A refrigerated vegetable transport vehicle

Abstract

This utility model belongs to the field of vegetable transportation technology and provides a refrigerated vegetable transport vehicle, including a refrigerated compartment installed on the transport vehicle. A refrigeration device is installed on one side of the upper part of the refrigerated compartment, and an air supply channel is installed at one end of the refrigeration device. Air inlets are opened on both sides of the lower end of the air supply channel. A reciprocating screw is rotatably connected to one side of the air supply channel, and a first threaded rod is installed on the side of the air supply channel away from the reciprocating screw. This utility model uses a servo motor to drive the first threaded rod and the reciprocating screw to work together to realize the orderly lifting and lowering of the blocking frame, thereby flexibly controlling the opening and closing of the air inlets. This allows the cold air to be delivered in a directional manner as needed. By prioritizing the opening of the air inlets near the depth of the compartment, the vegetables and fruits at the depth are allowed to come into contact with the cold air first, avoiding spoilage caused by temperature lag. Subsequently, the air inlets near the doors are gradually opened as needed to achieve uniform delivery of cold air throughout the entire compartment.

Description

Technical Field

[0001] This utility model relates to the field of vegetable transportation technology, specifically to a refrigerated vegetable transport vehicle. Background Technology

[0002] Refrigerated transport vehicles are specialized transport vehicles equipped with refrigeration systems, primarily used for transporting perishable goods such as fresh foods, vegetables, fruits, and meats that require high temperatures. By regulating the temperature and humidity inside the vehicle, they ensure that goods remain fresh during transportation, extending their shelf life.

[0003] Currently, refrigerated vegetable transport vehicles typically use a continuous circulation system that delivers cold air and absorbs heat to achieve refrigeration. However, the cold air is usually discharged directly from the conveyor frame into the truck bed, resulting in uneven distribution of cold air. Vegetables at the innermost part of the truck bed are exposed to cold air too early, while those at the rear are exposed later, leading to some spoilage. To address these issues, a new type of refrigerated vegetable transport vehicle has been designed. Utility Model Content

[0004] In view of the deficiencies in the existing technology, this utility model provides a refrigerated vegetable transport vehicle to reduce economic losses caused by improper temperature control.

[0005] This utility model provides a refrigerated vegetable transport vehicle, comprising: a refrigerated compartment installed on the transport vehicle; a refrigeration device installed on one side of the upper end of the refrigerated compartment; an air supply channel installed at one end of the refrigeration device; air supply ports on both sides of the lower end of the air supply channel; a reciprocating screw rotatably connected to one side of the air supply channel; a first threaded rod installed on the side of the air supply channel away from the reciprocating screw; a moving block threadedly connected to both the first threaded rod and the reciprocating screw; a rack fixedly connected to the lower end of the moving block; a gear meshing at the front of the rack; a second threaded rod fixedly connected to the lower end of the gear; and a blocking frame threadedly connected to the lower end of the second threaded rod for blocking the air supply ports.

[0006] Optionally, a ventilation net is also fixedly connected to the lower end of the gas transmission channel, and the ventilation net is located in the middle of the gas transmission channel.

[0007] Optionally, the reciprocating lead screw and the first threaded rod are fixedly connected to a mounting rod on one side close to each other.

[0008] Optionally, a servo motor is fixedly connected to one side of the No. 1 threaded rod through the side wall of the gas transmission channel, a support frame is fixedly connected to the lower end of the servo motor, and the end wall of the refrigerated compartment is fixedly connected to the upper end of the support frame.

[0009] Optionally, a rotating rod is fixedly connected to the middle of the upper end of the gear, and the upper end of the rotating rod is rotatably connected to the inner wall of the gas delivery channel.

[0010] Optionally, a bottom support is fixedly installed at the bottom of the refrigerated compartment, and the bottom support has several ventilation holes.

[0011] As can be seen from the above technical solution, the refrigerated vegetable transport vehicle provided by this utility model uses a servo motor to drive the No. 1 threaded rod and the reciprocating screw to work together to achieve orderly lifting and lowering of the blocking frame, thereby flexibly controlling the opening and closing of the air inlet. This allows the cold air to be delivered in a directional manner as needed. First, by prioritizing the opening of the air inlet near the depth of the compartment, the vegetables and fruits at the depth are allowed to come into contact with the cold air first, avoiding spoilage caused by temperature lag. Then, the air inlets near the door are gradually opened as needed to achieve uniform delivery of cold air throughout the compartment. This effectively improves the refrigeration effect and preservation time of vegetables and fruits during transportation, and reduces economic losses caused by improper temperature control.

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a refrigerated vegetable transport vehicle. (Refer to...) Figure 1-3 A refrigerated vegetable transport vehicle includes a refrigerated compartment 1 installed on the transport vehicle. A refrigeration device 15 is installed on one side of the upper end of the refrigeration compartment 1. An air supply channel 2 is installed at one end of the refrigeration device 15. Air supply ports are opened on both sides of the lower end of the air supply channel 2. A reciprocating screw 3 is rotatably connected to one side of the air supply channel 2. A first threaded rod 4 is installed on the side of the air supply channel 2 away from the reciprocating screw 3. A mounting rod 7 is fixedly connected to the reciprocating screw 3 and the first threaded rod 4 on the side close to each other, so that the first threaded rod 4 and the reciprocating screw 3 are connected to each other, which facilitates the simultaneous rotation of the first threaded rod 4 and the reciprocating screw 3.

