Description

Technical Field

[0001] This invention relates to the technical field of brick-making equipment, and in particular to a material feeding trolley for a brick-making machine. Background Technology

[0002] Currently, brick-making machines are mechanical devices used to produce masonry blocks. They typically use stone powder, fly ash, slag, mineral slag, crushed stone, sand, and water as raw materials, and process them through mixing, extruding brick blanks, drying, baking, and sintering to produce masonry blocks. To make the masonry blocks more compact, a brick-making press head is generally used to press the brick blanks into shape. Now, there is a need to manufacture a double-layer brick, which is formed by pressing two layers of materials: a base material and a surface material. In the pressing process, the base material is first placed in the brick-making mold, and the brick-making machine press head performs the first pressing. Then, the surface material is placed on top of the base material, and the brick-making machine press head performs a second pressing to form the double-layer brick. However, existing brick-making machines have the following disadvantages in the material distribution process:

[0003] 1. In existing brick-making machines, when the material placing trolley is placing material above the brick mold, the trolley and its base plate first move together to one side of the mold. Then, the base plate rests against one side of the mold and remains stationary. The trolley then moves upwards to place the material. Because the base plate and the material frame of the trolley are matched, the front end of the material frame and the front end of the base plate are aligned. However, in actual operation, the trolley may move towards the mold before the base plate rests against it, causing material to leak from the gap between the base plate and the mold, affecting the placement effect.

[0004] 2. Existing brick making machines generally use the brick making machine head to flatten the material in the brick making mold. The brick making machine head can only flatten the material in the vertical direction. If the material at the front and rear ends or left and right ends of the brick making mold is not flat, the flattening effect of using the brick making machine head to flatten the material is not good, and it is time-consuming and labor-intensive, which is not conducive to efficient brick production.

[0005] 3. After the first pressing of the base material, the existing brick-making machine's press head will have base material stuck to it. If the second pressing of the fabric is carried out directly, the base material will be mixed on the surface of the fabric, affecting the forming effect of the fabric layer. Therefore, after the first pressing of the brick-making machine's press head, the base material on the press head needs to be cleaned, which increases the operator's workload and affects the production efficiency of brick making.

[0006] 4. In existing brick-making machines, when the base material is laid out, the height of the base material within the brick-making mold cannot be uniform after the brick-making press head flattens the base material. This results in different height ratios between the base material layer and the surface layer of the produced double-layer bricks, affecting the production quality of the bricks.

[0007] In view of this, the inventor, in order to address the many shortcomings and inconveniences caused by the imperfections in the above-mentioned fabric cart structure design, has deeply conceived, actively researched, improved and tested, and developed this invention. Summary of the Invention

[0008] The purpose of this invention is to provide a material placing trolley for a brick making machine. There is a certain distance between the front end of the bottom plate of the material placing trolley and the front end of the material frame of the material placing trolley. This ensures that before the front end of the material frame of the material placing trolley comes into contact with the top of the brick making mold, the front end of the bottom plate of the material placing trolley is already in contact with one side of the brick making mold, thus preventing material from leaking out of the gap between the front end of the bottom plate of the material placing trolley and the brick making mold.

The oblique part is provided with a plurality of first locking holes. The front panel of the outer frame is provided with a second locking hole corresponding to the first locking hole. A fourth bolt passes through the first locking hole and is locked in the second locking hole, pressing the oblique part to tilt and clamp the base material cleaning brush.

[0020] The base material collection trough is equipped with a baffle on the side near the fabric cart frame to prevent base material from falling into the fabric cart frame.

Detailed Implementation

[0035] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0036] Please see Figures 1 to 10This invention relates to a material placing trolley for a brick making machine. The material placing trolley has a material placing frame 1 and a material placing trolley base plate 2, with a gap between the front end of the material placing frame 1 and the front end of the material placing trolley base plate 2. When the material is placed, the material placing frame 1 and the material placing trolley base plate 2 move together toward the brick making mold. Since there is a certain distance between the front end of the material placing trolley base plate 2 and the front end of the material placing frame 1, it can be ensured that before the front end of the material placing frame 1 comes to abut against the top of the brick making mold, the front end of the material placing trolley base plate 2 has already abutted against one side of the brick making mold, thus preventing material leakage from the gap between the front end of the material placing trolley base plate 2 and the brick making mold.

