Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to an automatic basket changing device. Background Technology

[0002] In the development of modern agriculture, semi-automation technology for small harvesting machinery has made significant progress, but its transition to full automation still faces many challenges. Among these, the technological bottleneck of the collection system is particularly prominent, becoming one of the important factors restricting the further development of small-scale mechanization. The two existing mainstream collection methods—automatic baling and throwing, and large-capacity loader-following collection—while improving work efficiency to some extent, also have significant problems: automatic baling equipment is not only expensive but also bulky, making it difficult to adapt to the operational needs of small-scale or scattered plots; while large-capacity loaders, although capable of handling large quantities of crops, are inefficient when dealing with small plots due to their lack of flexibility. These problems not only increase farmers' operating costs but also limit the sustainability and economic benefits of agricultural production. Utility Model Content

[0003] To address the aforementioned problems, this invention provides an automatic basket-changing device that can automatically push out a full basket after collecting a full basket of crops and quickly replenish it with a new empty basket, enabling the harvesting machinery to work continuously and efficiently.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic basket changing device includes a frame, which comprises a basket storage section and a basket transport section arranged vertically. The basket storage section is located above the basket transport section and is connected to the basket transport section.

[0006] Storage basket chains are respectively provided on both sides of the storage basket section. Each storage basket chain includes storage basket sprockets and storage basket chains. Each storage basket chain has two storage basket sprockets, and the storage basket sprockets are rotatably connected to the storage basket section. The storage basket chains are sleeved on the two storage basket sprockets and are drively connected to the storage basket sprockets. Each chain buckle of the storage basket chains is provided with a locking tooth, and the locking tooth is fixedly provided on the outside of the storage basket chains so that the basket handle can be locked between the two storage basket chains. The two storage basket chains are driven by a first transmission mechanism so that the basket can move within the storage basket section.

[0007] A conveyor belt is provided on the side of the basket transport section away from the basket storage section. The conveyor belt is driven by a second transmission mechanism. When the basket moves to the end of the basket storage chain near the basket transport section through the rotation of the basket storage chain, the basket handle can disengage from the locking teeth so that the basket falls onto the conveyor belt.

[0008] The frame also includes a basket discharge section, which is located on one side of the basket transport section. The basket discharge section is rotatably equipped with several idlers, which are located on one side of the conveyor belt along the transport direction and rotate perpendicular to the transport direction of the conveyor belt. The baskets on the conveyor belt can be transported to the idlers, and the basket discharge section is equipped with a pushing mechanism to push the baskets on the idlers out of the basket discharge section.

[0009] Furthermore, a connecting shaft is fixedly threaded through the storage basket sprocket, and the two ends of the connecting shaft are respectively rotatably connected to the storage basket. A transmission sprocket is fixedly sleeved on the connecting shaft at the same end of the two storage basket chains. The first transmission mechanism is used to drive the two transmission sprockets.

[0010] Furthermore, the first transmission mechanism includes a first motor, a first drive sprocket, and a second drive sprocket. The first motor is fixedly connected to the storage basket, the first drive sprocket is fixedly connected to the output shaft of the first motor, and the first drive sprocket is connected to one of the drive sprockets via a first transmission chain.

[0011] The output shaft of the first motor is fixedly fitted with a drive gear, the storage basket is rotatably fitted with a driven shaft, the driven shaft is fixedly fitted with a driven gear that meshes with the drive gear, the second drive sprocket is fixedly fitted on the driven shaft, and the second drive sprocket is connected to another drive sprocket through a second transmission chain, so that the two drive sprockets rotate in opposite directions.

[0012] Furthermore, the conveyor belt includes drive rollers and belt body. There are two drive rollers, and the drive rollers are rotatably connected to the conveyor basket. The belt body is sleeved on the two drive rollers, and both ends of the belt body are respectively connected to the drive rollers.

[0013] Furthermore, the second transmission mechanism includes a second motor, a third drive sprocket, and a fourth drive sprocket. The second motor is fixedly connected to the basket transport unit, the third drive sprocket is fixedly connected to the output shaft of the second motor, the fourth drive sprocket is fixedly connected to one of the transmission rollers, and the fourth drive sprocket is connected to the third drive sprocket via a third transmission chain.

[0014] Furthermore, the pushing mechanism includes an electronic push rod, which is disposed on one side of the idler roller and is fixedly connected to the basket discharge section. The output section of the electronic push rod is fixedly provided with a basket discharge plate to push the basket on the idler roller out of the basket discharge section.

[0015] Furthermore, the frame is constructed by splicing together multiple support rods.

