Description

Technical Field

[0001] This utility model relates to the technical field of asphalt construction auxiliary tools, specifically an auxiliary tool for manual asphalt paving in municipal road engineering. Background Technology

[0002] With rapid economic development, the construction of urban infrastructure has expanded accordingly, with highway construction being particularly important. Modern urban roads and highways generally use asphalt pavement, which is fast and cost-effective. During road construction, asphalt is laid and compacted to form various types of road surfaces. Asphalt paving is usually done with pavers, but some areas cannot be paved mechanically and must be done manually. Previously, manual paving tools were used. However, existing manual asphalt paving tools are limited in function and cannot switch paving actions according to site conditions. Therefore, there is an urgent need for a new auxiliary tool for manual asphalt paving in municipal road engineering to solve these problems. Utility Model Content

[0003] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an auxiliary tool for manual asphalt paving in municipal road engineering, so as to solve the problem mentioned in the background art that the existing tools used for manual asphalt paving have limited functions and cannot switch paving actions according to the site conditions.

[0004] This utility model provides the following technical solution: an auxiliary tool for manual asphalt paving in municipal road engineering, including a shovel structure, the shovel structure including a first shovel, a second shovel, and a shovel handle, the first shovel being threadedly connected to the second shovel, the second shovel being fixedly connected to the shovel handle, and a shovel head mechanism, the shovel head mechanism including a shovel head, the first shovel being fixedly connected to the shovel head, the shovel head having a pusher plate groove, a pusher plate being rotatably connected in the pusher plate groove, a limit block being fixedly connected to the shovel head, first bolt holes being opened on both sides of the shovel head, first bolt grooves being opened on both sides of the pusher plate, two second bolt holes being opened on the pusher plate, two second bolt grooves being opened on the limit block, and a paving rake groove being opened on the pusher plate, a paving rake being movably connected in the paving rake groove. The paving rake has two third bolt slots. Two paving rakes are fixed to the paving rake groove by bolts. The bolts pass through the first bolt hole and connect to the first bolt slot, fixing the pusher plate in the pusher plate slot. This allows the shovel head to shovel and lift material. When pushing material, the bolt in the first bolt hole is removed, and the pusher plate flips out. A limiting block limits the flipping angle of the pusher plate, making it perpendicular to the shovel head. The angle is fixed by bolts connecting to the second bolt slot, allowing the pusher plate to push material. Removing the bolt in the third bolt slot separates the paving rake from the paving rake groove, allowing the pusher plate to rak material. This allows for switching paving actions according to site conditions. This method is simple in structure, easy to use, and improves the practicality and flexibility of the device.

[0005] Furthermore, an adjusting rod is threaded onto the first shovel bar. The length of the device is adjusted by connecting the adjusting rod to the first and second shovel bars, thereby making it comfortable for construction workers of different heights to use and improving the practicality of the device.

[0006] Furthermore, an anti-slip rubber sleeve is fixedly connected to the second shovel. The anti-slip rubber sleeve increases the friction between the hand and the grip, making it less likely for construction workers to slip out of their hands and making it more comfortable to hold, thus improving the practicality of the device.

[0007] Furthermore, a plug is threaded onto the handle, and the handle is hollow inside, with a screwdriver placed inside. Unscrewing the plug makes it easy to access the screwdriver in the handle, thus improving the ease of use of the device.

[0008] Furthermore, the shovel head is provided with bolt placement slots, and six bolt placement slots are symmetrically arranged. Bolts taken out from the shovel head, push plate and paving rake are placed in the bolt placement slots to prevent loss, which improves the practicality of the device.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. This utility model comprises a shovel head, a pusher plate groove, a pusher plate, a limiting block, a first bolt hole, a first bolt groove, a second bolt hole, a second bolt groove, a paving rake groove, a paving rake, a third bolt groove, and a third bolt. The bolt passes through the first bolt hole and connects with the first bolt groove to fix the pusher plate in the pusher plate groove, thereby using the shovel head to shovel and lift materials. When pushing materials, the bolt in the first bolt hole is removed, and the pusher plate flips out. The limiting block limits the flipping angle of the pusher plate, making the pusher plate perpendicular to the shovel head. The angle is fixed by the bolt connecting with the second bolt groove, allowing the pusher plate to push materials. The bolt in the third bolt is removed, causing the paving rake to separate from the paving rake groove, allowing the pusher plate to rake materials. This allows for switching paving actions according to the site conditions. This method has a simple structure, is easy to use, and improves the practicality and flexibility of the device.

[0011] 2. This utility model features an anti-slip rubber sleeve, which increases friction with the palm of the hand, making it less likely for construction workers to slip out of their hands and providing a comfortable grip, thus improving the practicality of the device.
