[0021] Reference Figure 1-4 As shown, the novel fresh corn harvester includes a frame 1, on which a picking device 11, a conveying device 12 and a collecting device 13 are installed, the conveying device 12 includes a conveyor belt 121, the collecting device 13 includes a collecting pipe 2 and a collecting box 131, the lower end of the collecting pipe 2 is provided with an inlet 21, the inlet 21 is arranged at the rear end of the conveyor belt 121, the upper end of the collecting pipe 2 is provided with an outlet 22, the outlet 22 is arranged above the collecting box 131, the collecting pipe 2 is provided with a collecting belt 3, a differential belt 4 arranged above the collecting belt 3 and a debris removal channel 5 arranged on one side of the collecting belt 3, and the other side of the collecting belt 3 is provided with a debris blowing fan 6 for blowing away debris.

[0022] Through the above scheme, the fresh corn is picked by the picking device 11 and sent to the entrance 21 through the conveyor belt 121 of the conveying device 12. The conveyor belt 121 drives the fresh corn to rise and send it to the output port 22 into the collecting box 131. In the process of rising and conveying, the differential belt 4 arranged above the collecting belt 3 clamps the fresh corn to prevent the fresh corn from being blown off, and can use a large air volume to remove impurities. The fresh corn is driven to roll through different conveying speeds to avoid clamping impurities, so that the impurity blowing fan 6 can blow the impurities into the impurity discharge channel 5 as much as possible and discharge them. The fresh corn with impurities removed is sent to the collecting box 131, so that the impurities of the harvested fresh corn are removed as much as possible, and the quality of the harvested fresh corn is guaranteed.

[0023] As an improved specific embodiment, the collecting belt 3 includes a first belt body 31, and a first driving roller 32 and a first driven roller 33 are respectively installed at the upper and lower ends of the first belt body 31. A first driving motor 34 is also installed on the collecting pipe 2, and the first driving motor 34 is connected to the first driving roller 32. A plurality of equidistant partitions 311 are installed on the first belt body 31.

[0024] Through the above scheme, multiple partitions 311 divide the first belt body 31 into multiple areas of equal size. Fresh corn can be accommodated in these areas and separated by the partitions 311. At the same time, the fresh corn cups are moved by the partitions 311 and are not easy to roll down, so they are conveniently transported obliquely to the rear to the collection box 131.

[0025] As an improved specific embodiment, the differential belt 4 includes a second belt body 41, and a second driving roller 42 and a second driven roller 43 are respectively installed at the upper and lower ends of the second belt body 41. A second driving motor 44 is also installed on the collection pipe 2, and the second driving motor 44 is connected to the second driving roller 42. A plurality of equidistantly arranged rubber plates 411 are installed on the second belt body 41.

[0026] Through the above scheme, the rubber sheet 411 can abut against the fresh corn, and as the second belt body 41 moves, the fresh corn is driven to roll in the area separated by the first belt body 31, so that the debris attached to the fresh corn can be rolled off and blown away, ensuring that the debris can be removed as much as possible.

[0027] As an improved specific implementation method, the left and right sides of the output port 22 are fixedly connected with an adjustment seat 76, the first driven roller 33 is fixedly connected with a driving gear 74, the driving gear 74 is meshingly connected with a passive gear 73, the passive gear 73 is rotatably connected with a gear seat 731, the gear seat 731 is fixedly connected to the inner wall of the output port 22, the passive gear 73 is rotatably connected with a driving rod 72, one end of the driving rod 72 is rotatably connected with a connecting rod 71, the connecting rod 71 is rotatably connected with an adjustment plate 7, the left and right ends of the adjustment plate 7 are fixedly connected with adjustment rods 75, and the two adjustment rods 75 are rotatably connected to the corresponding adjustment seats 76.

[0028] Through the above scheme, as the first driving roller 32 rotates, the driving gear 74 drives the passive gear 73 to rotate, and the driving rod 72 rotates, driving the adjustment plate 7 to swing up and down through the connecting rod 71, so that the fresh corn transported from the collecting belt 3 to the output port 22 is randomly thrown into the collecting box 131. The fresh corn can be evenly distributed in the collecting box 131 as it rolls, avoiding unilateral accumulation of the fresh corn.

[0029] As an improved specific implementation, the rear end of the conveyor belt 121 is arranged in the entrance 21 and above the first driving roller 32, and a gap is provided between the conveyor belt 121 and the collecting belt 3 for the partition plate 311 to pass through.

[0030] Through the above scheme, the setting of the gap ensures smooth operation and facilitates the falling of debris.

[0031] As an improved specific implementation method, a spacing adjustment mechanism 8 is also installed on both sides of the collecting pipe 2, and the spacing adjustment mechanism 8 includes a first slide rail 81, a second slide rail 82, a first lifting cylinder 83 and a second lifting cylinder 84. The first slide rail 81 and the second slide rail 82 are vertically arranged, the first slide rail 81 is slidably connected to the first slider 85, the lifting end of the first lifting cylinder 83 is connected to the first slider 85, the second slide rail 82 is slidably connected to the second slider 86, the lifting end of the second lifting cylinder 84 is connected to the second slider 86, the second drive motor 44 and the second drive roller 42 are respectively installed on the corresponding first slider 85, and the two ends of the second driven roller 43 are respectively installed on the corresponding second slider 86.

[0032] Through the above solution, the second driving roller 42 and the second driven roller 43 can be raised and lowered to adjust their positions, so as to adapt to fresh corns of different sizes and ensure smooth collection.

[0033] As an improved specific implementation method, a wind groove 61 connected to the impurity blowing fan 6 is also arranged in the collecting pipe 2 along the length direction, and the wind groove 61 is provided with a long air outlet 62, and the air outlet 62 is provided with a plurality of downwardly inclined air guide plates 63 to form a downwardly inclined air duct to blow the debris into the impurity exhaust channel 5.

[0034] Through the above solution, the fresh corn on the collecting belt 3 in the entire collecting pipe 2 can be blown evenly for a long time by relying on multiple air guide plates 63.

[0035] As an improved specific implementation, the impurity discharge channel 5 is provided with a blocking net 51 for blocking corn, and a guide fan 52 is installed at the lower end of the impurity discharge channel 5.

[0036] Through the above solution, the blocking net 51 can ensure that the corn does not fall into the debris discharge channel 5, ensuring that the fresh corn can be transported smoothly.

[0037] As a specific embodiment of the improvement, a control console 14 is also installed on the frame 1, and a baffle plate 15 is installed at the rear of the picking device 11. The baffle plate 15 is arranged above the conveyor belt 121, and the rear end is connected to the collecting pipe 2 to form a placement trough 151 for placing the picked corn plants. The placement trough 151 is provided with an inclined mouth 152 on the outer side, and a driving blower 16 is installed on the other side of the placement trough 151.

[0038] Through the above scheme, the harvested corn plants will be clamped and transported to the placement groove 151 on the shielding plate 15, so as to prevent debris from being mixed with the harvested fresh corn.

[0039] As an improved specific implementation, the collecting pipe 2 is a flat pipe and is tilted toward the upper rear. The collecting pipe 2 is provided with an inclined plane 23 toward the picking device 11 .

[0040] Through the above solution, the inclined plane 23 facilitates the placement of the harvested corn plants and prevents them from falling over.

[0041] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
