[0039] Figure 1 An alternative embodiment of a fruit and vegetable basket loading system is shown.

[0040] In this optional embodiment, the fruit and vegetable basket system includes: a drainage device 100, a basket device 200 and a first drive device 400. The drainage device 100 includes a water tank 101, in which liquid is stored. The drainage device 100 uses the water flow formed by the liquid to divert the fruits and vegetables, and the buoyancy of the liquid can buffer the fruits and vegetables to prevent collisions between the fruits and vegetables. The basket device 200 is installed on the frame 300, and the first drive device 400 drives the basket device 200 to move in the vertical direction to control the depth of the basket device 200 immersed in the water tank 101. Figure 1 In the illustrated embodiment, the basket loading device 200 is installed on the top of the frame 300 through a longitudinal beam. The first drive device 400 is powered by a motor, and drives the longitudinal beam and the basket loading device 200 to rise and fall through a gear and rack structure. Of course, the first drive device 400 can use an electric cylinder, a pneumatic cylinder, etc. to provide power to realize the lifting and lowering operation of the basket loading device.

[0041] The various embodiments of the present invention are described using water as an example. Of course, water is only illustrative, and other liquids may also be used in the water tank.

[0042] Figure 2a and Figure 2b An alternative embodiment of a drainage device is shown.

[0043] like Figure 2a and Figure 2b As shown, the drainage device 100 includes a water tank 101, and a water inlet 102 and a water outlet 103 are provided on the water tank. Water is passed through the water inlet 102, and the water is discharged from the water outlet 103 to form a water flow flowing from the water inlet side to the water outlet side, and the water flow is used as the power for the transmission of fruits and vegetables in the entire system. The drainage device also includes a first barrier screen 104, and the first barrier screen 104 is used to open or close the channel for fruits and vegetables to enter the basket device 200. The fruits and vegetables to be basketed are gathered on the first barrier screen 104 under the drive of the water flow. When the first barrier screen 104 is opened, the fruits and vegetables enter the basket device 200. When the first barrier screen 104 is closed, the fruits and vegetables entering the basket device 200 are basketed, and the fruits and vegetables blocked by the first barrier screen 104 outside the basket device 200 wait for the next cycle. Optionally, the width of the first barrier screen 104 is set according to the size of the fruit and vegetable basket. Optionally, the width of the first barrier screen 104 is less than or equal to the width of the vegetable and fruit basket.

[0044] The front and rear directions in the embodiment of the present invention are based on the direction of water flow in the water tank, and the water flows from front to rear.

[0045] The water tank 101 stores water, which acts as a buffer for the fruits and vegetables. Therefore, the fruits and vegetables can be directly introduced into the water tank 101. Figure 2a As shown, the drainage device further includes a vegetable and fruit introduction port 107 , through which vegetables and fruits are introduced into the water tank.

[0046] Alternatively, if Figure 2b As shown, the drainage device further includes a drainage plate 108 . The drainage plate 108 is disposed in front of the first barrier screen 104 and is used to drain the fruits and vegetables to the first barrier screen 104 .

[0047] Optionally, the first barrier screen 104 is a hollow structure or a grid structure or a mesh structure, so as to achieve the effect of blocking fruits and vegetables without blocking water flow. Figure 2a As shown, the first barrier screen 104 is a row of L-shaped columns, and the distance between the columns is less than the diameter of the fruits and vegetables to achieve the purpose of blocking the fruits and vegetables. Optionally, the first barrier screen is a mesh structure. Optionally, the drainage device 100 also includes a second driving device 105, which drives the first barrier screen to move in the vertical direction to open or close the passage for the fruits and vegetables to enter the basket device. Figure 2a In the illustrated embodiment, the second driving device 105 is a motor, which drives the first barrier screen 104 to move in the vertical direction through a transmission belt. Of course, the second driving device 105 can use a power device such as an electric cylinder or a pneumatic cylinder to realize the lifting and lowering operation of the first barrier screen. The second driving device 105 drives the first barrier screen 104 to lift and lower, which can provide universality of the entire system. For example, different fruit and vegetable basketing processes require different water levels, and different fruits and vegetables have different draft depths. The first barrier screen 104 is adjusted in height according to different fruits and vegetables.

