Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a self-propelled corn combine harvester with whole-plant recovery. Background Technology

[0002] The ear-picking device at the front of the machine removes the corn ears from the plant. The harvested ears are then transported to an ear collection bin via a conveyor system. The conveyor system, typically composed of chains, scrapers, or conveyor belts, reliably transports the ears to the designated location. After harvesting the ears, the machine processes the corn stalks. Whole-plant harvesters can cut, crush, or bale the stalks for subsequent transportation and utilization, such as for silage or biomass energy.

[0003] In existing technologies, some corn combine harvesters cause some straw powder to remain on the screen surface when crushing straw powder, resulting in excessive accumulation of straw powder on the screen, which leads to blockage of the straw powder feeding and inability to feed in a timely manner. To address this issue, a whole-plant recycling type self-propelled corn combine harvester is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a whole-plant recycling type self-propelled corn combine harvester, which aims to improve the problem in the prior art where powder remains on the screen surface, causing excessive accumulation of straw powder on the screen, resulting in blockage of straw powder feeding and inability to feed in a timely manner.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A whole-plant recycling type self-propelled corn combine harvester includes a straw powder recycling bin. A turning assembly for turning the straw powder is fixedly connected to the inner wall of the straw powder recycling bin. A rotating motor is fixedly connected to the inner wall of the straw powder recycling bin. A rotating column is fixedly connected to the drive end of the rotating motor. A control rod is fixedly connected to the outer wall of the rotating column. A connecting rod is fixedly connected to the outer wall of the control rod. A vibrating screen is fixedly connected to the other end of the connecting rod. Two connecting rods are fixedly connected to both sides of the bottom of the vibrating screen. A fixing rod is fixedly connected to the inner wall of the connecting rod.

[0007] As a further description of the above technical solution:

[0008] The material turning assembly includes a fixing plate, which is fixedly connected to the inner wall of the straw powder recycling bin. A control motor is fixedly connected to the inner wall of the fixing plate. A rotating rod is fixedly connected to the drive end of the control motor. A connecting plate is fixedly connected to the outer wall of the rotating rod. Rotating gears are fixedly connected to both ends of the connecting plate.

[0009] As a further description of the above technical solution:

[0010] Both of the fixed rods are rotatably connected to the inner wall of the straw powder recycling bin, and a crushing bin is fixedly connected to the top of the straw powder recycling bin. The other end of the connecting rod is rotatably connected to the inner wall of the straw powder recycling bin.

[0011] As a further description of the above technical solution:

[0012] A tilting rod is fixedly connected to the outer wall of the rotating gear, and a rotating disk is fixedly connected to the outer wall of the tilting rod.

[0013] As a further description of the above technical solution:

[0014] The rotating disk is slidably connected to the inner wall of the straw powder recycling bin, and the outer wall of the rotating gear is meshed with the inner wall of the fixed plate.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the straw powder recycling bin is equipped with a corn straw powder extractor, and the discharge end of the corn straw powder extractor is fixedly connected to a discharge port, which is fixedly connected to the inner wall of the straw powder recycling bin.

[0017] As a further description of the above technical solution:

[0018] A corn recycling machine is fixedly connected to the side wall of the crushing chamber, and a corn collection chamber is fixedly connected to the side wall of the straw powder recycling chamber. The corn collection chamber is located directly below the corn recycling machine, and a track is provided directly below the straw powder recycling chamber and the corn collection chamber.

[0019] As a further description of the above technical solution:

[0020] A conveyor belt is fixedly connected to the outer wall of the crushing chamber, and a straw cutter is fixedly connected to the other end of the conveyor belt. A straw picker is fixedly connected to the inner wall of the straw cutter.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the rotating motor starts and drives the rotating column to rotate. The rotation of the rotating column drives the control rod to rotate. The rotation of the control rod drives the connecting rod to rotate up and down around the rotating column. The movement of the connecting rod drives the vibrating screen to vibrate. The gaps in the vibrating screen screen out the completely crushed straw fragments, while the fragments that are not completely crushed continue to be crushed inside the crushing chamber. On the one hand, this can prevent the discharge of the incompletely crushed straw, and on the other hand, it can prevent the completely crushed fragments from staying too long inside the crusher and affecting the crusher. Moreover, the vibrating structure can promptly screen out the completely crushed powder, avoiding the impact of excessive powder retention on the subsequent powder output.

[0023] 2. The control motor drives the rotating rod to rotate, which in turn drives the connecting rod to rotate. The rotation of the connecting rod drives the rotating gear to rotate circumferentially inside the fixed plate, causing the turning rod to stir inside the straw powder recycling bin. This stirs up the straw fragments and prevents them from becoming too wet after crushing and sticking inside the straw powder recycling bin, which could cause blockage at the discharge port or stick to the inner wall of the straw powder recycling bin during the discharge process, thus affecting the discharge.

