Description

Technical Field

[0001] The invention relates to the technical field of energy-saving grinding, in particular to a glutinous rice grinding device in a selenium-enriched wine production process. Background Art

[0002] Selenium-enriched wine is a nutritious wine produced through a specific process, which is characterized by being rich in selenium. Selenium is one of the essential trace elements for the human body and has many health benefits such as anti-oxidation and immunity enhancement. The production of selenium-enriched wine aims to integrate selenium into the wine through scientific methods to meet consumers' demand for healthy drinking. When producing selenium-enriched wine, the raw materials need to be ground, which helps to increase the contact area between the raw materials and the fermentation bacteria and improve the fermentation efficiency.

[0003] At present, there are two ways to convey glutinous rice to the grinding device for grinding. The first is to directly and continuously feed the soaked glutinous rice into the grinding and crushing device through a conveyor line. This method reduces the intermediate storage link and makes the production process more concise. However, this method has a large load on the grinding device, and during maintenance, the entire line needs to be shut down. The second is to first convey the soaked glutinous rice to the intermediate storage box through a conveyor line, and then feed the glutinous rice in the storage box into the grinding device. This method plays a buffering role, so that the grinding device will not be overloaded due to the continuous feeding of glutinous rice. High pressure is beneficial to protect the equipment and prolong its service life. When it is necessary to adjust the production rhythm or perform equipment maintenance, it can be achieved by adjusting the discharge speed of the intermediate storage box or pausing the discharge, which increases the flexibility of the production process. However, this method often requires a telescopic device or a reciprocating motion device to achieve repeated feeding of glutinous rice in the storage box. In this way, the reciprocating motion device or the telescopic device needs to move repeatedly intermittently for a period of time or for a long period of time, and the equipment ages quickly. In addition, multiple motor equipment is added, the cost is large, and energy consumption is increased, which is not conducive to energy conservation and emission reduction. Summary of the invention

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] See also Figure 1-13 , the embodiment of the present invention provides a technical solution: a glutinous rice grinding device in a selenium-enriched wine production process, comprising a frame 1 and a driving motor 2 and a hammer grinding device 3 installed on the frame 1, and a feed port 4 is arranged on the top of the hammer grinding device 3, the glutinous rice to be ground is input into the hammer grinding device 3 through the feed port 4, the driving motor 2 is started, and the hammer in the hammer grinding device 3 is driven to grind the glutinous rice, so that the ground glutinous rice particles can be used for the subsequent production of selenium-enriched wine, and a storage box 8 is also arranged on the frame 1, and the glutinous rice delivered can be intermediately stored through the storage box 8, instead of directly delivering the glutinous rice to the hammer grinding device 3, so as to reduce the pressure of the hammer grinding device 3, and secondly, when it is necessary to adjust the grinding rhythm or perform equipment maintenance, it can be achieved by adjusting the discharge speed of the intermediate storage box or suspending the discharge, without the need to shut down the entire conveying production line, thereby increasing the flexibility of the production process;

[0041] After the glutinous rice to be ground is conveyed into the storage box 8, the glutinous rice in the storage box 8 is intermittently fed into the hammer grinding device 3 through the feeding port 4 of the storage box 8 for grinding through the reciprocating feeding assembly 6 arranged between the driving motor 2 and the discharge port at the bottom of the storage box 8, so that the feeding is associated with the start and stop of the hammer grinding device 3 to form a correlated whole. When the hammer grinding device 3 needs to be temporarily stopped, there is no need to close the entire conveying line, but the glutinous rice can be temporarily stored through the storage box 8, thereby increasing the flexibility of overall use;

