Embodiment Construction

[0083] The invention discloses a combined sample making machine, how to reduce the labor intensity of operators on the premise that the accumulated materials are effectively cleaned when materials are accumulated at the striking plate of the crushing cavity.

[0084] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0085] see Figure 11-Figure 15 , Figure 11 A schematic structural view of the combined sample preparation machine provided by the embodiment of the present invention; Figure 12 for Figure 11 The t...

Abstract

The invention discloses a combined sample making machine which comprises a supplied material belt conveyor, a first-grade crushing mechanism, a first-grade division mechanism, a second-grade division mechanism, a second-grade crushing mechanism and a third-grade division mechanism, wherein the first-grade crushing mechanism is connected with the supplied material belt conveyor and comprises a striking plate, scrapers slidably matched with the striking plate, a connecting rod hinged with the scrapers, and a driving belt wheel; one end of the connecting rod is eccentrically hinged with the driving belt wheel; the first-grade division mechanism is connected with the first-grade crushing mechanism and passes through a vibration feeder; the second-grade division mechanism is connected with thefirst-grade division mechanism; the second-grade crushing mechanism is connected with a second-grade division sample retaining opening; and the third-grade division mechanism is connected with the second-grade crushing mechanism. The scrapers of the combined sample making machine provided by the invention can work automatically, so waste of human resources can be avoided; as the scrapers move up and down, materials drop off under the action of gravity and re-piling of the materials can be avoided; the operation frequency of the scrapers is controlled according to the rotating speed of the driving belt wheel; the moving frequency of the scrapers is higher than the manual operation frequency, therefore, a few of materials which are piled on the striking plate can be cleaned timely.

Description

technical field [0001] The invention relates to the technical field of coal machinery, in particular to a combined sample making machine. Background technique [0002] With people's demand for resources, the coal industry has been vigorously developed, and the resulting coal machinery has also developed rapidly. As a kind of coal machinery, the joint prototype machine plays an important role in coal experiments. [0003] Such as figure 1 As shown, the existing joint sample preparation machine generally includes a feeding belt conveyor 11 , a primary crushing mechanism 12 , a primary shrinking mechanism 13 , a secondary crushing mechanism 14 , a secondary shrinking mechanism 15 and a sample collection box 16 . Among them, the primary crushing mechanism 12 adopts a hammer crushing method; the secondary crushing mechanism 14 adopts a roller crushing method; the primary shrinking mechanism 13 and the secondary shrinking mechanism 15 both adopt a groove type shrinking mechanism....
