Description

Technical Field

[0001] This application relates to the field of shell fruit processing equipment, and in particular to a device for dehulling and separating Eucommia ulmoides winged fruit. Background Technology

[0002] Eucommia ulmoides winged fruit is an oval-shaped winged seed with a shell in the middle of the wing containing the kernel. Because the inner wall of the shell is densely covered with filaments rich in eucommia gum, it is quite tough and difficult to peel off. On the other hand, since eucommia gum is also a valuable rubber raw material, the outer shell of the winged fruit must be removed during the shelling process while trying not to damage the filaments and keeping them in a clump-like state to ensure the extraction rate of eucommia gum later.

[0003] Patent document CN114009800B discloses an automatic shelling and separation system for Eucommia ulmoides winged fruit, including a vibrating feeder, a collector, a sorting feeder, a shelling machine, and a shell screening machine. The shelling machine is used to crush the shell of the Eucommia ulmoides winged fruit and separate it from the fruit inside. The shelling machine is equipped with shelling teeth and an adjustable pressure plate to remove the shell of the Eucommia ulmoides winged fruit. The effect is obvious and has certain positive significance. However, there are also some shortcomings. For example, the Eucommia ulmoides winged fruit conveyed by the spiral conveyor belt in the storage tank is conveyed one by one. Therefore, the Eucommia ulmoides winged fruit entering the shelling machine will also be crushed and shelled one by one. The efficiency is low and it cannot be automated for large-scale shelling.

[0025] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0026] like Figure 1-7 As shown, a device for dehulling and separating Eucommia ulmoides winged fruit includes a first crushing chamber 100. The chamber wall 1 of the first crushing chamber 100 is provided with mesh holes for the Eucommia ulmoides winged fruit to fall off. A crushing frame is rotatably mounted inside the first crushing chamber 100. A mounting plate 12 is mounted on the crushing frame. An arc-shaped pressure plate 13 is connected to one side of the mounting plate 12. The end of the arc-shaped pressure plate 13 away from the mounting plate 12 is elastically connected to the mounting plate 12. A first crushing zone 101 is formed between the arc-shaped pressure plate 13 and the chamber wall 1 of the first crushing chamber 100. Along the rotation direction of the crushing frame, the distance between the arc-shaped pressure plate 13 and the chamber wall 1 gradually decreases.

[0027] In this Eucommia ulmoides winged fruit dehulling and separation device, the first crushing chamber 100 is the core area of ​​the entire dehulling process.

[0028] The mesh provided on the cavity wall 1 of the first crushing chamber 100 plays a key role. When the Eucommia ulmoides winged fruit enters the first crushing chamber 100 for dehulling, the fruit inside will fall out through these meshes when it is squeezed and crushed, thus achieving the initial separation of the fruit from the outer shell.

[0029] The rotating crushing frame inside the first crushing chamber 100 is the power source for shell removal, and the mounting plate 12 on the crushing frame provides the mounting base for the arc-shaped pressure plate 13. The arc-shaped pressure plate 13 is ingeniously designed, with one end elastically connected to the mounting plate 12. This elastic connection allows the arc-shaped pressure plate 13 to have a certain buffering and self-adaptive ability when it comes into contact with and is squeezed by the Eucommia ulmoides winged fruit.

[0030] The first crushing zone 101, formed between the arc-shaped pressure plate 13 and the cavity wall 1 of the first crushing chamber 100, is the place where the Eucommia ulmoides winged fruit undergoes initial crushing. Along the rotation direction of the crushing frame, the distance between the arc-shaped pressure plate 13 and the cavity wall 1 gradually decreases. This design ensures that after the Eucommia ulmoides winged fruit enters the first crushing zone 101, the compressive force gradually increases as the crushing frame rotates, thus more effectively crushing the outer shell of the Eucommia ulmoides winged fruit. Simultaneously, this gradually increasing compressive force also helps reduce damage to the gum filaments on the inner wall of the fruit shell, maintaining the filaments in a clump-like state and improving the subsequent extraction rate of Eucommia ulmoides gum.

