Description

Technical Field

[0001] The present application belongs to the field of melon and vegetable transportation, and specifically relates to a convenient melon and vegetable picking and transporting machine. Technical Background

[0002] Since growing crops in greenhouses requires setting up trellises and laying film for insulation, the cost of growing crops in greenhouses is higher than growing crops in the open air. This makes the land in greenhouses valuable. In order to achieve a higher land utilization rate, crops in greenhouses are planted more densely.

[0003] Furthermore, in the process of picking and transporting crop fruits, it is not convenient for some traditional transportation and harvesting machinery to enter the agricultural greenhouse for operation, so the harvesting of melons and vegetables in the greenhouse is done manually by agricultural workers.

[0004] In addition, in order to achieve a higher land utilization rate and the narrow roads for people to enter and exit the greenhouse, the existing technology generally adopts track-type fruit picking and transportation devices for agricultural greenhouses to transport fruits and vegetables in the greenhouse, transport the vegetables outside the greenhouse and then transport them to the transport vehicles.

[0005] In the prior art, there is an application number CN.201921612888.9, and the patent name is a patent application for a rail transport device for fruit picking vehicles, which can ensure the safe transportation of agricultural fruits. The groove on the top of the base can increase the stability of the transport box on the base, and the coordinated design of the buffer damping mechanism can reduce the vibration of the transport box when it collides with other objects, further protecting the integrity of the fruits inside the transport box, thereby improving the transportation performance of the device, thereby improving the transportation efficiency of the device, and avoiding the labor-consuming and time-consuming process of manual picking and transportation of agricultural fruits.

[0035] See also Figures 1 to 6 ,like Figures 1 to 5 As shown, in a specific embodiment of the present application, there is a portable vegetable picking and transporting machine, comprising:

[0036] A frame 100, the frame 100 comprising a base frame 110 and a vertical support frame 120 disposed at one end of the base frame 110;

[0037] A walking mechanism 200 disposed below the frame 100, the walking mechanism 200 is preferably a bidirectional walking mechanism 200, such as a bidirectional foot pedal, etc., which can move forward and backward in a straight line without turning around;

[0038] A lifting mechanism 300 disposed on the frame 100, the lifting mechanism 300 may be any lifting mechanism 300 such as a telescopic top rod, a scissor-type lifting mechanism 300 or a gear lifting mechanism 300;

[0039] The portable transport mechanism 400 is arranged on the lifting mechanism 300. The portable transport mechanism 400 can be driven up and down by the lifting mechanism 300. The portable transport mechanism 400 includes a transport base plate 410 and an extension slide rail 420. The transport base plate 410 is arranged on the lifting mechanism 300. The extension slide rail 420 is hinged to one end of the transport base plate 410 toward the vertical support frame 120, and the extension slide rail 420 is placed on the vertical support frame 120. The transport base plate 410 is used to transport the melon transport box 500 to the extension slide rail 420. The transport base plate 410 It may be a trapezoidal plate with a top having a certain inclination toward the extension rail 420, the extension rail 420 is arranged on the transfer bottom plate 410 and is hinged to the transfer bottom plate 410, when the extension rail 420 is unfolded, the transfer bottom plate 410 can transfer the melon transport box 500 to the extension rail 420, and the melon transport box 500 transferred to the extension rail 420 can slide along the extension rail 420; and

[0040] The melon transport box 500 can be slidably engaged with the extension rail 420 .

