Description

Technical Field

[0001] The invention relates to the technical field of sauce wine production equipment, and in particular to a drying machine. Background Art

[0002] In the brewing process of Maotai-flavor liquor, airing is a very critical process. Traditional Maotai liquor brewing must follow the 12987 process, which requires 9 steamings. In addition to the last round of discarding the dregs, it needs to go through 8 airing processes. Each time it is aired, the steamed grain or fermented grains need to be poured directly onto the floor of the airing hall with a wine retort, and a large number of people are used to evenly sprinkle the hot high-temperature materials on the floor of the airing hall with a shovel in a short time. Then, the processes of stemming, spreading tail wine, spreading koji, and collecting materials need to be completed in succession. The entire production process is labor-intensive and the working environment is poor. Workers need to overcome the effects of high temperature, physical strength, dust, etc. At the same time, the degree of standardization of the entire airing operation is affected by the personal status of the producer. For example, the control of stemming, spreading tail wine, spreading koji, and mixing koji uniformity, and the control of koji temperature will directly affect the amount and quality of the next round of wine production.

[0003] The mechanized air-drying machine of the prior art usually uses a chain plate as a carrier for air-drying instead of an air-drying hall. This method is relatively mature in the brewing process of other types of liquor. However, this method is not suitable for the brewing of Maotai-flavor liquor. The brewing of Maotai-flavor liquor needs to follow the principle of being down-to-earth. The traditional method is to air-dry on the Sanhe soil ground, which is conducive to the growth of beneficial microbial flora. Only by using the method of ground airing and utilizing the role of microorganisms can the most fundamental flavor and taste of Maotai-flavor liquor be guaranteed. An automated air-drying machine that can simulate the traditional production process, be down-to-earth, greatly reduce the labor intensity of workers, improve the working environment, and stabilize the output and quality of Maotai-flavor liquor has become the future production development direction of major Maotai-flavor liquor companies.

DETAILED DESCRIPTION

[0032] The embodiment of the present invention provides a drying machine, such as Figure 1-9As shown, it includes a crane 1, a material holding mechanism 2, a koji adding mechanism 8, a multi-station lifting mechanism, a multi-station component, a cooling fan 5, a tail wine spreading device 9, a shovel machine 6, and a material receiving trough 7.

[0033] like Figure 1-2 As shown, the crane 1 includes a transverse traveling frame 11, a transverse traveling assembly 12, and a longitudinal moving track 13. The bending mechanism 8 is arranged on the material holding mechanism 2 and can move longitudinally with the material holding mechanism 2. The multi-station assembly includes a stemming mechanism 3 and a mixing mechanism 4. The stemming mechanism 3 and the mixing mechanism 4 are connected to the lower part of the material holding mechanism 2 through a multi-station lifting mechanism. The transverse traveling assembly 12 is arranged on the transverse traveling frame 11 and is used to drive the transverse traveling frame 11 to move transversely. The transverse traveling assembly 12 is an existing mature technology, which mainly includes a reduction motor, a driving wheel and a traveling wheel meshed therewith. The traveling wheel is arranged at the bottom of the transverse traveling frame 11 and is used to walk on the ground. The driving wheel is driven by the reduction motor, and then the driving wheel drives the traveling wheel to rotate. The longitudinal moving track 13 is arranged on the transverse traveling frame 11, and the longitudinal traveling assembly 14 is arranged on the material holding mechanism 2 and is used to drive the material holding mechanism 2 to move longitudinally. The structure of the longitudinal traveling assembly 14 is consistent with that of the transverse traveling assembly 12.

[0034] like Figure 3 As shown, the multi-station lifting mechanism is arranged on the material holding mechanism 2 and is used to drive the lifting frame 15 to lift; the multi-station lifting mechanism is connected to the lower part of the material holding hopper conveyor. The existing screw lifting unit is used for lifting, and the driving method is that the motor is decelerated and then drives the spiral bevel gear steering box, and the output of the spiral bevel gear steering box drives 4 screw lifts for lifting.

[0035] like Figure 5 As shown, the material holding mechanism 2 includes a trough body 21, the bottom of the trough body 21 and a side connected thereto are both open, a main conveyor belt 22 is arranged at the bottom of the trough body 21 along the length direction of the trough body 21, a material distribution conveyor belt 23 is vertically arranged on the open side of the trough body 21, and a material discharge port 28 is formed between the main conveyor belt 22 and the material distribution conveyor belt 23. Both the main conveyor belt 22 and the material distribution conveyor belt 23 are existing mature prior art, and can be a chain conveyor belt, mainly including a driving motor, two front and rear driving rollers, and a conveyor belt meshed outside the rollers.

