Description

Technical Field

[0001] The invention relates to the technical field of rice processing, in particular to impurity removal equipment for rice production and processing. Background Art

[0002] During the rice transportation process in the pipeline, considering that the rice is easily accumulated at the bottom of the pipeline due to its own gravity, it is easy to cause blockage. At the same time, this transportation method is likely to cause the bottom of the pipeline to be worn by the rice for a long time, causing the pipeline to be easily damaged and reducing the service life of the equipment. At the same time, the rice is also easy to directly hit the inner wall of the elbow at the bend, causing the rice to break, resulting in an increase in the amount of broken rice, affecting the production quality of rice.

[0003] It is also taken into consideration that when the pipeline has been transporting rice for a long time, a large amount of impurities will easily accumulate on its inner wall. When impurities accumulate on the inner wall of the pipeline for a long time, they will easily deteriorate and contaminate the rice. In addition, since the pipeline is relatively long overall, it will be more difficult for workers to clean the pipeline. Summary of the invention

[0004] In order to overcome the disadvantages that the existing method of conveying rice is prone to blockage, and the rice is easily accumulated on one side of the pipeline under the influence of its own gravity, which accelerates the wear of the pipeline and makes it unusable, reducing the service life of the equipment, and at the same time, the pipeline is prone to accumulate impurities and pollute the rice when conveying rice for a long time, and it is too difficult for subsequent workers to clean the long conveying pipeline, the present invention provides an impurity removal equipment for rice production and processing.

[0005] The technical implementation scheme of the present invention is: an impurity removal device for rice production and processing, including a straight road and a curved pipe; the straight road is connected with a curved pipe on the left side; it also includes a rotating component, a first baffle, a second baffle and a cleaning system; a rotating component for reducing the wear of the inner wall of the straight road is arranged on the left side of the straight road; a plurality of first baffles are installed on the rotating component to prevent the straight road from being blocked; a plurality of second baffles are arranged on the rotating component; and a cleaning system for facilitating the removal of impurities is installed on the straight road.

[0006] Optionally, the rotating assembly includes a fixed plate, a servo motor, a rotating rod and a first sleeve; a fixed plate is fixedly connected to the left side of the curved tube; a servo motor is fixedly connected to the fixed plate; a rotating part of the servo motor is fixedly connected to the rotating rod, and the rotating rod passes through the curved tube; a first sleeve is fixedly connected to the rotating rod, the first sleeve is located inside the straight track, and the center point of the first sleeve is on the same horizontal line as the center point of the straight track; the first sleeve is fixedly connected to all first baffles.

[0007] Optionally, a buffer plate is also included; the inner side of the curved pipe is fixedly connected with the buffer plate to prevent rice from directly hitting the inner wall of the curved pipe, and the rotating rod passes through the buffer plate and is rotatably connected thereto.

[0008] Optionally, the right side surface of each first baffle is flush with the right side surface of the second baffle, and the distance between the left side surface of each first baffle and the fixed plate is smaller than the distance between the left side surface of the second baffle and the fixed plate.

[0009] Optionally, a plurality of protrusions are provided on the buffer plate to guide the rice to fall in sections; the protrusions are respectively provided on the front and rear sides of the buffer plate, and each protrusion is provided in an arc shape.

[0010] Optionally, the cleaning system includes an electric slider and an exhaust pipe; a plurality of slide grooves are opened on the upper side of the fixed plate; a plurality of electric sliders are slidably connected to the upper side of the fixed plate, and each electric slider slides in an adjacent slide groove; an exhaust pipe for cleaning the straight channel and impurities accumulated inside the bent pipe is connected to the left side of the bent pipe, and the exhaust pipe is connected to an external exhaust device.

[0011] Optionally, when the connection between the transfer rod and the first sleeve is not in use, a second sleeve is fixedly connected to the transfer rod, and the second sleeve is slidably connected to the first sleeve; a plurality of first air holes are opened on the first sleeve; and a plurality of second air holes are opened on the second sleeve.

[0012] Optionally, a buffer diaphragm is also included; the buffer diaphragm is fixedly connected to the inner side of the curved pipe to prevent the rice from directly rubbing against the inner wall of the curved pipe.

[0013] Optionally, each buffer diaphragm can be deformed and cooperate with each other to close the bent pipe.

[0014] Optionally, each of the first air holes and the second air holes is located between two adjacent first baffles.

[0015] The beneficial effects of the present invention are as follows: the present invention achieves the purpose of dispersing rice through two adjacent first baffles and two adjacent second baffles, thereby reducing the conveying pressure of rice accumulated in the straight channel, and avoiding the blockage caused by the rice being accumulated at the bottom of the inner side of the straight channel due to its own gravity;

[0016] The first baffle and the second baffle drive the rice to rotate and transport at the same time, so as to prevent the rice from only contacting the bottom of the inner side of the straight path, reduce the loss of the bottom of the inner side of the straight path, and extend the service life of the equipment;

[0017] By making each first baffle longer than the second baffle, the distance between two adjacent first baffles for conveying rice is longer, and the distance between two adjacent second baffles for conveying rice is shorter, thereby changing the initial outflow position of rice, thereby avoiding the phenomenon of mutual collision after rice flows out at the same time, and ensuring the integrity of rice after conveying;

[0018] When the air volume through the suction pipe is small, the dust and broken rice generated during the rice falling process are screened out. When the air volume through the suction pipe is large, the buffer diaphragm is closed to form a one-way airflow, thereby improving the cleaning ability of straight and curved pipes;

[0019] The suction force generated by the first air hole and the second air hole directly acts on the first baffle and the second baffle, and at the same time generates a stronger suction force to clean the first baffle and the second baffle, further improving the cleaning ability of the device for impurities.

