Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable harvesting and transportation technology, specifically to a fresh-keeping transportation vehicle for fruit and vegetable harvesting. Background Technology

[0002] In regions with high summer temperatures, post-harvest preservation of outdoor-grown fruits and vegetables is a crucial step, directly impacting their quality and sales. Currently, due to limitations, harvested outdoor fruits and vegetables cannot be immediately transported to cold storage. They are typically packed in vegetable crates or styrofoam boxes and temporarily stored in the field, with only simple moisturizing measures like covering with cotton cloth and spraying water. After harvesting, they are transported in bulk. However, in hot weather, especially during the dog days of summer, outdoor temperatures are high, leading to significant water evaporation from the fruits and vegetables. This method of moisturizing is clearly insufficient. Furthermore, fruits and vegetables are still living organisms after harvest; in hot and humid environments, transpiration accelerates their physiological activities, especially for leafy green vegetables, which are prone to dehydration, wilting, and loss of vitality. Utility Model Content

[0003] In view of this, it is necessary to provide a fresh-keeping transport vehicle for harvesting fruits and vegetables to solve the technical problems existing in the prior art, such as the inconvenience of storing fruits and vegetables harvested outdoors in the high temperature of summer, the inability to keep them fresh in time, and the resulting dehydration of fruits and vegetables.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A fruit and vegetable harvesting and preservation transport vehicle includes a movable transport compartment, which is a closed compartment on all sides. A door that can be opened or closed is provided at the rear end or one side of the compartment. A partition is horizontally arranged near the top of the transport compartment, dividing the compartment into an upper compartment and a lower compartment. The lower compartment is used to store the harvested fruits and vegetables, and the upper compartment contains a preservation medium. The partition has through holes, through which the preservation medium cools and humidifies the lower compartment to preserve the stored fruits and vegetables.

[0006] Preferably, the lower compartment is provided with a multi-layered support rack for placing fruits and vegetables, which is spaced apart along the height of the lower compartment.

[0007] Preferably, there are multiple compartment doors, which are spaced apart along the height direction of the transfer car. The compartment doors are downward-opening, and each compartment door has a traction belt at both ends that connects to the side wall of the transfer car. After the compartment door is opened downward, it is pulled by the traction belt to keep the compartment door in a parallel state and flush with the bearing surface of each layer of the support frame.

[0008] Preferably, the two opposite ends of the partition are inclined downwards, and the middle part is raised upwards to form an inverted V-shaped plate. The through holes on the partition are strip holes, which are opened along the middle part of the protrusion of the partition towards the two inclined ends.

[0009] Preferably, a flow channel is longitudinally provided on the inner side wall of the transfer carriage. The upper end of the flow channel is connected to the upper compartment, and the lower end is connected to the lower compartment and leads directly to the bottom of the lower compartment.

[0010] Preferably, the top of the transfer compartment is provided with a movable door for easy addition of preservation medium; the bottom of the transfer compartment is provided with a water collection tank, which is connected to the lower compartment, and a drain outlet connected to the outside is provided at the bottom of the water collection tank.

[0012] Preferably, the support frame is a flatbed conveyor, which is arranged in parallel in the lower compartment and multiple sets are arranged at intervals along the height direction of the lower compartment, and the conveying direction of each set of flatbed conveyors is directly opposite each compartment door.

[0013] Preferably, each set of the flat conveyor includes a support frame, a conveyor belt, drive rollers, idlers, and a drive handle. The support frame is arranged parallel to each other in the lower compartment. There are two drive rollers, which are arranged laterally at both ends of the support frame, parallel and aligned with each other. The conveyor belt is looped around the two drive rollers, and the conveying direction of the conveyor belt is facing the door. There are several idlers, which are rotatably spaced on the support frame and located between the two drive rollers, parallel and aligned with each other. The idlers are located directly below the bearing surface of the conveyor belt to support it. The drive handle is rotatably mounted on the outer wall of one side of the transfer car. The shaft of the drive handle passes through the outer wall of the transfer car and extends into the lower compartment of the transfer car, and is fixedly connected to the shaft end of one of the drive rollers. By rotating the drive roller with the drive handle, the conveyor belt is driven to move towards the door or towards the inside of the lower compartment.

[0014] Preferably, the outer wall of the transfer carriage is provided with a locking disc facing the drive handle. The locking disc has a plurality of locking holes around the circumference of the drive handle. The drive handle has a socket that matches the locking holes.