[0036] The material dividing conveyor belt 23 is provided with material dividing rods 25 at intervals. The material dividing rods 25 are arranged in a plurality of rows along the length direction of the conveyor belt, and the material dividing rods 25 in two adjacent rows are arranged alternately front and back. The length of the material dividing rods 25 is slightly smaller than the height of the material outlet 28 to prevent the material dividing rods 25 from touching the main conveyor belt 22.

[0037] The lees in the trough body 21 are driven by the main conveyor belt 22 toward the discharge port 28. At the discharge port 28, the dividing conveyor belt 23 limits the discharge thickness of the lees, and the dividing rod 25 evenly breaks up the clumping lees, so that the lees are discharged evenly and are not easy to form lumps. At the same time, due to the continuous circumferential motion of the dividing conveyor belt, the lees at the discharge port 28 can be stirred to prevent the lees from being blocked at the discharge port 28.

[0038] In order to prevent the lees from accumulating on the side walls of the trough body 21, the bottom of the trough body 21 is in the shape of an inclined funnel. The two inclined plates on both sides of the bottom of the trough body 21 are movable pushing plates 26. One end of the pushing plate 26 is hinged to the trough body 21. The trough body 21 is provided with a driving component 27 for driving the pushing plate 26 to flip.

[0039] The drive assembly 27 may be a screw-lift type worm gear screw lift.

[0040] like Figure 5 As shown, the driving assembly 27 includes a base 271, a worm gear transmission component 272, a screw 273, and a motor 274. The base 271 is rotatably connected to the tank body 21 through a bearing seat, the worm gear transmission component 272 is arranged on the base 271, and the motor 274 is arranged on the base 271 and is coaxially connected to the worm of the worm gear transmission component 272. A screw hole matching the screw 273 thread is arranged at the center of the worm wheel of the worm gear transmission component 272, and one end of the screw 273 is hinged on the push plate 26. The motor 274 is used to drive the worm to rotate, the worm drives the worm wheel to rotate, and then the worm wheel drives the screw 273 at the center to rise and fall, so as to realize the flipping drive of the push plate 26.

[0041] When the amount of lees discharged from the center of the trough body 21 gradually decreases, the two push plates 26 on both sides are turned over toward the opening direction, so that the lees on both sides of the trough body 21 slide toward the central opening, and the discharge is more complete.

[0042] like Figure 7 As shown, the stem lifting mechanism 3 includes a plurality of shovel plates 32, a stem lifting swing shaft 33, and a driving assembly. Both ends of the stem lifting swing shaft 33 are rotatably arranged on the lifting frame 15 through bearing seats.

[0043] A plurality of shovel plates 32 are arranged at intervals along the length direction of the stem lifting swing shaft 33, and the shovel plates 32 are connected to the stem lifting swing shaft 33 through a stem lifting swing arm 34. Specifically, the top end of the stem lifting swing arm 34 is fixed on the stem lifting swing shaft 33, and the bottom end is damping-hinged with the shovel plates 32. Under normal conditions, the shovel plates 32 and the stem lifting swing arm 34 are L-shaped. In order to improve the stem lifting effect, the shovel handles of the plurality of shovel plates 32 are arranged alternately in long and short lengths.

[0044] The shovel plate 32 is in an arc shape, and the arc convex surface faces away from the ground. The shoveled wine lees will slide down along the arc on the shovel plate 32 to avoid being accumulated on the shovel plate 32.

[0045] The driving assembly is used to drive the stemming swing shaft 33 to swing back and forth. If the swing amplitude is too large, the lees will easily fly up. The driving assembly drives the stemming swing shaft 33 to swing by 60-90 degrees, so that the shovel plate 32 can achieve the best effect of simulating artificial stemming.

[0046] Two groups of stemming mechanisms are provided, and the shovel plates 32 of the two groups of stemming mechanisms are oriented in opposite directions as well as the driving directions of the driving components, so that the airing machine can perform stemming operation on the wine lees when moving forward or backward, thereby improving the operation efficiency.

[0047] like Figure 7 As shown, the driving assembly includes a reducer 35, a crank 36, a connecting rod 37, and a driving swing arm 38. The reducer 35 is arranged on the lifting frame 15. The reducer 35 is a prior art, and the model may be a NMRV030-090 worm gear reducer. One end of the driving swing arm 38 is fixed to the stem lifting swing shaft 33, one end of the crank 36 is fixed to the output shaft of the reducer 35, and the other end is hinged to the driving swing arm 38 through the connecting rod 37. The crank 36 is driven to rotate by the reducer 35, and the crank 36 drives the driving swing arm 38 to swing back and forth through the connecting rod 37, thereby realizing a movement of the shovel plate 32 moving forward parallelly and slightly upward, which highly simulates the action of artificial stem lifting. Compared with the rotary stem lifting method, it can shovel the lees attached to the ground, and the stem lifting effect is better.

