Description

Technical Field

[0001] The invention relates to the technical field of storage devices, and in particular to a transport and storage device and method for agricultural and sideline products. Background Art

[0002] As an agricultural and sideline product, bananas need to maintain their appearance and taste during long-distance transportation (from production area to sales area) to ensure that their value does not drop.

[0003] As a fruit, bananas are prone to blackening and rotting at the squeezed part after being squeezed locally, which seriously affects the sales of bananas. However, during the transportation of bananas, when the vehicle brakes or accelerates, the banana bunches will inevitably move relative to the side wall of the packaging box, which will cause the local surface of the bananas to be compressed.

[0004] like Fig.13 As shown in the figure, after being picked, bananas are usually in the form of banana bunches. At present, when transporting bananas, they are usually wrapped in several layers of plastic film and placed in packaging boxes, and then loaded into refrigerated compartments. During the transportation process, the bananas at the bottom are easily damaged by excessive pressure. How to effectively utilize the loading space and reduce the external force damage of bananas during the transportation process is a problem that needs to be faced;

[0005] To this end, a transport and storage device and method for agricultural and sideline products are proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a transport and storage device and method for agricultural and sideline products, so as to solve the problem of how to effectively utilize the loading space and reduce the external force damage of bananas during the transport process proposed in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: a transport and storage device for agricultural and sideline products, comprising a storage box, a hanging mechanism for hanging banana bunches is installed on the internal top wall of the storage box, a flexible fixing mechanism for supporting the banana bunches laterally is installed on the upper part of the inner side wall of the storage box, a protection mechanism is installed on the lower part of the inner side wall of the storage box, an adjustment mechanism is installed on the inner bottom wall of the storage box, a box door is installed on the front surface of the storage box, and ventilation holes are evenly opened on both sides of the outer side wall of the storage box;

[0008] The hanging mechanism comprises a steel wire rope, which is located above the interior of the storage box, and a sharp-mouthed hook is fixedly connected to the bottom end of the steel wire rope, and the banana bunch can be hung on the sharp-mouthed hook;

[0009] The flexible fixing mechanism comprises two fixed cylinders, which are respectively fixedly mounted on both sides of the inner wall of the storage box, one end of the output shaft of the fixed cylinder is fixedly connected with a mounting plate, and an airbag assembly is mounted on the inner wall of the mounting plate;

[0010] When the storage box is placed in the refrigerated truck, the axis of the fixed cylinder is parallel to the axis of the refrigerated truck. When the refrigerated truck accelerates or decelerates, the airbag assemblies on the front and rear sides can be inflated or deflated respectively to prevent excessive squeezing of the clamping airbag and the banana bunch.

[0011] The present invention can significantly reduce local or overall squeezing of banana bunches by hanging banana bunches and flexibly clamping and supporting the banana bunches during the transportation and storage process, thereby protecting bananas during transportation, reducing losses during transportation of bananas, and increasing economic benefits.

[0012] Preferably, the airbag assembly includes clamping airbag one, clamping airbag two and clamping airbag three which are fixedly connected to the mounting plate from top to bottom in sequence. Clamping airbag one, clamping airbag two and clamping airbag three are semi-annular, and connecting pipes are connected between the opposite sides of clamping airbag one and clamping airbag two, and between the opposite sides of clamping airbag two and clamping airbag three.

[0013] Under the above configuration, after the banana bunch is hung by the hanging mechanism, in order to prevent the banana bunch from swinging greatly and to provide lateral support, and to relieve the hanging force on the top of the banana bunch, the present invention provides a multi-layer airbag assembly for providing buffering and lateral support.

