DETAILED DESCRIPTION

[0021] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] The “top surface”, “bottom surface” and “underside” are based on the normal use state of the earth-moving bucket and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0023] like Figure 1 and 2 As shown, an earthmoving bucket capable of reducing soil adhesion comprises a bucket body 1, the front end and the end of the bucket body 1 are respectively fixedly connected with a bucket tooth plate 102 and a bucket ear 101, the width direction of the bucket body 1 is a first direction, a front side edge of the bucket tooth plate 102 is spaced apart along the first direction with a plurality of bucket teeth 104, the interior of the bucket body 1 is spaced apart along the first direction with a plurality of cables 2, the two ends of the cable 2 are respectively connected with the bucket tooth plate 102 and the end of the bucket body 1, the connecting line between the two ends of the cable 2 extends perpendicular to the first direction, and the middle part of the cable 2 hangs down to the bottom of the bucket body 1.

[0024] In the above-mentioned earth-moving bucket, the cable 2 is arranged to support the soil, leaving a gap between the soil and the bucket body 1, preventing vacuum adsorption between the soil and the bucket body 1, and reducing the contact area between the soil and the bucket body 1, thereby reducing the friction between the two. In this way, when the soil is poured out from the inside of the bucket body 1, the adhesion of the soil inside the bucket body 1 can be reduced, thereby reducing the occupation of the internal space of the bucket body 1 by the soil, improving the working efficiency of the earth-moving bucket, and reducing the weight of the earth-moving bucket, reducing the energy consumption of the equipment, and improving the stability of the equipment; at the same time, when the bucket body 1 moves, the cable 2 swings freely in the bucket body 1, and the cable 2 hits the soil adhered to the inner wall of the bucket body 1, which can further reduce the adhesion of the soil inside the bucket body 1.

[0025] In the earth-moving bucket, the cable 2 extends from the end of the bucket body 1 to the front end, covering a large range of the inner wall of the bucket, thereby improving the effect of the earth-moving bucket in preventing soil adhesion. The extension direction of the cable 2 is perpendicular to the first direction, that is, consistent with the movement direction of the soil when entering and dumping, thereby reducing the resistance of the cable 2 to the soil and reducing the adhesion of the soil inside the bucket body 1; the middle part of the cable 2 hangs down to the bottom of the bucket body 1, so that the cable 2 can be attached to the inner wall of the bucket body 1, thereby reducing the influence of the cable 2 on the amount of soil loaded in the earth-moving bucket and ensuring the working efficiency of the earth-moving bucket.

[0026] During the movement of the earth-moving bucket, the hanging part of the cable 2 can swing freely with the movement of the earth-moving bucket, so that the soil adhering to the cable 2 can be thrown off under the action of centrifugal force, reducing the adhesion of the soil on the cable 2, and the cable 2 can hit the soil adhering to the inner wall of the bucket body 1, further reducing the amount of soil adhering to the inside of the earth-moving bucket.

[0027] A further improvement is, Figure 3 As shown, a plurality of elastic blocks 201 are fixedly connected to the cable 2, and the elastic blocks 201 are evenly spaced along the extension direction of the cable 2. The elastic blocks 201 are rubber blocks, and the buffering effect of the elastic blocks 201 can reduce the wear between the cable 2 and the bucket body 1, thereby extending the service life of the earth-moving bucket; and when the earth-moving bucket shovels soil into the bucket body 1, the buffering effect of the elastic blocks 201 can also reduce the impact of the soil on the bucket body 1, further reducing the wear rate of the bucket body 1; the elastic blocks 201 are fixedly connected to the cable 2, which can prevent the elastic blocks 201 from sliding on the cable 2, ensure the uniform distribution of the elastic blocks 201 on the cable 2, and thus ensure the buffering effect of the elastic blocks 201.

[0028] A further improvement is, Figure 3 As shown, a hard impact block 202 is arranged between two adjacent elastic blocks 201, and the impact block 202 is provided with a hole for passing the cable 2, and the impact block 202 is slidably connected with the cable 2. The impact block 202 can be made of hard alloy steel, and the size of the impact block 202 is smaller than the size of the elastic block 201, so that under the support of the elastic block 201, the probability of collision between the impact block 202 and the inner wall of the bucket body 1 is reduced, and the mutual wear between the two is reduced; during the shaking process of the cable 2, the impact block 202 can impact the soil adhered to the inner wall of the bucket body 1, so that the soil is loosened and falls, and the cleaning effect of the adhered soil is improved; and the impact block 202 can slide along the cable 2, so as to increase the impact range of the impact block 202, improve the cleaning effect of the impact block on the soil, and can also clean the small soil adhered to the cable 2 during the sliding process of the impact block 202.

[0029] A further improvement is that the surface of the cable 2 is covered with a lubricating layer, which is a polytetrafluoroethylene layer. Polytetrafluoroethylene has stable chemical properties, high mechanical strength, and extremely low friction coefficient, which can reduce the friction coefficient of the cable 2 surface, thereby reducing the adhesion of mud on the cable 2 and improving the smoothness of the sliding of the impact block 202.

[0030] A further improvement is, Figure 1-3As shown, the end of the bucket body 1 and the bucket tooth plate 102 are both provided with threaded holes 103, and both ends of the cable 2 are fixedly connected with fixing rings 203, which are fixedly connected to the threaded holes 103 by bolts 4. The connection and separation between the bolts 4 and the threaded holes 103 are extremely convenient, and the connection method of the bolts 4 can greatly improve the convenience of disassembly and assembly of the cable 2, thereby improving the convenience of replacement and maintenance of the cable 2.

[0031] A further improvement is, Figure 1 As shown, a plurality of protective blocks 3 are also provided at the front edge of the bucket tooth plate 102, and each protective block 3 is staggered with each bucket tooth 104, and a fixing ring 203 connected to the bucket tooth plate 102 is located inside the protective block 3. The protective block 3 is made of hard alloy steel, and the exposed bucket tooth plate 102 between the bucket teeth can be protected by the provision of the protective block 3, so as to reduce the wear of the bucket tooth plate 102 and extend the service life of the earth moving bucket; and the protective block 3 covers the connection part between the cable 2 and the bucket tooth plate 102, so as to reduce the wear of the connection part between the cable 2 and the bucket tooth plate 102 during the earth moving bucket digging process, improve the firmness of the cable 2 installation, and thus ensure the effect of preventing the earth moving bucket from adhering to the soil.

[0032] A further improvement is, Figure 4 As shown, the protection block 3 has a plug-in slot 301 for the front edge of the bucket tooth plate 102 to enter, a countersunk hole 303 is provided on the inner bottom wall of the plug-in slot 301, and a limit slot 302 for accommodating the fixing ring 203 is provided on the inner top of the plug-in slot 301, and the bolt 4 passes through the countersunk hole 303, the threaded hole 103 and the fixing ring 203 in sequence. The bolt 4 is connected with the threaded hole 103 on the bucket tooth plate 102, and the protection block 3 can be fixed to the bucket tooth plate 102 by the bolt 4, and the fixing ring 203 at the end of the cable 2 is fixed at the same time, which improves the convenience of installing the protection block 3. The setting of the countersunk hole 303 allows the head of the bolt 4 to be received in the countersunk hole 303, thereby protecting the bolt 4 and reducing the probability of damage.
