Description

Technical Field

[0001] The utility model relates to the technical field of agricultural fruit and vegetable separation, in particular to a fruit and vegetable separation device. Background Art

[0002] With the development of science and technology, agricultural fruit and vegetable picking technology has become more mature. High-end fruits and vegetables not only require good taste, but also have certain requirements on the quality of fruits and vegetables, such as cherries, lychees, longans, tomatoes, etc. When these fruits and vegetables are picked, they are often connected together by stalks or handles. In other words, the fruits are gathered into bunches, and these fruits need to be separated for screening and grading, and each fruit in some high-end fruits and vegetables must also maintain its corresponding separate stalk.

[0003] The Chinese invention patent with announcement number CN105962395B disclosed on November 17, 2020 a device and method for separating the stalks of fruits gathered in bunches, including a fruit receiving chamber, a suction inlet, a suction area, an impeller pump, a pipe, a channel and a narrow passage, wherein the fruit and liquid are placed in the fruit receiving chamber, and the fruit and liquid mixture gathered in bunches enters the suction area through the suction inlet. The impeller pump is started to inject high-speed liquid into the channel behind the suction area through the pipe, thereby forming a pressure suppression in the channel. The pressure suppression causes the liquid and fruit mixture in the fruit suction area to be brought to the narrow passage between the channel and the fruit suction area, thereby forming turbulence around the fruit. The turbulence washes the fruit and breaks the connection between the connected stalks, so that a single fruit can retain its corresponding individual stalk or stalk.

[0004] However, after the high-speed liquid is injected into the channel, it will cause greater pressure on the surface of fruits and vegetables, making the peel easily collapse or break, resulting in the fruits and vegetables becoming defective. Utility Model Content

[0005] The embodiment of the utility model aims to provide a fruit and vegetable separation device, in order to solve the technical problem in the prior art that when separating fruits and vegetables, high-speed liquid will cause greater pressure on the surface of fruits and vegetables, causing the surface of the peel to collapse or break, etc., resulting in the fruits and vegetables becoming defective.

[0006] In order to solve the above technical problems, the utility model provides a fruit and vegetable separation device, comprising:

[0007] frame;

[0008] A conveying mechanism, the conveying mechanism is installed on the frame and is used to convey fruits and vegetables;

[0009] Driving mechanism;

[0010] A cutting mechanism, wherein a plurality of the cutting mechanisms are arranged on the frame in parallel and at intervals, the output end of the driving mechanism is connected to the plurality of cutting mechanisms, each of the cutting mechanisms comprises a frame body and a stem cutting assembly, the stem cutting assembly is connected to the frame body, the stem cutting assembly comprises a first mounting rod, a second mounting rod, a rotating blade and a separator, the first mounting rod and the second mounting rod are sequentially mounted on the frame body along a fruit and vegetable conveying direction, the rotating blade is mounted on the first mounting rod, the output end of the driving mechanism can drive the first mounting rod to rotate so as to drive the rotating blade to rotate, the separator is mounted on the second mounting rod, the separator is in the shape of an elongated strip, the separator extends from the second mounting rod to the first mounting rod, and protrudes from the rotating blade, each of the separators and a corresponding one of the rotating blades are located in the same vertical plane, and each of the separators is located below a corresponding one of the rotating blades, and the separator is arranged to be inclined downward relative to a horizontal plane.

[0011] Through the above structure, when the connected cherries are conveyed through the conveying mechanism, the stems of the connected cherries will be blocked by the partition. As the fruit parts of the connected cherries continue to be conveyed, the stems of the connected cherries will be lifted by the outer surface of the partition until they are lifted below the rotating blade. The rotating blade will cut the stems of the connected cherries, so that the two independent cherries maintain their separate stems without causing damage to the surface of the cherries.

