Description

[Technical field]

[0001] The present invention relates to the field of food processing, and in particular to a grain dedusting device for food processing. [Background technology]

[0002] Food is generally categorized as grain, which contains rich nutrients, mainly proteins, vitamins, dietary fiber, fats, starch and so on. The surface of grains is usually covered with dust and chaff, so grains need to be dedusted and chaffed during primary processing, which can remove impurities from the grain surface and improve the quality of grains.

[0003] However, until now, the general method for removing dust and husks from grains has been to release the grains into the air and use the wind to blow away the dust and husks mixed with the grains, thereby separating the grains from the dust and husks. However, there are the following problems with adopting wind separation: First, the force of wind can only blow away the dust mixed with the grain, but cannot remove the dust that has adhered to the surface of the grain. As a result, the dust removal effect is poor; moreover, the wind separation method is prone to blowing dust and rice husks into the air, generating dust and affecting the environment. Second, because the chaff is usually wrapped around the outside of the grain, when the wind blows through the grain, the chaff is easily blown up along with the whole grain inside, making it difficult to effectively separate the grain from the chaff, resulting in wasted grain. Therefore, in light of the above, there is room for improvement in the conventional grain dust removal technical means. Summary of the Invention [Means for solving the problem]

[0015] In view of the above, the present application has at least one of the following beneficial technical effects: First, the present application forms a water curtain by spraying mist from the spray heads on both sides of the feed hopper, which makes it easier to wet the grain injected into the feed hopper, thereby preventing dust from scattering when the grain is injected into the feed hopper. In addition, by using a water washing method in combination with a partition net, the grain and rice husk can be separated, and the rice husk can be sieved out to avoid wasting the grain. Secondly, the present application uses a water washing method to wash the grain, and the grain is stirred and washed through the mutually rotating agitator tooth plate and positioning block, and the dust mixed in the grain can be effectively removed, thereby enhancing the dust removal effect on the grain. In addition, by sealing the loading / unloading port with a stop plate, the stirring and washing time of the grain by the agitator tooth plate can be extended, and the washing effect can be further improved. Third, in this application, due to the mutual cooperation between the fan plate and the protruding bar on the water filter plate, a gap appears between two adjacent fan plates, so that the water and some dust at the upper end of the water filter plate flow down through the gap and fall onto the filtering mesh plate, leaving only grains at the upper end of the water filter plate, so that the grains and water can be quickly separated. At this time, the water is discharged into the annular internal hollow pipe by the water pump, and sprayed out to the upper end of the water filter plate through the liquid discharge hole, facilitating the secondary washing of the grains, thereby completely removing the dust remaining on the grain surface, and easily enhancing the grain dust removal effect, and no dust scattering occurs during dust removal, avoiding any impact on the air environment. Fourth, in the present application, the conversion slide block can be controlled to make a corresponding movement according to the up and down movement of the water filter plate, and the conversion slide block can change the communication state between the first water outlet pipe, the second water outlet pipe and the pump output end, and further discharge water according to the grain washing process, which is simple to operate and does not require a separate drive. Fifth, by stirring the grain at the upper end of the water filtering plate, the present application can ensure that the water in the grain can flow out quickly through the gaps in the fan-shaped plate; at the same time, when the grain comes into contact with the hollow supporting rod, hollow rectangular plate and positioning rod after heating, the evaporation of moisture on the grain surface can be accelerated; and the hot air flow inside the hollow rectangular plate can be ejected through the exhaust holes, thereby increasing the heating area of ​​the grain and thus improving the drying efficiency of the grain.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIG. 1 to FIG. 14. However, the present invention can be embodied in various different forms as defined and covered by the claims.

[0018] The embodiments of the present application disclose and explain a grain dust removing apparatus for food processing. This grain dust removing apparatus for food processing is mainly applied to the process of removing dust from grains. In terms of technical effect, it solves the problems of dust scattering when grains are fed into the feeding hopper 331, and poor dust removing effect due to the inclusion of chaff and dust that tends to remain on the grain surface in the grains. In particular, when performing grain dust removing processing, the grains can be washed using a water washing method to effectively remove dust mixed in the grains, thereby improving the dust removing effect of the grains. Furthermore, this grain dust removing apparatus for food processing can quickly separate the grains from the water, and can perform a secondary washing of the grains, thereby completely removing the dust remaining on the grain surface, and further enhancing the dust removing effect on the grains. In addition, this grain dust removal device for food processing forms a water curtain using mist sprayed from the spray head, making it easier to moisten the grain injected into the feed hopper 331, thereby preventing dust from scattering when the grain is injected into the feed hopper 331. By using a water washing method in combination with a partition net, the grain and rice husk can be separated, and the rice husk can be sieved out to avoid wasting the grain.

