Abstract
Description
Technical Field
[0001] The present application relates to the field of tea oil production equipment, and in particular to a tea oil fruit shelling device. Background Art
[0002] The tea oil tree is an annual woody oil crop. During the picking season every year, the tea oil fruits must be dried or baked in advance after picking to remove excess moisture. On the one hand, it is beneficial for storage before oil extraction, and on the other hand, it is beneficial to increase the shelling rate in the subsequent mechanical shelling stage.
[0003] The prior art provides a variety of tea oil fruit shelling equipment, such as the invention patent with application number: 202211705426.8. By designing multiple groups of screening mechanisms with different spacings, the screening rods cooperate with each other to screen the tea oil fruits, and then the screening rods can separate tea oil fruits of different sizes. Heating at different temperatures can dry tea oil fruits of different sizes respectively, so that the tea oil fruit shells are dehydrated, making subsequent shelling easier. At the same time, it can avoid uneven heating of the tea oil fruits and improve the quality of the tea oil fruits.
[0004] The invention patent with application number 202211653772.6 achieves higher shelling efficiency for tea oil fruits of different particle sizes by arranging a screening component for screening different outer diameters and multiple groups of small-pitch rollers and large-pitch rollers in the shelling box.
[0005] The above patents all focus on pre-screening and then grading the shelling of tea oil fruits. The multi-stage shelling design makes its structure not compact enough. Moreover, since the success rate of shelling of tea oil fruits with small particles is significantly lower than that of tea oil fruits with large particles, in practice, tea oil fruits with small particles often require secondary extrusion for shelling, resulting in unsatisfactory actual use results. Summary of the invention
[0006] In order to further improve the efficiency of shelling tea oil fruits and take into account the one-time shelling rate of tea oil fruits with large and small particle sizes (the shelling rate of materials discharged from the discharge port), the present application provides a tea oil fruit shelling device, including a device body, a shelling component and a conveying component. A feed hopper is provided at the feed inlet of the device body. The shelling component and the conveying component are sequentially arranged in the device body and located below the feed hopper. The shelling component includes a first roller body, a first driving member, a second roller body, a second driving member and a third roller body. The first roller body and the second roller body are arranged in parallel in the device body; the first driving member is provided on the device body, and is used to drive the first roller body to rotate around its own axis. Rotate; when the first roller body rotates, the second roller body rotates synchronously, and the rotation direction of the second roller body is opposite to that of the first roller body; a first extrusion and shell breaking area is formed between the first roller body and the second roller body; a cavity is arranged inside the second roller body, and a feeding port connected with the internal cavity is opened on the second roller body; the third roller body is arranged inside the second roller body, and the second driving member is installed outside the device body to drive the third roller body to rotate around its own axis, and a second extrusion and shell breaking area is formed between the outer wall of the third roller body and the inner wall of the second roller body, and a guide plate is arranged on the feed hopper, the guide plate abuts against the second roller body, and a holding space for holding tea oil fruit is formed between the guide plate and the second roller body.
[0007] Preferably, a driving gear is provided at one end of the first roller body away from the first driving member, and a driven tooth capable of meshing with the driving gear is provided at the end of the second roller body. The rotation direction of the third roller body is the same as that of the second roller body, and the rotation speed can have a certain linear speed difference, so that the tea oil fruit can be simulated by kneading and shelling in the second extrusion shell breaking area.
[0008] Preferably, a conveying assembly is provided below the first roller body and the second roller body, and the conveying assembly includes a first conveying line and a second conveying line. The first conveying line is located below the first extrusion and shell breaking zone and is used to deliver the shelled tea oil fruits that fall from the first extrusion and shell breaking zone out of the device body; the second conveying line is located below the second extrusion and shell breaking zone and is used to deliver the shelled tea oil fruits that fall from the second extrusion and shell breaking zone out.
[0009] Preferably, a partition is fixedly arranged inside the device body, and the partition separates the falling materials in the first extrusion and shell breaking zone from the falling materials in the second extrusion and shell breaking zone, and guides them to the first conveying line and the second conveying line respectively.
[0010] Preferably, a vibrating screen plate is provided in the device body, and the vibrating screen plate includes a first screening part, a second screening part, a rotating shaft and a cam. The rotating shaft is fixedly arranged in the device body and is located above the isolation plate and the first conveying line and the second conveying line. The connection between the first screening part and the second screening part is hinged on the rotating shaft, and the rotation of the cam drives the first screening part and the second screening part to vibrate respectively.
