Description

Digging bucket

Technical Field

The application relates to the field of excavating and transporting mechanical equipment, in particular to an excavator bucket.

Background

The stone mine meets large stones which cannot be shocked by common machinery in the production process, the stones are dozens of tons as small as ten tons, and hundreds of tons as large as hundreds of tons, and the small transfer equipment such as a forklift cannot transfer the stones with large weight. Consequently, the stone is often shifted the stone to the on-the-spot direct use excavator of stone material exploitation, because the scraper bowl of traditional excavator relies on the scraper bowl to come the splendid attire sand and soil owing to needs, in order to improve the work efficiency of excavator, the hopper type often designs for the bottom plate is shorter, the great shape of contained angle between bottom plate and the curb plate, with the capacity of increase scraper bowl, then this kind of excavator is when being used for the stone material exploitation, be difficult to insert in the gap between the stone material, be difficult for digging out the stone material, and because the surface area of stone material is great, the scraper bowl of excavator can not place the stone material is stable, very easily cause the stone material to drop and lead to damaging or breakage.

SUMMERY OF THE UTILITY MODEL

In order to solve the traditional excavator scraper bowl that prior art exists and be difficult for digging out the stone material and can not be stable place the great stone of surface area, and lead to it to cause the problem that the stone material damaged easily when the stone material is mined on-the-spot to be used, this application provides an excavator scraper bowl suitable for stone material mining.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

a bucket of an excavator comprises an open bucket body, wherein one end of the bucket body is in transmission connection with an external mechanical structure, and bucket teeth are arranged on the open end far away from a connecting end; the hopper body is provided with a bottom end surface convenient for contacting the ground to slide and drag heavy objects at the back side of the opening; the side surface of the bucket body is in a triangle-like shape, and the inner angle of the side surface close to one end of the bucket tooth is less than 35 degrees.

No matter traditional excavator scraper bowl is earth bucket or rock fill, and the appearance all is more close semicircular structure, and its function uses the excavation as the owner, and the great stone of surface area can not be picked up and the device with the arc profile of scraper bowl itself. And because the restriction of scraper bowl semi-circular structure, when separation stone and ore body, can only pry the stone with the bucket tooth of scraper bowl tip, on the one hand the stone is pried open and falls the time and easily breaks down, on the other hand this kind of scraper bowl is weight injection in process of production is light quantization, often the bucket body of scraper bowl adopts thinner steel sheet to support, the material that bucket tooth use intensity is bigger, cause the wearing and tearing of bucket tooth and the stress of bucket tooth and bucket body junction great when priing open the stone, and all the other positions unnecessary are tired. Then, the stone is directly picked up and transferred by the bucket after falling down, but the stone with larger surface area cannot be picked up because the opening of the bucket is smaller, and the contour line of the opening is also a curve with larger curvature, so that the stone is easy to slip off and damage because the stone is unstable to place.

According to the scheme, the triangular side plates are adopted in the bucket body of the bucket, and due to the fact that the bottom plate is matched with the side plates, the side view of the whole bucket is close to a triangle, the curvature of the bottom surface of the bucket is small and tends to be linear, on one hand, the bucket can gradually penetrate into gaps in the process of prying off stones, and finally, the bucket has a large contact area with the stones and digs out the stones, so that the situation that the stones are broken in the process of stone mining is reduced to the maximum extent, and the loss of bucket teeth is reduced; the same nearly straight line form of the last edge line of on the other hand curb plate, when placing the stone, have great area of contact between scraper bowl and the stone, and the shape of scraper bowl makes it to form heavy lever for the stone material is placed and is transported more stably.