[0041] In a specific implementation process, the transfer bottom plate 410 is a trapezoidal plate with a certain inclination on the top of the extension rail 420 as described above. The convenient vegetable picking conveyor enters the greenhouse from the path in the greenhouse and stops at the harvesting area. At this time, the lifting mechanism 300 does not lift the transfer bottom plate 410, and the extension rail 420 hinged on the transfer bottom plate 410 is not unfolded. The extension rail 420 is placed on the vertical support frame 120. After the staff cuts the vegetables (watermelon, cucumber, wild rice melon, etc.) from the vines in the harvesting area in the greenhouse, the vegetables (watermelon) are , cucumber, wild rice squash, etc.) are collected into the melon transport box 500, and then the filled melon transport box 500 is moved to the transfer bottom plate 410, and the melon transport box 500 is placed on the trapezoidal transfer bottom plate 410 with a certain inclination on the top extending the slide rail 420, and will slide down the extension slide rail 420 under the dual effects of gravity potential energy and the top of the extension slide rail 420 with a certain inclination, but because the extension slide rail 420 is not unfolded, the extension slide rail 420 is placed on the vertical support frame 120, and the unfolded extension slide rail 420 will block the melon transport box 500 on the transfer bottom plate 410. When the loading bottom plate is filled with filled melon boxes 500, the portable vegetable picking conveyor leaves the greenhouse and arrives at the side of the transport vehicle. At this time, the lifting mechanism 300 rises and lifts the transfer bottom plate 410 to a height higher than the height of the transport vehicle compartment. During this process, the extension rail 420 is unfolded around the hinge point and slides on the vertical support frame 120 and is set up on the transport vehicle compartment. At this time, the hinged end of the extension rail 420 is higher than the end set on the compartment. The transfer bottom plate 410 then transfers the melon box 500 to the extension rail 420, or the staff lifts the melon box 500 from the transfer bottom plate 410. Pushed to the extended slide rail 420, the melon transport box 500 slides along the top of the inclined transfer base plate 410 to the extended slide rail 420 under the action of gravitational potential energy. Since one end of the extended slide rail 420 hinged to the transfer base plate 410 is higher than the end placed on the carriage, the melon transport box 500 transferred to the extended slide rail 420 will slide on the extended slide rail 420 into the carriage. After all the melon transport boxes 500 on the portable melon and vegetable picking conveyor are unloaded into the carriage, the lifting mechanism 300 descends, so that the portable melon and vegetable picking conveyor returns to its initial state, and the portable melon and vegetable picking conveyor enters the greenhouse again.

[0042] The beneficial effects of the above implementation process are:

[0043] First, it solves the problem that the existing technology of the fruit picking vehicle rail transport device requires laying tracks in each greenhouse, without the need to lay a large number of tracks, thus avoiding the high cost of laying tracks;

[0044] Second, the melon transport box 500 filled with melons and vegetables is directly transferred to the carriage through the extended slide rail 420, which saves time and effort, eliminates the need for workers to transport the melons and vegetables to the transport vehicle, and avoids the safety hazard of melons and vegetables rolling down and injuring workers during transportation.

[0045] As described above, when the transfer base plate 410 transfers the melon transport box 500 to the extension slide rail 420, the melon transport box 500 may shift during the transfer process, causing the melon transport box 500 to deviate from the extension slide rail 420 when transferred to the extension slide rail 420, thereby falling or getting stuck between the transfer base plate 410 and the extension slide rail 420. In a possible embodiment, the portable transfer mechanism 400 also includes a fixed slide rail 430, which is arranged on the transfer base plate 410, and the fixed slide rail 430 is arranged in connection with the extension slide rail 420, the melon transport box 500 can be stuck on the fixed slide rail 430, the extension slide rail 420 is hinged to the transfer base plate 410, and the extension slide rail 420 is connected to the fixed slide rail 430 end to end. In a specific implementation process, when the shipping base plate is filled with melon transport boxes 500 filled with vegetables, and the melon transport boxes 500 are stuck in the fixed slide rail 430, the convenient vegetable picking conveyor drives out of the greenhouse and arrives at the side of the transport vehicle. At this time, the lifting mechanism 300 rises, and lifts the transfer base plate 410 to a height higher than the height of the transport vehicle compartment, and then the extension rail 420 is unfolded around the hinge point and set up on the transport vehicle compartment. At this time, the hinged end of the extension rail 420 is higher than the end set on the compartment, and the transfer base plate 410 then transfers the melon transport box 500 to the extension rail 420. During the transportation process, the melon transport box 500 is stuck on the fixed slide rail 430, so it will accurately move along the The fixed slide rail 430 moves without causing deviation problems. Under the action of gravitational potential energy, the melon transport box 500 slides along the top of the inclined transfer base plate 410 to the extension slide rail 420. At this time, the melon transport box 500 is again clamped on the extension slide rail 420. Since the end of the extension slide rail 420 hinged to the transfer base plate 410 is higher than the end placed on the carriage, the melon transport box 500 transferred to the extension slide rail 420 will slide on the extension slide rail 420 into the carriage. After all the melon transport boxes 500 on the portable melon and vegetable picking conveyor are unloaded into the carriage, the lifting mechanism 300 descends, so that the portable melon and vegetable picking conveyor returns to its initial state, and the portable melon and vegetable picking conveyor enters the greenhouse again. The beneficial effects of the above implementation process are: ensuring that the melon transport box 500 does not deviate from the extended slide rail 420 during transportation, enabling the melon transport box 500 to be accurately inserted into the extended slide rail 420, and ensuring that the melon transport box 500 does not tip over due to deviation from the extended slide rail 420 during transportation.

