[0039] In a typical implementation of the present invention, Figure 1-Figure 5 As shown, a concrete self-unloading bucket is proposed, which includes a bucket body, a flap device 4 and a blade scraper device 5.
[0040] Among them, Figure 2 As shown, the bucket body is an arc-shaped opening structure, which is composed of an arc-shaped bottom plate 301, a vertical plate 302, a reinforcing rib 303, a flap shaft seat 304, a fixed door 305, a lower flange 306, a bearing box 307 and a forklift operating shaft seat 308. The two sides of the arc-shaped bottom plate 301 are fixedly connected to the vertical plate 302 to form an open bucket-shaped structure; a fixed door 305 is set at the opening of the bucket body, and the fixed door 305 is connected to the arc-shaped bottom plate 301 and the vertical plate 302. The fixed door 305 blocks the opening part of the bucket body, and the fixed door 305 is provided with a material port 309 to cooperate with the flap device 4; the reinforcing rib 303 is fixedly set on the side of the vertical plate 302. A lower flange 306 is set at the bottom of the arc-shaped bottom plate 301 of the bucket body, and a discharge cone bucket 6 can be installed.
[0041] It can be understood that the fixed door can be welded to the bucket body, and can also be installed on the bucket body with a pin shaft, and the edge sealing with a rubber strip can ensure the sealing effect of the bucket aggregate.
[0042] The vertical plates 302 on both sides of the bucket body are equipped with bearing boxes 307, which can be equipped with a rotating shaft and a blade scraper device 5. A flap shaft seat 304 is provided on the upper part of the arc bottom plate 301 of the bucket body to install a flap device 4 for controlling the cover door of the bucket. A forklift control shaft seat 308 is provided on the back of the arc bottom plate 301 of the bucket body to connect the control link of the loader to complete the posture adjustment of the bucket. When the bucket is laid flat, concrete pouring can be carried out, and when the forklift bucket is raised, concrete material can be collected into the bucket.
[0043] like Figure 3 As shown, the door flipping device 4 includes a cover door 401, a hydraulic cylinder 402, and a pin 403. The cover door 401 is correspondingly arranged at the material opening 309 of the fixed door 305. The sizes of the cover door and the fixed door match each other. The cover door can be flipped upward, that is, the cover door can be flipped upward around the matching position of the upper end and the fixed door. The cover door 401 is hinged to one end of the hydraulic cylinder 402, and the other end of the hydraulic cylinder 402 is connected to the door flipping shaft seat 304 through the pin 403. The cover door can be opened and closed to open and close the material opening of the fixed door.
[0044] The opening sizes of the fixed door and cover door can be adjusted according to actual conditions, and 1 to 2 sets of flap devices can be added if necessary.
[0045] The hydraulic cylinder 402 can be connected to the controller. The controller can be operated in the driver's cab to control the hydraulic circuit to drive the hydraulic cylinder 402 to extend and retract, thereby controlling the opening and closing of the cover door 401. When the loader 1 approaches the concrete pump truck, the bucket is lowered below the concrete pump truck discharge port, the bucket opening is facing upward, the bucket cover door 401 is opened, and the prefabricated concrete material is poured into the bucket. After the bucket is full of concrete material, the loader 1 is moved backward, the bucket is lifted, and the cover door 401 is closed to prevent the concrete material from scattering when the bucket turns. The cover door is kept open when collecting concrete material, and kept closed when unloading and pouring.
[0046] The flap device can also be opened and closed using a manual push rod. When setting it up, there should be a fixing device to keep it open when collecting concrete materials and keep it closed when unloading and pouring.
[0047] Among them, Figure 4 As shown, a blade scraper device 5 is provided in the bucket body, and the blade scraper device 5 includes a rod end bearing 501, a power rod shaft 502, a scraper blade 503 and a hydraulic motor drive device. The two ends of the power rod shaft 502 are connected to two opposite vertical plates 302. Specifically, rod end bearings 501 are provided at both ends of the power rod shaft 502, and the rod end bearings 501 are connected to the bearing box 307. Two sections of scraper blades 503 are axially provided on the power rod shaft 502. The scraper blades 503 are designed according to the bucket. The scraper blades 503 are spiral blades, and are axially fixed on the power rod shaft 502 using multiple sets of steel keys.
[0048] The two scraper blades 503 on the power rod shaft 502 are symmetrically arranged along the axial center of the power rod shaft 502. The two scraper blades 503 rotate in opposite directions. When the power rod shaft 502 rotates in both directions, the concrete material can be pushed to disperse to both sides or to concentrate in the middle.
[0049] The power rod shaft 502 is connected to the hydraulic motor drive device and driven by the hydraulic motor drive device to rotate in both positive and negative directions. When the power rod shaft 502 rotates in the reverse direction, the scraper blades 503 can push the concrete material to both sides of the bucket. When the power rod shaft 502 rotates in the forward direction, the scraper blades 503 push the concrete material from both sides to the middle to the front of the bucket, and the concrete material falls from the discharge cone bucket 6 into the hole of the cast-in-place pile to be poured.
[0050] The bottom of the bucket body is provided with a discharge cone 6 for discharging. A discharge port 310 is provided at the middle of the bottom of the arc bottom plate 301 of the bucket body, and the discharge cone 6 is installed corresponding to the bottom of the discharge port 310 of the bucket body.
[0051] like Figure 5As shown, the discharge cone bucket 6 is a conical opening structure installed in the middle of the bottom of the bucket body.

[0052] A reinforcement flange 602 is provided on the top of the conical bucket body 601 and is connected to the lower flange 306 of the bucket body.
[0053] A rotating partition 603 is arranged between the conical bucket body 601 and the bottom of the arc bottom plate 301 of the bucket body. The rotating partition can be inserted when concrete is being collected to block the unloading, and the partition can be pulled out when unloading.
[0054] It can be understood that the unloading cone bucket 6 is designed according to the properties of concrete such as strength, slump, and workability. The opening size and height can be adjusted according to the concrete properties, which can control the pouring speed of concrete and facilitate the construction operation of on-site photovoltaic civil engineering bored piles.
[0055] In a possible implementation scheme, the discharge cone bucket can be connected to a flexible hose and connected to the casting hole to reduce the height difference of the concrete from the discharge cone bucket outlet to the casting hole, thereby avoiding the precipitation and separation of aggregates and affecting the casting quality.
[0056] In another typical implementation of the present invention, Figure 6 As shown, a loader is proposed, which includes a body 1, the body 1 is connected to the bucket 3 as described above, the body is provided with a corresponding fixing structure to fix the bucket, and the connection between the body and the bucket adopts the existing technology, which will not be repeated here.
[0057] The machine body 1 is provided with a corresponding driver's cab, and the machine body 1 is also fixedly provided with a hydraulic motor 2 to provide hydraulic power for the door-opening device 4 and the blade scraper device 5. The power transmission thereof adopts the existing technology, which will not be described in detail here.
[0058] Loaders have the advantages of good mobility and easy operation, and can reach construction sites that concrete mixer trucks cannot reach. They are particularly suitable for construction operations in special landforms such as mountain photovoltaics. Through the hydraulic control of the door-opening device, blade scraper device, etc., the door can be opened automatically, and the mixing and transportation can be automatic, reducing manual work, and precast concrete can be transported to special construction locations, improving the quality of commercial concrete pouring construction.
[0059] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes.
