Description

Technical Field

[0001] This utility model relates to the field of building material hopper technology, specifically a material flow regulating device for a building material discharge transition hopper. Background Technology

[0002] Construction material discharge transition hoppers are auxiliary equipment used for material conveying in construction. Their main function is to buffer, guide, and reduce material splashing when materials are transferred from high to low places.

[0003] When materials fall freely from a height, such as from a mixer, or fall at high speed into a hopper via a conveyor, they exert a strong impact force on the inner wall, bottom, and guide plates of the hopper. This impact force not only directly causes wear on the material surface, but also leads to material fatigue and accelerated deformation due to repeated impacts. Severe deformation or wear may cause the hopper structure to break, resulting in material collapse or equipment falling accidents, threatening the safety of on-site personnel. Therefore, it is necessary to provide a method that can prevent materials from directly contacting the inner wall of the hopper when they fall into it, thereby improving the service life of the hopper. Utility Model Content

[0004] The purpose of this utility model is to provide a material flow regulating device for a construction material discharge transition hopper, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a material flow regulating device for a construction material discharge transition hopper, comprising:

[0006] A fixed frame and a hopper, wherein the hopper is welded to the upper inner part of the fixed frame;

[0007] The protective assembly includes four fixed columns, a connecting plate, a first spring, and a baffle. The four fixed columns are welded to the center of the four sides of the upper surface of the hopper. The connecting plate passes through the outer surface of the fixed columns. The first spring is welded to the lower surface of the connecting plate. The baffle is in the shape of an inverted cone and is located in the center of the hopper. The outer surface of the baffle is welded and fixed to the lower end of the first spring.

[0008] Furthermore, a discharge port is fixed at the lower end of the hopper, and lifting rings are fixed at the four corners of the upper surface of the hopper.

[0009] Furthermore, a slot is provided at the upper end of the fixing column, and fixing blocks are welded to both sides of the fixing column.

[0010] Furthermore, a mounting hole is provided on one side of the fixing block, and the mounting hole corresponds to the card slot.

[0011] Furthermore, a second spring is fixed inside the mounting hole, and a retaining post is fixed to the end of the second spring, with the end of the retaining post extending into the slot.

[0012] Furthermore, it also includes a feeding assembly, which includes a connecting shaft, a feeding plate, and connecting rods. There are two connecting shafts, which are respectively welded to both sides of the feeding port. The feeding plate rotates through the outer surface of the connecting shaft and blocks the feeding port. There are two connecting rods, which are respectively welded to both sides of the feeding plate.

[0013] Furthermore, two electric push rods are fixed on one side of the fixed frame, and a movable plate is fixed to the output end of the electric push rod. Two fixed frames are fixed on the upper surface of the movable plate, and the fixed frames pass through the connecting rod.

[0014] This utility model has the following beneficial effects:

[0015] This utility model includes a fixed frame, hopper, discharge port, lifting ring, and protective components. When feeding material into the hopper, the locking pins are first pressed to both sides, causing the locking pins to compress the second spring into the mounting hole. Then, the connecting plates are passed through the fixed pins. Under the elastic force of the spring, the second spring quickly returns to its original shape, causing the locking pins to engage in the slots. After all four connecting plates are engaged in the fixed pins, the baffle is located in the center of the hopper. When concrete falls into the hopper, the concrete first contacts the baffle. The baffle absorbs part of the impact force through the elastic deformation of the first spring, reducing direct wear and deformation of the material in the hopper. Through the buffering and guiding effect of the baffle, the flow of material in the hopper is more stable. By pressing the locking pins to compress the second spring, the connecting plates can be quickly inserted into or pulled out of the fixed pin, realizing the quick installation or removal of the baffle.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a material flow regulating device for a construction material discharge transition hopper, comprising:

[0028] The fixed frame 11 and the hopper 12 are welded to the upper part of the inside of the fixed frame 11. The lower end of the hopper 12 is fixed with a discharge port 13, and the four corners of the upper surface of the hopper 12 are fixed with lifting rings 14.

[0029] The fixed frame 11 serves as the supporting frame for the entire structure, used to fix the hopper 12 and bear its weight and the impact load of the internal materials. The hopper 12 is used to hold materials such as concrete, sand and gravel, and guides the materials to flow from the top to the discharge port 13. The discharge port 13 is located at the bottom of the hopper 12 and is used to transport the materials to the next process.

[0030] The protective assembly includes four fixed posts 21, a connecting plate 22, a first spring 23, and a baffle 24. The fixed posts 21 are welded to the center of the four sides of the upper surface of the hopper 12. The connecting plate 22 passes through the outer surface of the fixed posts 21. The first spring 23 is welded to the lower surface of the connecting plate 22. The baffle 24 is in the shape of an inverted cone and is located in the center of the inside of the hopper 12. The outer surface of the baffle 24 is welded and fixed to the lower end of the first spring 23.

