Description

Technical Field

[0001] This invention relates to an agricultural tool, specifically to a crop ridge detector and its detection method. Background Technology

[0002] Ridge planting improves soil aeration and permeability, enhances the soil's ability to retain moisture and heat around the crop roots, promotes root development, accelerates fertilizer decomposition, increases water and nutrient absorption, facilitates irrigation and drainage, improves ventilation, and increases sunlight exposure and yield. Most root and tuber crops in my country, such as sugar beets, potatoes, peanuts, and radishes, especially in northern regions, utilize ridge planting. However, during harvesting, deviations in the digging shovel's direction can lead to missed or under-digging, or damage to tubers. Furthermore, to minimize losses, drivers must maintain high concentration on the ridges, constantly adjusting the direction, resulting in high labor intensity. The ridge-laying performance is also susceptible to human error, making it difficult to guarantee harvesting effectiveness and efficiency. Therefore, automated ridge-laying harvesting is often necessary for ridge-laying crops. To improve the accuracy of automated ridge-laying monitoring systems, it is necessary to predict in advance the deviation distance and shape variation range of different crop ridges. However, the detection of crop ridge shape in my country is currently mainly based on manual observation, lacking professional ridge shape detection equipment, resulting in low detection accuracy and susceptibility to human factors. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of the lack of professional ridge shape detection equipment in the prior art, and to provide a crop ridge shape detector.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] In a first aspect, the present invention provides a crop ridge detector, which is assembled from an I-shaped frame and two rectangular frames to form the main body of the ridge detector, and each of the two rectangular frames is equipped with a set of ridge shape extractors.

[0006] Each of the rectangular frames is composed of two parallel first guide rails and two parallel second guide rails connected together;

[0007] The I-shaped frame is formed by two parallel third guide rails connected by a fourth guide rail. The I-shaped frame is divided into two open assembly spaces by the fourth guide rail.

[0008] Two rectangular frames are installed in two assembly spaces of the I-shaped frame. Each rectangular frame is assembled onto two fourth guide rails on both sides of its assembly space via second guide rails on both sides. The two rectangular frames and the I-shaped frame together enclose a ridge-shaped detection space with an open bottom and a trapezoidal cross-section. Each pair of second and fourth guide rails constituting the assembly relationship is adjustablely locked by a locking component. Before the second and fourth guide rails are locked, there are two allowable adjustment dimensions. The first adjustment dimension is the fixed position of the fourth guide rail on the second guide rail, and the second adjustment dimension is the angle between the fourth guide rail and the second guide rail.

[0009] The ridge-shaped shaper assembly is mounted on the first guide rail at the bottom of each rectangular frame via a detachable connector; each ridge-shaped shaper assembly contains multiple shapers, which are continuously installed along the extension direction of the first guide rail, for shaping the bottom side of the ridge.

[0010] As a preferred embodiment of the first aspect above, the locking assembly between each pair of second and fourth guide rails constituting an assembly relationship includes a first bolt and nut connector, a second bolt and nut connector, and a positioning plate, wherein the surface of the fourth guide rail has a groove along the guide rail direction.

[0011] The first bolt and nut connector includes a first slider nut and a first self-locking bolt. The first slider nut is installed in the groove on the surface of the fourth guide rail and forms a sliding fit. The second guide rail has an elongated hole along the direction of the guide rail. The first self-locking bolt passes through the elongated hole, penetrates the second guide rail, and is screwed into the first slider nut.

[0012] The second bolt and nut connector includes a nut and a T-bolt. The bolt head of the T-bolt is installed in the groove on the surface of the fourth guide rail and forms a sliding fit. The bolt body of the T-bolt passes through the positioning plate and forms a threaded fit with the nut. The positioning plate can be translated along the fourth guide rail and inserted horizontally at the angle between the second and fourth guide rails, limiting the angle between the two guide rails from further expanding.

[0013] As a preferred embodiment of the first aspect, the detachable connector includes multiple sets of hooks and quick clamps. In the ridge-shaped shaper assembly, a set of hooks and quick clamps are provided between each pair of adjacent shapers for installation. The hooks and quick clamps are both fixed on the first guide rail at the bottom of the rectangular frame. The hooks have U-shaped grooves, and the splicing position of the two adjacent shapers passes through the U-shaped grooves. After one free end of the U-shaped groove of the hook is tightened by the quick clamp, the shaper is pressed onto the first guide rail for fixation.

