Riding ditcher

Abstract

The application provides a riding ditcher, which is hung by a mounting frame and a high-speed transplanter suspension. The mounting frame is fixedly connected with a cross beam. A pair of mounting plates are fixedly connected with the cross beam through bolts. A connecting shaft is inserted into a sleeve of the mounting plate. A shaft sleeve connecting frame is sleeved on the lower part of the connecting shaft. The bottom of the connecting shaft is limited by the connecting frame through a pin shaft. The upper part of the connecting frame is limited by a limiting ring. Symmetrical ears are arranged on the front and back sides of the limiting ring. Fan-shaped cams are arranged on the both sides of the upper end of the shaft sleeve of the connecting frame. When the connecting frame rotates, the fan-shaped cams are limited by the pin shaft in the ears. The left and right swinging of the connecting frame is limited. Thus, the riding ditcher can move along with the high-speed transplanter during operation.

Description

Technical Field

[0001] This invention relates to an agricultural machinery part, and more particularly to a ride-on trencher. Background Technology

[0002] Ditching can help rice achieve a high yield. Most ditching machines on the market are hand-held, requiring manual riding during operation, which is quite strenuous. The ditching device is rigidly connected to the frame, and it is easy to damage the rice seedlings in the field when turning. Summary of the Invention

[0003] Based on this, it is necessary to address the problems of time-consuming and laborious ditching in paddy fields and the easy damage to seedlings when turning during operation. This utility model provides a ride-on ditching machine, including a mounting frame that is connected to the suspension of a high-speed rice transplanter, a crossbeam fixedly connected to the mounting frame, a pair of mounting plates with sleeves fixedly connected to both sides of the crossbeam by bolts, a connecting shaft inserted into the sleeve of the mounting plate, a connecting frame with a bushing fitted on the lower part of the connecting shaft, the bottom of the connecting shaft is limited by a pin to the bottom of the connecting frame, and the connecting plate on the other side of the connecting frame is movably connected to the ditcher through upper and lower shaft holes.

[0004] Preferably, the connecting bracket fitted on the connecting shaft has a limit ring fitted at its upper end, and the limit ring and the connecting shaft are limited at the upper end by locking bolts.

[0005] Preferably, the limiting ring has symmetrical ears on both the front and rear sides, with one ear having an angle of 45 degrees to the center and the other ear having an angle of 90 degrees to the center. The ears have round holes for installing pins. The upper end of the bushing of the connecting frame has fan-shaped cams on both sides. When the connecting frame rotates, the pins limit the fan-shaped cams, thereby limiting the left and right swing of the connecting frame.

[0006] Preferably, the crossbeam is provided with multiple sets of mounting holes, and the mounting plate can be adjusted in position on the crossbeam to adjust the row spacing of the trench.

[0007] Compared with the prior art, the present invention has the following advantages:

[0008] 1) This ditching machine can be connected to high-speed rice transplanters on the market. By replacing the transplanting part at the rear of the high-speed rice transplanter with this ditching machine, field ditching can be achieved without manual intervention in the field, resulting in high work efficiency and low labor intensity.

[0009] 2) The trencher in this trencher is flexibly connected to the support frame. When turning or encountering seedlings, it can deviate at a certain angle to avoid damaging the seedlings and make turning more flexible. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0015] like Figure 1-2 As shown, in this embodiment, the riding-type furrow opener 10 includes a mounting frame 11 that can be attached to the high-speed rice transplanter suspension 20. A crossbar 12 is fixed to the mounting frame 11, and a pair of mounting plates 13 are connected to both sides of the crossbar 12. The crossbar 12 has multiple sets of mounting holes. The distance between the furrow openers 17 can be adjusted by adjusting the mounting position of the mounting plates 13 on the crossbar 12, typically 1 meter or 1.2 meters (suitable for rice transplanting row spacing of 25cm or 300cm). One side of the mounting plate 13 is bolted to the crossbar 12, and the other side is fixed with a sleeve 131. A connecting shaft 14 is fitted inside the sleeve 131. The connecting shaft 14 is limited above and below the sleeve 131 by pins. The lower end of the connecting shaft 14 is fitted inside the connecting frame 15. One side of the connecting frame 15 is a bushing 151, and the other side is a connecting plate 152. The upper end of the connecting frame 15 is limited by a limiting ring 16 and a locking bolt, and the lower end is limited by a pin. The connecting plate 152 on one side of the mounting frame 15 is movably connected to the furrow opener 17 by two sets of pins. When the furrow opener 17 is working in the field, it can be adjusted up and down to make fine adjustments according to the depth of the rice field. The bushing 151 of the mounting frame 15 has fan-shaped cams on both sides of its upper end. The limiting ring 16 has a pair of ears at the front and back. Pins or bolts can be fitted inside the ears. The front pair of ears has an angle of 45 degrees with the center line of the limiting ring, and the rear pair of ears has an angle of 90 degrees with the center line of the limiting ring. The connecting plate 152 drives the trencher 17 to rotate within the connecting shaft 14. The swing amplitude is limited by the sector-shaped cam at the upper end of the mounting bracket 15 and the pin passing through one of the ears on the limiting ring 16. By reversing the installation of the limiting ring 16, two swing amplitudes, 45 degrees and 90 degrees, can be achieved. The trencher 17 is wedge-shaped and has a blade at the front end.

[0016] During field operations, the installation position of the mounting plate 152 on the crossbar 12 is adjusted according to the row spacing of the rice seedlings planted earlier, thereby adjusting the distance between the two sets of furrow openers 17. Depending on the field conditions, the appropriate limit ring 16 is installed before and after installation, and the entire furrow opener is connected to the rear suspension of the high-speed rice transplanter for riding-style field furrow opening. When encountering seedlings during furrow opening, the furrow opener avoids the seedlings by small swings. When turning, it can flexibly turn and open furrows by small swings. During operation, the furrow opener can be finely adjusted up and down around the connecting frame according to the depth of the field.

[0017] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. In addition to the above embodiments, this utility model may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
