Description

Technical Field

[0001] The utility model relates to the technical field of chute pipes for grain conveying, in particular to a chute pipe device for decelerating and reducing breakage. Background Art

[0002] A chute pipe is a device that uses the gravitational force of materials to convey materials from a high place to a low place, and is widely used in grain and oil processing plants, mechanized granaries and other processing and transportation industries. They do not require power drive, have a simple structure, are easy to manufacture, are economical to use, and have high efficiency and convenience.

[0003] However, due to the long length of the chute pipe and its inclined arrangement, the materials are affected by gravity in the chute pipe, the running speed increases, which will cause serious wear of the chute pipe wall; the collision force and impact force are large, resulting in serious breakage of the materials, and the materials are distributed chaotically in the chute pipe, and then the feeding of the equipment at the rear end of the chute pipe is uneven.

[0004] To solve the above practical problems, generally, designs such as thickening the chute pipe, lining the inside with wear-resistant materials, adding buffer strips, and reducing the feeding angle are adopted. Although these solutions reduce the material flow rate and impact force to a certain extent, and also reduce the wear degree of the chute pipe and improve the durability of the chute pipe, they will increase the weight of the chute pipe and require additional support, and have little effect on the chaotic flow of materials. Summary of the Invention

[0005] The utility model provides a chute pipe device for decelerating and reducing breakage to solve the problems of fast flow rate, high breakage rate and uneven material flow in a conventional chute pipe. A plurality of buffer hoppers are connected in series in the long chute pipe, and the buffer hoppers are used to decelerate and reduce the breakage of the materials, and can realize the uniform flow of materials, thereby ensuring the uniform feeding of the rear-end equipment.

[0006] To achieve the above object, the technical solution adopted by the utility model is:

[0007] A chute pipe device for decelerating and reducing breakage includes a chute pipe body and buffer hoppers. A plurality of the buffer hoppers are connected in series on the chute pipe body, there is a gap between adjacent two buffer hoppers, and the buffer hoppers and the chute pipe body are communicated to facilitate the flow of materials between the chute pipe body and the buffer hoppers;

[0008] The buffer hopper is a hollow pipe body structure with openings at both the upper and lower ends to facilitate the entry and exit of materials. Baffle plates are symmetrically arranged on the left and right sides inside the buffer hopper. The baffle plates are inclined between the inlet and outlet of the buffer hopper to facilitate blocking the materials to obtain buffering. Along the inlet to the outlet of the buffer hopper, the distance between the baffle plates on both sides gradually decreases, restricting the flow rate and velocity of the materials;

[0009] The left and right side walls of the buffer hopper expand outward in a trapezoidal shape to increase the distance between the baffle plate and the side walls of the buffer hopper. A diversion chamber is formed between the baffle plate and the left and right side walls of the buffer hopper, facilitating the uniform diversion of materials within the buffer hopper.

[0010] Further, the main body of the chute pipe is a pipe structure formed by flange connecting several sections of chute pipe arranged in a straight line. The length of the main body of the chute pipe can be selected according to the actual scenario. The main body of the chute pipe is flange connected to the buffer hopper, facilitating the disassembly and assembly of the buffer hopper. Multiple buffer hoppers are arranged at equal intervals.

[0011] Further, the upper opening of the buffer hopper is the buffer inlet, and the lower opening is the buffer outlet. The buffer inlet and the buffer outlet are vertically corresponding and connected. The baffle plate is arranged between the buffer inlet and the buffer outlet.

[0012] Further, support plates are symmetrically arranged on the left and right sides inside the buffer hopper to facilitate the support of the baffle plate. The two support plates are arranged in an inverted "V" shape. Each support plate is screw-connected with the baffle plate, facilitating the disassembly and assembly between the baffle plate and the support plate. The baffle plate is a plate body made of non-metallic material, reducing the impact force on the materials.

[0013] Further, a support angle steel is also arranged below each support plate. The two ends of the support angle steel are connected and fixed to the side walls of the buffer hopper, improving the installation strength of the support plate and increasing the reliability of the support for the baffle plate.

[0014] Further, a maintenance opening is formed on the side wall of the buffer hopper. A maintenance door is detachably arranged on the buffer hopper. The maintenance door closes the maintenance opening. A chain is also arranged between the maintenance door and the buffer hopper to prevent the maintenance door from falling off the buffer hopper.

[0015] Further, the maintenance door is a double-layer plate structure. The maintenance door includes an inner layer plate and an outer layer plate that are attached together. The cross-section of the inner layer plate is adapted to the cross-section of the maintenance opening. The inner layer plate is embedded into the maintenance opening, facilitating the blocking of the maintenance opening. The cross-section of the inner layer plate is smaller than that of the outer layer plate. A handle is arranged on the outer layer plate, facilitating the manual movement of the maintenance door.

