Description

Technical Field

[0001] The invention belongs to the technical field of pineapple picking, and in particular relates to a multifunctional pineapple picking, conveying and post-processing machine and a working method. Background Art

[0002] Pineapples are loved by growers because of their good taste. In terms of agricultural planting, growers usually need to choose suitable varieties and planting locations, adopt appropriate farming and irrigation techniques, and effective pest and disease control measures to ensure the growth and maturity of pineapples; before picking, growers need to carefully inspect the pineapple fields to determine which pineapples have reached the maturity standard; this usually requires judgment based on the color, weight and aroma of the pineapples; at the same time, growers also need to prepare picking tools, such as scissors or pickers, and necessary protective equipment, such as gloves and hats; when picking, workers usually line up in a row and pick by hand along the pineapple field; they use scissors or pickers to cut from the roots of the pineapple to ensure that the fruit can be picked intact from the plant; during the picking process, care must be taken not to damage the fruit to prevent affecting its quality; the picked pineapples will be immediately subjected to preliminary processing, such as removing the top leaves to expose the top of the fruit for easy transportation and further processing.

[0003] In the prior art, pineapples are usually picked manually, and the skin and core of the picked pineapples need to be removed. Picking, peeling and core removal are divided into three steps, and picking, peeling and core removal cannot be integrated.

[0004] For example, the Chinese patent application number is 202410116109.5, and the publication date is 2024.03.29, which discloses a glass combined harvester with a directional flexible fruit puller and a vibrating conveying mechanism, including a vehicle body, a picking device and a conveying device; the picking device includes a frame and a picking mechanism; the picking mechanism includes a fruit receiving plate arranged on the frame and a directional flexible fruit puller, the directional flexible fruit puller includes a plurality of groups of flexible fruit holding rod groups and a fruit pulling driving mechanism for driving the flexible fruit holding rod groups to maintain a vertical posture to perform fruit pulling movement; the conveying device includes a conveyor belt and a vibrating conveying mechanism; the vibrating conveying mechanism includes two rows of toothed screen groups arranged alternately and a vibrating conveying driving mechanism for driving the two rows of toothed screen groups to perform alternating reciprocating motions. The pineapple combined harvester can push the pineapple fruit backwards to pick the fruit, adapt to the harvesting of pineapple fruits in various postures, and realize the low-loss transportation of pineapple fruits, and the transportation process will not be blocked, thereby increasing the efficiency of batch harvesting of fruits.

[0005] However, the document only collects the fruits after picking by cutting, but cannot perform the operations of picking, peeling and coring at one time, which makes the whole picking process inefficient. Summary of the invention

The second conveying assembly includes more than two partitions, and a pineapple conveying space is formed between adjacent partitions. The lower end of the second conveying assembly is located at the output end of the first conveying assembly; The peeling and core removing mechanism is arranged at the rear end of the picking machine body and at the output end of the second conveying assembly, and is used for peeling and core removing the pineapple.

[0008] The working method of the above-mentioned multifunctional pineapple picking, conveying and post-processing machine comprises the following steps: S1, picking: controlling the operation of the lifting and adjusting component, which drives the picking plate to move up and down through a rotation drive, so that the blade of the L-shaped cutting plate is located at the root of the pineapple; S2, picking drive operation, the picking drive drives the two L-shaped cutting plates to move towards each other, the two L-shaped cutting plates cut off the pineapple roots, and the cut pineapples are located on the surfaces of the two L-shaped cutting plates; S3, the rotary drive is started, and the first drive is started at the same time. The rotary drive drives the picking plate to rotate through its output end, and the end of the picking plate away from the picking machine body tilts upward.

Restart the second conveying assembly to convey the peeled and cored pineapples out.