[0014] As a preferred embodiment of the first aspect, the first and second guide rails, as well as the third and fourth guide rails, are detachably fixed by angle brackets.

[0015] As a preferred embodiment of the first aspect, the first guide rail surface has a groove along the guide rail direction, and the hanging ear is adjustablely fixed by a set of second self-locking bolts and a second slider nut. The second slider nut is installed in the groove on the surface of the first guide rail and forms a sliding fit. The second self-locking bolt passes through the hanging ear and is screwed into the second slider nut.

[0016] As a preferred embodiment of the first aspect mentioned above, the guide rails used in the I-shaped frame and the rectangular frame are all made of profiles with grooves on all four sides.

[0017] As a preferred embodiment of the first aspect mentioned above, both the third guide rail and the first guide rail are assembled using a multi-segment splicing method.

[0018] As a preferred embodiment of the first aspect, the adjacent sections of the third guide rail and the first guide rail are fixed together by a slotted connector and a locking screw.

[0019] As a preferred embodiment of the first aspect, the shapers in the ridge-shaped shaper assembly are provided with tongue and groove joints on both sides, and adjacent shapers are paired and connected through the tongue and groove joints.

[0020] In a second aspect, the present invention provides a method for detecting crop ridge shape using a crop ridge shape detector as described in any of the embodiments of the first aspect above, comprising:

[0021] S1. Based on the length of the ridge to be tested, guide rail segments of different lengths are spliced ​​together to ensure that the lengths of the third and first guide rails in the I-shaped frame and the rectangular frame are not less than the length of the ridge to be tested. At the same time, a set of ridge shape taking device combinations are installed on the first guide rails at the bottom of the two rectangular frames, and the number of shape taking devices in each set of ridge shape taking device combinations is adjusted to ensure that its testing length is not less than the length of the ridge to be tested.

[0022] S2. Install the two assembled rectangular frames with the ridge-shaped shaper combination into the two assembly spaces of the I-shaped frame respectively, and keep the locking component between the second guide rail and the fourth guide rail in an unlocked state, so that the position of the first slider nut in the fourth guide rail and the included angle between the second guide rail and the fourth guide rail can be adjusted.

[0023] S3. Place the entire crop ridge detector over the ridge to be detected. By adjusting the relative positions of the two rectangular frames and the I-shaped frame, the two rectangular frames are attached to the sides of the ridge, while the I-shaped frame is flat against the top surface of the ridge. The shape takers in the two ridge shape takers are respectively fitted to the bottom of the side of the ridge to take the shape.

[0024] S4. After completing the posture adjustment in S3, adjust the locking component to lock the second guide rail and the fourth guide rail, so that the position of the first slider nut in the fourth guide rail and the included angle between the second guide rail and the fourth guide rail are locked. Then, remove the entire crop ridge detector from the ridge body and measure the size parameters of the ridge detection space formed by the two rectangular frames and the I-shaped frame to complete the crop ridge detection.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] This invention provides a modular, rapid assembly device to improve ridge shape detection equipment. It allows adjustment of the longitudinal section's height, top length, bottom length, and waist length to adapt to different ridge shapes, and also allows flexible adjustment of the detected ridge length. This invention enables accurate detection and shape acquisition of ridges for different crops in different regions, improving the accuracy of automatic ridge monitoring systems.

Detailed Implementation

[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Technical features in the various embodiments of the present invention can be combined accordingly without mutual conflict.

[0039] In the description of this invention, it should be understood that when an element is considered to be "connected" to another element, it can be a direct connection to the other element or an indirect connection, i.e., there is an intermediate element. Conversely, when an element is said to be "directly" connected to another element, there is no intermediate element.

