Description

Technical Field

[0001] This utility model relates to the technical field of Gastrodia elata planting equipment, specifically a soil covering and leveling device for Gastrodia elata planting. Background Technology

[0002] In the standardized cultivation of Gastrodia elata, layering soil in the planting holes is a crucial agronomic step. The traditional method involves first covering the soil with a layer of substrate, then spreading a moisture-retaining material (such as sawdust or fallen leaves), and finally covering it with another layer of substrate to secure the moisture layer. Currently, this process mainly relies on manual labor using simple tools such as shovels and rakes, which suffers from high labor intensity, low efficiency, and difficulty in precisely controlling the thickness and uniformity of the soil covering. This not only consumes a large amount of manpower but also directly affects the growth environment and final yield of Gastrodia elata.

[0003] Although there are some general-purpose soil covering and mulching machines in agricultural production, they can usually only complete the covering operation of a single material and a single thickness, and cannot adapt to the special requirements of the "substrate-moisturizing-substrate" sequence of multi-layered and heterogeneous materials unique to the cultivation of Gastrodia elata. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soil covering and leveling device for planting Gastrodia elata, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil covering and leveling device for planting Gastrodia elata, characterized in that it comprises: a walking support; three independent covering chambers arranged sequentially along the length of the walking support, respectively for containing substrate soil, moisture-retaining material, and substrate soil; four walking wheels distributed at the four corners of the bottom of the walking support; a rotary encoder connected to one of the walking wheels for detecting the walking speed and generating a speed signal; and three DC geared motors, respectively driving a feeding unit disposed at the bottom of each covering chamber to form a feeding port of the covering chamber. The system is connected to the rotary encoder and the DC geared motor and is configured to control the speed of the DC geared motor according to the speed signal.

[0006] Preferably, the bottom plate of the covering compartment is inclined, and the discharge port is provided at the lowest point of the bottom plate; the discharge port is an elongated slot extending along the width direction of the traveling support; the discharge unit is at least partially located at the discharge port.

[0007] Preferably, the feeding unit includes a rotating shaft and a scraping part; the rotating shaft is rotatably mounted via bearings, and its axial direction extends along the width direction of the traveling bracket; the scraping part includes at least two scrapers extending along the axial direction of the rotating shaft, and the scrapers are circumferentially and evenly fixed to the side wall of the rotating shaft; one end of the rotating shaft is drivenly connected to the DC geared motor to drive the scrapers to rotate and scrape the material in the covering chamber out from the feeding port.

[0008] Preferably, corresponding to the covering chamber for containing the moisturizing material, the scraping part consists of a plurality of circumferentially distributed spikes on the sidewall of the rotating shaft, the spikes being arranged in multiple rows along the axial direction of the rotating shaft.

[0009] Preferably, a vibrator acting on the bottom plate is provided below the bottom plate of the covered compartment.

[0010] Preferably, the front end of the traveling support is provided with a traction frame, which is used to connect to the traction point of an external towing vehicle.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. Traditional manual soil covering requires three separate steps. This device, with its three independently arranged covering chambers, can complete the entire soil covering process—from the bottom substrate soil to the intermediate moisture-retaining layer and finally the top substrate soil—continuously and precisely in a single pass. This combines multiple steps into one, reducing manual back-and-forth movement and significantly lowering labor intensity. Simultaneously, mechanical feeding ensures uniform material distribution across each layer, overcoming the problems of inconsistent soil thickness and easy mixing inherent in manual soil covering, and ensuring consistency in agronomic practices.

[0012] 2. To address the differences in physical properties (viscosity and looseness) between soil and moisture-retaining materials, this device employs a differentiated design for the feeding unit: For the soil chamber, a scraper-type shaft is used to forcefully and smoothly scrape and deliver sticky soil, preventing compaction and blockage; for the moisture-retaining material chamber, a toothed shaft is used to gently and effectively deliver loose materials, avoiding entanglement and bridging. Combined with the auxiliary arch-breaking effect of the bottom plate vibrator, this fundamentally ensures continuous, stable, and blockage-free feeding of different materials under various humidity conditions, guaranteeing the smoothness and reliability of operations.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1 to 4 This utility model provides a soil covering and leveling device for planting Gastrodia elata, including a walking support 1, a covering chamber 4 unit, a walking and traction unit, a material feeding and driving unit, a control system, and a leveling unit.

[0017] The traveling support 1 is a frame structure welded from rectangular steel pipes, providing a mounting base for all its components. A towing frame 2 is fixedly connected to the front end of the traveling support 1. The towing frame 2 is provided with standard mounting holes 3 for quick connection to the towing point of an external towing vehicle such as a tractor via a towing pin.

