Description
Technical Field
[0001] The utility model relates to the technical field of material conveying, in particular to a feeding hopper device. Background Art
[0002] The feed hopper is used to feed materials, and is mainly a hopper-shaped structure, with its bottom surface and / or one side open to discharge materials. In order to facilitate the entry and downward sliding of materials, the inner side of the feed hopper is an inclined surface inclined outward.
[0003] In the existing feed hopper, if the height is limited, in order to increase the volume of the hopper, the sides are often tilted further outward, such as tilted to 30°, so that the volume of the hopper can be increased accordingly. However, in this case, on the one hand, the overall length and width of the feed hopper will increase, which is not conducive to limiting the overall length and width control of the hopper. On the other hand, the small tilt angle is not conducive to the material sliding down. If the overall length and width are reduced by increasing the tilt angle, the height of the feed hopper will increase. For a feed hopper that needs to be moved, whether it is an increase in width or height, it may exceed the requirements of width and height limits and affect the movement of the feed hopper or the carrier that loads the feed hopper.

In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0035] Please refer to Figures 1 to 4 A preferred embodiment of the utility model provides a feeding hopper device, which mainly includes a side folding portion 10, an end folding portion 20, a rotating mechanism 30 and a first driving cylinder 40.
[0036] There are two side folding parts 10, which are respectively located on two opposite sides. The inner side of the side folding part 10 is a smooth plane, and the outer side is provided with reinforcing ribs to improve the side folding part 10. The side folding part 10 is trapezoidal in shape as a whole.
[0037] There is one end face folded portion 20, which is located between the ends of the two side face folded portions 10. The inner side of the end face folded portion 20 is a smooth plane, and the outer side is provided with reinforcing ribs to improve the end face folded portion 20. The end face folded portion 20 is trapezoidal in shape as a whole.
[0038] The rotating mechanism 30 includes a fixed seat 31 and a rotating part 32 rotatably mounted on the fixed seat 31. There are multiple rotating mechanisms 30, and the multiple rotating mechanisms 30 are rotatably connected with the side folding part 10 or the end folding part 20 through the rotating parts 32 so that the side folding part 10 or the end folding part 20 can rotate around the rotating mechanism 30. In this preferred embodiment, each side folding part 10 or the end folding part 20 is equipped with two rotating mechanisms 30. The fixed seat 31 of the rotating mechanism 30 is fixedly mounted on a supporting structure such as a table top or a frame. For example, in a specific exemplary embodiment, the fixed seat 31 of the rotating mechanism 30 is fixedly mounted on a crawler mobile crushing station.
[0039] There are multiple first drive cylinders 40, which are respectively connected to the side folding part 10 or the end folding part 20. One end of the first drive cylinder 40 is rotatably connected to the middle position of the outer side surface of the side folding part 10 or the end folding part 20 through a hinge support 50, and the other end is provided with a hinge support 50, and is connected to the external structure through the hinge support 50, such as installing the hinge support 50 on a supporting structure such as a table top and a frame. In a specific exemplary embodiment, the hinge support 50 on the first drive cylinder 40 away from the side folding part 10 or the end folding part 20 is installed on a crawler mobile crushing station, and the hinge support 50 is arranged on the through pipe so that the side folding part 10 and the end folding part 20 can be rotated outward and folded when the first drive cylinder 40 drives them, and can also be rotated inward to form a feed hopper structure.
[0040] During implementation, as in the exemplary embodiment of the present invention, the feed hopper device is installed on the crawler mobile crushing station through the rotating mechanism 30, the hinge support 50, etc. thereon. When the feed hopper structure is required, the first drive cylinder 40 extends so that the side folding portion 10 and the end face folding portion 20 can move toward each other until the two side edges of the end face folding portion 20 are respectively abutted against the side edges of the two side folding portions 10 close to the end face folding portion 20, so that the side folding portion 10 and the end face folding portion 20 form a feed hopper structure (such as Figure 1 and Figure 2 As shown in the figure, at this time, the bottom of the feed hopper structure and the other end face away from the end face folding portion 20 are hollowed out. After the material enters the feed hopper, it slides down to the bottom hollow along the inner side of the side folding portion 10 and the end face folding portion 20, and the crawler mobile crushing station is provided with a feeder, which is close to one side of the hollow end face and located under the hollow bottom, so that the material entering the feed hopper can be transported away; and when the folding feed hopper device needs to be stored, the first driving cylinder 40 contracts so that the side folding portion 10 and the end face folding portion 20 can move away from each other and fit in the direction of the rotating mechanism 30 (such as fitting to the outer side of the rotating mechanism 30) to achieve storage and folding (such as Figure 3 and Figure 4As shown in the figure, the height and width of the folded feed hopper device are smaller than the height and width of the feed hopper structure, so as to meet the requirements of height limit and line width by transforming into a morphological structure with smaller height and width. For example, in an exemplary embodiment, the volume under the feed hopper structure can reach 5 cubic meters, and when the feed hopper is expanded, the width of the folded feed hopper is kept within 3 meters, which can meet the requirement of 3m width limit of the whole machine.