[0019] Example 1 As shown in Figures 1 and 2, this is a grain dust removal device for food processing, and includes a processing tube 1, an inlet 11 is provided at the upper end of the processing tube 1, and a support and discharge unit 2 is attached to the lower end of the processing tube 1. The support and discharge unit 2 includes a support stand 21 located below the processing tube 1. Inside the processing tube 1, a cleaning unit 3 and a filtration unit 5 are arranged in order from top to bottom, and the filtration unit 5 includes a water filter plate 51 attached to the center of the inner wall of the processing tube 1.

[0020] In a specific implementation, grain is fed into the processing tube 1 through the input port 11, during which the washing unit 3 sprays water onto the grain above the input port 11 to prevent dust from scattering due to friction between the grains and remove chaff mixed in with the grains. After that, the washing unit 3 washes the grains inside the processing tube 1 to remove the dust on the grains' surfaces, and the filtering unit 5 filters the washed dust and dries the washed grains. Finally, the washed grains are discharged through the supporting and discharging unit 2.

[0021] As shown in Figures 2, 3 and 4, in order to completely remove dust mixed in the grain, in this embodiment, the grain is washed using a water washing method. Specifically, the washing unit 3 includes an annular plate 31, the annular plate 31 is attached to the upper part of the inner wall of the processing tube 1, the inner wall of the annular plate 31 is provided with a tapered plate 32, the processing tube 1 is equipped with an actuator 33, the actuator 33 includes a feed hopper 331 provided at the upper end center of the processing tube 1, the inner wall of the processing tube 1 is rotatably connected to an annular ring gear 36, the inner wall of the annular ring gear 36 is uniformly provided with a plurality of stirring tooth plates 37 distributed in a ring shape, the upper end of the annular plate 31 is equipped with a plurality of positioning blocks 38 arranged alternately with the stirring tooth plates 37, and a loading / unloading mechanism 39 is provided between the annular plate 31 and the tapered plate 32.

[0022] Continuing to refer to FIG. 2, in order to facilitate the automatic cleaning process of the grain, in this embodiment, a positioning motor 361 is attached to the outer wall of the processing tube 1 via a motor holder, a support shaft 362 is attached to the output shaft of the positioning motor 361, a first gear 363 and a second gear 364 are symmetrically provided on the outer wall of the support shaft 362, and the first gear 363 and the annular ring gear 36 are meshed with each other.

[0023] In the specific implementation process, after the grain is poured into the processing tube 1, the grain can be guided through the tapered plate 32 so as to be piled up on the annular plate 31. The positioning motor 361 is started, the positioning motor 361 rotates the first gear 363 and the second gear 364 through the support shaft 362, and the first gear 363 rotates the stirring tooth plate 37 through the annular ring gear 36, but the annular plate 31 and the positioning block 38 do not rotate. Therefore, the stirring tooth plate 37 and the positioning block 38 rotate relative to each other, and the stirring tooth plate 37 and the positioning block 38 cooperate with each other to stir and wash the grain, and effectively remove the dust mixed in the grain, thereby enhancing the dust removal effect on the grain. Then, the grain is discharged down together with the washing water through the unloading mechanism.

[0024] As shown in FIG. 3, rice husks are mixed in the grains, and after the grains are washed, dust accumulates in the washing water. Therefore, in order to easily remove the rice husks mixed in the grains and the dust remaining in the washing water, in this embodiment, the actuator 33 further includes a water storage chamber 332. The water storage chamber 332 is opened inside the feed hopper 331, and two communication holes 333 communicating with the water storage chamber are opened symmetrically along the longitudinal direction of the feed hopper 331 at the upper end of the water storage chamber 332. A plurality of spray heads 334 are attached to both side walls in the longitudinal direction of the feed hopper 331, and are arranged at equal intervals and communicate with the communication holes 333. A partition net 335 is detachably provided on the inner wall of the feed hopper 331.

[0025] Furthermore, in this embodiment, two water pumps 336 are symmetrically arranged below the outer wall of the machining tube 1 via a support frame, and a water supply pipe 337 extending to the inner lower side of the machining tube 1 is attached to the input end of the water pump 336, and a first water outlet pipe 339 and a second water outlet pipe 340 are provided at the output end of the water pump 336 via a conversion component 338, and one end of the first water outlet pipe 339 and away from the water pump 336 is connected to the water storage chamber 332.