[0011] Preferably, a guide plate is provided in the device body, and the guide plate guides the falling materials passing through the first extrusion shell breaking zone or the second extrusion shell breaking zone to fall in front of the vibrating screen plate to ensure sufficient screening time.
[0012] In summary, compared with the prior art, the present application has the following beneficial effects:
[0013] The present application has a compact structure and can achieve the separation of large and small particle size tea oil fruit shells (the large and small particle sizes here refer to the fruit diameter of tea oil fruits larger than a certain specific particle size and the fruit diameter of tea oil fruits smaller than a certain specific particle size). In particular, the present application pays attention to the fact that the shelling rate of small-particle tea oil fruits is often not high after one-time extrusion and shelling. Therefore, the second extrusion shelling area that can be repeatedly extruded and shelled is designed to specifically process small-particle tea oil fruits, thereby improving the success rate of shelling of small-particle tea oil fruits.
[0014] In addition, in order to improve the shelling rate of small-sized particles, the rotation speeds of the second roller and the third roller are designed to have a certain speed difference, thereby achieving rubbing and squeezing shelling of small-sized tea oil fruits and improving the one-time shelling rate.

DETAILED DESCRIPTION
[0028] Embodiment 1
[0029] Reference Figure 1-Figure 6 as well as Fig.11 and Fig.12The entire device includes a frame 601, a device body 1 and a shelling assembly 2, wherein the device body 1 is installed on the frame 601, a feed hopper 101 is provided at the feed inlet of the device body 1, the shelling assembly 2 is arranged in the device body 1 and below the feed hopper 101, and a guide plate 1011 that can be tangent to the outer wall of the second roller body 204 extends from the feed hopper 101, so that a containing space 5 is formed between the guide plate 1011 and the second roller body 204, so that the tea oil fruit put through the feed hopper 101 can be accumulated in the containing space 5. The shelling assembly 2 includes a first roller body 201, a first driving member 202, a second driving member 203, a second roller body 204 and a third roller body 205 arranged in the second roller body 204; the first roller body 201 is arranged in the device body 1 and can rotate around its own axis, the first driving member 202 is a driving motor, the first driving member 202 drives the first roller body 201 to rotate, and the other end of the first roller body 201 relative to the first driving member 202 is provided with a driving gear 2011; the second roller body 204 is parallel to the first roller body 201, and a first extrusion shell breaking area 3 for shelling tea oil fruits with larger particle size is formed between the second roller body 204 and the first roller body 201; the third roller body 205 is arranged in the second roller body 204, the axis of the third roller body 205 and the second roller body 204 are not coaxial, and a second extrusion shell breaking area 4 is formed between the inner wall of the coaxial second roller body 204 and the third roller body 205.
[0030] The second driving member 203 is arranged at a position on the device body 1 corresponding to the second roller body 204. The second driving member 203 is a driving motor. The output shaft of the second driving member 203 passes through the device body 1 and the end cover 103 and is connected to the third roller body 205. The second driving member 203 is used to drive the third roller body 205 to rotate around its own axis in the second roller body 204. The rotation direction of the third roller body 205 is the same as that of the second roller body 204, and the rotation speed is faster than the rotation speed of the second roller body 204.
[0031] One end of the second roller body 204 is not closed and is connected to a driven gear 2041. The end face of the driven gear 2041 maintains a certain distance from the end face of the second roller body, and a discharge port 20421 is reserved; the other end of the second roller body 204 is provided with an end cover 103, and the end cover 103 is connected to the end of the second roller body 204 by plug-in fitting. After the driving gear 2011 rotates, the second roller body 204 can rotate around its own axis driven by the driven gear 2041, and its rotation direction is opposite to that of the first roller body 201, so that the second roller body 204 and the first roller body 201 can shell the tea oil fruit entering the first extrusion shell breaking area 3.
