Description

Technical Field

[0001] The utility model relates to the field of agricultural tools, in particular to an agricultural soil loosening and fertilizing device. Background Art

[0002] Planting is one of the main components of agriculture. Planting is the cultivation of various crops to obtain plant products. Before planting, the soil needs to be loosened and fertilized. The soil contains water and nutrients. The depth of loosening the soil has many effects on crops, including increasing yields, improving root growth, and enhancing soil fertility.

[0003] After searching, the Chinese patent announcement number is CN216700908U, which discloses a loosening device for agricultural soil fertilizer application. The patent uses a roller to move the device. At this time, the loosening roller loosens the soil, and the roller drives the rotating shaft to rotate. During the rotation, the rotating shaft drives the second gear to rotate. The second gear engages with the first gear to drive the round rod to rotate. The round rod drives the roller to spread the fertilizer in the fertilizer trough onto the soil. There are certain problems with this device: the distance between the loosening roller and the soil cannot be adjusted according to the soil quality and crop type, which may affect the root growth environment of the crop, thereby affecting the crop yield.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figure 1-Figure 5As shown, an agricultural soil loosening and fertilizing device includes a carrier platform 101, a handle bar 103 is fixedly connected to one side of the top of the carrier platform 101, a fertilizer box 102 is fixedly connected to the top of the carrier platform 101, an adjustment mechanism is provided at the bottom of the carrier platform 101, and the adjustment mechanism is located on the side of the fertilizer box 102 close to the handle bar 103. The adjustment mechanism includes a fixing frame 401, and the fixing frame 401 is fixedly connected to the bottom of the carrier platform 101. Symmetrical threaded rods 402 are rotatably connected to the front and rear of the carrier platform 101, and the threaded rods 402 are threadedly connected to lifting blocks 404. The bottoms of the symmetrical lifting blocks 404 are fixedly connected to fixing plates 405. A plurality of loosening rakes 502 are provided between the front and rear symmetrical fixing plates 405, and a connecting belt 403 is connected to the top of the front threaded rod 402. The connecting belt 403 is connected to the top of the rear threaded rod 402, and the top of the supporting platform 101 is rotatably connected to the turntable 6. The bottom of the turntable 6 is fixedly connected to the top of the front threaded rod 402. Different crops have different requirements for soil depth. In order to ensure the best effect of crop planting, certain adjustments are required. The rotating turntable 6 drives the symmetrical threaded rods 402 to move synchronously through the connecting belt 403. The threaded rods 402 are threadedly matched with the lifting block 404, so that the lifting block 404 and the fixed frame 401 slide up and down, thereby adjusting the distance between the lifting block 404 and the supporting platform 101, so that the lifting block 404 drives the fixed plate 405 to move up and down, thereby adjusting the distance between the loosening rake 502 and the supporting platform 101, and changing the loosening depth of the loosening rake 502, which is more practical.

[0025] Symmetrical fixed rods 201 are fixedly connected to both sides of the bottom of the supporting platform 101. The end of the fixed rod 201 away from the supporting platform 101 is rotatably connected to the axle 202. Both ends of the axle 202 axially away from the fixed rod 201 are fixedly connected to wheels 8. A belt 203 is connected to the axle 202. Fertilizer enters the movable tube 302 through the fixed tube 301. When the supporting platform 101 is pushed to move, there is friction between the ground and the wheel 8, so that the wheel 8 drives the axle 202 to rotate, and at the same time, the axle 202 drives the belt 203 to move.

[0026] A movable rod is rotatably connected between the front and rear symmetrical fixed plates 405, and multiple loosening rakes 502 are fixedly installed on the movable rod and arranged equidistantly along the axial direction of the movable rod. The front end of the front fixed plate 405 is fixedly connected to a motor 501, and the output shaft of the motor 501 is fixedly connected to the movable rod. The motor 501 drives the movable rod to rotate, so that the movable rod drives the multiple loosening rakes 502 to rotate and turn over the land, making it easier to mix the fertilizer with the soil.

[0027] A fixed pipe 301 is fixedly connected to the bottom of the supporting platform 101 . The fixed pipe 301 is communicated with the inside of the fertilizer box 102 . The fixed pipe 301 is located below the downwardly inclined end of the bottom of the fertilizer box 102 .

[0028] Symmetrical hollow tubes are fixedly connected to the front and rear ends of the fixed tube 301. The end of the symmetrical hollow tube away from the fixed tube 301 is rotatably connected to the movable tube 302. The movable tube 302 has multiple through holes along the circumferential direction. The end of the movable tube 302 away from the fixed tube 301 is fixedly connected to a pulley 303. The pulley 303 is connected to the belt 203. The belt 203 drives the movable tube 302 to rotate. The movable tube 302 and the hollow tube rotate, causing fertilizer to spill out from the through holes on the movable tube 302, thereby controlling the amount of fertilizer applied and avoiding abnormal crop growth due to excessive fertilization.

[0029] The bottom of the fertilizer box 102 is tilted downward on the side away from the handle 103. A door 7 is hinged on the top of the fertilizer box 102, and a handle is fixedly connected to the door 7. The handle is pulled to rotate the door 7 around the hinge axis to pour fertilizer into the fertilizer box 102. Since the bottom of the fertilizer box 102 is tilted downward on the side away from the handle 103, the fertilizer slides toward the top of the fixed pipe 301 after being poured into the fertilizer box 102.

[0030] Working principle: When in use, the carrying platform 101 is pushed by the handle 103, so that the wheel 8 drives the wheel axle 202 to rotate, and the device is moved to the use position. Then, the handle is pulled to rotate the box door 7 around the hinge axis to pour fertilizer into the fertilizer box 102. Since the bottom of the fertilizer box 102 is tilted downward away from the side of the handle 103, the fertilizer is poured into the fertilizer box 102 and slides toward the top of the fixed tube 301. Then, the fertilizer enters the movable tube 302 through the fixed tube 301. When the carrying platform 101 is pushed to move, there is friction between the ground and the wheel 8, so that the wheel 8 drives the wheel axle 202 to rotate, and at the same time, the wheel axle 202 drives the belt 203 to move, thereby driving the movable tube 302 to rotate through the belt 203. The movable tube 302 and the hollow tube rotate, so that the fertilizer is poured out from the passage on the movable tube 302. The holes are used to sprinkle fertilizer, thereby controlling the amount of fertilizer applied and avoiding abnormal crop growth due to excessive fertilization. While fertilizing, the motor 501 drives the movable rod to rotate, so that the movable rod drives multiple loosening harrows 502 to rotate and turn over the land, so as to facilitate mixing of fertilizer and soil. Different crops have different requirements for soil depth. In order to ensure the best effect of crop planting, certain adjustments are required. The rotating turntable 6 drives the symmetrical threaded rods 402 to move synchronously through the connecting belt 403. The threaded rods 402 are threadedly matched with the lifting block 404, so that the lifting block 404 and the fixed frame 401 slide up and down, thereby adjusting the distance between the lifting block 404 and the bearing platform 101, so that the lifting block 404 drives the fixed plate 405 to move up and down, thereby adjusting the distance between the loosening harrow 502 and the bearing platform 101 and changing the loosening depth of the loosening harrow 502.