[0018] The covering chamber 4 unit comprises three independent covering chambers 4, arranged and fixed sequentially along the length of the traveling support 1 (i.e., the forward direction). From front to back, they are: the first covering chamber 4a, used to hold the bottom substrate soil; the second covering chamber 4b, used to hold the intermediate moisture-retaining material (such as sawdust, shavings, or chopped straw); and the third covering chamber 4c, used to hold the top substrate soil. The cross-section of each covering chamber 4 is an inverted trapezoid, wider at the top and narrower at the bottom, with its bottom plate 5 inclined at a angle of 15-30 degrees, lower at the front and higher at the back. At the lowest point of the front edge of the bottom plate 5, a through-type elongated discharge port 6 is opened along the width direction of the traveling support 1. In addition, an electric vibrator 7 is installed on the lower surface of the bottom plate 5 of each of the first and third covering chambers (4a, 4c) to periodically vibrate the bottom plate 5, effectively preventing moist soil from arching or sticking to the walls and clogging inside the chamber.

[0019] The walking and traction unit includes four walking wheels 8, which are mounted at the bottom of the walking support 1 in a four-corner arrangement via wheel frames 9. An incremental rotary encoder 10 is coaxially fixed on the axle of one of the walking wheels 8 for accurately detecting the rotational speed of the walking wheel 8.

[0020] The feeding and driving units are respectively arranged in the three covering chambers 4. Each covering chamber 4 has a feeding unit in its elongated feeding port 6. For the first and third covering chambers (4a, 4c), the feeding mechanism is a scraper 12 type feeding unit. This unit includes a rotating shaft 11 that is horizontally mounted on the traveling support 1 through a bearing seat and is parallel to the width direction. On the side wall of the rotating shaft 11, four flat scrapers 12 extending axially are evenly welded along the circumference. One end of the rotating shaft 11 is directly connected to the output shaft of a DC geared motor 14 through a coupling. When the motor starts, it drives the scraper 12 to rotate, scraping the substrate soil in the covering chamber 4 smoothly and forcibly out of the feeding port 6. For the second covering chamber 4b, the feeding unit is a nail tooth 13 type feeding unit. On the side wall of its rotating shaft 11, multiple rows of conical nail teeth 13 are matrix-welded along the axial and circumferential directions, which are also driven by a DC geared motor 14. The spike 13 effectively moves the fluffy moisturizing material, preventing fiber entanglement and ensuring its smooth and dispersed distribution.

[0021] The leveling unit (not shown in the figure) is suspended at the rear of the traveling support 1. It includes a leveling rake frame, which is hinged to the traveling support 1 via two adjustable-length rods, allowing for adjustment of its ground clearance. A row of elastic rake teeth is horizontally fixed to the lower part of the leveling rake frame. Behind the rake teeth, a freely rotatable lightweight compaction roller is also installed. This unit is towed as a whole, responsible for combing, initially leveling, and lightly compacting the three layers of material covered by the device.

[0022] The control system is the core of the device. It consists of three main parts: controller 15, drive unit, and power supply unit.

[0023] The system uses an embedded industrial controller 15 (such as a PLC or a high-performance microcontroller) as its core controller. The speed pulse signal collected in real time by the rotary encoder 10 is input to the input port of the controller 15. The controller 15 has three preset independent proportional-integral (PI) control algorithm modules, corresponding to three DC geared motors 14 for material feeding. Users can set the target soil cover thickness H through a human-machine interface (such as a touchscreen). The controller 15 calculates the real-time walking speed V based on the encoder signal and, according to the formula N=K*V*H (where N is the target motor speed and K is the feeding coefficient related to material characteristics), calculates and outputs three independent pulse width modulation (PWM) signals to the three motor drivers (such as DC brushed motor speed controllers). The motor drivers precisely control the speed and torque of the corresponding DC geared motors 14 according to the received PWM signal instructions. For the first and second covering chambers 4, the motors of their feeding units start synchronously under control; for the third covering chamber 4c, the motors of its feeding unit can be set to start later, so as to achieve staggered laying of the three layers of material in the longitudinal direction, forming clear stratification. The start and stop of the vibrator 7 can also be controlled by the controller 15 according to the working status of the feeding motor, or set to intermittent operation mode. The control system uses a large-capacity lithium iron phosphate battery pack 16 as the main power source, and needs to be calculated to meet the needs of all motors, vibrators 7 and controller 15 to work continuously for at least one shift (e.g., 4-6 hours). The battery pack 16 is installed in a dedicated sealed battery box on the traveling support and is waterproof and dustproof.

[0024] When using this utility model: Before operation, the corresponding materials are added to the three covering chambers 4, and the thickness parameters of each layer of soil covering are set through the controller 15. When the device is pulled forward by a tractor, the rotary encoder 10 detects the speed in real time. The controller 15 automatically and independently adjusts the speed of the three DC motors according to the speed and the set thickness, so that the first, second, and third covering chambers (4a, 4b, 4c) are sequentially and quantitatively fed. While feeding, the vibrator 7 works intermittently to prevent blockage. After the three layers of material are sequentially covered in the planting furrow, the leveling unit at the rear then combs and rakes the soil covering layer, and the press roller completes the final light compaction and shaping, forming a flat planting bed that meets agronomic requirements in one go.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
