DETAILED DESCRIPTION

[0026] In this embodiment, the top of the frame 1 is fixedly connected to the funnel 6, the inner side of the funnel 6 is rotatably connected to the turntable 7, and the bottom of the turntable 7 is fixedly connected to the motor 2 4.

[0027] By providing the turntable 7, the fruits can be placed in the tray 12 in an orderly manner, so that they can be screened according to weight.

[0028] In this embodiment, a spiral protrusion is provided on the top of the rotating disk 7, and a circular hole is opened on the bottom of the funnel 6.

[0029] The turntable 7 forms a one-way channel through the spiral protrusions, so that the fruits are evenly arranged after falling from the funnel 6.

[0030] In this embodiment, a groove-shaped protrusion is provided at the bottom of the tray 12, and the sliding block 13 has a T-shaped shape.

[0031] The slider 13 can slide along the groove-shaped protrusion at the bottom of the tray 12 under the action of the push rod 14, so as to adapt to the position change of the tray 12 after being subjected to force.

[0032] In this embodiment, two block-shaped protrusions are provided on one side of the bottom of the tray 12 , a clamp-shaped protrusion is provided on the other side of the bottom of the tray 12 , and a circular protrusion is provided on the top of the movable plate 15 .

[0033] The tray 12 is connected to the fixing plate 18 via the clamp-shaped protrusion at the bottom, and rotates around the connection with the fixing plate 18 after receiving the force of the top rod 14 .

[0034] In this embodiment, a square hole is formed on the top of the fixing plate 18 , and round holes are formed on both sides of the fixing plate 18 .

[0035] The push rod 14 can slide in the square hole of the fixing plate 18 , and the two guide pillars 16 can slide in the round holes of the fixing plate 18 .

[0036] In this embodiment, a circular protrusion is provided at the bottom of the top rod 14 , the outer shape of the inclined plate 11 is a right-angled trapezoid, and a rod-shaped protrusion is provided at the rear of the inclined plate 11 .

[0037] The circular protrusion of the push rod 14 will move upward after being squeezed by the inclined plate 11, and the force will be transmitted to the tray 12 through the slider 13 to tilt it.

[0038] It should be noted that the utility model is a fruit screening device, which can place fruits in the tray 12 in an orderly manner when in use. The specific implementation method is to start the motor 2 4, the motor 2 4 drives the turntable 7 to rotate together, and pour the fruits into the top of the funnel 6. The fruits enter the top of the turntable 7 through the funnel 6. The fruits will enter the spiral channel of the turntable 7 under the centrifugal force of the rotation of the turntable 7;

[0039] The fruits that fall down subsequently will enter the spiral channel in sequence under the action of centrifugal force. The fruits at the end of the channel will fall down when they rotate to the notch in the front of the funnel 6. By controlling the rotation speed between the motor 2 4 and the motor 1 3, the falling fruits can fall into the tray 12.

[0040] By rotating the motor 3, the driving wheel 8 can be rotated, and the driving wheel 8 drives the driven wheel 9 to rotate together through the belt 10. When the belt 10 rotates, it will drive the fixed plate 18 connected thereto to move, and the fixed plate 18 drives the movable plate 15 and the tray 12 to rotate together. When the fruit falls into the tray 12, the tray 12 is pressed down. During the downward movement of the tray 12, the movable plate 15 and the guide column 16 are driven to move downward together. After the movable plate 15 moves downward, the spring 17 is compressed, and when the tray 12 moves downward, the ejector rod 14 is driven to move downward together;

[0041] After the tray 12 drives the fruit to move a certain distance, the bottom of the pushed-down push rod 14 will contact with a certain inclined plate 11 and move upward under the pressure of the inclined surface of the inclined plate 11. The push rod 14 transmits the force to the tray 12 through the slider 13 to make it tilt. After the tray 12 tilts a certain angle, the fruit placed on the top will roll down into the blanking plate 2. During the tilting process of the tray 12, the slider 13 will slide along the groove at its bottom to adapt to the relative position change of the tray 12 when it tilts. The slider 13 will stretch the tension spring 19 while sliding. When the push rod 14 moves out of the range of the inclined plate 11, the slider 13 will reset under the action of the tension spring 19 and drive the push rod 14 to reset. When the push rod 14 resets and moves downward, it drives the tray 12 to reset so that it will return to a horizontal state. Due to the loss of the pressure of the fruit, the movable plate 15 will move up and reset under the action of the spring 17.

[0042] The tops of several inclined plates 11 are at the same height. When the tray 12 is in an empty state, the bottom of the top rod 14 is higher than the height of the inclined plates 11, so it can pass through different inclined plates 11 smoothly. The bottoms of several inclined plates 11 are at different heights. When the tray 12 bears different weights, the bottoms of the top rod 14 will be at different heights. After the top rod 14 moves a certain distance, it will contact the inclined surface of the inclined plate 11 in the same height range, and rise up and down under the pressure of the inclined surface, thereby completing the screening of fruits of different weights;

[0043] By providing the screening mechanism 5, the screening device can arrange the fruits in an orderly manner and place them in the tray 12, and can screen the fruits according to different weights, thereby increasing the efficiency of screening and feeding, saving manpower, and reducing equipment costs.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
