Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting, and in particular to a fruit cup flipping device, a sorting device, and a fruit and vegetable sorting machine. Background Technology

[0002] As people pursue a higher quality of life, more and more people are demanding higher quality fruits and vegetables, making fruit and vegetable sorting an important technology.

[0003] To improve production efficiency, automated fruit and vegetable sorting has become a common practice. In this process, fruit cups are often used for transfer. It's important to note that fruits and vegetables are placed in the fruit cups, which are then positioned on guide rails. The cups move along these rails, and once they reach a designated position, a flipping device flips them over, causing the fruits and vegetables to fall out.

[0004] The most common method for fruit cup flipping devices is to use a solenoid valve to strike the fruit cup. Currently, the solenoid valve assembly is generally mounted on a mounting base, which is detachably connected to a guide rail. For ease of manufacturing, the end of the mounting base has a U-shaped fixing hole. Screws are passed through the U-shaped fixing hole of the mounting base and the mounting hole on the guide rail to fix the mounting base to the guide rail. However, the fixing positions of the U-shaped fixing holes on multiple mounting bases are different, making it impossible to standardize the installation. This makes the debugging and calibration process cumbersome and affects the assembly efficiency of the fruit and vegetable sorting machine. Utility Model Content

[0005] The present invention aims to provide a fruit cup flipping device, a sorting device, and a fruit and vegetable sorting machine to solve the technical problem that the debugging and calibration process of the mounting base of the fruit cup flipping device on the guide rail is relatively cumbersome in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a fruit cup flipping device, comprising:

[0007] Solenoid valve assembly;

[0008] The mounting base includes a base plate, a first mounting part, and positioning blocks. The solenoid valve assembly is mounted on the base plate. The first mounting part is connected to the base plate. Two positioning blocks are connected to opposite sides of the first mounting part. The distance between the two positioning blocks is far apart from each other along the direction from the base plate to the solenoid valve assembly. The positioning blocks are used to cooperate with the guide rail for installation.

[0009] With the above structure, the two positioning blocks are embedded in the guide rails to achieve the effect of quick positioning and installation of the fruit cup flipping device; the relative position of the positioning block and the base plate in any fruit cup flipping device remains unchanged, which can unify the installation standard, facilitate debugging and calibration, and improve the assembly efficiency of the fruit and vegetable sorting machine.

[0010] In some embodiments, the first mounting portion has a fixing hole located between the two positioning blocks.

[0011] With the above structure, bolts are passed sequentially through the fixing holes and the guide rail to fix the first mounting part to the guide rail. By positioning and installing the positioning block with the guide rail, and then fixing the mounting base and the guide rail with bolts, the fruit cup flipping device can be quickly installed on the guide rail.

[0012] In some embodiments, the fruit cup flipping device further includes a safety module, which is electrically connected to the solenoid valve assembly and connected to the mounting base. The safety module includes a latching part, and the mounting base has a latching groove. The latching part extends into the latching groove to connect the safety module to the mounting base.

[0013] With the above structure, the safety module is electrically connected to the solenoid valve assembly, which can prevent the solenoid valve assembly from burning out in the event of a power failure; in addition, the safety module can be quickly installed on the mounting base through the cooperation of the snap-fit ​​part and the snap-fit ​​slot.

[0014] In some embodiments, the snap-fit ​​groove is formed in the base plate, and the safety module and the solenoid valve assembly are respectively located on opposite sides of the base plate; the mounting base further includes a second mounting part, which is connected to one side of the base plate and extends along the direction from the solenoid valve assembly to the base plate. The second mounting part has a first through hole, through which the wire of the solenoid valve assembly passes.

[0015] With the above structure, the solenoid valve assembly is installed on one side of the base plate, and the wires of the solenoid valve assembly can be passed through the first through hole to be fixed, so as to prevent the wiring from becoming messy.

[0016] In some embodiments, the first mounting portion includes a first connecting plate and a second connecting plate. The first connecting plate is connected to one side of the base plate and extends along the direction from the base plate to the solenoid valve assembly. The first connecting plate has a snap-fit ​​groove, and a strip groove is formed at the junction of the first connecting plate and the base plate. The strip groove is arranged in a horizontal direction. Two snap-fit ​​portions are respectively snapped into one snap-fit ​​groove and one strip groove, and the safety module is installed on the side of the first connecting plate away from the solenoid valve assembly. Two second connecting plates are respectively connected to opposite sides of the first connecting plate, and any one of the second connecting plates extends along the direction from the solenoid valve assembly to the first connecting plate. Each positioning block extends obliquely upward from the upper side of the corresponding second connecting plate.

