Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing equipment, in particular to a strong impact lower hopper used in mines. Background Art

[0002] The existing material discharge method in the mining area is that concrete and other materials directly enter the concrete tanker through the discharge pipe. Because concrete and other materials fall through the discharge pipe at a fast speed, have a large impact force, and cannot store materials, the tanker is frequently damaged and frequently repaired, which seriously affects daily production and has high maintenance costs.

[0003] The existing material discharge method in the mining area is that concrete and other materials directly enter the concrete tanker through the discharge pipe, and the concrete and other materials are transported to the designated location by the concrete tanker. Because concrete and other materials fall through the discharge pipe at a fast speed and have a large impact force, the materials cannot be stored; and some dry materials are discharged with large dust, which affects environmental protection.

[0004] Therefore, a receiving hopper capable of storing materials is now needed in the mine, and the materials are received by a bucket car, and then transported to the use site, and the material is unloaded by a unloading hopper. The existing technology cannot control the storage of materials and the unloading speed of materials. Utility Model Content

[0027] The following is a clear and complete description of the technical scheme in the embodiment of the utility model in combination with the drawings and embodiments. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] See also Figure 1-3 The utility model is a strong impact hopper for mines, which comprises:

[0030] The device comprises a hopper body 1 and a control valve 2 disposed at a discharge port 15 at the bottom thereof; the hopper body 1 is the main part of the entire device and is responsible for containing and temporarily storing materials; a control valve 2 is disposed at the discharge port 15 at the bottom thereof to accurately control the opening size of the valve 2, thereby ensuring that materials can be discharged at a predetermined speed and amount, thereby meeting production requirements;

[0031] In order to reduce the impact and damage to the lower hopper, it also includes: a buffer mechanism 3, which includes a buffer hopper 31 and a support assembly 32; one end of the support assembly 32 is fixedly connected to the inner wall at the bottom end of the lower hopper body 1, and the other end is fixedly connected to the lower end of the buffer hopper 31. The buffer hopper 31 and the support assembly 32 work together to mitigate the impact of the material.

[0032] In the present application, when the material enters the buffer hopper 31 from the lower hopper body 1, the buffer hopper 31 can effectively disperse and mitigate the impact force generated when the material falls through its structure and material properties, thereby protecting the concrete tank truck and other related equipment from damage.

[0033] It should be further explained that the material enters the buffer hopper 31 through the discharge pipe. After it is filled, the excess material can fall into the hopper from all sides, thereby reducing the strong impact of the material on the concrete tank truck, so as to increase the service life of the receiving truck; at the same time, the excess material can be stored in the discharge hopper to meet the production reserve and improve production efficiency.

[0034] See also Figure 2 The support assembly 32 includes a plurality of support plates 33, which are staggeredly arranged at the base below the buffer bucket 31 and fixedly connected to the bucket wall of the lower hopper body 1; not only the stability and bearing capacity of the entire structure are enhanced, but also the impact force generated when the material falls can be effectively dispersed;

[0035] The gap between the two support plates 33 is a material discharge channel 34, which ensures that the material can be discharged from the buffer bucket 31 smoothly, avoiding blockage and backlog.

[0036] In some specific embodiments, see Figure 2 The buffer bucket 31 is hollow and has a larger upper portion and a smaller lower portion. A partition plate 35 is provided near the top wall of the buffer bucket 31. The bottom end of the buffer bucket 31 is fixedly connected to a base.

[0037] The present application effectively mitigates the impact of materials on the concrete tank truck through the design of the buffer mechanism 3, thereby extending the service life of the equipment.

[0038] The shape of the buffer bucket 31 is a hollow shape with a large top and a small bottom, which helps the material to be evenly distributed in the buffer bucket 31 and slows down the speed of the material falling. A partition 35 is set near the top wall of the buffer bucket 31, which further increases the residence time of the material in the buffer bucket 31, thereby more effectively dispersing and slowing down the impact force. The bottom end of the buffer bucket 31 is fixedly connected to the base, ensuring the stability of the entire buffer mechanism 3.

[0039] See also Figure 3 The lower hopper body 1 includes a hopper body 11 and a hopper body 2 12; wherein:

[0040] The bucket body 11 is a rectangular bucket, and the bucket body 2 12 is a funnel shape that is larger at the top and smaller at the bottom.

[0041] Specifically, the lower hopper body 1 is composed of two parts: a hopper body 11 and a hopper body 2 12. The hopper body 11 is designed as a rectangular hopper, which is conducive to the temporary storage and uniform distribution of materials. The hopper body 2 12 is designed as a funnel with a large top and a small bottom, which helps the materials to flow smoothly into the buffer hopper 31, and also facilitates the flow and discharge of materials in the hopper body.

[0042] Furthermore, one end of the control valve 2 is connected to the hydraulic rod 14, and the other end is connected to the opening and closing size of the door body 13 at the discharge port 15, so that the material discharge speed can be accurately adjusted according to production needs, thereby improving production efficiency. At the same time, the control method of the hydraulic rod 14 is also more flexible and reliable, ensuring the stability and safety of the entire material discharge process.

[0043] It should be further explained that water can be added to the hopper during specific use to achieve dust reduction and dust removal, so as to achieve the purpose of environmental protection; by adding water to the hopper, when the material falls and contacts with the water, the dust will be effectively adsorbed and settled, thereby greatly reducing the flying of dust. This design is not only simple and easy to implement, but also has significant effects. It can significantly improve the working environment and protect the health of workers, and it also meets the environmental protection requirements of modern industrial production.

[0044] The present invention is further described above in conjunction with the embodiments, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
