Description

Technical Field

[0001] The invention belongs to the technical field of soil improvement and restoration, and in particular relates to a split-type spray fertilizer applicator. Background Art

[0002] At present, the fruit industry has become an important part of China's agricultural and forestry planting. However, in the process of fruit planting and management, the soil in the orchards has become compacted due to the lack of deep plowing all year round, which has prevented the flow of water, air and heat in the soil, damaged the soil capillaries, reduced the nutrient transport capacity, and sharply reduced the soil organisms and organic matter, which has hindered the growth of the fruit tree roots. At the same time, the compacted soil is not conducive to the storage of natural precipitation and the absorption and utilization of fertilizers, resulting in the loss of water and fertilizers and the impoverishment of the soil.

[0003] The existing methods and machines for soil cultivation in orchards mainly include: manual digging, rotary tillage with micro-tillage machine, trenching and loosening, traditional shovel-type or drill rod cutting deep loosening machines, small excavators, etc. The main problems with these operation methods and machines are: manual digging has many problems such as high labor intensity, low operation efficiency, shallow soil turning depth, high operation cost and labor shortage; rotary tillage with micro-tillage machine has many problems such as shallow soil turning depth, destruction of surface soil structure and difficulty in machine control; trenching and loosening, traditional shovel-type deep loosening and drill rod cutting deep loosening have problems such as limited application range, large resistance to deep loosening caused by tree roots, machine tools causing root breakage and damage, and unclear deep loosening effect when used in orchard operations.

[0004] The patent with application number CN201921638564.2 discloses a split-type pneumatic deep loosening machine for forestry and fruit industry, which is composed of a mobile platform, a power source, a hydraulic pump, a deep loosening gun, a spray generator, a hydraulic hammer, a hydraulic cylinder, a slide rail, an air compressor, and a hydraulic oil tank. The mobile platform is the carrying platform and walking device of the whole machine. The power source is installed on the mobile platform. The hydraulic pump is directly connected to the output end of the power source to provide hydraulic power for the whole machine. The deep loosening gun is the part that enters the soil during operation, and its length is determined according to the operating depth. The burst generator instantly releases compressed air of a certain pressure and volume, which enters the soil through the deep loosening gun, generates shock waves and gas expansion to loosen the soil, and the hydraulic hammer generates high-frequency impact force through hydraulic pressure to quickly place the deep loosening gun into the soil at a certain depth. The hydraulic cylinder extends and retracts up and down along the slide rail, the cylinder sleeve of the hydraulic cylinder is fixed on the slide rail, and the piston rod of the hydraulic cylinder is fixedly connected to the slide frame of the slide rail, pushing the slide frame of the slide rail and the hydraulic hammer, the burst generator, and the deep loosening gun installed thereon to slide up and down together.

[0005] This solution adopts the air pressure deep loosening method, which solves the problems of traditional deep loosening operation methods and is suitable for deep loosening of perennial crops in forestry and fruit industry. However, the branches of fruit trees in some orchards are generally low, and even fruit farmers have to bend down to walk into the orchard, and the row spacing is narrow. When loosening the soil after the fruit trees hang branches, the use of this device may break the branches of the fruit trees, causing the fruit trees to fall to the ground, causing losses to fruit farmers. Summary of the invention

[0006] The invention provides a split-type spray fertilizer applicator, which can avoid the problem of breaking branches of fruit trees when loosening the soil in an orchard.

[0007] In order to achieve the above-mentioned purpose, the present scheme provides a split-type spraying fertilizer applicator, including a frame and a working mechanism installed on the frame, the working mechanism including a deep loosening gun and a spraying system, the deep loosening gun is provided with a channel for the spraying airflow to pass through, the deep loosening gun is provided with a spray hole, the lower end of the channel is connected to the spray hole, the upper end of the channel is connected to the spraying system, the spraying system is used to generate a spraying airflow and form a spraying through the deep loosening gun, the frame is tilted when moving, the height of the frame in the tilted state is less than the height in the upright state, and the frame is provided with a walking mechanism.

