Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a transportation device which is convenient for protecting fruits. Background Art

[0002] Fruit refers to juicy, edible plant fruits with a main taste of sweetness and sourness. Fruits are not only rich in vitamins and nutrients, but also can promote digestion. With the development of the times, people's demand for fruits has increased. In order to meet people's needs, fruit vendors transport fruits from their places of production to supermarkets across the country for sale. After being picked, the fruit is still a living individual, so it will continue to "respire" and "evaporate." Chen Ruyin, a researcher at the Food Industry Development Institute of Taiwan, China, said that "respiration" is what fruits need to maintain life. After harvesting, they will continue to decompose and consume their own nutrients to generate energy and maintain vitality. In respiration, one mole of glucose is oxidized and decomposed to release 2780KJ of energy, of which only about 1160KJ is used to produce ATP, and the rest of the energy is lost in the form of heat energy.

[0003] In the prior art, logistics boxes are commonly used equipment for storing and transporting fruits. They have high structural stability and can effectively protect the fruits stored inside. When in use, the picked fruits are placed in multiple logistics boxes. In order to reduce the horizontal space occupied by multiple logistics boxes and facilitate the storage or transportation of fruits, multiple logistics boxes containing fruits are usually stacked in an overlapping manner so that multiple logistics boxes are stacked into a three-dimensional logistics box pile. The heat dissipated by the respiration of the fruits is often taken away by the free-flowing air around the logistics boxes, thereby cooling the environment around the fruits. However, under the blocking effect of the logistics boxes outside the logistics box pile, it is difficult for the air outside the logistics box pile and the air inside the logistics box pile to circulate and exchange heat, causing heat to accumulate in the internal environment of the logistics box pile, and then the fruits stored in the logistics boxes inside the logistics box pile are in a relatively high temperature environment, so that the fruits deteriorate and rot quickly.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0042] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0043] See also Figure 1-10 The utility model provides a technical solution: a transport device for protecting fruits, comprising a logistics box, the logistics box comprising a bottom plate 11, a plurality of side plates 12 vertically and fixedly connected to the bottom plate 11, the outer contour of the bottom plate 11 is framed by splicing the side plates 12 into a closed loop structure, the bottom plate 11 is a hollow structure, and the bottom plate 11 is provided with a plurality of air inlet holes 111 communicating with the inner and outer sides of the bottom plate 11;

[0044] A support column 13 perpendicular to the bottom plate 11 is provided on the side of the bottom plate 11 facing the side plate 12. The support column 13 is a hollow structure with openings at both ends, and one end of the support column 13 is fixedly connected to the bottom plate 11. A first vent hole 131 connected to the inside of the bottom plate 11 is provided on the side wall of the end of the support column 13 facing the bottom plate 11.

[0045] Through holes connecting the inside and outside of the logistics box are provided on the bottom plate 11 and the side plate 12 to facilitate the free flow of air between the inside and outside of the logistics box, increase the air permeability of the logistics box, and allow the moisture and heat generated by the respiration of the fruit in the logistics box to diffuse into the surrounding air in time, reducing the chance of fruit damage.

[0046] During use, when a number of logistics boxes are stacked, they are arranged in a linear array along the three directions of the X-axis, the Y-axis, and the Z-axis, so that the logistics boxes are stacked in a cube shape. A number of support columns 13 in a number of logistics boxes on the same Z-axis are aligned and connected to form a vertical exhaust duct. Under the obstruction of the logistics boxes outside the cube, the hot air inside the cube and the cold air outside are difficult to circulate and contact with each other, so that the temperature inside the cube is higher than the temperature outside. The temperature around the inner logistics box is made higher than the air outside the top logistics box. Under the action of the temperature difference, the hot air around the inner logistics box enters the bottom plate 11 from the air inlet 111, and moves vertically upward from the support column 13, and then moves upward in the corresponding exhaust duct until it is discharged from the top opening of the top support column 13, taking away the heat around the inner logistics box. Under the action of atmospheric pressure, the cold air on the outside of the cube is pressed into the inside of the cube through the gap between adjacent logistics boxes, so that the air on both sides of the cube flows between each other, thereby achieving the purpose of cooling the environment around the inner logistics box, so as to protect the fruits stored in the logistics box and delay the deterioration and corruption of the fruits.

[0047] In this embodiment, a support column 13 is disposed between any two adjacent side panels 12 , and outer walls of the support column 13 are fixedly connected to the two adjacent side panels 12 .

