Description

Technical Field

[0001] This utility model relates to the technical field of fruit harvesting boxes, specifically a harvesting box for planting yellow crystal fruit. Background Technology

[0002] As a tropical fruit, the yellow jujube is prone to oxidative browning after harvesting, which affects the quality and storage time of the fruit.

[0003] Currently, there is a lack of integrated processing equipment specifically designed for the characteristics of yellow jujube during the planting and harvesting process. After harvesting, the yellow jujube often needs to be manually transported to a specific location for anti-oxidation treatment, which is cumbersome, inefficient, and the fruit is easily damaged due to collisions during transportation.

[0004] Meanwhile, the existing collection equipment has limited functionality and cannot meet the needs of immediate anti-oxidation treatment and wrapping with plastic wrap after the harvest of yellow crystal fruit, which is not conducive to the preservation and subsequent storage and transportation of yellow crystal fruit.

[0005] Therefore, in order to address the above problems, there is an urgent need for a planting and harvesting box that can achieve immediate anti-oxidation treatment of yellow crystal fruit after harvesting and is easy to operate. Utility Model Content

[0006] (a) Technical issues This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, the purpose of this utility model is to propose a yellow crystal fruit planting and harvesting box, which addresses the problems of lack of post-harvest processing equipment, cumbersome operation, and low efficiency in the existing technology.

[0008] (II) Technical Content To achieve the above objectives, this utility model proposes a yellow crystal fruit planting and harvesting box including a frame and an anti-oxidation treatment mechanism, wherein: A storage box is formed on the frame, and a top frame is provided on the front side of the frame; The anti-oxidation treatment mechanism is installed on the top frame, and its height is designed to facilitate the standing operation of the harvesters. The anti-oxidation treatment mechanism includes a liquid pool mounted on a top frame and an immersion net box placed in the liquid pool.

[0009] The liquid tank contains a 0.5% citric acid solution. After harvesting, the yellow berries are placed in a soaking net box and then immersed in the liquid tank for 1 minute to delay oxidative browning. After soaking, the soaking net box is removed, excess liquid is drained, and then the berries are wrapped in plastic wrap. They do not need to be completely dried; a very thin layer of liquid film is sufficient.

[0010] In addition, the yellow crystal fruit planting and harvesting box proposed above according to this utility model may also have the following additional technical features: Preferred technical solution 1: Protruding plates extend from the left and right sides of the front end of the top frame, and slots are provided on the upper side of the protruding plates, with a long rod placed between the two sets of slots; The long rod passes through the core of the plastic wrap roll.

[0011] Preferred technical solution 2: The liquid pool is placed in the frame structure of the top frame.

[0012] Preferred technical solution 3: Vertical rails are fixed on both the left and right sides of the top frame; The protruding handles extending from the left and right sides of the soaking net box respectively extend into two sets of vertical tracks, and the soaking net box is immersed in or removed from the liquid pool by moving along the vertical tracks.

[0013] Preferred technical solution four: A movable handle is rotatably connected to the convex handle, and two sets of notches are formed on the front wall of the vertical track, referred to as the lower notch and the upper notch, respectively; When the soaking net cage is fully immersed in the liquid pool, the movable handle is moved to the position facing the notch. At this time, the movable handle is rotated to make it lock into the lower notch. After soaking, lift the soaking net box up until the movable handle moves to the height of the upper notch, and rotate the movable handle to make it lock into the upper notch.

[0014] Preferred technical solution five: A buffer spring is provided between the convex handle and the bottom wall of the vertical track.

[0015] Preferred technical solution six: The top of the vertical track is open.

[0016] (III) Technical Effects The above structure gives this solution the following advantages: 1. This utility model is equipped with an anti-oxidation treatment mechanism, which allows harvesters to immediately soak the yellow crystal fruit in a 0.5% citric acid solution after harvesting, effectively delaying oxidative browning, ensuring fruit quality, and the treatment process can be completed on the collection box without additional handling, thus improving work efficiency. 2. The slot and long rod design on the front convex plate of the top rack makes it easy to place the plastic wrap roll, so that the yellow crystal fruit can be wrapped with plastic wrap in time after draining, which further improves the preservation effect and is easy to operate. 3. The top frame has a frame structure, in which the liquid tank is inserted, which facilitates the installation and disassembly of the liquid tank and makes it easy to clean and replace the citric acid solution; 4. The soaking net box moves in the vertical track by means of the convex handle to realize the operation of immersion and lifting in the liquid pool. With the cooperation of the movable handle and the upper and lower notches, the soaking and draining height can be stably limited to ensure the stability of the treatment effect. 5. The buffer spring between the convex handle and the bottom wall of the vertical track can prevent hard collisions when the soaking net cage is lowered, protecting the equipment and the yellow crystal fruit from damage; 6. The vertical track has an open top, which makes it easy to remove the soaking net cage, facilitates cleaning and maintenance of the net cage, and also makes it easy to replace the net cage when processing different batches of yellow crystal fruit.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The following description, in conjunction with the accompanying drawings, describes the *Gynostemma pentaphyllum* planting and harvesting box of this utility model.

