The other end of the fixed pipe 41 is connected, and the first fixed pipe 41 and the second fixed pipe 42 are connected in a V shape as a whole; the first fixed pipe 41 and the second fixed pipe 42 are oppositely provided with an electromagnet 62; the telescopic rod 11 faces away from the One end of opening and closing device 4 is provided with power supply 13 and control switch 14, is provided with several wires in telescoping rod 11, and the driving motor on the first roller 51 is connected in series with power supply 13 and control switch 14, and the driving motor of first roller 51, The second roller 52 drive motor and the electromagnet 62 are connected in parallel. When the control switch 14 is closed, the electromagnet 62 is energized, and the first fixed tube 41 and the second fixed tube 42 are close to each other, and the two drive motors drive the first fixed tube 41 and the second fixed tube 42 respectively. Roller 51 and second roller 52 rotate; Collection device comprises several support rods 21 and support 23 that are connected to each other, and several support rods 23 are erected on the ground and arrange around trunk, and one end of support rod 21 is connected with support 23, and the other end is connected to support 23. The downward inclination is offset against the tree trunk, and a tarpaulin 22 is arranged between two adjacent support rods 21. There are several fixing rings 221, and the supporting rods 21 are provided with hooks 211. The fixing rings 221 and the hanging hooks 211 are arranged oppositely. ; When the hickory nuts fell from the tree, the hickory nuts fell onto the tarpaulin 22 . When carrying out hickory picking, there is no need to knock the branches. When people are picking hickory, they build up the support 23, the support rod 21 and the tarpaulin 22, so that a plurality of supports 23 and the support rod 21 surround the walnut tree. Then the tarpaulin 22 is connected with the support rod 21 through the fixing ring 221 and the hook 211 . Simultaneously, one end of the support rod 21 that is against the trunk is slightly inclined downward, so that the entire surface surrounded is in an inverted umbrella shape. Place the collection bag for collecting hickory nut fruit below the bottom of the inclined end of the tarpaulin 22 below the trunk, because the support bar 21 is inclined to set, the tarpaulin 22 is also inclined to be arranged, and after the hickory nuts fall on the tarpaulin 22 , the hickory slides down the inclination direction of the tarpaulin 22 and is drawn into the collection bag arranged below. When the hickory nuts in the collection bag are full, the collection bag can be lifted directly, which is very fast. There will be no people picking pecans on the tree. The pecans fall everywhere on the ground. After people pick the pecans, they need to collect the pecans on the ground. It takes time to gather pecans from the ground. And the existence of collecting device has just avoided above-mentioned deficiency. Before the control power supply 13 is closed, adjust the position and the direction of the telescopic rod 11, so that the long hickory branch is between the first roller 51 and the second roller 52, when the control switch 14 is closed, the opening and closing device 4 The first fixed pipe 41 and the second fixed pipe 42 are close to each other and make the first roller 51 and the second roller 52 clamp the branch because the electromagnet 62 is energized to generate magnetic force, and the first roller 51 and the second roller 52 are also caused by the same time. Rolling occurs when power is applied. At this time, the telescopic rod 11 is gradually pushed, so that the first roller 51 and the second roller 52 are displaced, and rolling occurs while the displacement occurs. The hickory on the branch is clamped and pushed and under the action of the shearing force produced by the rolling of the first roller 51 and the second roller 52, the hickory of a branch can fall quickly and fall to the tarpaulin 22, and finally slides into the collection bag, improving efficiency. Like this, people just needn't knock on tree branch, make can influence tree branch, influence the harvest of the coming year. Simultaneously, when moving telescopic pole 11, because first roller 51 and second roller 52 roll have a shearing force to hickory nut, make people need not spend a lot of effort to make telescopic pole 11 pick hickory nut, greatly reduce The force used by the human hand. At the same time, due to the existence of the telescopic rod 11, people do not need to climb to hickory nuts and branches to pick hickory nuts, which greatly reduces accidents.

As an improved specific embodiment, the opposite side of the first fixed tube 41 and the second fixed tube 42 is provided with a return spring 61, one end of the return spring 61 is connected with the first fixed tube 41, and the other end is connected with the second fixed tube. 42 connection, when the control switch 14 is closed, the first fixed tube 41 and the second fixed tube 42 are close to each other and the return spring 61 is compressed, when the control switch 14 is turned off, the return spring 61 resets and the first fixed tube 41 and the second fixed tube The two fixing tubes 42 are separated from each other under the action of elastic force. When picking pecans, people extend the two far away by the telescopic rod 11 and make the branches in the first roller 51 and the second roller 52 . When the telescopic rod 11 extends the two to the branches, since the connection between the first fixed tube 41 and the second fixed tube 42 is hinged, the first fixed tube 41 and the second fixed tube 42 will appear close to each other. , so that the first roller 51 and the second roller 52 are also close to each other, it is difficult to make branches enter between the first roller 51 and the second roller 52, people need to shake the telescopic rod 11 to make the first fixed pipe 41 and the second fixed pipe 42 Separated so that the first roller 51 and the second roller 52 move away from each other, allowing branches to enter between the two. But shaking the telescopic rod 11 from time to time can make the staff feel tired, and at the same time, if people climb to the tree and wave the telescopic rod 11, it is easy for the picking personnel to lose their center of gravity and accidentally fall, causing casualties. The presence of the return spring 61 can make the first fixed pipe 41 and the second fixed pipe 42 be V-shaped when the control switch 14 is not closed, so as to ensure that branches can enter between the first roller 51 and the second roller 52 smoothly. When the control switch 14 is closed, the magnetic force generated by the electromagnet 62 makes the first fixed tube 41 and the second fixed tube 42 attract each other. The magnetic force is greater than the elastic force of the return spring 61, so that the first rollers 51 can approach each other to hold the branches, and roll to pick the hickory nuts. But when the control switch 14 was disconnected, the magnetic force produced by the electromagnet 62 disappeared, and the elastic force of the back-moving spring 61 made the first fixed pipe 41 and the second fixed pipe 42 move away from each other, so that the first roller 51 and the second roller 52 moved away from each other and Able to detach from the branch and go to the next branch to pick.
