[0002] As an emerging industry, home gardening is developing rapidly. The main places for home gardening are balconies and courtyards. During the growth process, horticultural plants will inevitably be invaded by pests and diseases, which will greatly reduce their ornamental value and yield. In actual families, the use of chemical pesticides will harm the health of family members and pollute the home environment, which is daunting. The use of plant water extracts for pest control is low-cost, pollution-free and effective. Its promotion in home gardening can guide green and organic planting in home gardening, and its use has huge market value potential.

[0003] The water extract of shallot can effectively prevent and control aphids. However, to prepare the water extract of shallot, the shallot needs to be crushed first, soaked in water, and stirred two to three times during the soaking process to obtain the water extract of shallot. In the process of crushing the shallot, the shallot will stick to the inner wall of the pestle and the bowl, resulting in uneven crushing. It is also necessary to manually clean the shallot residue from the pestle and the bowl, which is time-consuming and labor-intensive, and reduces the effect of the water extract of the shallot. Summary of the invention

[0004] In order to overcome the disadvantage that, in the process of preparing a plant water extract for preventing and controlling aphids, the crushing of the shrimp chives will cause the shrimp chives to stick to the pestle and the inner wall of the container, resulting in uneven crushing, the present invention provides a method for preparing a plant water extract for preventing and controlling aphids for home gardening and supporting equipment.

[0009] To further illustrate, the second iron sheet is embedded in the center of the filter cloth.

[0010] Further description: the ram body is provided with a third electromagnet.

[0011] Further description, it also includes a water pipe; the cover is fixedly connected to the water pipe; the ram body is provided with a blind hole; the lower part of the ram body is provided with a water outlet, and the water outlet is connected to the blind hole, and the water pipe is connected to the blind hole.

[0012] Further description, it also includes a rotating plate, a watering pot and a nozzle; the container is rotatably connected to the rotating plate, and the rotating plate is provided with a plurality of through holes; the container is provided with a plurality of drain holes in a circular array, and the drain holes correspond to the positions of the through holes; a watering pot is provided on the left side of the container; and a nozzle is provided above the watering pot.

[0013] Further description, the lower part of the container is provided with an inclined surface.

[0014] Further description, the present invention provides a method for preparing a plant water extract for preventing and controlling aphids, comprising the following processing steps: step 1: plant processing, selecting 30 grams of fresh plant samples of the aerial part of Scallion, cutting them into small pieces with scissors, putting them into a container, and squeezing and crushing them with a pestle body; step 2: extraction, adding 300 milliliters of clean water to the container, soaking for 24 hours, stirring three to four times with the pestle body during the period; step 3: filtering, filtering the extract through a filter cloth with a mesh number of 100 to 200 to obtain a filtrate; step 4: spraying aphids, adding the filtrate in step 3 to a spray pot, adding an equal volume of clean water to the spray pot for dilution, and then spraying it directly on the horticultural plants with aphids.

[0015] The beneficial effects of the present invention are as follows: the present invention drives the outer edge of the filter cloth to move upward by the pounding hammer body, and then keeps the middle position of the filter cloth stationary, so that the shallots are gathered in the middle position of the filter cloth, so that the subsequent pounding hammer body can hammer more shallots, and the filter cloth is deformed so that the shallots cannot stick to the filter cloth, and the pounding hammer body rotates when hammering the shallots, so that the shallots cannot stick to the pounding hammer body, thereby solving the problem that the shallots will stick to the pounding hammer and the inner wall of the container when crushing, resulting in uneven crushing.

[0016] The present invention uses the second iron sheet to bear the impact force of the ram body, thereby preventing the hammering of the ram body from over-pressing the filter cloth and damaging the filter cloth.

[0017] The present invention drives the middle position of the filter cloth to move up and down by the pounding hammer body during the soaking process of the shallot, and keeps the outer edge of the filter cloth stationary, so that the filter cloth is repeatedly deformed, so that the shallot and water are evenly mixed, and the mixture is stirred, and the water is repeatedly passed through the filter cloth, so that the water washes away the shallot juice and the shallot residue on the filter cloth.

