Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cleaning devices for feed pipes, specifically a cleaning device for feed pipes. Background Technology
[0002] The cleaning device for the feed pipe ensures smooth conveying by efficiently removing accumulated material. Common cleaning devices include mechanical cleaning devices, pneumatic cleaning devices, hydraulic cleaning devices, and ultrasonic cleaning devices. Mechanical cleaning devices directly remove accumulated material from the pipe wall through mechanical contact and are suitable for materials with high viscosity, high hardness, or firm accumulation. These include rotary scraper cleaning devices, telescopic blockage removers, and vibration cleaning devices. Among them, rotary scraper cleaning devices remove adhering materials by contacting the inner wall with a rotating scraper, and their power source is usually an electric motor or pneumatic motor.
[0003] The cleaning structure of the existing rotary scraper cleaning device consists of a scraper body and a blade holder. The scraper body is centrally symmetrically mounted on the blade holder, and the end of the blade holder is connected to the power source. When in use, the cleaning structure needs to be inserted into the discharge pipe, and then the power source is started to drive the scraper body to rotate. The cleaning structure travels in the discharge pipe to clean the accumulated material on the inner wall of the discharge pipe.
[0004] In practical use, the effective cleaning length of the scraper needs to be strictly matched with the inner diameter of the pipe. For cleaning different pipe diameters, multiple scrapers need to be adjusted separately, and it cannot be guaranteed that the adjustment distance of each scraper is the same. There are cases where the scraper adjustment distance is too large or too small, causing some scrapers to be suspended in the air. Moreover, the adjustment of multiple scrapers requires disassembling the fixing bolts, which makes the adjustment process cumbersome. Therefore, a cleaning device for the feed pipe is proposed to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a cleaning device for a feed pipe, which has the advantage of adaptively adjusting the distance between the scraper and the pipe wall. This solves the problem that the effective cleaning length of the scraper must be strictly matched with the inner diameter of the pipe. If the pipe is large diameter, the original scraper length is insufficient, resulting in a large distance between the scraper and the pipe wall, which will form a ring-shaped uncleaned area on the pipe wall, and the material will gradually accumulate. If the pipe is small diameter, the scraper length is too long, causing the scraper to directly contact the pipe wall. During rotation, it will rigidly collide with the pipe wall, causing the blade to break, the pipe wall to be scratched, and even the motor to be overloaded due to excessive resistance.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for a feed pipe, comprising a blade holder cylinder mounted on the cleaning device, wherein a scraper structure is provided on the blade holder cylinder;
[0007] The scraper structure includes a blade body component disposed on a blade holder cylinder. A support component connected to the blade body component is disposed inside the blade holder cylinder. A linkage component for driving the blade body component to move is disposed inside the blade holder cylinder. A control component for controlling the linkage component to move along the axial direction of the blade holder cylinder is disposed inside the blade holder cylinder.
[0008] The blade body component includes a scraper blade, the front end of which is provided with a material breaking head, and a limiting plate that extends through the inside of the blade holder cylinder is provided on the scraper blade, and an inclined groove is provided inside the limiting plate;
[0009] The linkage component includes a connecting seat, on which a pin is fixedly installed, and one end of the pin passes through an inclined groove;
[0010] The support component includes a mounting base fixedly installed inside the blade holder cylinder, and a connecting rod is hinged to the mounting base, with one end of the connecting rod hinged to the scraper blade.
[0011] Furthermore, the tool holder cylinder is provided with a guide groove that slides in connection with the limiting plate, and the tool holder cylinder is provided with a storage groove for storing the connecting rod.
[0012] Furthermore, the control component includes a threaded rod rotatably mounted inside the tool holder cylinder, and the threaded rod is threadedly connected to the connecting seat. The end of the threaded rod is rotatably connected to the mounting seat, and a quincunx block is fixedly mounted on the front end of the threaded rod.
[0013] Furthermore, the number of the blade body components is four, and they are symmetrically distributed around the central axis of the blade holder cylinder. The number of the guide groove, storage groove, limiting plate, inclined groove, pin, and connecting rod is the same as the number of blade body components.
[0014] Furthermore, cover plates are fixedly installed at both the front and rear ends of the tool holder cylinder, and a connector for connecting the drive source is fixedly installed on the front cover plate.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] 1. This cleaning device for the feed pipe utilizes a transmission system consisting of control components, linkage components, and support components to achieve dynamic adjustment of the scraper length. This avoids the limitations of existing scrapers that cannot be adjusted synchronously and have a cumbersome adjustment process. As a result, this device can be adapted to cleaning feed pipes of various diameters, reducing equipment redundancy. Furthermore, the wedge-shaped design of the crushing head can effectively improve the crushing efficiency of agglomerated materials and prevent the scraper from jamming due to excessive resistance.
[0017] 2. The cleaning device for the discharge pipe uses a combination design of guide groove and storage groove to restrict the position of the connecting rod and the limiting plate, preventing the scraper blade from shaking during the rotation cleaning process. It can also store the connecting rod and the limiting plate inside the blade holder cylinder, reducing the space occupied inside the discharge pipe.
