Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of vegetable planting equipment, specifically relating to a planting positioning device for standardized vegetable planting. Background Technology
[0002] Standardized vegetable cultivation, as an advanced agricultural production model, aims to significantly increase vegetable yield, optimize quality, and ensure food safety by implementing unified standardized processes to comprehensively regulate and manage all aspects of vegetable cultivation. In this process, precisely controlling the row and column spacing between vegetables is crucial for efficient use of land resources, rational conservation of water and fertilizer, and maximizing yield.
[0003] Currently, standardized planting practices often use furrows to separate vegetable plants in the same row. This not only facilitates daily management and harvesting by managers walking in the furrows, but also effectively improves ventilation and light penetration in the field. Row spacing is determined using straight poles as an auxiliary tool, with standard row spacing markings clearly marked on the poles. Managers must accurately dig planting holes on the furrows according to these markings, and then other personnel are responsible for planting the vegetables into the holes.
[0004] However, in greenhouse environments, due to space constraints, the length of the marking poles is usually limited. This means that managers need to frequently move the marking poles to complete the marking work for the entire field. This process, involving digging holes with a hoe and moving the marking poles, is not only monotonous and highly repetitive but also heavily reliant on manual labor, resulting in low efficiency. Therefore, a mechanized tool is needed that can precisely control row spacing and continuously dig planting holes. Utility Model Content
[0005] In order to overcome the problems existing in the background art, this utility model provides a planting positioning device for standardized vegetable planting.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a planting positioning device for standardized vegetable planting, comprising: a support plate, four legs arrayed at the bottom of the support plate, wheels at the bottom of the legs, a through hole in the center of the support plate, a support platform above the support plate and connected by a support column, an electric push rod on the support platform, a servo motor on the piston rod of the electric push rod, a spiral drill bit on the output shaft of the servo motor, and a measuring device for measuring the travel distance of the wheels; the piston rod passes downward through the support platform, and the spiral drill bit can pass through the through hole.
[0007] Preferably, the measuring device includes: a disc connected to the wheel and rotating synchronously with the wheel; magnetic poles disposed on the disc; a Hall effect wheel speed sensor disposed on the outrigger to sense the magnetic poles; an STM32 microcontroller electrically connected to the Hall effect wheel speed sensor; and a digital display module electrically connected to the STM32 microcontroller.
[0008] Preferably, both the electric actuator and the servo motor are electrically connected to the STM32 microcontroller, and the STM32 microcontroller is equipped with a control panel.
[0009] The beneficial effects of this utility model compared with the prior art are as follows:
[0010] This invention uses a Hall effect wheel speed sensor to accurately measure the number of wheel rotations, thereby determining the travel distance of the planting positioning device used for standardized vegetable planting, which is then displayed on a digital display module. After a certain distance, the administrator starts the servo motor to drive the auger drill bit to rotate, and the electric push rod drives the auger drill bit downward to drill out the planting hole. Then, the electric push rod lifts the auger drill bit upward, pushing the planting positioning device to the next planting hole digging position. Attached Figure Description

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below to facilitate understanding by those skilled in the art.
[0015] Please see Figures 1 to 2This utility model provides a planting positioning device for standardized vegetable cultivation, comprising: a support plate 1, four support legs 2 arrayed at the bottom of the support plate 1, wheels 3 at the bottom of the support legs 2, a through hole 4 in the center of the support plate 1, a support platform 6 above the support plate 1 and connected by a support column 5, an electric push rod 7 on the support platform 6, a servo motor 9 on the piston rod 8 of the electric push rod 7, a spiral drill bit 10 on the output shaft of the servo motor 9, and a measuring device for measuring the travel distance of the wheels 3; the piston rod 8 passes downward through the support platform 6, and the spiral drill bit 10 can pass through the through hole 4. The wheels 3 travel in the ditches on both sides of the field ridge, and the measuring device detects the forward distance of the planting positioning device. Based on the forward distance, the electric push rod 7, the servo motor 9, and the spiral drill bit 10 are used to drill planting holes on the field ridge. The servo motor 9 is equipped with a reducer.
[0016] The measuring device includes: a disc 11 connected to and rotating synchronously with the wheel 3; magnetic poles 12 disposed on the disc 11; a Hall effect wheel speed sensor 13 disposed on the support leg 2 to sense the magnetic poles 12; an STM32 microcontroller 14 electrically connected to the Hall effect wheel speed sensor 13; and a digital display module electrically connected to the STM32 microcontroller 14. The Hall effect wheel speed sensor 13 is existing technology, utilizing a Hall element to convert magnetic signals into electrical signals. When the magnetic poles 12 on the disc 11 pass the Hall element, they change the surrounding magnetic field, thereby generating an electrical signal. This electrical signal is converted into a digital signal by the STM32 microcontroller 14 and displayed on the digital display module. In this embodiment, the diameter of wheel 3 is measured beforehand. The disc 11 rotates synchronously with wheel 3. Therefore, the magnetic pole 12 on the disc 11 measures the number of revolutions of wheel 3. Multiplying the number of revolutions by the diameter gives the forward distance. After another calculation, the spacing of planting holes is determined after a certain number of revolutions. Each time the number on the digital display module increases by 1, it indicates that planting should be performed at that location. The planting spacing for different vegetables can be implemented by programming the STM32 microcontroller 14, which can be stored in different modes, allowing different vegetables to switch to the corresponding modes.
[0017] Both the electric actuator 7 and the servo motor 9 are electrically connected to the STM32 microcontroller 14, which is equipped with a control panel. The control panel allows control of the rotation / stop of the servo motor 9 and the extension / retraction of the electric actuator 7.
[0018] In this embodiment, the support plate 1 is provided with a handle for easy pushing of the planting positioning device.
[0019] When using the planting positioning device of this utility model for standardized vegetable cultivation:
[0020] Place the device in the prepared furrows, with the support plate 1 straddling the furrows. After connecting the power, push the device forward. In the initial position, use the control panel to drive the electric push rod 7 to drive the servo motor 9 downward. The servo motor 9 drives the auger drill bit 10 to drill out the planting hole. Then, the electric push rod 7 lifts the servo motor 9 and the auger drill bit 10, continuing to push the planting positioning device forward. The number on the digital display module increases by 1 to indicate that a planting hole has been drilled.
[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
