[0026] Example:
[0027] As attached Figure 1 To Attachment Figure 4 As shown:
[0028] The utility model provides a screening machine for fruit and vegetable processing, comprising a base 1, an electric telescopic rod 2 is installed at the middle position of the top of the base 1, a tray 3 is installed at the top of the electric telescopic rod 2, three recovery boxes 4 are installed at the top of the tray 3, a cylinder 5 is installed at the top of the base 1 at a position directly above the tray 3 through a bracket, a through groove 6 is provided at the top of the cylinder 5, a limiting ring 7 is installed at the peripheral side of the bottom end of the through groove 6, a screening plate 8 is slidably installed inside the through groove 6, a plurality of tension springs 9 are installed at the peripheral side of the bottom end of the screening plate 8, and the other end of the tension spring 9 is connected to the top of the limiting ring 7, a cam 10 is rotatably installed at the bottom end of one side of the through groove 6 at a position directly below the screening plate 8, a cover plate 11 is installed at the top of the cylinder 5, a stirring mechanism is installed at the bottom end of the cover plate 11, and a feed port 12 is provided at one side of the top of the cover plate 11.
[0029] Among them, the screening plate 8 includes a first screen 801, a second screen 802 and a third screen 803, which are arranged in a circle in the through groove 6, and the areas of the first screen 801, the second screen 802 and the third screen 803 are the same, and the mesh numbers of the first screen 801, the second screen 802 and the third screen 803 decrease successively. When fruits and vegetables of different sizes are moved to the first screen 801, the second screen 802 and the third screen 803 respectively, the fruits and vegetables matching the corresponding screen mesh size will pass through the screen and fall into the recovery box 4 directly below to achieve screening.
[0030] Among them, the feed port 12 is located directly above the first screen 801, which is convenient for conveying the fruit and vegetable raw materials to be screened from the feed port 12 to the first screen 801 for screening. Since the first screen 801 has the largest mesh number, smaller fruits and vegetables will fall first, and larger fruits and vegetables will remain on the surface of the first screen 801, waiting for subsequent screening.
[0031] The three recycling boxes 4 are respectively located directly below the first sieve 801 , the second sieve 802 and the third sieve 803 , so as to facilitate the recycling of the sieved fruits and vegetables.
[0032] Among them, a first motor 13 is installed at the bottom end of one side of the cylinder 5, and the output end of the first motor 13 is connected to the cam 10 through a coupling. The first motor 13 drives the cam 10 to rotate, so that the cam 10 can continuously lift the screening plate 8. With the reset pulling action of the tension spring 9, the screening plate 8 vibrates continuously, which is convenient for shaking out and screening the accumulated fruits and vegetables.
[0033] Among them, the stirring mechanism includes a central shaft 14, which is rotatably mounted on the bottom end of the cover plate 11, and three push plates 15 are equidistantly mounted on the circumference of the bottom end of the central shaft 14. The bottom end of the push plate 15 is close to the top of the screening plate 8, and the other end of the push plate 15 is close to the circumference of the through groove 6. The push plate 15 can push the fruit and vegetable raw materials on the surface of the screening plate 8 to the position of the next screen for secondary screening, thereby realizing the screening of fruits and vegetables of different sizes.
[0034] A second motor 16 is installed at the top of the cover plate 11 , and an output end of the second motor 16 is transmission-connected to the central shaft 14 via a coupling. The motor drives the central shaft 14 to rotate, thereby driving the push plate 15 to rotate.
[0035] A controller 17 is installed on one side of the top of the base 1 to facilitate control of the entire circuit of the screening machine.
[0036] The working principle of this embodiment is as follows: the staff first controls the electric telescopic rod 2 to extend so that the tray 3 is close to the bottom end of the cylinder 5, and then puts the fruit and vegetable raw materials to the top of the screening plate 8 through the feed port 12, so that the fruit and vegetable raw materials stay on the top of the first screen 801. At this time, the fruits and vegetables that match the size of the first screen 801 will pass through the first screen 801 and fall into the recovery box 4. When the fruits and vegetables on the top of the first screen 801 are piled up, the first motor 13 is turned on, and the first motor 13 drives the cam 10 to rotate, so that the cam 10 can continuously lift the screening plate 8, and cooperate with the reset pulling action of the tension spring 9, the screening plate 8 is constantly vibrating, which is convenient for the accumulated fruits and vegetables to be removed. The fruits and vegetables are shaken and screened. After the first screening is completed, the second motor 16 is turned on, and the second motor 16 drives the central shaft 14 to rotate, and then drives the push plate 15 to rotate, so that the push plate 15 pushes the fruit and vegetable raw materials to move to just above the second screen 802, and the first motor 13 is turned on again to drive the screening plate 8 to vibrate. After the second screening is completed, the second motor 16 is turned on, so that the push plate 15 pushes the fruit and vegetable raw materials to move to just above the third screen 803 and controls the screening plate 8 to vibrate, so as to achieve the screening of fruits and vegetables, and then achieve the screening of fruit and vegetable raw materials of different sizes. After all the screening is completed, the electric telescopic rod 2 is controlled to retract, and the recycling box 4 is removed to complete the recycling.
