Description

Technical Field

[0001] This utility model relates to the field of filling device technology, and in particular to an adjustable road pothole filling device. Background Technology

[0002] The filling device is used to fill potholes in asphalt pavements. It consists of a vehicle body, a rotating shaft, wheels, a feed hopper, a liquefied petroleum gas (LPG) tank, an air hose, and a nozzle. When using the device, workers pour asphalt material into the feed hopper, then push the vehicle body, using the rotating shaft and wheels to move the material into the potholes. The workers then level the asphalt material, open the valve on the air hose, and turn on the nozzle. The LPG is ignited electronically and sprayed onto the asphalt material, melting it and fusing it with the asphalt pavement, thus filling the potholes.

[0003] The inventors discovered in their daily work that when the filling device is in use, the material falls from the feed hopper into the potholes of the road surface through the free fall of asphalt material. When the vehicle is pushed quickly by hand, the falling speed of the material cannot be increased, which may result in a poor filling effect on the potholes of the road surface. Utility Model Content

[0004] The purpose of this invention is to solve the problem that, in actual use, when the material falls from the feed hopper into the potholes of the road surface through the free fall of asphalt material, the falling speed of the material cannot be adjusted when the vehicle is pushed quickly by hand, which may result in poor filling effect of the potholes. Therefore, an adjustable pothole filling device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable road pothole filling device, comprising a vehicle body, a rotating shaft rotatably connected to one end of the vehicle body via a bearing, wheels fixedly connected to both ends of the rotating shaft, a liquefied tank and a feeding hopper fixedly connected to the upper end of the vehicle body, the feeding hopper penetrating the vehicle body, a flame head fixedly connected to the lower end of the vehicle body, an air pipe fixedly connected between the flame head and the liquefied tank, the air pipe penetrating the vehicle body, and an adjusting assembly provided on the inner wall of the feeding hopper, the adjusting assembly including a drive rod rotatably connected to the inner wall of the feeding hopper via a bearing, and multiple evenly distributed adjusting blades fixedly connected to the arc surface of the drive rod.

[0006] The effect achieved by the above components is as follows: by setting the adjustment component, when adjusting the feeding speed of the hopper, the worker pushes the vehicle body, and through the transmission mechanism, the drive rod rotates, which in turn rotates the adjustment blade, thereby feeding the asphalt material in the hopper. When the worker pushes the vehicle body faster, through the transmission mechanism, the drive rod rotates faster, which in turn rotates the adjustment blade, thereby feeding the asphalt material in the hopper faster, thus achieving the effect of adjusting the feeding speed of the hopper as much as possible.

[0007] Preferably, a sleeve is fixedly connected to the left end of the feed hopper, and a first sprocket is provided at the other end of the sleeve via a bearing. A square rod is slidably inserted into the front of the first sprocket and inserted into the drive rod.

[0008] The effect achieved by the above components is as follows: when the square rod is inserted into the drive rod, the first sprocket on the sleeve rotates, thereby driving the drive rod to rotate.

[0009] Preferably, a second sprocket is fixedly connected to the arc surface of the rotating shaft, and a chain is provided between the second sprocket and the first sprocket.

[0010] The effect achieved by the above components is as follows: the worker pushes the vehicle body, causing the wheels to rotate, causing the rotating shaft to rotate, causing the second sprocket to rotate, and through chain transmission, causing the first sprocket to rotate.

[0011] Preferably, the sleeve is fitted onto the arc surface of the drive rod, and the surface of the square rod is provided with protrusions.

[0012] The effect achieved by the above-mentioned components is that when it is not necessary to control the feeding of asphalt materials, the square rod can be pulled out, thereby disengaging the first sprocket from the drive rod.

[0013] Preferably, a cleaning assembly is provided at the upper end of the vehicle body. The cleaning assembly includes a sliding hole formed at the upper end of the vehicle body. A lead screw is rotatably connected to the inner wall of the sliding hole by means of a bearing. A grooved T-shaped rod is slidably connected to the inner wall of the sliding hole. An installation block is slidably connected to the inner wall of the grooved T-shaped rod. Brush bristles are fixedly connected to the lower end of the installation block. The grooved T-shaped rod is threadedly connected to the lead screw.

[0014] The effect achieved by the above components is as follows: the lead screw continuously rotates forward and backward, causing the grooved T-shaped rod in the sliding hole to move back and forth. The worker slowly pushes the vehicle body, and the brush bristles on the mounting block move back and forth before moving forward, so that the brush bristles can remove the debris in the pothole.

[0015] Preferably, a motor is installed at one end of the vehicle body, and the motor controls the rotation of the lead screw.

[0016] The effect achieved by the above components is as follows: the motor is started, and the motor is connected to the lead screw through the reducer and coupling, so that the motor can continuously rotate in both directions, causing the lead screw to continuously rotate in both directions.

[0017] Preferably, a spring is fixedly connected to the upper end of the mounting block, and the other end of the spring is fixed to the slotted T-shaped rod.

[0018] The effect achieved by the above components is as follows: by setting a spring, the brush bristles come into contact with the ground, the spring is compressed, and its reverse force pushes the mounting block, so that the brush bristles make full contact with the ground.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting an adjustment component, when adjusting the feeding speed of the hopper, the worker pushes the vehicle body, and through the transmission mechanism, the drive rod rotates, causing the adjustment blade to rotate, thereby feeding the asphalt material in the hopper. When the worker pushes the vehicle body faster, the transmission mechanism causes the drive rod to rotate faster, causing the adjustment blade to rotate faster, thus increasing the feeding speed of the asphalt material in the hopper. This achieves the effect of adjusting the feeding speed of the hopper as much as possible, solving the problem that since the material falls from the hopper into the potholes of the road surface through free fall, the falling speed of the material cannot be increased when the vehicle body is pushed fast by the worker, which may result in poor filling effect on the potholes.

