Description

Technical Field

[0001] The utility model relates to the technical field of bean sprout production, in particular to an automatic bean dropping device for bean sprout production. Background Art

[0002] When producing bean sprouts, in order to ensure the quality and yield of bean sprouts, the number of beans required for production needs to be adjusted according to the size of the germination equipment or container. Since different containers (such as wooden barrels, seedling trays, special germination machines, etc.) can accommodate different numbers of beans, the factory needs to adjust the amount of beans per portion according to the container capacity.

[0003] At present, the way to control the amount of beans is mostly manual weighing. Before bean sprouts are produced, workers will determine the amount of beans according to the germination container, then weigh out multiple portions of beans, and then put each portion of beans in a container for germination. Since the factory's bean sprout production volume is large, if each portion of beans is weighed manually, this will not only increase the workers' workload, but also be inefficient. Therefore, in order to solve the above problems, it is urgent to propose an automatic bean dropping device for bean sprout production. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model aims to provide an automatic bean dropping device for bean sprout production, so as to achieve quantitative dropping of each portion of beans.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The invention discloses an automatic bean-dropping device for bean sprout production, comprising a frame, a loading box is fixed on the frame, a discharge tray is rotatably connected to the frame, an arc-shaped feeding hole is opened on the discharge tray, a discharge pipe is connected to the loading box, a discharge end of the discharge pipe is against the upper side of the discharge tray, when the discharge tray rotates, the discharge end of the discharge pipe can pass through the arc of the feeding hole, so that the discharge pipe is continuously connected with the feeding hole.

[0007] Principle of the utility model:

[0008] In this scheme, the loading box is used to hold the beans. In the initial state, the discharge tray blocks the discharge end of the discharge pipe, and the beans will not fall out. When the discharge tray rotates, the discharge end of the discharge pipe passes through the arc of the feeding hole, and the discharge pipe is connected with the feeding hole. At this time, the beans will fall into the feeding hole from the discharge pipe. Since the feeding hole is arc-shaped, the discharge pipe will continue to be connected with the feeding hole for a period of time during the rotation of the discharge tray. During this period of time, the beans continue to be discharged. After the discharge end of the discharge pipe completely passes through the feeding hole, the discharge tray blocks the discharge pipe again, and the beans stop being discharged.

[0009] When using this solution, the discharge tray rotates continuously, and the discharge pipe is intermittently connected to the feeding hole, thereby realizing intermittent feeding. By adopting the intermittent feeding method, it can be ensured that after loading a portion of beans, time is left to place the next empty container to load the next portion of beans, which is convenient to use. By setting the feeding hole to an arc shape, the discharge pipe can be continuously connected to the feeding hole during the rotation of the discharge tray, allowing the beans to be continuously discharged. Since the arc length of the feeding hole is fixed, the discharge pipe is connected to the feeding hole for the same time, that is, the amount of beans discharged each time is the same, thereby realizing quantitative dropping of each portion of beans.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] With the cooperation of the arc-shaped feeding hole and the discharge pipe, this solution can realize intermittent quantitative feeding, without the need for manual weighing of beans, which can greatly reduce the workload of workers. At the same time, the intermittent feeding method can reserve time for placing empty containers for the next bean loading, ensure the continuity of material receiving, improve the efficiency of the entire production line, and is highly practical.

[0012] As a preferred embodiment of the utility model, one side of the feed hole is slidably connected with an arc-shaped adjustment plate that matches the feed hole. The adjustment plate slides along the arc of the feed hole, and the adjustment plate can slide into the feed hole to block the feed hole. In this solution, during the sliding of the adjustment plate along the arc of the feed hole, the adjustment plate can block part of the arc length of the feed hole. By changing the arc length, the connection time between the discharge pipe and the feed hole can be changed, thereby changing the discharge time. Under the condition of the same discharge speed, the discharge amount can be adjusted by adjusting the discharge time. By changing the position of the adjustment plate, the discharge amount of beans each time can be controlled. This setting can adjust the amount of beans per portion according to the capacity of different containers to adapt to different actual production situations, and has strong applicability.

