Based on this, the present invention provides a land area surveying instrument for land reclamation to solve the problems raised in the above-mentioned background technology. Summary of the invention
[0003] The present invention aims at the technical problems existing in the prior art and provides a land area surveying instrument for land reclamation to solve the problems that, on the one hand, the surveying accuracy of the surveying instrument cannot be effectively improved through self-maintenance of the surveying instrument during surveying by the existing device, and on the other hand, it is not convenient to effectively reduce the land area surveying error caused by land factors during surveying.
[0004] The technical solution of the present invention for solving the above-mentioned technical problems is as follows: A land area surveying instrument for land reclamation comprises a carrier and an annular walking belt, a slope surveying module is installed at the front of the carrier, a measuring wheel and two guide wheels are rotatably connected between the inner surfaces of the carrier, the peripheral sides of the measuring wheel and the two guide wheels are transmission-connected to the annular walking belt, a recorder driven by the measuring wheel is fixedly installed on the side of the carrier, an RTK surveying module and a walking belt self-cleaning component driven by a guide wheel are fixedly installed between the inner surfaces of the carrier, a spray marking component driven by another guide wheel is installed on the upper part of the carrier, a walking calibration component cooperating with the spray marking component is installed on the lower part of the carrier, and an electric control module is fixedly installed at the tail of the carrier.
[0005] The beneficial effects of the present invention are:
[0006] The present invention can effectively improve the functionality of the surveying instrument by setting up the slope surveying module, and on the other hand, can effectively reduce the area surveying error caused by the land slope difference when the surveying instrument is measuring the land area slope, thereby assisting in improving the surveying accuracy of the surveying instrument when measuring the land area slope.
[0007] When the present invention is used, when the measuring wheel rotates, the guide wheel and the guide wheel rotate follower. After the guide wheel and the guide wheel rotate follower, the two cleaning plates are driven to move back and forth within the set stroke through the arrangement of structures such as the gear shaft, the return spring, and the semi-guide gear, thereby realizing the reciprocating cleaning of dirt on the surface of the circular walking belt. By realizing the dirt cleaning effect, the cleanliness of the surface of the circular walking belt is effectively guaranteed. By maintaining the cleanliness of the surface of the circular walking belt, the change in the outer diameter of the measuring wheel is effectively reduced, thereby improving the surveying and mapping accuracy of the measuring wheel and the surveying and mapping instrument.
[0008] When the guide wheel rotates in the present invention, the pump housing drives the pigment in the liquid storage tank to be sprayed out by the two marking nozzles at a set flow rate. After the pigment is sprayed out by the two marking nozzles, the automatic calibration of the walking trajectory of the surveying instrument is realized. When the present invention is working, two visual detection probes are set to perform real-time imaging of the spraying trajectories of the two marking nozzles. When the two visual detection probes can both capture the marked spraying trajectories in the center screen of the visual detection probe, it is judged that the walking directions of the carriers are the same. Otherwise, it is judged that the walking directions of the carriers are different. Through the above-mentioned monitoring structure setting, the same degree of walking direction of the surveying instrument during surveying is effectively guaranteed, thereby assisting in improving the surveying and mapping accuracy of the device.

[0011] The beneficial effect of adopting the above further scheme is that before slope mapping, the original height difference between the distance measuring probe and the measuring wheel is measured in advance. During mapping, under the action of the pressure spring, the front wheel at the bottom of the inspection frame is in close contact with the ground to be mapped, and an initial distance value between the distance measuring probe and the inspection frame is obtained. As the carrier and the inspection frame move, the distance between the front wheel and the distance measuring probe changes with the slope of the ground. The single-chip microcomputer calculates the change in the distance value between the distance measuring probe and the inspection frame, and then can quickly calculate the slope value and slope change data of the ground. Through land slope mapping, on the one hand, the functionality of the surveying instrument can be effectively improved, and on the other hand, the area mapping error caused by the land slope difference when the surveying instrument is used for land area slope mapping can be effectively reduced, thereby assisting in improving the surveying accuracy of the surveying instrument when measuring land area.

