The frame has a horizontally arranged fixed plate, and the side of the fixed plate facing the ground is arranged parallel to the ground and fixedly connected to the ground. This chain conveyor eliminates the supporting legs of the traditional chain conveyor, and the frame is directly fixed to the ground, which greatly reduces the height of the conveying surface of the conveyor and can play a role in the transportation of some heavy materials.

[0003] However, in this patent, the frame and other components are directly fixed to the ground through a fixed plate. On the one hand, the driving motor will generate vibration during long-term operation, which may cause the connection structure between the fixed plate and the ground to be damaged during long-term use; on the other hand, if heavy materials are transported for a long time, it is easy to cause deformation of the fixed plate, which actually limits the transportation capacity of the chain conveyor.

[0021] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0022] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0023] Example 1:

[0024] This embodiment provides a low conveying surface chain conveyor, which mainly includes two main components: a conveyor body 1 and a shock-absorbing mounting part 2.

[0025] like Figures 1 and 2 As shown, the conveyor main body 1 includes two symmetrically arranged frames 101, two conveyor chain assemblies 102 respectively arranged on the two frames 101, and a driving device 103 for driving the conveyor chain assemblies 102. The conveyor chain assemblies 102 mainly include a conveyor chain 102-1, at least two sets of driven wheel assemblies 102-3 and at least one driving wheel 102-2, wherein the two sets of driven wheel assemblies 102-3 are respectively arranged at both ends of the frames 101, and the conveyor chain 102-1 is sleeved on the driving wheel 102-2 and the driven wheel of the driven wheel assembly 102-3 to form a closed loop.

[0026] like Figure 2 As shown, the shock-absorbing mounting portion 2 is located at the bottom of the conveyor main body 1, used to mount the conveyor main body 1 on the ground while providing a shock-absorbing effect through its own structure. The shock-absorbing mounting portion 2 includes two sets of shock-absorbing kits 201, which are respectively installed at the bottom of the two sets of frames 101. Each set of shock-absorbing kits 201 includes two mounting bases 201-1, a guide rod 201-2, a first force component slider 201-3, and two first force component rods 201-4.

[0027] Two mounting bases 201-1 are disposed on the bottom of the rack 101, near each end. These mounting bases 201-1 can be block-shaped components mounted on the ground using bolts, expansion screws, or other structures, or they can be block-shaped structures directly cast on the ground using materials such as concrete. In this embodiment, the mounting bases 201-1 are concrete structures cast at designated locations on the ground. A first buffer member 201-5 is disposed between the mounting bases 201-1 and the bottom of the rack 101.

[0028] A guide rod 201-2 is connected between the two mounting bases 201-1. A first force component slider 201-3 is mounted on the guide rod 201-2. Second buffer components 201-6 are positioned between the two mounting bases and either side of the first force component slider 201-3. Two first force component rods 201-4 are movably connected to the bottom of the frame 101 at one end and to the first force component slider 201-3 at the other end. In this embodiment, the movably connected structure is achieved through a hinged structure.

[0029] Under the structure of the above-mentioned shock-absorbing mounting part 2, during the daily operation of the conveyor main part 1, the vibration caused by the driving device 103, etc. will be absorbed and alleviated by the first buffer component 201-5, thereby avoiding damage to the chain conveyor due to long-term friction or displacement between the conveyor main part 1 and the ground.