[0032] A feeding port 20431 is provided on the outer circumference of the second roller body 204. When the tea oil fruits enter the containing space 5 through the feeding hopper 101, the tea oil fruits with large particles cannot pass through the feeding port 20431 to enter the second extrusion and shell breaking area 4 due to the rotation of the second roller body, and are thus transferred to the first extrusion and shell breaking area 3 along with the second roller body 204 for extrusion and shelling; while the tea oil fruits with slightly smaller particles directly fall into the second extrusion and shell breaking area 4 through the feeding port 20431, and are kneaded, extruded and shelled between the third roller body 205 and the inner wall of the second roller body 204.
[0033] Reference Figure 1 , Figure 2 and Figure 3 , a conveying assembly 6 is also arranged below the device body 1, and the conveying assembly 6 includes a first conveying line 602, a second conveying line 603 and a shaking screen mechanism 604 arranged between the first conveying line 602 and the second conveying line 603, wherein the shaking screen mechanism 604 includes a connecting shaft 6041, two vibrating screen plates 6042, two third driving members 6043 and two cam shafts 6044, a frame 601 is arranged between the first conveying line 602 and the second conveying line 603, the frame 601 is located below the device body 1 and is fixedly connected to the device body 1, and the connecting shaft 6041 is fixedly arranged in the device body 1, the axis of the connecting shaft 6041 is parallel to the axis of the first roller body 201, the two vibrating screen plates 6042 are hinged on the connecting shaft 6041 and can be turned up and down relative to the connecting shaft 6041, one end of the vibrating screen plate 6042 away from the connecting shaft 6041 is located on the first conveying line 602, and one of them The third driving member 6043 and the camshaft 6044 are arranged at one end of the first conveyor line 602 close to the frame 601, and the camshaft 6044 abuts against one end of the vibrating screen plate 6042 away from the connecting shaft 6041. The third driving member 6043 is a driving motor, and the output shaft of the third driving member 6043 is connected to the camshaft 6044 arranged on the first conveyor line 602, so that when the camshaft 6044 on the first conveyor line 602 starts to rotate, the vibrating screen plate 6042 located above the first conveyor line 602 starts to flip up and down relative to the connecting shaft 6041, so that the fruit shells and fruits that fall out of the first extrusion shell breaking area 3 from the impact plate 108 can be screened through the vibrating screen plate 6042, wherein the fruit shells fall on the first conveyor line 602 and are sent away, while the fruits fall after passing through the vibrating screen plate 6042, and correspondingly, a collection box 7 for collecting fruits is arranged below the vibrating screen plate 6042.
[0034] The end of the other vibrating screen plate 6042 away from the connecting shaft 6041 is located on the second conveying line 603, and another third driving member 6043 and another cam shaft 6044 are both installed on the end of the second conveying line 603 close to the frame 601. The cam shaft 6044 can abut against the vibrating screen plate 6042 above the second conveying line 603, so that when the third driving member 6043 on the second conveying line 603 is started, the vibrating screen plate 6042 above the second conveying line 603 is also connected relatively. The shaft 6041 is flipped up and down, so that the fruit shells and fruits discharged from the discharge port 20421 on the discharge side 2042 can be separated from the fruit shells when they fall on the vibrating screen plate 6042 as the vibrating screen plate 6042 is flipped up and down, and the fruit shells on the vibrating screen plate 6042 fall on the second conveyor line 603 and are sent away, while the fruits fall after passing through the vibrating screen plate 6042. Correspondingly, another collection box 7 for collecting fruits is also provided below the vibrating screen plate 6042.
[0035] It is worth mentioning that the mesh diameter of the vibrating screen plate 6042 located on the second conveying line 603 needs to be smaller than the mesh diameter of the vibrating screen plate 6042 located on the first conveying line 602 .
[0036] Embodiment 2
[0037] The key difference between the second embodiment and the first embodiment lies in the design of the feeding and discharging structure of the second roller. Figure 7 , Figure 8 , Fig. 9 and Fig.10 The second roller body 204 is provided with a feed inlet 20431 and a discharge outlet 20421 of different shapes along the central axis. The second roller body 204 is close to the second drive motor as the feed side 2043, and close to the driven gear 2041 as the discharge side 2042. The feed hopper 101 corresponds to the position of the feed side 2043 on the second roller body 204; the feed side 2043 and the discharge side 2042 are provided with cavities that are interconnected, and the second roller body 204 is in the feed side. A feed port 20431 extending in a direction parallel to the axis of the second roller body 204 is provided on the side 2043, and the feed port 20431 is connected to the cavity in the feed side 2043; and a plurality of discharge ports 20421 connected to the cavity at the discharge side 2042 are provided at the discharge side 2042, and the extension direction of the discharge port 20421 is parallel to the axis of the second roller body 204, and the plurality of discharge ports 20421 are distributed circumferentially at the discharge side 2042.
