[0035] like Figures 1 to 6 As shown, the utility model provides a traction-type special leveling machine for irrigated land.

[0036] Specifically, by Figure 1-Figure 6 Given, including:

[0037] Main frame 1;

[0038] A folding assembly for changing the range of land preparation;

[0039] The folding assembly includes a U-shaped frame 12 fixedly installed in the middle position of the top surface of the main frame 1, a folding frame 13 installed on one side of the main frame 1, a mounting block 16 fixedly installed above the folding frame 13, a second cylinder 15 rotatably connected inside the mounting block 16, a rotating connecting block 20 fixedly connected to the edge position of the top surface of the folding frame 13, and a retaining column 21 fixedly installed at the edge position of the top surface of the main frame 1.

[0040] In the utility model, when the device encounters a smaller piece of land during use, the user can start the two second cylinders 15. After the second cylinders 15 are started, they will drive the mounting block 16 to retract, and the mounting block 16 is fixedly mounted on the folding frame 13. The folding frame 13 is rotatably connected to the main frame body 1 through the retaining column 21. Therefore, after the second cylinder 15 drives the mounting block 16 to retract, the folding frame 13 itself will rotate, thereby moving away from the ground and reducing the lateral footprint of the device, so that the device can be used more freely in small farmlands.

[0041] Furthermore, as a specific implementation of the utility model, the utility model provides a traction-type special leveling machine for irrigated land.

[0042] Specifically, Figure 1 -

[0043] Figure 5 As shown, it also includes a moving component, which includes a rotatable first cylinder 14 connected above the U-shaped frame 12, a docking rod 11 fixedly connected to the rear end of the first cylinder 14, a hinge plate 23 fixedly installed on the rear side of the main frame body 1, a connecting frame 9 rotatably connected to the outer wall of the hinge plate 23, and rotatable moving wheels 8 installed on both sides of the rear end of the connecting frame 9.

[0044] In the utility model, the device is first connected to other agricultural machinery through the docking interface 6 opened at the front end of the tripod 5, and then the device is driven to move by the agricultural machinery. During the movement of the device, the device can be adjusted according to the road conditions. When the device is just starting, it is generally a cement ground. At this time, the entire device can be driven to move by relying on the moving wheels 8 in conjunction with the agricultural machinery. When the device enters the farmland, the user can start the first cylinder 14 to make the first cylinder 14 start to shrink. After the first cylinder 14 starts to shrink, the docking rod 11 connected to one end of the first cylinder 14 will be driven by the first cylinder 14, and the docking rod 11 is installed on the top surface of the connecting frame 9, and the connecting frame 9 is rotatably connected to the main frame body 1 The rear side of the device, therefore, after the first cylinder 14 drives the docking rod 11 to retract, the connecting frame 9 will gradually move up during the retraction process until the two moving wheels 8 are completely off the ground. At this time, the main frame 1 and the folding frame 13 can be used to level the land. When the device is used in winter, frozen soil is often encountered. If the device is forced to be used on frozen soil, it is easy to cause the device to be damaged. At this time, the user can start the first cylinder 14, and push the docking rod 11 through the first cylinder 14 to make the moving wheel 8 gradually contact with the ground, thereby reducing the resistance to forward movement. At the same time, without making the moving wheel 8 fully support the device, the device can still level the land during the movement without being damaged.

[0045] When the device completes leveling a piece of land, the first cylinder 14 can be started again, so that the first cylinder 14 pushes the docking rod 11 to the initial position. At this time, the moving wheel 8 is completely on the ground. In this way, after the agricultural machinery drives the device to the concrete ground, the device will not be easily damaged, and the ground is also protected.

[0046] Furthermore, as another specific implementation of the utility model, the utility model provides a traction-type special leveling machine for irrigated land.

[0047] Specifically, Figure 1 -

The interior of the mounting block 16 is connected to a rotatable second cylinder 15, and the other end of the second cylinder 15 is rotatably connected to the top of the U-shaped frame 12.