[0008] The principle of this solution is: the frame is tilted to lower the overall height of the device and pushed to the position where the soil needs to be loosened, then the frame is erected, the deep loosening gun is placed in the soil, so that the injection hole of the deep loosening gun is sealed with the soil, compressed air is generated through the explosion system and an explosion is formed in the soil through the deep loosening gun to achieve the purpose of loosening the soil, then the deep loosening gun is pulled out, and the frame is tilted and pushed to the next position where the soil needs to be loosened.

[0009] Beneficial effects of this program: 1. When the device is moved in the orchard, the frame is tilted to reduce the overall height of the device, so that even if the device is moved in an orchard with low branches, the branches will not be broken or the fruits will not be knocked off.

[0010] 2. This device loosens the soil by airflow explosion. It can achieve deep loosening of the soil without turning over the soil surface, reducing the loss of air and water. The loosening range can cover the entire area of ​​root growth, will not cause damage to the soil aggregate structure, and meet the root development requirements of crops.

[0011] Furthermore, a feed port is provided on the deep loosening gun, the feed port is connected to a material box through a hose, a discharge valve is provided at the feed port, and the feed port is connected to a channel.

[0012] Beneficial effect: After the deep tillage gun performs the first deep tillage blasting in the soil, the discharge valve is opened, and the material enters the channel of the deep tillage gun for temporary storage, and then the discharge valve is closed, and the deep tillage blasting is performed again. The compressed air enters the channel and drives the material to be sprayed through the injection hole, and then the material is deeply applied.

[0013] Furthermore, an airway is provided on the subsoil gun, a through hole is provided on the side wall of the subsoil gun, an airbag is provided in the through hole, the airbag is connected to the airway, the airway is connected to a first air intake pipe, and the first air intake pipe is connected to an inflation device.

[0014] Beneficial effect: After the subsoil gun blasts and loosens the soil for the first time, the material enters the subsoil gun and the air charging device introduces air into the first air inlet pipe, so that the air bag bulges out from the through hole to contact the soil around the subsoil gun or embeds into the soil gap around the subsoil gun. Then the material enters the subsoil gun for temporary storage, and the air charging device is turned off. The blasting tank blasts and loosens the soil again through the subsoil gun, and the compressed air sprays the material deeply. Because after the subsoil gun blasts and loosens the soil for the first time, the shock wave generated by the airflow will loosen the soil around the subsoil gun, and then there will be a gap between the subsoil gun and the surrounding soil. If the second blasting and loosening is directly performed, the airflow will carry the material out of the gap, resulting in a poor effect of deep application of the material. By using an air bag to contact or embed in the soil and then block the gap, the material can be prevented from being sprayed out of the gap and splashing onto the operator's body or face. Secondly, because the gap is blocked, the material can be sprayed farther in the soil. Moreover, when the airbag is inflated, the soil around the subsoil gun is pushed away from the subsoil gun by the airbag. When the loosening and fertilization is completed and the gas in the airbag is discharged, the airbag retracts into the through hole. The gap between the subsoil gun and the surrounding soil is larger than before the airbag is inflated. When the subsoil gun is pulled out, the friction force on the subsoil gun is smaller, and it is easier for the operator to pull out the gun. Moreover, when the airbag is inflated, it will be embedded in the soil around the subsoil gun. When the subsoil gun explodes for the second time, it will be subject to the recoil force of the shock wave. The airbag embedded in the soil can prevent the subsoil gun from being rushed out by the recoil force of the shock wave.

[0015] Furthermore, an exhaust valve is provided on the first air intake pipe.

[0016] Beneficial effect: After the second deep plowing, the exhaust valve can be opened to discharge the air in the airbag.

[0017] Furthermore, the working mechanism also includes a reciprocating vibrator that provides reciprocating vibration for the deep loosening gun. The reciprocating vibrator is movably connected to the deep loosening gun. A slide rail is fixed on the frame, a bracket is slidably provided on the slide rail, and the reciprocating vibrator is fixed on the bracket.

[0018] Beneficial effect: When the subsoil gun is entering and exiting the soil, the hammer cores of the subsoil gun and the air hammer move up and down through the slide rail.

