Description
Technical Field
[0001] This invention relates to the field of wine production and processing technology, and in particular to a grape crushing and juicing device for winemaking. Background Technology
[0002] Grapes are among the summer fruits richest in complex iron, making them a nutritious food for people with anemia. Grapes are also high in vitamins, which helps strengthen the body and boost immunity. The juice extracted from grape pulp also has rich nutritional and economic value; it is frequently used for fermentation to make wine, brandy, or whiskey.
[0003] The grape juicing device for wine production, disclosed in CN 218321288 U, facilitates the removal of the first and second pressing plates and the fixed frame through the arrangement of a fixed frame, a fixed plate, a connecting rod, a connecting plate, and a cover plate. This allows for easy cleaning and prevents pulp from remaining in the installation box. The protrusions and grooves improve the crushing effect on the pulp, increasing the juicing output. The coordinated use of a moving plate, a filter plate, and a filter screen facilitates the filtration and separation of pulp from the juice, improving production efficiency. However, in actual processing, it still has some drawbacks. For example, it cannot separate and remove grape seeds during the juicing process. When juicing with grape seeds mixed in, the seeds are easily crushed, resulting in impurities in the grape juice and reducing the taste of the wine. Furthermore, the pressing structure is relatively simple, and a single pressing cannot guarantee complete extraction of grape juice, easily leading to waste. The automation level is low, resulting in low wine production. Therefore, it is necessary to propose a grape crushing and juicing device for wine production to solve these problems. Summary of the Invention
[0004] The purpose of this invention is to provide a grape crushing and juicing device for winemaking, which can automatically remove grape seeds, has a high degree of mechanization, and can thoroughly press the grapes.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a grape crushing and juicing device for winemaking, comprising a juicing chamber, a deseeding plate, a main pressing mechanism, and a filter plate arranged sequentially below the juicing chamber, a pushing member for controlling the lifting and lowering of the filter plate arranged below the filter plate, a secondary pressing mechanism arranged on the right side of the juicing chamber, and a scraping member for pushing the grapes after the initial pressing on the filter plate into the secondary pressing mechanism within the inner cavity of the juicing chamber, a juice collection chamber arranged at the bottom of the inner cavity of the juicing chamber, and a top... The device is equipped with a deseeding mechanism, which includes two L-shaped main frames fixedly connected to the top of the juicing chamber and symmetrically arranged on both sides. A deseeding chamber and a shaking mechanism that pushes the deseeding chamber to sway left and right are slidably arranged between the two L-shaped main frames. A grape placement rack and a feeding assembly are arranged inside the deseeding chamber. An L-shaped secondary frame is fixedly connected to the rear end face of the top of the juicing chamber. Two first electric push rods are fixedly installed on the top of the L-shaped secondary frame. A pressure plate is installed between the output ends of the two first electric push rods. Multiple sets of deseeding push needles are arranged at the bottom of the pressure plate.
[0006] By adopting the above technical solution, the staff first pours the washed grapes into the deseeding chamber in a measured amount. Then, the deseeding chamber is shaken left and right by a shaking mechanism, so that each grape is neatly placed into the grape placement rack. After the shaking stops, the first electric push rod is driven to push the pressure plate, causing the deseeding pusher to move down, align with the center of each grape, and push out the grape seeds inside. The grape seeds pass through the grape placement rack and fall onto the deseeding plate. The deseeding plate is then pulled out to clean the grape seeds. The pusher controls the filter plate to move up and fit tightly against the main pressing mechanism. Then, the feeding assembly pours the deseeded grapes onto the main pressing mechanism for juicing. The grape juice is filtered through the filter plate and falls into the juice collection chamber. The pusher then controls the filter plate to move down, so that the corresponding scraper sends the pressed grape skins and pulp into the secondary pressing mechanism for secondary pressing, so that the grape seeds are extracted more thoroughly. This not only increases the yield of grape juice but also improves the taste of the subsequent wine.
[0007] A further feature of the present invention is that the upper surface of the grape placement rack is provided with a plurality of grape placement slots at equal intervals, and the lower surface of the grape placement slots is provided with a seed discharge port corresponding to the seed removal pusher.
