Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to an asphalt concrete feeder. Background Art

[0002] The reference patent name is: An asphalt concrete loader (patent publication number: CN220011032U, patent publication date: 2023-11-14), including a base plate, a box body is provided above the base plate, and the box body is fixedly connected to the base plate through supporting legs arranged at the four corners of the bottom, and a material guide hopper is provided above the box body, and a crushing barrel is provided in the inner cavity of the box body, and a crushing assembly is provided in the crushing barrel. A material guide hose is connected to the center of the bottom wall of the box body, and a mounting base is provided below the material guide hose, and a feeding assembly is provided on the mounting base, and an adjustment assembly is provided below the feeding assembly, which can crush the raw materials before feeding. Therefore, during the feeding process, it is not easy to cause feeding blockage due to the large specifications of the raw materials, and its structure is relatively flexible, and the feeding angle can be adjusted, so there will be no limitations in actual use.

[0003] However, when implementing the above technical scheme, there are the following problems: the above scheme can achieve crushing and stirring of the materials inside the feeder during transportation to avoid blockage, but it is difficult to ensure that the limited diameter of the guide hopper will not cause blockage at a higher concrete flow rate when the material is introduced in the above scheme. After the device in the above scheme is put into use, the internal diameter of the guide hopper above it will be fixed. When the concrete material is introduced into the device through a pipeline by a mixer truck, the concrete has a certain flow rate. When the flow rate is too fast, the material inside the guide hopper cannot flow downward at the same flow rate due to the limitation of the diameter and accumulates, or the concrete itself has a low fluidity and is easy to accumulate at the guide hopper position, which will affect the subsequent concrete flow rate into the device. At the same time, too much accumulation will cause concrete overflow and waste. For this reason, the utility model provides an asphalt concrete feeder. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an asphalt concrete feeder, which solves the problem that when the asphalt concrete feeder is inside the concrete material introduction device, it will be blocked due to the limitation of the diameter of the material guide port, the introduction flow rate, the concrete's own fluidity and other problems, thereby affecting the subsequent introduction speed and even causing overflow.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: an asphalt concrete feeder, including a feeder body, a sealing cover is fixedly provided on the surface of the feeder body, a discharge trough is opened on the surface of the feeder body, and a dredging mechanism is provided between the feeder body and the discharge trough to dredge the concrete inside the discharge trough, and the dredging mechanism includes:

[0006] A dredging assembly is arranged between the discharge chute and the feeder body to realize the dredging of the raw materials, including a dredging frame fixed to the inside of the discharge chute, the internal rotation of the dredging frame is provided with a driving ring, the internal thread of the driving ring is connected with a dredging rod, the internal rotation of the feeder body is provided with a driving gear and a reciprocating wheel, a driving assembly is arranged between the reciprocating wheel and the feeder body to realize structural rotation, and a synchronization assembly is arranged between the driving gear and the driving ring to realize rotation synchronization;

[0007] The fixing component is arranged inside the discharge chute to fix the position of the discharge chute and the discharge pipe.

[0008] Preferably, the driving assembly includes a driving rod that rotates with the inside of the loader body, and a reversing assembly is provided between the driving rod and the reciprocating wheel to realize rotation reversal.

[0009] Preferably, the reversing assembly includes a reversing cone wheel fixed to one end of the reciprocating wheel, and a driving cone tooth is fixed on the surface of the driving rod.

[0010] Preferably, the synchronization assembly includes synchronization wheels fixed on the surfaces of the driving gear and the driving ring, and a synchronization belt is connected between the synchronization wheels.

[0011] Preferably, the fixing assembly includes a cylinder fixed to the surface of the loader body, and a piston rod is slidably connected to the interior of the cylinder.

[0012] Preferably, one end of the piston rod is fixedly connected to a fixing rod, and an elastic ring is slidably connected inside the fixing rod.

[0013] Beneficial Effects

[0014] The utility model provides an asphalt concrete feeder. Compared with the prior art, it has the following beneficial effects:

[0015] (1) The asphalt concrete feeder has a slidable unblocking rod disposed inside a discharge chute opened above the feeder body, and the unblocking rod is restricted to slide inside the unblocking frame by a thread, thereby limiting the position of the unblocking rod during use and allowing the unblocking rod to be quickly removed for cleaning after concrete feeding is completed, thereby facilitating maintenance. The unblocking rod moves up and down at the center of the discharge chute. When the amount of concrete inside the discharge chute reaches a certain level and causes a blockage, the up and down sliding of the unblocking rod can drive part of the concrete to move and cause a groove to be formed in the middle of the blockage through the movement, so that the concrete can continue to flow inside the discharge chute.

