[0002] An excavator is a type of mechanical equipment widely used in the construction field. When performing large-scale earthmoving operations, it can quickly and efficiently remove large amounts of soil and rocks, providing basic conditions for construction projects, road construction, etc.

[0003] Since the excavated soil has a certain viscosity and there are uncertain stones in the soil, the soil and stones will get stuck in the bucket during earthwork operations. When the bucket is stuck, the excavator will turn the bucket upside down and shake it to shake out the material in the bucket. However, due to the high viscosity of the soil mixed with the stones, they adhere to the inner wall of the bucket to form a strong adhesion, and in some cases it is difficult to shake out, and manual cleaning is required, resulting in a waste of time and manpower.

[0004] Therefore, there is an urgent need to improve the anti-adhesion device of the excavator bucket to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-adhesion device for the bucket of an excavator. The drive component is started by a drive component, a protrusion and a push tooth. The protrusion moves under the action of the drive component, and the protrusion causes the push tooth to move back and forth. When the push tooth is in a normal position, the upper surface of the push tooth is flush with the inner surface of the bucket body. When the push tooth moves forward, the upper surface of the push tooth will be higher than the inner surface of the bucket body, so that the contact area between the bucket and the material in the bucket is reduced, the adhesion of the material to the inner surface of the bucket is reduced, the material in the bucket is easier to shake out, the frequency of manual cleaning is reduced, the situation of the bucket sticking to the material is reduced, the unloading time can be shortened, the working cycle speed of the excavator is increased, and the overall operating efficiency is improved.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figure 1-Figure 5 As shown, the excavator bucket anti-adhesion device provided by this embodiment includes a bucket body 1, multiple push teeth 2 and a protrusion 3. The bottom surface of the bucket body 1 is provided with a tooth groove 4, and the end of the tooth groove 4 is provided with a tooth hole 5. The push teeth 2 are inserted into the bucket body 1 from the tooth hole 5, and the push teeth 2 are slidably connected to the tooth groove 4. The ends of the multiple push teeth 2 are commonly connected to a mounting base 6, and the push teeth 2 slide back and forth in the tooth groove 4. Side wing plates 7 are provided on both sides of the back side of the bucket body 1. The side wing plates 7 are provided with a second slide groove 12 on the surface close to the mounting base 6. The mounting base 6 is provided with a slider 13 on the surface close to the side wing plates 7. The slider 13 is long and slides slightly in the No. 2 slide groove 12. The No. 2 slide groove 12 is parallel to the direction of the tooth groove 4. When the mounting base 6 slides along the No. 2 slide groove 12, the mounting base 6 drives the push teeth 2 to slide along the tooth groove 4. Driven by the mounting base 6, the multiple push teeth 2 move synchronously.

[0025] Such as Figure 2 as well as Figure 3 As shown, a driving assembly 9 for driving the bump 3 is fixedly installed on the back of the bucket body 1. The bump 3 moves under the action of the driving assembly 9. The driving assembly 9 includes: a double-headed motor 901, a left screw rod 902, a right screw rod 903 and two nut seats 904. The double-headed motor 901 is fixedly connected to the mounting plate 8, and the nut seat 904 is fixedly connected to the bump 3. The left screw rod 902 and the right screw rod 903 are fixedly connected to the two output shafts of the double-headed motor 901 respectively. Two guide rods 11 are provided on both sides of the double-headed motor 901. The guide rod 11 passes through the bump 3. Both ends of the guide rod 11 are fixedly connected to the mounting plate 8. The mounting base 6 is provided with a No. 1 slide groove 10, and the protrusion 3 is inserted into the No. 1 slide groove 10. The No. 1 slide groove 10 and the screw rod have an inclination angle, and the guide rod 11 guides the protrusion 3. The double-headed motor 901 is started, and the double-headed motor 901 drives the left screw rod 902 and the right screw rod 903 to rotate. The wire of the left screw rod 902 is left-handed, and the wire of the right screw rod 903 is right-handed. One motor drives the two protrusions 3 to move inward or outward at the same time. When the protrusion 3 moves along the screw rod, the protrusion 3 slides in the No. 1 slide groove 10 and pushes the mounting base 6 to move at the same time. The mounting base 6 is pushed by the two protrusions 3 on both sides at the same time to make the movement of the mounting base 6 more stable.