[0028] Reference Figure 2 and Figure 4 as well as Figure 5 As shown, in this embodiment: the adjusting component 2 includes a drive rod 22 rotatably connected to the inner wall of the feed hopper 4 via a bearing. Multiple evenly distributed adjusting blades 21 are fixedly connected to the arc surface of the drive rod 22. By setting the adjusting component 2, when adjusting the feeding speed of the feed hopper 4, the worker pushes the vehicle body 1, causing the drive rod 22 to rotate via a transmission mechanism, which in turn causes the adjusting blades 21 to rotate, thereby feeding the asphalt material from the feed hopper 4. When the worker pushes the vehicle body 1 faster, the transmission mechanism causes the drive rod 22 to rotate faster, which in turn causes the adjusting blades 21 to rotate faster, thus increasing the feeding speed of the asphalt material from the feed hopper 4, thereby maximizing the adjustment of the feeding speed of the feed hopper 4. A sleeve 23 is fixedly connected to the left end of the feed hopper 4, and the other end of the sleeve 23 is provided with a rotatable connecting element via a bearing. The first sprocket 24 has a square rod 25 slidably inserted on its front side. The square rod 25 is inserted into the drive rod 22. When the square rod 25 is inserted into the drive rod 22, the first sprocket 24 on the sleeve 23 rotates, causing the drive rod 22 to rotate. The arc surface of the rotating shaft 8 is fixedly connected to the second sprocket 27. A chain 26 is provided between the second sprocket 27 and the first sprocket 24. When the worker pushes the vehicle body 1, the wheel 7 rotates, causing the rotating shaft 8 to rotate, causing the second sprocket 27 to rotate. Through the chain 26, the first sprocket 24 rotates. The sleeve 23 is fitted onto the arc surface of the drive rod 22. The surface of the square rod 25 is provided with protrusions. When it is not necessary to control the asphalt material feeding, the square rod 25 is pulled out, so that the first sprocket 24 is disconnected from the drive rod 22.

[0029] Reference Figure 1 and Figure 2 as well as Figure 3As shown in this embodiment: a cleaning component 3 is provided at the upper end of the vehicle body 1. The cleaning component 3 includes a sliding hole 31 opened at the upper end of the vehicle body 1.

A mounting block 35 is slidably connected to the inner wall of the grooved T-shaped rod 34. A brush bristle 36 is fixedly connected to the lower end of the mounting block 35. The grooved T-shaped rod 34 is threadedly connected to the lead screw 32. The lead screw 32 continuously rotates forward and backward, causing the grooved T-shaped rod 34 in the sliding hole 31 to move back and forth. The worker slowly pushes the vehicle body 1, and the brush bristle 36 on the mounting block 35... After moving left and right, it moves forward, so that the bristles 36 can remove debris and stones in potholes. A motor 33 is installed at one end of the vehicle body 1. The motor 33 controls the rotation of the lead screw 32. When the motor 33 is started, it is connected to the lead screw 32 through a reducer and a coupling, so that the motor 33 keeps rotating forward and backward, causing the lead screw 32 to keep rotating forward and backward. A spring 37 is fixedly connected to the upper end of the mounting block 35. The other end of the spring 37 is fixed to the grooved T-shaped rod 34. By setting the spring 37, the bristles 36 contact the ground, the spring 37 is compressed, and its reverse force pushes the mounting block 35, so that the bristles 36 make full contact with the ground.

[0030] Working principle:

[0031] When using the filling device, the worker pours asphalt material into the feed hopper 4, then pushes the vehicle body 1, moving it with the help of the rotating shaft 8 and wheels 7, so that the material falls into the potholes on the asphalt road surface. The worker then levels the asphalt material, opens the valve on the gas pipe 6, and turns on the burner head 9, igniting the liquefied gas electronically, which is then sprayed onto the asphalt material, melting it and fusing it with the asphalt road surface, thus filling the potholes. To adjust the feeding speed of the feed hopper 4, the square rod 25 is inserted into the drive rod 22. The worker pushes the vehicle body 1, causing the wheels 7 to rotate, which in turn rotates the rotating shaft 8, causing the second sprocket 27 to rotate. Through the chain 26, the first sprocket 24 on the sleeve 23 rotates, causing the drive rod 22 to rotate, which in turn rotates the adjusting blade 21, thus discharging the asphalt material from the feed hopper 4. As the worker pushes the vehicle body 1 faster, the wheels 7 rotate faster, the rotating shaft 8 rotates faster, and the second sprocket 27 rotates faster. This causes the drive rod 22 to rotate faster, which in turn causes the adjusting blade 21 to rotate faster, thus speeding up the discharge of asphalt material from the feed hopper 4. This achieves the goal of regulating the discharge speed of the feed hopper 4 as much as possible. When it is not necessary to control the discharge of asphalt material, the square rod 25 is pulled out, which disconnects the first sprocket 24 from the drive rod 22. The motor 33 is started by the controller (the motor 33 used in this application can be a Huilongfa 1.5KW model). The motor 33 is connected to the lead screw 32 through the reducer and coupling, allowing the motor 33 to continuously rotate forward and backward, which in turn causes the lead screw 32 to continuously rotate forward and backward, causing the grooved T-shaped rod 34 in the sliding hole 31 to move back and forth. The worker slowly pushes the vehicle body 1, and the brush bristles 36 on the mounting block 35 move back and forth before moving forward, so that the brush bristles 36 can remove debris from the potholes. By setting the spring 37, the brush bristles 36 contact the ground, and the spring 37 is compressed. Its reverse force pushes the mounting block 35, so that the brush bristles 36 can fully contact the ground.