[0012] In some embodiments, the stem cutting assembly also includes a third mounting rod and a stop block, the third mounting rod is mounted on the frame, the first mounting rod is located between the second mounting rod and the third mounting rod, the stop block is mounted on the third mounting rod, the stop block and a corresponding one of the partitions and a corresponding one of the rotating blades are located in the same vertical plane, each of the stop blocks is located above a corresponding one of the partitions, and there is a pressing gap between the stop block and the partition.

[0013] Through the above structure, during the transmission of connected cherries, the fruit parts of the connected cherries may be blocked on the surface of the partition. Through the setting of the blocking block, the blocking block will block the fruit parts of the connected cherries, forcing the fruit parts of the connected cherries to fall off the surface of the partition to the transmission mechanism.

[0014] In some embodiments, the retaining block has an arc-shaped surface on a side facing the rotating blade, the rotating blade is circular, and the center of the arc-shaped surface coincides with the center of the rotating blade.

[0015] Through the above structure, a large number of connected cherries will be accompanied by a large amount of water during the transmission process. When the rotating blade cuts the connected cherry stems, the water will also splash as the rotating blade rotates. The setting of the arc surface can effectively avoid water splashing, prevent water from splashing onto other mechanisms and cause premature rusting of the fruit and vegetable separation device.

[0016] In some embodiments, the third mounting rod comprises a reference plane, the reference plane is located on a circumferential side wall of the third mounting rod, and the reference plane forms an adjustment angle with a horizontal plane.

[0017] Through the above structure, when the operator needs to know the inclination angle between the partition in the stem cutting assembly and the horizontal plane, he can measure the size of the adjustment angle through a protractor, and confirm whether the multiple partitions are parallel by comparing the adjustment angle sizes of multiple stem cutting assemblies, thereby ensuring that the stem cutting effects of multiple stem cutting assemblies are consistent.

[0018] In some embodiments, the third mounting rod is columnar, and the cross-section of the third mounting rod is a polygonal structure;

[0019] The stem cutting assembly also includes a mounting seat, the retaining block is connected to the mounting seat, the mounting seat is provided with a polygonal through hole, the mounting seat is sleeved on the third mounting rod, and the third mounting rod is against the hole wall of the polygonal through hole.

[0020] The above structure can prevent the mounting seat from slipping with the third mounting rod when the third mounting rod rotates, and can ensure that the multiple mounting seats sleeved on the third mounting rod rotate synchronously.

[0022] Through the above structure, the first seat body and the second seat body can be assembled and installed on the third installation rod along the opposite sides of the third installation rod, so as to improve the installation efficiency of the installation seat.

[0023] In some embodiments, the fruit and vegetable separation device also includes a linkage mechanism, which includes a linkage bracket, a linkage shaft, a first linkage rod and a second linkage rod. The linkage bracket is connected to the frame, and the linkage shaft is rotatably installed on the linkage bracket. The first linkage rod is connected to one end of the linkage shaft, and the first linkage rod is hinged to the second linkage rod; the stem cutting assembly also includes a connecting shaft, a linkage plate and an adjustment plate. The output end of the driving mechanism is connected to the connecting shaft, and the connecting shaft is penetrated through the linkage plate. The connecting shaft is connected to the first mounting rod, one end of the second mounting rod and one end of the third mounting rod are respectively connected to opposite sides of the linkage plate, one end of the first mounting rod is connected to the middle part of the linkage plate, and the linkage plate is connected to the adjustment plate. Multiple adjustment plates in the multiple stem cutting assemblies are all connected to the second linkage rod, and multiple stem cutting assemblies are located in the same transmission plane, and the second linkage rod is parallel to the transmission plane.

[0024] With the above structure, when the linkage shaft rotates, the first linkage rod and the second linkage rod change position accordingly, and the multiple adjustment plates in the multiple stem cutting assemblies also change position accordingly, so that the linkage plate rotates. While the linkage plate rotates, the second mounting rod and the third mounting rod also shift, and the partition located on the second mounting rod also changes position accordingly, so that the inclination angle of the partition relative to the horizontal plane changes, thereby changing the inclination angle of the partition with the horizontal plane, so that the stems of the connected cherries are raised higher. Alternatively, the stems of the connected cherries are blocked due to the excessive inclination angle of the partition with the horizontal plane, and cannot be further transported by the transport mechanism.