[0008] By adopting the above technical solution, during the shaking of the grape placement rack, each grape is dropped into the corresponding grape placement slot. After the deseeding needle passes through the grape, the grape seeds are also pushed out from the seed discharge port, causing the grape seeds to fall onto the deseeding plate under gravity.
[0009] A further configuration of the present invention is as follows: the shaking mechanism includes a connecting plate fixed to one side of the left L-shaped main frame, a first motor is mounted on the connecting plate, a cam that pushes the seed removal bin to the right is mounted on the output end of the first motor, two crossbars symmetrically arranged between the two L-shaped main frames are also provided, a push block that is slidably connected to the crossbars is fixedly connected to both the front and rear sides of the seed removal bin, a connecting spring is sleeved on the crossbar, the seed removal bin is located between the two crossbars, and the two ends of the connecting spring are respectively connected to the L-shaped main frame and the push block.
[0010] By adopting the above technical solution, the cam is rotated by the first motor. Since the push block slides horizontally on the crossbar, it can intermittently push the seed removal bin to the right, while squeezing the connecting spring. With the extension and rebound of the connecting spring, the seed removal bin shakes left and right continuously, thereby arranging the grapes neatly on the grape rack.
[0011] A further configuration of the present invention is as follows: the feeding assembly includes a second electric push rod installed on the left side wall of the inner cavity of the deseeding chamber, the output end of the second electric push rod is provided with a push-pull rod hinged to the bottom of the grape placement rack, and the left side of the grape placement rack is hinged to the inner wall of the deseeding chamber.
[0012] By adopting the above technical solution, after the grapes have been deseeded, the second electric push rod is driven to make the push-pull rod control the grape placement rack to rotate downwards, thereby tilting the grapes to facilitate subsequent pressing.
[0013] A further configuration of the present invention is as follows: the pushing member includes a second motor installed on the left side of the juicing chamber, the output end of the second motor is equipped with a bidirectional lead screw, a fixing rod is provided below the bidirectional lead screw, two sliding blocks are threaded on the outer side of the bidirectional lead screw, and an inclined rod hinged to the upper end of the sliding block is hinged to the bottom of the filter plate.
[0014] By adopting the above technical solution, the second motor controls the rotation of the bidirectional lead screw, which, under the restriction of the crossbar, pushes the sliding blocks on both sides to slide horizontally, and pushes the filter plate to rise through the inclined rod, so that it contacts the bottom of the pressing plate. This allows the grapes to fall smoothly into the gap between each connected pressing plate when they are poured, making it convenient for juicing.
[0015] A further feature of the present invention is that the deseeding plate is detachably installed inside the juicing chamber, and a filter screen is provided inside the deseeding plate, and a handle is fixedly connected to the right side of the deseeding plate.
[0016] By adopting the above technical solution, when grape seeds fall onto the filter screen, the grape juice mixed in drips downwards, and the seed removal plate can be pulled out as a whole by using the handle, making it easy to clean the grape seeds.
[0017] A further feature of the present invention is that the scraping component includes two third electric push rods installed on the left side wall of the juicing chamber, a push plate is installed between the output ends of the two third electric push rods, and a slag discharge port corresponding to the push plate is provided on the right side wall of the juicing chamber.
[0018] By adopting the above technical solution, the third electric push rod is driven to control the push plate to move to the right, so that the grape skin and pulp after pressing enter the secondary pressing mechanism for secondary pressing, which makes the device more automated and the juicing effect better.
[0019] A further configuration of the present invention is as follows: the main pressing mechanism includes a fourth electric push rod installed on the left and right side walls of the juicing chamber and a plurality of pressing plates horizontally and equidistantly arranged in the inner cavity of the juicing chamber. A telescopic frame is hinged to the front and rear sides of each pair of connected pressing plates. The front and rear end faces of the pressing plates are also provided with slots for the sliding of the hinge shaft at the end of the telescopic frame. The output end of the fourth electric push rod is connected to the pressing plates located on the left and right end faces. A plurality of crushing protrusions are equidistantly arranged on the side of the pressing plates.
[0020] By adopting the above technical solution, when the grapes fall to both sides of each pressing plate, the fourth electric push rod is controlled. With the extension and retraction of the telescopic rod, the two connected pressing plates are brought together smoothly. The grapes are pressed by the crushing protrusions, thus achieving the purpose of the first juice extraction of the grapes.
