Description

Technical Field

[0001] This utility model relates to the technical field of asphalt production equipment, specifically to a raw material conveying device for asphalt production. Background Technology

[0002] In the asphalt production process, raw materials need to be fed into conveying equipment via a receiving hopper. Current conveying equipment generally suffers from a technical problem: when workers pour raw materials into the receiving hopper, errors in human operation, such as incorrect pouring position, excessive pouring speed, or inaccurate alignment between the hopper opening and the transport vehicle, easily lead to raw materials spilling outside the hopper. Spilled raw materials not only waste materials and increase production costs but also pollute the working environment and may even cause equipment malfunctions or safety hazards due to material accumulation. Therefore, there is an urgent need to design a raw material conveying device that can reduce spillage caused by human error in feeding. Summary of the Invention

[0003] The technical problem to be solved by this utility model is how to solve the problem of raw material spillage caused by manual feeding errors in the prior art.

[0004] The technical solution adopted by this utility model is: a raw material conveying device for asphalt production, including a conveyor frame and a conveyor belt set on the conveyor frame for conveying materials. A receiving hopper is provided on one side of the conveyor frame, a recycling hopper is provided on the outside of the receiving hopper, and bucket frames for supporting the recycling hopper are provided on both sides of the recycling hopper.

[0005] The above structure has the following beneficial effects:

[0006] By setting a receiving hopper on one side of the conveyor frame and a recycling hopper on the outside of the receiving hopper, and fixing the recycling hopper with hopper frames on both sides, not only is efficient material conveying achieved, but also raw materials spilled or overflowed during the conveying process can be effectively collected, avoiding waste and environmental pollution. In addition, the frequency of manual cleaning and maintenance is effectively reduced, improving the overall stability and continuous operation of the equipment.

[0007] Preferably, the angle between the bottom of the recycling hopper and the side wall of the receiving hopper is an acute angle.

[0008] By designing the angle between the bottom of the recycling hopper and the side wall of the receiving hopper as an acute angle, it is beneficial to allow the material spilled into the recycling hopper to slide to the bottom of the recycling hopper, reducing the accumulation of material on the inner wall of the recycling hopper, reducing the occurrence of blockage, and thus improving the material recycling efficiency.

[0009] Preferably, the receiving hopper has through holes on its side wall.

[0010] By setting through holes on the side wall of the receiving hopper, it is helpful to discharge the material recovered into the recycling hopper in a timely manner through the through holes along the side wall of the recycling hopper into the receiving hopper, avoiding the tedious step of manually recovering the material accumulated in the recycling hopper and then putting it into the receiving hopper.

[0011] Preferably, the inner wall of the bottom end of the recycling hopper is in contact with the bottom surface of the through hole.

[0012] By connecting the bottom of the inner wall of the recycling hopper with the bottom surface of the through hole, the design ensures that the material recycled into the recycling hopper can flow smoothly into the receiving hopper, avoiding the problem of material jamming. This design effectively enhances the continuity of material conveying from the recycling hopper to the receiving hopper.

[0013] Preferably, a support rod is provided between the outer wall of the receiving hopper and the inner wall of the recycling hopper.

[0014] By installing support rods between the outer wall of the receiving hopper and the inner wall of the recycling hopper, the connection strength and overall stability between the receiving hopper and the recycling hopper are effectively enhanced. This effectively prevents displacement or deformation caused by material impact or equipment vibration, improves the load-bearing capacity and service life of the equipment, and ensures safe operation.

[0015] Preferably, the support rod is positioned diagonally between the receiving hopper and the recycling hopper.

[0016] By arranging the support rods diagonally between the receiving hopper and the recycling hopper, the force distribution is more uniform, enhancing the overall rigidity and deformation resistance of the structure, improving the stability and reliability of the equipment under complex working conditions, optimizing space utilization, and providing a guarantee for the long-term operation of the equipment.

[0017] Preferably, the cross-section of the support rod is "L" shaped.

[0018] The support rod with an "L" shaped cross section not only has strong bending resistance and load-bearing capacity, but also takes into account the lightweight structure. When materials are spilled onto the support rod, because the support rod is "L" shaped, the spilled materials will slide down the inclined surface of the support rod into the recycling hopper, reducing the frequency of manual cleaning of materials spilled onto the support rod later.

[0019] Preferably, the outer wall of the recycling hopper is equipped with a hopper wall vibrator.

