[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 A hand-push emulsified asphalt spreader comprises a base 1, an insulation box 3, a centrifugal pump and a spraying pipe 5. A support frame 4 is fixedly connected to the base 1. Two mounting cavities 13 are provided on the support frame 4. A triangular block 12 with a right-angled triangular cross section is slidably connected in each mounting cavity 13. A rotating cylinder 11 is rotatably provided on one side surface of the triangular block 12. A circular hole for moving the rotating cylinder 11 is provided on one side inner wall of the mounting cavity 13. A pressing roller 8 is provided between the two rotating cylinders 11. Rectangular blocks 14 are fixedly connected to both side end surfaces of the pressing roller 8. A rectangular groove for connecting the rectangular block 14 is provided on the surface of each rotating cylinder 11. An extrusion assembly is provided on the support frame 4. The extrusion assembly comprises an extrusion rod 6 slidably provided on the support frame 4. The cross section of the extrusion rod 6 is concave in shape. The inclined surface of each triangular block 12 fits the end surface of the extrusion rod 6.

[0024] A slide groove is provided on the lower inner wall of each mounting cavity 13, in which a slider 15 is slidably connected. The slider 15 is fixedly connected to the triangular block 12. A spring 16 is fixedly connected to the inner wall of one side of the slide groove. The spring 16 is fixedly connected to the slider 15. The slider 15 can limit the moving trajectory of the triangular block 12. During the movement of the triangular block 12, the slider 15 will be driven to slide in the slide groove, and the spring 16 will deform at the same time. Two ear plates are fixedly connected to the extrusion rod 6, and each ear plate is connected to the support frame 4 by a bolt 10. After one end of each bolt 10 is passed through the ear plate and threadedly connected to the support frame 4, the extrusion rod 6 can be prevented from sliding relative to the support frame 4 under the limiting effect of the bolt 10.

[0025] A placement groove is provided on the upper surface of the base 1, and a scraper strip 9 is installed in the placement groove. The scraper strip 9 placed in the placement groove is taken out, and the scraper strip 9 is used to conveniently scrape off the debris remaining on the surface of the pressure roller 8, so as to facilitate the subsequent normal use of the pressure roller 8. A support block 7 is fixedly connected to the support frame 4, and an opening for connecting the spray pipe 5 is provided on the support block 7. One end of the spray pipe 5 passes through the opening on the support block 7. The support block 7 has a certain supporting effect on the spray pipe 5, which is beneficial to improve the stability of the spray pipe 5 when it moves with the base 1.

[0026] A push handle 2 is fixedly connected to the base 1, and a rubber sleeve is fixedly connected to the push handle 2. The push handle 2 is used to facilitate pushing the base 1 to move, and the rubber sleeve made of rubber material can improve the comfort when holding the push handle 2.

[0027] In the present invention, when in use, the pressing roller 8 is first placed between the two rotating cylinders 11, and the rectangular blocks 14 at both ends of the pressing roller 8 face the corresponding rectangular grooves respectively. At this time, there is a small distance between each rectangular block 14 and the rotating cylinder 11. Then, the extrusion rod 6 is pressed downward. During the process of the extrusion rod 6 moving vertically downward, the two ends of the extrusion rod 6 will respectively move downward against the inclined surfaces of each triangular block 12. The two triangular blocks 12 slide in the corresponding installation cavities 13 respectively, and the distance between the two triangular blocks 12 is reduced. During the process of the two rotating cylinders 11 moving closer to each other, each One end of each rectangular block 14 will extend into the corresponding rectangular groove until the end face of each rectangular block 14 is in close contact with the inner wall of the rectangular groove, so that the pressure roller 8 can be stably installed between the two rotating cylinders 11, and then one end of each bolt 10 is passed through the ear plate and threadedly connected to the support frame 4. The two rectangular blocks 14 and the rotating cylinder 11 are stably connected together. In the subsequent process of pushing the base 1, the spray pipe 5 first spreads the asphalt liquid on the road surface, and then when the pressure roller 8 moves, the laid asphalt can be compacted. The operation is very convenient and fast, saving time and effort.

[0028] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.
