Description

A sorting machine drum with adjustable hole depth Technical Field

[0001] This utility model relates to the field of seed cleaning technology, specifically a cleaning machine drum with adjustable seed hole depth. Background Technology

[0002] A grain separator, also known as a sieving machine or screening machine, is used to remove impurities from grains. The screening drum is a widely used material sorting device in agriculture, mining, and food processing. Its core function is to screen and separate materials of different sizes or shapes through the perforated structure on the drum surface. Traditional screening drums typically use a fixed perforation design with non-adjustable perforation depth, resulting in poor adaptability to different material characteristics (such as particle size, shape, and moisture content). For example, in agricultural seed sorting, different seed varieties may require different perforation depths to achieve optimal sorting results. Traditional equipment often requires replacing the entire drum or screen, which is not only cumbersome to operate but also increases production costs and time consumption.

[0003] Existing screening equipment cannot achieve automatic switching between multiple rollers when materials need to be screened in series. For example, when multi-stage sorting of materials is required, traditional equipment usually requires manual intervention to reconfigure the roller arrangement or adjust the material conveying path, which seriously affects production efficiency and automation.

[0004] When production demands change (such as switching from fine sorting to coarse screening), existing equipment struggles to quickly switch between independent single-drum operation and multi-drum coordinated operation. Specifically, when single-drum operation is required, the separation of the two drums cannot be effectively controlled, leading to unnecessary energy consumption and wear. When multi-drum operation is required, precise docking between the drums cannot be ensured, affecting the continuous screening effect of materials.

[0005] Traditional equipment lacks the ability to simultaneously sort and collect particles of different sizes: when multiple rollers work together, the size of the holes in each roller is fixed and cannot be dynamically adjusted according to the characteristics of the material; the material collection system after sorting is not optimized, which makes it easy for particles of different specifications to be mixed, requiring subsequent manual secondary sorting. Summary of the Invention

[0006] Purpose of the utility model: To provide a cleaning machine roller with adjustable hole depth to solve the above-mentioned problems existing in the prior art.

[0007] Technical solution: A sorting machine roller with adjustable hole depth, comprising:

[0008] The container includes a housing, a perforated roller disposed within the housing, and a receiving chamber disposed within the perforated roller. The perforated roller comprises a fixed roller and a movable roller. A feeding pipe is provided on one side of the receiving chamber, and a screw rod is provided inside the feeding pipe and the receiving chamber.

[0009] Two sprockets are provided at their relative positions to drive each other. The two ends of the sprockets inside the movable roller are movably connected to the chamber through bearings. An external toothed ring is fitted onto the outer wall of the eyelet roller. The external toothed ring meshes with the output gear of the first motor located outside the chamber. A storage chamber installed inside the chamber is provided at the joint of the two eyelet rollers. A sleeve is provided on one side of the movable roller, which is fitted onto the sprocket and extends out of the chamber. The sleeve is fixedly connected to the movable roller. Multiple discharge baffles are provided inside the chamber. The discharge baffles are located at the discharge end of the feeding pipe.

[0010] In a further embodiment, the storage hopper is provided with a discharge port that penetrates the hopper body, and the hopper body is provided with a propulsion cylinder at one end of the sleeve. The output end of the propulsion cylinder is connected to the sleeve through an axial sliding-circumferential rotation composite coupling. The sleeve and the hopper body are movably connected through a linear bearing. The screw rod is movably connected to the feeding pipe, the receiving hopper and the sleeve.

[0011] In a further embodiment, the receiving chamber is provided with an air blowing pipe near the wall of the eyelet roller, the receiving chamber is provided with a lever extending out of the chamber body, the chamber body is provided with an arc-shaped hole at the lever, and an annular gap is provided between the outer wall of the receiving chamber and the inner wall of the eyelet roller, the gap width being 5-50mm.

[0012] In a further embodiment, the sprockets are interference-fitted with the auger, and chains are fitted onto both sprockets.

[0013] In a further embodiment, the movable roller is provided with roller sets at both ends and rolls with the storage bin and the bin body; the fixed roller is fixedly connected to the storage bin and the bin body; the fixed roller and the movable roller are coaxially arranged on the center line of the bin body; the receiving bin inside the fixed roller is fixedly connected to the feeding pipe of the movable roller.

[0014] In a further embodiment, a feed pipe is fitted onto the sleeve, the feed pipe is connected to the feed inlet of the movable roller, and the feed pipe and the sleeve are engaged by a rotating sealed bearing.

[0015] In a further embodiment, one end of the helical rod extending out of the cabin is connected to the output shaft of a second motor mounted on the cabin.

[0016] Beneficial effects: This utility model discloses a cleaning machine roller with adjustable hole depth. This utility model drives the sleeve to move axially through a propulsion cylinder, thereby causing the movable roller to separate or connect with the fixed roller, realizing automatic switching between single / multi-roller modes; the axial sliding-circumferential rotation composite coupling ensures that both the screw rod and the movable roller can rotate when the movable roller moves, avoiding power interruption;

[0017] The two screw rods are synchronously driven by sprockets and chains. The power transmission is always continuous, whether the drums are separated or combined. The movable drum rolls with the hopper / storage hopper through linear bearings or rollers, which reduces frictional resistance and facilitates rapid displacement.

