[0041] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0042] Example 1

[0043] An apple netting device comprises three parts: a sorting unit, a net feeding unit and a net supporting unit.

[0044] See also Figure 1 and Figure 2 The sorting unit is provided with a rotating shaft 1, a fixed shaft 2, a driving motor 3, a funnel 4, and a pipe 5. The rotating shaft 1 rotates counterclockwise in the left-view direction. There are four rotating shafts 1 in total. The four rotating shafts 1 are at different positions and have different spacings. The distance between each rotating shaft on the left side is 80 mm, and the distance between each rotating shaft 1 on the right side is 30 mm. The driving motor 3 provides power for the rotating shaft 1 to rotate.

[0045] See also Figure 3 and Figure 4 The net feeding unit includes a first rack 6, a chassis 7, a steering gear 8, a first gear 9, a friction wheel 10, a servo motor 11, and a copper bar 12. The chassis 7 is provided with a first rack 6 and a first gear 9. The steering gear 8 drives the first gear 9 to rotate to control the up and down movement of the first rack 6 meshed with the first gear 9. Below the first rack 6 is a copper bar 12 at the end, which can be used to cut the mesh bag after being electrically heated.

[0046] See also Figure 5 , Figure 6and Figure 7 The net supporting unit includes a base 13, a flexible mechanical arm 14, a sleeve 15, a clamp 16, a connecting rod mechanism 17, and a second gear assembly 18. The clamp 16 is a six-claw structure, consisting of six identical cones, each of which has a bottom diameter of 5 mm and a height of 40 mm, and the clamp has an inclination angle of 86°. The clamp 16 is connected to the connecting rod mechanism 17, and the connecting rod mechanism 17 cooperates with the second gear assembly 18. The clamp 16, the connecting rod mechanism 17 and the second rack 20 cooperate with a crank rocker mechanism. There is a retaining ring on the outside of the sleeve 15 for fixing the steering gear 8 and the second gear assembly 18. A controller is also installed on the fixed shaft 2, and the controller is electrically connected to the drive motor, the FET steering gear and the flexible mechanical arm 14 respectively, and the controller, the drive motor, the FET steering gear and the flexible mechanical arm 14 are all externally connected to a power supply.

[0047] Example 2

[0048] Except for the following contents, the rest of the contents are the same as those in Example 1.

[0049] There are three funnels 4 for collecting apples of different sizes, and the upper diameter of each funnel is 475 mm, and the lower diameter is 100 mm. There are three pipes, each of which has a vertical length of 450 mm and a diagonal length of 250 mm.

[0050] Example 3

[0051] Except for the following contents, the rest of the contents are the same as those in Example 1.

[0052] There are two groups of friction wheels 10, both of which are powered by a servo motor 11 to rotate. The sleeve 15 is a hollow rectangular parallelepiped with a circular channel in the middle for apples to enter.

[0053] The working principle of the device of the present invention is as follows:

[0054] During operation, apples are placed in the sorting unit, which is similar in appearance to a conveyor belt and includes four uninterrupted rotating shafts 1, which rotate under the drive of a driving motor 3. After the apples enter, they fall at different positions of the rotating shafts 1 according to the diameters of the apples, and fall into the funnel 4 below. A pipe 5 is connected below the funnel 4. After the apples roll into the funnel 4, they follow the pipe 5 into the supporting net mechanism.

[0055] While the sorting mechanism is working, the net feeding mechanism also starts working. There are two groups of friction wheels 10. The mesh bag is fed in by the first group of friction wheels 10 and sent out by the second group of friction wheels 10. There is a distance of 100mm between the two groups of friction wheels 10. The controller controls the start and stop of the friction wheels 10 through the signal feedback of the number of rotations of the first and second groups of friction wheels 10. When the required length of the mesh bag reaches the set standard, the controller feedback signal controls the FET steering gear to energize and heat the copper strip 12 at the lower end of the first rack 6, and controls the friction wheel 10 to stop rotating, and controls the steering gear 8 to drive the first gear 9, control the up and down movement of the first rack 6 meshing with the first gear 9, and cut the mesh bag through the heated copper strip 12. The mesh bag is cut by thermal cutting. The advantages of this cutting method are convenient cutting, low cost, and neat cutting.

[0056] After the mesh bag is cut, the controller controls the second set of friction wheels to work and send out the cut mesh bag. At the same time, the net supporting mechanism starts to work, controls the flexible mechanical arm 14 to rotate 45 degrees counterclockwise with the base 13 as the rotation center, and sends the tightened clamping claw 16 into the mesh bag. The clamping claw 16 is connected to the connecting rod mechanism 17, and the connecting rod mechanism 17 cooperates with the gear rack module 18. The clamping claw 16, the connecting rod mechanism 17 and the rack 20 are coordinated by a crank rocker mechanism. After the clamping jaw 16 enters the mesh bag, the servo controls the second gear assembly 18, and the servo fixed by the retaining ring starts to rotate. The second gear 19 is driven by the servo, and the second rack 20 meshing with the second gear 19 moves up and down. The second rack 20 is connected to the connecting rod mechanism 17, and the connecting rod mechanism 17 is connected to the clamping jaw 16. When the second rack 20 moves, the connecting rod mechanism 17 transmits upward, driving the tightened clamping jaw 16 to open outward by 45° to ensure that the mesh bag of sufficient diameter is opened, so that the apples can enter the mesh bag smoothly.

[0057] After the clamping claw 16 opens the mesh bag, the flexible mechanical arm 14 rotates 45°, and the flexible mechanical arm 14 automatically rotates and adjusts to align the sleeve 15 of the mesh supporting mechanism with the pipe 5 of the sorting mechanism. The fixed rail of the sleeve 15 cooperates with the sorting mechanism, so that the circular channel in the sleeve 15 is embedded with the pipe 5, which is convenient for the apple to fall into. The front clamping claw 16 of the flexible mechanical arm 14 can open the mesh bag, and then the clamping claw 16 grabs the apple, and the bagging function of the apple can be realized. The mesh supporting unit is connected to the pipe 5 as a whole, and the sleeve 5 of the mesh supporting unit is opened. The apple uses gravity to smoothly pass through the sleeve 15 and roll into the clamping claw 16, and finally falls into the mesh bag and falls into the packaging box together.

[0058] It should be noted that the servo used in this embodiment is a FET servo, and the funnel 4 is made of low-density polyethylene material, which can protect the apples from being damaged due to gravity impact when they fall.

[0059] The above contents are only for explaining the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the claims of the present invention.
