Description

Technical Field

[0002] Excavator ripper, also called bucket hook or bucket, is a kind of interchangeable working device with crushing and loosening functions. It is often used in construction engineering. Excavator ripper adopts full hydraulic type to drive crushing work. Excavator ripper is generally used to excavate cracked rocks, crush frozen soil, and dig asphalt pavement. It is suitable for crushing and splitting hard soil, sub-hard stone, and weathered stone, so as to facilitate excavation and loading operations with bucket. At present, excavator ripper is mainly divided into single tooth and multi-tooth. Multi-tooth ripper currently has two or three teeth, and the loosening efficiency is higher than that of single-tooth ripper. However, the bucket hooks of multi-tooth ripper are arranged side by side, and the tooth tip cannot reach the ideal depth when entering the soil and loosening the soil. When using double hook tooth ripper for operation, different hook teeth often have different force conditions during operation. Therefore, if the double hook tooth bucket is used, it is easy to cause the force imbalance between the two hook teeth during operation, which makes the double hook tooth bucket more prone to unbalanced damage than the single hook tooth bucket. However, the conventional structure of directly adding a reinforcing column between two hook teeth will affect the operating efficiency of the hook shovel, that is, affect the depth of the hook shovel into the soil.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 As shown, the utility model provides a double-hook bucket for an excavator, which is made of steel as a whole, including a transfer part and a digging hook, wherein the transfer part is mainly used to connect the bucket with the excavation, and the digging hook is the part mainly used for hooking and shoveling when the bucket is working. The transfer part includes a transfer plate 11, a support plate 12 and a reinforcement sleeve 13, wherein the support plate 12 is fixedly connected to the upper end of the transfer plate 11, and the reinforcement sleeve 13 is fixedly connected to both sides of the support plate 12. As shown in the figure, the support plate 12 is fixedly connected to both sides of the transfer plate 11, and the reinforcement sleeve 13 on the support plate 12 can be used to conveniently and quickly connect or disassemble the bucket with the excavator. The digging hooks include two and are respectively connected to the two sides of the lower end of the adapter plate 11 to form a double hook bucket. The digging hook includes a rear hook 21, a middle hook 22 and a front hook 23. The rear hook 21, the middle hook 22 and the front hook 23 are connected in sequence and the front hook 23 is in a certain arc-shaped structure. The specific rear hook 21, the middle hook 22 and the front hook 23 are cut and formed by integral steel plates, which is more conducive to improving their structural strength. The end of the rear hook 21 away from the middle hook 22 is fixedly connected to the adapter plate 11, and the end of the front hook 23 away from the middle hook 22 is connected to a sharp hook 24. The sharp hook 24 is the component of the bucket with the most complex force during operation and the highest structural strength requirement. Therefore, it can be fixedly connected to the front hook 23 to increase its service life. An auxiliary plate 3 is connected between the two digging hooks connected to the lower end of the adapter, and both ends of the auxiliary plate 3 are respectively connected to one end of the middle hook portion 22 of the digging hook close to the front hook portion 23, and the auxiliary plate 3 is a flat plate structure.

[0023] like Figure 3 The figure shows the position structure of the auxiliary plate 3 relative to the digging hook when viewed from the side of an excavator double-hook bucket of the utility model. In this figure, the auxiliary plate 3 is presented in a perspective manner. Figure 3The two dotted lines in the figure respectively represent the center plane of the auxiliary plate 3 and the center axis of the hook portion 24. Figure 3 θ is the angle between the axis of the pointed hook portion 24 and the center plane of the auxiliary plate 3. As shown in the figure, the front hook portion 23 is bent to one side relative to the middle hook portion 22, and the center axis of the middle hook portion 22 is a vertical line along the vertical direction. Figure 3 The angle between the axis line of the pointed hook portion 24 of the bucket shown in FIG. 2 and the axis line of the middle hook portion 22 is an obtuse angle, and the angle between the axis line of the middle hook portion 22 and the plane of the auxiliary plate 3 is an obtuse angle. The angle between the axis line of the pointed hook portion 24 and the axis line of the middle hook portion 22 is greater than the angle between the axis line of the middle hook portion 22 and the plane of the auxiliary plate 3, and the angle θ between the axis line of the pointed hook portion 24 and the center plane of the auxiliary plate 3 is an acute angle. Therefore, when using the new type of excavator double-hook bucket for operation, since it is provided with a transition part and a digging hook, wherein an auxiliary plate 3 of a flat structure is connected between the two digging hooks, and the auxiliary plate 3 is provided with a reasonable inclination angle relative to the digging hook, so that the auxiliary plate 3 of the reinforcing structure is assisted between the two digging hooks, and at the same time, due to the special angle design of the auxiliary plate 3, the overall structural strength of the bucket is guaranteed, and at the same time, the auxiliary plate 3 has a certain external drag force relative to the sharp hook part 24 when the bucket is digging, so that it is easier to remove materials during the operation of the bucket, thereby strengthening the structure of the hook-shaped bucket while also ensuring that the bucket can have good operating efficiency.

[0024] Furthermore, in order to ensure that the auxiliary plate 3 can achieve a good material removal effect, the utility model of an excavator double-hook bucket needs to ensure that the angle between the axis of the sharp hook part 24 and the plane of the auxiliary plate 3 is reasonable. In actual application, when the angle between the axis of the sharp hook part 24 and the plane of the auxiliary plate 3 is greater than 3 degrees, the material removal effect is better guaranteed during the bucket operation. Furthermore, in order to prevent the angle between the axis of the sharp hook part 24 and the plane of the auxiliary plate 3 from being too large, thereby affecting the normal operation efficiency of the bucket, the utility model of an excavator double-hook bucket needs to control the maximum value of the angle between the axis of the sharp hook part 24 and the plane of the auxiliary plate 3. In the application process, when the angle between the axis of the sharp hook part 24 and the plane of the auxiliary plate 3 is less than 10 degrees, it can still ensure a better operation effect. When the angle between the axis of the sharp hook part 24 and the plane of the auxiliary plate 3 exceeds 10 degrees, it will seriously affect the operation efficiency of the bucket.

[0025] like Figure 4As shown, further, the utility model is an excavator double hook bucket, in order to better ensure the material removal effect of the auxiliary plate 3 during the bucket operation, the auxiliary plate 3 includes a plate body 31 and a plate tooth 32 connected to one end of the plate body 31, the plate body 31 is a rectangular plate structure, the plate tooth 32 is arranged on one side of the long side of the plate body 31, and the plate tooth 32 is close to the sharp hook part 24. At the same time, the length-to-width ratio of the plate body 31 is greater than 2 and less than 3, so that the plate body 31 has a better length-to-width ratio, so as to ensure that the auxiliary plate 3 plays a role in strengthening the structural strength and can also have a better effect of material removal during the bucket operation, so as to better ensure the bucket operation efficiency and its service life.

[0026] like Figures 1 to 3 As shown, further, the utility model is an excavator double hook bucket, in order to further improve the overall structural strength of the bucket, to ensure the service life of the bucket while also controlling its manufacturing cost, the rear hook portion 21 is in a V-shaped structure, the V-shaped bottom of the rear hook portion 21 is integrally formed with the middle hook portion 22, and the V-shaped upper end of the rear hook portion 21 is fixedly connected to the adapter plate 11.