[0014] Preferably, the protection mechanism includes a slide plate, which is parallel to the fixed cylinder, and the two ends of the slide plate are respectively fixedly connected to the lower part of the inner wall of the storage box, the outer wall of the slide plate is slidably connected to a sliding seat, and the top of the sliding seat is fixedly connected to a counterweight seat, and two air cylinders are symmetrically fixedly connected to the lower part of the inner wall of the storage box, and the inner wall of the air cylinder is slidably connected to a piston plate, and the side of the piston plate close to the counterweight seat is fixedly connected to a sliding rod, the sliding rod is slidably connected to the air cylinder, and one end of the sliding rod close to the counterweight seat is fixedly connected to the counterweight seat, an air guide tube 1 is connected between the upper surface of the air cylinder close to the counterweight seat and the lower surface of the clamping airbag three, and the rear surface of the air cylinder is connected to an air guide tube 2 for gas compensation in the air cylinder.

[0015] Preferably, the front surfaces of the clamping airbag 1, the clamping airbag 2 and the clamping airbag 3 are all provided with air nozzles for inflation or deflation.

[0016] Under the above settings, in order to avoid the problem that "due to inertia, the banana bunch will squeeze the side wall of the packaging box, which may easily cause the bananas on the side to be compressed and damaged" the present invention provides a protection mechanism. When the protection mechanism is working, such as in the braking situation, the counterweight seat slides forward due to inertia during braking, and the counterweight seat pushes the front piston plate forward through the sliding rod, and pulls the rear piston plate forward. The front air cylinder will be in a negative pressure state and extract the air in the front clamping airbag, reducing the squeezing force between the front airbag assembly and the banana bunch, while the rear air cylinder will be in a positive pressure state and push the gas into the rear clamping airbag, so that the rear airbag assembly and the banana bunch remain in contact, and continue to play an auxiliary support role.

[0017] Preferably, the suspension mechanism also includes two vertical plates and a lifting motor. The tops of the two vertical plates are symmetrically fixedly connected to the inner top wall of the storage box. A horizontal plate is fixedly connected to the top of the inner right wall of the storage box. The lifting motor is installed on the upper surface of the horizontal plate. A limiting rod is fixedly connected to the left side of the upper surface of the horizontal plate. The interior of the connecting tube is hollow and narrow.

[0018] Under this setting, the hanging height of the banana string can be adjusted by the rotation of the lifting motor. Because the hanging mechanism in the present invention is in a fixed position, after the hanging mechanism lifts the banana string, the banana string will swing around the limit ring when it shakes. At this time, the swing range of the bottom of the banana string will be the largest. The present invention will limit the diameter of the connecting pipe to make the diameter of the connecting pipe narrow, increase the delay of the gas flow between each clamping airbag, so the deformation of the clamping airbag three is the largest, the deformation of the clamping airbag two is second, and the deformation of the clamping airbag one is the smallest, which just meets the swing state of the banana string during braking, preventing the bananas at the bottom from being excessively squeezed due to the large swing amplitude, further effectively reducing the squeezing force on the banana string during braking, and providing protection for the bananas;

[0019] Preferably, the suspension mechanism also includes two vertical plates and a lifting motor, two fixed shafts are symmetrically fixedly connected to the top of the inner wall of the storage box, a movable plate is slidably connected to the outer wall of the fixed shaft, a spring is fixedly connected between the movable plate and the opposite side of the storage box, the top of the two vertical plates are symmetrically fixedly connected to the lower surface of the movable plate, the lifting motor is installed on the right side of the lower surface of the movable plate, a limiting rod is fixedly connected to the lower surface of one of the vertical plates, and the interior of the connecting tube is hollow and wide.

[0020] In this setting, the banana string suspension height can be adjusted by the rotation of the lifting motor. The suspension mechanism in the present invention is in a horizontally movable state. When the banana string shakes due to the change in vehicle speed, it tends to move horizontally. At this time, the horizontal movement of the suspension mechanism can directly compensate for the position. At this time, the inside of the connecting tube is hollow and wide, in order to increase the consistency of the inflation and deflation of the airbag assembly at the upper and lower positions, and play a role of uniform buffering and side support.