[0040] In the description of this invention, it should be understood that the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0041] like Figure 1 As shown, in a preferred embodiment of the present invention, a crop ridge shape detector is provided. Its main components include an I-shaped frame 1, two rectangular frames 17, and a ridge shape measuring device assembly 2. There is one I-shaped frame 1 and two rectangular frames 17. The I-shaped frame 1 and the two rectangular frames 17 are assembled to form the main body of the ridge shape detector, and the remaining components are attached to this main body. The ridge shape detector main body can be adjusted to fit the ridge body, thereby measuring various cross-sectional dimensions of the ridge. Each of the two rectangular frames 17 is equipped with a set of ridge shape measuring device assemblies 2 for measuring the shape of the bottom side of the ridge body. The specific structure and shape of the I-shaped frame 1, the two rectangular frames 17, and the ridge shape measuring device assembly 2 are described in detail below.

[0042] like Figure 2 As shown, the main body of the ridge detector is assembled from two rectangular frames 17 on both sides of an I-shaped frame 1. The two rectangular frames 17 are used to fit the two sides of the ridge, while the I-shaped frame 1 fits the top surface of the ridge. Each rectangular frame 17 is connected by two parallel first guide rails 9 and two parallel second guide rails 14. Generally, when fitting the ridge, the two second guide rails 14 are arranged diagonally, while the two first guide rails 9 are arranged laterally. Adjacent first guide rails 9 and second guide rails 14 can be detachably fixed together by angle brackets 4, so as to facilitate disassembly and assembly when adjustment or replacement is required.

[0043] The I-shaped frame 1 is formed by connecting two parallel third guide rails 16 via a fourth guide rail 18. Adjacent third guide rails 16 and fourth guide rails 18 can also be detachably fixed using angle brackets 4 for easy assembly and disassembly when adjustment or replacement is needed. The I-shaped frame 1 is divided into two open assembly spaces by the fourth guide rail 18. Two rectangular frames 17 are respectively installed in the two assembly spaces of the I-shaped frame 1. Each rectangular frame 17 is assembled onto the two fourth guide rails 18 on both sides of its assembly space via second guide rails 14 on both sides. That is, the assembly position of the same rectangular frame 17 with the two fourth guide rails 18 is on the same side of the third guide rail 16, while the assembly positions of different rectangular frames 17 with the two fourth guide rails 18 are on different sides of the third guide rail 16.

[0044] Two rectangular frames 17 and an I-shaped frame 1 together enclose a ridge-shaped detection space with an open bottom and a trapezoidal cross-section. In actual use, the longitudinal cross-sectional shape of this ridge-shaped detection space should be a trapezoidal shape with no bottom and a top, basically consistent with the longitudinal cross-section of the ridge. However, since the longitudinal cross-sectional shape of the ridge is not fixed, the shape of the aforementioned ridge-shaped detection space should also be adjustable.

[0045] After the two rectangular frames 17 and the I-shaped frame 1 are assembled, the two fourth guide rails 18 are assembled with the four second guide rails 14, thus forming four pairs of second guide rails 14 and fourth guide rails 18 in an assembled relationship. To meet the requirement that the shape of the aforementioned ridge-shaped detection space can be adjusted, each pair of second guide rails 14 and fourth guide rails 18 in an adjustable manner is locked together by a locking assembly. This adjustable locking means that the positional relationship between the second guide rails 14 and fourth guide rails 18 can be adjusted, but after adjustment, it can be locked so that it cannot move or rotate relative to each other. Furthermore, before the second guide rails 14 and fourth guide rails 18 are locked, there are two permissible adjustment dimensions, referred to as the first adjustment dimension and the second adjustment dimension. The first adjustment dimension is the fixed position of the fourth guide rail 18 on the second guide rail 14, and the second adjustment dimension is the angle between the fourth guide rail 18 and the second guide rail 14. Therefore, before they are locked, the fixed position of the fourth guide rail 18 on the second guide rail 14 can be adjusted as needed, and the angle between the fourth guide rail 18 and the second guide rail 14 can also be adjusted as needed. Adjusting the angle between the fourth guide rail 18 and the second guide rail 14 changes the slope of the hypotenuse of the longitudinal section of the ridge detection space, allowing it to conform to the side of the ridge. Adjusting the fixed position of the fourth guide rail 18 on the second guide rail 14 changes the height and top width of the longitudinal section of the ridge detection space. With these adjustments, the ridge detection device can adapt to different ridge shapes (height, top length, bottom length, and waist length), enabling accurate detection and shape taking of ridges for different crops in different regions.

