Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a conveyor belt hopper with a material distribution function. Background Technology

[0002] In tobacco leaf threshing and re-drying production lines, belt conveyors are the core equipment for material transport. However, because the upper and lower belts often overlap vertically, the material (tobacco leaves) tends to concentrate in the middle of the belt, forming a pile-up. This material accumulation not only prevents the material from being fully loosened but also easily leads to blockages when entering downstream equipment such as vibrating screens, thinners, and air separators. Failure to detect and address blockages in a timely manner will severely impact production efficiency and may even cause downtime. Furthermore, material accumulation reduces the performance of downstream equipment, affecting the stability and consistency of product quality. Therefore, this application aims to provide a belt conveyor discharge hopper with a material equalization function to solve this problem. Utility Model Content

[0021] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art.

[0022] Example 1

[0023] like Figure 1-4 As shown, this embodiment is a conveyor belt hopper with a material distribution function, including a housing 1, a guide plate 2, and an adjustment mechanism 3. The housing 1 has openings at both the upper and lower ends. The guide plate 2 is disposed inside the housing 1. There are two guide plates 2, which are spaced apart from each other. The upper ends of the two guide plates 2 are rotatably connected to the two sides of the opening at the upper end of the housing 1 by hinges 5. In this way, the inclination directions of the two guide plates 2 are exactly opposite, which facilitates the guidance of materials to the two sides of the housing 1.

[0024] In this embodiment, the adjustment mechanism 3 is used to adjust the angle of the guide plate 2 relative to the inner wall of the housing 1. The adjustment mechanism 3 includes an adjustment screw 31 and a movable base. The adjustment screw 31 is mounted on the housing 1. One end of the adjustment screw 31 is provided with a handle 32. The other end of the adjustment screw 31 passes through the side wall of the housing 1 and is connected to the movable base. One side of the movable base contacts the lower surface of the guide plate 2, providing support for the guide plate 2.

[0025] In this embodiment, a threaded structure is provided on the side wall of the housing 1. The adjusting screw 31 cooperates with the threaded structure. By rotating the handle 32, the length of the adjusting screw 31 entering the housing 1 is changed, thereby adjusting the angle of the guide plate 2. The threaded structure in this embodiment can be any existing structure or device that can support the rotation of the adjusting screw 31 to adjust its length entering the housing 1. For example, the simplest threaded structure is a nut horizontally fixed on the side wall of the housing 1. When the adjusting screw 31 extends into the housing 1, it will drive the movable base to move, thereby causing the movable base to generate a thrust on the lower surface of the guide plate 2. The movable base and the guide plate 2 can slide relative to each other, causing the guide plate 2 to flip upward. Conversely, when the adjusting screw 31 is pulled out of the housing 1, the guide plate 2 will flip downward. That is, the adjusting screw 31 can flexibly change the tilt angle of the guide plate 2.

[0026] In this embodiment, the movable base includes a base plate 6, a pin 8, an ear seat 7, and a bearing seat 9; the ear seat 7 is fixedly disposed on the base plate 6, the two ends of the pin 8 are disposed in the ear seat 7, the bearing seat 9 is movably mounted on the pin 8, and the bearing seat 9 is provided with a bearing, which is connected to the end of the adjusting screw 31.

[0027] In this embodiment, the housing 1 is flared with a smaller top and a larger bottom. An inspection window 4 is provided on the side wall of the housing 1, and a baffle is provided at the inspection window 4. The baffle is made of transparent glass.

[0028] The working principle of this embodiment is as follows: When the material from the front belt enters the downstream equipment, due to the vertical overlap between the belt conveyor and the downstream equipment, the material tends to concentrate in the middle of the belt, resulting in severe swarming. By placing the hopper at the discharge port of the front belt in this embodiment, the material first passes through the hopper and then flows out. The outflowing material is then divided into three streams that fall onto the equipment below. Specifically, by adjusting the angle of one of the guide plates 2, one-third of the material can be guided to one side of the belt; adjusting the other guide plate 2 can guide another third of the material to the other side of the belt; and the remaining third of the material can directly fall through the gap between the two guide plates 2 into the middle of the downstream equipment belt. This effectively achieves uniform material distribution on the (downstream equipment) belt.

[0029] In some other embodiments, a groove can be provided at the upper end of the housing 1. The groove is horizontal and a slider is provided in the groove. The hinge 5 of the guide plate 2 is fixed on the slider. When needed, the slider can be moved so that the guide plates 2 move synchronously. This allows the spacing between adjacent guide plates 2 to be adjusted to regulate the distribution of materials. Generally, when the two guide plates 2 are close together, the amount of material falling between the guide plates 2 will decrease, and the amount of material distributed to both sides will increase. Conversely, when the guide plates 2 are far apart, more material will fall between the guide plates 2, that is, the material will be concentrated in the middle of the (lower belt) and the amount of material distributed to both sides will decrease.

[0030] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