[0026] In the specific implementation process, a certain amount of water is first injected into the processing tube 1, the water is stored in the inner bottom of the processing tube 1, and then the grain is injected into the delivery hopper 331 and piled up at the upper end of the partition net 335, and the water pump 336 is started. The water pump 336 extracts the water inside the processing tube 1 through the conversion component 338 and discharges it into the water storage chamber 332 through the second water outlet pipe 340. Then, the spray head 334 extracts the water in the water storage chamber 332 and sprays mist. The mist sprayed from the spray heads 334 on both sides of the delivery hopper 331 forms a water curtain, which makes it easier to moisten the grain, and reduces the scattering of dust when the grain is injected into the delivery hopper 331.

[0027] After the grains in the feed hopper 331 are submerged, the chaff in the grains rises to the water surface, and since the grains are smaller than the chaff, the grains settle to the bottom and pass through the partition net 335, then drop through the inlet 11 into the inside of the processing tube 1 to be washed, and the chaff is held at the top of the partition net 335, and then the partition net 335 is removed to remove the chaff, thus realizing the primary washing of the grains. In this way, by combining the partition net with the water washing method, the grains and chaff can be separated, and the chaff can be sieved out.

[0028] As shown in Figures 4 and 5, in order to discharge the washed grains downward from the upper end of the annular plate 31, in this embodiment, the unloading mechanism 39 includes a number of position limiting slide grooves 391 uniformly opened in the circumferential direction at the upper end of the annular plate 31, a stopper plate 392 is slidably connected inside the position limiting slide groove 391, a number of unloading openings 393 are opened at equal intervals along the width direction at the upper end of the position limiting slide groove 391, the stopper plate 392 is opened with a through hole 394, the width of the through hole 394 is larger than the diameter of the unloading opening 393, a linking plate 395 is provided on the stopper plate 392 and on the side away from the tapered plate 32 after passing through the processing tube 1, a seal sleeve 396 connected to the processing tube 1 is slidably covered on the outer wall of the stopper plate 392, and a number of compression springs 397 are provided between the linking plate 395 and the seal sleeve 396.

[0029] In this embodiment, the seal sleeve 396 can seal the gap between the processing tube 1 and the stop plate 392, and prevent water from seeping out of the processing tube 1. In addition, the compression spring 397 always applies a contraction force to the interlocking plate 395 and the stop plate 392 so that the interlocking plate 395 and the stop plate 392 always tend to move away from the processing tube 1 in the initial state, and at this time, the through holes 394 on the stop plate 392 and the loading / unloading port 393 are alternately arranged to seal the loading / unloading port 393, thereby lengthening the time for which the mixing tooth plate 37 mixes and washes the grains, and further improving the washing effect.

[0030] As shown in Figures 2, 4, 5 and 6, the loading / unloading mechanism 39 further includes a driving cylinder 401, which is attached to the center of the lower end of the taper plate 32. The telescopic end of the driving cylinder 401 is provided with a water filter plate 51. Two push rods are symmetrically arranged along the upper end of the water filter plate 51 along the driving cylinder 401. The upper ends of the two push rods are provided with closing blocks which are fitted into the inlet 11 together after passing through the taper plate 32. An annular support plate 402 is attached to the upper end of the water filter plate 51. A plurality of support blocks 403 are uniformly arranged on the upper end of the annular support plate 402, which are distributed in an annular shape. A guide slide groove is opened along the upper end of the support block 403 along the longitudinal direction, and a support pole 404 is slidably connected in the guide slide groove. A support spring 405 is provided between the support pole 404 and the side wall of the guide slide groove close to the driving cylinder 401.

[0031] Furthermore, a plurality of mounting blocks 406 corresponding to the positions of the support blocks 403 are uniformly attached to the inclined surface at the lower end of the tapered plate 32, a slide groove is formed at the lower end of the mounting block 406, and an engaging slide block 407 is slidably connected within the slide groove. A groove is formed at the lower end of the engaging slide block 407 to engage with the upper end of the support column 404. A first pull rope 408 is provided on the side of the engaging slide block 407 away from the drive cylinder 401, and one end of the first pull rope 408 away from the engaging slide block 407 is connected to the stop plate 392 after passing through the tapered plate 32.

[0032] In the initial state, the support spring 405 constantly exerts a pressing force on the support column 404 so that the support column 404 tends to move away from the driving cylinder 401, and the engaging slide block 407 is positioned at the bottom of the slide groove by the stop plate 392 and the pull rope, at this time the upper and lower positions of the support column 404 and the engaging slide block 407 correspond to each other, the driving cylinder 401 is in a contracted state, the water filter plate 51 is at the highest position, and the push rod drives the closing block to close the inlet 11, so that the grain injected into the feed hopper 331 is sufficiently immersed in water, and the chaff mixed with the grain can be completely removed.

[0033] In a specific implementation process, the driving cylinder 401 is started, and the driving cylinder 401 moves the water filter plate 51 downward, and the water filter plate 51 synchronously moves the push rod and the closing block to release the closing effect on the inlet 11, so that all the grain and water inside the feed hopper 331 falls through the inlet 11 to the upper end of the annular plate 31 to be washed.

