In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0042] The front-to-back direction X in the figure is the direction in which the harvester moves when performing harvesting operations.
[0043] like Figures 1 to 5 As shown, the utility model provides a crop divider, including a front body 10, a rear body 20 and a limiting mechanism 30. Among them, the front body 10 is projected in a cone shape in the vertical direction Z, including a tip and a large diameter end; the front end of the rear body 20 is hinged to the large diameter end of the front body 10, and the axis of the hinge is parallel to the left and right direction Y, and the rear end of the rear body 20 is used to connect with the main frame; the limiting mechanism 30 includes a mounting frame 31, a rotating shaft 32 and a support member 33, the mounting frame 31 is fixed to the main frame, the support member 33 is connected to the mounting frame 31 through the rotating shaft 32, the axis of the rotating shaft 32 is parallel to the left and right direction Y, the support member 33 includes a supporting state relatively fixed to the mounting frame 31 and an adjusting state relatively rotating to the mounting frame 31, and the support member 33 can support the front body 10 below.
[0044] Specifically, the tip of the front body 10 is located at the front end of the divider. When the harvester is operating, the front body 10 divides the crops into two left and right strands; the rear body 20 is used to connect the front body 10 and the main frame. The front body 10 and the rear body 20 are hinged, so that the front body 10 can swing around the left and right direction Y relative to the rear body 20, thereby realizing that the front body 10 can swing with the ups and downs of the ground, avoiding damage caused by collision between the front body 10 and the protrusions of the ground. The limiting mechanism 30 is used to limit the lowest point of the swing of the front body 10 relative to the rear body 20. The mounting frame 31 of the limiting mechanism 30 is fixed to the main frame, the support member 33 is rotatably connected to the mounting frame 31 and its rotation axis is parallel to the rotation axis of the front body 10, the support member 33 can rotate or lock relative to the mounting frame 31, and the support member 33 is located at the bottom of the front body 10 to support the front body 10. In this way, before operation, the angle between the support member 33 and the horizontal plane is adjusted according to the working terrain, and then locked. The front body 10 is supported at the bottom by the support member 33, so that the front body 10 can only be flipped upward to avoid the front body 10 flipping downward relative to the rear body 20 and inserting into the pit when there is a pit on the ground.
[0045] Optionally, the limiting mechanism 30 also includes a locking rod 34 and an adjusting nut 35. The mounting frame 31 is provided with a mounting hole 311 for passing the rotating shaft 32 and a waist-shaped hole 312 provided around the axis of the mounting hole 311. The locking rod 34 is relatively fixed to the support member 33 and is slidably arranged in the waist-shaped hole 312. The adjusting nut 35 is threadedly connected to the locking rod 34. The adjusting nut 35 can lock the relative position of the locking rod 34 in the waist-shaped hole 312.
[0046] Specifically, the axial end of the locking rod 34 is provided with a thread for threading with the adjusting nut 35. The axis of the locking rod 34 is parallel to the left-right direction Y and is fixed to the support member 33 along the left-right direction Y. The locking rod 34 passes through the waist-shaped hole 312 and is threadedly connected with the adjusting nut 35. During use, when it is necessary to limit the lowest position of the front body 10, the adjusting nut 35 is loosened to release the abutment relationship with the mounting frame 31, and the support member 33 is rotated around the rotating shaft 32 to adjust the relative position of the support member 33 and the mounting frame 31. After the locking rod 34 reaches the predetermined position, the adjusting nut 35 is screwed so that the adjusting nut 35 abuts against the mounting frame 31 along the axial direction of the locking rod 34. The relative position of the support member 33 and the mounting frame 31 is kept unchanged through the friction between the axial end face of the adjusting nut 35 and the mounting frame 31.
[0047] In other embodiments, the mounting frame can be provided with a plurality of insertion holes around the axial direction of the mounting hole 311, and the locking rod 34 can be selectively inserted into one of them to limit the relative position between the support member 33 and the mounting frame to remain unchanged. Optionally, the limiting mechanism 30 further includes a gasket 36, which is sleeved on the locking rod 34 and clamped between the adjusting nut 35 and the mounting frame 31.
[0048] Specifically, the gasket 36 can increase the friction between the adjusting nut 35 and the mounting frame 31, so that the relative fixed relationship between the supporting member 33 and the mounting frame 31 is more stable when the supporting member 33 is in its supporting state.
[0049] The friction of the gasket 36 can be increased by using a material with a larger friction coefficient or by increasing the contact area, which is a prior art and will not be described in detail here.
[0050] Optionally, one end of the support member 33 away from the mounting frame 31 is rotatably connected to a roller 37, and the axis of rotation is parallel to the left-right direction Y, and the support member 33 contacts the precursor 10 through the roller 37. In this way, the support member 33 contacts the precursor 10 through the roller 37, which can reduce the direct contact friction between the support member 33 and the precursor 10.
