Description

Technical Field

[0001] The present application relates to the technical field of excrement cleaning for rice screening, and in particular to a detection device for a rice screening machine. Background Art

[0002] After the rice has been husked and other processes have been completed, there is still a lot of "bad rice" in the rice. The definition of bad rice is often made by judging the color of the rice. In order to ensure the overall quality of the rice when it is bagged, the rice with poor color needs to be removed, thereby improving the final overall quality of the bagged rice.

[0003] The process of removing rice with poor color is the color sorting process. The color sorting method is often used: the rice slides down the channel. In order to improve the color sorting efficiency, the channel is often set in a vertical manner to the ground. The rice accelerates to slide down under the action of gravity to achieve a faster color sorting process. During the transmission of rice, the rice will be superimposed on the conveyor belt. During the accumulation of rice, good rice will be mixed with bad rice, making the distance between good rice and bad rice closer, causing the air gun to blow out good rice when removing bad rice, affecting the accuracy of screening. Therefore, those skilled in the art provide a rice screening machine detection device to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the present application provides a rice screening machine detection device.

[0005] The rice screening machine detection device provided in this application adopts the following technical solution:

[0006] A rice screening machine detection device comprises a conveyor belt, mounting plates are arranged on both sides of the conveyor belt, a smoothing component is arranged on one side of one of the mounting plates, and the smoothing component is arranged above the conveyor belt;

[0007] A guide block is arranged on one side of the conveyor belt, a pressure plate is arranged above the guide block, a baffle is fixedly connected to one side of the pressure plate, a connecting plate is arranged below the guide block, a color sorting module and a spray gun are arranged inside the connecting plate, and the color sorting module is arranged above the spray gun;

[0008] The guide plate is arranged on the baffle plate and is located at a side away from the spray gun.

[0009] In some embodiments, a side of the guide plate away from the connecting plate is inclined downward.

[0010] In some embodiments, a plurality of guide blocks are provided, and the plurality of guide blocks are attached to the surfaces of the conveyor belt and the connecting plate.

[0011] In some embodiments, a limiting groove is provided on one side of the mounting plate, and a plurality of limiting grooves are provided. The smoothing component includes a fixed block located inside the limiting groove, a fixing rod is inserted into the inside of the fixing block, a scraper is fixedly connected to the surface of the fixing rod, and the scraper is horizontally placed above the conveyor belt.

[0012] In some embodiments, a connection block is fixedly connected above the scraper, and a plurality of connection ropes are provided above the connection blocks.

[0013] In some embodiments, an extrusion block is fixedly connected to the bottom of the scraper, and a plurality of the extrusion blocks are arranged at equal intervals, and the bottoms of the plurality of extrusion blocks are in contact with the surface of the conveyor belt.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] (1) Workers pour rice onto the conveyor belt, which moves the rice. When the rice moves on the conveyor belt, the smoothing component smoothes the piled rice so that the rice is flattened on the surface of the conveyor belt to reduce the accumulation of rice. During the transmission on the conveyor belt surface, the rice enters the inside of the guide block. The guide block is fixed by the upper pressure plate and the baffles and connecting plates on both sides to increase stability. The rice falls under the guidance of the guide block. During the falling process, the rice passes through the color sorting module and the spray gun. The color sorting module selects bad rice by color. The spray gun blows the bad rice out through the gap of the baffle. The blown bad rice is guided by the guide plate and falls into the bad rice box. This design smoothes the rice on the surface of the conveyor belt through the smoothing component, reduces the accumulation of rice, and increases the distance between the rice and the bad rice when the rice falls inside the guide block, thereby increasing the screening efficiency.

[0016] (2) There is a gap between the guide block and the conveyor belt, which facilitates the rotation of the conveyor belt under the guide block. The guide block separates the rice on the surface of the conveyor belt, so that the rice is divided into multiple conveyor lines. Multiple conveyor lines are directly opposite to the outlet of the spray gun, so that the rice passes through the color sorting module and the spray gun accurately, which increases the accuracy of the spray gun blowing on bad rice and reduces missed selection and screening.

[0017] (3) The bottom of the multiple extrusion blocks is in contact with the surface of the conveyor belt. The extrusion blocks are arc-shaped and are in contact with the bottom of the scraper. The multiple extrusion blocks level the rice and guide the rice so that the rice is divided into multiple strips and moves on the surface of the conveyor belt, thereby increasing the spacing between the rice and reducing the accumulation of rice, which is convenient for subsequent screening.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-5 This application is described in further detail.

[0025] The present application embodiment discloses a rice screening machine detection device. Figure 1-5 A rice screening machine detection device comprises a conveyor belt 1, a guide block 4 and a guide plate 8, mounting plates 2 are arranged on both sides of the conveyor belt 1, a smoothing component 3 is arranged on one side of one mounting plate 2, the smoothing component 3 is arranged above the conveyor belt 1, the guide block 4 is arranged on one side of the conveyor belt 1, a pressing plate 5 is arranged above the guide block 4, a baffle 6 is fixedly connected to one side of the pressing plate 5, a connecting plate 7 is arranged below the guide block 4, a color sorting module 71 and a spray gun 72 are arranged inside the connecting plate 7, the color sorting module 71 is arranged above the spray gun 72, and the guide plate 8 is arranged on the baffle 6 and is located on a side away from the spray gun 72;

