[0023] like Figure 1 As shown, a pond digging machine for deepening the pond digging depth includes a pond digging machine frame 1, a driving device 2, a reduction box 3, and an alternating pond digging and deep digging mechanism 4. The driving device 2 is installed at a position close to the front end of the pond digging machine frame 1, and the pond digging machine frame 1 can be driven by the driving device 2 to rotate and move forward through four running wheels arranged thereon. An L-shaped mounting plate is arranged on the pond digging machine frame 1, one side plate of the L-shaped mounting plate is vertically distributed and fixed to the pond digging machine frame 1 by bolts, and the reduction box 3 is installed on the other side plate of the L-shaped mounting plate along the horizontal distribution by bolts.
[0024] like Figure 3As shown, a driven wheel is installed on the input end of the reduction box 3, a driving wheel is installed on the output shaft of the driving device 2, and a transmission belt 301 is sleeved between the driving wheel and the driven wheel. The driving device 2 drives the input end of the reduction box 3 to rotate through the transmission belt 301, so that the output end of the reduction box 3 can achieve synchronous rotation.
[0025] like Figure 2 and Figure 3 As shown, the alternating pond digging and deep digging mechanism 4 includes a crank 1 403, a crank 2 404, a short swing square tube 402, a long swing square tube 405, a first shovel 5, and a second shovel 6. A short connecting rod is arranged on the L-shaped mounting plate, one end of the short connecting rod is fixed to the L-shaped mounting plate, and the short swing square tube 402 is rotatably arranged at an end of the short connecting rod away from the reduction box 3, so that the short swing square tube 402 can rotate with the short connecting rod as a fulcrum. A first sliding hole 402a is penetrated and opened on the left and right side walls of the short swing square tube 402, and a rolling connector 406 that can roll along its length direction is arranged inside the short swing square tube 402.
[0026] The rolling connection member 406 includes a connecting long shaft 406b and a connecting deep groove ball bearing 406a sleeved on the middle of the connecting long shaft 406b, and the connecting deep groove ball bearing 406a can roll along the length direction of the short pendulum square tube 402. The connecting long shaft 406b crosses the short pendulum square tube 402, and both ends of the connecting long shaft 406b pass through the first sliding hole 402a on the corresponding side and are located outside the short pendulum square tube 402. A first deep groove ball bearing 403a for rotationally connecting with the connecting long shaft 406b is provided at one end of the crank 1 403. The first deep groove ball bearing 403a is rotationally arranged at the end of the crank 1 403, and the end of the connecting long shaft 406b extending out of the first sliding hole 402a on the corresponding side is fixedly connected to the outer ring of the first deep groove ball bearing 403a.
[0027] The other end of the crank 403 away from the first deep groove ball bearing 403a is fixed on the output end of the reduction gearbox 3. The crank 403 can swing along an arc as the output end of the reduction gearbox 3 rotates. The swinging crank 403 drives the connected deep groove ball bearing 406a to roll back and forth along the length direction of the short pendulum square tube 402 through the connecting long shaft 406b connected to the first deep groove ball bearing 403a. As the connected deep groove ball bearing 406a rolls back and forth in the short pendulum square tube 402, the short pendulum square tube 402 can swing up and down with the short connecting rod as the fulcrum.

[0029] A connecting rod is welded and fixed on the first shovel 5, one end of which is fixedly connected to the first shovel 5, and the other end passes through the first length adjustment sleeve 401a. Two fastening bolts are arranged on the first length adjustment sleeve 401a along its length direction. The first shovel 5 is fixed to the connecting rod by rotating and tightening the two fastening bolts, and the corresponding connecting rod can be slid in the first length adjustment sleeve 401a by rotating and loosening the two fastening bolts, so as to adjust the extension length of the first shovel 5 according to the height of the field ridge. In the process of the pond digging machine frame 1 moving along the field ridge, the first shovel 5 can swing and dig a groove as the short swing square tube 402 swings up and down.
[0030] The top plate 401d is arranged between the short pendulum square tube 402 and the reduction box 3, one end of the top plate 401d is welded and fixed on the angle adjustment sleeve 401b, and the other end is tightly against the first deep groove ball bearing 403a. When the first deep groove ball bearing 403a rotates and moves toward the direction of the first shovel 5, it will push the top plate 401d to move, and the moving top plate 401d will push the angle adjustment sleeve 401b to rotate, and the first shovel 5 fixed on the angle adjustment sleeve 401b will rotate accordingly. The depth of the groove dug by the first shovel 5 after the angle is fine-tuned is a little deeper than the depth when the angle is not fine-tuned, so that the depth of the groove dug by the first shovel 5 when digging the pond is close to the depth required by agronomy. A tension spring 401c is arranged between the short pendulum square tube 402 and the angle adjustment sleeve 401b, one end of the tension spring 401c is fixed on the angle adjustment sleeve 401b, and the other end is fixed on the short pendulum square tube 402.