[0021] The first threaded rod 4 is fixedly connected to the servo motor 5 through the side wall of the gas transmission channel 2. The lower end of the servo motor 5 is fixedly connected to the support frame 6, and the upper end of the support frame 6 is fixedly connected to the end wall of the refrigerated compartment 1. The servo motor 5 can be started, so that the servo motor 5 can drive the first threaded rod 4 and the reciprocating screw 3 to rotate at the same time, reducing the use of equipment and making it easier to control the first threaded rod 4 and the reciprocating screw 3.

[0022] Both the first threaded rod 4 and the reciprocating screw 3 are threadedly connected to the moving block 8. The lower end of the moving block 8 is fixedly connected to the rack 9. The front part of the rack 9 meshes with the gear 10. The lower end of the gear 10 is fixedly connected to the second threaded rod 12. The lower end of the second threaded rod 12 is threadedly connected to the blocking frame 13 for blocking the gas inlet.

[0023] A rotating rod 11 is fixedly connected to the middle of the upper end of the gear 10. The upper end of the rotating rod 11 is rotatably connected to the inner wall of the air supply channel 2. The rotating rod 11 is used to fix the gear 10.

[0024] Start the servo motor 5, which simultaneously drives the first threaded rod 4 and the reciprocating screw 3 to rotate. The reciprocating screw 3 and the first threaded rod 4 both drive the moving block 8 on them to move, which in turn drives the rack 9 to move. The rack 9 drives the gear 10 to rotate, which in turn drives the second threaded rod 12 to rotate. The second threaded rod 12 drives the blocking frame 13 to rise, thus not blocking the air outlet and facilitating the uniform delivery of cold air.

[0025] A ventilation net 14 is also fixedly connected to the lower end of the gas transmission channel 2. The ventilation net 14 is located in the middle of the gas transmission channel 2, so that cold air can be transported from the middle.

[0026] A bottom support 16 is fixedly installed at the bottom of the refrigerated compartment 1, and several ventilation holes are opened on the bottom support 16.

[0027] A method of using a refrigerated vegetable transport vehicle: The servo motor 5 can be started, which simultaneously drives the first threaded rod 4 and the reciprocating screw 3 to rotate. Both the reciprocating screw 3 and the first threaded rod 4 drive the moving block 8 on them to move, which in turn drives the rack 9 to move. The rack 9 drives the gear 10 to rotate, which in turn drives the second threaded rod 12 to rotate. The second threaded rod 12 drives the blocking frame 13 to rise. During this process, the reciprocating screw 3 first drives the blocking frame 13 on it to rise, while the blocking frame 13 on the side of the first threaded rod 4 has not yet risen. That is, when the first threaded rod 4 drives the moving block 8 to move, the rack 9 has not yet meshed with the gear 12 on the same side, but is about to make contact. This opens the air supply channel 3 close to the air supply port in the refrigerated compartment 1, allowing cold air to be directly delivered from the air supply port and the ventilation net 14 into the compartment, so that the vegetables and fruits deep inside come into contact with the cold air first and are cooled quickly.

[0028] When it is necessary to continue opening the air outlet at the door of the compartment so that cold air is delivered from both sides, ensuring that the fruits and vegetables deep inside the compartment and at the door receive cold air and improving the refrigeration effect of the fruits and vegetables at the door, the servo motor 5 can be started again. The first threaded rod 4 and the reciprocating screw 3 continue to rotate. At this time, the moving block 8 on the first threaded rod 4 drives the rack 9 to move, so that the gear 10 drives the second threaded rod 12 to rotate, causing the blocking frame 13 on one side of the first threaded rod 4 to rise. On the other side, the moving block 8 on the reciprocating screw 3 drives the rack 9 to continue to move to the end of the reciprocating screw 3. At this time, both blocking frames 13 on both sides rise, so that the air outlet can deliver cold air, thus completing the simultaneous delivery of cold air.

[0029] When it is necessary to open the air outlet at the inner door of the compartment separately, the servo motor 5 can be started again, causing the reciprocating screw 3 to rotate and drive the moving frame 8 on it to move to the initial position, and drive the rack 9 to move, causing the rack 9 to drive the gear 10 to rotate, causing the second threaded rod 12 to drive the blocking frame 13 to descend, so that the blocking frame 13 blocks the air outlet after descending. Meanwhile, the first threaded rod 4 on one side drives the moving frame 8 on it to continue to move, and the lower blocking frame 13 remains in the position above the air outlet, thereby opening the air outlet at the inner door of the compartment separately, so as to deliver cold air to the fruits and vegetables at the inner door of the compartment and keep the fruits and vegetables at the inner door of the compartment refrigerated.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