[0018] The present invention drives the middle position of the filter cloth to move up and down by a ramming hammer body during the filtering process of the filter cloth, and keeps the outer edge of the filter cloth stationary, so that the shrimp chives cannot adhere to the filter cloth during the filtering process, so that the shrimp chives will not reduce the water flow filtered by the filter cloth, thereby making the filtering speed of the present invention faster.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0026] Example 1

[0027] A device for producing a plant water extract for preventing and controlling aphids in home gardening, such as Figure 1-3 As shown, it includes a container 1 and a lid 2; the container 1 is made of non-metallic material; the container 1 is installed with the lid 2;

[0028] It also includes a ramming hammer body 5, a power assembly and a collecting assembly; the cover 2 is connected to the power assembly; the power assembly is connected to the ramming hammer body 5, the power assembly is used to drive the ramming hammer body 5 to move upward and downward, and drive the ramming hammer body 5 to rotate; the ramming hammer body 5 is connected to the collecting unit.

[0029] The power assembly includes a slide rail 101, a slider 102, a connecting block 103, a first gear 104, a motor 105 and a second gear 106; the cover 2 is fixedly connected to two slide rails 101 symmetrically distributed front and back: the two slide rails 101 are slidably connected to a slider 102; the two sliders 102 are commonly connected to the connecting block 103; the cover 2 is rotatably connected to the first gear 104; the cover 2 is fixedly connected to the motor 105, and the output shaft of the motor 105 is fixedly connected to the first gear 104; the connecting block 103 is rotatably connected to the second gear 106, and the second gear 106 meshes with the first gear 104 after moving downward.

[0030] The collecting unit includes a sliding block 201, a rope 202, a spring telescopic rod 203 and a filter cloth 204; five circular array sliding grooves 5a are arranged at the lower part of the ram body 5, and a sliding block 201 is slidably connected in all the sliding grooves 5a; a spring telescopic rod 203 is fixedly connected in each sliding groove 5a, and one end of the spring telescopic rod 203 is fixedly connected to the sliding groove 5a, and the other end of the spring telescopic rod 203 is fixedly connected to the sliding block 201; all the sliding blocks 201 are fixedly connected with a rope 202; all the ropes 202 are commonly connected to the filter cloth 204, the outer edge of the filter cloth 204 is provided with five first iron sheets 204a arranged in a circular array, and the center position of the filter cloth 204 is provided with a second iron sheet 204b, and the shrimp chives are collected together through the filter cloth 204; five first electromagnets 1a in a circular array are arranged on the inner side of the container 1, and a second electromagnet 1b is arranged at the center position of the container 1.

[0031] The rope 202 and the filter cloth 204 are detachably connected. Since the filter cloth 204 will be hammered repeatedly by the hammer body 5, the filter cloth 204 may be broken after long-term use. The detachable connection makes it easier for humans to replace the filter cloth 204 and facilitates manual dumping of the shrimp chive residue on the filter cloth 204.

[0032] It also includes a squeezing ring 6; the cover 2 is fixedly connected to the squeezing ring 6, and the pounding hammer body 5 is located in the middle of the squeezing ring 6; the squeezing ring 6 is used to squeeze out the shrimp chive juice on the rope 202.

[0033] The second iron sheet 204b is embedded in the center of the filter cloth 204, so that when the hammer body 5 hits the shallots, the impact force of the hammer body 5 is borne by the second iron sheet 204b, thereby preventing the hammer body 5 from excessively squeezing the filter cloth 204 and damaging the filter cloth 204.

