[0033] Please see attached Figure 1-2 In one embodiment of the present invention, an automatic sorting structure for camellia oleifera fruits is provided, comprising a mounting frame (not shown) and a sorting mechanism mounted on the mounting frame. First of all, it should be noted that the mounting frame is used for the installation of the sorting mechanism. This is different from the general screening method, which is usually performed by manual visual screening. However, since the number of camellia oleifera fruits is generally large, manual screening is labor-intensive, time-consuming and labor-intensive. Existing screening mechanisms are all screened in the same channel by setting up holes of different particle sizes. If the number of camellia oleifera fruits is large, the screening holes are easily blocked, and vibration is required to continue screening. Such a screening process is relatively cumbersome, inefficient and complex in structure. The present application solves the above-mentioned defects in the prior art by providing an automatic sorting structure for camellia oleifera fruits.

[0034] The details are as follows:

[0035] The sorting mechanism is used for screening the fruit diameter of oil-tea camellia fruits, and includes a conveying platform 10, a stopping mechanism 20 and a driving mechanism 30. The stopping mechanism 20 is in transmission connection with the driving mechanism 30. Among them, the conveying platform 10 includes a high-position end 110 and a low-position end 120 which are oppositely arranged along its own extending direction. The conveying platform 10 is inclinedly arranged on the installation frame. A plurality of long holes 130 are formed in the conveying platform 10 and are arranged at a preset interval distance along the width direction of the conveying platform 10. Each long hole 130 extends along the inclined direction of the conveying platform 10.

[0036] Specifically, the sorting mechanism includes a conveying platform 10, a stopping mechanism 20 and a driving mechanism 30. The conveying platform 10 is used as a conveying channel for oil-tea camellia fruits. To enable the oil-tea camellia fruits to slide smoothly along the conveying platform 10, the conveying platform 10 is inclinedly arranged on the installation frame. It includes a high-position end 110 and a low-position end 120 which are oppositely arranged along its own extending direction. The low-position end 120 is inclined downward from the high-position end 110. The conveying platform 10 is also used for installing the stopping mechanism 20. To enable the stopping mechanism 20 to penetrate the conveying platform 10 to stop the oil-tea camellia fruits with a large fruit diameter, a plurality of long holes 130 extending along the inclined direction of the conveying platform 10 are formed in the conveying platform 10. The plurality of long holes 130 are arranged at a preset interval distance along the width direction of the conveying platform 10. It is worth mentioning that the preset interval distance here refers to the fruit diameter limit value of the large oil-tea camellia fruits to be sorted. The oil-tea camellia fruits larger than the preset interval distance will be stopped by the arranged stopping mechanism 20, and then the driving mechanism 30 will push the stopped oil-tea camellia fruits towards the high-position end 110. Among them, the number of the long holes 130 can be set to four to form three spaced channels for the oil-tea camellia fruits to slide or be stopped, or can also be set to other numbers. The specific value can be set by those skilled in the art according to actual needs.

[0037] The stopping mechanism 20 is used for stopping the oil-tea camellia fruits with a fruit diameter larger than the preset interval distance, and includes a transmission belt 210 and multiple groups of stopping members 220 corresponding to the long holes 130 one by one. Each group of stopping members 220 includes a plurality of stopping members 220 arranged at intervals along the extending direction of the transmission belt 210. The transmission belt 210 is in transmission connection with the driving mechanism 30. Among them, the driving mechanism 30 drives the stopping mechanism 20 to move along the extending direction of the long holes 130 to push the oil-tea camellia fruits larger than the preset interval distance towards the high-position end 110.

[0038] In detail, the stop mechanism 20 is used to stop the oil tea fruit whose diameter is greater than the preset spacing distance, and includes a transmission belt 210 and a plurality of groups of stop members 220 (not shown in the figure). The transmission belt 210 is used for installing the stop members 220, and the drive mechanism 30 drives the stop members 220 to move toward the high end 110. The plurality of groups of the stop members 220 correspond to the elongated holes 130 one by one, and the one-to-one correspondence here refers to the number of the stop members 220 and the number of the elongated holes 130. The number of 130 is consistent, and each of the long holes 130 is provided with the stop member 220 group, and two adjacent stop member 220 groups work together to stop the oil-tea fruit that is greater than the preset spacing distance; wherein each of the stop member 220 groups includes a plurality of stop members 220 arranged at intervals along the extension direction of the transmission belt 210, so that the oil-tea fruit can enter the gap between the stop members 220 after falling into the stop mechanism 20, and then be stopped by two adjacent stop member 220 groups.

