Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, in particular to salt-alkali resistance experimental equipment for the early growth stage of crops. Background Art

[0002] Crops, short for agricultural crops, refer to the general term for plants that are planted or harvested on a large scale by humans for their fruits, seeds, leaves, modified roots, stems and flowers for profit or food.

[0003] In order to cultivate excellent crop products, seedlings in the early stage of crop growth, commonly known as crop seedlings, are generally planted inside a crop breeding experimental box, and the temperature, humidity, light, carbon dioxide and rhizosphere nutrition around the seedlings are precisely controlled through intelligent environmental control equipment and nutrient solution circulation systems. In this way, the seedlings are placed in a variety of different environments, and artificial intervention is carried out according to the growth status of the seedlings to guide the growth of the seedlings and strengthen certain characteristics of the seedlings. For example, the environmental conditions of saline-alkali land are simulated, and excellent germplasm resources suitable for saline-alkali land are selected to improve the salt-alkali resistance of the seedlings. This crop breeding experimental box that can simulate a saline-alkali environment can be called a salt-alkali resistance experimental equipment in the early stage of crop growth.

[0004] However, when using this salt-alkali tolerance experimental equipment for the early growth of crops, the staff needs to move one by one to the position where the crop seedlings are planted to operate. This operation process is relatively cumbersome, which affects the work efficiency of the staff. When crops need to be planted in other types of soil, in order to prevent cross contamination, the containers used to plant crops need to be manually cleaned to remove the soil remaining on the inner wall of the container. This process further increases the cumbersomeness of using this equipment. The seedlings inside this breeding experimental box are all in the same temperature environment, but the saline-alkali land in the outside world is distributed in different areas, and the temperature difference of the saline-alkali land in different areas is large, which leads to the breeding experimental box can only simulate the temperature of the saline-alkali land in a certain area at a time, and it has high limitations. When it is necessary to detect the growth of crops planted on land with a certain salinity concentration under different temperature environments, it can only be tested multiple times, and the test process is time-consuming; therefore, it does not meet the existing needs. For this reason, we propose a salt-alkali tolerance experimental equipment for the early growth of crops. Summary of the invention

[0040] A plurality of storage grooves 6 are arranged in a ring shape on the outer side of the upper end surface of the circular table 5, and a plurality of crop planting tubes 7 are respectively located inside the plurality of storage grooves 6. The interior of each crop planting tube 7 contains saline-alkali soil 8. The pushing mechanism can push the crop planting tubes 7 moved to the front of the experimental table 16 into the interior of the arc groove 17 in the process of driving the circular table 5 to rotate around the center point of the lower end surface.

[0041] The one-by-one pushing mechanism includes a replacement motor 3, the output shaft of the replacement motor 3 is connected to the replacement shaft 4 through a coupling, and the upper end surface of the replacement shaft 4 is connected to the center point of the lower end surface of the circular table 5; when it is necessary to cultivate crops with strong salt-alkali resistance, the crops are planted inside the saline-alkali soil 8, and the temperature and humidity around the salt-alkali resistant land are simulated by the crop breeding experimental box 1. When it is necessary to conduct experimental operations on the crops planted inside the crop planting tube 7 one by one, the replacement motor 3 is started, and the replacement motor 3 can drive the circular table 5 connected to it through the replacement shaft 4 to rotate. When the circular table 5 rotates, the crop planting tube 7 inside the storage groove 6 located on the upper end surface of the circular table 5 will revolve around the replacement shaft 4.

[0042] A circular metal block 14 is provided at the rear of the replacement motor 3. The circular metal block 14 is circular, and a support rod is fixedly provided at the middle position of the lower end surface of the circular metal block 14, and the lower end surface of the support rod is fixed to the lower inner wall of the crop breeding experimental box 1; a push metal ring 15 is fixedly sleeved on the lower side of the outer surface of the crop planting tube 7, and the front end surface of the push metal ring 15 located on the far right is in contact with the rear end surface of the circular metal block 14; with the revolution of the crop planting tube 7, the push metal ring 15 fixedly sleeved on the lower side of the outer surface of the crop planting tube 7 will contact the outer surface of the circular metal block 14, and move toward the direction of the experimental table 16 under the push of the circular outer surface of the circular metal block 14. When the crop planting tube 7 moves to the front of the experimental table 16, This crop planting tube 7 will completely enter the interior of the arc groove 17 located on the front end surface of the experimental table 16. When this crop planting tube 7 completely enters the interior of the arc groove 17, the replacement motor 3 is turned off and the further movement of the crop planting tube 7 is stopped. Through the above technical solution, multiple crop planting tubes 7 can be pushed one by one into the interior of the arc groove 17 located on the front end surface of the experimental table 16. The staff only needs to sit around the experimental table 16 to perform experimental operations on the crops planted in different crop planting tubes 7 one by one. This structure improves the convenience of the equipment, so that the staff no longer needs to move to perform experimental operations on the crops planted in different crop planting tubes 7. While improving the work efficiency of the staff, it makes the work of the staff easier.

