Description

Technical Field

[0001] This invention specifically relates to the field of preservation and disinfection technology, and more specifically to a circulating fruit and vegetable preservation and disinfection machine. Background Technology

[0002] Fresh fruits and vegetables are perishable commodities with high water content. Even after harvesting, they continue to undergo vital processes such as respiration and transpiration. Without proper packaging and transportation, they easily lose water, shrivel, or rot during distribution. Preservation techniques not only reduce product loss but also significantly increase the added value of agricultural products. Packaging and other preservation technologies are crucial means to improve the economic benefits of agricultural products.

[0003] Businesses need to select suitable packaging materials and methods based on research into the characteristics and spoilage mechanisms of fruits and vegetables. First, the packaging should have sufficient mechanical strength to protect the product from damage during loading, unloading, transportation, and stacking. Second, it should have a certain degree of permeability to facilitate the dissipation of heat generated by the product and gas exchange. Third, the packaging container should ideally be moisture-proof to prevent water absorption and deformation. Furthermore, the packaging container must be clean, free of pollution, odor, and toxic chemicals, with a smooth inner wall, an attractive appearance, lightweight, and low cost.

[0004] Because fresh fruits and vegetables are perishable commodities with high water content, they continue to undergo life activities such as respiration and transpiration after harvesting. Therefore, after packaging, they need to be pre-cooled in cold storage to extend their shelf life. Moreover, fruits and vegetables are susceptible to contamination by pathogenic microorganisms after harvesting. For example, citrus fruits are easily contaminated by pathogens such as Penicillium and Green mold, which can cause them to rot and spoil. Therefore, disinfection is necessary before pre-cooling. Some disinfection equipment uses top spraying. However, given the variety of packaging boxes, some boxes have top openings, which can be disinfected using top spraying. Some fruit and vegetable boxes are made of perforated sides to ensure heat dissipation and ventilation, but the effect of disinfecting these boxes using top spraying is slightly less effective. Summary of the Invention

[0005] The purpose of this invention is to provide a circulating fruit and vegetable preservation and disinfection machine that can achieve multi-directional disinfection spraying treatment. This disinfection equipment can work in a cycle to lift, disinfect, and transport fruit and vegetable boxes, achieving integrated disinfection and pre-cooling; thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A circulating fruit and vegetable preservation and disinfection machine includes a disinfection machine and a preservation machine, wherein the disinfection machine is located on one side of the preservation machine; the disinfection machine includes a horizontal frame and a vertical frame welded to one end of the horizontal frame; a drive motor is fixed to the upper end of the side of the vertical frame away from the horizontal frame, and an upper pulley is mounted on the drive shaft of the drive motor; the upper pulley is connected to a lower pulley via a belt; the lower pulley is mounted on the inner side of a mounting plate via a rotating shaft; a clamping block is fixed to the belt by bolts, and a lifting plate is fixed to the inner side of the clamping block by bolts; a support frame is also fixed to one side of the lifting plate.

[0008] A top disinfection spray rack is fixed to the top of the longitudinal frame, a front disinfection spray rack is fixed to the upper end of the side with the transverse frame, and a side disinfection spray rack is fixed to the upper end of the side away from the refrigeration machine; a bottom disinfection component is also provided below the side disinfection spray rack.

[0009] As a further technical solution of the present invention, the lifting plate has two sliding blocks fixed to the side away from the lifting frame by bolts; the sliding blocks are slidably connected to the slide rails; the two slide rails are symmetrically arranged and fixedly connected to the longitudinal frame body; the lifting frame is arranged in an L shape.

[0010] As a further technical solution of the present invention, three roller conveyors are fixed inside the transverse frame; the two lifting frames and the three roller conveyors are arranged alternately.

[0011] As a further technical solution of the present invention, the bottom disinfection component includes a movable frame and a bottom disinfection spray frame; the movable frame is vertically welded to the bottom disinfection spray frame, wherein the movable frame is movably connected to the longitudinal frame body through a rotating shaft.

[0012] As a further technical solution of the present invention, two slide rods and one lead rod are welded to the upper end of the longitudinal frame body, and the lead rod and slide rod are arranged parallel to each other; the two ends of the lead rod are movably connected to the longitudinal frame body through bearings, and a rotary motor is installed at one end; a push plate is also threadedly installed on the lead rod, and the push plate is also slidably connected to the slide rod.

[0013] As a further technical solution of the present invention, the bottom disinfection spray rack, the front disinfection spray rack, the side disinfection spray rack and the top disinfection spray rack all include a rectangular frame, and multiple round tubes are arranged in the rectangular frame. Multiple nozzles are installed on each round tube; the nozzles are all connected to the disinfection machine through flexible hoses.

[0014] As a further technical solution of the present invention, the push plate is arranged in an E-shape; the inner side of the movable frame has two toothed plates, which are staggered with the E-shaped push plate.

