Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0023] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] Example

[0025] like Figure 1-Figure 7 As shown, an oat field test row drawing device comprises: a cart 1, a handle 101 installed on one side of the outer end of the cart 1, a support frame 102 installed on both sides of the bottom end of the cart 1, a connecting rod 2 installed on the outer end of the cart 1 away from the handle 101, support rods 3 installed on both sides of the outer ends of the connecting rod 2, and a row drawing component arranged on the top of the support rod 3, which is used for marking the test planting area of ​​oat field row drawing. The row drawing component comprises: a lime box 4, a feed pipe 401, a sealing cover 402, a discharge square pipe 403 and a solenoid valve 404. The row drawing component can be used to quickly draw rows in the field, solving the problems of traditional manual wiring, wire fixing and storage troubles. There is no need to use marking lines to assist use, thereby improving the efficiency of row drawing work, and there is no need to grab lime by hand to avoid dirtying the hands.

[0026] Among them, a fixed L-shaped block 301 is installed on one side of the top of the support rod 3, a movable L-shaped block 302 is provided on one side of the fixed L-shaped block 301, a slider a303 is installed on the bottom of the movable L-shaped block 302, a slide groove a304 is opened on one side of the top of the support rod 3 for use with the slider a303, and a fixing screw hole a305 is opened on the top of the slider a303 and the bottom end of the inner part of the slide groove a304.

[0027] When the ash box 4 is in use, the movable L-shaped block 302 on one side of the fixed L-shaped block 301 is first pulled apart to distance the movable L-shaped block 302 from the fixed L-shaped block 301. At this time, the ash box 4 is placed on the support rod 3 and pushed toward the fixed L-shaped block 301. When the ash box 4 and the fixed L-shaped block 301 are fitted together, the top of the fixed L-shaped block 301 is stuck with the top of the ash box 4. After one side of the ash box 4 is fitted and fixed to the fixed L-shaped block 301, the movable L-shaped block 302 is pushed to move toward the fixed L-shaped block 301, that is, the slider a303 at the bottom of the movable L-shaped block 302 slides in the slide groove a304 at the top of the support rod 3. The movable L-shaped block 302 and the other side of the ash box 4 are arranged so that the movable L-shaped block 302 and the other side of the ash box 4 fit each other. At this time, the top of the movable L-shaped block 302 will be stuck with the top of the ash box 4, and after the slider a303 slides to the position in the slide groove a304, the top of the slider a303 and the fixing screw hole a305 at the bottom end of the slide groove a304 will dock with each other, and the bolts can be screwed into the fixing screw holes a305 and tightened, thereby fixing the slider a303 in the slide groove a304, and the ash box 4 is clamped and fixed on the support rod 3 by the movable L-shaped block 302 and the fixed L-shaped block 301 for use. After the two ash boxes 4 are installed on the support rod 3, the two ash boxes 4 are placed symmetrically.

[0028] Among them, two symmetrical ash boxes 4 are installed on the top of the support rod 3, a feed pipe 401 is installed on one side of the top of the ash box 4, a sealing cover 402 is threadedly connected to the top of the feed pipe 401, and a discharge square pipe 403 is installed on one side of the bottom of the ash box 4, and a solenoid valve 404 is installed on the discharge square pipe 403.

[0029] When drawing rows in the field, the sealing cover 402 on the top of the feed pipe 401 is unscrewed and opened, and the hopper is inserted into the feed pipe 401. The ash powder is scooped from the ash bag with a spoon, and the ash powder in the spoon is poured into the hopper, and then poured into the ash box 4 through the feed pipe 401 for storage, and then the sealing cover 402 is tightened on the top of the feed pipe 401. Since the bottom of the cart 1 is provided with moving wheels, the handle 101 is grasped to lift the cart 1, and the moving wheels can drive the cart 1 to move in the field, and the cart 1 is moved to the test planting area. In the field, after the two lime boxes 4 are fixedly installed, the distance between the discharge square tubes 403 at the bottom of the lime boxes 4 is 1M. When the cart 1 is pushed to drive the lime box 4 to move, the solenoid valve 404 is started to open, and the lime powder stored in the lime box 4 is discharged into the field through the discharge square tube 403. The cart 1 is pushed along a straight line, and the distance between the discharge square tubes 403 is 1M, so that two white marking lines with a spacing of 1M can be drawn in the field, thereby forming a marked experimental planting area, and the two white marking lines are horizontal.

[0030] After drawing, close the solenoid valve 404 and turn the cart 1 around. Since the solenoid valves 404 on the discharge square tubes 403 on both sides can be started and closed separately, just start the solenoid valve 404 on one side and open it. Draw a longitudinal white marking line at one end of the two white marking lines. After drawing one end, draw a longitudinal white marking line at the other end of the two white marking lines, so that the marked experimental planting area is closed. The rows can be drawn quickly in the field, solving the problems of traditional manual wiring, wire fixing and storage. There is no need to use marking lines to assist in use, which improves the efficiency of row drawing and there is no need to grab white ash with hands to avoid getting hands dirty.

[0031] Among them, the cart 1 is arranged in a triangular structure on the side facing the handle 101. When the cart 1 drives the lime box 4 and the discharge square tube 403 to move, the cart 1 is pushed forward by grasping the handle 101, and the cart 1 is arranged in a triangular structure towards the handle 101, so that the field of view on the rear side of the cart 1 is wider, and the trajectory of the lime powder in the field can be clearly seen, so that the solenoid valve 404 can be controlled to start and close through the controller 5 on the handle 101 to avoid waste of lime powder.