[0020] Installing a hopper wall vibrator on the outer wall of the recycling hopper can effectively prevent materials from adhering, clumping, or clogging inside the hopper, improve material flowability and recycling efficiency, reduce manual cleaning workload, enhance the continuous operation capability of the equipment, and ensure smooth and efficient operation of the equipment.

[0021] Preferably, at least four bin vibrators are provided.

[0022] By installing at least four bin wall vibrators on the recycling hopper, it is ensured that all four sides of the recycling hopper can be vibrated, eliminating dead corners where materials are stuck, improving the emptying rate and flowability, and enabling the equipment to effectively cope with high-volume, long-term operation conditions.

[0023] As a preferred option, baffles are also installed on both sides of the conveyor to prevent material spillage.

[0024] By installing baffles on both sides of the conveyor belt, it is possible to effectively prevent the material storage cabinet conveyor belt from falling off. Attached Figure Description

[0031] The following will be combined with the appendix Figure 1-4 The technical solution of this utility model is clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Example

[0034] The following description, in conjunction with specific embodiments, provides further details. Figure 1-4 As shown, this embodiment is a raw material conveying device for asphalt production, including a conveyor frame 1 and a conveyor belt 1001 mounted on the conveyor frame 1 for conveying materials. A receiving hopper 3 is provided on one side of the conveyor frame 1, and a recycling hopper 4 is provided on the outer side of the receiving hopper 3. The bottom end of the recycling hopper 4 is fixed to the side wall of the receiving hopper 3 by welding, and bucket frames 2 are provided on both sides of the recycling hopper 4 to fix the recycling hopper 4.

[0035] Furthermore, in order to ensure that the material collected in the recycling hopper 4 can be discharged from the through hole 3001 along the side wall of the recycling hopper 4 into the receiving hopper 3 in a timely manner, and to avoid the tedious steps of manually cleaning up the material and then putting the recycled material into the receiving hopper 3 after excessive accumulation of material, a through hole 3001 is provided on the side wall of the receiving hopper 3, and the bottom inner wall of the recycling hopper 4 is connected to the bottom surface of the through hole 3001. This design can effectively prevent the material in the recycling hopper 4 from getting stuck when sliding into the receiving hopper 3. Baffles 1002 are also provided on both sides of the conveyor frame to prevent the material from spilling.

[0036] In addition, a support rod 5 is installed between the outer wall of the receiving hopper 3 and the inner wall of the recycling hopper 4. The support rod 5 is positioned diagonally between the receiving hopper 3 and the recycling hopper 4, and its cross-section is "L"-shaped. This design effectively enhances the connection strength and overall stability between the receiving hopper 3 and the recycling hopper 4, improving the stability and reliability of the equipment under complex working conditions. Furthermore, the "L"-shaped support rod 5, while ensuring a lightweight structure, also allows materials spilled onto the support rod 5 to slide down the slope into the recycling hopper 4, reducing the frequency of manual cleaning of materials spilled onto the support rod 5. To prevent materials falling into the recycling hopper 4 from adhering, clumping, or clogging inside the hopper, a bin wall vibrator 6 is installed on the outer wall of the recycling hopper 4. There are four bin wall vibrators 6 installed on all four sides of the recycling hopper 4, which can vibrate all four sides of the recycling hopper 4, eliminating dead corners where materials stagnate, improving the emptying rate and flowability, and enabling the equipment to effectively cope with high-volume, long-term operation conditions.

[0037] Working principle:

[0038] When transporting asphalt production raw materials, some material will spill out of the receiving hopper 3 when the raw materials are poured into the receiving hopper 3. At this time, the recovery hopper 4, located outside the receiving hopper 3, will collect the material spilled outside the receiving hopper 3. When the material is inside the recovery hopper 4, it will slide down the inner wall of the recovery hopper 4 until it reaches the through hole 3001 on the side wall of the receiving hopper 3, and then slide back into the receiving hopper 3. Furthermore, a support structure is installed between the receiving hopper 3 and the recovery hopper 4. Material will also fall onto rod 5, and under the action of the "L"-shaped support rod 5, the material will slide down the inclined plane into the recycling hopper 4. In order to prevent material from adhering, clumping or blocking inside the recycling hopper 4, four hopper wall vibrators 6 are installed on the outer wall of the recycling hopper 4, respectively set on four different sides. By uniformly vibrating the recycling hopper 4, dead corners of material retention can be effectively eliminated, material flow and emptying rate can be improved, and the equipment can maintain a highly efficient and stable operating state under the conditions of high output and long-term continuous operation.
