Description

Technical Field

[0001] This utility model relates to the technical field of vibrating screening devices, and in particular to a vibrating screening device for agricultural and sideline products. Background Technology

[0002] Against the backdrop of the rapid development of modern agriculture and food processing industries, the demand for efficient processing and refined grading of agricultural and sideline products is increasing. Agricultural and sideline products are diverse, ranging from granular agricultural products such as grains and beans to products of various shapes such as diced fruits and vegetables and fungi. Before entering the market circulation or deep processing stage, they all need to be screened to remove impurities and graded according to specifications.

[0003] However, in practical applications, agricultural products often contain sticky substances (such as sugar, starch, and soil), have high moisture content, or contain fibrous or flaky impurities (such as jujube peel, broken goji berries, and tea dust). These materials are easily stuck in the sieve holes or adhere to the sieve screen. Existing technologies cannot clean these materials that clog the filter screen in a timely manner during vibration. Frequent disassembly and cleaning will increase time costs. Cleaning can only be carried out when a large amount of blockage has accumulated on the filter screen, resulting in low cleaning efficiency of existing devices. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a vibrating screening device for agricultural and sideline products.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a vibrating screening device for agricultural and sideline products, comprising:

[0006] A base, on which a lower compartment is slidably connected, and on which an upper compartment is slidably connected;

[0007] The synchronous cleaning component includes a fixed frame fixedly connected to a base, a rubber frame fixedly connected to the fixed frame, a piston rod slidably connected to the rubber frame, a lifting rod fixedly connected to the piston rod, a cleaning plate fixedly connected to the lifting rod, sliding rods slidably connected to both sides of the rubber frame, sliding blocks fixedly connected to the sliding rods, transmission blocks fixedly connected to the sliding blocks, a transmission shaft slidably connected to the transmission blocks, a sliding plate fixedly connected to the transmission shaft, a lifting column slidably connected to the bottom of the sliding plate, a transmission frame fixedly connected to the lifting column, and a filter screen slidably connected to the transmission frame.

[0008] In a preferred embodiment, the cleaning plate is slidably connected to the filter screen, the lower compartment has an arc-shaped groove, the filter screen is slidably connected to the arc-shaped groove on the lower compartment, a motor is fixedly connected to the bottom of the filter screen, the side of the motor away from the base is fixedly connected to the base, and the motor is slidably connected to the lower compartment and the cleaning plate.

[0009] The above technical solution involves the transmission frame sliding on the filter screen near the base. When the cleaning plate presses against the transmission frame, it causes the transmission frame to slide down and rotate on the base. This causes the end of the transmission frame away from the lower compartment to lift the lifting column. The lifting column presses against the sliding plate, causing the sliding plate to lift the transmission shaft. The limiting rod limits the sliding plate to move vertically up and down. The transmission shaft slides in the inclined groove on the transmission block, causing the transmission block to be driven to move inward and clamp. A sealing ring is fixedly connected between the rubber frame and the sliding rod, causing the sliding rod to slide into the rubber frame. The air pressure inside the rubber frame increases, causing the piston rod to be lifted, which in turn lifts the lifting rod. The lifting rod then lifts the cleaning plate, inserting it into the filter screen to squeeze out impurities from the filter screen pores.

[0010] In a preferred embodiment, a damper is fixedly connected to the bottom of the lower compartment, and the side of the damper at the bottom of the lower compartment away from the lower compartment is fixedly connected to the base.

[0011] The above technical solution allows for a more flexible connection between the lower chamber and the base, reducing the force on the base when the filter screen in the lower chamber begins to rotate and screen under the action of release force.

[0012] In a preferred embodiment, a first rotating shaft is rotatably connected to the transmission frame, and the first rotating shaft is rotatably connected to the base.

[0013] The above technical solution is adopted: by setting a first rotating shaft, the transmission frame can be rotated on the base.

[0014] In a preferred embodiment, the base has an opening, and the lifting column is slidably connected to the opening on the base.

[0015] The above technical solution is adopted: by opening the base, the lifting column is not completely blocked, and the base does not carry materials, so there will be no material leakage.

[0016] In a preferred embodiment, the lower compartment is provided with a sliding hole, and the transmission frame is slidably connected to the sliding hole on the lower compartment.

[0017] The above technical solution is adopted: by setting a sliding hole on the lower compartment, the transmission frame can be driven to slide by the filter screen. In actual application, a spring is fixed in the opening. Two springs are set and fixed on the upper and lower sides of the transmission frame respectively. The side of the spring away from the transmission frame is fixed in the opening on the lower compartment, which can prevent the material from spilling out.

