DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-1 To Attachment Figure 2-6 Embodiments of the present application are described in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0027] In the description of the present application, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like are used to indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The present application relates to a husk separation device, which includes a drum mechanism and a feeding mechanism 1000, wherein the feeding mechanism 1000 provides materials to an outer drum 2100 of the drum mechanism, and the drum mechanism separates the pulp and husk of the materials. For example, broken pistachios or betel nuts cut into two halves are put into the drum mechanism to separate the husk and the pulp.

[0030] As an implementation method, in combination with the attached Figure 1-3 The feeding mechanism 1000 includes a feeding lifting and conveying assembly 1100, which is arranged at an angle to lift the material to a high place, and the material falls from the high place into the outer drum 2100 of the drum mechanism. It can be understood that the material falling from a high place increases the gravitational potential energy, and can also increase the probability and strength of collision between the material and the inner wall of the outer drum 2100 when entering, thereby promoting the separation of the shell and the pulp.

[0031] Further, the feeding mechanism 1000 includes a feeding guide cylinder 1200, Figure 1-3The feeding guide cylinder 1200 is arranged at the discharge end of the top of the feeding lifting and conveying assembly 1100, and the feeding guide cylinder 1200 is connected to the feeding end of the outer drum 2100. It can be understood that the material conveyed by the feeding lifting and conveying assembly 1100 enters the outer drum 2100 from a high place through the feeding guide cylinder 1200.

[0032] In some examples, the Figure 1-3 The feed lifting and conveying assembly 1100 includes a feed lifting and conveying belt 1101, which is arranged at an angle to achieve climbing. Further, the feed lifting and conveying assembly 1100 includes at least one feed conveying baffle 1102, which is arranged on the surface of the feed lifting and conveying belt 1101, and the feed conveying baffle 1102 extends in a direction parallel to the width of the feed lifting and conveying belt 1101. It can be understood that when the feed conveying baffle 1102 is provided as at least two, the feed conveying baffle 1102 is arranged on the surface of the feed lifting and conveying belt 1101 at intervals.

[0033] Combined with Figure 1-3 The feeding mechanism 1000 includes a feeding hopper 1300, which is arranged on the side of the feeding lifting and conveying assembly 1100, and the feeding hopper 1300 is arranged near the lower end of the feeding lifting and conveying assembly 1100. The material is put into the feeding hopper 1300, and the feeding lifting and conveying assembly 1100 conveys the material in the feeding hopper 1300 to a high place.

[0034] The other components and operations of the fruit shell separation equipment have been recorded in the relevant technology for ordinary technicians in this field and will not be described in detail here. The structure of the drum mechanism will be introduced below.

[0035] The present application relates to a roller mechanism, which includes a roller assembly 2000 and a rotating shaft assembly 3000. The material provided by the feeding mechanism 1000 enters the roller assembly 2000, and the roller assembly 2000 rotates and drives the material to fall onto the rotating shaft assembly 3000. The material collides with the rotating shaft assembly 3000, so that the pulp and the shell are separated by force.

[0036] Specifically, the drum assembly 2000 includes an outer drum 2100, which is rotatable and Figure 1-2 , Attachment Figure 2-1 and attached Figure 2-3 The outer drum 2100 is placed horizontally, the outer drum 2100 is hollow, and both ends of the outer drum 2100 are connected. Further, the drum assembly 2000 includes at least one first fan blade 2200, Figure 2-3The first blades 2200 are arranged on the inner side wall of the outer drum 2100, and the first blades 2200 extend in a direction parallel to the axial direction of the outer drum 2100. It can be understood that when at least two first blades 2200 are provided, the first blades 2200 are arranged at intervals on the inner side wall of the outer drum 2100. Furthermore, the first blades 2200 are arranged at equal intervals.

