DETAILED DESCRIPTION

[0041] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present application.

When an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0043] Please refer to Figures 1-11 In the embodiments of the present application, a rice dust removal treatment device with intermittent transposition and top feeding, comprising: a support 1, a fixed plate 2, a storage tank 3, a supporting plate 25, a feeding hopper 11, a dust removal assembly, a driving mechanism, a lifting feeding mechanism and a Maltese cross movement core assembly and a centrifugal control assembly, the present application can remove dust from rice under the action of centrifugal force and the dust removal assembly, avoiding the problems of rice moisture and rice quantity loss caused by washing and blowing. When in use, the rice to be dusted is placed in the storage tank 3. At this time, the driving mechanism works and drives the lifting feeding mechanism to move through the Maltese cross movement core assembly, so that the rice in the storage tank 3 is conveyed to the feeding hopper 11 through the lifting feeding mechanism. At the same time, the driving mechanism also drives the feeding hopper 11 to rotate. Under the action of centrifugal force, the rice moves away from the feeding hopper 11. In the feeding process of the lifting feeding mechanism, the centrifugal control assembly is also driven to move, and the speed of the feeding hopper 11 is increased by the driving mechanism, so that the movement stroke of the rice increases, until the rice moves to the cooperation position of the dust removal assembly. Under the action of the dust removal assembly, the rice is dusted. When the dusting is completed, the lifting feeding mechanism moves towards the storage tank 3 again. At the same time, the lifting feeding mechanism also drives the centrifugal control assembly to move, and the speed of the feeding hopper 11 is reduced by the driving mechanism, so that the centrifugal force acting on the rice in the dust removal assembly is reduced. At this time, under the action of gravity, the rice is separated from the dust removal assembly. The above steps are repeated, so as to realize the effect of continuous dust removal of the rice in the storage tank 3.

[0044] Specifically, it includes:

[0045] The support 1 is fixedly installed with symmetrically arranged fixed plates 2, and the support 1 is also fixed with a storage tank 3 for storing rice to be treated, and the fixed plate 2 is fixed with a supporting plate 25;

[0046] Please refer to Figures 1-3 、 Figures 5-7 , the feeding hopper 11 is arranged on the support 1, the fixed plate 2 is provided with a dust removal assembly connected with the feeding hopper 11 and the storage tank 3, the dust removal assembly comprises a partition plate 12 fixedly installed on the side wall of the feeding hopper 11, a filter hopper 10 is fixed on the side wall of the partition plate 12, and a limiting ring 9 is fixed on the filter hopper 10; the dust removal assembly further comprises a supporting ring 8 fixedly installed on the fixed plate 2 and in sliding connection with the limiting ring 9, and the storage tank 3 is rotatably installed with symmetrical cleaning rollers 7 at the bottom.

[0047] In detail, the feeding hopper 11 is arranged in a conical shape, the filter hopper 10 can be divided into three parts, the first part is arranged in a columnar shape and located at the same horizontal plane as the partition plate 12, the second part is arranged in a conical shape and has an inclination angle greater than that of the feeding hopper 11, and the third part is also arranged in a columnar shape and has a size greater than that of the first part, and the second part and the third part are both provided with sieve holes to allow smaller impurities to pass through, and a gap is left between the partition plate 12 and the first part of the filter hopper 10, when rice needs to be processed, the feeding hopper 11 and the filter hopper 10 are driven to rotate under the action of the driving mechanism, so that the rice in the feeding hopper 11 is subjected to a certain centrifugal force and moves towards the direction away from the rotation center of the feeding hopper 11, as the rotation speed of the feeding hopper 11 increases, the centrifugal force acting on the rice in the feeding hopper 11 gradually increases, until the rice separates from the feeding hopper 11 and passes through the gap between the partition plate 12 and the first part of the filter hopper 10, at this time, the rice falls on the second part of the filter hopper 10 in a parabolic shape, since the filter hopper 10 is also rotating, the rice is subjected to a centrifugal force again and moves along the conical surface of the second part of the filter hopper 10 towards the third part of the filter hopper 10, until the rice adheres to the third part of the filter hopper 10 due to the centrifugal force, under the action of the centrifugal force, part of the impurities adhering to the rice will separate from the rice and be discharged through the sieve holes, since the filter hopper 10 is continuously rotating, when the rice in the filter hopper 10 moves to the position adhering to the cleaning roller 7, the rice is subjected to a dust removal treatment under the action of the cleaning roller 7, when the dust removal is completed, at this time, the driving mechanism controls the rotation speed of the feeding hopper 11 to decrease, so that the rotation speed of the filter hopper 10 decreases, when the centrifugal force acting on the rice is less than the gravity acting on the rice, the rice will separate from the filter hopper 10 and be discharged through the gap between the first part of the filter hopper 10 and the partition plate 12, at this time, the untreated rice can be transported into the feeding hopper 10 again for dust removal treatment.