[0018] The fixed and movable rollers are arranged coaxially to ensure precise alignment of the eyelet channels during docking, preventing material leakage. A 5-50mm annular gap is provided between the receiving chamber and the inner wall of the eyelet roller. With the airflow from the air blowing pipe, materials of the correct size are accurately introduced into the receiving chamber, preventing large particles from mixing in. Particles of different specifications are conveyed to the corresponding discharge baffles by the screw rod, achieving graded collection. Attached Figure Description

[0027] This utility model discloses a sorting machine roller with adjustable hole depth. A propulsion cylinder drives the sleeve to move axially, causing the movable roller to separate or connect with the fixed roller, achieving automatic switching between single / multi-roller modes. An axial sliding-circumferential rotation composite coupling ensures that both the screw rod and the movable roller can rotate during movement, avoiding power interruption. The specific implementation details the solution below.

[0028] Referring to Figures 1-7, a sorting machine drum with adjustable hole depth includes:

[0029] The chamber 1, the eyelet roller 2 disposed within the chamber 1, and the receiving chamber 3 disposed within the eyelet roller 2. The receiving chamber 3 is provided with an air blowing pipe 9 near the wall of the eyelet roller 2. The receiving chamber 3 is provided with a lever 33 extending out of the chamber 1. The chamber 1 is provided with an arc-shaped hole at the lever 33. An annular gap is provided between the outer wall of the receiving chamber 3 and the inner wall of the eyelet roller 2. The gap width is 5-50mm, which is used to introduce materials that meet the set size into the receiving chamber 3.

[0030] The eyelet roller 2 includes a fixed roller and a movable roller. The movable roller has roller sets at both ends and rolls with the storage bin 11 and the bin body 1. The fixed roller is fixedly connected to the storage bin 11 and the bin body 1. The fixed roller and the movable roller are coaxially arranged on the center line of the bin body 1. The receiving bin 3 inside the fixed roller is fixedly connected to the feeding pipe 31 of the movable roller.

[0031] The receiving chamber 3 is provided with a feeding pipe 31 on one side. The feeding pipe 31 and the receiving chamber 3 are provided with a screw rod 32. One end of the screw rod 32 extending out of the chamber 1 is connected to the output shaft of the second motor installed on the chamber 1. The screw rod 32 is movably connected to the feeding pipe 31, the receiving chamber 3 and the sleeve 10.

[0032] Two sprockets 4 are provided at their relative positions to drive each other. The sprockets 4 are interference-fitted with the sprockets 32, and chains are fitted on the two sprockets 4. The two ends of the sprockets 32 inside the movable roller are movably connected to the chamber 1 through bearings. An external toothed ring 21 is fitted on the outer wall of the eyelet roller 2. The external toothed ring 21 meshes with the output gear of the first motor located outside the chamber 1. A storage chamber 11 installed inside the chamber 1 is provided at the joint of the two eyelet rollers 2. The storage chamber 11 has a discharge port 12 that penetrates the chamber 1. One side of the movable roller is fitted on the sprockets 32 and extends... A sleeve 10 extends out of the chamber 1, and a conveying pipe 7 is fitted on the sleeve 10. The conveying pipe 7 is connected to the feed port 8 of the movable roller. The conveying pipe 7 and the sleeve 10 are connected by a rotating sealed bearing. The chamber 1 has a propulsion cylinder 6 at one end of the sleeve 10. The output end of the propulsion cylinder 6 is connected to the sleeve 10 through an axial sliding-circumferential rotation composite coupling. The sleeve 10 and the chamber 1 are movably connected by a linear bearing. The sleeve 10 is fixedly connected to the movable roller. The chamber 1 has multiple discharge baffles 5, which are located at the discharge end of the feeding pipe 31.

[0033] Working principle: When a single drum needs to work independently, the propulsion cylinder 6 retracts, pulling the sleeve 10 and the movable drum axially backward, separating them from the fixed drum (distance ≥100mm). The first motor only drives the outer toothed ring 21 of the fixed drum to rotate. The material enters the fixed drum from the conveying pipe 7 and is embedded in the eyelets as the drum rotates. Particles of the correct size are carried to a high position by the eyelets and fall into the receiving chamber 3 through the annular gap; oversized particles fall into the storage chamber 11 and are discharged through the outlet 12. The spiral rod 32 in the receiving chamber 3 pushes the material towards the feeding pipe 31, where it is collected in stages by the discharge baffle 5. The air blowing pipe 9 (installed at a 30° angle) assists in removing the residue from the eyelets.

[0034] When the two rollers need to work together, the propulsion cylinder 6 extends and pushes the sleeve 10 forward, so that the movable roller and the fixed roller are precisely connected. The outer toothed rings 21 of the two rollers mesh synchronously with the first motor, and the sprocket 4 drives the spiral rod 32 to rotate synchronously. The material first enters from the movable roller, and then the large particles are screened out from the fixed roller. The particles fall into the receiving chamber 3. Through the axial displacement of the movable roller and the superposition of the holes of the two rollers, the effective depth can be steplessly adjusted.

[0035] When it is necessary to adjust the tilt angle of the receiving chamber 3, loosen the flange bolts of the receiving chamber 3, rotate the lever 33 (through the arc hole of the chamber 1), adjust the angle between the receiving chamber 3 and the horizontal plane (15°-45°), tighten the bolts, and the air blowing pipe 9 will move in sync.

[0036] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
