Description

Technical Field

[0001] The utility model relates to the technical field of topographic measurement, in particular to a special measuring device. Background Art

[0002] Land design is an architectural design. Designers make detailed designs for the land planning area and make rational use of its use value. Therefore, it is necessary to measure the terrain in advance and obtain relevant data.

[0003] Therefore, a special measuring device for architectural design in the prior art has a publication number of CN217734926U. When in use, powder is loaded into the storage bucket, and the elastic tube is installed in the buckle. When the storage bucket is pushed, the driving wheel and the wheel axle rotate, and the rotating rod is driven to rotate through the synchronous wheel transmission assembly, thereby driving the arc blade to rotate in the unloading chamber. The powder in the storage bucket is filled between the arc blades and transported to the output pipe. When the speed of the storage bucket changes, the rotation speed of the base arc blade changes synchronously, thereby achieving the effect of real-time adjustment of the powder output rate.

[0004] However, when the speed of the driving wheel increases, the two adjacent arc-shaped blades in the discharge chamber fall on the ground along the elastic tube to form a thin and long marking line. However, when the speed of the driving wheel decreases, the two adjacent arc-shaped blades in the discharge chamber fall on the ground along the elastic tube to form a thick and short marking line, resulting in uneven spreading of the powder, which may easily lead to unreasonable use of the powder.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] like Figure 1-4As shown, a design-specific measuring device comprises a vehicle body 1 for marking terrain, a powder barrel 2, a discharge pipe 8 connected to the bottom of the powder barrel 2, and a running wheel 7 on the vehicle body 1. The function of the above structure refers to the corresponding components of a building design-specific measuring device with publication number CN217734926U. The end face of the wheel shaft of the running wheel 7 is fixedly connected to a wheel body bevel gear 9, and a sprocket wheel 11 is rotatably connected to the vehicle body 1. The end face of the sprocket wheel 11 on the vehicle body 1 is fixedly connected to a transmission bevel gear 10 meshing with the wheel body bevel gear 9. The position of the lower surface of the vehicle body 1 near the discharge pipe 8 is fixedly connected to the wheel body bevel gear 9. The vehicle body 1 is fixedly connected with a mounting seat 17, and a connecting shaft 5 is rotatably connected to the mounting seat 17. A sprocket 11 is also fixedly connected to the connecting shaft 5. The two sprockets 11 are driven by a chain, and the two sprockets 11 rotate synchronously through the transmission of the chain. That is, when the vehicle body 1 moves on the terrain to be surveyed and mapped, the traveling wheel 7 rolls, and the traveling wheel 7 drives the wheel body bevel gear 9 to rotate during the rolling process, thereby realizing the rotation of the transmission bevel gear 10 meshing with the wheel body bevel gear 9, and then realizing the sprocket 11 fixedly connected with the transmission bevel gear 10 drives another sprocket 11 to rotate, and because the wheel body bevel gear 9, the transmission ... The movable bevel gear 10 and the sprocket 11 are of the same size, so the rotation speed of the sprocket 11 on the mounting seat 17 is equal to the rotation speed of the driving wheel 7, and a rotation speed sensor 15 is arranged on the sprocket 11 on the mounting seat 17, and a switch valve 16 is arranged in the discharge pipe 8, and a connecting gear 12 is fixedly connected to the valve handle of the switch valve 16, and an electric push rod 14 connected to the signal of the speed sensor 15 is fixedly connected to the mounting seat 17, and a rack 13 meshing with the connecting gear 12 is fixedly connected to the telescopic end of the electric push rod 14, and the connecting rack 13 is embedded and plugged into the outer wall of the discharge pipe 8, and the control of the prior art is realized. The device processes the rotation speed of the sprocket 11 measured by the rotation speed sensor 15, and then transmits it to the electric push rod 14, so that the electric push rod 14 can be extended and retracted by a certain distance, and then the connecting rack 13 can be moved by a corresponding distance, that is, the connecting gear 12 can be rotated a corresponding number of times, so that the opening degree of the switch valve 16 can be adjusted, and the opening degree of the pipe mouth of the discharge pipe 8 can be adjusted, so as to control the discharge amount. Therefore, when the speed of the driving wheel 7 is too fast, the discharge amount of the discharge pipe 8 can be increased, and when the speed of the driving wheel 7 is slow, the discharge amount of the discharge pipe 8 is small, so as to ensure that the thickness of the falling powder marking line is stable.

[0023] In addition, a stirring rod 6 is rotatably connected in the powder barrel 2, and the top of the stirring rod 6 is connected to a speed regulator 4 fixed in the powder barrel 2. The input shaft of the speed regulator 4 is fixedly connected with a matching gear 3. The stirring rod 6 is used to dredge the bottom of the powder barrel 2, and the top of the stirring rod 6 is fixedly connected to the output shaft of the speed regulator 4. The top of the connecting shaft 5 passes through the vehicle body 1 and the powder barrel 2, and the end face located in the powder barrel 2 is fixedly connected with the matching gear 3. The two matching gears 3 are meshed and connected. The purpose of this scheme is to use the rotation speed of the running wheel 7 to drive the stirring rod 6 to rotate, so as to achieve the stirring and loosening of the powder in the powder barrel 2, and then ensure that the powder can smoothly enter the discharge pipe 8. Specifically, when the running wheel 7 drives the sprocket 11 on the mounting seat 17 to rotate, the sprocket 11 on the mounting seat 17 will drive the connecting shaft 5 to rotate, and the meshing connection of the two matching gears 3 is used to realize that the connecting shaft 5 drives the input shaft of the speed regulator 4 to rotate, and after the speed change action of the speed regulator 4, the stirring rod 6 is rotated at a faster speed, thereby achieving the loosening of the powder in the powder barrel 2.

[0024] Working principle: Pour the powder into the powder barrel 2. When the driving wheel 7 rolls on the terrain, it drives the wheel bevel gear 9 to rotate, thereby realizing the rotation of the transmission bevel gear 10 meshing with the wheel bevel gear 9, and then realizing the sprocket 11 fixedly connected to the transmission bevel gear 10 drives the sprocket 11 on the mounting seat 17 to rotate. The speed sensor 15 measures the speed of the sprocket 11 on the mounting seat 17, and then according to the measured speed, the electric push rod 14 drives the rack 13 to move a distance, and drives the connecting gear 12 to rotate to adjust the opening degree of the switch valve 16, so as to adjust the opening degree of the pipe mouth of the discharge pipe 8, and then control the discharge amount.

[0025] The wiring diagram of the speed regulator 4, the electric push rod 14, the speed sensor 15 and the switch valve 16 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the speed regulator 4, the electric push rod 14, the speed sensor 15 and the switch valve 16 are no longer explained in detail.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
