Description

Technical Field

[0001] The utility model relates to the technical field of material blocking of pavers, in particular to a material blocking device for pavers. Background Art

[0002] The paver integrates multiple core systems such as the travel system, hydraulic system, and material distribution system, which work together to ensure the smooth progress of the paving work. The working principle of the paver covers multiple key steps from navigation positioning to hopper loading, to paving layer thickness adjustment and mobile paving, and each step is closely linked and indispensable.

[0003] However, in actual applications, there are often some problems with the material blocking structure of the paver. An ideal material blocking structure should be able to accurately control the flow and distribution of materials in the material distribution device to ensure that the material is supplied evenly and stably during the paving process. However, the reality is that due to design or manufacturing deficiencies, existing material blocking structures often find it difficult to achieve this ideal state.

[0004] On the one hand, the retaining structure has limitations in controlling the flow of materials. This may lead to uneven distribution of materials during paving, or even blockage or leakage of materials, which seriously affects the uniformity and continuity of paving. On the other hand, the retaining structure is also incapable of retaining materials in the paving strips. Due to the poor retaining effect, materials are prone to overflow or scatter during paving, which not only affects the flatness, but also may lead to waste of resources. Utility Model Content

[0005] The main purpose of the utility model is to provide a material blocking device for a paver, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A material blocking device for a paving machine comprises a frame, a hopper, a conveying device, a discharging device, a bracket, a side frame, a transmission screen and a material dividing device, wherein the hopper and the conveying device are mounted on the frame, the conveying device is connected to the hopper and realizes material conveying, the bracket is located beside the frame, the discharging device and the material dividing device are mounted on one side of the upper end of the bracket, and are connected to the conveying device through the discharging device, the side frame is mounted on the bracket, the transmission screen is mounted on the side frame through a rotating shaft, and the material dividing device disperses the material on the transmission screen;

[0008] A fixing frame is installed on the two side frames, and a paving strip is provided at the groove at the lower end of the fixing frame.

This design not only realizes the efficient and uniform spreading of materials, but also effectively avoids the occurrence of material accumulation and blockage phenomena, thus greatly improving the construction quality and efficiency.

This not only reduces the waste of materials, but also eliminates the potential safety hazards caused by material overflow, providing a strong guarantee for the safety management of the construction site.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0025] like Figures 1 to 4 As shown, this embodiment provides a material blocking device for a paving machine, which is mainly composed of a frame 1, a hopper 2, a conveying device 3, a discharging device 4, a bracket 5, a side frame 6, a transmission screen 7 and a material dividing device 8. The hopper 2 and the conveying device 3 are firmly mounted on the frame 1, wherein the conveying device 3 is closely connected with the hopper 2 and is responsible for realizing continuous conveying of materials. The bracket 5 is arranged on one side of the frame 1 to provide support for other components.

[0026] On one side of the upper end of the bracket 5, the discharging device 4 and the material distribution device 8 are carefully installed. The discharging device 4 is connected to the conveying device 3 to ensure that the material can smoothly enter the subsequent processing link. The side frame 6 is installed on the bracket 5 to provide a stable installation platform for the transmission screen 7. The transmission screen 7 is installed on the side frame 6 through a rotating shaft and can rotate freely, so that the material is evenly distributed on it.

[0027] The main function of the material distributor 8 is to evenly distribute the material on the transmission screen 7. The material distributor 8 adopts a square tube design, and multiple square tube type material distributors 8 are arranged in a zigzag shape, and a gap 14 is formed between two adjacent square tubes. This design allows the material to be more evenly distributed on the transmission screen 7, thereby improving the paving effect.

[0028] On the side frame 6, a fixing frame 9 is also installed. At the lower groove of the fixing frame 9, a spreading bar 10 is provided, and its cross-section is designed in a "丿" shape, with the lower edge being arc-shaped, which helps to spread the material better. At the upper opening of the fixing frame 9, an adjusting screw 11 connected to the spreading bar 10 is inserted. By rotating the adjusting screw 11, the distance between the spreading bar 10 and the transmission sieve 7 can be conveniently adjusted to meet the requirements of different materials and spreading thicknesses.

