Description

Technical Field

[0001] This application relates to the field of agricultural machinery and equipment technology, and in particular to a controller for the pitch and roll adjustment valves of a transplanter chassis. Background Technology

[0002] The terrain in hilly and mountainous areas is relatively complex. When the slope of the work site changes, the chassis of the transplanter will pitch or roll. The tilted chassis will no longer remain horizontal, which will cause the transplanting tool to lose its verticality.

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

[0004] Transplanting is a crucial step in the planting of many agricultural and cash crops. In the mechanized transplanting process in hilly and mountainous areas, in order to ensure that the seedlings of the agricultural and cash crops are accurately transplanted into the prepared land, it is necessary to ensure the verticality of the transplanted seedlings. Therefore, the transplanting tools should be kept as vertical as possible, and the chassis of the transplanter should be kept as level as possible. Summary of the Invention

Example

[0045] See Figure 1 A transplanter chassis pitch and roll adjustment valve controller includes a hollow controller base 1 and an adjustment valve. A first bolt 2 passes through the hollow controller base 1, and a mounting bracket 3 is provided on the lower side of one end of the hollow controller base 1. The transplanter chassis pitch and roll adjustment valve controller further includes:

[0046] The roll adjustment handle 4 is located on one side of the hollow controller base 1 and is rotatably connected to the first bolt 2. The lower inner side of the roll adjustment handle 4 is connected to the first guide plate 5. The two ends of the first guide plate 5 pass through one side of the mounting frame 3 and are slidably connected to the mounting frame 3.

[0047] The pitch adjustment handle 6 is located on the other side of the hollow controller base 1 and is rotatably connected to the first bolt 2. The lower inner side of the pitch adjustment handle 6 is connected to the second guide plate 7. The two ends of the second guide plate 7 pass through the other side of the mounting bracket 3 and are slidably connected to the mounting bracket 3.

[0048] The mounting bracket 3 includes a first limiting plate 8 and a second limiting plate 9 disposed below the hollow controller base 1;

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

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

[0051] Pull wires are respectively provided on the first guide plate 5 and the second guide plate 7. The controller of the transplanter chassis pitch and roll adjustment valve is connected to the adjustment valve through the pull wires. 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 adjustment valve through the pull wires to make the transplanter chassis pitch and roll.

[0052] Specifically, the roll adjustment handle 4 and the pitch adjustment handle 6 are provided with holes in the middle that allow the first bolt 2 to pass through. The threaded section of the first bolt 2 passes through the pitch adjustment handle 6, the hollow controller base 1 and the roll adjustment handle 4 in sequence, fixing the roll adjustment handle 4 and the pitch adjustment handle 6 to both sides of the hollow controller base 1 respectively. The roll adjustment handle 4 and the pitch adjustment handle 6 are rotatably connected to the first bolt 2. The upper ends of the roll adjustment handle 4 and the pitch adjustment handle 6 are higher than the upper end of the hollow controller base 1, so that the operator can hold them.

[0053] The lower inner side of the roll adjustment handle 4 is detachably connected to the outer end face of the first guide plate 5. Both ends of the first guide plate 5 are inserted through the mounting frame 3 on the side near 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 near the middle of the hollow controller base 1 is connected to one end of the pull wire, and the other end of the pull wire is connected to the regulating valve.

[0054] The lower inner side of the pitch adjustment handle 6 is detachably connected to the outer end face of the second guide plate 7. Both ends of the second guide plate 7 are inserted through the mounting frame 3 on the side near 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 near the middle of the hollow controller base 1 is connected to one end of the pull wire, and the other end of the pull wire is connected to the regulating valve.

[0055] The two ends of the first guide plate 5 are respectively inserted into the first rectangular hole 10 and the third rectangular hole 12, and slide in 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 are respectively inserted into the second rectangular hole 11 and the fourth rectangular hole 13, and slide in contact with the hole walls of the second rectangular hole 11 and the fourth rectangular hole 13.

[0056] By setting the first rectangular hole 10 and the third rectangular hole 12 to restrict the movement of the first guide plate 5 in the vertical direction, the first guide plate 5 can only move in the horizontal direction, thereby converting the rotation of the roll adjustment handle 4 into the horizontal movement of the first guide plate 5, so as to drive the pull line action.