[0018] In a preferred embodiment, a limiting rod is fixedly connected to the base, and the sliding plate is slidably connected to the limiting rod.

[0019] The above technical solution is adopted: when in use, a limiting rod is fixedly connected to the base, and the sliding plate slides on the limiting rod, so that the sliding plate is limited to sliding only in the vertical direction.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] This invention utilizes the vibration and turbulence of the filter screen during the screening process to synchronously trigger the cleaning component's actions (such as the filter screen pressing the transmission frame, the transmission frame moving the lifting column to lift, the lifting column driving the sliding plate to lift, causing the transmission shaft to drive the transmission block to slide, causing the sliding rod to squeeze the rubber frame, causing the rubber frame to drive the piston rod to be lifted, so that the cleaning plate intermittently inserts into the screen, squeezing out the stuck material or adhered matter, avoiding the material clogging the screen holes due to stickiness, humidity or fiber characteristics as in the prior art. The cleaning process is carried out synchronously with screening, extending the cleaning cycle, solving the problem of needing to accumulate a large amount of blockage before stopping the machine for cleaning in the prior art, and significantly improving production continuity and efficiency.

[0032] 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.

[0033] like Figure 1-6 As shown, this utility model provides a technical solution: a vibrating screening device for agricultural and sideline products, comprising:

[0034] Base 1, with a lower compartment 11 slidably connected to the base 1, and an upper compartment 12 slidably connected to the base 1;

[0035] The synchronous cleaning component 2 includes a fixed frame 23 fixedly connected to the base 1, a rubber frame 212 fixedly connected to the fixed frame 23, a piston rod 214 slidably connected to the rubber frame 212, a lifting rod 215 fixedly connected to the piston rod 214, a cleaning plate 22 fixedly connected to the lifting rod 215, sliding rods 211 slidably connected to both sides of the rubber frame 212, sliding blocks 213 fixedly connected to the sliding rods 211, a transmission block 210 fixedly connected to the sliding blocks 213, a transmission shaft 29 slidably connected to the transmission block 210, a sliding plate 27 fixedly connected to the transmission shaft 29, a lifting column 26 slidably connected to the bottom of the sliding plate 27, a transmission frame 24 fixedly connected to the lifting column 26, and a filter screen 21 slidably connected to the transmission frame 24.

[0036] This invention utilizes the vibration and turbulence of the filter screen 21 during the screening process to synchronously trigger the action of the cleaning component (e.g., the filter screen 21 presses against the transmission frame 24, the transmission frame 24 moves the lifting column 26 to lift, the lifting column 26 drives the sliding plate 27 to lift, causing the transmission shaft 29 to drive the transmission block 210 to slide, which in turn drives the sliding rod 211 to squeeze the rubber frame 212, causing the rubber frame 212 to drive the piston rod 214 to be lifted, so that the cleaning plate 22 intermittently inserts into the screen to squeeze out the stuck material or adhering matter, avoiding the blockage of the screen holes by the material due to stickiness, humidity or fiber characteristics in the prior art. The cleaning process is carried out synchronously with screening, extending the cleaning cycle and solving the problem of needing to accumulate a large amount of blockage before stopping the machine for cleaning in the prior art, significantly improving production continuity and efficiency).

[0037] like Figures 1 to 5 As shown, the cleaning plate 22 is slidably connected to the filter screen 21. An arc-shaped groove is provided on the lower chamber 11. The filter screen 21 is slidably connected to the arc-shaped groove on the lower chamber 11. A motor 3 is fixedly connected to the bottom of the filter screen 21. The side of the motor 3 away from the base 1 is fixedly connected to the base 1. The motor 3 is slidably connected to the lower chamber 11 and the cleaning plate 22. The transmission frame 24 slides on the part of the filter screen 21 close to the base 1. When the cleaning plate 22 presses the transmission frame 24, the transmission frame 24 is driven to slide down and rotate on the base 1 by lever principle. The end of the transmission frame 24 away from the lower chamber 11 drives the lifting column 26 to lift. The lifting column 26 presses the sliding plate 27. The limiting action of the limiting rod 28 ensures that the sliding plate 27 rises and falls vertically. The transmission shaft 29 slides in the inclined groove on the transmission block 210, driving the transmission block 210 to move inward to clamp. The sealing ring between the rubber frame 212 and the sliding rod 211 prevents gas leakage. The sliding rod 211 slides into the rubber frame 212, which increases the internal air pressure, pushes the piston rod 214 to rise, and then drives the lifting rod 215 and the cleaning plate 22 to move upward, insert into the filter screen 21 filter hole, and quickly squeeze out the blockage impurities, so as to realize the simultaneous operation of screening and cleaning.