[0048] The bottom plate 11 is rectangular in shape, and four side plates 12 are provided. The four side plates 12 are respectively fixedly connected to the four sides of the bottom plate 11 to form a cubic frame structure with one end open. Four support columns 13 are provided at the four vertices of the bottom plate 11, and the support columns 13 are fixedly connected to two adjacent side plates 12 to improve the structural stability of the logistics box and reduce the probability of the logistics box being squeezed and damaged due to overlapping stacking.

[0049] In this embodiment, the plurality of air inlet holes 111 are all disposed on a side of the bottom plate 11 facing away from the side plate 12 .

[0050] By setting the air inlet 111 on the side of the bottom plate 11 facing away from the side plate 12, the probability of impurities in the logistics box falling into the bottom plate 11 through the air inlet 111 is reduced, so that the inside of the bottom plate 11 and the support column 13 remain unobstructed and heat dissipation work is continuously performed.

[0051] In this embodiment: a groove 132 coaxial with the support column 13 is provided on the opening of one end of the support column 13 facing the bottom plate 11, and the first vent hole 131 radially penetrates through the side wall of the groove 132 and communicates with the inside of the bottom plate 11;

[0052] One end of the support column 13 facing away from the bottom plate 11 protrudes from one side of the side plate 12 facing away from the bottom plate 11, and the end of the support column 13 facing away from the bottom plate 11 is adapted to the groove 132;

[0053] The support column 13 is provided with a second vent hole 133 corresponding to the first vent hole 131 on a portion of the side wall protruding from the side plate 12 .

[0054] During use, when stacking two logistics boxes, place the first logistics box steadily on the ground, lift the second logistics box, and after the four grooves 132 in the four support columns 13 in the second logistics box are aligned with the tops of the four support columns 13 in the first logistics box, put the second logistics box vertically down, so that the tops of the four support columns 13 in the first logistics box are respectively inserted into the four grooves 132 of the four support columns 13 in the second logistics box, thereby limiting the free movement of the second logistics box and the first logistics box in the horizontal direction, reducing the risk of sliding and tipping when the logistics boxes overlap, protecting the safety of relevant technicians, and reducing property losses caused by the tipping of the logistics boxes. The second vent 133 at the top of the support column 13 in the first logistics box is connected to the first vent 131 on the side wall of the groove 132 in the second logistics box, so that the inside of the bottom plate 11 of the two logistics boxes is connected to the exhaust duct, improving the efficiency of heat dissipation around the logistics box.

[0055] In this embodiment: a coaxial mounting ring 21 is provided inside the support column 13, and a support rod 211 is provided outside the mounting ring 21, and one end of the support rod 211 is fixedly connected to the inner wall of the support column 13, and the other end is fixedly connected to the outer wall of the mounting ring 21;

[0056] An impeller 22 is disposed on the side of the mounting ring 21 facing away from the bottom plate 11. The axle of the impeller 22 is a hollow structure with two ends open. One end of the axle of the impeller 22 facing the bottom plate 11 is sleeved outside the mounting ring 21 and rotates coaxially with each other.

[0057] The impeller 22 is connected to a driving unit, and the driving unit is used to drive the impeller 22 to rotate on the mounting ring 21 .

[0058] There are three support rods 211, which are arranged in a circular array with the mounting ring 21 as the center, so that the connection between the mounting ring 21 and the support column 13 is more stable. The hollow space between two adjacent support rods 211 serves as a channel for air flow in the support column 13. The impeller 22 is driven to rotate positively on the mounting ring 21 by the driving unit. The impeller 22 pushes the air to move during the positive rotation, forming an airflow moving toward the top of the support column 13, so that the air in the bottom plate 11 is drawn out, and the hot air around the logistics box is promoted to enter the bottom plate 11 until it is discharged from the top opening of the support column 13, so as to achieve the purpose of cooling the environment around the logistics box, and further improve the efficiency of heat dissipation around the logistics box.

[0059] In this embodiment: the driving part includes a sliding column 23 connected to the mounting ring 21 and slidingly connected along the axial direction of the mounting ring 21, and a rotating sleeve 24 sleeved outside the sliding column 23, and a first spring 25 is disposed outside the mounting ring 21;

[0060] One end of the first spring 25 is fixedly connected to one end of the sliding column 23 facing the bottom plate 11, and the other end is fixedly connected to one end of the mounting ring 21 facing the bottom plate 11, and when the first spring 25 is in a naturally extended state, the end of the sliding column 23 facing the bottom plate 11 is inserted into the groove 132;

[0061] The inner wall of the rotating sleeve 24 is provided with an internal thread, and the rotating sleeve 24 is connected to the sliding column 23 by threaded cooperation. One end of the rotating sleeve 24 facing the bottom plate 11 is embedded in the mounting ring 21 and rotates coaxially, and the other end protrudes outside the mounting ring 21 and is connected to the wheel shaft of the impeller 22.

