DETAILED DESCRIPTION

[0016] 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 implementation methods, but the present invention is not limited thereto.

[0017] like Figure 1 As shown, the present invention provides an auxiliary tool for laying mortar on the sidewalk of a municipal road, 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 connecting piece 2. The operating rod connecting piece 2 includes a cone and a sleeve. The cone is inserted into the lower end of the operating rod 1. The sleeve is placed horizontally, and its side wall is fixedly connected to the lower end of the cone. The sleeve is used to connect the main power system to realize free rotation within the operating surface, which is convenient for operation. Figure 2 shown.

[0018] 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 sleeved in 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 a fan wheel structure, that is, the wheel surface is composed of a number of radially arranged fan blades, which ensures that the driving wheel 4 travels smoothly in the mortar without slipping.

[0019] 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 stirring blades 8 have different angles and change in a spiral shape. The driven gear 7 is meshed with the main power gear 5 on the same side. The driven gear 7 is driven to rotate by the rotation of the main power gear 5, 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 change speed.

[0020] like Figure 5 As shown, in some preferred embodiments, a dust suppression system is also included, which includes a dust suppression hood 9 and a gear bin 10. The dust suppression hood 9 is sleeved on the outside of the driving shaft 3 and the driven shaft 6, and the rear side of the dust suppression hood 9 is connected to the scraping teeth 12. The two ends of the dust suppression hood 9 are respectively connected to the gear bin 10. 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 gears and causing them to be unable to rotate.

[0021] like Figure 5 and 6As shown, in some more preferred embodiments, a fixed depth wheel 13 and a limiting bolt 15 are also included, and limiting rings 14 in the vertical direction are respectively fixed at both ends of the dust suppression cover 9 connected to the scraping teeth 12, and threaded holes are provided on the outer wall of the limiting ring 14 for connecting the limiting bolts 15. The vertical connecting rod of the fixed depth wheel 13 is inserted into the limiting ring 14 and abutted and fixed by the limiting bolts 15. The thickness of the mortar can be adjusted by adjusting the height of the fixed depth wheel 13 fixed in the limiting ring 14. Preferably, a counterweight 11 is provided on the cover body of the dust suppression cover 9 at the connection position with the scraping teeth 12.

[0022] The preferred embodiment of actual construction: the operating rod 1 is a Φ25mm, 1.5m long round wood rod; the operating rod connector 2 is a 20mm inner diameter bearing installed on the driving shaft 3 as a sleeve part, and the cone structure is welded to the bearing. The driving wheel 4 is a 5mm thick trapezoidal steel plate circumferentially welded to the ring; the driving shaft 3 is a 12mm diameter round steel; 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 5mm thick steel blade, spirally welded to the driven shaft; the driven shaft 6 is a 12mm diameter round steel. The fixed depth wheel 13 is a driven walking wheel. The gear bin 10 is made of a 3mm thick steel plate cut and fixed with bolts.

[0023] How to use: Before use, manually adjust the height of the fixed depth wheel 13 through the limit bolt 15 to make the thickness of the mortar after scraping consistent with the design thickness. Then hold the operating lever 1 and pull it back horizontally. 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, and 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 hard mortar is evenly mixed; the dust suppression cover 9 controls the mortar at the designed height through the scraping teeth 12 under the pressure of the counterweight block 11, and the scraping teeth 12 clean out gravel, garbage, etc.

[0024] The use of a dust suppression hood can prevent air pollution during cement mixing, and the skiving teeth and the fixed depth wheel are cleverly combined to control the mortar paving thickness; the operation that requires experienced pavers can be 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.

[0025] Finally, it should be noted that the above are only preferred embodiments of the present invention. Of course, those skilled in the art can 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 equivalent technologies, they should be considered to be within the scope of protection of the present invention.
