When cleaning branches and stem garbage, the closure force of the existing dirt cleaning machine depends on the self-weight of the rake bucket, resulting in a small closing force and the inability to effectively remove branches and garbage.
A bucket-type dust cleaning machine was designed. Through the lifting mechanism and the opening and closing mechanism, the lifting wire rope and the opening and closing wire rope are used to increase the closing force of the rake bucket to ensure that the rake bucket can effectively pull out the branch garbage. .
By increasing the closing force of the rake bucket, it can effectively remove branch garbage, avoiding the problem of the rake bucket being blocked by branches, and improving cleaning efficiency.

Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical environmental protection equipment, and in particular relates to a rake bucket type garbage cleaning machine for cleaning branch and rod garbage. Background Art
[0002] The existing garbage cleaning machines in my country's hydropower stations use mechanical and hydraulic rake buckets. Regardless of the type of rake bucket, it is a closed volume composed of a garbage insertion device and a rotating rake device, which can directly load garbage into the rake bucket. However, when branch-like garbage is inserted into the trash rack, the vertical rake bucket teeth that are descending are blocked by branch-like garbage, and the rake bucket teeth are inserted into the branches, so the rake bucket cannot go down, and the garbage accumulated in front of the trash rack cannot be removed. For this reason, it is very necessary to develop a device for pulling out branch-like devices inserted into the trash rack.
[0003] CN205012304U proposes a solution to the above problem. Based on the traditional garbage cleaning machine, the spline is designed as a detachable structure. For the scene of branch and rod garbage, the spline is removed and the branches and rods are picked up only by engaging the bucket. The disadvantage is that, similar to the traditional garbage cleaning machine, the bucket is hinged on the large frame. On the one hand, the overall weight is large, and on the other hand, the engagement of the bucket depends on the weight of the bucket itself, and the engagement force is small. If you want to increase the engagement force, you need to increase the load on the bucket, which requires the lifting mechanism itself to provide a larger lifting force. Utility Model Content

[0012] Furthermore, the end of the rake bucket 33 forms rake teeth that match the grid of the trash rack, and at least one roller 331 is provided at the end of the rake bucket 33 .
[0013] Compared with the prior art, the rake bucket mechanism of the utility model is slidably connected to the door frame, especially the rake bucket shaft extends a lifting lug in the direction of the rake bucket closing, so that when lifting, the lifting wire rope applies force to the lifting lug, causing the lifting lug to tend to rotate to a vertical state.

The ultimate purpose of setting the above angles is to ensure that "the lifting wire rope 21 applies force to the lifting ear 34, so that the lifting ear 34 tends to rotate to a vertical state. When the opening and closing bucket wire rope 22 does not apply force to the rake bucket 33, the lifting mechanism 2 simultaneously exerts an upward pulling force and a force to keep the rake bucket 33 closed through the lifting wire rope 21, so that the closing bucket buckling force is greater".

[0038] Further, as attached Figure 1 , 6 -8, steel structure bucket guide rails 11 are respectively arranged on both sides of the gantry 1, the bottom of the steel structure bucket guide rail 11 is butted with the civil construction bucket guide rail, a sliding block 31 is slidably arranged in the bucket guide rail 11, the sliding block 31 is wheel-shaped, and the sliding block 31 is rotatably connected to the bucket shaft 32 through a bearing;
[0039] Preferably, each set of rake bucket guide rails 11 can be composed of two parallel columns, the sliding block 31 can be a polygonal block, but preferably a wheel-shaped one, the diameter of the wheel-shaped sliding block 31 is 500mm~800mm, preferably 600mm, the distance between the two columns of the rake bucket guide rail 11 is 5mm~20mm larger than the diameter of the sliding block 31, and the two form a clearance fit; the distance between the sliding block 31 and the rake bucket shaft 32 is preferably as follows Figure 8 As shown in , the two are connected by a self-aligning roller bearing, and a sealing plate is arranged outside to prevent water from entering. The sealing plate is sealed to the sliding block 31 and the rake bucket shaft 32 respectively, and the sealing connection can be a sealing strip or a sealing belt.
[0040] Further, as attached Figure 6 As shown in 6.1 and 6.2, a trash rack is arranged below the gantry 1. The trash rack structure belongs to the prior art. The upper end of the trash rack abuts against the lower end of the movable flap 12. The movable flap 12 is fixedly connected to the transverse rotating shaft 13. Both ends of the rotating shaft 13 are rotatably connected to the gantry 1, and the flap 12 rotates around the rotating shaft 13. The gantry 1 is hinged to the cylinder body of the flap cylinder 14. The output end of the flap cylinder 14 is hinged to the movable flap 12. The upper end of the movable flap 12 abuts against the lower end of the closing plate 15. The closing plate 15 is fixedly connected to the gantry 1. The movable flap 12 and the closing plate 15 are preferably the same grid structure as the trash rack.
[0041] Further, as attached Figure 7 As shown in 7.1 and 7.3, the end of the rake bucket 33 forms rake teeth that match the grid of the trash rack. At least one roller 331 is provided at the end of the rake bucket 33, which is pressed on the trash rack when the bucket is closed and rolls on the trash rack to control the size of the rake teeth inserted into the trash rack.

After the rake bucket shaft 32 hits the branches, the steel wire rope stops descending due to underload; the opening and closing bucket mechanism 4 relaxes the opening and closing bucket steel wire rope 22, and the lifting mechanism 2 controls the lifting, so that the lifting lug 34 tends to rotate to a vertical state, so that the rake bucket 33 closes and lifts at the same time, and the rake teeth can pull out the branches from the bottom, and after running to the upper dead point, that is, the closing plate 15, the angle between the movable flap 12 and the horizontal plane is greater than the 40-degree dirt retention angle, and the dirt can be unloaded.
[0044] The distance from the center of the bucket shaft 32 to the center of the lifting lug 34 is a lever arm, and the tread of the sliding block 31 is a fulcrum. When the bucket 33 is closed and lifted, the lifting force loads the bucket 33 through the lever arm. When the bucket pulls out branches, the greater the bucket resistance, the greater the lifting force, and the bucket force also increases. The bucket 33 and the trash rack form a bucket container to pull out the branches and other garbage.
[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