[0017] With the above structure, the first connecting plate separates the safety module from the solenoid valve assembly to provide sufficient space for the installation of the solenoid valve assembly; in addition, each positioning block extends obliquely upward from the upper side of the corresponding second connecting plate, which increases the distance between the solenoid valve assembly and the fruit cup when the positioning block is installed on the guide rail, so that the length of the striking rod of the solenoid valve assembly can be set longer, which is beneficial to improving the strength of the striking rod of the solenoid valve assembly striking the fruit cup.

[0018] In some embodiments, any of the second connecting plates has a second through hole for arranging the wires of the solenoid valve assembly; the first mounting part further includes a third connecting plate, the third connecting plate is horizontally arranged, the third connecting plate is connected to the side of the first connecting plate away from the base plate, the third connecting plate extends along the direction from the solenoid valve assembly to the first connecting plate, and the third connecting plate has a fixing hole located between the two positioning blocks.

[0019] With the above structure, the wires of the solenoid valve body pass through the second through hole and are connected to the safety module, so that the wire arrangement of the safety module is more compact; the third connecting plate is set horizontally, and the fixing hole is opened on the third connecting plate. This setting makes the structure compact and avoids the third connecting plate from tilting relative to the guide rail after installation.

[0020] In some embodiments, the base plate has a waist-shaped hole, and two sets of waist-shaped holes are spaced apart along the direction from the base plate to the first connecting plate, with one set of waist-shaped holes adjacent to the strip groove; the fruit cup flipping device also includes a fixing member, which passes through the solenoid valve assembly and the waist-shaped hole to install the solenoid valve assembly on the base plate.

[0021] With the above structure, since the first connecting plate and the base plate are an integral structure, the first connecting plate is formed by bending relative to the base plate during the manufacturing process. A set of waist-shaped holes is adjacent to the strip groove, which can prevent the set of waist-shaped holes near the strip groove from deforming during the bending of the first connecting plate relative to the base plate.

[0022] In some embodiments, the mounting base further includes a third mounting portion, the base plate is connected between the first mounting portion and the third mounting portion, and the third mounting portion extends along the base plate to the solenoid valve assembly;

[0023] The solenoid valve assembly includes a solenoid valve body, a striking rod, and a pin. The solenoid valve body is mounted on the base plate. The striking rod includes a striking part and a connecting part. The striking part is connected to the connecting part, and there is a predetermined angle between the striking part and the connecting part. One end of the connecting part away from the striking part is connected to the solenoid valve body. The other end of the striking part away from the connecting part is used to strike the fruit cup. The striking part is located above the mounting base. The pin passes through the striking rod, and the opposite ends of the pin are respectively mounted on the first connecting plate and the third mounting part.

[0024] With the above structure, the two ends of the pin are respectively installed on the first connecting plate and the third mounting part, which can make the vertical distance from the connection point of the connecting part and the solenoid valve body to the pin larger. With the vertical distance from the end of the striking part hitting the fruit cup to the pin unchanged and the output power of the solenoid valve body unchanged, the force of the striking part hitting the end of the fruit cup can be increased, thereby improving the striking intensity of the fruit cup flipping device.

[0025] In some embodiments, the mounting base further includes a third mounting portion, the base plate is connected between the first mounting portion and the third mounting portion, and the third mounting portion extends along the base plate to the solenoid valve assembly;

[0026] The solenoid valve assembly includes a solenoid valve body, a striking rod, and a pin. The solenoid valve body is mounted on the base plate. The striking rod includes a striking part and a connecting part. The striking part is connected to the connecting part, and there is a predetermined angle between the striking part and the connecting part. One end of the connecting part away from the striking part is connected to the solenoid valve body. The other end of the striking part away from the connecting part is used to strike the fruit cup. The striking part is located above the mounting base. The pin includes a first rod part and a second rod part that are perpendicular to each other and connected. The first rod part passes through the striking rod. The end of the first rod part away from the second rod part is mounted on the third mounting part. The end of the second rod part away from the first rod part is mounted on the base plate.

[0027] With the above structure, when installing the solenoid valve assembly on the mounting base, the solenoid valve body can be installed on the base plate, the first rod can be inserted through the striking rod, the end of the first rod away from the second rod can be installed on the third mounting part, and finally the end of the second rod away from the first rod can be installed on the base plate, which can achieve quick installation of the solenoid valve assembly on the mounting base.