[0034] When the grain washing is completed, the driving cylinder 401 moves the water filter plate 51 upward, and the water filter plate 51 moves the annular support plate 402, the support block 403 and the support column 404 upward as a whole, so that the support column 404 abuts against the groove at the lower end of the engaging slide block 407 and applies an upward pressing force to the engaging slide block 407. The engaging slide block 407 moves along the slide groove to the side closer to the driving cylinder 401 due to the pressing force, and at the same time, the support column 404 moves along the guide slide groove to the side of the driving cylinder 401, thereby moving the engaging slide block 407 toward the engaging slide block 407. The ride block 407 applies a pulling force to the stop plate 392 through the first pull rope 408, so that the through hole 394 on the stop plate 392 overlaps with the loading / unloading port 393, facilitating the grain and water to be discharged through the loading / unloading port 393; during this time, the annular ring gear 36 continuously rotates the stirring tooth plate 37 to facilitate the annular plate 37 to sweep the grain at the upper end of the annular plate 31 into the loading / unloading port 393, and ensures that the grain at the upper end of the annular plate 31 completely passes through the loading / unloading port 393 and falls, thereby realizing automatic unloading of grain.

[0035] Next, the driving cylinder 401 moves the water filter plate 51 downward to reset it, and the water filter plate 51 moves the annular support plate 402, the support block 403, and the support pillar 404 downward to reset them all together. At this time, the retaining plate 392 resets under the action of the compression spring 397 to re-close the loading / unloading opening 393, and the engaging slider 407 and the support pillar 404 are also reset respectively.

[0036] As shown in Figure 1, Figure 7 and Figure 8, the grain is soaked in water after washing, and the water contains dust, so the grain and water need to be separated to complete the grain dust removal process. Specifically, the filtration unit 5 includes a water filtration plate 51 attached to the center of the inner wall of the processing tube 1, and a plurality of drainage holes distributed in a ring shape are opened in the water filtration plate 51. A plurality of sector plates 52 distributed in a ring shape are hingedly connected to the upper ends of the drainage holes via a first torsion spring. The first torsion spring constantly applies a downward torsional force to the sector plate 52, and the plurality of sector plates 52 form a complete circular plate due to the torsional force of the first torsion spring. A fixed frame 53 is provided on the inner wall of the processing tube 1 and below the water filtration plate 51. A protruding bar 54 is attached to the upper end of the fixed frame 53 corresponding to the position of the drainage hole. The diameter of the protruding bar 54 is smaller than the diameter of the drainage hole. A first through hole is opened on any side of the outer wall of the processing tube 1 and above the water filtration plate 51, and a first opening / closing plate 57 is hingedly connected to the inner wall of the first through hole.

[0037] Furthermore, in this embodiment, two vertically arranged filtering mesh plates 55 are attached to the inner wall of the processing tube 1 and below the fixed frame 53, and a dust removal pad 56 is removably provided between the two filtering mesh plates 55, a second through hole is opened on the outer wall of the processing tube 1 and below the first opening / closing plate 57 and above the filtering mesh plate 55, a second opening / closing plate 58 is hingedly connected to the inner wall of the second through hole, and a stirring / drying mechanism 59 is provided on the inner wall of the processing tube 1.

[0038] Furthermore, as shown in Figures 8 and 9, an annular internal hollow pipe 341 is provided inside the machining tube 1 and below the annular plate 31, and a plurality of liquid discharge holes 342 are uniformly provided in the annular internal hollow pipe 341 on the side closer to the inside of the machining tube 1, and one end of the second water outlet pipe 340 away from the water pump 336 is connected to the annular internal hollow pipe 341.

[0039] In the specific implementation process, when the driving cylinder 401 moves the water filtering plate 51 to the lowest position, the grain and water on the upper end of the annular plate 31 are both discharged through the loading and unloading port 393 and fall to the upper end of the water filtering plate 51. At this time, the fan-shaped plate 52 of the water filtering plate 51 collides with the ejecting bar 54, and the fan-shaped plate 52 can be pushed up through the ejecting bar 54, and a gap appears between the two adjacent fan-shaped plates 52, but the width of the gap is smaller than the diameter of the grain. Therefore, the water and some dust on the upper end of the water filtering plate 51 flow down through the gap and fall onto the water filtering plate 55, so that only grain remains on the upper end of the water filtering plate 51, thereby realizing rapid separation between the grain and the water. Then, the water passes through the filter mesh hole plate 55 and the dust removing pad 56, and the water is filtered through the dust removing pad 56, and the dust is retained inside the dust removing pad 56, and the clean water after filtration passes through the dust removing pad 56 and falls to the bottom of the processing tube 1.