[0038] As the second roller body 204 rotates, the tea oil fruits that cannot enter the second extrusion shell breaking area 4 through the feed port 20431 are driven to the first extrusion shell breaking area 3 for shell breaking, while the tea oil fruits that can pass through the feed port 20431 have a smaller particle size and enter the second extrusion shell breaking area 4 for shell breaking. The first isolation plate 111 prevents the tea oil fruits in the holding space 5 from entering the second extrusion shell breaking area 4 through the discharge port 20421 at the discharge side 2042 without shell breaking.
[0039] Embodiment 3
[0040] In order to improve the efficiency of falling materials after extrusion and shelling in the second extrusion shell breaking area 4, the device is also connected to a blowing pipe 102, one end of which is located in the feed side 2043, and is used to blow the tea oil fruit that has been shelled at the feed side 2043 toward the discharge side 2042, so that the tea oil fruit that has been shelled can collide in the cavity at the discharge side 2042 driven by the airflow, thereby realizing the separation of the shell and the fruit, and falling out from the discharge port 20421 (or at the end of the second roller body 204) as the discharge side 2042 rotates.
[0041] It is worth mentioning that the outer wall of the second roller body 204 is knurled during processing, and the outer wall has a knurled pattern not shown in the figure, which increases the friction between the outer wall of the second roller body 204 and the tea oil fruit in the holding space 5, thereby reducing the probability that the tea oil fruit cannot be driven by the second roller body 204 to move toward the first extrusion and shell breaking area 3 and accumulate in the holding space 5.
[0042] Reference Fig. 9 and Fig.10 It should be noted that, since the end of the third roller body 205 away from the second driving member 203 is in a suspended state at the feed side 2043, a support ring 104 is also provided on the end cover 103, and the end of the support ring 104 is vertically fixed to the end cover 103, and the other end of the support ring 104 is plugged into the end of the third roller body 205 close to the end cover 103, which makes the output shaft of the second driving member 203 do not need to bear the gravity load from the third roller body 205, thereby reducing the probability of bending deformation of the output shaft of the second driving member 203 without affecting the rotation of the third roller body 205.
[0043] Reference Fig. 9 , Fig.10At the position of the feeding port 20431 corresponding to the inner wall of the feeding side 2043, an arc-shaped baffle 20432 matching the shape of the feeding port 20431 of the second roller body 204 is hinged, one end of the arc-shaped baffle 20432 is a hinged end, and the other end of the arc-shaped baffle 20432 is a free end. When the feeding port 20431 rotates from below the guide plate 1011 to above the guide plate 1011, the free end of the arc-shaped baffle 20432 is hinged under the action of its own gravity. The feed port 20431 is opened, so that the tea oil fruits in the holding space 5 can be screened through the feed port 20431 on the feed side 2043; and as the second roller body 204 rotates, when the feed port 20431 rotates toward the first roller body 201, the arc-shaped baffle 20432 will rotate relative to the feed port 20431 under the action of its own weight until the feed port 20431 is sealed. This design can prevent the tea oil fruits from being thrown out in the second extrusion and shell breaking area 4.
[0044] A separation wedge 105 is also fixedly provided on the end cover 103. The separation wedge 105 fits closely to the outer wall of the second roller body 204 as much as possible without affecting the rotation of the second roller body 204. If there is a tea oil fruit stuck at the feed inlet 20431, when it rotates with the second roller body 204 to the position of the separation wedge 105, the separation wedge 105 can pick out the tea oil fruit stuck at the feed inlet 20431 and enter the first extrusion shell breaking area 3 for shell breaking, thereby avoiding the situation where the tea oil fruit is stuck at the feed inlet 20431 and causes subsequent feeding difficulties.
[0045] Furthermore, the separation wedge 105 is made of a magnetic material, and the arc baffle 20432 is also made of a ferromagnetic material. This allows the arc baffle 20432 to seal the feed port 20431 in advance due to the mutual attraction between the arc baffle 20432 and the separation wedge 105. This is more reliable than simply sealing the feed port 20431 by the gravity of the arc baffle 20432.