[0046] The aforementioned locking component can be implemented using any mechanism capable of having a first adjustment dimension and a second adjustment dimension. In embodiments of the present invention, such as... Figure 4 As shown, an enlarged schematic diagram of the G region where the locking component is located is as follows. Figure 5 Each pair of second guide rails 14 and fourth guide rails 18 forming an assembly relationship includes a first bolt and nut connector, a second bolt and nut connector, and a positioning plate 7. The surface of the fourth guide rail 18 needs to have a groove along the guide rail direction. In this embodiment, the aforementioned grooved fourth guide rail 18 can be implemented using a profile with grooves on all four sides, and its cross-sectional shape is as follows. Figure 3 As shown. Similarly, the first guide rail 9, the second guide rail 14, and the third guide rail 16 can also use this type of profile with grooves on all four sides. With grooves on each guide rail, components such as slider nuts and T-bolts can be easily installed to achieve the required adjustment function. The first bolt and nut connector includes a first slider nut 5 and a first self-locking bolt 6. The first slider nut 5 is installed in the groove on the surface of the fourth guide rail 18 and forms a sliding fit. Moreover, as... Figure 6As shown, the second guide rail 14 also needs to have multiple elongated holes along the guide rail direction. The first self-locking bolt 6 passes through the elongated holes, passes through the second guide rail 14, and is screwed into the first slider nut 5. When the first self-locking bolt 6 and the first slider nut 5 are tightened, the included angle between the second guide rail 14 and the fourth guide rail 18 can be freely adjusted. At the same time, the assembly position between the second guide rail 14 and the fourth guide rail 18 can be freely adjusted through the sliding space provided by the elongated holes. After the position and included angle are adjusted, the first self-locking bolt 6 and the first slider nut 5 can be tightened to lock the position and included angle between the second guide rail 14 and the fourth guide rail 18. Of course, theoretically, tightening the first self-locking bolt 6 and the first slider nut 5 can achieve the locking between the second guide rail 14 and the fourth guide rail 18, but in practice, this locked state is still prone to slippage. Therefore, it is necessary to use the second bolt and nut connector and the positioning plate 7 for auxiliary fixation. The second bolt and nut connector includes a nut 8 and a T-bolt 10. The bolt head of the T-bolt 10 is installed in a groove on the surface of the fourth guide rail 18, forming a sliding fit. A through hole is provided on the positioning plate 7, and the bolt body of the T-bolt 10 passes through the positioning plate 7 and forms a threaded fit with the nut 8. After the position and angle between the second guide rail 14 and the fourth guide rail 18 are adjusted to the correct position, the positioning plate 7 can be moved to the intersection of the two guide rails while keeping the T-bolt 10 and nut 8 loose. This allows the positioning plate 7 to translate along the fourth guide rail 18 and be inserted horizontally into the angle between the second guide rail 14 and the fourth guide rail 18. Then, the T-bolt 10 and nut 8 are tightened. Thus, under the action of the positioning plate 7 inserted into the angle, the angle between the two guide rails can be limited from further widening. When this crop ridge detector is used, it is placed downwards above the ridge, so the maximum angle between the two guide rails can be limited to the two rectangular frames 17 fitting against the sides of the ridge. When removing the crop ridge detector, even if the two guide rails become loose and rotate, causing the included angle to change, it is only necessary to bend the two rectangular frames 17 outwards again until the maximum included angle is reached.

[0047] In addition, during ridge shape detection, it is also necessary to detect the shape of the ridge's sides. Therefore, this invention requires the installation of a ridge shaper assembly 2 on the first guide rail 9 at the bottom of each rectangular frame 17 via a detachable connector. Each ridge shaper assembly 2 contains multiple shapers, which are continuously installed along the extension direction of the first guide rail 9 for shape measurement of the bottom side of the ridge. The shaper is prior art, consisting of a series of closely arranged symmetrical strips and a shape-fixing lock. Irregular shapes are measured by the extension and retraction of the symmetrical strips, and the shape is fixed by locking it with the shape-fixing lock. Any existing commercially available product can be used as the shaper.

