Description

Technical Field

[0001] The utility model belongs to the technical field of sowing, and in particular relates to a sowing device for greenhouse seedling raising and transplanting experiments. Background Art

[0002] When conducting greenhouse seedling raising and transplanting experiments, the seeds need to be sprinkled on the substrate or transplanted into the soil. Transplanting is to move the seedlings that have grown to a certain size on the seedling tray into small pots one by one.

[0003] At present, the main method for raising seedlings and transplanting is to place the seeds in the hands and sprinkle them at once, and to plant the seedlings in the soil with tweezers and hands during transplanting. However, the location of the seeds cannot be determined during sowing, and the soil is sometimes not moist enough during transplanting. After planting, the soil needs to be watered according to the soil conditions, which is time-consuming and laborious.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0005] The utility model aims to solve the problems of the current sowing device that the scattering position of seeds cannot be determined during sowing, and the soil moisture is sometimes insufficient during transplanting, and the soil needs to be watered according to the soil conditions after planting, which is time-consuming and laborious.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A sowing device for greenhouse seedling raising and transplanting experiments comprises a first iron sheet and a second iron sheet, wherein the lower parts of the first iron sheet and the second iron sheet are both sharp-shaped, and the upper parts are both semi-cylindrical, and a first handle and a second handle are fixedly installed on the upper parts of the first iron sheet and the second iron sheet respectively, and the first iron sheet is rotatably connected to the upper parts of the second iron sheet, a seed conveying tube is fixedly installed on the inner side of the second iron sheet, a baffle is rotatably installed on the lower end of the seed conveying tube, a torsion spring is provided at the junction of the baffle and the seed conveying tube, and an infusion tube is fixedly installed on the inner side of the first iron sheet.

[0008] It is further defined that a liquid storage barrel is fixedly installed on the inner side of the first iron sheet, the upper end of the liquid infusion tube is fixedly connected to the lower output port of the liquid storage barrel, a partition is fixedly installed at the lower end of the liquid infusion tube, micropores are opened on the partition, a water inlet is provided at the upper end of the liquid storage barrel, a movable plug is provided at the water inlet, and a squeezing mechanism that can squeeze the liquid in the liquid storage barrel outward is provided on the liquid storage barrel. With such a structural design, when the movable plug blocks the water inlet, the liquid in the liquid storage barrel will be retained in the liquid infusion tube under the action of pressure, and the liquid in the liquid storage barrel can be pushed into the liquid infusion tube through the squeezing mechanism, so that the liquid flows out through the micropores, thereby completing the irrigation of seeds or seedlings.

[0009] It is further defined that the squeezing mechanism includes an air pipe and an elastic air bag, the air pipe is fixedly mounted on the upper end of the liquid storage barrel, the upper section of the air pipe is arranged on the first handle, the elastic air bag is fixedly mounted on the upper part of the first handle, and the upper end of the air pipe is connected to the elastic air bag and communicates with the inside of the elastic air bag. With such a structural design, when the elastic air bag is squeezed, the air inside will enter the liquid storage barrel through the air pipe, squeeze the liquid in the liquid storage barrel, and thus push the liquid downward.

[0010] It is further defined that a separation ring is fixedly installed inside the gas delivery pipe, and the middle part of the separation ring is recessed downward. With such a structural design, the separation ring can prevent the liquid in the liquid storage barrel from flowing back into the elastic airbag.

[0011] It is further defined that a one-way air valve is fixedly connected to the elastic airbag, and a spring and a return spring are fixedly installed inside the elastic airbag. With such a structural design, after the elastic airbag is squeezed and deformed, it will return to its initial state under the elastic force of the spring and the return spring, so that the external air flows inward through the one-way air valve under the action of pressure, so as to facilitate multiple pressing and use.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] The utility model has a first iron sheet hinged with the second iron sheet, and the opening and closing of the first iron sheet and the second iron sheet can be controlled by the first handle and the second handle. When the first iron sheet and the second iron sheet are unfolded, the seeds can push the baffle to rotate under the action of gravity and fall downward from the seed conveying tube. When closed, the falling state of the seeds can be stopped, and the infusion tube can be used to sprinkle water on the seeds during sowing, which saves time and effort during sowing.