[0021] Preferably, the opposite sides of the two vertical plates are rotatably connected to a rotating shaft through a bearing, a reel is fixedly connected between the opposite sides of the two rotating shafts, the wire rope is wrapped around the outer wall of the reel, the right end of the rotating shaft passes through the right side wall of the vertical plate and is fixedly connected to one end of the output shaft of the lifting motor, the left end of the limit rod is fixedly connected to the limit ring, and the wire rope passes through the limit ring.

[0022] Preferably, the adjustment mechanism includes an adjusting cylinder, the bottom of which is fixedly connected to the inner bottom wall of the storage box, one end of the piston rod of the adjusting cylinder is fixedly connected to a lifting plate, a roller is installed on the lower surface of the slide seat, the roller rolls on the upper surface of the lifting plate, a rubber layer for increasing friction is fixedly connected to the upper surface of the lifting plate, and two sleeve rods are symmetrically fixedly connected to the lower surface of the lifting plate.

[0023] Preferably, the inner bottom wall of the storage box is symmetrically fixedly connected with two sleeves, and the outer side wall of the sleeve rod is slidably connected to the inner side wall of the sleeve.

[0024] Under the above settings, when facing different types of banana bunches, the diameters of the banana bunches vary greatly. At this time, the amount of air required to be inflated or deflated in the airbag assembly will be different. The present invention can change the amount of gas compensation in the protection mechanism according to the size of the banana bunch. When the counterweight seat slides forward due to inertia during braking, it will drive the slide seat to move forward synchronously, and then drive the roller to roll forward. The roller will be subject to the friction force from the upper surface of the lifting plate. The greater the friction force, the smaller the movement amplitude of the counterweight seat, the smaller the stroke of the piston plate, and the greater the deformation of each clamping airbag. The smaller the friction force is, the greater the movement of the counterweight seat is, the greater the stroke of the piston plate is, and the greater the deformation of each clamping airbag is. Therefore, by adjusting the extension and retraction of one end of the piston rod of the cylinder to make the lifting plate move up and down, the friction force of the lifting plate on the roller can be adjusted. If the banana string is heavier, the banana string will have a larger amplitude when braking. At this time, the deformation of the clamping airbag needs to be increased to make the adjustment cylinder control the lifting plate to move downward. If the banana string is lighter, the banana string will swing less when braking. At this time, the deformation of the clamping airbag needs to be reduced to make the adjustment cylinder control the lifting plate to move up.

[0025] Preferably, a fresh-keeping mechanism is installed on one side of the interior of the storage box, and the fresh-keeping mechanism includes a supporting plate, the left side wall of the supporting plate is fixedly connected to the inner left side wall of the storage box, and a placement box is fixedly connected to the upper surface of the supporting plate. The placement box contains bagged ethylene absorbent, and a sealing patch is adhered to the top of the placement box.

[0026] The method for using the transport and storage device for agricultural and sideline products comprises the following steps:

[0027] S1, banana installation, by shortening one end of the piston rod of the fixed cylinder, driving the two mounting plates away from each other, and hanging the banana string on the sharp hook;

[0028] S2, banana side support, by extending one end of the piston rod of the fixed cylinder to drive the two mounting plates closer to each other, so that the clamping airbags 1, 2 and 3 on both sides are close to each other, and the banana bunch is flexibly clamped and fixed;

[0029] S3, preservation, after hanging the banana bunches, tear off the sealing patch to expose the bagged ethylene absorbent to the air inside the storage box;

[0030] S4, transfer protection. During braking and deceleration, the counterweight seat slides forward due to inertia. The counterweight seat pushes the front piston plate through the sliding rod and pulls the rear piston plate. The front air cylinder will be in a negative pressure state and extract the air in the front airbag assembly, reducing the squeezing force between the front airbag assembly and the banana string. The rear air cylinder will be in a positive pressure state and push the gas into the rear airbag assembly, so that the rear airbag assembly and the banana string remain in contact and continue to play an auxiliary support role.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention can significantly reduce local or overall squeezing of banana bunches by hanging banana bunches and flexibly clamping and supporting them during the transportation and storage of banana bunches, thereby protecting bananas during transportation, reducing losses during transportation of bananas, and increasing economic benefits. After the banana bunches are hung by the hanging mechanism, in order to prevent the banana bunches from swinging greatly and to provide lateral support and relieve the hanging force on the top of the banana bunches, the present invention is provided with a multi-layer airbag assembly for providing buffering and lateral support.

