Description

Technical Field

[0001] The invention relates to the technical field of mine crushers, and in particular to a high-efficiency feeding mechanism for mine crushers. Background Art

[0002] The feeding mechanism of the impact crusher in the mining crusher is mostly composed of a feeding port and a feeding hopper, and the feeding is usually carried out by direct dumping. During the dumping process, some ore will fall off and eventually accumulate under the feeding port, requiring further shoveling and cleaning. At the same time, the ore cannot be evenly crushed after the rushing falling, resulting in uneven crushed materials, and the rushing falling will also cause ore accumulation, which will cause certain damage to the machine. In addition, the ore will splash during crushing, generating a large amount of noise pollution, and will cause damage to the machine body when used for a long time, and even residue will come out of the cavity, causing injuries to surrounding personnel. If the dumping volume is large, it will also cause blockage inside the machine body, thereby affecting the normal progress of the crushing work, and the raised dust will also cause pollution to the surrounding environment. Moreover, if the machine body is in a working state for a long time, it will also cause overheating of internal parts, which will further cause cracking and breakage of internal parts due to overheating. Therefore, the present application provides a high-efficiency feeding mechanism for a mining crusher to meet the needs. Summary of the invention

[0042] like Figures 3 to 6 , Fig.10As shown, the efficient feeding component includes a material blocking unit 4, an adjusting unit and a water spray assembly 48 which are connected to each other. The material blocking unit 4 is fixedly connected to the inner wall of the second material blocking plate 32, and the adjusting unit is connected to the second material blocking plate 32.

The second material blocking plate 43, the third material blocking plate 44 and the fourth material blocking plate 45 are all located in the feed port 2 , and its side walls are in contact with the inner wall of the feed port 2, the arc-shaped connecting plate 41 and the second baffle plate 43 are convexly arranged on one side wall close to the first sliding plate 332, and the other side walls are concavely arranged, and the arc-shaped connecting plate 41 is arranged to guide the ore in the first step, wherein the other side wall of the arc-shaped connecting plate 41 is provided with a weakening groove 46, and the weakening groove 46 is arranged to facilitate the deformation of the arc-shaped connecting plate 41, and further the distance between the first baffle plate 42, the second baffle plate 43, the third baffle plate 44, and the fourth baffle plate 45 can be adjusted, so that The size of the discharge port formed between the feed port 2 can be adjusted. The second baffle plate 43 is set to limit the amount of material discharge for the first time to prevent excessive entry of ore and the inability to crush it in time and evenly. The first baffle plate 42 is concave on one side wall close to the first sliding plate 332, and the other side wall is concave. The third baffle plate 44 is S-shaped. The first baffle plate 42 is set to facilitate the storage of a relative amount of ore between the first baffle plate 42 and the first sliding plate 332. The other side wall of the first baffle plate 42 is provided with a wave groove. In order to facilitate the installation of the support unit 5, the third baffle plate 44 is set to realize the bidirectional function of the first baffle plate 42 and the second baffle plate 43. The material leaked from the second baffle plate 43 can be collected and stored, and the flow of the collected material can be limited. The fourth baffle plate 45 is set in a straight plate shape. In order to facilitate the rapid unloading of ore, the distance between the side wall of the second baffle plate 43 close to the first sliding plate 332 and the inner side wall of the feed port 2 is greater than the distance between the side wall of the fourth baffle plate 45 close to the first sliding plate 332 and the inner side wall of the feed port 2.

[0044] The water spray assembly 48 includes a connecting pipe 481 fixedly connected to a side wall of the concave arrangement of the second baffle plate 43. The connecting pipe 481 is connected to an external water supply device through an external water pipe. This is a prior art and is not shown in the figure. A plurality of interconnected branch pipes 482 are connected to the connecting pipe 481. The arrangement of the branch pipes 482 can not only spray water on the inside of the crusher body 1 to reduce dust and cool down the machine, thereby avoiding dust from surging out, but also avoiding a series of problems such as cracking and damage caused by overheating of internal parts, and also plays a role in diversion. The other end of the branch pipe 482 passes through the third baffle plate 44 and is fixedly connected to the inner wall of the fourth baffle plate 45. The branch pipe 482 is fixedly connected to the inner wall of the second baffle plate 43 and fits the inner wall of the third baffle plate 44.

