Description

Technical Field

[0001] This invention relates to the field of fruit sorting technology, and more specifically, to a small fruit rejection machine. Background Technology

[0002] As the economy develops and people's incomes rise, their pursuit of a higher standard of living also increases. By screening fruits of different economic values, users can accurately purchase the different grades of fruit they need. However, the technology for screening fruits smaller than the average size is still relatively rudimentary and outdated, and the performance of equipment for removing small fruits needs continuous improvement.

[0003] Currently, the commonly used method for removing small fruits in my country is still simple mechanical sieving, such as passing fruits through a conveyor belt with holes of varying diameters to separate them by size. This method has low sorting efficiency and inaccurate sorting precision. Summary of the Invention

[0004] The object of the present invention includes, for example, providing a small fruit removal machine that can perform small fruit removal operations with high efficiency.

[0005] The embodiments of the present invention can be implemented as follows:

[0006] An embodiment of the present invention provides a small fruit removal machine, which includes a shaft assembly bracket, a first support shaft assembly, a second support shaft assembly, a first drive mechanism, and a second drive mechanism. Both the first drive mechanism and the second drive mechanism are mounted on the shaft assembly bracket. The first support shaft assembly includes a plurality of first support shafts, and the second support shaft assembly includes a plurality of second support shafts. The plurality of first support shafts and the plurality of second support shafts are alternately arranged on the shaft assembly bracket, with gaps between the first support shafts and the second support shafts. The first drive mechanism is drively connected to the plurality of first support shafts to drive the plurality of first support shafts to rotate. The second drive mechanism is drively connected to the plurality of second support shafts to drive the plurality of second support shafts to rotate. The rotation direction of the plurality of first support shafts is opposite to the rotation direction of the plurality of second support shafts.

[0007] During the process of removing small fruits, as the fruit passes through the gap between the first and second support shafts, the small fruits fall through the gap between the first and second support shafts. The first drive mechanism drives multiple first support shafts to rotate around their own central axis, and the second drive mechanism drives multiple second support shafts to rotate around their own central axis. The first and second support shafts rotate in opposite directions, and the large fruits move along the inclined direction of the first support shaft between the first and second support shafts. In this process, small and large fruits are sorted, achieving the effect of removing small fruits.

[0008] Optionally, both the first and second drive mechanisms include a motor, a chain, and a sprocket assembly. A first support shaft sprocket is provided on each of the plurality of first support shafts, and a second support shaft sprocket is provided on each of the plurality of second support shafts. The motor is connected to the sprocket assembly for transmission, and the chain cooperates with the sprocket assembly. The plurality of first support shaft sprockets are arranged along the same straight line, and the plurality of second support shaft sprockets are arranged along the same straight line. The plurality of first support shaft sprockets cooperate with the chain in the first drive mechanism, and the plurality of second support shaft sprockets cooperate with the chain in the second drive mechanism.

[0009] One set of motors, chains, and sprockets drives multiple first support shaft sprockets to rotate, thereby causing multiple first support shafts to rotate synchronously. Another set of motors, chains, and sprockets drives multiple second support shaft sprockets to rotate, thereby causing multiple second support shafts to rotate synchronously, thus facilitating the transport of large fruits.

[0010] Optionally, the small fruit removal machine further includes a first spacing adjustment mechanism and a second spacing adjustment mechanism. Both the first spacing adjustment mechanism and the second spacing adjustment mechanism are disposed on the shaft group support. The first spacing adjustment mechanism is connected to a plurality of first support shafts and is used to drive the first support shafts to move along a direction perpendicular to their own length. The second spacing adjustment mechanism is connected to a plurality of second support shafts and is used to drive the second support shafts to move along a direction perpendicular to their own length.

[0011] The first support shaft is moved along its length by the first spacing adjustment mechanism, and the second support shaft is moved along its length by the second spacing adjustment mechanism, thereby adjusting the distance between the first support shaft and the second support shaft, that is, the size of the gap between the first support shaft and the second support shaft, so as to accommodate fruits of different sizes.

[0012] Optionally, the first spacing adjustment mechanism includes a first pull rod, and the second spacing adjustment mechanism includes a second pull rod. The first pull rod is connected to a plurality of first support shafts, and the second pull rod is connected to a plurality of second support shafts.

