Description

Technical Field

[0001] This utility model relates to the field of grain storage technology for corn harvesters, specifically a multi-functional grain storage for a self-propelled corn harvester. Background Technology

[0002] The grain hoppers on self-propelled corn harvesters are generally tilting hoppers, which are rotated by hydraulic cylinders to unload the grain. Currently, the structure of existing grain hoppers on the market is relatively uniform, generally an integrated unit with a guide flap on one side of the top, resulting in a simple structure. The grain hopper is mainly used to hold corn ears, while the fallen corn kernels need to be collected by a separate pipe inside the hopper, which is inconvenient. When the corn ears fall from the guide flap onto the transport vehicle, they mostly fall into the middle of the transport vehicle's grain hopper, causing the corn ears to accumulate high in the middle of the hopper, making it impossible to achieve even distribution.

[0003] To address this, based on our practical production experience, we designed a new type of multi-functional grain silo. A separate grain storage silo was designed on one side of the traditional grain silo, and corresponding grain drop openings were opened on the side wall of the silo to collect corn kernels. At the same time, a diversion plate was designed in the middle of the grain guide flap, so that when the grain silo is discharging, the corn ears can fall evenly from both sides of the grain guide flap into the grain hopper of the transport vehicle, avoiding the problem of excessive accumulation and uneven distribution of corn ears in the middle of the grain hopper, thus improving operational efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional grain bin for a self-propelled corn harvester to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-functional grain bin for a self-propelled corn harvester includes a grain bin, a grain guide flap on one side of the grain bin, outer baffles on both sides of the grain guide flap, a grain storage bin on one side of the grain bin, a grain dropping port communicating with the grain storage bin on the inner wall of the grain bin, an openable and closable grain baffle on the grain dropping port, and a diversion plate in the middle of the grain guide flap.

[0007] As a further preferred embodiment of this utility model: an expansion door is movably provided on the side of the grain silo away from the grain storage silo to expand the volume of the grain silo.

[0008] As a further preferred embodiment of this utility model: a first hydraulic cylinder is hinged inside the grain storage bin, and the output end of the first hydraulic cylinder passes through the grain discharge port and is hinged to the grain baffle plate.

[0009] As a further preferred embodiment of this utility model: a particle-blocking telescopic cloth is provided on one side of the particle-blocking plate, and one end of the particle-blocking telescopic cloth is connected to the particle discharge port.

[0010] As a further preferred embodiment of this utility model: the top of the expansion door is hinged to the grain silo, and two guide rail plates are symmetrically arranged at the bottom of the grain silo. A movable shaft that can slide along the guide rail plate is provided on the guide rail plate, and a grain-blocking bottom plate is hinged on the movable shaft. One end of the grain-blocking bottom plate is hinged to the bottom of the expansion door. A tassel-blocking telescopic cloth is provided on both sides of the expansion door, and one end of the tassel-blocking telescopic cloth is connected to the grain silo. A second hydraulic cylinder for driving the opening and closing of the expansion door is provided on the grain silo.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0019] Please see Figure 1-4 This embodiment provides a multi-functional grain bin for a self-propelled corn harvester, including a grain bin 1. A grain guide flap 6 is provided on one side of the grain bin 1, and outer baffles 8 are provided on both sides of the grain guide flap 6. It should be noted that, as a common design in Changshu, the grain baffle 6 and the grain bin 1 are generally movably connected. When the grain bin 1 is not flipped, the grain baffle 6 is in a vertical state. When the grain bin 1 is flipped to discharge material, the grain baffle 6 rotates to a state parallel to the side wall of the grain bin 1, which facilitates the falling of corn ears. A grain storage bin 2 is provided on one side of the grain bin 1. As is common knowledge, when corn kernels fall from the harvester into the grain bin 1, they fall closer to the grain guide flap 6. Therefore, as is a conventional operation familiar to those skilled in the art, the grain storage bin 2 should be located below the grain guide flap 6. A grain drop opening 3 communicating with the grain storage bin 2 is provided on the inner wall of the grain bin 1. An openable and closable grain baffle 4 is provided on the grain drop opening 3. Specifically, a first hydraulic cylinder 5 is hinged inside the grain storage bin 2. The output end of the first hydraulic cylinder 5 passes through the grain drop opening 3 and is hinged to the grain baffle 4. Preferably, two first hydraulic cylinders 5 can be provided, which is a conventional design and will not be described in detail. It should be noted that, as is a conventional arrangement familiar to those skilled in the art, the bottom of the grain baffle 4 should be hinged to the grain drop opening 3, and a grain-blocking telescopic cloth 15 is provided on one side of the grain baffle 4, with one end of the grain-blocking telescopic cloth 15 connected to the grain drop opening 3. When the deflector plate 4 is opened, it can guide the corn kernels into the grain storage bin 2; when the grain storage bin 2 is full of corn kernels, the deflector plate 4 can be closed, and the corn kernels will fall into the grain bin 1.

[0020] It should be further noted that, as a standard feature, the bottom of the side wall of the grain storage bin 2 should be equipped with a corresponding discharge port or discharge door for discharging corn kernels. This is a standard design and will not be elaborated further.

[0021] To ensure that the corn cobs fall evenly into the grain hopper during discharge, a diversion plate 7 is installed in the middle of the grain guide flap 6, so that the corn cobs fall into the grain hopper from both sides of the grain guide flap 6, thus avoiding the problem of excessive accumulation of corn cobs in the middle of the grain hopper.

[0022] Furthermore, such as Figure 1-4As shown, an expansion door 9 is movably installed on the side of the grain silo 1 away from the grain storage silo 2 to expand the volume of the grain silo 1. Specifically, the top of the expansion door 9 is hinged to the grain silo 1. Two guide rail plates 14 are symmetrically arranged at the bottom of the grain silo 1. A movable shaft 13 that can slide along the guide rail plate 14 is provided on the guide rail plate 14. A grain-blocking bottom plate 12 is hinged to the movable shaft 13. One end of the grain-blocking bottom plate 12 is hinged to the bottom of the expansion door 9. Ear-blocking telescopic cloths 11 are provided on both sides of the expansion door 9 to prevent corn ears from falling between the expansion door 9 and the grain silo 1. As a conventional design, one end of the ear-blocking telescopic cloth 11 should be connected to the grain silo 1. A second hydraulic cylinder 10 is provided on the grain silo 1 to drive the opening and closing of the expansion door 9. It should be noted that, depending on the requirements, the second hydraulic cylinder 10 can be located inside the grain silo 1 or outside the grain silo 1. A symmetrical design is preferred. Its two ends should be hinged to the grain silo 1 and the expansion door 9 respectively. As a conventional design, this application will not elaborate further.

[0023] It should be further noted that, as a conventional setting familiar to those skilled in the art, the maximum angle of the expansion door 9 should be limited to avoid the grain blocking bottom plate 12 being affected by the bottom plate of the grain silo 1. The design can be based on the requirements, and this application will not elaborate further.

[0024] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0025] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