[0043] A spring groove 10 located inside the circular platform 5 is provided on one side of the crop planting tube 7, a metal ring 12 is provided inside the spring groove 10, a reset rod 11 is connected to the axis of the metal ring 12, a spring 13 is sleeved on one side of the outer surface of the reset rod 11, and the two ends of the spring 13 are respectively connected to the metal ring 12 and the inner wall of the spring groove 10, and the reset rod 11 is fixed to the crop planting tube 7 facing the nearest crop planting tube 7; as the crop planting tube 7 moves, the reset rod 11 fixed thereto and the metal ring 12 fixedly sleeved on the outer surface of the reset rod 11 will move with it. Move toward the direction of the arc groove 17. As the metal ring 12 moves, the metal ring 12 will squeeze the spring 13 connected to it. When the staff needs to conduct experimental operations on the crops planted in different crop planting tubes 7, the replacement motor 3 is started again to rotate the circular table 5. As the circular table 5 rotates, the crop planting tube 7 in the arc groove 17 will gradually move outward. With the movement of this crop planting tube 7 and the reaction force of the squeezed spring 13, this crop planting tube 7 can be pulled into the storage groove 6 for storage.

[0044] A guide rod 9 fixed to the outer surface of the crop planting tube 7 is provided above the reset rod 11 , and the guide rod 9 is movably inserted into the interior of the circular platform 5 ; the guide rod 9 can ensure the stability of the moving crop planting tube 7 .

[0045] A semicircular positioning groove 24 is provided on one side of the outer surface of the pushing metal ring 15, and a fixing threaded rod 18 connected to the experimental table 16 through a threaded structure is provided behind the semicircular positioning groove 24 closest to the arc groove 17, and a clamping rod 19 is fixedly provided in the middle position of the front end surface of the fixing threaded rod 18, and a positioning spring 23 is sleeved on one side of the outer surface of the clamping rod 19, and a positioning metal ball 20 is connected to the front end surface of the positioning spring 23, and a through hole 21 is provided in the middle position of the front end surface of the positioning metal ball 20, and the positioning metal ball 20 is movably sleeved on the outer surface of the clamping rod 19 through the through hole 21;

[0046] The front end of the positioning metal ball 20 is inserted into the semicircular positioning groove 24 closest to the arc groove 17, and a slot 22 is provided on one side of the inner wall of the semicircular positioning groove 24; when the crop planting tube 7 moves to the front of the experimental table 16 and completely enters the arc groove 17, the positioning metal ball 20 will also be inserted into the semicircular positioning groove 24 of the outer surface of the pushing metal ring 15 fixedly sleeved on the lower side of the outer surface of the crop planting tube 7 under the action of the spring force of the positioning spring 23 connected thereto, and the positioning metal ball 20 inserted into the semicircular positioning groove 24 can position the crop planting tube 7 to prevent its position from deviating;

[0047] If the staff is a novice and is not familiar with the experimental operation steps, and always accidentally pushes the crop planting tube 7 to move during the experimental operation, the fixed threaded rod 18 can be rotated. Driven by the threaded structure, the fixed threaded rod 18 will move back and forth accordingly. At this time, the fixed threaded rod 18 is moved forward. As the fixed threaded rod 18 moves forward, the clamping rod 19 fixed to the front end face of the fixed threaded rod 18 will be clamped into the inside of the clamping groove 22 on the inner wall of the semicircular positioning groove 24, so as to fix the crop planting tube 7 located in the arc groove 17. By fixing the crop planting tube 7, the stability of the crop planting tube 7 can be ensured, and the crop planting tube 7 can be prevented from moving due to the experimental operation of the staff.

