Description

Technical Field

[0001] This utility model relates to the field of chute technology, specifically to an anti-erosion chute. Background Technology

[0002] Chutes are generally used for discharging powdery, granular, and lumpy materials. They are usually installed at the bottom of the hopper or below the discharge port of the conveying device, serving as a material conveying bridge between the hopper or conveying device and the main material handling equipment. Existing chutes are mostly composed of pipes of varying diameters. After material enters the chute from the bottom outlet of the hopper or the discharge port of the conveying device, it causes severe erosion of the pipe body, easily damaging it. This not only affects the smooth operation of production, resulting in losses of manpower and financial resources, but also increases the cost of equipment repair and maintenance.

[0003] For example, patent application number 201720668021.X discloses a chute. This utility model provides a chute including a pipe body with an inlet at the upper end and an outlet at the lower end. An annular baffle is provided between the inlet and outlet within the pipe body. The inner hole of the annular baffle forms a material passage for material to flow from the inlet to the outlet. When material enters the pipe body from the inlet, some material falls onto the annular baffle. This accumulation of material in the annular space formed by the baffle and the pipe body prevents material from approaching the pipe body, causing subsequent material to flow downwards through the inner hole in the center of the baffle. This avoids impact and scouring of the pipe body, extending the chute's service life. However, this chute cannot adjust the interception angle according to the material flow rate when blocking material. If the baffle angle is too small in areas with high flow, it cannot effectively intercept the material; if the baffle angle is too large in areas with low flow, it will excessively intercept material, leading to pipe blockage.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed an anti-scouring chute. Utility Model Content

[0005] The purpose of this invention is to provide an anti-erosion chute to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-erosion chute, comprising a chute body, wherein a plurality of guide grooves are formed at the bottom of the inner surface of the chute body, and a sliding base is slidably installed on the inner surface of the guide grooves; support blocks are provided on both sides of the upper surface of the sliding base, and a rotating rod is rotatably installed on the inner surface of the support blocks; a plurality of positioning holes are uniformly formed on the outer surface of the rotating rod, and a baffle plate is provided on the inner surface of the rotating rod, and the baffle plates are uniformly distributed at the bottom of the inner surface of the chute body.

[0007] Preferably, a gasket is provided on the upper surface of the support block, and a positioning rod is slidably installed through the upper surface of the gasket.

[0008] Preferably, the upper surface of the positioning rod is provided with a rotating cover, and the positioning hole through which the positioning rod passes through the support block and the rotating rod is configured to be slidably connected.

[0009] Preferably, the upper outer surface of the positioning rod is provided with a threaded groove, and the positioning rod is helically connected to the support block through the threaded groove.

[0010] Preferably, the inner wall of the guide groove is provided with connecting pieces on both sides, and the inner surface of the connecting pieces is provided with supporting slide rods.

[0011] Preferably, the support slide rod and the lower surface of the sliding base are configured to be slidably connected, and the outer surface of the support slide rod is provided with a pressure relief spring.

[0012] Preferably, the outer surface of the end of the support slide rod is provided with a second threaded groove, and a spiral pressure sleeve is spirally installed on the outer surface of the second threaded groove.

[0013] Preferably, the spiral sleeve and the pressure relief spring are configured for friction connection, and the pressure relief spring and the lower surface of the sliding base are configured for fixed connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the arrangement of a chute body, guide groove, sliding base, support block, rotating rod, positioning hole, baffle plate, gasket, positioning rod, threaded groove and rotating cover, allows the rotating rod to control the rotation angle of the baffle plate. The baffle plate can be adjusted according to the material, increasing the angle when the material flow rate is too high and decreasing the angle when the material flow rate is too low. This avoids the situation where the material cannot protect the chute body wall due to excessive flow and avoids the situation where the material is blocked due to excessive baffle plate angle when the flow rate is too low.

[0016] 2. This utility model, through the setting of connecting piece, support slide rod, pressure relief spring, threaded groove and spiral pressure sleeve, and the setting of pressure relief spring, can protect the baffle plate and the chute body when the material pressure is too high. The pressure relief spring will drive the baffle plate to slide through the compression characteristic to relieve pressure and protect it, thereby reducing the damage of rigid impact to the chute wall and positioning rod, and extending the overall service life of the equipment.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] like Figures 1-4 As shown, an anti-scouring chute includes a chute body 1. Multiple guide grooves 101 are formed on the bottom of the inner surface of the chute body 1. A sliding base 2 is slidably mounted on the inner surface of the guide grooves 101. Support blocks 201 are provided on both sides of the upper surface of the sliding base 2. A rotating rod 202 is rotatably mounted on the inner surface of the support blocks 201. This technical solution utilizes the rotating rod 202, which can control the rotation angle of the baffle plate 204. The baffle plate 204's blocking angle can be changed according to the material conditions, allowing the angle to be increased where the material flow rate is too high and decreased where the material flow rate is too low. This prevents the material from failing to protect the chute body 1 wall due to excessive flow and avoids material blockage due to an excessively large angle of the baffle plate 204 when the flow rate is too low.