[0025] In some embodiments, the fruit and vegetable separation device also includes a lifting mechanism, which includes a handle, a locking nut, a screw rod, a connecting rod and a lifting member, the handle is connected to the screw rod, the locking nut is fixedly connected to the frame, the screw rod is passed through the locking nut, the screw rod and the locking nut are threadedly connected, one end of the screw rod facing away from the handle is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to the lifting member, the lifting member is sleeved on one end of the linkage shaft, and rotating the handle can cause the linkage shaft to rotate relative to the linkage bracket.

[0026] Through the above structure, a threaded connection is adopted between the locking nut and the screw rod, which can improve the adjustment accuracy and avoid the linkage shaft rotating too fast, resulting in too large an inclination angle between the partition and the horizontal plane, such as the end of the partition abutting against the transmission mechanism, causing the end of the partition to be worn.

[0027] In some embodiments, the separator includes a cutting groove, and the rotating blade is partially received in the cutting groove.

[0028] With the above structure, it is prevented that the stems of connected cherries pass through the gap between the rotating blade and the separator without being cut.

[0029] In some embodiments, the partition includes a partition part and a cutting part, the partition part and the cutting part are arranged in sequence along the fruit and vegetable conveying direction, the partition part is connected to the cutting part, the cross-sectional area of ​​the partition part gradually increases along the fruit and vegetable conveying direction, and the cutting groove is opened on the side of the cutting part facing the rotating blade.

[0030] Through the above structure, the partition not only has a guiding function, but also the stems of the connected cherries will be continuously lifted on the surface of the partition, and the fruit part of the connected cherries is always located on the conveying mechanism. As the stems of the connected cherries are lifted and moved to the cutting part, they are cut by the rotating blade accommodated in the cutting groove.

[0031] Compared with the prior art, in the embodiment of the utility model, the cherries connected by stems will be placed on the conveying mechanism and conveyed by the conveying mechanism. During the conveying process, the stems of the connected cherries will be blocked by the partition, and as the conveying mechanism continues to convey, the stems of the connected cherries will be continuously raised along the surface of the partition, and the fruit parts of the connected cherries will continue to be located on the conveying mechanism. As the conveying mechanism continues to convey, the stems of the connected cherries are conveyed to the rotating blade, and the rotating blade cuts the stems of the connected cherries, thereby achieving two independent cherries while maintaining their separate stems, and without damaging the surface of the cherries.

[0048] The fruit and vegetable separation device 100 provided in one embodiment of the utility model includes a frame 10, a conveying mechanism 20, a driving mechanism 30 and a cutting mechanism 40. The conveying mechanism 20 is installed on the frame 10. The conveying mechanism 20 is used to convey fruits and vegetables. A plurality of cutting mechanisms 40 are arranged on the frame 10 in parallel and at intervals. The output end of the driving mechanism 30 is connected to the plurality of cutting mechanisms 40. Each cutting mechanism 40 includes a frame body 41 and a stem cutting assembly 42. The stem cutting assembly 42 is connected to the frame body 41. The stem cutting assembly 42 includes a first mounting rod 421, a second mounting rod 422, a rotating blade 423 and a separator 424. The first mounting rod 421 and the second mounting rod 422 are sequentially mounted on the frame body 41 along the fruit and vegetable conveying direction. On the body 41, the rotating blade 423 is installed on the first mounting rod 421, the output end of the driving mechanism 30 is connected to the first mounting rod 421, the driving mechanism 30 can drive the first mounting rod 421 to rotate to drive the rotating blade 423 to rotate, the partition 424 is installed on the second mounting rod 422, the partition 424 is in the shape of a slender strip, the partition 424 extends from the second mounting rod 422 to the first mounting rod 421, and protrudes from the rotating blade 423, each partition 424 and a corresponding rotating blade 423 are located in the same vertical plane, and each partition 424 is located below a corresponding rotating blade 423, and the partition 424 is inclined downward relative to the horizontal plane.

