Description

Technical Field

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

[0002] Sprouting frames, also commonly known as sprout baskets, sprout trays or planting trays, are containers specially designed for seed germination and seedling growth, and are particularly suitable for indoor sprouting or growing small vegetables and herbs. These frames or trays provide an ideal environment for seed germination and growth. Before distributing the beans needed for producing bean sprouts to the sprouting frames, the bean bags containing the beans are first soaked in water, and then the soaked beans are evenly spread on the bottom of the sprouting frames. According to the needs of the bean seeds, an appropriate amount of natural light or artificial light is provided to promote their growth. When the bean sprouts grow to a certain height or reach an ideal growth stage, they can be harvested for consumption or transplanted into larger containers.

[0003] Currently, soaked beans are usually spread manually into the sprouting frame, and the beans are spread manually while being spread, which not only has a high labor intensity for workers, but also has a low efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is that, in view of the above-mentioned defects, an automatic bean-feeding device for bean sprout production is provided, which can not only automatically distribute the beans to each sprout frame without manual distribution, but also ensure that the beans in each sprout frame are distributed more evenly to avoid affecting the growth of the bean sprouts.

[0005] The technical solution adopted by the utility model to solve the technical problem is: an automatic bean-feeding device for bean sprout production, comprising a frame, a conveyor belt for conveying sprout frames and a turntable rotatably installed on the frame are provided on the frame, a feeding barrel for placing bean bags is provided above the conveyor belt, the upper surface of the turntable is in contact with the lower side of the feeding barrel, a feeding port is provided on the turntable, a discharge port is provided at the bottom of the discharge barrel, the feed port on the turntable driven by a driving mechanism is aligned with or completely misaligned with the discharge port on the discharge barrel, and a screen is provided below the turntable.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: in the initial state, the feeding port on the turntable and the discharging port on the lower barrel are in a completely misaligned state, and a germination frame is provided directly below the lower barrel. When the beans need to be distributed to different germination frames, the soaked bean bag is first placed with the opening facing downward into the lower barrel, and after placement, the turntable is driven to rotate by the driving mechanism to align the feeding port with the discharging port, and the beans in the bean bag pass through the discharging port and the feeding port and fall onto the screen, and the beans fall into the germination frame more evenly with the vibration of the screen. At the same position, avoid the beans from piling up at the same position in the germination frame, thereby avoid affecting the normal growth of bean sprouts. After a certain number of beans are distributed to the germination frame, the driving mechanism controls the turntable to rotate back to the initial state, and the feeding port and the discharging port are completely misaligned, so that the beans no longer fall down. Then the conveyor belt moves, driving the germination frame to move. After the next germination frame is located directly below the discharge barrel, the above steps are repeated, thereby automatically distributing the beans more evenly to each germination frame without manual distribution, saving manpower and improving efficiency.

[0007] As a preferred embodiment of the utility model, a plurality of the feed openings are spaced apart along the circumference of the turntable, the diameter of each feed opening increases successively and the diameter of the discharge opening is larger than the diameter of the largest feed opening.

[0008] The beneficial effects of this solution are as follows: different sizes of sprouting frames can cultivate different numbers of beans. Since a plurality of feeding ports with different diameters are arranged at intervals along the circumference of the turntable, the feeding ports with different diameters on the turntable can be selected and aligned with the discharge port according to the specific sizes of the sprouting frames in different batches, thereby distributing the beans into the sprouting frames and improving the utilization rate of the sprouting frames.

[0009] As a preferred embodiment of the utility model, clamping blocks for clamping the two ends of the bean bag are respectively provided on the two inner side walls arranged opposite to each other of the discharge barrel.

[0010] The beneficial effect of this solution is that after the bean bag is placed in the feeding barrel, the two ends of the bean bag are clamped by the clamping blocks to prevent the bean bag from sliding downward as the beans are reduced and unable to maintain a vertical state, which affects the feeding of the beans.

[0011] As a preferred embodiment of the utility model, a connecting part is detachably connected to the frame, and the connecting part includes connecting frames detachably connected to both sides of the frame, and the sides of the two connecting frames close to each other are respectively provided with fixing sleeves for placing the unloading barrel, and the fixing sleeves are fixedly connected to the connecting frames through connecting blocks, and the screen is installed between the two connecting frames. The driving mechanism includes a motor assembly installed on the connecting blocks along the vertical direction, and the output shaft of the motor assembly is connected to the turntable.

[0012] The beneficial effects of this solution are as follows: the connecting part is used to install the feed barrel, the driving mechanism, the turntable and the screen; the connecting part is detachably connected to the frame; when there is no need to distribute beans into the germination frame, the connecting part can be disassembled so that the conveyor belt can be used for other purposes; the feed barrel is installed on the connecting frame through a fixing sleeve; when there is no need to distribute beans into the germination frame, the feed barrel can be removed from the fixing sleeve to facilitate cleaning of the feed barrel.

[0013] As a preferred embodiment of the utility model, a connecting block is provided between each fixing sleeve and the connecting frame, one of the connecting blocks is provided with a mounting hole in the vertical direction, and the driving mechanism includes a motor assembly installed on the upper side of the connecting block in the vertical direction, and the output shaft of the motor assembly passes through the mounting hole and is connected to the turntable.

[0014] The beneficial effects of this solution are as follows: the connecting block between the connecting piece and the fixing sleeve is used to install the motor assembly, the output shaft of the motor assembly passes through the mounting hole and is connected to the turntable, the rotation of the motor assembly drives the output shaft to rotate, and the rotation of the output shaft drives the turntable to rotate, thereby realizing the control of the discharge of beans. Compared with setting the motor assembly below the turntable, setting the motor assembly above the turntable is more reasonable in structure and can avoid the motor assembly from affecting the trajectory of the falling beans.

[0015] As a preferred embodiment of the utility model, the discharge port is located on one side of the bottom of the lower barrel close to the turntable, the inner side of the bottom of the lower barrel is an upwardly inclined inclined surface, and the lower end of the inclined surface is connected to the discharge port.

[0016] The beneficial effects of this solution are as follows: the inner side of the bottom of the lower barrel is inclined upward and the lower end of the inclined surface is connected to the discharge port. When distributing beans into the germination frame, the beans in the bean bag in the lower barrel are gathered to the discharge port along the inclined surface, avoiding the accumulation of beans in the lower barrel, thereby avoiding blockage and waste of raw materials.
