Description

Technical Field

[0001] This utility model relates to the field of sand making machine technology, specifically an environmentally friendly sand making machine for crushing sand and gravel. Background Technology

[0002] A sand making machine is an important piece of equipment used for crushing sand and gravel. It breaks raw materials into the desired particle size through different working principles and is widely used in construction, road construction, mining, and other fields. Its high efficiency and excellent particle shape make it an indispensable piece of equipment in sand and gravel production lines.

[0003] Existing sand making machines for crushing sand and gravel typically have motor-driven crushing rollers inside the machine casing to crush stones. However, during crushing, dust easily spreads outward from the feed inlet and discharge outlet, causing a large amount of dust to diffuse into the working environment, affecting the respiratory health of workers and normal operation. Therefore, we propose an environmentally friendly sand making machine for crushing sand and gravel. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly sand making machine for crushing sand and gravel, so as to solve the problem of dust spreading outward at the feed inlet and discharge outlet mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly sand making machine for crushing sand and gravel, comprising a casing, a feed inlet at the top of the casing, a discharge outlet on the side wall of the casing, a drive wheel on the side wall of the casing, a drive motor fixedly connected to the bottom of the casing, a transmission belt between the drive wheel and the drive motor, a crushing roller at the power output end of the drive wheel, a mating roller on the side wall of the crushing roller, a fixed connector on the side wall of the feed inlet, a sliding member and a sliding member slidably fitted inside the fixed connector, a rotating member rotatably connected inside the sliding member, multiple nozzles at the top of the rotating member, a joint on the side wall of the rotating member, and rotating shafts fixedly connected to both ends of the rotating member.

[0006] Preferably, a vent plate is rotatably connected to the side wall of the feed inlet, and a fixed frame is fixedly connected to the bottom of the vent plate.

[0007] Preferably, an axial flow fan is provided inside the fixed frame, and the axial flow fan is fitted to the bottom of the ventilated plate.

[0008] Preferably, a support plate is fixedly connected to the top of the ventilated plate, and a snap-fit ​​strip is fixedly connected to the side wall of the support plate.

[0009] Preferably, a fixing strip is fixedly connected to the side wall of the feed inlet, and a sliding clip is slidably fitted to the side wall of the fixing strip.

[0010] Preferably, the outer side of the mating roller is fitted with an arc-shaped shell fixed to the machine housing, and the bottom of the machine housing is provided with support legs.

[0011] Preferably, the top of the crushing roller is fitted with an inclined plate fixed to the machine housing, and the outside of the crushing roller is provided with multiple protrusions.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model has two sliding parts, one and two, which are fitted to the fixed part on the side wall of the feed inlet. The sliding parts can be pulled out to both ends of the fixed part so that the sliding part one fits at the top of the feed inlet and the sliding part two fits at the top of the discharge outlet. Then, the rotating parts of each part can be rotated so that the nozzle sprays towards the feed inlet and the discharge outlet, thereby reducing the spread of dust from the feed inlet and the discharge outlet. This has a dust reduction effect on the use of the sand making machine, reduces the spread of dust from the feed inlet and the discharge outlet to the working environment, and facilitates the use of the sand making machine.

[0014] 2. When using this utility model in a sand making machine, the permeable plate can be flipped towards the top of the feed inlet. At this time, the support plate supports the top of the feed inlet, so that the snap-fit ​​strip engages with the top of the fixing strip. Then, the sliding clip can be pushed to snap the snap-fit ​​strip and the fixing strip together, thereby locking the permeable plate at the top of the feed inlet. Then, the axial flow fan runs and blows air through the permeable plate into the feed inlet, so that the spray from the nozzle can be blown into the interior of the feed inlet. At the same time, the permeable plate blocking the top of the feed inlet can block the stones that are ejected from the feed inlet, preventing the stones from ejecting outwards and providing protection for the workers.

[0024] A fastener 120 is bolted to the side wall of the feed inlet 101. Sliding parts 121 and 130 are slidably fitted inside the fastener 120. A knob for locking the sliding parts 121 and 130 is provided on the side wall of the fastener 120. A rotating part 122 is rotatably connected inside the sliding part 121. Multiple nozzles 123 are provided on the top of the rotating part 122. The nozzles 123 are common stainless steel water nozzles. A connector 124 is provided on the side wall of the rotating part 122. The connector 124 is connected to a common external water pump through a rubber tube. A rotating shaft 125 is bolted to both ends of the rotating part 122. A locking bolt that fits the rotating shaft 125 is provided on the side wall of the fastener 120. The locking bolt can be used to lock the rotating shaft 125 after the rotating part 122 rotates.

[0025] Specifically, a vent plate 150 is rotatably connected to the side wall of the feed inlet 101. The vent plate 150 is made of common stainless steel plate, and a fixed frame 140 is fixed to the bottom of the vent plate 150 by bolts.

[0026] Furthermore, an axial flow fan 141 is installed inside the fixed frame 140. The axial flow fan 141 uses a common model on the market and is fitted to the bottom of the ventilation plate 150.

[0032] Working principle: Sliding parts 121 and 130, which are fitted to the fixed connector 120, are provided on the side wall of the feed inlet 101. Sliding parts 121 and 130 can be pulled out towards both ends of the fixed connector 120, causing sliding part 121 to engage with the top of the feed inlet 101 and sliding part 130 to engage with the top of the discharge outlet 102. Then, rotating parts 122 of each component cause the nozzles 123 to spray towards the feed inlet 101 and discharge outlet 102, thereby reducing the outward diffusion of dust from the feed inlet 101 and discharge outlet 102. This has a dust-reducing effect on the sand making machine, reducing the diffusion of dust from the feed inlet 101 and discharge outlet 102 into the working environment, and facilitating the use of the sand making machine. During the sand making process... When the sander is in use, the vent plate 150 can be flipped over to the top of the feed inlet 101. At this time, the support plate 151 supports the top of the feed inlet 101, so that the locking strip 152 engages with the top of the fixing strip 153. Then, the sliding clip 154 ​​can be pushed to lock the locking strip 152 and the fixing strip 153, thereby locking the vent plate 150 to the top of the feed inlet 101. Then, the axial flow fan 141 runs and blows air through the vent plate 150 into the feed inlet 101, so that the spray from the nozzle 123 can be blown into the interior of the feed inlet 101. At the same time, the vent plate 150 blocking the top of the feed inlet 101 can block the stones that are ejected from the feed inlet 101, preventing the stones from ejecting outwards and providing protection for the workers.
