Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, specifically relating to a portable, adjustable plant and row spacing rapid positioning device for crops. Background Technology

[0002] In agricultural planting, especially in experimental fields or cultivation scenarios requiring precise control of row and plant spacing, ensuring plants receive adequate growing space and light resources is crucial. For a long time, the industry has commonly used a method of inserting fixed bamboo poles at both ends of the target field as benchmarks. Then, ropes or cords are wrapped around and tightened between the two bamboo poles to delineate a pre-defined row direction baseline. Workers then manually mark the specific location of each planting hole along this baseline, according to the required spacing between individual plants. Subsequent planting operations strictly follow these marked points for sowing or transplanting, thus achieving basic row and plant spacing control to meet the differentiated planting density requirements of different crops or experimental treatments. For mature crops such as rice, the agricultural planting environment uses fixed spacing and row spacing, without adjustment of plant and row spacing. For experimental crop variety control fields, row and plant spacing are adjusted according to different planting density requirements.

[0003] The traditional method requires a lot of manual time to repeatedly complete steps such as benchmark setting, point marking, and planting calibration, which seriously restricts planting efficiency. Furthermore, every time the plot is changed or the density is adjusted, the poles and ropes must be re-inserted and marked, resulting in poor reusability of the device. Summary of the Invention

[0004] The technical problem this invention aims to solve is that inserting fixed bamboo poles at both ends of the target field as benchmark points, and then repeatedly completing the steps of benchmark setting, point marking, and planting calibration by winding and tightening ropes or cords between the two bamboo poles, consumes a lot of manual time and severely restricts planting efficiency. In response to the shortcomings of the existing technology, this invention provides a portable, adjustable row and plant spacing rapid positioning device for crops.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The system includes: at least two sets of fixing rods, and row spacing control components mounted on the two sets of fixing rods; each set of row spacing control components is equipped with an adjustable plant spacing control component; each row spacing control component includes a graduated longitudinal rod with a groove in the middle; an adjusting frame is slidably mounted in the groove, and the plant spacing control component is mounted on the adjusting frame; each plant spacing control component includes a rope frame with a fixing groove, and a clamping plate is rotatably mounted in the fixing groove; the side wall of the rope frame has a threaded groove communicating with the fixing groove, and a rotating screw is threadedly connected in the threaded groove; the rotating screw is used to push the clamping plate to clamp or release the plant spacing rope; the plant spacing rope is equipped with an adjustable and fixed positioning clip.

[0006] Furthermore, both ends of the adjustment frame extend into sliding grooves, one end of which is connected to the plant spacing control component and the moving wheel, and the other end is provided with a retaining groove; a retaining frame is rotatably installed in the retaining groove, and the arc-shaped head of the retaining frame is used to rotate and tighten the longitudinal rod for locking.

[0007] Furthermore, the curvature of the arc-shaped head of the abutment matches the curvature of the outer wall of the longitudinal bar, and the head is made of rubber.

[0008] Furthermore, the scale markings on the longitudinal rod are arranged longitudinally along the slide groove, and the surface of the plant spacing rope is provided with equidistant scale lines with a scale accuracy of 1mm.

[0009] Furthermore, both ends of the longitudinal rod are fixedly connected to a fixing sleeve, and a handle screw is installed on each of the two sets of fixing sleeves; the fixing pin is installed inside one set of fixing sleeves, and a ground pin is installed inside the other set of fixing sleeves; the threaded ends of the two sets of handle screws are respectively locked against the outer walls of the fixing pin and the ground pin.

[0010] Furthermore, the abutment includes a handle rotatably disposed inside the abutment, the handle is connected to a protruding bracket via a return spring, a guide groove is provided in the middle of the handle, and the protruding bracket is slidably disposed on the handle via the guide groove; a boss is provided at the top of the protruding bracket, and the boss is engaged with the abutment via a return spring.

[0011] Furthermore, a rope is fixedly mounted on the surface of one of the sets of fixed rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This system optimizes the traditional manual rope-pulling positioning method, improving the efficiency and precision of farmland planting. Through a graduated vertical rod and sliding groove structure, combined with a freely sliding adjustment frame, stepless and rapid adjustment of row spacing is achieved. Operators only need to slide the component to the target position according to the graduated markings to accurately set the row spacing, avoiding the tedious process of repeatedly inserting rods and pulling ropes.

[0013] 2. Regarding plant spacing control, a mechanical structure using a rotating screw to drive the clamping plate is adopted. Through a simple rotation operation, the plant spacing rope can be clamped or released instantly. Combined with the scale markings on the rope, this ensures precise control of the spacing between individual plants and effectively avoids the cumulative errors of manual point-by-point marking.

[0014] 3. To ensure the stability of field operations, the device is equipped with a double locking mechanism: the adjustment frame is tightly fitted with the longitudinal rod through the arc-shaped friction surface of the abutment, and is further reinforced by the lever-linked convex head frame of the lever, forming a double insurance against displacement, preventing the adjustment frame from moving accidentally, and ensuring that the positioning benchmark remains reliable in complex terrain.

