Description

Technical Field

[0001] The utility model belongs to the field of pavers, and in particular relates to a full-width telescopic screed material guiding device and a pavers. Background Art

[0002] The paver is one of the key equipment for constructing the base and surface layers of various roads, squares, airports, parking lots, dams and ditches. It mainly consists of two parts: the main machine and the ironing device.

[0003] Among them, the structure of the ironing plate in the ironing device mostly adopts a telescopic structure with adjustable paving width, that is, a full-width telescopic ironing plate structure. In order to ensure that the mixed asphalt material of the paver is more uniform and to prevent the asphalt mixture from directly contacting the side baffles and sliding columns set at the telescopic section of the full-width telescopic ironing plate, a material guide device is generally installed between the telescopic section and the extended section of the full-width telescopic ironing plate.

[0004] However, existing material guide devices have certain drawbacks during use, limiting the convenience of paving machines. Specifically, existing material guide devices often utilize a mechanically assembled structure, consisting of two guide plate frames fixed to the side panels of the full-width telescopic screed, and a lifting plate mounted on the two guide plate frames. The horizontal movement of the side panels primarily drives the two guide plate frames toward or away from each other to adjust the width of the entire material guide device. A height adjustment mechanism between the lifting plate and the guide plate frames adjusts the height of the lifting plate to meet the required paving height. This height adjustment mechanism often utilizes a manual adjustment mechanism consisting of a handle and a ball screw. Consequently, existing material guide devices are not only complex and difficult to assemble and disassemble, but also prone to reduced synchronization between the two lifting plates due to the need for manual height adjustment. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a full-width telescopic screed material guiding device and a paver with simple structure, convenient operation and good synchronization, so as to improve the user experience of the paver user.

[0006] To address the aforementioned technical issues, the present invention provides a full-width telescopic screed material guide device, comprising two horizontally symmetrically arranged material guide plates, the sides of which are connected to the side baffles of the full-width telescopic screed, and the material guide plates are capable of vertically sliding relative to the side baffles. Guide rails are provided at the upper ends of the material guide plates, and fixed supports are horizontally mounted on the outer sides of the guide rails for horizontal sliding movement. At least one semi-automatic lifting drive mechanism is provided at the upper end of the fixed support, and all semi-automatic lifting drive mechanisms provided on the same material guide plate are connected to the same synchronous controller. Thus, the material guide plates of the present invention can both move horizontally with the side baffles to achieve overall width changes, and can also be raised and lowered by the semi-automatic lifting drive mechanism to meet changing construction requirements. Moreover, since the utility model connects all the semi-automatic lifting drive mechanisms at the same material guide plate to the same controller, it can control the synchronous lifting and lowering of all the semi-automatic lifting drive mechanisms on a single side through the synchronous controller to ensure that all parts of the material guide plate can be lifted and lowered synchronously, thereby ensuring the synchronization of the material guide plate and the material guiding effect; since the utility model directly slidably mounts the end of the material guide plate on the side baffle, the utility model can also simplify the structure of the entire material guiding device and simplify the corresponding disassembly and assembly steps.

[0007] Furthermore, a vertical slot is formed on the surface of the side baffle, and a connecting plate is provided on the side of the guide plate near the corresponding side baffle. The connecting plate has a mounting hole. One end of a bolt is passed through the vertical slot and the mounting hole in sequence, and then threadedly connected to a fixing nut. A gap can exist between the fixing nut and the connecting plate; or one end of a bolt is passed through the mounting hole and the vertical slot in sequence, and then threadedly connected to a fixing nut. A gap can exist between the fixing nut and the side baffle. In this way, the connection between the guide plate and the side baffle is achieved through the cooperation between the connecting piece and the fixing nut, ensuring that the guide plate can move horizontally with the side baffle; and the cooperation between the connecting piece and the fixing nut and the vertical slot enables relative vertical movement between the guide plate and the side baffle. The specific size of the gap only needs to meet the vertical freedom of the guide plate.