[0009] The multifunctional pineapple picking, conveying and post-processing machine and working method firstly acts on the root of the pineapple through the blades of two relatively parallel L-shaped cutting plates, thereby giving two parallel shearing forces to the root of the pineapple, and a picking drive is arranged on the outer side of the L-shaped cutting plate, and the output end of the picking drive is connected to the outer side of the L-shaped cutting plate, so that the picking drive exerts a uniform force on the L-shaped cutting plate, and thus the picking effect is good. When the pineapple is picked, a bearing surface is formed on the upper surface of the blade of the L-shaped cutting plate due to the setting of the L-shaped cutting plate, and since the diameter of the root of the pineapple is smaller than the diameter of the pineapple itself, when the pineapple is picked by the L-shaped cutting plate and the L-shaped cutting plate does not move outward, the upper surface of the blade of the L-shaped cutting plate carries the picked pineapple, which is convenient for the subsequent transportation of the picked pineapple. Then, the picking plate is driven to rotate by a rotary drive, and the picked pineapples fall from the feed port into the hopper along the L-shaped cutting plate under the action of their own gravity. Under the action of the vibration motor, the pineapples move toward the discharge port. Since the cross-section of the discharge port is rectangular, and the shape of the pineapple is usually longer in the length direction than in the width direction, the pineapple can be oriented by the discharge port, so that the pineapple can fall reliably into the pineapple receiving groove, which is convenient for the position correspondence with the peeling and core removal mechanism when the pineapple is peeled and cored. Then, the pineapple is transported to the pineapple conveying space of the second conveying component by the first conveying component, and the pineapple is lifted to the peeling and core removal mechanism by the second conveying component. At this time, the second conveying component is paused for a time h, and the pineapple is peeled and cored by the peeling and core removal mechanism, and then the peeled and cored pineapple is transported out by the second conveying component. Therefore, picking, peeling and core removal are integrated, the picking efficiency is high, and the reliability of transportation is good.

[0010] Furthermore, the lifting and adjusting assembly includes a track rod, a first hydraulic cylinder and a track slider. The track rod is fixed to one side of the front end of the picking machine body. The track slider is slidably connected to the track rod. The first hydraulic cylinder is fixedly connected to the upper end of the track rod. The piston rod of the first hydraulic cylinder moves through the track rod and is fixed to the track slider. The rotation drive is installed on the track slider. In this structure, when the first hydraulic cylinder is working, the piston rod of the first hydraulic cylinder drives the track slider to slide in the track rod, and the track slider drives the picking assembly to move up and down, thereby achieving the function of adjusting the height of the L-shaped cutting board in the picking assembly. The track slider is guided by the track rod, and the movement reliability of the track slider is better.

[0011] Further, the second conveying assembly includes a first fixed plate, a second fixed plate, a second rotating roller, a second motor and a second conveyor belt, the first fixed plate, the second fixed plate and the second rotating roller are each provided with two, the two first fixed plates are respectively fixedly connected to the lower end of the picking machine body, the two second fixed plates are respectively fixedly connected to the upper end of the picking machine body, one of the second rotating rollers is rotatably connected between the two first fixed plates through a second rotating shaft, the other second rotating roller is rotatably connected between the two second fixed plates through a second rotating shaft, the second conveyor belt transmission sleeve is arranged between the two second rotating rollers, a plurality of the partitions are all fixedly connected to the surface of the second conveyor belt, the second motor is fixedly connected to one of the second fixed plates, and the output end of the second motor is fixed to one end of one of the second rotating shafts. In this structure, when the second motor is working, the output end of the second motor drives one of the second rotating shafts to rotate, the second rotating shaft drives the second rotating roller connected thereto to rotate, the second rotating roller drives the second conveyor belt to move, thereby driving the partition to move, and the pineapples falling into the pineapple conveying space are lifted through the partition, so that the reliability of pineapple conveying is better.