[0033] 2. The present invention provides a protection mechanism. When the protection mechanism is working, such as when braking, the counterweight seat slides forward due to inertia, and the counterweight seat pushes the front piston plate forward through the slide rod, pulling the rear piston plate forward. The front air cylinder will be in a negative pressure state and extract the air in the front clamping airbag, reducing the squeezing force between the front airbag assembly and the banana string, while the rear air cylinder will be in a positive pressure state and push the gas into the rear clamping airbag, so that the rear airbag assembly and the banana string remain in contact, and continue to play an auxiliary support role.

[0034] 3. The present invention can adjust the hanging height of the banana bunch by rotating the lifting motor. Because the hanging mechanism in the present invention is in a fixed position, after the hanging mechanism lifts the banana bunch, the banana bunch will swing around the limit ring when it shakes. At this time, the swing range of the bottom of the banana bunch will be the largest. The present invention will limit the caliber of the connecting pipe to narrow the caliber of the connecting pipe and increase the delay of the gas flow between each clamping airbag. Therefore, the deformation of the clamping airbag three is the largest, the deformation of the clamping airbag two is second, and the deformation of the clamping airbag one is the smallest, which just meets the swinging state of the banana bunch during braking, preventing the bananas at the bottom from being excessively squeezed due to the large swing amplitude, further effectively reducing the squeezing force on the banana bunch during braking, and providing protection for the bananas.

[0035] 4. When the present invention faces different types of banana strings, the diameters of the banana strings vary greatly. At this time, the amount of air required to be inflated or deflated in the airbag assembly will be different. The present invention can change the amount of gas compensation in the protection mechanism according to the size of the banana string. When the counterweight seat slides forward due to inertia during braking, it will drive the slide seat to move forward synchronously, and then drive the roller to roll forward. The roller will be subject to the friction force from the upper surface of the lifting plate. The greater the friction force, the smaller the movement of the counterweight seat, the smaller the stroke of the piston plate, and the smaller the deformation of each clamping airbag. Conversely, the greater the friction force, the smaller the movement of the counterweight seat, and the smaller the deformation of each clamping airbag. The smaller it is, the greater the movement amplitude of the counterweight seat is, the greater the stroke of the piston plate is, and the greater the deformation of each clamping airbag is. Therefore, by adjusting the extension and retraction of one end of the piston rod of the cylinder to make the lifting plate move up and down, the friction force of the lifting plate on the roller can be adjusted. If the banana bunch is heavier, the banana bunch will have a larger amplitude when braking. At this time, the deformation of the clamping airbag needs to be increased, so that the adjustment cylinder can control the lifting plate to move downward. If the banana bunch is lighter, the banana bunch will swing less when braking. At this time, the deformation of the clamping airbag needs to be reduced, so that the adjustment cylinder can control the lifting plate to move up, which can adapt to banana bunches of different sizes.

[0056] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as limitations on the present application.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0057] Example 1

[0058] See also Figure 1-10 and Fig.13 The present invention provides a technical solution: a transport and storage device for agricultural and sideline products, comprising a storage box 1, a hanging mechanism 2 for hanging banana bunches is installed on the internal top wall of the storage box 1, a flexible fixing mechanism 3 for supporting the banana bunches laterally is installed on the upper part of the inner side wall of the storage box 1, a protection mechanism 4 is installed on the lower part of the inner side wall of the storage box 1, an adjustment mechanism 5 is installed on the inner bottom wall of the storage box 1, a box door 7 is installed on the front surface of the storage box 1, and ventilation holes 8 are evenly opened on both sides of the outer side wall of the storage box 1;