[0040] Then, the water pump 336 extracts the water at the bottom of the processing tube 1, and discharges the water through the conversion unit 338 to the second water outlet pipe 340. The second water outlet pipe 340 directs the water into the inside of the annular internal hollow pipe 341, and then the water in the annular internal hollow pipe 341 sprays out through the liquid discharge hole 342 to the upper end of the water filter plate 51, making it easier to wash the grains secondarily and completely removing the dust remaining on the grain surface. In addition to enhancing the dust removal effect of the grains, no dust scattering occurs during dust removal, and the influence of the air environment is avoided. After cleaning, the water and dust are discharged again through the gaps in the fan-shaped plate 52.

[0041] Next, the grain on the upper end of the water filtering plate 51 is dried by the stirring and drying mechanism, and then the first opening / closing plate 57 is opened so that the grain can be removed from the first through hole, and the second opening / closing plate 58 is opened so that the dust removal pad 56 can be removed from the second through hole and replaced, and then the first opening / closing plate 57 and the second opening / closing plate 58 are closed.

[0042] As shown in FIG. 10, the first through hole is located on one side of the water filter plate 51, so that the upper end of the water filter plate 51 cannot extract grains on the side far from the first through hole. Based on this, in this embodiment, a corresponding supporting and discharging unit 2 is provided. Specifically, the supporting and discharging unit 2 further includes a receiving plate 22. The receiving plate 22 is hinged to the center of the lower end of the processing tube 1. The receiving plate 22 is provided at the upper end of the support base 21. Two storage slide grooves 23 are symmetrically opened along the receiving plate 22 at the upper end of the support base 21. The inner bottom walls of the two storage slide grooves 23 are gradually inclined downward from one side of the support base 21 to the other side. At the lower end of the processing tube 1, two auxiliary plates 24 are symmetrically slidably connected in the storage slide grooves 23 along the receiving plate. In the initial state, the heights of the upper ends of the two auxiliary plates 24 are parallel to each other, and the processing tube 1 is in a vertical state.

[0043] Furthermore, in this embodiment, two mounting holes are opened symmetrically along the longitudinal direction of the auxiliary plate 24, and a support block 25 is slidably connected inside the mounting holes. Two positioning plates 26 are symmetrically provided along the receiving plate at the upper end of the support base 21. Two bidirectional screws 27 that pass through the support block 25 are symmetrically connected between the two positioning plates 26 and can rotate freely. The two bidirectional screws 27 are connected between them by a belt transmission, and the support block 25 engages with the bidirectional screws 27 by a screw connection.

[0044] In addition, two sets of bidirectional screws 27 are provided on the outer wall of the bidirectional screw 27 near both ends thereof, so that the support blocks 25 can move relative to each other or in the opposite direction when the bidirectional screws 27 are rotated. The bidirectional screws 27 are self-locking screws that can be automatically locked after rotation and will not rotate spontaneously.

[0045] In a specific implementation process, after the first opening / closing plate 57 is opened, one of the two-way screws 27 is rotated, and the two auxiliary plates 24 are moved in the opposite direction during the rotation of the two-way screws 27, and the support block 25 moves the auxiliary plate 24 to move along the storage slide groove 23. Since the inner bottom wall of the storage slide groove 23 is inclined, a step-like difference in height occurs between the two auxiliary plates 24, and the processing tube 1 is inclined toward the side where the first through hole is opened, and at this time the support block 25 slides adaptively within the mounting hole, and the grains at the upper end of the water filter plate 51 are collected in the first through hole, making it easy to collect the grains. After the grains are collected, the first opening / closing plate 57 is closed, the two-way screws 27 are rotated in the opposite direction, and the two-way screws 27 drive the movement of the auxiliary plate 24 via the support block 25 to reset it.

[0046] Example 2 As shown in Fig. 8 and Fig. 11, in addition to the first embodiment, in order to perform the primary washing and secondary washing of grains, the water pump 336 needs to discharge water into the water storage chamber 332 and the annular inner hollow pipe 341, respectively, so that the output end of the water pump 336 needs to be connected to the first water outlet pipe 339 and the second water outlet pipe 340, respectively. Specifically, the conversion component 338 includes a hollow fixed block 343, and the outer wall of the processing tube 1 is provided with two hollow fixed blocks 343 located above the water pump 336, and the hollow fixed block 343 is slidably connected thereto with a conversion slide block 344, and the conversion slide block 344 is symmetrically opened with two water outlet holes 345 along the longitudinal direction, which are connected to the first water outlet pipe 339 and the second water outlet pipe 340, respectively. The lower end of the conversion slide block 334 is provided with a water outlet pipe 345. A support tube 346 is provided which is connected to the output end of the water pump 336, and two pressure springs 347 are symmetrically attached between the conversion slide block 344 and the side of the hollow fixed block 343 closer to the processing tube 1. The pressure springs 347 always apply a pressure force to the conversion slide block 344 so that the conversion slide block 344 tends to move away from the processing tube 1. In the initial state, the first water outflow pipe 339 is connected to the support tube 346 at the output end of the water pump 336.

