Soil screening equipment for agricultural seedling culture

Abstract

The invention relates to the field of agriculture, and particularly discloses soil screening equipment for agricultural seedling culture. The soil screening equipment for agricultural seedling culturecomprises a box body, a feed hopper, a discharging pipe, supporting legs and a discharge port; a horizontal screening cylinder is installed in the box body, the screening cylinder is of a round tablestructure, and a cleaning cylinder is coaxially fixed at the other end of the screening cylinder; a horizontal separation box is arranged at the inner bottom of the cleaning cylinder and comprises adischarging box and a shoveling box, and the discharging box is a hollow cylinder of a cuboid structure and is formed by welding stainless steel mesh plates; and the shoveling box is of a right-angletriangular prism structure. According to the soil screening equipment for agricultural seedling culture, screened large-particle soil, stones and the like are turned over through the arranged cleaningcylinder, the large-particle soil, the stones and the like are collected through the action of the separation box, and the large-particle soil, the stones and the like are taken out from the rotatingscreening cylinder in time, so that the operation can be carried out in the screening process, the cleaning is carried out without stopping, the soil screening is carried out continuously, and the rapid formation of agricultural seedling soil is facilitated.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to soil screening equipment for raising seedlings in agriculture. Background technique [0002] At present, the soil used for agricultural planting is easy to agglomerate after a long time, which reduces the air permeability of the roots. As if the roots are sealed up, the agglomerated soil needs to be crushed, so that the gaps between the soil particles are increased. Larger, the air can easily enter, increase the respiration of root cells, the respiration is strengthened, it can strengthen transpiration, and promote the exchange of mineral elements in the root hairs and soil, which can also promote the absorption of mineral elements by the roots; especially in the In the process of raising seedlings, the requirements for the soil are higher, and the requirements for the degree of refinement of the soil are more stringent, so that the soil can be fully mixed with other nutrients. After t...

[0003] Chinese patent (notification number: CN 207783460 U) discloses a kind of soil crushing and refining screening equipment for agricultural seedling raising, which is screened through the sieve plate and the sieve plate, and the soil with a large volume accumulates inside for a long time, which cannot Timely discharge leads to poor screening effect. In addition, the mesh cannot be cleaned during the screening process, making the screen easily blocked