[0019] The reciprocating vibrator generates high-frequency impact force, which quickly places the deep loosening gun into the soil at a certain depth.

[0020] Furthermore, the reciprocating vibrator is a hammer core of an air hammer, and a second air inlet duct is provided on the frame, and the second air inlet duct is used to provide compressed air to the hammer core of the air hammer.

[0021] Beneficial effect: Compressed gas is provided to the hammer core of the air hammer through an existing compressed gas supply device such as an air compressor, and the loosening head is inserted into the appropriate position in the soil by utilizing the continuous impact of the air hammer.

[0022] Furthermore, the explosion system includes an explosion tank, the air outlet of the explosion tank is connected to the upper end of the explosion channel through a hose, and the air inlet of the explosion tank is connected to a third air inlet pipe, and the third air inlet pipe is used to introduce compressed air.

[0023] Beneficial effects: After the compressed air enters the explosion tank, the explosion tank instantly releases a certain amount of compressed air with a certain pressure and volume, and enters the soil through the deep loosening gun, generating shock waves and gas expansion to loosen the soil, break up the agglomeration, and loosen the soil in a wider range. Furthermore, a first button is provided on the discharge valve of the material box, and the first button is used to control the inflation device.

[0024] Beneficial effect: when the operator opens the discharge valve, he / she will press and hold the first button at the same time, and then the inflation device will open, and then the operator's hand will leave the discharge valve. When the material is lowered, the operator will press and hold the first button again when closing the discharge valve, and then the inflation device will close and stop inflation.

[0025] Furthermore, a rotating shaft and a first gear are rotatably provided at the upper and lower ends of the frame respectively, the rotating shaft is coaxially fixedly connected with the second gear, the first gear and the second gear are connected by a chain, the bracket is fixed on the chain between the first gear and the second gear, and the other end of the rotating shaft is fixedly connected with a crank.

[0026] Beneficial effects: First, the deep tillage gun moves downward for deep tillage and deep application, and then the crank is turned to drive the chain to move upward, and then the chain drives the bracket to move upward, and then the bracket drives the deep tillage gun to move upward until it moves out of the ground, making it easier to move the device to the next work point.

[0027] Furthermore, a second button for controlling the exhaust valve is provided on the crank handle.

[0028] Beneficial effect: the operator presses the second button while holding the crank handle, thereby opening the exhaust valve, exhausting the gas in the airbag, and retracting the airbag into the channel; when the deep loosening gun is successfully pulled out, the operator stops shaking the crank handle and takes his hand off the crank handle, thereby the second button is not pressed, and the exhaust valve is closed.

[0046] As attached Figure 1-4 As shown, A split-type spray fertilizer applicator includes a frame 1 and a working mechanism 2 installed on the frame 1. The frame 1 is provided with a handle 25 and a running wheel 28. When an operator moves the frame 1, the handle 25 tilts the frame 1 and the running wheel 28 pushes the frame 1 forward. The running wheel 28 is a wheel hub motor tire. When the operator pushes the device to move, it is more labor-saving.

[0047] The frame 1 is provided with a start button for starting the wheel hub motor, and when the start button is pressed, the running wheel 28 moves forward.

The two auxiliary wheels can better control the balance of the device and prevent the device from tipping over.

[0048] The working mechanism 2 includes a deep loosening gun 3, a hammer core 13 of an air hammer, a bracket 12, an blasting tank 15 and a control system. The lower end of the deep loosening gun 3 is conical, and a channel 4 for the passage of blasting airflow is provided inside the deep loosening gun 3. The length of the deep loosening gun 3 is 20cm-100cm, and the hammer core 13 of the air hammer is movably connected to the deep loosening gun 3.

[0049] As attached Figure 5-6 As shown, A slideway is provided on the hammer core 13 of the air hammer, and the upper end of the deep loosening gun 3 slides in the slideway. A groove 31 is provided on the upper end of the deep loosening gun 3, and a limiting hole 32 is provided on the hammer core 13 of the air hammer. A pin matching the groove 31 is provided in the limiting hole 32 with an interference fit.

