Description

Technical Field

[0001] The invention belongs to the field of edible fungus packaging, in particular to a green packaging structure for edible fungi. Background Art

[0002] Edible fungi refer to mushrooms (large fungi) with large fruiting bodies that are edible. They are commonly known as mushrooms. Common edible fungi include shiitake mushrooms, straw mushrooms, etc. China is rich in edible fungi resources and is one of the earliest countries to cultivate and utilize edible fungi. With the development of the times, edible fungi have entered the homes of people across the country.

[0003] In order to allow edible fungi to be picked and purchased by people, the processed edible fungi need to be packaged and sealed after picking to reduce water loss in the edible fungi and pollution from the external environment, thereby extending the edible time of the edible fungi.

[0004] When edible fungi are sold, they need to be placed in packaging boxes and sealed with plastic wrap to reduce the water loss rate of the finished edible fungi, which is conducive to subsequent sales. During the packaging stage, an appropriate amount of edible fungi needs to be placed in the packaging box, neither too little nor overflowing the box. Higher packaging requirements also require that the quality and size of the edible fungi in the same box are similar. Such delicate work is difficult to replace with machines.

[0005] To this end, the present invention provides a green packaging structure for edible fungi. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the green packaging structure for edible fungi of the present invention comprises a horizontally placed screw nut mechanism, the movable end of the screw nut mechanism is connected to four selection trays, two groups of feeding buckets for feeding are arranged above the selection trays, a conveyor belt is arranged on the side of the selection tray away from the feeding buckets, a plurality of packaging boxes are placed on the surface of the conveyor belt, a selection component is arranged between the selection tray and the conveyor belt, and the selection component is used to transfer the edible fungi in the selection tray to the packaging boxes one by one according to the standard;

[0008] By setting up the picking tray, an appropriate amount of edible fungi is put into the four picking trays of the feeding bucket box, and the picking tray is driven to move to the bottom of the picking component through the screw nut mechanism. The picking component will extend into the picking tray, and the edible fungi of the same specifications will be selected outward one by one, and transferred to the packaging box on the conveyor belt. After the preset time is over, the packaging box is full of edible fungi. At this time, the conveyor belt moves forward and a new batch of packaging boxes are replaced to repeat the above work. Through this setting, edible fungi of different specifications can be stacked one by one and stably in the packaging box among a large number of scattered edible fungi, which greatly reduces the time required to put the edible fungi into the packaging box in the packaging process.

[0009] Preferably, the picking component includes three adsorption rollers, the surface of the adsorption roller is connected to a plurality of suction cups, both sides of the adsorption roller are rotatably connected with a transmission tube, one end of the transmission tube is fixedly connected to a negative pressure pump, a driving shaft is fixedly connected between the two negative pressure pumps, one side of the driving shaft is connected to a reduction motor, the outer side of the reduction motor is connected to a support platform for support, a transfer component is arranged on the outer side of the adsorption roller, the transfer component is used to transfer the adsorbed edible fungi and to drive the adsorption roller to rotate, and the drive shaft is driven to rotate by the reduction motor, so that the adsorption roller and the transmission tube which were originally in a horizontal state are rotated It is transferred into the selection plate and turned on by the negative pressure pump. The negative pressure is evenly transmitted to the suction cup through the transmission tube. The suction force of the suction cup can be controlled by adjusting the output of the negative pressure pump, so as to adsorb edible fungi of different sizes. The transfer component first drives the adsorption roller to rotate counterclockwise. During the rotation, the surface of the adsorption roller will contact the edible fungi, and the edible fungi will be adsorbed on the surface of the suction cup. When it moves to the top, it is transferred through the transfer component. The selection method is to first select the edible fungi with smaller volume and mass, and then adsorb the edible fungi with larger volume and mass, thereby achieving the effect of selecting edible fungi of the same specification into the same packaging box.

