Description

Technical Field

[0001] The utility model relates to the technical field of wheat field measuring tools, in particular to a distance measuring device for wheat fields. Background Art

[0002] The existing technology for determining the number of wheat stems per mu is to estimate and measure the number of wheat stems in a single row at fixed intervals, which is helpful for understanding the seedling conditions, estimating fertilizer and water inputs and predicting yields.

[0003] For example, one acre of land is 667 square meters, and the wheat row spacing is 15 centimeters, so you only need to measure the number of wheat stems in a single row of 44 cm, and multiply it by 10,000 to get the number of stems per acre.

[0004] When investigating the number of wheat stems per mu, a tape measure or ruler is currently used to measure a certain spacing, count the number of wheat stems within a single row with a fixed spacing, and then convert it into the number of stems per mu. However, tape measures and rulers are prone to large errors due to manual factors, and because multiple sets of data need to be averaged in some surveys, the error will be further increased. When the number of stems per mu is counted, the error will usually increase, resulting in errors in the final measurement results that exceed the allowable error range. How to reduce the error and reduce the workload of staff has become an urgent problem to be solved in the field of wheat field measurement tool technology. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem in the prior art that when measuring the spacing between wheat fields using a tape measure or a ruler, statistical errors are easily caused due to human operation problems, thereby causing errors in the survey results. The utility model provides a spacing measuring device for wheat fields, which determines the spacing between wheat fields by means of a retractable first telescopic distance rod and a second telescopic distance rod, reduces the error of manual measuring rulers by means of a first positioning rod and a second positioning rod in contact with the ground, and ensures that the spacing formed between the first positioning rod and the second positioning rod is stable by means of the first positioning rod and the second positioning rod.

[0006] The purpose of the utility model is mainly achieved through the following technical solutions:

[0007] A wheat field spacing measuring device comprises a first positioning rod and a second positioning rod, a distance component is arranged between the first positioning rod and the second positioning rod, one end of the distance component is fixed to the first positioning rod, and the other end thereof is fixed to the second positioning rod, the distance component comprises a telescopic sleeve, a first telescopic distance rod and a second telescopic distance rod are arranged on the telescopic sleeve, one end of the first telescopic distance rod is inserted into the telescopic sleeve, and the other end thereof is fixed to the first positioning rod, and one end of the second telescopic distance rod is inserted into the telescopic sleeve, and the other end thereof is fixed to the second positioning rod;

[0008] The first telescopic distance rod and the second telescopic distance rod are symmetrically distributed on both sides of the telescopic sleeve.

[0009] At present, in the prior art, a tape measure or ruler is usually used to determine the spacing between wheat fields. On this basis, the number of wheat stems within the interval measured for a single row is determined to obtain the data on the number of stems per mu in the wheat field. However, when a tape measure is used, the tape measure is prone to bending, resulting in an inaccurate measured distance. When a ruler is used, the ruler is prone to tilt, resulting in an inaccurate measured distance. Both will cause problems with the survey results. In addition, a ruler or tape measure does not have the function of marking lines in a wheat field. The prior art requires the use of other tools to mark lines after using a ruler or tape measure to measure the length. The operation process becomes complicated and consumes too many human and material resources.

[0010] The utility model is based on the first positioning rod and the second positioning rod, ensuring that the first positioning rod and the second positioning rod can accurately provide the measured interval, and then determine the length of the first telescopic distance rod and the second telescopic distance rod through the length of the distance component, so as to effectively provide the determined interval distance of the first positioning rod and the second positioning rod, thereby ensuring that the spacing data of the first positioning rod and the second positioning rod always remain at the determined parameters during measurement. The first telescopic distance rod and the second telescopic distance rod in the utility model can be fixed at a determined length when extended, thereby ensuring the accuracy of the measurement result. The utility model can use the first positioning rod and the second positioning rod to directly draw lines on the field ground with both ends after distance measurement. It is sufficient to directly count the number of wheat stems between the two marking lines, which simplifies the operation process, saves operating tools, and improves measurement efficiency.

[0011] In the utility model, the telescopic sleeve is used to store the first telescopic distance rod and the second telescopic distance rod or to extend the first telescopic distance rod and the second telescopic distance rod, thereby ensuring that the utility model can be portable when stored, and can also ensure that the utility model is convenient for measuring the spacing between wheat fields when extended.