[0013] As a preferred embodiment of the utility model, the discharge tray is provided with a first slide groove in cooperation with the adjustment plate, the first slide groove is connected with the material passing hole, a lever is fixed to one end of the adjustment plate away from the material passing hole, a second slide groove is provided on the side wall of the discharge tray in cooperation with the lever, the second slide groove is connected with the first slide groove and the outside, and the lever is slidably connected in the second slide groove. When using this solution, by shifting the lever, the lever can drive the adjustment plate to slide along the arc of the material passing hole, the structure is simple, and the adjustment is convenient.

[0014] As a preferred embodiment of the utility model, the upper edge of the feeding hole is a slope, and the lower side of the slope is in contact with the adjustment plate. In this solution, the adjustment plate is slidably arranged on one side of the feeding hole, and there is a step between the adjustment plate and the upper side of the feeding hole. When the discharge pipe passes through the feeding hole, the beans in the discharge pipe may be stuck at the position of the step, resulting in an unsmooth sliding between the discharge pipe and the discharge tray. By setting the upper edge of the feeding hole as a slope, this solution can guide the beans in the discharge pipe when the discharge pipe passes through the feeding hole, thereby improving the sliding smoothness between the discharge pipe and the discharge tray.

[0015] As a preferred embodiment of the utility model, a receiving hopper is provided below the discharge tray, and the receiving port of the receiving hopper corresponds to the right below the discharge end of the discharge pipe. In this solution, the receiving port of the receiving hopper is provided right below the discharge end of the discharge pipe, and when the material passing hole of the discharge tray rotates and connects with the discharge end, the receiving hopper can just catch the beans.

[0016] As a preferred embodiment of the utility model, a conveyor belt is provided below the receiving hopper, a feeding box is placed on the conveyor belt, a cloth cover is detachably connected to the lower side of the receiving hopper, and the beans in the receiving hopper fall from the cloth cover into the feeding box. By providing the cloth cover, on the one hand, the beans can be guided to prevent the beans from scattering around after falling out of the higher receiving hopper, and on the other hand, the flexibility of the cloth cover can slow down the falling speed of the beans, thereby reducing the bouncing amplitude of the beans when they fall into the bottom of the feeding box, further preventing the beans from scattering.

[0024] See also Figure 1 As shown, this embodiment discloses an automatic bean dropping device for bean sprout production, including a frame, a loading box 1 for containing beans is fixed on the frame, a discharge pipe 11 is connected to the lower side of the loading box 1, and a discharge tray 2 is rotatably connected to the frame. Specifically, a motor is installed on the frame, and the output end of the motor is connected to the rotating shaft of the discharge tray 2 through a reducer, and the discharge tray 2 rotates slowly. An arc-shaped feeding hole 21 is provided on the discharge tray 2, and the discharge end of the discharge pipe 11 is against the upper side of the discharge tray 2. When the discharge tray 2 rotates, the discharge end of the discharge pipe 11 can pass through the arc of the feeding hole 21, so that the discharge pipe 11 is continuously connected with the feeding hole 21. When the discharge pipe 11 is connected with the feeding hole 21, the beans will fall into the feeding hole 21 from the discharge pipe 11. During this period of time, the beans are continuously discharged until the discharge end of the discharge pipe 11 completely passes through the feeding hole 21, and the discharge tray 2 covers the discharge pipe 11 again, and the beans stop being discharged.

