Description

Technical Field

[0001] The utility model relates to the field of pavement construction equipment, and particularly relates to a cold-mix and cold-laying pavement mixture spreading device. Background Technique

[0002] Cold-mix and cold-laying pavement mixture is an environmentally friendly and efficient road construction material, which is mainly composed of mineral materials and emulsified asphalt or liquid asphalt. It is an asphalt mixture made by mechanical stirring at normal temperature. In the process of pavement repair, a small hand-held paver is often used for spreading asphalt mixture. When the existing small hand-held paver is feeding asphalt mixture, a wheeled excavator is often used for feeding asphalt mixture. During the feeding process, due to the limitation of the size of the feeding hopper, it is easy to cause leakage of materials outside the feeding hopper during the feeding process of the excavator, and additional construction personnel need to be arranged to collect and handle the leaked materials. Therefore, in order to solve the problem of material spillage during feeding caused by the size limitation of the feeding hopper, a new type of cold-mix and cold-laying pavement mixture spreading device is needed.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides as Figures 1-5A cold-mix and cold-laying pavement mixture spreading device shown in the figure includes a paver 1. A feeding unit 2 is arranged on the side of the paver 1. It also includes a feeding component and an auxiliary component;

[0023] It should be noted that the overall reference model of the paver 1 and the feeding unit 2 is the working principle of the SF2500 walk-behind paver;

[0024] Specifically, the feeding component is arranged on the top of the feeding unit 2. The feeding component includes a feeding hopper 3 arranged on the top of the feeding unit 2. The feeding hopper 3 is used to receive cold-laid asphalt;

[0025] It should be noted that the feeding hopper 3 and the feeding port on the top of the feeding unit 2 are fixed by welding;

[0026] Specifically, the auxiliary component is used for feeding assistance of the feeding hopper 3. The auxiliary component includes baffles 4 symmetrically inserted and connected to the top of the feeding hopper 3. A movable plate 5 is hinged to the bottom of the baffle 4;

[0027] It should be noted that a movable groove for the baffle 4 to penetrate is opened at the top of the feeding hopper 3. A handle 402 is fixedly connected to the top of the baffle 4, and the connection method is welding. A hinge 401 is arranged at the hinge of the baffle 4 and the movable plate 5. The hinge 401 and the sides of the baffle 4 and the movable plate 5 are fixed by screws;

[0028] Limit parts for fixing the movable plate 5 are symmetrically arranged on the sides of the movable plate 5;

[0029] Specifically, the limit part includes sliding blocks 501 arranged on the sides of the movable plate 5. Fixing bolts 502 are inserted through the sides of the sliding blocks 501, and the ends of the fixing bolts 502 are inserted and connected to the sides of the movable plate 5;

[0030] It should be noted that sliding grooves 301 for the sliding blocks 501 to move are opened on the inner wall of the movable groove. The sliding grooves 301 are in a convex shape, so that the sliding blocks 501 can be limited to move up and down in the sliding grooves 301. Column-shaped holes for the fixing bolts 502 to penetrate are opened on the sides of the sliding blocks 501. Threaded holes for the fixing bolts 502 to penetrate are opened on the sides of the movable plate 5. Through the cooperation of the fixing bolts 502 and the threaded holes, the positions of the sliding blocks 501 and the movable plate 5 are fixed;

[0031] Specifically, a compression spring 503 is arranged at the penetration of the fixing bolt 502 and the sliding block 501. The compression spring 503 is in the column-shaped hole. The compression spring 503 is sleeved on the outside of the fixing bolt 502. The compression spring 503 provides a thrust for the fixing bolt 502, making the threaded engagement of the fixing bolt 502 and the threaded hole tighter;

[0032] A positioning part for restricting the turning angle of the baffle 4 is arranged on the side of the feeding hopper 3;

[0033] Specifically, the positioning part includes a fixing block 6 arranged on the side of the feeding hopper 3, and a positioning bolt 7 for supporting the baffle 4 is screwed and inserted through the bottom of the fixing block 6;

[0034] It should be noted that the fixing block 6 is fixedly welded to the side of the feeding hopper 3, and a threaded through hole for the positioning bolt 7 to penetrate is provided on the side of the fixing block 6. The staff rotates the positioning bolt 7 to move the positioning bolt 7 up and down, so as to support and fix the position of the baffle 4 at the flipping angle;

[0035] In the actual use process, an auxiliary component is arranged on the top of the feeding hopper 3. By symmetrically inserting the baffle 4 through the top of the feeding hopper 3 in the auxiliary component, the user pulls out the baffle 4. The pulled-out baffle 4 is hinged to the movable plate 5. Due to the limitation of the sliding block 501 in the positioning part, the movable plate 5 stays in the movable groove. At this time, the hinge joint of the baffle 4 and the movable plate 5 exposes the movable groove, so that the baffle 4 can be flipped. By rotating the positioning bolt 7 and adjusting the height of the positioning bolt 7, the positioning bolt 7 supports and fixes the flipping angle of the flipped baffle 4, so as to facilitate the feeding of the feeding hopper 3. When feeding, the asphalt material spilled on the side of the feeding hopper 3 is blocked, so that it slides obliquely into the feeding hopper 3, avoiding the asphalt from spilling onto the non-operation surface and requiring workers to collect this part of the asphalt material.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
