[0028] It should be understood that terms such as "having", "including", and "comprising" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0029] It should be noted that in the description of the present utility model, the orientation or positional relationships indicated by terms such as "horizontal", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the attached drawings. It is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0030] It should be noted that the control methods in the following implementation schemes are all conventional methods without special instructions, and the device structures can be obtained from commercial channels without special instructions.

[0031] As Figures 1 to 4 , the present utility model provides a litchi picking device, including:

[0032] Shearing mechanism 1;

[0033] The picking and receiving mechanism 2, which is detachably connected to the shearing mechanism 1, includes: a fixing ring 200, a litchi transmission member 210, and a plurality of buffer strips 220. The upper end of the litchi transmission member 210 is provided with a first opening 211, and the lower end is provided with a second opening 212. A transmission cavity 230 is provided between the first opening 211 and the second opening 212. A fixing cavity 213 is provided on the picking and receiving mechanism 2 near the first opening 211. The fixing ring 200 is arranged in the fixing cavity 213. A plurality of buffer strips 220 are arranged at intervals on the left and right sides inside the transmission cavity 230. Among them, the length of the overlapping area between adjacent buffer strips 220 is 1 / 5 to 1 / 4 of the length of each buffer strip 220.

[0034] In the above implementation, as Figure 1 and 4 shown, the buffer strip 220 is supported by a flexible material. Under the action of the gravity of the litchi, it bends downward to transmit the litchi level by level into the packing box placed on the ground. When the litchi sheared by the shearing mechanism 1 falls into the transmission cavity 230 from the first opening 211, during the free fall of the litchi, through the buffering effect of the plurality of buffer strips 220, the problem that the litchi is easily damaged during the landing process is reduced. At the same time, the problem of repeatedly pouring the litchi picking device into the packing box in the prior art is avoided, and the litchi picking efficiency is improved. The litchi transmission member 210 can be a barrel structure made of a flexible material or a rigid material. In order to reduce the weight of the picking device, it is preferably made of a flexible material, such as a structure similar to a waterproof woven bag. The plurality of buffer strips 220 can be fixed by tying them to the litchi transmission member 210 with ropes. The fixing cavity 213 is a hemming structure provided at the first opening 211. The fixing ring 200 is a metal ring, such as an iron ring. The fixing ring 200 is wrapped and fixed at the first opening 211 through the fixing cavity 213, so that the fixing ring 200 supports and opens the first opening 211 at the upper end of the litchi transmission member 210, facilitating the picked litchi to fall into the transmission cavity 230, and at the same time making the entire litchi transmission member 210 in a downward hanging state. By the length of the overlapping area between adjacent buffer strips 220 being 1 / 5 to 1 / 4 of the length of each buffer strip 220, the buffering effect of the freely falling litchi can be achieved, and when the upper buffer strip 220 bends downward, it will not overlap with the adjacent buffer strip 220 to make the litchi fall smoothly.

[0035] In another embodiment, the shearing mechanism 1 includes: a shearing head 100, a connecting member 110, and an operating member 120. The shearing head 100 is disposed at the upper end of the connecting member 110, and the operating member 120 is disposed at the lower end of the connecting member 110. Among them, the shearing head 100 includes: a fixed shearing blade 101 and a movable shearing blade 102. The connecting member 110 includes a sleeve 111 and a transmission member 112. The operating member 120 includes a fixed grip 121 and a movable control member 122. The transmission member 112 is disposed within the sleeve 111. The movable control member 122 is connected to the movable shearing blade 102 through the transmission member 112 to drive the movable shearing blade 102 to move towards the fixed shearing blade 101 to clamp the branch at the litchi position, and the litchi is sheared by clamping with the fixed shearing blade 101 and the movable shearing blade 102.

[0036] In the above embodiment, as Figure 2 shown, the picker holds the operating member 120 by hand, and moves the movable control member 122 towards the fixed grip 121 with the thumb. The transmission member 112 is connected to the movable shearing blade 102. The holding movement force drives the transmission member 112 to pull the movable shearing blade 102 to rotate towards the fixed shearing blade 101 to clamp the branch at the litchi fruit position, and the branch is cut off by the blades on the opposite surfaces of the fixed shearing blade 101 and the movable shearing blade 102 to achieve the picking of litchi. After one picking is completed, the picker loosens the movable control member 122 and returns it to its original position, and repeats the above actions to continue the next litchi picking. It is convenient to operate and saves time and effort.

[0037] In another embodiment, the litchi picking device further includes:

[0038] a support mechanism 3, which is configured on the picker's body; the support structure 3 includes: a waistband 300 and a support platform 310.

One end of the support rod 330 is supported and fixed at the bottom of the support cavity 320, and the other end supports and fixes the clamping member 340, and the clamping member 340 clamps the connecting member 110.

[0039] In the above embodiment, as Figure 3As shown, when picking lychees, the picker supports the support structure 3 on the waist through the adhesion of the magic mother sticker 301 and the magic son sticker 302 in the waistband 300. At this time, the support platform 310 is located at the chest position directly in front of the picker. The picker holds the connecting member 110 in the shearing mechanism 1 through the clamping member 340, avoiding problems such as arm soreness and fatigue caused by the picker holding the shearing structure with the arm for a long time, reducing the working intensity of the picker, and improving the picking efficiency. Among them, the material structure of the waistband 300 can be set to be similar to the structure of a baby's lumbar stool. The structure of the support platform 310 is also similar to the position where a baby sits on a lumbar stool, but it is a rigid structure around, with a hollow in the middle as the support cavity 320. A support member is provided at the bottom of the support cavity 320, and a support rod 330 can be inserted into the middle of the support member. The support rod 330 and the clamping member 340 are integrally formed. The support rod 330 is made of a rigid material, such as wood or metal.

One end of the hanging member 4 can be detachably connected to the fixing ring 200 by clamping, so that the picking and receiving structure 2 is convenient to replace. The other end is hung into the hanging hole 130 provided in the upper part of the shearing mechanism 1 by hanging.

[0043] In another embodiment, the buffer strip 220 is a hollow structure, and the buffer strip 220 is a polyethylene hollow foam strip. The buffer strip 220 is made of the flexible material polyethylene hollow foam, with low practical cost and safe and non-toxic.

[0044] In another embodiment, one end of the hanging member 4 is a connecting rod 400 and the other end is a hook-shaped structure 410. The connecting rod 400 is clamped on the fixing ring 200 in the picking and receiving mechanism 2, and the hook-shaped structure 410 is hung in the hanging hole 130 provided in the upper part of the shearing mechanism 1, which is convenient for disassembly, simple in operation and convenient for replacement.