[0008] Furthermore, a T-slot is provided on the surface of the side baffle, and a T-slider is provided on the side of the guide plate close to the corresponding side baffle. The T-slider is vertically slidably connected to the T-slot, so that it can ensure that the guide plate can move horizontally with the side baffle through the cooperation between the groove wall of the T-slot and the side wall of the T-slider, and can also ensure the relative movement of the guide plate and the side baffle in the vertical direction through the vertical sliding of the T-slider and the T-slot.

[0009] Furthermore, the semi-automatic lifting drive mechanism includes a first electric push rod, which is electrically connected to a synchronous controller. A mounting base is fixedly mounted on the fixed end of the first electric push rod, which is mounted on the base section of the fully telescopic screed. A connector is mounted on the telescopic end of the first electric push rod, which is connected to a fixed support member via a fastener. In this way, the synchronous controller can control the extension and retraction of the corresponding first electric push rod, thereby controlling the lifting and lowering of the corresponding guide plate.

[0010] Furthermore, the connecting member includes a guide slide, one end of which is connected to the telescopic end of the electric push rod, and the other end of which is connected to the fixed support frame. A guide sleeve is provided in the middle of the guide slide, and the guide sleeve is fixedly mounted on the lower part of the mounting base. In this way, the cooperation between the guide slide and the guide sleeve ensures that the guide slide and the guide plate can be raised and lowered smoothly and unobstructed.

[0011] Furthermore, a semi-automatic lifting drive mechanism 2 is provided on one end of the material guide plate close to the corresponding side baffle. The semi-automatic lifting drive mechanism 2 is connected to the corresponding synchronous controller and can be lifted and lowered synchronously with the corresponding semi-automatic lifting drive mechanism 1 under the action of the synchronous controller.

[0012] Furthermore, the structure of the second semi-automatic lifting drive mechanism is the same as that of the first semi-automatic lifting drive mechanism, and it is directly installed on the end of the material guide plate.

[0013] Furthermore, an opening slot facing downward is provided at the lower end of the fixed support member, the slot width of the opening slot is smaller than the slot width at the middle position of the opening slot, the guide rail is horizontally slidably installed in the opening slot, and can slide smoothly with the side baffle.

[0014] On the other hand, the utility model provides a paver, which includes the above-mentioned full-width telescopic screed material guiding device, and prevents the accumulation of paving materials through the above-mentioned full-width telescopic screed material guiding device, thereby ensuring the normal operation of the full-width telescopic screed.

[0015] It can be seen from the above technical solution that the utility model has the following advantages: the material guide plate in the utility model can not only move horizontally with the side baffle to realize the overall width change, but also can be lifted and lowered under the action of the semi-automatic lifting drive mechanism 1 to meet the construction change requirements; and since the utility model controls all the semi-automatic lifting drive mechanisms 1 and the semi-automatic lifting drive mechanism 2 at the same material guide plate by the same controller, it can control all the semi-automatic lifting drive mechanisms on a single side to lift and lower synchronously through the synchronous controller to ensure that all parts of the material guide plate can lift and lower synchronously, thereby ensuring the synchronization of the material guide plate and the material guiding effect; since the utility model directly slidably mounts the end of the material guide plate on the side baffle, the utility model can also simplify the structure of the entire material guiding device and simplify the corresponding disassembly and assembly steps.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, the utility model provides a full-width telescopic screed material guide device, which includes two horizontally symmetrically arranged material guide plates 3, the side surfaces of the two material guide plates 3 are connected to the side baffles 6 on both sides of the full-width telescopic screed, and the material guide plates 3 can slide vertically relative to the side baffles 6.

