[0031] like Figure 2 and Figure 5 As shown, the screen 10 is an inverted truncated cone structure with a hollow interior. Screen holes for screening fruit and vegetable washing salt are opened on the side walls of the screen 10. The inverted truncated cone structure cooperates with the stirring mechanism 9 to facilitate the screened fruit and vegetable washing salt to fall into the discharge guide mechanism 11 through the screen holes. A crushing table 1001 is fixedly connected to the bottom of the screen 10. Through the inverted truncated cone structure, large salt blocks that cannot pass through the screen holes will fall onto the crushing table 1001, which is convenient for the stirring mechanism 9 to crush them.

[0032] like Fig. 9As shown, the stirring mechanism 9 includes a stirring shaft 901, the upper end of the stirring shaft 901 passes through the cover plate 1 and is connected to the stirring motor 2, the stirring motor 2 is fixedly connected to the cover plate 1, and the side wall of the stirring shaft 901 is fixed with a first stirring rod 902 and a second stirring rod 903 arranged up and down, and the first stirring rod 902 and the second stirring rod 903 are four in number, and the four first stirring rods 902 and the four second stirring rods 903 are evenly distributed on the outer side wall of the stirring shaft 901, and the first stirring rod 902 and the second stirring rod 903 are evenly distributed on the outer side wall of the stirring shaft 901. 03 A scraper plate 905 is fixed to one end away from the stirring shaft 901.

The first stirring rod 902 and the second stirring rod 903 cooperate with the corresponding scraper plates 905. During the stirring process, the fruit and vegetable washing salt can be driven to move toward the side wall of the screen 10. The first stirring rod 902 and the second stirring rod 903 are arranged up and down, so that the fruit and vegetable washing salt above and below can be screened at the same time, which greatly improves the screening efficiency.

[0034] like Figure 2 and Figure 5 As shown, the discharge guide mechanism 11 is a truncated cone structure with a hollow interior, and a plurality of evenly distributed dividing plates 1101 are fixedly connected to the discharge guide mechanism 11, and the number of the dividing plates 1101 is the same as the number of the dividing bins 5. Adjacent dividing plates 1101 are respectively sealed and fixedly connected to the two ends of the corresponding dividing bins 5, and a sealing plate is provided on the top of the dividing bin 5. The dividing plates 1101 isolate the dividing bins 5 to facilitate subsequent quantitative discharge.

[0035] In this embodiment, the discharging mechanism 6 is composed of six groups, such as Figure 4 and Figure 8As shown, the discharging mechanism 6 includes a slide plate 601, and a guide rod 604 is fixed at one end of the slide plate 601. The guide rod 604 passes through the long guide groove 503 on the fixed plate 502 and the corresponding arc guide groove 1201 on the rotating plate 12 in sequence. The guide rod 604 cooperates with the arc guide groove 1201 and the long guide groove 503. The bottom of the slide plate 601 is fixedly connected to a barrel 602, which passes through the slide plate 601, and through holes 603 are provided at the upper and lower ends of the barrel 602. The bottom of the barrel 602 is rotatably connected to a bottom cover 605 that can block the through hole 603. The bottom cover 605 has a certain dead weight and can be opened automatically.

By controlling the sliding of the slide plate 601, when the barrel 602 is aligned with the discharge port 501, quantitative discharge is achieved, and when the slide plate 601 drives the barrel 602 to slide away, the slide plate 601 can block the discharge port 501 to prevent leakage.

[0037] Four support legs 8 are fixed at the bottom of the material distribution bin 5, and a support platform 14 is fixedly connected to the support legs 8.

The output end of the discharging motor 13 is provided with a rotating shaft 1301. The middle of the fixed disk 502 is provided with a hole for the rotating shaft 1301 to pass through. The rotating shaft 1301 passes through the support column 1401 and the fixed disk 502 in turn, and is fixedly connected to the rotating disk 12. Through the forward and reverse rotation of the discharging motor 13, the guide rod 604 in the discharging mechanism 6 can move back and forth along the long strip guide groove 503, thereby realizing the synchronous movement of multiple groups of discharging mechanisms 6 for quantitative discharging.

[0038] Working principle:

[0039] When in use, fruit and vegetable washing salt is put into the screening tank 4 through the feed inlet 3, and the fruit and vegetable washing salt falls onto the screen 10, and the stirring motor 2 and the discharge motor 13 are started. The stirring motor 2 drives the stirring shaft 901, the first stirring rod 902, the second stirring rod 903 and the crushing rod 904 to rotate. The first stirring rod 902 and the second stirring rod 903 cooperate with the scraper plate 905. During the stirring process, the fruit and vegetable washing salt is stirred to the side wall of the screen 10, so that the fruit and vegetable washing salt is screened through the screen, and large pieces of salt blocks directly fall onto the crushing table 1001. As the crushing rod 904 rotates, the large pieces of salt blocks are pressed into the bottom of the crushing rod 904. As the crushing rod 904 continues to rotate, the distance between the side of the crushing rod 904 and the salt blocks is continuously reduced, so that the crushing rod 904 with a V-shaped structure grinds and crushes the salt blocks, thereby breaking up the salt blocks. The broken salt blocks are thrown to the side wall of the screen 10 under the centrifugal effect of the rotation of the crushing rod 904, so that they are screened again.

[0040] The screened fruit and vegetable washing salt falls onto the discharging guide mechanism 11. Since the side of the discharging guide mechanism 11 is tilted downward, the fruit and vegetable washing salt gradually slides into each sub-bin 5. The discharging motor 13 can drive the rotating disk 12 to rotate forward or reverse. During the rotation, the arc guide groove 1201 drives the guide rod 604 in the discharging mechanism 6 to move back and forth along the long guide groove 503, thereby driving the slide plate 601 to slide back and forth along the slide rail 504. When the slide plate 601 drives the barrel 602 to align with the discharge port 501, at this time, the bottom cover 605 blocks the bottom of the barrel 602 under the action of the material blocking seat 505, and the fruit and vegetable washing salt in the sub-bin 5 falls into the barrel 602 through the discharge port 501 until the barrel 602 is filled with fruit and vegetable washing salt; then the slide plate 601 drives the barrel 602 to slide to the side of the discharge hopper 7, and a packaging bag is provided at the bottom of the discharge hopper 7. As the discharge hopper 7 no longer interferes with the bottom cover 605, the bottom cover 605 opens under the action of its own weight, and the fruit and vegetable washing salt falls into the discharge hopper 7 and enters the packaging bag, completing the fixed material discharge packaging.

[0041] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