[0047] In addition, in this embodiment, the inner wall of the processing tube 1 is symmetrically provided with two escape grooves corresponding to the position of the water pump 336, two interlocking blocks 348 are attached to the outer wall of the water filtering plate 51 and slidably connected within the escape grooves, and the upper and lower side walls of the water filtering plate 51 are both provided with sealing elastic plates connected to the inner walls of the escape grooves, which can seal the escape grooves and prevent the water in the processing tube 1 from entering into the escape grooves, and an extension hole is opened at the lower end of the escape groove, and a push-pull rod 349 is provided at the lower end of the interlocking block 348 and slidably connected within the extension hole, and a second pull rope 350 is provided between the push-pull rod 349 and the conversion slide block 344.

[0048] In a specific implementation process, when the driving cylinder 401 moves the water filtering plate 51 upward, the grain needs to be first washed in the feed hopper 331. At this time, the water filtering plate 51 moves the interlocking block 348 and the push-pull rod 349 upward as a whole, and the push-pull rod 349 pulls the conversion slide block 344 through the second pulling rope 350, and moves the conversion slide block 344 to the side closer to the processing tube 1, thereby changing the positions of the first water outlet pipe 339 and the second water outlet pipe 340, and connecting the second water outlet pipe 340 to the output end of the water pump 336. Then, the water pump 336 discharges water through the second water outlet pipe 340 to perform the first washing of the grain.

[0049] Then, the driving cylinder 401 moves the water filter plate 51 downward, and the water filter plate 51 moves the interlocking block 348 and the push-pull rod 349 downward to reset, at this time the conversion slide block 344 resets and controls the communication between the first water outlet pipe 339 and the output end of the pump 336 by the pressure spring 347. At this time, the grain is at the upper end of the water filter plate 51, so the pump 336 discharges water through the first drain pipe 339 to perform secondary washing processing of the grain. From the above, the conversion slide block 344 can be controlled so that the conversion slide block 344 changes the communication state between the first water outlet pipe 339, the second water outlet pipe 340 and the output end of the water pump 336 according to the up and down movement of the water filter plate 51, and thus the water can be discharged according to the grain washing procedure, which is simple to operate and does not require separate driving.

[0050] As shown in FIG. 12, when converting the first water outlet pipe 339 and the second water outlet pipe 340, the conversion slide block 344 needs to slide inside the hollow fixed block 343, so the water outlet hole 345 on the conversion slide block 344 may not be accurately aligned with the output end of the water pump 336. To avoid this problem, in this embodiment, the conversion component 338 further includes an annular support plate 351 on the inner wall of the support tube 346, a receiving hole is opened at the lower end of the hollow fixed block 343, a hemispherical support block 353 is provided at the upper end of the annular support plate 351 and is slidably connected in the receiving hole through a protruding spring 352, a water tank is opened at the upper end of the hemispherical support block 353, and a plurality of connection holes 354 are evenly opened at the lower end of the water tank, which are distributed in a ring shape.

[0051] In a specific implementation process, while the conversion slide block 344 is sliding, a pressing force is applied to the hemispherical protruding block 353, causing the hemispherical protruding block 353 to contract into the receiving hole. When any of the water outflow holes 345 on the conversion slide block 344 is located above the hemispherical protruding block 353, the hemispherical protruding block 353 will be pushed upward by the protruding spring 352 to abut against the lower end of the water outflow hole 345, thereby positioning the conversion slide block 344 and accurately aligning the water outflow hole 345 with the support tube 346, and further, accurately aligning the first water outflow pipe 339 or the second water outflow pipe 340 with the water outlet end of the water pump 336, so as not to affect the normal drainage of the water pump 336 through the water tank and connection hole 354.

