Description

Technical Field

[0001] The utility model relates to the technical field related to regular watering of seedlings, in particular to a regular watering device for seedling cultivation. Background Art

[0002] Seedling cultivation refers to the process of growing seedlings in a nursery, hotbed or greenhouse in preparation for transplanting them into the land for planting. Seedling cultivation is a labor-intensive, time-consuming and highly technical job.

[0003] The utility model with patent number CN216567359U discloses a water-saving regular water supply equipment for grain seedlings. The servo motor, threaded rod, support plate, water tank, water pipe, and support rod are arranged. Since the servo motor can drive the threaded rod to drive the support to move linearly, the water tank on the support plate can spray water into the seedling barrel through the water pipe, and the water tank can move linearly, so that the water tank can irrigate multiple seedling barrels with water, and since the speed of the servo motor is constant, the water tank moves at a uniform speed, so that the time interval for the water tank to irrigate the seedling barrel is fixed, which is convenient for the water tank to regularly supply water to the seedling barrel. When the above scheme is implemented, only simple timing processing can be performed, and more accurate irrigation cannot be performed according to the amount of soil moisture. Therefore, a regular irrigation device for seedlings is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a periodic irrigation device for seedling cultivation, which has the advantages of regular irrigation and can achieve more precise irrigation according to the amount of soil moisture, solving the technical problem that the amount of regular irrigation cannot be adjusted in time when there is excess moisture in the soil due to external factors such as the environment.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A regular watering device for raising seedlings comprises a fixed frame, a culture frame is arranged inside the fixed frame, a driving motor is arranged outside the fixed frame, a soil moisture detector is arranged at the bottom of the culture frame, a gear set is connected to the driving motor, the gear set drives a telescopic set to move forward and backward through a connecting piece, the telescopic set penetrates the side wall of the fixed frame and enters the interior thereof, an electromagnetic valve is arranged on the telescopic set, a water storage tank is arranged above the fixed frame, a display control screen is installed on the front outer wall of the water storage tank, a water pipe is arranged at the bottom and is inserted into the telescopic set through the fixed frame, the display control screen is electrically connected to the output end of the soil moisture detector, and the output end of the display control screen is electrically connected to the electromagnetic valve and the driving motor.

The telescopic set includes a telescopic rod a and a telescopic rod b, and the telescopic rod a is connected to the telescopic rod b through a bearing and is fixedly connected to the planetary gear.

[0008] Furthermore, a drain port is provided on the outer side of the culture rack, and a water inlet is provided on the top of the water storage tank.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] 1. The regular watering device for seedlings measures the soil moisture content through a soil moisture detector. When the soil moisture content is lower than the set value, the display control screen controls the drive motor to operate and controls the solenoid valve to open, thereby achieving more accurate regular watering of the seedlings.

[0011] 2. The regular watering device for seedlings drives the gear set to rotate through a driving motor, and then drives the telescopic set to move forward and backward through transmission action, so as to achieve uniform watering of the seedlings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1-3In the present embodiment, a regular watering device for raising seedlings comprises a fixed frame 2, a culture frame 1 is arranged inside the fixed frame 2, a driving motor 6 is arranged outside, a soil moisture detector 15 is arranged at the bottom of the culture frame 1, a gear set is connected to the driving motor 6, the gear set drives the telescopic set to move forward and backward through a connecting piece, the telescopic set penetrates the side wall of the fixed frame 2 and enters the interior thereof, an electromagnetic valve 11 is arranged on the telescopic set, a water storage tank 3 is arranged above the fixed frame 2, a display control screen 5 is installed on the front outer wall of the water storage tank 3, a water guide pipe 12 is arranged at the bottom and is inserted into the telescopic set through the fixed frame 2, the display control screen 5 is electrically connected to the output end of the soil moisture detector 15, and the output end of the display control screen 5 is electrically connected to the electromagnetic valve 11 and the driving motor 6.

[0018] In the present application, the soil moisture detector 15 has a transmitting electrode with a metal probe and a receiving electrode with a sensor inserted into the soil, and the current is introduced into the soil through the transmitting electrode through the metal probe with a current source. The moisture content in the soil can be inferred by measuring the impedance when the current passes through the soil. At the same time, the output end of the soil moisture detector 15 is electrically connected to the display control screen 5, and the output end of the display control screen 5 is electrically connected to the electromagnetic valve 11 and the drive motor 6. When the moisture content measured by the soil moisture detector 15 is lower than the set value, the display control screen 5 controls the drive motor 6 to operate and controls the electromagnetic valve 11 to open. The detected soil moisture content can achieve more accurate regular watering of seedlings.

[0019] Furthermore, the gear set includes a sun gear 7, a planetary gear 8 and a ring gear 13. The sun gear 7 is fixedly connected to the drive motor 6. The sun gear 7 drives the planetary gear 8 to rotate around its center through gear transmission. The telescopic set includes a telescopic rod a9 and a telescopic rod b14. The telescopic rod a9 is connected to the telescopic rod b14 through bearings and is fixedly connected to the planetary gear 8.

[0020] In the present application, when the soil moisture detector 15 detects that the soil moisture content is lower than the set value, the display control screen 5 controls the drive motor 6 to operate and controls the solenoid valve 11 to open. At this time, the operation of the drive motor 6 drives the sun gear 7 to rotate. When the sun gear 7 rotates, the sun gear 7 drives the planetary gear 8 meshing with it to rotate. At the same time, since the planetary gear 8 is also meshed with the gear, the self-rotation of the planetary gear 8 will cause it to roll on the ring gear 13, thereby causing the ring gear 13 to rotate. The telescopic rod a9 is connected to the planetary gear 8 shaft and is fixedly connected to the telescopic rod b14. The drive motor 6 includes a support rod 10 and a collar 4, the collar 4 is fixed on the support rod 10, and the telescopic rod b14 passes through the through holes on the collar 4 and the fixed frame 2 and extends into the interior of the fixed frame 2. When the driving motor 6 drives the gear set to rotate, the gear set drives the telescopic rod b14 to move. Since the telescopic rod b14 is restricted by the ring 4, the driving rod b14 will drive the telescopic rod a9 to move forward and backward, thereby converting the rotational movement of the gear set into the forward and backward movement of the telescopic set, thereby achieving regular watering of the seedlings and uniform watering of the seedlings.

[0021] Furthermore, a drain port 101 is provided on the outside of the culture rack 1 , and a water inlet 301 is provided on the top of the water storage tank 3 .

[0022] In the present application, a drainage port 101 is provided on the side of the culture rack 1 to facilitate the discharge of excess water in the soil, and a water injection port 301 is provided on the top of the water tank 3 to facilitate the replenishment of water in the water tank 3.
