[0023] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments, but the present invention is not limited thereto.

[0024] like Figure 1 As shown, the present invention provides an auxiliary tool for laying mortar on the undercover of municipal road sidewalks, including an operating rod 1, a main power system, a driven stirring system and a scraping tooth 12. The lower end of the operating rod 1 is connected to an operating rod connector 2, and the operating rod connector 2 includes a cone and a sleeve. The cone is clamped on the lower end of the operating rod 1, and the sleeve is placed horizontally. Its side wall is fixedly connected to the lower end of the cone. The sleeve is used to connect the main power system to achieve free rotation within the operating surface, which is convenient for operation. Figure 2 shown.

[0025] like Figure 3 As shown, the main power system includes a driving shaft 3, a driving wheel 4, and a main power gear 5. The driving shaft 3 is inserted into the sleeve portion of the operating rod connector 2. A driving wheel 4 and a main power gear 5 are installed at both ends of the driving shaft 3, and the driving wheel 4 on each side is located outside the main power gear 5. In order to travel in dry and hard mortar, the driving wheel 4 adopts an impeller structure, that is, the wheel surface is composed of a plurality of radially arranged fan blades, which ensures that the driving wheel 4 can travel smoothly in the mortar without slipping.

[0026] like Figure 4 As shown, the driven stirring system includes a driven shaft 6, a driven gear 7 and a stirring blade 8. A driven gear 7 is connected to each end of the driven shaft 6. A stirring blade 8 is fixed on the driven shaft 6 between the two driven gears 7. Preferably, the angles of the stirring blades 8 are different and change in a spiral shape. The driven gear 7 is engaged with the main power gear 5 on the same side. The rotation of the main power gear 5 drives the driven gear 7 to rotate, thereby rotating the driven shaft 6 and the stirring blade 8 thereon to play a mixing role. Preferably, the diameter and number of teeth of the driven gear 7 are smaller than the diameter and number of teeth of the main power gear 5, so that the main power gear 5 drives the driven gear 7 to move at a variable speed.

[0027] like Figure 5 As shown, in some preferred embodiments, a dust suppression system is also included, which includes a dust suppression cover 9 and a gear bin 10. The dust suppression cover 9 is sleeved on the outside of the driving shaft 3 and the driven shaft 6, and the rear side of the dust suppression cover 9 is connected to the scraping teeth 12. The two ends of the dust suppression cover 9 are respectively connected to the gear bin 10, and the gear bin 10 covers the outside of the driving power gear 5 and the driven gear 7 to play a dust-proof role and prevent mortar from splashing into the gear and causing it to be unable to rotate.

[0028] like Figure 5 and 6As shown, some more preferred embodiments further include a fixed depth wheel 13 and a stop bolt 15. Vertical stop rings 14 are fixed to each end of the dust suppression hood 9 connected to the scraping teeth 12. The outer wall of the stop ring 14 is provided with a threaded hole for connecting the stop bolts 15. The vertical connecting rod of the fixed depth wheel 13 is inserted into the stop ring 14 and abutted and fixed by the stop bolts 15. The mortar thickness can be adjusted and fixed by adjusting the height of the fixed depth wheel 13 fixed to the stop ring 14. Preferably, a counterweight 11 is provided on the dust suppression hood 9 at the location connected to the scraping teeth 12.

[0029] The preferred embodiment of actual construction: the operating rod 1 is made of a Φ25mm, 1.5m long round wooden pole; the operating rod connector 2 is a 20mm inner diameter bearing installed as a sleeve on the driving shaft 3, and the tapered structure is welded to the bearing. The driving wheel 4 is a trapezoidal steel plate with a wall thickness of 5mm welded to the ring in an annular direction; the driving shaft 3 is a round steel with a diameter of 12mm; the main power gear 5 is a 25-tooth spur gear with an inner diameter of 12mm. The driven gear 7 is a 10-tooth spur gear with an inner diameter of 12mm; the stirring blade 8 is a steel blade with a wall thickness of 5mm, spirally welded to the driven shaft; the driven shaft 6 is a round steel with a diameter of 12mm. The fixed depth wheel 13 is the driven travel wheel. The gear compartment 10 is made of a 3mm thick steel plate cut and fixed with bolts.

[0030] Instructions for use: Before use, manually adjust the height of the fixed depth wheel 13 through the limit bolt 15 to ensure that the thickness of the mortar after scraping is consistent with the design thickness. Then, hold the operating lever 1 and pull it horizontally backward. The driving wheel 4 inserted into the mortar rotates with the horizontal movement of the operating lever 1, driving the main power gear 5 to rotate. The main power gear 5 drives the driven gear 7 to rotate at a variable speed, further driving the mixing blade 8 to rotate, and the dry and hard mortar is evenly mixed; the dust suppression cover 9, under the pressure of the counterweight block 11, controls the mortar at the designed height through the scraping teeth 12, and at the same time, the scraping teeth 12 clean out gravel, garbage, etc.

[0031] The use of a dust suppression hood can avoid air pollution during the cement mixing process. The scraping teeth and the fixed depth wheel are cleverly combined to control the mortar paving thickness; the operation that requires experienced pavers is transformed into that of ordinary workers; this tool can achieve a paving area of 0.5-1 square meters with one pull, greatly reducing labor consumption, improving construction efficiency, and reducing construction costs, with very high economic and social benefits.

[0032] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art may make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered to be within the scope of protection of the present invention.
