Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a rake material machine. Background Technology

[0002] A rake is a material conveying device. In the glass production process, its main task is to continuously rake granular materials, such as silica sand, from the stockpile and then convey the materials to the next production station.

[0003] A raking machine typically consists of a frame, motor, chain, and buckets. The motor drives the chain, which in turn moves the buckets around the frame, enabling continuous raking and conveying of materials. In actual production, because the buckets need to bear heavy materials, they are prone to swaying during transport, resulting in poor stability. The edges of the buckets are easily damaged by the frame, and the chain is also easily damaged by the frequent swaying. Over time, both the buckets and the frame will experience wear, and the chain's lifespan will be significantly shortened, leading to frequent maintenance, high upkeep costs, and a slowdown in production. Utility Model Content

[0004] The main purpose of this invention is to propose a rake machine that aims to improve the stability of the hopper during the conveying process.

[0005] To achieve the above objectives, the present invention provides a rake feeder comprising: frame; A conveying assembly, wherein the conveying assembly is disposed on the frame; A hopper, the bottom of which is connected to the conveying assembly, so as to move along a first direction under the drive of the conveying assembly; A guiding assembly includes a guide member and two limiting members. The two limiting members are arranged at intervals along a second direction to enclose and form a limiting channel. One of the guide member and the limiting members is connected to the bottom of the hopper, and the other is connected to the frame. The one connected to the frame extends along a first direction. The guide member moves within the limiting channel. The second direction is perpendicular to the first direction.

[0006] In one embodiment, the guide is a roller, which is rotatably connected to the bottom of the hopper, and the two limiting members extend along the first direction and are connected to the frame.

[0007] In one embodiment, the guide assembly further includes a support bolt and a mounting nut, the support bolt being mounted to the hopper via the mounting nut, and the roller being rotatably connected to the support bolt.

[0008] In one embodiment, the guide assembly further includes a support plate, the support plate including a support section and a connecting section that are angled to each other, the connecting section being connected to the bottom of the hopper, both the support section and the hopper having mounting holes, and the support bolt passing through the mounting holes and being connected to the mounting nut.

[0009] In one embodiment, the depth of the limiting channel is greater than the thickness of the guide member, and the distance between the lower surface of the support plate and the limiting channel is less than the thickness of the guide member.

[0010] In one embodiment, the guide is connected to the middle of the hopper, and both ends of the hopper are connected to the conveying assembly.

[0011] In one embodiment, a limiting channel is formed between the two limiting members, and the limiting channel is sequentially configured as an inlet segment, a limiting segment, and an outlet segment along the first direction, wherein the width of the inlet segment and the width of the outlet segment are both greater than the width of the limiting segment.

[0012] In one embodiment, the limiting member is a square steel component.

[0013] In one embodiment, the hopper is connected to a rake plate, which is made of polyurethane.

[0014] In one embodiment, the conveying assembly includes a motor, a chain, and two sprockets. The two sprockets are respectively disposed at both ends of the frame along the first direction. The chain is wound around the two sprockets. The motor is connected to one of the sprockets. The hopper is connected to the chain.

[0015] In the technical solution of this utility model, the frame is the supporting structure of the entire equipment, providing a foundation for the installation and support of other components. The hopper is used to load and push materials. The bottom of the hopper is connected to the conveying assembly, which drives the hopper to move along a first direction, conveying the material from the stockpile to the next production station. The guiding assembly includes a guide member and two limiting members. The two limiting members enclose and form a limiting channel. During the process of the conveying assembly driving the hopper to convey materials along the first direction, the guide member slides within the limiting channel. The two limiting members prevent the guide member from moving in a second direction, ensuring that the hopper can move along the first direction during conveying, thereby avoiding swaying of the hopper during material conveying, improving the stability of the hopper during movement, preventing wear caused by the hopper colliding with the frame, extending the service life of the hopper and frame, reducing maintenance frequency, and ensuring production stability.