[0062] During use, when transporting fruits by truck, the fruits are placed in several logistics boxes, and several logistics boxes are stacked on the truck. In two adjacent logistics boxes on the same Y axis, the sliding column 23 in the upper logistics box abuts against the top of the corresponding support column 13 in the lower logistics box under the action of the corresponding first spring 25. When the truck is driving, it is often accompanied by vibration, so that the two adjacent logistics boxes in the same Z axis direction alternate between collision and separation in the vertical direction, and then the support column 13 in the lower logistics box pushes the corresponding sliding column 23 in the upper logistics box to slide on the mounting ring 21, so that the rotating sleeve 24 is pushed to rotate on the mounting ring 21, providing power for the rotation of the impeller 22 on the mounting ring 21, so that the impeller 22 rotates in the forward direction, and promotes the discharge of air around the logistics box.

[0063] In this embodiment, the sliding column 23 is a hollow structure with openings at both ends.

[0064] By setting the sliding column 23 as a hollow structure with openings at both ends, when the two logistics boxes overlap, the top opening plane of the support column 13 in the first logistics box is abutted against the plane of the groove 132 in the second logistics box facing away from the bottom plate 11. Under the action of the first spring 25 in the second logistics box, the corresponding bottom opening plane of the sliding column 23 is in contact with the top opening plane of the support column 13 in the first logistics box, and they are connected to each other, thereby increasing the channel for air flow between the two support columns 13 and reducing the obstruction of the sliding column 23 to the air flow in the support column 13.

[0065] In this embodiment, a sliding groove 231 extending axially along the mounting ring 21 is formed on the outer wall of the sliding column 23 , a sliding block 26 is slidably fitted in the sliding groove 231 , and one end of the sliding block 26 protrudes out of the sliding groove 231 and is fixedly connected to the mounting ring 21 .

[0066] A sliding groove 231 is provided on the outer wall of the sliding column 23 along the axial direction of the mounting ring 21, and a slider 26 that slides in the sliding groove 231 is fixedly connected to the mounting ring 21 to limit the sliding column 23 from rotating on the mounting ring 21. When the sliding column 23 slides on the mounting ring 21 along the axial direction of the mounting ring 21, the rotating sleeve 24 is pushed to rotate on the mounting ring 21, thereby providing power for the rotation of the impeller 22.

[0067] In this embodiment: the end of the impeller 22 that faces away from the bottom plate 11 is fixedly connected to an internally toothed ratchet 27, and the outer circumferential surface of the rotating sleeve 24 that faces away from the bottom plate 11 is provided with a receiving groove 241;

[0068] A wedge block 242 is radially slidably fitted in the receiving groove 241 along the rotating sleeve 24, and a second spring 243 is provided on the wedge block 242. One end of the second spring 243 is fixedly connected to one end of the wedge block 242 facing the receiving groove 241, and the other end is fixedly connected to a plane in the receiving groove 241 that is away from the opening, and when the second spring 243 is in a naturally extended state, the wedge block 242 is inserted into the tooth groove of the internal tooth ratchet 27.

[0069] During use, when the sliding column 23 is pushed away from the base plate 11, the first spring 25 is squeezed and contracted to store energy, and the external thread on the sliding column 23 pushes the rotating sleeve 24 to rotate forward. The wedge block 242 on the rotating sleeve 24 is inserted into the tooth groove of the internal tooth ratchet 27 under the action of the second spring 243, and abuts against the internal tooth ratchet 27 to form a clamping state, pushing the internal tooth ratchet 27 to rotate forward together, and the forward rotation of the impeller 22 generates an upward airflow, which promotes the heat dissipation of the air around the logistics box.

[0070] When the first spring 25 freely extends and releases energy, the sliding column 23 is pushed close to the bottom plate 11, causing the rotating sleeve 24 and the wedge block 242 on the rotating sleeve 24 to rotate in the opposite direction, and the teeth of the internal-toothed ratchet 27 abut against the upper inclined surface of the end of the wedge block 242 facing away from the receiving groove 241, so that the wedge block 242 is squeezed and pushed into the receiving groove 241, and then the wedge block 242 slides smoothly over the teeth of the internal-toothed ratchet 27, so that the internal-toothed ratchet 27 does not rotate in the opposite direction with the rotating sleeve 24, and does not push the air to move.

[0071] That is, when the truck is transporting the logistics box, under the action of vibration, the impeller 22 in the logistics box makes positive intermittent rotation, so that the impeller 22 always pushes the air in the support column 13 to move upward, promoting the heat dissipation of the environment around the fruit in the logistics box.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