[0046] As described above, after the melon transport box 500 has been used for many times, the clamping structure used to clamp on the extension rail 420 may be damaged, which may cause the melon transport box 500 to easily tip over when sliding on the extension rail 420. In a possible embodiment, the number of the extension rails 420 is multiple, and the multiple extension rails 420 are arranged parallel to each other, the number of the extension rails 420 is ≥, and two adjacent extension rails 420 are arranged parallel to each other.

[0047] The beneficial effect of the above embodiment is that the multiple extension rails 420 can ensure that even if a certain clamping structure used to clamp on the extension rail 420 is damaged, there is still an intact clamping structure that can clamp the melon transport box 500 on the remaining extension rails 420, so that the melon transport box 500 can slide along the extension rails 420 to the transportation equipment.

[0048] In another implementation process, there are more than two extension rails 420 and only one fixed rail 430, so that the melon transport box 500 can slide along one fixed rail 430 to the extension rail 420, and the melon transport box 500 can be accurately connected to the extension rail 420.

[0049] Furthermore, there are multiple fixed rails 430, and the multiple fixed rails 430 are arranged in parallel with each other, and the multiple fixed rails 430 correspond one-to-one with the multiple extension rails 420. Although there is only one fixed rail 430, the melon transport box 500 can be slid along one fixed rail 430 to the extension rail 420, so that the melon transport box 500 is accurately snapped onto the extension rail 420. However, the one-to-one correspondence between the multiple fixed rails 430 and the multiple extension rails 420 can ensure that each snap-on structure of the melon transport box 500 can be accurately aligned from the fixed rail 430 to the extension rail 420, and transferred to the extension rail 420.

[0050] The beneficial effect is that the one-to-one correspondence between the multiple fixed slide rails 430 and the multiple extension slide rails 420 can ensure that each clamping structure of the melon transport box 500 can be accurately aligned from the fixed slide rail 430 to the extension slide rail 420.

