[0033] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Please refer to Figures 1 to 6 , an embodiment of the present invention provides a high-efficiency flip spreader, comprising:

[0036] Spreader frame 1;

[0037] The sling inner frame 2 is arranged in the sling outer frame 1, and the middle parts of both sides thereof are rotatably connected to the sling outer frame 1 through the rotating shaft 21;

[0038] The hopper 3 is separately arranged in the inner frame 2 of the spreader;

[0039] An automatic clamping and fixing assembly 4 is provided between the sling inner frame 2 and the hopper 3 and is used for automatically clamping, fixing and separating the hopper 3 and the sling inner frame 2;

[0040] The guide assembly 5 is fixedly provided at the bottom of the sling inner frame 2 and is used for guiding the sling inner frame 2 when it is put on the hopper 3 or separated from the hopper 3;

[0041] The tilting motor 6 is arranged on one side of the sling outer frame 1 and is transmission-connected to the sling inner frame 2 via a rotating shaft 21 .

[0042] In this embodiment, at least two hoppers 3 are provided. To transport materials, the hoppers 3 are first filled, and then the crane controls the lowering of the spreader outer frame 1 and the spreader inner frame 2. Guided by the guide assembly 5, the fully loaded hopper 3 enters the spreader inner frame 2 and is secured to the spreader inner frame 2 via the automatic snap-on securing assembly 4. After the crane transports the materials to the destination, the tilting motor 6 drives the spreader inner frame 2 to tilt, which in turn tilts the hopper 3 to complete the material dumping. The hopper 3 can be tilted to any angle, ensuring clean material dumping.

[0043] During material transport, the other hopper 3 is filled. After the spreader returns, the automatic latching and fixing assembly 4 unlocks the empty hopper 3, disengaging it from the spreader inner frame 2. The fully loaded hopper 3 is then latched and fixed, allowing transport to continue. After the spreader returns, there is no need to wait for material to be loaded, achieving simultaneous material transport and loading operations, greatly improving transport efficiency.

[0044] In a preferred embodiment, if Figure 1 、 4As shown in Figure 6, the automatic clamping and fixing assembly 4 includes four reverse hooks 41 fixedly arranged on the top of the sling inner frame 2 in a rectangular distribution. The reverse hooks 41 are clamped on the top edge of the hopper 3. Transmission rods 42 are symmetrically arranged on both sides above the sling inner frame 2. A shaft rod 43 is provided at each end of the transmission rod 42. The shaft rod 43 vertically passes through the sling inner frame 2 and is rotatably connected to the sling inner frame 2 through a shaft sleeve. A connecting piece 44 is provided between the top of the shaft rod 43 and the end of the transmission rod 42. The connecting piece 4 One end of 4 is fixedly connected to the shaft 43, and the other end is rotatably connected to the transmission rod 42. The bottom end of the shaft 43 is fixedly connected to the cross bar 42. The end of the cross bar 42 away from the shaft 43 is provided with a guide wheel 46 for clamping on the outside of the hopper 2. The top of the inner frame 2 of the sling is located on one side of the transmission rod 42 and is fixedly provided with a bracket 47. An electric push rod 48 is provided between the bracket 47 and the transmission rod 42. One end of the electric push rod 48 is rotatably connected to the bracket 47, and the other end is rotatably connected to the transmission rod 42.

[0045] In this embodiment, as the spreader inner frame 2 descends, the hopper 3 enters the spreader inner frame 2, guided by the guide assembly 5. As the spreader inner frame 2 descends, when the reverse hook 41 contacts the top of the hopper 4, an electrical limit switch is triggered for the electric push rod 48. The electric push rod 48 pushes the transmission rod 42, which in turn rotates the shaft 43 via the connector 44, rotating the guide wheel 46 90 degrees and locking it against the outside of the hopper 3. The electrical limit switch is triggered again, and the electric push rod 48 stops. The reverse hook 41 and the guide wheel 46 cooperate to secure the hopper 3 to the spreader inner frame 2, achieving automatic locking and securing of the hopper 3.

[0046] The electric push rod 46 moves in the opposite direction, driving the guide wheel 46 to rotate 90 degrees in the opposite direction, so that it is staggered with the hopper 3, thereby unlocking the hopper 3 and the sling inner frame 2. The sling inner frame 2 is lifted, and the hopper 3 and the sling inner frame 2 are automatically separated.

[0047] The automatic clamping and fixing component 4 has a reasonable structural design, smooth movement, and firm fixation, which effectively improves the transportation efficiency.

[0048] In a preferred embodiment, if Figure 5 As shown, upper crossbeams 31 are fixedly provided on both sides of the top of the hopper 3 corresponding to the reverse hooks 41, and lower crossbeams 32 are fixedly provided on both sides of the hopper 3 corresponding to the guide wheels 46. The clamping and fixing of the hopper 3 by the reverse hooks 41 and the guide wheels 46 improves the structural strength of the hopper 3 and meets the strength requirements for the hopper 3 to be turned over.

[0049] In a preferred embodiment, if Figure 1 and 4As shown, the guide assembly 5 includes a plurality of wheel frames 51 fixedly mounted on the bottom of the spreader inner frame 2. The wheel frames 51 are respectively distributed on both sides of each corner of the hopper 3. Guide wheels 52 are provided on the wheel frames 51. Under the guidance of the guide wheels 52, the hopper 3 can smoothly enter or exit the spreader inner frame 2.

[0050] In a preferred embodiment, if Figure 1 and Figure 5 As shown, a guide vertical beam 33 is fixedly provided at each corner of the hopper 3 corresponding to the guide wheel 52 to cooperate with the guide wheel 52 to achieve precise guidance; the distance between the guide wheel 52 and the guide vertical beam 33 is not greater than 2 cm, which avoids excessive shaking of the hopper 3 during transportation and ensures the stability of transportation.

[0051] In a preferred embodiment, if Figure 1 and Figure 2 As shown, outer mounting plates 11 are symmetrically fixed on both sides of the bottom of the sling outer frame 1, a bearing seat 12 is provided on the outer mounting plate 11, a rotating shaft 21 is rotatably connected to the bearing seat 12 through a bearing, and diagonal braces 13 are fixedly provided between both sides of the outer mounting plate 11 and the sling outer frame 1; an inner mounting plate 22 is fixedly provided on the bottom of the sling inner frame 2 corresponding to the outer mounting plate 11, and the rotating shaft 21 is fixedly connected to the inner mounting plate 22.

[0052] In this embodiment, the flip motor 6 is arranged on the outside of the outer mounting plate 11, and is used to drive the rotating shaft 21 to rotate, thereby driving the sling inner frame 2 to rotate through the inner mounting plate 22, so as to realize the flipping and dumping of materials by the hopper 3.

[0053] In a preferred embodiment, if Figure 3 and Figure 4 As shown, the sling outer frame 1 is a rectangular frame composed of four first beams; the sling inner frame 2 is a rectangular frame composed of four second beams; the first beams 1 and the second beams 2 are both made of stainless steel, with high structural strength, not easy to deform, not easy to corrode and rust, and long service life.

[0054] In a preferred embodiment, the flip motor 6 is a three-in-one motor consisting of a reducer, an electric motor and a brake, with a compact structure, large torque transmission, stable operation, low noise and long service life.
