Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of soybean cultivation and relates to a device for topdressing soybeans with liquid biological fertilizer in soil at the roots of the soybeans. Background Art
[0002] During soybean cultivation, applying liquid biofertilizer to the soybean roots after diluting it with water is an important measure to promote soybean growth and increase soybean yield. The existing topdressing method involves diluting liquid biofertilizer with water and then pouring or flushing it onto the soil surface at the soybean roots, allowing the liquid biofertilizer to seep into the soil at the soybean roots. However, during this topdressing process, it was found that the diluted liquid biofertilizer easily flows outward from the soil surface, reducing the amount of liquid biofertilizer that seeps into the soil within the effective range of the soybean roots. This results in a waste of liquid biofertilizer, causing the topdressing dosage required for soybean growth to fall short of the designed dosage, thus affecting soybean growth and yield.

The bottom end of the hollow rod 1 is in a pointed cone shape, which makes it easier to insert the bottom end of the hollow rod 1 into the soil at the root of the soybean. A plurality of liquid outlet holes 12 are provided on the side wall of the pointed cone section at the bottom end of the hollow rod 1. The liquid biofertilizer pumped into the injection channel of the hollow rod 1 can be injected into the soil through the outlet at the bottom end of the hollow rod 1 and each liquid outlet hole 12, thereby increasing the radiation range of the liquid biofertilizer in the soil at the root of the soybean.
[0025] A handle 10 is fixed to the top of the hollow rod 1, so that the fertilizer operator can hold the handle 10 by hand to control the hollow rod 1, so as to insert the bottom end of the hollow rod 1 into the soil at the root of soybeans or pull the hollow rod 1 out of the soil.
[0026] like Figure 1 As shown, the micro water pump 2 and the battery 4 are both installed in the suitcase 3. The water inlet of the micro water pump 2 is connected to the liquid supply source of the liquid biological fertilizer through the water inlet hose 8. For example, the water inlet hose 8 is externally connected to a backpack water tank, and the backpack water tank is filled with liquid biological fertilizer diluted with water. The water outlet of the micro water pump 2 is connected to the top of the hollow rod 1 through the water outlet hose 9. The micro water pump 2 is used to pump the liquid biological fertilizer into the injection channel of the hollow rod 1 so that the liquid biological fertilizer is directly applied to the soil from the bottom end of the hollow rod 1, which can reduce the waste of liquid biological fertilizer and improve the effect of soybean topdressing.
[0027] The battery 4 is used to power the micro water pump 2 to meet the power supply needs of the micro water pump 2 when the topdressing device is used outdoors; specifically, the battery 4 can be selected from the XY-L1240 type lithium battery, or a conventional selection can be made from other existing product models of lithium batteries and lead-acid batteries.
[0028] like Figure 1 and Figure 3 As shown, the delay relay module 7 is embedded in the top of the suitcase 3 and is used to control the start and stop of the micro water pump 2;
[0029] A handle 5 is installed on the top of the suitcase 3 for the fertilizer applicator to carry the suitcase 3. A button switch 6 for triggering the delay relay module 7 is installed on the handle 5. The button switch 6 is installed on the handle 5 so that the fertilizer applicator can control the button switch 6 with his fingers when holding the suitcase 3.
[0030] The button switch 6 and the time delay relay module 7 are both electrically connected to the battery 4, the time delay relay module 7 is electrically connected to the button switch 6, the micro water pump 2 is electrically connected to the time delay relay module 7, a threading hole is provided on the suitcase 3, and a power taking module for charging the battery 4 is installed on the suitcase 3; after pressing the button switch 6, the signal of the time delay relay module 7 is triggered, the time delay relay module 7 is turned on for the OP time (on time) and then disconnected, and the micro water pump 2 starts and stops after the OP time;
[0031] like Figure 3 As shown, the time delay relay module 7 includes a display screen 7.1 for displaying time and an increase button 7.2 and a decrease button 7.3 for setting time. By adjusting the OP time of the time delay relay module 7, the operating time of the micro water pump 2 can be adjusted, thereby controlling the micro water pump 2 to pump the dosage of liquid biological fertilizer into the injection channel of the hollow rod 1;
[0032] In this embodiment, the time delay relay module 7 may be of type XY-WM01 or other conventionally selected existing product models; the micro water pump 2 may be of type AD20P-DC12V or other conventionally selected existing product models.
