[0028] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model rather than limiting it.

[0029] The following is a further detailed description of this embodiment in combination with the attached Figures 1 - 5 drawings.

[0030] As Figures 1 - 3As shown, a malt crushing device in this embodiment includes a box body 100, a cavity 201 with an opening facing upward is provided in the box body 100, a crushing assembly for malt crushing is provided in the middle of the cavity 201, a box body 110 is provided at the opening of the cavity 201, a cavity 202 with openings at both ends is provided in the box body 110, slots 301 opening downward and connected to the cavity 202 are provided on opposite side walls of the box body 110, mounting plates 210 are provided on the bottom walls of the slots 301, rotating plates 220 are provided at the lower ends of the mounting plates 210, and the upper ends of the rotating plates 220 are hingedly connected to the mounting plates 210, and moving components are provided on the opposite side walls of the box body 110, and the moving components are used to drive the lower ends of the two rotating plates 220 to move closer to or away from each other, so as to adjust the size of the opening at the lower end of the cavity 202.

[0031] In this embodiment, the malt is poured into the cavity 202 from the opening of the cavity 202, and the malt in the cavity 202 flows into the cavity 201 from the lower opening of the cavity 202. When the malt is in the cavity 201, the crushing component in the cavity 201 crushes the malt, thereby achieving the crushing process of the malt.

[0032] The crushing assembly includes a crushing roller 250 which is relatively arranged in the cavity 201 and can rotate. Lugs are fixedly installed at both ends of the crushing roller 250. The lugs are respectively inserted into the side walls of the cavity 201 to realize the rotatable installation of the crushing roller 250 in the cavity 201. Two motors 170 are fixedly installed outside the box 100. The output shafts of the two motors 170 are connected to the corresponding lugs, so that the motors 170 can drive the lugs to rotate, that is, the two crushing rollers 250 can rotate to crush the malt in the cavity 201.

[0033] The opening formed between the two rotating plates 220 is just opposite to the matching position of the two crushing rollers 250, so that the two crushing rollers 250 can better crush the malt flowing into the cavity 201, wherein the lower ends of the rotating plates 220 are driven to approach each other by the moving assembly, so that the lower end opening of the cavity 202 becomes smaller, at this time, the malt in the cavity 202 begins to flow slowly and in small quantities into the cavity 201, so that the crushing rollers 250 can better crush the malt. Compared with the existing one, this malt crushing device can avoid a large amount of malt flowing into the cavity 201 at the same time, resulting in the crushing rollers 250 crushing part of the malt unevenly, thereby affecting the subsequent processing of the malt;

[0034] When the lower ends of the rotating plates 220 are close to each other, making the lower end opening of the cavity 202 smaller, the malt may be blocked on the two rotating plates 220, causing the malt to be unable to flow into the cavity 201. At this time, the lower ends of the two rotating plates 220 can be driven by the moving component to continuously move away from or close to each other, so as to clear the blocked malt, thereby preventing the malt from being blocked on the two rotating plates 220, causing the malt to be unable to enter the cavity 201 for crushing. After the malt is cleared, the lower ends of the two rotating plates 220 can be adjusted to a suitable position by the moving component.

[0035] Among them, the mounting plate 210 is fixedly mounted on the bottom wall of the notch 301, a plurality of mounting grooves penetrating the mounting plate 210 are opened on the side wall of the mounting plate 210, a plurality of mounting blocks 360 are fixedly mounted on the upper side wall of the rotating plate 220 and one end of which is inserted into the corresponding mounting grooves, a through rod 211 having one end penetrating the plurality of mounting blocks 360 is installed on the side wall of the mounting plate 210, and both ends of the through rod 211 are threadedly mounted in the mounting plate 210, thereby realizing the hinged installation of the rotating plate 220 on the mounting plate 210, so that the moving assembly can drive the lower ends of the two rotating plates 220 to move closer to or away from each other in the cavity 202, and adjust the size of the opening at the lower end of the cavity 202;

[0036] The opposite side walls of the cavity 202 are fixedly mounted with blocks 230, and the cavity 202 is fixedly mounted with a filter plate 120 whose two ends are overlapped on the corresponding blocks 230. The filter plate 120 is installed in the cavity 202 by overlapping the two ends of the filter plate 120 on the blocks 230. When the malt flows from the cavity 202 into the cavity 201, the malt will be filtered through the filter plate 120. The filter plate 120 can remove the granular debris (such as stones) in the malt, thereby preventing the malt after being crushed by the crushing roller 250 from being mixed with granular debris, which affects the subsequent processing of the malt. When a large number of granular debris are accumulated on the filter plate 120, the granular debris on the filter plate 120 can be cleaned by taking the filter plate 120 out of the cavity 202.

