An asphalt concrete feeding machine

Abstract

This utility model discloses an asphalt concrete feeding machine, relating to the field of building material production technology. It includes a base plate, on the top of which a conveyor frame is rotatably mounted via an adjusting component. A conveyor belt is rotatably mounted inside the conveyor frame. A discharge port is fixedly opened at the bottom of the end of the conveyor frame, and a flow guiding component is provided at the bottom of the discharge port. During use, the motor is started, ultimately driving the flow guiding plate to reciprocate, thereby guiding the material falling into the connecting frame through the discharge port and dispersing it into the mixer. This prevents material from falling to the same position, solving the problem in existing asphalt concrete feeding machines where, due to the fixed positions of the feeding machine and mixer, material continuously falls to the same location during discharge. In this case, the mixer needs to increase the mixing time to disperse raw materials of different sizes in the same area, severely affecting the mixing effect.

Description

Technical Field

[0001] This utility model relates to the field of building material production technology, and in particular to an asphalt concrete feeding machine. Background Technology

[0002] Asphalt concrete is a building material made by mixing crushed stone, sand, mineral powder and asphalt in a certain proportion. It is mainly used for road paving. In production, the mixer is at a certain height from the ground for easy unloading. To facilitate the input of raw materials, a feeder is used to mix the materials with the mixer.

[0003] The existing patent publication number CN218930743U, entitled "An Asphalt Concrete Feeding Machine", proposes that the asphalt concrete feeding machine is detachably connected and fixed between the main shaft and the rotating rod. Therefore, when disassembling the main shaft and the spiral blade, it is not necessary to disassemble the bearing seat and sealing structure that are fixed together with the material box, making it more convenient to replace them.

[0004] However, in the process of using the asphalt concrete feeding machine disclosed in the above patent, since the positions of the feeding machine and the mixer are fixed, the material will continuously fall to the same position when discharging. At this time, the mixer needs to increase the mixing time to disperse the raw materials of different sizes in the same area, which seriously affects the mixing effect. Therefore, it is necessary to propose an asphalt concrete feeding machine to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an asphalt concrete feeding machine to solve the problem mentioned in the background art that, during the use of existing asphalt concrete feeding machines, because the positions of the feeding machine and the mixer are fixed, the material will continuously fall to the same position during discharge. At this time, the mixer needs to increase the mixing time to disperse the raw materials of different sizes in the same area, which seriously affects the mixing effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an asphalt concrete feeding machine, comprising a base plate, a conveyor frame rotatably mounted on the top of the base plate via an adjustment component, a conveyor belt rotatably mounted inside the conveyor frame, a discharge port fixedly opened at the bottom of the end of the conveyor frame, and a flow guiding component mounted at the bottom of the discharge port;

[0007] The flow guiding assembly includes a connecting frame, which is fixedly installed at the bottom of the discharge port. A rotating shaft is rotatably installed inside the connecting frame, and a flow guide plate is fixedly installed on the outer ring of the rotating shaft. A gear is fixedly connected to one end of the rotating shaft that movably passes through the outer side of the connecting frame. A horizontal column is fixedly installed on the side of the connecting frame. A sliding groove is opened inside the horizontal column, and a reciprocating screw is rotatably installed inside the sliding groove. A movable block is threadedly connected to the outer ring of the reciprocating screw, and a rack is fixedly installed at the bottom of the movable block. A motor is fixedly installed at the end of the horizontal column, and the output end of the motor movably extends into the sliding groove and is fixedly connected to the reciprocating screw. The rack and the gear mesh with each other.

[0008] Preferably, the surface of the conveyor belt is fixedly provided with a plurality of baffles that are evenly arranged.

[0009] Preferably, in the initial state, the guide plate is in a vertical position.

[0010] Preferably, the adjustment assembly includes a U-shaped frame one and a U-shaped frame two, which are respectively fixedly installed at both ends of the top of the base plate. The conveyor frame and the U-shaped frame one are rotatably connected by a pivot pin. Both ends of the U-shaped frame two are fixedly provided with lifting grooves. An electric push rod is fixedly installed at the bottom of the lifting groove. A lifting block is fixedly connected to the telescopic end of the electric push rod. A lifting shaft is fixedly installed on the side of the lifting block. Adjustment grooves are fixedly installed on both sides of the conveyor frame. The end of the lifting shaft away from the lifting block extends movably into the interior of the adjustment groove.

[0011] Preferably, a crusher is fixedly installed on the top of the end of the conveyor frame away from the feed inlet.

[0012] Preferably, the lifting block and the lifting groove are adapted to each other, and the movable block and the sliding groove are adapted to each other.

[0013] Preferably, drive wheels are rotatably provided at each of the four corners of the bottom of the base plate.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the process of using this utility model, the motor is started, which drives the reciprocating screw to rotate, thereby driving the moving block and rack to move back and forth, which in turn drives the gear and rotating shaft to rotate back and forth, and finally drives the guide plate to swing back and forth. This allows the guide plate to guide the material falling into the connecting frame through the discharge port, so that it is dispersed and fed into the interior of the mixer, avoiding the material falling in the same position. This solves the problem that in the existing asphalt concrete feeding machine, because the positions of the feeding machine and the mixer are fixed, the material will continuously fall into the same position when discharging. At this time, the mixer needs to increase the mixing time to disperse the raw materials of different sizes in the same area, which seriously affects the mixing effect.

[0016] 2. When the height of the mixer is different, start the electric push rod to drive the lifting block and lifting shaft to move up and down. Through the setting of the adjustment groove, the lifting shaft that moves up and down drives the conveyor frame to rotate around the central axis of the shaft pin by a certain angle, thereby adjusting the feeding height of the conveyor frame and improving the flexibility of the device.

