Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a high-temperature resistant bucket and a loader. Background Art

[0002] Loaders are widely used in construction sites, port terminals, stations, factories and other places. In some production operations, loaders sometimes need to transfer high-temperature materials and sometimes need to transfer large-volume heavy objects. For example, in a steel factory, a loader needs to cope with three very different operating conditions. First, it is to handle casting blocks with a temperature controlled below 150°C. Second, it is to load slag piled up in heaps with a temperature between 500 and 750°C. Finally, it is to transfer and load the high-temperature waste slag generated after steelmaking. These materials shine bright yellow inside and their temperature often soars above 1000°C, posing an extreme challenge to the bucket.

[0003] When the bucket of the existing technology loader is used to transfer high-temperature materials, the bucket is prone to softening of the material after being heated, resulting in deformation under stress. This reduces the service life of the bucket and seriously affects the production efficiency. At the same time, when the existing technology bucket is handling heavy objects, it often fails to lift them due to insufficient insertion force, seriously affecting the operation continuity and production efficiency. Content of the Utility Model

[0004] To solve the above problems in the existing technology, the first aspect of the utility model provides a high-temperature resistant bucket, which includes a bucket wall. On the left and right sides of the bucket wall, bucket side plates are respectively provided. At the lower edge of the bucket wall, a main cutting edge is provided. Inside the bucket wall, diversion plates are arranged at intervals along its transverse direction, and wear-resistant bottom plates are arranged between adjacent diversion plates.

[0005] Further, the diversion plates include two first diversion plates and second diversion plates with the same structure and symmetrically arranged. The wear-resistant bottom plates include a first wear-resistant bottom plate corresponding to the first diversion plate and a second wear-resistant bottom plate corresponding to the second diversion plate.

[0006] Further, heat dissipation through holes are provided on the wear-resistant bottom plates.

[0007] Further, on the outer side of the bucket side plates, side diversion plates are provided for diverting materials to both sides of the bucket.

[0008] Further, the side diversion plates include wedge-shaped plates arranged at intervals in the vertical direction.

[0009] Further, wear-resistant edge guards are provided at the connection between the bucket wall and the bucket side plates.

[0010] Further, at the front end of the main cutting edge, bucket teeth are arranged at intervals along the length direction, and a cutting blade plate detachably connected to the main cutting edge is arranged between adjacent bucket teeth.

[0011] Further, a wear-resistant side plate is fixed to the inner side of the bucket side plate. A bucket side edge is provided at the front end of the bucket side plate, and a detachable sheath is provided on the bucket side edge.

[0012] Further, the main knife plate has a wedge-shaped structure that is narrow at the front and wide at the rear.

[0013] In a second aspect of the present invention, a loader is provided, including the high-temperature resistant bucket described in any one of the above.

[0014] Compared with the prior art, the present invention mainly has the following advantages:

[0015] 1. The high-temperature resistant bucket of the present invention is provided with a diversion plate and a wear-resistant bottom plate inside the bucket wall, which improves the structural strength of the bucket and increases the wear resistance of the bucket. At the same time, the heat conducted from the high-temperature material to the bucket wall is reduced, and the deformation of the bucket after being heated can be effectively avoided.

[0016] 2. The front end of the bucket wall of the high-temperature resistant bucket of the present invention is provided with a wedge-shaped knife plate, on which bucket teeth and a detachable shovel blade are installed. The wedge-shaped knife plate greatly reduces the resistance to inserting into the material; secondly, the sharp bucket teeth have extremely strong penetration power and are easy to break large pieces of high-temperature materials such as slag, increasing the heat dissipation surface area. After the high-temperature material enters the bucket, the heat decreases quickly, extending the service life of the bucket. The detachable shovel blade protects the part between the wedge-shaped knife plate and the bucket teeth at the front end of the bucket wall, reducing the deformation of the entire bucket due to heat.

[0017] 3. The outer side of the bucket side plate of the high-temperature resistant bucket of the present invention is welded with a wear-resistant edge guard angle and a side diversion plate. The wear-resistant edge guard angle improves the strength of the bucket, and the protruding wear-resistant edge guard angle increases the heat dissipation surface area of the bucket, which is more conducive to the heat dissipation of the bucket under high-temperature working conditions. The side diversion plate is conducive to diverting the high-temperature material to both sides of the bucket when the bucket is inserted into the high-temperature slag, reducing the adhesion of the high-temperature material to the bucket, and further improving the ability of the bucket to resist deformation due to heat.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.

[0022] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] As Figure 1-2 shown, the present utility model discloses a high-temperature resistant bucket, which includes a bucket wall 1 and two bucket side plates 5. The bucket wall 1 is curved in an arc shape, and the two bucket side plates 5 are respectively welded and fixed on the left and right sides of the bucket wall 1. The bucket wall 1 and the two bucket side plates 5 form a bucket-shaped space with one end open. Preferably, the material of the side deflector 12 is NM400. The lower edge of the bucket wall 1 is provided with a main cutting plate 10, and the inner side of the bucket wall 1 is provided with deflectors 2 arranged at intervals along its transverse direction. Wear-resistant bottom plates 7 are provided between adjacent deflectors 2 and between the deflector 2 and the bucket side plate 5. The deflectors 2 and the wear-resistant bottom plates 7 improve the structural strength of the bucket and increase the wear resistance of the bucket. At the same time, the heat conducted by the high-temperature material to the bucket wall 1 is reduced, and the deformation of the bucket after being heated can be effectively avoided.