[0031] The fixed column 21 serves as a support structure for the connecting plate 22 and the baffle 24, ensuring the stability of the baffle 24 in the center position of the hopper 12. The connecting plate 22 is used to fix the baffle 24 and transmit the spring force. The first spring 23 provides elastic buffering capacity for the baffle 24. The first spring 23 is selected from compression springs and tension springs, and its stiffness and preload are adjusted according to the working conditions.

[0032] The upper end of the fixing post 21 is provided with a slot 211, and fixing blocks 25 are welded on both sides of the fixing post 21. A mounting hole 26 is provided on one side of the fixing block 25, and the mounting hole 26 is directly corresponding to the slot 211. A second spring 27 is fixed inside the mounting hole 26, and a locking post 28 is fixed at the end of the second spring 27, and the end of the locking post 28 extends into the slot 211.

[0033] The baffle 24 is used to withstand the first wave of impact from the material and protect the inner wall of the hopper 12. The baffle 24 disperses the material evenly in all directions through the elastic action of the first spring 23, reducing local wear. The baffle 24 is in the shape of an inverted cone, which facilitates the flow of material in all directions. The slot 211 is used to cooperate with the locking post 28 to fix the connecting plate 22. The fixing block 25 is used to install the second spring 27 and the locking post 28. The mounting hole 26 is used to accommodate the second spring 27 and the locking post 28. After the locking post 28 is pressed, the second spring 27 quickly returns to its original shape and pushes the locking post into the slot 211 to achieve automatic locking. Under the elastic force of the second spring 27, the locking post 28 is locked into the slot 211 to fix the connecting plate 22.

[0034] Working principle:

[0035] When feeding material into the hopper 12, first press the locking post 28 to both sides. The locking post 28 drives the second spring 27 to compress into the mounting hole 26. Then, pass the connecting plate 22 through the fixing post 21. Under the action of the spring force, the second spring 27 will quickly recover its deformation and drive the locking post 28 into the slot 211. After all four connecting plates 22 are inserted into the fixing post 21, the baffle 24 is located in the center of the hopper 12. When concrete falls into the hopper 12, the concrete will first contact the baffle 24. The baffle 24 absorbs part of the impact force through the elastic deformation of the first spring 23, reducing the direct wear and deformation of the material on the hopper.

[0036] In this step, the material flows more smoothly in the hopper 12 through the buffering and guiding effect of the baffle 24. By pressing the locking post 28 to compress the second spring 27, the connecting plate 22 can be quickly inserted into or pulled out of the fixing post 21, so as to realize the quick installation or removal of the baffle 24.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The feeding assembly includes a connecting shaft 31, a feeding plate 32, and a connecting rod 33. There are two connecting shafts 31, which are welded to both sides of the feeding port 13. The feeding plate 32 rotates through the outer surface of the connecting shaft 31 and blocks the feeding port 13. There are two connecting rods 33, which are welded to both sides of the feeding plate 32. Two electric push rods 34 are fixed on one side of the fixing frame 11. A movable plate 35 is fixed to the output end of the electric push rod 34. Two fixing frames 36 are fixed on the upper surface of the movable plate 35, and the fixing frames 36 pass through the connecting rod 33.

[0039] The connecting shaft 31 serves as the rotation shaft of the feeding plate 32, supporting the feeding plate 32 and allowing it to rotate around the shaft. The feeding plate 32 controls the opening and closing of the feeding port 13 by rotation, adjusting the speed and amount of material flow. The connecting rod 33 transmits the rotational motion of the feeding plate 32 to the drive system of the fixed frame 36 and the electric push rod 34. The electric push rod 34 serves as a power source, driving the movable plate 35 and the fixed frame 36 through linear motion, thereby driving the connecting rod 33 and the feeding plate 32 to rotate.

[0040] The movable plate 35 serves as the connecting component between the output end of the electric push rod 34 and the fixed frame 36, transmitting the linear motion of the electric push rod 34 to the fixed frame 36. The fixed frame 36 serves as the guide and support structure for the connecting rod 33, ensuring that the up-and-down movement direction of the connecting rod 33 is consistent with the thrust direction of the electric push rod 34.

[0041] Working principle:

[0042] Once the hopper 12 is filled with concrete, it is lifted by the lifting ring 14 to the position where it needs to be poured. Then, the electric push rod 34 is activated by the external controller. The electric push rod 34 drives the movable plate 35 to move upward. The movable plate 35 moves upward, which in turn drives the fixed frame 36 to move upward. The fixed frame 36 drives the connecting rod 33 to move upward. The connecting rod 33 moves upward, which in turn drives the discharge plate 32 to rotate. The rotation of the discharge plate 32 opens the discharge port 13. The rotation angle of the discharge plate 32 can be precisely controlled by adjusting the stroke of the electric push rod 34, thereby adjusting the opening and closing degree of the discharge port 13.

[0043] This step eliminates the need for direct manual contact with the hopper 12, thus avoiding operational risks associated with working at heights or in harsh environments.