[0048] A breeding trough cleaning mechanism 2 is fixedly installed on the lower end surface of each crop planting tube 7. The breeding trough cleaning mechanism 2 includes a cylindrical metal shell 201, a metal tube 206, a plurality of annular cleaning sponges 207, two small spray heads 208, two concave water source transmission pipes 209, a cleaning water 210, a cylindrical groove 211 and a synchronous transmission mechanism. The cylindrical groove 211 is located in the middle position of the upper end surface of the cylindrical metal shell 201, the cleaning water 210 is located inside the cylindrical groove 211, and the metal tube 206 is located in the middle position inside the cleaning water 210. The two small spray heads 208 are respectively fixedly installed at the two ends of the upper side of the outer surface of the metal tube 206, and the two concave water source transmission pipes 209 are respectively connected to the two small spray heads 208, and the small spray heads 208 are communicated with the cleaning water 210 located on the lower side of the cylindrical groove 211 through the concave water source transmission pipe 209;

[0049] A plurality of annular cleaning sponges 207 are fixedly sleeved on the outer surface of the metal tube 206 in sequence from top to bottom, and the synchronous transmission can make the metal tube 206 move up and down in the process of driving the metal tube 206 to rotate.

[0050] The cylindrical metal shell 201 is installed on the lower side of the outer surface of the crop planting tube 7 through a threaded structure, and the inner wall diameter of the bottom end of the crop planting tube 7 is smaller than the inner wall diameter of the middle position and the top end of the crop planting tube 7; when the breeding trough cleaning mechanism 2 has been used ten times, it is necessary to remove the cylindrical metal shell 201 through the threaded connection structure between the cylindrical metal shell 201 and the crop planting tube 7, and replace the cleaning water 210.

[0051] A sealing plate 212 is fixedly provided on the upper end surface of the metal tube 206, and the outer surface of the sealing plate 212 is in contact with the inner wall of the bottom end of the crop planting tube 7; the sealing plate 212 can carry the saline-alkali soil 8 inside the crop planting tube 7 and isolate the saline-alkali soil 8 from the cleaning water 210 inside the cylindrical groove 211, thereby preventing the two from mixing;

[0052] Since the outer surface of the sealing plate 212 is in contact with the inner wall of the bottom end of the crop planting tube 7, the sealing plate 212 moving upward can be prevented from contacting the inner wall at the middle position and the top end position of the crop planting tube 7, thereby pushing the saline-alkali soil 8 contaminated on the inner wall of the crop planting tube 7 to the upper end surface of the sealing plate 212, resulting in the inability to store the residual saline-alkali soil 8.

[0053] The synchronous transmission mechanism includes a stepper motor 202, the output shaft of the stepper motor 202 is connected to a square shaft 203 through a coupling, a threaded lifting rod 204 connected to the cylindrical metal shell 201 through a threaded structure is provided on the outer side of the square shaft 203, a square slot 205 is provided in the middle of the lower end surface of the threaded lifting rod 204, the square shaft 203 is inserted into the square slot 205, and the upper end surface of the threaded lifting rod 204 is fixed to the metal tube 206;

[0054] The cross-sectional shape of the square shaft 203 is a square, and the outer surface of the square shaft 203 fits with the inner wall of the square slot 205, and the square shaft 203 and the square slot 205 are slidably connected; when it is necessary to plant crops through different soils inside the crop planting tube 7, first use a shovel or other similar tools to clean up the saline-alkali soil 8 inside the crop planting tube 7, and then start the stepper motor 202, and the stepper motor 202 can drive the square shaft 203 connected thereto to rotate. Since the outer surface of the square shaft 203 fits with the inner wall of the square slot 205 located at the lower end face of the threaded lifting rod 204, when the square shaft 203 rotates, the threaded lifting rod 204 will rotate along with it, and driven by the threaded structure , the rotating threaded lifting rod 204 will move upward or downward while rotating. When the threaded lifting rod 204 moves upward while rotating, the metal pipe 206 fixed thereto will also move upward while rotating. As the metal pipe 206 rises, the small spray head 208 fixed on the outer surface of the metal pipe 206 will enter the interior of the crop planting pipe 7. The small spray head 208 can extract the cleaning water 210 located inside the cylindrical groove 211 through the concave water source transmission pipe 209 and spray it on the inner wall of the crop planting pipe 7. The cleaning water 210 sprayed on the inner wall of the crop planting pipe 7 will flow into the interior of the cylindrical groove 211 again under the action of gravity, so as to recycle the cleaning water 210;

