Description

Technical Field

[0001] The invention relates to the technical field of tea garden fertilization, and in particular to an all-in-one machine for loosening soil, digging trenches, fertilizing and covering soil in tea gardens. Background Art

[0002] Tea gardens are crucial bases for tea production, and soil management directly impacts the growth of tea trees and the quality of the tea. Traditional tea garden soil management primarily involves loosening the soil, trenching, fertilizing, and covering the soil. These processes typically rely on manual labor or single-function mechanical equipment, resulting in low efficiency, high labor intensity, and poor precision. In particular, controlling the loosening depth and fertilizer application rate is crucial for root development and nutrient absorption in tea trees, yet traditional equipment often struggles to achieve precise adjustments.

[0003] Most existing soil loosening equipment adopts a fixed-depth loosening method and cannot be dynamically adjusted according to the specific conditions of the tea garden soil, such as soil hardness and moisture, resulting in unsatisfactory loosening effects.

[0004] To sum up, how to solve the problem that most of the existing loosening equipment adopts a fixed depth loosening method and cannot be dynamically adjusted according to the specific conditions of the tea garden soil, such as soil hardness and humidity, resulting in unsatisfactory loosening effect has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an all-in-one machine for loosening soil, digging trenches, fertilizing and covering soil in tea gardens. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides an all-in-one machine for loosening soil, digging trenches, fertilizing and covering soil in tea gardens. The mechanical equipment can realize the integrated operations of loosening soil, digging trenches, fertilizing and covering soil, and has the function of adjustable loosening depth to adapt to different tea garden soil conditions and operation requirements.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a machine for loosening soil, digging trenches, fertilizing and covering soil in tea gardens, comprising a vehicle body and a controller, a handrail portion fixedly connected to the top of the rear end of the vehicle body in the direction of movement; a fertilizer box fixedly connected to the top of the vehicle body; a fertilizer pipe fixedly connected to the bottom of the vehicle body, the fertilizer pipe and the bottom of the fertilizer box are connected, an electromagnetic valve is connected in the fertilizer pipe, and the controller is used to control the operation of the electromagnetic valve; the fertilizer pipe is provided with a loosening assembly for loosening the soil, an adjustment assembly for adjusting the loosening depth of the loosening assembly and a trenching assembly for trenching the soil after loosening; a "V"-shaped bracket is fixedly connected to the side wall of the fertilizer pipe, and the bracket is provided with a covering assembly for covering the soil after trenching.

[0007] The technical principles of the above scheme are as follows:

[0008] The operator holds the handrail with both hands, and the controller starts the loosening component to drive the vehicle forward. During the forward movement of the vehicle, the loosening component dynamically adjusts the loosening depth through the adjustment component; the fertilizer in the fertilizer box is transported to the trenching component through the fertilizer pipe. The fertilizer pipe is equipped with a solenoid valve. The controller controls the opening and closing frequency and duration of the solenoid valve to adjust the amount of fertilizer; the trenching component can immediately perform trenching operations after loosening the soil to ensure that the fertilizer is evenly distributed in the trench; the covering component re-covers the soil after trenching; the blowing component can blow away the soil that may accumulate during the covering process to ensure uniformity of the covering.

[0009] The above scheme has the following beneficial effects:

[0010] 1. The present invention integrates multiple operation links such as loosening soil, ditching, fertilizing and covering soil into one device, realizing integrated operation, greatly improving the efficiency of tea garden soil management, reducing the time and labor cost required for switching multiple links in traditional operation methods, and reducing labor intensity.

[0011] 2. The present invention is equipped with an adjustment component to dynamically adjust the loosening depth, which can flexibly adjust the loosening depth according to the specific conditions of the soil hardness, humidity, etc. in different tea gardens, effectively improving the root development and nutrient absorption efficiency of tea trees.

[0012] 3. The soil covering assembly and the air blowing assembly equipped in the present invention cooperate with each other, which can not only cover the soil after trenching in time, but also blow away the soil accumulated during the soil covering process, thereby ensuring the uniformity of the soil covering.

[0013] Furthermore, the adjustment component includes a first support rod and a second support rod hinged on the side wall of the fertilizer pipe, a third support rod is hinged on the first support rod, a plurality of adjustment holes are opened on the second support rod, and the end of the third support rod away from the first support rod is hinged to the second support rod through the adjustment hole; the second support rod is fixedly connected to the end away from the fertilizer pipe with a drive plate, and a dual-output shaft reducer and a power box are fixedly connected to the drive plate; a driving member is fixedly connected to the top of the drive plate, and the output shaft of the driving member and the input shaft of the dual-output shaft reducer are coaxially fixedly connected, a first sprocket is coaxially fixedly connected to the output shaft at one end of the dual-output shaft reducer, and the output shaft at the other end of the dual-output shaft reducer passes through the side wall of the power box and extends into the power box and is coaxially fixedly connected to a wheel disc, and the wheel disc is provided with a blowing component for assisting soil covering.