[0052] Example 3 As shown in Figures 7, 8, 13 and 14, in addition to the second embodiment, it is necessary to perform drying treatment in a timely manner to prevent the soaked grain from spoiling or sprouting. Specifically, the stirring and drying mechanism 59 includes a hollow annular frame 591, the hollow annular frame 591 is rotatably connected to the lower end of the annular plate 31, the outer wall of the hollow annular frame 591 is uniformly provided with a plurality of teeth that are distributed in an annular shape and mesh with the second gear 364, the inner wall of the hollow annular frame 591 is uniformly provided with a plurality of hollow support rods 592 that are distributed in an annular shape, and a hollow rectangular plate 593 is provided at the lower end of the hollow support rod 592 via a telescopic tube, and the hollow annular frame 591, the hollow support rod 592 and The hollow annular frame 591 is connected to the hollow rectangular plate 593, and a plurality of air pumps 594 are uniformly arranged in a ring shape at the lower end of the hollow annular frame 591, the output ends of the air pumps 594 extend to the inside of the hollow annular frame 591, and a ring-shaped heating mesh 595 is provided between the hollow annular frame 591 and the hollow support rod 592. A plurality of exhaust holes 596 are drilled on the upper and lower sides of the hollow rectangular plate 593, and a plurality of positioning rods 597 arranged alternately with the exhaust holes 596 are provided on the upper and lower side walls of the hollow rectangular plate 593.

[0053] Furthermore, in this embodiment, connecting plates 598 are attached to both side walls in the longitudinal direction of hollow rectangular plate 593 via interlocking rods, and two support shafts 362 are symmetrically arranged along the hollow rectangular plate on the opposing sides of the two connecting plates 598, and a sweep-out plate 599 is rotatably covered on the outer wall of support shaft 362 via a second torsion spring, and the arrangement of the second torsion spring allows sweep-out plate 599 to always maintain a vertical state without being subjected to any external force.

[0054] In a specific implementation process, after the second cleaning of the grain, the positioning motor 361 rotates the second gear 364 via the support shaft 362, and the second gear 364 rotates the hollow annular frame 591 via its teeth, and the hollow annular frame 591 rotates the hollow support rod 592, the hollow rectangular plate 593 and the sweeping plate 599 as a whole, stirring and stirring the grain on the upper end of the water filtering plate 51, so that the water in the grain flows out rapidly through the gap between the fan-shaped plates 52, and an adaptive tilt is generated when the sweeping plate 599 comes into contact with the grain.

[0055] At the same time, the air pump 594 and the annular heating net 595 are started, and the air pump 594 pumps air into the hollow annular frame 591, and the air inside the hollow annular frame 591 passes through the annular heating net 595 to form a hot air current, which then enters the hollow support rod 592, the telescopic tube, the hollow rectangular plate 593 in turn, heating them and the positioning rod 597, so that the evaporation of moisture on the grain surface can be accelerated when the heated hollow support rod 592, the hollow rectangular plate 593 and the positioning rod come into contact with the grain, and the hot air current inside the hollow rectangular plate 593 can be ejected through the exhaust holes 596, increasing the heating area of ​​the grain and further improving the drying efficiency of the grain.

[0056] After drying of the grain is complete, the first opening and closing plate 57 is opened while the sweep plate 599 continues to agitate the grain and move it towards the first passage hole for easier removal of the grain.

[0057] During operation, step 1 first injects a certain amount of water into the processing tube 1, the water is stored in the inner bottom of the processing tube 1, and then the grain is injected into the feed hopper 331 and piled up at the upper end of the partition net 335, and the water pump 336 is started. The water pump 336 extracts the water inside the processing tube 1 through the conversion component 338 and discharges it into the water storage chamber 332 through the second water outlet pipe 340. Then, the spray head 334 extracts the water in the water storage chamber 332 and sprays mist. The mist sprayed from the spray heads 334 on both sides of the feed hopper 331 forms a water curtain, which makes it easier to moisten the grain, and can reduce the scattering of dust when the grain is injected into the feed hopper 331.

[0058] After the grain in the feed hopper 331 is submerged, the chaff in the grain rises to the water surface, the grain settles to the bottom and passes through the partition net 335, the chaff is retained at the upper end of the partition net 335, and then the partition net 335 is removed to remove the chaff, thereby achieving the primary washing of the grain.

[0059] Step 2: start the driving cylinder 401, which moves the water filter plate 51 downward, which synchronously moves the push rod and the closing block to release the closing effect on the inlet 11, and the whole grain and water in the feed hopper 331 falls through the inlet 11 to the upper end of the annular plate 31 for cleaning. At the same time, the grain can be guided to the upper side of the annular plate 31 through the taper plate 32, and the positioning motor 361 is started, which rotates the first gear 363 and the second gear 364 through the support shaft 362, and the first gear 363 rotates the stirring tooth plate 37 through the annular ring gear 36. The stirring tooth plate 37 and the positioning block 38 cooperate with each other to stir and clean the grain, and the dust mixed in the grain can be effectively removed.