[0016] Further, a door lock assembly for controlling the opening and closing of the maintenance door is also arranged on both sides of the buffer hopper. The door lock assembly includes a pressing block and a hand-tightening bolt. The hand-tightening bolt passes through the pressing block and is threadedly connected to the buffer hopper. The pressing block is rotatably arranged on the hand-tightening bolt. One end of the pressing block extends to the maintenance door, and the pressing block presses the maintenance door, facilitating the fixation of the maintenance door.

[0017] Through the above technical solutions, the beneficial effects of the present utility model are:

[0018] The structure design of the utility model is reasonable. Compared with the conventional chute structure, a buffer hopper is connected in series on the chute, which is equivalent to adding a buffer function to the chute. Through the buffer hopper, the flow rate of the material can be reduced, the collision force can be reduced, and thus the breakage rate can be reduced. At the same time, the material can be evenly distributed to ensure the uniformity of the feeding of the subsequent equipment.

[0019] In the utility model, two baffle plates arranged in an inverted "eight" shape are arranged in the buffer hopper. When the material flows through the buffer hopper, it will pass through the baffle plates. After being blocked by the baffle plates, the material is buffered, thereby reducing the flow rate of the material and reducing the breakage rate of the material. At the same time, the material flows out evenly between the two baffle plates and in the diversion cavity, and the uniform dispersed flow of the material can be realized, and the dispersed flow avoids gathering together to form a greater impact force.

Detailed Description of the Preferred Embodiments

[0027] The following describes in detail the specific embodiments of the utility model with reference to the drawings:

[0028] As Figures 1 to 6As shown in the figure, the chute device for decelerating and reducing fragmentation includes a chute body 1 and a buffer hopper 2. The chute body 1 is a pipe structure formed by connecting several chute sections arranged in a straight line through flanges. The chute body 1 can be used to convey materials, and the length of the chute body 1 can be specifically selected according to the actual situation.

[0029] A plurality of buffer hoppers 2 are connected in series on the chute body 1. The number of buffer hoppers 2 is determined according to the actual situation. There is a gap between two adjacent buffer hoppers 2, and the plurality of buffer hoppers 2 are arranged at equal intervals, as Figure 1 shown. When the buffer hopper 2 is installed, the chute body 1 and the buffer hopper 2 are connected by flanges, so that the buffer hopper 2 and the chute body 1 are connected and communicated, which is also convenient for the disassembly and assembly of the buffer hopper 2. During the process of the material flowing in the chute body 1, it will be decelerated multiple times by a plurality of buffer hoppers 2, thereby reducing the fragmentation rate of the material.

[0030] The buffer hopper 2 is a hollow pipe structure with openings at both the upper and lower ends. The upper opening of the buffer hopper 2 is a buffer inlet 21, and the lower opening is a buffer outlet 22. The buffer inlet 21 and the buffer outlet 22 are vertically corresponding and communicated. On the left and right sides of the buffer hopper 2, baffle plates 3 are symmetrically arranged. The baffle plates 3 are plate bodies made of non-metallic materials. The two baffle plates 3 on both sides are arranged obliquely in an inverted "eight" shape between the inlet and outlet of the buffer hopper 2, that is, the baffle plates 3 are arranged between the buffer inlet 21 and the buffer outlet 22, as Figure 2 shown. Along the inlet to the outlet of the buffer hopper 2, the distance between the two baffle plates 3 gradually decreases, and a narrow gap is formed between the two baffle plates 3 near the position of the buffer outlet 22.

[0031] The baffle plate 3 is used for buffering the material, which can reduce the flow rate of the material, thereby reducing the wear of the inner wall of the chute body 1. When the baffle plate 3 is installed, the baffle plate 3 is detachably arranged in the buffer hopper 2. Specifically, support plates 4 are symmetrically arranged on the left and right sides in the buffer hopper 2. The two support plates 4 on both sides are arranged in an inverted "eight" shape. The two ends of the support plates 4 are connected and fixed to the side wall of the buffer hopper 2. Each support plate 4 is screwed with a baffle plate 3, realizing the disassembly and assembly of the baffle plate 3. The baffle plate 3 is attached to the support plate 4, and the support plate 4 bears the baffle plate 3.

[0032] In order to improve the bearing capacity of the support plate 4 for the baffle plate 3, a support angle steel 5 is further arranged below each support plate 4. The two ends of the support angle steel 5 are connected and fixed to the side wall of the buffer hopper 2. Under the action of the support angle steel 5, the support strength of the support plate 4 for the baffle plate 3 can be improved, and the ability of the baffle plate 3 to resist the impact of the material can be increased.

