Description

Technical Field

[0001] The utility model belongs to the technical field of bucket mechanisms, and in particular relates to a bucket mechanism of a construction excavator. Background Art

[0002] Buckets are structural products, consisting of tooth seat plates, bottom plates, side plates, wall plates, ear plates, back plates, bucket ear plates, bucket ear sleeves, bucket teeth, tooth seats, guard plates or bucket angles. Buckets are generally used in light working environments such as clay excavation and sand, soil, and gravel loading. Buckets have a large bucket mouth area and a large stacking surface, so they have a high filling coefficient; they save working time and are highly efficient. When the excavator needs to excavate large sand and gravel in the water, the bucket will bring out water when digging out the sand and gravel, and at this time the water needs to be filtered out;

[0003] The related art (publication number: CN217231994U) discloses an excavator bucket for construction engineering, and the disclosed technical solution is: by adjusting four adjustment blocks, the patency of multiple water filter holes on the bucket body can be controlled, so that the water in the bucket body can flow out through the multiple water filter holes, which plays the role of automatic water filtering, so that the common three-sided sealed bucket body has the function of filtering, and at the same time does not affect the daily use of the bucket body, and increases the flexibility of the use of the bucket body;

[0004] In the above disclosed technical solutions, the following problems are found in the related technologies: in the process of digging out the silt by the bucket, since the specifications of the silt are usually relatively small, some of the silt may flow out of the outside through the water filter holes. In the process of filtering water through multiple water filter holes, the silt with a large density may cause the water filter holes to be blocked, thereby affecting the water filtering effect. In addition, there is a corresponding chute in the limiting component near the baffle. In the process of digging out the silt, the silt enters the interior and affects the use of the threaded rod, so that the fine silt is immersed in the thread, thereby affecting the use of the threaded rod. In this regard, we propose a new type of bucket mechanism for a construction excavator;

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background technology section of this application, and therefore may include prior art information that does not constitute known to ordinary technicians in the field.

[0008] In addition, the bucket mechanism of a construction excavator in the above technical solution provided by the utility model may also have the following additional technical features:

[0009] In the above technical solution, the inner cavity of the box body is symmetrically embedded with sliding rods, and the movable plate is slidably connected to the outside of the sliding rods.

[0010] The inner side wall of the collection box is symmetrically fixed with limit blocks, and the first filter screen slides between the two limit blocks.

[0011] A sealing gasket is fixedly installed on the outer side wall of the collection box in a circumferentially symmetrical manner.

[0012] The two side walls of the bucket body are rotatably connected with a rotating shaft through symmetrical mounting plates respectively, the baffle plate is sleeved on the outside of the rotating shaft, and the baffle plate is provided with a positioning bolt.

[0018] 3. The first filter can slide between the two limit blocks in an upward and downward manner, thereby ensuring the stability of the filtering process of the first filter and ensuring the sealing between the first filter and the inner walls on both sides of the collection box, thereby improving the filtering effect.

[0019] 4. During the underwater bucket digging operation, the baffle is rotated by the shaft to move the baffle away from the drain hole, and then fixed by the positioning bolts on the baffle surface.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0027] The following is a combination of specific implementation cases and attached Figure 1-3 The present invention is further described below, but the present invention is not limited to these embodiments.

