Description

Technical Field

[0001] This utility model relates to the field of fertilization technology, specifically to a root-injection liquid fertilizer application device. Background Technology

[0002] Liquid fertilizers offer advantages such as easy absorption and convenient mixing, and are widely used in the cultivation of cash crops in southern, western, and southwestern my country. Application methods include drip irrigation, spraying, and infusion. However, drip irrigation has a high initial investment cost; spraying is prone to evaporation; and infusion is only suitable for larger, mature seedlings. Therefore, a device that saves on liquid fertilizer and is adaptable to different plant types is needed when applying liquid fertilizers.

[0003] For example, the patent with publication number CN208029438U discloses a liquid fertilizer gun, which includes a gun body, a handle, a foot pedal, and a gun head. The gun body and handle are hollow. The handle is located at the top of the gun body and has a switch. Above the switch is a resistance baffle with a pressure gauge. The foot pedal is located in the lower middle part of the gun body. The gun head is connected to the bottom of the gun body and has several discharge ports. This device has two layers of resistance baffles. The flow rate and pressure inside the gun body are controlled by the overlap of the two layers of baffles. The pressure is closely monitored to effectively control the fertilizer throughput and prevent the liquid from leaking from the top of the gun body and spraying onto the operator, thereby reducing the fertilizer utilization rate. It is also simple to operate.

[0004] This device solves the problems of nozzle clogging and difficulty in cleaning by using a detachable nozzle, but this method also indirectly increases the cost of use. Therefore, we propose a root injection liquid fertilizer application device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a root-injection liquid fertilizer application device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a root-injection type liquid fertilizer application device, comprising a gun body, one end of the gun body being rotatably connected to an adjustment shaft via a sealed bearing, one end of the adjustment shaft being fixedly connected to an adjustment knob, the adjustment knob being movably disposed outside the gun body, the other end of the adjustment shaft being fixedly connected to the middle of one end face of a connecting plate, and two sides of the other end face of the connecting plate being fixedly connected to cores, the cores being rotatably sleeved on the bottom end of the gun body;

[0007] The bottom of the gun body is provided with a plurality of evenly distributed discharge holes 1, and the middle part of the core body is provided with a plurality of evenly distributed discharge holes 2, and the discharge holes 2 and discharge holes 1 are provided in a one-to-one correspondence;

[0008] Handles are fixedly connected to both ends of the top of the gun body. An operating handle is movably provided at the bottom of one of the handles. A support seat is hinged to one side of the operating handle. The bottom end of the support seat is fixedly connected to the outer wall of the pressing valve. One end of the pressing valve is fixedly connected to the gun body. The valve stem end of the pressing valve is in sliding contact with one end of the operating handle.

[0009] Preferably, the diameters of the second discharge hole and the first discharge hole are equal, and the distance between two adjacent second discharge holes is greater than the diameter of the second discharge hole.

[0010] Preferably, the core is composed of a cone and a cylinder, and the two discharge holes are provided through the cylinder.

[0011] Preferably, the end of the press valve away from the gun body is fixedly provided with a threaded joint.

[0012] Preferably, the end face of the adjustment knob away from the gun body is provided with an indicator needle.

[0013] Preferably, one end face of the gun body is provided with an on / off mark, and an auxiliary pedal is fixedly connected to one side outer wall of the gun body, with the length direction of the auxiliary pedal being perpendicular to the length direction of the gun body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The adjustment knob drives the adjustment shaft to rotate, and the adjustment shaft, together with the connecting plate, drives the core to rotate. When the core rotates, it causes the second discharge hole to be misaligned with the first discharge hole of the gun body. That is, the core blocks the first discharge hole of the gun body, thereby preventing soil from entering the gun body when the gun body is inserted into the soil.

[0016] 2. During fertilization, liquid fertilizer is delivered to the gun body through the infusion pump. The adjustment knob is rotated in the opposite direction, which drives the core body to rotate in the opposite direction. The second discharge hole of the core body coincides with the first discharge hole of the gun body. The pressure of the liquid flushes out the soil embedded in the first discharge hole, thus realizing the fertilization operation of liquid fertilizer.

