Description

Technical Field

[0001] The utility model relates to the technical field of grain processing, in particular to a vibration screening machine for rice processing. Background Art

[0002] Rice screening machine is a common impurity removal equipment for rice processing and storage, used to remove impurities such as husk, dust and diseased rice from harvested rice;

[0003] It is found in actual use that the existing vibration screening machine has the following shortcomings:

[0004] The vibrating screen uses a vibrating motor as a vibration source to throw the material on the screen and move forward in a straight line. The multi-layer screen produces several specifications of oversize and undersize. However, when feeding, the rice falls directly into the screen, resulting in overall accumulation. The outer shell, dust and other debris in the rice are mixed inside. It needs to be vibrated continuously to vibrate them to the surface of the rice before screening. This results in a long screening time for the screening machine, affecting the efficiency of the screening machine in screening rice.

[0005] In addition, although the rice can be separated from the shell, dust and other debris by vibration, during screening, too much shell, dust and other debris are mixed in the rice, and the particle impurities in the rice are prone to block the filter holes of the screen after long-term screening, resulting in a decrease in screening accuracy and affecting the service life of the screen.

[0006] Therefore, the present application provides a vibration type screening machine for rice processing to meet the needs. Utility Model Content

[0007] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a vibration type screening machine for rice processing.

[0008] The technical problem to be solved by the utility model is to provide a vibration type screening machine for rice processing to solve the problems of the existing vibration type screening machine for rice processing.

[0009] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] A vibration screening machine for rice processing comprises: a base, a supporting frame, an exciter group, a screen frame, a spring supporting seat, a feed hopper, an axle seat, a rotating shaft, a baffle, ribs, a relaxation screen plate, a centrifugal fan and a first ash hopper, wherein a plurality of supporting frames are vertically installed on the upper end of the base, a vibrator group is vertically installed on the top of the supporting frame, a screen frame is installed on the upper end of the exciter group through the spring supporting seat, a discharge port is arranged at the left end of the screen frame, a second ash hopper is arranged on the left side of the screen frame, a feed hopper is installed at the upper right end of the screen frame, a shaft seat is installed inside the feed hopper, a rotating shaft is installed in the middle of the shaft seat, a baffle is installed on the rotating shaft, ribs are arranged on the baffle, a relaxation screen plate is installed inside the screen frame, a centrifugal fan is installed at one right end of the screen frame, and a first ash hopper is installed at the other right end of the screen frame.

[0011] Preferably, three sets of shaft seats and rotating shafts are arranged inside the feed hopper, and the three sets of shaft seats and rotating shafts are distributed in a triangle as a whole, dividing the interior of the feed hopper into equal parts.

[0012] Preferably, the rotating shaft is transversely installed inside the feed hopper, and the rotating shaft and the baffle are movably connected to the feed hopper through a shaft seat.

[0013] Preferably, two groups of baffles are installed on the rotating shaft, and the two groups of baffles are mirror-symmetrically located on the left and right sides of the rotating shaft respectively.

[0014] Preferably, the baffle is rectangular, and a plurality of groups of ribs are evenly distributed on the surface of the baffle.

[0015] Preferably, the ribs are in the shape of long strips, protrude from the surface of the baffle, and are arranged obliquely.

[0016] Preferably, the centrifugal fan and the first ash hopper are respectively located on the left and right sides of the lower end of the feed hopper, the centrifugal fan and the first ash hopper are on the same axis, and the centrifugal fan and the first ash hopper are both connected to the screen frame.

[0017] When the rice to be screened is poured into the feed hopper, the rice is poured onto the baffle of the rotating shaft due to gravity, so that the baffle continuously drives the rotating shaft to rotate, and the rotating baffle can disturb and disperse the rice. The inclined ribs can prevent the rice from sliding down directly from the baffle, thereby extending the moving path of the rice. By disrupting and dispersing the rice when pouring it, the rice with a larger weight falls first due to gravity, and the outer shell, dust and other sundries with a lighter weight fall and cover the rice later. The outer shell, dust and other sundries mixed in the rice can be separated from the outer layer of the rice in advance, so that the sundries can be directly separated after vibration screening, thereby reducing the screening time of the screening machine and effectively improving the screening efficiency of the screening machine.