[0013] By pulling the first lever, the first lever causes multiple first support shafts to move synchronously, thereby adjusting the position of the first support shaft; when it is necessary to adjust the position of the second support shaft, by pulling the second lever, the second lever causes multiple second support shafts to move synchronously, thereby adjusting the position of the second support shaft.

[0014] Optionally, the shaft assembly support is provided with a plurality of baffles, with one baffle provided every other gap, and each baffle located above one of the gaps.

[0015] During the process of adjusting the positions of the first support shaft and the second support shaft using the first and second pull rods respectively, when the gap between the first support shaft and one of the adjacent second support shafts is adjusted to a distance that allows small fruits to fall, the gap between the first support shaft and the other adjacent second support shaft will become larger. At this time, large fruits are more likely to fall through the gap. Therefore, a baffle is set above the gap to prevent fruits from falling through the gap.

[0016] Optionally, the small fruit removal machine further includes a first chute mechanism, which includes a first chute support and a first chute body; the first chute body is disposed on the first chute support and is connected to the first support shaft group and the second support shaft group; the first chute body is provided with a plurality of first slides, each first slide corresponding to a gap.

[0017] Water flows out from the tail end of the previous stage equipment, carrying the fruit into the main body of the first chute. The fruit then flows through the main body of the first chute into the space between the first support shaft and the second support shaft, where the small fruit falls out through the gap between the first support shaft and the second support shaft.

[0018] Optionally, the small fruit removal machine further includes a water tank mechanism, which includes a water tank support and a buffer tank. The buffer tank is disposed on the water tank support. A plurality of first support shafts and a plurality of second support shafts are inclined, and the inclination directions of the first support shafts and the second support shafts are consistent. The buffer tank is connected to the lowest inclined end of the first support shafts and the second support shafts.

[0019] When the fruit after removing small fruits flows from the lowest inclined end of the first and second support shafts into the buffer pool, the buffer pool can buffer the fruit to a certain extent, preventing the fruit from being damaged by collision, and the buffer pool can also clean the fruit.

[0020] Optionally, a plurality of guide plates are arranged sequentially in the buffer pool, and there are channels between adjacent guide plates for the fruit to pass through.

[0021] Multiple deflectors divide the buffer pool into multiple channels for fruit to pass through. When the fruit arrives at the buffer pool and flows to the next stage of the mechanism, the multiple channels can divert the fruit, thereby preventing the fruit from accumulating in one place in the buffer pool and causing normal transportation problems.

[0022] Optionally, the small fruit removal machine further includes a second chute mechanism, which includes a second chute support and a second chute body; the second chute body is disposed on the second chute support and is connected to the buffer pool; the second chute body is provided with a plurality of second slides.

[0023] The fruit flows from the buffer pool to the main body of the second chute, and then flows through the main body of the second chute to facilitate its transfer to the next stage mechanism.

[0024] Optionally, the small fruit removal machine further includes a conveying mechanism, which is disposed below the first support shaft group and the second support shaft group, for transporting small fruits that fall from the gap.

[0025] Small fruits falling from the gaps fall onto the conveyor mechanism, which then transports the fruit to the next workstation. Attached Figure Description

[0039] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0040] Please refer to Figures 1-3 An embodiment of this application provides a small fruit removal machine including a shaft assembly bracket 100, a first support shaft assembly 200, a second support shaft assembly 300, a first drive mechanism 400, and a second drive mechanism 500; both the first drive mechanism 400 and the second drive mechanism 500 are disposed on the shaft assembly bracket 100; the first support shaft assembly 200 includes a plurality of first support shafts 210, and the second support shaft assembly 300 includes a plurality of second support shafts 310, the plurality of first support shafts 210 and the plurality of second support shafts 310 being alternately disposed on the shaft assembly bracket 100, the first support shafts 210 and the second support shafts 310 being disposed alternately ... There is a gap 230 between the support shafts 310; the first drive mechanism 400 is drivenly connected to the plurality of first support shafts 210 to drive the plurality of first support shafts 210 to rotate; the second drive mechanism 500 is drivenly connected to the plurality of second support shafts 310 to drive the plurality of second support shafts 310 to rotate; the rotation direction of the plurality of first support shafts 210 is opposite to the rotation direction of the plurality of second support shafts 310; the plurality of first support shafts 210 and the plurality of second support shafts 310 are all inclined, and the inclination direction of the first support shafts 210 is the same as the inclination direction of the second support shafts 310.

