Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Depend on Figures 1 to 3 A clamping and conveying device of a self-propelled leafy vegetable orderly harvester is provided, comprising a frame 1, a support frame 2, two support seats 21, two lower conveying wheels 3, two tensioning mechanisms, two lower driven wheels 32, two lower conveying belts 31 and two adjusting mechanisms.

[0047] A conveying system is composed of a support frame 2, two support seats 21, two lower conveying wheels 3, two tensioning mechanisms, two lower driven wheels 32, two lower conveying belts 31 and two adjustment mechanisms. The conveying system is provided with five groups. The five conveying systems cooperate with each other in pairs and can convey four rows of leafy vegetables at the same time.

[0048] The structure of one of the conveying systems is described in detail below:

[0049] Depend on Figures 1 to 3 It is shown that the support frame 2 is installed at the front end of the frame 1 at an angle downward, and two support seats 21 are respectively installed at the top of the front ends of the two support frames 2. The two lower conveying wheels 3 are installed on the top of the support seats 21 through bearings, and the bearings facilitate the rotation of the lower conveying wheels 3.

[0050] Depend on Figures 5 and 6 It is shown that the two tensioning mechanisms are both installed at the front end of the support frame 2 , and the tensioning mechanisms include a bearing seat 33 , a moving plate 34 , a spring 35 and a lower driven wheel mounting seat 36 .

[0051] The bearing seat 33 is installed on the side of the support frame 2 away from the lower conveying wheel 3. The bearing seat 33 cooperates with the support frame 2 to form a rectangular sliding groove. The movable plate 34 is slidably installed in the sliding groove. The spring 35 is installed between the bearing seat 33 and the movable plate 34. The lower driven wheel mounting seat 36 is installed on the end of the movable plate 34 away from the spring 35. The lower driven wheel 32 is rotatably installed on one side of the lower driven wheel mounting seat 36. The lower conveyor belt 31 is wound and installed on the periphery of the lower conveying wheel 3 and the lower driven wheel 32. The spring 35 presses against the movable plate 34. The spring 35 will give a thrust to the movable plate 34, so that the lower driven wheel 32 tightly pulls one end of the lower conveyor belt 31, thereby ensuring the tension of the lower conveyor belt 31 and preventing the lower conveyor belt 31 from falling off from the periphery of the lower conveying wheel 3 and the lower driven wheel 32.

[0052] Depend on Figures 4 to 6 It is shown that the two adjustment mechanisms are respectively installed on the top of the support frame 2 and the two moving plates 34 , and the adjustment mechanisms include two rotating rods 7 , two sector gears 71 , two eccentric wheels 72 and two knobs 73 .

[0053] The two adjusting mechanisms respectively adjust the top end and the bottom end of the lower conveyor belt 31 .

[0054] The two adjustment mechanisms are provided with four rotating rods 7 in total, two of which are symmetrically rotatably mounted on the top of the support frame 2, and the other two rotating rods 7 are symmetrically rotatably mounted on the top of the two moving plates 34; two sector gears 71 are symmetrically mounted on the periphery of the top of the two rotating rods 7, the two sector gears 71 are meshed with each other, and two eccentric wheels 72 are respectively arranged at the bottom of the two rotating rods 7, the protruding ends of the two eccentric wheels 72 are facing back to back, and the protruding ends of the two eccentric wheels 72 are respectively abutted against the two lower conveyor belts 31. On the inner walls on both sides of the back, two knobs 73 are respectively arranged on the top of the two rotating rods 7. By turning any one of the knobs 73, the knob 73 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the eccentric wheel 72 at the bottom to rotate. At the same time, the rotating rod 7 drives the fan gear 71 installed on the top to rotate, and the fan gear 71 drives another fan gear 71 to rotate, so that the other rotating rod 7 drives the eccentric wheel 72 to rotate. At this time, the two eccentric wheels 72 are in opposite directions, and the two eccentric wheels 72 respectively push against the two lower conveyor belts 31 to expand to both sides.

