Description

Technical Field

[0001] This utility model belongs to the field of casting sand removal technology, specifically a sand removal and crushing integrated machine. Background Technology

[0002] In traditional casting processes, after the casting is formed, it needs to be separated from the sand mold, which requires steps such as sand removal, crushing, screening and regeneration.

[0003] Shaking refers to the process of separating a casting from a sand mold. This can be achieved by manually tapping or mechanically vibrating the mold after it has cooled naturally. For example, in some foundries, vibratory shakeout machines are used to remove castings from sand molds while simultaneously separating the molding sand from the casting.

[0004] Crushing is the process of further refining the separated old or waste sand. Vibrating sand crushing machines are commonly used equipment; they use vibration to cause sand blocks to collide and break apart, thereby achieving regeneration.

[0005] The crushed sand needs to be screened to remove particles that do not meet the requirements. Screening ensures that the particle size of the recycled sand meets the casting requirements, and is usually done using a vibrating screen.

[0006] Recycling refers to the reuse of crushed and screened old sand in the casting process. Recycled sand can reduce the amount of new sand used, lower production costs, and contribute to environmental protection.

[0007] In traditional sand removal equipment, a sand box is placed on a sand removal grid plate. A vibration source provided by a vibrating motor breaks up the sand blocks inside the box, and the crushed sand enters the next stage through the outlet. After long-term use, the sand removal grid plate is prone to damage and deformation, requiring complete replacement. This not only increases maintenance time but also production costs and reduces operational efficiency. Furthermore, because the molding sand is only crushed once by the sand removal grid plate, it cannot be completely crushed. Additional crushing and screening equipment is needed for further crushing and screening, increasing equipment investment costs and the space occupied by the equipment. Utility Model Content

[0008] To address the issue of sand drop gratings being prone to damage and deformation, requiring complete replacement, which increases maintenance time, production costs, and reduces operational efficiency, this invention provides an integrated sand drop crushing machine.

[0009] This utility model is achieved through the following technical solution:

[0010] A sand crushing and pulverizing integrated machine includes a machine body and four support legs. Springs that provide elastic support to the machine body are connected and installed on the support legs. Inclined vibrating motors are installed on both side walls of the machine body. A feed inlet is provided at the front of the machine body, and a cross-arranged support grid frame is installed at the feed inlet position. A sand pulverizing grid plate is positioned and installed on the upper side of the support grid frame. The sand pulverizing grid plate includes several long strip-shaped sand pulverizing plates. A first grid rib plate, corresponding to the vertical ribs of the support grid frame and arranged along the entire length, is welded to one edge of the sand pulverizing plate. Several second grid rib plates, corresponding to the horizontal ribs of the support grid frame, are welded to the front and back of the sand pulverizing plate at intervals. The sand pulverizing plates are connected to the corresponding support grid frames by bolts. A crushing frame is installed at the rear bottom of the machine body. The crushing frame includes a crushing filter plate and several crushing rib plates welded to the upper side of the crushing filter plate. A waste gate is installed on the side of the machine body, and the waste gate corresponds to the upper edge of the crushing frame.

[0011] A further improvement of this utility model is that a temporary sand storage bin is provided on the lower side of the crushing frame, and a sand discharge regulating plate is provided at the outlet end of the temporary sand storage bin.

[0012] A further improvement of this utility model is that the bottom of the sand discharge regulating plate is provided with a number of sand discharge ports spaced apart along its length.

[0013] A further improvement of this utility model is that the sand discharge regulating plate has several vertically elongated regulating holes, and regulating bolts for connection and installation with the machine body are inserted into the regulating holes.

[0014] A further improvement of this utility model is that the rear side of the sand discharge regulating plate is provided with several reinforcing ribs that are perpendicular to the sand discharge regulating plate.