[0057] By setting the second rectangular hole 11 and the fourth rectangular hole 13 to restrict the movement of the second guide plate 7 in the vertical direction, the second guide plate 7 can only move in the horizontal direction, thereby converting the rotation of the pitch adjustment handle 6 into the horizontal movement of the second guide plate 7, so as to drive the pull line action.

[0058] When the lateral slope of the plot changes, the chassis of the transplanter will roll. At this time, turn 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 pull line to move, which changes the pull line stroke. The pull line triggers the adjustment valve to perform a control action. The adjustment valve controls the hydraulic transmission device to operate. The hydraulic transmission device drives the chassis to rise and fall to adjust the roll degree of the chassis, so that the chassis is level, 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 pull line to move, which changes the pull line stroke. The pull line triggers the regulating valve to perform a control action. The regulating valve controls the hydraulic transmission device to operate. The hydraulic transmission device drives the chassis to rise and fall to adjust the pitch of the chassis, so that the chassis is level, thereby realizing the pitch adjustment of the transplanter chassis.

[0060] In this embodiment, the pitch and roll of the transplanter chassis are adjusted by setting the roll adjustment handle 4 and the pitch adjustment handle 6. During operation, the roll adjustment handle 4 and the pitch adjustment handle 6 can be rotated in time according to the changes in the longitudinal and transverse slopes of the work plot relative to the horizontal plane to control the pitch and roll of the transplanter chassis, so that the transplanter remains horizontal and ensures the verticality of the transplanted seedlings, thereby improving the growth efficiency of agricultural crops in hilly and mountainous areas.

[0061] It should be noted that the regulating valve, the transplanter chassis, and the hydraulic transmission device are all existing technologies, and will not be discussed in detail in this application. Example

[0062] See Figure 2 and Figure 3 Based on Embodiment 1, and optionally, the mounting bracket 3 further includes a connecting plate 14 fixed between the first limiting plate 8 and the second limiting plate 9;

[0063] A first plunger ball head set screw 15 is provided at one end of the connecting plate 14 near the first limiting plate 8, and one end of the first plunger ball head set screw 15 slides in contact with the first guide plate 5.

[0064] A second plunger ball head set screw 16 is provided at one end of the connecting plate 14 near the second limiting plate 9, and one end of the second plunger ball head set screw 16 is in sliding contact with the second guide plate 7.

[0065] Specifically, the two ends of the connecting plate 14 are fixedly connected to the first limiting plate 8 and the second limiting plate 9 respectively, and the upper end of the connecting plate 14 is fixedly connected to the lower end of the hollow controller base 1; a second through hole 35 is provided at the end of the connecting plate 14 near the first limiting plate 8, allowing the first plunger ball head set screw 15 to pass through. The first plunger ball head set screw 15 is fixed in the second through hole 35, and the ball head end of the first plunger ball head set screw 15 abuts against the side wall of the first guide plate 5 near the connecting plate 14 and slides in contact with it; a third through hole 36 is provided at the end of the connecting plate 14 near the second limiting plate 9, allowing the second plunger ball head set screw 16 to pass through. The second plunger ball head set screw 16 is fixed in the third through hole 36, and the ball head end of the second plunger ball head set screw 16 abuts against the side wall of the second guide plate 7 near the connecting plate 14 and slides in contact with it.

[0066] This configuration allows the first plunger ball head set screw 15 to slide relative to the first guide plate 5 when the first guide plate 5 moves horizontally, so that the first plunger ball head set screw 15 can move to a specific position on the first guide plate 5 for positioning; this configuration also allows the second plunger ball head set screw 16 to slide relative to the second guide plate 7 when the second guide plate 7 moves horizontally, so that the second plunger ball head set screw 16 can move to a specific position on the second guide plate 7 for positioning.

[0067] See Figure 5 Furthermore, and optionally, a first blind hole 17 matching the first plunger ball head set screw 15 is provided on the side wall of the first guide plate 5 near the connecting plate 14.

[0068] A second blind hole 18 is provided on the side wall of the second guide plate 7 near the connecting plate 14, which matches the second plunger ball head set screw 16.

