Description

Technical Field

[0001] This utility model relates to the technical field of fruit processing equipment, and in particular to a hydraulic immersion device for large fruit baskets. Background Technology

[0002] Currently, most fruit processing enterprises use iron, wooden, or plastic fruit baskets with dimensions of approximately 1100mm × 1100mm × 800mm for convenient transportation and storage. These baskets have a large capacity, holding 300-350 kg of fruit per basket, and are suitable for mechanized operations during logistics transportation. However, during the fruit washing process, to prevent the fruit from bruising each other, the baskets must be gently submerged in the fruit inlet tank and tilted at a 45-degree angle so that the fruit inside is gently poured into the tank under the action of gravity and water flow before being transported to the next process.

[0003] Currently, there are two main types of immersion operations on the market: one is a combination of manual labor and simple mechanical assistance, which is labor-intensive and requires employees to be in contact with cold water for a long time, especially during the autumn and winter fruit harvest season, when the working environment is harsh; the other is to use imported large-scale mechanical equipment, which has high investment costs and is difficult for rural areas or small-scale enterprises to afford.

[0004] Therefore, there is a need for a fruit basket immersion device that can reduce labor intensity, avoid personnel contact with cold water, and is cost-effective and suitable for small and medium-sized enterprises. Utility Model Content

[0005] (1) Technical solution To solve the above-mentioned technical problems, this utility model provides a hydraulic immersion device for large fruit baskets, including a water tank, a hanging basket, a main shaft, guide rails, pulleys, a hydraulic cylinder, a rotating pressure plate, a pressure rod, a counterweight assembly, fixed pulleys, ropes, and chains. A frame spans above the water tank, and square guide rail plates are installed on both sides of the frame. Inclined guide rails are provided on the guide rail plates, and each guide rail contains a slidably connected pulley. A main shaft spans above the water tank, and two pulleys are fixed to both ends of the main shaft. The tops of both sides of the hanging basket are rotatably mounted on the main shaft via bearing seats. The frame is equipped with hydraulic cylinders that drive the pulleys on the main shaft to slide along the guide rail. A rotating pressure plate is rotatably mounted on the main shaft between the bearing seat and the adjacent pulley. A pressure rod is connected between one end of the two rotating pressure plates. A pair of fixed rods are arranged parallel to each other on the inner wall of the top of the frame. A fixed pulley is installed at the bottom of one end of the fixed rod. A rope is wound around the fixed pulley and one end is connected to the other end of the rotating pressure plate. The other end of the rope is connected to the counterweight assembly. A chain is connected between the other end of the fixed rod and the bottom corner of the basket directly below it.

[0006] Preferably, the frame is inverted U-shaped and the two vertical arms are fixed to both sides of the water tank.

[0007] Preferably, the cylinder body of the hydraulic cylinder is hinged to the frame, and the piston rod of the hydraulic cylinder is arranged upward and its upper end is hinged to the end of the main shaft.

[0008] Preferably, a bearing is provided at the connection between the rotating pressure plate and the main shaft.

[0009] Preferably, the counterweight assembly includes a counterweight block, a counterweight limiting block, and a connecting rod. A pair of the counterweight limiting blocks are respectively provided on both sides of the frame. The counterweight block is vertically slidably connected between the pair of counterweight limiting blocks on each side, and the connecting rod is connected between the two counterweight blocks.

[0010] Preferably, the other end of the rope is fixedly connected to the connecting rod.

[0011] (2) Beneficial effects This utility model provides a hydraulic immersion device for large fruit baskets. Compared with the prior art, this utility model has the following advantages: 1. By installing inclined guide rails on both sides of the water tank, the travel and inclination angle of the guide rails are determined according to the running trajectory of the basket. Driven by a hydraulic cylinder, the pulley drives the main shaft to move along the guide rail, enabling the basket to move along a predetermined inclined trajectory. This trajectory design allows the basket to make a large displacement from the inlet position (near the forklift) towards the outlet direction, which can avoid the water flow generator in the water tank and provide space for the subsequent turning of the fruit basket.

[0012] 2. When the basket carrying the fruit basket reaches the starting point of the water entry, the rotating pressure plate, under the action of the counterweight, presses down on the fruit basket through the pressure rod, restricting its displacement, effectively overcoming the drift caused by buoyancy after the fruit basket enters the water, and ensuring the immersion process is stable.

[0013] 3. A chain installed between the bottom corner of the basket and the fixed rod is in a slack state before the basket moves to the tipping point, exerting no constraint on the basket. Upon reaching the tipping point, the chain is tensioned, restricting the basket's downward movement on the fruit-feeding side. At this time, the piston rod of the hydraulic cylinder continues to retract, pulling the main shaft diagonally downward along the guide rail. Due to the chain's constraint on the bottom corner of the basket, the basket cannot synchronously follow the main shaft downwards, forcing the basket to tip towards the water outlet side around the main shaft until it reaches a 45-degree angle, allowing the fruit to gently pour out under the combined force of gravity and water pressure.

[0014] 4. After unloading is completed, the piston rod of the hydraulic cylinder extends, pushing the main shaft to move obliquely upward along the guide rail. Under the guidance of the chain and the action of gravity, the basket gradually returns to the correct position and rises, eventually returning to the initial position, making it easy for the forklift to take away the empty basket and put in the full basket, realizing the cycle operation.

