Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, specifically relating to an adjustable soil covering and compaction device for a seeder. Background Technology

[0002] The soil covering and compaction device of a seeder is typically used during crop planting to cover the seeds with soil and gently compact the soil to ensure successful seed germination. In existing technologies, the soil covering discs of these devices are generally fixed to the seeder, with a fixed spacing between the discs. This lack of flexibility prevents adjustment based on actual sowing conditions.

[0003] Patent application number 202420994852.6 discloses an adjustable soil covering and compaction device for a seeder, including a mounting frame one and a mounting frame two, and an adjustment mechanism. The adjustment mechanism includes a bidirectional threaded rod, the two ends of which are rotatably connected to the mounting frame one and the mounting frame two, respectively. Sleeve blocks are threaded on the opposite threaded sections of the bidirectional threaded rod. Connecting rods are symmetrically hinged at the ends of the sleeve blocks that are close to each other. The connecting rods on the same side are all hinged to the same connecting seat. Soil covering disc one and soil covering disc two are respectively connected at the ends of the connecting seats that are far apart from each other. The adjustment mechanism also includes a limiting plate disposed at the bottom end of the sleeve block.

[0004] The aforementioned adjustable soil compaction device for seeders uses a motor and lead screw to adjust the spacing of the soil compaction discs. However, during use, soil can easily splash into the motor along the heat dissipation grooves, causing damage to the motor. Furthermore, the motor lacks axial positioning after the soil compaction disc spacing is closed, and the soil compaction discs are squeezed by the soil, causing the sleeve block to move along the lead screw, resulting in loosening of the soil compaction discs during use and poor stability after the soil compaction disc spacing is adjusted. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an adjustable soil covering and compaction device for a seeder. This adjustable soil covering and compaction device aims to solve the technical problems of existing technologies, such as soil easily splashing into the motor along the heat dissipation groove during use, causing damage to the motor, lack of axial positioning of the motor after the soil covering disc spacing is closed, and the soil squeezing of the soil covering disc causing the sleeve block to move in the drive screw, resulting in loosening of the soil covering disc during use, and poor stability after the soil covering disc spacing is adjusted.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an adjustable soil covering and compaction device for a seeder, including a mounting rod and a first mounting frame and a second mounting frame welded and fixed to both ends of the mounting rod. A rotating rod is mounted in the first mounting frame through a bearing, and sliding plates are slidably inserted into both ends of the first mounting frame. Soil covering plates are welded and fixed to both sliding plates. A screw for driving the soil covering plate to move is threaded into both ends of the rotating rod. A knob bolt for axially positioning the rotating rod is installed on the side wall of the first mounting frame.

[0009] When using this technical solution, sliding plates are slidably inserted into both ends of the first mounting frame, and soil covering plates are welded and fixed on both sliding plates. When adjusting the soil covering spacing, the rotating rod is rotated. During the rotation of the rotating rod, the two lead screws move synchronously in the screw holes. During the movement of the lead screws, the two soil covering plates and the soil covering disc move synchronously through the convex plate, thereby adjusting the spacing of the soil covering discs. After adjustment, the knob bolt is tightened so that the knob bolt is inserted into the positioning hole to keep the rotating rod axially positioned, avoiding the situation where the rotating rod rotates after the spacing is adjusted and the soil covering discs become loose, thus improving the stability after the soil covering disc spacing is adjusted. By welding and fixing a second mounting frame to the mounting rod, after the soil covering discs are covered with soil, the leveling main shaft in the second mounting frame drives the leveling block to rotate. During the rotation of the leveling block, the soil after covering with soil is leveled, improving the soil covering effect after sowing.

[0010] Preferably, each of the two soil covering plates is rotatably connected to a rotating shaft, and a soil covering disc is welded and fixed to each of the two rotating shafts.

[0011] Furthermore, the outer wall of the rotating rod is provided with positioning holes in a ring array, and both ends of the rotating rod are provided with threaded holes with the same thread direction.

[0012] Furthermore, the two lead screws are threaded in opposite directions and respectively threaded into two screw holes, and the ends of the two lead screws extending out of the rotating rod are welded and fixed to the convex plate integrally formed on the side wall of the soil cover plate.

[0013] Furthermore, the knob bolt is threaded into the first mounting bracket, and one end of the knob bolt passing through the first mounting bracket is fitted into the positioning hole.

[0014] Furthermore, a leveling spindle is installed in the second mounting bracket, and both ends of the leveling spindle are rotatably mounted in the second mounting bracket via bearings.