[0041] It should be noted that the first support shaft 210 and the second support shaft 310 are arranged alternately in sequence, and the arrangement direction of the first support shaft 210 and the second support shaft 310 is perpendicular to the fruit conveying direction; the gap 230 between the first support shaft 210 and the second support shaft 310 is used for small fruits to fall, and the tilt direction of the first support shaft 210 is the length direction of the first support shaft 210.

[0042] During the process of removing small fruits, as the fruit passes through the gap 230 between the first support shaft 210 and the second support shaft 310, the small fruits fall through the gap 230 between the first support shaft 210 and the second support shaft 310. The first drive mechanism 400 drives multiple first support shafts 210 to rotate around their own central axis, and the second drive mechanism 500 drives multiple second support shafts 310 to rotate around their own central axis. The first support shafts 210 and the second support shafts 310 rotate towards each other, and the large fruits move between the first support shafts 210 and the second support shafts 310 along the inclined direction of the first support shaft 210. In this process, small fruits and large fruits are sorted, achieving the effect of removing small fruits.

[0043] In an optional embodiment, both the first drive mechanism 400 and the second drive mechanism 500 include a motor, a chain, and a sprocket assembly. A plurality of first support shafts 210 are each provided with a first support shaft sprocket 220, and a plurality of second support shafts 310 are each provided with a second support shaft sprocket 320. The motor is connected to the sprocket assembly for transmission, and the chain cooperates with the sprocket assembly. The plurality of first support shaft sprockets 220 are arranged along the same straight line, and the plurality of second support shaft sprockets 320 are arranged along the same straight line. The plurality of first support shaft sprockets 220 cooperate with the chain in the first drive mechanism 400, and the plurality of second support shaft sprockets 320 cooperate with the chain in the second drive mechanism 500.

[0044] It should be noted that the first drive mechanism 400 includes a set of motor, chain, and sprocket assembly. The motor in the first drive mechanism 400 is connected to the sprocket assembly for transmission, the chain cooperates with the sprocket assembly, and multiple first support shaft sprockets 220 cooperate with the chain in the first drive mechanism 400. The second drive mechanism 500 includes another set of motor, chain, and sprocket assembly. The motor in the second drive mechanism 500 is connected to the sprocket assembly for transmission, the chain cooperates with the sprocket assembly, and multiple second support shaft sprockets 320 cooperate with the chain in the second drive mechanism 500. The chain can be a short-pitch roller chain.

[0045] When it is necessary to drive the first support shaft 210 and the second support shaft 310 to rotate, one set of motor, chain and sprocket assembly is used to drive multiple first support shaft sprockets 220 to rotate, thereby driving multiple first support shafts 210 to rotate synchronously. Another set of motor, chain and sprocket assembly is used to drive multiple second support shaft sprockets 320 to rotate, thereby driving multiple second support shafts 310 to rotate synchronously, thus facilitating the transportation of large fruits.

[0046] In addition, the small fruit rejection machine also includes a self-tensioning mechanism that can automatically adjust the tension of the sprocket assembly.

[0047] In an optional embodiment, the small fruit removal machine further includes a first spacing adjustment mechanism 600 and a second spacing adjustment mechanism 700. Both the first spacing adjustment mechanism 600 and the second spacing adjustment mechanism 700 are mounted on the shaft assembly bracket 100. The first spacing adjustment mechanism 600 is connected to a plurality of first support shafts 210 and is used to drive the first support shafts 210 to move along a direction perpendicular to their own length. The second spacing adjustment mechanism 700 is connected to a plurality of second support shafts 310 and is used to drive the second support shafts 310 to move along a direction perpendicular to their own length.

[0048] It should be noted that the moving direction of the first support shaft 210 and the moving direction of the second support shaft 310 are both horizontal.

