Description

Technical Field

[0001] This utility model relates to the field of durian processing equipment, and in particular to a durian cleaning device. Background Technology

[0002] After harvesting, durians accumulate a lot of dust on their surface during growth. To ensure a better appearance for sale, the durians need to be cleaned. Normally, workers simply rinse them with water hoses. However, because there are gaps between the thorns on the durian's surface, cleaning with water hoses is ineffective. Using brushes is also inefficient, as the numerous thorns are sharp and difficult to handle manually.

[0003] The patent application number "202011225799.6" entitled "A Durian Cleaning Device" has a structure that can only rinse a single durian, cannot perform batch operations, and has a single rinsing direction, which cannot guarantee complete rinsing. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a durian cleaning device that can rinse durians in batches and clean them more thoroughly.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A durian cleaning device includes a conveying mechanism, a rinsing mechanism, and a drying mechanism; The conveying mechanism includes a base on which a chain conveying mechanism is mounted. The chain conveying mechanisms are arranged side by side, and multiple connecting rods are arranged at intervals along the length of the chain between the two chain conveying mechanisms. The sprockets of the two chain conveying mechanisms are arranged coaxially and driven by a first motor. The flushing mechanism is located in front of the conveying mechanism. The flushing mechanism includes left and right main pipes. The input end of the main pipe is connected to the pump body. The lower end of the two main pipes is connected to a lower flushing pipe along the length direction. The upper end of each main pipe is connected to a vertical pipe along the length direction. The upper end of the left and right vertical pipes is connected to an upper flushing pipe. Nozzles are installed on the lower flushing pipe, the vertical pipe, and the upper flushing pipe. All nozzles face the side of the conveying mechanism. The drying mechanism is located at the rear of the conveying mechanism. The drying mechanism includes an up-and-down adjustment mechanism, on which a centrifugal fan is installed. The centrifugal fan is connected to an air knife, which faces the conveying mechanism.

[0006] The conveying mechanism consists of two sets arranged side by side; the sprockets at the input ends of the two conveying mechanisms are coaxial, and the sprockets at the output ends of the two conveying mechanisms are coaxial.

[0007] The upper flushing pipe has a vertically arranged transition pipe facing downwards in the middle, and nozzles are arranged on both sides of the transition pipe.

[0008] The nozzles are arranged alternately in the vertical direction on the upper and lower flushing pipes; the nozzles are also arranged alternately in the horizontal direction on the left and right vertical pipes and transition pipes.

[0009] A protective cover is fixed on the base, and a rain curtain is fixed at the front and rear ends of the protective cover.

[0010] The up-down adjustment mechanism includes left and right vertical slide grooves, and the mounting plate is arranged horizontally and slides in cooperation with the left and right vertical slide grooves; a screw is rotatably mounted on the mounting plate in both the left and right directions, the screw is threadedly connected to a nut, and the nut is fixed at the upper end of the vertical slide groove.

[0011] A centrifugal fan is also installed at the lower end of the rear section of the conveying mechanism.

[0012] This utility model provides a durian cleaning device, which has the following technical effects: 1) By setting up a conveyor mechanism, which is about 20 meters long, multiple durians can be continuously conveyed. There are two sets of conveyor mechanisms, arranged side by side, which improves the conveying efficiency and only requires one motor to drive them.

[0013] 2) By setting a rinsing mechanism at the front of the conveying mechanism and a drying mechanism at the rear of the conveying mechanism, rinsing and drying can be carried out in one operation; at the same time, since the nozzles are arranged up, down and left and right, and the centrifugal fan is arranged up and down, rinsing is efficient and drying is fast.

[0020] like Figure 1-2 As shown, a durian cleaning device includes a conveying mechanism 1, a rinsing mechanism 2, and a drying mechanism 3. The conveying mechanism 1 is used to convey durians 6, the rinsing mechanism 2 is used to clean durians 6, and the drying mechanism 3 is used to roughly dry the water on the durians 6.

[0021] Figure 1-2 In the diagram, the chain portion of the conveying mechanism 1 is drawn, and the nozzle portion of the rinsing mechanism 2 is drawn.

[0022] like Figure 2-3 As shown, the conveying mechanism 1 includes a base 1.1, within which chain conveying mechanisms 1.2 are arranged symmetrically side-by-side along the length direction. Multiple connecting rods 1.3 are spaced apart along the length direction on the chain between the two chain conveying mechanisms 1.2. The length of each connecting rod 1.3 is greater than the length of the durian 6. The spacing between adjacent connecting rods 1.3 is less than the width of the durian 6, facilitating support for the durian and allowing it to move forward with the connecting rods 1.3. The sprockets of the two chain conveying mechanisms 1.2 are coaxially arranged and driven by a first motor 1.4.