[0026] In this way, during the implementation process, when it is necessary to screen the rice, the worker pours the rice on the top of the conveyor belt 1, and the conveyor belt 1 will move the rice. When the rice is located above the conveyor belt 1 and moves, the smoothing component 3 will smooth the piled rice, so that the rice is flattened on the surface of the conveyor belt 1 to reduce the accumulation of rice. The rice will enter the interior of the guide block 4 during the transmission on the surface of the conveyor belt 1. The guide block 4 is fixed with the baffles 6 and the connecting plate 7 on both sides through the upper pressing plate 5 to increase stability. The rice falls under the guidance of the guide block 4. The rice will pass through the color sorting module 71 and the spray gun 72 during the falling process. The color sorting module 71 will screen out bad rice by color. The spray gun 72 blows out the bad rice through the gap of the baffle 6. The blown bad rice is guided by the guide plate 8 to fall into the bad rice box. This design smoothes the rice on the surface of the conveyor belt 1 through the smoothing component 3, reduces the accumulation of rice, and increases the distance between the rice and the bad rice when the rice falls inside the guide block 4, thereby increasing the screening efficiency.

[0027] Among them, the guide plate 8 is tilted downward on the side away from the connecting plate 7, and the guide plate 8 is installed on the baffle 6. The guide plate 8 is located below the notch of the baffle 6. The guide plate 8 guides downward to guide the bad rice. The bad rice slides on the surface of the guide plate 8, so that the bad rice is away from the good rice, which facilitates the screening of the rice.

[0028] Preferably, a plurality of guide blocks 4 are provided, and the plurality of guide blocks 4 are attached to the surfaces of the conveyor belt 1 and the connecting plate 7. The guide blocks 4 are equidistantly placed on the surface of the conveyor belt 1. A gap exists between the guide blocks 4 and the conveyor belt 1, so that the conveyor belt 1 is conveniently located below the guide blocks 4 and rotates. The guide blocks 4 separate the rice on the surface of the conveyor belt 1, so that the rice is divided into a plurality of conveyor lines, and the plurality of conveyor lines are directly opposite to the outlet of the spray gun 72, so that the rice accurately passes through the color sorting module 71 and the spray gun 72, so that the blowing accuracy of the spray gun 72 on bad rice is increased, and missed selection and screening are reduced.

[0029] Specifically, a limiting groove 21 is provided on one side of the mounting plate 2, and a plurality of limiting grooves 21 are provided. The smoothing assembly 3 includes a fixing block 31 located inside the limiting groove 21, a fixing rod 32 is inserted inside the fixing block 31, and a scraper 33 is fixedly connected to the surface of the fixing rod 32, and the scraper 33 is horizontally placed above the conveyor belt 1;

[0030] The limiting groove 21 will limit the smoothing component 3, and the smoothing component 3 is located on the surface of the mounting plate 2 and slides, which is convenient for adjusting the height of the fixing block 31. The fixing block 31 fixes the fixing rod 32 and the scraper 33. The fixing rod 32 is driven to rotate by rotating the fixing rod 32, which is convenient for adjusting the angle of the fixing rod 32. One end of the fixing rod 32 passes through the mounting plate 2 and is threadedly connected to the nut, and the nut fixes the fixing rod 32 above the mounting plate 2.

[0031] More specifically, a connecting block 35 is fixedly connected above the scraper 33, and a connecting rope 36 is provided above the multiple connecting blocks 35. The multiple connecting blocks 35 are fixed to the connecting rope 36. The connecting rope 36 enables the multiple scrapers 33 to rotate synchronously, so that the rotation angles of the multiple scrapers 33 are consistent, which facilitates the adjustment of the scrapers 33.

[0032] Furthermore, during the implementation process, a squeezing block 34 is fixedly connected to the bottom of the scraper 33. A plurality of squeezing blocks 34 are equidistantly arranged. The bottoms of the plurality of squeezing blocks 34 are in contact with the surface of the conveyor belt 1. The squeezing blocks 34 are arc-shaped and are in contact with the bottom of the scraper 33. The plurality of squeezing blocks 34 level the rice and guide the rice so that the rice is divided into a plurality of strips and moves on the surface of the conveyor belt 1, thereby increasing the spacing between the rice, reducing the accumulation of rice, and facilitating subsequent screening.

[0033] The implementation principle of the detection device of a rice screening machine in the embodiment of the present application is as follows: when the rice needs to be screened, the worker pours the rice onto the conveyor belt 1, and the conveyor belt 1 moves the rice. When the rice is located above the conveyor belt 1 and moves, the smoothing component 3 smoothes the piled rice so that the rice is spread on the surface of the conveyor belt 1 to reduce the accumulation of rice. During the transmission process on the surface of the conveyor belt 1, the rice enters the interior of the guide block 4, and the guide block 4 is fixed by the upper pressure plate 5 and the baffles 6 and connecting plates 7 on both sides. The rice falls under the guidance of the guide block 4. The rice passes through the color sorting module 71 and the spray gun 72 during the falling process. The color sorting module 71 selects bad rice by color. The spray gun 72 blows the bad rice out through the gap of the baffle 6. The blown bad rice is guided by the guide plate 8 and falls into the bad rice box. This design smoothes the rice on the surface of the conveyor belt 1 through the smoothing component 3, reduces the accumulation of rice, and increases the distance between the rice and the bad rice when the rice falls inside the guide block 4, thereby increasing the screening efficiency.
