Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and in particular to a soil loosening device for agricultural planting. Background Art

[0002] Greenhouse planting is a very important method in agricultural planting. Ridge cultivation is usually adopted in the greenhouse, which can improve air permeability and root growth, and is also conducive to water management. However, due to the long-term coverage of plastic film in the greenhouse environment, the soil is prone to problems such as compaction and decreased air permeability. At this time, loosening the soil is necessary. Loosening the soil can break the plow bottom layer, enhance the capillary action of the soil, and promote the uniform diffusion of fertilizer.

[0003] However, the existing device has poor protection for the ridges when loosening the soil, and it is easy to turn the soil blocks into the ridge ditches, which is more likely to cause the ridges to collapse. In addition, it is not convenient to evenly distribute the turned soil blocks when loosening the soil, resulting in insufficient looseness of the soil particles and low soil permeability. Summary of the Invention

[0004] In order to overcome the shortcomings of the background technology, the present invention provides a soil loosening device for agricultural planting, which has stronger protection for field ridges, more uniform soil loosening, looser soil and higher air permeability.

[0006] In a preferred embodiment of the present invention, the plowing mechanism includes a driving motor, which is slidably connected to one side of the rotating table, and a transmission component 1 is fixedly connected to both sides of the driving motor, and the transmission component 1 is connected to the electric lifting rod, and the transmission component 1 is connected to the output shaft of the driving motor. A rotating shaft is provided between the two transmission components 1, and a plurality of plowing knives are fixedly connected to the rotating shaft. Two limit frames are fixedly connected to the supporting plate, and an arc groove is provided on the limit frame. Both sides of the push frame are respectively located in the arc grooves on the two limit frames, and two vertical plates are fixedly connected to the supporting plate, and a movable card rod is slidably connected between the two vertical plates, and an inclined surface is provided on one side of the movable card rod, and a reset spring is connected between the movable card rod and the vertical plate.

[0007] In a preferred embodiment of the present invention, the soil fixing mechanism includes two baffles, which are respectively connected to the two sides of the support plate in a sliding manner, and a return spring is connected between the baffles and the support plate. Extrusion round rods are fixedly connected to both sides of the rotating table, and the extrusion round rods are in contact with the baffles. One side of each baffle is fixedly connected to a guide rod, and a guide groove is provided on the guide rod. Fixed plates are fixedly connected to both sides of the support plate, and each fixed plate is slidably connected to a movable support rod, and one side of the movable support rod is located in the guide groove of the guide rod, and one side of each movable support rod is fixedly connected to a soil fixing plate.

[0008] The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame, and the cam is mounted on a link cam.

[0009] In a preferred embodiment of the present invention, it also includes a soil shaking mechanism, which is arranged on the movable support rod, and the soil shaking mechanism is used to loosen the soil ridges by vibration. The soil shaking mechanism includes two connecting rods, and the two connecting rods are respectively fixedly connected to the two movable support rods, and the lower part of each connecting rod is slidably connected to a movable contact rod, and a pressure spring is connected between the movable contact rod and the connecting rod, and one side of each movable contact rod is fixedly connected to a knocking rod, and the knocking rod contacts the side of the soil fixing plate, and the upper part of each connecting rod is fixedly connected to an inclined rod, and each inclined rod is rotatably connected to a driven magnetic disk, the moving contact rod contacts one side of the driven magnetic disk, and each side of the driven magnetic disk is fixedly connected to two inclined strips, and both ends of the rotating shaft are fixedly connected to an active magnetic disk, and the active magnetic disk and the driven magnetic disk have opposite magnetic properties.

[0010] Compared with the prior art, the present invention has the following advantages: 1. When the plow blade is lowered to loosen the soil, the two soil-fixing plates will move horizontally toward each other and squeeze the soil on both sides of the ridge. In this way, after the soil in the ridge is loosened, the turned-over soil blocks are not easy to fall into the ditch. The two soil-fixing plates clamp the two sides of the ridge, which can also prevent the ridge from collapsing when loosening the soil.

[0011] 2. When the rotating shaft drives the plow blade to rotate to loosen the soil on the ridges, the rotating shaft will drive the rotating long rod to rotate rapidly through the acceleration component. The rotation of the rotating long rod will drive the spiral piece to rotate together. The rotation of the spiral piece will push some clods of soil on both sides toward the middle and gather them together. The rotation of the rotating long rod will drive the bevel gear 1 to rotate through the transmission component 2, and then drive the curved rod to rotate. The rotation of the curved rod will drive the guide plate and the sweeping rod to swing back and forth. The reciprocating swing of the sweeping rod will sweep away and disperse the clods of soil pushed to the middle by the two spiral pieces again, so that the clods of soil turned up during loosening are evenly dispersed.

