Description

Technical Field

[0001] This application relates to the technical field of soybean processing, and in particular to a soybean roasting machine. Background Technology

[0002] In existing technologies, soybeans typically undergo washing and drying during soybean oil production. During drying, soybeans are fed into a drying oven via a loading device. However, because the hopper outlet is directly above the oven inlet, it is easily contaminated by external dust. To address this issue, existing technologies use a sliding sealing plate to block the hopper outlet. When not in use, the sealing plate can be slid to the outlet position to prevent dust from entering; when unloading is needed, workers must manually loosen the locking mechanism on the sealing plate and remove it to allow the soybeans to be discharged. However, this method requires frequent manual operation, and due to the height of the drying oven, it is cumbersome and increases the workload for workers.

[0003] The existing sealing structure uses a manual unlocking and pulling method, which effectively prevents dust from entering, but the operation is complicated, increases labor costs, and frequent mechanical operation may also increase equipment wear. In particular, during frequent operation, workers need to frequently load and unload the hopper, which is not only inconvenient but may also cause fatigue and inconvenience due to the height of the operation, affecting production efficiency and the working environment. Utility Model Content

[0004] To address the issue that existing sealing structures rely on manual unlocking and removal, which effectively prevents dust from entering, the operation is complex, increases labor costs, and frequent mechanical operation may also increase equipment wear and tear, this application provides a soybean roasting machine.

[0005] The soybean roasting machine provided in this application adopts the following technical solution: it includes a hopper, a feeding cylinder connected to the feeding port of the hopper, a sealing plate disposed at the end of the feeding cylinder away from the hopper, a counterweight support rod fixedly connected to the sealing plate, a fixed support fixedly disposed on one side of the feeding cylinder, a connecting assembly disposed at the connection between the fixed support and the counterweight support rod, and a counterweight adjusting component disposed at the end of the counterweight support rod away from the sealing plate.

[0006] By adopting the above technical solution, an automatic feeding system is realized through the cooperation of a hopper, a feeding cylinder, a sealing plate, a counterweight support rod, a fixed support, a connecting assembly, and a counterweight adjustment component. When soybeans are filled into the feeding cylinder to the point that the weight of the soybeans exceeds the weight of the counterweight adjustment component at the other end of the counterweight support rod, the counterweight support rod rotates around the fixed support under the action of the connecting assembly. This causes the sealing plate to move away from the feeding cylinder, allowing the excess soybeans in the feeding cylinder to automatically fall into the baking oven due to gravity. This process cleverly utilizes the lever principle to achieve automatic quantitative feeding of soybeans without manual intervention, greatly improving work efficiency and accuracy.

[0007] As a preferred embodiment, the outer diameter of the sealing plate is slightly larger than the inner diameter of the feeding cylinder, and the inner wall of the feeding cylinder is set as a smooth arc surface.

[0008] By adopting the above technical solution, the outer diameter of the sealing plate is designed to be slightly larger than the inner diameter of the feeding cylinder. This allows the sealing plate to fit tightly against the feeding cylinder, ensuring a sealing effect. Simultaneously, the inner wall of the feeding cylinder is designed as a smooth, rounded surface, which helps the soybeans to be automatically fed under their own weight during the falling process, reducing friction.

[0009] As a preferred embodiment, the connecting assembly includes a connecting rod fixedly disposed at one end of the counterweight support rod relative to the fixed support, a rotating shaft fixedly disposed at the connection point between the connecting rod and the fixed support, and a limiting pin disposed at the end of the rotating shaft away from the fixed support. The outer diameter of the connecting rod is smaller than the outer diameter of the rotating shaft, and the end of the connecting rod away from the counterweight support rod is tangent to the inner side of the fixed support.

[0010] By adopting the above technical solution, this design allows the connecting rod, which is fixedly installed at one end of the counterweight support rod, to be connected to the fixed support through a rotating shaft. The rotating shaft can rotate freely in the rotating hole on the fixed support. This connection method between the connecting rod and the rotating shaft allows the counterweight support rod to rotate relative to the fixed support.

[0011] As a preferred embodiment, the rotating shaft passes through the fixed support and is connected to the limiting pin, and the fixed support is provided with a rotating hole that is adapted to the rotating shaft.

[0012] By adopting the above technical solution, the counterweight support rod can rotate flexibly relative to the fixed support by means of a connecting rod and a rotating shaft fixedly installed at one end of the counterweight support rod, and a limiting pin installed at the other end of the rotating shaft and connected to the fixed support.

[0013] As a preferred embodiment, the counterweight adjustment component includes an adjustment part disposed at the end of the counterweight support rod away from the sealing plate, a limiting block connected to the adjustment part, and a counterweight block connected to the adjustment part. The outer periphery of the adjustment part is uniformly provided with external threads. The limiting block and the counterweight block are respectively connected to the adjustment part through threaded structures, and the limiting block is disposed at the end of the counterweight support rod away from the sealing plate.