[0048] Optionally, the fruit and vegetable basketing system further includes a first detection device, which is used to detect the number of fruits and vegetables in the collection section and output a control signal to control the first barrier screen to open or close. When the number of fruits and vegetables in the collection section 220 reaches a preset number, the first detection device outputs a control signal to control the first barrier screen to close, and subsequent fruits and vegetables are blocked in front of the first barrier screen, and the basketing device 200 baskets the collected fruits and vegetables. Optionally, the first detection device includes a visual detection module, which outputs a control signal based on the image of fruits and vegetables. Optionally, the visual detection module is arranged at the top of the collection section, collects images in the collection section, and outputs a control signal based on the image of fruits and vegetables. For example, when the image collected by the visual detection module shows that the fruits and vegetables in the collection section are full, the first detection device outputs a control signal to control the first barrier screen to close, and the basketing device baskets the fruits and vegetables in the collection section. Optionally, the visual detection module is arranged in front of the first barrier screen. For example, when the image collected by the visual detection module shows that the fruits and vegetables in front of the first barrier screen are gathered and not moving, and the fruits and vegetables in the collection part are full, the first detection device outputs a control signal to control the first barrier screen to close, and the basket loading device performs a basket loading operation on the fruits and vegetables in the collection part. Figure 2a As shown, the first detection device is arranged in front of the first barrier screen, including a baffle 106 and a position sensor (not shown), the baffle 106 is arranged at the floating height of the fruits and vegetables, the position sensor detects the position of the baffle, and the first detection device outputs a control signal according to the position of the baffle. For example, when the fruits and vegetables in the collection part are full, the fruits and vegetables in front of the first barrier screen gather and do not move, and the baffle position remains inclined or horizontal, then the first detection device outputs a control signal according to the position of the baffle, controls the first barrier screen to close, and the basket loading device performs basket loading operation on the fruits and vegetables in the collection part. When the fruits and vegetables in the collection part are not full, the fruits and vegetables in front of the first barrier screen drift toward the collection part all the time, and the baffle 106 is always in a swinging state, then the first detection device does not output a control signal, or outputs a control signal to control the first barrier screen to remain open. Optionally, the position sensor is a travel switch arranged on the swinging track of the baffle, and the baffle position is detected by the travel switch. Optionally, the position sensor is an angle sensor, and the angle sensor detects the rotation angle of the baffle.

[0049] Figure 3a An alternative embodiment of a basket loading device is shown.

[0050] like Figure 3aAs shown, the basket loading device 200 includes a clamping portion 210 and a collecting portion 220; the clamping portion 210 is used to clamp the vegetable and fruit basket 230; the collecting portion 220 has a vegetable and fruit accommodating space and is provided with a drainage structure, and the collecting portion 220 is arranged above the clamping portion 210. After the clamping portion 210 clamps the vegetable and fruit basket 230, the collecting portion 220 is located above the vegetable and fruit basket 230, and the bottom of the collecting portion 220 is opposite to the basket opening of the vegetable and fruit basket 230. A second blocking screen 222 is arranged at the bottom of the collecting portion, and the second blocking screen 222 is used to open or close the bottom of the collecting portion. When the second blocking screen 222 is opened, the collecting portion is connected to the vegetable and fruit basket below, and the vegetables and fruits can enter the vegetable and fruit basket from the collecting portion. When the second blocking screen 222 is closed, the collecting portion is separated from the vegetable and fruit basket.

[0051] The first barrier screen 104 is opened, and when the vegetables and fruits in the collection part 220 reach a preset number, the first barrier screen 104 is closed. The first driving device 400 drives the basket loading device 200 to lift as a whole, and the second barrier screen 222 is opened, and the vegetables and fruits float on the water surface. Therefore, during the lifting process of the basket loading device, the vegetables and fruits in the collection part enter the vegetable and fruit basket below, and are stacked with the vegetables and fruits in the lower layer under the buoyancy of the water, so as to realize the transfer of vegetables and fruits from the collection part to the vegetable and fruit basket. The buoyancy of the water plays a good buffering role in the stacking process of the upper and lower vegetables and fruits, thereby avoiding damage to the vegetables and fruits. When the vegetables and fruits are completely located in the vegetable and fruit basket, that is, the vegetables and fruits are located below the second barrier screen 222, the second barrier screen 222 is closed, and the vegetables and fruits are all enclosed in the vegetable and fruit basket. The first driving device 400 drives the basket loading device 200 to descend as a whole, and the first barrier screen 104 is opened. When a preset number of fruits and vegetables reach the collecting portion 220, the first barrier screen 104 is closed, and the basket loading device 200 loads a new layer of fruits and vegetables into baskets.

[0052] The working environment of the basket loading device of the present invention is a water tank for storing water. By adjusting the depth of the basket loading device immersed in water, the fruits and vegetables transmitted to the collection part are loaded into the fruit basket. The buoyancy of the water plays a good buffering role, avoiding the collision of adjacent layers of fruits and vegetables during the basket loading process, and effectively achieving loss reduction.
