Description

Technical Field

[0001] The invention relates to the technical field of garden engineering powder material setting out machines, in particular to an engineering powder material setting out machine. Background Art

[0002] During the construction process, it is necessary to use gray lines to lay out the actual size on the construction ground according to the design size of the drawings in the early stage. According to the needs such as foundation pit excavation, the project usually uses plastic buckets to pack lime, and spreads lime lines as marks by grabbing lime with hands. Some use shovels on the construction site, hold the shovel and keep walking forward, and use a piece of wood or a steel bar head to knock and shake to complete the white lime line spreading work. This line spreading method has the following main defects: 1. Plastic buckets are inconvenient to carry; 2. Shovel, wood, and steel bar heads are inconvenient to carry; 3. Line spreading takes a long time and is not efficient. Each time you grab a little lime with your hands, and then the white lime leaks from the hand seams, which is not only slow but also hurts the skin. Usually, it takes many times to complete the entire line setting; 4. The thickness, width and narrowness of the gray line are uneven, and the effect is not good; 5. Lime waste is relatively serious, polluting the surrounding environment; 6. In construction projects, long-term contact with lime will cause harm to the hands of users, and it is easy to stick to the body and hands and is difficult to clean. Because people are close to the operating surface, the dust generated when spreading lime can easily infringe on the health of the operator through breathing.

[0003] Therefore, it is a problem worthy of study to provide a new engineering line laying and ash spreading tool which has a simple structure, is easy to operate, saves resources during operation, avoids direct contact of the hands, reduces harm to the health of the constructors, and improves the accuracy and efficiency of the marking.

[0031] like Figure 1 As shown, the steering mechanism in this embodiment includes a motor 7, a reducer 8, a driving gear 9, and a driven half-tooth 10. The driven half-tooth 10 is arranged at the rear end of the front wheel frame 3, and the driving gear 9 is rotatably connected to the bearing plate 1. The driving gear 9 is meshed with the driven half-tooth 10. The motor 7 and the reducer 8 are arranged above the driving gear 9 and are vertically fixedly installed on the outer side of the front wall of the charging box 5. The output end of the motor 7 is connected to the reducer 8, and the output end of the reducer 8 is connected to the driving gear 9. It also includes an electric control board, and the motor 7 is connected to the electric control board circuit.

[0032] Preferably in the above technical solution, the driving gear 9 is a worm gear structure, and the driven half gear 10 is a turbine. The transmission structure of the turbine and worm gear has a self-locking function to prevent the front wheel assembly 4 from deflecting.

[0033] like Figure 3As shown, a conveying mechanism is provided at the lower end of the carrier plate 1, and the conveying mechanism includes a shell 25, in which a spiral worm 11 is rotatably connected, an upper end surface of the shell 25 is provided with an opening connected to a feed port 12 of a charging box 5, and a lower end surface of the shell 25 is provided with a discharge port 13.

[0034] like Figure 3 As shown, it also includes a linkage mechanism, which includes a linkage shaft 14, which is rotatably arranged at the lower end of the carrying plate 1, one end of the linkage shaft 14 is connected to the spiral worm 11, and the other end of the linkage shaft 14 is provided with a driven bevel gear 15. A rotating shaft 16 is connected between a group of rear wheel assemblies 2, and a driving bevel gear 17 is arranged on the rotating shaft 16. The driving bevel gear 17 is meshed with the driven bevel gear 15. The linkage mechanism links the rear wheel assembly 2 with the conveying mechanism, so that the material is unloaded only when the layout machine moves, and the material is unloaded evenly, thereby reducing the waste of white ash.

[0035] In order to facilitate the steering of the front wheel assembly 4, preferably, the front wheel assembly 4 may not be a wheel, but may move in the form of a rolling ball; and the operation mode of the rolling ball is already a prior art and will not be described in detail here.

[0036] Embodiment 2: Figure 1-7 As shown, the rotating shaft 16 is a flower shaft, and the active bevel gear 17 is slidably connected to the flower shaft. The flower shaft also includes a dotted line layout mechanism, which includes a toothless bevel gear 18. The toothless bevel gear 18 and the active bevel gear 17 are relatively slidably arranged on the flower shaft. The toothless bevel gear 18 is connected to the active bevel gear 17, that is, the toothless bevel gear 18 and the active bevel gear 17 can be integrated, and also includes a reversing mechanism. The toothless bevel gear 18 rotates with the driving linkage shaft 14 through the reversing mechanism. The reversing mechanism includes a reversing shaft 28, a reversing bevel gear 29, an active reversing gear 30, and a driven reversing gear 31. The reversing shaft 28 is rotatably connected to the bottom of the bearing plate 1, and the reversing bevel gear 29 is connected to one end of the reversing shaft 28. The active reversing gear 30 is connected to the reversing shaft 28, and the driven reversing gear 31 is connected to the linkage shaft 14. The active reversing gear 30 and the driven reversing gear 31 are meshed with each other.

[0037] Preferably, the toothless bevel gear 18 and the active bevel gear 17 are provided with a sliding mechanism, and the sliding mechanism includes a clamping frame 26, and sliding sleeves 27 are rotatably provided at both ends of the clamping frame 26. The outer end surfaces of the toothless bevel gear 18 and the active bevel gear 17 are provided with an annular groove 19, and the sliding sleeve 27 is connected to the annular groove 19. The outer end of the clamping frame 26 is connected to the lever 20, such as Figure 8As shown, the function of the sliding mechanism is to transform the connection between the active bevel gear 17 or the toothless bevel gear 18 and the linkage shaft 14. Since the active bevel gear 17 and the toothless gear are on the same shaft, the active bevel gear 17 and the toothless gear are directly meshed with the driven bevel gear 15 respectively, and the direction transmitted to the driven bevel gear 15 is opposite. In order to enable the spiral worm 11 to advance normally and unload normally, a reversing shaft 28, a reversing bevel gear 29, an active reversing gear 30, and a driven reversing gear 31 are arranged under the bearing plate 1. After the toothless bevel gear 18 is meshed with the reversing bevel gear 29, and the active reversing gear 30 and the driven reversing gear 31 are reversed, the steering direction of the spiral worm 11 transmitted by the toothless bevel gear 18 is realized.

