[0043] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0044] like Figure 1-6As shown, this utility model provides an electrically driven adjustable ridging device with equal row spacing, including: a crossbeam 101, a plow 102, a linkage mechanism 103, a main beam 201, a square boss 202, a boss U-bolt 203, a longitudinal arm beam 204, a first push rod 301, a second push rod 302, a third push rod 303, a first support pin 301a, a second support pin 302a, a third support pin 303a, a first slide rail 301b, a second slide rail 302b, a third slide rail 303b, a screw 401, a fixed support 402, a first bearing 403, a second bearing 404, and a drive motor 405.

[0045] The main beam 201 is fixedly supported on the rotary tiller. One end of the longitudinal arm beam 204 is fixedly positioned at the middle of the main beam 201. A drive motor 405 is fixedly mounted at one end of the longitudinal arm beam 201. The output end of the drive motor 405 is connected to one end of the screw 401, and the other end of the screw 401 is rotatably supported on the other end of the longitudinal arm beam 204. Multiple slides are spirally formed along the circumference of the screw 401, symmetrically arranged around the middle of the screw 401. A support pin is correspondingly fitted to each slide, allowing the support pin to move relative to the slide. On the main beam 201, on both sides of the longitudinal arm beam 204, a plurality of linkage mechanisms 103 are symmetrically arranged. They are arranged longitudinally, one end of the linkage mechanism 103 is rotatably mounted on the main beam 201, and the other end is detachably connected to the plow mechanism. A plurality of push rods are symmetrically arranged on both sides of the longitudinal arm beam 204. One end of each push rod is hinged to the corresponding support pin in sequence, and the other end is hinged to the other end of the corresponding linkage mechanism in sequence.

[0046] like Figure 1 As shown, the crossbeam 101 is a square tail beam transversely placed on the square frame structure of the rotary tiller. The main beam 201 of the ridging machine is supported by square bosses 202 and U-bolts 203 symmetrically arranged on the crossbeam, allowing it to be suspended on one side of the crossbeam 101. At the middle position of the main beam 201, one end of the longitudinal arm beam 204 is fixed to the main beam 201 by two U-bolts 205. Multiple linkage mechanisms 103 are symmetrically arranged on both sides of the longitudinal arm beam 204.

[0047] In this utility model, as a preferred embodiment, the cross-sections of the main beam 201 and the longitudinal arm beam 204 are both square.

[0048] like Figure 2As shown, the linkage mechanism 103 includes: two connecting rods 1031, a first connecting plate 1032, multiple cylindrical pins 1033, and a second connecting plate 1034. The first connecting plate 1032 and the second connecting plate 1034 are arranged opposite to each other. The first connecting plate 1032 is fixedly mounted on the main beam 201 by U-bolts. On the side of the first connecting plate 1032 facing the second connecting plate 1034, two first bosses are arranged at intervals. On the side of the second connecting plate 1034 facing the first connecting plate 1032, two second bosses are arranged at intervals. The two connecting rods 1031 are arranged parallel to each other at intervals. The two ends of the connecting rods 1031 are respectively located in the first bosses and the second bosses. Cylindrical pin mounting holes are provided on both the first bosses and the second bosses. The two ends of the connecting rod 1031 are connected and constrained between the first connecting plate 1032 and the second connecting plate 1033 respectively by a rolled lug structure and a cylindrical pin 1033, and can rotate around the cylindrical pin 1033. One end of the cylindrical pin 1033 is provided with a sleeve and a locking pin to prevent it from disengaging. On the outer side of the second connecting plate 1034, a clamping plate structure for adjusting the height of the plowing mechanism is provided, with two clamping plates arranged opposite each other on one side of the second connecting plate 1034. On the clamping plates, a plurality of first mounting holes are provided along the vertical direction of the clamping plates, and the plurality of first mounting holes are spaced apart along the longitudinal direction of the clamping plates.

[0049] The tillage mechanism includes a tillage arrow 1035 and a tillage plow 102. One end of the tillage arrow 1035 has a second mounting hole that matches the first mounting hole. A fixing pin secures one end of the tillage arrow 1035 between two clamping plates. The height of the tillage arrow 1035 can be adjusted using mounting holes of different heights. Adjusting the mounting height of the tillage arrow 1035 adjusts the ridging depth of the tillage plow 102. The tillage arrow 1035 is fixedly connected to the outer end of the connecting rod mechanism 103 via a second connecting plate 1034. The tillage arrow 1035 can swing around the first connecting plate 1032 via four cylindrical pins 1033. This structure ensures that the tillage head of the tillage plow 102 always faces forward when the plow 102 wobbles to the left or right.

[0050] In this utility model, as a preferred embodiment, the drive motor 405 is a stepper motor.