[0021] A further configuration of the present invention is as follows: the auxiliary pressing mechanism includes a pressing chamber fixed to the right side wall of the juicing chamber, two pressure rollers are horizontally arranged at the upper port of the pressing chamber, two meshing gears are provided at one end of the two pressure rollers, a third motor connected to one pressure roller is installed on the side of the pressing chamber away from the gears, and a juicing outlet is provided at the bottom left side of the pressing chamber, which leads into the juicing chamber, and a screen is provided inside the juicing outlet.
[0022] By adopting the above technical solution, when the grape skins and pulp after the first juicing enter the crushing chamber, the third motor controls the rotation of the pressure rollers. Under the meshing of two gears, the two pressure rollers rotate relative to each other, and the grape skins and pulp that have passed through are further crushed. The resulting juice falls into the juice collection chamber after being filtered through a screen, making the juicing effect of the device better.
[0023] A further feature of the present invention is that: a door is provided on the right side wall of the compaction chamber, a fixed seat is provided at the top right side of the door, a connecting block is fixedly connected to the right side wall of the compaction chamber above the fixed seat, a threaded rod is vertically provided at the center of the connecting block, a limiting block is provided at the lower end of the threaded rod and inserted into the fixed seat, and sliding rods are fixedly installed on both sides of the top of the limiting block and movably connected to the connecting block.
[0024] By adopting the above technical solution, after the grapes are squeezed dry, the staff can rotate the threaded rod, which, under the restriction of the sliding rod, causes the limiting block to move upward and disengage from the fixed seat, thus facilitating the opening of the silo door and allowing the internal residue to be cleaned smoothly.
[0025] The beneficial effects of this invention are: 1. This invention, through the setting of a seed removal mechanism, first pours a measured amount of washed grapes into the seed removal chamber before pressing. Then, the seed removal chamber is shaken left and right by a shaking mechanism, so that each grape is neatly placed into the grape placement rack. After the shaking stops, the first electric push rod is driven to push the pressure plate to move the seed removal pusher down, aligning it with the center of each grape and pushing out the grape seeds inside. The grape seeds pass through the grape placement rack and fall onto the seed removal plate. The seed removal plate is then pulled out to clean the grape seeds, thereby making the grape juice purer and the subsequent wine produced has a better taste.
[0026] 2. This invention, through the setting of a main pressing mechanism and a secondary pressing mechanism, controls the fourth electric push rod when the grapes fall to both sides of each pressing plate. Under the extension and retraction of the telescopic rod, the two connected pressing plates are brought together smoothly. The grapes are pressed by the crushing protrusions, achieving the purpose of the first juicing of the grapes. After the first juicing, the grape skins and pulp enter the crushing chamber through the scraping component. The third motor controls the rotation of the pressure rollers. Under the meshing of two gears, the two pressure rollers rotate relative to each other, and the grape skins and pulp that have passed through are further crushed. The resulting juice falls into the juice collection chamber after being filtered by the screen. This makes the juicing effect of the device better and the grape juice yield higher.