[0049] In this embodiment, the fruit and vegetable separation device 100 can separate the stems or handles of fruits gathered in a bunch, and each independent fruit can keep its corresponding independent stem or handle. For ease of understanding, the embodiment of the utility model is described by taking cherries with two stems connected as an example.

[0050] A plurality of cutting mechanisms 40 are arranged in parallel and at intervals on the frame 10 to form a stem separation area 50 for separating connected cherries, thereby improving the separation rate of a large number of connected cherries.

[0051] Specifically, two cherries with connected stems are conveyed to one side of the partition 424 on the conveying mechanism 20, and the stems of the connected cherries are blocked by the partition 424. As the connected cherries continue to be transported by the conveying mechanism 20, the stems are lifted by the outer surface of the partition 424. The cherries continue to shift to the bottom of a corresponding rotating blade 423 under the influence of the conveying mechanism 20, and the rotating blade 423 cuts the stems of the connected cherries, so that the two independent cherries maintain their separate stems without damaging the surface of the cherries.

[0052] The partition 424 is in the shape of an elongated strip. The purpose of such a setting is that if the partition 424 is in the shape of a thick cylinder, then the connected cherries may be blocked on the upper surface of the partition 424. At this time, the conveying mechanism 20 cannot continue to convey the connected cherries, making it difficult for the rotating blade 423 to cut the stems of the connected cherries.

[0053] Please also read Figure 4 and Figure 5 , Figure 5 yes Figure 4 A cross-sectional view of the cutting mechanism. In one embodiment, the stem cutting assembly 42 also includes a third mounting rod 425 and a stop block 426. The third mounting rod 425 is mounted on the frame 41. The first mounting rod 421 is located between the second mounting rod 422 and the third mounting rod 425. The stop block 426 is installed on the third mounting rod 425. The stop block 426 and a corresponding partition 424 and a corresponding rotating blade 423 are located in the same vertical plane. Each stop block 426 is located above a corresponding partition 424, and a pressing gap 60 is provided between the stop block 426 and the partition 424.

[0054] Specifically, the stop block 426 is roughly in the shape of a rectangular block, and the stop block 426 extends toward the partition 424. There is a pressing gap 60 between the lower bottom surface of the stop block 426 and the upper surface of the partition 424. The purpose of this arrangement is that during the transmission of the connected cherries, the fruit part of the connected cherries may be blocked by the partition 424 and stop on the partition 424. The fruit part of the connected cherries has inertia and will continue to move along the surface of the partition 424. Through the setting of the stop block 426, the fruit part of the connected cherries moving along the surface of the partition 424 can be blocked, forcing the fruit part of the connected cherries to fall off the surface of the partition 424 to the transmission mechanism 20.

[0055] Moreover, when the highest point of the stems of the connected cherries is higher than the pressing gap 60, but the stem part is lower than the pressing gap 60, the blocking block 426 will press the stem to ensure that the stems of the connected cherries are cut through the pressing gap 60.

[0056] In some other embodiments, in order to further ensure that the fruit parts of the connected cherries are not cut, the size of the cherries can be confirmed in advance, and the size of the pressing gap 60 between the stop block 426 and the partition 424 can be adjusted to prevent the fruit parts of the connected cherries from passing through the pressing gap 60.

[0057] In some other embodiments, the divider 424 may be hinged to the second mounting rod 422, so that the inclination angle between the divider 424 and the horizontal plane can be adjusted to cut cherry stems or handles of different sizes.

[0058] In one embodiment, the side of the blocking block 426 facing the rotating blade 423 has an arc surface 4261 . The rotating blade 423 is circular, and the center of the arc surface 4261 coincides with the center of the rotating blade 423 .