[0046] In order to prevent the tea oil fruit in the first extrusion and shell breaking zone 3 from getting stuck in the feed port 20431 of the second roller body 204, an arc-shaped limiting plate 106 is further provided on the end cover 103, and a protrusion adapted to the feed port 20431 is provided on the arc-shaped baffle 20432, and when the arc-shaped baffle 20432 seals the feed port 20431, the protrusion on the arc-shaped baffle 20432 fills the feed port 20431. At this time, the position of the protrusion away from the arc-shaped baffle 20432 can be flush with the outside of the feed side 2043 on the second roller body 204, and the length of the arc-shaped limiting plate 106 is the same as the length of the feed port 20431. The arc-shaped limiting plate 106 is located close to the first extrusion and shell breaking zone 3 on the feed side 2043, which makes it possible for the feed port 20431 on the feed side 2043 to rotate to the first extrusion and shell breaking zone 3, the arc baffle 20432 smoothly enters the position between the arc limit plate 106 and the inner wall of the feed side 2043 under the adsorption of the separation wedge 105 and blocks the feed inlet 20431 at the same time, and the arc limit plate 106 limits the rotation of the arc baffle 20432, so that the arc baffle 20432 can always maintain the blocking state of the feed inlet 20431 when it is in this position, and also when the tea oil fruit is shelled in the first extrusion shell breaking area 3, if the tea oil fruit happens to be aligned with the feed inlet 20431, it will not be stuck in the feed inlet 20431 due to being squeezed by the first roller body 201, and at the same time, the tea oil fruit will not be pushed into the second extrusion shell breaking area 4 under the squeezing of the first roller body 201, thereby reducing the probability of mixing.
[0047] In addition, it should be noted that since most of the tea oil fruits entering the second extrusion shell breaking area 4 through the containing space 5 will be accumulated in the second extrusion shell breaking area 4 which is far away from the first extrusion shell breaking area 3 in the horizontal direction, Figure 7 A plurality of circumferentially arranged toggle plates 2052 are provided on the outer wall of the third roller body 205, and the toggle plates 2052 are parallel to the length direction of the third roller body 205. A plurality of springs 2051 are arranged at intervals along the length direction of the toggle plates 2052 at positions corresponding to each toggle plate 2052 in the third roller body 205, so that the toggle plates 2052 can be extended and retracted on the third roller body 205, so that the tea oil fruit entering the second extrusion and shell breaking zone 4 away from the first extrusion and shell breaking zone 3 from the feed inlet can be toggled by the toggle plates 2052 to rotate in the second extrusion and shell breaking zone 4 toward the first extrusion and shell breaking zone 3, thereby performing shell breaking processing in the first extrusion and shell breaking zone 3.
[0048] It is worth mentioning that when the feed inlet 20431 rotates to the bottom of the third roller body 205, the arc baffle 20432 has already blocked the feed inlet 20431 when passing through the arc limit plate 106. Therefore, even if the feed inlet 20431 rotates with the feed side 2043 to the bottom of the third roller body 205, the arc baffle 20432 still blocks the feed inlet 20431 due to the gravity of the arc baffle 20432. Therefore, the toggle plate 2052 under the third roller body 205 will abut against the arc baffle 20432. At this time, the spring 2051 corresponding to the toggle plate 2052 is in a compressed state, which makes the toggle plate 2052 inserted into the feed port 20431, so that the interference between the third roller body 205 and the feed side 2043 will not easily occur, thereby achieving the effect of increasing the operating stability between the third roller body 205 and the feed side 2043.
[0049] Furthermore, the end of the toggle plate 2052 away from the spring 2051 can be made of magnetic material, so that when the feed port 20431 rotates from under the third roller body 205 toward the direction of the guide plate 1011, the arc-shaped baffle 20432 can be adsorbed by the toggle plate 2052 close to it, so that the feed port 20431 is in an open state, thereby allowing the tea oil fruit in the holding space 5 to smoothly enter the feed side 2043.
[0050] A partition 107 is fixedly installed in the device body 1, and the partition 107 is located below the first roller body 201. The partition 107 is used to separate the tea oil fruits that have been shelled in the first extrusion shell breaking area 3 and the tea oil fruits that have been shelled discharged from the discharging side 2042. This prevents the two different sizes of tea oil fruits from being easily mixed together after the shelling process, thereby facilitating the subsequent staff to sort and grade the shelled tea oil fruits.