Simultaneously, restricted the interior angle of curb plate in this scheme, the contained angle that is close to bucket tooth one end is less, then the scraper bowl can more when digging out the stone comparatively mild deepen gradually in the gap between stone and the ore body, make the ore body keep away from gradually, finally is dug out and adjusts scraper bowl angle and shifts the stone, avoids the too big action of prying open the stone that produces and traditional excavator scraper bowl the same of lever. It should be noted that, in order to ensure that the bucket can hold heavy stones, the inner angle of the side plate near one end of the bucket tooth also cannot be too small, when the inner angle is small, in order to ensure the strength of the bucket, the total length of the bottom edge of the bucket body needs to be extended, but the too long bottom edge affects the strength of the bucket due to the limitation of material strength, and the overall weight of the bucket is increased, and if the strength limitation caused by the too long bottom edge is balanced by adding a reinforcing rib and the like, the structural complexity and the total weight of the bucket are also increased, therefore, preferably, the minimum inner angle of the side plate near one end of the bucket tooth is not lower than 20 degrees. Furthermore, since the bucket in the present application is primarily used for stone extraction, the stones are often placed directly on the bucket, rather than being held in the bucket as with gravel and sand, and therefore the cavity volume of the bucket has a limited effect on stone extraction and transfer.

Further, the side of the bucket body includes two long sides and a short side, wherein the long side plane is the bottom terminal surface of the bucket body and the uncovered place face. Make the bucket body be similar acute angle triangle's structure through the restriction to long limit and minor face in this scheme, the bottom terminal surface is favorable to placing the stone on the scraper bowl for long limit and increases the contact on bucket body bottom surface and ground when dragging the scraper bowl for ground provides bigger holding power for the scraper bowl. The long edge of the opening can increase the contact area with the stone, and is beneficial to stably placing the stone with larger surface area.

Further, the bottom plate is from last to including installation department, flexion and smooth portion down, installation department and otic placode fixed connection, the smooth portion is kept away from the one end installation bucket tooth of flexion, the department of buckling of flexion is equipped with the reinforcement angle that is used for the thickening and reduces the angle of buckling. Because the bucket body of scraper bowl is close triangle-shaped in this application, in order to avoid the too big smooth portion atress that leads to of the angle that the flexion is buckled when great, the stress concentration of the department of buckling causes the bucket body to warp or tired, the department of buckling at the flexion sets up the angle of reinforcement in this scheme, make the edgewise view, form the bottom plate and buckle twice again and transition to smooth portion from the flexion, because the smooth transition of department of buckling of scraper bowl inner space, be different from twice the buckling of surface, the structure of strengthening the thickening of angle department has then been formed, the intensity of the department of buckling has then been strengthened to the thickening here, reduce deformation or fatigue that stress concentration caused.

Furthermore, the outer bottom surface of the smooth part is an arc surface with the circle center above the bottom plate. The cambered surface arranged on the outer bottom surface of the smooth part in the scheme refers to a cambered surface on the basis that the overall shape of the bucket is similar to a triangular shape, and the curvature of the cambered surface is smaller. Because when digging out the stone, be with the upper edge and the stone contact of curb plate, the outer bottom surface and the ore body contact of smooth portion, go deep into the scraper bowl gradually and push away the ore body with the stone between the clearance of stone and ore body, the smooth portion of cambered surface shape makes and applies the impetus constantly change to the thrust of bottom plate direction from the ore body, avoids the wearing and tearing that the bottom plate stress point is single to cause. In addition, the direction of the thrust is the normal direction of the cambered surface, and the direction of the thrust is changed along with the change of the acting point, so that the bucket can dig out the stone and generate a small action of prying the stone, labor can be saved, and the efficiency of digging out the stone can be improved. In addition, the cambered surface of the bottom facilitates that when the bucket and stones above the bucket are dragged, an operator controls the contact area of the ground and the bottom surface of the bucket body by controlling the depth of the bottom surface of the bucket body penetrating into soil, so that the supporting force of the ground to the bucket body and the resistance caused by dynamic friction are controlled.

Further, the last edge line of curb plate is the camber line, just the intersection line of curb plate and bottom plate junction with the last edge line extends to the direction of dipper tooth and coincides and is tangent at the tip of dipper tooth with the contour line of dipper tooth.

Furthermore, a reinforcing plate used for being connected with the bucket teeth is fixedly installed at one end, close to the bucket teeth, of the bottom surface of the bottom plate.

