Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1 to 6 As shown, this embodiment provides a screening device for brewing fruit wine, including a frame 1, a shell 2 is installed on the frame 1, a hopper 4 is connected to the top of the shell 2, a dividing mechanism is provided below the hopper 4, the dividing mechanism is installed on the top surface of the shell 2, a wind selection mechanism is provided below the dividing mechanism, the wind selection mechanism is installed on the shell 2, an impurity screening mechanism is provided below the wind selection mechanism, a multi-stage screening mechanism is provided on the discharge side of the impurity screening mechanism, an impurity collecting box 13 is provided at the bottom of the shell 2, and the impurity collecting box 13 is connected to the bottom of the shell 2.

[0028] When the present invention is used, the fruit to be screened is put into the hopper 4, and is sent into the interior of the outer shell 2 after passing through the material dividing mechanism. The air separation mechanism separates the lighter impurities in the fruit, and the fruit continues to fall onto the impurity screening mechanism and is screened by the impurity screening mechanism. The heavier impurities in the fruit are screened and fall, and the fruit is sent to the multi-stage screening mechanism, and is screened and sorted by the multi-stage screening mechanism into fruits of different sizes for brewing fruit wine.

[0029] A further optimized solution is that the material dividing mechanism includes a material dispensing roller 5, which is rotatably connected in the outer shell 2, one end of the material dispensing roller 5 passes through the side wall of the outer shell 2 and is transmission-connected to a material dispensing roller motor 501, the material dispensing roller motor 501, and a plurality of material dispensing plates 502 are evenly spaced around the outer side of the material dispensing roller 5, and the outer contours of the material dispensing roller 5 and the plurality of material dispensing plates 502 match the discharge port of the hopper 4.

[0030] By controlling the rotation of the feeding roller motor 501, the feeding roller motor 501 drives the feeding roller 5 to rotate, and the feeding plate 502 on the feeding roller 5 feeds the fruit into the shell 2. Considering that the feeding plate 502 will squeeze the fruit during the rotation process, the feeding plate 502 can be replaced with a flexible material such as rubber.

[0031] A further optimized solution is that the air selection mechanism includes a light material outlet 201 opened on the side wall of the outer shell 2, and an air inlet 202 is provided on the opposite side of the light material outlet 201. The air inlet 202 is opened on the side wall of the outer shell 2, and the air inlet 202 is connected to the air outlet of the blower 3. The blower 3 is installed on the outer wall of the outer shell 2, and the light material outlet 201 is connected to the light material channel 6.

[0032] The blower 3 is running, and air flows in from the air inlet 202. When the fruit falls, it falls along with impurities.

[0036] The particle size passing through the net bag 9 is smaller than the smallest fruit particle size. The inclination angle of the net bag 9 can be adjusted by controlling the extension and contraction amount of the telescopic rod 902. The cam motor 905 is controlled to rotate, and the cam motor 905 drives the cam 904 to rotate. Since the cam 904 and the sliding plate 903 are arranged in a contact manner, the net bag 9 will vibrate accordingly, and the impurities in the fruit will be screened through the net bag 9, and the fruit without impurities will enter the multi-stage screening mechanism.

[0037] A further optimized solution is that the multi-stage screening mechanism includes a plurality of conveyor belt screening mechanisms 11 arranged in sequence along the material conveying direction. The conveyor belt screening mechanism 11 at the head end is located below the lower end of the sliding plate 10.

[0039] By controlling the driving motor 103 to rotate, the driving motor 103 drives the conveyor belt 1101 to run, ensuring that the subsequent relatively large fruits continue to be transported backwards.

[0041] A further optimized solution is provided, in which the equal-spacing adjustment mechanism includes a plurality of intermediate hinged rods 14, the middle parts of every two intermediate hinged rods 14 are hinged, the ends of the two intermediate hinged rods 14 are hinged to the ends of the other two intermediate hinged rods 14, the ends of the two intermediate hinged rods 14 close to the spacing adjustment motor 102 are respectively hinged to one end of a first end hinged rod 1401 and a second end hinged rod 1402, the other ends of the first end hinged rod 1401 and the second end hinged rod 1402 are hinged to each other, and are rotatably connected to a spacing adjustment block 1105 close to the spacing adjustment motor 102, the middle hinge points of the two intermediate hinged rods 14 are respectively rotatably connected to other spacing adjustment blocks 1105, the ends of the two intermediate hinged rods 14 far away from the spacing adjustment motor 102 are respectively hinged to a third end hinged rod 1403 and a fourth end hinged rod 1404, the other ends of the third end hinged rod 1403 and the fourth end hinged rod 1404 are hinged to each other, and are rotatably connected to the conveyor belt support plate 101.

[0042] By controlling the rotation of the spacing adjustment motor 102, the spacing adjustment motor 102 drives the spacing adjustment block 1105 to move. Since the first end hinged rod 1401, the second end hinged rod 1402, the third end hinged rod 1403, the fourth end hinged rod 1404 and the middle hinged rod 14 are hingedly arranged, the other spacing adjustment blocks 1105 will move with equal intervals.
