Description

Technical Field

[0001] The invention relates to the technical field of soil improvement, in particular to agricultural equipment for improving soil. Background Art

[0002] In agricultural planting, soil is one of the main factors for crop planting. After a long period of absorption, the nutrients in the soil will become compacted. Soil compaction will lead to a decrease in air permeability, which is not conducive to the growth of crops and causes crop yield reduction. In order to ensure soil nutrients and the survival rate of crops, agricultural equipment needs to be used regularly to improve the soil.

[0003] The most common soil improvement method now is through chemical improvement, that is, first use tillers and other soil-digging equipment to loosen the compacted soil, and then manually spread fertilizers and various soil conditioners into the soil to improve soil fertility, improve soil structure, eliminate soil pollution, etc.; however, the shape of the crushing wheel at the end of the common tiller is mostly fixed, and the soil density of each area of ​​the compacted soil that needs to be turned is not the same. When the tilling equipment works according to the ordinary tilling method, the crushing rate of the denser soil will be reduced, thereby reducing the penetration quality of subsequent fertilizers and liquid conditioners into the soil, which is not conducive to the soil fully absorbing nutrients.

It is suitable for turning over soil with high compactness, making the crushing effect of turning over the soil more uniform, which is beneficial to the subsequent absorption of liquid improvers.

[0014] 2. In the present invention, when turning over compacted soil, the bent rod that contracts toward the inside of the disc will drive the baffle to separate from the outer wall surface of the ring body, thereby causing the through hole inside the ring body to leak out, and causing the liquid improver accumulated inside the ring body to be discharged from the through hole. On the one hand, the discharged liquid will contact the ground before the digging piece contacts the soil, causing the compacted soil to be locally moistened. At the same time, the outflowing liquid will also flow along the surface of the ring body, causing the digging piece to be soaked, making it easier for the digging piece to dig the soil and achieving a better turning over effect. On the other hand, the outflowing liquid improver can also enter the interior of the soil turned over by the machine at the first time, which is more conducive to the soil's absorption of fertilizer nutrients.

[0021] Furthermore, a shaft body 3 18 is provided inside the machine box 1, and the shaft body 3 18 passes through the machine box 1 and is rotatably connected thereto, rollers 19 are provided at both ends of the shaft body 3 18 and are fixedly connected thereto, a shaft body 4 20 is provided above the shaft body 3 18, and the shaft body 4 20 is fixedly connected to the inner wall of the machine box 1 through a fixing frame, the shaft body 3 18 and the shaft body 4 20 are mutually transmitted through a belt, a bevel gear 1 21 is provided at the end of the shaft body 4 20 and is fixedly connected thereto, a bevel gear 2 22 meshing with the bevel gear 1 21 is provided on one side of the bevel gear 1 21, and the bevel gear 2 22 is located on the outer wall of the main shaft 4 and is fixedly connected thereto; the engine 3 provides power, and the main shaft 4 drives the bevel gear 2 22 and the bevel gear 1 21 for transmission, thereby driving the rollers 19 at both ends of the shaft body 3 18 to rotate, which enables the staff to have a certain auxiliary driving force when pushing the equipment to turn the soil, thereby reducing the labor burden of turning the soil.

[0022] When in use, the rotating shaft of the engine 3 will drive the worm 5 and the worm wheel 6 at the end of the main shaft 4 to transmit, so that the shaft body 7 and its outer wall rotating wheel 8 can rotate, and then the digging piece 9 outside the ring body 803 can be used to turn over the relatively soft soil; when the staff needs to turn over the soil with a high degree of compaction, by pressing the switch 27 on the handle, the electric push rod 10013 will start automatically, and the connecting plate 10012 will drive the sliding rod 10011 and the inclined block 10010 to move forward. The inclined area of ​​the inclined block 10010 will resist the side wall of the arc cavity and push the arc cavity to slide into the inside of the disc 801. During this process, the inclined portion 1008 of the arc cavity will resist each other with the end of the bending rod 1006 inside the disc 801, so that multiple bending rods 1006 are simultaneously moved toward the disc 8 01, until the upper bottom surface of the end of the bending rod 1006 contacts the lower bottom surface of the inclined portion 1008, the contracted bending rod 1006 will drive the connecting tube 1004 to slide downward on the outer wall of the shaft body 1001, and the sphere 1005 located on the inner wall of the connecting tube 1004 will mesh with the internal thread 1002 on the outer wall of the shaft body 1001, thereby causing the digging piece 9 on the outer wall of the shaft body 1001 to rotate until the side wall of the digging piece 9 contacts the side wall of the ring body 803 and stops. At this time, the digging piece 9 has switched its position. In the subsequent continuous rotation of the ring body 803, the contact area between the digging piece 9 and the soil becomes smaller, thereby increasing the force on the soil. It is suitable for turning over soil with high compactness, making the crushing effect of turning over the soil more uniform, which is beneficial to the subsequent absorption of liquid improvers.

