Description

Technical Field

[0001] The invention relates to the technical field of fertilizing devices, and in particular to a liquid organic fertilizer layered deep fertilizing device and a use method thereof. Background Art

[0002] Liquid organic fertilizer application technology uses a tractor as the power source, with spray hoses arranged in parallel to form a comb-shaped spraying rack. Liquid fertilizer stored in tanks is pumped directly into the soil using a liquid pump. Directly spraying liquid fertilizer onto the soil can easily lead to fertilizer evaporation and soil compaction.

[0003] If equipped with a deep loosening device, the liquid fertilizer device and the deep loosening device are combined to achieve deep application of liquid organic fertilizer and improve the fertilization effect. The current common structure is to install a drip tube behind the coulter, and the liquid fertilizer flows into the groove behind the coulter through the drip tube.

[0004] However, for the deep loosening plow's plow blade, the plow blade is deep, and the drip tube can only drip onto the upper layer of soil, making it difficult to achieve multi-layer deep application. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a device for deep layering and applying liquid organic fertilizer and a method for using the device.

[0006] The present invention is achieved through the following technical scheme, and provides a liquid organic fertilizer layered deep application device, comprising a frame, a liquid fertilizer tank, a liquid pump and a plurality of plowshares fixedly connected to the lower end of the frame, and also comprising a fertilizer discharging mechanism fixedly connected to the back of the plowshare. The fertilizer discharging mechanism comprises a fertilizer discharging pipe and an upper slider, a middle slider and a lower slider arranged from top to bottom and attached to the inner wall of the fertilizer discharging pipe, the lower end of the fertilizer discharging pipe is closed and the upper end is connected with the liquid pump outlet, a liquid discharge pipe corresponding to the upper slider, the middle slider and the lower slider is respectively opened at the rear of the fertilizer discharging pipe, the upper slider, the middle slider and the lower slider are all opened with a through hole penetrating up and down, and a liquid discharge hole connected with the liquid discharge pipe is opened on the side of the through hole, the liquid discharge hole of the upper slider gradually increases from top to bottom, and the liquid discharge hole of the lower slider gradually decreases from top to bottom, the upper end of the fertilizer discharging pipe is axially connected to a driving screw threadedly connected with the upper slider and the middle slider, and the lower slider is connected to the middle slider.

[0007] This solution uses a coulter to achieve deep loosening of the soil, and uses a liquid pump to pump the fertilizer liquid in the liquid fertilizer tank into the fertilizer discharge pipe, and the fertilizer liquid is filled in the fertilizer discharge pipe through the through hole. The fertilizer liquid enters the discharge pipe through the discharge hole on the side of the through hole, and is discharged into the soil behind the coulter, and layered fertilization is achieved through three discharge pipes; the upper slider, middle slider and lower slider are driven to rise and fall synchronously by rotating the driving screw. When descending, the liquid discharge volume of the liquid discharge hole corresponding to the upper slider decreases, and the liquid discharge volume of the liquid discharge hole corresponding to the lower slider increases, thereby realizing the adjustment of the liquid discharge volume at different depths.

[0008] As an optimization, the fertilizer discharge pipe includes a vertical pipe section and an inclined pipe section connected to the lower end of the vertical pipe section. The upper and middle sliders are located in the vertical pipe section, and the lower slider is located in the inclined pipe section. In this solution, the vertical pipe section fits behind the coulter, and the inclined pipe section fits on the inclined surface at the lower end of the rear side of the coulter.

[0009] As an optimization, the lower slider and the middle slider are connected through a gear rack assembly, and the gear rack assembly includes an upper rack fixed to the lower end of the middle slider, a lower rack fixed to the upper end of the lower slider, and a long gear axially connected to the connection between the vertical pipe section and the oblique pipe section. The upper rack and the lower rack are both engaged with the long gear.

[0010] As an optimization, the inclined pipe section is internally connected to a lower back wheel which is pressed against the back of the lower rack, and the vertical pipe section is internally connected to an upper back wheel which is pressed against the back of the upper rack.

[0011] As an optimization, a liquid outlet cap is threadedly connected to the liquid outlet pipe, and a plurality of side liquid outlet holes are opened on the side of the liquid outlet cap.

[0012] As an optimization, the upper end of the fertilizer outlet pipe is detachably fixed with an upper plug, and the drive screw shaft is connected to the upper plug.

[0014] As an optimization, two liquid fertilizer tanks are provided and arranged left and right.

[0015] As an optimization, the fertilizer discharge pipe is connected to the back of the coulter by bolts.

