At the same time, building stone must still have sufficient strength and processability to be widely used in the construction industry. Building stone is the rock that makes up the earth's crust, which is mined and cut. From a microscopic and material fundamental perspective, rock is an aggregate of minerals. The mineral composition and rock texture of natural stone can determine its physical and chemical properties. The so-called rock texture refers to the size, shape and arrangement of the mineral particles that make up the rock, which of course also includes their cementation composition.

[0021] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0022] refer to Figure 1-3 The embodiment of the utility model discloses: a stone crushing device for construction that is convenient for adjusting the crushing fineness, comprising a frame 1, a first adjusting block 5 and a second adjusting block 6, a crushing bin is provided on the frame 1, a feed hopper 2 connected to the crushing bin is provided at the upper end of the frame 1, a discharge hopper 3 connected to the crushing bin is provided at the lower end of the frame 1, a crushing wheel 41 for crushing stones is provided in the crushing bin, the first adjusting block 5 and the second adjusting block 6 are symmetrically slidably arranged in the crushing bin and are located at both ends of the crushing wheel 41, the first adjusting block 5 and the second adjusting block 6 are respectively resisted by the crushing bin, a first screw 13 is rotatably arranged in the crushing bin, a second screw 14 with a thread opposite to that of the first screw 13 is connected to the first screw 13, the first screw 13 is threadedly penetrated on the first adjusting block 5 and threadedly driven with the first adjusting block 5, the second screw 14 is threadedly penetrated on the second adjusting block 6 and threadedly driven with the second adjusting block 6, and a first driving motor for driving the first screw 13 to rotate is provided on the crushing bin.

[0023] Specifically, the discharging device includes a sealing plate 7 and a sliding screw 8. The frame 1 is provided with a sliding channel 9 at the position of the discharging hopper 3. The sealing plate 7 is slidably arranged in the sliding channel 9. The sliding screw 8 is rotatably arranged in the sliding channel 9. The sealing plate 7 is sleeved on the sliding screw 8 and is threadedly transmitted with the sliding screw 8. The frame 1 is provided with a second driving motor for driving the sliding screw 8 to rotate.

[0024] Among them, when stone crushing is to be carried out, the stone is put into the crushing bin from the feed hopper 2, and then the first motor is started, driving the first screw 13 and the second screw 14 to rotate. The first screw 13 and the second screw 14 rotate, driving the first adjusting block 5 and the second adjusting block 6 to move closer to each other, thereby adjusting the crushing gap, thereby adjusting the coarseness of the crushing of the crushing wheel 41 and the stone. When the first adjusting block 5 and the second adjusting block 6 are closer, the crushing is finer, and vice versa, the coarser, so that the crushing can be adjusted according to the required crushing size, which greatly facilitates the operation and crushing of the staff.

[0025] In order to prevent dust from flying out of the feed hopper 2 during crushing and polluting the environment and affecting the health of the workers, a cover plate 11 is also included. The cover plate 11 is opened and closed at the upper end of the feed hopper 2. A rotating groove 16 is opened at one end of the feed hopper 2. A rotating shaft 17 is provided on the cover plate 11. The feed hopper 2 is provided with a rotating motor for driving the cover plate 11 to flip.

[0026] In order to facilitate feeding, an anti-collision plate 12 is also included. An anti-collision groove is provided on the cover plate 11. The anti-collision plate 12 is slidably arranged in the anti-collision groove and one end is located outside the anti-collision groove. A spring 15 is arranged in the anti-collision groove. The spring 15 is arranged in the anti-collision groove. One end of the spring 15 is connected to the anti-collision plate 12, and the other end of the spring 15 is connected to the inner wall of the anti-collision groove. When feeding, the cover plate 11 can be flipped and tilted, and then the material can be blocked. The material falls on the baffle and slides directly into the feed hopper 2, so as to better feed. When the material hits the anti-collision plate 12, the anti-collision plate 12 is forced to compress the spring 15, and the spring 15 performs buffering, thereby increasing the service life of the cover plate 11 and reducing the maintenance of the cover plate 11.

[0027] In order to facilitate the discharge, the first adjusting block 5 and the second adjusting block 6 are respectively provided with an inclined surface 10 for convenient material discharge. When the material is to be discharged, the first adjusting block 5 and the second adjusting block 6 slide to the inclined surface 10 and the discharge hopper 3, so that the material in the crushing bin can be discharged better and cleanly.