[0051] Optionally, the rear body 20 is hinged to the main frame, and the axis of the hinge is parallel to the left-right direction Y. The limiting mechanism 30 also includes a positioning pin 38, which can be inserted into the rear body 20 and the mounting frame 31 at the same time to lock the relative position of the rear body 20 and the main frame. Generally, the harvester is equipped with an ear picking device, which is installed below the grain divider. When the ear picking device needs to be inspected or replaced, the ear picking device can be exposed by flipping the rear body 20. In normal use, the rear body 20 and the mounting frame 31 are fixed by the positioning pin 38.
[0052] Since the harvester inevitably vibrates during operation, the positioning pin 38 may be disengaged from the mounting frame 31 and / or the rear body 20, which in turn causes the rear body 20 to frequently swing relative to the mounting frame 31 and fail to operate normally. Thus, a tie ring 39 is rotatably connected to one axial end of the positioning pin 38, and the axis of rotation is perpendicular to the axial direction of the positioning pin 38. The tie ring 39 can be sleeved on the rear body 20 or the mounting frame 31 to maintain the insertion state of the positioning pin 38 with the rear body 20 and the mounting frame 31.
[0053] Specifically, one of the mounting frame 31 and the rear body 20 is provided with a protrusion, and the other is provided with an avoidance hole. After the protrusion passes through the avoidance hole along the vertical direction Z, the positioning pin 38 penetrates the protrusion along the horizontal direction. The positioning pin 38 can abut against the axial end face of the avoidance hole to prevent the protrusion from withdrawing from the avoidance hole. The clamping ring 39 is sleeved on the protrusion, so that the sleeve direction of the clamping ring 39 and the protrusion is the vertical direction Z, which is perpendicular to the horizontal plug-in direction of the positioning pin 38 and the protrusion, and can prevent the positioning pin 38 from withdrawing from the protrusion.
[0054] Optionally, the crop divider further includes a baffle 41 , which is mounted on both sides of the front body 10 in the left-right direction Y, and the baffle 41 allows crops to pass through in one direction from front to back.
[0055] Specifically, the crop divider includes a front body 10 and a rear body 20 arranged in sequence along the left-right direction Y, the rear body 20 is located on the rear side of the front body 10, the rear body 20 corresponds to the front body 10 one by one, and a feed channel is formed between two adjacent front bodies 10, and a baffle 41 is installed on both sides of the front body 10 in the left-right direction Y to control the entry and exit of crops into and out of the feed channel. Under the action of the harvester, the crops can cause the baffle 41 to swing relative to the front body 10, so that the crops enter the feed channel from front to back. In the process of picking crop fruits, the harvester applies force to the fruits away from the crop stems, so that the fruits move from back to front, and the baffle 41 can stop the fruits to prevent them from falling from the front end of the crop divider.
[0056] In this embodiment, the baffle 41 is made of a flexible material and can be elastically deformed. In other embodiments, the baffle 41 is hinged to the front body 10, and a torsion spring is provided at the hinge, which makes the baffle 41 always in an intercepting state. The front body 10 is also provided with a limit block. When the fruit hits the baffle 41 from the back to the front, the limit block supports the baffle 41 and prevents it from opening.
[0057] During the operation, the crops mainly rub against the front body 10 and / or the rear body 20 on both sides of the left-right direction Y. Therefore, protective plates are installed on both sides of the front body 10 and / or the rear body 20 in the left-right direction Y. By adding the protective plates, the protective plates contact the crops instead of directly rubbing against the crops by the front body 10 and / or the rear body 20, thereby reducing the use loss of the front body 10 and / or the rear body 20.
[0058] Generally, in order to reduce the weight of the crop divider, the front body 10 and the rear body 20 are generally made of engineering plastics, and the protective plate is made of metal plates.
[0059] In this embodiment, the protective plate includes a first protective plate 51 and a second protective plate 52. The front body 10 is provided with the first protective plate 51 on both sides of the left-right direction Y, and the first protective plate 51 is embedded in the surface of the front body 10; the rear body 20 is provided with the second protective plate 52 on both sides of the left-right direction Y, and the second protective plate 52 is embedded in the surface of the rear body 20. Specifically, the front body 10 and the rear body 20 are both provided with protective plates, and the front body 10 and the rear body 20 are provided with mounting grooves on both sides of the left-right direction Y, and the protective plates are placed in the mounting grooves, and the surfaces of the protective plates are flush with the open end surfaces of the mounting grooves. The protective plates are fixed to the mounting grooves by bolting or gluing, so that the raised protective plates can be prevented from interfering with crops.
[0060] A corn harvester is also provided, comprising a crop divider and a main frame, wherein the crop divider is detachably connected to the main frame. In this way, the corn harvester can adjust the crop divider according to the growth height and lodging condition of the harvested crops and the flatness of the soil slope in the harvesting area, so that the crops can be collected by the crop divider and the front body 10 is prevented from being inserted into the ground during the movement of the harvester. The crop divider can be adapted to a variety of main frames.
[0061] In addition, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
