Description

TECHNICAL FIELD

[0001] The present application relates to a trencher capable of refining soil, belonging to the technical field of agricultural planting. In particular, it relates to a trencher which pushes the broken soil during trenching through the trenching blade, stirs and breaks the broken soil with the broken soil rod, and blocks the broken soil with the soil throwing baffle to avoid the broken soil from splashing. BACKGROUND

[0002] At present, various particles with different sizes, shapes, compositions and properties in the soil can be divided into single particles and complex particles. Single particles and complex particles can be further bonded or aggregated by physical, chemical, biochemical and biological effects to form various aggregates and structures with different sizes, shapes and properties. Single particles, complex particles and structures constitute the solid phase part of the soil. The size, shape and distribution of soil particles and inter-particle pores have an important influence on the physical and chemical properties of the soil. In deep trench digging and planting, a continuous deep trench is usually formed by digging with a shovel, and then the soil is backfilled and planted. During the deep trench digging process, it is difficult to unify the depth of the deep trench because it is manually dug. The soil dug by the shovel will cause soil clumping, which will affect the size of the soil particles and inter-particle pores during backfilling and planting. The use of a shovel to dig a deep trench and then backfill and plant has low efficiency. A large excavator tends to damage the inter-particle space of the soil. In addition, many lands in the south are hilly areas and are terraced, which will affect the entry of the excavator. Although the existing small portable trencher has small size and is not limited by terrain like a large excavator and can save manpower and improve digging efficiency, it cannot control the throwing distance of the soil after digging and is difficult to further refine and crush the soil. In hilly areas, the design of directly using a rotating crushing blade to dig soil trenches in soil with broken soil can easily damage the rotating blade or the trenching blade due to stones in the soil, resulting in a high damage rate of the trencher.

[0003] Publication No. CN102787621B discloses a continuous trencher, which includes a driving sprocket, a left driven sprocket, a right driven sprocket, a plurality of digging buckets with a U-shaped cross section and a bucket tooth at one end, a lower support sleeve, and a digging wheel shaft. The above-mentioned invention mainly digs soil and cannot remove the dug soil from the working area in time while forming a trench. It is suitable for trenching on a construction site and is not suitable for deep trenching in soil planting.

[0004] Publication No. CN2384993 discloses a trenching machine, which is mainly characterized by being composed of a carrier, a trench depth control mechanism, a trenching mechanism and a discharging device. The trench depth control mechanism is composed of a tension rod, a hydraulic cylinder and a thrust rod. The trenching mechanism is composed of a driving sprocket, a driven sprocket, a chain plate and a bracket. The trenching mechanism is connected with the carrier through the tension rod and the thrust rod. Although the above-mentioned invention can trench the soil, it is difficult to finely crush the soil, and the throwing distance of the soil cannot be controlled, which is not conducive to the planting of subsequent crops.
