Description

Technical Field

[0001] This utility model relates to the technical field of harvester storage devices, and in particular to a discharge device for a harvester storage hopper. Background Technology

[0002] Harvesters dig crops out of fields and transport them to storage hoppers or similar containers via a conveyor system, achieving both harvesting and centralized storage. The front end of the harvester's conveyor system connects to the digging mechanism to receive the harvested crops. The rear end of the conveyor system can typically rotate and adjust its angle. When no crops need to be fed into the storage hopper, the rear end rotates upwards to prevent crops from falling directly onto the conveyor and into the hopper; conversely, it rotates downwards. This structural characteristic of the conveyor system necessitates a certain amount of space between the storage hopper and the conveyor system during installation. Insufficient space can lead to interference and collisions between the conveyor system and the storage hopper during rotation, while excessive space can cause crops to detach from the hopper during transport. Using electric lifting or other devices to actively move the corresponding sidewalls of the storage hopper to maintain the distance between the conveyor system and the storage hopper would significantly increase costs and render it impractical. Utility Model Content

[0005] Preferably, the baffle is connected to the top end of the guide rod, the bottom end of the guide rod is inserted into the guide hole on the bottom surface of the feed port, and a spring is sleeved on the guide rod. The two ends of the spring press against the baffle and the bottom surface of the feed port respectively, and the baffle can be reset upward by the elastic force of the spring.

[0006] Preferably, a top plate is connected to the top side of the baffle, the top end of the guide rod is connected to the top plate, and the top end of the spring extends to the lower surface of the top plate.

[0014] This invention uses a baffle to block the space between the bottom of the conveying device and the feed inlet on the side wall of the storage hopper. When the end of the conveying device is facing upwards, the baffle automatically stays at a high position, acting as part of the side wall of the storage hopper to block the crop. When the end of the conveying device rotates downwards, the baffle is pressed down from a high position to a low position. During the pressing process, the top side of the baffle and the bottom side of the conveying device remain in contact, so there is no excessive gap and the crop will not fall out of the storage hopper during conveying. The passive pressing method of the baffle can avoid interference and collision with the storage hopper, and it does not require electric lifting or other devices to control the active movement of the side wall of the storage hopper corresponding to the conveying device. It is low in cost and can be achieved by elastic devices such as springs in actual use. It is highly practical and easy to promote and apply. Attached Figure Description

[0022] Referring to the attached diagram, the specific implementation method is as follows:

[0023] like Figure 1-4 As shown, a discharge device for a harvester storage hopper includes a storage hopper 2. A section of the side wall of the storage hopper 2 is provided with a feeding port and a baffle 3 that can block the lower half of the feeding port. The end of the conveying device 1 passes through the upper half of the feeding port. When the end of the conveying device 1 rotates downward from the upward position, the baffle 3 can be pressed down from the high position to the low position by the conveying device 1. When the end of the conveying device 1 returns to the upward position from the downward position, the baffle 3 can automatically rise from the low position and stay at the high position.

[0024] In this embodiment, the top side of the storage hopper 2 is open, and the conveying port extends from the middle of a section of the side wall of the storage hopper 2 to the top side. The end of the conveying device 1 is located above the storage hopper 2, and the bottom side of the end of the conveying device 1 is... Figure 5 , 6 The conveying position shown occupies the space in the upper half of the conveying port, at which point the baffle 3 also descends. In addition to the structure of this embodiment, the storage hopper 2 can also be provided with an end cap on the top side to form a top-sealed structure.

[0025] like Figure 2 , 4 As shown, a top plate 4 is connected to the top side of the baffle 3. The top plate 4 is a long rectangular plate. The top plate 4 is located on the side of the baffle 3 facing the outside of the storage hopper 2. The width of the top plate 4 is not greater than the thickness of the side wall of the storage hopper 2. The top plate 4 is connected to the top of three guide rods 5 respectively. The three guide rods 5 are evenly spaced along the length of the top plate 4. The bottom end of the guide rod 5 is inserted into the guide hole on the bottom surface of the feed port. A spring 6 is sleeved on the guide rod 5. The two ends of the spring 6 press against the baffle 3 and the bottom surface of the feed port respectively. The elastic force of the spring 6 allows the baffle 3 to be reset upward.

[0026] like Figure 2 , 4 As shown, the top plate 4 is provided with pressure rollers 7 at both ends along its length. The end of the conveying device 1 can simultaneously press against the two pressure rollers 7. The pressure rollers 7 can roll on the bottom surface of the end of the conveying device 1 as the conveying device 1 rotates, thus achieving... Figure 6 The position ensures that the baffle 3 and the top plate 4 will not collide or interfere with the end of the conveying device 1 throughout the entire process.

[0027] like Figure 2 , 4 As shown in Figure 6, the pressure roller 7 is sleeved on the axle 8, the axle 8 passes through the support, and the support is installed on the upper surface of the top plate 4. Guide grooves 9 are respectively opened on both sides of the feed port along the length direction. The axles 8 of the two pressure rollers 7 extend into the two guide grooves 9 respectively. The length direction of the guide grooves 9 is parallel to the length direction of the guide rod 5, and both are set vertically. Therefore, the guide grooves 9 and the guide rod 5 can cooperate to guide the lifting and lowering movement of the baffle 3.

[0028] In this embodiment, when the end of the conveying device 1 is in an upward position, the baffle 3 can automatically stay at a high position, acting as part of the side wall of the storage hopper 2 to block the crops. When the end of the conveying device 1 rotates downward, the baffle 3 can be pressed down from the high position to the low position by the conveying device 1. Pressing down means that the top side of the baffle 3 is in contact with the bottom side of the conveying device 1, so there will be no excessive gap and the crops will not fall out of the storage hopper 2 during conveying. The passive pressing down of the baffle 3 can avoid interference and collision with the storage hopper 2, and there is no need for electric lifting or other devices to control the active movement of the side wall of the storage hopper 2 corresponding to the conveying device 1. It is low in cost and highly practical.
