Description

Technical Field

[0001] This utility model relates to the field of rice screening technology, specifically a vibrating screening machine for rice screening. Background Technology

[0002] The rice vibrating screen uses the excitation force generated by a vibrating motor to cause the screen body to vibrate at high frequency. Under this vibration, the rice grains jump and move rapidly on the screen surface, thereby separating broken rice and other impurities, ensuring the quality of the rice.

[0003] Currently, some vibrating screens work by having broken rice fall off as the rice jumps and moves across the screen. However, the stroke of some vibrating screens is relatively limited, and during the screening process, broken rice may not be completely screened out while rice is discharged. As a result, workers need to repeatedly feed, screen, collect, and feed the rice. This process is not only labor-intensive, but also causes rice to spill out and be wasted during manual collection and handling. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating screening machine for rice screening, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screener for rice screening, comprising an outer frame, a vibrating device body installed at the bottom of the outer frame, a screen installed inside the outer frame, and a first discharge port and a second discharge port located at the bottom of the outer frame, and further comprising:

[0006] Side plate one and side plate two are fixedly connected to the surface of the outer frame. A fixing box is fixedly connected to the surface of side plate one, and a horizontal plate is fixedly connected to the surface of side plate two. A guide mechanism and a pressing mechanism are installed on the surface of the fixing box, and a positioning plate is installed at the bottom of the pressing mechanism.

[0007] A feeding frame is fixedly connected to the surface of the outer frame. One end of the feeding frame is fixedly connected to an infeed frame, and the other end of the feeding frame is connected to a fixed box. The bottom sides of the inner wall of the fixed box and the bottom of the inner wall of the feeding frame are inclined. A feeding mechanism is installed on the top of the horizontal plate.

[0008] Preferably, the guiding mechanism includes a rotating shaft, a guide plate, and a rotating plate. The rotating shaft rotatably passes through the surface of the fixed box, and one end of the rotating shaft is rotatably connected to the inner wall of the fixed box. The rotating plate is fixedly connected to the other end of the rotating shaft, and the guide plate is fixedly sleeved on the surface of the rotating shaft. The surface of the guide plate is in contact with the inner wall of the fixed box, and the surface of the positioning plate is in contact with the surface of the rotating plate.

[0009] Preferably, the pressing mechanism includes a storage frame, a pressing plate, a compression spring, and an extension plate. The storage frame is fixedly connected to the surface of the fixed box, the surface of the pressing plate is slidably connected to the inner wall of the storage frame, the compression spring is disposed inside the storage frame, the extension plate is fixedly connected to the surface of the pressing plate, and the positioning plate is fixedly connected to the bottom of the pressing plate.

[0010] Preferably, the feeding mechanism includes a cylinder, a drive rod, a spiral blade, and a starter motor. The cylinder is fixedly inserted through the top of the horizontal plate. The drive rod rotatably inserts through the top of the cylinder and is rotatably connected to the bottom of the inner wall of the cylinder. The spiral blade is fixedly sleeved on the surface of the drive rod. The motor is fixedly connected to the top of the cylinder. The top of the drive rod is fixedly connected to the output shaft of the cylinder. The feed frame is fixedly inserted through the surface of the cylinder.

[0011] Preferably, a discharge plate is fixedly inserted through the surface of the cylinder, and one end of the discharge plate extends into the interior of the outer frame.

[0012] Preferably, both sides of the inner wall of the fixed box are fixedly connected to limit plates, the surface of the limit plates is provided with arc-shaped grooves, and the surface of the guide plate is in contact with the inner wall of the arc-shaped grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, the operator can adjust the state of the guiding mechanism according to the discharge situation at the discharge port. When there is still broken rice being discharged from the discharge port, the guiding mechanism can guide the rice into the inside of the conveying frame so that the feeding mechanism can re-feed the rice and repeat the rice screening operation. When there is no broken rice being discharged from the discharge port, the operator can first release the limit on the rotating plate, and then drive the guide plate to rotate through the rotating plate and the rotating shaft so that the guide plate can assist the screened rice to be discharged to the outside for the operator to collect. This solves the problem that the efficiency of single rice screening is not good when some vibrating screening machines are used. The repeated feeding, screening and collection operations are not only laborious for the operator, but also prone to rice spillage during the process. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6As shown, a vibrating screener for rice screening includes an outer frame 1, a vibrating device body 2 installed at the bottom of the outer frame 1, a screen 3 installed inside the outer frame 1, and a first discharge port 4 and a second discharge port 5 located at the bottom of the outer frame 1. The outer frame 1, the vibrating device body 2, the screen 3, the first discharge port 4, and the second discharge port 5 work together to form the vibrating screener. The use of the vibrating screener is a mature existing technology. Rice is poured onto the screen 3, which drives the top of the screen. The vibrating device body 2 drives the outer frame 1 and the screen 3 to vibrate, thereby screening out broken rice and other contaminants from the rice. The screened rice is discharged through the second discharge port 5, and the screened broken rice and other contaminants are discharged through the first discharge port 4. The outer frame 1... The surface of the frame is fixedly connected to side plate 16 and side plate 214. Side plate 16 is fixedly connected to a fixed box 7. Side plate 214 is fixedly connected to a horizontal plate 15. The surface of the fixed box 7 is equipped with a guide mechanism 8 and a pressing mechanism 10. The bottom of the pressing mechanism 10 is equipped with a positioning plate 11. The positioning plate 11 is used to restrict the position of the guide mechanism 8. The guide mechanism 8 is adjusted inside the fixed box 7 to adjust the feeding direction of the rice. The surface of the outer frame 1 is fixedly connected to a feeding frame 12. The top of the horizontal plate 15 is equipped with a feeding mechanism 16. One end of the feeding frame 12 is fixedly connected to an inlet frame 13. The other end of the feeding frame 12 is connected to the fixed box 7.