[0049] The first support shaft 210 is moved along its own length by the first spacing adjustment mechanism 600, and the second support shaft 310 is moved along its own length by the second spacing adjustment mechanism 700, thereby adjusting the distance between the first support shaft 210 and the second support shaft 310, that is, the size of the gap 230 between the first support shaft 210 and the second support shaft 310, so as to accommodate fruits of different sizes.

[0050] In an optional embodiment, the first spacing adjustment mechanism 600 includes a first pull rod 610, and the second spacing adjustment mechanism 700 includes a second pull rod 710. The first pull rod 610 is connected to a plurality of first support shafts 210, and the second pull rod 710 is connected to a plurality of second support shafts 310.

[0051] It should be noted that the first pull rod 610 is connected to multiple first support shafts 210 via a first connecting plate 620, and the first connecting plate 620 is slidably engaged with the shaft group bracket 100 via a slide rail; the second pull rod 710 is connected to multiple second support shafts 310 via a second connecting plate 720, and the second connecting plate 720 is slidably engaged with the shaft group bracket 100 via a slide rail; both the ends of the first pull rod 610 and the second pull rod 710 are provided with handles.

[0052] When the position of the first support shaft 210 needs to be adjusted, the first pull rod 610 is pulled by the handle. The first pull rod 610 causes the first connecting plate 620 to slide on the shaft group bracket 100. The first connecting plate 620 causes multiple first support shafts 210 to move synchronously, thereby adjusting the position of the first support shaft 210. When the position of the second support shaft 310 needs to be adjusted, the second pull rod 710 is pulled by the handle. The second pull rod 710 causes the second connecting plate 720 to slide on the shaft group bracket 100. The second connecting plate 720 causes multiple second support shafts 310 to move synchronously, thereby adjusting the position of the second support shaft 310.

[0053] In other embodiments, the first pitch adjustment mechanism 600 and the second pitch adjustment mechanism 700 may also be a lead screw slider mechanism or other driving mechanism, as long as they can drive the first support shaft 210 and the second support shaft 310 to move.

[0054] In an optional embodiment, the shaft support 100 is provided with a plurality of baffles 110, with a baffle 110 provided every other gap 230, and each baffle 110 being located above one of the gaps 230.

[0055] It should be noted that the baffle 110 is elongated, and the length direction of the baffle 110 is consistent with the length direction of the first support shaft 210. For one of the first support shafts 210, a second support shaft 310 is respectively provided on both sides of the first support shaft 210. The gap 230 between the first support shaft 210 and one of the adjacent second support shafts 310 is used for small fruits to fall. The baffle 110 mentioned above is provided above the gap 230 between the first support shaft 210 and the other adjacent second support shaft 310. The baffle 110 is used to prevent fruits from falling through the gap 230.

[0056] During the process of adjusting the positions of the first support shaft 210 and the second support shaft 310 using the first pull rod 610 and the second pull rod 710 respectively, when the gap 230 between the first support shaft 210 and one of the adjacent second support shafts 310 is adjusted to a distance that allows small fruits to fall, the gap 230 between the first support shaft 210 and the other adjacent second support shaft 310 will become larger. At this time, large fruits are more likely to fall through the gap 230. Therefore, a baffle 110 is set above the gap 230 to prevent fruits from falling through the gap 230.

[0057] Please see Figure 4 In an optional embodiment, the small fruit rejection machine further includes a first chute mechanism 800, which includes a first chute support 810 and a first chute body 820. The first chute body 820 is disposed on the first chute support 810 and is connected to the first support shaft group 200 and the second support shaft group 300. The first chute body 820 is provided with a plurality of first slides 821, each first slide 821 corresponding to a gap 230.

[0058] It should be noted that each first slide 821 includes two connected V-shaped grooves with different V-shaped opening sizes. The V-shaped groove with the smaller opening is directly opposite a gap 230 for small fruits to fall into. The V-shaped groove with the smaller opening is inclined downward to facilitate the flow of fruit between the first support shaft 210 and the second support shaft 310.