[0027] 3. After the grapes are squeezed dry, the operator can rotate the threaded rod, which, under the constraint of the sliding rod, causes the limiting block to move upward and disengage from the fixed seat, thereby facilitating the opening of the chamber door and allowing the internal residue to be cleaned smoothly. This makes the device more convenient to use and conducive to mass production. Attached Figure Description

[0036] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0037] like Figure 1 , Figure 2As shown, a grape crushing and pressing device for winemaking includes a pressing chamber 1. Below the pressing chamber 1, a deseeding plate 3, a main pressing mechanism 2, and a filter plate 4 are arranged sequentially. Below the filter plate 4, a pushing component 5 controls its lifting and lowering. A secondary pressing mechanism 6 is located on the right side of the pressing chamber 1. The inner cavity of the pressing chamber 1 also includes a scraping component 7 for pushing the grapes after the initial pressing on the filter plate 4 into the secondary pressing mechanism 6. A juice collection chamber 8 is located at the bottom of the inner cavity of the pressing chamber 1, and a deseeding mechanism 9 is located at the top for deseeding... Mechanism 9 includes two L-shaped main frames 91 fixedly connected to the top of the juicing chamber 1 and symmetrically arranged on both sides. A deseeding chamber 92 and a shaking mechanism 93 that pushes the deseeding chamber 92 to sway left and right are slidably arranged between the two L-shaped main frames 91. A grape placement rack 94 and a feeding assembly 95 are arranged inside the deseeding chamber 92. An L-shaped secondary frame 96 is fixedly connected to the rear end face of the top of the juicing chamber 1. Two first electric push rods 97 are fixedly installed on the top of the L-shaped secondary frame 96. A pressure plate 98 is installed between the output ends of the two first electric push rods 97. The bottom is equipped with multiple sets of deseeding needles 99. The worker first pours a measured amount of washed grapes into the deseeding chamber 92, then shakes the chamber 92 left and right using a shaking mechanism 93, causing each grape to fall neatly into the grape placement rack 94. After stopping the shaking, the first electric push rod 97 is driven, pushing the pressure plate 98 to move the deseeding needles 99 downwards, aligning them with the center of each grape and pushing out the seeds. The seeds pass through the grape placement rack 94 and fall onto the deseeding plate 3. The deseeding plate 3 is then pulled out, cleaning the grape seeds. The process is then completed by pushing... The component 5 controls the filter plate 4 to move upward and fit tightly against the main pressing mechanism 2. Then, the feeding component 95 pours the deseeded grapes onto the main pressing mechanism 2 for juicing. The grape juice is filtered through the filter plate 4 and falls into the juice collection chamber 8. The pushing component 5 then controls the filter plate 4 to move downward, so that the corresponding scraping component 7 sends the pressed grape skins and pulp into the secondary pressing mechanism 6 for secondary pressing, so that the grape seeds are extracted more thoroughly. This not only increases the yield of grape juice, but also improves the taste of the subsequent wine.
[0038] like Figure 2 As shown, the upper surface of the grape placement rack 94 is provided with multiple grape placement slots at equal intervals, and the lower surface of the grape placement slots is provided with a seed discharge port corresponding to the deseeding pusher 99. During the shaking of the grape placement rack 94, each grape is dropped into the corresponding grape placement slot. After the deseeding pusher 99 passes through the grape, the grape seeds are pushed out through the seed discharge port, causing the grape seeds to fall onto the deseeding plate 3 under gravity.
[0039] like Figure 2As shown, the shaking mechanism 93 includes a connecting plate 931 fixed to one side of the left L-shaped main frame 91. A first motor 932 is installed on the connecting plate 931. A cam 933 is installed at the output end of the first motor 932 to push the seed-removing bin 92 to the right. Two crossbars 934 are also provided between the two L-shaped main frames 91. Pushing blocks 935 that are slidably connected to the crossbars 934 are fixedly connected to the front and rear sides of the seed-removing bin 92. A connecting spring 936 is sleeved on the crossbar 934. The seed-removing bin 92 is located between the two crossbars 934. The two ends of the connecting spring 936 are respectively connected to the L-shaped main frame 91 and the pushing block 935. The first motor 932 controls the cam 933 to rotate. Since the pushing block 935 slides horizontally on the crossbar 934, it can intermittently push the seed-removing bin 92 to the right, while squeezing the connecting spring 936. With the extension and rebound of the connecting spring 936, the seed-removing bin 92 shakes left and right continuously, thereby arranging the grapes neatly on the grape placement rack 94.
[0040] like Figure 2 As shown, the feeding assembly 95 includes a second electric push rod 951 installed on the left side wall of the inner cavity of the deseeding chamber 92. The output end of the second electric push rod 951 is provided with a push-pull rod 952 that is hinged to the bottom of the grape placement rack 94. The left side of the grape placement rack 94 is hinged to the inner wall of the deseeding chamber 92. After the grapes have been deseeded, the second electric push rod 951 is driven, causing the push-pull rod 952 to control the grape placement rack 94 to rotate downward, thereby tilting the grapes to facilitate subsequent pressing.
