The processing of lotus seeds requires first peeling the lotus grains (lotus seeds with shells) one by one from the lotus pod, and then shelling and peeling the lotus grains to obtain lotus seeds. Among them, the traditional method of peeling lotus grains is to first pick the lotus pods from the field, and then manually peel the lotus grains one by one from each lotus pod. The peeling efficiency is extremely low, and it consumes a large amount of human resources, which is not conducive to large-scale production by agricultural households. Content of the Utility Model

[0003] The purpose of the utility model is to provide a lotus pod granule peeling machine to solve the problems of low efficiency and time-consuming and laborious in the existing lotus pod granule peeling.

[0004] The utility model adopts the following technical solutions:

[0005] A lotus pod granule peeling machine includes a frame and a lotus pod crushing mechanism arranged on the frame. The lotus pod crushing mechanism includes a conical outer cylinder with a narrow upper part and a wide lower part and a conical inner cylinder matching the shape of the outer cylinder. The outer cylinder is fixedly connected to the frame.

[0007] Preferably, the width of the crushing channel gradually narrows from top to bottom.

[0008] More preferably, the conical structures of the outer cylinder and the inner cylinder are both composed of an upper cone and a lower cone, and the inclination outer angle of the upper cone is smaller than the inclination outer angle of the lower cone.

[0009] Further, the stirring and crushing columns are cylindrical, and external threads are provided on the outer side walls of the stirring and crushing columns.

[0010] Further, a cleaning brush is embedded in the outer cylinder and / or the side wall of the outer cylinder, and the cleaning brush extends into the crushing channel.

[0011] Furthermore, a servo motor for driving the inner cylinder to rotate is provided on the frame, a rotating bracket is fixedly welded to the inner wall of the inner cylinder, the servo motor is arranged above the feed port, and the output shaft of the servo motor passes through the inner cylinder and is fixedly connected to the rotating bracket.

[0013] Furthermore, a discharging conveyor belt is also provided on the frame, and the discharging conveyor belt is located below the discharging port.

[0014] Furthermore, it also includes a feed elevator, and the output end of the feed elevator is connected to the feed port.

[0015] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0016] 1. The Penglai crushing mechanism of the utility model utilizes inner and outer cylinders of conical structures to form a crushing channel, and crushing columns staggered on both sides of the crushing channel, and utilizes the rotation of the inner cylinder and gravity traction to crush the lotus pods in the crushing channel, thereby realizing rapid peeling of lotus seeds. The structure is simple and compact, the lotus seed peeling effect is high, and time and labor saving are achieved.

[0017] 2. The crushing channel of the utility model adopts a two-stage design that gradually narrows from top to bottom, that is, the crushing channel is divided into two sections, the upper and lower sections, by upper and lower cones. The inclination of the upper section of the crushing channel formed by the upper cone is relatively steep, while the inclination of the lower section of the crushing channel formed by the lower cone is relatively gentle. This design can make the lotus pods quickly crushed and dropped in the upper section of the crushing channel, while the lotus pod fragments pass through the lower section of the crushing channel. Since the slope of the lower section of the crushing channel is relatively gentle, the lotus pod fragments pass through the lower section of the crushing channel for a longer time and fall at a slower speed, which can be more finely crushed, thereby greatly improving the lotus seed peeling effect, and indeed the lotus seeds will not remain on the lotus pod fragments.

[0018] 3. The crushing column of the utility model adopts a cylindrical structure with external threads. With the rotation of the inner cylinder, the lotus seeds can be in a rolling state when peeling, thereby reducing the damage to the outer shell of the lotus seeds as much as possible and improving the quality of lotus seed peeling.

[0019] 4. The outer cylinder and / or the side wall of the outer cylinder of the utility model are embedded with a cleaning brush, which extends into the crushing channel and cooperates with the rotation of the inner cylinder to effectively clean the crushing channel and the crushing column to prevent the lotus pods from sticking to the crushing channel and the crushing column.

Specific embodiments

[0024] The following describes the specific embodiments of the embodiments of the present utility model with reference to the accompanying drawings.

[0025] Refer to Figure 1 and Figure 2 , a lotus pod shelling machine, including a frame 10 and a lotus pod crushing mechanism 20 provided on the frame 10. The lotus pod crushing mechanism 20 includes a conical outer cylinder 21 with a narrow upper part and a wide lower part and a conical inner cylinder 22 that matches the shape of the outer cylinder 21. The outer cylinder 21 is fixedly connected to the frame 10. The upper conical opening of the outer cylinder 21 is provided with a feed port, and the lower conical opening of the outer cylinder 21 is provided with a discharge port. A feed hopper 41 with a wide upper part and a narrow lower part and a discharge hopper 42 are respectively provided on the feed port and the discharge port. The inner cylinder 22 is rotatably arranged inside the outer cylinder 21. A crushing channel 30 is formed between the inner side wall of the outer cylinder 21 and the outer side wall of the inner cylinder 22, and the width of the crushing channel gradually narrows from top to bottom. A number of crushing columns for crushing lotus pods are alternately arranged at intervals on both sides of the crushing channel 30.

[0026] Specifically, refer to Figure 1 , in this embodiment, the frame 10 is a rectangular frame welded by square steel. The outer cylinder 21 and the inner cylinder 22 are both iron conical cylinders made of stainless steel. The outer cylinder 21 is fixedly installed inside the frame 10 by welding. The above-mentioned feed hopper 41 made of iron is welded to the upper conical opening of the outer cylinder 21, and the above-mentioned discharge hopper 42 made of iron is welded to the lower conical opening of the outer cylinder 21.