[0022] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] Please refer to Figures 1 to 4 This utility model provides a fresh-keeping transport vehicle for fruit and vegetable harvesting, including a movable transport compartment 1. The transport compartment 1 is a closed compartment on all four sides. The top, bottom and four side walls of the compartment are made of insulation board. The rear end or one side of the compartment is provided with a door 4 that can be opened or closed. The lower end of the compartment is equipped with wheels 2, and the front end of the compartment is equipped with a towing frame 3. When harvesting, the transport compartment 1 can be pulled to the field by connecting the towing frame 3 with a tractor or towing vehicle to facilitate the harvesting and storage of fruits and vegetables. A partition 5 is horizontally installed near the top of the transfer compartment 1, dividing the compartment into an upper compartment 7 and a lower compartment 8. The lower compartment 8 is used to store the harvested fruits and vegetables, while the upper compartment 7 is used to store the preservation medium. The partition 5 is a metal plate with heat-conducting properties and has through holes 6 that are opened vertically to connect the upper compartment 7 and the lower compartment 8. A movable door 13 connected to the upper compartment 7 is installed at the top of the transfer compartment 1. The preservation medium is ice. When in use, the movable door 13 can be opened to put the ice into the upper compartment 7. The ice can cool the lower compartment 8 through the partition 5 and the through holes 6. During use, the water vapor from the melting ice will also enter the lower compartment 8 through the through holes 6, which will humidify the lower compartment 8 and preserve the harvested fruits and vegetables.

[0024] This refrigerated transport vehicle features a closed compartment that isolates it from the outside environment. Ice is used to cool and humidify the interior, providing suitable storage conditions for harvested fruits and vegetables. It can be towed to fields to allow for close contact with the harvested produce, enabling direct storage and reducing outdoor exposure time, thus slowing dehydration and improving quality. Furthermore, the vehicle has a transfer function, allowing for direct transport of harvested fruits and vegetables to cold storage, avoiding the hassle of secondary transfers or loading, providing convenience, speed, and reduced transport losses.

[0025] Please refer to Figure 2 and Figure 4Furthermore, to facilitate the storage of harvested fruits and vegetables, a multi-layered support rack 9 is installed parallel to the lower compartment 8 for placing fruits and vegetables. The support rack 9 is spaced apart along the height of the lower compartment 8. The harvested fruits and vegetables, along with the harvesting frame, can be placed layer by layer on each support rack 9. The support rack 9 is used to store fruits and vegetables in layers, avoiding compression and aggregation. In addition, to reduce the loss of cold air and moisture in the lower compartment 8, the compartment door 4 is set in a split manner, that is, it is set as multiple independent compartment doors 4. The compartment doors 4 are spaced apart along the height of the lower compartment 8 and correspond to the height of each layer of support rack 9. When storing fruits and vegetables, the compartment door 4 corresponding to each support rack 9 can be opened individually, which can reduce the contact area between the lower compartment 8 and the outside air, reduce the loss of cold air and moisture in the lower compartment 8, and reduce the impact of high-temperature outside air on the temperature and humidity in the lower compartment 8.

[0026] Please refer to Figure 2 The compartment doors 4 are designed to flip down and are hinged to the side walls of the transfer compartment 1. Each compartment door 4 has a traction strap 10 at both ends, which is connected to the side wall of the transfer compartment 1. The traction strap 10 is a chain or rope. When the compartment door 4 is flipped open, it is pulled by the traction strap 10 to keep the compartment door 4 parallel to the outside of the transfer compartment 1, forming a support platform that is flush with the bearing surface of each layer of the support rack 9, so that the fruit and vegetable picking frames can be placed into the corresponding support rack 9. Door bolts 11 are provided on the side walls of the compartment at both ends of the compartment door 4, corresponding to each compartment door 4. After the compartment door 4 is closed, it can be locked by the door bolts 11.

[0027] Please refer to Figure 3Furthermore, the two ends of the partition 5 are inclined downwards, and the middle part is raised upwards to form an inverted V-shaped plate. The through hole 6 on the partition 5 is a strip hole. The strip hole is opened along the raised middle part of the partition 5 towards the two inclined ends, and the end of the strip hole is close to or in contact with the inner wall of the transfer car 1. A drainage channel 12 is longitudinally arranged on the inner wall of the transfer car 1. The upper end of the drainage channel 12 is connected to the upper compartment 7, and its lower end is connected to the lower compartment 8 and leads directly to the bottom of the lower compartment 8. In this way, the ice blocks placed on the partition 5 can slide along the inclined surface of the partition 5 to both sides of the upper compartment 7 and approach the drainage channel 12. The cold air released by the ice blocks can enter the lower compartment 8 along the drainage channel 12. The drainage channel 12 can accelerate the air convection in the upper compartment 7 and the lower compartment 8. Furthermore, the through holes 6 are opened at both ends at an inclined direction, which has a guiding function. This allows the water after the ice blocks melt to slide along the edge of the through holes 6 to the inner wall of the transfer compartment 1, so that the water flows into the bottom of the lower compartment 8 along the inner wall of the transfer compartment 1, thus preventing the water droplets from the melting ice blocks from falling on the fruits and vegetables. A water collection tank 14 is provided at the bottom of the transfer compartment 1. The water collection tank 14 is connected to the lower compartment 8. The water collection tank 14 can be used to add water to humidify the lower compartment 8, and can also be used to collect water after the ice melts. A drain outlet 15 connected to the outside is also provided at the bottom of the water collection tank 14. A water valve is provided on the drain outlet 15 to facilitate the discharge of water from the water collection tank 14.