[0059] The hanging mechanism 2 includes a steel wire rope 24, which is located above the interior of the storage box 1. The bottom end of the steel wire rope 24 is fixedly connected with a sharp hook 25, and the banana bunch can be hung on the sharp hook 25;

[0060] The flexible fixing mechanism 3 includes two fixed cylinders 31, which are respectively fixedly mounted on both sides of the inner wall of the storage box 1, and one end of the output shaft of the fixed cylinder 31 is fixedly connected to a mounting plate 32, and an airbag assembly is mounted on the inner wall of the mounting plate 32;

[0061] When the storage box 1 is placed in a refrigerated truck, the axial direction of the fixed cylinder 31 is parallel to the axial direction of the refrigerated truck. When the refrigerated truck accelerates or decelerates, the air bag assemblies on the front and rear sides can be inflated or deflated respectively to prevent excessive squeezing of the clamping air bag and the banana bunch.

[0062] The present invention can significantly reduce local or overall squeezing of banana bunches by hanging banana bunches and flexibly clamping and supporting the banana bunches during the transportation and storage process, thereby protecting bananas during transportation, reducing losses during transportation of bananas, and increasing economic benefits.

[0063] In the present embodiment, specifically, the airbag assembly includes a clamping airbag 1 33, a clamping airbag 2 34 and a clamping airbag 3 35 which are fixedly connected to the mounting plate 32 from top to bottom in sequence. The clamping airbag 1 33, the clamping airbag 2 34 and the clamping airbag 3 35 are semi-annular, and connecting pipes 36 are connected between the opposite sides of the clamping airbag 1 33 and the clamping airbag 2 34, and between the opposite sides of the clamping airbag 2 34 and the clamping airbag 3 35.

[0064] Under the above configuration, after the banana bunch is hung by the hanging mechanism 2, in order to prevent the banana bunch from swinging greatly and to provide lateral support and relieve the hanging force on the top of the banana bunch, the present invention provides a multi-layer airbag assembly for providing buffering and lateral support.

[0065] In the present embodiment, specifically, the protection mechanism 4 comprises a slide plate 41, the slide plate 41 is parallel to the fixed cylinder 31, the two ends of the slide plate 41 are respectively fixedly connected to the lower part of the inner wall of the storage box 1, the outer wall of the slide plate 41 is slidably connected with a slide seat 42, the top of the slide seat 42 is fixedly connected with a counterweight seat 43, the lower part of the inner wall of the storage box 1 is symmetrically fixedly connected with two air cylinders 44, the inner wall of the air cylinder 44 is slidably connected with a piston plate 45, the side of the piston plate 45 close to the counterweight seat 43 is fixedly connected with a slide rod 46, the slide rod 46 is slidably connected to the air cylinder 44, one end of the slide rod 46 close to the counterweight seat 43 is fixedly connected to the counterweight seat 43, an air guide pipe 1 47 is connected between the upper surface of the air cylinder 44 close to the counterweight seat 43 and the lower surface of the clamping airbag 3 35, and the rear surface of the air cylinder 44 is connected with an air guide pipe 2 48 for gas compensation in the air cylinder 44.

[0066] In this embodiment, specifically, the front surfaces of the clamping airbag 1 33 , the clamping airbag 2 34 , and the clamping airbag 3 35 are all provided with air nozzles 37 for inflation or deflation.

[0067] Under the above arrangement, in order to avoid the problem that "due to inertia, the banana bunch will squeeze the side wall of the packaging box, which may easily cause the bananas on the side to be compressed and damaged" the present invention provides a protection mechanism 4. When the protection mechanism 4 is working, such as in the braking situation, the counterweight seat 43 slides forward due to inertia during braking, and the counterweight seat 43 pushes the front piston plate 45 forward through the slide rod 46, and pulls the rear piston plate 45 forward. The front air cylinder 44 will be in a negative pressure state and extract the air in the front clamping airbag, reducing the squeezing force between the front airbag assembly and the banana bunch, while the rear air cylinder 44 will be in a positive pressure state and push the gas into the rear clamping airbag, so that the rear airbag assembly and the banana bunch remain in contact, and continue to play an auxiliary support role.