DETAILED DESCRIPTION

[0028] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0029] Example 1

[0030] like Figure 1-Figure 5 As shown, a rice production and processing impurity removal device includes a straight channel 1 and a curved pipe 4; the straight channel 1 is connected to the curved pipe 4 on the left side;

[0031] It also includes a rotating assembly, a first baffle 2, a second baffle 5 and a cleaning system; a rotating assembly is arranged on the left side of the straight road 1; a plurality of first baffles 2 are installed on the rotating assembly; a plurality of second baffles 5 are arranged on the rotating assembly; and a cleaning system is installed on the straight road 1.

[0032] The rotating assembly includes a fixed plate 101, a servo motor 102, a rotating rod 103 and a first sleeve 104; the fixed plate 101 is fixedly connected to the left side of the curved tube 4; the servo motor 102 is fixedly connected to the fixed plate 101; the rotating part of the servo motor 102 is fixedly connected to the rotating rod 103, and the rotating rod 103 passes through the curved tube 4; the first sleeve 104 is fixedly connected to the rotating rod 103, the first sleeve 104 is located inside the straight track 1, and the center point of the first sleeve 104 is on the same horizontal line as the center point of the straight track 1; the first sleeve 104 is fixedly connected to all the first baffles 2.

[0033] The buffer plate 3 is also included; the buffer plate 3 is fixedly connected to the middle part of the inner side of the curved pipe 4, and the rotating rod 103 passes through the buffer plate 3 and is rotatably connected thereto.

[0034] The right side surface of each first baffle plate 2 is flush with the right side surface of the second baffle plate 5 , and the distance between the left side surface of each first baffle plate 2 and the fixing plate 101 is smaller than the distance between the left side surface of the second baffle plate 5 and the fixing plate 101 .

[0035] Two protrusions 3001 are arranged on the buffer plate 3; the protrusions 3001 are arranged on the front and rear sides of the buffer plate 3 respectively, and each protrusion 3001 is arranged in an arc shape.

[0036] In the process of conveying rice through the straight track 1, a plurality of first baffles 2 and second baffles 5 are arranged in the straight track 1, so that every two adjacent first baffles 2 and two adjacent second baffles 5 form a flow channel for conveying rice in the straight track 1. In the process of conveying rice, considering that the rice continues to rub against the inner wall of the straight track 1 during the flow process, the inner bottom of the straight track 1 is damaged by the friction of the rice for a long time, which greatly reduces the service life of the straight track 1. In order to avoid this phenomenon, the servo motor 102 is started to rotate clockwise based on the view from left to right, thereby driving the rotating rod 103 and the first sleeve 104 to rotate clockwise, so that the first baffle 2 and the second baffle 5 are in the first sleeve 104. The rice is first dispersed by two adjacent first baffles 2 and two adjacent second baffles 5, so as to reduce the conveying pressure of the rice accumulated in the straight road 1, and prevent the rice from being accumulated at the bottom of the inner side of the straight road 1 for conveying due to its own gravity. Meanwhile, during the rotation of the first baffle 2 and the second baffle 5, the rice is conveyed to the curved pipe 4 while rotating along the straight road 1 under the push of the first baffle 2 and the second baffle 5, so as to prevent the rice from contacting only with the bottom of the inner side of the straight road 1, reduce the wear on a single position of the inner side of the straight road 1, and extend the service life of the equipment. Meanwhile, the rice can be evenly dispersed in the straight road 1 for conveying, and the resistance caused by the accumulation of rice during the conveying process can be reduced.

[0037] It is also considered that when the rice is discharged from two adjacent first baffles 2 and two adjacent second baffles 5 to the curved pipe 4, in order to avoid the rice from gushing out at the same time and colliding with each other to form broken rice, the length of each first baffle 2 is longer than the second baffle 5, so that the distance between the two adjacent first baffles 2 for conveying the rice is longer, and the distance between the two adjacent second baffles 5 for conveying the rice is shorter, thereby changing the initial position of the rice gushing out, thereby avoiding the phenomenon of the rice gushing out at the same time and colliding with each other, and ensuring the integrity of the rice after conveying.