[0025] In some embodiments, the deflector 2 includes two first deflectors and second deflectors that are identical in structure and symmetrically arranged. Among them, the first deflector is attached to the upper inner side of the bucket wall 1, and the second deflector is attached to the lower inner side of the bucket wall 1. The wear-resistant bottom plate 7 includes a first wear-resistant bottom plate corresponding to the first deflector and a second wear-resistant bottom plate corresponding to the second deflector. In this embodiment, both the deflector 2 and the wear-resistant bottom plate 7 adopt a two-section structure, which reduces the bending processing difficulty and improves the material utilization rate.

[0026] Further, the deflector plate 2 is a curved long strip structure, which is fixed to the bucket wall 1 by circumferential welding. The wear-resistant bottom plate 7 is welded to the bucket wall 1, and its left and right ends are respectively welded to the deflector plate 2, or respectively welded to the deflector plate 2 and the bucket side plate 5. The joint between the wear-resistant bottom plate 7 and the deflector plate 2 is built-up welded, so that the high-strength wear-resistant bottom plate 7 and the vertical reinforcing deflector plate 2 form an integral body after welding, which can effectively reduce the thermal deformation.

[0027] In some embodiments, the wear-resistant bottom plate 7 is provided with heat dissipation through holes, and the number of heat dissipation through holes can be selected according to actual needs. The heat dissipation through holes can be circular, elliptical or racetrack-shaped. The inner side of the heat dissipation through holes is connected to the bucket wall 1 by fillet welds to increase the connection stability between the wear-resistant bottom plate 7 and the bucket wall 1, reduce the unfixed area between the wear-resistant bottom plate 7 and the bucket wall 1, and prevent the middle of the wear-resistant bottom plate 7 from bulging after being heated.

[0028] In some embodiments, a side deflector plate 12 for diverting materials to both sides of the bucket is provided on the outer side of the bucket side plate 5. The side deflector plate 12 is beneficial to diverting high-temperature materials to both sides of the bucket when the bucket is inserted into high-temperature slag, reducing the adhesion of high-temperature materials to the bucket, and further improving the ability of the bucket to resist deformation when heated. Preferably, the side deflector plate 12 includes three wedge-shaped plates, and the three wedge-shaped plates are arranged at intervals in the vertical direction. Among them, the front of the wedge-shaped plate is narrow and the rear end is wide, which is convenient for the bucket to insert into high-temperature slag.

[0029] In some embodiments, a wear-resistant edge guard angle 11 is provided at the connection between the bucket wall 1 and the bucket side plate 5, and the wear-resistant edge guard angle 11 is welded to the outer side of the bucket side plate 5 by circumferential welding. Preferably, the wear-resistant edge guard angle 11 is made of high-strength alloy cast steel F5. The wear-resistant edge guard angle 11 improves the strength of the bucket and prevents the bucket from being damaged by external impact; at the same time, the protruding wear-resistant edge guard angle 11 increases the heat dissipation surface area of the bucket, which is more conducive to the heat dissipation of the bucket under high-temperature working conditions.

[0030] In some embodiments, bucket teeth 8 are arranged at intervals along the length direction at the front end of the main cutting plate 10, and a cutting blade plate 9 detachably connected to the main cutting plate 10 is arranged between adjacent bucket teeth 8. Among them, the bucket teeth 8 are clamped on the main cutting plate 10, and the cutting blade plate 9 is fixed on the main cutting plate 10 by bolts and nuts, which is convenient for replacing the cutting blade plate 9 after wear. Preferably, the bucket teeth 8 are made of 12-series alloy, and the cutting blade plate 9 is made of high-strength alloy cast steel F5. The sharp bucket teeth 8 have extremely strong penetration power and are easy to break large pieces of high-temperature materials such as slag, increasing the heat dissipation surface area. The high-temperature materials enter the bucket and the heat is reduced quickly, which prolongs the service life of the bucket. The detachable cutting blade plate 9 protects the part between the main cutting plate 10 and the bucket teeth 8 at the front end of the bucket wall 1, reducing the thermal deformation of the whole bucket.

[0031] In some embodiments, a wear-resistant side plate 6 is fixed inside the bucket side plate 5. A bucket side edge 3 is provided at the front end of the bucket side plate 5, and a detachable sheath 4 is provided on the bucket side edge 3. Specifically, the wear-resistant side plate 6 is welded inside the bucket side plate 5, and the bucket side edge 3 is welded at the front end of the bucket side plate 5. Each bucket side edge 3 is provided with three sheaths 4 connected in sequence, and the sheath 4 is fixed to the bucket side edge 3 by a pin circlip.

[0032] In some embodiments, the main knife plate 10 is a wedge shape that is narrow at the front and wide at the rear. The wedge-shaped knife plate greatly reduces the resistance to inserting materials.

[0033] The present utility model also discloses a loader, including the above-mentioned high-temperature resistant bucket.

[0034] It can be understood that what is described in the specific embodiments is only one embodiment of the present utility model. Those skilled in the art can make various changes or equivalent replacements to these features and embodiments without departing from the spirit and scope of the present utility model. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
