[0002] In urban construction, the generation of construction waste is inevitable. When dealing with construction waste, it is necessary to crush the larger construction waste several times before recycling it. Common crushers include jaw crushers and cone crushers. The jaw crusher consists of two jaw plates, a moving jaw and a static jaw, to form a crushing chamber. It simulates the movement of the two jaws of an animal to complete the material crushing operation. It is mainly used as a coarse crusher and a medium crusher.
[0003] When the jaw crusher is working, construction waste enters the equipment from the top entrance, and is discharged from the bottom exit after being crushed. However, when using the jaw crusher, the construction waste at the entrance and exit needs to be transported by conveyor belts. During the transportation process, the dust generated by the collision of large pieces of construction waste is mostly at the bottom close to the conveyor belt. If it is not captured and absorbed in time, it is easy to diffuse into the air and pollute the working environment. A large amount of dust falls under the conveyor belt and accumulates, which will affect the normal operation of the equipment. In particular, the conveyor belt at the exit position has a small space above it, and ordinary dust collection equipment is difficult to install. Therefore, it is necessary to develop a special collection device for collecting dust at the bottom of the construction waste close to the conveyor belt during the transportation of the jaw crusher.

Therefore, they cannot be understood as limitations on the present invention.
[0024] Please refer to Figure 1-Figure 3A bottom dust side capture device for a jaw crusher, the jaw crusher comprises a conveyor belt 100, a top cover 200 is arranged above the conveyor belt 100, the dust side capture device comprises a side suction cover 1, a suction pipe 2, a side sealing curtain 3, and a front sealing curtain 4; the number of the side suction covers 1 is two and they are symmetrically arranged on both sides of the conveyor belt 100, the side suction cover 1 comprises a capture port 101 and a suction port 102, the capture port 101 is a slender flat port, and the extension direction of the capture port 101 is parallel to the conveying direction of the conveyor belt 100 The collecting port 101 is arranged toward the conveyor belt 100 and sucks the dust obliquely downward, the suction pipe 2 is connected with the suction port 102, the side sealing curtain 3 is installed on the side suction hood 1, the side sealing curtain 3 is located outside the collecting port 101 and the conveyor belt 100, and the bottom end freely hangs to the edge of the conveyor belt 100, the front sealing curtain 4 is installed on the top cover 200, and the bottom end freely hangs to the conveyor belt 100; the side suction hood 1, the top cover 200, the conveyor belt 100, the side sealing curtain 3 and the front sealing curtain 4 together form a closed dust collecting space.
[0025] The top cover 200 may be a dust collecting device installed above the conveyor belt 100, such as Figure 1 As shown, it can be used in conjunction with the top dust collection device to obtain a better dust collection effect; it can also be other equipment structures located above the conveyor belt 100, such as Figure 2 As shown, it can be installed in a limited small space and achieve dust capture.
[0026] When using the bottom dust side capture device protected by the utility model, when the construction waste is transported on the conveyor belt 100 of the jaw crusher, it first passes through the front sealing curtain 4, which can be a deformable sealing curtain such as a rubber curtain. The construction waste pushes the front sealing curtain 4 and enters the closed dust capture space. During the dynamic process of transportation, since the bottom end of the front sealing curtain 4 can fall freely, it falls on the moving construction waste to form a relatively sealed environment. The suction pipe 2 can be connected to a fan or other negative pressure device to provide a negative pressure airflow for the side suction hood 1, so that the dust on the conveyor belt 100 can be sucked by the negative pressure airflow and enter the side suction hood 1 from the capture port 101, thereby realizing the dust capture on the conveyor belt 100.
[0027] The dust side capture device of the utility model has the following advantages: firstly, the side suction hood 1 suctions at the side, and the collecting port 101 is arranged obliquely downward, so that the dust near the bottom of the conveyor belt 100, especially the dust pressed between the construction waste, can be easily sucked and captured from the side. Compared with sucking from the top, it occupies less space and has higher dust capturing efficiency at the bottom. After the dust at the bottom is sucked and captured, it can also greatly reduce the dust dispersion caused by the collision of construction waste during transportation. Secondly, the collecting port 101 of the side suction hood 1 is arranged as an elongated flat mouth. Compared with other shapes, the elongated flat mouth has stronger suction capacity and lower energy consumption.
