Description

Technical Field

[0001] This utility model relates to the technical field of corn conveying devices, and more specifically, to an anti-tangling conveying device for corn harvesters. Background Technology

[0002] A corn harvester is an agricultural implement that mechanically performs multiple tasks in one pass when corn is mature, including ear picking, stacking, and returning the stalks to the field. The process is as follows: The corn harvester picks the ears while the corn is still growing (called standing ear picking). The ear picking rollers and plates break the ear stalks. Due to the height difference between the inner and outer picking rollers, the ears fall into the ear box. Once the box is full, the ears are opened and piled up. A high-speed rotating cutter cuts the stalks at the root, and the stalks are then shredded into 3-5 cm pieces by a crushing mechanism. After chopping, the stalks fall to the ground naturally. The ears are then transported to the field, where they are hulled by a peeler, dried, and threshed.

[0003] Based on the above, the inventors have discovered that during corn harvesting, corn stalks and leaves can become entangled in the conveying device. Over time, this can lead to debris getting tangled during transport, reducing the efficiency of corn harvesting and causing equipment damage. Therefore, in view of this, the inventors have researched and improved the existing structure to provide an anti-entanglement conveying device for corn harvesters, aiming to achieve a more practical purpose.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figures 1-5A corn harvester anti-tangling conveying device includes a device body 1, with two support feet 2 fixedly welded to the bottom of the device body 1. A conveyor belt 3 is installed inside the device body 1, and a fixing plate 4 is fixedly connected to one side of the inside of the device body 1. Several push plates 5 are provided on the surface of the conveyor belt 3. A feed box 6 is fixedly connected to one side of the top of the device body 1, and an mounting plate 7 is fixedly connected to the inside of the feed box 6. A fixing frame 8 is fixedly connected to the bottom of the device body 1, and two connecting plates 9 are fixedly connected to one side of the fixing frame 8. A movable frame 12 is slidably connected inside the two connecting plates 9, and a drive mechanism is fixedly welded to one side of the movable frame 12. The output end of the motor 10 is connected to the cleaning roller 11 via a coupling. A hydraulic cylinder 13 is fixedly connected to the bottom side of the fixed frame 8. The bottom of the feed box 6 has a discharge port 14. Rubber strips 15 are fixedly connected to the top of several push plates 5 respectively. The top side of the fixed plate 4 is inclined, and the top of the mounting plate 7 is also inclined. The fixed plate 4 is fixedly connected to the inside of the device body 1. The top of the fixed plate 4 is inclined. When one end of the device body 1 is placed at the discharge end of the harvester, the corn falls to the inclined part of the top of the fixed plate 4 and slides to the top of the conveyor belt 3, thus achieving the operation of conveying corn.

[0029] See Figure 2 The cleaning roller 11 is rotatably connected to the inside of the two connecting plates 9. The bottom of the fixed plate 4 and the top of the rubber strip 15 are spaced apart. The surface of the cleaning roller 11 is evenly covered with brushes. The top of the two connecting plates 9 is fixedly connected to the bottom of the device body 1. When corn is conveyed on the top of the conveyor belt 3, stalks and corn leaves will get mixed in and wrap around the conveyor belt, causing damage to the device and reducing the conveying efficiency. The cleaning roller 11 cleans the two adjacent push plates 5 inside the conveyor belt 3 to prevent debris from wrapping around the surface of the conveyor belt 3.

[0030] See Figure 3 , Figure 4 The cleaning roller 11 has protrusions on both sides. The top of the telescopic shaft of the hydraulic cylinder 13 is fixedly connected to the bottom center of the movable frame 12. The movable frame 12 is slidably connected to the inside of the two connecting plates 9. When the hydraulic cylinder 13 is started, the movable frame 12 can be moved up and down periodically, which facilitates the cleaning of the surface of the conveyor belt 3 and avoids the cleaning roller 11 from directly colliding with the push plate 5. It is highly practical.

[0031] See Figure 5Several push plates 5 are set perpendicular to the ground, and the bottom of the push plates 5 is fixedly connected to the surface of the conveyor belt 3 by rubber pads; several rubber strips 15 are respectively set with semi-circular cross sections, and one side of the mounting plate 7 is set with a gap between it and the top of the rubber strip 15. The rubber strip 15 is set on the top of the push plate 5. When the corn slides into the top of the conveyor belt 3 along the top of the fixing plate 4, the top of the push plate 5 is prevented from directly contacting the corn, causing damage to the corn and increasing the corn harvest.

[0032] In use: Place one end of the device at the discharge end of the harvester. The top of the fixed plate 4 is inclined, so that the corn falls to the inclined part of the top of the fixed plate 4 and slides down to the top of the conveyor belt 3, thus achieving the operation of conveying corn. When the corn is conveyed on the top of the conveyor belt 3, stalks and corn leaves will get mixed in and wrap around the conveyor belt device, causing damage to the device and reducing the conveying efficiency. The cleaning roller 11 cleans the two adjacent push plates 5 inside the conveyor belt 3 to prevent debris from wrapping around the surface of the conveyor belt 3. The movable frame 12 is slidably connected to the inside of the two connecting plates 9. Activating the hydraulic cylinder 13 can make the movable frame 12 move up and down periodically, which facilitates the cleaning of the surface of the conveyor belt 3 and at the same time prevents the cleaning roller 11 from directly colliding with the push plate 5. It is highly practical. A rubber strip 15 is set on the top of the push plate 5. When the corn slides down the top of the fixed plate 4 into the top of the conveyor belt 3, the top of the push plate 5 is prevented from directly contacting the corn and causing damage to the corn, thus increasing the corn harvest.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