[0032] Among them, a controller 5 is installed on the handle 101, and a start button 501 is provided on the controller 5. A close button 502 is provided on one side of the start button 501. A battery 6 is fixedly installed on one side of the bottom of the cart 1 by bolts, and a charging port is provided on the outside of the battery 6. The controller 5 is connected to the battery 6 and the solenoid valve 404 through wires respectively.

[0033] When the solenoid valve 404 and the controller 5 are in use, the controller 5 is connected to the battery 6 and the solenoid valve 404 respectively through wires, and the solenoid valve 404 and the controller 5 are powered by the battery 6. The solenoid valve 404 can be started and closed by the start button 501 and the close button 502 on the controller 5. Since two controllers 5 are provided on the handle 101, the start and close of the solenoid valve 404 on the discharge square tube 403 can be controlled separately, so that the single-sided discharge of the lime powder can be realized, and the control procedures involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the utility model.

[0034] Among them, a slider b306 is installed at one end of the support rod 3, a fixing screw hole b307 is opened on one side of the slider b306, two sliding grooves b7 are opened on the side of the connecting rod 2 facing the support rod 3, the slider b306 is slidably connected with the sliding grooves b7, and limiting screw holes a701 are opened on the outer sides of the two sliding grooves b7, and limiting screw holes b702 are opened on the inner sides of the two sliding grooves b7.

[0035] When the support rod 3 is installed on the connecting rod 2, the slider b306 at one end of the support rod 3 is inserted into the slide groove b7 of the connecting rod 2. At this time, the fixing screw hole b307 on the slider b306 is docked with the limiting screw hole a701 outside the slide groove b7. The screw is screwed from the fixing screw hole b307 into the limiting screw hole a701 and tightened to fix the slider b306 in the slide groove b7. The support rod 3 is then firmly installed on the connecting rod 2 for use, and the support rod 3 on the other side is also installed on the other side of the connecting rod 2 in the same way as the above operation. When the two ash boxes 4 are respectively installed on the support rod 3, the distance between the bottom discharge square tubes 403 of the two ash boxes 4 is exactly 1M.

[0036] If it is necessary to adjust the spacing between the discharge square tubes 403 to 50CM, loosen and remove the screw from the fixing screw hole b307 and the limiting screw hole a701, push the support rod 3 to drive the slider b306 to move to the inside of the slide groove b7, when the fixing screw hole b307 on the slider b306 is docked with the limiting screw hole b702 inside the slide groove b7, screw the screw from the fixing screw hole b307 into the limiting screw hole b702 and tighten it. After the support rod 3 adjusts its position, fix the slider b306 in the slide groove b7. At this time, the two lime boxes 4 move closer to each other, that is, the spacing between the discharge square tubes 403 at the bottom of the two lime boxes 4 is shortened, and the original spacing of 1M is adjusted to 50CM. Two white marking lines with a spacing of 50CM can be drawn in the field, and row markings can be drawn according to the size of the experimental planting area to achieve the purpose of convenient use.

[0037] A material guide block 8 with an oblique arc structure is installed at one side of the interior of the lime box 4, and the oblique arc of the material guide block 8 faces the position of the discharge square pipe 403.

[0038] When adding lime powder into the lime box 4, the lime powder falling into the lime box 4 will slide toward the discharge square tube 403 through the guide block 8 with an oblique arc structure, making it easy to discharge the lime powder in the lime box 4 into the discharge square tube 403 for discharge and use.

[0039] Working principle:

[0040] When drawing rows in the field, the sealing cover 402 on the top of the feed pipe 401 is unscrewed and opened, and the hopper is inserted into the feed pipe 401. The ash powder is scooped from the ash bag with a spoon, and the ash powder in the spoon is poured into the hopper, and then poured into the ash box 4 through the feed pipe 401 for storage, and then the sealing cover 402 is tightened on the top of the feed pipe 401. Since the bottom of the cart 1 is provided with moving wheels, the handle 101 is grasped to lift the cart 1, and the moving wheels can drive the cart 1 to move in the field, and the cart 1 is moved to the test planting area. In the field, after the two lime boxes 4 are fixedly installed, the distance between the discharge square tubes 403 at the bottom of the lime boxes 4 is 1M. When the cart 1 is pushed to drive the lime box 4 to move, the solenoid valve 404 is started to open, and the lime powder stored in the lime box 4 is discharged into the field through the discharge square tube 403. The cart 1 is pushed along a straight line, and the distance between the discharge square tubes 403 is 1M, so that two white marking lines with a spacing of 1M can be drawn in the field, thereby forming a marked experimental planting area, and the two white marking lines are horizontal.

[0041] After drawing, close the solenoid valve 404 and turn the cart 1 around. Since the solenoid valves 404 on the discharge square tubes 403 on both sides can be started and closed separately, just start the solenoid valve 404 on one side and open it. Draw a longitudinal white marking line at one end of the two white marking lines. After drawing one end, draw a longitudinal white marking line at the other end of the two white marking lines, so that the marked experimental planting area is closed. The rows can be drawn quickly in the field, solving the problems of traditional manual wiring, wire fixing and storage. There is no need to use marking lines to assist in use, which improves the efficiency of row drawing and there is no need to grab white ash with hands to avoid getting hands dirty.