[0015] A further improvement of this utility model is that a sand discharge trough is provided at the rear of the sand discharge regulating plate, a filter screen is installed in the sand discharge trough, a fine sand chamber is formed at the bottom of the filter screen, and a fine sand outlet is provided at the rear end of the fine sand chamber; a coarse sand discharge pipe is connected to the rear of the sand discharge trough.

[0016] A further improvement of this utility model is that the filter screen has an arc-shaped structure with a convex center and downward curves on both sides.

[0017] A further improvement of this utility model is that a threaded rod is installed on the side of the machine body; one side of the waste door is rotatably connected to the machine body, and the other side has a notch that engages with the threaded rod; a rotating disc that can press the waste door is screwed onto the threaded rod.

[0018] A further improvement of this utility model is that the crushing frame is arranged at an upward inclination from front to back.

[0019] A further improvement of this utility model is that a vertically mounted crushing frame is also connected and installed at the rear edge of the inclined crushing frame.

[0020] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0021] During operation, casting sand is fed into the inlet, the vibrating motor runs, and the machine body is elastically supported by springs. This allows for effective crushing of the molding sand by the sand-falling grid plates (first and second grid ribs) (primary crushing). The crushed sand particles fall through the holes in the sand-falling plates to the bottom of the machine body. Vibration by the motor causes the particles at the bottom of the machine body to vibrate and be conveyed backward. The crushing ribs on the rear crushing frame further crush the primary crushed sand particles, and the secondary crushed sand particles are filtered and discharged through a crushing filter plate. Larger sand particles are periodically removed through the waste doors on the left and right sides of the machine body. This system achieves two-stage crushing and filtration of the casting sand, effectively reducing the particle size and enabling the recycling of the molding sand. Furthermore, the sand-falling grid plates are modularly designed, with multiple modules assembled and installed on the supporting grid frame. When individual modules are damaged after prolonged use, they can be replaced by disassembling the corresponding module, eliminating the need to disassemble and replace the entire sand-falling grid plate. This effectively improves maintenance efficiency, reduces maintenance costs, and increases operational efficiency. The overall structure is simple and compact, enabling secondary crushing and filtration of molding sand, effectively reducing the particle size of the molding sand, thereby reducing the need for additional crushing and screening equipment, lowering investment costs, and reducing equipment footprint.

[0032] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0033] like Figure 1-8As shown, this utility model discloses an integrated sand crushing machine, including a body 1 and four support legs 2. Springs 3 are connected and installed on the support legs 2 to provide elastic support to the body 1. Inclined vibrating motors 4 (eccentric) are installed at corresponding positions on the left and right side walls of the body 1, and the shafts of the vibrating motors 4 are inclined downwards at a 45-degree angle from front to back. A square feed inlet 11 is provided at the front of the body 1, and a support grid frame 17, constructed by cross-welding of I-beams, is installed at the feed inlet 11. The support grid frame 17 includes several I-beams in the front-to-back direction and several I-beams in the left-to-right direction. A sand crushing grid plate 5 is positioned and installed on the upper side of the support grid frame 17. The sand crushing grid plate 5 includes several sand crushing plate modules, each module comprising a front-to-back elongated (continuous) sand crushing... The sand plate 51 has a first grid reinforcement plate 52 welded along one side (left or right) of the sand drop plate 51, corresponding to the vertical ribs (H-beams in the front-back direction) of the supporting grid frame 17. The sand drop plate 51 has several second grid reinforcement plates 53 welded at intervals in the front and back, corresponding to the horizontal ribs of the supporting grid frame 17. The sand drop plate 51 is connected to the corresponding supporting grid frame 17 (the upper side of the H-beams is connected to bolts) by bolts. The crushing frame 6 is installed at the rear bottom of the machine body 1. The crushing frame 6 includes a crushing filter plate 61 and several crushing reinforcement plates 62 welded to the upper side of the crushing filter plate 61. The crushing reinforcement plates 62 are arranged in the front-back direction and are evenly spaced on the left and right sides. The waste gates 9 are installed on the left and right sides of the machine body 1, and the waste gates 9 correspond to the upper edge of the crushing frame 6.