[0010] Preferably, the middle part of the adsorption roller is connected to the transmission tube, a negative pressure tube is connected between the middle part of the adsorption roller and the suction cup, a plurality of side tubes are connected between the middle part of the negative pressure tube and the suction cup, a metal ball is slidably connected to the middle part of the negative pressure tube, and a blocking rod is connected to the bottom of the negative pressure tube. When the suction cup absorbs the edible fungi and rotates to the top of the adsorption roller, the metal ball will fall under the action of gravity and be blocked by the blocking rod. The centrifugal force generated by the rotation is not enough to overcome the weight of the metal ball. At this time, since the suction cannot pass through the side tubes in large quantities, the edible fungi above can be easily transferred away by the transfer assembly. As the adsorption roller continues to rotate, when the metal ball crosses the horizontal line, under the action of inertia and gravity, the metal ball will move to the position of the suction cup, allowing the suction to pass through the side tubes and normally absorb the edible fungi. The metal ball has a large mass and its own gravity is sufficient to get rid of the suction.

[0011] Preferably, the transfer assembly includes two drive motors one, and the output end of the drive motor one is fixedly connected to an active disk. The two active disks are movably fitted with the outer surface of the adsorption roller. The drive motor one drives the active disk to rotate, and then drives the adsorption roller to rotate, thereby achieving the effect of the adsorption roller continuously adsorbing edible fungi, and at the same time the two active disks do not contact the suction cup.

[0012] Preferably, the transfer assembly also includes a plurality of belts, two support columns are arranged between the selection disk and the conveyor belt, a transmission rod is connected between the two support columns, a driving motor 2 is arranged on the inner side of one of the support columns, the output end of the driving motor 2 is connected to the transmission rod, a groove for limiting the deviation of the belt is provided on the surface of the transmission rod, a restraining rod is rotatably connected between the two active disks, the restraining rod does not rotate with the active disk, the belt is sleeved between the transmission rod and the restraining rod, when the suction cup adsorbs the edible fungi and transfers them upward to the top, the suction force is greatly reduced at this time, and as the adsorption roller continues to move, the suction force is greatly reduced. Continuing to rotate counterclockwise will move the edible fungi to the surface of the belt. The belt also rotates counterclockwise under the drive of the second driving motor. With the friction of the belt, the edible fungi can be transferred to the top of the belt. Since the positions of the transmission rod and the supporting column are always fixed, the edible fungi transported backwards will eventually be transported to the top of the positioned packaging box and fall into it. Through this setting, the same specification of edible fungi can be screened and sent into the packaging box one by one. After the preset time of transportation, another batch of packaging boxes can be replaced. If more precise filling of edible fungi is required, optical equipment can be added to one side of the conveyor belt for real-time observation.

[0013] Preferably, a guide plate is connected between the surfaces of the two negative pressure pumps, and the guide plate is located between the belts. The cross-section of the belt is arranged in a raised shape on both sides, and a plurality of elastic protrusions are fixed to the surface of the belt. The guide plate is arranged to ensure that the belt can maintain a relatively stable shape when the adsorption roller rotates to adjust the angle, and will not affect the operation of other parts. The structural arrangement of the belt can well protect the edible fungi from falling to both sides, and the protrusions on the surface can increase friction, so that the edible fungi can be transported normally in the direction of the conveyor belt.

[0014] Preferably, a sorting machine is provided at the end of the conveyor belt, and a plurality of binding frame grooves for placing packaging boxes are fixedly connected to the surface of the conveyor belt. Three adsorption rollers can work simultaneously to select edible fungi in different picking plates. Since the suction forces of the three adsorption rollers may be different, the three portions of edible fungi can be transported in different directions when they are moved to the sorting machine.

[0015] Preferably, the packaging box is made of a degradable hard material, and the four corners of the top of the packaging box are fixed with arc-shaped pressure strips, and the pressure strips are made of elastic material. During the process of putting edible fungi into the packaging box, the height of the belt is basically level with the packaging box, and no large kinetic energy will be generated. At the same time, the edible fungi bouncing into the packaging box will be blocked by the pressure strips to prevent the edible fungi from popping out of the packaging box.

[0016] Preferably, an upper crotch guard is fixedly connected to the top of the selection plate on one side close to the feeding bucket, and a series table is fixedly connected to the bottom of the selection plate. The four series tables are fixedly connected to each other and to the moving end of the screw nut mechanism. The upper crotch guard is provided to reduce the problem that the edible fungi are not completely adsorbed and are thrown out of the selection plate by inertia during the rotation of the adsorption roller. The series table is provided to allow the four selection plates to move simultaneously to reduce the difficulty of control.