[0068] In the present embodiment, specifically, the suspension mechanism 2 further comprises two vertical plates 21 and a lifting motor 27. The tops of the two vertical plates 21 are symmetrically fixedly connected to the inner top wall of the storage box 1. A horizontal plate 26 is fixedly connected to the top of the inner right wall of the storage box 1. The lifting motor 27 is mounted on the upper surface of the horizontal plate 26. A limiting rod 28 is fixedly connected to the left side of the upper surface of the horizontal plate 26. The interior of the connecting tube 36 is hollow and narrow.

[0069] In the present embodiment, specifically, the opposite sides of the two vertical plates 21 are rotatably connected with the rotating shaft 22 through bearings, a reel 23 is fixedly connected between the opposite sides of the two rotating shafts 22, the wire rope 24 is wound around the outer wall of the reel 23, the right end of the rotating shaft 22 passes through the right side wall of the vertical plate 21 and is fixedly connected to one end of the output shaft of the lifting motor 27, the left end of the limit rod 28 is fixedly connected to the limit ring 29, and the wire rope 24 passes through the limit ring 29.

[0070] Under this setting, the hanging height of the banana string can be adjusted by the rotation of the lifting motor 27. Because the hanging mechanism 2 in the present invention is in a fixed position, after the hanging mechanism 2 hangs up the banana string, when the banana string shakes, it will swing around the limit ring 29 as the center. At this time, the swing range of the bottom of the banana string will be the largest. The present invention will limit the diameter of the connecting tube 36 to make the diameter of the connecting tube 36 narrow, increase the delay of the gas flow between each clamping airbag, so the deformation of the clamping airbag three 35 is the largest, the deformation of the clamping airbag two 34 is second, and the deformation of the clamping airbag one 33 is the smallest, which just meets the swinging state of the banana string during braking, preventing the bananas at the bottom from being excessively squeezed due to the large swing amplitude, further effectively reducing the squeezing force on the banana string during braking, and providing protection for the bananas;

[0071] In the present embodiment, specifically, the adjusting mechanism 5 comprises an adjusting cylinder 52, the bottom of which is fixedly connected to the inner bottom wall of the storage box 1, one end of the piston rod of the adjusting cylinder 52 is fixedly connected to a lifting plate 53, a roller 51 is mounted on the lower surface of the slide seat 42, the roller 51 rolls on the upper surface of the lifting plate 53, a rubber layer for increasing friction is fixedly connected to the upper surface of the lifting plate 53, and two sleeve rods 54 are symmetrically fixedly connected to the lower surface of the lifting plate 53.

[0072] In this embodiment, specifically, two sleeves 55 are symmetrically fixedly connected to the inner bottom wall of the storage box 1 , and the outer side wall of the sleeve rod 54 is slidably connected to the inner side wall of the sleeve 55 .

[0073] Under the above settings, when facing different types of banana bunches, the diameters of the banana bunches vary greatly. At this time, the amount of air required to be inflated or deflated in the airbag assembly will be different. The present invention can change the amount of gas compensation in the protection mechanism 4 according to the size of the banana bunch. When the counterweight seat 43 slides forward due to inertia during braking, it will drive the slide seat 42 to move forward synchronously, and then drive the roller 51 to roll forward. The roller 51 will be subjected to the friction force from the upper surface of the lifting plate 53. The greater the friction force, the smaller the movement amplitude of the counterweight seat 43, the smaller the stroke of the piston plate 45, and the smaller the deformation of each clamping airbag. Conversely, the smaller the friction force, the smaller the displacement amplitude of the counterweight seat 43. The greater the movement amplitude of the counterweight seat 43, the greater the stroke of the piston plate 45, and the greater the deformation of each clamping airbag. Therefore, by adjusting the extension and retraction of one end of the piston rod of the cylinder 52, the lifting plate 53 is moved up and down, and the friction force of the lifting plate 53 on the roller 51 can be adjusted. If the banana bunch is heavier, the banana bunch will have a larger amplitude when braking. At this time, the deformation of the clamping airbag needs to be increased, so that the adjusting cylinder 52 controls the lifting plate 53 to move downward. If the banana bunch is lighter, the banana bunch will have a smaller swing amplitude when braking. At this time, the deformation of the clamping airbag needs to be reduced, so that the adjusting cylinder 52 controls the lifting plate 53 to move upward, which can adapt to banana bunches of different sizes.

