Description

Technical Field

[0001] This utility model relates to the field of cylindrical pre-cleaning machine technology, and in particular to a cylindrical pre-cleaning machine for rice processing. Background Technology

[0002] A cylindrical primary cleaner is a primary cleaning device used in the processing of agricultural products such as grains and feed. It is mainly used to remove large impurities, light impurities, and dust from raw materials. When processing rice, a cylindrical primary cleaner is also needed to remove impurities from the rice.

[0003] For example, Chinese utility model patent application number CN202321763654.0 discloses a cylindrical primary cleaning machine for rice processing, including a machine body. A motor is fixedly installed on the machine body. The output end of the motor is fixedly connected to a rotating shaft extending into the machine body. A screen cylinder is fixedly connected to the rotating shaft. A feed pipe extending out of the machine body is fixedly connected to the screen cylinder. A telescopic rod is fixedly installed at the bottom of the machine body. A filter plate is fixedly installed on the telescopic rod. A first spring is welded between the filter plate and the bottom of the machine body. A discharge port corresponding to the filter plate is opened on the machine body. A collection chamber is opened at the lower end of the machine body. A drive mechanism for driving the filter plate to move up and down is provided in the machine body. The rotating shaft moves a force plate vertically downward through a cam. The force plate, in conjunction with the first spring and the second spring, enables the filter plate to move vertically up and down, and enables the filter plate to move vertically back and forth, which helps to improve the filtration effect of the filter plate.

[0004] Although the above-mentioned device can make the filter plate move vertically back and forth, improving the filtration effect of the filter plate, when the sieve cylinder is screening rice, some impurities are easily blocked in the sieve holes on the sieve cylinder, resulting in a decrease in the filtration efficiency and effect of the sieve cylinder on rice. Utility Model Content

[0005] This utility model discloses a cylindrical primary cleaning machine for rice processing, which solves the problem that some impurities easily clog the screen holes when the screen cylinder is screening rice.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A cylindrical pre-cleaning machine for rice processing includes a machine body with a screen cylinder inside. One end of the screen cylinder is connected to a feed pipe that penetrates the machine body. A motor for driving the screen cylinder to rotate is mounted on the machine body. The end of the screen cylinder away from the feed pipe is located below the other end and is open. A cover is fixed to the feed pipe to cover one end of the screen cylinder. A connecting plate is slidably connected to the inner wall of the cover. An insert rod that can be inserted into the screen hole of the screen cylinder is fixed on the connecting plate. A first spring is fixed between the connecting plate and the inner wall of the cover. A push rod penetrating the outer wall of the cover is fixed on the connecting plate. An arc-shaped plate is fixed above the cover inside the machine body. When the cover rotates, the arc-shaped plate pushes the end of the push rod downward so that the first spring is compressed and the insert rod enters the screen hole of the screen cylinder. A slag discharge port and a material discharge port are provided on the machine body.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] After the rice enters the screen cylinder through the feed pipe, the motor drives the screen cylinder to rotate and begin screening the rice. During the rotation of the screen cylinder, when the push rod approaches the arc plate, it will be gradually squeezed by the arc plate, and the first spring will be stretched, causing the push rod to push the connecting plate. The insert rod will then be inserted into the screen holes on the screen cylinder to clear the screen holes. This utility model can quickly clear the screen holes on the screen cylinder in real time, avoiding the situation where the screen holes are blocked and the screening efficiency and effect of rice decreases.

[0014] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a cylindrical primary cleaning machine for rice processing, including a machine body 1, a screen cylinder 2 inside the machine body 1, one end of the screen cylinder 2 being connected to a feed pipe 21 penetrating the machine body 1, a motor 3 for driving the screen cylinder 2 to rotate on the machine body 1, the end of the screen cylinder 2 away from the feed pipe 21 being located below the other end and being open; a cover 4 covering one end of the screen cylinder 2 is fixed on the feed pipe 21, a connecting plate 5 is slidably connected to the inner wall of the cover 4, an insert rod 51 that can be inserted into the screen hole of the screen cylinder 2 is fixed on the connecting plate 5, a first spring 52 is fixed between the connecting plate 5 and the inner wall of the cover 4, and a push rod 53 penetrating the outer wall of the cover 4 is fixed on the connecting plate 5; an arc-shaped plate 6 is fixed inside the machine body 1 above the cover 4, when the cover 4 rotates, the arc-shaped plate 6 is used to push the end of the push rod 53 downward so that the first spring 52 is compressed and the insert rod 51 enters the screen hole of the screen cylinder 2; the machine body 1 is provided with a slag discharge port and a material discharge port. The distance between the arc-shaped starting part of the bottom surface of the arc plate 6 and the outer ring surface of the cover 4 is greater than the distance between the end of the push rod 53 away from the insertion rod 51 and the outer ring surface of the cover 4. However, the distance between the lowest point of the arc plate part of the bottom surface of the arc plate 6 (the center of the bottom of the arc plate 6) and the outer ring surface of the cover 4 is less than the distance between the end of the push rod 53 away from the insertion rod 51 and the outer ring surface of the cover 4. The feed pipe 21 is rotatably connected to the machine body 1 through a bearing. The rice smoothly enters the inside of the screen cylinder 2 through the feed pipe 21. Then the motor 3 starts and drives the screen cylinder. 2. Rotation begins to finely filter the rice. During the rotation of the cover 4, once the push rod 53 contacts the arc surface of the bottom of the arc plate 6, it will gradually push the push rod 53, thereby causing the first spring 52 to stretch slowly. The connecting plate 5 drives the insertion rod 51 to move, so that the insertion rod 51 enters the sieve hole on the sieve cylinder 2 to clear the sieve hole and prevent impurities from clogging the sieve hole. The inner side of the cover 4 is provided with a group of connecting plates 5 arranged in a ring array. Each connecting plate 5 is equipped with a set of insertion rods 51. The sieve cylinder 2 is located inside these connecting plates 5.