[0012] Furthermore, the peeling and core removing mechanism includes a third fixed plate, a first electric push rod, a peeling motor, a first hollow support rod, a fourth fixed plate, a second electric push rod, a mounting seat, a second hollow support rod, a third electric push rod, a core removing rod, a knife seat and a peeling knife; the third fixed plate is fixedly connected to one side of the rear end of the picking machine body, the first electric push rod is fixedly connected to the third fixed plate, the peeling motor is installed at the output end of the first electric push rod, and one end of the first hollow support rod is connected to the output end of the peeling motor; the fourth fixed plate is fixedly connected to the other side of the rear end of the picking machine body, the second electric push rod is fixedly connected to the fourth fixed plate, the mounting seat is installed at the output end of the second electric push rod, the second hollow support rod is rotatably installed on the mounting seat, the second hollow support rod is coaxial with the first hollow support rod, the third electric push rod is installed in the second hollow support rod, one end of the core removing rod is connected to the output end of the third electric push rod, and the core removing rod is slidably arranged in the second hollow support rod; the knife seat is installed at the rear end of the picking machine body, and the peeling knife is installed on the knife seat and is located on one side of the second conveying assembly. According to the structure, when the pineapple is conveyed to the position of the peeling and core removing mechanism by the second conveying assembly, the first electric push rod and the second electric push rod work simultaneously, and the first electric push rod drives the peeling motor to move, and under the action of the first electric push rod, the peeling motor drives the first hollow support rod to move axially toward one end of the pineapple, and at the same time, the second electric push rod drives the mounting seat to move, and the mounting seat drives the second hollow support rod to move axially toward the other end of the pineapple under the action of the second electric push rod, and the pineapple is supported by the first hollow support rod and the second hollow support rod; then, the first electric push rod moves in the opposite direction, and at the same time, the second electric push rod continues to move in the direction of the first electric push rod, and the pineapple is supported by the first hollow support rod and the second hollow support rod. The second hollow support rod brings the pineapple away from the pineapple conveying space of the second conveying assembly. When one end of the pineapple moves to the position of the peeling knife, the peeling motor is started, and the driving motor drives the first hollow support rod, the pineapple, and the second hollow support rod to rotate. When the pineapple continues to move in the direction of the first electric push rod, during the axial movement and rotational movement of the pineapple, the peeling knife cuts off the skin of the pineapple to achieve the purpose of peeling the pineapple. During the peeling process, the third electric push rod drives the core removing rod to move axially and penetrate into the pineapple, thereby removing the pineapple core. The removed pineapple core enters the first hollow support rod. Therefore, peeling and core removing can be carried out at the same time, thereby improving the efficiency of peeling and core removing.When the peeling and core removal work is completed, the peeling motor stops working, and the first electric push rod drives the peeling motor and the first hollow support rod to move in the direction of the second electric push rod, and the second electric push rod drives the mounting seat and the second hollow support rod to move in the direction of the second electric push rod. In this process, the movement speed of the first hollow support rod and the second hollow support rod is the same, and the pineapple is sent back to the pineapple conveying space, and then the second conveying assembly is restarted, and the peeled and cored pineapple is driven to move to the output end of the second conveying assembly through the partition.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, the multifunctional pineapple picking, conveying and post-processing machine includes a picking machine body 1, a lifting and adjusting component, a picking component, a conveying mechanism and a peeling and core removing mechanism.

[0033] See also Figure 1-Figure 5 A multifunctional pineapple picking, conveying and post-processing machine comprises: a picking machine body 1, a lifting and adjusting component, a picking component, a conveying mechanism and a peeling and core removing mechanism.

[0034] The harvesting machine body 1 includes a side support block 101 and a support plate 102. The side support blocks 101 are connected to both sides of the support plate 102, and a space 103 is formed between the support blocks 101 and the support plates 102 on both sides. A through groove 104 for the second conveying assembly to pass through is provided in the middle of the support plate 102 near the rear end. An avoidance groove 1021 that passes through from top to bottom is provided in the middle of the front end of the support plate 102. A wheel frame 201 is installed at the bottom of the side support block 101. The wheel frame 201 is installed at the bottom of the side support block 101. A driving wheel 2 is installed on the wheel frame 201 through an axis and a bearing. In this embodiment, wheel frames 201 are installed at the front and rear ends of the side support block 101, respectively. A driver such as a motor, a hydraulic motor, etc. (not shown in the figure) is installed on the wheel frame 201. The output shaft of the driver is connected to the shaft on the driving wheel 2. When the driver is working, the driver drives the driving wheel 2 to rotate, thereby driving the multifunctional pineapple picking, conveying and post-processing machine to move. As a further improvement of the above technical solution, if Figure 6 As shown, a mounting hole 105 can be provided at the bottom of the side support block 101. The cross section of the mounting hole 105 is a square or other special shape that prevents the wheel frame 201 from rotating in the mounting hole 105.

A spring 204 sleeved on the lifting adjustment bolt 202 is provided between the top surface of the mounting hole 105 and the top surface of the wheel frame 201. When the lifting adjustment bolt 202 is rotated, the wheel frame 201 can be driven to move up and down, thereby adjusting the up and down height of the driving wheel 2, thereby increasing the applicable range of the multifunctional pineapple picking, conveying and post-processing machine. On the one hand, the spring 204 can play a shock-absorbing role. On the other hand, when the spring 204 is compressed, if the wheel frame 201 is adjusted to move downward, the spring 204 can give a rebound force. In this way, the force applied to the lifting adjustment bolt 202 will be reduced, which can save effort.

