Description

Technical Field

[0001] This utility model relates to the field of grain conveying and transfer equipment, and in particular to a powder transfer device capable of automatic unloading. Background Technology

[0002] In the brewing process, especially within the brewing workshop and between the brewing workshop and the grain depot, the transfer of powdery materials such as grain, koji powder, and rice husks is relatively frequent. The convenience and suitability of the transfer tools can greatly improve production efficiency, reduce labor intensity, and enhance operational efficiency.

[0003] Therefore, there is an urgent need for a transfer tool that can effectively handle the transfer and storage of powders in various brewing workshops and within the workshops, in conjunction with other transportation tools (forklifts, overhead cranes, box trucks, etc.); and can automatically unload stored powders without the aid of other power sources. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a powder transfer device that can automatically unload materials, using hoisting equipment to transfer materials and achieve automatic unloading.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a powder conveying device capable of automatic unloading, including a bucket body, an arc-shaped discharge port at the lower end of the bucket body, two sets of arc-shaped gates at the arc-shaped discharge port, the arc-shaped gates being driven by a drive mechanism located on one side of the bucket body, each drive mechanism including two sets of rotating handles, the upper end of the rotating handles being hinged to a fixed pin shaft, the lower end being connected to the arc-shaped gates, the fixed pin shaft being fixed to the outside of the bucket body, the middle part of the rotating handles being hinged to one end of a connecting rod, the other end of the connecting rod being hinged to a support pin shaft, a sliding groove being provided on the outside of the bucket body, the end of the support pin shaft being slidably installed in the sliding groove, and a top fork being provided on the top of the receiving workpiece for receiving material in the bucket body, the top fork being used to lift the support pin shaft upward when the bucket body moves downward.

[0006] In a preferred embodiment, the handle includes a straight section and a fan-shaped section. The outer arc of the fan-shaped section is connected to the arc-shaped door and has the same curvature as the arc-shaped door. The end of the connecting rod is hinged to the intersection of the straight section and the fan-shaped section.

[0007] In a preferred embodiment, a support frame is provided on the outer side of the bucket body, and a lifting lug is provided on the top of the support frame.

[0008] In a preferred embodiment, the bottom of the support frame is provided with several support blocks.

[0009] In a preferred embodiment, the upper end of the top fork is provided with a "V" shaped groove.

[0010] This utility model provides an automatic powder transfer device that assists hoisting equipment in transferring materials. When the bucket moves downward, the top fork limits the support pin, causing the support pin to move upward relative to the bucket. A connecting rod drives the rotating handle to rotate along the fixed pin, causing the arc-shaped door to rotate and the arc-shaped discharge port to open, achieving automatic unloading. After unloading is complete, the bucket moves upward. When the support pin leaves the top fork, it moves downward under gravity, resetting the arc-shaped door and closing it. This device achieves automatic unloading without the need for additional power, effectively handling powder transfer and storage operations. Attached Figure Description

[0015] like Figures 1-2 As shown, an automatic powder conveying device includes a hopper 1 with an arc-shaped discharge port at its lower end. In practical use, a support frame 9 is provided on the outer side of the hopper 1, and a lifting lug 10 is provided on the top of the support frame 9. The lifting lug 10 can also be directly installed on the upper end of the hopper 1. The support frame 9 improves the stability of the entire hopper 1 and facilitates lifting and placement. Several support blocks 11 are provided at the bottom of the support frame 9 to ensure stable placement of the hopper 1 on the ground.

[0016] The arc-shaped discharge port is equipped with two sets of arc-shaped gates 2. In actual implementation, baffles can be installed on both sides of the arc-shaped gates 2 to block the two sides of the arc-shaped gates 2 and prevent material leakage.

[0017] The arc-shaped gate 2 is driven by a drive mechanism located on one side of the bucket body 1. Two drive mechanisms can be provided, one on each side of the bucket body 1. The drive mechanism includes two sets of rotating handles 3. The upper end of the rotating handle 3 is hinged to the fixed pin 4, and the lower end of the rotating handle 3 is connected to the arc-shaped gate 2 for driving the arc-shaped gate 2. The fixed pin 4 is fixed on the outside of the bucket body 1, specifically located at the center position corresponding to the arc-shaped discharge port.

[0018] The middle part of the handle 3 is hinged to one end of the connecting rod 5, and the other end of the connecting rod 5 is hinged to the support pin 6. The outer side of the bucket body 1 is provided with a sliding groove 12, which is vertically arranged and located directly below the fixed pin 4. The end of the support pin 6 is slidably installed in the sliding groove 12. The top of the receiving workpiece 7, which is used to receive the material in the bucket body 1, is provided with a top fork 8. When the bucket body 1 moves above the receiving workpiece 7, the top fork 8 is located below the support pin 6. When the bucket body 1 moves downward, the top fork 8 pushes the support pin 6 upward, providing power for the rotation of the handle 3.

[0019] In this embodiment, the top fork 8 is provided with a "V" shaped groove 801 at the upper end, which is used to limit the support pin 6 and prevent the support pin 6 from disengaging from the top fork 8.

[0020] The top fork 8 is equipped with a buffer layer, which can effectively reduce the impact with the top support pin 6.

[0021] Preferably, the handle 3 includes a straight portion 301 and a fan-shaped portion 302. The outer arc of the fan-shaped portion 302 connects to the arc-shaped door 2 and matches the curvature of the arc-shaped door 2. The end of the connecting rod 5 is hinged to the intersection of the straight portion 301 and the fan-shaped portion 302. By providing the fan-shaped portion 302, it is convenient to connect to the arc-shaped door 2, and it can effectively prevent material leakage by sealing both sides of the arc-shaped door 2.

[0022] The working principle of this device is as follows:

[0023] By using hoisting equipment, such as an overhead crane, the bucket 1 is hoisted above the receiving workpiece 7 that needs to receive the material from the bucket 1. The bucket 1 is then moved downwards. When the bearing pin 6 contacts the top fork 8, the bucket 1 continues to move downwards. The top fork 8 limits the bearing pin 6, causing the bearing pin 6 to move upwards relative to the bucket 1. The connecting rod 5 drives the rotating handle 3 to rotate along the fixed pin 4, causing the arc-shaped door 2 to rotate and the arc-shaped discharge port to open, thus achieving automatic unloading. After unloading is completed, the bucket 1 moves upwards. When the bearing pin 6 leaves the top fork 8, under the action of gravity, the bearing pin 6 moves downwards, and the arc-shaped door 2 resets and closes.

[0024] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