[0034] The working steps of the above-mentioned embodiment are as follows: first, the above-ground part of the shrimp chives is manually picked off, then the lid 2 is picked up, the shrimp chives are cut into pieces and placed on the filter cloth 204, and then the lid 2 is placed on the container 1, so that the lid 2 seals the top of the container 1, and then the slide rail 101 is controlled to start, and then the slide rail 101 drives the slider 102 to move upward, so that the slider 102 drives the ramming hammer body 5 to move upward through the connecting block 103, and at the same time, the second electromagnet 1b is controlled to start, and then the second electromagnet 1b attracts the second iron sheet 204b, and then the ramming hammer body 5 moves upward to pull the rope 202, and because the filter The second iron sheet 204b in the middle of the filter cloth 204 is attracted by the second electromagnet 1b, so that the middle of the filter cloth 204 cannot move upward, so that the rope 202 can only pull the outer periphery of the filter cloth 204 upward, and then the chopped shallots are gathered in the middle of the filter cloth 204; then when the arc portion below the ram body 5 moves upward to the position of the extrusion ring 6, it stops moving upward, and then the slide rail 101 is controlled to drive the ram body 5 to move downward. In the process of moving downward, the rope 202 no longer tightens the outer periphery of the filter cloth 204, so that the outer periphery of the filter cloth 204 gradually fits the inner wall of the container 1 again. When the ramming hammer body 5 moves downward and contacts the center position of the container 1, it stops moving downward. Then, since the shrimp chives have gathered in the middle position of the filter cloth 204 at this time, the ramming hammer body 5 can hammer more shrimp chives after moving downward. At this time, the first gear 104 and the second gear 106 are meshed. When the ramming hammer body 5 hammers the shrimp chives, the control motor 105 is started, which drives the first gear 104 to rotate, thereby rotating the second gear 106, and then driving the ramming hammer body 5 to rotate. Since the ramming hammer body 5 squeezes the filter cloth 204 at this time, and the rope 202 has been completely The ramming hammer body 5 is fully relaxed, so that the rotation of the ramming hammer body 5 will not drive the filter cloth 204 to rotate. When it rotates 30 to 50 degrees, it stops rotating, and then controls the motor 105 to reverse, so that the ramming hammer body 5 is reversed and reset. During this process, the filter cloth 204 scrapes off the shrimp chive debris stuck to the bottom of the ramming hammer body 5, so that when the ramming hammer body 5 hammers the shrimp chives, the shrimp chives cannot stick to the ramming hammer body 5. Then, after the ramming hammer body 5 is reset, the slide rail 101 is controlled to drive the ramming hammer body 5 to move upward again, and then move downward, and so on, so that the shrimp chives are repeatedly gathered in the middle position of the filter cloth 204 and hammered;It should be noted that after multiple hammering, the shrimp onion will stick to the filter cloth 204, and the upward movement of the outer periphery of the filter cloth 204 will cause the filter cloth 204 to deform, so that the shrimp onion cannot stick to the filter cloth 204, so that the hammered shrimp onion is also gathered in the middle of the filter cloth 204, so that the shrimp onion is crushed, and then water is manually poured into the container 1 to soak the shrimp onion, and it is stirred three to five times during the soaking process, and then after soaking for 24 hours, the crushed shrimp onion residue is filtered out to obtain the shrimp onion water extract, and then the shrimp onion water extract is poured into the spraying device, and then it is manually sprayed on the planted green plants through the spraying device to prevent and control aphids, and then the lid 2 is manually taken off from the container 1, and the shrimp onion residue on the filter cloth 204 is poured out, so as to facilitate the preparation of the shrimp onion water extract next time. ;

[0035] Since the juice of the shrimp onion will splash out during the hammering process, the rope 202 will be stained with a part of the shrimp onion juice, resulting in a reduction of the shrimp onion juice. Then, when the hammer body 5 moves upward, the squeezing ring 6 can squeeze the rope 202, and then squeeze out the shrimp onion juice in the rope 202, thereby reducing the loss of the shrimp onion juice.

[0036] Example 2

[0037] On the basis of Example 1, Figure 2 and Figure 4 As shown, a third electromagnet 5b is provided at the lower part of the ram body 5.

[0038] It also includes a water pipe 7; the cover 2 is fixedly connected to the water pipe 7; the ram body 5 is provided with a blind hole 5c; the lower part of the ram body 5 is provided with a water outlet 5d, and the water outlet 5d is connected to the blind hole 5c, and the water pipe 7 is connected to the blind hole 5c, and then water is discharged to the blind hole 5c through the water pipe 7, and then flows out from the water outlet 5d, thereby flowing downward along the surface of the ram body 5, and cleaning the shrimp chive juice on the ram body 5.

[0039] The working steps of the above embodiment are as follows: after the shrimp shallot is crushed, the faucet is manually connected to the water pipe 7, and then the faucet is turned on to release water into the blind hole 5c, and then the water flows out from the water outlet 5d, and then flows downward along the surface of the pounding hammer body 5, and then gathers at the lower center point of the pounding hammer body 5 and flows downward, thereby washing away the shrimp shallot juice on the surface of the pounding hammer body 5, and then flows into the container 1. When the water is put in, the faucet is turned off, so that the shrimp shallot is soaked in water;