[0037] Combined with Figure 2-2 and attached Figure 2-5 The shaft assembly 3000 includes an inner main shaft 3100, which is horizontally arranged and passes through the outer drum 2100. The inner main shaft 3100 and the outer drum 2100 are arranged coaxially. Further, the shaft assembly 3000 includes at least one second fan blade 3200. Figure 2-5 , the second blade 3200 is connected to the inner main shaft 3100, and the second blade 3200 extends in a direction parallel to the axial direction of the inner main shaft 3100. It can be understood that when the second blade 3200 is provided as at least two, the second blades 3200 are arranged at equal intervals on the side of the inner main shaft 3100. Further, each second blade 3200 is arranged at equal intervals.

[0038] Combined with Figure 2-2 , the second blade 3200 is located in the outer drum 2100. It can be understood that the material enters from the feeding end of the outer drum 2100, and when the outer drum 2100 rotates, the first blade 2200 carries the material to a high place, the material falls from the first blade 2200, and the surface of the second blade 3200 collides with the material to separate the pulp and the shell.

[0039] Furthermore, the inner main shaft 3100 and the outer drum 2100 rotate relative to each other, so that the second blade 3200 hits the material falling from the first blade 2200, increasing the impact force of the second blade 3200 on the material. It should be noted that the hitting of the material by the second blade 3200 may also cause the material to fly toward the surface of the first blade 2200 or the inner side wall of the outer drum 2100, so that the material hits the first blade 2200 or the outer drum 2100, increasing the number of times the material hits, and promoting the separation of the pulp and the shell.

[0040] As an embodiment, one side of the first blade 2200 has a concave material groove 2203, and the material groove 2203 extends from one end to the other end of the first blade 2200 in a direction parallel to the axial direction of the outer drum 2100. Figure 2-2, taking the rotation direction of the outer drum 2100 as a reference, the material trough 2203 is arranged on the front side of the first blade 2200. When the outer drum 2100 rotates, the material trough 2203 of the first blade 2200 at a lower position has material. When the first blade 2200 rotates to a higher position with the outer drum 2100, the material trough 2203 is in a tilted state, and the material falls from the material trough 2203.

[0041] It is understandable that the material trough 2203 is designed on the side of the first blade 2200 to facilitate the first blade 2200 to carry more materials and prevent the materials from falling prematurely, thereby ensuring that more materials fall from a high place to the surface of the second blade 3200.

[0042] Combined with Figure 2-2 and attached Figure 2-4 , one side of the first blade 2200 has a concave arc surface to form a material groove 2203. Specifically, the side of the first blade 2200 is concave to form a material groove 2203 with a curved surface, or the first blade 2200 is bent to form an arc plate, so that the cross section of the first blade 2200 is formed in the shape of the material groove 2203.

[0043] Regarding the arrangement of the first fan blade 2200, at least the following replacement designs can be made.

[0044] In some examples, a convex strip is provided on the side of the first blade 2200, the convex strip protrudes from the side of the first blade 2200, and the convex strip extends in a direction parallel to the axial direction of the outer drum 2100. It is understandable that a material groove 2203 is formed between the convex strip on the side of the first blade 2200 and the inner wall of the outer drum 2100.

[0045] In other examples, on the inner wall of the outer drum 2100, the side of the first blade 2200 is arranged obliquely relative to the radial direction of the outer drum 2100. With reference to the rotation direction of the outer drum 2100, one side of the first blade 2200 is inclined forward so that a space for temporarily placing materials is formed between the side of the first blade 2200 and the side wall of the outer drum 2100. Furthermore, a material trough 2203 is provided on the side of the first blade 2200 to increase the amount of materials that the first blade 2200 can carry.

[0046] As an embodiment, the drum assembly 2000 includes a first baffle 2101, Figure 2-3 The first baffle 2101 is connected to the outer drum 2100 and is disposed at the feed end of the outer drum 2100. The first baffle 2101 reduces the inlet of the feed end of the outer drum 2100 to prevent the material from falling out of the feed end of the outer drum 2100. Further, the first baffle 2101 is provided with a feed port, which passes through the first baffle 2101 and is connected to the inner cavity of the outer drum 2100.

