It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0044] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0045] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in the direction shown in the accompanying drawings or in terms of the vertical, perpendicular or gravitational direction for describing the relative positional relationship of each component.

[0046] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0047] The present utility model first provides a pond-digging device.

[0048] In one embodiment, referring to the attached Figure 1 and the attached Figure 2 As shown, the pond-digging device includes a swing arm 1, a shovel arm 2, a pit-opening shovel 3 and a connecting rod 4. The swing arm 1 extends in the front-rear direction and the front end can swing up and down around the rear end. The shovel arm 2 is arranged below the swing arm 1 and extends in the front-rear direction. The front end of the shovel arm 2 can swing up and down around the rear end. The pit-opening shovel 3 is fixedly connected to the front end of the shovel arm 2 and the shovel tip is arranged downward. One end of the connecting rod 4 is movably connected to the front end of the swing arm 1, and the other end extends downward and is movably connected to the root of the shovel arm 2 or the pit-opening shovel 3. The length of the connecting rod 4 is adjustable.

[0049] In the pond-digging device of this embodiment, the up-and-down swing of the front end of the swing arm 1 around the rear end can drive the pit-opening shovel 3 to make an up-and-down reciprocating motion through the connecting rod 4, thereby realizing the pond-digging function. The length of the connecting rod 4 is adjustable. With such a setting, by adjusting the length of the connecting rod 4, the amplitude range of the up-and-down reciprocation of the pit-opening shovel 3 can be adjusted, so as to realize the adjustment of the pond-digging depth of the pit-opening shovel 3. In actual application, the length of the connecting rod 4 can be adjusted according to the depth requirements of the pond for different crops or different planting areas, so that the pond-digging depth of the pond-digging device can meet the requirements. In this way, the applicability of the pond-digging device is effectively improved. For example, when the depth of the pond to be formed is relatively deep, the length of the connecting rod 4 can be extended; when the depth of the pond to be formed is relatively shallow, the length of the connecting rod 4 can be shortened.

[0050] Specifically, one end of the connecting rod 4 is hinged to the front end of the swing arm 1, and the other end extends downward and is hinged to the root of the shovel arm 2 or the pit-opening shovel 3.

[0051] In one embodiment, referring to the attached Figure 1 and the attachedFigure 2 As shown, the connecting rod 4 includes a double-headed screw 41, a first rod body 42 and a second rod body 43. The thread directions at both ends of the double-headed screw 41 are opposite. The first end of the first rod body 42 is movably connected to the front end of the swing arm 1, the second end is threadedly connected to one end of the double-headed screw 41, the first end of the second rod body 43 is threadedly connected to the other end of the double-headed screw 41, and the second end is movably connected to the root of the shovel arm 2 or the pit digging shovel 3.

[0052] Specifically, the first end of the first rod body 42 is hinged to the front end of the swing arm 1, and the second end of the second rod body 43 is hinged to the root of the shovel arm 2 or the pit digging shovel 3.

[0053] Since the thread directions at both ends of the double-headed screw 41 are opposite and are respectively threadedly connected to the second end of the first rod body 42 and the first end of the second rod body 43, with such a setting, by screwing the double-headed screw 41, the first rod body 42 and the second rod body 43 can move axially towards or away from each other, thereby realizing the adjustable length of the connecting rod 4.

[0054] Of course, in some other embodiments, the connecting rod 4 can also be in other structural forms. For example, the connecting rod 4 can include a third rod body, a fourth rod body and a quick-release pin. The first end of the third rod body is movably connected to the front end of the swing arm 1. The first end of the fourth rod body is slidably inserted into the second end of the third rod body. The second end of the fourth rod body is movably connected to the root of the shovel arm 2 or the pit digging shovel 3. The second end of the third rod body is provided with a first adjustment through hole. The first end of the fourth rod body is provided with a plurality of second adjustment through holes along the axial direction. The quick-release pin is inserted into the first adjustment through hole and one of the plurality of second adjustment through holes to fixedly connect the third rod body and the fourth rod body. With such a setting, by selectively inserting the quick-release pin into one of the plurality of second adjustment through holes, the connection position between the first end of the fourth rod body and the second end of the third rod body can be adjusted, thereby realizing the adjustable length of the connecting rod 4.

[0055] In one embodiment, referring to the attached Figure 1 and the attached Figure 2 As shown, a coaxially arranged first nut is fixedly connected to the second end of the first rod body 42. One end of the double-headed screw 41 is threadedly connected to the first nut. A coaxially arranged second nut is fixedly connected to the first end of the second rod body 43. The other end of the double-headed screw 41 is threadedly connected to the second nut.

[0056] Specifically, the first nut can be fixedly connected to the second end of the first rod body 42 by welding, and the second nut can be fixedly connected to the first end of the second rod body 43 by welding.

