[0015] A method for using a tomato grafted seedling raising device, comprising the tomato grafted seedling raising device according to any one of claims 1 to 3, characterized in that it comprises the following steps:

[0016] Step 1: First, install the grid plate on the inner side of the first culture rack, then fill the grid plate with cultivation soil, and then plant the grafted tomato seedlings on the grid plate. After the cultivation is completed, the water pump works to pump the irrigation water stored in the water storage chamber into the pumping pipe, and then the irrigation water is input into the water delivery pipe through the pumping pipe under the action of the water pump, and then input into the inner side of the sprinkler pipe through the water delivery pipe, and then sprayed out through the nozzle, so as to realize the sprinkler irrigation treatment of the grafted tomato seedlings;

[0017] Step 2: When the tomato grafted seedlings need to photosynthesize, the first motor works to rotate the first driving gear connected to its output, and then the first driving gear rotates to drive the rack to move. Since the rack is fixedly installed at the bottom of the inner connecting strip, when the rack moves, it drives the slide bar to slide on the inner side of the slide rail through the connecting strip, and the racks on both sides move toward each other under the rotation of the first driving gear, so that the rack can drive the first culture rack and the second culture rack to move toward each other, so that the two culture racks are staggered, which is convenient for the subsequent tomato grafted seedlings to perform better photosynthesis;

[0018] Step three: When a large amount of sewage is generated during the irrigation of grafted tomato seedlings, the sewage seeps out through the filter holes at the bottom of the culture rack, and then falls into the inner side of the water storage chamber. When the sewage falls into the inner side of the water storage chamber, it will pass through the guide seat, and perform simple diversion treatment through multiple diversion grooves evenly distributed on the top of the guide seat, and then cooperate with the multiple arc grooves set at the bottom of the diversion groove to perform preliminary filtering treatment on impurities such as soil mixed in the sewage. Then, the sewage after preliminary treatment passes through the second filter plate, and then uses the second filter plate for further filtering treatment, and then cooperates with the multiple adsorption balls distributed below it to further realize the adsorption and impurity removal treatment of the sludge. The treated sewage finally passes through the first filter plate for final purification and filtration treatment, which is convenient for the subsequent recycling and reuse of sewage.

[0019] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0020] 1. By setting the first motor, the first driving gear, the rack and the culture rack, the two culture racks can be conveniently moved toward each other in the future, so as to facilitate the subsequent photosynthesis of the tomato seedlings cultured in the culture racks, and prevent the two fixed culture racks arranged in parallel from affecting the normal photosynthesis of the subsequent grafted tomato seedlings, thereby improving the effect of cultivating the grafted tomato seedlings, and the overall practicality is higher. When the first motor is working, the first driving gear connected to its output end will rotate accordingly. At this time, the rotation of the first driving gear drives the racks meshing at both ends to move accordingly, and the racks on both sides move toward each other during the movement, so the two culture racks arranged in parallel will also move toward each other, so that the culture racks are staggered, so as to prevent the subsequent parallel culture racks from affecting the normal photosynthesis of the grafted tomato seedlings, and the overall practicality is higher.

[0021] 2. By setting the second motor, the second driving gear, the driven gear and the lamp body, it is convenient to perform better lighting treatment on the grafted tomato seedlings according to the actual lighting needs, so as to change the lighting environment of the grafted tomato seedlings, so as to better improve the cultivation effect of the grafted tomato seedlings. Since the driven gear is rotatably connected with the incubator through the shaft, when the second motor works to rotate the second driving gear connected to its output end, the meshing connection between the second driving gear and the driven gear can facilitate the subsequent rotation of the driven gear, and then the rotation of the driven gear can facilitate the subsequent adjustment of the angle of the lamp body, and then the lighting range of the lamp body can be adjusted, so as to perform better lighting treatment on the grafted tomato seedlings in different areas and change the production environment of the grafted tomato seedlings;

[0022] 3. Through the filter plate, adsorption ball, guide seat and other structures, it is convenient to effectively filter and purify the excess sewage seeping out when spraying the grafted tomato seedlings, so as to realize the recycling and reuse of sewage, reduce the consumption of water resources, and have higher overall practicality. When the sewage falls into the bottom inner side of the incubator, the sewage first falls into the multiple guide grooves opened on the surface of the guide seat. At this time, the multiple arc grooves set in the guide groove can be used to achieve preliminary filtering and treatment of the sewage, and then the second filter plate is used to further filter and purify the sewage. The sewage after filtration is finally filtered and purified under the action of the adsorption ball and the first filter plate, which is convenient for the subsequent recycling and reuse of the treated sewage.

