Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery and equipment, and particularly relates to a controller for the pitch and roll regulating valves of a transplanter chassis. Background Art

[0002] The terrain in hilly and mountainous areas is relatively complex. When the slope of the working plot changes, the chassis of the transplanter will pitch or roll, and the inclined chassis will no longer remain horizontal, resulting in the transplanting tool not being able to maintain plumb.

[0003] The degree of pitch or roll can be measured by the pitch angle and the roll angle. The pitch angle and the roll angle are two main factors affecting the level of the transplanter chassis. The pitch angle refers to the angle between the longitudinal axis of the transplanter chassis and the horizontal plane, and the roll angle refers to the angle between the transverse axis of the transplanter chassis and the horizontal plane.

[0004] Transplanting is an important link in the planting of many agricultural and economic crops. During the mechanized transplanting process in hilly and mountainous areas, to accurately plant the seedlings of agricultural and economic crops into the well-prepared land, it is necessary to ensure the plumbness of the transplanted seedlings. Therefore, the transplanting tool should be kept plumb as much as possible, and the chassis of the transplanter should be kept horizontal as much as possible. Summary of the Invention

A first bolt 2 is passed through the hollow controller seat 1. An installation bracket 3 is provided on the lower side of one end of the hollow controller seat 1. The pitch and roll regulating valve controller for the transplanter chassis further comprises:

[0046] A roll adjusting handle 4 is arranged on one side of the hollow controller seat 1 and is rotatably connected to the first bolt 2.

[0049] The first limiting plate 8 is symmetrically provided with a first rectangular hole 10 allowing the first guide plate 5 to pass through and a second rectangular hole 11 allowing the second guide plate 7 to pass through;

[0050] The second limiting plate 9 is symmetrically provided with a third rectangular hole 12 allowing the first guide plate 5 to pass through and a fourth rectangular hole 13 allowing the second guide plate 7 to pass through;

[0051] Cables are respectively arranged on the first guide plate 5 and the second guide plate 7. The pitch and roll regulating valve controller for the transplanter chassis is connected to the regulating valve through the cables. When the first guide plate 5 slides back and forth in the first rectangular hole 10 and the third rectangular hole 12, and the second guide plate 7 slides back and forth in the second rectangular hole 11 and the fourth rectangular hole 13, the first guide plate 5 and the second guide plate 7 trigger the regulating valve through the cables to cause the transplanter chassis to perform pitch and roll actions.

[0052] Specifically, holes allowing the first bolt 2 to pass through are provided in the middle of the roll adjusting handle 4 and the pitch adjusting handle 6. The threaded section of the first bolt 2 sequentially passes through the pitch adjusting handle 6, the hollow controller seat 1, and the roll adjusting handle 4, fixing the roll adjusting handle 4 and the pitch adjusting handle 6 on both sides of the hollow controller seat 1 respectively. The roll adjusting handle 4 and the pitch adjusting handle 6 are both rotatably connected to the first bolt 2. The upper ends of the roll adjusting handle 4 and the pitch adjusting handle 6 both protrude above the upper end of the hollow controller seat 1 for easy gripping by the operator;

[0053] The inner side of the lower part of the roll adjustment handle 4 is detachably connected to the outer end face of the first guide plate 5. The two ends of the first guide plate 5 pass through one side of the mounting frame 3 close to the roll adjustment handle 4 and are slidably connected to the mounting frame 3, so that the first guide plate 5 can move horizontally on the mounting frame 3. One end of the first guide plate 5 close to the middle of the hollow controller base 1 is connected to one end of the wire rope, and the other end of the wire rope is connected to the regulating valve;

[0054] The inner side of the lower part of the pitch adjustment handle 6 is detachably connected to the outer end face of the second guide plate 7. The two ends of the second guide plate 7 pass through one side of the mounting frame 3 close to the pitch adjustment handle 6 and are slidably connected to the mounting frame 3, so that the second guide plate 7 can move horizontally on the mounting frame 3. One end of the second guide plate 7 close to the middle of the hollow controller base 1 is connected to one end of the wire rope, and the other end of the wire rope is connected to the regulating valve;

[0055] The two ends of the first guide plate 5 respectively pass through the first rectangular hole 10 and the third rectangular hole 12, and are in sliding contact with the hole walls of the first rectangular hole 10 and the third rectangular hole 12. The two ends of the second guide plate 7 respectively pass through the second rectangular hole 11 and the fourth rectangular hole 13, and are in sliding contact with the hole walls of the second rectangular hole 11 and the fourth rectangular hole 13;

[0056] By providing the first rectangular hole 10 and the third rectangular hole 12 to limit the movement of the first guide plate 5 in the vertical direction, so that the first guide plate 5 can only move horizontally, thereby converting the rotation of the roll adjustment handle 4 into the horizontal movement of the first guide plate 5 to drive the wire rope to act;

[0057] By providing the second rectangular hole 11 and the fourth rectangular hole 13 to limit the movement of the second guide plate 7 in the vertical direction, so that the second guide plate 7 can only move horizontally, thereby converting the rotation of the pitch adjustment handle 6 into the horizontal movement of the second guide plate 7 to drive the wire rope to act.