[0034] In operation, casting sand is fed into the inlet 11, the vibrating motor 4 operates, and the machine body 1 is elastically supported by the spring 3. This allows for effective crushing (primary crushing) of the molding sand by the sand drop grid 5 (first grid rib 52 and second grid rib 53). The crushed sand particles fall through the holes on the sand drop plate 51 to the bottom of the machine body 1. Vibration by the vibrating motor 4 causes the particles at the bottom of the machine body 1 to vibrate and be conveyed backward. The crushing ribs 62 on the rear crushing frame 6 further crush the primary crushed sand particles, and the crushed sand particles are filtered and discharged through the crushing filter plate 61. Larger sand particles are periodically cleaned through the waste gates 9 on the left and right sides of the machine body 1. This process achieves two crushing and filtration of the casting sand, effectively reducing the particle size of the sand and enabling its recycling. Furthermore, the sand drop grid 5 is modularly designed, using multiple sand drop plate modules (such as...) Figure 4 The components are assembled and installed on the upper side of the support grid frame 17. When individual sand drop plate modules are damaged after long-term use, they can be replaced by disassembling the corresponding sand drop plate module, without the need to completely dismantle and replace the entire sand drop grid 5. This effectively improves maintenance efficiency, reduces maintenance costs, and increases operational efficiency. The overall structure is simple and compact, enabling secondary crushing and filtration of molding sand, effectively reducing the particle size of the molding sand, thereby reducing the need for additional crushing and screening equipment, lowering investment costs, and reducing equipment footprint.

[0035] Among them, such as Figure 4 As shown, the second grid rib plate 53 has pointed ends, and the first grid rib plate 52 has notches on both sides that cooperate with the pointed ends of the second grid rib plate 53, which can realize the precision and convenience of welding the sand drop plate module.

[0036] The machine body 1 has a threaded rod installed on its side in a left-right direction. The waste door 9 is rotatably connected to the machine body 1 on one side via a hinge, and has a notch on the other side that engages with the threaded rod. A rotating disc is screwed onto the threaded rod to press the waste door 9 into place. By connecting the rotating disc to the threaded rod and rotatably connecting the waste door 9 via the hinge, reliable locking of the waste door 9 can be achieved, preventing it from opening during vibration and enabling convenient opening of the waste door 9.

[0037] The crushing frame 6 is arranged at an upward inclination from front to back, and two crushing frames 6 are arranged at this inclination. This effectively reduces the backward vibration and conveying speed of the molding sand particles, enabling the crushing rib plate 62 to effectively crush the molding sand particles, and enabling the crushing filter plate 61 to effectively filter the crushed molding sand particles.

[0038] Furthermore, an upright crushing frame 6 is also connected and installed at the rear edge of the inclined crushing frame 6. The upright crushing frame 6 includes vertical crushing ribs 62 spaced apart on the left and right sides on the front side. This effectively crushes the molding sand vibrating to the rear through friction and collision, improving the crushing efficiency of the molding sand.

[0039] The inclined crushing frame 6 has a temporary sand storage bin 12 (connected to the machine body 1) on its lower side, and a sand discharge regulating plate 7 is provided at the outlet end of the temporary sand storage bin 12. The molding sand filtered and falling by the inclined crushing frame 6 is carried by the temporary sand storage bin 12 and conveyed backward by vibration motor 4. The material (molding sand particles) is discharged backward through the gap between the bottom of the sand discharge regulating plate 7 and the temporary sand storage bin 12.

[0040] The bottom of the temporary sand storage bin 12 is inclined upward from front to back to ensure that the output speed of the molding sand is not too fast during the process of the vibration motor 4 vibrating and conveying the molding sand particles backward.