[0057] In one embodiment, the pit-opening shovel 3 is detachably connected to the front end of the shovel arm 2, and the connection position is adjustable along the direction from the root to the tip of the pit-opening shovel 3. With such a setting, on the one hand, according to the depth of the pond and the diameter of the pond mouth to be formed, a suitable specification of the pit-opening shovel 3 can be selected from different specifications of the pit-opening shovel 3 for replacement. On the other hand, by adjusting the connection position between the pit-opening shovel 3 and the front end of the shovel arm 2, the pond-digging depth of the pond-digging device can also be adjusted. Combined with the adjustable length of the connecting rod 4, the adjustment range of the pond-digging depth of the pond-digging device can be further expanded.

[0058] In one embodiment, referring to the attached Figure 1 and the attached Figure 2 As shown, a connecting plate 21 is fixedly provided at the front end of the shovel arm 2.

The pond-digging device further includes a first fastener, and the first fastener detachably passes through the second connection hole and one of the plurality of first connection holes to fixedly connect the pit-opening shovel 3 and the front end of the shovel arm 2. With such a setting, the detachable connection between the pit-opening shovel 3 and the front end of the shovel arm 2 is realized, and the connection position is adjustable along the direction from the root to the tip of the pit-opening shovel 3.

[0059] Specifically, the first fastener can be a fastening bolt or a quick-release pin. In addition, the connecting plate 21 can be welded or integrally formed at the front end of the shovel arm 2.

[0060] In one embodiment, referring to the attached Figure 1 and the attached Figure 2 As shown, the pond-digging device further includes a driving member, a driving arm 5, and a transmission arm 6. The driving arm 5 extends in the front-rear direction. The driving arm 5 is drivingly connected to the driving member, and the driving arm 5 can swing up and down around the rear end under the drive of the driving member. One end of the transmission arm 6 is movably connected to the driving arm 5, and the other end is movably connected to the swing arm 1. Among them, the up-and-down swing of the driving arm 5 can drive the front end of the swing arm 1 to swing up and down through the transmission arm 6.

[0061] It can be understood that the driving arm 5 swings up and down around the rear end under the drive of the driving member, which can drive the front end of the swing arm 1 to swing up and down through the transmission arm 6, and then drive the pit-opening shovel 3 to make a reciprocating up-and-down movement through the connecting rod 4 to realize the pond-digging function.

[0062] In practical applications, the rear end of the swing arm 1 and the rear end of the shovel arm 2 can be respectively hinged to the frame of the transplanter. The driving member can be a rotary driving member such as a motor and is installed on the frame of the transplanter. The rotary output shaft of the driving member is key-connected to the rear end of the driving arm 5, so as to drive the rear end of the driving arm 5 to rotate and drive the driving arm 5 to swing up and down around the rear end.

[0063] In one embodiment, one end of the transmission arm 6 is detachably connected to the driving arm 5, and the connection position is adjustable along the length direction of the driving arm 5. With such a setting, by adjusting the connection position of one end of the transmission arm 6 to the driving arm 5, the swing amplitude of the swing arm 1 can be adjusted, so as to adjust the amplitude range of the reciprocating up and down movement of the pit-opening shovel 3, thereby realizing the adjustment of the pond-digging depth of the pit-opening shovel 3. Combined with the adjustable length of the connecting rod 4, the adjustment range of the pond-digging depth of the pond-digging device can be further expanded.

[0064] In one embodiment, referring to the attached Figure 3 As shown, the driving arm 5 is provided with a limiting groove and a long slot that both extend along the length direction. The pond-digging device further includes a connecting member 7 and a fastener. The connecting member 7 includes a limiting block portion and a hinge shaft portion.

The second fastener is detachably inserted through the long slot and the second connection hole to fixedly connect the limiting block portion and the driving arm 5. One end of the transmission arm 6 is rotatably sleeved on the hinge shaft portion.

[0065] It can be understood that by detachably inserting the second fastener through the long slot and the second connection hole to fixedly connect the limiting block portion and the driving arm 5, the detachable connection of one end of the transmission arm 6 to the driving arm 5 and the adjustable connection position along the length direction of the driving arm 5 can be realized. Specifically, the second fastener can be a fastening bolt or a quick-release pin.

[0066] In one embodiment, referring to the attached Figure 3 As shown, a long rack extending along the length direction of the driving arm 5 is formed on the groove wall of the limiting groove, and a short rack meshing with the long rack is formed on the limiting block portion. With such a setting, through the meshing action of the long rack and the short rack, the limiting effect on the limiting block in the length direction of the driving arm 5 is achieved, avoiding the sliding and offset of the limiting block along the limiting groove during operation.