[0033] The maximum distance between the two side baffle plates 3 matches the size of the inlet and outlet of the buffer hopper 2. In order to achieve uniform diversion of the material, the left and right side walls of the buffer hopper 2 expand outward in a trapezoidal shape, which can increase the distance between the baffle plate 3 and the side wall of the buffer hopper 2. That is to say, it is equivalent to expanding the width of the buffer hopper 2. Here, the width of the buffer hopper 2 is greater than the size of the inlet and outlet of the buffer hopper 2.

[0034] On the basis of the outward expansion of the side wall of the buffer hopper 2, a diversion cavity 6 is formed between the baffle plate 3 and the left and right side walls of the buffer hopper 2. As a result, the material not only passes through between the two side baffle plates 3, but also passes through the diversion cavity 6, thereby achieving uniform diversion of the material, as Figure 3 shown.

[0035] When manufacturing the chute device: according to the actual application scenario, select the corresponding number of chutes, flange-connect and fix them to form a chute body 1 of a certain length. Then, a plurality of buffer hoppers 2 are flange-connected to the chute body 1, and the buffer hoppers 2 are arranged in sections according to the length of the chute body 1.

[0036] The principle of the present utility model is as follows: during the process of the material flowing in the chute body 1, it will flow through a plurality of buffer hoppers 2. When the material passes through each buffer hopper 2, the material is blocked by the baffle plate 3 arranged in an inverted "V" shape to obtain buffering, thereby reducing the flow rate of the material, greatly reducing the wear of the chute body 1 pipe wall, and increasing the service life.

[0037] At the same time, the baffle plate 3 is made of non-metallic material, with a small impact force on the material, thereby reducing the breakage rate. Finally, a narrow gap is formed between the two side baffle plates 3. When the material passes through this narrow gap, it forms a pile, and then the material can pass through the diversion cavity 6, so that the uniform diversion of the material can be adjusted to form a stable material layer. In this way, the entire chute device has the effects of simple structure, deceleration and breakage reduction, and uniform material flow.

[0038] In order to optimize the product structure and realize the overhaul and maintenance of the components in the buffer hopper 2, a maintenance opening 7 is provided on the side wall of the buffer hopper 2. Through the maintenance opening 7, the baffle plate 3 in the buffer hopper 2 can be taken out. A maintenance door 8 is detachably arranged on the buffer hopper 2, and the maintenance door 8 is used for closing and opening the maintenance opening 7. The maintenance door 8 is a double-layer plate structure. The maintenance door 8 includes an inner layer plate 81 and an outer layer plate 82 that are fixedly attached together. The cross-section of the inner layer plate 81 is adapted to the cross-section of the maintenance opening 7, so that the inner layer plate 81 can be embedded into the maintenance opening 7. The cross-section of the inner layer plate 81 is smaller than the cross-section of the outer layer plate 82, and the outer layer plate 82 fits the outer wall of the buffer hopper 2 to prevent the maintenance door 8 from extending too far into the maintenance opening 7, as Figure 5 and Figure 6 shown.

[0039] In order to lock the maintenance door 8, door lock assemblies 9 for controlling the opening and closing of the maintenance door 8 are also provided on both sides of the buffer hopper 2, as Figure 4As shown in the figure. The door lock assembly 9 includes a pressing block 91 and a hand-tightening bolt 92. The hand-tightening bolt 92 passes through the pressing block 91 and is threadedly connected to the buffer hopper 2. The pressing block 91 is a block with semi-circular ends at both ends, and the sizes of the two ends of the pressing block 91 are different. The pressing block 91 is rotatably arranged on the hand-tightening bolt 92, and one end of the pressing block 91 extends to the inspection door 8.

[0040] When the pressing block 91 is rotated to abut against the inspection door 8 and the hand-tightening bolt 92 is tightened, the inspection door 8 can be pressed by the pressing block 91 to achieve the fixation of the inspection door 8. When the hand-tightening bolt 92 is loosened and the pressing block 91 is rotated in the reverse direction so that it no longer abuts against the inspection door 8, the unlocking of the inspection door 8 can be achieved, and the inspection door 8 can be taken out from the inspection opening 7.

[0041] In order to facilitate the movement of the inspection door 8, a handle 10 is provided on the outer panel 82. The handle 10 is a rod bent in the shape of "[", and it is convenient to move the inspection door 8 into or out of the inspection opening 7 through the handle 10. At the same time, a chain 11 is also provided between the inspection door 8 and the buffer hopper 2 for connection. The chain 11 has a certain length, which neither affects the movement of the inspection door 8 nor causes the inspection door 8 to fall.

[0042] The above embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