[0014] Beneficial Effects: By changing the hinge position of the third support rod and the different adjustment holes on the second support rod, the shape of the triangular structure formed by the first, second, and third support rods can be changed, thereby adjusting the height of the loosening assembly and achieving flexible adjustment of the loosening depth. At the same time, the dual-output shaft reducer can provide power to the loosening assembly and the air blowing assembly respectively.

[0015] Furthermore, the loosening soil assembly includes a rotary tillage disc, which is rotatably engaged with the first support rod. A second sprocket is coaxially fixedly connected to the side wall of the rotary tillage disc. A chain is provided between the first sprocket and the second sprocket. A plurality of rotary tillage teeth are fixedly connected to the side wall of the rotary tillage disc along its circumference.

[0016] Beneficial effect: The driving member drives the first sprocket and the second sprocket to rotate, driving the rotary tillage disc and the rotary tillage teeth to rotate, which can drive the vehicle body forward. At the same time, the rotation of the rotary tillage teeth can efficiently break the soil and realize the loosening operation.

[0017] Furthermore, the furrowing assembly includes a triangular plow hook cover, which is sleeved on the bottom end of the fertilizing pipe.

[0018] Beneficial effect: The triangular plow hook cover design can open a groove in the soil after loosening, and it is connected to the bottom end of the fertilizer pipe, so that the fertilizer can fall directly into the opened groove during transportation, ensuring that the fertilizer is evenly distributed in the groove.

[0019] Furthermore, the soil covering assembly includes an L-shaped connecting rod that is symmetrical and fixedly connected to the bottom of the bracket. The L-shaped connecting rod is rotatably matched with a soil covering plate at one end away from the bracket. The soil covering plate is tilted and has a plurality of air holes on one side wall of the soil covering plate.

[0020] Beneficial effect: The symmetrically arranged covering plates can evenly cover the soil after trenching as the vehicle moves forward, ensuring comprehensive soil covering.

[0021] Furthermore, the air blowing assembly includes an electric air pump, which is fixedly connected to the bottom wall of the power box, and an input end of the electric air pump is connected to the outside of the power box.

[0022] The air holes are all connected to the output end of the electric air pump; and the controller is used to control the electric air pump to deliver air to the air holes.

[0023] Beneficial effects: The controller is used to control the operation of the electric air pump, so that the electric air pump can continuously and stably blow air into the air holes of the soil covering plate, blowing away the soil accumulated during the covering process and ensuring the uniformity of the soil covering. At the same time, blowing air into the soil can make the soil more fluffy and achieve a higher oxygen content in the soil.

[0024] Furthermore, a pressure sensor is fixedly connected to the bottom wall of the fertilizer box, and the controller is used to receive a weight signal of the fertilizer in the fertilizer box sent by the pressure sensor, and control the driving member to stop running based on the weight signal.

[0025] Beneficial effect: The pressure sensor can monitor the weight of fertilizer in the fertilizer box in real time. When the fertilizer weight reaches the set lower limit, the controller controls the drive component to stop running according to the received signal, avoiding continuing fertilization operations when there is insufficient fertilizer, and preventing missed fertilization or uneven fertilization.

[0026] Furthermore, each of the air holes is fixedly connected with a filter.

[0027] Beneficial effect: The filter can prevent soil particles and other impurities from entering the pores, avoid pore blockage, and ensure the blowing effect of the blowing component.

[0028] Furthermore, the height adjustment assembly includes a telescopic member that is symmetrically and fixedly connected to the bottom of the bracket, and the controller is used to control the extension and retraction of the output shaft of the telescopic member; the output shaft of the telescopic member is rotatably equipped with an auxiliary wheel.

[0029] Beneficial Effects: By controlling the extension and retraction of the telescopic output shaft through a controller, the height of the bracket and its connected covering assembly can be adjusted to suit covering operations in varying terrain conditions, ensuring effective covering. The auxiliary wheels provide support and guidance during movement, reducing the pressure on the ground. Together with the telescopic components, the overall height of the equipment can be flexibly adjusted, improving its maneuverability and adaptability, enabling stable operation in diverse tea garden environments.

