Description

Technical Field

[0001] This utility model relates to the field of straw baling technology, and in particular to a combined corn harvesting and straw baling machine. Background Technology

[0002] Corn is an important food crop. After harvesting, corn produces a lot of corn stalks. Since corn stalks contain rich nutrients and usable chemical components, they need to be recycled. In the process of recycling corn stalks, balers are needed to gather the corn stalks together, which facilitates subsequent stacking and transportation.

[0003] For example, Chinese patent CN221104149U, concerning a corn stalk harvesting and baling device, relates to the field of stalk baling technology. It includes a baler with a discharge bin at its end. Columns are symmetrically distributed on both sides of the discharge bin, and each column has an internal electric sliding platform. During use, the device effectively prevents baled stalks from falling directly to the ground from the discharge bin opening through the cooperation of a guide plate and a push plate, thus preventing the stalks from scattering or becoming loose during their descent.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: when the device piles straw on the ground, it is not only necessary to stop the device first and run it in place to put down the straw pile, but also to reset the push plate after putting it down so that the device can continue to move. Otherwise, the push plate will hit the straw pile and prevent the device from continuing to move forward. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the device needs to stop moving when the straw pile is lowered, which affects the baling efficiency. To this end, we propose a corn harvesting and straw baling combined operation machine.

[0006] To achieve the above objectives, this application adopts the following technical solution: a corn harvesting and straw baling combined operation machine, including a baler, a discharge bin fixedly connected to the discharge end of the baler, a discharge port opened at the bottom of the tail of the discharge bin, a discharge platform movably connected inside the discharge port, connecting blocks fixedly connected to both sides of the outer wall of the discharge bin near the tail, a first telescopic cylinder provided on each of the two connecting blocks, a fixed block fixedly connected to the telescopic ends of the two first telescopic cylinders, connecting shafts fixedly connected to both sides of the outer wall of the discharge platform, the two connecting shafts respectively bearing connected to the two fixed blocks, support legs fixedly connected to both sides of the outer wall of the discharge bin near the tail, guide grooves opened on the side of each support leg near the discharge bin, guide sliding shafts fixedly connected to both sides of the outer wall of the discharge platform, the two guide sliding shafts respectively slidably connected in adjacent guide grooves, used to rotate when the discharge platform moves downward to lower the straw pile from the tail of the device.

[0007] Preferably, the feeding platform has a hollow structure with openings at the top and bottom. Both sides of the inner cavity of the feeding platform are fixedly connected to a support shaft. The support shaft is located on the side of the inner cavity of the feeding platform away from the baler. There are several support shafts arranged horizontally and symmetrically. Each support shaft is movably sleeved with a feeding roller.

[0008] Preferably, support blocks are fixedly connected to both sides of the inner cavity of the feeding platform and near the bottom. The top surfaces of the two support blocks are fixedly connected to the second telescopic cylinders. The telescopic ends of the two second telescopic cylinders are fixedly connected to the push plate. The push plate is located on the side of the inner cavity of the feeding platform near the baler and is used to lift one end of the straw pile so that the straw pile can be lowered and stand upright on the ground in coordination with the feeding platform.

[0009] Preferably, movable openings are provided on both sides of the outer wall of the discharge hopper near the tail end, the movable openings are connected to the discharge port, and the fixed block and the guide slide shaft are movably connected in the movable openings.

[0010] Preferably, baffles are fixedly connected to both sides of the top surface of the feeding platform to prevent the straw pile from rolling off the sides of the device during feeding.

[0011] Preferably, both of the support legs are fixedly connected to the bottom surface with casters, so that the support legs can be moved easily when supported on the ground.

[0012] Preferably, the guide groove is composed of a vertical section and an arc-shaped section, with the vertical section located on the upper side and the arc-shaped section located on the lower side, and the upper end of the arc-shaped section and the lower end of the vertical section being connected.

[0013] The technical effects and advantages of this utility model are as follows: In this invention, the feeding platform can be rotated to an inclined state after it descends, so that the straw pile falls from the side away from the baler. Therefore, when the device continues to move forward, it will not be blocked by the straw pile on the ground. There is no need to stop the device when the feeding platform and other mechanisms are reset. When the feeding platform and other mechanisms are reset, the device can continue to move to pick up and bale the straw, thereby effectively improving the working efficiency of the device.

[0014] In this invention, the side of the straw pile closest to the baler can be lifted upwards by raising the push plate, causing the straw pile to tilt on the unloading platform. With the tilt of the unloading platform, the straw pile stands upright on the ground after landing, and the horizontal surface of the straw pile contacts the ground. This greatly reduces the extent to which the straw pile continues to move forward due to inertia after landing, and avoids the situation where it scatters or becomes loose due to excessive inertial movement after landing. The device can place the straw pile while maintaining movement, further improving the baling efficiency of the device. Attached Figure Description

[0017] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] Reference Figure 1-7 As shown, this utility model provides a technical solution: a corn harvesting and straw baling combined operation machine, including a baler 1, a discharge bin 2 fixedly connected to the discharge end of the baler 1, a discharge port 3 opened at the bottom of the tail of the discharge bin 2, a discharge platform 4 movably connected inside the discharge port 3, connecting blocks 5 fixedly connected to both sides of the outer wall of the discharge bin 2 near the tail, each connecting block 5 is equipped with a first telescopic cylinder 6, and a fixing block 7 fixedly connected to the telescopic ends of the two first telescopic cylinders 6, and the discharge platform 4... Both sides of the outer wall are fixedly connected to connecting shafts 8, and the two connecting shafts 8 are respectively bearing connected to two fixed blocks 7. Both sides of the outer wall of the discharge bin 2 and near the tail are fixedly connected to support legs 9. The two support legs 9 are provided with guide grooves 10 on the side near the discharge bin 2. Both sides of the outer wall of the unloading platform 4 are fixedly connected to guide sliding shafts 11, and the two guide sliding shafts 11 are respectively slidably connected in adjacent guide grooves 10, which are used to rotate the unloading platform 4 when it moves downward to lower the straw pile from the tail of the device.

