Description
Technical Field
[0001] This utility model relates to the field of white rice processing technology, and in particular to an adjustable guide plate for white rice grading sieves. Background Technology
[0002] In the white rice processing technology, the grading screen is a key piece of equipment used to grade the white rice according to the integrity of the grains. There are many types of grading equipment, among which the linear vibrating screen is often used in this process because of its high efficiency and large processing capacity. The material vibrates and moves forward on the screen surface and is finally discharged through the discharge guide plate at the end.
[0003] However, the existing linear vibrating screen has a fixed discharge guide plate structure at the end, which only has a simple guiding function. Since white rice of different qualities and particle sizes needs to flow out at an appropriate speed after screening, if the discharge speed is too fast, the white rice will leave the screen body too quickly, which will lead to inaccurate grading. Conversely, if the discharge speed is too slow, the efficiency will be greatly reduced. Therefore, we propose an adjustable guide plate for white rice grading screen to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable guide plate for white rice grading sieves.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable guide plate for grading white rice includes a discharge guide plate, which is bolted to the front end of a screen frame. A support strip is provided on the side of the discharge guide plate away from the screen frame, and a limit block is fixedly connected to the inner side of the support strip. A T-shaped limit strip is inserted inside the limit block and is fixedly connected to the side of a lifting plate. A limit rod is inserted at the center of the support strip, and a rotating block is fixedly connected to the end of the limit rod. Limiting holes that match the limit rod are equidistantly opened on the side of the lifting plate.
[0006] Preferably, the two ends of the support bar abut against the docking plate, and the inner side of the docking plate is fixedly connected to the end of the discharge guide plate. The interior of the docking plate is connected to the support bar by bolts.
[0007] Preferably, the inner side of the lifting plate is provided with a buffer pad, and the buffer pad is configured with a U-shaped structure.
[0008] Preferably, the side of the buffer pad is fixedly connected to a mounting plate, and the inner side of the mounting plate is symmetrically connected to a plug rod. The inside of the lifting plate is provided with a snap-fit groove that matches the plug rod.
[0009] Preferably, the outer wall of the plug rod is equidistantly connected with rubber rings, and the outer wall of the rubber rings and the inner wall of the snap-fit groove are in close contact.
[0010] Preferably, there are two sets of the limiting blocks and T-shaped limiting strips, and the two sets of the limiting blocks and T-shaped limiting strips are symmetrically distributed about the central axis of the support strip.
[0011] Preferably, the outer wall of the rotating block is bonded with a rubber sleeve, and the outer wall of the rubber sleeve is uniformly provided with anti-slip texture.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device is equipped with support bars and a lifting plate. During use, the lifting plate, which can be raised and lowered, can precisely control the discharge speed of white rice. This not only allows the white rice to be fully screened and separated on the screen surface, improving the purity and quality of the rice, but also increases the screening efficiency of the white rice.
[0013] 2. This device is equipped with a buffer pad and a connecting rod. During use, the rubber buffer pad protects the inside of the lifting plate to ensure the service life of the lifting plate. The buffer pad and connecting rod can be used to replace the buffer pad when it reaches the end of its service life. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-5 An adjustable guide plate for grading white rice includes a discharge guide plate 1, which is bolted to the front end of a screen frame 2 and mounted above a linear vibrating screen support. The specific principle of grading and screening white rice is existing technology and will not be elaborated upon here. A support strip 3 is provided on the side of the discharge guide plate 1 away from the screen frame 2, and a limiting block 4 is fixedly connected to the inner side of the support strip 3. A T-shaped limiting strip 5 is inserted inside the limiting block 4 and is fixedly connected to the side of a lifting plate 6. A limiting rod 7 is inserted at the center of the support strip 3, and a rotating block 8 is fixedly connected to the end of the limiting rod 7. Limiting holes 9, matching the limiting rod 7, are equidistantly opened on the side of the lifting plate 6. External threads are opened on the outer surface of the limiting rod 7, and a threaded groove matching the limiting rod 7 is opened at the center of the support strip 3, thus ensuring the limiting effect of the limiting rod 7 on the lifting plate 6.
[0018] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the two ends of the support bar 3 abut against the docking plate 10 respectively, and the inner side of the docking plate 10 is fixedly connected to the end of the discharge guide plate 1. The inside of the docking plate 10 is connected to the support bar 3 by bolts. The end of the support bar 3 is provided with screw holes that are compatible with the bolts. During use, the support bar 3 can be easily disassembled from the front side of the discharge guide plate 1 by the cooperation of the docking plate 10 and the bolts for maintenance and repair.
[0019] Furthermore, refer to Figure 3 , Figure 4 and Figure 5 It can be seen that the inner side of the lifting plate 6 is provided with a buffer pad 11, and the buffer pad 11 is set with a U-shaped structure. During use, the buffer pad 11 set with the U-shaped structure can cover and protect the lifting plate 6, thereby effectively ensuring the service life of the lifting plate 6.
[0020] Furthermore, refer to Figure 3 and Figure 5 It can be seen that the side of the buffer pad 11 is fixedly connected to the mounting plate 12, and the inner side of the mounting plate 12 is symmetrically connected to the plug rod 13. The inside of the lifting plate 6 is provided with a snap-fit groove that matches the plug rod 13. During use, the buffer pad 11 that has reached the end of its service life can be disassembled and replaced by the cooperation of the mounting plate 12, the plug rod 13 and the snap-fit groove, which can effectively reduce the maintenance cost of this device.
[0021] Furthermore, refer to Figure 3It can be seen that the outer wall of the plug rod 13 is equidistantly connected with rubber rings 14, and the outer wall of the rubber rings 14 and the inner wall of the snap-fit groove are tightly abutted. During use, the rubber rings 14 with multiple rubber materials can effectively ensure the tightness of the plug rod 13 being snapped into the snap-fit groove.
[0022] Furthermore, refer to Figure 3 It can be seen that there are two sets of limit blocks 4 and T-shaped limit bars 5, and the two sets of limit blocks 4 and T-shaped limit bars 5 are symmetrically distributed about the central axis of the support bar 3. By setting two sets of limit blocks 4 and T-shaped limit bars 5, the stability of the lifting plate 6 when it moves up and down can be effectively guaranteed.
[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the outer wall of the rotating block 8 is glued with a rubber sleeve, and the outer wall of the rubber sleeve is evenly provided with anti-slip texture. The rubber sleeve and anti-slip texture are not shown in the figure. Through the cooperation of the two, the rotating block 8 can be rotated conveniently and effortlessly by the staff.
[0024] Working Principle: In use, the operator first installs the discharge guide plate 1 on the front side of the screen frame 2 with bolts. Then, the operator pours the rice that needs to be graded into the screen frame 2. Through the vibration motor on the screen frame 2 and the screen inside it, the rice can be graded. Before sieving, the operator can manually rotate the rotating block 8 according to the type of rice, so that the limiting rod 7 connected to the inner side of the rotating block 8 can rotate simultaneously, thereby pulling the limiting rod 7 out of the limiting hole 9. Then, the operator can pull the lifting plate 6 to a suitable height, so that there is a suitable gap between the top of the lifting plate 6 and the bottom wall of the discharge guide plate 1. Then, the operator can rotate the rotating block 8 in the opposite direction, so that the limiting rod 7 connected to its inner side can be inserted back into the corresponding limiting hole 9 inside the lifting plate 6, thereby limiting the lifting plate 6 again. Through the setting of the lifting plate 6, the discharge speed of the rice can be controlled. The above is the complete working principle of this utility model.