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] Example 1: See Figure 1-7 This embodiment provides a portable, adjustable row and plant spacing rapid positioning device for crops, which includes: At least two sets of fixing rods 1, and row spacing control components 2 installed on the two sets of fixing rods 1; each set of row spacing control components 2 is equipped with an adjustable plant spacing control component 3; The row spacing control component 2 includes a graduated vertical rod 21 with a groove 22 in the middle. The vertical rod 21 of the row spacing control component 2 is vertically rigidly connected to the fixed rod 1 through the end fixing sleeve 5, forming a row reference frame. An adjustment frame 23 is slidably provided inside the chute 22, and the plant spacing control component 3 is installed on the adjustment frame 23; The plant spacing control component 3 includes a rope frame 31, a fixing groove 32 on the rope frame 31, and a clamping plate 33 rotatably installed in the fixing groove 32; the rope frame 31 of the plant spacing control component 3 is welded to one side of the adjusting frame 23. The side wall of the rope frame 31 is provided with a threaded groove 34 that communicates with the fixing groove 32, and a rotating screw 35 is threadedly connected in the threaded groove 34. The rotating handle screw 35 is used to push the clamping plate 33 to clamp or release the plant spacing rope 4. The plant spacing rope 4 is provided with an adjustable and fixed positioning clip 41. When the rotating handle screw 35 is rotated, its front end pushes the clamping plate 33, so that the clamping plate 33 rotates in the fixing groove 32 with the rotating shaft connected at the end as the center, so that the clamping plate 33 and the inner wall of the rope frame 31 form a clamping of the plant spacing rope 4.

[0020] See Figure 2-4Both ends of the adjusting frame 23 extend from the sliding grooves 22 to form symmetrical cantilever arms. The first cantilever at one end is connected to the plant spacing control component 3 and the moving wheel 24. The moving wheel 24 is mounted on the first cantilever via a pivot pin, allowing the moving wheel 24 to move along one side of the longitudinal rod. The second cantilever at the other end has a rectangular abutment groove 25. An abutment 26 is rotatably mounted in the abutment groove 25. The arc-shaped head 27 of the abutment 26 is used to rotate and lock the longitudinal rod 21. The abutment 26 is hinged in the abutment groove 25 via a transverse pivot. The rotation trajectory of the arc-shaped head 27 of the abutment 26 matches the outer contour of the longitudinal rod 21. One side of the sliding groove 22 on the outer contour of the longitudinal rod 21 has an arc-shaped surface corresponding to the abutment 26. When the abutment 26 is pressed down, the arc-shaped head 27 rotates around the pivot to press against the outer surface of the longitudinal rod 21. The pivot is positioned off-center from the arc-shaped head and closer to the abutment 26.

[0021] See Figure 2-4 The arc of the curved head 27 of the support frame 26 matches the curvature of the outer contour of the longitudinal bar 21, and the head is made of rubber.

[0022] See Figure 1-3 as well as Figure 6-7 The scale markings of the longitudinal rod 21 are set on the top surface of the longitudinal rod 21 and are arranged longitudinally along the length of the slide groove 22. The plant spacing rope 4 has equidistant scale lines 42 on its surface. The equidistant scale lines 42 on the surface of the plant spacing rope 4 are made of plastic rope and are repeatedly dipped to form a transparent protective layer. The scale accuracy is 1mm.

[0023] See Figure 1-6 Both ends of the longitudinal rod 21 are fixedly connected to a fixing sleeve 5, and a handle screw 51 is installed on each of the two sets of fixing sleeves 5; The fixed pin 1 is installed inside one set of fixed sleeves 5, and the ground pin 52 is installed inside the other set of fixed sleeves 5. The threaded ends of the two sets of handle screws 51 are respectively locked against the outer walls of the fixed pin 1 and the ground pin 52. The fixed sleeve 5 is a hollow cylindrical structure, and its inner diameter is clearance-fitted with the outer diameter of the fixed pin 1 and the ground pin 52. The handle screw 51 passes through the through hole in the side wall of the fixed sleeve 5 laterally. When the handle screw 51 is tightened clockwise, its tapered thread end radially presses against the outer surface of the pin body to generate static friction.

[0024] See Figure 1-6 The abutment 26 includes a handle 61 rotatably disposed inside the abutment 26. The handle 61 rotates through a pivot penetrating the abutment 26. The handle 61 is connected to a protruding bracket 63 via a return spring 62. The two ends of the return spring 62 are mounted on the base of the handle 61 and the protruding bracket 63. A guide groove is provided in the middle of the handle 61. The protruding bracket 63 is slidably disposed on the handle 61 via the guide groove. The top of the protruding head bracket 63 is provided with a protrusion 64, which is engaged with the abutment bracket 26 by a return spring 62; When the abutment 26 locks the longitudinal rod 21, the rotating handle 61 drives the protrusion bracket 63 to rotate and press against the longitudinal rod 21; at this time, the guide return spring 62 pushes the protrusion bracket 63 to move upward, so that the protrusion 64 is embedded in the top limiting groove of the abutment 26. When the locking of the abutment 26 and the longitudinal rod 21 is released, the protruding head 63 is pulled and the handle 61 is rotated to disengage the boss 64 from the abutment 26. The return spring 62 pulls the protruding head 63 back into the cavity of the abutment 26. The boss 64 forms a lever, and the downward pressure of the handle 61 drives the abutment 26 to rotate and release the abutment.