[0055] Specifically, the two eccentric wheels 72 of this group push the two lower conveyor belts 31 to expand outward, and the two eccentric wheels 72 of the other group also push the two lower conveyor belts 31 to expand outward, so that the lower conveyor belts 31 of this group and the adjacent lower conveyor belts 31 of another group are close to each other, thereby adjusting the distance between the two lower conveyor belts 31.

[0056] Depend on Figure 3 and Figure 7 It is shown that two sets of middle conveying mechanisms cooperating with the lower conveying wheels 3 are also installed in the middle of the frame 1.

[0057] Each set of the middle conveying mechanism includes two bearing plates 45, two middle conveying wheels 4, two positioning seats 42, two middle conveying belts 41, two middle driven wheels 43, four elastic wheels 44 and auxiliary components.

[0058] The two carrying plates 45 are respectively installed on the top of the two supporting frames 2, the two middle conveying wheels 4 are rotatably installed on the bottom of the two carrying plates 45 through bearings, and the bottoms of the two middle conveying wheels 4 are respectively installed on the top of two of the lower conveying wheels 3 through universal shafts, the two positioning seats 42 are respectively installed on the top of the two supporting seats 21, the four elastic wheels 44 are respectively rotatably installed in the middle of the top of the two positioning seats 42, the two middle driven wheels 43 are respectively installed on the top of the two positioning seats 42, the middle conveying belt 41 is wound and installed on the periphery of the middle conveying wheel 4, the middle driven wheel 43 and the two elastic wheels 44, and a conveying structure on one side is formed by a positioning seat 42, a middle conveying wheel 4, a middle conveying belt 41, a middle driven wheel 43 and two elastic wheels 44.

[0059] The middle conveyor belt 41 is made of soft material to avoid damaging the leafy vegetables when clamping and conveying the leafy vegetables.

[0060] Next, it is explained that the two tension wheels 44 are mounted on the positioning seat 42 by bolts. The positions of the two tension wheels 44 can be adjusted by loosening the bolts, thereby changing the tension of the middle conveyor belt 41.

[0061] Depend on Figure 3 and Figure 7 It is shown that there are two groups of auxiliary components, which are installed on the top of the support seat 21. The auxiliary components include two driving wheels 46, a linkage wheel 47, two tensioning wheels 48 and four conveying ropes 49.

[0062] The bottoms of the two driving wheels 46 are respectively installed on the tops of two of the lower conveying wheels 3 through universal shafts, the two tensioning wheels 48 are installed on the top of the support seat 21, and the interlocking wheel 47 is installed on the front end of the top of the support seat 21. The four conveying ropes 49 are sequentially wound and installed on the periphery of the two driving wheels 46, the interlocking wheel 47 and the two tensioning wheels 48. The four conveying ropes 49 cooperate with the two middle conveyor belts 41 to form two middle conveying channels for clamping and conveying leafy vegetables. The two middle conveying channels have two vegetable inlets, but only one vegetable outlet.

[0063] Specifically, the positioning seat 42 is composed of two plates, which are installed together by bolts. The position of the two plates can be adjusted by loosening the bolts, thereby facilitating the adjustment of the distance between the middle conveyor belt 41 and the conveyor rope 49 to adapt to different leafy vegetables.

[0064] Depend on Figure 3 and Figure 8 It is shown that an upper conveying mechanism matching with the middle driven wheel 43 is installed on one side of the positioning seat 42, and the upper conveying mechanism includes two support rods 52, an upper conveying wheel 5, two upper driven wheel mounting seats 53, two upper driven wheels 54, two upper conveying belts 51 and a moving assembly.

[0065] The two support rods 52 are respectively installed on one side of the two positioning seats 42, the two upper conveying wheels 5 are respectively installed on the bottom of the two middle driven wheels 43 through universal shafts, the two upper driven wheel mounting seats 53 are respectively installed on one end of the two support rods 52 away from the positioning seat 42, the two upper driven wheels 54 are rotatably installed on one side of the two upper driven wheel mounting seats 53, the upper conveyor belt 51 is wound and installed on the periphery of the upper conveying wheel 5 and the upper driven wheel 54, and the two upper conveyor belts 51 clamp the leafy vegetables.