[0033] Reference Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a whole-stalk recycling type self-propelled corn combine harvester, including a straw powder recycling bin 1 for crushing corn straw. The inner wall of the straw powder recycling bin 1 is fixedly connected to a turning component for turning and stirring the straw powder. A rotating motor 2 is fixedly connected to the inner wall of the straw powder recycling bin 1 for controlling the rotation of a rotating column 3. The drive end of the rotating motor 2 is fixedly connected to the rotating column 3 for driving a control rod 4 to rotate. The outer wall of the rotating column 3 is fixedly connected to the control rod 4. The rotation of the control rod 4 drives the connecting rod 5 to rotate. The rotation of the connecting rod 5 drives the vibrating screen 14 to vibrate and screen the crushed straw so that it falls into the straw powder recycling bin 1.

[0034] A connecting rod 5 is fixedly connected to the outer wall of the control rod 4 to drive the vibrating screen 14 to vibrate and screen. The other end of the connecting rod 5 is fixedly connected to the vibrating screen 14. Two connecting rods 16 are fixedly connected to both sides of the bottom of the vibrating screen 14 to fix the vibrating screen 14. A fixing rod 15 is fixedly connected to the inner wall of the connecting rod 16 to facilitate the rotation of the vibrating screen 14 on the inner wall of the straw powder recycling bin 1. Both fixing rods 15 are rotatably connected to the inner wall of the straw powder recycling bin 1. A crushing bin 13 is fixedly connected to the top of the straw powder recycling bin 1 for crushing straw. The other end of the connecting rod 5 is rotatably connected to the inner wall of the straw powder recycling bin 1. A corn straw powder extractor is provided on the inner wall of the straw powder recycling bin 1 to extract the completely crushed straw powder.

[0035] The discharge end of the corn stalk powder extractor is fixedly connected to a discharge port 18 for extracting the crushed stalk powder. The discharge port 18 is fixedly connected to the inner wall of the stalk powder recycling bin 1. The side wall of the crushing bin 13 is fixedly connected to a corn recycling machine 17 for collecting corn separated from the stalk. The side wall of the stalk powder recycling bin 1 is fixedly connected to a corn collection bin 21 for storing the collected whole corn plants. The corn collection bin 21 is located directly below the corn recycling machine 17. The stalk powder recycling bin 1 and the corn collection bin 21 are directly below a track 22 for controlling the movement of the corn combine harvester. The outer wall of the crushing bin 13 is fixedly connected to a conveyor belt 23 for conveying corn stalks and collected corn. The other end of the conveyor belt 23 is fixedly connected to a stalk cutter 20 for cutting corn stalks. The inner wall of the stalk cutter 20 is fixedly connected to a corn ear picker 19 for removing corn ears.

[0036] Reference Figure 1 , Figure 2 and Figure 6 The turning assembly includes a fixed plate 8 for limiting the rotation of the rotating gear 12. The fixed plate 8 is fixedly connected to the inner wall of the straw powder recycling bin 1. A control motor 9 is fixedly connected to the inner wall of the fixed plate 8 for controlling the rotation of the rotating rod 10. The drive end of the control motor 9 is fixedly connected to the rotating rod 10. A connecting plate 11 is fixedly connected to the outer wall of the rotating rod 10 for driving the rotating gear 12 to rotate. Both ends of the connecting plate 11 are fixedly connected to the rotating gear 12. The rotation of the rotating gear 12 drives the turning rod 7 to rotate and turn the straw powder inside the straw powder recycling bin 1. The outer wall of the rotating gear 12 is fixedly connected to the turning rod 7. The outer wall of the turning rod 7 is fixedly connected to the turning plate 7 for blocking the internal turning assembly and preventing straw powder from entering the turning assembly. The turning plate 6 is slidably connected to the inner wall of the straw powder recycling bin 1. The outer wall of the rotating gear 12 and the inner wall of the fixed plate 8 are meshed with each other.

[0037] Working principle: The corn combine harvester cuts the corn stalks through the front straw cutter 20, cuts the corn stalks, and then picks the corn through the front ear picker 19. The corn stalks are then transported to the corn recycling machine 17 and the straw crusher through the conveyor belt 23. At this time, the components inside the crushing chamber 13 crush the corn stalks that have been transported there, and the crushed corn stalk powder falls into the straw powder recycling chamber 1.

[0038] At this time, the rotating motor 2 starts and drives the rotating column 3 to rotate. The rotation of the rotating column 3 drives the control rod 4 to rotate. The rotation of the control rod 4 drives the connecting rod 5 to rotate up and down around the rotating column 3. The movement of the connecting rod 5 drives the vibrating net 14 to vibrate. The gaps in the vibrating net 14 screen out the completely crushed straw fragments, while the fragments that are not completely crushed continue to be crushed inside the crushing chamber 13.

[0039] The presence of internal moisture in the completely cut straw fragments can cause them to stick together, potentially affecting the discharge process. Therefore, a turning component is added to stir the straw fragments inside to prevent them from sticking together. The motor 9 drives the rotating rod 10 to rotate, which in turn drives the connecting rod 16 to rotate. The rotation of the connecting rod 16 causes the rotating gear 12 to rotate circumferentially inside the fixed plate 8, which in turn drives the turning rod 7 to stir inside the straw powder recycling bin 1, thereby turning over the straw fragments and preventing them from sticking together inside the straw powder recycling bin 1 and affecting subsequent discharge.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