[0050] Insert the upper end of the subsoil gun 3 into the slideway, and then insert the latch into the stopper. Because the latch matches the groove 31, and the length of the groove 31 matches the vibration amplitude of the hammer core 13 of the air hammer, the maximum distance between the impact surface of the hammer core 13 of the air hammer and the impact surface of the subsoil gun 3 is limited by the latch. When the subsoil gun 3 needs to be replaced, the latch can be directly removed. The interference fit between the latch and the stopper hole 32 prevents the latch from falling off during frequent vibrations.

[0051] The hammer core 13 of the air hammer is fixed on the bracket 12, and the frame 1 is provided with a slide rail, and the bracket 12 is slidably arranged on the slide rail. When the subsoil gun 3 is carried out in and out of the earth, it moves up and down through the slide rail.

[0052] The vehicle also includes an air source system 22, which includes a vehicle frame 23, an air compressor 24 and an air storage tank 33. The air compressor 24 and the air storage tank 33 are located on the vehicle frame 23, and the air storage tank 33 is connected to the air compression device and the explosion tank 15 through pipelines.

[0053] The air storage tank 33 is used for compressed air buffering and storage, and its pressure and capacity match the exhaust pressure and exhaust volume of the air compressor 24. The explosion tank 15 instantly releases compressed air of a certain pressure and volume, which enters the soil through the deep loosening gun, generates shock waves and gas expansion to loosen the soil, break the plate agglomeration, and loosen the soil in a wider range.

[0054] The air compressor 24 provides compressed air to the hammer core 13 of the air hammer, and the deep loosening gun 3 is quickly placed into the soil at a depth of 20cm-100cm by utilizing the continuous impact of the air hammer.

The explosion tank 15 is provided with a pressure sensor for measuring the air pressure in the explosion tank 15, and the explosion tank 15 is provided with an air charging valve, which is used to open and close the third air inlet pipe 16. The air charging valve and the pressure sensor are both electrically connected to the control system. When the pressure in the explosion tank 15 reaches the set value, the pressure sensor feeds back the signal to the control system, and then the control system closes the air charging valve. When the pressure in the explosion tank 15 is less than the set value, the pressure sensor feeds back the signal to the control system, and the control system opens the air charging valve, and then the compressed air is passed into the explosion tank 15. The explosion tank 15 is also provided with an explosion valve, which is used to operate the air in the explosion tank 15 to form an explosion through the subsoil gun.

[0056] The frame 1 is provided with an explosion button 26 of the explosion can 15 and an air charging button 27 of the hammer core 13 of the air hammer.

[0057] When the explosion button 26 is pressed, the compressed gas in the explosion tank 15 is exploded through the deep loosening gun 3. When the inflation button 27 is pressed, the gas storage tank 33 inflates the hammer core 13 of the air hammer, so that the hammer core 13 of the air hammer impacts the deep loosening gun 3 downward. When the explosion button 26 and the inflation button 27 are released, the explosion tank 15 does not explode, and the gas storage tank 33 does not inflate the hammer core 13 of the air hammer.

[0058] A material box 7 is provided on the frame 1. Fertilizers, soil conditioners, soil improvers, microbial agents, clay powder, sand, water retaining agents, heat retaining agents or pesticides can be placed in the material box 7 according to the health of the soil. After the soil is loosened by spraying, the materials are spread into the soil to facilitate the materials to enter deep into the soil and improve the soil.

[0059] The subsoil gun 3 is also provided with a feed port 6, which is connected to a material box 7 through a hose, and a feed valve 8 is provided at the feed port 6, which is connected to the channel 4.

When the operator opens the discharge valve 8, he presses the first button at the same time, and the electric inflator is turned on. Then the operator's hand leaves the discharge valve 8. When the material is discharged, the operator closes the discharge valve 8 and presses the first button again, and the electric inflator is turned off and the inflation stops.

[0069] Then the operator presses the spray button 26 again to spray and deep loosen, and the compressed air enters the channel 4 to drive the material to be sprayed through the spray hole 5, thereby deeply applying the material. The operator holds the crank 21 and presses the second button, thereby the exhaust valve is opened, the gas in the airbag 10 is discharged, and the airbag 10 retracts into the channel 4.