The beneficial effect of this application is:

(1) the scraper bucket provided by the application can have a larger contact area with the stone blocks and dig out the stone blocks, so that the condition of stone block breakage in the process of stone block mining is reduced to the greatest extent, and the loss of the bucket teeth is reduced;

(2) the last edge line of curb plate is close the straight line form, when placing the stone, has great area of contact between scraper bowl and the stone for the stone material is placed and is transported more stably.

Example 1:

1-5, the excavator bucket comprises a bucket body 2 with an opening, one end of the bucket body 2 is in transmission connection with an external mechanical structure, and bucket teeth 6 are arranged on the opening and far away from a connecting end; the hopper body 2 is provided with a bottom end surface convenient for contacting the ground to slide and drag heavy objects at the back side of the opening; the side surface of the bucket body 2 is in a triangle-like shape, and the inner angle of the side surface close to one end of the bucket tooth 6 is less than 35 degrees.

The working principle is as follows:

the excavator bucket in this application is used for the exploitation and the transportation of stone material, passes through otic placode 3 on the bucket body 2 and the organism 1 swing joint of traditional excavator during the use, as shown in fig. 1, controls the cantilever with organism 1 to the rotation of control bucket. When the stone is mined, firstly, an ore body of a mining area is cut into blocks by utilizing cutting equipment, the square amount of the blocks is dozens of hundreds, the gap between the blocks and the ore body is small and often does not exceed 20cm, when the stone mining area is used, the bucket teeth 6 are firstly inserted into the gap, then the bucket body 2 is gradually inserted into the gap between the blocks and the ore body, the edge of the side plate 4 is firstly kept in contact with the blocks as far as possible in the insertion process, the blocks are excavated towards the direction gradually far away from the ore body, meanwhile, the bucket is gradually rotated until the edge line at the opening (namely the upper edge line of the side plate 4) is horizontal as seen from the side surface of the bucket, then the angle of the bucket is kept fixed, the bottom surface of the bucket body 2 is contacted with the ground, the supporting force from the ground is obtained, then, the bucket is dragged to integrally transfer the blocks, or the bucket is directly lifted to transfer the blocks.

It is worth mentioning that, different from the existing excavator bucket, in order to increase the volume and set the arc radius of the bucket to be higher in curvature and deeper, the bucket in the present application can be set longer in the smoothing part 503 of the bottom plate 5 in order to provide more points of support and to be easier to get deep into the stone gap when the bucket lifts the stone, and since the bucket is overall close to a triangle, the total height is limited, and the inner angle size of the side plate 4 close to one end of the bucket tooth 6 also affects the length of the smoothing part 503 to a certain extent.

In addition, the further restriction of going forward to the interior angle of curb plate 4 in this scheme, the contained angle that is close to 6 one ends of bucket tooth is less, then the scraper bowl can more when digging out the stone comparatively mild deepen gradually in the gap between stone and the ore body, makes the ore body be kept away from gradually to the stone, finally is dug out and adjusts the scraper bowl angle and shifts the stone, avoids the too big action of prying open the stone that produces and traditional excavator scraper bowl the same of lever. It should be noted that, in order to ensure that the bucket can hold heavy rocks, the inner angle of the side plate 4 near one end of the tooth 6 also cannot be too small, when the inner angle is small, in order to ensure the strength of the bucket, the total length of the smoothing portion 503 of the bucket body 2 needs to be lengthened, but when the smoothing portion 503 is too long, the strength of the bucket is affected due to the limitation of the material strength, and when the smoothing portion 503 is too long, the weight of the whole bucket is also increased, and if the strength of the smoothing portion 503 is increased by adding a reinforcing rib or the like, the structural complexity and the total weight of the bucket are also increased, therefore, preferably, the inner angle of the side plate 4 near one end of the tooth 6 is not less than 20 degrees at the minimum. Furthermore, since the bucket in the present application is primarily used for stone extraction, the stones are often placed directly on the bucket, rather than being held in the bucket as with gravel and sand, and therefore the cavity volume of the bucket has a limited effect on stone extraction and transfer.

Example 2:

this example is further optimized and defined based on example 1.