[0037] The lower part of the front end of the fabric cart frame 1 of the present invention is provided with a support base 3. The support base 3 has a transverse plate 31 that is locked to the fabric cart frame 1 and two extension plates 32 that extend outward from both ends of the transverse plate 31. A pressure roller 33 located within the spacing between the two extension plates 32 is pivotally connected. The pressure roller 33 is connected to a drive mechanism 34 that drives the pressure roller 33 to roll. The pressure roller 33 is provided at the front end of the fabric cart frame 1. When the fabric cart frame 1 moves forward or backward above the brick making mold to spread the material, the rolling of the pressure roller 33 can roll and flatten the material inside the brick making mold. Therefore, before the brick making head presses, the pressure roller 33 can be used to flatten the material at the front and rear ends or left and right ends of the brick making mold, resulting in good brick forming effect and improved production efficiency.

[0038] The bottom side of the pressure roller 33 of the present invention is slightly higher than the bottom side of the front side plate 11 of the fabric cart frame 1, so as to avoid the pressure roller 33 pressing against the fabric cart bottom plate 2, and prevent the pressure roller 33 from constantly pressing against the fabric cart bottom plate 2 and causing mutual wear, which would affect the service life of both.

[0039] The horizontal plate 31 of the present invention is provided with a plurality of horizontally arranged and vertically arranged elongated holes, and the front side plate 11 of the fabric cart frame 1 is provided with through holes corresponding to the elongated holes; the first bolt passes through the through hole and the elongated hole and cooperates with the first nut to lock the horizontal plate 31 and the front side plate 11 together; the support base 3 is adjusted up and down through the structure of the elongated hole and the first bolt, so as to adjust the height of the pressure roller 33; when the fabric is laid, the height of the pressure roller 33 can be adjusted according to the different fabric heights, and the pressing and flattening effect is better.

[0040] The top surface of the transverse plate 31 of the present invention is symmetrically provided with two recessed grooves 312, and the outer side of the transverse plate 31 is provided with a first limiting block 313 extending outward on one side of the bottom of the recessed groove 312; the front side plate 11 of the fabric cart frame 1 is provided with a second limiting block 112 that passes through the recessed groove 312 and is parallel to the first limiting block 313, and the first limiting block 313 and the second limiting block 112 are respectively provided with locking holes for locking the second bolt 1121; when the first limiting block 313 on the transverse plate 31 abuts against the bottom surface of the second limiting block 112, the second limiting block 112 can limit the support seat 3 to be set at the highest position of the front side plate 11, thereby limiting the highest position of the pressure roller 33, and preventing the pressure roller 33 from being too high and losing its pushing function.

[0041] The pressure roller 33 of the present invention has a scraper 35 on the side facing away from the material frame 1 of the fabric cart. Two U-shaped seats 314 are symmetrically arranged on the transverse plate 31. A connecting rod 315 is pivotally connected to each of the two U-shaped seats 314. The other end of the two connecting rods 315 is connected to a reinforcing rod 316. The reinforcing rod 316 is provided with a plurality of first screw holes 3161. The scraper 35 is provided with a second screw hole 351 corresponding to the first screw holes 3161. A third bolt 352 is locked into the second screw hole 351 and the first screw hole 3161 to lock the scraper 35 onto the reinforcing rod 316. The reinforcing rod 316 is arranged perpendicular to the scraper 35. The scraper 35 has a scraping end 353 that abuts against the outer ring of the pressure roller 33. When the pressure roller 33 rolls and pushes the material, the scraper 35 can scrape off the material stuck to the pressure roller 33 in time, resulting in a better leveling effect.

[0042] The drive mechanism 34 of the present invention includes a motor 341 disposed on the side of the fabric carriage 1 away from the pressure roller 33, a drive gear 343 disposed on the output shaft 342 of the motor 341, a transmission shaft 344, a first transmission gear 345, two second transmission gears 346, two third transmission gears 347, a first chain, and a second chain. The transmission shaft 344 is arranged parallel to the pressure roller 33. The first transmission gear 345 is disposed on the transmission shaft 344 and located inside the fabric carriage 3, and is connected to the drive gear 343 via the first chain. The two second transmission gears 346 and the second chain are also present. Gears 346 are located at both ends of the transmission shaft 344 that extend beyond the two side plates of the fabric cart frame 1. The pressure roller 33 has shaft portions extending beyond the extension plates at both ends. The two third transmission gears 347 are located on the two shaft portions and are connected to the second transmission gear 346 via a second chain. The drive mechanism 34 can drive the pressure roller 33 to roll and flatten the material. The drive mechanism 34 of the pressure roller 33 is located on the other side of the fabric cart frame 1. The drive mechanism 34 of the pressure roller 33 and the drive mechanism of the material raking mechanism in the fabric cart can share a single drive motor 341, which is more energy-efficient and environmentally friendly.