[0037] There are two groups of picking components, and the two groups of picking components are symmetrically arranged relative to the center line extending forward and backward of the picking machine body. The two groups of picking components are respectively connected to the two groups of lifting and adjusting components, and the two groups of picking components cooperate to realize pineapple picking. The picking components include a rotary drive, a picking plate 303, a picking drive 304 and an L-shaped cutting plate 305. The rotary drive is a motor, the rotary drive is fixedly connected to the guide rail slider 302, the rotary drive has an output end 307, and the rear end of the picking plate 303 is fixed to the output end 307 of the rotary drive; the picking drive 304 is a hydraulic cylinder, the picking drive 304 is fixed to the outside of the picking plate 303, the output end of the picking drive 304 movably penetrates the picking plate 303 and extends to the inner side of the picking plate 303 to form an extension end, the L-shaped cutting plate 305 is fixedly connected to the extension end of the picking drive 304, the L-shaped cutting plate 305 is located on the inner side of the picking plate 303, and a blade 3051 is provided on the inner side of the L-shaped cutting plate 305. A baffle 306 is fixedly connected to the inner side of the two picking plates 303 and at the rear end of the picking plates 303 to prevent the pineapples from falling. The L-shaped cutting plate 305 is located in front of the baffle 306 to avoid interference between the L-shaped cutting plate 305 and the baffle 306.

[0038] In this embodiment, the first hydraulic cylinder 301 in the lifting and adjusting assembly is in operation, and the extension end 3011 of the first hydraulic cylinder 301 drives the track slider 302 to slide in the guide groove 30. The track slider 302 drives the picking assembly to move up and down through rotation, so that the picking assembly is adjusted to a height suitable for picking pineapples. When the picking drive 304 is working, the picking drive 304 can drive the L-shaped cutting plate 305 to move horizontally.

[0039] In this embodiment, the extended end of the picking drive 304 is consistent with the front-to-back length of the L-shaped cutting plate 305, so that the force acting on the L-shaped cutting plate 305 is uniform.

[0040] The conveying mechanism comprises a first conveying assembly and a second conveying assembly, and the first conveying assembly and the second conveying assembly cooperate to realize the conveying of pineapples.

[0041] The first conveying assembly includes a hopper 100 , a fixed plate 5 , a first conveying belt 501 , a first drive 502 , a first rotating roller 503 and a driving plate 504 .

[0042] like Figures 7 to 9 As shown, the hopper 100 includes an upper portion 71, a lower portion 72, a supporting edge 73 and a fixing plate 74. The upper portion 71 is connected to the upper end of the lower portion 72, and the upper portion 71 gradually approaches from top to bottom to form an inclined surface. Specifically, the upper portion 71 is composed of a front side plate, a rear side plate, a left side plate and a rear side plate. The front side plate and the rear side plate gradually approach each other from top to bottom, and the left side plate and the right side plate gradually approach each other from top to bottom. Support edges 73 extend outward from the upper ends of the left plate and the right side plate, respectively, and a fixing plate 74 extending upward is provided at the outer end of the supporting edge 73, so that the fixing plate 74 can be fixed to the picking machine body 1 by bolts. The upper end of the upper part 71 is provided with an inlet 1001, and the lower end of the lower part 72 is provided with an outlet 1002. The inlet 1001 of the hopper 100 is larger than the outlet 1002. The cross section of the outlet 1002 is rectangular. The outlet 1002 faces the first conveyor belt 501. A vibration motor is installed on the hopper 100. The hopper 100 is located in the avoidance groove 1021. When the pineapple enters the hopper 100 from the inlet 1001, the pineapple falls into the outlet 1002 under the action of the vibration motor. Since the cross section of the outlet is rectangular, and the height of a general pineapple is greater than its diameter, the pineapple can fall into the first conveyor belt 501 in a horizontal direction under the action of the vibration motor.

