Technical Field

[0001] The invention relates to the field of land surveying, and in particular to an automatic slope calculator for comprehensive land improvement. Background Art

[0002] RTK surveying is a commonly used high-precision surveying method that is applicable to a variety of terrains. This method uses a base station and a mobile station to perform surveying. The mobile station is a handheld surveying rod that is held and moved by the surveyor to locate coordinates, while the base station receives and cooperates with the GPS signal of the mobile station to perform surveying and calculations, ultimately obtaining survey data.

[0003] However, in actual operation, when encountering a slope with a steep slope and a smooth land surface, surveyors holding a measuring rod to measure and locate points are very likely to slip and fall on the smooth slope, which not only endangers personal safety but also may damage the measuring instrument.

DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention. Example 1

[0033] like Figure 1-Figure 8 As shown, an automatic slope calculator for comprehensive land improvement includes a telescopic rod 1, a handbook bracket 2 and an RTK host 3; the telescopic rod 1 is composed of an outer tube 101 and an inner rod 102; the bottom of the outer tube 101 is conical; a limiter 103 is installed on the top of the outer tube 101; a handbook bracket 2 is installed on the top of the outer tube 101; a handbook is fixed on the handbook bracket 2; and the RTK host 3 is installed on the top of the inner rod 102;

[0034] It also includes a slide 4, an elastic member 5, a pressure block 6, a connecting rod 7, an insert block 8 and a latch 9; the outer surface of the outer tube 101 is slidably connected to the slide 4; a slip ring 401 is fixedly connected to the bottom of the slide 4; a rubber ring 402 is fixedly connected to the upper side of the slide 4; the longitudinal section of the rubber ring 402 is a right triangle; the outer surface of the outer tube 101 is annular and has at least six inclined grooves 104; each inclined groove 104 is slidably connected to a ball 105; the bottom surface of the rubber ring 402 is in contact with all the balls 105; an elastic member 5 is fixedly connected to the lower side of the slip ring 401; the elastic member 5 is Spring; the other end of the elastic member 5 is fixedly connected with a pressure block 6; the pressure block 6 is slidably connected to the outer tube 101; the outer tube 101 passes through the pressure block 6; the pressure block 6 is a cylinder with an inclined lower surface; eight connecting rods 7 are slidably connected in an annular distribution on the slip ring 401; the lower sides of all connecting rods 7 are commonly fixed to the upper surface of the pressure block 6; a pair of plug blocks 8 are slidably connected on the central axis of the pressure block 6; the plug block 8 is L-shaped; the lower sides of the two plug blocks 8 have the same inclination as the lower surface of the pressure block 6; a connecting ring 802 is welded to the top of the two plug blocks 8; the upper surface of the pressure block 6 is connected to a limiting component.

[0035] The limiting assembly includes a locking block 603 and a latch 9; each plug block 8 is provided with a set of limiting holes 801; two sets of locking blocks 603 are fixedly connected to the upper surface of the pressing block 6; each set of locking blocks 603 is slidably connected to a latch 9; each latch 9 corresponds to a plug block 8.

[0036] A cylindrical protective cloth 10 is connected between the slip ring 401 and the pressing block 6, which is used to prevent dirt and other debris from adhering to the surfaces of parts such as the outer tube 101 and the elastic member 5.

[0037] An even number of pressing teeth 601 are welded on the lower surface of the pressing block 6 ; pressing grooves 602 are formed between adjacent pressing teeth 601 .

[0038] The bottom of the pressing teeth 601 and the inserting block 8 are both configured to be conical, so as to facilitate insertion into the soil.

[0039] The pressing block 6 is made of stainless steel with a counterweight; increasing its own weight facilitates pressing down to form a trampling pit, while extending its service life when used on land with a certain moisture content and hardness.