[0041] Furthermore, the bottom surface of the temporary sand storage bin 12 is provided with several raised ribs in the left and right directions with front and back intervals, which effectively strengthens the structure of the temporary sand storage bin 12 and effectively prevents molding sand particles from rolling forward along the bottom surface of the temporary sand storage bin 12.

[0042] Furthermore, the bottom of the sand discharge regulating plate 7 is provided with several rectangular sand discharge ports 71 spaced apart along its length. Sand is discharged backward through the sand discharge ports 71.

[0043] Furthermore, the sand discharge regulating plate 7 has several vertically elongated regulating holes 72, and regulating bolts 73 connected to the machine body 1 are inserted into the regulating holes 72. By loosening the regulating bolts 73, the vertical position of the sand discharge regulating plate 7 can be flexibly adjusted, thereby realizing flexible adjustment of the amount of sand discharged through the bottom gap of the sand discharge regulating plate 7, which improves its applicability.

[0044] The sand discharge regulating plate 7 has several reinforcing ribs (arranged crosswise) perpendicular to it on its rear side. This effectively strengthens the structure of the sand discharge regulating plate 7, preventing deformation and twisting, and improving its service life and reliable sand discharge control.

[0045] The sand discharge regulating plate 7 has a sand discharge trough 13 at its rear, and a filter screen 8 is installed inside the sand discharge trough 13. The bottom of the filter screen 8 forms a divided fine sand chamber 16, and the rear end of the fine sand chamber 16 has a fine sand outlet 14. The rear of the sand discharge trough 13 is connected to a coarse sand discharge pipe 15. Molding sand particles conveyed from the bottom gap of the sand discharge regulating plate 7 enter the sand discharge trough 13, are filtered and screened again by the filter screen 8, and the fine sand enters the fine sand chamber 16 and is discharged through the fine sand outlet 14, improving the recycling quality of the molding sand. Molding sand particles that do not pass through the filter screen 8 are discharged through the coarse sand discharge pipe 15. In addition, the molding sand particles (a small amount) filtered by the vertically installed crushing frame 6 can fall directly into the sand discharge trough 13 for further filtration.

[0046] Furthermore, the filter screen 8 has an arc-shaped structure with a convex center and downward curves on both sides. While the filter screen 8 is filtering, the unfiltered molding sand particles are made to roll to both sides through vibration and are then conveyed backward through vibration to be discharged into the coarse sand discharge pipe 15 at the rear.

[0047] In this integrated sand crushing and dropping machine, casting sand is fed into the feed inlet 11, the vibrating motor 4 operates, and the machine body 1 is elastically supported by springs 3. This allows for effective crushing (primary crushing) of the molding sand by the sand dropping grid plates 5 (first grid ribs 52 and second grid ribs 53). The crushed sand particles fall through the holes in the sand dropping plate 51 to the bottom of the machine body 1. Vibration by the vibrating motor 4 causes the particles at the bottom of the machine body 1 to be conveyed backward. The crushing ribs 62 on the rear crushing frame 6 further crush the primary crushed sand particles, and the crushed sand particles are filtered and discharged through the crushing filter plate 61. Larger sand particles are periodically cleaned through the waste gates 9 on the left and right sides of the machine body 1. This system achieves two-stage crushing and filtration of the casting sand, effectively reducing the particle size and enabling the recycling of the molding sand. Furthermore, the sand dropping grid plates 5 are modularly designed, using multiple sand dropping plate modules (such as...) Figure 4The components are assembled and installed on the upper side of the support grid frame 17. When individual sand drop plate modules are damaged after long-term use, they can be replaced by disassembling the corresponding sand drop plate module, without the need to completely dismantle and replace the entire sand drop grid 5. This effectively improves maintenance efficiency, reduces maintenance costs, and increases operational efficiency. The overall structure is simple and compact, enabling secondary crushing and filtration of molding sand, effectively reducing the particle size of the molding sand, thereby reducing the need for additional crushing and screening equipment, lowering investment costs, and reducing equipment footprint.
