DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] Example 1

[0029] A simple experimental device for bean seed germination, such as Figure 1 As shown, it includes a box body 1 and a box door 2, both of which are made of translucent material and are provided with ventilation holes; a water outlet bucket 31 is installed on the top surface of the box body 1, and the water in the water outlet bucket 31 is used for watering beans; the water outlet bucket 31 is connected to the box body 1 through a water outlet pipe 32, and the water in the water outlet bucket 31 enters the box body 1 through the water outlet pipe 32; a water storage bucket 4, a seedling tray 5 and a water receiving bucket 6 are arranged in sequence from top to bottom in the box body 1, the water storage bucket 4 is used to receive water and then pour it onto the seedling tray 5, the seedling tray 5 is used for bean growth, and the water receiving bucket 6 is used to collect water dripping from the seedling tray 5; a barrel cover 33 is movably installed with a thread on the upper end of the water outlet barrel 31, and the number of rotations of the barrel cover 33 changes the air intake between it and the water outlet barrel 31, thereby changing the amount of water dripping from the water outlet pipe 32 into the box body 1 ; The bucket cover 33 is provided with an inclined rod 34 that rotates along it. When the height of the bucket cover 33 changes, the position of the inclined rod 34 relative to the bucket cover 33 remains unchanged; the other end of the inclined rod 34 moves on the water outlet bucket 31, and the change in the position of the lower end of the inclined rod 34 marks the number of rotations of the bucket cover 33; the water storage bucket 4 is installed in the box body 1 through the bracket group 7, and water storage buckets 4 of different specifications are installed on the bracket group 7 to change the amount of watering for beans at one time; a seedling tray 5 with an aquifer is movably installed in the box body 1, and the aquifer can ensure moisture while allowing excess water to leak into the water receiving bucket 6; a support rod 9 is provided in the box body 1, and a button 10 is provided on one side of the support rod 9. A timer 8 is provided on the outside of the box body 1, and the button 10 is connected to the timer 8, and the water storage bucket 4 is in contact with the timer 8.

[0030] like Figure 1 As shown, one side of the upper end of the water storage barrel 4 is provided with an arc cover 42, and the arc cover 42 is provided with evenly distributed small holes. The setting of the arc cover 42 does not affect the water collection, and the small holes thereon can evenly spread water on the seedling tray 5.

[0031] like Figure 1As shown, a guide rail 12 is installed in the middle of the box body 1, and the guide rail 12 is used to install the seedling tray 5; sliders 13 are provided on both sides of the seedling tray 5, and the sliders 13 can move along the guide rails 12 for easy installation. In addition to the above structure, a placement groove is provided on the back of the box body 1, and the rear part of the seedling tray 5 is plugged into the placement groove, which is used in conjunction with the sliders 13 and the guide rails 12 to fix the seedling tray 5.

[0032] like Figure 2 As shown, the bracket group 7 includes a cross bar 71, an insert 72, an internal threaded sleeve 73 and a screw 74; the insert 72 and the internal threaded sleeve 73 are installed on the back of the box body 1, and the insert 72 is used to install the water bucket 4; the front end of the internal threaded sleeve 73 is threadedly installed with a screw 74, and the front end bearing of the screw 74 is installed on the cross bar 71, and the same insert 72 is installed on the cross bar 71. The water bucket 4 is provided with a slot 41 that is plugged into and cooperates with the insert 72.

[0033] like Figure 5 and Figure 6 As shown, the barrel cover 33 is provided with a bearing mounting ring 11, and an inclined rod 34 is hingedly mounted on the ring 11; a strip groove 16 is provided on one side of the top surface of the water outlet barrel 31, and the lower end of the inclined rod 34 is located in the strip groove 16 and moves along it, and a mark is provided on one side of the strip groove 16.

[0034] like Figure 8 As shown, the seedling tray 5 is provided with a partition 14 made of a light-transmitting material. Guide holes 15 are provided in the partition 14, with the lower diameter of the guide holes 15 being smaller than the upper diameter. Beans tend to become entangled with each other during growth, and their growth posture tends to tilt. Therefore, the partition 14 separates the beans, providing ample growing space and preventing excessive entanglement after seedling growth, which would hinder measurement. Furthermore, the guide holes 15 constrain the growth posture of the beans, preventing them from growing at an angle, which would hinder measurement.

[0035] Before use, the user opens the box door 2 and directly fills water into the water bucket 4 through the measuring cup; when the water level in the water bucket 4 rises, the center of gravity of the water bucket 4 also rises. When the center of gravity of the water bucket 4 exceeds the center of the bracket group 7, the water bucket 4 can be turned over to pour water onto the seedling tray 5; at this time, the user calculates the watering amount of the water bucket 4 at one time through the remaining water in the measuring cup, and records it; water buckets 4 of different specifications are measured in turn to obtain their corresponding watering amounts at one time, and record them so that a suitable water bucket 4 can be selected when the watering amount is changed later.