[0014] Further, the driving assembly includes a driving cavity, a gear rod is provided in the driving cavity, one end of the gear rod is inserted into the driving cavity, and the other end of the gear rod extends downward and is fixed to the upper end of the telescopic plug;

[0015] A driving gear is also provided in the driving cavity, and the driving gear is meshed with the gear rod.

[0016] Furthermore, the telescopic plug includes a telescopic section, the upper end of the telescopic section is connected to the driving assembly, and a cone head is fixed to the lower end of the telescopic section.

[0017] Furthermore, the cone head includes a cone, and a plurality of grooves are provided on the cone. The grooves extend along the radial direction of the cone, and the grooves are evenly distributed circumferentially on the cone surface of the cone.

[0018] Furthermore, the telescopic section includes an outer cylinder, the upper end surface of the outer cylinder is connected to the driving assembly, and the lower end surface of the outer cylinder is fixed to the cone head;

[0019] The outer cylinder is filled with weight particles, and the weight particles completely fill the inner space of the outer cylinder.

[0020] In the utility model, the telescopic plug is used to ensure that the rod body can be inserted into the ground, thereby ensuring that the length of the distance component is the distance between the first positioning rod and the second positioning rod; the driving component is used to drive the telescopic plug to retract or extend, thereby preventing the telescopic plug from accidentally injuring a worker; the driving chamber is used to limit the reciprocating motion direction of the gear rod and does not provide space for the driving gear; the reciprocating motion of the gear rod is achieved by the meshing of the driving gear and the gear rod; the telescopic section drives the cone head to reciprocate by extending from the rod body and retracting into the rod body, thereby utilizing the rod The purpose of the body is to accommodate the cone head, and the groove body arranged on the cone body of the cone head can facilitate the first positioning rod and / or the second positioning rod to be inserted into the field soil; the outer cylinder body of the telescopic section is filled with counterweight particles to ensure the stability of the center of gravity of the first positioning rod and the second positioning rod, and the use of the outer cylinder body can balance the counterweight, thereby achieving the purpose of improving the stability of the utility model; the groove body extends along the radial direction of the cone, and the groove body is evenly distributed circumferentially on the conical surface of the cone. Through radial extension, the groove body can be more conveniently inserted into the soil, and through circumferential uniform distribution, the force on the cone can be more uniform.

[0021] Furthermore, the telescopic sleeve comprises an outer sleeve, a first piston sleeve and a second piston sleeve are arranged in the outer sleeve, and the first piston sleeve and the second piston sleeve are symmetrically distributed with the center line of the outer sleeve as the center line;

[0022] The first telescopic distance rod is inserted into the first piston sleeve, and the second telescopic distance rod is inserted into the second piston sleeve. The first telescopic distance rod and the second telescopic distance rod are both provided with latch holes. A latch assembly is provided outside the outer sleeve. The number and position of the latch assemblies correspond to the number and position of the latch holes: one latch assembly corresponds to one latch hole, and the latch assembly can be inserted into the latch hole.

[0023] An air pump is provided between the first piston sleeve and the second piston sleeve, and the air pump is communicated with the outside.

[0024] Furthermore, the latch assembly includes a latch rod, one end of which is inserted into the outer sleeve, and a movable plate is fixed to the other end of the latch rod. A tension spring is provided on the outer sleeve of the latch rod, one end of the tension spring is fixed to the movable plate, and the other end of the tension spring is fixed to the outer sleeve.

[0025] In the utility model, the outer sleeve is used to accommodate the first piston sleeve and the second piston sleeve, and the first piston sleeve and the second piston sleeve are used to accommodate the first telescopic distance rod and the second telescopic distance rod. When the first telescopic distance rod and the second telescopic distance rod slide in the first piston sleeve and the second piston sleeve, the air pump has good air tightness with the end faces of the first telescopic distance rod and the second telescopic distance rod, so that the air pump can push the first telescopic distance rod and the second telescopic distance rod out of the outer sleeve when injecting gas into the outer sleeve, and can pull the first telescopic distance rod and the second telescopic distance rod back into the outer sleeve when pumping air out of the outer sleeve. In the outer sleeve, the pin assembly can be inserted into the pin hole of the first telescopic distance rod and / or the pin hole of the second telescopic distance rod before the first telescopic distance rod or / and the second telescopic distance rod escapes from the telescopic outer sleeve, thereby limiting the position of the first telescopic distance rod and the second telescopic distance rod. Since the position of the pin hole is determined, the length formed by the first telescopic distance rod and the second telescopic distance rod is fixed. The first piston sleeve and the second piston sleeve are symmetrically distributed with the center line of the outer sleeve as the center line, so the length of the distance assembly can also be determined. It can be seen that the length formed by the distance assembly between the first positioning rod and the second positioning rod in the extended state in the utility model always remains consistent.