[0023] A rake is a material conveying device. In the glass production process, its main task is to continuously rake granular materials, such as silica sand, from the stockpile and then convey the materials to the next production station.

[0024] A raking machine typically consists of a frame, motor, chain, and buckets. The motor drives the chain, which in turn moves the buckets around the frame, enabling continuous raking and conveying of materials. In actual production, because the buckets need to bear heavy materials, they are prone to swaying during transport, resulting in poor stability. The edges of the buckets are easily damaged by the frame, and the chain is also easily damaged by the frequent swaying. Over time, both the buckets and the frame will experience wear, and the chain's lifespan will be significantly shortened, leading to frequent maintenance, high upkeep costs, and a slowdown in production.

[0025] To address this technical problem, this invention proposes a rake-type material feeder that can improve the stability of the hopper during the conveying process.

[0026] Please see Figures 1 to 4 In one embodiment of this utility model, the rake 100 includes a frame 1, a conveying assembly, a hopper 3, and a guiding assembly 4. The conveying assembly is disposed on the frame 1, and the bottom of the hopper 3 is connected to the conveying assembly so as to move along a first direction under the drive of the conveying assembly. The guiding assembly 4 includes a guide member 41 and two limiting members 42. The two limiting members 42 are arranged at intervals along a second direction to form a limiting channel 43. One of the guide member 41 and the limiting member 42 is connected to the bottom of the hopper 3, and the other is connected to the frame 1. The one connected to the frame 1 extends along the first direction. The guide member 41 moves within the limiting channel 43, and the second direction is perpendicular to the first direction.

[0027] Specifically, such as Figure 1 and Figure 2As shown, the conveying assembly drives the hopper 3 to move around the frame 1, thereby continuously conveying materials from the stockpile to the next production station. The second direction is the left-right direction. Since the hopper 3 moves around the frame 1, the first direction is a constantly changing direction, which can be understood as the front-back direction or the up-down direction; in short, it is a direction perpendicular to the second direction. For ease of understanding, in this embodiment, the front-back direction is used as an example for explanation.

[0028] In the technical solution of this utility model, the frame 1 is the supporting structure of the entire equipment, providing a foundation for the installation and support of other components. The hopper 3 has an overall L-shaped structure, which can load and push materials. The bottom of the hopper 3 is connected to the conveying component, which drives the hopper 3 to move along the first direction, conveying the material from the stockpile to the next production station. The guide component 4 ensures that the hopper 3 can move along the first direction during the transmission process, avoiding swaying of the hopper 3 during the movement.

[0029] Specifically, such as Figure 1 As shown, the guiding assembly 4 includes a guide member 41 and two limiting members 42. The two limiting members 42 are spaced apart in the left-right direction to form a limiting channel 43. The limiting channel 43 extends in the front-back direction. When the conveying assembly drives the hopper 3 to convey materials in the first direction, the guide member 41 slides in the limiting channel 43. The two limiting members 42 can prevent the guide member 41 from moving in the second direction, which can prevent the hopper 3 from moving in the second direction. This prevents the hopper 3 from shaking during the material conveying process, improves the stability of the hopper 3 during the movement, avoids wear caused by the hopper 3 colliding with the frame 1, extends the service life of the hopper 3 and the frame 1, reduces the maintenance frequency, and ensures the stability of production.

[0030] In one embodiment of this utility model, two limiting members 42 are fixedly connected to the frame 1, including but not limited to welding and bolt connection, while the guide member 41 is located at the bottom of the hopper 3. With this arrangement, the structure of the limiting member 42 is more stable, which can provide better limiting effect for the guide member 41 and better prevent the hopper 3 from swaying left and right.

[0031] In another embodiment of this utility model, the two limiting members 42 can be fixedly connected to the bottom of the hopper 3, including but not limited to welding and bolt connection, while the guide member 41 is fixedly connected to the frame 1, for example, welded to the frame 1. Specifically, in this embodiment, the limiting member 42 is a pulley and the guide member 41 is a long track. With this arrangement, the movement of the hopper 3 in the left and right directions can also be restricted, that is, the hopper 3 is prevented from shaking during the material conveying process.

