Technical Field

[0001] The utility model relates to the technical field of grain crushing, in particular to a multifunctional grain crushing machine. Background Art

[0002] The grain mill is a continuous feeding operation, suitable for supermarkets, shopping malls and shops to process various grains on site. The grain mill has a wide processing range, for example, rice, black rice, soybeans, red beans, mung beans, black beans, peanuts, lotus seeds, corn, sorghum, barley, sorghum, oats and so on.

[0003] A Chinese patent discloses a dual-function grain grinder with a publication number of CN215029627U, with an application date of 2021.06.24. The patented technology feeds the material through a feed pipe, at which time the first screen and the first screen hole filter the material once, and then the material is crushed by a crushing knife. After crushing, it falls into the interior of the screening box through the upper hole, and the second screen shakes through the operation of the vibration motor. The material is filtered twice by the shaking of the second screen, achieving the advantage of dual functions. However, when the above patent is used, the grains are screened for the first time through the first screen, but the larger grains will not pass through the first screen due to their large volume, so they will gather on the surface of the first screen, thereby affecting the feeding of the grains. Therefore, the inventor provides a multifunctional grain grinder to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0024] like Figure 1 , 5 As shown, a multifunctional grain crusher includes a processing box 10, a discharge trough 12 is opened on the inner bottom side of the processing box 10, a discharge mechanism 11 is installed on the inner bottom side of the discharge trough 12, and the discharge mechanism 11 includes a discharge pipe arranged at the bottom of the discharge trough 12, the discharge pipe is inserted out of the processing box, and the other end is connected to the input end of the discharge pump body, and the output end of the discharge pump body is fixedly connected to the discharge hopper. When in use, by starting the discharge pump body, the discharge pump body sucks the processed grains through the discharge pipe and then discharges them through the discharge hopper (the above is the prior art and is not described in detail here); a feeding mechanism for uniform feeding is fixedly connected to the top of the processing box 10.

[0025] refer to Figure 3 , 6 The top of the processing box 10 is fixedly connected with a transmission cylinder 20, the bottom of the transmission cylinder 20 is cylindrical, the top left side of the transmission cylinder 20 is fixedly connected with a feed hopper 21, the left and right sides of the inside of the transmission cylinder 20 are rotatably connected with threaded leaves 23, the left side of the transmission cylinder 20 is embedded with a first motor 22, and the output end of the first motor 22 is fixedly connected to the threaded leaves 23. A discharge groove 24 is provided on the right side of the bottom of the transmission cylinder 20; the top of the processing box 10 is provided with a feed groove 30, and the feed groove 30 is located directly below the discharge groove 24.

[0026] When in use, the grains are poured into the left side of the interior of the transmission cylinder 20 through the feed hopper 21, and the first motor 22 is started by an external power supply. The output end of the first motor 22 drives the screw blade 23 to rotate, and the screw blade 23 rotates to drive the grains on the left side of the interior of the processing box 10 to the right side. Finally, the grains are discharged from the transmission cylinder 20 through the discharge slot 24 and enter the interior of the processing box 10 through the feed slot 30. Thus, the effect of uniform feeding of the processing box 10 is achieved.

[0027] The grains entering the processing box 10 will be crushed, but since the sizes of the grains entering are different, the time required for crushing is also different. Larger grains require a longer time to crush. At the same time, larger grains may also accumulate inside the processing box 10 due to the long crushing time, affecting the crushing efficiency. Therefore, a structure for distinguishing the sizes of grains is proposed.

[0028] refer to Figure 2 , 6 A support plate 31 is fixedly connected to the right side of the bottom of the feed trough 30, and a tilted filter plate 32 is fixedly connected to the left side of the support plate 31. The filter plate 32 is designed to gradually become lower from left to right. A plurality of groups of fine filter holes 33 are opened on the left side of the top of the filter plate 32, and a plurality of groups of coarse filter holes 34 are opened on the right side surface of the top of the filter plate 32.

[0029] Since the grains are discharged from the left side of the discharge trough 24, the discharged grains first contact the left surface of the filter plate 32, and the smaller grains enter the processing box 10 through the fine filter holes 33, while the larger grains cannot enter the fine filter holes 33 and will roll to the right through the coarse filter holes 34 due to the inclined design of the filter plate 32 and fall into the processing box 10.

[0030] Preferably, a connecting plate 35 is fixedly connected to the right side of the top of the processing box 10, a vibration motor 36 is fixedly connected to the left side of the connecting plate 35, and the output end of the vibration motor 36 is fixedly connected to the support plate 31. When in use, the vibration motor 36 is started by an external power supply, and the output end of the vibration motor 36 drives the connecting plate 35 and the surface of the filter plate 32 to vibrate, which can speed up the grain screening speed and further prevent clogging.

