Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an adjustable soil-crushing device for agricultural planting. Background Technology

[0002] Agriculture is an industry that utilizes the growth and development patterns of plants and animals to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of agricultural labor are living plants and animals, and the products obtained are the plants and animals themselves. Agriculture is a basic industry that provides support for national economic construction and development. Existing agricultural soil-crushing devices cannot conveniently handle the impurities filtered after soil crushing. When crushing clumps of soil, a crusher is generally used to crush the soil, and then a filter screen is used to filter out the stones and impurities in the soil. However, the stones and impurities remain on the filter screen after soil filtration, which will cause the filter screen to become clogged. It is necessary to remove the filter screen from the crushing device and clean it manually, which is very inconvenient.

[0003] For example, CN202221243906.2 discloses "A Soil Crushing Device for Agricultural Planting". The second lead screw drives the support rod to move, thereby changing the position of the fixed-length support rod. This causes the filter seat to tilt to the baffle position in the machine body. The first lead screw drives the cleaning seat to move on the filter seat, so that the cleaning seat pushes the residual gravel and impurities on the filter screen from the recycling channel into the recycling box. There is no need to manually remove the filter screen for cleaning, making cleaning more convenient.

[0004] In agricultural soil shredding equipment, the speed of the shredder is often adjusted by using a motor to regulate the crushing rollers. However, when adjusting the motor's operating frequency, it is necessary to ensure that the shredder has been completely stopped. The hardness and moisture of the soil that the soil shredding equipment faces vary, making it cumbersome to adjust the speed using a motor, which also reduces the effectiveness of the soil shredding equipment.