[0032] In one embodiment of this utility model, the guide member 41 is a roller, which is rotatably connected to the bottom of the hopper 3, and the two limiting members 42 extend along the first direction and are connected to the frame 1.

[0033] Specifically, such as Figure 1 As shown, two limiting members 42 are spaced apart in the left-right direction, with the distance between them slightly larger than the outer diameter of the roller. This limits the left-right swaying of the roller while preventing it from affecting the roller's movement within the limiting channel 43. Furthermore, by designing the roller, the friction between the roller and the limiting member 42 is rolling friction, which reduces the resistance during the movement of the hopper 3, making its movement smoother. In addition, since the guide member 41 touches the limiting member 42 during movement, the limiting member 42 can, to some extent, share some of the load on the hopper 3, extending its service life.

[0034] In another embodiment of this utility model, the guide member 41 can also be a block-shaped component adapted to the limiting channel 43, such as a cube iron block, which can also cooperate with the two limiting members 42 to jointly restrict the movement direction of the hopper 3 and prevent the hopper 3 from shaking during the material conveying process.

[0035] In another embodiment of this utility model, the limiting channel 43 can also be formed by the structure of the frame 1 itself, for example, by setting a groove on the frame 1, which can also play the role of limiting and guiding.

[0036] In one embodiment of this utility model, such as Figure 3 As shown, the guide assembly 4 also includes a support bolt 44 and a mounting nut 45. The support bolt 44 is mounted on the hopper 3 by the mounting nut 45, and the roller is rotatably connected to the support bolt 44.

[0037] Specifically, during installation, the head of the support bolt 44 is located below the screw, providing support for the roller. The screw of the support bolt 44 includes a smooth part and a threaded part. The guide 41 is fitted onto the smooth part, enabling rotation. There are two mounting nuts 45. The threaded part located on the upper part of the support bolt 44 is first threaded to one of the mounting nuts 45, and then the threaded part passes upward through the hopper 3 and is threaded to the other mounting nut 45. More specifically, the hopper 3 includes a horizontal part and a vertical part. The threaded part of the support bolt 44 passes upward through the horizontal part of the hopper 3 and is threaded to the other mounting nut 45. With this arrangement, the guide 41 can be securely installed on the hopper 3 without affecting the rotation of the guide 41, resulting in a very stable overall structure.

[0038] In one embodiment of this utility model, the roller is provided with a bearing inside, and the bearing is sleeved on the smooth part of the support bolt 44, so that the roller rotates more smoothly.

[0039] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the guide assembly 4 also includes a support plate 46, which includes a support section and a connecting section that are at an angle to each other. The connecting section is connected to the bottom of the hopper 3. Both the support section and the hopper 3 are provided with mounting holes 5. The support bolt 44 passes through the mounting hole 5 from bottom to top and is connected to the mounting nut 45.

[0040] Specifically, the support plate 46 has an overall L-shaped structure. The support plate 46 includes a vertical part and a horizontal part. The vertical part is a connecting section. The upper end of the vertical part is fixedly connected to the bottom of the hopper 3, for example, by welding or detachably connecting to the bottom of the hopper 3. The horizontal part is a support section. The horizontal part is located at the lower end of the vertical part. The horizontal part is provided with mounting holes 5. The mounting holes 5 of the horizontal part and the mounting holes 5 on the hopper 3 are coaxially arranged. The support bolt 44 passes through the mounting holes 5 from bottom to top and is connected to the mounting nut 45.

[0041] With this configuration, the two mounting holes 5 provide two fixing points for the support bolt 44, preventing the support bolt 44 from shaking after installation. In addition, the horizontal portion of the support plate 46 also acts as a limit, preventing the guide member 41 from moving vertically and from leaving the limiting channel 43, ensuring that the guide member 41 is always confined between the two limiting members 42, thus more stably preventing the hopper 3 from shaking.