[0045] The adjusting unit includes a supporting unit 5 arranged above the connecting pipe 481. The supporting unit 5 is made of elastic material. The supporting unit 5 is provided to lift the weakened groove 46 to prevent it from bending by itself. A bolt 6 is provided on the supporting unit 5. The bolt 6 is screwed to the second blocking plate 32 through a threaded hole. In order to facilitate the operation of the bolt 6 to achieve the purpose of adjusting the blocking unit 4; the supporting unit 5 includes an arc-shaped abutment plate 51, a curved arc plate 52, a wave plate 53 and a positioning plate 54 that are fixedly connected in sequence. The arc-shaped abutment plate 51 is provided to facilitate fixing to prevent the curved arc plate 52 from bending. , the wave plate 53 and the retaining plate 54 fall off, the arc plate 52 is provided for easy bending to achieve the purpose of adjusting the angle, the arc abutment plate 51 is fixedly connected to the inner wall of the second blocking plate 32, and the arc abutment plate 51 is provided with a movable hole sleeved on the bolt 6 to avoid interference with the movement of the bolt 6, the arc plate 52 is fitted with the arc connecting plate 41, and the wave plate 53 is fixedly connected to the wave groove. In order to increase the stability of the wave plate 53, the retaining plate 54 is clamped on the connecting pipe 481 and fixed, and the retaining plate 54 is rotatably connected to the bolt 6 on one side wall away from the arc abutment plate 51.

[0046] By setting the efficient feeding components, during use, the material will first enter between the second sliding plate 333 and the arc connecting plate 41, and then enter between the first baffle plate 42 and the first sliding plate 332 for the first collection, and then enter between the second baffle plate 43 and the feeding port 2 for the first restriction of the amount of material discharged, while also allowing the dumped ore to be buffered for the first time. The next step is to enter between the concave position of the third baffle plate 44 and the feeding port 2 for the second collection, and further enter between the convex position of the third baffle plate 44 and the feeding port 2 for the second restriction of the amount of material discharged, and further allow the ore to be steadily discharged between the fourth baffle plate 45 and the feeding port 2. If it is necessary to adjust the size of the material discharged between the baffle unit 4 and the feeding port 2, the bolt 6 can be screwed, which will cause the bolt 6 to move outward or inward, and further cause the positioning plate 54 to pull the wave plate 53 to move, which will The curved plate 52 is deformed and the first baffle plate 42 is pulled at the same time. In the process, the weakened groove 46 is deformed, which in turn causes the arc connecting plate 41 to deform, and further causes the second baffle plate 43, the third baffle plate 44 and the fourth baffle plate 45 to move. After adjustment, stop screwing the bolt 6, so that the discharge port between the baffle unit 4 and the feed port 2 can be adjusted. If there is a lot of dust or internal parts are overheated, water can be supplied through an external water supply device. When water is injected through an external water pipe, the water will enter the branch pipe 482 through the connecting pipe 481, and further cooling or dust reduction can be performed. Compared with the existing feeding mechanism, the present invention not only realizes the speed control of the feeding through the above structure, avoids the inability to crush evenly after the swarming and falling of the materials, but also avoids the damage to the machine caused by accumulation. At the same time, it can also be adapted to ores of different sizes for use, and cooling and dust reduction can be performed simultaneously.

[0047] like Figures 6 to 9As shown, the buffer unit 7 includes a buffer sleeve 71 attached to the side walls of the third baffle plate 44 and the fourth baffle plate 45. The buffer sleeve 71 is provided so that ore can fall on it, avoiding the contact between the ore and the crusher body 1 to generate a large amount of noise pollution. The buffer sleeve 71 is located below the connecting pipe 481. A buffer elastic component 72 is provided in the cavity of the buffer sleeve 71. The buffer elastic component 72 is provided to provide a buffering force to the buffer sleeve 71. A side wall of the buffer sleeve 71 and the buffer elastic component 72 close to the third baffle plate 44 is provided with a plurality of hanging holes 73, and the hanging holes 73 are hung inside. An L-shaped hanging block 74 is provided which is fixedly connected to the third material baffle plate 44. To facilitate installation and replacement in case of later damage, the buffer elastic component 72 is concavely arranged in the middle section of the side wall away from the third material baffle plate 44, and its thickness away from the cavity is greater than the thickness of the other side wall away from the cavity, so as to avoid damage too quickly. The buffer elastic component 72 includes a curved U-plate 721 fixedly connected to the cavity of the buffer sleeve 71, and a combination of spring clips 722 is fixedly connected between the two ends of the curved U-plate 721. The combination of spring clips 722 is fixedly connected to the inner wall of the cavity of the buffer sleeve 71, and its inner wall is the inner wall of the side away from the third material baffle plate 44.

