[0044] Furthermore: the grabbing arm 11 is provided with a driving device in its base.

[0045] Furthermore: a mounting hole connected to the tractor head is provided in the middle of the lower end of the front of the frame 1.

[0046] Furthermore: two sets of crawler devices are arranged at the lower end in front of the frame 1, and are powered by a traction locomotive.

[0048] Furthermore: the upper end of the working material box 8 is open in the middle, and three opening surfaces thereof are open to the outside.

[0049] The working process is as follows:

[0050] 1. Preparation before work: The mounting device is connected to the tractor head, and the grabbing arm 11 grabs a number of block-shaped or cylindrical straw materials from the straw yard and puts them into the waiting box 12, and at the same time puts one or two rolls of straw materials into the working box 8, and each roll of straw materials presses the material pressing rod 903; and retracts the supporting legs under the rear end of the mounting device.

[0051] 2. Start working: The front of the vehicle starts to pull the device forward on the working surface of the sand. At this time, the vehicle speed is slow, the rectangular rack mechanism 3 is located at the end of the arc rack mechanism 2 close to the rear of the vehicle, and the angle of the angle device is the largest; at the same time, the two groups of twisting shafts 801 at the lower opening of the working material box 8 rotate in one forward direction and the other reverse direction, and the multiple cones 803 on the circumferential surfaces of the two groups of twisting shafts 801 transport the straw material downward and fall on the sandy ground; at the same time, the workbench device starts to move from one end of the rectangular rack mechanism 3 to the other end.

[0052] A set of pressing mechanisms 10 with the same structure and function are respectively arranged on the outer walls of the two sides of the working material box 8. When the pressing mechanism 10 on one side starts to work, the rack bar 1007 moves downward and drives the roller 1004 to press the straw material into the sand. At the same time, the moving mechanism 4 starts to move from one end of the rectangular rack mechanism 3 to the other end. When it reaches the limit switch 304, the moving mechanism 4 starts to move in the opposite direction. At the same time, the rack bar 1007 of the pressing mechanism 10 on one side that is in working state rises to the initial state and stops working. At the same time, the pressing mechanism 10 on the other side starts to do the same work of pressing the straw material.

[0053] When the workbench device reaches the limit switch 305 at the other end of the rectangular rack mechanism 3, a small working cycle ends. At this time, a "V"-shaped sand enclosure frame with an angle of 90° is formed on the sand working surface. After the workbench device reciprocates along the rectangular rack mechanism 3, a first row of several "V"-shaped sand enclosure frames with an angle of 90° can be formed on the working sand surface. At this time, it is only necessary to adjust the starting point of the workbench device and repeat the above working process from the other side of the rectangular rack mechanism 3 to form a row of several "V"-shaped sand enclosure frames with an angle of 90° on the second row of the working sand surface; Figure 6 As shown, the thin dotted line is the first row of working surfaces, and the thick dotted line is the second row of working surfaces. So far, two rows of half "V"-shaped sand enclosures with an angle of 90° can form a complete and standard square sand enclosure. One large working cycle ends and the next large working cycle begins.

[0054] During operation: the power of the two sets of pressing mechanisms 10 is connected to the pressure sensing device to ensure that the pressing depth of the roller 1004 is maintained on the complex and uneven sandy working surface.

[0055] During work: With the influence of the complex, uneven sand working surface and the speed of the vehicle, the angle between the rectangular rack mechanism 3 and the arc rack mechanism 2 can be adjusted to ensure that each standard square sand frame is not deformed and the quality is guaranteed.

[0056] During operation: as the vehicle speed changes, the rotation speeds of the two groups of twisting shafts 801 are adjusted to ensure the stability of the amount of straw material discharged and to ensure quality.

[0057] During operation: During the unloading process of the straw material, the material pressing rod 903 will be driven to rotate along the two sets of rollers 901. When reaching the limit switch 904, a loading instruction is issued to the grabbing arm 11. The grabbing arm 11 grabs the straw material roll from the waiting box 12 and puts it into the working box 8 to ensure continuous loading.

[0058] The present invention requires a control system to accurately control the rotation speed of each motor, so that the user can complete the overall control of the sand fixation work in the cab of the tractor head, and is suitable for promotion and application.

[0059] The above are only preferred embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes and substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the scope defined in the claims.