[0023] The conveying mechanism 1 is arranged in two groups, left and right, side by side, and the sprockets of the two conveying mechanisms 1 are arranged coaxially. That is, the two groups of conveying mechanisms 1 are driven by the same motor 1.4, which saves energy.

[0024] like Figure 2 , Figure 4 As shown, the rinsing mechanism 2 is distributed along the length of the conveying mechanism 1 and is arranged in multiple groups. Each group of rinsing mechanisms 2 includes left and right main pipes 2.1, which are located below the conveying mechanism 1 and parallel to the chain. The input end of the main pipe 2.1 is connected to the pump body 2.7, and the other end of the pump body 2.7 is connected to the water tank through a pipe. The lower ends of the two main pipes 2.1 are connected with lower rinsing pipes 2.2 along the length direction at intervals, and the upper ends of the two main pipes 2.1 are connected with vertical pipes 2.3 along the length direction at vertical length. The upper ends of the left and right vertical pipes 2.3 are connected with upper rinsing pipes 2.4. Nozzles 2.5 are installed on the lower rinsing pipes 2.2, vertical pipes 2.3, and upper rinsing pipes 2.4, and the nozzles 2.5 face the conveying mechanism 1.

[0025] Preferably, when there are two sets of conveying mechanisms 1, a transition pipe 2.6 is arranged in the middle of the upper flushing pipe 2.4. The transition pipe 2.6 is arranged vertically, and nozzles 2.5 are arranged on both the left and right sides of the transition pipe 2.6.

[0026] The durian is thoroughly rinsed using nozzles 2.5 on the top, bottom, left, and right sides to ensure it is clean.

[0027] Preferably, the nozzles 2.5 are staggered horizontally on the upper flushing pipe 2.4 and the lower flushing pipe 2.2; the nozzles 2.5 are also staggered vertically on the left and right vertical pipes 2.3 and the transition pipe 2.6, so as to ensure that multiple positions of the durian in all directions can be rinsed.

[0028] The tube body of the rinsing mechanism 2 is located above the front section of the conveying mechanism 1. A protective cover 4 is fixed on the base 1.1 outside the rinsing mechanism 2. Rain curtains 5, made of rubber, are fixed to the upper ends of the front and rear ends of the protective cover 4. The rain curtains 5 and the protective cover 4 can prevent water from splashing.

[0029] The drying mechanism 3 is located above the rear section of the conveying mechanism 1, and there are multiple drying mechanisms 3 arranged along the length of the conveying mechanism 1.

[0030] like Figure 5 As shown, each drying mechanism 3 includes left and right vertical slides 3.1. A hole is opened on the horizontal plate at the upper end of the vertical slide 3.1, and a nut 3.2 is welded to the opening. A screw 3.3 is threadedly connected to the nut 3.2, and its lower end extends out of the opening and is rotatably connected to the mounting plate 3.4. The mounting plate 3.4 is horizontally arranged and slides with the vertical slides 3.1. By rotating the screw 3.3, the screw 3.3 moves up and down relative to the nut 3.2, thereby adjusting the height of the mounting plate 3.4.

[0031] Two centrifugal fans 3.5 are installed on the upper end of the mounting plate 3.4. The lower end of the centrifugal fans 3.5 extends out of the opening of the mounting plate 3.4 and connects to the air knife 3.6. The air outlet at the lower end of the air knife 3.6 faces the conveying mechanism 1.

[0032] By adjusting the height of the mounting plate 3.4, the distance between the air outlet of the air knife 3.6 and the surface of the durian can be adjusted, thereby adjusting the blowing effect.

[0033] In addition, a centrifugal fan 3.5 is also installed below the rear end of the conveying mechanism 1, with the air outlet of the air knife 3.6 of the centrifugal fan 3.5 facing upwards. By blowing air up and down, the drying efficiency can be improved.

[0034] In addition, a water collection tank is provided at the lower end of the conveying mechanism 1. The water collection tank pumps water into the sedimentation tank for sedimentation and reuse through the return water pipe, pump body and other means.

[0035] Working principle and process: 1) The durians 6 are placed on the input end of the conveying mechanism 1 by hand in sequence, and multiple durians 6 are conveyed forward at intervals.

[0036] 2) When the durian 6 passes through the rinsing mechanism 2, it is sprayed and washed by the nozzles 2.5 in the upper, lower and left and right directions.

[0037] 3) Then it enters the drying mechanism 3, where the water is blown away by the up and down airflow.

[0038] 4) When it reaches the output end of the conveying mechanism 1, it can be removed manually or enter the next section of the conveying mechanism 1 to carry out the next process.
