Description

Technical Field

[0001] The utility model relates to, in particular to, a conveyor for breaking up materials. Background Art

[0002] Crawler color sorters are widely used in industries such as food, pharmaceuticals, renewable resources, and mining. Due to their inherent stickiness, materials like kelp and pickled bamboo shoots can clump together during conveying, leading to poor sorting results. Conventional solutions involve manual or machine-assisted breakup during conveying, which is time-consuming and labor-intensive, and can also lead to secondary contamination of the material. Traditional breakup machines are unable to evenly distribute the material, and some machines have sharp breakup components, which can break fragile materials during the process.

[0003] A search revealed that Chinese patent CN115245915A discloses a high-precision food color sorter. The color sorter includes a material sorting mechanism, which includes a mounting frame equipped with a scraper plate. The scraper plate faces the conveyor belt and flattens the material on the conveyor belt, limiting the amount of material passing through. A certain distance is maintained between the lower portion of the scraper plate and the conveyor belt surface, and the distance is adaptively adjusted according to the size of the material particles. Bristles are provided on the lower edge of the scraper plate. This solution relies on the bristles to evenly brush the material particles. While it can flatten the material on the conveyor belt to a certain extent, due to the uneven size of the material and the small force applied by the bristles to the clumping material due to the fixed scraper plate, the smoothing effect cannot be guaranteed, and there is still the problem of damaging fragile materials. Utility Model Content

[0004] The purpose of the present invention is to provide a conveyor for breaking up materials in order to overcome the defects of the prior art in that the paving effect cannot be guaranteed and the fragile materials may be damaged.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] The utility model provides a conveyor for breaking up materials, comprising a drive assembly and a roller assembly and a conveying assembly respectively driven and connected to the drive assembly, the conveying assembly comprising an input end and an output end, the roller assembly comprising a multi-stage roller sequentially connected above the conveying assembly from the input end to the output end, the rotation direction of each stage of the roller being opposite to the conveying direction of the conveying assembly, and the gap height between each stage of the roller and the conveying assembly decreasing step by step from the input end to the output end.

[0007] As a preferred technical solution, the conveyor further includes a support assembly, the drive assembly is fixedly connected to the support assembly, and the conveying assembly is fixedly connected above the support assembly.

[0008] As a preferred technical solution, the conveyor further includes a side guard assembly, and the side guard assembly is fixedly connected to both sides of the conveying assembly.

[0009] As a preferred technical solution, each level of the roller includes a roller shaft and a material-breaking element. The two ends of the roller shaft are movably connected to the two sides of the conveying component. The moving direction of the roller shaft is perpendicular to the conveying direction of the conveying component. The material-breaking element is evenly connected to the surface of the roller shaft.

[0010] As a preferred technical solution, the material-scattering element is a brush.

[0011] As a preferred technical solution, the conveyor also includes a side mounting bracket and a bearing base, the side mounting bracket is fixedly connected to both sides of the conveying assembly, the bearing base is movably connected to the opposite side of the side mounting bracket, and the end of the roller shaft is fixedly connected to the bearing base.

[0012] As a preferred technical solution, the conveyor further includes a fastener, the bearing base is provided with a slot, and the fastener passes through the slot to connect the side mounting bracket and the bearing base.

[0013] As a preferred technical solution, the conveying assembly includes a driving shaft, a driven shaft and a conveyor belt. The driving shaft is driven and connected to the driving assembly. The driving shaft and the driven shaft are located at the input end and the output end respectively. The conveyor belt is sleeved outside the driving shaft and the driven shaft.

[0014] As a preferred technical solution, the driving assembly includes a box and a first motor and a second motor connected to the inside of the box in sequence. The number of the first motors corresponds to the number of rollers. The first motor is driven and connected to the corresponding rollers, and the second motor is driven and connected to the conveying assembly.

[0015] As a preferred technical solution, both the first motor and the second motor are servo motors.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The utility model is equipped with multi-stage rollers. From the input end to the output end of the conveyor belt, the gap height between each stage roller and the conveyor belt surface gradually decreases to achieve graded material sorting. It can adapt to materials of different sizes and heights and effectively improve the effect of breaking up the materials.

