Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand and gravel crushing technology, specifically to a sand and gravel crushing and conveying device. Background Technology
[0002] Sand and gravel processing refers to the process of crushing, screening, washing and other steps to produce sand and gravel that meet different specifications through a series of mechanical processing techniques. It is widely used in industries such as construction, roads, railways, concrete, and decoration. Crushing and conveying devices are required in the sand and gravel processing process to crush and transport the sand and gravel.
[0003] Referring to patent publication number CN207478676U, a sand and gravel crushing and conveying device includes a base plate. A support rod is fixedly connected to the left side of the upper surface of the base plate. A crushing box is placed on top of the base plate, and the end of the support rod away from the base plate is fixedly connected to the left side of the bottom surface of the crushing box. A first motor is fixedly connected to the middle of the right side of the crushing box. This sand and gravel crushing and conveying device can drive the transmission rod and crushing rod to rotate when the first motor is running, thereby crushing the sand and gravel material fed from the feed hopper. It can smoothly discharge the sand and gravel material into the interior of the discharge rack, avoiding the accumulation of a large amount of sand and gravel material during use and improving the discharge efficiency of the device. For conveying the crushed sand and gravel material, it can restrict and stabilize the position of the first and second rollers, preventing some sand and gravel material from slipping during conveying. The right end of the conveying device can be adjusted, improving the adjustability of the device.
[0004] While the above solution can transport sand and gravel, after crushing the sand and gravel, the sand and gravel fall directly onto the conveying device, and there is a certain drop between the conveying device and the crushing box. This causes the sand and gravel to generate a large amount of dust due to the drop between the sand and gravel and the conveying mechanism, which in turn affects the surrounding environment.
[0005] Based on this, this utility model designs a sand and gravel crushing and conveying device to solve the problem. Utility Model Content

A conveyor frame is provided on the left side of the machine box. A third motor is fixedly installed on the front of the conveyor frame. Two rotating shafts are rotatably connected to the inner wall of the conveyor frame through two sets of bearings. The front end of one of the rotating shafts is fixedly installed to the output end of the third motor. The two rotating shafts are connected by a conveyor belt.
[0008] Preferably, a baffle is provided above the conveyor frame, and the inner wall of the baffle is fixedly installed on the outer surface of the diversion ring.
[0009] Preferably, the conveyor frame is located directly below the diversion ring.

A water tank 203 is fixedly installed on the bottom surface of the casing 1. A water pump 204 is fixedly installed on the inner bottom wall of the water tank 203. A conduit 205 is fixedly installed at the output end of the water pump 204. The left end of the conduit 205 passes through the water tank 203 and is fixedly connected to the upper surface of the diverter ring 210. A conveyor frame 3 is provided on the left side of the casing 1. A third motor 301 is fixedly installed on the front of the conveyor frame 3. Two rotating shafts 303 are rotatably connected to the inner wall of the conveyor frame 3 through two sets of bearings. The front end of one of the rotating shafts 303 is fixedly installed to the output end of the third motor 301. The two rotating shafts 303 are connected by a conveyor belt 302.
[0024] Please see Figure 3 A baffle 4 is provided above the conveyor frame 3. The inner wall of the baffle 4 is fixedly installed on the outer surface of the diversion ring 210. The baffle 4 can block the dust, so that the atomizing nozzle 211 can wet the dust in time and reduce the dust splashing.
[0025] Please see Figure 1 The conveyor frame 3 is located directly below the diversion ring 210, which can ensure that the discharge pipe 202 can discharge materials accurately and prevent sand and gravel from being discharged to the wrong position.
[0026] Please see Figure 2The machine housing 1 is equipped with two guide plates 6 inside. The two guide plates 6 are fixedly installed on the inner wall of the machine housing 1 on the side that is far away from each other. The guide plates 6 can guide large pieces of raw materials in a concentrated manner so that the raw materials can fall between the crushing rollers 102.
[0027] Please see Figure 1 The outer surfaces of the two gears 103 are covered with a protective cover 5. The left side of the protective cover 5 is fixedly installed with the right side of the chassis 1. The protective cover 5 can protect the gears 103 and prevent them from being damaged.
[0028] Please see Figure 2 Fixing strips 206 are fixedly installed on both the left and right sides of the water tank 203. The upper surface of each fixing strip 206 is fixedly installed to the bottom surface of the chassis 1.

[0029] Please see Figure 2 A water inlet 207 is provided on the right side of the water tank 203. Water can be easily added to the inside of the water tank 203 through the water inlet 207 to ensure that water can be supplied to the atomizing nozzle 211.
[0030] The implementation principle of the sand and gravel crushing and conveying device in this application embodiment is as follows: During use, the raw material is placed inside the casing 1. The guide plate 6 guides the raw material, causing it to fall between two crushing rollers 102. The first motor 104 is started, driving the crushing rollers 102 to rotate. Under the action of two gears 103, the crushing rollers 102 crush the raw material, which falls inside the guide seat 209. The second motor 201 is started, driving the spiral conveyor shaft 208 to rotate. The spiral conveyor shaft 208 pushes the falling sand and gravel, allowing it to fall onto the conveyor belt 302 through the discharge pipe 202. The third motor 301 is started, driving the rotating shaft 303 to rotate, causing the conveyor belt 302 to rotate and convey the falling sand and gravel. Simultaneously, the water pump 204 draws water from the water tank 203, allowing the water to enter the diversion ring 210 through the water conduit 205. This allows multiple atomizing nozzles 211 to simultaneously wet the flying dust, reducing dust generation.