[0066] The four upper conveyor belts 51 are inclined inwardly and convert the leafy vegetables in a vertical state into a flat state during transportation.

[0067] In summary, the ten lower conveyor belts 31 cooperate with each other to form four lower conveying channels; the four middle conveyor belts 41 and the eight conveyor ropes 49 form four middle conveying channels, but the tops of the four middle conveying channels cooperate to form two discharge ends; the four upper conveyor belts 51 cooperate to form two upper conveying channels.

[0068] The whole vegetable harvesting process is that the leafy vegetables enter the four lower conveying channels and are transported upward, then enter the four middle conveying channels from the lower conveying channels, and then are transported by the four middle conveying channels to gather into two ridges of leafy vegetables, and then enter the upper conveying channel.

[0069] Depend on Figures 8 to 9 It is shown that the moving assembly is installed at the bottom of the support rod 52 , and the moving assembly includes a fixing block 8 , a screw rod 81 and two nuts 82 .

[0070] The fixing block 8 is installed at the bottom of the support rod 52, the screw 81 is installed at the bottom of the upper driven wheel mounting seat 53, and two nuts 82 are threadedly installed on the periphery of the screw 81, and the two nuts 82 are respectively abutted against the two sides of the fixing block 8. When the nuts 82 are turned, the screw 81 will move due to the limitation of the fixing block 8, and the screw 81 drives the upper driven wheel mounting seat 53 to move, thereby changing the distance between the upper conveying wheel 5 and the upper driven wheel 54, thereby ensuring the tension of the upper conveyor belt 51.

[0071] Specifically, a rotating rod 7, an eccentric wheel 72 and a knob 73 structure can also be installed on the support rod 52. The rotating rod 7 is rotatably installed on the top of the support rod 52, and the eccentric wheel 72 abuts against the inner side of the upper conveyor belt 51. By rotating the knob 73, the knob 73 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the eccentric wheel 72 at the bottom to rotate. The eccentric wheel 72 expands against the lower conveyor belt 31, so that the two lower conveyor belts 31 are close to each other, changing the distance between the two lower conveyor belts 31.

[0074] Briefly described, the bevel gear set 64 is composed of two bevel gears, one bevel gear is installed on the driving rod 63, and the other bevel gear is installed on the bottom of the linkage rod 65, and the two bevel gears are meshed with each other.

[0075] Four gears 66 are rotatably installed on the top of the gear support seat, one of which is installed on the top of the linkage rod 65, and two of which are installed on the bottom of the lower conveying wheel 3. The four gears 66 are meshed and connected in sequence, and the four gears 66 are linked, and the two gears 66 installed at the bottom of the lower conveying wheel 3 rotate in opposite directions.

[0076] The reduction box 67 is installed at the bottom of the frame 1, and the motor 68 is installed on one side of the reduction box 67. The reduction box 67 is meshed with the gears of the gear box 6. Power supply components 69 are installed on both sides of the frame 1, and the power supply components 69 provide power for the motor 68.

[0077] The power supply assembly 69 includes two battery mounting boxes and two batteries. The two battery mounting boxes are respectively installed on both sides of the frame 1. The two batteries are respectively installed in the two battery mounting boxes, and the batteries can be removed from the battery mounting boxes. The batteries are electrically connected to the motor 68, and the batteries provide power for the motor 68.

[0080] The conveyor belt is made of flexible material, which can prevent excessive clamping force and fit the vegetables more closely, achieving better flexible clamping, ensuring that the vegetables are clamped to the maximum extent without damaging them, thereby reducing damage to the vegetables. It can greatly improve the harvesting efficiency and can clamp and convey different varieties of vegetables, with a wide range of practical applications, thereby reducing the production costs of planting companies.

[0083] When the utility model is used, any one of the knobs 73 is rotated, and the knob 73 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the eccentric wheel 72 at the bottom to rotate. At the same time, the rotating rod 7 drives the fan gear 71 installed on the top to rotate, and the fan gear 71 drives another fan gear 71 to rotate, so that the other rotating rod 7 drives the eccentric wheel 72 to rotate.