[0012] 3. The rotating shaft drives the active magnetic disk and the driven magnetic disk to rotate together. The rotation of the driven magnetic disk will drive the inclined surface to rotate. The rotation of the inclined surface will squeeze the moving contact rod to move horizontally for a distance, causing the pressure spring to compress. The horizontal movement of the moving contact rod will drive the knocking rod to move horizontally for a distance away from the soil fixing plate. Then, after the moving contact rod is out of contact with the inclined surface, the pressure spring will quickly reset, driving the moving contact rod and the knocking rod to quickly reset. The knocking rod will knock on the side of the soil fixing plate when it quickly resets. The two inclined surfaces repeatedly squeeze the moving contact rod, driving the knocking rod to continuously knock on the side of the soil fixing plate, so that the soil fixing plate transmits the vibration generated by the knocking to the ridge clamped in the middle. Plowing and turning the soil while vibrating can reduce the resistance to turning the soil, making it easier to turn over the soil blocks, and can also make the turned over soil blocks looser, thereby increasing the air permeability of the soil.

[0025] The soil-fixing mechanism includes two baffles 81, which are respectively connected to the two sides of the support plate 1 in a sliding manner, and a return spring 82 is connected between the baffles 81 and the support plate 1.

[0026] The plough blade 74 is lowered after the driving motor 71 is started and the movable clamping rod 78 is pulled so that the pushing frame 6 is no longer stuck. Then the plough blade 74 is lowered and the driving motor 71 drives the rotating shaft 73 and the plough blade 74 to rotate through the transmission component 1 72 to loosen the soil on the ridge. Then the device is pushed forward to continue loosening the soil. At first, when the plough blade 74 is not lifted, the two squeezing rods 83 squeeze the blocking rod 81. At the same time, when the push frame 6 is pushed downward, the plow blade 74 will be lifted upward, and the two soil fixing plates 87 will be moved to both sides, which makes it easier for the operator to move the device in the working area.

A straight groove is opened on the guide plate 911, and the lower portion of the curved rod 99 passes through the straight groove on the guide plate 911.

[0028] When the rotating shaft 73 drives the plow blade 74 to rotate to loosen the soil on the ridges, the rotating shaft 73 will drive the rotating long rod 92 to rotate rapidly through the acceleration component 93. The rotation of the rotating long rod 92 will drive the spiral piece 94 to rotate together. The rotation of the spiral piece 94 will push some clods of soil on both sides toward the middle and gather them together. The rotation of the rotating long rod 92 will drive the bevel gear 1 96 to rotate through the transmission component 2 97, and then drive the curved rod 99 to rotate. The rotation of the curved rod 99 will drive the guide plate 911 and the sweeping rod 910 to swing back and forth. The reciprocating swing of the sweeping rod 910 will sweep away and disperse the clods of soil pushed to the middle by the two spiral pieces 94 again, so that the clods of soil turned up when loosening the soil are evenly dispersed.

[0029] Example 3 On the basis of Example 2, Figure 7-8 As shown, it also includes a soil shaking mechanism, which is arranged on the mobile support rod 86. The soil shaking mechanism is used to loosen the soil ridges by vibration. The soil shaking mechanism includes two connecting rods 101, and the two connecting rods 101 are fixedly connected to the two mobile support rods 86 respectively. The lower part of each connecting rod 101 is slidably connected to a moving contact rod 102, and a pressure spring 103 is connected between the moving contact rod 102 and the connecting rod 101. A knocking rod is fixedly connected to one side of each moving contact rod 102. Rod 104, the knocking rod 104 is in contact with the side of the soil-fixing plate 87, each of the connecting rods 101 is fixedly connected to the upper part of an inclined rod 105, each of the inclined rods 105 is rotatably connected to a driven magnetic disk 106, the movable contact rod 102 is in contact with one side of the driven magnetic disk 106, each of the driven magnetic disk 106 is fixedly connected to one side with two inclined strips 107, and both ends of the rotating shaft 73 are fixedly connected to an active magnetic disk 108, and the active magnetic disk 108 has opposite magnetic properties to the driven magnetic disk 106.

[0030] When the plow blade 74 is lowered from the raised state along with the rotating table 4 and plows the land, the rotating shaft 73 will drive the active magnetic disk 108 to swing downward together, and the active magnetic disk 108 has opposite magnetic properties to the driven magnetic disk 106. When the plow blade 74 and the rotating shaft 73 are in place, the active magnetic disk 108 is opposite to the driven magnetic disk 106 and is coupled by magnetic force. Then the rotating shaft 73 drives the active magnetic disk 108 and the driven magnetic disk 106 to rotate together. The rotation of the driven magnetic disk 106 will drive the inclined surface 107 to rotate. The rotation of the inclined surface 107 will squeeze the moving contact rod 102 to move horizontally for a distance, so that the pressure spring 103 is compressed, and the horizontal movement of the moving contact rod 102 will drive the knocking The rods 104 move horizontally for a distance away from the soil-fixing plate 87, and then after the moving contact rod 102 loses contact with the inclined surface 107, the pressure spring 103 will quickly reset, driving the moving contact rod 102 and the knocking rod 104 to quickly reset. The knocking rod 104 quickly resets and knocks the side of the soil-fixing plate 87. The two inclined surfaces 107 repeatedly squeeze the moving contact rod 102, driving the knocking rod 104 to continuously knock on the side of the soil-fixing plate 87, so that the soil-fixing plate 87 transmits the vibration generated by the knocking to the field ridge clamped in the middle. Plowing and turning the soil while vibrating can reduce the resistance to turning the soil, making it easier to turn out the soil blocks, and can also make the turned-out soil blocks looser, increasing the air permeability of the soil.