[0028] In some embodiments, the solenoid valve assembly further includes a flexible cover mounted on an end of the solenoid valve body and positioned between the solenoid valve body and the striking rod.

[0029] With the above structure, the flexible cover can protect the end of the solenoid valve body, better protect the solenoid valve body, and prevent dust from entering the solenoid valve body.

[0030] In some embodiments, the mounting base is symmetrically arranged along the centerline of the mounting base in a direction perpendicular to the fruit cup conveying direction.

[0031] With the above structure, when it is necessary to drop the fruits and vegetables on the fruit cup to the other side of the guide rail, the fruit cup flipping device can be installed on the other side of the guide rail, and the solenoid valve assembly can be rotated 180 degrees relative to the mounting base and installed on the mounting base.

[0032] This utility model also provides a sorting device, including the fruit cup flipping device in any of the above embodiments. The sorting device further includes a driving component, a conveying chain, and a guide rail.

[0048] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0049] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a fruit cup flipping device provided in one embodiment of this utility model; Figure 2 yes Figure 1 A schematic diagram of the structure of the fruit cup flipping device installed on the guide rail.

[0050] An embodiment of this utility model provides a fruit cup flipping device 100, which includes a solenoid valve assembly 10 and a mounting base 20. The mounting base 20 includes a base plate 21, a first mounting part 22, and positioning blocks 23. The solenoid valve assembly 10 is mounted on the base plate 21, the first mounting part 22 is connected to the base plate 21, and two positioning blocks 23 are provided. The two positioning blocks 23 are connected to opposite sides of the first mounting part 22, and the distance between the two positioning blocks 23 is far away from each other along the direction from the base plate 21 to the solenoid valve assembly 10. The positioning blocks 23 are used to cooperate with the guide rail 110 for installation.

[0051] It should be noted that multiple fruit cups are placed on a conveyor chain 120, which is placed on a guide rail 110. The conveyor chain 120 is driven by a drive component to move the multiple fruit cups along the length of the guide rail 110. When the fruit cups move to the fruit cup flipping device 100, the fruit cup flipping device 100 can drive the fruit cups to flip, so that the fruits and vegetables on the fruit cups fall out of the fruit cups.

[0052] Specifically, the base plate 21 is placed horizontally, the solenoid valve assembly 10 is mounted on the base plate 21, the first mounting part 22 is located below the guide rail 110, and the positioning block 23 is engaged with the guide rail 110. The base plate 21, the first mounting part 22, and the positioning block 23 are an integrated structure, and the positioning block 23 is bent along the direction from the base plate 21 to the solenoid valve assembly 10. The bending angle can be 30°, 40°, or 45°, etc., preferably 30°.

[0053] In the specific implementation process, the bottom of the guide rail 110 is provided with an installation groove 112, and two positioning blocks 23 are respectively embedded in the installation groove 112 to achieve the effect of quickly positioning and installing the fruit cup flipping device 100 on the guide rail 110. Moreover, the relative position of the positioning block 23 and the base plate 21 in any fruit cup flipping device 100 remains unchanged, which can unify the installation standard, facilitate debugging and calibration, and improve the assembly efficiency of the fruit and vegetable sorting machine.

[0054] In this embodiment, the first mounting part 22 is a plate-shaped structure and is horizontally arranged.

[0055] See Figure 3 , Figure 3 yes Figure 1 A schematic diagram of the mounting base.

[0056] In one embodiment, the mounting base 20 is symmetrically arranged along the center line L of the mounting base 20 in a direction perpendicular to the fruit cup conveying direction.

[0057] Specifically, the fruit cup flipping device 100 drives the fruit cup to flip in one direction so that the fruit and vegetables on the fruit cup fall from the fruit cup to one side of the guide rail 110; if it is necessary to drop the fruit and vegetables on the fruit cup to the other side of the guide rail 110, the fruit cup flipping device 100 needs to be installed on the other side of the guide rail 110, and the solenoid valve assembly 10 is rotated 180 degrees relative to the base plate 21 and installed on the base plate 21.

[0058] In one embodiment, the first mounting part 22 has a fixing hole 221, which is located between two positioning blocks 23.

[0059] Specifically, the fixing hole 221 is used for screws or bolts to fix the fruit cup flipping device 100 to the guide rail 110. In actual operation, the guide rail 110 has a threaded hole corresponding to the fixing hole 221. Screws are passed through the fixing hole 221 and the threaded hole in sequence to fix the first mounting part 22 to the guide rail 110. By positioning and installing the positioning block 23 with the guide rail 110, and then fixing the mounting base 20 and the guide rail 110 with screws, the effect of quickly installing the fruit cup flipping device 100 onto the guide rail 110 can be achieved.