[0041] The present invention provides the following preferred embodiments
[0042] like Figure 1-9As shown, a land area surveying instrument for land reclamation includes a carrier 1 and a circular walking belt 2, and a slope surveying module is installed at the front of the carrier 1;
[0043] The slope mapping module includes an inspection frame 6, the inner surface of which is rotatably connected with a front wheel 7, the top surface of which is fixedly mounted with two symmetrically arranged guide rods 8, the peripheral side surfaces of the two guide rods 8 are slidably connected with the carrier 1, and pressure springs 9 are sleeved on the peripheral side surfaces of the two guide rods 8 and at positions corresponding to the positions between the inspection frame 6 and the carrier 1, and a distance measuring probe 10 is fixedly installed vertically and facing the inspection frame 6 inside the carrier 1.
[0044] Before slope surveying, the original height difference between the distance measuring probe 10 and the measuring wheel 3 is measured in advance. During surveying, under the action of the pressure spring 9, the front wheel 7 at the bottom of the inspection frame 6 is in close contact with the ground to be surveyed, and an initial distance value between the distance measuring probe 10 and the inspection frame 6 is obtained. As the carrier 1 and the inspection frame 6 move, the distance between the front wheel 7 and the distance measuring probe 10 changes with the slope of the ground. The single-chip microcomputer calculates the change in the distance value between the distance measuring probe 10 and the inspection frame 6, and then can quickly calculate the slope value and slope change data of the ground. Through land slope surveying, on the one hand, the functionality of the surveying instrument can be effectively improved, and on the other hand, the area surveying error caused by the land slope difference when the surveying instrument is used to survey the land area slope can be effectively reduced, thereby assisting in improving the surveying accuracy of the surveying instrument when surveying the land area.
[0045] The inner surfaces of the carrier 1 are rotatably connected with a measuring wheel 3 and two guide wheels 4, and the peripheral sides of the measuring wheel 3 and the two guide wheels 4 are both transmission-connected with the annular walking belt 2;

[0047] The recorder 5 is a common component in the existing distance measuring wheel, and its structural principle and specific composition have been disclosed in existing documents and will not be repeated here;
[0048] An RTK mapping module and a self-cleaning component of a walking belt driven by a guide wheel 4 are fixedly installed between the inner surfaces of the carrier 1;
[0049] The RTK mapping module includes a positioning frame 11, and hinge shafts 12 are fixedly installed on both sides of the positioning frame 11, and the peripheral sides of the two hinge shafts 12 are rotatably connected to the carrier 1;
[0050] The axis of the hinge shaft 12 is parallel to the axis of the measuring wheel 3;
[0051] A universal ball 13 is embedded in the inner wall of the positioning frame 11, and a connecting tube is fixedly installed at the axial position of the universal ball 13. A buffer rod 14 is slidably connected to the inner wall of the connecting tube. The axis of the buffer rod 14 is perpendicular to the axis of the hinge shaft 12. Limiting rings 15 are fixedly installed on the circumferential side surfaces of the buffer rod 14 and at positions corresponding to both sides of the connecting tube. A first buffer spring 16 is fixedly installed between the two limiting rings 15 and the relative surfaces of the connecting tube. A counterweight block 17 is fixedly installed at the bottom end of the buffer rod 14, and an RTK measuring instrument 18 is fixedly installed at the top end of the guide rod 8.
[0052] When in use, the hinged structure of the hinge shaft 12 and the carrier 1 and the embedded structure of the universal ball 13 inside the positioning frame 11 enable the buffer rod 14 and the RTK measuring instrument 18 to be kept self-level before surveying and mapping. The self-leveling of the RTK measuring instrument 18 effectively improves the surveying and mapping accuracy of the RTK measuring instrument 18 during surveying and mapping.

[0054] When working, the RTK measuring instrument 18 cooperates with the recorder 5 to measure the perimeter and shape of the land to be tested, and then quickly measures the land area of the land to be surveyed;
[0055] The walking belt self-cleaning components include a gear shaft 19 and a differential shaft 20 that are rotatably connected between the inner surfaces of the carrier 1, a scraper 22 that is fixedly installed between the inner surfaces of the carrier 1 and fits the annular walking belt 2, and two sets of guide rails 23 that are fixed between the inner surfaces of the carrier 1. The top end of the gear shaft 19 and the tail end of the differential shaft 20 are fixedly installed with differential bevel teeth, and the two differential bevel teeth are meshed with each other. The peripheral side of the differential shaft 20 is connected to a guide wheel 4 through a belt. The peripheral side of the two sets of guide rails 23 The surfaces are slidably connected with cleaning brush plates 24, and the peripheral side surfaces of the two sets of guide rails 23 and the positions corresponding to the two sides of the cleaning brush plates 24 are sleeved with return springs 25. The surfaces of the two cleaning brush plates 24 are fixedly installed with reciprocating toothed plates 26, and the peripheral side surfaces of the gear shaft 19 are respectively fixedly installed with semi-guide gears 27 and rotary cleaning seats 28.