[0017] 3. When the core is used to seal the discharge port of the gun body, the space inside the discharge port is extremely small. Even if there is soil inside, it is easy to clean the discharge port. At the same time, it also prevents soil from entering the gun body when it is pulled out. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a root injection liquid fertilizer application device, including a gun body 1. One end of the gun body 1 is rotatably connected to an adjustment shaft 8 through a sealed bearing. One end of the adjustment shaft 8 is fixedly connected to an adjustment knob 7, which is movably located outside the gun body 1. The other end of the adjustment shaft 8 is fixedly connected to the middle of one end face of a connecting plate 9. The other end face of the connecting plate 9 is fixedly connected to two sides of a core 10, which is rotatably sleeved inside the bottom of the gun body 1.

[0025] The bottom of the gun body 1 is provided with multiple evenly distributed discharge holes 101, and the middle part of the core body 10 is provided with multiple evenly distributed discharge holes 11. The discharge holes 11 and discharge holes 101 are provided in a one-to-one correspondence.

[0026] Handles 3 are fixedly connected to the top two ends of the gun body 1. An operating handle 5 is movably provided at the bottom of one of the handles 3. A support seat 6 is hinged to one side of the operating handle 5. The bottom end of the support seat 6 is fixedly connected to the outer wall of the pressing valve 4. One end of the pressing valve 4 is fixedly connected to the gun body 1. The valve stem end of the pressing valve 4 slides in contact with one end of the operating handle 5. Example

[0027] Reference Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the diameters of the discharge hole 2 11 and the discharge hole 101 are equal. The distance between two adjacent discharge holes 2 11 is greater than the diameter of the discharge hole 2 11. That is, when the discharge hole 2 11 of the core 10 is misaligned with the discharge hole 101 of the gun body, the core 10 can block the discharge hole 101 of the gun body 1.

[0028] Specifically, the core 10 is composed of a cone and a cylinder, with the discharge hole 11 penetrating through the cylinder. A sealing ring is fixedly connected to the inner wall of the gun body 1, and the sealing ring slides in contact with the top wall of the core 10 to seal between the core 10 and the inner wall of the gun body 1, thereby improving the sealing performance at the connection between the core 10 and the gun body 1.

[0029] Specifically, a threaded connector 41 is fixedly provided at the end of the press valve 4 away from the gun body 1. The threaded connector 41 is connected to the pump body and the liquid fertilizer storage tank with a hose for conveying liquid fertilizer into the gun body 1. The press valve 4 can be a valve body without a delayed closing function for immediate on / off control of the liquid fertilizer.

[0030] Specifically, an indicator needle 71 is provided on the end face of the adjustment knob 7 away from the gun body 1.

[0031] Specifically, one end face of the gun body 1 is provided with an on / off indicator 102. The on / off indicator 102 cooperates with the indicator needle 71 to facilitate the operator to check the positional relationship between the discharge hole 2 11 of the core 10 and the discharge hole 101 of the gun body, and to facilitate the operation of opening and closing the discharge hole 2 11. An auxiliary pedal 2 is fixedly connected to one side of the outer wall of the gun body 1. The length direction of the auxiliary pedal 2 is set perpendicular to the length direction of the gun body 1. The auxiliary pedal 2 is set to facilitate the user to apply downward pressure to the gun body 1 by stepping on it.

[0032] The working principle and process are as follows: The threaded connector 41 connects the pump body and the liquid fertilizer storage tank with the hose, and is used to deliver liquid fertilizer into the gun body 1. By holding the handle 3, the gun body 1 is inserted into the position where fertilization is needed. The pedal 2 allows the user to apply downward pressure to the gun body 1 by foot, which improves the smoothness of the insertion of the gun body 1 into the soil. Before the gun body 1 is inserted into the soil, the discharge hole 11 of the core 10 is misaligned with the discharge hole 101 of the gun body, that is, the core 10 blocks the discharge hole 101 of the gun body 1, thereby preventing the gun body from being inserted into the soil. When the soil enters the gun body 1, the gun body 1 stops after being inserted into the fertilization position. The operating handle 5 is manually operated. The operating handle 5 presses down the control valve rod of the press valve 4 through the lever principle, so that the press valve 4 is open. The liquid fertilizer is delivered into the gun body 1 through the press valve 4. At the same time as operating the operating handle 5, the adjustment knob 7 is rotated in the opposite direction, which drives the core 10 to rotate in the opposite direction. The second discharge hole 11 of the core 10 coincides with the discharge hole 101 of the gun body. The pressure of the liquid flushes out the soil embedded in the discharge hole 11, realizing the fertilization operation of liquid fertilizer.

[0033] It should be noted that the specific model and specifications of the push valve need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