[0023] 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.

[0024] This utility model provides, for example Figures 1-5The asphalt concrete feeding machine shown includes a base plate 1. A conveyor frame 7 is rotatably mounted on the top of the base plate 1 via an adjusting component. A conveyor belt 9 is rotatably mounted inside the conveyor frame 7. Several evenly arranged baffles 10 are fixedly mounted on the surface of the conveyor belt 9. A discharge port 11 is fixedly opened at the bottom of the end of the conveyor frame 7. In use, the asphalt concrete raw materials are conveyed by the conveyor belt 9 and fall into the external mixer through the discharge port 11. Considering that in the use of existing asphalt concrete feeding machines, since the positions of the feeding machine and the mixer are fixed, the material will continuously fall into the same position when discharging. At this time, the mixer needs to increase the mixing time to disperse the raw materials of different sizes in the same area, which seriously affects the mixing effect. Therefore, the present invention provides a flow guiding component at the bottom of the discharge port 11. By installing the flow guiding component, the material is dispersed into the interior of the mixer, avoiding the material falling into the same position.

[0025] Specifically, the flow guiding component includes a connecting frame 12, which is fixedly installed at the bottom of the discharge port 11. A rotating shaft 13 is rotatably installed inside the connecting frame 12. A flow guide plate 14 is fixedly installed on the outer ring of the rotating shaft 13. A gear 15 is fixedly connected to one end of the rotating shaft 13 that movably passes through the outer side of the connecting frame 12. A horizontal column 16 is fixedly installed on the side of the connecting frame 12. A sliding groove is opened inside the horizontal column 16. A reciprocating screw is rotatably installed inside the sliding groove. A movable block is threadedly connected to the outer ring of the reciprocating screw. The movable block and the sliding groove are adapted to each other. A rack 18 is fixedly installed at the bottom of the movable block. A motor 17 is fixedly installed at the end of the horizontal column 16. The output end of the motor 17 movably extends into the interior of the sliding groove and is fixedly connected to the reciprocating screw. The rack 18 and the gear 15 mesh with each other.

[0026] The motor 17 is started, which drives the reciprocating screw to rotate, thereby driving the movable block and rack 18 to move back and forth, which in turn drives the gear 15 and rotating shaft 13 to rotate back and forth, and finally drives the guide plate 14 to swing back and forth. This allows the guide plate 14 to guide the material falling into the connecting frame 12 through the discharge port 11, so that it is dispersed and fed into the interior of the mixer, preventing the material from falling in the same position. This solves the problem that in the existing asphalt concrete feeding machine, because the positions of the feeding machine and the mixer are fixed, the material will continuously fall into the same position when discharging. At this time, the mixer needs to increase the mixing time to disperse the raw materials of different sizes in the same area, which seriously affects the mixing effect.

[0027] Furthermore, the adjustment assembly includes a U-shaped frame 2 and a U-shaped frame 3, which are respectively fixedly installed at both ends of the top of the base plate 1. The conveyor frame 7 and the U-shaped frame 2 are rotatably connected by a pivot pin. Lifting grooves 4 are fixedly opened at both ends of the U-shaped frame 3. An electric push rod 5 is fixedly installed at the bottom of the lifting groove 4. A lifting block is fixedly connected to the telescopic end of the electric push rod 5. The lifting block and the lifting groove 4 are adapted to each other. A lifting shaft 6 is fixedly installed on the side of the lifting block. Adjustment grooves 8 are fixedly opened on both sides of the conveyor frame 7. The end of the lifting shaft 6 away from the lifting block extends movably into the interior of the adjustment groove 8.

[0028] Specifically, when the height of the mixer is different, the electric push rod 5 is activated, which drives the lifting block and the lifting shaft 6 to move up and down. Through the setting of the adjustment groove 8, the lifting shaft 6, which moves up and down, drives the conveyor frame 7 to rotate around the central axis of the shaft pin by a certain angle, thereby adjusting the feeding height of the conveyor frame 7 and improving the flexibility of the device.

[0029] Furthermore, in the initial state, the guide plate 14 is in a vertical position, which allows the material to fall vertically into the interior of the mixer.

[0030] Furthermore, a crusher 19 is fixedly installed on the top of the end of the conveyor frame 7 away from the discharge port 11. The crusher 19 is used to crush the material and achieve the multi-functional effect of the device. The working principle of the crusher 19 is a well-known technology. The appropriate model is selected according to the actual use, and will not be described in detail.

[0031] Furthermore, drive wheels are rotatably installed at the four corners of the bottom of the base plate 1, which facilitates the displacement of the device.

[0032] Working principle: During use, the asphalt concrete raw materials are conveyed by the conveyor belt 9 and fall into the external mixer through the discharge port 11. At this time, the motor 17 is started, which drives the reciprocating screw to rotate, thereby driving the movable block and rack 18 to move back and forth, which in turn drives the gear 15 and rotating shaft 13 to rotate back and forth, and finally drives the guide plate 14 to swing back and forth. This allows the guide plate 14 to guide the material falling into the connecting frame 12 through the discharge port 11, so that it is dispersed into the mixer and prevents the material from falling in the same position. When the height of the mixer is different, the electric push rod 5 is started, which drives the lifting block and lifting shaft 6 to move up and down. Through the setting of the adjustment groove 8, the up and down moving lifting shaft 6 drives the conveyor frame 7 to rotate around the central axis of the shaft pin by a certain angle, thereby adjusting the discharge height of the conveyor frame 7 to accommodate mixers of different heights.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