[0027] Refer to Figure 1 and Figure 2 , the upper conical opening of the inner cylinder 22 adopts a closed design. A rotating bracket 51 is provided inside the inner cylinder 22, and the rotating bracket 51 is fixedly welded to the inner side wall of the inner cylinder 22. A servo motor 50 for driving the inner cylinder 22 to rotate is also provided on the frame 10. Specifically, the servo motor 50 is fixedly mounted on the frame 10 above the feed hopper 41. The output shaft of the servo motor 50 penetrates the upper conical opening of the inner cylinder 22 and is locked and connected to the rotating bracket 51. In this embodiment, the outer cylinder 21 is fixed and does not move, and the servo motor 50 drives the rotating bracket 51 to drive the inner cylinder 22 to rotate.

[0028] Refer toFigure 2 , in this embodiment, the crushing columns include a first crushing column 23 and a second crushing column 24. The first crushing column 23 is arranged at intervals around the inner side wall of the outer cylinder 21 from top to bottom, and the second crushing column 24 is arranged at intervals around the outer side wall of the inner cylinder 22 from top to bottom. Moreover, the first crushing column 23 and the second crushing column 24 are arranged staggeredly at intervals. Thus, when the inner cylinder 22 rotates relative to the outer cylinder 21, the oppositely arranged first crushing column 23 and second crushing column 24 will not collide with each other and affect the rotation of the inner cylinder 22. In order to reduce the wear of the lotus seed shell during peeling as soon as possible, the first crushing column 23 and the second crushing column 24 in this embodiment are both cylindrical structures, and external threads are provided on the outer side walls of the first crushing column 23 and the second crushing column 24.

[0029] Referring to Figure 2 , in order to improve the effect of lotus pod peeling, in addition to adopting the design method of gradually narrowing from top to bottom, the crushing channel 30 of the present utility model also adopts a segmented design, and the crushing channel 30 is divided into upper and lower segments by upper and lower cones. Specifically, the conical structures of the outer cylinder 21 and the inner cylinder 22 are both composed of an upper cone and a lower cone. The inclined outer angle a of the upper cone is smaller than the inclined outer angle b of the lower cone. Thus, the inclination of the upper segment of the crushing channel 30 formed by the upper cone is steeper, and the inclination of the lower segment of the crushing channel 30 formed by the lower cone is gentler. This design enables the lotus pod to be quickly crushed and dropped in the upper segment of the crushing channel 30, thereby realizing the crushing of primary, rough, and large fragments; and when the lotus pod fragments pass through the lower segment of the crushing channel 30, due to the relatively gentle slope of the lower segment of the crushing channel 30, the lotus pod fragments take a longer time to pass through the lower segment of the crushing channel 30 and the dropping speed is slower. Combining with the characteristic that the crushing channel 30 changes from wide to narrow and the meshing and crushing of the crushing columns, the peeling effect of the lotus seeds can be greatly improved, ensuring that the lotus seeds will not remain on the lotus pod fragments.

[0030] Referring to Figure 1 and Figure 3 , in order to prevent the lotus pod from sticking and jamming in the crushing channel 30 and on the crushing columns, cleaning brushes 70 are embedded in the outer cylinder 21 and / or the side wall of the outer cylinder 21, and the cleaning brushes 70 extend into the crushing channel 30. In this example, it is preferably to embed the cleaning brushes 70 on the side wall of the outer cylinder 21 in a bolt-fixed manner to facilitate the replacement of the cleaning brushes 70. In addition, there can be multiple cleaning brushes 70 on the side wall of the outer cylinder 21 of the present utility model, and some of the cleaning brushes 70 can be selected to be made of steel wire. While cleaning the crushing channel, the steel brushes can also further crush the lotus pod.

[0031] Referring to Figure 1, the feeding and discharging of this lotus pod shelling machine can be manual or mechanically driven. For manual operation, only a collection box needs to be placed below the hopper, and the lotus pods are poured into the feeding hopper manually. For mechanical drive, a discharging conveyor belt 60 and a feeding elevator (not shown in the figure) need to be set on the frame 10. The discharging conveyor belt 60 is arranged below the discharging hopper 42, and the feeding elevator is arranged on one side of the frame 10, and the output end of the feeding elevator extends above the feeding hopper 41. This embodiment preferably adopts the mechanical drive mode.

[0032] Referring to Figures 1 to 2 , the working process and principle of this utility model are as follows:

[0033] First, the equipment is powered on, the servo motor 50 drives the inner cylinder 22 to rotate, and the discharging conveyor belt 60 and the feeding elevator operate; the lotus pods (preferably dried or frozen and dehydrated lotus pods) are lifted by the elevator and sent into the feeding hopper 41, and fall from the feeding hopper 41 into the upper section of the crushing channel 30, and are quickly crushed into lotus pod fragments by the rotation of the inner cylinder 22 and the interlaced crushing of the first crushing column and the second crushing column.

[0034] Subsequently, the lotus pod fragments roll and fall into the lower section of the crushing channel 30 with the rotation of the inner cylinder 22 and the traction of gravity. Through the relatively gentle lower section of the crushing channel 30 and the gradually narrowing characteristic of the crushing channel 30, and in cooperation with the crushing column, the lotus pod fragments are further crushed, so as to realize the complete peeling of the lotus seeds; and during the peeling process of the lotus seeds, due to the external thread design of the crushing column and the rotation of the inner cylinder 22, the lotus seeds can roll when being peeled, so as to minimize the damage of the outer shell of the lotus seeds and improve the quality of lotus seed shelling.

[0035] Finally, the crushed lotus pods and lotus seeds are discharged from the hopper, fall on the discharging conveyor belt 60, and are sent to the next process.

[0036] The above is only the specific implementation manner of this utility model, but the design concept of this utility model is not limited to this. Any non-substantive modification made to this utility model using this concept shall belong to the act of infringing the protection scope of this utility model.