[0049] In the utility model, by setting a rotating connecting block 20 and a hinged connection with the retaining column 21, the folding frame 13 can be rotated by the retaining column 21 when the second cylinder 15 is contracted, so that the folding frame 13 can be smoothly folded. By setting the number of retaining columns 21 to four, two are hinged on each side of the two sides of the main frame body 1 through the rotating connecting block 20, so that the folding frame 13 is more stable and not easy to disengage during the rotation process.

[0050] Furthermore, as another specific implementation of the utility model, the utility model provides a traction-type special leveling machine for irrigated land.

[0051] Specifically, Figure 1 -

[0053] In the utility model, the device can be smoothly connected with other agricultural machines.

[0054] Furthermore, as another specific implementation of the utility model, the utility model provides a traction-type special leveling machine for irrigated land.

[0055] Specifically, Figure 1 -

[0056] Figure 5 As shown, three second dust storage grooves 3 and two first dust storage grooves 2 are penetrated through the top surface of the main frame 1, a main dust shovel 24 is fixedly installed on the rear side of the inner wall of the first dust storage groove 2, and an auxiliary dust shovel 19 is fixedly installed on the inner wall of the second dust storage groove 3.

[0057] In the utility model, a second dust storage trough 3 and a first dust storage trough 2 are provided, and a main dust shovel 24 is fixedly installed on the rear side of the inner wall of the first dust storage trough 2, and an auxiliary dust shovel 19 is fixedly installed on the inner wall of the second dust storage trough 3, so that when the device encounters soil blocks that cannot be pushed away by the main dust pushing plate 22 and the auxiliary dust pushing plate 18 during the forward movement, the soil blocks will be scooped up by the triangular auxiliary dust shovel 19 and the main dust shovel 24, and enter the second dust storage trough 3 and the first dust storage trough 2. When encountering a soil pit, the dust in the second dust storage trough 3 and the first dust storage trough 2 will fall down again, thereby improving the quality and efficiency of land leveling.

[0058] Furthermore, as another specific implementation of the utility model, the utility model provides a traction-type special leveling machine for irrigated land.

[0059] Specifically, Figure 1 -

[0060] Figure 5 As shown, a third dust storage groove 17 is penetrated through the top surface of the folding frame 13, and a main dust shovel 24 is also installed on the inner wall of the third dust storage groove 17. A main dust pushing plate 22 is integrally formed at the front end of the main frame body 1, and an auxiliary dust pushing plate 18 is fixedly connected to the front end of the folding frame 13. An auxiliary dust shovel 19 is also fixedly installed at the front end of the outer wall of the folding frame 13.

[0061] In the utility model, a main dust shovel 24 is also installed on the inner wall of the third dust storage tank 17, and an auxiliary dust shovel 19 is also fixedly installed on the front end of the outer wall of the folding frame 13, so that the quality and efficiency of land leveling can also be increased when the folding frame 13 is working.

[0062] Furthermore, as another specific implementation of the utility model, the utility model provides a traction-type special leveling machine for irrigated land.

[0063] Specifically, Figure 3 As shown, there are two hinged plates 23, and the two hinged plates 23 are hinged to the connecting frame 9 at the same time. A retaining rod 25 is fixedly installed inside the connecting frame 9, and a reinforcing rod 10 is fixedly installed on the top surface of the retaining rod 25. The other end of the reinforcing rod 10 is fixedly connected to the docking rod 11.

[0064] In the utility model, by setting the number of hinged plates 23 to two, the two hinged plates 23 are hinged to the connecting frame 9 at the same time, so that the connection between the main frame 1 and the connecting frame 9 is more stable and not easy to separate. By setting the retaining rod 25 and the reinforcement rod 10, and setting the other end of the reinforcement rod 10 to be fixedly connected with the docking rod 11, the overall structure of the connecting frame 9 is more stable and not easy to be damaged.

[0065] Furthermore, as another specific implementation of the utility model, the utility model provides a traction-type special leveling machine for irrigated land.