[0042] In one embodiment of the present invention, the reciprocating feeding assembly 6 includes a driving mechanism 61, which is arranged on a mounting plate 7 fixed to a material storage box 8. The driving motor 2 is provided with a reciprocating mechanism and a material discharging mechanism through the driving mechanism 61. When the driving motor 2 is started and rotates unidirectionally, the driving mechanism 61 drives the reciprocating mechanism to make the material discharging mechanism perform bidirectional reciprocating motion, thereby realizing the intermittent feeding of glutinous rice in the material storage box 8. In this way, under the unidirectional drive of the driving motor 2 that drives the hammer piece of the hammer grinding device 3 to rotate, the reciprocating mechanism and the material discharging mechanism can reciprocate, and the reciprocating motion can be realized without the need to set up a telescopic mechanism separately. Only a single motor is provided to realize the overall function, thereby saving resource utilization, improving the utilization rate of the load of the driving motor 2, and having a certain energy-saving effect compared with the use of multiple motor equipment.

[0043] In another embodiment of the present invention, the driving mechanism 61 includes a swivel 630 and a gear 1 63 rotatably arranged on the mounting plate 7, and the swivel 630 and the gear 1 63 are connected by a connecting piece, and the swivel 630 and the power output shaft of the driving motor 2 are installed with a synchronous belt 1 62 through a pulley. After the driving motor 2 is started, the swivel 630 rotates the gear 1 63 through the connecting piece through the synchronous belt 1 62. The driving mechanism 61 also includes two gears 2 64 rotatably arranged on the mounting plate 7 and meshing with each other, one of the gears 2 64 meshes with the gear 1 63, and screw rods 65 are fixedly installed on the rotation axes of the two gears 2 64, so that the rotation directions of the two gears 2 64 can be opposite through the gear 1 63, thereby making the rotation directions of the two screw rods 65 opposite;

[0044] A slide rail 68 slidably connected to the mounting slider 618 is installed on the mounting plate 7, and the reciprocating motion mechanism is arranged on the mounting slider 618, and the reciprocating motion mechanism includes a combined movable block 620 rotatably arranged on the mounting slider 618, and the two surfaces of the combined movable block 620 close to the two screw rods 65 are provided with threads adapted to the screw rods 65, and the combined movable block 620 will only be threadedly connected with one of the screw rods 65 at a time. When the screw rod 65 rotates, the combined movable block 620 drives the mounting slider 618 to move in one direction through the threaded structure with the screw rod 65, and after the movement is in place, the reciprocating motion mechanism drives the combined movable block 620 to rotate until it is threadedly connected with the other screw rod 65, and the rotation direction of the other screw rod is opposite, thereby realizing the reverse movement of the mounting slider 618;

[0045] It should be noted here that the detailed structure of the reciprocating mechanism that enables the combined movable block 620 to deflect to another screw rod 65 includes an adjusting rotating rod 625 and an adjusting card plate 621 that are rotatably arranged on the mounting slider 618, and two groups of push rods 67 that are symmetrically arranged and corresponding to each other. Each group of push rods 67 is fixedly arranged at the ends of the mounting plate 7 that are away from each other. When the combined movable block 620 is threadedly connected to one of the screw rods 65 and drives the mounting slider 618 to move in one direction, the push rod 67 will contact the adjusting rotating rod 625 and push the adjusting rotating rod 625 to rotate until the adjusting rotating rod 625 rotates to the other side. In one direction, the adjusting card plate 621 is clamped on the outer peripheral side surface of the raised part at the top of the combined movable block 620. At this time, the combined movable block 620 is rotated by adjusting the card plate 621, so that the combined movable block 620 is deflected toward another screw rod 65 and is threadedly connected to the screw rod 65. At this time, the combined movable block 620 drives the installation slider 618 to move in the opposite direction, and the two push rods 67 make the adjusting rotating rod 625 and the adjusting card plate 621 drive the combined movable block 620 to rotate periodically clockwise / counterclockwise, so that the combined movable block 620 is periodically threadedly connected with the two screw rods 65 to achieve reciprocating motion;