[0048] In embodiments of the present invention, since the ridges to be detected have different lengths, the entire crop ridge detector also needs to be able to flexibly adjust the detection length. This requires ensuring that the lengths of the I-shaped frame 1, the two rectangular frames 17, and the ridge shape extractor assembly 2 can all be adjusted.

[0049] For the I-shaped frame 1 and the rectangular frame 17, since the guide rails used therein are all made of profiles with grooves on four sides, the third guide rail 16 and the first guide rail 9 can both be assembled by multi-segment splicing. In the embodiments of the present invention, such as Figure 7 As shown, adjacent sections of the third guide rail 16 and the first guide rail 9 are fixed together by a slotted connector 11 and a locking screw 12. Screw holes are drilled on both sides of the joint between the adjacent sections. A slotted connector 11 with two holes is then laid across the joint. The holes on the slotted connector 11 align with the screw holes on the guide rail sections, and the locking screw 12 is screwed in to lock the connection. Thus, the lengths of the third guide rail 16 and the first guide rail 9 can be flexibly adjusted according to the length of the detection ridge, thereby changing the lengths of the I-shaped frame 1 and the rectangular frame 17.

[0050] Furthermore, for the ridge-shaped shaper assembly 2, rapid length adjustment can be achieved by setting up connectable shapers and detachable connectors. In an embodiment of the present invention, the detachable connector includes multiple sets of hanging ears 3 and quick clamps 15. In the ridge-shaped shaper assembly 2, a set of hanging ears 3 and quick clamps 15 are provided between each pair of adjacent shapers for installation. The hanging ears 3 and quick clamps 15 are both fixed on the first guide rail 9 at the bottom of the rectangular frame 17.

[0051] like Figure 8 As shown, an enlarged view of part J is as follows. Figure 9 The hanging ear 3 is divided into a U-shaped groove section and a fixing section. The fixing section is fixed to the first guide rail 9, while the U-shaped groove section extends out of the first guide rail 9 to fix the shape extractor. The splicing position of two adjacent shape extractors passes through the U-shaped groove. After the free end of the U-shaped groove of the hanging ear 3 is tightened by the quick clamp 15, the shape extractor can be pressed onto the first guide rail 9 for fixation. The quick clamp 15 is existing technology, and there are many commercially available products. Figure 10As shown, the shapers in the ridge-shaped shaper assembly 2 all have tongue-and-groove joints on both sides, allowing adjacent shapers to be paired and connected. Each shaper has a trapezoidal groove and a convex groove at one end, allowing for the selection of different numbers of shapers for continuous splicing according to actual length requirements. A detachable connector consisting of a hanging lug 3 and a quick clamp 15 is provided at the splicing position to achieve fixed installation with the first guide rail 9. Furthermore, to facilitate adjustment of the mounting positions of the hanging lug 3 and the quick clamp 15 on the first guide rail 9, the first guide rail 9 also uses a profile with grooves along the guide rail direction on its surface. The hanging lug 3 is adjustablely fixed by a set of second self-locking bolts 13 and a second sliding nut 19. The second sliding nut 19 is installed in the groove on the surface of the first guide rail 9 and forms a sliding fit. The second self-locking bolt 13 passes through the hanging lug 3 and is screwed into the second sliding nut 19. When the second self-locking bolt 13 and the second slider nut 19 are loosened, the position of the second slider nut 19 can be flexibly adjusted, thereby changing the position of the hanging ear 3. Once adjusted to the correct position, the second self-locking bolt 13 and the second slider nut 19 can be locked.

[0052] In another embodiment of the present invention, based on the above... Figures 1-10 The crop ridge shape detector shown further provides a method for detecting crop ridge shape, the specific steps of which are as follows:

[0053] S1. Based on the length of the ridge to be tested, guide rail segments of different lengths are spliced ​​together to ensure that the lengths of the third guide rail 16 and the first guide rail 9 in the I-shaped frame 1 and the rectangular frame 17 are not less than the length of the ridge to be tested. At the same time, a set of ridge shape taking device combination 2 is installed on the first guide rail 9 at the bottom of the two rectangular frames 17, and the number of shape taking devices in each set of ridge shape taking device combination 2 is adjusted to ensure that its testing length is not less than the length of the ridge to be tested.