[0040] The connecting rod 7 is distributed in a ring shape on the outside of the elastic member 5; the protective cloth 10 is surrounded on the outside of the connecting rod 7; when the slip ring 401 is pressed down to cause the protective cloth 10 to deform and shrink, the connecting rod 7 supports the protective cloth 10 so as not to deform inward, avoiding contact with the elastic member 5 and affecting its shrinkage. At the same time, the protective cloth 10 is surrounded on the outermost side to prevent the internal parts from being adhered to mud and affecting their movement.

[0041] The outer surface of the slide tube 4 is provided with an anti-skid structure to prevent slipping when holding.

[0042] When encountering a slope with a steep gradient and a smooth land surface, surveyors are very likely to slip and fall on the smooth slope when measuring with an RTK measuring rod, which will endanger personal safety and measuring instruments. Using tools to dig pits on the slope surface to prevent slipping is inefficient and extremely labor-intensive for slopes that require a large number of measuring points.

[0043] When the surveyor uses the present invention, he adjusts the height of the inner rod 102 extending out of the outer tube 101 through the limiter 103, and drives the present invention to move by holding the upper middle part of the slide cylinder 4. The pressing block 6 of the present invention is a cylinder with an inclined bottom. When it is necessary to dig a stepping pit on a slope, the vertical long side of the pressing block 6 is directed to the uphill direction, and then the present invention is directly and quickly inserted into the land from above the excavation point. At this time, the lower side of the outer tube 101 is conical and can be easily inserted into the land until the outer tube 101 can no longer go deeper into the land. The slide cylinder 4 held by the surveyor will slide downward relatively along the surface of the outer tube 101, and the slip ring 401 will squeeze the elastic member 5 downward, and the elastic member 5 will be pushed downward. The elastic member 5 pushes the pressing block 6 with an inclined bottom to be inserted downward into the ground. At the same time, the reaction force of the pressing block 6 in contact with the ground synchronously squeezes the elastic member 5, so that both ends of the elastic member 5 are compressed and contracted. At this time, the pressing block 6 is provided with a counterweight to increase the inertia of the pressing block 6 when it is pressed downward, so that the pressing block 6 presses a trampling pit with the same shape as its lower side on the surface of the sloped land. The surveyor walks on the slope by stepping on the trampling pit to avoid slipping and falling, which would damage personal safety and measuring instruments. At the same time, there is no need to use other tools. In the process of holding the present invention for moving and fixing, the trampling pit is directly formed by the present invention, which improves the moving efficiency and saves energy.

[0044] Since the RTK measurement method requires multiple fixed points, the present invention forms a trampling pit by pressing down with gravity. After repeated attempts, the surveyor's hands are easily tired. In addition, when the present invention is inserted into the ground and is relatively stable, more effort is required to pull it out. After the pressure block 6 is pressed down to form a trampling pit, the elastic member 5 is in a compressed state by the slip ring 401 and the pressure block 6. At this time, the surveyor's hand stops applying the downward extrusion force on the slide cylinder 4 and lifts the slide cylinder 4 upward. The slide cylinder 4 drives the slip ring 401 to move upward. The elastic member 5 loses the extrusion of the slip ring 401 and will quickly stretch upward, squeezing the pressure block 6, thereby compressing the elastic member 5. The reaction force formed by the block 6 and the ground pushes the slide 4 upward in the opposite direction. When the slide 4 moves upward relative to the outer tube 101 until the top of the slide 4 contacts the bottom of the notebook bracket 2, the slide 4 pushes the notebook bracket 2 to drive the outer tube 101 to be pulled out of the ground. When the top of the slide 4 contacts the bottom of the notebook bracket 2, the slip ring 401 drives the connecting rod 7 to pull up the pressure block 6 and move together. Therefore, the surveyor only needs to apply an extrusion force when pressing down and release the extrusion force after the stepping pit is formed. The present invention automatically bounces up under the reaction force of the elastic member 5, and there is no need to apply a lifting force, which saves energy and is easy to use.