[0030] Furthermore, a jog switch is fixedly connected to the top of the armrest, and the controller is used to receive a jog signal sent by the jog switch and control the extension and retraction of the output shaft of the telescopic member based on the jog signal.

[0031] Beneficial effects: The operator can conveniently and quickly control the extension and retraction of the telescopic output shaft through the inching switch. During the operation of the equipment, the operator can flexibly adjust the height of the equipment at any time according to the actual terrain conditions or operation requirements to achieve precise operation.

[0032] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is further described in detail through specific implementation methods:

[0038] Example 1:

[0039] As attached Figure 1-Figure 3 The figure shows: an all-in-one machine for loosening soil, trenching, fertilizing and covering soil in tea gardens, comprising a body 1 and a controller, wherein the top rear end of the body 1 in the direction of movement is fixedly connected to a handrail 2 by bolts; the top of the body 1 is fixedly connected to a fertilizer box 3 by bolts; the bottom of the body 1 is fixedly connected to a fertilizer pipe 4 by bolts, the fertilizer pipe 4 is connected to the bottom of the fertilizer box 3, and the fertilizer pipe 4 is connected to an electromagnetic valve in the fertilizer pipe 4, and the controller is used to control the operation of the electromagnetic valve; the fertilizer pipe 4 is provided with a loosening component for loosening the soil, an adjusting component for adjusting the loosening depth of the loosening component and a trenching component for trenching the soil after loosening; a "V"-shaped bracket 5 is fixedly connected to the side wall of the fertilizer pipe 4 by bolts, and the bracket 5 is provided with a covering component for covering the soil after trenching.

[0040] The adjusting assembly includes a first support rod 6 and a second support rod 7 hinged on the side wall of the fertilizer pipe 4, a third support rod 8 is hinged on the first support rod 6, and a plurality of adjusting holes are opened on the second support rod 7. The end of the third support rod 8 away from the first support rod 6 is hinged to the second support rod 7 through the adjusting hole; the end of the second support rod 7 away from the fertilizer pipe 4 is fixedly connected to a drive plate 9 by bolts, and the drive plate 9 is fixedly connected to a dual output shaft reducer 10 and a power box 13 by bolts; the top of the drive plate 9 is fixedly connected to a driving member by bolts, and the output shaft of the driving member and the input shaft of the dual output shaft reducer 10 are coaxially fixedly connected by bolts, and the output shaft at one end of the dual output shaft reducer 10 is coaxially fixedly connected with a first sprocket 11 by bolts, and the output shaft at the other end of the dual output shaft reducer 10 passes through the side wall of the power box 13 and extends into the power box 13 and is coaxially fixed with a wheel disc 12 by screws, and the wheel disc 12 is provided with a blowing assembly for assisting soil covering.

[0041] The soil loosening assembly includes a rotary tillage disc 17, which is rotatably engaged with the first support rod 6. A second sprocket is coaxially fixedly connected to the side wall of the rotary tillage disc 17 by bolts. A chain 15 is sleeved between the first sprocket 11 and the second sprocket. A number of rotary tillage teeth 18 are fixedly connected to the side wall of the rotary tillage disc 17 along its circumference by bolts.

[0042] The furrowing assembly includes a triangular plow hook cover 19, which is sleeved on the bottom end of the fertilizing pipe 4.

[0043] The covering assembly includes a symmetrical L-shaped connecting rod 20 fixedly connected to the bottom of the bracket 5 by bolts. The end of the L-shaped connecting rod away from the bracket 5 is rotatably matched with a covering plate 21. The covering plate 21 is set at an angle, and a number of air holes 22 are opened on one side wall of the covering plate 21.

[0044] The air blowing assembly includes an electric air pump, which is fixedly connected to the inner bottom wall of the power box 13 by bolts, and the input end of the electric air pump is connected to the outside of the power box 13.

[0045] The air holes 22 are all connected to the output end of the electric air pump; the controller is used to control the electric air pump to deliver air to the air holes 22.

[0046] A pressure sensor is fixedly connected to the bottom wall of the fertilizer box 3 by screws. The controller is used to receive a weight signal of the fertilizer in the fertilizer box 3 sent by the pressure sensor, and control the driving component to stop running based on the weight signal.

[0047] The height adjustment assembly includes a telescopic member 16 that is symmetrical and fixedly connected to the bottom of the bracket 5 by bolts. The controller is used to control the extension and retraction of the output shaft of the telescopic member 16; the output shaft of the telescopic member 16 is rotatably equipped with an auxiliary wheel 14.

