Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to a crushing chamber structure for a sand making machine. Background Technology

[0002] The crushing chamber structure of a sand making machine is the core spatial structure that enables the crushing function of sand making equipment. In the sand making process, this structure undertakes the key function of material crushing. Its geometric parameters directly determine the crushing path and stress state of the material. It is a core element affecting sand making efficiency, energy consumption and finished particle shape. It is mainly used in the production of sand and gravel aggregates in the mining, construction and building materials industries.

[0003] A search revealed Chinese patent publication number CN213726968U, which discloses a crushing chamber for a sand making machine. The chamber includes a circular disc with a closed-loop boss protruding from its inner bottom surface. Several partition plates are arranged within the disc. Two adjacent partition plates form a horn-shaped chamber. An mounting plate stands upright outside the horn-shaped chamber. A first distance exists between the mounting plate and another mounting plate forming the horn-shaped chamber, with the side edge of the mounting plate fixed to its sidewall. An anvil is flatly attached to the mounting plate, and a second distance exists between the anvil and the aforementioned closed-loop boss. The anvil and the aforementioned mounting plate are connected by a plug-in structure. The mounting plate is detachably installed on the side facing the side wall, which restricts the upward movement of the anvil. Compared with the existing technology, each of its bell-shaped chambers can obtain stone-on-stone crushed material and stone-on-iron crushed material, so that the central discharge port receives a mixture of materials. The material shape effect is neutral, the output is good, and the defects of traditional single stone-on-stone crushers and stone-on-iron crushers are eliminated. However, the existing crushing chamber has too many positioning plates, resulting in low utilization of the crushing chamber space and insufficient material impact, which affects the crushing efficiency and sand quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a crushing chamber structure for a sand making machine, including a crushing chamber 1, which provides space for material crushing. A crushing mechanism 2 is arranged inside the crushing chamber 1, which crushes the material by impact crushing it. A discharge mechanism 3 is arranged at the bottom of the crushing mechanism 2, which quickly discharges the material. The crushing mechanism 2 includes an annular liner 201, the outer walls of which are fixedly connected to the inner side of the crushing chamber 1, forming an annular crushing space and protecting the sidewalls of the chamber. Multiple positioning plates 202 are fixedly connected to the inner side of the crushing chamber 1 to guide the crushing trajectory of the material. A fixing plate 203 is fixedly connected to the left side of each positioning plate 202 to secure the positioning plates 202. Multiple conical shaping plates 204 are fixedly connected to the inner side of the annular liner 201 to shape the crushed material and improve the finished particle shape. A protective block 205 is fixedly connected to the top inner side of the crushing chamber 1 to prevent material rebound. A feeding assembly 206 is provided on the top of the protective block 205 to guide the material to enter the crushing chamber evenly. The crushing chamber and feeding assembly 206 include a feeding bracket 2061. The bottom of the feeding bracket 2061 is fixedly connected to the top of the crushing chamber 1. The feeding bracket 2061 supports the feeding hopper 2062. The feeding hopper 2062 is fixedly connected to the bottom inner side of the feeding bracket 2061. The feeding hopper 2062 receives and conveys materials into the crushing chamber. A fixing assembly 207 is provided in the middle of the inner side of the crushing chamber 1, which can fix the throwing assembly 208. The throwing assembly 208 is provided on the top of the fixing assembly 207, which can throw and crush materials through high-speed rotation. The material throwing assembly 208 includes a motor 2081. The top of the motor 2081 is fixedly connected to the bottom of the mounting base 2072, which can provide rotational power for the material throwing disc 2083 and drive the crushing operation. The bottom of the mounting base 2072 is fixedly connected to the outer shell 2082, which can protect the motor 2081. The top of the mounting base 2072 is rotatably connected to the material throwing disc 2083, which rotates at high speed under the drive of the motor 2081 and throws the material toward the crushing mechanism 2. The top of the material throwing disc 2083 is fixedly connected to multiple wear-resistant plates 2084, which guide the material to be thrown evenly toward the crushing mechanism 2.

[0040] Specifically, the material enters the crushing chamber 1 through the feeding assembly 206. The feeding bracket 2061 supports the feeding hopper 2062, which conveys the material into the crushing chamber. The motor 2081 of the throwing assembly 208 drives the throwing disc 2083 to rotate at high speed. The wear-resistant plate 2084 on the top of the throwing disc 2083 guides the material to be evenly thrown towards the crushing mechanism 2. The annular liner 201 of the crushing mechanism 2 is fixed inside the crushing chamber 1 to form an annular crushing space. The positioning plate 202 on its inner side positions and guides the material crushing trajectory. The fixing plate 203 fixes the positioning plate 202. The conical shaping plate 204 shapes the crushed material to improve its shape. To improve the particle shape, the protective block 205 is fixed to the top of the inner side of the crushing chamber 1 to prevent material rebound. After being crushed by impact in the crushing mechanism 2, the material falls from the crushing chamber 1 into the discharge chamber 301. The discharge chamber 301 guides the material to the truncated cone-shaped discharge port 302. The guide rib 303 on the inner side of the discharge chamber 301 guides the material to converge towards the center to accelerate the discharge speed. Compressed air in the gas cylinder 3043 is transported to the annular air chamber 3041 through the air pipe 3042. The air hole at the bottom of the annular air chamber 3041 sprays to form an annular air curtain to suppress dust when the material is discharged. The installation component 305 fixes the dust suppression component 304 on the sand making machine to ensure structural stability.