[0051] In this utility model, the number of slide rails, support pins, linkage mechanisms, plowing mechanisms, and push rods is the same, all being 6.

[0052] In another embodiment, the number of slides, support pins, linkage mechanisms, plowing mechanisms, and push rods are all eight.

[0053] In another embodiment, the number of slides, support pins, linkage mechanisms, plowing mechanisms, and push rods are all 10.

[0054] like Figure 3As shown, the connecting rods 1031 of each linkage mechanism 103 are connected to the corresponding first push rod 301, second push rod 302, and third push rod 303 respectively via cylindrical pins 1033 at their other ends. The first support pin 301a, second support pin 302a, and third support pin 303a are respectively matched and disposed within the corresponding first slide rail 301b, second slide rail 302b, and third slide rail 303b, and can slide along the corresponding slide rails. One end of the first push rod 301, second push rod 302, and third push rod 303 is respectively connected to the first support pin 301a, second support pin 302a, and third support pin 303a, and can swing around them. The screw 401 is mounted on the longitudinal arm beam 204. Both ends of the screw 401 are rotatably supported by a first bearing 404 and a second bearing 403 located at both ends of the longitudinal arm beam 204. A fixed support 402 is also provided on the longitudinal arm beam 204, between the first bearing 404 and the second bearing 403. A support bearing is installed inside the fixed support 402. The outer ring of the support bearing is fixedly mounted to the fixed support 402, and the inner ring is matched and positioned in the middle of the screw 401, supporting the screw 401. The support bearing ensures that the screw 401 can rotate freely in both directions under external force. One end of the screw 401 passes through the first bearing 404 and is connected to the rotor output end of the drive motor 405, allowing the screw 401 to rotate synchronously with the forward or reverse rotation of the drive motor 405.

[0055] When the screw 401 rotates with the drive motor 405, the first slide rail 301b, the second slide rail 302b and the third slide rail 303b, which are symmetrically arranged along the center position of the screw 401, rotate synchronously with the screw 401. At the same time, they drive the first support pin 301a, the second support pin 302a and the third support pin 303a, which are arranged in each slide rail, to slide synchronously along the corresponding slide rail. Since one end of the first support pin 301a, the second support pin 302a, and the third support pin 303a is connected to the corresponding first push rod 301, second push rod 302, and third push rod 303, the end face of the push rod ensures that the support pin is always directly above the screw 401 during the sliding process with the slide rail, so as to ensure that the two ends of the push rod are always in the same horizontal plane. That is, when the first support pin 301a, the second support pin 302a, and the third support pin 303a rotate left and right with the screw 401, they can only slide forward or backward along the first slide rail 301b, the second slide rail 302b, and the third slide rail 303b. The axial distance of the sliding ensures that the plow spacing connected to the outer end (other end) of the first push rod 301, the second push rod 302, and the third push rod 303 always meets the equal spacing change.

[0056] like Figure 5As shown, the first slide rail 301b, the second slide rail 302b, and the third slide rail 303b, which are provided on the side of the screw 401, extend 360° in the circumferential direction. The lateral width of the slide rail corresponds to 120° of the circumferential side. Point O corresponds to the position of the fixed support 402. Points X, Y, and Z correspond to the initial positions of the first support pin 301a, the second support pin 302a, and the third support pin 303a in the corresponding first slide rail 301b, second slide rail 302b, and third slide rail 303b, respectively.

[0057] like Figure 3 , Figure 5 As shown, when the drive motor 405 rotates counterclockwise, it drives the screw 401 to rotate counterclockwise. The first support pin 301a, second support pin 302a, and third support pin 303a, respectively connected to one end of the first push rod 301, second push rod 302, and third push rod 303, slide along the first slide rail 301b from the initial point X to the endpoint X1, the second slide rail 302b from the initial point Y to the endpoint Y1, and the third slide rail 303b from the initial point Z to the endpoint Z. This, in turn, drives the cylindrical pins connected to the other ends of the first push rod 301, second push rod 302, and third push rod 303, as well as the plow, to move closer to the middle screw position. That is, the cylindrical pins 1033 in the three sets of linkage mechanisms 103 swing from point E to point E1, from point F to point F1, and from point G to point G1, respectively. Figure 6 As shown, this ultimately achieves equal spacing adjustment of the three sets of tillers on the right side of the longitudinal arm beam 204. Simultaneously, the three sets of push rods on the left side of the longitudinal arm beam 204 move synchronously towards the middle screw position along with the slide rails and support pins mounted on the screw 401, achieving equal spacing adjustment of the three sets of tillers on the left side.