[0017] Preferably, a sliding ball is provided at the bottom of the picking plate, a cross bar is fixedly connected to the bottom of the picking plate, the middle part of the picking plate is slidably connected to the cross bar, a flexible undulating pad is fixedly connected to the bottom of the picking plate, and the undulating pad is located above the sliding ball. During the adsorption process of the adsorption roller, the four picking plates are controlled to sway slightly horizontally through the screw nut mechanism, so that the sliding ball shakes continuously inside, thereby hitting the undulating pad to swing, and the edible fungi at the bottom can be rolled upward, so that the edible fungi inside can be more evenly selected by the suction force. After each selection period, new edible fungi are put into the picking plate through two sets of feeding buckets.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The green packaging structure for edible fungi described in the present invention, through the setting of the picking tray, uses the feeding bucket box to put an appropriate amount of edible fungi into the four picking trays. It should be noted that: the edible fungi commonly used in this device are white mushrooms, and the picking tray is driven by the screw nut mechanism to move to the bottom of the picking component, and the picking component will extend into the picking tray, and the edible fungi of the same specifications will be selected outward one by one, and transferred to the packaging box on the conveyor belt. After the predetermined time is over, the packaging box is full of edible fungi. At this time, the conveyor belt moves forward and a new batch of packaging boxes are replaced to repeat the above work. Through this setting, it is achieved that edible fungi of different specifications can be stacked one by one and stably into the packaging box among a large number of scattered edible fungi, which greatly reduces the time required for putting the edible fungi into the packaging box in the packaging process.

[0020] 2. The green packaging structure for edible fungi described in the present invention drives the driving shaft to rotate through a reduction motor, so that the originally horizontal adsorption roller and transmission tube are rotated and sent into the selection plate. The negative pressure pump is turned on, and the negative pressure is evenly transmitted to the suction cup through the transmission tube. The suction force of the suction cup can be controlled by adjusting the output of the negative pressure pump, so as to adsorb edible fungi of different sizes. The transfer component first drives the adsorption roller to rotate counterclockwise. During the rotation, the surface of the adsorption roller will contact the edible fungi, and the edible fungi will be adsorbed on the surface of the suction cup. When it moves to the top, it is transferred through the transfer component. The selection method is to first select the edible fungi with smaller volume and mass, and then adsorb the edible fungi with larger volume and mass, thereby achieving the effect of selecting edible fungi of the same specification to enter the same packaging box.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figure 1 to Figure 2 As shown, a green packaging structure for edible fungi according to an embodiment of the present invention comprises a horizontally placed lead screw nut mechanism 1, the movable end of the lead screw nut mechanism 1 is connected with four selection trays 6, two groups of feeding buckets 2 for feeding are arranged above the selection trays 6, a conveyor belt 3 is arranged on the side of the selection tray 6 away from the feeding buckets 2, a plurality of packaging boxes 4 are placed on the surface of the conveyor belt 3, a selection component is arranged between the selection tray 6 and the conveyor belt 3, and the selection component is used to transfer the edible fungi in the selection tray 6 to the packaging boxes 4 one by one according to the standard;

[0032] During operation, when selling edible fungi, they need to be placed in a packaging box 4, and then sealed with a plastic wrap to reduce the water loss rate of the finished edible fungi, which is beneficial to subsequent sales. In the packaging stage, an appropriate amount of edible fungi needs to be placed in the packaging box 4, which should not be too little or overflow from the packaging box. For packaging with higher requirements, the quality and size of the edible fungi in the same packaging box 4 should be similar. Such delicate work is difficult to be replaced by machinery, which makes this process the most time-consuming part of the entire packaging process.

[0033] By setting the picking tray 6, a proper amount of edible fungi are put into the four picking trays 6 using the feeding bucket 2. It should be noted that the edible fungi commonly used in this device are white mushrooms. The picking tray 6 is driven by the screw nut mechanism 1 to move to the bottom of the picking component, and the picking component will extend into the picking tray 6 to select the edible fungi of uniform specifications one by one and transfer them to the packaging box 4 on the conveyor belt 3. After the predetermined time is over, the packaging box 4 is full of edible fungi. At this time, the conveyor belt 3 moves forward and a new batch of packaging boxes 4 are replaced to repeat the above work. Through this setting, it is possible to stack edible fungi of different specifications into the packaging box 4 one by one and stably among a large number of scattered edible fungi, which greatly reduces the time required for the edible fungi to be placed in the packaging box 4 during the packaging process.

