Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost drawing crushing, in particular to an engineering cost drawing crushing mechanism. Background Art

[0002] Construction cost drawings are important reference materials for buildings or engineering projects before construction. They show the size, materials, structure and other information of the project in detail, which is crucial for cost calculation and budgeting. In the drawing of the construction cost of the engineering building, due to repeated modification and improvement of different data, discarded drawings will be generated. Usually, in order to prevent the leakage of building parameters, the discarded drawings will be crushed with a crusher to achieve confidentiality.

[0003] After searching, Chinese patent announcement number: CN220610555U discloses a construction cost drawing crushing mechanism, which includes setting a separation plate and a driving machine to drive two crushing rollers to rotate. The two crushing rollers cooperate with each other to crush the construction cost drawings into strip fragments. At this time, the strip fragments fall into the liquid tank and are immersed in water. The paper fibers break and gradually decompose after encountering water. At this time, the decomposed paper will pass through the separation plate and be deposited inside the liquid tank. The construction cost drawings that have decomposed in water can completely erase the parameters, thereby effectively avoiding the occurrence of construction cost drawing data leakage.

[0004] However, in actual use of the above-mentioned crushing mechanism, the paper fragments crushed by the crushing roller are light in weight and have a large surface area. When they fall into the liquid tank through the crushing roller, they will float on the water surface. After the water soaks the fragments, when the weight of the fragments is greater than the buoyancy of the water surface, the fragments will completely enter the water and be stirred to accelerate the decomposition efficiency. It takes a long time to wait for a large number of fragments to naturally sink into the water, which will affect the crushing efficiency of the drawings. Therefore, an engineering cost drawing crushing mechanism is proposed to solve the above problems. Utility Model Content

In the utility model, by cooperating with the provided chamfers, motors, rotating rods, conical blocks, scraping units, multi-section electric push rods and extrusion filter plates, the fragments that fall into the decomposition cylinder and float on the water surface can be squeezed downward, so that the fragments sink into the water quickly and come into full contact with the water, thereby accelerating the decomposition efficiency and avoiding the influence of the crushing efficiency due to the inability of the fragments to sink into the water quickly due to their lightness.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 2 The utility model provides an embodiment: a construction cost drawing crushing mechanism, comprising a crushing box 1, the upper sides of the left and right sides of the inner surface of the crushing box 1 are fixedly connected with guide plates 2, a crushing roller 3 is provided inside the crushing box 1, and a driver is provided at the rear end of the crushing roller 3. When the driver is started, the crushing roller 3 can be driven to rotate, thereby crushing the passing drawings. The drawings can slide along the inclined surface of the guide plate 2 to the crushing roller 3 for crushing. A decomposition cylinder 4 is fixedly connected to the bottom surface of the crushing box 1, and a liquid inlet pipe is fixedly connected to the rear side of the decomposition cylinder 4 (Figure 1). Not directly shown in the figure), the rear end of the liquid inlet pipe passes through the crushing box 1, and clean water can be added to the interior of the decomposition cylinder 4 through the liquid inlet pipe. After the drawings are broken into fragments, they can fall downward into the interior of the decomposition cylinder 4, and then the fragments can be decomposed by water. The bottom end of the decomposition cylinder 4 is fixedly connected to a drain pipe, and the outer side of the drain pipe is fixedly connected to a solenoid valve. When the solenoid valve is activated, the drain pipe can be opened to discharge the liquid mixed with paper fibers. The upper end of the interior of the decomposition cylinder 4 is provided with a chamfer 5. When the fragments fall above the decomposition cylinder 4, they can slide along the inclined surface of the decomposition cylinder 4 into the interior of the decomposition cylinder 4.

[0033] Reference Figure 3-Figure 5 The bottom surface of the crushing box 1 is fixedly connected with a motor 6, and the top output end of the motor 6 runs through the crushing box 1. The top output end of the motor 6 is fixedly connected with a rotating rod 7. When the motor 6 is started, the rotating rod 7 can be driven to rotate. The top of the rotating rod 7 is fixedly connected with a conical block 8. When the rotating rod 7 rotates, the conical block 8 can be driven to move synchronously. The conical block 8 is located directly above the inside of the decomposition cylinder 4 and directly below the crushing roller 3. The conical block 8 can block the top of the extrusion filter plate 10 arranged below to prevent fragments from falling above the extrusion filter plate 10 and being unable to fall into the water for rapid decomposition, affecting the crushing efficiency. When the fragments fall above the conical block 8, they can slide along the inclined surface of the conical block 8 to the chamfer 5, and finally slide into the decomposition cylinder 4 along the inclined surface of the chamfer 5.

