[0002] Agricultural products refer to primary products derived from planting, forestry, animal husbandry and fishery, that is, plants, animals, microorganisms and their products obtained in agricultural activities, such as rice, sorghum, peanuts, corn, wheat and local specialties of various regions.

[0003] In the production and processing of agricultural products, they usually need to go through multiple different links. Especially in the field of deep processing of agricultural products, agricultural products need to be frequently transferred. During the transportation process, conveying devices are needed.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown, an automatic conveying device for fragile agricultural products includes a plurality of storage mechanisms 25 for accommodating fragile agricultural products and a driving mechanism 24 for driving all the storage mechanisms 25. The storage mechanisms 25 include a bottom plate 1, a plurality of elastic support rods 2 are vertically fixedly arranged at the edge of the bottom plate 1, the top ends of all the elastic support rods 2 are commonly fixedly connected to a soft receiving plate 4, a base plate 15 is fixedly connected between the middle parts of all the elastic support rods 2, a plurality of lifting components are arranged on the base plate 15 for lifting and lowering, the upper end of the lifting component is fixedly connected to a middle elastic pad 11, and the middle elastic pad 11 is fixedly connected to the soft receiving plate 4, and the lifting component can pull a part of the soft receiving plate 4 up and down during the lifting process, thereby deforming the soft receiving plate 4 to form a plurality of upward-opening receiving spaces 23, and the receiving spaces 23 are used to accommodate fragile agricultural products.

[0033] The present invention is applicable to agricultural products such as eggs and apples that are easily damaged by collisions. In the present invention, such agricultural products are referred to as fragile agricultural products. When using the present invention to transport fragile agricultural products, the storage mechanism 25 is first adjusted according to the average size of the fragile agricultural products. Specifically, by adjusting the height of the lifting assembly, the lifting assembly is used to drive a portion of the soft receiving plate 4 up and down through the middle elastic pad 11. These portions can be referred to as the lifting portion. When the lifting portion is pulled downward by the lifting assembly and moves downward, the soft receiving plate 4 can form a downward depression, and the inner side of the depression forms a storage space 23. When the lifting portion is pushed upward by the lifting assembly and moves upward, the soft receiving plate 4 can form an upward protrusion. Multiple protrusions can enclose the storage space 23. When the storage space 23 can accommodate one fragile agricultural product, the adjustment of the lifting assembly is completed, and the adjustment of the lifting portion is also completed, that is, the adjustment of the soft receiving plate 4 is completed. Afterwards, the drive mechanism 24 drives the storage mechanism 25 to move. During the movement of the storage mechanism 25, the fragile agricultural products are placed into the storage space 23. The cooperation between the drive mechanism 24 and the storage mechanism 25 enables the transportation of the fragile agricultural products. During the placement of the fragile agricultural products into the storage space 23, the fragile agricultural products may fall directly into the storage space 23, that is, directly onto the soft receiving plate 4. Alternatively, the fragile agricultural products may contact the raised portion and then roll into the storage space 23. Alternatively, the fragile agricultural products may first fall between two adjacent storage spaces 23 and then roll into the storage space 23. Regardless of how the fragile agricultural products enter the storage space 23, they will fall onto the soft receiving plate 4. The impact on the soft receiving plate 4 can be absorbed by the soft receiving plate 4 itself, the elastic support rod 2, and the middle elastic pad 11, thereby avoiding rigid collisions and protecting the fragile agricultural products. In addition, each fragile agricultural product can be individually stored in a storage space 23, and they will not contact each other during transportation, thus preventing the fragile agricultural products from colliding with each other and being damaged.

[0034] In the present invention, the soft receiving plate 4 can be made of sponge and can be covered with a plastic film to prevent dust adhering to the fragile agricultural products from transferring into the pores of the soft receiving plate 4 and causing contamination of the soft receiving plate 4, thereby extending the service life of the soft receiving plate 4. The middle elastic pad 11 can also be made of sponge.