[0014] By adopting the above technical solution, the limiting block can easily limit the counterweight block and prevent the counterweight block from slipping off the counterweight support rod;

[0015] As a preferred embodiment, it also includes anti-slip protrusions respectively disposed on the outer periphery of the counterweight, the anti-slip protrusions being arranged circumferentially with the center of the counterweight as the center point.

[0016] By adopting the above technical solution, anti-slip ridges are set on the outer periphery of the counterweight, and these ridges are evenly distributed around the center of the counterweight. The presence of the anti-slip ridges significantly increases the friction between the counterweight and the operator's hand, making it easier and more stable for the operator to move or adjust the counterweight.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. By using a connecting rod and a rotating shaft fixedly mounted at one end of the counterweight support rod, and a limiting pin connected to a fixed support at the other end of the rotating shaft, flexible rotation of the counterweight support rod relative to the fixed support is achieved. Specifically, when the rotating shaft passes through the rotating hole on the fixed support and connects to the limiting pin, the limiting pin effectively restricts excessive movement of the rotating shaft, ensuring that it can only rotate around the rotating hole. This design allows the counterweight support rod to rotate freely relative to the fixed support.

[0019] 2. An adjusting part is installed at the end of the counterweight support rod furthest from the sealing plate. The adjusting part has evenly distributed external threads on its outer circumference, allowing the limiting block and the counterweight block to connect to the adjusting part via the threaded structure. This facilitates the connection of the counterweight block to the counterweight support rod. The limiting block, located at the end of the counterweight support rod furthest from the sealing plate, limits the counterweight block's position, preventing it from slipping. By rotating the counterweight block, its position on the counterweight support rod can be adjusted, thereby adjusting the load-bearing capacity of the sealing plate and thus regulating the amount of soybeans stored in the feeding cylinder. This process is not only convenient and quick but also ensures stability and accuracy during adjustment. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This application discloses a soybean roasting machine. It includes a hopper 1, a feeding cylinder 11 connected to the feeding port of the hopper 1, a sealing plate 2 disposed at the end of the feeding cylinder 11 away from the hopper 1, a counterweight support rod 4 fixedly connected to the sealing plate 2, a fixed support 3 fixedly disposed on one side of the feeding cylinder 11, a connecting assembly disposed at the connection point between the fixed support 3 and the counterweight support rod 4, and a counterweight adjustment component disposed at the end of the counterweight support rod 4 away from the sealing plate 2. In this utility model, an automatic feeding system is realized through the cooperation of the hopper 1, the feeding cylinder 11, the sealing plate 2, the counterweight support rod 4, the fixed support 3, the connecting assembly, and the counterweight adjustment component. When soybeans are filled into the feeding cylinder 11 to the point that their weight exceeds the weight of the counterweight adjustment component at the other end of the counterweight support rod 4, the counterweight support rod 4 rotates around the fixed support 3 under the action of the connecting assembly. This causes the sealing plate 2 to move away from the feeding cylinder 11, allowing the excess soybeans in the feeding cylinder 11 to automatically fall into the baking oven due to gravity. This process cleverly utilizes the lever principle to achieve automatic quantitative feeding of soybeans without manual intervention, greatly improving work efficiency and accuracy.

[0028] Please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A soybean roasting machine includes a hopper 1, a feeding cylinder 11 connected to the feeding port of the hopper 1, and a sealing plate 2 disposed at the end of the feeding cylinder 11 away from the hopper 1. To facilitate sealing of the feeding cylinder 11 by the sealing plate 2, the outer diameter of the sealing plate 2 is slightly larger than the inner diameter of the feeding cylinder 11, and the inner wall of the feeding cylinder 11 is designed as a smooth arc surface. The design of the sealing plate 2's outer diameter being slightly larger than the inner diameter of the feeding cylinder 11 allows the sealing plate 2 to fit tightly against the feeding cylinder 11, ensuring a good seal. Simultaneously, the smooth arc surface of the inner wall of the feeding cylinder 11 helps the soybeans to be automatically fed due to their own weight during the falling process, reducing friction.

