As shown in fig. 1 to 5, in this embodiment, on the basis of embodiment 1, two guide holes 22 penetrating through the adjusting cavity 30 are formed in the base 9, two guide posts 5 are vertically arranged on the support frame 1, the guide posts 5 movably penetrate through the guide holes 22, guide grooves 6 having the same length as the guide posts 5 are formed in the side walls of the guide posts 5, the transverse section of each guide groove 6 is T-shaped, and guide blocks matched with the guide grooves 6 are fixed in the adjusting cavity 30. The two guide posts 5 can increase the stability of the movement of the base 9 on the support frame 1, and prevent the base 9 from generating left and right swing amplitude when moving, so as to ensure the effect of coating mortar on the wall surface.
Preferably, a plurality of universal wheels 10 are arranged at the bottom of the support frame 1, so that the moving flexibility of the support frame 1 can be improved, and convenience is brought to constructors to transfer construction points.
Example 4
As shown in fig. 1 to 5, in this embodiment, on the basis of embodiment 1, two clamping plates 15 are respectively disposed on two side walls of the plastering box 7, one end portion of each clamping plate 15 is flush with the plastering surface of the plastering box 7, the side edges of the two clamping plates 15 are hinged to each other to form a V-shaped recycling cavity, a corrugated plate 16 is disposed on the other end portion of each clamping plate 15, and the end portion of the V-shaped recycling cavity is closed by the corrugated plate 16. When the plastering box 7 is contacted with the wall surface, part of mortar can overflow from the two ends of the discharge port 11 and cannot act on the wall surface, for this reason, the applicant arranges two clamping plates 15 at the two sides of the plastering box 7, the two clamping plates 15 are mutually hinged to form a V-shaped recovery cavity, one end of the recovery cavity is flush with the plastering surface of the plastering box 7, the other end of the recovery cavity is sealed by a corrugated plate 16, when in use, the mortar overflowing from the two ends of the discharge port 11 can move into the recovery cavity by mutual extrusion, and constructors can regularly arrange the recovery cavity so as to facilitate the reuse of the recovered mortar; and because buckled plate 16 can produce certain deformation for the volume of retrieving the chamber is variable, when the mortar volume of retrieving increases promptly, retrieves the function in chamber and can not become invalid, especially when plastering the operation to the wall of corner, one of them retrieves the chamber and can fold into the contact with another wall after the flat board through the extrusion, and remaining recovery chamber then normally carries out its recovery function, avoids leaving too big clearance between two adjacent walls, avoids the manual work to carry out the secondary and mends grey operation.
Wherein, an organ cover 27 is fixed on two opposite side walls of the plastering box 7 respectively, and the organ cover 27 is connected with the side wall of the kick-out plate 13 back to the discharge hole 11. Organ covers 27 are fixed on two opposite side walls of the plastering box 7 respectively, and the lower end of the material shifting plate 13 is in contact with the bottom of the sliding groove 12, so that low-grade sealing isolation is realized on two sides of the material shifting plate 13, and mortar is prevented from leaking in the plastering box 7.
In this embodiment, the overflow port 25 is formed in the upper end of the plastering surface of the plastering box 7, the discharge port 11 is located at the lower end of the plastering surface of the plastering box 7, an expansion port 28 communicated with the discharge port 11 is further formed in the lower end of the plastering surface of the plastering box 7, and the width of the expansion port 28 is gradually increased along a horizontal line in a direction away from the material stirring plate 13. In the implementation of the technical scheme, the mortar amount in the plastering box 7 is kept constant, when the stirring plate 13 extrudes mortar, the liquid level of the mortar can fluctuate, and in order to prevent the mortar from overflowing from the top of the plastering box 7, the upper section of the plastering surface of the plastering box 7 is provided with the overflow hole, so that when the liquid level of the mortar fluctuates, redundant mortar can directly move between the wall surface and the plastering surface from the overflow hole; the lower end of the plastering surface of the plastering box 7 is provided with an expansion port 28 communicated with the discharge port 11, and the width of the expansion port 28 increases progressively along the horizontal line towards the direction far away from the kick-out plate 13, so that the flow speed of the mortar pushed in the plastering box 7 before being attached to the wall surface is reduced, the excessive outflow amount of the mortar in unit time is avoided, and the overflowing amount of the mortar is reduced to the maximum extent.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