[0016] The beneficial effects of this utility model are:

[0017] 1. By engaging the handle of the basket with the teeth of two storage chains, the basket handle can be locked between the two chains, allowing multiple baskets to be stacked between them for temporary storage. Driven by a first transmission mechanism, the storage chain is rotated by a storage sprocket, causing the baskets between the chains to descend. When the bottom basket reaches the bottom of the chain, the angle of the chain links changes, guiding the bottom basket to land smoothly on the conveyor belt. The conveyor belt then transports the basket to roller 6. Once the basket is full of crops, a pushing mechanism removes the full basket. This invention automatically pushes out full baskets after harvesting and quickly replenishes them with new empty baskets. The entire process eliminates the need for manual basket changing, improving operational efficiency and reducing the labor intensity of operators. It enables harvesting machinery to work continuously and efficiently, making it particularly suitable for large-scale or long-term agricultural operations. Meanwhile, this invention features a simple structure, maintaining high performance and reliability while being more cost-competitive, helping to reduce farmers' purchase and maintenance costs and enhancing the market appeal of small agricultural machinery, thus promoting its widespread adoption. Compared to traditional large agricultural machinery, this invention fully considers space utilization efficiency, enabling the entire system to operate efficiently while occupying a smaller volume. It effectively addresses the shortcomings of outdated small machinery collection systems in the market, promoting technological advancements and market penetration of small agricultural machinery, and meeting the needs of more farmers.

[0018] 2. After the basket falls onto the conveyor belt, it is transported to the idler roller. When the basket on the idler roller is full of crops, the basket plate is pushed by the electronic push rod to push the basket out of the device so that the next basket can be placed on the conveyor belt for the next collection of crops.

[0026] Please also see Figures 1 to 3 An automatic basket changing device according to a preferred embodiment of this utility model includes a frame 1. The frame 1 includes a basket storage section 11 and a basket transport section 12 arranged vertically. The basket storage section 11 is located above the basket transport section 12, and the basket storage section 11 and the basket transport section 12 are connected. In this embodiment, the frame 1 is constructed by splicing multiple support rods 101, which has a simple structure and reduces the purchase and maintenance costs for farmers.

[0027] Storage basket chains are provided on both sides of the storage basket section 11. Each storage basket chain includes storage basket sprockets 21 and storage basket chains 22. Each storage basket chain has two storage basket sprockets 21, and the storage basket sprockets 21 are rotatably connected to the storage basket section 11. The storage basket chains 22 are sleeved on the two storage basket sprockets 21, and the storage basket chains 22 are drive-connected to the storage basket sprockets 21. Figure 2 As shown, each link of the storage basket chain 22 is provided with a locking tooth 221, and the locking tooth 221 is fixedly located on the outside of the storage basket chain 22 so that the basket handle can be engaged between the two storage basket chains; the two storage basket chains are driven by the first transmission mechanism so that the basket can move within the storage basket section 11. In this embodiment, the storage basket chain 22 is a toothed chain, so that the basket handle can be hooked on the locking tooth 211 to realize the storage of multiple stacked baskets.

[0028] like Figure 1 and Figure 3 As shown, a connecting shaft 211 is fixedly inserted through the storage basket sprocket 21. The two ends of the connecting shaft 211 are rotatably connected to the storage basket section 11. A transmission sprocket 4 is fixedly sleeved on the connecting shaft 211 at the same end of the two storage basket chains. The first transmission mechanism is used to drive the two transmission sprockets 4. In this embodiment, the transmission sprocket 4 is located at the bottom of the storage basket section 11.

[0029] The first transmission mechanism includes a first motor 41, a first drive sprocket 42, and a second drive sprocket 43. The first motor 41 is fixedly connected to the storage basket part 11, and the first drive sprocket 42 is fixedly connected to the output shaft of the first motor 41. The first drive sprocket 42 is connected to one of the drive sprockets 4 via a first transmission chain 421. In this embodiment, the first motor 41 is fixedly mounted on one side of the bottom of the storage basket part 11 via a first motor frame.

[0030] The output shaft of the first motor 41 is fixedly fitted with a drive gear 411. The storage basket part 11 is rotatably provided with a driven shaft 44. The driven shaft 44 is fixedly fitted with a driven gear 441 that meshes with the drive gear 411. The second drive sprocket 43 is fixedly fitted on the driven shaft 44, and the second drive sprocket 43 is connected to another drive sprocket 4 through a second drive chain 431 so that the two drive sprockets 4 rotate in opposite directions.

[0031] Driven by the first motor 41, the first drive sprocket 42 drives one of the transmission sprockets 4 to rotate through the first transmission chain 421, causing the storage basket chain 22 on one side to move. At the same time, since the driven gear 441 meshes with the drive gear 411, the second drive sprocket 43 drives the other transmission sprocket 4 through the second transmission chain 431, and the storage basket chain 22 on the other side moves. Moreover, the storage basket chains 22 on both sides move in opposite directions, thereby driving the basket.

[0032] like Figure 1As shown, a conveyor belt 3 is provided on the side of the basket transport section 12 away from the basket storage section 11. The conveyor belt 3 is driven by a second transmission mechanism. When the basket moves to the end of the basket storage chain near the basket transport section 12 by the rotation of the basket storage chain 22, the basket handle can disengage from the tooth 221 so that the basket falls onto the conveyor belt 3.