[0059] Specifically, the circle of the rotating blade 423 coincides with the center of the arc surface 4261, that is, the circle where the rotating blade 423 is located is concentric with the circle where the arc surface 4261 is located. In simple terms, the rotating blade 423 and the arc surface 4261 have the same center but different radii. The purpose of this arrangement is that a large amount of water will be accompanied by cherries during the transmission process, and the water will also splash as the rotating blade 423 rotates during the cutting process of the stems of the cherries. The arc surface 4261 can block part of the splashing water, that is, effectively avoid water splashing, and prevent water from splashing onto other mechanisms and causing the fruit and vegetable separation device 100 to rust prematurely.

[0060] See also Figure 6 , Figure 6 It is a structural schematic diagram of the third mounting rod and the mounting seat of the cutting mechanism.

[0061] In one embodiment, the third mounting rod 425 includes a reference plane 4251 , which is located on a circumferential side wall of the third mounting rod 425 , and the reference plane 4251 forms an adjustment angle with a horizontal plane.

[0062] Specifically, in actual application operation, taking two adjacent and spaced-apart cutting assemblies 42 as an example, when the operator adjusts the inclination angle between a partition 424 in one cutting assemblies 42 and the horizontal plane, the operator can use a protractor to measure the size of the adjustment angle. By comparing the sizes of the adjustment angles of multiple cutting assemblies 42, it is confirmed whether the multiple partitions 424 are parallel, thereby ensuring that the cutting effects of the multiple cutting assemblies 42 are consistent.

[0063] In one embodiment, the third mounting rod 425 is columnar, and the cross-section of the third mounting rod 425 is a polygonal structure; the stem cutting assembly 42 also includes a mounting seat 420, and the stop block 426 is connected to the mounting seat 420. The mounting seat 420 is provided with a polygonal through hole, and the mounting seat 420 is sleeved on the third mounting rod 425, and the third mounting rod 425 is against the hole wall of the polygonal through hole.

[0064] Specifically, polygonal columnar rods are more convenient for manufacturing than irregular columnar rods. In this embodiment, the cross section of the third mounting rod 425 is a regular hexagon, and the reference plane 4251 is located on the outer side of the third mounting rod 425. The mounting seat 420 is sleeved on the third mounting rod 425, and the polygonal through hole is a regular hexagonal through hole. The purpose of such a setting is that if the cross section of the third mounting rod 425 is circular, the polygonal through hole will also be correspondingly set as a circular through hole. Then, when the mounting seat 420 is sleeved on the third mounting rod 425, the hole wall of the circular through hole and the outer side surface of the third mounting rod 425 are prone to slippage, causing the mounting seat 420 to rotate along the surface of the third mounting rod 425, that is, the pressing gap 60 between the blocking block 426 and the partition 424 will change accordingly, and the different pressing gaps 60 in the multiple cutting mechanisms 40 will result in different effects of separating the connected cherry stems by the multiple cutting mechanisms 40, thereby resulting in poor effect of separating the cherry stems by the fruit and vegetable separation device 100. The third mounting rod 425 adopts a polygonal columnar structure, and the mounting seat 420 is provided with a polygonal through hole. The third mounting rod 425 abuts against the hole wall of the polygonal through hole, which can avoid slipping between the mounting seat 420 and the third mounting rod 425 when the third mounting rod 425 rotates, and can ensure that multiple mounting seats 420 mounted on the third mounting rod 425 rotate synchronously.

[0065] In one embodiment, the mounting base 420 includes a first base body 4201 and a second base body 4202 . The first base body 4201 and the second base body 4202 are assembled and mounted on a third mounting rod 425 , and the second base body 4202 is connected to a blocking block 426 .

