Description

Technical Field

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

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering. Concrete has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability and a wide range of strength grades. These characteristics make its use very wide.

[0003] A search of CN220011032U discloses an asphalt concrete loader, which includes a base plate, a box body is provided above the base plate, the box body is fixedly connected to the base plate through supporting legs provided at the four corners of the bottom, a material guide hopper is provided above the box body, a crushing barrel is provided in the inner cavity of the box body, a crushing assembly is provided in the crushing barrel, a material guide hose is connected at the center of the bottom wall of the box body, a mounting base is provided below the material guide hose, a feeding assembly is provided on the mounting base, and an adjustment assembly is provided below the feeding assembly. The utility model can crush the raw materials before feeding, so it is not easy to cause feeding blockage due to the large specifications of the raw materials during the feeding process, and its structure is relatively flexible, and the feeding angle can be adjusted, so there will be no limitations in actual use.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] According to the above-mentioned asphalt concrete feeder, the device transfers the crushed asphalt concrete to the feed trough through a material guide hose, but the material guide hose may bend during the transportation process, thereby reducing the transmission efficiency, and the material guide hose is cylindrical when viewed from the middle, so asphalt concrete is easily accumulated on its inner wall during the transportation process.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0008] An asphalt concrete feeding machine includes a bottom plate, a crushing box and a feeding pipe. A side plate is installed on one side wall above the bottom plate. A pushing mechanism is arranged above the bottom plate, and the pushing mechanism is used to push the feeding pipe to change the angle. A crushing box is arranged above the bottom plate. Support legs are fixedly installed around the bottom of the crushing box, and the other ends of the four support legs are fixedly connected to the bottom plate. A crushing mechanism is arranged in the inner cavity of the crushing box, and the crushing mechanism is used to crush asphalt concrete. A first feeding port is arranged above the crushing box, and a first discharging port is arranged at the bottom. A guiding plate is arranged below the first discharging port. A sliding mechanism is arranged at the bottom of the crushing box, and the sliding mechanism is used to drive the guiding plate to move. A second feeding port is arranged above one side of the feeding pipe close to the crushing box, and a second discharging port is arranged below the other end of the feeding pipe, and a first motor is arranged at the port. By placing the asphalt concrete into the first feeding port and starting the second motor, the stirring mechanism can be driven to crush the asphalt concrete, which can avoid the blockage caused by larger asphalt concrete to a certain extent. Because a guiding plate is arranged below the crushing box, and the guiding plate is connected to the sliding mechanism through a connecting rod, and the sliding mechanism is controlled by an electric push rod, the position of the guiding plate can be adjusted, so that the feeding port opened on the guiding plate is located at the second feeding port opened on the feeding pipe, ensuring that the feeding of asphalt concrete will not be stuck or slow.

[0009] As a preferred embodiment of the present invention, the pushing mechanism includes two rotating shafts and a hydraulic cylinder. The two rotating shafts are respectively arranged above the bottom plate and at the bottom of the feeding pipe. The inner cavities of the two rotating shafts are both clamped with movable rods. One end of the movable rod is hinged with a hydraulic cylinder, and the other end of the hydraulic cylinder is fixedly connected to the bottom plate. The installation position and components of the pushing mechanism are determined.

[0010] As a preferred embodiment of the present invention, the crushing mechanism includes a second motor and a crushing roller. The crushing roller is arranged in the inner cavity of the crushing box. The other end of the crushing roller movably penetrates through the inner wall of the crushing box. One end of the crushing roller is movable on the inner wall of the crushing box. The other end of the crushing roller is clamped with a second motor, and the second motor is installed on the side plate. The installation position and components of the crushing mechanism are determined.

[0011] As a preferred embodiment of the present invention, the sliding mechanism includes two sliding grooves and two sliding blocks. The two sliding grooves are respectively opened at the bottom of the crushing box. The two sliding grooves are symmetrical to each other. The inner cavities of the two sliding grooves are slidably installed with sliding blocks. The two sliding blocks are symmetrical to each other. One end of the two sliding blocks away from the sliding grooves is fixedly installed with a connecting rod. The installation position and components of the sliding mechanism are determined.

[0012] As a preferred embodiment of the present utility model, a connecting rod is fixedly installed on the opposite side walls of the two connecting rods, and an electric push rod is fixedly installed at one end of the connecting rod close to the side plate, and the other end of the electric push rod is installed on the side plate. This ensures that the electric push rod can push the connecting rod to move on the sliding mechanism, thereby adjusting the position of the material guiding plate.

[0013] As a preferred embodiment of the present utility model, a material guiding plate is rotatably installed on the opposite side walls at the bottoms of the two connecting rods, a baffle is fixedly installed at one end of the material guiding plate, and a material discharging port is opened on one side of the material guiding plate with respect to the baffle. When the position of the material guiding plate is adjusted, the material discharging port opened on the material guiding plate can be located at the second feeding port opened on the material guiding pipe, ensuring that there will be no jamming or slowdown during the feeding of asphalt concrete.

[0014] The present utility model has the following beneficial effects compared with the prior art:

[0015] In the present utility model, by placing asphalt concrete into the first feeding port and starting the second motor, the stirring mechanism can be driven to crush the asphalt concrete, to a certain extent avoiding the blockage caused by larger asphalt concrete. Since a material guiding plate is provided below the crushing box, and the material guiding plate is connected to the sliding mechanism through a connecting rod, and the sliding mechanism is controlled by an electric push rod, the position of the material guiding plate can be adjusted, so that the material discharging port opened on the material guiding plate can be located at the second feeding port opened on the material guiding pipe, ensuring that there will be no jamming or slowdown during the feeding of asphalt concrete.

