Description

Technical Field

[0001] This utility model relates to the field of rice sowing technology, specifically to a soil covering device for rice sowing. Background Technology

[0002] Rice sowing is an important step in the rice cultivation process. After sowing, the soil covering device can effectively cover the seeds and keep the soil moist. This helps reduce soil moisture evaporation, provides a stable humidity environment for rice growth, is conducive to seed germination and growth, and improves soil structure and fertility.

[0003] According to a rice sowing covering device (publication number: CN222108503U) disclosed above, the above application uses two sets of electric telescopic rods A to simultaneously extend and retract, driving the fixed shell B to move within the inner wall of the fixed shell A, thereby changing the distance between the two sets of fixed shells B, thus changing the covering width. This achieves the effect of adjusting the covering width of the rice sowing covering device according to the actual situation when covering rice seeds.

[0004] However, in practical use, this soil covering device has some shortcomings. Specifically, the device filters and screens the crushed soil through a filter frame and a filter screen to ensure the quality and uniformity of the soil covering. However, the filter screen often remains stationary during prolonged use, which causes soil to easily accumulate on its surface. This accumulation not only affects the smooth falling of the soil but may also clog the filter screen, thus impacting subsequent soil covering work. Utility Model Content

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a soil covering device for rice sowing, including a base 1, a box 2 on the top of the base 1, a support rod 3 fixed on the surface of the box 2, the bottom of the support rod 3 fixed to the surface of the base 1, and a crushing component 6 and a dispersing component 7 arranged on the surface and inside of the box 2. The crushing component 6 includes: a fixing frame 63 and a motor 64; the dispersing component 7 includes: a pulley 70, a pulley 71, a rotating rod 72, a cam 73, a fixing plate 74, a spring 75, a sieve plate 76, a linkage 77, a connecting frame 770, a stabilizing rod 771, a short rod 772, a rotating cylinder 773, an arc groove 774, and a swing rod 775.

[0026] A pulley 70 is fixed to the output shaft surface of a motor 64. A pulley 71 is rotatably connected to the surface of the housing 2. A rotating rod 72 is fixed to the inner side of the pulley 71, passing through the housing 2 and rotatably connected to it. A cam 73 is fixed to the end of the rotating rod 72 away from the pulley 71. A fixing plate 74 is fixed to the inner wall of the housing 2. A spring 75 is fixed to the bottom of the fixing plate 74. A sieve plate 76 is fixed to the bottom of the spring 75 and slidably connected to the inner wall of the housing 2. The dispersing assembly 7 also includes a linkage 77, which includes a connecting frame 770 fixed to the inner wall of the housing 2. A stabilizing rod 771 is fixed to the surface of the connecting frame 770. A rotating cylinder 773 is slidably connected to the surface of the stabilizing rod 771. The top of the rotating cylinder 773 passes through the sieve plate 76 and rotatably connected to it. An arc is formed on the inner side of the rotating cylinder 773. The curved groove 774 has a short rod 772 fixed to its surface on the stabilizer rod 771. The end of the short rod 772 away from the stabilizer rod 771 extends into the curved groove 774, and the surface of the short rod 772 abuts against the inner wall of the curved groove 774. The rotating drum 773 has a swing rod 775 fixed to its surface. The surfaces of pulley 1 70 and pulley 2 71 are connected by a belt. The cross-section of the connecting frame 770 is triangular. When the motor 1 64 is working, pulley 1 70 drives pulley 2 71 to rotate through the belt. The rotating rod 72 rotates synchronously, and the cam 73 rotates synchronously. The cam 73 intermittently abuts against the screen plate 76, causing the screen plate 76 to vibrate and prevent soil accumulation. At the same time, when the screen plate 76 moves upward, the rotating drum 773 moves upward, and the surface of the short rod 772 abuts against the inner wall of the curved groove 774, thereby causing the rotating drum 773 to drive the swing rod 775 to rotate synchronously. This allows the accumulated soil to be spread out, further improving the soil passage efficiency and preventing accumulation and blockage.

[0027] A fixing frame 63 is fixed to the surface of the housing 2. A motor 64 is fixed to the surface of the fixing frame 63. A crushing roller 60 is rotatably connected to the inner wall of the housing 2. A gear 61 is rotatably connected to the surface of the housing 2. A fixing rod 62 is provided on the surface of the gear 61. The fixing rod 62 passes through the gear 61 and the housing 2, and is fixedly connected to the gear 61. The end of the fixing rod 62 away from the gear 61 is fixed to the surface of the crushing roller 60. There are two sets of gears 61, crushing roller 60, and fixing rods 62. The output shaft of the motor 64 is fixed to the surface of one set of fixing rods 62. The two sets of gears 61 mesh with each other. When the soil is poured into the housing 2 and the motor 64 is turned on, the gear 61 drives the fixing rod 62 to rotate, and the crushing roller 60 rotates, which can crush the soil. The soil falls through the holes of the housing 2 and the base 1, which facilitates the covering work.

[0028] A fixing frame 8 is fixed to the surface of the housing 2. Two sets of fixing frames 8 are provided, and both sets are symmetrically arranged about the center line of the housing 2. A screw 9 is rotatably connected to the inner wall of one set of fixing frames 8, and a sliding rod 11 is fixed to the inner side of the other set of fixing frames 8. A connecting plate 12 passes through the screw 9 and the sliding rod 11, and the connecting plate 12 is slidably connected to the sliding rod 11. The screw 9 is threadedly connected to the connecting plate 12. A baffle 13 is fixed to the bottom of the connecting plate 12, and the baffle 13 is slidably connected to the bottom of the fixing frame 8. A second motor 10 is fixed to the surface. The output shaft of the second motor 10 passes through the fixed frame 8 and is fixed to the surface of the screw 9. The screw 9 has two opposite threads. A caster 5 is installed at the bottom of the base 1 and a handrail 4 is installed at the top of the base 1. The surfaces of the box 2 and the base 1 are provided with holes. By controlling the forward or reverse rotation of the second motor 10, the connecting plate 12 drives the baffle 13 to move closer or further apart, thereby adjusting the size of the holes in the box 2, which is convenient for covering different sown lands with soil.

[0029] When the soil covering device for rice sowing starts working, soil is poured into the box 2, and motor 64 is turned on at the same time. Gear 61 drives the fixed rod 62 to rotate, which in turn rotates the crushing roller 60 to crush the soil. Simultaneously, while motor 64 is working, pulley 70 drives pulley 71 to rotate via a belt. At this time, the rotating rod 72 rotates synchronously, causing the cam 73 to rotate synchronously. When the cam 73 contacts the surface of the screen plate 76, the screen plate 76 moves upward, compressing the spring 75. When the cam 73 no longer contacts the surface of the screen plate 76, the spring 75 releases, causing the screen plate 76 to return to its original position, thus causing the screen plate 76 to vibrate. Simultaneously, as the screen plate 76 moves upward, the roller 60... When the rotating drum 773 moves upward, the surface of the short rod 772 abuts against the inner wall of the arc-shaped groove 774, causing the rotating drum 773 to drive the swing rod 775 to rotate synchronously. This allows the accumulated soil to be spread out, further improving the soil passage efficiency and preventing accumulation and blockage. The triangular connecting frame 770 prevents soil from accumulating on its surface. The soil falls through the holes in the box 2 and the base 1, facilitating the covering work. By controlling the forward or reverse rotation of the motor 10, the connecting plate 12 can drive the baffle 13 to move closer or further apart, thus adjusting the size of the holes in the box 2, which is convenient for covering different types of sown land.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