[0043] The fabric frame 1 of the present invention has an inner frame 12 and an outer frame 13. The inner frame 12 has two outwardly extending first winglets 121 on each of its two side plates. The outer frame 13 has two outer frame side plates located outside the two side plates. Each outer frame side plate has two second winglets 131 arranged parallel to the two first winglets 121. The first winglet 121 has a guide hole and two first through holes located on both sides of the guide hole. The second winglet 131 has locking holes corresponding vertically to the guide hole and two second through holes corresponding to the first through holes. One end of a guide bolt 14 passes through the first guide hole and is locked in the locking hole. The upper end of a positioning bolt 15 passes through the first through hole and is locked to the first winglet by a nut. Above 121, the lower end of the positioning bolt 15 passes through the second through hole and is locked to the lower part of the second wing 131 by a nut; a spring 151 is sleeved on the positioning bolt 15, and the lower end of the spring 151 abuts against the top surface of the first wing 121, and the upper end of the spring 151 abuts against the bottom surface of the nut located above the positioning bolt 15; when the inner frame 12 of the fabric carriage is supported upward by the fabric carriage bottom plate 2, the first wing 121 moves upward and compresses the spring 151; when the inner frame 12 of the fabric carriage is not supported by the fabric carriage bottom plate 2, the restoring force of the spring 151 pushes the first wing 121 downward, thereby driving the inner frame 12 downward, so that the inner frame 12 floats up and down on the outer frame 13.

[0044] The upper part of the front end of the fabric cart frame 1 of the present invention is provided with a base material collection groove 4; the front end of the outer frame 13 is provided with an outer frame front plate 132 that connects the two outer frame side plates and spans the base material collection groove 4, and a base material cleaning brush 5 is provided on the outer frame front plate 132, and the top surface of the base material cleaning brush 5 protrudes from the top surface of the base material collection groove 4; when the fabric cart moves forward or backward above the brick making mold to spread the material, the base material cleaning brush 5 can clean the base material adhering to the bottom surface of the brick making head above and sweep the base material into the base material collection groove 4; not only can the base material on the brick making head be cleaned, but the base material can also be collected, so as not to mix the base material and the fabric, resulting in a better spreading effect, a cleaner fabric surface of the double-layer brick, and improved production quality.

[0045] The base material collection trough 4 of the present invention is a rectangular trough formed by a front end plate 41, a rear end plate 42, and two side end plates 43. The front end plate 41 is higher than the rear end plate 42, and the side end plates 43 have a first straight portion 431 connected to the front end plate 41, a second straight portion 432 connected to the rear end plate 42, and an inclined portion 433 connecting the first straight portion 431 and the second straight portion 432; the outer frame front plate 132 is located above the second straight portion 432; the front end plate 43 of the base material collection trough 4 1 is higher than the rear end plate 432, and the base material cleaning brush 5 is close to the rear end plate 432. The base material collection trough 4 has a large space in front of the base material cleaning brush 5 and a small space behind the base material cleaning brush 5. When the material placing vehicle moves forward to place the material, it drives the base material cleaning brush 5 to remove most of the base material on the bottom surface of the brick pressing head. Most of the base material is swept into the base material collection trough 4 in front of the base material cleaning brush 5. Then, when the material placing vehicle moves backward to place the material, a small part of the base material is swept into the base material collection trough 4 behind the base material cleaning brush 5, which can better collect the base material.

[0046] The outer frame front plate 132 of the present invention is provided with a locking plate. The bottom end of the locking plate has a transverse portion 1331 that abuts against the side of the outer frame front plate 132 and an oblique portion 1332 located on one side of the base material cleaning brush 5. The oblique portion 1332 is provided with a plurality of first locking holes 1333. The outer frame front plate 132 is provided with a second locking hole 1321 corresponding to the first locking holes 1333. A fourth bolt 1322 passes through the first locking hole 1333 and is locked in the second locking hole 1321, pressing the oblique portion 1332 to tilt and clamp the base material cleaning brush 5. The bottom end of the base material cleaning brush 5 is fitted with a U-shaped clamp 134. The U-shaped clamp 134 has a clamping function. The base material cleaning brush 5 has spring pieces on both sides and a connecting piece connecting the bottom ends of the two spring pieces. The spring pieces have a first inclined portion extending obliquely from the connecting piece toward the base material cleaning brush 5 and abutting against the side of the base material cleaning brush 4, and a second inclined portion extending obliquely outward from the first inclined portion abutting against the side of the base material cleaning brush 5. The outer end of the second inclined portion of one spring piece abuts against the side of the outer frame front plate 132, and the outer end of the second inclined portion of the other spring piece abuts against the side of the locking plate. The base material cleaning brush 5 can be movably locked onto the outer frame front plate 132 by the locking plate and the U-shaped clamp 134, which facilitates the up and down adjustment of the position of the base material cleaning brush 5 and makes it easy to replace the base material cleaning brush 5.