[0015] Furthermore, leveling blocks are welded and fixed at equal intervals to the outer wall of the leveling spindle, the mounting rod is inclined, and the leveling blocks are at the same horizontal position as the bottom end of the soil covering plate.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features sliding plates slidably inserted at both ends of a first mounting frame, with soil covering plates welded and fixed to both sliding plates. When adjusting the soil covering spacing, rotating a rotating rod causes two lead screws to move synchronously in screw holes. During the movement of the lead screws, the two soil covering plates and soil covering discs move synchronously through a convex plate, thereby adjusting the spacing of the soil covering discs. After adjustment, tightening the knob bolts inserts them into the positioning holes to keep the rotating rod axially positioned, preventing the soil covering discs from loosening due to rotation of the rotating rod after spacing adjustment, thus improving the stability of the soil covering disc spacing after adjustment.

[0019] By welding and fixing a second mounting frame to the mounting rod, after the soil covering plate is covered with soil, the leveling main shaft in the second mounting frame drives the leveling block to rotate. During the rotation, the leveling block levels the soil after the soil covering, thus improving the soil covering effect after sowing. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is an adjustable soil covering and compaction device for a seeder, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the device includes a mounting rod 1 and a first mounting bracket 10 and a second mounting bracket 11 welded and fixed to both ends of the mounting rod 1. A rotating rod 12 is mounted in the first mounting bracket 10 via bearings, and sliding plates 6 are slidably inserted into both ends of the first mounting bracket 10. Soil covering plates 5 are welded and fixed onto both sliding plates 6. Screws 7 for moving the soil covering plates 5 are threaded into both ends of the rotating rod 12. A knob bolt 15 for axially positioning the rotating rod 12 is installed on the side wall of the first mounting bracket 10.

[0028] Two soil-covering plates 5 are each rotatably connected to a rotating shaft 8, and a soil-covering disc 4 is welded and fixed to each of the two rotating shafts 8. The outer wall of the rotating rod 12 has positioning holes 13 arranged in a ring array, and both ends of the rotating rod 12 have screw holes 14 with the same thread direction. Two lead screws 7 with opposite thread directions are threaded into the two screw holes 14 respectively, and the ends of the two lead screws 7 extending out of the rotating rod 12 are welded and fixed to the protruding plates 9 integrally formed on the side wall of the soil-covering plate 5. A knob bolt is threaded into the first mounting bracket 10, and the knob bolt 15 passes through... One end of the first mounting bracket 10 is inserted into the positioning hole 13. Covering plates 5 are welded and fixed on both sliding plates 6. When adjusting the soil covering distance, the rotating rod 12 is rotated. During the rotation of the rotating rod 12, the two lead screws 7 move synchronously in the screw hole 14. During the movement of the lead screws 7, the two covering plates 5 and the soil covering disc 4 are moved synchronously through the convex plate 9, thereby adjusting the distance of the soil covering disc 4. After adjustment, the knob bolt 15 is tightened so that the knob bolt 15 is inserted into the positioning hole 13 to keep the rotating rod 12 axially positioned.

[0029] The second mounting frame 11 is equipped with a leveling spindle 3. Both ends of the leveling spindle 3 are rotatably mounted in the second mounting frame 11 via bearings. Leveling blocks 2 are welded and fixed at equal intervals on the outer wall of the leveling spindle 3. The mounting rod 1 is set at an angle. The leveling blocks 2 and the bottom of the covering plate 4 are at the same horizontal position. After the covering plate 4 is covered with soil, the leveling spindle 3 in the second mounting frame 11 drives the leveling blocks 2 to rotate. During the rotation, the leveling blocks 2 level the soil after covering, which improves the soil covering effect after sowing.

[0030] Working Principle: When using the device of this technical solution, the spacing of the covering discs 4 is adjusted according to planting needs before covering with soil. During the adjustment of the covering spacing, the rotating rod 12 is rotated. As the rotating rod 12 rotates, the two lead screws 7 move synchronously in the screw holes 14. During the movement of the lead screws 7, the two covering plates 5 and the covering discs 4 move synchronously through the convex plate 9, thereby adjusting the spacing of the covering discs 4. After adjustment, the knob bolt 15 is tightened, inserting into the positioning hole 13 to keep the rotating rod 12 axially positioned. This prevents the covering discs 4 from loosening due to rotation of the rotating rod 12 after spacing adjustment, improving the stability of the covering discs 4 after spacing adjustment. After the covering discs 4 are covered with soil, the leveling main shaft 3 in the second mounting frame 11 drives the leveling block 2 to rotate. During rotation, the leveling block 2 levels the soil after covering, improving the soil covering effect after sowing. All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
