Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in figures 1 and 2, the rice grain separating device of the utility model comprises a frame 1, a screen frame 2 and a vibrating motor 3. The rice outlet end and the tail end of the screen frame 1 are respectively provided with a supporting spring 4, the lower end of each supporting spring 4 is connected with the rack 1, and therefore the supporting springs 4 are mounted on the rack 1 in a suspended mode. Frame 1 with be equipped with between supporting spring 4 with first cushion 11, first cushion 11 upper end with supporting spring 4 lower extreme is connected, with 2 tail ends of reel supporting spring 4 corresponds first cushion 11 lower extreme is equipped with the lift adjusting screw 12 of adjusting this first cushion height, and lift adjusting screw 12 and frame threaded connection, the upper end is connected with first cushion 11 lower extreme. The lower end of the first rubber mat 11 corresponding to the supporting spring 4 at the rice outlet end of the screen frame 1 is fixedly connected with the frame 1; be equipped with one-level screen cloth 21 in the reel 2, shock dynamo 3 installs on reel 2.

For further screening, the utility model provides a still be equipped with the second grade screen cloth 22 that the mesh is less than one-level screen cloth 21 mesh in reel 2, second grade screen cloth 22 sets up in one-level screen cloth 21 below.

The rice grain separating device can be installed at a rice outlet of a rice mill when in use. During operation starts shock dynamo 3, and shock dynamo 3 drives the vibrations of reel 2, because reel 2 is through supporting spring 4 unsettled installation in frame 1, and be equipped with between frame 1 and the supporting spring 4 with first cushion 11, so, under the dual cushioning effect of supporting spring 4 and first cushion 11, frame 1 can not produce vibrations almost to noise pollution has been reduced. The rice that drops on one-level screen cloth 21 is constantly sieved at 2 vibrations in-process of reel, and tiny whole rice, garrulous rice and half garrulous rice in the rice drop to second grade screen cloth 22 on, through the screening of second grade screen cloth 22 again, garrulous rice drops on the reel bottom plate. Finally, the screened rice, small whole rice and broken rice respectively flow out from a first-stage rice outlet 25, a second-stage rice outlet 26 and a broken rice outlet 27 at the rice outlet end (lower end) of the chute 2 under the action of gravity. When needs adjustment goes out rice velocity of flow, the accessible is adjusted lift adjusting screw 12 and will be with the first cushion 11 jack-up and the decline that the supporting spring 4 of reel 1 tail end corresponds to the gradient of reel 2 is adjusted to the certain extent, changes the velocity of flow of rice, and then the adjustment screening effect.

The lower end of the first rubber cushion 11 and the frame 1 can be fixedly connected by conventional connection modes such as bolt connection, clamping connection and the like, and the bolt connection is adopted in the figure. First cushion 11 upper end and 4 lower extremes of supporting spring are connected and also can adopt bolted connection, the embodiment of the utility model provides an in first cushion 11 upper end be equipped with the first recess 111 of 4 external diameter adaptations of supporting spring, the supporting spring 4 lower extreme is inserted and is established in first recess 111 to be connected with first cushion 11. So, compare bolted connection, above-mentioned mode supporting spring installs more conveniently, and is movable being connected between supporting spring and the first cushion 11, can further the shock attenuation, and the installation of reel 2 is dismantled more conveniently to conveniently change the spring and the screen cloth is changed to the reel.

Reel 2 and supporting spring 4 can lug connection, the embodiment of the utility model provides an in, be equipped with second cushion 23 between reel 2 and the supporting spring 4, second cushion 23 upper end and reel 2 rigid coupling, the lower extreme be equipped with the second recess 231 of 4 external diameter adaptations of supporting spring, supporting spring 4 upper end is inserted and is established in second recess 231 to be connected with reel 2 through second cushion 23, can further increase the shock attenuation effect like this, noise abatement pollutes, also makes things convenient for supporting spring's installation, change.

Because the unsettled setting of reel 2 can shake, the operator touches the reel easily when rice processing, and this not only can disturb the reel vibrations and can also take place to hinder the people accident, for this reason, the utility model discloses a 2 both sides of reel are equipped with guard plate 13, and guard plate 13 is connected with frame 1. It will be appreciated that a certain distance between the screening sheet 13 and the frame is required in order not to disturb the vibrations of the frame.

The utility model discloses in, there is one-level screen cloth 21 top to be equipped with the current-limiting baffle 24 of adjusting out rice flow, and 24 one ends of current-limiting baffle are connected with the reel lateral wall, and one end is connected with reel opposite side lateral wall to install in

reel

2, 24 height-adjustable settings of current-limiting baffle. Through the height of adjustment current-limiting baffle 24, the distance between adjustment current-limiting baffle 24 and the one-level screen cloth 21 can be adjusted out rice flow, also can make the rice can with evenly distributed on one-level screen cloth 21, so, can guarantee the screening quality better.

The height-adjustable setting of the flow-limiting baffle 24 is realized by the following way: the flow-limiting baffle plate 24 is connected with the screen frame through bolts, and bolt holes in the flow-limiting baffle plate 24 are arranged to be vertically extending strip-shaped holes.

The existing rice grain separating device is usually screened in a left-right swinging mode, the screening cards are easy to be screened in the mode, and the screening effect of the rice grain separating device can be influenced along with the increase of the screening cards. In order to solve the problem, the utility model discloses in, shock dynamo 3 is horizontal shock dynamo, and shock dynamo 3 installs in 2 bottoms of reel, and 3 pivots of shock dynamo turn to 2 play rice directions to the reel. 3 pivots of shock dynamo turn to 2 play rice directions of reel, promptly: the rotating shaft of the vibrating motor 3 points to the width direction of the screen frame 2 (the rice outlet direction of the screen frame is the length direction). Set up back reel 2 like this and be vibrations from top to bottom, the difficult card of rice is on the screen cloth, guarantees that reel rice sieve permanent result of use is stable.

In order to facilitate the installation of the rice grain separating device on the rice mill, the frame 1 is provided with a bolt connecting hole 15.

The utility model also provides a rice mill, including the rice mill main part, rice mill main part rice outlet below is equipped with foretell grain of rice separator. After this rice mill adopted above-mentioned grain of rice separator, grain of rice separator's vibrations can not transmit to the rice mill main part, and whole rice mill noise is little, and lift adjusting screw 12 will be with the first cushion 11 jack-ups and the decline that the supporting spring 4 of reel 1 tail end corresponds to be adjusted to the accessible to the gradient of adjusting reel 2 in the certain limit, the velocity of flow that changes the rice, and then the adjustment screening effect.