[0040] During the soaking process, after a period of time, the first electromagnet 1a is controlled to start, and then the first electromagnet 1a attracts the first iron sheet 204a, and then the second electromagnet 1b is controlled to be closed, and then the second electromagnet 1b no longer attracts the second iron sheet 204b, and then the third electromagnet 5b is controlled to start, so that the third electromagnet 5b attracts the second iron sheet 204b, and then the slide rail 101 is controlled to drive the tamping hammer body 5 to move upward, and then the tamping hammer body 5 drives the center position of the filter cloth 204 to move upward through the second iron sheet 204b. The first electromagnet 1a sucks the filter cloth 204 so that the outer part of the filter cloth 204 cannot move upward. As a result, during the upward movement of the ramming hammer body 5, the rope 202 pulls the sliding block 201, so that the sliding block 201 cannot move upward. The ramming hammer body 5 moves upward, and the sliding block 201 moves downward in the sliding groove 5a relative to the ramming hammer body 5. At this time, the spring telescopic rod 203 is in a compressed state, so that the ramming hammer body 5 does not lift the outer part of the filter cloth 204 when it moves upward. When the sliding block 201 moves to the lower part of the sliding groove 5a, the ramming hammer body 5 The main body 5 stops moving upward, so that the filter cloth 204 changes from a concave arc shape to a convex arc shape, and the water passes through the filter cloth 204 and enters under the filter cloth 204, and then the slide rail 101 is controlled to drive the hammer body 5 to move downward. During the downward movement of the hammer body 5, the rope 202 no longer tightens the sliding block 201, and then the spring telescopic rod 203 resets and pushes the sliding block 201 to move upward. When the filter cloth 204 is in contact with the inner wall of the container 1 again, it stops moving downward, so that the filter cloth 204 changes from a convex arc shape to a concave arc shape again. At this time, the water that has entered under the filter cloth 204 passes through the filter cloth 204 again and flows to the top of the filter cloth 204, and washes the shallots on the filter cloth 204 to the surroundings of the container 1, and then the slide rail 101 is controlled again to drive the hammer body 5 to move upward, and so on, so that the shallots and water are mixed evenly, and the stirring is completed. The water repeatedly passes through the filter cloth 204, so that the water rinses the shallot juice and the shallot residue on the filter cloth 204, and then after a certain period of time, the stirring is stopped. It should be noted that three to five stirrings need to be completed during the soaking process.

[0041] Example 3

[0042] On the basis of Example 2, Figure 3As shown, it also includes a rotating plate 301, a spray pot 3 and a nozzle 4; the rotating plate 301 is rotatably connected to the lower part of the container 1, and the rotating plate 301 is provided with five through holes 301a in a circular array; five water discharge holes 1c in a circular array are provided between the second electromagnet 1b of the container 1 and the five first electromagnets 1a, and the water discharge holes 1c correspond to the positions of the through holes 301a, and the through holes 301a and the water discharge holes 1c cooperate with each other, and the water extract of shallots is released by aligning the through holes 301a with the water discharge holes 1c; a spray pot 3 is provided on the left side of the container 1; and a nozzle 4 is provided above the spray pot 3.

[0043] The lower part of the container 1 is provided with an inclined surface, so that a person can place the container 1 on the spray pot 3 better.

[0044] The working steps of the above embodiment are as follows: after the shrimp chives are soaked for 24 hours, the container 1 and the cover 2 are manually lifted and moved to the top of the spray pot 3, and then the container 1 and the cover 2 are placed on the spray pot 3, forming a Figure 5 The state shown is shown, and then the rotating plate 301 is manually toggled, so that the through hole 301a is aligned with the drain hole 1c, and then the water extract of the shallot in the container 1 flows out from the drain hole 1c and the through hole 301a, so that the water extract of the shallot needs to pass through the filter cloth 204 to enter the spray pot 3, so as to separate the shallot residue from the water, and then because the shallot residue cannot pass through the filter cloth 204, the shallot will be squeezed by the water flow and attached to the filter cloth 204, so that the water flow passing through the filter cloth 204 is reduced, and then in the filter During the process, the first electromagnet 1a is controlled to start, and then the first electromagnet 1a sucks the first iron sheet 204a, thereby fixing the periphery of the filter cloth 204, and then the third electromagnet 5b is controlled to start, so that the third electromagnet 5b sucks the second iron sheet 204b, and then the ramming hammer body 5 is driven to move up and down repeatedly through the slide rail 101, thereby driving the middle position of the filter cloth 204 to move up and down repeatedly, so that the filter cloth 204 shakes, which is convenient for the shrimp onion water extract to flow out and prevents the shrimp onion residue from settling and clogging the filter cloth 204.

[0045] Then, after the water extract of shallots flows into the spray pot 3, the faucet connected to the water pipe 7 is opened, so that water is released into the spray pot 3 through the container 1, thereby diluting the water extract of shallots. When the water in the spray pot 3 is full, the faucet is closed to complete the dilution of the water extract of shallots, and then the nozzle 4 is covered and then sprayed on the plants to prevent and control aphids.