[0021] Please see Figures 1-3The *Gynostemma pentaphyllum* planting and harvesting box of this utility model embodiment includes a frame 1 and an anti-oxidation treatment mechanism 2, specifically: The bottom of the frame 1 is equipped with four casters 11 with brakes, facilitating the movement and securing of the equipment within the orchard. The storage box 12 on the frame 1 can hold stacked packaging boxes for yellow jujubes. A top frame 14 is welded to the top of the vertical frame 13 on the front side of the frame 1. The top frame 14 has a rectangular frame structure, and the anti-oxidation treatment mechanism 2 is installed on the top frame 14. Its height is suitable for pickers of 1.5-1.8m in height to stand and operate. The anti-oxidation treatment mechanism 2 includes a liquid tank 21 and an immersion net box 22. The liquid tank 21 is made of food-grade polypropylene. The top edge of the liquid tank 21 is bent outward to form a convex edge 211. When the lower part of the liquid tank 21 is placed in the frame structure, the convex edge 211 is locked onto the upper edge of the frame structure of the top frame 14 to fix the liquid tank 21. The liquid tank 21 is filled with 0.5% citric acid solution.

[0022] Vertical rails 3 are fixed on both the left and right sides of the top frame 14. The vertical rails 3 are made of stainless steel plates bent into a "U" shaped groove structure. The bottom is sealed by a base plate to form a bottom wall, and the top of the vertical rails 3 is open.

[0023] The soaking net box 22 is woven from stainless steel wire. The size of the soaking net box 22 is adapted to the liquid pool 21. The top left and right sides of the soaking net box 22 have protruding handles 221 extending outward. The protruding handles 221 extend into two sets of vertical rails 3 respectively. The protruding handles 221 are fitted with the inner wall of the vertical rails 3 with a clearance. By moving along the vertical rails 3, the soaking net box 22 can be immersed in the liquid pool 21 or lifted out of the liquid pool 21.

[0024] In one embodiment Please see Figures 1-5 To ensure the stability of the net cage 22 during drainage or soaking, a movable handle 223 is rotatably connected to the end of the protruding handle 221 away from the net cage. The movable handle 223 is dampedly connected to the protruding handle 221 and can rotate around the protruding handle 221. Two sets of notches are formed on the front wall of the vertical track 3. The notches are rectangular, with the lower notch 32 near the bottom of the vertical track 3 and the upper notch 31 near the top of the vertical track 3.

[0025] When the soaking net box 22 is fully immersed in the liquid pool 21, the movable handle 223 is moved to the position directly opposite the lower notch 32. At this time, the movable handle 223 is rotated to lock into the lower notch 32, thus limiting the soaking height of the soaking net box 22 and ensuring that the yellow quartz fruit is completely submerged in the solution for a processing time of 1 minute (time controlled by the operator). After soaking, the movable handle 223 is first rotated back to disengage it from the lower notch 32, and then the soaking net box 22 is raised until the movable handle 223 moves to the height of the upper notch 31. The movable handle 223 is then rotated to lock into the upper notch 31, limiting the draining height of the soaking net box 22. At this time, the bottom of the soaking net box 22 is detached from the liquid surface of the liquid pool 21, allowing the excess liquid on the surface of the yellow quartz fruit to drain within 30-60 seconds, leaving a very thin liquid film.

[0026] In one embodiment Please see Figures 3-4 To prevent the soaking net cage 22 from colliding hard with the vertical track 3 or the bottom wall of the liquid pool 21 when it is lowered, a buffer spring 4 is installed between the convex handle 221 and the bottom wall of the vertical track 3. A vertical rod 33 is erected in the vertical track 3. A sleeve fixed through the protruding handle 221 is slidably sleeved on the vertical rod 33. The end of the movable handle 223 is connected to the sleeve shaft 222 in a damped rotational manner. The buffer spring 4 is placed on the vertical rod 33, with its upper end abutting against the protruding handle 221 and its lower end fixedly connected to the bottom wall of the vertical track 3.

[0027] In one embodiment Please see Figure 1 , Figure 2 , Figure 4 Rectangular protrusions 15 extend from the left and right sides of the front end of the top frame 14. The upper side of the protrusion 15 is provided with a slot 151. The slot 151 is an oblique slot. Two sets of slots 151 are symmetrically arranged. A set of long rods 5 are placed in the two sets of slots 151. The long rods 5 are stainless steel round rods. The long rods 5 are used to pass through the core of the plastic wrap roll, which facilitates the placement and use of the plastic wrap.

[0028] During use, harvesters place the yellow jujubes into the soaking net box 22, filling it to no more than 2 / 3 full at a time to avoid squeezing the fruits. Then, holding the top edge of the soaking net box 22, they move it down the vertical track 3 via the handle 221. During this movement, the buffer spring 4 gradually compresses, providing cushioning. When the movable handle 223 is positioned directly opposite the lower notch 32, it is rotated to engage with the lower notch 32, allowing the yellow jujubes to soak in the liquid pool 21 for 1 minute. Afterward, the movable handle 223 is rotated in the opposite direction to disengage it from the lower notch 32. Holding the edge of the soaking net box 22, the harvesters lift it until the movable handle 223 reaches the height of the upper notch 31. The handle is then rotated to engage with the upper notch 31 for draining. After draining, the cling film is removed, and each yellow jujube is wrapped individually, ensuring the film adheres tightly to the fruit surface to minimize air residue. Finally, the fruit is placed in a packaging box on the tray. When the citric acid solution in the liquid tank 21 has been used for 4 hours or when 50 kg of yellow quartz fruit has been processed, remove the liquid tank 21 from the top frame 14, pour out the old solution, rinse it with clean water, and then refill it with a new 0.5% citric acid solution. When it is necessary to clean the soaking net box 22, lift the soaking net box 22 so that the protruding handle 221 is completely detached from the top opening of the vertical track 3, rinse the soaking net box 22 with clean water, and then reinstall it.

[0029] During use, this solution requires daily maintenance of each component according to the established maintenance plan to ensure its working condition.
