A V-shaped underground channel deep loosening forming machine

Abstract

This invention relates to agricultural machinery and tillage methods, and more particularly to a V-shaped underground deep tillage shaping machine. It includes a front mounting assembly, a rear mounting assembly, a V-shaped deep tillage mounting assembly, and side assemblies. The side assemblies include clamps, two clamps arranged vertically and clamping the rear mounting assembly on both sides. A screw passes through the two clamps, and nuts are threaded onto both ends of the screw. The deep tillage utilizes shallow underground circular perforated drainage outlets to reduce salt accumulation in farmland, draining excess water through these outlets while retaining soil nutrients. The circular perforated drainage outlets lower the water level, promoting the downward transport of salt through soil drainage outlets, preventing salt accumulation at the soil surface during crop cultivation. This reliably removes salt, improves field drainage performance in relatively shallow soil layers, lowers the groundwater level, improves soil aeration, and is beneficial to crop growth.

Description

Technical Field

[0001] This invention relates to agricultural machinery and tillage methods, and more particularly to a V-shaped underground channel deep loosening and shaping machine. Background Technology

[0002] my country has a large area of ​​arable land and complex terrain. The soil in the Sanjiang Plain of Heilongjiang Province is greatly affected by the natural environment and is prone to flooding, especially in low-lying areas of arable land. Even a slight increase in rainfall can cause waterlogging, making field operations impossible. Later, open drainage ditches were adopted to drain the water from the fields. However, in low-lying areas or areas far from the edge of the fields, drainage problems are difficult to solve, resulting in serious losses to agricultural production.

[0003] The purpose of deep tillage is to loosen the soil, break up the plow pan, increase the rate and amount of rainwater infiltration, and reduce water loss through evaporation. After deep tillage, the loosened soil falls into the created V-shaped trenches, preventing the formation of vertical grooves that easily lead to moisture loss. Furthermore, the continuous "underground channels" formed after deep tillage facilitate drainage in low-lying and saline-alkali lands. Albic soils, due to their poor soil structure and low water holding capacity, do not solidify during spring thawing and do not infiltrate during the summer rainy season. They are prone to waterlogging due to water retention in the upper layer and surface waterlogging due to water accumulation. Simultaneously, the upper soil layer experiences frequent alternations between dry and wet conditions, exhibiting significant drought during periods of low spring rainfall; a drought can occur after 12-13 days without rain. Therefore, the soil moisture condition is unstable, making it neither drought-resistant nor waterlogging-resistant.

[0004] Soil moisture is a crucial component of soil fertility and is closely related to agricultural production. Its properties and dynamics not only affect the coordinated changes in soil fertility factors such as air, heat, and nutrients, but also directly impact crop growth. Frequent droughts and floods, with large fluctuations in soil moisture, often lead to low crop yields and unstable total output, severely hindering agricultural development. Therefore, a V-shaped underground channel deep loosening and shaping machine was designed. Summary of the Invention

[0005] This invention provides a V-shaped underground deep tillage forming machine, which utilizes shallow underground circular perforated drainage outlets to reduce salt accumulation in farmland, drains excess water through the circular perforated drainage outlets, retains soil nutrients, lowers the water level through the circular perforated drainage outlets, promotes the downward transport of salt through the soil drainage outlets, prevents salt from accumulating at the cultivated land level during crop planting, thereby reliably removing salt, improving the field drainage performance of relatively shallow soil layers, lowering the groundwater level, improving soil aeration, and benefiting crop growth.

A screw 4.8 passes through the two clamps 4.9, and both ends of the screw 4.8 are threaded with nuts.

[0032] The two clamps 4.9 can be used to clamp the two sides of the rear mounting assembly 2 of the frame, and then the two nuts on the screw 4.8 can be turned to press them onto the rear mounting assembly 2 of the frame. Then, the side assembly 4 can be connected to the two sides of the rear mounting assembly 2 of the frame as needed.

[0033] The front mounting assembly 1 of the frame includes a front frame weld 1.1, a bracket weld 1.2, a lever wheel assembly 1.3, a lever wheel mounting seat 1.4, and a frame pin 1.5. One end of the lever wheel assembly 1.3 passes through the lever wheel mounting seat 1.4, and the lever wheel assembly 1.3 and the lever wheel mounting seat 1.4 are connected by bolts. The lever wheel mounting seat 1.4 and the front frame weld 1.1 are connected by a clamping plate and fixed with bolts. One end of the bracket weld 1.2 passes through the front frame weld 1.1, and the bracket weld 1.2 and the front frame weld 1.1 are connected by bolts. The frame pin 1.5 is connected to the suspension point of the front frame weld 1.1 and fixed with a cotter pin.

[0034] The lever wheel assembly 1.3 includes a lever wheel bearing housing 1.3.1, a lever wheel 1.3.2, a lever wheel shaft 1.3.3, a dust cover 1.3.4, and a lever wheel mounting bracket welded together 1.3.5. Bearings are first installed on both sides of the lever wheel bearing housing 1.3.1, followed by mounting clips to prevent the bearings from falling out. Then, the lever wheel shaft 1.3.3 is inserted. The lever wheel shaft 1.3.3 and the lever wheel mounting bracket welded together 1.3.5 are connected at the lower end hole and secured with a nut. The other symmetrical component is assembled using the same method. This completes the installation of the lever wheel assembly.