[0016] (2) The asphalt concrete feeder sets a driving bevel gear at the driving rod position of the motor that drives the concrete material to be crushed inside the feeder body, and drives the reciprocating wheel at the upper position inside the feeder body to rotate through the driving bevel gear. When the crushing structure starts to crush the concrete material, the reciprocating wheel will rotate synchronously. When the concrete mixer truck enters the feeder body and starts to move, there is no need to start independently. The simultaneous starting can effectively avoid the problem of high pressure on the driving dredging rod when starting after subsequent blockage, thereby ensuring the rapid flow of concrete.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides two technical solutions:

[0024] Embodiment 1

[0025] An asphalt concrete feeder includes a feeder body 1, which includes a bracket, a feeder, a support rotation, and a raw material crushing structure having the same structure as that in the reference patent, so as to realize the discharge of concrete materials at a certain height. A sealing cover 2 is fixedly provided on the surface of the feeder body 1, and a sealing strip is fixed at the contact position between the sealing cover 2 and the feeder body 1. A discharge trough 3 is opened on the surface of the feeder body 1, and a dredging mechanism 4 is provided between the feeder body 1 and the discharge trough 3 to realize the dredging of concrete inside the discharge trough 3. The dredging mechanism 4 includes:

[0026] A dredging component is arranged between the discharge chute 3 and the feeder body 1 to realize the dredging of the raw materials, including a dredging frame 41 fixed to the inside of the discharge chute 3. The surface of the dredging frame 41 is smooth, and the upper surface is arc-shaped to avoid a large amount of concrete residue. The internal rotation of the dredging frame 41 is provided with a driving ring 42, and the internal thread of the driving ring 42 is connected with a dredging rod 43. The internal rotation of the feeder body 1 is provided with a driving gear 44 and a reciprocating wheel 45. A driving component 5 is arranged between the reciprocating wheel 45 and the feeder body 1 to realize the rotation of the structure. The surface of the reciprocating wheel 45 is fixed with uneven teeth, and a gear is fixed in the middle. The surface of the driving gear 44 can mesh with the surface of the uneven teeth and the gear respectively. A synchronization component 6 is arranged between the driving gear 44 and the driving ring 42 to realize rotation synchronization;

[0027] A fixing component 7, which is arranged inside the discharge chute 3 to fix the position of the discharge chute 3 and the discharge pipe;

[0028] A slidable dredging rod 43 is arranged inside the discharge chute 3 opened above the feeder body 1, and the dredging rod 43 is restricted to slide inside the dredging frame 41 by a thread, thereby limiting the position of the dredging rod 43 during use and allowing the dredging rod to be quickly taken out for cleaning after the concrete loading is completed, which is convenient for maintenance. The dredging rod 43 moves up and down at the center of the discharge chute 3. When the concrete inside the discharge chute 3 reaches a certain amount and causes blockage, the up and down sliding of the dredging rod 43 can drive part of the concrete to move and cause a groove to be formed in the middle of the blockage through the movement, so that the concrete can continue to flow inside the discharge chute 3.

[0029] Embodiment 2

[0030] The main difference from the first embodiment is:

[0031] An asphalt concrete feeder, wherein the driving assembly 5 includes a driving rod 51 that rotates inside a feeder body 1, one end of the driving rod 51 is fixed to the output shaft of a three-phase asynchronous motor through a coupling, a reversing assembly 52 is provided between the driving rod 51 and a reciprocating wheel 45 to realize rotation reversal, the reversing assembly 52 includes a reversing cone wheel 521 fixed to one end of the reciprocating wheel 45, a driving bevel gear 522 is fixed to the surface of the driving rod 51, and the surface of the reversing cone wheel 521 contacts the surface of the driving bevel gear 522, the synchronization assembly 6 includes a synchronization wheel 61 fixed to the surface of a driving gear 44 and a driving ring 42, a synchronization belt 62 is transmission-connected between the synchronization wheels 61, and the fixing assembly 7 includes a cylinder 71 fixed to the surface of the feeder body 1, a piston rod 72 is slidably connected to the inside of the cylinder 71, and a fixing rod 73 is fixedly connected to one end of the piston rod 72 The surface of the fixing rod 73 is slidably connected to the inside of the feeder body 1. There are four fixing rods 73, three of which slide independently inside the feeder body 1 and are not fixedly connected to one end of the piston rod 72. The fixing rod 73 is slidably connected to the inside of the feeder body 1 with an elastic ring 74. The elastic ring 74 has a strong elastic force and is ring-shaped. A driving bevel gear 522 is set at the position of the driving rod 51 of the motor corresponding to the concrete material crushing motor inside the feeder body 1. The driving bevel gear 522 drives the reciprocating wheel 45 at the upper position inside the feeder body 1 to rotate, and then when the crushing structure starts to crush the concrete material, the reciprocating wheel 45 will rotate synchronously. When the concrete mixer enters the feeder body 1 and starts to move, there is no need to start independently. The simultaneous starting can effectively avoid the problem of the driving dredging rod 43 being subjected to high pressure when starting after subsequent blockage, thereby ensuring the rapid circulation of concrete.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] During operation, firstly, the pipe at the concrete outlet position of the mixer truck is placed inside the discharge chute 3, and the cylinder 71 is driven to prompt the piston rod 72 to move toward the center position of the discharge chute 3. The fixing rod 73 contacts the surface of the pipe and limits the movement of the pipe, and adjusts the unloading position. Then, the spiral rod and the corresponding motor of the crushing structure are started, and the concrete can begin to be poured into the inside of the feeder body 1. The start of the motor can drive the driving rod 51 to rotate. The rotation of the driving rod 51 prompts the reciprocating wheel 45 to rotate through the reversing assembly 52. ​​The contact between the teeth at different positions on the surface of the reciprocating wheel 45 and the surface of the driving gear 44 will drive the driving gear 44 to reciprocate, and then the driving ring 42 will reciprocate through the synchronous belt 62. Under the action of the thread, the dredging rod 43 will reciprocate inside the discharge chute 3 to ensure that there is a gap in the cylinder when the concrete is unloaded to avoid blockage.