[0046] In order to prevent the combined movable block 620 from loosening when it is fitted with the screw rod 65, thereby preventing the installation slide block 618 from being unable to move, a telescopic frame 626 that slides in the through slot 623 is provided on the adjusting rotating rod 625 through an elastic member 2 627, and two limiting rods 624 are fixedly installed on the telescopic frame 626. Two limiting grooves 622 that are compatible with the limiting rods 624 are provided on both sides of the through slot 623 of the installation slide block 618. When the combined movable block 620 is threadedly engaged with one of the screw rods 65, the limiting rod 624 is inserted into one of the limiting grooves 622 to lock the angle of the adjusting rotating rod 625 to prevent the combined movable block 620 from being unstable in engagement with the screw rod 65. When the installation slide block 618 needs to turn, the reciprocating motion mechanism also includes two fixed devices, each of which is provided with a plurality of stoppers. The trapezoidal abutment block 66 is arranged on the surface of the mounting plate 7 which is away from each other, the through groove 623 is provided on the surface of the mounting slide block 618, and the cavity formed integrally with the through groove 623 on the mounting slide block 618, and a pressure ball 629 is slidably arranged on the inner wall surface of the cavity of the mounting slide block 618 through a bracket. After the mounting slide block 618 moves to insert the trapezoidal abutment block 66 into the cavity, the inclined surface of the trapezoidal abutment block 66 abuts against the pressure ball 629, so that the pressure ball 629 moves upward and partially emerges from the through groove 623, so that the telescopic frame 626 compresses the second elastic member 627 away from the through groove 623, thereby pushing the limit rod 624 out of the through groove 623, and at this time, the unlocking of the angle of the adjusting rotating rod 625 is realized, wherein the second elastic member 627 is a spring 616 column, which is a prior art and will not be described in detail here.

[0047] It should be noted that the action of pushing the pressure ball 629 upward by the trapezoidal abutment block 66 is before the adjusting rotating rod 625 contacts the push rod 67. After the angle of the adjusting rotating rod 625 is unlocked by the trapezoidal abutment block 66, the push rod 67 contacts the adjusting rotating rod 625, so that the angle between the adjusting rotating rod 625 and the adjusting clamping plate 621 is changed.

[0048] It should also be noted that the through slot 623 is configured as a whole so that the positions near the pressure balls 629 on both sides are connected to the cavity, while the other positions are not penetrated. In this way, after the pressure balls 629 are pushed upward by the telescopic frame 626 and the adjusting rotating rod 625 is rotated by the push rod 67, the telescopic frame 626 can abut against the bottom surface of the through slot 623 instead of extending into the cavity. In this way, the height of the limiting rod 624 is higher than the surface of the mounting slide 618. Then, after the telescopic frame 626 moves to the position of the through slot 623 penetrating the cavity, the telescopic frame 626 is pressed downward, thereby driving the limiting rod 624 to be clamped into the limiting slot 622.

[0049] It should also be noted that in order to prevent the combined movable block 620 from stopping moving during the process of separating from one screw rod 65 and threadedly engaging with the other screw rod 65 when the combined movable block 620 is turning, the spacing between the two screw rods 65 should not be set too large, and the setting of the gap should ensure that: when the combined movable block 620 is not in contact with the two screw rods 65, the installation slider 618 can still push the push rod 67 to push the adjustment rotating rod 625 to the other side under the inertia of movement, and insert the limit rod 624 into the limit groove 622 on the other side, so that the combined movable block 620 can fit on the other screw rod 65 to form a threaded engagement;