[0051] As described above, the inclined transfer bottom plate 410 only relies on the downward force generated by the inclined plane to make the melon transport box 500 slide toward the extension slide rail 420. Although such a technical solution can achieve the technical effect of transferring the melon transport box 500, it is unreliable in some cases. For example, due to factors such as climate or environment, the friction coefficient between the melon transport box 500 and the transfer bottom plate 410 increases, so that the melon transport box 500 is fixed on the transfer bottom plate 410 under the action of a large friction force, resulting in the melon transport box 500 cannot be successfully transferred to the extension slide rail 420. In a possible embodiment The transfer bottom plate 410 includes a bottom plate body 411, a transfer wheel set 412 and a first driving member 413. The bottom plate body 411 is arranged on the lifting mechanism 300. The transfer wheel set 412 can be rotatably arranged on the bottom plate body 411, and the rotation direction of the transfer wheel set 412 is the same as the length direction of the extension slide rail 420. The transfer wheel set 412 is in contact with the melon transport box 500. Because the transfer bottom plate 410 is inclined, the melon transport box 500 generates an oblique downward component force, and the oblique downward component force is connected to the melon transport box 500 through the transfer wheel set 412. The first driving member 413 is arranged on the back side of the bottom plate body 411 and is connected to the transfer wheel group 412 by transmission. The first driving member 413 is arranged on the bottom plate body 411 and is used to drive the transfer wheel group 412. The first driving member 413 drives the transfer wheel group 412 to roll in the direction of the extension rail 420. Since the transfer wheel group 412 is in contact with the melon transport box 500, the first driving member 413 causes the transfer wheel group 412 to roll. The driving force of the rolling of the group 412 will generate friction force on the melon transport box 500 (the friction force is in the direction of the extension rail 420). The greater the friction force (for example, due to the increase in the friction coefficient between the melon transport box 500 and the transfer bottom plate 410 due to factors such as climate or environment as mentioned above), the better the transfer effect of the rolling of the transfer wheel group 412 on the melon transport box 500, that is, the closer the distance that the melon transport box 500 moves toward the extension rail 420 after the transfer wheel group 412 rolls one circle (that is, the linear displacement of the surface of the transfer wheel group 412 is the circumference of the transfer wheel group 412). The beneficial effect is: the problem of poor reliability of the melon transport box 500 sliding to the extension rail 420 due to the inclined transfer bottom plate 410 is solved, and the melon transport box 500 is actively transferred by rolling the transfer wheel group 412, so as to achieve the beneficial effect of enhancing the reliability of the transfer process.

[0052] As described above, the snap-fit ​​structure provided below the melon transport box 500 can be a through slot or snap-fit ​​ring that fits the fixed slide rail 430 and the extended slide rail 420, or can be other snap-fit ​​structures. Considering that the cost of the material required for the through slot is too high, and the complex structure of the snap-fit ​​ring is easily damaged, in a possible embodiment, the melon transport box 500 includes a box body 510 and a sliding slot plate 520. The box body 510 is used to store melons and vegetables. The sliding slot plate 520 is provided below the box body 510. The sliding slot plate 520 is provided with a slide slot 521, and the slide slot 521 can slide with the extended slide rail 420. The beneficial effect is that the sliding slot plate 520 and the slide slot 521 provided thereon not only achieve the effect of providing a through slot, but also achieve the beneficial effect of saving materials and low cost.

[0053] As mentioned above, there are two situations. On the one hand, if an inclined transfer base plate 410 is used to make the melon transport box 500 slide toward the extension slide rail 420, the friction coefficient of the contact surface between the melon transport box 500 and the transfer base plate 410 needs to be small (at this time, the friction force on the melon transport box 500 is the resistance that hinders the melon transport box 500 from sliding toward the extension slide rail 420), so that the resistance that hinders the melon transport box 500 from sliding toward the extension slide rail 420 becomes smaller. On the other hand, if a transfer base plate 410 with a transfer wheel group 412 is used, the friction force generated by the rotation of the transfer wheel group 412 is used to move the melon transport box 500 toward the extension slide rail 420, the melon transport box 500 needs to be small. The friction coefficient of the contact surface between 500 and the transfer bottom plate 410 is relatively large (at this time, the friction force on the melon transport box 500 is the force that helps the melon transport box 500 to roll on the transfer wheel set 412 to be transported to the extension slide rail 420), which increases the force that helps the melon transport box 500 to be transported to the extension slide rail 420. In a possible embodiment, the melon transport box 500 also includes a strip friction member 530, which is arranged below the box body 510, and the length direction of the strip friction member 530 is parallel to the length direction of the extension slide rail 420, and the strip friction member 530 is in contact with the transfer wheel set 412. The melon transport box 500 also includes a strip friction member 530, which is arranged below the box body 510 and between the sliding slot plates 520, corresponding to the position of the transfer wheel group 412. The strip friction member 530 can be a flat plate, the upper end of which is fixed to the melon transport box 500, and the lower end is a plane that contacts the inclined transfer bottom plate 410 or the transfer wheel group 412. As mentioned above, when the inclined transfer bottom plate 410 is used to slide the melon transport box 500 through the gravity potential energy to achieve the transfer effect, the friction coefficient of the lower end plane of the strip friction member 530 is reduced, and the transfer effect is reduced. The relatively smooth surface of the strip friction member 530 makes the melon transport box 500 suffer less friction (the friction force on the melon transport box 500 at this time is the resistance that prevents the melon transport box 500 from sliding toward the extension slide rail 420). As mentioned above, when the transfer wheel set 412 is used to achieve the transfer effect, the friction coefficient of the lower end plane of the strip friction member 530 is increased, and the relatively rough surface of the strip friction member 530 is used to make the melon transport box 500 suffer greater friction (the friction force on the melon transport box 500 at this time is the force that helps the melon transport box 500 roll on the transfer wheel set 412 to be transported toward the extension slide rail 420). The beneficial effect is: no matter which of the above transfer methods is adopted to transfer the melon transport box 500 to the extension slide rail 420, the friction coefficient of the strip friction member 530 can be adjusted to achieve a better transfer effect.