[0034] like Figures 1 to 6 As shown, the picking assembly includes three adsorption rollers 7, the surface of the adsorption roller 7 is connected with a plurality of suction cups 20, both sides of the adsorption roller 7 are rotatably clamped with a transmission tube 19, one end of the transmission tube 19 is fixedly connected with a negative pressure pump 18, a driving shaft is fixedly connected between the two negative pressure pumps 18, one side of the driving shaft is connected with a reduction motor 14, the outer side of the reduction motor 14 is connected with a support platform 8 for support, and the outer side of the adsorption roller 7 is provided with a transfer assembly, the transfer assembly is used to transfer the adsorbed edible fungi, and is used to drive the adsorption roller 7 to rotate;

[0035] During operation, the drive shaft is driven to rotate by the reduction motor 14, so that the originally horizontal adsorption roller 7 and the transmission tube 19 are rotated and sent into the selection plate 6, and the negative pressure pump 18 is turned on, and the negative pressure is evenly transmitted to the suction cup 20 through the transmission tube 19. The suction force of the suction cup 20 can be controlled by adjusting the output of the negative pressure pump 18, so as to adsorb edible fungi of different sizes. The transfer component first drives the adsorption roller 7 to rotate counterclockwise. During the rotation, the surface of the adsorption roller 7 will contact the edible fungi, and the edible fungi will be adsorbed on the surface of the suction cup 20. When it moves to the top, it is transferred by the transfer component. The selection method is to first select the edible fungi with smaller volume and mass, and then adsorb the edible fungi with larger volume and mass, thereby achieving the effect of selecting edible fungi of the same specification into the same packaging box 4.

[0036] like Figures 4 to 6 As shown, the middle part of the adsorption roller 7 is connected to the transmission pipe 19, a negative pressure pipe 22 is connected between the middle part of the adsorption roller 7 and the suction cup 20, a plurality of side pipes 23 are connected between the middle part of the negative pressure pipe 22 and the suction cup 20, a metal ball 24 is slidably connected to the middle part of the negative pressure pipe 22, and a blocking rod is connected to the bottom of the negative pressure pipe 22;

[0037] During operation, when the suction cup 20 sucks the edible fungi and rotates to the top of the suction roller 7, the metal ball 24 will fall under the action of gravity and be blocked by the blocking rod. The centrifugal force generated by the rotation is not enough to overcome the weight of the metal ball 24. At this time, since the suction force cannot pass through the side tube 23 in large quantities, the edible fungi above can be easily transferred away by the transfer component. As the suction roller 7 continues to rotate, when the metal ball 24 crosses the horizontal line, under the action of inertia and gravity, the metal ball 24 will move to the position of the suction cup 20, allowing the suction force to pass through the side tube 23 and normally adsorb the edible fungi. The metal ball 24 has a large mass and its own gravity is sufficient to get rid of the suction force.

[0038] like Figure 3 to Figure 4 As shown, the transfer assembly includes two drive motors 16, the output end of the drive motor 16 is fixedly connected to an active disk 17, and the two active disks 17 are movably fitted with the outer surface of the adsorption roller 7;

[0039] During operation, the driving motor 16 drives the active disk 17 to rotate, thereby driving the adsorption roller 7 to rotate, so that the adsorption roller 7 continuously adsorbs the edible fungi, and at the same time, the two active disks 17 do not contact the suction cup 20.

[0040] like Figures 2 to 4As shown, the transfer assembly also includes a plurality of belts 13, two support columns 11 are arranged between the selection disk 6 and the conveyor belt 3, a transmission rod 12 is connected between the two support columns 11, a second driving motor is arranged on the inner side of one of the support columns 11, the output end of the second driving motor is connected to the transmission rod 12, a groove for limiting the deviation of the belt 13 is provided on the surface of the transmission rod 12, a restraining rod is rotatably connected between the two active disks 17, the restraining rod does not rotate with the active disk 17, and the belt 13 is sleeved between the transmission rod 12 and the restraining rod;

[0041] During operation, when the suction cup 20 absorbs the edible fungi and transfers them upward to the top, the suction force is greatly reduced. As the adsorption roller 7 continues to rotate counterclockwise, the edible fungi are moved to the surface of the belt 13. The belt 13 also rotates counterclockwise under the drive of the driving motor 2. With the friction of the belt 13, the edible fungi can be transferred to the top of the belt 13. Since the positions of the transmission rod 12 and the support column 11 are always fixed, the edible fungi transported backward will eventually be transported to the top of the positioned packaging box 4 and fall into it. Through this arrangement, the edible fungi of the same specifications are screened and sent into the packaging box 4 one by one. After the predetermined time of transportation, another batch of packaging boxes 4 are replaced. If more accurate filling of edible fungi is required, optical equipment can be added to one side of the conveyor belt 3 for real-time observation.

