Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular, to a fruit ear box. Furthermore, this utility model also relates to a harvester including the aforementioned fruit ear box. Background Technology
[0002] With the continuous advancement of fresh corn harvester technology, farmers, while pursuing efficient harvesting, are placing more stringent demands on the integrity of the ears and the rate of harvest breakage. Given that ordinary ear-harvesting boxes are often simply designed and only 2.5-3 meters high, the ears are easily damaged during the process of being thrown into the box. Against this backdrop, developing a highly adaptable ear-harvesting box that can reduce the breakage rate is particularly important. This box must not only have a sufficiently large volume to reduce damage caused by ears falling from a height, but also ensure efficient and rapid unloading during the unloading process.
[0003] Currently, sweet corn harvesters operate by having the header system pick the ears and drop them, then a multi-stage conveyor system tosss the ears into the ear box. Once the ear box is full, the harvester stops to unload the grain. The ear boxes currently available come in two types: one is a one-piece thin-shell structure welded together. This type of ear box is prone to deformation during welding and has a small volume, requiring frequent stops for unloading during harvesting, thus affecting work efficiency; the other type is a large ear box with a buffer lifting mechanism, suitable for large harvesters. This type often has a larger structure, causing the ears to fall too high when thrown into the ear box, making them prone to damage, and unloading is relatively slow. Utility Model Content
[0004] This utility model provides a grain box and a harvester to solve the technical problems of excessive grain drop height during the harvesting process and low unloading efficiency in the prior art.
[0005] According to one aspect of the present invention, a fruit ear box is provided, comprising:
[0006] The box has an open top to hold the fruit bunches, and its width gradually decreases from top to bottom;
[0007] A base plate assembly is disposed at the bottom of the box body, including a first base plate that matches the shape and size of the bottom of the box body and a second base plate connected to one side of the first base plate. The sum of the widths of the second base plate and the first base plate is greater than or equal to the width at a preset height position of the box body.
[0008] A buffer lifting mechanism is disposed between the first base plate and the bottom of the box body. The buffer lifting mechanism includes an elastic support member and / or a hydraulic support mechanism, which is used to support the first base plate at the preset height in a no-load state, and to generate buffer after the first base plate is loaded and gradually descend as the load increases.
[0009] A rotating structure is disposed between the second base plate and the first base plate, used to support the second base plate at a preset angle to the first base plate when the first base plate is at a preset height, and used to allow the second base plate to rotate relative to the first base plate based on the rotating structure during the descent of the first base plate.
[0010] As a further improvement to the above technical solution, a sliding mechanism that cooperates with the side wall of the box is provided on the side edge of the second base plate near the side wall of the box.
[0011] As a further improvement to the above technical solution, the side wall of the housing is provided with a slide rail for cooperating with the sliding mechanism.
[0012] As a further improvement to the above technical solution, the sliding mechanism includes a slider hinged to the side edge of the second base plate. The side edge of the second base plate is provided with a mounting protrusion corresponding to the position of the slide rail. The slider is mounted on the mounting protrusion via a rotating shaft, and the slider cooperates with the slide rail.
[0013] As a further improvement to the above technical solution, at least two sliders are provided on the side edge of the second base plate, and the number of slide rails matches the number of sliders.
[0014] As a further improvement to the above technical solution, the ear box also includes a rotating mechanism, which is located in the middle or upper part of one side of the box body and is connected to the harvester.
[0015] As a further improvement to the above technical solution, a step structure is provided on the side of the box body away from the rotating mechanism, which connects to the bottom of the box body.
[0016] As a further improvement to the above technical solution, the rotating structure includes hinges respectively connected to the first base plate and the second base plate, and the plurality of hinges are evenly spaced.
[0017] As a further improvement to the above technical solution, the cross-section of the box body is an inverted right trapezoid, and the second base plate is connected to the right angle side of the first base plate away from the right trapezoid; or, the cross-section of the box body is an inverted isosceles trapezoid, and the second base plate is connected to both sides of the first base plate.