[0069] Specifically, when the transplanter chassis is adjusted to a suitable roll angle, 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 slides relative to the first guide plate 5. When the first plunger ball head set screw 15 slides to the first blind hole 17, the steel ball in its ball head end extends out under the action of the spring and is embedded in the first blind hole 17 to achieve positioning, so that the first guide plate 5 stops moving, so that the roll angle of the chassis no longer changes.

[0070] When the transplanter chassis is adjusted to the appropriate 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 slides relative to the second guide plate 7. When the second plunger ball head set screw 16 slides to the second blind hole 18, the steel ball in its ball head end extends out under the action of the spring and is embedded in the second blind hole 18 to achieve positioning, so that the second guide plate 7 stops moving, thereby so that the chassis pitch no longer changes. Example

[0071] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiments, and optionally, the bottom of the hollow controller base 1 away from the mounting bracket 3 is provided with a wire frame 19, and the wire frame 19 is symmetrically provided with a first half-waist hole 20 and a second half-waist hole 21 that allow the two pull wires to pass through.

[0072] Specifically, the upper end of the lead frame 19 is fixedly connected to the lower end of the hollow controller base 1. The lead frame 19 is symmetrically provided with a first semi-waist hole 20 and a second semi-waist hole 21 that allow the two pull wires to pass through, such that the side view of the lead frame 19 presents a Chinese character 'tu' shape. The first semi-waist hole 20 can serve as a support point for the pull wire on the first guide plate 5, avoiding excessive shaking when the pull wire moves and having a certain regularizing effect on the moving trajectory of the pull wire; the second semi-waist hole 21 can serve as a support point for the pull wire on the second guide plate 7, avoiding excessive shaking when the pull wire moves and having a certain regularizing effect on the moving trajectory of the pull wire.

[0073] See Figure 5 , further and optionally, a first wire hole 22 is provided at one end of the first guide plate 5 close to the lead frame 19, and a second wire hole 23 is provided at one end of the second guide plate 7 close to the lead frame 19;

[0074] Among them, the pull wire includes a roll pull wire and a pitch pull wire. The first wire hole 22 is used to fix one end of the roll pull wire, and the second wire hole 23 is used to fix one end of the pitch pull wire.

[0075] Specifically, one end of the roll pull wire is wound around the first guide plate 5 through the first wire hole 22, and the other end of the roll pull wire is connected to the regulating valve. With such a setting, the first guide plate 5, the roll pull wire, and the regulating valve form a transmission structure;

[0076] One end of the pitch pull wire is wound around the second guide plate 7 through the second wire hole 23, and the other end is connected to the regulating valve. With such a setting, the second guide plate 7, the pitch pull wire, and the regulating valve form a transmission structure.

[0077] Further and optionally, a first through hole 24 allowing the first bolt 2 to pass through is provided on the hollow controller base 1. One end of the first bolt 2 close to the roll adjusting handle 4 is threadedly connected with a first nut 25 and a second nut 26;

[0078] Among them, through the cooperation of the first nut 25, the second nut 26, and the first bolt 2, the roll adjusting handle 4 is restricted to one side of the hollow controller base 1, and the pitch adjusting handle 6 is restricted to the other side of the hollow controller base 1.

[0079] Specifically, the first through hole 24 is located above the connecting plate 14 and is used for installing the first bolt 2;

[0080] By providing the first nut 25 and the second nut 26, the roll adjusting handle 4 and the pitch adjusting handle 6 are restricted on both sides of the hollow controller base 1, thereby preventing the roll adjusting handle 4 and the pitch adjusting handle 6 from falling off during roll or pitch adjustment and improving the stability of adjustment.

[0081] Further and optionally, the lower part of the roll adjustment handle 4 is provided with a first waist-shaped hole, the first guide plate 5 is provided with a first screw hole 27, and a second bolt 28 is provided in the first waist-shaped hole and the first screw hole 27;

[0082] The lower part of the pitch adjustment handle 6 has a second oblong hole, and the second guide plate 7 has a second screw hole 29. The second oblong hole and the second screw hole 29 are provided with a third bolt 30.

[0083] Specifically, the threaded section of the second bolt 28 rotates from the outside to the inside and is screwed into the first waist-shaped hole and the first screw hole 27, so that the lower part of the roll adjustment handle 4 is fixed on the outer wall of the first guide plate 5 away from the mounting bracket 3, thereby forming a transmission structure between the roll adjustment handle 4 and the first guide plate 5.