[0029] like Figure 1 to Figure 5 As shown, the utility model is a sowing device for greenhouse seedling raising and transplanting test, comprising a first iron sheet 1 and a second iron sheet 2, the lower parts of the first iron sheet 1 and the second iron sheet 2 are both sharp, and the upper parts are both semi-cylindrical, the upper parts of the first iron sheet 1 and the second iron sheet 2 are respectively fixedly installed with a first handle 3 and a second handle 4, the first iron sheet 1 is rotatably connected to the upper parts of the second iron sheet 2, a seed conveying tube 5 is fixedly installed on the inner side of the second iron sheet 2, a baffle 51 is rotatably installed on the lower end of the seed conveying tube 5, a torsion spring is provided at the junction of the baffle 51 and the seed conveying tube 5, an infusion tube 6 is fixedly installed on the inner side of the first iron sheet 1, the opening and closing states of the first iron sheet 1 and the second iron sheet 2 can be controlled by the first handle 3 and the second handle 4, so as to facilitate sowing or transplanting of seedlings, and a sowing pit can be formed on the soil after the enclosed first iron sheet 1 and the second iron sheet 2 are pressed into the soil, and seeds or seedlings can be delivered into the sowing pit when unfolded.

[0030] A liquid storage barrel 7 is fixedly installed on the inner side of the first iron sheet 1, the upper end of the infusion tube 6 is fixedly connected to the lower end output port of the liquid storage barrel 7, a partition 61 is fixedly installed at the lower end of the infusion tube 6, and micropores are opened on the partition 61. A water inlet is provided at the upper end of the liquid storage barrel 7, and a movable plug 71 is provided at the water inlet. The liquid storage barrel 7 is provided with an extrusion mechanism 72 that can squeeze the liquid in the liquid storage barrel 7 outward.

[0031] The squeezing mechanism 72 includes an air pipe 721 and an elastic air bag 722. The air pipe 721 is fixedly installed on the upper end of the liquid storage barrel 7. The upper section of the air pipe 721 is arranged on the first handle 3. The elastic air bag 722 is fixedly installed on the upper part of the first handle 3. The upper end of the air pipe 721 is connected to the elastic air bag 722 and communicates with the interior thereof.

[0032] A separation ring 7211 is fixedly installed inside the air supply pipe 721, and the middle part of the separation ring 7211 is concave downward. When the elastic airbag 722 recovers its deformation, the internal space increases and the pressure decreases. The separation ring 7211 will deform under the action of pressure, thereby closing the middle part, and can cooperate with the one-way air valve 7221 to replenish external air into the elastic airbag 722.

[0033] A one-way air valve 7221 is fixedly connected to the elastic airbag 722, and a spring 7222 and a return spring 7223 are fixedly installed inside the elastic airbag 722. The spring 7222 and the return spring 7223 can make the elastic airbag 722 quickly restore its deformation, with a simple structure and easy use.

[0034] The method of using the utility model is as follows:

[0035] When in use, the seeds and the irrigation liquid are added to the seed delivery tube 5 and the liquid storage barrel 7 respectively, and then the water inlet of the liquid storage barrel 7 is blocked by the movable plug 71, so that the irrigation liquid in the liquid storage barrel 7 cannot flow out from the micropores of the partition 61 under the action of air pressure, and the first handle 3 and the second handle 4 are held to deliver the enclosed first iron sheet 1 and the second iron sheet 2 into the soil to form a sowing pit on the soil, and at this time, the first handle 3 and the second handle 4 are used to unfold the first iron sheet 1 and the second iron sheet 2;

[0036] When the first iron sheet 1 and the second iron sheet 2 are unfolded, the seeds will push the baffle 51 to rotate under the action of gravity and fall downward from the seed delivery tube 5. When the seeds fall downward, the elastic airbag 722 on the first handle 3 is squeezed by hand, and the air in the elastic airbag 722 enters the liquid storage barrel 7 through the air delivery tube 721, pushing the irrigation liquid to flow outward through the delivery tube 6 to the micropores of the partition 61, so as to irrigate the soil at the sowing location;

[0037] After observing that a proper amount of seeds have fallen into the sowing pit, the first iron sheet 1 and the second iron sheet 2 are closed, and the baffle 51 blocks the lower pipe opening of the seed conveying pipe 5 under the resistance of the partition 61 to prevent the seeds from falling further outward;

[0038] After the pressure on the elastic airbag 722 is released, the elastic airbag 722 will quickly restore its deformation under the elastic force of the spring 7222 and the return spring 7223, and the pressure inside the elastic airbag 722 will decrease. At this time, the separating ring 7211 will be in a closed state under the action of pressure, and the external air will enter the elastic airbag 722 through the one-way air valve 7221 for subsequent use.

[0039] The above is a detailed introduction to a sowing device for greenhouse seedling raising and transplanting experiments provided by the utility model. The description of the specific embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