[0041] like Figure 3 , Figure 4 As shown, the pushing component 5 includes a second motor 51 installed on the left side of the juicing chamber 1. A bidirectional lead screw 52 is installed at the output end of the second motor 51. A fixed rod 53 is provided below the bidirectional lead screw 52. Two sliding blocks 54 are threaded on the outer side of the bidirectional lead screw 52. The upper end of the sliding blocks 54 is hinged to an inclined rod 55 that is hinged to the bottom of the filter plate 4. The second motor 51 controls the bidirectional lead screw 52 to rotate. Under the restriction of the cross rod 53, the sliding blocks 54 on both sides are pushed to slide horizontally relative to each other. The inclined rod 55 pushes the filter plate 4 to rise, so that it contacts the bottom of the pressing plate 22. This allows the grapes to fall smoothly into the gap between each connected pressing plate 22 when they are poured, which is convenient for juicing.
[0042] like Figure 1 As shown, the deseeding plate 3 is detachably installed inside the juicing chamber 1, and a filter screen 31 is provided inside the deseeding plate 3. A handle 32 is fixedly connected to the right side of the deseeding plate 3. When the grape seeds fall onto the filter screen 31, the mixed grape juice drips down. The deseeding plate 3 can be pulled out as a whole through the handle 32 to easily clean the grape seeds.
[0043] like Figure 3As shown, the scraping component 7 includes two third electric push rods 71 installed on the left side wall of the juicing chamber 1. A push plate 72 is installed between the output ends of the two third electric push rods 71. A slag discharge port corresponding to the push plate 72 is provided on the right side wall of the juicing chamber 1. Driving the third electric push rods 71 controls the push plate 72 to move to the right, so that the grape skins and pulp after pressing enter the secondary pressing mechanism 6 for secondary pressing, which makes the device more automated and the juicing effect better.
[0044] like Figure 4 , Figure 5 As shown, the main pressing mechanism 2 includes a fourth electric push rod 21 installed on the left and right side walls of the juicing chamber 1 and multiple pressing plates 22 horizontally and equidistantly arranged in the inner cavity of the juicing chamber 1. Each pair of connected pressing plates 22 is hinged to a telescopic frame 23 on both the front and rear sides. The front and rear end faces of the pressing plates 22 are also provided with slots 24 for the sliding of the hinge shafts at the ends of the telescopic frames 23. The output end of the fourth electric push rod 21 is connected to the pressing plates 22 located on the left and right end faces. Multiple crushing protrusions 25 are equidistantly arranged on the sides of the pressing plates 22. When the grapes fall to both sides of each pressing plate 22, the fourth electric push rod 21 is controlled, and the telescopic rod 23 extends and retracts, so that each pair of connected pressing plates 22 are brought together smoothly. The grapes are pressed by the crushing protrusions 25, thus achieving the purpose of the first juicing of the grapes.
[0045] like Figure 6 , Figure 7 As shown, the secondary pressing mechanism 6 includes a pressing chamber 61 fixed to the right side wall of the juicing chamber 1. Two pressure rollers 62 are horizontally arranged at the upper end of the pressing chamber 61. Two meshing gears 63 are provided at one end of the two pressure rollers 62. A third motor 611 connected to one pressure roller 62 is installed on the side of the pressing chamber 61 away from the gears 63. A juicing outlet leading into the juicing chamber 1 is provided at the bottom left side of the pressing chamber 61. A screen 64 is provided inside the juicing outlet. When the grape skins and pulp after the first pressing enter the pressing chamber 61, the third motor 611 controls the pressure rollers 62 to rotate. Under the meshing of the two gears 63, the two pressure rollers 62 rotate relative to each other, and the grape skins and pulp that have passed through are further crushed. The resulting juice is filtered through the screen 64 and then falls into the juice collection chamber 8, making the juicing effect of the device better.
[0046] like Figure 7As shown, a door 65 is provided on the right side wall of the crushing chamber 61. A fixed seat 66 is provided on the top right side of the door 65. A connecting block 67 located above the fixed seat 66 is fixedly connected to the right side wall of the crushing chamber 61. A threaded rod 68 is vertically provided at the center of the connecting block 67. A limiting block 69 inserted into the fixed seat 66 is provided at the lower end of the threaded rod 68. Sliding rods 610 are fixedly installed on both sides of the top of the limiting block 69, passing through the connecting block 67 and movably connected to it. After the grapes are squeezed dry, the worker rotates the threaded rod 68, and under the restriction of the sliding rod 610, the limiting block 69 moves upward and disengages from the fixed seat 66, thereby facilitating the opening of the door 65 and allowing the internal residue to be cleaned smoothly.
