Abstract
Description
Technical Field
[0001] This application belongs to the technical field of grain collection equipment, specifically relating to a grain bin, its cover plate, and a harvester. Background Technology
[0002] In combine harvesters, the grain bin serves as a temporary storage device for grain during the harvesting process. Currently, the grain bin consists of an open-topped body and a cover plate on top of the body. The cover plate is closable; when collecting grain, the cover plate is open, allowing the harvester operator to observe the inside of the bin from inside the cab. During rain, to prevent rainwater from entering the bin and wetting the grain, the cover plate is closed during grain collection, making it impossible to effectively assess the condition inside the bin. Utility Model Content
[0003] The purpose of this application is to provide a grain bin, its cover, and a harvester, which enables observation of the inside of the bin when the cover is closed, while preventing rainwater from entering the grain bin.
[0004] To achieve the above objectives, this application provides a grain bin cover, including a mounting component, a limiting component disposed on the side of the mounting component, and a transparent plate fixed to the mounting component by the limiting component. The mounting component is capable of sealingly connecting to the grain bin body and has a through opening communicating with the inside of the bin body, and the transparent plate covers the opening.
[0005] In some embodiments, both the mounting component and the transparent plate have multiple edges, and the limiting assembly includes a first limiting frame disposed on a first edge of the mounting component and a second limiting frame disposed on a second edge of the mounting component. The first limiting frame has a first limiting groove for the first edge of the transparent plate to be inserted, and the second limiting frame has a second limiting groove for the second edge of the transparent plate to be inserted.
[0006] In some embodiments, the first limiting frame includes a first top plate and a first bottom plate connected to each other, forming a first limiting groove between them; the second limiting frame includes a second top plate and a second bottom plate connected to each other, forming a second limiting groove between them; and both the first bottom plate and the second bottom plate are connected to the mounting component.
[0007] In some embodiments, the first limiting frame and the second limiting frame are arranged opposite to each other, the first top plate and the first bottom plate are detachably connected, and the second top plate and the second bottom plate are fixedly connected.
[0008] In some embodiments, a first drainage groove communicating with a first limiting groove is formed on the side of the first bottom plate facing the first top plate, and gaps are formed between the first top plate and the first bottom plate and the transparent plate, the gaps forming a drainage channel for water flow with the first drainage groove; and / or, a second drainage groove communicating with a second limiting groove is formed on the side of the second bottom plate facing the second top plate, and gaps are formed between the second top plate and the second bottom plate and the transparent plate, the gaps forming a drainage channel for water flow with the second drainage groove.
[0009] In some embodiments, a first elastic member is provided in the first limiting groove, the first elastic member being directly opposite the first edge of the transparent plate, and a second elastic member is provided in the second limiting groove, the second elastic member being directly opposite the second edge of the transparent plate.
[0010] In some embodiments, the limiting component further includes a clip disposed on the third side of the mounting component, the clip holding the third side of the transparent plate.
[0011] In some embodiments, the limiting component further includes a baffle disposed on the fourth side of the mounting component, the baffle being perpendicular to the transparent plate and abutting against the fourth side of the transparent plate.
[0012] A second aspect of this application provides a grain box, including a box body and the aforementioned grain box cover, the grain box cover being disposed on the box body.
[0013] A third aspect of this application provides a harvester, including a housing and the aforementioned grain bin cover, the grain bin cover being disposed on the housing; or, including the aforementioned grain bin.
[0014] The above technical solution addresses the issue that other fixing methods (such as bolt fixing) require the formation of mounting holes, which is cumbersome. Therefore, a mounting component is provided to install the transparent panel onto the box. When it rains, the transparent panel prevents rainwater from entering the box. Furthermore, due to the light transmittance of the transparent panel, the operator of the harvester can observe the situation inside the box from the cab.

[0027] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0028] Please refer to Figures 1 to 6 This application provides a grain bin cover, including a mounting component 10, a limiting component disposed on the side of the mounting component 10, and a transparent plate 30 fixed to the mounting component 10 by the limiting component. The mounting component 10 can be sealed and connected to the box body 2 of the grain bin and has a through opening communicating with the inside of the box body 2. The transparent plate 30 is covered at the opening.
[0029] When the harvester is working in the rain, the grain bin cover is placed on the grain bin. The transparent plate 30 can prevent rainwater from entering the inside of the bin 2. Furthermore, due to the light transmittance of the transparent plate 30, the operator of the harvester can observe the situation inside the bin 2 from the cab and adjust the grain harvesting operation in a timely manner.
[0030] The transparent panel 30 can be made of acrylic or glass. Since other fixing methods (such as bolt fixing) require multiple mounting holes to ensure the airtightness between the transparent panel 30 and the housing 2, the manufacturing process is complicated and disassembly is troublesome. Moreover, the space at the connection between the transparent panel 30 and the housing 2 is limited, and it is impossible to form a sufficient number of mounting holes. Therefore, the mounting component 10 and the limiting component are set. The transparent panel 30 is fixed to the housing 2 by the mounting component 10, so that the interior of the housing 2 forms a closed space. The limiting component restricts the transparent panel 30 to the opening of the mounting component 10 to prevent the transparent panel 30 from moving.