[0041] Reference Figure 2 , Figure 3 and Figure 5 The discharge mechanism 3 includes a discharge chamber 301, the top of which is fixedly connected to the bottom of the crushing chamber 1. The discharge chamber 301 collects and conveys the crushed material to the discharge port 302. The discharge port 302 is fixedly connected to the bottom of the discharge chamber 301. The discharge port 302 is frustum-shaped to increase the material discharge area. Multiple guide ribs 303 are fixedly connected to the inner side of the discharge chamber 301 to guide the material to converge towards the center, accelerate the discharge speed, and prevent accumulation. A dust suppression component 304 is provided at the bottom of the discharge port 302 to suppress the dust generated when the material is discharged. The dust suppression component 304 includes... The annular air chamber 3041 is fixedly connected to the bottom of the discharge port 302 at its top. The bottom of the annular air chamber 3041 has multiple air holes to form an annular air curtain. The left side of the annular air chamber 3041 is connected to an air pipe 3042, which can deliver compressed air from the air cylinder 3043 to the annular air chamber 3041. The other end of the air pipe 3042 is connected to the air cylinder 3043, which can store compressed air and provide a power source for the dust suppression air curtain. The bottom of the dust suppression component 304 is provided with an installation component 305, which can fix the dust suppression component 304 on the sand making machine to ensure structural stability.

[0042] Specifically, the crushed material falls from the crushing chamber 1 into the discharge chamber 301. The discharge chamber 301 concentrates the material and conveys it to the discharge port 302 at the bottom. The truncated cone-shaped discharge port 302 increases the material discharge area. The guide ribs 303 guide the material to converge towards the center to speed up the discharge speed and avoid accumulation. When the material is discharged through the discharge port 302, the gas cylinder 3043 delivers compressed air to the annular air chamber 3041 through the air pipe 3042. The air holes at the bottom of the annular air chamber 3041 form an annular air curtain to suppress dust.

[0043] Reference Figure 3 , Figure 4 and Figure 5 The fixing component 207 includes two reinforcing ribs 2071, the bottoms of which are fixedly connected to the left and right ends of the bottom inner side of the discharge chamber 301, respectively. This enhances the connection strength between the fixing component 207 and the discharge chamber 301 and improves the overall structural stability. A mounting base 2072 is fixedly connected between adjacent reinforcing ribs 2071 for mounting the material throwing component 208. The mounting component 305 includes a flange 3051, the top of which is fixedly connected to the gas cylinder 3043. At the bottom, the gas cylinder 3043 can be connected to the sand making equipment. The flange 3051 has four mounting holes 3052 at the top corners. The flange 3051 can be fixed to the sand making equipment by bolts passing through the mounting holes 3052. The two positioning plates 202 are each provided with a conical shaping plate 204 on an adjacent side. The top of the two positioning plates 202 is fixedly connected to the same protective block 205, which can form a small crushing space between the two positioning plates 202 to squeeze and shape the material to improve the particle shape.

[0044] Specifically, the two reinforcing ribs 2071 cooperate with the mounting base 2072 to provide an installation foundation for the throwing assembly 208, ensuring that the throwing disc 2083 remains stable when rotating. The flange 3051 of the mounting assembly 305 is connected to the top and the dust suppression assembly 304. It is connected to the sand making equipment with bolts through the mounting holes 3052 at the four corners to achieve a stable assembly of the gas cylinder 3043. The positioning plate 202 and the conical shaping plate 204 form a small crushing space, which improves the particle shape of the material and enhances the quality of the finished product through extrusion shaping.

[0045] Working principle: The material is received by the feed hopper 2062 of the feeding assembly 206, supported by the feeding bracket 2061 and conveyed into the crushing chamber 1. It falls onto the throwing disc 2083 of the throwing assembly 208. The motor 2081 drives the throwing disc 2083 to rotate at high speed through the mounting base 2072. The wear-resistant plate 2084 on the top of the throwing disc 2083 throws the material evenly towards the crushing mechanism 2. The material hits the positioning plate 202 and the conical shaping plate 204 on the inner side of the annular liner 201. The positioning plate 202 guides the crushing trajectory, and the conical shaping plate 204 impacts, crushes and shapes the material. The fixing plate 203 ensures the stability of the positioning plate 202, and the protective block 205 prevents the material from rebounding. The positioning plate 202 and the conical shaping plate 204 form multiple small crushing chambers to crush the material multiple times. The crushed material falls and is discharged. The annular space formed by the annular liner 201 protects the side wall of the chamber, realizing efficient crushing and shaping of the material.

[0046] Furthermore, the crushed material falls from the crushing chamber 1 into the discharge chamber 301. The discharge chamber 301 concentrates the material and guides it to the discharge port 302. The frustum shape of the discharge port 302 increases the material discharge area, allowing the material to be discharged more smoothly. The guide ribs 303 on the inner side of the discharge chamber 301 guide the material to converge towards the center, accelerating the discharge speed and preventing accumulation. When the material is discharged through the discharge port 302, the compressed air in the gas cylinder 3043 is transported to the annular air chamber 3041 through the air pipe 3042. Multiple air holes at the bottom of the annular air chamber 3041 spray compressed air to form an annular air curtain, effectively suppressing the dust generated when the material is discharged and improving the working environment.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