[0038] like Figures 1 to 5 As shown, a damper is fixedly connected to the bottom of the lower chamber 11. The side of the damper at the bottom of the lower chamber 11 away from the lower chamber 11 is fixedly connected to the base 1. The damper is set to provide a buffer between the lower chamber 11 and the base 1, so that the lower chamber 11 can move flexibly during the screening process. When the filter screen 21 rotates and screens under the action of centrifugal force, the damper effectively absorbs vibration energy, reduces the impact force on the base 1, reduces the wear and tear caused by vibration, extends the service life of the device, and at the same time avoids material splashing caused by violent vibration, ensuring a clean production environment and a stable screening process.

[0039] like Figures 3 to 5As shown, a first rotating shaft 25 is rotatably connected to the transmission frame 24. The first rotating shaft 25 is rotatably connected to the base 1. The first rotating shaft 25 provides a stable rotation fulcrum for the transmission frame 24, making the transmission frame 24 more flexible and smooth when rotating on the base 1. During the transmission process of the cleaning component, the first rotating shaft 25 ensures that the transmission frame 24 moves along a predetermined trajectory, avoiding jamming or deviation, and ensuring that the transmission frame 24 can drive the lifting column 26 and other components to move, providing reliable power transmission for the lifting and lowering of the cleaning plate 22, and improving the continuity and effectiveness of the cleaning action.

[0040] like Figures 1 to 4 As shown, the base 1 has an opening, and the lifting column 26 is slidably connected to the opening on the base 1. The opening on the base 1 provides room for the lifting column 26 to move, preventing it from being completely blocked by the base 1 during movement and affecting the transmission. Since the base 1 does not carry material, the opening design will not cause material leakage. This ensures the flexibility of the lifting column 26 transmission, maintains the sealing and cleanliness of the device, and ensures that the material is always within a controllable screening and cleaning area during the screening process.

[0041] like Figure 1 As shown, a sliding hole is provided on the lower compartment 11, and the transmission frame 24 is slidably connected in the sliding hole on the lower compartment 11. The sliding hole on the lower compartment 11 provides a guide and movement channel for the transmission frame 24, so that the transmission frame 24 can be driven to slide by the filter screen 21. In actual application, the spring fixed in the opening plays a buffering and resetting role. It can not only effectively prevent the material from spilling out of the opening, but also help the transmission frame 24 to quickly reset after completing the cleaning action, so as to prepare for the next cleaning cycle and improve the cleaning efficiency.

[0042] like Figures 4 to 6 As shown, a limiting rod 28 is fixedly connected to the base 1, and a sliding plate 27 is slidably connected to the limiting rod 28. The limiting rod 28 on the base 1 provides motion guidance for the sliding plate 27, limiting it to slide only in the vertical direction. During the transmission process of the cleaning component, this design effectively prevents the sliding plate 27 from shifting or shaking due to uneven force, ensuring that the sliding plate 27 drives the transmission shaft 29 to rise and fall stably, so that components such as the transmission block 210 and piston rod 214 can move according to the predetermined transmission logic, thereby ensuring that the cleaning plate 22 can be accurately inserted into the filter screen 21 for cleaning, and improving the stability and reliability of the entire cleaning process.

[0043] Working principle:

[0044] like Figure 1-6 As shown, when using it, first unscrew the bolts between the lower chamber 11 and the upper chamber 12, pour the material onto the filter screen 21, and then screw the upper chamber 12 back on.

[0045] The output end of motor 3 passes through cleaning plate 22 and lower chamber 11 base 1, and slides with cleaning plate 22 and lower chamber 11. It does not drive cleaning plate 22 and lower chamber 11 to move. When motor 3 starts, it drives filter screen 21 to rotate. Filter screen 21 slides in arc groove on lower chamber 11. The speed of motor 3 gets faster and faster, which makes filter screen 21 drive the material to bounce and screen the material.

[0046] At this time, the filter screen 21 will press the transmission frame 24 at intervals under the guidance of the arc groove, causing the transmission frame 24 to rotate and push the lifting column 26 to rise. The lifting column 26 will drive the sliding plate 27 to rise, and the sliding plate 27 will drive the transmission shaft 29 to slide in the inclined hole on the transmission block 210. At this time, the transmission block 210 will drive the sliding rod 211 to slide on the rubber frame 212, causing the rubber frame 212 to undergo elastic deformation, squeezing out the piston rod 214. The piston rod 214 will drive the lifting rod 215 to rise, and the lifting rod 215 will drive the cleaning plate 22 to rise, so that the cleaning plate 22 will intermittently insert into the filter screen 21 to squeeze out the material stuck in the filter screen 21.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
