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, a first crushing chamber 2 is provided at the upper end of the box body 1, and two sets of symmetrically arranged guides are connected to the inner wall of the box body 1 below the first crushing chamber 2. Plate 3, the second crushing chamber 4 is installed inside the box body 1 below the guide plate 3, through the first crushing chamber 2 and the second crushing chamber 4 can achieve double crushing effect, improve the crushing rate of stone materials, the first crushing Chamber 2 first breaks larger stones into several smaller stones, and then crushes and crushes them into smaller stones by the second crushing chamber 4. The crushing effect is better. It is located under the second crushing chamber 4 1 is provided with a collection plate 5, the lower end of the collection plate 5 is provided with a discharge port 6, and the inner lower end of the box body 1 is provided with a f...

Embodiment 2

[0038] Such as Figure 1-8 As shown, a stone crushing and screening device includes a box body 1, and three groups of through-hole grooves 21 of the same size are provided inside the screening mechanism 8, and first Slide bar 22, filter sieve plate 23 is all installed in the inside of through-hole groove 21, and the screen mesh size of three groups of filter sieve plates 23 is different, by moving the position of three groups of filter sieve plates 23, the stone material with different volumes can be screened to obtain suitable stones of various sizes.

[0039] The middle part of the filter sieve plate 23 is equipped with a filter screen 24, and both sides of the filter sieve plate 23 are provided with partitions 25, through which the partitions 25 can effectively block the stones and prevent the stones from passing through the filter screen. The two sides of the plate 23 are separated from each other, so as to avoid entering the inside of the screening mechanism 8. Two sets ...

Abstract

The invention discloses a stone crushing and screening device, which comprises a box body. A first crushing chamber is arranged at the inner upper end of the box body. A second crushing chamber is arranged inside the box below the guide plate, a collecting plate is arranged inside the box below the second crushing chamber, and a discharge port is provided at the lower end of the collecting plate. The inner lower end of the box body is provided with a fixed plate, the fixed plate is located below the collecting plate, and the upper end surface of the fixed plate is fixedly connected with a screening mechanism. The present invention can automatically replace the screen by controlling the externally installed controller, which is simple and fast, saves the time for manual replacement of the screen, can achieve double crushing effects, and improves the crushing rate of stone materials, and if the crushing blade is damaged, only It is only necessary to replace a single damaged broken blade, which is simple, quick and cost-saving.

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...