[0042] like Figures 2 to 4 As shown, a guide plate 15 is connected between the surfaces of the two negative pressure pumps 18, and the guide plate 15 is located between the belts 13. The cross section of the belts 13 is arranged in a warped shape on both sides, and the surface of the belts 13 is also fixed with a plurality of elastic protrusions;

[0043] During operation, the guide plate 15 is set to ensure that when the adsorption roller 7 rotates to adjust the angle, the belt 13 can also maintain a relatively stable shape and will not affect the operation of other parts. The structural setting of the belt 13 can well protect the edible fungi from falling to both sides, and the protrusions on the surface can increase the friction, so that the edible fungi can be transported normally in the direction of the conveyor belt 3.

[0044] like Figure 1 to Figure 2 As shown, a sorting machine 5 is provided at the end of the conveyor belt 3, and a plurality of binding frame grooves for placing packaging boxes 4 are fixedly connected to the surface of the conveyor belt 3. Three adsorption rollers 7 can work simultaneously to select edible fungi in different selection trays 6. Since the suction forces set by the three adsorption rollers 7 may be different, the three portions of edible fungi can be transported in different directions when they are moved to the sorting machine 5.

[0045] like Figure 5As shown, the packaging box 4 is made of a degradable hard material, and the four corners of the top of the packaging box 4 are fixedly connected with arc-shaped pressure strips 21, and the pressure strips 21 are made of elastic material. When working, when the edible fungi are put into the packaging box 4, the height of the belt 13 is basically level with the packaging box 4, and no large kinetic energy will be generated. At the same time, the edible fungi bouncing into the packaging box 4 will be blocked by the pressure strips 21 to prevent the edible fungi from popping out of the packaging box 4.

[0046] like Figures 2 to 4 As shown, an upper crotch guard 9 is fixedly connected to the top of the selection plate 6 on one side of the feeding bucket 2, and a series table 10 is fixedly connected to the bottom of the selection plate 6. The four series tables 10 are fixedly connected to each other and to the moving end of the screw nut mechanism 1. When working, the upper crotch guard 9 is set to reduce the problem that the edible fungi are not completely adsorbed during the rotation of the adsorption roller 7 and are thrown out of the selection plate 6 by inertia. The series table 10 allows the four selection plates 6 to move simultaneously to reduce the control difficulty.

[0047] like Figure 6 As shown, a sliding ball 25 is provided at the bottom of the selection tray 6, a cross bar is fixedly connected to the bottom of the selection tray 6, the middle of the selection tray 6 is slidably connected to the cross bar, and a flexible undulating pad 26 is fixedly connected to the bottom of the selection tray 6, and the undulating pad 26 is located above the sliding ball 25;

[0048] During operation, during the adsorption process of the adsorption roller 7, the four picking plates 6 are controlled to swing slightly horizontally through the screw nut mechanism 1, so that the sliding ball 25 is constantly shaking inside, thereby hitting the undulating pad 26 to swing, and the edible fungi at the bottom can be rolled upward, so that the edible fungi inside can be more evenly selected by the suction force. After each selection period, new edible fungi are put into the picking plate 6 through two sets of feeding buckets 2.

[0049] When working, through the setting of the selection plate 6, a proper amount of edible fungi is put into the four selection plates 6 using the feeding bucket 2. It should be noted that the edible fungi commonly used in this device are white mushrooms. The selection plate 6 is driven by the screw nut mechanism 1 to move to the bottom of the selection component, and the selection component will extend into the selection plate 6, and the edible fungi of uniform specifications will be selected one by one outwards and transferred to the packaging box 4 of the conveyor belt 3. After the predetermined time is over, the packaging box 4 is full of edible fungi. At this time, the conveyor belt 3 moves forward, and a new batch of packaging boxes 4 are replaced to repeat the above work. Through this setting, it is achieved that edible fungi of different specifications are stacked one by one and stably in the packaging box 4 among a large number of scattered edible fungi, which greatly reduces the time required for the edible fungi to be put into the packaging box 4 in the packaging process;