[0023] According to the above embodiment, embodiment 2, A barrel 11 for holding a liquid improver is disposed above the machine box 1. The bottom of the barrel 11 is fixedly connected to the machine box 1. A plurality of through holes 12 are disposed inside the ring 803. A wetting unit 13 for driving the liquid in the barrel 11 to flow out from the through holes 12 is disposed on one side of the disc 801. The wetting unit 13 cooperates with the switching unit 10 to wet the area to be turned over before digging. The soil has a certain wetting effect before being turned over, which can reduce the difficulty of digging the soil, and further facilitate the digging blade 9 to turn over the compacted soil. The wetting unit 13 includes a baffle 1301 located on the side wall of the ring body 803, the baffle 1301 blocks the through hole 12, a connecting piece 1302 is provided at the bottom of the baffle 1301 and is fixedly connected thereto, the bottom end of the connecting piece 1302 is fixedly connected to the connecting cylinder 1004, the interiors of the connecting rod 802 and the ring body 803 are both cavity-shaped and interconnected, two vertical cylinders 1303 for the flow of liquid modifier are provided inside the machine box 1, the upper and lower ends of the vertical cylinder 1303 are fixedly connected to the inner wall of the machine box 1, a water pipe 1304 is provided on the outer wall of the arc-shaped cavity and is fixedly connected thereto, the water pipe 1304 passes through the machine box 1 and is connected to the vertical cylinder 1303, the inner wall of the vertical cylinder 1303 is provided with a leak plate 1305 and is fixedly connected thereto, the water pipe 1304 is in the vertical cylinder The end of the outer wall of 1303 is located above the leak plate 1305. The liquid fertilizer inside the barrel 11 will enter the vertical cylinder 1303. A part of it will enter the flow box 17 through the leak plate 1305, and the other part will enter the annular cavity 1007, the disc 801, the connecting rod 802 and the ring body 803 through the water pipe 1304 for accumulation. The flow box 17 is provided at the bottom of the vertical cylinder 1303 and is fixedly connected thereto. The center of the water outlet of the flow box 17 coincides with the vertical center vertical plane of the ring body 803. The liquid improver will enter the flow box 17 through the vertical cylinder 1303 and be discharged from its outlet. The water outlet of the flow box 17 is discharged on the same straight line as the turning area of ​​the digging piece 9, ensuring that the soil can be fully absorbed by nutrients. The outer wall of the main shaft 4 is also provided with a bevel gear three 23 and fixedly connected thereto, one side of the bevel gear three 23 is provided with a bevel gear four 24 meshing therewith, the inner wall of the bevel gear four 24 is provided with a stirring shaft 25 and fixedly connected thereto, the stirring shaft 25 is rotatably connected to the machine box 1, and the outer wall of the stirring shaft 25 is provided with blades 26 for stirring the liquid improver, and the stirring is also fixedly connected to the stirring shaft 25; the rotation of the main shaft 4 can drive the bevel gear three 23 and the bevel gear four 24 to transmit, so that the liquid improver inside the barrel body 11 is always in a stirring state during work, avoiding the phenomenon of fertilizer sinking to the bottom, and making the quality of the fertilizer raw materials absorbed by the soil better.

[0024] When turning over loose soil, the side wall of the baffle 1301 has a certain resisting effect on the side wall of the digging piece 9, and cooperates with the elastic force of the spring 15 inside the fixed tube 16, so that the digging piece 9 in operation has a stable working state; on the other hand, when turning over compacted soil, the bending rod 1006 that shrinks toward the inside of the disc 801 will drive the baffle 1301 to separate from the outer wall surface of the ring body 803, thereby causing the through hole 12 inside the ring body 803 to leak out, so that the liquid improver accumulated inside the ring body 803 is discharged from the through hole 12. On the one hand, the discharged liquid will contact the ground before the digging piece 9 contacts the soil, so that the compacted soil becomes partially moistened. At the same time, the outflowing liquid will also flow along the surface of the ring body 803, so that the digging piece 9 is also soaked, which makes it easier for the digging piece 9 to dig the soil and makes the turning over effect better; on the other hand, the outflowing liquid improver can also enter the inside of the soil turned over by the machine at the first time, which is more conducive to the soil's absorption of fertilizer nutrients.
