Description

Technical Field

[0001] This utility model belongs to the field of sweet potato deep processing technology, and in particular relates to a size sorting device for sweet potato deep processing. Background Technology

[0002] Sweet potatoes, also known as yams, are not only edible but also have very high medicinal value. They also have a high yield per acre. After the sweet potatoes mature, in order to extend their shelf life and to increase the diversity of food, they are further processed into sweet potato flour, sweet potato strips, dried sweet potatoes, etc. Before further processing, the sweet potatoes need to be sorted and selected according to different sizes.

[0003] In existing technologies, sweet potato sorting mainly relies on manual operation, which not only results in inaccurate size judgment and easy confusion, but also leads to slow sorting speed, low efficiency, and increased workload. Therefore, there is an urgent need to overcome and improve the existing technology. This paper provides a high-efficiency size sorting device for deep processing of sweet potatoes. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reasonably designed, simple, automatic, fast, and efficient size sorting device for deep processing of sweet potatoes, which makes the work easier and solves the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A size sorting device for deep processing of sweet potatoes includes a sorting box. Multiple feed inlets are vertically spaced on the front outer wall of the sorting box. Several lifting plates, arranged at a higher front and lower rear angle, are vertically spaced on the front of the sorting box. The lifting plates are driven to rise and fall by two sets of drive components located on the left and right outer sides of the sorting box. Multiple sets of protective plates, corresponding one-to-one with the feed inlets, are fixedly installed on the right outer wall of the sorting box. Two protective plates are symmetrically arranged in each set, and a limiting rod is fixedly installed at the end of each protective plate furthest from the sorting box. Multiple sets of transmission components for outputting sweet potatoes are installed on the inner side of the sorting box, corresponding to the feed inlets. A second motor is fixedly installed on the top left rear outer wall of the sorting box, and a worm gear is fixedly connected to the output end of the second motor. The multiple transmission components are linked together through the worm gear.

[0007] Preferably, the width of the multiple feed ports increases sequentially from bottom to top, and the length of the multiple sets of transmission components decreases sequentially from bottom to top.

[0008] Preferably, the drive assembly includes a chain, an upper sprocket, a lower sprocket, and a first motor. The upper sprocket is engaged with the inner top of the chain, and the lower sprocket is engaged with the inner bottom of the chain. The lower sprocket bearing is mounted on the bottom side wall of the sorting box. The first motor is fixedly mounted on the top of the sorting box, and the output shaft of the first motor is fixedly connected to the upper sprocket.

[0009] Preferably, several lifting plates are equidistantly arranged between the two chains along their length, and the two ends of each lifting plate are welded and fixed to the left and right chains respectively.

[0010] Preferably, the upper end face of the transmission component is located below the corresponding bottom end face of the feed inlet.

[0011] Preferably, the transmission assembly includes a transmission belt, a left belt roller, a right belt roller, and a worm gear. The left belt roller is installed on the inner side of one end of the transmission belt, and the right belt roller is installed on the inner side of the other end of the transmission belt. The right belt roller bearing is installed between the front and rear protective plates. The left belt roller bearing is installed on the inner side of the left end of the sorting box, and the worm gear is fixedly connected to the rear end of the left belt roller.

[0012] Preferably, the worm gear meshes with the worm, and there is a gap between the transmission belt and the corresponding limiting rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, sweet potatoes are simply placed manually on the inclined lifting plate at the bottom front of the sorting box. When the first motor is started to control the chain to drive at a constant speed, the lifting plate can move the sweet potatoes upwards. The width of the three feed inlets increases sequentially from bottom to top. When the sweet potatoes move to the feed inlet that matches their size, they can roll under gravity and enter the corresponding feed inlet. This enables automatic size sorting, making sorting more accurate and efficient, while also reducing workload. Furthermore, this device can be used in combination with existing conveyors on the market for even better results.

[0015] This invention allows sweet potatoes to fall through the feed inlet onto the corresponding conveyor belt. Starting the second motor controls the worm gear to rotate, which in turn drives the left belt roller to rotate at a constant speed. With the cooperation of the right belt roller, the conveyor belt starts transporting the sorted sweet potatoes to the right for easy retrieval by staff. The use of protective plates and limit rods prevents sweet potatoes from falling from heights and causing damage. Attached Figure Description

[0025] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

The front of the sorting box 1 has several lifting plates 4 arranged at a vertical angle with the front higher than the rear. The two ends of the lifting plates 4 are driven to rise and fall by two sets of drive components 3 located on the left and right sides of the sorting box 1, respectively. The right outer wall of the sorting box 1 is fixedly installed with multiple sets of protective plates 5 corresponding to the multiple feed ports 2. Two protective plates 5 are arranged symmetrically in front and behind each other. The end of each set of protective plates 5 away from the sorting box 1 is fixedly provided with a limiting rod 6. The inner side of the sorting box 1 is equipped with multiple sets of transmission components 7 for outputting sweet potatoes, corresponding to the multiple feed ports 2. The top left rear outer wall of the sorting box 1 is fixedly installed with a second motor 8. The output end of the second motor 8 is fixedly connected to a worm gear 9. The multiple sets of transmission components 7 are linked together through the worm gear 9.

