DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Figures 1 to 4 Shown is an embodiment of the utility model.

[0021] Embodiment 1:

[0022] like Figure 1 , 2 As shown, a soil turning equipment for agricultural machinery with adjustable soil turning depth includes a top plate 1 and baffles 2 vertically arranged at both ends of the lower side of the top plate 1, a knife shaft 3 is arranged horizontally and rotatably between the two baffles 2, and a plurality of blades 4 are arranged around the knife shaft 3. A motor part 5 for driving the knife shaft 3 to rotate is installed on the upper side of the top plate 1, characterized in that a lifting structure is installed on the outer side of the two baffles 2, and a limit slide 6 is installed on the lower end of the lifting structure; a counterweight structure is detachably installed on the upper side of the top plate 1. By installing the limit slide 6 on the outer side of the two baffles 2, the height of the limit slide 6 is adjusted by the lifting structure to control the depth of the blade 4 inserted into the ground by the limit slide 6 fitting the ground, thereby controlling the soil turning depth. By setting the counterweight structure, when deep plowing some hard soil, the weight of the entire equipment can be increased by means of the counterweight structure, so that the blade 4 can be inserted to a sufficient depth for soil turning. The two ends of the motor part 5 are mounted on the upper side of the top plate 1 through two mounting tubes 22. A motor is mounted in the motor part 5. A transmission shaft is rotatably arranged in one of the mounting tubes 22. One end of the transmission shaft is coaxially connected to the output shaft of the motor in the motor part 5, and the other end is placed on the side of the top plate 1 and connected to the first sprocket 23. The end of the knife shaft 3 located on the same side of the first sprocket 23 is placed on the outside of the baffle 2 and connected to the second sprocket 24. Figure 4 As shown, the first sprocket 23 and the second sprocket 24 are driven by a chain 25, and a protective cover is provided on the chain 25, the first sprocket 23 and the second sprocket 24. A connecting piece 26 for connecting a driving device is provided on the top plate 1, for example, the device is connected to a power vehicle, a tractor head and the like through the connecting piece 26.

[0023] The lifting structure includes a screw rod 8 and an adjustment plate 9. The adjustment plate 9 is installed on the outer side of the baffle 2. A threaded hole matching the screw rod 8 is provided on the adjustment plate 9. The middle part of the screw rod 8 is placed in the threaded hole. One end of the limit slide plate 6 is movably connected to the baffle 2, and the other end is movably connected to the lower end of the screw rod 8. With such a setting, when it is necessary to adjust the soil turning depth, the end of the limit slide plate 6 movably connected to the screw rod 8 is driven to rise or fall by rotating the screw rod 8, thereby controlling the insertion depth of the blade 4 when the limit slide plate 6 is attached to the soil surface.

[0024] The limiting slide plate 6 is arc-shaped, and the convex surface faces downward. A connecting piece 10 is vertically arranged on the upper side of the limiting slide plate 6. The connecting piece 10 is provided with a rotation hole that passes through both sides. A bolt hole is arranged on the outer side of the baffle plate 2. When the rotation hole and the bolt hole are aligned, the rotating bolt 11 is passed through the rotation hole and the bolt hole in sequence to make the connecting piece 10 and the baffle plate 2 rotatably connected. The limiting slide plate 6 is arc-shaped, and the limiting slide plate 6 can slide smoothly on the soil surface when turning the soil. The limiting slide plate 6 has a certain width, which can avoid sinking into the soil or compacting the soil during the turning process. By providing the connecting piece 10 and the rotating bolt 11, the limiting slide plate 6 can rotate around the rotating bolt 11 when the screw rod 8 pushes the limiting slide plate 6.

[0025] A connecting ring 12 is arranged above the limiting slide 6, and the opposite sides of the connecting ring 12 are connected to the upper side of the limiting slide 6 through connecting strips 13. After the lower end of the screw rod 8 passes through the middle hole of the connecting ring 12, a limiting plate 14 is connected between the connecting ring 12 and the limiting slide 6, and the diameter of the limiting plate 14 is larger than the diameter of the middle hole of the connecting ring 12. Through the cooperation between the connecting ring 12 and the limiting plate 14, a good connection can be made with the lower end of the screw rod 8, and at the same time, the screw rod 8 will not be restricted from pushing the limiting slide 6. At the same time, when rising, the limiting slide 6 can be driven to rise by pulling the connecting ring 12 with the help of the limiting plate 14.

[0026] like Figure 1 , 3As shown, the counterweight structure includes a mounting block 15 and a counterweight plate 16. The mounting block 15 is connected to the upper side of the top plate 1. A counterweight groove is provided on one side of the mounting block 15. A locking screw hole 17 connected to the counterweight groove is provided on the top of the mounting block 15. The locking screw hole 17 is threaded and connected to a locking screw 18. The lower end of the locking screw 18 is placed in the counterweight groove, and the upper end is connected to a knob plate 19 above the mounting block 15. When the counterweight plate 16 is placed in the counterweight groove, the lower end of the locking screw 18 is connected to the top of the counterweight plate 16. When planting different crops, some only need shallow plowing to loosen the soil on the surface of the soil. However, for some crops with deep root systems, deep plowing is usually required to loosen the deep soil in order to enable the root system of the crops to grow smoothly. At the same time, fertilizer can be mixed during deep plowing so that the fertilizer deep in the soil can fully meet the growth needs of the crops. In order to meet the needs of deep plowing and shallow plowing at the same time, the deadweight of the equipment of the utility model is limited to avoid poor control during shallow plowing. Therefore, a counterweight structure is used to achieve deep plowing requirements. By taking the counterweight plate 16 out of or putting it into the counterweight slot, the deadweight of the entire equipment can be controlled, which is conducive to the blade 4 being inserted deep enough during deep plowing to achieve deep plowing. By providing a locking screw 18, the counterweight plate 16 can be supported by the locking screw 18 to make the counterweight plate 16 firmly installed in the counterweight slot, thereby preventing the counterweight plate 16 from falling off during use. Generally, the counterweight structure is provided on the upper side of the top plate 1 near both ends, which can facilitate the control of the insertion depth of the blades 4 at both ends.

[0027] The side of the end of the counterweight plate 16 is provided with a handle hole 20 that passes through both sides, and the upper side of the mounting block 15 is provided with a notch 21 that is connected to the counterweight slot. By providing the handle hole 20, it is convenient for the operator to hold the counterweight plate 16 through the handle hole 20 to achieve the installation and removal of the counterweight plate 16.
