Description

Technical Field

[0001] This utility model relates to the field of fruit processing technology, and in particular to a device for extracting pear juice. Background Technology

[0002] Pear juice is a beverage made primarily from pears. It offers various health benefits and has a wide range of applications. It is obtained by chopping, pressing, and filtering pears.

[0003] Chinese patent document CN218256944U discloses an extraction device for pear juice, relating to the field of raw material extraction technology. The extraction device includes a support platform with legs at its bottom. An extrusion mechanism is mounted on the support platform, and a fixed bracket is located on the side of the support platform near the feed inlet of the extrusion mechanism. A crushing mechanism connected to the feed inlet of the extrusion mechanism is located within the fixed bracket, and a pressurizing mechanism is connected to the discharge outlet of the extrusion mechanism. The advantages of this invention are: by first crushing the fruit, then extruding it through a screw extruder, and finally pressing it with a pressurizing mechanism, the extraction speed of the juice is accelerated. Furthermore, after crushing and extrusion, the juice can be extracted without applying excessive pressure or maintaining it for a prolonged period, thus improving work efficiency.

[0004] The existing technology has the following problems:

[0005] The extraction device directly places the pears into the crushing mechanism, which lacks a sealing mechanism. Since the pears will oxidize after crushing, some pear fragments will remain after the crushing equipment crushes the pears. These fragments, after oxidation, will affect the taste of the pear juice produced later. Utility Model Content

Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, an extraction device for pear juice includes a support frame 1, an extrusion mechanism 2 is movably installed on the inner side of the support frame 1, a processing cylinder 3 is movably installed on the upper side of the extrusion mechanism 2 near the left side, a crushing mechanism 4 is movably installed on the inner side of the processing cylinder 3, a sealing mechanism 5 is rotatably connected to the upper side of the processing cylinder 3, and a squeezing mechanism 6 is provided on the right side of the extrusion mechanism 2.

[0028] The enclosed mechanism 5 includes a turntable 51, the lower side of which is rotatably connected to the upper side of the processing cylinder 3. Several annularly distributed feeding platforms 52 are fixedly connected to the outer side of the processing cylinder 3. A rotating assembly 53 is movably installed on the outer side of the processing cylinder 3 near the upper side. Several annularly distributed airbag rings 54 are embedded in the lower side of the turntable 51 near the edge. Several annularly distributed temporary storage components 55 are fixedly connected to the upper side of the turntable 51 near the edge.

[0029] It should be noted that the structural design of the components contained in the extrusion mechanism 2 and the crushing mechanism 4 is consistent with the structural design of the components with the same function in the reference case. The rotating component 53 contains a motor for driving the turntable 51 to rotate. The temporary storage component 55 is used to put pears in. When putting pears in, the temporary storage component 55 is offset from the feeding platform 52. When the pears in the temporary storage component 55 are put into the processing cylinder 3, the temporary storage component 55 and the feeding platform 52 are aligned. The air bag ring 54 is used to seal the upper side between the turntable 51 and the processing cylinder 3.

[0030] like Figure 3 , Figure 5 As shown, the temporary storage component 55 includes a feed cylinder 551. The lower side of the feed cylinder 551 is fixedly connected to the upper side of the turntable 51 near the edge. Two annularly distributed first telescopic rods 552 are fixedly connected to the outer side of the feed cylinder 551. A rotating plate 553 is rotatably connected to the upper end of each of the two first telescopic rods 552. Gears 554 are fixedly connected to the bottom of the two rotating plates 553 on the side that are close to each other. Racks 555 are meshed with the sides of the two gears 554. The racks 555 are slidably connected to the outer side of the feed cylinder 551 on the side that are close to each other. A sealing cover 557 is fixedly connected to the upper side of the rotating plate 553.

[0031] It should be noted that the first telescopic rod 552 is an electric push rod that can drive the rotating plate 553 to move up and down. When the rotating plate 553 moves up, it drives the gear 554 to move up. Since it meshes with the rack 555, the rotating plate 553 drives the sealing cover 557 to rotate, opening the upper side of the feed cylinder 551 for feeding pears. The reverse operation is used to seal the feed cylinder 551. A vent pipe can be installed on the sealing cover 557 to replace the gas in the feed cylinder 551 with nitrogen, further reducing the impact of oxidation.

[0032] like Figure 5 As shown, a second telescopic rod 556 is fixedly connected to the upper side of each of the two racks 555, and the outer side of the second telescopic rod 556 is fixedly connected to the outer side of the feed cylinder 551 near the upper side.