[0058] When the lateral slope of the plot changes, the chassis of the transplanter will roll. At this time, rotate the roll adjustment handle 4 to drive the first guide plate 5 to move horizontally on the mounting frame 3. The first guide plate 5 drives the wire rope to move, causing the stroke of the wire rope to change. The wire rope triggers the regulating valve to perform a control action. The regulating valve controls the hydraulic transmission device to act, and the hydraulic transmission device drives the chassis to lift to adjust the roll degree of the chassis to make the chassis horizontal, thereby realizing the roll adjustment of the transplanter chassis;

[0059] When the longitudinal slope of the plot changes, the chassis of the transplanter will pitch. At this time, rotate the pitch adjustment handle 6 to drive the second guide plate 7 to move horizontally on the mounting frame 3. The second guide plate 7 drives the cable to move, causing the cable travel to change. The cable triggers the control action of the regulating valve, and the regulating valve controls the hydraulic transmission device to act. The hydraulic transmission device drives the chassis to lift and lower to adjust the pitch of the chassis, making the chassis level, so as to realize the pitch adjustment of the transplanter chassis;

[0060] In this embodiment, by setting the roll adjustment handle 4 and the pitch adjustment handle 6 to adjust the pitch and roll of the transplanter chassis, during the operation, according to the changes in the longitudinal and transverse slopes of the operation plot relative to the horizontal plane, the roll adjustment handle 4 and the pitch adjustment handle 6 can be rotated in time to control the pitch and roll of the transplanter chassis, keep the transplanter level, ensure the plumbness of the transplanted seedlings, and achieve the purpose of improving the growth efficiency of agricultural and economic crops in hilly and mountainous areas.

[0092] In the present application, when the chassis of the transplanter is adjusted to a suitable roll degree, the roll adjustment handle 4 is pushed to drive the first guide plate 5 to move horizontally, so that the first plunger ball head set screw 15 and the first guide plate 5 slide relative to each other. When the first plunger ball head set screw 15 slides to the first blind hole 17, the steel ball in the ball head end thereof extends out under the action of the spring and embeds into the first blind hole 17 to achieve positioning, so that the first guide plate 5 stops moving, so that the chassis roll degree no longer changes.

[0093] In the present application, when the chassis of the transplanter is adjusted to a suitable pitch, the pitch adjustment handle 6 is pushed to drive the second guide plate 7 to move horizontally, so that the second plunger ball head set screw 16 and the second guide plate 7 slide relative to each other. When the second plunger ball head set screw 16 slides to the second blind hole 18, the steel ball in the ball head end thereof extends out under the action of the spring and embeds into the second blind hole 18 to achieve positioning, so that the second guide plate 7 stops moving, so that the pitch of the chassis no longer changes.

[0094] The first half waist hole 20 of the present application can be used as a support point for the cable on the first guide plate 5 to prevent the cable from shaking excessively when it moves, and has a certain regularizing effect on the moving trajectory of the cable; the second half waist hole 21 can be used as a support point for the cable on the second guide plate 7 to prevent the cable from shaking excessively when it moves, and has a certain regularizing effect on the moving trajectory of the cable;

[0095] In this application, by setting the first nut 25 and the second nut 26, the roll adjustment handle 4 and the pitch adjustment handle 6 are restricted to both sides of the hollow controller base 1, thereby preventing the roll adjustment handle 4 and the pitch adjustment handle 6 from falling off during roll or pitch adjustment and improving the stability of adjustment;

[0096] In this application, by setting the third nut 31 and the fourth nut 32, the first plunger ball head set screw 15 is fixed in the second through hole 35, improving the stability of the first plunger ball head set screw 15 during relative sliding;

[0097] In this application, by setting the fifth nut 33 and the sixth nut 34, the second plunger ball head set screw 16 is fixed in the third through hole 36, improving the stability of the second plunger ball head set screw 16 during relative sliding.

[0098] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and not to limit them. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of this application; the dimensions of the drawings have nothing to do with the specific physical objects, and the physical dimensions can be changed arbitrarily.