[0043] like Figures 1 to 5As shown, the fixed plate 5 and the first rotating roller 503 are each provided with two, and the two fixed plates 5 are respectively fixedly connected to the two sides of the lower surface of the picking machine body 1. In this example, the fixed plate 5 is fixed to the inner side of the lower end of the side support block 101, and the first rotating roller 503 is rotatably connected at both ends between the two fixed plates 5 through the first rotating shaft. The first conveyor belt 501 is sleeved between the two first rotating rollers 503, and the first drive 502 is fixedly connected to one of the fixed plates 5. The output end of the first drive 502 is fixed to one end of one of the first rotating shafts. More than two drive plates 504 are arranged on the outer surface of the first conveyor belt 501, and pineapple receiving grooves 5041 are formed between adjacent drive plates 504. In this embodiment, the distances between adjacent drive plates 504 are equal; the first drive 502 is a first motor. In this embodiment, the distance L between the upper end surface of the upper end drive plate 504 and the lower end surface of the hopper 100 is greater than the diameter of the pineapple and less than the height of the pineapple. In this structure, when the first drive 502 is working, the first drive 502 drives the first rotating roller 503 connected thereto to rotate through the first rotating shaft, the first rotating roller 503 drives the first conveyor belt 501 to move, and the first conveyor belt 501 drives the driving plate 504 to move. When the pineapple falls into one of the pineapple receiving grooves 504, the moving driving plate 504 drives the pineapple to move to the rear end and enter the second conveying assembly.

[0044] like Figures 1 to 5As shown, the second conveying assembly is arranged at the rear end of the picking machine body 1, and the second conveying assembly is inclined from bottom to top toward the rear end of the picking machine body 1. The second conveying assembly includes a first fixed plate 6, a second fixed plate 601, a second rotating roller 604, a second motor 605, a second conveyor belt 602 and more than two partitions 603, the first fixed plate 6, the second fixed plate 601 and the second rotating roller 604 are each provided with two, the two first fixed plates 6 are respectively fixedly connected to the two sides of the lower end of the picking machine body 1, the first fixed plate 6 is an L-shaped plate, the two second fixed plates 601 are respectively fixedly connected to the two sides of the upper end of the picking machine body 1, the second fixed plate 601 is L-shaped, and one of the second rotating rollers 60 4 is rotatably connected between the two first fixed plates 6 through the second rotating shaft, another second rotating roller 604 is rotatably connected between the two second fixed plates 601 through the second rotating shaft, the second conveyor belt 602 is sleeved between the two second rotating rollers 604, the partitions 603 are all fixedly connected to the surface of the second conveyor belt 602, and a pineapple conveying space 6031 is formed between adjacent partitions 603, the second motor 605 is fixedly connected to one of the second fixed plates 601, and the output end of the second motor 605 is fixed to one end of one of the second rotating shafts. In this structure, when the second motor 605 is working, the second motor 605 drives the second rotating roller 604 to rotate through the second rotating shaft connected thereto, the second rotating roller 604 drives the second conveyor belt 602 to move, and the second conveyor belt 602 drives the partition 603 to move. When the pineapple enters the pineapple conveying space 6031, the pineapple is lifted to the position of the peeling and core removal mechanism under the action of the moving partition 603.

[0045] like Figures 1 to 5 As shown, the peeling and core removing mechanism is arranged at the rear end of the picking machine body 1 and at the output end of the second conveying assembly, and is used for peeling and core removing the pineapple.

[0046] The peeling and core removing mechanism includes a third fixed plate 801, a first electric push rod 802, a peeling motor 803, a first hollow support rod 804, a fourth fixed plate 805, a second electric push rod 806, a mounting seat 807, a second hollow support rod 808, a third electric push rod 809, a core removing rod 8010, a knife seat 91 and a peeling knife 92.

