Technical Field

[0001] This invention relates to a rotating device for a paver screed attachment, belonging to the field of road construction machinery technology. Background Technology

[0002] The screed is a core component of the paver and is also the part that paver users care about most. During the use and installation of the screed, a large number of accessories need to be installed, and the installation and adjustment of accessories are time-consuming and labor-intensive. Especially when the paver is moved to another location, a lot of material sticks to the accessories, which needs to be cleaned manually and then disassembled. This inevitably consumes time and labor, increases auxiliary time, and leads to increased user dissatisfaction. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a rotating device for the screed attachment of a paver. The present invention installs a heating device on the side baffle of the attachment, which can heat the asphalt at the end during construction, avoiding the situation where the asphalt at the end solidifies and sticks due to rapid heat dissipation. This can effectively improve the practicality and convenience of the product, increase productivity, and save labor and energy consumption.

[0004] To achieve the above objectives, the present invention provides a rotating device for a paver screed attachment, comprising a pair of rotating devices, each rotating device including a hinged connecting plate and a side baffle, the connecting plate being used to connect the screed.

[0005] A heating device is provided on the side baffle;

[0006] The heating device includes a heating rod, a pressure plate, a welding block with threaded holes, and a clamping bolt;

[0007] The threaded welding block is installed on the side baffle. The heating rod is inserted into the threaded welding block. The pressure plate is attached to the heating rod. The clamping bolt is threaded into the threaded welding block. The clamping bolt abuts against the pressure plate, and the pressure plate presses the heating rod firmly onto the side baffle.

[0008] Furthermore, it also includes a cover plate detachably connected to the side baffle for encapsulating and protecting the heating device.

[0009] Furthermore, a connecting mechanism is provided between the two rotating devices. The connecting mechanism includes a fixing plate and a fixing pin. The fixing plate is rotatably connected to one of the rotating devices, and the fixing pin is fixedly connected to the other rotating device. The fixing plate has a notch for engaging the fixing pin.

[0010] Furthermore,

[0011] The fixing pin includes a first lifting ring, which is threadedly connected to a rotating device.

[0012] The rotating device is threadedly connected to a second lifting ring, the screw of which passes through a fixed plate. The fixed plate is rotatably connected to the screw of the second lifting ring, thereby achieving a rotatable connection between the fixed plate and the rotating device.

[0013] Furthermore, both the fixing plate and the fixing pin are located on the upper part of the side baffle.

[0014] Furthermore, the cover plate is connected to the side baffle by connecting bolts.

[0015] Furthermore, both the connecting plate and the side baffle are provided with rotating tubes, and the rotating tubes of the connecting plate and the side baffle are staggered, with each rotating tube being coaxially arranged;

[0016] A rotating pin is provided in the rotating tube to connect the rotating tube of the connecting plate and the rotating tube of the side baffle, so as to realize the hinge connection between the connecting plate and the side baffle.

[0017] Furthermore, a cotter pin is inserted through the exposed end of the rotating pin after it is inserted into the rotating tube to fix the rotating pin.

[0018] The beneficial effects achieved by this invention are as follows:

[0019] This invention provides a rotating device for the screed attachment of a paver. The invention features a heating device on the side baffle, which heats the asphalt at the end during construction, preventing the asphalt from solidifying and sticking after cooling. This keeps the asphalt in a high-temperature and gentle state, facilitating cleaning by workers, effectively improving the practicality and convenience of the product, increasing productivity, and saving labor and energy consumption.

[0020] The present invention fixes the heating rod by a welding block with threaded holes and sets a pressure plate on the heating rod, which can effectively ensure that the heating rod does not come into contact with the clamping bolt and that the heating rod is not damaged by the clamping bolt.

[0021] This invention uses a clamping bolt to press a pressure plate, which then presses the heating rod firmly onto the side baffle. This ensures that the heating surface of the heating rod is in direct, face-to-face contact with the side baffle without any gaps, effectively improving heat conduction efficiency and heating efficiency for asphalt.

[0027] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0028] Embodiments of the present invention provide a rotating device for an attachment to a paver screed, such as... Figures 1 to 4 As shown, the invention includes two rotating devices arranged in pairs. Each rotating device includes a hinged connecting plate 13 and a side baffle 4. A heating device is mounted on the side baffle 4. The connecting plate 13 is used to connect an ironing board. The heating device includes a heating rod 5, a pressure plate 10, a welded block 11 with a threaded hole, and a clamping bolt 12. The welded block 11 with the threaded hole is mounted on the baffle. The heating rod 5 is inserted into the welded block 11 with the threaded hole. The pressure plate 10 is attached to the heating rod 5. The clamping bolt 12 is threaded into the welded block 11 with the threaded hole and abuts against the pressure plate 10, thereby pressing the heating rod 5 onto the side baffle 4. This invention, by mounting a heating device on the side baffle 4, can heat the asphalt at the end during construction, preventing the asphalt from solidifying and sticking after cooling. This keeps the asphalt in a high-temperature, gentle state, facilitating cleaning by workers, effectively improving the practicality and convenience of the product, increasing productivity, and saving labor and energy consumption.