[0048] Preferably, by changing the centrifugal force, the position of the rice placed in the feeding hopper 11 can be changed, and the rice can be controlled to move to the position cooperating with the dust removal assembly, after the dust removal is completed, the rice can also be controlled to automatically separate from the dust removal assembly by the centrifugal force, so that the effect of continuously removing dust from the rice is achieved.

[0049] Please refer to Figures 1-5 、 Figure 8 , the fixed plate 2 is further provided with a driving mechanism connected with the feeding hopper 11, the driving mechanism can drive the feeding hopper 11 to rotate, and control the rice in the feeding hopper 11 to swing into the dust removal assembly, the driving mechanism can also drive the dust removal assembly to carry out dust removal treatment on the rice through the feeding hopper 11, the driving mechanism comprises a motor 20 fixedly installed on the fixed plate 2, a transmission rod 21 connected with the output shaft of the motor 20 is rotatably installed on the fixed plate 2, a second belt 26 is sleeved on the transmission rod 21, a driven assembly connected with the second belt 26 is arranged on the support 1, the driven assembly is connected with the feeding hopper 11 and the centrifugal control assembly, the driven assembly is also connected with the lifting feeding mechanism, the transmission rod 21 is connected with the Malta cross movement core assembly, wherein the driven assembly comprises a rotating sleeve 13 fixedly installed at the bottom of the feeding hopper 11, a rotating disc 27 is fixed on the rotating sleeve 13, a plurality of sliding grooves 28 distributed at equal intervals in a circle are formed in the rotating disc 27; the driven assembly further comprises a sliding rod 29 slidingly installed in the sliding groove 28, an arc-shaped plate 30 is fixed at the end of the sliding rod 29 away from the sliding groove 28, the arc-shaped plate 30 is connected with the second belt 26, the sliding rod 29 is connected with the centrifugal control assembly, and the rotating sleeve 13 is connected with the lifting feeding mechanism.

[0050] It should be noted that the first belt 22 can be stretched or contracted to a certain extent, in the initial state, the feeding hopper 11 is not filled with rice, at this time, the sliding rod 29 is located at the end of the stroke away from the sliding groove 28, so that the spacing between the arc-shaped plates 30 is maximum, the first belt 22 is in a stretched state, at this time, the motor 20 works to drive the transmission rod 21 to rotate, thereby driving the first belt 22 to move, the first belt 22 also drives the arc-shaped plate 30 to move, and drives the sliding rod 29 to move, so that the rotating disc 27 provided with the sliding groove 28 moves, and the rotating disc 27 also drives the rotating sleeve 13 to rotate, thereby driving the feeding hopper 11 to rotate, the feeding hopper 11 also drives the filter hopper 10 to move through the partition plate 12, so that the limiting ring 9 rotates in the supporting ring 8, the transmission rod 21 also drives the Malta cross movement core assembly to move, and controls the lifting feeding mechanism to move, so that the rice in the storage tank 3 is conveyed into the feeding hopper 11 through the lifting feeding mechanism.

[0051] Preferably, the lifting feeding mechanism also drives the centrifugal regulating assembly to move during the conveying of rice, so that the sliding rod 29 continuously moves towards the chute 28, and the arc-shaped plate 30 moves towards each other. At this time, the first belt 22 will be contracted, and the rotating speed of the rotating disc 27 will be continuously increased, so that the rotating speed of the feeding hopper 11 is increased, and therefore, when the rice falls into the feeding hopper 11, the centrifugal force received by the rice is also continuously increased. Until the lifting feeding mechanism completes the conveying and moves to the end of the stroke, the rotating speed of the feeding hopper 11 and the filtering hopper 10 reaches the maximum, at this time, the rice completely enters the filtering hopper 10, and when the lifting feeding mechanism moves towards the storage tank 3, the sliding rod 29 moves away from the chute 28 under the action of the centrifugal regulating assembly. At this time, the second belt 26 is stretched again, and the rotating speed of the rotating disc 27 is reduced, so that the centrifugal force received by the rice is reduced, until the gravity of the rice is greater than the centrifugal force, and the rice will be separated from the filtering hopper 10.