[0031] The arc-shaped pressure plate 13 has a certain elasticity. The side of the arc-shaped pressure plate 13 facing the wall 1 of the first crushing chamber 100 is provided with a protrusion 130 to increase the friction on the Eucommia ulmoides wing fruit.

[0032] The mounting plate 12 and the arc-shaped pressure plate 13 can be arranged in multiple sets circumferentially in the first crushing chamber 100.

[0033] Compared with traditional dehulling devices, the dehulling and separation device provided in this application can continuously crush a large number of Eucommia ulmoides winged fruits, thereby effectively improving dehulling efficiency.

[0034] In some further embodiments, the top of the first crushing chamber 100 is provided with a feed inlet 10, and the feed inlet 10 is provided with a feed hopper 2.

[0035] The addition of the feed hopper 2 expands the receiving area of ​​the feed inlet 10, making it easier for operators to pour Eucommia ulmoides winged fruits into the device. It also facilitates connection with upstream conveying equipment (such as conveyor belts) for automated feeding. In actual use, a large number of Eucommia ulmoides winged fruits can quickly and stably enter the first crushing chamber 100 through the feed hopper 2, improving the feeding efficiency of the entire dehulling and separation device and reducing manual operation time and labor intensity.

[0036] In some further embodiments, the crushing frame includes a rotating shaft 11 and a mounting frame 110. The mounting frame 110 is connected to the rotating shaft 11. A slot 120 is provided on the mounting plate 12. The slot 120 is arranged radially along the rotating shaft 11. The slot 120 and the mounting plate 12 are connected by bolts.

[0037] The slot 120 on the mounting plate 12 is radially arranged along the rotating shaft 11, and the slot 120 is connected to the mounting plate 12 by bolts. This adjustable structural design allows the position of the arc-shaped pressure plate 13 on the mounting plate 12 to be adjusted according to actual needs. For example, when processing Eucommia ulmoides winged fruits of different sizes, the distance between the arc-shaped pressure plate 13 and the cavity wall 1 of the first crushing chamber 100 can be changed by adjusting the position of the bolts in the slot 120, thereby adapting to the shelling requirements of Eucommia ulmoides winged fruits of different sizes and improving the versatility and adaptability of the device.

[0038] In some further embodiments, the mounting plate 12 is provided with two connecting holes spaced apart, the arc-shaped pressure plate 13 is connected with a spring 14, the other end of the spring 14 passes through the connecting hole and is connected to the connecting plate 7, the connecting plate 7 is screwed with an adjusting bolt 71, the mounting plate 12 is provided with a guide post 70 on the side facing away from the arc-shaped pressure plate 13, the connecting plate 7 is provided with a guide hole, and the guide post 70 slides with the guide hole.

[0039] By rotating the adjusting bolt 71, the compression degree of the spring 14 can be changed, thereby adjusting the pressure between the arc-shaped pressure plate 13 and the wall 1 of the first crushing chamber 100. The cooperation between the guide post 70 and the guide hole ensures the stability of the connecting plate 7 during movement, allowing the arc-shaped pressure plate 13 to move smoothly under pressure, ensuring the stability and reliability of the shelling process. In actual production, the pressure of the arc-shaped pressure plate 13 can be flexibly adjusted according to the hardness, toughness, and other characteristics of different batches of Eucommia ulmoides winged fruit to achieve the best shelling effect.

[0040] In some further embodiments, the bottom of the first crushing chamber 100 is provided with a discharge port 15, and the lower part of the discharge port 15 is connected to the second crushing chamber 3. The second crushing chamber 3 is provided with two sets of extrusion conveyor belts 42, and the two sets of extrusion conveyor belts 42 are arranged on the side facing each other to form the second crushing chamber 3.

