Description

Technical Field

[0001] This utility model relates to the field of soil turning equipment technology, and in particular to a soil turning device with adjustable spacing. Background Technology

[0002] In agricultural production, it is necessary to turn the soil in the fields, so soil turning tools are needed.

[0003] A search revealed that a tillage machine tiller, as announced in CN213306121U, involves mounting sliders and tillage devices on a rotating shaft. The distance between tillage plates is adjusted by changing the number of sliders. However, in actual use, when the distance needs to be adjusted, all sliders and tillage devices mounted on the rotating shaft must be disassembled and reassembled. This adjustment method is time-consuming and labor-intensive, and problems such as missing or damaged parts and inaccurate adjustments may occur during disassembly, leading to reduced work efficiency and tillage quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3An adjustable-spacing soil turner includes a housing 1 and two support frames 8. A rotating shaft 16 is rotatably connected to the inner wall of one side of the housing 1. Multiple movable sleeves 20 are provided on the outer side of the rotating shaft 16. A guide rail 18 is fixed to the top of the rotating shaft 16 by bolts, and the guide rail 18 is slidably connected to the movable sleeves 20. The guide rail 18 not only guides the movable sleeves 20 to move stably, but also allows the movable sleeves 20 to rotate with the rotating shaft 16. A fixed sleeve 17 is fixed to the middle position of the rotating shaft 16 by bolts. One end of each of the 17 and multiple movable sleeves 20 is bolted to a disc plow blade 10. A scraper blade 11 is bolted to the top of the disc plow blade 10. A second bidirectional lead screw 12 is rotatably connected inside the support frame 8. Two second sliders 15 are threaded to the outer side of the second bidirectional lead screw 12. A rotating ring 19 is bolted to the bottom end of each second slider 15 and is rotatably connected to the movable sleeve 20. A second power component is provided on one side of the support frame 8 to drive the second bidirectional lead screw 12 to rotate. The second power component enables the second... The bidirectional lead screw 12 drives the two second sliders 15 to move towards the center, thereby causing the rotating ring 19 to drive the movable sleeve 20 to move along the guide rail 18. At this time, the distance between the two movable sleeves 20 located on the same support frame 8 is adjusted, and consequently the distance between the two disc plow blades 10 located on the same support frame 8 is adjusted. At the same time, the distance between the disc plow blades 10 located on the movable sleeve 20 and the disc plow blades 10 located on the fixed sleeve 17 is changed. The first bidirectional lead screw 9 is rotatably connected to the inner wall of one side of the housing 1. The bottom of the support frame 8 is fixed with the first slider 14 by bolts, and the first slider 14 is threadedly connected to the first bidirectional lead screw 9. The outer side of one side of the housing 1 is provided with a first power component that drives the first bidirectional lead screw 9 to rotate. The first power component causes the first bidirectional lead screw 9 to drive the first sliders 14 to move towards the center, thereby adjusting the distance between the two support frames 8, and consequently causing the two disc plow blades 10 located on the same support frame 8 to move as a whole until they maintain the required distance from the disc plow blades 10 on the fixed sleeve 17.

[0023] In this utility model, it should be noted that the top of the housing 1 is fixed with a telescopic rod 2 by bolts, and the extended end of the telescopic rod 2 is fixed with a base 3 by bolts, which facilitates the connection of the device to an external tillage machine. The fixed rod and the movable rod of the telescopic rod 2 are fixed with screws 7. The height of the base 3 can be adjusted by the cooperation between the telescopic rod 2 and the screws 7. The first power component includes a first motor 4, which is fixed to one side of the outer wall of the housing 1 by bolts. One end of the output shaft of the first motor 4 is fixed to a first bidirectional lead screw 9. The rotation of the first motor 4 causes the first bidirectional lead screw 9 to rotate. The second power component includes a second motor 13, the second... The second motor 13 is fixed to the outer wall of one side of the support frame 8 by bolts, and one end of the output shaft of the second motor 13 is fixed to the second bidirectional lead screw 12. The rotation of the second motor 13 causes the second bidirectional lead screw 12 to rotate. Both ends of the rotating shaft 16 pass through the housing 1 and are fixed with fixing blocks 5 by bolts. The fixing blocks 5 restrict the position of the two ends of the rotating shaft 16. Multiple heat dissipation holes 6 are opened on the upper surface of the housing 1, and the heat dissipation holes 6 are evenly distributed to dissipate the heat inside the housing 1. Multiple reinforcing ribs are fixed to the top outer wall of the housing 1 by bolts, and the reinforcing ribs are fixed to the bottom outer wall of the telescopic rod 2, so that the telescopic rod 2 is more firmly fixed to the housing 1.

[0024] Working principle: When it is necessary to adjust the distance between the disc plow blades 10, the second motor 13 is started first. The rotation of the second motor 13 causes the second bidirectional lead screw 12 to drive the two second sliders 15 to move towards the center respectively, thereby causing the rotating ring 19 to drive the movable sleeve 20 to move along the guide rail 18. At this time, the distance between the two movable sleeves 20 located on the same support frame 8 is adjusted, and thus the distance between the two disc plow blades 10 located on the same support frame 8 is adjusted. At the same time, the distance between the disc plow blades 10 located on the movable sleeve 20 and the disc plow blades 10 located on the fixed sleeve 17 is changed. When it is necessary to adjust the distance between the two support frames 8, the first motor 4 is started. The rotation of the first motor 4 causes the first bidirectional lead screw 9 to drive the first slider 14 to move towards the center respectively, thereby adjusting the distance between the two support frames 8, and thus causing the two disc plow blades 10 located on the same support frame 8 to move as a whole until they maintain the required distance with the disc plow blades 10 on the fixed sleeve 17.

[0025] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