[0054] S2. Install the two assembled rectangular frames 17 with the ridge-shaped shaper combination 2 into the two assembly spaces of the I-shaped frame 1 respectively, and keep the locking component between the second guide rail 14 and the fourth guide rail 18 in an unlocked state, so that the position of the first slider nut 5 in the fourth guide rail 18 and the included angle between the second guide rail 14 and the fourth guide rail 18 are adjustable.

[0055] S3. Place the entire crop ridge detector over the ridge to be detected. By adjusting the relative positions of the two rectangular frames 17 and the I-shaped frame 1, the two rectangular frames 17 are attached to the sides of the ridge, while the I-shaped frame 1 is flat against the top surface of the ridge. Apply pressure to the shape takers in the two ridge shape taker combinations 2 so that they fit against the bottom of the side of the ridge to take the shape, thereby completing the posture adjustment.

[0056] S4. After completing the posture adjustment in S3, adjust the locking component to lock the second guide rail 14 and the fourth guide rail 18, so that the position of the first slider nut 5 in the fourth guide rail 18 and the included angle between the second guide rail 14 and the fourth guide rail 18 are locked. Then, remove the entire crop ridge detector from the ridge body and measure the size parameters of the ridge detection space formed by the two rectangular frames 17 and the I-shaped frame 1 to complete the crop ridge detection.

[0057] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, all technical solutions obtained through equivalent substitution or transformation fall within the protection scope of the present invention.

4. The crop ridge detector as described in claim 1, characterized in that, The guide rails used in the I-shaped frame (1) and the rectangular frame (17) are all made of profiles with grooves on all four sides.

5. The crop ridge detector as described in claim 1, characterized in that, Both the third guide rail (16) and the first guide rail (9) are assembled using a multi-segment splicing method.

6. The crop ridge detector as described in claim 5, characterized in that, The adjacent sections of the third guide rail (16) and the first guide rail (9) are fixed together by a slotted connector (11) and a locking screw (12).

7. The crop ridge detector as described in claim 1, characterized in that, In the ridge-shaped shaper assembly (2), each shaper has a tongue and groove joint on both sides, and adjacent shapers are paired and connected through the tongue and groove joint.

8. A method for detecting crop ridge shape using the crop ridge shape detector as described in claim 5, characterized in that, include: S1. Based on the length of the ridge to be tested, guide rail segments of different lengths are spliced ​​together so that the lengths of the third guide rail (16) and the first guide rail (9) in the I-shaped frame (1) and the rectangular frame (17) are not less than the length of the ridge to be tested; at the same time, a set of ridge shape taking device assembly (2) is installed on the first guide rail (9) at the bottom of the two rectangular frames (17), and each set of ridge shape taking device assembly (2) is also adjusted by adjusting the number of taking devices to ensure that its testing length is not less than the length of the ridge to be tested; S2. Install the two assembled rectangular frames (17) with the ridge-shaped shaper assembly (2) into the two assembly spaces of the I-shaped frame (1), and keep the locking assembly between the second guide rail (14) and the fourth guide rail (18) in an unlocked state, so that the position of the first slider nut (5) in the fourth guide rail (18) and the included angle between the second guide rail (14) and the fourth guide rail (18) are adjustable. S3. Cover the ridge detector with the whole crop and place it on the ridge to be detected. By adjusting the relative positions of the two rectangular frames (17) and the I-shaped frame (1), the two rectangular frames (17) are attached to the two sides of the ridge, while the I-shaped frame (1) is attached to the top surface of the ridge. The shapers in the two ridge shapers combination (2) fit the bottom of the side of the ridge to take the shape. S4. After completing the posture adjustment in S3, adjust the locking component to lock the second guide rail (14) and the fourth guide rail (18), so that the position of the first slider nut (5) in the fourth guide rail (18) and the included angle between the second guide rail (14) and the fourth guide rail (18) are locked. Then, remove the entire crop ridge detector from the ridge body and measure the dimensional parameters of the ridge detection space formed by the two rectangular frames (17) and the I-shaped frame (1) to complete the crop ridge detection.