[0057] When in use, when the measuring wheel 3 rotates, the guide wheel 4 and the guide wheel 4 rotate in a driven manner. After the guide wheel 4 and the guide wheel 4 rotate in a driven manner, the two cleaning plates 24 are driven to move back and forth within a set stroke through the arrangement of the gear shaft 19, the return spring 25, the semi-guide gear 27 and other structures, thereby realizing the reciprocating cleaning of the dirt on the surface of the circular walking belt 2. By realizing the dirt cleaning effect, the cleanliness of the surface of the circular walking belt 2 is effectively guaranteed. By maintaining the cleanliness of the surface of the circular walking belt 2, the change of the outer diameter of the measuring wheel 3 is effectively avoided, thereby improving the surveying and mapping accuracy of the measuring wheel 3.
[0058] By setting the rotary cleaning seat 28, the cleaning plate 24 and the two scrapers 22, multi-effect cleaning of the surface of the endless walking belt 2 can be achieved, thereby effectively improving the cleaning effect of the walking belt self-cleaning component on the surface of the endless walking belt 2.
[0059] A spray marking component driven by another guide wheel 4 is installed on the upper part of the carrier 1;
[0060] The spray marking component includes a liquid storage tank 21 fixed to the top surface of the carrier 1, and the liquid storage tank 21 stores pigment inside. The side bottom of the liquid storage tank 21 is fixedly connected to a liquid outlet pipe 29, and a pump housing 30 is fixedly arranged in the middle of the liquid outlet pipe 29. The inner wall of the pump housing 30 is rotatably connected to a pump shaft 31, and the tail end of the pump shaft 31 is fixedly connected to another guide wheel 4. A group of pump blades distributed in a circular array and fitted with the pump housing 30 are fixedly installed on the circumferential side surface of the pump shaft 31 and corresponding to the position inside the pump housing 30. Two marking nozzles 32 with the liquid outlet direction vertically downward are fixedly installed at the bottom of the liquid outlet pipe 29.
[0061] When the guide wheel 4 rotates, the pump housing 30 drives the pigment in the liquid storage tank 21 to be sprayed out by the two marking nozzles 32 at a set flow rate. After the pigment is sprayed out by the two marking nozzles 32, the automatic calibration of the walking track of the surveying and mapping instrument is then realized;
[0062] The type and properties of the pigment in the liquid storage tank 21 can be customized or selected according to actual needs;
[0063] A walking calibration component cooperating with the spray marking component is installed at the lower part of the carrier 1, and an electric control module is fixedly installed at the tail of the carrier 1.
[0064] The electric control module includes an electric control box 33 and a central control panel 34 fixed to the surface of the carrier 1. The electric control box 33 has a battery and a single-chip microcomputer built in. The ports of the battery and the central control panel 34 are electrically connected to the single-chip microcomputer. A handle is fixedly installed at the rear of the carrier 1.
[0065] When working, the storage battery is used to supply power to the power using mechanism in the surveying instrument.
[0066] The walking calibration assembly includes two elastic guide rods 35 which are symmetrically arranged and fixedly installed between the inner surfaces of the carrier 1.

The bottoms of the two tripods 36 are rotatably connected with tail wheels 37. The peripheral side surfaces of the two elastic guide rods 35 and the positions corresponding to the two sides of the tripods 36 are sleeved with second buffer springs 38. Vertically arranged visual inspection probes 39 are fixedly installed between the inner surfaces of the carrier 1 and at the positions corresponding to the two marking nozzles 32.

The visual inspection probe 39 is arranged between the tail wheel 37 and the measuring wheel 3.
[0067] During operation, two visual detection probes 39 are set up to perform real-time imaging of the spraying trajectories of the two marking nozzles 32. When the two visual detection probes 39 can capture the spraying trajectories of the marks in the center of the visual detection probe 39, it is judged that the moving directions of the carrier 1 are the same. Otherwise, it is judged that the moving directions of the carrier 1 are different. Through the above-mentioned monitoring structure setting, the same degree of walking direction during surveying and mapping of the surveying and mapping instrument is effectively guaranteed, thereby assisting in improving the surveying and mapping accuracy of the device.
[0068] An electronic level 40 and an audible and visual alarm 41 are fixedly mounted on the side surfaces of the carrier 1 , respectively. The data ends of the electronic level 40 and the audible and visual alarm 41 are electrically connected to the single chip microcomputer.
[0069] When in use, the electronic level 40 is set so that the carrier 1 tends to be horizontal during surveying. When the carrier 1 is not horizontal during surveying or the visual detection probe 39 detects that the moving direction of the carrier 1 has changed, the single-chip microcomputer controls the sound and light alarm 41 to automatically sound and light alarm to remind the surveyor of the operation.