[0024] It is worth noting that the technical features proposed in this technical solution, such as the vibrating device body 2, the screen 3, and the discharge port 4, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0025] The guiding mechanism 8 includes a rotating shaft 81, a guide plate 82, and a rotating plate 83. The rotating shaft 81 rotates through the surface of the fixed box 7. One end of the rotating shaft 81 is rotatably connected to the inner wall of the fixed box 7. The rotating plate 83 is fixedly connected to the other end of the rotating shaft 81. The guide plate 82 is fixedly sleeved on the surface of the rotating shaft 81. The surface of the guide plate 82 is in contact with the inner wall of the fixed box 7. Limiting plates 9 are fixedly connected to both sides of the inner wall of the fixed box 7. The surface of the limiting plate 9 is provided with an arc-shaped groove. The surface of the guide plate 82 is in contact with the inner wall of the arc-shaped groove. The setting of the limiting plate 9 can support the guide plate 82. The bottom sides of the inner wall of the fixed box 7 and the bottom of the inner wall of the feeding frame 12 are inclined. The side of the bottom of the inner wall of the feeding frame 12 near the fixed box 7 is higher than the side of the bottom of the inner wall of the feeding frame 12 near the feeding frame 13, so as to facilitate the feeding of rice. The surface of the positioning plate 11 is in contact with the surface of the rotating plate 83.

[0026] By setting the guide mechanism 8, when the guide plate 82 is in a certain state... Figure 4As shown, rice falls from the discharge port 25 into the fixed box 7, and the guide plate 82 guides the rice into the inside of the conveying frame 12 so that the rice can be re-screened.

[0027] The pressing mechanism 10 includes a storage frame 101, a pressing plate 102, a compression spring 103, and an extension plate 104. The storage frame 101 is fixedly connected to the surface of the fixed box 7. The surface of the pressing plate 102 is slidably connected to the inner wall of the storage frame 101. The compression spring 103 is disposed inside the storage frame 101. The two ends of the compression spring 103 are fixedly connected to the top of the inner wall of the storage frame 101 and the top of the pressing plate 102, respectively. The extension plate 104 is fixedly connected to the surface of the pressing plate 102 and slidably connected to the inner wall of the storage frame 101. The positioning plate 11 is fixedly connected to the bottom of the pressing plate 102. When the operator lifts the extension plate 104, the pressing plate 102 can be moved upward. At this time, the compression spring 103 is compressed, and the positioning plate 11 is lifted with the pressing plate 102. The contact between the positioning plate 11 and the rotating plate 83 is released. Then, under the action of the elastic force of the compression spring 103, the positioning plate 11 descends and presses down on the rotating plate 83 again to limit the position of the rotating plate 83.

[0028] The feeding mechanism 16 includes a cylinder 161, a drive rod 162, and a spiral blade 163. The cylinder 161 is fixedly inserted through the top of the horizontal plate 15. The drive rod 162 rotates through the top of the cylinder 161 and is rotatably connected to the bottom of the inner wall of the cylinder 161. The spiral blade 163 is fixedly sleeved on the surface of the drive rod 162. A motor 164 is fixedly connected to the top of the cylinder 161. The top of the drive rod 162 is fixedly connected to the output shaft of the cylinder 161. The feed frame 13 is fixedly inserted through the surface of the cylinder 161. The rice inside the feed frame 12 is conveyed to the inside of the cylinder 161 through the feed frame 13. When the operator starts the motor 164, the drive rod 162 can be driven to rotate. The drive rod 162 then drives the spiral blade 163 to rotate, thus conveying the rice inside the cylinder 161.

[0029] A discharge plate 17 is fixedly inserted through the surface of the cylinder 161. One end of the discharge plate 17 extends into the interior of the outer frame 1. By setting the discharge plate 17, the rice conveyed upward by the feeding mechanism 16 can be discharged back into the interior of the outer frame 1 for screening again.

[0030] Working principle: The operator pours rice onto the screen 3 inside the outer frame 1 and starts the vibrating device body 2 and motor 164. The vibrating screen 3 can screen the rice. Broken rice and other particles are discharged through the first discharge port 4. The rice enters the fixed box 7 through the second discharge port 5. Guided by the guide plate 82, the rice enters the conveying frame 12 and is discharged into the cylinder 161 through the feed frame 13. When the motor 164 drives the drive rod 162 to rotate, the spiral blades 163 rotate accordingly, which can convey the rice in the cylinder 161 upwards. After being discharged through the discharge plate 17, the rice is re-discharged into the inner frame 1. This allows for repeated screening of the rice to ensure the screening effect. When no broken rice is discharged from the lower discharge port 4, the worker can pull the extension plate 104 and lift the lower pressure plate 102. The positioning plate 11 is then lifted, and the limit on the rotating plate 83 is released. At this time, the worker can rotate the guide plate 82 through the rotating plate 83 and the rotating shaft 81 to adjust the direction of subsequent rice discharge. After that, the screened rice can be directly discharged through the fixed box 7, and the worker can collect the screened rice.