[0026] In the latch assembly of the utility model, the latch rod is used to be inserted into the latch hole, the tension spring is used to pull the movable plate to compress the latch rod to be inserted into the latch hole, and sealing members for ensuring air tightness are arranged on the end faces of the first telescopic distance rod and the second telescopic distance rod, thereby ensuring that the latch assembly will not cause the thrust of the first telescopic distance rod and the second telescopic distance rod in the outer sleeve or the tension of the first telescopic distance rod and the second telescopic distance rod to be lost.

[0027] Furthermore, the first positioning rod and the second positioning rod are both provided with connection interfaces, and the connection interfaces can be magnetically connected to an external device.

[0046] The present application provides a spacing measuring device for wheat fields, comprising a first positioning rod 2 and a second positioning rod 7, a distance component is provided between the first positioning rod 2 and the second positioning rod 7, one end of the distance component is fixed to the first positioning rod 2, and the other end thereof is fixed to the second positioning rod 7, the distance component comprises a telescopic sleeve 5, a first telescopic distance rod 4 and a second telescopic distance rod 6 are provided on the telescopic sleeve 5, one end of the first telescopic distance rod 4 is inserted into the telescopic sleeve 5, and the other end thereof is fixed to the first positioning rod 2, one end of the second telescopic distance rod 6 is inserted into the telescopic sleeve 5, and the other end thereof is fixed to the second positioning rod 7;

[0047] The first telescopic distance rod 4 and the second telescopic distance rod 6 are symmetrically distributed on both sides of the telescopic sleeve 5 .

[0048] In actual application of this embodiment, the first telescopic distance rod 4 and the second telescopic distance rod 6 are first extended from the telescopic sleeve 5 to obtain a distance component of a determined length, so that the distance between the first positioning rod 2 and the second positioning rod 7 is determined, and the first positioning rod 2 and the second positioning rod 7 are inserted into the ground along the wheat arrangement direction, and the first positioning rod 2 and the second positioning rod 7 are determined as the two end points of the determined distance on the ground of the wheat field, and a counting area is formed between the two end points. At this time, the number of wheat stems in the counting area between the first positioning rod 2 and the second positioning rod 7 is measured, so that more accurate wheat stem number measurement data can be obtained. When multiple measurements and statistics are required in the field, it is only necessary to pull up this embodiment and move it to other places where measurement is required to be performed multiple times. There is no need to re-measure the length. It is only necessary to determine the two end points of the required measurement distance through the first positioning rod 2 and the second positioning rod 7. Due to the reduction of operating steps, the error in the use of tools when manual measurement is performed using a tape measure or a ruler is effectively reduced, and the work efficiency is effectively improved while reducing the error.

[0049] A first counterweight 3 is provided on the first positioning rod 2, and a second counterweight 8 is provided on the second positioning rod 7. The first counterweight 3 is used to balance the center of gravity of the first positioning rod 2, and the second counterweight 8 is used to balance the center of gravity of the second positioning rod 7, so that the first positioning rod 2 and the second positioning rod 7 are not easy to tip over.

[0050] The first positioning rod 2 includes a rod body 21, a telescopic plug 1 is provided at the bottom end of the rod body 21, the axis of the telescopic plug 1 coincides with the axis of the rod body 21, a driving component capable of reciprocating along the axis of the rod body 21 is provided in the rod body 21, and the driving component is connected to the telescopic plug 1;

[0051] The second positioning rod 7 has the same structure as the first positioning rod 2 .