[0031] Preferably, a partition plate 37 is fixedly connected to the bottom of the filter plate 32, and the partition plate 37 is used to separate the grains passing through the fine filter holes 33 and the grains passing through the coarse filter holes 34. Side plates 38 are fixedly connected to the front and rear sides of the filter plate 32, and the side plates 38 are used to prevent the grains from leaking out from the front and rear sides of the top of the filter plate 32.

[0032] Specifically, the left and right sides of the processing box 10 are rotatably connected to rotatable rotating rods 40, and the two rotating rods 40 are fixedly connected to crushing wheels 41, which are arranged directly below a group of coarse filtering holes 34. Therefore, the coarser grains filtered through the coarse filtering holes 34 will fall into the opposite sides of the two crushing wheels 41, and will be crushed by the two crushing wheels 41 rotating in opposite directions before being pulverized.

[0033] refer to Figure 2 , 36. The filter screen 50 is fixedly connected to the left and right sides of the processing box 10. The front and rear sides of the processing box 10 are rotatably connected to the flip rod 51. The surface of the flip rod 51 is fixedly connected to a group of crushing blades 52. The surface of the filter screen 50 is designed to be in an arc shape that conforms to the rotation path of the crushing blade 52, so that the grains filtered from the filter plate 32 will fall on the surface of the filter screen 50. The arc surface of the filter screen 50 has the following advantages over other horizontal surfaces. First, the surface area of ​​the filter screen 50 with an arc surface is larger, thereby accelerating the speed of grain filtering. Second, the filter screen 50 with an arc surface is high at both ends and low in the middle, so the grains will gradually slide to the middle position, so that all the grains can be processed without any crushing dead angles. When in use, the rotating group of crushing blades 52 crush the grains on the surface of the filter screen 50, and the crushed grains will fall into the bottom of the processing box 10 through the filter screen 50.

[0034] refer to Figure 3 A collecting notch 55 is provided on the inner bottom side of the processing box 10, and the collecting notch 55 is in a "Y" shape, so that the crushed grains falling from the filter 50 will fall into the collecting notch 55. Since the top of the collecting notch 55 is inclined to converge toward the middle, the grains falling into the collecting notch 55 will converge to the bottom of the collecting notch 55 and finally be discharged through the discharging mechanism 11.

[0035] Specifically, refer to Figure 4 The front side of the right rotating rod 40 is fixedly connected with a driving gear 42, and the front side of the left rotating rod 40 is fixedly connected with a driven gear 43, the driving gear 42 is meshed with the driven gear 43, the front side of the processing box 10 is fixedly connected with a mounting seat 44, and the rear side of the mounting seat 44 is fixedly connected with a second motor 45, and the output end of the second motor 45 is fixedly connected to the right rotating rod 40; the front side of the left rotating rod 40 is fixedly connected with a synchronous pulley 53, and the front side of the flip rod 51 is fixedly connected with the same synchronous pulley 53, and the outer sides of the two synchronous pulleys 53 are meshed with a transmission belt 54. When in use, the second motor 45 is started by an external power supply, and the output end of the second motor 45 drives the right rotating rod 40 to rotate counterclockwise, and drives the left rotating rod 40 to rotate clockwise through the cooperation of the driving gear 42 and the driven gear 43, so that the two crushing wheels 41 rotate towards each other to crush the coarse grains. At the same time, the rotating rod 40 on the left side drives the flip rod 51 to rotate clockwise through the cooperation of the synchronous pulley 53 and the transmission belt 54, thereby driving a group of crushing blades 52 to rotate and crush the grains. The above mechanism can not only crush the grains but also preliminarily crush the larger grains, thereby achieving the multifunctional effect of the device.

[0036] The working principle of the utility model is: pour the grains into the left side of the interior of the transmission cylinder 20 through the feed hopper 21, and start the first motor 22 through the external power supply at the same time, the output end of the first motor 22 drives the threaded leaf 23 to rotate, and the threaded leaf 23 rotates to drive the grains on the left side of the interior of the processing box 10 to the right, and finally the grains are discharged from the transmission cylinder 20 through the discharge groove 24, and enter the interior of the processing box 10 through the feed groove 30. Thus, the effect of uniform feeding of the processing box 10 is achieved. Since the grains are discharged from the left side of the discharge groove 24, the discharged grains first contact the left side surface of the filter plate 32, and the smaller grains enter the interior of the processing box 10 through the fine filter hole 33, while the larger grains cannot enter the fine filter hole 33 and will roll to the right through the coarse filter hole 34 due to the inclined design of the filter plate 32 and fall into the interior of the processing box 10.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