[0030] At the same time, Figure 2 Taking the installation of a low conveying surface chain conveyor shown as an example, it is used to convey materials from left to right. When the chain conveyor just receives a heavy material, the first buffer component 201-5 on the left side is compressed, and the conveyor body 1 tilts slightly to the left or forms a tilting trend, resulting in a decrease in the distance between the bottom of the frame 101 and the guide rod 201-2. In turn, the first force component slider 201-3 is driven to slide to the right or form a tendency to slide to the right through the first force component rod 201-4. At this time, the second buffer component 201-6 on the left side of the first force component slider 201-3 generates a pulling force, while the second buffer component 201-6 on the right side generates a pushing force. The two together drive the first force component slider 201-3 not to produce a large displacement on the guide rod 201-2, thereby enabling the first force component rod 201-4 on the left side to continue to provide support for the frame 101, ensuring that the left side of the frame 101 does not tilt significantly downward. At the same time, the first buffer component 201-5 on the right side also exerts a pulling force on the frame 101, preventing the frame 101 from tilting as a result of the right side lifting. Furthermore, the first force component rod 201-4 on the right side prevents the first force component slider 201-3 from shifting to the right. When heavy materials are moved to the right, the shock-absorbing mounting portion 2 similarly prevents the frame 101 from tilting significantly, ensuring smooth transportation of heavy materials to subsequent equipment.

[0031] Under this structure, heavy materials can be transported smoothly and normally, and at the same time, it can provide greater support force for the conveyor body, ensuring the long-term stable operation of the chain conveyor and being able to undertake the transportation of heavy materials.

[0032] Preferably, as shown in the figure, the shock absorbing assembly 201 further includes two second force component rods 201-7, a guide rail 201-8, and two second force component sliders 201-9. The guide rail 201-8 is mounted on the ground between the two mounting bases 201-1. The two second force component sliders 201-9 are movably mounted within the guide rails 201-8. A third shock absorbing component 201-10 is connected between the second force component sliders 201-9 and the adjacent mounting bases 201-1. One end of each second force component rod 201-7 is movably connected to a second force component slider 201-9, while the other end is movably connected to the first force component slider 201-3.

[0033] During the aforementioned heavy material conveying process, when the first force component slider 201-3 slides rightward or shows a tendency to slide, the second force component slider 201-9 on the left side is driven to slide rightward by the second force component rod 201-7 on the left side. However, at this time, the third buffer component 201-10 on the left side generates a pulling force, while the third buffer component 201-10 on the right side generates a pushing force, which together prevents the second force component slider 201-9 from deflecting significantly, thereby providing support to prevent the first force component slider 201-3 from sliding. This structure further enhances the support strength of the cushioning assembly 201, raising the upper limit of the material weight that the chain conveyor can transport.

[0034] Preferably, in this embodiment, Figure 1 As shown, the first buffer component 201-5, the second buffer component 201-6, and the third buffer component 201-10 are all elastic shock-absorbing components, specifically spring members. The second buffer component 201-6 is a spring component that is mounted outside the guide rod 201-2. The spring components can provide a pulling or pushing force to prevent the first force component slider 201-3 from deflecting. They can also absorb and mitigate small vibrations caused by components such as the drive device 103 in the conveyor body 1. In particular, the first buffer component 201-5 satisfies the need to reduce vibrations in the chain conveyor during long-term, routine transportation operations.

[0035] Preferably, if Figure 2As shown, in this embodiment, three receiving rods 104 are connected between the two sets of frames 101, wherein a driving device 103 is fixed on the receiving rod 104 in the middle, and the driving device 103 is connected to the driving wheel 102-2 in the two sets of conveyor chain kits 102 through a transmission shaft 105. On the one hand, one driving device 103 provides driving force for the two sets of conveyor chain kits 102 at the same time to ensure the synchronous operation of the two sets of conveyor chain kits 102; on the other hand, since the driving device 103 is one of the main sources of vibration, the driving device 103 is not installed on any of the frames 101, which ensures that not only one set of shock absorbing kits 201 needs to be used as the main force to bear the vibration of the conveyor main body 1, so that the two sets of shock absorbing kits 201 of the shock absorbing mounting part 2 can participate in the shock absorbing work, avoiding the situation where the performance of one set of shock absorbing kits 201 is first degraded during long-term use.

[0036] Preferably, a tensioning structure 106 is provided on the main plate 101-1 of the frame 101, and the tensioning structure 106 includes at least one tensioning wheel 106-1 in contact with the conveyor chain kit 102. The tensioning wheel 106-1 is in contact with the conveyor chain 102-1 to achieve a tensioning effect on the conveyor chain 102-1.