[0060] In this embodiment, the fixing hole 221 is located in the middle of the line connecting the two positioning blocks 23, so that after the mounting base 20 is fixed, the forces on both sides of the mounting base 20 are balanced, and the mounting base 20 is prevented from tilting relative to the guide rail 110 after installation.

[0061] See Figure 1 and Figure 4 , Figure 4 yes Figure 1 A schematic diagram of the exploded structure of the fruit cup flipping device.

[0062] In one embodiment, the fruit cup flipping device 100 further includes a safety module 30, which is electrically connected to the solenoid valve assembly 10 and connected to the mounting base 20. The safety module 30 includes a latching part 31, and the mounting base 20 has a latching groove 24. The latching part 31 extends into the latching groove 24 to connect the safety module 30 to the mounting base 20.

[0063] See Figure 4 and Figure 5 , Figure 5 yes Figure 4 A schematic diagram of the structure of the insurance module.

[0064] Specifically, the safety module 30 is electrically connected to the solenoid valve assembly 10 to prevent the solenoid valve assembly 10 from burning out in the event of a power failure. The latching part 31 extends into the latching groove 24 to quickly install the safety module 30 onto the mounting base 20. Two latching parts 31 are provided, extending upwards from the end of the safety module 30 and spaced apart. Each latching part 31 includes an extension section 311 and a bent section 312, which are perpendicular to each other. The bent sections 312 of the two latching parts 31 extend relative to each other, and the end of the bent section 312 facing away from the extension section 311 has a slope, which serves as a guide.

[0065] During actual installation, the latching part 31 is aligned with the latching groove 24. When the inclined surface abuts against the groove wall of the latching groove 24, the distance between the two latching parts 31 increases. As the extension section 311 continues to extend into the latching groove 24, the inclined surface extends into the side of the mounting base 20 away from the safety module 30, and the bent section 312 abuts against the side of the mounting base 20 away from the safety module 30, thus completing the installation of the safety module 30. The purpose of this design is to allow for quick and secure installation of the safety module 30 onto the base plate 21.

[0066] See also Figure 1 and Figure 3In one embodiment, the snap-fit ​​groove 24 is formed in the base plate 21, and the safety module 30 and the solenoid valve assembly 10 are respectively located on opposite sides of the base plate 21; the mounting base 20 also includes a second mounting part 25, which is connected to one side of the base plate 21. The second mounting part 25 extends along the direction from the solenoid valve assembly 10 to the base plate 21, and the second mounting part 25 has a first through hole 251 through which the wire of the solenoid valve assembly 10 passes.

[0067] Specifically, the second mounting part 25 has a plate-like structure, and the second mounting part 25 and the base plate 21 are an integrated structure. The solenoid valve assembly 10 is mounted on one side of the base plate 21. In the actual wiring layout, the wires of the solenoid valve assembly 10 can be connected to the connector, and then the connector is fixed to the first through hole 251 to prevent the wires from becoming tangled. In addition, the connector can achieve quick connection to an external power source. By mounting the fuse module 30 and the solenoid valve assembly 10 on opposite sides of the base plate 21, interference between the wire arrangement of the fuse module 30 and the wire arrangement of the solenoid valve assembly 10 can be avoided.

[0068] See also Figure 1 and Figure 4 The mounting base 20 also includes a third mounting part 26. The base plate 21 is connected between the first mounting part 22 and the third mounting part 26. The third mounting part 26 extends along the base plate 21 to the solenoid valve assembly 10. The solenoid valve assembly 10 includes a solenoid valve body 11, a striking rod 12, and a pin 13. The solenoid valve body 11 is mounted on the base plate 21. The striking rod 12 includes a striking part 121 and a connecting part 122. The striking part 121 is connected to the connecting part 122, and there is a predetermined angle between the striking part 121 and the connecting part 122. One end of the connecting part 122 away from the striking part 121 is connected to the solenoid valve body 11. The end of the striking part 121 away from the connecting part 122 is used to strike the fruit cup. The striking part 121 is located above the mounting base 20. The pin 13 includes a first rod part 131 and a second rod part 132 that are perpendicular to each other and connected. The first rod part 131 passes through the striking rod 12. The end of the first rod part 131 away from the second rod part 132 is mounted on the third mounting part 26. The end of the second rod part 132 away from the first rod part 131 is mounted on the base plate 21.