[0052] In this embodiment, the telescopic plug 1 in the first positioning rod 2 is controlled to be retracted and extended by the driving assembly. The telescopic plug 1 can be retracted when not in use to avoid accidental injury to workers, and can also be retracted when leveling the ground. The rod body itself is in contact with the ground, and the alignment of the telescopic plug 1 coincides with the axis of the rod body 21, so that the rod body 21 and the telescopic plug 1 can serve as a reference to each other to ensure that the first positioning rod 2 is perpendicular to the ground, and the same applies to the second positioning rod 7.

[0053] The driving assembly includes a driving cavity 22, in which a gear rod 24 is provided, one end of the gear rod 24 is inserted into the driving cavity 22, and the other end of the gear rod 24 extends downward and is fixed to the upper end of the telescopic plug 1;

[0054] A driving gear 23 is further disposed in the driving cavity 22 , and the driving gear 23 is meshed with the gear rod 24 .

[0055] The driving gear 23 in this embodiment is driven by a motor, and the gear rod 24 is provided with external teeth. The driving gear 23 is meshed with the external teeth on the gear rod 24. When the driving gear 23 rotates forward or reversely, the gear rod 24 can be driven to rise and fall. The rising and falling of the gear rod 24 can effectively drive the rising and falling of the telescopic plug 1, thereby realizing the extension or retraction of the telescopic plug 1 from the rod body 21; the number of external teeth on the gear rod 24 is set according to the required telescopic length.

[0056] The telescopic plug 1 comprises a telescopic section 12 , the upper end of the telescopic section 12 is connected to the driving assembly, and a cone head 11 is fixed to the lower end of the telescopic section 12 .

[0057] The cone head 11 includes a cone 111 , on which a plurality of grooves 112 are disposed. The grooves 112 extend in a radial direction of the cone 111 , and the grooves 112 are evenly distributed circumferentially on the cone surface of the cone 111 .

[0058] The telescopic section 12 includes an outer cylinder 121, the upper end surface of the outer cylinder 121 is connected to the driving assembly, and the lower end surface of the outer cylinder 121 is fixed to the cone head 11;

[0059] The outer cylinder 121 is filled with weight particles 122 , and the weight particles 122 completely fill the inner space of the outer cylinder 121 .

[0060] In this embodiment, the telescopic section 12 is used to provide the telescopic plug 1 with a telescopic amount, the cone head 11 is used to be inserted into the ground, and the outer cylinder 121 of the telescopic section 12 provides a cylindrical shell, so that the telescopic plug 1 is easier to insert into the ground, and the weight particles 122 are flexible through the accumulation of small particles, which is convenient for maintaining the center of gravity of the telescopic plug 1 stable, thereby reducing the probability of the first positioning rod 2 and / or the second positioning rod 7 toppling. The slot body 112 extends radially along the cone 111, and the slot body 112 is evenly distributed circumferentially on the cone surface of the cone 111. By extending radially, the slot body 112 can be more conveniently inserted into the ground, and the circumferentially even distribution of the slot body 112 makes the force on the cone 111 more uniform.

[0061] The telescopic sleeve 5 comprises an outer sleeve 53, in which a first piston sleeve 51 and a second piston sleeve 58 are arranged, and the first piston sleeve 51 and the second piston sleeve 58 are symmetrically distributed with the center line of the outer sleeve 53 as the center line;

[0062] The first telescopic distance rod 4 is inserted into the first piston sleeve 51, and the second telescopic distance rod 6 is inserted into the second piston sleeve 58. The first telescopic distance rod 4 and the second telescopic distance rod 6 are both provided with a latch hole 54. The outer sleeve 53 is provided with a latch assembly. The number and position of the latch assembly correspond to the number and position of the latch holes 54: one latch assembly corresponds to one latch hole 54, and the latch assembly can be inserted into the latch hole 54.

[0063] An air pump 52 is disposed between the first piston sleeve 51 and the second piston sleeve 58 , and the air pump 52 is communicated with the outside.

[0064] The latch assembly includes a latch rod 57, one end of which is inserted into the outer sleeve 53, and the other end of which is fixed with a movable plate 56. A tension spring 55 is provided on the outer sleeve of the latch rod 57, one end of which is fixed to the movable plate 56, and the other end of which is fixed to the outer sleeve 53.