[0050] In order to further prevent the combined movable block 620 from stopping moving during the process of separating from one screw rod 65 and threadedly engaging with another screw rod 65 when the combined movable block 620 is turning, the present invention also provides another embodiment, see Fig.13 , an elastic member 631 is installed between the mounting slider 618 and the adjusting rotating rod 625, and the length of the elastic member 631 is greater than the distance from the adjusting rotating rod 625 to the center of its rotation circle. When the adjusting rotating rod 625 is in the locked state, the elastic member 631 is in the initial state. When the push rod 67 pushes the adjusting rotating rod 625 to rotate, the end of the elastic member 631 away from the connection with the adjusting rotating rod 625 is in an eccentric position, and the elastic member 631 is gradually stretched until the adjusting rotating rod 625 rotates more than half of the total path. At this time, due to the elastic member 631 being If the force is uneven and the deformation is restored, the elastic potential energy will accelerate the adjustment lever 625 to rotate to the other side, so that the limit rod 624 can be quickly inserted into the limit groove 622 on the other side. The elastic force of the elastic member 631 can make the combined movable block 620 separate from the two screw rods 65, pull the combined movable block 620 to be threadedly engaged with the other screw rod 65. The dual protection of inertia and the elastic member 631 further guarantees the overall use effect. The elastic member can be an elastic drawstring or a spring 616 column, which are all existing technologies and will not be repeated.

[0051] When the combined movable block 620 is separated from one of the screw rods 65 and is threadedly engaged with the other screw rod 65, in order to reduce the wear caused by the separation and fit of the threads opened on the combined movable block 620 when the screw rod 65 rotates, the glutinous rice grinding device in the selenium-enriched wine production process also includes a buffer mechanism 5 connecting the connecting piece with the mounting slider 618. When the combined movable block 620 turns and is threadedly engaged with the other screw rod 65, the buffer mechanism 5 is used to make the connecting piece temporarily separate / combine, so as to realize the deceleration / recovery action of the two screw rods 65 and reduce wear;

[0052] In another embodiment of the present invention, the connecting member includes a shaft 1 6101 fixedly connected to the gear 1 63, a shaft 2 6105 fixedly connected to the swivel 630, two sets of slide grooves 6103 are opened on the shaft 1 6101, and passive rotating blocks 6102 are slidably arranged in the two sets of slide grooves 6103, and a push block 6104 is fixedly arranged on the shaft 2 6105. When the shaft 2 6105 rotates, the push block 6104 intermittently abuts against the surfaces of the two push blocks 6104 to realize the rotation of the shaft 1 6101; wherein the buffer mechanism 5 includes a forward and reverse screw 55 rotatably arranged on one side mounting plate 7, a gear 3 51 installed at the end of the forward and reverse screw 55, and a gear 52 rotatably arranged on the other side. Gear four 56 on the side mounting plate 7, two limiting clamps 58 are threadedly mounted on the forward and reverse lead screw 55, and the surfaces of the two limiting clamps 58 close to each other are arranged in a circular array with multiple rollers, the rotating shafts of the gear three 51 and the gear four 56 are installed with a synchronous belt two 57 through a pulley, and a Z-shaped frame 53 is also fixedly arranged on the mounting slider 618, and the Z-shaped frame 53 is provided with a meshing tooth two 52 and a meshing tooth three 54, when the mounting slider 618 reciprocates, the meshing tooth two 52 and the meshing tooth three 54 are meshed with the gear three 51 and the gear four 56 respectively, and a passive rotating block 6102 is threadedly mounted on the forward and reverse lead screw 55, and the passive rotating block 6102 is used to make the connecting member rotate synchronously;

[0053] When the adjusting rotating rod 625 is about to contact with the pushing rod 67, the meshing teeth 2 52 and the meshing teeth 3 54 provided on the Z-shaped frame 53 on the mounting slide block 618 contact with the gear 3 51 and the gear 4 56 respectively. When the meshing teeth 2 52 are meshed with the gear 3 51, the forward and reverse screws 55 rotate. When the meshing teeth 3 54 are in contact with the gear 4 56, the forward and reverse screws 55 are also rotated through the synchronous belt 2 57. When the forward and reverse screws 55 rotate, the two limiting clamps 58 move away from each other. At this time, the pushing block 6104 on the second shaft 6105 pushes the passive rotating block 6102 to rotate the first shaft 6101, thereby driving the two gears 2 64 to rotate through the gear 1 63, and the passive rotating block 6102 on the first shaft 6101 that resists the pushing block 6104 When the movable block 6102 rotates to below the horizontal direction of the axis of the shaft 1 6101, the passive rotating block 6102 will slide to the bottom of the slide groove 6103 under the action of gravity and separate from the push block 6104. At this time, the shaft 1 6101 cannot rotate actively, but rotates under the action of inertia, and there is no external force to push it. The shaft 1 6101 gradually slows down, thereby driving the two screw rods 65 to gradually slow down through the gear 1 63 and the two gears 2 64. In this way, when the wire on the combined movable block 620 separates from one of the screw rods 65 and fits on the surface of the other screw rod 65, the friction is reduced, so that the two screw rods 65 and the wire on the surface of the combined movable block 620 are separated and fitted at a slower speed, thereby improving the overall service life.