[0050] The drive shaft is driven to rotate by the reduction motor 14, so that the originally horizontal suction roller 7 and the transmission tube 19 are rotated and sent into the selection plate 6. The negative pressure pump 18 is turned on, and the negative pressure is evenly transmitted to the suction cup 20 through the transmission tube 19. The suction force of the suction cup 20 can be controlled by adjusting the output of the negative pressure pump 18, so as to adsorb edible fungi of different sizes. The transfer component first drives the suction roller 7 to rotate counterclockwise. The surface of the suction roller 7 during the rotation will contact the edible fungi, and the edible fungi are adsorbed on the surface of the suction cup 20. When it moves to the top, it is transferred by the transfer component. The selection method is to first select the edible fungi with smaller volume and mass, and then adsorb the edible fungi with larger volume and mass, thereby achieving the effect of selecting edible fungi of the same specification to enter the same packaging box 4;

[0051] When the suction cup 20 sucks the edible fungi and rotates to the top of the suction roller 7, the metal ball 24 will fall under the action of gravity and be blocked by the blocking rod. The centrifugal force generated by the rotation is not enough to overcome the weight of the metal ball 24. At this time, since the suction force cannot pass through the side tube 23 in large quantities, the edible fungi above can be easily transferred away by the transfer component. As the suction roller 7 continues to rotate, when the metal ball 24 crosses the horizontal line, under the action of inertia and gravity, the metal ball 24 will move to the position of the suction cup 20, allowing the suction force to pass through the side tube 23 and normally adsorb the edible fungi. The metal ball 24 has a large mass and its own gravity is enough to get rid of the suction force.

[0052] The driving motor 16 drives the active disk 17 to rotate, thereby driving the adsorption roller 7 to rotate, so that the adsorption roller 7 continuously adsorbs the edible fungi, and at the same time, the two active disks 17 do not contact the suction cup 20;

[0053] When the suction cup 20 absorbs the edible fungi and transfers them upward to the top, the suction force is greatly reduced. As the adsorption roller 7 continues to rotate counterclockwise, the edible fungi will be moved to the surface of the belt 13. The belt 13 also rotates counterclockwise under the drive of the second driving motor. With the friction of the belt 13, the edible fungi can be transferred to the top of the belt 13. Since the positions of the transmission rod 12 and the support column 11 are always fixed, the edible fungi transported backward will eventually be transported to the top of the positioned packaging box 4 and fall into it. Through this arrangement, the edible fungi of the same specifications are screened and sent to the packaging box 4 one by one. After the predetermined time of transportation, another batch of packaging boxes 4 is replaced. If more accurate filling of edible fungi is required, optical equipment can be added to one side of the conveyor belt 3 for real-time observation.

[0054] The guide plate 15 is provided to ensure that the belt 13 can maintain a relatively stable shape when the adsorption roller 7 rotates to adjust the angle, and will not affect the work of other parts. The structural setting of the belt 13 can well protect the edible fungi from falling to both sides, and the protrusions on the surface can increase the friction, so that the edible fungi can be normally transported in the direction of the conveyor belt 3;

[0055] When the edible fungi are put into the packaging box 4, the height of the belt 13 is substantially level with the packaging box 4, and no large kinetic energy is generated. At the same time, the edible fungi bouncing into the packaging box 4 will be blocked by the pressure strip 21 to prevent the edible fungi from popping out of the packaging box 4.

[0056] The upper crotch guard 9 is set to reduce the problem that the edible fungi are not completely adsorbed and are thrown out of the selection plate 6 by inertia during the rotation of the adsorption roller 7. The series table 10 allows the four selection plates 6 to move at the same time to reduce the control difficulty;

[0057] During the adsorption process of the adsorption roller 7, the four selection plates 6 are controlled to swing slightly horizontally through the screw nut mechanism 1, so that the sliding ball 25 is constantly shaking inside, thereby hitting the swinging of the undulating pad 26, and the edible fungi at the bottom can be rolled upward, so that the edible fungi inside can be more evenly selected by the suction force. After each selection period, new edible fungi are put into the selection plate 6 through two sets of feeding buckets 2.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