[0016] A method for using a liquid organic fertilizer layered deep application device comprises the following steps: a. installing a frame on a tractor and following the tractor to achieve deep loosening of the soil by means of a plow;

[0017] b. The liquid pump pumps the liquid fertilizer in the liquid fertilizer tank into the fertilizer outlet pipe, and the liquid fertilizer fills the fertilizer outlet pipe through the through hole. The fertilizer liquid enters the liquid outlet pipe through the liquid outlet hole on the side of the through hole, and is discharged into the soil behind the coulter. Layered fertilization is achieved through the three liquid outlet pipes;

[0018] c. The upper and middle sliders are driven to rise and fall synchronously by rotating the driving screw. The middle slider drives the long gear to rotate through the upper rack, and the long gear drives the lower rack to move, thereby realizing the synchronous rise and fall of the lower and middle sliders. d. When the upper, middle and lower sliders descend, the liquid discharge of the liquid outlet corresponding to the upper slider decreases, and the liquid discharge of the liquid outlet corresponding to the lower slider increases, thereby realizing the adjustment of the liquid discharge volume at different depths.

[0027] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0028] It should be noted that in the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0029] like Figures 1 to 5As shown, a liquid organic fertilizer layered deep application device of the present invention includes a frame 3, a liquid fertilizer tank 4, a liquid pump and a plurality of plowshares 2 fixed to the lower end of the frame 3. The plowshares 2 are provided in two rows, front and back, and the plowshares 2 in the front and back rows are staggered left and right, thereby realizing side-by-side deep loosening. The plowshares 2 are mounted on the frame 3 by bolts, and the left and right positions can be adjusted to adjust the spacing during the deep loosening process.

[0030] A connecting frame 5 is fixedly connected to the front end of the frame 3. Three connection points arranged in a triangle are fixedly connected to the connecting frame 5. Each connection point is composed of two connecting plates 6, thereby realizing connection with the tractor.

[0031] The liquid fertilizer tank 4 is placed above the frame. In this embodiment, two liquid fertilizer tanks 4 are provided and arranged left and right. The liquid pump is provided between the two liquid fertilizer tanks 4 , and the inlet of the liquid pump is connected to the two liquid fertilizer tanks 4 .

[0032] It also includes a fertilizer dispensing mechanism 1 fixed to the back of the plow 2, such as Figure 5 As shown, the fertilizer discharging mechanism 1 includes a fertilizer discharging pipe and an upper slider 13, a middle slider 14 and a lower slider 15 arranged from top to bottom and attached to the inner wall of the fertilizer discharging pipe. The lower end of the fertilizer discharging pipe is closed and the upper end is connected to the liquid pump outlet. The fertilizer discharging pipe is connected to the back of the plow 2 by bolts, so that the fertilizer discharging mechanism 1 can be easily disassembled for replacement and maintenance.

[0033] like Figure 3 As shown, due to the structural limitations of the plow 2, the back of the plow 2 includes a vertical surface and an inclined surface. Therefore, in order to fit with the back of the plow 2, the fertilizer discharge pipe includes a vertical pipe section 11 and an inclined pipe section 12 connected to the lower end of the vertical pipe section. The angle between the inclined pipe section 12 and the vertical pipe section 11 is 120 degrees. The upper slider 13 and the middle slider 14 are located in the vertical pipe section 11, and the lower slider 15 is located in the inclined pipe section 12, thereby realizing the even distribution of three fertilizer outlets over the entire deep plowing height.

[0034] The upper slider 13, the middle slider 14 and the lower slider 15 are all fitted with the inner wall of the fertilizer discharge pipe. A liquid discharge pipe 21 corresponding to the upper slider 13, the middle slider 14 and the lower slider 15 is opened at the rear of the fertilizer discharge pipe. The liquid discharge pipe 21 is connected to the side of the upper slider 13, the middle slider 14 and the lower slider 15. The upper slider 13, the middle slider 14 and the lower slider 15 are all opened with a through hole running through from top to bottom, and a liquid outlet hole connected to the liquid outlet pipe 21 is opened on the side of the through hole, so that after the liquid pump pumps the liquid fertilizer into the fertilizer discharge pipe, the liquid fertilizer fills the entire fertilizer discharge pipe through the connection of the through hole, and at the same time enters the liquid discharge pipe 21 through the side liquid outlet hole, and finally is discharged through the liquid discharge pipe 21.

[0035] The liquid outlet of the upper slider 13 gradually increases from top to bottom. Figure 5As shown, the liquid outlet hole of the upper slider 13 is triangular, so that when the upper slider 13 moves downward, the liquid outlet volume of the uppermost liquid outlet pipe 21 will decrease, and when the upper slider 13 moves upward, the liquid outlet volume of the uppermost liquid outlet pipe 21 will increase.

[0036] The liquid outlet hole of the lower slider 15 gradually decreases from top to bottom. The liquid outlet hole of the lower slider 15 is an inverted triangle, so that when the lower slider 15 moves downward, the liquid outlet amount of the lowermost liquid outlet pipe 21 will increase, and when the lower slider 15 moves upward, the liquid outlet amount of the lowermost liquid outlet pipe 21 will decrease.