[0027] As a preferred embodiment, based on the above structure, the widths of the multiple feed ports 2 are arranged to increase sequentially from bottom to top, and the lengths of the multiple sets of transmission components 7 are arranged to decrease sequentially from bottom to top.

[0028] In this embodiment, multiple feed inlets 2 with increasing width from bottom to top facilitate the sorting of sweet potatoes of different sizes.

[0029] In a preferred embodiment, based on the above structure, the drive assembly 3 further includes a chain 31, an upper sprocket 32, a lower sprocket 33, and a first motor 34. The upper sprocket 32 ​​is engaged with the inner top side of the chain 31, and the lower sprocket 33 is engaged with the inner bottom side of the chain 31. The lower sprocket 33 is bearing-mounted on the bottom side wall of the sorting box 1. The first motor 34 is fixedly mounted on the top of the sorting box 1, and the output shaft of the first motor 34 is fixedly connected to the upper sprocket 32.

[0030] As a preferred embodiment, based on the above structure, a plurality of lifting plates 4 are arranged at equal intervals along the length direction between the two chains 31, and the two ends of each lifting plate 4 are welded and fixed to the left and right chains 31 respectively.

[0031] In this embodiment, by starting the first motor 34, the chain 31 is controlled to start uniform speed transmission, which can control the inclined lifting plate 4 to drive the sweet potato placed on it to move vertically upward. When the sweet potato moves to the feed port 2 that matches its size, the sweet potato can roll under the action of gravity and enter the corresponding feed port 2, which can realize automatic size sorting and make sorting more accurate.

[0032] As a preferred embodiment, based on the above structure, the upper end face of the transmission component 7 is located below the bottom end face of the corresponding feed inlet 2.

[0033] In this embodiment, the worm gear 9 facilitates the synchronous operation of multiple sets of transmission components 7, making it convenient to retrieve the sorted sweet potatoes.

[0034] In a preferred embodiment, based on the above structure, the transmission assembly 7 further includes a transmission belt 71, a left belt roller 72, a right belt roller 73, and a worm gear 74. The left belt roller 72 is installed on the inner side of one end of the transmission belt 71, and the right belt roller 73 is installed on the inner side of the other end of the transmission belt 71. The right belt roller 73 bearing is installed between the front and rear protective plates 5, and the left belt roller 72 bearing is installed on the inner side of the left end of the sorting box 1. The worm gear 74 is fixedly connected to the rear end of the left belt roller 72.

[0035] As a preferred embodiment, based on the above structure, the worm gear 74 meshes with the worm 9, and there is a gap between the transmission belt 71 and the corresponding limiting rod 6.

[0036] In this embodiment, the use of the protective plate 5 and the limiting rod 6 can prevent the sweet potato from falling from a height and being damaged.

[0037] The working principle of this utility model is as follows:

[0038] In use, firstly, the first motor 34 and the second motor 8 are turned on. Workers can place the sweet potatoes to be sorted on the inclined lifting plates 4 at the bottom front of the sorting box 1. When the first motor 34 controls the upper sprocket 32 ​​to rotate, the lower sprocket 33, in conjunction with it, controls the chain 31 to drive several lifting plates 4 at a slow and uniform speed. Since the width of the three feed inlets 2 increases sequentially from bottom to top, when the lifting plates 4 move the sweet potatoes upwards, when the sweet potatoes move to the feed inlet 2 that matches their size, they can roll under gravity and enter the feed inlet 2. Similarly, automatic size sorting of sweet potatoes can be achieved. Compared to manual sorting, this device sorts more accurately, is less prone to confusion, and has higher sorting efficiency and speed, while also reducing workload. Figure 6 As shown in the figure, this device can also be used in combination with existing conveyors on the market to slowly and orderly transport sweet potatoes to the top of the lifting plate 4, with better results;

[0039] Once the sweet potato enters the feed inlet 2 corresponding to its size, it will fall onto the corresponding conveyor belt 71. The second motor 8 can control the worm gear 9 to rotate, and through the worm wheel 74, it can control the left belt roller 72 to rotate at a constant speed. With the cooperation of the right belt roller 73, it can control the conveyor belt 71 to start the transmission, so that the sweet potato above can be stably transported to the right for easy picking by the staff. Moreover, the setting of the protective plate 5 and the limit rod 6 can intercept the sweet potato that is about to reach the right end of the conveyor belt 71, so as to prevent the sweet potato from falling from a height due to the staff not picking it up in time, and prevent the sweet potato from being cracked or damaged.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