[0054] Furthermore, the number of the sliding slot plates 520 is multiple, and the multiple sliding slot plates 520 are sequentially arranged in the length direction of the extension rail 420, and reinforcing ribs 540 are connected between the sliding slot plates 520. The beneficial effect is: reinforcing the thin sliding slot plate 520 structure and increasing the service life of the sliding slot plate 520.

[0055] As described above, when the extension rail 420 is unfolded, due to the different heights of the transport vehicles, the other end of the unfolded extension rail 420 may not be able to be accurately mounted on the carriage of the transport vehicle, and the extension rail 420 only relies on the forces at both ends to support the melon transport box 500, which can easily lead to bending of the extension rail 420 and a short service life. In a possible embodiment, the portable melon and vegetable picking and transporting machine also includes a support assembly 600, and the vertical support frame 120 is provided with an adjustment groove 121 and a plurality of first locking holes 122 vertically arrayed along the adjustment groove 121, and the support assembly 600 includes a connected support sliding member 610 and a locking assembly 620, the support sliding member 610 is slidably matched with the adjustment groove 121, the locking assembly 620 can be locked with the first locking hole 122, and a support groove 611 is provided at the upper end of the support sliding member 610. The extension slide rail 420 is movably matched with the support groove 611. The movably matched means that when the hinged end of the extension slide rail 420 rises with the transfer base plate 410, the extension slide rail 420 slides in the support groove 611. Since the hinged end rises with the transfer base plate 410, and the height of the support groove 611 remains unchanged, the extension slide rail 420 will rotate around the contact point in the support groove 611 at a certain angle while sliding. The beneficial effects are as follows: the support groove 611 is arranged corresponding to the extension slide rail 420, and the extension slide rail 420 is stuck in the support groove 611 before and after being unfolded. When the extension slide rail 420 is unfolded, the height of the other end of the unfolded extension slide rail 420 is further adjusted by adjusting the support member to slide up and down in the adjustment groove 121 to adjust the height of the support groove 611, so that it can better adapt to different transport vehicles, and the extension slide rail 420 is stuck in the support groove 611 after being unfolded. The support groove 611 provides a third support point for the extension slide rail 420 between the two ends, which can avoid excessive radial force on the extension slide rail 420, avoid bending, and further increase the service life of the extension slide rail 420.

[0056] Furthermore, the locking assembly 620 includes a locking plate 621, a latch pin 622, a spring 623 and an adjusting handle 624. The locking plate 621 is arranged on one side of the supporting sliding member 610. The locking plate 621 is provided with a second locking hole. One end of the spring 623 is fixed to the locking plate 621, and the other end of the spring 623 is fixed to the latch pin 622. The latch pin 622 is movably matched with the second locking hole. The adjusting handle 624 is arranged on the locking plate 621. In a specific embodiment, in the initial state, the latch 622 is pulled toward the first locking hole 122 by the spring 623, and penetrates the first locking hole 122 and the second locking hole at the current position, so that the first locking hole 122 and the second locking hole at the current position are stuck by the latch 622.