[0018] 3. The cleaning device for the feed pipe has four sets of blade components that are centrally symmetrically distributed to form a stable structure with four-point support, which enhances the uniformity of cleaning and structural stability. Moreover, each set of blade components does not affect each other. When a single set of scrapers fails, the other three sets can still maintain the cleaning operation. Attached Figure Description

[0025] 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.
[0026] Example 1: Please refer to Figure 1-5The cleaning device for a feed pipe in this embodiment includes a knife holder cylinder 1 installed on the cleaning device. A scraper structure 2 is provided on the knife holder cylinder 1. Cover plates are fixedly installed at both the front and rear ends of the knife holder cylinder 1. A connector 3 for connecting a drive source is fixedly installed on the front cover plate.
[0027] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the scraper structure 2 includes a blade body component 21 disposed on the blade holder cylinder 1, a support component 22 connected to the blade body component 21 disposed inside the blade holder cylinder 1, a linkage component 23 for driving the blade body component 21 to move disposed inside the blade holder cylinder 1, and a control component 24 for controlling the linkage component 23 to move along the axial direction of the blade holder cylinder 1 disposed inside the blade holder cylinder 1.
[0028] The blade body component 21 includes a scraper blade 211, a material breaking head 212 is provided at the front end of the scraper blade 211, and a limiting plate 213 is provided on the scraper blade 211 that extends into the inside of the blade holder cylinder 1. An inclined groove 214 is provided inside the limiting plate 213.
[0029] The linkage component 23 includes a connecting seat 231, on which a pin 232 is fixedly installed, and one end of the pin 232 passes through the inclined groove 214;
[0030] The support component 22 includes a mounting base 221 fixedly installed inside the blade holder cylinder 1. A connecting rod 222 is hinged to the mounting base 221, and one end of the connecting rod 222 is hinged to the scraper blade 211.
[0031] The tool holder cylinder 1 has a guide groove 11 that is slidably connected to the limiting plate 213, and a storage groove 12 for storing the connecting rod 222. The combination design of the guide groove 11 and the storage groove 12 can restrict the position of the connecting rod 222 and the limiting plate 213, avoid the scraper blade 211 from shaking during the rotation cleaning process, and can store the connecting rod 222 and the limiting plate 213 inside the tool holder cylinder 1, reducing the space occupied inside the discharge tube.
[0032] In addition, there are four blade body components 21, which are symmetrically distributed along the central axis of the blade holder cylinder 1. The number of guide grooves 11, storage grooves 12, limiting plates 213, inclined grooves 214, pins 232 and connecting rods 222 are the same as the number of blade body components 21. The four sets of blade body components 21 are centrally symmetrically distributed to form a stable structure with four-point support, which enhances the uniformity of cleaning and structural stability. Moreover, each set of blade body components 21 does not affect each other. When a single set of scrapers fails, the other three sets can still maintain cleaning work.
[0033] Using the above technical solution, the connecting seat 231 is controlled to move axially along the blade holder cylinder 1 by the control component 24, while the pin 232 of the connecting seat 231 slides in the inclined groove 214 of the scraper blade 211, converting the axial movement into the radial expansion of the scraper blade 211. The connecting rod 222 of the support component 22 expands synchronously with the movement of the scraper blade 211, thereby adjusting the distance between the scraper blade 211 and the inner wall of the straight drop pipe to adapt to straight drop pipes of different diameters. The crushing head 212 of the scraper blade 211 crushes hard block accumulations, and the scraper body scrapes off the attachments on the pipe wall. At the same time, the guide groove 11 restricts the movement trajectory of the limiting plate 213 to ensure movement accuracy.
[0034] Example 3: Please refer to Figure 1-5 Based on Embodiment 2, the control component 24 includes a threaded rod 241 rotatably installed inside the tool holder cylinder 1, and the threaded rod 241 is threadedly connected to the connecting seat 231. The end of the threaded rod 241 is rotatably connected to the mounting seat 221, and a quincunx block 242 is fixedly installed on the front end of the threaded rod 241.
[0035] Using the above technical solution, the plum blossom block 242 of the rotation control component 24 drives the threaded rod 241 to rotate, thereby controlling the connecting seat 231 to move axially along the tool holder cylinder 1, thereby achieving high-precision adjustment of the distance between the scraper blade 211 and the inner wall of the straight drop tube.
[0036] The working principle of the above embodiments is as follows:
[0037] In use, the initial state of the scraper structure 2 of the cleaning device for the feed pipe is that the scraper blade 211 is in close contact with the outer surface of the blade holder cylinder 1.
[0038] The swivel block 242 of the rotation control component 24 drives the threaded rod 241 to rotate, thereby controlling the connecting seat 231 to move axially along the tool holder cylinder 1. The pin 232 of the connecting seat 231 slides in the inclined groove 214 of the scraper blade 211, converting the axial movement into the radial expansion of the scraper blade 211. The connecting rod 222 of the support component 22 expands synchronously with the movement of the scraper blade 211, thereby adjusting the distance between multiple scraper blades 211 and the inner wall of the straight drop pipe to adapt to straight drop pipes of different diameters.
[0039] The drive source drives the knife holder cylinder 1 to rotate, the crushing head 212 of the scraper blade 211 crushes the hard block of material, the scraper body scrapes off the attachments on the pipe wall, and at the same time the guide groove 11 restricts the movement trajectory of the limit plate 213 to ensure movement accuracy.