[0035] The rear mounting assembly 2 includes a rear frame weld 2.1, a ground wheel assembly 2.2, a hydraulic cylinder 2.3, a hydraulic lock 2.4, and a hydraulic cylinder connecting sleeve 2.5. The rear mounting assembly 2 is connected to the front mounting assembly 1 via a hydraulic cylinder. The hydraulic cylinder 2.3 has frame pins 1.5 and hydraulic cylinder connecting sleeves 2.5 on both sides, which are fixed to the rear mounting assembly 2 and the front mounting assembly 1 respectively. They are connected by frame pins 1.5 and fixed with cotter pins. The ground wheel assembly 2.2 is connected to the rear frame weld 2.1 via a ground wheel bracket and fixed with bolts. The bracket weld 1.2 is fixedly connected to the rear frame weld 2.1 with bolts.

[0036] The V-shaped deep loosening installation assembly 3 includes a V-shaped deep loosening weld 3.1, a tapered column weld 3.2, and a polyethylene plastic wear-resistant plate 3.3. One end of the V-shaped deep loosening weld 3.1 is fixed to the rear frame weld 2.1 by bolts. The tapered column weld 3.2 is connected to the V-shaped deep loosening weld 3.1. The wear-resistant plate 3.3 is fixed to the V-shaped deep loosening weld 3.1 by bolts.

[0037] The present invention discloses a V-shaped underground ditch deep loosening forming machine. The soil penetration depth of the V-shaped deep loosening installation assembly 3 can be adjusted by adjusting the position of the V-shaped deep loosening hole distance connecting hole.

[0038] The two clamps 4.9 are each fixed with a boss 4.7 at their opposite ends. The two bosses 4.7 are respectively inserted into the two sides of the side seat 4.10. The vertical plate 4.1 is vertically slidably connected to the side seat 4.10. The side seat 4.10 is threaded with multiple fastening screws 4.11, which are all pressed onto the vertical plate 4.1.

[0039] Two protrusions 4.7 are inserted into the sides of the side seat 4.10, thereby connecting the side seat 4.10 between the two clamps 4.9. The vertical plate 4.1 can be inserted into the soil. Then, when the rear mounting assembly 2 of the frame moves, the V-shaped deep loosening mounting assembly 3 loosens the soil in the middle, and the vertical plate 4.1 loosens the soil on both sides, thereby improving the soil loosening effect.

[0040] The lower part of the vertical plate 4.1 is provided with an inclined part 4.2.

[0041] The inclined part 4.2 can extend the lower end of the vertical plate 4.1, thereby allowing the vertical plate 4.1 to extend into a deeper part of the soil.

[0042] A side cone block 4.3 is fixed to the lower part of the inclined portion 4.2.

[0043] Side cone 4.3 will move in the soil along with vertical plate 4.1. Side cone 4.3 will also make holes in the soil, leaving a water conduction opening to facilitate drainage.

[0044] The rear side of the vertical plate 4.1 is provided with multiple fixing rings 4.6 from top to bottom, and the front of the multiple side cone blocks 4.5 is provided with hanging rings 4.4, which are respectively hung on the multiple fixing rings 4.6.

[0045] When the vertical plate 4.1 moves within the soil, it pulls multiple hanging rings 4.4 and multiple side cones 4.5 to create holes at different heights in the soil, ensuring good air permeability at all soil heights.

[0046] Working principle:

[0047] The unit is powered by a wheeled tractor with a power output of 100-200 horsepower or more. The power take-off shaft operates at a speed of 100-120 r / min and provides hydraulic output after connection. The unit moves forward while simultaneously entering the soil. After the implement enters the soil, the operating speed is controlled between 3 and 4 km / h, and the operating depth is 400-600 cm.

[0048] During operation, the rear suspension point of the wheeled tractor is welded to the frame. The tractor's hydraulic output is adjusted according to the working depth, and the change in cylinder 2.3 is as follows: Figure 7 As shown. During use, hydraulic cylinder 2.3 is locked to prevent movement of the actuator after reaching the predetermined position. The V-shaped deep loosening assembly 3 penetrates deep into the ground, creating a soil-lifting effect. The bulldozer blade lifts the soil upwards, and the trapezoidal blade raises the soil by 120-140mm at a depth of approximately 50cm. The trapezoidal blade moves the soil clods above upwards by 120-140mm. A new hole is created at the conical column welded to the bottom of the trapezoidal blade 3.2, leaving a water conduction opening. Water flows out through the circular drainage hole formed by the V-shaped deep loosening assembly 3. The operational effect is as follows. Figure 8 As shown.

[0049] In summary, the V-shaped underground drainage deep loosening machine effectively solves the following problems: 1> Waterlogging due to stagnant water in the upper layer and surface waterlogging due to water accumulation; 2> Frequent alternation of wet and dry conditions in the upper soil layer, with significant drought during periods of low spring rainfall; 3> Slope collapse of drainage ditches, silt deposition, excessive weed growth, and high water levels in drainage ditches; 4> Low soil permeability and ineffective salt removal due to poor soil structure, spring thawing hardening, or other factors; 5> Rising groundwater levels due to excessive irrigation and leachate input; 6> Reduced discharge rate of underground drainage systems leading to rising groundwater levels.

[0050] Regarding these benefits: 1) Deep drainage loosens the soil structure, promotes soil microbial activity, allows crops to grow deeper and more vigorously, and ensures that the water level in the drainage ditch on one side of the site is lower than the water level at the outlet. 2) It reduces soil salinity; leaching removes more salt from the surface layer of shallow groundwater, but has no effect on the salinity of the lower soil layers. 3) It increases soil temperature. 4) It requires less earthwork than open channel excavation, improving land utilization and not hindering traffic or machinery operations. 5) It can also drain water during droughts, alleviating drought conditions, which is beneficial to crop growth, increases yield, and thus ensures food production.