Detailed Implementation

[0022] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1-6As shown, the hydraulic immersion device for large fruit baskets of this utility model includes a water tank 1, a hanging basket 2, a main shaft 3, guide rails 6, pulleys 7, a hydraulic cylinder 8, a rotating pressure plate 9, a pressure rod 11, a counterweight assembly, fixed pulleys 16, ropes 17, and chains 18. A frame spans above the water tank 1, and square guide rail plates 5 are installed on the frame on both sides of the water tank 1. The guide rail plates 5 are provided with inclined guide rails 6, and the stroke and inclination angle of the guide rails 6 are designed according to the running trajectory of the hanging basket 2. Each guide rail 6 is slidably connected to a pulley 7. The main shaft 3 spans above the water tank 1, and two pulleys 7 are fixed to the two ends of the main shaft 3. The hanging basket 2 is a basket body used to support the large fruit basket, and its top sides are rotatably mounted on the main shaft 3 through bearing seats 4, so that the hanging basket 2 can be flipped relative to the main shaft 3. Hydraulic cylinders 8, capable of driving pulleys 7 on the main shaft 3 to slide along the guide rail 6, are respectively installed on the frames on both sides of the water tank 1. A rotating pressure plate 9 is rotatably installed on the main shaft 3 between the bearing seat 4 and the adjacent pulley 7. A pressure rod 11 is connected between one end of the two rotating pressure plates 9. A pair of fixed rods 15 are arranged parallel to each other on the inner wall of the top of the frame. A fixed pulley 16 is installed at the bottom of one end of the fixed rod 15. A rope 17 is wound around the fixed pulley 16 and one end is connected to the other end of the rotating pressure plate 9. The other end of the rope 17 is connected to the counterweight assembly. A chain 18 is connected between the other end of the fixed rod 15 and the bottom corner of the basket 2 directly below it. The length of the chain 18 is calculated to ensure that it is in a slack state before the basket 2 moves to the flipping starting point and is straightened and constrained after the flipping starting point.

[0024] The frame is inverted U-shaped, with two vertical arms fixed to the ground on both sides of the water tank 1. The cylinder body of the hydraulic cylinder 8 is hinged to the frame, and the piston rod 81 of the hydraulic cylinder 8 is set upward and its upper end is hinged to the end of the main shaft 3. Through the synchronous extension and retraction of the two hydraulic cylinders 8, the pulleys 7 at both ends of the main shaft 3 can be driven to slide along the guide rail 6, thereby driving the basket 2 to move along a preset oblique trajectory.

[0025] A bearing 10 is provided at the connection between the rotating pressure plate 9 and the main shaft 3. The counterweight assembly includes a counterweight block 12, a counterweight limiting block 14 and a connecting rod 13. A pair of counterweight limiting blocks 14 are provided on each side of the frame. The counterweight block 12 is vertically slidably connected between the pair of counterweight limiting blocks 14 on each side. The connecting rod 13 is connected between the two counterweight blocks 12. The other end of the rope 17 is fixedly connected to the connecting rod 13.

[0026] Workflow: (1) Initial loading: The piston rod 81 of the hydraulic cylinder 8 is fully extended, and the drive spindle 3 and the basket 2 are located at the top and highest position of the guide rail 6, i.e., the initial position. At this time, the pressure rod 11 is in a raised state under the action of the counterweight 12, maintaining a certain distance from the basket 2. The forklift smoothly places the large fruit basket full of fruit into the basket 2, completing the loading.

[0027] (2) Translational descent and pressing: The piston rod 81 of the hydraulic cylinder 8 retracts, pulling the main shaft 3, causing the pulley 7 to slide along the guide rail 6. The basket 2 carries the fruit basket down obliquely and moves horizontally to the other side of the water tank 1 (fruit discharge direction). When the basket 2 moves to the point where the fruit basket is about to touch the water surface, the rotating pressure plate 9 is released from the limit position. Under the action of the counterweight 12, the rotating pressure plate 9 is pulled to rotate by the rope 17, causing the pressure rod 11 to press down and stick tightly to the top of the fruit basket to prevent it from drifting after entering the water.

[0028] (3) Immersion and Tilting: The basket 2 continues to descend, and the fruit basket is completely immersed in the water. When the basket 2 moves to the set turning point, the chain 18 is straightened, restricting the fruit-infeeding side (the side closer to the initial position) of the basket 2 from continuing to move. The piston rod 81 of the hydraulic cylinder 8 continues to retract, pulling the main shaft 3 along the guide rail 6 diagonally downward (towards the water tank). Due to the constraint of the chain 18, the basket 2 rotates around the main shaft 3 toward the water outlet side until it rotates 45 degrees. At this time, the fruit is gently poured out of the basket under the action of gravity and water flow and enters the water tank 1.

[0029] (4) Reset: After unloading, the piston rod 81 of the hydraulic cylinder 8 extends, pushing the main shaft 3 to move obliquely upward (away from the water tank) along the guide rail 6. Under the guidance of the chain 18 and gravity, the basket 2 gradually returns to the correct position and rises, eventually returning to the initial high position. The pressure rod 11 is lifted again during the movement. The forklift can take away the empty fruit basket and put in the next full basket, and the operation is repeated.

However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
