Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings.

Referring to fig. 1 to 3, a cotton stalk puller, including main shaft 1, with 1 rotates the pressing assembly 2, steps on depression bar 3 and the centre gripping subassembly of connecting of main shaft, pressing assembly 2, stepping on depression bar 3 and centre gripping subassembly wind the circumference of main shaft 1 distributes, refers to the figure, and centre gripping subassembly, pressing assembly 2 and the actual mounted position and the installation angle of stepping on the pressing assembly need not to be injectd, only need to guarantee to realize that the hand can carry out the application of force to pressing assembly 2 application of force, centre gripping subassembly can grasp cotton stalk and the foot can carry out the application of force to stepping on depression bar 3.

The stepping rod 3 and the clamping assembly are fixedly connected with the main shaft 1; the main shaft 1 can rotate by applying force to the treading rod 3, so that the clamping assembly is driven to rotate, and the purpose of pulling the rod is achieved. The cotton stalk puller further comprises a connecting rod 8, one end of the connecting rod 8 is rotatably connected with the clamping assembly, the other end of the connecting rod 8 is rotatably connected with the pressing assembly 2, and the connecting rod 8 is used for clamping the cotton stalk through the pressing assembly. The clamping assembly 2 comprises a first clamping block 6, a second clamping block 7 and a clamping rod 4 fixedly connected with the main shaft 1, the first clamping block 6 is rotatably connected with a connecting rod 8 and is in sliding connection with the clamping rod 4, the second clamping block 7 is fixedly connected with the clamping rod 4, a jaw for clamping a cotton rod is formed between the first clamping block 1 and the second clamping block 7, the cotton rod is clamped in the jaw, the pressing assembly 2 is rotated by applying force to the pressing assembly 2, and the first clamping block 6 can move towards the second clamping block 7 under the action of the connecting rod 8, so that the purpose of fixing the cotton rod is achieved. And after the cotton stalk is fixed, the application of force to pressing the subassembly 2 just can control and drive the centre gripping subassembly through main shaft 1 along with rotating to reach the purpose of dead man, when the dead man, to stepping on the depression bar 3 application of force simultaneously, the intensity of labour that has significantly reduced.

Specifically, referring to fig. 4, the first clamping block 6 includes a clamping portion 61 and a limiting portion 62, and a sliding groove 63 engaged with the clamping rod 4 is formed between the clamping portion 61 and the limiting portion 62.
