For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The following is combined with Figures 1 to 5 The utility model is further described.

[0032] Embodiment 1

[0033] In order to solve the technical problems existing in the background technology, this embodiment provides a hopper that closes its door by its own weight.

[0034] The specific technical solution includes a frame 1 and a hollow square bucket 2 arranged on the frame 1. The frame 1 plays a supporting role in the entire device and is used to be connected to the crane's lifting device. The bucket 2 plays a containing role and is used for temporary storage of wine lees.

[0035] The further design is as follows: to facilitate the entry of materials into the bucket body 2, the top of the bucket body 2 is open and the top of the bucket body 2 is used as the feed port; to facilitate unloading, a discharge port 202 and a material door 203 matching the number of the discharge ports 202 are provided at the bottom of the bucket body 2. The material door 203 includes an arc-shaped bottom plate and side plates connected to both ends of the bottom plate, and the discharge port 202 is opened and closed by rotating the material door 203.

[0036] Among them, in order to improve the discharge efficiency, a V-shaped partition 201 is arranged at the lower part of the bucket body 2 along the length direction of the bucket body 2, and the partition 201 divides the discharge port 202 at the bottom of the bucket body 2 into two; door opening components 3 for driving the material door 203 to automatically open the discharge port 202 are arranged on both sides of the width direction of the bucket body where the frame 1 is located, and the bucket body 2 automatically closes the discharge port 202 by the dead weight of the material door 203; the door opening component 3 can drive the two material doors to rotate synchronously to open and close the discharge port 202.

[0037] The above structure is the same as the self-opening hopper structure mentioned in the background technology. At the same time, in order to solve the technical problems that the self-opening mechanism in the background technology adopts a double guide rod structure, resulting in uneven force on the guide rods, unsmooth door opening and closing, easy jamming and complex structure, this embodiment makes further improvements to the door opening assembly.

[0038] The further design of the door opening assembly is as follows: the door opening assembly 3 includes a guide rod 301 vertically arranged between the two material doors 203, a first guide seat 302 is arranged on the frame 1, a first bearing 303 is arranged in the first guide seat 302, the first bearing 303 is a linear bearing, the guide rod 301 is movably connected to the frame 1 through the first bearing 303, a first connecting plate 304 is fixedly connected to the guide rod 301, a fan-shaped ear plate 305 is fixedly connected to the material door 203, the first connecting plate 304 is hinged to the ear plate 305 through the second connecting plate 306, and the middle part of the ear plate 305 is hinged to the frame 1.

[0039] Working principle: The hopper of this embodiment is used in conjunction with a crane (not shown in the figure) to complete the transfer of materials. A sling (not shown in the figure) is installed at the end of the crane. The crane is connected to the hopper through the sling. A power assembly is arranged just above the guide rod 301 where the sling is located. The power assembly can be any one of an electric cylinder, a pneumatic cylinder, and an electric push rod. The electric push rod is preferably used in this embodiment because of its simple arrangement. After the crane hoists the hopper to the designated location, when it needs to be unloaded, refer to Figure 2 , the electric push rod extends out and presses the guide rod 301 downward. During the downward movement of the guide rod 301, the guide rod 301 drives the ear plate 305 to rotate around the hinge point 309 through the first connecting plate 304. Since the ear plate 305 is fixedly connected to the material door 203, the material door 203 rotates synchronously with the ear plate 305. During the rotation of the material door 203, the material door 203 gradually opens the discharge port 202 until the discharge port 202 is fully opened, and finally the unloading is completed. It is worth noting that the two material doors 203 of the present application open the discharge port 202 by synchronous rotation. When the discharge port 202 needs to be closed after the unloading is completed, the electric push rod on the sling retracts. Since the hinge point 309 is set just above the material door 203, the material door 203 will automatically rotate to just below the discharge port 202 under the action of its own gravity, and the discharge port 202 is completely closed. At this time, the guide rod 301 will also move up and reset synchronously.

[0040] The opening degree of the material door 203 is controlled by the stroke of the electric push rod to avoid excessive opening of the material door 203.

[0041] From the structure and working principle of the above-mentioned door opening assembly, it can be seen that compared with the self-opening hopper in the prior art, the door opening assembly of the present application adopts a single guide rod structure, the guide rod is more evenly stressed, the door is opened and closed more smoothly, is not prone to jamming, and has a simpler structure.

[0042] To improve the resetting capability of the material door 203, refer to Figure 2 In this embodiment, the top of the ear plate 305 near the second connecting plate 306 is connected to the frame 1 through a spring 4. In the process of closing the discharge port 202, the spring 4 will pull the material door 203 to reset under the effect of its own elastic performance.

[0043] Among them, the present application also optimizes the angle of the partition 201. The angle of the partition 201 cannot be too large, otherwise the slope of the partition 201 will be small, and materials will easily accumulate on the inclined surface of the partition 201; the angle of the partition 201 cannot be too small, otherwise the discharge port 202 will be too large, and the corresponding material door 203 area will increase, which will increase the load of the power component and make it more difficult to open and close the door. For this reason, the present application optimizes the angle α of the partition 201 to 40° to avoid material accumulation in the hopper and reduce the difficulty of opening the hopper door.

[0044] In order to improve the strength and rigidity of the partition plate 201 , a first reinforcing rib 204 is provided on the partition plate 201 .

[0045] Embodiment 2

[0046] In order to solve the technical problems in the background technology that the self-opening door mechanism adopts a single guide seat, which leads to uneven force on the guide rod, unsmooth door opening and closing, easy jamming and complex structure, on the basis of embodiment one, this embodiment further provides a second guide seat 307 on the frame 1 below the first guide seat 302, and a second bearing 308 is provided in the second guide seat 307. The guide rod 301 is movably connected to the frame 1 through the second bearing 308, and the guide rod 301 vertically penetrates the first guide seat 302 and the second guide seat 307, and the second bearing 308 is a linear bearing.

[0047] It can be seen that the self-opening hopper in the background technology adopts a single guide seat, while this embodiment adopts a double guide seat. The double bearing support guide mechanism is designed, and the two-point straight line principle is used. The guide mechanism adopts a double support structure to make it evenly stressed, open and close smoothly, and slide flexibly.

[0048] Embodiment 3

[0049] In order to solve the technical problem that the self-opening hopper in the background technology has no limit mechanism, resulting in excessive closing of the door, based on the first embodiment, referring to Figure 2 and Figure 3 In this embodiment, a limit plate 5 is further provided at the lower part of the guide rod 301. The setting of the limit plate 5 prevents the guide rod 301 from moving upward without limit, and the limit plate 5 will abut against the bottom of the second guide seat, so that the material door can effectively control the closing degree within a certain range under its own weight.

[0050] In order to improve the strength and rigidity of the material door 203 , a second reinforcing rib (not shown in the figure) is provided at the bottom of the material door 203 .

[0051] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
