Problems solved by technology

[0005] The screen setting of the existing stone crushing and screening device is relatively fixed, and it is not convenient to select screens of different sizes to screen the stones. It is necessary for the staff to manually replace the screen, which is prone to danger during the replacement process, and the existing stone crushing Most of the crushing blades of the screening device are set in one piece. After the damage, the whole blade needs to be replaced, which is wasteful and inconvenient to the production work. Therefore, we propose a stone crushing and screening device

Embodiment 1

[0033] Such as Figure 1-8 As shown, a stone crushing and screening device includes a box body (1). The upper end of the box body (1) is provided with a first crushing chamber (2), and the box body (1) is located below the first crushing chamber (2). There are two sets of symmetrically arranged first guide plates (3) connected to the inner wall of the inner wall, and a second crushing chamber (4) is arranged inside the box body (1) below the first guide plate (3). (2) and the second crushing chamber (4) can achieve a double crushing effect and increase the crushing rate of the stone. The first crushing chamber (2) first breaks the larger stone into several smaller stones, and then the second crushing chamber The second crushing chamber (4) is rolled and crushed into smaller stones, and the crushing effect is better. The inside of the box (1) under the second crushing chamber (4) is provided with a collecting plate (5), and the collecting plate ( The lower end of 5) is provide...

Embodiment 2

[0038] Such as Figure 1-8 As shown, a stone crushing and screening device includes a box body (1), three sets of through-hole grooves (21) of the same size are opened inside the screening mechanism (8), and the inner bottom of the three sets of through-hole grooves (21) The first sliding rod (22) is arranged on both sides of the end, and the filter sieve plate (23) is installed inside the through-hole groove (21). The screen meshes of the three sets of filter sieve plates (23) are of different sizes. The position of the filter sieve plate (23) can screen stones with different volumes to obtain stones of suitable size and volume.

[0039] A filter screen (24) is installed in the middle of the filter screen (23), and partitions (25) are arranged on both sides of the filter screen (23), through which the partitions (25) can effectively remove stones To prevent stones from detaching from both sides of the filter sieve plate (23) and from entering the inside of the screening mech...

Abstract

The invention discloses a building stone crushing-screening device. The building stone crushing-screening device comprises a box, wherein a first crushing room is arranged at the upper end inside thebox; the inner wall of the box positioned below the first crushing room is connected with two groups of first guide plates which are arranged symmetrically; a second crushing room is arranged inside the box below the first guide plates; a collection plate is arranged inside the box below the second crushing room; a discharging hole is formed in the lower end of the collection plate; a fixing plateis arranged at the lower end inside the box; the fixing plate is positioned below the collection plate; and the upper end face of the fixing plate is fixedly connected with a screening mechanism. Through the adoption of the building stone crushing-screening device, screen cloth can be automatically replaced easily and rapidly by controlling an external controller; the manual screen cloth replacing time is saved; the double crushing effect can be realized; and the building stone crushing rate is improved. If a crushing blade is damaged, only a single crushing blade needs to be replaced, so that easy and rapid operation is realized, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of stone crushing, in particular to a stone crushing and screening device. Background technique [0002] Stone refers to rock processing products used as materials. Stone is used as coarse aggregate and fine aggregate in the form of crushed stone and sand in the concrete construction industry. Stone is also used as filler and admixture in large quantities. In the road construction industry, the road cushion, base layer, surface layer, etc., in a broad sense, aggregates and mineral processing materials are all stone materials. Therefore, the current stone crushing and screening process is widely used in mining, metallurgy, chemical industry, casting, etc. The production lines of powder, mineral materials, aggregates, aggregates, etc. in industries such as building materials, water conservancy and hydropower, and transportation construction. Stone crushing and screening equipment and processes have a great imp...