[0066] Specifically, the first seat body 4201 and the second seat body 4202 can be assembled and installed on the third mounting rod 425 along the opposite sides of the third mounting rod 425 to improve the installation efficiency of the mounting seat 420. Moreover, the first seat body 4201 and the second seat body 4202 are fixed by screws. In this embodiment, the first seat body 4201 and the second seat body 4202 are fixed by the first screw and the second screw, and the third mounting rod 425 is located between the first screw and the second screw. A part of the polygonal through hole is opened in the first seat body 4201, and another part of the polygonal through hole is opened in the second seat body 4202. The first seat body 4201 and the second seat body 4202 are assembled and enclosed to form a polygonal through hole.

[0067] In some other embodiments, a screw may be used to fix the first base body 4201 and the second base body 4202 , then a mounting hole needs to be opened on the third mounting rod 425 , and the screw is sequentially passed through the first base body 4201 , the mounting hole, and the second base body 4202 .

[0068] In some other embodiments, the mounting seat 420 may be an integrated structure, and the mounting seat 420 may be locked onto the third mounting rod 425 by a screw, and the screw passes through the mounting seat 420 and the third mounting rod 425 .

[0069] See also Figure 7 , Figure 7 yes Figure 4 Schematic diagram of the structure of the first mounting rod, rotating blade, second mounting rod and separator of the cutting mechanism.

[0070] In one embodiment, the separator 424 includes a cutting groove 4241 , and the rotating blade 423 is partially received in the cutting groove 4241 .

[0071] Specifically, the rotating blade 423 is located above the partition 424, and a cutting groove 4241 is formed on the upper surface of the partition 424, so that the rotating blade 423 is partially accommodated in the cutting groove 4241. The purpose of such a setting is that if the rotating blade 423 is above the partition 424 and there is a gap, the stems of the connected cherries may pass through the gap during the transmission process and are difficult to be cut by the rotating blade 423. By partially accommodating the rotating blade 423 in the cutting groove 4241, it is ensured that the connected cherries are cut by the rotating blade 423.

[0072] In one embodiment, the partition 424 includes a partition portion 4242 and a cutting portion 4243, which are arranged in sequence along the cherry conveying direction, the partition portion 4242 is connected to the cutting portion 4243, and the cross-sectional area of ​​the partition portion 4242 gradually increases along the cherry conveying direction, and the cutting groove 4241 is opened on the side of the cutting portion 4243 facing the rotating blade 423.

[0073] Specifically, the partition portion 4242 and the cutting portion 4243 are manufactured integrally, the partition portion 4242 is roughly conical, and the cutting portion 4243 is roughly cylindrical. The connected cherry stems will be gradually lifted along the upper surface of the partition portion 4242, so that while the connected cherry stems are lifted, the fruit bodies of the connected cherries themselves are always located on the conveying mechanism 20. As the stems of the connected cherries are lifted and moved to the cutting portion 4243, the rotating blade 423 will cut the cherry stems.

[0075] It should be noted here that, in the present embodiment, the driving mechanism 30 includes a driving motor 31, a driving shaft 32 and a transmission belt 33, wherein the output end of the driving motor 31 is connected to the driving shaft 32, the transmission belt 33 is sleeved on the driving shaft 32, and the driving shaft 32 drives the transmission belt 33 to rotate. For the sake of convenience of explanation, three first mounting rods 421 are taken as an example here, namely the first first mounting rod 421, the second first mounting rod 421 and the third first mounting rod 421, and the first first mounting rod 421, the second second mounting rod 422 and the third first mounting rod 421 are arranged in sequence in a direction gradually away from the driving motor 31.

[0076] The transmission belt 33 is sleeved on one end of the first first mounting rod 421 to drive the first first mounting rod 421 to rotate. The driving mechanism 30 also includes a first linkage belt 34 and a second linkage belt 35. The first linkage belt 34 is sleeved on the other end of the first first mounting rod 421, and the first linkage belt 34 is also sleeved on the other end of the second first mounting rod 421 to drive the second first mounting rod 421 to rotate. The second linkage belt 35 is sleeved on one end of the second first mounting rod 421, and the second linkage belt 35 is also sleeved on one end of the third first mounting rod 421 to drive the third first mounting rod 421 to rotate. The purpose of this arrangement is to ensure that one driving motor 31 can drive multiple first mounting rods 421 to rotate, and to ensure that the rotation speeds of multiple first mounting rods 421 are the same.

