Description

Technical Field

[0001] The utility model relates to the technical field of grape juice processing, in particular to a grape pulping and air selection device. Background Art

[0002] In the grape wine industry, grapes are usually first pulped and then fermented to make wine and brandy. During the grape processing, impurities such as grape leaves and small fruit branches are usually removed manually or by wind selection devices, and the wind selection device is usually installed between the conveying device and the pulping device.

[0003] The existing wind selection device, when in use, usually utilizes the wind generated by the fan to remove impurities from the grapes. Since the grapes are uneven in size during their growth, and the wind generated by the fan is very strong when working, some small grapes will be blown away along with the impurities, and then the staff will select the small grapes from the impurities. This operation is troublesome and increases the labor intensity of the staff. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 In the embodiment of the utility model, a grape pulping and air selection device comprises a screening box 1 with an open top surface, a cleaning mechanism 2 is arranged on the top surface of the screening box 1, a vibrating mechanism 3 is arranged inside the screening box 1, L-shaped support blocks 11 are fixedly connected to both sides of the top of the two opposite side surfaces of the screening box 1, a feed hopper 12 connected to the inside of the screening box 1 is fixedly connected to one side of the screening box 1, an L-shaped plate 13 is fixedly connected between the two opposite side surfaces inside the screening box 1, a plurality of fans 14 are fixedly arranged at equal intervals on the side of the L-shaped plate 13 corresponding to the open side of the screening box 1, and the cleaning mechanism 2 comprises two symmetrical L-shaped support blocks 11 respectively located at opposite positions. The outer walls of the two round rollers are rollingly connected with a conveyor belt 21 of a mesh structure, a sponge 22 is arranged inside the conveyor belt 21, and a plurality of hard tubes are fixed at equal intervals inside the sponge 22, wherein one end of a hard tube located in the middle is fixedly connected with a four-way tube 23, and one end of the other plurality of hard tubes is fixedly connected with a three-way tube 24, both ends of the four-way tube 23 are fixedly connected with connecting tubes which are fixed to the plurality of three-way tubes 24 at corresponding positions and are internally interconnected, one end of the connecting tube is fixed to the L-shaped support block 11 at the corresponding position, a suction pump 25 is fixedly connected to one side of the screening box 1, and a hose 26 is fixedly connected between the suction pump 25 and the four-way tube 23.

[0023] Specifically, the device is first fixed between the inclined conveying device and the pulping device, and the feed hopper 12 is located directly below the discharge end of the conveying device. When the conveying device pours the grapes to be processed from the feed hopper 12 into the interior of the screening box 1, the grapes will fall onto the vibration mechanism 3, and multiple fans 14 and suction pumps 25 are started at the same time. The wind produced by the fans 14 can blow away some impurities such as grape leaves and small fruit branches in the grapes. Since the multiple fans 14 are located below the vibration mechanism 3, the multiple fans 14 can blow the impurities in the grapes to the conveyor belt 21. The started suction pump 25 can form a negative pressure on the surface of the sponge 22. When the impurities are blown by the multiple fans 14 to the conveyor belt 21, since the conveyor belt 21 is a mesh structure, the surface of the conveyor belt 21 is also in a negative pressure state, so that the impurities can be adsorbed on the surface of the conveyor belt 21. Since the wind generated by the multiple fans 14 is relatively strong, some small-grained grapes will be blown into contact with the conveyor belt 21. However, the surface of the grapes is relatively smooth, so it is difficult for the grapes to be adsorbed on the conveyor belt 21. At this time, the small-grained grapes are always suspended and in contact with the surface of the conveyor belt 21 under the action of the multiple fans 14, and then the conveyor belt 21 can be rolled by the rotation of the round roller. The rolling conveyor belt 21 can transport the impurities adsorbed on its bottom surface to the outside of the screening box 1, and then the impurities fall at the end of the conveyor belt 21 that contacts the round roller away from the feed hopper 12, and some large-grained grapes slide to the bottom of the screening box 1 under the action of the vibration mechanism 3, and fall into the pulping device. When all the grapes are transported, the multiple fans 14 are turned off. At this time, the small-grained grapes suspended in the screening box 1 fall to the bottom of the screening box 1 under the action of their own gravity.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a side of the screening box 1 away from the feed hopper 12 is fixedly connected with a collecting bin 15 , the length of the sponge 22 is less than the distance between the two round rollers, and the length of the sponge 22 is greater than the length of the top surface of the screening box 1 .

[0026] In this embodiment, since the sponge 22 is located between the two round rollers and the two ends of the sponge 22 are located outside the screening box 1, when the impurities adsorbed on the conveyor belt 21 move to the round roller close to the collecting bin 15, due to the obstruction of the round roller, the surface of the conveyor belt 21 in contact with the round roller does not form a negative pressure or forms a very small negative pressure, so the impurities adsorbed on the conveyor belt 21 fall into the collecting bin 15 under the action of their own gravity.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, some heavier impurities in the grapes are cleaned out and the grapes are prevented from pressing the impurities in the grape leaves.

[0029] like Figure 2 and Figure 5 As shown, in this embodiment, one end of one of the round rollers is fixedly connected to a connecting shaft that rotates through the L-shaped support block 11 at the corresponding position, and the outer wall of the connecting shaft is fixedly connected to a pulley 27. The vibration mechanism 3 includes a round rod located between two opposite side surfaces inside the screening box 1 and rotating near the feed hopper 12, and a screen 31 is fixedly connected to the outer wall of the round rod. A pad is fixedly connected to one side of the screening box 1. A rotating rod is rotatably connected between two opposite side surfaces inside the screening box 1 and located inside the L-shaped plate 13. Cams 32 are fixedly connected to both ends of the outer wall of the rotating rod. One end of the screening box 1 is rotatably and fixedly connected to a pulley 23 which is driven by a belt with pulley 1 27, the top surface of the pad is fixedly connected to a motor 34, the output end of the motor 34 is fixed to a rotating rod, and baffles 16 in contact with the end of the screen 31 are fixedly connected to the opposite sides of the interior of the screening box 1 and located below one end of the screen 31, a discharge port 17 is penetrated through the inner bottom surface of the screening box 1 and located between the baffle 16 and the inner side surface of the screening box 1, a through hole is penetrated through the bottom end of one side of the screening box 1, and a collecting box 18 is slidably sleeved inside the through hole.

[0030] In this embodiment, the pulley 2 33 and the rotating rod can be rotated by driving the motor 34. The rotating pulley 2 33 can make the conveyor belt 21 roll between the two round rollers. The rotating rotating rod can make the cam 32 drive the screen 31 to vibrate back and forth along the axis of the round rod, so that the grapes falling on the screen 31 can vibrate up and down. The up and down vibrating grapes can make some heavier impurities mixed in them fall from the screen 31 into the collecting box 18, and the up and down vibrating screen 31 can disperse the grapes, which can prevent the grapes from pressing the impurities such as grape leaves, so that it is convenient for multiple fans 14 to blow the grape leaves to the conveyor belt 21.
