DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] Reference Figure 1-6 As shown, the fresh corn harvester includes a frame 1, on which a picking platform 11 is installed, on which a cutting device 12, a conveying device 13 and a picking device 14 are installed, and the picking device 14 includes a picking roller group 2, a first conveyor belt group 3 and a second conveyor belt group 4. The first conveyor belt group 3 is arranged below the picking roller group 2 to drive the upper end of the corn plant to move, and the second conveyor belt group 4 is arranged below the picking roller group 2 to drive the lower end of the corn plant to move.

[0024] Through the above scheme, the cutting device 12 cuts off the root of the corn plant, the first conveyor belt group 3 clamps the upper end of the corn plant, and the second conveyor belt group 4 clamps the lower end of the corn plant, thereby driving the corn plant to move through the picking roller group 2. The picking roller group 2 picks the fresh corn on the corn plant and drops it onto the conveying device 13. Since the upper and lower ends of the corn plant are firmly fixed, the picking process is stable, ensuring the quality of the harvested fresh corn.

[0025] As an improved specific embodiment, the first conveyor belt group 3 includes a first belt body 31 and a second belt body 32, and the picking platform 11 includes a picking bracket 15, on which the first bracket 151 and the second bracket 152 are installed, and the first bracket 151 is installed with a first drive motor 33 and a plurality of first pulleys 34, the first drive motor 33 is used to drive the first belt body 31 to rotate, and the second bracket 152 is installed with a second drive motor 35 and a plurality of second pulleys 36, the second drive motor 35 is used to drive the second belt body 32 to rotate, and the plurality of first pulleys 34 abut against the inner side surface of the first belt body 31 toward the second belt body 32, and the plurality of second pulleys 36 all abut against the inner side surface of the second belt body 32 toward the first belt body 31.

[0026] Through the above scheme, the first belt body 31 and the second belt body 32 have a gap for the corn plant to be inserted, and the upper end of the corn plant can be firmly clamped by the flexible clamping of the first belt body 31 and the second belt body 32 and the pressing of the first pulley 34 and the second pulley 36.

[0027] As an improved specific embodiment, the picking bracket 15 is also provided with a first support bar 153 and a second support bar 154, the picking roller group 2 is tilted, and the picking roller group 2 includes a first roller body 21 and a second roller body 22. The first bracket 151 is provided with a first bevel gear group 23 and a second bevel gear group 24. The first bevel gear group 23 is connected to the corresponding first pulley 34, the upper end of the first roller body 21 is connected to the first bevel gear group 23, the lower end of the first roller body 21 is rotatably connected to the first support bar 153, the second bevel gear group 24 is connected to the corresponding second pulley 36, the upper end of the second roller body 22 is connected to the second bevel gear group 24, and the lower end of the second roller body 22 is rotatably connected to the second support bar 154.

[0028] Through the above scheme, the first belt body 31 drives the first pulley 34 to rotate, and then drives the first roller body 21 through the first bevel gear set 23, the second belt body 32 drives the second pulley 36 to rotate, and then drives the second roller body 22 through the second bevel gear set 24, so as to transmit power, and the first roller body 21 and the second roller body 22 rotate in opposite directions, and the flexible transmission can reduce the damage to the fresh corn. During transmission, since the corn plants will squeeze the two sides when passing between the first belt body 31 and the second belt body 32, the first belt body 31 and the second belt body 32 can be close to the first pulley 34 and the second pulley 36. The first belt body 31 and the second belt body 32 are both elastic belts such as belts. By strengthening the tensioning effect of the belt, the friction contact area and the connection effect are increased, ensuring that power can be transmitted, and the flexible connection relationship is strengthened.

[0029] As an improved specific embodiment, the second conveyor belt group 4 includes a third belt body 41 and a fourth belt body 42, a third bracket 155 and a fourth bracket 156 are installed on the picking bracket 15, a third drive motor 43 and a plurality of third pulleys 44 are installed on the third bracket 155, the third drive motor 43 is used to drive the third belt body 41 to rotate, a fourth drive motor 45 and a plurality of fourth pulleys 46 are installed on the fourth bracket 156, the fourth drive motor 45 is used to drive the fourth belt body 42 to rotate, a plurality of third pulleys 44 are abutted on the inner side surface of the third belt body 41 toward the fourth belt body 42, and a plurality of fourth pulleys 46 are all abutted on the inner side surface of the fourth belt body 42 toward the third belt body 41.