[0039] Furthermore, after being stopped, in order to sort the stopped tea fruit toward the high end 110, the transmission belt 210 is connected to the driving mechanism 30 so that the driving mechanism 30 rotates and drives the transmission belt 210 to rotate toward the high end 110. At the same time, the stopper 220 arranged on the transmission belt 210 pushes toward the high end 110, and the stopped tea fruit is pushed toward the high end 110 by the stopper 220, thereby completing the sorting of different fruit diameters at both ends.

[0040] It is worth mentioning that in order to prevent the stopper 220 from being blocked when it is transmitted upward from the bottom of the transmission belt 210 through the long hole 130, the gap distance between the long hole 130 and the transmission belt 210 along the length direction must be greater than the length of the stopper 220, so that the stopper 220 can pass smoothly and move to the top of the transmission belt 210 when passing through the long hole 130 from the bottom of the transmission belt 210 upward.

[0041] As a preferred embodiment of the present invention, the stopper 220 is a stopper plate, the stopper plate is in the shape of a long strip, the stopper plate is extended vertically, and the height of the stopper plate is greater than the radius of the oil-tea fruit. It should be noted that the stopper 220 is a stopper plate and is extended vertically. Its long strip shape can be more convenient for stopping the oil-tea fruit. It can also be in the shape of a round tube, a block, etc. Considering that the long strip shape occupies less space and has a better stopping effect, preferably, the stopper plate is in the shape of a long strip, and those skilled in the art can also choose according to actual needs.

[0042] Among them, if the height of the stop baffle is small, when the oil-tea fruits fall, due to the insufficient height of the stop baffle, the oil-tea fruits with a large fruit diameter will directly slide from above the stop baffle towards the low end 120. Therefore, the height of the stop baffle needs to be greater than the radius of the oil-tea fruit, and its height can be set to 12 mm to 15 mm. Those skilled in the art can set the specific value according to the actual fruit diameter of the oil-tea fruit.

[0043] As a preferred embodiment of the present invention, the conveying platform 10 includes a conveying plate 140 and two limiting plates 150 for preventing the oil-tea fruits from falling. The two limiting plates 150 are relatively fixed on both sides of the conveying platform 10 along the width direction of the conveying plate 140. It should be noted that the conveying platform 10 includes a conveying plate 140 and two limiting plates 150 for preventing the oil-tea fruits from falling. The conveying plate 140 is used for the oil-tea fruits to slide and for installing the stop mechanism 20, and the limiting plates 150 are used for preventing the oil-tea fruits from falling from both sides of the conveying plate 140. Therefore, the two limiting plates 150 are relatively fixed on both sides of the conveying platform 10 along the width direction of the conveying plate 140, and they can be connected by means of bolt connection, welding or integral molding.

[0044] As a preferred embodiment of the present invention, the driving mechanism 30 includes two driving units. Each driving unit includes two driving members 310 oppositely arranged on both sides of the rolling shaft of the conveyor belt 210. Among them, each driving member 310 includes a fixing plate 311 and a driving motor 312. The fixing plate 311 is fixed on the side wall of the limiting plate 150. A connection hole is provided on the fixing plate 311, and the driving end of the driving motor 312 is in transmission connection with the rolling shaft of the conveyor belt 210 through the connection hole.

