Description

Technical Field

[0001] The invention relates to the field of grain processing equipment, and in particular to a double-drum environmentally friendly cleaning screen for grain storage. Background Art

[0002] The cleaning screen is a commonly used device in grain storage. It is mainly used to clean impurities, foreign matter or harmful substances in grain to ensure the quality and safety of grain. It usually has high sorting efficiency and cleaning effect, which is very important in grain processing, storage and transportation. However, due to the lack of a reasonable screening structure, the grain screening is not thorough, and there are still grains or impurities with smaller particle sizes.

[0003] In view of the above problems, the existing patent provides a graded grain cleaning screen (publication number: CN221908155U). The technical solution uses a limit plate and a screen mesh in combination, and the screening path is longer, the screening time is guaranteed, and the grain screening is more sufficient. At the same time, the use of a material-dividing device can ensure that the grain will not be piled up and the grain feeding is uniform.

[0004] However, in actual use of the above scheme, since grain particles vary in size and are prone to agglomeration, agglomerated grains are prone to block the screen holes during screening, resulting in inadequate subsequent screening and affecting grain storage.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] See also Figure 1 - Figure 4 As shown, this embodiment is a double-drum environmentally friendly cleaning screen for grain storage, including a cylinder 1 and a cylinder 2, the cylinder 1 is movably mounted on one side of the cylinder 2, a box 4 is movably mounted on the top of the cylinder 1, a filter plate 401 is fixedly mounted in the box 4, a screen cylinder 201 is movably mounted in the cylinder 2, and a spiral fan blade is movably mounted inside the cylinder 1, and the spiral fan blade is fixedly mounted on the rotating rod 301.

[0032] The spiral fan blades are located below the filter plate 401. In actual use, after the grain particles are filtered by the filter plate 401, they fall into the cylinder 1. When the rotating rod 301 rotates, the grain is pushed into the cylinder 2 by the rotating spiral fan blades. When the spiral fan blades come into contact with the grain, the agglomerated grain is squeezed to separate it, thereby reducing the subsequent processing pressure and effectively improving the subsequent screening effect.

[0033] A motor is fixedly installed on one side of the cylinder 2, and the output end of the motor is fixedly connected to the rotating rod 301. A plurality of through holes are provided on the inner wall of the sieve cylinder 201. The sieve cylinder 201 is fixedly connected to the rotating rod 301 through a connecting rod 315. A plurality of connecting rods 315 are provided, and the connecting rods 315 are evenly spaced on the rotating rod 301. The motor is used to drive the rotating rod 301 to rotate. When the rotating rod 301 rotates, the connecting rod 315 is used to drive the sieve cylinder 201 to rotate synchronously. A discharge port is provided at the bottom of the cylinder 2.

[0034] During the rotation of the sieve drum 201, grain particles fall into the cylinder body 2 through the through hole of the sieve drum 201 and move to the discharge port under the action of gravity. A guide plate is fixedly installed at the discharge port. A slag discharge port is provided on the side of the cylinder body 2 away from the cylinder body 1. The slag discharge port is located below the rotating rod 301. As the sieve drum 201 rotates, impurities remaining in the sieve drum 201 are gradually discharged from the slag discharge port. Through holes are provided on the filter plate 401 and the sieve drum 201, which are not drawn in the figure.

[0035] A cleaning assembly 3 is fixedly installed in the cylinder 1 and the cylinder 2, and the cleaning assembly 3 includes a rotating rod 301, a movable plate 302 and a movable rod 303. The rotating rod 301 is movably installed in the cylinder 1 and the cylinder 2, and one end of the rotating rod 301 passes through the cylinder 1 and is fixedly connected with a cam 304. The movable plate 302 is fixedly installed at one end of the box 4, and the movable plate 302 is located above the cam 304. During the rotation of the rotating rod 301, the cam 304 rotates synchronously therewith. When the small diameter end of the cam 304 is upward, it will squeeze the movable plate 302, and under the action of the movable plate 302, it will push the box 4 to move.

[0036] The moving rod 303 is movably installed on the top of the cylinder body 1, the top of the moving rod 303 is fixedly connected to the box body 4, a fixed tube 308 is fixedly installed on the top of the cylinder body 1, the moving rod 303 is movably installed in the fixed tube 308, a spring is fixedly installed at the bottom of the moving rod 303, one end of the spring is fixedly connected to the inner wall of the fixed tube 308, a plurality of fixed tubes 308 are provided, and the fixed tubes 308 are evenly spaced at the top of the cylinder body 1.