[0015] As a further technical solution of the present invention, the preservation machine includes a conveyor, on which a housing is fixedly installed, and an industrial control computer and an air conditioner are installed on the outside of one end of the housing; the conveyor and the air conditioner are electrically connected to the industrial control computer.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In use, the fruits and vegetables in baskets are first placed on the roller conveyor. When the roller conveyor transports the fruit baskets to the longitudinal frame, the drive motor, with the cooperation of the upper and lower pulleys, causes the belt to rotate. The clamping block drives the lifting plate with the support frame to move up along the slide rail, so that the fruit baskets are placed between multiple disinfection spray racks, thereby spraying and disinfecting the fruit baskets. Compared with traditional top spray disinfection equipment, the disinfection effect is better.

[0018] 2. In this invention, after disinfection, the rotary motor drives the lead screw to rotate, and the lead screw converts the rotary motion of the rotary motor into linear motion, causing the pusher plate to slide along the slide bar and push the fruit basket on the lifting frame to the conveyor for pre-cooling treatment. This disinfection mechanism can realize the function of cyclically lifting the fruit basket, and has high working efficiency.

[0019] 3. In this invention, since the movable frame is vertically welded to the bottom disinfection spray frame, when the fruit basket rises, it will push the movable frame to flip upwards. At this time, the bottom disinfection spray frame is located at the bottom of the fruit basket. With the addition of the front disinfection spray frame, the side disinfection spray frame and the top disinfection spray frame, multi-directional disinfection of the fruit basket can be achieved, which greatly improves the disinfection effect of fruits and vegetables.

[0020] 4. In this invention, the inner side of the movable frame has two toothed plates, which are staggered with the E-shaped push plate. This ensures that the push plate can move and transport the fruit basket when the movable frame is upright.

[0021] 5. In this invention, the conveyor transports the fruit baskets to the machine housing, and the cold air generated by the air conditioner is delivered to the machine housing, thereby achieving pre-cooling of the fruits and vegetables and increasing their shelf life.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-7In this embodiment of the invention, a circulating fruit and vegetable preservation and disinfection machine includes a disinfection machine 100 and a preservation machine 200, wherein the disinfection machine 100 is located on one side of the preservation machine 200; the disinfection machine 100 includes a horizontal frame body 101 and a vertical frame body 103 welded to one end of the horizontal frame body 101; a drive motor 1012 is fixed to the upper end of the side of the vertical frame body 103 away from the horizontal frame body 101, and an upper pulley 1013 is fitted on the transmission shaft of the drive motor 1012; the upper pulley 1013 is connected to the lower pulley 1016 via a belt 1014; the lower pulley 1016 is mounted on the inner side of the mounting plate 1017 via a rotating shaft; a clamping block 1015 is fixed to the belt 1014 by bolts, and a lifting plate 1018 is fixed to the inner side of the clamping block 1015 by bolts; a lifting frame 1020 is also fixed to one side of the lifting plate 1018.

[0035] The top of the longitudinal frame 103 is fixed with a top disinfection spray rack 106, the upper end of the side with the transverse frame 101 is fixed with a front disinfection spray rack 104, and the upper end of the side away from the refrigeration machine 200 is fixed with a side disinfection spray rack 105; a bottom disinfection component 107 is also provided below the side disinfection spray rack 105.

[0036] In this embodiment, the lifting plate 1018 has two sliding blocks fixed to the side away from the lifting frame 1020 by bolts; the sliding blocks are slidably connected to the slide rail 1019; the two slide rails 1019 are symmetrically arranged and fixedly connected to the longitudinal frame body 103; the lifting frame 1020 is arranged in an L shape.

[0037] By adopting the above technical solution, when in use, the fruits and vegetables in baskets are first placed on the roller conveyor 102. When the roller conveyor 102 transports the fruit baskets to the longitudinal frame 103, the drive motor 1012, with the cooperation of the upper pulley 1013 and the lower pulley 1016, causes the belt 1014 to rotate. The clamping block 1015 drives the lifting plate 1018, which is equipped with the lifting frame 1020, to move upward along the slide rail 1019, so that the fruit baskets are placed between multiple disinfection spray racks, thereby spraying and disinfecting the fruit baskets. Compared with traditional top spray disinfection equipment, the disinfection effect is better.

[0038] In this embodiment, three roller conveyors 102 are fixed inside the horizontal frame 101; two lifting frames 1020 are arranged at intervals with the three roller conveyors 102.

[0039] By adopting the above technical solution, the lifting frame 1020 and the three roller conveyors 102 are spaced apart, so that the lifting frame 1020 can sink below the roller conveyors 102, making it convenient for the fruit basket to accurately enter the top of the lifting frame 1020.