[0059] Water flows out from the tail end of the previous stage equipment, carrying the fruit into the first chute body 820. The fruit is first distributed in the V-shaped grooves with larger openings, and then flows into the space between the first support shaft 210 and the second support shaft 310 through the V-shaped grooves with smaller openings. The small fruit then falls out from the gap 230 between the first support shaft 210 and the second support shaft 310.

[0060] Please see Figure 5In an optional embodiment, the small fruit removal machine also includes a water tank mechanism 900, which includes a water tank support 910 and a buffer tank 920. The buffer tank 920 is disposed on the water tank support 910 and is connected to the lowest inclined end of the first support shaft 210 and the second support shaft 310.

[0061] It should be noted that the interior of the buffer pool 920 has an inverted trapezoidal structure, which can store water. When the fruit after removing small fruits flows from the lowest inclined end of the first support shaft 210 and the second support shaft 310 into the buffer pool 920, the buffer pool 920 can buffer the fruit to a certain extent to prevent the fruit from being damaged by collision. The buffer pool 920 can also wash the fruit. After the water flows through the first support shaft 210, the second support shaft 310, and the buffer pool 920, it seeps downwards and enters other equipment for filtration and reuse.

[0062] In an optional embodiment, a plurality of guide plates 921 are arranged sequentially inside the buffer pool 920, and there are channels between adjacent guide plates 921 for the fruit to pass through.

[0063] It should be noted that multiple guide plates 921 divide the buffer pool 920 into multiple channels for fruit to pass through. When the fruit arrives at the buffer pool 920 and flows to the next level mechanism, the multiple channels can divert the fruit, thereby preventing the fruit from accumulating in one place in the buffer pool 920 and causing the fruit to be unable to be transported normally.

[0064] Please see Figure 6 In an optional embodiment, the small fruit removal machine further includes a second chute mechanism 930, which includes a second chute support 931 and a second chute body 932. The second chute body 932 is disposed on the second chute support 931 and is connected to the buffer pool 920. A plurality of second slides 933 are provided on the second chute body 932.

[0065] It should be noted that each second slide 933 also includes two interconnected V-shaped grooves. The two V-shaped grooves have different V-shaped opening sizes. The V-shaped groove with the larger opening faces the buffer pool 920, and the V-shaped groove with the smaller opening faces the next stage mechanism. The V-shaped groove with the smaller opening is inclined downward to facilitate the flow of fruit to the next stage mechanism. A perforated D-shaped sealing strip is provided between the second slide body 932 and the buffer pool 920 to achieve a sealing effect.

[0066] After the small fruits are removed, the fruits and some water flow from the first support shaft 210 and the second support shaft 310 to the buffer pool 920. This pool stores a certain amount of water to wash the fruits and also provides a certain buffering effect. Then, the fruits will move to the second chute body 932 under the power of the water flow and the gravitational potential energy. Most of the water seeps down through the gap 230 between the first support shaft 210 and the second support shaft 310, and the water that overflows into the buffer pool 920 is collected, filtered, and recycled by other equipment at the bottom (e.g., a stainless steel water tank).

[0067] In an optional embodiment, the small fruit removal machine further includes a conveying mechanism 940, which is disposed below the first support shaft group 200 and the second support shaft group 300, for transporting small fruits that fall from the gap 230.

[0068] It should be noted that the top of the conveying mechanism 940 is equipped with a funnel-shaped guide plate. Small fruits falling from the gap 230 fall from this guide plate to the conveying mechanism 940, which can play a certain role in buffering and guiding the small fruits.

[0069] Optionally, the conveyor mechanism 940 can be a chain conveyor, belt conveyor, or other mechanism capable of conveying small fruits.

[0070] In summary, the embodiments of the present invention provide a small fruit removal machine. During the fruit conveying process, the fruit first passes through the first chute mechanism 800, which conveys the fruit to the first support shaft group 200 and the second support shaft group 300. Small fruits fall from the gap 230 between the first support shaft 210 and the second support shaft 310. Large fruits continue to be conveyed on the first support shaft 210 and the second support shaft 310. Subsequently, the large fruits flow into the buffer pool 920 for buffering and cleaning. Finally, the large fruits are conveyed to the next stage mechanism through the second chute mechanism 930. In this process, small fruits are removed, and the overall work efficiency is high.

[0071] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
