Description

Technical Field

[0001] This utility model relates to the field of compaction machine technology, and in particular to a compaction machine for overlaying new asphalt concrete on old asphalt pavement. Background Technology

[0002] Asphalt concrete is a mixture made by mixing crushed stone with a certain proportion of road asphalt material under strictly controlled conditions, and it can be used to construct roads. Generally, asphalt concrete needs to be compacted after pouring.

[0003] Because asphalt concrete has a certain degree of viscosity, some material will adhere to the surface of the rollers during the rolling process in the compactor, resulting in material loss and uneven road surface compaction. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that, due to the viscosity of asphalt concrete, some material adheres to the surface of the roller during the rolling process of the roller in the compactor, resulting in material loss and uneven road surface compaction. Therefore, a compactor for overlaying new asphalt concrete on old asphalt pavement is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: a compactor for overlaying new asphalt concrete on old asphalt pavement, comprising an outer frame, a roller disposed inside the outer frame, and horizontal plates disposed on both sides of the outer frame. Threaded rods are threaded through both sides of the front of the two horizontal plates, and a stop plate is rotatably connected to one end of the threaded rod. An A vertical plate is disposed on both sides of the back of one horizontal plate, and a B vertical plate is disposed on both sides of the back of the other horizontal plate.

[0006] The adjustment assembly includes a motor installed on one side of one of the A-plates. The output end of the motor is connected to a lead screw, the other end of which passes through one side of one of the A-plates and is rotatably connected to one side of the other A-plate. Both sides of the lead screw are threaded with transverse shells, and guide rods pass through the other side of the two transverse shells. The two ends of the guide rods are respectively connected to one side of the two B-plates. A cleaning mechanism is provided inside the two transverse shells.

[0007] As a further description of the above technical solution: the cleaning mechanism includes through rods that pass through both sides of the back of the two transverse shells, with a scraper fixedly connected to the other end of the through rods, and a spring sleeved on the surface of the through rods.

[0008] As a further description of the above technical solution: one side of each of the two scrapers is conical, and one side of each of the two scrapers is in contact with both sides of the roller surface.

[0009] As a further description of the above technical solution: a shielding frame is provided on the upper surface of the outer shell frame, and a connector is provided on the front side of the outer shell frame.

[0010] As a further description of the above technical solution: the other side of the abutment is in close contact with the surface of the outer shell frame.

[0011] As a further description of the above technical solution: the two sides of the roller are rotatably connected to the two sides of the inner wall of the outer casing frame, and the roller is located in the middle of the outer casing frame.

[0012] As a further description of the above technical solution: the front of the two horizontal shells is provided with a storage groove, and the scraper is located inside the storage groove.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] With the screw rod, abutment plate, adjustment components, and cleaning components in place, the motor drives the screw rod to rotate during use. The rotation of the screw rod causes the horizontal shells on both sides to move laterally. As the horizontal shells move, they also move the scrapers. One side of the scrapers contacts the surface of the roller, thus scraping off the asphalt concrete adhering to the surface of the roller as the roller rotates, thereby improving the compaction and smoothness of the asphalt concrete surface. At the same time, rotating the screw rod causes the abutment plate to move. The abutment plates on both sides move to abut against or away from the outer frame, thereby allowing the device to be installed and disassembled, facilitating the maintenance and replacement of the cleaning equipment.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 The compactor for overlaying new asphalt concrete on old asphalt pavement provided in this embodiment includes an outer frame 1, a roller 2 is provided inside the outer frame 1, and a horizontal plate 3 is provided on both sides of the outer frame 1. Threaded rods 4 are threaded through both sides of the front of the two horizontal plates 3. One end of the threaded rod 4 is rotatably connected to a stop plate 5. An A vertical plate is provided on both sides of the back of one of the horizontal plates 3, and a B vertical plate is provided on both sides of the back of the other horizontal plate 3.

[0023] The adjustment assembly 6 includes a motor 601 installed on one side of one of the A-plates. The output end of the motor 601 is connected to a lead screw 602. The other end of the lead screw 602 passes through one side of one of the A-plates and is rotatably connected to one side of the other A-plate. Both sides of the surface of the lead screw 602 are threaded with a horizontal shell 603. The other side of the two horizontal shells 603 is provided with a guide rod 604. The two ends of the guide rod 604 are respectively connected to one side of the two B-plates. A cleaning mechanism 8 is provided inside the two horizontal shells 603.

[0024] The motor 601 drives the lead screw 602 to rotate, and the rotation of the lead screw 602 causes the horizontal shells 603 on both sides to move horizontally. When the horizontal shells 603 on both sides move, they drive the scraper 802 to move. One side of the scraper 802 on both sides contacts the surface of the roller 2, and then scrapes off the asphalt concrete adhering to the surface of the roller 2 when the roller 2 rotates. At the same time, the scraper 802 on both sides moves horizontally relative to each other, which facilitates the cleaning of asphalt concrete adhering to the surface of rollers 2 with different diameters.

[0025] Specifically, such as Figure 2 and Figure 4 As shown, the cleaning mechanism 8 includes through rods 801 that pass through both sides of the back of two transverse shells 603. The other end of the through rods 801 is fixedly connected to a scraper 802, and a spring 803 is sleeved on the surface of the through rods 801.

[0026] The spring 803, under its elastic force, allows the scraper 802 to adhere tightly to the surface of the roller 2, resulting in a better scraping effect.

[0027] Specifically, such as Figure 4 As shown, one side of the two scrapers 802 is conical, and one side of the two scrapers 802 is in contact with both sides of the surface of the roller 2.

[0028] The conical scraper 802 is capable of cleaning the asphalt concrete adhering to the surface of the roller 2.

[0029] Specifically, such as Figure 1 As shown, a shielding frame 7 is provided on the upper surface of the outer casing frame 1, and a connector 9 is provided on the front side of the outer casing frame 1.

[0030] The outer frame 1 is connected to the external vehicle body via the connector 9.

[0031] Specifically, such as Figure 1 As shown, the other side of the abutment 5 is in close contact with the surface of the outer casing frame 1.

[0032] Specifically, such as Figure 1 As shown, the two sides of the roller 2 are rotatably connected to the two sides of the inner wall of the outer casing frame 1, and the roller 2 is located in the middle of the outer casing frame 1.

[0033] Specifically, such as Figure 4 As shown, the front of the two horizontal shells 603 has a storage groove, and the scraper 802 is located inside the storage groove.

[0034] The scraper 802 can retract and move in the storage groove under the action of the spring 803, which makes it convenient to adjust the position of the scraper 802.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
