As shown in fig. 1 and 2, for better positioning, the first clamp 34 and the second clamp 35 are smoothly sleeved on the ventilation pipe a, the front end of the bottom plate is provided with a guide opening 25 for placing the ventilation pipe a, and the first clamp 34 and the second clamp 35 are arranged above the guide opening 25. Preferably, the guide opening 25 is splayed.
As shown in fig. 1 and 2, the method of use of the present invention:
placing the pipe pulling device on the grain surface; make its ventilation pipe a that inserts the establishment towards the grain face remove (for this tube drawing device of better controlling, can set up the camera on this tube drawing device's automobile body, acquire the image through the camera, dial the removal of tube drawing device reverse according to the image adjustment), finally make ventilation pipe a get into the guide port.
The bottom plate 2 is descended through the second cylinder 13, so that the bottom plate 2 is attached to the grain surface.
Then the piston rod of the first cylinder 44 is lowered, so that the first connecting rod 42 moves downwards, the first clamp 34 moves downwards, when the first clamp 34 moves downwards and is sleeved at the upper end of the ventilation pipe a, the ratchet wheels 321 rotate on the inner side wall of the sleeve from bottom to top under the action of the spring 33, the plurality of ratchet wheels 321 are propped against the side wall of the ventilation pipe a, the ratchet wheels 321 are attached to the ventilation pipe a to rotate, the ratchet wheels 321 move downwards relative to the ventilation pipe a, and finally the whole first clamp 34 is sleeved at the upper end of the ventilation pipe a; then, the piston rod of the first cylinder 44 is lifted, so that the first connecting rod 42 moves upwards, the first clamp 34 moves upwards, and due to the action of the spring 33, the ratchet wheels 321 can only rotate on the inner side wall of the sleeve from bottom to top, so that the plurality of ratchet wheels 321 prop against the side wall of the ventilation pipe a, the ratchet wheels 321 cannot rotate relative to the ventilation pipe a, and the ventilation pipe a is pulled up by one distance from the grain stack by the first clamp 34. Therefore, the piston rod of the first cylinder 44 is moved up and down continuously, and the first clamp 34 is used to intermittently pull the piston rod from the grain pile until the second clamp 35 is sleeved on the upper end of the vent pipe a.
After the second clamp 35 is sleeved at the upper end of the ventilation pipe a, due to the transmission of the warping plate 41, when the piston rod is lifted by the first cylinder 44, the second clamp 35 moves repeatedly one by one, the moving directions of the first clamp 34 and the second clamp are opposite, the first clamp 34 and the second clamp move repeatedly alternately one by one, and the first clamp 34 and the second clamp 35 are matched with each other like left and right hands, so that the ventilation pipe a moves upwards continuously and is pulled out of the grain stack.
When the first clamp 34 and the second clamp 35 approach the lower end of the ventilation pipe a and the ventilation pipe a is completely pulled out, the bottom plate 2 is moved up to the initial position by the second cylinder 13. At this time, the first gear 23 and the second gear 15 are engaged with each other.
The motor 16 is activated to flip the movable plate 22 upward by 100 ° to 120 °. At this time, the vent pipe a is obliquely arranged at a lower rear part and a higher front part, and due to the self weight of the vent pipe a, the vent pipe a slides out of the first clamp 34 and the second clamp 35 and falls into the collecting tank 10 of the vehicle body 1.
And circulating the steps, namely pulling out the ventilation pipes a from the grain pile one by one and collecting the ventilation pipes a in the collecting tank 10 in a centralized manner.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