[0026] like Figure 2 、 Figure 3 as well as Figure 5 As shown, when the mounting base 6 moves forward and backward, it drives the push teeth 2 to move. When the push teeth 2 are in the normal position, the upper surface of the push teeth 2 is flush with the inner surface of the bucket body 1, and the inner surface of the push teeth 2 is tilted. When the push teeth 2 move forward, the upper surface of the push teeth 2 is higher than the inner surface of the bucket. The push teeth 2 push the objects in the bucket forward and upward, reducing the contact area between the soil and the inside of the bucket, thereby making it easier to shake out the objects in the bucket. At the same time, the forward-extending push teeth 2 are inserted between the multiple teeth of the bucket body 1 to clean the adhesions between the teeth, reducing the frequency of manual cleaning, reducing the situation of material adhesion in the bucket, shortening the unloading time, and increasing the working cycle speed of the excavator, thereby improving the overall operating efficiency.

[0027] Further, such as Figure 1 as well as Figure 4As shown, a protective shell 15 is provided on the back of the bucket body 1, and the protective shell 15 is connected to the bucket body 1 by bolts. The protective shell 15 is the appearance surface of the back of the bucket body 1, which protects the equipment on the back of the bucket body 1. At the same time, the mounting plate 8 for mounting the drive assembly 9 is connected to the protective shell 15 by the same set of bolts. After the bolts for mounting the protective shell 15 are removed, the drive assembly 9 can be removed together with the mounting plate 8, which is convenient for disassembly and assembly of the drive assembly 9. A groove 16 is provided on the side of the mounting base 6 close to the push tooth 2, and a tooth 17 is provided on the end of the push tooth 2 inserted into the mounting base 6. The tooth 17 fits in the groove 16. A fixing plate 18 is provided on the upper surface of the mounting base 6, and the fixing plate 18 is located at the tooth 1 7, the fixing plate 18 is connected to the mounting base 6 by bolts, and the single pushing tooth 2 is installed with the mounting base 6 by the locking teeth 17 and the locking groove 16. After the single pushing tooth 2 is damaged, the single pushing tooth 2 can be replaced. The fixing plate 18 is used to fix the pushing tooth 2. At the same time, one end of the No. 2 slide groove 12 is open. When it is necessary to repair the inside of the bucket, it is only necessary to remove the bolts fixing the protective shell 15 to completely take out the entire drive assembly 9, and then slide the mounting base 6 to slide the mounting base 6 and the pushing tooth 2 out as a whole, pull out the mounting base 6, and then remove the fixing plate 18 to replace the single pushing tooth 2. This design can quickly repair the bucket when there is a problem inside the bucket, reducing the time cost of bucket maintenance.

[0028] like Figure 1-Figure 5 As shown, the principle of the excavator bucket anti-adhesion device provided by this embodiment is as follows: when the mounting base 6 moves forward and backward, it drives the push teeth 2 to move. When the push teeth 2 are in the normal position, the upper surface of the push teeth 2 is flush with the inner surface of the bucket body 1, and the inner surface of the push teeth 2 is tilted. When the push teeth 2 move forward, the upper surface of the push teeth 2 is higher than the inner surface of the bucket. The push teeth 2 push the objects in the bucket forward and upward, reducing the contact area between the soil and the inside of the bucket, thereby making it easier to shake out the objects in the bucket. At the same time, the forward-extending push teeth 2 are inserted between the multiple teeth of the bucket body 1 to clean the adhesions between the teeth, reducing the frequency of manual cleaning, reducing the situation of bucket adhesion of materials, shortening the unloading time, and increasing the working cycle speed of the excavator, thereby improving the overall operating efficiency.

[0029] The protective shell 15 is the appearance surface of the back of the bucket body 1, which protects the equipment on the back of the bucket body 1. At the same time, the mounting plate 8 for installing the drive assembly 9 is connected to the protective shell 15 by the same set of bolts. After the bolts for installing the protective shell 15 are removed, the drive assembly 9 can be removed together with the mounting plate 8, which is convenient for disassembly and assembly of the drive assembly 9. The fixing plate 18 is used to fix the push tooth 2. At the same time, one end of the No. 2 slide groove 12 is open. When it is necessary to repair the inside of the bucket, it is only necessary to remove the bolts fixing the protective shell 15 to completely take out the entire drive assembly 9, and then slide the mounting base 6 to slide the mounting base 6 and the push tooth 2 out as a whole, pull out the mounting base 6, and then remove the fixing plate 18 to replace a single push tooth 2. This design can quickly repair the bucket when there is a problem inside the bucket, reducing the time cost of bucket maintenance.