[0024] Specifically in this embodiment, the structure between the guide plate 3 and the side baffle 6 can adopt any one of the following two structures: the first is to open a vertical long hole on the surface of the side baffle 6, and set a connecting plate on the side of the guide plate 3 close to the corresponding side baffle 6, and the connecting plate is provided with a mounting hole, and one end of the bolt passes through the vertical long hole and the mounting hole in turn and is threadedly connected with a fixing nut, and a gap can exist between the fixing nut and the connecting plate; or one end of the bolt passes through the mounting hole and the vertical long hole in turn and is threadedly connected with a fixing nut, and a gap can exist between the fixing nut and the side baffle 6; in this way, the connection between the guide plate 3 and the side baffle 6 can be achieved through the cooperation between the connecting piece and the fixing nut, ensuring that the guide The plate 3 can move horizontally with the side baffle 6; it can also achieve relative vertical movement between the guide plate 3 and the side baffle 6 through its cooperation with the vertical long hole. The specific size of the gap only needs to meet the vertical freedom of the guide plate 3 and does not need to be too large. The second method is to provide a T-slot on the surface of the side baffle 6, and provide a T-sliding block on the side of the guide plate 3 close to the corresponding side baffle 6. The T-sliding block is vertically slidably connected to the T-slot. In this way, the groove wall of the T-slot and the side wall of the T-sliding block can ensure that the guide plate 3 can move horizontally with the side baffle 6, and the vertical sliding of the T-sliding block and the T-slot can ensure relative vertical movement between the guide plate 3 and the side baffle 6. In addition to the above two structures, other conventional vertical sliding connection structures on the market can also be used to achieve the connection between the guide plate 3 and the side baffle 6.

[0025] A semi-automatic lifting drive mechanism 2 5 is provided at one end of the guide plate 3, near the corresponding side baffle 6, for driving the guide plate 3 to rise and fall relative to the side baffle 6 of the full-width telescopic screed.

The upper end of the fixed support member 8 is provided with at least one semi-automatic lifting drive mechanism 1 for driving the fixed support member 8 to rise and fall relative to the base section 7 of the full-width telescopic screed. The structure of the semi-automatic lifting drive mechanism 1 is identical to that of the semi-automatic lifting drive mechanism 2 5, and all semi-automatic lifting drive mechanisms 1 and 2 5 provided on the same guide plate 3 are connected to the same synchronous controller. In this way, the synchronous controller can be used to control the synchronous lifting of all semi-automatic lifting drive mechanisms on a single side, ensuring that various parts of the guide plate 3 can rise and fall synchronously, thereby ensuring the synchronization of the guide plate 3 and the material guiding effect. Since the end of the guide plate 3 is directly slidably mounted on the side baffle 6, the utility model can also simplify the structure of the entire material guide device and simplify the corresponding disassembly and assembly steps.

[0026] Specifically, if Figure 2 、 Figure 3As shown, the semi-automatic lifting drive mechanism includes an electric push rod 1, which is electrically connected to a synchronous controller, and a mounting seat 4 is fixedly installed on the fixed end of the electric push rod 1, and the mounting seat 4 is installed on the base section 7 of the full-width telescopic ironing plate; the telescopic end of the electric push rod 1 is installed with a connecting piece, and the connecting piece includes a guide slide 9, and the middle part of the guide slide 9 is provided with a guide sleeve 10, and the guide sleeve 10 is fixedly installed on the lower part of the mounting seat 4, the upper end of the guide slide 9 is connected to the telescopic end of the electric push rod 1, and the lower end of the guide slide 9 is connected to the fixed support frame, and the lower end of the fixed support member 8 is provided with an opening groove facing downward, the groove width of the opening groove is smaller than the groove width at the middle position of the opening groove, and the cross-section of the opening groove is preferably set to C-shaped, and the guide rail 2 is horizontally slidably installed in the opening groove and can slide smoothly with the side baffle 6.

[0027] In this way, when using the utility model for paving operations, the material guide plate 3 in the utility model can move horizontally with the side baffle 6 to achieve overall width changes; it can also be stably lifted and lowered under the joint action of the semi-automatic lifting drive mechanism 1 and the semi-automatic lifting drive mechanism 2 5 to meet the changing needs of construction.