[0047] The base material collection trough 4 of the present invention is provided with a baffle 6 on the side near the fabric cart frame 1 to prevent base material from falling into the fabric cart frame 1; the baffle 6 is locked to the front side plate 11 of the fabric cart frame 1 by a connecting plate 61, the lower part of the connecting plate 61 is provided with two rows of first locking holes 611, and the front side plate of the fabric cart frame 11 is provided with two rows of second locking holes 612 corresponding to the two rows of first locking holes 611. The connecting plate 61 is locked to the inner side of the front side plate 11 by locking the first locking holes 611 and the second locking holes 612 with a fifth bolt 613; the connecting plate 61 is locked to the inner side of the front side plate 11 by locking the first locking holes 611 and the second locking holes 612; the connecting plate 61 is locked to the inner side of the front side plate 11 by locking the fifth bolt 613 into the first locking holes 611 and the second locking holes 612; the connecting plate 61 is locked to the front side plate 11 by locking the fifth bolt 613 into the first locking holes 611 and the second locking holes 612.

The baffle 6 is provided with a row of vertical elongated adjustment holes 62 corresponding to the row of third locking holes 614. The sixth bolt 63 passes through the elongated adjustment holes 62 and is locked in the third locking holes 614 to lock the baffle 6 and the connecting plate 61 together. The structure of the sixth bolt 63, the elongated adjustment holes 62 and the third locking holes 614 can adjust the position of the baffle 6 up and down, which can better prevent the base material from falling into the material frame 1 of the fabric cart, avoid the base material and the fabric from mixing and causing the fabric surface to be unclean, and improve the molding quality of the double-layer brick.

[0048] The fabric cart frame 1 of the present invention is provided with a base material positioning scraper 7 at its front end. Both ends of the base material positioning scraper 7 are locked with linkage rods 71. The two linkage rods 71 ​​are respectively pivotally connected to both sides of the fabric cart frame 1 via pivot shafts 72. Furthermore, both ends of the base material positioning scraper 7 are respectively provided with a lifting cylinder 8 for pushing the base material positioning scraper 7 up and down. The lifting cylinder 8 has a piston seat 81 located in the middle, a first piston rod 82 located at the lower end of the piston seat 81, and a second piston rod 83 located at the upper end of the piston seat 81. The linkage rods 71 ​​are close to the base material positioning scraper 7. A base 73 is provided on the top surface of one end, and the first piston rod 82 is pivotally connected to the base 73. The second piston rod 83 is pivotally connected to a top stop 84. The top stop 84 has a first vertical rod 841 pivotally connected to the second piston rod 83, a second vertical rod 842 that is pivotally connected to the front side plate 11 of the material frame 1 of the material carrier, and a transverse portion 843 connecting the first vertical rod 841 and the second vertical rod 842. The length of the first vertical rod 841 is less than the length of the second vertical rod 842. When the existing material carrier advances to place material on the brick mold, it can... The base material positioning scraper 7 is driven by the lifting cylinder 8 to rotate around the pivot shaft 72 and descend until its bottom end is lower than the bottom end of the material frame 1 of the placing cart. During the forward movement of the placing cart, the base material positioning scraper 7 pushes the excess base material in the brick mold onto the base material placing cart on one side of the brick mold. This ensures that the height of the base material in the brick mold is uniform, resulting in the same height ratio between the base material layer and the surface layer of the produced double-layer brick, thus improving the production quality of the double-layer brick. Furthermore, when the placing cart retracts on the brick mold, the lifting cylinder 8 can pull the base material positioning scraper 7. The scraper 7 rotates around the pivot shaft 72 and rises until the bottom of the base material positioning scraper 7 is higher than the bottom of the fabric cart frame 1, thus preventing the base material positioning scraper 7 from scraping the fabric and preventing the base material on the base material positioning scraper 7 from mixing on the fabric surface, resulting in better brick making effect; moreover, the first piston rod 82 of the lifting cylinder 8 is pivotally connected to the base 73, and the second piston rod 83 of the lifting cylinder 8 is movably pulled against the front side plate 11 of the fabric cart frame 1 through the second vertical rod 842 of the top brake member 84, which can easily tilt the lifting cylinder 8 to the front end of the fabric cart frame 1.
