[0034] See also Figures 1 to 8 As shown, the utility model provides a material storage bin 100, including a fixed bracket 10, the fixed bracket 10 is used to support the material storage bin 100; a sliding bracket 20, the sliding bracket 20 is used to slide when the material storage bin 100 is lifted; an oil cylinder 40, the oil cylinder is used to provide power when the material storage bin is lifted; a lifting limit device 30, when the material storage bin 100 rises to a preset height, the lifting limit device 30 is used to limit the sliding bracket 20 from continuing to rise, thereby limiting the rise of the material storage bin 100;

[0035] The lifting limit device 30 includes a first limit plate 31, which is installed on the fixed bracket 10 according to the preset height of the storage bin 100; a limit hook 32, which includes a limit groove 321, and the limit hook 32 is engaged with the first limit plate 31 through the limit groove 321, thereby limiting the lifting position of the storage bin 100; a fixed seat 33, which is installed on the sliding bracket 20, and the limit hook 32 is connected to the fixed seat 33, and the limit hook 32 moves within the limit of the fixed seat 33.

[0036] In the process of dumping the harvested materials from the storage bin 100 to the transfer vehicle, the storage bin 100 needs to be raised to a preset position, which is determined according to the height of the transfer vehicle. The storage bin 100 includes a fixed bracket 10, a sliding bracket 20, and an oil cylinder 40. The sliding bracket 20 raises the storage bin to a preset position along the direction of the fixed bracket 10, and limits the rise of the storage bin 100 through the lifting limit device 30. The first limit plate 31 of the lifting limit device 30 is fixed on the fixed bracket 10, and the limit hook 32 is engaged with the first limit plate 31, so that the rising action of the storage bin 100 is stopped. The fixed seat 33 installed on the sliding bracket 20 is connected to the limit hook 32. Accordingly, the limit hook 32 moves with the rise of the sliding bracket 20. When it rises to the preset position of the storage bin, it is engaged with the first limit plate 31, thereby limiting the sliding bracket 20 from driving the storage bin 100 to continue to rise.

[0037] By installing the lifting limit device 30 on the fixed bracket 10 and the sliding bracket 20, on the one hand, the storage bin 100 can be limited from continuing to rise, and on the other hand, the inertial falling of the storage bin 100 due to its own load can be prevented, thereby increasing the safety and reliability of the crop transfer process.

[0038] Preferably, the lifting limit device 30 includes a spring 34, and the two ends of the spring 34 are respectively connected to the fixed seat 33 and the limit hook 32, and are used to control the contact between the first limit plate 31 and the limit hook 32. The spring 34 connecting the fixed seat 33 and the limit hook 32 has a tension, that is, the spring 34 can control the rebound of the limit hook 32. Due to the existence of the spring 34, the fixed seat 33 and the limit hook 32 always maintain a relatively stable shape.

[0039] Preferably, the fixed bracket 10 includes a fixed beam 11, a rising groove 12 is arranged on one side of the fixed beam 11, and the sliding bracket 20 rises to a preset height along the direction of the rising groove 12; the lifting limit device 30 includes a second limit plate 36, the second limit plate 36 is connected to the fixed beam 11, and the first limit plate 31 is installed on one side of the rising groove 12 and is connected to the fixed beam 11 through the second limit plate 36.

[0040] During the process of the sliding bracket 20 rising along the rising groove 12, the second limit plate 36 limits the moving position of the sliding bracket 20. The installation height of the second limit plate 36 is the preset height of the storage bin. The second limit plate 36 installed here clamps the sliding bracket 20, affecting the execution of the rising action of the storage bin. The first limit plate 31 is connected to the fixed beam 11 through the second limit plate 36, forming a surrounding structure for the fixed beam 11, further preventing the sliding bracket from rising. It should be noted that at the preset height position, the second limit plate 36 is equivalent to the fixed gasket installed on the first limit plate 31. The second limit plate 36 combined with the first limit plate 31 can more effectively limit the rising process of the sliding bracket 20.