[0025] See Figure 6 One of the fixed pins 1 has a rope hanger 7 fixedly installed on its surface.

[0026] Work process: S1. The operation of the device begins with the establishment of the field reference: The operator attaches the fixing sleeves 5 at both ends of the longitudinal rod 21 to the fixing pin 1 and the ground pin 52 respectively, and tightens the handle screw 51 so that its conical end radially presses against the surface of the fixing pin 1 and the ground pin 52, thereby achieving horizontal rigid fixation of the longitudinal rod 21 and forming a row reference frame. At this time, the flange at the bottom of the adjusting frame 23 is embedded in the sliding groove 22 of the longitudinal rod 21, and the moving wheel 24 contacts the side of the longitudinal rod 21 to reduce frictional resistance. Then, the two fixing pins 1 and the ground pin 52 are vertically inserted into both ends of the field.

[0027] S2, Row spacing adjustment stage: Slide the adjustment bracket 23 along the slide groove 22 to the target row spacing position indicated by the scale on the top surface of the longitudinal rod 21, lift the handle 61 to drive the abutment 26 to rotate so that its rubber arc head 27 presses against the outer surface of the longitudinal rod 21 to form a preliminary friction lock.

[0028] S21. When adjusting the row spacing, push the protruding head bracket 63 upwards so that the protrusion 64 is embedded in the groove inside the abutment bracket 26 to form a lever fulcrum. Press down the handle 61 to drive the abutment bracket 26 to rotate so that its rubber arc-shaped head 27 separates from the outer surface of the longitudinal rod 21. This process only requires one person to operate, greatly reducing the time required.

[0029] S3. Plant Spacing Setting: Untie the plant spacing rope 4 from the rope hook 7, straighten it, and unfold it perpendicular to the longitudinal bar 21, placing it into the fixing groove 32. Rotate the rotating screw 35 to push the clamping plate 33 to rotate within the fixing groove 32, so that the clamping plate 33 and the inner wall of the rope frame 31 clamp the rope together. Based on the equidistant scale lines 42 formed by the dip coating on the surface of the plant spacing rope 4, lock the positioning clip 41 to the target plant spacing position.

[0030] S4. During planting, personnel sow or transplant seeds along the marked points of the positioning clips 41 on the plant spacing rope 4. If row spacing needs to be adjusted, simply release the locking mechanism 26, slide the adjusting frame 23 to the new position using the moving wheels 24, and then re-secure it. After the operation is completed, reverse the screw 51 to release the seed body, disassemble the frame of the longitudinal rod 21, loosen the screw 35 to release the plant spacing rope 4, and finally wrap the rope around the horizontal section of the rope hanger 7 to complete the storage.

[0031] Technical effects of this embodiment: 1. A systematic optimization of the traditional manual rope-pulling positioning method has been implemented, improving the efficiency and precision of farmland planting. Through a graduated vertical rod and sliding groove structure, combined with a freely sliding adjustment frame, stepless and rapid adjustment of row spacing is achieved. Operators only need to slide the component to the target position according to the graduated markings to accurately set the row spacing, avoiding the tedious process of repeatedly inserting rods and pulling ropes.

[0032] 2. Regarding plant spacing control, a mechanical structure using a rotating screw to drive the clamping plate is adopted. Through a simple rotation operation, the plant spacing rope can be clamped or released instantly. Combined with the scale markings on the rope, this ensures precise control of the spacing between individual plants and effectively avoids the cumulative errors of manual point-by-point marking.

[0033] 3. To ensure the stability of field operations, the device is equipped with a double locking mechanism: the adjustment frame is tightly fitted with the longitudinal rod through the arc-shaped friction surface of the abutment, and is further reinforced by the lever-linked convex head frame of the lever, forming a double insurance against displacement, preventing the adjustment frame from moving accidentally, and ensuring that the positioning benchmark remains reliable in complex terrain.

[0034] 4. The portability of the device has also been significantly improved. The coordinated design of the fixing sleeve and the handle screw allows for quick assembly and disassembly of the fixing rod and the ground rod. The rod body is fixed simply by tightening the handle screw, greatly reducing the preparation time for cross-plot operations. The moving wheels on the adjustment frame effectively reduce the sliding resistance of the components, facilitating continuous adjustment of the working position. In addition, the rope hanging structure added to the side wall of the fixing rod provides a neat storage solution for the plant spacing rope, avoiding rope tangling and further enhancing the reusability and portability of the equipment.