[0045] It is worth noting that the driving mechanism 30 includes two driving units. Each driving unit needs to be correspondingly arranged with the rolling shaft of the conveyor belt 210 to drive the rolling shaft of the conveyor belt 210 to rotate, so as to drive the conveyor belt 210 to rotate. Therefore, each driving unit includes two driving members 310 oppositely arranged on both sides of the rolling shaft of the conveyor belt 210. Among them, each driving member 310 includes a fixing plate 311 and a driving motor 312. The fixing plate 311 is used for installing the driving motor 312, and it can be bolted to the side wall of the limiting plate 150. In order to connect the driving end of the driving motor 312 with the rolling shaft of the conveyor belt 210, a connection hole (not shown in the figure) is provided on the fixing plate 311, so that the driving end of the driving motor 312 is in transmission connection with the rolling shaft of the conveyor belt 210 through the connection hole.

[0046] Furthermore, the preset spacing distance is 26 mm to 30 mm. It is worth mentioning that the setting of the preset spacing distance is determined according to the target limit value of the oil-tea fruits to be sorted. The size of the oil-tea fruit diameter to be distinguished is the reference value of the spacing distance. Therefore, the preset spacing distance can be set to 26 mm to 30 mm, and the specific value can be selected by those skilled in the art according to needs.

[0047] As a preferred embodiment of the present invention, it further includes a protective cover 40 provided with an opening. The protective cover 40 is disposed above the high-position end 110 and fixedly connected to the limiting plate 150. It should be noted that the protective cover 40 serves as the entrance for the oil-tea fruits. The oil-tea fruits to be sorted can enter through the protective cover 40 and then fall into the sorting mechanism. To prevent the oil-tea fruits from directly falling from the low-position end 120 before being sorted, the protective cover 40 is disposed above the high-position end 110, so that the oil-tea fruits to be sorted enter through the protective cover 40 and then fall from the high-position end 110. The oil-tea fruits smaller than the preset spacing distance slide towards the low-position end 120, and the oil-tea fruits larger than the preset spacing distance are blocked by the blocking mechanism 20 and pushed towards the high-position end 110.

[0048] As a relatively preferred embodiment of the present invention, it further includes a transport table 50 for transporting the oil-tea fruits larger than the preset spacing distance. The transport table 50 is correspondingly arranged with the conveying material table 10. The transport table 50 includes a first end and a second end oppositely arranged along its own extending direction. The first end is fixedly connected to the high-position end 110, and the second end is inclined downward from the first end.

[0049] It is worth explaining that the transport table 50 is used to transport the oil-tea fruits larger than the preset spacing distance as the conveying channel after sorting. To ensure that the oil-tea fruits can smoothly enter the transport table 50 after sorting, the transport table 50 is correspondingly arranged with the conveying material table 10. Here, the corresponding arrangement means that its width is the same as that of the conveying material table 10, and limiting plates 150 for preventing the oil-tea fruits from falling are also provided on both sides; the transport table 50 includes a first end (not marked in the figure) and a second end (not marked in the figure) oppositely arranged along its own extending direction. The first end is used to connect with the high-position end 110 of the conveying material table 10, and the second end is inclined downward from the first end so that the oil-tea fruits larger than the preset spacing distance can fall by themselves along the inclined direction of the transport table 50.

[0050] Further, the spacing distance between two adjacent said stop baffles along the movement direction of the conveyor belt 210 is 50 mm to 70 mm. It should be noted that if the spacing distance between two adjacent said stop baffles along the movement direction of the conveyor belt 210 is too small, the oil-tea fruits falling from above into the stop mechanism 20 cannot fall into the gap, and thus cannot be stopped by the stop baffles. Therefore, the spacing distance is set to 50 mm to 70 mm, which is set according to the usual size of oil-tea fruits, and those skilled in the art can select according to actual needs.

[0051] Further, the protective cover 40 is fixedly connected to the limit plate 150 by bolts. It is easy to understand that connecting by bolts facilitates installation and disassembly, so as to adjust the position of the protective cover 40.

[0052] Further, the inclination angle of the conveying platform 10 is 15° to 20°. It can be understood that the inclination angle of the conveying platform 10 should not be too large. If the angle is too large, larger oil-tea fruits will directly fall to the low end 120, resulting in sorting errors. Therefore, the inclination angle of the conveying platform 10 can be set to 15° to 20°, and the specific value can be set by those skilled in the art according to the actual situation.

[0053] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
