Description

Technical Field

[0001] The utility model relates to the technical field of plant root pesticide applicators, in particular to a matrix-cultivated plant root pesticide applicator. Background Art

[0002] At present, the traditional fertilization method for crops is relatively primitive and extensive, usually spraying directly to complete the fertilization, resulting in poor plant nutrient absorption. Especially in the process of substrate cultivation, because it adopts soilless cultivation, plants grow by absorbing nutrient solution and oxygen. Therefore, the traditional fertilization method is not suitable for substrate cultivation. In order to effectively fertilize the roots of plants, the existing operation method is usually to shovel and separate the substrate, and then water it separately.

[0003] An existing substrate-cultivated plant root applicator (authorization announcement number CN206620649U) has the following defects: the above-mentioned device injects the nutrient solution or medicine to be applied into the medicine adding port through the medicine bottle, and the internal cavity of the medicine bottle is connected with the medicine application cavity, so that the nutrient solution or medicine flows into the medicine application cavity to the nutrient trough, and then flows into the substrate through the nutrient trough to complete the application of medicine to the plant roots. However, during the application process, the medicine flows from the medicine application cavity and the nutrient trough into the plant cavity in the substrate. During the flow process, it is difficult for the staff to control the amount of the medicine flowing in, which is prone to over- or under-application, resulting in poor effect of applying medicine to the plant roots. For this reason, we propose the utility model. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please see attached Figure 1 -Attached Figure 4 A root applicator for substrate-cultivated plants comprises a medicine cartridge 1, wherein a medicine application structure is arranged inside the medicine cartridge 1, and the medicine application structure comprises an outflow groove 2 provided on the inner circular wall surface of the medicine cartridge 1, a guide column 201 is slidably inserted inside the outflow groove 2, a discharge groove 202 is provided on the outer circular wall surface of the guide column 201, a pressing column 203 is slidably inserted inside the medicine cartridge 1, a piston 204 is fixed to the bottom end of the pressing column 203, a connecting rod 205 is fixed to the outer circular wall surface of the pressing column 203, one end of the connecting rod 205 is fixed to the top end of the guide column 201, and the piston 204 is made of rubber.

[0022] In the embodiment, an insertion head 206 is fixed at the bottom end of the cartridge 1, and the insertion head 206 is conical. A separation shovel 207 is fixed at the bottom end of the insertion head 206. Through the setting of the drug application structure, the staff holds the cartridge 1, inserts the insertion head 206 into the root position of the plant in the matrix, and slightly shakes the cartridge 1 to make the separation shovel 207 separate the matrix at the root position of the plant to form a drug application gap, and then presses the pressing column 203 to make the guide column 201 extend from the bottom end of the cartridge 1. At this time, the drug solution flows out of the cartridge 1 into the discharge groove 202, and the drug in the discharge groove 202 is discharged. The liquid will not flow out of the discharge groove 202 due to its surface tension. The pressing column 203 is continuously pressed, and the piston 204 moves downward in the cartridge 1 to pressurize the liquid medicine in the cartridge 1, so that the liquid medicine is sprayed out from the discharge groove 202 to the outer wall surface of the insertion head 206. Since the insertion head 206 is conical, the liquid medicine flows from the insertion head 206 to the root of the plant under the guidance of the insertion head 206. The staff can control the dosage by controlling the pressing depth of the pressing column 203, thereby realizing accurate application of medicine to the plant roots and ensuring the effect of application of medicine to the plant roots.

[0023] In the embodiment, the outer circumferential wall surface of the pressing column 203 is wrapped with a spring 3, and the inner circumferential wall surface of the cartridge 1 is fixed with a limiting ring 301, and the top of the limiting ring 301 is fixed to the bottom end of the spring 3. When the staff presses the pressing column 203 to apply the medicine, the spring 3 is compressed. After pressing and applying the medicine, the spring 3 is reset, so that the pressing column 203 rises and returns to the position before applying the medicine, which is convenient for the staff to apply the medicine again.

[0024] In the embodiment, a first sealing ring 4 is fixed to the inner circular wall surface of the cartridge 1, and the first sealing ring 4 is located below the limiting ring 301. The inner circular wall surface of the first sealing ring 4 fits with the outer circular wall surface of the pressing column 203. A second sealing ring 401 is fixed inside the outflow groove 2, and the inner circular wall surface of the second sealing ring 401 fits with the outer circular wall surface of the guide column 201. Both the first sealing ring 4 and the second sealing ring 401 are prior arts. The first sealing ring 4 can prevent the medicine liquid from flowing out from between the cartridge 1 and the pressing column 203. The second sealing ring 401 can prevent the medicine liquid from flowing out from between the guide column 201 and the outflow groove 2 when the guide column 201 does not extend out of the cartridge 1, thereby improving the sealing performance of the device.

[0025] In the embodiment, an observation window 5 is provided on the outer circumferential wall surface of the cartridge 1, and the observation window 5 is connected to the interior of the cartridge 1. Glass is fixed inside the observation window 5. A scale is engraved on the outer circumferential wall surface of the cartridge 1. When applying the medicine, the staff can observe the remaining medicine liquid in the cartridge 1 through the observation window 5 and accurately control the application amount according to the scale.

[0026] In the embodiment, a plurality of holding grooves 6 are provided on the outer circumferential wall surface of the cartridge 1, a dosing hole 601 is provided on the outer circumferential wall surface of the cartridge 1, and a cap is threadedly connected to the outer circumferential wall surface of the dosing hole 601. When administering the medicine, the staff can inject the medicine liquid into the cartridge 1 through the dosing hole 601, and then hold the cartridge 1 through the holding grooves 6.

[0027] Working principle: During use, the staff first injects the medicine liquid into the cartridge 1 through the dosing hole 601, and then holds the cartridge 1 through the holding groove 6. After that, the staff holds the cartridge 1, inserts the insertion head 206 into the root position of the plant in the matrix, and slightly shakes the cartridge 1 to make the separation shovel 207 separate the matrix at the root position of the plant to create a medicine application gap, and then presses the pressing column 203 to make the guide column 201 extend from the bottom end of the cartridge 1. At this time, the medicine liquid flows out of the cartridge 1 into the discharge groove 202, and the medicine liquid in the discharge groove 202 will not flow out of the discharge groove 202 due to its surface tension. Continue to press the pressing column 203, the piston 204 moves downward in the cartridge 1, and the medicine liquid in the cartridge 1 is pressurized, so that the medicine liquid is sprayed from the discharge groove 202 to the outer wall surface of the insertion head 206, and then the pressure column 203 is pressed. The insertion head 206 is conical. Under the guidance of the insertion head 206, the medicine liquid flows from the insertion head 206 to the root of the plant. The staff can control the dosage by controlling the pressing depth of the pressing column 203. When the staff presses the pressing column 203 to apply the medicine, the spring 3 is compressed. After pressing and applying the medicine, the spring 3 is reset, so that the pressing column 203 rises and resets to the position before applying the medicine, which is convenient for the staff to apply the medicine again. The first sealing ring 4 can prevent the medicine liquid from flowing out from between the cartridge 1 and the pressing column 203. The second sealing ring 401 can prevent the medicine liquid from flowing out from between the guide column 201 and the outflow groove 2 when the guide column 201 does not extend out of the cartridge 1. When applying the medicine, the staff can observe the remaining medicine liquid in the cartridge 1 through the observation window 5, and accurately control the amount of medicine applied according to the scale.