[0028] In this embodiment, the preservation medium can also be a cold storage bag. The frozen cold storage bag is used to cool the lower compartment 8, and the water collection tank 14 is used to add clean water to humidify the lower compartment 8 in order to preserve the stored fruits and vegetables.

[0029] Please refer to Figure 2 , Figure 4 and Figure 5 In a preferred embodiment, to facilitate the placement or removal of fruits and vegetables from the lower compartment 8, the support frame 9 can be replaced with a flat conveyor. The flat conveyor is arranged parallel to the lower compartment 8, and multiple sets are spaced apart along the height of the lower compartment 8. The conveying direction of each set of flat conveyors is directly opposite each compartment door 4. Using the flat conveyor as the support frame 9, it is convenient to transport the harvested fruits and vegetables to the inside of the lower compartment 8, and also convenient to remove them from the lower compartment 8.

[0030] Specifically, each set of flat conveyors includes a support frame 91, a conveyor belt 92, drive rollers 93, idler rollers 94, and a drive handle 95. The support frame 91 is arranged parallel to each other in the lower compartment 8. There are two drive rollers 93, which are arranged laterally at both ends of the support frame 91, parallel and aligned with each other. The conveyor belt 92 is looped around the two drive rollers 93, and the conveying direction of the conveyor belt 92 is facing the door 4. There are several idler rollers 94, which are rotatably spaced on the support frame 91 and located between the two drive rollers 93, parallel and aligned with each other. The idler rollers 94 are located directly below the bearing surface of the conveyor belt 92 to support the conveyor belt 92. The drive handle 95 is a crank handle or handwheel, which is rotatably mounted on the outer wall of one side of the transfer car 1. The shaft of the drive handle 95 passes through the outer wall of the transfer car 1 and extends... The fruit and vegetables are placed in the lower compartment 8 of the transfer car 1 and fixedly connected to the shaft end of one of the drive rollers 93. By turning the drive handle 95, the conveyor belt 92 can be driven to run. When storing fruits and vegetables, the staff opens the door 4 corresponding to each set of flat conveyors in sequence, puts the picking frame of the fruit and vegetables to be stored on the conveyor belt 92, and pushes it to the inside of the lower compartment 8. The conveyor belt 92 will adapt to the direction of the inside of the lower compartment 8 under the pushing force of the picking frame. Alternatively, the staff can manually turn the drive handle 95 to rotate the drive roller 93, thereby driving the conveyor belt 92 to run to the inside of the lower compartment 8 to transport the picking frame of the fruit and vegetables to the lower compartment 8 for storage. When taking out the fruit and vegetables, the staff manually turns the drive handle 95 in the opposite direction to drive the conveyor belt 92 to run towards the door 4, thereby transporting the stored fruit and vegetables to the door 4 for easy removal.

[0031] Please continue reading. Figure 2 To prevent the conveyor belt 92 from rotating under inertial force, a locking disc 16 is provided on the outer wall of the transfer carriage 1, which is directly opposite the drive handle 95. Several locking holes 17 are formed around the circumference of the drive handle 95 on the locking disc 16. The drive handle 95 is provided with a socket 96 that matches the locking holes 17. A detachable pin 97 is inserted into the socket 96. When the drive handle 95 rotates, the socket 96 on the drive handle 95 can coincide with any of the locking holes 17. When the conveyor belt 92 has reached its position, the rotation angle of the drive handle 95 is adjusted again so that the socket 96 on the drive handle 95 coincides with the nearest locking hole 17. Then, the pin 97 is inserted into the corresponding locking hole 17 along the socket 96 to lock the drive handle 95 and prevent the conveyor belt 92 from rotating.

[0032] This refrigerated transport vehicle uses a closed compartment to isolate itself from the outside world. Ice is used to cool and humidify the lower compartment. During harvesting, it can be towed to the field by tractor or tractor-trailer to provide close contact with the harvested fruits and vegetables, providing suitable storage conditions, shortening the time the fruits and vegetables are exposed outdoors, reducing the rate of dehydration, and improving the quality of the fruits and vegetables. After harvesting, it can be directly transported to the cold storage by tractor or tractor-trailer, avoiding the trouble of secondary transfer or loading, making it convenient and fast, and reducing transfer losses.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