[0025] Furthermore, the outer surface of the rotating rod 202 is evenly provided with a plurality of positioning holes 203, and the inner surface of the rotating rod 202 is provided with a baffle plate 204, which is evenly distributed on the bottom of the inner surface of the chute body 1. In this technical solution, by setting the baffle plate 204, which is installed on the pipe wall of the chute body 1, the material can be intercepted, thereby protecting the pipe wall.

[0026] Furthermore, a gasket 205 is provided on the upper surface of the support block 201, and a positioning rod 206 is slidably installed through the upper surface of the gasket 205. A rotating cover 208 is provided on the upper surface of the positioning rod 206, and the positioning rod 206 is slidably connected through the positioning hole 203 of the support block 201 and the rotating rod 202. With this technical solution, the rotating rod 202 can be limited by sliding limit through the setting of the positioning rod 206.

[0027] Furthermore, the upper outer surface of the positioning rod 206 is provided with a threaded groove 207, and the positioning rod 206 is helically connected to the support block 201 through the threaded groove 207. This technical solution further improves the stability of the installation of the positioning rod 206 through the helically connected method.

[0028] like Figure 5 As shown, connecting pieces 3 are provided on both sides of the inner wall of the guide groove 101, and a support slide rod 301 is provided on the inner surface of the connecting piece 3. In this technical solution, the pressure relief spring 302 can be positioned and limited by the setting of the support slide rod 301.

[0029] Furthermore, the lower surface of the support slide rod 301 and the sliding base 2 are configured to be slidably connected, and the outer surface of the support slide rod 301 is provided with a pressure relief spring 302. With this technical solution, the pressure relief spring 302 can protect the baffle plate 204 and the chute body 1 when the material pressure is too high. The pressure relief spring 302 will drive the baffle plate 204 to slide through the compression characteristics to relieve pressure and protect it, thereby reducing the damage of rigid impact to the chute wall and the positioning rod 206 and extending the overall service life of the equipment.

[0030] Furthermore, the outer surface of the end of the support slide bar 301 is provided with a threaded groove 303, and a spiral sleeve 304 is spirally installed on the outer surface of the threaded groove 303. The spiral sleeve 304 and the pressure relief spring 302 are configured to be in frictional connection, and the pressure relief spring 302 and the lower surface of the sliding base 2 are configured to be in fixed connection. In this technical solution, by setting the spiral sleeve 304, the rebound threshold of the pressure relief spring 302 can be adjusted by pressing the spiral sleeve 304 in a spiral manner according to different material feeding conditions.

[0031] Working principle: When using this anti-erosion chute, firstly, before the chute body 1 is put into use, the angle of the baffle plate 204 needs to be precisely adjusted by rotating the rotating rod 202 on the inner surface of the support block 201 according to the preset installation position of the baffle plate 204. After adjustment, the positioning rod 206 is first inserted into the positioning hole 203 on the outer surface of the rotating rod 202 in a sliding manner, and then the rotating cover 208 is rotated so that the positioning rod 206 with the threaded groove 207 forms a spiral connection with the support block 201, thereby achieving a firm fixation of the baffle plate 204.

[0032] After angle adjustment and fixing, the support slide rod 301 with connecting piece 3 is installed into the guide groove 101 on the inner wall of the chute body 1 to complete the overall assembly. In actual installation, according to the flow distribution characteristics inside the chute body 1, the baffle plate 204 with a larger angle is installed in the area with a larger flow, and the baffle plate 204 with a smaller angle is installed in the area with a smaller flow.

[0033] This design can both intercept materials through the baffle plate 204 during the material feeding process of the chute body 1, preventing them from directly scouring the chute wall and playing a protective role, and guide the flow of materials through reasonable angle settings to prevent material accumulation and blockage of the chute body 1.

[0034] If the impact force of the material during feeding is too great and exceeds the protection threshold of the pressure relief spring 302, the pressure relief spring 302 will drive the sliding base 2 to slide along the guide groove 101 through compression, thereby buffering the impact force and protecting the chute wall and positioning rod 206, effectively extending the service life of the equipment. This is the working principle of the anti-erosion chute.