As shown in fig. 2 and 5, the side surface of the bucket body 2 includes two long sides and one short side, wherein the long side is the bottom end surface and the open side of the bucket body 2.

Make the bucket body be similar acute angle triangle's structure through the restriction to long limit and minor face in this embodiment, the contact on bottom terminal surface for long limit is favorable to placing the stone on the scraper bowl and increase bucket body bottom surface and ground when dragging the scraper bowl for ground provides bigger holding power for the scraper bowl. The long edge of the opening can increase the contact area with the stone, and is beneficial to stably placing the stone with larger surface area.

Example 3:

in this embodiment, further optimization and limitation are performed on the basis of embodiment 2.

As shown in fig. 4 and 5, the bottom plate 5 includes an installation portion 501, a bending portion and a smooth portion 503 from top to bottom, the installation portion 501 is fixedly connected with the ear plate 3, the smooth portion 503 is far away from one end of the bending portion to install the bucket tooth 6, and the bending portion of the bending portion is provided with a reinforced angle 502 for thickening and reducing the bending angle.

It should be noted that the reinforcing angle 502 is used for thickening, which means that since the inner space of the bucket is in smooth transition as in the existing bucket, the design that dead angles for accumulating sand and stones are formed at the bent part is avoided, but there is a bent part when viewed from the outer surface of the bottom plate 5, and the bent part of the bent part is not directly bent and transited to the smooth part 503, the reinforcing angle 502 is additionally provided, so that a shape that the transition from the mounting part 501 to the smooth part 503 is performed through two times of micro bending, and the extra reinforcing angle 502 is solid, which results in the increase of the thickness at the part. The thickening of the bending part strengthens the strength of the bending part and reduces the deformation or fatigue caused by stress concentration. Meanwhile, the arrangement of the strengthening angle 502 reduces the transition angle from the mounting part 501 to the smooth part 503, and avoids the excessive concentration of stress to a certain extent.

Preferably, the outer bottom surface of the smooth portion 503 is an arc surface with a center above the bottom plate 5. The side of bucket body 2 by with 5 both sides fixed connection's of bottom plate curb plate 4 constitutes, the last edge line of curb plate 4 is the arc form, just the intersection line of curb plate 4 and 5 junctions of bottom plate with the last edge line extends to the direction of bucket tooth 6 and coincides and is tangent at the tip of bucket tooth 6 with the contour line of bucket tooth 6. The arc surface formed on the outer bottom surface of the smooth portion 503 is an arc surface on the basis of not changing the overall shape of the bucket like a triangle, and the curvature of the arc surface is small. Because when digging out the stone, be with the top edge and the stone contact of curb plate 4, the outer bottom surface and the ore body contact of smooth portion 503, deepen the scraper bowl into the stone gradually and push away from the ore body, the smooth portion 503 of cambered surface shape makes the impetus of applying the thrust of bottom plate 5 direction from the ore body constantly change, avoids the wearing and tearing that bottom plate 5 stress point is single to cause. In addition, the direction of the thrust is the normal direction of the cambered surface, and the direction of the thrust is changed along with the change of the acting point, so that the bucket can dig out the stone and generate a small action of prying the stone, labor can be saved, and the efficiency of digging out the stone can be improved. In addition, the cambered surface of the bottom facilitates that when the bucket and the stones above the bucket are dragged, an operator controls the contact area of the ground and the bottom surface of the bucket body by controlling the depth of the bottom surface of the bucket body penetrating into the soil, so that the supporting force of the ground to the bucket body and the resistance caused by friction are controlled.

Preferably, the upper edge line of curb plate is the camber line, just the intersection line of curb plate and bottom plate junction with the upper edge line extends to the direction of bucket tooth and coincides and is tangent at the tip of bucket tooth with the contour line of bucket tooth.

Example 4:

this example is further optimized and defined based on example 1.

As shown in fig. 4, a reinforcing plate 7 for connecting the tooth 6 is fixedly mounted on one end of the bottom surface of the bottom plate 5 close to the tooth 6.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