[0028] Example 1

[0029] A bucket mechanism of a construction excavator, such as Figure 1-Figure 3As shown, it includes a bucket body 1, and drainage holes 14 are evenly opened on both side walls of the bucket body 1. Baffles 12 are symmetrically rotated and set on both side walls of the bucket body 1. The side walls of the bucket body 1 are provided with a collecting box 2 embedded in the inner cavity through a symmetrical connecting mechanism. A plurality of drainage holes 14 connected to the inside of the bucket body 1 are opened on the surfaces of both sides of the bucket body 1, so that water in the bucket body 1 can be discharged to the outside through the drainage holes 14. The baffles 12 that are rotated and set at the corresponding positions of the drainage holes 14 are used to cover the drainage holes 12 to prevent other materials from leaking out when being dug. The collecting box 2 corresponds to the specifications of the bucket body 1, so that the collecting box 2 is embedded in the bucket body 1, and the side walls around the collecting box 2 are all fitted and snapped on the inner surface of the bucket body 1, so that the side walls around the collecting box 2 are connected to the corresponding side walls of the bucket body 1. The walls are sealed and fitted together, that is, embedded without gaps. The inner cavity of the collection box 2 is embedded with a first filter screen 4, which is located inside the collection box 2 and close to the lower surface. The side walls of the collection box 2 are evenly provided with water outlet holes 8, and a plurality of water outlet holes 8 connected to the inside are successively provided at the bottom of the collection box 2, so that the sewage after passing through the first filter screen 4 enters the bucket body 1 through the water outlet holes 8, and is discharged to the outside through a plurality of drainage holes 14 on both sides of the bucket body 1. The side walls of the collection box 2 are symmetrically fixed with a box body 6, and the two box bodies 6 are vertically fixed to the bottom of the collection box 2 in parallel with each other. The inner cavity of the box body 6 is slidably connected with a movable plate 13, and the shape of the movable plate 13 corresponds to the inner wall of the box body 6, so that the movable plate 13 fits the inner wall of the box body 6 and slides up and down. One end of the movable rod 7 is fixedly installed on the side wall of the movable plate 13, and the other end of the movable rod 7 is fixedly installed on the side wall of the first filter screen 4. The movable rod 7 passes through the side wall of the box body 6 and the side wall of the collecting box 2 in sequence and extends to the inner cavity. One end of the two movable rods 7 are respectively fixed vertically on the surface of the movable plate 13 inside the two boxes 6, and the other ends of the two movable rods 7 are vertically fixed to the surface of the first filter screen 4 in parallel with each other. The two movable rods 7 slide in their respective through holes. The outside of the movable rod 7 is sleeved with a spring 17, and the spring 17 is movably sleeved on the outer surface of the part of the movable rod 7 located inside the box body 1, and the two ends of the spring 17 are respectively fixedly installed on the surface of the movable plate 13 and the inner wall of the upper surface of the box body 6, and the spring 17 fits in the part of the movable rod 7. The outer surface of the movable rod 7 is telescopic and slidable, and a motor 19 is fixedly installed inside the box body 6. A cam 18 is sleeved on the outside of the output shaft of the motor 19. The cam 18 fits on the side wall of the movable plate 13. The motor 19 is fixed inside the box body 6 through a motor seat. The cam 18 is fixedly sleeved on the outer surface of the output shaft of the motor 19 through the central mounting hole. The position of the motor 19 ensures that the cam 18 fits the surface of the movable plate 13. The motor 19 is electrically connected to an external power supply through a wire. When the excavator needs to excavate larger sand and gravel in the water, the collection box 2 is embedded in the bucket body 1 and fixed by the connecting mechanism on the bucket body 1, and then the baffle 12 is rotated to remove the baffle 12 from the surface of the drain hole 14, and then the motor 19 is connected to the power supply at the same time.The output shaft of the motor 19 drives the cam 18 to rotate. When the cam 18 rotates half a circle, the cam 18 pushes the movable plate 13 to move to one side, so that the movable plate 13 drives the first filter screen 4 to move to one side through the movable rod 7. At this time, the spring 17 is compressed by the movable plate 13 and generates elastic force. When the cam 18 rotates half a circle again, the cam 18 moves away from the surface of the movable plate 13. At this time, the elastic force of the spring 17 drives the movable plate 13 to move to the other side, so that the movable plate 13 drives the first filter screen 4 to move to the other side through the movable rod 7. That is, after the cam 18 rotates one circle, the first filter screen 4 The up and down vibrations are sequentially controlled by the excavator to control the bucket to dig the sand and gravel in the water, so that the sand and gravel and water enter the inside of the collection box 2 which is sealed and embedded around the bucket 1. After the sand and gravel are filtered through the first filter 4, the water enters the bottom of the collection box 2 through the first filter 4, and then flows into the bucket 1 through the water outlet 8 at the bottom of the collection box 2, and is discharged to the outside through the drainage holes 14 on both sides of the bucket 1. During the filtering process of the first filter 4, the reciprocating vibration of the first filter 4 prevents fine sand and gravel from clogging the filter holes, ensuring the fluidity of the filtered water and avoiding clogging, thereby ensuring the efficiency of the construction process.

[0030] Among them, the inner cavity of the box body 6 is symmetrically embedded with a slide rod 20, and the movable plate 13 is slidably connected to the outside of the slide rod 20. Two parallel slide rods 20 are vertically fixed inside the box body 6 and on both sides of the motor 19, so that the two ends of the slide rod 20 are respectively vertically fixed to the inner walls on both sides of the box body 6, and the movable plate 13 is movably connected to the outer surface of the slide rod 20 by opening a through hole. When the cam 18 is driven to rotate by the output shaft of the motor 19 so that the movable plate 13 drives the first filter screen 4 to reciprocate and vibrate and filter through the movable rod 7, the movable plate 13 is simultaneously attached to the outer surfaces of the two parallel slide rods 20 to slide. The stability of the moving process of the movable plate 13 is guaranteed by the two slide rods 20 to avoid position deviation, thereby ensuring the stability of the filtration process of the first filter screen 4.

[0031] It is worth mentioning that the inner wall of the collecting box 2 is symmetrically fixed with limit blocks 21, and the first filter 4 slides between the two limit blocks 21. By fixing two limit blocks 21 with inclined upper surfaces on the inner walls on both sides of the collecting box 2 and at positions corresponding to the first filter 4, the first filter 4 can slide between the two limit blocks 21 in an up and down manner, thereby ensuring the stability of the filtration process of the first filter 4, and at the same time ensuring the sealing between the first filter 4 and the inner walls on both sides of the collecting box 2, thereby improving the filtering effect.