[0018] According to another aspect of the present invention, a harvester is also provided, which includes the aforementioned ear-shaped box.
[0019] This utility model has the following beneficial effects:
[0020] The ear-shaped grain box incorporates a base plate assembly and a buffer lifting mechanism. These components ensure that the first and second base plates are at a preset height when unloaded, reducing the falling height of the ears and consequently decreasing the impact force upon entry. This lowers the probability of damage from collisions. As ears are added, the load on the base plate assembly increases, causing the first base plate to descend, thus maintaining the box's effective volume and space. The second base plate and rotating structure ensure that when the first base plate is at the preset height, the second base plate forms a preset angle with it, matching the overall width of the box. During the descent of the first base plate, the second base plate, interfering with the side wall of the box, rotates inwards via the rotating structure, its rotation direction pointing upwards towards the base plate assembly. This ensures the base plate assembly matches the width of the box, guaranteeing it supports the ears and preventing them from falling through gaps below the first base plate. Furthermore, when the box is tilted to unload, the elastic support springs back up as the weight decreases, further accelerating the unloading process.
[0021] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0031] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0034] like Figures 1 to 6 As shown, the ear-of-fruit box in this embodiment includes:
[0035] The box is 900mm wide, with an open top to hold the fruit bunches, and its width gradually decreases from top to bottom.
[0036] The base plate assembly 100 is disposed at the bottom of the box 900, including a first base plate 101 that matches the shape and size of the bottom of the box 900 and a second base plate 102 connected to one side of the first base plate 101. The sum of the widths of the second base plate 102 and the first base plate 101 is greater than or equal to the width at a preset height position of the box 900.
[0037] A buffer lifting mechanism 300 is disposed between the bottom of the first base plate 101 and the box 900. The buffer lifting mechanism 300 includes an elastic support member 301 and / or a hydraulic support mechanism, which is used to support the first base plate 101 at a preset height in a no-load state, and to generate buffer after the first base plate 101 is loaded and gradually descend as the load increases.
[0038] The rotating structure 103 is disposed between the second base plate 102 and the first base plate 101. It is used to support the second base plate 102 at a preset angle to the first base plate 101 when the first base plate 101 is at a preset height, and to make the second base plate 102 rotate relative to the first base plate 101 based on the rotating structure 103 during the descent of the first base plate 101.
[0039] The box 900 is designed with an open top and a width that gradually decreases from top to bottom to accommodate the ears of fruit and unload the fruit. The buffer lifting mechanism 300 can be one or more of an elastic support 301 or a hydraulic support mechanism. The elastic support 301 is implemented using a compression spring of the prior art, and the hydraulic support mechanism can be implemented using a hydraulic cylinder of the prior art. At the preset height, it is preferable that the second bottom plate 102 is parallel to the first bottom plate 101, and the sum of the widths of the second bottom plate 102 and the first bottom plate 101 matches the width of the box 900 at that position.
[0040] In some embodiments, the rotating structure 103 includes hinges connected to the first base plate 101 and the second base plate 102 respectively. Multiple hinges are evenly spaced and the second base plate 102 is rotated relative to the first base plate 101 by means of the hinges, and the rotation angle is limited; that is, the first base plate 101 and the second base plate 102 are parallel at a preset height.