[0045] It should be noted that when the surveyor holds the slide 4 to press the present invention downward, the bottom surface of the rubber ring 402 on the upper inner side of the slide 4 contacts the upper side of the ball 105, pushing the ball 105 to squeeze the outer tube 101 and move downward synchronously with the slide 4, and the bottom of the outer tube 101 is inserted into the ground. When the outer tube 101 can no longer be inserted into the ground, the downward pressure applied by the surveyor to the slide 4 will force the rubber ring 402 that squeezes the ball 105 to deform, so that the rubber ring 402 passes over the ball 105 downward, and then the slide 4 can slide relative to the outer tube 101. When the surveyor lifts the present invention, the slide 4 slides upward relative to the outer tube 101, and the cross-section of the rubber ring 402 is a right triangle, and the hypotenuse of the triangle contacts the ball 105, pushing the ball 105 obliquely upward into the inclined groove 104, so that the rubber ring 402 passes over the ball 105 and moves upward until the top of the slide 4 contacts the bottom of the notebook holder 2.

[0046] Furthermore, when the pressing block 6 is pressed down to form a trampling pit, the pressing teeth 601 on the bottom of the pressing block 6 press out anti-skid stripes on the surface of the trampling pit, thereby increasing the anti-skid friction and preventing the surveying and mapping institute from slipping and falling on the smooth surface of the trampling pit.

[0047] Some slopes are land mixed with various debris such as stones and soil. It is difficult to form a suitable trampling pit only by pressing the pressing block 6. For such land, the surveyor places the present invention vertically. In the initial state, Figure 5 As shown, the lower side of the plug block 8 is flush with the lower surface of the pressing tooth 601. Then the surveyor pulls out the latch 9 to release the lock on the plug block 8, and then holds or steps on the pressing rod 803 to move it downward. The pressing rod 803 pushes the plug block 8 to slide downward on the pressing block 6 until it is as shown in FIG. Figure 6After the surveyor has moved to the position shown in the figure, the limit hole 801 on the upper side of the plug block 8 will be aligned with the locking block 603, and then the surveyor will re-insert the latch 9 into the locking block 603 and the limit hole 801 to lock the plug block 8 in the current position. At this time, the lower side of the plug block 8 will protrude from the lower surface of the pressing block 6. When the surveyor needs to open a trampling pit, the present invention will be vertically inserted into the ground. Different from the method of pressing down to form a trampling pit, the surveyor does not need to press downward with great force, but only needs to insert the bottom of the outer tube 101 into the ground. After the lowest point of the plug block 8 contacts the ground, the slide cylinder 4 is held to drive the present invention to rotate back and forth clockwise and counterclockwise when viewed from top to bottom, and at the same time, a downward squeezing force is applied to the present invention, and then the rotation of the slide cylinder 4 drives the slip ring 401 to rotate, and the slide The ring 401 drives the pressure block 6 to rotate through the fixing of the connecting rods 7, and the pressure block 6 drives the plug block 8 to rotate, and then the plug block 8 will rotate and penetrate into the ground. The action of the plug block 8 rotating and moving downward will push the stones and soil to the surroundings, thereby forming a trampling pit. The lower sides of the two plug blocks 8 have the same slope as the lower surface of the pressure block 6. The shape of the trampling pit formed by the rotation of the plug block 8 is the same as the shape of the trampling pit formed by pressing the pressure block 6 downward. Therefore, in the case where it is difficult to form a suitable trampling pit only by pressing the pressure block 6 downward, the present invention can push the stones and soil to the surroundings by the action of the plug block 8 rotating and moving downward to form a trampling pit. The way of forming the trampling pit is changed according to the scene, thereby improving the practicality of the present invention.

[0048] It should be noted that the lower side of the insert block 8 is conical and sheet-shaped, and is easier to insert into the soil than the pressing block 6. Therefore, when the pressing block 6 cannot be pressed down to form a trampling pit, the insert block 8 can be inserted into the soil and form a trampling pit in a rotating manner.

