Description

Technical Field

[0001] The utility model belongs to the technical field of hoppers, in particular to an elevator hopper device capable of reducing material leakage. Background Art

[0002] Bucket elevator is a fixed mechanical conveying equipment, which is widely used in chemical, building materials, coal, grain and other industries to continuously vertically convey powdered, small granular and small block materials. Among them, the hopper is an important accessory of the bucket elevator.

[0003] At present, hoppers often have phenomena such as instantaneous large load or long-term feeding overload, which makes the hopper easily deformed (the main deformation location is at the scooping end). When the hopper is deformed, the material is very likely to leak during transportation, thus affecting the quality of the bucket elevator. At present, in order to solve the above problems, the wall thickness of the hopper is generally increased. Although it can increase the overall load capacity, the overall cost is greatly increased. Secondly, after increasing the wall thickness, the weight of the hopper itself increases, resulting in a significant increase in the load of the transmission part (such as plate chain, belt type, etc.), which will affect the service life of the transmission part.

[0004] In view of this, an elevator hopper device for reducing material leakage is proposed. Utility Model Content

[0005] The purpose of the present utility model is to provide a hopper device for an elevator that reduces material leakage in order to solve the above-mentioned problem.

[0006] The technical solution adopted by the present invention is as follows: a hoist hopper device for reducing material leakage, comprising a hopper body, wherein the hopper body has a material trough with an upper opening, a scooping end of the hopper body is provided with reinforcing ribs to prevent outward punching, and an auxiliary material trough connected to the material trough is formed between the reinforcing ribs and the hopper body.

[0007] In a preferred embodiment, the bottom wall of the hopper body is a downwardly curved arc surface.

[0008] In a preferred embodiment, the cross-section of the reinforcing rib is square, arc-shaped, triangular or other shapes, and the auxiliary material trough has the same shape as the reinforcing rib.

[0009] In a preferred embodiment, a plurality of mounting holes are symmetrically formed on the wall of the hopper body opposite to the scooping end thereof.

[0010] In a preferred embodiment, the reinforcing ribs are formed by cold stamping.

[0011] In a preferred embodiment, outwardly protruding baffles are provided on both sides of the outer wall of the scooping end of the hopper body, and a material guiding channel is formed between the baffles and the hopper body.

[0012] In a preferred embodiment, the hopper body and the baffle are made of stainless steel.

[0013] In a preferred embodiment, the width of the reinforcing rib is smaller than the width of the baffle. In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are:

[0014] 1. In the utility model, a reinforcing rib is formed at the scooping end of the hopper body by stamping equipment, which can improve the strength of the hopper body. Compared with the traditional hopper body, the overall load capacity can be increased without increasing the thickness and cost. The hopper is not prone to deformation and can reduce material leakage without affecting the normal material receiving and discharging.

[0015] 2. In the present invention, the auxiliary material trough formed by the reinforcing ribs after stamping can also increase the overall material capacity. After the subsequent material is connected, the overall material height can be reduced, thereby also playing a role in assisting the subsequent material leakage;

[0016] 3. In the present invention, a baffle is designed on the outer wall of the scooping end of the hopper body. When the hopper body rises to the highest point through the circulating transmission mechanism to throw the material, a small amount of material will be introduced into the discharge port of the bucket elevator through the material guide channel formed by the baffle and the hopper body, which can also reduce the leakage of some materials.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-4 A lifting machine hopper device for reducing material leakage includes a hopper body 1. The hopper body 1 has a material holding trough 101 with an upper opening. The scooping end of the hopper body 1 is prevented from being stamped outward to form a reinforcing rib 3. The reinforcing rib 3 is formed by stamping in the cold stamping direction. The scooping end of the hopper body 1 is stamped with a stamping equipment to form a reinforcing rib 3, which can improve the strength of the hopper body 1. Compared with the traditional hopper body 1, the overall load-bearing capacity can be increased without increasing the thickness and cost. The hopper is not prone to deformation, and material leakage can be reduced without affecting normal material receiving and discharging.

[0024] There is at least one reinforcing rib 3. When there is one, the reinforcing rib 3 is located in the middle of the scooping end. When there are multiple reinforcing ribs 3, the reinforcing ribs 3 are arranged at equal intervals at the scooping end.

[0025] It can be seen that at least one reinforcing rib 1 can be stamped out on the bottom wall and any side wall of the hopper body 1 to further increase the overall strength.

[0026] Furthermore, an auxiliary material trough 301 connected to the material trough 101 is formed between the reinforcing rib 3 and the hopper body 1. The auxiliary material trough 301 formed by the reinforcing rib 3 after stamping can also additionally increase the overall material holding capacity. After subsequent material connection, the overall material height can be reduced, thereby also playing a role in assisting subsequent material leakage.

[0027] Please refer to Figure 4 As shown, when the hopper body 1 receives materials by digging, the upper side of the reinforcing rib 3 is a conical surface, and the inner end surface of the top of the conical surface is flush with the inner wall of the scooping end of the hopper body 1, which ensures the strength of the hopper body 1 while not affecting the normal digging quality.

[0028] Furthermore, the bottom wall of the hopper body 1 is a downwardly curved arc surface. After the above design, no angle that is easy to accumulate material will be formed inside the hopper body 1, so that the hopper can discharge and throw materials cleanly without material return.

[0029] Furthermore, the cross section of the reinforcing rib 3 is square, arc-shaped, triangular or other shapes, and the auxiliary material trough 301 has the same shape as the reinforcing rib 3 .

[0030] Furthermore, a plurality of mounting holes 2 are symmetrically provided on the wall surface of the hopper body 1 opposite to the scooping end thereof, and the hopper body 1 can be connected to the circulating transmission structure (not shown) of the bucket elevator by bolts (not shown) through the mounting holes 2 .

[0031] The connection between the hopper body 1 and the circulating transmission structure has been realized in the prior art and will not be elaborated here in detail.

[0032] Furthermore, outwardly protruding baffles 4 are provided on both sides of the outer wall of the scooping end of the hopper body 1, and a material guide channel is formed between the baffle 4 and the hopper body 1. The width of the reinforcing rib 3 is smaller than the width of the baffle 4. The baffle 4 is designed on the outer wall of the scooping end of the hopper body 1. When the hopper body 1 rises to the highest point through the circulating transmission mechanism (not shown in the figure) to throw the material, a small amount of material will be introduced into the discharge port of the bucket elevator (not shown in the figure) through the material guide channel formed by the baffle 4 and the hopper body 1, which can also reduce the leakage of some materials.

[0033] Furthermore, the hopper body 1 and the baffle 4 are made of stainless steel. The hopper body 1 and the baffle 4 can also be made of other high-strength and corrosion-resistant materials, which will not be elaborated here.

[0034] To sum up, the scooping end of the hopper body 1 is punched with a reinforcing rib 3 by a stamping device, which can improve the strength of the hopper body 1. Compared with the traditional hopper body 1, the overall load-bearing capacity can be improved without increasing the thickness and cost, and the hopper is not prone to deformation. The leakage of materials can be reduced without affecting the normal material receiving and discharging. At the same time, the auxiliary material trough 301 formed by the reinforcing rib 1 after stamping can also additionally increase a part of the overall material holding capacity. After subsequent material receiving, the overall material height can be reduced, thereby also playing a role in assisting subsequent material leakage.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