[0041] The discharge port 15 at the bottom of the first crushing chamber 100 and the connected second crushing chamber 3 below it further refine the shelling process of Eucommia ulmoides winged fruit. After initial shelling in the first crushing chamber 100 (at this point, some of the Eucommia ulmoides winged fruit may still be partially shelled or the outer shell may still be attached to the fruit), the fruit enters the second crushing chamber 3 through the discharge port 15. The two sets of extrusion conveyor belts 42 in the second crushing chamber 3 form a second crushing zone with their surfaces facing each other. The Eucommia ulmoides winged fruit is subjected to extrusion between the two sets of extrusion conveyor belts 42, further separating the remaining outer shell from the fruit. This dual crushing design greatly improves the thoroughness of shelling, ensuring that the Eucommia ulmoides winged fruit can be fully shelled and improving the shelling quality.

[0042] In some further embodiments, the extrusion conveyor belt 42 is fitted on the drive roller 60 and the driven roller 61, and the drive roller 60 is rotatably mounted on the frame 5; the frame 5 is provided with an arc-shaped adjustment hole 610, and a bearing seat is slidably provided in the arc-shaped adjustment hole 610, and the driven roller 61 is rotatably engaged with the bearing seat.

[0043] The position of the driven roller 61 can be changed by adjusting the position of the bearing seat in the arc-shaped adjusting hole 610, thereby adjusting the distance between the two sets of extrusion conveyor belts 42. When processing Eucommia ulmoides winged fruits of different sizes or with different degrees of shelling, the spacing of the extrusion conveyor belts 42 can be flexibly adjusted to achieve the best extrusion shelling effect. For example, for Eucommia ulmoides winged fruits that are not completely shelled, the spacing of the extrusion conveyor belts 42 can be appropriately reduced to increase the extrusion force and improve the shelling efficiency.

[0044] The bearing housing can be locked to the adjustment hole using bolts and nuts. When adjustment is required, the bolts and nuts can be removed. After adjustment is completed, the bearing housing can be fixed to the different connecting holes on the edge of the arc-shaped adjustment hole 610 using bolts and nuts.

[0045] Both sets of extrusion conveyor belts 42 move downwards on the side closest to each other, with the conveying speed of one set of extrusion conveyor belts 42 being greater than that of the other set.

[0046] In some further embodiments, the outer side of the extrusion conveyor belt 42 is provided with raised strips.

[0047] During the operation of the extrusion conveyor belt 42, the convex strips can better grasp the Eucommia ulmoides winged fruit, so that it is subjected to more effective extrusion between the two sets of extrusion conveyor belts 42, preventing the Eucommia ulmoides winged fruit from slipping during the extrusion process, thereby improving the shelling effect and efficiency.

[0048] In some further embodiments, the second crushing chamber 3 includes an upper chamber 43 and a lower chamber 40, with the extrusion conveyor belt 42 located in the lower chamber 40; both the upper chamber 43 and the lower chamber 40 are provided with an air inlet and an air outlet, with the air inlet connected to a blower to blow the crushed shell away from the air outlet.

[0049] During the shelling process, a blower blows air into the upper chamber 43 and lower chamber 40 through the air inlet, blowing the broken shells away from the air outlet. This air-separation method effectively separates the broken shells from the fruit, avoiding the problem of incomplete separation that may exist in traditional separation methods, and improving the efficiency and purity of separation. At the same time, the air-separation process is relatively gentle and will not cause secondary damage to the fruit, ensuring the integrity of the fruit.

[0050] In some further embodiments, the bottom of the lower cavity 40 is provided with a discharge cavity 41.

[0051] During the air separation process, the fruit falls into the discharge chamber 41 at the bottom of the lower chamber 40 under the action of gravity, facilitating subsequent collection and processing. The design of the discharge chamber 41 makes the structure of the entire shelling and separation device more reasonable, realizing the integrated operation of shelling, separation and collection, improving production efficiency and facilitating large-scale automated production.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