[0041] Understandably, the fruit ear box 900 is equipped with a base plate assembly 100 and a buffer lifting mechanism 300, which ensure that the first base plate 101 and the second base plate 102 are at a preset height when unloaded. This reduces the falling height of the fruit ears, thereby reducing the impact force when the fruit ears fall into the fruit ear box and lowering the probability of damage caused by collision. As the fruit ears are added, the load on the base plate assembly 100 increases, and the first base plate 101 descends, ensuring the effective volume and space of the fruit ear box. By setting the second base plate 102 and the rotating structure 103, when the first base plate 101 is at the preset height... The second base plate 102 is at a preset angle to the box, and its overall width matches the width of the box 900. During the descent of the first base plate 101, the second base plate 102 interferes with the side wall 200 of the box 900 and rotates inward based on the rotating structure 103. The rotation direction tends to be upward of the base plate assembly 100, so that the base plate assembly 100 can keep matching the width of the box 900, ensuring that the base plate assembly 100 receives the ears of grain and prevents the ears of grain from falling into the first base plate 101 through the gap. On the other hand, when the ear of grain box is overturned to unload the grain, the elastic support 301 bounces up again as the weight is reduced, further accelerating the unloading process.
[0042] It should be noted that the enclosure 900 also includes a side panel assembly, a front wall assembly 400, and a rear wall assembly 500 located on the side wall 200, which are connected by bolts and other structures. Its split structure ensures that the volume is large enough, while each component is manufactured separately during the production process, making it less prone to deformation.
[0043] It should be understood that the cross-section of the box 900 in this embodiment is approximately an inverted isosceles trapezoid, and the two sides of the first base plate 101 are respectively connected to the second base plate 102, that is, the two base plates rotate simultaneously during the lifting process to maintain width matching; in other embodiments, the cross-section of the box 900 may also be approximately an inverted right trapezoid, and the right angle side of the first base plate 101 away from the right angle trapezoid is connected to the second base plate 102.
[0044] In some embodiments, a sliding mechanism 600 is provided on the side edge of the second base plate 102 near the side wall 200 of the box body 900, which cooperates with the side wall 200 of the box body 900. This allows the second base plate 102 to maintain relative sliding with the side wall 200 of the box body 900 as the first base plate 101 descends and rotates, preventing excessive gaps between the base plate assembly 100 and the side wall 200 of the box body 900 from causing the fruit ears to fall inside. The side wall 200 of the box body 900 is provided with a slide rail 201 for cooperating with the sliding mechanism 600, and the sliding mechanism 600 can be embedded in the slide rail 201 to ensure a tight fit between the second base plate 102 and the side wall 200 of the box body 900, reducing the risk of fruit ears falling inside. The clearance is as follows: Specifically, the sliding mechanism 600 includes a slider 603 hinged to the side edge of the second base plate 102. The side edge of the second base plate 102 is provided with a mounting protrusion 601 corresponding to the position of the slide rail 201. The slider 603 is mounted on the mounting protrusion 601 through a rotating shaft 602. The slider 603 cooperates with the slide rail 201. The end of the mounting protrusion 601 and the slider 603 are respectively provided with shaft holes through which the rotating shaft 602 passes. The slider 603 cooperates with the slide rail 201 to keep parallel to the slide rail 201 and move along the slide rail 201. During the movement of the second base plate 102, the two sides rotate relative to the first base plate 101 and the slider 603 respectively. The structure is simple, the fit is tight, and the assembly is convenient.
[0045] It is understandable that at least two sliders 603 are provided on the side edge of the second base plate 102, and the number of slide rails 201 matches the number of sliders 603, so that the rotation and movement of the second base plate 102 are more stable, ensuring the load-bearing effect of the base plate assembly 100 and ensuring the stability of the overall structure.
[0046] It should be understood that the ear box also includes a rotating mechanism 700, which is located in the middle or upper part of one side of the box body 900. The rotating mechanism 700 is connected to the harvester, and the ear box is tilted to unload based on the rotating mechanism 700. Furthermore, a stepped structure 800 is provided on the side of the box body 900 away from the rotating mechanism 700, which connects to the bottom of the box body 900, so that the overall center of gravity of the box body 900 tends to the side of the rotating mechanism 700, thereby reducing the lever arm and reducing the output force required for unloading.
[0047] On the other hand, a preferred embodiment of the present invention also provides a harvester that uses the above-mentioned ear-shaped box.