[0032] In addition, a sealing gasket 22 is fixedly installed symmetrically on the outer wall of the collecting box 2 in the circumferential direction. The sealing gaskets 22 made of elastomeric material are fixedly installed on the outer surfaces of the four sides of the collecting box 2, so that after the collecting box 2 is embedded in the bucket body 1, the sealing gasket 22 fits against the inner wall of the bucket body 1. The elastic deformation of the sealing gasket 22 improves the sealing between the collecting box 2 and the inner wall of the bucket body 1, thereby preventing water from flowing into the gap between the collecting box 2 and the bucket body 1.

[0033] In addition, the two side walls of the bucket body 1 are rotatably connected with the rotating shaft 15 through symmetrical mounting plates 16, and the baffle 12 is sleeved on the outside of the rotating shaft 15. The baffle 12 is provided with positioning bolts, and two parallel mounting plates 16 are vertically fixedly installed on the surface of the bucket body 1 and at positions corresponding to the drainage hole 14. Mounting bearings are embedded in the opposite surfaces of the two mounting plates 16, and the two ends of the rotating shaft 15 are embedded in the inside of the two bearings. The right-angle side of the baffle 12 is fixedly installed with a sleeve so that the sleeve is fixedly sleeved on the outer surface of the rotating shaft 15. During the process of digging buckets in water, the baffle 12 is rotated by the rotating shaft 15 to remove the baffle 12 from the drainage hole 14, and then fixed by the positioning bolts on the surface of the baffle 12. During the process of digging materials, the baffle 12 is rotated to a position that fits the surface of the drainage hole 14 and is fixed by locking bolts, so that the operation process is more convenient and the baffle 12 can be adjusted according to the use environment.

[0034] The clamping seat 9 is symmetrically fixed on the side wall of the bucket body 1. The side wall of the clamping seat 9 is provided with a clamping groove. The clamping block 10 is fixedly installed on the side wall of the collection box 2 through the connecting plate 3. The side wall of the clamping seat 9 is threadedly connected with a fixing bolt 11. The position where the clamping block 10 is fixed by the connecting plate 3 corresponds to the clamping seat 9 on the side wall of the bucket body 1. In the process of embedding the collection box 2 into the bucket body 1, the collection box 2 drives the clamping block 10 to slide into the clamping groove on the surface of the clamping seat 9 on the surface of the bucket body 1 through the connecting plate 3 on the surface. After the collection box 2 is sealed and embedded in the bucket body 1, the fixing bolt 11 is turned, and the fixing bolt 11 passes through the side wall of the clamping seat 9 and enters the clamping groove and is clamped on the surface of the clamping block 10. The clamping cooperation between the clamping block 10 and the clamping groove on the surface of the clamping seat 9 makes the operation of the installation and disassembly process of the collection box 2 more convenient. The collection box 2 is installed according to the use environment, thereby bringing convenience to the construction process of relevant personnel.

[0035] A second filter 5 is embedded in the inner cavity of the collection box 2. The second filter 5 is fixedly embedded in the collection box 2 and is located above the first filter 4. The aperture of the second filter 5 is larger than the aperture of the first filter 4. When digging sand and gravel in the water, the sand and gravel are initially filtered through the second filter 5 with larger pores, and then filtered again through the first filter 4, which reduces the amount of sand and gravel filtered by the first filter 4, thereby improving the water filtration effect.

[0036] The bucket mechanism of a construction excavator of the present embodiment has the following working principle: when the excavator needs to excavate sand and gravel in the water, the collection box 2 is embedded in the bucket body 1, so that the collection box 2 drives the block 10 to slide into the card groove on the surface of the card seat 9 on the surface of the bucket body 1 through the connecting plate 3 on the surface; after the collection box 2 is sealed and embedded in the bucket body 1, the fixing bolt 11 is screwed, and the fixing bolt 11 passes through the side wall of the card seat 9 and enters the card groove and is carded on the surface of the block 10; then, the motor 19 is connected to the power supply at the same time, so that the output shaft of the motor 19 drives the cam 18 to rotate; after the cam 18 rotates half a circle, the cam 18 pushes the movable plate 13 to move to one side, so that the movable plate 13 drives the first filter screen 4 to move to one side through the movable rod 7. At this time, the spring 17 is compressed by the movable plate 13 and generates elastic force. When the cam 18 rotates half a circle again, the cam 18 moves away from the surface of the movable plate 13. At this time, the elastic force of the spring 17 is used to drive the movable plate 13 to move to the other side, so that the movable plate 13 drives the first filter screen 4 to move to the other side through the movable rod 7. That is, after the cam 18 rotates one circle, the first filter screen 4 vibrates up and down in sequence. In the process of controlling the bucket body to excavate sand and gravel in the water by the excavator, the sand and gravel and water enter the interior of the collection box 2 sealed and embedded around the bucket body 1, so that after the sand and gravel are filtered by the first filter screen 4, the water enters the bottom of the collection box 2 through the first filter screen 4, and then flows into the bucket body 1 through the water outlet hole 8 at the bottom of the collection box 2, and is discharged to the outside through the drainage holes 14 on both sides of the bucket body 1.
