Description

Technical Field

[0001] This utility model belongs to the field of seed planting technology, and in particular relates to a soil retaining device for turning over the soil before seed planting. Background Technology

[0002] Before planting seeds, the soil should be turned over. Turning the soil breaks up the compacted soil layer, making the soil loose and creating favorable conditions for the extension of plant roots. Loose soil allows the roots to grow and expand more freely downwards, resulting in more stable rooting.

[0003] During soil turning, if a hand-held rotary tiller is used, the turned soil will be thrown backward. The scattered soil or dust may adversely affect the operator. In order to contain the scattered soil, a soil-blocking device for turning soil before seed planting has been designed. This device can control the soil within a certain range by using upper and rear baffles. At the same time, the fixed-point structure can expand or reduce the coverage area of ​​the rear baffle to better collect the soil and contain the scattered soil, thereby reducing the adverse effects of scattered soil or dust on the operator. Utility Model Content

[0026] Example 2:

[0027] Figure 1-6This invention illustrates a soil-retaining device for tilling soil before seed planting according to an embodiment of the present invention. It includes: upper baffles 2 bolted to the left and right sides of a hand-held rotary tiller 1; a support plate 3 welded to the rear sides of both upper baffles 2; a rear baffle 4 rotatably connected to the bottom of the support plate 3; two support ends 5 welded to the front side of the rear baffle 4, located on the left and right sides of the upper baffles 2 respectively; a square tube 6 rotatably connected to the inner cavity of the support ends 5; a support rod 7 slidably connected to the inner cavity of the square tube 6; a screw hole 8 on the bottom surface of the support rod 7; and multiple round holes 9 on both sides of the square tube 6. The inner cavities of the screw holes 8 and the round holes 9 are threaded together with screws. Bolt 10 has a nut 11 threadedly connected to its surface. The bottom of both upper baffles 2 is fixedly connected to a positioning end 12 by bolts. The top of the support rod 7 is rotatably connected to the inner cavity of the positioning end 12. The inner cavity of the square tube 6 is provided with a fixed point structure 13. The inner cavity of the ring 135 is rotatably connected to a ball bearing 137. The surface of the ball bearing 137 is rotatably connected to the inner cavity of the semi-circular groove 132. The bottom of the rear baffle 4 is rotatably connected to a base plate 14.

[0028] Working principle: When using this utility model, the user unscrews the bolt 10 out of the inner cavity of the screw hole 8 and the round hole 9, thereby releasing the restriction on the position of the square tube 6. Then, the user pulls the rear baffle 4 to make the square tube 6 slide. At this time, the ball bearing 137, supported by the round tube 134, the ring 135 and the spring 136, rolls tightly against the inner cavity of the U-shaped plate 131. As it approaches the semi-circular groove 132, the spring 136 pushes the ball bearing 137 into the inner cavity of the semi-circular groove 132. With the cooperation of the semi-circular groove 132 and the ball bearing 137, the position of the square tube 6 is restricted. Then, the bolt 10 is screwed back into the inner cavity of the screw hole 8 and the round hole 9, thereby fixing the position of the square tube 6 and the support rod 7, and fixing the range of the rear baffle 4. This can cover the spilled soil to reduce the scattered soil or dust and prevent adverse effects on the operator.

[0029] In summary, this soil-blocking device for turning over soil before seed planting, through the combined use of the upper baffle 2 and the rear baffle 4, and with the action of the fixed-point structure 13, can limit and fix the range of the rear baffle 4, thereby achieving the purpose of blocking the scattered soil and reducing the adverse effects of scattered soil or dust on the operators.