[0031] One end of the second crank 404 is rotatably mounted on the end of the connecting long shaft 406b away from the first crank 403, and the other end of the second crank 404 is mounted with a second deep groove ball bearing 404a. In addition, a long connecting rod is arranged on the L-shaped mounting plate, one end of the long connecting rod is fixed on the L-shaped mounting plate, one end of the long pendulum square tube 405 is rotatably mounted on the other end of the long connecting rod, and second sliding holes 405a are penetrated and opened on both side walls of the long pendulum square tube 405. The second deep groove ball bearing 404a passes through the second sliding hole 405a and is located in the long pendulum square tube 405, and can roll along the length direction of the long pendulum square tube 405.
[0032] The connected deep groove ball bearing 406a that rolls back and forth in the short pendulum square tube 402 can drive the second crank 404 to swing along an arc, and the second deep groove ball bearing 404a can roll back and forth in the long pendulum square tube 405 with the reciprocating swing of the second crank 404, and drive the long pendulum square tube 405 to swing up and down with the long connecting rod as a fulcrum, thereby driving the second shovel 6 that is arranged on the end of the long pendulum square tube 405 away from the long connecting rod through the second angle adjustment component 407 to swing up and down accordingly, and dig a pond and trench again on the basis of the first trench, thereby deepening the depth of the trench, so that the trench depth can meet the agronomic planting requirements in some areas.
[0033] like Figure 3 and Figure 4 As shown, the second angle adjustment assembly 407 includes a long rod 407a, a short rod 407d, a second length adjustment sleeve 407c and two half ratchets 407b. One end of the long rod 407a is vertically fixed to the end of the long pendulum square tube 405 away from the long connecting rod, and the other end of the long rod 407a is installed with a half ratchet 407b. Another half ratchet 407b is installed at the end of the short rod 407d, and the two half ratchets 407b are meshed and can be fixed by bolts. The second length adjustment sleeve 407c is welded and fixed to the short rod 407d. A connecting rod is fixed to the second shovel 6, and the connecting rod is inserted into the second length adjustment sleeve 407c. The second length adjustment sleeve 407c is provided with two tightening bolts spaced apart along its length direction. The ends of the two tightening bolts are tightly pressed against the connecting rod as they rotate, thereby fixing the second shovel 6 to the rear of the first shovel 5. In addition, after loosening the bolt between the two half ratchets 407b, the half ratchet 407b on the short rod 407d can be rotated, and the rotated half ratchet 407b can be engaged with another half ratchet 407b and then fixed by bolts, so that the angle of the second shovel 6 can be adjusted according to actual needs.
[0034] The specific implementation of the utility model is as follows: First, the running wheels on the pond digging machine frame 1 are moved to the field ridges on both sides of the field ridge, and at this time, the first shovel 5 and the second shovel 6 are both lifted away from the field ridge. The driving device 2 is started, and the pond digging machine frame 1 moves along the length of the field ridge. At the same time, the driving device 2 drives the crank 403 installed on the output end of the reduction box 3 to rotate along the circumference through the transmission belt 301, and drives the connected deep groove ball bearing 406a to roll toward the direction of the first shovel 5 through the first deep groove ball bearing 403a. The first deep groove ball bearing 403a rotates to push the top plate 401d to move, and the angle adjustment sleeve 401b rotates to fine-tune the rotation angle of the first shovel 5 under the push of the top plate 401d. The first shovel 5 is inserted into the field ridge as the short swing square tube 402 swings from top to bottom, and the short swing square tube 402 swings from bottom to top as the connected deep groove ball bearing 406a rolls away from the first shovel 5, and the first shovel 5 swings from bottom to top to dig a groove.
[0035] When the first shovel 5 has dug a primary groove and moved up to the initial position driven by the short swing square tube 402, the pond digging machine frame 1 continues to move forward. The connected deep groove ball bearing 406a rolling in the direction away from the first shovel 5 drives the second crank 404 to swing, and the second deep groove ball bearing 404a then rolls in the long swing square tube 405 in the direction of the second shovel 6, and the long swing square tube 405 then swings from top to bottom, and drives the second shovel 6 to insert into the primary groove from top to bottom. The long swing square tube 405 swings from bottom to top as the first deep groove ball bearing 403a rolls in the direction away from the second shovel 6, and drives the second shovel 6 to swing from bottom to top to complete the secondary groove digging in the primary groove.