Detailed implementation manner

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0024] As Figures 1 to 4 shown, an asphalt concrete feeding machine includes a bottom plate 1, a crushing box 3 and a guide pipe 5. On one side wall above the bottom plate 1, a side plate 2 is installed. Above the bottom plate 1, a pushing mechanism is provided, and the pushing mechanism is used to push the guide pipe 5 to change its angle. Above the bottom plate 1, a crushing box 3 is provided. At the four corners of the bottom of the crushing box 3, support legs 11 are fixedly installed, and the other ends of the four support legs 11 are fixedly connected to the bottom plate 1. Inside the crushing box 3, a crushing mechanism is provided, and the crushing mechanism is used to crush asphalt concrete. Above the crushing box 3, a first feed inlet 4 is provided, and at the bottom, a first discharge outlet 15 is provided. Below the first discharge outlet 15, a guide plate 14 is provided. At the bottom of the crushing box 3, a sliding mechanism is provided, and the sliding mechanism is used to drive the guide plate 14 to move. Above one side of the guide pipe 5 close to the crushing box 3, a second feed inlet 10 is provided. Below the other end of the guide pipe 5, a second discharge outlet 7 is provided, and at the port, a first motor 6 is provided. By placing asphalt concrete through the first feed inlet 4 and starting the second motor 17, the stirring mechanism can be driven to crush the asphalt concrete, to a certain extent avoiding the situation of blockage caused by relatively large asphalt concrete. Since a guide plate 14 is provided below the crushing box 3, and the guide plate 14 is connected to the sliding mechanism through a connecting rod 12, and the sliding mechanism is controlled by an electric push rod 19, the position of the guide plate 14 can be adjusted, so that the discharge opening 23 opened at the guide plate 14 is located at the second feed inlet 10 opened on the guide pipe 5, ensuring that there will be no jamming or slow feeding during the feeding of asphalt concrete.

[0025] In the specific implementation manner, the pushing mechanism includes two rotating shafts 8 and a hydraulic cylinder 9. The two rotating shafts 8 are respectively arranged above the bottom plate 1 and at the bottom of the material guiding pipe 5. The inner cavities of the two rotating shafts 8 are both clamped with movable rods 18. One end of the movable rod 18 is hinged to the hydraulic cylinder 9, and the other end of the hydraulic cylinder 9 is fixedly connected to the bottom plate 1. In this setting, the installation position and components of the pushing mechanism are determined.

[0026] Furthermore, the crushing mechanism includes a second motor 17 and a crushing roller 16. The crushing roller 16 is arranged inside the crushing box 3. The other end of the crushing roller 16 movably penetrates through the inner wall of the crushing box 3. One end of the crushing roller 16 is movable inside the inner wall of the crushing box 3. The other end of the crushing roller 16 is clamped with the second motor 17, and the second motor 17 is installed on the side plate 2. In this setting, the installation position and components of the crushing mechanism are determined.

[0027] Furthermore, the sliding mechanism includes two chutes 20 and two sliders 21. The two chutes 20 are respectively opened at the bottom of the crushing box 3. The two chutes 20 are symmetrical to each other. The inner cavities of the two chutes 20 are slidably installed with sliders 21. The two sliders 21 are symmetrical to each other. One end of the two sliders 21 away from the chutes 20 is fixedly installed with a connecting rod 12. In this setting, the installation position and components of the sliding mechanism are determined.

[0028] Furthermore, a connecting rod 22 is fixedly installed on the opposite side walls of the two connecting rods 12. One end of the connecting rod 22 close to the side plate 2 is fixedly installed with an electric push rod 19, and the other end of the electric push rod 19 is installed on the side plate 2. In this setting, it is ensured that the electric push rod 19 can push the connecting rod 12 to move on the sliding mechanism, so as to adjust the position of the material guiding plate 14.

[0029] Furthermore, a material guiding plate 14 is rotatably installed on the opposite side walls at the bottom of the two connecting rods 12. One end of the material guiding plate 14 is fixedly installed with a baffle 13. A material discharging port 23 is opened on one side of the material guiding plate 14 and the baffle 13. In this setting, when the position of the material guiding plate 14 is adjusted, the material discharging port 23 opened at the material guiding plate 14 can be located at the second feeding port 10 opened on the material guiding pipe 5, ensuring that there will be no jamming or slowdown during the feeding of asphalt concrete.

[0030] The implementation principle of an asphalt concrete feeding machine in this embodiment is as follows: First, put asphalt concrete into the first feeding port 4. Then, by starting the second motor 17, the stirring mechanism can be driven to crush the asphalt concrete, which to a certain extent avoids the blockage caused by large pieces of asphalt concrete. Since a material guiding plate 14 is arranged below the crushing box 3, and the material guiding plate 14 is connected to the sliding mechanism through a connecting rod 12, and the sliding mechanism is controlled by an electric push rod 19, the position of the material guiding plate 14 can be adjusted. Thus, the feeding port 23 opened at the material guiding plate 14 can be located at the second feeding port 10 opened on the material guiding pipe 5. At this time, by starting the first motor 6, the first motor 6 can transport the asphalt concrete entering the material guiding pipe 5, and then feed the material through the second discharging port 7 (because a pushing mechanism is arranged on the bottom plate 1, so that the position of the material guiding pipe 5 can be adjusted).