[0041] Preferably, the first limit plate 31 includes a bayonet 311. When the sliding bracket 20 drives the storage bin 100 to rise to a preset height, the bayonet 311 abuts against the limit slot 321 to limit the displacement of the sliding bracket 20. When the storage bin 100 rises, the first limit plate 31 is not connected to the limit hook 32. As the storage bin 100 rises, the limit hook 32 rises with the storage bin 100 driven by the sliding bracket 20. When the storage bin 100 rises to a preset height, the bayonet 311 is connected to the limit slot 321. As the sliding bracket 20 further moves, the bayonet 311 is embedded in the limit slot 321. At this time, the limit slot position 321 is connected to the bayonet 311 at a right angle. When the storage bin 100 rises to a preset height and flips over, the bayonet 311 is vertically embedded in the limit slot 321, and the bayonet 311 fits with the limit slot 321.

[0042] Preferably, the limiting groove 321 is provided with two opposite rounded openings 322. When the bayonet 311 and the limiting groove 322 are fitted together, the limiting groove 321 on the limiting hook 32 is provided with two opposite rounded openings 322 to stabilize the structure of the limiting hook 32, so as to reduce the stress when the bayonet 311 and the limiting groove 321 are fitted together.

[0043] Preferably, a roller 35 is provided at one end of the limit hook 32. When the storage bin 100 rises, the roller 35 fits the storage bin 100 to reduce sliding friction. In a static state, the storage bin 100 generates pressure on the limit hook 32, thereby affecting the shape structure of the limit hook 32 and further affecting the limiting effect. Therefore, the roller 35 is provided at one end of the limit hook 32. On the one hand, during the rising process of the storage bin 100, the pressure acting on the limit hook 32 can be reduced, making the structure of the lifting limit device more stable. On the other hand, due to the existence of the roller 35, the friction between the storage bin 100 and the limit hook 32 is smaller, and the sliding bracket 20 drives the storage bin 100 to rise more efficiently.

[0044] Preferably, the fixing seat 33 includes a fixing groove 331, and one end of the limit hook 32 is fixed to the fixing groove 331 by a pin. Through this fixing method, the limit hook 32 is controlled to rotate and act within the range of the fixing groove 331, and the use structure stability of the lifting limit device 30 is stronger.

[0045] Preferably, the limit hook 32 and the fixing seat 33 are provided with a spring mounting hole, and the spring 34 is connected to the mounting hole. Due to the existence of the elastic force of the spring 34, there is an elastic connection between the limit hook 32 and the fixing seat 33 in addition to the pin connection of the fixing groove 331, and the relative position of the limit hook 32 and the fixing seat 33 is controlled by the spring 34 to maintain the connection stability between the limit hook 32 and the first limit plate 31. Specifically, when the storage bin 100 rises to the preset position and flips over, the pressure of the storage bin 100 on the limit hook 32 disappears, and the force that maintains the fitting state of the bayonet 311 and the limit groove 321 disappears. At this time, in order to stabilize the limiting function of the lifting limit device 30, the spring 35 connected between the fixing seat 33 and the limit hook 32 generates an elastic force to limit the bayonet 311 and the limit groove 321 from falling off, thereby ensuring the stable implementation of the lifting limit device 30. By providing mounting holes on the limit hook 32 and the fixing seat 33 to connect the spring 33 , the mounting structure is more solid and the reliability of the overall lifting limit device 30 is higher.

[0046] By installing the lifting limit device 30 on the storage bin 100, the problem of mismatch between the lifting position of the storage bin 100 and the height of the transfer vehicle during the crop harvesting process is solved, and the transfer efficiency can be improved. At the same time, the use of such a storage bin 100 avoids the problem of sliding downward due to excessive deadweight during the lifting and turning process of the storage bin 100, and has high safety and reliability.

[0047] It will be apparent to those skilled in the art that various modifications and variations may be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention covers modifications and variations of the present invention that fall within the scope of the appended claims and their equivalent technical solutions.