[0033] Preferably, in this embodiment, Figure 1 and Figure 2 As shown, the bottom outer wall of the hollow plug 1 is provided with a positioning ring 11 which can be adjusted in installation height along the axial direction of the hollow plug 1. The positioning ring 11 is used to locate the depth of the hollow plug 1 inserted into the soil; the distance from the positioning ring 11 to the bottom end surface of the hollow plug 1 is adjustable, and the height of the positioning ring 11 can be adjusted according to the depth requirement of the bottom end of the hollow plug 1 inserted into the soil; when the bottom end of the hollow plug 1 is inserted into the soil of the soybean root, when the positioning ring 11 touches the ground, it indicates that the bottom end of the hollow plug 1 is inserted into place, and positioning by using the positioning ring 11 can avoid insufficient insertion depth or excessive insertion;
[0034] Specifically, the positioning ring 11 is a T-shaped sleeve structure, the inner wall of which is provided with an internal thread, and the outer wall of the hollow insertion rod 1 is provided with an external thread. The positioning ring 11 is threadedly connected to the outer wall of the hollow insertion rod 1, and its height can be adjusted by twisting the positioning ring 11; in addition, the positioning ring 11 can also be composed of two arc-shaped splints, and the two arc-shaped splints are buckled on the hollow insertion rod 1 to form a T-shaped sleeve structure. The two arc-shaped splints are detachably connected by bolts, which can also facilitate the adjustment of its height on the hollow insertion rod 1.
[0035] The method of using the topdressing device is as follows:
[0036] During soybean cultivation, the topdressing device is used to topdress the diluted liquid biological fertilizer into the soil at the roots of soybeans. The fertilizer carries a water tank filled with the diluted liquid biological fertilizer on his back, holds the suitcase 3 in one hand, and controls the hollow rod 1 with the other hand by holding the handle 10. The water inlet hose 8 connects the water inlet of the micro water pump 2 with the water tank, and the water outlet hose 9 connects the water outlet of the micro water pump 2 with the top of the hollow rod 1. The fertilizer sets the single operation time of the micro water pump 2 by using the increase button 7.2 and the decrease button 7.3 on the delay relay module 7, for example, setting the single fertilization time to three seconds.
[0037] The fertilizing worker controls the hollow plug rod 1 to insert the bottom end of the hollow plug rod 1 into the soil at the root of the soybean. The thumb of the hand carrying the suitcase 3 presses the button switch 6, and the signal of the delay relay module 7 is triggered. The delay relay module 7 is turned on for three seconds and then disconnected. The micro water pump 2 starts and then stops after three seconds. When the micro water pump 2 starts, the liquid biological fertilizer in the water tank is pumped into the hollow plug rod 1, and is injected into the soil from the bottom outlet of the hollow plug rod 1 and each liquid outlet 12, so that the liquid biological fertilizer is directly applied to the soil; after the micro water pump 2 stops, the hollow plug rod 1 is pulled out of the soil and fertilized at the next soybean plant; the operating time of the micro water pump 2 can be set by the delay relay module 7, so as to control the fertilizer dosage of a single soybean plant, and quantitative fertilization of the liquid biological fertilizer can be carried out, which can facilitate uniform fertilization of the soybeans;
[0038] The topdressing device can be used to apply liquid biological fertilizer directly to the soil at the roots of soybeans. Compared with the fertilization method of applying liquid biological fertilizer on the soil surface, the topdressing device can reduce the waste of liquid biological fertilizer, help the topdressing required for soybean growth reach the designed dosage, and improve the topdressing effect of soybeans.