[0040] In this embodiment, the bottom disinfection component 107 includes a movable frame 107a and a bottom disinfection spray frame 107b; the movable frame 107a and the bottom disinfection spray frame 107b are vertically welded, wherein the movable frame 107a is movably connected to the longitudinal frame body 103 through a rotating shaft.

[0041] More specifically, the push plate 108 is arranged in an E-shape; the inner side of the movable frame 107a has two toothed plates, which are staggered with the E-shaped push plate 108.

[0042] By adopting the above technical solution, it can be ensured that the push plate 108 can move and transport the fruit basket when the movable frame 107a is in the upright state.

[0043] In this embodiment, two slide rods 1011 and a lead screw 109 are welded to the upper end of the longitudinal frame 103, and the lead screw 109 and the slide rods 1011 are arranged parallel to each other; the two ends of the lead screw 109 are movably connected to the longitudinal frame 103 through bearings, and a rotary motor 1010 is installed at one end; a push plate 108 is also threadedly installed on the lead screw 109, and the push plate 108 is also slidably connected to the slide rods 1011.

[0044] By adopting the above technical solution, after disinfection, the rotary motor 1010 drives the lead screw 109 to rotate. The lead screw 109 converts the rotary motion of the rotary motor 1010 into linear motion, so that the push plate 108 slides along the slide bar 1011 and pushes the fruit basket on the lifting frame 1020 onto the conveyor 201 for pre-cooling treatment. This disinfection mechanism can realize the function of cyclically lifting the fruit basket, and has high working efficiency.

[0045] In this embodiment, the bottom disinfection spray rack 107b, the front disinfection spray rack 104, the side disinfection spray rack 105, and the top disinfection spray rack 106 all include a rectangular frame, within which multiple round tubes are arranged, and multiple nozzles are installed on each round tube; all the nozzles are connected to the disinfection machine through flexible hoses.

[0046] By adopting the above technical solution, since the movable frame 107a is vertically welded to the bottom disinfection spray frame 107b, when the fruit basket rises, it will push the movable frame 107a to flip upward. At this time, the bottom disinfection spray frame 107b is located at the bottom of the fruit basket. With the setting of the front disinfection spray frame 104, the side disinfection spray frame 105 and the top disinfection spray frame 106, multi-directional disinfection of the fruit basket can be achieved, which greatly improves the disinfection effect of fruits and vegetables.

[0047] In this embodiment, the preservation machine 200 includes a conveyor 201, on which a housing 202 is fixedly installed. An industrial control computer 203 and an air conditioner 204 are installed on the outside of one end of the housing 202. The conveyor 201 and the air conditioner 204 are electrically connected to the industrial control computer 203.

[0048] By adopting the above technical solution, the conveyor 201 transports the fruit basket to the housing 202, and the cold air generated by the air conditioner 204 is delivered to the housing 202, thereby achieving pre-cooling of the fruits and vegetables and increasing the freshness time of the fruits and vegetables.

[0049] The working principle of this invention is as follows: When in use, the fruits and vegetables in the basket are first placed on the roller conveyor 102. When the roller conveyor 102 transports the fruit basket to the longitudinal frame 103, the drive motor 1012, with the cooperation of the upper pulley 1013 and the lower pulley 1016, causes the belt 1014 to rotate. The clamping block 1015 drives the lifting plate 1018, which is equipped with the lifting frame 1020, to move upward along the slide rail 1019, so that the fruit basket is placed between multiple disinfection spray racks, thereby spraying and disinfecting the fruit basket. Compared with the traditional top spray disinfection equipment, the disinfection effect is better.

[0050] After disinfection, the rotary motor 1010 drives the lead screw 109 to rotate. The lead screw 109 converts the rotary motion of the rotary motor 1010 into linear motion, causing the push plate 108 to slide along the slide bar 1011 and push the fruit basket on the lifting frame 1020 onto the conveyor 201 for pre-cooling. This disinfection mechanism can achieve the function of cyclically lifting the fruit basket, and has high working efficiency.

[0051] Since the movable frame 107a is vertically welded to the bottom disinfection spray frame 107b, when the fruit basket rises, it will push the movable frame 107a to flip upward. At this time, the bottom disinfection spray frame 107b is located at the bottom of the fruit basket. With the setting of the front disinfection spray frame 104, the side disinfection spray frame 105 and the top disinfection spray frame 106, the fruit basket can be disinfected in multiple directions, which greatly improves the disinfection effect of fruits and vegetables.

[0052] The inner side of the movable frame 107a has two toothed plates, which are staggered with the E-shaped push plate 108. This ensures that the push plate 108 can move and transport the fruit basket when the movable frame 107a is upright.

[0053] The conveyor 201 transports the fruit baskets to the housing 202, and the air generated by the air conditioner 204 is delivered to the housing 202, thereby pre-cooling the fruits and vegetables and increasing their shelf life.