[0048] By setting the buffer unit 7, when in use, when the ore after separation splashes onto the buffer sleeve 71, the resilience of the buffer sleeve 71 itself will reduce the noise generated by the collision with the inner wall. At the same time, the buffer sleeve 71 can be collected in a centralized manner. If the impact force is large, the buffer sleeve 71 will push the combined spring pieces 722 to deform, further buffering the impact force. Compared with the existing feeding mechanism, the present invention can avoid ore splashing and reduce the noise caused by impacting the machine body through the above structure, further avoiding damage to the machine body, and further avoiding damage caused by ore fragments leaving the cavity.

[0049] Through the coordinated arrangement of the baffle unit 4 and the buffer unit 7, when the ore splashes onto the buffer sleeve 71 during use, the impact force will cause the buffer sleeve 71 and the buffer elastic component 72 to vibrate, and further cause the L-shaped hanging block 74 to vibrate, and further cause the fourth baffle plate 45 to vibrate. The vibration of the fourth baffle plate 45 will drive the third baffle plate 44, the second baffle plate 43, the first baffle plate 42 and the arc connecting plate 41 to vibrate, and then cause the second blocking plate 32, the pocket plate 33, and the third blocking plate 34 to vibrate, which will cause the internal ore to vibrate. Compared with the existing feeding mechanism, the present invention avoids the blockage of ore during feeding through the above structure, which further affects the progress of the work. At the same time, the baffle unit 4 and the buffer unit 7 also block the dust, thereby avoiding a large amount of dust from pouring out of the inlet from the bottom to cause surrounding annular pollution.

[0050] The working principle of the technical solution provided by the present invention is as follows: when the ore is poured into the feed hopper 3, the material will fall on the second slide plate 333, and slide along the first slide plate 332 and the arc chamfer 334 to the feed port 2. During transportation and dumping, the arc chamfer 334 is blocked.

[0051] During use, the material will first enter between the second sliding plate 333 and the arc-shaped connecting plate 41, and then enter between the first baffle plate 42 and the first sliding plate 332 for the first collection, and then enter between the second baffle plate 43 and the feed port 2 for the first restriction of the amount of material discharged, while also allowing the dumped ore to be buffered for the first time. The next step is to enter between the concave position of the third baffle plate 44 and the feed port 2 for the second collection, and further enter between the convex position of the third baffle plate 44 and the feed port 2 for the second restriction of the amount of material discharged, and further allow the ore to be steadily discharged between the fourth baffle plate 45 and the feed port 2. If the size of the material discharged between the baffle unit 4 and the feed port 2 needs to be adjusted, it can be done by tightening the bolt 6 , which will cause the bolt 6 to move outward or inward, and further cause the positioning plate 54 to pull the wave plate 53 to displace, which will cause the curved plate 52 to deform, and also pull the first baffle plate 42. In this process, the weakening groove 46 will be deformed, which will cause the arc connecting plate 41 to deform, and further cause the second baffle plate 43, the third baffle plate 44 and the fourth baffle plate 45 to move. After adjustment, stop tightening the bolt 6, so that the unloading port between the baffle unit 4 and the feed port 2 can be adjusted. If there is a lot of dust or the internal parts are overheated, water can be supplied through an external water supply device. When water is injected through the external water pipe, the water will enter the branch pipe 482 through the connecting pipe 481, and further cooling or dust reduction can be performed.

[0052] When the ore after separation splashes onto the buffer sleeve 71, the resilience of the buffer sleeve 71 itself will reduce the noise generated by the collision with the inner wall. At the same time, the buffer sleeve 71 can collect the noise in a centralized manner. If the impact force is large, the buffer sleeve 71 will push the combined spring pieces 722 to deform, further buffering the impact force. Compared with the existing feeding mechanism, the present invention can avoid ore splashing and reduce the noise caused by impacting the machine body through the above structure, further avoiding damage to the machine body, and further avoiding damage caused by ore fragments leaving the cavity.

[0053] Through the coordinated arrangement of the baffle unit 4 and the buffer unit 7, when the ore splashes onto the buffer sleeve 71 during use, the impact force will cause the buffer sleeve 71 and the buffer elastic component 72 to vibrate, and further cause the L-shaped hanging block 74 to vibrate, and further cause the fourth baffle plate 45 to vibrate. The vibration of the fourth baffle plate 45 will drive the third baffle plate 44, the second baffle plate 43, the first baffle plate 42 and the arc-shaped connecting plate 41 to vibrate, and then cause the second blocking plate 32, the pocket plate 33, and the third blocking plate 34 to vibrate, which will cause the internal ore to vibrate.

[0054] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