[0036] When in use, the user places the prepared beans evenly on the seedling tray 5 and installs the seedling tray 5 into the box body 1; the user rotates the bucket cover 33 on the water outlet bucket 31 to allow external air to enter the water outlet bucket 31; the movement of the bucket cover 33 causes the upper end of the inclined rod 34 to move upward, and the other end of the inclined rod 34 is located in the strip groove 16, and the strip groove 16 limits the movement of the inclined rod 34; and the mark corresponding to the lower end of the inclined rod 34 is the number of rotations of the bucket cover 33, which the user records; the position of the bucket cover 33 changes the amount of air intake and the amount of water outflow in the water outlet pipe 32, that is, different positions of the bucket cover 33 correspond to different watering time intervals of the water storage bucket 4; therefore, the air pressure in the water outlet bucket 31 changes, causing the water inside it to pass through the water outlet pipe 32 The water is dripped into the water storage barrel 4; continuous dripping causes the center of gravity of the water storage barrel 4 to change. When the center of gravity of the water storage barrel 4 exceeds the center of the bracket group 7, the water storage barrel 4 flips over and pours the water inside onto the seedling tray 5. The water storage layer on the seedling tray 5 absorbs water, so that the beans are in a moist growth state, and excess water drips from the seedling tray 5 into the water receiving bucket 6; when the water storage barrel 4 becomes empty, its center of gravity returns to its original position, that is, the water storage barrel 4 automatically rights itself under the action of its own weight and returns to its restored state; when the water storage barrel 4 is restored, one side of the water storage barrel 4 contacts the button 10. Each time the button 10 is touched, the timer 8 records the time, and the user can know the watering time interval; the device can realize automatic watering and automatic measurement of watering intervals, reducing the content of manual participation at night.

[0037] To adjust the watering amount, the user selects a new water storage barrel 4 and rotates the screw 74, which moves outward along the internally threaded sleeve 73, separating the cutting 72 from the slot 41. The crossbar 71 then rotates around the screw 74, fully revealing the water storage barrel 1. The user then removes the old water storage barrel 4 and installs the new one, varying the watering amount and observing the sprouting progress of the beans to determine the optimal watering amount. To change the watering interval, the user rotates the barrel lid 33, changing the amount of water flowing through the outlet pipe 32 and, in turn, the time it takes for the water storage barrel 4 to be watered after it is filled. By repeatedly varying the watering amount and watering time and observing the growth of the beans, the user can determine the optimal watering interval. Once the beans have finished sprouting, the user opens the door 2 and pulls the seedling tray 5 outward, causing the slider 13 to move within the guide rail 12. The tray can then be removed and the bean seedling growth can be measured.

[0038] Example 2

[0039] like Figure 4As shown, the bracket group 7 includes a cross bar 71, an insertion strip 72, a sleeve 75, a pull rod 76 and a spring 77. The insertion strip 72 and the sleeve 75 are installed on the back of the box body 1. A pull rod 76 is provided in the sleeve 75, and the pull rod 76 moves along the sleeve 75; the pull rod 76 is connected to the sleeve 75 by a spring 77, and the spring 77 resets the pull rod 76; a cross bar 71 is installed at the front end of the pull rod 76, and the same insertion strip 72 is installed on the cross bar 71, and a slot 41 is provided on the water storage barrel 4 to plug into the insertion strip 72.

[0040] When the watering amount needs to be adjusted, the user selects a new water storage barrel 4, moves the pull rod 76 outward along the sleeve 75, so that the insert 72 is separated from the slot 41; then the cross bar 71 is rotated around the pull rod 76 to fully display the water storage barrel 1 in front of the user. The user removes the old water storage barrel 4 and installs the new water storage barrel 4. Similarly, the components are returned to their original positions to change the watering amount.

[0041] Example 3

[0042] On the basis of Example 1 and Example 2, Figure 3 As shown, the insert 72 is fitted with a coil spring 78, the other end of which engages with the slot 41. One side of the slot 41 is provided with a recess, and one side of the coil spring 78 is provided with a corresponding ridge. During use, the insert 72 is installed between the water storage bucket 4 and the insert. After the water storage bucket 4 is filled with water, it becomes empty and needs to be reset. The weight of the coil spring and the coil spring ensure reliable reset, ensuring smooth operation.

[0043] Example 4

[0044] like Figure 8 As shown, the lid 33 is provided with an annular groove 18, within which is located a matching movable block 17 that moves along the groove. This movable block 17 is hingedly connected to a diagonal rod 34. A strip groove 16 is provided on one side of the top surface of the water outlet bucket 31, with the lower end of the diagonal rod 34 located within and moving along the groove. A marking is provided on one side of the strip groove 16. This structure allows the lid 33 to record the number of revolutions it has made, making it easy to record without affecting normal use.