[0074] In this embodiment, specifically, a preservation mechanism 6 is installed on one side of the interior of the storage box 1. The preservation mechanism 6 includes a bearing plate 61. The left side wall of the bearing plate 61 is fixedly connected to the inner left side wall of the storage box 1. A placement box 62 is fixedly connected to the upper surface of the bearing plate 61. The placement box 62 contains a bagged ethylene absorbent. A sealing patch 63 is adhered to the top of the placement box 62. After the banana bunches are hung, the sealing patch 63 is torn off, so that the bagged ethylene absorbent absorbs the ethylene gas around the bananas to slow down their ripening and aging process.

[0075] Example 2, please refer to Figure 1 , Figure 6 as well as Figure 8-13 The suspension mechanism 2 also includes two vertical plates 21 and a lifting motor 27. Two fixed shafts 210 are symmetrically fixedly connected to the top of the inner wall of the storage box 1. A movable plate 211 is slidably connected to the outer wall of the fixed shaft 210. A spring 212 is fixedly connected between the movable plate 211 and the opposite side of the storage box 1. The tops of the two vertical plates 21 are symmetrically fixedly connected to the lower surface of the movable plate 211. The lifting motor 27 is installed on the right side of the lower surface of the movable plate 211. The lower surface of one of the vertical plates 21 is fixedly connected to a limiting rod 28. The interior of the connecting pipe 36 is hollow and wide.

[0076] Under this setting, the banana string suspension height can be adjusted by the rotation of the lifting motor 27. The suspension mechanism 2 in the present invention is in a horizontally movable state. When the banana string shakes due to the change in vehicle speed, it tends to move horizontally. At this time, the horizontal movement of the suspension mechanism 2 can directly perform position compensation. At this time, the connecting tube 36 is hollow and wide inside to increase the consistency of inflation and deflation of the airbag assembly at the upper and lower positions, and play a role of uniform buffering and side support.

[0077] The lifting motor 27 used in the present invention is a brushless DC motor with a self-locking function, which adopts PWM control and has a feedback control function. It can achieve accurate locking at any angle. Even when there is a power outage or power failure, the lifting motor 27 can maintain its operating position, that is, it has a self-locking function.

[0078] The present invention also provides a method for using the transport and storage device for agricultural and sideline products, comprising the following steps:

[0079] S1, banana installation, by shortening one end of the piston rod of the fixed cylinder 31, driving the two mounting plates 32 away from each other, and hanging the banana bunch on the sharp hook 25;

[0080] S2, banana side support, by extending one end of the piston rod of the fixed cylinder 31 to drive the two mounting plates 32 to move closer to each other, so that the clamping airbags 1 33, 2 34 and 3 35 on both sides move closer to each other, and the banana bunch is flexibly clamped and fixed;

[0081] S3, preservation, after hanging the banana bunches, tear off the sealing patch 63, so that the bagged ethylene absorbent is exposed to the air inside the storage box 1;

[0082] S4, transportation protection. During the braking and deceleration process, the counterweight seat 43 slides forward due to inertia. The counterweight seat 43 pushes the front piston plate 45 through the sliding rod 46 and pulls the rear piston plate 45. The front air cylinder 44 will be in a negative pressure state and extract the air in the front airbag assembly, reducing the squeezing force between the front airbag assembly and the banana string. The rear air cylinder 44 will be in a positive pressure state and push the gas into the rear airbag assembly, so that the rear airbag assembly and the banana string remain in contact and continue to play an auxiliary support role.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