[0035] When receiving fragile agricultural products, the storage mechanism 25 of the present invention can avoid rigid collision with the fragile agricultural products, thereby protecting the fragile agricultural products; moreover, the present invention can store the fragile agricultural products in an independent storage space 23, avoiding mutual collision between fragile agricultural products during transportation, thereby further protecting the fragile agricultural products; in addition, the present invention can adjust the volume of the storage space 23 by adjusting the lifting component to ensure that the fragile agricultural products can be smoothly accommodated.

[0036] The elastic support rod 2 is specifically configured as follows: the elastic support rod 2 includes a sleeve 5 vertically fixed to the base plate 1. A telescopic rod 7 is installed in the sleeve 5 for lifting and lowering. A spring 6 is connected between the lower end of the telescopic rod 7 and the base plate 1, and the upper end of the telescopic rod 7 is fixedly connected to the soft receiving plate 4. When fragile agricultural products fall onto the soft receiving plate 4, the soft receiving plate 4 moves downward and presses the telescopic rod 7 downward, pushing the telescopic rod 7 downward synchronously. The telescopic rod 7 then squeezes the spring 6, compressing it. The spring 6 absorbs the impact energy of the fragile agricultural products on the soft receiving plate 4, thus protecting the fragile agricultural products.

[0037] To further prevent damage to delicate produce from the telescopic rod 7, an edge elastic pad 9 is fixedly attached to the upper end of the telescopic rod 7. This pad is also fixedly connected to the soft receiving plate 4. When delicate produce falls directly on the telescopic rod 7, the edge elastic pad 9 absorbs some of the impact energy, preventing damage to the produce from the strained soft receiving plate 4. The edge elastic pad 9 can be made of the same sponge material as the central elastic pad 11.

[0038] Furthermore, the upper end of the telescopic rod 7 is fixedly connected to the edge elastic pad 9 via a first lining plate 8, and the middle elastic pad 11 is fixedly connected to the lifting assembly via a second lining plate 12. By providing the first lining plate 8 and the second lining plate 12, the size of the edge elastic pad 9 and the middle elastic pad 11 can be increased without increasing the overall volume of the elastic support rod 2 and the lifting assembly, thereby better absorbing the impact energy of fragile agricultural products and achieving protection for them.

[0039] The specific structure of the lifting assembly is as follows: the lifting assembly includes a lifting rod 14 that passes through the base plate 15. The upper end of the lifting rod 14 is fixedly connected to the middle elastic pad 11. The lower end of the lifting rod 14 is connected to a pulling unit for pulling the lifting rod 14 downward. The lower portion of the lifting rod 14 is connected to the lower surface of the base plate 15 via a plurality of elastic cords 17. In the initial state, the pulling unit pulls the lifting rod 14 downward a certain distance. During this process, the lifting rod 14 pulls the elastic cords 17, causing the elastic cords 17 to be in an energy-storing and stretched state, and the soft receiving plate 4 is in a straight state. When it is necessary to form a recessed portion on the surface of the soft receiving plate 4, the pulling unit continues to pull the lifting rod 14 downward. The lifting rod 14 drives the lifting portion downward through the second lining plate 12 and the middle elastic pad 11, thereby forming a recessed portion on the soft receiving plate 4. When a ridge is required on the surface of the soft receiving plate 4, the pulling unit is released, and the elastic cord 17 drives the lifting rod 14 upward. The lifting rod 14 then pushes the lifting portion upward through the second lining plate 12 and the middle elastic pad 11, thereby forming a ridge on the soft receiving plate 4. The lifting assembly only needs to operate the pulling unit to control the lifting rod 14 to rise or fall, thereby facilitating adjustment of the accommodation space 23.