[0066] Specifically, Figure 1 -

[0067] Figure 5 As shown, arc blocks are fixedly installed on both sides of the U-shaped frame 12, two second cylinders 15 are rotatably connected to the top of the U-shaped frame 12 through the arc blocks, a protrusion is fixedly installed on the rear side of the top surface of the U-shaped frame 12, and the first cylinder 14 is fixedly connected to the rear side of the protrusion.

[0068] In the utility model, a first cylinder 14 is fixedly connected to the rear side of the protrusion by fixing a protrusion on the rear side of the top surface of the U-shaped frame 12, so that the first cylinder 14 has an inclination in the initial state, so that the moving wheel 8 can be folded smoothly.

[0069] Working principle: When in use, first connect with other agricultural machinery through the docking port 6 opened at the front end of the tripod 5, and then drive the device to move through the agricultural machinery. During the movement of the device, the device can be adjusted according to the road conditions. When the device is just starting, it is generally a cement ground. At this time, the entire device can be driven to move by relying on the moving wheels 8 in conjunction with agricultural machinery. When the device enters the farmland, the user can start the first cylinder 14 to make the first cylinder 14 begin to shrink. After the first cylinder 14 begins to shrink, the docking rod 11 connected to one end of the first cylinder 14 will be driven by the first cylinder 14, and the docking rod 11 is installed on the top surface of the connecting frame 9, and the connecting frame 9 is rotatably connected to the main frame body. 1, therefore, after the first cylinder 14 drives the docking rod 11 to retract, the connecting frame 9 will gradually move up during the retraction process until the two moving wheels 8 are completely off the ground. At this time, the main frame 1 and the folding frame 13 can be used to level the land. When the device is used in winter, frozen soil is often encountered. If the device is forcibly used on frozen soil, it is easy to cause the device to be damaged. At this time, the user can start the first cylinder 14, and push the docking rod 11 through the first cylinder 14, so that the moving wheel 8 gradually contacts the ground, thereby reducing the resistance to forward movement. At the same time, without making the moving wheel 8 fully support the device, the device can still level the land during the movement without being damaged.

[0070] When the device completes leveling a piece of land, the first cylinder 14 can be started again, so that the first cylinder 14 pushes the docking rod 11 to the initial position. At this time, the moving wheel 8 is completely on the ground. In this way, after the agricultural machinery drives the device to the concrete ground, the device will not be easily damaged, and the ground is also protected.

[0071] By setting up the mobile components, the device body will not be easily damaged when the device is running on the cement ground, and the device will not cause damage to the road surface. This protects the device while also protecting the road surface, thereby increasing the practicality of the device.

[0072] By setting up mobile components, the leveling part of the device can be raised and lowered, so that the device can be freely raised and lowered according to the degree of thawing of the land during operation, so that the device can have excellent leveling ability even when facing frozen soil, and at the same time can improve the leveling efficiency.

[0073] When the device encounters a smaller piece of land during use, the user can start the two second cylinders 15. After the second cylinders 15 are started, they will drive the mounting block 16 to retract. The mounting block 16 is fixedly mounted on the folding frame 13. The folding frame 13 is rotatably connected to the main frame 1 through the retaining column 21. Therefore, after the second cylinder 15 drives the mounting block 16 to retract, the folding frame 13 itself will rotate, thereby moving away from the ground and reducing the lateral footprint of the device, so that the device can be used more freely in small farmlands.

[0074] In addition, during use, the user can also start the second cylinder 15 on one side separately to fold the folding frame 13, so that the area change of the device is more flexible and can be used more conveniently in land of various areas.

[0075] By setting up a folding component, the device can be freely folded according to the size of the plot during use, which increases the flexibility of the device and allows the device to adapt to plots of different sizes and shapes. The same equipment can be used in a variety of different land leveling projects, thereby improving the utilization rate of the equipment. At the same time, it can be freely adjusted according to the size of the plot, reducing the time and manpower for repetitive operations and improving work efficiency. In addition, since the folding function does not require too much manual participation, it can be freely adjusted according to the size of the plot, reducing the time for manual adjustment and setting, and reducing labor costs.

[0076] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