[0084] The threaded section of the third bolt 30 is rotated from the outside to the inside and screwed into the second oblong hole and the second screw hole 29, so that the lower part of the pitch adjustment handle 6 is fixed on the outer wall of the second guide plate 7 away from the mounting bracket 3, thereby forming a transmission structure between the pitch adjustment handle 6 and the first guide plate 5.

[0085] Further and optionally, the first plunger ball head set screw 15 is threaded with a third nut 31 and a fourth nut 32 at both ends;

[0086] The second plunger ball head set screw 16 has a fifth nut 33 and a sixth nut 34 threadedly connected to both ends.

[0087] Specifically, the third nut 31 is located at the end of the first plunger ball head set screw 15 near the second guide plate 7, and the fourth nut 32 is located at the end of the first plunger ball head set screw 15 near the first guide plate 5. 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, thereby improving the stability of the first plunger ball head set screw 15 when it slides relative to the second guide plate 5.

[0088] The fifth nut 33 is located at the end of the second plunger ball head set screw 16 near the second guide plate 7, and the sixth nut 34 is located at the end of the second plunger ball head set screw 16 near the first guide plate 5. 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, thereby improving the stability of the second plunger ball head set screw 16 when it slides relative to the others.

[0089] In summary, this application adjusts the pitch and roll of the transplanter chassis by setting the roll adjustment handle 4 and the pitch adjustment handle 6. During operation, the roll adjustment handle 4 and the pitch adjustment handle 6 can be rotated in a timely manner according to the changes in the longitudinal and transverse slopes of the work plot relative to the horizontal plane, so as to control the pitch and roll of the transplanter chassis, keep the transplanter level, ensure the verticality of the transplanted seedlings, and achieve the purpose of improving the growth efficiency of agricultural and economic crops in hilly and mountainous areas.

[0090] This application restricts the movement of the first guide plate 5 in the vertical direction by setting the first rectangular hole 10 and the third rectangular hole 12, so that the first guide plate 5 can only move in the horizontal direction, thereby converting the rotation of the roll adjustment handle 4 into the horizontal movement of the first guide plate 5, so as to drive the pull line action.

[0091] This application restricts the movement of the second guide plate 7 in the vertical direction by setting the second rectangular hole 11 and the fourth rectangular hole 13, so that the second guide plate 7 can only move in the horizontal direction, thereby converting the rotation of the pitch adjustment handle 6 into the horizontal movement of the second guide plate 7, so as to drive the pull line action.

[0092] When the transplanter chassis is adjusted to a suitable roll angle, 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 slides relative to the first guide plate 5. When the first plunger ball head set screw 15 slides to the first blind hole 17, the steel ball in its ball head end extends out under the action of the spring and is embedded in the first blind hole 17 to achieve positioning, so that the first guide plate 5 stops moving, so that the roll angle of the chassis no longer changes.

[0093] When the transplanter chassis 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 slides relative to the second guide plate 7. When the second plunger ball head set screw 16 slides to the second blind hole 18, the steel ball in its ball head end extends out under the action of the spring and is embedded in the second blind hole 18 to achieve positioning, so that the second guide plate 7 stops moving, thereby so that the chassis pitch no longer changes.

[0094] The first half-waist hole 20 of this application can serve as a support point for the pull wire on the first guide plate 5, preventing excessive shaking when the pull wire moves and having a certain regularizing effect on the movement trajectory of the pull wire; the second half-waist hole 21 can serve as a support point for the pull wire on the second guide plate 7, preventing excessive shaking when the pull wire moves and having a certain regularizing effect on the movement trajectory of the pull wire.

[0095] This application sets a first nut 25 and a second nut 26, which restricts the roll adjustment handle 4 and the pitch adjustment handle 6 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] This application improves the stability of the first plunger ball head set screw 15 when it slides relative to the second through hole by setting a third nut 31 and a fourth nut 32 to fix the first plunger ball head set screw 15 in the second through hole 35.

[0097] This application improves the stability of the second plunger ball head set screw 16 when it slides relative to the third through hole 36 by setting a fifth nut 33 and a sixth nut 34.

[0098] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. 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 to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