[0049] Furthermore, in order to prevent stones, soil and other debris from splashing onto the elastic member 5 and the connecting rod 7 during the use of the present invention and affecting the movement of the parts, a protective cloth 10 is connected between the slip ring 401 and the pressure block 6 to protect the internal parts. The protective cloth 10 will adaptively shrink and stretch as the distance between the slip ring 401 and the pressure block 6 changes. Example 2

[0050] On the basis of Example 1, Figure 5-Figure 9 As shown, it also includes a cleaning component, which includes a connecting cover 21 and a cleaning strip 22; a pair of arc-shaped connecting covers 21 are slidably connected to the outer side of the pressure block 6; a pair of movable cavities 604 are opened on the outer side of the pressure block 6; a connecting block 2101 is fixedly connected to the inner side of each connecting cover 21; the connecting block 2101 is located in the corresponding movable cavity 604; a group of elastic members 2102 are fixedly connected to the lower side of each connecting block 2101; the elastic member 2102 is a spring; a group of cleaning strips 22 that are compatible with the shape and number of the pressing groove 602 are fixedly connected to each connecting cover 21; the cleaning strips 22 are located in the corresponding pressing groove 602; at least four pressing rods 803 are fixedly connected to the lower side of the connecting ring 802.

[0051] The connecting cover 21 is made of stainless steel to increase the service life when used on soil with a certain humidity or hard soil.

[0052] The cleaning strip 22 is provided with a rubber layer on its surface so as to closely fit the inner wall of the pressing groove 602 .

[0053] After using the present invention to dig trample pits on land with high adhesion for many times, some soil will remain in the pressing groove 602, and with the increase of residual soil each time and the squeezing of the pressing block 6, the residual soil is gradually pressed in the pressing groove 602, so that the lower surface of the pressing block 6 gradually becomes a flat inclined surface, and the pressing teeth 601 lose the function of forming anti-skid stripes on the surface of the trample pit and improving the anti-skid friction; therefore, when the user finds that a large amount of soil remains in the pressing groove 602, the surface of the trample pit pressed by the pressing block 6 is flat, and there are no anti-skid stripes formed by the pressing teeth 601, the present invention is lifted up vertically and suspended in the air, and then the locking and fixing of the plug 8 by the latch 9 is released, and then the connecting ring 802 is stepped on by hand or foot to push the plug 8 to slide downward on the pressing block 6, such as Figure 8 As shown, during the downward movement of the connecting ring 802, the bottom of the pressing rod 803 contacts the top of the corresponding connecting cover 21, and the connecting cover 21 is pressed to move downward. The connecting cover 21 drives the connecting block 2101 to press the corresponding elastic member 2102 downward. The connecting cover 21 drives the corresponding cleaning bar 22 to move downward. The cleaning bar 22 moves downward from the corresponding pressing groove 602, and pushes the remaining soil in the pressing groove 602 downward, so that the bottom surface of the pressing block 6 is restored to the concave and convex stripes formed by the pressing teeth 601 and the pressing groove 602. When the pressing block 6 presses the land, the pressing teeth 601 form anti-slip stripes on the surface of the trampling pit to avoid the pressing. The surface of the treading pit formed by block 6 is smooth, and the user is prone to slipping when stepping on it; after the pressure groove 602 is cleaned, the user holds the connecting ring 802 and lifts it upward to the required height to reset it, aligns the corresponding limiting hole 801 with the locking block 603, and re-passes the latch 9 through the locking block 603 and the limiting hole 801 to lock and fix the plug block 8 and its connecting parts. After the connecting ring 802 moves up, the pressure rod 803 will release the squeezing on the top of the connecting cover 21, and then the compressed elastic member 2102 will stretch, pushing the connecting block 2101 to drive the connecting cover 21 to move upward and reset, and the cleaning strip 22 will be retracted to the top of the corresponding pressure groove 602.

[0054] It should be noted that when the cleaning strip 22 moves downward, the upper surface does not leave the pressing groove 602 , and thus the pressing groove 602 in the upper space of the cleaning strip 22 is not connected to the outside world, and soil cannot enter the upper side of the cleaning strip 22 .

[0055] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