[0029] Please refer to the details. Figure 2 , Figure 3 , Figure 4 and Figure 5 The counterweight support rod 4 is fixedly connected to the sealing plate 2, the fixed support 3 is fixedly set on one side of the feed cylinder 11, and the connecting assembly is set at the connection between the fixed support 3 and the counterweight support rod 4. The connecting assembly includes a connecting rod 41 fixedly set at one end of the counterweight support rod 4 relative to the fixed support 3, a rotating shaft 411 fixedly set at the connection between the connecting rod 41 and the fixed support 3, and a limiting pin 4111 set at the end of the rotating shaft 411 away from the connection with the fixed support 3. The outer diameter of the connecting rod 41 is smaller than the outer diameter of the rotating shaft 411, and the end of the connecting rod 41 away from the connection with the counterweight support rod 4 is tangent to the inner side of the fixed support 3. This design allows the connecting rod 41 fixedly set at one end of the counterweight support rod 4 to be connected to the fixed support 3 through the rotating shaft 411. The rotating shaft 411 rotates freely in the rotating hole on the fixed support 3. This connection method of the connecting rod 41 and the rotating shaft 411 allows the counterweight support rod 4 to rotate relative to the fixed support 3.

[0030] Please refer to the details. Figure 1 , Figure 4 and Figure 5 The rotating shaft 411 passes through the fixed support 3 and connects with the limiting pin 4111. The fixed support 3 is provided with a rotating hole adapted to the rotating shaft 411. Through the connecting rod 41 and the rotating shaft 411 fixedly installed at one end of the counterweight rod 4, and the limiting pin 4111 connected to the fixed support 3 at the other end of the rotating shaft 411, the counterweight rod 4 can rotate flexibly relative to the fixed support 3. Specifically, when the rotating shaft 411 passes through the rotating hole on the fixed support 3 and connects with the limiting pin 4111, the limiting pin 4111 effectively restricts the excessive movement of the rotating shaft 411, ensuring that it can only rotate around the rotating hole. This design allows the counterweight rod 4 to rotate freely relative to the fixed support 3. During this process, the limiting function of the limiting pin 4111 ensures the freedom of rotation while preventing overall failure due to loosening of the rotating shaft 411, thus ensuring the safety and reliability of the system.

[0031] Please refer to the details. Figure 2 , Figure 3 , Figure 4 and Figure 5 A counterweight adjustment component is provided at the end of the counterweight support rod 4 away from the end connected to the sealing plate 2. The counterweight adjustment component includes an adjustment part 42 at the end of the counterweight support rod 4 away from the end connected to the sealing plate 2, a limiting block 51 connected to the adjustment part 42, and a counterweight block 52 connected to the adjustment part 42. The outer periphery of the adjustment part 42 is uniformly provided with external threads. The limiting block 51 and the counterweight block 52 are respectively connected to the adjustment part 42 through the thread structure. The limiting block 51 is located at the end of the counterweight support rod 4 away from the end of the sealing plate 2. The limiting block 51 facilitates the limiting of the counterweight block 52 and prevents the counterweight block 52 from slipping off the counterweight support rod 4.

[0032] Please refer to the details. Figure 4 An adjusting part 42 is provided at the end of the counterweight support rod 4 away from the sealing plate 2. The adjusting part 42 has uniformly distributed external threads on its outer circumference, allowing the limiting block 51 and the counterweight block 52 to be connected to the adjusting part 42 via the threaded structure. This facilitates the connection of the counterweight block 52 to the counterweight support rod 4. The limiting block 51 is located at the end of the counterweight support rod 4 away from the sealing plate 2, serving to limit the counterweight block 52 and prevent it from slipping. By rotating the counterweight block 52, its position on the counterweight support rod 4 can be adjusted, thereby adjusting the load-bearing capacity of the sealing plate 2 and thus regulating the amount of soybeans stored in the feeding cylinder 11. This process is not only convenient and quick but also ensures stability and accuracy during adjustment.

[0033] Please refer to the details. Figure 4 and Figure 5 To facilitate adjustment of the counterweight 52, anti-slip protrusions are also included on the outer periphery of the counterweight 52. These anti-slip protrusions are circumferentially arranged with the center of the counterweight 52 as the center point, and are evenly distributed around the center of the counterweight 52. The presence of these anti-slip protrusions significantly increases the friction between the counterweight 52 and the operator's hand, making it easier and more stable for the operator to move or adjust the counterweight 52.

[0034] The implementation principle of a soybean roasting machine according to an embodiment of this application is as follows: During use, soybeans enter the feeding cylinder 11 through the hopper 1. The load-bearing capacity of the sealing plate 2 is adjusted by rotating the counterweight block 52 on the outer periphery of the counterweight support rod 4. When the amount of soybeans stored on the sealing plate 2 is greater than the load-bearing capacity of the counterweight support rod 4, the connecting rod 41 fixedly set at one end of the counterweight support rod 4 is connected to the fixed support 3 through the rotating shaft 411. The rotating shaft 411 rotates freely in the rotating hole on the fixed support 3. This connection method of the connecting rod 41 and the rotating shaft 411 allows the counterweight support rod 4 to rotate relative to the fixed support 3, thereby opening the sealing plate 2 and allowing the soybeans in the feeding cylinder 11 to be fed into the roasting chamber due to their own weight.

[0035] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
