Description

Technical Field

[0001] The utility model relates to the technical field of land measurement, in particular to a counting device for land measurement. Background Art

[0002] Land planning is a long-term arrangement for the rational use of land according to the prospects and needs of economic development. Land surveying is the work of measuring and mapping the terrain distribution, quantity and other characteristics of various types of land using methods such as surveying and remote sensing technology.

[0003] Counting equipment is used in land planning and is used to measure the land. Currently, counting equipment uses counting wheels, counters, and displays to measure the land while the counting wheels are moving. However, most current counting equipment is a single-wheel structure, which requires the operator to continuously support the counting equipment while the counting equipment is moving. When the land area is large, the operator's arm is prone to discomfort. When facing rugged land, the counting equipment as a whole may tilt while moving, causing damage to the precision equipment on the counting equipment, which not only affects the accuracy of land measurement, but also affects the efficiency of land planning.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A counting device for land measurement includes a connecting rod 1, a counting wheel 2, a counter 3, and a display 4. The connecting rod 1 is fixedly provided with an anti-slip handrail. The counter 3 can count the number of rotations of the counting wheel 2, and the display 4 can display the number of rotations.

[0021] A support 5 is fixedly mounted on the connecting rod 1, and a guide rod 6 is fixedly mounted inside the support 5. The support 5 is a concave structure, and the guide rod 6 is horizontally arranged. A sliding sleeve is provided on the guide rod 6 with a symmetrically arranged slider 7, and two counting wheels 2 are respectively arranged on the two sliders 7. The guide rod 6 guides and limits the sliders 7, so that the sliders 7 can smoothly pull the counting wheels 2 when moving. By arranging two counting wheels 2 on the counting device, the two counting wheels 2 can support the stability of the counting device, which can ensure that the counting device will not tilt when moving, thereby protecting the precision components on the counting device;

[0022] A moving assembly for moving the slider 7 is installed in the support 5;

[0023] The moving assembly includes two fixed rods 8 fixedly installed in the support 5, and the two fixed rods 8 are slidably sleeved with racks 9, and the racks 9 are fixedly installed with a traction end 10 connected to the slider 7, and the support 5 is rotatably installed with a rotating shaft 11 connected to the racks 9. The fixed rods 8 guide the racks 9, so that the racks 9 can smoothly pull the traction ends 10 when moving, thereby ensuring the stability of the counting wheel 2 when moving;

[0024] The fixing rod 8 is horizontally arranged above the guide rod 6, and a gear 12 meshing with two racks 9 is fixedly installed on the rotating shaft 11, and the two racks 9 are respectively arranged on both sides of the gear 12. The rotating shaft 11 is horizontally arranged, and a handle extending outside the support 5 is fixedly installed on the rotating shaft 11, and a locking bolt detachably connected to the support 5 is threadedly connected to the handle;

[0025] Supplementary explanation: when the land condition is uneven, the handle is pulled counterclockwise, and the handle drives the rotating shaft 11 and the gear 12 to rotate synchronously. When the gear 12 rotates, the two racks 9 move in the opposite direction. When the gear 12 moves in the opposite direction, it drives the two counting wheels 2 to move in the opposite direction. By adjusting the spacing between the two counting wheels 2, the two counting wheels 2 can ensure the stability of the counting device when moving, and the two counting wheels 2 can ensure the measurement accuracy.

[0026] The support 5 is integrally connected with a reinforcing rod 13, and a support frame 14 for supporting the support 5 is installed on a pin on the reinforcing rod 13. The stability of the counting device can be ensured by the deflection of the support frame 14;

[0027] It should be noted that the specific models and specifications of the counting wheel 2, the counter 3, and the display 4 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in the field, so it is not repeated here.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Move the whole to the land to be measured by counting wheel 2;

[0030] When the land is rough;

[0031] The traction handle rotates counterclockwise, and the handle drives the gear 12 to rotate when rotating. When the gear 12 rotates counterclockwise, it can drive the two racks 9 to move in the opposite direction. When the rack 9 slides on the fixed rod 8, it pulls the traction end 10, so that the traction end 10 drives the two sliders 7 to move in the opposite direction on the guide rod 6;

[0032] When the slider 7 slides, the counting wheels 2 are driven to move, so that the distance between the two counting wheels 2 gradually increases;

[0033] When the distance between the two counting wheels 2 is determined, the handle is connected to the support 5 using a locking bolt;

[0034] The moving direction of the counting wheel 2 is guided by the anti-slip handrail, and the counter 3 can count the number of rotations of the counting wheel 2 when the counting wheel 2 rotates, and the display 4 can display the number of rotations;

[0035] When a break is needed, the traction support frame 14 is deflected so that the support frame 14 can contact the ground after the deflection, and the counting device can be supported by the two counting wheels 2 and the support frame 14.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
