DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Specific implementation method 1: Figure 1-6 As shown, this embodiment describes a deep tillage device for agricultural planting, wherein a hanging ring 2 is fixedly connected to one end of the frame 1, and a walking wheel 3 is provided at the lower end of the frame 1; a deep tillage device 4 is provided at the other end of the frame 1;

[0023] The deep tillage device 4 includes a hydraulic cylinder 41; the fixed end of the hydraulic cylinder 41 is fixedly connected to the upper end of the frame 1, and the free end of the hydraulic cylinder 41 is fixedly connected to a connecting frame 42; the lower end of the connecting frame 42 is fixedly connected to a plow 43; the lower end of the connecting frame 42 is hinged with a connecting rod 44, and the other end of the connecting rod 44 is connected to a rotating device 48; the lower end of the connecting frame 42 is also provided with a T-shaped slide 45, and a slider 46 is provided in the slide 45 to slide with it; the lower end of the slider 46 is fixedly connected to the fixed end of the elastic telescopic rod 47, and the free end of the elastic telescopic rod 47 is connected to the rotating device 48. As the height of the connecting frame 42 decreases, the length of the elastic telescopic rod 47 becomes shorter, and its elasticity increases, so that the force between the rotating device 48 and the soil increases, thereby facilitating the crushing of large-volume soil blocks.

[0024] The frame 1 is provided with a plurality of through holes 11 for the plow 43 to pass through. After the plow 43 is used, it moves upward through the through holes 11, and the through holes 11 can scrape the soil on both sides of the plow 43.

[0025] The rotating device 48 includes a shaft 481; the free end of the elastic telescopic rod 47 is fixedly connected to the shaft 481; the connecting rod 44 is sleeved on the shaft 481 through a bearing; the shaft 481 is also connected to a cylinder 482 through a bearing; and a plurality of holes 483 are provided on the outer circumference of the cylinder 482. After a large volume of soil blocks contacts the cylinder 482, part of the soil that does not contact the outer circumference of the cylinder 482 can enter the cylinder 482 through the holes 483, thereby dividing the large volume of soil blocks into a plurality of small blocks.

[0026] The total coverage area of ​​the perforations 483 on the outer circumferential surface of the cylinder 482 is greater than three quarters of the outer circumferential surface area of ​​the cylinder 482, so as to reduce the contact area between the cylinder 482 and the soil, and prevent the soil that has just been turned from being compacted by the cylinder 482.

[0027] The cylinder 482 is symmetrically arranged on the shaft 481, and one end of the cylinder 482 is hollowed out, and the hollow end of the cylinder 482 faces the side away from the connecting rod 44. The soil entering the cylinder 482 is discharged through the gap between the two cylinders 482.

[0028] The inner wall of the cylinder 482 is fixedly connected with a spiral plate 484 to push the soil block inside the cylinder 482 to move until it is discharged from the cylinder 482.

[0029] Baffles 486 are fixedly connected to both sides of the shaft 481, and a gap is provided between the cylinders 482, and an arc rod 485 fixedly connected to the shaft 481 is provided in the gap between two adjacent cylinders 482 facing the same direction. The gap between the baffle 486 and the outermost cylinder 482 is used for the discharge of soil clods, and the soil clods inside the larger cylinder 482 can also be clamped by the spiral plate 484, so as to be broken by the arc rod 485.

[0030] The spiral plate 484 pushes the soil blocks entering the cylinder 482 toward the hollow end of the cylinder 482 as the cylinder 482 rotates.

[0031] The cross-section of the through hole 483 is circular or rectangular, and the diameter or side length thereof is greater than the width of the gap between two cylinders 482 facing the same direction; the distance between the shaft 481 and the inner wall of the cylinder 482 is greater than the width of the gap between the two cylinders 482.

[0032] A method for using a deep tillage device for agricultural planting, the method comprising the following steps:

[0033] Step 1: Hang the frame 1 on the tractor, then retract the hydraulic cylinder 41 to drive the plow 43 to move downward and insert it into the soil to a required depth;

[0034] Step 2: The frame 1 moves with the tractor, and the plow 43 is used to plow, loosen and turn the soil;

[0035] Step 3: The cylinder 482 crushes the large pieces of soil and allows some of the soil pieces to enter the cylinder 482;

[0036] Step 4: As the cylinder 482 rotates, the soil inside the cylinder 482 moves toward the hollow end of the cylinder 482 and is discharged.

[0037] The working principle of the present invention is as follows: when using the device, the frame 1 is hung on the tractor, and then the hydraulic cylinder 41 is retracted to drive the connecting frame 42 to move downward, so that it drives the plow 43 to move downward and insert into the soil; the depth of the plow 43 inserted into the soil is determined according to the retracted length of the hydraulic cylinder 41; as the connecting frame 42 moves downward, it drives the connecting rod 44 to rotate around the hinge, thereby pushing the rotating device 48 to move in a direction away from the hanging ring 2, and at the same time drives the elastic telescopic rod 47 and the slider 46 to slide along the T-shaped slide groove 45;

[0038] The frame 1 moves with the tractor, and performs plowing, loosening and turning operations through the plow 43;

[0039] During the movement of the rack 1, since the cylinder 482 is in contact with the ground, the cylinder 482 also rotates with the movement of the rack 1 due to friction with the ground. When the cylinder 482 encounters soil blocks during the movement, the outer wall of the cylinder 482 crushes the soil blocks into multiple small soil blocks, and the soil blocks enter the interior of the cylinder 482 through the perforation 483. As the cylinder 482 rotates, the spiral plate 484 inside the cylinder 482 also rotates. The soil blocks are always located at the bottom of the inner wall of the cylinder 482 under the action of gravity, and then the soil blocks are pushed to The hollow end of the cylinder 482 moves until it moves to the gap between the two cylinders 482 and is discharged. When the length of the soil block in the cylinder 482 is greater than the width of the gap, the soil block moves close to the hollow end of the cylinder 482, and the spiral plate 484 and the side wall of the other cylinder 482 clamp the soil block. As the cylinder 482 rotates, the soil block is driven to rotate around the shaft 481 until it contacts the arc rod 485 on the shaft 481 and is cut off by the arc rod 485, thereby further crushing the larger soil block to facilitate subsequent other operations.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0041] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