[0028] In one embodiment, a side sealing plate 5 is further included, the top end of which is mounted on the side of the top cover 200 and the bottom end is mounted on the top of the side suction cover 1, and the side suction cover 1 and the top cover 200 are tightly connected via the side sealing plate 5. If the top of the side suction cover 1 cannot be tightly connected with the top cover 200 after installation, the sealing effect of the side dust capture space will be affected, so the side sealing plate 5 is used to ensure the sealing effect of the side, effectively preventing dust from escaping from the gap and polluting the working environment.
[0029] In one embodiment, the side suction hood 1 includes a collecting chamber 11 and a buffer chamber 12, the head end of the collecting chamber 11 is a collecting port 101, the tail end of the collecting chamber 11 is connected to the head end of the buffer chamber 12, and the tail end of the buffer chamber 12 is provided with a suction port 102 and connected to the suction pipe 2; the dust is captured by the collecting port 101, passes through the buffer chamber 12, and is then sucked and collected along the suction pipe 2.
[0030] Furthermore, the collection chamber 11 includes a bottom inclined plate 111, a top inclined plate 112 and a transition plate 113. The bottom inclined plate 111 is connected to the bottom of the head end of the buffer chamber 12 and is arranged obliquely downward. The transition plate 113 is connected to the top of the head end of the buffer chamber 12. The top inclined plate 112 is connected to the transition plate 113 and is arranged obliquely downward. The bottom inclined plate 111 and the top inclined plate 112 form a collection port 101 obliquely downward, which has a simple structure, low cost, and a better dust collection effect.
[0031] Furthermore, the inclination angle α of the top inclined plate 112 relative to the horizontal plane is greater than the inclination angle β of the bottom inclined plate 111 relative to the horizontal plane, ensuring that the collection port 101 is a slender flat port, the width of which is smaller than the width of the internal space of the collection hood, so that the negative pressure airflow suction force formed is strong and the energy consumption is lower.
[0032] In a preferred embodiment, the side sealing curtain 3 is fixed on the bottom inclined plate 111, which can ensure that the side sealing curtain 3 is located outside the collecting port 101 to avoid affecting the negative pressure suction airflow of the collecting port 101. At the same time, the cost is lower, which is conducive to mass production. The structure is simple and the installation is convenient, and it is suitable for various types of jaw crushers.
[0033] In one embodiment, the cache chamber 12 is in the shape of a funnel with a narrow head end and a wide tail end, and the width of the collection port 101 is smaller than the width of the head end of the cache chamber 12; this structure allows the negative pressure airflow to be pressurized layer by layer, pressurized once between the cache chamber 12 and the collection chamber 11, and pressurized again at the collection port 101, and by using simple structural improvements, stronger suction capacity and lower energy consumption are obtained.
[0034] In one embodiment, the side suction cover 1 is an integrated structure, which has a stronger sealing performance and negative pressure suction effect.
[0035] In one embodiment, the front sealing curtain 4 includes a plurality of curtain pieces, the top ends of which are integrally connected and fixed to the top cover 200, and the bottom ends of which freely hang down to the conveyor belt 100. The sealing curtain is composed of a plurality of curtain pieces, so it is easy to be pushed open by stones. When the construction waste is transported, the curtain pieces of the sealing curtain will hang down and close under the action of gravity, so that the inside of the collection hood returns to a sealed state, so that the area covered by the collection hood achieves a good sealing effect as a whole, effectively captures dust and prevents dust from escaping.
[0036] Preferably, the side sealing curtain 3 is an integrated plate structure made of rubber material, which has a certain deformation ability, can adapt to the collision of large pieces of construction waste while ensuring that it will not be damaged, and at the same time ensures a good sealing effect.
[0037] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
