Description

Technical Field

[0001] The invention relates to the technical field of garbage crushing, in particular to a construction waste crushing device for building construction. Background Art

[0002] When construction is being carried out at a construction site, workers need to crush and clean up the garbage generated by the construction. At this time, a construction waste crushing device is needed. The garbage crushing devices currently used in construction sites on the market are usually composed of crushing teeth and a storage cavity. In actual use, the construction waste is put into the storage cavity, and then the construction waste contacts the crushing teeth inside the storage cavity, which can realize the crushing teeth to quickly crush the construction waste inside the storage cavity. However, in actual use, there are still some shortcomings, such as:

[0003] 1. When construction waste is crushed inside the crushing device, a lot of powder will be generated inside the storage cavity. These powders will be discharged through the feeding end and the discharging end of the storage cavity. The powder discharged from the storage cavity will be scattered in the air, which is easy to pollute the environment of the construction site;

[0004] 2. The construction waste crushing devices on the market are not equipped with a good dust removal structure. When the crushing teeth of the construction waste crushing device crush the construction waste, the dust from the crushed construction waste is easy to accumulate around the crushing teeth. At this time, the dust from the crushed construction waste is easy to contact the bearings on the crushing teeth, which can easily cause wear of the bearings on the crushing teeth.

[0005] For this reason, we propose a construction waste crushing device for construction. Summary of the invention

[0006] A technical problem to be solved by the present application is that the powder discharged by the construction waste crushing device will be scattered in the air and the dust will easily contact the bearings on the crushing teeth.

[0007] In order to solve the above technical problems, the embodiment of the present application provides a construction waste crushing device for construction, including a crushing structure, and also including:

[0008] An air outlet funnel, wherein one end of the air outlet funnel away from the crushing structure is fixedly connected to a dust collecting hopper, and the dust collecting hopper can collect dust generated when the crushing structure crushes construction waste, and a filter screen is arranged inside the dust collecting hopper, and the filter screen can filter the dust inside the dust collecting hopper;

[0009] An air guide nozzle, which is distributed on the crushing structure, and the air blown out by the air guide nozzle can drive the dust inside the crushing structure to be transported to the inside of the air outlet funnel;

[0010] The crushing structure is rotatably connected to a transmission wheel, the transmission wheel is fixedly connected to a transmission rod, the transmission rod is sleeved with a bearing ring, the bearing ring is sleeved with a bearing shell, a protective ring is rotatably connected between the bearing shell and the bearing ring, a side of the protective ring facing away from the transmission wheel is fixedly connected with transmission blades at equal intervals, an end of the transmission blade close to the bearing ring is provided with a guide portion, and a portion of the bearing ring close to the guide portion is provided with an inclined portion.

[0011] In some embodiments, the outer wall of the bearing shell is fixedly connected to the crushing structure, a ball is embedded between the bearing shell and the bearing ring near the transmission wheel, a sealing ring is rotatably connected between the bearing shell and the bearing ring on the side away from the protective ring, and the transmission wheel is connected to the transmission structure of the crushing structure.

[0012] In some embodiments, the crushing structure is detachably connected to an air pump structure, the air outlet end of the air pump structure is fixedly connected to an air guide tube, the air guide tube is connected to the air guide nozzle, and the air pump structure can transport external air to the interior of the air guide nozzle through the air guide tube.

[0013] In some embodiments, an air inlet hole is provided on the dust hopper, a water spray pipe is fixedly connected to the dust hopper, an inner cavity of the dust hopper is connected with an inner cavity of the air outlet funnel through the air inlet hole, and a transmission column runs through the dust hopper.

[0014] In some embodiments, embedded frames are fixedly connected to the transmission column at equal intervals, and a filter is fixedly connected to the embedded frame. The embedded frame can scrape the inner wall of the dust hopper.

[0015] In some embodiments, both ends of the transmission column are fixedly connected with fixed blocks, the filter screen is a rectangular sheet structure, and the embedded frame can drive the dust on the inner wall of the dust collecting hopper to be transported to the filter screen.

[0016] In some embodiments, an air intake pipe and an oil supply pipe are fixedly connected to the bearing shell, and the air intake pipe and the oil supply pipe are distributed between the transmission wheel and the crushing structure, and the air outlet end of the air intake pipe is opposite to the transmission blade.