[0034] During operation, the grid plate 10 is first installed on the inner side of the first culture rack 5, and then the cultivation soil is filled on the grid plate 10. At this time, the grafted tomato seedlings are cultivated on the grid plate 10. After the cultivation is completed, when the grafted tomato seedlings need to be photosynthesized, the first motor 2 is used to rotate the first driving gear 3 connected to its output end. At this time, since the first driving gear 3 and the rack 8 are meshed, when the first driving gear 3 rotates, it will drive the rack 8 to move horizontally. At this time, the movement of the rack 8 drives the connecting bar 6 to move synchronously. Since the connecting bar 6 and the sliding bar 7 are fixedly connected, Under the action of the connecting strip 6, the sliding strip 7 can realize synchronous movement, and then the sliding strip 7 slides along the slide rail 4, so as to realize the extension of the first culture rack 5 to the outside. Since the racks 8 symmetrically distributed on both sides are meshed and connected with the first driving gear 3, the two parallel first culture racks 5 and the second culture racks 9 can realize the extension processing towards each other under the rotation action of the first driving gear 3, so as to prevent the lower culture rack from being shaded and affecting the normal photosynthesis of the subsequent tomato grafted seedlings. The setting of the temperature sensor 12 can be used to monitor the temperature in the incubator 1 in real time to prevent the death of the tomato grafted seedlings due to excessive temperature.

[0035] The adjustment structure includes a fixing seat 13, a second motor 14, a second driving gear 15, a driven gear 16, teeth 17 and a lamp body 18. The fixing seat 13 is fixedly mounted on one side of the top of the incubator 1, and the second motor 14 is fixedly mounted on the side wall of the fixing seat 13. The output end of the second motor 14 is connected to the second driving gear 15, and the top side of the second driving gear 15 is connected to the driven gear 16. The driven gear 16 is rotatably connected to the incubator 1 through a shaft. The outer surface of the driven gear 16 is provided with teeth 17, and the surface of the driven gear 16 on the side away from the teeth 17 is fixed with the lamp body 18.

[0036] During operation, when it is necessary to adjust the lighting range of the lamp body 18, the second motor 14 works to rotate the second driving gear 15 connected to its output end. At this time, since the second driving gear 15 is meshed with the driven gear 16 through the teeth 17, the rotation of the driven gear 16 can be realized when the second driving gear 15 rotates, and then the rotation of the driven gear 16 is used to realize the subsequent adjustment of the angle of the lamp body 18, so that the lamp body 18 can be adjusted according to actual lighting needs.

[0037] A water storage chamber 19 is provided at the inner side of the bottom of the incubator 1, and a first filter plate 20 is provided in the inner cavity of the water storage chamber 19, adsorption balls 21 are distributed above the first filter plate 20, and a second filter plate 22 is distributed above the adsorption balls 21, and a flow guide seat 23 is provided at a side of the second filter plate 22 away from the adsorption balls 21, and a diversion groove 24 is provided on the inclined surface of the diversion groove 23, and an arc groove 25 is provided at the bottom of the diversion groove 24;

[0038] During operation, when excess water is generated when irrigating the grafted tomato seedlings, the excess water will be mixed with impurities such as soil and fall into the inner side of the water storage chamber 19. At this time, the sewage falls into the surface of the guide seat 23, and the multiple diversion grooves 24 opened on the surface of the guide seat 23 can realize the preliminary diversion treatment of the sewage. Then, the diverted sewage is preliminarily filtered through the arc groove 25. After the preliminary treatment, the second filter plate 22 can be used to further filter the sewage, and then the multiple adsorption balls 21 arranged in parallel can be used to further filter and purify the sewage. Finally, the first filter plate 20 can be used to better filter and remove impurities from the sewage, which is convenient for the subsequent recycling of sewage and reduces the consumption of water resources.