[0060] Step 3: when the grain washing is completed, the driving cylinder 401 moves the water filtering plate 51 upward, and the water filtering plate 51 moves the annular support plate 402, the support block 403 and the support pillar 404 upward as a whole, and due to the engagement between the support pillar 404 and the engaging slide block 407, the engaging slide block 407 moves to the side closer to the driving cylinder 401, and at the same time, the support pillar 404 moves to the side of the driving cylinder 401 along the guide slide groove, and the engaging slide block 407 applies a pulling force to the stop plate 392 through the first pulling rope 408, so that the through hole 394 on the stop plate and the loading / unloading port 393 overlap, facilitating the grain and water to be discharged through the loading / unloading port 393.

[0061] During this time, the annular ring gear 36 continuously rotates the agitator tooth plate 37 to facilitate the agitator tooth plate 37 to sweep the grain at the upper end of the annular plate 31 to the unloading port 393, and ensures that the grain at the upper end of the annular plate 31 completely passes through the unloading port 393 and falls, thereby realizing automatic unloading of the grain.

[0062] In the fourth step, when the driving cylinder 401 moves the water filtering plate 51 to the lowest position, the fan-shaped plate 52 of the water filtering plate 51 collides with the ejection bar 54, and the fan-shaped plate 52 can be pushed upward through the ejection bar 54, and a gap appears between the two adjacent fan-shaped plates 52. The water and some dust at the upper end of the water filtering plate 51 flow downward through the gap and fall onto the water filtering plate 55, so that only grains remain at the upper end of the water filtering plate 51, thereby realizing rapid separation between grains and water. Then, the water is filtered through the dust removing pad 56, and the clean water after filtration passes through the dust removing pad 56 and falls to the bottom of the processing tube 1.

[0063] Next, the water pump 336 extracts the water from the bottom of the processing tube 1 and discharges it into the second water outlet pipe 340, which directs the water into the inside of the annular internal hollow pipe 341. Then, the water in the annular internal hollow pipe 341 is sprayed out through the liquid discharge hole 342 to the upper end of the water filter plate 51, which facilitates the secondary washing of the grains and completely removes the dust remaining on the grain surface. In addition to enhancing the dust removal effect of the grains, no dust scattering occurs during dust removal and avoids the influence of the air environment. After cleaning, the water and dust are discharged again through the gaps in the fan-shaped plate 52.

[0064] In the fifth step, the second gear 364 rotates the hollow annular frame 591 through its teeth, and the hollow annular frame 591 rotates the hollow support rod 592, the hollow rectangular plate 593 and the sweeping plate 599 as a whole, thereby stirring and stirring the grains on the upper end of the water filtering plate 51, so that the water in the grains flows out rapidly through the gaps between the fan-shaped plates 52, and an adaptive tilt is generated when the sweeping plate 599 comes into contact with the grains.

[0065] At the same time, the air pump 594 and the annular heating net 595 are started, and the air pump 594 pumps air into the hollow annular frame 591, and the air inside the hollow annular frame 591 passes through the annular heating net 595 to form a hot air current, which then enters the hollow support rod 592, the telescopic tube, the hollow rectangular plate 593 in turn, heating them and the positioning rod 597, so that the evaporation of moisture on the grain surface can be accelerated when the heated hollow support rod 592, the hollow rectangular plate 593 and the positioning rod come into contact with the grain, and the hot air current inside the hollow rectangular plate 593 can be ejected through the exhaust holes 596, increasing the heating area of ​​the grain and further improving the drying efficiency of the grain.

[0066] The above steps can perform primary washing of the grain, stirring washing, rapid separation of the grain and water, secondary washing and rapid drying of the grain, thereby improving the dust removal effect of the grain. After washing, the grain is in a dry state after drying, and there is no need to worry about the grain rotting or sprouting.

[0067] In step 6, after the grain drying is completed, the first opening / closing plate 57 is opened, and one of the two-way screws 27 is further rotated, and the two auxiliary plates 24 are moved in the opposite direction during the rotation of the two-way screws 27, and the support plate 25 moves the auxiliary plates 24 to move along the storage slide groove 23, so that a stepwise difference in height occurs between the two auxiliary plates 24, and the processing tube 1 is tilted toward the side where the first through hole is open, so that the grain at the upper end of the drainage plate 51 is collected in the first through hole. At this time, the sweeping plate continues to stir the grain, and moves the grain to the first through hole to make it easier to take out.

[0068] Thereafter, the second opening / closing plate 58 is opened, the dust removal pad 56 is removed from the second through hole and replaced, the first opening / closing plate 57 is closed, and the bidirectional screw 27 can be rotated in the reverse direction. The bidirectional screw 27 then moves the auxiliary plate 24 via the support block 25 to reset it, and the processing tube 1 is returned to the vertical state.

[0069] By repeating the above steps, a cycle of washing, drying and removing the grain can be completed, thereby improving work efficiency.