[0033] It should be noted that the second telescopic rod 556 is an electric push rod that can drive the rack 555 to move up and down. This allows the rack 555 to move synchronously with the rotating plate 553 in the initial stage when the first telescopic rod 552 drives the rotating plate 553 to move up, thus avoiding interference between the rack 555 and the feed cylinder 551 caused by the direct rotation of the rotating plate 553.

[0034] like Figure 3 As shown, torsion springs are provided at the lower ends of the two rotating plates 553 and on the upper side of the first telescopic rod 552.

[0035] It should be noted that the torsion spring is used to stabilize the rotating plate 553, so that the rotating plate 553 remains vertical when it is not subjected to other external forces.

[0036] like Figure 6 As shown, the extrusion mechanism 6 includes a processing box 61, an extrusion assembly 62 is movably mounted on the upper side of the processing box 61, a support platform 63 is fixedly connected to the bottom inner side of the processing box 61, and a filter screen 64 is attached to the upper side of the support platform 63.

[0037] It should be noted that the component structure on the extrusion assembly 62 is consistent with the component structure of the same function in the reference case. The support platform 63 is used to support the filter screen 64. The filter screen 64 has a through hole on its upper side and a slot through the left and right sides on its lower side.

[0038] like Figure 6 As shown, four rectangularly distributed third telescopic rods 65 are fixedly connected to the bottom inner side of the treatment box 61 near the four corners. The upper side of the third telescopic rods 65 is fixedly connected to the lower side of the filter screen 64 near the four corners. Two fourth telescopic rods 66 are fixedly connected to the bottom left and right sides of the treatment box 61. A baffle 67 is fixedly connected to the upper side of the fourth telescopic rod 66. A scraper 68 is fixedly connected to the rear side of the baffle 67 near the left and right sides via a round rod.

[0039] It should be noted that the third telescopic rod 65 and the fourth telescopic rod 66 are electric push rods that can drive the filter screen 64 to move up and down. When the filter screen 64 moves to the top, the fourth telescopic rod 66 drives the baffle 67 to move forward, so that the baffle 67 drives the scraper 68 to automatically remove the material on the filter screen 64 from the inside of the processing box 61.

[0040] like Figure 6 As shown, the lower inner surface of the processing box 61 is an inclined surface that slopes to the lower right.

[0041] It should be noted that the sloping bottom of the inner side of the processing box 61 causes the pear juice falling to the bottom of the inner side of the processing box 61 to automatically flow to the right.

[0042] The working principle of this utility model is as follows: First, the rotating assembly 53 contains a motor to drive the turntable 51 to rotate. The temporary storage assembly 55 is used to put pears in. During the feeding process, the temporary storage assembly 55 is offset from the feeding platform 52. When the pears in the temporary storage assembly 55 are put into the processing cylinder 3, the temporary storage assembly 55 and the feeding platform 52 are aligned. The airbag ring 54 is used to seal the upper side between the turntable 51 and the processing cylinder 3. The first telescopic rod 552 is an electric push rod that can drive the rotating plate 553 to move up and down. When the rotating plate 553 moves up, it drives the gear 554 to move up. Because it meshes with the rack 555, the rotating plate 553 drives the sealing cover 557 to rotate, opening the upper side of the feeding cylinder 551 for pear feeding. The reverse operation is used to seal the feeding cylinder 551. A vent pipe can be set on the sealing cover 557 to replace the gas in the feeding cylinder 551 with nitrogen, further reducing oxygen. To mitigate the oxidation effect, the feeding cylinder 551 is sealed by the sealing cover 557 and the turntable 51. This ensures that the processing cylinder 3 is sealed when pears are fed into the feeding cylinder 551, and the lower seal on the feeding cylinder 551 opens when pears are placed into the processing cylinder 3. This keeps the processing cylinder 3 sealed at all times, preventing contact with air and oxidation of the pears. Finally, the third telescopic rod 65 and the fourth telescopic rod 66 are electric push rods that can move the filter screen 64 up and down. When the filter screen 64 moves to the top, the fourth telescopic rod 66 moves the baffle 67 forward, causing the baffle 67 to drive the scraper 68 to automatically remove the material on the filter screen 64 from the inside of the processing box 61. By using a liftable filter screen 64, the scraper 68 can automatically discharge the pear residue on the filter screen 64 from the inside of the processing box 61, preventing pear residue from remaining in the processing box 61 and affecting the subsequent extraction of pear juice.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