[0018] 2. In the present invention, the direction of rotation of the drum is opposite to the conveying direction of the conveyor belt. In the process of breaking up the materials, the movement of the drum and the conveyor belt in opposite directions makes the force applied by the brush to the clumped materials large enough, so that the materials above the height of the gap between the drum and the conveyor belt can be spread in the direction opposite to the conveying direction of the conveyor belt. When the spread materials pass through the conveyor belt and then through the gap under the drum at the corresponding height, the brush can brush the spread materials again. At this time, the impact of the brush on the materials is relatively small. That is, through the two-stage action, it can not only effectively improve the effect of breaking up and leveling the materials, but also minimize the probability of damaging fragile materials.

[0019] 3. In the present invention, the end of the roller shaft is fixedly connected to the bearing base, and a notch is provided in the bearing base. Fasteners are passed through the notch to connect the side mounting bracket to the bearing base, that is, to connect the side mounting bracket to the roller shaft. This connection method is a waist hole connection, which can realize the free adjustment of the roller height to further meet the requirements of different sizes of materials and the disintegration effect.

[0020] 4. The conveyor provided by this utility model is designed with multiple components, which is compatible with more models and effectively improves the adaptability of the scene;

[0021] 5. The conveying surface of the conveyor provided by the utility model can be washed with water, which is beneficial to cleaning and prolonging the service life. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0029] Example:

[0030] This embodiment provides a conveyor for breaking up materials, such as Figure 1 As shown, the conveyor includes a drive assembly 1 and a roller assembly 2 and a conveying assembly 3 respectively driven and connected to the drive assembly 1. The conveying assembly 3 includes an input end and an output end. The roller assembly 2 includes a multi-stage roller connected to the top of the conveying assembly from the input end to the output end. The rotation direction of each stage of the roller is opposite to the conveying direction of the conveying assembly 3, and the gap height between each stage of the roller and the conveying assembly 3 decreases step by step from the input end to the output end.

[0031] like Figure 2 and Figure 3As shown, in this embodiment, the roller assembly 2 comprises two stages of rollers: a first-stage roller 21 and a second-stage roller 22. The conveyor assembly 3 comprises a driving shaft, a driven shaft, and a conveyor belt 31. The driving shaft is drivingly connected to the drive assembly 1, with the driving shaft and the driven shaft located at the input and output ends of the conveyor assembly 3, respectively. The conveyor belt 31 is sleeved around the driving and driven shafts. When the drive assembly 1 is activated, it drives the driving shaft to rotate, which in turn, together with the driven shaft, drives the conveyor belt 31 to transport the material.

[0032] Each level of the roller includes a roller shaft 210 and a material-scattering element 211. The two ends of the roller shaft 210 are movably connected to the two sides of the conveying component 3. The moving direction of the roller shaft 210 is perpendicular to the conveying direction of the conveying component 3. The material-scattering element 211 is evenly connected to the surface of the roller shaft 210.

[0033] In this embodiment, the material-scattering element 211 is a brush.

[0034] In some other embodiments, the angle between the moving direction of the roller shaft 210 and the conveying direction of the conveying component 3 can be between 0° and 90°. At this time, the horizontal distance between adjacent rollers can be adjusted according to the weight of different components in the input material while adjusting the roller height, so that the material breaking effect can be guaranteed in more diverse scenarios.

[0035] like Figure 3 As shown, the two ends of the roller shaft 210 are movably connected to the two sides of the conveying component 3. The specific implementation method is as follows:

[0036] The conveyor also includes side mounting brackets 23 and bearing bases 24, with the roller shaft 210 fixedly connected to the bearing bases 24. The side mounting brackets 23 are fixedly connected to both sides of the conveyor assembly 3. The side mounting brackets 23 are thin plates that can be vertically mounted on either side of the conveyor assembly 3 without taking up too much space. The bearing bases 24 define slots 241, which are connected to the side mounting brackets 23 by fasteners that pass through the slots 241. These fasteners are screws.

[0037] By adjusting the tightness of the screws between the two side mounting brackets 23 and the bearing base 24, the vertical displacement of the drum shaft 210 can be controlled. Specifically:

[0038] When the screw is loosened, the bearing base 24 can move up and down along the screw, generating relative displacement with the side mounting bracket 23, and the bearing base 24 drives the roller shaft 210 fixedly connected thereto to move up and down; when the screw is tightened, the bearing base 24 is fixedly connected to the side mounting bracket 23 at a selected position, and the position of the roller shaft 210 is also fixed.