[0037] The liquid outlet holes of the middle slider 14 are uniformly sized, so the liquid output of the middle slider is basically constant. Therefore, when the upper slider 13, the middle slider 14 and the lower slider 15 descend synchronously, the amount of fertilizer applied will increase as the depth increases. When the upper slider 13, the middle slider 14 and the lower slider 15 ascend synchronously, the amount of fertilizer applied will decrease as the depth increases, thereby adapting to the requirements of different crops for fertilizer application at different depths.

[0038] To achieve synchronous lifting of the upper, middle, and lower sliders 13, 14, and 15, the upper end of the fertilizer discharge pipe is axially connected to a drive screw 16 threadedly connected to the upper and middle sliders 13, 14. Rotation of the drive screw 16 can drive the upper and middle sliders 13, 14 to rise and fall synchronously. In this embodiment, the upper end of the fertilizer discharge pipe is detachably fixedly connected to an upper plug 17. The drive screw 16 is axially connected to the upper plug 17, making it easy to disassemble the upper end for maintenance. The upper plug 17 is inserted into the upper end of the fertilizer discharge pipe and secured to the side with a fastening screw. A liquid inlet pipe 19 is connected to the upper plug 17, thereby connecting it to the outlet of the liquid pump. A lower plug 23 is installed at the lower end of the fertilizer discharge pipe to achieve blockage at the lower end.

[0039] The upper end of the driving screw 16 passes through the upper plug 17 , and a hand wheel 20 is fixedly connected to the upper end of the driving screw 16 to facilitate manual rotation of the driving screw 16 .

[0040] To achieve the up and down movement of the lower slider 15, the lower slider 15 is connected to the middle slider 14. In this embodiment, the lower slider 15 and the middle slider 14 are connected via a rack and pinion assembly. The rack and pinion assembly includes an upper rack 26 fixed to the lower end of the middle slider 14, a lower rack 24 fixed to the upper end of the lower slider 15, and a long gear 25 axially connected to the connection between the vertical tube section 11 and the oblique tube section 12. The length of the upper rack 26 is parallel to the movement direction of the middle slider 14, and the length of the lower rack 24 is parallel to the movement direction of the lower slider 15. The upper rack 26 and the lower rack 24 are staggered.

[0041] The upper rack 26 and the lower rack 24 are both engaged with the long gear 25. Thus, the movement of the lower rack 24 is driven by the movement of the upper rack 26.

[0042] The inner axis of the inclined pipe section 12 is connected to a lower back wheel 27 that presses against the back of the lower rack 24 to prevent the lower rack 24 from deforming and improve the meshing effect. The inner axis of the vertical pipe section 11 is connected to an upper back wheel 28 that presses against the back of the upper rack 26 to prevent the upper rack 26 from deforming and improve the meshing effect.

[0043] The liquid outlet pipe 21 is threadedly connected to a liquid outlet cap 22, which has multiple side liquid outlet holes on its side. The liquid outlet cap 22 comprises a circular tube and an end plate fixed to one end of the circular tube. The circular tube is inserted into the liquid outlet pipe 21 and threadedly connected. The side liquid outlet holes are arranged on the circular tube and are evenly distributed around the circumference. The purpose of providing the liquid outlet cap 22 is to disperse the large diameter of the liquid outlet pipe 21 into multiple smaller diameter side liquid outlet holes, preventing soil from entering the liquid outlet pipe. At the same time, by rotating the liquid outlet cap 22, the side liquid outlet holes are rotated into the interior of the liquid outlet pipe 21, directly closing the liquid outlet pipe 21, thereby achieving the individual closure of each liquid outlet pipe 21.

[0044] A method for using a liquid organic fertilizer layered deep application device comprises the following steps: a. installing a frame 3 on a tractor and moving it along with the tractor, achieving deep loosening of the soil through a coulter 2; b. pumping liquid fertilizer from a liquid fertilizer tank 4 into a fertilizer outlet pipe with a liquid pump, and filling the fertilizer outlet pipe with the liquid fertilizer through a through hole, and then the liquid fertilizer enters the liquid outlet pipe 21 through a liquid outlet hole on the side of the through hole, and is then discharged into the soil behind the coulter 2, achieving layered fertilization through the three liquid outlet pipes 21;

[0045] c. The upper slider 13 and the middle slider 14 are driven to rise and fall synchronously by rotating the driving screw 16. The middle slider 14 drives the long gear 25 to rotate through the upper rack 26, and the long gear 25 drives the lower rack 24 to move, thereby achieving synchronous lifting of the lower slider 15 and the middle slider 14.

[0046] d. When the upper slider 13, the middle slider 14 and the lower slider 15 descend, the liquid discharge from the liquid outlet corresponding to the upper slider 13 decreases, and the liquid discharge from the liquid outlet corresponding to the lower slider 15 increases, thereby achieving adjustment of the liquid discharge at different depths.
