Technical Field

[0001] This utility model relates to the technical field of sand conveying equipment, specifically a sand feeding device for construction sites. Background Technology

[0002] In construction site operations, sand loading is a fundamental yet labor-intensive task. Traditional loading methods rely mainly on manual labor using shovels and other tools to shovel sand into the mixer or lift it to a designated height, resulting in low efficiency. To overcome the drawbacks of manual labor, conveyor belts are commonly used for loading. However, during sand loading operations, bridging or adhesion to the tank walls is prone to occur, leading to uneven loading or even complete blockages. This requires frequent manual intervention and clearing, severely impacting the continuity and overall efficiency of the loading operation.

[0003] Therefore, those skilled in the art have proposed a sand loading device for construction sites to solve the aforementioned problems. Utility Model Content

A conveyor belt is driven to the surface of the two drive rollers. Evenly distributed baffles are fixedly connected to the surface of the conveyor belt. A motor is fixedly connected to one side of the housing. The output shaft of the motor passes through the housing and is fixedly connected to one end of one of the drive rollers. The auxiliary structure includes a turntable rotatably connected to one side of the housing. A drive shaft coaxial with the motor output shaft is fixedly connected to the surface of the turntable. The other end of the drive shaft passes through the housing and is fixedly connected to one end of the adjacent drive roller.

[0006] Preferably, a drive rod is eccentrically fixed to the side of the turntable away from the outer casing.

[0007] Preferably, the auxiliary structure further includes a fixing rod fixedly connected to the surface of the housing and located above the motor. A fixing block is fixedly connected to the side of the fixing rod away from the housing, and a rotating rod is provided on the other side of the fixing rod. A connecting plate is fixedly connected to the other end of the rotating rod.

[0008] Preferably, a trigger rod is fixedly connected to the side of the connecting plate away from the rotating rod, and the other end of the trigger rod extends to the surface of the turntable and contacts the surface of the turntable.

[0009] Preferably, the surface of the rotating rod is fixedly connected to two symmetrically distributed connecting rods, and the other end of the connecting rod is fixedly connected to a striking ball, which is in contact with the surface of the storage tank.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 A sand loading device for construction sites, comprising: The outer shell 1 has a storage tank 101 connected to its surface, a conveying structure is provided inside the outer shell 1, and an auxiliary structure 2 is provided on the surface of the outer shell 1. The conveying structure includes two drive rollers 303 rotatably connected to the inner wall of the outer shell 1. A conveyor belt 3 is connected to the surface of the two drive rollers 303. Evenly distributed baffles 302 are fixedly connected to the surface of the conveyor belt 3. A motor 301 is fixedly connected to one side of the outer shell 1. The output shaft of the motor 301 passes through the outer shell 1 and is fixedly connected to one end of one of the drive rollers 303. The auxiliary structure 2 includes a turntable 201 rotatably connected to one side of the housing 1. A drive shaft coaxially arranged with the output shaft of the motor 301 is fixedly connected to the surface of the turntable 201. The other end of the drive shaft passes through the housing 1 and is fixedly connected to one end of the adjacent drive roller 303.

[0018] By starting the motor 301, the drive roller 303 connected to it can be driven to rotate, which in turn drives the conveyor belt 3 to drive. With the setting of another drive roller 303, the transmission of the conveyor belt 3 can be stably achieved. The storage tank 101 can be used to store sand. Under the action of gravity, the sand falls into the inside of the outer shell 1 and falls above the conveyor belt 3. The baffle 302 can prevent the sand from sliding backward during the lifting process. At the same time, as the motor 301 drives the connected drive roller 303 to rotate, it can synchronously drive the drive shaft to rotate, which in turn drives the turntable 201 to rotate synchronously.

[0019] Please see Figure 1-5A drive rod 202 is eccentrically fixed to the side of the turntable 201 away from the outer casing 1.

[0020] The auxiliary structure 2 also includes a fixing rod 207 fixedly connected to the surface of the housing 1 and located above the motor 301. A fixing block 206 is fixedly connected to the side of the fixing rod 207 away from the housing 1, and a rotating rod 205 is provided on the other side of the fixing rod 207. A connecting plate 204 is fixedly connected to the other end of the rotating rod 205.

[0021] A trigger rod 203 is fixedly connected to the side of the connecting plate 204 away from the rotating rod 205. The other end of the trigger rod 203 extends to the surface of the turntable 201 and contacts the surface of the turntable 201.

[0022] Two symmetrically distributed connecting rods 210 are fixedly connected to the surface of the rotating rod 205. A striking ball 211 is fixedly connected to the other end of the connecting rod 210. The striking ball 211 is in contact with the surface of the storage tank 101.

[0023] A connecting shaft 208 is fixedly connected to one end of the rotating rod 205 away from the connecting plate 204. The other end of the connecting shaft 208 passes through the fixing rod 207 and the fixing block 206 in sequence and is rotatably connected to the inner wall of the fixing block 206. A spring 209 is fixedly connected to the surface of the connecting shaft 208. The other end of the spring 209 is fixedly connected to the inner wall of the fixing block 206.

[0024] During the rotation of turntable 201, the drive rod 202 can be driven to rotate synchronously. When the drive rod 202 rotates with turntable 201, it can push trigger rod 203 to drive connecting plate 204 to rotate around rotating rod 205. At the same time, during the rotation, it can drive connecting shaft 208 to rotate synchronously and tighten spring 209. During the rotation of rotating rod 205, it can drive connecting rod 210 to move striking ball 211 away from storage tank 101. Until the drive rod 202 and trigger rod 203 are separated, spring 209 drives connecting shaft 208 to reset, and then drives striking ball 211 to reset. When striking ball 211 resets, it can strike the surface of storage tank 101, and shake the sand stored inside to fall by the form of knocking vibration, so as to avoid the sand sticking together and causing incomplete feeding. At the same time, the vibration method avoids the situation where the sand is stuck together and blocked, affecting the feeding.

[0025] Please see Figure 1-5 The inner wall of the outer casing 1 is fixedly connected with two symmetrically distributed guide plates 102 located below the conveyor belt 3, and the surface of the outer casing 1 is provided with a slag discharge port 103. The guide plate 102 is set to collect the fallen sand and discharge it through the slag discharge port 103. The workers can collect the fallen residual sand by setting a hopper below the slag discharge port 103.

[0026] Working principle: The storage tank 101 is designed for storing sand. Under the influence of gravity, the sand falls into the interior of the outer shell 1 and then onto the conveyor belt 3. The baffle 302 prevents the sand from sliding backward during the lifting process. At the same time, the outer shell 1 prevents dust from being generated during the conveying process. By starting the motor 301, the drive roller 303 connected to it can be rotated, which in turn drives the conveyor belt 3 to realize the sand feeding operation. During this process, the auxiliary structure 2 can be used to tap the surface of the storage tank 101 to shake the sand stored inside out through the tapping vibration, so as to avoid the sand sticking together and causing incomplete feeding. At the same time, the vibration method avoids the problem of sand sticking together and blocking the discharge, which is a problem in traditional methods.