[0077] For easier understanding of the transmission mode, refer to Fig.10 , Fig.10 yes Figure 8 A simplified schematic diagram of the middle driving mechanism driving the first mounting rod to rotate.

[0078] Specifically, the three rods A, B, and C represent the first first mounting rod 421, the second first mounting rod 421, and the third first mounting rod 421, respectively; the transmission belt 33 is sleeved on the a end of the A rod, the first linkage belt 34 is sleeved on the b end of the A rod and the b end of the B rod, and the second linkage belt 35 is sleeved on the a end of the B rod and the a end of the C rod.

[0079] In some other embodiments, a plurality of driving motors 31 may be provided, and each driving motor 31 is connected to a corresponding first mounting rod 421 .

[0080] Please refer to Figure 8 and Fig. 9In one embodiment, the fruit and vegetable separation device 100 further includes a linkage mechanism 70, the linkage mechanism 70 includes a linkage bracket 71, a linkage shaft 72, a first linkage rod 73 and a second linkage rod 74, the linkage bracket 71 is connected to the frame 10, the linkage shaft 72 is rotatably mounted on the linkage bracket 71, the first linkage rod 73 is connected to one end of the linkage shaft 72, and the first linkage rod 73 is hinged to the second linkage rod 74; the stem cutting assembly 42 further includes a connecting shaft 427, a linkage plate 428 and an adjusting plate 429, and the output end of the driving mechanism 30 is connected to the ... Shaft 427, connecting shaft 427 is passed through linkage plate 428, connecting shaft 427 is connected to the first mounting rod 421, one end of the second mounting rod 422 and one end of the third mounting rod 425 are respectively connected to the opposite sides of the linkage plate 428, one end of the first mounting rod 421 is connected to the middle of the linkage plate 428, the linkage plate 428 is connected to the adjustment plate 429, and the multiple adjustment plates 429 in the multiple stem cutting assemblies 42 are all connected to the second linkage rod 74, the multiple stem cutting assemblies 42 are located in the same transmission plane, and the second linkage rod 74 is parallel to the transmission plane.

[0081] Specifically, the linkage shaft 72 is rotatably mounted on the linkage bracket 71, so that the linkage shaft 72 can rotate relative to the linkage bracket 71, and the linkage shaft 72 is connected to the first linkage rod 73, so that when the linkage shaft 72 rotates, the first linkage rod 73 also rotates with the linkage shaft 72, and the first linkage rod 73 is hinged with the second linkage rod 74, so that the second linkage rod 74 shifts with the rotation of the first linkage rod 73. The connecting shafts 427 in the multiple stem cutting assemblies 42 are all connected to the transmission belt 33, and the transmission method is consistent with the above, so as to ensure that the rotation speed of the multiple connecting shafts 427 is the same when the driving motor 31 is driven. The connecting shaft 427 is penetrated by the linkage plate 428, and the linkage plate 428 is connected to the adjustment plate 429. The adjustment plate 429 in the multiple stem cutting assemblies 42 is fixedly connected to the second linkage rod 74 by screws. The purpose of such arrangement is that when the linkage shaft 72 rotates, the first linkage rod 73 and the second linkage rod 74 change their positions accordingly, and the adjustment plates 429 in the plurality of stem cutting assemblies 42 also change their positions accordingly, so that the linkage plate 428 rotates, and the rotation axis of the linkage plate 428 is consistent with the axis of the first mounting rod 421; when the linkage plate 428 rotates, the second mounting rod 422 and the third mounting rod 425 also shift accordingly, and the partition 424 changes with the position change of the second mounting rod 422, so that the inclination angle of the partition 424 relative to the horizontal plane changes. Thus, the inclination angle of the partition 424 with the horizontal plane is changed, so that the height of the stems of the connected cherries is raised higher. Alternatively, by reducing the inclination angle of the partition 424 with the horizontal plane, it is avoided that the stems of the connected cherries are blocked and cannot be further transported by the conveying mechanism 20 due to the excessive inclination angle of the partition 424 with the horizontal plane.

