Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to an automatic mortar spreading device for masonry projects. Background Technology

[0002] In building construction, the laying of walls requires a large amount of mortar. Traditional mortar spreading mainly relies on manual application using tools such as trowels. This construction method has the following significant drawbacks: It is inefficient and labor-intensive. Manual paving is slow and requires workers to bend over and carry mortar frequently, which greatly consumes their physical strength. Uneven mortar thickness and width make it difficult to ensure consistent thickness of each layer of mortar during manual operation, and mortar tends to overflow to the sides of the bricks, resulting in material waste and a dirty site environment. If the density is insufficient, after manual spreading, it is usually necessary to manually use tools to knock the bricks or mortar to ensure density. Uneven knocking force can easily lead to hollowing and affect the structural strength of the wall. With poor adaptability, traditional paving tools cannot be flexibly adjusted when faced with bricks of different widths or complex masonry angles, making construction extremely inconvenient.

[0003] Therefore, there is an urgent need for an automatic mortar spreading device that can automatically transport mortar, has an adjustable spreading width, and has automatic vibration and tamping functions to improve construction efficiency and masonry quality. Summary of the Invention

[0004] This invention provides an automatic mortar spreading device for masonry engineering, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic mortar spreading device for masonry engineering includes a base on which a support frame is mounted, characterized in that it further includes: A mortar supply system, installed on the upright, includes a lifting seat and a mortar storage tank and a delivery pump installed on the lifting seat; A telescopic rod, one end of which is mounted on the upright; and A mortar spreading device is connected to the other end of the telescopic rod. The mortar spreading device includes a main board, and side baffles are slidably connected to both sides of the bottom surface of the main board. The main board is also provided with an adjustment component for adjusting the distance between the two side baffles. The motherboard is fixed to the top of a mounting plate, and the motherboard is also equipped with a spring-loaded striking component.

[0006] Furthermore, the side baffle includes an anti-overflow part and an adjustment part. A movable seat is fixed on the adjustment part. The adjustment assembly includes a fixed seat fixed on the main board and two adjustment rods rotatably connected to the fixed seat. Both adjustment rods pass through the movable seats on the two adjustment parts, and each adjustment rod is threadedly connected to the movable seat on only one of the adjustment parts. The two side baffles can be moved and adjusted by independently rotating the two adjustment rods.

[0007] Furthermore, a handle is fixed to the outside of the adjusting rod.

[0008] Furthermore, the elastic striking assembly includes a cylinder fixed to the top of the mounting plate, a fixing plate fixedly connected to the side of the mounting plate, a second pressure column fixedly connected to the telescopic end of the cylinder, and a first pressure column fixedly connected to the bottom end of the second pressure column; a pressure sleeve is provided below the first pressure column, the first pressure column extends into the inside of the pressure sleeve, and a buffer spring is connected between the bottom end of the first pressure column and the bottom end inside the pressure sleeve; the pressure sleeve passes through the main plate and is fixedly connected to a pressure plate, and multiple vibrating teeth are fixedly provided at the bottom of the pressure plate.

[0009] Furthermore, a plurality of toothed plates arranged from top to bottom are fixedly connected to the side of the second pressure column, and a guide rod is fixedly connected to the top of the pressure plate. The guide rod passes upward through the main plate, and a top seat is fixedly provided at the top of the guide rod. A striking mounting seat is fixedly connected to the side of the top seat, and a swing rod is rotatably connected to the striking mounting seat. A torsion spring is connected between the swing rod and the striking mounting seat. A swing spring is fixedly connected to one end of the swing rod, and a striking hammer head is fixedly connected to the other end of the swing spring.

[0010] Furthermore, when the cylinder extends and moves the second pressure column, the first pressure column, the pressure sleeve, and the pressure plate downwards until the vibrating teeth are obstructed from contacting the bricks below, the pressure plate, the pressure sleeve, and the guide rod stop moving downwards. As the first and second pressure columns continue to move downwards and compress the buffer spring, the toothed plate on the side of the second pressure column intermittently presses down on the swing rod to cause it to deflect during the downward movement. When the toothed plate disengages from the swing rod, the swing rod resets under the action of the torsion spring, causing the hammer head to strike the top seat, generating vibration and transmitting it to the pressure plate and the vibrating teeth; in the initial natural state, the hammer head is in contact with the top seat.