[0030] Through the above scheme, there is a gap between the third belt body 41 and the fourth belt body 42 for the corn plant to be inserted, which can flexibly clamp the lower end of the corn plant. The third pulley 44 and the fourth pulley 46 ensure that the belt tension can be firmly clamped to ensure the connection effect, and can synchronously drive the entire corn plant to move synchronously, so as to easily and neatly separate the fresh corn from the corn plant, reduce damage to the fresh corn, and protect the fresh corn as much as possible.

[0031] As an improved specific embodiment, a first inclined rod 5 is installed at the front end of the first bracket 151, and a first guide plate 51 and a first guide wheel 52 are installed on the first inclined rod 5, the first guide wheel 52 is connected to the first belt body 31, and a first guide sprocket 53 is installed on the first guide wheel 52, and a second inclined rod 54 is installed at the front end of the second bracket 152, and a second guide plate 55 and a second guide wheel 56 are installed on the second inclined rod 54, the second guide wheel 56 is connected to the second belt body 32, and a second guide sprocket 57 is installed on the second guide wheel 56.

[0032] Through the above scheme, the upper end of the corn plant is guided to move, thereby ensuring that it is stably clamped and fixed.

[0033] As an improved specific embodiment, the frame 1 is also equipped with a guide plate 16 inclined obliquely to the rear at the rear of the cutting device 12, and a notch 161 is provided on the guide plate 16 for the corn plants to pass through. The notch 161 is arranged in front of the second conveyor belt group 4, and a first guide inclined plate 162 and a second guide inclined plate 163 are respectively provided on the left and right sides of the notch 161.

[0034] Through the above scheme, after clamping the upper end of the corn plant, the guide plate 16 can slightly hinder the lower end of the corn plant, and the lower end of the corn plant is clamped slightly later, so that the corn plant is clamped at an inclined angle, and the corn plant forms an eight-shaped angle with the picking roller group 2, which can better pick the fresh corn. The detached fresh corn is blocked by the corn plant and falls to both sides onto the conveyor belt 131, avoiding falling onto the second conveyor belt group 4, ensuring that the second conveyor belt group 4 can run smoothly.

[0035] As an improved specific embodiment, the front bottom of the picking bracket 15 is also fixedly connected to a connecting bracket 17, and the connecting bracket 17 is arranged in the front and lower part of the notch 161. The cutting device 12 includes a cutting motor 6, which is installed on the connecting bracket 17. The cutting motor 6 is connected to a cutting disc 61, and a plurality of cutting blades 62 are detachably connected to the cutting disc 61.

[0036] Through the above solution, the cutting motor 6 provides independent power, large power cutting, and ensures smooth cutting. The independent cutting blade 62 is easy to replace after damage.

[0037] As an improved specific implementation, the conveying device 13 includes a conveyor belt 131 installed at the bottom of the picking platform 11, and a plurality of elastic partitions 132 arranged at equal intervals are arranged on the conveyor belt 131.

[0038] Through the above solution, the elastic partition 132 divides the conveyor belt 131 into a plurality of compartments, each of which can accommodate fresh corn, thereby separating the fresh corn for easy transportation, and the elastic structure can avoid damaging the fresh corn.

[0039] As an improved specific embodiment, a conveying channel 7 and a collecting box 71 are also installed on the frame 1. The collecting box 71 is provided with an inclined collecting port 72. The lower end of the conveying channel 7 is installed at the rear end of the conveyor belt 131. The conveying channel 7 is inclined backward and upward, and a bent output port 73 is provided at the upper end. The output port 73 is arranged above the lower end of the collecting port 72.

[0040] Through the above scheme, the conveyor belt 131 can deliver the fresh corn to the conveying channel 7, and then transport it to the collecting box 71 through the conveying channel 7, so as to harvest a large amount of fresh corn. The inclined collecting port 72 can easily accommodate the fresh corn.

[0041] As an improved specific implementation, the picking bracket 15 is rotatably connected to the frame 1, and a connecting rod 18 is installed at the bottom. An electric telescopic rod 181 is installed on the frame 1, and one end of the electric telescopic rod 181 is rotatably connected to the connecting rod 18.

[0042] Through the above scheme, the connecting rod 18 is installed on the bottom surface of the picking bracket 15, and the electric telescopic rod 181 can drive the entire picking bracket 15 to rotate, thereby adjusting the height of the cut corn plants and adjusting the harvesting angle to facilitate replacement picking.

[0043] 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.