[0031] The mounting component 10 includes a square mounting frame 11 and connecting edges 12 extending horizontally along the bottom of the mounting frame 11. The mounting frame 11 can not only connect with the transparent plate 30, but also increase the height of the box 2, thereby increasing the internal volume of the box 2. The connecting edges 12 are used for sealing connection with the box 2, for example, by bolt connection. The connecting edges 12 can be four that extend horizontally along the four sides of the mounting frame 11. The size of the transparent plate 30 is larger than the size of the opening, so that the four sides of the transparent plate 30 can protrude horizontally from the four sides of the mounting frame 11. A sealing strip can be squeezed between the transparent plate 30 and the mounting frame 11 to prevent water from entering the opening and entering the interior of the box 2 through the opening.
[0032] Please refer to Figure 1 , Figures 3 to 5 In some embodiments, both the mounting component 10 and the transparent plate 30 have multiple edges. The limiting assembly includes a first limiting frame 21 disposed on the first edge of the mounting component 10 and a second limiting frame 22 disposed on the second edge of the mounting component 10. The first limiting frame 21 has a first limiting groove 211 for the first edge of the transparent plate 30 to be inserted, and the second limiting frame 22 has a second limiting groove 221 for the second edge of the transparent plate 30 to be inserted.
[0033] The first and second edges of the transparent plate 30 are respectively inserted into the first limiting groove 211 and the second limiting groove 221, restricting the transparent plate 30 from moving along the directions of its first and second edges, and simultaneously preventing the transparent plate 30 from detaching upward from the mounting component 10. Both the first limiting groove 211 and the second limiting groove 221 are U-shaped grooves, with the openings of both grooves facing the mounting component 10.
[0034] Please continue reading. Figure 1 , Figures 3 to 5 In some embodiments, the first limiting frame 21 includes a first top plate 212 and a first bottom plate 213 connected to each other, forming a first limiting groove 211 between them. The second limiting frame 22 includes a second top plate 222 and a second bottom plate 223 connected to each other, forming a second limiting groove 221 between them. The first bottom plate 213 and the second bottom plate 223 are both connected to the mounting component 10.
[0035] The relative mating positions of the first top plate 212 and the first bottom plate 213 are exactly the same as the relative mating positions of the second top plate 222 and the second bottom plate 223. For example... Figure 4 As shown, the first top plate 212 is formed in a stepped shape, and the first bottom plate 213 is formed in an "L" shape. The upper stepped part of the first top plate 212 and the horizontal part of the first bottom plate 213 near the box 2 are ( Figure 4 A first limiting groove 211 is formed between the left portion of the horizontal section of the first bottom plate 213 and the lower step portion of the first top plate 212 and the portion of the horizontal section of the first bottom plate 213 away from the box 2. Figure 4 Connect the right part of the horizontal section of the first base plate 213. (For example...) Figure 5 As shown, the second top plate 222 is formed in a stepped shape, and the second bottom plate 223 is formed in an "L" shape. The upper stepped part of the second top plate 222 and the horizontal part of the second bottom plate 223 near the box 2 are ( Figure 5 A second limiting groove 221 is formed between the right portion of the horizontal section of the second bottom plate 223 and the lower stepped portion of the second top plate 222 and the portion of the horizontal section of the second bottom plate 223 that is away from the box 2. Figure 5 (The left part of the horizontal section of the second base plate 223) is connected.
[0036] In addition, the first limiting frame 21 also includes a first reinforcing plate 215 fixed on the first base plate 213, and the second limiting frame 22 also includes a second reinforcing plate 225 fixed on the second base plate 223. Both the first reinforcing plate 215 and the second reinforcing plate 225 are trapezoidal or triangular.
[0037] Please refer to Figure 4 and Figure 5 In some embodiments, the first limiting frame 21 and the second limiting frame 22 are arranged opposite to each other, the first top plate 212 and the first bottom plate 213 are detachably connected, and the second top plate 222 and the second bottom plate 223 are fixedly connected.
[0038] Among them, the lower step portion of the first top plate 212 and the portion of the horizontal portion of the first bottom plate 213 that is away from the box body 2 ( Figure 4The right side of the horizontal portion of the first bottom plate 213 has coaxial circular holes, into which bolts 216 are inserted. The bolts 216 are locked with nuts 217, enabling a detachable connection between the first top plate 212 and the first bottom plate 213. The lower stepped portion of the second top plate 222 and the portion of the horizontal portion of the second bottom plate 223 furthest from the housing 2 (…) Figure 5 The left part of the horizontal section of the second base plate 223 can be fixedly connected by welding.
