Technical Field

[0001] The present invention relates to the technical field of gardening machinery and tools, in particular to a truss-mounted row-changing device for gardening. Background Art

[0002] Existing gardening machines usually operate in rows when performing gardening pruning and other operations. After completing a row of operations, due to the large size of the gardening machines and the small row spacing, the space is limited, and the large size of the gardening machines makes it difficult to turn around and operate in the opposite direction. The only option is to return to a relatively open position at the end of the row, adjust the machine direction, and then operate the next row. This type of machine is not suitable for gardening operations with small row spacing such as tea gardens. The use of the machine is greatly restricted, and the operation efficiency is low. It is difficult to achieve on-site U-turns and cross-row operations. In this regard, a truss-mounted row change device is proposed to solve the above problems. Summary of the Invention

The oil cylinders are respectively connected to an external remote control end through wireless signals. The right push-out oil cylinder 11 or the left push-out oil cylinder 12 can be remotely controlled through the external remote control end. When it is necessary to change the row of the gardening implement, the push rod of the right push-out oil cylinder 11 is pushed out through the control of the remote control end, and the push rod of the left push-out oil cylinder 12 is retracted at the same time.

[0042] As shown by contents of the description, Figure 4 As shown by contents of the description, the top surface of the clamping cone plate 6 is fixedly provided with two clamping rods 601, the upper section of the clamping rod 601 has a larger diameter than the lower section, the inside of the clamping cone plate 6 is provided with a rectangular hole, and the inside of the rectangular hole movably clamps the clamping hook 4011, when the hydraulic cylinder 4 is raised, the clamping hook 4011 is kept at the lowest position by the pushing of the push rod, the clamping cone plate 6 is pushed downward until the clamping hook 4011 is attached to the lowest point of the rectangular hole in the inside of the clamping cone plate 6, the clamping cone is inserted into the ground, and when the hydraulic cylinder 4 continues to push, the push rod will enlarge the spacing between the clamping cone plate 6 and the fixed clamping plate 402, the clamping rod 601 slides in the round hole in the inside of the guide plate 5 until the clamping rod 601 is located at the lowest part of the round hole in the guide plate 5, the push rod continues to move, the limiting block 4021 is clamped to the highest point of the through hole in the guide plate 5, the touch switch is touched to automatically stop the hydraulic cylinder 4, the rising is completed, when the hydraulic cylinder 4 is retracted, the spacing between the push rod and the fixed clamping plate 402 is reduced, the clamping hook 4011 pulls the clamping cone plate 6 upward until the clamping hook 4011 is attached to the top end of the rectangular hole in the inside of the clamping cone plate 6, the push rod continues to retract to relatively slide the clamping rod 601 in the round hole in the inside of the guide plate 5, after the clamping rod 601 is clamped to the top end of the round hole in the inside of the guide plate 5, the push rod continues to retract to relatively slide the limiting block 4021 in the guide plate 5, moves to the lowest point of the through hole in the guide plate 5, touches the touch switch to indicate that the hydraulic cylinder 4 is retracted, and the hydraulic cylinder 4 is automatically stopped by the external control terminal to complete the descending.

[0043] As shown by contents of the description, Figure 3 As shown by contents of the description, the truss 3 is composed of four parallel rod members welded with inclined support rods, the two ends of the truss 3 are fixedly welded with the parallel rod members through rectangular plates, the truss 3 can ensure that the heights of the hydraulic cylinders 4 are the same and the mutual parallel between the left and right, and can reduce the self weight of the truss 3 and the load of the horticultural implement during the horticultural operation.

[0044] In the second embodiment, based on the first embodiment, the motor and the connecting plate 201 are eliminated, and the bottom connecting plate of the connecting frame 2 is directly connected to the gardening machine. The gardening machine is self-propelled by the crawler to perform gardening pruning operations. After the row operation is completed, the steering structure on the gardening machine is activated to turn around on the spot and prune the next row. After completion, the gardening machine is lifted by the hydraulic cylinder 4, and the position of the gardening machine is moved by the cylinder assembly 1. The gardening machine is then lowered to the ground by the hydraulic cylinder 4 to complete the automatic row change of the gardening machine. The gardening machine is then activated again to perform the gardening pruning operation. This process is repeated until the operation is completed.

[0045] In the third embodiment, based on the first embodiment, the truss 3 can be changed into a telescopic structure, so that the distance between the front and rear hydraulic cylinders 4 can be adjusted to ensure stability and reduce the load of the gardening machinery.

[0046] The working principle of this embodiment is as follows: the gardening tool is fastened to the bottom surface of the connecting rotating plate 201 via a bolt assembly, and the connecting frame 2 is fixedly connected to the bottom of the connecting member 7. When the gardening tool is operated to perform gardening operations, the connecting frame 2 drives the cylinder assembly 1, the truss 3, and the hydraulic cylinder 4 to move synchronously, and the rollers are used to reduce the load on the gardening tool. When it is necessary to turn around in place, the push rod of the hydraulic cylinder 4 is pushed out to raise the hydraulic cylinder 4, and then the motor is started to drive the gardening tool to turn to complete the turn. Then, the push rod of the hydraulic cylinder 4 is retracted and lowered to the ground to complete the turn.

[0047] When the push rod of the hydraulic cylinder 4 is extended, the base plate 401 and the hook 4011 are relatively displaced from the fixing tube of the hydraulic cylinder 4. The push rod of the hydraulic cylinder 4 pushes the hydraulic cylinder 4 to rise until the hook 601 is located at the lowest point of the circular hole in the guide plate 5. The push rod continues to move, pulling the limit block 4021 to engage with the highest point of the through hole in the guide plate 5, and pressing the touch switch to automatically stop the hydraulic cylinder 4, completing the rise.

[0048] By operating the remote control to push out the push rod of the right push cylinder 11 and retract the push rod of the left push cylinder 12, the gardening tool can be driven from left to right to complete the cross-row movement.

[0049] When the hydraulic cylinder 4 is retracted, the push rod drives the gap between the base plate 401 and the fixed clamping plate 402 to decrease, pushing the limit block 4021 to slide relatively inside the guide plate 5 until the limit block 4021 is at the lowest point of the through hole in the guide plate 5. The touch-pressure switch is pressed, indicating that the hydraulic cylinder 4 has completed retraction. The hydraulic cylinder 4 is automatically stopped by the external control terminal, and the descent is completed. Then, the gardening operation can be continued until the operation is completed.