[0029] In specific settings, such as Figure 1 and Figure 4 As shown, one end of the connecting plate 13 is used to fix the end face of the outermost extended section of the ironing board by bolts, and the other end is hinged to the side baffle 4. During operation, the side baffle 4 is rotated and unfolded through the hinge point. After the operation is completed, the side baffle 4 is also rotated and retracted through the hinge point. To facilitate the fixing and retraction of the two rotating devices, as follows... Figure 1 , Figure 2 and Figure 4As shown, the present invention provides a connecting mechanism between two rotating devices, including a fixing plate 9 and a fixing pin. The fixing plate 9 and the fixing pin are respectively disposed on the two rotating devices. For easy fixing, the fixing plate 9 and the fixing pin are connected by a rotational snap-fit ​​method. To achieve the above connection method, the fixing plate 9 is rotatably disposed on the rotating device. At the same time, a notch is opened on the fixing plate 9. During the rotation of the fixing plate 9, the notch snaps into the fixing pin, thereby realizing the rotational snap-fit ​​between the fixing plate 9 and the fixing pin.

[0030] When connecting the fixing plate 9 to the rotating device, when selecting the fixing pin, such as Figure 1 , Figure 2 and Figure 4 As shown, to facilitate lifting of this device, the fixing pin includes a first lifting ring 8, which is threadedly connected to the rotating device; a second lifting ring 14 is threadedly connected to the rotating device, and the screw of the second lifting ring 14 passes through the fixing plate 9. The fixing plate 9 is rotatably connected to the screw of the second lifting ring 14, thereby realizing the rotatable connection between the fixing plate 9 and the rotating device.

[0031] Meanwhile, to facilitate the operation of the fixing plate 9, the fixing plate 9 and the fixing pin are set on the upper part of the baffle.

[0032] When installing the heating device, since the asphalt mainly adheres to the lower end during operation, the heating device is placed at the lower end of the side baffle 4. Specifically, the installation method is as follows: Figure 1 and Figure 3 As shown, firstly, several welded blocks 11 with threaded holes are welded to the lower part of the side baffle 4 to fix the heating rod 5 and the pressure plate 10. Then, the heating rod 5 is inserted into the welded blocks 11 with threaded holes, and the pressure plate 10 is attached to the heating rod 5. Then, the clamping bolt 12 is screwed into the welded blocks 11 with threaded holes. The top of the clamping bolt 12 abuts against the pressure plate 10, pressing the heating rod 5 onto the side baffle 4. While the pressure plate 10 protects the heating rod 5 from being squeezed by the clamping bolt 12, it makes the entire surface of the heating rod 5 in face-to-face contact with the side baffle 4 without gaps, thereby improving the heat conduction efficiency.

[0033] To protect components of the heating device, such as the pressure plate 10 and heating rod 5, from external materials such as asphalt, such as Figure 1 and Figure 3 As shown, the present invention also provides a cover plate 6 in the heating device. The cover plate 6 is located on the outside of the heating rod 5 and encapsulates the heating rod 5, the pressure plate 10, the welding plate with threaded holes and the clamping bolts 12. During encapsulation, the cover plate 6 is connected to the side baffle 4 by connecting bolts 7.

[0034] To achieve the hinge connection between the connecting plate 13 and the side baffle 4, such as Figure 1 , Figure 2 and Figure 4As shown, at the connection between the connecting plate 13 and the side baffle 4, both the connecting plate 13 and the side baffle 4 are provided with rotating tubes 2. The rotating tubes 2 of the connecting plate 13 and the rotating tubes 2 of the side baffle 4 are staggered to facilitate the coaxial connection of each rotating tube 2. After the rotating tubes 2 are coaxially connected, a rotating pin 1 is inserted in the rotating tube 2 to connect the rotating tubes 2 of the connecting plate 13 and the rotating tubes 2 of the side baffle 4, thereby realizing the hinge connection between the connecting plate 13 and the side baffle 4.

[0035] Meanwhile, to fix the rotating pin 1, a cotter pin 3 is inserted through the exposed end of the rotating pin after it is inserted into the rotating tube 2.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