[0042] In one embodiment of this utility model, the depth of the limiting channel 43 is greater than the thickness of the guide member 41, and the distance between the lower surface of the support plate 46 and the limiting channel 43 is less than the thickness of the guide member 41. With this arrangement, the guide member 41 can be prevented from disengaging from the limiting channel 43 during movement, and the guide member 41, as a roller, can also achieve a better rolling effect, resulting in higher overall stability.

[0043] In one embodiment of this utility model, the guide member 41 is connected to the middle of the hopper 3, and the two ends of the hopper 3 are connected to the conveying assembly. The overall structure is more stable, the stress of the entire hopper 3 is more concentrated, and the risk of the hopper 3 shaking is reduced.

[0044] In one embodiment of this utility model, such as Figure 1 As shown, a limiting channel 43 is formed between the two limiting members 42. The limiting channel 43 is sequentially configured as an inlet section, a limiting section, and an outlet section along the first direction. The width of the inlet section and the width of the outlet section are both greater than the width of the limiting section.

[0045] Specifically, when the guide member 41 enters the limiting channel 43, the width of the inlet section is greater than the width of the limiting section, allowing the guide member 41 to enter the limiting section more smoothly and accurately, ensuring that the limiting section can effectively limit the guide member 41 and prevent the hopper 3 from shaking. The width of the outlet section is greater than the width of the limiting section, allowing the guide member 41 to leave the entire limiting channel 43 more quickly and smoothly, avoiding jamming or collision at the outlet of the limiting channel 43, and ensuring the continuity and smoothness of the material scraping operation.

[0046] In one embodiment of this utility model, the limiting member 42 is elongated, which can save materials and reduce production costs.

[0047] In another embodiment of this utility model, the limiting member 42 can also be a horizontal plate shape, which makes the overall structure more stable and can provide better support for the guide member 41 in the left and right directions.

[0048] In one embodiment of this utility model, the limiting member 42 is made of square steel, which has a stable structure, is not easily deformed, and has low cost, thus reducing production costs.

[0049] Furthermore, the limiting member 42 is welded from three sections of square steel. It can be understood that the three sections of square steel are located correspondingly in the entrance section, the limiting section, and the exit section of the limiting channel 43. The square steel in the entrance section and the square steel in the exit section are both inclined to the side away from the limiting channel 43. In this way, the limiting channel 43 with the above structure can be formed between the two limiting members 42. That is, the width of the entrance section and the width of the exit section are both greater than the width of the limiting section. Such a limiting member 42 is easy to manufacture and has a stable structure.

[0050] In one embodiment of this utility model, such as Figure 3 As shown, the hopper 3 is connected to a rake plate 6, and the upper end of the rake plate 6 is provided with a pointed protrusion, which can better rake the material.

[0051] In one embodiment of this invention, the rake plate 6 is made of polyurethane. Polyurethane has excellent wear resistance, and its service life under long-term material friction far exceeds that of metal plates. This significantly reduces the replacement frequency and maintenance costs of the rake plate 6, and minimizes downtime. Furthermore, polyurethane exhibits stable performance in corrosive environments and is not easily corroded, ensuring reliable equipment operation. Finally, polyurethane is relatively soft and causes minimal damage to materials. During the rakeing process, it better conforms to the shape of the material, avoiding potential scratches or deformation caused by iron rake plates, thus improving material quality.

[0052] In one embodiment of the present invention, the conveying assembly includes a motor, a chain 2 and two sprockets. The two sprockets are respectively disposed at both ends of the frame 1 along a first direction. The chain 2 is wound around the two sprockets. The motor is connected to one of the sprockets. The hopper 3 is connected to the chain 2.

[0053] Specifically, chains 2 are provided on both sides of the limiting channel 43. The two ends of the hopper 3 are fixedly connected to the chains 2 on both sides, for example, welded to a chain 2. The motor drives the sprocket to rotate, thereby driving the chain 2 to rotate, and then driving the hopper 3 to move, making the movement of the hopper 3 more stable and smooth.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