[0040] Furthermore, the lifting rod 14 is fixedly connected to the second lining plate 12 through a plurality of elastic connecting rods 13. The elastic connecting rods 13 can be made of metal rods with a smaller diameter, so as to have better deformation performance, thereby being able to absorb the impact energy of the fragile agricultural products and avoid damaging the fragile agricultural products.

[0041] The specific structure of the pulling unit is as follows: the pulling unit includes a support base 21 fixed to the base plate 1, on which an adjustment motor 22 is fixed. The output shaft of the adjustment motor 22 is connected to the lifting rod 14 via a pull rope 18. When the pulling unit is used to pull the lifting rod 14 downward, the adjustment motor 22 is activated and the pull rope 18 is wound around the output shaft. When the pulling unit needs to be released, the adjustment motor 22 is reversed or powered off. This pulling unit only needs to control the adjustment motor 22, making the control process simpler and easier to implement.

[0042] Furthermore, the pulling unit includes two vertical plates 19 fixed perpendicularly to the base plate 1 and parallel to each other. A guide plate 20 is fixedly connected between the two vertical plates 19. The lower surface of the guide plate 20 is configured as an arc, and the pull rope 18 is passed around the arc. By configuring the vertical plates 19 and the guide plate 20, the guide plate 20 can be used to control the direction of the pull rope 18, ensuring that the pull rope 18 can be smoothly wound onto and unwound from the output shaft of the adjustment motor 22. The provision of the arc prevents the pull rope 18 from excessive friction with the edge of the guide plate 20, which could cause damage to the pull rope 18.

[0043] To facilitate securing the elastic cord 17, a connecting plate 16 is fixedly connected to the lower end of the lifting rod 14. The diameter of the connecting plate 16 is larger than that of the lifting rod 14. The elastic cord 17 is fixedly connected to the edge of the connecting plate 16, and the pull cord 18 is fixedly connected to the lower surface of the connecting plate 16. This arrangement ensures that the elastic cord 17 and the pull cord 18 are staggered, thereby fully preventing interference between the elastic cord 17 and the pull cord 18, thereby ensuring smooth operation of the pulling unit.

[0044] To further protect fragile agricultural products, multiple flexible support pads 10 are fixed to the base plate 15 and staggered with the lifting assembly. These pads can be rubber-supported airbags. After impacting the soft receiving plate 4, fragile agricultural products can continue to fall downward and impact the flexible support pads 10, thereby further absorbing the impact energy and protecting the fragile agricultural products.

[0045] In order to protect the various components between the soft receiving plate 4 and the bottom plate 1, a plurality of side baffles 3 are connected between the edge of the soft receiving plate 4 and the edge of the bottom plate 1. The side baffles 3 are used to close the space between the soft receiving plate 4 and the bottom plate 1, and the side baffles 3 are also set to be flexible plates to avoid damage to fragile agricultural products.

[0046] It should also be noted that, in the present invention, the driving mechanism 24 may adopt conventional conveying devices such as a belt conveyor, which will not be described in detail here.

[0047] The present invention further provides a method for automatically conveying fragile agricultural products. Based on the above-mentioned automatic conveying device for fragile agricultural products, the method includes S1 to S4.

[0048] S1. Determine the fragile agricultural products to be transported.

[0049] S2. Adjust the lifting assembly based on the size data of the fragile agricultural products. Use part of the lifting assembly to pull a portion of the soft receiving plate 4 up and down, thereby deforming the soft receiving plate 4 to form multiple upwardly opening receiving spaces 23. It should be noted that the size data refers to the average size of the fragile agricultural products, and the size can be appropriately expanded based on the average size to ensure that the receiving spaces 23 can successfully accommodate the fragile agricultural products.

[0050] S3. When the accommodating space 23 is able to accommodate the fragile agricultural products, the adjustment of the lifting assembly is completed.

[0051] S4. The driving mechanism 24 is used to drive the storage mechanism 25 to move, and the fragile agricultural products are placed into the accommodating space 23 during the movement of the storage mechanism 25.