[0065] In the latch assembly of this embodiment, the latch rod 57 is used to insert into the latch hole 54, the tension spring 55 is used to pull the movable plate 56 to compress the latch rod 57 to insert into the latch hole 54, and a seal to ensure air tightness is provided on the end faces of the first telescopic distance rod 4 and the second telescopic distance rod 6, so as to ensure that the latch assembly will not cause the thrust of the first telescopic distance rod 4 and the second telescopic distance rod 6 or the tension of the first telescopic distance rod 4 and the second telescopic distance rod 6 in the outer sleeve 53 to release. The seal in this embodiment adopts a model that can be configured on a large scale in the prior art, so as to facilitate large-scale production of this embodiment.

[0066] In actual application of this embodiment, the air pump 52 on the outer sleeve 53 is turned on, and the air pressure is increased by injecting gas into the outer sleeve 53. Since the end faces of the first telescopic distance rod 4 and the second telescopic distance rod 6 are provided with sealing members to ensure air tightness, when the air pressure in the outer sleeve 53 increases, a thrust is formed on the end faces of the first telescopic distance rod 4 and the second telescopic distance rod 6. The thrust pushes the first telescopic distance rod 4 to slide in the first piston sleeve 51, and pushes the second telescopic distance rod 6 to slide in the second piston sleeve 58, thereby pushing the first telescopic distance rod 4 and the second telescopic distance rod 6 out of the outer sleeve 53. When the latch hole 54 slides to the position of the latch assembly, the latch rod 57 can be effectively inserted into the latch hole 54, and the tension spring 55 acts on the movable plate 56 to push the latch rod 57 into the latch hole 54.

[0067] When the embodiment needs to be stored, the latch rod 57 is pulled out of the latch hole 54 by pulling the movable plate 56. At this time, the air pump 52 exhausts air outwards to form a negative pressure in the outer sleeve 53, thereby pulling the first telescopic distance rod 4 and the second telescopic distance rod 6 back into the outer sleeve.

[0068] In this embodiment, the first telescopic distance rod 4 and the second telescopic distance rod 6 are both marked with scale lines, so that the staff can observe the scale positions intuitively.

[0069] The first positioning rod 2 and the second positioning rod 7 are both provided with a connection interface 9, and the connection interface 9 can be magnetically connected to an external device.

[0070] The connection interface 9 includes an embedding cavity 91, a magnetic attraction plate 92 is disposed in the embedding cavity 91, and the magnetic attraction plate 92 is fixed to the embedding cavity 91;

[0071] A magnetic end 94 is provided in the embedding cavity 91 , and the magnetic end 94 is adsorbed on the magnetic plate 92 . A spring 93 is provided on the magnetic end 94 , and one end of the spring 93 is fixed to the magnetic end 94 , and the other end thereof is fixed to an external device.

[0072] In this embodiment, the connection interfaces on the first positioning rod 2 and the second positioning rod 7 are connected to an external device by magnetic attraction. The external device may be other agricultural tools, which can effectively prevent the loss of the utility model. At the same time, multiple measuring devices of the present embodiment or the same as the present embodiment can also be connected to form a measurement matrix, thereby making the measurement data more accurate.

[0073] The embedded cavity 91 in this embodiment is used to accommodate the installation of the magnetic attraction plate 92. Through the adsorption of the magnetic attraction end 94 and the magnetic attraction plate 92, an effective connection basis is provided. The spring 93 fixed on the magnetic attraction end 94 can avoid rigid connection by elastic expansion, thereby making the connection between this embodiment and the external device more flexible.

[0074] When forming a measurement matrix, the present embodiment is provided with a plurality of second distance measuring devices 10, and the second distance measuring devices 10 have the same structure as the present embodiment, and magnetic ends 94 are fixed at both ends of the spring 93. By respectively inserting the two magnetic ends 94 at both ends of the spring 93 into the adjacent connection interface of the present embodiment and the connection interface of the second distance measuring device 10, the connection between the present embodiment and the second distance measuring device 10 can be formed, thereby facilitating the formation of the measurement matrix.

[0075] When storing this embodiment, both ends of the spring 93 can also be fixedly connected to the magnetic ends 94, one of the magnetic ends 94 is inserted into the embedded cavity 91 and adsorbed with the magnetic plate 92, and the other magnetic end 94 is adsorbed at the storage position, thereby completing the storage of this embodiment.

[0076] Through the setting of the connection interface, the application of the present embodiment is more flexible and the applicability is more extensive.