[0019] To make it easier for the straw pile to slide off the inclined feeding platform 4, the feeding platform 4 has a hollow structure with openings at the top and bottom. Support shafts 12 are fixedly connected to both sides of the inner cavity of the feeding platform 4. The support shafts 12 are located on the side of the inner cavity of the feeding platform 4 away from the baler 1. There are several support shafts 12 arranged horizontally and symmetrically. Each support shaft 12 is movably sleeved with a feeding roller 13. When the feeding platform 4 is tilted, the rotating feeding roller 13 can greatly reduce the frictional resistance between the straw pile and the feeding platform 4, so that the straw pile can slide off the feeding platform 4 more easily.

[0020] In order to lift the end of the straw pile closest to the baler 1 from the feeding platform 4, support blocks 14 are fixedly connected to both sides of the inner cavity of the feeding platform 4 near the bottom. The top surfaces of the two support blocks 14 are fixedly connected to the second telescopic cylinders 15. The telescopic ends of the two second telescopic cylinders 15 are fixedly connected to the push plate 16. The push plate 16 is located on the side of the inner cavity of the feeding platform 4 closest to the baler 1. It is used to lift one end of the straw pile, so that the straw pile can stand upright on the ground after falling down with the feeding platform 4. When the push plate 16 rises, it will lift the end of the straw pile closest to the baler 1 from the feeding platform 4, so that the straw pile is tilted on the top surface of the feeding platform 4. With the tilt of the feeding platform 4 itself, the straw pile has a large tilt angle with the ground, so that it can stand upright on the ground after landing.

[0021] To prevent the discharge bin 2 from affecting the fixed block 7 and the guide slide shaft 11, movable openings 17 are provided on both sides of the outer wall of the discharge bin 2 near the tail. The movable openings 17 are connected to the discharge port 3. The fixed block 7 and the guide slide shaft 11 are movably connected in the movable openings 17. The movable openings 17 provide a certain space for the fixed block 7 and the guide slide shaft 11, so that the discharge platform 4 can smoothly enter the discharge port 3 without being prevented from entering due to the fixed block 7 and the guide slide shaft 11 hitting the bottom of the discharge bin 2.

[0022] To prevent the straw pile from rolling off the sides of the feeding platform 4, baffles 18 are fixedly connected to both sides of the top surface of the feeding platform 4. These baffles are used to prevent the straw pile from rolling off the sides of the device during feeding. After the feeding platform 4 descends and moves out of the feeding port 3, the two baffles 18 block the straw pile from both sides to prevent it from rolling off the sides of the feeding platform 4 onto the ground.

[0023] To reduce the frictional resistance between the support leg 9 and the ground, the bottom surfaces of both support legs 9 are fixedly connected with movable wheels 19, which facilitates the movement of the support leg 9 when it is supported on the ground. The movable wheels 19 are supported on the ground to reduce the frictional resistance between the support leg 9 and the ground.

[0024] In order to drive the unloading platform 4 to rotate when the guide slide shaft 11 slides down to near the ground, the guide groove 10 is composed of a vertical section 101 and an arc section 102. The vertical section 101 is located on the upper side and the arc section 102 is located on the lower side. The upper end of the arc section 102 is connected to the lower end of the vertical section 101. When the guide slide shaft 11 slides down into the arc section 102, the arc section 102 will drive the guide slide shaft 11 to slide in an arc, so that the unloading platform 4 rotates around the connecting shaft 8.

[0025] Working principle: First, the baler 1 is connected to the tractor. The tractor pulls the baler, and the tractor's picking mechanism picks up the straw into the baler 1. The baling components inside the baler 1 bale the straw into a pile and transport the straw pile to the discharge bin 2. The straw pile moves to the unloading platform 4 located at the rear of the discharge bin 2. Then, the first telescopic cylinder 6 is activated, which pushes the unloading platform 4 down. The unloading platform 4 drives the guide shaft 11 down. During descent, the material platform 4 first moves vertically downward within the vertical section 101 of the guide groove 10. When the material platform 4 approaches the ground, the guide shaft 11 enters the arc-shaped section 102 of the guide groove 10. The guide shaft 11 moves along the trajectory of the arc-shaped section 102, causing the material platform 4 to rotate around the connecting shaft 8. This rotates the side of the material platform 4 away from the baler 1 to tilt downwards, causing the straw pile to tilt and automatically slide from the top surface of the material platform 4 onto the ground. One side of the baler 1 falls down, so the device will not be blocked by the straw pile on the ground when it continues to move forward. There is no need to stop the device when the feeding platform 4 and other mechanisms reset. When the feeding platform 4 and other mechanisms reset, the device can keep moving to pick up and bale the straw, thereby effectively improving the working efficiency of the device. While the feeding platform 4 rotates, the second telescopic cylinder 15 pushes the push plate 16 to rise. The rise of the push plate 16 lifts the side of the straw pile close to the baler 1 upward, so that the straw pile tilts on the feeding platform 4. Through the tilt of the feeding platform 4 and the push of the push plate 16, the straw pile can be tilted significantly after landing, so that the straw pile stands upright on the ground. The horizontal surface of the straw pile is in contact with the ground, which greatly reduces the extent of the straw pile continuing to move forward due to inertia after landing, and avoids the situation of scattering or loosening due to excessive inertial movement after landing. The device can place the straw pile while keeping moving, further improving the baling efficiency of the device.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