[0037] Preferably, as shown in the figure, in this embodiment, the conveyor chain assembly 102 includes two sets of driven wheel assemblies 102-3 and one driving wheel 102-2. The two driven wheel assemblies 102-3 are placed at both ends of the frame 101, and each set of driven wheel assemblies 102-3 includes two driven wheels. In this embodiment, the two driven wheels are arranged vertically; the driving wheel 102-2 is placed in the central area of ​​the frame 101. Simultaneously, the tensioning structure 106 includes two tensioning wheels 106-1, which are respectively arranged on either side of the top of the driving wheel 102-2 to tension the conveyor chain 102-1.

[0038] Among them, the contact point of the top of the driven wheel located above in the two sets of driven wheel groups 102-3 and in contact with the conveying chain 102-1 should be on the same horizontal plane as the contact point of the top of the tensioning wheel 106-1 and in contact with the conveying chain 102-1, so that the conveying chain 102-1 forms a horizontal conveying surface between the driven wheel group 102-3 and the tensioning wheel 106-1, and the conveying surface is higher than the driving wheel 102-2.

[0039] Because the two sets of driven wheels 102-3 are located on either side of the frame 101, and the driving wheel 102-2 is located in the center, to ensure a tight fit between the driving wheel 102-2 and the conveyor chain 102-1 and prevent slipping, the conveyor chain 102-1 typically needs to pass under the driving wheel 102-2. However, this structure effectively divides the conveying surface on the frame 101 into two sections, located on either side of the driving wheel 102-2. On the one hand, the presence of the driving wheel 102-2 results in a large gap between the two sections of the conveying surface, hindering the continuous conveying of materials. On the other hand, the contact of the conveyor chain 102-1 with the bottom of the driving wheel 102-2 causes the conveying surface to tilt. The structure in this embodiment ensures that the conveying chain 102-1 and the driving wheel 102-2 fit tightly together, so that the two parts of the conveying surface are supported by the tensioning wheel 106-1 and the driven wheel, and both can remain in a horizontal state; at the same time, the distance between the two parts of the conveying surface can be controlled by the distance between the two sets of tensioning wheels 106-1, thereby ensuring the smooth and stable transportation of materials as much as possible.

[0040] Preferably, the main plate 101-1 is provided with two horizontally extending tensioning grooves 106-2, with two tensioning wheels 106-1 movably mounted within each set of tensioning grooves 106-2. When the distance between the two tensioning wheels 106-1 decreases, the conveyor chain 102-1 is tensioned without affecting the horizontality of the conveyor surface.

[0041] Preferably, a guardrail 107 is provided on the outside of the frame 101. The guardrail 107 has a protective height higher than the conveying surface. Since the overall height of the chain conveyor in this embodiment is relatively low, the guardrail 107 can prevent surrounding personnel from directly stepping on or walking onto the conveying surface of the chain conveyor, thereby reducing the possibility of personal injury and material damage.

[0042] Example 2:

[0043] The difference between this embodiment and embodiment 1 is that, in this embodiment, Figure 3As shown, the first buffer component 201-5 is still an elastic shock-absorbing component, while the second buffer component 201-6 and the third buffer component 201-10 use a hydraulic rod kit. Because when the first component slider 201-3 moves, the second buffer component 201-6 and the third buffer component 201-10 may need to provide thrust in some cases. For example, when the frame 101 tilts to the left, the second buffer component 201-6 and the third buffer component 201-10 on the left side provide tension, while the second buffer component 201-6 and the third buffer component 201-10 on the right side need to provide thrust. The performance of the hydraulic rod kit in providing tension is similar to that of the elastic shock-absorbing component, but the thrust that the hydraulic rod kit can provide is always relatively constant, especially after long-term use. The hydraulic rod kit can still provide a large thrust. In addition, the hydraulic rod kit can also provide different amounts of thrust by adjusting the hydraulic pressure in the rod, which ultimately provides different amounts of support force for the conveyor body 1, which actually expands the scope of application of the chain conveyor.

[0044] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