[0048] like Figure 7 As shown, when the shovel board 32 is not in use, in order to prevent it from contacting the ground, it also includes a lifting assembly for raising the height of the shovel board 32. The lifting assembly includes a lifting rod 39, a lifting arm, a cylinder and a hinged rod. The lifting rod 39 is arranged at the bottom end of the lifting arm and is located at the bottom of the shovel handles of several shovel boards 32. The top end of the lifting arm is mounted on the stem lifting swing shaft 33 through a bearing sleeve. The stem lifting swing shaft 33 does not affect the lifting arm when it rotates. The base of the cylinder is hinged on the lifting frame 15, one end of the hinged rod is fixed on the bearing sleeve of the lifting arm, and the other end is hinged to the output end of the cylinder. When the shovel board 32 needs to be lifted, the lifting arm is driven by the cylinder to move upward. Figure 7 The lifting arm drives the lifting rod 39 in the clockwise direction, and the lifting arm drives the lifting rod 39 to move upward, thereby linking the plurality of shovel plates 32 to rise and leave the ground.

[0049] like Figure 8As shown, the kneading mechanism 4 includes a crossbar 42 and a driving mechanism. The crossbar 42 is transversely arranged on the lifting frame 15. A plurality of kneading components are arranged on the crossbar 42 at equal intervals along its length direction. The driving mechanism is used to link the rotation of the plurality of kneading components. The kneading components include a kneading disk 43 and a plurality of kneaders. The kneading disk 43 is rotatably arranged at the bottom of the crossbar 42 through a bearing seat. A plurality of kneaders are arranged at the bottom of the kneading disk 3 and are distributed at equal angles around the center. The kneader includes a fixed seat 45, a plastic pipe 46, a joint 47, and a kneading rod 44 connected in sequence from top to bottom. Specifically, the fixed seat 45 and the joint 47 are both sleeves, and the upper and lower ends of the plastic pipe 46 extend into the fixed seat 45 and the joint 47 and are fixed with bolts. The plastic pipe 46 is made of polyurethane. When the mixing rod 44 rotates and contacts the ground, the plastic pipe 46 has a certain flexibility, expansion or bending function, which reduces the rigid contact between the mixing rod 44 and the ground, prevents the mixing rod 44 from breaking, and prolongs the service life of the mixing rod 44.

[0050] The kneading rods 44 are inclined outward, and the kneading rods 44 of two adjacent kneading assemblies are cross-engaged. The cross-designed kneading rods 44 can avoid kneading gaps and make the lees kneading more uniform.

[0051] like Fig. 9 As shown, the driving mechanism includes a transmission shaft 48, a driving reducer 49, and a plurality of driving gears 410 and driven gears 411, the same number as the number of the mixing components. The two ends of the transmission shaft 48 are arranged in the crossbar 42 through the bearing seat 413. A driven gear 411 is coaxially arranged on the rotating shaft of each mixing disk 43. A plurality of driving gears 410 are coaxially sleeved on the transmission shaft 48 and mesh with the driven gears 411 one by one. The driving gears 410 and the driven gears 411 are both bevel gears. The driving reducer 49 is arranged on the bearing seat 413 and is connected to the transmission shaft 48. The driving reducer 49 drives the transmission shaft 48 to rotate, and the driving gear 410 on the transmission shaft 48 drives the driven gear 411 to rotate, thereby driving the plurality of mixing disks 43 to rotate.

[0052] Due to different application scenarios and the wear of the mixing rod 44, the device also includes a lifting mechanism for raising the height of the cross bar 42.

[0053] like Figure 2As shown, the lifting mechanism includes a driving cylinder 414, a sleeve 415, a lifting arm 416 and a connecting rod 417. A slot that can be penetrated is provided on the lifting frame 15, and guide rails 412 are vertically arranged on both sides of the slot. Both sides of the bearing seat 413 are slidably adapted on the guide rails 412 through sliders. The sleeve 415 is sleeved outside the rotating shaft of the bearing seat 413, and the middle part of the lifting arm 416 is rotatably connected to the lifting frame 15. The base of the driving cylinder 414 is hinged on the lifting frame 15, and the output end is hinged to one end of the lifting arm 416, and the other end of the lifting arm 416 is hinged to the sleeve 415 through the connecting rod 417. The lifting arm 416 acts as a lever. When the driving cylinder 414 is driven, the bearing seat 413 is lifted and lowered through the lifting arm 416, thereby adjusting the height of the mixing rod 44 to achieve the best mixing position.