[0037] When the box body 4 moves upward, the moving rod 303 moves upward synchronously, and the spring is gradually stretched. After the cam 304 is separated from the moving plate 302, the box body 4 is reset under the action of gravity and the spring, and the cam 304 continues to rotate, thereby driving the box body 4 to swing up and down, so that the grain particles on the filter plate 401 are more evenly distributed, thereby improving the screening efficiency of the filter plate 401;

[0038] That is, firstly, the grain to be stored is put into the box body 4, and the large-volume foreign matter in the grain is removed by using the filter plate 401. The removed grain enters the cylinder body 1, and at this time, the rotating rod 301 rotates to push the grain in the cylinder body 1 into the cylinder body 2, and the cylinder body 2 is used to finely screen the grain to remove the small-volume foreign matter in the grain. That is, through multi-stage screening, on the one hand, the working pressure of the cylinder body 2 is reduced, and on the other hand, large-volume foreign matter is prevented from clogging the inside of the cylinder body 2, thereby effectively improving the grain screening efficiency and screening effect.

[0039] Embodiment 2:

[0040] See also Figure 5 - Figure 6 As shown, the present invention also includes airbag 1 305, airbag 2 306 and impact block 307. Airbag 1 305 is fixedly installed above the box 4, airbag 2 306 is fixedly installed on the top of cylinder 2, impact block 307 is movably installed inside cylinder 2, the top of impact block 307 is fixedly connected to airbag 2 306, and airbag 1 305 is fixedly connected to airbag 2 306 through a pipeline.

[0041] A connecting plate 309 is fixedly installed on the top of the cylinder body 2, and a fixed tube 310 is fixedly installed on the connecting plate 309. A push rod 311 is movably installed in the fixed tube 310. The bottom of the push rod 311 is against the top of the box body 4, that is, when the box body 4 reciprocates up and down, the push rod 311 is driven to move. An extrusion block 312 is fixedly installed on the top of the push rod 311.

[0042] When the push rod 311 moves, the extrusion block 312 moves synchronously therewith, and the top of the extrusion block 312 is fixedly connected to the airbag 1 305. When the extrusion block 312 moves upward, the airbag 1 305 is squeezed. A spring is sleeved on the push rod 311, and the two ends of the spring are respectively fixedly connected to the extrusion block 312 and the inner wall of the fixed tube 2 310. When the box body 4 moves downward, the push rod 311 is reset under the action of the spring.

[0043] A fixed tube three 313 is fixedly installed on the top of the cylinder body 2, the impact block 307 is movably installed in the fixed tube three 313, the airbag 2 306 is fixedly installed in the fixed tube three 313, and a reset block 314 is fixedly installed at one end of the impact block 307. A spring is sleeved on the impact block 307, and both ends of the spring are fixedly connected to the reset block 314 and the fixed tube three 313 respectively.

[0044] When the extrusion block 312 squeezes the airbag 1 305, the gas in the airbag 1 305 moves to the airbag 2 306 through the pipeline, thereby driving the airbag 2 306 to expand, and the expanded airbag 2 306 drives the impact block 307 to move downward until it collides with the screen cylinder 201. At this time, the spring on the impact block 307 is gradually compressed. When the extrusion block 312 is reset, the impact block 307 is reset under the action of the spring. At this time, the reset block 314 squeezes the airbag 2 306, and the gas in the airbag 2 306 flows back to the airbag 1 305 to achieve circulation.

[0045] That is, when the rotating rod 301 rotates, the movable plate 302 is periodically lifted by the cam 304, thereby driving the box body 4 to make a vertical reciprocating motion on the top of the cylinder body 1. During the movement, the box body 4 is used to squeeze the airbag 1 305. At this time, the gas in the airbag 1 305 flows into the airbag 2 306. The periodically expanded airbag 2 306 drives the impact block 307 to collide with the screen drum 201, and then the vibration is used to make the blockage on the screen drum 201 fall off, effectively preventing the screen drum 201 from being blocked and affecting the grain screening.

[0046] In combination with Example 1 and Example 2, the cam 304 and the movable plate 302 cooperate to make the cylinder 1, the cylinder 2 2 and the box 4 cooperate with each other, while improving the screening efficiency of the box 4 and reducing the subsequent working pressure, the impact block 307 is driven to periodically impact the screen cylinder 201, thereby cleaning the screen cylinder 201, effectively avoiding the blockage of the screen cylinder 201 and affecting the grain screening, and the rotating rod 301 is used to drive the rotating blades and the screen cylinder 201 to rotate, not only using the rotating blades to process the agglomerated grain, but also performing multi-stage screening on the grain to ensure the quality of the processed grain.