[0029] In addition, a baffle 12 is connected to the rod bodies of the two adjusting screws 11. The baffle 12 is designed in an arc shape, which can tightly cover the spreading bar 10 and contact the transmission sieve 7, effectively preventing the material from overflowing during the spreading process. At the same time, the top of the baffle 12 is a square bar, which is fixed to the adjusting screw 11 through nuts and gaskets, so that the distance between the baffle 12 and the transmission sieve 7 can also be adjusted.

[0030] To enhance the stability and safety of the device, both ends of the fixing frame 9 are firmly fixed to the support 5 through bolts, nuts and gaskets, and anti-slip pads are provided at the connection. This design not only improves the stability of the device but also helps to extend the service life of the device. Embodiment

[0031] This embodiment is similar to Embodiment 1. Similarly, a baffle device for a paver is provided, and its main components and functions are basically the same. However, some details have been optimized and improved.

[0032] Specifically, in addition to the square bar at the top of the baffle 12 in this embodiment, a plurality of baffle strips 13 are also connected. These baffle strips 13 are designed in a serrated shape and can be embedded in the notch 14 of the material distributing device 8. This design not only enhances the baffle effect and prevents the material from overflowing from the notch 14 but also can drive the discharging device 4 to vibrate when the baffle 12 contacts and vibrates with the transmission sieve 7, which helps to improve the uniformity and continuity of discharging.

[0033] At the same time, the adjusting screw 11, the baffle 12 and the baffle strips 13 in this embodiment can be adjusted synchronously. By adjusting the relative position of the nut and the adjusting screw 11, the distances between the baffle 12 and the baffle strips 13 and the transmission sieve 7 can be conveniently adjusted simultaneously, so that the device can meet the requirements of different materials and spreading thicknesses and improve the spreading quality and efficiency.

[0034] This embodiment further improves the practicality and flexibility of the baffle device by optimizing the baffle structure and adjustment method, so that it can play a better role during the operation of the paver.

[0035] Paving process: The material to be paved is loaded into the hopper 2. As the part for storing and initially conveying materials, the hopper 2 provides a guarantee for subsequent continuous operation. Then, the conveying device 3 starts to work and continuously conveys the material in the hopper 2 to the discharging device 4. The conveying device 3 ensures that the material can flow stably and continuously to the next link.

[0036] When the material enters the discharging device 4, the material distributor 8 starts to work. Its serrated square tube design allows the material to be evenly distributed on the transmission screen 7. This design avoids material accumulation and blockage, and helps to improve the uniformity of paving. After the material is evenly distributed on the transmission screen 7, the paving strips 10 on the fixed frame 9 start to work. Since the paving strips 10 have a specific shape and design, they can flatten the material to a predetermined paving thickness.

[0037] By rotating the adjusting screw 11, the distance between the paving strip 10 and the driving screen 7 can be conveniently adjusted, thereby achieving adaptation to different materials and paving thicknesses.

[0038] Material blocking process: During the paving process, the material blocking plate 12 plays a key role. Its arc-shaped design can tightly cover the paving strip 10 and contact the transmission screen 7, effectively preventing the material from overflowing from both sides during the paving process.

[0039] In the second embodiment, the blocking strips 13 connected to the top of the blocking plate 12 further enhance the blocking effect. These serrated blocking strips 13 can be embedded in the notches 14 of the material distribution device 8 to further prevent the material from overflowing from the notches 14.

[0040] By adjusting the relative position of the nut and the adjusting screw 11, the distance between the material blocking plate 12 and the material blocking bar 13 and the transmission screen 7 can be conveniently and synchronously adjusted. This synchronous adjustment mechanism enables the device to adapt to the needs of different materials and paving thicknesses, and improves the practicality and flexibility of the material blocking device.

[0041] The paving and material blocking processes of the paver achieve efficient and uniform paving of materials through carefully designed structures and mechanisms, while effectively preventing material overflow during the paving process, thereby improving construction quality and efficiency.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
