Problems solved by technology

[0003] Traditionally, the operation of sieving soil is mainly done manually, which is very laborious and only suitable for sieving a small amount of soil. In the case of many requirements, manual screening is not only labor-intensive, but also low-efficiency, time-consuming and labor-intensive, and will not meet good screening requirements, so that the screened soil is still mixed with various particle sizes. The soil particles of different sizes make the quality of the soil lower, which affects the quality of plant planting and the quality of soil experiments; in the prior art, there have been sieving machines for sieving soil, which has realized the mechanization and automatic sieving of soil. However, when using this kind of soil sieving machine to sieve the soil, many soils cannot achieve a good sieving effect when sieving because they are piled up in a ball. Many soil particles piled up together cannot be screened out through the screen, greatly reducing work efficiency

Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the invention clearer, the invention will be further elaborated below in conjunction with the accompanying drawings.

[0026] In this example, if figure 1 As shown, the soil rotary screening machine with variable speed and variable angle is characterized in that: the soil rotary screening machine includes a rotary screening cylinder 1, a vibrating feeder 2, a gear transmission system 3, a feed box 4, a storage box 5 and a support Rack 6;

[0027] The rotary screening cylinder 1 is fixed on the support frame 6 and the rotary screening cylinder 1 is arranged obliquely from the head end to the tail end. The rotary screening cylinder 1 includes 7 cylinders with different diameters, and the 7 cylinders are composed of Rotary screening cylinder 1 is connected end to end in turn from the head end to the tail end, and the diameters of the 7 cylinders gradually decrease from the head end to the tail end of the r...

Abstract

The invention discloses a soil rotary screening machine with variable speed and variable angle. The soil rotary screening machine includes a rotary screening cylinder, a vibrating feeder, a gear transmission system, a feeding box, a storage box and a support frame; the rotary screening cylinder It is fixed on the support frame and arranged obliquely from the head end to the tail end as a whole, including multiple cylinders with different diameters; the bottom of each cylinder is movable and fixed with screens with different apertures; the bottom of the front end of the rotary screening cylinder is equipped with lifting The bottom of each cylinder is equipped with a box with a weighing device; the front of the rotary screening cylinder is provided with a feeding plate, the feeding box is located above the feeding plate, and the feeding plate is fixed on the vibrating feeder. The invention replaces manual soil screening, and strengthens the vibration of the soil and the adjustment of the inclination angle and rotation speed of the rotary screening cylinder before screening, so as to achieve the highest soil screening efficiency, and at the same time, it can filter the soil after screening. It is very convenient to classify, weigh and collect all kinds of soil.

Description

technical field [0001] The invention belongs to the field of soil screening, in particular to a soil rotary screening machine with variable speed and variable angle. Background technique [0002] When selecting soil for planting plants or conducting soil research, due to the different specifications of the required soil and the requirements of research and analysis, it is often necessary to separate the soil samples through different particle size specifications, and sieve the soil into various sizes. granules, and different soil granules were used for experiments, and soil granules of appropriate size were used for the planting of plants. [0003] Traditionally, the operation of sieving soil is mainly done manually, which is very laborious and only suitable for sieving a small amount of soil. In the case of many requirements, manual screening is not only labor-intensive, but also low-efficiency, time-consuming and labor-intensive, and will not meet good screening requireme...