[0054] Please note that Fig.12In order to prevent the friction force of the push block 6104 on the rear surface of the passive rotating block 6102 from causing the passive rotating block 6102 to fall and separate from the push block 6104, a rotating wheel can be provided on the surface of the passive rotating block 6102 to reduce friction, so that the passive rotating block 6102 can be automatically separated from the push block 6104 after rotating with the shaft 1 6101 to a lower angle, and the two ends of the passive rotating block 6102 are larger than the slide groove 6103 and will not fall from the slide groove 6103;

[0055] In another embodiment of the present invention, the material discharging mechanism includes a combined bracket 69 fixedly mounted on a mounting slide 618 and one end of which extends to the bottom of the material storage box 8, and a material discharging barrel 610 rotatably mounted on the combined bracket 69. The material discharging barrel 610 can receive the glutinous rice discharged from the material storage box 8. A toothed bar 612 is disposed on the outer peripheral side of the material discharging barrel 610, and a rack 615 is fixedly disposed on the outer surface of the feed port 4. Then, when the material discharging barrel 610 reciprocates under the drive of the combined bracket 69 and approaches the feed port 4, the toothed bar 612 engages with the rack 615 to flip the material discharging barrel 610 to realize the action of pouring the glutinous rice into the feed port 4.

[0056] In order to allow the glutinous rice in the material storage box 8 to be dumped after the material storage barrel 610 is in place and closed after the material storage barrel 610 leaves, the material discharging mechanism also includes a closing plate 614 slidably arranged at the material storage box 8 discharge port position, and the closing plate 614 is connected to the material storage box 8 through multiple sets of springs 616, and a lever 611 is slidably inserted on the material storage box 8. When the combined bracket 69 and the lever 611 are against each other and continue to move toward the direction close to the feed port 4, the closing plate 614 is pushed to open, and the glutinous rice is discharged from the material storage box 8. The material outlet is poured out and enters the material storage barrel 610. After the closing plate 614 is opened to the limit position, a hole 613 is further provided on the material storage box 8, and the position where the lever 611 contacts the combined bracket 69 is set to an arc shape, so that the lever 611 can be pushed into the hole 613 through the combined bracket 69. At this time, the combined bracket 69 is separated from the lever 611, and the lever 611 falls back under the action of gravity, and the spring 616 recovers its deformation, so that the closing plate 614 rebounds quickly to close the material outlet of the material storage box 8.

[0057] When the combined bracket 69 drives the material holding barrel 610 to return, the combined bracket 69 pushes the lever 611 to make the closing plate 614 drive the spring 616 to stretch and deform. Since the holes 613 opened on the material storage box 8 are distributed in a rectangular array, please refer to Figure 5After the closing plate 614 moves a short distance, the lever 611 will be pushed into the hole 613. The size of the closing plate 614 is larger than the size of the discharge port of the discharge box. The movement distance of the closing plate 614 cannot open the discharge port, and the glutinous rice will not fall out. In this way, reciprocating feeding is realized. The entire reciprocating feeding can be realized by a single drive motor 2, and there is no need to set up multiple motor equipment, which saves costs. Even if multiple loads are driven by a single motor, the overall energy consumption is lower than that of multiple motors working together, which has a certain energy-saving effect.

[0058] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