[0058] According to the initial structural parameters of this ridging device, by setting the initial point positions of the first support pin 301a, the second support pin 302a, and the third support pin 303a on the corresponding first slide rail 301b, the second slide rail 302b, and the third slide rail 303b, the row spacing between each set of plows supported and connected at the other end of the linkage mechanism 103 is kept consistent.

[0059] Example

[0060] like Figure 6 As shown, the origin O of the coordinate system is set as the position of the fixed support 402, the intersection of the longitudinal arm beam 204 and the main beam 201 is D, the OD direction is the X-axis direction, and the position point where one end of the third push rod 303 is connected to the corresponding support pin is G, with the OG direction being the Y-axis direction. The three sets of linkage mechanisms set on the right side of the main beam 201 are arranged sequentially at points A, B, and C. In the rectangle formed by ODCG, the cylindrical pin points E, F, and G corresponding to the other ends of the first push rod 301, the second push rod 302, and the third push rod 303 are arranged sequentially on side OG.

[0061] When the drive motor 405 drives the screw 401 to rotate counterclockwise, the first support pin 301a, the second support pin 302a, and the third support pin 303a at one end of the first push rod 301, the second push rod 302, and the third push rod 303 slide along the first slide rail 301b from the initial point X to the end point X1, the second slide rail 302b from the initial point Y to the end point Y1, and the third slide rail 303b from the initial point Z to the end point Z1, respectively. The position of the cylindrical pin at the other end of the first push rod 301, the second push rod 302, and the third push rod 303 swings from point E, F, and G to point E1, F1, and G1, respectively. That is, point E1 is on the circle with point A as the center and radius AE, point F1 is on the circle with point B as the center and radius BF, and point G1 is on the circle with point C as the center and radius CG.

[0062] At this time, the motion trajectories of the first support pin 301a, second support pin 302a, and third support pin 303a corresponding to one end of the first push rod 301, the second push rod 302, and the third push rod 303 always satisfy the equation:

[0063] 1) Since point E1 lies on a circle with center A and radius AE, we can conclude that:

[0064] (xE1-AE) 2 +(yE1-OE) 2 =AE 2 ,

[0065] Where xE1 and yE1 correspond to the x and y coordinates of point E1, respectively;

[0066] Let the coordinates of point X1 be (x1, 0). From the equation (x1 - xE1)... 2 +(0-yE1) 2 =E1X1 2＝ EX 2

[0067] The final position of point X1 is: x1 = xE1 + sqrt(EX) 2 -yE1 2 )

[0068] 2) Since point F1 lies on a circle with center B and radius BF, we can conclude that:

[0069] (xF1-BF) 2 +(yF1-OF) 2 =BF 2 ,

[0070] Where xF1 and yF1 correspond to the x and y coordinates of point F1, respectively;

[0071] Let the coordinates of point Y1 be (y1, 0). From the equation (y1 - xF1)... 2+(0-yF1) 2 =FY 2

[0072] The final position of point Y1 is: y1 = xF1 + sqrt(FY) 2 -yF1 2 )

[0073] 3) Since point G1 lies on a circle with center C and radius CG, we can conclude that:

[0074] (xG1-CG) 2 +(yG1-OG) 2 =CG 2 ,

[0075] Where xG1 and yG1 correspond to the x and y coordinates of point G1, respectively;

[0076] Let the coordinates of point G1 be (g1, 0). From the equation (g1 - xG1)... 2 +(0-yG1) 2 =GZ 2 ;

[0077] The final position of point G1 is obtained as: g1 = xG1 + sqrt(GZ) 2 -yG1 2 );

[0078] Based on the actual row spacing requirements for ridged farmland, combined with Figure 6 Set the lengths of DA and OE to 260mm, AB and EF to 520mm, BC and FG to 520mm, and OD to no less than 800mm.

[0079] In the specific implementation plan, the adjustment range of the line spacing of this mechanism is set to ±20mm, that is, the length of SA is 20mm, then the length of PB is 60mm and the length of NC is 100mm to meet the adjustment requirement of reducing the line spacing by 20mm. The initial X, Y, and Z coordinates are set to (80,0), (240,0), and (400,0) respectively, in mm. It can be obtained that after the stepper motor 405 drives the screw 401 to rotate, the points X1, Y1, and Z1 after the inner end of the push rod moves are (128.14,0), (384.91,0), and (642.31,0) respectively, and the error accuracy is reduced to ±0.1mm. At this time, the first slide rail 301b, the second slide rail 302b, and the third slide rail 303b at the upper end of the screw 401 are set to meet the electric drive equal spacing adjustment requirement of this mechanism. Similarly, the first to third slide rails at the lower end of the screw 401 are also set to meet the electric drive equal spacing adjustment requirement.
