Description

Technical Field

[0001] The utility model relates to the technical field of auger feeding, in particular to an auger feeding device for a slipform paver. Background Art

[0002] The auger feeder is an important material transport and unloading component in the slipform paver. The existing auger feeder has a discharge pipe (or discharge port) where materials, especially concrete mixture, are often dumped. If it is not cleaned in time, the concrete mixture will easily adhere to the wall of the material guide trough. When encountering high temperature weather, it is easy to solidify and only adhere to the trough wall. Over time, it is not only difficult to clean, but also leads to slow discharge speed, affecting the paving effect.

[0003] In the existing material guide trough, if it is an open structure, the material guide trough is generally washed with a water gun after the material is laid to wash the material down. When the material is already adhered to the trough wall, a shovel is used to scrape off the adhered material. Although most of the adhered material can be removed, the trough wall is easily damaged during the shoveling process.

[0004] How to design an auger feeding device for a slipform paver with a reasonable structure, ingenious design, and the ability to clean concrete materials adhered to the inner wall of the material guide trough in time, with a fast cleaning speed and good cleaning effect, saving manpower and material resources, and improving production efficiency is a problem that needs to be solved at present. Utility Model Content

The auger blades continuously transport concrete to the opening of the discharge port at the upper end of the auger feeding device to prepare for discharge. The residual concrete material in the material guide trough is cleaned in time after discharge through the residual material cleaning mechanism to avoid caking affecting discharge.

[0008] The above is the basic implementation mode of the utility model, and further improvements, perfections and limitations can be made on the above basis: as described, the residual material cleaning mechanism includes two piston columns, a hydraulic cylinder, a scraper head and a control valve, the column head of the piston column is fixedly installed on the back of the scraper head, the fixed end of the hydraulic cylinder is fixed on the housing of the auger feeding device, the hydraulic cylinder is connected to the external hydraulic pipeline, and the control valve controls the piston column to drive the scraper head to retract the scraper to scrape off the residual concrete material on the wall of the material guide trough and clean it.

[0009] The above is the basic implementation mode of the utility model, and further improvements, perfections and limitations can be made on the above basis: for example, the longitudinal section of the scraper head is a right-angled triangle section, and the scraper head is made of wear-resistant metal material to avoid the scraper head being scratched by concrete when scraping.

DETAILED DESCRIPTION

[0020] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the auger feeding device for the slipform paver includes a driving motor 1, an auger frame 2, a steering cylinder 3, a telescopic cylinder 4, an auger shaft 5, an auger blade 6, a motor 7, a discharge port 8, a residual material cleaning mechanism 9 and a material guide trough 10. The auger feeding device is arranged as a whole at an angle upward on one side of the body of the slipform paver. The inlet end of the discharge port 8 is fixed to the lower edge of the end of the auger feeding device. The motor 7 drives the driving motor 1 to control the rotation of the auger shaft 5. The auger blade 6 continuously transports concrete to the opening of the discharge port 8 at the upper end of the auger feeding device to prepare for discharge. The residual concrete material after discharge from the material guide trough 10 is cleaned in time by the residual material cleaning mechanism 9 to avoid caking affecting discharge.

[0022] like Figure 4 and 5 As shown, the residual material cleaning mechanism 9 is arranged behind the discharge port 8, and a space is left between the residual material cleaning mechanism 9 and the discharge port 8 to prevent concrete material from falling on the residual material cleaning mechanism 9 when the discharge port 8 is normally discharged.

[0023] like Figure 3 As shown, the residual material cleaning mechanism 9 includes two piston columns 901, a hydraulic cylinder 902, a scraper head 903 and a control valve. The column head of the piston column 901 is fixedly installed on the back of the scraper head 903, the fixed end of the hydraulic cylinder 902 is fixed on the housing of the auger feeding device, and the hydraulic cylinder 902 is connected to the external hydraulic pipeline. The control valve controls the piston column 901 to drive the scraper head 903 to retract the scraper to scrape and clean the residual concrete material on the wall of the material guide trough 10.

[0024] The longitudinal section of the scraper head 903 is a right-angled triangle section, and the scraper head 903 is made of wear-resistant metal material to prevent the scraper head 903 from being scratched by concrete during scraping.

[0025] As shown in the figure, the actual working process of the utility model is as follows:

[0026] The motor 7 drives the driving motor 1 to control the rotation of the auger shaft 5, and the auger blades 6 continuously transport the concrete to the opening of the discharge port 8 at the upper end of the auger feeding device to prepare for discharge. At this time, the residual material cleaning mechanism 9 does not work, and the piston column 901 is in a retracted state (such as Figure 4 As shown in FIG. 1 ), the concrete mixture begins to be discharged normally; when the discharge is completed, the residual material cleaning mechanism 9 starts to work, and the worker controls the piston rod 901 to extend outwards through the control valve (as shown in FIG. 1 ). Figure 5 As shown), the scraper head 903 is driven to extend the scraper to scrape off the residual concrete material on the wall of the guide trough 10 for cleaning. If the cleaning is not thorough once, the control valve can be repeatedly operated to make the telescopic scraper head scrape and clean the wall of the guide trough 10 until it is clean.

[0027] The utility model discloses cleaning the concrete material on the inner wall of the guide trough in time, has a fast cleaning speed and a good cleaning effect, saves manpower and material resources, improves production efficiency, and solves the technical problems that the material is easily adhered to the wall of the guide trough when the auger feeder of the existing slipform paver is unloaded by the auger, and the wall of the guide trough is easily damaged when the adhesion is shoveled away, which is time-consuming and labor-intensive, and seriously affects production efficiency. Compared with the existing technology, it has a good market prospect and development space.
