Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] In order to solve the technical problem of how to pick blueberries with different diameters in batches, the present utility model provides a blueberry picking head, which can adjust the distance between the first comb teeth 211 and the second comb teeth 221, and can adapt to the picking of blueberries with different diameters.

[0026] It should be noted that the blueberry picking head of the present utility model is used for but not limited to blueberry picking machines, etc. For the convenience of description, in the present utility model, only the case where the blueberry picking head is applied to a blueberry picking machine is taken as an example for description, and the principle of the blueberry picking head applied to other types of equipment is substantially the same as that applied to a blueberry picking machine, and will not be elaborated here one by one.

[0027] Please refer to Figure 1 , Figure 1 , which is a structural schematic diagram of the blueberry picking head in an embodiment of the present utility model. The blueberry picking head includes a base column 100 and a plurality of combing and harvesting assemblies 200 arranged circumferentially along the base column 100. The combing and harvesting assembly 200 includes a first fruit harvesting comb 210 and a second fruit harvesting comb 220. The first fruit harvesting comb 210 is installed on the base column 100, and the first fruit harvesting comb 210 has a plurality of first comb teeth 211 arranged axially along the base column 100. The second fruit harvesting comb 220 has a plurality of second comb teeth 221 arranged axially along the base column 100. The plurality of first comb teeth 211 and the plurality of second comb teeth 221 are arranged at intervals, and the second fruit harvesting comb 220 is slidably arranged along the axis of the base column on the base column and can stay at any position on its sliding track to adjust the distance between the first comb teeth 211 and the second comb teeth 221.

[0028] In this embodiment, the base column 100 is first installed on the blueberry picker, thereby driving the base column 100 to rotate, causing the first and second picking combs 210, 220 to rotate with the base column 100. Blueberries with a diameter greater than the distance between the first and second comb teeth 211, 221 are caught by the first and second comb teeth 211, 221, and are then picked. If it is necessary to pick blueberries with a smaller diameter, the relative position of the first and second combs 210, 220, and thus the distance between the first and second comb teeth 211, 221, can be adjusted to catch blueberries with smaller diameters, completing the picking process. The above-described blueberry picking head can adjust the distance between the first and second comb teeth 211, 221, allowing for batch picking of blueberries of different diameters.

[0029] In some embodiments, the base column 100 is provided with a plurality of guide grooves 110 corresponding one-to-one to the plurality of second fruit picking combs 220 , and the second fruit picking combs 220 are slidably disposed in the guide grooves 110 .

[0030] In this embodiment, under the guidance of the guide groove 110, the second fruit picking comb 220 slides along the length direction of the guide groove 110. At the same time, under the support of the bottom surface and side walls of the guide groove 110, the second fruit picking comb 220 has a stable sliding track.

[0031] In some embodiments, the combing and picking assembly 200 further includes a distance adjusting member 230 , which is mounted on the base column and is transmission-connected to the second fruit picking comb 220 to push the second fruit picking comb 220 to slide along the guide groove 110 .

[0032] In this embodiment, the distance adjusting member 230 is used to adjust the sliding movement of the base column in the guide groove 110 , thereby adjusting the relative position of the second fruit picking comb 220 and the first fruit picking comb 210 .

[0033] Any embodiment is feasible as long as the relative position between the second fruit picking comb 220 and the first fruit picking comb 210 can be adjusted. In some embodiments, the distance adjusting member 230 includes a bolt 231. The base column 100 is provided with a screw hole (not shown in the figure). The bolt 231 is screwed into the screw hole (not shown in the figure), and one end of the bolt 231 is rotatably connected to the second fruit picking comb 220.

[0034] In this embodiment, the bolt 231 can be rotated to move along the length direction of the guide groove 110 , thereby pushing the second fruit picking comb 220 to slide relative to the guide groove 110 .

[0035] In some of these embodiments, the first fruit combing member 210 is provided with a plurality of mating holes 212 corresponding to the plurality of second comb teeth 221 one by one. The first fruit combing member 210 covers the opening of the guiding groove 110, and the second comb teeth 221 pass through the mating holes 212, and the second comb teeth 221 can move slightly within the mating holes 212.

[0036] In this embodiment, by making the second comb teeth 221 pass through the mating holes 212, the first comb teeth 211 and the second comb teeth 221 can be arranged at intervals, and the second comb teeth 221 can move slightly within the mating holes 212 to facilitate adjusting the distance between the second comb teeth 221 and the first comb teeth 211.

[0037] In some of these embodiments, the blueberry picking head further includes an anti-reverse rotation assembly 300. The anti-reverse rotation assembly 300 includes a plurality of elastic key members 310 arranged along the axial direction of the base column 100. The base column 100 is provided with a plurality of receiving grooves 120 corresponding to the plurality of elastic key members 310 one by one. The elastic key members 310 are movably embedded in the receiving grooves 120. The elastic key members 310 have an elastic force that causes a part of them to protrude from the receiving grooves 120, and one side of the key members has a guiding wedge surface.

[0038] In this embodiment, the elastic key members 310 cooperate with the external frame. When the base column 100 rotates in the forward direction, the guiding wedge surface will press against the frame, thereby overcoming the elastic force of the elastic key members 310, and then causing the elastic key members 310 to be completely received in the receiving grooves 120, so that the base column 100 can rotate smoothly in the forward direction. When the base column 100 rotates in the reverse direction, the elastic key members 310 will press against the frame, and then can hinder the base column 100 from rotating in the reverse direction.

[0039] Based on the above embodiments, in some of these embodiments, the elastic key member 310 includes a spring 311 and a locking block 312. The locking block 312 is slidably embedded in the receiving groove 120, and the locking block 312 has a guiding wedge surface. One end of the spring 311 is connected to the locking block 312, and the other end thereof is connected to the base column 100.

[0040] In some of these embodiments, the base column 100 is axially provided with a rotating shaft hole 130.

[0041] In this embodiment, the rotating shaft hole 130 can be sleeved on the outer periphery of the rotating shaft, so that the base column 100 can rotate with the rotating shaft.

[0042] In some of these embodiments, the surface of the first comb teeth 211 has first anti-slip lines, and the surface of the second comb teeth 221 has second anti-slip lines.

[0043] In this embodiment, since the first comb teeth 211 and the second comb teeth 221 respectively have the first anti-slip lines and the second anti-slip lines, the friction between the first comb teeth 211 and the second comb teeth 221 is increased.

[0044] In addition, the present utility model also provides a blueberry picking machine, which includes the above-mentioned blueberry picking head.

[0045] For a better understanding of the present utility model, the following will Figures 1 to 3 describe the technical solution of the present utility model in detail:

[0046] First, install the base column 100 on the blueberry picking machine, so as to drive the base column 100 to rotate. As a result, the first fruit picking comb 210 and the second fruit picking comb 220 rotate along with the base column 100. Blueberries with a diameter larger than the distance between the first comb teeth 211 and the second comb teeth 221 will be caught by the first comb teeth 211 and the second comb teeth 221, and then the blueberries are picked. If it is necessary to pick blueberries with a smaller diameter, the base column is adjusted to slide in the guiding groove 110 through the distance adjusting member 230, so as to adjust the relative positions of the second fruit picking comb 220 and the first fruit picking comb 210, and thus the distance between the first comb teeth 211 and the second comb teeth 221, so that blueberries with a smaller diameter can be caught, completing the picking of blueberries with a smaller diameter. The above-mentioned blueberry picking head can adjust the distance between the first comb teeth 211 and the second comb teeth 221, and thus can pick blueberries with different diameters in batches.

[0047] The specific implementation manners of the present utility model described above do not constitute a limitation to the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