[0039] Since the first limiting frame 21 and the second limiting frame 22 respectively restrict the two opposite sides of the transparent plate 30, by setting the above connection method, when installing the transparent plate 30 onto the mounting component 10, the first top plate 212 can be removed from the first bottom plate 213, and the second side of the transparent plate 30 can be inserted into the second limiting groove 221 of the second limiting frame 22. At the same time, the first side of the transparent plate 30 is located above the first bottom plate 213. Then, the first top plate 212 is placed over the first side of the transparent plate 30, and the first top plate 212 and the first bottom plate 213 are connected with bolts 216 and nuts 217 to restrict the first side of the transparent plate 30 within the first limiting groove 211, thereby realizing the installation of the transparent plate 30.
[0040] Of course, in other embodiments, the second top plate 222 and the second bottom plate 223 can also be connected in a detachable manner.
[0041] Please continue reading. Figure 4 and Figure 5 In some embodiments, the side of the first bottom plate 213 facing the first top plate 212 has a first drainage groove 214 communicating with the first limiting groove 211. Both the first top plate 212 and the first bottom plate 213 have gaps with the transparent plate 30, and these gaps, together with the first drainage groove 214, form a drainage channel for water flow. And / or, the side of the second bottom plate 223 facing the second top plate 222 has a second drainage groove 224 communicating with the second limiting groove 221. Both the second top plate 222 and the second bottom plate 223 have gaps with the transparent plate 30, and these gaps, together with the second drainage groove 224, form a drainage channel for water flow.
[0042] When water accumulates on the surface of the transparent plate 30, such as Figure 4 As shown, water will enter the first limiting groove 211 from the gap between the first edge of the transparent plate 30 and the first top plate 212, and then fall from the edge of the first edge of the transparent plate 30 into the gap between the first edge of the transparent plate 30 and the first bottom plate 213, flowing from this gap into the first drainage groove 214, preventing water from continuing to flow into the opening of the mounting component 10 in the gap between the first edge of the transparent plate 30 and the first bottom plate 213; similarly, as Figure 5As shown, water will also enter the second limiting groove 221 from the gap between the second edge of the transparent plate 30 and the second top plate 222, and then fall from the edge of the second edge of the transparent plate 30 into the gap between the second edge of the transparent plate 30 and the second top plate 222, flowing into the second drainage groove 224 from the gap, thus preventing water from continuing to flow into the opening of the mounting component 10 in the gap between the second edge of the transparent plate 30 and the second bottom plate 223.
[0043] The first drainage channel 214 extends through both ends of the first base plate 213 in a U-shape, and extends along the first edge of the transparent plate 30; the second drainage channel 224 extends through both ends of the second base plate 223 in a U-shape, and extends along the second edge of the transparent plate 30. Multiple drainage holes are provided at the bottom of both the first and second drainage channels 214, allowing water entering the first and second drainage channels 214 to be discharged promptly through these holes.
[0044] Please continue reading. Figure 4 and Figure 5 In some embodiments, a first elastic member 23 is provided in the first limiting groove 211, and the first elastic member 23 is directly opposite the first edge of the transparent plate 30. A second elastic member 24 is provided in the second limiting groove 221, and the second elastic member 24 is directly opposite the second edge of the transparent plate 30.
[0045] With the above settings, on the one hand, when the transparent plate 30 is made of acrylic material, the transparent plate 30 will deform under the action of temperature, and the first elastic member 23 and the second elastic member 24 can undergo elastic deformation, providing movement space for the deformation of the transparent plate 30; on the other hand, when the transparent plate 30 is impacted by external force on the first elastic member 23 and the second elastic member 24, it can be buffered to avoid damage caused by hard impact.
[0046] Both the first elastic element 23 and the second elastic element 24 can be silicone strips.
[0047] Please refer to Figure 1 In some embodiments, the limiting component further includes a clip 25 disposed on the third side of the mounting component 10, the clip 25 clamping the third side of the transparent plate 30.
[0048] The clip 25 is used to restrict the movement of the transparent plate 30 along the direction of its third edge. There can be multiple clips 25, which are arranged at intervals along the extension direction of the third edge of the transparent plate 30.
[0049] Please refer to Figure 2In some embodiments, the limiting component further includes a baffle 261 disposed on the fourth side of the mounting component 10, the baffle 261 being perpendicular to the transparent plate 30 and abutting against the fourth side of the transparent plate 30.
[0050] The baffle 261 is used to restrict the movement of the transparent plate 30 along the direction of its fourth edge.
[0051] In addition, the limiting assembly includes two limiting plates 26, which are identical. Each limiting plate 26 includes a baffle 261 perpendicular to each other and a connecting plate 262. The connecting plate 262 is parallel to the transparent plate 30, and the connecting plates 262 of the two limiting plates 26 are respectively fixed on the first limiting frame 21 and the second limiting frame 22. They can be detachably connected by bolts. The baffles 261 of the two limiting plates 26 respectively block the junction of the first and fourth edges and the junction of the second and fourth edges of the transparent plate 30.