[0069] When installing the solenoid valve assembly 10 on the mounting base 20, the solenoid valve body 11 can be installed on the base plate 21, the first rod 131 can be inserted through the striking rod 12, the end of the first rod 131 away from the second rod 132 can be installed on the third mounting part 26, and finally the end of the second rod 132 away from the first rod 131 can be installed on the base plate 21, so that the solenoid valve assembly 10 can be quickly installed on the mounting base 20.

[0070] Specifically, the third mounting portion 26 and the first mounting portion 22 are located on opposite sides of the solenoid valve assembly 10 to provide protection for the solenoid valve assembly 10. The third mounting portion 26 includes two upright plates 261, which are horizontally spaced apart on one side of the base plate 21. There is a gap between the two upright plates 261 to facilitate heat dissipation of the solenoid valve assembly 10. The end of the first rod portion 131 away from the second rod portion 132 is mounted on a corresponding upright plate 261. The pin 13 can be formed by bending a metal rod.

[0071] See Figure 6 , Figure 7 and Figure 8 , Figure 6 This is a schematic diagram of the structure of a fruit cup flipping device provided in another embodiment of this utility model; Figure 7 yes Figure 6 An exploded view of the fruit cup flipping device according to another embodiment; Figure 8 yes Figure 6 A top view of the mounting base in another embodiment of the fruit cup flipping device.

[0072] In another embodiment, the first mounting part 22 includes a first connecting plate 222 and a second connecting plate 223. The first connecting plate 222 is connected to one side of the base plate 21 and extends along the direction from the base plate 21 to the solenoid valve assembly 10. The first connecting plate 222 has a snap-fit ​​groove 24 and a strip groove 2221 at the junction of the first connecting plate 222 and the base plate 21. The strip groove 2221 is arranged in a horizontal direction. Two snap-fit ​​parts 31 are respectively snapped into a snap-fit ​​groove 24 and a strip groove 2221 to install the safety module 30 on the side of the first connecting plate 222 away from the solenoid valve assembly 10. Two second connecting plates 223 are respectively connected to the opposite sides of the first connecting plate 222. Any second connecting plate 223 extends along the direction from the solenoid valve assembly 10 to the first connecting plate 222. Each positioning block 23 extends obliquely upward from the upper side of the corresponding second connecting plate 223.

[0073] Specifically, the two latching parts 31 of the safety module 30 are respectively installed in the latching groove 24 and the strip groove 2221. The safety module 30 is located on the side of the first connecting plate 222 away from the solenoid valve assembly 10. The first connecting plate 222 separates the safety module 30 from the solenoid valve assembly 10 to provide sufficient space for the solenoid valve assembly 10 to be installed. The second connecting plate 223 is connected to one side of the first connecting plate 222 along one side of the vertical direction. The second connecting plate 223 extends along the direction from the solenoid valve assembly 10 to the first connecting plate 222. Each positioning block 23 extends obliquely upward from the upper side of the corresponding second connecting plate 223. The oblique upward extension of each positioning block 23 from the upper side of the corresponding second connecting plate 223 increases the distance between the solenoid valve assembly 10 and the fruit cup when the positioning block 23 is installed on the guide rail 110, so that the length of the striking rod of the solenoid valve assembly 10 can be set longer, which is beneficial to improving the strength of the striking rod of the solenoid valve assembly 10 striking the fruit cup.

[0074] In another embodiment, any second connecting plate 223 has a second through hole 2231 for arranging the wires of the solenoid valve assembly 10; the first mounting part 22 also includes a third connecting plate 224, which is horizontally arranged and connected to the side of the first connecting plate 222 away from the bottom plate 21. The third connecting plate 224 extends along the direction from the solenoid valve assembly 10 to the first connecting plate 222, and a fixing hole 221 is formed on the third connecting plate 224. The third connecting plate 224 is located between two positioning blocks 23.

[0075] Specifically, the wires of the solenoid valve body 11 pass through the second through hole 2231 and are connected to the safety module 30 to achieve a compact structure. The third connecting plate 224 and the first connecting plate 222 are an integrated structure. The third connecting plate 224 is horizontally positioned, and the fixing hole 221 is formed on the third connecting plate 224. This arrangement makes the structure compact and prevents the third connecting plate 224 from tilting relative to the guide rail 110 after installation. In actual installation, the third connecting plate 224 is fixed to the guide rail 110 using a single screw or bolt.