[0011] Furthermore, a return spring is sleeved on the outer side of the guide rod, with the two ends of the return spring abutting against the top surface of the main board and the bottom surface of the top seat, respectively.

[0012] Furthermore, the upright frame is equipped with a lifting drive motor and a lifting screw. A lifting block is threaded onto the lifting screw. The lifting block is fixedly connected to the lifting seat. A storage tank frame is fixed above the lifting seat. A mortar storage tank is installed on the storage tank frame. The input end of the delivery pump is connected to the mortar storage tank. The output end of the delivery pump is fixedly connected to the delivery pipe. The delivery pipe passes through the main board and extends below it.

[0013] Furthermore, the mortar spreading device also includes a rotating connector, a connecting rod, and a ball head. The upper part of the connecting rod is rotatably connected to the telescopic rod, and the ball head is a universal ball head installed on the rotating connector. The bottom end of the rotating connector is fixedly installed on the main board.

[0014] The present invention has the following advantages: This invention features a unique dual-adjustment rod structure, where each adjustment rod controls only one side baffle. Operators can independently adjust the extension and retraction positions of both baffles by rotating the handle. This not only accommodates bricks of different widths but also allows for flexible offset of the working surface in special conditions such as single-sided wall contact, effectively preventing mortar overflow. The elastic striking assembly of this invention utilizes the stroke difference during cylinder pressing to achieve intermittent striking in continuous operation. After the cylinder drives the vibrating teeth to press down and insert into the mortar, the pressure plate is blocked and stops, while the cylinder continues to press down to compress the buffer spring. At this time, the toothed plate on the second pressure column continues to move down, actuating the swing rod, which, in conjunction with the torsion spring, achieves intermittent continuous striking of the hammer head. The high-frequency vibration is transmitted to the pressure plate through the top seat and guide rod, which greatly improves the compactness of the mortar, avoids hollow areas, and eliminates the need for an additional motor. The structure is ingenious, energy-saving, and efficient. This invention, through the setting of universal ball joints and multi-directional connecting rods, enables the mortar spreading device to automatically adapt to the slight unevenness of the surface of the underlying bricks, ensuring that the spreading device always fits the working surface.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0024] like Figure 1 and Figure 2 As shown, an automatic mortar spreading device for masonry engineering includes a base 1 as a basic support, with casters at the bottom of the base 1 to facilitate the movement of the entire device. A vertical frame 2 is fixed on the base 1. To meet the masonry needs of walls of different heights, the frame 2 is equipped with a height adjustment mechanism, specifically including a lifting drive motor 3 and a lifting screw 4. The lifting drive motor 3 drives the lifting screw 4 to rotate, causing the lifting block 5, which is threadedly connected to the screw, to drive the lifting seat 6 to slide smoothly up and down. A storage tank rack 7 is fixed on the lifting seat 6 for stably placing mortar storage tanks 8. A delivery pump 10 is connected to the bottom or side of the mortar storage tank 8, and the delivery pump 10 continuously and quantitatively delivers mortar to the construction surface below through a delivery pipe 11.

[0025] A telescopic rod 9 is installed laterally at a suitable height on the support frame 2. The length of the telescopic rod 9 can be freely adjusted according to the distance of the construction surface. The core execution component of this invention—the mortar spreading device 12—is suspended at the end of the telescopic rod 9.

[0026] like Figure 3 As shown, the mortar spreading device 12 is connected to the telescopic rod 9 via a universal joint mechanism, which includes a connecting rod 13, a rotating connector 14, and a ball head 15. The upper part of the connecting rod 13 is hinged and rotatably connected to the telescopic rod 9, while the lower end of the connecting rod 13, in conjunction with the ball head 15 and the rotating connector 14, is connected to the upper part of the main board 16. The presence of the universal ball head 15 allows the main board 16 to adaptively adjust its angle within a certain range according to the inclination of the underlying brick surface, ensuring the flatness of the spreading operation.