[0047] like Figures 1 to 5 , Fig.10 and Fig.11As shown, the third fixing plate 801 is L-shaped, and the third fixing plate 801 is fixedly connected to one side of the rear end of the picking machine body 1, the first electric push rod 802 is fixedly connected to the third fixing plate 801, and the peeling motor 803 is installed at the output end of the first electric push rod 802, and one end of the first hollow support rod 804 is connected to the output end of the peeling motor 803, and the first hollow support rod 804 has a first hollow cavity 8042, and the first hollow cavity 8042 extends axially, and the first hollow cavity 8042 is used to receive pineapple cores, and a drop hole 8041 is provided at one end of the first hollow support rod 804 close to the peeling motor 803. When the pineapple cores entering the first hollow cavity 8042 are full, the pineapple cores near the drop hole 8041 are pushed by the new pineapple cores entering the first hollow cavity 8042. The pineapple core falls from the drop hole 8041, which is convenient for timely discharge of the pineapple core; the fourth fixed plate 805 is fixedly connected to the other side of the rear end of the picking machine body 1, the second electric push rod 806 is fixedly connected to the fourth fixed plate 805, the mounting seat 807 is mounted on the output end of the second electric push rod 806, the second hollow support rod 808 is rotatably mounted on the mounting seat 807, the second hollow support rod 808 is provided with an axially extending second hollow cavity 8081, the second hollow support rod 808 is coaxial with the first hollow support rod 804, the third electric push rod 809 is installed in the second hollow cavity of the second hollow support rod 808, one end of the core rod 8010 is connected to the output end of the third electric push rod 809, and the core rod 8010 is slidably arranged in the second hollow cavity of the second hollow support rod 808. A storage box 11 is provided at the rear end of the picking machine body 1 and at the output end of the second conveying assembly, and the storage box 11 is used to store peeled and cored pineapples. The knife holder 91 is mounted on the storage box 11 , and the peeling knife 92 is mounted on the knife holder 91 and is located at one side of the second conveying assembly.

[0048] In this example, a waist-shaped groove 921 is provided on the peeling knife 92, and a bolt passes through the waist-shaped groove 921 and is connected to the knife holder 91. In this way, the position of the peeling knife 92 is conveniently adjusted to be suitable for peeling pineapples of different sizes.

[0049] In this example, if Fig.12 As shown, guide rods 93 are respectively arranged on both sides of the peeling knife 92 on the storage box 11, and the knife holder 91 is slidably arranged on the guide rods 93. An adjusting bolt 94 is threadedly arranged on the storage box 11, and the adjusting bolt 94 is threadedly connected with the knife holder 91. When the adjusting bolt is rotated, the knife holder can slide on the guide rods, so that the upper and lower positions of the knife holder can be adjusted, thereby achieving the purpose of adjusting the upper and lower positions of the peeling knife.

[0050] The above peeling and core removing mechanism, such as Fig.11As shown, when the pineapple 1000 is conveyed by the partition 603 to between the first hollow support rod 804 and the second hollow support rod 808, the second conveying assembly stops moving. At this time, the first electric push rod and the second electric push rod work simultaneously. The first electric push rod drives the peeling motor to move. Under the action of the first electric push rod, the peeling motor drives the first hollow support rod to move axially toward one end of the pineapple. At the same time, the second electric push rod drives the mounting seat to move. Under the action of the second electric push rod, the mounting seat drives the second hollow support rod to move axially toward the other end of the pineapple. The pineapple is supported by the first hollow support rod and the second hollow support rod; then, the first electric push rod moves in the opposite direction, and the second electric push rod continues to move toward the first electric push rod. The pineapple is moved toward the first electric push rod, and the pineapple is taken away from the pineapple conveying space of the second conveying assembly through the first hollow support rod and the second hollow support rod. When one end of the pineapple moves to the position of the peeling knife, the peeling motor is started, and the driving motor drives the first hollow support rod, the pineapple, and the second hollow support rod to rotate. When the pineapple continues to move toward the first electric push rod, during the axial movement and rotational movement of the pineapple, the peeling knife cuts off the skin of the pineapple to achieve the purpose of peeling the pineapple. During the peeling process, the third electric push rod drives the core removing rod to move axially and penetrate into the pineapple, thereby removing the pineapple core. The removed pineapple core enters the first hollow support rod. Therefore, peeling and core removing can be carried out at the same time, thereby improving the efficiency of peeling and core removing. When the peeling and core removal work is completed, the peeling motor stops working, and the first electric push rod drives the peeling motor and the first hollow support rod to move in the direction of the second electric push rod, and the second electric push rod drives the mounting seat and the second hollow support rod to move in the direction of the second electric push rod. In this process, the movement speed of the first hollow support rod and the second hollow support rod is the same, and the pineapple is sent back to the pineapple conveying space, and then the second conveying assembly is restarted, and the peeled and cored pineapple is driven to move to the output end of the second conveying assembly through the partition. In the process, the first electric push rod and the second electric push rod are reset to allow the first hollow support rod and the second hollow support rod to separate from the peeled and cored pineapple. This structure has high efficiency in peeling and core removal, and is convenient for conveying peeled and cored pineapples.