[0041] It is understandable that in other preferred embodiments, there may be two end face folding portions 20, which are arranged opposite to each other. In this case, the feed hopper formed is a structure with an open bottom and closed sides.
[0042] In a preferred embodiment, when the side folding portion 10 and the end face folding portion 20 form a feed hopper structure, the side folding portion 10 and the end face folding portion 20 are inclined outward and the inclination angle of the side folding portion 10 and the end face folding portion 20 facing the inner side is 50-70°. By setting the inward side of the side folding portion 10 and the end face folding portion 20 with a more inclined angle, the material can be better slid down, such as sliding down onto the feeder. In an exemplary embodiment, the inclination angle of the inward side of the side folding portion 10 and the end face folding portion 20 is 60°. Although the side folding portion 10 and the end face folding portion 20 with a larger inclination angle will cause the overall height to become higher when the feed hopper structure is formed, since the feed hopper device of the utility model can be stored and folded, when the height needs to be reduced, it can be converted into a stored and folded state to meet the height limit requirements. By setting, the side folding portion 10 and the end face folding portion 20 with a larger inclination angle can drop the material faster and prevent sticking and jamming.
[0043] Preferably, the first drive cylinder 40 is one of an oil cylinder, a gas cylinder or an electric cylinder. In this exemplary embodiment, the first drive cylinder 40 is an oil cylinder. The end of the body of the first drive cylinder 40 is rotatably connected to the hinge support 50, and the end of the telescopic rod of the first drive cylinder 40 is rotatably connected to the outer middle part of the side folding part 10 or the end face folding part 20.
[0044] In a preferred embodiment, an extension portion 60 is detachably provided on the top of the side folding portion 10 and the end folding portion 20, and the extension portion 60 extends along the top of the side folding portion 10 or the end folding portion 20. Thus, by providing the extension portion 60, the height of the side folding portion 10 and the end folding portion 20 is made higher, so as to increase the volume of the feed hopper and meet the use demand of a larger volume. For example, in an exemplary embodiment, the volume of the feed hopper with the extension portion 60 added is expanded from 5 cubic meters to 7.5 cubic meters, which meets the customer's ultra-large volume selection and makes the hopper more diversified. The extension portion 60 can be removed in a detachable manner when the expansion is not renewed, and the detachable manner preferably uses a bolt connection manner.
[0045] In an exemplary embodiment, the side folding portion 10 and the end folding portion 20 are made of Q690 material, which has higher strength and wear resistance than the ordinary Q355B material.
[0046] The side folding portion 10 is provided with a hooking portion 11, which is installed on the side of the outer side of the side folding portion 10 near the side of the end face folding portion 20, so that when the side folding portion 10 and the end face folding portion 20 form a feed hopper structure, the hooking portion 11 hooks the end face folding portion 20 on the outer side of the end face folding portion 20, so that when the feed hopper structure is formed, the end face folding portion 20 can be hooked to achieve a limit on the end face folding portion 20. The hooking portion 11 is L-shaped as a whole, with one end fixedly connected to the side folding portion 10 and the other end bent, so as to hook the end face folding portion 20 through the bending of the end. When the extension portion 60 is provided, the hooking portion 11 can also be provided on the extension portion 60 of the side folding portion 10, so as to hook the outer side of the extension portion 60 of the end face folding portion 20 when the feed hopper structure is formed.
[0047] Furthermore, a limiting portion 33 is provided on the fixing seat 31 connected to the side folding portion 10, and when the side folding portion 10 and the end face folding portion 20 form a feed hopper structure, a gap 34 is formed between the limiting portion 33 and the rotating portion 32 on the outer side of the side folding portion 10. A second driving cylinder 70 is provided on the outer side of the side folding portion 10, one end of the second driving cylinder 70 is rotatably connected to the side folding portion 10, and the other end is provided with a stopper 71, and the stopper 71 can enter the gap 34 under the drive of the second driving cylinder 70 and abut against the rotating portion 32 and the limiting portion 33 respectively. During implementation, when the side folding portion 10 and the end face folding portion 20 form a hopper structure, the second driving cylinder 70 drives the stopper 71 to enter the gap 34 and abut against the rotating portion 32 and the limiter 33, so that the side folding portion 10 cannot be rotated outward by the limiter of the stopper 71. At this time, the first driving cylinder 40 is not required to keep the side folding portion 10 pressed tightly. When folding and storage is required, the second driving cylinder 70 drives the stopper 71 upward to contact the limiter, which will not affect the storage and folding.
[0048] Further, a slide groove is provided on the rotating part 32, and the limiting part 33 is slidably provided on the slide groove. The second drive cylinder 70 is rotatably connected with the limiting part 33 through a hinge support, and the second drive cylinder 70 is rotatably connected with the locking part 71 through a pin shaft. The second drive cylinder 70 is one of an oil cylinder, an air cylinder or an electric cylinder. In this exemplary embodiment, the second drive cylinder 70 is an oil cylinder. The limiting part 33 has an action surface 35 on both sides, and the action surface 35 is used to abut against the rotating part 32 and the limiting part 33. The action surface is a plane to increase the contact area.
[0049] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