[0016] like Figure 1 As shown, a rotating rod 31 that passes through the machine body 1 is fixed on the rotating shaft of the motor 3, and a fixed beam 22 that is fixed near the open part of the screen cylinder 2 and connected to the rotating rod 31 is fixed inside the screen cylinder 2.

[0017] like Figure 1 As shown, the feed port and slag discharge port on the machine body 1 are located on both sides of the machine body 1. Inside the machine body 1, there is a filter plate 7 with one side passing through the feed port of the machine body 1 and set at an inclination. A second spring 71 connected to the bottom inside the machine body 1 is fixed on the filter plate 7. A collection frame 8 with one side passing through the slag discharge port and located below the open part of the screen cylinder 2 is fixed on the top of the filter plate 7 through a support plate. A push plate 81 is fixed on the top of the collection frame 8. A cam 311 located above the push plate 81 is fixed on the rotating rod 31.

[0018] like Figure 1As shown, a sieve plate 82 is fixed inside the collection frame 8. The collection frame 8 is inclined, and a slag discharge pipe and a feed pipe are connected to the collection frame 8, located above and below the sieve plate 82, respectively. The motor 3 is fixed to the machine body 1 through a connecting seat. After the motor 3 is started, it can drive the rotating rod 31 to rotate through the rotating shaft, so that the fixed beam 22 drives the sieve cylinder 2 to start rotating. As the rotating rod 31 rotates, the cam 311 continuously drives the push plate 81, pushing the collection frame 8 to move up and down. This causes the filter plate 7 to reciprocate the lifting and lowering action by the elastic force of the second spring 71, thereby filtering the rice more effectively. The filtered rice is discharged through the feed port. The impurities discharged from the opening of the sieve cylinder 2 fall into the collection frame 8 and accumulate on the sieve plate 82. Thanks to the continuous up and down vibration of the collection frame 8, the rice in the impurities can be further screened. After the screened rice falls below the sieve plate 82, it is discharged through the feed pipe, while the impurities are discharged through the waste discharge pipe.

[0019] like Figure 1 and Figure 2 As shown, the diameter of the insertion rod 51 increases sequentially from one end near the screen cylinder 2 to the other end, and the diameter of the insertion rod 51 at the end near the screen cylinder 2 is smaller than the inner diameter of the screen hole on the screen cylinder 2.

[0020] like Figure 1 and Figure 2 As shown, a folding cylinder 54, which covers the first spring 52, is fixed between the connecting plate 5 and the inner wall of the cover 4. The end of the push rod 53 away from the connecting plate 5 is arc-shaped. The end of the insert rod 51 that first inserts into the sieve hole on the sieve cylinder 2 has a smaller diameter, so that it can enter the sieve hole more smoothly and clear the blockage of impurities. The folding cylinder 54 can protect the first spring 52. The inclination direction and angle of the arc plate 6 are the same as those of the sieve cylinder 2. When the arc-shaped end of the push rod 53 contacts the arc plate 6, the arc plate 6 can push the push rod 53 downward more smoothly.

[0021] like Figure 1 As shown, a guide plate 11 is fixed inside the body 1 on the side away from the collection frame 8, located between the sieve cylinder 2 and the filter plate 7. The side of the guide plate 11 closer to the collection frame 8 is lower than the other side.

[0022] like Figure 1 As shown, a waste discharge port is provided at the bottom of the machine body 1, and a storage frame 9 is placed between the two support legs at the bottom of the machine body 1. The inner diameter of the filter holes on the filter plate 7 is smaller than the inner diameter of the sieve holes on the sieve cylinder 2. After the rice falls onto the guide plate 11, it slides down the filter plate 7 to a position away from the discharge port, so that the rice has more time to slide down the filter plate 7 and better filters the dust in the rice; while the dust can be discharged into the storage frame 9 through the waste discharge port at the bottom of the machine body 1.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