[0034] A scraping unit is provided on the outside of the conical block 8. The scraping unit includes a connecting rod 81, which is fixedly connected to the bottom surface of the conical block 8. The bottom end of the connecting rod 81 is fixedly connected to a lower scraper 82. The bottom surface of the lower scraper 82 fits the surface of the chamfer 5. When the conical block 8 rotates, the connecting rod 81 can drive the lower scraper 82 to rotate synchronously, so that the lower scraper 82 can scrape the fragments falling onto the chamfer 5, so that the fragments can quickly slide down the inside of the decomposition cylinder 4 after falling onto the chamfer 5. The right inner wall surface of the crushing box 1 is fixedly connected to a fixing rod 83, and the left end of the fixing rod 83 is fixed. An upper scraper 84 is connected, and the bottom surface of the upper scraper 84 fits with the upper surface of the conical block 8. The upper scraper 84 is fixedly connected to the crushing box 1 through a fixing rod 83. When the conical block 8 rotates, the upper scraper 84 can move the fragments on the conical block 8 to accelerate the sliding of the fragments. The front and rear ends of the upper surfaces of the lower scraper 82 and the upper scraper 84 are both inclined. When fragments fall onto the lower scraper 82 and the upper scraper 84, they can slide along the inclined surface above the lower scraper 82 and the upper scraper 84 to avoid the fragments falling onto the lower scraper 82 and the upper scraper 84 and being difficult to fall, which affects the crushing and decomposition effect.

[0035] The bottom surface of the conical block 8 is fixedly connected to a multi-section electric push rod 9, and the bottom end of the multi-section electric push rod 9 is fixedly connected to an extrusion filter plate 10. The bottom diameter of the conical block 8 is larger than the extrusion filter plate 10. The extrusion filter plate 10 is plugged into the inside of the decomposition cylinder 4. When the multi-section electric push rod 9 is started, it can drive the extrusion filter plate 10 to perform linear motion in the up and down directions. When the extrusion filter plate 10 moves downward, it can be plugged into the decomposition cylinder 4 to squeeze the fragments floating on the water surface, so that the fragments sink into the water quickly, make comprehensive contact with the water, and accelerate the decomposition efficiency.

[0036] Reference Figure 3-Figure 4The interior of the decomposition cylinder 4 is fixedly connected with a fixed filter plate 11, which can block the debris falling into the water to prevent the larger debris that is not completely decomposed from settling directly downward, causing blockage of the drain pipe and affecting the discharge of water. The upper end of the rotating rod 7 passes through the fixed filter plate 11, and the outer wall of the fixed filter plate 11 fits with the inner wall of the decomposition cylinder 4. The outer surface of the rotating rod 7 is fixedly connected with a push plate 12, and the bottom surface of the push plate 12 fits with the upper surface of the fixed filter plate 11. When the rotating rod 7 rotates, the push plate 12 can rotate, and when the push plate 12 rotates, it can move with the broken paper scraps Friction occurs, thereby accelerating the decomposition speed of broken paper in water and preventing paper scraps from accumulating and clogging at the fixed filter plate 11. A cleaning plate 13 is fixedly connected to the lower side of the outer wall surface of the rotating rod 7. The outer wall of the cleaning plate 13 fits into the inner wall surface of the decomposition cylinder 4. When the rotating rod 7 rotates, the cleaning plate 13 can be driven to rotate synchronously. When the cleaning plate 13 rotates, the water flow below the fixed filter plate 11 can be stirred. When the drain pipe is opened, as the liquid level gradually drops, the rotation of the cleaning plate 13 can stir the water flow, so that the water flow can be better discharged from the drain pipe.

[0037] Working principle: Put the drawings into the crushing box 1 from above, so that the drawings slide along the inclined surface of the guide plate 2 to the crushing roller 3 for crushing. After the drawings are crushed, they will become fragments and fall downwards. When the fragments fall above the conical block 8, they can slide along the inclined surface of the conical block 8 to the chamfer 5, and slide along the inclined surface of the chamfer 5 into the water flow inside the decomposition cylinder 4 for decomposition. At this time, the motor 6 is started to drive the conical block 8, the push plate 12 and the cleaning plate 13 to rotate synchronously through the rotating rod 7. When the conical block 8 rotates, the scraper 82 is driven to rotate through the connecting rod 81 to move the fragments that fall on the chamfer 5, thereby accelerating the decomposition. The debris on the corner 5 falls, and the upper scraper 84 will move the debris on the conical block 8, thereby accelerating the falling of the debris on the conical block 8. When the debris completely enters the decomposition cylinder 4, the multi-section electric push rod 9 can be started to drive the extrusion filter plate 10 to move downward, and the debris floating on the water surface inside the decomposition cylinder 4 can be squeezed downward, so that the debris can be completely immersed in the water, and the water has comprehensive contact, which accelerates the decomposition efficiency. When the push plate 12 rotates, it can rub against the broken paper scraps, thereby speeding up the decomposition speed of the broken paper scraps in the water. Finally, after the fragments are decomposed, they can be discharged through the drain pipe, and the parameters on the drawing can be completely erased and cannot be restored.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