[0082] Moreover, multiple stem cutting assemblies 42 are located in the same transmission plane, and the second linkage rod 74 is parallel to the transmission plane. The purpose of this arrangement is to ensure that the inclination angles between the partitions 424 in the multiple stem cutting assemblies 42 and the transmission mechanism 20 are the same, thereby ensuring that the cutting effect of the rotating blade 423 is the same.

[0083] In addition, during the adjustment of the linkage plate 428, the separator 424 and the stopper 426 rotate simultaneously, which can ensure that the size of the pressing gap 60 remains unchanged, that is, after the linkage plate 428 rotates, cherries of the same size do not need to adjust the size of the pressing gap 60. If the size of the pressing gap 60 changes, cherries of the same size may have difficulty passing through the changed pressing gap 60 due to the oversized stem size.

[0084] In this embodiment, the linkage mechanism 70 further includes a third linkage rod 75, which is located between the first linkage rod 73 and the second linkage rod 74. One end of the third linkage rod 75 is hinged to one end of the first linkage rod 73, and the other end of the third linkage rod 75 is hinged to one end of the second linkage rod 74. When the first linkage rod 73 moves, the third linkage rod 75 will also move accordingly, and the third linkage rod 75 drives the second linkage rod 74 to move. The third linkage rod 75 is a short rod, and the second linkage rod 74 is a long rod. The purpose of such a setting is to make the movement of the second linkage rod 74 more precise, thereby making the angle adjusted by the partition 424 more precise.

[0085] In one embodiment, the fruit and vegetable separation device 100 also includes a lifting mechanism 80, which includes a handle 81, a locking nut 82, a screw rod 83, a connecting rod 84 and a lifting member 85. The handle 81 is connected to the screw rod 83, the locking nut 82 is fixedly connected to the frame 10, the screw rod 83 is passed through the locking nut 82, the screw rod 83 is threadedly connected to the locking nut 82, one end of the screw rod 83 facing away from the handle 81 is hinged to one end of the connecting rod 84, and the other end of the connecting rod 84 is hinged to the lifting member 85. The lifting member 85 is sleeved on one end of the linkage shaft 72, and rotating the handle 81 can cause the linkage shaft 72 to rotate relative to the linkage bracket 71.

[0086] Specifically, when the handle 81 is turned, the corresponding screw rod 83 also rotates accordingly, and the screw rod 83 is threadedly connected with the locking nut 82, and the locking nut 82 is fixed on the frame 10. At this time, the screw rod 83 moves up and down relative to the locking nut 82, and the screw rod 83 can drive the connecting rod 84 to move; at the same time, the connecting rod 84 drives the lifting member 85 to move, and the lifting member 85 drives the linkage shaft 72 to rotate. When the linkage shaft 72 rotates, it can drive the second linkage rod 74 to move, so as to adjust the inclination angle of the partition 424 in the multiple stem cutting assemblies 42 and the horizontal plane. The purpose of this setting is that the locking nut 82 and the screw rod 83 are threadedly connected to improve the adjustment accuracy, so as to avoid the linkage shaft 72 rotating too fast, resulting in the partition 424 and the horizontal plane The angle is too large, such as the partition 424 abuts against the transmission mechanism 20, causing the end of the partition 424 to wear.

[0087] In some other embodiments, the fruit and vegetable separation device 100 also includes a lifting mechanism, which is connected to the frame 10, and the frame body 41 in the stem cutting assembly 42 is connected to the frame 10. The lifting mechanism can drive the frame 10 to move in the vertical direction, so that the stem cutting assembly 42 also moves in the vertical direction to change the gap between the partition 424 and the conveying mechanism 20.