[0048] A jog switch is fixedly connected to the top of the armrest portion 2 by screws, and the controller is used to receive a jog signal sent by the jog switch and control the extension and retraction of the output shaft of the telescopic member 16 based on the jog signal.

[0049] The specific implementation process is as follows:

[0050] To start the machine, the operator grasps the handrail 2 with both hands and activates the driver, which in this embodiment is a DC motor, via the controller. This drives the dual-output shaft reduction gearbox 10. The output shaft at one end of the dual-output shaft reduction gearbox 10 rotates the first sprocket 11, which in turn rotates the second sprocket via the chain 15, thereby rotating the tilling disc 17 and the tilling teeth 18, loosening the soil. Simultaneously, the controller sends a control signal to the electric air pump, which delivers air to the air holes 22, ensuring a continuous flow of air.

[0051] During the loosening process, the operator can adjust the adjustment assembly according to the actual soil conditions. By changing the hinge position of the different adjustment holes on the third support rod 8 and the second support rod 7, the triangular structure formed by the first support rod 6, the second support rod 7 and the third support rod 8 is changed, thereby flexibly adjusting the height of the loosening assembly and realizing dynamic adjustment of the loosening depth to adapt to different soil hardness and moisture conditions.

[0052] After scarification, the fertilizer in the fertilizer bin 3 is gravity-fed through the fertilizer pipe 4 to the trenching assembly. A controller controls the frequency and duration of the solenoid valve in the fertilizer pipe 4, precisely adjusting the amount of fertilizer applied, based on operational needs. The triangular plow hook cover 19 creates a groove in the scarified soil, ensuring that the fertilizer falls evenly into the groove.

[0053] As the machine continues to move forward, the covering plate 21, symmetrically positioned at the bottom of the support 5, begins to operate. As the vehicle 1 advances, the covering plate 21 evenly covers the excavated soil. During this process, air holes 22 on the covering plate 21 continuously blow air, dispersing accumulated soil during the covering process, ensuring uniformity, making the soil more fluffy, and increasing its oxygen content.

[0054] When the weight of the fertilizer in the fertilizer box 3 reaches the lower limit value set by the pressure sensor, the pressure sensor transmits a signal to the controller. After receiving the signal, the controller controls the drive component to stop running to avoid continued fertilization when there is insufficient fertilizer, resulting in missed fertilization or uneven fertilization.

[0055] If the terrain changes while the equipment is moving, the operator can use the inching switch on the top of the armrest 2 to send an inching signal to the controller. Based on this signal, the controller controls the extension and retraction of the output shaft of the telescopic member 16, adjusting the height of the bracket 5 and the connected soil covering assembly. Auxiliary wheels 14 provide support and guidance during movement, working with the telescopic member 16 to flexibly adjust the overall height of the equipment, ensuring stable operation in various tea garden environments and ensuring effective soil covering.

[0056] Example 2:

[0057] As attached Figure 1 As shown, the difference from embodiment 1 is that a filter is fixedly connected to each of the air holes 22 by screws.

[0058] The specific implementation process is as follows:

[0059] The filter can prevent soil particles and other impurities from entering the air holes 22, thereby preventing the air holes 22 from being blocked and ensuring the blowing effect of the blowing assembly.

[0060] Example 3:

[0061] As attached Figure 2As shown, the difference from Example 2 is that this embodiment also provides a protective component for separating tea bush branches during the forward movement of the tea garden soil loosening, trenching, fertilizing and covering machine.

[0062] The protection assembly includes a V-shaped baffle 23 fixedly connected to the end of the second support rod 7 away from the driving plate by bolts. The bottom of the baffle 23 is slightly higher than the bottom height of the tea bush from the ground, and the top height is slightly lower than the average height of the tea bush.

[0063] As the all-in-one machine advances through the tea garden, baffle 23 first contacts the tea bush branches. As the vehicle body 1 continues to advance, baffle 23, utilizing its unique shape, separates the tea bush branches to the sides, freeing space for subsequent operations such as loosening the soil, trenching, fertilizing, and covering the soil. Operators can flexibly adjust the tilt angle of baffle 23 based on the actual tea bush growth conditions, such as its density and height. For example, in areas with dense tea bushes, the tilt angle of baffle 23 can be appropriately increased to enhance its separation effect; in areas with sparser tea bushes, the tilt angle can be reduced to minimize unnecessary interference with the branches. This allows the all-in-one machine to efficiently and stably complete various tasks throughout the tea garden while minimizing any impact on tea bush growth.

[0064] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