[0038] It is also considered that when the rice is discharged from the straight road 1 to the curved pipe 4, in order to prevent the rice from directly hitting the inner wall of the curved pipe 4 and being damaged, the buffer plate 3 is used to buffer and unload the rice, and at the same time reduce the speed of the rice, so that the rice can pass through the curved pipe 4 intact and finally be discharged from the lower side of the curved pipe 4. It should be noted that: in the initial state, all the first baffles 2 are close to the upper and lower quarter points of the straight road 1, and all the second baffles 5 are close to the front and rear quarter points of the straight road 1. In order to further prevent the rice from accumulating and colliding with each other when falling, as shown in FIG. Figure 2 As shown in FIG. 1 , since the distances of the rice conveyed from the two adjacent first baffles 2 and the two adjacent second baffles 5 are different, when the rice hits the middle of the buffer plate 3 for buffering, the rice adheres to the surface of the buffer plate 3 for buffering and then falls downward, and when the rice hits the protrusion 3001, as shown in FIG. Figure 5 As shown, since the raised portion 3001 is arranged in an arc shape, the rice flows along the arc surface of the raised portion 3001 toward the front and rear sides of the buffer plate 3 respectively, so that the rice flows in sections on the buffer plate 3 before falling downward, thereby preventing the rice from accumulating together again and colliding with each other, and further reducing the phenomenon of rice colliding with each other during the falling process.

[0039] Example 2

[0040] On the basis of Example 1, Figure 1 , Figure 6 and Figure 7 As shown, the cleaning system includes an electric slider 202 and an exhaust pipe 203; two slide grooves 10101 are opened on the upper side of the fixed plate 101; two electric sliders 202 are slidably connected to the upper side of the fixed plate 101, and each electric slider 202 slides in the adjacent slide grooves 10101; the exhaust pipe 203 is connected to the left side of the bent pipe 4, and the exhaust pipe 203 is connected to an external exhaust device.

[0041] Without using the connection relationship between the rotating rod 103 and the first sleeve 104 in Example 1, a second sleeve 204 is fixedly connected to the rotating rod 103, and the second sleeve 204 is slidably connected to the first sleeve 104; a plurality of first air holes 10401 are opened on the first sleeve 104; and a plurality of second air holes 20401 are opened on the second sleeve 204.

[0042] It also includes a buffer diaphragm 201 ; the buffer diaphragm 201 is fixedly connected to the inner side of the bent pipe 4 .

[0043] Each buffer diaphragm 201 can be deformed and cooperate with each other to close the elbow 4.

[0044] Each buffer membrane 201 is made of elastic rubber material to reduce the impact force when the rice falls and ensure the integrity of the rice.

[0045] Each of the first air holes 10401 and the second air holes 20401 is located between two adjacent first baffles 2 .

[0046] When the rice is discharged from the lower side of the curved pipe 4, a buffer membrane 201 is provided inside the curved pipe 4 to guide and buffer the freely falling rice, thereby first reducing the speed of the rice when it falls, and then guiding the rice to flow away from the inner wall of the curved pipe 4, thereby avoiding friction between the rice and the inner wall of the curved pipe 4 and ensuring the integrity of the rice.

[0047] It is also considered that after the straight road 1 and the curved pipe 4 have been used to transport rice for a long time, impurities are likely to accumulate inside the straight road 1 and the curved pipe 4, which will cause the impurities to deteriorate and easily contaminate the rice during transportation. Since the straight road 1 and the curved pipe 4 are relatively long as a whole, it is difficult for workers to clean them. At this time, the suction pipe 203 is evacuated by an external suction device, so that the impurities accumulated in the straight road 1 and the curved pipe 4 flow to the suction pipe 203 under the action of the air flow, and then the straight road 1 and the curved pipe 4 are cleaned. Furthermore, when the suction pipe 203 starts to evacuate air, the suction volume of the external suction device can be adjusted. When the suction volume is small, the suction volume can be adjusted. When the suction pipe 203 is used, the dust and broken rice generated in the process of rice falling can be screened away through the suction pipe 203, so as to avoid the spread of dust on the lower side of the curved pipe 4 and reduce the difficulty of rice screening in the later stage. When the suction volume of the suction pipe 203 is large, the straight road 1 and the curved pipe 4 are stopped from conveying rice, so that the buffer diaphragm 201 is bent and closed upward by the suction force of the suction pipe 203, thereby closing the lower side of the curved pipe 4. At this time, the outside air only enters from the right side of the straight road 1, so that the airflow flows from the right side of the straight road 1 to the curved pipe 4, forming a unidirectional airflow, thereby improving the cleaning ability of the straight road 1 and the curved pipe 4.

[0048] It is also taken into consideration that due to the provision of the first baffle plate 2 and the second baffle plate 5, impurities are easily accumulated and adhered to the first baffle plate 2 and the second baffle plate 5. Since each of the first air holes 10401 and the second air holes 20401 are located between two adjacent first baffle plates 2 and the second baffle plates 5, the suction force generated by the first air holes 10401 and the second air holes 20401 directly acts on the first baffle plates 2 and the second baffle plates 5. At the same time, the small-diameter first air holes 10401 and the second air holes 20401 generate stronger suction force under the same suction force, thereby improving the cleaning ability of the inner wall of the straight channel 1, and cleaning the first baffle plate 2 and the second baffle plate 5 at the same time, further improving the cleaning ability of the device for impurities.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