[0054] A guide conveyor belt 24 is provided at the junction of the discharge port 28 and the kneading mechanism 4, and the guide conveyor belt 24 is fixed on the lifting frame 15. The guide conveyor belt 24, like the main conveyor belt 22 and the material distribution conveyor belt 23, is a mature existing technology, and can be a chain conveyor belt. The front end of the guide conveyor belt 24 corresponds to the discharge port 28, and is used to guide the wine lees from the discharge port 28 to the front end of the kneading mechanism 4.

[0055] like Figure 4 As shown, the koji adding mechanism 8 includes a koji adding bucket 81 and a koji powder dropping buffer pipe 82 arranged at the bottom outlet of the koji adding bucket 81, the koji powder dropping buffer pipe 82 corresponds to the stem raising mechanism 3 up and down, and a discharging structure 83 is arranged at the outlet of the koji adding bucket 81. The koji powder discharging structure 83 adopts a servo motor to control the rotation speed of the koji adding roller at the lower part of the koji hopper. There are several equally divided grooves on the surface of the koji adding roller, and the koji adding roller is installed in the upper and lower open drums. When the koji powder enters the groove of the koji adding roller, the volumetric conveying effect with the inner wall of the drum during rotation makes the koji amount per revolution uniform, and the motor speed parameters are controlled to achieve quantitative koji adding in different rounds.

[0056] A plurality of cooling fans 5 are provided at the front end of the drying machine. The plurality of cooling fans are longitudinally arranged at the front end of the traveling crane 1 for cooling the wine lees.

[0057] After the lees are dried, the lees on the ground are shoveled into the receiving trough 7 by the shovel machine 6 .

[0058] like Figure 6As shown, the scraper 6 is fixed on the tank body 21 through a support column 61, and the scraper 6 includes a scraper bracket 62, a reduction motor 63, a plurality of sprockets 64, and an endless conveyor belt hingedly connected by a plurality of chain plates 65.

The reduction motor 63 is used to drive the sprocket 64, and the reduction motor 63 is an existing mature component.

[0059] Each chain plate 65 is provided with an arc-shaped toothed scraper 66, and the arc direction extends in an arc shape forward and upward in the conveying direction of the chain plate 65. When the toothed scraper 66 is on the back side of the downward moving conveyor belt, the end of the toothed scraper 66 is bent downward, and when the toothed scraper 66 is on the front side of the upward moving conveyor belt, the end of the toothed scraper 66 is bent upward.

[0060] The top rear side of the shovel bracket 62 is provided with a material guide plate for guiding the material conveyed by the toothed shovel blade 66 to the material receiving trough 7. When the toothed shovel blade 66 scoops up the material and conveys it to the top of the conveyor belt and turns it downward, the toothed shovel blade 66 turns the material onto the material guide plate, and the material slides into the material receiving trough 7 through the material guide plate.

[0061] A material discharging mechanism is provided at the front end of the bottom of the shoveling bracket 62. The function of the material discharging mechanism is similar to that of the material discharging device at the front end of the harvester. The material discharging mechanism includes a swing arm, a driving shaft, and a driving motor. One end of the swing arm is fixed on the shoveling bracket 62 and extends horizontally along the front end of the lowest toothed blade 66. The driving shaft is rotatably set at the top of the swing arm. The driving motor is set on the swing arm and is coaxially connected to the driving shaft. A number of material discharging blades 67 are arranged in an outer ring of the driving shaft.

[0062] A material collecting blade 68 for scooping up the mash is provided below the bottom toothed blade 66. The material collecting blade 68 is made of a plastic material, such as PVC.

[0063] The support column 61 is provided with a lifting mechanism for adjusting the height of the shovel bracket 62.

The plurality of rollers are arranged on the shovel bracket 62 and slideably fit in the fixed track. The lifting shaft of the screw screw jack is connected to the shovel bracket. The screw screw jack can be an SJA screw screw jack, which is an existing mature product. The distance between the toothed scraper 66 and the ground can be adjusted by the screw screw jack according to process requirements.

[0064] The lifting mechanism is used to lift the entire shovel machine. When the equipment is in the process of spreading and drying the stems, adding koji, and mixing the koji, the entire shovel conveying component is in an ascending state, with a lifting distance from the ground. When it is necessary to collect the material, it is lowered and the collecting shovel blade 68 is adjusted to contact the ground.

[0065] It also includes a follower platform 10 for supporting the material receiving trough 7. The follower platform 10 is connected to the transverse traveling frame 11 through a connector 101.