[0025] See also Figure 3 As shown, one side of the feeding hole 21 is slidably connected with an arc-shaped adjusting plate 22 that matches the feeding hole 21. The adjusting plate 22 slides along the arc of the feeding hole 21. The adjusting plate 22 can slide into the feeding hole 21 to cover the feeding hole 21. The adjusting plate 22 is used to adjust the amount of beans discharged each time. Specifically, an arc-shaped first slide groove 24 is provided in the discharge tray 2 to cooperate with the adjusting plate 22. The first slide groove 24 is connected with the feeding hole 21. A lever 23 is fixed to one end of the adjusting plate 22 away from the feeding hole 21. A arc-shaped second slide groove 25 is provided on the side wall of the discharge tray 2 to cooperate with the lever 23. The second slide groove 25 connects the first slide groove 24 with the outside world. The free end of the lever 23 passes through the second slide groove 25, and the lever 23 is slidably connected in the second slide groove 25. When using this solution, by moving the lever 23, the lever 23 drives the adjustment plate 22 to slide along the arc of the feeding hole 21. During the sliding process of the adjustment plate 22, the adjustment plate 22 can block part of the arc length of the feeding hole 21. By changing the arc length, the connection time between the discharge pipe 11 and the feeding hole 21 can be changed, thereby changing the discharge time. Under the condition of the same discharge speed, the discharge amount can be adjusted by adjusting the discharge time. This setting can adjust the amount of beans per portion according to different container capacities to adapt to different actual production situations, and has strong applicability.

[0026] The upper edge of the feeding hole 21 is a slope 26, and the lower side of the slope 26 is in contact with the adjustment plate 22. By setting the upper edge of the feeding hole 21 as the slope 26, the beans in the discharging pipe 11 can be guided when the discharging pipe 11 passes through the feeding hole 21, so that the sliding between the discharging pipe 11 and the discharging tray 2 is smoother.

[0027] See also Figure 1 and Figure 2 As shown, a receiving hopper 3 is provided below the discharge tray 2, and the receiving hopper 3 is fixed on the frame. The receiving port of the receiving hopper 3 corresponds to the discharge end of the discharge pipe 11. A conveying structure is also provided on the frame, and the conveying structure includes a conveyor belt 5, and the conveyor belt 5 is located below the receiving hopper 3. A feeding box 6 is placed on the conveyor belt 5. The feeding box 6 is sequentially conveyed to the bottom of the receiving hopper 3 through the conveyor belt 5. When the feeding box 6 reaches the bottom of the receiving hopper 3, the discharge tray 2 just rotates to the position where the feeding hole 21 is connected to the discharge pipe 11, and normal material discharge begins at this time. When the material discharge is completed, the feeding box 6 filled with beans is continuously conveyed to the next process. Among them, the lower side of the receiving hopper 3 is detachably connected with a cloth cover 4. Specifically, hooks 31 are fixed on both sides of the lower part of the receiving hopper 3, and holes are opened on both sides of the cloth cover 4 and hooked on the hooks 31. By providing the cloth cover 4, the beans can be guided to prevent the beans from scattering after falling out of the receiving hopper 3. At the same time, the flexibility of the cloth cover 4 can slow down the falling speed of the beans, thereby reducing the bouncing amplitude of the beans when they fall into the bottom of the feeding box 6, further preventing the beans from scattering.

[0028] Specific implementation process:

[0029] When using this solution, it is necessary to first determine the amount of beans for each portion according to the germination container, and adjust the position of the adjustment plate 22 by toggling the lever 23 to adjust the discharge amount of each portion of beans. After the position of the adjustment plate is determined, the discharge can be started. During the discharge process, the discharge tray 2 continues to rotate, and the discharge pipe 11 will be intermittently connected with the feed hole 21. When the discharge pipe 11 is moved above the feed hole 21, the discharge pipe 11 is connected with the feed hole 21, and the beans fall from the discharge pipe 11 into the feed hole 21, and then fall into the feeding box 6. After the discharge pipe 11 completely passes through the feed hole 21, at this time, the discharge tray 2 covers the discharge pipe 11 again, and the beans stop being discharged, and the discharge is completed.

[0030] After the material dropping is completed, the feeding box 6 filled with beans is conveyed to the next process, and the next empty container is further conveyed to the bottom of the receiving hopper 3 to load the next portion of beans. During this process, the discharge tray 2 continues to rotate. When the feeding box 6 reaches the bottom of the receiving hopper 3, the discharge tray 2 just rotates to the position where the material hole 21 is connected to the discharge pipe 11, and then the next round of material dropping begins.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