[0055] As the metal tube 206 rotates and rises, the annular cleaning sponge 207 fixed on the outer surface of the metal tube 206 will enter the interior of the crop planting tube 7 and contact the wetted inner wall of the crop planting tube 7 to wipe the inner wall of the crop planting tube 7. When the metal tube 206 can no longer be moved upward, the square rotating shaft 203 connected to it is driven by the stepper motor 202 to rotate in the opposite direction, so as to move the metal tube 206 downward while rotating, and wipe the inner wall of the crop planting tube 7 again. When the metal tube 206 has been cyclically moved up and down for ten minutes, First, wait for the cleaning water 210 inside the crop planting tube 7 to completely flow into the cylindrical groove 211, and then move the sealing plate 212 back to its original position to isolate the crop planting tube 7 from the cylindrical groove 211. The above technical solution can improve the efficiency and convenience of the breeding process. The automated cleaning process can reduce manual operations, save time and labor, and at the same time ensure the cleanliness of each crop planting tube 7, providing a clean and consistent environment for the next round of crop planting. In addition, this automated cleaning function can also reduce human errors and omissions, and improve the consistency and accuracy of the experiment.

[0056] A planting tube partition temperature adjustment mechanism is fixedly installed in the middle position of the upper end surface of the highly portable experimental mechanism. The planting tube partition temperature adjustment mechanism includes a circular column 25, a 27, a plurality of synchronous connection mechanisms of the same number as the crop planting tubes 7, an arc plate 28, a lifting platform 30, a transparent sealing cover 31 and a temperature control mechanism 32. The metal ring 27 is sleeved on the upper side of the outer surface of the circular column 25 through a roller bearing, and the plurality of arc plates 28 are respectively located above the plurality of crop planting tubes 7, and the arc plates 28 are connected to the metal rings 27 through the synchronous connection mechanism.

When the crop planting tubes 7 move, the corresponding curved plates 28, lifting platforms 30, transparent sealing covers 31 and temperature control mechanisms 32 will move together through the synchronous connection mechanism.

[0058] By covering the upper end surface of the crop planting tube 7 with a transparent sealing cover 31, a small sealed space can be formed, and the temperature inside the small sealed space can be adjusted by the temperature control mechanism 32 installed on the inner wall of the transparent sealing cover 31. The above technical solution can simultaneously simulate the actual temperature conditions of saline-alkali land in various regions, providing conditions closer to the natural environment for crop breeding experiments. In addition, through zoned temperature control, multiple experiments under different temperature conditions can be carried out in the same experimental box at the same time, without the need to repeat the experiment many times, which not only saves time and resources, but also improves the experimental efficiency. At the same time, by separately controlling the temperature inside each crop planting tube, the experimental error caused by environmental differences can be reduced. This temperature adjustment helps to obtain more reliable and repeatable experimental results, and provides more accurate data support for crop breeding research.

[0059] When it is necessary to open the small sealed space to conduct experiments on the crops planted inside the crop planting tube 7 , the transparent sealing cover 31 can be pulled upwards by the lifting platform 30 .

[0061] A small circulation fan 33 installed on the outer surface of the transparent sealing cover 31 can flow the air inside the small sealed space at a specific time every day, so as to prevent the growth of bacteria caused by long-term air stagnation;

[0062] The synchronous connection mechanism includes a synchronous ring 34, a connecting and fixing rod 35 is fixedly arranged on one side of the upper end surface of the synchronous ring 34, the upper end surface of the connecting and fixing rod 35 is fixed to the arc plate 28 located above it, a square guide rod 29 is fixedly arranged on one side of the outer surface of the arc plate 28, and the square guide rod 29 is movably inserted into the interior of the metal ring 27; when a crop planting tube 7 moves due to the one-by-one pushing mechanism, the synchronous ring 34 fixed thereto will move along with it, and when the synchronous ring 34 moves, the arc plate 28 connected thereto by the connecting and fixing rod 35 and the lifting platform 30, transparent sealing cover 31, temperature control mechanism 32, small circulation fan 33 and temperature sensor 36 fixed to the lower end surface of the arc plate 28 will move synchronously with it, and this synchronous connection mechanism can prevent the transparent sealing cover 31 covering the upper end surface of the crop planting tube 7 from getting stuck in the crop planting tube 7 and making it unable to move.
