Detailed Description

As shown in fig. 1-5, a rice scale cleaning device comprises an inner screen drum 1 and an outer screen drum 2. Wherein, an interior sieve section of thick bamboo 1 includes solid pipe portion 1.1, screening portion 1.2, installs passive belt pulley 1.3 on the solid pipe portion 1.1, and passive belt pulley 1.3 is used for follow-up synchronous belt drive interior sieve section of thick bamboo 1 rotation of sheatheeing in. The sieving part 1.2 is formed by a plurality of connecting rods which are evenly distributed at intervals in the circumferential direction, and the interval gap is larger than the size of broken rice and smaller than the size of complete rice, so that broken rice grains and other small particle impurities (mainly ash) can fall conveniently. The welding of screening portion 1.2 both ends is at mounting bracket 1.4, and the welding of mounting bracket 1.4 outer lane has an outer screen section of thick bamboo 2, and an outer screen section of thick bamboo 2 is the drum structure, is covered with the through-hole on the drum, and the through-hole size is less than the broken rice size, makes things convenient for broken grain of rice to keep somewhere like this in an outer screen section of thick bamboo 2, and other small particle impurity (mainly be the ash) fall down. The guide rails are arranged in the front and the back of the outer side of the outer screen drum 2, the front and the back groups (four in each group) of rollers 3 are uniformly distributed and are in contact with the guide rails, and the rollers 3 play a role in supporting the outer screen drum 2. The roller 3 can be directly a bearing, the inner ring of the bearing is welded with the bracket 6 through a short shaft, the left side and the right side of the bracket 6 are fixed on the dust deposition groove 7 through bolts, and the dust deposition groove 7 is positioned under the outer screen cylinder 2. The lower part of the ash deposition groove 7 is connected with the supporting legs, and the supporting legs are fixed on the ground.

A support (not shown in the figure) is arranged below one side of the solid pipe part 1.1, a driving belt pulley and a motor 5 are installed on the support, the driving belt pulley, a driven belt pulley 1.3 and a belt form a belt conveying mechanism 4, and the belt conveying mechanism 4 is driven to rotate by the motor 5 so as to drive the inner screen drum 1 and the outer screen drum 2 to rotate.

In order to accelerate the discharging, the inner screen cylinder 1 and the outer screen cylinder 2 are both arranged obliquely downwards, and the lower end of the inner screen cylinder is directed to the discharging hole of the inner screen cylinder 1. For convenient separation business turn over material, both ends all surpass a section of distance in outer screen section of thick bamboo 2 about the inner screen section of thick bamboo 1 here, and later stage detachable connects the material. The dust-collecting groove 7 is composed of a left half circular groove and a right half circular groove which incline downwards towards the middle and are provided with dust outlets in the middle.

During operation, a sieve section of thick bamboo 1, an outer sieve section of thick bamboo 2 rotate in the motor 5 drives, and the rice is followed solid pipe portion 1.1 and is got into sieve branch portion 1.2, and at the in-process through sieve branch portion 1.2, broken rice or granule impurity pass through sieve branch portion 1.2 the clearance enter into an outer sieve section of thick bamboo 2, and rotatory in-process in an outer sieve section of thick bamboo 2, granule impurity (mainly be the dust) falls in the deposition groove 7 through the hole of an outer sieve section of thick bamboo 2. Because the inner screen drum 1 and the outer screen drum 2 are obliquely arranged, the rice qualified by the coarse screen flows out through the outlet of the inner screen drum 1, and the broken rice flows out from the outlet of the outer screen drum 2.

In addition, in order to control the ordered feeding of rice, a chute 8 is installed at the feeding end of the inner screen cylinder 1, and the other end of the chute 8 is connected with a rice discharging hopper 9. The rice discharge hopper 9 comprises a rice storage bin 9.1, and the rice storage bin 9.1 can be used for loading through manual loading or be connected with a preorder device. The discharge gate and the discharge bin 9.2 of storing up rice bin 9.1 lower extreme are connected, install the axle in the discharge bin 9.2, and the axle stretches out one end and is connected with dividing material motor 9.4, and the part circumference that the axle is located discharge bin 9.2 is fixed with a plurality of branch flitchs 9.3, divides flitch 9.3 to divide into a plurality of interval regions with discharge bin 9.2 inner space. The rice can be orderly and uniformly discharged by driving the shaft through the material distributing motor 9.4 and driving the material distributing plate 9.3 to rotate at a certain speed.