[0037] A discharge port 101 communicating with the cavity 201 is provided on one side wall of the box body 100 and at the lower end thereof, and a fixing block 240 is fixedly installed on the bottom wall of the cavity 201. A guide slope 241 is provided on the fixing block 240. When the malt in the cavity 201 is crushed by the crushing roller 250, the crushed malt will fall onto the fixing block 240, and the malt on the fixing block 240 will slide along the guide slope 241, so that the malt can slide out of the cavity 201 from the discharge port 101, thereby facilitating the staff to collect the crushed malt, and the practicability is strong.

[0038] During actual use, a lapping plate 160 is fixedly installed on the side wall of the box body 110, and the lapping plate 160 is lapped at the opening of the cavity 201 to realize the installation of the box body 110 in the box body 100.

[0039] As Figures 1 - 3 shown, in this embodiment, through grooves 302 that are opposite and penetrate the box body 110 are respectively provided on the opposite side walls of the cavity 202. The through grooves 302 are arranged along their length directions. A movable plate 310 that is opposite and movable is provided in the cavity 202. The movable plate 310 respectively abuts against the corresponding rotating plate 220. Connecting plates 311 that penetrate the corresponding through grooves 302 at one end and extend out of the box body 110 are provided at both ends of the movable plate 310. Connection seats 312 are provided on the extending ends of the connecting plates 311. Fixed seats 320 are provided on the opposite outer side walls of the box body 110 and near the upper and lower ends;

[0040] The moving assembly includes a lead screw 330 arranged between two opposite fixed seats 320. The lead screw 330 is rotatably arranged. A lifting block 340 is threadedly sleeved on the lead screw 330. Hinge seats 341 are arranged on the opposite side walls of the lifting block 340. A hinge rod 350 is hinged between the hinge seat 341 and the corresponding connection seat 312. The rotation of the lead screw 330 drives the lifting block 340 to lift, driving the hinge rod 350 to pull the two movable plates 310 closer to or away from each other. Driving members are provided on the opposite side walls of the box body 110, and the driving members are used to drive the corresponding lead screw 330 to rotate.

[0041] In this embodiment, through the arrangement of the through groove 302, the moving plate 310, the connecting plate 311, the connecting seat 312, the fixed seat 320, the lead screw 330, the lifting block 340, the hinge seat 341, the hinge rod 350 and the driving member, by fixedly installing the connecting plate 311 on the moving plate 310 and the connecting plate 311 passing through the through groove 302 at one end, the moving plate 310 is movably installed in the cavity 202. The connecting seat 312 is fixedly installed on the connecting plate 311, the fixed seat 320 is fixedly installed on the box body 110, and both ends of the lead screw 330 are installed on the corresponding fixed seat 320 through bearing seats, realizing the rotational installation of the lead screw 330. When the lead screw 330 is driven to rotate by the driving member, the rotation of the lead screw 330 can drive the lifting block 340 to lift along the lead screw 330. When the lifting block 340 rises, the hinge rods 350 on both sides of the lifting block 340 will drive the two connecting seats 312 to approach each other, that is, the connecting plate 311 moves along the through groove 302 and drives the moving plate 310 to move. At this time, the moving plate 310 pushes the lower ends of the rotating plates 220 to approach each other. When the lifting block 340 descends, the hinge rods 350 on both sides of the lifting block 340 will drive the two connecting seats 312 to move away from each other, that is, the connecting plate 311 moves along the through groove 302 and drives the moving plate 310 to move. At this time, the two moving plates 310 in the cavity 202 move away from each other. When the two moving plates 310 start to move away from each other, the lower end of the rotating plate 220 is affected by its own gravity, so that the lower end of the rotating plate 220 always abuts against the moving plate 310, thereby realizing the mutual separation of the lower ends of the two rotating plates 220;

