Picking fruits growing on tall fruit trees has always been a difficult problem for fruit farmers. The traditional picking method is to pick fruits by setting up ladders or climbing trees. This picking method has the disadvantages of high labor intensity, low efficiency, and unsafety. , there are various fruit pickers on the market for picking fruits from fruit trees. Most of these fruit pickers use conventional scissor-shaped props. But the higher the fruit tree, the higher the fruit-hanging position, the more difficult it is to align the V-shaped blade of the scissors with the fruit stem, especially the fruit stems of some fruits are very tough, and it is difficult to cut off the fruit stem once, so it needs to be re-aligned , and during the cutting process, the fruit pedicle is easy to slide along the scissors blade, making the cutting effect not good.

Detailed ways

In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

As shown in Figures 1 to 5 and 7, the first embodiment of a fruit picker according to the present invention includes a hollow strut 1, and the top of the strut 1 passes through a second hollow connected to the strut 1. The pipe 3 is equipped with a shearing device, and the bottom of the strut 1 is provided with a non-slip handle 4, and the position of the strut 1 close to the handle 4 is provided with a second winding wheel 6, and the second winding wheel 6 is pulled by a second pulley. The rope 8 controls the shearing device, and the bottom of the shearing device is equipped with a collection net 9 through the first hollow tube 2, and the position of the strut 1 near the handle 4 is provided with a first winding wheel 5, and the collection net 9 A contraction ring 10 is provided at the network port, and the contraction ring 10 is formed by bending an elastic strip. One end of the elastic strip is fixed on the first hollow tube 2, and the other end extends into the first hollow tube 2. One end in the first hollow tube 2 is provided with a first connecting ring 11, and the first connecting ring 11 is connected with the first reel 5 through the first stay cord 7, and the collecting net 9 is made of a common mesh bag. The elastic strip passes through the mesh of the collection net to form a contraction ring. When the first reel 5 takes up the wire, the first stay cord 7 tightens the contraction ring 10 thereupon, and the network port of the collection net 9 is also tightened. The fruit pedicel is limited in the shear range of the shearing device. After the first winding wheel 5 is released, under the effect of the elastic force of the shrinkage mouth ring 10 itself, the 9 mesh openings of the collection net are opened automatically.

The end of the first hollow tube 2 away from the strut 1 is provided with an annular limiting piece 12 , and the outer diameter of the first connecting ring 11 is larger than the inner diameter of the limiting piece 12 .

The second hollow tube 3 is provided with a blocking piece 13, and the shearing device includes a scissors blade 14 and a slider 15. On the other side, the end of the slider 15 away from the retainer 13 is provided with a mounting groove 16, the scissors 14 are hinged in the mounting groove 16 through the scissors shaft, and the end of the second hollow tube 3 away from the strut 1 is provided with a bracket 17, the Roller 18 is installed on the support 17, and described roller 18 contacts with the knife back of scissors blade 14, and slide block 15 is connected with catch 13 by spring 19 toward the end face of catch 13, and is provided with second connecting ring 20 on this end face , the second connecting ring 20 is connected to the second stay cord 8, and the second stay cord 8 passes through the catch 13 and is connected to the second reel 6, as shown in Figures 2 to 4, the scissors 14 are Obtuse triangular shape with rounded corners. When the second reel 6 tightens the second pull cord 8, the slider 15 is driven to slide towards the blocking piece 13. The scissors 14 are squeezed by the roller 18 to gather and cut Fruit pedicle, when cutting finished, unclamp the second winding wheel 6, under the effect of spring 19, the cutting device resets.

In order to avoid the need to take back the strut 1 to take the fruit in the collection net 9 after picking the fruit each time, a transmission cloth tube 22 is connected to the bottom of the collection net 9, and the end of the transmission cloth tube 22 away from the collection net 9 is arranged on the Close to the position of the handle 4, the picked fruit can reach the vicinity of the handle 4 along the transmission cloth tube 22, which is convenient for collection. In order to buffer the falling speed of the fruit, the length of the transmission cloth tube 22 is slightly longer than that of the support rod 1. Under the action of gravity, The last section of the transmission cloth tube 22 is relatively gentle, which can effectively reduce the transmission speed of the fruit.

The structure of the second embodiment of a fruit picker according to the present invention is basically the same as that of the first embodiment, and the difference is that the shearing device includes a mounting plate 21 and a scissor blade 14 ′, and the mounting plate 21 It is arranged at the end of the second hollow tube 3 away from the strut 1, the scissors 14' are hinged on the mounting plate 21 through the scissors shaft, and the scissors 14' near the end of the second hollow tube 3 are connected by a spring 19', and The end of the scissors 14 ′ close to the second hollow tube 3 is connected to the second reel 6 through the second pull cord 8 .

In the working process of the present invention, the fruit to be picked is put into the collection net 9, the fruit pedicle is aligned in the V-shaped cutting edge of the shearing device, and then the first stay rope 7 is tightened by the first winding wheel 5 to tighten the The 9 mesh openings of the collection net limit the fruit pedicles within the shearing range of the shearing device, then pull the second stay rope 8 through the second winding wheel 6, and close the scissor blades to cut the fruit pedicles. After the 9 nets are tightened, the range of motion of the fruit pedicles is limited. Therefore, during the cutting process, the fruit pedicles will not slip out of the cutting range, which effectively improves the picking efficiency. Here, in order to ensure that the fruit is inserted into the collection net 9, the The kind of fruit to be picked determines the relative size of the collection net 9 net openings and the shearing device, and the distance between the collection net 9 and the shearing device, as long as the shearing device does not hinder the fruit from entering the collection net 9, of course the present invention The strut 1 can also be set as a telescopic rod.

The technical solution of the present invention has exemplarily described the invention above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned method, as long as various insubstantial improvements made by the method concept and technical solution of the present invention are adopted, Or directly applying the concept and technical solution of the invention to other occasions without improvement is within the protection scope of the present invention.
