Description

Technical Field

[0001] The utility model relates to the technical field of soil improvement, and in particular to a device for soil repair and alkalinity reduction. Background Art

[0002] Alkaline soil generally refers to soil with a pH greater than 7, including saline soil, salinized soil, alkaline soil and alkaline soil. Planting plants in alkaline soil will cause physiological drought of the plants, damage plant tissues, affect the normal nutrient absorption of the plants, and affect the closure of the plants' stomata.

[0003] Salinization and alkalization often occur at the same time. For soil, the higher the degree of alkalinity, the worse the physical and chemical properties. It is easy to swell, muddy and disperse when wet, and shrink, hard and compacted when dry. The ventilation and water permeability are particularly poor. Alkaline soil will reduce the effectiveness of soil nutrients to varying degrees, making it difficult to form a good soil structure, severely inhibiting the activity of soil microorganisms and affecting the growth of various crops. Generally speaking, the purpose of improving saline-alkali soil is to improve the physical, chemical and biological properties of the soil to a certain extent.

[0004] During the research and development, the researchers found that spraying the neutralizing agent on the soil surface to allow the neutralizing agent to penetrate into the soil is a slow and time-consuming process for improving alkaline soil. In addition, the neutralizing agent is a chemical agent with a certain volatility. Spraying the neutralizing agent on the soil surface can easily lead to a waste of the neutralizing agent, and the volatilized chemicals can easily cause harm to the surrounding environment and organisms.

[0005] The existing application number is 201820520756.2, which is a soil improvement, loosening and spraying device. It includes a plate surface, on which a loosening device, a tilling device and a spraying device are respectively arranged from right to left. The loosening device includes a fixed plate, a hydraulic rod 1, a rack, a gear, a plurality of loosening knives, a cross bar 1, a cross bar 2 and a fixed rod. A rack and a gear are arranged in the fixed plate, and the end of the rack is connected to the cross bar 1. The ends of the loosening knives are all hinged on the cross bar 1. A cross bar 2 is arranged between the two fixed plates, and the middle part of each loosening knife is connected to the cross bar 2 through the fixed rod. The tilling device includes a drum, a plurality of tilling shovels, a rotating roller, a motor, a hydraulic rod 2, a hydraulic rod 3, and a tilling rake. A plurality of tilling shovels are axially arranged on the drum, and a tilling rake is arranged at the end of the hydraulic rod 3. The spraying device includes a liquid storage tank, a liquid transfer pipe and a plurality of nozzles. The beneficial effects of the utility model are: effectively improving the efficiency of tilling and loosening the soil when the tiller is working, improving the flatness of the soil, and being able to spray drugs in a timely and effective manner to remove pests.

[0006] However, the spraying range of the above device is small, and it is also inconvenient for a single person to operate. Summary of the invention

[0007] The technical problem to be solved by the utility model is to provide a device for soil remediation that occupies a small volume, is easy to operate by one person, has a large spraying range, and has high plowing efficiency so that the liquid medicine is evenly mixed to achieve efficient alkalinity reduction, in view of the deficiencies of the above-mentioned prior art.

[0008] In order to achieve the above-mentioned purpose, a device for soil remediation and alkalinity reduction includes a hand-held tractor body, the hand-held tractor body includes a front part and a rear part, a power component and a control handle are arranged at the front part, the power component synchronously drives a wheel and a plowing device, and is characterized in that: the plowing device includes a fan-shaped plow driven by the power component, a medicine tank frame hinged to the front part is arranged at the rear part, a soil turning piece is arranged at the hinged end of the medicine tank frame and the front part, a medicine tank is arranged on the medicine tank frame, and at least two blocking rods are arranged above the medicine tank to prevent the medicine tank from detaching, and the two blocking rods It is fixedly connected to the medicine tank frame, and a support plate is fixedly provided between the two baffle bars.