[0039] A water extraction pipe 26 is connected to the bottom of the back of the incubator 1, and a water pump 27 is connected to the other end of the water extraction pipe 26. The end of the water pump 27 away from the water extraction pipe 26 is connected to a water delivery pipe 28, and the other end of the water delivery pipe 28 is connected to a spray pipe 29. A nozzle 30 is arranged at the bottom of the spray pipe 29. The nozzles 30 are equidistantly distributed at the bottom of the spray pipe 29, and the spray pipe 29 is connected to the water delivery pipe 28.

[0040] During operation, the water pump 27 pumps the irrigation water stored in the water storage chamber 19 into the inner side of the pumping pipe 26. Subsequently, under the action of the water pump 27, the irrigation water in the pumping pipe 26 is input into the inner side of the water delivery pipe 28, and then input into the inner side of the spray pipe 29 through the water delivery pipe 28, so as to facilitate subsequent spraying through the nozzle 30, thereby realizing the irrigation treatment of the grafted tomato seedlings.

[0041] The first driving gear 3 is meshed with the rack 8, and the first driving gear 3 is symmetrically distributed along the vertical center line of the incubator 1;

[0042] During operation, since the first driving gear 3 is meshed with the rack 8 through the teeth 17, when the first driving gear 3 rotates, the rack 8 is driven to move accordingly, and then the movement of the rack 8 is used to drive the first culture rack 5 to extend.

[0043] The first culture rack 5 is slidably connected to the slide rail 4 via the slide bar 7, and the first culture rack 5 and the second culture rack 9 are divided into a flat shape;

[0044] During operation, the first culture rack 5 can slide along the slide rail 4 via the slide bar 7, so as to facilitate the subsequent extension of the first culture rack 5 to the outside, so as to facilitate the subsequent tomato grafted seedlings to perform better photosynthesis.

[0045] The mesh plate 10 is slidably connected to the first culture rack 5, and the outer diameter of the mesh plate 10 is matched with the size of the groove formed on the inner wall of the first culture rack 5;

[0046] During operation, since the mesh plate 10 and the first culture rack 5 are slidably connected via the grooves, the mesh plate 10 can be disassembled and replaced later, which is convenient and quick.

[0047] The second driving gear 15 is meshed with the driven gear 16 through the teeth 17, and the driven gear 16 is rotationally connected with the incubator 1 through the shaft;

[0048] During operation, when the second driving gear 15 rotates under the action of the second motor 14, the driven gear 16 can be rotated by the meshing connection between the second driving gear 15 and the driven gear 16, which facilitates the subsequent adjustment of the angle of the lamp body 18 by the rotation of the driven gear 16.

[0049] The diverter grooves 24 are evenly distributed along the inclined surface of the guide seat 23, and the arc grooves 25 are evenly distributed at the bottom of the diverter grooves 24, and the arc grooves 25 and the guide seat 23 form an integrated structure;

[0050] During operation, since the diversion grooves 24 are evenly distributed on the inclined surface of the guide seat 23, when the sewage falls onto the surface of the guide seat 23, it will be simply diverted through the diversion grooves 24, and then the preliminary filtering treatment of the sewage can be achieved by cooperating with the multiple arc grooves 25 evenly spaced at the bottom of the diversion grooves 24.

[0051] Specific working principle:

[0052] First, install the grid plate 10 on the inner side of the first culture rack 5, and then fill the cultivation soil on the grid plate 10. At this time, the grafted tomato seedlings are cultivated on the grid plate 10. After the cultivation is completed, when the grafted tomato seedlings need to be photosynthesized, the first motor 2 is used to realize the rotation of the first driving gear 3 connected to its output end. At this time, since the first driving gear 3 and the rack 8 are meshed, when the first driving gear 3 rotates, it will drive the rack 8 to move horizontally. At this time, the movement of the rack 8 drives the connecting bar 6 to move synchronously. Since the connecting bar 6 and the sliding bar 7 are fixedly connected, the synchronous movement of the sliding bar 7 can be realized under the action of the connecting bar 6, and then the sliding bar 7 moves along the sliding bar. The rail 4 slides, thereby realizing the extension of the first culture rack 5 to the outside, and since the racks 8 symmetrically distributed on both sides are meshed and connected with the first driving gear 3, the two parallel first culture racks 5 and the second culture racks 9 can realize the extension processing towards each other under the rotation of the first driving gear 3, so as to prevent the culture racks set below from being shaded and affecting the normal photosynthesis of the subsequent tomato grafted seedlings, and the setting of the temperature sensor 12 can be used to monitor the temperature in the incubator 1 in real time to prevent the tomato grafted seedlings from dying due to excessive temperature, and when it is necessary to adjust the lighting range of the lamp body 18, the second motor 14 works to rotate the second driving gear 15 connected to its output end, and at this time, due to the second driving gear The wheel 15 is meshed with the driven gear 16 through the teeth 17, so when the second driving gear 15 rotates, the driven gear 16 can be rotated, and then the rotation of the driven gear 16 is used to adjust the angle of the lamp body 18, so that the lamp body 18 can be adjusted according to the actual lighting needs. When the tomato grafted seedlings are irrigated, the water pump 27 works to pump the irrigation water stored in the water storage chamber 19 into the inner side of the pumping pipe 26, and then the irrigation water in the pumping pipe 26 is input into the inner side of the water delivery pipe 28 under the action of the water pump 27, and then input into the inner side of the spray pipe 29 through the water delivery pipe 28, so as to facilitate the subsequent spraying through the nozzle 30, so as to realize the irrigation of the tomato grafted seedlings. When excess water is generated during irrigation of grafted tomato seedlings, the excess water will be mixed with impurities such as soil and fall into the inner side of the water storage chamber 19. At this time, the sewage falls into the surface of the guide seat 23, and the multiple diversion grooves 24 opened on the surface of the guide seat 23 can realize the preliminary diversion treatment of the sewage. Subsequently, the diverted sewage is preliminarily filtered through the arc groove 25. After the preliminary treatment, the second filter plate 22 can be used to further filter the sewage, and then the multiple adsorption balls 21 arranged in parallel can be used to further filter and purify the sewage. Finally, the first filter plate 20 can be used to better filter and remove impurities from the sewage, which is convenient for the subsequent recycling of the sewage and reduces the consumption of water resources.

Then, under the action of the water pump (27), the irrigation water is input into the water delivery pipe (28) through the pumping pipe (26), and then input into the inner side of the spray pipe (29) through the water delivery pipe (28), and then sprayed out through the nozzle (30), thereby realizing the spray irrigation treatment of the grafted tomato seedlings; Step 2: When it is necessary to photosynthesize the grafted tomato seedlings, the first motor (2) works to rotate the first driving gear (3) connected to its output, and then the first driving gear (3) rotates to drive the rack (8) to move. Since the rack (8) is fixedly mounted at the bottom of the inner connecting bar (6), when the rack (8) moves, it drives the slide bar (7) to slide on the inner side of the slide rail (4) through the connecting bar (6), and the racks (8) on both sides move towards each other under the rotation of the first driving gear (3), so that the rack (8) can drive the first culture rack (5) and the second culture rack (9) to move towards each other, so that the two culture racks are staggered, so as to facilitate the subsequent better photosynthesis of the grafted tomato seedlings. Step 3: When a large amount of sewage is generated during the irrigation of the grafted tomato seedlings, the sewage seeps out through the filter holes (11) provided at the bottom of the culture rack, and then falls into the inner side of the water storage chamber (19). When the sewage falls into the inner side of the water storage chamber (19), it passes through the guide seat (23), and undergoes simple diversion treatment through a plurality of diversion grooves (24) evenly distributed at the top of the guide seat (23). Subsequently, the impurities such as mud mixed in the sewage can be initially filtered by the plurality of arc grooves (25) provided at the bottom of the diversion grooves (24). Subsequently, the sewage after the initial treatment passes through the second filter plate (22), and then further filtered by the second filter plate (22), and then further adsorbed and impurity-removed by the plurality of adsorption balls (21) distributed below the second filter plate. Finally, the treated sewage passes through the first filter plate (20) for final purification and filtration treatment, which is convenient for subsequent recycling and reuse of the sewage.