[0047] Combined with Figure 2-3 The first baffle 2101 is configured as an annular baffle, and the cavity area formed in the middle of the annular shape of the first baffle 2101 serves as a feed inlet.

[0048] As an embodiment, the drum assembly 2000 includes a feed guide plate 2201, Figure 2-4 A feed guide plate 2201 is provided on one end of the first blade 2200 close to the feed end of the outer drum 2100, and the feed guide plate 2201 is arranged obliquely relative to the side of the first blade 2200. With reference to the rotation direction of the outer drum 2100, the end of the feed guide plate 2201 away from the first blade 2200 is inclined forward. Figure 2-4 The feed guide plate 2201 is inclined toward the side where the material trough 2203 is located, so that the material at the feed end of the outer drum 2100 can enter the material trough 2203 of the first fan blade 2200 along the feed guide plate 2201.

[0049] Furthermore, the feed guide plate 2201 is close to the inner side surface of the first baffle plate 2101 so as to allow the material close to the first baffle plate 2101 to enter the material trough 2203 as much as possible.

[0050] Combined with Figure 2-4 The feed guide plate 2201 is configured as an arc-shaped plate to form an inclined guide plate. Alternatively, the feed guide plate 2201 is configured as an inclined plate.

[0051] As an embodiment, the drum assembly 2000 includes a discharge guide plate 2202, Figure 2-3 and attached Figure 2-4 The first blade 2200 is provided with a discharge guide plate 2202 at one end close to the discharge end of the outer drum 2100. The discharge guide plate 2202 is arranged obliquely relative to the side of the first blade 2200. With reference to the rotation direction of the outer drum 2100, the end of the discharge guide plate 2202 away from the first blade 2200 is inclined backward. Figure 2-4 The discharge guide plate 2202 is inclined toward the other side of the side where the material trough 2203 is located, so that the material can fall out of the outer drum 2100 through the discharge guide plate 2202 .

[0052] It should be noted that, in the case where the first blade 2200 is provided with a feed guide plate 2201, Figure 2-4 The inclination directions of the discharge guide plate 2202 and the feed guide plate 2201 are opposite.

[0053] In some examples, the drum mechanism includes a discharge guide groove 2102, and the discharge guide groove 2102 is located at the discharge end of the outer drum 2100. Figure 1-2 , Attachment Figure 2-1 and attached Figure 2-6The discharging guide groove 2102 is arranged close to the lower side of the outer drum 2100 , and the discharging guide groove 2102 is arranged obliquely, so that the fruit shells and pulp in the outer drum 2100 slide down the discharging guide groove 2102 and fall out.

[0054] Further, the roller mechanism includes a second baffle 2103, combined with the attached Figure 2-1 The second baffle 2103 is located at the discharge end of the outer drum 2100 , the second baffle 2103 is arranged close to the upper side of the outer drum 2100 , and a cavity area is reserved on the lower side of the outer drum 2100 to form a discharge port.

[0055] As an implementation method, in combination with the attached Figure 1-1 , Attachment Figure 1-2 and attached Figure 2-6 The drum mechanism includes a frame 4000, a discharge guide 2102 connected to the frame 4000, and a second baffle 2103 connected to the frame 4000. It can be understood that the discharge guide 2102 and the frame 4000 do not rotate with the outer drum 2100.

[0056] It should be noted that, when the first baffle 2101 is provided at the feed end of the outer drum 2100, the first baffle 2101 can be designed to be connected to the outer drum 2100, or the first baffle 2101 can be designed not to be connected to the outer drum 2100, but the first baffle 2101 is connected to the frame 4000, and the first baffle 2101 does not rotate with the outer drum 2100.

[0057] It is understandable that, combined with the Figure 1-1 The drum assembly 2000 is arranged on the frame 4000, the outer drum 2100 is rotatable in the frame 4000, and both ends of the inner main shaft 3100 are respectively connected to the frame 4000.