[0017] In some embodiments, a second ear block and a first ear block are distributed in the lower part of the dust hopper, the first ear block is distributed below the second ear block, the second ear block and the first ear block are fixedly connected with fixing bolts, and the second ear block and the first ear block are fixedly connected to the dust hopper through the fixing bolts.

[0018] In some embodiments, an insert rod passes through the second ear block and the first ear block, one end of the insert rod is fixedly connected to a protective block, the other end of the insert rod is fixedly connected to an abutment ball, and a connecting spring is sleeved on the insert rod between the abutment ball and the second ear block.

[0020] The present invention has at least the following beneficial effects:

[0021] 1. When the crushing structure crushes the construction waste, the dust generated by the crushing will come into contact with the air sprayed from the air guide nozzle. At this time, the air sprayed from the air guide nozzle will drive the dust into the interior of the air outlet funnel, which can prevent more dust from overflowing through the discharge end and feed end of the crushing structure.

[0022] 2. When the exhaust funnel in the crushing structure collects dust during the crushing of construction waste, the transmission column can drive the filter to collect the dust through the embedded frame, and then the water pipe drives the external water to spray water on the dust on the filter, which can prevent the dust from floating when the filter drives the dust to move.

[0023] 3. When the embedded frame in the crushing structure drives the filter to filter the dust of the construction waste, the abutment ball can drive the filter to vibrate through the embedded frame, and the dust on the filter can quickly fall onto the external dust collection structure.

When the air intake pipe in the crushing structure drives external air to blow the transmission blades, the transmission blades can drive the guide part to scrape the dust on the inclined part, which can avoid the dust from being concentrated between the bearing shell and the bearing ring. At the same time, the transmission blades can also drive the airflow between the bearing shell and the bearing ring to enhance, which can avoid the dust from being concentrated between the bearing shell and the bearing ring.

[0037] Example 1: Please refer to Figure 1 , 2 , 5-8, the present invention provides a technical solution:

[0038] A construction waste crushing device for construction, comprising a crushing structure 1, and further comprising:

[0039] An air outlet funnel 3, one end of the air outlet funnel 3 away from the crushing structure 1 is fixedly connected with a dust collecting hopper 4, the dust collecting hopper 4 can collect dust generated when the crushing structure 1 crushes the construction waste, and a filter screen 5 is arranged inside the dust collecting hopper 4, the filter screen 5 can filter the dust inside the dust collecting hopper 4;

[0040] The air guide nozzle 8 is distributed on the crushing structure 1. The air blown by the air guide nozzle 8 can drive the dust inside the crushing structure 1 to be transported to the inside of the air outlet funnel 3. The air guide nozzle 8 is distributed at the feeding end and the discharge end of the crushing structure 1, so that an air flow channel can be formed inside the crushing structure 1, and the dust generated when the crushing structure 1 crushes the construction waste can be prevented from being discharged through the feeding end and the discharge end of the crushing structure 1.

[0041] When the crushing structure 1 in the construction waste crushing device crushes the construction waste, the powder generated by the crushing of the construction waste will float inside the crushing structure 1. At this time, the air sprayed from the air nozzle 8 can form an air flow channel inside the crushing structure 1. The air sprayed from the air nozzle 8 can drive the powder generated by the crushing of the construction waste to enter the interior of the air outlet funnel 3. At the same time, the air outlet funnel 3 can drive the powder to be transported to the interior of the dust collecting hopper 4.

[0045] When the transmission paddle 25 drives the guide part 210 to rotate, the transmission paddle 25 can scrape the dust on the inclined part 211 through the guide part 210. At the same time, the transmission paddle 25 can drive the air to move at high speed between the bearing shell 24 and the bearing ring 27, so as to realize the dust discharge between the bearing shell 24 and the bearing ring 27, and avoid the dust inside the crushing structure 1 from contacting with the ball 29.

[0056] The abutting ball 94 is a spherical structure, and the outer wall of the abutting ball 94 can abut against the embedded frame 52. When the embedded frame 52 abuts against the abutting ball 94, the connecting spring 95 can be squeezed by the abutting ball 94.

[0057] When the filter 5 in the construction waste crushing device drives the transmission column 53 to rotate, the edge of the embedded frame 52 can push the abutment ball 94.
