[0001] This application relates to the field of agricultural equipment technology, and in particular to a material storage device and a harvester. Background Technology

[0002] To meet the demand for high-yield crops, most crops are currently harvested using mechanical equipment, which usually refers to harvesters. During the harvesting process, when the storage bins are full, the materials in the harvester's storage device need to be transferred to large transport vehicles.

[0003] In traditional material storage device designs, augers or tilting structures are usually used for unloading. However, the former has a complex structure and low unloading efficiency, while the latter cannot be adapted to large transport vehicles with high vehicle height due to center of gravity issues, which is not conducive to improving production efficiency. Utility Model Content

[0004] In view of this, this application aims to provide a material storage device to improve the adaptability of the material storage device to transport vehicles of different heights, so as to improve production efficiency.

[0006] Furthermore, the storage unit includes a mounting frame, a storage box hinged at one end to the mounting frame, and a second drive unit hinged between the storage box and the mounting frame; the storage cavity is disposed on the storage box, the mounting frame is hinged to the frame, the first drive unit is hinged between the mounting frame and the frame, and the power output end of the second drive unit is extendable and retractable, driving the storage box to flip relative to the mounting frame for unloading.

[0007] Furthermore, the storage box is hinged to the front end of the mounting frame, and the rear end of the mounting frame is hinged to the machine frame.

[0008] Furthermore, the top of the storage box is provided with a discharge port that communicates with the storage cavity; The front wall of the storage box slopes downwards towards the rear of the storage box.

[0009] Furthermore, the mounting bracket includes a base, a first mounting post disposed at the front end of the base, and a second mounting post disposed at the rear end of the base, both the first and second mounting posts extending upwards from the base; the storage box is hinged to the top of the first mounting post, and the second drive unit is hinged between the bottom end of the second mounting post and the front of the storage box.

[0010] Furthermore, the distance between the first mounting post and the second mounting post gradually increases along the direction away from the base.

[0011] Furthermore, the base is provided with a first buffer for contacting the storage box; and / or, a reinforcing post is provided between the second mounting post and the base.

[0012] Furthermore, at least a portion of the sidewall of the storage box is formed with perforations, and a wire mesh is used to cover the perforations; and / or, the first drive unit uses a first hydraulic cylinder, and the second drive unit uses a second hydraulic cylinder.

[0013] Furthermore, the frame includes a main body and a mounting beam disposed on the main body, and the mounting beam extends upward toward the main body; a second buffer is provided at the top of the main body, the second buffer being used to abut against the storage part, the storage part being hinged to the mounting beam.

[0014] Compared with related technologies, this application has the following advantages: (1) The storage device described in this application is provided with a storage part that is hinged to the frame at one end, and a first drive part that is hinged between the storage part and the frame. The first drive part can drive the storage part to rotate relative to the frame to adjust the height of the storage part. Its structure is simple and easy to implement, and it can adapt to transport vehicles of different heights, which is conducive to improving production efficiency.

[0015] (2) The storage unit includes a mounting frame hinged to the frame, a storage box hinged to the mounting frame and having a storage cavity, and a second drive unit hinged between the storage box and the mounting frame. The first drive unit is hinged between the mounting frame and the frame. The second drive unit can drive the storage box to flip relative to the mounting frame to unload the material, so that the storage box can be flipped independently to achieve rapid unloading, which is conducive to improving work efficiency. At the same time, it can also cooperate with the first drive unit to achieve unloading of the storage box at different heights, which is conducive to improving the versatility of the storage device.

[0016] (3) The storage box is hinged to the front end of the mounting frame and the rear end of the mounting frame is hinged to the frame. This allows the material to slide down naturally when the storage box is flipped, reducing residue and improving unloading efficiency. The hinged design at the rear end also makes it easy to adjust the height of the storage box. This improves the versatility of the storage device and the unloading efficiency, which is conducive to further improving production efficiency.

[0017] (4) The top of the storage box is provided with a discharge port that communicates with the storage cavity. The front side wall of the storage box is inclined from top to bottom towards the rear side of the storage box, which can guide the flow of materials and facilitate the discharge of materials from the discharge port at the top of the storage box, which is conducive to improving the discharge efficiency and thus conducive to improving production efficiency.