[0039] On this basis, the gap height between each level of rollers and the conveying assembly 3 can be gradually reduced by the following methods:

[0040] Adjust the screw to control the up and down displacement of the roller shaft of the first-stage roller 21 according to the size of the material, and then adjust the gap height between the first-stage roller 21 and the conveyor belt 31, so that the material can be classified for the first time when passing through the gap. At the same time, control the up and down displacement of the roller shaft of the second-stage roller 22, and then adjust the gap height between the second-stage roller 22 and the conveyor belt 31, so that the former gap height is greater than the latter gap height, thereby achieving graded material sorting.

[0041] like Figure 1 As shown, the conveyor provided in this embodiment also includes a support assembly 4, to which the drive assembly 1 is fixedly connected, and the conveying assembly 3 is fixedly connected above the support assembly 4. Specifically, the support assembly 4 is a frame structure, including four support legs, adjacent support legs connected by crossbeams. Crossbeams are provided near the top and bottom ends of the support legs to increase the stability of the entire conveyor. The conveying assembly 3 is fixedly connected to the top of the support legs by fasteners, and the drive assembly 1 is fixedly connected to the bottom crossbeam on one side.

[0042] like Figure 1 As shown, the conveyor provided in this embodiment also includes a sidewall assembly 5, which is fixedly connected to both sides of the conveying assembly 3. Specifically, the sidewall assembly 5 includes two long strip structures, which are arranged on both sides of the conveying assembly 3 relative to each other. The length of the sidewall assembly 5 is slightly smaller than the length of the entire conveying assembly 3. By adjusting the distance between the two long strip structures, the distance between the material entering the conveying assembly 3 and the edge of the conveyor belt 31 can be adjusted.

[0043] The working principle of the conveyor provided in this embodiment is as follows:

[0044] The clumped and stuck materials are transported to the conveyor assembly 3 via an elevator. The conveyor belt 31 of the conveyor assembly 3 transports the materials forward. As the materials pass through the roller assembly 2 mounted on the conveyor assembly 3, the rotation of each roller is opposite to the conveying direction of the conveyor belt 31. Therefore, the materials above the gap between the roller and the conveyor belt 31 are spread in the opposite direction of the conveyor belt 31's movement. The conveyor belt 31 then transports the spread materials to the bottom of the roller, where the corresponding brushes further evenly spread the materials on the conveyor belt 31. This process is repeated until the height of all materials is less than or equal to the gap between the roller and the conveyor belt 31. Since the rollers randomly spread the stacked materials on the conveyor belt 31 as they spread backward, the materials are evenly distributed on the surface of the conveyor belt 31. Multiple rollers can be installed with different height gaps to perform graded material sorting to achieve better material dispersion.

[0045] In some embodiments, the drive assembly 1 includes a housing and first and second motors connected to the housing. The number of first motors corresponds to the number of rollers, and the first motors are drivingly connected to the corresponding rollers, while the second motors are drivingly connected to the conveyor assembly 3. Specifically, the second motor is drivingly connected to the driving shaft, driving the driving shaft to rotate. The driving shaft and the driven shaft jointly drive the conveyor belt 31. Each motor can be independently controlled in speed. The division of labor between the first and second motors ensures that the direction of rotation of the rollers is opposite to the conveying direction of the conveyor belt 31.

[0046] In some embodiments, the first motor and the second motor are both servo motors.

[0047] In summary, the conveyor provided by the present invention has enhanced material sorting function compared with the existing color sorter, which is specifically reflected in the following aspects:

[0048] 1. Each roller can be controlled by a separate servo motor. Multiple rollers can be installed on a single conveying assembly, and multi-level speed adjustment can be performed according to the material conveying speed.

[0049] 2. The roller assembly is connected to the side with waist holes, and the roller height can be adjusted freely to meet the needs of different sizes of materials and the needs of breaking up the materials;

[0050] 3. The roller adopts a soft brush roller, which can reduce the damage to the material during the process of breaking up the material, and at the same time can spread the material evenly on the conveyor belt.

[0051] 4. The applicability of the conveyor is enhanced. Each component of the conveyor is a separate component. Its size can be changed according to the supporting machine, and it can be applied to more types of models.

[0052] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