[0018] When feeding, the rotating baffle can disturb and disperse the rice. When the intercepted rice falls, the centrifugal fan on the side blows air to the side of the first ash hopper, and the scattered shells, dust and other light debris can be blown horizontally by the wind and blown into the first ash hopper, thereby reducing the shells, dust and other debris in the rice before screening, avoiding excessive shells, dust and other debris in the rice from gathering and clogging the screen holes, which can ensure the screening accuracy and extend the service life of the screen.

DETAILED DESCRIPTION

[0026] like Figure 1 , Figure 2 and Figure 3The vibration screening machine for rice processing shown in the figure comprises: a base 1, a support frame 2, a vibrator group 3, a screen frame 4, a spring support seat 5, a feed hopper 6, a shaft seat 7, a rotating shaft 8, a baffle 9, a rib 10, a relaxation screen plate 11, a centrifugal fan 12 and a first ash hopper 13. A plurality of groups of support frames 2 are vertically installed on the upper end of the base 1, and a vibrator group 3 is vertically installed on the top of the support frame 2. The upper end of the vibrator group 3 is installed with a screen frame through the spring support seat 5. 4, a discharge port 401 is arranged at the left end of the screen frame 4, a second ash hopper 402 is arranged on the left side of the screen frame 4, a feed hopper 6 is installed at the upper right end of the screen frame 4, a shaft seat 7 is installed inside the feed hopper 6, a rotating shaft 8 is installed in the middle of the shaft seat 7, a baffle plate 9 is installed on the rotating shaft 8, and a rib 10 is arranged on the baffle plate 9, a relaxation screen plate 11 is installed inside the screen frame 4, a centrifugal fan 12 is installed at one end of the right side of the screen frame 4, and a first ash hopper 13 is installed at the other end of the right side of the screen frame 4.

[0027] In this embodiment, three sets of shaft seats 7 and rotating shafts 8 are arranged inside the feed hopper 6. The three sets of shaft seats 7 and rotating shafts 8 are distributed in a triangular shape as a whole, dividing the interior of the feed hopper 6 into equal parts. When the rice to be screened is poured into the feed hopper 6, the rice is poured onto the baffle 9 of the rotating shaft 8 due to gravity, so that the baffle 9 continuously drives the rotating shaft 8 to rotate, and the rotating baffle 9 can disturb and disperse the rice.

[0028] In this embodiment, the rotating shaft 8 is transversely installed inside the feed hopper 6, and the rotating shaft 8 and the baffle 9 are movably connected to the feed hopper 6 through the shaft seat 7.

[0029] In this embodiment, two groups of baffles 9 are installed on the rotating shaft 8 , and the two groups of baffles 9 are mirror-symmetrically located on the left and right sides of the rotating shaft 8 .

[0030] In this embodiment, the baffle 9 is rectangular, and a plurality of groups of ribs 10 are evenly distributed on the surface of the baffle 9. The rectangular baffle 9 has a large cross-sectional area to ensure the contact area with the rice. The ribs 10 distributed on the baffle 9 can intercept again, which can not only delay the dispersion time of the rice, but also make the rice further disrupted and dispersed.

[0031] In this embodiment, the ribs 10 are in the shape of long strips, the ribs 10 protrude from the surface of the baffle 9, and the ribs 10 are inclined. The inclined ribs 10 can prevent the rice from sliding down directly from the baffle 9, extend the moving path of the rice, and shuffle and disperse the rice when pouring it. Due to gravity, the heavier rice falls first when the poured rice falls, and the lighter shells, dust and other debris fall and cover the rice later. The shells, dust and other debris mixed in the rice can be separated from the outer layer of the rice in advance, which is convenient for the debris to be directly separated after vibration screening, thereby reducing the screening time of the screening machine and effectively improving the screening efficiency of the screening machine.

[0032] In this embodiment, the centrifugal fan 12 and the first ash hopper 13 are respectively located on the left and right sides of the lower end of the feed hopper 6, the centrifugal fan 12 and the first ash hopper 13 are on the same axis, and the centrifugal fan 12 and the first ash hopper 13 are both connected to the screen frame 4. When feeding, the rotating baffle 9 can disturb and disperse the rice. When the dispersed and intercepted rice falls, the side centrifugal fan 12 blows air to one side of the first ash hopper 13, and the scattered shells, dust and other light debris can be blown laterally by the wind and blown into the first ash hopper 13, thereby reducing the shells, dust and other debris in the rice before screening, avoiding the accumulation of too much shells, dust and other debris in the rice to block the sieve holes, which can ensure the screening accuracy and extend the service life of the screen.
