Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically a grain unloading device for a harvester. Background Technology

[0002] Harvesters, as an indispensable piece of equipment in modern agricultural production, greatly improve the efficiency and effectiveness of agricultural production. As an agricultural machinery, harvesters are mainly used in the harvesting process of crops. They integrate multiple functions such as cutting, conveying, threshing, separating, and cleaning, and can efficiently complete the entire process from harvesting crops in the field to separating and cleaning grains. When the grain in the granary accumulates to a certain amount, the harvester's unloading system is used to discharge the grain from the granary and transport it to a designated location or container.

[0003] The existing equipment unloads grain through unloading cans. However, when it is necessary to control the unloading speed, the existing equipment cannot control the unloading speed according to the requirements, which can easily lead to grain spillage and waste.

[0004] Therefore, those skilled in the art have provided a harvester unloading device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a harvester unloading device to solve the problems mentioned in the background art.

[0010] As a further improvement of this invention: a grain outlet hole is provided at the bottom of the inner wall of the grain unloading frame, and a grain outlet pipe is fixedly connected to the bottom of the grain outlet hole. A grain unloading cylinder is rotatably connected inside the grain outlet pipe, and the grain unloading cylinder is connected to the grain outlet pipe. The angle of the grain unloading cylinder is adjustable, allowing the device to adapt to grain receiving equipment of different heights and angles. This design enhances the flexibility of the grain unloading process, making the unloading operation more convenient and efficient, improving unloading efficiency, and shortening unloading time.

[0011] As a further improvement of this utility model: a transmission motor is fixedly connected to the bottom of the grain unloading frame, and a connecting shaft is fixedly connected to the transmission end of the transmission motor.

[0012] As a further embodiment of this utility model: a small gear is fixedly connected to the bottom of the connecting shaft two, and a large gear is meshed with the other side of the small gear, and the large gear is sleeved on the side surface of the unloading cylinder.

[0013] As a further embodiment of this utility model: the diameters of the first rotating shaft and the second rotating shaft are the same, and both the first and the second blocking plates have protruding parts and are arranged alternately up and down.

[0014] As a further improvement of this utility model: the diameter of the grain outlet hole is slightly smaller than the diameter of the grain outlet pipe, and the shape of the grain unloading cylinder is an inverted Z-shape.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By installing the grain unloading assembly, operators can easily control the forward and reverse rotation of the servo motor, thereby quickly adjusting the position of the baffle plate. This ensures a stable flow of grain during unloading, preventing waste caused by excessively fast or slow speeds. The baffle plate position can be quickly adjusted as needed to precisely regulate the unloading speed, avoiding grain spillage and waste caused by excessively fast unloading and improving the efficiency and accuracy of grain unloading.

[0017] 2. The adjustable angle of the unloading hopper allows the device to adapt to grain receiving equipment at different heights and angles. This design enhances the flexibility of the unloading process, making unloading operations more convenient and efficient, improving unloading efficiency, and shortening unloading time.

[0024] 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.

[0025] Example 1

[0026] Reference Figure 1 - Figure 5This embodiment provides a harvester unloading device, including an unloading frame 1 and an unloading assembly 2. The unloading assembly 2 is disposed on one side of the unloading frame 1 and includes an L-shaped plate 201 fixedly connected to one side of the unloading frame 1. A servo motor 202 is fixedly connected to the other side of the L-shaped plate 201. A connecting shaft 203 is fixedly connected to the transmission end of the servo motor 202. A gear 204 is fixedly connected to the other side of the connecting shaft 203. A rotating shaft 205 is fixedly connected to the other side of the gear 204. A blocking plate 206 is fixedly sleeved on the side surface of the rotating shaft 205. A gear 207 is meshed with the other side of the gear 204. A rotating shaft 208 is fixedly connected to the side, and a baffle plate 209 is fixedly sleeved on the side surface of the rotating shaft 208. When rapid grain unloading is required, the servo motor 202 is started, which drives the gear 204 to rotate through the connecting shaft 203. The gear 204 meshes with the gear 207. The rotating shaft 205 and the rotating shaft 208 respectively drive the baffle plate 206 and the baffle plate 209 to move away from each other to the maximum, so that the grain quickly passes through the grain outlet hole 9 into the grain outlet pipe 10, and is then unloaded from the grain unloading cylinder 11. When the grain bag is almost full, the operator can control the servo motor 202 to reverse, so that the baffle plate 206 and the baffle plate 209 slowly move closer together, reducing the speed of grain flow and preventing grain from spilling.

[0027] Example 2

[0028] Reference Figure 1 - Figure 3This embodiment is based on the previous embodiment, but differs in that a grain storage silo 3 is fixedly connected to the other side of the unloading frame 1. A filter screen 4 is fixedly connected inside the grain storage silo 3. An installation plate 5 is fixedly connected to the other side of the grain storage silo 3. A rotary motor 6 is fixedly connected to the top of the installation plate 5. A rotating shaft 7 is fixedly connected to the transmission end of the rotary motor 6. An auger 8 is fixedly connected to the side surface of the rotating shaft 7. A grain outlet hole 9 is opened at the bottom of the inner wall of the unloading frame 1. A grain outlet pipe 10 is fixedly connected to the bottom of the grain outlet hole 9. A grain unloading cylinder 11 is rotatably connected inside the grain outlet pipe 10. The grain unloading cylinder 11 communicates with the grain outlet pipe 10. A transmission motor 12 is fixedly connected to the bottom of the unloading frame 1. A connecting shaft 13 is fixedly connected to the transmission end of the transmission motor 12. A small gear 14 is fixedly connected to the bottom of the connecting shaft 13. A large gear 15 is meshed on the other side of the small gear 14. The large gear 15 is sleeved on the side surface of the grain unloading cylinder 11. The diameters of the rotating shaft 1 205 and the rotating shaft 2 208 are the same. The baffle plate 1 206 and the baffle plate 2 209 both have protruding parts and are arranged alternately up and down. The diameter of the grain outlet hole 9 is slightly smaller than the diameter of the grain outlet pipe 10. The grain unloading cylinder 11 is shaped like an inverted Z. When in use, the grain storage bin 3 is filled with grain. When unloading is required, the grain is filtered by the filter screen 4, and the impurities are left on the filter screen 4. The pure grain continues to flow downward. The rotating motor 6 is started. The rotating motor 6 drives the auger 8 to rotate through the rotating shaft 7. The auger 8 pushes the grain in the grain storage bin 3 to one side, so that it enters the grain unloading frame 1. At the same time, the transmission motor 12 is started. The transmission motor 12 drives the small gear 14 to rotate through the connecting shaft 2 13. The small gear 14 meshes with the large gear 15. The small gear 14 drives the large gear 15 to rotate, so that the grain unloading cylinder 11 starts to rotate, thereby adjusting the angle of the grain unloading cylinder 11 horizontally. After the adjustment is completed, the transmission motor 12 is turned off.