[0042] Wherein, one end of the hinge rod 350 is inserted into the hinge seat 341, and a first insertion rod 351 passing through the hinge rod 350 is installed on the hinge seat 341. Both ends of the first insertion rod 351 are threadedly installed in the hinge seat 341, realizing the hinge connection of one end of the hinge rod 350 in the hinge seat 341. The other end of the hinge rod 350 is inserted into the connecting seat 312, and a second insertion rod 352 passing through the hinge rod 350 is installed on the connecting seat 312. Both ends of the second insertion rod 352 are threadedly installed in the connecting seat 312, realizing the hinge connection of the other end of the hinge rod 350 in the connecting seat 312. At this time, the lifting block 340 drives the hinge seat 341 to lift, so that the hinge rod 350 on the hinge seat 341 can drive the two moving plates 310 to approach or move away from each other in the cavity 202;

[0043] Wherein, both ends of the hinge rod 350 are respectively connected to the hinge seat 341 and the connecting seat 312, so that the hinge rod 350 can limit the lifting block 340 and prevent the lifting block 340 from rotating circumferentially. Thus, when the lead screw 330 rotates, the lifting block 340 can lift along the lead screw 330;

[0044] During actual use, the side wall of the rotating plate 220 always abuts against the moving plate 310, and the rotating plate 220 is always in an inclined state. When the malt is in the cavity 202, the malt will slide along the inclined surface of the rotating plate 220 and thus slide into the cavity 201 for crushing, which can prevent some malt from accumulating on the rotating plate 220 and being unable to enter the cavity 201 for crushing.

[0045] As Figures 1 - 5 shown, in this embodiment, gears 130 are provided at the upper ends of the lead screws 330.

[0046] The driving member includes racks 140 that are provided on the opposite side walls of the box body 110 and are movable. The racks 140 are respectively engaged with the corresponding gears 130. The movement of the two racks 140 drives the corresponding gears 130 to rotate, and the rotation of the gears 130 drives the corresponding lead screws 330 to rotate.

[0047] In this embodiment, through the arrangement of the gears 130 and the racks 140, by fixedly installing the gears 130 on the lead screws 330, when the racks 140 move, the gears 130 can drive the gears 130 to rotate, that is, the lead screws 330 rotate.

[0048] Among them, slots 501 are respectively formed in the opposite side walls of the box body 110 along their lengths. A block 510 is fixedly installed on the side wall of the rack 140, and one end of the block 510 is inserted into the corresponding slot 501. By inserting the block 510 into the slot 501, the installation of the rack 140 on the box body 110 is realized. At the same time, the rack 140 can also be limited, making the movement of the rack 140 more stable.

[0049] During actual use, both ends of the rack 140 extend out of the box body 110. A pull rod 150 is fixedly installed between the extending ends of the two racks 140. The movement of the pull rod 150 is used to drive the two racks 140 to move. The staff can drive the two racks 140 to move synchronously through the pull rod 150, so that the two lead screws 330 rotate synchronously, which is more convenient during actual use.

[0050] Working principle: First, drive two racks 140 to move through the pull rod 150. The movement of the racks 140 causes the lead screw 330 to rotate, enabling the lifting block 340 on the lead screw 330 to be adjusted up and down. At the same time, drive two moving plates 310 to approach or move away from each other through the hinge rod 350. The mutual approach or separation of the two moving plates 310 will cause the lower ends of the two rotating plates 220 to approach or move away from each other, realizing the adjustment of the opening size at the lower end of the cavity 202. At this time, pour malt into the cavity 202 from the opening of the cavity 202. After being filtered by the filter plate 120, the malt flows into the cavity 201 from the cavity 202. The crushing roller 250 in the cavity 201 will crush the malt flowing into the cavity 201. The crushed malt will fall onto the fixed block 240, and the malt on the fixed block 240 will slide along the guiding inclined surface 241, enabling the malt to slide out of the cavity 201 from the discharge port 101, facilitating the collection of the crushed malt by the staff, and having strong practicability.
