Detailed implementation manners

[0031] The following is further detailed description of the present application in conjunction with Figures 1-5 to make the technical solution of the present application easier to understand and master.

[0032] An embodiment of the present application discloses a vacuum brick extruder.

[0033] Referring to Figures 1-5 , a vacuum brick extruder in this embodiment includes a machine body 1 and an extrusion head 11. The extrusion head 11 is fixedly connected to the machine body 1. It further includes a forming structure 2 for forming the mud strip. The forming structure 2 includes a mounting plate 21, four sliding plates 22 and an adjusting member 23. The mounting plate 21 is fixedly connected to the extrusion head 11. The four sliding plates 22 are respectively slidably connected to the mounting plate 21 along the direction perpendicular to the extrusion direction of the mud strip. Two of them slide vertically, and the other two slide horizontally. And the two horizontally - sliding plates 22 and the two vertically - sliding plates 22 are arranged alternately. The four sliding plates 22 are evenly distributed around the peripheral side of the mounting plate 21. The four sliding plates 22 together form an opening 25 for the mud strip to be extruded. The adjusting member 23 is used to drive the movement of the four sliding plates 22 respectively.

[0034] Referring to Figures 1-5 , when the mud strip is extruded from the opening 25, the multiple sliding plates 22 simultaneously limit the extrusion of the mud strip and scrape the side surface of the mud strip, so that the mud strip reaches the rated cross - sectional dimension; by driving the movement of the multiple sliding plates 22 respectively through the adjusting member 23, the positions of the multiple sliding plates 22 on the mounting plate 21 are adjusted, thereby adjusting the shape of the opening 25, that is, adjusting the end - face specification of the brick blank; making the brick extruder convenient for the production of brick blanks with different cross - sectional specifications.

[0035] Referring to Figures 1-5, the adjusting member 23 includes four threaded rods 231. The four threaded rods 231 respectively correspond to the four sliding plates 22. The four threaded rods 231 are respectively rotatably connected to the frame along the sliding directions of the corresponding sliding plates 22. One ends of the four threaded rods 231 respectively penetrate and are threadedly connected to the corresponding sliding plates 22, and the four threaded rods 231 respectively penetrate and are slidably connected to another sliding plate 22 with the same sliding direction. One end of the threaded rod 231 penetrates the mounting plate 21 to the outside. Coaxially and fixedly connected to the four threaded rods 231 are force-applying blocks 232. The force-applying blocks 232 are located at the ends of the threaded rods 231 that penetrate to the outside. The force-applying blocks 232 are provided with a plurality of through holes 242 that can be inserted and matched with the insertion rods 241. The plurality of through holes 242 are evenly distributed around the circumferential side surface of the force-applying block 232. Further included is a locking member 24. The locking member 24 is used to limit the rotation of the threaded rod 231. The locking member 24 includes an insertion rod 241. The insertion rod 241 is movably connected to the mounting plate 21. The insertion rod 241 can be inserted and matched with the coaxial through holes 242 on a plurality of force-applying blocks 232 at the same time.

[0036] Referring to Figures 1-5 , when it is necessary to rotate the force-applying block 232, the insertion rod 241 can also be inserted and matched with any one of the through holes 242 on the force-applying block 232, and the force-applying block 232 is rotated by applying force to the insertion rod 241. By applying force to the force-applying block 232, the threaded rod 231 is rotated. Through the threaded connection between the threaded rod 231 and the sliding plate 22, the sliding plate 22 slides along the axial direction of the threaded rod 231 to adjust the position of the sliding plate 22 on the mounting plate 21, thereby adjusting the shape of the opening 25, that is, adjusting the end face specifications of the brick blank, so that the brick extruder is convenient for the production of brick blanks with different cross-section specifications. The insertion rod 241 is inserted and matched with the coaxial through holes 242 on a plurality of force-applying blocks 232 at the same time, and the insertion rod 241 limits the rotation of a plurality of force-applying blocks 232 at the same time, so as to limit the rotation of a plurality of threaded rods 231, reducing the possibility that the movement of the sliding plate 22 during the working process of the brick extruder affects the brick blank specifications.

[0037] Referring to Figure 1 , Figure 4 and Figure 5 , the distance from one end of the four sliding plates 22 close to the extrusion head 11 to the center of the extrusion head 11 gradually becomes closer from the end far from the extrusion head 11. One end of the four sliding plates 22 close to the center of the extrusion head 11 is arranged in an inclined plane. The brick extruder extrudes the mud strip from the opening 25 formed by the plurality of sliding plates 22 through extrusion, which is convenient for scraping the side surface of the mud strip so that the cross-section of the mud strip has a rated size.

[0038] Referring to Figure 1 , Figure 4 and Figure 5, scraping blades 221 are fixedly connected to the opposite ends of the four sliding plates 22 respectively. When the clay strip is extruded, the scraping blades 221 abut against the peripheral side surfaces of the clay strip. By providing the scraping blades 221, the side surfaces of the clay strip are scraped, and at the same time, the irregular hard layers on the peripheral side surfaces of the clay strip are shaved off, making the side surfaces of the clay strip smoother and more polished.

[0039] Refer to Figure 1 , Figure 4 and Figure 5 , it further includes four groups of spray heads 12 and water pipes 13. The four groups of spray heads 12 respectively correspond to the four sliding plates 22. The four groups of spray heads 12 are respectively fixedly connected to one end of the corresponding sliding plate 22 close to the center of the extrusion head 11. The multiple groups of spray heads 12 are respectively communicated with the water pipe 13, and the water pipe 13 is communicated with a water source. Through the water pipe 13 and the spray heads 12, water flows through the sliding plate 22 to humidify the clay material passing through the sliding plate 22, reducing the loss of moisture in the clay material, and the possibility that the brick blank coming out from the opening 25 cracks.

[0040] Refer to Figures 1-5 , scale values 222 are marked on the mounting plate 21. The middle of the mounting plate 21 is the zero scale. By providing the scale values 222 on the mounting plate 21, it is convenient for the operator to adjust the position of the sliding plate 22.

[0041] Of course, the above are only typical examples of the present application. In addition, the present application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