[0038] Preferably, a connecting frame 21 is provided on the clamping frame 26, and the upper end of the connecting frame 21 is connected to the slide plate 23. A screw 24 is provided in the slide groove of the slide plate 23, and the bottom end of the screw 24 is engaged with the supporting plate 1. The slide plate 23 is regulated by tightening the screw 24, and then the lever 20 and the clamping frame 26 are fixed.

[0039] Furthermore, the driven half gear 10 is marked with a scale (not shown in the figure), and a pointer 22 is fixedly set at the center of the driven half gear 10. The direction of the pointer 22 remains unchanged and is always along the center line of the bearing plate 1, which can indicate the rotation angle of the front wheel assembly 4.

[0040] In order to ensure the accuracy of the layout machine operation, the push handle 6 can be made in a straight line with the discharge port 13, the center of the driving gear 9, and the front wheel assembly 4; and in order to stop the movement at any time, a corresponding brake mechanism can be set on the layout machine, and the brake mechanism belongs to the existing technology and will not be repeated here.

[0041] Working principle: The use of engineering powder sampler usually involves the following steps:

[0042] 1. Design planning: Before starting the project, the designer will plan the areas that need to be marked according to the garden design drawings, especially marking the characteristic coordinate points. Sensors can be embedded in the coordinate points in advance. These sensors will be recognized by the layout machine. These coordinate points are used as the transformation points of straight lines, dotted lines, and arcs.

[0043] 2 Machine preparation: Prepare the engineering powder setting machine and check its working status, whether the main loading box 5 is unloading normally and whether the reversing mechanism is accurately controlled.

[0044] 3. Littering operation: The operator pushes the layout machine forward by means of the push handle 6, and the layout machine starts to move along the predetermined starting point coordinate point, such as Figure 3As shown, when straight line lofting is required, the front wheel assembly 4 is on the center line of the carrier plate 1, pushing the lofting machine, the rear wheel assembly 2 rotates to drive the active bevel gear 17 to rotate, the active bevel gear 17 drives the meshing driven bevel gear 15 to rotate, and then drives the linkage shaft 14 to rotate, and the linkage shaft 14 drives the spiral worm 11 to rotate, as shown in FIG. Figure 5 As shown, the lime is driven to enter the housing 25 from the discharge port 12 of the charging box 5, and is driven forward by the spiral worm 11 to be discharged evenly from the discharge port 13 of the housing 25;

[0045] After drawing the straight line and reaching the starting coordinate of the arc line, Figure 1 As shown, the motor 7 is started, and the motor 7 drives the driving gear 9 to rotate through the reducer 8, and drives the meshing driven half gear 10 to rotate a certain angle, completing the reversal of the front wheel assembly 4. After the operator pushes the layout machine again, the layout machine starts to layout the circular arc line;

[0046] When you need to draw a dotted straight line or arc, such as Figure 6-8 As shown, when the lever 20 is moved, when the active bevel gear 17 and the driven bevel gear 15 are meshed, the rear wheel assembly 2 is pushed, and the spiral worm 11 is pushed forward at a uniform speed to achieve solid line lofting. When the lever 20 makes the toothless bevel gear 18 mesh with the reversing bevel gear 29, it drives the active reversing gear 30 and the driven reversing gear 31 to rotate, and drives the reversing bevel gear 29 to intermittently move forward to achieve dotted line lofting.

[0047] 4Construction basis: The scattered gray lines provide an intuitive construction reference for construction workers, ensuring that the project is carried out accurately according to the design.

[0048] Engineering powder layout machine improves the efficiency and accuracy of garden engineering layout, reduces the labor intensity and time consumption of manual layout, and also improves the quality of the project. In modern garden construction, this kind of mechanical equipment has been widely used.

[0049] In summary,

[0050] The engineering powder setting out machine puts lime into a loading box 5, and the operator pushes the machine directly on the ground by pushing the handle. The rear wheel assembly 2 drives the conveying mechanism through the linkage mechanism, and the white powder in the box falls evenly from the discharge port 13 to complete the setting out. This not only saves operation time and improves work efficiency, but also avoids direct contact between workers' hands and lime, thereby improving the sanitary conditions when drawing lime lines and reducing the damage of dust to the health of operators. The lime is only discharged when it is pushed forward, which also saves costs and prevents the waste of lime.

[0051] The engineering powder material setting out machine can mark coordinates in advance on the planned ground, and control the rotation direction of the front wheel assembly 4 through the steering mechanism, so as to set out a straight line or an arc line when reaching a predetermined coordinate point, thereby completing a predetermined setting out task.

[0052] The engineering powder material setting out machine can realize the conversion of setting out solid lines or dotted lines through the dotted line setting out mechanism when the reversing mechanism is operated. Specifically, the lever 20 is toggled, and when the active bevel gear 17 and the driven bevel gear 15 are meshed, the rear wheel assembly 2 is pushed, and the spiral worm 11 is pushed forward at a uniform speed to realize solid line setting out. When the lever 20 makes the toothless bevel gear 18 mesh with the reversing bevel gear 29, it drives the active reversing gear 30 and the driven reversing gear 31 to rotate, and drives the reversing bevel gear 29 to intermittently move forward to realize dotted line setting out, thereby adapting to various setting out requirements.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