[0076] In another embodiment, the base plate 21 has a waist-shaped hole 211, and two sets of waist-shaped holes 211 are spaced apart along the direction from the base plate 21 to the first connecting plate 222. One set of waist-shaped holes 211 is adjacent to the strip groove 2221. The fruit cup flipping device 100 also includes a fixing member 16, which passes through the solenoid valve assembly 10 and the waist-shaped hole 211 to install the solenoid valve assembly 10 on the base plate 21.

[0077] Specifically, a set of oblong holes 211 includes two oblong holes 211. The solenoid valve assembly 10 includes a base 14, with the four corners of the base 14 mounted on the base plate 21 via four oblong holes 211. The base 14 supports the solenoid valve body 11. Two oblong holes 211 are adjacent to the slot 2221. This arrangement is because, since the first connecting plate 222 and the base plate 21 are an integrated structure, the first connecting plate 222 is bent relative to the base plate 21 during manufacturing. If the slot 2221 were not provided, the oblong holes 211 adjacent to the slot 2221 would easily deform when the first connecting plate 222 is bent, preventing the base 14 from being mounted on the base plate 21. The fastener 16 may include bolts and nuts. After the bolt passes through the base 14 and the oblong holes 211, the nut is fitted onto the bolt, fixing the base 14 and the base plate 21 together.

[0078] In another embodiment, the mounting base 20 further includes a third mounting portion 26, with the base plate 21 connected between the first mounting portion 22 and the third mounting portion 26. The third mounting portion 26 extends along the base plate 21 toward the solenoid valve assembly 10. A pin 13 passes through the striking rod 12, with its opposite ends mounted on the first connecting plate 222 and the third mounting portion 26, respectively.

[0079] Specifically, the third mounting part 26 and the first connecting plate 222 are located on opposite sides of the solenoid valve assembly 10 to provide protection for the solenoid valve assembly 10. The third mounting part 26 includes two upright plates 261, which are horizontally spaced on one side of the base plate 21. There is a gap between the two upright plates 261 to facilitate heat dissipation of the solenoid valve assembly 10. The pin 13 is horizontally arranged, and its two ends are respectively mounted on the first connecting plate 222 and the upright plate 261 for easy installation, fixing, and adjustment. The connecting shaft 114 of the solenoid valve body 11 passes through the guide groove 1120 of the connecting part 122. When the reciprocating motion of the solenoid valve core 116 of the solenoid valve body 11 drives the striking rod 12 to rotate relative to the pin 13, the connecting shaft 114 can move along the guide groove 1120.

[0080] The two ends of the pin 13 are respectively mounted on the first connecting plate 222 and the third mounting part 26, which can make the vertical distance from the connecting shaft 114 of the connecting part 122 and the solenoid valve body 11 to the pin 13 larger. When the vertical distance from the end of the fruit cup struck by the striking part 121 to the pin 13 remains unchanged and the output power of the solenoid valve body 11 remains unchanged, the force of the striking part 121 striking the end of the fruit cup can be increased, thereby improving the striking intensity of the fruit cup flipping device 100.

[0081] In this embodiment, the width of the connecting portion 122 gradually increases in the direction away from the striking portion 121 to improve the strength of the connecting portion 122. In this embodiment, the distance between the pin 13 and the connecting shaft 114 of the solenoid valve body 11 is 9.4 mm.

[0082] See Figure 7 In another embodiment, the solenoid valve assembly 10 further includes a flexible cover 15, which is mounted on the end of the solenoid valve body 11 and is located between the solenoid valve body 11 and the striking rod 12.

[0083] Specifically, the flexible cover 15 can protect the end of the solenoid valve body 11, better protect the solenoid valve body 11, and prevent dust from entering the solenoid valve body 11.

The driving component is used to drive the conveying chain 120 to move the fruit cup along the guide rail 110. The guide rail 110 has an installation groove 112, and two positioning blocks 23 are installed in the installation groove 112.

The fruit and vegetable sorting machine also includes a feeding device, a transport device, a detection device, and a sorting device 200.

[0087] The feeding device includes a hopper and a feeding belt. Fruits and vegetables are placed in the hopper, and the hopper discharges the fruit and vegetables onto the feeding belt. The feeding belt then transports the fruit and vegetables to the transport device.

[0088] The transport device serves to transport fruits and vegetables, transferring them to the testing device.

[0089] The testing device examines fruits and vegetables, such as detecting damage to their skin and their weight, in order to grade them accordingly.