[0018] (5) The mounting frame includes a base, a first mounting post at the front end of the base, and a second mounting post at the rear end of the base. Both the first and second mounting posts extend upwards from the base. The storage box is hinged to the top of the first mounting post, and the second drive unit is hinged between the bottom end of the second mounting post and the front of the storage box. This allows the frame structure of the mounting frame to evenly distribute the weight of the storage box, improve the load-bearing capacity, enhance the overall stability, and also allows the drive unit to be closer to the center of gravity of the storage box, reducing the driving force requirement and making the power transmission more efficient.

[0019] (6) Along the direction away from the base, the distance between the first mounting post and the second mounting post gradually increases, which facilitates the installation of the storage box and avoids interference with the front side wall of the storage box. It also enables reliable support for the storage box.

[0020] (7) By setting a first buffer on the base for contacting the storage box, the impact force when the storage box contacts the base can be effectively buffered, mechanical wear and vibration can be reduced, and the service life of the storage box can be extended. A reinforcing column is provided between the second mounting column and the base, which can improve the connection strength, disperse local stress, enhance the torsional rigidity and load-bearing capacity of the storage device, and make it more stable and reliable when bearing the weight of the storage box and the dynamic force of the flipping operation, which is conducive to improving the reliability of the storage device.

[0021] (8) At least part of the side wall of the storage box is formed with perforated holes and wire mesh is used to cover the perforated holes. This can reduce the structural weight of the storage box and is conducive to the overall lightweight design. The first drive unit adopts the first oil cylinder and the second drive unit adopts the second oil cylinder. This can take advantage of their large thrust and high stability to facilitate height adjustment and unloading under high load conditions, and also ensure the reliability of the storage device.

[0022] (9) The frame includes a main body and a mounting beam on the main body. The mounting beam extends upward to the main body, which can provide stable installation support for the storage part and optimize the movement range of the storage part, thereby further improving the versatility of the storage device. A second buffer is provided at the top of the main body. The second buffer is used to abut against the storage part. The storage part is hinged to the mounting beam, which can effectively reduce the impact force when the storage part contacts the top of the frame, reduce mechanical wear and vibration, and extend the service life of the storage device.

[0023] Another object of this application is to provide a harvester equipped with a material storage device as described in any one of the above.

[0024] The harvester described in this application, by setting up the material storage device as described above, can improve the harvester's adaptability to different transport vehicles, thereby improving the harvester's working efficiency. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0030] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] An embodiment of the first aspect of this application provides a material storage device, which is typically used on harvesters. Furthermore, the material storage device of this embodiment, through innovative structural design, is capable of adapting to transport vehicles of different heights, which is beneficial to improving production efficiency.

[0033] In related technologies, in order to meet the demand for high-yield crops, most crops are currently harvested using mechanical equipment. The aforementioned mechanical equipment usually refers to harvesters. During the harvesting process, when the storage bin is full, the material in the harvester's storage device needs to be transferred to a large transport vehicle.

[0034] In traditional material storage device designs, augers or tilting structures are usually used for unloading. However, the former has a complex structure and low unloading efficiency, while the latter cannot be adapted to large transport vehicles with high vehicle height due to the center of gravity problem. The unloading process often requires the cooperation of a loader. The material needs to be unloaded into the loader first, and then the loader is used to transfer it onto the large transport vehicle, which greatly increases the operating cost and is not conducive to improving production efficiency.

[0035] In view of this, in order to overcome the shortcomings of related technologies, the storage device in this embodiment combines... Figures 1 to 3 In terms of overall design, it includes a frame 100, a storage section 200 hinged to the frame 100 at one end, and a first drive section 101 hinged between the storage section 200 and the frame 100.

[0036] The storage section 200 has a storage cavity 2021. The power output end of the first drive section 101 can extend and retract, and drive the storage section 200 to rotate relative to the frame 100 to adjust the height of the storage section 200.

[0037] Therefore, by providing a storage section 200 with one end hinged to the frame 100, and a first drive section 101 hinged between the storage section 200 and the frame 100, and the first drive section 101 being able to drive the storage section 200 to rotate relative to the frame 100 to adjust the height of the storage section 200, the structure is simple and easy to implement, and can adapt to transport vehicles of different heights, thereby improving production efficiency.

[0038] Based on the above overview, specifically, for the storage device in this embodiment, any unmentioned structures can be referenced from existing storage devices. Furthermore, it is worth mentioning that the support described in this embodiment can be made of square steel, which is well-known to those skilled in the art. Of course, it can also be made of materials such as channel steel or profiles, as long as the structural strength of the support can be guaranteed; further details will not be provided here.