[0051] Impact plates 108 are respectively arranged under the partition 107, wherein both ends of the impact plates 108 in the length direction are fixedly connected to the inner walls on both sides of the device body 1, and the impact plates 108 are located below the first extrusion shell-breaking area 3, which enables the tea oil fruit passing through the first extrusion shell-breaking area 3 to fall on the impact plates 108, and the separation of the shell and the fruit is achieved by impact. Furthermore, a blowing channel 109 and an air inlet pipe 110 connected to the blowing channel 109 can be arranged on the top of the device body 1, and the blowing channel 109 is located above the first extrusion shell-breaking area 3, which enables the airflow after the air inlet pipe 110 is input into the blowing channel 109 to be blown out of the blowing channel 109, so that the tea oil fruit can fall on the impact plate 108 at a faster speed after the shell is broken, thereby making its impact force greater and reducing the occurrence of incomplete peeling between the shell and the fruit.
[0052] The working principle of this embodiment is as follows: tea oil fruits are poured in through the feed hopper 101, and then the first driving member 202, the second driving member 203 and the two third driving members 6043 are started synchronously, and at this time, the air blowing pipe 102 blows air into the second extrusion shell breaking area 4, and the air flow is blown out from the feed side 2043 to the discharge side 2042; the first roller body 201, the second roller body 204, the third roller body 205 and the cam shaft 6044 start to rotate under the drive of the first driving member 202, the second driving member 203 and the third driving member 6043 respectively, and as the second roller body 204 rotates, the tea oil fruits in the holding space 5 will be driven by the second roller body 204 to move toward the first extrusion shell breaking area 3 for shell breaking, while the tea oil fruits with smaller particle sizes will enter the second extrusion shell breaking area 4 in the feed side 2043 through the feed inlet 20431 for shell breaking;
[0053] When the tea oil fruit is shelled in the first extrusion shell-breaking area 3, it will fall out of the first extrusion shell-breaking area 3, and then fall on the impact plate 108, and the separation of the shell and the fruit is achieved by impact. Subsequently, it will fall on the vibrating screen plate on the first conveyor line 602 through the impact plate 108, and the separation of the shell and the fruit will be achieved by screening the shell and the fruit; after the separation of the shell and the fruit is completed, the shell falls on the first conveyor line 602 through the vibrating screen plate 6042 on the first conveyor line 602 and is sent away, while the fruit falls into the collection box 7 located below the vibrating screen plate 6042.
[0054] When the tea-oil fruit is in the second extrusion shell-breaking zone 4, after being moved by the toggle plate 2052, it will be transferred from the second extrusion shell-breaking zone 4 away from the first extrusion shell-breaking zone 3 to the second extrusion shell-breaking zone 4 close to the first extrusion shell-breaking zone 3, and the shell will be broken between the outer wall of the third roller body 205 and the inner wall of the feeding side 2043 of the second roller body 204. The tea-oil fruit after the shell-breaking process will be blown by the airflow blown by the air pipe 102 to the tea-oil fruit at the feeding side 2043. It is blown toward the discharge side 2042, and after impacting inside the discharge side 2042, the shells and the fruits are separated. Subsequently, as the second roller body 204 rotates, the shells are discharged from the discharge port 20421 at the bottom of the discharge side 2042 and can fall onto the vibrating screen plate 6042 above the second conveyor line 603. After being shaken and screened, the shells fall onto the second conveyor line 603 and are sent away, while the fruits fall into another collection box 7 below the vibrating screen plate 6042.
[0055] Of course, in order to ensure the shelling rate of tea oil fruits with small particle sizes, during the actual shelling operation, the opening and closing of the air pipe 102 can be set to be periodic, ensuring that the tea oil fruits with small particle sizes are rubbed and squeezed enough times and the shell and seeds are separated before the blowing operation is turned on. This is also mentioned earlier that the shelling rate of large-diameter tea oil fruits is often ideal, and the shelling rate of small-diameter tea oil seeds is relatively low. In order to ensure the shelling rate, it is necessary to distinguish between large and small tea oil fruits with different particle sizes and perform shelling operations on them to different degrees.
