, in a straw pulling device of the present invention, a cover plate 7 is provided on the top of the chassis 1, and a slide groove for the elastic sheet 16 and the push plate 15 to slide is provided on the cover plate 7.

[0053] Such a design can ensure that the spring piece 16 and the push plate 15 move in the preset chute, so as to better complete the straw pulling work.

[0054] like Figure 5 As shown, in a straw pulling device of the present invention, a limiting block 17 is provided on the outer side of the V-shaped pressing plate 6 to prevent the V-shaped pressing plate 6 from directly contacting the inner side of the chassis 1 and causing damage.

[0055] like Figure 3 As shown, in a straw pulling device of the present invention, a base 14 is provided at the lower side of the pedal 12, and the upper ends of two push plates 15 are respectively connected to the base 14, so that disassembly and assembly are convenient.

[0056] like Figure 1 As shown, in a straw pulling device of the present invention, the pedal 12 is hinged to the cover plate 7 via a rotating shaft 8, and is convenient for assembly and disassembly.

[0057] like Figure 1As shown, in a straw pulling device of the present invention, the frame includes two vertically arranged support rods 9, a first cross bar 10 is provided between the upper ends of the two support rods 9, a second cross bar 2 is provided between the lower ends of the two support rods 10, and a chassis 1 is rotatably provided on the second cross bar 2; a torsion spring is provided between the second cross bar 2 and the bottom of the chassis 1.

[0058] The torsion spring is provided to ensure that when the pedal 12 is not stepped on, the chassis 1 can maintain a horizontal state on the second cross bar 2, thereby avoiding positional balance by adjusting the shape of the chassis 1.

[0059] like Figure 1 As shown, in a straw pulling device of the present invention, a third cross bar 4 is arranged at the lower end of the two second cross bars 2, the third cross bar 4 is located below the second cross bars 2, and a pair of supporting legs 3 are arranged on the lower side of the third cross bar 4, which can ensure that the straw pulling device of the present invention does not shake during use.
