Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer application tools, in particular to a portable fertilizer applicator. Background Art

[0002] After the crop seedlings are transplanted to the field, they need to be fertilized. The fertilizer is close to the roots of the crops to promote the growth of the crops. The traditional way of fertilizing is for two people to cooperate with each other. One person holds a hoe and digs a hole near the roots of the crops, and the other holds a basin of fertilizer, takes out an appropriate amount of fertilizer from the basin and throws it into the hole. When the hoe digs a hole, the excavated soil is covered on the fertilizer, and the person's feet step on the soil to flatten it. Repeat the above actions to complete the purpose of fertilizing the crops.

[0003] With respect to the above-mentioned related technologies, the inventors found that traditional fertilization requires two people to work together, which increases the number of fertilization workers. In addition, during the fertilization process, due to the misoperation of the operators, the hoe is prone to injure people, reducing the safety of labor. Therefore, it is necessary to design a fertilization tool suitable for single-person operation. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a convenient fertilizer applicator which is suitable for single-person fertilization operation, reduces the number of fertilization operators, and improves the safety of fertilization operation.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a portable fertilizer applicator, comprising: a hollow round rod body and a triangular shovel head connected to the lower end thereof, the front of the triangular shovel head is concavely provided with a guide groove, the inner cavity of the hollow round rod body is provided with a circular valve plate, the outer circumferential surface of the circular valve plate is symmetrically connected with two supporting shafts, the outer ends of the supporting shafts respectively pass through the circular wall of the hollow round rod body and are rotatably connected thereto, the outer end of one of the supporting shafts is connected with a torsion spring reset assembly, and the outer end of the other supporting shaft is connected with a grip-type handle driving assembly for driving the circular valve plate to flip, the inner wall of the hollow round rod body is connected with a limiting block, and the circular valve plate is in abutment with the limiting block, which is suitable for preventing the fertilizer in the hollow round rod body from flowing downward;

[0006] The outer circumferential surface of the hollow round rod body is connected with a transverse fixing rod, and the transverse fixing rod is connected with a material storage box assembly, and the inner cavity of the material storage box assembly is communicated with the inner cavity of the hollow round rod body.

[0007] By adopting the above technical scheme, when in use, an appropriate amount of fertilizer is loaded into the inner cavity of the storage box assembly, and the fertilizer in the storage box assembly flows into the inner hole of the hollow round rod body. The circular valve plate blocks the fertilizer from continuing to flow downward, and the hollow round rod body is operated to be lifted to a certain height and then quickly moved downward, so that the triangular shovel head is inserted into the soil next to the crops, and then the hollow round rod body is operated to deviate backward by a certain angle, so that a certain fertilizer storage gap is left in front of the triangular shovel head, and the grip handle driving assembly is operated to drive the circular valve plate to flip by a certain angle, and the hollow round rod body is moved downward by a certain angle. An appropriate amount of fertilizer flows downward into the guide groove on the front side of the triangular shovel head. Under the action of the torsion spring reset assembly, the circular valve plate flips reversely at a certain angle and contacts with the limit block, so that the circular valve plate prevents the fertilizer from continuing to flow downward. The fertilizer in the guide groove flows into the fertilizer storage gap, and moves the hollow round rod body upward to a certain height, so that the triangular shovel head leaves the soil, and then the soil is slightly moved by the foot to cover the fertilizer and then flattened, thereby achieving the purpose of single-person fertilization, reducing the number of fertilization workers and improving the safety of fertilization operations.

[0008] In a preferred example, the utility model can be further configured as follows: the torsion spring reset assembly includes an end plate and a torsion spring sleeved on the support shaft, the end plate is connected to the outer end of the support shaft, one end of the torsion spring passes through the end plate, and the other end passes through the circular wall of the hollow circular rod body.

[0009] By adopting the above technical solution, the grip handle driving assembly drives the circular valve plate to flip a certain angle, driving the torsion spring to twist. After the grip handle driving assembly is released, under the reverse action of the torsion spring, the circular valve plate rotates in the opposite direction to prevent the fertilizer from flowing downward.

[0010] In a preferred example, the utility model can be further configured as follows: the grip handle drive assembly includes an articulated seat, a handle and a tension spring reset member, the articulated seat is connected to the outer circle of the hollow circular rod body, the handle and the articulated seat are connected by a pin shaft, one end of the tension spring reset member is connected to the handle, and the other end is connected to the outer circle of the hollow circular rod body, and also includes a flip rod, one end of the flip rod is connected to the outer circle of the support shaft, and a pull rope is connected between the other end of the flip rod and the handle, and a circular guide sleeve is sleeved on the outer side of the pull rope, and the circular guide sleeve is connected to the outer circle of the hollow circular rod body.

[0011] By adopting the above technical solution, the handle is held tightly with the hand, and the handle swings to drive the pull rope to move. The pull rope drives the support shaft to rotate through the flip rod, and the support shaft drives the circular valve plate to flip, so that the fertilizer in the hollow round rod body flows downward into the guide groove. After an appropriate amount of fertilizer flows into the guide groove, the handle is released and under the action of the tension spring reset member, the handle returns to its initial position.

[0012] In a preferred example, the utility model can be further configured as follows: the tension spring reset member includes a tension spring and a semicircular ring connected to the outer circle of the hollow round rod, one end of the tension spring is connected to the semicircular ring, and the other end is connected to the handle.

[0013] By adopting the above technical solution, the handle is restored to its initial position under the tension of the tension spring.

[0014] In a preferred example, the present invention can be further configured as follows: a horizontal handle is connected to the upper end of the hollow round rod.

[0015] By adopting the technical solution, the horizontal handle makes it easier for a fertilizer applicator to operate the fertilizer applicator, thereby improving the use effect.

[0016] In a preferred example, the utility model can be further configured as follows: the material storage box assembly includes a material storage box and a material delivery pipe connected to the lower end of the material storage box, the end of the material delivery pipe away from the material storage box is connected to the outer circle of the hollow round rod body, and the material storage box is connected to the transverse fixing rod by bolts.

[0017] By adopting the above technical solution, a proper amount of fertilizer is placed in the storage box, and the fertilizer enters the inner hole of the hollow round rod through the feeding pipe, so as to facilitate intermittent fertilization to the roots of crops.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] The triangular shovel head is inserted into the soil next to the crops, and the hollow round rod is operated to offset backward at a certain angle, so that a certain fertilizer storage gap is left in front of the triangular shovel head. The grip handle driving assembly is operated to drive the circular valve plate to flip at a certain angle, and an appropriate amount of fertilizer in the hollow round rod flows downward into the guide groove in front of the triangular shovel head. The fertilizer in the guide groove flows into the fertilizer storage gap. After the triangular shovel head leaves the soil, the soil is slightly moved by the foot to cover the fertilizer and then flattened, thereby achieving the purpose of single-person fertilization, reducing the number of fertilization workers and improving the safety of fertilization operations.