[0058] As an embodiment, the drum mechanism includes a first driving assembly, the first driving assembly is disposed on the frame 4000, and the first driving assembly is connected to the outer drum 2100 to drive the outer drum 2100 to rotate.

[0059] Specifically, in combination with Figure 1-2 The first driving assembly includes a first driver 4101, a first driving shaft 4102 and at least one driving wheel 4103. The first driver 4101 includes a motor. The first driver 4101 is disposed on the frame 4000. The first driving shaft 4102 is connected to the first driver 4101. The driving wheel 4103 is disposed on the first driving shaft 4102. The side of the driving wheel 4103 contacts the outer side wall of the outer drum 2100. It can be understood that the first driver 4101 drives the driving wheel 4103 to rotate through the first driving shaft 4102, and the side of the driving wheel 4103 rubs against the outer side wall of the outer drum 2100 to drive the outer drum 2100 to rotate.

[0060] Furthermore, combined with Figure 1-2 and attached Figure 2-6 The outer wall of the outer drum 2100 is provided with an annular groove 2104 along the circumference, and the annular groove 2104 corresponds to the position of the driving wheel 4103 to prevent the outer drum 2100 from shifting in position during rotation. The side of the driving wheel 4103 contacts the bottom of the annular groove 2104 to ensure stable transmission between the driving wheel 4103 and the outer drum 2100.

[0061] Regarding the annular groove 2104, as an alternative, it can at least be designed as follows: an annular baffle is provided on the outer side wall of the outer drum 2100, and the annular baffle is used to abut the end face of the driving wheel 4103 to prevent the position of the outer drum 2100 from being offset.

[0062] In order to ensure the smooth rotation of the outer drum 2100, at least one coaxially arranged roller 4104 is provided on the frame 4000. Figure 1-1 and attached Figure 2-6 The side of the roller 4104 contacts the outer wall of the outer drum 2100 , and the roller 4104 and the driving wheel 4103 jointly support the outer drum 2100 .

[0063] In some examples, the Figure 1-2 , two driving wheels 4103 are provided, and the two driving wheels 4103 are respectively close to the two ends of the outer drum 2100, and two rollers 4104 are provided, and the two rollers 4104 are respectively close to the two ends of the outer drum 2100. Further, the driving wheel 4103 and the roller 4104 located at the same end of the outer drum 2100 share an annular groove 2104.

[0064] As an embodiment, the inner spindle 3100 can rotate, and the inner spindle 3100 can rotate. Figure 1-2 , both ends of the inner main shaft 3100 are connected to the frame 4000 through bearing seats. It can be understood that the roller mechanism includes a second drive assembly, the second drive assembly is arranged on the frame 4000, and the second drive assembly is connected to the inner main shaft 3100 to drive the inner main shaft 3100 to rotate.

[0065] Specifically, in combination with Figure 1-2 The second driving assembly includes a second driver 4201, which includes a motor. The second driver 4201 is disposed on the frame 4000, and the rotating shaft of the second driver 4201 is connected to the inner spindle 3100 to drive the inner spindle 3100 to rotate. Alternatively, the second driver 4201 drives the inner spindle 3100 to rotate in a belt transmission or gear meshing transmission manner.

[0066] It should be noted that regarding the relative rotation between the inner main shaft 3100 and the outer drum 2100, there are at least the following situations.

[0067] In some examples, the outer drum 2100 rotates while the inner main shaft 3100 does not rotate, so as to achieve relative rotation between the inner main shaft 3100 and the outer drum 2100 .

[0068] In some other examples, the outer drum 2100 and the inner main shaft 3100 both rotate in opposite directions to achieve relative rotation between the inner main shaft 3100 and the outer drum 2100 .

[0069] In some other examples, the outer drum 2100 and the inner spindle 3100 both rotate in the same direction, the rotation speed of the inner spindle 3100 is greater than the rotation speed of the outer drum 2100, or the rotation speed of the inner spindle 3100 is less than the rotation speed of the outer drum 2100, so as to achieve relative rotation between the inner spindle 3100 and the outer drum 2100.