[0039] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the storage unit 200 includes a mounting frame 201, a storage box 202 hinged at one end to the mounting frame 201, and a second drive unit 203 hinged between the storage box 202 and the mounting frame 201. A storage cavity 2021 is provided on the storage box 202. The mounting frame 201 is hinged to the frame 100. A first drive unit 101 is hinged between the mounting frame 201 and the frame 100. The power output end of the second drive unit 203 is extendable and retractable, driving the storage box 202 to flip relative to the mounting frame 201 for unloading.

[0040] This configuration allows the storage box 202 to be flipped independently for quick unloading, which improves work efficiency. At the same time, it can also work with the first drive unit 101 to unload the storage box 202 at different heights, which improves the versatility of the storage device.

[0041] In specific implementation, the storage unit 200 further includes a material guiding device 204 located at the discharge end of the storage bin. The material guiding device 204 includes a material guiding trough 2041, hinged plates 2042 on both outer walls of the material guiding trough 2041, one end of which is fixedly connected to the material guiding trough 2041, and the other end is hinged to the mounting frame 201, and a third drive unit 2043 hinged between the material guiding trough 2041 and the mounting frame 201. The power output end of the third drive unit 2043 is extendable and retractable, driving the material guiding trough 2041 to rotate relative to the mounting frame 201, thus enabling the material guiding device 204 to unfold and retract. This guides the material in the storage bin 202 into the transport vehicle, reducing waste and avoiding excessive space occupation.

[0042] Specifically, the aforementioned third drive unit 2043 can be a hydraulic cylinder, which can utilize its advantages of high thrust and high stability to facilitate the deployment and retraction of the material guide device 204. Of course, it can also be a drive structure well known to those skilled in the art, such as a pneumatic cylinder, or it can be manually deployed and supported by a strut, as long as it can satisfy the requirements of deploying and retracting the material guide device 204 and providing reliable support, which will not be elaborated further here.

[0043] Combination Figure 1 and Figure 3 As shown, in some exemplary embodiments, the storage box 202 is hinged to the front end of the mounting bracket 201, and the rear end of the mounting bracket 201 is hinged to the frame 100.

[0044] This design allows materials to slide off naturally when the storage box 202 is flipped, reducing residue and improving unloading efficiency. The hinged design at the rear also makes it easy to adjust the height of the storage box 202, thereby improving the versatility of the storage device and increasing unloading efficiency, which is conducive to further improving production efficiency.

[0045] Combination Figure 2 As shown, in some exemplary embodiments, the top of the storage box 202 is provided with a discharge port 2022 communicating with the storage cavity 2021, and the front sidewall of the storage box 202 slopes from top to bottom towards the rear side of the storage box 202. The advantage of this arrangement is that it guides the flow of materials, facilitating the discharge of materials from the discharge port 2022 at the top of the storage box, thereby improving unloading efficiency and ultimately contributing to increased production efficiency.

[0046] Combination Figure 2 and Figure 3 As shown, in some exemplary embodiments, the mounting bracket 201 includes a base 2011, a first mounting post 2012 located at the front end of the base 2011, and a second mounting post 2013 located at the rear end of the base 2011. Both the first mounting post 2012 and the second mounting post 2013 extend upwards from the base 2011. A storage box 202 is hinged to the top end of the first mounting post 2012, and a second drive unit 203 is hinged between the bottom end of the second mounting post 2013 and the front of the storage box 202.

[0047] This design allows the frame structure of the mounting bracket 201 to evenly distribute the weight of the storage box 202, improving load-bearing capacity and overall stability. It also allows the drive unit to be closer to the center of gravity of the storage box 202, reducing the driving force requirement and making power transmission more efficient.

[0048] In specific implementation, the second drive unit 203 of this embodiment can be hinged not only between the bottom end of the second mounting post 2013 and the front of the storage box 202, but also between the base 2011 and the front of the storage box 202, thereby reducing the inclination of the second drive unit 203 and improving safety. It should be noted that the hinge position between the second drive unit 203 and the mounting bracket 201 in this embodiment can be adaptively adjusted according to the length of the storage box 202, which will not be elaborated further here.

[0049] Continue to combine Figures 1 to 3 As shown, in some exemplary embodiments, the distance between the first mounting post 2012 and the second mounting post 2013 gradually increases along the direction away from the base 2011. This facilitates the installation of the storage box 202 and avoids interference with the front wall of the storage box 202. It also provides reliable support for the storage box 202.