[0051] A discharge port 10 is provided on the picking machine body at a position corresponding to the peeling knife position, so that the pineapple peel can fall in through the discharge port 10, so as to collect the pineapple peel.

[0052] like Figures 1 to 14 As shown, the working method of the above-mentioned multifunctional pineapple picking, conveying and post-processing machine includes the following steps: S1. Picking: Control the operation of the lifting and adjusting component, which drives the picking plate to move up and down through a rotation drive, so that the blade of the L-shaped cutting plate is located at the root of the pineapple 1000.

[0053] S2, the picking drive is running, and the picking drive drives the two L-shaped cutting plates to move toward each other. The two L-shaped cutting plates cut off 2000 of the pineapple roots, and the cut pineapples are located on the surfaces of the two L-shaped cutting plates.

[0054] S3. According to the position of the L-shaped cutting plate, the position of the L-shaped cutting plate is adjusted by the lifting adjustment assembly, the rotary drive is started, and the first drive is started at the same time. The rotary drive drives the picking plate to rotate through its output end, and the end of the picking plate away from the picking machine body tilts upward. At this time, the picked pineapples roll into the hopper through the baffle plate, and the vibration motor is started at the same time to make the pineapples entering the hopper fall into the pineapple receiving groove from the discharge port.

[0055] S4, the first drive drives one of the first rotating shafts to rotate, the first rotating shaft drives the first rotating roller connected thereto to rotate, the first rotating roller drives the first conveyor belt to move, and the pineapple is conveyed to the output end of the first conveyor assembly through the driving plate installed on the first conveyor belt. When the pineapple reaches the output end of the first conveyor assembly, the pineapple enters the pineapple conveying space and is lifted to the output end position of the second conveyor assembly by the second conveyor assembly, and the second conveyor assembly stops moving at this time.

[0056] S5, starting the peeling and core removing mechanism, and removing the skin and core of the pineapple through the peeling and core removing mechanism.

[0057] S6. Restart the second conveying assembly to convey the peeled and cored pineapples out.

[0058] The multifunctional pineapple picking, conveying and post-processing machine and working method firstly acts on the root of the pineapple through the blades of two relatively parallel L-shaped cutting plates, thereby giving two parallel shearing forces to the root of the pineapple, and a picking drive is arranged on the outer side of the L-shaped cutting plate, and the output end of the picking drive is connected to the outer side of the L-shaped cutting plate, so that the picking drive exerts a uniform force on the L-shaped cutting plate, and thus the picking effect is good. When the pineapple is picked, a bearing surface is formed on the upper surface of the blade of the L-shaped cutting plate due to the setting of the L-shaped cutting plate, and since the diameter of the root of the pineapple is smaller than the diameter of the pineapple itself, when the pineapple is picked by the L-shaped cutting plate and the L-shaped cutting plate does not move outward, the upper surface of the blade of the L-shaped cutting plate carries the picked pineapple, which is convenient for the subsequent transportation of the picked pineapple. Then, the picking plate is driven to rotate by a rotary drive, and the picked pineapples fall from the feed port into the hopper along the L-shaped cutting plate under the action of their own gravity. Under the action of the vibration motor, the pineapples move toward the discharge port. Since the cross-section of the discharge port is rectangular, and the shape of the pineapple is usually longer in the length direction than in the width direction, the pineapple can be oriented by the discharge port, so that the pineapple can fall reliably into the pineapple receiving groove, which is convenient for the position correspondence with the peeling and core removal mechanism when the pineapple is peeled and cored. Then, the pineapple is transported to the pineapple conveying space of the second conveying component by the first conveying component, and the pineapple is lifted to the peeling and core removal mechanism by the second conveying component. At this time, the second conveying component is paused for a time h, and the pineapple is peeled and cored by the peeling and core removal mechanism, and then the peeled and cored pineapple is transported out by the second conveying component. Therefore, picking, peeling and core removal are integrated, the picking efficiency is high, and the reliability of transportation is good.