[0027] like Figure 4 As shown, to prevent mortar from overflowing from both sides during paving and to accommodate different wall thicknesses such as 120mm and 240mm walls without replacing components, side baffles 17 are provided on both sides of the bottom of the main board 16. The side baffles 17 consist of an anti-overflow part 18 on the contact surface and an adjustment part 19 on the top. A fixing seat 20 is fixed on the main board 16, and two parallel adjusting rods 21 are rotatably connected to the fixing seat 20. One end of the adjusting rods 21 has a handle 22.

[0028] The innovation of this invention lies in its staggered threaded drive design: each adjusting part 19 is equipped with a movable seat 23. Although both adjusting rods 21 pass through both movable seats 23 simultaneously, the front adjusting rod 21 only engages with the left movable seat 23, and the rear adjusting rod 21 only engages with the right movable seat 23. Therefore, when a worker rotates one of the handles 22 individually, only one side baffle 17 will undergo lateral displacement. This design enables the device to achieve asymmetrical width adjustment; for example, when the masonry work is close to the original corner or column, only one side baffle can be retracted.

[0029] like Figure 5 and Figure 6 As shown, a spring-loaded striking component 24 is provided above the main board 16. A mounting plate 26 and a fixing plate 27 are fixed to the top of the main board 16, and a cylinder 31 is inverted and mounted on the top of the mounting plate 26. The piston rod of the cylinder 31 is connected downward to the second pressure column 30 and the first pressure column 29 in sequence.

[0030] A pressure plate 25 is provided below, with multiple vibratory teeth at the bottom for inserting into the mortar layer. A guide rod 33 and a pressure sleeve 28 are rigidly connected above the pressure plate 25, both passing upward through the main plate 16. The first pressure column 29 is slidably inserted into the pressure sleeve 28, and both are padded with a buffer spring (not shown in the figure) located inside the pressure sleeve.

[0031] To achieve automatic striking, multiple toothed plates 32 are evenly arranged on the outer wall of the second pressure column 30. The top seat 34 at the top of the guide rod 33 extends out to the side of the striking mounting seat 36. A swing rod 37 is hinged to the striking mounting seat 36, and the swing rod 37 is connected to the striking hammer head 39 through a swing spring 38.

[0032] The working process of the paving and compaction actions in this invention is as follows: First, the delivery pump 10 pumps the mortar to the area below the main board 16. As the telescopic rod 9 or the base 1 moves, the baffles 17 on both sides limit the width of the mortar and smooth it out to form an initial mortar layer. The cylinder 31 is activated to extend it. The cylinder 31 pushes the second pressure column 30 and the first pressure column 29 downward as a whole. Due to the supporting force of the buffer spring, the pressure sleeve 28, guide rod 33 and pressure plate 25 move downward synchronously, and the vibrating teeth are smoothly inserted into the spread mortar; When the vibrating teeth touch the lower hard bricks or the pressure plate 25 is blocked by the reverse resistance of the mortar and cannot move further down, the pressure sleeve 28 and the top seat 34 remain at the current height. However, the cylinder 31 continues to extend, at which point the first pressure column 29 is forced to continue sliding downward inside the pressure sleeve 28, compressing the buffer spring; As the second pressure column 30 continues to move downward relative to the stationary top seat 34, multiple toothed plates 32 on the side wall of the second pressure column 30 will pass the swing rod 37 in sequence. The toothed plates 32 press down on the swing rod 37, causing it to deflect against the torsion spring force, at which point the hammer head 39 is lifted. When the end of a toothed plate 32 passes the swing rod 37, the swing rod 37, which is freed from the constraint, rebounds instantly under the strong restoring force of the torsion spring, causing the hammer head 39 to strike the top seat 34 violently. The mechanical vibration waves generated by the impact are rapidly transmitted along the guide rod 33 to the pressure plate 25 and the vibrating teeth. As the cylinder 31 continuously presses down, multiple toothed plates 32 continuously move and release the swing rod 37, thereby forming a high-frequency continuous impact vibration effect, which allows air bubbles inside the mortar to be expelled, ensuring that the mortar and bricks are tightly bonded. In addition, it can also impact and compact the already laid bricks to improve the quality of masonry. After cylinder 31 retracts, the return spring 35, which is sleeved outside guide rod 33, bounces pressure plate 25 and top seat 34 upwards to reset them, waiting for the next cycle. The function of swing spring 38 is to eliminate the rigid recoil damage at the moment of impact and extend the service life of the equipment.

[0033] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