[0050] Combination Figure 3 As shown, in some exemplary embodiments, the base 2011 is provided with a first buffer 20111 for contacting the storage box 202. The advantage of this arrangement is that it can effectively buffer the impact force when the storage box 202 contacts the base 2011, reduce mechanical wear and vibration, and extend the service life of the storage box 202.

[0051] In specific implementation, the first buffer 20111 in this embodiment can be made of rubber, a material well-known to those skilled in the art, which has advantages such as low cost, easy molding, and wear resistance. Of course, it can also be other buffer structures, such as spring buffer structures or hydraulic buffer structures, as long as they can buffer the impact force when the storage box 202 contacts the base 2011, and reduce mechanical wear and vibration. Further details will not be provided here.

[0052] A reinforcing column 2014 is provided between the second mounting column 2013 and the base 2011, which can improve the connection strength, disperse local stress, and enhance the torsional rigidity and load-bearing capacity of the storage device, making it more stable and reliable when bearing the weight of the storage box 202 and the dynamic force of the flipping operation, which is conducive to improving the reliability of the storage device.

[0053] It is worth mentioning that the reinforcing column 2014 in this embodiment can be made of square steel, which is well known to those skilled in the art. Of course, it can also be made of materials such as channel steel or profiles, as long as the structural strength of the support can be guaranteed, which will not be elaborated here.

[0054] Combination Figure 1 As shown, in some exemplary embodiments, at least a portion of the sidewalls of the storage box 202 are formed with perforations, and a wire mesh 2023 is used to cover the perforations. This reduces the structural weight of the storage box 202 and is beneficial for the overall lightweight design.

[0055] The first drive unit 101 uses a first hydraulic cylinder, and the second drive unit 203 uses a second hydraulic cylinder. By utilizing their advantages of high thrust and high stability, it is easy to achieve height adjustment and tilting unloading under high load conditions, and also ensure the reliability of the storage device.

[0056] In specific implementation, the storage box 202 in this embodiment can be covered not only by the wire mesh 2023 mentioned above, but also by thin steel plates or other materials known to those skilled in the art, as long as it can cover the gap and reduce the structural weight of the storage box 202.

[0057] The first drive unit 101 and the second drive unit 203 in this embodiment can not only adopt the above-mentioned hydraulic cylinder, but also drive structures well known to those skilled in the art, such as lead screw motors or cylinders, as long as they can meet the requirements of large thrust and high stability, which will not be elaborated further.

[0058] Combination Figure 2 and Figure 3 As shown, in some exemplary embodiments, the frame 100 includes a main body 102 and a mounting beam 103 disposed on the main body 102, with the mounting beam 103 extending upward toward the main body 102. This arrangement provides stable mounting support for the storage section 200 while also optimizing the range of motion of the storage section 200, thereby further enhancing the versatility of the storage device.

[0059] In specific implementation, the frame 100 of this embodiment includes longitudinal beams 1021 arranged along the four corners of a rectangle, and crossbeams 1022 connecting adjacent longitudinal beams 1021. This results in a simple and reliable structure, and the storage device can be adapted to different harvesters by adjusting the height of the longitudinal beams 1021. Of course, the frame 100 of this embodiment can also be the harvester itself, and the mounting beams 103 can be directly mounted on the harvester.

[0060] The top of the main body 102 is provided with a second buffer 104, which is used to abut against the storage part 200. The storage part 200 is hinged to the mounting beam 103. The advantage of this arrangement is that it can effectively reduce the impact force when the storage part 200 contacts the top of the frame 100, reduce mechanical wear and vibration, and extend the service life of the storage device.

[0061] In specific implementation, the second buffer 104 in this embodiment can be made of rubber, a material well-known to those skilled in the art, which has advantages such as low cost, easy molding, and wear resistance. Of course, it can also be other buffer structures, such as spring buffer structures or hydraulic buffer structures, as long as they can buffer the impact force when the storage box 202 contacts the base 2011 and reduce mechanical wear and vibration, which will not be elaborated further here.

[0063] The storage section 200 has a storage cavity 2021.

The mounting frame 201 includes a base 2011, a first mounting post 2012 located at the front end of the base 2011, and a second mounting post 2013 located at the rear end of the base 2011.