After the plowing device plows the soil, the medicine spraying device sprays the neutralized medicine solution and mixes it with the soil.

[0009] By adopting the above technical scheme, when the power component is working, the wheel and the plowing device are driven to rotate synchronously so that the plowing device can also perform the plowing operation synchronously when the wheel moves forward or backward. Since this product has a large vibration feeling, the barrier rod can be used to allow the medicine tank to be filled with sufficient medicine liquid while preventing the medicine tank from vibrating out due to the vibration of the walk-behind tractor. Stable spraying is achieved through the water pump, which can also be opened and closed by the valve, and the spraying range of the medicine liquid is increased by the double-headed medicine nozzle. At the same time, after the plowing device plows the soil, the medicine liquid and the soil can be fully mixed to prevent the medicine liquid from being unable to enter the soil due to soil compaction. The fan-blade plow has a higher soil turning efficiency and can also cooperate with the soil turning piece to turn the soil. The two ends of the double-headed medicine nozzle can be bent forward for storage, thereby reducing the overall volume of the product, and can also be straightened at both ends. The medicine nozzle is always facing downward, thereby achieving a large spraying range. The function of the support plate is to place components such as the water pump and to increase the overall strength of the medicine tank frame.

[0011] By adopting the above technical solution, the pipe clamp can be directly welded or fixed at the two end positions of the support plate by bolts. When the two ends of the double-headed liquid medicine nozzle are straightened, since the soft tube part is just located in the pipe clamp and the hard tube part is in contact with the first slot, it can maintain a straight state. When it needs to be stored, the double-headed liquid medicine nozzle is lifted up and then bent forward through the soft tube section, and the hard tube part is in contact with the second slot. Since the second slot is located at a vertical position of the first slot, the double-headed liquid medicine nozzle is also bent forward for storage.

[0012] A device for soil remediation and alkalinity reduction can be further configured as follows: a brake universal wheel is provided at one end of the bottom of the medicine tank frame away from the vehicle front.

[0013] By adopting the above technical solution, the entire walk-behind tractor can be positioned in one position for plowing and spraying operations through the brake universal wheel, and can also be turned to spray and plow the soil, making it more stable and having a better braking effect when combined with the handlebar.

[0014] A device for soil remediation and alkalinity reduction can be further configured as follows: the fan-blade shaped plow includes a plow shaft transmission-connected to a power component, the plow shaft is provided with at least three plow plates on each side of the power component, blades are provided at the four corners of the plow plates, and the wheels are provided at both ends of the plow shaft.

[0015] With the above technical solution, the plow shaft is equivalent to the transmission shaft, which drives the wheels and the moldboard at the same time. When the moldboard rotates, the blades on it also rotate continuously to turn the soil.

[0016] A device for soil remediation and alkalinity reduction can be further configured as follows: the blades are arranged in an arc shape toward the wheel direction or the power component direction, and the bending directions of adjacent blades are opposite.

[0017] By adopting the above technical solution, the blades are arranged in an arc shape, thereby making it easier to turn the soil. At the same time, the bending directions of adjacent blades are arranged in opposite directions in order to increase the contact area with the soil, making turning the soil more labor-saving.

[0018] A device for soil remediation and alkalinity reduction can be further configured as follows: the top of the soil-turning piece is bent toward a power component, a plurality of height adjustment grooves are axially arranged at one end of the soil-turning piece away from the top, and the medicine tank frame and the hinged end of the vehicle head are hinged to achieve height adjustment by being hinged to height adjustment grooves of different heights.

[0019] With the above technical solution, since the soil is hard, soft or has potholes, the turning depth of the soil turning piece also needs to be adjusted. When the bolt passes through the hinged end between the medicine tank frame and the front of the vehicle and passes through one of the higher height adjustment slots, the curved section at the top of the soil turning piece will extend further into the soil, thereby achieving the adaptation of the soil turning piece to different soil depths, making the entire product more adaptable.