[0033] The frame 1 also includes a basket discharge section 13, which is located on one side of the basket transport section 12. The basket discharge section 13 is rotatably equipped with several idlers 6, which are located on one side of the conveyor belt 3 along the conveying direction and rotate perpendicular to the conveying direction of the conveyor belt 3. The baskets on the conveyor belt 3 can be transported to the idlers 6, and the basket discharge section 13 is equipped with a pushing mechanism to push the baskets on the idlers 6 out of the basket discharge section 13.

[0034] By engaging the handle of the basket with the teeth 221 of the two storage basket chains 22, the handle of the basket can be engaged between the two storage basket chains. At the same time, multiple baskets can be stacked between the two storage basket chains for temporary storage. Under the driving action of the first transmission mechanism, the storage basket sprocket 21 drives the storage basket chain 22 to rotate, causing the baskets between the two storage basket chains to descend. When the bottom basket descends to the bottom of the storage basket chain 22, the angle of the chain buckle changes and guides the bottom basket to fall smoothly onto the conveyor belt 3. Under the action of the conveyor belt 3, the basket can be transported to the idler roller 6. When the basket is full of crops, the pushing mechanism can transport the basket full of crops out.

[0035] This embodiment can automatically push out full baskets after collecting crops and quickly replenish them with new empty baskets. The entire process requires no manual basket changing, improving operational efficiency and reducing the labor intensity of operators. This allows the harvesting machinery to work continuously and efficiently, making it particularly suitable for large-scale or long-term farmland operations. Furthermore, this embodiment has a simple structure, maintaining high performance and reliability while being more cost-competitive, helping to reduce farmers' purchase and maintenance costs and enhancing the market appeal of small agricultural machinery, thus promoting its widespread adoption. Compared to traditional large agricultural machinery, this embodiment fully considers space utilization efficiency, allowing the entire system to operate efficiently while occupying a smaller volume. This effectively addresses the pain point of outdated small-scale harvesting systems in the market, promoting technological advancements and market penetration of small agricultural machinery, and meeting the needs of more farmers.

[0036] The conveyor belt 3 includes a drive roller 31 and a belt body 32. There are two drive rollers 31, and the drive rollers 31 are rotatably connected to the basket transport section 12. The belt body 32 is sleeved on the two drive rollers 31, and both ends of the belt body 32 are respectively connected to the drive rollers 31 for transmission.

[0037] The second transmission mechanism includes a second motor 5, a third drive sprocket 51 and a fourth drive sprocket 52.

The fourth drive sprocket 52 is fixedly connected to one of the transmission rollers 31, and the fourth drive sprocket 52 is connected to the third drive sprocket 51 through the third transmission chain 53.

[0038] In this embodiment, the second motor 5 is fixedly installed on one side of the top of the basket transport section 12. Under the drive of the second motor 5, the third drive sprocket 51 is driven to rotate through the third transmission chain 53, so that the corresponding transmission roller 31 rotates, thereby realizing the drive of the belt 32 to transport the basket on the belt 32.

[0039] The pushing mechanism includes an electronic push rod 7, which is disposed on one side of the idler roller 6. The electronic push rod 7 is fixedly connected to the basket discharge section 13, and the output section of the electronic push rod 7 is fixedly provided with a basket discharge plate 71 to push the basket on the idler roller 6 out of the basket discharge section 13.

[0040] In this embodiment, the electronic push rod 7 is an electric lead screw. Both ends of the electronic push rod 7 are fixedly connected to the basket discharge section 13, and the output end of the electronic push rod 7 is fixedly connected to the basket discharge plate 71. After the basket falls onto the conveyor belt 3, the basket is transported to the idler roller 6 by the conveyor belt 3. When the basket on the idler roller 6 is full of crops, the basket discharge plate 71 can be pushed by the electronic push rod 7 to push the basket out of the device so that the next basket can be placed on the conveyor belt 3 for the next collection of crops.

[0041] In this embodiment, a controller and control buttons can be provided. The controller is electrically connected to the control buttons, the first motor 41, and the second motor 5, respectively. The control buttons input control signals to the controller to realize the transportation of the basket.

[0042] The operation process of this embodiment is as follows:

[0043] The handle of the basket is engaged with the teeth 221 of the two storage basket chains 22, and multiple baskets are stacked between the two storage basket chains for temporary storage. Under the action of the first motor 41, the storage basket sprocket 21 drives the storage basket chain 22 to rotate, causing the baskets between the two storage basket chains to descend. When the bottom basket descends to the bottom of the storage basket chain 22, the angle of the chain buckle changes and guides the bottom basket to land smoothly on the conveyor belt 3. The conveyor belt 3 transports the basket to the idler roller 6, allowing the crops to be collected into the basket on the idler roller 6.

[0044] When the conveyor belt 3 transports the basket to the idler roller 6, the next basket is placed on the conveyor belt 3 under the action of the first motor 41.

[0045] Once the basket is full of crops, the electronic push rod 7 drives the basket exit plate 71, which pushes the baskets on the idler roller 6 out of the basket exit section 13. Then, the baskets on the conveyor belt 3 are transported onto the idler roller 6, thus completing one round of crop collection.
